[0056] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0058] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0059] In order to solve the technical problem in the prior art that when a counterweight base and an oscillating mechanism are set in an electrical device, the overall structural size of the electrical device will be larger, the present application provides a counterweight assembly 1, a base and an electrical device, and a concave cavity 111 is provided in the middle of the counterweight assembly 1, which can be used to install the oscillating mechanism. While reducing the overall structural size of the electrical device, it can avoid the layout of the oscillating mechanism from having an adverse effect on the layout 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 oscillating mechanism can be completely embedded in the counterweight assembly 1, preventing the oscillating mechanism from adversely affecting the overall dimensions of the body 6 and the electrical device, thereby reducing the overall height of the electrical device. When the oscillating mechanism is disposed in the concave cavity 111 of the counterweight assembly 1, its top is connected to the bottom of the body 6, and the oscillating mechanism is located outside the body 6. This does not adversely affect the layout and dimensions of other components within the body 6. For example, the size of the water tank disposed within the body can be set sufficiently large to increase the water tank capacity, reduce the frequency of water refilling during use of the electrical device, and thus improve the performance of the electrical device.

[0061] The counterweight 11 is disposed within the housing to secure the counterweight 11 and enhance the aesthetics of the counterweight assembly 1. The top of the housing has an opening 121 corresponding to the recessed cavity 111, allowing the oscillating mechanism to be installed into the recessed cavity 111 through the opening 121, thereby preventing 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 is in contact with the outer walls of the bottom and sides of the oscillating mechanism, thereby preventing the oscillating mechanism from shaking inside the cavity 111. The counterweight 11 can be an annular structure or a disc-shaped structure having the cavity 111. In either case, the cavity 111 can be formed in the middle of the counterweight 11 and the counterweight assembly 1, and the objectives of the present application can be achieved.

[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 sequence to enter the concave cavity 111.

[0064] In some embodiments of this application, please refer to Figure 1 and Figure 3The shell comprises a detachably connected top cover 12 and bottom cover 13, which can facilitate the disassembly and assembly of the counterweight 11 inside the shell. The top cover 12 is annular in structure, and an opening 121 is formed in the middle of the top cover 12. When the head shaking mechanism is installed, it can be put into the middle opening 121 of the top cover 12. When the head shaking mechanism is working normally, the moving parts in the head shaking mechanism can be prevented from interfering with the top cover 12.

[0065] In some embodiments of the present application, please refer to Figure 3 The top cover 12 is provided with a first connecting part 122, the bottom cover 13 is provided with a second connecting part 132, and the counterweight 11 is provided with a second through hole 113. The first connecting part 122 and / or the second connecting part 132 are inserted into the second through hole 113 to realize the detachable connection between the first connecting part 122 and the second connecting part 132. The shell can be assembled through the connection between the first connecting part 122 and the second connecting part 132, and the first connecting part 122 and / or the second connecting part 132 can be inserted into the second through hole 113 of the counterweight 11 to limit the movement of the counterweight 11, so that the relative position between the counterweight 11 and the shell is fixed, preventing the counterweight 11 from shaking or rotating inside the shell.

[0066] In some embodiments of the present application, please refer to Figure 3 The first connecting part 122 and the second connecting part 132 are both columnar in structure. The first connecting part 122 is provided with a blind hole type threaded hole, and the second connecting part 132 is provided with a through hole type threaded hole or a through hole. When the first connecting part 122 and the second connecting part 132 are connected, the screw can be inserted from the bottom of the bottom cover 13 and then screwed into the second connecting part 132 and the first connecting part 122 in sequence, so as to fix the bottom cover 13, the counterweight 11 and the top cover 12 as a whole.

[0067] In some embodiments of the present application, please refer to Figure 3 The number of the first connecting part 122, the second through hole 113 and the second connecting part 132 is multiple, which can form multiple connection points in the circumferential direction of the counterweight assembly 1, and realize the uniform connection of the counterweight 11 and the shell in the circumferential direction.

