[0045] The negative pressure massager provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0046] Figures 1-3 The structure of the negative pressure massager provided by the embodiment of the present application is shown. The negative pressure massager 100 comprises at least one shell 10, at least one massage head 30, at least one negative pressure pump 40, and at least one control circuit board 50, wherein:

[0047] The shell 10 has a first accommodating cavity, which can be used to accommodate various electronic components of the negative pressure massager 100.

[0048] The top end and the bottom end of the negative pressure cavity shell 20 are both open and hollow. The top end of the negative pressure cavity shell 20 is fixed to the bottom end of the shell 10. The negative pressure cavity shell 20 forms a negative pressure cavity 22 inside. The bottom end of the negative pressure cavity shell 20 is open and communicates with the outside. Preferably, the negative pressure cavity shell 20 is formed by being surrounded by a cavity wall 21. The bottom end of the shell 10 and the cavity wall 21 of the negative pressure cavity shell 20 jointly form the negative pressure cavity 22.

[0049] The massage head 30 is arranged at the bottom end of the shell 10 and accommodated in the negative pressure cavity 22. Preferably, the massage head 30 comprises an electrode sheet, a vibration motor, etc., so that the massage head 30 can perform pulse massage, vibration massage, etc.

[0050] The negative pressure pump 40 is arranged in the shell 10 or the negative pressure cavity shell 20, and the negative pressure pump 40 is in communication with the negative pressure cavity 22. Preferably, the negative pressure pump 40 is arranged in the first accommodating cavity of the shell 10, and an air pipe is arranged between the shell 10 and the negative pressure cavity 22 of the negative pressure cavity shell 20, and the negative pressure pump 40 is in communication with the negative pressure cavity shell 20 through the air pipe. It is worth mentioning that the air pipe only needs to ensure that the negative pressure pump 40 and the negative pressure cavity 22 can communicate with each other, and the shape of the air pipe is not limited, which can be a cylindrical hollow pipe or a square column hollow pipe. Preferably, the negative pressure pump 40 can also be directly arranged in the negative pressure cavity shell 20, that is, the negative pressure pump 40 and the negative pressure cavity 22 are arranged in the same cavity (the negative pressure cavity shell 20), and at this time, the air pipe does not need to be arranged.

[0051] 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 a negative pressure (relative vacuum) can be continuously formed at the suction port, and a slight positive pressure is formed at the exhaust port. The suction port of the negative pressure pump 40 is located in the negative pressure cavity 22, and the exhaust port of the negative pressure pump 40 is arranged on the shell 10. The negative pressure pump 40 compresses and stretches the air in the negative pressure cavity 22 to form a negative pressure, and a pressure difference is generated between the suction port and the outside atmosphere, and under the action of the pressure difference, the gas is sucked into the negative pressure cavity 22 and then discharged from the exhaust port.

[0052] The control circuit board 50 is arranged in the shell 10, and the control circuit board 50 is electrically connected with the massage head 30 and the negative pressure pump 40 respectively. When the bottom end opening of the negative pressure cavity shell 20 is placed on a human body part, the control circuit board 50 controls the negative pressure pump 40 to exhaust and / or supply air to the negative pressure cavity 22, so as to form a negative pressure in the negative pressure cavity 22 that meets a predetermined standard. After the negative pressure cavity 22 forms a negative pressure, the flesh of the human body part can be adsorbed, so that the massage head 30 can contact the human body part, and then the massage head 30 can perform a massage operation on the human body part.

[0053] In order to ensure that the negative pressure massage device 100 is closely attached to the human skin, a negative pressure that meets a predetermined standard needs to be formed in the negative pressure cavity 22. Otherwise, if the negative pressure is too large, the negative pressure massage device 100 is too tightly attached to the human skin, and thus the human skin is easily adsorbed by the negative pressure massage device 100 for a long time, which causes a pain feeling and thus leads to a poor massage experience. If the negative pressure is too small, the negative pressure massage device 100 is too loosely attached to the human skin, and thus the negative pressure massage device 100 cannot be adsorbed to the human skin, which causes the negative pressure massage device 100 to be unable to massage the human body part, and thus leads to a poor massage effect.

[0054] The control circuit board 50 controls the negative pressure pump 40 to exhaust and / or send air to the negative pressure cavity 22, so as to form the negative pressure meeting the predetermined standard in the negative pressure cavity 22. Preferably, the process is a dynamic adjustment process, that is, the negative pressure of the negative pressure cavity 22 is always guaranteed to meet the predetermined standard. If the negative pressure of the negative pressure cavity 22 is too small, the control circuit board 50 controls the negative pressure pump 40 to exhaust the air in the negative pressure cavity 22, that is, to further exhaust the air in the negative pressure cavity 22, so as to improve the negative pressure of the negative pressure cavity 22, until the standard negative pressure is adjusted. If the negative pressure of the negative pressure cavity 22 is too large, the control circuit board 50 controls the negative pressure pump 40 to send air to the negative pressure cavity 22, that is, to send the air outside to the negative pressure cavity 22, so as to reduce the negative pressure of the negative pressure cavity 22, until the standard negative pressure is adjusted.

[0055] Firstly, the control circuit board 50 can automatically control the negative pressure pump 40 to exhaust and / or send air to the negative pressure cavity 22, so as to form the negative pressure meeting the predetermined standard in the negative pressure cavity 22, so as to guarantee that the negative pressure massager 100 can be closely and comfortably attached to the human skin, and to guarantee that the massage effect and experience are better. Preferably, the negative pressure cavity shell 20 is provided with an air pressure detection unit 80, as shown in the figure, the air pressure detection unit 80 is electrically connected with the control circuit board 50, and the control circuit board 50 controls the negative pressure pump 40 to exhaust and / or send air to the negative pressure cavity 22 according to the current air pressure value detected by the air pressure detection unit 80, so as to form the negative pressure meeting the predetermined standard in the negative pressure cavity 22. Preferably, the air pressure detection unit 80 can detect the current air pressure value of the negative pressure cavity shell 20 in real time, so as to form the negative pressure meeting the predetermined standard in the negative pressure cavity 22 in real time. Figure 4

[0056] Secondly, the control circuit board 50 controls the negative pressure pump 40 to exhaust and / or send air to the negative pressure cavity 22 according to the user instruction, so as to form the negative pressure meeting the predetermined standard in the negative pressure cavity 22, so as to guarantee that the negative pressure massager 100 can be closely and comfortably attached to the human skin, and to guarantee that the massage effect and experience are better. Preferably, the negative pressure massager 100 further comprises a control unit 91, as shown in the figure, which is arranged on the shell 10, and the control unit 91 is electrically connected with the control circuit board 50, and the control unit 91 is used for various control operations of the user. The control circuit board 50 controls the negative pressure pump 40 to exhaust and / or send air to the negative pressure cavity 22 according to the operation instruction of the control unit 91, so as to form the negative pressure meeting the predetermined standard in the negative pressure cavity 22. The operation instruction sent by the user through the control unit 91 includes an increase negative pressure instruction and a decrease negative pressure instruction, when the control circuit board 50 receives the increase negative pressure instruction, the negative pressure pump 40 is controlled to exhaust the negative pressure cavity 22, and when the control circuit board 50 receives the decrease negative pressure instruction, the negative pressure pump 40 is controlled to send air to the negative pressure cavity 22. The user can send the increase negative pressure instruction and the decrease negative pressure instruction through the control unit 91 according to the current actual feeling. Figures 3-4 ​​
