[0012] In one of the embodiments, the base assembly further comprises a sensing member, the sensing member is used to sense the opening and closing of the upper cover assembly;

[0013] The driving member is in communication connection with the sensing member, and is configured to drive the movable cover to move to switch to the shielding state when the sensing member senses that the upper cover assembly is opened, and to drive the movable cover to move to switch to the stowed state when the sensing member senses that the upper cover assembly is closed.

[0014] In one of the embodiments, the sensing member is used to sense whether the upper cover assembly is within a set range, when the upper cover assembly is within the set range, the sensing member determines that the upper cover assembly is closed; when the upper cover assembly is not within the set range, the sensing member determines that the upper cover assembly is opened.

[0037] Please refer to Figures 1 to 4 An embodiment of the present application provides a cleaning machine 100, which comprises a base assembly 10 and an upper cover assembly 30. The base assembly 10 comprises a seat body 11 and a first conductive part 13 arranged on the seat body 11, and the first conductive part 13 is used to form an electrical connection with the upper cover assembly 30. The base assembly 10 further comprises a movable cover 15 movably arranged at the first conductive part 13 and having a shielding state and a retracted state switched by movement. The movable cover 15 is configured to shield the first conductive part 13 in the shielding state. The movable cover 15 is configured to expose the first conductive part 13 in the retracted state.

[0038] In an embodiment, the cleaning machine 10 can be an ultrasonic cleaning machine with ultrasonic cleaning function. It can be understood that, to realize its normal function, the base assembly 10 is formed with a cleaning cavity Q for containing cleaning liquid to clean articles. In addition, the base assembly 10 is also capable of forming ultrasonic waves to realize ultrasonic cleaning function and clean articles in the cleaning cavity Q. In other embodiments, the cleaning machine 10 can also be a spray cleaning machine, a stirring cleaning machine, etc.

[0039] The upper cover assembly 30 is capable of being closed or opened relative to the base assembly 10 and forms electrical connection with the base assembly 10 through the first conductive member 13 when closed. The closing and opening mode of the upper cover assembly 30 can be, but is not limited to, flip opening and closing. Specifically, the upper cover assembly 30 includes a cover body 31 and a second conductive member 33 arranged on the cover body 31. The cover body 31 is closed on the cavity opening of the cleaning cavity Q and is operable to be opened. The first conductive member 13 and the second conductive member 33 are configured to be in contact with each other to form electrical connection when the cover body 31 is closed on the cavity opening of the cleaning cavity Q. It can be understood that, to realize contact with the second conductive member 33, the first conductive member 13 is exposed at the cavity opening of the cover body 31 without being shielded.

[0040] The movable shield 15 is capable of moving, and the moving mode thereof includes, but is not limited to, one or more combinations of translation, rotation, extension and contraction, etc., and the movable shield 15 is in a shielding state or a retracted state by moving. In the shielding state, the movable shield 15 is capable of shielding the first conductive member 13 to block the first conductive member 13 from the cleaning cavity Q and the cleaning liquid in the cleaning cavity Q. In the retracted state, the movable shield 15 is staggered with the first conductive member 13, in other words, the movable shield 15 no longer shields the first conductive member 13, so that the first conductive member 13 is capable of being exposed at the cavity opening of the cover body 31 to contact the second conductive member 33 when the upper cover assembly 30 is closed.

[0041] The above cleaning machine 100, when the upper cover assembly 30 is closed, the movable shield 15 is moved to the retracted state, so that the closed upper cover assembly 30 is capable of forming electrical connection with the base assembly 10 by contacting the exposed first conductive member 13. When the upper cover assembly 30 is opened, the movable shield 15 is moved to the shielding state, so that the first conductive member 13 is capable of being shielded by the movable shield 15. Therefore, after the upper cover assembly 30 is opened, when the operation of replacing the cleaning liquid or pouring off the cleaning liquid is performed, the movable shield 15 is capable of reducing the possibility of the cleaning liquid staining the golden finger to reduce the erosion of the golden finger, and also capable of reducing the possibility of the cleaning liquid seeping into the inside of the base assembly 10 from the connecting gap around the first conductive member 13. In this way, the influence of the cleaning liquid on the base assembly 10 can be effectively reduced, which helps to improve the service life of the cleaning machine 100.

