Problems solved by technology
[0005] However, it is difficult for the above-mentioned type of water purifier to guarantee its sealing performance when the water pressure is relatively high, for example, under the pressure of 125PSI (PoundsPer Square Inch, pounds per square inch), and the connection between the rotary joint and the water filter housing will appear. Water leakage, causing safety and health risks, and causing inconvenience to users

Embodiment Construction
[0022] Such as figure 1 A refrigerator equipped with the water filter of the present invention is schematically shown. Figures 2 to 4 The water filter shown in is mainly composed of a filter main body 1, a filter front cover assembly 20, a filter rear cover assembly 30 and a water pipe locking mechanism (see Figure 4 ). The inside of the filter main body 1 accommodates a filter element for absorbing tiny particles in water to achieve the purpose of water purification. An upstream interface 12 and a downstream interface 13 are respectively formed on top ends of the front cover assembly 20 and the rear cover assembly 30 . The water pipe locking mechanism is a quick joint structure, including an upstream locking mechanism and a downstream locking mechanism. The upstream locking mechanism fixedly connects the upstream interface 12 with the drinking water source pipeline, while the downstream locking mechanism fixedly connects the downstream interface 13 with the refrigerator w...

The invention provides a water filter for a refrigerator. The water filter comprises a cylindrical filter main body, a filter front cover component, a filter back cover component and a water pipe locking mechanism, wherein the filter front cover component and the filter back cover component are positioned at the two ends of the filter main body; interfaces are formed on the front cover component and the back cover component respectively; the water pipe locking mechanism comprises a clamping head and a clamping seat; the clamping head has an integrally cylindrical structure; a groove is formedon the outer wall of the clamping head along a circumferential direction; one end of the clamping head is provided with an elastic claw part which projects outwards along a radial direction; the clamping seat has an integrally cylindrical structure; an internal through hole of the clamping seat accommodates the clamping head; a depressed conical port is formed on the inner wall of the clamping seal along the circumferential direction; the elastic claw part is embedded in the depressed conical port; the interfaces on the front cover component and the back cover component have cylindrical structures; and the inner walls of the front cover component and the back cover component are provided with stepped parts for positioning the clamping seat. The water filter can be arranged rapidly in a very simple and convenient mode through a rapid joint interface and sealing is ensured under high pressure.
Description
technical field [0001] The invention relates to a water filter for a refrigerator. Background technique [0002] With the development of refrigerator manufacturing technology, ice making devices or cold drink preparation devices are often installed in existing refrigerators, providing users with more choices and convenience. In order to facilitate operation, a drinking water supply pipe is also configured in the refrigerator to provide drinking water for making ice cubes or cold drinks. Due to pollution of the environment due to wastewater discharge and other reasons, the source of drinking water is also affected. In addition, drinking water will also be polluted twice in the transmission path. Therefore, if drinking water is not purified, it will be used directly for ice making or drinking. , is likely to pose a threat to human health. Thereby, the hygienic problem of refrigerator drinking water is more and more subject to people's attention, and the water filter that is ...
