Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinets, and in particular to a high and low voltage power distribution cabinet with a safety protection function. Background Art

[0002] High and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. Low voltage distribution cabinets are then led to distribution boards, control boxes and switch boxes for each power user. The equipment inside is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.

[0003] Because distribution cabinets are usually installed outdoors, they have strong anti-interference capabilities, such as earthquake resistance and impact resistance. However, because they are installed outdoors, after a long period of use, a certain amount of dust will often accumulate in the ventilation and heat dissipation areas of the distribution cabinets. If they are not cleaned in time, the heat dissipation of the distribution cabinets may decrease, causing overheating inside the distribution cabinets and resulting in damage to parts.

[0004] Therefore, the existing demand is not met, and we have proposed a high and low voltage distribution cabinet with safety protection function. Summary of the invention

[0005] The present invention provides a high and low voltage power distribution cabinet with a safety protection function. A rotating base and a cleaning plate are arranged inside the air intake cavity, so that when the rotating base rotates, the cleaning plate can be driven to rotate, thereby driving a plurality of cleaning brush heads on the cleaning plate to complete the cleaning of the second heat dissipation holes on the inner wall of the air intake cavity. This solves the problem mentioned in the above background technology that a certain amount of dust is often deposited at the ventilation and heat dissipation points. If it is not cleaned in time, it is very likely to cause the heat dissipation of the power distribution cabinet to decrease, thereby causing overheating inside the power distribution cabinet and causing damage to parts.

[0011] As an optional solution for a high and low voltage distribution cabinet with safety protection function described in the present invention, a movable slide is slidably arranged inside the cleaning plate, and a fixed connection is formed between one side surface of the movable slide and one end of the second slide rod, and the other end of the second slide rod is slidably arranged inside the second track groove.

[0012] As an optional solution for a high and low voltage distribution cabinet with safety protection function described in the present invention, the movable slide is also fixedly connected to a movable push rod for driving the cleaning brush holder to move, and a third movable groove for the movable push rod to move is also opened inside the cleaning plate.

[0013] As an optional solution for a high and low voltage distribution cabinet with safety protection function described in the present invention, wherein: a plurality of rotating racks are arranged inside each of the first movable grooves, and a plurality of the rotating racks are alternately arranged on the side walls of the first movable groove, and a rotating gear is installed on the cleaning brush seat, and the rotating gear is alternately meshed with the plurality of rotating racks.

[0014] As an optional solution for a high and low voltage distribution cabinet with safety protection function described in the present invention, one end of the cleaning brush head close to the cleaning brush seat is fixedly connected to a second connecting rod, and the other end of the second connecting rod is slidably arranged inside the cleaning brush seat.

[0015] As an optional solution for a high and low voltage distribution cabinet with safety protection function described in the present invention, wherein: two first connecting rods are also connected to the second connecting rod, and the other ends of the two first connecting rods are connected to connecting balls. A fourth moving groove is opened on the side wall of the first moving groove, and the connecting ball is slidably arranged inside the fourth moving groove.

[0016] As an optional solution for a high and low voltage distribution cabinet with safety protection function described in the present invention, the fourth movable groove is opened inside the cleaning plate, a limited flap is also arranged inside the fourth movable groove, and a fifth movable groove for the first connecting rod to slide is also opened on the cleaning brush seat.

[0017] As an optional solution of a high and low voltage power distribution cabinet with safety protection function described in the present invention, first heat dissipation holes are opened on the inner walls on both sides of the cabinet body, and the first heat dissipation holes are used to connect the cabinet body and the heat dissipation box.

[0018] The present invention has the following beneficial effects:

[0019] 1. The high and low voltage distribution cabinet with safety protection function is provided with a rotating base and a cleaning plate in each air inlet cavity. The rotation of the rotating base can drive the cleaning plate to rotate, so that a plurality of cleaning brush heads arranged on the cleaning plate can effectively complete the cleaning effect of the second heat dissipation hole. In addition, a first sliding bar is arranged on the cleaning plate, and one end of the first sliding bar is slidably arranged in the first track groove. Since the first moving station and the second moving station in the first track groove are alternately opened, when the first sliding bar slides in the first track groove, it will also drive the cleaning plate to move in a reciprocating manner. The reciprocating movement of the cleaning plate also effectively increases the cleaning range of the cleaning brush head for the second heat dissipation hole, thereby further improving the cleaning efficiency of the second heat dissipation hole.