[0068] In some embodiments of the present application, please refer to Figure 1 and Figure 3 The bottom of the shell is provided with a plurality of casters 14, which can realize the movement of the counterweight assembly 1 and the electrical appliance. The user can transfer the electrical appliance to any space for use according to the need, which improves the use convenience of the electrical appliance and is beneficial to improving the user experience.

[0069] In some embodiments of the present application, please refer to Figure 3 and Figure 4A plurality of fourth connecting portions 133 are arranged on the bottom cover 13, which can be used to mount the casters 14. In order to reduce the gravity center of the electrical appliance, the fourth connecting portions 133 are upwardly recessed groove structures, which can realize embedded mounting of the casters 14, so that the gravity center of the counterweight assembly 1 is as close to the ground as possible, which is beneficial to improve the stability of the counterweight assembly 1.

[0070] In some embodiments of the present application, referring to Figure 2 and Figures 1 to 18 , the bottom of the counterweight 11 is provided with a second avoiding portion 115, which can be used to cooperate with the fourth connecting portion 133 on the bottom cover 13 to avoid interference between the bottom of the counterweight 11 and the fourth connecting portion 133 on the bottom cover 13.

[0071] Referring to Figure 1 , the second aspect of the embodiment of the present application provides a base, which comprises the counterweight assembly 1 described in the above embodiment, and further comprises a head-tilting mechanism, which is detachably arranged in the cavity 111. When the electrical appliance is shipped, the head-tilting mechanism is beneficial to realize separate packaging of the counterweight assembly 1 with a large outer peripheral dimension, so as to reduce the overall packaging volume of the electrical appliance.

[0072] In some embodiments of the present application, referring to Figure 3 , Figure 4 , Figure 6 and Figure 1 , the bottom cover 13 is further provided with a fifth connecting portion 134, and the head-tilting mechanism is provided with a sixth connecting portion 213. The fifth connecting portion 134 and the sixth connecting portion 213 can be connected through a connecting piece 214, so as to realize detachable connection between the head-tilting mechanism and the counterweight assembly 1.

[0073] In some embodiments of the present application, referring to Figure 3 , Figure 4 , Figure 6 and Figure 1 , the fifth connecting portion 134 and the sixth connecting portion 213 are both columnar structures. The fifth connecting portion 134 is provided with a through-hole type threaded hole or a through hole, and the sixth connecting portion 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 portion 134 and the sixth connecting portion 213 in sequence, so as to realize connection between the head-tilting mechanism and the bottom cover 13, and thus realize fixation of the head-tilting mechanism in the cavity 111.

[0074] In some embodiments of the present application, referring to Figure 3 , Figure 4 , Figure 6 and Figures 5 to 10 , the counterweight 11 is provided with a first avoiding portion 114 corresponding to the fifth connecting portion 134, which can avoid interference between the counterweight 11 and the connection between the bottom cover 13 and the head-tilting 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 set on the base assembly 2, and is used to drive the fuselage 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 Figure 8 The base assembly 2 includes a disc 21 and a rotating shaft 22. A sixth connecting portion 213 is provided on the disc 21 and can be connected to the fifth connecting portion 134 on the counterweight assembly 1, thereby achieving relative fixation between the disc 21 and the counterweight assembly 1. The disc 21 also has a power port 215 corresponding to the first through hole 131, facilitating the insertion of a power cord from the counterweight assembly 1 into the power port 215 on the disc 21.

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

[0079] A first annular step structure 211 is provided on the disc body 21, and a second annular step structure 221 is provided on the rotating shaft 22. The first annular step structure 211 surrounds the outer periphery of the second annular step structure 221, limiting the axial movement of the second annular step structure 221 on the rotating shaft 22. The first annular step structure 211 and the second annular step structure 221 are capable of relative rotation. When the rotating shaft 22 rotates relative to the disc body 21, the second annular step structure 221 also rotates relative to the first annular step structure 211. However, the first annular step structure 211 acts as an axial limiter on the second annular step structure 221, ensuring the rotational reliability of the oscillating mechanism and preventing axial deflection of the body 6 relative to the base.

