Technical Field

[0001] This disclosure pertains to the field of power equipment technology, and specifically relates to an electrical cabinet. Background Technology

[0002] Electrical cabinets are typically made of steel and are used to house electronic components. They are widely used in various industries. Because electrical cabinets contain multiple electrical components, which inevitably generate a lot of heat during operation, cooling devices are required inside the cabinets.

[0003] In related technologies, the heat dissipation device is generally a fan. The fan is located inside the electrical cabinet and connected to the inner wall of the cabinet. Heat dissipation is achieved by blowing air into the electrical cabinet through the fan.

[0004] However, in the above structure, the fan can only blow air in one direction, resulting in uneven heat dissipation and poor heat dissipation effect when the internal temperature of the electrical cabinet is high. Summary of the Invention

[0005] This disclosure provides an electrical cabinet that can dissipate heat from multiple locations inside the cabinet when the internal temperature is high, thereby improving the heat dissipation effect. The technical solution is as follows:

[0006] This disclosure provides an electrical cabinet, which includes a housing, a mounting bracket, a fan, and a blower assembly. The mounting bracket is located inside the housing and connected to the inner wall of the housing, dividing the interior of the housing into a first cavity and a second cavity. The fan is located in the first cavity and connected to the housing. The blower assembly includes a bracket and multiple blowers.

The cleaning assembly includes multiple second telescopic rods, a cleaning bracket, and multiple cleaning cylinders. The multiple second telescopic rods are spaced apart along the arrangement direction of the multiple air blowers, and the fixed end of the second telescopic rod is connected to the inner wall of the cabinet, while the telescopic end of the second telescopic rod is connected to the cleaning bracket. The second telescopic rods are capable of telescopic extension and retraction along the arrangement direction. The multiple cleaning cylinders are arranged in a one-to-one correspondence with the multiple air blowers, and the cleaning cylinders are coaxially and slidably sleeved on the outside of the corresponding air blower to clean the air holes of the corresponding air blower.

[0012] In another implementation of this disclosure, the cleaning assembly further includes multiple cleaning components and a cleaning drive component. The multiple cleaning components are arranged in a one-to-one correspondence with the multiple blowers and the multiple cleaning cylinders. Each cleaning component includes a top rod, a turntable, and multiple telescopic cleaning components. The first end of the top rod is rotatably connected to the cleaning bracket, and the second end of the top rod faces the blower corresponding to the cleaning component. The turntable is movably located within the blower corresponding to the cleaning component along the arrangement direction and is rotatably connected to the blower. The turntable is detachably engaged with the second end of the top rod to rotate with the top rod. The multiple telescopic cleaning components are spaced apart and embedded in the turntable. The telescopic cleaning components can extend and retract radially along the turntable to reach into the blower holes of the blower to clean the blower holes.

The fourth elastic element extends and retracts along the axial direction of the corresponding blower.

[0016] The beneficial effects of the technical solutions provided in this disclosure are:

[0017] Because the mounting bracket divides the interior of the cabinet into a first cavity and a second cavity, and the fan is located in the first cavity, the fan can blow air to dissipate heat from inside the electrical cabinet.

[0018] Because the air blower is located within the second cavity, and the bracket can switch between the first and second states, the bracket can be controlled to be in different states accordingly. When the bracket is in the first state, the cool air blown by the fan can enter the air blower through the ventilation holes, and then blow air onto the electrical components at different locations in the second cavity through the other end of each air blower, greatly improving the air blowing efficiency. When the bracket is in the second state, the cool air blown by the fan blows through the gaps onto the mounting bracket, thereby providing overall heat dissipation for the electrical components on the mounting bracket.

[0029] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0030] This disclosure provides an electrical cabinet, such as... Figure 1 As shown, the electrical cabinet includes a housing 1, a fan 3, a mounting bracket 2, and a blower assembly 4.

[0031] Mounting bracket 2 is located inside housing 1 and connected to the inner wall of housing 1. Mounting bracket 2 divides the interior of housing 1 into a first cavity 101 and a second cavity 102. Fan 3 is located inside the first cavity 101 and connected to the inner wall of housing 1.

