[0031] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the exemplary embodiments is not meant to represent all embodiments in accordance with the present application. Rather, they are merely examples in accordance with some aspects of the present application as detailed in the appended claims.

[0032] In the prior art, the water inlet end of the instant water heater is provided with a flow adjusting structure and a switch structure. The flow adjusting structure is used to adjust the flow of the water inlet end, and thus the water outlet temperature of the instant water heater. The switch structure is used to open or close the water flow of the water inlet end. However, the flow adjusting structure and the switch structure are separately arranged at the water inlet end of the instant water heater, which results in a relatively complex structure of the water inlet end of the instant water heater, and a relatively high cost of arranging the flow adjusting structure and the switch structure. In addition, the switch structure usually includes a knob, which is rotated to the on or off position to open or close the water. However, it is inconvenient to rotate the knob.

[0033] To solve the above problems, the present application provides a flow adjusting valve structure, which includes a valve shell, a valve core, a conversion piece and a flow adjusting assembly. The valve shell has a flow passage therein, and the valve core is arranged in the valve shell. The conversion piece is arranged on the valve shell, and the valve core is switched between a first position and a second position by the conversion piece. In the first position, the flow of the liquid in the flow passage is blocked by the valve core to interrupt the flow passage. In the second position, the flow passage is in a communication state, and the liquid can flow in the flow passage. Thus, the flow passage can be interrupted or communicated by the conversion piece, so as to control the opening or closing of the flow adjusting valve structure. The flow adjusting assembly is arranged on the valve shell, and in the second position, the position of the valve core is adjusted by the flow adjusting assembly to adjust the volume of the valve core in the flow passage, and thus the flow area of the flow passage at the valve core for the liquid flow, so as to adjust the flow of the liquid out of the flow passage. The flow adjusting valve structure provided by the present application can realize the switch operation and the liquid flow adjusting operation at the same time, and the conversion piece and the flow adjusting assembly are both arranged on the valve shell, which is convenient to operate.

[0034] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can exist independently or in combination. Some concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0035] Reference Figures 1 to 5This application provides a flow control valve structure, including: a valve housing 100, a valve core 200, a switching element 300, and a flow control assembly 400. The valve housing 100 has a flow passage 110, and at least a portion of the valve core 200 is located within the valve housing 100.

[0036] The switching element 300 is installed on the valve housing 100. The switching element 300 switches the valve core 200 between a first position and a second position. In the first position, the valve core 200 interrupts the flow passage 110. In the second position, the flow passage 110 is connected.

[0037] The flow regulating component 400 is disposed on the valve housing 100. In the second position, the position of the valve core 200 is adjusted by the flow regulating component 400 to regulate the flow rate in the flow passage 110.

[0038] For example, one end of the flow channel 110 has an inlet 111 and the other end has an outlet 112. When the flow channel 110 is connected, liquid can enter the flow channel 110 through the inlet 111 and flow out through the outlet 112. The flow regulating valve structure can be a faucet, and the liquid flowing through the flow channel 110 can be water.

[0039] Specifically, refer to Figure 2 In the first position, the flow control valve structure is in the closed state. At least a portion of the valve core 200 is located within the flow passage 110, and the liquid within the flow passage 110 flows along... Figure 2 The liquid flows from the inlet 111 to the valve core 200 in the direction indicated by the middle arrow, and is blocked by the valve core 200, so that the liquid in the flow channel 110 cannot continue to flow to the outlet 112.

[0040] Reference Figure 3 In the second position, the flow control valve is in the open state. The valve core 200 can be located outside the flow passage 110; the valve core 200 will not affect the flow of liquid within the flow passage 110, and the liquid within the flow passage 110 can flow freely. Figure 3 The liquid flows from the inlet 111 to the outlet 112 in the direction indicated by the middle arrow, and then flows out through the outlet 112. Alternatively, the valve core 200 is partially located within the flow passage 110, but the valve core 200 does not disconnect the flow passage 110. The liquid in the flow passage 110 can still flow between the valve core 200 and the flow passage 110 and continue to flow to the outlet 112.

[0041] It should be noted that the flow rate of the liquid in the embodiments of this application refers to the volume of liquid flowing through per unit time.

