Description

Technical Field

[0001] The present application relates to the technical field of the water circuit system of a wall-mounted boiler, and in particular to a servo mixing valve and an integrated water circuit system with a servo mixing valve. Background Art

[0002] A wall-mounted boiler is a heating device installed on a wall, and is mainly used for supplying hot water for floor heating and bathroom use. A water circuit system is arranged inside the wall-mounted boiler, and the water circuit system is mainly used to control the flow direction of the water circuit, so that the wall-mounted boiler can switch between the floor heating state and the bathroom state as required.

[0003] In the existing water circuit system of a wall-mounted boiler, such as a low-position side-insert integrated water circuit disclosed in the authorized publication number CN215809268U, it includes a plate heat exchanger, a water inlet module and a water outlet module. A first exchange pipe and a second exchange pipe are arranged inside the plate heat exchanger. The water inlet module and the water outlet module are connected through the plate heat exchanger. The water inlet module includes a water pump and an integrated interface component. The water outlet module includes a multi-channel switching integrated block, a one-way return component and a channel switching component; the flow direction of the water circuit is controlled by the cooperation of the water inlet module and the water outlet module, so that the wall-mounted boiler switches to the floor heating state or the bathroom state.

[0004] When the wall-mounted boiler switches to the bathroom state, the water inlet module and the water outlet module cooperate to control the water circuit to form a circulating water flow and a bathroom water flow. The circulating water flow and the bathroom water flow respectively flow through the first exchange pipe and the second exchange pipe and generate heat exchange, so that the bathroom water flow is heated and flows out for use.

[0005] However, when the water pressure and flow rate of the bathroom water flow are low and the water temperature of the circulating water flow is high, excessive heat exchange occurs between the circulating water flow and the bathroom water flow, which will cause the temperature of the bathroom water flow to be too high when heated, thus causing discomfort to the user; therefore, further improvement can be made. Summary of the Invention

[0006] In order to reduce the temperature of the bathroom hot water when the water pressure and flow rate of the bathroom water flow are low and the water temperature of the circulating water flow is high, and to avoid the hot water temperature output from the mixed water outlet channel being too high or too low and causing discomfort to the user, the present application provides a servo mixing valve and an integrated water circuit system with a servo mixing valve.

[0007] In a first aspect, the present application provides a servo mixing valve, which includes a valve body module provided with a first water inlet channel, a second water inlet channel, and a mixed water outlet channel that are interconnected; a valve core module, which includes an adjustment mechanism and a transmission mechanism. The transmission mechanism is arranged in the valve body module, the adjustment mechanism is arranged at the output end of the transmission mechanism, and the adjustment mechanism is located at the corresponding position inside the first water inlet channel; a servo module is arranged in the valve body module, the input end of the transmission mechanism is arranged at the output end of the servo module, and the servo module drives the adjustment mechanism to move to block or disengage from the first water inlet channel through the transmission mechanism; a sensing module is arranged in the valve body module, and the sensing end of the sensing module is located at the corresponding position inside the mixed water outlet channel. A control module is connected between the sensing module and the servo module.

[0008] Through the above technical solution, under normal conditions, hot water flows through the second water inlet channel and the mixed water outlet channel in sequence for output; when the sensing module detects that the hot water temperature output from the mixed water outlet channel is higher than the preset temperature value, it feeds back the situation to the control module. The control module controls the servo module to drive the output end of the transmission mechanism to move upward. The output end of the transmission mechanism drives the adjustment mechanism to move upward to disengage from the first water inlet channel, so that cold water enters the second water inlet channel and is mixed with the hot water and then output from the mixed water outlet channel. At this time, the control module controls the operation of the servo module according to the real-time monitoring of the sensing module, so that the gap between the adjustment mechanism and the first water inlet channel and the corresponding cold water flow rate are kept within a reasonable range, realizing to avoid the hot water temperature output from the mixed water outlet channel being too high and causing discomfort to the user.

[0009] Optionally, the transmission mechanism includes a fixed component, a movable component, a transmission component, a first sealing component, and a second sealing component. The fixed component is fixedly arranged in the valve body module, the first sealing component is connected between the fixed component and the valve body module, the movable component is threadedly connected to the fixed component, the movable component is slidably clamped to the output end of the servo module, so that the servo module is used to drive the movable component to rotate, and the movable component moves linearly relative to the fixed component and the servo module during rotation. One end of the transmission component is connected to the movable component, the end of the transmission component away from the movable component penetrates through the fixed component, and the end of the transmission component away from the movable component is connected with the adjustment mechanism. The second sealing component is connected between the transmission component and the fixed component.

