The present application is described in further detail below in conjunction with figures 1-13.

The embodiment of the application discloses an air purifier. Referring to fig. 1 and 2, an air cleaner includes a housing provided with an air inlet 1 and an air outlet 2. The filter module 3, the power supply module 4, the power module 5 and the processing module 6 are sequentially arranged in the shell along the air flowing direction.

Referring to fig. 2, in order to more uniformly purify the air in the vehicle, the housing includes an inner housing 7 and an outer housing 8 sleeved outside the inner housing 7. The inner housing 7 and the outer housing 8 are hollow cylinders. And when the air purifier is in a use state, the inner shell 7 and the outer shell 8 are both arranged along the vertical direction. The process module 6 is mounted on the upper end of the outer housing 8 and closes the upper end of the outer housing 8. The filtering module 3, the power supply module 4 and the power module 5 are sequentially arranged in the inner shell 7 from bottom to top. Meanwhile, a base 12 for closing the lower end of the inner shell 7 and the lower end of the outer shell 8 is fixedly arranged at the lower end of the outer shell 8.

Specifically, referring to fig. 1 and 3, a plurality of air guide ribs 9 are provided outside the outer casing 8, and the air guide ribs 9 are axially provided along the outer casing 8 and are circumferentially spaced apart along the outer casing 8. The air inlet 1 is arranged on the outer wall of the outer shell 8 and a plurality of air inlets are arranged along the circumference of the outer shell 8. Each air inlet 1 is located between two adjacent air guiding ribs 9. With reference to fig. 2, the air inlet 1 is communicated with the inner cavity of the outer shell 8. The upper end of the outer shell 8 is opened to form an air outlet 2.

Referring to fig. 2 and 4, the outer wall of the inner housing 7 is fixedly provided with a sealing collar 10 along its circumference. The outer wall of the inner shell 7 is provided with a convex rib 11 along the axial direction, and the convex rib 11 extends from the lower end surface of the sealing convex ring 10 to the lower end surface of the inner shell 7. Four ribs 11 are equally spaced circumferentially along the inner housing 7. When the inner shell 7 is embedded into the outer shell 8, the sealing convex ring 10 and the convex rib 11 are abutted against the inner wall of the outer shell 8 and are in interference fit with the outer shell 8. The sealing convex ring 10, two adjacent convex edges 11, the inner wall of the outer shell 8, the outer wall of the inner shell 7 and the base 12 enclose a closed diversion cavity 13. The side wall of the inner shell 7 is provided with an air guide opening 14, and the air guide opening 14 is communicated with the inner cavity of the inner shell 7. The air guide opening 14 is positioned at the lower end of the inner shell 7. The air guide openings 14 are circumferentially arranged along the inner shell 7, and one air guide opening 14 corresponds to one air guide cavity 13. The diversion cavity 13 is communicated with the air guide opening 14 and the air inlet 1.

Referring to fig. 2, the base 12 includes a first closing unit 15 embedded in the lower end of the outer case 8 and a second closing unit 16 fixedly coupled to the lower end of the inner case 7. Referring to fig. 5 and 6, the second closing unit 16 is a hollow cylinder with a seal provided at an upper end. The first sealing unit 15 is a ring and is fixedly sleeved outside the second sealing unit 16. The lower end surfaces of the first closing unit 15 and the second closing unit 16 are located on the same plane. Referring to fig. 2, when the first closing unit 15 is embedded in the outer case 8 and the second closing unit 16 is fixedly connected to the lower end of the inner case 7, both the lower end of the outer case 8 and the lower end of the inner case 7 are closed by the base 12.

When the air purifier is used, air enters the guide cavity 13 from the air inlets 1 around the outer shell 8, enters the air guide opening 14 under the guide of the guide cavity 13, and flows through the air guide opening 14 to enter the inner cavity of the inner shell 7. After passing through the filtering module 3, the power supply module 4, the power module 5 and the processing module 6 in sequence, the air enters the outer shell 8 from the opening at the upper end of the inner shell 7 and leaves from the air outlet 2 on the outer shell 8, thus finishing purification. In the process, the air purifier collects the air around the air purifier through the matching of the air inlet 1, the flow guide cavity 13 and the air guide opening 14, and the air purifier is not only subjected to single-point air inlet, so that the air around the air purifier can be collected and processed more uniformly.

Referring to fig. 5 and 6, in order to allow air to enter the inner cavity of the inner case 7 from the air guide opening 14, the air cleaner can be more stably placed on the placement plane. The upper end surface of the second closed unit 16 is recessed downwards to form an overflow groove 17, and the overflow groove 17 is arranged along the radial direction of the second closed unit 16. The overflow grooves 17 are circumferentially arranged along the second closed unit 16, and one overflow groove 17 corresponds to one air guide opening 14. When air enters the inner cavity of the inner shell 7 from the air guide opening 14, part of the air can escape into the overflow groove 17, so that part of the air flows upwards to cause the air purifier to receive upward force.

Referring to fig. 2 and 4, for more convenient replacement of the filter module 3, the inner housing 7 is separately provided as an upper housing 18 and a lower housing 19, and both the upper housing 18 and the lower housing 19 are hollow cylinders. The power module 4 and the power module 5 are mounted in the upper housing 18, and the filter module 3 is mounted in the lower housing 19.

