Description

Technical Field

[0002] Smart toilets are a hot topic in the bathroom industry. They replace toilet paper with water, triggering a bathroom revolution. Technology, convenience, and hygiene are the future trends of bathroom development. Smart toilets have a flushing valve structure for flushing. The flushing valve structure usually has a water inlet and two water outlets. The two water outlets are connected to the siphon port and the side flush port, respectively, to supply water to the siphon port and the side flush port.

[0003] The water in the flush valve structure is supplied by an external water pipe, so the water pressure in the flush valve structure will be affected by the water pressure in the external water pipe.

[0043] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0044] like Figure 1 As shown, the embodiment of the present application provides a liquid valve device 100, which is used to control the flow direction and on-off of liquid. It is understandable that the liquid valve device 100 can also be used for fluids such as gas, solid-liquid mixture, etc., and the present application takes liquid as an example for description.

[0045] like Figures 1 to 3 As shown, the liquid valve device 100 includes a first housing 1, a valve core 2, a second housing 3, a driving assembly 4, a pressure relief assembly 5, a liquid inlet pipe 6, a first clamp 7, a liquid outlet pipe 8 and a second clamp 9. The first housing 1 is provided with a valve cavity 11, and the second housing 3, the pressure relief assembly 5, the liquid inlet pipe 6 and the liquid outlet pipe 8 are all connected to the valve cavity 11. The valve core 2 is movably arranged in the valve cavity 11, and the driving assembly 4 is used to drive the valve core 2 to move in the valve cavity 11 to control the liquid in the liquid inlet pipe 6 to flow into the second housing 3 or the liquid outlet pipe 8, so as to control the flow direction of the fluid. The pressure relief assembly 5 is used for depressurizing the valve cavity 11. The first clamp 7 is used to detachably connect the liquid inlet pipe 6 to the first housing 1, and the second clamp 9 is used to detachably connect the liquid outlet pipe 8 to the first housing 1.

[0046] For the first housing 1, Figures 1 to 3 As shown, the first housing 1 is roughly in the shape of a circular tube, and the cylindrical cavity in the first housing 1 is a valve cavity 11. The first housing 1 is provided with a first liquid inlet pipe 12 and a pressure relief pipe 13 on opposite sides along the diameter direction, and the first housing 1 is provided with a first liquid outlet pipe 14 and a second liquid outlet pipe 15 on opposite ends along the axial direction, and the first liquid inlet pipe 12, the pressure relief pipe 13, the first liquid outlet pipe 14 and the second liquid outlet pipe 15 are all connected to the valve cavity 11.

[0047] Among them, see Figure 4 and Figure 5 As shown, a liquid inlet hole 16 and a pressure relief hole 17 are formed on the outer circumference of the first housing 1 . The liquid inlet hole 16 connects the valve cavity 11 with the first liquid inlet pipe 12 , and the pressure relief hole 17 connects the valve cavity 11 with the pressure relief pipe 13 .

[0048] The first liquid inlet pipe 12 is connected to the liquid inlet connecting pipe 6 so that the liquid in the liquid inlet connecting pipe 6 can flow into the valve cavity 11; the first liquid outlet pipe 14 is connected to the second shell 3 so that the liquid in the valve cavity 11 can flow into the second shell 3; the second liquid outlet pipe 15 is connected to the liquid outlet connecting pipe 8 so that the liquid in the valve cavity 11 can flow into the liquid outlet connecting pipe 8.

[0049] For the above valve core 2, if Figures 2 to 3 As shown, the valve core 2 is disc-shaped and is used to move along the axial direction of the first housing 1, and the central axis of the valve core 2 coincides with the central axis of the valve cavity 11. Figures 4 to 6 As shown, when the valve core 2 moves along the axial direction of the first housing 1, it can seal the first liquid outlet pipe 14 or the second liquid outlet pipe 15, thereby controlling the flow direction of the fluid and making the fluid flow to the second housing 3 or the liquid outlet pipe 8. Optionally, the valve core 2 at least partially includes an elastic material, for example, a sealing ring is provided or the whole is made of rubber material to enhance the sealing effect.

