Description

Technical Field

[0001] This invention belongs to the field of medical nursing equipment technology, specifically referring to an electric scraping device for traditional Chinese medicine nursing. Background Technology

[0002] Gua sha, a traditional Chinese medicine external therapy, involves scraping the body surface to unblock meridians and promote blood circulation, effectively relieving muscle fatigue and improving local circulation. With its widespread clinical application, electric gua sha devices are gradually replacing manual operation and have become an important tool in the field of traditional Chinese medicine nursing.

[0003] However, existing electric gua sha devices still have significant shortcomings: the gua sha board and the device are mostly fixed by simple plug-in or screws, which is inconvenient to install and disassemble, and is prone to loosening during use, affecting operational stability and safety; there is a lack of an active adjustment mechanism for the fit between the gua sha board and the skin, making it difficult to adapt to different body parts, and the release of essential oils depends on manual application or passive dripping, which cannot achieve automatic quantitative supply, and uneven lubrication can easily cause skin friction damage; in addition, existing products lack integrated control of functions such as gua sha board heating, essential oil release and adsorption fixation, making it difficult to meet the needs of precise and comfortable operation. Summary of the Invention

[0004] In response to the above issues, and to overcome the problems of unstable gua sha boards, lack of skin-adhesion adjustment mechanisms, inconvenient essential oil release, and low degree of functional integration in existing gua sha devices, this invention provides an electric gua sha device for traditional Chinese medicine nursing, which effectively solves the problems of easily loosened gua sha boards, difficulty in adapting to different body parts, uneven essential oil lubrication, and insufficient intelligent operation of gua sha devices currently on the market.

[0005] The technical solution adopted by this invention is as follows: This invention provides an electric scraping device for traditional Chinese medicine nursing, including a hand-held shell, an automatic scraping board fixing device, an adsorption-type essential oil release structure, and a scraping board device. The hand-held shell is equipped with a control circuit, and an adjustment button is provided on the outer wall of the hand-held shell. The automatic scraping board fixing device is fixedly installed on the inner wall of the hand-held shell. The adsorption-type essential oil release structure is engaged and rotatably installed on the inner wall of the hand-held shell, and two sets of adsorption-type essential oil release structures are respectively arranged on both sides of the automatic scraping board fixing device. The scraping board device is engaged and installed in the automatic scraping board fixing device.

[0006] Furthermore, the automatic fixing device for the scraping board includes a snap-fit ​​clamping structure and a clamping self-locking structure. The snap-fit ​​clamping structure is in contact with the scraping board device, and the clamping self-locking structure is connected to the snap-fit ​​clamping structure. The clamping self-locking structure is fixedly installed on the inner wall of the hand-held housing. The clamping structure includes a limiting support bracket, a clamping plate, an adjusting plate, a limiting triangular slider, a limiting rack, and an adjusting gear. The limiting support bracket is fixedly mounted on the inner wall of the hand-held housing. A slide rail is provided on the inner wall of the limiting support bracket. The limiting triangular slider slides along the slide rail on the limiting support bracket. The clamping plate is fixedly mounted on the bottom wall of the limiting triangular slider. The limiting rack slides through the top wall of the limiting support bracket. The adjusting plate is fixedly mounted on the bottom wall of the limiting rack and slides along the inclined surface of the limiting triangular slider. The adjusting gear is rotatably mounted on the inner wall of the hand-held housing. The limiting rack meshes with the adjusting gear.

[0007] Furthermore, the cross-section of the adjusting plate is designed as a trapezoidal structure, and the inclined surface of the adjusting plate is provided with a protruding ridge. The inclined surface of the limiting triangular slider is provided with a groove. The protruding ridge on the adjusting plate engages and slides along the groove on the limiting triangular slider. The limiting triangular slider and the limiting support bracket are connected by a spring. After the top wall of the adjusting plate contacts the scraping board device, the adjusting plate rises, the inclined surface of the limiting triangular slider contacts and slides against the side of the adjusting plate, and the limiting triangular slider moves in the direction of the limiting rack, thereby fixing the scraping board device with the clamping plate.

