DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0038] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the description of a particular example will not necessarily be repeated in the description of each example. Furthermore, the present application can refer to a number of reference numerals in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and / or configurations discussed.

[0039] For the convenience of description, spatial relative terms can be used in the description to describe the relative position relationship or movement condition of one element or feature with respect to another element or feature as shown in the drawings, such as "inner", "outer", "inboard", "outboard", "under", "below", "on", "above", "front", "back", and the like. 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 drawings. For example, if the device in the drawings is flipped over or the posture is changed or the movement state is changed, the directional indications will also change accordingly, for example: the element described as "under" or "below" another element or feature will be oriented as "above" or "over" another element or feature. Therefore, the example term "below" can include both upward and downward orientations. The device can be additionally oriented (rotated by 90 degrees or in other directions) and the spatial relative relationship descriptors used in the description are interpreted accordingly.

[0040] To solve the technical problem of easy shaking during swing in the prior art, the present application provides a foot disc mechanism and a swing device, which can realize stable swing.

[0041] In a first aspect, Figures 1 to 3 The foot plate mechanism provided by the embodiment of the application comprises a foot plate body 1, a bearing connecting pipe 2, a first bearing 3 and a second bearing 4. The foot plate body 1 comprises an upper shell 10 and a lower shell 11. The lower shell 11 is disc-shaped, and the upper shell 10 is convexly arranged on the upper side of the lower shell 11. The upper shell 10 is provided with a first mounting cavity 100. The lower shell 11 is provided with a second mounting cavity 110. The first mounting cavity 100 and the second mounting cavity 110 are in communication. The upper side of the upper shell 10 is provided with a through hole 101. The bearing connecting pipe 2 is arranged in the first mounting cavity 100 and extends out of the through hole 101 at one end for connecting an external swing head mechanism and extends into the second mounting cavity 110 at the other end. The first bearing 3 is arranged in the first mounting cavity 100 and is sleeved on the bearing connecting pipe 2 and arranged close to the through hole 101. The second bearing 4 is arranged in the second mounting cavity 110 and is sleeved on the bearing connecting pipe 2.

[0042] It can be understood that the disc-shaped lower shell 11 can increase the contact area of the foot plate mechanism with the ground, and the overall conical design of the upper shell 10 can share the rotating force brought by the swing of the swing head mechanism to the lower shell 11, so that the foot plate body 1 is stable on the ground. The arrangement of the first mounting cavity 100 and the second mounting cavity 110 provides mounting space for the bearing connecting pipe 2, the first bearing 3, the second bearing 4 and related structures. The bearing connecting pipe 2 is perpendicular to the lower shell 11, which plays a role in connecting the external swing head mechanism and keeping the positions of the first bearing 3 and the second bearing 4 unchanged. When the external swing head mechanism swings, the bearing connecting pipe 2 rotates together. At this time, the first bearing 3 and the second bearing 4 not only do not affect the rotation of the bearing connecting pipe 2, but also keep the positions of the bearing connecting pipe 2 corresponding to the first mounting cavity 100 and the second mounting cavity 110 unchanged. In this way, the problem of shaking of the swing head mechanism during operation is solved, the wear of the internal structure of the mechanism is reduced, and the service life is prolonged.

[0043] As shown in Figure 2 In the technical scheme of the embodiment, a first mounting seat 30 is further included, which is annular as a whole. The first mounting seat 30 is arranged in the first mounting cavity 100 and sleeved on the first bearing 3.

[0044] It can be understood that the first mounting seat 30 provides a mounting position for the first bearing 3, so that the first bearing 3 does not deviate from the position close to the through hole 101, thereby improving the stability during operation.

[0045] As shown in Figures 1 to 3 In the technical scheme of the embodiment, a second mounting seat 40 is further included. The second mounting seat 40 is arranged in the second mounting cavity 110 and sleeved on the bearing connecting pipe 2.

[0046] As shown in Figures 1 to 3As shown, in the technical solution of this embodiment, the second mounting base 40 includes: a fixing cover 400 and a fixing plate 401; the fixing cover 400 is sleeved on the second bearing 4; the fixing plate 401 is sleeved on the bearing connecting pipe 2 and forms a bearing cavity with the fixing cover 400, and the second bearing 4 is accommodated in the bearing cavity.

[0047] Understandably, the cooperation between the fixed cover 400 and the fixed plate 401 prevents the second bearing 4 from detaching from the bearing connecting pipe 2, thereby improving the stability during operation.

[0048] like Figures 1 to 3 As shown, in the technical solution of this embodiment, the bearing connecting tube 2 includes: a first step 20 and a second step 21; the first step 20 protrudes from the outer wall of the bearing connecting tube 2 and is located below the first bearing 3; the inner ring of the first bearing 3 abuts against the first step 20; the second step 21 protrudes from the outer wall of the bearing connecting tube 2 and is located above the fixing cover 400; the fixing cover 400 abuts against the second step 21.

[0049] Understandably, the first step 20 ensures that the first bearing 3 will not slip into the second mounting cavity 110 after prolonged shaking; the second step 21 ensures that the bottom end of the bearing connecting tube 2 does not contact the bottom of the second mounting cavity 110, thus ensuring that the bearing connecting tube 2 rotates normally.

[0050] like Figure 1 Image to Figure 3 As shown, it also includes a drive device located in the second mounting cavity 110. The drive device includes a motor 5 and a transmission assembly. The motor 5 is located on the fixed plate 401. The transmission assembly is connected to the output end of the motor 5 and is connected to the bearing connecting pipe 2. The motor drives the transmission assembly to rotate the bearing connecting pipe 2.

[0051] It is understandable that when motor 5 starts, it transmits force to bearing connecting pipe 2 through transmission components, thereby driving the oscillating head mechanism to rotate.

[0052] like Figure 1 Image to Figure 3 As shown, in the technical solution of this embodiment, the transmission component includes: a first gear 60 and a second gear 61; the first gear 60 is disposed at the output end of the motor 5; the second gear 61 is disposed in the second mounting cavity 110; and is sleeved on the bearing connecting tube 2; and meshes with the first gear 60.

[0053] It is understandable that the force generated by the motor 5 can be transmitted to the bearing connecting tube 2 through the cooperation of the first gear 60 and the second gear 61, so that the bearing connecting tube 2 can rotate normally.

[0054] like Figure 1 Image to Figure 3As shown in the technical scheme of the embodiment, the lower shell 11 is provided with a recessed portion 111 recessed towards the second mounting cavity 110.

[0055] As shown in the technical scheme of the embodiment, the lower shell 11 is provided with a recessed portion 111 recessed towards the second mounting cavity 110. Figure 1 As shown in the technical scheme of the embodiment, the lower shell 11 is provided with a recessed portion 111 recessed towards the second mounting cavity 110. Figure 3 As shown in the technical scheme of the embodiment, the second mounting cavity 110 is provided with a counterweight 7 matched with the recessed portion 111.

[0056] It can be understood that the recessed portion 111 can clasp the counterweight in the second mounting cavity 110, so that the position of the counterweight is not easy to change, and the counterweight increases the overall weight of the footbath body, so that the footbath body is not inclined due to unbalanced weight when the swing head mechanism is connected.

[0057] The second aspect, as shown in the technical scheme of the embodiment, the second aspect, as shown in the technical scheme of the embodiment, Figure 3 As shown in the technical scheme of the embodiment, the lower shell 11 is provided with a recessed portion 111 recessed towards the second mounting cavity 110.
