DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0039] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Please refer to Figures 1 to 15 The embodiment of the present application provides a foot bath machine 100, including a barrel body 10 with a first opening 11, a partition 12 is fixedly provided on one side of the barrel body 10 away from the first opening 11, so as to separate the barrel body 10 into a first accommodating chamber 121 and a second accommodating chamber 122, the first accommodating chamber 121 is used to accommodate the foot, the foot bath machine 100 also includes a massage head assembly 20 and a lifting mechanism 30, a second opening 123 is provided on the partition 12, the massage head assembly 20 can extend into the first accommodating chamber 121 through the second opening 123, the lifting mechanism 30 is transmission-connected with the massage head assembly 20, and the lifting mechanism 30 is used to drive the massage head assembly 20 to move toward or away from the first opening 11. The foot bath machine 100 can adaptively adjust the height of the massage head 22, so that the user can obtain the best foot bathing posture, thereby improving the user's experience.

[0042] It should be noted that if Figures 1 to 3As shown, the foot bath machine 100 includes a barrel body 10, wherein the barrel body 10 has a first opening 11, and a partition 12 is fixedly provided on the side of the barrel body 10 away from the first opening 11 to separate the space inside the barrel body 10 into a first accommodating chamber 121 and a second accommodating chamber 122. For example, in this embodiment, the first opening 11 is located at the top of the barrel, and a partition 12 is fixedly provided on the side of the barrel body 10 away from the top of the barrel (or the side of the barrel body 10 close to the bottom of the barrel) to separate the barrel body 10 into a first accommodating chamber 121 for foot hot bathing and a second accommodating chamber 122 for accommodating functional components, so that the partition 12 prevents water in the first accommodating chamber 121 from entering the second accommodating chamber 122, thereby preventing the functional components from being damaged due to accidental water ingress. Optionally, the foot bath machine 100 also includes a cover body (not shown in the figure), which covers the barrel body 10 to close the first opening 11 of the barrel body 10.

[0043] There is no specific limitation on the actual structure of the barrel body 10. For example, the barrel body 10 can be an integral structure in which the enclosure, bottom plate and partition 12 are fixedly connected or integrally formed. Alternatively, the barrel body 10 can also include a base and a barrel body, wherein the barrel body is a cylindrical structure which is circumferentially closed and open at both ends. The partition 12 is fixedly arranged on the top of the base, and the barrel body is installed on the base. The partition 12 located on the top of the base closes the opening located at the bottom of the barrel body (i.e., another opening arranged opposite to the first opening 11) to prevent water in the barrel body (i.e., the first accommodating chamber 121) from entering the base (i.e., the second accommodating chamber 122) through the partition 12. When the barrel body 10 is a split structure in which the base and the barrel body are assembled in combination, it can facilitate the maintenance and replacement of the functional components accommodated in the base (i.e., the second accommodating chamber 122).

[0044] In order to improve the functionality of the foot bath machine 100, Figures 1 to 4 As shown, the foot bath machine 100 provided in the present application also includes a massage head assembly 20, and a second opening 123 is provided on the partition 12. The massage head assembly 20 can extend into the first accommodating cavity 121 through the second opening 123. When taking a hot bath for the foot, the user can extend the foot into the first accommodating cavity 121 through the first opening 11, and fit and contact the part of the massage head assembly 20 extending into the first accommodating cavity 121, so that the massage head assembly 20 can massage the sole of the foot. Since the second opening 123 is provided on the partition 12, in order to ensure the airtightness of the second accommodating cavity 122, those skilled in the art should be able to seal the second opening 123 through a protective cover with waterproof performance without affecting the normal operation of the massage head assembly 20, and no specific restrictions are made here.

[0045] In the prior art, the barrel body of the foot bath machine (equivalent to the barrel body 10 in the present application) has a fixed height, that is, the distance between the barrel top and the barrel bottom is fixed, and the massage head (equivalent to the massage head assembly 20 in the present application) has a fixed height, that is, the distance between the massage head and the barrel top or barrel bottom is fixed. When the user's height or seat height is different, the height of the massage head cannot be adaptively adjusted, resulting in the user being unable to obtain the best foot bathing posture, seriously affecting the user's experience.

[0046] In order to solve the above problems, the foot bath machine 100 provided by the present application is as follows: Figures 2 to 4 As shown, the massage head assembly 22 further includes a lifting mechanism 30, which is connected to the massage head assembly 20 in a transmission manner and is used to drive the massage head assembly 20 to move toward a side close to or away from the first opening 11, thereby correspondingly adjusting the height of the massage head assembly 20. Specifically, when the lifting mechanism 30 drives the massage head assembly 20 to move toward a side close to the first opening 11, the distance between the massage head assembly 20 and the top of the barrel is reduced, which can be suitable for users with shorter stature (especially short legs) or a bench with a higher seat surface, so that the user's feet can keep in contact with the massage head assembly 20 in a more comfortable state, and the user's feet will not be unable to contact the massage head assembly 20; when the lifting mechanism 30 drives the massage head 22 to move toward a side away from the first opening 11, the distance between the massage head assembly 20 and the top of the barrel is increased, which can be suitable for users with taller stature (especially long legs) or a bench with a lower seat surface, so that the user's feet can keep in contact with the massage head assembly 20 in a more comfortable state, and the user's legs will not inevitably curl up excessively.