[0080] In some embodiments of this application, please refer to Figure 10 and Figure 8The first annular stepped structure 211 comprises 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 stepped shape; the second annular stepped structure 221 comprises 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 stepped shape.

[0081] The first limiting surface 2111 and the fourth limiting surface 2211 are matched and arranged as a cylindrical surface or a conical surface, and 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 limit the fourth limiting surface 2211 in the radial direction. The second limiting surface 2112 and the fifth limiting surface 2212 are matched and arranged as an annular plane, and the second limiting surface 2112 is located on one side of the fifth limiting surface 2212 in the axial direction, so that the second limiting surface 2112 can limit the fifth limiting surface 2212 in the axial direction. The third limiting surface 2113 and the sixth limiting surface 2213 are matched and arranged as a cylindrical surface or a conical surface, and the third limiting surface 2113 is arranged around the outer periphery of the sixth limiting surface 2213; when the third limiting surface 2113 and the sixth limiting surface 2213 rotate relative to each other, the third limiting surface 2113 can limit the sixth limiting surface 2213 in the radial direction.

[0082] In some embodiments of the present application, referring to Figure 10 and Figure 7 The shaft 22 further comprises a seventh connecting portion 222 for connecting with the support assembly 3, the seventh connecting portion 222 can be embedded in the support assembly 3, and the cross section of the seventh connecting portion 222 is a non-circular cross section, so that the support assembly 3 and the seventh connecting portion 222 cannot rotate relative to each other, thereby achieving synchronous rotation of the support assembly 3 and the shaft 22.

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

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

[0085] In some embodiments of the present application, referring to Figure 10 and Figure 8 , the axial direction of the rotating shaft 22 is the vertical direction, and the second limiting surface 2112 is located above the fifth limiting surface 2212, so that the rotating shaft 22 cannot be pulled out from above the disc body 21, and thus the disc body 21 and the counterweight assembly 1 can be pulled up together through the rotating shaft 22 when the machine body 6 and the support assembly 3 are lifted, so that the machine body 6 and the base can not be separated during normal use of the electrical equipment.

[0086] In some embodiments of the present application, referring to Figure 10 , in order to further improve the connection reliability between the rotating shaft 22 and the support assembly 3, an eighth connecting part 224 is further arranged on the rotating shaft 22, a screw can be inserted into the eighth connecting part 224 from the bottom of the disc body 21, and the screw is fixedly connected with the bottom of the support assembly 3, so that the rotating shaft 22 and the support assembly 3 can not be separated.

[0087] In some embodiments of the present application, referring to Figure 9 , in order to further improve the axial limiting effect of the disc body 21 on the rotating shaft 22, a ring-shaped first limiting part 217 is further arranged above the first limiting surface 2111 of the disc body 21, and a second limiting part 223 matched with the first limiting part 217 is arranged above the fourth limiting surface 2211 of the rotating shaft 22, so that the first limiting part 217 can block the second limiting part 223 in the axial direction, and the rotating shaft 22 cannot be pulled out from above the disc body 21.

[0088] In some embodiments of the present application, referring to Figure 9A plurality of first protrusions 212 are evenly distributed 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, thereby increasing the rigidity of the inner circumference of the first annular step structure 211 and the load-bearing capacity of the first annular step, thereby preventing deformation of the first annular step structure 211 when mating with the second annular step structure 221. In addition, the presence of the first protrusions 212 ensures 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) maintain close contact when mating, thereby reducing the mating clearance. Even if one of the components is slightly deformed, the first protrusions 212 can compensate for it and maintain the acceptable mating 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 one of the first limiting surface 2111 and the fourth limiting surface 2211 is deformed, 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, which can improve the service life of the electrical equipment.

