[0056] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0057] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0058] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0059] In order to solve the technical problem in the prior art that setting a counterweight base and an shaking head mechanism in an electrical device will cause the overall structural size of the electrical device to be larger, the present application provides a counterweight assembly 1, a base and an electrical device, wherein a concave cavity 111 is provided in the middle of the counterweight assembly 1, which can be used to install the shaking head mechanism. While reducing the overall structural size of the electrical device, it can avoid that the arrangement of the shaking head mechanism has an adverse effect on the arrangement and size of other components inside the fuselage 6.

[0060] See also Figures 1 to 18 In a first aspect, the present invention provides a weight assembly 1, comprising a weight member 11 and a housing. The middle portion of the weight member 11 has a concave cavity 111 for mounting a shaking mechanism, such as Figure 1 , Figure 5 and Figure 6As shown, the shaking mechanism can be completely embedded in the counterweight assembly 1, avoiding the adverse effect of the setting of the shaking mechanism on the overall size of the fuselage 6 and the electrical equipment, which is conducive to reducing the overall height of the electrical equipment. When the shaking mechanism is set in the concave cavity 111 of the counterweight assembly 1, its top is connected to the bottom of the fuselage 6, and the shaking mechanism is located on the outside of the fuselage 6. There is no adverse effect on the layout and size of other components inside the fuselage 6. For example, the size of the water tank set inside the fuselage can be set large enough to increase the capacity of the water tank, reduce the frequency of water replenishment of the electrical equipment during use, and help improve the performance of the electrical equipment.

[0061] The counterweight 11 is disposed inside the housing, and can be used to fix the counterweight 11 and improve the appearance of the counterweight assembly 1. An opening 121 corresponding to the cavity 111 is provided on the top of the housing, so that the oscillating mechanism can be installed into the cavity 111 from the opening 121 to avoid interference between the housing and the oscillating mechanism.

[0062] It should be noted that the shape and size of the cavity 111 are set according to the external shape and size of the oscillating mechanism, so that the inner wall of the cavity 111 fits with the outer wall of the bottom and side of the oscillating mechanism to prevent the oscillating mechanism from shaking inside the cavity 111. The counterweight 11 can be an annular structure or a disc-shaped structure with the cavity 111, and both can form the cavity 111 in the middle of the counterweight 11 and the counterweight assembly 1, and both can achieve the purpose of the present application.

[0063] In some embodiments of this application, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The counterweight 11 is provided with a wire groove 112, which is connected to the concave cavity 111, so that the power cord can pass through the counterweight 11 and enter the concave cavity 111 to achieve electrical connection with the power supply module in the shaking mechanism; since the counterweight assembly 1 is usually set on the ground, the external power cord is led out through the counterweight assembly 1, which can reduce the height of the power cord from the ground, making it less susceptible to external interference or damage, thereby improving the stability and reliability of the electrical equipment. The shell has a first through hole 131 corresponding to the wire groove 112, so that the power cable can pass through the shell and the wire groove 112 in turn to enter the concave cavity 111.

[0064] In some embodiments of this application, please refer to Figure 1 and Figure 3The housing includes a detachably connected top cover 12 and bottom cover 13, which can facilitate the disassembly and assembly of the counterweight 11 inside the housing. The top cover 12 is a ring-shaped structure, and an opening 121 is formed in the middle of the top cover 12. When the oscillating mechanism is installed, it can be inserted through the middle opening 121 of the top cover 12; when the oscillating mechanism works normally, the moving parts in the oscillating mechanism can be prevented from interfering with the top cover 12.

[0065] In some embodiments of this application, please refer to Figure 3 A first connecting portion 122 is provided on the top cover 12, a second connecting portion 132 is provided on the bottom cover 13, and a second through hole 113 is provided on the counterweight 11. The first connecting portion 122 and / or the second connecting portion 132 are inserted into the second through hole 113 to achieve a detachable connection between the first connecting portion 122 and the second connecting portion 132. The shell can be assembled through the connection between the first connecting portion 122 and the second connecting portion 132, and the counterweight 11 can be moved and limited by inserting the first connecting portion 122 and / or the second connecting portion 132 into the second through hole 113 of the counterweight 11, so that the relative position between the counterweight 11 and the shell is kept fixed to prevent the counterweight 11 from shaking or rotating inside the shell.