[0042] The flow regulating valve structure provided by the embodiments of the present application can switch the valve core 200 to the first position or the second position through the conversion member 300. When the valve core 200 is in the first position, the flow of the liquid in the overflow passage 110 is blocked by the valve core 200, so as to interrupt the overflow passage 110. When the valve core 200 is in the second position, the overflow passage 110 is in a communication state, and the liquid can flow in the overflow passage 110. Thus, the interruption or communication of the overflow passage 110 can be controlled through the conversion member 300, so as to control the opening or closing of the flow regulating valve structure. When the valve core 200 is in the second position, the position of the valve core 200 is adjusted through the flow regulating assembly 400, so as to adjust the volume of the valve core 200 in the overflow passage 110, and then adjust the flowable area of the overflow passage 110 at the valve core 200, so as to adjust the flow of the liquid in the overflow passage 110. The flow regulating valve structure provided by the present application can realize the switching operation and the flow regulating operation at the same time, and the conversion member 300 and the flow regulating assembly 400 are both arranged on the valve housing 100, so the operation is relatively convenient.

[0043] With reference to Figure 2 and Figure 3 In some embodiments, the conversion member 300 moves towards the valve core 200, so as to drive the valve core 200 to move relative to the valve housing 100, so that the valve core 200 is switched from the second position to the first position.

[0044] Specifically, when the valve core 200 is in the second position, if it is needed to close the flow regulating valve structure, the conversion member 300 needs to be pressed, so as to move the conversion member 300 towards the valve core 200, and push the valve core 200 to move into the overflow passage 110, that is, the valve core 200 is moved to the first position, so as to close the flow regulating valve structure.

[0045] Thus, the flow regulating valve structure can be closed by moving the conversion member 300 towards the valve core 200, and the operation is relatively simple and convenient. Meanwhile, the structure of the flow regulating valve structure provided by the embodiments of the present application is relatively simple.

[0046] With reference to Figure 2 and Figure 3 The flow regulating valve structure provided by the embodiments of the present application further comprises an elastic member 500 arranged in the valve housing 100. When the valve core 200 is in the first position, the conversion member 300 moves towards the elastic member 500, so as to compress the elastic member 500. The elastic member 500 drives the conversion member 300 to reset, and the valve core 200 moves to the second position under the pressure of the liquid in the overflow passage 110.

[0047] For example, the elastic member 500 can be a spring.

[0048] In some embodiments, the conversion piece 300 comprises a pressing portion 310 and a limiting portion 320 connected with the pressing portion 310, and the limiting portion 320 is located between the pressing portion 310 and the valve core 200. The limiting portion 320 is provided with a limiting groove, and in the first position, the valve core 200 is inserted into the limiting groove from the end away from the overflow passage 110. Specifically, the part of the connecting rod 210 away from the overflow passage 110 is inserted into the limiting groove.

[0049] Specifically, in the first position, the conversion piece 300 abuts against one end of the valve core 200 to limit the valve core 200, and the conversion piece 300 abuts against the elastic piece 500. By pressing the conversion piece 300 towards the valve core 200, the conversion piece 300 moves towards the elastic piece 500 to compress the elastic piece 500, and the elastic force of the elastic piece 500 can drive the conversion piece 300 to move towards the side away from the valve core 200, and the conversion piece 300 releases the limitation on the valve core 200. At this time, the valve core 200 can move towards the conversion piece 300 under the pressure of the liquid in the overflow passage 110 to the second position.

[0050] Therefore, the flow regulating valve structure provided by the embodiments of the present application can realize one-key switching function, and the operation is relatively simple and convenient.

[0051] With reference to Figure 2 and Figure 3 In some embodiments, the flow regulating assembly 400 comprises a rotating piece 410, and the rotating piece 410 is rotationally arranged on the valve housing 100. In the second position, the rotating piece 410 rotates relative to the valve housing 100 to drive the valve core 200 to move relative to the valve housing 100 to adjust the position of the valve core 200.

[0052] Specifically, by rotating the rotating piece 410 relative to the valve housing 100 to drive the valve core 200 to move relative to the valve housing 100, the volume of the valve core 200 in the overflow passage 110 is adjusted, the flow-through area of the overflow passage 110 at the valve core 200 is adjusted, and thus the flow rate of the liquid flowing through the valve core 200 is adjusted, and the flow rate of the liquid flowing out of the liquid outlet 112 is adjusted.

[0053] Therefore, by rotating the rotating piece 410 relative to the valve housing 100, the flow rate of the liquid flowing out of the overflow passage can be adjusted, and the operation is relatively simple and convenient.

