[0044] In the process of coating medicine, in order to ensure better absorption effect, the driving sleeve 9 is further provided with a coating massage mechanism 31, the driving sleeve 9 comprises a driving upper sleeve 32 and a driving lower sleeve 33, the driving lower sleeve 33 is telescopic arranged in the driving upper sleeve 32, and a spring is arranged between the driving upper sleeve 32 and the driving lower sleeve 33, the coating massage mechanism 31 comprises a massage driving shell 34, a driving rod 35, a push rod 36, an adjusting rod 37, a connecting rod 38, an output rod 39 and a massage motor 40, the driving rod 35 is rotatably arranged in the massage driving shell 34, the push rod 36 is hinged with the driving rod 35, the adjusting rod 37 and the connecting rod 38 are both hinged on the push rod 36, an arc-shaped adjusting groove 41 is arranged in the massage driving shell 34, a sliding block 42 is rotatably arranged on the adjusting rod 37, the sliding block 42 is provided with a sliding head, the sliding block 42 slides in the adjusting groove 41 through the sliding head, the output rod 39 is hinged with the connecting rod 38, the output rod 39 slides out of the massage driving shell 34 and is fixedly connected with the driving lower sleeve 33, when the driving rod 35 rotates, the push rod 36 drives the connecting rod 38 to push, and then the connecting rod 38 drives the output rod 39 to reciprocatingly slide, and acts on the driving lower sleeve 33, so that the driving lower sleeve 33 slides up and down with small amplitude, and then acts on the variable form framework assembly 7, so that the variable form framework assembly 7 realizes small amplitude grabbing and releasing action, simulates the effect of human hand to grab and release and massage, and then acts on the affected area, which not only improves the absorption effect, but also improves the comfort, the massage motor 40 is arranged on the massage driving shell 34 and the output end is connected with the driving rod 35; because the areas of different parts are different, different patients have different feelings on the amplitude of massage, therefore, the amplitude of the massage action of the coating mechanism 4 is adjustable, the adjusting screw rod 43 is threadedly connected on the sliding block 42, the screw gear 44 is arranged on the adjusting screw rod 43, the adjusting gear 45 is rotatably arranged in the massage driving shell 34, the adjusting gear 45 is engaged with the screw gear 44, the sleeve frame 46 is rotatably arranged on the adjusting gear 45, the adjusting gear 45 and the screw gear 44 are bevel gears, by rotating the adjusting gear 45, the screw gear 44 is driven to rotate, and then the adjusting screw rod 43 is driven to rotate, and then the sliding block 42 moves relative to the adjusting screw rod 43, and then the sliding block 42 slides in the adjusting groove 41, so that the position of the adjusting rod 37 changes, and then the movement amplitude of the connecting rod 38 changes, and then the telescopic amplitude of the output rod 39 changes, and then the telescopic amplitude of the driving lower sleeve 33 changes, and then the deformation amplitude of the coating mechanism 4 changes, so the massage effect changes.

[0045] The connecting head 47 is arranged above the variable body 12, the coating outer sleeve 5 is fixedly connected with the connecting head 47 and the bottom of each variable body 12, and then when the coating mechanism 4 deforms, the coating outer sleeve 5 also deforms, and the bottom forms a concave bowl shape or a flat disc shape.

[0046] The massage driving shell 34 is provided with an adjusting knob 48, the adjusting gear 45 is connected with a worm gear 49, the adjusting knob 48 is connected with a worm 50, and the adjusting knob 48 is connected with the adjusting gear 45 through the structure of the worm gear 49 and the worm 50.

[0047] The bottom surface of the coating cover 5 is provided with micro convex heads 51 which are distributed in a spiral around the discharge hole 20. During coating, the medicine is first discharged from the central discharge hole 20, and then, combined with the rotating force of the mechanism and the spiral distribution of the micro convex heads 51, the medicine is gradually and uniformly coated to the periphery. Since there are gaps between the micro convex heads 51, the ointment has higher freedom of movement when being coated and will not gather, so the coating is more uniform. At the same time, since the coating massage mechanism 31 can also make the coating mechanism 4 produce a grabbing action, when the ointment is driven to the periphery, the coating mechanism 4 can gather the ointment from the periphery to the central position again, and then perform coating again, thereby producing the effects of preventing the ointment from spreading and circulating the ointment from the center to the periphery repeatedly until the ointment is completely and uniformly absorbed, achieving unexpected effects in terms of coating effect and avoiding waste of the ointment.