[0042] Specifically, the first conductive member 13 and the second conductive member 33 are both gold fingers. The electrical connection formed between the first conductive member 13 and the second conductive member 33 can be used to transmit electrical signals, and the base assembly 10 and the upper cover assembly 30 are thus communicatively connected.

[0043] Please refer to Figure 5 and Figure 6 , further, the seat body 11 includes an outer shell 111 and an inner shell 113 sleeved in the outer shell 111, and a mounting cavity S is formed between the outer shell 111 and the inner shell 113. The first conductive member 13 forms an electrical connection end on the surface of the inner shell 113 facing away from the mounting cavity S. The movable cover 15 is configured to switch to the shielding state by extending out of the mounting cavity S and shielding the electrical connection end, and to switch to the stowed state by retracting into the mounting cavity S and exposing the electrical connection end.

[0044] The mounting cavity S between the outer shell 111 and the inner shell 113 can be used to mount other elements included in the base assembly 10, such as a mainboard, an ultrasonic vibration head, etc. The first conductive member 13 is provided on the inner shell 113 and forms an electrical connection end on the surface of the inner shell 113 facing away from the mounting cavity S, and contacts the upper cover assembly 30 through the electrical connection end to form an electrical connection. Therefore, the electrical connection end of the first conductive member 13 is the part of the first conductive member 13 that is exposed when not shielded. Shielding or exposing the first conductive member 13 specifically refers to shielding or exposing the electrical connection end located on the surface of the inner shell 113.

[0045] The movable cover 15 is configured to move in and out of the mounting cavity S, and after extending out of the mounting cavity S, can shield the electrical connection end located on the surface of the inner shell 113, so that the originally exposed electrical connection end of the first conductive member 13 is difficult to be contacted by the cleaning liquid in the cleaning cavity Q.

[0046] Please refer to Figure 7 and Figure 8 , further, the base assembly 10 further includes a driving member 17, which is in transmission connection with the movable cover 15 to drive the movable cover 15 to switch between the shielding state and the stowed state.

[0047] The driving member 17 can be provided in the mounting cavity, and the movable cover 15 can move under the driving of the driving member 17 to complete the state switching, which helps to reduce the operation difficulty.

[0048] It can be understood that in some other embodiments, the movement of the movable cover 15 can be achieved by manual operation or transmission connection with the upper cover assembly 30, etc., which is not specifically limited here.

[0049] In some embodiments, the inner shell 113 is configured with a telescopic opening D communicating with the mounting cavity S, and the telescopic opening D extends along a first direction. The movable cover 15 is configured to rotate around the first direction under the driving of the driving member 17 to telescope in and out of the mounting cavity S from the telescopic opening D.

[0050] wherein the first direction corresponds to Figure 6 The second direction is perpendicular to the paper surface, and the stretchable opening D is in an elongated shape. It can be understood that the movable cover 15 is arc-shaped around the first direction, and under the driving of the driving member 17, the movable cover 15 can rotate and gradually extend out of the mounting cavity S or retract into the mounting cavity S, and after extending out of the mounting cavity S, it covers the power connection end of the first conductive member 13.

[0051] Further, the driving member 17 is configured with an arc-shaped sliding groove H, and the end of the movable cover 15 in the first direction is configured with a transmission shaft 151. The driving member 17 is in transmission connection with the transmission shaft 151, so as to drive the transmission shaft 151 to move along the arc-shaped sliding groove H, and drive the movable cover 15 to rotate around the first direction.

[0052] The transmission shaft 151 extends into the arc-shaped sliding groove H and moves along the arc-shaped sliding groove H under the driving of the driving member 17, so that the entire movable cover 15 moves along the arc-shaped sliding groove as a preset path, and rotates around the first direction.

[0053] It can be understood that when the transmission shaft 151 moves to the two ends of the arc-shaped sliding groove H respectively, the movable cover 15 can correspond to the shielding state and the retracted state respectively. The base assembly 10 can include two driving members 17 arranged opposite to each other in the first direction, and the movable cover 15 is configured with a transmission shaft 151 at both ends in the first direction and is in transmission connection with the two driving members 17 respectively, so as to stably drive the movable cover to rotate.