[0032] The blower assembly 4 includes a bracket 41 and multiple blower nozzles 42. The bracket 41 is located inside the first cavity 101 and is slidably connected to the inner wall of the housing 1. The bracket 41 has multiple ventilation holes 410, which are spaced apart along a direction perpendicular to the arrangement direction of the first cavity 101 and the second cavity 102. The multiple blower nozzles 42 are connected to the mounting bracket 2, and each blower nozzle 42 is arranged in a one-to-one correspondence with a ventilation hole 410. One end of each blower nozzle 42 is coaxially arranged with the corresponding ventilation hole 410, and the other end of each blower nozzle 42 is located inside the second cavity 102.

[0033] The bracket 41 is configured to switch between a first state and a second state. When the bracket 41 is in the first state, one end of the blower 42 is connected to one end of the corresponding vent 410, and the bracket 41 divides the first cavity 101 into two enclosed sub-spaces arranged along the arrangement direction. The other end of the vent 410 and the fan 3 are both located in one of the two enclosed sub-spaces away from the blower 42. When the bracket 41 is in the second state, the blower 42 and the corresponding vent 410 are separated in the blowing direction of the fan 3, and a gap 103 is formed in the bracket 41 for gas to flow between the first cavity 101 and the second cavity 102.

[0034] When the electrical cabinet provided in this embodiment is in use, the cabinet body 1 can provide a mounting base for other components of the electrical cabinet. Simultaneously, electrical components can also be mounted using the mounting bracket 2.

[0035] Since the mounting bracket 2 divides the interior of the cabinet 1 into a first cavity 101 and a second cavity 102, and the fan 3 is located in the first cavity, the fan 3 can blow air to dissipate heat from inside the electrical cabinet.

[0036] Since the blower 42 is located inside the second cavity 102, and the bracket 41 can switch between the first and second states, the bracket 41 can be controlled to be in different states. When the bracket 41 is in the first state, the cool air blown by the fan 3 can enter the blower 42 through the ventilation hole 410, and then blow air onto the electrical components at different positions in the second cavity 102 through the other end of each blower 42, greatly improving the blowing efficiency. When the bracket 41 is in the second state, the cool air blown by the fan 3 blows onto the mounting bracket 2 through the gap, so as to dissipate heat from the electrical components on the mounting bracket 2.

[0037] As can be seen, the electrical cabinet provided in this embodiment can control the bracket 41 to be in different states to reasonably dissipate heat from the electrical components on the mounting bracket 2.

[0038] In this embodiment, the air blowing direction of the fan 3 is from the first cavity 101 to the second cavity 102.

[0039] Optionally, the outer wall of the blower 42 has a plurality of air holes 420 located within the second cavity 102. In the direction of the arrangement, at least a portion of the air holes 420 blows air toward the electrical components.

[0040] The support 41 includes a movable frame 411, a sealing plate 412, and multiple insertion tubes 414. The movable frame 411 has an opening 4110 in the middle, and the outer wall of the movable frame 411 is slidably connected to and sealed with the inner wall of the housing 1. The sealing plate 412 is movably connected to the movable frame 411 and can move relative to the movable frame 411 along the arrangement direction. The multiple insertion tubes 414 are inserted into the sealing plate 412 at intervals along a direction perpendicular to the arrangement direction, and the multiple insertion tubes 414 correspond one-to-one with the multiple blowers 42. Ventilation holes 410 are formed inside the insertion tubes 414.

[0041] When the bracket 41 is in the first state, the sealing plate 412 blocks the opening 4110, and one end of the insertion tube 414 is used to insert into the blower 42. When the bracket 41 is in the second state, the sealing plate 412 is located on the side of the opening 4110 closer to the mounting bracket 2, and the sealing plate 412 and the moving frame 411 are spaced apart along the arrangement direction to form a gap 103.

[0042] In the above implementation, the support 41 is configured as described above. This allows the first cavity 101 to be divided into two closed subspaces by creating a gap between the movable frame 411 and the sealing plate 412, or by having both of them together. This allows the support 41 to be in either the second state or the first state. The insertion tube 414 is used to form a ventilation hole 410 on the support 41, so that the ventilation hole 410 communicates with the first cavity 101 and is movably connected to the blower 42.

[0043] In addition, multiple air holes 420 are provided on the outer wall of the air blower 42, and the air holes 420 are located inside the second cavity 102. This allows the air blower 42 to have multiple air outlets through the multiple air holes 420, which can blow air onto multiple positions of the mounting bracket 2 at the same time.

