[0020] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0021] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0022] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0023] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0024] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0025] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when referring to an element being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element.

[0026] Welding fixtures typically include a pressure head assembly for clamping the workpiece and positioning it for welding. The pressure head assembly has an internal cavity, through which the workpiece can be welded during the welding process. For example, the internal cavity of the pressure head assembly can be a through-hole structure, allowing the emitted laser to pass through the hole to weld the workpiece. After use, the inner cavity and outer wall of the pressure head assembly accumulate significant amounts of welding fumes and slag. These fumes and slag can negatively impact the welding quality of subsequent welds or cycles. Therefore, the pressure head assembly needs to be cleaned promptly after each use or after a certain period of use.

[0027] Currently, cleaning of the pressure head assembly is generally done manually, such as by the operator using a brush or other cleaning tools to clean the outer surface and inner cavity of the pressure head assembly. However, manual cleaning is inefficient, labor-intensive, and makes it difficult to guarantee a high level of cleanliness for the pressure head assembly after cleaning.

[0028] Figure 1 This is a schematic diagram of the structure of the automatic cleaning device provided in an embodiment of this application from one perspective, as shown below. Figure 1 As shown in the figure, this application provides an automatic cleaning device, which includes a conveying component 1, a clamping component 4, a first driving system 3, a first cleaning component 6, and a second driving system 5.

[0029] The conveying component 1 is used to convey the fixture 100 to be cleaned. The conveying component 1 has a pause position W1, and the conveying component 1 can convey the fixture 100 to be cleaned to the pause position W1. The fixture 100 to be cleaned can be the aforementioned fixture with a pressure head assembly. In some other embodiments, the fixture 100 to be cleaned can also be other types of fixtures.

[0030] The first drive system 3 can be connected to the clamping component 4 and can be used to drive the clamping component 4 to move. For example, the first drive system 3 can drive the clamping component 4 to move between the pause position W1 and the cleaning position W2 so that the fixture 100 to be cleaned can be moved from the pause position W1 to the cleaning position W2 for cleaning through the clamping component 4. After the fixture 100 is cleaned, the cleaned fixture 100 can be moved back from the cleaning position W2 to the pause position W1, and the cleaned fixture 100 can be conveyed backward through the conveying component 1.

[0031] The first cleaning component 6 is spaced apart on one side of the conveying component 1. The second drive system 5 is connected to the first cleaning component 6 and can be used to drive the first cleaning component 6 to move in order to clean the fixture 100 located at the cleaning position W2. The second drive system 5 can drive the first cleaning component 6 to move in multiple directions, so as to control the first cleaning component 6 to move downward to clean the outer surface and inner cavity 1202 of the fixture 100.

[0032] Therefore, the cleaning equipment provided in this application embodiment can achieve automated cleaning of the fixture 100 without manual cleaning, saving labor costs, while improving cleaning efficiency and ensuring that the fixture 100 has a high degree of cleanliness after cleaning.

[0033] like Figure 1 As shown, the automatic cleaning equipment includes a platform 2 and a support frame 13. The support frame 13 is located on one side of the platform 2 and has the aforementioned pause position W1. The platform 2 has the aforementioned cleaning position W2. Structures such as the first drive system 3, the second drive system 5, the clamping assembly 4, and the first cleaning assembly 6 can all be installed on the platform 2. The platform 2 can reliably support numerous structures.

[0034] like Figure 1 As shown, the conveying assembly 1 consists of two sets, which are spaced apart from each other on the support frame 13. The conveying assembly 1 also includes a chain 12 and a drive motor 11. The chain 12 can form a closed loop on the support frame 13. The drive motor 11 is located at one end of the support frame 13 and can drive the chain 12 to transmit power, enabling the chain 12 to transfer power to the fixture 100.

