Preferably, the first shell body 11 is provided with a first air pipe, and the negative pressure pump 40 communicates with the first negative pressure cavity shell 12 through the first air pipe. The first air pipe only needs to ensure that the negative pressure pump 40 and the first negative pressure cavity 121 can communicate with each other, and the shape of the first air pipe is not limited.

[0059] Preferably, the negative pressure pump 40 can also directly communicate with the first negative pressure cavity shell 12, that is, the negative pressure pump 40 and the first negative pressure cavity shell 12 are arranged in one cavity.

[0060] Preferably, the negative pressure pump 40 adopts a negative pressure vacuum pump, such as a micro vacuum pump. The negative pressure pump 40 has one suction port and one exhaust port, and can continuously form a negative pressure (relative vacuum) at the suction port and a slight positive pressure at the exhaust port. The suction port of the negative pressure pump 40 is located in the first negative pressure cavity 121, and the exhaust port of the negative pressure pump 40 is arranged on the shell body 10. The negative pressure pump 40 compresses and stretches the air in the first negative pressure cavity 121 to form a negative pressure, generates a pressure difference with the outside atmospheric pressure at the suction port, and under the action of the pressure difference, the gas is sucked into the first negative pressure cavity 121 and then discharged from the exhaust port.

[0061] The second massage unit 20 includes a second shell body 21, a second negative pressure cavity shell 22, a second massage head 23, and a control circuit board 50, wherein:

[0062] The second shell body 21 has a second accommodating cavity, which can be used to accommodate various electronic components of the negative pressure massager 100.

[0063] The top end and the bottom end of the second negative pressure cavity shell 22 are open and hollow. The top end of the second negative pressure cavity shell 22 is fixed to the bottom end of the second shell 21. The second negative pressure cavity 221 is formed in the second negative pressure cavity shell 22. The second negative pressure cavity 221 is in communication with the negative pressure pump 40 through the electric connection pipe 30. The bottom end of the second negative pressure cavity shell 22 is open to the outside. Preferably, the second negative pressure cavity shell 22 is formed by being surrounded by a second cavity wall 222.

[0065] The control circuit board 50 is arranged in the second shell 21. The control circuit board 50 is electrically connected with the second massage head 23. The control circuit board 50 is electrically connected with the negative pressure pump 40 and the first massage head 13 of the first massage unit 10 through the electric connection pipe 30.

After the first negative pressure cavity 121 and / or the second negative pressure cavity 221 forms the negative pressure, the human body part can be adsorbed, so that the first massage head 13 and / or the second massage head 23 can contact the human body part, and then the first massage head 13 and / or the second massage head 23 can perform massage operation on the human body part.

[0066] In order to ensure that the negative pressure massage device 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 massage device 100 is too tightly attached to the human skin, so that the human skin is easily painful when being adsorbed by the negative pressure massage device 100 for a long time, thereby resulting in poor massage experience. If the negative pressure is too small, the negative pressure massage device 100 is too loosely attached to the human skin, so that the negative pressure massage device 100 cannot be adsorbed to the human skin, thereby resulting in poor massage effect.

[0067] The control circuit board 50 controls the negative pressure pump 40 to exhaust and / or inhale air from / 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 always meets the predetermined standard. If the negative pressure in the negative pressure cavity is too small, the control circuit board 50 controls the negative pressure pump 40 to exhaust air from the first negative pressure cavity 121 and / or the second negative pressure cavity 221, that is, to further exhaust air from 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 negative pressure pump 40 to inhale air into the first negative pressure cavity 121 and / or the second negative pressure cavity 221, that is, to inhale air from the outside into 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.

[0068] Firstly, the control circuit board 50 can automatically control the negative pressure pump 40 to exhaust and / or inhale air from / 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 ensure that the negative pressure massager 100 can be closely and comfortably attached to the human skin, thereby ensuring better massage effect and experience.

[0069] 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 operation commands sent by the user through the control unit 80 include commands to increase or decrease negative pressure. When the control circuit board 50 receives a command to increase negative pressure, it controls the negative pressure pump 40 to exhaust air from the first negative pressure chamber 121 and / or the second negative pressure chamber 221; when the control circuit board 50 receives a command to decrease negative pressure, it controls the negative pressure pump 40 to supply air to the first negative pressure chamber 121 and / or the second negative pressure chamber 221.