[0010] Optionally, the valve body module is provided with a stepped groove, the fixed component is embedded in the stepped groove, the first sealing component includes multiple groups of first sealing rings, the fixed component is provided with multiple groups of first sealing grooves, the multiple groups of first sealing rings are respectively embedded in the multiple groups of first sealing grooves, and the multiple groups of first sealing rings are all in contact with the stepped grooves; the fixed component is provided with an internal thread, and one end of the movable component is provided with an external thread connected and adapted to the internal thread, so that the movable component can move linearly relative to the fixed component during rotation; the movable component is provided with a clamping column at one end away from the external thread, and the servo module A snap-in groove is provided at the output end of the block, and a sliding snap-in arrangement is provided between the snap-in column and the snap-in groove so that the movable component can move linearly relative to the servo module during rotation; the second sealing component includes multiple groups of second sealing rings and limiting members, the fixed component is provided with a second sealing groove, multiple groups of second sealing rings are all embedded in the second sealing groove, multiple groups of second sealing rings are all abutted against the transmission component, and a pressure equalizing member is provided between two adjacent groups of second sealing rings, the fixed component is provided with a limiting groove, the limiting member is embedded in the limiting groove and is used to limit the second sealing ring from leaving the second sealing groove.

[0011] Through the above technical solution, when the servo module is driven by external power, the output end of the servo module drives the movable component to rotate through the clamping column and the clamping groove, and the movable component realizes linear up and down movement relative to the fixed component through threaded cooperation. At the same time, the movable component moves linearly up and down relative to the output end of the servo module. In the process of linear up and down movement of the movable component, the clamping limit of the first limit mechanism and the second limit mechanism is used to drive the transmission component and the plug mechanism to move linearly up and down synchronously, that is, the output end of the transmission mechanism has the function of moving up and down when driven by external power.

[0012] Optionally, the adjusting mechanism includes a piston assembly and a third sealing ring, the piston assembly is provided with a third sealing groove, the third sealing ring is embedded in the third sealing groove, and the third sealing ring and the first water inlet channel are both provided with matching abutment slopes; the movable assembly and the piston assembly are both provided with connecting holes, the two ends of the transmission assembly are respectively penetrated through two groups of connecting holes, and the transmission assembly is provided with a first limiting mechanism at corresponding positions on both sides of the movable assembly, and the transmission assembly is provided with a second limiting mechanism at corresponding positions on both sides of the piston assembly; the valve body module is provided with a guide assembly at a corresponding position below the piston assembly, and the transmission assembly is penetrated through the guide assembly.

[0013] Through the above technical solution, when the output end of the transmission mechanism drives the adjusting mechanism to move downward, the abutting inclined surface of the third sealing ring is pressed against the abutting inclined surface of the first water inlet channel, so that the adjusting mechanism seals the first water inlet channel, preventing cold water from being injected into the first water inlet channel; when the output end of the transmission mechanism drives the adjusting mechanism to move upward, the abutting inclined surface of the third sealing ring is separated from the abutting inclined surface of the first water inlet channel, so that the adjusting mechanism disengages from the first water inlet channel, enabling cold water to be injected into the first water inlet channel.

[0014] Optionally, both the first limiting mechanism and the second limiting mechanism include two sets of elastic snap rings. The four sets of elastic snap rings are all snap-connected to the transmission component. The two elastic snap rings of the first limiting mechanism are respectively located on the upper and lower sides of the movable component, and the two elastic snap rings of the second limiting mechanism are respectively located on the upper and lower sides of the piston component.

[0015] Through the above technical solution, through the snap connection and limitation of the first limiting mechanism and the second limiting mechanism, when the movable component moves linearly up and down, the plugging mechanism is driven to move linearly up and down synchronously through the transmission component.

[0016] Optionally, the first limiting mechanism includes two sets of elastic snap rings. The two sets of elastic snap rings are all snap-connected to the transmission component, and the two sets of elastic snap rings are respectively located on the upper and lower sides of the movable component; the second limiting mechanism includes a mounting block, a fixed magnetic part, a follower magnetic part, and a buffer spring. The mounting block is fixedly arranged on the transmission component and is located above the piston component. The fixed magnetic part is fixedly arranged on the transmission component and is located below the piston component. The follower magnetic part is fixedly arranged on the piston component. The buffer spring is connected between the mounting block and the piston component, so that the piston component always has a tendency to move downward until the fixed magnetic part and the follower magnetic part are in contact.

