Description
Technical Field
[0001] This invention relates to the field of catalyst storage, and more particularly to a household multi-layer filter water purification device that facilitates filter replacement. Background Technology
[0002] Water purification equipment refers to equipment that produces purified water. Also called water purifiers or water quality purifiers, it's a water treatment device that deeply filters and purifies water according to usage requirements. The water purifiers commonly referred to are generally small-scale purifiers used in homes. Household multi-layer filter water purifiers can effectively filter out impurities from the water.
[0003] After a period of use, existing household multi-layer filter water purifiers will have tiny impurities adhering to the outer surface of the multi-layer filter cartridges, causing blockage of the filter pores and reducing the filtration efficiency, thus affecting normal water purification. Therefore, the multi-layer filter cartridges need to be replaced regularly. However, the multi-layer filter cartridges are fixed inside the filter chamber using multiple sets of mounting bolts. Each time the multi-layer filter cartridge needs to be replaced, several fixing bolts must be removed before the multi-layer filter cartridge can be taken out. Moreover, it is not convenient for staff to remove the multi-layer filter cartridge when it is fully inserted into the filter chamber. Special tools are required to clamp it out, making the entire replacement process very cumbersome. After replacement, the multi-layer filter cartridges have been touched by people, and some bacteria inevitably adhere to their surface, so it cannot be guaranteed that the multi-layer filter cartridges are in a sterile state after replacement.
[0004] Therefore, it is necessary to provide a new household multi-layer filter water purification device that is easy to replace filter cartridges to solve the above-mentioned technical problems. Summary of the Invention

[0008] Preferably, a sealing ring is provided on the side wall of the cover, and the specifications of the sealing ring are the same as those of the side wall of the filter chamber opening.
[0009] Preferably, the lower end face of the cover is provided with a groove, a waterproof glass is installed and connected in the groove, and an ultraviolet disinfection lamp is installed and connected inside the groove.
[0010] Preferably, one of the vertical plates is provided with a groove, the sliding sleeve is provided with a protrusion, the protrusion is slidably connected to the groove, and a touch delay switch is installed and connected on one end of the groove wall.
[0011] Preferably, a convenient installation mechanism is provided between the multi-layer filter element and the inner wall of the filter chamber. The convenient installation mechanism includes two side cylinders, both of which are fixedly connected to the inner wall of the filter chamber. Both ends of the multi-layer filter element are fixedly connected to a pestle. Both side cylinders have elongated holes. The two pestles are slidably connected to the two side cylinders respectively. The upper end of both elongated holes has a wide cylindrical groove. Both pestles are fitted with lifting springs. One end of each lifting spring is connected to the two pestles respectively. The two lifting springs are inserted into the two wide cylindrical grooves respectively.
[0012] Preferably, both of the two inserts are provided with fixing grooves, and both of the two side cylinders have transverse grooves on the inner walls of their elongated holes. Each of the two transverse grooves is provided with a convenient locking mechanism. The convenient locking mechanism includes a fixing ring, which is fixedly connected to the inner wall of the transverse groove. A pin is slidably connected to the fixing ring. One end of the pin is designed with an angled head, and the other end of the pin is connected to a magnet. A small spring is fitted on the pin, with one end of the small spring connected to the fixing ring and the other end of the small spring connected to the magnet.
[0013] Preferably, the outer wall of the filter chamber is provided with an automatic unlocking mechanism, which includes two side rods.

The magnetic poles of the two magnetic sheets are opposite to those of the two magnetic blocks.
[0014] Compared with related technologies, the household multi-layer filter water purifier provided by the present invention, which facilitates filter replacement, has the following beneficial effects:
[0015] 1. This invention provides a household multi-layer filter water purifier that facilitates filter replacement. By rotating the handle at the top of the rotating shaft, the rotation of the rotating shaft drives the threaded sleeve to move the cover. The other end of the cover causes the sliding sleeve to slide relative to the fixed vertical rod, so that the cover can be stably moved up away from the opening above the filter chamber, making it easy to open the filter chamber and thus facilitating the subsequent replacement of the multi-layer filter.
