Description

Technical Field

[0001] This utility model relates to the field of faucet valve core technology, specifically to a two-hand wheel control valve core. Background Technology

[0002] As a key device for water flow control, the performance of faucets has a crucial impact on user experience and safety. With the continuous improvement of people's living standards and the increasing demand for precise water flow control in industrial production, the design drawbacks of traditional faucets are becoming increasingly apparent.

[0003] Most faucet valve cores on the market currently use a single handwheel or handle drive. In this mode, the water flow rate and water temperature are closely linked and cannot be controlled independently. When a user adjusts the water flow, the water temperature control component is inevitably activated, causing a change in water temperature. For example, in everyday household use, when washing up in the bathroom, if a user wants to reduce the water flow to save water, the difficulty in precisely controlling a single handwheel or handle to adjust only the water flow rate can easily lead to accidental changes in water temperature, causing a sudden increase or decrease in temperature, severely affecting comfort and potentially causing burns or other safety issues. In special locations where water temperature stability is critical, such as hospital wards and research laboratories, unexpected temperature fluctuations can interfere with the normal operation of medical equipment, affect the accuracy of experimental results, and potentially lead to serious consequences.

[0004] While existing technologies also feature dual-drive valve cores used to independently control water temperature and flow rate, their dual-drive mechanism is mostly achieved through a flat-opening rotation. In practical use, this type of flat-opening dual-drive valve core has a relatively simple adjustment method and lacks strong identification, failing to meet diverse operational needs. Furthermore, due to the limitations of the drive structure, a double-acting valve disc must be installed, making the internal structure of the valve core more complex and thus limiting its effectiveness.

[0005] Furthermore, existing faucets generally lack effective anti-collision protection mechanisms in their design. In daily use, especially in public places with high traffic, such as restrooms in schools and shopping malls, faucets are frequently subjected to forceful manipulation due to the large number of users and their varying usage habits. Such forceful manipulation can easily cause the valve stem to bend and other parts to be damaged, further reducing the reliability and stability of the faucet and causing considerable inconvenience to users, thus requiring further improvement.

[0006] In summary, existing faucets have many shortcomings in terms of independent water flow and temperature control, usability, and impact resistance, failing to meet people's demands for high-quality, high-performance faucets. Therefore, developing a faucet with two-hand wheel operation, capable of independently controlling water flow and temperature without mutual interference, while also possessing good operability and impact resistance, is of great practical significance. Summary of the Invention

[0007] The first technical problem to be solved by this utility model is to provide a two-hand wheel control valve core that can independently control the water flow and water temperature, avoid mutual interference, and has good operability, in light of the above-mentioned technical status.

[0008] The second technical problem to be solved by this utility model is to provide a two-hand wheel control valve core with anti-collision performance in view of the above-mentioned technical status.

[0009] The technical solution adopted by this utility model to solve the first technical problem is: the two-hand wheel control valve core includes...

[0010] Valve housing assembly;

[0011] The stationary valve plate is fixed inside the valve body assembly and is provided with a cold water inlet, a hot water inlet, and a mixing outlet.

[0012] A movable valve plate is located above a stationary valve plate and can rotate and slide relative to the stationary valve plate. It has a mixing chamber, which can be connected to or disconnected from the cold water inlet, hot water inlet and mixing outlet through the sliding or rotation of the movable valve plate.

[0013] The valve handle is hinged to the valve housing assembly and can swing back and forth. Its lower end is driven to the moving valve plate. By swinging, the moving valve plate slides relative to the stationary valve plate to adjust the water flow size and opening and closing of the mixing outlet.

[0014] An adjusting sleeve is rotatably mounted on the valve housing assembly and is driven to rotate with the moving valve plate. By rotating the moving valve plate relative to the stationary valve plate, the mixing ratio of the cold water inlet and the hot water inlet entering the mixing chamber is adjusted, thereby controlling the water temperature of the mixing outlet.

[0015] To optimize the overall layout of the valve core structure and facilitate the installation and operation of the valve handle and adjusting sleeve, preferably, the valve housing assembly includes a valve housing and a connecting sleeve disposed on the valve housing. The connecting sleeve has a through-hole mounting cavity formed on it. The valve handle is hinged to the connecting sleeve and passes through the mounting cavity from top to bottom before being driven and connected to the moving valve plate. The adjusting sleeve is rotatably fitted around the outer periphery of the connecting sleeve and is at least partially exposed on the top of the valve housing.

