Description
Technical Field
The utility model relates to a mounting structure of a dust cup, and also relates to a dust suction device with the dust cup structure.
Background
At present, dust collectors are mostly divided into two types, one type is an older dust collector with a power line connection, and the dust collector has the advantages of high power, large suction force, unlimited duration and the like. But also has the corresponding disadvantages that the power cord is convenient to use from time to time due to the fact that the power cord is arranged, and the length and the flexibility of the power cord are limited. The other hand-held vacuum cleaner with the battery, which is popular in recent years, has small volume, is internally provided with the battery, does not need to be connected with an electric wire when in use, and is particularly convenient and flexible. The defect that the battery duration is limited by the weight and the volume of the whole machine, the number of the batteries is limited, so that the duration is limited to a certain extent, and meanwhile, in order to achieve a good suction effect, the power of an internal motor needs to be increased to improve the suction, so that the shortening of the duration of the batteries is aggravated.
In summary, in order to obtain better dust collection and endurance, the design requirements of the handheld dust collector are higher, and especially, the air duct design and the dust separation structure of the dust collector need to achieve better dust collection effect under the condition of the same or lower motor power.
When present hand-held type dust catcher's one-level filter screen filters, because wind channel and structural reason, do not have the dust space of depositing alone, the wind that mixes there is the dust foreign matter directly strikes the filter screen surface, and the filter screen surface can increase along with the dust like this, piles up at the filter screen surface and blocks up, blocks up the back, and the machine is unable normal use basically, and suction straight line reduces, and the noise improves. Such dust collection amount is limited. The dust separation effect is insufficient, so that more dust can be accumulated on the surface of the sea handkerchief after filtration, and the sea handkerchief is blocked. Resulting in the need for frequent cleaning of the machine and more filtered hpa. It can be seen that the existing handheld dust collector only has simple one-stage separation for separating dust passing through the filter screen, and has poor effect, so that the rear HEPA (filter element) is often easy to block, needs to be cleaned and is easy to damage.
At present, after the handheld dust collector finishes working, dust in the dust cup must be poured off to use next time, and if the design of the internal air channel is too complex, the dust in the dust cup is not convenient to treat in the future, so that a user can feel bad.

Detailed Description
The utility model is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, 2, 3 and 4, the vacuum cleaner in this embodiment includes a main body 1, a lining shell 2, a cyclone separator 3, a filter screen 4, a collecting cover 5, a hypa 6 and a motor 7, wherein the main body 1 has an air duct and an inner cavity 15, a lateral air inlet 11 is formed at the front end of the air duct, and an exhaust port 12 is formed at the rear end of the air duct; the tail end of the machine body 1 is provided with a handle 13 for holding a hand.
The lining shell 2 is provided with a filter cartridge 22 and a first-stage dust cup 21 positioned on one side of the filter cartridge 22, the side wall of the filter cartridge 22 is provided with a high-level tangential air inlet 24 and a low-level first-stage dust collecting port 25, and the first-stage dust collecting port 25 is introduced into the first-stage dust cup 21; the tail end of the lining shell 2 is provided with a sleeve part 23, and the HEPA 6 is arranged in the sleeve part 23.
The cyclone separator 3 is axially arranged in the middle of the filter cartridge 22, the cyclone separator 3 is provided with a cyclone air inlet 31 and an air outlet 32, and the bottom of the cyclone separator 3 forms a dust collecting chamber 33. The filter screen 4 is arranged at the periphery of the cyclone air inlet 31, and an annular cavity between the filter screen 4 and the inner wall of the filter cylinder 22 forms a primary centrifugal area 26.
The collecting cover 5 is arranged at the bottom of the lining shell 2 in an opening and closing way, the collecting cover 5 comprises a first bearing part 51, a second bearing part 52 and a third bearing part 53, the first bearing part 51 is positioned at one side of the second bearing part 52, the second bearing part 52 is annular, the third bearing part 53 is positioned at the center of the second bearing part 52, the first bearing part 51 forms the bottom of the primary dust cup 21, the second bearing part 52 forms the bottom of the primary centrifugal area 26 and the third bearing part 53 forms the bottom of the dust collecting chamber 33 under the closed state of the collecting cover 5.

The bottom end of the lining shell 2 is provided with a sealing ring 29, and the sealing ring 29 is in sealing contact with the edge of the collecting cover 5 when the collecting cover 5 is covered.
The working principle is as follows: the mixed air mixed with dust enters the machine air duct through the lateral air inlet 11 under the action of the negative pressure suction force of the motor 7, the dust density is higher than that of the air in the primary centrifugal area 26, so that the dust with larger weight rotates along the outer wall of the filter cylinder 22 under the action of inertia and centrifugal force, and is thrown out of the primary centrifugal area 26 through the primary dust collecting port 25 and enters the primary dust cup 21; the mixed air passing through the first-stage centrifugal area 26 continuously passes through the filter screen 4 and enters the filter screen 4, and part of dust which cannot pass through the filter screen 4 continuously rotates and is centrifugally separated again after rotating until being thrown out of the first-stage centrifugal area 26. The mixed air entering the interior of the filter screen 4, influenced by the rotational inertia of the primary centrifugal zone 26, continues to rotate to converge towards the centre and is further directed into the cyclone 3 through the tangential inlet 31 of the cyclone. The dust is thrown into the dust collecting chamber 33 under the action of centrifugal force, other air continuously enters the HEPA 6 through the air outlet 32, and the clean air is continuously sucked into the motor and finally discharged from the exhaust port 12 after the air is filtered by the high-density HEPA.
As shown in fig. 5, after the collecting cover 5 is opened, the three regions are separated, and the separated dust is poured out together, which is convenient.
