Description

Technical Field

[0001] This application relates to the field of valve technology, and in particular to a water outlet valve. Background Technology

[0002] The actuators currently installed on the outlet valves of the wall-hung boiler's water circuit module primarily use pin or clip connections. They have axial limit switches but can move freely in the circumferential direction, requiring manual directional control. With the installation of the matching connecting cable, they offer a degree of soft-limit function. However, when the wall-hung boiler is subjected to external forces (such as bumps during transportation), the actuators may shake, posing a risk of the connecting cable coming loose or colliding with other parts.

[0003] Therefore, improving the reliability of the outlet valve is a technical problem that urgently needs to be solved. Utility Model Content

[0004] This application provides a water outlet valve that restricts the actuator's circumferential movement along the axis, reducing the risk of collisions and disconnection of the connecting wires caused by rotation, and improving reliability.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a water outlet valve, including a valve body and an actuator; the valve body is provided with a switching valve chamber, the actuator is mounted on the opening of the switching valve chamber via a base, a switching valve core is coaxially connected to the output shaft of the actuator, and the switching valve core is disposed in the switching valve chamber; a protrusion is provided at the bottom of the actuator housing, and a first limiting mechanism is provided on the base, the first limiting mechanism being used to limit the actuator from rotating relative to the base along the circumference of the actuator.

[0007] The water outlet valve proposed in this application embodiment is designed to prevent the actuator from rotating circumferentially when subjected to external forces such as handling bumps, installation collisions, or pipeline vibrations. The first limiting mechanism can form a rigid constraint circumferentially to directly counteract this rotational tendency, preventing the actuator from shifting circumferentially relative to the base. This ensures that the actuator always remains at the preset installation angle, reducing problems such as loosening of actuator fixing bolts and wire entanglement caused by circumferential rotation. It also reduces the risk of collisions and disconnection of connecting wires caused by rotation. After the first limiting mechanism eliminates circumferential rotation, the relative position of the actuator and the base remains fixed, avoiding unnecessary friction and collisions, reducing component wear rate, improving the overall durability of the water outlet valve, and reducing later maintenance and replacement costs.

[0008] Optionally, the first limiting mechanism includes a first groove along the circumference of the actuator. The first groove includes a first side and a second side disposed opposite to each other, and a protrusion is disposed between the first side and the second side.

[0009] In the above scheme, the first groove can limit the circumferential movement of the protrusion, so that the two work together to restrict the rotation of the actuator. The first side and the second side block the protrusion from two opposite directions. When the actuator is subjected to an external force in the clockwise or counterclockwise direction, the protrusion will be blocked by the corresponding side and cannot produce any circumferential rotation, thereby restricting the rotation of the actuator relative to the base. The constraint is more comprehensive and the reliability is higher.

[0010] Optionally, the base includes a base body and an extension. A portion of the base body is disposed within the switching valve chamber, and the extension is disposed on the outer peripheral surface of the base body and extends radially along the actuator. A first groove is provided on the extension.

[0011] In the above scheme, the base body is fixed in the switching valve chamber, which can provide a stable installation reference for the actuator and avoid problems such as actuator shaking and base seal failure caused by base loosening. This helps to improve the reliability of the outlet valve. This setting not only facilitates the cooperation between the first groove and the protrusion, but also allows the cooperation gap to be controlled within a smaller range, avoiding the limit loosening caused by excessive cooperation gap. At the same time, it can reduce the impact of wear on the groove and protrusion on the sealing performance of the base body and improve reliability.

[0012] Optionally, the first groove includes a first bottom surface along the circumference of the actuator, with the two ends of the first bottom surface connected to a first side surface and a second side surface, respectively, and the first bottom surface being perpendicular to the first side surface and the second side surface.