[0008] Furthermore, a rubber layer is provided on the contact surface between the clamping plate, the adjusting plate and the scraping board device, which can improve the stability of the scraping board device fixed in the hand-held housing.

[0009] Furthermore, the clamping self-locking structure includes a limiting ring, a ratchet, a limiting block, and a blocking block concealment groove. The limiting ring is fixedly installed on the inner wall of the hand-held housing. The blocking block concealment groove is installed on the inner wall of the limiting ring. The limiting block is engaged and rotatably installed on the blocking block concealment groove. A torsion spring is provided at the engagement point of the limiting block and the blocking block concealment groove. The ratchet is concentrically arranged with the limiting ring. The ratchet and the adjusting gear are fixedly connected by a bracket.

[0010] Furthermore, both the card block hiding slot and the limiting card block are equipped with electromagnets. When the two sets of electromagnets are energized, they attract each other, which can cause the limiting card block to contact and separate from the ratchet, allowing the scraping board device to detach from the hand-held housing.

[0011] Furthermore, the adsorption-type essential oil release structure includes an air pump, a suction cup structure, a hose, an adjusting motor, a hinge joint, a liquid storage tank, rollers, and a draining tank. The air pump is fixedly installed on the inner wall of the handheld housing, the hose is fixedly connected to the air pump, the suction cup structure is fixedly connected to the hose, the adjusting motor is fixedly installed on the inner wall of the handheld housing, the hinge joint is fixedly installed on the top wall of the suction cup structure, and the rotor of the adjusting motor is connected to the hinge joint. When the adjusting motor is energized, the suction cup structure rotates, causing the suction cup structure to adhere to the skin. The liquid storage tank is located on the side wall of the suction cup structure, and the rollers roll close to the skin. The draining tank is connected to the liquid storage tank to drain the lubricant in the storage tank to the body surface for facilitating the scraping operation.

[0012] Furthermore, the side wall of the suction cup structure is provided with a telescopic sealing plate, a telescopic plate slot, a one-way limiting groove, a sealing ball, a connecting conduit, a small spring A, and a small spring B. The telescopic plate slot is set on the side wall of the suction cup structure, and the telescopic sealing plate slides along the telescopic plate slot. The one-way limiting groove is set inside the suction cup structure, and the sealing ball is set in the one-way limiting groove. The two ends of the small spring A are respectively connected to the sealing ball and the one-way limiting groove. The connecting conduit is fixedly set on the top wall of the telescopic sealing plate, and the two ends of the small spring B are respectively connected to the telescopic sealing plate and the telescopic plate slot. When the connecting conduit moves upward, the sealing ball is lifted, and the lubricating liquid such as essential oil in the liquid storage tank flows out onto the skin, which facilitates the operation of the gua sha board and reduces the friction damage to the body caused by the movement of the gua sha board.

[0013] Furthermore, the side wall of the connecting conduit is provided with small holes, which can discharge the essential oil in the one-way limiting groove.

[0014] Preferably, to improve the automaticity of essential oil release from the storage tank, a solenoid valve is installed in the drain tank. When energized, the valve opens, and the essential oil flows out and comes into contact with the skin. After the previous telescopic sealing plate comes into contact with the skin, the telescopic sealing plate moves up, releasing the essential oil through the connecting tube.

[0015] Furthermore, the inner wall of the handheld housing is provided with a controller and an energy storage battery, the outer wall of the handheld housing is provided with a charging connector, a wire is provided between the charging connector and the energy storage battery, a wire is provided between the controller and the energy storage battery, and a data cable is provided between the controller and the adjustment button, the adjustment motor, the air pump, the solenoid valve, the electromagnet, and the scraping board device.

[0016] Furthermore, the scraping board device consists of two parts: the bottom wall of the scraping board device is made of metal, and the top wall of the scraping board device is made of insulating material. The bottom wall of the adjustment plate is provided with conductive pins, and the top of the scraping board device is provided with pin slots. After the scraping board device is inserted into the adjustment plate, the bottom wall of the scraping board device is powered on, and then the scraping board device can be heated by operating the adjustment button.

