[0002] The prior art foldable footbath, such as patent CN217885838U, adopts multi-stage support members to form a multi-stage telescopic mechanism. When the multi-stage telescopic mechanism is extended, the footbath can be opened, and the user can use it for foot soaking and massage. When the multi-stage telescopic mechanism is retracted, the footbath can be folded for easy storage. The adjacent cylinders of the telescopic mechanism are nested and can be relatively telescopic. The support member at the lower end of the footbath is arranged on the seat body and is rotatably connected to the drive assembly. Since the lower end support member is rotatably connected to the drive assembly, it does not form a relatively fixed connection with the seat body, and the lower end support member as the main support end is not well fixed, resulting in the overall instability of the telescopic mechanism and easy shaking.

[0030] Although the present invention can be easily embodied in different forms of embodiments, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to that described herein.

[0031] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the utility model, rather than implying that each embodiment of the utility model must have the described feature. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0032] In the embodiments shown in the drawings, the directions (such as up, down, inside, outside, left, right, front, back, etc.) used to explain the structure and movement of the various components of the present invention are not absolute but relative. These descriptions are appropriate when these components are in the positions shown in the drawings. If the description of the positions of these components changes, the directions will also change accordingly.

[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these example embodiments are provided so that the description of the utility model will be more comprehensive and complete, and the concepts of the example embodiments will be fully conveyed to those skilled in the art. The accompanying drawings are only schematic illustrations of the utility model and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted.

[0034] The preferred implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings of this specification.

[0035] The utility model is a foot bath that is convenient to fold and store, referring to Figures 1 to 8 As shown, it includes a seat body 3, an upper body 1 and a fuselage 2, the fuselage 2 is respectively connected to the seat body 3 and the upper body 1, the fuselage 2 includes a flexible portion 21, a telescopic mechanism 4 is provided between the seat body 3 and the upper body 1, the telescopic mechanism 4 includes a first support member 41, a second support member 42 and a third support member 43, one of the first support member 41 and the third support member 43 is fixedly connected to the seat body 3, and the other is fixedly connected to the upper body 1, the second support member 42 is located between the first support member 41 and the third support member 43, the second support member 42 is respectively connected to the first support member 41 and the third support member 43, so that when the second support member 42 rotates, the first support member 41 and the second support member 42 can move upward or downward in the height direction of the foot bath. When the telescopic mechanism 4 is extended, the second support member 42 rotates and drives the first support member 41 to move upward along the axial direction of the third support member. At the same time, the first support member 41 moves along the axial direction of the second support member 42 to extend from the second support member 42, and the flexible portion 21 unfolds to open the footbath. When the telescopic mechanism 4 is in a retracted state, the first support member 41 and the third support member 43 are both stored inside the second support member 42, and the flexible portion 21 can be folded to fold and store the footbath. When the footbath is placed normally, the axial direction of the third support member and the axial direction of the second support member are both the height direction of the footbath, and the height direction of the footbath is shown above and below. Figure 1 shown.

[0036] like Figure 1As shown, the third support member 43 is fixedly connected to the seat body 3, and the first support member 41 is fixedly connected to the upper body 1. The fixed connection here refers to an inactive connection, that is, the connection between the third support member and the seat body is immovable, and does not rotate or move. After the first support member is fixedly connected to the upper body, it cannot rotate relative to the upper body. The first support member can only move up and down relatively along the height direction of the foot bath but does not rotate, thereby limiting the rotation of the first support member and the third support member at the upper and lower ends of the telescopic mechanism. The positions of the first support member 41 and the third support member 43 can be interchangeable, that is, the first support member 41 can be fixedly connected to the seat body 3 at the lower end, and the third support member 43 can be fixedly connected to the upper body 1 at the upper end.

[0037] In the embodiment of the utility model, the first support member and the third support member are fixedly connected to the base body and the upper body respectively, thereby reducing the instability problems such as shaking and deviation caused by the active matching clearance between the telescopic mechanism and the external structural member, and improving the tightness and stability of the matching between the support member and the external structural member. Compared with the rotatable active connection of the first support member and / or the third support member in the prior art, the foot bath of the present application has more stable and reliable performance during the folding and opening process and in the open state.

[0038] Specifically, the seat body 3 is formed with an installation cavity 31, and the installation cavity 31 is located below the foot bath cavity 22. One end of the first support member 41 or the third support member 43 fixedly connected to the seat body 3 is fixed to the bottom of the installation cavity 31. The support member can usually be fixed by a screw or a buckle structure. For example, it can be directly screwed to the screw hole on the bottom wall of the installation cavity 31 of the seat body 3 or to the screw column connected to the bottom wall. Such an assembly structure is simple, and the first support member or the third support member can be fixed to avoid rotation and other activities, thereby improving the stability of the telescopic mechanism; and when the support member is connected to the bottom of the installation cavity, the telescopic mechanism can be lowered into the installation cavity when retracted to avoid interfering with the lowering of the upper body, so that the foot bath can be folded to a very low height for easy storage, such as being placed under a bed. The first support member 41 or the third support member 43 can also be fixedly connected to the upper body 1 by a screw or a buckle structure.