[0017] Through the above technical solution, when the servo module drives the transmission component to move upward as an external power, the transmission component drives the adjustment mechanism to move upward through the second limiting mechanism until it disengages from the first water inlet passage. At this time, the buffer spring pushes the piston assembly to move downward until the fixed magnetic part and the follower magnetic part are in contact with each other to form a magnetic attraction effect. Under the dual action of the elastic force and the magnetic attraction force, the piston assembly can have good stability and is not prone to shaking up and down, so that the gap size between the adjustment mechanism and the first water inlet passage and the corresponding cold water flow rate have good stability; on the contrary, when the servo module drives the transmission component to move downward as an external power, the transmission component drives the adjustment mechanism to move downward through the second limiting mechanism until it blocks the first water inlet passage. At this time, if the servo module runs excessively and causes the transmission component to move downward excessively, the fixed magnetic part and the follower magnetic part are separated and the buffer spring is compressed, so that the transmission component can continue to move downward relative to the adjustment mechanism, minimizing the damage caused by excessive extrusion between the third sealing ring of the adjustment mechanism and the first water inlet passage and ensuring the stability of the structure.

[0018] Optionally, a stirring component is arranged at a corresponding position inside the first water inlet passage of the valve body module. The stirring component is slidably clamped to the transmission component. A rotating component is arranged at a corresponding position below the first water inlet passage of the valve body module. When the moving component drives the transmission component to move linearly to a predetermined position through the first limiting mechanism, the rotating component drives the stirring component to rotate through the transmission component.

[0019] Through the above technical solution,

[0020] Optionally, the stirring component includes a sliding ring and a stirring frame. The sliding ring is slidably sleeved on the transmission component. The sliding ring is fixedly provided with a transmission block. The transmission component is provided with a transmission groove that is slidably adapted to the transmission block. The stirring frame is fixedly provided on the sliding ring; the rotating component includes an installation chamber, a rotating part, a guiding cylinder, a thrust rod, and a thrust spring. The installation chamber is fixedly provided in the first water inlet passage. One end of the transmission component away from the moving component extends into the installation chamber. The rotating part is fixedly provided at one end of the transmission component away from the moving component. Four groups of wedge blocks are fixedly provided on the rotating part along its axis. The guiding cylinder is fixedly provided in the installation chamber. Eight groups of avoidance grooves are arranged along the axis of the guiding cylinder. The avoidance grooves are inserted and adapted to the wedge blocks. An inclined wedge surface is arranged between adjacent two groups of avoidance grooves. The thrust rod is slidably arranged in the guiding cylinder. Eight groups of guiding teeth are arranged along the axis of the thrust rod. The unfolded surface of the guiding teeth is an isosceles triangle structure, and the tip of the guiding teeth is aligned with the center of the avoidance groove; the thrust spring is connected between the installation chamber and the thrust rod to make the thrust rod always have a tendency to move upward until the guiding teeth exceed the inclined wedge surface.

[0021] Through the above technical solution, during the rotation of the transmission assembly, the stirring frame is driven to rotate through the cooperation of the transmission block and the transmission groove, so that the stirring frame cleans the inner wall of the first water inlet channel, and tries to avoid excessive attachment of impurities; due to the difference in the water flow velocity in each area of the gap between the adjusting mechanism and the first water inlet channel, the wear rate of each area of the third sealing ring by the impurities in the water flow is also different. In addition, during the rotation of the transmission assembly, the third sealing ring is driven to rotate through the second limiting mechanism, which can make each area of the third sealing ring rotate and switch continuously to cope with wear, thereby reducing the overall wear rate of the third sealing ring.

[0022] Optionally, the mixed water outlet channel includes a first mixing section, a second mixing section and a third mixing section connected in sequence. The first mixing section is connected to the valve body module. The sensing end of the sensing module is arranged in the third mixing section. The included angle between the first mixing section and the second mixing section is 90 degrees, and the second mixing section and the third mixing section are arranged in parallel.

[0023] Through the above technical solution, when the cold water injected into the first water inlet channel and the hot water injected into the second water inlet channel converge in the first mixing section, the cold water and the hot water flow through the second mixing section and the third mixing section in sequence and then are output. During the process of flowing from the first mixing section to the second mixing section and from the second mixing section to the third mixing section, the cold water and the hot water can be mixed more fully, thereby improving the uniformity of the hot water output from the mixed water outlet channel.

[0024] In a second aspect, the present application provides an integrated waterway system with a servo mixing valve, including a basic waterway structure and a servo mixing valve. The basic waterway structure is provided with a bathroom water inlet interface and a bathroom water outlet interface. The second water inlet channel of the servo mixing valve is connected to the bathroom water outlet interface, and the first water inlet channel of the servo mixing valve is connected to the bathroom water inlet interface.

