[0001] This application belongs to the technical field of foot cleaning equipment, specifically relating to a foot washing machine. Background Technology

[0002] A foot bath machine is a foot cleaning device used to wash feet. It features vertical brush columns that rotate to clean the sides of the foot. However, existing foot bath machines only allow the vertical brush columns to rotate around their own axis and cannot move during the cleaning process. If the user's feet remain stationary, only a limited area of ​​the sides of the foot can be cleaned, resulting in ineffective cleaning. Furthermore, the back of the heel is also difficult to clean, negatively impacting the user experience. Summary of the Invention

[0003] The purpose of this application is to provide a foot washing machine that at least solves the problem of poor cleaning effect on the back of the heel, which affects the user experience.

[0004] To achieve the above objectives, this application provides a foot washing machine, comprising:

[0005] Foot basin; A cleaning mechanism is provided inside the foot basin. The cleaning mechanism includes two cleaning components. The two cleaning components can be close to each other or far apart. When the two cleaning components are close to each other, they clean the back of the heel together. When the two cleaning components are far apart, they open on both sides of the foot to clean the two sides of the foot.

[0006] Optionally, the foot washing machine further includes: A movable support, wherein the movable support is disposed inside the foot basin; A support drive assembly is used to drive the movable support to move along a first direction between a first position and a second position. The cleaning mechanism is connected to the movable support. When the movable support is in the first position, the two cleaning components are close to each other. When the movable support moves from the first position to the second position, it drives the two cleaning components to move and the two cleaning components gradually move away from each other.

[0007] Optionally, the cleaning component is hinged to the movable support, and when the movable support moves from the first position to the second position, the cleaning component swings relative to the movable support at a certain angle so that the two cleaning components move away from each other; The foot washing machine also includes a closing mechanism, which is disposed between the movable support and the washing components, and is used to drive the two washing components to move closer to each other.

[0008] Optionally, the closing mechanism includes a first compression spring disposed between the cleaning component and the movable bracket.

[0009] Optionally, the foot bath also includes a heel base assembly disposed on the bottom surface of the foot basin and used to support at least the bottom surface of the heel. When the movable support moves from the first position to the second position, the two cleaning components are used to place on the heel base assembly and spread out so that the two cleaning components are far apart from each other and fit against the sides of the foot.

[0010] Optionally, the foot washing machine also includes a controller, and the heel assembly includes a sensing and detection unit, which includes a pressure trigger switch or a pressure sensor.

[0011] Optionally, the foot washing machine also includes a heel drive assembly, which can drive the heel drive assembly to rotate to clean the bottom of the user's heel. When the sensing detection unit detects that the user's foot is placed on the heel drive assembly, the controller also synchronously controls the heel drive assembly to drive the heel drive assembly to rotate, and the controller delays the start of operation of the support drive assembly.

[0012] Optionally, the foot washing machine further includes a maintaining open mechanism, which pushes and / or pulls the washing components outward and / or pulls them apart during the movement of the movable support from the first position to the second position, so that the two washing components remain in a state of being far apart from each other.

[0013] Optionally, the maintaining opening mechanism includes a limiting post disposed on the bottom surface of the foot basin. When the cleaning component moves from the first position to the second position and passes the limiting post, the limiting post is located inside the cleaning component to push the cleaning component outward, so that the two cleaning components remain in the open state.

When the movable bracket moves from the first position to the second position, and the cleaning component passes the limiting post, the limiting post drives the cleaning component to open outward, so that the limiting snap ring is locked on the movement guide rod. When the movable bracket moves from the second position to the first position, the cleaning component remains in the open state under the action of the limiting snap ring. When it continues to move to the guide rib, under the drive of the guide rib, the two cleaning components move in a direction that moves closer to each other, and under the elastic push of the first compression spring, the limiting snap ring disengages from the movement guide rod.

