Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, and in particular to a magnetized water lubrication device for a water negative oxygen ion environmental purifier. Background Technology

[0002] Air purifiers with humidification functions can purify and humidify the air at the same time, meeting multiple customer needs and thus gaining popularity among more and more users.

[0003] Chinese utility model patent application number 201821729016.6, entitled "A Humidifying Air Purifier," discloses a technical solution in which a humidifying filter is installed inside an air filter. In this solution, a water tank is located at the bottom of the housing, and an air filter and a humidifying filter are sequentially arranged on the side wall of the housing from the outside in. During use, a water pump draws water from the tank to the top of the humidifying filter support. The water leaks through a drain hole at the top of the support onto the humidifying filter. Thus, purified air passes through the humidifying filter, carrying the moisture with it out of the purifier, achieving the function of humidifying the room. However, this technology has some technical problems: because the humidifying filter absorbs microorganisms from the air and remains constantly moist, if it is not cleaned in time, bacteria will grow, posing a health hazard. Therefore, the humidifying filter needs to be removed and cleaned regularly (e.g., once every week or two). Because the humidifier filter is located inside the air filter, the air filter must be removed first before the humidifier filter can be taken out. This not only makes the removal and installation of the humidifier filter very time-consuming and laborious, but also makes the air filter more susceptible to damage due to accidents during the removal and installation process, thus increasing the user's operating costs.

[0004] Given the aforementioned technical problems in the existing technology, the applicant believes it is necessary to make technical improvements to provide a humidifying air purifier with a humidifying filter that is easier to install and remove. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems and shortcomings, and to provide a magnetized humidification device for a water negative oxygen ion environmental purifier.

Furthermore, the housing has disassembly and assembly holes that communicate with the disassembly and assembly channels, and a sealed door is fastened to these holes. This allows the humidifying filter to be removed by opening the sealed door, greatly facilitating cleaning or replacement of the humidifying filter and significantly improving the ease of use and hygiene of the humidification device. In addition, the magnetic ring can enhance the atomization effect of the water, thereby improving the humidification effect of the humidification device.

[0006] The technical solution of this utility model is implemented as follows: A magnetized water humidification device for a water negative oxygen ion environmental purifier includes a shell, a water tank located at the bottom of the shell, a submersible pump, a humidifying filter, and an air filter assembly placed inside the water tank; its feature is that it also includes a support assembly located above the water tank, the support assembly having crisscrossing and interconnected disassembly and assembly channels and an air filter channel formed thereon; the humidifying filter is detachably installed on the air filter channel; the air filter assembly is located on the side wall of the shell next to the humidifying filter; the shell has a disassembly and assembly hole communicating with the disassembly and assembly channel, and a sealing door is fastened to the disassembly and assembly hole, and a sealing gasket is also provided between the sealing door and the disassembly and assembly hole; the support assembly has a water pipe connected to the submersible pump and a water permeable hole for water supply; and a magnetic ring capable of magnetizing the water is fitted on the water pipe.

[0008] Furthermore, a support column is provided at the corner of the water tank body; a positioning protrusion is provided at the top of the support column, and an insertion hole is provided at the end of the lower positioning groove. The lower bracket is fitted onto the positioning protrusion through the insertion hole and overlaps the upper part of the water tank.

[0009] Furthermore, the top of the upper bracket is provided with a fitting hole seat, and a fitting stud is inserted into the housing and embedded in the fitting hole seat. The upper bracket is fixedly installed on the housing by screwing a screw through the fitting hole seat into the fitting stud.

[0010] Furthermore, the upper support is provided with a drain groove at the top and an upper positioning groove at the bottom; the water-permeable hole is provided to penetrate the drain groove and the upper positioning groove; and a waterproof plate is placed at the opening of the drain groove.

[0011] Furthermore, the water pipe is positioned between the lower support and the submersible pump, and between the lower support and the upper support, with the water outlet end of the water pipe connected to the drain trough.

[0012] Furthermore, the two opposite holes of the disassembly and assembly holes are respectively provided with insertion holes and fastening holes, and the two ends of the airtight door are respectively provided with insertion heads and fastening heads; the insertion head can be detachably inserted into the insertion hole, and the fastening head can be detachably fastened to the fastening hole.