[0044] In this embodiment, to improve sealing, a sealing rubber layer is provided on the outer wall of the insertion tube 414. Thus, when the insertion tube 414 is inserted into the corresponding blower 42, the sealing rubber layer improves the airtightness between the insertion tube 414 and the blower 42, reducing airflow leakage between them. The sealing rubber layer can be adhered to the outer wall of the insertion tube 414.

[0045] Optionally, the movable frame 411 includes a frame body 4111, a connecting rod 4112, and a first elastic member 4113. The first end of the connecting rod 4112 is slidably connected to the frame body 4111, and the second end of the connecting rod 4112 is connected to the sealing plate 412.

[0046] The first elastic element 4113 is sleeved on the outside of the connecting rod 4112, and the first end of the first elastic element 4113 abuts against the sealing plate 412, and the second end of the first elastic element 4113 abuts against the frame 4111. The outer wall of the frame 4111 is slidably connected to and sealed with the inner wall of the box 1.

[0047] In the above implementation, since the connecting rod 4112 is slidably connected to the frame 4111, and the first elastic member 4113 is sleeved on the connecting rod 4112, and the two ends of the first elastic member 4113 abut against the frame 4111 and the sealing plate 412 respectively, when the insertion tube 414 on the sealing plate 412 is inserted into the blower 42, and the sealing plate 412 abuts against the mounting bracket 2 and cannot move, if the frame 4111 continues to move toward the mounting bracket 2, the first elastic member 4113 will be compressed under the pressure of the frame 4111, and the frame 4111 will be sleeved on the sealing plate 412, and the sealing plate 412 will seal the opening 4110. When the frame 4111 is no longer subjected to force, the frame 4111 will move away from the mounting frame 2 under the elastic force of the first elastic element 4113, so that the sealing plate 412 is located on the side of the opening 4110 close to the mounting frame 2, and the sealing plate 412 and the moving frame 411 are spaced apart along the arrangement direction to form a gap 103.

[0048] In other words, the above structure can easily realize that the support 41 is in the first state and the second state, and can also flexibly switch between the first state and the second state.

[0049] Optionally, the bracket 41 further includes a first telescopic rod 415, the fixed end of the first telescopic rod 415 is connected to the inner wall of the box 1, the telescopic end of the first telescopic rod 415 is connected to the frame 4111, and the telescopic direction of the first telescopic rod 415 is the arrangement direction.

[0050] In the above implementation, the first telescopic rod 415 is used to provide power for the movement of the frame 4111. When the first telescopic rod 415 extends, the frame 4111 can move toward the mounting frame 2, and when the first telescopic rod 415 retracts, the frame 4111 can move away from the mounting frame 2.

[0051] In this embodiment, the first telescopic rod 415 is an electric telescopic rod, which can be automatically controlled to extend and retract along its own axis by a control circuit.

[0052] In actual use, when the first telescopic rod 415 extends, it pushes the frame 4111 towards the mounting bracket 2. Simultaneously, the frame 4111, along with the sealing plate 412, moves towards the mounting bracket 2. The insertion tube 414 on the sealing plate 412 moves towards the corresponding blower 42 until it is inserted into the blower 42, and the sealing plate 412 abuts against the mounting bracket 2, preventing further movement. At this point, the first telescopic rod 415 continues to extend, pushing the frame 4111 towards the mounting bracket 2 until the sealing plate 412 is located within the opening 4110. Both the frame 4111 and the sealing plate 412 are abutting against the mounting bracket 2 and cannot move. The sealing plate 412 completely seals the opening 4110, and the cold air blown out by the fan 3 can only be blown out along the blower 42.

[0053] When the first telescopic rod 415 is retracted, the first telescopic rod 415 moves the frame 4111 back to its original position, the first elastic element 4113 resets, and the connecting rod 4112 moves the sealing plate 412 back to its original position.

[0054] For example, the frame 4111 is a plate-shaped structure with an opening in the middle. To facilitate the connection between the frame 4111 and the connecting rod 4112, an L-shaped connecting rod 4116 is connected to one side of the frame 4111 away from the mounting bracket 2. One end of the L-shaped connecting rod 4116 is fixedly connected to the frame 4111, and the other end of the L-shaped connecting rod 4116 is slidably connected to the connecting rod 4112.