[0048] The outer side of the bottom surface of the coating cover 5 is provided with an annular convex strip 52, which can avoid the ointment from being continuously gathered to the outer periphery of the bottom surface of the coating cover 5 due to the centrifugal effect during coating,

[0049] The coating cover 5 is made of thermoplastic elastomer (TPE), which has good flexibility and stretchability and can be stretched and deformed in a large range without being damaged.

[0050] When the mechanism is spread, the TPE film can be flatly unfolded to form a smooth plane; when the mechanism is gathered, the TPE film can closely fit the shape of the joint and will not produce wrinkles due to its good elastic recovery.

[0051] In an embodiment, the coating cover 5 can also be made of silicone rubber, which is a commonly used elastic material and has excellent flexibility, stretchability and high and low temperature resistance. Its molecular structure enables it to maintain good elasticity and shape stability in different temperature environments. The silicone rubber film can form a flat surface when unfolded, and the surface is smooth, which is conducive to uniform coating of the medicine. When gathered, the silicone rubber film can closely wrap the joint and adapt to the complex shape of the joint, and will not produce wrinkles due to its good elasticity. In addition, the silicone rubber also has good biocompatibility and will not cause irritation and allergic reactions to human skin and joint tissue, which is very suitable for coating film mechanisms that come into contact with the human body.

[0052] In use, first, the ointment is placed in the ointment box 16, and then the device is placed on the affected area. The motorized telescopic rod 15 is controlled to push the driving sleeve 9 to slide, and then the special-shaped long gear 53 of each variable form framework assembly 7 is pushed by the linkage rod 8 to rotate around the gear edge 10 of the special-shaped multi-surface tooth body 6. When one special-shaped long gear 53 rotates, the special-shaped long gears 53 connected thereto also rotate, and then each special-shaped long gear 53 rotates, so that each variable form framework assembly 7 is adjusted into an arc-shaped framework, and the coating sleeve 5 is also changed into a concave bowl shape, and then fits the affected area. The driving mechanism 2 drives the coating mechanism 4 to rotate, and the coating motor 21 drives the feeding auger 27 to rotate, and then the ointment is gradually input into the inner rod, and then is transmitted to the telescopic discharge pipe 18, and is discharged from the discharge hole 20. After the ointment is extruded from the center, the spiral micro convex head 51 gradually spreads the ointment outward to uniformly coat.

[0053] When coating, the coating massage mechanism 31 is started, the driving rod 35 rotates to drive the push rod 36 to push the connecting rod 38, and then the connecting rod 38 pushes the output rod 39 to reciprocatingly slide to drive the lower driving sleeve 33 to slide up and down, and then acts on the variable form framework assembly 7 to make the variable form framework assembly 7 realize a small amplitude gripping and releasing action, simulates the gripping and releasing and massage effect of the human hand, and then acts on the affected area, not only improves the absorption effect, but also improves the comfort, and also gathers the ointment on the periphery to the center to realize the effect of circulating coating.

[0054] When the massage amplitude needs to be adjusted, the adjusting knob 48 is rotated to rotate the adjusting gear 45 through the worm gear 49 and the worm 50 structure, and then the screw gear 44 is rotated to drive the adjusting screw 43 to rotate, and then the sliding block 42 moves relative to the adjusting screw 43, and then the sliding block 42 slides in the adjusting groove 41, so that the position of the adjusting rod 37 changes, and then the movement amplitude of the connecting rod 38 changes, and then the telescopic amplitude of the output rod 39 changes, and then the telescopic amplitude of the lower driving sleeve 33 changes, and then the deformation amplitude of the coating mechanism 4 changes, and thus the massage amplitude and effect change.

[0055] The above only describes the preferred embodiment of the patent, and does not limit the patent. Any modification, equivalent replacement and improvement made within the spirit and principle of the patent should be included in the protection scope of the patent.
