Description

Technical Field

[0001] The utility model belongs to the field of biological experimental equipment, and in particular relates to a water intake device used for animal experiments. Background Art

[0002] Animal laboratories used for biological research require the use of ultrapure water. The prior art has an ultrapure water machine, which has a water production structure, a water storage structure and a water outlet structure, and is controlled by physical or non-physical switches such as buttons, wheels, touch screens or pressure handles to complete water extraction.

[0003] During animal experiments, sterile gloves need to be worn on the hands. The gloves may be stained with animal body fluids and blood when taking and placing animals, dissecting, wiping, etc. during the research process. Even if a simple cleaning is performed, there will still be residues when touching the above-mentioned water dispensing switch, causing pollution to the water dispensing switch of the water purifier. In addition, as a local structure of the water purifier, it is difficult to centrally disinfect it. Therefore, a contactless water dispensing device is urgently needed. Utility Model Content

[0004] The purpose of the utility model is to provide a water intake device for animal experiments in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A water intake device for animal experiments, comprising a water outlet connected to a water source, a valve assembly arranged below the water outlet, and a base assembly located directly below the valve assembly, characterized in that the valve assembly comprises a valve body and a valve block rotatably arranged in the valve body, the valve block is driven by a driving structure, and the flow rate is adjusted by the opening;

[0007] Among them, the base assembly includes a fixed seat and a rotating seat, and the rotating seat has elastic components for resetting the rotating seat in both the forward and reverse rotation directions. A ring-shaped reflective mark is provided on the surface of the rotating seat. The valve assembly has a photoelectric sensor corresponding to the reflective mark, which is used to control the driving structure by measuring the rotation angle of the rotating seat to adjust the opening of the valve block.

[0008] As a further optimization scheme of the utility model, the valve body is provided with two upper and lower chambers, the upper chamber is connected with the water outlet device, and the lower chamber is connected with the outflow port arranged at the bottom of the valve body. The upper chamber is provided to accommodate the valve block, and the lower chamber is used for water flow aggregation.

[0009] As a further optimization solution of the utility model, a protective cover to prevent sputtering pollution is arranged outside the outflow port.

[0010] As a further optimization scheme of the utility model, the valve block is located in the upper chamber, the valve block is provided with a vertically oriented rotating shaft, the surface of the valve block is provided with an arc-shaped through groove, and the surface between the upper chamber and the lower chamber is provided with an opening groove, the opening groove and the through groove have the same arc and are on the same circle, the opening is adjusted by the overlap, the valve block is rotated to make the through groove overlap with the opening groove, and water is taken in, and the opening size is controlled by the rotation angle, thereby controlling the water intake flow rate.

[0011] As a further optimization scheme of the utility model, a slow flow hole is also provided on the surface between the upper chamber and the lower chamber, which is used to accurately draw water from the tracking groove. The slow flow hole includes a plurality of through holes with gradually changing apertures and are distributed in an arc shape. The slow flow hole is used to reduce the water flow speed. When the through groove is aligned with the slow flow hole, the water flows out slowly to facilitate the need for accurate water drawing in small amounts. It should be noted that since the lower chamber has a certain accommodating space, when it flows empty, it may take a certain amount of time for the slow flow hole to enter the outflow port from the lower chamber when discharging water, causing a delay, and the outflow amount is difficult to control. For this reason, the lower chamber can be divided into two sections, and an outflow port is set for each section. The outflow port corresponding to the slow flow hole is set to a small glue nozzle, which will not flow back air. Then the water in the corresponding lower chamber is always full of water and will not flow empty, thereby solving the problems of outflow delay and difficult to control outflow amount.

[0012] As a further optimization scheme of the utility model, the driving structure is a contactless driving device, which includes a ring rotatably mounted on the outside of the valve body, at least one electromagnet is arranged on the surface of the ring, a gear ring is arranged on the surface of the ring, and the ring is driven by a motor and a gear, and an attraction member corresponding to the electromagnet is arranged in the valve body. Through the contactless driving method, the shaft of the valve block is prevented from being connected to the outside, which can effectively prevent the valve block from being contaminated by the shaft sealing problem.

[0013] As a further optimization solution of the utility model, a flange supporting the collar is also provided on the periphery of the valve body.

[0014] The beneficial effects of the utility model are:

[0015] The utility model places a water collection container on a rotating seat and applies pressure to rotate it. The photoelectric sensor detects a change in the reflective mark, that is, detects the rotation angle through the change, and then controls the valve block to rotate the corresponding angle to adjust the opening. When no water is collected, the container is manually rotated back to the initial position, or the elastic component of the rotating seat is automatically reset to control the valve block to rotate to close. When the part touched by the gloves needs to be cleaned and disinfected, only the container needs to be cleaned, and the parts on the valve assembly will not be touched.