[0047] Specifically, Figures 2 to 6 As shown, the lifting mechanism 30 includes a lifting drive assembly 31 and a scissor lift assembly 32, the lifting drive assembly 31 is connected to the scissor lift assembly 32 by transmission, the scissor lift assembly 32 is fixedly connected to the massage head assembly 20, and the lifting drive assembly 31 is used to drive the scissor lift assembly 32 to drive the massage head assembly 20 to move. Among them, the lifting drive assembly 31 is used to provide driving force for the scissor lift assembly 32, so that the scissor lift assembly 32 can drive the massage head assembly 20 to move toward or away from the first opening 11. For example, the lifting drive assembly 31 can be set to one, and the scissor lift assembly 32 can be designed according to the number of massage head assemblies 20. For example, in this embodiment, there are two massage head assemblies 20 and two scissor lift assemblies 32, so that the user's left foot and right foot can be massaged at the same time through the two massage head assemblies 20, and the two massage head assemblies 20 can be lifted and lowered at the same time through the two scissor lift assemblies 32.

[0048] For example, Figure 6As shown, in this embodiment, the lifting drive assembly 31 includes a first motor fixing seat 311 fixedly arranged in the second accommodating chamber 122, a first motor 312 fixedly arranged in the first motor fixing seat 311, a first worm 313 fixedly connected to the output shaft of the first motor 312, and a worm wheel 314 rotatably connected to the first worm 313, and the worm wheel 314 is transmission-connected to the scissor lift assembly 32. Among them, the first worm 313 and the worm wheel 314 are arranged to achieve reversal, so that the lifting drive assembly 31 can be reasonably arranged in the second accommodating chamber 122, thereby avoiding excessive increase in the overall volume of the foot bath machine 100. Of course, in other embodiments, if reversal is not required, the lifting drive assembly 31 can only include the first motor fixing seat 311 and the first motor 312, and the output shaft of the first motor 312 is directly transmission-connected to the scissor lift assembly 32.

[0049] For example, Figure 5 and Figure 6 As shown, the scissors-fork lifting assembly 32 includes a scissors-fork frame 321, and the scissors-fork frame 321 includes a plurality of first connecting rods 3211 hinged end to end in sequence and a plurality of second connecting rods 3212 hinged end to end in sequence, the centers of the plurality of first connecting rods 3211 and the centers of the plurality of second connecting rods 3212 are hinged one by one, the first connecting rod 3211 on the side of the scissors-fork frame 321 away from the second opening 123 is rotatably arranged in the second accommodating chamber 122, the second connecting rod 3212 on the side of the scissors-fork frame 321 away from the second opening 123 is transmission-connected to the lifting drive assembly 31, a connecting seat 322 is slidably arranged on the second connecting rod 3212 on the side of the scissors-fork frame 321 close to the second opening 123, the first connecting rod 3211 on the side of the scissors-fork frame 321 close to the second opening 123 is rotatably connected to the connecting seat 322, and the connecting seat 322 is fixedly connected to the massage head assembly 20.

[0050] Among them, the scissor frame 321 includes multiple connecting rods. For the convenience of description and understanding, the first connecting rod 3211 and the second connecting rod 3212 are used for explanation here. The number of the first connecting rod 3211 and the second connecting rod 3212 is equal, which can be an even number or an odd number. The multiple first connecting rods 3211 are hinged end to end in sequence, and the multiple second connecting rods 3212 are hinged end to end in sequence, and the center of the first connecting rod 3211 is hinged corresponding to the center of the second connecting rod 3212. In this way, the free end of the first connecting rod 3211 and the free end of the second connecting rod 3212 located on one side of the scissor frame 321 are close to or away from each other, which will make the free end of the first connecting rod 3211 and the free end of the second connecting rod 3212 located on the other side of the scissor frame 321 synchronously approach or move away from each other. At the same time, the height of the scissor frame 321 can also be raised or lowered, and then the massage head assembly 20 is driven to be raised or lowered synchronously through the connecting seat 322.

[0051] For example, Figures 4 to 6 As shown, the lifting mechanism 30 also includes two fixed transmission seats 33, a screw rod 34 is rotatably arranged between the two transmission seats 33, a slider 35 is sleeved on the screw rod 34, a worm gear 314 is fixedly connected to the screw rod 34, and the slider 35 is rotatably connected to the second connecting rod 3212 on the side of the scissor frame 321 away from the second opening 123, and the worm gear 314 drives the screw rod 34 to rotate relative to the transmission seat 33, so as to drive the slider 35 to move relative to the screw rod 34. Since the screw rod 34 will not be axially displaced during the rotation process relative to the transmission seat 33, the slider 35 sleeved on the screw rod 34 can be axially displaced, thereby changing the size of the spacing (or angle) between the two connecting rods of the scissor lift assembly 32.

