Description

Technical Field

[0001] This utility model relates to the field of massage therapy technology, and in particular to a magnetic pressure relief scraping device. Background Technology

[0002] Currently, electronic gua sha devices are available on the market. These devices use an air suction device to draw air from the device, creating negative pressure inside. This allows the magnetically suctioned gua sha device to adhere to specific areas of the body, achieving a cupping effect. However, since the negative pressure is created by controlling a solenoid valve, the most direct way to release pressure is to pull the magnetically suctioned gua sha device off the skin, allowing the air inside the negative pressure chamber to come into contact with the outside air, thus releasing the pressure. This method is cumbersome and can cause pain to the skin. While existing technologies use pressure relief valves to control pressure release, this method is simple, but if the valve is damaged, it will not achieve the desired effect and is more expensive. Therefore, the traditional method of pulling the gua sha device off the skin remains the only viable option for pressure release. Utility Model Content

[0021] Figure 7 This is a cross-sectional view of Embodiment 2 of this utility model. Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0023] Example 1, as Figure 1-4 As shown, a magnetic pressure relief scraping device includes a handle 1, a negative pressure air pump inside the handle 1, a scraping head 2 at the lower end of the handle 1, a negative pressure air nozzle 3 inside the scraping head 2 for use with the negative pressure air pump, an air hole 4 on the outer edge of the negative pressure air nozzle 3, and a magnetic pressure relief device 5 inside the scraping head 2. The magnetic pressure relief device 5 includes a magnetically movable part 6, and a magnetically attached component 7 corresponding to the air hole 4 is provided at the inner end of the magnetically movable part 6. In use, the magnetic pressure relief device 5 and the air hole 4 are manually controlled to extend and retract to achieve the effect of pressure relief and negative pressure. The structure is simple, the pressure relief operation is convenient, and it can effectively reduce costs.

[0024] In this embodiment, the magnetic suction assembly 7 includes a magnet 71 disposed at the inner end of the magnetic suction movable plate. A steel ball 72, which cooperates with the air hole 4, is connected to the inner end of the magnet 71. A limiting connecting frame 73 is provided on one side of the scraping head 2 corresponding to the magnetic suction movable component 6. The limiting connecting frame 73 prevents excessive pressing by the pressing plate 63. A movable connecting hole is provided on the limiting connecting frame 73. The magnetic suction movable component 6 includes a movable sleeve rod 61, one end of which is inserted into the movable connecting hole. The magnet 71 is disposed at the other end of the movable sleeve rod 61. A spring 62 is provided between the movable sleeve rod 61 and the limiting connecting frame 73. The movable sleeve 61 is connected to the magnet 71 at one end and is also provided with a pressing plate 63. One end of the pressing plate 63 is sleeved outside the negative pressure air nozzle 3, and the other end extends outside the scraping head 2. The movable sleeve 61 has a T-shaped cross section. In actual use, by pressing the pressing plate 63, the movable sleeve 61 moves backward, which at the same time drives the magnet and the steel ball 72 to move, so that the steel ball 72 and the air hole 4 are separated, thereby releasing pressure. After releasing the pressing plate 63, under the action of the spring 62, the movable sleeve 61, the pressing plate 63, the magnet 71 and the steel ball 72 return to their original positions, so that the steel ball 72 blocks the air hole 4 and forms a sealed negative pressure.

[0025] In this embodiment, the end of the air hole 4 relative to the magnet 71 is provided with a connecting ring 64 to facilitate the movement of the steel ball 72 within it. A steel ball tunnel 68 is formed inside the connecting ring 64. An arc-shaped contact surface 65 is formed between the connecting ring 64 and the outer opening of the air hole 4 to facilitate contact with the steel ball 72. When the pressing plate 63 is pressed down, causing the movable sleeve rod 61 to move backward and simultaneously moving the magnet, the steel ball 72 will retreat in the steel ball tunnel 68, causing a gap between the arc surface of the steel ball 72 and the arc-shaped contact surface 65 of the air hole 4, thereby generating pressure relief. Due to the direct contact between the steel ball 72 and the magnet 71, the force of the spring 62 tightly contacts the arc surface of the steel ball 72 with the arc-shaped contact surface 65 of the air hole 4, forming a sealing negative pressure.

[0026] In this embodiment, a sealing ring 66 is provided inside the air hole 4, and a sealing ring pressure block 67 for limiting the sealing ring 66 is provided between the movable sleeve rod 61 and the air hole 4. The sealing ring pressure block 67 forms the steel ball tunnel 68. In addition to sealing the air hole 4 with the steel ball 72 through the arc surface of the steel ball 72 and the arc-shaped contact surface 65 of the air hole 4, it can also be sealed by the sealing ring 66 to improve the sealing effect. The sealing ring 66 can be fixed inside the air hole 4 by the sealing ring pressure block 67.

[0027] In this embodiment, the movable sleeve 61, pressing plate 63, magnet 71, and steel ball 72 are injection molded into an integral structure. During processing, the magnet 71 is placed in the hole of the T-shaped movable sleeve 61, and then the movable sleeve 61, pressing plate 63, and magnet 71 are integrally injection molded. Alternatively, the magnet 71, steel ball 72, movable sleeve 61, and pressing plate 63 can all be directly injection molded from plastic material to form an integral plastic part. One end of this plastic part has the same arc surface as the steel ball 72, which facilitates its use with the air hole 4 or sealing ring 66.

[0028] Example 2, as Figure 5-7 As shown, the difference between this embodiment and Embodiment 1 is that one end of the movable sleeve 61 connected to the magnet 71 is also provided with a toggle switch plate 610 that is axially connected to the scraping head 2 via a connecting shaft 611. One end of the toggle switch plate 610 extends out of the scraping head 2. By toggling the toggle switch plate 610 clockwise, it rotates around the connecting shaft 611, and at the same time, the movable sleeve 61 moves backward, driving the magnet and the steel ball 72 to move, so that the steel ball 72 and the air hole 4 are separated, thereby releasing pressure. After releasing the toggle switch plate 610, under the action of the spring 62, the movable sleeve 61, the pressing plate 63, the magnet 71 and the steel ball 72 return to their original positions, so that the steel ball 72 blocks the air hole 4, forming a sealed negative pressure.

[0029] In this embodiment, the movable sleeve 61, the toggle switch plate 610, the magnet 71, and the steel ball 72 are injection molded into an integral structure. During processing, the magnet 71 is placed in the hole of the T-shaped movable sleeve 61, and then the movable sleeve 61, the toggle switch plate 610, and the magnet 71 are integrally injection molded. Alternatively, the magnet 71, the steel ball 72, the movable sleeve 61, and the toggle switch plate 610 can all be directly injection molded from plastic material to form an integral plastic part. One end of this plastic part has the same arc surface as the steel ball 72, which facilitates its use with the air hole 4 or the sealing ring 66.

[0030] In this embodiment, the limiting connecting frame 73 includes a limiting rear frame plate 612 connected to the scraping head 2 corresponding to the outer end of the movable sleeve rod 61. The movable connecting hole is provided on the rear frame plate. The spring 62 is provided between the limiting rear frame plate 612 and the movable sleeve rod 61. A limiting side frame plate 613 is provided on the inner side of the movable sleeve rod 61. The movable connecting hole facilitates the movement of the movable sleeve rod 61, while the limiting side frame plate 613 is provided with a limiting hole, which facilitates the rotation of the toggle switch plate 610 to control the transition movement of the movable sleeve rod 61.

[0031] Based on the concept of this utility model, there may be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model.
