The first embodiment is as follows:
referring to fig. 1-2, a domestic air purifier with a recyclable filter element comprises a base 1, an air exhaust groove 2 is formed in the side wall of the base 1, an air exhaust fan 3 is mounted on the inner wall of the air exhaust groove 2, and the mounting mode of the air exhaust fan 3 is the existing mature technical means and is not described herein in detail.
The air inlet 21 that communicates with the groove of bleeding 2 is seted up to the lateral wall of base 1, has seted up exhaust duct 4 on the lateral wall of base 1, and sliding connection has the arc slider 31 with exhaust duct 4 complex in the groove of bleeding 2, and it should be noted that, arc slider 31 slightly is greater than exhaust duct 4, and the inner wall in arc slider 31 and the groove of bleeding 2 closely laminates, so can guarantee that when arc slider 31 blocks up exhaust duct 4, the gas tightness is good between the two.
And arc slider 31 fixed connection has been seted up filter tank 6 on one of them flabellum of extraction fan 3 on the lateral wall of base 1, is equipped with filter core 8 in the filter tank 6, and the embedded rubber tube 7 that is equipped with a plurality of elasticity of filter core 8, and a plurality of gas pockets 71 have been seted up to the lateral wall of rubber tube 7, and rubber tube 7 passes through air duct 5 and exhaust duct 4 intercommunication. A detachable sealing plate with good air tightness is arranged on part of the side wall of the base 1 near the filter tank 6 so as to conveniently replace the filter element 8 in the filter tank 6.
The dust storage groove 9 that communicates with the filter-tank 6 is seted up to the lateral wall of base 1, and glass layer 91 has been laid to the interior bottom in dust storage groove 9, and sliding connection has sliding plug 10 in dust storage groove 9, and sliding plug 10's lateral wall is equipped with silk 101, and sliding plug 10 passes through spring 11 elastic connection on dust storage groove 9's inner wall, and the embedded outlet duct 12 that communicates with dust storage groove 9 that is equipped with of base 1. Specifically, as shown in fig. 1, the silk 101 is located on a part of the side wall of the sliding plug 10, and this design can ensure that: when the sliding plug 10 moves back and forth in the dust storage groove 9, the silk on the side wall of the sliding plug 10 can rub the glass layer 91 to generate static electricity, and meanwhile, the sliding plug 10 and the glass layer 91 have good air tightness.
When the device works, the air exhaust fan 3 operates to suck in the outside air from the air inlet 21 and then exhaust the outside air from the exhaust groove 4, and the air exhausted from the exhaust groove 4 is exhausted into the rubber tube 7 from the air guide tube 5.
Simultaneously when the extraction fan 3 in operation, the arc slider 31 on one of them flabellum also constantly slides along the inner wall of air exhaust groove 2, and just can block up air exhaust groove 4 when arc slider 31 is just right to the time with air exhaust groove 4, and the air can't be discharged this moment, leaves the back when arc slider 31, and the air just can be discharged through air exhaust groove 4. Therefore, the air discharged from the air discharge duct 4 is intermittently discharged into the rubber hose 7 at a certain interval.
When air is suddenly discharged into the rubber tube 7, the air pressure in the rubber tube 7 is increased instantly, the elastic rubber tube 7 is expanded, and when the air is in the exhaust interval, the elastic rubber tube 7 is recovered. The rubber tube 7 will be continuously bulged and recovered by the circulation. And because the rotation speed of the air exhaust fan 3 is very fast when air exhaust, the exhaust interval time of the exhaust groove 4 is very short, therefore, the rubber tube 7 is continuously bulged and the recovery frequency is very high, the filter element 8 wrapped on the outer wall of the rubber tube 7 can be continuously shaken, larger dust and other particles adsorbed on the filter element 8 can be shaken off, the filtering performance of the filter element 8 after use is improved, and the filter element 8 can be recycled.
The air discharged by the rubber tube 7 enters the dust storage groove 9 and pushes the sliding plug 10 to move right, and when the air is at an exhaust interval, the spring 11 pushes the sliding plug 10 to move left, so that the sliding plug 10 can move back and forth, the silk 101 on the side wall of the sliding plug 10 continuously rubs with the glass layer 91 in the dust storage groove 9, static electricity is generated on the surface of the glass layer 91, dust and other fine particles shaken off from the filter element 8 can be adsorbed, and secondary pollution caused by the fact that the shaken off dust and other particles are discharged into a room along with air flow is avoided.
Example two:
referring to fig. 3-4, different from the first embodiment, the side wall of the base 1 is provided with a liquid storage tank 13, the air outlet pipe 12 extends into the liquid storage tank 13, and a part of the side wall of the air outlet pipe 12 located in the liquid storage tank 13 is provided with a plurality of capillary holes 121. The side wall of the base 1 is provided with a water filling port 131 communicated with the liquid storage tank 13.
In this embodiment, in hot weather or dry air, a proper amount of clean water can be added into the reservoir 13 through the water injection port 131.
When no air flows in the air outlet pipe 12, the water in the liquid storage tank 13 cannot flow into the air outlet pipe 12 through the capillary holes 121 under the action of the surface tension of the water because the pore diameter of the capillary holes 121 is extremely small; when the air discharged at high speed is sprayed out of the air outlet pipe 12, the gas in the air outlet pipe 12 has high flow speed and low pressure intensity, the water outside the air outlet pipe 12 hardly flows and has high pressure intensity, pressure difference is formed between the inside and the outside of the air outlet pipe 12, the water in the liquid storage tank 13 can be squeezed into the air outlet pipe 12 through the capillary holes 121, the water flowing in through the capillary holes 121 is in a liquid drop shape and is sprayed out of the air outlet pipe 12 along with the air flow to finally form water mist, the humidity of the indoor air can be rapidly increased, or the indoor temperature is reduced in hot weather, so that the indoor air quality is improved.
It is worth mentioning that, on one hand, the dust or other particles shaken off from the filter element 8 may not be completely adsorbed on the surface of the glass layer 91, and a small portion of the dust is discharged outwards along with the airflow, at this time, the water mist sprayed from the air outlet pipe 12 is sufficiently combined with the dust or other particles to form condensation nuclei to fall to the ground, so as to further prevent secondary pollution; on the other hand, the water mist sprayed out of the air outlet pipe 12 can be fully combined with various dust in the air, and the air can be dedusted, so that the air pumped into the device can be cleaner, the dust amount attached to the filter element 8 can be greatly reduced, and the structure of the implementation has a good improvement effect on the device.
Furthermore, mosquito repellent liquid can be added into the liquid storage tank 13, so that the device also has the function of repelling mosquitoes, or other air quality improving liquids such as air fresheners are added to improve the function of the device.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