[0039] The upper body 1 is a structural member made of hard materials such as an upper cover, an upper cover bottom plate 11, a plate body or a crossbeam arranged at the upper end of the foot bath.

[0040] Specifically, Figure 1 and Figure 4 As shown, the first support member 41 is provided with a first connecting plate 413, which is connected to the upper cover bottom plate 11 of the upper body 1, thereby fixing the first support member 41 to the upper body 1. The third support member 43 is provided with a third connecting plate 434, which is fixed to the bottom wall of the installation cavity 31, thereby fixing the third support member 43 to the seat body 33.

[0041] The foot bath is provided with a massage component 92, which can be used for massage when the foot bath is turned on for foot soaking. A massage drive 91 is provided in the installation cavity 31, and a transmission gear of the massage drive 91 is connected to the massage component 92. The massage component 92 is located in the installation cavity or the foot bath cavity 22 and can act on the human foot. The massage drive 91 is used to drive the massage component 92 to move to massage the foot. Among them, the massage component 92 is usually a massage wheel for massaging the sole of the foot, or it can be an air bag for massaging the sole of the foot or the instep, etc., then the corresponding massage drive 91 can be a drive motor and a transmission gear 7, and the massage drive can be an air pump for inflating the air bag in the air bag massage mode. Since the massage component moves during massage, if the foot bath itself is unstable in structure, it will cause severe shaking during massage, making the user feel unstable and unsafe. Since the foot bath of this embodiment adopts a reliable and stable telescopic mechanism, there will be no shaking problem during massage.

[0042] The body 2 of the foot bath is enclosed to form a foot bath cavity 22. Since one end of the telescopic mechanism 4 is connected to the seat body 3 and the other end is connected to the upper body 1, the telescopic mechanism 4 needs to pass through the bottom wall of the foot bath cavity 22 and be arranged in the foot bath cavity 22. When the user uses the foot bath to soak his feet, the foot bath cavity 22 will be filled with water and there will be residual water after soaking his feet. Therefore, the telescopic mechanism 4 needs to be sealed to isolate water vapor. A telescopic flexible sleeve 5 is provided on the periphery of the telescopic mechanism 4. The telescopic flexible sleeve 5 seals the telescopic mechanism 4 to isolate water vapor, thereby playing a sealing and waterproof role. The telescopic flexible sleeve 5 is also made of flexible material so that it can be folded when the foot bath is folded and stretched when it is opened.

[0043] A second cavity 421 is provided inside the second support member 42, a first internal thread 423 is provided inside the upper end of the second support member 42, a second internal thread 424 is provided inside the lower end of the second support member 42, a first external thread 411 is provided on the first support member 41, the first external thread 411 is meshed with the first internal thread 423, and a third external thread 432 is provided on the third support member 43, the third external thread 432 is meshed with the second internal thread 424. When the foot bath is folded, the first support member 41 and the second support member 42 are both located in the second cavity 421. In order to facilitate assembly during production, the first support member 41 and the second support member 42 are threadedly connected to the second support member 42, and the second support member 42 is configured to be composed of two half shells, namely a front support shell and a rear support shell, which enclose the second cavity 421. During assembly, the first support rod is first connected to the first internal thread 423 of the front support shell, and the third support rod is connected to the second internal thread 424, and then the rear support shell is assembled. The rear support shell can be connected to the front support shell by a screw or a buckle structure, so that the production and assembly efficiency can be effectively improved. The first internal thread, the first external thread, the second internal thread and the third external thread are all oblique threads. Through the rotation of the second support member and the meshing relationship of the oblique thread, the second support member and the first support member can slide upward and downward along the height direction of the foot bath. By arranging a threaded structure at the upper end and the lower end of the second support member, the first support member and the third support member can be connected respectively, so that the three interact with each other, so that when the second support member rotates, the second support member can be moved up and down relative to the third support member, and the first support member can be moved up and down relative to the second support member at the same time. The three support members are connected by a simple threaded structure and they can move relative to each other, so as to realize the extension and retraction of the telescopic mechanism. The telescopic mechanism has a simple structure, is easy to manufacture, and has a low manufacturing cost.

[0044] The first support member 41 and the third support member 43 are preferably coaxially arranged, and the axes of the two are on the same straight line. Of course, in some other embodiments, the first support member 41 and the second support member 42 can also be arranged side by side, and the two can be adjacent to each other when located in the second cavity 421. The first support member 41 and the third support member 43 are located in the second cavity 421, which means that most of them are embedded in the second cavity 421, and they do not necessarily have to extend into the second cavity 421.

