Description
Technical Field
[0001] The utility model relates to the technical field of water purifiers, in particular to a check valve with a high-pressure switch. Background Art
[0002] With the continuous improvement of living standards, many families are now very particular about water use. Many families use water purifiers. Water purifiers are very convenient to use. They can turn tap water into drinkable water. At the same time, they can filter out impurities, bacteria, heavy metals, etc. in the water. They have a better filtering effect on substances visible or invisible to the naked eye.
[0003] The existing water purifiers are assembled using a large number of parts, among which the high-pressure switch and the check valve are important components. However, the high-pressure switch and the check valve in the prior art are both single-piece settings, which results in a larger space occupied in the chassis of the water purifier and an increase in water connections, thereby increasing production costs. Utility Model Content
[0004] In order to solve the technical problems existing in the background technology, the utility model proposes a check valve with a high-pressure switch.
[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0006] A check valve with a high-pressure switch comprises a housing, a water passage and an installation cavity connected to the water passage are formed in the housing, a check component for controlling water on and off is arranged in the water passage, and a high-pressure switch for detecting and controlling the pressure at the water outlet of the water passage is arranged in the installation cavity;
[0007] The high-pressure switch includes a control component for receiving the outlet water pressure, and a driving component for driving the control component to operate, wherein the driving component includes a water sealing diaphragm for receiving the water pressure, and a jump diaphragm provided between the water sealing diaphragm and the control component;
[0008] When the water outlet area of the water passage is in a high-pressure state, the water-sealing diaphragm deforms and squeezes the jump diaphragm, so that the jump diaphragm pops up downward and abuts against the control component, and when the water outlet area of the water passage is in a low-pressure state, the jump diaphragm rebounds upward and releases the control component.
[0009] Preferably, the water passage includes a water inlet section and a water outlet section, the non-return assembly is arranged between the water inlet section and the water outlet section, and a water hole communicating with the installation cavity is formed in the water outlet section. Through the above improvement, the non-return assembly is arranged between the water inlet section and the water outlet section, and when the water pressure reaches a certain level, water can enter the water outlet section from the water inlet section, and part of the water can enter the installation cavity from the water hole to act on the high-pressure switch, so that the water pressure in the water outlet section can be detected, and the water pump and the whole machine can be controlled accordingly.
[0010] Preferably, the anti-return assembly includes a water-passing frame arranged in the water-passing channel, and a water-blocking block movably arranged on the water-passing frame, and an elastic element is arranged on the water-passing frame, one end of the elastic element abuts against the water-passing frame, and the other end abuts against the water-blocking block; when the anti-return assembly is in a water-closing state, the water-blocking block abuts against the water-passing frame to isolate the water inlet section and the water outlet section, and when the anti-return assembly is in a water-passing state, a certain water-passing gap is formed between the water-blocking block and the water-passing frame to connect the water inlet section and the water outlet section. Through the above improvements, when water starts to flow into the water inlet section, as the water pressure in the water inlet section increases, the water-blocking block is squeezed to form a water-passing gap between the water-blocking block and the water-passing frame, and water can enter the water-passing section from the water-passing gap. When the water inlet section stops flowing, the water pressure in the water inlet section decreases, and the water-blocking block abuts against the water-passing frame under the action of the elastic element, so that water cannot enter the water-passing section, thereby achieving an anti-return effect.
[0011] Preferably, the control assembly includes a mounting seat, a control board arranged on the mounting seat, a plug group arranged at the bottom of the control board, and a detection switch arranged on the control board, and a guide seat is arranged in the mounting cavity, and the driving end of the detection switch is placed in the guide seat. Through the above improvements, water enters the installation cavity from the water hole, which will push the water-sealing diaphragm, causing the water-sealing diaphragm to deform and push the jumping diaphragm downward. After the jumping diaphragm bears the pressure on its surface to a certain extent, it will enter an unstable state, and the diaphragm will instantly deform downward. During the downward process, it pushes the driving end of the detection switch below it to disconnect the detection switch. At this time, the corresponding pressure value is the disconnection value. When the water pump in the equipment stops, as the clean water in the pipeline is consumed, the water pressure in the pipeline will continue to drop. After dropping to a certain extent, when the pressure acting on the jumping diaphragm is less than the preset rebound force of the jumping diaphragm, the jumping diaphragm will enter an unstable state again, instantly rebound upward, and leave the detection switch below. The detection switch recovers after losing the external force and is reconnected. At this time, the corresponding pressure is the connection value. This reciprocating process realizes the control requirements of the water purifier.
