Description

Technical Field

[0001] This utility model relates to the field of shower head technology, specifically a thermostatic water-saving shower head. Background Technology

[0002] A shower head is a device installed in a bathroom to spray water for showering. It is typically connected to a hot and cold water mixing pipe, allowing users to adjust the water temperature according to their preferences, and offers various water flow patterns through different nozzle designs, such as rain showers and massage showers. Shower heads are designed to enhance the comfort and convenience of the showering experience.

[0003] Based on the above, the inventors have discovered the following problem: To achieve water-saving effects, many current water-saving showerheads reduce water flow, which may weaken the water flow intensity, affecting the user's showering experience and making it inconvenient to use. Therefore, in view of this, the inventors have researched and improved upon the existing structure and its shortcomings to provide a thermostatic water-saving showerhead, aiming to achieve a more practical purpose. Utility Model Content

[0004] The purpose of this utility model is to provide a thermostatic water-saving shower head to solve the problems mentioned in the background art. A thermostatic water-saving shower head includes a water-saving component, which includes a handle. A thermostatic water interface is provided at the bottom of the handle, and the thermostatic water interface is connected to a connecting component. One end of the connecting component is connected to a thermostatic component. Several water-saving nozzles are fixedly installed on one side of the top of the handle. A venturi cavity is opened at one end of each water-saving nozzle, and a mixing chamber is opened at one end of the venturi cavity. An air inlet is opened on the side of the mixing chamber, and a spray hole is opened at one end of the mixing chamber. A first fan housing is fixedly installed on the outer side of the top of the handle. A handle hole is opened at the bottom of the first fan housing, and a nozzle hole is opened on one side of the first fan housing. The spray hole is located on the outer side of the first fan housing, and the air inlet is located inside the first fan housing. A second fan housing is fixedly installed on one side of the first fan housing, and a waterproof motor is fixedly installed in the middle of the second fan housing. A fan blade is fixedly installed at the output end of the waterproof motor.

[0005] By adopting the above technical solution, the connection component facilitates the connection between the thermostatic component and the water-saving component. The thermostatic component helps balance the ratio of hot and cold water, ensuring a constant water temperature. The water-saving nozzle facilitates the spraying of thermostatic water for showering. The venturi cavity increases the flow rate of water. The mixing chamber accelerates the water flow from the venturi cavity into the mixing chamber. External air enters the mixing chamber through the air inlet and mixes thoroughly with the water flow, forming a mixed fluid with numerous tiny bubbles that is sprayed out from the nozzle, making the sprayed water droplets larger and softer. This reduces the water flow without reducing the impact intensity, improving the showering experience. The first and second air shells facilitate the formation of a sealed air guide cavity at the top of the handle for guiding airflow. The waterproof motor drives the fan blades to generate airflow, creating positive pressure inside the air guide cavity and forcing air from the air inlet into the mixing chamber to mix with the liquid.

[0006] Furthermore, an air inlet is provided on one side of the second air casing, and a mesh is fixedly installed inside the air inlet.

[0007] By adopting the above technical solution, the setting of the air inlet facilitates the rotation of the fan blades, allowing external air to enter the air guide cavity from the air inlet, and the mesh prevents external debris from being drawn into the fan blades.

[0008] Furthermore, the temperature control component includes a control module, which contains a microprocessor and an adjustment chamber.

[0009] By adopting the above technical solution and setting up a microprocessor, it is easy to process various input signals and output control commands according to preset logic and algorithms to adjust the operating state of the device.

[0010] Furthermore, the top of the regulating chamber is connected to a water outlet, and a temperature sensor is fixedly installed on the inner side of the bottom of the water outlet. By adopting the above technical solution, the water outlet facilitates the connection between the thermostatic component and the connecting component, allowing the temperature-regulated water to enter the water-saving component. The temperature sensor monitors the temperature of the water leaving the thermostatic component and provides feedback to the microprocessor for closed-loop control.

[0011] Furthermore, the bottom of the regulating chamber is connected to water inlet ports at both ends, and a proportional valve is provided between the regulating chamber and the water inlet ports. By adopting the above technical solution, the two water inlet ports facilitate connection to external hot water and cold water sources, allowing the microprocessor to control the proportional valve, so that hot and cold water enter the regulating chamber in a certain proportion for mixing, achieving constant temperature output.

[0012] Furthermore, the control module has a display screen and control buttons on its external side, and both the water inlet and outlet are located on the outside of the control module.

