[0035] In the technical solution, the comb tooth scraping strip 4 is arranged on the air duct inner wall surface of the suction inlet air duct 2, so that the bed sheet is prevented from being scraped and wound around the roll brush assembly by continuously contacting the brush 31, the smoothness of the dust collector during use is ensured, the use experience is good, and the problem that the roll brush assembly stops rotating and is difficult to push and pull due to the winding of the bed sheet on the roll brush assembly during the beating process of the roll brush of the dust mite removing instrument in the prior art is effectively overcome.

[0036] In some embodiments, the comb tooth scraping strip 4 is a hard injection molding part, and the aforementioned hard injection molding part can be hard rubber, hard plastic, a metal part with high rigidity, etc.

[0037] In the technical solution, the comb tooth scraping strip 4 is integrally formed by using a hard injection molding part, which reduces the manufacturing difficulty of the part.

[0038] In some embodiments, the air duct inner wall surface of the suction inlet air duct 2 is formed with an assembly groove 21, and the connecting end 411 of the connecting strip 41 is detachably assembled in the assembly groove 21.

[0039] In the technical solution, the comb tooth scraping strip 4 is detachably assembled in the aforementioned assembly groove 21, so that the comb tooth scraping strip 4 can be detached from the air duct inner wall surface of the suction inlet air duct 2 for necessary cleaning when hair is wound on the comb tooth scraping strip 4, which is simple and convenient, and prevents the phenomenon of reduced dust collection performance caused by the too small suction flow port due to the winding of hair.

[0040] In some embodiments, the assembly groove 21 extends along the direction of the rolling central axis of the rolling brush assembly 3 and penetrates to one end face of the suction inlet channel 2, the length direction of the connecting strip 41 is parallel to the rolling central axis, and the connecting end 411 is connected to the assembly groove 21 in sliding connection along the length direction.

[0041] In the technical solution, the assembly groove 21 is designed to penetrate to one end face of the suction inlet channel 2, and the comb tooth scraping strip 4 is connected to the assembly groove 21 in sliding connection, so that the disassembly operation is very simple and convenient, the assembly direction can be indicated by the arrow in Figure 6 , and the disassembly operation is performed in the reverse direction.

[0042] Referring to Figure 2 , in some embodiments, the side groove wall of the assembly groove 21 away from the rolling brush assembly 3 has a support protruding strip 211 extending towards the outside of the assembly groove 21, and the connecting strip 41 further comprises a support bottom surface 412 abutting the top surface of the support protruding strip 211.

[0043] In the technical solution, when the comb tooth scraping strip 4 is assembled in the assembly groove 21, the support protruding strip 211 can be abutted and supported on the support bottom surface 412, thereby forming reliable and stable support for the connecting strip 41 of the comb tooth scraping strip 4, preventing the comb tooth 42 of the comb tooth scraping strip 4 from being broken due to stress, and prolonging the service life of the comb tooth scraping strip 4.

[0044] Referring to Figure 5 , in some embodiments, the comb tooth 42 has an outer side surface away from one side of the suction inlet channel 2, and when the dust collector is in use, the outer side surface forms an included angle ω with the suction contact plane of the suction cleaning object, and 0° < ω < 90°.

[0045] In the technical solution, ω is limited to between 0° and 90°, which can avoid the problem of pushing and pulling the dust collector to scrape the bed mattress when the comb tooth scraping strip 4 is at 0°, and can also avoid the problem of blocking the air inlet of the suction inlet channel 2 by the scraping strip when the comb tooth scraping strip 4 is at 90°, thereby affecting dust collection.

[0046] In some embodiments, a plurality of support ribs 111 are arranged in the suction inlet 11, each support rib 111 is arranged in the axial direction of the rolling brush assembly 3, and the comb tooth scraping strip 4 is located on the inner side of the support rib 111. It can be understood that, in order to prevent interference between each support rib 111 and the brush 31 of the rolling brush assembly 3, each support rib 111 is in the shape of a circular arc.

[0047] The support rib 111 can improve the overall structural strength of the adsorption inlet 11, especially when the adsorption inlet 11 has a large length, a plurality of support ribs 111 can be arranged at intervals to ensure the structural strength of the adsorption inlet 11, thereby preventing damage during use.

[0048] In some embodiments, the rolling brush assembly 3 further comprises a rolling cylinder 32, and the plurality of brushes 31 are detachably connected to the outer wall surface of the rolling cylinder 32.

[0049] In the technical solution, the plurality of brushes 31 are detachably connected to the outer wall surface of the rolling cylinder 32, which facilitates replacement of the damaged brushes 31 and prolongs the service life of the vacuum cleaner.

[0050] In some embodiments, one axial end surface of the rolling cylinder 32 is rotationally connected to the device housing 1, so that the position of the rolling cylinder 32 is reliably stable while ensuring smooth rotation of the rolling cylinder 32.

[0051] As a preferred embodiment, the outer wall surface of the rolling cylinder 32 is formed with a plug-in groove 321, and the tail end of each brush 31 is plugged into each plug-in groove 321.

[0052] The existing mite removal instrument (i.e. the aforementioned vacuum cleaner) generates a dust suction negative pressure when performing dust suction, and the airflow carries dust, mites and the like through the dust suction port (i.e. the aforementioned adsorption inlet 11), the main machine air inlet (i.e. the aforementioned adsorption air inlet 2) into the dust cup, and the airflow is discharged through the filter, the motor air inlet, the motor, and the main machine air outlet. During use, due to the high-speed rotation of the rolling brush and the Bernoulli effect caused by the suction force of the suction port, the cleaning surface is easily scraped up by the rolling brush (i.e. the aforementioned rolling brush assembly 3) and then wrapped, causing the rolling brush to stop rotating, making it difficult to push and pull the machine. To overcome the aforementioned technical deficiencies, the utility model increases the detachable anti-bed-sheet-winding comb tooth scraping strip 4 at the air inlet of the air duct, which not only prevents the bed sheet from winding, but also can be used for hair cleaning of the rolling brush.

[0053] In the specific use process, the comb tooth scraping strip (i.e. the aforementioned comb tooth scraping strip 4) is matched with the motor air duct matching groove (i.e. the aforementioned assembly groove 21) through the end (i.e. the connecting end 411 of the connecting strip 41), and is slid into assembly to the front end of the motor air duct air inlet. When the acararium is started, the roller brush rotates at high speed. At this time, the bristles (i.e. the aforementioned brush 31) on the roller brush cooperate with the comb teeth (i.e. the aforementioned comb teeth 42) in the rotating process, so as to block the probability of the bedsheet being wound around the roller brush after being rolled into. The comb tooth scraping strip can also be detached from the front end of the motor air duct air inlet, so as to facilitate the cleaning of the comb tooth scraping strip and the front end of the air duct. At the same time, the comb tooth scraping strip can also clean the hair and dirt on the surface of the bristles in the process of matching contact with the bristles. The structure not only can prevent the problem of rolling bedsheet in the use process of the acararium, but also can clean the hair, is convenient for the user to push and pull, and has good user experience.

[0054] Those skilled in the art can easily understand that the advantageous technical features of each mode described above can be freely combined and superimposed without conflict.

[0055] The above only describes the preferred embodiments of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above only describes the preferred embodiments of the present application, and does not limit the present application.