[0020] 2. The high and low voltage distribution cabinet with safety protection function is provided with a movable slide plate for sliding inside the cleaning plate. Therefore, when the cleaning plate rotates, the second slide bar arranged on the movable slide plate will also synchronously slide correspondingly inside the second track groove. Through this sliding, the movable slide plate will be driven to move back and forth, thereby driving the cleaning brush seat to perform corresponding reciprocating movement inside the first moving groove. Since the opening shape of the first moving groove is a Z-shape and a rotating rack is also provided on the inner wall, the reciprocating movement of the cleaning brush seat can not only change the cleaning range of the cleaning brush head arranged on the cleaning brush seat, but also allow the cleaning brush seat to rotate accordingly during the movement, thereby further allowing the cleaning brush head arranged on the cleaning brush seat to complete the cleaning effect of the second heat dissipation hole in a rotating manner, thereby further improving the cleaning efficiency of the second heat dissipation hole.

[0021] 3. The high and low voltage distribution cabinet with safety protection function is provided with a first connecting rod on the cleaning brush head. The first connecting rod is slidably arranged in the fourth movable groove through a connecting ball. Since the fourth movable groove is divided into a fifth movable station and a sixth movable station, when the connecting ball connected to the first connecting rod slides from the fifth movable station into the sixth movable station, the first connecting rod will collide with the cleaning base. This collision can also vibrate the cleaning brush head to a certain extent, thereby allowing the dust adhering to the cleaning brush head to fall off, so that the use time of the cleaning brush head can be extended, and more dust can be removed.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For example, see Figure 1-Figure 5 A high and low voltage power distribution cabinet with safety protection function comprises a cabinet 1, heat sinks 2 are fixedly mounted on both sides of the cabinet 1, first heat dissipation holes 101 are opened on the inner walls of both sides of the cabinet 1, and the first heat dissipation holes 101 are used to connect the cabinet 1 and the heat dissipation box 2. Figure 1 It can be seen that there are multiple groups of first heat dissipation holes 101. This arrangement allows the heat generated by parts at different heights of the cabinet 1 to enter the heat dissipation box 2 through adjacent first heat dissipation holes 101, thereby improving the heat dissipation efficiency inside the cabinet 1 to a certain extent.

[0038] Each heat sink 2 has a plurality of air inlet cavities 202 formed therein. Figure 2 It can be seen that a plurality of air inlet cavities 202 are opened corresponding to a plurality of first heat dissipation holes 101 , so when hot air enters the heat dissipation box 2 from the first heat dissipation holes 101 , the hot air will be discharged outside the heat dissipation box 2 through the corresponding air inlet cavities 202 .

[0039] A rotating base 203 and a cleaning plate 204 are also provided inside each air inlet cavity 202. A first rotating rod 205 is provided on one side surface of the rotating base 203. Since an embedded motor is fixedly provided inside the heat sink 2, the output end of the embedded motor is fixedly connected to the other end of the first rotating rod 205. Therefore, when the user starts the embedded motor, the embedded motor will drive the first rotating rod 205 to rotate, thereby driving the rotating base 203 to rotate synchronously.

[0040] A second rotating rod 208 is also arranged between the cleaning base 211 and the rotating base 203, and the other end of the second rotating rod 208 is rotatably arranged on the inner wall of the air inlet chamber 202, so that when the rotating base 203 rotates, the cleaning base 211 will be driven by the second rotating rod 208 to rotate accordingly on the inner wall of the air inlet chamber 202.

[0041] The bottom end of the cleaning plate 204 is slidably arranged inside the cleaning base 211, so that when the cleaning base 211 rotates along with the rotating base 203, the cleaning plate 204 will also rotate synchronously along with the cleaning base 211. Since a plurality of cleaning brush heads 217 are also arranged on the cleaning plate 204, when the cleaning plate 204 rotates, the plurality of cleaning brush heads 217 will also rotate synchronously, thereby completing the cleaning effect of the dust adhered to the inner surface of the second heat dissipation hole 201 and deposited inside the hole of the second heat dissipation hole 201.

