[0027] like Figures 1 to 6As shown, a mite removal vacuum cleaner with a multi-stage cyclone includes a casing 1, a mite removal motor 6 arranged in the casing 1, a dust cup 2 connected to the upper end of the casing 1, a mite removal chamber shell 3 connected between the casing 1 and the dust cup 2, and a first wind cone tube 5 and a second wind cone tube 4 arranged in parallel on the mite removal chamber shell 3; wherein the inner cavity of the casing 1 is connected to the inner cavity of the dust cup 2 through the mite removal chamber shell 3, so that the suction force generated by the mite removal motor 6 sequentially passes through the second wind cone tube 4 and the first wind cone tube 5 to suck external dust mites into the mite removal chamber shell 3.

[0028] Specifically, the first wind cone tube 5 and the second wind cone tube 4 are both hollow pipe structures, and the mite removal chamber housing 3 is provided with a connector 23, the first wind cone tube 5 and the second wind cone tube 4 are clamped on the mite removal chamber housing 3 through the connector 23, the second wind cone tube 4 is clamped with the connector 23 and communicated with each other, the dust cup 2 is clamped on the mite removal chamber housing 3, so that the first wind cone tube 5 and the second wind cone tube 4 are covered in the dust cup 2, the bottom end of the mite removal chamber housing 3 is provided with a first air outlet 15, the housing 1 is provided with a first connecting port 16 connected with the first air outlet 15, and the housing 1 is connected with the mite removal chamber housing 3 through the first connecting port 16. The housing 1 is provided with a mite suction chamber 17 at one end close to the dust cup 2, the bottom end of the dust cup 2 is provided with an air inlet 19, and the housing 1 is provided with a second connecting port 18 connected with the air inlet 19, and the dust mites enter the dust cup 2 through the mite suction chamber 17 and the air inlet 19 in sequence.

[0029] like Figure 5 As shown, a partition plate 7 is provided in the dust cup 2 of the present embodiment. The partition plate 7 is a curved structure or a rectangular structure and the partition plate 7 and the dust cup 2 are an integrated structure. The partition plate 7 divides the dust cup 2 into a first chamber 9 and a second chamber 10 in which the first wind cone tube 5 and the second wind cone tube 4 are sequentially assembled. By setting the partition plate 7, the internal cavity of the dust cup 2 is divided into two independent spaces, which facilitates the first wind cone tube 5 and the second wind cone tube 4 to achieve multi-stage dust filtration and mite removal in the dust cup 2.

[0030] In this embodiment, a snap ring is provided at one end of the inner wall of the dust cup 2, and a slot which cooperates with the snap ring is provided on the outer wall of the mite removal chamber shell 3. The dust cup 2 and the mite removal chamber shell 3 can be detachably fastened together through the snap ring and the slot; after the first wind cone tube 5 and the second wind cone tube 4 filter the dust, the user removes the dust cup 2 from the mite removal chamber shell 3 through the snap ring, and can open the first chamber 9 and the second chamber 10 at one time, thereby realizing one-time cleaning, which is convenient for users to disassemble and clean.

[0031] It is worth mentioning that one end of the first wind cone tube 5 is provided with a filter screen 21 for filtering the airflow, and the end of the first wind cone tube 5 close to the filter screen 21 is provided with a disc-shaped partition 12, and the disc-shaped partition 12 and the first wind cone tube 5 are an integrated structure; in actual use, the airflow generated by the mite removal motor 6 carries the dust mites from the outside into the dust cup 2, and the dust mite airflow will be separated through the filter screen 21 after entering the first chamber 9, and a large volume of dust and garbage will be generated during the separation process, among which a part of the garbage is adsorbed on the filter screen 21 by the suction force generated by the mite removal motor 6, and another part of the larger volume of dust and garbage will adhere to the disc-shaped partition 12 when passing through the disc-shaped partition 12 of the first wind cone tube 5, and another part will adhere to the inner wall of the first chamber 9, while the smaller volume of dust mites will continue to enter the first wind cone tube 5 through the filter screen 21 with the airflow, and then enter the second chamber 10 for secondary separation.