[0017] Furthermore, the top wall of the hand-held shell is provided with a recessed area, which is conducive to gripping with the thumb and forefinger. The bottom wall of the hand-held shell is provided with a sealing plate made of rubber material. The sealing plate is connected to the suction cup structure with a highly elastic material. When the suction cup structure rotates, it can deform to ensure the suction cup structure's adsorption effect on the skin.

[0018] This solution provides an electric scraping device for traditional Chinese medicine nursing, which has the following beneficial effects: (1) By setting up an automatic fixing device for the scraping board, the present invention utilizes the linkage between the limiting triangular slider, the adjusting plate and the limiting rack in the clamping structure, combined with the one-way limiting effect of the ratchet and the limiting block in the clamping self-locking structure, to realize the rapid insertion and stable locking of the scraping board device, effectively preventing the scraping board from loosening or falling off during the scraping process. At the same time, the unlocking is controlled by an electromagnet, which facilitates the replacement and cleaning of the scraping board, significantly improving the safety and convenience of operation. (2) This invention sets up an adsorption-type essential oil release structure, uses the adjustment motor to drive the hinge joint to adjust the angle of the suction cup structure, and uses an air pump to make the suction cup structure firmly adsorbed on the body surface, ensuring that the scraping board device is always in close contact with the skin during the movement. At the same time, through the linkage design of the electromagnetic valve or telescopic sealing plate and the connecting tube, the essential oil is automatically and quantitatively released during the scraping process, effectively reducing the frictional resistance between the scraping board and the skin, and improving the comfort and care effect of scraping. (3) The present invention integrates a controller, energy storage battery and adjustment button in the hand-held shell, realizing unified electronic control operation of the heating function of the scraping board device, the adsorption angle of the adsorption-type essential oil release structure and the essential oil discharge. Users can flexibly adjust according to the scraping part and the strength requirements. At the same time, the concave design of the top wall of the hand-held shell and the sealing plate structure of the bottom wall improve the grip stability and sealing performance. The overall structure is compact and the operation is intelligent, which is suitable for various scraping scenarios in traditional Chinese medicine nursing. Attached Figure Description

[0026] The scraping board device 4 consists of two parts: the bottom wall of the scraping board device 4 is made of metal, and the top wall of the scraping board device 4 is made of insulating material.

[0027] The top wall of the hand-held housing 1 has a recessed area, which is conducive to gripping with the thumb and forefinger. The bottom wall of the hand-held housing 1 has a sealing plate 37 made of rubber material.

[0028] The automatic fixing device 2 for scraping board includes a snap-fit ​​clamping structure 5 and a clamping self-locking structure 6.

The ratchet 14 is concentrically arranged with the limiting ring 13. The ratchet 14 is fixedly connected to the adjusting gear 12 through a bracket.

[0032] Both the card block hiding slot 16 and the limiting card block 15 are equipped with electromagnets.

[0033] The adsorption-type essential oil release structure 3 includes an air pump 17, a suction cup structure 18, a hose 19, an adjusting motor 20, a hinge joint 21, a liquid storage tank 22, a roller 23, and a draining tank 24. The air pump 17 is fixedly installed on the inner wall of the hand-held housing 1. The hose 19 is fixedly connected to the air pump 17. The suction cup structure 18 is fixedly connected to the hose 19. The adjusting motor 20 is fixedly installed on the inner wall of the hand-held housing 1. The hinge joint 21 is fixedly installed on the top wall of the suction cup structure 18. The rotor of the adjusting motor 20 is connected to the hinge joint 21. The liquid storage tank 22 is located on the side wall of the suction cup structure 18. The roller 23 rolls close to the skin. The draining tank 24 is connected to the liquid storage tank 22.

