a pump 4 having a sphere stopper 41 at its top is supported by a compressed spring 42 to press against the front end of a passage opening 411 , and said compressed spring presses against a sealing stopper 43 , and one end of said sealing blocking stopper is plugged into a piston 44 and a relay push pipe 45 presses against the bottom of said sealing stopper 43 , while said relay push pipe 45 covers the lower end of said relay push pipe by a main push pipe 46 , and the front end of the blocking edge 461 of the main push pipe 46 is sleeved from a main push pipe 45 by a bottle stopper 49 and embedded into the bottom of the pump 4 such that the bottle stopper 49 supports said piston 44 and the blocking edge 461 of the main push pipe 46 while keeping an appropriate distance between the piston 44 and the blocking edge 461 of the main push pipe 46 and pressing against the blocking edge 461 of the main push pipe 46 to prevent the main push pipe 46 from falling out . in the meantime , the lower end of the main push pipe 46 is embedded into the fixed hole 223 at the bottom of the storage bottle 2 and the outer periphery of the main push pipe 46 has a secondary spring 47 being supported between the bottom of the pump 4 and the bottom of the storage bottle 4 , so that the handle connecting pipe a , push member 26 , pump 4 , main push pipe 46 , connecting pipe 12 , and mop 1 form a longitudinal line vertical to a central line , and the relay push pipe 45 , main push pipe 46 , fixed hole 223 , flow hole 221 , and the nozzle opening 242 of the outlet nozzle 24 constitute a liquid detergent passage . please refer to fig1 . before the mop according to the present invention is used , inject the liquid detergent into the storage bottle 2 through the inject hole 252 and seal the bottle with a stopper 253 , and follow the procedure as follows : ( 1 ) adjust the handle connecting pipe a according to the user &# 39 ; s height or requirements and secure it to the sectional handle . to prevent the pump 4 in the storage bottle 2 from being rotated when securing the handle , use the upward pushing force of the compressed spring 42 in the pump 4 and the secondary spring 47 at lower end of the pump to prop the push member 26 towards the surface of the central hole 2541 at the top of the interior of the storage bottle 2 , and engage the latch serration 262 on the push member 262 and the fixed serration 255 on the surface of the central hole 2541 such that the fixed push member 26 and the handle connecting pipe a will not rotate as the sectional handle is being secured . ( 2 ) please refer to fig4 and 4a . before the mop of the present invention has ever been used , there is no liquid detergent w in the pump 4 . when the handle a erects the storage bottle 2 to a vertical position , the handle is in the most power saving condition for compressing the pump 4 , therefore when the handle connecting pipe a compresses the push member 26 , the pump 4 sinks and the main push pipe 46 relatively enters into the pump 4 while pushing the sealing stopper 43 up and separating the piston 44 and leaving a gap b behind . please refer to fig5 and 5a . the relay push pipe 45 keeps on being pushed forward by the main push pipe 46 and the blocking edge 461 of the main push pipe 46 in turn pushes the piston 44 to squeeze the air in the squeezing chamber 48 in the pump 4 . the sphere stopper 41 squeezed by the air pressure on one hand , and pushed by the compressed spring 42 on the other hand clogs the passage opening 411 . the air is compressed by the piston 44 , and enters through the gap b into the relay push pipe 45 , main push pipe 46 , flow hole 221 . and nozzle opening 242 of outlet nozzle 24 , and then discharge the air . ( 3 ) please refer to fig6 and 6a . if the user no longer pushes the handle a , then the resuming forces of the compressed spring 42 in the pump 4 and the secondary spring 47 are used to push the pump 4 upward , while the piston 44 uses the friction of the inner wall of the pump 4 to keep the piston 44 still in the original position . the sealing stopper 43 drops to the position of the piston 44 and clog the gap b . at that time , since the pump 4 rises , it is equivalent to the drop of the piston 44 to extract the air in the squeezing chamber 48 of the pump 4 such that the sphere stopper 41 is separated from the passage opening 411 by the suction and forms a gap b . such suction sucks the liquid detergent w by the suction pipe 32 through the curved pipe 3 , passage 33 , passage opening 411 , gap b ′ and then into the squeezing chamber 48 of the pump 4 for temporary storage . ( 4 ) the liquid detergent w temporarily stored in the squeezing chamber 48 is blocked by the sealing between the sealing stopper 43 and the piston 44 , and squeezed by the piston 44 according to the previous step ( 2 ), which is also shown in fig5 and 5a . the liquid detergent is squeezed into the relay push pipe 45 through the gap b between the sealing stopper 43 and the piston 44 , and then sprayed out through the main push pipe 46 , flow hole 221 , and nozzle opening 242 of the outlet nozzle 24 . ( 5 ) in the foregoing step , the back and forth movement of the handle can squeeze and resume the pump 4 to spray the required quantity of the liquid detergent . ( 6 ) the handle is usually set to an appropriate angle to use the mop ( as shown in fig7 ), and the mop 1 is placed in front of the user to facilitate the movement of the mop . therefore the force exerting on the pump 4 produced by the inclination of the handle plus the resisting forces by the compressed spring 42 and the secondary spring 47 will not sufficient to squeeze the pump 4 when a pushing force is applied onto the mop when it is in use . ( 7 ) please refer to fig8 . to prevent the mop of the present invention from dripping the liquid detergent remained in the nozzle opening or spraying the detergent by accidentally trigger the handle to squeeze the pump 4 , the outlet nozzle 24 can be lifted upward to detach the outlet