[0002] With the advancement of science and technology and the development of society, cleaning systems for automatic cleaning, such as sweeping robots and floor scrubbers, have gradually entered people's lives. With the development of natural language processing technology, cleaning systems with voice control functions have gradually emerged. Cleaning systems with voice control functions can automatically recognize the voice commands spoken by the user, and then respond to the recognition results of the voice commands and perform corresponding operations.

[0003] However, the cleaning system generates significant noise when in operation. The user's voice is drowned out by the machine's operating noise, resulting in an extremely low signal-to-noise ratio, which seriously affects the accuracy of voice recognition and even often causes the voice command to fail to be recognized. Summary of the invention

[0004] In order to solve the technical problem of low voice recognition accuracy of current cleaning systems, the present application provides a cleaning system.

[0005] In a first aspect of the present application, a cleaning system is provided, comprising: a protective member, the cover of which is arranged outside the ranging member; a supporting member, connected to the protective member; a circuit board, arranged on the supporting member and located between the supporting member and the protective member, and a sound receiving module is provided on the circuit board.

[0006] In some embodiments, the protective member includes: a supporting portion connected to the supporting member and spaced apart from the supporting member; a protective portion connected to the supporting portion; wherein the circuit board is disposed between the supporting portion and the supporting member.

[0007] In some embodiments, a sound receiving hole is formed on the support portion, the circuit board is spaced apart from the support portion, and the sound receiving module is disposed opposite to the sound receiving hole.

[0008] In some embodiments, a sealing member is provided between the circuit board and the supporting portion, the sealing member defines a channel connecting the sound receiving hole and the sound receiving module, and the sealing member is in contact with the supporting portion and the sound receiving module.

[0009] In some embodiments, a first wire-holding groove is formed on the inner wall of the protective member, and the cleaning system further comprises: a voice control wire, which passes through the first wire-holding groove and is electrically connected to the circuit board.

[0010] In some embodiments, the cleaning system also includes a pivot bracket connected to the protective member; a second wire slot connected to the first wire slot is opened on the pivot bracket, and the voice control line is passed through the second wire slot and the first wire slot and is electrically connected to the circuit board.

[0011] In some embodiments, a projection of the second wire clamping groove along the axial direction of the protection member at least partially overlaps with the support member.

[0012] In some embodiments, the cleaning system also includes a shell for supporting the rotating shaft bracket and the protective member; a wire groove connected to the second wire clamping groove is opened on the shell, and the speech control line is passed through the wire groove, the second wire clamping groove and the first wire clamping groove and is electrically connected to the circuit board; wherein the projection of the protective member on the shell overlaps with the wire groove.

[0013] In some embodiments, a through hole communicating with the first wire clamping slot is formed on the support member, and the speech control line passes through the first wire clamping slot and the through hole to be electrically connected to the circuit board.

[0014] In some embodiments, the cleaning system further includes: a main control board, which is disposed in the housing and electrically connected to the voice control line.

[0015] In some embodiments, the shell includes an upper shell and a lower shell connected to the upper shell, the protective component is disposed on the upper shell, and the distance measuring component is disposed on the upper shell or the lower shell.

[0016] The cleaning system provided according to one or more embodiments of the present application has at least the following technical effects:

[0017] Since the cleaning system needs to run automatically, and there are often various obstacles or obstructions in the cleaning environment, the distance measuring device arranged in the protective device is used to identify objects and detect obstacles in front of the cleaning system. In order to improve the accuracy of the path automatically planned by the cleaning system, the protective device is located on the top of the main unit of the cleaning system and away from the main unit of the cleaning system to avoid the distance measuring device being blocked by the main unit of the cleaning system, thereby ensuring that the distance measuring device can accurately obtain the actual situation on site.

[0018] Since the circuit board and the distance measuring component are both arranged in the protective component, that is to say, the circuit board will also be away from the main unit of the cleaning system, so as to reduce the interference of the working noise of the main unit of the cleaning system on the voice commands spoken by the user, thereby improving the accuracy of the sound receiving module on the circuit board in collecting the voice commands spoken by the user.

[0019] Since the support member is connected to the protective member, and the circuit board is connected to the support member and is located between the support member and the protective member, the circuit board is protected by the support member and the protective member, thereby avoiding collision between the circuit board and external debris, and avoiding external impurities (such as dust, water, etc.) from falling onto the circuit board, thereby ensuring the safety of the circuit board. At the same time, it also avoids the circuit board from being exposed to the outside, thereby ensuring the beauty of the entire cleaning system. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0033] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 In a first aspect of the present application, a cleaning system is provided, including: a protective member 10, a supporting member 20 and a circuit board 30. The protective member 10 is covered outside the distance measuring member. The supporting member 20 is connected to the protective member 10. The circuit board 30 is connected to the supporting member 20 and is located between the supporting member 20 and the protective member 10, and a sound receiving module 40 is provided on the circuit board 30.

