Description

Technical Field

[0001] This utility model relates to the field of physiotherapy instruments, and in particular to a waterproof scraping instrument. Background Technology

[0002] Gua sha and cupping are based on the theory of meridians and acupoints in traditional Chinese medicine. Through a specially made gua sha and cupping device and corresponding techniques, a certain medium is applied to the skin and repeatedly scraped and rubbed. This causes the skin to show red millet-like or dark red bleeding points, which are called "sha" changes. This achieves the effect of promoting blood circulation and removing sha. It is a very common treatment method in traditional Chinese medicine. It stimulates muscle tissue contraction, accelerates blood flow, and promotes the body's metabolism.

[0003] Currently, there are gua sha devices on the market that are more convenient to use than traditional gua sha equipment. However, existing gua sha therapy devices require the user to apply liniment during operation, which can easily cause the liniment to enter the device through gaps such as the charging port or the connection between the cover and the device, causing damage to the internal electronic components. In addition, the air outlet on existing gua sha devices is usually located on the side wall of the main body. When the user holds the gua sha device and pushes it, it is easy to block the air outlet with their hand, which prevents the internal air from escaping, resulting in excessive internal air pressure and affecting the adsorption effect of the gua sha device.

[0020] like Figures 1 to 4As shown, this utility model provides a waterproof scraping device, including a body, which includes a main body 1 and a tank 2 located at the bottom of the main body 1; specifically, the main body 1 is provided with an electronic control unit and an air pump unit electrically connected to the electronic control unit, and the side wall of the tank 2 is provided with an exhaust unit for exhausting air, and the exhaust unit and the air pump unit are connected by a pipe structure.

[0021] The machine has an internal waterproof structure. This waterproof structure can take many forms depending on existing waterproofing systems on the market, such as applying a waterproof layer to the inner wall or adding a sealing structure; any method that provides waterproofing is acceptable. Most products on the market currently lack a waterproof structure. However, it needs to be used with essential oils during scraping and cupping to prevent skin abrasions. After use, the machine will be quite dirty and requires rinsing or soaking in water to remove residual oil. If the product is not properly waterproofed, water may leak into the machine during cleaning, causing damage.

[0022] The exhaust unit includes an exhaust component 3 fixedly installed on the bottom surface of the tank body 2. The exhaust component 3 is L-shaped and has an exhaust channel 4 inside. Specifically, the two ends of the exhaust channel 4 are a first exhaust port 5 and a second exhaust port 6, respectively. The first exhaust port 5 is arranged on the side wall of the tank body 2 and connects to the outside and the exhaust channel 4. The second exhaust port 6 is arranged inside the tank body 2.

[0023] The advantages of arranging the first air outlet 5 on the side wall of the tank body 2 are: 1. When using the product, the user needs to hold the machine body. If the first air outlet 5 is placed on the main body 1, the user will block the first air outlet 5 with their hand during the pushing and using process, which will prevent the air from being expelled. This will result in excessive internal air pressure, which will prevent air from entering and affect the adsorption effect of the scraping device. Furthermore, placing the first air outlet 5 on the can body 2 can effectively prevent the pressure difference between the inside and outside, resulting in better waterproof performance. 2. The air pump 10 is fixed on the bracket 7. If the air outlet 3 is arranged on the main body 1, the air outlet pipe needs to be connected to the exhaust port during the production process, which is more troublesome. On the contrary, if the air outlet 3 is arranged on the tank 2, the air outlet pipe can be easily connected, simplifying the installation of the air outlet pipe. 3. Placing the first air outlet 5 on the side of the tank body 2 will not affect the overall appearance, because the tank body 2 is located at the bottom of the main body 1.

[0024] The upper part of the tank body 2 is provided with a bracket 7 for installing the electrical control unit and the air pump unit. The bracket 7 is provided with a through hole 8 for the pipe structure to pass through. The through hole 8 is arranged above the second air outlet 6. Specifically, one end of the pipe structure is connected to the air pump unit, and the other end of the pipe structure is connected to the second air outlet 6 through the through hole 8.