[0016] 2. This invention provides a household multi-layer filter water purifier that facilitates filter replacement. By sliding an arched ring so that its two ends slide relative to two side rods, the arched ring causes the magnetic plates on its inner sides to move upward and approach the two magnetic blocks. This attracts the two magnetic blocks and causes the two pins to slide relative to the two fixed rings. This allows one end of the two pins to slide away from the fixed grooves on the two pins, thus automatically unlocking the multi-layer filter and facilitating filter replacement.
[0017] 3. This invention provides a household multi-layer filter water purifier that is easy to replace the filter cartridge. By restoring the elastic deformation of two lifting springs, the two inserts slide relative to the two side cylinders. The two inserts together drive the multi-layer filter cartridge to pop out directly, which can be directly picked up and replaced by the staff without the need for tools, which is very convenient.
[0018] 4. This invention provides a household multi-layer filter water purifier that facilitates filter replacement. Two inserts on the multi-layer filter slide into the interior of two side cylinders, pressing the filter downwards. When the lower ends of the two inserts abut against the inclined surfaces of one end of the two pins, the two pins slide relative to the two fixing rings until one end coincides with the two fixing grooves. Then, two small springs restore their elastic deformation, causing the two pins to slide in the opposite direction relative to the two fixing rings into the two fixing grooves. This allows for quick and convenient installation and locking of the multi-layer filter.
[0019] 5. This invention provides a household multi-layer filter water purifier that facilitates filter replacement. The protrusion on the sliding sleeve slides in the groove on one side of the vertical plate until it abuts against the touch delay switch at its bottom. This automatically controls the ultraviolet disinfection lamp in the waterproof glass to work for a period of time, sterilizing the multi-layer filter after installation. No manual control is required; sterilization is performed automatically after replacement, effectively keeping the multi-layer filter in a sterile state. Attached Figure Description

Detailed Implementation
[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0029] Please refer to the following: Figures 1 to 7 A household multi-layer filter water purifier with easy filter replacement includes: a housing 1, with multiple mounting plates 11 on the outer wall of the housing 1; an opening on the front wall of the housing 1, with a door 12 installed at the opening; a water inlet pipe 13 on the upper wall of the housing 1; a water outlet pipe 14 on the lower wall of the housing 1; a filter chamber 2 inside the housing 1; a cover 3 at the upper opening of the filter chamber 2; a central connector 31 on the cover 3; and the central connector 31 connected to the water inlet pipe 13 via a connecting hose 4. The filter chamber 2 is equipped with multiple filter elements 5; the convenient opening mechanism 6 includes two vertical plates 61, both of which are fixedly connected to the inner wall of the housing 1. A fixed vertical rod 62 is fixedly connected to one vertical plate 61, and a sliding sleeve 63 is slidably connected to the fixed vertical rod 62. The sliding sleeve 63 is fixedly connected to one end of the cover 3. A rotating shaft 64 is rotatably connected to the other vertical plate 61. The rotating shaft 64 is provided with a threaded sleeve 65, which is fixedly connected to the other end of the cover 3. A handle 66 is installed and connected to the upper end of the rotating shaft 64.
[0030] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the threaded sleeve 65 has a threaded opening, the rotating shaft 64 is a threaded rod, and the threaded sleeve 65 is threadedly connected to the rotating shaft 64.
[0031] It should be noted that: rotating the handle 66 at the upper end of the rotating shaft 64 causes the rotating shaft 64 to drive the threaded sleeve 65 to move the cover 3. The other end of the cover 3 drives the sliding sleeve 63 to slide relative to the fixed vertical rod 62, thus achieving stable movement of the cover 3.
