The negative pressure generating device is connected between the intake hole and the exhaust hole, and a filter is provided between the cupping device and the intake hole to prevent essential oils or liquid preparations from entering the main body. A functional head is also provided inside the cupping device, and the massager's functional units, such as the electrode sheet and phototherapy unit, are all provided within the functional head. To provide space within the cupping device to accommodate the functional head, the overall volume of the cupping device becomes large, which increases the overall volume of the massager and makes it inconvenient for users to carry and use. The essential oils or liquid preparations are easily adsorbed by the functional head and the gap between the functional head and the filter, making these locations difficult to clean and prone to accumulation of dirt.
[0004] Therefore, there is a need to design a negative pressure massager that is compact in structure and easy to clean. Summary of the Invention [Problem to be solved by the invention]
[0005] In order to overcome the defects and shortcomings of the prior art, the present invention aims to design a small negative pressure massager, which, given the limited volume of the massager, further expands the working area of the massager, makes the structure more compact, and effectively avoids the accumulation of dirt and grime that may affect the use of the massager.

DETAILED DESCRIPTION OF THE INVENTION
[0018] The technical solution of the present invention will be further illustrated by the following examples.
[0019] The present invention provides a small-sized negative pressure massage machine, which, as shown in FIGS. 1 to 7, comprises a main body 2 and a control circuit board. The main body 2 has a negative pressure cup 1 at its tip. The negative pressure cup 1 has a suction nozzle 14, which has a through-hole. The negative pressure cup 1 has a plurality of electrodes on its tip surface, including at least one positive electrode 11 and at least one negative electrode 12, with insulating regions 13 between each electrode. A receiving chamber is formed on the side wall of the negative pressure cup 1, and a plurality of LED lamp beads 15 are provided in the receiving chamber. The side wall of the negative pressure cup 1 is made of a light-transmitting material. As shown in FIGS. 8 and 9, the plurality of electrodes and the plurality of LED lamp beads 15 are electrically connected to the control circuit board. An EMS driving circuit controls the electrodes, and an LED light driving circuit drives the LED lamp beads. This effectively utilizes the space at the tip of the negative pressure cup 1, thereby reducing the volume of the negative pressure cup 1. When in use, conductive gel is applied to the skin, conduction occurs between the positive electrode 11 and the negative electrode 12 to generate a weak current, and a weak current massage is performed on the skin.
[0020] Here, in this embodiment, one positive electrode 11 and one negative electrode 12 are provided at the end of the side wall of the negative pressure cup 1, both of which are semi-circular and are arranged symmetrically on the tip surface of the negative pressure cup 1, and the covering area of the electrodes is further expanded on the premise that the volume of the negative pressure cup 1 remains unchanged.
[0021] Specifically, the tip surfaces of the poles and the tip surface of the insulating region 13 are located on the same horizontal plane, which improves the adsorption effect.
[0022] Specifically, the electrode is electrically connected to the control circuit board by a screw fastener 16, and a connecting tube is further provided at the rear end of the electrode, and the connecting end of the screw fastener 16 is screw-connected to the connecting tube through the control circuit board, and the screw fastener 16 provides electrical conductivity between the control circuit board and the electrode.
[0023] Specifically, the vacuum cup 1 further includes a filtering unit 3 detachably connected to the suction nozzle 14, the filtering unit 3 comprising a rubber sleeve 31 and a filtering element. The rubber sleeve 31 is detachably fitted onto the suction nozzle 14, and the filtering element is disposed on the rubber sleeve 31 or between the rubber sleeve and the suction nozzle 14, and includes a waterproof filtering membrane, a filtering net, and / or a filtering felt 32, which provides better filtering, a simpler structure, and no residue. When the vacuum massager is in use, after the liquid formulation and essential oil enter the vacuum cup 1, the filtering elements, such as the waterproof filtering membrane, the filtering net, and / or the filtering felt 32, filter the liquid formulation out of the suction nozzle 14. The filtering unit 3 is detachable, and the rubber sleeve 31 can be periodically removed for cleaning or to replace the filtering element.
[0024] Specifically, a storage battery 22 and an air pump 23 are provided inside the main body 2, and both the storage battery 22 and the air pump 23 are electrically connected to the control circuit board. The air pump 23 has an intake hole 231 that communicates with the suction nozzle 14 and an exhaust hole 232 that communicates with the outside. As shown in Figure 10, the air pump drive circuit controls the exhaust of the air pump 23, and discharges air from the main body 2 through the exhaust hole 232.
[0025] Specifically, a push button switch 21 is provided on the side wall of the main body 2. The push button switch 21 is electrically connected to the control circuit board and includes a power button and a light therapy button. As shown in FIG. 11, the power button is electrically connected to the main control driving circuit to control the on / off of the vacuum cup 1. The light therapy button is electrically connected to the LED light driving circuit to adjust the wavelength of the LED lamp beads 15. By switching the light therapy button, the color of the LED lamp beads 15 can be changed. Different colors have different light transmittances, so the depth of the skin effect also varies.
[0026] Specifically, a USB interface 24 is further provided on the side wall of the main body 2, and the USB interface 24 is electrically connected to the control circuit board, and as shown in Figure 12, the USB interface 24 is connected to a charging circuit to charge the storage battery 22, and the negative pressure massager can be used wirelessly when there is remaining power in the storage battery 22. A dustproof cap is further provided on the outside of the USB interface 24, and when there is no need to charge, the dustproof cap can be used to cover the USB interface 24 to prevent dust accumulation or contamination of the medicine.
[0027] In this embodiment, the grip 4 is composed of a disk and a connecting rod, and the disk is connected and fixed to the main body 2 by the connecting rod, and the surface of the disk is recessed inward to make it easier to place the thumb. In other embodiments, the grip 4 may have other shapes as long as it is easy to grip.
[0028] To use this negative pressure massager, first apply conductive gel to the skin, place the negative pressure cups 1 on the area to be massaged, and press the power button. The main control drive circuit activates the massager, and the EMS circuit drive circuit activates the electrodes to discharge, generating a weak current when in contact with the skin, providing a weak current massage to the skin. The positive and negative electrodes 11 and 12 of the negative pressure cups 1 fully utilize the space at the ends of the negative pressure cups 1, reducing the massager's volume and increasing the contact area with the skin. The air pump drive circuit activates the air pump 23, drawing air through the intake hole 231 and expelling it from the negative pressure cups 1 through the exhaust hole 232, generating negative pressure within the negative pressure cups 1 and simulating cupping to massage various parts of the body. During the massage, essential oils or medicinal substances are applied to the skin, and the negative pressure draws the essential oils or medicinal substances into the main body 2, eliminating the risk of damaging the negative pressure massager. After use, the rubber sleeve 31 and filter mesh can be removed and washed, and the filter felt 32 can be replaced regularly to prevent bacterial growth. When the light therapy button is pressed, the LED lamp beads 15 pass through the side wall and irradiate the skin with light, providing light therapy to the skin. The LED light driving circuit can be adjusted to change the color of the LED lamp beads 15 and vary the depth of the skin to which the light therapy effect is applied. Electrodes are attached to the end surface of the negative pressure cup 1, and the LED lamp beads 15 are installed in the cavity in the side wall, which better utilizes the structural features of the negative pressure cup 1 and makes the negative pressure massage structure more compact, thereby reducing the volume of the negative pressure massager.
[0029] The above examples only represent some embodiments of the present invention, and although the description is specific and detailed, it does not limit the technical scope of the present invention. Those skilled in the art may make multiple modifications and improvements without departing from the concept of the present invention, and all of these fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims. [Explanation of symbols]
