Description

Technical Field

[0001] This utility model belongs to the field of bathroom products, specifically relating to a novel water circuit switching device for showering. Background Technology

[0002] In existing shower systems, water flow switching devices (such as diverters or switching valves) are the core components for achieving different water flow modes (such as overhead shower, hand shower, faucet, etc.). Currently available push-button switching valves change the on / off state of the water flow by pressing different buttons, thus switching the water flow mode. The internal structure of push-button switching valves is usually quite complex. Their valve bodies require multiple independent chambers and intricate water flow channels to accommodate the buttons, springs, seals, and other actuators, ensuring accurate water flow switching between different pathways.

[0003] In the production of such valve bodies, existing technologies generally employ metal die casting (e.g., zinc alloy or aluminum alloy die casting) to first manufacture a blank, followed by secondary precision machining of the internal chambers, flow channels, and sealing surfaces using a CNC machining center. While this combined "die casting + CNC precision machining" process ensures the final functionality of the product, it also brings problems such as high processing costs and limited production efficiency.

[0004] In addition, current shower products often include digital displays or ambient lighting, and a miniature turbine generator is typically installed in the water line to provide power. However, the existing miniature turbine generators are positioned upwards, making subsequent maintenance and replacement very inconvenient. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a novel water circuit switching device for showering, which improves the structural design of the water circuit, reduces processing difficulty, saves raw materials, thereby reducing processing costs and improving production efficiency. In addition, it also improves the setting method of the micro turbine generator, greatly enhancing the convenience of maintenance and replacement of the micro turbine generator.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: A novel water circuit switching device for showering includes a housing, a switch control valve, a lower sealing water valve core device, and a micro turbine generator. A main body is fixedly installed inside the housing. The main body has parallel hot water channels and a mixing channel arranged horizontally. One end of the mixing channel has a downward-facing motor mounting chamber. A first water outlet is located on the upper surface of the main body, a second water outlet on the left surface, and a third and fourth water outlet on the lower surface. A cold water inlet chamber and a hot water inlet chamber are located on the rear side of the main body. A first mounting groove is located on the right end of the front side of the main body, and two second mounting grooves are located on the left end of the front side. The switch control valve is installed in the first mounting groove, and the lower sealing water valve core devices are installed in the second mounting grooves. There are four lower sealing water valve core devices. The first mounting groove has a first water channel, a second water channel, and a third water channel connected to the switch control valve. The second mounting groove has an inlet channel and an outlet channel corresponding to the lower sealing water valve core devices.

[0007] As a further feature of the above scheme, each of the lower sealing water-water ...

[0008] As a further configuration of the above scheme, one end of the first water circuit is connected to the hot water channel, and the other end is connected to the inlet of the switch control valve; one end of the second water circuit is connected to the motor mounting chamber, and the other end is connected to the outlet of the switch control valve; one end of the third water circuit is connected to the cold water inlet chamber, and the other end is connected to the inlet of the switch control valve. Rotating the switch control valve can control the on / off state between the first, second, and third water circuits, thereby controlling the mixing ratio of cold and hot water and achieving the purpose of controlling the water temperature.

[0009] As a further feature of the above scheme, the hot water channel extends to the right, with a first sealing port at the opening of the hot water channel, and the hot water channel is connected to the hot water inlet chamber. The mixing channel extends to the left, with a second sealing port at the opening of the mixing channel, and the mixing channel is connected to the motor mounting chamber.

[0010] As a further feature of the above scheme, the micro turbine generator is installed in the motor mounting chamber, and the lower end of the micro turbine generator is protected by a motor cover, which is fixedly installed on the lower end surface of the outer casing.

[0011] As a further feature of the above scheme, the cold water inlet chamber, hot water inlet chamber, hot water channel, mixing channel, first outlet, second outlet, third outlet, fourth outlet, motor mounting chamber, first water path, second water path, third water path, inlet channel and outlet channel are all straight cylindrical channels, and the connection points between each pair are vertically connected, which facilitates the processing of the channels.

[0012] This utility model has the following beneficial effects: By improving the structural design of the water system, it can be directly processed from profiles without the need for die casting and other processes, further reducing the processing difficulty of the water system and various chambers in the main body and effectively reducing processing costs.

[0013] The internal water system structure is simpler and more compact. When purchasing aluminum profiles, the manufacturer can be asked to directly cut out the excess parts, which greatly saves raw materials and effectively reduces the procurement cost of raw materials.

[0014] The micro turbine generator is positioned downwards, allowing for easy maintenance by simply removing the motor cover. This eliminates the need to remove the entire product from the wall and disassemble the components before disassembling the micro turbine generator, greatly improving the convenience of maintenance and replacement.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-7 This application will be described in detail with reference to the embodiments.

