Description

Technical Field

[0001] The invention relates to the technical field of fluid conveying equipment, and in particular to a microbubble water pump. Background Art

[0002] Research has found that during the generation of microbubble water, microscopic water molecules and oxygen anions that are beneficial to the body can be split, and combined with visual and tactile sensations, they can produce the best soothing effect on the user's body and mind. Therefore, the method of generating microbubble water has become an important topic in related industries.

[0003] A good microbubble water generator must be able to produce the finest water bubbles in the most efficient process to meet the needs of modern people. In traditional microbubble water generators, gas and water are mixed in a mixing tank and then discharged from the faucet to form microbubble water. However, the current equipment cannot control the ratio of water volume to gas volume well, resulting in poor quality of microbubble water. Summary of the invention

[0004] The object of the present invention is to provide a microbubble water pump for effectively controlling the regulation of water flow and air flow, ensuring an optimal water-gas mixing ratio, and making the final microbubble water of better quality.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] A microbubble water pump comprises a pump head body and a side cover. A water inlet chamber, a source water chamber and a high-pressure chamber are arranged in the pump head body. The water inlet chamber and the high-pressure chamber are connected with a water inlet and a water outlet respectively. An air inlet connected with the source water chamber is arranged on the side cover. Water in the source water chamber enters the high-pressure chamber after being pressurized. The pump also comprises a flow control component and an air control component. A vacuum chamber is formed between the flow control component and the pump head body. A first flow channel is also arranged in the pump head body. The vacuum chamber is connected with the source water chamber through the first flow channel. A water sealing ring and a flow control component for controlling the sealing or conduction of the water channel at the water sealing ring are formed in the water channel connecting the water inlet chamber and the vacuum chamber. An air sealing ring and an air control component for controlling the sealing or conduction of the air channel at the air sealing ring are formed in the air channel connecting the vacuum chamber and the air inlet.

[0007] Some related components of existing water pumps only have the function of cutting off the water flow, and do not have the function of adjusting the output flow and air intake under the condition of pressurized water source. In this scheme, a flow control component is arranged in the pump head body, a vacuum chamber is formed between the flow control component and the pump head body, and an air control component is arranged between the vacuum chamber and the air inlet. When the microbubble water pump is not working, the flow control component controls the water path sealing at the water sealing ring, and the air control component controls the air path sealing at the rear end of the air inlet; when the microbubble water pump is working, the water flow or air in the vacuum chamber is sucked away to form a certain vacuum degree. At this time, the flow control component controls the water path sealing at the water sealing ring. The air control component controls the conduction of the air path between the air inlet and the vacuum chamber, and the water flow rate and the air flow rate after conduction are related to the vacuum degree in the vacuum chamber. The higher the vacuum degree, the greater the flow rate after conduction, and the smaller the vacuum degree, the smaller the flow rate after conduction. By adjusting the working voltage (power) of the microbubble water pump, the vacuum degree in the vacuum chamber when the microbubble water pump is working can be adjusted. Therefore, the structural design of this scheme is adopted, and the water flow rate and air intake of the microbubble water pump can be adjusted by adjusting the working voltage (power) of the microbubble water pump, so that the ratio of the two is optimal and the quality of microbubble water is better.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example 1

[0022] A microbubble water pump, comprising a pump head body 25 and a side cover 39, wherein the pump head body 25 is provided with a water inlet chamber 03, a source water chamber 23, and a high-pressure chamber 24, wherein the water inlet chamber 03 and the high-pressure chamber 24 are connected to a water inlet 01 and a water outlet 16 respectively, and the side cover 39 is provided with an air inlet 38 connected to the source water chamber 23, and the water in the source water chamber 23 is pressurized and enters the high-pressure chamber 24, and further comprising a flow control component and an air control component, wherein a flow control component and a main body of the pump head body 25 are formed between the flow control component and the main body of the pump head body 25. A vacuum chamber 05 is formed, and a first flow channel 27 is also provided in the pump head body 25. The vacuum chamber 05 is connected with the source water chamber 23 through the first flow channel 27. A water sealing ring 14 and a flow control component for controlling the sealing or conduction of the water path at the water sealing ring 14 are formed on the water path connecting the water inlet chamber 03 and the vacuum chamber 05. An air sealing ring 49 and an air control component for controlling the sealing or conduction of the air path at the air sealing ring 49 are formed on the air path connecting the vacuum chamber 05 and the air inlet 38.