[0013] By adopting the above technical solution, the display screen and control buttons make it easy for users to manually set the target water temperature or switch working modes. The display screen shows information such as the current water temperature and the set temperature. The water inlet and outlet are both located on the outside to facilitate connecting the thermostat to the external water source and the connecting component.

[0014] Furthermore, the connecting component includes a connecting pipe, and sealing rings are fixedly installed at both ends of the connecting pipe.

[0015] By adopting the above technical solution and setting the sealing ring, it is easy to increase the sealing degree between the connecting component and the water-saving component and the constant temperature component, and avoid leakage.

[0016] Furthermore, the outer side of the sealing ring is provided with a connection interface, and the two connection interfaces are respectively threaded to the water outlet interface and the constant temperature water interface.

[0017] By adopting the above technical solution and setting the connection interface, it is easy to make a stable and fixed connection between the connecting component and the water-saving component and the constant temperature component.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The connection component facilitates the connection between the thermostatic component and the water-saving component; the thermostatic component facilitates the balance of hot and cold water ratios, ensuring a constant water temperature; the water-saving nozzle facilitates the spraying of thermostatic water for showering; the venturi cavity design facilitates increased water flow velocity; and the mixing chamber design facilitates accelerated water flow from the venturi cavity into the mixing chamber. External air enters the mixing chamber through the air inlet and mixes thoroughly with the water flow, forming a mixed fluid with numerous tiny bubbles that is sprayed out from the nozzle. This invention makes the sprayed water droplets larger and softer, thereby reducing the water flow without reducing the impact intensity of the water flow, thus improving the showering experience. The design of the first and second air chambers facilitates the formation of a sealed air guide cavity at the top of the handle to guide airflow. The waterproof motor allows the fan blades to rotate, generating airflow and creating positive pressure inside the air guide cavity. This forces air from the air inlet into the mixing chamber to mix with the liquid. This invention achieves water reduction without reducing the impact intensity of the water flow, resulting in water conservation while improving the showering experience, and has high practical value.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5This utility model provides a technical solution: a thermostatic water-saving shower head, including a water-saving component 1. The water-saving component 1 includes a handle 11, and a thermostatic water interface 12 is provided at the bottom of the handle 11. The thermostatic water interface 12 is connected to a connecting component 3. The connecting component 3 facilitates the connection between the thermostatic component 2 and the water-saving component 1. One end of the connecting component 3 is connected to the thermostatic component 2. The thermostatic component 2 facilitates the balance of the ratio of hot and cold water, ensuring that the water temperature remains constant. Several water-saving components are fixedly installed on one side of the top of the handle 11. The shower head 13, designed for water conservation, facilitates the spraying of constant-temperature water for showering. One end of the shower head 13 has a Venturi cavity 112, which increases the flow velocity of water. A mixing chamber 113 is located at one end of the Venturi cavity 112, with an air inlet 115 on its side. This allows water to enter the mixing chamber 113 more rapidly from the Venturi cavity 112, while external air enters through the air inlet 115 to fully mix with the water. The mixture forms a fluid containing numerous tiny bubbles, which is then ejected from the nozzle 114, making the water droplets larger and softer. This reduces the water flow rate without reducing the impact intensity, thus improving the showering experience. The nozzle 114 is located at one end of the mixing chamber 113. A first fan housing 14 is fixedly mounted on the outer side of the top of the handle 11. The bottom of the first fan housing 14 has a handle hole 110, and one side of the first fan housing 14 has a nozzle hole 111. The nozzle 114 is located on the outer side of the first fan housing 14, and the air inlet 115 is located inside the first fan housing 14. A second air housing 15 is fixedly installed on one side of the first air housing 14. The arrangement of the first air housing 14 and the second air housing 15 facilitates the formation of a sealed air guide cavity at the top of the grip handle 11 for guiding airflow. A waterproof motor 16 is fixedly installed in the middle of the second air housing 15, and a fan blade 18 is fixedly installed at the output end of the waterproof motor 16. The arrangement of the waterproof motor 16 facilitates the waterproof motor 16 to drive the fan blade 18 to rotate and generate airflow, so that positive pressure is formed inside the air guide cavity, and air is forced from the air inlet 115 into the mixing chamber 113 to mix with the liquid.

[0027] The second air casing 15 has an air inlet 17 on one side, and a mesh 19 is fixedly installed inside the air inlet 17. The air inlet 17 facilitates the rotation of the fan blades 18 so that external air can enter the air guide cavity from the air inlet 17. The mesh 19 prevents external debris from being drawn into the fan blades 18.