[0050] It can be understood that the present application realizes the control of the liquid flow direction by sealing the first liquid outlet pipe 14 or the second liquid outlet pipe 15, and the pressure relief component 5 is directly connected to the valve chamber 11. When the valve core 2 seals the first liquid outlet pipe 14 or the second liquid outlet pipe 15, the pressure relief component 5 is in a working state, so that one pressure relief component 5 can realize the pressure relief of two liquid passages, which can reduce the production cost.

[0051] For the second housing 3, Figures 1 to 3 As shown, the second housing 3 may be in the shape of a square tube, the inner cavity of which is cylindrical, and the central axis of the inner cavity of the second housing 3 coincides with the central axis of the valve cavity 11. The square tube-shaped second housing 3 is convenient for connection with the square flange of the first housing 1, for example, the flange of the first housing 1 is connected to the second housing 3 by screws.

[0052] like Figure 3 and Figure 5As shown, the second housing 3 is provided with a second liquid inlet pipe 31 and a through hole 32 at opposite ends along the axial direction, and a third liquid outlet pipe 33 is provided on one side of the second housing 3 along the diameter direction. The second liquid inlet pipe 31 and the third liquid outlet pipe 33 are both connected to the cavity in the second housing 3, and the second liquid inlet pipe 31 is connected to the first liquid outlet pipe 14, so that the liquid in the valve cavity 11 can flow from the second liquid inlet pipe 31 into the second housing 3, and then flow out from the third liquid outlet pipe 33, and the third liquid outlet pipe 33 is used to connect the pipeline. The through hole 32 is used for the drive component 4 to extend into the second housing 3 and the valve cavity 11, so as to be transmission-connected with the valve core 2.

[0053] In particular, if Figure 5 As shown, the end of the second liquid inlet pipe 31 is sleeve-connected with the end of the first liquid outlet pipe 14, and the end of the second liquid inlet pipe 31 is located inside the end of the first liquid outlet pipe 14. Then the driving assembly 4 can drive the valve core 2 to abut against the end surface of the second liquid inlet pipe 31 to seal the first liquid outlet pipe 14, so that the liquid flows out from the second liquid outlet pipe 15 along the flow direction L2. In the above manner, the first housing 1 does not need to be provided with a sealing structure corresponding to the valve core 2, which is conducive to simplifying the structure of the liquid valve device 100; and because the valve core 2 is against the end surface of the second liquid inlet pipe 31, when the liquid valve device 100 is disassembled and assembled, the valve core 2 can be disassembled and assembled together with the driving assembly 4, making the disassembly and assembly steps simpler and faster, which is conducive to improving the efficiency of assembly and maintenance.

[0054] For the above-mentioned drive component 4, as Figure 3 and Figure 5 As shown, the drive assembly 4 is arranged on the side of the second housing 3 facing away from the first housing 1, and the drive assembly 4 is sealed and connected to the through hole 32 to seal the through hole 32. The drive assembly 4 is provided with a square flange connected to the square tube-shaped second housing 3, for example, the flange of the drive assembly 4 is connected to the second housing 3 by screws.

[0055] The driving component 4 may be an electromagnetic driver, such as Figure 5 As shown, the drive assembly 4 includes a third housing 41, an electromagnet 42 and a drive shaft 43. The third housing 41 is sealed and connected with the through hole 32. The cavity in the third housing 41 is connected with the cavity in the second housing 3. The central axis of the cavity in the third housing 41 coincides with the central axis of the cavity in the second housing 3. The electromagnet 42 is arranged in the third housing 41, and the drive shaft 43 is arranged in the cavity of the third housing 41. The drive shaft 43 extends into the through hole 32 and passes through the second housing 3 to be transmission-connected with the valve core 2. The drive shaft 43 is magnetic. By changing the polarity of the electromagnet 42, the drive shaft 43 can be driven to move along the central axis of the third housing 41 to drive the valve core 2 to seal the first liquid outlet pipe 14 or the second liquid outlet pipe 15. Optionally, the electromagnet 42 is an electromagnetic coil surrounding the cavity in the third housing 41.