[0023] like Figure 1 and 2 As shown, this embodiment is applicable to microbubble water pumps with pressurized and non-pressurized water sources. When the microbubble water pump is not working, the flow control component controls the water circuit sealing at the water sealing ring 14, and the air control component controls the air circuit sealing at the rear end of the air inlet 38; when the microbubble water pump is working, the water flow or air in the vacuum chamber 05 is sucked away to form a certain vacuum degree. At this time, the flow control component controls the water circuit conduction at the water sealing ring 14, and the air control component controls the air circuit conduction between the air inlet 38 and the vacuum chamber 05. The water flow rate and air flow rate after conduction are related to the vacuum degree in the vacuum chamber 05. The higher the vacuum degree, the greater the flow rate after conduction, and the smaller the vacuum degree, the smaller the flow rate after conduction. Adjusting the working voltage (power) of the microbubble water pump can adjust the vacuum degree in the vacuum chamber 05 when the microbubble water pump is working. Therefore, the structural design of this scheme is adopted, and the water flow rate and air intake of the microbubble water pump can be adjusted by adjusting the working voltage (power) of the microbubble water pump, so that the ratio of the two is optimal and the quality of microbubble water is better.

[0024] Example 2

[0025] The flow control component includes a control rod 15, a first pressure-sensitive diaphragm 06, a first spring 12, a diaphragm pressure plate 50, and a fastening connecting rod 13. The first pressure-sensitive diaphragm 06 is sealed and fixed between the pump cover 07 and the pump head body 25. The first pressure-sensitive diaphragm 06 and the pump cover 07 form an atmospheric cavity 09, and the pump cover 07 is provided with an atmospheric hole 08. The middle part of the first pressure-sensitive diaphragm 06 is pressed against the pressure plate 10 at the top of the control rod 15 through the diaphragm pressure plate 50. A flow limiting groove 11 is provided on the side of the control rod 15. The water sealing ring 14 is formed by the control rod 15 body and is located below the flow limiting groove 11. The water sealing ring 14 is sealed by the water sealing pad 04. The lower end of the control rod 15 is connected to the second pressure-sensitive diaphragm 19, and an external pressure piece is provided in the high-pressure cavity 24. 18, the external pressure piece 18 is provided with a slide groove 21 with an opening facing upward, the bottom surface of the second pressure-sensitive diaphragm 19 is circumferentially sealed and pressed between the external pressure piece 18 and the pump head body 25, the lower end of the fastening connecting rod 13 passes through the diaphragm pressure plate 50, the first pressure-sensitive diaphragm 06, the control rod 15 and the second pressure-sensitive diaphragm 19 and extends into the slide groove 21, the lower end of the fastening connecting rod 13 is provided with an internal pressure piece 22 and a nut 20 for pressing the second pressure-sensitive diaphragm 19, one end of the first spring 12 acts on the control rod 15, and the other end acts on the inner wall of the vacuum chamber 05, the control rod 15 controls the sealing or conduction of the water path between the water inlet chamber 03 and the vacuum chamber 05 under the joint action of the pressure in the atmospheric chamber 09, the pressure in the vacuum chamber 05 and the first spring 12.

