Description

Technical Field

[0001] This invention relates to the field of intelligent heating, ventilation and air conditioning technology, specifically to an intelligent bathroom valve system. Background Technology

[0002] With the increasing intelligence of bathroom appliances, thermostatic mixing valves have gradually become an important component of modern bathroom systems. By adjusting the ratio of hot and cold water, they maintain the output water temperature within a relatively stable range, improving user comfort and preventing the risk of scalding due to temperature fluctuations. Therefore, thermostatic control structures are widely used in various shower faucets, thermostatic valves, and intelligent bathroom control systems.

[0003] In existing technologies, most common thermostatic valve structures rely on the principle of metal thermal expansion and deformation for temperature regulation. For example, by incorporating temperature-sensitive elements such as bimetallic strips, shape memory alloy components, or metal expansion rods, when the mixing water temperature changes, the temperature-sensitive metal element expands when heated or contracts when cooled, thereby pushing the valve core or regulating rod to move, thus changing the opening of the hot and cold water channels and achieving automatic adjustment of the mixing water temperature. This type of structure is characterized by its simplicity and high reliability in practical applications, and is therefore widely used in traditional thermostatic mixing valve products.

[0004] However, the aforementioned thermostatic structures relying on the thermal expansion and deformation of metals still have certain shortcomings. First, metal materials have a relatively small coefficient of thermal expansion, resulting in limited deformation during water temperature changes. Therefore, a longer heat conduction and deformation process is required to generate sufficient displacement, leading to a slow thermostatic control response. When the inlet water temperature or pressure changes significantly, the valve often cannot complete the adjustment in a short time, easily causing large fluctuations in the outlet water temperature. Second, some traditional thermostatic valve structures mainly rely on automatic thermostatic mechanisms for adjustment, lacking flexible manual adjustment mechanisms. When users need to adjust the temperature or flow rate according to actual usage requirements, the adjustment method is relatively simple, resulting in low ease of use. Furthermore, some existing valve structures typically use a single valve core structure for hot and cold water flow control, failing to achieve effective coordination between manual and automatic thermostatic control, thus making it difficult to balance adjustment flexibility and temperature stability during use.

[0005] Therefore, in view of the problems of slow response speed, low adjustment sensitivity, and difficulty in effectively combining manual and automatic adjustment functions in the traditional thermostatic valve structure that relies on the thermal expansion and deformation of metal for temperature regulation, it is necessary to provide a new intelligent bathroom valve system. By improving the thermostatic control structure and flow regulation structure, the valve can improve the response speed while maintaining the thermostatic regulation function, and realize the combination of manual and automatic adjustment, thereby improving the overall performance and user experience of the bathroom valve system. Summary of the Invention

[0006] This invention aims to solve the problems of slow response speed, insufficient adjustment sensitivity, and difficulty in effectively combining automatic adjustment structure and manual control structure in existing bathroom thermostatic valves that typically rely on the thermal expansion deformation of metal for temperature regulation. It provides an intelligent bathroom valve system that achieves rapid response and adjustment when water temperature changes through the cooperation of a liquid thermal expansion drive structure and a threaded adjustment structure. Simultaneously, by combining a manual flow control structure, the valve system can have both manual control and mechanical automatic adjustment functions, thereby improving the stability and safety of thermostatic control.

[0007] To achieve the above objectives, this invention provides an intelligent bathroom valve system, including a main valve body, a thermostatic control component, a transducer component, and a temperature display embedded in the surface of the main valve body. The main valve body surface is provided with a hot water inlet, a cold water inlet, and a mixing outlet, as well as a hot valve button and a cold valve button rotatably mounted at both ends of the main valve body. The hot water inlet has a valve grille hole inside. A main control cylinder, connected to the end of the hot valve button, is rotatably mounted inside the main valve body. Rotation of the hot valve button drives the main control cylinder to deflect. The main control cylinder surface has several strip valve holes of different widths, and the outer circumference of the main control cylinder slides against the inner side of the valve grille holes. A cold water valve core located inside the main valve body is rotatably connected to the shaft end of the cold valve button. The hot valve button drives the main control cylinder to rotate, causing the strip valve holes of different widths to align with the valve grille holes to varying degrees, thereby changing the connection opening between the hot water inlet and the mixing outlet, achieving manual adjustment of the hot water flow rate. The cold valve button drives the cold water valve core to move axially, achieving adjustment of the opening between the cold water inlet and the mixing outlet, thereby achieving basic adjustment of the hot and cold water ratio.

