Description

Technical Field

[0001] This utility model relates to the field of cupping technology, and in particular to a self-contained cupping device for the waist and back. Background Technology

[0002] Traditional cupping devices typically use bamboo or glass jars. When used, a lit alcohol-soaked cotton ball is placed inside the jar to raise the air temperature and reduce its density. The jar is then quickly placed over an acupoint on the body. The reduced temperature inside the jar creates negative pressure, drawing the skin in. Because using an open flame poses a risk, some modern products employ a negative pressure structure. This works by creating a sealed chamber between the jar and the limb, using a piston or air pump to draw air out of the jar, creating a negative pressure environment inside. For example, patent CN219208361U discloses an electric cupping device.

[0003] However, the existing negative pressure cupping structure cannot be used to treat the lower back area alone, which greatly limits its use. Utility Model Content

[0004] This invention provides a self-contained cupping device for the lower back, which helps to solve the problem that some current negative pressure cupping devices cannot enable a single person to independently perform cupping on the lower back area.

[0005] This utility model is implemented as follows:

[0006] A self-contained cupping device for the lower back includes a handle with an internal electronic control module. A control key electrically connected to the module is located on the outer wall of the handle. An extension rod with an "L"-shaped structure is connected to the outer end of the handle. An end cap is vertically connected to the end of the extension rod, and an airflow channel is provided inside the end cap. A cupping jar is detachably connected to the inner end of the airflow channel. The bottom of the cupping jar is open, and the top of the cupping jar has a connector for the airflow channel. The handle, extension rod, end cap, and cupping jar form a "J"-shaped structure. A negative pressure pump is installed within the airflow channel. When the negative pressure pump operates, it directs airflow from the side of the airflow channel closest to the cupping jar. The body is pulled away from the other side of the airflow channel; a positioning block is provided on the side of the airflow channel near the tank body, and an electric gripper is provided around the positioning block. The insertion end of the tank body is provided with a slot adapted to the electric gripper. The slot and the electric gripper constitute the disassembly and assembly control structure between the tank body and the end. The insertion end is provided with a sealing plug that can be elastically opened and closed. The sealing plug is provided with an air hole. After the insertion end is inserted into the airflow channel, the positioning block can drive the sealing plug to move towards the bottom of the tank body so that the inner cavity of the tank body is connected to the airflow channel. An elastic reset structure is also provided between the sealing plug and the tank body. The sealing plug and the positioning block constitute the air passage opening and closing structure between the tank body and the airflow channel.

[0007] Based on the above technical solution, both the handle and the extension rod are round rod structures.

[0008] Based on the above technical solution, the airflow channel is provided with an exhaust hole at the end away from the tank body, and several exhaust holes are arranged in a centrally symmetrical manner around the axial center line of the airflow channel.

[0009] Based on the above technical solution, the extension rod is provided with a wiring channel, through which the cables of the negative pressure pump and the electric gripper extend to the inside of the handle and are electrically connected to the electronic control module.

[0010] Based on the above technical solution, the plug-in end of the tank body is provided with a limiting plate, the limiting plate has a first air hole, and the plug-in end has an inverted "T"-shaped perforation at the top of the limiting plate. The sealing plug is fitted into the perforation, and a retaining plate is fixedly connected to the bottom of the sealing plug. The sealing plug has a second air hole and a third air hole at the upper part of the retaining plate. The second air hole and the third air hole form a T-shaped air hole, and the top of the T-shaped air hole penetrates the sealing plug. A spring that can extend and retract longitudinally is abutted between the bottom of the retaining plate and the top of the limiting plate. In the closed state, the retaining plate is tightly fitted to the bottom of the perforation, and the T-shaped air hole is not connected to the inner cavity of the tank. In the connected state, the positioning block abuts against and presses down the sealing plug from the top, the retaining plate is disengaged from the bottom of the perforation, and the T-shaped air hole is connected to the inner cavity of the tank.

[0011] Based on the above technical solution, the card slot is located on the outer wall of the insertion end.

[0012] Based on the above technical solution, a number of first air holes are arranged in a centrally symmetrical manner on the radial periphery of the limiting plate.

[0013] Based on the above technical solution, the insertion end of the positioning block and the tank body is provided with a stepped positioning structure.