[0026] The specific working principle of the flow control component of this embodiment is as follows:

[0027] like Figure 1As shown, when the microbubble water pump is not working, the sum of the forces acting on the first pressure-sensitive diaphragm 06 by the pressure in the vacuum chamber 05 and the elastic force of the first spring 12 is greater than the force acting on the first pressure-sensitive diaphragm 06 by the air pressure in the atmospheric chamber 09, and the control rod 15 seals the water-sealing ring 14 under the joint action of the above forces; when the microbubble water pump is working, the water flow or air in the vacuum chamber 05 is sucked away to form a certain vacuum degree. At this time, the sum of the forces acting on the first pressure-sensitive diaphragm 06 by the pressure in the vacuum chamber 05 and the elastic force of the first spring 12 is less than the force acting on the first pressure-sensitive diaphragm 06 by the air pressure in the atmospheric chamber 09, and the control rod 15 moves downward (in the direction of the water inlet chamber 03) under the joint action of the above forces, and the side wall of the control rod 15 is provided with a flow-limiting groove 11 which refers to the control of the lower end of the water-sealing ring 14. There is no flow limiting groove on the rod 15. A flow limiting groove 11 is provided on the side wall of the control rod 15 above the water sealing ring 14. The control rod 15 moves downward so that the water sealing ring 14 is just separated from the water sealing pad 04. When it continues to move downward, the water inlet chamber 03 is connected with the vacuum chamber 05 through the flow limiting groove 11. When the flow limiting groove 11 of the control rod 15 just moves downward to the water inlet chamber 03, the flow channel connecting the water inlet chamber 03 with the vacuum chamber 05 through the flow limiting groove 11 is smaller, and the flow rate pumped out by the microbubble water pump will be smaller. If the control rod 15 continues to move downward, the part of the control rod 15 with the flow limiting groove 11 moves downward to a longer distance into the water inlet chamber 03, then the flow channel area connecting the water inlet chamber 03 with the vacuum chamber 05 through the flow limiting groove 11 will increase, and the flow rate pumped out by the microbubble water pump will increase. Therefore, by adjusting the working voltage (power) of the microbubble water pump, the vacuum size in the vacuum chamber 05 can be adjusted, and then the downward movement distance of the control rod 15 can be adjusted, thereby playing the function of adjusting the output flow of the microbubble water pump.

[0028] Example 3

[0029] like Figure 1 As shown, a bracket 17 is provided in the water inlet chamber 03, and a water inlet channel 02 connecting the water inlet 01 and the water inlet chamber 03 is provided on the bracket 17. The lower end of the bracket 17 is used to press the top surface of the second pressure-sensitive diaphragm 19 circumferentially, and the top end of the bracket 17 presses the water sealing pad 04 of the sealing water sealing ring 14.

[0030] Example 4

[0031] The air control assembly includes a second spring 28, a third pressure-sensitive diaphragm 30, and an adjusting block 33. The side cover 39 is provided with an adjusting hole 37 that is connected to the air inlet 38. The adjusting hole 37 is large at the upper end and short at the lower end, and is set in a conical shape. The side cover 39 is provided with an adjusting cavity 32 for installing the adjusting block 33. The upper end of the adjusting block 33 is threadedly sealed with the adjusting cavity 32, and its lower end matches the adjusting hole 37. An air passage cavity 36 is formed between the adjusting block 33 and the adjusting cavity 32. The peripheral seal of the third pressure-sensitive diaphragm 30 is tightly pressed between the side cover 39 and the pump head body 25. One end of the second spring 28 acts on the third pressure-sensitive diaphragm 30. , and the other end acts on the pump head body 25. The third pressure-sensitive diaphragm 30 is provided with a first air hole 34. The first air hole 34 and the vacuum chamber 05 are communicated through the second air hole 29. An air cavity 48 is formed between the third pressure-sensitive diaphragm 30 and the side cover 39. A sealing ring 49 for sealing the air path between the first air hole 34 and the air cavity 48 is provided on the side cover 39. The air cavity 48 is communicated with the air cavity 36 through the third air hole 35. The third pressure-sensitive diaphragm 30 controls the sealing or conduction of the air path at the sealing ring 49 under the joint action of the pressure in the vacuum chamber 05, the pressure in the air cavity 48 and the second spring 28.