[0019] A novel water circuit switching device for showering includes a housing 1, a switch control valve 3, a bottom-sealed water inlet valve core device 4, and a micro turbine generator 6. A main body 2 is fixedly installed inside the housing 1. The main body 2 has parallel hot water channels 8 and mixing channels 9 arranged horizontally. One end of the mixing channel 9 has a downward-facing motor mounting chamber 207. A first water outlet 203 is located on the upper surface of the main body 2, a second water outlet 204 is located on the left end surface of the main body 2, and a third water outlet 205 and a fourth water outlet 206 are located on the lower end surface of the main body 2. A cold water inlet chamber 201 and a hot water inlet chamber 206 are located on the rear side of the main body 2. The water inlet chamber 202 has a first mounting groove 301 on the right end of the front side of the main body 2 and two second mounting grooves 401 on the left end of the front side of the main body 2. The switch control valve 3 is installed in the first mounting groove 301 and the lower sealing water-water valve core device 4 is installed in the second mounting groove 401. There are 4 lower sealing water-water valve core devices 4. The first mounting groove 301 has a first water passage 3011, a second water passage 3012 and a third water passage 3013 connected to the switch control valve 3. The second mounting groove 401 has a water inlet channel 402 and a water outlet channel 403 corresponding to the lower sealing water-water valve core device 4.

[0020] Each lower sealing water-water ...

[0021] When the bottom sealing water-water valve core device 4 is working, the water flows directly into the valve core and then out. It needs to pass through the chamber before entering the valve core. Therefore, when using the bottom sealing water-water valve core device 4, there is no need to process the corresponding chamber, which can effectively reduce the water circuit structure.

[0022] The first water path 3011 is connected to the hot water channel 8 at one end and to the inlet of the switch control valve 3 at the other end. The second water path 3012 is connected to the motor mounting chamber 207 at one end and to the outlet of the switch control valve 3 at the other end. The third water path 3013 is connected to the cold water inlet chamber 201 at one end and to the inlet of the switch control valve 3 at the other end. Rotating the switch control valve 3 can control the on / off state between the first water path 3011, the second water path 3012 and the third water path 3013, thereby controlling the mixing ratio of cold water and hot water, and achieving the purpose of controlling the water temperature and the on / off state of the switch control valve 3.

[0023] Hot water channel 8 extends to the right and has a first sealing port 801 at its opening. Hot water channel 8 is connected to hot water inlet chamber 202. Mixing channel 9 extends to the left and has a second sealing port 901 at its opening. The first sealing port 801 and the second sealing port 901 are used for sealing. Mixing channel 9 is connected to motor mounting chamber 207.

[0024] The micro turbine generator 6 is installed in the motor mounting chamber 207. The lower end of the micro turbine generator 6 is protected by the motor cover 7, which is fixedly installed on the lower end surface of the outer casing 1. When water flows through the motor mounting chamber 207, it drives the micro turbine generator 6 to generate electricity, thereby powering the digital display or ambient light on the shower product.

[0025] The cold water inlet chamber 201, the hot water inlet chamber 202, the hot water channel 8, the mixing channel 9, the first water outlet 203, the second water outlet 204, the third water outlet 205, the fourth water outlet 206, the motor mounting chamber 207, the first water path 3011, the second water path 3012, the third water path 3013, the water inlet channel 402 and the water outlet channel 403 are all straight cylindrical channels, and the connection points between each pair are vertically connected, which facilitates the processing of the channels.

[0026] The main body 2 is preferably made of aluminum profile, such as aluminum block. A machining center can quickly drill and mill the water channel structure inside the main body 2 horizontally and vertically. Since the water channel of the main body 2 is simpler and more compact, when purchasing aluminum profile, the manufacturer can be asked to remove the hollow part 10, and also remove the first mounting groove 301 and the second mounting groove 401, saving a lot of raw materials. Since the raw materials are priced by weight, the procurement cost can be greatly reduced.

[0027] The working process of this utility model is as follows: When in use, hot water enters the hot water channel through the hot water inlet chamber, and cold water enters the switch control valve 3 through the third water path. Rotating the switch control valve 3 controls the opening and closing of the first water path 3011, the second water path 3012 and the third water path 3013, adjusting the mixing ratio of cold water and hot water. The mixed water flows through the motor mounting chamber 207 and enters the mixing channel 9. Pressing different buttons 5 can control the water to flow from the first outlet 203, the second outlet 204, the third outlet 205 and the fourth outlet 206.

[0028] When water flows through the motor mounting chamber 207, it simultaneously drives the rotation of the micro turbine generator 6. The micro turbine generator 6 generates electricity to power the digital display or ambient light. The electricity generated by the micro turbine generator 6 is low-voltage electricity, which is very safe.

[0029] It should be noted that the switch control valve 3, the lower sealing water sluice valve core device 4, and the micro turbine generator 6 in this device are common components on the market. Those skilled in the art can select appropriate models and specifications according to design requirements. Therefore, the structure and working principle of the switch control valve 3, the lower sealing water sluice valve core device 4, and the micro turbine generator 6 will not be described in detail.

[0030] It should be noted that the directional terms such as "upper," "lower," "front," and "rear" in the above technical solutions are set up to facilitate a clear description of the structure in conjunction with the accompanying drawings, and should not be regarded as a limitation on the technical solutions.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. For those skilled in the art, it is possible to implement this utility model in other specific forms without departing from its spirit or basic characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this utility model.