[0055] To prevent the connecting rod 4112 from sliding out of the L-shaped connecting rod 4116, the first end of the connecting rod 4112 has a limiting platform, and the limiting platform and the first elastic member 4113 are located on opposite sides of the L-shaped connecting rod 4116.

[0056] Of course, the support 41 is not limited to the structure described above. For example, the support 41 can be the frame, telescopic plate, or insertion tube mentioned above. The frame has a circular hole inside, and the telescopic plate can be telescopically positioned within the circular hole via a telescopic rod. In this way, by controlling the telescopic state of the telescopic plate, the support 41 can also be in different states.

[0057] Optionally, the blower assembly 4 also includes a locking plate 43, which is located inside the first cavity 101 and is connected to the mounting bracket 2. The locking plate 43 and the mounting bracket 2 are arranged at intervals.

[0058] The outer wall of the hair dryer 42 has a limiting ring 421, which is located in the gap between the locking plate 43 and the mounting bracket 2, and abuts against the locking plate 43 and the mounting bracket 2 respectively.

[0059] In the above implementation, the cooperation between the locking plate 43 and the limiting ring 421 can further limit and fix each blower 42 on the mounting bracket 2, preventing the blower 42 from detaching from the mounting bracket 2. At the same time, the locking plate 43 is also used to quickly abut against the sealing plate 412 after the insertion tube 414 is inserted into the corresponding blower 42, so that the sealing plate 412 will no longer move.

[0060] In this embodiment, the locking plate 43 and the mounting bracket 2 are connected by fasteners such as bolts.

[0061] For example, the mounting bracket 2 includes a mounting vertical plate 21 and a connecting guide rod 22. The mounting vertical plate 21 is connected to the top, bottom, and two opposite side walls of the housing 1. The first cavity 101 and the second cavity 102 are located on opposite sides of the mounting vertical plate 21, respectively.

[0062] The connecting guide rod 22 is located at the bottom of the housing 1 and inside the first cavity 101. The first end of the connecting guide rod 22 is perpendicularly connected to the mounting vertical plate 21, and the second end of the connecting guide rod 22 is connected to the side wall of the housing 1. The axial direction of the connecting guide rod 22 is the arrangement direction. The frame 4111 is slidably connected to the connecting guide rod 22 to guide the frame 4111.

[0063] The side of the mounting plate 21 furthest from the connecting guide rod 22 is used to mount electrical components. The electrical components are arranged at intervals along an axis perpendicular to the connecting guide rod 22.

[0064] Optionally, the electrical cabinet also includes a cleaning assembly 5, which is located within the second cavity 102. The cleaning assembly 5 includes multiple second telescopic rods 51, a cleaning bracket 52, and multiple cleaning cylinders 53. The multiple second telescopic rods 51 are spaced apart along the arrangement direction of the multiple air blowers 42, and the fixed ends of the second telescopic rods 51 are connected to the inner wall of the housing 1, while the telescopic ends of the second telescopic rods 51 are connected to the cleaning bracket 52. The second telescopic rods 51 are capable of telescopic extension and retraction along the arrangement direction. The multiple cleaning cylinders 53 are arranged one-to-one with the multiple air blowers 42, and the cleaning cylinders 53 are coaxially and slidably sleeved on the outside of the corresponding air blower 42 to clean the air holes 420 of the corresponding air blower 42.

[0065] In the above implementation, when the second telescopic rod 51 extends toward the blower 42, the cleaning bracket 52 moves toward the blower 42 with the cleaning cylinder 53 until the cleaning cylinder 53 is sleeved on the outside of the corresponding blower 42. Then, the cleaning drive 54 drives the cleaning cylinder 53 to rotate. At this time, the cleaning cylinder 53 can clean the circumference of the outer wall of the blower 42 to prevent the blower holes 420 of the blower 42 from becoming blocked.

[0066] In this embodiment, the second telescopic rod 51 is an electric telescopic rod, and the extension and retraction of the second telescopic rod 51 along its own axis can be automatically controlled by the control circuit.