[0012] Preferably, the control component includes a mounting seat, and an insert plate group inserted on the mounting seat, the insert plate group includes a first connecting plate and a second connecting plate, a first abutting plate is formed at the end of the first connecting plate, a second abutting plate is formed at the end of the second connecting plate, and a guide seat is arranged in the mounting cavity, and a driving block is slidably arranged in the guide seat; when the driving block abuts against the second abutting plate, the second abutting plate moves away from the second abutting plate, and when the driving block moves away from the first abutting plate, the second abutting plate fits with the first abutting plate. Through the above improvements, water enters the installation cavity from the water hole, which will push the water-sealing diaphragm, causing the water-sealing diaphragm to deform and push the jumping diaphragm downward. After the jumping diaphragm bears the pressure on its surface to a certain extent, it will enter an unstable state, and the diaphragm will instantly deform downward. During the downward process, it will push the driving block below it, so that the second abutment piece will move away from the first abutment piece. At this time, the corresponding pressure value is the disconnection value. When the water pump in the equipment stops, as the clean water in the pipeline is consumed, the water pressure in the pipeline will continue to decrease. After it drops to a certain extent, when the pressure acting on the jumping diaphragm is less than the preset rebound force of the jumping diaphragm, the jumping diaphragm will enter an unstable state again, instantly rebound upward, and leave the driving block below. After losing the external force, the second abutment piece will fit with the first abutment piece. At this time, the corresponding pressure is the connection value. The requirements for controlling the water purifier are met in this reciprocating manner.
[0013] Preferably, a groove is formed on the peripheral side of the guide seat, a waterproof ring is arranged in the groove, and the waterproof ring abuts against the inner wall of the installation cavity. Through the above improvements, the waterproof performance is improved.
[0014] Preferably, a sliding groove is formed on the guide seat for the control component to be placed in. Through the above improvements, the action end of the control component can slide in the sliding groove, thereby improving the smoothness during the control process.
[0015] Preferably, a slot for inserting the insert set is formed on the mounting seat, and the slot is sealed by glue injection. Through the above improvements, the waterproof performance is further improved.
[0016] Preferably, the top of the guide seat has an arc groove, and the jumping diaphragm fits with the arc groove when it pops up downward. Through the above improvement, when the jumping diaphragm pops up downward, it just fits with the arc groove, avoiding the loss of the jumping diaphragm and increasing the service life of the jumping diaphragm.
[0017] Preferably, quick connectors are provided at both ends of the water passage. Through the above improvements, the pipe body can be connected more quickly, greatly improving the assembly efficiency.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.
[0032] Embodiment 1
[0033] like Figure 1-4 As shown, a check valve with a high-pressure switch comprises a shell 1, a water passage 2 and an installation cavity 3 connected to the water passage 2 are formed in the shell 1, a check component 4 for controlling water flow is arranged in the water passage 2, and a high-pressure switch 5 for detecting the pressure at the water outlet end of the water passage 2 is arranged in the installation cavity 3.
[0034] Specifically, the high-pressure switch 5 includes a control component 101 for receiving the water pressure, and a driving component 102 for driving the control component 101 to work. The driving component 102 includes a water sealing diaphragm 103 for receiving the water pressure, and a jump diaphragm 104 provided between the water sealing diaphragm 103 and the control component 101.