[0014] Based on the above technical solution, the bottom of the tank is provided with a gasket made of elastic material.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] Example 1: Combination Figure 1-4 This embodiment discloses a self-contained cupping device for the lower back, which aims to provide a device that allows users to easily operate it themselves to perform cupping therapy on the lower back area.

[0034] like Figure 1As shown, the cupping device specifically includes a handle 100, an extension rod 200, an end 300, and a cup body 600. The handle 100, extension rod 200, end 300, and cup body 600 form a "J"-shaped structure. In use, the handle 100 is gripped by the user, and the extension rod 200 extends the end 300 and cup body 600 to the lower back area. The handle 100 maintains a forward-backward orientation, and the opening of the cup body 600 rests against the target limb in the lower back area. A negative pressure pump 400 is installed inside the end 300, which can draw air out of the cup body 600, creating a negative pressure state inside the cup body 600 to achieve the negative pressure cupping effect. An electrically controlled disengagement structure can be provided between the cup body 600 and the end 300 for convenient separation and control.

[0035] The handle 100 contains an electronic control module, which includes a circuit board and a power supply. The outer wall of the handle 100 has control keys 101 electrically connected to the electronic control module. In this embodiment, there are two control keys 101: one for controlling the start and stop of the negative pressure pump 400, and the other for controlling the opening and closing of the electric gripper 500. The electronic control module, power supply, control keys 101, negative pressure pump 400, and electric gripper 500 are all existing technologies. Their specific structures and working principles will not be described in detail here. Those skilled in the art can select and implement them from existing technologies based on actual operating conditions.

[0036] An extension rod 200 is connected to the outer end of the handle 100. The extension rod 200 has an "L"-shaped structure and is combined with... Figure 3 The extension rod 200 has a wiring channel 340 inside for cable routing and connection between the end 300 and the handle 100. The main function of the extension rod 200 is to extend the working end of the device in a directional manner so that the working end can be operated by a single person to treat the waist and back area.

[0037] Both the handle 100 and the extension rod 200 are round rod structures.

[0038] The extension rod 200 is vertically connected to an end head 300, which is a hollow cylindrical structure. An airflow channel 310 is provided inside the end head 300. A canister 600 is detachably connected to the inner end of the airflow channel 310. The bottom of the canister 600 is open for contacting the limb. The top of the canister 600 is provided with a plug end that connects to the airflow channel 310. The canister 600 is connected to the end head 300 through this plug end.

[0039] Among them, combined Figure 3 and Figure 4As shown, a negative pressure pump 400 is provided in the airflow channel 310. When the negative pressure pump 400 is working, it can draw the gas on the side of the airflow channel 310 close to the tank 600 to the other side of the airflow channel 310. An exhaust port 320 is provided at the end of the airflow channel 310 away from the tank 600. Several exhaust ports 320 are centrally symmetrically arranged around the axial center line of the airflow channel 310. The drawn gas is discharged from the end 300 through the exhaust port 320.

[0040] A positioning block 330 is provided on the side of the airflow channel 310 near the tank 600. The positioning block 330 is fixedly connected to the end 300. The bottom of the positioning block 330 is provided with a stepped structure, which can play a positioning role when connected to the tank 600.

[0041] An electric gripper 500 is provided around the positioning block 330. The electric gripper 500 has a claw body that moves laterally in and outwards, used to clamp and fix the plug-in end of the tank 600 to achieve the connection between the tank 600 and the end head 300. The plug-in end of the tank 600 is provided with a slot 640 adapted to the electric gripper 500. The slot 640 and the electric gripper 500 constitute the disassembly and assembly control structure between the tank 600 and the end head 300. The slot 640 is located on the outer side wall of the plug-in end. The cables of the negative pressure pump 400 and the electric gripper 500 extend through the wiring channel 340 into the handle 100 and are electrically connected to the electronic control module.

[0042] The insertion end of the positioning block 330 into the tank 600 is provided with a stepped positioning structure. The insertion end has an elastically opening and closing sealing plug 630 with air holes. After the insertion end is inserted into the airflow channel 310, the positioning block 330 can drive the sealing plug 630 to move towards the bottom of the tank 600, so that the inner cavity of the tank 600 communicates with the airflow channel 310. An elastic reset structure is also provided between the sealing plug 630 and the tank 600. The sealing plug 630 and the positioning block 330 constitute the air passage opening and closing structure between the tank 600 and the airflow channel 310.