[0035] Figure 2 for Figure 1 The enlarged view at point A, as shown Figure 2As shown, the chain 12 may include multiple sprocket assemblies 121 and two sets of chain plates disposed on the support frame 13. Each set of chain plates includes multiple first connecting plates 122 and multiple second connecting plates 123 disposed on the support frame 13. The multiple first connecting plates 122 and multiple second connecting plates 123 are interconnected to form a ring. Specifically, two adjacent first connecting plates 122 are connected through second connecting plates 123. The sprocket assemblies 121 support and transmit the fixture 100. The left and right sides of each sprocket assembly 121 are respectively connected to the connection points of the first connecting plates 122 and a second connecting plate 123 of the two sets of chain plates. The drive motor 11 drives the sprocket assemblies 121 to rotate. Thus, the multiple sprocket assemblies 121 can form a continuously transmitting chain 12 through the two sets of multiple first connecting plates 122 and second connecting plates 123, thereby realizing continuous transmission of the fixture 100.

[0036] Figure 3 An exploded view of the sprocket assembly 121 in the automatic cleaning equipment provided for implementation of this application, as shown below. Figure 3 As shown, the sprocket assembly 121 includes a drive roller 1211, two roller covers 1212, a rotating shaft 1213, and a bushing 1214. The diameter of the drive roller 1211 is larger than the diameter of the roller cover 1212. The two roller covers 1212 are fixedly installed on both sides of the drive roller 1211, and the drive roller 1211 and roller covers 1212 are fixedly sleeved on the bushing 1214. The drive roller 1211, roller covers 1212, and bushing 1214 are relatively fixed and can rotate synchronously relative to the rotating shaft 1213. The bushing 1214 is rotatably sleeved on the rotating shaft 1213. Both ends of the rotating shaft 1213 pass through the connection points between the second connecting plate 123 and the first connecting plate 122 of the two sets of chain plates. Since the diameter of the transmission roller 1211 is larger than the diameter of the roller cover 1212, the transmission roller 1211 can contact the fixture 100 for transmitting the fixture 100. The roller cover 1212 has a protrusion, and the drive motor 11 can drive each sprocket assembly 121 to move by cooperating with the protrusion of the roller cover 1212, so that the chain 12 can be continuously transmitted as a whole.

[0037] In this embodiment, the transmission roller 1211, roller cover 1212, bushing 1214 and rotating shaft 1213 can be assembled separately, which facilitates the replacement of any component among the transmission roller 1211, roller cover 1212, bushing 1214 and rotating shaft 1213. This facilitates individual maintenance of each sprocket assembly 121 and allows for flexible adjustment of the size and specifications of each component in the sprocket assembly 121 according to actual conditions, without the need to disassemble and replace the entire chain 12.

[0038] The transmission roller 1211 may be provided with a mounting groove, and at least a portion of the roller cover 1212 may be fixedly embedded in the mounting groove of the transmission roller 1211. The transmission roller 1211 and the roller cover 1212 may be fixed to the bushing 1214 by an interference fit.

[0039] like Figure 2 As shown, a drive gear 112 is provided on the drive shaft 111 of the drive motor 11. The drive gear 112 can mesh with the protrusion of the roller cover 1212. When the drive motor 11 drives the drive gear 112 to rotate through the drive shaft 111, the drive gear 112 can push the roller cover 1212 to drive the corresponding sprocket assembly 121 backward as a whole, thereby realizing the overall transmission of the chain 12.

[0040] like Figure 2 As shown, the automatic cleaning equipment also includes two sets of guide sections 21, which are spaced apart on the support frame 13 and extend along the transmission direction of the fixture 100. A space for transmitting the fixture 100 is provided between the two guide sections 21, and two sets of transmission assemblies 1 are disposed between the two guide sections 21. The fixture 100 can be placed on the sprocket assembly 121 and transmitted between the two guide sections 21. The guide sections 21 can accommodate rotation or offset of the fixture 100 during transmission, ensuring the consistency of the fixture 100's posture during transmission.

[0041] In order to reduce the sliding friction resistance between the guide part 21 and the fixture 100 and improve the transmission efficiency, a rolling element 24 can be provided on the guide part 21. The rolling element 24 can roll when it contacts the side of the fixture 100. Thus, rolling friction can be formed between the rolling element 24 and the fixture 100, which can ensure stable transmission of the fixture 100.