[0025] Through the above technical solution, in the special state where the cold water pressure output by the faucet is relatively low, even if the power of the burner is reduced to the lowest value, since the cold water flow rate in the basic waterway structure is too slow and excessive heat exchange occurs with the hot water, the temperature of the bathroom hot water output is too high. At this time, when the sensing module detects that the hot water temperature output by the mixed water outlet channel is higher than the preset temperature value, it feeds back the situation to the control module. The control module controls the servo module to drive the output end of the transmission mechanism to move upward. The output end of the transmission mechanism drives the adjustment mechanism to move upward to disengage from the first water inlet channel, so that part of the cold water of the faucet sequentially passes through the connecting pipe and the first water inlet channel and flows to the second water inlet channel. After this part of the cold water is mixed with the hot water, it is output by the mixed water outlet channel, thus reducing the temperature of the bathroom hot water. At this time, the control module controls the operation of the servo module according to the real-time monitoring of the sensing module, so that the gap between the adjustment mechanism and the first water inlet channel and the corresponding cold water flow rate are kept within a reasonable range, avoiding discomfort to the user caused by the hot water temperature output by the mixed water outlet channel being too high or too low.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] In the application of the waterway system of the wall-mounted boiler, in the normal state, the hot water heated by the burner circulates in the basic waterway structure, and the cold water output by the faucet flows in the basic waterway structure and exchanges heat with the hot water, thereby realizing the output of bathroom hot water. In the special state where the cold water pressure output by the faucet is relatively low, even if the power of the burner is reduced to the lowest value, since the cold water flow rate in the basic waterway structure is too slow and excessive heat exchange occurs with the hot water, the temperature of the bathroom hot water output is too high. At this time, when the sensing module detects that the hot water temperature output by the mixed water outlet channel is higher than the preset temperature value, it feeds back the situation to the control module. The control module controls the servo module to drive the output end of the transmission mechanism to move upward. The output end of the transmission mechanism drives the adjustment mechanism to move upward to disengage from the first water inlet channel, so that part of the cold water of the faucet sequentially passes through the connecting pipe and the first water inlet channel and flows to the second water inlet channel. After this part of the cold water is mixed with the hot water, it is output by the mixed water outlet channel, thus reducing the temperature of the bathroom hot water. At this time, the control module controls the operation of the servo module according to the real-time monitoring of the sensing module, so that the gap between the adjustment mechanism and the first water inlet channel and the corresponding cold water flow rate are kept within a reasonable range, avoiding discomfort to the user caused by the hot water temperature output by the mixed water outlet channel being too high or too low.

Specifically, the cross-sections of the clamping column 228 and the clamping groove 229 are both set in a plum blossom shape / hexagonal shape and other structures, which can not only realize the clamping and driving of rotation, but also realize relative sliding, so as to realize the sliding clamping arrangement between the clamping column 228 and the clamping groove 229, so that the output end of the servo module 3 can drive the movable component 222 to rotate, and at the same time enable the movable component 222 to move linearly up and down relative to the fixed component 221 and the servo module 3 during rotation.The transmission component 223 is specifically a transmission round shaft structure. The top end of the transmission component 223 is connected to the movable component 222, and the bottom end of the transmission component 223 penetrates through the fixed component 221.

[0046] When the servo module 3 is used as an external power drive, the output end of the servo module 3 drives the movable component 222 to rotate through the cooperation of the clamping post 228 and the clamping groove 229. The movable component 222 realizes linear up and down movement relative to the fixed component 221 through screw cooperation. The movable component 222 also moves linearly up and down relative to the output end of the servo module 3. And during the process of the linear up and down movement of the movable component 222, the transmission component 223 and the plug mechanism are driven to move linearly up and down synchronously through the snap connection and limitation of the first limiting mechanism 5 and the second limiting mechanism 6, that is, the output end of the transmission mechanism 22 has the function of moving up and down when driven by an external power.

[0047] In the above, the adjusting mechanism 21 moves downward to block the first water inlet channel 11 or moves upward to disengage from the first water inlet channel 11, which is specifically shown in this embodiment as:

[0048] The adjusting mechanism 21 specifically includes a piston assembly 211 and a third sealing ring 212. Among them, the piston assembly 211 is located at the connection between the first water inlet channel 11 and the valve body module 1. A connection hole for the transmission assembly 223 to pass through is provided in the center of the piston assembly 211. And two sets of elastic retaining rings of the second limiting mechanism 6 are respectively located on the upper and lower sides of the piston assembly 211. A third sealing groove is provided on the outer periphery of the piston assembly 211. The third sealing ring 212 is embedded in the third sealing groove, and both the third sealing ring 212 and the first water inlet channel 11 are provided with mating abutting inclined surfaces.

