Description

Technical Field

[0001] This utility model belongs to the field of water treatment technology, and relates to a filter element, specifically to a top-out structure of a filter element. Background Technology

[0002] In response to the problem of secondary pollution of tap water and the presence of harmful substances in tap water due to raw water pollution, more and more water purifiers are being used.

[0003] A water purifier, also called a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water according to usage requirements. Its function is to remove suspended solids, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, and other contaminants from the water. The filter cartridge, as a key component of the water purifier, needs to be cleaned and replaced promptly after a period of use. However, filter cartridge replacement often presents difficulties, making it time-consuming and laborious, and even more challenging for users to replace filters themselves. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a filter element ejection structure that is simple in structure and easy to operate, in view of the above-mentioned technical status.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a filter element ejection structure, including a filter element and a water channel plate, characterized in that: a water channel adapter plate is fixed on the water channel plate, the water channel plate is connected to the end of the filter element through the water channel adapter plate, a retractable top block is installed on the water channel plate adapter plate, and a concave cavity for the top block to slide and extend is formed on the inner side of the water channel plate corresponding to the position of the top block. A spring is provided in the concave cavity to abut against the top block. When the filter element is connected to the water channel plate, the top block is in a retracted state. When the filter element is separated from the water channel plate, the top block ejects the filter element under the action of the spring.

[0006] As an improvement, the water circuit plate has a recessed groove on one side corresponding to the filter element for embedding the water circuit adapter plate. The water circuit adapter plate is embedded in the groove and fixed to the water circuit plate by screws. The top block is a cylindrical structure with a sealed outer end and an open inner end. The water circuit adapter plate has a circular hole for the top block to pass through and slide. The inner open end of the top block has an outwardly extending protrusion. The top block is limited by the protrusion and the circular hole of the water circuit adapter plate.

[0007] Furthermore, the top blocks are a plurality of evenly spaced blocks arranged along the circumference of the water channel plate adapter plate, and the water channel plate has a plurality of corresponding cavities. The inner diameter of the cavity matches the outer diameter of the top block's convex edge. The length of the cavity can accommodate the top block to be completely retracted into the water channel plate. One end of the spring is inserted into the inner hole of the top block, and the other end abuts against the inner wall of the cavity for support, so that the top block always has a tendency to extend outward.

[0008] Furthermore, the water circuit plate has three water circuits that are respectively connected to the inlet, outlet and wastewater discharge port of the filter element. The water circuit adapter plate has a hollow cylinder protruding from it that is inserted into the three ports of the filter element, and a water stop valve core is installed inside the hollow cylinder.

[0009] Finally, the water circuit adapter plate forms part of the filter element mounting base.

[0010] Compared with existing technologies, the advantages of this utility model are as follows: the water circuit adapter plate is fixed to the water circuit plate and is equipped with a top block and a spring. When the filter element is removed, the top block pushes the filter element out through the spring, making the filter element removal smoother and less strenuous. This utility model has a simple structure, is easy and labor-saving to operate, and greatly facilitates users to replace the filter element themselves. Attached Figure Description

[0013] Figure 3 This is an exploded view of an embodiment of the present utility model. Detailed Implementation

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , 2 As shown in Figure 3, a filter element ejection structure includes a filter element 1 and a water channel plate 2. The water channel plate 2 is connected to the end of the filter element 1 through a water channel adapter plate 3. The water channel adapter plate 3 is fixed on the water channel plate 2. A retractable top block 4 is installed on the water channel adapter plate 3. A recess 21 is formed on the inner side of the water channel plate 2 corresponding to the position of the top block 4, allowing the top block 4 to slide and extend. A spring 5 is provided in the recess 21 to abut against the top block 4. When the filter element 1 is connected to the water channel plate 2, the top block 4 is in a retracted state. When the filter element 1 is separated from the water channel plate 2, the top block 4 ejects the filter element 1 under the action of the spring 5.

[0016] The specific structure is as follows: The water channel plate 2 has a recessed groove 8 on one side corresponding to the filter element 1, into which the water supply adapter plate 3 is embedded. The water supply adapter plate 3 is embedded in the groove 8 and fixed to the water channel plate 2 by screws 7. The top block 4 is a cylindrical structure with a sealed outer end and an open inner end. The water supply adapter plate 3 has a circular hole 31 for the top block 4 to pass through and slide. The inner open end of the top block 4 has an outwardly extending protruding edge 41, which abuts against and limits the top block 4 to the circular hole 31 of the water supply adapter plate 3. In this embodiment, multiple top blocks 4 are evenly spaced along the circumference of the water supply adapter plate 3, and multiple corresponding cavities 21 are formed in the water channel plate 2. In this embodiment, six cavities are used. The inner diameter of the concave cavity 21 matches the outer diameter of the protruding edge of the top block 4. The length of the concave cavity 21 is sufficient to accommodate the top block 4 fully retracted into the water channel plate 2. One end of the spring 5 is inserted into the inner hole of the top block 4, and the other end abuts against the inner wall of the concave cavity 21 for support, giving the top block 4 a tendency to always extend outward. The water channel plate 2 has three water channels that connect to the inlet, outlet, and wastewater discharge port of the filter element 1, respectively. The water channel adapter plate 3 has a hollow cylinder 32 protruding from it that inserts into the three ports of the filter element 1. A stop valve core 6 is installed inside the hollow cylinder 32. The water channel structure inside the water channel plate 2 and the water channel connection and fit with the filter element 1 are consistent with the prior art and will not be described in detail here. The water channel adapter plate 3 usually forms part of the filter element mounting base and is disc-shaped for easy manufacturing.

[0017] Before filter element 1 is ejected, such as Figure 1 As shown, the top block 4 retracts, and the spring 5 is in a compressed state; when the filter element 2 separates from the water circuit plate 2, as... Figure 2 As shown, the top block 4 descends under the action of the spring 5, pushing the filter element 1 out, making the filter element 1 exit more smoothly and effortlessly, and making it convenient for users to replace the filter element.

[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