[0034] The cleaning system may be an automatic floor scrubber, a sweeping robot, an automatic sweeper, etc., and the embodiments of the present application are not limited thereto.

[0035] The distance measuring component can be a laser radar detection component.

[0036] Since the cleaning system needs to run automatically, and there are often various obstacles or obstructions in the cleaning environment, the distance measuring component provided in the protective component 10 is used to identify objects and detect obstacles in front of the cleaning system. In order to improve the accuracy of the path automatically planned by the cleaning system, the protective component 10 is located on the top of the main unit of the cleaning system and away from the main unit of the cleaning system to avoid the distance measuring component being blocked by the main unit of the cleaning system, thereby ensuring that the distance measuring component can accurately obtain the actual situation on site.

[0037] Since the circuit board 30 and the distance measuring component are both arranged in the protective component 10, that is to say, the circuit board 30 will also be away from the main unit of the cleaning system to reduce the interference of the main unit working noise of the cleaning system on the voice commands spoken by the user, thereby improving the accuracy of the sound receiving module 40 on the circuit board 30 in collecting the voice commands spoken by the user.

[0038] Since the circuit board 30 is connected to the support member 20 and is located between the support member 20 and the protective member 10, the support member 20 and the protective member 10 protect the circuit board 30, thereby preventing the circuit board 30 from colliding with external debris and preventing external impurities (such as dust, water, etc.) from falling onto the circuit board 30, thereby ensuring the safety of the circuit board 30. At the same time, it also prevents the circuit board 30 from being exposed to the outside, thereby ensuring the beauty of the entire cleaning system.

[0039] In some embodiments, when the circuit board 30 is to be installed, the circuit board 30 can be installed on the support member 20 , and then the support member 20 is connected to the protective member 10 to facilitate the installation of the circuit board 30 .

[0040] In some embodiments, in order to facilitate the assembly and disassembly of the circuit board 30 on the support member 20, the circuit board 30 can be connected to the support member 20 by bolts. Of course, in some other embodiments, the circuit board 30 can also be connected to the support member 20 by buckles. This application embodiment is not limited.

[0041] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In some embodiments, in order to protect the circuit board 30, the protection member 10 includes: a support portion 101 and a protection portion 102. The support portion 101 is connected to the support member 20 and is spaced apart from the support member 20. The protection portion 102 is connected to the support portion 101. The circuit board 30 is disposed between the support portion 101 and the support member 20.

[0042] In some embodiments, the support portion 101 is the top of the protective member 10, that is, the support portion 101 is the component farthest from the protective member 10 and the main unit of the cleaning system. The circuit board 30 is arranged between the support portion 101 and the support member 20, so that the circuit board 30 is as far away from the main unit of the cleaning system as possible, so as to reduce the interference of the working noise of the main unit of the cleaning system on the voice commands spoken by the user, thereby improving the accuracy of the sound receiving module 40 on the circuit board 30 in collecting the voice commands spoken by the user.

[0043] In some embodiments, the circuit board 30 is disposed in the protection portion 102 and between the support portion 101 and the support member 20. The circuit board 30 is shielded by the protection portion 102, the support portion 101 and the support member 20 to protect the circuit board 30, avoid collision between the circuit board 30 and external debris, avoid external impurities (such as dust, water, etc.) from falling onto the circuit board 30, ensure the safety of the circuit board 30, and at the same time, avoid exposure of the circuit board 30 to the outside, ensure the beauty of the cleaning system as a whole.

[0044] In some embodiments, in order to ensure the stability of the connection between the support portion 101 and the protection portion 102 and to reduce the processing cost, the support portion 101 and the protection portion 102 can be integrally formed.

[0045] See also Figure 4 In some embodiments, the protection portion 102 has an opening 104 , and the opening 104 is opposite to the support portion 101 . After the circuit board 30 is mounted on the support member 20 , the support member 20 passes through the opening 104 and enters the protection portion 102 .

[0046] In some embodiments, in order to facilitate the disassembly and assembly of the support member 20 on the support portion 101, the support member 20 can be connected to the support portion 101 by bolts. Of course, in some other embodiments, the support member 20 can also be connected to the support portion 101 by buckles. This application embodiment is not limited.

[0047] In some embodiments, the protection portion 102 is connected to an edge of the support portion 101 , so that the support member 20 , the protection portion 102 , and the support portion 101 can fully accommodate the circuit board 30 .

[0048] In some embodiments, along the axial direction of the protection member 10 , the cross-sectional shapes of the protection portion 102 and the support portion 101 may both be circular, so that the support member 20 , the protection portion 102 , and the support portion 101 can fully accommodate the circuit board 30 .