[0054] The driving member 17 is in transmission connection with the movable cover 15 through the transmission shaft 151 at both ends, without the need for a rotating shaft and a connecting structure connecting the rotating shaft and the movable cover 15. In this way, the movable cover 15 can be less disturbed by the transmission structure during the stretching and retracting process.

[0055] Please refer again to Figure 4 In some embodiments, the seat body 11 is configured with a surrounding plate 115 on the side of the first conductive member 13. The movable cover 15 is configured to enclose the first conductive member 13 with the surrounding plate 115 in the shielding state.

[0056] Specifically, the surrounding plate 115 is configured on the surface of the inner shell 113 facing away from the mounting cavity S and is distributed on the side of the power connection end. When the movable cover 15 is in the shielding state, it is in contact with the surrounding plate 115 and forms an enclosure of the first conductive member 13.

[0057] The surrounding plate 115 can make up for the insufficient shielding of the movable cover 15 on the side of the first conductive member 13, and strengthen the shielding effect of the first conductive member 13.

[0058] Further, the seat body 11 is configured with two opposite enclosing plates 115 in the first direction. The movable cover 15 is configured to be between the two enclosing plates 115 in the shielding state.

[0059] In other words, in the shielding state, the enclosing plates 115 are located at the two ends of the movable cover 15 in the first direction. The movable cover 15 can form a complete enclosure with the two enclosing plates 115 by moving between the two enclosing plates 115.

[0060] The enclosing plates 115 can generate a pre-shielding range on both sides of the first conductive part 13, and the movable cover 15 only needs to move between the two to form a complete shielding. The difficulty of the movable cover 15 shielding the first conductive part 13 is reduced.

[0061] Further, the cavity opening of the cleaning cavity Q is configured as a stepped shape, and the first conductive part 13 and all the enclosing plates 115 are arranged at the cavity opening. The cavity opening is configured with a clamping groove K between the enclosing plates 115 in the first direction, and the movable cover 15 is configured to be partially clamped into the clamping groove K in the shielding state.

[0062] The stepped cavity opening has two intersecting steps, and the power connection end of the first conductive part 13 can be formed on one of the steps, the enclosing plates 115 connect the two steps, and the clamping groove K is opened on at least one step.

[0063] The two ends of the movable cover 15 in the first direction respectively abut against the two enclosing plates 115, and the end in the direction intersecting the first direction can be clamped into the clamping groove K, thereby reducing the infiltration of the cleaning liquid.

[0064] Specifically, in the process of switching to the shielding state, one end of the movable cover 15 extends from the opening D, and this end is clamped into the clamping groove K when the movable cover 15 switches to the shielding state.

[0065] In some embodiments, the base assembly 10 further includes a sensing part 19 (as shown in Figure 6 The driving part 17 is in communication connection with the sensing part 19, and is configured to drive the movable cover 15 to move and switch to the shielding state when the sensing part 19 senses that the upper cover assembly 30 is opened, and to drive the movable cover 15 to move and switch to the retracted state when the sensing part 19 senses that the upper cover assembly 30 is closed.

[0066] The driving part 17 is in communication connection with the sensing part 19 and can perform corresponding operations based on the detection result of the sensing part 19. In this way, the driving part 17 can automatically control the state of the movable cover 15 with the help of the sensing part 19, thereby improving the accuracy of the shielding state.

[0067] In one embodiment, the inductive element 19 is configured to sense the open or closed state of the upper cover assembly 30. It is understood that when the upper cover assembly 30 is in the open state, the driving element 17 should drive the mobile cover 15 to switch to the shielding state for the mobile cover 15 that is not in the shielding state, and the driving element 17 can not act for the mobile cover 15 that is already in the shielding state. Similarly, when the upper cover is in the closed state, the driving element 17 should drive the mobile cover 15 to switch to the stowed state for the mobile cover 15 that is not in the stowed state, and the driving element 17 can not act for the mobile cover 15 that is already in the stowed state. In other embodiments, the inductive element 19 can also be configured to sense the opening or closing action of the upper cover assembly 30. It is understood that when the upper cover assembly 30 is opened, the driving element 17 correspondingly drives the mobile cover 15 to switch to the shielding state. When the upper cover assembly 30 is closed, the driving element 17 correspondingly drives the mobile cover 15 to switch to the stowed state.

