[0045] The negative pressure massager provided by the embodiment of the present invention is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0046] Figure 1 to Figure 3 The structure of the negative pressure massager provided in the first embodiment of the present invention is shown. The negative pressure massager 100 includes at least one housing 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 housing 10 has a first accommodating chamber, which can be used to accommodate various electronic components of the negative pressure massager 100 .

[0048] The top and bottom of the negative pressure chamber housing 20 are both open and hollow inside. The top of the negative pressure chamber housing 20 is fixed to the bottom of the housing 10. A negative pressure chamber 22 is formed inside the negative pressure chamber housing 20. The bottom of the negative pressure chamber housing 20 is open to communicate with the outside. Preferably, the negative pressure chamber housing 20 is surrounded by a cavity wall 21, and the bottom of the housing 10 and the cavity wall 21 of the negative pressure chamber housing 20 together form the negative pressure chamber 22.

[0049] The massage head 30 is disposed at the bottom end of the housing 10 and is accommodated in the negative pressure chamber 22. Preferably, the massage head 30 includes 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 housing 10 or the negative pressure chamber housing 20, and the negative pressure pump 40 is communicated with the negative pressure chamber 22. Preferably, the negative pressure pump 40 is arranged in the first accommodating chamber of the housing 10, and a vent pipe is provided between the housing 10 and the negative pressure chamber 22 of the negative pressure chamber housing 20, and the negative pressure pump 40 is communicated with the negative pressure chamber housing 20 through the vent pipe. It is worth mentioning that the shape of the vent pipe is not subject to any restrictions as long as the negative pressure pump 40 and the negative pressure chamber 22 can ventilate each other, and can be a cylindrical hollow tube body or a square cylindrical hollow tube body, etc. Preferably, the negative pressure pump 40 can also be directly arranged in the negative pressure chamber housing 20, that is, the negative pressure pump 40 and the negative pressure chamber 22 are arranged in the same cavity (negative pressure chamber housing 20), and in this case, a vent pipe is not required.

[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 an air suction port and an air exhaust port, and can continuously form a negative pressure (relative vacuum) at the air suction port, and a slight positive pressure at the exhaust port. The air suction port of the negative pressure pump 40 is located in the negative pressure chamber 22, and the exhaust port of the negative pressure pump 40 is provided on the housing 10. The negative pressure pump 40 compresses and stretches the air in the negative pressure chamber 22 to form a negative pressure, and generates a pressure difference with the external atmospheric pressure at the air suction port. Under the action of the pressure difference, the gas is sucked into the negative pressure chamber 22 and then discharged from the exhaust port.

[0052] The control circuit board 50 is disposed in the housing 10. The control circuit board 50 is electrically connected to the massage head 30 and the negative pressure pump 40 respectively. When the bottom opening of the negative pressure chamber housing 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 chamber 22 to form a negative pressure that meets a predetermined standard in the negative pressure chamber 22. After the negative pressure chamber 22 forms a negative pressure, it can absorb the skin and flesh of the human body part, 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 massager 100 fits the human skin properly, a negative pressure that meets a predetermined standard needs to be formed in the negative pressure chamber 22. Otherwise, if the negative pressure is too large, the negative pressure massager 100 fits the human skin too tightly, so the human skin is easily painful when being adsorbed by the negative pressure massager 100 for a long time, resulting in a poor massage experience; if the negative pressure is too small, the negative pressure massager 100 fits the human skin too loosely, so the negative pressure massager 100 cannot be adsorbed to the human skin, so that the negative pressure massager 100 cannot massage the human body parts, resulting in a poor massage effect.

[0054] The control circuit board 50 of the present invention controls the negative pressure pump 40 to exhaust and / or supply air to the negative pressure chamber 22 to form a negative pressure that meets a predetermined standard in the negative pressure chamber 22. Preferably, the process is a dynamic adjustment process, that is, the negative pressure of the negative pressure chamber 22 is always guaranteed to meet the predetermined standard. If the negative pressure of the negative pressure chamber 22 is too small, the control circuit board 50 controls the negative pressure pump 40 to exhaust the negative pressure chamber 22, that is, further exhaust the air in the negative pressure chamber 22 to increase the negative pressure of the negative pressure chamber 22 until it is adjusted to the standard negative pressure. If the negative pressure of the negative pressure chamber 22 is too large, the control circuit board 50 controls the negative pressure pump 40 to supply air to the negative pressure chamber 22, that is, to deliver the outside air into the negative pressure chamber 22 to reduce the negative pressure of the negative pressure chamber 22 until it is adjusted to the standard negative pressure.

[0055] First, the control circuit board 50 can automatically control the negative pressure pump 40 to exhaust and / or supply air to the negative pressure chamber 22, so as to form a negative pressure that meets the predetermined standard in the negative pressure chamber 22, so as to ensure that the negative pressure massager 100 can achieve a close and comfortable fit with the human skin, so as to ensure a better massage effect and experience. Preferably, an air pressure detection unit 80 is provided in the negative pressure chamber housing 20 of the present invention, such as Figure 4 As shown, the air pressure detection unit 80 is electrically connected to the control circuit board 50, and the control circuit board 50 controls the negative pressure pump 40 to exhaust and / or supply air to the negative pressure chamber 22 according to the current air pressure value detected by the air pressure detection unit 80, so as to form a negative pressure that meets the predetermined standard in the negative pressure chamber 22. Preferably, the air pressure detection unit 80 can detect the current air pressure value of the negative pressure chamber housing 20 in real time, so as to form a negative pressure that meets the predetermined standard in the negative pressure chamber 22 in real time.

[0056] Secondly, the control circuit board 50 controls the negative pressure pump 40 to exhaust and / or supply air to the negative pressure chamber 22 according to the user's instructions, so as to form a negative pressure that meets the predetermined standard in the negative pressure chamber 22, so as to ensure that the negative pressure massager 100 can achieve a close and comfortable fit with the human skin, so as to ensure a better massage effect and experience.

The operation instructions sent by the user through the control unit 91 include an increase negative pressure instruction and a decrease negative pressure instruction. When the control circuit board 50 receives an increase negative pressure instruction, the negative pressure pump 40 is controlled to exhaust the negative pressure chamber 22. When the control circuit board 50 receives a decrease negative pressure instruction, the negative pressure pump 40 is controlled to supply air to the negative pressure chamber 22. The user can send an increase negative pressure instruction and a decrease negative pressure instruction through the control unit 91 according to the current actual feeling.