[0049] When the output end of the transmission mechanism 22 drives the adjusting mechanism 21 to move downward, the abutting inclined surface of the third sealing ring 212 is pressed against the abutting inclined surface of the first water inlet channel 11, so as to realize that the adjusting mechanism 21 blocks the first water inlet channel 11 and makes the first water inlet channel 11 unable to inject cold water. When the output end of the transmission mechanism 22 drives the adjusting mechanism 21 to move upward, the abutting inclined surface of the third sealing ring 212 is separated from the abutting inclined surface of the first water inlet channel 11, so as to realize that the adjusting mechanism 21 disengages from the first water inlet channel 11 and makes the first water inlet channel 11 able to inject cold water.

[0050] In this embodiment, a guiding component 7 is provided at the corresponding position below the piston assembly 211 of the valve body module 1. The guiding component 7 is a guiding block, and the guiding block is fixedly arranged on the inner wall of the first water inlet channel 11. The guiding block is provided with a guiding hole adapted to the transmission assembly 223, and the transmission assembly 223 is arranged through the guiding component 7.

[0051] When the adjusting mechanism 21 disengages from the first water inlet channel 11 to inject cold water, the guiding component 7 can improve the stability of the transmission assembly 223 and the piston assembly 211, and try to avoid the piston assembly 211 from shaking and generating noise due to the impact of water flow.

[0052] In this embodiment, the mixed water outlet channel 13 includes a first mixing section 131, a second mixing section 132, and a third mixing section 133 that are connected in sequence. Among them, the front end of the first mixing section 131 is connected to the side wall of the valve body module 1. The second water inlet channel 12 is connected to the middle of the first mixing section 131. The sensing end of the sensing module 4 is arranged in the middle of the third mixing section 133. The included angle between the first mixing section 131 and the second mixing section 132 is 90 degrees, and the second mixing section 132 and the third mixing section 133 are arranged in parallel.

[0053] After the cold water injected into the first water inlet channel 11 and the hot water injected into the second water inlet channel 12 converge at the first mixing section 131, the cold water and the hot water flow through the second mixing section 132 and the third mixing section 133 in sequence and then are output. During the process of the water flowing from the first mixing section 131 to the second mixing section 132 and from the second mixing section 132 to the third mixing section 133, the cold water and the hot water can be mixed more fully, thereby improving the uniformity of the hot water output from the mixed water outlet channel 13.

[0054] Implementation principle:

[0055] Under normal conditions, the hot water flows through the second water inlet channel 12 and the mixed water outlet channel 13 in sequence for output;

[0056] When the temperature of the hot water output from the mixed water outlet channel 13 is too high, when the sensing module 4 detects that the temperature of the hot water output from the mixed water outlet channel 13 is higher than the preset temperature value, it feeds back the situation to the control module. The control module controls the output end of the servo module 3 to rotate forward. The output end of the servo module 3 drives the movable component 222 to rotate forward through the cooperation of the clamping post 228 and the clamping groove 229. The movable component 222 moves linearly upward relative to the fixed component 221 through screw cooperation. The movable component 222 also moves linearly upward relative to the output end of the servo module 3. During the process of the movable component 222 moving linearly upward, the piston component 211 is driven to move linearly upward synchronously through the clamping and limiting of the first limiting mechanism 5 and the second limiting mechanism 6, so that the abutting inclined surface of the third sealing ring 212 is separated from the abutting inclined surface of the first water inlet channel 11, thereby realizing that the adjusting mechanism 21 is separated from the first water inlet channel 11, enabling the first water inlet channel 11 to inject cold water. The cold water injected into the first water inlet channel 11 and the hot water injected into the second water inlet channel 12 are mixed and then output by the mixed water outlet channel 13. At this time, the control module controls the operation of the servo module 3 according to the real-time monitoring of the sensing module 4, so that the gap between the adjusting mechanism 21 and the first water inlet channel 11 and the corresponding cold water flow rate are kept within a reasonable range, avoiding discomfort to the user caused by the too high temperature of the hot water output from the mixed water outlet channel 13;

[0057] When the temperature of the hot water output from the mixed water outlet channel 13 is too low, the output end of the servo module 3 drives the movable component 222 to rotate reversely through the cooperation of the clamping post 228 and the clamping groove 229, and the abutting inclined surface of the third sealing ring 212 can be squeezed against the abutting inclined surface of the first water inlet channel 11, thereby realizing that the adjusting mechanism 21 seals the first water inlet channel 11, so that the first water inlet channel 11 cannot inject cold water.

