Technical Field
[0001] The present application relates to the technical field of cleaning appliances, and in particular to a scraping assembly, a base station and a cleaning robot. Background Art
[0002] Cleaning robots are a type of household appliance that is widely used in our daily lives. Cleaning robots usually use a cleaning member to absorb stains on the surface to be cleaned, and a scraping component to scrape away the stains on the surface of the cleaning member so that the cleaning member can continue to absorb the stains on the surface to be cleaned.
[0003] However, after the existing scraping assembly scrapes away the dirt on the surface of the cleaning member, some dirt will remain on the surface of the scraping assembly, so it is usually necessary to manually disassemble the scraping assembly to clean it. This increases the difficulty of cleaning the scraping assembly and makes it inconvenient to clean it. Summary of the Invention
[0004] In response to the problem of high difficulty in cleaning existing scraping components, the present application proposes a scraping component, a base station and a cleaning robot, which have the technical effect of achieving self-cleaning of the scraping component.
[0005] A dirt scraping assembly, comprising:
[0006] Mounting seat;
[0007] A cleaning member, movably connected to the mounting seat and used for cleaning the surface to be cleaned;
[0008] a scraping member located beside the cleaning member, one end of the scraping member being connected to the mounting seat, and the other end extending toward the surface to be cleaned and at least partially abutting against the surface of the cleaning member;
[0009] Wherein, when the scraping member is in the scraping state and the self-cleaning state, the rotation direction of the cleaning member is opposite.
[0010] In one embodiment, in the scraping state, the scraping member abuts against the surface of the cleaning member and forms a first abutment area. In the self-cleaning state, the scraping member abuts against the surface of the cleaning member and forms a second abutment area. The first abutment area is smaller than the second abutment area.
[0011] In one embodiment, the scraping member includes a main body and a scraping portion, one end of the main body is hinged to the mounting seat, and the other end is hinged to the scraping portion;
[0012] In the self-cleaning state, the main body and the scraping portion are both in contact with the surface of the cleaning member.
[0013] In one embodiment, an elastic member is provided at the connection between the main body and the scraping portion, one end of the elastic member is connected to the main body, and the other end of the elastic member is connected to the scraping portion;
[0014] Under the action of external force, the main body, the scraping part and the elastic member are all in contact with the cleaning member; when the external force is removed, the main body and the scraping part are driven by the elastic member to return to their original positions.
[0015] In one embodiment, a rotating shaft is further provided at the connection point, and the elastic member is a torsion spring, which is sleeved on the rotating shaft.
[0016] In one embodiment, the surface of the scraping portion is further covered with a barrier layer, and the barrier layer is located at the connection between the scraping portion and the main body.
[0017] In one embodiment, the scraping assembly further includes a first abutment portion, which is located on both sides of the scraping member in the axial direction of the cleaning member, and is used to drive the scraping member toward the cleaning member under the abutment of external force until the scraping member is in a self-cleaning state and abuts against the surface of the cleaning member.
[0018] In one embodiment, the free end of the scraping member forms a bent portion, which is recessed in a direction away from the cleaning member and is used to accommodate stains.
[0019] In one embodiment, the cleaning member is cylindrical in structure, and the surface of the scraping member facing the cleaning member is an arc surface. In the self-cleaning state, the scraping member and the cleaning member are completely fitted together.
[0020] The present application also provides a base station for use with the above-mentioned scraping assembly. The base station includes a base having a cavity formed therein and an opening connecting the cavity with the outside world. The scraping assembly enters the cavity through the opening for self-cleaning.
[0021] In one embodiment, the inner wall of the cavity is provided with a second abutment portion, and the scraping assembly further includes a first abutment portion. In the axial direction of the cleaning member, the first abutment portion is located on both sides of the scraping member, and the first abutment portion abuts against the second abutment portion to move the scraping member of the scraping assembly toward the cleaning member of the scraping assembly.
[0022] The present application also provides a cleaning robot comprising the above-mentioned scraping assembly.
[0023] In one embodiment, the above-mentioned base station is further included, and the base station is used in conjunction with the scraping component.
[0024] Compared to the prior art, the scraping assembly, base station, and cleaning robot provided in the embodiments of the present application, in conjunction with the scraping member, enable the cleaning member to rotate clockwise in the scraping state and counterclockwise in the self-cleaning state. This allows the cleaning member to re-adsorb dirt trapped between the scraping member and the cleaning member, and the direction of rotation during this phase is opposite to the direction of rotation of the cleaning member in the scraping state. The scraping member then scrapes away any re-adsorbed dirt on the cleaning member's surface. In this way, the scraping member can be cleaned by the cleaning member and the scraping member, achieving self-cleaning of the scraping member without the need for manual cleaning of the scraping member, thus reducing the difficulty of cleaning the scraping assembly.

[0036] Please refer to Figure 1 Some embodiments of the present application provide a scraping assembly 100. The scraping assembly 100 includes a mounting seat 10, a cleaning member 20, and a scraping member 30. The cleaning member 20 can be movably connected to the mounting seat 10 and is used to clean the surface to be cleaned. The scraping member 30 can be located next to the cleaning member 20, one end of the scraping member 30 can be connected to the mounting seat 10, and the other end can extend toward the direction of the surface to be cleaned and at least partially abut against the surface of the cleaning member 20. Specifically, when the scraping member 30 is in the scraping state and the self-cleaning state, the rotation direction of the cleaning member 20 is opposite.
[0037] For ease of explanation, the following description will be made with reference to a scenario in which the scraping assembly 100 switches from the scraping state to the self-cleaning state.
[0038] like Figure 3 As shown, the scraping assembly 100 is in the scraping state. The cleaning member 20 can rotate clockwise. When the cleaning member 20 contacts the surface to be cleaned, it absorbs the stains on the surface to be cleaned and causes the stains to rotate clockwise. Because the free end of the scraping member 30 contacts the surface of the cleaning member 20, after absorbing the stains, a portion of the cleaning member 20 can move toward the scraping member 30. When the stains contact the scraping member 30, the scraping member 30 can cause the stains to fall off the surface of the cleaning member 20. In this way, the stains on the surface of the cleaning member 20 are cleaned.
[0039] It can be understood that at this time, stains remain on the surface of the scraping member 30 facing the cleaning member 20 .
[0040] like Figure 2 As shown, when the scraping assembly 100 switches from the scraping mode to the self-cleaning mode, the cleaning member 20 can rotate counterclockwise. This allows dirt trapped between the scraping member 30 and the cleaning member 20 to be re-absorbed by the cleaning member 20 and rotate counterclockwise with the cleaning member 20. As the cleaning member 20 continues to rotate, the re-absorbed dirt can approach the free end of the scraping member 30 and fall off the cleaning member 20 under the action of the free end.
[0041] During this process, the cleaning member 20 can be used to absorb the stains on the surface of the scraping member 30 facing the cleaning member 20, and cooperate with the scraping member 30 to discharge the stains remaining between the scraping member 30 and the cleaning member 20 out of the scraping member 30, thereby cleaning the scraping member 30.
[0042] In summary, in conjunction with the scraping member 30, the cleaning member 20 can rotate clockwise in the scraping mode and counterclockwise in the self-cleaning mode. This allows the cleaning member 20 to re-adsorb dirt trapped between the scraping member 30 and the cleaning member 20. The direction of rotation during this phase is opposite to the direction of rotation of the cleaning member 20 in the scraping mode, allowing the scraping member 30 to scrape away any re-adsorbed dirt on the surface of the cleaning member 20. In this manner, the cleaning member 20 and the scraping member 30 can clean the scraping member 30, achieving self-cleaning of the scraping member 30. Manual cleaning of the scraping member 30 is eliminated, reducing the difficulty of cleaning the scraping assembly 100.
[0043] It should be noted that the cleaning member 20 can also rotate counterclockwise in the scraping state, and can rotate clockwise in the self-cleaning state. The rotation direction of the cleaning member 20 in different states can be determined according to actual conditions and is not specifically limited here.
[0044] In some examples, in the scraping state, the scraping member 30 abuts against the surface of the cleaning member 20 to form a first abutment area. In the self-cleaning state, the scraping member 30 abuts against the surface of the cleaning member 20 to form a second abutment area, and the first abutment area is smaller than the second abutment area.
[0045] In this way, when the scraping assembly 100 enters the self-cleaning state, the contact area between the scraping member 30 and the cleaning member 20 is larger, and the cleaning member 20 can absorb more dirt in a single rotation, thereby improving the self-cleaning efficiency of the scraping member 30.
[0046] In some embodiments, as Figure 1 As shown, the cleaning member 20 can be cylindrical. The surface of the scraping member 30 facing the cleaning member 20 can be a curved surface. In the self-cleaning mode, the scraping member 30 and the cleaning member 20 can be completely in contact. This increases the contact area between the cleaning member 20 and the scraping member 30, thereby improving the adsorption effect of the cleaning member 20 and reducing the probability of residual stains on the surface of the scraping member 30.
[0047] In some embodiments, the scraping member 30 may be a unitary structure. For example, the scraping member 30 may be a component having an elastic region. When the scraping member 30 is in the scraping state, a certain space may exist between the scraping member 30 and the cleaning member 20, which can be used to accommodate dirt that falls off the cleaning member 20. When the scraping member 30 is in the self-cleaning state, it may move closer to the cleaning member 20 and abut against it.
[0048] In other embodiments, the scraping member 30 may be composed of multiple components, for example, Figure 1 As shown, the scraping member 30 may include a main body and a scraping portion 32. One end of the main body is hinged to the mounting base 10, and the other end is hinged to the scraping portion 32. In the self-cleaning state, the main body and the scraping portion 32 may both fit the surface of the cleaning member 20.
[0049] Please continue reading Figure 1 When the scraping member 30 is in the scraping state, assuming that the cleaning member 20 rotates in a first direction (e.g., clockwise), a dirt-receiving space is formed between the main body, the scraping portion 32, and the cleaning member 20. Dirt absorbed by the cleaning member 20 falls into the dirt-receiving space under the action of the scraping portion 32.
[0050] When the scraping member 30 is in the self-cleaning state, the cleaning member 20 can rotate in a second direction (e.g., counterclockwise). Under the action of an external force, both the main body and the scraping portion 32 can move toward the cleaning member 20. For example, the scraping assembly 100 can enter the base station, and the main body or the scraping portion 32 can abut against an abutment within the base station, driving the main body and scraping portion 32 toward the cleaning member 20. This gradually reduces the dirt-receiving space formed between the main body, scraping portion 32, and cleaning member 20.
[0051] Because the surfaces of the main body and the scraping portion 32 are completely in contact with the surface of the cleaning member 20 , a single rotation of the cleaning member 20 can absorb more dirt from the scraping member 30 , thereby achieving self-cleaning of the scraping member 30 and further improving the self-cleaning efficiency of the scraping member 30 .
[0052] In some embodiments, as Figure 1 As shown, an elastic member 33 is provided at the connection between the main body and the scraping portion 32. One end of the elastic member 33 can be connected to the main body, and the other end of the elastic member 33 can be connected to the scraping portion 32.
[0053] When the scraping assembly 100 is in the self-cleaning state, the main body, scraping portion 32, and elastic member 33 can all abut against the cleaning member 20 under the action of an external force. When the external force is removed, for example, the self-cleaning of the scraping portion 32 is complete, and the main body and scraping portion 32 return to their original positions driven by the elastic member 33. In this way, the elastic member 33 allows the main body and scraping portion 32 to switch between different states, simplifying the method for resetting the main body and scraping portion 32.
[0054] In some examples, such as Figure 1 As shown, a rotating shaft is also provided at the connection. The elastic member 33 can be a torsion spring, which is mounted on the rotating shaft. One end of the torsion spring can be connected to the main body, and the other end can be connected to the scraping portion 32. Under the action of an external force, the main body and the scraping portion 32 overcome the elastic force of the torsion spring and approach the cleaning portion. The cleaning member 20 can then absorb and clean dirt on the scraping portion 32 and the main body. After the external force is removed, the main body and the scraping portion 32 can quickly return to their original position due to the restoring force of the torsion spring, thus entering the scraping state and scraping the cleaning member 20.
