Problems solved by technology

When the top surface of the closed filter gall or filter cartridge cover is only provided with a convex or concave limiting structure and a cavity cover, this mode is more suitable, but for the limit structure and the cavity that are set on the top surface of the closed filter gall or filter cartridge cover If there is an object between the covers so that there is a large space between the cavity cover and the top surface of the closed filter gall, or there is a display device such as a display screen inside the cavity cover, it is difficult to adopt a filter lock with a concave or convex structure in the axial direction of the machine base. technology program
The above-mentioned defects and deficiencies cause the water purifier to have serious hidden dangers

Embodiment 1

[0023] Example 1. In the accompanying drawings, the lower part of the closed filter gall and the cavity of the machine base are screwed together to form an integral body through a threaded joint structure, that is, the inner side of the closed filter gall and the cavity of the machine base where the closed filter gall is placed are respectively provided with thread structures corresponding to the threaded joints, The closed filter gall is axially screwed into the cavity of the machine base through the thread structure and is plugged with the water outlet provided on the bottom surface of the cavity of the machine base. The water outlet on the bottom surface of the base cavity forms a water passage for sealing the filter gall. The closed filter gall located at the high position of the screw connection moves downward by itself during the rotation along the screw connection structure, and the external water port is sealed and plugged with the water outlet pipe wall of the machine...

Embodiment 2

[0029] Example 2. On the basis of Embodiment 1, the threaded connection structure used for the screwed connection between the housing cavity and the lower part of the closed filter gall is changed to a screwed connection structure. The cavity of the machine base and the lower part of the closed filter gallbladder are connected by a screw clamp structure in which the concave tooth buckle and the convex tooth buckle are axially inserted and screwed together. The structure and function of the axial insertion gap 2 arranged on the upper end surface of the closed filter gall remain unchanged.

[0030] Similarly, the cavity of the machine base and the lower part of the closed filter gall can also be connected by a screw clamp connection structure in which the convex tooth buckle and the concave tooth buckle are axially inserted and screwed together.

[0031] The gallbladder filter device involved in Embodiments 1 and 2 includes two housings 1 that are respectively provided with a s...

Embodiment 3

[0032] Example 3. Machine filter gallbladder adopts open filter gallbladder. The bottom surface of the filter cartridge cavity is provided with a water outlet; the built-in filter gall is placed in a closed cavity formed by a screw connection between the upper part of the filter cartridge cavity and the chamber cover, and is sealed and matched with the corresponding water outlet of the filter cartridge cavity. Both sides of the filter material layer are respectively connected to the corresponding water outlets of the filter cartridge cavity to form a water passage; the screw connection structure is either an axial screw connection structure through a thread structure, or an axial mutual insertion through concave and convex tooth buckles. The screw connection structure is screwed together; the cavity cover at the high position of the screw connection moves downward by itself during rotation along the screw connection structure, limiting the axial movement of the built-in filter...

Abstract

The invention relates to water treatment industry, concretely relates to drinking water filtration, and discloses a filter liner rotation-connection interlocking method for a multiple-filter-liner water purifier and a filter liner device. Filter liners cooperate with a water purifier base cavity body through a rotation-connection structure or cavity covers cooperate with filter cylinder cavity bodies through a rotation-connection structure; a shell body of each seal filter liner is provided with an axial-direction insertion-connection gap, and is also provided with an axial-direction insertion piece which is in insertion-connection cooperation with the corresponding axial-direction insertion-connection gap; and when the seal filter liners are in rotation-connection cooperation with the water purifier base cavity body at a rotation-connection lower place, the axial-direction insertion-connection gaps in the shell bodies of the two seal filter liners are corresponding with each other, and two plugs which are arranged at the axial-direction insertion pieces are separately inserted into the axial-direction insertion-connection gaps of the shell bodies of the two seal filter liners to limit rotation of the seal filter liners. Each cavity cover is provided with an axial-direction insertion-connection gap, and is also provided with an axial-direction insertion piece which is in insertion-connection cooperation with the corresponding axial-direction insertion-connection gap; and when the cavity covers are in rotation-connection cooperation with the filter cylinder cavity bodies at a rotation-connection lower place, the axial-direction insertion-connection gaps of the two cavity covers are corresponding with each other, and two plugs which are arranged at the axial-direction insertion pieces of the cavity covers are separately inserted into the axial-direction insertion-connection gaps of the two cavity covers to limit rotation of the cavity covers.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] The use of the rotary plug connection mode avoids the difficulties in plugging and unplugging in the existing in-line connection mode, the difficulty of inserting the filter liner into place, the easy damage of the filter liner's protruding insertion nozzle seal, and the difficulty in taking out the built-in liner liner. The connection or separation between the filter device and the machine is simple, fast and labor-saving. Users can replace the filter tube by themselves, avoiding the inconvenience and service expenses caused by professional on-site service, and correspondingly reducing the use cost of the filter tube. Convenient for remote users. When the filter gall with the screw connection structure is connected and matched with the cylinder or cavity in the water passage of the ma...
