Technical Field

[0001] The utility model relates to the technical field of sanitary equipment, and particularly relates to an embedded shower head control valve. Background Art

[0002] A shower head control valve is a device for regulating the water output of a shower head, and can control the water temperature of the shower head by controlling the opening degrees of cold water and hot water.

[0003] Most of the existing shower head control valves are embedded in the wall during decoration. After long-term use, the copper shower head control valve is easily corroded and deformed, and at the same time, the risk of water leakage is increased. Moreover, the overall use of copper to prepare the shower head control valve increases the material cost. At present, there are also shower head control valves made of plastic materials. However, since the plastic shaping process requires strict control of temperature changes, and there are other factors affecting plastic molding, the shower head control valve made of plastic materials is prone to deformation during the production process, resulting in a low yield rate of the shower head control valve.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0034] Please refer to Figure 1 and Figure 2 , this embodiment provides an embedded shower faucet control valve 100, which includes a housing 110, a water switching valve body 120, and a body rubber coating 130. The housing 110 is sleeved on the outer surfaces of the body rubber coating 130 and the water switching valve body 120, providing protection and support for the water switching valve body 120 and the body rubber coating 130.

[0035] Please refer to Figure 3, the water switching valve body 120 is a copper body, which includes a valve body assembly 122 and a first water passage 121. The water switching valve body 120 is one of the key structures for connecting the inlet and outlet water pipes and controlling the outlet water temperature.

[0036] The first water passage 121 is used to communicate with the inlet and outlet water pipes. Therefore, the first water passage 121 has at least a water inlet and a water outlet. In this embodiment, there are two water inlets of the first water passage 121, namely a hot water inlet and a cold water inlet, and the connection line of the hot water inlet and the cold water inlet is perpendicular to the axis of the shower head control valve 100; there are also two water outlets of the first water passage 121, and the connection line of the two water outlets is parallel to the axis of the shower head control valve 100. The two water outlets can be respectively used for supplying water to the shower head and supplying water to the water pipe below to meet different water use requirements of users.

[0037] The valve body assembly 122 is installed on the first water passage 121, and it includes a valve core, a valve stem and other components for regulating the opening and closing of the water inlets and outlets of the first water passage 121. The valve core of the valve body assembly 122 is arranged in the first water passage 121, and the installation part 1221 for controlling the opening and closing of the valve core is connected to the valve core. It extends along the first surface direction of the first water passage 121 and protrudes from the first surface.

[0038] Please refer to Figure 4 , the main body rubber coating 130 includes a second water passage 131. The second water passage 131 is sleeved on the surface of the first water passage 121, and a first opening 132 is provided at the position corresponding to the installation part 1221 on the second water passage 131, and the installation part 1221 passes through the first opening 132.

[0039] Please refer to Figures 3 to 5 , a plurality of installation grooves 123 are provided on the surface of the first water passage 121. The main body rubber coating 130 is injection molded on the outer surface of the copper body, and the second water passage 131 and the first water passage 121 are positioned by matching with the installation grooves 123.

[0040] Since the main body rubber coating 130 is injection molded on the surface of the copper body, correspondingly, the main body rubber coating 130 of this embodiment also has two water inlets and two water outlets, and they all correspond to the water inlets and outlets of the copper body one by one.

[0041] Please refer to Figure 2 and Figure 6, in this embodiment, the installation groove 123 is designed on the outer wall surfaces of the water inlet and outlet of the copper body. In addition, the installation groove 123 is also provided on the outer surface of the first water passage 121 corresponding to the installation portion 1221 at one end of the copper body away from the water inlet. By designing multiple installation grooves 123, during the injection molding process of the main body rubber coating 130, the main body rubber coating 130 can be limited by the installation grooves 123 with the copper body, avoiding relative movement between the main body rubber coating 130 and the copper body.

[0042] In other embodiments, the position of the installation groove 123 can also be designed in other areas, or installation grooves 123 can be designed on the entire outer surface of the copper body, as long as it is ensured that the main body rubber coating 130 can be limited by the installation grooves 123 with the copper body, avoiding relative movement between the main body rubber coating 130 and the copper body.

[0043] In this embodiment, the lengths of the inlets and outlets of the second water passage 131 both exceed the lengths of the inlets and outlets corresponding to the first water passage 121, so that the main body rubber coating 130 can integrally wrap the copper body, preventing the copper body from corroding and rusting.

[0044] In this embodiment, the housing 110 includes a main body housing 110 and a valve core housing 111. The main body housing 110 is sleeved on the outer surfaces of the water switching valve main body 120 and the main body rubber coating 130, and a second opening 114 is provided at the position corresponding to the installation portion 1221 on the main body housing 110. The valve core housing 111 is matched with the main body housing 110 through the second opening 114 and is hermetically connected to the installation portion 1221, so that the valve core housing 111 is sleeved on the outer surface of the installation portion 1221.