The cleaning mechanism includes two cleaning components. When the two cleaning components are close to each other, they jointly clean the back of the heel; when they are far apart, they clean the sides of the foot separately. The ability of the two cleaning components to move closer or further apart solves the problem of ineffective cleaning of the back of the heel, which affects the user experience. The two cleaning components can clean the back of the heel when close to each other and also clean the sides of the foot when open, simultaneously cleaning multiple areas of the foot. This avoids the complex structure of multiple cleaning components, effectively simplifying the foot bath machine's structure and reducing its cost.

[0044] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present application, and should not be construed as limiting the present application.

[0045] See 1 to Figure 4 and Figure 12 As shown, in this embodiment, the foot washing machine includes a foot basin 100 and a washing mechanism, which includes two washing components 300. The two washing components 300 can move closer to each other or further apart. When the two washing components 300 are close to each other, they jointly wash the back of the heel. When the two washing components 300 are far apart, they open on both sides of the foot to wash the two sides of the foot.

[0046] The existing foot washing machines have vertical brush columns that can only rotate around their own axis and cannot move during the washing process, making it difficult to clean the back of the user's heels and affecting the user experience.

[0047] In this embodiment, the foot washing machine includes a foot basin 100 and a washing mechanism. The washing mechanism includes two washing components 300. When the two washing components 300 are close to each other, they jointly wash the back of the heel; when the two washing components 300 are far apart, they wash the sides of the foot separately. The ability of the two washing components 300 to move closer or further apart solves the problem of poor cleaning effect on the back of the heel and also has the function of cleaning the sides of the foot. The two heel base components 500 simultaneously have the function of cleaning multiple areas of the back of the heel and the sides of the foot, avoiding the complex structure of setting multiple heel base components 500, effectively simplifying the structure of the foot washing machine and reducing the cost of the foot washing machine.

[0048] In some embodiments, the foot bath further includes a movable support 200 and a support drive assembly 700. The movable support 200 is disposed within the foot basin 100, and the support drive assembly 700 drives the movable support 200 to move along a first direction between a first position and a second position. The cleaning mechanism is connected to the movable support 200. When the movable support 200 is in the first position, the two cleaning components 300 move closer to each other; when the movable support 200 moves from the first position to the second position, the movable support 200 drives the two cleaning components 300 to move, and the two cleaning components 300 gradually move away from each other.

[0049] The first direction is usually the front-back direction of the foot basin 100. When the foot is placed in the foot basin 100, it is usually placed along the first direction, with the toes at the front end of the first direction and the heel at the rear end of the first direction. When the movable support 200 is in the first position, it is usually located near the rear end of the foot basin 100, and the heel assembly 500 contacts and cleans the heel. When the movable support 200 moves from the first position to the second position, it moves to the front end near the foot basin 100, at which time the front end of the side of the foot (the toes) is cleaned.

[0050] In the initial state, the movable support 200 is in the first position, and the two cleaning components 300 are close to each other. When the user's foot is placed in the foot basin 100, the cleaning components 300 can clean the back of the user's heel. After the back of the heel is cleaned, the movable support 200 moves the cleaning components 300 to the second position along the first direction. During this process, the two cleaning components 300 gradually open along the side of the foot and move away from each other to clean the side of the user's foot. By setting the two heel-side components 500 of the cleaning mechanism on the movable support 200, and moving the two heel-side components 500 through the movable support 200, the two heel-side components 500 can simultaneously clean the front and rear ends of the side of the foot, that is, the entire side of the foot from the heel to the toe, for a comprehensive, thorough, and clean cleaning.

[0051] It should be noted that the support drive assembly 700 can be any structure capable of driving the movable support 200, such as a lead screw and slider electric assembly, a pulley electric assembly, a telescopic rod drive assembly, a cross rod drive assembly, a piston push rod assembly, etc.

[0052] In some embodiments, the washing components 300 are hinged to the movable support 200. The two washing components 300 may be spaced apart along a second direction, typically the width / left-right direction of the foot bath 100, substantially perpendicular to the front-back of the foot bath 100. As the movable support 200 moves from a first position to a second position, the washing components 300 swing relative to the movable support 200 at a certain angle to move the two washing components 300 away from each other. The foot bath also includes a closing mechanism disposed between the movable support 200 and the washing components 300, for driving the two washing components 300 closer together.