[0013] In the above scheme, the first side and the second side are arranged opposite each other along the circumference of the actuator to prevent the circumferential rotation of the protrusion. The vertically connected first bottom surface provides stable support for the two sides, preventing the sides from tilting or deforming due to force. This ensures that the first side and the second side always maintain a posture perpendicular to the circumference of the actuator, thereby stably preventing the displacement of the protrusion. At the same time, it facilitates the precise surface-to-surface fit between the first groove and the protrusion, ensuring the accuracy of the circumferential installation angle of the actuator and reducing the impact of assembly errors on the limiting firmness.

[0014] Optionally, the first groove includes a first bottom surface along the circumference of the actuator, with the two ends of the first bottom surface connected to a first side surface and a second side surface, respectively, and at least a portion of the first bottom surface is constructed as an arc surface.

[0015] In the above scheme, the first and second sides connected in the circumferential direction can effectively block the circumferential rotation of the protrusion, while the arc-shaped first bottom surface can disperse and transmit the radial force generated by the vibration along the arc surface instead of concentrating it at a certain point when the actuator has a tendency to move in the circumferential direction. This can effectively weaken the vibration intensity and reduce the probability of vibration being transmitted to the base and the switching valve core, which helps to reduce the vibration noise of the actuator and the base and improve the quietness of the outlet valve operation. At the same time, the fit between the arc-shaped first bottom surface and the protrusion helps to reduce the wear of components caused by hard contact, taking into account both the reliability of the limit and the service life.

[0016] Optionally, the first side includes a first segment and a second segment connected together, and the second side includes a third segment and a fourth segment connected together. The first segment is farther away from the switching valve core than the second segment, and the third segment is farther away from the switching valve core than the fourth segment. Along the circumference of the actuator, the distance between the first segment and the third segment is greater than the distance between the second segment and the fourth segment.

[0017] In the above scheme, the first and third sections can guide the protrusion. During assembly, even if there is a slight deviation in the circumferential alignment between the protrusion and the groove, the larger outer distance allows the protrusion to easily enter between the first and third sections, and then slide along the transition surface of the two-section structure into the second and fourth sections with a smaller inner distance. There is no need to repeatedly calibrate the angle, which reduces the requirements for assembly accuracy and is especially suitable for rapid assembly in mass production.

[0018] Optionally, the distance between the first side and the second side gradually decreases from the opening of the switching valve chamber to the switching valve core.

[0019] In the above scheme, the first side and the second side can jointly clamp the protrusion. The gradually changing spacing helps to disperse stress, reduce the probability of stress concentration caused by the protrusion, and help to improve the overall stability and reliability.

[0020] Optionally, a second limiting mechanism is also provided between the base and the actuator, along the axial direction of the actuator, to limit the movement of the actuator relative to the base.

[0021] In the above scheme, the second limiting mechanism restricts the movement of the actuator along the axial direction, which can ensure that the actuator always stays in the preset axial installation position, reduce the probability of axial sway of the actuator, avoid abnormal contact between the actuator and surrounding components, reduce collision and friction loss, extend the service life of the actuator, switching valve core and related transmission components, and reduce the failure probability of the outlet valve. At the same time, it can ensure that the protrusion is always fully embedded in the first groove, maintain full contact between the protrusion and the side of the groove, and allow the first limiting mechanism to continuously play a stable circumferential limiting role, thereby more comprehensively suppressing the multi-directional displacement of the actuator and making the overall installation of the actuator more stable.

[0022] Optionally, the protrusion includes two first limiting protrusions, and the first limiting mechanism includes two second limiting protrusions. The two first limiting protrusions are disposed on the actuator, and the two second limiting protrusions are disposed on the base. Along the circumference of the actuator, the two first limiting protrusions are located between the two second limiting protrusions and respectively abut against the corresponding second limiting protrusions.