[0042] The cleaning plate 204 is also provided with a first slide bar 207, one end of which is slidably mounted on the rotating base 203, and the other end of which is slidably arranged inside the first track groove 225. By means of this arrangement, while the cleaning plate 204 is rotating, the first slide bar 207 arranged on the cleaning plate 204 will synchronously slide inside the first track groove 225. The first track groove 225 is divided into a first moving station 2251 and a second moving station 2252. The first moving station 2251 and the second moving station 2252 are alternately arranged and connected, and the first moving station 2251 is closer than the second moving station 2252. The cleaning plate 204 is slidably arranged inside the cleaning base 211, so the movement of the first sliding bar 207 will also drive the cleaning plate 204 to move away from the cleaning base 211. This movement also allows the cleaning brush heads 217 arranged on the cleaning base 211 to expand the cleaning range of the second heat dissipation hole 201, thereby further improving the cleaning efficiency of the second heat dissipation hole 201.

[0043] At the same time, since the first moving station 2251 and the second moving station 2252 in the first track groove 225 are arranged in a circular array, when the first slide bar 207 slides in the first track groove 225, it will also drive the cleaning plate 204 to move back and forth, so that the plurality of cleaning brush heads 217 can reciprocate to complete the cleaning effect of the second heat dissipation hole 201, thereby further improving the cleaning efficiency of the second heat dissipation hole 201;

[0044] Moreover, a connecting spring 223 for resetting is also provided between the cleaning plate 204 and the cleaning base 211. Through this arrangement, after the cleaning plate 204 follows the first slide bar 207 to move to the inside of the second movable station 2252, the resetting elastic force of the connecting spring 223 can also quickly drive the first slide bar 207 to reset to the first movable station 2251, thereby driving the cleaning plate 204 to quickly complete the resetting, so as to better complete the above-mentioned reciprocating cleaning of the second heat dissipation hole 201.

[0045] It should be noted that since a sliding groove for the first slide bar 207 to move is also provided on the rotating base 203, when the first slide bar 207 slides from the first moving station 2251 in the first track groove 225 into the second moving station 2252, the first slide bar 207 can also effectively slide on the rotating base 203 to avoid getting stuck.

[0046] It should be noted that the user can also set a corresponding cooling fan inside each air inlet cavity 202. The cooling fan is an existing technology commonly used by people in this field and will not be elaborated on here. Through the setting of the cooling fan, after the cleaning brush head 217 completes the cleaning of the dust on the second cooling hole 201, the dust can be discharged outside the heat dissipation box 2 through the wind generated by the rotation of the cooling fan, thereby further improving the cleaning effect of the second cooling hole 201.

[0047] In this embodiment: after the cabinet 1 has been used for a period of time, the user can sequentially start the built-in motor arranged inside the heat dissipation box 2. When the built-in motor drives the first rotating rod 205 to rotate, the cleaning base 211 and the cleaning plate 204 will synchronously rotate correspondingly inside the air inlet cavity 202, so that the cleaning brush heads 217 arranged on the cleaning plate 204 can not only complete the cleaning effect of the inner surface of the second heat dissipation hole 201 in a rotating manner, but also the bristles arranged on the front end surface of the cleaning brush head 217 can effectively clean the dust deposited inside the hole of the second heat dissipation hole 201;

[0048] At the same time, since a first slide bar 207 is also provided on the cleaning plate 204, when the cleaning plate 204 rotates, the first slide bar 207 will slide inside the first track groove 225, driving the cleaning plate 204 to move away from the cleaning base 211, so that the plurality of cleaning brush heads 217 provided on the cleaning plate 204 can complete the cleaning effect of the inner surface and holes at the edge of the second heat dissipation hole 201, and since the first movable station 2251 and the second movable station 2252 in the first track groove 225 are arranged in a circular array, when the first slide bar 207 slides in the first track groove 225, the plurality of cleaning brush heads 217 can reciprocate to complete the cleaning effect of the second heat dissipation hole 201, thereby further improving the cleaning efficiency of the second heat dissipation hole 201.