[0045] like Figure 1 , Figure 3-Figure 5As shown, the second support member 42 and the third support member 43 are both cylindrical structures, the first support member 41 is a rod-shaped structure, and the third support member 43 is provided with a third cavity 431. When the footbath is folded, the third support member 43 is nested in the second cavity 421, and the first support member 41 is embedded in the third cavity 431. The axes of the first support member, the second support member, and the third support member are located on the same straight line. The design of the supports being nested in pairs is conducive to saving space, reducing the diameter of the second support member, and the axes of the three supports are located on the same straight line. The support of the footbath is more stable during the opening process and in the open state, and the inner wall of one of the three supports can be abutted against another support member during the extension and retraction process of the telescopic mechanism, which further reduces shaking and displacement and improves the stability of the telescopic mechanism.

[0046] A limiting structure for reducing the matching gap between the third support member 43 and the first support member 41 is provided on the inner wall thereof, and the limiting structure includes a limiting rib 433 and a limiting groove 412. One of the limiting rib 433 and the limiting groove 412 is provided on the inner wall of the third support member 43, and the other of the limiting rib 433 and the limiting groove 412 is provided on the outer wall of the first support member 41. Figure 1 , Figure 4 and Figure 5 As shown, a limiting groove 412 is provided on the outer wall of the first support member 41, and a limiting rib 433 is provided on the inner wall of the third support member 43. The limiting structure is provided, and the limiting rib and the limiting groove cooperate with each other so that the first support member and the second support member are mutually reinforced and fixed to prevent the two from rotating relative to each other. At the same time, the matching degree between the first support member and the third support member can be improved, the matching gap can be reduced, and the shaking problem occurring during the relative movement between the two can be further reduced, thereby improving stability.

[0047] The foot bath also includes a driving assembly, which includes a motor 6 and a driving gear 7. A tooth structure 422 is provided on the second support member 42. The tooth structure 422 can be a gear / rack installed on the second support member 42, or can be a tooth structure directly formed on the outer surface of the second support member 42. The driving gear 7 is meshed with the tooth structure 422 to drive the second support member 42 to rotate. The driving assembly is connected to the second support member 42, the third support member 43 is connected to the seat body 3, and the first support member 41 is connected to the upper body 1. When the motor 6 is working, the second support member 42 drives the first support member 41 and the driving assembly to move synchronously relative to the third support member 43 in a direction away from the seat body 3, that is, to move upward along the height direction of the foot bath. The second support member is provided with a tooth structure, which is convenient for connecting with the driving gear to realize power transmission, and because the second support member drives the first support member to move upward, and the first support member moves upward relative to the second support member, the telescopic mechanism realizes a double movement stroke in a unit time, shortens the time to open the foot bath, and enables the foot bath to open quickly and stably.

[0048] The second support member 42 is a hollow cylindrical structure with a second cavity 421 formed inside. A tooth structure 422 is provided on the outer surface of the upper end of the second support member 42. A first inner hole is provided inside the upper end of the second support member 42. A first inner thread 423 is provided on the inner wall of the first inner hole. The first inner thread 423 is engaged with the outer thread of the first support member 41, and one end of the first support member 41 can extend from the first inner hole. A second inner thread 424 is provided on the inner wall of the second cavity 421 to engage with the outer thread of the third support member 43, or the lower end of the second cavity 421 is connected to the second inner hole and a second inner thread 424 is provided on the inner wall of the second inner hole. Figure 5 As shown, the second internal thread 424 is directly disposed on the inner wall of the second cavity; Figure 8 As shown, the second cavity is connected to the second inner hole, and the second inner thread is arranged on the inner wall of the second inner hole. By providing the inner threads at the upper and lower ends of the second support respectively, the first support and the third support can be respectively threadedly connected, so that the connection structure of the three is simple, and no additional matching structures such as sliders are required. The design is ingenious, the number of parts is reduced, the cost of the telescopic mechanism is saved, and / or the matching between parts is reduced, which helps to improve the stability of the telescopic mechanism.

[0049] The driving gear 7 includes at least three gear groups, namely, a primary reduction group, a secondary reduction group and a tertiary reduction group. The primary reduction group includes a first gear 71 and a second gear 72 meshing therewith, the first gear 71 is connected to the output shaft of the motor 6, and the diameter of the second gear 72 is larger than the first gear 71; the secondary reduction group includes a third gear 73 and a fourth gear meshing with the third gear 73, the third gear 73 is coaxially arranged with the second gear 72, and the diameter of the fourth gear 74 is larger than the third gear 73; the tertiary reduction group includes a fifth gear 75 and a sixth gear 76, the fifth gear 75 is coaxially arranged with the fourth gear 74, the sixth gear 76 is meshed with the fifth gear 75, the sixth gear 76 is meshed with the tooth structure 422 for transmission, or the seventh gear 77 coaxially arranged with the sixth gear 76 is meshed with the tooth structure 422 for transmission. This embodiment uses at least three-stage multi-stage gear groups to transmit power, with high transmission accuracy and high transmission efficiency, and can provide greater power to the telescopic mechanism; and / or can reduce the strength requirements for each gear, and the reliability of the components is higher and the stability is good.