[0035] When the water outlet area of the water passage 2 is in a high-pressure state, the water-sealing diaphragm 103 deforms and squeezes the jump diaphragm 104, so that the jump diaphragm 104 pops up downward and abuts against the control component 101, and when the water outlet area of the water passage 2 is in a low-pressure state, the jump diaphragm 104 rebounds upward and releases the control component 101.
[0036] A check assembly 4 is arranged in the water passage 2 of the shell 1 to control the flow of water, thereby playing the role of a check valve, and a high-pressure switch 5 is arranged in the installation cavity 3 to integrate the check valve and the high-pressure switch, thereby reducing the space consumption in the chassis of the water purifier, and can reduce the number of water connection ports, reduce the risk of water leakage of the equipment while alleviating assembly, and reduce the production cost. Compared with the traditional high-pressure switch, the jump diaphragm 104 is used to instantaneously trigger the high-pressure switch, thereby further improving the accuracy of water pressure control.
[0037] like Figure 3 , Figure 7As shown, a further explanation of the implementation method of the water passage 2 in this embodiment is provided, the water passage 2 includes a water inlet section 201 and a water outlet section 202, and the non-return component 4 is arranged between the water inlet section 201 and the water outlet section 202, the non-return component 4 can control water from the water inlet section 201 to enter the water outlet section 202, and a water hole 203 connected to the installation cavity 3 is formed in the water outlet section 202.
[0038] Since the check assembly 4 is arranged between the water inlet section 201 and the water outlet section 202, water can enter the water outlet section 202 from the water inlet section 201 when the water pressure reaches a certain level, and part of the water can enter the installation cavity 3 from the water hole 203 to act on the high-pressure switch 5, so that the high-pressure switch can detect the water pressure in the water outlet section 202 and make corresponding control on the water pump and the whole machine.
[0039] Specifically, the anti-return assembly 4 includes a water-passing frame 301 arranged in the water-passing channel 2, and a water-blocking block 302 movably arranged on the water-passing frame 301, and an elastic element 303 is arranged on the water-passing frame 301, one end of the elastic element 303 abuts against the water-passing frame 301, and the other end abuts against the water-blocking block 302;
[0040] Furthermore, when the anti-return component 4 is in a water-blocking state, the water retaining block 302 cannot be pushed open due to insufficient pressure in the water inlet section 201, so that the water retaining block 302 abuts against the water overflow rack 301 to isolate the water inlet section 201 and the water outlet section 202, and when the anti-return component 4 is in a water overflow state, a water overflow gap 304 is formed between the water retaining block 302 and the water overflow rack 301 to connect the water inlet section 201 and the water outlet section 202.
[0041] During the entire water flow process, when water starts to flow into the water inlet section 201, as the water pressure in the water inlet section 201 increases, the water retaining block 302 is squeezed, so that a water flow gap 304 is formed between the water retaining block 302 and the water flow frame 301, and water can enter the water flow section from the water flow gap 304. When the water inlet section 201 stops flowing, the water pressure in the water inlet section 201 decreases, and the water retaining block 302 will abut against the water flow frame 301 under the action of the elastic element 303, so that water cannot enter the water flow section, thereby achieving a backflow prevention effect.
[0042] like Figure 3 As shown, as a further explanation of the implementation method of the high-voltage switch 5 in this embodiment, the control component 101 includes a mounting seat 401, a control board 402 arranged on the mounting seat 401, a plug group 403 arranged at the bottom of the control board 402, and a detection switch 404 arranged on the control board 402, and a guide seat 105 is arranged in the mounting cavity 3, and the driving end 405 of the detection switch 404 is placed in the guide seat 105.