[0016] To ensure that the valve handle and adjusting sleeve can effectively drive the moving valve plate to slide and rotate, and to improve the stability and reliability of the adjustment, preferably, a dial built into the valve housing is also included. The dial is located on the upper end of the moving valve plate and is fixedly connected to the moving valve plate. The valve handle is driven to the dial to drive the dial and the moving valve plate to slide together. The adjusting sleeve is driven to the dial to drive the dial and the moving valve plate to slide and rotate together.

[0017] In order to enable the valve handle to swing more accurately and drive the dial and the moving valve plate to slide, preferably, the valve handle includes an upper end and a lower end that are connected to each other. The lower end is bent relative to the upper end to form an angle. The end of the lower end also forms a spherical connector. The dial has a connecting hole adapted to the connector. The axis of the connecting hole is misaligned with the axis of the dial.

[0018] In order to smoothly drive the dial and the moving valve plate to rotate when the adjusting sleeve rotates, while not affecting the valve handle to drive the dial to slide freely, preferably, the bottom of the adjusting sleeve has a downwardly extending protrusion adjacent to the outer circumference of the adjusting sleeve, and the upper end face of the dial is also provided with a radially extending slot that fits the protrusion, and the radial width of the slot is greater than the radial width of the protrusion to facilitate the protrusion to slide back and forth radially in the slot.

[0019] To facilitate user operation of the adjusting sleeve and enhance the convenience of water temperature adjustment, preferably, the adjusting sleeve has protruding teeth on the outer peripheral surface of the top of the valve housing for connecting an external handwheel.

[0020] To better ensure that the connecting sleeve can be securely installed in the valve body and to provide good support and room for the rotation of the adjusting sleeve, preferably, the bottom of the connecting sleeve has a flange extending laterally outward, the outer circumferential surface of the flange has a fixing groove, the inner circumferential wall of the valve body has a fixing block protruding therein that can be inserted into the fixing groove, the upper end surface of the flange has an annular groove for the lower end of the adjusting sleeve to rotate and adapt, and the flange also has an arc-shaped hole through it for the protrusion to be inserted and for providing circumferential room for movement.

[0021] To facilitate valve core installation, disassembly, and internal component maintenance and replacement, preferably, the valve housing includes an upper shell and a base. The base is detachably connected to the top of the upper shell via a detachable structure. The upper end of the valve handle protrudes from the top of the upper shell. The base is provided with a cold water inlet corresponding to the cold water inlet, a hot water inlet corresponding to the hot water inlet, and a mixing inlet corresponding to the mixing outlet. The detachable structure includes a buckle on the base and a slot on the upper shell that fits the buckle. The upper shell is also provided with a positioning groove, and the base is provided with a positioning block that fits into the positioning groove.

[0022] The technical solution adopted by this utility model to solve the second technical problem is as follows: the side of the valve handle is provided with a limiting block that can be adapted to the top of the connecting sleeve. When the valve handle swings to the set position, the bottom of the limiting block can abut against the top of the connecting sleeve to restrict the valve handle from continuing to swing downward, thereby avoiding damage to the valve core due to misoperation or forceful operation and extending the service life.

[0023] To accurately achieve preset adjustment of water flow and provide users with a more precise adjustment experience, preferably, the top of the connecting sleeve is also formed with a vertically extending gear adjustment wall, and the side of the gear adjustment wall facing the valve stem is formed with multiple horizontally spaced gear adjustment grooves. The valve handle is provided with a gear adjustment rod that can move laterally and fit into the corresponding gear adjustment groove. A reset member is also provided between the gear adjustment rod and the valve handle to drive the gear adjustment rod to always be inserted into the gear adjustment groove without external force.

[0024] Compared with the prior art, the advantages of this utility model are as follows: The water flow and opening / closing are adjusted by controlling the sliding of the moving valve plate through the swinging valve handle, and the water temperature is adjusted by controlling the rotation of the moving valve plate through the rotation of the adjusting sleeve. This achieves independent control of water flow and water temperature, avoiding the drawbacks caused by mutual interference in the prior art. In household use, adjusting the water flow will no longer affect the water temperature, improving comfort and safety. In places with strict water temperature requirements, it ensures that the water temperature remains stable within the preset temperature range. Furthermore, the different movement modes of the valve handle and adjusting sleeve allow users to clearly distinguish between the adjustment methods for water flow and water temperature, thus giving the valve core excellent operability. Additionally, the limiting block on the side of the valve handle allows the valve handle to abut against the top of the connecting sleeve when it swings to the set position, limiting excessive swinging of the valve handle and preventing bending of the valve stem or damage to components due to excessive force, thus improving the reliability and stability of the faucet.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Figures 1-11 The diagram shown is a schematic of this embodiment. The two-hand wheel control valve core in this embodiment mainly consists of a valve housing assembly 1, a stationary valve plate 2, a moving valve plate 3, a valve handle 4, an adjusting sleeve 5, and a dial 6. The specific structure of each component, their connection method, and how they work together to adjust the water flow and water temperature will be described in detail below.