[0042] In one embodiment, the rolling element 24 can be a rotary bearing, with its rolling surface protruding from the inner surface of the guide portion 21. The inner surface of the guide portion 21 is the surface of the two guide portions 21 that are close to each other on one side. Thus, during the transfer of the fixture 100, the side of the fixture 100 can contact the rolling surface of the rotary bearing, and the rotary bearing can rotate during contact with the fixture 100, thereby improving transmission efficiency.

[0043] In some other embodiments, the rolling element 24 may also be a ball bearing or the like, and this embodiment does not limit this.

[0044] Figure 4 This is a partial schematic diagram of an automatic cleaning device provided in one embodiment of this application, as shown below. Figure 4As shown, the automatic cleaning equipment also includes a lifting assembly 22 and a positioning assembly 23, which are mounted on the platform 2 and located at the aforementioned pause position W1. When the fixture 100 to be cleaned is transported to the pause position W1 via the conveying assembly 1, the fixture 100 can be positioned above the lifting assembly 22. At this time, the lifting assembly 22 can be controlled to lift the fixture 100 to a certain height so that the fixture 100 can be positioned by the positioning assembly 23, thereby facilitating the clamping assembly 4 to move the fixture 100 to the cleaning position W2.

[0045] In one embodiment, such as Figure 4 As shown, the lifting assembly 22 includes a lifting cylinder 221 and a support plate 222. The cylinder body of the lifting cylinder 221 can be installed and fixed on the support frame 13. The cylinder rod of the lifting cylinder 221 can be connected to the support plate 222. The support plate 222 can be used to support the fixture 100. When the cylinder rod extends, the fixture 100 can be lifted to a preset height through the support plate 222.

[0046] Figure 5 This is a partial front view of the automatic cleaning device provided in an embodiment of this application, such as... Figure 5 As shown, the positioning component 23 may include two sets of brackets 234, a positioning cylinder 231, a connecting block 232, and a positioning pin 233. The cylinder body of the positioning cylinder 231 is mounted on the bracket 234. The two sets of brackets 234 can be vertically fixed on both sides of the support frame 13, and the brackets 234 can position the positioning cylinder 231 at a set height relative to the conveying component 1. The two ends of the connecting block 232 are respectively connected to the cylinder rod of the positioning cylinder 231 and the positioning pin 233. The side of the fixture 100 may be provided with a positioning hole. When the fixture 100 is lifted to the preset height, the cylinder rod of the positioning cylinder 231 extends, allowing the positioning pin 233 on the connecting block 232 to be inserted into the positioning hole on the fixture 100, thereby achieving the positioning of the fixture 100.

[0047] Figure 6 This is a partial schematic diagram of an automatic cleaning device provided in another embodiment of this application, as shown below. Figure 6 As shown, the clamping assembly 4 includes two first cylinders 41, two sets of connecting rod assemblies 42, and two grippers 43. The first cylinders 41 are connected to the grippers 43 via the connecting rod assemblies 42 and are used to drive the grippers 43 to rotate, thereby clamping the fixture 100. One first cylinder 41, one connecting rod assembly 42, and one gripper 43 can constitute a clamping unit. Two such clamping units can be provided, located on opposite sides of the fixture 100 to be clamped. Driven by the first drive system 3, the two grippers 43 can be moved closer or further apart, thereby achieving clamping or releasing of the fixture 100. The structure is simple and the clamping is reliable.

[0048] like Figure 6 As shown, the first drive system 3 may include a first motor 31, a first support member 32, and a first slider 33. The first support member 32 may be fixedly connected to the platform 2. The first motor 31 may be mounted on the first support member 32. The first slider 33 may be slidably connected to the first support member 32. The clamping assembly 4 may be connected to the first slider 33. A transmission mechanism may be provided inside the first support member 32. The first motor 31 may be connected to the first slider 33 through the transmission mechanism, so as to control the sliding of the first slider 33 relative to the first support member 32 through the transmission mechanism, thereby driving the clamping assembly 4 to move between the pause position W1 and the cleaning position W2.