Specifically, referring to fig. 2 and 4, the sealing convex ring 10 is disposed on the outer periphery of the upper housing 18, the inner wall of the outer housing 8 is provided with an annular supporting member 20, when the upper housing 18 is embedded into the outer housing 8, the sealing convex ring 10 and the outer housing 8 are in interference fit, and the sealing convex ring 10 abuts against the annular supporting member 20, so that the upper housing 18 is fixedly connected with the outer housing 8. The outer circumferences of the upper shell 18 and the lower shell 19 are provided with ribs 11. The rib 11 of the lower housing 19 is fixedly connected to the upper end surface of the first closing unit 15, so that the lower housing 19 is fixedly connected to the base 12. The air guide opening 14 is formed in the lower housing 19. Referring to fig. 2, the filter module 3 includes an activated carbon filter 21 and a HEPA filter 22, and the activated carbon filter 21 and the HEPA filter 22 are fixedly installed in the lower housing 19 in this order from bottom to top.

The air entering the inner cavity of the inner shell 7 from the air guide opening 14 is filtered by the active carbon filter element 21 and the HEPA filter element 22 to remove the impurity such as large particle dust, thus completing the purification. Because the filter module 3 is installed in the lower housing 19, and the lower housing 19 is fixedly connected to the base 12, when the filter module 3 needs to be replaced, the base 12 is directly pulled out of the outer housing 8, and the operation is convenient. The installation is also only needed to directly press the base 12 into the lower end of the outer shell 8. After the base 12 is in place, the lower housing 19 abuts the upper housing 18.

For better heat dissipation, referring to fig. 7, the power module 4 includes four battery units 26 and a mount 23. The mounting block 23 includes a mounting sleeve 24 and a connector 25. The battery cells 26 are circumferentially arranged along the upper case 18. The cross section of the mounting sleeve 24 is circular arc-shaped, and the mounting sleeve 24 is sleeved outside the battery unit 26. One mounting sleeve 24 corresponds to one battery unit 26 and the mounting sleeve 24 is fixedly connected to the inner wall of the upper housing 18. So that the battery unit 26 is fixedly mounted in the upper case 18 by the mounting sleeve 24. Four connecting pieces 25 are provided, and one connecting piece 25 is distributed between two adjacent mounting sleeves 24. The two ends of the connecting piece 25 are fixedly connected with the two corresponding adjacent mounting sleeves 24 respectively. The mounting sleeve 24 and the connecting piece 25 enclose a passage channel 27, the passage channel 27 being intended for air to flow through the power module 5.

The air passing through the filtering module 3 flows through the power supply module 4 through the passage channel 27, so that the air can take away heat from the battery unit 26 when flowing, and the power supply module 4 can dissipate heat better.

In order to improve the air purification rate of the purifier, the negative ion generator module 42 is arranged in the passage channel 27. After the air is filtered by the activated carbon filter element 21 and the HEPA filter element 22, the negative ions released by the negative ion generator module 42 can charge particles such as smoke dust, germs, spores and pollen in the air, and then the particles are further killed by the treatment module 6, so that the dual sterilization and purification effects are achieved. The negative ions can adhere to dust, so that the dust stays in the air purifier for a longer time, and the purification rate is further improved.

Referring to fig. 2, the power module 5 includes a fan unit. The fan unit provides power to the air for driving the air from the air inlet 1 to the air outlet 2.

Referring to fig. 8, the process module 6 includes, in order from bottom to top, a titanium dioxide board 28, an LED lamp panel 29, a circuit board 30, and a top cover 31.

The battery unit 26 supplies power to the LED lamp panel 29 and the circuit board 30 through electric wires.

When the air purifier works, air passing through the power module 5 enters the processing module 6 for secondary purification. The UVA and UVC emitted by the LED lamp panel 29 destroy and change the DNA structure of microorganisms, so that bacteria die or can not reproduce offspring immediately, and the aim of sterilization is fulfilled. The titanium dioxide plate 28 generates photocatalytic reaction similar to photosynthesis under the irradiation of light, generates carboxyl free radicals and anion free radicals with strong oxidizing ability, can effectively decompose various organic compounds, can destroy bacterial cell membranes and viral proteins, and can remove organic pollutants. Thereby improving the purification degree of the air and leading the air to be purified to an ideal state as much as possible.

Specifically, referring to fig. 8 and 9, a connecting seat 32 is fixedly installed in the upper housing 18, and a first connecting groove 33 for embedding the titania plate 28 is formed in an upper end surface of the connecting seat 32. The bottom surface of the first connecting groove 33 is provided with a second connecting groove 34 for embedding the fan unit, and the second connecting groove 34 is communicated with the lower end surface of the connecting seat 32. The fan unit is embedded in the second connecting groove 34 and is abutted against the upper end surface of the mounting seat 23, so that the fan unit is stably mounted in the upper shell 18. The titanium dioxide plate 28 is embedded in the first connecting groove 33 and abuts against the inner wall of the first connecting groove 33, so that the titanium dioxide plate 28 is stably installed in the upper shell 18.

The LED lamp panel 29 is abutted against the first mounting post 35, and the first mounting protrusion 36 is embedded in the first caulking groove 37. By the above structure, the LED lamp panel 29 is stably mounted above the upper case 18.

Referring to fig. 11 and 12, the outer wall of the top cover 31 is provided with mounting projections 38, and the mounting projections 38 are provided in plurality along the circumferential direction of the top cover 31. When the top cover 31 is embedded in the upper end of the outer shell 8, the mounting protruding block 38 abuts against the outer wall of the outer shell 8 and is in interference fit with the outer shell 8. So that the top cover 31 is fixedly mounted to the outer housing 8. The gaps between the mounting bosses 38 allow for the removal of two purified air streams.