[0056] In particular, if Figure 6 As shown, the first housing 1 is provided with an extension tube 18, which is arranged in the valve cavity 11, one end of the extension tube 18 is connected with the second liquid outlet pipe 15, and the other end of the extension tube 18 extends toward the first liquid outlet pipe 14. Then the valve core 2 can abut against the end surface of the extension tube 18 facing the first liquid outlet pipe 14 to seal the second liquid outlet pipe 15, so that the liquid flows out from the third liquid outlet pipe 33 along the flow direction L1. In the above manner, the reciprocating formation of the valve core 2 can be shortened, and the response speed of the valve core 2 sealing the first liquid outlet pipe 14 or the second liquid outlet pipe 15 can be improved; and the length of the drive shaft 43 can be shortened and the outer dimensions of the third housing 41 can be reduced, which is conducive to reducing the size of the drive assembly 4.

[0057] For the above-mentioned pressure relief component 5, if Figures 7 to 9 As shown, the pressure relief assembly 5 includes a sealing cylinder 51, a sealing column 52, a pressure member 53, a first elastic member 54, a pressure relief cover 55 and a second elastic member 56. The sealing cylinder 51 is arranged in the pressure relief pipe 13, the sealing cylinder 51 is connected with the pressure relief hole 17, and the sealing column 52 is movably arranged in the sealing cylinder 51; the pressure member 53 is detachably arranged in the sealing cylinder 51, and the first elastic member 54 is supported between the sealing column 52 and the pressure member 53 so that the sealing column 52 abuts against the first sealing surface 511 of the inner wall of the sealing cylinder 51; the pressure relief cover 55 is detachably covered at the end of the pressure relief pipe, and the second elastic member 56 is supported between the pressure member 53 and the pressure relief cover 55 so that the second sealing surface 512 of the sealing cylinder 51 abuts against the edge of the pressure relief hole 17. It can be understood that the sealing cylinder 51, the sealing column 52 and the first elastic member 54 are all arranged in the pressure relief pipe, and the second elastic member 56 is partially arranged in the pressure relief pipe.

[0058] Among them, Fig. 9 As shown, when the sealing column 52 is tightly pressed against the first sealing surface 511 in the sealing cylinder 51, the cavity in the sealing cylinder 51 can be sealed, thereby sealing the pressure relief hole 17; when the second sealing surface 512 is pressed against the edge of the pressure relief hole 17, the sealing cylinder 51 and the pressure relief hole 17 can be sealed and connected.

[0059] For the above-mentioned sealing cylinder 51, as Figures 7 to 9 As shown, the sealing cylinder 51 is cylindrical and includes a first section 513 and a second section 514. The inner diameter of the second section 514 is greater than the inner diameter of the first section 513, the central axis of the cavity in the first section 513 coincides with the central axis of the cavity in the second section 514, the first sealing surface 511 connects the inner wall of the first section 513 and the inner wall of the second section 514, and the second sealing surface 512 connects the outer peripheral surface of the first section 513 and the outer peripheral surface of the second section 514.

[0060] The first section 513 is inserted into the pressure relief hole 17, and the second sealing surface 512 is against the edge of the pressure relief hole 17, and the second sealing surface 512 is adapted to the edge of the pressure relief hole 17, so that the first section 513 is sealed and connected to the pressure relief hole 17. In the embodiment of the present application, the edge of the pressure relief hole 17 is annular, and the second sealing surface 512 is annular.

[0061] Furthermore, if Figure 8 As shown, one end of the first section 513 inserted into the pressure relief hole 17 is circumferentially configured to be toothed, so that liquid can flow into the cavity of the first section 513 from the gap between the extension tube 18 and the first section 513 .