[0054] With reference to Figure 2 and Figure 3 In some embodiments, the flow regulating assembly 400 further comprises a moving piece 420, and the rotating piece 410 is in transmission connection with the moving piece 420. The rotating piece 410 rotates relative to the valve housing 100 to drive the moving piece 420 to move relative to the valve housing 100, and the moving piece 420 drives the valve core 200 to move relative to the valve housing 100.

[0055] The rotating member 410 is rotated relative to the valve housing 100 to control the distance that the moving member 420 moves relative to the valve housing 100, and thus the distance that the valve core 200 moves relative to the valve housing 100, the volume of the part of the valve core 200 extending into the flow passage 110, and the flow rate of the liquid flowing out of the outlet 112 of the flow passage 110.

[0056] For example, the rotating member 410 is threadedly connected to the moving member 420, and the rotating member 410 is rotated relative to the valve housing 100 to drive the moving member 420 to move relative to the valve housing 100.

[0057] Specifically, when in the second position, the rotating member 410 is rotated in a first direction to drive the moving member 420 to move the valve core 200 towards the flow passage 110, and the rotating member 410 is rotated in a second direction opposite to the first direction to drive the moving member 420 to move away from the flow passage 110, at this time, the valve core 200 is moved away from the flow passage 110 under the action of the pressure of the liquid in the flow passage 110, and thus the position of the valve core 200 can be adjusted. One of the first direction and the second direction is clockwise, and the other is counterclockwise.

[0058] Referring to Figure 2 , Figure 3 and Figure 4 , the valve core 200 has an abutting portion 240, and when in the second position, the moving member 420 abuts against the abutting portion 240.

[0059] The moving member 420 abuts against the abutting portion 240, so that when the moving member 420 moves towards the flow passage 110, the valve core 200 can be driven to move towards the flow passage 110. At the same time, when in the second position, the moving member 420 can limit the abutting portion 240, and thus the valve core 200 can be limited at the current position.

[0060] For example, the abutting portion 240 is arranged on the connecting rod 210, and the second blocking portion 230 is located between the abutting portion 240 and the first blocking portion 220. The moving member 420 is located above the abutting portion 240, and the moving member 420 is sleeved on the connecting rod 210.

[0061] Specifically, in the second position, by rotating the rotating member 410 relative to the valve housing 100 in the first direction, the moving member 420 is driven to move toward the flow channel 110. Simultaneously, the moving member 420 pushes the abutment portion 240 toward the flow channel 110, thus pushing the valve core 200 toward the flow channel 110. By rotating the rotating member 410 relative to the valve housing 100 in the second direction, the moving member 420 is driven to move toward the side opposite to the flow channel 110, causing the moving member 420 to disengage from the abutment portion 240. At this time, the valve core 200 can move toward the side opposite to the flow channel 110 under the action of the liquid pressure within the flow channel 110.

[0062] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments, the flow control assembly 400 further includes a handle 430, which is rotatably connected to the valve housing 100 and connected to the rotating member 410.

[0063] Specifically, by setting a handle 430, rotating the handle 430 relative to the valve housing 100 can drive the rotating component 410 to rotate relative to the valve housing 100. This facilitates the rotation of the rotating component 410 relative to the valve housing 100.

[0064] For example, the handle 430 is located on one side of the valve housing 100 and is rotatably connected to the valve housing 100, and a portion of the rotating part 410 is located inside the valve housing 100.

[0065] Furthermore, the handle 430 has a mounting groove, and the valve housing 100 has a protrusion. The protrusion is inserted into the mounting groove to make the connection between the handle 430 and the valve housing 100 more stable and reliable.

[0066] Reference Figure 2 , Figure 3 and Figure 5 In a specific implementation, the valve housing 100 has a mounting cavity 411, which is connected to the flow passage 110, and at least part of the valve core 200 is located in the mounting cavity 411.

[0067] The valve core 200 can be partially inserted into the flow channel 110 through the mounting cavity 411.

[0068] For example, the flow channel 110 includes an inlet section 113, an outlet section 114, and a connecting section 115. The connecting section 115 connects the inlet section 113 and the outlet section 114. The inlet port 111 is located at the end of the inlet section 113 away from the connecting section 115, and the outlet port 112 is located at the end of the outlet section 114 away from the connecting section 115. Liquid enters the flow channel 110 through the inlet port 111 and flows sequentially through the inlet section 113, the connecting section 115, and the outlet section 114 to the outlet port 112.

