[0002] In the surface cleaning devices such as electric dust mop, scrubber, vacuum cleaner, and robot sweeper (also known as "dibao") having a suction port (the suction port sucks dust and other dirt into the dust bin or dirt collection chamber), using a cyclone separator to separate the airflow containing dirt is an important technical means. The cyclone separator not only realizes a non-consumable design, but also has good separation effect. Currently, the technical scheme for deep cleaning of the cyclone separator mainly adopts axial splitting to realize cleaning. This kind of technical scheme is universal in the industry and has been used for a long time, forming an inertial understanding. However, the operation steps of splitting each part axially for cleaning are more and the operation is more complex.

[0003] The applicant hopes to break through the existing technical understanding limit and further improve the cleaning convenience while using the cyclone separator. Therefore, the applicant will propose a surface cleaning device in the present disclosure to improve the cleaning convenience. SUMMARY

[0011] Preferably, the cyclone chamber and the dust bin are arranged in sequence along the axial direction of the cyclone chamber.

[0012] Preferably, a dust blocking partition is arranged between the cyclone chamber and the dust bin.

[0013] Preferably, the first part is fixedly arranged in the body of the surface cleaning device, and the second part is arranged to be openable relative to the first part to open the cyclone chamber, and the inner surface of the second part is exposed outside the body after the second part is opened.

[0014] Preferably, the air outlet assembly is arranged on the second part, and the air outlet assembly is also exposed outside the body after the second part is opened.

[0015] Preferably, for the case that a dust blocking partition is arranged between the cyclone chamber and the dust bin, the dust blocking partition is fixedly arranged, and the second part is arranged to be openable relative to the dust blocking partition.

[0016] Preferably, the tangential inlet is arranged on the second part, and the tangential inlet is also exposed outside the body after the second part is opened.

[0018] Preferably, the second part includes an axial extension part, the axial extension part serves as the third part or the fourth part of the dust bin, and the axial extension part is opened together with the second part to detach the third part and the fourth part for dust discharge.

[0019] Preferably, during the cleaning operation of the surface cleaning device, the axial direction of the cyclone chamber is arranged substantially parallel to the surface to be cleaned.

[0020] Preferably, the surface cleaning device further comprises a filter, the filter is connected in communication with the air suction assembly through an air suction flow channel, and the filter, the cyclone chamber and the dust bin are arranged in sequence along the axial direction of the cyclone chamber in the body.

[0023] Although it has a cyclone separator, the peripheral wall is composed of two horizontally separable parts. Therefore, the first and second parts can be separated for cleaning. This makes it easier to directly pour out the dirt in the cyclone chamber and provides more operating space for cleaning, rather than cleaning by axially splitting the parts and separating the first and second parts. The operation is more convenient and simple. Therefore, the technical solution disclosed in this invention breaks with conventional thinking. Moreover, this invention not only has a cyclone separator, but also improves the convenience of cleaning. Attached Figure Description

Detailed Implementation

[0034] The following description is presented to enable any person skilled in the art to practice the application as claimed. The embodiments disclosed in the following description are only examples of the application and are not intended to limit the scope, applicability or configuration of the application in any way. Various changes to the examples disclosed in the following description can be made by one skilled in the art without departing from the spirit and scope of the application.

[0035] In the present disclosure, it should be noted that dust is a general term, not only refers to dust, but also refers to dirt, garbage and the like that can be cleaned by a surface cleaning device.

[0036] The application will be further described in detail as follows:

[0037] The present disclosure provides a surface cleaning device, and the disclosed technical solutions can be applied to various products, such as electric dust mop, dust collector, sweeper, robot sweeper (also known as treasure) and the like. The surface cleaning device referred to in the present disclosure generally refers to a household or small surface cleaning device, which is also a feature of the surface cleaning device provided by the present disclosure, that is, the overall structure size is required to be small, which can be applied to small space cleaning.

[0038] For ease of understanding, as shown in Figures 1 to 9 , the present disclosure specifically exemplifies a brush part of a surface cleaning device, which can be used in electric dust mop, dust collector, sweeper, robot sweeper (also known as treasure) and the like. If it is a robot sweeper, a suction assembly and a self-walking structure can be added on the basis of the brush part to realize the robot sweeper, and at this time the brush part is the body of the robot sweeper.

[0039] The brush part includes a body 1, and the body 1 is provided with a filter 21, a cyclone chamber 3 and a dust bin 8. The filter 21 is connected in communication with the air suction assembly through an air outlet pipe 18. The body 1 further includes an air outlet assembly 2 and a peripheral wall surrounding the air outlet assembly 2. The air outlet assembly 2 is provided with a filter screen 17, and the cyclone chamber 3 is formed between the air outlet assembly 2 and the peripheral wall surrounding the air outlet assembly 2. The peripheral wall is provided with a tangential inlet 4, and the peripheral wall is composed of two transversely detachable parts, which are respectively referred to as a first part 5 and a second part 6. As shown in Figure 4 , 5 In order to improve the sealing performance after splicing, a sealing gasket 23 is arranged between the first part 5 and the second part 6, as shown in Figure 6 , 7 When in the separated state, the cyclone chamber 3 is in an open state, thereby facilitating cleaning. Further, when in the separated state, the dust bin 8 is also in an open state, thereby facilitating dust dumping. As shown in Figure 9The arrows in the figure indicate the main flow direction of the suction air flow.

