Technical Field

[0001] This invention relates to the field of shower faucets, and in particular to a thermostatic shower faucet. Background Technology

[0002] Chinese Patent Publication No. CN209688168U discloses a temperature-controlled shower faucet. The shower faucet includes a faucet body and a thermostatic valve core. The faucet body has a cold water inlet, a first water inlet, a water outlet, and a warm water chamber. The inlet and outlet of the warm water chamber are respectively connected to the cold water inlet, the first water inlet, and the water outlet. The thermostatic valve core is disposed in the warm water chamber. It also includes a multi-way adjustable valve and a mixing water channel, which is connected to the water outlet. The multi-way adjustable valve is installed in the faucet body between the cold water inlet, the first water inlet, and the inlet of the warm water chamber, and is connected to the mixing water channel. The multi-way adjustable valve is used to adjust the connection or complete closure of the cold and hot water inlets and the warm water chamber, or the mixing water channel.

[0003] In the aforementioned thermostatic shower faucet, the thermostatic valve and the multi-way switch valve are respectively located at the left and right ends of the faucet body, and the interfaces of the cold water pipe and the hot water pipe are both located at the rear of the faucet body. This structure is a common structure in the field. The problem with this structure is that only one thermostatic valve and one switch valve can be installed at the left and right ends of the faucet, and the number of thermostatic valves and switch valves cannot be increased, which limits the use of the shower faucet. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this invention is to provide a thermostatic shower faucet that is easy to install with multiple thermostatic valves and on / off valves, and has a wider range of applications.

[0005] The technical solution adopted by this invention to solve the problem is: a thermostatic shower faucet, comprising: The body has a thermostatic valve mounting hole and a multi-way switch valve mounting blind hole on its side wall. A thermostatic valve is installed in the thermostatic valve mounting hole, and a multi-way switch valve is installed in the multi-way switch valve mounting blind hole. The side wall of the body has a first water inlet and a second water inlet. The first water inlet is connected to the thermostatic valve, and the second water inlet is connected to the multi-way switch valve. The end of the body has a first water outlet, and the side of the body has a second water outlet. Both the first water outlet and the second water outlet can be connected to the multi-way switch valve.

[0006] The thermostatic valve mounting hole and the multi-way switch valve mounting blind hole are located on the side wall of the main body. The first water outlet and the second water outlet are respectively provided at the end and side of the main body. When the number of thermostatic valves and multi-way switch valves increases, it is only necessary to increase the number of thermostatic valve mounting holes and multi-way switch valve mounting blind holes on the side wall of the main body. Therefore, multiple water inlets are possible, not limited to one hot water inlet and one cold water inlet. Furthermore, multiple water inlets can be controlled to output water simultaneously by increasing the number of multi-way switch valves.

[0007] As a further improvement to the above technical solution, both the thermostatic valve mounting hole and the multi-way switch valve mounting blind hole are located on the front side of the main body, and both the first water inlet and the second water inlet are located on the lower side of the main body. The user can adjust the state of the multi-way switch valve from the front side of the main body to control the water flow from the first or second water outlet.

[0008] As a further improvement to the above technical solution, the left and right sides of the main body are each provided with blind holes for mounting the multi-way switch valve, and the thermostatic valve mounting hole is located between the two blind holes for mounting the multi-way switch valve; the left and right sides of the main body are each provided with a second water inlet, the left and right sides of the main body are each provided with a second water outlet, and both the left and right ends of the main body are provided with a first water outlet. This technical solution includes two first water outlets and two second water outlets, thus having four water outlet paths, which can provide mixed water to handheld shower heads, overhead shower heads, faucets, flushing hoses, etc., to meet various user needs.

[0009] As a further improvement to the above technical solution, the thermostatic valve includes a cold water inlet, a hot water inlet, and a mixed water outlet. The thermostatic valve mounting hole of the main body has a cold water inlet chamber, a hot water inlet chamber, and an outlet chamber. The cold water inlet is located in the cold water inlet chamber, the hot water inlet is located in the hot water inlet chamber, and the mixed water outlet is located in the outlet chamber. The bottom of the multi-way switch valve mounting blind hole has a first through hole, a second through hole, a third through hole, and a fourth through hole. The second inlet and the cold water inlet chamber are both connected to the first through hole. The mixed water outlet is connected to the multi-way switch valve mounting blind hole through the second through hole, the first outlet is connected to the multi-way switch valve mounting blind hole through the third through hole, and the second outlet is connected to the multi-way switch valve mounting blind hole through the fourth through hole. All water passages in the main body are connected to the multi-way switch valve. The bottom of the blind hole for installing the multi-way switch valve has a first through hole, a second through hole, a third through hole, and a fourth through hole, which are connected to the multi-way switch valve. Therefore, the opening and closing of each water passage in the main body can be controlled by controlling the multi-way switch valve.

