Description

Technical Field

[0001] The utility model relates to a bathroom faucet, in particular to a low-cost flow channel for a shower faucet. Background Art

[0002] The shower faucet is an important tool in the shower equipment. The shower faucet can control the water temperature, flow rate and switch the water outlet. The shower faucet includes a metal shell and a plastic flow channel arranged in the metal shell. One end of the plastic flow channel is provided with a thermostatic valve core that can mix cold water and hot water into warm water with a constant water temperature. The other end is provided with a water diverter valve core that can switch between different water outlets and is connected to the warm water outlet of the thermostatic valve core, so that the shower faucet can adapt to the shower needs of different users.

[0003] At present, the existing flow channel for shower faucets is shown in the Chinese utility model "Plastic flow channel for thermostatic faucet with multiple uses" with patent number CN202323575489.9 (authorization announcement number CN221824588U). The two ends of the flow channel body are respectively provided with a first end mounting cavity for installing a switch valve core or a water diversion valve core and a second end mounting cavity for installing a thermostatic valve core. The first end mounting cavity and the second end mounting cavity are connected by a mixing water channel, and three water outlets with different water outlet directions are provided on the flow channel body, so that the flow channel body can meet the user's various usage needs through the combination of the three water outlets.

[0004] Although the aforementioned shower faucet flow channel has a wider range of applications, the second end mounting cavity of the flow channel body requires a thermostatic valve core to be installed. Since the thermostatic valve core needs to accurately and stably control the water temperature, the thermostatic valve core is more complex in structure and more expensive to produce, which in turn increases the production cost of the shower faucet. Therefore, further improvements to the shower faucet are needed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a flow channel for a shower faucet capable of installing a temperature regulating valve core in response to the above-mentioned existing technical status.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: the flow channel for the shower faucet includes a flow channel body, and the side wall of the flow channel body is provided with a cold water inlet, a hot water inlet, and a front water outlet, an upper water outlet, and a lower water outlet for discharging mixed water. The right end of the flow channel body is provided with a first installation cavity for installing a water diversion valve core, and the front water outlet, the upper water outlet and the lower water outlet are indirectly connected with the first installation cavity, and is characterized in that: the left end of the flow channel body is provided with a second installation cavity for installing a thermostatic valve core, the bottom of the thermostatic valve core is provided with a positioning block, and a positioning groove corresponding to the positioning block is provided in the second installation cavity, and the thermostatic valve core is installed in the second installation cavity through the cooperation of the positioning block and the positioning groove, the second installation cavity and the first installation cavity are directly connected through the mixed water channel, and the cold water inlet and the hot water inlet are directly or indirectly connected with the second installation cavity.

[0007] In order to enable the cold water inlet and the hot water inlet to be directly or indirectly connected to the second installation cavity, preferably, a water inlet channel connected to the cold water inlet is provided in the flow channel body, and the two ends of the water inlet channel are respectively connected to the first installation cavity and the second installation cavity, so that the cold water inlet is indirectly connected to the second installation cavity through the water inlet channel, and the hot water inlet is provided on the side wall of the second installation cavity, so that the hot water inlet is directly connected to the second installation cavity. Cold water flows into the second installation cavity through the water inlet channel, so that the cold water can cool the flow channel body and prevent the shower faucet from overheating and scalding the user; hot water flows directly into the thermostatic valve core of the second installation cavity through the hot water inlet, avoiding hot water from flowing in the flow channel body and preventing the flow channel body from heating up. In addition, the two ends of the water inlet channel are respectively connected to the first installation cavity and the second installation cavity, which facilitates the processing of the water inlet channel and makes the processing technology of the flow channel body simpler.

[0008] To make the layout of the water inlet channel more reasonable, the water inlet channel preferably includes two sections of water inlet branches, which are interconnected and staggered. The two ends of the water inlet channel are connected to the first installation cavity and the second installation cavity. That is, the water inlet channel is longer in the flow channel body and occupies more space. Dividing the water inlet channel into two sections of water inlet branches, which are sequentially connected and staggered, makes the layout of the water inlet channel in the flow channel body more reasonable and the wall thickness of the flow channel body thicker.

[0009] To optimize the layout of the cold and hot water inlets, the cold and hot water inlets are preferably located on the rear wall of the flow channel body, near the first mounting cavity, and the hot water inlet is located on the rear wall of the second mounting cavity. Existing shower faucets often have the two water inlets located at the rear, connected to the cold and hot water pipes, and the outlets located at the front, top, or bottom for user access. Therefore, positioning the cold and hot water inlets toward the rear optimizes their layout.

[0010] In order to ensure that the water outlet of the flow channel body can meet the needs of users, preferably, a first water outlet channel and a second water outlet channel are further provided in the flow channel body, one end of each of the first water outlet channel and the second water outlet channel is connected to the first installation cavity, the other end of the first water outlet channel is connected to the front water outlet and the upper water outlet, and the other end of the second water outlet channel is connected to the lower water outlet. The front water outlet and the upper water outlet can be selectively blocked by a plug, so that the front water outlet or the upper water outlet can discharge mixed water. The front water outlet and the upper water outlet share a water outlet channel, and by providing a plug in the front water outlet or the upper water outlet, the fluid in the flow channel body can flow out only forward, upward, or downward, or flow out forward and upward, forward and downward, or upward and downward. Therefore, the three water outlets of the flow channel body can meet the needs of users for various uses through different combinations, making the flow channel body more applicable in shower products.