[0008] In a preferred embodiment, the main control cylinder and the outer periphery of the cold water valve core are further configured to slide against the inner wall of the main valve body, and both the main control cylinder and the cold water valve core are fitted with sealing rings. By setting the sealing ring structure, the sealing performance inside the valve can be improved, preventing water leakage inside the valve body. Specifically, this ensures the stability and reliability of the hot and cold water flow regulation process.

[0009] In a preferred embodiment, the cold water valve core is further configured such that it is located between the cold water inlet and the mixing outlet. Axial movement of the cold water valve core controls the opening degree between the cold water inlet and the mixing outlet. The various valve holes on the surface of the main control cylinder are evenly arranged circumferentially along the main control cylinder, and the width of each valve hole gradually increases circumferentially. Different valve holes, when engaged with valve grilles, control the opening degree between the hot water inlet and the mixing outlet. Specifically, by cooperating with valve holes of different widths and valve grilles, graded adjustment of the hot water flow rate can be achieved, allowing users to perform precise control according to their needs.

[0010] In a preferred embodiment, the thermostatic control assembly includes a heat pipe and a rotary valve strip. The heat pipe is fixed inside the main control cylinder, and the rotary valve strip is rotatably mounted inside the heat pipe. Both the heat pipe and the rotary valve strip are metal spiral structures with mutually compatible pitch specifications. Through the deflection movement of the rotary valve strip inside the heat pipe, axial movement can be generated under the action of the thread lead, thereby changing the degree of obstruction of the inner port of the valve orifice by the combined structure of the rotary valve strip and the heat pipe. Specifically, this enables automatic adjustment of the flow rate of hot water entering the main control cylinder.

[0011] In a preferred embodiment, the transducer assembly is further configured as follows: the transducer includes a piston tube, a rotating ring, and a sliding lug fixed to one end of the rotary valve strip. The piston tube is connected to the heat pipe and is filled with a thermoplastic fluid. Under the pressure of thermal expansion and contraction of the thermoplastic fluid, the rotating ring is driven to deflect. The rotating ring has a guide protrusion on its surface, and the sliding lug is slidably fitted onto the guide protrusion surface. The piston tube, in conjunction with the rotary valve strip, causes the rotary valve strip to deflect. Specifically, when the water temperature rises, the thermoplastic fluid generates expansion pressure, which, through the rotating ring and sliding lug structure, drives the rotary valve strip to rotate. This causes the rotary valve strip to be axially pushed towards the inner side of the main control cylinder under the action of the heat pipe thread, thereby reducing the opening of the valve orifice and achieving automatic suppression and regulation of the hot water inflow.

[0012] In a preferred embodiment, the rotating ring is rotatably mounted inside the piston tube and coaxially arranged with the heat pipe and the rotary valve strip. The piston tube includes an arc-shaped piston tube and an arc-shaped piston movably sleeved inside the piston tube. The arc-shaped piston structure generates displacement under the pressure of thermal expansion and fluid change, causing the rotating ring to deflect. Specifically, the pressure generated by the thermal expansion of the liquid can be effectively converted into a rotational driving force, thereby improving the sensitivity of temperature regulation.

[0013] In a preferred embodiment, the main valve body is further configured such that a temperature probe electrically connected to a temperature display is located on its inner side, and a hydraulic turbine is located on the inner side of the mixing outlet. The hydraulic turbine provides power input to the temperature display under the drive of water flow. Specifically, the water flow power generation structure of the hydraulic turbine can provide power to the temperature display without an external power source, allowing users to monitor the mixing water temperature in real time and improving bathroom safety.