[0058] Embodiment 2:

[0059] The difference between this embodiment and the first embodiment is that this embodiment is further provided with a buffer structure for overloading buffer of the piston assembly 211, and a cleaning structure for real-time cleaning of the first water inlet passage 11.

[0060] In the above, the provided buffer structure is used for overloading buffer of the piston assembly 211, which is specifically manifested in this embodiment as follows:

[0061] Referring to Figures 6-7 , the first limiting mechanism 5 also includes two sets of elastic circlips in the prior art. The two sets of elastic circlips are both clamped in the circlip grooves reserved in the transmission component 223, and the two sets of elastic circlips of the first limiting mechanism 5 are respectively located on the upper and lower sides of the movable component 222, so as to drive the transmission component 223 to move synchronously in a straight line up and down during the straight up and down movement of the movable component 222; the second limiting mechanism 6 specifically includes a mounting block 61, a fixed magnetic part 62, a follower magnetic part 63 and a buffer spring 64. The mounting block 61 is fixedly arranged on the transmission component 223 and is located above the piston assembly 211. Both the fixed magnetic part 62 and the follower magnetic part 63 are made of permanent magnets. The fixed magnetic part 62 is fixedly arranged on the transmission component 223 and is located below the piston assembly 211. The follower magnetic part 63 is fixedly arranged at the bottom of the piston assembly 211. The buffer spring 64 adopts a compression spring structure. The two ends of the buffer spring 64 are respectively fixedly connected between the mounting block 61 and the piston assembly 211. Under the elastic force of the buffer spring 64, the piston assembly 211 always has a tendency to move downward until the fixed magnetic part 62 and the follower magnetic part 63 are in contact with each other.

[0062] When the servo module 3 acts as an external power to drive the transmission component 223 to move upward, the transmission component 223 drives the adjustment mechanism 21 to move upward through the second limit mechanism 6 until it is separated from the first water inlet channel 11. At this time, the buffer spring 64 pushes the piston component 211 to move downward until the fixed magnetic element 62 and the follower magnetic element 63 fit together to form a magnetic attraction effect. Under the dual effects of elastic force and magnetic attraction, the piston component 211 can have good stability and is not prone to up and down shaking, so that the gap size between the adjustment mechanism 21 and the first water inlet channel 11 and the corresponding cold water flow rate have good stability; In other words, when the servo module 3 acts as an external power to drive the transmission component 223 to move downward, the transmission component 223 drives the adjustment mechanism 21 to move downward through the second limiting mechanism 6 until it is blocked in the first water inlet channel 11. At this time, if the servo module 3 over-operates and causes the transmission component 223 to move excessively downward, the fixed magnetic component 62 and the follower magnetic component 63 will be disengaged and the buffer spring 64 will be compressed, so that the transmission component 223 can continue to move downward relative to the adjustment mechanism 21, thereby avoiding excessive extrusion and damage between the third sealing ring 212 of the adjustment mechanism 21 and the first water inlet channel 11 to ensure the stability of the structure. In addition, since the squeezing force between the adjusting mechanism 21 and the first water inlet channel 11 is the sum of the elastic force and the magnetic attraction force, when the transmission component 223 moves excessively downward, the fixed magnetic attraction component 62 and the follower magnetic attraction component 63 are disengaged, and the buffer spring 64 is compressed, the magnetic attraction force exerted on the adjusting mechanism 21 decreases as the transmission component 223 moves downward, and the elastic force exerted on the adjusting mechanism 21 increases as the transmission component 223 moves downward, and the fluctuation of the sum of the elastic force and the magnetic attraction force is relatively small, that is, as the transmission component 223 moves excessively downward, the fluctuation of the squeezing force between the adjusting mechanism 21 and the first water inlet channel 11 is relatively small, thereby avoiding excessive squeezing and damage between the third sealing ring 212 of the adjusting mechanism 21 and the first water inlet channel 11 as much as possible, thereby ensuring the stability of the structure.