[0049] like Figure 6 As shown, the clamping assembly 4 also includes a fixing plate 44. The cylinder body of the first cylinder 41 is fixed to the fixing plate 44. The fixing plate 44 can be connected to the first slider 33, and the first slider 33 can drive the fixing plate 44 to move synchronously. The connecting rod assembly 42 and the first cylinder 41 can be connected to the fixing plate 44. The fixing plate 44, the connecting rod assembly 42, and the first cylinder 41 can form an integral structure and can be installed as a whole on the first slider 33, thereby facilitating assembly.

[0050] Figure 7 This is a front view of the gripper 43 assembly cooperating with the first drive system 3 in the automatic cleaning device provided in the embodiments of this application, as shown below. Figure 7 As shown, the connecting rod assembly 42 includes a first connecting rod 421, a second connecting rod 422, and a third connecting rod 423. One end of the first connecting rod 421 is fixed to the fixing plate 44, and the end of the first connecting rod 421 away from the fixing plate 44 is hinged to the gripper 43. One end of the second connecting rod 422 is hinged to the gripper 43. The first end of the third connecting rod 423 is hinged to the end of the second connecting rod 422 away from the gripper 43, the second end of the third connecting rod 423 is hinged to the first connecting rod 421, and the third end of the third connecting rod 423 is hinged to the cylinder connecting rod of the first cylinder 41.

[0051] The device includes two first cylinders 41, which can move synchronously. When the cylinder rods of the two first cylinders 41 extend, the two grippers 43 move closer together through the linkage of the first connecting rod 421, the second connecting rod 422, and the third connecting rod 423. This allows the grippers 43 to hold the fixture 100 and move it. When the cylinders of the two first cylinders 41 retract, the two grippers 43 move away from each other, thus releasing the fixture 100.

[0052] Figure 8 This is a schematic diagram of the structure of the fixture 100 provided in the embodiments of this application, as shown below. Figure 8As shown, the fixture 100 can be used to press and position the cover plate and camera module in electronic devices such as mobile phones. The fixture 100 may include a first pressure cover 110 and a second pressure cover 120. The first pressure cover 110 is used to press and position the cover plate of the electronic device, and the second pressure cover 120 is used to press and position the camera module of the electronic device to ensure the welding quality of the camera module and other corresponding components.

[0053] The second pressure cap 120 and the first pressure cap 110 are detachably connected.

[0054] Figure 9 This is a schematic diagram of the structure of the second pressure cap 120 in the jig 100 provided in the embodiments of this application from one perspective, as shown below. Figure 9 As shown, the second pressure cap 120 is provided with the aforementioned inner cavity 1202. After welding operations, welding fumes and slag easily accumulate in the inner cavity 1202 and on the outer surface of the second pressure cap 120. Therefore, the second pressure cap 120 requires cleaning. By assembling the second pressure cap 120 and the first pressure cap 110 separately, the second pressure cap 120 can be easily disassembled for independent cleaning.

[0055] like Figure 9 As shown, the second pressure cap 120 includes a clamping part and a housing 1203, with the clamping part being telescopically connected to the housing 1203. Figure 10 This is a schematic diagram of the second pressure cap 120 in the fixture 100 provided in the embodiments of this application from another perspective. Figure 11 This is a schematic diagram of the structure of the first pressure cap 110 in the fixture 100 provided in the embodiments of this application, as shown below. Figure 10 and Figure 11 As shown, the clamping part is provided with a claw 1201a, and the first pressure cover 110 is provided with a first locking hole 1101. The claw 1201a can engage with the first locking hole 1101, thereby ensuring the reliability of the assembly of the first pressure cover 110 and the second pressure cover 120. For example, the claw 1201a includes a hook portion, which can engage with the first pressure cover 110 at a position adjacent to the edge of the first locking hole 1101.

[0056] The housing 1203 is provided with a sliding hole 1203a. In the direction of extension and retraction of the clamping part relative to the housing 1203, the length of the sliding hole 1203a is greater than the thickness of the claw 1201a, so that the claw 1201a can move in the sliding hole 1203a. There can be two clamping parts, respectively located on opposite sides of the housing 1203. The two clamping parts can correspond one-to-one with the claws 43 on the clamping assembly 4. When the two clamping parts are not subjected to the clamping force of the claws 43, the claws 1201a can be engaged in the first locking hole 1101 on the first pressure cover 110. When the claws 43 apply clamping force to the corresponding clamping parts, the two clamping parts can move closer to each other, and the claws 1201a do not engage with the portion of the first pressure cover 110 located around the first locking hole 1101. The claws 1201a can be removed from the first locking hole 1101, thereby enabling the disassembly of the second pressure cover 120. In the direction of extension and retraction of the two clamping parts, the length of the first clamping hole 1101 is also greater than the thickness of the clamping claw 1201a, which facilitates the insertion or removal of the clamping claw 1201a.

