Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to a vehicle-mounted air purifier. Background Art

[0002] During the mine operation, scrapers are used to transport the mined ore. Scrapers are usually diesel engines, which produce a lot of exhaust gas during driving. Exhaust gas is also easy to enter the cab, so it is necessary to install an air purifier in the cab.

[0003] For example, patent application number CN202321191877.4 discloses a vehicle-mounted air purification device, which drives the first limiting block 104 to disengage from the interior of the first limiting hole 105 by pulling the pull rod 103. At this time, the box door 101 can be opened, and the filter element 702 can be disassembled and replaced by the setting of the second slide groove 701. It is also convenient to clean the ultraviolet lamp 703. The setting of the first magnet 503 and the second magnet 504 is conducive to taking out the storage box 501 from the installation groove 402 by pulling the pull ring, which is convenient for replacing the freshener 502, and then the vehicle-mounted air purification device can be used. During use of the device, the effect of easy disassembly and maintenance is ensured. By setting the second limiting groove 303, the second spring 304, the second limiting block 305 and the second limiting hole 306, the air intake frame 301 can be opened along the hinge by pulling the pull ring on the top of the air intake frame 301. By setting the third limiting groove 601, the third spring 602, the third limiting block 603 and the third limiting hole 604, the exhaust frame 201 can be opened in the same way. By setting the exhaust port 2, the air inlet 3 and the fan 203, the rotation of the fan 203 is conducive to improving the air circulation efficiency inside the device, thereby improving the efficiency of air purification.

[0004] During use, the patent in the prior art can only filter and block the air and impurities, but lacks the function of treating harmful substances in the air. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a vehicle-mounted air purifier to solve the problem described in the background art that the cab of a mine scraper lacks effective air purification equipment.

[0009] A plurality of mounting plates are arranged at the bottom of the barrel;

[0010] The sleeve body has a port that is detachably connected to the open end of the barrel body;

[0011] Two filter components are respectively arranged in the sleeve body and the barrel body;

[0012] The filter assembly includes

[0013] An internal threaded sleeve, fixedly connected to the inner wall of the sleeve body or barrel body;

[0014] The second filter screen is conical, and the open end of the second filter screen is fixedly connected to a port of the internal thread sleeve;

[0015] The external threaded sleeve is connected to the internal threaded sleeve through threads;

[0016] The third filter screen is conical, and the open end of the third filter screen is fixedly connected to a port of the external threaded sleeve;

[0017] A plurality of retaining screens, all of which are annular, are fixedly connected to the second filter screen;

[0018] The baffle, the second filter and the third filter form a plurality of annular storage chambers.

[0019] Preferably, the storage chamber in the filter assembly in the sleeve body corresponds to the position of the baffle in the filter assembly in the barrel body.

[0020] Preferably, one end of the sleeve away from the barrel body is detachably connected to a cover body, and the cover body is provided with a first filter screen.

[0021] The beneficial effects of adopting the above technical solution are:

[0022] The present application places activated carbon in the storage chamber to purify and adsorb the air passing through the adjacent storage chamber, thereby achieving air purification and filtration. In the present application, the third filter can be separated from the second filter, so that the storage chamber can be opened, thereby achieving replacement of the activated carbon.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-4 In this embodiment, a vehicle-mounted air purifier includes

[0030] Barrel 10;

[0031] An air inlet pipe 21 is provided at the bottom of the barrel body 10 and communicates with the barrel body 10 , and a fan 20 is provided in the air inlet pipe 21 ;

[0032] A plurality of mounting plates 12 are provided at the bottom of the barrel 10;

[0033] The sleeve 11 has a port that is detachably connected to the open end of the barrel 10;

[0034] Two filter components are respectively arranged in the casing 11 and the barrel 10;

[0035] The filter assembly includes

[0036] The internal threaded sleeve 40 is fixedly connected to the inner wall of the sleeve body 11 or the barrel body 10;

[0037] The second filter screen 41 is conical, and the open end of the second filter screen 41 is fixedly connected to one end of the internal threaded sleeve 40;

[0038] The external threaded sleeve 50 is connected to the internal threaded sleeve 40 through threads;

[0039] The third filter screen 51 is conical, and the open end of the third filter screen 51 is fixedly connected to one end of the external threaded sleeve 50;

[0040] A plurality of retaining screens 42, all of which are annular, are fixedly connected to the second filter screen 41;

[0041] The blocking screen 42 , the second filter screen 41 , and the third filter screen 51 form a plurality of annular storage chambers 60 .

[0042] This embodiment is implemented as follows:

[0043] When the present application is in use, activated carbon is placed in the storage chamber 60 of the filter assembly in the casing 11, and the activated carbon is placed in the storage chamber 60 at intervals. Activated carbon is placed in the storage chamber 60 of the filter assembly in the barrel 10, and the activated carbon is also placed in the storage chamber 60 at intervals.

[0044] Connect the fan 20 to the power supply of the cab, and the fan 20 will draw out the air in the barrel body 10. At this time, air will enter the sleeve 11, and the air will pass through the third filter 51 into the storage chamber 60. The air will be adsorbed by the activated carbon in the adjacent storage chamber 60, and the filtering effect can be effectively improved by passing through two filter components. When the activated carbon needs to be replaced, separate the sleeve 11 from the barrel body 10, and then rotate the external threaded sleeve 50 to separate the external threaded sleeve 50 from the internal threaded sleeve 40, so that the third filter 51 is separated from the second filter 41, thereby replacing the activated carbon.

[0045] The advantage of the present application over the prior art is that it can effectively improve the air purification effect and facilitate the replacement of activated carbon.

[0046] See also Figure 2 , the storage chamber 60 in the filter assembly in the sleeve body 11 corresponds to the position of the baffle 42 in the filter assembly in the barrel body 10;

[0047] By staggering the positions of the storage chamber 60 in the sleeve body 11 and the storage chamber 60 in the barrel body 10, the air purification time can be extended.

[0048] See also Figure 1 、 2 The end of the sleeve 11 away from the barrel 10 is detachably connected to a cover 30, and the cover 30 has a first filter 31;

[0049] By arranging the first filter 31 on the cover body 30 , large particles of dust can be filtered, and the cover body 30 and the sleeve body 11 are connected by threads.

[0050] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, and these all fall within the scope of protection of the present invention.