[0049] In some embodiments, the diameter of the support member 20 matches the inner diameter of the protective portion 102, that is, the edge of the support member 20 can fit into the protective portion 102, which can prevent external impurities (such as dust, water, etc.) from entering and reaching the circuit board 30, further ensuring the safety of the circuit board 30.

[0050] See also Figure 2 , Figure 3 and Figure 8In some embodiments, in order to enable the sound receiving module 40 on the circuit board 30 to receive the voice command spoken by the user, a plurality of sound receiving holes 103 are provided on the support portion 101, the circuit board 30 and the support portion 101 are spaced apart, and a plurality of sound receiving modules 40 are provided on the circuit board 30, and the sound receiving modules 40 are arranged opposite to the sound receiving holes 103. The sound receiving holes 103 are through holes penetrating the support portion 101, and the sound receiving modules 40 may be mics (microphones).

[0051] In some embodiments, when the user speaks a voice command, the voice command can reach the sound receiving module 40 through the sound receiving hole 103. The sound receiving module 40 is electrically connected to the main control board. The sound receiving module 40 sends the voice command to the main control board, and the main control board controls the action of the cleaning system according to the voice command.

[0052] In some embodiments, the support portion 101 is the top of the protective member 10, that is, the support portion 101 is the component that is farthest from the protective member 10 and the main unit of the cleaning system. The sound receiving hole 103 is opened on the support portion 101 so that the sound receiving hole 103 is as far away from the main unit of the cleaning system as possible, so as to reduce the interference of the working noise of the main unit of the cleaning system on the voice commands spoken by the user, thereby improving the accuracy of the sound receiving module 40 on the circuit board 30 in collecting the voice commands spoken by the user.

[0053] In some embodiments, in order to fully collect the voice commands spoken by the user, the number of sound receiving holes 103 can be multiple, and the number of sound receiving modules 40 can also be multiple. The multiple sound receiving holes 103 correspond one-to-one to the multiple sound receiving modules 40, so that the sound receiving modules 40 can collect the voice commands spoken by the user through the corresponding sound receiving holes 103.

[0054] In some embodiments, in order to further fully collect the voice commands spoken by the user, a plurality of sound receiving holes 103 can be opened on the support portion 101 at evenly spaced angles, so that the sound receiving holes 103 can collect the voice commands spoken by the user from all directions, thereby improving the accuracy of the sound receiving module 40 on the circuit board 30 in collecting the voice commands spoken by the user.

[0055] See also Figure 2 , Figure 3 and Figure 8 In some embodiments, in order to ensure the safety of the circuit board 30, a sealing member 50 is provided between the circuit board 30 and the support portion 101, and the sealing member 50 is provided with a channel connecting the sound receiving hole 103 and the sound receiving module 40, and the sealing member 50 is in contact with the support portion 101 and the sound receiving module 40. The sealing member 50 may be a sealing ring, and the material of the sealing member 50 may be a waterproof and breathable film foam.

[0056] In some embodiments, since the sound receiving hole 103 needs to transmit the voice commands spoken by the user to the sound receiving module 40, the sound receiving hole 103 is a through hole that penetrates the support portion 101. In order to prevent external impurities from falling onto the circuit board 30 through the sound receiving hole 103, a seal 50 is provided between the circuit board 30 and the support portion 101. The voice commands spoken by the user pass through the sound receiving hole 103 and the channel to reach the sound receiving module 40 in turn. In other words, external impurities will only fall onto the sound receiving module 40 through the sound receiving hole 103 and the channel and will not fall onto the circuit board 30, thereby further ensuring the safety of the circuit board 30.

[0057] In some embodiments, since the seal 50 is in contact with the support portion 101 and the sound receiving module 40, there is no gap between the seal 50 and the support portion 101, and there is no gap between the seal 50 and the sound receiving module 40, which can further prevent external impurities from falling onto the circuit board 30, thereby ensuring the safety of the circuit board 30.

[0058] In some embodiments, when there are multiple sound receiving holes 103, there may be one seal 50, and multiple channels are provided on the seal 50, and the multiple channels correspond to the multiple sound receiving holes 103 one by one, and each channel connects the corresponding sound receiving hole 103 and the sound receiving module 40. Of course, in some other embodiments, there may be multiple seals 50, and the multiple seals 50 correspond to the multiple sound receiving holes 103 one by one, and each seal 50 has a channel connecting the corresponding sound receiving hole 103 and the sound receiving module 40.

[0059] In some embodiments, the channel is coaxially arranged with the sound receiving hole 103 to ensure that the voice commands spoken by the user are transmitted to the sound receiving module 40 in a timely and accurate manner.

[0060] See also Figure 5 and Figure 6 In some embodiments, in order to facilitate wiring, a first wire clamping groove 105 is provided on the inner wall of the protective member 10, and the cleaning system further includes: a speech control wire 60. The speech control wire 60 is passed through the first wire clamping groove 105 and is electrically connected to the circuit board 30. After the speech control wire 60 is electrically connected to the circuit board 30, the speech control wire 60 is guided through the first wire clamping groove 105 to facilitate the wiring of the speech control wire 60.