[0055] Since components such as torsion springs and rotating shafts are easily available, the direction of the torsion springs and rotating shafts is used to switch the main body and the scraping portion 32 between different states, which can further reduce the difficulty of switching the main body and the scraping portion 32 between different states.
[0056] In some embodiments, the surface of the scraping portion 32 may be covered with a barrier layer. The barrier layer may be located at the connection between the scraping portion 32 and the main body. The barrier layer may be formed by a coating process.
[0057] For example, when a dirt-receiving space is formed between the main body, the scraping portion 32, and the cleaning element 20, that is, when the scraping assembly 100 enters the scraping state, the barrier layer is located at the connection between the scraping portion 32 and the main body. Therefore, the barrier layer can reduce the probability of dirt remaining in the dirt-receiving space flowing out of the dirt-receiving space (e.g., to the cleaning element 20) through the connection, thereby improving the cleaning effect of the cleaning element 20.
[0058] In some embodiments, as Figure 1 As shown, the scraping assembly 100 may further include first abutment portions 34. In the axial direction of the cleaning member 20, the first abutment portions 34 are located on both sides of the scraping member 30. Under the influence of an external force, the first abutment portions 34 can drive the scraping member 30 toward the cleaning member 20 until the scraping member 30 is in a self-cleaning state and abuts against the surface of the cleaning member 20.
[0059] In this way, by providing the first abutting portions 34 on both sides of the scraping member 30 , more force points are applied to drive the scraping member 30 to move, thereby quickly driving the scraping member 30 to move.
[0060] In some embodiments, the free end of the scraping member 30 forms a bent portion 35. The bent portion 35 is recessed in a direction away from the cleaning member 20. For example, when the cleaning member 20 is cleaning, the bent portion 35 may abut against a portion of the surface of the cleaning member 20, leaving a space between the bent portion 35 and the cleaning member 20. Dirt on the surface of the cleaning member 20 can flow along the recessed direction of the bent portion 35, thereby entering the space and, in turn, the dirt holding space.
[0061] With such a configuration, the bent portion 35 can be used to contain the dirt, thereby reducing the probability of the dirt flowing out of the dirt containing space.
[0062] Secondly, some embodiments of the present application further provide a base station. This base station can be used in conjunction with the aforementioned scraping assembly 100. The base station can include a base. The base has a cavity defined therein and an opening that connects the cavity to the outside world. The scraping assembly 100 can enter the cavity through the opening for self-cleaning.
[0063] When the dirt scraping assembly 100 performs self-cleaning in the base station, a flushing assembly can also be provided in the base station. The flushing assembly cooperates with the dirt scraping assembly 100 to remove dirt on the surface of the cleaning member 20 from the cleaning member 20.
[0064] The above arrangement can utilize the base station to collect the dirt absorbed by the cleaning member 20 , thereby providing a cleaning space for the cleaning member 20 and the scraping member 30 .
[0065] In some embodiments, the inner wall of the cavity is provided with a second abutment (not shown). The scraping assembly 100 further includes a first abutment 34, which is located on either side of the scraping member 30 in the axial direction of the cleaning member 20. The first abutment 34 abuts against the second abutment to move the scraping member 30 of the scraping assembly 100 toward the cleaning member 20 of the scraping assembly 100.
[0066] In this way, the movement of the scraping member 30 is achieved by the matched first abutting portion 34 and the second abutting portion, which simplifies the method of pushing the scraping member 30 to move.
[0067] In addition, some embodiments of the present application further provide a cleaning robot. The cleaning robot includes the aforementioned scraping assembly 100. The cleaning robot includes the aforementioned scraping assembly 100. Thus, the sweeping robot has the functions and beneficial effects of the scraping assembly 100 provided in the aforementioned embodiments, which will not be further described here.
[0068] In some embodiments, the cleaning robot further includes a base station. The base station can be used in conjunction with the scraping assembly 100. The cleaning robot includes the base station. Thus, the sweeping robot has the functions and beneficial effects of the base station provided in the above embodiments, which will not be repeated here.
[0069] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.
[0070] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