[0057] In order for the clamping part to automatically reset when the clamping force applied to it is removed, an elastic element such as a spring or a sheet can be provided between the clamping part and the housing 1203. The elastic element can provide an elastic force for the clamping part to automatically reset.

[0058] like Figure 6 As shown, a base 25 is provided at the cleaning position. Figure 12 This is a schematic diagram of the structure of the base 25 in the automatic cleaning device provided in the embodiments of this application, as shown below. Figure 12 As shown, a second locking hole 251 can be provided on the base 25. This second locking hole 251 has the same or similar structure as the first locking hole 1101 on the first cover 110. The locking method of the claw 1201a on the second cover 120 in the first opening is the same as the locking method in the second locking hole 251. After the clamping assembly 4 removes the second cover 120 to be cleaned from the first cover 110 on the conveying assembly 1, it can move to the cleaning position W2 and can lock the second cover 120 to be cleaned into the second locking hole 251 on the base 25 through the claw 1201a, so as to fix the second cover 120 to be cleaned and the base 25, thereby ensuring the stability of the second cover 120 to be cleaned during the cleaning process.

[0059] Figure 13 This is a schematic diagram of the structure of the first cleaning component 6 provided in an embodiment of this application. Figure 14 for Figure 13 A partial schematic diagram, such as Figure 13 and Figure 14As shown, the first cleaning assembly 6 includes a main shaft 61 and a secondary shaft 62. One end of the main shaft 61 is connected to the second drive system 5, and the other end of the main shaft 61 is in transmission cooperation with the secondary shaft 62. A first cleaning head 63 is provided on the end of the secondary shaft 62 away from the main shaft 61. When the second drive system 5 controls the main shaft 61 to rotate, the main shaft 61 can drive the secondary shaft 62 to rotate. The second drive system 5 can also drive the first cleaning assembly 6 to move in multiple directions, so that the secondary shaft 62 can drive the first cleaning head 63 to enter the inner cavity 1202 of the second pressure cover 120. The secondary shaft 62 can drive the first cleaning head 63 to rotate in the inner cavity 1202, thereby achieving cleaning of the inner cavity 1202. The first cleaning head 63 can be a brush, a flexible cloth, etc.

[0060] like Figure 14 As shown, a drive wheel 611 is provided at the end of the main shaft 61 away from the second drive system 5, and a driven wheel 621 is provided at the end of the secondary shaft 62 away from the first cleaning head 63. The driven wheel 621 meshes with the drive wheel 611. When the second drive system 5 controls the main shaft 61 to rotate, the main shaft 61 can drive the drive wheel 611 to rotate synchronously. Through the meshing action of the drive wheel 611 and the driven wheel 621, the secondary shaft 62 can be driven to rotate synchronously. The rotation direction of the secondary shaft 62 is opposite to the rotation direction of the main shaft 61. Thus, the secondary shaft 62 can drive the first cleaning head 63 to rotate synchronously, thereby cleaning the inner cavity 1202 of the second pressure cover 120.

[0061] The inner cavity 1202 of the second pressure cap 120 can be provided with one, two, three or more. Figure 9 The second pressure cap 120 shown has three inner cavities 1202. The number of secondary shafts 62 can be the same as the number of inner cavities 1202, so that each inner cavity 1202 can be cleaned by a corresponding secondary shaft 62 and the first cleaning head 63.