[0023] In the above scheme, on the one hand, it is convenient to flexibly adjust the position of the protrusion, which helps to improve the structural compactness; on the other hand, it facilitates stress dispersion, significantly reducing the wear rate and deformation risk of the protrusion. In addition, it reduces the cumbersome installation process when the protrusion and the groove are matched, improving the ease of use. When the actuator has a clockwise rotation tendency, the first limiting protrusion near the clockwise direction will rigidly abut against the corresponding second limiting protrusion to prevent displacement. When there is a counterclockwise rotation tendency, the first limiting protrusion and the second limiting protrusion on the other side rigidly abut against the displacement, thereby improving reliability.

[0024] Optionally, the base includes a base body partially disposed within the switching valve chamber, and the first limiting mechanism includes two limiting blocks disposed on the outer peripheral surface of the base body and extending radially along the actuator.

[0025] Two limiting blocks are spaced apart along the circumference of the actuator, and the protrusion is sandwiched between the two limiting blocks.

[0026] In the above solution, the protrusion of the actuator can be matched with the two limit blocks by setting the interval between them. The processing technology is simple and the cost is lower. During assembly, the protrusion can be placed in the gap between the two limit blocks without repeated calibration of the circumferential angle, which greatly improves the assembly efficiency. The two limit blocks clamp the protrusion by the circumferential interval, which can directly form a rigid circumferential constraint on the actuator and improve the overall reliability.

[0056] The actuators currently installed on the outlet valves of the wall-hung boiler's water circuit module primarily use pin or clip connections. They have axial limit switches but can move freely in the circumferential direction, requiring manual directional control. With the installation of the matching connecting cable, they offer a degree of soft-limit function. However, when the wall-hung boiler is subjected to external forces (such as bumps during transportation), the actuators may shake, posing a risk of the connecting cable coming loose or colliding with other parts.

[0057] Therefore, in order to reduce the probability of actuator 400 shaking and improve the reliability of the outlet valve, this application provides an outlet valve. The bottom of the actuator 400 housing has a protrusion 410, and the base 300 has a first limiting mechanism 500. Along the circumference of the actuator 400, the first limiting mechanism 500 is used to limit the rotation of the actuator 400 relative to the base 300. It can be understood that the first limiting mechanism 500 can limit the rotation of the actuator 400. When the actuator 400 shakes due to external forces such as handling, installation collisions, or pipeline vibration... The actuator 400 is prone to radial offset and rotation. The first limiting mechanism 500 can form a rigid constraint along the circumference of the actuator 400 to counteract the circumferential rotation tendency caused by external forces, reduce the probability of the actuator 400 offset and wobbling due to external forces, reduce the risk of collision and pull-out of connecting lines caused by rotation, ensure that the relative position of the actuator 400 and the surrounding components remains fixed, avoid unnecessary friction and collision, reduce component wear, reduce the probability of failure caused by external forces, significantly improve the overall durability and reliability of the outlet valve, and reduce the later maintenance cost.

[0058] The water outlet valve proposed in the embodiments of this application is described below with reference to the accompanying drawings.

[0059] Please refer to Figure 1 and Figure 2 According to the first aspect of this application, the outlet valve includes a valve body 100 and an actuator 400.

[0060] A switching valve chamber 100a is provided on the valve body 100. The actuator 400 is installed at the opening of the switching valve chamber 100a via the base 300. A switching valve core 200 is coaxially connected to the output shaft of the actuator 400. The switching valve core 200 is located inside the switching valve chamber 100a. It can be understood that the valve body 100, as the main structure of the outlet valve, can provide a fixed installation space for the switching valve core 200 in the switching valve chamber 100a. The switching valve core 200, located inside the switching valve chamber 100a, can play the role of controlling the on / off of water outlet and regulating the flow rate.

[0061] Meanwhile, the base 300 can serve as a mounting base for the actuator 400, which can fix the actuator 400 to the valve body 100. As an example, the base 300 and the valve body 100 can be fixed by the cooperation of the pin 610 and the pin groove 620, or by bolt connection or snap-fit. This application does not limit this.

