Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, and in particular to a plastic flow channel for easy replacement of a hydroelectric generator. Background Technology

[0002] In bathroom fixtures, the application of hydroelectric generators has become an important way to utilize green energy, using the kinetic energy generated by water flow to generate electricity to power bathroom fixtures. Currently, existing hydroelectric generators are usually installed in the plastic flow channels of bathroom fixtures. An example of the existing technology used in bathroom fixtures' plastic flow channels is shown in Chinese Utility Model Patent No. CN202322027144.3 (Authorization Announcement No. CN220580119U). The main body of this shower device includes a pre-embedded box, a valve body with a mixing chamber, and a panel. The upper and lower parts of the valve body are respectively provided with hot water inlet channels and cold water inlet channels. The interior of the valve body has a main flow channel connected to the mixing chamber. The main body has a first outlet, a second outlet, and a third outlet. The front end of the main body has a first button switch, a second button switch, and a third button switch to control the opening and closing of the first, second, and third outlets, respectively. A hydroelectric generator is installed on the valve body, with the generator's impeller located within the main flow channel. A display screen electrically connected to the hydroelectric generator is installed on the outer surface of the mixing valve.

[0003] Although the aforementioned plastic flow channel can be electrically connected to the display screen via a water generator to show the water temperature of the shower equipment, the water generator and valve body are located inside the main body of the shower unit, and the water generator is situated between the on / off valve and the first button switch. Therefore, the entire water generator is concealed within the shower unit's embedded box and panel. When the water generator malfunctions and requires repair, workers need to disassemble the shower unit's panel and embedded box to replace it, making the replacement of the water generator in this plastic flow channel rather cumbersome. Therefore, further improvements are needed for plastic flow channels with integrated water generators. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a plastic flow channel with a reasonable structure and easy replacement of the hydroelectric generator, in view of the above-mentioned existing technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: the plastic flow channel for easy replacement of a hydroelectric generator includes a flow channel body integrally molded from plastic material. One end of the flow channel body is provided with a first mounting cavity for installing a mixing valve core. The rear side of the flow channel body is provided with a hot water inlet and a cold water inlet communicating with the first mounting cavity. The flow channel body is also provided with a mixing flow channel communicating with the first mounting cavity. The flow channel body is provided with outlets at least at the top and bottom. The mixing flow channel is directly or indirectly connected to each outlet of the flow channel body. The feature is that: the bottom of the flow channel body is provided with a second mounting cavity for installing a hydroelectric generator. The hydroelectric generator is detachably installed in the second mounting cavity, and the mixing flow channel is connected to the second mounting cavity.

[0006] To achieve indirect communication between the mixing channel and the various outlets of the channel body, preferably, the channel body also includes an outlet channel, with each outlet of the channel body connected to the outlet channel, which in turn connects to the second mounting cavity. Each outlet is indirectly connected to the mixing channel via the outlet channel and the second mounting cavity, allowing the water mixed in the plastic channel to flow out through the outlet.

[0007] To facilitate the machining of the flow channel body, preferably, the top of the flow channel body has an upper opening, and the front end of the flow channel body has a front opening. The upper opening communicates with the mixing water flow channel, and the front opening communicates with the second mounting cavity. Plugs are provided inside the upper opening and the front opening. The upper opening and the front opening facilitate the machining of the mixing water flow channel and the second mounting cavity within the flow channel body and enable communication between the mixing water flow channel and the second mounting cavity. The plugs prevent water from flowing out from the upper opening and the front opening.

[0008] In order to enable the hot water inlet and the cold water inlet to communicate with the first mounting cavity, preferably, the flow channel body is provided with a hot water inlet flow channel and a cold water inlet flow channel, the two ends of the hot water inlet flow channel are respectively connected to the hot water inlet and the first mounting cavity, and the two ends of the cold water inlet flow channel are respectively connected to the cold water inlet and the first mounting cavity.

[0009] Furthermore, the hot water inlet is positioned close to the first mounting cavity, while the cold water inlet is positioned away from the first mounting cavity. Positioning the hot water inlet close to the first mounting cavity and the cold water inlet away from the first mounting cavity lowers the temperature of the plastic flow channel, preventing burns to the user due to excessively high temperatures.

