Description

Technical Field

[0001] The present invention relates to a human body bathing and nursing machine, which is a mechanism for scrubbing the back of a human body. Background Art

[0002] When the human body is lying down or sitting to take a bath, the back, including the back part under the buttocks, requires a certain amount of operating space. The currently published "A bed with a bed surface that can form a convex and concave structure" (application number: 2024108475568), "A clothing and pants dressing and human back care mechanism in a supine position" (application number: 2025100117386), and "A lifting bed structure for facilitating human body care" (application number: 2024119052355) use the mechanical principle of forming a convex and concave structure by splicing the bed surface, thereby creating the necessary space for human body care operations in a supine position. Among them, applications 2024108475568 and 2025100117386 describe schemes for relatively staggered formation of a nursing work space, while application 2024119052355 describes an axle-wheel crawler-type body position movement structure that relatively lifts and staggers to create a work space. The slat unit of this scheme is fixed, and the creation of the nursing work space is achieved by relying on the rise of the axle-wheel crawler unit. It should be noted that the "first bed board and the second bed board" described in 2024108475568, the "first, second and third bed boards" described in 2025100117386, and the axle-wheel crawler-type spliced ​​bed surface described in 2024119052355 are independent and different bed surface structures.

[0003] The present invention is an expanded research based on the above-mentioned published application. First, the connection method of the axle wheel to the bed frame and the movement method of the scrubbing component are changed. Second, the structure that is simply used for the bed surface is expanded to be used for bath oranges and bathtubs, so that the lower buttocks of weak people who need to use bath oranges or bathtubs for bathing can also create a working space for scrubbing. Summary of the Invention The invention discloses a combined bed surface, which is composed of an axle-wheel track body displacement part and a lifting and lowering slatted bed surface patching part to form a complete bed surface. The main structure is expanded and applied to the inside of a bathtub and a bathtub, and is equipped with a scrubbing component.

[0004] In one solution, the entire bed surface is composed of a group of multiple axle wheel track assemblies and another group of multiple lifting and lowering assemblies. A scrubbing assembly that can be shifted and lifted and operated by a motor is provided below the axle wheel track assembly. The two ends of the above-mentioned axle wheel track assembly and the scrubbing assembly are movably fixed to the bed frame. The lifting assembly is connected and fixed to the upper end of the lifting (hydraulic) mechanism. The lifting mechanism is connected to the bed frame. The bed frame is provided with a rail groove for sliding and shifting the scrubbing assembly. The longitudinal push-pull mechanism is fixed to the bed frame and is connected to the connecting rod of the scrubbing assembly in the rail groove. The outer end of at least one axle wheel of the axle wheel track assembly has a transmission gear, and a manual or electric device is fixed to the outer end of the bed frame as a power source. The transmission gears of each axle wheel track are connected by a chain.

[0005] In one solution, the entire bed surface is composed of a group of multiple axle wheel track assemblies and another group of multiple lifting assemblies. The lifting assemblies are connected to the lifting (hydraulic) mechanism, which is connected to the bed frame. The axles of the axle wheel track assemblies are installed on the bed frame, and at least one axle end is installed with a transmission gear. A manual or electric device that drives the transmission gear and the track to move is provided on the bed frame, and each transmission gear is connected by a chain.

[0006] In one solution, the surface of the bathtub is composed of a double-axle wheel track assembly and a lifting assembly. The wheel axles are fixed to the frames on both sides and can rotate flexibly. A transmission gear that receives power from a transmission chain is installed at the end of at least one axle of each axle wheel track assembly. A manual or electric power source mechanism is set on the frame. The bathtub is equipped with a hollow movable backrest and a handheld scrubber.

[0007] In one solution, the bath orange is set in the bathtub and can be fixed to the tub body by means of screws or the like. The orange surface is composed of shaft-wheel track assemblies arranged at intervals and fixed to the orange frame by axles and can rotate. At least one shaft head of each shaft-wheel track assembly is installed with a gear that can accept chain drive. The manual or electric power source mechanism is set on a lifting arm that is higher than the bathtub to the outside of the tub.

[0008] In one scheme, the axle-wheel track assembly is composed of three axle wheels and tracks. Except for one axle equipped with a chain-driven active transmission gear, the rest are driven wheels. The tracks fit tightly against the axle wheels. The upper part of the lifting assembly is in the shape of a strip, and the lower part is connected to the lifting (hydraulic) mechanism.

[0009] In one solution, the track of the axle wheel track assembly can have a double-layer structure, with the inner layer being responsible for fitting with the axle wheel, and the outer layer being made of skin-friendly material (such as silicone and rubber).