[0052] The transmission seat 33 may be a standard bearing member, or the transmission seat 33 may further include a transmission member 331 and a transmission sleeve 332, wherein the transmission sleeve 332 is fixedly disposed in the second accommodating chamber 122, the transmission member 331 is rotatably disposed in the transmission sleeve 332, and the lifting drive assembly 31, the transmission member 331 and the screw rod 34 are fixedly connected in sequence, so that the driving force of the lifting drive assembly 31 can be transmitted to the screw rod 34 through the transmission member 331, thereby driving the screw rod 34 to rotate relative to the transmission seat 33. When the lifting drive assembly 31 includes a first worm 313 and a worm wheel 314, the worm wheel 314, the transmission member 331 and the screw rod 34 may be fixedly connected in sequence through a transmission shaft, and an elastic member may be sleeved on the transmission shaft, and the two ends of the elastic member are respectively against the worm wheel 314 and the transmission member 331, so that the transmission of the driving force is more stable. In addition, in order to protect the above-mentioned parts, a housing 36 may be provided to accommodate the above-mentioned parts in the housing 36.

[0053] In order to make the massage head assembly 20 work properly, Figures 2 to 8 As shown, in this embodiment, a massage head driving assembly 40 is further disposed in the second accommodating chamber 122, so that the massage head driving assembly 40 provides driving force for the massage head assembly 20, thereby massaging the user's foot through the massage head assembly 20. On this basis, as Figure 3 , Figures 7 to 10 As shown, a retractable transmission sleeve assembly 50 is also disposed in the second accommodating chamber 122. The massage head assembly 20 includes a mounting seat 21 fixedly connected to the lifting mechanism 30 and a massage head 22 rotatably disposed on the mounting seat 21 (such as Fig. 9 and Fig.10 As shown, in order to improve the reliability of the direct connection between the mounting base 21 and the lifting mechanism 30, a reinforcing plate 23 can be added to the bottom of the mounting base 21, the massage head driving assembly 40 is connected to the retractable transmission sleeve assembly 50, and the retractable transmission sleeve assembly 50 is fixedly connected to the massage head 22, for example, Fig.13As shown, the retractable transmission sleeve assembly 50 is fixedly connected with the massage head 22, and the movement of the mounting seat 21 relative to the partition 12 can drive the retractable transmission sleeve assembly 50 to retract, and the massage head driving assembly 40 drives the retractable transmission sleeve assembly 50 to rotate to drive the massage head 22 to rotate relative to the mounting seat 21. As the massage head assembly 20 is raised or lowered, the retractable transmission sleeve 332 can be extended or shortened synchronously, and at the same time, the retractable transmission sleeve 332 can also transmit the driving force of the massage head driving assembly 40 to the massage head 22, thereby ensuring that the transmission of the driving force between the massage head driving assembly 40 and the massage head assembly 20 is always effective, and will not fail due to the height change of the massage head assembly 20.

[0054] For example, Figure 7 and Figure 8 As shown, in this embodiment, the massage head drive assembly 40 includes a second motor fixing seat 41 fixedly arranged in the second accommodating chamber 122, a second motor 42 fixedly arranged in the second motor fixing seat 41, a second worm 43 fixedly connected to the output shaft of the second motor 42, and a reduction gear set 44 rotatably connected to the second worm 43, and the reduction gear set 44 is transmission-connected to the telescopic transmission sleeve set 50. Among them, the second worm 43 and the reduction gear set 44 are, on the one hand, for realizing the reversing arrangement, so that the massage head drive assembly 40 can be reasonably arranged in the second accommodating chamber 122, thereby avoiding excessive increase in the overall volume of the foot bath machine 100, and on the other hand, the speed of the second motor 42 transmitted to the telescopic transmission sleeve set 50 can be reduced by the reduction gear set 44, thereby avoiding the telescopic transmission sleeve 332 from being easily damaged due to the high speed of the second motor 42. In addition, the specific number of the reduction gear set 44 in the figure is only for illustration, and is not used to limit the actual number of the reduction gear set 44.

[0055] For example, Fig.11 and Fig.12As shown, in this embodiment, the telescopic transmission sleeve group 50 includes at least two sleeves 51, and the inner wall and outer wall of each sleeve 51 are respectively provided with an inner guide groove 511 and an outer guide bar 512, and the outer guide bar 512 of the sleeve 51 away from the second opening 123 is slidably arranged in the inner guide groove 511 of the sleeve 51 close to the second opening 123, so that the two adjacent sleeves 51 are nested and limited in the circumferential direction, so that the telescopic transmission sleeve 332 can realize the rotation transmission of the driving force, and at the same time, the telescopic transmission sleeve 332 can also be guided by the inner guide groove 511 and the outer guide bar 512; the two opposite sides of each sleeve 51 A buckle 513 and a groove 514 are respectively provided at the ends. The groove 514 of the sleeve 51 away from the second opening 123 is snapped with the buckle 513 of the sleeve 51 close to the second opening 123, so that the two adjacent sleeves 51 are axially snap-connected and limited.