[0045] In order to facilitate the user to adjust the water outlet temperature, the housing 110 corresponding to the installation portion 1221 needs to be separately provided from the main body housing 110. Therefore, a valve core housing 111 is specifically designed for the installation portion 1221. The valve core housing 111 protrudes from the surface of the main body housing 110. While accommodating the installation portion 1221, the user can directly operate the valve core housing 111 to control the opening and closing of the valve core, realizing the control of the water outlet temperature.

[0046] In this embodiment, in order to prevent the user from taking out the valve core housing 111 when operating the valve core housing 111, positioning protrusions 1141 and positioning grooves 1142 are arranged at intervals on the second opening 114, and a limiting protrusion 1111 is provided on the valve core housing 111. The limiting protrusion 1111 can selectively pass through the positioning groove 1142 and rotate the valve core housing 111 so that the limiting protrusion 1111 contacts the positioning protrusion 1141.

[0047] Due to the design of the positioning protrusion 1141 and the positioning groove 1142, the valve core housing 111 needs to be rotated by a certain angle to be disengaged from the second opening 114, which provides guarantee for the installation and use of the valve core housing 111.

[0048] In this embodiment, after the valve core housing 111 rotates 45°, the limit protrusion 1111 contacts the positioning protrusion 1141.

[0049] In this embodiment, the main body housing 110 is of a split structure. The main body housing 110 includes a first housing 112 and a second housing 113. A groove is provided on the outer surface of the first housing 112, and a protrusion is provided on the inner surface of the second housing 113. The water switching valve main body 120 and the main body rubber coating 130 are accommodated between the first housing 112 and the second housing 113. The first housing 112 and the second housing 113 are fixed by the cooperation of the groove and the protrusion, and the second opening 114 is located on the second housing 113. Therefore, an inverse buckle connection is formed between the first housing 112 and the second housing 113, improving the connection stability between the first housing 112 and the second housing 113.

[0050] In other embodiments, the main body housing 110 can also be of an integrally formed structure. After the main body rubber coating 130 is injection molded on the surface of the copper main body, the main body rubber coating 130 and the copper main body can be integrally placed in a mold to form the integrally formed main body housing 110. In this embodiment, in order to simplify the production process of the main body housing 110 and for the convenience of installing the first housing 112 and the second housing 113, the main body housing 110 adopts a split structure.

[0051] In this embodiment, the main body rubber coating 130 is a PPR rubber coating. The connection between the main body rubber coating 130 and the water inlet pipe or the water outlet pipe can adopt hot melt connection, which is more tightly connected and convenient for connection.

[0052] A pre-embedded shower faucet control valve 100 provided by an embodiment of the present utility model has the following installation process:

[0053] First, a copper main body is cast, and then the copper main body is placed in a mold, and PPR melt is injected into the mold to form the main body rubber coating 130 on the surface of the copper main body. The main body rubber coating 130 has a first opening 132 for accommodating the installation part 1221. Then, the main body rubber coating 130 and the copper main body are together placed into the first housing 112 and the second housing 113. The installation part 1221 protrudes from the second opening 114 of the second housing 113. The first housing 112 and the second housing 113 are inversely buckled and connected. The limit protrusion 1111 on the valve core housing 111 passes through the positioning groove 1142 on the second opening 114, and then rotates 45° so that the limit protrusion 1111 contacts and limits with the positioning protrusion 1141 on the second opening 114. Then, the valve core housing 111 is continuously rotated to make the valve core housing 111 be hermetically connected with the installation part 1221.

[0054] During installation, the shower head control valve 100 is embedded in the wall, the main body housing 110 is completely buried in the wall, and the valve core housing 111 protrudes from the wall surface to facilitate the user to adjust the water outlet temperature. In this structure, since a layer of main body rubber coating 130 is injection-molded on the surface of the copper main body, it can prevent the copper main body from being corroded after being buried in the wall for a long time, and avoid the corrosion and deformation of the shower head control valve 100, resulting in water leakage. In addition, since there is a copper main body to support inside the main body rubber coating 130, the injection-molded main body rubber coating 130 will not deform either, and the qualified rate is improved. Moreover, since the main body rubber coating 130 outside the copper main body has a certain plasticity, it has good installability, while the copper main body inside the main body rubber coating 130 has a certain strength, making the whole formed by the injection molding of the two have both good strength and characteristics convenient for installation. Through the cooperation of the copper main body and the main body rubber coating 130, the production cost of the shower head control valve 100 can also be reduced.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
