Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a combined shower faucet. Background Technology

[0002] Shower faucets are an essential accessory in bathroom fixtures. They are mainly manufactured by one-piece casting, making them sturdy and durable. However, their production cost is too high, and they are prone to corrosion after prolonged use, affecting water quality. Therefore, a modular shower faucet has emerged on the market, mainly composed of injection-molded water-passing components and a protective shell. However, the protective shell and water-passing components of this type of faucet are mostly one-piece molded, resulting in higher manufacturing costs. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model proposes a combined shower faucet.

[0004] To achieve the above objectives, the present invention provides a combined shower faucet, comprising: a housing and a valve core disposed within the housing. The valve core includes: a valve seat, a water outlet hole and at least one water inlet hole on the valve seat, a water outlet seat disposed on the valve seat and communicating with the water outlet hole, and a water inlet seat disposed on the valve seat and communicating with the water inlet hole. The housing is provided with a water outlet groove and a water inlet groove corresponding to the water outlet seat and the water inlet seat. A water inlet shell is fixedly disposed on the water inlet groove. The water inlet shell is provided with an installation groove for easy connection with a water supply pipe. A leak-proof device is also provided between the water inlet shell and the water inlet seat.

[0005] A further improvement is that the leak-proof device includes: a leak-proof pipe, several first sealing grooves formed on the leak-proof pipe, and a first sealing ring set in the first sealing groove. The leak-proof pipe is inserted into the water inlet seat, and a positioning device is also provided between the leak-proof pipe and the water inlet shell.

[0006] A further improvement is that the positioning device includes: a connecting seat set on the leak-proof pipe corresponding to the installation groove, and a positioning tube passing through the installation groove and locked on the connecting seat, wherein the positioning tube has a threaded hole for connecting the water supply pipe.

[0007] A further improvement is that the leak-proof pipe is also provided with a first reinforcing rib that abuts against the side wall of the water inlet shell, and the leak-proof pipe is also provided with a second reinforcing rib that abuts against the inner wall of the water inlet shell.

[0008] A further improvement is that a second sealing groove is provided on the connecting seat at the point where the positioning tube and the connecting seat abut, and a second sealing ring is provided in the second sealing groove.

[0009] A further improvement is that the valve seat is also provided with a sleeve that matches the housing, and the sleeve is provided with connecting threads for installing the valve core.

[0010] A further improvement is that the bottom of the water outlet seat is also provided with a third reinforcing rib that abuts against the bottom of the shell.

[0011] A further improvement is that the water inlet tank is matched with the water inlet shell, and the water inlet shell is inserted into the housing.

[0012] A further improvement is that the valve core is also provided with a third sealing groove that matches the port of the water inlet shell.

[0013] A further improvement is that a third sealing ring is provided inside the third sealing groove.

[0014] A further improvement is that the water inlet shell is welded to the outer shell.

[0015] A further improvement is that there are two water inlets, and the water inlet seat is configured to match the water inlets.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] 1. Low production cost: The faucet shell is assembled by welding, which has a lower production cost compared to a one-piece molded shell.

[0018] 2. Equipped with a leak-proof device, the water circuit and the housing are independent of each other, which avoids direct contact between the fluid and the housing, the inlet shell, and the weld points. It has a strong sealing feature, prevents fluid corrosion of the housing, and extends service life.

[0019] 3. Since the fluid does not come into direct contact with the shell, the technical requirements for welding personnel are low. It is only necessary to ensure a stable connection between the shell and the water inlet shell. Furthermore, there is no need to conduct leakage inspections on the shell afterward, which optimizes the production process and improves production efficiency.

[0020] 4. The shell and valve core, and the inlet shell and leak-proof pipe are connected by reinforcing ribs. This not only improves the strength of the leak-proof pipe and valve core, but also creates a certain gap between them and the shell and inlet shell to prevent heat from being transferred to the surface of the shell and inlet shell when hot water is input, thus improving the safety of use.

[0021] 5. The valve core and inlet shell are made of materials that are resistant to high and low temperatures and do not corrode (such as food-grade plastics), which improves the safety of the faucet.

[0022] 6. The faucet's shell is not a single piece but is composed of various parts, which facilitates modular production for manufacturers, thereby enriching the product line at a low cost and improving production convenience. Attached Figure Description

Detailed Implementation

[0032] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0033] like Figures 1-8As shown, a combined shower faucet includes: a housing 101 and a valve core 102 disposed within the housing 101. The valve core 102 includes: a valve seat 103, a water outlet 104 and at least one water inlet 105 disposed on the valve seat 103, a water outlet seat 106 disposed on the valve seat 103 and communicating with the water outlet 104, and a water inlet seat 107 disposed on the valve seat 103 and communicating with the water inlet 105. The housing 101 is provided with a water outlet groove 108 and a water inlet groove 109 corresponding to the water outlet seat 106 and the water inlet seat 107. A water inlet shell 110 is fixedly disposed on the water inlet groove 109. The water inlet shell 110 is provided with an installation groove 111 for easy communication with a water supply pipe. A leak-proof device is also provided between the water inlet shell 110 and the water inlet seat 107.