[0053] In the initial state, the movable support 200 is in the first position, and the two cleaning components 300 are in an inwardly closed state. When the user's foot is placed in the foot basin 100, the cleaning components 300 can clean the back of the user's heel. After the back of the heel is cleaned, the movable support 200 moves the cleaning components 300 along the first direction to the second position. During this process, the two cleaning components 300 gradually move away from each other, cleaning the side of the user's foot. For example, when the heel assembly 500 moves in the second direction, it moves along the outer contour of the user's foot. Under the force of the foot, the two cleaning components 300 open outward and are located on the left and right sides of the foot respectively. However, the closing mechanism keeps the cleaning components 300 close to the side of the user's foot, so that the side of the user's foot can be cleaned during the movement of the cleaning components 300. After cleaning, the movable support 200 moves the cleaning components 300 along the first direction to the first position. After passing the user's foot, the cleaning components 300 close inward under the action of the closing mechanism, returning to the initial state.

[0054] The closing mechanism drives the cleaning component 300 to close inward to adapt to the shape of the user's foot. The user's foot can be cleaned without moving, and when cleaning the side of the foot during movement, the closing mechanism can make the heel component 500 fit against the side of the foot, which can more effectively clean the side of the foot. This solves the problem of poor cleaning effect on the side of the foot and the back of the heel, which affects the user's experience.

[0055] It should be noted that the closing mechanism can be any spring, thermoplastic elastomer, rubber, or highly elastic sponge with a pushing force. The closing mechanism can also be other combined structural components, such as pneumatic structures like airbags, motor structures like electric push rods, or adsorption structures like magnets or electromagnetic coils. For example, the closing mechanism can use a torsion spring, which can be located at the hinge axis between the cleaning component 300 and the movable support 200. The closing mechanism can also use a first magnet, with a pair of first magnets located between the cleaning component 300 and the movable support 200. One first magnet is located on the outside of the cleaning component 300, and the other is located on the movable support 200. The two first magnets, with their like poles repelling each other, drive the two cleaning components 300 to close inwards.

[0056] In some embodiments, the closing mechanism preferably includes a first compression spring 400, with the cleaning member 300 extending partially to the outside of the cleaning member 300, and the first compression spring 400 disposed between the cleaning member 300 and the movable bracket 200. One or more first compression springs 400 may be provided on the outside of each cleaning member 300 to close the two cleaning members 300 inwards. In this embodiment, two first compression springs 400 are provided on the outside of each cleaning member 300.

[0057] The first compression spring 400 can drive the two cleaning components 300 to close inward, and when the moving bracket 200 drives the cleaning components 300 to move forward in the first direction, the first compression spring 400 can make the cleaning components 300 fit tightly against the user's foot side. The two heel-plant components 500 are driven to move closer to each other by a compression spring with elastic force, and can automatically return to their original position after being compressed. The structure is simple and the effect is good.

[0058] In some embodiments, the foot bath also includes a heel base assembly 500, which is disposed on the bottom surface of the foot basin 100 and is used to support at least the bottom surface of the heel. When the movable support 200 moves from the first position to the second position, the two heel base assemblies 500 are used to place the foot on the heel base assembly 500 so that the two washing components 300 are far apart from each other and fit against the sides of the foot.

[0059] The heel base component 500 can serve only to support the bottom of the heel, or it can be used solely to place the heel. Alternatively, the heel base component 500 can both support and simultaneously clean the bottom of the heel. When the heel base component 500 has a cleaning function, the foot bath machine needs to be equipped with a heel drive component to drive the rotation of the heel base component 500 to clean / scrub the bottom of the heel. The heel base component 500 can be marked with the user's foot placement position, making it easy to place the foot into the foot basin 100. The back of the heel can then directly contact the two heel base components 500, and the foot bath machine can clean the back of the heel immediately after starting, without requiring the user to adjust the foot position.

