This application claims the priority of China patent application No. 201920522185.0 filed on Apr. 17, 2019, disclosure of which is hereby incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present disclosure relates to the technical field of combustion heating stoves, and more particularly relates to a stove.

BACKGROUND

As a type of widely used cookware, stoves are being increasingly used by users in outdoor activities such as camping and explorations. In outdoor activities such as camping and explorations, users need to stay in an enclosed space such as a tent, so the stove is required to be able to provide safety in addition to portability. When an existing stove is used in an enclosed space such as a tent in the wilderness or the like, the stove would consume the oxygen in the tent, and toxic gas produced in the combustion process of the fuel is easily leaked in the tent, posing a great danger to the users.

SUMMARY

It is an object of the present disclosure to provide a stove that allows a user to safely use the stove in an enclosed space.

To achieve this object, the present disclosure adopts the following solutions.

There is provided a stove that includes a stove body, an air inlet channel, and an exhaust channel.

When the stove body is used in an enclosed space, an air inlet end of the air inlet channel is in communication with an outside of the enclosed space, and a connection end of the air inlet channel is in communication with an air inlet of the stove body. The air inlet channel is operative to introduce air into the stove body from the outside of the enclosed space. A connection end of the exhaust channel is in communication with an exhaust port of the stove body, and an exhaust end of the exhaust channel is in communication with the outside of the enclosed space, whereby the exhaust channel is operative to discharge an exhaust gas in the stove body out of the enclosed space.

In some embodiments, the stove is provided with an air intake adjusting device configured to adjust an opening degree of the air inlet, and is further provided with a stove door arranged on a front side of the stove body. The openability of the stove door is associated with an opening degree of air inlet, and only when the opening degree of the air inlet is 0% or the air inlet is totally closed is the stove door openable by a user.

In some embodiments, the air intake adjusting device comprises: a baffle rotatably arranged inside the connection end of the air inlet channel through a rotating shaft; an adjusting rod extending from a front side of the stove body to a rear side of the stove body and rotatably connected to the stove body; and a transmission assembly, where one end of the adjusting rod is connected to an operating bar, and another end of the adjusting rod is connected to the rotating shaft via the transmission assembly. The transmission assembly is operative to convert a rotary motion of the operating bar performed by a user into a rotary motion of the baffle, and the stove door is not confined by the operating bar only when the air inlet is completely blocked by the baffle thereby preventing external air outside of the enclosed space from entering the stove body.

In some embodiments, the transmission assembly comprises: a first gear fixedly connected to one end of the rotating shaft; and a second gear fixedly connected to the other end of the adjusting rod. The first gear and the second gear are engaged with each other and are operative to transfer a rotary motion of the first gear in a plane of the first gear into a rotary motion of the second gear in a plane of the second gear.

In some embodiments, a plane of the first gear is perpendicular to the rotating shaft, a plane of the second gear is perpendicular to the adjusting rod, the plane of the first gear is perpendicular to the plane of the second gear, and the rotating shaft is perpendicular to the adjusting rod. When a plane of the baffle is perpendicular to a longitudinal axis of the air inlet, the operating bar is perpendicular to a width of the stove door, and the stove door is not confined by the operating bar only when the operating bar is at the position perpendicular to the width of the stove door.

In some embodiments, the operating bar is confined to move back and forth between a position parallel to the width of the stove door and a position perpendicular to the width of the stove door. The position of the operating bar parallel to the width of the stove door corresponds to a position of the baffle parallel to the longitudinal axis of the air inlet, and the position of the operating bar perpendicular to the width of the stove door corresponds to a position of the baffle perpendicular to the longitudinal axis of the air inlet. In some embodiments, there are provided one or more air supplement zones in the stove body, where the air supplement zones are in communication with the connection end of the air inlet channel.

When the stove body is used, air entering the stove body via the air inlet may pass through the air supplement zones to be discharged out from the exhaust port.

In some embodiments, there are provided two air supplement zones, including a first air supplement zone and a second air supplement zone. The air entering the stove body via the air inlet successively passes through the first air supplement zone and the second air supplement zone and then is discharged out from the exhaust port.

In some embodiments, a stove door is arranged on a front side of the stove body. The air inlet is disposed on a rear side of the stove body. An air guide plate is arranged in the stove body to separate an interior of the stove body into an upper part and a lower part. The first air supplement zone is located on a front side of the lower part of the air guide plate, and the second air supplement zone is located on a rear side of the upper part of the air guide plate.

In some embodiments, the first air supplement zone is in communication with the connection end of the air inlet channel via a first air supplement channel.

The first air channel includes an ash box and a first air supplement pipe that are in communication with each other. The ash box is disposed in a bottom of the stove body and is in communication with the first air supplement zone via an opening in the bottom of the stove body. One end of the first air supplement pipe is in communication with the connection end of the air inlet channel, and another end of the first air supplement pipe is in communication with a side of the ash box. There is provided an ash tray at a bottom of the ash box, and the ash tray is operative to open or close an opening in the bottom of the ash box.

In some embodiments, the second air supplement zone is in communication with the connection end of the air inlet channel via a second air supplement channel.

The second air supplement channel includes a plurality of second air supplement pipes. An end of each of the plurality of second air supplement pipes is in communication with the connection end of the air inlet channel, and another end of the second air supplement pipe extends into the stove, and an air venting hole is opened in a sidewall of the portion of each of the plurality of second air supplement pipes that extends into the stove body.

In some embodiments, the stove body is provided with an air intake adjusting device, which can adjust the opening degree of the air inlet.

In some embodiments, the air intake adjusting device further includes:

a baffle, rotatably arranged inside the connection end of the air inlet channel via a rotating shaft; and

an adjusting rod, extending from a front side of the stove body to a rear side of the stove body and slidably connected to the stove body. An end of the adjusting rod is connected to an operating handle, and another end of the adjusting rod is connected to the rotating shaft via a transmission assembly, where the adjusting rod when sliding is operative to drive the baffle to rotate to adjust the opening degree of the air inlet.

In some embodiments, the first air supplement zone is in communication with the connection end of the air inlet channel via a first air supplement channel.

An air supplement adjusting device is arranged in the stove body and is operative to adjust an opening degree of a communicating port between the first air supplement channel and the stove body.

In some embodiments, two casings are further included, separately and rotatably connected to the stove body, and symmetrically arranged at the top of the stove body.

The two casings when fitted together are operative to enclose a closed baking space on the top of the stove body.

In some embodiments, a horizontal elongated hole is defined in a front side of the stove body, and the stove further includes a stove cover operative to be inserted into the stove body via the elongated hole to fully seal up a fire vent in a top surface of the stove body as well as the elongated hole. The stove cover is further detachable from the stove body by being pulled off via the elongated hole defined in the front side of the stove body.

The present disclosure provides the following beneficial effects.

On the basis of the stove body, the air inlet channel works in coordination with the exhaust channel, so that when the stove is used in an enclosed space such as a tent, air can be introduced from the outside and smoke produced from combustion can be discharged to the outside. Thus, oxygen in the enclosed space is not consumed, so the problem that the smoke and the like are leaked in the enclosed space is solved, enabling the user to safely use the stove in the enclosed space.

On the basis of the air inlet, two air supplement zones are arranged in the stove body, so that during the whole combustion process of the fuel in the stove body, three times of ventilation are performed to support the combustion, thereby effectively avoiding the problem of the production of harmful gas due to insufficient combustion of the fuel.