[0028] The constant temperature component 2 includes a control module 21, which is equipped with a microprocessor and an adjustment chamber 24. The microprocessor facilitates the processing of various input signals and outputs control commands according to preset logic and algorithms to adjust the operating state of the device.

[0029] The top of the regulating chamber 24 is connected to a water outlet 27, and a temperature sensor 28 is fixedly installed on the inner side of the bottom of the water outlet 27. The water outlet 27 facilitates the connection between the thermostatic component 2 and the connecting component 3, so that the water after temperature regulation can enter the water-saving component 1. The temperature sensor 28 monitors the temperature of the water leaving the thermostatic component 2 and feeds it back to the microprocessor for closed-loop control.

[0030] The regulating chamber 24 has water inlet ports 25 at both ends of its bottom. A proportional valve 26 is provided between the regulating chamber 24 and the water inlet ports 25. The two water inlet ports 25 facilitate the connection to external hot water and cold water sources, and allow the microprocessor to control the proportional valve 26 so that hot water and cold water enter the regulating chamber 24 in a certain proportion for mixing, thereby achieving constant temperature output.

[0031] The control module 21 has a display screen 22 and control buttons 23 on its outer side. The water inlet 25 and water outlet 27 are both located on the outside of the control module 21. The display screen 22 and control buttons 23 make it easy for users to manually set the target water temperature or switch working modes. The display screen 22 displays information such as the current water temperature and the set temperature. The water inlet 25 and water outlet 27 are both located on the outside to facilitate connecting the thermostatic component 2 to the external water source and the connecting component 3.

[0032] The connecting component 3 includes a connecting pipe 31, with sealing rings 32 fixedly installed at both ends. The sealing rings 32 enhance the sealing between the connecting component 3 and the water-saving component 1 and the thermostatic component 2, preventing leakage. The sealing rings 32 are fitted with connecting interfaces 33 on their outer sides. These interfaces 33 are threaded to the water outlet interface 27 and the thermostatic water interface 12, respectively. The connecting interfaces 33 facilitate a secure and fixed connection between the connecting component 3 and the water-saving component 1 and the thermostatic component 2.

[0033] Specifically, the working principle of this thermostatic water-saving shower head is as follows: During use, the display screen 22 and control buttons 23 allow users to manually set the target water temperature or switch working modes. The display screen 22 shows information such as the current water temperature and the set temperature. Both the inlet port 25 and the outlet port 27 are located on the outside to facilitate connecting the thermostatic component 2 to an external water source and the connecting component 3. The two inlet ports 25 facilitate connection to external hot and cold water sources, allowing the microprocessor to control the proportional valve 26, ensuring that hot and cold water enter and regulate in a certain proportion. The mixture is mixed in chamber 24 to achieve constant temperature output. The outlet port 27 facilitates connection between the constant temperature component 2 and the connecting component 3, allowing the temperature-regulated water to enter the water-saving component 1. Temperature sensor 28 monitors the temperature of the water leaving the constant temperature component 2, providing feedback to the microprocessor for closed-loop control. The connection interface 33 ensures a secure connection between the connecting component 3, the water-saving component 1, and the constant temperature component 2. The sealing ring 32 enhances the sealing between the connecting component 3 and the water-saving and constant temperature components 1 and 2. To prevent leakage, the water-saving nozzle 13 facilitates the spraying of constant-temperature water for showering. The venturi cavity 112 increases the flow velocity of the water. The mixing chamber 113 accelerates the water flow from the venturi cavity 112 into the mixing chamber 113. External air enters the mixing chamber 113 through the air inlet 115 and mixes thoroughly with the water flow, forming a mixed fluid with numerous microbubbles that is sprayed out from the nozzle 114. This results in larger and softer water droplets, thus reducing the water flow rate without reducing the impact intensity of the water flow. To improve the showering experience, the first air housing 14 and the second air housing 15 facilitate the formation of a sealed air guide cavity at the top of the handle 11 for guiding airflow. The waterproof motor 16 facilitates the rotation of the fan blades 18 to generate airflow, creating positive pressure inside the air guide cavity. This forces air from the air inlet 115 into the mixing chamber 113 to mix with the liquid. The air inlet 17 facilitates the rotation of the fan blades 18, allowing external air to enter the air guide cavity from the air inlet 17. The mesh 19 prevents external debris from being drawn into the fan blades 18.