[0062] After the base 300 is fixed to the valve body 100, it can isolate the actuator 400 and the switching valve core 200, preventing liquid from entering the actuator 400 or preventing impurities from entering the switching valve chamber 100a. At the same time, the switching valve core 200 can pass through the base 300 and be driven by the actuator 400, and the actuator 400 can act as a driving component to drive the switching valve core 200.

[0063] When the outlet valve is subjected to external force, the valve body 100 and the base 300 can act as a whole to resist the impact and vibration of the external force, thereby helping to reduce the probability of the external force being transmitted to the actuator 400.

[0064] The intermediate isolation function of the base 300 prevents direct contact between the actuator 400 and the switching valve core 200. On the one hand, slight vibrations that may occur during the operation of the actuator 400 will not be directly transmitted to the switching valve core 200, reducing the occurrence of poor sealing or jamming of the switching valve core 200 due to vibration. On the other hand, if a small amount of leakage occurs in the medium in contact with the switching valve core 200, the base 300 can prevent it from directly entering the interior of the actuator 400, avoiding short circuits and damage to the actuator 400, and ensuring the operational safety of the actuator 400.

[0065] In addition, arranging the base 300, actuator 400, and switching valve core 200 along the axial direction of actuator 400 can avoid excessive radial space occupation by each component, making the overall structure of the outlet valve more compact.

[0066] The bottom of the housing of the actuator 400 is provided with a protrusion 410. It can be understood that the actuator 400 has a cam rotation structure inside, and the cam rotation structure protrudes outward along the radial direction of the output shaft. That is to say, the protrusion 410 can be part of the actuator 400 itself, and can provide movement space and accommodation space for the internal components of the actuator 400. The protrusion 410 is limited by the shape of the actuator mechanism inside the actuator 400 and varies. This application does not limit the shape of the protrusion 410.

[0067] Meanwhile, the actuator 400 housing is mostly injection molded or die-cast, and the protrusion 410 is integrally formed with the actuator 400 housing.

[0068] The base 300 is equipped with a first limiting mechanism 500 along the circumference of the actuator 400. The first limiting mechanism 500 is used to limit the rotation of the actuator 400 relative to the base 300. It is understood that when the outlet valve encounters external forces such as handling bumps, installation collisions, or pipeline vibrations, the actuator 400 is prone to rotation along the circumference. The first limiting mechanism 500 can form a rigid constraint along the circumference, directly counteracting this rotational tendency, preventing the actuator 400 from shifting circumferentially relative to the base 300, ensuring that the actuator 400 always remains at the preset installation angle, reducing the occurrence of problems such as loosening of the actuator 400 fixing bolts and wire entanglement caused by circumferential rotation, and reducing the risk of collisions and pull-out of connecting wires caused by rotation.

[0069] As an example, the first limiting mechanism 500 can be a boss and groove mating structure or a positioning pin and positioning hole mating structure, and this application does not limit it in this way.

[0070] Meanwhile, when the actuator 400 rotates circumferentially, its housing and output shaft will experience abnormal friction with the mounting holes and surrounding connecting parts of the base 300. Over time, this will exacerbate component wear and may even lead to increased clearance and increased vibration. After the first limit mechanism 500 eliminates circumferential rotation, the relative position of the actuator 400 and the base 300 remains fixed, avoiding unnecessary friction and collision, reducing component wear rate, improving the overall durability of the outlet valve, and reducing later maintenance and replacement costs.

[0071] In other embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The first limiting mechanism 500 includes a first groove 520. It can be understood that the first groove 520 can limit the circumferential movement of the protrusion 410, so that the two work together to limit the rotation of the actuator 400.

[0072] In addition, the first groove 520 does not require complex machining and can be integrally formed during the injection molding and die casting process of the base 300, reducing manufacturing costs and process difficulty. During installation, the protrusion 410 is simply aligned with the first groove 520 and inserted to complete circumferential positioning without the need for additional calibration tools, which can significantly improve assembly efficiency.

