Abstract

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

First claim

We claim:

1. A waterseal virus-killing mask, comprising:
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, comprising:
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.

2. The waterseal virus-killing mask of claim 1 , wherein the U-shaped tube is a transparent tube provided with a scale for observing the remainder of the disinfectant.

3. The waterseal virus-killing mask of claim 1 , wherein 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.

4. The waterseal virus-killing mask of claim 1 , wherein a third straight tube is formed by bending outward a left end of the U-shaped tube 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.

5. The waterseal virus-killing mask of claim 4 , wherein 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 which is matched with a second internal thread disposed in a left end portion of the third straight tube.

6. The waterseal virus-killing mask of claim 4 , wherein 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.

7. The waterseal virus-killing mask of claim 1 , wherein a second filter mesh used to separate water and air is disposed within a left end of the second horizontal straight tube.

8. The waterseal virus-killing mask of claim 7 , wherein a fourth straight tube is formed by bending outward a right end of the U-shaped tube by 90°, the left end of the second horizontal straight tube is threaded with 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.

9. The waterseal virus-killing mask of claim 1 , wherein 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.