passage 243 from the flow hole 211 and seal by the anti - leakage spacer 23 to prevent further spray of liquid detergent . please refer to fig9 for the second preferred embodiment of the present invention . in the figure , the pump 4 ′ has a structure identical to the pump 4 of the first preferred embodiment . the difference resides on that the position of the pump 4 ′ has an inverted position of the previous pump 4 , and the structure of the pump 4 ′ is to extend the passage opening 411 ′ of the pump 4 ′ to a suction pipe 32 ′, and be embedded and limited on a limit pillar c protruded from the storage bottle 2 , and such suction pipe 32 ′ at its bottom has a suction opening 321 ′, the push member 26 identical to that of the first embodiment having a limit member 263 directly embedded into the main push pipe 46 ′ of the pump 4 , and said main push pipe 46 ′ connects a conveying pipe d to an outlet passage 243 ′ of the outlet nozzle 24 ′ and is fixed into the axial hole 254 of the fixed bottle cover 25 . the secondary spring 47 ′ is placed in said axial hole 254 and a press board a 1 fixed on the handle connecting pipe presses said secondary spring 47 ′. by means of passing the handle connecting pipe a into a limit cover e and securing it above the axle hole 254 of the fixed bottle cover 25 such that the secondary spring 47 ′ can be compressed and resumed in the axial hole 254 by the back and forth squeezing movement of the handle . ( 1 ) please refer to fig1 . if the handle connecting pipe a pushes the push member 62 to sink the main push pipe 46 ′, and the main push pipe 46 relatively enters into the pump 4 ′, while pressing the sealing stopper 43 down , and separating the piston 44 to form a gap b between them . please refer to fig1 . said relay push pipe 45 keeps on being pushed forward by the main push pipe 46 ′, and the blocking edge 461 pushes the piston 44 to squeeze the liquid detergent w in the squeezing chamber 48 of the pump 4 ′. the sphere stopper 41 is pressed by the pressure on one hand , and pushed by the compressed spring 42 on the other hand to block the passage opening 411 ′. therefore , the liquid detergent w is compressed by the piston 44 to enter into said gap b and then into the relay push pipe 45 , main push pipe 46 , conveying pipe d , the outlet passage 243 ′ of the outlet nozzle 24 ′, and then discharged from the nozzle 242 ′. ( 2 ) if the user no longer pushes the handle a , but resumes the movement as shown in fig1 to the movement as shown in fig9 . therefore , the resuming force by the compressed spring 42 and the secondary spring 47 ′ in the pump 4 ′ is used to push the main push pipe 46 ′ up , while the pistons 44 uses the friction on the inner wall of the pump 4 ′ to drop the piston 44 to the position of the sealing stopper 43 and blocks the gap b . at that time , since the main push pipe 46 ′ rises , it relatively makes the piston to pump the liquid detergent w in the squeezing chamber 48 of the pump 4 ′ and separates the sphere stopper 41 from the passage opening 411 ′ by said suction to form a gap . such suction sucks the liquid detergent w through the suction opening 321 and the suction pipe 32 ′ and the gap b ′ into the squeezing chamber 48 of the pump 4 ′ for temporary storage . ( 3 ) the required quantity of liquid detergent can be sprayed by the back and forth squeezing and resuming movement of the handle on the bump 4 ′ as described in the previous step . please refer to fig1 and 13 . the mop 1 comprises a board body 13 and a board surface 14 ; a serrated latch groove 131 disposed respectively at the front and the rear ends of the board body 13 , and a plurality of soft clipping boards 132 disposed thereon ; a board surface 14 having an aslant sliding track 141 inclined towards both sides of the board surface 14 ; two n - shape contractible support rod 15 disposed on both sides of the opening end respectively having an vertically upward protruded ear 151 and a sliding rod 152 extended towards the inner side . when the n - shape contractible rod 15 is disposed at the bottom of the board body 13 , the protruded ear 151 exactly passes through the serrated latch groove 131 and latches the protruded ear 151 into the latch groove 1311 of the serrated latch groove 131 by the elasticity of the n - shape contractible support rod 15 . the aslant sliding track 141 exactly presses against the sliding rod 152 of the n - shape support rod 15 by means of combining the board surface 14 and the board surface . when the protruded ear 151 on both sides of the n - shape contractible support rod 15 is held inward , said protruded ear 151 will separate from the latch groove 1311 of the serrated latch groove 131 and contract the n - shape contractible support rod 15 towards both sides of the mop 1 . if the protruded ear is released , the n - shape contractible support rod 15 is latched in the latch groove 1311 . the aslant sliding track 1411 is used to tilt the sliding rod 152 aslant to both sides . please refer to fig7 . if the length of the cloth exceeds the length of the board body of the mop 1 , the n - shape contractible support rod 15 is used to pass the cleaning cloth 5 into the two side pockets and extend outward . the outwardly aslant n - shape contractible support rod 15 guides both ends of the cleaning cloth to attached on the same plane as the cleaning cloth attached on the foregoing board surface 14 ( as shown in fig1 a ) to improve the effect of using the whole pieces of the cleaning cloth 5 . please refer to fig1 . the mop 1 has a soft clipping board 132 for engaging the polyester cloth or other cleaning cloth 6 for having a multiple effect on the applications . while the invention has been described by way of example and in terms of a preferred embodiment , it is to be understood that the invention is not limited thereto . to the contrary , it is intended to cover various modifications and similar arrangements and procedures , and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures .
