[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0031] In order to solve the problem that hair and other debris on the roller brush of a sweeping robot in the prior art are difficult to handle, the present application provides a sweeping robot.

[0032] Furthermore, the sweeping machine described below in this application generally refers to a sweeping robot.

[0033] like Figures 1 to 8As shown, the sweeping machine in the present application includes a housing 10 and a roller brush assembly 20, a comb assembly 30, a blade assembly 40 and a driving assembly 50 respectively arranged on the housing 10. The comb assembly 30 extends toward the roller brush assembly 20; in the rotation direction of the roller brush assembly 20, the blade assembly 40 is arranged downstream of the comb assembly 30; the driving assembly 50 is drivingly connected to the roller brush assembly 20 and the blade assembly 40 respectively, so that at least a part of the roller brush assembly 20 rotates relative to the housing 10 and at least a part of the blade assembly 40 moves relative to at least another part of the blade assembly 40.

[0034] When the sweeper in the present application is used, the sweeper can clean the ground through the roller brush assembly 20, and in the process of cleaning, since the sweeper also has a comb tooth assembly 30 and the comb tooth assembly 30 extends toward the roller brush assembly 20, the comb tooth assembly 30 can be used to comb and collect the hair 70 and other debris wrapped around the roller brush assembly 20, and since the blade assembly 40 is located at the downstream position of the comb tooth assembly 30 in the rotation direction of the roller brush assembly 20, the hair on the comb tooth assembly 30 can be cut by the blade assembly 40. In addition, since at least a part of the blade assembly 40 can move relative to at least another part of the blade assembly 40, the cutting effect of the blade assembly 40 on the hair 70 can be effectively guaranteed. Therefore, when the sweeper in the present application is used, the cleaning difficulty of the sweeper can be effectively reduced, and the user's experience can be improved. Therefore, the sweeper in the present application effectively solves the problem that it is difficult to handle the hair and other debris on the roller brush of the sweeping robot in the prior art. At the same time, since the blade assembly 40 in the present application is located downstream of the comb tooth assembly 30, the comb tooth assembly 30 can reduce or avoid direct contact between the blade assembly 40 and items such as carpets in the use environment of the sweeper, thereby ensuring that the blade assembly 40 will not damage other items while cutting hair. On the other hand, in the present application, since the drive assembly 50 drives the roller brush assembly 20 and the blade assembly 40 at the same time, the same power source can achieve the driving effect of multiple structures, which can help reduce the production cost of the sweeper and miniaturize the design.

[0035] Optionally, the drive assembly 50 drives at least a portion of the blade assembly 40 to reciprocate along the axial direction of the roller brush assembly 20; and / or the drive assembly 50 drives at least a portion of the blade assembly 40 to reciprocate between the comb assembly 30 and at least another portion of the blade assembly 40. In a specific embodiment of the present application, Figure 4 and Figure 5As shown, the blade assembly 40 includes a first blade 41 and a second blade 42, the second blade 42 is closer to the comb assembly 30 relative to the first blade 41, and the second blade 42 is drivingly connected to the driving assembly 50 and can move relative to the first blade 41. In addition, in the present application, the blade portion of the first blade 41 and the blade portion of the second blade 42 can be serrated, so that the hair can be cut by the relative movement between the first blade 41 and the second blade 42.

[0036] Optionally, when the driving assembly 50 drives the second blade 42 to move relative to the first blade 41, the second blade 42 reciprocates along the axial direction of the roller brush assembly 20. Of course, the movement between the second blade 42 and the first blade 41 can also be that the second blade 42 reciprocates between the comb assembly 30 and the first blade 41. Through the above-mentioned movement, a shearing effect on the hair can be formed between the first blade 41 and the second blade 42, so that the hair entangled on the roller brush assembly 20 can be effectively removed.

[0037] Specifically, Figure 5 and Figure 8 As shown, the distance between the first blade 41 and the axis of the roller brush assembly 20 is smaller than the distance between the comb tooth assembly 30 and the axis of the roller brush assembly 20, and the distance between the second blade 42 and the axis of the roller brush assembly 20 is smaller than the distance between the comb tooth assembly 30 and the axis of the roller brush assembly 20. For the above distances, it generally means that the distance between the end of the first blade 41 close to the roller brush assembly 20 and the end of the second blade 42 close to the roller brush assembly 20 and the axis of the roller brush assembly 20 is smaller than the distance between the end of the comb tooth assembly 30 close to the roller brush assembly 20 and the axis of the roller brush assembly 20. In other words, in the axial direction toward the roller brush assembly 20, the first blade 41 and the second blade 42 will not protrude from the comb tooth assembly 30. By setting in this way, the contact between the blade assembly 40 and items such as carpets can be further reduced, and only hair is cut.

[0038] Optionally, the first blade 41 and the second blade 42 are both arranged along the axial direction of the roller brush assembly 20. This arrangement can further effectively ensure the cutting effect of the blade assembly 40 on hair.

[0039] Continuously, if Figure 8As shown, the comb tooth assembly 30 includes a plurality of tooth bodies 31, which are arranged at intervals along the axial direction of the roller brush assembly 20, and the tooth bodies 31 extend toward the roller brush assembly 20, and the side of the tooth body 31 away from the blade assembly 40 has at least one opening, that is, the opening direction of the tooth body 31 is opposite to the rotation direction of the roller brush assembly 20. This arrangement can ensure that the tooth body 31 can collect hair through the opening every time the roller brush assembly 20 rotates one circle. Of course, in the present application, the comb tooth assembly 30 can also be set to other structures, as long as it is ensured that the comb tooth assembly 30 can collect the hair on the roller brush assembly 20 and can be cut by the blade assembly 40 after collection.

[0040] Alternatively, if Figure 5 and Figure 7 As shown, the roller brush assembly 20 includes a main body 21 and a plurality of bristles 22. The driving assembly 50 is drivingly connected to the main body 21; the bristles 22 are arranged on the main body 21 at intervals, and the distance between the comb tooth assembly 30 and the main body 21 is less than the length of the bristles 22. In other words, the comb tooth assembly 30 is arranged within the rotation radius of the bristles 22. That is to say, in the present application, the roller brush assembly 20 and the comb tooth assembly 30 are interference fit, and when the main body 21 drives the bristles 22 to rotate, the bristles 22 can contact the comb tooth assembly 30 when passing through the comb tooth assembly 30, and the bristle 22 assembly can also be deformed, thereby ensuring that the comb tooth assembly 30 can effectively collect the hair on the bristles 22.

[0041] In a specific embodiment of the present application, Figures 4 to 6 As shown, the driving assembly 50 includes a driving part 51, a reduction box structure 52 and a blade driving part 53. The driving part 51 is arranged on the housing 10; the driving part 51 is drivingly connected to the roller brush assembly 20 through the reduction box structure 52; the blade driving part 53 is drivingly connected to the blade assembly 40, and the driving part 51 is drivingly connected to the blade driving part 53 through the reduction box structure 52. Optionally, the blade driving part 53 can be a cam structure, a crank connecting rod mechanism, an eccentric wheel mechanism, etc., as long as the movement form of the blade assembly 40 can be realized.

[0042] Alternatively, if Figure 1 and Figure 7 As shown, the sweeper also includes a dust box 60, which is arranged on the housing 10, and the opening of the dust box 60 is arranged corresponding to the side of the blade assembly 40 away from the comb assembly 30. This arrangement can ensure that the cut hair can more easily enter the dust box 60 along the dust collection direction.

[0043] Optionally, at least a portion of the roller brush assembly 20 is located inside the shell 10, at least another portion of the roller brush assembly 20 is arranged outside the shell 10, and the comb tooth assembly 30 and / or the blade assembly 40 are arranged corresponding to the portion of the roller brush assembly 20 located inside the shell 10.

[0044] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0045] 1. Improve the cleaning effect of the sweeping robot by dealing with the hair entanglement problem in real time;

[0046] 2. By automatically dealing with the problem of hair entanglement, it reduces the difficulty of users cleaning the sweeper and improves the user experience;

[0047] 3. No additional power source is required. The existing motor and reduction gearbox system that drives the roller brush to rotate is used to drive the hair cutting device to reciprocate, which reduces system complexity and improves product reliability.

[0048] 4. By arranging the hair cutting structure inside the comb teeth, direct contact with objects such as carpets in the use environment can be avoided, so that the hair cutting process does not damage other objects.