[0062] For the above-mentioned sealing column 52, if Figures 7 to 9 As shown, the sealing column 52 is cylindrical, and the sealing column 52 is movably arranged in the second section 514. The sealing column 52 is used to move along the axial direction of the sealing cylinder 51, and the central axis of the sealing column 52 coincides with the central axis of the cavity in the sealing cylinder 51. The first sealing surface 511 is adapted to the end surface of the sealing column 52, so that when the sealing column 52 abuts against the first contact surface, the first section 513 can be isolated from the second section 514, that is, the cavity in the sealing cylinder 51 is sealed. In the embodiment of the present application, the first sealing surface 511 is bowl-shaped, and the first sealing surface 511 can also be annular, conical, etc. Optionally, the sealing column 52 at least partially includes an elastic material, for example, a sealing ring is provided or the whole is made of rubber material to enhance the sealing effect.

[0063] For the above-mentioned pressing member 53, Figures 7 to 9 As shown, the pressing member 53 can be detachably connected to the sealing tube 51 by a buckle, and when the pressing member 53 is installed on the sealing tube 51, a gap exists between the pressing member 53 and the sealing tube 51 so that the liquid in the sealing tube 51 can flow out of the sealing tube 51.

[0064] For the first elastic member 54, Figures 7 to 9 As shown, one end of the first elastic member 54 facing the first housing 1 is supported on the sealing column 52, and the other end of the first elastic member 54 is supported on the pressing member 53. It can be understood that the first elastic member 54 applies an elastic force toward the first sealing surface 511 to the sealing column 52. When the thrust of the liquid in the first section 513 on the sealing column 52 is less than or equal to the elastic force, the first elastic member 54 drives the sealing column 52 to abut against the first sealing surface 511 and isolates the first section 513 from the second section 514; when the thrust of the liquid in the first section 513 on the sealing column 52 is greater than the elastic force, the liquid in the first section 513 pushes the sealing column 52 away, so that the sealing column 52 leaves the first sealing surface 511, and the first section 513 is connected with the second section 514, so that the liquid in the valve cavity 11 flows out through the sealing cylinder 51, and the hydraulic pressure in the valve cavity 11 is reduced. Optionally, the first elastic member 54 is a straight spring.

[0065] When the liquid in the first section 513 just pushes the sealing column 52, the hydraulic pressure in the valve chamber 11 is the preset hydraulic pressure, so that the pressure relief assembly 5 is used to connect the valve chamber 11 with the outside when the hydraulic pressure in the valve chamber 11 is greater than the preset hydraulic pressure to reduce the hydraulic pressure in the valve chamber 11.

[0066] For the above-mentioned pressure relief cover 55, if Figures 7 to 9 As shown, the pressure relief cover 55 and the first housing 1 are arranged to form a pressure relief chamber 57; the pressure relief cover 55 is provided with a pressure relief pipe 551, and the pressure relief pipe 551 is connected to the pressure relief chamber 57. The liquid flowing out of the sealing cylinder 51 can enter the pressure relief chamber 57 and flow out from the pressure relief pipe 551, that is, the liquid in the pressure relief chamber 57 is led out. Optionally, the pressure relief cover 55 and the pressure relief pipe 13 are detachably connected by a buckle, which is conducive to the rapid disassembly and maintenance of the pressure relief cover 55.

[0067] For the second elastic member 56, Figures 7 to 9 As shown, one end of the second elastic member 56 facing the first housing 1 is supported on the pressing member 53, and the other end of the second elastic member 56 is supported on the pressure relief cover 55, so as to drive the second sealing surface 512 to abut against the edge of the pressure relief hole 17 and connect the sealing cylinder 51 with the pressure relief hole 17. The second elastic member 56 makes the second sealing surface 512 tightly abut against the edge of the pressure relief hole 17, so that a good sealing effect is achieved between the sealing cylinder 51 and the first housing 1. Optionally, the second elastic member 56 is a straight spring.