[0090] In some embodiments of this application, please refer to Figure 11 and Figure 9 The support assembly 3 is connected to the drive assembly 4, and the base assembly 2 is provided with a transmission part 23. The drive assembly 4 cooperates with the transmission part 23 to rotate the support assembly 3 relative to the base assembly 2, thereby realizing the rotation of the support assembly 3 and the fuselage 6 above it.

[0091] In some embodiments of this application, please refer to Figure 11 and Figure 9 The transmission part 23 is a ring gear arranged inside the disc body 21. The axis of the ring gear 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. The driving gear 41 is engaged with the ring gear. When the driving gear 41 rotates, since the ring gear remains stationary, a reaction force can be provided to the driving gear 41, causing the driving gear 41 to move around the outer periphery of the ring gear through meshing transmission, thereby driving the support assembly 3 fixedly connected to the driving assembly 4 to rotate around the axis of the ring gear.

[0092] In some embodiments of this application, please refer to Figure 11 and Figure 9The transmission portion 23 is provided with a guide portion 24 for matching with the drive assembly 4 and / or the support assembly 3, which can achieve radial positioning and rotational guidance for the support assembly 3 and the drive assembly 4 along the outer circumference of the transmission portion 23. The guide portion 24 can contact and guide one of the support assembly 3 or the drive assembly 4, or can contact and guide both the support assembly 3 and the drive assembly 4, both of which can achieve the purpose of the present application.

[0093] In some embodiments of this application, please refer to Figure 11 and Figure 7 The guide portion 24 includes a plurality of guide plates arranged in sequence 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; the outer shell of the driving component 4 is provided with an abutment surface 42 matching the guide plate. When the support component 3 and the driving component 4 rotate around the axis of the transmission portion 23, the abutment surface 42 is arranged in sliding contact with the guide plate, and the guide plate can play a role in radial positioning and rotational guidance of the abutment 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 peripheral surface of the cylindrical structure, thereby achieving the radial positioning and rotational guiding effect of the guide portion 24 on the drive component 4 and the support component 3.

[0095] In some embodiments of this application, please refer to Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 、 Figure 16 、 Figure 18 and Figures 12 to 18 The shaking 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 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 conducive to reducing the energy consumption generated by the driving component 4 to drive the support component 3 to rotate.

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

[0097] In some embodiments of the present application, referring to Figure 13 and Figure 12 , the first gasket 51 is provided with a positioning portion 511 and a third connecting portion 512.

The third connecting portion 512 is used to connect with the support assembly 3, and can fix the first gasket 51 on the circumferential edge of the support assembly 3, so as to contact with other components in the rolling assembly 5, thereby realizing the load transmission.

[0098] In some embodiments of the present application, referring to Figure 13 and Figure 12 , the positioning portion 511 is a clamping structure (such as a screw or a clamping tooth, a clamping groove, etc.) arranged on the top of the first gasket 51, which can be used to realize the positioning and matching with the support assembly 3 quickly. The third connecting portion 512 is provided with a mounting hole, and the fixed connection between the first gasket 51 and the support assembly 3 can be realized through screws or other components.

[0099] As a specific embodiment of the present application, referring to Figure 13 and Figure 12 , the positioning portion 511 is two screw caps arranged circumferentially on the first gasket 51, and the positioning and connection or separation between the first gasket 51 and the support assembly 3 can be realized by rotating the first gasket 51. The third connecting portion 512 is a connecting seat arranged on both sides of the first gasket 51, and the connecting seat is provided with a mounting hole, which can be used to realize the symmetrical connection between the two sides of the first gasket 51 and the support assembly 3.

[0100] In some embodiments of the present application, referring to Figure 13 and Figure 13A reinforcing rib structure 515 is also provided on the top of the first washer 51, which can be used to improve the structural strength of the first washer 51. When the rolling body 54 applies upward pressure to the first washer 51 and the support assembly 3, the first washer 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 Figure 14 、 Figure 18 and Figure 13 The first washer 51 and / or the second washer 53 has a rib extending axially along 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 dislocation of the entire rolling assembly 5.

