[0023] Please refer to Figures 1-4 A microcrystalline skin grinding instrument for enhancing negative pressure comprises:

[0024] The skin grinding rod main body 1 is provided with a negative pressure connection air nozzle 2 for being connected with a main machine on one side, and is provided with a skin grinding head 3 for contacting and working on skin on the other side;

[0026] The inner cavity of the piston limiting piece 6 is provided with a second sealing ring 11 for sealing the gap between the piston connecting piece 7 and the surrounding components, the side of the second sealing ring 11 is provided with a pressing sheet 12, the pressing sheet 12, the gasket 4 and the piston limiting piece 6 jointly form a valve body structure of on-off switch under different pressures, the inner cavity of the piston connecting piece 7 is provided with a channel 13 for allowing gas to flow, and the channel 13 is distributed in a plurality of circumferential arrays.

[0027] The negative pressure connection air nozzle 2 is designed to be asymmetric in thickness, the thicker end of the negative pressure connection air nozzle 2 is fixedly connected with the skin grinding rod main body 1, and the thinner end of the negative pressure connection air nozzle 2 is connected with a negative pressure pump of the main machine.

[0028] In the embodiment of the utility model, when the skin polishing head 3 does not contact the skin, the valve body is in the closed state under the extrusion of the second sealing ring 11, and the gas cannot flow, and when the skin polishing head 3 contacts the skin, the pressure of the skin on the skin polishing head 3 is transmitted to the second sealing ring 11 through the piston limiting piece 6, so that the second sealing ring 11 is deformed, and then the piston limiting piece 6 is moved, the gap between the piston limiting piece 6 and the sealing gasket 4 is enlarged, and the gas is allowed to flow. Embodiment

[0029] Please refer to Figures 1-5 In order to further optimize the user experience, a cavity is added to the gas suction end. The cavity is independent of the structure of the negative pressure pump and the skin polishing rod main body 1, and is communicated in the overall gas path. When the negative pressure pump works, the cavity can store a certain amount of gas, and rapidly release under the action of negative pressure, thereby accelerating the response speed of the negative pressure system and improving the use efficiency; the design of the cavity can realize higher gas flow under the same negative pressure condition. Preferably, a manual check valve is added in the gas flow path, in the working state, the check valve is opened, the negative pressure directly acts on the skin, and the skin polishing effect is improved; and in the non-working state, the check valve is automatically closed, avoiding the rapid reduction of the negative pressure in the cavity. This design not only ensures that the system can maintain a negative pressure environment, but also enables the user to more flexibly control the negative pressure in different working states, and optimizes the convenience and comfort of use. In order to realize the protection of the cavity and the negative pressure pump, a corresponding case can be configured, without changing the communication of the gas path, the negative pressure pump and the cavity are put into the inner cavity of the case to realize the protection function.

[0030] In use, the skin polishing rod main body 1 is the core component of the whole device, one end of which is connected with the negative pressure pump of the host through the negative pressure connection air nozzle 2, and the other end is provided with the skin polishing head 3 for contacting the skin for work. The skin polishing head 3 is threadedly connected with the piston connecting piece 7 through the skin polishing head connecting piece 9, which ensures the stable installation of the skin polishing head 3, and the setting of the first sealing ring 10 effectively prevents the gap leakage of the skin polishing head 3 after installation and the surrounding components, and ensures the sealing property of the negative pressure system.

[0031] Inside the main body 1 of the dermabrasion rod, the piston limiting piece 6, the second sealing ring 11, the pressing plate 12 and the sealing gasket 4 jointly constitute a controllable valve body structure. When the dermabrasion head 3 does not contact the skin, the valve body is in a closed state under the extrusion of the second sealing ring 11, and the gas cannot flow; when the dermabrasion head 3 contacts the skin, the pressure of the skin on the dermabrasion head 3 is transmitted to the second sealing ring 11 through the piston limiting piece 6, so that the second sealing ring 11 is deformed, and then the piston limiting piece 6 is moved, the gap between the piston limiting piece 6 and the sealing gasket 4 is enlarged, and the gas is allowed to flow. This design ensures that the dermabrasion head 3 can quickly respond when working, opens the negative pressure channel, and realizes the negative pressure acting on the skin surface.

[0032] A cavity is added to the gas suction end of the negative pressure pump, which not only improves the flow rate, but also enhances the maintenance ability of the negative pressure system. In the non-working state, the cavity can store a certain amount of negative pressure gas, avoiding the rapid reduction of the negative pressure value. Therefore, when the user uses the dermabrasion head 3 again, the system can quickly respond and provide a stable negative pressure environment again, ensuring the persistence of the cleaning effect.

[0033] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits, and the scope of the utility model is defined by the appended claims and their equivalents.
