Description

Technical Field

[0001] This utility model relates to the field of health care equipment technology, specifically to an electric cupping device with interchangeable nozzles. Background Technology

[0002] Cupping, as a traditional Chinese culture and technique, has become increasingly popular throughout the country. Traditional cupping uses a fire cupping method, where alcohol burns inside the cup, causing the gas inside to contract and thus attracting the cup. However, this method has many limitations in current use. The most prominent one is that the open flame poses a significant safety hazard when used by non-professionals, making it difficult to popularize for home use.

[0003] In response to this, utility model patent CN217697448U discloses a constant-pressure electric cupping device capable of injecting medication, belonging to the field of health care equipment. It includes a housing. A cup body is provided on the lower surface of the housing, and a partition is fixedly connected to the inner wall of the housing. A sealing chamber is fixedly connected to the lower surface of the partition. When the pump is turned off, its pressure spring keeps the sealing plug in a rapid reset and sealing state, and then the entire device is removed. Simply keep the airtight cover detached from the housing surface, and the sealing plug will maintain a seal under the negative pressure inside the cup body. This method ensures good airflow extraction and rapid reset during use. Simultaneously, when the internal extraction pressure is too high, the pressure spring can limit the minimum pressure inside the cup body; when the pressure is too low, the sealing bead is pressured, pressing the pressure spring, and resets after the pressure is appropriate. This effectively prevents excessive extraction by non-professional users from causing excessive skin damage. It greatly facilitates widespread home use by non-professionals.

[0004] However, the cupping device in the aforementioned patent application still has some problems: When using the current cupping device, due to different cupping locations, the person needs to use cups of different diameters for cupping operations. It is difficult to adjust the diameter of the cups, which requires the person to frequently change different cups, which is not conducive to the person's use. Utility Model Content

A movable rod 207 is rotatably connected inside each rotating seat 206.

[0028] The negative pressure mechanism 1 includes a housing 101. A negative pressure pump 108 is installed in the middle of the inner wall of the housing 101. The air inlet of the negative pressure pump 108 is fixedly connected to a suction pipe 109, and the bottom end of the suction pipe 109 is fixedly connected to a docking cap 110. Limiting protrusions 111 are fixedly provided on both sides of the inner wall of the housing 101. An exhaust pipe 112 is fixedly connected to the air outlet of the negative pressure pump 108. A fixing plate is fixedly provided at the bottom of the inner wall of the housing 101. A fixing hole opened in the middle of the bottom end of the fixing plate is fixedly connected to the outer wall of the docking cap 110. An arc-shaped mesh is threadedly connected to the top of the inner wall of the housing 101.

In the auxiliary cup assembly 208, the user rotates the threaded ring 2081, thereby separating it from the auxiliary cup 2082, leaving a suitable diameter auxiliary cup 2082. At this time, the negative pressure pump 108 is started through the negative pressure switch 105. The battery 107 in the handle 103 supplies power to the negative pressure pump 108. The negative pressure pump 108 operates through the suction pipe 109 and the docking... When the cap 110 is engaged, air can be drawn out of the main tank 201 through the docking sleeve 202, thereby creating negative pressure. Then, the handle 103 can be rotated to separate the limiting protrusion 111 in the housing 101 from the limiting member 204 on the docking sleeve 202, and the docking cap 110 separates from the docking sleeve 202. The venting valve 203 in the docking sleeve 202 can ensure that the main tank 201 is sealed. After the cupping is completed, the person can press the venting valve 203 to connect the main tank 201 with the outside, so that the person can easily remove the cupping mechanism 2.
