Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, and in particular relates to a household composite air purifier. Background Technology

[0002] Air purifiers, also known as air cleaners, air fresheners, or air purifiers, are products that can adsorb, decompose, or transform various air pollutants (generally including PM2.5, dust, pollen, odors, formaldehyde and other decoration pollution, bacteria, allergens, etc.) to effectively improve air cleanliness.

[0003] For example, Chinese patent CN206207582U discloses an air purifier. This air purifier includes a flat outer shell with two opposing end faces and a side connecting the end faces. Two centrifugal fans are installed inside the shell, facing back-to-back, with their air inlets facing the end faces. Air inlets corresponding to the air inlets of the two centrifugal fans are provided on each end face, and filter components are installed at the air inlets. Air outlets corresponding to the air outlets of the two centrifugal fans are provided on the side of the shell.

[0004] This technical solution uses two centrifugal fans to form two air purification systems, enabling one air purifier to achieve the purification effect of two air purifiers, greatly improving the purification efficiency and further expanding the working coverage of this utility model air purifier. However, in this application, the filter component is always located at the air inlet, and the filtered pollutants adhere to the surface of the filter component. New air entering through the filter component still needs to pass through the pollutants and be contaminated again. At the same time, the pollutants adhering to the filter component reduce the air intake volume. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a household composite air purifier that achieves filtration while preventing pollutants from accumulating on the surface of the filter components.

[0006] In view of this, the present invention provides a household composite air purifier, including a water tank, a collection cover fixedly installed on the top of the water tank, an air inlet hood and an exhaust hood respectively provided on both sides of the water tank, the air inlet hood penetrating through the collection cover and extending to below the liquid level, the exhaust hood being connected to and communicating with the collection cover, a fan being provided inside the air inlet hood and the exhaust hood, a sleeve being connected to and communicating through the middle of the exhaust hood, and a moisture-absorbing layer being provided inside the sleeve.

[0007] Based on the above structure, the water tank is equipped with a partition, a filter is installed on one side of the partition, one end of the filter is connected to and passes through the other side of the partition, and a circulation pump is connected to and passes through the other end of the filter. The outlet end of the circulation pump is connected to and passes through the other side of the partition.

[0008] Based on the above structure, the filter includes a housing, one end of which extends to the outside of the water tank. A filter layer is slidably connected inside the housing, and a baffle block is slidably connected inside the housing. The baffle block and the inner wall of the housing are fixedly connected by a return spring. An end cap is threadedly connected to the end of the housing located outside the water tank. An inlet pipe is connected and passes through the housing below the filter layer. The inlet pipe is connected and passes through the other side of the partition. An outlet pipe is connected and passes through the housing above the filter layer. The outlet pipe is connected and passes through the circulation pump.

[0009] Based on the above structure, the sleeve is movably connected to a drawer with an open bottom. Multiple drawers are distributed equidistantly from top to bottom. The moisture-absorbing layer is placed inside the drawer, and the lower drawer contains the activated carbon layer and the aromatherapy layer in sequence.

[0010] Based on the above structure, the side wall of the water tank is threaded with an inlet sealing plug and an outlet sealing plug. The inlet sealing plug is located above the bottom of the air inlet cover, and the outlet sealing plug is located at the bottom of the water tank.

[0011] Based on the above structure, the water tank contains an ultraviolet disinfection lamp, which is located above the water level in the tank.

[0012] The beneficial effects of this utility model are:

[0013] 1. This type of household composite air purifier features two fans. The fan in the air intake hood compresses air into the water tank, where it is filtered to remove dust and impurities before overflowing. An ultraviolet disinfection lamp further disinfects both the air and water. The fan in the exhaust hood draws air out of the water tank. During this exhaust process, the air absorbs water through a moisture-absorbing layer, then odors through an activated carbon layer, and finally, a fragrance layer adds a pleasant scent. This design ensures that dust and impurities remain in the water within the tank, preventing them from accumulating on the filter surface and affecting airflow.

[0014] 2. This type of household composite air purifier has a water tank equipped with a filter and a circulation pump. The circulation pump can draw water out of the water tank and circulate it, filtering it through the filter during the circulation process. This allows some impurities to be filtered out, thereby increasing the water change interval. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0023] This application discloses a household composite air purifier, including a water tank 1. A collection cover 2 is fixedly installed on the top of the water tank 1. An air inlet hood 3 and an exhaust hood 4 are respectively provided on both sides of the water tank 1. The air inlet hood 3 penetrates the collection cover 2 and extends to below the liquid level. The exhaust hood 4 is connected to and passes through the collection cover 2. A fan 5 is provided inside the air inlet hood 3 and the exhaust hood 4. A sleeve 6 is connected to and passes through the middle of the exhaust hood 4. A moisture-absorbing layer 7 is provided inside the sleeve 6.