[0034] In order to allow the fluid to flow through the inlet housing 110 without contacting it and directly into the valve core 102, the leak-proof device includes: a leak-proof pipe 112, a plurality of first sealing grooves 113 formed on the leak-proof pipe 112, and a first sealing ring (not shown in the figure) set in the first sealing grooves 113. The leak-proof pipe 112 is inserted into the inlet seat 107, and a positioning device is also provided between the leak-proof pipe 112 and the inlet housing 110.

[0035] In order to position the water inlet pipe between the water inlet shell 110 and the valve core 102, the positioning device includes: a connecting seat 114 on the leak-proof pipe 112 corresponding to the mounting groove 111, and a positioning pipe 115 passing through the mounting groove 111 and locked on the connecting seat 114. The positioning pipe 115 has a threaded hole 116 for connecting the water supply pipe.

[0036] To enhance the strength of the leak-proof pipe 112 and improve its stability after positioning, the leak-proof pipe 112 is also provided with a first reinforcing rib 117 that abuts against the side wall of the water inlet shell 110, and the leak-proof pipe 112 is also provided with a second reinforcing rib 118 that abuts against the inner wall of the water inlet shell 110.

[0037] To prevent fluid leakage between the connector 114 and the positioning tube 115, a second sealing groove 119 is provided on the connector 114 at the abutment point between the positioning tube 115 and the connector 114, and a second sealing ring (not shown in the figure) is provided in the second sealing groove 119.

[0038] In order to reduce production costs (threading is required on the inlet shell 110 body 101, which requires the metal shell 101 to have a certain thickness, and the cost of metal is much higher than that of plastic) and improve production efficiency, the valve seat 103 is also provided with a sleeve 120 that matches the shell 101, and the sleeve 120 is provided with connecting threads 121 for installing the valve core.

[0039] To enhance user comfort, the sleeve 120 is also provided with a gap groove 122 to reduce heat transfer.

[0040] In order to strengthen the valve core 102 and facilitate its positioning against the housing 101, the bottom of the water outlet seat 106 is also provided with a third reinforcing rib 123 that abuts against the bottom of the housing 101.

[0041] To facilitate the installation of the inlet housing 110, the inlet groove 109 is matched with the inlet housing 110. The inlet housing 110 is inserted into the housing 101. The valve core 102 is also provided with a third sealing groove 124 that matches the port of the inlet housing 110.

[0042] To further enhance the sealing performance and prevent water leakage, a third sealing ring (not shown in the figure) is provided in the third sealing groove 124.

[0043] To facilitate fixing the water inlet shell 110 to the shell 101, the water inlet shell 110 is welded to the shell 101. Since the fluid does not directly contact the water inlet shell 110, the welding here only serves to fix it. The welding method can be ring welding or spot welding.

[0044] To enhance the functionality of the faucet and enable it to output hot and cold water, there are two water inlet holes 105, and the water inlet seat 107 is configured to match the water inlet holes 105.

[0045] To enhance the functionality of the shower faucet, the water outlet seat 106 can be either a single hole or a through hole. The single hole water outlet seat 106 can be directly connected to the shower head pipe.

[0046] If the water outlet seat 106 is a through hole, the housing 101 will have two water outlet grooves 108 corresponding to the water outlet seat 106, which are used to install a three-in-one shower head pipe. The three-in-one shower head pipe is common knowledge, and its connection with the water outlet seat is also common knowledge, so it will not be described in detail here.

[0047] Working principle: During assembly, first, the valve core body 102 is placed inside the housing 101, and then the water inlet pipe is inserted into the water inlet seat 107. At this time, the water inlet shell 110 can be inserted into the water inlet groove 109. Meanwhile, the connecting seat 114 corresponds to the mounting groove 111. Then, the positioning tube 115 is locked onto the connecting seat 114. Subsequently, the water inlet shell 110 is welded to the housing 101 together using a welding machine to complete the installation of the water inlet shell 110. Finally, the valve core is installed on the valve seat 103 through the valve core cover to complete the assembly.

[0048] In use, fluid flows from the water supply pipe into the positioning pipe 115, then from the positioning pipe 115 to the valve core body 102, and finally into the valve core on the valve seat 103. Under the control of the valve core, it flows to the water outlet 104 and finally flows out from the water outlet seat 106 to complete the water discharge.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions above are only illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
