Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a shower faucet. Background Art

[0002] In everyday life, shower faucets are often mounted directly on the wall. These faucet bodies are typically manufactured in one piece using a casting process. During casting, the faucet body incorporates both the water channel and the connector for connecting to the water inlet pipe. However, these integrally cast faucets require multiple, complex machining steps after the casting process. Furthermore, these integrally cast faucet bodies are long and bulky, resulting in high production costs.

[0003] In existing faucet structures with a metal outer shell and a plastic inner shell, the valve core is typically secured by an end cap, which is typically screwed onto the opening of the metal shell corresponding to the valve core to axially secure the valve core. However, this method also requires machining a threaded connection port on the metal shell corresponding to the valve core, which also inevitably requires multiple machining steps on the metal shell, resulting in high production costs.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the present invention.

[0028] Example

[0029] Combine Figures 1 to 8 As shown, this embodiment provides a shower faucet, including a faucet body, the faucet body including a plastic inner shell 2 having a water flow channel and a hollow metal outer shell 1 covering the plastic inner shell 2; at least one end of the plastic inner shell 2 is provided with a valve core cavity; a plurality of connecting members are evenly distributed around the periphery of the valve core cavity, and an end cap 24 is provided at the opening of the valve core cavity; the end cap 24 is connected to the connecting member by a plurality of locking members to fix the valve core in the valve core cavity.

[0030] The faucet body is configured as a plastic inner shell 2 with a water flow channel and a hollow metal outer shell 1 covering the outside of the plastic inner shell 2; the metal outer shell 1 has no other structure, the structure is simple and easy to form, can better ensure its appearance, and is light in weight and low in cost; and a plurality of connecting parts are evenly distributed on the periphery of the valve core cavity, and the end cover 24 is connected to the connecting parts by a locking part to fix the valve core in the valve core cavity. This method does not require any structural features to be designed on the metal shell, which not only ensures the strength of the connection of the end cover 24, but also realizes the balanced fixation of the end cover 24 to the valve core.

[0031] In this embodiment, the metal shell 1 is a stainless steel, tubular structure with a central opening. It can be a square tube or a round tube, and can be directly formed from a tubular profile. Specifically, in this embodiment, the square metal shell 1 is used as an example. Two first openings 4 are provided on the rear side for connection to the water inlet on the wall via the connecting assembly 3. Second openings 23 are provided on the upper and lower sides for the outlet pipe to pass through and connect to the water outlet 14 of the plastic inner shell 2. The metal shell 1 only needs to be machined with openings at appropriate locations. It has no other internal structures. The simple structure facilitates molding, can better maintain its appearance, and is lightweight and low-cost.

[0032] In this embodiment, the two ends of the plastic inner shell 2 are respectively provided with a first valve core cavity 11 and a second valve core cavity 12; the plastic inner shell 2 is provided with two water inlets 13 and two water outlets 14. Figures 6 to 8 As shown, the valve core cavity is provided with a side opening for receiving the nut 17 in a slot 25. Above the slot 25 is a through-hole 15 for the bolt 16 to pass through. The end cap 24 is provided with a stepped hole 26 corresponding to the through-hole 15, which is fixedly connected to the nut 17 via the bolt 16. The connection via the standard bolt 16 ensures a tight seal between the valve core and the bottom end face of the valve core cavity, while also ensuring pressure-bearing strength. Of course, in other embodiments, the nut 17 can also be integrally embedded in the plastic inner housing 2, but this is not discussed in detail here.

[0033] In this embodiment, a thermostatic valve core assembly 18 and a switching valve core assembly 19 are installed in the first valve core chamber 11 and the second valve core chamber 12, respectively. The plastic inner shell 2 is provided with two water inlet channels 21, a water flow channel 22, and two independent water outlet channels 20. The two water inlet channels 21 respectively connect the water inlet 13 and the two valve core water inlets 13 of the thermostatic valve core assembly 18; the water flow channel 22 connects the mixing chamber of the thermostatic valve core assembly 18 and the valve core water inlet 13 of the switching valve core assembly 19; and the two water outlet channels 20 independently connect the water outlet 14 and the valve core water outlet hole of the switching valve core assembly 19. The two water inlet channels 21 are used to respectively admit cold water and hot water into the thermostatic valve core assembly 18 for mixing and temperature control. The mixed water then flows through the water flow channel 22 into the switching valve core assembly 19, where it switches between different water outlet channels 20 to form water. The provision of the two independent water outlet channels 20 increases the water flow area, which greatly increases the water flow rate compared to products of the same size.

[0034] In other embodiments, a first plug and at least one second plug may also be included; a temperature regulating valve core assembly 18 is installed in the first valve core cavity 11; the first plug is used to block the second valve core cavity 12; the second plug is used to block one or more of the water outlets 14. The plastic inner shell 2 can be shared. For example, when it is necessary to realize two functional water outlets, it is necessary to install a switching valve core assembly 19 in the second valve core cavity 12, and switch different water outlet channels 20 through the switching valve core assembly 19 to discharge water. When only one functional water outlet is required, it is necessary to use the first plug to block the second valve core cavity 12, and use the second plug to block the water outlet 14 of the other water outlet channels 20 that do not discharge water. This method realizes the sharing of the plastic inner shell 2, and only requires the selection of the suitable metal outer shell 1, without the need to open a new mold to realize a single water outlet function.