This allows the humidifying filter to be installed independently within the housing, allowing users to easily disassemble and install it by opening the sealed door, without needing to disassemble the air filtration assembly. This makes cleaning and replacement of the humidifying filter extremely convenient, greatly improving the user experience. Furthermore, it allows for easy cleaning of the interior of the humidifying device, further preventing bacterial growth and making the device more hygienic and healthy to use. Secondly, by attaching a magnetic ring to the water pipe, when water flows through the ring, it cuts the magnetic lines of force, generating electrical charges and disrupting the water molecule association structure, forming magnetized water with low surface tension. This makes the water easier to atomize, resulting in better air humidification and further improving the product quality of this invention. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] like Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a magnetized humidification device for a water negative oxygen ion environmental purifier, including a housing 1, a water tank 2 disposed at the bottom of the housing 1, a submersible pump 3, a humidifying filter 4, and an air filter assembly 5 placed inside the water tank 2; to achieve the purpose proposed by this utility model, this utility model also includes a support assembly 6 disposed above the water tank 2, the support assembly 6 having crisscrossing and through-flowing disassembly and assembly channels 10 and air filter channels 20; the humidifying filter 4 is detachably installed. The air filter assembly 5 is located on the side wall of the housing 1 next to the humidifying filter 4, on the air filter channel 20. The housing 1 has a disassembly / removal hole 11 that communicates with the disassembly / removal channel 10, and a sealing door 7 is fastened to the disassembly / removal hole 11. A sealing gasket 110 is also provided between the sealing door 7 and the disassembly / removal hole 11. The bracket assembly 6 has a water pipe 63 connected to the submersible pump 3 and a water-permeable hole 64 through which water flows. A magnetic ring 8 that can magnetize water is fitted onto the water pipe 63. In this way, the humidifying filter 4 and the air filter assembly 5 are set relatively independently, and the humidifying filter 4 can be removed separately by opening the sealing door 7, making operation very convenient.

[0027] The magnetic ring 8 can be an external magnetic ring used in current magnetized water processors. To achieve better water magnetization and control costs, a magnetic ring with a magnetic strength of 2000-5000 Gauss can be selected depending on the size of the space. After magnetization, water molecules are more easily atomized, thus providing clean air with suitable humidity.

[0028] like Figure 1 , 3As shown, the support assembly 6 includes an upper support 61 and a lower support 62 arranged side by side. The upper support 61 and lower support 62 are respectively provided with an upper positioning groove 611 and a lower positioning groove 621. The humidifying filter 4 is detachably fitted between the upper positioning groove 611 and the lower positioning groove 621. Thus, an air filtration channel 20 is formed between the upper positioning groove 611 and the lower positioning groove 621, and the disassembly / removal channel 10 and the air filtration channel 20 are arranged in a crisscross pattern. The top and bottom ends of the humidifying filter 4 are respectively inserted into the upper positioning groove 611 and the lower positioning groove 621. This not only allows for quick installation of the humidifying filter 4 on the support assembly 6, but also enables easy disassembly and removal of the humidifying filter 4 through a sliding pull-out mechanism, making it very convenient to use.

[0029] like Figure 3 , 4 As shown in Figures 7 and 8, support columns 21 are provided at the corners of the water tank 2. A positioning protrusion 22 is provided at the top of each support column 21, and an insertion hole 622 is provided at the end of the lower positioning groove 621. The lower bracket 62 is fitted onto the positioning protrusion 22 through the insertion hole 622 and thus overlaps the water tank 2. This allows the lower bracket 62 to be easily installed on top of the water tank 2. Furthermore, during use, the lower bracket 62 can be removed for separate cleaning of the lower bracket 62 and the interior of the water tank 2, thereby improving the hygienic performance of this invention. Further, both the water tank 2 and the lower bracket 62 are square structures. Support columns 21 are provided at the four corners of the water tank 2. Lower positioning grooves 621 are provided on both the left and right sides of the lower bracket 62, and insertion holes 622 are provided at both ends of each positioning groove 621. This allows the lower bracket 62 to be stably installed on top of the water tank 2.

[0030] Furthermore, such as Figure 7 As shown, grooves 623 are provided at both ends of the lower positioning groove 622, and the mounting hole 622 is opened at the bottom of the groove 623. In this way, after the mounting hole 622 is fitted onto the positioning protrusion 22, it can prevent the positioning protrusion 22 from obstructing the smooth sliding and pulling of the humidifying filter 4 in the lower positioning groove 622.

[0031] like Figure 2 , 3 As shown, the upper bracket 61 has a fitting seat 613 on its top, and the housing 1 has a fitting stud 13 that is inserted into the fitting seat 613. The upper bracket 61 is fixedly installed on the housing 1 by screwing a screw through the fitting seat 613 and into the fitting stud 13. In this way, there is no connecting structure between the lower bracket 62 and the upper bracket 61, which simplifies the structure of the bracket assembly 6 and reduces manufacturing costs. On the other hand, it also avoids the connecting post between the lower bracket 62 and the upper bracket 61 from obstructing the airflow within the housing 1, making the airflow smoother.