[0034] The suction cup structure 18 has a telescopic sealing plate 25, a telescopic plate slot 26, a one-way limiting groove 27, a sealing ball 28, a connecting conduit 29, a small spring A30, and a small spring B31 on its side wall. The telescopic plate slot 26 is located on the side wall of the suction cup structure 18, and the telescopic sealing plate 25 slides along the telescopic plate slot 26. The one-way limiting groove 27 is located inside the suction cup structure 18, and the sealing ball 28 is located in the one-way limiting groove 27. The two ends of the small spring A30 are connected to the sealing ball 28 and the one-way limiting groove 27, respectively. The connecting conduit 29 is fixedly located on the top wall of the telescopic sealing plate 25 and is slidably sealed to the one-way limiting groove 27. The two ends of the small spring B31 are connected to the telescopic sealing plate 25 and the telescopic plate slot 26, respectively. The side wall of the telescopic sealing plate 25 is provided with a rotating roller 23, and a drainage groove 24 is located inside the telescopic sealing plate 25.

[0035] Small holes are provided on the side wall of the connecting conduit 29.

[0036] A solenoid valve 32 is installed in the drain tank 24. When energized, the valve opens, and the essential oil flows out and comes into contact with the skin.

[0037] In actual use, select a gua sha board device 4 with a suitable shape, insert the gua sha board device 4 into the slot on the bottom sealing plate 37 of the hand-held housing 1, insert the pin on the bottom wall of the adjusting plate 9 into the pin slot on the top wall of the gua sha board device 4, and turn on the electric heating plate inside the gua sha board device 4. After the scraping board device 4 comes into contact with the adjusting plate 9, the adjusting plate 9 slides in the vertical direction. The limiting triangular slider 10 is affected by the elastic force of the spring. When the adjusting plate 9 rises, the limiting triangular slider 10 loses the support of the adjusting plate 9 and slides in the direction of the limiting rack 11. The clamping plate 8 clamps the scraping board device 4. To prevent the scraping board device 4 from detaching from the clamping plate 8, when the limiting rack 11 moves upward, the adjusting gear 12 rotates, and the ratchet 14 rotates with the adjusting gear 12. During the process of the limiting rack 11 rising, the ratchet 14 presses the limiting block 15, causing the limiting block 15 to rotate and hide in the block hiding groove 16. When the limiting rack 11 slides downward, the adjusting gear 12 reverses, but when the ratchet 14 rotates in the opposite direction, the limiting block 15 is pressed by the ratchet 14. The limiting block 15 is close to the edge of the block hiding groove 16 and cannot rotate and is hidden in the block hiding groove 16. The ratchet 14 cannot rotate due to the limiting effect of the limiting block 15, thereby ensuring the relative stability of the clamping plate 8 and the scraping board device 4. According to the conventional scraping operation, adjust the angle between the scraping board and the body surface, adjust the motor 20 to work, control the hinge joint 21 to rotate, and change the angle between the suction cup structure 18 and the hand-held outer shell 1, so that the suction cup opening of the suction cup structure 18 is perpendicular to the skin surface. Turn on the air pump 17 to make the suction cup structure 18 adhere to the body surface, ensuring that the scraping board device 4 is always in close contact with the skin during the scraping process. When the gua sha board is moved, the roller 23 on the bottom wall of the suction cup structure 18 rolls on the skin. The suction force of the suction cup is less than the pulling force of the manually moved device. By pressing the adjustment button 36, the controller 33 controls the solenoid valve 32 to be open, and the essential oil in the liquid tank 22 is discharged and enters the skin surface, reducing the frictional resistance between the gua sha board and the skin. If the telescopic sealing plate 25 is used, the controller 33 is not needed to control the automatic release of essential oil during the scraping process. When the telescopic sealing plate 25 is pressed on the skin surface, the connecting tube 29 is inserted into the one-way limiting groove 27, the sealing ball 28 is displaced, and the liquid in the reservoir 22 is discharged to the body surface through the connecting tube 29. The essential oil will only be released when the suction cup structure 18 is attached to the skin for scraping. During the scraping process, the operation adjustment button 36 heats the scraping board device 4 to improve the scraping effect; When it is necessary to release the scraping board device 4, the electromagnets on the surface of the limiting block 15 and the hidden slot 16 are energized and attracted, and the ratchet 14 loses the restriction of the limiting block 15, so that the scraping board device 4 can be pulled out from between the clamping plates 8.

[0039] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
