Abstract

This invention relates to the field of Gua Sha technology and discloses a Gua Sha device with multi-point liquid dispensing, including a handle, a pressing plate inside the handle, a piston rod at the bottom of the pressing plate, a piston head at the bottom of the piston rod, and a limiting mechanism inside the handle.

A liquid storage chamber is provided at the top of the piston head, and a Gua Sha plate body is provided at the top of the handle. This invention features multiple buttons on the side of the handle, allowing for control of the liquid dispensing volume to suit different areas such as the hands and back. The damping ring on the outer edge of the piston head moderately slows down the pressing speed, resulting in a more stable oil seepage and reducing instantaneous gushing. This helps to form a relatively uniform oil film below the Gua Sha working surface, improving the uneven lubrication problem caused by traditional single-point liquid dispensing.

Description

Technical Field

[0001] This invention relates to the field of scraping therapy technology, specifically a scraping device that allows for fluid output from multiple sites. Background Technology

[0002] In patent application CN221266629U, a main shell is included, with a scraping blade disposed at the bottom of the main shell and liquid outlets located on one or both sides of the scraping blade at the bottom of the main shell; a liquid storage component disposed within the main shell, in which scraping oil is stored; and a pressing component mounted on the main shell, through which scraping oil in the liquid storage component is squeezed out from the liquid outlets. The advantages are: integrating the scraping blade with the pressing component and the liquid storage component allows the scraping oil to be continuously squeezed out during the scraping process, greatly improving the convenience and efficiency of scraping; traditional scraping requires frequent interruptions to manually apply scraping oil, which not only affects the continuity of scraping but may also affect the therapeutic effect. This invention, through the mechanism of manually squeezing out scraping oil, effectively maintains the continuity of the treatment process, improves the therapeutic effect, simplifies the operation steps, and makes the scraping process more convenient and faster.

[0003] In the prior art, including the aforementioned patents, most existing gua sha devices have separate oil outlets and gua sha board surfaces. After the oil flows out, it is necessary to wait for the board surface to move before it can be scraped, resulting in lubrication lag. There are usually only one or two oil outlets, and the oil accumulates in spots and is not spread evenly. When pressing to dispense oil, there is a lack of gear adjustment and damping control, resulting in either wasted spray or insufficient output. In addition, single-channel oil delivery is difficult to extend to large-area synchronous liquid output, resulting in poor operation feel and low efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved Based on this, the purpose of this invention is to provide a scraping device with multi-site liquid outlets to solve the technical problems in the prior art, such as the oil outlet being separated from the scraping board surface, requiring the board surface to be moved after the oil flows out before it can be scraped, resulting in lubrication lag; the oil outlets usually only have one or two, causing the oil to accumulate in spots and spread unevenly; the lack of gear adjustment and damping control when pressing to dispense oil, resulting in either excessive gushing or insufficient output; in addition, single-channel oil delivery is difficult to extend to large-area simultaneous liquid outlets, leading to poor operating feel and low efficiency.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a scraping device with multi-part liquid output, comprising a handle, a pressing plate disposed inside the handle, a piston rod disposed at the bottom end of the pressing plate, a piston head disposed at the bottom end of the piston rod, a limiting mechanism disposed inside the handle, the limiting mechanism comprising a button, a sliding block, a sliding column, a locking block, a sliding plate, a limiting post, a second spring, and a wedge block, the button being disposed on the outside of the handle, the sliding block being disposed at the bottom end of the button, the sliding column being disposed on one side of the sliding block, the locking block being disposed at the top end of the sliding plate, the sliding plate being disposed inside the handle, the limiting post being disposed inside the sliding plate, the second spring being disposed on the outside of the limiting post, the wedge block being disposed at the top end of the sliding plate, a liquid storage chamber being disposed at the top end of the piston head, an oil distribution pipe being connected to the bottom end of the liquid storage chamber, a manifold assembly being connected to the top end of the oil distribution pipe, and a scraping plate body being disposed at the top end of the handle.