[0068] It can be understood that the elastic force of the second elastic member 56 on the pressure member 53 is slightly greater than the elastic force of the first elastic member 54 on the sealing column 52. For example, the elastic force of the second elastic member 56 on the pressure member 53 is 105%, 110%, 120%, etc. of the elastic force of the first elastic member 54 on the sealing column 52. When the hydraulic pressure in the valve chamber 11 reaches the preset hydraulic pressure, the sealing column 52 will be pushed open preferentially.

[0069] It is worth noting that when the first elastic member 54 or the sealing column 52 is abnormal and the sealing column 52 cannot leave the first sealing surface 511, the hydraulic pressure in the valve cavity 11 will exceed the preset pressure. As the hydraulic pressure in the valve cavity 11 gradually increases, the liquid in the valve cavity 11 will push open the sealing cylinder 51, so that the second sealing surface 512 leaves the edge of the pressure relief hole 17, and the liquid in the valve cavity 11 can flow out from the gap between the pressure relief hole 17 and the sealing cylinder 51 to reduce the hydraulic pressure in the valve cavity 11. That is, through the design of the second elastic member 56 and the sealing cylinder 51, when the pressure relief between the sealing column 52 and the sealing cylinder 51 fails, a second pressure relief method can be formed to enhance the pressure relief effect.

[0070] For the above-mentioned liquid inlet pipe 6, if Figures 1 to 3As shown, one end of the liquid inlet pipe 6 is sleeve-connected with the first liquid inlet pipe 12, and the other end of the liquid inlet pipe 6 is used to connect the pipeline. When the liquid inlet pipe 6 is sleeve-connected with the first liquid inlet pipe 12, one end of the liquid inlet pipe 6 is inserted into the first liquid inlet pipe 12.

[0071] The liquid inlet pipe 6 is detachably connected to the first liquid inlet pipe 12. Figure 1 Zhihe Figure 3 As shown, the first liquid inlet pipe 12 is provided with a first clamping port 121, and the outer peripheral surface of the liquid inlet pipe 6 is provided with a first clamping groove 61, and the position of the first clamping groove 61 corresponds to the position of the first clamping port 121; the first clamping member 7 is provided on the first liquid inlet pipe 12, and is clamped with the first clamping groove 61 through the first clamping port 121. When the first clamping member 7 is clamped with the first clamping groove 61 through the first clamping port 121, the liquid inlet pipe 6 can be prevented from being pulled out of the first liquid inlet pipe 12; when the first clamping member 7 is pulled out of the first clamping port 121, the liquid inlet pipe 6 can be pulled out of the first liquid inlet pipe 12, thereby realizing the detachable connection between the liquid inlet pipe 6 and the first liquid inlet pipe 12.

[0072] Alternatively, if Figures 1 to 3 As shown, the liquid inlet pipe 6 is provided with a solenoid valve 62, through which the liquid can be turned on and off, that is, the liquid in the liquid inlet pipe 6 is allowed or prevented from flowing into the valve chamber 11. Optionally, as Figure 2 and Figure 5 As shown, the liquid inlet pipe 6 is also provided with a filter 63 for filtering the liquid flowing into the valve chamber 11 .

[0073] For the first card 7, Figures 1 to 3 As shown, the first clamping member 7 may be in a "U" shape. Figures 1 to 3 As shown, the number of the first clamping openings 121 and the first clamping slots 61 are both two, the two first clamping openings 121 are respectively located at the opposite sides of the first liquid inlet pipe 12 along a diameter direction, and the two first clamping slots 61 are respectively located at the opposite sides of the liquid inlet pipe 6 along a diameter direction; the two ends of the first clamping member 7 are respectively clamped with the two first clamping slots 61 through the two first clamping openings 121. The ends of the two ends of the first clamping member 7 are bent in a direction close to each other, so that when the two ends of the first clamping member 7 are respectively clamped with the two first clamping slots 61 through the two first clamping openings 121, the bent parts of the ends of the two ends of the first clamping member 7 can abut against the outer peripheral surface of the liquid inlet pipe 6 or the outer peripheral surface of the first liquid inlet pipe 12 to prevent the first clamping member 7 from being separated from the first clamping slots 61.