[0043] Specifically, the insertion end of the tank 600 is provided with a limiting plate 610. The outer periphery of the limiting plate 610 is connected and fixed to the inner side wall of the tank 600. The limiting plate 610 is provided with a first air hole 611. A plurality of first air holes 611 are centrally symmetrically arranged on the radial periphery of the limiting plate 610. The first air holes 611 make the space in the inner cavity of the tank 600 located on the upper and lower sides of the limiting plate 610 interconnected, enabling gas exchange.

[0044] Furthermore, the plug-in end has an inverted "T"-shaped perforation at the top of the limiting plate 610, which forms an installation space, and the top of the perforation penetrates the tank body 600. For example... Figure 4As shown, the sealing plug 630 is fitted into the perforation. A retaining plate 631 is fixedly connected to the bottom of the sealing plug 630. The retaining plate 631 is horizontally positioned and parallel to the limiting plate 610. The sealing plug 630 has a second vent 632 and a third vent 633 that are perpendicular to each other at the upper end of the retaining plate 631. The two third vents 633 are located at the bottom of the second vent 632. The top of the second vent 632 penetrates the top of the sealing plug 630. The outer end of the third vent 633 penetrates the side wall of the sealing plug 630 laterally. The second vent 632 and the third vent 633 form a T-shaped vent, that is, the top of the T-shaped vent penetrates the sealing plug 630. A spring 620 that can extend and retract longitudinally is abutted between the bottom of the retaining plate 631 and the top of the limiting plate 610. The spring 620 can extend and retract longitudinally in its free state. The pressure is sufficient to drive the sealing plug 630 upward, so that the T-shaped vent is closed. At this time, the clamping plate 631 is tightly attached to the bottom of the perforation, and the outer end of the third vent 633 is blocked by the inner side of the perforation. The T-shaped vent is not connected to the inner cavity of the tank 600. When the sealing plug 630 is pushed down by the positioning block 330, it will compress the spring 620. That is to say, the positioning block 330 abuts against and presses down the sealing plug 630 from the top, and the clamping plate 631 is separated from the bottom of the perforation. At this time, the T-shaped vent is connected to the inner cavity of the tank 600, that is, the inner cavity of the tank 600 is connected to the airflow channel 310 inside the end 300. In this state, the open end of the tank 600 is attached to the limb, and the negative pressure pump 400 can draw away the gas in the tank 600, so that the inside of the tank 600 is in a negative pressure state.

[0045] In the specific implementation process, the canister 600 is first connected to the bottom of the end 300 using the plug-in terminal. The operator holds the handle 100 with one hand and uses the extension rod 200 to wrap the end 300 and the canister 600 around their back. Using an external mirror to observe the position of the canister 600, and after aligning it with the target position, the operator pulls the handle 100 forward so that the opening of the canister 600 fits against the skin. At this time, the negative pressure pump 400 is activated using the control key 101 to draw out the gas inside the canister 600. A negative pressure state is formed. Then, another control key 101 is used to activate the electric gripper 500 to move outward, releasing the clamping constraint on the insertion end slot 640 of the can 600. After the constraint is released, in conjunction with the outward movement of the handle 100, extension rod 200 and end head 300, the sealing plug 630 loses its inward pushing force, the spring 620 extends and resets, driving the sealing plug 630 to move outward and block the perforation, thus isolating the inner cavity of the can 600 from the external space and continuing to maintain a negative pressure state. This completes the autonomous cupping operation for the waist and back.

[0046] Example 2: Based on Example 1, combined with Figure 5 and Figure 6As shown, to improve the fit and seal between the canister 600 and the limb, a gasket 660 made of elastic material (rubber) is provided at the bottom of the canister 600. Furthermore, a sealing groove 650 is provided at the bottom of the canister 600, the top of the gasket 660 is fixed within the sealing groove 650, and the bottom of the gasket 660 extends to the outside of the sealing groove 650. The bottom of the gasket 660 is provided with horizontally arranged lateral wings 661, and a softening groove 662 is provided at the base of the lateral wings 661. The softening groove 662 enables the lateral wings 661 to have more flexible and lightweight deformation properties, allowing them to deform appropriately according to the actual outer contour of the limb to achieve a better sealing effect.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