DETAILED DESCRIPTION

[0022] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-5 As shown, a water intake device for animal experiments includes a water outlet device 1 connected to a water source, a valve assembly 2 arranged below the water outlet device 1, and a base assembly 3 located directly below the valve assembly 2, characterized in that: the valve assembly 2 includes a valve body 21 and a valve block 27 rotatably arranged in the valve body 21, and the valve block 27 is driven by a driving structure to adjust the flow rate by opening;

[0025] Among them, the base assembly 3 includes a fixed seat 31 and a rotating seat 32, and the rotating seat 32 has elastic components for resetting the rotating seat 32 in both positive and negative rotation directions. A ring-shaped reflective mark 33 is provided on the surface of the rotating seat 32. The valve assembly 2 has a photoelectric sensor 213 corresponding to the reflective mark 33, which is used to control the driving structure by measuring the rotation angle of the rotating seat 32 to adjust the opening of the valve block 27.

[0026] The valve body 21 is provided with two upper and lower chambers, the upper chamber is connected with the water outlet device 1, and the lower chamber is connected with the outflow port 212 arranged at the bottom of the valve body 21. The upper chamber is provided to accommodate the valve block 27, and the lower chamber is used for water flow aggregation. A protective cover is provided outside the outflow port 212 to prevent splashing pollution.

[0027] The valve block 27 is located in the upper chamber. The valve block 27 is provided with a vertical rotating shaft. An arc-shaped through groove 211 is opened on the surface of the valve block 27. An opening groove 210 is opened through the surface between the upper chamber and the lower chamber. The arc of the opening groove 210 and the through groove 211 are the same, and they are on the same circle. The opening is adjusted by the overlap. The valve block 27 is rotated to make the through groove 211 overlap with the opening groove 210 to draw water. The opening size is controlled by the rotation angle, thereby controlling the water intake flow rate.

[0028] A slow flow hole 29 is also provided on the surface between the upper chamber and the lower chamber, which is used to accurately draw water from the tracking groove 211. The slow flow hole 29 includes a plurality of through holes with gradually changing apertures and are distributed in an arc shape. The slow flow hole 29 is used to reduce the water flow speed. When the through groove 211 is aligned with the slow flow hole 29, it can be adjusted through a plurality of diffuse flow holes 29 to facilitate the need for accurate water extraction in small amounts.

[0029] It should be noted that, since the lower chamber has a certain amount of accommodating space, when it is emptied, it may take a certain amount of time for the slow flow hole 29 to enter the outflow outlet 212 from the lower chamber when discharging water, causing a delay and making it difficult to control the outflow amount. For this reason, the lower chamber can be divided into two sections (not shown in the figure), and an outflow outlet 212 is set for each section. The outflow outlet 212 corresponding to the slow flow hole 29 is set to a small glue nozzle that will not flow back air. In this way, the water in the corresponding lower chamber is always full of water and will not flow empty, thereby solving the problems of outflow delay and difficulty in controlling the outflow amount.

[0030] The driving structure is a contactless driving device, which includes a ring 22 rotatably mounted on the outside of the valve body 21, at least one electromagnet 26 is arranged on the surface of the ring 22, a gear ring 25 is arranged on the surface of the ring 22, and the ring 22 is driven by a motor 23 and a gear, an attraction member 28 corresponding to the electromagnet 26 is arranged in the valve body 21, and a flange 24 supporting the ring 22 is also arranged on the periphery of the valve body 21. The contactless driving method avoids the shaft of the valve block 27 from being connected to the outside, which can effectively prevent the valve block from being contaminated by the shaft sealing problem.

[0031] The specific implementation method is as follows: by placing the water collection container on the rotating seat 32 and applying pressure to rotate it, the photoelectric sensor 213 detects that the reflective mark 33 changes, that is, the rotation angle is detected by the change. The photoelectric sensor 213 detects the direction and amount of angle change according to the reflective mark 33, which is a prior art. Then the valve block 27 is controlled to rotate to the corresponding angle and direction, and the fast or slow water discharge is determined according to the reverse rotation, and the flow rate can be adjusted according to the rotation amount. When no water is taken, the container is manually rotated back to the initial position, or automatically reset by the elastic component of the rotating seat 32, so as to control the valve block 27 to rotate to close. When the part touched by the gloves needs to be cleaned and disinfected, only the container needs to be cleaned, and the parts on the valve assembly 2 will not be touched.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
