[0025] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that when a component is said to be "mounted on" another component, it can be directly mounted on the other component or may be interspersed with a component. When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figures 1 to 8 As shown, a faucet of this utility model includes a housing 1 and an inner core 2. The inner core 2 can be installed into the receiving cavity 3 of the housing 1. The inner core 2 is provided with a water flow channel 4. The inner core 2 is provided with a plurality of openings 5, each opening 5 corresponding to the flow channel 4. An end cap 6 is fixedly and sealed at each opening 5 to ensure the airtightness of the flow channel 4.

[0030] Specifically, there are three openings 5 ​​on the inner core 2 at the top and four at the bottom; that is, the end caps 6 in this embodiment also have three at the top and four at the bottom; the number of openings 5 ​​and end caps 6 are set according to product requirements.

[0031] To facilitate positioning and installation, several of the openings 5 ​​are provided with stepped portions 7 (the stepped portions 7 are similar to countersunk holes), which are fitted together with the end caps 6. That is, during installation, several end caps 6 can be placed on the stepped portions 7 first.

[0032] In this embodiment, the end cap 6 is in the shape of a straight line and / or an L-shape, and the shape varies according to the product structure.

[0033] Specifically, the end cap 6 and the inner core 2 can be joined by ultrasonic welding, snap-fit, or plug-in. In this embodiment, the end cap 6 and the inner core 2 are ultrasonically welded together. Ultrasonic welding is a simple process with good sealing performance, eliminating the need for a separate sealing ring and ensuring the product's airtightness.

[0034] Because ultrasonic welding is required, the inner core 2 and the end cap 6 are both integrally injection molded from plastic. The outer shell 1 is also made of plastic.

[0035] For easy fixing, the inner core 2 and the housing 1 are screwed together by a first locking member 8. The position of the first locking member 8 can be on the upper end face, lower end face, or side end face of the inner core 2 and the housing 1. In this embodiment, due to the needs of the product structure, the first locking member 8 is set on the upper end face of the inner core 2 and the housing 1.

[0036] As a specific structural feature, the first locking member 8 has a water supply channel 9 running through its center, facilitating shower water supply.

[0037] Specifically, for secure installation, the housing component 1 is provided with a through hole 10 that mates with the first locking component 8, and the inner core component 2 is provided with a threaded hole 11 that mates with the first locking component 8; after the inner core component 2 and the housing component 1 are installed together, the through hole 10 can be aligned with the threaded hole 11.

[0038] Specifically, the first locking member 8 has an external threaded post 12, which is threadedly connected to the threaded hole 11. The lower end face 18 of the first locking member 8 mates with the end face 13 (counter-recessed) of the outer ring of the through hole 10. That is, during installation, the first locking member 8 passes through the through hole 10 and is threaded into the threaded hole 11, thereby fixing the first locking member 8, the inner core member 2, and the housing member 1. Sealing rings are also provided at both ends of the first locking member 8 to ensure sealing.

[0039] In this embodiment, depending on the needs of the product, a second locking member 16 and a third locking member 17 are also provided. The second locking member 16 and the third locking member 17 have similar structures to the first locking member 8, and will not be described in detail here.

[0040] Specifically, it also includes a first button 14 and a second button 15. The first button 14 controls the direction of water flow (such as shower, shower head, faucet), and the second button 15 controls the water temperature.

[0041] In this embodiment, the inner core 2 is first injection molded, and then several end caps 6 are placed at the opening 5 of the inner core 2 and ultrasonically welded together to prevent water leakage from the opening 5. Then the inner core 2 is installed with the housing 1 and locked and fixed with the first locking member 8, the second locking member 16, and the third locking member 17, thus roughly completing the assembly of the faucet. Other components, such as the first button 14 and the second button 15, are then installed successively.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