[0014] The beneficial effects achieved by this invention are as follows: 1. In this invention, by setting a threaded fit structure between the heat pipe and the rotary valve bar, when the rotary valve bar deflects, it can move axially under the threaded guidance of the heat pipe, so that the rotary valve bar gradually enters into the inner side of the main control cylinder and forms a combined shielding structure with the heat pipe, forming a variable seal on the inner port of the valve orifice, thereby realizing the automatic adjustment of the valve orifice opening, so that the amount of hot water entering automatically decreases or increases with the temperature change, achieving a stable and reliable constant temperature regulation effect.

[0015] 2. In this invention, the main control cylinder is rotated by the hot valve knob, causing the valve holes of different widths on the surface of the main control cylinder to align with the valve grid holes to different degrees. This changes the connection opening between the hot water inlet and the mixing outlet, enabling manual adjustment of the hot water flow rate. This, combined with the automatic adjustment of the valve hole opening by the rotary valve bar, allows the device to simultaneously possess manual control and automatic mechanical adjustment functions, improving the adjustment flexibility and safety of the valve system.

[0016] 3. In this invention, by setting a thermally expanding fluid inside the piston tube, the transducer component uses the pressure generated by the thermal expansion and contraction of the liquid to drive the rotating ring to deflect, and the guide protrusion and sliding lug drive the rotary valve strip for adjustment. Compared with the traditional constant temperature structure that relies on the thermal expansion deformation of metal for adjustment, the liquid thermal expansion response speed is faster and the adjustment sensitivity is higher, so it can compensate for water temperature changes more timely and improve the stability and response performance of constant temperature control.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0020] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0021] The following describes, with reference to the accompanying drawings, some embodiments of an intelligent bathroom valve system provided by the present invention.

[0022] Combination Figures 1-6 As shown, the present invention provides an intelligent bathroom valve system, including a main valve body 100, a thermostatic control component 200, a transducer component 300, and a temperature display 400 embedded in the surface of the main valve body 100. The main valve body 100 serves as the main structure of the entire valve system, forming a hot and cold water mixing channel internally and housing various functional components. The surface of the main valve body 100 is provided with a hot water inlet 101, a cold water inlet 102, and a mixing outlet 103, for connecting to hot water pipes, cold water pipes, and outputting mixed water flow, respectively. A hot valve button 110 and a cold valve button 120 are rotatably mounted at both ends of the main valve body 100, for basic adjustment of the hot and cold water flow rates.

[0023] In this embodiment, a valve grille hole 104 is provided inside the hot water inlet 101, and a main control cylinder 130 connected to the end of the thermostatic valve button 110 is rotatably mounted inside the main valve body 100. Rotating the thermostatic valve button 110 can cause the main control cylinder 130 to deflect within the main valve body 100. The outer periphery of the main control cylinder 130 forms a sliding fit with the inner side of the valve grille hole 104, and several strip valve holes 131 of different widths are circumferentially opened on the surface of the main control cylinder 130. When the main control cylinder 130 deflects, the strip valve holes 131 of different widths engage with the valve grille hole 104 to different degrees, thereby changing the connection opening between the hot water inlet 101 and the mixing outlet 103, and realizing the regulation of hot water flow.

[0024] In this embodiment, the cold water valve core 140 located inside the main valve body 100 is rotatably connected to the shaft end of the cold water valve button 120. The cold water valve core 140 is disposed between the cold water inlet 102 and the mixing outlet 103, and can move axially under the drive of the cold water valve button 120, thereby changing the channel opening between the cold water inlet 102 and the mixing outlet 103 to achieve cold water flow regulation. The outer periphery of both the main control cylinder 130 and the cold water valve core 140 forms a close sliding fit with the inner wall of the main valve body 100, and sealing rings are embedded and installed on the outer periphery of both the main control cylinder 130 and the cold water valve core 140 to ensure the fluid sealing performance inside the valve body.

[0025] In this embodiment, the valve holes 131 on the surface of the main control cylinder 130 are evenly arranged circumferentially along the main control cylinder 130, and the width of each valve hole 131 gradually increases circumferentially. When the main control cylinder 130 rotates, the opening between the hot water inlet 101 and the mixing outlet 103 is continuously adjusted by changing the contact area between the valve holes 131 of different widths and the valve grille hole 104, thereby enabling precise control of the hot water flow rate as needed.