[0062] Figure 15 This is a partial schematic diagram of an automatic cleaning device provided in another embodiment of this application, as shown below. Figure 15As shown, the second drive system 5 includes a first drive component 51, a second drive component 52, a third drive component 53, and a fourth drive component 54. The first drive component 51 is connected to the second drive component 52 and is used to drive the second drive component 52 to move along a first direction X. The second drive component 52 is connected to the third drive component 53 and is used to drive the third drive component 53 to move along a second direction Y. The third drive component 53 is connected to the fourth drive component 54 and the first cleaning component 6, and is used to drive the third drive component 53 and the first cleaning component 6 to move along a third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other. In this embodiment, the first direction X is parallel to the direction of the conveying fixture 100 of the conveying component 1, and the first direction X is also parallel to the moving direction of the gripper 43 component, that is, the first direction X is parallel to the direction from the pause position W1 to the cleaning position W2, and the third direction Z is parallel to the height direction of the automatic cleaning device. The fourth drive component 54 is connected to the first cleaning component 6 and is used to drive the main shaft 61 of the first cleaning component 6 to rotate.

[0063] In this embodiment, the first driving component 51, the second driving component 52 and the third driving component 53 cooperate to drive the first cleaning component 6 to move in three different directions, thereby enabling the first cleaning component 6 to clean the inner cavity 1202 and the surface of the fixture 100.

[0064] In one embodiment, the first driving component 51, the second driving component 52, and the third driving component 53 have similar structures. Exemplarily, each of the three components may include a motor, a transmission component, and a slider. The transmission component may include components such as a lead screw. The motor controls the movement of the slider via the transmission component, and the slider can be connected to the component to be driven. Exemplarily, the slider in the first driving component 51 can be connected to the second driving component 52. Thus, the motor in the first driving component 51 can control the slider to move along the first direction X via the transmission component, thereby driving the second driving component 52 to move as a whole along the first direction X. The driving principles of the second driving component 52 and the third driving component 53 are similar to those of the first driving component 51, and will not be described further here.

[0065] Figure 16 This is a schematic diagram of the structure of the automatic cleaning device provided in the embodiments of this application, showing the cooperation between the first cleaning component 6 and the fourth driving component 54. Figure 16As shown, a first transmission wheel 612 is provided at the end of the main shaft 61 away from the driving wheel 611. The fourth drive assembly 54 includes a second transmission wheel 541. The first transmission wheel 612 and the second transmission wheel 541 are connected by a synchronous belt 542. The fourth drive assembly 54 can be a motor, which can drive the second transmission wheel 541 to rotate. Through synchronous transmission, the first transmission wheel 612 can rotate synchronously, thereby controlling the main shaft 61 to drive. The main shaft 61 can drive the secondary shaft 62 and the first cleaning head 63 to rotate through the cooperation of the driving wheel 611 and the driven wheel 621. Thus, the first cleaning head 63 can be used to clean the inner cavity 1202 of the fixture 100.

[0066] Figure 17 This is a partial schematic diagram of an automatic cleaning device provided in another embodiment of this application, as shown below. Figure 17 As shown, the automatic cleaning device also includes a second cleaning component, which is mounted on the stand 2 below the cleaning position W2. The second cleaning component includes a second cylinder 71, a gear worm 72, a rotating gear 73, a gear seat 74, and a second cleaning head 75. The second cylinder 71 is connected to the gear worm 72 and drives the gear worm 72 to reciprocate. The rotating gear 73 is rotatably connected to the gear seat 74 and meshes with the gear worm 72. The second cleaning head 75 is located below the cleaning position W2 and is connected to the rotating gear 73. It is used to clean the bottom of the fixture 100. In this embodiment, the bottom of the second pressure cap 120 can be cleaned using the second cleaning head 75. The second cleaning head 75 can be a brush or a flexible cloth, etc.

[0067] Specifically, when the second cylinder 71 drives the worm gear 112 to reciprocate, the worm gear 72 meshes with the rotating gear 73, causing the rotating gear 73 to rotate clockwise or counterclockwise. This, in turn, drives the second cleaning head 75 to rotate reciprocally, allowing the second cleaning head 75 to clean the bottom of the second cover 120. Thus, through the cooperation of the first cleaning component 6 and the second cleaning component, comprehensive cleaning of all surfaces and the inner cavity 1202 of the second cover 120 can be achieved, ensuring a high degree of cleanliness after cleaning the second cover 120.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