[0032] refer to Figure 2 and Figure 4As shown, a sealing ring 32 is provided on the side wall of the cover 3, and the specifications of the sealing ring 32 are the same as those of the side wall of the filter chamber 2.
[0033] It should be noted that the sealing ring 32 can make the cover 3 fit more tightly with the filter chamber 2.
[0034] refer to Figure 2 and Figure 4 As shown, the lower end face of the cover 3 has a groove, a waterproof glass 33 is installed and connected in the groove, and an ultraviolet disinfection lamp 34 is installed and connected inside the groove; a groove is provided on a vertical plate 61, a protrusion is provided on the sliding sleeve 63, the protrusion is slidably connected to the groove, and a touch delay switch 611 is installed and connected on one end of the groove wall.
[0035] It should be noted that the protrusion on the sliding sleeve 63 slides in the groove on the vertical plate 61 on one side until it abuts against the touch delay switch 611 at its bottom, which automatically controls the ultraviolet disinfection lamp 34 in the waterproof glass 33 to work for a period of time to sterilize and disinfect the multi-layer filter element 5 after installation.
[0036] refer to Figure 2 and Figure 5 As shown, a convenient installation mechanism 7 is provided between the multi-layer filter element 5 and the inner wall of the filter chamber 2. The convenient installation mechanism 7 includes two side cylinders 71, both of which are fixedly connected to the inner wall of the filter chamber 2. Both ends of the multi-layer filter element 5 are fixedly connected to the insertion rods 72. Both side cylinders 71 are provided with elongated holes. The two insertion rods 72 are slidably connected to the two side cylinders 71 respectively. The upper end of the two elongated holes is provided with a wide cylindrical groove. Both insertion rods 72 are fitted with lifting springs 73. One end of the two lifting springs 73 is connected to the two insertion rods 72 respectively. The two lifting springs 73 are inserted into the two wide cylindrical grooves respectively.
[0037] It should be noted that the two inserts 72 on the multi-layer filter element 5 slide into the interior of the two side cylinders 71, pressing the multi-layer filter element 5 down and causing the two lifting springs 73 to undergo elastic deformation.
[0038] refer to Figure 5 and Figure 6 As shown, both pins 72 are provided with fixing grooves, and both side cylinders 71 have transverse grooves on the inner walls of their elongated holes. Both transverse grooves are provided with convenient locking mechanisms 8. The convenient locking mechanism 8 includes a fixing ring 81, which is fixedly connected to the inner wall of the transverse groove. A pin 82 is slidably connected to the fixing ring 81. One end of the pin 82 is designed with a beveled head, and the other end of the pin 82 is connected to a magnet 83. A small spring 84 is sleeved on the pin 82. One end of the small spring 84 is connected to the fixing ring 81, and the other end of the small spring 84 is connected to the magnet 83.
[0039] It should be noted that when the lower ends of the two pins 72 abut against the inclined surfaces of one end of the two pins 82, the two pins 82 slide relative to the two fixed rings 81, and the two small springs 84 undergo elastic deformation.
[0040] When one end of the two pins 82 coincides with the two fixing slots, the two small springs 84 restore their elastic deformation, causing the two pins 82 to slide in the opposite direction relative to the two fixing rings 81 until one end of the two pins 82 slides into the two fixing slots, thus quickly realizing the installation and locking of the multi-layer filter element 5.
[0041] refer to Figure 2 and Figure 7 As shown, an automatic unlocking mechanism 9 is provided on the outer wall of the filter chamber 2. The automatic unlocking mechanism 9 includes two side rods 91, both of which are fixedly connected to the outer walls of both sides of the filter chamber 2. An arched ring 92 is provided between the two side rods 91. The two ends of the arched ring 92 are slidably connected to the two side rods 91 respectively. Magnetic plates 93 are installed and connected on the inner ring walls of both ends of the arched ring 92. The magnetic poles of the two magnetic plates 93 are opposite to those of the two magnetic blocks 83.