[0060] In some embodiments, the foot bath machine further includes a holding open mechanism that pushes and / or pulls the cleaning components 300 outwards during the movement of the movable support 200 from the first position to the second position, so that the two cleaning components 300 remain in a state of being far apart from each other.

[0061] As the movable support 200 moves from the first position to the second position, the two cleaning components 300 close inward under the action of the closing mechanism to adapt to the shape of the user's foot. When the cleaning components 300 move close to the second position, the maintaining opening mechanism pushes and / or pulls the cleaning components 300 outward to keep the two cleaning components 300 in a state of separation from each other. This ensures that the heel assembly 500 no longer contacts the foot after cleaning, facilitating subsequent actions on the foot by the foot washing machine, such as rinsing the foot with clean water.

[0062] The maintaining opening mechanism can be a structural component such as an inwardly pushing limiting post 110, or an outwardly pulling component such as a tension spring. In some embodiments, the maintaining opening mechanism preferably includes a limiting post 110, which is disposed on the bottom surface of the foot basin 100. When the washing member 300 moves from the first position to the second position and passes the limiting post 110, the limiting post 110 is located inside the washing member 300, pushing the washing member 300 to open outward. That is, in the second direction, the limiting post 110 is located on the side of the washing member 300 away from the closing mechanism.

[0063] Specifically, when the cleaning component 300 moves from the first position to the second position and passes the limiting post 110, the inward-facing side of the front end of the heel assembly 500 has a guide slope, or the rear end of the heel assembly 500 has an inward-protruding structure. This allows the limiting post 110 to have a gap with the front end of the heel assembly 500 and be located inside the heel assembly 500. As the heel assembly 500 continues to move in the second direction, it can push the cleaning component 300 to open outward. The cooperation between the limiting post 110 and the inner side of the heel assembly 500 has the advantages of simple structure and ingenious design.

[0064] In some embodiments, the movable support 200 includes a support body 210 and a motion guide rod 220. The support body 210 includes side supports 211 and a cross link 212, with the two side supports 211 disposed on both sides of the cross link 212 along a second direction. In a first direction, the washing member 300 is disposed on the side of the side support 211 away from the cross link 212, and the motion guide rod 220 extends along the first direction. The side supports 211 pass through the motion guide rod 220, and when the movable support 200 moves between a first position and a second position, the side supports 211 slide on the motion guide rod 220. The motion guide rod 220 may be disposed on the side wall of the foot basin 100, or may be disposed on the bottom surface of the foot basin 100 through a support structure. The support body 210 contacts or is spaced from the bottom surface of the foot basin 100. The support body 210 may also include a spring support 213. In the first direction, the spring support 213 is disposed on the side support 211 and located on the side away from the cross link 212. The spring support 213 is spaced apart from the side support 211. One end of the first compression spring 400 is mounted on the spring support 213.

[0065] The guide rod guides the movement of the support body 210. The support body 210 moves linearly along the movement guide rod 220, which can improve the movement stability of the support body 210. At the same time, the movement guide rod 220 can create a gap between the support body 210 and the bottom surface of the foot basin 100, reducing the resistance during the movement of the support body 210.

[0066] In some embodiments, the maintaining opening mechanism further includes a limiting spring 360 disposed on the cleaning member 300. When the cleaning member 300 passes the limiting post 110 during movement, the limiting post 110 drives the cleaning member 300 to open outward, causing the limiting spring 360 to engage with the movement guide rod 220.

[0067] The limiting spring 360 is engaged with the motion guide rod 220, which allows the two cleaning components 300 to remain open when the movable bracket 200 moves from the second position to the first position. This prevents the cleaning components 300 from contacting the user's feet or allows them to easily avoid other structural components in the middle foot placement area, such as structures with support feet, like the heel assembly 500 described below.

[0068] In some embodiments, the foot basin 100 is further provided with guide ribs 120, and the limiting post 110 and the guide rib 120 are spaced apart along a first direction. The limiting post 110 and the guide rib 120 are each provided in a one-to-one correspondence with the cleaning component 300. The cleaning mechanism also includes a swing bracket 310, and a limiting spring 360 is provided on the outside of the swing bracket 310.