[0063] In the above, the cleaning structure is used to clean the first water inlet channel 11 in real time, which is specifically manifested as follows in this embodiment:

[0064] A stirring assembly 8 is provided at a corresponding position of the valve body module 1 inside the first water inlet channel 11, and the stirring assembly 8 is slidably engaged with the transmission assembly 223. A rotating assembly 9 is provided at a corresponding position of the valve body module 1 below the first water inlet channel 11, and when the movable assembly 222 drives the transmission assembly 223 to move linearly to a predetermined position through the first limiting mechanism 5, the rotating assembly 9 drives the stirring assembly 8 to rotate through the transmission assembly 223.

[0065] The stirring assembly 8 specifically includes a sliding ring 81 and a stirring frame 82; wherein, the sliding ring 81 is in a circular ring structure and is sleeved on the transmission assembly 223 in a sliding manner. A transmission block 83 is fixedly arranged on the inner circumference of the sliding ring 81, and a transmission groove 84 that is slidably adapted to the transmission block 83 is arranged on the outer circumference of the transmission assembly 223. The stirring frame 82 is fixedly arranged on the sliding ring 81, and the stirring frame 82 is in contact with the inside of the first water inlet passage 11. Under the support of the stirring frame 82, the sliding ring 81 is in contact with the bottom of the guiding assembly 7.

[0066] Referring to Figures 8-10 , the rotating assembly 9 specifically includes an installation chamber 91, a rotating member 92, a guiding cylinder 93, a thrust rod 94, and a thrust spring 95; wherein, the installation chamber 91 is fixedly arranged at the bottom of the first water inlet passage 11, and the valve body module 1, the first water inlet passage 11, and the installation chamber 91 are coaxially arranged. The bottom end of the transmission assembly 223 penetrates through the fourth sealing ring reserved at the bottom of the first water inlet passage 11 and extends into the installation chamber 91. The rotating member 92 is fixedly arranged at the bottom end of the transmission assembly 223. Four groups of wedge blocks 96 are evenly and fixedly arranged on the outer circumference of the rotating member 92 along its axis. The four groups of wedge blocks 96 are all in a vertical strip-shaped structure, and the bottom ends of the four groups of wedge blocks 96 are 45-degree inclined surfaces; the guiding cylinder 93 is in a cylindrical structure, and the inner diameter of the guiding cylinder 93 is larger than the outer diameter of the rotating member 92. The guiding cylinder 93 is fixedly arranged in the installation chamber 91. Eight groups of avoidance grooves 97 are evenly arranged on the guiding cylinder 93 along its axis. Any avoidance groove 97 is inserted and adapted to any wedge block 96, that is, when the rotating member 92 is inserted into the guiding cylinder 93, the four groups of wedge blocks 96 can be inserted into four of the avoidance grooves 97. In addition, an inclined wedge surface 98 is arranged between two adjacent avoidance grooves 97, and the inclined wedge surface 98 is also a 45-degree inclined surface; the thrust rod 94 is in a hollow round rod structure, and the inner diameter of the guiding cylinder 93 is consistent with the outer diameter of the thrust rod 94. The thrust rod 94 is slidably arranged in the guiding cylinder 93. Eight groups of convex blocks are arranged on the outer circumference of the thrust rod 94, and the eight groups of convex blocks are respectively slidably arranged in the eight groups of avoidance grooves 97 to limit the rotational freedom of the thrust rod 94, so that the thrust rod 94 can only move up and down. Eight groups of guiding teeth 99 are evenly and fixedly arranged on the top of the thrust rod 94 along its axis. The unfolded surface of the guiding teeth 99 is in a right-angled isosceles triangle structure, and the tips of the eight groups of guiding teeth 99 are respectively aligned with the centers of the eight groups of avoidance grooves 97; the thrust spring 95 is in a compression spring structure, and the thrust spring 95 is connected between the installation chamber 91 and the thrust rod 94 to make the thrust rod 94 always have a tendency to move upward until the guiding teeth 99 exceed the inclined wedge surface 98. It is worth mentioning that the sum of the thickness of the guiding teeth 99 and the thickness of the guiding cylinder 93 is equal to the thickness of the wedge block 96, that is, the wedge block 96 can be in contact with the tips of the guiding teeth 99 and the inclined wedge surface 98 simultaneously during the movement process.