[0011] Compared with the prior art, the advantages of the present invention are: the shower faucet flow channel utilizes the second installation cavity to install the thermostatic valve core, and the cold water and hot water flowing in through the cold water inlet and the hot water inlet are mixed in the thermostatic valve core of the second installation cavity. The thermostatic valve core can adjust the mixing ratio of cold water and hot water to control the water temperature. The mixed water in the second installation cavity flows into the water diversion valve core of the first installation cavity through the mixing water channel, so that the mixed water flows out from one or two of the front water outlet, the upper water outlet, and the lower water outlet, thereby meeting the user's usage needs; and the thermostatic valve core has a lower cost than the constant temperature valve core, thereby reducing the cost of the shower faucet flow channel, increasing the company's profit margin, and improving the price advantage of shower equipment.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 6 Shown is the best embodiment of the present utility model.

[0020] like Figures 1 to 6 As shown, the flow channel for the shower faucet of this embodiment includes a flow channel body 1, a first installation cavity 11 for installing the water diversion valve core 2 is provided at the right end of the flow channel body 1, and a second installation cavity 12 for installing the thermostatic valve core 3 is provided at the left end of the flow channel body 1. A positioning block 31 is provided at the bottom of the thermostatic valve core 3, and a positioning groove 121 corresponding to the positioning block 31 is provided in the second installation cavity 12. Through the cooperation of the positioning block 31 and the positioning groove 121, the thermostatic valve core 3 is installed in the second installation cavity 12. The second installation cavity 12 and the first installation cavity 11 are directly connected through the water mixing channel 13, so that the thermostatic valve core 3 adjusts the mixing ratio of cold water and hot water in the second installation cavity 12. The mixed water can flow to the water diversion valve core 2 of the first installation cavity 11 through the water mixing channel 13, and the water diversion valve core 2 controls the water outflow direction of the mixed water.

[0021] In this embodiment, the side wall of the flow channel body 1 is provided with a cold water inlet 1a and a hot water inlet 1b. The cold water inlet 1a is provided on the rear wall of the flow channel body 1 near the first installation cavity 11, and the hot water inlet 1b is provided on the rear wall of the second installation cavity 12, so that the hot water inlet 1b is directly connected to the second installation cavity 12. Hot water flows directly into the temperature regulating valve core 3 of the second installation cavity 12 through the hot water inlet 1b, thereby preventing hot water from flowing within the flow channel body 1. Furthermore, a water inlet channel 14 is provided within the flow channel body 1, connected to the cold water inlet 1a. The two ends of the water inlet channel 14 are respectively connected to the first installation cavity 11 and the second installation cavity 12. This not only allows the cold water inlet 1a to be indirectly connected to the second installation cavity 12 through the water inlet channel 14, but also allows the cold water flowing in through the cold water inlet 1a to cool the flow channel body 1. The water inlet channel 14 includes two sections of water inlet branches 141 . The two sections of water inlet branches 141 are interconnected and staggered, so that the layout of the water inlet channel 14 in the flow channel body 1 is more reasonable.

[0022] The side wall of the flow channel body 1 of this embodiment is provided with a front water outlet 1c, an upper water outlet 1d, and a lower water outlet 1e for discharging mixed water. The front water outlet 1c, the upper water outlet 1d, and the lower water outlet 1e are indirectly connected to the first installation cavity 11. Specifically, a first water outlet channel 15 and a second water outlet channel 16 are also provided in the flow channel body 1 of this embodiment. One end of the first water outlet channel 15 and the second water outlet channel 16 are both connected to the first installation cavity 11, the other end of the first water outlet channel 15 is connected to the front water outlet 1c and the upper water outlet 1d, and the other end of the second water outlet channel 16 is connected to the lower water outlet 1e. The front water outlet 1c and the upper water outlet 1d can be selectively blocked by the plug 4, so that the front water outlet 1c or the upper water outlet 1d can discharge mixed water. The front water outlet 1c of this embodiment is blocked by the plug 4, so that the upper water outlet 1d can discharge mixed water.

[0023] The working process of this embodiment is as follows: hot water flows into the thermostatic valve core 3 of the second installation cavity 12 through the hot water inlet 1b, and cold water flows in through the cold water inlet 1a, and then flows into the thermostatic valve core 3 of the second installation cavity 12 through the water inlet channel 14. The thermostatic valve core 3 mixes the cold water and hot water in the required proportion. After mixing, the mixed water flows into the water diversion valve core 2 of the first installation cavity 11 through the water mixing channel 13. The water diversion valve core 2 controls the mixed water to flow out from one or two of the front water outlet 1c, the upper water outlet 1d, and the lower water outlet 1e.
