DETAILED DESCRIPTION

[0022] To make the purpose, technical scheme and advantages of the embodiment of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is a part of the embodiment of the present application, rather than all of the embodiments. The components of the embodiment of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiment of the present application. It should be noted that, in the absence of conflict, the various features in the embodiment of the present application can be combined with each other, and the combined embodiment is still within the protection scope of the present application.

[0023] When the portable turbidity meter is in use, it is necessary to keep the portable turbidity meter stable. A structure for clamping the test bottle will be provided in the test slot. At the same time, the staff needs to insert the entire measuring bottle into the test slot. In this way, it is difficult to take out the test bottle from the test slot. In view of the above-mentioned problems in the prior art, an embodiment of the present application provides a portable turbidity meter. An elastic component 14 is provided at the bottom of the test slot 12. When the light shielding cover 30 is opened, the test bottle 40 automatically pops out, making it easy to take out the test bottle 40, thereby improving the detection efficiency.

[0024] Reference Figure 1 A portable turbidity meter provided in an embodiment of the present application includes: a main body, the main body includes a detection area 10 and an operation area 20, a detection slot 12 is provided in the detection area 10, a detection unit is provided on the side wall of the detection slot 12, the detection unit is used to detect the sample to be tested filled in the detection bottle 40 in the detection slot 12, and the operation area 20 is used to control the operation of the detection unit; an elastic component 14 is provided at the bottom of the detection slot 12, and a light shielding cover 30 is provided at the opening of the detection area 10, and the light shielding cover 30 presses the glass bottle into the detection slot 12 when closed.

[0025] In the embodiment of the present application, a plurality of buttons with different functions are provided in the operation area 20 to perform different operations on the portable turbidity meter. A display screen is also provided in the operation area 20 to display the test results.

[0026] The test bottle 40 is a transparent glass bottle, and the turbidity of the reagent is detected by infrared rays, and it needs to be kept stable during the test. The light shielding cover 30 has two states: closed and open relative to the test area 10. In order to make the test result accurate, a first positioning mark is set on the surface of the test bottle 40, which is used to match the second positioning mark on the test slot 12 for positioning. When the light shielding cover 30 is opened, after the test bottle 40 is placed in the test slot 12, the positioning mark on the test bottle 40 is aligned with the mark of the test slot 12. When the elastic component 14 is not under force, the test bottle 40 extends out of the test slot 12, so that the staff can easily take out the test bottle 40. The light shielding cover 30 is closed, and the test bottle 40 is pressed by the light shielding cover 30, the elastic component 14 is compressed, and the test bottle 40 is pressed into the test slot 12, and the light shielding cover 30 and the elastic component 14 cooperate to stabilize the test bottle 40 between the light shielding cover 30 and the elastic component 14, thereby improving stability and making the measurement result more accurate. The detection unit adopts an infrared light detection module, which emits an infrared light source to penetrate the sample to be tested and project it onto the transmission light detector, and then outputs the detection result to the display screen through the built-in single chip microcomputer in the operation area 20.

[0027] Specifically, in one embodiment of the present application, the elastic component 14 is a spring, the elastic direction of the spring is consistent with the extension direction of the detection slot 12, the spring has a simple structure, is easy to install, and has low cost.

[0028] For example, Figure 2 As shown, a shock absorbing block 15 is provided at one end of the elastic component 14 close to the opening of the detection slot 12. The diameter of the shock absorbing block 15 is adapted to the diameter of the detection slot 12 so that the shock absorbing block 15 can slide up and down in the detection slot 12 along the extension direction of the detection slot 12. The shock absorbing block 15 is made of non-metallic material, such as rubber. When the detection bottle 40 is ejected, damage to the detection bottle 40 is avoided. When the light shielding cover 30 is closed, the stabilizing effect is better.

[0029] Specifically, a pressing block is provided on the side of the light shielding cover 30 facing the detection slot 12, and a groove 411 adapted to the shape of the pressing block is formed on the bottle cap 41 of the detection bottle 40, such as Figure 3 As shown, when the light shielding cover 30 is closed, the pressing block and the groove 411 cooperate to position, and a first positioning mark is provided on the detection bottle 40, which matches the second positioning mark on the detection area 10, so that when the detection bottle 40 is placed in the detection slot 12, the detection bottle 40 is positioned. In the embodiment of the present application, a positioning structure is provided between the bottle cap 41 and the light shielding cover 30 to prevent the detection bottle 40 from rotating in the detection slot 12 and affecting the detection effect.

[0030] For ease of use, the light shielding cover 30 is connected to the detection area 10 via a rotating shaft 32 , and the end of the light shielding cover 30 opposite to the rotating shaft 32 is connected to the detection area 10 via a bayonet structure 31 ; the rotating shaft 32 is arranged at the end of the light shielding cover 30 away from the detection slot 12 .

[0031] Furthermore, a torsion spring is provided on the rotating shaft 32 so that when the bayonet structure 31 is opened, the light shielding cover 30 automatically rotates to an open state.

[0032] Before the detection bottle 40 is inserted into the detection slot 12, the bottle body needs to be cleaned. In the embodiment of the present application, a cleaning ring 13 is provided at the opening of the detection slot 12. Figure 4 As shown, the inner diameter of the cleaning ring 13 is adapted to the outer diameter of the detection bottle 40 , and a sponge ring 131 is provided on the inner wall of the cleaning ring 13 . The sponge ring 131 fits the detection bottle 40 and is used to clean the outer wall of the detection bottle 40 when the detection bottle 40 is inserted into the detection slot 12 .

[0033] Specifically, a sealing strip 33 is provided on the edge of the light-shielding cover 30 facing the detection area 10, so that when the light-shielding cover 30 is closed, the detection area 10 is sealed. The sealing strip 33 is set in a sealing groove, and a convex plate is provided at the position of the detection area 10 relative to the sealing strip 33. The convex plate and the sealing strip 33 cooperate to seal the detection area 10.
