[0041] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In the description of this application, it should be noted that the terminology used herein is only for describing specific implementations and is not intended to limit the exemplary implementations according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1

[0042] This embodiment provides a chemical reagent dilution device, including:

[0043] Main pipe 1, one end of which is sealed;

[0044] Branch pipe 2 is fixedly installed on the outside of main pipe 1, and a venturi tube 3 is fixedly installed at the other end of branch pipe 2;

[0045] The valve body 4 is fixedly mounted on the main pipe 1. The valve body 4 has an inner cavity 5. The main pipe 1 has a connecting hole 6 that communicates with the inner cavity 5. The liquid inlet 7 of the branch pipe 2 is connected to the inner cavity 5.

[0046] Valve core 8, the upper end of which is used to block the liquid inlet 7 of branch pipe 2;

[0047] Iron core 9 is vertically movable inside valve body 4, with the upper end of iron core 9 abutting against the lower end of valve core 8;

[0048] The movable cylinder 10 is fixedly installed on the outside of the valve body 4, and magnets 11 are movably sleeved on the outer ring of the movable cylinder 10.

[0049] The elastic component is used to provide an upward force to the iron core 9.

[0050] The inner wall of the movable cylinder 10 is connected to the inner cavity 5 of the valve core 8, and the iron core 9 is movably disposed inside the movable cylinder 10. The movable cylinder 10 provides guidance and installation space for the up-and-down movement of the iron core 9.

[0051] In this technical solution, during actual use, two containers are also provided on the outside. The first container contains water, and the second container contains chemical agents. The Venturi tube 3 has a throat. The throat of the Venturi tube 3 is connected to the second container through a pipeline. The first container is connected to the main pipe 1 through a pipeline. A water pump is provided on the pipeline between the first container and the main pipe 1.

[0052] The main pipe 1 is used to transport water from the first container, and one end of it is sealed to ensure that the water flows towards the branch pipe 2. The branch pipe 2 connects the main pipe 1 and the venturi pipe 3, and is the channel through which the water flows into the venturi pipe 3.

[0053] The valve body 4 is connected to the main pipe 1 through the inner cavity 5 and the connecting hole 6. The valve core 8 controls the opening and closing of the liquid inlet 7 of the branch pipe 2 under the action of the iron core 9.

[0054] Since the magnet 11 is movably mounted on the movable cylinder 10, when it needs to be opened, the magnet 11 is moved upward. When the magnet 11 moves upward, the iron core 9 will move downward due to magnetic force.

[0055] After the iron core 9 moves downward, it no longer abuts against the lower end of the valve core 8, allowing the valve core 8 to move downward due to liquid pressure, creating a gap with the inlet 7 of the branch pipe 2. Water can enter the branch pipe 2 through this gap. When the water flows into the venturi tube 3 along the branch pipe 2, a negative pressure will be generated at the throat of the venturi tube 3, thereby drawing the chemical agent in the second container into the venturi tube 3 through the throat for mixing and discharge.

[0056] Meanwhile, since the upward movement of magnet 11 requires manual support, after mixing is complete, magnet 11 can fall due to its own weight, which also causes magnet 11 to release the magnetic attraction connection with iron core 9. Then, iron core 9 will move upward due to the elasticity of the elastic component and come into contact with the lower end of valve core 8, causing valve core 8 to re-seal the liquid inlet 7 and stop the water flow into branch pipe 2.

[0057] With this structural design, the valve is opened and closed by the magnet 11. At the same time, the valve needs to be manually held when it is open. After the external force is lost, the magnet 11 will release the magnetic connection to the iron core 9, thereby automatically closing the valve and avoiding the situation of forgetting to close the valve. Example 2

[0058] This embodiment provides a chemical reagent dilution device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] Furthermore, a chemical reagent dilution device is characterized in that the elastic component comprises:

[0060] Spring 12 is located inside the movable cylinder 10;

[0061] The upper end of the spring 12 is in contact with the lower end of the iron core 9, and the lower end of the spring 12 is in contact with the bottom of the movable cylinder 10.

[0062] In this technical solution, the spring 12 is in a compressed state, always applying an upward force to the iron core 9. When the downward magnetic attraction force of the magnet 11 on the iron core 9 disappears, the elastic force of the spring 12 pushes the iron core 9 upward, thereby driving the valve core 8 to move upward to block the liquid inlet 7 of the branch pipe 2.

[0063] Through this structural design, the elastic force of the spring 12 is used to realize the automatic reset of the iron core 9 and the valve core 8, ensuring the effective sealing of the liquid inlet 7 of the branch pipe 2 in the non-working state. The structure is simple and the reset is reliable. Example 3

[0064] This embodiment provides a chemical reagent dilution device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] Furthermore, it also includes:

[0066] The tray 13, the magnet 11 is fixedly mounted on the tray 13, and both the tray 13 and the magnet 11 are movably sleeved on the outside of the movable cylinder 10;

[0067] A limiting block 14 is fixedly installed at the lower end of the movable cylinder 10, and the upper end of the limiting block 14 abuts against the lower end of the magnet 11.

