Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a water purifier filter cartridge leak prevention device. Background Technology

[0002] A water purifier, also called a water filter machine or water purifier, is a water treatment device that performs deep filtration and purification of water according to the requirements of water use. Common types include microfiltration water purifiers, high-efficiency ultrafiltration water purifiers, RO reverse osmosis water purifiers, activated carbon filter water purifiers, and faucet-type water purifiers. Among them, RO reverse osmosis water purifiers have the highest filtration accuracy, reaching 0.0001 microns, and can remove almost all impurities in the water, including bacteria, viruses, heavy metal ions, etc.; high-efficiency ultrafiltration water purifiers have a filtration accuracy of about 0.01 microns, and can effectively remove harmful impurities such as sediment, rust, and bacteria, while retaining beneficial minerals; activated carbon filter water purifiers mainly use activated carbon to adsorb organic matter, residual chlorine, and odors in the water.

[0003] The following problems exist: With the increasing severity of water pollution, it has become increasingly difficult to access healthy and pure drinking water. As a result, water purifiers, as an important health product to ensure drinking water safety, have been warmly welcomed and highly favored by consumers. However, in the long-term use of ordinary water purifiers, the water purification effect of the filter cartridges will gradually decrease, and the filtration rate will also decrease significantly. When the filter cartridges need to be replaced, due to their complex internal structure, not only will it take a lot of time to disassemble and install, but leaks are also prone to occur during the replacement process, causing inconvenience and trouble for users. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A water purifier filter cartridge leak-proof device includes a housing. U-shaped bases are fixedly connected to the bottom ends of the outer walls on both sides of the housing. U-shaped placement frames extend through both sides of the front end of the housing. Limiting plates are fixedly connected to the bottom ends of the inner walls of the U-shaped placement frames. Filter cartridge bodies are sleeved on the top ends of the inner walls of the U-shaped placement frames. Insert rings are fixedly connected to both sides of the front end of the filter cartridge bodies. Threaded rods are fixedly connected to both sides of the front end of the U-shaped placement frames. A baffle is sleeved on one end of the outer wall of each threaded rod, and a nut is threaded onto the other end of the outer wall of each threaded rod. Insert rods are fixedly connected to both sides of the rear end of each baffle. One end of the outer wall of each insert rod engages with the inner wall of the insert ring. A drain pipe extends through one end of the top of each filter cartridge body, and a water inlet pipe extends through the other end of the top of each filter cartridge body.

[0007] As a further description of the above technical solution: A column is fixedly connected to the top center of the box, and a manifold is fixedly connected to the top of the column. A manifold pipe passes through the front end of the manifold.

[0008] As a further description of the above technical solution: The inner wall of the manifold is fixedly connected to an inner ring at the bottom, and a partition is fixedly connected to the top of the inner ring. Both ends of the partition are provided with a first through hole running vertically through the manifold.

[0009] As a further description of the above technical solution: The inner wall of the inner ring is rotatably connected to a sealing disc, and one end of the sealing disc is provided with a second leakage hole that runs vertically through it.

[0010] As a further description of the above technical solution: Both the baffle and the manifold have a rotating ring running through their top center. The inner wall of the rotating ring is rotatably connected to a rotating rod. The top of the rotating rod is fixedly connected to a rotating plate, and the bottom of the rotating rod is fixedly connected to the top center of the sealing plate.

[0011] As a further description of the above technical solution: The manifold has round holes at both ends of its bottom. A support ring is fixedly connected to the top of the inner wall of each round hole. A slip ring is fixedly connected to the inner wall of each support ring. A spring rod is fixedly connected to both ends of the bottom of each support ring. A return spring is sleeved on the top of the outer wall of each spring rod.

[0012] As a further description of the above technical solution: Each of the inner walls of the circular holes is slidably connected to a collar, and each collar is fixedly connected to a rubber ring. The inner walls of the rubber rings are sleeved with the top of the outer wall of the water inlet pipe. Each collar has a sliding hole at both ends of its top, and the inner walls of the sliding holes are slidably connected to the bottom of the outer wall of the spring rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) When the filter body needs to be replaced, first rotate the sealing plate to move the second leak hole from below the first leak hole of the group to below the first leak hole of another group. During the rotation of the sealing plate, the water entering the manifold from the manifold pipe will accumulate briefly. When the second leak hole moves to below the first leak hole of another group, the water will pass through the first leak hole, the second leak hole, the slip ring and the inlet pipe in sequence into the filter body of another group. Then remove the front baffle of the filter body to be replaced, and lift the collar upward to let the rubber ring get off the inlet pipe. At this time, the filter body can be disassembled and replaced. The whole process not only avoids water leakage, but also brings a lot of convenience to the user.

[0014] (2) By setting the connection structure between the plug rod and the plug ring, the filter body placed in the U-shaped placement frame can be fixed. By setting the rotating plate and the rotating rod, it is convenient for the user to rotate the sealing plate. During the rotation of the sealing plate, the second leakage hole can move directly below the first leakage hole. By setting the reset spring, the collar can be pushed downward, so that the rubber ring is placed on the outer wall of the water inlet pipe, which can achieve a good leak-proof effect.