[0032] like Figure 3 As shown, the upper bracket 61 is provided with a drain groove 612 at its top and an upper positioning slide groove 611 at its bottom; the water permeable hole 64 is provided through the drain groove 612 and the upper positioning slide groove 611; and a waterproof plate 65 is placed over the opening of the drain groove 612. In this way, water is evenly distributed in the drain groove 612 and slowly flows into the humidifying filter 4 through the water permeable hole 64, ensuring uniform water distribution on the humidifying filter 4. The waterproof plate 65 also prevents water in the drain groove 612 from flowing into other parts of the housing 1, such as the motor and circuit board.

[0033] like Figure 3 As shown, in order to place the waterproof membrane 65 sealing cap on the drain groove 612, an embedding step 6120 is provided at the opening of the drain groove 612, and an embedding protrusion 650 is provided at the edge of the waterproof membrane 65. A stud is provided in the drain groove 612, and a screw hole is provided on the waterproof membrane 65. In this way, the waterproof membrane 65 is embedded in the embedding step 6120 through the embedding protrusion 650 and is embedded together with the drain groove 612, and is locked together with screws. A sealing gasket (not shown in the figure) is provided between the embedding protrusion 650 and the embedding step 6120.

[0034] like Figure 3 , 4 As shown, the water pipe 63 is positioned between the lower support 62 and the submersible pump 3, and between the lower support 62 and the upper support 61, with the outlet end of the water pipe 63 connected to the drain trough 612. A permeable hole 64 is also provided at the bottom of the lower positioning slide 621. In this way, water in the water tank 2 is pumped to the drain trough 612 by the submersible pump 3. After flowing through the permeable hole 64 into the humidifying filter 4, the water then flows into the water tank 2 through the permeable hole 64 in the lower positioning slide 621, thus circulating the water within the humidification device.

[0035] like Figure 6 , 7 As shown, the upper bracket 61 and lower bracket 62 are preferably square structures composed of two horizontal frame edges 610 and two vertical frame edges 620. The upper positioning groove 611 and the lower positioning groove 621 are provided on the vertical frame edge 620. In this way, an air filter channel 20 is formed between the upper and lower vertical frame edges 620, and a disassembly and assembly channel 10 is formed between the upper and lower horizontal frame edges 610. A water pipe connector is provided on the horizontal frame edge 610 located inside the housing 1 for connecting a water pipe 63. In this way, the bracket assembly 6 not only has high structural strength and is easy to assemble, but also allows humidifying filters 4 to be installed on both the left and right sides. At the same time, air filter assemblies 5 are also provided on the left and right sides of the housing 1, thereby achieving a better humidification and filtration effect.

[0036] like Figure 1As shown, the air filter assembly 5 of this utility model includes a filter support 51, an air filter 52, and an air inlet grille 53 fastened to the side wall of the housing 1, all fixedly installed inside the housing 1. The lower part of the filter support 51 is a solid plate structure, and the upper part is a grille structure. This ensures airflow into the humidification device while preventing water from splashing onto the air filter 52. The filter support 51 also has vertical strips to support the air filter 52 and separate it from the humidifying filter 4 by a certain distance, further preventing water from splashing onto the air filter 52. Sealing gaskets are also provided around the air filter 52 to prevent air from bypassing the air filter 52 and flowing into the humidification device. Studs are provided on both sides of the filter support 51, allowing it to be fixed to the housing 1 with screws. Fastening protrusions are provided at the upper and lower ends of the air inlet grille 53, and corresponding fastening recesses are provided on the housing 1 to match the fastening protrusions.

[0037] like Figure 1 , 2 As shown, the two opposite walls of the disassembly hole 11 are respectively provided with insertion holes 111 and fastening holes 112. The two ends of the airtight door 7 are respectively provided with insertion heads 71 ​​and fastening heads 72. The insertion head 71 is detachably inserted into the insertion hole 111, and the fastening head 72 is detachably fastened to the fastening hole 112. This allows the airtight door 7 to be opened very conveniently without tools, making operation very easy. Furthermore, a handle 73 is provided at the upper part of the airtight door 7. This allows the user to open the airtight door 7 by simply bending slightly without squatting, making it more convenient and easier to use. The handle 73 can be a concave structure, making the outer surface of the device very flat and saving space; or it can be a convex structure, making it easier to grip and facilitating maintenance.

