Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a washable filter structure with a linked handle. Background Technology

[0002] The water purifier filter cartridge is the most crucial component of a water purifier. Its function is to remove impurities, pollutants, and harmful substances from the water, providing safe and clean drinking water. Currently, many household water purifiers on the market use "Korean-style quick-connect filter cartridges." Because they lack a corresponding mechanical locking structure, if the insertion is not secure, the interface may loosen under high water pressure, vibration, moving the machine, or water hammer impact. Furthermore, frequent insertion and removal can cause wear on the clips or aging of the plastic, making them prone to loosening. Other types use mechanical snap-fit ​​connections, which can lead to problems such as the clips not retracting synchronously when disassembling from both sides, causing the filter cartridge to become stuck or unable to be pulled out.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 , 2 As shown in Figures 3, 4, 5, 6, 7, 8, and 9, this utility model provides a technical solution: a washable linkage handle filter element structure, comprising: a filter element housing 13, a central tube 7 installed inside the filter element housing 13, and filter media 6 sleeved on the outside of the central tube 7. The filter element is designed with a central tube 7 structure inside, and through the sealed connection between the central tube 7 and the filter element housing 13, an additional sewage discharge path is added to the water path inside the filter element, making the filter element have a longer service life and better performance during use. A sewage discharge port is fixedly connected to the end of the filter element housing 13, and the central tube 7 is connected to the sewage discharge port; a lower end cover 8 is installed at one end of the filter element housing 13, and there is a rib gap between the lower end cover 8 and the filter element housing 13, through which water can enter the central tube 7; the filter element is installed on the whole machine, and the whole machine is equipped with a faucet and a sewage discharge valve accessory. When the faucet is opened, the sewage discharge... When the drain valve is closed, water inside the filter element can only enter through the inlet and exit through the purified water outlet. Since the purified water outlet has been filtered by the internal filter media, the filtration effect is achieved. When the faucet is closed and the drain valve is opened on a timer, there is no sealing pressure at the drain outlet. The water inside enters through the inlet, passes through the central pipe, and exits through the drain outlet, thus rinsing the surface of the filter media. One end of the lower cover 8 is fixedly connected to the filter element cover 9. The end of the filter element cover 9 is rotatably connected to two handles 10. The ends of the two handles 10 are fixedly connected to meshing gears 20. The middle of the filter element cover 9 is slidably connected to a buckle 12. The middle of the gear 20 is fixedly connected to a swing rod 17 for driving the buckle 12. The swing rod 17 is rotatably connected to the filter element cover 9. When the handles 10 are rotated to be perpendicular to the filter element cover 9, the swing rod 17 pushes the buckle 12 toward the center of the filter element cover 9.

[0027] It should be noted that in this embodiment, the filter media 6 mainly functions to filter tap water or raw water, intercepting and removing residual chlorine, impurities, and large particles such as silt from the water; two types of sealing rings are fitted at the end of the central tube, which, through compression, form an interference fit with the filter element housing 13 and the lower end cover 8 to form a seal, thus separating the wastewater inside the filter element from the purified water; the lower end cover 8 is fixed to the filter media 6 by hot melt adhesive to prevent the raw water and purified water from mixing, and is connected to the central tube 7 through the compression interference fit of the sealing ring to prevent the wastewater from mixing with the purified water; the filter element cover 9 is connected to the filter element housing 13 by spin welding. 3. The connection forms an independent cavity for storing water before and after filtration. The bottom surface is fixed to the filter cover by buckles and gap fit, forming a fixed and disassembly structure with the whole machine. Gears 20 are installed at both ends of the handle 10. One end of the gear 20 is equipped with an unlocking part to drive the buckle 12 to retract. The handles 10 are connected to each other by the meshing of the gears 20. When one end of the handle 10 is rotated, the other end of the handle rotates at the same angle with the gear structure, achieving a linkage state. This avoids problems such as jamming or inability to pull out the filter when disassembling or assembling the filter due to asynchrony.

[0028] In one embodiment, the filter element housing 13 is fixedly connected to an inlet and a purified water outlet at its end. A stop valve is installed in the middle of both the inlet and the purified water outlet to ensure that the inlet is unidirectionally inlet and the purified water outlet is unidirectionally outlet. A welded cover plate 1 is installed at the end of both the inlet and the purified water outlet. An upper cover 5 for fixing the filter media 6 is fixedly connected inside the filter element housing 13.

[0029] It should be noted that in this embodiment, the welding cover plate 1 is welded to the barrel shell 13 by ultrasonic process, mainly to fix the water stop valve rod to the barrel shell 13 and prevent it from popping off. The outer side of the upper cover 5 is fitted with a sealing ring, which forms a seal by compressing the sealing ring and interfering with the filter element shell 13, so as to separate the raw water and purified water inside the filter element and prevent water from crossing. The upper cover is fixed to the filter material 6 by hot melt adhesive to avoid water crossing inside.

[0030] In one embodiment, both ends of the filter cover 9 have sliding holes for the buckle 12 to slide. Guide slide rods are fixedly connected to the positions of the corresponding sliding holes of the filter cover 9. The buckle 12 is slidably connected to the guide slide rods. One end of the buckle 12 is fixedly connected to a limit post 15. A spring 16 is installed between the corresponding limit posts 15. A plastic plate for pressing the spring 16 is fixedly connected to the middle of the filter cover 9 by bolts.

[0031] It should be noted that in this embodiment, when the handle is not rotated, the spring between the buckles 12 causes the buckles 12 to extend outward, thereby achieving the effect of fixing the filter element; 13 is the filter element housing, which is fixedly connected to the filter element cover 9 by spin welding to form an independent filter element cavity. The top is fixedly connected to the water stop valve stem assembly 2, the spring 3 and the water stop valve seat 4 by ultrasonic welding to form a water stop structure and achieve the water stop function of the filter element.

[0032] In one embodiment, the swing rod 17 has an L-shaped structure, with a slide rod 18 fixedly connected to the bottom of one end of the swing rod 17, an arc-shaped groove 14 for the slide rod 18 to fit at the bottom of the buckle 12, and an arc-shaped plate 19 for the swing rod 17 to fit at the top of the buckle 12.

[0033] It should be noted that in this embodiment, when the multiple latches 12 are retracted, the handle 10 is rotated downwards, and the handle 10 drives the other handle 10 to rotate through the gear 20. During this period, the gear 20 drives the slide rod 18 to rotate through the swing rod 17, so that the slide rod 18 moves upward from one end of the arc groove 14. When the ends of the slide rod 18 and the swing rod 17 make oblique contact with the arc plate 19, under the action of compression, the latches 12 slide along the guide slide rod in the sliding hole, so that the latches 12 retract into the filter cover 9, thereby disassembling the filter element. During the retraction process, the two latches 12 compress the spring 16. After the handle 10 is reset, the latches 12 slide back to their original position under the elastic force of the spring 16.

[0034] In one embodiment, a decorative cover 11 is detachably mounted on the center of the filter element cover 9.

[0035] It should be noted that in this embodiment, the decorative cover 11 is fixed to the filter cover 9 by a snap-fit ​​method, mainly for aesthetic purposes.