[0040] In some embodiments, as shown in Figure 3 , 8 , the filter 21, the cyclone chamber 3 and the dust bin 8 are arranged in the machine body 1 in sequence along the axial direction of the cyclone chamber 3. In this way, the structure is more compact.

[0041] In some embodiments, as shown in Figure 6 , 7 , the first part 5 and the second part 6 are arranged in an up-down manner, and further comprising a cover plate 22, the second part 6 and the axial extension part are arranged on the cover plate 22, and the cover plate 22 is opened and closed to separate / splice the second part 6 from the first part 5 and open / close the dust bin 8. In the floor brush part, the first part 5 and the second part 6 are arranged in an up-down manner, which is conducive to reducing the height of the floor brush part.

[0042] In some embodiments, as shown in Figure 6 , 7 , the first part 5 and the second part 6 are connected by a splicing structure that can be relatively rotated to open and close, specifically, a rotatable part 7 is arranged between one end of the cover plate 22 and the machine body 1, so as to realize a rotatable connection, and the rotatable connection enables the cover plate 22 to swing open and close around the one end. In this way, the structure is simple and reliable in opening and closing. In order to better fix the cover plate 22 and facilitate opening, as shown in Figure 3 , the other end of the cover plate 22 is connected to the machine body 1 through a connection structure formed by a button 13, an elastic member 14, a first hook part 15 and a second hook part 16, the button 13 and the elastic member 14 are arranged on the side wall of the machine body 1, the button 13 adopts a lever structure, the button 13 is rotatably connected to a rotating support arranged on the side wall, the elastic member 14 is arranged between the upper end of the button 13 and the side wall, the first hook part 15 is arranged at the lower end of the button 13, and the other end of the cover plate 22 is provided with the second hook part 16 matched with the first hook part 15. When the button 13 is pressed, the first hook part 15 releases the second hook part 16, so that the cover plate 22 is opened. In order to enable the cover plate 22 to be better automatically opened, the rotatable part 7 is provided with a torsional spring, and through the elastic force of the torsional spring, after the first hook part 15 releases the second hook part 16, the cover plate 22 can be better automatically opened.

[0043] In some embodiments, as shown in Figure 3 , 8 , 9, the cyclone chamber 3 is connected with the dust bin 8, and the cyclone chamber 3 and the dust bin 8 are communicated through a dust outlet, the dust outlet and the tangential inlet 4 are arranged in a staggered manner along the axial direction of the cyclone chamber 3, and the dust outlet adopts a tangential outlet 9 and / or an axial outlet 10. In this way, the dust can be better introduced into the dust bin 8 through the tangential outlet 9 and / or the axial outlet 10, which is conducive to cyclone separation.

[0044] In some embodiments, as shown in Figure 3 , 6 , 8, 9, a dust blocking partition 12 is arranged between the cyclone chamber 3 and the dust bin 8. In this way, dust entering the dust bin 8 can be prevented from being sucked into the cyclone chamber 3 again.

[0045] In some embodiments, the air outlet end 11 of the air outlet assembly 2, the tangential inlet 4, and the dust outlet are arranged in sequence along the axis direction of the cyclone chamber 3. In this way, the structure is compact, and a better cyclone separation structure is formed.

[0046] In some embodiments, as shown in Figure 5 , 6 , 7, the dust bin 8 is composed of two transversely detachable parts, which are respectively referred to as a third part and a fourth part. The third part is connected to the first part 5, and the fourth part is connected to the second part 6. When the first part 5 and the second part 6 are detached, the third part and the fourth part are also detached at the same time. In this way, dust in the cyclone chamber 3 and dust in the dust bin 8 can be poured out together, which is more convenient for use and cleaning.

[0047] In some embodiments, as shown in Figure 6 , 7 , the first part 5 is fixedly arranged in the body 1 of the surface cleaning device, and the second part 6 is arranged to be openable relative to the first part 5 to open the cyclone chamber 3. After the second part 6 is opened, the inner surface of the second part 6 is exposed outside the body 1. In this way, the cyclone separation structure does not need to be additionally detached for cleaning, but only needs to be opened relative to the first part 5, and after cleaning is completed, the second part 6 is reassembled with the first part 5.

[0048] In some embodiments, as shown in Figure 6 , 7 , the air outlet assembly 2 is arranged on the second part 6, and after the second part 6 is opened, the air outlet assembly 2 is also exposed outside the body 1. In this way, the air outlet assembly 2 can be more conveniently cleaned.