[0010] To enable the plastic flow channel to adapt to shower devices with multiple water outlet methods, preferably, the flow channel body includes multiple water outlets, including a first water outlet, a second water outlet, and a third water outlet. The front end of the flow channel body is provided with a first switch, a second switch, and a third switch to control the opening and closing of the first water outlet, the second water outlet, and the third water outlet, respectively. The plastic flow channel has three water outlets, which can be connected to different shower devices.

[0011] Furthermore, the first and third water outlets are positioned downwards at the bottom of the flow channel body, while the second water outlet is positioned upwards at the top of the flow channel body. The upward-facing second water outlet is connected to the overhead spray, while the downward-facing first and third water outlets are connected to the lower water outlet and the handheld shower head, respectively.

[0012] Furthermore, the front end of the flow channel body is also provided with a switch valve core, and the flow channel body is also provided with a fourth water outlet controlled by the switch valve core to open and close, the fourth water outlet being connected to the mixing water flow channel. The switch valve core can control the flow rate of the water.

[0013] Compared with the prior art, the advantages of this utility model are as follows: the water generator of the plastic flow channel is installed in the second mounting cavity at the bottom of the flow channel body. The second mounting cavity is connected to the mixing water flow channel. The water flow in the mixing water flow channel can act on the water generator to generate electricity. When the user needs to replace the water generator, he only needs to remove the bottom of the outer shell to remove the water generator for replacement, thereby simplifying the operation steps of replacing the water generator in the plastic flow channel and facilitating the actual operation of the staff.

The hot water inlet 1a is located close to the first mounting cavity 11, and the cold water inlet 1b is located away from the first mounting cavity 11, so as to reduce the temperature of the outer shell of the flow channel body 1. Furthermore, the hot water inlet 1a and the cold water inlet 1b are arranged rearward to facilitate their connection with the water pipes embedded in the wall.

[0023] In this embodiment, the flow channel body 1 is also provided with a mixing water flow channel 12 that communicates with the first mounting cavity 11. The bottom of the flow channel body 1 is provided with a second mounting cavity 13 for the installation of the hydraulic generator 3.

Furthermore, the main body 1 of this embodiment is also provided with a water outlet channel 14. Each water outlet of the main body 1 is connected to the water outlet channel 14. The water outlet channel 14 is connected to the second mounting cavity 13. Each water outlet is indirectly connected to the mixing channel 12 through the water outlet channel 14 and the second mounting cavity 13, so that the water that has been mixed in the plastic channel can flow out through the water outlet. The top of the main body 1 is provided with an upper opening 1c, and the front end of the main body 1 is provided with a front opening 1d. The upper opening 1c is connected to the mixing channel 12, and the front opening 1d is connected to the second mounting cavity 13. The upper opening 1c and the front opening 1d are provided with plugs 4. The upper opening 1c and the front opening 1d are provided to facilitate the processing of the mixing channel 12 and the second mounting cavity 13 in the main body 1 and to enable the mixing channel 12 to be connected to the second mounting cavity 13.

[0024] In addition, the flow channel body 1 of this embodiment includes multiple water outlets, including a first water outlet 1e, a second water outlet 1f, and a third water outlet 1g.

The second water outlet 1f is arranged upwards at the top of the flow channel body 1, connecting to the overhead shower head of the shower equipment. Furthermore, the front end of the flow channel body 1 of this embodiment is also provided with a switch valve core 8, and the flow channel body 1 is also provided with a fourth water outlet 1h, controlled by the switch valve core 8, which connects to the mixing channel 12.

[0025] The workflow of this embodiment is as follows: hot water flows through the hot water inlet 1a and the hot water inlet channel 15 into the first mounting cavity 11, and cold water flows through the cold water inlet 1b and the cold water inlet channel 16 into the first mounting cavity 11. The hot water and cold water are mixed in a certain proportion in the mixing valve core 2 in the first mounting cavity 11. The mixed water flows through the mixing channel 12 into the second mounting cavity 13. The flow of the mixed water drives the water generator 3 to operate, enabling the water generator 3 to generate electricity to power the shower equipment. The mixed water in the second mounting cavity 13 flows through the water outlet channel 14 into the first water outlet 1e, the second water outlet 1f, and the third water outlet 1g. The user controls the first switch 5, the second switch 6, or the third switch 7 to make the mixed water flow out from the first water outlet 1e, the second water outlet 1f, and the third water outlet 1g. The user can also control the switch valve core 8 to adjust the water flow rate or turn the shower equipment on and off.
