[0002] At present, bathing equipment is a common household appliance in people's daily life. Bathing equipment is divided into electric bathing equipment, gas bathing equipment, solar bathing equipment, etc. Among them, when used at home, a mixing valve is usually configured to mix the hot water output by the bathing equipment with the cold water in the tap, and finally output hot water with appropriate temperature from the faucet or shower.

[0003] When bathing equipment is used at home, it is usually used together with a mixing valve and a shower head. Chinese patent publication number CN 105310580 A discloses a bathing equipment equipped with a water purification device to filter and purify the bathing water. However, since the mixing valve is always connected to the municipal pipe network, when the mixing valve is damaged, water leakage will occur, resulting in reduced reliability.

[0004] In view of this, how to design a technology to reduce the occurrence of serious water leakage to improve the reliability of use is the technical problem to be solved by the present invention. Summary of the invention

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0060] Embodiment 1, as Figure 1-Figure 7 As shown, the bathing equipment of this embodiment includes:

[0061] The housing 400 is provided with two water inlet pipes 401 and one water outlet pipe 402 .

[0062] The water treatment module 100 is used to treat the water quality of the incoming water.

[0063] The water mixing valve 200 is provided with a hot water inlet (not shown), a cold water inlet (not shown) and a mixed water outlet (not shown), wherein one water inlet pipe 401 is connected to the hot water inlet of the water mixing valve to input hot water, another water inlet pipe 401 is connected to the cold water inlet of the water mixing valve to input cold water, and the mixed water outlet is connected to the water treatment module 100 to transport water of suitable temperature to the inside of the water treatment module 100. After being processed by the water treatment module 100, the water is output from the water outlet pipe 402.

[0064] In order to reduce the serious water leakage caused by the damage of the water treatment module 100 or the mixing valve 200 in the housing 400 , a water leakage prevention device 500 may be installed on the two water inlet pipes 401 and one water outlet pipe 402 .

[0065] Specifically, the anti-leakage device 500 includes two first water pipes 5100, a second water pipe 5200, a pressure on-off valve 5300 and a three-way connecting pipe 5400. The first water pipe 5100 is provided with a first water inlet pipe head 5101, a first connecting pipe head 5102 and a first water outlet pipe head 5103. The first water pipe 5100 is also provided with a first connecting flow channel 5104. The first port of the first connecting flow channel 5104 is connected to the first water inlet pipe head 5101, and the second port of the first connecting flow channel 5104 is connected to the first water outlet pipe head 5103. The second water pipe 5200 is provided with a first connecting flow channel 5104 connected to each other. The second water inlet pipe head 5201, the second connecting pipe head 5202 and the second water outlet pipe head 5203 are connected, and the second water inlet pipe head 5201 is provided with a one-way valve 5208, and the one-way valve is used to control the one-way flow of water from the second water inlet pipe head 5201 to the second water pipe 5200; the pressure on-off valve 5300 is arranged in the corresponding first connecting pipe head 5102 and is used to switch the port two of the first connecting flow channel 5104 according to the water pressure at the first connecting pipe head 5102; the second connecting pipe head 5202 is connected to the first connecting pipe head 5102 respectively through the three-way connecting pipe 5400.

[0066] During assembly, the first water outlet pipe head 5103 of the first water pipe 5100 is connected to the outside of the corresponding water inlet pipe 401 , and the second water inlet pipe head 5201 of the second water pipe 5200 is connected to the water outlet pipe 402 .

[0067] For the pressure on-off valve 5300 in the first three-way connecting pipe head, it can perform corresponding actions according to the water pressure in the first three-way connecting pipe head and the pressure generated between the port two of the first connecting channel 5104 to achieve the purpose of preventing water leakage.

[0068] During use, usually, conventional bathing equipment is equipped with an inlet pipe 401 and an outlet pipe 402 for connecting to an external water pipe. During installation, the first outlet pipe head 5103 is connected to the corresponding inlet pipe 401 of the bathing equipment, and the second inlet pipe head 5201 is connected to the outlet pipe 402.

