[0025] The utility model is further described below in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, a scraping device designed based on the principle of negative pressure suction includes a device cover 1, a manual pressing scraping module, an external shell 3, and a scraping end component that contacts the human body. The overall material of the scraping device is medical-grade ABS material. The overall material selection is mainly based on safety and meets the biocompatibility requirements of medical equipment, taking into account its lightweight, easy processing, and aesthetics.

[0027] The outer shell 3 is a cylindrical structure with an open top, and the central cavity of the outer shell 3 is cylindrical. The upper half of the outer shell 3 is provided with manual pressing handle sliding grooves from top to bottom along the radially symmetrical left and right sides.

[0028] The manual pressing scraping module includes a cylindrical slide bar and manual pressing handles arranged on both sides of the top of the cylindrical slide bar. The cylindrical slide bar is inserted into the central cavity of the external shell 3, and the two manual pressing handles are respectively placed in two manual pressing handle sliding grooves in a one-to-one correspondence. Manual pressing can drive the two manual pressing handles to slide up and down in the manual pressing handle sliding grooves, thereby driving the cylindrical slide bar to slide up and down in the central cavity.

[0029] Two first O-ring installation grooves are arranged in parallel at the bottom of the cylindrical slide rod, and a first O-ring is installed in each of the two first O-ring installation grooves. The outer diameter of the first O-ring is larger than the diameter of the central cavity, so that the first O-ring is inserted into the central cavity with an interference fit and can slide and seal with the cylindrical slide rod moving up and down. In this embodiment, the first O-ring is a 21×3.1 O-ring.

[0030] The cylindrical slide rod has an axial opening in the center, and an air inlet pipe of a first duckbill one-way valve is inserted into the top of the hole. The air outlet pipe of the first duckbill one-way valve is inserted into the one-way valve fixing piece, and the one-way valve fixing piece is fixed to the top of the cylindrical slide rod by an M2×5 hexagon socket flat round head screw 10.

[0031] The equipment cover 1 is fixed to the top of the external housing 3 by using M2×6 hexagon socket flat head set screws 9.

[0032] The scraping terminal assembly includes a terminal shell 4, the bottom surface of which is concave to form a scraping cavity in contact with the human body, the terminal shell 4 has an axial opening in the center, the air inlet pipe of the second duckbill one-way valve is inserted in the top of the hole, the air outlet pipe of the second duckbill one-way valve is inserted in the central through hole at the bottom of the external shell 3, the top of the terminal shell 4 is fixedly connected to the bottom of the external shell 3, and a second O-ring is provided at the connection. Specifically, an annular ring protrudes from the bottom of the external shell 3, and an annular groove is provided at the top of the terminal shell 4. The annular ring at the bottom of the external shell 3 is inserted into the annular groove at the top of the terminal shell 4, and is locked and fixed by an M2×6 hexagon socket countersunk screw 11. In this embodiment, the second O-ring is selected from a 12×2 O-ring.

[0033] The scraping device designed based on the negative pressure suction principle described in this embodiment adopts the design of the negative pressure suction principle. Inside the external shell, there are two first O-rings with interference fit between the manual pressing assembly and the terminal shell. By stretching the manual pressing assembly upward, a negative pressure environment is formed inside the external shell due to the presence of the duckbill-shaped one-way valve, which generates suction on the surface skin in contact with the human body. At the connection between the external shell and the terminal shell, due to the presence of the duckbill-shaped one-way valve and the second O-ring, the sealing performance of this position is good.