[0010] As a further improvement to the above technical solution, the multi-way switch valve includes a valve body, a fixed plate assembly, and a rotating plate assembly; the fixed plate assembly has at least four water holes, which are respectively connected to a first through hole, a second through hole, a third through hole, and a fourth through hole; the rotating plate assembly has a channel and an inwardly opening blind hole, the channel and the blind hole are arranged opposite each other on the left and right sides, and the rotating plate assembly has an inner water inlet groove communicating with the channel on its circumference; the valve body is fixedly installed in the blind hole of the multi-way switch valve; the fixed plate assembly is fixedly installed in the inner end of the valve body, and the rotating plate assembly is rotatably installed in the valve body, with the inner end face of the rotating plate assembly fitting against the outer end face of the fixed plate; the valve body has an outer water inlet groove, which is always connected to the inner water inlet groove; when the rotating plate assembly rotates to the point where the channel communicates with one water hole, the blind hole can communicate with two adjacent water holes. The outer water inlet tank is used to connect to the second water inlet. The channel is used to introduce water from the outer water inlet tank and the inner water inlet tank into the body. The blind hole is used to connect two adjacent through holes, the first through hole, the second through hole, the third through hole and the fourth through hole, so as to connect the water outlet of the mixed water in the body.

[0011] As a further improvement to the above technical solution, the fixing plate assembly has five water holes, with a groove connecting two adjacent water holes. A connecting portion is provided in the groove, and a secondary connecting portion adapted to the connecting portion is provided in the main body. The fixing plate assembly is axially symmetrical, with its axis of symmetry passing through the groove. The multi-way valve mounting blind hole on the left and the multi-way valve mounting blind hole on the right of the main body are mirror images of each other. Because the multi-way valve mounting blind hole on the left and the multi-way valve mounting blind hole on the right of the main body are mirror images of each other, the first through hole, second through hole, third through hole, and fourth through hole at the bottom of the two multi-way valve mounting blind holes are also mirror images of each other. A fixing plate assembly adapted to one multi-way valve mounting blind hole can be adapted to the other multi-way valve mounting blind hole after rotating 180°. The advantage of the left and right sides of the main body being mirror images also includes that two second water inlets can be simultaneously located on the upper or lower side of the main body, facilitating connection between the main body and external water pipes.

[0012] As a further improvement to the above technical solution, a decorative cover is fixedly installed on the front end of the rotating plate assembly, and the shape and size of the decorative cover are consistent with the front part of the outer shell of the thermostatic valve.

[0013] As a further improvement to the above technical solution, it also includes a housing, the main body is disposed inside the housing, the housing is provided with a connection hole, and a sealing ring is provided in the connection hole; the main body includes multiple connectors, the second water inlet, the first water inlet, the first water outlet and the second water outlet are all located at the outer end of the connector, the outer end of the connector is connected to the connection hole through the sealing ring, and the connection hole is used to connect an external water inlet pipe or water outlet pipe.

[0014] As a further improvement to the above technical solution, the outer shell includes a bottom cover, a middle frame, and a front cover. The connecting hole portion is located on the edge of the bottom cover, and the other portion of the connecting hole is located on the edge of the middle frame. The middle frame is fixedly connected to the bottom cover, and the front cover is snapped into the middle frame.

[0015] As a further improvement to the above technical solution, the bottom cover is provided with an outwardly protruding connecting portion, and the connecting portion is provided with a connecting hole. The bottom cover is used to connect to the wall.

[0016] The beneficial effects of this invention are: the thermostatic valve mounting hole and the multi-way switch valve mounting blind hole are provided on the side wall of the main body, and the first water outlet and the second water outlet are respectively provided at the end and the side of the main body. When the number of thermostatic valves and multi-way switch valves increases, it is only necessary to increase the number of thermostatic valve mounting holes and multi-way switch valve mounting blind holes on the side wall of the main body. Therefore, multiple water inlets are possible, not limited to one hot water inlet and one cold water inlet. Furthermore, multiple water outlets can be controlled to exit simultaneously by increasing the number of multi-way switch valves. Attached Figure Description