[0069] When the guide rib 120 guides the two heel base components 500 to the first position, they reset, and the two cleaning components 300 return to the closed state for the next cleaning cycle. The guide rib 120 is directly attached to the bottom of the foot basin 100 and can be integrally molded with the foot basin 100, eliminating the need for additional guiding components. This simplifies manufacturing and helps save on manufacturing processes and costs.

[0070] In some embodiments, the foot bath machine further includes a heel base assembly 500 and a heel base drive assembly. The heel base assembly 500 is disposed on the bottom surface of the foot basin 100 to support the bottom surface of the user's heel. The heel base drive assembly can drive the heel base assembly 500 to rotate to clean the bottom surface of the user's heel. That is, the heel base assembly 500 has both the function of supporting the foot and the function of cleaning the bottom of the heel. The heel base assembly 500 is disposed on the side near the guide rib 120 and between the two guide ribs 120 in the direction of movement perpendicular to the movable support 200. That is, in the first direction, the heel base assembly 500 is disposed on the side of the guide rib 120 near the limiting post 110, and in the second direction, the heel base assembly 500 is disposed between the two guide ribs 120.

[0071] The bottom assembly 500 is located on the side of the guide rib 120 near the limiting post 110. A first compression spring 400 is provided between the movable bracket 200 and the cleaning component 300. The first compression spring 400 is used to drive the two cleaning components 300 to move closer to each other. When the movable support 200 moves from the first position to the second position, and the cleaning component 300 passes the limiting post 110, the limiting post 110 drives the cleaning component 300 to open outward, so that the limiting spring 360 is locked on the movement guide rod 220. When the movable support 200 moves from the second position to the first position, the cleaning component 300 remains in the open state under the action of the limiting spring 360, so that the heel-bottom assembly 500 can pass over the heel-bottom assembly 500 and continue to move backward. When it moves to the guide rib 120, under the guidance of the guide rib 120, the two cleaning components 300 move towards each other, and under the push of the elastic force of the first compression spring 400, the limiting spring 360 disengages from the movement guide rod 220, and the two cleaning components 300 close inward and return to the initial state. The next time the user's foot is placed on the heel-bottom assembly 500, it can clean the back of the user's heel.

[0072] In some embodiments, see Figure 8 As shown, the foot bath also includes a controller. The heel assembly 500 includes a sensing unit, which may include a pressure trigger switch or a pressure sensor. When the sensing unit detects that the user's foot is placed on the heel assembly 500, the controller controls the cleaning component 300 to clean the back of the heel. By incorporating a foot-detecting unit, the foot bath automatically starts without the user needing to bend over to press the start button, enhancing the product's intelligence and making it more convenient for users.

[0073] Furthermore, if the foot bath machine has a heel-mounted drive assembly, when the sensing unit detects that the user's foot is placed on the heel-mounted assembly 500, the controller also simultaneously controls the heel-mounted drive assembly to operate, driving the heel-mounted assembly 500 to rotate and clean the bottom of the heel, thus achieving simultaneous and automatic cleaning of the back and bottom of the heel. The heel-mounted drive assembly may include a motor and a gear set.

[0074] The heel assembly 500 also includes a scrubbing head 510, which is rotatably mounted on the bottom surface of the foot basin 100. The axis of rotation of the scrubbing head 510 is arranged along a third direction, and a sensing unit is located below the scrubbing head 510. The side of the scrubbing head 510 away from the bottom surface of the foot basin 100 is recessed inward to conform to the shape of the user's heel. The side of the scrubbing head 510 away from the bottom surface of the foot basin 100 has multiple raised structures to enhance the scrubbing effect.

