In a study on disease risk assessment, kitchen air pollution (smoke) has been listed as the greatest health risk after hypertension, smoking and alcohol abuse. More deaths occur each year from the continuous inhalation of smoke generated by kitchen fires than the total number of deaths due to malaria, tuberculosis and aids. The impact of kitchen air pollution on human health has also been documented in connection with farmer research. Scientists have investigated millions of farmers and found that farmers without ventilation on their home range have about twice the probability of lung cancer as do those farmers who build a chimney or ventilation at home. Researchers have shown that to the extent that lung cancer is a result, stoves without ventilation are used as much as smoking. The air purifier is applied to the fields of home, medical treatment and industry, and the home field takes a single-machine type household air purifier as a mainstream product in the market.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a portable air purifier, includes first barrel 1, and the one end sliding connection of first barrel 1 has second barrel 2, and first barrel 1 cup joints in the inboard of second barrel 2, as a whole exhaust duct. Meanwhile, the sliding connection of the first cylinder 1 and the second cylinder 2 enables the whole exhaust pipeline to stretch. One side that first barrel 1 was kept away from to second barrel 2 is rotated and is connected with first rotation axis 3, one side fixedly connected with support 4 of first rotation axis 3, support 4 can use first rotation axis 3 to rotate as the center, thereby can realize folding when needs are carried, the bottom fixedly connected with fan 5 of support 4, the bottom fixedly connected with connecting plate 6 of fan 5, the bottom of connecting plate 6 is equipped with extension board 7, one side threaded connection of extension board 7 has screw 10, extension board 7 and connecting plate 6 threaded connection are run through to the one end of screw 10, when using fan 5, support 4 is rotatory to the exit of second barrel 2 under the drive of first rotation axis 3. In order to avoid that the fan 5 generates certain vibration during actual operation, the support plate 7 and the connecting plate 6 are fixed into a whole through the screws 10. Because fan 5 and connecting plate 6 fixed connection, consequently connecting plate 6 and support 4 are fixed fan 5 from both sides respectively, have strengthened the fastness of fan 5 when the operation greatly. The bottom of the support plate 7 is fixedly connected with a second rotating shaft 11, and one side of the second rotating shaft 11 is rotatably connected with the second cylinder 2. When the portable bicycle is needed to be carried, the support plate 7 can be rotated and folded through the second rotating shaft 11, so that the portable bicycle is convenient to store. The inner walls of the first barrel 1 and the second barrel 2 are fixedly connected with a fixing plate 9, the bottom of the fixing plate 9 is fixedly connected with a third spring 23, the bottom of the third spring 23 is fixedly connected with a clamping block 8, and one side of the clamping block 8 is fixedly connected with a second spring 22. When the projection 21 is inserted down into the mounting groove, the clamping block 8 is pressed. Under the action of the second spring 22 and the third spring 23, the clamping block 8 enters the groove part of the projection 21 after moving, so that the projection 21 is clamped, and the filter device such as the filter screen 20 is connected with the first cylinder 1 or the second cylinder 2 in a buckling manner.

In this embodiment, specifically: one side fixedly connected with baffle 24 of second barrel 2, the bottom fixedly connected with first spring 12 of baffle 24, the outside of first spring 12 is equipped with sleeve pipe 13, and the one end fixedly connected with bottom plate 14 of baffle 24 is kept away from to first spring 12. The main function of the first spring 12 is to absorb the shock of the whole pipe, so as to avoid unnecessary loss caused by bumping during moving. The main function of the sleeve 13 is to prevent the position of the first spring 12 from being excessively offset.

In this embodiment, specifically: the bottom of the sleeve 13 is fixedly connected with a bottom plate 14, and the bottom of the bottom plate 14 is rotatably connected with a rotating shaft 15. The axle 15 is capable of multidirectional rotation so that the wheel 16 can be moved in any direction.

In this embodiment, specifically: the bottom of the rotating shaft 15 is fixedly connected with a wheel 16, and one end of the first cylinder 1 is provided with an air inlet 17. When the fan 5 is activated, air enters the duct from the air inlet 17.

In this embodiment, specifically: the inner cavity of the first cylinder 1 is connected with an air filter element 18 in a buckling mode, and one side, far away from the air filter element 18, of the inner cavity of the first cylinder 1 is connected with an active carbon purification plate 19 in a buckling mode. The inside of the activated carbon purification plate 19 is provided with fine holes, so that dust impurities in the air can be adsorbed under the condition of keeping the air circulation.

In this embodiment, specifically: the inner cavity buckle of second barrel 2 is connected with filter screen 20, and the equal fixedly connected with lug 21 in top and the bottom of filter screen 20. The projection 21 can be inserted into a slot of the second cylinder 2, thereby realizing a snap connection.

The working principle or the structural principle is that when the device is used, the first cylinder body 1 is pulled, so that the first cylinder body 1 slides on the inner side of the second cylinder body 2. After the stretching is finished, the filter screen 20, the activated carbon purification plate 19 and the air filter element 18 are fixed in the inner cavities of the first cylinder 1 and the second cylinder 2 in a buckling connection mode. The concrete mode of buckle connection does: the projection 21 is inserted into the groove of the inner wall of the first cylinder 1 and the second cylinder 2, and the clamping block 8 starts to contract under the action of the second spring 22 after being pressed by the projection 21. Meanwhile, the third spring 23 limits the clamping block 8. When the bent end of the clamping block 8 slides into the grooves on both sides of the projection 21, the clamping block 8 can clamp the projection 21 under the action of the second spring 22. At this time, the first rotating shaft 3 is rotated to turn off the output of the fan 5 toward the inner cavity of the second cylinder 2. The fan 5 and the support plate 7 are fixed together by screws 10. The fan 5 is started, and air enters from the air inlet 17 and is discharged to the back of the fan 5 after being filtered by three layers. Because the baffle plate 24 is fixedly connected with the second cylinder 2, when the device needs to be subjected to position transfer, the second cylinder 2 or the first cylinder 1 is pushed. The first cylinder 1 or the second cylinder 2 drives the baffle 24 to start moving. The baffle plate 24 moves the bottom plate 14 through the sleeve 13 and the first spring 12. The rotation shaft 15 is also rotated according to the direction of the manual pushing, so that the wheels 16 can be rolled according to the direction of the manual pushing.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