[0073] Meanwhile, the plug-in fit can form a clear installation benchmark, ensuring that the actuator 400 can maintain a consistent circumferential angle every time it is installed, which helps to improve assembly accuracy.

[0074] Along the circumference of the actuator 400, the first groove 520 includes a first side surface 521 and a second side surface 522 disposed opposite to each other, and a protrusion 410 disposed between the first side surface 521 and the second side surface 522. It is understood that the first side surface 521 and the second side surface 522 respectively block the protrusion 410 from two opposite directions. When the actuator 400 is subjected to an external force in a clockwise or counterclockwise direction, the protrusion 410 will be blocked by the corresponding side surface, preventing any circumferential rotation, thus restricting the actuator 400's rotation relative to the base 300. This provides more comprehensive constraint and higher reliability. When the actuator 400 is subjected to a circumferential force, the circumferential force will be distributed through the protrusion 410 to the first side surface 521 and the second side surface 522 of the first groove 520, avoiding component deformation or wear caused by excessive force at a single point.

[0075] In addition, when the first groove 520 is provided on the base 300, the position of the groove can be planned using the structural margin of the base 300, such as the outer peripheral surface or end face. This arrangement facilitates processing and helps to improve the overall structural compactness.

[0076] In other embodiments, please refer to Figure 1 and Figure 2 The base 300 includes a base body 310 and an extension 320. Part of the base body 310 is disposed within the switching valve chamber 100a. This arrangement serves two purposes: firstly, it separates the switching valve core 200 from the actuator 400, ensuring the sealing of the valve body 100 and preventing leakage from the outlet valve; secondly, the base body 310, fixed within the valve body 100, provides a stable mounting reference for the actuator 400, preventing problems such as actuator 400 shaking or base 300 sealing failure due to loosening of the base 300, thus helping to improve the reliability of the outlet valve.

[0077] The extension 320 is disposed on the outer peripheral surface of the base body 310 and extends radially along the actuator 400. This arrangement avoids the water flow channel inside the valve body 100 and the movement trajectory of the switching valve core 200, and reduces obstruction to the axial installation space of the actuator 400. It does not affect the axial alignment of the actuator 400 and the switching valve core 200, and facilitates the connection between the output shaft of the actuator 400 and the switching valve core 200. It also solves the problem of spatial conflict between the first limiting mechanism 500 and other components.

[0078] The extension 320 is provided with a first groove 520. It can be understood that the first groove 520 on the extension 320 can cooperate with the protrusion 410 on the outer surface of the actuator 400, thereby playing a role in circumferentially limiting the actuator 400. This design not only facilitates the cooperation between the first groove 520 and the protrusion 410, but also allows the cooperation gap to be controlled within a smaller range, avoiding loosening of the limit due to excessive cooperation gap. At the same time, it can reduce the impact of wear on the first groove 520 and the protrusion 410 on the sealing performance of the base body 310, thereby improving reliability.

[0079] In other embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The first groove 520 includes a first bottom surface 523 along the circumference of the actuator 400. The two ends of the first bottom surface 523 are connected to a first side surface 521 and a second side surface 522, respectively. The first bottom surface 523 is perpendicular to both the first side surface 521 and the second side surface 522. It can be understood that the first side surface 521 and the second side surface 522 are arranged opposite each other along the circumference of the actuator 400 to prevent the circumferential rotation of the protrusion 410. The perpendicularly connected first bottom surface 523 provides stable support for the two sides, preventing them from tilting or deforming due to force, and ensuring that the first side surface 521 and the second side surface 522 always maintain a posture perpendicular to the circumference of the actuator 400, thereby stably preventing the displacement of the protrusion 410.

[0080] At the same time, it facilitates the precise surface-to-surface fit between the first groove 520 and the protrusion 410, ensuring the stability of the circumferential and radial positions of the protrusion 410 within the first groove 520, reducing the occurrence of protrusion 410 offset, ensuring the accuracy of the circumferential installation angle of the actuator 400, and reducing the impact of assembly errors on the limiting firmness.

