Description

Technical Field

[0001] The invention relates to a slapping device, in particular to an automatic auxiliary slapping board device. Background Art

[0002] Meridian tapping therapy is usually used clinically for acute or superficial symptoms, where the pain is located in a small area and is more comfortable than traditional scraping. It is a traditional green therapy that can improve the body's blood circulation, promote metabolism, and continuously improve the body's own immune function. This method is widely applicable in clinical practice and is used in the treatment of many diseases. Because of its simple operation, easy to carry instruments, and excellent efficacy, it can not only avoid the toxic and side effects caused by the use of drugs, but also save medical expenses, and is widely circulated.

[0003] The commonly used method of slapping is to slap a certain acupuncture point of the patient for a long time by holding a slapping board. The slapping board consists of a bendable and highly tough plastic handle and a slapping surface with several flexible convex points at one end. When using it, the slapping person holds the handle and swings it up and down, so that the board surface of the slapping board moves up and down with the swinging, and the handle bends and deforms with the swinging and forms a deformation force on the board surface, so that the convex points on the board surface can form a certain frequency and pressure of slapping under the action of the swinging force and the deformation force when contacting the acupuncture point. When the acupuncture point is slapped until the sha point appears and the number and color of the sha point meet the requirements, the slapping is stopped. However, since the slapping action needs to be completed manually, and the long-term slapping requires a lot of energy and time of medical staff, it will cause the problem of insufficient manpower of medical staff and high cost of each slapping. At the same time, for parts that cannot be directly touched, such as the back, patients cannot slap alone, which further aggravates the above problems.

[0004] In response to the above problems, some manufacturers are currently trying to develop an electric slapping board that replaces manual slapping with electric slapping. However, there are many difficulties in designing this electric slapping board. For example, the motor directly controls the slapping, which is prone to excessive force or too deep slapping due to operational errors, thus causing health damage to the patient. On the other hand, the slapping force of the existing slapping board is determined by the coordination of the swing amplitude and swing speed of the slapping board. Medical staff can make appropriate adjustments based on experience and patient feedback when slapping, but it is difficult to coordinate the two with the motor control method to flexibly adjust the slapping force. In addition, it is difficult to achieve excellent cupping effects with a single, constant slapping force. The reason is that the patient feels strong pain during the initial cupping, so a smaller slapping force is needed to keep the patient comfortable. The pain gradually decreases in the middle and late stages of cupping, and the cupping effect of the original slapping force gradually decreases, so the slapping force needs to be appropriately increased. However, it is difficult to achieve a gradual increase in the slapping force with the motor slapping method. If the swing speed is directly increased, it will cause a significant difference in the patient's feelings before and after, resulting in discomfort. Due to the above defects, the current electric cupping method cannot completely replace the manual slapping method to achieve cupping.

[0005] Therefore, there is a need for an electric slapping device with high safety and automatically adjustable slapping force. Summary of the invention

[0015] Compared with the prior art, the present invention has the following characteristics:

[0016] (1) The present invention can flexibly adjust the initial position of the third swing arm from three directions through the cooperation of the electric turntable, the first swing arm and the second swing arm, and make the third swing arm at a specified tilt angle after positioning, so that the scraping board can stably contact the scraping part after positioning; through the torsion spring between the scraping board and the third swing arm, the scraping board can drive the torsion spring to be pressed when the third swing arm swings, so that the deformation of the torsion spring is used to apply a rebound force to the scraping board, so that the rebound force and the swing inertia of the scraping board are used to control the slapping force; under the above cooperation, the present invention does not perform hard slapping by controlling the swing angle during slapping, but performs flexible slapping with a certain pressure by the scraping board, thereby effectively avoiding the problem of squeezing injury caused by hard slapping and improving the safety of patients;

[0017] (2) On the basis of the above, the present application can flexibly adjust the upper swing angle of the slapping board by setting the pressure adjustment component. When the swing angle of the slapping board changes, the extrusion deformation amplitude of the torsion spring also changes accordingly, and the slapping force on the slapping part after rebounding is also different; and under this coordination, the present application can change the limit height of the limit plate by adjusting the rotation angle of the adjustment rod, thereby realizing automatic adjustment of the slapping force of the slapping board, and the slapping force can be separated from the slapping frequency of the motor, thereby improving the slapping effect of the present invention, and the patient will not feel the obvious change in the slapping frequency; through the coordination of the control gear of the pressure adjustment motor, the present invention can divide the gear according to different slapping forces, and control the slapping force to change gradually during the slapping process, thereby realizing automatic adjustment of the slapping force;

[0018] (3) Through the angle adjustment assembly between the second swing arm and the third swing arm, the medical staff can accurately adjust and fix the angle of the third swing arm. On the one hand, the position accuracy of the scraping board is guaranteed, and the problem of the scraping board not being able to hit the target due to positioning deviation is avoided, thereby improving its scraping stability. On the other hand, the cooperation between the spline and the spline cylinder can also play a positioning effect after limiting, so that the flapping motor can accurately control the swing position of the third swing arm; at the same time, through the cooperation of the compression spring, the rotating shaft and the contact part, the third swing arm can be separated from the spline cylinder when the angle is adjusted, that is, the change of the swing angle of the third swing arm will not affect the angle and position of the spline cylinder, and then after the rotating shaft is reconnected, the eccentric wheel transmission assembly can keep the swing angle of the third swing arm consistent, that is, the change of the swing angle after the third swing arm is offset is avoided, and the working stability of the present application is further improved;

[0019] (4) By setting a camera on the second swing arm, the patient can also observe the color change and the appearance of the cupping area in real time, thereby improving the cupping control effect on the cupping area; with the above cooperation, the present application can effectively improve its safety and cupping effect, and enable patients to use it alone to achieve cupping on specific parts, effectively reducing the demand for medical staff or other auxiliary personnel;

[0020] Therefore, the present invention has the characteristics of high safety and automatic adjustment of the beating force. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the pressure cover 22 is provided with a limiting sleeve 23 extending into the placement cavity 302 . The limiting sleeve 23 is sleeved on the outside of the compression spring 16 .

