Technical Field

[0001] The utility model relates to the technical field of rapid test kits, and in particular to a COVID-19 household rapid test kit that is convenient for stacking and stacking. Background Art

[0002] The COVID-19 Home Rapid Test Kit is a new coronavirus antigen test kit suitable for self-testing in a home environment.

[0003] The COVID-19 home rapid test kit is assembled by splicing a test kit body and a test kit cover. When in use, the test kit cover is opened to expose the reagents in the test kit body, making it easy to take out and use. After use, the test kit cover is closed and the test kit body is used to prevent the internal reagents from being waterproof and dusty.

[0004] However, in actual use, it was found that traditional COVID-19 home rapid test kits are generally stacked in order to save space. However, after stacking, the overall height of the test kit group increases and the center of gravity rises. In the process of taking and placing a single test kit, it is easy for the test kit group to tilt and collapse, thereby causing damage to the reagents stored inside the test kit. Therefore, it is necessary to design a test kit suitable for stacking. Utility Model Content

[0009] Furthermore, a circular filter screen is fixedly installed at the upper cavity opening of the circular air cavity, and the circular filter screen is designed to be flush with the cavity bottom of the square cavity.

[0010] Furthermore, a plurality of second exhaust holes are formed through the two opposite outer walls of the reagent box cover, and the plurality of second exhaust holes are respectively opposite to the corresponding first exhaust holes, and the plurality of second exhaust holes are respectively connected to the corresponding one-way exhaust valve input ports.

The surface of the iron sheet 14 is flush with the inner groove wall of the limiting slide groove 12, and does not affect the sliding insertion of the limiting slide bar 13. The limiting slide bar 13 is fixedly installed on the other side wall of the test kit body 1, and the limiting slide bar 13 is adaptively slidably installed in the limiting slide groove 12. The limiting slide bar 13 is embedded and fixedly installed on the side away from the test kit body 1. Two magnetic sheets 15 are respectively fixedly installed with corresponding The iron sheet 14 is magnetically connected, and the magnetic adsorption of the magnetic sheet 15 and the iron sheet 14 can improve the sliding installation stability of the limiting slide bar 13 and the limiting slide groove 12, while not affecting the disassembly and removal of a separate test kit. A square cavity 21 is provided at the center of the top of the test kit cover 2, and a circular air cavity 22 is provided at the bottom of the square cavity 21. The outer ring walls of the circular air cavity 22 are connected to exhaust pipes 24, and the ends of the two exhaust pipes 24 are connected to one-way exhaust valves 25, so that the air pressed into the square cavity 21 can only be discharged in one direction. Under the premise that the original airway volume does not change, the internal air is reduced, which will reduce the internal air pressure, thereby forming an air pressure difference with the outside world, and the output ends of the two one-way exhaust valves 25 extend through to the outside of the test kit body 1.

[0028] Example 2

[0029] Reference Figure 1-5 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: the two opposite inner side walls of the reagent box body 1 are respectively penetrated by the outer side wall to open a plurality of first exhaust holes 11, the bottom of the inner cavity of the reagent box body 1 is penetrated by the lower bottom of the reagent box body 1 to open a notch 16, and a circular filter screen 23 is fixedly installed at the upper cavity opening of the circular air cavity 22 to prevent large particles of foreign matter from entering the circular air cavity 22 and blocking the exhaust channel. The circular filter screen 23 is designed to be flush with the cavity bottom of the square cavity 21, and does not affect the insertion of the square base 3 into the square cavity 21. The two opposite outer side walls of the reagent box cover 2 are penetrated by the inside to open a plurality of second exhaust holes 26, and a plurality of second rows of The air holes 26 are respectively opposite to the corresponding first exhaust holes 11 to ensure that the air in the exhaust channel is eventually discharged from the outside of the reagent box body 1. A number of second exhaust holes 26 are respectively connected to the corresponding one-way exhaust valve 25 input ports. A card block 27 is fixedly installed at the end of the reagent box cover 2, and the card block 27 is inserted into the notch 16. The width of the card block 27 is consistent with the cavity width of the notch 16, and the thickness of the card block 27 is less than the cavity depth of the notch 16, so that the reagent box cover 2 can be easily rotated open by the card block 27. A square base 3 is fixedly installed at the center of the lower bottom of the reagent box body 1, and the lower bottom of the square base 3 is adapted to be inserted into the square cavity 21 at the top of another reagent box cover 2.

[0030] The remaining structures are the same as those of Example 1.

[0031] First, the square base 3 at the bottom of the upper reagent box body 1 is inserted into the square cavity 21 at the top of the lower reagent box cover 2. The air in the square cavity 21 will enter the exhaust pipe 24 through the circular air cavity 22, pass through the one-way exhaust valve 25, and then be discharged from the second exhaust hole 26 and the first exhaust hole 11, so that the air pressure inside the exhaust channel composed of the circular air cavity 22, the exhaust pipe 24 and the one-way exhaust valve 25 drops, forming a negative pressure difference with the outside air, so that the upper and lower layers of the reagent box are adsorbed and fixed to each other, thereby improving the stability when stacking;

[0032] Secondly, the left and right stacks of reagent kit bodies 1 are brought close to each other, and the adjacent limit slides 13 are slidably inserted into the corresponding limit slide grooves 12, so as to further improve the stability of the left and right stacks of reagent kits when they are stacked in time. In order to further improve the sliding stability of the limit slides 13 and the limit slide grooves 12 so that the limit slides 13 will not slide freely in the limit slide grooves 12, two iron sheets 14 are embedded and fixedly installed on the inner groove wall of the limit slide grooves 12, and two magnetic sheets 15 are embedded and fixedly installed on the side of the limit slide 13 away from the reagent kit body 1. The two magnetic sheets 15 are magnetically connected to the corresponding iron sheets 14 respectively, so as to ensure that the limit slides 13 and the limit slide grooves 12 are slidably installed.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents.
