Description

Technical Field

[0001] This utility model relates to the field of valve core switch technology, and more specifically, to a rotary flow regulating and push-button switch valve and a water outlet device. Background Technology

[0002] In existing flow valves, flow is generally regulated by a rotary regulating mechanism or opened and closed by a push-button switch. While a single-function rotary valve can finely regulate flow, it usually requires continuous rotation to maintain water output, and a push-button valve can quickly switch on and off, but its flow regulation capability is weak or it requires additional structural support.

[0003] To address this, while effectively integrating these two functions is possible, current functional valves combine the rotary adjustment mechanism and the push-button switch onto the same valve core. This results in a complex structure, high precision requirements for component fit, and increased assembly steps, leading to inconvenient maintenance. Furthermore, detachable rotating parts may experience axial displacement or detachment during prolonged use or under stress, affecting reliability. In particular, rigid contact between structural components results in high rotational resistance, making operation and adjustment laborious, prone to wear, and limiting lifespan. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a rotary flow regulating valve and a press-to-switch valve and a water outlet device to solve the above problems.

[0005] The present invention adopts the following solution:

[0006] This application provides a rotary flow regulating and push-button switch valve, including a valve body, a valve core, a gland, a rotary switch, and a push-button switch; the valve body has a water inlet passage and at least one water outlet communicating with the water inlet passage; the valve core is correspondingly installed on the water inlet passage; the gland is used to install and limit the valve core in its position controlling the water outlet; the rotary switch includes a sleeve fitting around the outer periphery of the valve core, and a rotating component detachably connected between the valve core and the sleeve fitting; the rotating component can operably rotate the valve core to adjust the flow rate; the push-button switch includes an on / off switch. The switch button is connected to the valve core and has a pressed state and a reset state. In the pressed state, the switch button triggers the valve core to open to connect the outlet and the inlet passage. In the reset state, the switch button triggers the valve core to close to disconnect the outlet and the inlet passage. A retaining spring and a friction-reducing ring are also provided between the rotating part and the sleeve part. The retaining spring is sleeved on the end side of the rotating part to restrict the rotating part from detaching from the sleeve part. The friction-reducing ring is fitted between the rotating part and the sleeve part to reduce the friction force of the rotating part during rotation.

[0007] As a further improvement, the retaining ring is in the shape of a C-ring, and a groove adapted to the retaining ring is opened on the end side of the rotating part.

[0008] As a further improvement, the end side of the rotating component is pin-shaped, and the retaining spring protrudes from the outer surface of the end side for locking into the sleeve component in the disengagement direction.

[0009] As a further improvement, the sleeve is provided with a raised inner wall that is adapted to be inserted into the end side of the rotating part, and the lower side of the raised inner wall and the upper side of the retaining spring form an assembly space for the friction-reducing ring.

[0010] As a further improvement, a space for insertion of the rotating component is formed between the valve core and the raised inner wall, and one end of the sleeve is smoothly connected to the rotating component, while the other end of the sleeve is screwed to the pressure cap.

[0011] As a further improvement, the valve core is a Neoper valve, which has a pressing part and a rotating part; the switch button is connected to the pressing part for pressing or resetting the pressing part; the rotating part is connected to the rotating part for rotating the rotating part.

[0012] As a further improvement, the switch button is connected to the pressing part by a double-headed bolt and is installed inside the rotating part without rotating with it.

[0013] As a further improvement, the valve body is provided with a mixing chamber that connects to the water inlet passage, and two valve cores and their respective rotary switches and push switches are arranged side by side in the mixing chamber. The valve body is provided with an upper water outlet that cooperates with one of the valve cores and a lower water outlet that cooperates with the other valve core.

[0014] As a further improvement, the lower outlet has at least multiple water outlet passages.

[0015] This application also provides a water outlet device, including the aforementioned rotary flow regulating and push-button switch valve.

[0016] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0017] 1. The rotary flow regulating and push-button switch valve of this application has a valve core that serves as both the rotary regulating actuator and the push-button opening and closing actuator. Users can adjust the required flow rate by rotating the actuator, or quickly open and close the valve core by using the switch button. The two functions do not interfere with each other, and the operation is intuitive and flexible. The detachable and modular design of the sleeve and the rotating actuator facilitates assembly and maintenance, greatly reducing production and maintenance costs.