[0066] In some embodiments of this application, please refer to Figure 3 The first connection part 122 and the second connection part 132 are both columnar structures. A blind hole type threaded hole is provided in the first connection part 122, and a through hole type threaded hole or a through hole is provided in the second connection part 132. When connecting the first connection part 122 and the second connection part 132, screws can be inserted from the bottom of the bottom cover 13 and screwed into the second connection part 132 and the first connection part 122 in turn, so as to realize the overall fixation of the bottom cover 13, the counterweight 11 and the top cover 12.

[0067] In some embodiments of this application, please refer to Figure 3 The number of the first connection part 122, the second through hole 113 and the second connection part 132 are all multiple, which can be used to form multiple connection points on the circumference of the counterweight assembly 1 to achieve uniform connection between the counterweight 11 and the shell on the circumference.

[0068] In some embodiments of this application, please refer to Figure 1 and Figure 3 A plurality of casters 14 are provided at the bottom of the shell, and the casters 14 can be used to move the counterweight assembly 1 and the electrical equipment, so that the user can transfer the electrical equipment to any space for use as needed, thereby improving the convenience of using the electrical equipment and helping to improve the user experience.

[0069] In some embodiments of this application, please refer to Figure 3 and Figure 4A plurality of fourth connection parts 133 are provided on the bottom cover 13, which can be used to realize the installation of the caster 14. In order to lower the center of gravity of the electrical equipment, the fourth connection part 133 is an upwardly concave groove structure, which can realize the embedded installation of the caster 14, so that the center of gravity of the counterweight assembly 1 is as close to the ground as possible, which is beneficial to improving the stability of the counterweight assembly 1.

[0070] In some embodiments of this application, please refer to Figure 2 and Figure 3 A second avoidance portion 115 is provided at the bottom of the counterweight 11 , which can be used to cooperate with the fourth connection portion 133 on the bottom cover 13 to avoid interference between the bottom of the counterweight 11 and the fourth connection portion 133 on the bottom cover 13 .

[0071] See also Figures 1 to 18 The second aspect of the embodiment of the present application provides a base, including the counterweight assembly 1 described in the above embodiment, and also includes a shaking head mechanism, which is detachably arranged inside the cavity 111. When shipping the electrical equipment, it is beneficial to realize the separate packaging of the counterweight assembly 1 with a larger outer peripheral size, which can reduce the overall packaging volume of the electrical equipment.

[0072] In some embodiments of this application, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 A fifth connecting portion 134 is also provided on the bottom cover 13, and a sixth connecting portion 213 is provided on the shaking mechanism. The fifth connecting portion 134 and the sixth connecting portion 213 can be connected through the connecting piece 214, thereby realizing a detachable connection between the shaking mechanism and the counterweight assembly 1.

[0073] In some embodiments of this application, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The fifth connecting part 134 and the sixth connecting part 213 are both columnar structures. The fifth connecting part 134 is provided with a through-hole type threaded hole or a through hole, and the sixth connecting part 213 is provided with a blind hole type threaded hole. The connecting piece 214 extends from the bottom of the bottom cover 13 and is screwed into the fifth connecting part 134 and the sixth connecting part 213 in turn to realize the connection between the shaking head mechanism and the bottom cover 13, thereby realizing the fixation of the shaking head mechanism inside the concave cavity 111.

[0074] In some embodiments of this application, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 The counterweight 11 has a first avoidance portion 114 corresponding to the fifth connection portion 134, which can prevent the counterweight 11 from interfering with the connection between the bottom cover 13 and the shaking mechanism.

[0075] In some embodiments of the present application, the fifth connecting portion 134, the sixth connecting portion 213, the first avoidance portion 114 and the connecting member 214 are all multiple in number, and multiple connection points can be formed in the circumferential direction of the shaking head mechanism, so that the shaking head mechanism and the counterweight assembly 1 are evenly connected in the circumferential direction.

