[0026] As attached Figure 1-10 As shown, this embodiment shows an air duct system of a mite removal instrument, comprising: a housing 1 and a dust cup 2, and the dust cup 2 is detachably arranged on the housing 1. The lower surface of the housing 1 is parallel to the plane to be cleaned.

[0027] A dust suction port 3 is provided at the bottom surface of the front end of the housing 1, a roller brush chamber 4 is provided at the bottom of the front end of the housing 1, a roller brush assembly 5 is provided in the roller brush chamber 4, and the dust suction port 3 is communicated with the roller brush chamber 4. A suction force generating chamber 6 is provided in the rear end of the housing 1. An air inlet pipe 38 and a dust outlet 7 are provided in sequence above the roller brush chamber 4, and an air inlet 8 is provided at the bottom of the dust cup 2, and the air inlet 8 is communicated with the dust outlet 7; a partition 9 is provided in the dust cup 2, a filter assembly 10 is provided on the partition 9, and a vent 11 is provided on the partition 9, and an air outlet 12 is provided at the bottom of the dust cup 2, and the air outlet 12 is communicated with the suction force generating chamber 6, and the air flow enters the dust cup 2 through the air inlet 8 and passes through the filter assembly 10, the vent 11 and the air outlet 12 in sequence to the suction force generating chamber 6.

[0028] The working principle of the mite removal device air duct system of this embodiment is as follows: the suction generating chamber 6 provides the suction required by the mite removal device. The mite removal device is placed on the object to be cleaned. Under the action of suction, the dust mites on the object to be cleaned enter the roller brush chamber 4 through the suction port 3 along with the airflow, and then pass through the roller brush assembly 5, through the air inlet pipe 38, the dust outlet 7 and the air inlet 8 to enter the dust cup 2. After entering the dust cup 2, the dust mites are screened out by the filter assembly 10 under the action of suction, and the clean air flow passes through the filter assembly 10, and then passes through the vent 11 and the air outlet 12 in turn to enter the suction generating chamber 6, and is finally discharged to the outside of the mite removal device.

[0029] The advantage of the dust mite removal device of this embodiment is that the airflow entering the dust mite removal device must be filtered by the filter assembly 10 before it can be discharged, preventing part of the air from being discharged outside the housing 1 without being filtered, thereby improving the performance of dust mite removal. At the same time, the dust mite removal device of this embodiment only needs to be provided with a dust outlet 7 above the front end of the housing 1, and only needs to be provided with an air inlet 8 at the bottom of the front end of the corresponding dust cup 2. Compared with the prior art, there is no need to provide another additional air outlet above the front end of the housing 1, nor is there a docking cavity for connecting the air outlet with the suction generating chamber, so that the size of the whole machine can be reduced and more compact.

[0030] Among them, a suction motor 13 is arranged in the suction generating chamber 6, a motor cover 39 is arranged at the output end of the suction motor 13, a connecting pipe 40 is arranged at the front end of the motor cover 39, the connecting pipe 40 is connected to the air outlet 12, and the casing 1 is respectively provided with heat dissipation mesh holes 14 on both sides of the suction motor 13.

[0031] It is understandable that the suction motor 13 provides the required suction force for the mite removal device. Under the action of the suction motor 13, the dust mites on the object to be cleaned enter the roller brush chamber 4 along with the airflow through the suction port 3, and then pass through the roller brush assembly 5 and enter the dust cup 2 through the dust outlet 7 and the air inlet 8. After entering the dust cup 2, the dust mites are screened out by the filter assembly 10 under the action of suction force, and the clean air flow passes through the filter assembly 10, and then passes through the vent 11 and the air outlet 12 in turn to enter the suction force generation chamber 6, and finally is discharged to the outside of the mite removal device through the heat dissipation mesh 14.