[0032] The specific working principle of the gas control component in this embodiment is as follows:

[0033] like Figure 2 As shown, when the microbubble water pump is not working, the sum of the forces acting on the third pressure-sensitive diaphragm 30 by the pressure in the vacuum chamber 05 and the elastic force of the second spring 28 is greater than the force acting on the third pressure-sensitive diaphragm 30 by the air pressure in the air chamber 48, and the third pressure-sensitive diaphragm 30 seals the air-sealing ring 49 under the combined action of the above forces; when the microbubble water pump is working, the water or air in the vacuum chamber 05 is sucked away to form a certain vacuum degree, and the vacuum chamber 05 is connected to the second air hole 29. At this time, the sum of the forces acting on the third pressure-sensitive diaphragm 30 by the pressure in the vacuum chamber 05 and the elastic force of the second spring 28 is less than the force acting on the third pressure-sensitive diaphragm 30 by the air pressure in the air chamber 48, and the pressure in the air chamber 48 acts on the third pressure-sensitive diaphragm 30 to compress the second spring 28, so that the air-sealing ring 49 is sealed. The air path at the collar 19 is open, and external air enters the vacuum chamber 05 through the first air hole 34. Since the adjustment hole 37 is in a conical shape with a larger top and a smaller bottom, the lower end of the adjustment block 33 matches the shape of the adjustment hole 37, and the adjustment block 33 is threadedly connected to the adjustment chamber 32. When the adjustment block 33 is rotated to move it upward, more air enters the air chamber 36 through the adjustment hole 37, and vice versa. This can effectively control the amount of gas entering the vacuum chamber 05 and mixing with the source water. The greater the vacuum degree of the vacuum chamber 05, the greater the degree of compression of the second spring 28, and the greater the air intake. If the water pressure in the vacuum chamber 05 is too high, the third pressure-sensitive diaphragm 30 will be squeezed to the right to seal the air-sealing collar 49, thereby ensuring that water will not flow out of the air inlet 38.

[0034] Example 5

[0035] The microbubble water pump also includes a pressure relief component, which includes a fourth pressure-sensitive diaphragm 44, a third spring 42, and a threaded rod 40. The fourth pressure-sensitive diaphragm 44 is sealed and pressed between the lower end of the side cover 39 and the pump head body 25. The side cover 39 body is provided with a compression chamber, and a left convex plate 43 and a right convex plate 41 are oppositely arranged in the compression chamber. One end of the third spring 42 acts on the right convex plate 41, and the other end acts on the left convex plate 43 and presses the fourth pressure-sensitive diaphragm 44 through the left convex plate 43. The convexities on the two convex plates are used to press the third spring 42. The spring 42 is used for limiting to prevent the third spring 42 from being displaced during compression and affecting the working stability of the pressure relief assembly. The threaded rod 40 passes horizontally through the side cover 39 and is connected to the side of the right convex plate 41. The pump head body 25 is provided with a second flow channel 46 and a third flow channel 47. The third flow channel 47 is connected to the high-pressure chamber 24. The second flow channel 46 is provided with a water sealing port 45 formed by the pump head body 25. The water path between the water sealing port 45 and the third flow channel 47 is sealed or connected through the fourth pressure-sensitive diaphragm 44 and the third spring 42.

[0036] The specific working principle of the pressure relief assembly of this embodiment is as follows:

[0037] like Figure 2 As shown, when the water pressure in the high-pressure chamber 24 is too high, the internal water pressure squeezes the fourth pressure-sensitive diaphragm 44 to the right and compresses the third spring 42, so that the water path at the water sealing port 45 is open, and the water in the high-pressure chamber 24 enters the second flow channel 46 through the third flow channel 47, and then enters the source water chamber 23, forming a reflux pressure relief effect, maintaining a stable working pressure inside the pump head body 25. By adjusting the contact length between the threaded rod 40 and the side cover 39, the compression degree of the third spring 42 can be adjusted, thereby adjusting the water pressure required for the water flow in the high-pressure chamber 24 to overcome the reaction force of the third spring 42, thereby realizing the water pressure regulation effect in the high-pressure chamber 24.

[0038] Specifically, the high pressure chamber 24 is surrounded by a collar 26 formed by the main body of the pump head body 25 .