[0032] It is worth mentioning that an opening 8 is provided on one side of the first wind cone tube 5 close to the filter screen 21, and a closure 11 is sleeved on one end of the first wind cone tube 5 close to the opening 8 for engaging with the dividing plate 7. Since the air inlet 19 in this embodiment is connected to the first chamber 9, the dividing plate 7 and the closure 11 cooperate to further separate the first chamber 9 and the second chamber 10. The dividing plate 7 and the extended end of the closure 11 together form a single tangential air outlet end of the air inlet 19. When the airflow passes through the opening 8 and enters the dust cup 2 using the single tangential air outlet end, due to the restriction of the dividing plate 7, the airflow carrying dust mites in the first chamber 9 can only enter the second chamber 10 through the opening 8 on the first wind cone tube 5, thereby preventing large particles of garbage deposited in the first chamber 9 from entering the second chamber 10, thereby improving the filtering effect of this embodiment.

[0033] like Figures 1 to 6As shown, in this embodiment, the second wind cone tube 4 is a cylindrical pipe, and a plurality of inner tubes 20 of the same shape and structure are arranged inside the second wind cone tube 4. The inner tube 20 is a conical pipe. By arranging the inner tube 20, the internal space of the second wind cone tube 4 can be fully utilized, so that the airflow entering the second chamber 10 can form a plurality of cyclones under the influence of the inner tube 20, so as to separate the dust mite airflow entering the second chamber 10 again for multiple times; in this embodiment, a total of 5 inner tubes 20 are arranged, and the dust mite airflow is divided into 5 streams in the second wind cone tube 4. The dust mite airflow entering the inner cavity of the second wind cone tube 4 will be separated in the inner tubes 20. 20 for secondary separation, some dust mites will be adsorbed by the inner wall of the second wind cone tube 4 and the outer surface of the inner tube 20 through the suction force generated by the mite removal motor 6, and the dust mite airflow will be further cleaned and brought into the mite removal chamber shell 3 through the inner tube 20 by the suction force; it is worth noting that one end of the connecting piece 23 is provided with a pipe opening for connection with the inner tube 20, and the inner tube 20 and the pipe opening are fastened together to effectively prevent the airflow in the inner tube 20 from flowing out, avoiding turbulence, and the inner tube 20 and the second wind cone tube 4 are an integrated structure, which reduces the number of parts and saves mold opening costs and assembly time.

[0034] like Figures 1 to 6 As shown, in order to further optimize the dust mite separation effect of the second wind cone tube 4, in this embodiment, the end of the second wind cone tube 4 close to the mite removal chamber housing 3 is the air outlet end 13, and the end of the second wind cone tube 4 away from the mite removal chamber housing 3 is the air inlet end 14. The inner diameter of the inner tube 20 gradually decreases from the air outlet end 13 to the air inlet end 14. By setting a gradually decreasing inner wall diameter, the secondary separation effect of the dust mite airflow in the second chamber 10 is optimized, and the large particles of dust in the dust mite airflow are separated and accumulated in the second chamber 10 and the second wind cone tube 4, thereby improving the airflow cleaning effect. It is worth noting that a dust removal sponge is provided in the mite removal chamber housing 3, the mite removal chamber housing 3 and the second wind cone tube 4 are interconnected, and a mesh window 22 is provided between the mite removal chamber housing 3 and the second wind cone tube 4. Through the mesh window 22 and the dust removal sponge, the separation efficiency of the dust mite airflow in the second chamber 10 is further improved, so that the mite removal motor 6 can extract cleaner gas, achieving a good dust removal and mite removal effect.

[0035] Working principle: connect an external power supply to start the mite removal device, the mite removal motor 6 starts to generate suction, and the external airflow containing dust mites enters the dust cup 2 from the mite suction chamber 17; the dust mite airflow enters the first chamber 9 from the air inlet 19, and the larger volume of dust and garbage after primary filtration in the first chamber 9 adheres to the disc-shaped partition 12 and the inner wall of the first chamber 9, and the dust mite airflow after primary filtration enters the first wind cone tube 5 through the suction port 21, and enters the second chamber 10 through the opening 8; the dust mite airflow entering the second chamber 10 forms multiple dust mite airflows under the influence of the inner tube 20, and is separated multiple times through the inner tube 20, and the large particles of dust in the dust mite airflow are further separated and accumulated in the second chamber 10, thereby improving the airflow cleaning effect, and finally through the mesh window 22 and the dust removal sponge in the mite removal chamber shell 3, the separation efficiency of the dust mite airflow in the second chamber 10 is further improved, so that the mite removal motor 6 can extract clean gas.
