Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of thermostatic shower equipment, specifically a split-type three-function thermostatic shower. Background Technology
[0002] Mechanical thermostatic valves regulate temperature through the physical properties of thermosensitive elements (such as paraffin wax, bimetallic strips, or shape memory alloys). Taking shape memory alloys as an example, their internal spiral temperature sensor expands and contracts with temperature changes, directly controlling the flow rate of hot and cold water. The thermostatic valve, through a highly sensitive shape memory alloy sensor, contracts to reduce the hot water flow when the temperature rises and expands to increase the hot water flow when the temperature falls, thereby stabilizing the outlet water temperature within the range of 25-55℃. However, current thermostatic showers have the following problems: the control unit and the thermostatic unit cannot be installed separately, which is not conducive to fine temperature control. Utility Model Content
[0003] The purpose of this invention is to provide a split-type three-function thermostatic shower to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a split-type three-function thermostatic shower, including an outer shell, a gear handwheel rotatably provided on one side of the outer shell, a thermostatic handwheel rotatably provided on the other side of the outer shell, a check valve connected to the rear end of the outer shell via a hot water pipe, a cold water pipe connected to the other side of the rear end of the outer shell, a first interface connected to the upper part of the outer shell, and a second interface connected to the lower end of the outer shell. The thermostatic handwheel is used for temperature control. The first interface controls the thermostatic valve core adjustment by rotating it, thereby changing the hot and cold water ratio. The gear shift handwheel is used for flow regulation. The gear shift handwheel controls the flow rate of the mixed water through the gear shift valve core, so that the mixed water is discharged through the first interface and the second interface.
[0005] Specifically, the hot water pipe passes through the outer casing and is connected to the guide pipe to introduce hot water.
[0006] Specifically, the side end of the guide tube is connected to the thermostatic valve core, and the thermostatic valve core is connected to the cold water pipe.
[0007] Specifically, the thermostatic valve core is provided with a mixing space for mixing hot and cold water, and the mixed water is transmitted through the lower end of the guide pipe and guided to the gear valve core.
[0008] Specifically, the gear valve core changes the size of the channel at the docking position with the guide tube by rotating.
[0009] Specifically, the thermostatic valve core changes the size of the channel between the thermostatic valve core and the guide tube by rotating, and at the same time changes the size of the channel at the connection position between the thermostatic valve core and the cold water pipe.
[0010] Compared with the prior art, the beneficial effects of this utility model are: The housing provides support, while the check valve and hot water pipe introduce hot water, guiding it to the guide pipe and then to the thermostatic valve core. The cold water pipe connects to the thermostatic valve core, introducing cold water. The ratio of hot and cold water can be adjusted by the thermostatic handwheel, allowing the mixed water to flow within the thermostatic valve core. The mixed water is then guided through the lower end of the guide pipe to the position valve core. The position valve core, adjusted by the position handwheel, changes the water flow rate, allowing the water to be discharged through the first and second interfaces. This structure separates the position valve body and the thermostatic body, facilitating precise temperature control and flow rate regulation. The modular design also allows for easy disassembly and maintenance, enabling the system to function as a three-in-one unit. Attached Figure Description

[0013] 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.
[0014] Please see Figure 1-2 This utility model provides a technical solution: a split-type three-function thermostatic shower, including a shell 2, a gear handwheel 5 is rotatably provided on one side of the shell 2, a thermostatic handwheel 7 is rotatably provided on the other side of the shell 2, a check valve 3 is connected to the rear end of the shell 2 through a hot water pipe 4, a cold water pipe 8 is connected to the other side of the rear end of the shell 2, a first interface 1 is connected to the upper part of the shell 2, and a second interface 6 is connected to the lower end of the shell 2. The thermostatic handwheel 7 is used for temperature control. The first interface 1 controls the thermostatic valve core 11 to adjust and change the hot and cold water ratio by rotating it. The handwheel 5 is used for flow regulation. The handwheel 5 controls the flow rate of the mixed water via the valve core 10, allowing the mixed water to be discharged through the first interface 1 and the second interface 6. The housing 2, which provides support, guides hot water through the check valve 3 and hot water pipe 4, leading to the guide pipe 9, which then guides the water into the thermostatic valve core 11. The cold water pipe 8 connects to the thermostatic valve core 11, introducing cold water. Under the control of the thermostatic handwheel 7, the ratio of hot and cold water can be adjusted, ensuring the mixed water flows smoothly within the thermostatic valve core 11. The mixture is internally mixed and then guided and transmitted through the lower end of the guide pipe 9 to the gear valve core 10. At this time, the gear valve core 10 can be adjusted by rotating the gear handwheel 5 to change the water output, so that the water flow is guided and discharged through the first interface 1 and the second interface 6. This structure separates the gear body and the thermostat body, which is conducive to fine temperature control and flow control. At the same time, this structure is easy to disassemble and install, and convenient for subsequent maintenance, thus achieving the purpose of three-function use.
[0015] Hot water pipe 4 passes through outer casing 2 and is connected to guide pipe 9 to introduce hot water.
[0016] The side end of the guide pipe 9 is connected to the thermostatic valve core 11, and the thermostatic valve core 11 is connected to the cold water pipe 8.
[0017] The thermostatic valve core 11 has a mixing space for mixing hot and cold water, and the mixed water is transmitted through the lower end of the guide pipe 9 and guided to the gear valve core 10.
[0018] The gear valve core 10 changes the size of the channel at the docking position with the guide tube 9 by rotating.
[0019] By rotating, the thermostatic valve core 11 changes the size of the channel between the thermostatic valve core 11 and the guide tube 9, and at the same time changes the size of the channel at the connection position between the thermostatic valve core 11 and the cold water pipe 8.
[0020] Working principle: When needed, the user installs the outer casing 2, which provides support. Hot water is introduced through the check valve 3 and hot water pipe 4, and guided to the guide pipe 9. From there, it is guided to the thermostatic valve core 11. The cold water pipe 8 connects to the thermostatic valve core 11, introducing cold water. Under the control of the thermostatic handwheel 7, the ratio of hot and cold water can be adjusted, allowing the mixed water to flow through the thermostatic valve core 11. The water is then guided through the lower end of the guide pipe 9 and discharged into the gear valve core 10. The gear valve core 10, adjusted by rotating the gear handwheel 5, changes the water flow rate, allowing the water to be discharged through the first interface 1 and the second interface 6. Rotating the gear valve core 10 changes the size of the connection channel with the guide pipe 9, regulating the flow rate. Simultaneously, rotating the thermostatic valve core 11 changes the size of the connection channel with the guide pipe 9 and the cold water pipe 8, adjusting the ratio of hot and cold water and controlling the heat of the mixed water, thus completing the operation.
[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