[0018] 2. The retaining ring at the end of the rotating part can fit and limit the axial displacement of the rotating part, effectively preventing the rotating part from disengaging from the sleeve when vibrating or under stress, ensuring the structural integrity and safety of long-term use. In addition, the anti-friction ring between the rotating part and the sleeve reduces the frictional torque during relative rotation, making the adjustment smoother, the operating torque smaller, reducing wear, extending service life, and improving the user experience.

[0019] 3. The gland is used to fix the valve core in the position to control the water outlet, ensuring stable valve core positioning and reliable sealing, reducing leakage risk and maintaining the accuracy of the water flow setting. The valve body is equipped with a water inlet passage and at least one water outlet, which is suitable for various water circuit layouts. The overall structure facilitates integration into various faucets, shower heads or water outlet pipes. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0027] Example

[0028] Combination Figures 1 to 5 This embodiment provides a rotary flow regulating and push-button switch valve, including a valve body 1, a valve core 2, a pressure cap 3, a rotary switch, and a push-button switch. The valve body 1 has a water inlet passage and at least one water outlet communicating with the water inlet passage. The valve core 2 is correspondingly installed on the water inlet passage. The pressure cap 3 is used to install and limit the valve core 2 in its position controlling the water outlet.

[0029] The rotary switch includes a sleeve 4 fitted around the outer periphery of the valve core 2, and a rotating component 5 detachably connected between the valve core 2 and the sleeve 4. The rotating component 5 can operably rotate the valve core 2 to adjust the flow rate.

[0030] The push-button switch includes a switch button 6, which is connected to the valve core 2. It has a pressed state and a reset state. In the pressed state, the switch button 6 is used to trigger the valve core 2 to open to connect the water outlet and the water inlet passage. In the reset state, the switch button 6 is used to trigger the valve core 2 to close to disconnect the water outlet and the water inlet passage.

[0031] A retaining spring 7 and a friction-reducing ring 8 are also provided between the rotating component 5 and the sleeve component 4. The retaining spring 7 is sleeved on the end side of the rotating component 5 to restrict the rotating component 5 from detaching from the sleeve component 4. The friction-reducing ring 8 is fitted between the rotating component 5 and the sleeve component 4 to reduce the friction force of the rotating component 5 during rotation.

[0032] In the above, the valve core 2 serves as both the actuator for rotary adjustment and the passive component for press-to-open and close. Users can adjust the required flow rate by rotating the component 5, or quickly open and close the valve core 2 by using the switch button 6. The two functions do not interfere with each other, making the operation intuitive and flexible. The detachable and modular design of the sleeve component 4 and the rotating component 5 facilitates assembly and maintenance, greatly reducing production and maintenance costs.

[0033] The retaining ring 7 provided at the end of the rotating part 5 can fit and limit the axial displacement of the rotating part 5, effectively preventing the rotating part 5 from disengaging from the sleeve part 4 when vibrating or under stress, ensuring the structural integrity and safety of long-term use. In addition, the friction-reducing ring 8 provided between the rotating part 5 and the sleeve part 4 reduces the friction torque during relative rotation, making the adjustment smoother, the operating torque smaller, reducing wear, extending service life, and improving the user experience.

[0034] The gland 3 is used to fix the valve core 2 in the position of controlling the water outlet, ensuring that the valve core 2 is stably positioned and reliably sealed, reducing the risk of leakage and maintaining the accuracy of the water flow setting. The valve body 1 is provided with a water inlet passage and at least one water outlet, which is suitable for various water circuit layout scenarios. The overall structure is easy to integrate into various faucets, shower heads or water outlet pipes.

[0035] like Figures 2 to 4 As shown, in this embodiment, the retaining ring 7 is C-shaped, and a groove adapted to the retaining ring 7 is correspondingly provided on the end side of the rotating member 5. Obviously, the C-shaped retaining ring 7 and the groove of the rotating member 5 cooperate to form a locking structure, which can reliably limit the position of the rotating member 5 in the axial direction, prevent the rotating member 5 from axially dislodging under force, vibration or repeated operation, improve the overall reliability and safety, and play a role in achieving a tighter fit during the assembly and disassembly of the rotating member 5 relative to the sleeve member 4.

[0036] Specifically, the end of the rotating component 5 is pin-shaped, and the retaining spring 7 protrudes from its outer surface to engage within the sleeve component 4 in the disengagement direction. Thus, the pin-shaped end provides better guidance and less resistance when inserted into the sleeve component 4, and the retaining spring 7 automatically ejects and engages in the disengagement direction after passing through the inner cavity of the sleeve component 4, achieving unidirectional press-fit assembly. Furthermore, the retaining spring 7 engaging within the sleeve component 4 in the disengagement direction effectively restricts the axial displacement of the rotating component 5, preventing it from disengaging under vibration, impact, or repeated operation, thereby improving structural safety and long-term reliability.