[0074] For the above-mentioned liquid outlet pipe 8, if Figures 1 to 3 As shown, one end of the liquid outlet pipe 8 is sleeve-connected with the second liquid outlet pipe 15, and the other end of the liquid outlet pipe 8 is used to connect the pipeline. When the liquid outlet pipe 8 is sleeve-connected with the second liquid outlet pipe 15, one end of the liquid outlet pipe 8 is inserted into the second liquid outlet pipe 15.

[0075] The liquid outlet pipe 8 is detachably connected to the second liquid outlet pipe 15. Figures 1 to 3 As shown, the second liquid outlet pipe 15 is provided with a second clamping port 151, and the outer peripheral surface of the liquid outlet pipe 8 is provided with a second clamping groove 81, and the position of the second clamping groove 81 corresponds to the position of the second clamping port 151; the second clamping member 9 is provided on the second liquid outlet pipe 15, and is clamped with the second clamping groove 81 through the second clamping port 151. When the second clamping member 9 is clamped with the second clamping groove 81 through the second clamping port 151, the liquid outlet pipe 8 can be prevented from being pulled out of the second liquid outlet pipe 15; when the second clamping member 9 is pulled out of the second clamping port 151, the liquid outlet pipe 8 can be pulled out of the second liquid outlet pipe 15, thereby realizing the detachable connection between the liquid outlet pipe 8 and the second liquid outlet pipe 15.

[0076] For the second card 9, Figure 2 and Figure 3 As shown, the second clamping member 9 can be a portion of a circular ring, such as a 3 / 4 ring. Figures 1 to 3 As shown, the second clamping groove 81 can be annular, and the second clamping member 9 penetrates the second liquid outlet pipe 15 through the second clamping port 151 and is clamped with the second clamping groove 81. The second clamping member 9 partially surrounds the liquid outlet pipe 8 to prevent the second clamping member 9 from escaping from the second clamping groove 81.

[0077] In some other embodiments, the second clamping member 9 may have the same shape as the first clamping member 7, for example, also in a "U" shape. Correspondingly, the number of the second clamping openings 151 and the number of the second clamping slots 81 are both two, the two second clamping openings 151 are respectively located on the opposite sides of the second liquid outlet pipe 15 along a diameter direction, and the two second clamping slots 81 are respectively located on the opposite sides of the liquid outlet pipe 8 along a diameter direction; the two ends of the second clamping member 9 are respectively clamped with the two second clamping slots 81 through the two second clamping openings 151.

[0078] The embodiment of the present application further provides a smart toilet (not shown), which includes a liquid valve device 100. The smart toilet has the structural features and beneficial effects of the liquid valve device 100, which will not be described in detail here.

[0079] The liquid valve device 100 and the smart toilet of the embodiment of the present application are provided with a pressure relief component 5 connected to the valve cavity 11. When the hydraulic pressure in the valve cavity 11 is greater than the preset hydraulic pressure, the pressure relief component 5 connects the valve cavity 11 with the outside, thereby reducing the hydraulic pressure in the valve cavity 11 to improve the problem of damage to the liquid valve device 100 due to excessive internal hydraulic pressure; and there are two pressure relief methods. When the first pressure relief method fails, the pressure can be relieved by the second pressure relief method to enhance the pressure relief effect. The pressure relief component 5 is directly connected to the valve cavity 11. When the valve core 2 seals the first liquid outlet pipe 14 or the second liquid outlet pipe 15, the pressure relief component 5 is in working state, so that one pressure relief component 5 can achieve pressure relief of two liquid passages, reducing production costs.
