Alternatively, the second negative pressure pump 42 is provided in the first negative pressure cavity shell 22, and the second negative pressure pump 42 is in communication with the second negative pressure cavity 221.

[0071] Preferably, the second shell 21 is provided with a first air pipe, and the second negative pressure pump 42 is in communication with the second negative pressure cavity shell 22 through a second air pipe. The second air pipe only needs to ensure that the second negative pressure pump 42 and the second negative pressure cavity 221 can communicate with each other, and the shape of the second air pipe is not limited.

[0072] Preferably, the second negative pressure pump 42 can also be directly communicated with the second negative pressure cavity shell 22, that is, the second negative pressure pump 42 and the second negative pressure cavity shell 22 are arranged in one cavity.

[0073] Preferably, the second negative pressure pump 42 adopts a negative pressure vacuum pump, such as a micro vacuum pump. The second negative pressure pump 42 has one suction port and one exhaust port, and a negative pressure (relative vacuum) can be continuously formed at the suction port, and a micro positive pressure is formed at the exhaust port. The suction port of the second negative pressure pump 42 is located in the second negative pressure cavity 221, and the exhaust port of the second negative pressure pump 42 is arranged on the shell 10. The second negative pressure pump 42 compresses and stretches the air in the second negative pressure cavity 221 to form a negative pressure, and a pressure difference is generated between the suction port and the outside atmospheric pressure, so that the gas is sucked into the second negative pressure cavity 221 under the action of the pressure difference, and then discharged from the exhaust port.

[0074] The control circuit board 50 is arranged in the second shell 21, and the control circuit board 50 is electrically connected with the second negative pressure pump 42 and the second massage head 23 respectively. The control circuit board 50 is electrically connected with the first negative pressure pump 41 and the first massage head 13 of the first massage unit 10 through the electrical connection pipe 30 respectively. When the bottom end openings of the first negative pressure cavity shell 12 and the second negative pressure cavity shell 22 are placed on the human body part, the control circuit board 50 controls the first negative pressure pump 41 and / or the second negative pressure pump 42 to exhaust and / or inhale the first negative pressure cavity 121 and / or the second negative pressure cavity 221 respectively, so as to form a negative pressure in the first negative pressure cavity 121 and / or the second negative pressure cavity 221 that meets a predetermined standard.

[0075] In order to ensure that the negative pressure massager 100 is tightly and properly attached to the human skin, a negative pressure that meets a predetermined standard needs to be formed in the first negative pressure cavity 121 and / or the second negative pressure cavity 221. Otherwise, if the negative pressure is too large, the negative pressure massager 100 is too tightly attached to the human skin, and thus the human skin is easily painful when being adsorbed by the negative pressure massager 100 for a long time, thereby resulting in a poor massage experience. If the negative pressure is too small, the negative pressure massager 100 is too loosely attached to the human skin, and thus the negative pressure massager 100 cannot be adsorbed to the human skin, so that the negative pressure massager 100 cannot perform a massage operation on the human body part, thereby resulting in a poor massage effect.

[0076] The control circuit board 50 controls the first negative pressure pump 41 and / or the second negative pressure pump 42 to respectively exhaust and / or inhale air to the first negative pressure cavity 121 and / or the second negative pressure cavity 221, so as to form a negative pressure meeting a predetermined standard in the first negative pressure cavity 121 and / or the second negative pressure cavity 221. Preferably, the process is a dynamic adjustment process, that is, the negative pressure of the first negative pressure cavity 121 and / or the second negative pressure cavity 221 is always guaranteed to meet the predetermined standard. If the negative pressure in the negative pressure cavity is too small, the control circuit board 50 controls the first negative pressure pump 41 and / or the second negative pressure pump 42 to respectively exhaust air to the first negative pressure cavity 121 and / or the second negative pressure cavity 221, that is, to further exhaust air in the negative pressure cavity, so as to increase the negative pressure in the negative pressure cavity, until the negative pressure meeting the standard is adjusted. If the negative pressure in the negative pressure cavity is too large, the control circuit board 50 controls the first negative pressure pump 41 and / or the second negative pressure pump 42 to respectively inhale air to the first negative pressure cavity 121 and / or the second negative pressure cavity 221, that is, to inhale air from the outside to the first negative pressure cavity 121 and / or the second negative pressure cavity 221, so as to reduce the negative pressure in the negative pressure cavity, until the negative pressure meeting the standard is adjusted.

[0077] Firstly, the control circuit board 50 can automatically control the first negative pressure pump 41 and / or the second negative pressure pump 42 to respectively exhaust and / or inhale air to the first negative pressure cavity 121 and / or the second negative pressure cavity 221, so as to form a negative pressure meeting a predetermined standard in the first negative pressure cavity 121 and / or the second negative pressure cavity 221, so as to guarantee that the negative pressure massager 100 can be closely and comfortably attached to the human skin, thereby guaranteeing a better massage effect and experience.

[0078] Preferably, the negative pressure massager 100 further comprises a gas pressure detection unit, which is arranged in the first negative pressure cavity shell 12 and / or the second negative pressure cavity shell 22, and is electrically connected with the control circuit board 50 through the electric connection pipe 30. The control circuit board 50 controls the first negative pressure pump 41 and / or the second negative pressure pump 42 to respectively exhaust and / or inhale air to the first negative pressure cavity 121 and / or the second negative pressure cavity 221 according to the current gas pressure value detected by the gas pressure detection unit, so as to form a negative pressure meeting a predetermined standard.

The negative pressure meeting the predetermined standard means that the negative pressure massager 100 can be closely and comfortably attached to the human skin under the negative pressure.

[0079] As Figure 5In the second embodiment shown, a first air pressure detection unit 71 is provided in the outer shell 12 of the first negative pressure chamber. The first air pressure detection unit 71 is electrically connected to the control circuit board 50 through the electrical connection pipe 30.