[0010] In one scheme, the scrubbing component is composed of a rubbing wheel, a motor, a guide transmission, a reciprocating motion track, a fixed part, etc. A group of two or more rubbing wheels are installed at the head position of the scrubbing component. The rubbing wheel is shaft-shaped and divided into an inner and outer layer structure. The two ends of the inner core shaft are rotatably connected to the fixed part of the scrubbing component. The outer layer of the middle part of the shaft is disconnected and a transmission gear (with a diameter smaller than the rubbing wheel) is installed on the shaft. The outer layer of the rubbing wheel is in a circumferential oblique ridge shape and is wrapped with at least one layer of bath towel material (which can be equivalent to the material of the glove-type bath towel commonly used by people). The head of the component with the scrubbing wheel is installed with a motor as a whole and can reciprocate driven by a guide wheel track.

[0011] In one solution, the scrubbing component is a handheld scrubbing device, a scrubbing towel wheel is installed on the working head, and a transmission sprocket is connected to the motor at the end through the inner space of the extended handle.

[0012] The present invention changes the connection mode between the shaft-wheel track assembly and the bed body and the movement mode of the scrubbing assembly in the prior art, and expands its application to bathtubs and bathtubs. It can meet the needs of scrubbing the back or lower buttocks of the human body when lying or sitting or bathing in the bathtub. The scrubbing wheel structure installed on the head of the scrubbing assembly is more helpful to improve the scrubbing efficiency. Attached photos

[0037] The following are embodiments listed in conjunction with the accompanying drawings.

[0038] This embodiment is part of the embodiments of the present invention and should not be construed as limiting the embodiments of the present invention. For example, any assembly method, as long as it does not affect the internal spatial layout and operating principle of the device, shall fall within the scope of protection of the present invention. For example, the axle wheel track assembly can have three or four axles, or only one axle wheel when the axle wheel specifications are enlarged. The lifting mechanism of the lifting assembly can be hydraulic, a screw-driven lifting structure, or a crank-connecting rod lifting and lowering structure. The assembly order and position of each component can be interchanged. Example 1

[0039] The entire bed surface is composed of a group of multiple axle wheel track assemblies 1 and another group of multiple lifting and lowering assemblies 2. A scrubbing assembly 3 that can be shifted, lifted and operated by a motor is provided below the axle wheel track assembly 1. The two ends of the above-mentioned axle wheel track assembly 1 and the scrubbing assembly 3 are movably fixed to the bed frame 4. The lifting and lowering assembly 2 is connected and fixed to the upper end of the lifting (hydraulic) mechanism 2-1. The lifting mechanism 2-1 is connected to the bed frame 4. The bed frame 4 is provided with a rail groove 5 for sliding and shifting the scrubbing assembly 3. A longitudinal pushing and pulling mechanism 6 is fixed to the bed frame 4 and is connected to the connecting rod of the scrubbing assembly 3 in the rail groove. The outer end of at least one axle wheel of the axle wheel track assembly 1 has a transmission gear 1-1, and a manual or electric device 7 is fixed to the outer end of the bed frame 4 as a power source. The transmission gears 1-1 of each axle wheel track 1 are connected by a chain 8.

[0040] It should be noted that the height of the axle wheel crawler described in this embodiment remains stationary, and a space is formed between each two axle wheel crawler assemblies, and the axle wheel drives the crawler to rotate. When a group of multiple axle wheel crawlers rotate synchronously, the position of the human body lying on it also moves, that is, the position of the human body pressed on the crawler will move to the spatial position. At this time, the scrubbing assembly shifts to this space to scrub the human body at the mouth of the space, and the rise of the scrubbing assembly 3 can be achieved by the lifting of the lifting assembly. Through the shifting, the back of the human body is alternately in the spatial position for scrubbing. After scrubbing is completed, the scrubbing assembly falls, and the axle wheel crawler assembly moves again. After moving back and forth and scrubbing two or three times, the entire back of the human body can be scrubbed. Then the scrubbing assembly returns to its original position, and the lifting and lifting assembly rises to the spatial position. Since the upper part of the assembly is a flat strip, it automatically assembles with the axle wheel crawler assembly to form a bed surface. Example 2

[0041] The entire bed surface is composed of a group of multiple shaft wheel track assemblies 1 and another group of multiple lifting assemblies 2. The lifting assemblies 2 are connected to the lifting (hydraulic) mechanism 2-1, which is connected to the bed frame 4. The axle of the shaft wheel track assembly 1 is installed on the bed frame 4, and at least one axle end is installed with a transmission gear 1-1. A manual or electric device 7 that drives the transmission gear 1-1 and the track movement is provided on the bed frame 4, and each transmission gear 1-1 is connected by a chain 8.