[0076] In some embodiments of this application, please refer to Figures 5 to 10 The shaking head mechanism includes a base assembly 2 and a support assembly 3. The base assembly 2 is detachably connected to the counterweight assembly 1 and can be used as a fixed part in the shaking head mechanism to achieve a fixed connection with the counterweight assembly 1; the support assembly 3 is rotatably arranged on the base assembly 2, and is used to drive the body 6 to rotate relative to the base, thereby realizing the shaking head function of the electrical equipment, so as to facilitate all-round air supply, cooling or heating.

[0077] In some embodiments of this application, please refer to Figures 5 to 10 The base assembly 2 includes a disc 21 and a rotating shaft 22. The sixth connecting portion 213 is arranged on the disc 21 and can be connected to the fifth connecting portion 134 on the counterweight assembly 1, so as to achieve relative fixation between the disc 21 and the counterweight assembly 1. The disc 21 is also provided with a power interface 215 corresponding to the first through hole 131, so that the power cord can be inserted from the counterweight assembly 1 and connected to the power interface 215 on the disc 21.

[0078] The rotating shaft 22 is rotatably connected to the disk body 21, and the supporting assembly 3 is connected to the rotating shaft 22 and the supporting assembly 3 and the rotating shaft 22 can rotate synchronously, so that the supporting assembly 3 rotates relative to the disk body 21 and the counterweight assembly 1, and then the fuselage 6 fixed above the supporting assembly 3 rotates relative to the base.

[0079] The disk body 21 is provided with a first annular step structure 211, and the rotating shaft 22 is provided with a second annular step structure 221. The first annular step structure 211 is arranged around the outer periphery of the second annular step structure 221 to limit the axial movement of the second annular step structure 221 in the rotating shaft 22; and the first annular step structure 211 and the second annular step structure 221 can rotate relative to each other. When the rotating shaft 22 rotates relative to the disk body 21, the second annular step structure 221 also rotates relative to the first annular step structure 211, but the first annular step structure 211 has an axial limiting effect on the second annular step structure 221, which can ensure the rotation reliability of the shaking mechanism and prevent the body 6 from being axially deflected relative to the base.

[0080] In some embodiments of this application, please refer to Figure 8 and Fig.10The first annular step structure 211 includes a first limiting surface 2111, a second limiting surface 2112 and a third limiting surface 2113, and the first limiting surface 2111, the second limiting surface 2112 and the third limiting surface 2113 are connected in a step shape; the second annular step structure 221 includes a fourth limiting surface 2211, a fifth limiting surface 2212 and a sixth limiting surface 2213, and the fourth limiting surface 2211, the fifth limiting surface 2212 and the sixth limiting surface 2213 are connected in a step shape.

[0081] The first limiting surface 2111 is matched with the fourth limiting surface 2211 and can be a cylindrical surface or a conical surface. The first limiting surface 2111 is arranged around the outer periphery of the fourth limiting surface 2211. When the first limiting surface 2111 and the fourth limiting surface 2211 rotate relative to each other, the first limiting surface 2111 can radially limit the fourth limiting surface 2211. The second limiting surface 2112 is matched with the fifth limiting surface 2212 and is an annular plane. The second limiting surface 2112 is located on one side of the fifth limiting surface 2212 in the axial direction, and the fifth limiting surface 2212 can be axially limited by the second limiting surface 2112. The third limiting surface 2113 is matched with the sixth limiting surface 2213 and can be a cylindrical surface or a conical surface. The third limiting surface 2113 is arranged around the outer circumference of the sixth limiting surface 2213. When relative rotation occurs between the third limiting surface 2113 and the sixth limiting surface 2213, the third limiting surface 2113 can realize radial limitation of the sixth limiting surface 2213.

[0082] In some embodiments of this application, please refer to Figure 8 and Fig.10 The rotating shaft 22 also has a seventh connecting portion 222 for connecting to the supporting assembly 3. The seventh connecting portion 222 can be embedded in the supporting assembly 3, and the cross-section of the seventh connecting portion 222 is a non-circular cross-section, which can avoid relative rotation between the supporting assembly 3 and the seventh connecting portion 222, thereby realizing synchronous rotation of the supporting assembly 3 and the rotating shaft 22.

[0083] In some embodiments of the present application, the cross-section of the first connection portion 122 is D-shaped or strip-shaped, both of which can achieve the purpose of the present application.