[0067] In the initial state, the wedge block 96 is staggered from the avoidance groove 97; when the transmission assembly 223 moves downward to a predetermined position (specifically, since the frictional force between the adjusting mechanism 21 and the first water inlet passage 11 affects the rotation of the transmission assembly 223, the predetermined position means that there is still a gap between the adjusting mechanism 21 and the first water inlet passage 11), the wedge block 96 first contacts the guiding teeth 99, and the wedge block 96 is guided to the bottom of the guiding teeth 99. The transmission assembly 223 continues to move downward, and then the wedge block 96 contacts the wedge surface 98, and the wedge block 96 is guided to completely enter the avoidance groove 97, so that the thrust rod 94 compresses the thrust spring 95; when the transmission assembly 223 moves upward to a predetermined position (specifically, since the frictional force between the adjusting mechanism 21 and the first water inlet passage 11 affects the rotation of the transmission assembly 223, the predetermined position means that there is still a gap between the adjusting mechanism 21 and the first water inlet passage 11), the rotating member 92 moves upward synchronously, the wedge block 96 completely exits the avoidance groove 97, and the thrust rod 94 moves upward under the action of the thrust spring 95 until the guiding teeth 99 exceed the wedge surface 98. At this time, the guiding teeth 99 perform secondary guiding on the wedge block 96, so that the wedge block 96 returns to be staggered from the avoidance groove 97, and this cycle continues.

[0068] In the above process, when the wedge block 96 is guided to the bottom of the guiding teeth 99, when the wedge block 96 is guided to completely enter the avoidance groove 97, and when the guiding teeth 99 perform secondary guiding on the wedge block 96, the rotating member 92 will drive the transmission assembly 223 to rotate in the same direction, and the overall rotation angle is 45 degrees, that is, 1 / 8 of a turn; at this time, during the rotation of the transmission assembly 223, the stirring frame 82 is driven to rotate through the cooperation of the transmission block 83 and the transmission groove 84, so that the stirring frame 82 cleans the inner wall of the first water inlet passage 11 to avoid excessive attachment of impurities as much as possible; since the water flow velocities in different regions of the gap between the adjusting mechanism 21 and the first water inlet passage 11 are different, the wear rates of different regions of the third sealing ring 212 by the impurities in the water flow are also different. In addition, when the transmission assembly 223 rotates, the third sealing ring 212 is driven to rotate by the second limiting mechanism 6, so that different regions of the third sealing ring 212 can continuously rotate and switch to cope with wear, thereby reducing the overall wear rate of the third sealing ring 212.

[0069] This application also discloses an integrated water circuit system with a servo mixing valve.

[0070] Refer to Figures 1-3, An integrated waterway system with a servo mixing valve, including a basic waterway structure 10 and the above-mentioned servo mixing valve. Among them, the basic waterway structure 10 is a common waterway structure in the prior art. For example, a low-position side-insert integrated waterway disclosed by the applicant in CN215809268U will not be elaborated here. The basic waterway structure 10 is provided with a bathroom water inlet interface 101 and a bathroom water outlet interface 102. The second water inlet channel 12 of the servo mixing valve is connected to the bathroom water outlet interface 102, so that the second water inlet channel 12 is connected to the mixed water outlet channel 13 and used to input hot water. The first water inlet channel 11 of the servo mixing valve is connected to the bathroom water inlet interface 101 through a preset connecting pipe 103, so that the first water inlet channel 11 is connected to the bottom of the valve body module 1 and used to input cold water.

[0071] In the application of the wall-mounted boiler waterway system, in the normal state, the hot water heated by the burner circulates in the basic waterway structure 10, and the cold water output by the faucet flows in the basic waterway structure 10 and exchanges heat with the hot water, so as to realize the output of bathroom hot water;

[0072] In a special state where the water pressure of the cold water output by the faucet is small, even if the power of the burner is reduced to the lowest value, due to the too slow flow rate of the cold water in the basic waterway structure 10 and excessive heat exchange with the hot water, the temperature of the bathroom hot water output is too high;

[0073] At this time, when the sensing module 4 detects that the temperature of the hot water output from the mixed water outlet channel 13 is higher than the preset temperature value, it feeds back the situation to the control module. The control module controls the servo module 3 to drive the output end of the transmission mechanism 22 to move upward. The output end of the transmission mechanism 22 drives the adjustment mechanism 21 to move upward to disengage from the first water inlet channel 11, so that part of the cold water of the faucet sequentially passes through the connecting pipe 103 and the first water inlet channel 11 and flows to the second water inlet channel 12, and this part of the cold water is mixed with the hot water and then output by the mixed water outlet channel 13, so as to reduce the temperature of the bathroom hot water; At this time, the control module controls the operation of the servo module 3 according to the real-time monitoring of the sensing module 4, so that the gap between the adjustment mechanism 21 and the first water inlet channel 11 and the corresponding cold water flow rate are kept within a reasonable range, so as to avoid the temperature of the hot water output from the mixed water outlet channel 13 being too high or too low and causing discomfort to the user.

[0074] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