[0102] In some embodiments of this application, please refer to Figure 14 、 Figure 18 and Figure 16 The first washer 51 has a first rib 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 rib 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 rib 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 rib 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 Figure 17 and Figure 16 The retaining member 52 is an annular structure, which can avoid interference with the rotating shaft 22 and the support assembly 3 in the central area of ​​the base assembly 2; a plurality of second protrusions 521 are provided on the inner circumference 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 provided 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 Figure 17 、 Figure 18 and Figure 9 The retaining member 52 is further 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 distance 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 Figure 15 and Figures 12 to 18 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 at 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 realize the axial load transmission between the support assembly 3 and the base assembly 2 through the thrust bearing, 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 are fixed in specifications and have 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 1 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, which can realize all-round air supply, cooling or heating by driving the body 6 to rotate relative to the counterweight assembly 1 through an oscillating mechanism.

[0112] In some embodiments of the present application, the electric appliance is a tower fan, the head-shaking mechanism is embedded in the recess 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 that the support assembly 3 can avoid interfering with the top cover 12 of the counterweight assembly 1 when rotating. The support assembly 3, the driving assembly 4, and the base assembly 2 in the head-shaking mechanism are all arranged outside the body 6, and do not affect the size of other components inside the body 6. For example, because the installation position of the head-shaking mechanism is transferred from the inside of the body 6 to the recess 111 of the counterweight assembly 1, the size of the water tank arranged inside the body 6 can be increased, and the capacity of the water tank can be increased, so that the frequency of water replenishment during use can be reduced, the convenience of using the tower fan is improved, and the user experience is improved.

[0113] When the electric appliance is shipped, because the head-shaking mechanism and the counterweight assembly 1 are detachably connected, the body 6 and the head-shaking mechanism with a smaller outer size (such as diameter) can be packaged as a whole, and the counterweight assembly 1 with a larger outer size can be packaged separately, so that the overall packaging volume of the electric appliance can be reduced.

[0114] In addition, the counterweight assembly 1 can be pre-assembled during production, that is, the counterweight 11, the top cover 12, the bottom cover 13, and the casters 14 are assembled, which can improve the production efficiency of the electric appliance production line. After receiving the package, the user only needs to assemble the head-shaking mechanism and the counterweight assembly 1 through the fifth connecting part 134 and the sixth connecting part 213, and then connect the body 6 and the base, so that the difficulty of self-assembly after receiving the goods by the user is reduced.

[0115] In some embodiments of the present application, please refer to Figures 1 to 18 The assembly process of the counterweight assembly 1 is as follows:

[0116] Step one: Place the counterweight 11 on the bottom cover 13, so that the second connecting part 132 is inserted into the second through hole 113 to position the counterweight 11 and the bottom cover 13;

[0118] Step three: Assemble the casters 14 on the fourth connecting part 133 of the bottom cover 13.

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

[0120] Step one: insert the rotating shaft 22 from the bottom of the disc body 21, so that the seventh connecting part 222 extends out of the first annular step structure 211, to connect with the support assembly 3;

[0121] Step two: connect the second gasket 53 with the disc body 21, and place the retaining member 52 and the rolling body 54 on the second gasket 53;

[0122] Step three: connect the support assembly 3 with the machine body 6, the driving assembly 4 and the first gasket 51 respectively;

[0123] Step four: connect the support assembly 3 with the seventh connecting part 222, so that the first gasket 51 contacts with the rolling body 54, the driving assembly 4 engages with the transmission part 23, and the rotating shaft 22 is fixedly connected with the support assembly 3 through the eighth connecting part 224.

[0124] In some embodiments of the present application, please refer to ​ The assembling process of the above base is as follows:

[0125] Step one: put the swing mechanism at the bottom of the machine body 6 into the concave cavity 111 of the counterweight assembly 1;

[0126] Step two: extend the connecting part 214 from the bottom of the bottom cover 13 into the fifth connecting part 134, to realize the fixed connection between the fifth connecting part 134 of the bottom cover 13 and the sixth connecting part 213 of the disc body 21.