[0042] It should be noted that, driven by a manual or electric device 7, the axle wheel track assembly can rotate through the gear 1-1 and the chain 8, and the human body lying on it is displaced by relying on the track. At this time, the lifting and lifting assembly 2 is in a non-rising state, and a space is formed between every two axle wheel track assemblies, which is convenient for scrubbing the human body parts lying on it. This embodiment does not have a scrubbing assembly, but is replaced by a handheld scrubbing device. After scrubbing is completed, the lifting and lifting assembly rises to the space, and the upper part is flush with the axle wheel track plane, forming a bed surface with it. Example 3

[0043] The surface of a bathtub is composed of an axle-wheel track assembly 1 and a lifting assembly 2. The wheel axle is fixed to both sides of an bathtub frame 4. The end of at least one axle of each axle-wheel track assembly 1 is equipped with a transmission gear 1-1 for receiving power from a transmission chain 8. A manual or electric power source mechanism 7 is arranged on the bathtub frame 4. A hollow movable backrest 9 is installed in an integral part of the bathtub. The scrubbing assembly 3 is replaced by a handheld scrubbing device.

[0044] It should be noted that the bathing orange surface is arranged at intervals by axle-wheel tracks. When a weak bather needs to sit and scrub the area below the buttocks, the axle-wheel track assembly can be driven to move the body position so that the area below the buttocks and thighs are alternately positioned in space for easy scrubbing. In order to avoid excessive complexity of the bathing orange components and to facilitate flexible operation, the mechanical integrated scrubbing assembly is changed to a handheld scrubbing device. Example 4

[0045] In one embodiment, the bathtub is set in the bathtub and can be fixed to the tub body by means of screws or the like. The bathtub surface is composed of shaft-wheel track assemblies 1 arranged at intervals and fixed to the bathtub frame by axles and can rotate. At least one shaft head of each shaft-wheel track assembly 1 is installed with a gear 1-1 that can accept chain drive. A manual or electric power source mechanism 7 is set on a lifting arm 11 that is higher than the bathtub to the outside of the tub.

[0046] It should be noted that the bath orange can be placed in the bathtub and driven by the power mechanism on the lifting arm 11. The axle-wheel track assembly can shift the human body sitting on the orange surface, and the lower part of the buttocks is alternately located in the space of the two axle-wheel track assemblies for manual scrubbing. Example 5

[0047] In one embodiment, the axle-wheel track assembly 1 is composed of three axle wheels and a track. Except for one axle equipped with an active transmission gear 1-1 for receiving the chain 8, the rest are driven wheels 1-2. The track 1-3 fits tightly with the axle wheel 1-2. The upper part of the lifting assembly 2 is in the shape of a strip, and the lower part is connected to the lifting (hydraulic) mechanism 2-1.

[0048] In one embodiment, the track 1-3 of the axle wheel track assembly 1 can be a double-layer structure, the inner layer is responsible for fitting with the axle wheel 1-2, and the outer layer is made of skin-friendly material (such as silicone and rubber).

[0049] In one embodiment, the scrubbing component 3 is composed of a rubbing wheel 3-1, a motor 3-2, a guide transmission 3-3, a reciprocating motion track 3-4, a fixed part, etc. A group of two or more rubbing wheels 3-1 are installed at the head position of the scrubbing component 3. The rubbing wheel 3-1 is shaft-shaped and divided into an inner and outer layer structure. The two ends of the core shaft of the inner layer are rotatably connected to the fixed part of the scrubbing component 3. The outer layer of the middle part of the shaft is disconnected and a transmission gear 3-3 (with a diameter smaller than the rubbing wheel) is installed on the shaft. The outer layer of the rubbing wheel 3-1 is in a circumferential oblique ridge shape and is wrapped with at least one layer of bath towel material (which can be equivalent to the material of the glove-type bath towel commonly used by people). The component head with the scrubbing wheel 3-1 is installed, the motor is integrated, and can reciprocate driven by a guide wheel track 3-4.

[0050] In one embodiment, the scrubbing component 3 is a handheld scrubbing device, a scrubbing towel wheel 3-1 is installed on the working head, and the transmission sprockets 3-3 and 3-4 are connected to the motor 3-2 at the end through the inner space of the extended handle.