[0067] Figure 2 yes Figure 1 Enlarged view of point A in the middle, combined with Figure 2 Optionally, the sweeping cylinder 53 includes a rotating cylinder 531, a cleaning cylinder 532, and a brush 533. One end of the rotating cylinder 531 is connected to one end of the cleaning cylinder 532, and the other end of the rotating cylinder 531 is rotatably connected to the sweeping bracket 52. The other end of the cleaning cylinder 532 faces the blower 42. The brush 533 is located inside the cleaning cylinder 532 and is connected to the inner wall of the cleaning cylinder 532. The sweeping assembly 5 also includes a sweeping drive 54, which is connected to the inner wall of the housing 1 and is drively connected to multiple rotating cylinders 531 to drive the multiple rotating cylinders 531 to rotate around their own axes.

[0068] In the above implementation, the cleaning cylinder 53 is configured with the above structure, and can be connected to the cleaning drive component 54 via the rotating cylinder body 531, so that the cleaning cylinder 53 can rotate. The cleaning cylinder body 532 is used to provide a mounting base for the brush 533, which is used to clean the outer wall of the blower 42.

[0069] In this embodiment, the rotating cylinder 531 and the cleaning cylinder 532 are welded together, which can improve the connection strength between the two.

[0070] Of course, the structure of the sweeping cylinder 53 mentioned above can also be in other forms. For example, the rotating cylinder 531 can be omitted, and the cleaning cylinder 532 can be directly connected to the sweeping drive component 54.

[0071] See you again Figure 1 In this embodiment, the cleaning bracket 52 has an L-shaped structure and includes a horizontal plate 521 and a vertical plate 522 connected to each other. The first motor 541 is connected to the horizontal plate 521. The surface of the vertical plate 522 is perpendicular to the blowing direction of the fan 3.

[0072] Figure 3 yes Figure 1 Enlarged view at point B, combined with Figure 3 To ensure stable rotation of the multiple rotating cylinders 531, each rotating cylinder 531 has a dovetail ring 5311 on its outer peripheral wall. Correspondingly, the vertical plate 522 of the cleaning bracket 52 has multiple dovetail grooves. Each dovetail ring 5311 is rotatably located within a dovetail groove.

[0073] Combination Figure 1Optionally, the cleaning drive component 54 includes a first motor 541, a first transmission belt 542, and a plurality of first transmission wheels 543. The first motor 541 is connected to the cleaning bracket 52, and the plurality of first transmission wheels 543 are arranged in a one-to-one correspondence with a plurality of cleaning cylinders 53. The first transmission wheel 543 is sleeved on the outer wall of the corresponding cleaning cylinder 53, and the first transmission belt 542 is sleeved on the pulley on the output shaft of the first motor 541 and the plurality of first transmission wheels 543 to drive the first transmission wheels 543 to rotate.

[0074] In the above implementation, after the first motor 541 is started, the output shaft on the first motor 541 can rotate. In this way, the first transmission belt 542 is driven by the pulley on the output shaft of the first motor 541. The first transmission belt 542 will drive multiple first transmission wheels 543 to rotate. While the multiple first transmission wheels 543 are rotating, they will also drive the sweeping cylinder 53 to rotate.

[0075] Of course, the cleaning drive component 54 mentioned above can also be of other structures. For example, the first transmission belt 542 can be replaced with a transmission chain, and the corresponding pulley and transmission wheel can be set as gear structures.

[0076] Optionally, the cleaning assembly 5 also includes a plurality of cleaning components 55 and a cleaning drive component 57, wherein the plurality of cleaning components 55 are arranged in a one-to-one correspondence with a plurality of blower tubes 42 and a one-to-one correspondence with a plurality of cleaning tubes 53.

[0077] Figure 4 for Figure 1 Internal structure diagram of the blower tube, combined with Figure 4 The cleaning component 55 includes a top rod 551, a turntable 552, and multiple telescopic cleaning members 553. The first end of the top rod 551 is rotatably connected to the cleaning bracket 52, and the second end of the top rod 551 faces the corresponding blower 42 of the cleaning component 55. The turntable 552 is movably located within the corresponding blower 42 of the cleaning component 55 along its arrangement direction and is rotatably connected to the blower 42. The turntable 552 is detachably snapped into the second end of the top rod 551 to rotate with the top rod 551. Multiple telescopic cleaning members 553 are spaced apart and embedded in the turntable 552. The telescopic cleaning members 553 can extend and retract radially along the turntable 552 to reach into the blower holes 420 of the blower 420 to clean the blower holes 420. A cleaning drive 57 is connected to the cleaning bracket 52 and to the multiple top rods 551 to drive the top rods 551 to rotate around their own axes.