[0075] When the sensing unit detects that the user's foot is placed on the heel-sole component 500, the controller controls the heel-sole component 500 to begin cleaning the heel. At this time, the controller delays the start of the support drive component 700, meaning that the back of the heel is cleaned for a preset time before the controller starts the support drive component 700, and the moving support 200 begins to move in the second direction. The delayed start of the support drive component 700 allows sufficient time for cleaning the back of the heel; only after the heel is cleaned does the movement begin to clean the sides of the foot.

[0076] In some embodiments, the foot bath machine further includes two positioning detection mechanisms, which are disposed on opposite sides of the foot basin 100 in a first direction. A controller is connected to the positioning detection mechanisms and the support drive assembly 700. The controller controls the support drive assembly 700 to operate, causing the movable support 200 to move from a first position to a second position. One positioning detection mechanism is triggered, and the controller stops the support drive assembly 700. Conversely, when the controller controls the support drive assembly 700 to move the movable support 200 from the second position to the first position, the other positioning detection mechanism is triggered, and the controller stops the support drive assembly 700.

[0077] When the movable support 200 moves to the second position, a positioning detection mechanism is triggered. At this time, the swing support 310 is in the state of maximum opening. After the foot washing machine completes the subsequent treatment of the feet, such as rinsing the feet or rinsing and drying the feet, the controller controls the movable support 200 to move in the opposite direction through the support drive assembly 700. After the guide rib 120 drives the cleaning component 300 to close inward, another positioning detection mechanism is triggered, and the controller controls the support drive assembly 700 to stop.

[0078] The positioning detection mechanism may include a Hall element 101 or a laser emitter, etc. If the positioning detection mechanism uses a Hall element 101, which can be mounted on the side wall of the foot basin 100, a second magnet can be mounted on the spring bracket 213 to cooperate with the Hall element 101 for positioning detection. Alternatively, if the positioning detection mechanism uses a laser emitter, which can be mounted on the side wall of the foot basin 100, the spring bracket 213 and the side bracket 211 can be made of materials with different reflectivities, or the spring bracket 213 can be equipped with a reflective sheet or reflective film to cooperate with the laser emitter for positioning detection. Figure 8 As shown, the Hall elements 101 of the two positioning detection mechanisms are respectively spaced apart at the front and rear of the side wall of the foot basin 100 along the first direction. By controlling the support drive assembly 700 through the positioning detection mechanism, the stroke of the moving support 200 can be precisely controlled, which can prevent the moving support 200 from hitting the front and rear side walls of the foot basin 100.

[0079] In some embodiments, the support body 210 includes a horizontal connecting rod 212 and two side supports 211, which are disposed on both sides of the horizontal connecting rod 212. The cleaning component 300 is connected to the side supports 211. The foot washing machine also includes a foot cleaning assembly 600 for cleaning the soles of the feet. The foot cleaning assembly 600 may include a first motor 610, a first transmission gear set 620, and at least one transverse cleaning brush 630. The transverse cleaning brush 630 may be disposed between the two side supports 211. The first motor 610 is disposed on the horizontal connecting rod 212. The first transmission gear set 620 is drively connected to the first motor 610 and the transverse cleaning brush 630. The structure of the first transmission gear set 620 may be the same as the structure of the third transmission gear set 340 disclosed above, and the structure of the transverse cleaning brush 630 may be the same as the structure of the vertical cleaning brush 320 disclosed above, which will not be described again here. In addition, the foot cleaning assembly 600 may also include a pressure-bearing link 640, which is disposed on the side of the transverse cleaning brush 630 away from the transverse link 212.

[0080] The foot cleaning component 600 is used to clean the user's soles, excluding the heel, achieving a complete cleaning of the entire sole. The pressure-bearing connecting rod 640 supports the user's forefoot, preventing the foot cleaning component 600 from being subjected to excessive weight and thus avoiding difficulty in rotation.

[0081] In some embodiments, see Figure 9 As shown, the bracket drive assembly 700 includes a second motor 710, a second transmission gear set 720, a lead screw 730, and a nut 740. The nut 740 is disposed inside the cross link 212, and the lead screw 730 is disposed inside the nut 740. The second motor 710 and the second transmission gear set 720 are disposed outside the foot basin 100. The lead screw 730 passes through the side wall of the foot basin 100 and is connected to the second motor 710. The second transmission gear set 720 is connected to the second motor 710 and the lead screw 730 in a transmission connection.