[0068] Further, the inductive element 19 is configured to sense whether the upper cover assembly 30 is within a set range. When the upper cover assembly 30 is within the set range, the inductive element 19 determines that the upper cover assembly 30 is closed. When the upper cover assembly 30 is not within the set range, the inductive element 19 determines that the upper cover assembly 30 is open.

[0069] In this way, the open state and the closed state of the upper cover assembly 30 each have a certain range, which provides a certain response time for the driving element 17 and the mobile cover 15. On the one hand, the mobile cover 15 shields the first conductive element 13 after the second conductive element 33 is separated from the first conductive element 13 to a certain extent. On the other hand, the mobile cover 15 eliminates the shielding when the second conductive element 33 is within a certain range close to the first conductive element 13, so that the second conductive element 33 and the first conductive element 13 can be in contact again.

[0070] Specifically, the driving element 17 can drive the mobile cover 15 to switch to the shielding state when the sensing target is out of the set range, and drive the mobile cover 15 to switch to the stowed state when the sensing target is within the set range.

[0071] In addition, the upper cover assembly 30 can further include a sensing target, and the inductive element 19 is configured to sense whether the sensing target is within a set range, so as to improve the accuracy of sensing. The sensing target can be a component specially configured to cooperate with the inductive element 19 and arranged on the cover body 31, or can be a selected structure on the cover body 31, as long as the sensing target can follow the opening and closing of the cover body 31. Whether the sensing target is within the set range can reflect the opening and closing of the upper cover assembly 30. The opening and closing of the upper cover assembly 30 is determined based on whether the sensing target is within the set range, and the driving element 17 drives the mobile cover 15 based on the determination.

[0072] The sensing element 19 can be, but is not limited to, a Hall element, an infrared distance sensor, etc. It can be understood that in some other embodiments, the sensing element 19 can also be a light sensing element, a contact switch, or an angle sensor for measuring the opening angle of the cover assembly 30, etc., which are not specifically limited herein.

[0073] In use, the cleaning machine 100 is first opened by the cover assembly 30. When the cover assembly 30 is opened to a certain extent and the sensing element 19 cannot sense the cover assembly 30, the driving element 17 drives the movable cover 15 to extend from the telescopic opening D until one end of the movable cover 15 is clamped into the clamping groove K, and the movable cover 15 is switched to the shielding state. After the movable cover 15 is switched to the shielding state, the movable cover 15 cooperates with the surrounding plate 115 to shield the power connection end of the first conductive element 13, thereby reducing the possibility of contact with the cleaning liquid. Then, an appropriate amount of cleaning liquid is injected into the cleaning cavity Q, the cleaning object is placed, and the cover assembly 30 is closed. When the cover assembly 30 is closed to a certain extent and the sensing element 19 senses the cover assembly 30, the driving element 17 drives the movable cover 15 to retract from the telescopic opening D to the mounting cavity S, and the movable cover 15 is switched to the stowed state. When the cover assembly 30 is completely closed, the cover assembly 30 is in contact with the first conductive element 13 through the second conductive element 33 to form an electrical connection. At this time, the ultrasonic cleaning function of the cleaning machine 100 can be started to clean. After cleaning is completed, the cover assembly 30 is opened. Similarly, when the cover assembly 30 is opened to a certain extent and the sensing element 19 cannot sense the cover assembly 30, the driving element 17 drives the movable cover 15 to extend from the telescopic opening D until one end of the movable cover 15 is clamped into the clamping groove K, and the movable cover 15 is switched to the shielding state. After the movable cover 15 is switched to the shielding state, the first conductive element 13 is protected by the movable cover 15, and the operation of pouring or replacing the cleaning liquid can be performed.

[0074] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not conflict, they should be considered within the scope of the present disclosure.

[0075] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these are within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
