Description

Technical Field

[0001] This utility model belongs to the technical field of bathroom equipment, and specifically refers to a shower arm structure. Background Technology

[0002] Currently, in addition to shower rods, overhead shower heads can also be connected to the water outlet on the wall via the shower arm, which has the advantage of simple structure.

[0003] To improve showering performance, many handheld showerheads with built-in filters have appeared on the market, while overhead showerheads with filters are relatively rare. This is because overhead showerheads are generally installed at a higher position, making it difficult to replace the filter cartridge after installation. To address this, some manufacturers have researched external filter designs. Water entering the shower arm is first guided through a water pipe into the external filter cartridge for filtration, and then the filtered water is returned to the shower arm's water path. However, this external filter design requires an additional housing and structure to secure the filter cartridge, and it also extends the length of the water path. Insufficient water pressure can further reduce the flow rate, affecting the water output. Furthermore, external filters can detract from the product's aesthetic appeal, potentially reducing the purchasing desire of some customers. Utility Model Content

Detailed Implementation

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] refer to Figures 1 to 4 As shown, this utility model discloses a shower arm structure, including a shower arm body 1, a filter element 2, and a sealing cover 3; The shower arm body 1 has a mounting cavity 11 near the lower end on the front side, and a water inlet hole 12 communicating with the shaft end of the mounting cavity 11 on its back side. Filter element 2 is installed inside mounting cavity 11; The sealing cap 3 is detachably connected to the opening of the mounting cavity 11 and fixes the filter element 2; Water enters the filter element 2 through the water inlet hole 12, is filtered, and then flows out, being transported outward through the water passage of the shower arm body 1.

[0023] Through the above solution, this utility model directly installs the filter element 2 inside the shower arm body 1 by opening an installation cavity 11 on the front side of the shower arm body 1. There is no need to use additional parts to accommodate the filter element 2, nor is there an additional water pipe to connect the water circuit. Furthermore, by directly connecting the filter element 2 to the water inlet end of the shower arm body 1, the filtered impurities can be isolated at the source, preventing impurities from accumulating in the water circuit of the shower arm body 1. At the same time, the installation cavity 11 is located near the lower end, which is closer to the user and makes it convenient to replace the filter element 2.

[0024] The following are specific embodiments of the present invention.

[0025] The mounting cavity 11 is provided with a water distribution cavity 13 on its side, and the side wall of the mounting cavity 11 is provided with a first water channel 14 that connects to the water distribution cavity 13. The water distribution cavity 13 is used to install the switching valve 4 of the shower arm, and is provided with a first water outlet 15 and a second water outlet 16 that are adjusted by the switching valve 4. The switching valve 4 can adjust the opening degree of the first water outlet 15 and the second water outlet 16 respectively to achieve opening and closing. The first water outlet 15 is used to connect to the hand shower. The second water outlet 16 extends into a second water channel 17, which bypasses the side of the mounting cavity 11 and extends upward to the upper end of the shower arm body 1, and is used to connect to the overhead shower.

[0026] The sealing cover 3 and the opening of the mounting cavity 11 are detachably connected by a rotating snap-fit ​​mechanism. Specifically, the inner wall of the opening of the mounting cavity 11 is provided with a rotating groove 111, and the circumferential surface of the sealing cover 3 is provided with a locking block 31 that movably engages within the rotating groove 111, making assembly easier and more efficient.

[0027] A first sealing ring 5 is provided between the filter element 2 and the side wall of the mounting cavity 11 near the water inlet 12, and a plurality of water passage holes 21 are provided on the end face of the filter element 2 at this end. Filter material 22 is provided inside the filter element 2. A second sealing ring 6 is provided between the sealing cover 3 and the inner wall of the opening of the mounting cavity 11, thereby improving the sealing and leak-proof performance. The former ensures that the water flow from the water inlet 12 can only enter the filter element 2 from the end face of the filter element 2, ensuring that the water flow can be filtered by the filter material 22. The latter prevents water leakage at the location of the sealing cover 3. In this embodiment, water passage holes 21 and a first sealing ring 5 are provided on both circumferential surfaces of the filter element 2, so the installation direction is not limited, and it is not necessary to deliberately adjust the orientation of the filter element 2 when installing it.

[0028] This utility model also includes a magnetic shower head holder 7 installed at the lower end of the shower arm body 1. The magnetic shower head holder 7 has a built-in magnet 71, which can magnetically fix the handheld shower head.

[0029] Furthermore, the aforementioned magnetic shower head 7 is provided with a ball head 72 that rotates and engages with the lower end of the shower arm body 1, allowing the angle of the magnetic shower head 7 to be adjusted for more flexible use.

[0030] Secondly, the lower front of the shower arm body 1 is provided with a movable groove 18 for the ball head 72 to rotate and engage. A first washer 8 is provided in the movable groove 18. A screw cap 9 is threadedly connected to the outer wall of the movable groove 18. A second washer 10 is provided in the screw cap 9. The ball head 72 passes through the screw cap 9 and the second washer 10, with the first washer 9 and the second washer 10 respectively clamped on both sides of the ball head 72. Thus, relying on the elasticity of the first washer 8 and the second washer 10, when the screw cap 9 is tightened, the first washer 8 and the second washer 10 will be clamped and the pressure will be transferred to the surface of the ball head 72, thereby providing sufficient friction to prevent the ball head 72 from rotating, making it difficult for the ball head 72 to rotate, thus fixing the magnetic shower seat 7 as a whole. When the screw cap 9 is loosened, the ball head 72 is no longer restricted from rotating, making it easier for the ball head 72 to rotate, and the angle of the magnetic shower seat 7 can be adjusted. Among them, the opposing surfaces of the first washer 8 and the second washer 10 can be set as arc surfaces to achieve spherical fit with the ball head 72, and the two washers can fit more tightly on the surface of the ball head 72.

[0031] In addition, the first washer 8 is made of rubber, and the second washer 10 is a C-shaped part, which is easy to deform and pass through by the ball head 72.

[0032] A water inlet connector 20 is installed at the relative position of the shower arm body 1 and the water inlet hole 12. This connector is used to connect to the water outlet connector on the wall and can fix the shower arm to the wall.

[0033] In this embodiment, the shower arm body 1 is a split design with a front cover and a rear shell, which facilitates the formation of the internal water channels.

[0034] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