[0081] In addition, the vertical connection allows the connection between the first bottom surface 523 and the two sides to be subjected to more even force. When the protrusion squeezes the side, the force will be directly transmitted to the bottom surface in the vertical direction, reducing the occurrence of stress concentration at the connection corner, improving the fatigue resistance of the first groove 520, and extending the reliability after long-term use.

[0082] In other embodiments, please refer to Figure 5The first groove 520 includes a first bottom surface 523 along the circumference of the actuator 400. The two ends of the first bottom surface 523 are connected to the first side surface 521 and the second side surface 522 respectively. At least a portion of the first bottom surface 523 is constructed as an arc surface. It can be understood that the circumferentially connected first side surface 521 and second side surface 522 can effectively block the circumferential rotation of the protrusion 410. The arc-shaped first bottom surface 523 can disperse the radial force generated by the vibration along the arc surface when the actuator 400 has a tendency to move circumferentially, rather than concentrating it at a certain point. This can effectively weaken the vibration intensity, reduce the probability of vibration being transmitted to the base 300 and the switching valve core 200, and prevent the switching valve core 200 from experiencing poor sealing or jamming due to vibration. At the same time, it reduces the vibration noise of the actuator 400 and the base 300, and improves the quietness of the outlet valve operation.

[0083] Meanwhile, the contact between the arc-shaped first bottom surface 523 and the protrusion 410 helps to reduce component wear caused by hard contact, balancing the reliability of the limit and the service life.

[0084] In other embodiments, please refer to Figure 6 The first side 521 includes a first segment 521a and a second segment 521b connected together, and the second side 522 includes a third segment 522a and a fourth segment 522b connected together. It can be understood that the first segment 521a and the second segment 521b can work together to prevent the protrusion 410 from moving circumferentially, and the third segment 522a and the second segment 521b can work together to prevent the protrusion 410 from moving circumferentially. The segmented design makes it easy for the first side 521 and the second side 522 to adjust their circumferential dimensions according to actual needs, thereby improving ease of use.

[0085] The first segment 521a is farther away from the switching valve core 200 than the second segment 521b, and the third segment 522a is farther away from the switching valve core 200 than the fourth segment 522b. In other words, the first segment 521a is located at the end of the first side 521 that is farther away from the switching valve core 200, and the third segment 522a is located at the end of the second side 522 that is farther away from the switching valve core 200. This facilitates the guidance of the protrusion when assembling the actuator 400 and improves the ease of use.

[0086] Along the circumference of actuator 400, the distance between the first segment 521a and the third segment 522a is greater than the distance between the second segment 521b and the fourth segment 522b. Understandably, the greater circumferential distance between the first segment 521a and the third segment 522a compared to the second segment 521b and the fourth segment 522b creates a flared structure. The first segment 521a and the third segment 522a can guide the protrusion 410. During assembly, even if there is a slight misalignment between the protrusion 410 and the groove in the circumferential direction, the larger outer distance allows the protrusion 410 to easily enter between the first segment 521a and the third segment 522a, and then slide along the transition surface of the two-segment structure into the smaller inner distance between the second segment 521b and the fourth segment 522b. This eliminates the need for repeated angle calibration, reduces the requirements for assembly accuracy, and is particularly suitable for rapid assembly in mass production.

[0087] In other embodiments, please refer to Figure 1 and Figure 9 From the opening of the switching valve chamber 100a to the switching valve core 200, the distance between the first side 521 and the second side 522 gradually decreases. It can be understood that the first side 521 and the second side 522 can jointly clamp the protrusion 410. The gradually changing spacing helps to disperse stress, reduce the probability of stress concentration caused by the protrusion 410, and help improve overall stability and reliability.