[0043] Specifically, during the operation of the water purifier, water enters the installation cavity 3 from the water hole 203, which pushes the water sealing diaphragm 103. The water sealing diaphragm 103 is deformed and pushes the jumping diaphragm 104 downward. After the jumping diaphragm 104 bears the pressure acting on its surface to a certain extent, it will enter an unstable state. The jumping diaphragm 104 will instantly deform downward. During the downward process, it pushes the driving end 405 of the detection switch 404 located below it, so that the detection switch 404 is disconnected. At this time, the corresponding pressure value is the disconnection value. When the water pump in the equipment stops, as the purified water in the pipeline is consumed, the water pressure in the pipeline will continue to decrease. After it drops to a certain extent, when the pressure acting on the jumping diaphragm 104 is less than the preset rebound force of the jumping diaphragm 104, the jumping diaphragm 104 will enter an unstable state again, instantly rebound upward, and leave the detection switch 404 below. The detection switch 404 recovers after losing the external force and is reconnected. At this time, the corresponding pressure is the connection value. This reciprocating process realizes the control requirements of the water purifier.
[0044] Furthermore, a sliding groove 603 is formed on the guide seat 105 for the driving end 405 of the detection switch 404 to be placed in, thereby improving the stability of the detection switch 404 during the driving process and improving the fluency during the control process.
[0045] Preferably, a groove 601 is formed on the peripheral side of the guide seat 105 , and a waterproof ring 602 is arranged in the groove 601 . The waterproof ring 602 abuts against the inner wall of the installation cavity 3 , thereby improving the waterproof performance.
[0046] like Figure 2 As shown, as an example, a slot 604 is formed on the mounting seat 401 for the insert set 403 to be placed in, and the slot 604 is filled with glue to further improve the waterproof performance.
[0047] like Figure 8 As shown, preferably, the top of the guide seat 105 has an arc groove 606 , and when the jumping diaphragm 104 pops up downward, it fits into the arc groove 606 , avoiding loss of the jumping diaphragm 104 and increasing the service life of the jumping diaphragm 104 .
[0048] like Figure 1 As shown, as a preference, quick connectors 605 are provided at both ends of the water passage 2, which can connect the pipe body more quickly and greatly improve the assembly efficiency.
[0049] Embodiment 2
[0050] like Figure 1 , Figure 5 , Figure 6As shown, the difference between this embodiment and the first embodiment is that the control component 101 includes a mounting seat 401, and a plug group 403 inserted on the mounting seat 401, the plug group 403 includes a first connecting piece 501 and a second connecting piece 502, a first abutting piece 503 is formed at the end of the first connecting piece 501, a second abutting piece 504 is formed at the end of the second connecting piece 502, and a guide seat 105 is arranged in the mounting cavity 3, and a driving block 505 is slidably arranged in the guide seat 105.
[0051] When the driving block 505 abuts against the second abutting piece 504 , the second abutting piece 504 moves away from the second abutting piece 504 , and when the driving block 505 moves away from the first abutting piece 503 , the second abutting piece 504 fits against the first abutting piece 503 .
[0052] Specifically, water enters the installation cavity 3 from the water hole 203, and pushes the water sealing diaphragm 103. The water sealing diaphragm 103 is deformed and pushes the jumping diaphragm 104 downward. After the jumping diaphragm 104 bears the pressure acting on its surface to a certain extent, it will enter an unstable state. The jumping diaphragm 104 will instantly deform downward. During the downward process, it pushes the driving block 505 located below it, so that the second abutment piece 504 is away from the first abutment piece 503. At this time, the corresponding pressure value is the disconnection value. When the water pump in the equipment is stopped, as the purified water in the pipeline is consumed, the pipeline water pressure will continue to decrease. After decreasing to a certain extent, when the pressure acting on the jumping diaphragm 104 is less than the preset rebound force of the jumping diaphragm 104, the jumping diaphragm 104 will enter an unstable state again, instantly rebound upward, and leave the driving block 505 below. After losing the external force, the second abutment piece 504 fits with the first abutment piece 503. At this time, the corresponding pressure is the connection value. This reciprocating process realizes the control requirements of the water purifier.
[0053] Furthermore, a sliding groove 603 for the driving block 505 to be placed in is formed on the guide seat 105, thereby improving the sliding stability of the driving block 505 and improving the smoothness during the control process.
[0054] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