[0084] In the above embodiment, since the rotating shaft 22 mainly realizes relative rotation cooperation with the disk body 21 through the fourth limiting surface 2211, it is necessary to ensure that the fourth limiting surface 2211 has a sufficiently large area to realize rotational contact and radial limitation with the disk body 21; and the rotating shaft 22 is mainly connected to the support assembly 3 through the seventh connecting part 222, and the connection area between the seventh connecting part 222 and the support assembly 3 must be guaranteed. Therefore, in the axial direction of the rotating shaft 22, the height of the fourth limiting surface 2211 accounts for 2 / 5-1 / 2 of the height of the rotating shaft 22, and is kept close to or consistent with the height of the seventh connecting part 222 as much as possible. The reliability and stability of the axial positioning between the disk body 21 and the support assembly 3 can be improved through the rotating shaft 22.

[0085] In some embodiments of this application, please refer to Figure 7 and Fig.10 The axial direction of the rotating shaft 22 is in the vertical direction, and the second limiting surface 2112 is located above the fifth limiting surface 2212, which can prevent the rotating shaft 22 from escaping from the top of the disk body 21, so that when the fuselage 6 and the supporting assembly 3 are lifted, the disk body 21 and the counterweight assembly 1 can be pulled up together through the rotating shaft 22, thereby preventing the fuselage 6 from being separated from the base during normal use of the electrical equipment.

[0086] In some embodiments of this application, please refer to Figure 8 In order to further improve the connection reliability between the rotating shaft 22 and the supporting assembly 3, an eighth connecting portion 224 is also provided on the rotating shaft 22. The screws can be extended into the eighth connecting portion 224 from the bottom of the disk body 21, and fixedly connected with the bottom of the supporting assembly 3 by the screws, thereby avoiding separation between the rotating shaft 22 and the supporting assembly 3.

[0087] In some embodiments of this application, please refer to Fig.10 In order to further enhance the axial limiting effect of the disk body 21 on the rotating shaft 22, a first annular limiting portion 217 is provided above the first limiting surface 2111 of the disk body 21, and a second limiting portion 223 matching the first limiting portion 217 is provided above the fourth limiting surface 2211 of the rotating shaft 22. The first limiting portion 217 can block the second limiting portion 223 in the axial direction to prevent the rotating shaft 22 from falling out from the top of the disk body 21.

[0088] In some embodiments of this application, please refer to Fig. 9A plurality of first protrusions 212 are evenly arranged on the inner circumference of the first annular step structure 211. The first protrusions 212 are used to contact the outer circumference of the second annular step structure 221, which can improve the rigidity of the inner circumference of the first annular step structure 211, improve the bearing capacity of the first annular step, and avoid deformation of the first annular step structure 211 when it is matched with the second annular step structure 221. In addition, the existence of the first protrusions 212 can ensure that the two surfaces (i.e., the inner circumference of the first annular step structure 211 and the outer circumference of the second annular step structure 221) can maintain close contact when they are matched, thereby reducing the matching clearance. Even if one of the components is slightly deformed, the first protrusion 212 can play a compensatory role to maintain the qualification of the matching clearance.

[0089] In some embodiments of the present application, the first protrusion 212 is a vertical rib arranged on the first limiting surface 2111, which can be used to contact and cooperate with the fourth limiting surface 2211 in the second annular step structure 221. Even if there is deformation in one of the first limiting surface 2111 and the fourth limiting surface 2211, the fitting clearance compensation can be achieved through multiple first protrusions 212 (i.e., vertical ribs), so that the first annular step structure 211 and the second annular step structure 221 can maintain normal relative rotation, thereby improving the service life of the electrical equipment.

[0090] In some embodiments of this application, please refer to Fig. 9 and Fig.11 The support assembly 3 is connected to the driving assembly 4, and the base assembly 2 is provided with a transmission part 23.

[0091] In some embodiments of this application, please refer to Fig. 9 and Fig.11 The transmission part 23 is a gear ring arranged inside the disc body 21, and the axis of the gear ring coincides with the axis of the rotating shaft 22. The driving assembly 4 includes a driving gear 41 connected to a rotating driving member such as a motor, and the driving gear 41 is meshed with the gear ring. When the driving gear 41 rotates, since the gear ring remains stationary, a reaction force can be provided to the driving gear 41, so that the driving gear 41 moves on the outer periphery of the gear ring through meshing transmission, thereby driving the supporting assembly 3 fixedly connected to the driving assembly 4 to rotate around the axis of the gear ring.