[0061] In some embodiments, the first wire slot 105 is located on the inner wall of the protective member 10, that is, the first wire slot 105 is not exposed outside the protective member 10, so that the speech control line 60 is also located inside the protective member 10. The speech control line 60 is not exposed, which can reduce the appearance line and ensure aesthetics.

[0062] See also Figure 5 and Figure 6In some embodiments, in order to facilitate wiring, the cleaning system further includes a shaft bracket 70 connected to the protective member 10. The shaft bracket 70 is provided with a second wire clamping slot 701 connected to the first wire clamping slot 105. The speech control line 60 is passed through the second wire clamping slot 701 and is electrically connected to the first wire clamping slot 105 and the circuit board 30. The speech control line 60 passing through the first wire clamping slot 105 is guided through the second wire clamping slot 701 to facilitate wiring of the speech control line 60.

[0063] In some embodiments, in order to reduce the appearance line, the projection of the second wire clamping groove 701 along the axial direction of the protective member 10 at least partially overlaps with the support member 20, that is, the second wire clamping groove 701 will be blocked by the main body of the pivot bracket 70, and the first wire clamping groove 105 is not exposed outside the pivot bracket 70, so that the speech control line 60 is also located inside the pivot bracket 70, and the speech control line 60 is not exposed, thereby ensuring the appearance.

[0064] In some embodiments, the protective member 10 can be connected to the pivot bracket 70 via a pivot, that is, the protective member 10 can perform a pitch movement. When the protective member 10 is pressed by an obstacle, the protective member 10 can move downward to reduce the pressure and facilitate the exit of the main unit of the cleaning system.

[0065] See also Figure 1 , Figure 5 , Figure 6 and Figure 7 In some embodiments, in order to facilitate wiring, the cleaning system further includes a housing 80 for supporting the shaft bracket 70 and the protective member 10. The housing 80 is provided with a wire groove 801 connected to the second wire groove 701. The speech control line 60 is passed through the wire groove 801, the second wire groove 701 and the first wire groove 105 and is electrically connected to the circuit board 30. The speech control line 60 passing through the second wire groove 701 is guided through the wire groove 801 to facilitate the wiring of the speech control line 60.

[0066] In some embodiments, a main control board is provided in the shell 80, and one end of the voice control line 60 is electrically connected to the circuit board 30, and the other end is electrically connected to the main control board, which is used to realize signal transmission between the circuit board 30 and the main control board to realize voice control of the cleaning system.

[0067] In some embodiments, in order to reduce the appearance line, the projection of the protective member 10 on the shell 80 overlaps with the wire groove 801. That is, the protective member 10 can be covered above the wire groove 801. The protective member 10 blocks the wire groove 801, so that the speech control line 60 is also blocked by the protective member 10, and the speech control line 60 is not exposed, thereby ensuring the appearance.

[0068] In some embodiments, in order to facilitate the installation of the shaft bracket 70, the shaft bracket 70 can be connected to the housing 80 by bolts.

[0069] See also Figure 5 In some embodiments, in order to facilitate wiring, a third wire clamping slot 702 connected to the second wire clamping slot 701 and the wire groove 801 is further provided on the pivot bracket 70. One end of the speech control line 60 is electrically connected to the circuit board 30, and the other end passes through the first wire clamping slot 105, the second wire clamping slot 901, the second wire clamping slot 902 and the wire groove 801 in sequence to be electrically connected to the circuit board connector to facilitate the wiring of the speech control line 60.

[0071] See also Figure 6 In some embodiments, in order to facilitate wiring, a through hole 201 connected to the first wire clamping groove 105 is opened on the support member 20, and the speech control line 60 passes through the first wire clamping groove 105 and the through hole 201 and is electrically connected to the circuit board 30 to facilitate the wiring of the speech control line 60.

[0072] In some embodiments, in order to reduce costs, the projection of the first wire clamping groove 105 along the axial direction of the protective member 10 at least partially overlaps with the through hole 201, that is, along the axial direction of the protective member 10, the first wire clamping groove 105 and the through hole 201 are located on the same vertical line. After the speech control line 60 passes through the through hole 201, it can directly enter the first wire clamping groove 105 to facilitate the routing of the speech control line 60 and reduce the length of the speech control line 60.

[0073] See also Figure 6 In some embodiments, in order to facilitate the installation of the support member 20, a positioning member 202 is provided on the support member 20, and a positioning groove 106 is provided on the protective member 10. The positioning member 202 can be embedded in the positioning groove 106 to achieve positioning of the support member 20, so as to facilitate the installation of the support member 20 in the protective member 10.