[0049] Embodiment 2: This embodiment is intended to promote the solution of the problem that the cleaning plate 204 is driven to rotate by rotating the base 203, which may cause the cleaning brush head 217 on the cleaning plate 204 to have a relatively single cleaning range for the second heat dissipation hole 201, so that the cleaning degree of many places of the second heat dissipation hole 201 is insufficient. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 5-8 A movable slide 222 is also slidably arranged inside the cleaning plate 204, and one end of the second slide bar 210 is fixedly connected to the movable slide 222, and the other end of the second slide bar 210 is slidably arranged inside the second track groove 226. Through the above arrangement, the movable slide 222 can synchronously rotate with the cleaning plate 204, and because the bottom of the movable slide 222 is also slidably arranged inside the second track groove 226 through the second slide bar 210, when the movable slide 222 rotates, the second slide bar 210 will also perform a corresponding sliding effect inside the second track groove 226.

[0050] Since the second track groove 226 is divided into a third moving station 2261 and a fourth moving station 2262, the third moving station 2261 and the fourth moving station 2262 are connected, and the third moving station 2261 is closer to the center position of the inner wall of the air inlet chamber 202 than the fourth moving station 2262, and the third moving station 2261 and the fourth moving station 2262 are both arranged in a circular array, so when the second slide bar 210 slides from the third moving station 2261 in the second track groove 226 into the fourth moving station 2262, the second slide bar 210 will drive the moving slide plate 222 to move away from the cleaning base 211 inside the cleaning plate 204. The moving slide plate 222 is also fixedly connected to a moving push rod 214 for driving the cleaning brush holder 212 to move. Through this arrangement, the moving slide plate 222 can be moved while the moving push rod 214 can also drive the cleaning brush holder 212 arranged inside the cleaning plate 204 to move synchronously.

[0051] The cleaning plate 204 is also provided with a second moving groove 209 for the second slide bar 210 to slide. This arrangement allows the second slide bar 210 to avoid being stuck when moving through the arrangement of the second moving groove 209 .

[0052] A plurality of rotating racks 215 are provided inside each first movable groove 206, and the plurality of rotating racks 215 are alternately arranged on the side walls of the first movable groove 206. A rotating gear 213 is installed on the cleaning brush seat 212, and the rotating gear 213 is alternately meshed with the plurality of rotating racks 215. When the cleaning brush seat 212 is driven by the moving push rod 214 to move inside the first movable groove 206, the meshing between the rotating gear 213 and the rotating rack 215 allows the cleaning brush seat 212 to complete a corresponding rotation effect during the movement. When the cleaning brush seat 212 rotates, the cleaning brush head 217 arranged inside the cleaning brush seat 212 will also rotate synchronously, so that the cleaning brush head 217 can complete the cleaning effect of the second heat dissipation hole 201 in a rotating manner, thereby further improving the degree of cleaning dust on the second heat dissipation hole 201.

[0053] See also Figure 5 and Figure 6 It can be seen that since the first movable groove 206 is set to a Z shape, when the movable push rod 214 drives the cleaning brush holder 212 to move, the cleaning brush holder 212 will not only perform a corresponding lateral movement, so that the cleaning brush head 217 set on the cleaning brush holder 212 can further improve the lateral cleaning range of the cleaning brush head 217 on the basis of the original cleaning range, thereby effectively improving the cleaning efficiency of the cleaning brush head 217, and through the Z-shaped first movable groove 206, the cleaning brush holder 212 can also perform longitudinal movement during the lateral movement. This setting also further improves the cleaning range of the cleaning brush head 217 set inside the cleaning brush holder 212, thereby further improving the cleaning effect of the cleaning brush head 217 on the second heat dissipation hole 201.

[0054] A third movable groove 216 for the movable push rod 214 to move is also provided inside the cleaning plate 204. When the movable push rod 214 drives the cleaning brush holder 212 to move, the cleaning brush holder 212 will move longitudinally during the lateral movement. The longer movable push rod 214 can effectively drive the cleaning brush holder 212 to move accordingly. The third movable groove 216 allows the longer movable push rod 214 to slide inside the cleaning plate 204 and avoids jamming.

[0055] At the same time, since the third moving station 2261 and the fourth moving station 2262 in the second track groove 226 are also arranged in a circular array, when the second slide bar 210 slides in the second track groove 226, it will also drive the moving slide plate 222 to move back and forth inside the cleaning plate 204. The reciprocating movement of the moving slide plate 222 will also allow the several moving push rods 214 set on the moving slide plate 222 to drive the cleaning brush holder 212 to perform corresponding reciprocating movements inside the corresponding first moving groove 206, and then the cleaning brush head 217 set inside the cleaning brush holder 212 can reciprocate to complete the above-mentioned cleaning effect on the second heat dissipation hole 201, thereby further improving the cleaning efficiency of the second heat dissipation hole 201.