[0088] Meanwhile, the gradient side spacing design between the first side 521 and the second side 522 can play a natural guiding role during the assembly of the protrusion 410, so that the protrusion 410 can be smoothly inserted into the first groove 520 without repeated precise calibration, effectively reducing the assembly difficulty and improving the assembly efficiency.

[0089] As an example, the first groove 520 can be U-shaped, V-shaped, arc-shaped or other shapes, and this application does not limit it.

[0090] In other embodiments, please refer to Figure 1 and Figure 7 A second limiting mechanism 600 is also provided between the base 300 and the actuator 400. Along the axial direction of the actuator 400, the second limiting mechanism 600 is used to limit the movement of the actuator 400 relative to the base 300. It can be understood that by limiting the movement of the actuator 400 along the axial direction, the second limiting mechanism 600 can ensure that the actuator 400 is always kept in the preset axial installation position, so that the docking depth and fit clearance between the output shaft of the actuator 400 and the transmission structure of the switching valve core 200 are stable over a long period of time, avoiding power transmission deviation caused by axial displacement, and ensuring that the switching valve core 200 can accurately respond to the control command of the actuator 400 with each action, maintaining the normal opening and closing and flow regulation functions of the outlet valve.

[0091] Meanwhile, during transportation, installation, or use, the outlet valve may encounter axial impacts, such as bumps during handling or axial forces transmitted by pipeline vibration. If the actuator 400 lacks axial limiting, it is prone to repeated axial wobbling. The second limiting mechanism 600, by axially fixing the actuator 400, can reduce the probability of axial wobbling of the actuator 400, avoid abnormal contact between the actuator 400 and surrounding components, reduce collision and friction losses, extend the service life of the actuator 400, the switching valve core 200, and related transmission components, reduce the failure probability of the outlet valve, and improve reliability.

[0092] This design reduces the likelihood of frequent collisions between the actuator 400 and surrounding components. On the one hand, it reduces the chance of hard impacts between the actuator 400 housing and the base 300 extension 320 or the top of the valve body 100, preventing wear, deformation, or even damage to the internal windings of the actuator 400. On the other hand, it reduces wear on the output shaft bearing and the transmission components of the switching valve core 200, thus improving the service life of the components.

[0093] In addition, after the second limiting mechanism 600 restricts the axial movement of the actuator 400, it can ensure that the protrusion 410 is always fully embedded in the first groove 520, maintain full contact between the protrusion 410 and the side of the groove, and allow the first limiting mechanism 500 to continuously play a stable circumferential limiting role, thereby more comprehensively suppressing the multi-directional displacement of the actuator 400 and making the overall installation of the actuator 400 more stable.

[0094] In other specific embodiments, please refer to Figure 1 and Figure 7 The second limiting mechanism 600 includes a pin 610 and a pin slot 620 that are inserted and mated. The pin slot 620 is disposed on the actuator 400, and the pin 610 is disposed on the base 300. It can be understood that the pin slot 620 can be directly integrally formed on the housing of the actuator 400. After the pin 610 is inserted into the pin slot 620, it can accurately limit the axial movement of the actuator 400. Furthermore, the pin 610 is easy to insert and remove, thus improving the ease of use.

[0095] As an example, the base body 310 has a second slot that can accommodate the pin 610. The pin 610 can be used to snap the actuator 400 onto the base body 310 through the second slot and the pin slot 620, which improves the connection strength. During assembly, the pin 610 can be inserted simply by ensuring that the axial position of the actuator 400 is in the preset position, which improves the ease of use.

[0096] Along the axial direction of the actuator 400, the pin slot 620 includes a third side 621 and a fourth side 622 disposed opposite to each other, with the pin 610 disposed between the third side 621 and the fourth side 622. It can be understood that, along the axial direction of the actuator 400, the third side 621 and the fourth side 622 correspond to two directions of axial movement of the actuator 400, respectively. The third side 621 can prevent the actuator 400 from moving upward, and the fourth side 622 can prevent the actuator 400 from moving downward. After the pin 610 is placed between the two, when the actuator 400 is subjected to an external force and tends to move upward, the pin 610 will rigidly abut against the third side 621; when it tends to move downward, the pin 610 will contact the fourth side 622, forming a bidirectional stop, which can completely block the bidirectional axial displacement of the actuator 400 and improve overall stability.

