Description

Technical Field

[0001] The utility model relates to the technical field of showers, in particular to a shower with a filtering device. Background Art

[0002] There are many shower units on the market now, whose valve core and water channel body are wrapped in a decorative shell, and the decorative shell has a platform for placing items. In existing shower units, the valve core (especially the thermostatic valve core) will add a layer of filter net outside the valve core for the stability of the product function. After the product has been used for a long time, some impurities will be attached to the filter net, resulting in poor filtering effect and affecting the flow rate, so the valve core needs to be disassembled and cleaned regularly. In order to avoid the trouble and poor user experience caused by disassembling and cleaning the valve core, subsequent products have improved the filter net to the position of the water inlet. Although it can improve and reduce the difficulty of disassembling the filter net, there are still complex operations such as turning off the water source and disassembling the shower rod, and then installing it back. The efficiency of disassembling and replacing the filter net is relatively low. Utility Model Content

[0027] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0028] refer to Figures 1 to 5 As shown, the utility model discloses a shower with a filtering device, comprising a water channel body 2 arranged in a shower housing 1, a sealing member 3, a spring 4 and a filtering device 5;

[0029] A water passage cavity 21 is provided in the water channel body 2; a first end of the water passage cavity 21 passes through a through hole 11 provided on the surface of the shower housing 1, and a water inlet 211 and a water outlet 212 are provided in the axial direction of the inner wall of the water passage cavity 21, the water inlet 211 is connected to the water source of the shower, and the water outlet 212 is connected to the water outlet end of the shower, so as to supply water to water outlet devices such as overhead spray and shower head;

[0030] The sealing member 3 is movably fitted in the water passage chamber 21 along the axial direction of the water passage chamber 21, and is movably blocked between the water inlet 211 and the water outlet 212 under the elastic force of the spring 4. The spring 4 is arranged between the sealing member 3 and the second end of the water passage chamber 21.

[0031] The filter device 5 is movably disposed in the through hole 11 and is threadedly connected to the inner wall of the water passage chamber 21;

[0032] When the filter device 5 is installed in place, it abuts against and pushes the seal 3 to compress the spring 4 and connect the water inlet 211 with the water outlet 212. Water enters the water chamber 21 and the filter device 5 in turn from the water inlet 211 and flows out of the water outlet 212 after being filtered by the filter device 5.

[0033] Through the above scheme, the utility model provides elastic force by setting the spring 4 so that the seal 3 automatically blocks the connection between the water inlet 211 and the water outlet 212 when the filter device 5 is removed, so that the shower will not leak after the user removes the filter device 5, and there is no need to shut off the water source of the shower. In addition, the filter device 5 can be directly disassembled and assembled on the surface of the shower housing 1 by means of threaded connection, and the operation is very convenient and efficient.

[0034] Specific embodiments of the present utility model are shown below.

[0035] The second end of the water passage chamber 21 is installed with a plug 6 by means of threaded connection, and the two ends of the spring 4 respectively abut against the seal 3 and the plug 6. The plug 6 can adjust the installation position in the axial direction of the water passage chamber 21 by means of threaded connection, so as to adjust the compression amount of the spring 4 in the installed state.

[0036] Furthermore, the end surface of the seal 3 facing the plug 6 is recessed to form a movable groove 31, and the spring 4 is arranged in the movable groove 31. The movable groove 31 can be used to install the spring 4 and guide the expansion and contraction direction of the spring 4 to ensure the functional stability of the spring 4.

[0037] At the same time, the inner wall of the waterway body 2 is provided with an internal thread 214, and the peripheral surface of the filter device 5 is provided with an external thread 55 matching the internal thread 214, so as to realize the threaded connection between the filter device 5 and the waterway body 2; and the inner diameter of the internal thread 214 is smaller than the outer diameter of the seal 3, so that the seal 3 finally abuts against the side of the internal thread 214 close to the water inlet 212 under the elastic force of the spring 4, and will not be pushed out of the first end of the water cavity 21 (i.e., limiting the movable stroke of the seal 3), and the seal 3 under this structure can be disassembled and assembled by disassembling the plug 6, and the plug 6 plays the role of limiting the seal 3 from falling out of the second end of the water cavity 21. Of course, an additional structure can also be provided to limit the movable stroke of the seal 3.

[0038] A sealing bevel 213 is provided on one side of the water inlet 211 near the water outlet 212, and a sealing ring 7 is provided on the circumferential surface of the sealing member 3. The sealing ring 7 is movably matched with the sealing bevel 213 as the sealing member 3 moves axially in the water passage chamber 21, so that the water flowing out of the water inlet 211 cannot pass through the position where the sealing bevel 213 is located, and thus cannot flow into the water outlet 212. Of course, the sealing ring 7 can also be integrally formed on the circumferential surface of the sealing member 3 as a part of the sealing member 3, that is, the sealing member 3 with the sealing ring 7 on the circumferential surface can be directly formed using materials such as rubber.

[0039] The filter device 5 is provided with a plurality of bosses 51 on the end face facing the seal 3, and the filter device 5 is a hollow structure provided with a water outlet 52 and a filter screen 53 built in. The bosses 51 abut against the end face of the seal 3, and water can enter the filter device 5 through the gaps between the bosses 51, and after being filtered by the filter screen 53, flow from the water outlet 52 to the water outlet 212.

[0040] The end surface of the filter device 5 facing away from the seal 3 is recessed to form a hexagonal hole 54, which is convenient for using a hexagonal wrench to disassemble and assemble the filter device 5.

[0041] Generally speaking, two water inlet channels are arranged in the water channel body 2 of the shower, corresponding to the cold water inlet and the hot water inlet, so the accessories such as the sealing member 3, the spring 4 and the filtering device 5 in the utility model are arranged in two groups.

[0042] refer to Figures 3 to 5 As shown, the working principle of the utility model is:

[0043] When the filter device 5 is installed in place, the seal 3 is pushed by the water filter 5 and causes the sealing ring 7 to leave the sealing slope 213, and the water path is connected; when the filter device 5 is gradually removed, the seal 3 moves toward the first end of the water chamber 21 under the action of the spring 4, and finally causes the sealing ring 7 to abut against the sealing slope 213, and the water path is blocked.

[0044] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