[0032] Among them, the dust cup 2 includes a top cover 15, a partition 9 and a cup body 16. The cup body 16 includes a cyclone chamber 17 and a dust collecting chamber 18 which are arranged in parallel and interconnected. The air inlet 8 is arranged on the cyclone chamber 17, the filter assembly 10 is located in the cyclone chamber 17, and the partition 9 is located between the top cover 15 and the cup body 16.

[0033] Among them, the angle between the dust cup 2 of this embodiment and the horizontal plane is 14°.

[0034] Specifically, under the action of suction, the dust mites on the object to be cleaned enter the roller brush chamber 4 along with the airflow through the dust suction port 3, and then pass through the roller brush assembly 5, through the dust outlet 7 and the air inlet 8, and enter the cyclone chamber 17 of the dust cup 2. After entering the cyclone chamber 17, the air carrying the dust mites rotates along the cyclone chamber 17 under the action of suction, and the dust with a larger mass rotates and enters the dust collecting chamber 18 under the action of centrifugal force, and the other part of the dust mites in the air are screened out by the filter assembly 10. The clean air flow passes through the filter assembly 10, and then passes through the vent 11 and the air outlet 12 in turn to enter the suction generating chamber 6, and is finally discharged to the outside of the mite removal device.

[0035] The present embodiment also provides a mite removal device, including the above-mentioned air duct system, and also includes a panel 19 arranged on the top cover 15, a spring 20 is arranged inside the panel 19, a latch 21 is arranged on the top cover 15 and the cup body 16, a protrusion 22 is arranged on the cup body 16, the middle part of the latch 21 is hinged to the panel 19, one end of the latch 21 is acted upon by the elastic force of the spring 20, and the other end is latched with the protrusion 22.

[0036] The present embodiment realizes the quick disassembly and assembly of the dust cup 2 top cover 15 and the cup body 16 through the above structure. When disassembling, press one end of the spring 20 provided on the latch 21 to disengage the other end of the latch 21 from the protrusion 22, and then the top cover 15 can be removed. When assembling, press the latch 21 in the same way to put the top cover 15 back.

[0037] Among them, a handle 23 is provided on the upper rear end of the casing 1, an insert block 24 is provided at the bottom of the front end of the dust cup 2, and a socket 25 is correspondingly provided at the top of the front end of the casing 1; a card slot 26 is provided at the rear end of the dust cup 2, and a buckle 27 is provided on the handle 23.

[0038] Specifically, a convex strip (not shown in the figure) is provided at the insertion hole 25, and the convex strip is used to prevent the dust cup 2 from sliding forward.

[0039] In this embodiment, the dust cup 2 and the housing 1 are assembled through the above structure, that is, the front end of the dust cup 2 is plugged into the housing 1, and the rear end of the dust cup 2 is snap-fitted into the handle 23.

[0040] Among them Figure 8 As shown, a driving motor 28 and a transmission assembly 29 are arranged inside the front end of the housing 1, and the driving motor 28 drives the roller brush assembly 5 to rotate through the transmission assembly 29. Specifically, the transmission assembly 29 includes gears connected to the driving motor 28 and the roller brush assembly 5 respectively, and the two gears are synchronously rotated through a synchronous belt, thereby achieving the purpose of driving the roller brush assembly 5 to rotate by the driving motor 28.

[0042] The working principle of the above components is as follows: when using the mite remover, place the mite remover on the surface of the object to be cleaned, and the dust sensor 30 can detect the amount of dust on the surface of the object. If there is a lot of dust, it will transmit a signal to the control panel 31, and the control panel 31 will control the dust mite warning light 33 on the display screen 32 to light up, so as to remind the user to clean the current area repeatedly. After the dust in the current area is reduced, the dust sensor 30 detects that the dust has been reduced, and then transmits a signal to the control panel 31, and the control panel 31 controls the dust mite warning light 33 on the display screen 32 to turn off, so as to remind the user that the current area has been cleaned.

[0043] In other embodiments, an ultrasonic generator 34 and an ultraviolet sterilization lamp 35 are also provided at the bottom of the front end of the housing 1 to assist the mite removal device in sterilization and improve the cleaning effect.