[0056] In this embodiment: since the cleaning plate 204 is provided with a movable slide plate 222 for sliding movement inside, and the movable slide plate 222 is slidably provided inside the second track groove 226 through the second slide bar 210, when the cleaning plate 204 rotates, the second slide bar 210 provided on the movable slide plate 222 will also synchronously rotate correspondingly inside the second track groove 226, and the second slide bar 210 drives the movable slide plate 222 to slide inside the cleaning plate 204, thereby allowing the plurality of movable push rods 214 provided on the movable slide plate 222 to drive the corresponding cleaning brush holder 212 to synchronously move inside the corresponding first movable groove 206;

[0057] Furthermore, since a rotating gear 213 is installed on each cleaning brush holder 212, and rotating racks 215 are alternately arranged on the inner wall of the first movable groove 206, when the cleaning brush holder 212 moves inside the first movable groove 206, the rotating gear 213 will alternately mesh with the rotating rack 215, thereby allowing the cleaning brush holder 212 to complete the corresponding rotation during the movement. Through the setting of the cleaning brush head 217, when the cleaning brush holder 212 rotates, the cleaning brush head 217 will also rotate synchronously, thereby allowing the cleaning brush head 217 to complete the cleaning effect of the second heat dissipation hole 201 in a rotating state when cleaning the second heat dissipation hole 201, thereby further improving the cleaning efficiency of the cleaning brush head 217 on the dust on the second heat dissipation hole 201.

[0058] Furthermore, since the opening shape of the first movable groove 206 is a Z-shape, when the cleaning brush holder 212 moves inside the first movable groove 206, the cleaning brush holder 212 will not only perform a corresponding lateral movement, so that the cleaning brush head 217 set on the cleaning brush holder 212 can further increase the lateral cleaning range of the cleaning brush head 217 on the basis of the original cleaning range, thereby effectively improving the cleaning efficiency of the cleaning brush head 217, and the Z-shaped first movable groove 206 can also allow the cleaning brush holder 212 to move longitudinally during the lateral movement. This arrangement also further improves the cleaning efficiency of the cleaning brush head 217. The cleaning range of the cleaning brush head 217 inside the cleaning brush holder 212 further improves the cleaning effect of the cleaning brush head 217 on the second heat dissipation hole 201, and because the third moving station 2261 and the fourth moving station 2262 in the second track groove 226 are arranged in a circular array, when the second slide bar 210 slides in the second track groove 226, it will also drive the moving slide plate 222 to move back and forth, so that the cleaning brush head 217 set in the cleaning brush holder 212 can reciprocate to complete the above-mentioned cleaning effect on the second heat dissipation hole 201, thereby further improving the cleaning efficiency of the second heat dissipation hole 201.

[0059] Embodiment 3: This embodiment is intended to promote the solution of the problem that after the cleaning brush head 217 cleans the second heat dissipation hole 201 for a period of time, a certain amount of dust may adhere to the cleaning brush head 217, thereby causing the cleaning brush head 217 to have a poor cleaning effect on the second heat dissipation hole 201. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 9-11 The cleaning brush head 217 is fixedly connected to one end of the cleaning brush seat 212 with a second connecting rod 221, and the other end of the second connecting rod 221 is slidably arranged inside the cleaning brush seat 212. The second connecting rod 221 is also connected to two first connecting rods 218, and the other ends of the two first connecting rods 218 are connected to connecting balls 219, which are slidably arranged inside the fourth moving groove 224. Through this arrangement, when the mobile push rod 214 drives the cleaning brush seat 212 to move, the fourth moving groove 224 is opened, which can not only effectively The stability of the movement of the cleaning brush holder 212 is ensured, and the stability of the cleaning brush head 217 when brushing is ensured. In addition, the fourth movable groove 224 allows the cleaning brush holder 212 to move at the same horizontal height during movement. Therefore, even if the cleaning brush holder 212 rotates under the meshing action of the rotating gear 213 and the rotating rack 215, the first connecting rod 218 arranged on the second connecting rod 221 will only rotate at the same horizontal height as the fourth movable groove 224, and will not get stuck.