[0092] In some embodiments of this application, please refer to Fig. 9 and Fig.11The transmission part 23 is provided with a guide part 24 for matching with the driving assembly 4 and / or the supporting assembly 3, which can realize radial positioning and rotational guidance for the supporting assembly 3 and the driving assembly 4 along the outer periphery of the transmission part 23. The guide part 24 can be contacted and guided with one of the supporting assembly 3 or the driving assembly 4, or can be contacted and guided with both the supporting assembly 3 and the driving assembly 4 at the same time, both of which can achieve the purpose of the present application.

[0093] In some embodiments of this application, please refer to Fig. 9 and Fig.11 The guide portion 24 includes a plurality of guide plates sequentially arranged along the circumference of the transmission portion 23, and the guide plates have an arc-shaped guide surface facing the outer periphery of the transmission portion 23; a contact surface 42 matching the guide plate is provided on the outer shell of the driving component 4, and when the supporting component 3 and the driving component 4 rotate around the axis of the transmission portion 23, the contact surface 42 is arranged in sliding contact with the guide plate, and the guide plate can play a role in radial positioning and rotational guiding of the contact surface 42 of the driving component 4.

[0094] In other embodiments of the present application, the guide portion 24 may also be a complete cylindrical structure, so that the abutment surface 42 can always maintain contact with the outer circumferential surface of the cylindrical structure, thereby achieving the radial positioning and rotational guiding effect of the guide portion 24 on the drive assembly 4 and the support assembly 3.

[0095] In some embodiments of this application, please refer to Figure 7 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 and Fig.18 The shaking head mechanism also includes a rolling component 5, which is respectively connected to the base component 2 and the support component 3, and is used to reduce the relative rotational resistance between the base component 2 and the support component 3, so that the shaking head mechanism can operate more smoothly and efficiently, and can ensure the rotational stability and accuracy of the support component 3 and the fuselage 6, which is beneficial to reduce the energy consumption generated by the driving component 4 driving the support component 3 to rotate.

[0096] In some embodiments of this application, please refer to Figures 12 to 18The rolling assembly 5 includes a first washer 51, a retaining member 52, a second washer 53 and a plurality of rolling bodies 54. The first washer 51 is connected to the circumferential edge of the support assembly 3, the second washer 53 is connected to the circumferential edge of the base assembly 2, the retaining member 52 is arranged between the first washer 51 and the second washer 53, and a plurality of rolling bodies 54 are movably arranged on the retaining member 52. The rolling bodies 54 are in rolling contact with the first washer 51 and the second washer 53 respectively. The support assembly 3 evenly disperses the gravity of the fuselage 6 on the first washer 51, and transmits it to the base assembly 2 through the rolling bodies 54 and the second washer 53, thereby realizing the axial load transmission between the support assembly 3 and the base assembly 2, thereby realizing the bearing of the support assembly 3 and the fuselage 6 above it through the base assembly 2.

[0097] In some embodiments of this application, please refer to Fig.12 and Fig.13 The first washer 51 is provided with a positioning portion 511 and a third connecting portion 512.

[0098] In some embodiments of this application, please refer to Fig.12 and Fig.13 The positioning portion 511 is a snap-fit ​​structure (such as a buckle or a latch, a slot, etc.) arranged on the top of the first washer 51, which can be used to quickly achieve positioning and matching with the support component 3; the third connecting portion 512 is provided with a mounting hole, and a fixed connection between the first washer 51 and the support component 3 can be achieved by screws and other components.

[0099] As a specific embodiment of this application, please refer to Fig.12 and Fig.13 The positioning portion 511 is two screw buckles arranged on the circumference of the first washer 51, and the first washer 51 can be rotated to achieve positioning connection or separation with the support assembly 3. The third connection portion 512 is a connection seat arranged on both sides of the first washer 51. The connection seat is provided with mounting holes, which can be used to achieve symmetrical connection between the two sides of the first washer 51 and the support assembly 3.