[0026] In this embodiment, the constant temperature control component 200 includes a heat pipe 210 and a rotary valve strip 220. The heat pipe 210 is fixedly installed inside the main control cylinder 130, and the rotary valve strip 220 is rotatably installed inside the heat pipe 210. Both the heat pipe 210 and the rotary valve strip 220 adopt a metal spiral structure, and their pitch specifications are compatible. The heat pipe 210 is a hollow tubular structure, and its interior communicates with the inner cavity of the piston tube 310 of the transducer component 300.

[0027] In this embodiment, the transducer assembly 300 includes a piston tube 310, a rotating ring 320, and a lug 330 fixed to one end of a rotary valve strip 220. The piston tube 310 is connected to the heat pipe 210 and is filled with a thermoplastic fluid. The rotating ring 320 is rotatably mounted inside the piston tube 310 and is coaxially arranged with the heat pipe 210 and the rotary valve strip 220. The piston tube 310 includes an arc-shaped piston tube and an arc-shaped piston movably fitted inside the arc-shaped piston tube. Under the pressure of the thermoplastic fluid, the arc-shaped piston can generate displacement inside the piston tube 310, driving the rotating ring 320 to deflect.

[0028] In this embodiment, the rotating ring 320 has a guide protrusion 321 on its surface, and the sliding lug 330 is slidably sleeved on the surface of the guide protrusion 321. Through the sliding engagement structure of the guide protrusion 321 and the sliding lug 330, the rotating ring 320 can be driven to rotate when it deflects. Since the rotating valve strip 220 and the heat pipe 210 are threadedly engaged, the rotating valve strip 220 will move axially relative to the heat pipe 210 under the action of the thread lead during rotation, causing the rotating valve strip 220 to gradually enter axially towards the inside of the main control cylinder 130.

[0029] As the rotary valve strip 220 is pushed into the main control cylinder 130 under the threaded guidance of the heat pipe 210, the combined structure of the rotary valve strip 220 and the heat pipe 210 gradually forms a shielding and sealing effect on the inner port of the valve hole 131 on the surface of the main control cylinder 130, thereby changing the effective opening of the valve hole 131 and causing a change in the flow rate of hot water into the main control cylinder 130. The greater the degree of thermal expansion of the fluid, the greater the deflection of the rotating ring 320, the greater the axial feed of the rotary valve strip 220 under the threaded action of the heat pipe 210, and the higher the degree of sealing formed on the inner port of the valve hole 131, thereby reducing the flow rate of hot water into the main control cylinder 130 and realizing the automatic adjustment of the mixing water temperature.

[0030] In this embodiment, a temperature probe electrically connected to the temperature display 400 is provided inside the main valve body 100 for real-time detection of the water temperature at the mixing outlet 103. A hydraulic turbine 410 is provided inside the mixing outlet 103. The hydraulic turbine 410 rotates under hydraulic pressure when water flows through it, generating electrical energy to provide power input to the temperature display 400. Through the self-generating structure of the hydraulic turbine 410, the temperature display 400 can achieve water temperature display without an external power source.

[0031] With the above-described structure, the present invention achieves basic regulation of hot and cold water flow through the hot valve button 110 and the cold valve button 120, and achieves automatic compensation and regulation when the water temperature changes through the constant temperature control component 200 and the transducer component 300. At the same time, the water turbine 410 provides power to the temperature display 400, enabling users to observe the mixed water temperature in real time, thereby realizing an intelligent bathroom valve system with automatic temperature regulation and temperature display functions.