[0069] In some examples, at least part of the rotating member 410 is located within the valve housing 100, and a mounting cavity 411 is formed within the rotating member 410.

[0070] The valve housing 100 includes a first section 120 and a second section 130, with the second section 130 disposed on the first section 120 and the first and second sections 120 inclined towards each other. An inlet section 113 and an outlet section 114 are both located within the first section 120, a mounting cavity 411 is located within the second section 130, and a connecting section 115 is located between the first and second sections 120 and communicates with the mounting cavity 411. For example, the second section 130 is perpendicular to the first section 120.

[0071] Specifically, the valve core 200 moves along the mounting cavity 411 toward the connecting section 115 until it is inserted into the connecting section 115, thereby blocking the connection between the inlet section 113 and the connecting section 115, or blocking the connection between the connecting section 115 and the outlet section 114, thus preventing liquid from flowing into the outlet section 114. When part of the valve core 200 is inserted into the connecting section 115, it blocks part of the connection between the inlet section 113 and the connecting section 115, or blocks part of the connection between the connecting section 115 and the outlet section 114, thereby regulating the flow rate of liquid into the outlet section 114.

[0072] In some embodiments, the valve housing 100 has a filter section 140 disposed between the connecting section 115 and the inlet section 113, and / or the filter section 140 is disposed within the inlet section 113 to filter impurities in the liquid flowing from the inlet section 113 to the connecting section 115, thereby ensuring that there are fewer impurities in the liquid flowing from the connecting section 115 to the outlet section 114.

[0073] Furthermore, the filter section 140 may be a filter screen. In some examples, the rotating member 410 has a partition 412 that divides the mounting cavity 411 into a first cavity 413 and a second cavity 414, with the second cavity 414 connecting the first cavity 413 and the connecting section 115. The moving member 420 and the abutment portion 240 are located within the second cavity 414, and the moving member 420 is located between the abutment portion 240 and the partition 412, which limits the movement of the moving member 420.

[0074] For example, the inner wall of the second cavity 414 has an internal thread, and the moving part 420 has an external thread, with the internal thread and the external thread connected.

[0075] In some embodiments, the flow control assembly 400 further includes a connector 440 located within the rotating member 410, the connector 440 connecting the rotating member 410 to the rotating member 410. For example, the connector 440 is threadedly connected to the rotating member 410.

[0076] In some embodiments, the valve housing 100 further includes a retainer 150 disposed within the second segment 130, and a rotating member 410 inserted into the retainer 150 and rotatable relative to the retainer 150. Exemplarily, the retainer 150 is threadedly connected to the second segment 130.

[0077] In some examples, the elastic element 500 is located within the first cavity 413, and one end of the elastic element 500 abuts against the partition 412. In the first position, the conversion element 300 abuts against the other end of the elastic element 500, so that the conversion element 300 moves toward the elastic element 500, thereby compressing the elastic element 500.

[0078] Reference Figure 2 and Figure 3 In a specific implementation, the flow regulating valve structure provided in this application embodiment also includes a pressing member 600. The pressing member 600 is disposed on the handle 430 and is located on the side of the switching member 300 away from the valve core 200. The pressing member 600 drives the valve core 200 to switch between a first position and a second position through the switching member 300.

[0079] In the second position, the conversion member 300 abuts against the pressing member 600 to limit the conversion member 300 by the pressing member 600.

[0080] For example, the pressing element 600 may be deformable. For instance, the pressing element 600 may be a silicone part.

[0081] Specifically, the handle 430 has a clearance groove 431, the bottom of which communicates with the first cavity 413. At least a portion of the conversion member 300 is located within the clearance groove 431, and the pressing member 600 covers the opening of the clearance groove 431 and is connected to the handle 430. The clearance groove 431 is used to avoid the pressing member 600.

[0082] By pressing the pressing member 600 towards the bottom of the clearance groove 431, the pressing member 600 is deformed and abuts against the end face of the conversion member 300 away from the valve core 200, thereby pushing the conversion member 300 towards the valve core 200.

[0083] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the valve core 200 has a first blocking part 220 and a second blocking part 230. In the first position, the first blocking part 220 is located in the flow passage 110 to interrupt the flow passage 110, and the second blocking part 230 blocks the connection between the flow passage 110 and the mounting cavity 411.

[0084] Specifically, by sealing the connection between the connecting section 115 and the mounting cavity 411 by the valve core 200, the liquid in the connecting section 115 cannot flow into the mounting cavity 411, thus preventing the liquid from contacting the structure inside the mounting cavity 411 and affecting the structure inside the mounting cavity 411.

