[0036] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0039] See also Figure 1 and Figure 2 One embodiment of the present invention provides a filter mechanism 30, which is arranged on a dust removal device for filtering dust contained in the air. The dust removal device can be a dust collector 100 or an air purifier, that is, any dust removal device that needs to be provided with a filter mechanism 30 is applicable, and is not limited here.

[0040] The following is a detailed description of the technical solution of the present application using a vacuum cleaner 100 as an example. This embodiment is only used as an example and does not limit the technical scope of the present application. Furthermore, unnecessary components are omitted in the drawings in the embodiment to clearly show the technical features of the present application.

[0041] The vacuum cleaner 100 includes a housing 10, a separator 20, a filter mechanism 30 and a gas power mechanism 40, and the separator 20, the filter mechanism 30 and the gas power mechanism 40 are all connected to the housing 10. The separator 20 is used for gas-dust separation, the filter mechanism 30 is used for filtering fine dust carried in the gas formed after the gas-dust separation, and the gas power mechanism 40 is used for providing power for the gas to flow in the vacuum cleaner 100.

[0042] Specifically, a receiving chamber 17 is defined in the housing 10 , and an air inlet 11 and an air outlet 12 communicating between the outside and the receiving chamber 17 are also defined on the housing 10 .

[0043] The separator 20 is connected in the accommodating chamber 17 and is connected to the air intake port 11, the filter mechanism 30 is at least partially connected in the accommodating chamber 17 and the gas power mechanism 40 is connected in the accommodating chamber 17, the filter mechanism 30 is connected between the separator 20 and the air intake end 41 of the gas power mechanism 40, and the filter mechanism 30 is also connected between the exhaust end 42 of the gas power mechanism 40 and the exhaust port 12, and the gas filtered by the filter mechanism 30 flows through the air intake end 41 of the gas power mechanism 40 to the exhaust end 42 and then returns to flow to the filter mechanism 30 for filtration.

[0044] When the vacuum cleaner 100 is working, the gas power mechanism 40 provides power for the gas to flow in the vacuum cleaner 100. The external dust-carrying gas enters the vacuum cleaner 100 from the air intake port 11, and enters the filter mechanism 30 for filtration after being separated by the separator 20. The gas filtered by the filter mechanism 30 enters the air intake end 41 of the gas power mechanism 40, and returns from its exhaust end 42 to enter the filter mechanism 30 for filtration. After being filtered by the filter mechanism 30, the gas is discharged from the vacuum cleaner 100 from the exhaust port 12.

[0045] In the above-mentioned vacuum cleaner 100, both internal incoming air (wind entering the suction end 41 of the gas power mechanism 40) and external outgoing air (wind discharged to the outside through the exhaust end 42 of the gas power mechanism 40) are filtered by the same filter mechanism 30, thereby reducing the number of filter mechanisms 30, thereby simplifying the structure of the vacuum cleaner 100, and the number of filter mechanisms 30 is small, which is easy to clean.

[0046] At the same time, since the gas discharged from the exhaust end of the gas power mechanism 40 is returned to the filtering mechanism 30 for filtration and then discharged to the outside, compared with the prior art (in the prior art, the gas discharged from the exhaust end 42 of the gas power mechanism 40 is directly filtered and then discharged to the outside, so the noise generated by the gas power mechanism 40 has a shorter conduction path in the vacuum cleaner 100 and the noise transmitted to the outside is relatively large), the noise generated by the gas power mechanism 40 has a longer conduction path in the vacuum cleaner 100, thereby reducing the noise.

[0047] See also Figure 3 The housing 10 includes a body 13 and a handle 16. The accommodating cavity 17, the air inlet 11 and the air outlet 12 are all provided on the body 13. The handle 16 is provided on the body 13 and is disposed away from the air outlet 12. Thus, since the air outlet 12 is far away from the handle 16, when the user operates the vacuum cleaner 100 by holding the handle 16, the vacuum cleaner 100 is prevented from blowing directly on the human body.

[0048] The housing 10 further includes a first connecting tube 14 and a second connecting tube 15. Both the first connecting tube 14 and the second connecting tube 15 are connected in the accommodating chamber 17. The first connecting tube 14 is connected between the filter mechanism 30 and the suction end 41 of the gas power mechanism 40. The second connecting tube 15 is connected between the exhaust end 42 of the gas power mechanism 40 and the filter mechanism 30.

[0049] That is, the filter mechanism 30 is indirectly connected to the air intake end 41 of the gas power mechanism 40 through the first connecting pipe 14, and is indirectly connected to the air exhaust end 42 of the gas power mechanism 40 through the second connecting pipe 15. It is conceivable that in other embodiments, the filter mechanism 30 may also be directly connected to the air intake end 41 and the air exhaust end 42 of the gas power mechanism 40, which is not limited here.

[0050] See also Figure 4 and Figure 5 Specifically, the filtering mechanism 30 includes a first filter element 31 and a second filter element 32 which are connected to each other. The first filter element 31 is connected between the separator 20 and the first connecting pipe 14. The first filter element 31 is used to filter the gas formed after separation by the separator 20 so as to enter the suction end 41 of the gas power mechanism 40 through the first connecting pipe 14; the second filter element 32 is connected between the second connecting pipe 15 and the exhaust port 12. The second filter element 32 is used to filter the gas flowing from the exhaust end 42 of the gas power mechanism 40 to it through the second connecting pipe 15.