[0006] By adopting the above technical solution, when a staff member presses a certain number key, the key moves downward and presses the sliding block fixed at its bottom. The sliding block moves in a fixed direction under the constraint inside the handle. When the sliding block moves downward, the sliding column linked to it also moves downward synchronously. The lower end of the sliding column has an inclined surface, which slides downward along the upper inclined surface of the locking block and applies pressure. The locking block is fixed to the sliding plate. When the sliding column presses down, it forces the sliding plate to move downward. A return spring is provided behind the sliding plate inside the handle, which is compressed and stores force to provide energy for subsequent reset.

[0007] Furthermore, the bottom end of the handle is provided with a flow guide rib, and multiple sets of flow guide ribs are provided inside to cooperate with the manifold assembly. A damping ring is provided on the outside of the piston head, and the damping ring cooperates with the handle. The pressing plate and the handle are elastically connected by a first spring.

[0008] By adopting the above technical solution, when the sliding column moves downward to the predetermined depth, the sliding column is forced to enter the slot on the side of the locking block under the forced movement of the sliding plate, locking the sliding column and the sliding block fixed therein. At this time, since the sliding block is fixed, its lower end continuously squeezes the limiting column, keeping the limiting column in a protruding state. This protruding position corresponds to the position of the limiting locking slot opened inside the pressing plate. When the button of different gear is pressed, the length of the protruding limiting column is different, thus corresponding to different limiting locking slot depths. The operator only needs to press a button to complete the gear switching without additional tools or complicated operations, and the vibration generated during the scraping process will not automatically switch gears.

[0009] Furthermore, a guide pipe is provided at the bottom of the liquid storage tank, and the bottom of the guide pipe is connected to the oil distribution pipe through a three-way connector. A through hole that cooperates with the sliding block is opened inside the handle, and a guide plate that cooperates with the sliding plate is provided inside the handle.

[0010] By adopting the above technical solution, when the pressing plate moves downward along the inside of the handle, the limiting engagement groove on its side wall will meet the protruding limiting post in the limiting mechanism. Since the limiting post has been squeezed out by the sliding block in advance, when the pressing plate moves down to the position where the limiting engagement groove and the limiting post are aligned, the head of the limiting post will be locked into the limiting engagement groove, preventing the pressing plate from moving down further, thus determining the maximum stroke of the pressing plate. The protrusion amount of the limiting post is different in different gears, thereby realizing graded control of the liquid output.

[0011] Furthermore, the pressing plate has a limiting engagement groove that cooperates with the limiting mechanism, the pressing plate has a guide groove that cooperates with the handle, the scraping plate has a diversion groove that cooperates with the diversion manifold assembly, and the sliding plate has a through hole that cooperates with the limiting post.

[0012] By adopting the above technical solution, when the piston head moves downward, the volume inside the liquid storage tank decreases and the pressure increases. The scraping oil pre-filled in the liquid storage tank is squeezed out under pressure and first enters the guide pipe connected to the bottom of the liquid storage tank. The guide pipe transports the oil to the three-way connector, and the three-way connector then distributes the oil evenly to multiple manifold groups through the oil distribution pipe. Each manifold group has a tree-like branching structure, which further subdivides the oil into the densely distributed distribution grooves inside the scraping board. The end of the distribution groove is connected to multiple liquid outlet micro-holes on the bottom surface of the scraping board. Through multi-stage distribution, it is ensured that each liquid outlet micro-hole on the bottom surface of the entire scraping board can obtain basically equal oil pressure and flow, thereby achieving large-area synchronous liquid outlet and avoiding the uneven oil film thickness caused by traditional single-point liquid outlet.

[0013] (III) Beneficial Effects Compared with the prior art, the technical solution of the present invention has the following advantages: (1) The present invention has multiple buttons on the side of the handle, each button corresponding to a gear. After pressing, the maximum stroke of the pressing plate can be changed through the cooperation of the limiting post and the limiting locking groove. Different gears correspond to different liquid depths. For example, the low gear produces less oil and the high gear produces more oil. Users can lightly press the buttons to switch according to the actual needs of the hands, back and other parts. The operation is intuitive. At the same time, the piano key interlocking structure makes other buttons automatically pop up. The gear is not easy to jump out due to vibration during the scraping process, which improves the convenience and stability of control.