[0085] For example, the connecting rod 210, the first sealing part 220, and the second sealing part 230 are coaxially connected. The connecting section 115 is located between the mounting cavity 411 and the liquid outlet section 114, and the mounting cavity 411 is located above the connecting section 115, while the liquid inlet section 113 is located on one side of the connecting section 115.

[0086] In some examples, the elastic element 500 is fitted onto the connecting rod 210 of the valve core 200.

[0087] Specifically, in the first position, the first sealing part 220 is located within the connection between the connecting section 115 and the outlet section 114, blocking the connection between the connecting section 115 and the outlet section 114, preventing liquid from flowing into the outlet section 114. The second sealing part 230 is located within the connection between the connecting section 115 and the mounting cavity 411, blocking the connection between the connecting section 115 and the mounting cavity 411. In the second position, when the valve core 200 is outside the flow channel 110, the first sealing part 220 is located within the connection between the connecting section 115 and the mounting cavity 411. In the second position, when the valve core 200 is partially located within the flow channel 110, the second sealing part 230 is located within the connection between the connecting section 115 and the mounting cavity 411. By adjusting the volume of the first sealing part 220 extending into the connecting section 115, the flow rate of liquid flowing into the connecting section 115 via the inlet section 113 is adjusted.

[0088] Reference Figure 2 , Figure 3 and Figure 4 The flow regulating valve structure provided in this application embodiment also includes at least two seals 700. In the first position, the seals 700 are connected between the first sealing part 220 and the inner wall of the valve housing 100, and / or, the seals 700 are connected between the second sealing part 230 and the inner wall of the valve housing 100.

[0089] The sealing element 700 is provided to prevent liquid from flowing out between the first sealing part 220 and the inner wall of the valve housing 100, or to prevent liquid from flowing out between the second sealing part 230 and the inner wall of the valve housing 100.

[0090] For example, seal 700 is a sealing ring.

[0091] In some examples, the first sealing portion 220 includes a coaxially connected cylindrical section 221 and a tapered section 222, with the tapered section 222 located below the cylindrical section 221. The cylindrical section 221 has an annular groove, within which the seal 700 is located. The structure of the second sealing portion 230 may be the same as that of the first sealing portion 220.

[0092] In some embodiments, the valve housing 100 has a first abutting section and a second abutting section, which are located on the lower and upper sides of the connecting section 115, respectively. In the first position, the seal 700 seals the first blocking part 220 with the first abutting section, and at the same time, the seal 700 seals the second blocking part 230 with the second abutting section.

[0093] For example, the valve housing 100 also includes a connecting member disposed between the first segment 120 and the second segment 130, with the connecting segment 115, the first abutting segment, and the second abutting segment all located on the connecting member. Furthermore, the filter section 140 is located on the connecting member.

[0094] Based on the above embodiments, this application provides a water heater, including a water heater body and any of the flow regulating valve structures in the above embodiments disposed on the water heater body.

[0095] The specific structure of the flow regulating valve has been described in detail in the above embodiments, and will not be repeated here.

[0096] For example, the water heater can be an instant water heater.

[0097] Specifically, the water heater includes an inlet pipe, and a flow control valve structure can be installed on the inlet pipe. The flow passage 110 of the flow control valve structure is connected to the inlet pipe. The inlet pipe is opened or closed by pressing the switching element 300 of the flow control valve structure. The flow rate of the inlet pipe is adjusted by rotating the rotating element 410 of the flow control valve structure relative to the valve body 100 of the flow control valve structure.

[0098] The water heater provided in this application embodiment has a flow regulating valve structure that allows the valve core 200 to be moved to a first position or a second position via a switching component 300. In the first position, the valve core 200 blocks the flow of water within the flow channel 110, thus interrupting the flow channel 110. In the second position, the flow channel 110 is open, allowing water to flow within it. Therefore, the switching component 300 can control the interruption or opening of the flow channel 110, thereby controlling the opening or closing of the flow regulating valve structure. The position of the valve core 200 is adjusted by the flow regulating component 400 to adjust its volume within the flow channel 110, thereby adjusting the flowable area of ​​the flow channel 110 at the valve core 200, and thus regulating the flow rate of water flowing out of the flow channel 110. The flow regulating valve structure provided in this application can simultaneously achieve on / off operation and flow rate adjustment operation.
