Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a water purifier with an easy-to-replace filter screen. Background Technology

[0002] A water purifier, also known as a water filter or water treatment device, is a water treatment device specifically designed for deep filtration and purification of water. Its main function is to remove impurities, pollutants, and harmful substances from water to ensure that the water quality meets safe drinking standards. Water purifiers are widely used in homes, schools, hospitals, and commercial establishments. Small purifiers for home use are the most common type. They can effectively filter out rust, sand, colloids, residual chlorine, odors, discoloration, pesticides, and other chemical agents, as well as impurities such as bacteria, germs, toxins, and heavy metals. Water purifiers often use filter screens to filter impurities in the water. To ensure the purification effect, the filter screen needs to be cleaned frequently or replaced when it is damaged. This requires removing the filter screen cover. However, currently used water purifiers typically have the filter screen fixed to the water inlet of the device with screws, but this type of added filter screen is inconvenient to remove and replace, making disassembly quite troublesome.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4 As shown, a water purifier with easy filter replacement includes a water purifier body 1 and a filter screen 301. One end of the water purifier body 1 is fixedly connected to an inlet pipe 3, and an external water pipe 4 is threaded onto the outer surface of the inlet pipe 3. The other end of the water purifier body 1 is fixedly connected to an outlet pipe 2. The inlet pipe 3 is provided with a disassembly structure 5, which includes a rotating block 501, a rotating rod 502, a first bearing 503, a first bevel gear 504, a rectangular groove 505, a second bevel gear 506, a connecting rod 507, a second bearing 508, a threaded rod 509, a first groove 510, a rectangular slide 511, a rectangular slider 512, a rectangular locking block 513, a first slide 514, a rectangular locking groove 515, and a rectangular rod 516.

[0021] A first groove 514 is formed on both the upper and lower surfaces of one end of the water inlet pipe 3. A rectangular rod 516 is slidably installed in the first groove 514. A filter screen 301 is fixedly installed on one end of the rectangular rod 516. A rectangular groove 505 is formed in the middle of the inside of the rectangular rod 516. A first bearing 503 is fixedly installed in the middle of one end of the rectangular groove 505. A first bearing 503 is fixedly installed on the outer surface of the rotating rod 502 near the other end. The rotating rod 502 passes through the filter screen 301. A first bevel gear 504 is fixedly installed on the other end of the rotating rod 502. A rotating block 501 is fixedly installed on one end of the rotating rod 502. A second bearing 508 is fixedly installed in the middle of both the upper and lower surfaces of the rectangular groove 505. A second bearing 508 is fixedly installed on the outer surface of the connecting rod 507 near both the upper and lower ends. A threaded rod 509 is fixedly connected to both the upper and lower ends of the connecting rod 507. A second bevel gear is fixedly installed in the middle of the outer surface of the connecting rod 507 near the upper end. 506, the second bevel gear 506 meshes with the first bevel gear 504; a rectangular locking block 513 is threaded onto the outer surface of the threaded rod 509; a first groove 510 is opened on both the upper and lower surfaces of the rectangular rod 516; a rectangular sliding groove 511 is opened at the lower end of both ends of the first groove 510; a rectangular slider 512 is slidably installed in the rectangular sliding groove 511; a rectangular slider 512 is fixedly installed at the lower end of both ends of the rectangular locking block 513; a rectangular locking groove 515 is opened at the other end of the upper surface of the first sliding groove 514. When it is necessary to disassemble the filter screen 301, first unscrew the external water pipe 4, then rotate the rotating block 501 to make the rectangular locking block 513 disengage from the rectangular locking groove 515 opened at the other end of the upper surface of the first sliding groove 514 and retract into the first groove 510; then pull the rotating block 501 outward to drive the rectangular rod 516 to slide to one end in the first sliding groove 514, thereby disassembling the filter screen 301, which is simple and convenient.

[0022] It should be noted that this utility model is a water purifier that facilitates filter replacement. When the filter 301 needs to be disassembled, first unscrew the external water pipe 4, then rotate the rotating block 501, causing the rotating block 501 to drive the rotating rod 502 to rotate on the first bearing 503, causing the first bevel gear 504 fixedly installed on the other end of the rotating rod 502 to rotate. Because the first bevel gear 504 meshes with the second bevel gear 506, it drives the connecting rod 507 to rotate on the second bearing 508, causing the connecting rod 507 to rotate. The threaded rod 509, which is fixedly connected to the upper and lower surfaces, rotates, causing the rectangular locking block 513, which is threaded on the outer surface of the threaded rod 509, to drive the rectangular slider 512, which is fixedly installed at the lower end of both ends, to slide downward in the rectangular slide groove 511 until the rectangular locking block 513 disengages from the rectangular locking groove 515 opened at the other end of the upper surface of the first slide groove 514 and retracts into the first groove 510. Then, the rotating block 501 is pulled outward, causing the rectangular rod 516 to slide to one end in the first slide groove 514, thereby removing the filter screen 301. This is simple and convenient.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