[0038] The structure and connection method of each component are described below:

[0039] Valve housing assembly 1: Reference Figures 1 to 6As shown, the valve housing assembly 1 includes a valve housing 11 and a connecting sleeve 12 disposed on the valve housing 11. The valve housing 11 further includes an upper housing 111 and a base 112. The base 112 is detachably connected to the bottom of the upper housing 111 via a detachable structure. The detachable structure includes a snap fastener 112d disposed on the base 112 and a slot 111a disposed on the upper housing 111 that can be fitted with the snap fastener 112d. The upper housing 111 is also provided with a positioning slot 111b, and the base 112 is provided with a positioning block 112e that can be fitted into the positioning slot 111b. This design facilitates the assembly and disassembly of the valve core and makes it convenient for the maintenance and replacement of internal components. The base 112 is provided with a cold water inlet 112a that is connected to the cold water inlet 2a, a hot water inlet 112b that is connected to the hot water inlet 2b, and a mixing inlet 112c that is connected to the mixing outlet 2c.

[0040] Connecting sleeve 12: Reference Figures 3 to 6 As shown, the connecting sleeve 12 has a through-hole 12a. A flange 12b extending laterally outwards is formed at the bottom of the connecting sleeve 12. A fixing groove 12c is formed on the outer circumferential surface of the flange 12b. A fixing block 11a protrudes from the inner circumferential wall of the valve body 11 and can be inserted into the fixing groove 12c. Through this insertion method, the connecting sleeve 12 is securely installed inside the valve body 11. An annular groove 12c is formed on the upper end face of the flange 12b to accommodate the rotation of the lower end of the adjusting sleeve 5, providing support and guidance for the rotation of the adjusting sleeve 5. An arc-shaped hole 12d extending vertically through the flange 12b is also provided for the insertion of the protrusion 5a and to provide circumferential movement space.

[0041] In addition, a vertically extending gear adjustment wall 12e is formed on the top of the connecting sleeve 12. Multiple horizontally spaced gear adjustment grooves 12f are formed on the side of the gear adjustment wall 12e facing the valve handle 4. The valve handle 4 is also provided with a gear adjustment rod 12g that moves laterally and can fit into the corresponding gear adjustment groove 12f. A reset member 12f is provided between the gear adjustment rod 12g and the valve handle 4 to ensure that the gear adjustment rod 5d is always inserted into the gear adjustment groove 12f without external force. This structure enables gear adjustment of the water flow, allowing the user to clearly feel the gear position when the valve handle 4 swings, thus improving the user experience.

[0042] Static valve plate 2: Reference Figures 3 to 6 As shown, the stationary valve plate 2 is fixed inside the valve housing 11 assembly 1, and has a cold water inlet 2a, a hot water inlet 2b, and a mixing outlet 2c. These holes are respectively connected to the cold water inlet 112a, the hot water inlet 112b, and the mixing outlet 112c on the base 112, providing channels for the entry of cold water and hot water and the outflow of mixed water.

[0043] Dynamic valve plate 3: Reference Figures 3 to 6As shown, the movable valve plate 3 is located above the stationary valve plate 2 and can rotate and slide relative to the stationary valve plate 2. The movable valve plate 3 is provided with a mixing chamber 3a. The mixing chamber 3a can be connected or disconnected with the cold water inlet hole 2a, the hot water inlet hole 2b and the mixing outlet hole 2c by the sliding or rotation of the movable valve plate 3, thereby realizing the control of water flow and the adjustment of water temperature.

[0044] Valve handle 4: Reference Figures 1 to 6 As shown, the valve handle 4 is hinged to the connecting sleeve 12 of the valve housing 11 assembly 1 and can swing back and forth. Its lower end is drivenly connected to the moving valve plate 3. The valve handle 4 includes an upper end 4a and a lower end 4b connected to each other. The lower end 4b is bent relative to the upper end 4a to form an included angle α, the optimal angle of which is 170°. The end of the lower end 4b also forms a spherical connector 4b1. The dial 6 has a connecting hole 6a adapted to the connector 4b1. The axis of the connecting hole 6a is misaligned with the axis of the dial 6 and has a gap. When the valve handle 4 swings, the dial 6 and the moving valve plate 3 slide relative to the stationary valve plate 2 through the cooperation of the connector 4b1 and the connecting hole 6a, so as to adjust the water flow size and opening and closing of the mixing outlet hole 2c. The valve handle 4 has a protruding limit block 4c on its side that can fit onto the top of the connecting sleeve 12. When the valve handle 4 swings to the set position, the bottom of the limit block 4c can abut against the top of the connecting sleeve 12 to limit the valve handle 4 from swinging downward, thus playing a role in anti-collision protection.