[0051] The first filter element 31 is hollow inside to form an outlet passage 311 having an outlet 312. The second filter element 32 includes a main body 324 and a filter portion 323. The main body 324 is mounted on the first filter element 31. The filter portion 323 is connected to the main body 324 and defines an inlet passage 321 having an inlet 322 with the main body 324. Specifically, one end of the first filter element 31 having the outlet 312 is connected to the first connecting pipe 14 through the separator 20, and one end of the second filter element 32 having the inlet 322 is connected to the second connecting pipe 15.

[0052] See also Figure 6 In this way, the gas separated by the separator 20 forms an airflow after being filtered by the first filter element 31 and enters the air outlet channel 311, and enters the first connecting pipe 14 from the air outlet 312 through the separator 20, and enters the air intake end 41 of the gas power mechanism 40 through the first connecting pipe 14, and then enters the air intake channel 321 from the air intake port 322 from the exhaust end 42 of the gas power mechanism 40, and flows to the outside from the exhaust port 12 after being filtered by the filter part 323 of the second filter element 32.

[0053] Furthermore, the first filter element 31 has an axial direction, and the second filter element 32 is coupled to one end of the axial direction of the first filter element 31 to facilitate the setting of the filter mechanism 30. It is conceivable that in other embodiments, the position where the second filter element 32 is coupled to the first filter element 31 is not limited.

[0054] See also Figure 7 Further, a first sealing portion 313 is formed at one end of the first filter element 31 away from the second filter element 32, and the first sealing portion 313 is sealed with the separator 20 to prevent gas from overflowing from between the first filter element 31 and the separator 20. A second sealing portion 325 is formed at one end of the second filter element 32 having the air inlet 322, and the second sealing portion 325 is sealed with the second connecting pipe 15 to prevent gas from overflowing from between the second filter element 32 and the second connecting pipe 15.

[0055] In another embodiment, the second filter element 32 further includes a third sealing portion 326 , which is connected to the main body 324 and seals with the housing 10 to prevent gas from leaking from between the second filter element 32 and the housing 10 .

[0056] Continue reading Figure 4 In one embodiment, the outlet direction of the air outlet 312, the inlet direction of the air inlet 322, and the axial direction of the first filter element 31 are parallel to each other. This arrangement facilitates the gas in the air outlet channel 311 to be discharged from the air outlet 312 to the first connecting pipe 14 along the axial direction, and facilitates the gas in the second connecting pipe 15 to enter the air inlet channel 321 from the air inlet 322 along the axial direction.

[0057] Furthermore, the air outlet channel 311 and the air inlet channel 321 are at least partially staggered in the axial direction, and the air outlet channel 311 is located at the periphery of the air inlet channel 321 along the radial direction of the first filter element 31, so as to facilitate the opening of the air outlet channel 311 and the air inlet channel 321. It can be understood that in other embodiments, the opening positions of the air outlet channel 311 and the air inlet channel 321 are not limited, such as the air outlet channel 311 and the air inlet channel 321 can also completely overlap in the axial direction, or the air outlet channel 311 is not located at the periphery of the air inlet channel 321 along the radial direction of the first filter element 31.

[0058] Specifically, the air outlet channel 311 is an axial channel, and the air inlet channel 321 is an annular channel arranged around the outer circumference of the air outlet channel 311 .

[0059] In one embodiment, the filter mechanism 30 further includes a handle 33, and the handle 33 is connected to the second filter element 32. The provision of the handle 33 can facilitate the assembly of the filter mechanism 30 on the housing 10 and the removal of the filter mechanism 30 from the housing 10.

[0060] Specifically, the end surface of the main body 324 facing away from the first filter element 31 is recessed to form a recessed position 3241, and the hand grip portion 33 is disposed in the recessed position 3241. It can be understood that in some other embodiments, the position of the hand grip portion 33 is not limited.

[0061] Continue reading Figure 5 In one embodiment, the filter portion 323 forms at least two filter layers connected between the air inlet channel 321 and the exhaust port 12, so that the gas flowing out of the air inlet channel 321 enters the exhaust port 12 after passing through at least two filter layers, and the filtering effect is better.

[0062] An embodiment of the present invention further provides a vacuum cleaner 100 including the filtering mechanism 30 described above.

[0063] The filter mechanism 30 and the vacuum cleaner 100 provided in the embodiment of the present invention have the following beneficial effects:

[0064] 1. The filter mechanism 30 includes a first filter element 31 and a second filter element 32, so that the air inlet of the air suction end 41 of the gas power mechanism 40 is filtered by the first filter element 31, and the air outlet of the air discharge end 42 of the gas power mechanism 40 is returned to the filter mechanism 30 and filtered by the second filter element 32 thereof. In this way, the internal air inlet and the external air outlet of the vacuum cleaner 100 are filtered by the same filter mechanism 30, thereby reducing the number of filter mechanisms 30, thereby simplifying the structure of the vacuum cleaner 100;

[0065] 2. Since the gas power mechanism 40 is connected to the housing 10, and its exhaust end 42 is folded back to the filter mechanism 30 and communicated with the exhaust port 12 through the second filter element 32 of the filter mechanism 30, compared with the prior art (in the prior art, the gas discharged from the exhaust end 42 of the gas power mechanism 40 is directly filtered and then discharged to the outside, so the conduction path of the noise generated by the gas power mechanism 40 in the vacuum cleaner 100 is shorter, and the noise transmitted to the outside is larger), the conduction path of the noise generated by the gas power mechanism 40 in the vacuum cleaner 100 is longer, thereby reducing the noise;

[0066] 3. The handle 16 is disposed on the side of the body 13 of the housing 10 facing away from the exhaust port 12 , so that the exhaust port 12 is away from the handle 16 . When the user operates the vacuum cleaner 100 by holding the handle 16 , the vacuum cleaner 100 is prevented from blowing directly onto the human body.

[0067] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