[0100] In some embodiments of this application, please refer to Fig.12 and Fig.13A reinforcing rib structure 515 is also provided on the top of the first gasket 51, which can be used to improve the structural strength of the first gasket 51. When the rolling body 54 applies upward pressure to the first gasket 51 and the support assembly 3, the first gasket 51 can withstand a larger pressure to avoid damage to the support panel in the support assembly 3 (i.e., the panel used to connect with the fuselage 6) and affect the appearance of the base.

[0101] In some embodiments of this application, please refer to Fig.13 , Fig.14 and Fig.18 The first washer 51 and / or the second washer 53 has a rib extending along the axial direction of the rolling assembly 5, which is used to limit the retaining member 52 in the radial direction of the rolling assembly 5, prevent the retaining member 52 and the rolling body 54 from moving in the radial direction, and avoid misalignment of the rolling assembly 5 as a whole.

[0102] In some embodiments of this application, please refer to Fig.13 , Fig.14 and Fig.18 The first washer 51 has a first flange 513 on its inner periphery, which can be used to radially limit the inner periphery of the retainer 52; the first washer 51 has a second flange 514 on its outer periphery, which can be used to radially limit the outer periphery of the retainer 52. The second washer 53 has a third flange 531 on its inner periphery, which can be used to radially limit the inner periphery of the retainer 52; the second washer 53 has a fourth flange 532 on its outer periphery, which can be used to radially limit the outer periphery of the retainer 52.

[0103] In some embodiments of this application, please refer to Fig.16 and Fig.17 The retaining member 52 is an annular structure, which can avoid interference with the rotating shaft 22 and the supporting assembly 3 in the central area of ​​the base assembly 2; a plurality of second protrusions 521 are provided on the inner circumferential surface of the retaining member 52, which can be used to strengthen the structural strength of the retaining member 52 and avoid deformation of the retaining member 52 during use, which affects the normal use of the rolling assembly 5.

[0104] In some embodiments of the present application, the second protrusion 521 is a vertical rib disposed on the inner circumference of the retaining member 52 , which is easy to manufacture and can reduce the difficulty of manufacturing the retaining member 52 .

[0105] In some embodiments of this application, please refer to Fig.16 , Fig.17 and Fig.18 The retaining member 52 is also provided with a third limiting portion 522 which can be used to limit the outer surface of the rolling body 54 to prevent the rolling body 54 from detaching from the retaining member 52 .

[0106] As a specific embodiment of the present application, the rolling body 54 is a sphere, and two third limiting portions 522 are arranged on both sides of the top of the rolling body 54, and the minimum spacing between the two third limiting portions 522 is smaller than the diameter of the rolling body 54, which can prevent the rolling body 54 from escaping from the top of the retaining member 52, so that the retaining member 52 and the rolling body 54 always maintain contact and move synchronously during operation.

[0107] In some embodiments of this application, please refer to Fig. 9 and Fig.15 In order to achieve a quick connection between the second gasket 53 and the base assembly 2, a first clamping portion 216 is provided on the circumference of the disk body 21, and a second clamping portion 533 is provided on the second gasket 53. The first clamping portion 216 and the second clamping portion 533 are matched with each other to achieve a quick connection between the second gasket 53 and the disk body 21.

[0108] As a specific embodiment of the present application, two first clamping portions 216 are provided on the circumference of the disk body 21, and two second clamping portions 533 are correspondingly provided on the bottom of the second gasket 53, wherein the first clamping portion 216 is a clamping groove, and the second clamping portion 533 is a clamping tooth, and a quick clamping connection between the disk body 21 and the second gasket 53 can be achieved through the clamping groove and the clamping tooth.

[0109] It should be noted that the rolling assembly 5 can adopt the thrust bearing in the prior art, and the thrust bearing is used to realize the axial load transmission between the support assembly 3 and the base assembly 2, so as to realize the bearing of the support assembly 3 and the fuselage 6 above it through the base assembly 2. However, since the existing thrust bearings have fixed specifications and no connection parts on the surface, they can only be fixed by bonding or embedding, which is not convenient for connecting with the support assembly 3 and the base assembly 2. Therefore, the present application preferably adopts the following method: Figures 12 to 18 The rolling assembly 5 shown is used to achieve load transfer between the support assembly 3 and the base assembly 2 .