[0024] Based on the above structure

[0025] In one embodiment, a partition 9 is provided inside the water tank 1. A filter 10 is provided on one side of the partition 9. One end of the filter 10 is connected to and passes through the other side of the partition 9, and the other end of the filter 10 is connected to and passes through a circulation pump 11. The outlet end of the circulation pump 11 is connected to and passes through the other side of the partition 9. Specifically, by setting the partition 9, the filter 10 and the circulation pump 11 are separated to the outside of the water, and the water is circulated and filtered on the outside.

[0026] In this embodiment, by setting up a filter 10 and a circulation pump 11, the circulation pump 11 can draw water from the other side of the partition 9, filter it through the filter 10, and then return it to the other side of the partition 9, thereby filtering out dust and impurities in the water.

[0027] Based on the above structure

[0028] In one embodiment, the filter 10 includes a housing 101, one end of which extends to the outside of the water tank 1. A filter layer 102 is slidably connected inside the housing 101. A blocking block 103 is slidably connected inside the housing 101. The blocking block 103 and the inner wall of the housing 101 are fixedly connected by a return spring 104. An end cap 105 is threadedly connected to the end of the housing 101 located outside the water tank 1. An inlet pipe 106 is connected and passes through the housing 101 below the filter layer 102. The inlet pipe 106 is connected and passes through the other side of the partition 9. An outlet pipe 107 is connected and passes through the housing 101 above the filter layer 102. The outlet pipe 107 is connected and passes through the circulation pump 11. Specifically, the filter layer 102 is inserted to perform the filtering function, and the blocking block 103 is used to block the water passage. By inserting the filter layer 102 and tightening the end cap 105, the inlet pipe 106 and outlet pipe 107 can be filtered through the filter layer 102.

[0029] In this embodiment, when the filter layer 102 needs to be replaced, the filter layer 102 is pulled out from the outer shell 101. Under the action of the return spring 104, the blocking block 103 can move between the inlet pipe 106 and the outlet pipe 107 to block the circulation of water and prevent water leakage.

[0030] The sleeve 6 is internally connected to a drawer 12 with an open bottom. Multiple drawers 12 are evenly distributed from top to bottom. A moisture-absorbing layer 7 is placed inside the drawer 12, and the lower drawer 12 contains an activated carbon layer 16 and an aromatherapy layer 13. Specifically, the activated carbon acts as an adsorbent and filter, while the aromatherapy layer 13 adjusts the odor of the air. Because the aromatherapy layer 13 is positioned below the activated carbon layer 16, and the gas passes through the activated carbon layer 16 first and then through the aromatherapy layer 13, the influence of the aromatherapy layer 13 on the activated carbon layer 16 is reduced.

[0031] In this embodiment, the drawer 12 facilitates the replacement of multiple layers of materials.

[0032] The side wall of water tank 1 is threaded with an inlet sealing plug 14 and an outlet sealing plug 15. The inlet sealing plug 14 is located above the bottom of the air intake shroud 3, and the outlet sealing plug 15 is located at the bottom of water tank 1. Specifically, opening the inlet sealing plug 14 allows water to be added, and opening the outlet sealing plug 15 allows water to be drained. By restricting the position of the inlet sealing plug 14, it is ensured that when water overflows from the inlet, the liquid level in water tank 1 is above the bottom of the air intake shroud 3.

[0033] In this embodiment, the water tank 1 can be replenished and drained by setting the inlet sealing plug 14 and the outlet sealing plug 15.

[0034] The water tank 1 contains an ultraviolet (UV) disinfection lamp 8, which is located above the liquid level in the water tank 1. Specifically, the UV disinfection lamp 8, positioned above the liquid level, can disinfect both the air and the water inside the water tank 1.

[0035] In this embodiment, the ultraviolet disinfection lamp 8 can disinfect the water and air passing through the water tank 1.

[0036] In this embodiment, a household composite air purifier is used by turning on two fans 5. The fan 5 inside the air intake hood 3 compresses air into the water tank 1, filters dust and impurities in the water, and then overflows. The air and water are disinfected by an ultraviolet disinfection lamp 8. The fan 5 inside the exhaust hood 4 can draw air out of the water tank 1. During the exhaust process, the air in the water tank 1 will absorb water through the moisture-absorbing layer 7, then absorb odors through the activated carbon layer 16, and finally add a favorite scent through the fragrance layer 13. This allows dust and impurities in the air to remain in the water in the water tank 1, thus avoiding the problem of impurities accumulating on the surface of the filter components and affecting the airflow.

[0037] The water tank 1 is equipped with a filter 10 and a circulation pump 11. The circulation pump 11 can draw water out of the water tank 1 and circulate it. During the circulation process, the water is filtered by the filter 10, which can filter out some impurities and increase the water change interval.