[0068] Elastic element 15, the elastic element 15 is sleeved on the movable cylinder 10, the upper end of the elastic element 15 abuts against the valve body 4, and the lower end of the elastic element 15 abuts against the upper end of the magnet 11.

[0069] In this technical solution, the support plate 13 is used to mount the magnet 11, and the elastic element 15 applies a downward force to the magnet 11, so that the magnet 11 is in contact with the limiting block 14 under normal conditions. When it is necessary to drive the iron core 9 to move downward, the support plate 13 drives the magnet 11 to move upward through external force. At this time, the magnetic force generated by the magnet 11 attracts the iron core 9 to move downward, overcoming the elastic force of the spring 12 in the elastic component.

[0070] This structural design utilizes magnetic force to achieve non-contact driving of the iron core 9, avoiding wear caused by mechanical contact. At the same time, in conjunction with the elastic element 15 and the limiting block 14, it ensures the reset and position restriction of the magnet 11, improving service life and stability. Example 4

[0071] This embodiment provides a chemical reagent dilution device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] Furthermore, it also includes:

[0073] Guide posts 16 are fixedly installed at the lower end of branch pipe 2, and at least two guide posts 16 are provided;

[0074] Guide sleeve 17, which is fixedly provided on the support plate 13 to match the guide post 16.

[0075] In this technical solution, the guide post 16 and the guide sleeve 17 cooperate with each other. When the support plate 13 drives the magnet 11 to move up and down, the guide sleeve 17 slides along the guide post 16 to provide guidance for the movement of the support plate 13 and the magnet 11.

[0076] This structural design ensures the smoothness and accuracy of the up-and-down movement of the tray 13 and the magnet 11, preventing them from shifting or shaking during movement, and ensuring that the magnetic force of the magnet 11 on the iron core 9 is stable and reliable. Example 5

[0077] This embodiment provides a chemical reagent dilution device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0078] Furthermore, it also includes:

[0079] The pressing part 18 is formed by bending one end of the tray 13 downward.

[0080] In this technical solution, the pressing part 18 provides the operator with a force application point. When it is necessary to manually control the drive component, the operator can press the pressing part 18 to make the tray 13 drive the magnet 11 to move upward.

[0081] This structural design increases the ease of operation of the device, enabling manual operation in special circumstances and improving the device's applicability. Example 6

[0082] This embodiment provides a chemical reagent dilution device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0083] Furthermore, the valve core 8 is a diaphragm, and the valve core 8 is provided with a damping hole 19 and a pilot hole 20. The iron core 9 blocks the pilot hole 20 under normal conditions. The pilot hole 20 is connected to the liquid inlet 7 of the branch pipe 2, and the damping hole 19 is connected to the connecting hole 6.

[0084] In this technical solution, the valve core 8 adopts a diaphragm structure, which has a certain degree of elasticity and sealing performance. Under normal conditions, the iron core 9 blocks the pilot hole 20, and the water in the main pipe 1 enters the lower part of the valve core 8 through the connecting hole 6 and the damping hole 19, which increases the pressure at the lower end of the valve core 8 and tightly seals the liquid inlet 7 of the branch pipe 2.

[0085] When the iron core 9 moves downward and no longer blocks the pilot hole 20, the water below the valve core 8 flows into the branch pipe 2 through the pilot hole 20. The pressure at the lower end of the valve core 8 decreases, and under the action of the water pressure at the upper end, it moves downward and opens the liquid inlet 7 of the branch pipe 2.

[0086] Through this structural design, the valve core 8 is precisely controlled by the cooperation of the damping hole 19 and the pilot hole 20, which improves the sensitivity and reliability of opening and closing the liquid inlet 7 of the branch pipe 2. Example 7

[0087] This embodiment provides a chemical reagent dilution device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0088] Furthermore, it also includes:

[0089] The sealing head 21 is fixedly installed at the upper end of the iron core 9 and is used to seal the pilot hole 20;

[0090] The sealing head 21 has a certain degree of elasticity.

[0091] In this technical solution, the plugging head 21 is made of elastic material. When the iron core 9 moves upward, the plugging head 21 can fit tightly against the pilot hole 20 to ensure effective sealing of the pilot hole 20. When the iron core 9 moves downward, the plugging head 21 separates from the pilot hole 20 without affecting the liquid flow.

[0092] This structural design enhances the sealing performance of the pilot hole 20, preventing liquid leakage from affecting the control effect of the valve core 8. At the same time, the properties of the elastic material reduce wear between the plug head 21 and the valve core 8, extending the service life of the components.

[0093] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features described in this application specification can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