[0037] Furthermore, the sleeve 4 has a corresponding protruding inner wall 9 that is adapted to fit the end of the rotating member 5, and the lower side of the protruding inner wall 9 and the upper side of the retaining spring 7 form an assembly space for the friction-reducing ring 8. This allows the friction-reducing ring 8 to be fixed in the assembly space, preventing displacement or extrusion during assembly or use, ensuring the friction-reducing element remains in an effective working position for a long time. Moreover, the friction ring, confined within this assembly space, functions stably, significantly reducing sliding friction between the rotating member 5 and the sleeve 4, resulting in smoother flow regulation, lower operating torque, and improved user feel.

[0038] In this design, a space is formed between the valve core 2 and the raised inner wall 9 for the insertion of the rotating component 5. One end of the sleeve 4 smoothly engages with the rotating component 5, while the other end of the sleeve 4 is screwed onto the pressure cap 3. On one hand, the insertion space and smooth engagement ensure accurate positioning of the rotating component 5 in the radial and axial directions, guaranteeing coaxial cooperation between the rotating component 5, the valve core 2, and the sleeve 4. This improves the transmission efficiency and stability of the rotation, and reduces wear and noise caused by eccentricity. On the other hand, the reserved insertion space between the valve core 2 and the raised inner wall 9 allows the rotating component 5 to be assembled or pre-installed as an independent module before the sleeve and pressure cap are screwed together, simplifying the assembly process and improving production capacity and assembly consistency.

[0039] In this embodiment, the valve core 2 is a Neoper valve, which has a pressing part and a rotating part (not shown). The switch button 6 is connected to the pressing part and is used to press or reset the pressing part. The rotating part 5 is connected to the rotating part and is used to rotate the rotating part. It should be mentioned that the Neoper valve, as an existing and mature valve core 2 product, has a good foundation in terms of sealing performance, wear resistance, and lifespan, directly improving the reliability and durability of the entire machine. Since the pressing part and rotating part inside the valve core 2 have independent functions, the switch button 6 only controls the opening and closing action, and the rotating part 5 is only responsible for flow regulation; the two do not interfere with each other, improving ease of use.

[0040] The switch button 6 is connected to the pressing part by a double-ended bolt 10 and is installed inside the rotating part 5 without rotating with it. The double-ended bolt 10 rigidly fixes the switch button 6 to the pressing part of the valve core 2, so that the switch button 6 remains stationary when the rotating part 5 rotates. The pressing switch action and the rotation adjustment action are independent of each other, avoiding misoperation or unstable feel caused by the movement of the rotating part 5 when the user presses the button.

[0041] In this embodiment, the valve body 1 is provided with a mixing chamber 11 connected to the water inlet passage. Two valve cores 2, along with their respective rotary and push-button switches, are arranged side-by-side within the mixing chamber 11. The valve body 1 has an upper outlet 12 that cooperates with one of the valve cores 2 and a lower outlet 13 that cooperates with the other valve core 2. Water first enters the mixing chamber 11 to mix hot and cold water. The two parallel valve cores 2 obtain water from the same mixing chamber 11, ensuring consistent water temperature and quality at the upper and lower outlets 13, avoiding temperature or quality differences caused by independent water intake. Furthermore, each valve core 2 is equipped with a rotary adjustment and a push-button switch, allowing independent setting and opening of either the upper outlet 12 or the lower outlet 13. Users can use one outlet individually or simultaneously open both outlets as needed, providing greater flexibility.

[0042] Preferably, the lower water outlet 13 has at least multiple water outlet passages. Thus, the multiple water outlet passages can be configured with different types of nozzles or water outlets, facilitating the achievement of various spraying effects from the same lower water outlet 13 to meet different usage scenarios.

[0043] In addition, this embodiment provides another water outlet device, including the aforementioned rotary flow regulating valve and push-button switch valve. Integrating the rotary flow regulating valve and push-button switch valve into the water outlet device not only retains and amplifies the advantages of a single valve module in terms of coaxiality, friction reduction, limiting, assembly, and durability, but also significantly improves the functionality, installation convenience, maintenance efficiency, and water-saving capabilities of the water outlet device through modular, diversion, and multi-path design, facilitating its industrialization and promotion in a wide range of sanitary ware and water supply products.

[0044] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