[0082] The support drive assembly 700 includes a lead screw 730 and a nut 740, which enable the movable support 200 to move smoothly with a large stroke.

[0083] In some implementations, combined with Figure 5 As shown, the cleaning component 300 includes a vertical cleaning brush 320, and the cleaning mechanism also includes a swing bracket 310, a third motor 330, and a third transmission gear set 340. The vertical cleaning brush 320 and the third motor 330 are mounted on the swing bracket 310, and the third transmission gear set 340 is connected to the third motor 330 and the vertical cleaning brush 320. The length of the vertical cleaning brush 320 extends along the height direction of the foot basin 100, and the upper and lower ends of the vertical cleaning brush 320 are respectively provided with rotating shafts 322. The vertical cleaning brush 320 is connected to the swing bracket 310 through the rotating shafts 322 at the upper and lower ends.

[0084] The third motor 330 and the third transmission gear set 340 are both mounted on the swing bracket 310, which allows the swing bracket 310 to directly control the rotation of the cleaning brush, reducing intermediate transmission structures and making transmission more efficient. Furthermore, the swing bracket 310 remains unaffected during swinging, allowing the vertical cleaning brush 320 to continuously rotate and clean the feet. The cleaning brush extends along the height of the foot basin 100, facilitating the cleaning of the entire upper and lower areas behind the heel.

[0085] The swing bracket 310 has two lugs 311 on the side away from the movable bracket 200, spaced apart in a third direction. The vertical cleaning brush 320 is positioned between the two lugs 311. The rotation shaft 322 of the vertical cleaning brush 320 extends in a third direction and is inserted into the mounting hole of the lug 311. The third direction is the height direction of the foot basin 100. The third motor 330 is mounted on the swing bracket 310, and the third transmission gear set 340 is connected to the third motor 330 and the vertical cleaning brush 320.

[0086] In some other embodiments, the cleaning mechanism may only have a cleaning component 300 without a motor and gear set. The cleaning component 300 may also only have a vertical cleaning brush 320 or only have a vertical cleaning brush 320 and a swing bracket 310. When the vertical cleaning brush 320 contacts the foot, it rotates by the pushing force of the foot.

[0087] Both the inner and outer sides of the swing bracket 310 are arc-shaped. When the two swing brackets 310 are closed inward, the inner contours of the two swing brackets 310 and the two vertical cleaning brushes 320 fit against the rear contour of the heel. The third motor 330 is located outside the swing bracket 310 and does not affect the fit between the inner contours of the swing bracket 310 and the rear contour of the heel. A spring positioning post 312 or a spring positioning hole 313 can be provided on the outer wall of the swing bracket 310. One end of the first compression spring 400 is sleeved in the spring positioning post 312 or provided in the spring positioning hole 313.

[0088] The third transmission gear set 340 may include a motor gear 341, a transmission gear 342, and a drive gear 343. The motor gear 341 is mounted on the output shaft of the third motor 330, the drive gear 343 is mounted at one end of the vertical cleaning brush 320, and the transmission gear 342 is positioned between the motor gear 341 and the drive gear 343, meshing with both the motor gear 341 and the drive gear 343. Through the multi-stage gear transmission of the third transmission gear set 340, the output torque or the rotational speed of the vertical cleaning brush 320 can be increased. The cleaning mechanism may also include a gear cover 350, which is located on the side of the third transmission gear set 340 away from the third motor 330.

[0089] The axis of the vertical cleaning brush 320 is in the third direction. The third motor 330 drives the vertical cleaning brush 320 to rotate. The inner contours of the swing bracket 310 and the two vertical cleaning brushes 320 fit with the contours of the back of the heel, which can achieve efficient cleaning of the back of the heel.