[0014] (2) When the pressing plate of the present invention is pressed down, the damping ring sleeved on the outer edge of the piston head slides in contact with the inner wall of the liquid storage tank, generating moderate frictional resistance. This resistance allows the piston head to descend at a relatively uniform speed, preventing a large amount of oil from gushing out instantly due to pressing too fast. At the same time, after the pressing plate is released, the damping ring also plays a buffering role, preventing the piston head from rebounding too fast and causing impact. Through this structure, the oil seepage rate is effectively suppressed, reducing waste and pollution, and making the oil application process during scraping more relaxed.

[0015] (3) The oil squeezed out of the storage tank of the present invention passes through the guide pipe, the three-way connector, the oil distribution pipe, the distribution manifold group and the dense distribution grooves in sequence, and finally seeps out from multiple liquid outlet micro-holes on the bottom surface of the scraping board at the same time. The multi-stage distribution structure can make each micro-hole obtain a relatively balanced oil pressure and flow rate, thereby realizing large-area synchronous liquid outlet. Compared with the traditional single-point or double-point liquid outlet method, this solution helps to form a relatively uniform oil film under the scraping working surface, reduce the dryness caused by local lack of oil, and improve the smoothness of scraping experience.

[0020] like Figures 1 to 8As shown, the present invention provides a scraping device with multi-site liquid output, including a handle 1, a pressing plate 5 inside the handle 1, a piston rod 17 at the bottom end of the pressing plate 5, a piston head 4 at the bottom end of the piston rod 17, and a limiting mechanism 8 inside the handle 1. The limiting mechanism 8 includes a button 801, a sliding block 802, a sliding column 803, a locking block 804, a sliding plate 805, a limiting post 806, a second spring 807, and a wedge block 808. The button 801 is located on the outside of the handle 1, the sliding block 802 is located at the bottom end of the button 801, the sliding column 803 is located on one side of the sliding block 802, the locking block 804 is located at the top end of the sliding plate 805, the sliding plate 805 is located inside the handle 1, the limiting post 806 is located inside the sliding plate 805, the second spring 807 is located on the outside of the limiting post 806, and the wedge block 808 is located on the sliding plate 805. At the top, a liquid storage chamber 3 is provided at the top of the piston head 4. The bottom of the liquid storage chamber 3 is connected to an oil distribution pipe 7. The top of the oil distribution pipe 7 is connected to a manifold assembly 10. A scraping board body 2 is provided at the top of the handle 1. When the operator presses a certain number key 801, the key 801 moves downward and squeezes the sliding block 802 fixed at its bottom. The sliding block 802 moves in a fixed direction under the constraint inside the handle 1. When the sliding block 802 moves downward, the sliding column 803 linked with it also moves downward synchronously. The lower end of the sliding column 803 has an inclined surface. The inclined surface slides downward along the upper inclined surface of the locking block 804 and applies pressure. The locking block 804 is fixed on the sliding plate 805. When the sliding column 803 is pressed down, it forces the sliding plate 805 to move downward. A return spring is provided behind the sliding plate 805 inside the handle 1. It is compressed and stores force to provide energy for subsequent reset.