[0036] The second swing arm 3 is provided with a camera 24, the shooting direction of the camera 24 is toward the scraping board 5 and the angle can be manually adjusted as needed. The scraping board device is provided with a control mainboard, and the outside of the control mainboard is respectively connected to the motors and the electric turntable 1, and can be connected to the mobile phone APP through the wireless connection module. After the connection, the user can control the rotation position and opening angle of the first swing arm 2 and the second swing arm 3 by mobile phone, and can set the scraping time, scraping frequency and scraping strength of the scraping board 5, and watch the captured image of the camera 24 through the mobile phone screen during the scraping process, so as to observe the scraping situation of the scraping part in real time; the scraping time is generally 2-3 minutes, and a single position cannot exceed 5 minutes at most.

[0037] The lower end of the electric turntable 1 is connected to a trolley 25 , and a brake mechanism is provided on the roller at the bottom of the trolley 25 .

[0038] Working principle of the present invention: When the present invention is used, the slapping board device is first moved to the designated position and fixed by the cart 25, and then the slapping board device is turned by the electric turntable 1, and the opening angles of the first swing arm 2 and the second swing arm 3 are adjusted by the motor in turn, so that the slapping board 5 reaches the required height position and extension length, that is, close to the slapping part. When the slapping board 5 is close to the slapping part, the operator pulls out the third swing arm 4 through the hand lever 17 to separate the spline 14 and the spline cylinder 15 from each other, and at the same time, the annular plate of the rotating shaft 13 squeezes the compression spring 16 and fits the limit sleeve 23; at this time, the third swing arm 4 and the eccentric wheel transmission assembly are in a state of separation from each other, that is, the rotation of the third swing arm 4 will not cause excessive displacement of the transmission rod 26, and will not affect the starting slapping position. After the hand lever 17 is pulled out, it rotates and drives the third swing arm 4 to swing along the rotating shaft 13, so that the scraping board 5 moves to the contact scraping part, and the scraping board 5 is slightly higher than the lower limit plate 12 after positioning, that is, the torsion spring 6 is in a slightly extruded deformation state.

[0039] After the third swing arm 4 is in place, release the hand lever 17 so that the spline 14 is buckled back into the spline tube 15 under the drive of the compression spring 16, so that the third swing arm 4 and the eccentric wheel transmission assembly resume the linkage state. When the device is in action, the spline tube 15 is driven to rotate back and forth by the flapping motor 18 through the eccentric wheel transmission assembly, and the spline tube 15 drives the third swing arm 4 to swing back and forth at a specified frequency through the rotating shaft 13. The user can adjust the speed of the flapping motor 18 through the mobile phone APP to control the flapping frequency. When the third swing arm 4 swings upward, it will drive the slapping plate 5 to swing upward, so that after the third swing arm 4 moves to the highest position, the slapping plate 5 continues to move upward under the action of inertia and squeezes the torsion spring 6 until the end of the slapping plate 5 contacts the upper limit plate 9. When the third swing arm 4 falls, the slapping board 5 falls with the third swing arm 4 and maintains the compression state of the torsion spring 6 under the action of inertia; when the third swing arm 4 falls to a low position, the slapping board 5 continues to swing downward under the action of inertia and the rebound force of the torsion spring 6, and contacts the slapping part during the falling process, thereby utilizing inertia and rebound force to realize the slapping action. When contacting the slapping part, there is still a gap between the slapping board 5 and the lower limit plate 12, thereby ensuring the integrity of the slapping action. The slapping board 5 can be limited by the lower limit plate 12 to prevent the slapping board 5 from swinging excessively after the slapping part is separated, causing a collision, so that the swing range of the slapping board 5 is stable and controllable.

[0040] During the slapping process, the limit height of the upper limit plate 9 can be adjusted in real time by the pressure regulating motor 11; when the height of the upper limit plate 9 changes, the swing distance of the slapping plate 5 changes accordingly, which in turn causes the change in the deformation amplitude of the compression spring 16; and the greater the deformation amplitude of the compression spring 16, the greater the slapping force formed by the compression spring 16 when driving the slapping plate 5 to rebound, thereby realizing the real-time adjustment of the slapping force of the present invention. With the above-mentioned structure, the slapping force of the present invention can be independent of the swing range and swing frequency of the third swing arm 4, so that on the one hand, the user can adjust the above parameters separately to achieve the most comfortable slapping effect; on the other hand, the slapping force will not cause obvious differences in the slapping frequency after the change, that is, the consistency of the entire slapping action is maintained to avoid discomfort to the user.

[0041] During the slapping process, the user can also use the mobile phone to connect the camera 24 to observe the color and the appearance of the slapping area in real time, so as to ensure the stability of the slapping and avoid excessive slapping without the user's knowledge to cause skin damage.
