Description
Technical Field
[0001] This utility model relates to the technical field of water filters, and in particular to an easily detachable water filter. Background Technology
[0002] Previous water filters mainly consisted of a main body, a cover, and a filter element. The cover and the main body were detachably connected, and the filter element was located inside the main body. The filter element filtered the water. The above-mentioned water filters had the following shortcomings: it was difficult to disassemble the cover and the main body, and it was difficult to replace the filter element. Tools were needed to open the cover, so replacing the filter element and filter screen was very troublesome and difficult. Utility Model Content
[0003] The purpose of this invention is to provide an easy-to-disassemble water filter with an easy-to-replace filter element.
[0004] The purpose of this utility model is achieved as follows:
[0005] A disassembleable water filter includes a main body, a cover, a filter element, and a filter screen. The main body has an inlet and an outlet, and its lower part is open. The filter element is installed inside the inner cavity of the main body, and the filter screen is fitted onto the side wall of the filter element. The cover is threadedly connected to the bottom of the main body, pressing the filter element tightly into the inner cavity of the main body. The upper end of the filter element abuts against the side wall of the inner cavity of the main body. A first sealing ring is provided between the upper side wall of the filter element and the side wall of the inner cavity of the main body, and a second sealing ring is provided at the connection between the cover and the main body. A water passage is provided on the side wall of the filter element, and the upper end of the filter element is open. The inlet, the inner cavity of the cover, the filter element, the inner cavity of the main body, and the outlet are sequentially connected. The main body and cover of this invention are connected by threads, making disassembly and assembly very convenient, thus making filter element and filter screen replacement very easy and convenient.
[0006] The present invention can be further improved in the following ways.
[0007] The inner cavity of the cover is equipped with a water inlet channel, which connects the water inlet and the inner cavity of the cover. Therefore, water first enters the inner cavity of the cover, then passes through the filter element, and then enters the inner cavity of the main body.
[0008] The filter element has a step at the bottom, and the bottom of the filter screen sits on the step, making it very easy and convenient to install and remove the filter screen.
[0009] The filter screen is either a sponge filter screen or a stainless steel filter screen.
[0010] The inlet is equipped with an inlet connection nut, and the outlet is equipped with an outlet connection nut. The inlet and outlet connection nuts facilitate the connection of water lines.
[0011] The bottom of the inner cavity of the cover is provided with a pressing conical groove, and the bottom outer wall of the filter element is provided with a pressure-receiving conical surface. The lower end of the filter element is located in the pressing conical groove. The pressure-receiving conical surface abuts against the inner side wall of the pressing conical groove. This utility model uses the pressing conical groove to press the filter element upward. As long as the cover is loosened, the filter element will fall out of the main body, making disassembly and assembly very easy and convenient.
[0012] The beneficial effects of this utility model are as follows:
[0013] The main body and cover of this utility model are connected by threads, making disassembly and assembly very convenient. Therefore, the replacement of filter elements and filter screens is very convenient and easy. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Example 1, as Figures 1 to 5 As shown, an easily detachable water filter includes a main body 1, a cover 2, a filter element 3, and a filter screen 4. The main body 1 is provided with an inlet 12 and an outlet 11. The lower part of the main body 1 is open. The filter element 3 is installed in the inner cavity of the main body 1. The filter screen 4 is sleeved on the side wall of the filter element 3. The cover 2 is threaded to the bottom of the main body 1. The cover 2 presses the filter element 3 tightly in the inner cavity of the main body 1. The upper end of the filter element 3 abuts against the side wall of the inner cavity of the main body 1. A first sealing ring 5 is provided between the upper side wall of the filter element 3 and the side wall of the inner cavity of the main body 1. A second sealing ring 6 is provided at the connection between the cover 2 and the main body 1. A water inlet 9 is provided on the side wall of the filter element 3. The upper end of the filter element 3 is open. The inlet 12, the inner cavity of the cover 2, the filter element 3, the inner cavity of the main body 1, and the outlet 11 are connected in sequence.
[0021] This is a more specific technical solution of the present invention.
[0022] The inner cavity of the cover 2 is provided with a water inlet 10 corresponding to the water inlet 12, and the water inlet 10 connects the water inlet 12 and the inner cavity of the cover 2.
[0023] Filter 4 is either a sponge filter or a stainless steel filter.
[0024] A water inlet connecting nut 8 is provided at the water inlet 12, and a water outlet connecting nut 7 is provided at the water outlet 11.
[0025] The bottom of the inner cavity of the cover 2 is provided with a pressing conical groove 21, and the bottom outer wall of the filter element 3 is provided with a pressure-receiving conical surface 32. The lower end of the filter element 3 is located in the pressing conical groove 21, and the pressure-receiving conical surface 32 abuts against the inner wall of the pressing conical groove.
[0026] The working principle of this utility model is as follows:
[0027] When this utility model is in operation, water enters the water channel from the inlet 12, then enters the inner cavity of the cover 2, is filtered by the filter screen 4 and enters the filter element 3, then enters the inner cavity of the main body 1, and finally is discharged from the outlet 11.
