Description

Technical Field

[0001] This utility model relates to traditional Chinese medicine health care and treatment instruments, and in particular to a vacuum cupping device adapted to a cupping and scraping instrument. Background Technology

[0002] Traditional vacuum cupping devices typically consist of a cupping jar, a one-way valve, and an external vacuuming tool (such as a manual air pump or an electric negative pressure device). The one-way valve on the surface of the cupping jar needs to be precisely aligned with the vacuuming tool to achieve negative pressure adsorption. This design has significant limitations in practical applications: the alignment process between the one-way valve and the vacuuming tool requires the user to repeatedly adjust the angle and position, which is cumbersome, especially when used in blind spots such as behind the user. In addition, traditional one-way valves have a small diameter, which limits the air extraction rate, and after long-term use, the valve body is prone to leakage due to wear or blockage by foreign objects, affecting the stability of the negative pressure. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a vacuum cupping device that is compatible with cupping and scraping instruments.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vacuum cupping device adapted to a cupping and scraping instrument, comprising: a cup body, the open end of which is used to fit against the human body surface; an insertion part, disposed on the top of the cup body away from the open end, the insertion part being a large-diameter cylindrical boss structure, the outer diameter of which matches the inner diameter of the circular groove of the cupping and scraping instrument to form a clearance fit, the insertion part having a suction channel communicating with the inner cavity of the cup body through the central axis; a sealing part, disposed on the outer circumferential surface of the insertion part or the inner wall of the circular groove, used to form a sealed cylindrical cavity between the insertion part and the circular groove during insertion; the bottom of the circular groove having an air extraction hole communicating with the negative pressure system of the cupping and scraping instrument, the air extraction hole performing a vacuum operation on the inner cavity of the cup body through the cylindrical cavity and the suction channel to generate negative pressure adsorption.

[0005] As a preferred technical solution of this utility model, the insertion direction of the plug and the circular groove is consistent with the axial direction of the jar body, and the adsorption and release of the jar body are directly controlled by the negative pressure system of the cupping and scraping instrument.

[0006] As a preferred embodiment of the present invention, the sealing part includes at least one annular sealing groove distributed axially along the outer peripheral wall of the insertion part, and an elastic sealing ring embedded in the annular sealing groove.

[0007] As a preferred embodiment of the present invention, the sealing part includes at least one annular rib integrally formed on the outer wall of the insertion part.

[0008] As a preferred technical solution of this utility model, the top of the tank is provided with a molding structure, including a plurality of arc-shaped plates distributed along the circumferential direction, and the bottom of the insertion part is provided with a molding groove corresponding to the arc-shaped plates.

[0009] As a preferred technical solution of this utility model, a one-way valve is detachably installed in the air intake channel of the plug part, and the airflow direction of the one-way valve is unidirectional from the tank body to the circular groove.

[0010] As a preferred embodiment of this utility model, the edge of the opening end of the tank is folded outward to form a flexible sealing lip.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the insertion part of the large-diameter cylindrical boss structure is directly inserted into the circular groove of the cupping and scraping instrument, eliminating the alignment step of the traditional one-way valve and realizing "plug and play". It is especially suitable for operation in blind areas such as the back, greatly simplifying the process; the air intake channel through the center of the insertion part and the air extraction hole of the circular groove form an efficient negative pressure path, which, combined with the large-diameter design, significantly improves the air extraction rate and shortens the adsorption time.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figure 1-7 A vacuum cupping device adapted to a cupping and scraping instrument is shown, comprising: a cup body 1, the open end of which is used to fit against the human body surface; a plug part 2, disposed on the top of the cup body 1 away from the open end, the plug part 2 being a large-diameter cylindrical boss structure, the outer diameter of which matches the inner diameter of the circular groove 15 of the cupping and scraping instrument 14 to form a clearance fit, and an air intake channel 3 communicating with the inner cavity of the cup body 1 being provided through the central axis of the plug part 2; a sealing part 4, disposed on the outer peripheral surface of the plug part 2 or the inner wall of the circular groove 15, used to form a sealed cylindrical cavity 5 between the plug part 2 and the circular groove 15 during insertion; and an air extraction hole 6 at the bottom of the circular groove 15 communicating with the negative pressure system of the cupping and scraping instrument 14, the air extraction hole 6 performing a vacuum operation on the inner cavity of the cup body 1 through the cylindrical cavity 5 and the air intake channel 3 to generate negative pressure adsorption.

[0023] The insertion part 2 with a large-diameter cylindrical boss structure is directly inserted into the circular groove 15 of the cupping and scraping instrument 14, eliminating the alignment step of the traditional one-way valve 12 and realizing "plug and play". It is especially suitable for operation in blind areas such as the back, greatly simplifying the process. The air intake channel 3 through the center of the insertion part 2 and the air extraction hole 6 of the circular groove 15 form a high-efficiency negative pressure path. Combined with the large-diameter design, it significantly improves the air extraction rate and shortens the adsorption time.

[0024] The insertion direction of the plug part 2 and the circular groove 15 is consistent with the axial direction of the jar body 1. The suction and release of the jar body 1 are directly controlled by the negative pressure system of the cupping and scraping instrument 14. The design of the insertion direction being consistent with the axial direction of the jar body 1 is ergonomic and reduces the risk of misoperation.

[0025] like Figure 2 , 3 As shown, the sealing part 4 includes at least one annular sealing groove 7 axially distributed along the outer peripheral wall of the insertion part 2, and an elastic sealing ring 8 embedded in the annular sealing groove 7; or, as Figure 4 , 5As shown, the sealing part 4 includes at least one annular rib 9 integrally formed on the outer wall of the insertion part 2. The insertion part 2 and the circular groove 15 are fitted with a clearance. The combination of the annular sealing groove 7 and the elastic sealing ring 8 (or the integral annular rib 9) forms a multi-seal structure to ensure the airtightness of the cylindrical cavity 5 and avoid negative pressure attenuation caused by air leakage.

[0026] like Figure 6 , 7 As shown, the top of the tank 1 is provided with a molding structure, including several arc-shaped clamping plates 10 distributed along the circumference. The bottom of the insertion part 2 is provided with a molding groove 11 for the arc-shaped clamping plates 10 to be inserted. In this embodiment, the preferred method is that the insertion part 2 is directly molded on the arc-shaped clamping plate 10. The insertion part 2 is made of soft rubber material, specifically rubber or silicone, etc.; or it is a split structure. In this way, the standardized size design of the insertion part 2 can be adapted to the circular groove 15 of various models of instruments, and the molding structure (such as the arc-shaped clamping plate 10 and the molding groove 11) facilitates quick disassembly and maintenance, and extends the life of the device.

[0027] A one-way valve 12 is detachably installed in the air intake channel 3 of the plug part 2. The airflow direction of the one-way valve 12 is unidirectional from the tank body 1 to the circular groove 15. In this embodiment, the one-way valve 12 is commercially available, which is prior art, so it is not described in detail.

[0028] The edge of the opening end of the can 1 is folded outward to form a flexible sealing lip 13. The flexible sealing lip 13 folded outward at the opening end of the can 1 further conforms to human skin, preventing air leakage at the edge and improving the comfort of use.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