[0097] In other embodiments, please refer to Figure 8 The protrusion 411 includes two first limiting protrusions 411, and the first limiting mechanism 500 includes two second limiting protrusions 540. The two first limiting protrusions 411 are disposed on the actuator 400, and the two second limiting protrusions 540 are disposed on the base 300. It can be understood that the outer shell of the actuator 400 is mostly a regular cylindrical or rectangular shape, and the first limiting protrusions 411 can be symmetrically distributed rectangular protrusions and integrally formed using the flat surface of the outer shell. The first limiting protrusions 411 can provide moving space or accommodating space for the components inside the actuator 400.

[0098] Along the circumference of the actuator 400, two first limiting protrusions 411 are located between two second limiting protrusions 540 and abut against their respective second limiting protrusions 540. It can be understood that, viewed circumferentially, the two second limiting protrusions 540 can provide continuous circumferential constraint on the first limiting protrusions 411. When the actuator 400 tends to rotate clockwise, the first limiting protrusion 411 closer to the clockwise direction will rigidly abut against the corresponding second limiting protrusion 540 to prevent displacement; when there is a counterclockwise rotation tendency, the first limiting protrusion 411 and the second limiting protrusion 540 on the other side rigidly abut against each other to prevent displacement, thereby improving reliability.

[0099] In other embodiments, please refer to Figure 1 and Figure 10 The base 300 includes a base body 310 partially disposed within the switching valve chamber 100a, and the first limiting mechanism 500 includes two limiting blocks 330 disposed on the outer peripheral surface of the base body 310 and extending radially along the actuator 400.

[0100] Along the circumference of the actuator 400, two limit blocks 330 are spaced apart, and a protrusion 410 is sandwiched between the two limit blocks 330.

[0101] In the above scheme, the two limiting blocks 330 clamp the protrusion 410 at circumferential intervals, which can directly form a rigid circumferential constraint on the actuator 400. When the actuator 400 tends to rotate clockwise or counterclockwise due to transportation bumps or pipeline vibration, the protrusion 410 will be directly blocked by the limiting block 330 on the corresponding side, effectively avoiding circumferential displacement of the actuator 400, fundamentally reducing the risk of the connecting line being pulled off or colliding with surrounding parts due to rotation, and improving the reliability of the water outlet valve.

[0102] Meanwhile, the limiting block 330 is set on the outer peripheral surface of the base body 310 and extends radially. It can avoid the water flow channel in the switching valve chamber 100a and the movement trajectory of the switching valve core 200, so as not to affect the on / off and flow regulation functions of the outlet valve. It can also provide a stable support for the limiting block 330 by utilizing the stable assembly relationship between the base body 310 and the switching valve chamber 100a, so as to prevent the limiting mechanism from failing due to the loosening of the base.

[0103] Furthermore, this structure does not require complex groove processing. It can cooperate with the protrusion 410 of the actuator 400 simply by setting the interval between the two limit blocks 330. The processing technology is simple and the cost is lower. During assembly, you only need to align the protrusion 410 with the gap between the two limit blocks 330 and put it in. There is no need to repeatedly calibrate the circumferential angle, which greatly improves the assembly efficiency.

[0104] The clamping engagement between the limiting block 330 and the protrusion 410 is a surface contact, which can disperse the circumferential force on the actuator and reduce single-point wear. Furthermore, the limiting block 330 is far away from the sealing area of ​​the base body. Even if slight wear occurs after long-term use, it will not affect the sealing performance of the base body 310 and the switching valve chamber 100a, further ensuring the long-term stable operation of the outlet valve.
