Description

Technical Field

[0001] This invention relates to the field of shower device technology, and more specifically, to a multifunctional connecting valve and a shower device. Background Technology

[0002] Shower units are the most commonly used shower equipment in daily life. After use, a large amount of water usually remains in the water pipes connecting the hand shower, overhead shower, faucet, and wall. In some cold regions, this residual water can freeze, causing blockages and preventing water from flowing out; it can even damage valves and other components, affecting their lifespan and resulting in a poor user experience. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a multifunctional connecting valve and a shower device to solve the above problems.

[0004] The present invention adopts the following solution:

[0005] This application provides a multifunctional connecting valve for connecting a shower device. It includes a main body with an inlet channel, an outlet channel, and a drain channel. The lower end of the main body has an inlet section connected to the inlet and outlet channels, which is used to connect to an external water circuit. The main body also has an outlet section connected to the outlet channel, located above the inlet section, which can be used to connect to an external shower device. The main body has an installation cavity containing a switching valve core, which controls the connection between the outlet channel and either the inlet channel or the drain channel.

[0006] Furthermore, the water inlet and the water outlet extend in opposite directions relative to the main body.

[0007] Furthermore, the water inlet and the water outlet are arranged radially along the main body.

[0008] Furthermore, the mounting cavity is located at the upper end of the main body and forms an upper opening.

[0009] Furthermore, the drainage channel extends axially through the main body.

[0010] Furthermore, the water inlet and the water outlet are provided with external threads.

[0011] This application also provides a shower device, including a body, on which at least a handheld shower head and / or an overhead shower head are connected; the body is connected to an external water circuit via the aforementioned multi-functional connecting valve.

[0012] Furthermore, the switching valve core is provided with a switching element, which is used to control the movement of the switching valve core, thereby controlling the water outlet channel to be connected to one of the water inlet channel or the water outlet channel, and at least part of the operating part of the switching element is higher than the upper end surface of the body.

[0013] Furthermore, the main body is provided with multiple water channels that are respectively connected to the handheld shower head, the overhead shower head and the water faucet, as well as a water channel switching valve to realize water channel switching.

[0014] Furthermore, the two multi-functional connecting valves connected to the main body are arranged at an angle.

[0015] By adopting the above technical solution, the present invention can achieve the following technical effects: This multi-functional connecting valve, through its drainage channel and switching valve core, can discharge residual water in the downstream pipeline, thereby preventing freezing. It effectively prevents residual water inside the downstream water outlet from freezing, avoiding pipeline rupture and component damage, and improving the service life and reliability of the device. At the same time, this multi-functional connecting valve can also act as a water stop, that is, when it is necessary to replace or repair the downstream water outlet, the connection status of the water circuit can be switched by simply switching the connection status of the water circuit through this multi-functional connecting valve to close the external water circuit, without having to shut off the main water valve.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example Combination Figures 1 to 3 As shown, this embodiment provides a multi-functional connecting valve, including a main body 3 with an inlet channel 6, an outlet channel 7 and a drain channel 8. The lower end of the main body 3 is provided with an inlet part 4 connected to the inlet and outlet channels 6, and the inlet part 4 is used to connect to an external water circuit. The main body 3 is provided with an outlet part 5 connected to the outlet channel 7. The outlet part 5 is located above the inlet part (4) and can be used to connect to an external shower device. The main body 3 is provided with an installation cavity 14, and the installation cavity 14 is provided with a switching valve core 9. The switching valve core 9 is used to control the outlet channel 7 to connect with either the inlet channel 6 or the drain channel 8.

[0020] This multi-functional connecting valve, through its drainage channel and switching valve core, can discharge residual water in the downstream pipeline, thereby preventing freezing. It effectively prevents residual water inside the downstream water outlet from freezing, avoiding pipeline rupture and component damage, and improving the service life and reliability of the device. At the same time, this multi-functional connecting valve can also act as a water stop, that is, when it is necessary to replace or repair the downstream water outlet, the connection status of the water circuit can be switched by simply switching the connection status of the water circuit through this multi-functional connecting valve to close the external water circuit, without having to shut off the main water valve.

[0021] It should be noted that the water inlet 4 mentioned above is located at the lower end of the main body 3, and it is in a relative position to the water outlet 5, and is limited to the lower end face or lower side of the main body 3.

[0022] In this embodiment, a shower device is used as a specific example for illustration. The shower device includes a body, which is connected to an external water circuit through the multi-functional connecting valve.

[0023] Specifically, the shower device includes a handheld shower head (not shown in the attached drawings), an overhead shower (not shown in the attached drawings), and a water faucet 10; a water path switching valve 11 is provided on the main body 1 to switch the water path between the handheld shower head, the overhead shower, and the water faucet 10. The water faucet 10 is located on the left side of the main body 1; the main control valve 12 is located on the right side of the main body 1; and the water path switching valve 11 is located in the middle of the main body 1.

[0024] The switching valve core 9 enables flexible switching of the water flow path, allowing the shower device to switch to a state where the water outlet channel 7 and the drain channel 8 are connected after use in cold regions, thereby draining residual water from inside the shower device. It should be noted that in this embodiment, the main control valve 12 needs to be opened to drain water from the downstream pipe. For shower devices with multiple water outlets such as the handheld shower head, overhead shower, or faucet 10, the water path switching valve 11 needs to be operated to switch the water paths during drainage, draining residual water from each path. This solution effectively avoids pipe blockage, water outages, and valve and component damage caused by frozen residual water, thus extending the equipment's service life. Meanwhile, when the switching valve core 9 of the multi-functional connecting valve is switched to the state where the water outlet channel 7 and the drainage channel 8 are connected, the water inlet channel 6 is in the closed state, which means it has the function of stopping water flow. When the water outlet device downstream of the multi-functional connecting valve is repaired or replaced, there is no need to shut off the main valve of the water circuit, which makes it convenient for users to quickly shut off the water circuit for repair and replacement work.

[0025] In this embodiment, the water inlet 4 and the water outlet 5 are arranged radially along the main body 3. The water inlet 4 and the water outlet 5 are provided with external threads. This greatly simplifies the pipe layout, avoids complex bends and transitions, and allows for better connection of cold water inlet pipes and hot water inlet pipes on the wall, as well as the cold water inlet and hot water inlet on the main body 1. Figure 1 As shown, the angle of the multi-functional connecting valve can be adjusted so that the multi-functional connecting valve is tilted, thereby enabling better adaptation and connection between the cold water inlet and the cold water inlet pipeline, and between the hot water inlet and the hot water inlet pipeline.

[0026] In this embodiment, the drainage channel 8 extends axially through the body 3. The drainage channel 8 extends to the bottom region of the body 3, allowing accumulated water to drain smoothly along the axial channel by gravity.

[0027] In this embodiment, a switching element 13 is provided on the switching valve core 9, which is used to control the operation of the switching valve core 9, thereby controlling the connection between the water outlet channel and either the water inlet channel or the water outlet channel. At least a portion of the operating part of the switching element 13 is higher than the upper surface of the body 1. This effectively solves the problem of inconvenient operation caused by the operating parts of the switching valve core 9 being inconspicuous or difficult to access.