[0110] See also Figures 1 to 18 The third aspect of the embodiment of the present application provides an electrical device, including the base described in the above embodiment. Since the shaking mechanism is embedded in the central concave cavity 111 of the counterweight assembly 1, the overall height of the electrical device can be reduced, thereby reducing the overall structural size and space occupancy of the electrical device.

[0111] In some embodiments of the present application, the electrical device may be a vertical fan, a vertical heater or the like, and the shaking mechanism drives the body 6 to rotate relative to the counterweight assembly 1, thereby achieving all-round air supply, cooling or heating.

[0112] In some embodiments of the present application, the electrical device is a tower fan, and the shaking mechanism is embedded in the concave cavity 111 of the counterweight assembly 1, and the support panel of the support assembly 3 is separated from the top cover 12 of the counterweight assembly 1, so as to avoid interference between the support assembly 3 and the top cover 12 of the counterweight assembly 1 when the support assembly 3 rotates. The support assembly 3, the drive assembly 4 and the base assembly 2 in the shaking mechanism are all arranged on the outside of the fuselage 6, and will not affect the size of other components inside the fuselage 6. For example, since the installation position of the shaking mechanism is transferred from the inside of the fuselage 6 to the concave cavity 111 of the counterweight assembly 1, the size of the water tank arranged inside the fuselage 6 can be increased, and the capacity of the water tank is increased, which can reduce the frequency of water replenishment during use, improve the convenience of using the tower fan, and help improve the user experience.

[0113] When shipping electrical equipment, since the shaking mechanism and the counterweight assembly 1 are detachably connected, the body 6 and the shaking mechanism with smaller outer peripheral dimensions (such as diameter, etc.) can be packaged as a whole, and the counterweight assembly 1 with larger outer peripheral dimensions can be packaged separately, which can reduce the overall packaging box volume of the electrical equipment.

[0114] In addition, the counterweight assembly 1 can be pre-installed during production, that is, the assembly of the counterweight 11, top cover 12, bottom cover 13 and casters 14 is completed, which can improve the production efficiency of the electrical equipment production line. After receiving the package, the user only needs to assemble the shaking head mechanism and the counterweight assembly 1 through the fifth connecting part 134 and the sixth connecting part 213 to achieve the connection between the fuselage 6 and the base, which reduces the difficulty of self-assembly for users after receiving the goods.

[0115] In some embodiments of this application, please refer to Figures 1 to 18 , the assembly process of the above-mentioned counterweight assembly 1 is as follows:

[0116] Step 1: Place the counterweight 11 on the bottom cover 13, insert the second connecting portion 132 into the second through hole 113, and achieve positioning between the counterweight 11 and the bottom cover 13;

[0118] Step 3: Assemble the caster 14 on the fourth connecting portion 133 of the bottom cover 13 .

[0119] In some embodiments of this application, please refer to Figures 1 to 18 , the assembly process of the above shaking mechanism is as follows:

[0120] Step 1: Insert the rotating shaft 22 from the bottom of the disc body 21 so that the seventh connecting portion 222 extends out of the first annular step structure 211 to facilitate connection with the supporting assembly 3;

[0121] Step 2: Connect the second washer 53 to the disc body 21, and place the retaining member 52 and the rolling body 54 on the second washer 53;

[0122] Step 3: Connect the support assembly 3 to the body 6, the drive assembly 4 and the first gasket 51 respectively;

[0123] Step 4: Connect the support assembly 3 to the seventh connection part 222 , so that the first washer 51 contacts the rolling body 54 , the drive assembly 4 engages with the transmission part 23 , and a fixed connection between the rotating shaft 22 and the support assembly 3 is achieved through the eighth connection part 224 .

[0124] In some embodiments of this application, please refer to Figures 1 to 18 , the assembly process of the above base is as follows:

[0125] Step 1: Place the shaking mechanism at the bottom of the fuselage 6 into the concave cavity 111 of the counterweight assembly 1;

[0126] Step 2: Extend the connecting member 214 from the bottom of the bottom cover 13 into the fifth connecting portion 134 to achieve a fixed connection between the fifth connecting portion 134 of the bottom cover 13 and the sixth connecting portion 213 of the disk body 21 .