[0060] See also Fig.11It can be seen that since the fourth movable groove 224 is divided into the fifth movable station 2241 and the sixth movable station 2242, the fifth movable station 2241 and the sixth movable station 2242 are connected, and the sixth movable station 2242 is opened closer to the second heat dissipation hole 201, and before the cleaning brush holder 212 moves to the end of the first movable groove 206, the first connecting rod 218 will only slide inside the fifth movable station 2241. When the cleaning brush holder 212 moves to the end of the first movable groove 206, the connecting ball 219 connected to the first connecting rod 218 will move to the sixth movable station 2242. This arrangement not only allows the second connecting rod 221, which is fixedly connected to the first connecting rod 218, to move accordingly, but also allows The cleaning brush head 217 fixedly connected with the second connecting rod 221 fits more closely to the surface of the second heat dissipation hole 201, so that the bristles at the front end of the cleaning brush head 217 can contact the second heat dissipation hole 201 more fully, thereby effectively improving the cleaning effect of the cleaning brush head 217 on the second heat dissipation hole 201, and when the connected connecting ball 219 moves from the fifth moving station 2241 to the sixth moving station 2242, the first connecting rod 218 will also collide with the cleaning base 211, and this collision can also vibrate the cleaning brush head 217 to a certain extent, so that the dust adhering to the cleaning brush head 217 can fall off, so that the use time of the cleaning brush head 217 can be extended, and more dust can be removed.

[0061] The cleaning brush holder 212 is also provided with a fifth moving groove 220 for the first connecting rod 218 to slide. This arrangement is to prevent the first connecting rod 218 from getting stuck when moving.

[0062] A limit flap 228 is also disposed inside the fourth moving groove 224. Fig.11It can be seen that when the connecting ball 219 slides to the inside of the sixth moving station 2242 in the fourth moving groove 224, if the cleaning brush seat 212 is reset under the drive of the moving push rod 214, due to the position difference between the fifth moving station 2241 and the sixth moving station 2242, the connecting ball 219 will only reset along the sixth moving station 2242. At the same time, since a reset slope and a limit flap 228 are also provided at the end of the sixth moving station 2242, and the flipping direction of the limit flap 228 can only be in the counterclockwise direction. Flip, so under the action of the reset slope and the limit flap 228, the connecting ball 219 will be reset to the inside of the fifth moving station 2241 again, so that the first connecting rod 218 fixedly connected with the connecting ball 219 can once again complete the collision with the cleaning base 211, thereby vibrating the cleaning brush head 217 again, so as to further improve the cleaning of the cleaning brush head 217, and through this reset, the subsequent first connecting rod 218 and the connecting ball 219 can still perform the above-mentioned movement effect when they move again.

[0063] It should be noted that a torsion spring is also provided between the limit flap 228 and the fourth movable groove 224 for resetting the limit flap 228. Therefore, when the connecting ball 219 contacts the limit flap 228 driven by the resetting slope, even if the limit flap 228 is flipped, it will be reset under the action of the resetting elastic force of the torsion spring, so that when the connecting ball 219 and the first connecting rod 218 are subsequently moved to the position of the limit flap 228 again, they can pass through the limit flap 228 smoothly.

[0064] It should be noted that when the cleaning brush holder 212 moves to the end of the first movable groove 206 driven by the moving push rod 214, the inner wall of the first movable groove 206 at this time does not have a rotating rack 215, so the cleaning brush holder 212 will only move simply and will not rotate. This setting is to avoid the first connecting rod 218 and the connecting ball 219 being separated from the fourth movable groove 224 if the cleaning brush holder 212 continues to rotate, thereby affecting the collision cleaning effect of the cleaning brush head 217.

[0065] In this embodiment: a fourth movable groove 224 is opened inside the cleaning plate 204, and the second connecting rod 221 sliding inside the cleaning base 211 is slidably set inside the fourth movable groove 224 through the first connecting rod 218, and since the fourth movable groove 224 is divided into a fifth movable station 2241 and a sixth movable station 2242, when the connecting ball 219 connected to the first connecting rod 218 slides from the fifth movable station 2241 into the sixth movable station 2242, the first connecting rod 218 will collide with the cleaning base 211. This collision can also vibrate the cleaning brush head 217 to a certain extent, thereby allowing the dust adhering to the cleaning brush head 217 to fall off, so that the use time of the cleaning brush head 217 can be extended, and more dust can be removed.