[0032] Working principle and usage process of this invention: During use, hot water enters the main valve body 100 through the hot water inlet 101, and cold water enters the main valve body 100 through the cold water inlet 102. The two waters mix inside the main valve body 100 and are then discharged through the mixing outlet 103. Users can adjust the basic flow rates of hot and cold water by rotating the hot valve knob 110 and the cold valve knob 120. The hot valve knob 110 is connected to the main control cylinder 130. The thermostatic control component 200 and the transducer component 300 rotate synchronously. When the hot valve knob 110 rotates, it causes the main control cylinder 130 to deflect inside the main valve body 100, causing the valve holes 131 of different widths on the surface of the main control cylinder 130 to align with the valve grille holes 104 to varying degrees. This changes the connection between the hot water inlet 101 and the mixing outlet 103, thus regulating the hot water flow rate. Simultaneously, rotating the cold water valve knob 120 causes the cold water valve core 140 to move axially within the main valve body 100, changing the opening of the channel between the cold water inlet 102 and the mixing outlet 103, thereby regulating the cold water flow rate. This method enables initial adjustment of the hot and cold water ratio.

[0033] When the water temperature changes, the thermostatic control component 200 and the transducer component 300 work together to regulate the temperature. The heat pipe 210 in the thermostatic control component 200 is fixed inside the main control cylinder 130, and the rotary valve strip 220 is rotatably installed inside the heat pipe 210. The heat pipe 210 and the rotary valve strip 220 have a mutually compatible threaded structure. When the mixed water temperature rises, the thermally expanding fluid filled in the piston tube 310 of the transducer component 300 generates expansion pressure under the influence of temperature, thereby driving the rotating ring 320 to deflect. The guide protrusion 321 on the surface of the rotating ring 320 and the sliding lug 330 form a sliding fit relationship, causing the rotary valve strip 220 to rotate during the deflection of the rotating ring 320.

[0034] Because the rotary valve strip 220 and the heat pipe 210 have a threaded fit, when the rotary valve strip 220 rotates, it will move axially relative to the heat pipe 210 under the action of the thread lead, causing the rotary valve strip 220 to gradually enter the inner side of the main control cylinder 130 axially. The combined structure of the heat pipe 210 and the rotary valve strip 220 is located inside the valve hole 131. When the rotary valve strip 220 is pushed into the inner side of the main control cylinder 130, the structure between it and the heat pipe 210 gradually forms a shielding and sealing effect on the inner port of the valve hole 131, thereby reducing the effective opening of the valve hole 131 and gradually reducing the flow rate of hot water entering the main control cylinder 130.

[0035] As the water temperature continues to rise, the expansion of the thermally expanded fluid increases further, leading to a greater deflection amplitude of the rotating ring 320 and a corresponding increase in the rotation angle of the rotary valve strip 220. This, combined with the threaded guidance of the heat pipe 210, generates a larger axial feed, further blocking the inner port of the valve orifice 131 and reducing the flow rate of hot water into the main control cylinder 130. This method automatically suppresses and regulates the hot water flow, preventing the mixed water temperature from rising further and achieving automatic thermostatic control.

[0036] When the water temperature decreases, the thermal expansion and fluid contraction inside the piston tube 310 reduces the deflection angle of the rotating ring 320. Under the threaded guidance of the heat pipe 210, the rotary valve strip 220 gradually retracts, reducing the degree of obstruction of the inner port of the valve hole 131 and increasing the effective opening of the valve hole 131. This increases the flow rate of hot water into the main control cylinder 130, allowing the mixing temperature to return to the set range.

[0037] Meanwhile, a hydraulic turbine 410 is installed inside the mixing outlet 103. When water flows through the mixing outlet 103, the hydraulic turbine 410 rotates under the drive of the water flow and generates electrical energy, providing power input to the temperature display 400 installed on the surface of the main valve body 100. A temperature probe installed inside the main valve body 100 is electrically connected to the temperature display 400 to detect and display the water temperature at the mixing outlet 103 in real time, allowing the user to intuitively understand the current outlet water temperature.

[0038] With the above-mentioned structural combination, the present invention can not only realize the basic adjustment of the hot and cold water ratio through the hot valve button 110 and the cold valve button 120, but also rely on the constant temperature control component 200 and the energy transducer component 300 to automatically compensate and adjust the water temperature changes. At the same time, the water turbine 410 provides self-generated power to the temperature display 400 to realize real-time water temperature display, thereby improving the safety, stability and intelligence of the bathroom valve system.