[0025] The electronic control unit includes a battery 9, and the air pump unit includes an air pump 10 or a solenoid valve, preferably an air pump 10; specifically, the pipe structure includes an air outlet pipe, and the bracket 7 is provided with at least two mounting brackets 11 for mounting and fixing the battery 9 and the air pump 10.

[0026] The bottom surface of the inner side of the tank 2 is fixedly provided with a ring-shaped computer board 12 with heating function, and the computer board 12 and the battery 9 are electrically connected; specifically, a number of steel balls 13 for scraping are rotatably connected to the bottom of the tank 2. One end of the steel ball 13 is inserted into the computer board 12, and the other end of the steel ball 13 protrudes from the outside of the tank 2. The steel balls 13 are evenly spaced around the computer board 12.

[0027] The bracket 7 is provided with an air inlet 14 near the middle, which communicates with the outside. The air inlet 14 contains an air inlet chamber 15. Specifically, the bottom of the tank body 2 is provided with an air inlet 16 that communicates with the outside air and the air inlet chamber 15. The air inlet 14 is connected to the air pump unit. The air pump unit works by introducing air into the machine body through the air inlet 14.

[0028] Existing products on the market introduce air through a tank 2 at the bottom of the machine body, with an air intake component 14 as described in this invention. Exhaust is directly discharged into the machine body. Because existing products are not completely sealed, they are in a permeable state. If the product were waterproof and sealed, it would affect the exhaust of the internal air pump 10. If the exhaust cannot be discharged, the internal air pressure will be too high, preventing air intake and thus losing the negative pressure scraping and cupping function. Therefore, this invention designs an external exhaust component 3. In addition, even if internal exhaust is possible in existing technologies, it is impossible to achieve the effect of turning on the machine while submerged in water. If this were the case, water would be directly sucked into the machine body, causing water damage. With the external exhaust component 3, this invention allows the product to work normally even if the user accidentally touches the power button during cleaning, expelling the sucked-in water through the first air outlet 5, ensuring that the product will not be damaged in any cleaning environment.

[0029] The top of the main body 1 extends outward to provide a handle 17 for easy gripping by the user; the side of the main body 1 is provided with a switch 18 that is electrically connected to both the electronic control unit and the air pump unit.

[0030] The working principle of this utility model is as follows: Press the switch 18 to start, the battery 9 supplies power to the air pump 10 and the computer board 12, the computer board 12 starts to work and generates heat, the heat is conducted to the skin of the person being scraped through the steel ball 13 plugged into the computer board 12, optimizes the scraping effect, and can improve the user experience of the person being scraped. Simultaneously, the air pump 10 starts working, delivering outside air sequentially through the air inlet 16 and air inlet chamber 15 of the air inlet component 14 into the machine body. Then, the air pump 10 delivers the air inside the machine body to the air outlet component 3 through the air outlet pipe. The air passes through the second air outlet 6 and the air outlet channel 4, and finally exits to the outside through the first air outlet 5. This draws out the air between the gua sha device and the skin, creating an environment below atmospheric pressure, forming negative pressure. Under the action of negative pressure, the skin is tightly adhered to the gua sha device. This suction can promote skin flushing or bruising, helping to expel toxins from the body and prevent diseases. The generation of negative pressure not only ensures a close fit between the gua sha device and the skin, but also promotes blood circulation and accelerates lymphatic fluid flow, thereby achieving the effects of promoting blood circulation, removing blood stasis, and relieving pain. In addition, to optimize the scraping effect, it is necessary to apply liniment or essential oil to the user's body. During the scraping process, sweat will appear on the skin surface. Since the machine has a waterproof structure inside, it can effectively prevent short circuits caused by liquid entering the machine.

[0031] The advantages of this invention are as follows: By setting a waterproof structure inside the machine body, the entire machine is waterproofed, preventing liniment, essential oils, and sweat from entering the machine body and damaging the internal electronic components; by arranging the first air outlet 5 on the side wall of the can body 2, it prevents the user from blocking the first air outlet 5 with their hand during use, which would cause excessive internal air pressure and affect the adsorption effect of the scraping device; and by placing the first air outlet 5 on the can body 2, it effectively prevents the pressure difference between the inside and outside, resulting in a better waterproof effect.