[0069] When the user uses water through the water terminal, the second water pipe 5200 is connected to the water terminal through the second water outlet pipe to output water upward. At this time, the water pressure in the second water pipe 5200 is lower than the water pressure at the first water inlet pipe head 5101. At the same time, the first three-way connecting pipe head is connected to the second three-way connecting pipe head through the three-way connecting pipe 5400, so that the water pressure at the first three-way connecting pipe head is also reduced accordingly. The water introduced from the first water inlet pipe head 5101 is output through the pressure on-off valve 5300 opened at the second port of the first connecting flow channel 5104 and finally flows into the bathing equipment through the first water outlet pipe head 5103.

[0070] After the user turns off the water terminal, the tap water pressure of the external water supply pipe is transmitted to the second water pipe 5200, and the water pressure of the first three-way connecting pipe head gradually increases and eventually becomes the same as the water pressure in the first water inlet pipe head 5101. At this time, the pressure on-off valve 5300 will automatically reset to close port two of the first connecting channel 5104.

[0071] At this time, if the bathing equipment itself is broken and leaking, since the second water inlet pipe head 5201 of the second tube body is equipped with the one-way valve, leakage at the water terminal will not cause changes in the water pressure in the second tube body, and the pressure on-off valve 5300 is always in a state of closing port 2 of the first connecting channel 5104. Ultimately, when the bathing equipment is damaged, tap water will not be input into the bathing equipment to cause serious leakage.

[0072] By configuring a pressure on-off valve in the first water pipe, the pressure on-off valve is completely built into the first water pipe, the first water pipe is connected to the water supply pipe (tap water pipe) in the user's home through the first water inlet pipe head, the first water pipe and the second water pipe are respectively installed on the bathing equipment in the user's home, and when the bathing equipment is in use, the water introduced into the first water pipe is processed by the bathing equipment and then output from the second water pipe. At this time, since the three-way connecting pipe connects the first connecting pipe head and the second connecting pipe head, the water pressure in the first connecting pipe head is lower than the water pressure in the first water inlet pipe head. At this time, the pressure on-off valve opens the port two of the first connecting flow channel to connect the first water inlet pipe head and the first water outlet pipe head to realize water supply. When the bathing device is in the water-off state, the water pressures in the first water pipe and the second water pipe gradually become the same, so that the water pressures in the first water inlet pipe head and the first connecting pipe head are balanced. At this time, the pressure on-off valve automatically resets and closes the second port of the first connecting flow channel. In the event of water leakage inside the bathing device, since the second water inlet pipe head is provided with a one-way valve, the water pressures in the first water inlet pipe head and the first connecting pipe head remain balanced, thereby ensuring that the water supply pipe will not output water from the first water pipe, thereby reducing leakage accidents and improving the reliability of the appliance.

[0073] In some embodiments, for the pressure on-off valve 5300, it mainly relies on the water pressure difference between the first water inlet pipe head 5101 and the first three-way connecting pipe head to achieve mechanical on-off control. To this end, the pressure on-off valve 5300 may include a spring 5301 and a flexible sealing component 5302, the flexible sealing component 5302 is arranged in the first connecting pipe head 5102 and is used to switch the port 2 of the first connecting flow channel 5104, and the spring 5301 is arranged in the first connecting pipe head 5102 and is used to apply an elastic force toward the port 2 of the first connecting flow channel 5104 to the flexible sealing component 5302.

[0074] Specifically, the flexible sealing component 5302 is arranged opposite to the second port of the first connecting flow channel 5104 and is used to block the second port of the first connecting flow channel 5104. The flexible sealing component 5302 is subjected to the water pressure in different pipe heads on both sides of the first three-way connecting pipe head, thereby deforming according to the pressure difference, thereby opening and closing the second port of the first connecting flow channel 5104.