[0049] In some embodiments, as shown in Figure 6 , 7 , based on the air outlet assembly 2 being arranged on the second part 6, a clever design is made. Specifically, for the case where the dust blocking partition 12 is arranged between the cyclone chamber 3 and the dust bin 8, the dust blocking partition 12 is fixedly arranged, and the second part 6 is arranged to be openable relative to the dust blocking partition 12. In this way, after the second part 6 is opened, the air outlet assembly 2 is exposed outside the body 1, and the second part 6 is not blocked by the dust blocking partition 12, which is fixed, so that cleaning is more convenient.

[0050] In some embodiments, as shown in Figure 6 , 7As shown, the tangential inlet 4 is arranged on the second part 6, and after the second part 6 is opened, the tangential inlet 4 is also exposed outside the body 1. After such design, on the one hand, the tangential inlet 4 can be cleaned more conveniently, and on the other hand, the cyclone chamber 3 can be arranged close to the surface of the body 1, and for the floor brush part, that is, the cyclone chamber 3 is arranged lower, because the tangential inlet 4 needs to be arranged tangentially, if the tangential inlet 4 is arranged higher, the cyclone chamber 3 will be arranged higher as a whole, so when the tangential inlet 4 is arranged on the second part 6, the tangential inlet 4 can be arranged closer to the surface of the body 1. Arranging the cyclone chamber 3 lower will bring additional benefits, such as facilitating the reduction of the height of the body 1, facilitating the exposure of the internal structure of the cyclone chamber 3 for cleaning, and the like.

[0051] In some embodiments, as shown in Figure 6 , 7 , the body 1 is provided with a collection part 19 for gathering dirt on the cleaned surface 20, the collection part 19 is provided with a collection suction port 25, the tangential inlet 4 and the collection suction port 25 are connected in communication separately, after the second part 6 is opened, the tangential inlet 4 and the collection suction port 25 are separated, and after the second part 6 is reconnected with the first part 5, the tangential inlet 4 and the collection suction port 25 are reconnected in communication. After such design, on the basis of the design that the second part 6 and the first part 5 are connected in the disclosure, better cleaning performance can also be maintained, and the collection part 19 cannot be arranged due to the connection design of the second part 6 and the first part 5.

[0052] In some embodiments, as shown in Figure 6 , 7 , the second part 6 includes an axially extending part which serves as a third part or a fourth part of the dust bin 8, for example, when the third part is fixed in the body 1, the axially extending part serves as a fourth part of the dust bin 8, and the axially extending part is opened together with the second part 6 to separate the third part and the fourth part for dust dumping. In this example, the axially extending part is part of the cover plate 22, in order to facilitate movement above the cleaned surface 20, the outer surface of the cover plate 22 is arranged as a plane, and in order to simplify the structure, the cover plate 22 is generally a flat plate.

[0053] In some embodiments, as shown in Figure 6 , 6 , 7, the lower surface of the body is provided with a plurality of rollers 24, which facilitate the movement of the floor brush part on the cleaned surface 20 for cleaning work, wherein the lower side of the cover plate 22 is provided with at least one roller 24, which is used to support the cleaned surface 20, and through the support of the roller 24, the cover plate 22 can be automatically closed, and the automatic closing is realized through the cooperation of the first hook part 15 and the second hook part 16.

[0054] In some embodiments, as shown in Figure 5 ,2 As shown in FIG. 3, the axis of the cyclone chamber 3 is arranged substantially parallel to the surface 20 to be cleaned during the cleaning operation of the surface cleaning device. In this way, the cyclone chamber 3 and the tangential inlet 4 are arranged closer to the surface 20 to be cleaned, so that the cleaning operation can be performed more efficiently, and the height of the machine body 1 can be reduced.

[0055] The technical solution of the machine body 1 further comprising the air outlet assembly 2 and the peripheral wall surrounding the air outlet assembly 2, the air outlet assembly 2 being provided with the filter screen 17, the cyclone chamber 3 being formed between the air outlet assembly 2 and the peripheral wall surrounding the air outlet assembly 2, the peripheral wall being provided with the tangential inlet 4, and the peripheral wall being composed of two transversely detachable parts, i.e., the first part 5 and the second part 6, can be used not only in the brush part, but also in other parts of the surface cleaning device, such as a hand-held cyclone separation part, a cyclone separation part of a table-type vacuum cleaner, etc. In this case, the cyclone separation part is not arranged close to the surface 20 to be cleaned, and the cyclone separation part performs the cyclone separation operation on the airflow delivered through a relatively long suction duct.

[0056] In understanding the present application, the above description can be referenced in conjunction with the other embodiments / attachments Figure 1 Figure 1 It is understood that the above description is not exhaustive.

[0057] The above description is only an embodiment of the present application for illustration, and any equivalent changes or modifications made to the structure, features and principles described in the scope of the present patent protection are included in the scope of the present patent protection.