[0021] For example, the bottom end of the handle 1 is provided with a guide rib 12, and the guide rib 12 has multiple sets of parts that cooperate with the manifold assembly 10. The piston head 4 is provided with a damping ring 14 on the outside, and the damping ring 14 cooperates with the handle 1. The pressing plate 5 and the handle 1 are elastically connected by a first spring 6. When the sliding column 803 moves downward to a predetermined depth, the sliding column 803 is forced to move by the sliding plate 805 and is just locked into the slot on the side of the locking block 804, locking the sliding column 803 and the sliding block 802 fixed thereto at that position. At this time, since the sliding block 802 is fixed, its lower end continuously presses the limiting column 806, keeping the limiting column 806 in a protruding state. This protruding position is connected to the opening inside the pressing plate 5. The positions of the limiting engagement grooves 15 are corresponding. When the buttons 801 of different gears are pressed, the lengths of the protruding limit posts 806 are different, thus corresponding to different depths of the limiting engagement grooves 15. The operator only needs to press one button 801 to complete the gear switching without additional tools or complicated operations. Moreover, the vibration generated during the scraping process will not automatically switch gears. When the operator releases the pressing plate 5, the first spring 6 (located between the pressing plate 5 and the inner wall of the handle 1) pushes the pressing plate 5 to return to its original position. At the same time, the piston rod 17 drives the piston head 4 to move upward, forming a slight negative pressure in the liquid storage chamber 3. This negative pressure stops the oil from seeping out. The damping ring 14 on the piston head 4 also provides appropriate damping during this process to prevent the piston head 4 from rebounding too quickly and causing impact. When the staff needs to reset, they need to press the fourth position button 801. When the button 801 is pressed, the sliding column 803 at its bottom moves downward. The inclined surface of the sliding column 803 presses against the wedge block 808, which in turn pushes the sliding plate 805 to move away from the locking block 804. For example, a guide pipe 13 is provided at the bottom of the liquid storage tank 3. The bottom of the guide pipe 13 is connected to the oil distribution pipe 7 through a three-way connector 9. A through hole is provided inside the handle 1 to cooperate with the sliding block 802. A guide plate is provided inside the handle 1 to cooperate with the sliding plate 805. When the pressing plate 5 moves downward along the inside of the handle 1, the limiting engagement groove 15 on its side wall will meet the protruding limiting post 806 in the limiting mechanism 8. Since the limiting post 806 has been squeezed out by the sliding block 802 in advance, when the pressing plate 5 moves down to the position where the limiting engagement groove 15 is aligned with the limiting post 806, the head of the limiting post 806 is locked into the limiting engagement groove 15, preventing the pressing plate 5 from continuing to move down, thereby determining the maximum stroke of the pressing plate 5. The protrusion of the limiting post 806 is different in different gears, thereby realizing graded control of the liquid output. For example, the pressing plate 5 has a limiting engagement groove 15 that cooperates with the limiting mechanism 8, the pressing plate 5 has a guide groove 16 that cooperates with the handle 1, the scraping plate body 2 has a diversion groove 11 that cooperates with the diversion manifold assembly 10, and the sliding plate 805 has a through hole that cooperates with the limiting post 806. The lower end of the pressing plate 5 is fixedly connected to a piston rod 17. After the piston rod 17 passes through the fixing ring 18, its lower end is fixedly connected to a piston head 4. When the pressing plate 5 is pressed down, the piston rod 17 drives the piston head 4 to move downward in the liquid storage tank 3. The outer edge of the piston head 4 is fitted with a damping ring 14. The damping ring 14 slides in contact with the inner wall of the liquid storage tank 3 to generate appropriate frictional resistance, so that the downward speed of the piston head 4 is uniform and controllable, preventing instantaneous squeezing from causing oil to spray out.