[0075] When the user uses water through the water terminal, the water pressure in the first three-way connecting pipe head decreases. Under the action of the water pressure at the second port of the first connecting channel 5104, the flexible sealing component 5302 will be deformed to open the second port of the first connecting channel 5104. The water entering the first water pipe 5100 from the first water inlet pipe head 5101 is output from the second port of the first connecting channel 5104 and finally flows into the bathing equipment from the first water outlet pipe head 5103.

[0076] When the user closes the water terminal and stops using water, the water pressure in the first three-way connecting pipe head gradually rises and gradually offsets the water pressure generated by port two of the first connecting channel 5104. In addition, under the action of the spring 5301, the flexible sealing component 5302 is deformed toward port two of the first connecting channel 5104 and finally blocks port two of the first connecting channel 5104.

[0077] In certain embodiments, in order to facilitate the installation of the flexible sealing component 5302, the flexible sealing component 5302 is formed with a sealing portion 53021, an elastic deformation portion 53022 and an installation and fixing portion 53023, the elastic deformation portion 53022 is connected between the sealing portion 53021 and the installation and fixing portion 53023, the sealing portion 53021 is arranged opposite to the port 2 of the first connecting channel 5104, and the installation and fixing portion 53023 is arranged on the inner wall of the first connecting pipe head 5102.

[0078] Specifically, the sealing portion 53021 formed by the flexible sealing component 5302 is used to block the second port of the first connecting channel 5104, the elastic deformation portion 53022 is used to meet the requirement that the sealing portion 53021 can open and close the second port of the first connecting channel 5104 under different water pressures, and the mounting and fixing portion 53023 is used to be installed in the first three-way connecting pipe head.

[0079] In some embodiments, the pressure on-off valve 5300 also includes a mounting support 5303, which is disposed in the first three-way connecting pipe head, and a spring 5301 is disposed between the mounting support 5303 and the sealing portion 53021, and the spring 5301 is used to apply an elastic force to the sealing portion 53021 in a direction toward port 2 of the first connecting channel 5104.

[0080] Specifically, in order to facilitate the installation of the spring 5301 in the first three-way connecting pipe head, a mounting support 5303 can be set in the first three-way connecting pipe head by means of threaded connection or interference fit, and the mounting support 5303 is used to support the spring 5301 so that the spring 5301 can provide effective elastic force to the sealing part 53021.

[0081] Among them, the mounting support 5303 includes an outer sleeve 53031 and an inner sleeve 53032, the outer sleeve 53031 is sleeved on the outside of the inner sleeve 53032, and a water flow channel 53033 is formed between the outer sleeve 53031 and the inner sleeve 53032; the outer sleeve 53031 is threadedly connected in the first three-way connecting pipe head, and the spring 5301 is arranged in the inner sleeve 53032.

[0082] Specifically, during assembly, the outer sleeve 53031 is installed in the first three-way connecting pipe head by means of threaded connection. Since the outer sleeve 53031 and the inner sleeve 53032 are connected to each other, the inner sleeve 53032 can be used to support the installation spring 5301.

[0083] The outer sleeve 53031 and the inner sleeve 53032 can be connected by a connecting rod to achieve the inner sleeve 53032 being suspended in the outer sleeve 53031, thereby forming a water flow channel 53033.

[0084] The water flow channel 53033 can satisfy the water pressure in the three-way connecting pipe 5400 and directly transmit it to the flexible sealing component 5302 to ensure that the water path is unobstructed and that the water pressure can be accurately transmitted.

[0085] In some embodiments, in order to fix and install the flexible sealing component 5302 , a mounting ring 5105 is provided in the first water pipe 5100 , and the mounting fixing portion 53023 is clamped between the mounting ring 5105 and the outer sleeve 53031 .

[0086] Specifically, a mounting ring 5105 is provided on the inner wall of the first water pipe 5100 at one side of the first connecting flow channel 5104 , and the mounting ring 5105 cooperates with the outer sleeve 53031 to fix the flexible sealing component 5302 .

[0087] During the assembly process, the flexible sealing component 5302 is placed into the first three-way connecting pipe head and abutted against the mounting ring 5105. Then, the outer sleeve 53031 is inserted into the first three-way connecting pipe head.
