Description

Technical Field

[0001] This utility model relates to the field of flip-top type filter cartridge replacement household water purifiers, specifically a flip-top type filter cartridge replacement household water purifier. Background Technology

[0002] With the improvement of residents' living standards and the enhancement of health awareness, household water purifiers have become a common device for improving drinking water quality.

[0003] Replacing the filter cartridges in existing household water purifiers is cumbersome and lacks user-friendliness. Most water purifiers require removing the fixed cover on the side or bottom of the cabinet to take out the filter cartridges, and the disassembly process requires tools such as screwdrivers, which is not user-friendly. Some products with top covers have complicated locking mechanisms, and the filter cartridges lack dedicated lifting parts, making them easy to slip and fall out when removing them. In addition, there is no guiding and positioning structure for the filter cartridges during installation, which can easily lead to misalignment.

[0004] Therefore, a new type of flip-top filter replacement household water purifier needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a flip-top type filter cartridge replacement household water purifier to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flip-top type filter cartridge replacement household water purifier, including a housing, an operation panel on one side of the housing, a housing cover hinged to the top of the housing, a locking pin fixedly connected to the housing cover, a latch fixedly connected to one side of the housing, the locking pin engaging with the latch, and a cavity inside the housing containing a water purification component.

[0007] Preferably, the water purification component includes a pre-filter, a core filter, and a post-filter. The top of the pre-filter, core filter, and post-filter is fixedly connected to a lifting handle. The inner wall of the cavity is provided with two sliding grooves, and a ring is slidably connected to the sliding grooves. The pre-filter, core filter, and post-filter are fixedly connected by a soft water pipe.

[0008] Preferably, a water inlet pipe is fixedly connected to one end of the box.

[0009] Preferably, a water outlet is fixedly connected to the other end of the tank.

[0010] Preferably, a drawer is slidably connected to the bottom of the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this utility model, a multi-stage filtration system consisting of a pre-filter, a core filter, and a post-filter, combined with a continuous water path formed by a soft water pipe, achieves multiple deep purifications of the raw water, effectively improving the quality of the effluent. The flip-top cover design, along with a locking pin and buckle structure, ensures both sealing during use and easy opening of the cover. The pull handle on the top of the filter element and the guiding and fixing structure of the sliding groove and ring facilitate filter element replacement. Attached Figure Description

[0019] 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.

[0020] All electronic components in this application are controlled by an external controller.

[0021] Example 1

[0022] Please refer to Figure 1-5As shown, this utility model provides a flip-top type filter cartridge replacement household water purifier, including a housing 1. An operation panel 2 is provided on one side of the housing 1 for user operation of the water purifier and display of its working status. A lid 3 is hinged to the top of the housing 1, and a locking pin 4 is fixedly connected to the lid 3. A latch 5 is fixedly connected to one side of the housing 1. The locking pin 4 and the latch 5 engage, allowing the lid 3 to be flipped open for easy user access to replace the internal filter cartridge. When closed, the lid 3 and the housing 1 form a closed space. A cavity 6 is provided inside the housing 1, and a water purification component is located within the cavity 6.

[0023] Specifically, the water purification components include a pre-filter 7, a core filter 8, and a post-filter 9, forming a multi-stage filtration system that improves water quality. A lifting handle 10 is fixedly connected to the top of each filter. Two sliding grooves 11 are provided on the inner wall of the cavity 6, with a ring 12 slidably connected to each groove. The sliding grooves 11 are located on the inner wall of the housing 1, and the ring 12 connects to the filter element and slides along the groove, providing guidance and fixation to ensure accurate and stable installation of the filter element and prevent shaking from affecting the water circuit connection. The pre-filter 7, core filter 8, and post-filter 9 are fixedly connected by a soft water pipe 13, forming a continuous water channel for water flow between the filter elements.

[0024] One end of the housing 1 is fixedly connected to a water inlet pipe 14, which is used to connect to an external water source and introduce the raw water to be purified into the water purifier.

[0025] Based on the above embodiments, specifically, the other end of the box 1 is fixedly connected to a water outlet 15, which is used for the purified water outlet to export the water that has been filtered through multiple layers.

[0026] Specifically, a drawer 16 is slidably connected to the bottom of the housing 1. The drawer 16 can be slidably pulled out to collect wastewater generated during the operation of the water purifier.

[0027] Working principle: Raw water enters the internal cavity 6 of the tank 1 through the inlet pipe 14, and flows sequentially through the pre-filter 7, core filter 8 and post-filter 9 connected by the soft water pipe 13. The pre-filter 7 first filters out large particles of impurities, the core filter 8 deeply purifies and removes harmful substances such as microorganisms and heavy metals, and the post-filter 9 further optimizes the taste of the water. The sliding groove 11 and the ring 12 cooperate to ensure the stable installation of the filter and ensure smooth water flow. The purified water is finally output through the outlet 15. The tank cover 3 is fixed by the locking pin 4 and the buckle 5 to form a closed space. When the filter needs to be replaced, the tank cover 3 is opened and the filter can be easily taken out with the help of the lifting handle 10.

[0028] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