[0050] The second support member 42 is provided with a housing 8 on the outside, the motor 6 and the driving gear 7 are mounted on the housing, a placement cavity 81 is provided in the housing 8, the second support member 42 is located in the placement cavity 81 and is wrapped by the cavity wall of the placement cavity 81, and when the telescopic mechanism 4 is extended, the first support member 41 and the third support member 43 are exposed outside the housing 8. Specifically, the housing 8 may include a front housing 82 and a rear housing 83 connected to each other, and after the front housing 82 and the rear housing 83 are connected, a housing cavity is formed inside to wrap the motor 6, the driving gear 7 and the second support member 42, and the housing cavity includes a placement cavity 81 for placing the second support member 42. The second support member is wrapped by the placement cavity, and although it rotates during the extension and retraction process, the cavity wall of the placement cavity plays a good limiting role on the second support member, reducing the deviation and shaking of the second support member, and further improving the stability of the entire telescopic mechanism. The housing also facilitates the installation of the motor and the driving gear so as to move synchronously with the second support member.

[0051] The seat body 3 is provided with an upper limit switch and a lower limit switch, both of which are electrically connected to the controller. A trigger is provided on the telescopic mechanism 4 or the housing, and the lower limit switch is triggered when the telescopic mechanism 4 is retracted, and the upper limit switch is triggered when the telescopic mechanism 4 is extended. By setting the upper limit switch and the lower limit switch, the telescopic mechanism is detected when it is extended and lowered, and the motor is stopped in time, which plays a detection and protection role.

[0052] Taking the third support member 43 fixedly connected to the seat body 3 and the first support member 41 connected to the upper body 1 as an example, the specific movement process of the foot bath during use is explained: when in use, the foot bath is opened from a folded state, and the user activates the power button or the lifting button. The motor 6 drives the driving gear 7 to rotate, and the second support member 42 is linked to rotate through the tooth structure 422. The second support member 42 is engaged with the third external thread 432 of the third support member 43 through the second internal thread 424 thereon, so that the second support member 42 can spirally rise along the outer wall of the third support member 43, driving the first support member 41, the shell, and the motor 6 and the driving gear 7 assembled in the shell to move upward together. At the same time, due to the transmission cooperation of the first internal thread 423 of the second support member 42 and the first external thread 411 of the first support member 41, the first support member also spirally rises relative to the second support member, so that the end thereof connected to the upper body 1 extends upward from the second cavity 421. When the second support member 42 rises to the highest position and / or the first support member 41 also rises to the highest position, the telescopic mechanism 4 extends to its position, and the upper limit switch detects a signal and controls the motor 6 to stop working. At this time, the user can add water to the foot bath and start the massage component to perform foot massage. After the user uses the foot bath, the movement of the telescopic mechanism 4 during the folding and storage process is opposite to that during the opening process. During storage, the second support member 42 drives the shell, the motor 6, etc. to descend into the installation cavity 31, the first support member 41 is embedded in the third support member 43, and the third support member 43 is embedded in the second support member 42, so that the upper body 1 descends as close to the bottom wall of the foot bath cavity 22 as possible, reducing the overall height of the foot bath after folding.

[0053] Embodiment 2:

[0054] like Figure 6-Figure 8 As shown, the embodiment of the utility model is basically the same as the first embodiment, the only difference is that the driving gear of the telescopic mechanism is different and the tooth structure is different.

[0055] The driving gear 7 includes a helical gear and one or more transmission gear groups. The input end of the transmission gear group is connected to the output shaft of the motor 6, and the output end is connected to the helical gear. The tooth structure 422 is a bevel gear. The tooth structure 422 is arranged at the lower end of the second support member 42. Of course, it can also be arranged at the upper end of the second support member 42 as in the first embodiment. A buckle 781 is provided on one of the bevel gear and the second support member 42. A buckle groove 425 is provided on the other of the bevel gear and the second support member 42. The buckle 781 is buckled into the buckle groove 425 to connect the bevel gear to the second support member 42. Specifically, it can be a buckle hook fastener, and the buckle 781 is buckled into the buckle groove 425 and fixed by the buckle hook. By setting the buckle structure to install the bevel gear to the second support member, the assembly structure is simple and the production efficiency is high.

[0056] The driving gear of this embodiment adopts another method, which also has the advantages of high transmission accuracy, high transmission efficiency and stable transmission.