[0078] In the above implementation, the cleaning component 55 is used to clean the air holes 420 inside the blower 42 to prevent the air holes 420 from becoming clogged. The cleaning drive component 57 is used to drive the push rod 551 to rotate, so that the push rod 551 can rotate the turntable 552 after it rotates.

[0079] In actual operation, the push rod 551 moves towards the blower 42 along with the cleaning bracket 52 under the drive of the second telescopic rod 51. The push rod 551 can then extend into the turntable 552 and engage with it. Then, the push rod 551 can rotate along its own axis, thus rotating the turntable 552 together. As the turntable 552 rotates, it also rotates the telescopic cleaning component 553 embedded in it. The telescopic cleaning component 553 cleans the blower hole 420 while rotating, preventing it from becoming clogged.

[0080] In this embodiment, the turntable 552 has a square snap-fit ​​groove 5520 on the side facing the push rod 551. A square snap-fit ​​block 5511 is connected to the end face of the second end of the push rod 551, and the square snap-fit ​​block 5511 is movably located in the snap-fit ​​groove 5520.

[0081] In the above implementation, the structure allows the top rod 551, carrying the square snap block 5511, to rotate together with the turntable 552 after being inserted into the snap slot 5520 of the turntable 552.

[0082] Of course, the cleaning component 55 can also have other structural forms. For example, the cleaning component 55 can be a rotatable rod-shaped structure, and the outer wall of the rod-shaped structure has multiple elastic protrusions. Correspondingly, the end face of the blower tube 42 facing the rod-shaped structure has a telescopic sealing plate that can move along the arrangement direction. In this way, when the rod-shaped structure is inserted into the blower tube 42, it can push the telescopic sealing plate to move away and extend into the blower tube 42 to clean the blower holes 420 in the blower tube 42.

[0083] Optionally, the telescopic cleaning component 553 includes, in the radially outward direction of the turntable 552, a third elastic element 5531, a slider 5532, and an arc-shaped protrusion 5533. The first end of the third elastic element 5531 is connected to the turntable 552, the second end of the third elastic element 5531 is connected to one side of the slider 5532, and the other side of the slider 5532 is connected to the arc-shaped protrusion 5533. The arc-shaped protrusion 5533 is used to partially extend into the air hole 420 and slide out of the air hole 420 while the turntable 552 rotates.

[0084] In the above implementation, the telescopic cleaning member 553 is configured with the above structure, which allows the arc-shaped protrusion 5533 to extend and retract radially along the turntable 552. When the arc-shaped protrusion 5533 encounters the air hole 420, it can partially slide into the air hole 420 to clean it. When it does not encounter the air hole 420, it can retract radially inward along the turntable 552 under the pressure of the inner wall of the air blower 42. This allows the telescopic cleaning member 553 to move along with the turntable 552 within the air blower 42 and clean the air hole 420.

[0085] Of course, the telescopic cleaning component 553 can also be of other structures, such as a spring pin structure with a ball at the top.

[0086] In this embodiment, the slider 5532 has a T-shaped structure. This increases the contact area between the slider 5532 and the third elastic element 5531 through the large end of the T-shaped structure, thereby improving their stability. At the same time, the large end of the T-shaped structure can slide in contact with the interior of the turntable 552, so that the slider 5532 will not wobble when it moves radially along the interior of the turntable 552.

[0087] Combination Figure 1 For example, the cleaning drive component 57 includes a second motor 571, a second transmission belt 572, and a plurality of second transmission wheels 573. The second motor 571 is connected to the cleaning bracket 52. The plurality of second transmission wheels 573 are arranged in a one-to-one correspondence with a plurality of top rods 551. The second transmission wheels 573 are sleeved on the outer wall of the corresponding top rod 551. The second transmission belt 572 is sleeved on the pulley on the output shaft of the second motor 571 and the plurality of second transmission wheels 573 to drive the second transmission wheels 573 to rotate.

