CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on and claims the benefit of priority from Chinese Patent Application No. 2020101162206, filed on 25 Feb. 2020, the entirety of which is incorporated by reference herein.

TECHNICAL FIELD

The disclosure relates to the field of health protection products, and in particular to a waterseal virus-killing mask.

BACKGROUND

Outbreaks of 2019 Novel Coronavirus Pneumonia (NCP), also referred to as COVID-19, have gain world's attention recently. Persons infected with this virus have symptoms of varying degrees. The infected persons will have a fever or slight cough, or will catch pneumonia, or even die. The novel pneumonia coronaviruses are mainly spread through breathery droplets. A mask can be worn to avoid breathing in the air that contains novel coronaviruses. Therefore, wearing a mask is an important method for preventing the infection of NCP. However, most existing masks filter out viruses in the air through filtering layers which cannot capture and kill the viruses, thus having a limited effect. Moreover, the virus blocking effect of such a mask keeps diminishing over time, so the mask needs to be changed after one or several times of use. Under the current epidemic situation, there is a severe shortage of masks.

SUMMARY

The disclosure is to at least resolve the foregoing technical problem in the prior art to some extent. For this, the disclosure provides a waterseal virus-killing mask. In the mask, disinfectant is provided in a U-shaped tube, so that novel pneumonia coronaviruses in the air flowing through the U-shaped tube are killed by the disinfectant, the disinfectant in the air is then filtered out by a first filter mesh, and the air is eventually inhaled by a human, thereby effectively protecting the physical health of a wearer. In addition, the mask has relatively long service life and can be repeatedly used, thereby resolving the problem that a large number of conventional disposable masks are used.

A waterseal virus-killing mask according to an embodiment of the disclosure includes: a mask body with a breather valve disposed on an outer surface of the mask body, two elastic ear loops disposed on two sides of the mask body, respectively, and a liquid virus-killing assembly. The mask includes a U-shaped tube within which disinfectant is provided, a disinfectant replenishing tube vertically disposed at an upper end in the middle of the U-shaped tube, a first horizontal straight tube disposed at one end of the U-shaped tube and including a left end in communication with a port of the breather valve and a right end within which a first filter mesh used to separate water and air is disposed, and a second horizontal straight tube disposed at the other end of the U-shaped tube.

The waterseal virus-killing mask according to the embodiment of the disclosure at least has the following technical effects. By disposing the liquid virus-killing assembly at the port of the breather valve, as a wearer inhales air, novel coronaviruses in external air entering the U-shaped tube through the second horizontal straight tube will be killed by the disinfectant when the external air flows through the U-shaped tube. The disinfected air then passes through the first filter mesh to have the disinfectant contained in the air filtered, so that the air eventually inhaled by the wearer is disinfected clean air without disinfectant, thereby effectively protecting the physical health of a wearer. As the wearer exhales air, the exhaled air enters the U-shaped tube through the first horizontal straight tube to be disinfected by the disinfectant, thereby ensuring that the exhaled air contains no virus. Particularly, when a person infected with NCP wears the mask, it can be ensured that air exhaled by the person contains no virus, thereby reducing the risk of cross infection. The embodiment of the disclosure can achieve effective virus-killing and adequate protection. The mask can be repeatedly used and has long service life, thereby resolving the problem that a large number of conventional disposable masks are used. Moreover, with the provision of the disinfectant replenishing tube, when the disinfectant in the U-shaped tube is reduced to a particular amount after a period time of use, the U-shaped tube can be replenished with the disinfectant through the disinfectant replenishing tube.

According to some embodiments of the disclosure, the U-shaped tube is a transparent tube provided with a scale for observing the remainder of the disinfectant.

According to some embodiments of the disclosure, an air inlet and outlet tube is disposed at the port of the breather valve, a first external thread is disposed at an end portion of the air inlet and outlet tube away from the breather valve, and a first internal thread matching the first external thread is disposed in a left end portion of the first horizontal straight tube.

According to some embodiments of the disclosure, a third straight tube is formed by bending outward a left end of the U-shaped tube bends outward by 90°, the first horizontal straight tube is detachably connected to the third straight tube, and the first filter mesh is disposed at a connection between the first horizontal straight tube and the third straight tube.

According to some embodiments of the disclosure, the first horizontal straight tube is provided, on an outer surface of the right end of the first horizontal straight tube, with a second external thread, and a second internal thread matching the second external thread is disposed in a left end portion of the third straight tube.

According to some embodiments of the disclosure, a right end portion of the first horizontal straight tube is inserted in a left end of the third straight tube, a sealing sleeve is sleeved over the right end portion of the first horizontal straight tube, and the sealing sleeve enables the first horizontal straight tube to be in interference fit in the third straight tube.

According to some embodiments of the disclosure, a second filter mesh used to separate water and air is disposed within a left end of the second horizontal straight tube.

According to some embodiments of the disclosure, a fourth straight tube is formed by bending outward a right end of the U-shaped tube bends outward by 90°, the left end of the second horizontal straight tube is threaded to a right end of the fourth straight tube, and the second filter mesh is disposed at a connection between the second horizontal straight tube and the fourth straight tube.

According to some embodiments of the disclosure, a filter sheet is disposed between the outer surface and an inner surface of the mask body, a positioning post is disposed on a right side of the inner surface of the mask body, and the filter sheet is connected to the positioning post.

Additional aspects and advantages of the disclosure will be partially appreciated and become apparent from the description below, or will be well learned from the practices of the disclosure.