[0038] like Figure 1 , 2 As shown, an annular retaining edge 12 is provided on the inner wall of the insertion hole 111 and the fastening hole 112, and the sealing gasket 110 is disposed on the annular retaining edge 12. Thus, after the airtight door 7 is fastened onto the disassembly hole 11, its edge is tightly fitted with the annular retaining edge 12, preventing unfiltered air from seeping into the water-lubricating device from the edge of the airtight door 7. To prevent the sealing gasket 110 from falling off when the airtight door 7 is opened, the sealing gasket 110 can be bonded to the annular retaining edge 12.

[0039] like Figure 7As shown, the humidifying filter 4 consists of a filter frame 41 and humidifying cotton 42 installed inside the filter frame 41. The top and bottom of the filter frame 41 are respectively provided with a plurality of grid holes 43. Each grid hole 43 consists of horizontal elongated holes 431 located on the top or bottom surface of the filter frame 41 and vertical elongated holes 432 located on the leeward side 44 of the filter frame 41, with the horizontal and vertical elongated holes 431 and 432 interconnected. In this way, moisture can permeate from the top of the filter frame 41 to the humidifying cotton 42 through the grid holes 43, and the moisture on the humidifying cotton 42 can also quickly drain from the bottom of the filter frame 41, thus ensuring smooth water flow. Furthermore, since the vertical elongated holes 432 are located on the leeward side 44 of the filter frame 41, it also prevents water from splashing onto the air filter assembly 5 when the water flow is large, thus affecting the normal operation of the air filter assembly 5. The water tank 2 is preferably an open structure, so that when the water flow is large, it can flow directly into the water tank 2 from the leeward side of the humidifying filter 4 to form a waterfall flow, thereby improving the humidification effect of the water humidification device. At the same time, it can also increase the water circulation rate, which is beneficial to inhibiting bacterial growth.

[0040] like Figure 4 , 5 As shown, a drainage cavity 23 is provided at the bottom of the side wall of the water tank 2 facing the disassembly hole 11. A drainage hole 231 communicating with the water tank 2 is opened on the top wall of the drainage cavity 23. A drainage pipe fitting 232 connected to the drainage hole 231 is hidden inside the drainage cavity 23, and a sealing gasket (not shown in the figure) is provided between the drainage pipe fitting 232 and the drainage hole 231. The drainage pipe fitting 232 is L-shaped, so that when humidification is not required, the residual water in the water tank 2 can be drained through the drainage pipe fitting 232, making the operation more convenient; and the drainage pipe fitting 232 is hidden in the drainage cavity 23, ensuring the neatness and flatness of the outer surface of the water tank 2.

[0041] like Figure 4 As shown, a water pump recess 25 is provided at the bottom of the water tank 2, and the submersible pump 3 is installed in the water pump recess 25. This ensures that the submersible pump 3 can work normally even when the water level in the water tank 2 is low, thereby improving the operational stability of the device and increasing the effective utilization rate of the water tank 2. A cover plate 26 is also placed at the opening of the water pump recess 25 to protect the submersible pump 3. The cover plate 26 is also provided with a water permeable strip hole 261 and a through hole 262 for the water outlet of the submersible pump 3 to pass through. The cover plate 26 is locked to the water pump recess 25 with screws.

[0042] like Figure 5 As shown, the bottom of the water tank 2 is provided with a threaded post 24, so that the water tank 2 can be fixed to the housing 1 with screws. This way, the water tank 2 will not shake during the movement of the water lubrication device, and the water inside the water tank 2 will not easily spill out.

[0043] like Figure 4 As shown, to further improve the hygienic performance of this invention, the water tank 2 is also equipped with an ultraviolet germicidal lamp 9 that can sterilize and disinfect the water. This ultraviolet germicidal lamp 9 is preferably an immersion-type ultraviolet germicidal lamp used for fish tank disinfection, which is directly inserted into the water tank 2 to sterilize the water. Alternatively, the ultraviolet germicidal lamp can be fixed inside the water tank 2 using a suction cup clip.

[0044] In addition, for ease of movement, such as Figure 2 As shown, a sliding wheel 16 is also installed on the bottom plate of the outer shell 1, so that the size of this utility model can be made very large, thus making it applicable to large spaces.

[0045] like Figure 1 , 2 As shown, the humidification device provided by this utility model is square in shape. Air enters the housing 1 from the left and right sides, passing through the air filter assembly 5 and the humidifying filter 4 in sequence, and then exits from the top of the humidification device, providing users with humidified and clean air, achieving the integrated effect of humidification and purification. Opening the sealed door 7 from the front of the housing 1 allows for easy removal and installation of the humidifying filter 4, and also enables the monitoring of the water level inside the water tank 2, allowing for timely replenishment of water.