[0042] It should be noted that: the sliding arched ring 92 slides at both ends relative to the two side rods 91, and the arched ring 92 drives the magnetic pieces 93 on its inner sides to move upward accordingly;
[0043] When the two magnetic pieces 93 slide close to the two magnetic blocks 83, they attract the two magnetic blocks 83 and drive the two pins 82 to slide relative to the two fixed rings 81. The two small springs 84 undergo elastic deformation, causing one end of the two pins 82 to slide away from the fixed grooves on the two pins 72.
[0044] The two lifting springs 73 return to their elastic deformation, causing the two inserts 72 to slide relative to the two side cylinders 71. The two inserts 72 together drive the multi-layer filter element 5 to pop out directly, which can be directly picked up and replaced by the staff.
[0045] The working principle of a household multi-layer filter water purifier that facilitates filter replacement provided by the present invention is as follows: When it is necessary to replace the multi-layer filter 5, open the shell door 12 on the front side wall of the shell 1, rotate the handle 66 at the upper end of the rotating shaft 64, so that the rotation of the rotating shaft 64 drives the threaded sleeve 65 to move the cover shell 3. The other end of the cover shell 3 drives the sliding sleeve 63 to slide relative to the fixed vertical rod 62, so that the cover shell 3 can be stably moved upward away from the cavity opening above the filter chamber 2, making it easy to open the filter chamber 2 and facilitate the subsequent replacement of the multi-layer filter 5.
[0046] Slide the arched ring 92 so that its two ends slide relative to the two side rods 91. The arched ring 92 drives the magnetic pieces 93 on its two sides to move upward. When the two magnetic pieces 93 slide close to the two magnetic blocks 83, they attract the two magnetic blocks 83 and drive the two pins 82 to slide relative to the two fixed rings 81. The two small springs 84 undergo elastic deformation, causing one end of the two pins 82 to slide away from the fixed grooves on the two pins 72. The two lifting springs 73 restore their elastic deformation, causing the two pins 72 to slide relative to the two side cylinders 71. The two pins 72 together drive the multi-layer filter element 5 to pop out directly. The staff can directly pick it up and replace it without the need for tools, which is very convenient.
[0047] After placing the new multi-layer filter element 5 into the filter chamber 2, the two inserts 72 on the multi-layer filter element 5 slide into the two side cylinders 71, pressing the multi-layer filter element 5 down. This causes the two lifting springs 73 to elastically deform. When the lower ends of the two inserts 72 abut against the inclined surfaces of one end of the two pins 82, the two pins 82 slide relative to the two fixing rings 81, and the two small springs 84 elastically deform. When one end of the two pins 82 coincides with the two fixing grooves, the two small springs 84 return to their elastic deformation, causing the two pins 82 to slide in the opposite direction relative to the two fixing rings 81 until one end of the two pins 82 slides into the two fixing grooves. This quickly and easily achieves the installation and locking of the multi-layer filter element 5.
[0048] After installation, the handle 66 at the top of the shaft 64 is rotated in the opposite direction. The rotation of the shaft 64 drives the threaded sleeve 65 to move the cover 3. The other end of the cover 3 drives the sliding sleeve 63 to slide relative to the fixed vertical rod 62, so that the cover 3 can move down stably and abut against the cavity opening above the filter chamber 2. The sealing ring 32 on the cover 3 abuts against the side wall of the cavity opening, so that the filter chamber 2 is in a sealed state. The protrusion on the sliding sleeve 63 slides in the groove on one side of the vertical plate 61 until it abuts against the touch delay switch 611 at its bottom. The ultraviolet disinfection lamp 34 in the waterproof glass 33 is automatically controlled to work for a period of time to sterilize the multi-layer filter element 5 after installation. No manual control is required. Sterilization can be performed automatically after replacement, effectively ensuring that the replaced multi-layer filter element 5 is in a sterile state.
[0049] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