[0045] Adjustment sleeve 5: Reference Figures 1 to 6 As shown, the adjusting sleeve 5 is rotatably mounted on the connecting sleeve 12 of the valve housing 11 assembly 1 and is drivenly connected to the moving valve plate 3. The adjusting sleeve 5 is rotatably fitted around the outer periphery of the connecting sleeve 12 and is at least partially exposed on the top of the valve housing 11. A tooth 5b is formed on the exposed outer peripheral surface of the valve housing 11 for connecting an external handwheel, facilitating user rotation of the adjusting sleeve 5. A protrusion 5a extending downwards and adjacent to the outer peripheral surface of the adjusting sleeve 5 is formed at the bottom of the adjusting sleeve 5. A slot 6b extending radially and fitting the protrusion 5a is also provided on the upper end face of the dial 6. The radial width of the slot 6b is greater than the radial width of the protrusion 5a to facilitate the protrusion 5a sliding back and forth radially within the slot 6b. When the adjusting sleeve 5 is rotated, the protrusion 5a simultaneously drives the dial 6 and the moving valve plate 3 to rotate relative to the stationary valve plate 2, thereby adjusting the mixing ratio of the cold water inlet hole 2a and the hot water inlet hole 2b entering the mixing chamber 3a, and thus controlling the water temperature at the mixing outlet hole 2c. Since the protrusion 5a here can also slide back and forth radially within the slot 6b, it can also better cooperate with the valve plate 3 when it slides.

[0046] Dial 6: Reference Figures 3 to 6As shown, the dial 6 is built into the valve housing 11, located on the upper end of the moving valve plate 3, and fixedly connected to the moving valve plate 3. It serves to transmit power. On the one hand, it drives the moving valve plate 3 to slide by swinging the valve handle 4; on the other hand, it drives the moving valve plate 3 to rotate by rotating the adjusting sleeve 5.

[0047] The working principle of the dual-wheel control valve core in this embodiment is as follows:

[0048] Water flow adjustment: The user swings the valve handle 4, causing the ball-shaped connector 4b1 at the lower end of the valve handle 4 to move within the connection hole 6a of the dial 6, thus driving the dial 6 and the moving valve plate 3 to slide relative to the stationary valve plate 2. The sliding of the moving valve plate 3 changes the communication area between the mixing chamber 3a and the mixing outlet 2c, thereby adjusting the water flow. When the moving valve plate 3 completely cuts off the connection between the mixing chamber 3a and the mixing outlet 2c, the water flow is shut off. Figure 7 The image shows that the mixing outlet 2c is in the closed state. Figure 8 As shown, the movable valve plate 3 slides to the opening state of the mixing outlet hole 2c under the action of the valve handle 4, at which time the ratio of hot and cold water is consistent. During the process of adjusting the water flow by swinging the valve handle 4, the gear adjustment rod 5d will be engaged into different gear adjustment slots 12f in sequence under the action of the reset part 5e, providing the user with clear gear feedback.

[0049] Water temperature adjustment: The user rotates the adjusting sleeve 5 by turning the external handwheel connected to the insert 5b. The protrusion 5a at the bottom of the adjusting sleeve 5 slides in the slot 6b of the dial 6 and drives the dial 6 to rotate, which in turn drives the moving valve plate 3 to rotate relative to the stationary valve plate 2. The rotation of the moving valve plate 3 changes the connection ratio between the mixing chamber 3a and the cold water inlet 2a and the hot water inlet 2b, thereby adjusting the mixing ratio of cold water and hot water entering the mixing chamber 3a and achieving water temperature adjustment. Figure 9 The diagram shows the moving valve plate 3 rotating under the influence of the adjusting sleeve 5 until the cold water ratio is greater than the hot water ratio. Figure 10 The movable valve plate 3 rotates under the drive of the adjusting sleeve 5 until the hot water ratio is greater than the cold water ratio. Figure 11 The valve plate 3 slides back to the closed state when the valve handle 4 swings.