[0090] See Figure 6 and Figure 7 As shown, the vertical cleaning brush 320 includes a brush roller 321, a rotating shaft 322, a limiting pin 323, and a second compression spring 324. Both ends of the brush roller 321 have shaft holes, and the rotating shaft 322 is partially inserted into the shaft holes of the brush roller 321. The second compression spring 324 is disposed between the bottom surface of the shaft hole of the brush roller 321 and the rotating shaft 322. The side wall of the brush roller 321 has an elongated groove 3211, and the limiting pin 323 passes through the groove 3211 and the rotating shaft 322. The axial length of the groove 3211 allows the rotating shaft 322 to be partially or completely retracted into the brush roller 321. Of course, if there is a large gap between the brush roller 321 and the lug 311 after assembly, the rotating shaft 322 does not need to be completely retracted into the brush roller 321. The brush roller 321 is equipped with bristles, which are evenly spaced in the axial direction. Adjacent bristles in the axial direction are staggered in the circumferential direction. The staggering method is to stagger along one direction to ensure that the bristles are in contact with the foot at every time point without interruption, resulting in a better brushing experience.

[0091] The second compression spring 324 is located between the bottom surface of the shaft hole of the brush roller 321 and the rotating shaft 322. The rotating shaft 322 can retract into the brush roller 321. When installing the vertical cleaning brush 320, by squeezing the rotating shaft 322, the second compression spring 324 is compressed, and the rotating shaft 322 retracts inward into the brush roller 321, making it easy for the vertical cleaning brush 320 to be inserted into the mounting hole of the support lug 311. When disassembling, the vertical cleaning brush 320 can be easily removed from the swing bracket 310 by pulling the limit pin 323 downward, causing the rotating shaft 322 to retract into the brush roller 321.

[0092] In some embodiments, the foot bath machine further includes a foot washing component 1000, which is at least partially disposed within the foot basin 100 and spaced from the bottom surface of the foot basin 100. The foot washing component 1000 is used to wash the user's feet.

[0093] The cleaning mechanism is used to clean the back and sides of the heel, the heel bottom component 500 is used to clean the bottom of the heel, the foot bottom cleaning component 600 is used to clean the area of ​​the user's foot other than the bottom of the heel, and the foot top cleaning component 1000 is used to clean the top of the foot. The foot washing machine can achieve all-round cleaning of the user's feet.

[0094] In some embodiments, the foot washing machine also includes a spray assembly 800. Before or while the cleaning component 300 is cleaning the back of the heel, the controller controls the spray assembly 800 to spray cleaning agent. After the movable bracket 200 moves to the second position, the swing bracket 310 opens to its maximum extent, the heel base component 500 no longer contacts the foot, and the controller controls the spray assembly 800 to spray clean water, making it more convenient to rinse the feet.

[0095] Before or while the cleaning component 300 is cleaning the back of the heel, the spray component 800 sprays cleaning agent onto the user's feet for better cleaning results. After the support drive component 700 stops, the spray component 800 sprays clean water to rinse away the cleaning brush and cleaning agent and dirt from the user's feet.

[0096] In some embodiments, see Figure 10 and Figure 11 As shown, the spray assembly 800 includes a first liquid tank 810, a spray pipe 820, and a second liquid tank 830. The first liquid tank 810 stores detergent, and the second liquid tank 830 stores clean water. The first liquid tank 810 and the second liquid tank 830 are respectively located on both sides of the foot basin 100 in a second direction. The spray pipe 820 is connected to the first liquid tank 810 and the second liquid tank 830 via a liquid pump. The outlet of the spray pipe 820 can be located at multiple positions on the side wall of the foot basin 100. The foot bath may also include a basin cover 900, which is located in a portion of the opening of the foot basin 100. The outlet of the spray pipe 820 may also be located under the basin cover 900, enabling multi-point spraying of detergent and clean water.

[0097] The spray pipe 820 is shared by both water spray and cleaning agent, which simplifies the structure and allows the spray assembly 800 to spray a mixture of cleaning agent and water before or during the cleaning component 300 cleans the back of the heel, thus achieving a better cleaning effect.