[0088] In the above implementation, after the second motor 571 is started, the output shaft on the second motor 571 can rotate, so the second transmission belt 572 is driven by the pulley on the output shaft of the second motor 571. The second transmission belt 572 will then drive multiple second transmission pulleys 573 to rotate, and the multiple second transmission pulleys 573 will drive the push rod 551 to rotate at the same time.

[0089] Of course, the cleaning drive component 57 mentioned above can also be other structural forms of the sweeping drive component 54 mentioned above, which will not be elaborated here.

[0090] In this embodiment, to facilitate the transmission connection between the push rod 551 and the cleaning drive component 57, a rotating shaft is connected to the first end of the push rod 551, and the rotating shaft is rotatably inserted into the cleaning bracket 52. The second transmission wheel 573 is sleeved on the outside of the rotating shaft.

[0091] The first transmission belt 542 and the second transmission belt 572 mentioned above are both transmission belts, and the second transmission wheel 573 and the first transmission wheel 543 are both pulleys.

[0092] In addition, to facilitate the installation of the second motor 571, the cleaning bracket 52 also includes an L-shaped frame 523. The L-shaped frame 523 is located between the vertical plate 522 and the inner wall of the housing 1, and the L-shaped frame 523 is connected to both the vertical plate 522 and the inner wall of the housing 1. The second motor 571 is connected to the L-shaped frame 523.

[0093] Combination Figure 4Optionally, the cleaning assembly 5 also includes a plurality of reset components 58, which correspond one-to-one with a plurality of blower tubes 42 and one-to-one with a plurality of turntables 552, and the reset components 58 are located inside the corresponding blower tubes 42.

[0094] The reset component 58 includes a connecting block 581, a fourth elastic element 582, and a retaining ring 583. One side of the connecting block 581 is rotatably connected to the turntable 552, and the other side of the connecting block 581 is connected to the first end of the fourth elastic element 582. The second end of the fourth elastic element 582 is connected to the retaining ring 583. The retaining ring 583 is located inside the blower tube 42 corresponding to the reset component 58, and is closer to the end of the blower tube 42 away from the push rod 551. The retaining ring 583 is connected to the inner wall of the blower tube 42 corresponding to the reset component 58. The fourth elastic element 582 extends and retracts along the axial direction of the blower tube 42.

[0095] In the above implementation, the reset component 58 is used to automatically reset the turntable 552 after it moves inside the blower tube 42.

[0096] When the turntable 552 moves inside the blower tube 42 under the drive of the push rod 551, the turntable 552 can squeeze the fourth elastic element 582, so that the fourth elastic element 582 is compressed inside the blower tube 42. When the push rod 551 moves away from the blower tube 42, the turntable 552 can automatically reset under the action of the fourth elastic element 582.

[0097] In this embodiment, to ensure that the connecting block 581 can move smoothly along the inside of the blower 42 without rotating, the reset component 58 further includes two guide blocks 584. These two guide blocks 584 are symmetrically arranged along the axis of the blower 42, and both guide blocks 584 are connected to the connecting block 581. The inner wall of the blower 42 has two opposing guide grooves 4100, which extend along the axial direction of the blower 42. The two guide blocks 584 are arranged in a one-to-one correspondence with the two guide grooves 4100, and each guide block 584 is positioned within its corresponding guide groove 4100.

[0098] When the connecting block 581 moves, the guide groove 4100 can limit the guide block 584, so that the connecting block 581 extends along the axial direction of the blower 42 without rotating.

[0099] For example, the turntable 552 and the connecting block 581 are rotatably connected by a bearing, one side of the connecting block 581 is inserted into the inner wall of the bearing, and the turntable 552 is connected to the outer wall of the bearing.

[0100] Of course, the reset component 58 mentioned above is not limited to the structure described above. For example, the reset component 58 can be a connecting rod structure connected to a telescopic spring. The connecting rod is rotatably inserted into the turntable 552.

[0101] Combination Figure 1 In this embodiment, to facilitate the opening and closing of the box 1, the box 1 includes an outer shell 11 and a door 12, with the door 12 rotatably connected to the outer shell 11 via a hinge pin. The mounting vertical plate 21 of the mounting bracket 2 is arranged opposite to the door 12, and the fixed end of the second telescopic rod 51 is fixedly connected to one side wall of the door 12.

[0102] In this embodiment, the first elastic element 4113, the third elastic element 5531, and the fourth elastic element 582 are all telescopic springs.

[0103] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