[0022] The working principle and usage process of this invention: The operator holds the handle 1 and places the scraping board 2 vertically downward (i.e., the scraping working surface faces the area to be scraped). Depending on the area to be scraped (such as the hands, back, limbs, etc.), the operator needs to switch between different liquid output levels. This device has a set of digital buttons 801 on the side of the handle 1. Each button 801 corresponds to a level: level 1 is low oil, level 2 is medium oil, level 3 is high oil, and level 4 is reset. When one button 801 is pressed, the other buttons 801 automatically pop up. When an operator presses a number key 801, key 801 moves downward and presses the sliding block 802 fixed at its bottom. The sliding block 802 moves in a fixed direction under the constraint inside the handle 1. When the sliding block 802 moves downward, the sliding column 803 linked to it also moves downward synchronously. The lower end of the sliding column 803 has an inclined surface, which slides down along the upper inclined surface of the engaging block 804 and applies pressure. The engaging block 804 is fixed on the sliding plate 805. When the sliding column 803 presses down, it forces the sliding plate 805 to move downward. A return spring located inside the handle 1 is provided behind the sliding plate 805. It is compressed and stores force to provide energy for subsequent reset. When the sliding column 803 moves downward to the predetermined depth, it is forced into the slot on the side of the locking block 804 by the sliding plate 805, locking the sliding column 803 and the sliding block 802 fixed therein in that position. At this time, since the sliding block 802 is fixed, its lower end continues to press the limiting column 806, keeping the limiting column 806 in a protruding state. This protruding position corresponds to the position of the limiting locking groove 15 opened inside the pressing plate 5. When the button 801 of different gears is pressed, the length of the protruding limiting column 806 is different, thus corresponding to different depths of the limiting locking groove 15. The operator only needs to press one button 801 to complete the gear switching without additional tools or complicated operations, and the vibration generated during the scraping process will not automatically switch gears. After setting the gear, the staff member holds the handle 1 and places the bottom surface of the scraping board body 2 against the skin of the area to be scraped. At this time, the staff member presses the pressure plate 5 at the top of the handle 1 with their thumb. When the pressing plate 5 moves downward along the inside of the handle 1, the limiting engagement groove 15 on its side wall will meet the protruding limiting post 806 in the limiting mechanism 8. Since the limiting post 806 has been pre-pressed and protruded by the sliding block 802, when the pressing plate 5 moves down to the position where the limiting engagement groove 15 and the limiting post 806 are aligned, the head of the limiting post 806 gets into the limiting engagement groove 15, preventing the pressing plate 5 from moving further down, thus determining the maximum stroke of the pressing plate 5. The protrusion amount of the limiting post 806 is different in different gears, thereby realizing graded control of the liquid output. A piston rod 17 is fixedly connected to the lower end of the pressing plate 5. After the piston rod 17 passes through the fixing ring 18, a piston head 4 is fixedly connected to its lower end. When the pressing plate 5 is pressed down, the piston rod 17 drives the piston head 4 to move downward in the liquid storage tank 3. A damping ring 14 is sleeved on the outer edge of the piston head 4. The damping ring 14 slides in contact with the inner wall of the liquid storage tank 3 to generate appropriate frictional resistance, so that the downward speed of the piston head 4 is uniform and controllable, and prevents the oil from gushing out due to instantaneous squeezing. When the piston head 4 moves downward, the volume inside the liquid storage tank 3 decreases and the pressure increases. The scraping oil pre-filled in the liquid storage tank 3 is squeezed out under pressure and first enters the guide pipe 13 connected to the bottom of the liquid storage tank 3. The guide pipe 13 transports the oil to the three-way connector 9. The three-way connector 9 then distributes the oil evenly to multiple manifold groups 10 through the oil distribution pipe 7. Each manifold group 10 has a tree-like branching structure, which further subdivides the oil into the densely distributed distribution grooves 11 inside the scraping plate body 2. The end of the distribution groove 11 is connected to multiple liquid outlet micro-holes on the bottom surface of the scraping plate body 2. Through multi-stage distribution, it is ensured that each liquid outlet micro-hole on the bottom surface of the entire scraping plate body 2 can obtain basically equal oil pressure and flow rate, thereby achieving large-area synchronous liquid outlet and avoiding the uneven oil film thickness caused by traditional single-point liquid outlet. At this time, the staff moved the scraping board 2 to perform scraping operation. Since the oil film always exists between the bottom surface of the scraping board 2 and the skin, the frictional resistance is significantly reduced, and the scraping process is smooth and without dryness. When the operator releases the pressing plate 5, the first spring 6 (located between the pressing plate 5 and the inner wall of the handle 1) pushes the pressing plate 5 to return to its original position. At the same time, the piston rod 17 drives the piston head 4 to move upward, and a slight negative pressure is formed in the liquid storage tank 3. This negative pressure causes the oil to stop seeping out. The damping ring 14 on the piston head 4 also provides appropriate damping during this process to prevent the piston head 4 from rebounding too quickly and causing an impact. When the staff needs to reset, they need to press the fourth position button 801. When the button 801 is pressed, the sliding column 803 at its bottom moves downward. The inclined surface of the sliding column 803 presses against the wedge block 808, which in turn pushes the sliding plate 805 to move away from the locking block 804. This causes the sliding block 802 to no longer be locked, and under the stored elastic force of the second spring 807, it slides upward to reset. After the sliding block 802 moves upward, the squeezing force on the limiting post 806 disappears.
