Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not meant to limit the present invention.

As shown in fig. 1 to 7, a test kit includes a case 100, a control member 200, a first sealing plate 300, a second sealing plate 400, and a drain tube 500.

The cartridge 100 is formed with a cavity 110 therein for receiving the attached functional components and for directly effecting mixing of the liquids to effect the test. Specifically, the cavity is divided into an upper chamber 111, a middle chamber 112, and a lower chamber 113 by providing a partition 120 and a filter layer (not shown).

The lower end of the draft tube 500 is positioned in the middle chamber 112, and the upper end passes through the partition 120 and extends into the upper chamber 111 to introduce the liquid in the upper chamber 111 into the middle chamber 112 through the draft tube 500.

The control member 200 is disposed in the upper chamber 111, and a lower surface of the control member 200 has an arc shape. By disposing the control member 200 in the upper chamber 111, a space for accommodating a substance to be tested is formed in the upper chamber 111 and the control member 200 and a cavity above the same. Meanwhile, the control member 200 is freely rotated by providing the lower surface of the control member 200 in the shape of an arc surface.

The inner wall of the upper chamber 111 is oppositely provided with a first sealing plate 300 and a second sealing plate 400.

The side wall of the control member 200 is formed with a notch 230 having a shape and size adapted to the first and

second sealing plates

300 and 400, and the notch 230 vertically penetrates to the lower surface of the control member 200, the upper edge of the control member 200 is in watertight fit with the inner wall of the upper chamber 111, and the notch 230 is in watertight fit with the edges of the first and

second sealing plates

300 and 400. By realizing watertight matching, the device is further convenient for filling liquid to-be-detected substances. Meanwhile, by providing the notch 230, when the control member 200 is moved to the present position, the liquid substance to be tested flows into the lower side of the control member 200 through the notch 230 and into the middle chamber 112 through the drain tube 500, thereby implementing the test reaction after mixing.

In the technical scheme of the utility model, in a specific using process, the first liquid and the second liquid for testing are mixed, reacted and tested in the middle chamber 112. The first liquid to be stored is stored in the upper chamber 111, and since the upper edge of the control member 200 is in watertight fit with the inner wall of the upper chamber 111 and the first sealing plate 300 and the second sealing plate 400, a structure for easily storing the liquid is realized. When the first liquid is required to enter the middle chamber 112, the whole test kit is shaken up and down, and the lower surface of the control member 200 is arc-surface-shaped, so that the matching of the notch 230 on the control member 200 and the first sealing plate 300 and the second sealing plate 400 is staggered, the penetrating structure of the notch 230 is communicated with the upper part and the lower part of the control member 200, and the first liquid flows into the lower part of the control member 200 through the notch 230 and flows into the middle chamber 112 from the drainage tube 500 to realize mixing.

In some embodiments, the upper surface of the control member 200 is provided with a silicone gel layer 210 to achieve a watertight fit with the first sealing plate 300, the second sealing plate 400, and the inner wall of the upper chamber 111 through the silicone gel layer 210.

Through setting up silica gel layer 210 to utilize the material characteristic of silica gel, realize the watertight effect of contact department. Since the silicone rubber has elasticity and low surface roughness, a watertight effect can be achieved when the inner wall of the upper chamber 111 is in contact with the silicone rubber.

In some embodiments, the bottom of the control member 200 forms a recess 220 to receive the upper end of the extended protruding draft tube 500.

By providing the recess 220 at the bottom of the control member 200 to accommodate the upper end of the draft tube 500, interference with the protruded draft tube 500 is prevented.

In some embodiments, the bottom and edges of the recess 220 are both curved to create a smooth contact surface to avoid interference and drag during sliding contact.

In some embodiments, the upper end of the draft tube 500 is spaced from the upper surface of the barrier 120 by 2mm to 4mm, and the distance between the outer wall of the draft tube 500 and the side wall of the recess 220 is greater than the distance between the upper end of the draft tube 500 and the barrier 120.

By making the upper end of the draft tube 500 higher than the upper surface of the partition plate 120 by 2mm to 4mm, it is ensured that a small amount of liquid does not directly enter the draft tube 500 when flowing around the upper end of the draft tube 500. Meanwhile, the distance between the outer wall of the draft tube 500 and the side wall of the recess 220 is made larger than the distance between the draft tube 500 and the partition 120, so that the control member 200 does not interfere when rotating.

In some embodiments, a fiber mass 600 is disposed within the drain tube 500. The fiber mass 600 is provided for the purpose that when a small amount of liquid enters the draft tube 500, it will be absorbed by the fiber mass 600 and not enter the middle chamber 112. When only a large amount of liquid is introduced, the fiber mass 600 may not be absorbed further, and may enter the middle chamber 112. Thus, mixing and reaction can be completed only when a large amount of the first liquid enters under the action of strong force.

Further, in some embodiments, the fiber mass 600 is made of cotton.

In some embodiments, a first stopper 700 is disposed on a sidewall of the upper chamber 111, and the first stopper 700 is located above the control member 200 and close to the second sealing plate 400.

By providing the first limiting member 700, when the control member 200 is swayed up and down, one end of the control member 200 close to the first limiting member 700 is prevented from moving up and only moving down.

In some embodiments, the sidewall of the upper chamber 111 is provided with a second stopper 800, and the second stopper 800 is located above the control member 200 and close to the first sealing plate 300.

By providing the second position-limiting member 800, a limitation is provided for the upward movement of the control member 200 at the position, so that the control member 200 is prevented from easily moving upward at the position, and can move upward only under a strong force. Further, in some embodiments, a surface of the second limiting member 800 on a side close to the control member 200 is formed as a concave and arc-shaped limiting surface 810, and a distance between a lower end edge of the limiting surface 810 and an inner wall of the upper cavity 111 is 0.8mmm to 1.2 mm. Through the concave structure arranged in the arc surface shape, the corresponding position of the control member 200 can easily slide without strong interference and retardation. Setting the spacing to 0.8mm-1.2mm means that the control member 200 does not move up in a static or light sloshing condition.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
