[0028] In this embodiment 1, when the user selects to use the inhalation state, the massager body 1 can be placed on the user's body. At this time, the air pump 7 is always working. The gas will be drawn from the first pipe 4 through the air pump 7, and a negative pressure state will be formed in the negative pressure chamber 2. After passing through the air pump 7, the gas is discharged from the third pipe 6 into the gas circulation chamber 3, and then discharged into the gas circulation chamber 3 through the exhaust gap 16 to form the inhalation state.

[0029] In this embodiment 2, when the user selects to use the pressure relief state, the massager body 1 is placed on the user's body. At this time, the air pump 7 is always working. Then, the pressing part 12 can be pressed, and the contact part 13 retracts inward. The gas drawn from the first pipe 4 by the air pump 7 is discharged into the gas circulation chamber 3 through the third pipe 6 after passing through the air pump 7. At this time, the sealing part 11 separates from the second pipe opening 19, and the gas flows back from the second pipe 5 to the position of the first pipe 4, so that the negative pressure in the negative pressure chamber 2 disappears and a circuit is formed. At this time, the massager body 1 can be separated from the user.

[0030] In this embodiment 3, when the user selects the massager body 1, which is not located on the gas circulation chamber 3, to use the inhalation state, the massager body 1 can be placed on the user's body. At this time, the air pump 7 is always working, and the gas will be drawn from the first pipe 4 through the air pump 7. A negative pressure state will be formed in the negative pressure chamber 2. After the gas passes through the air pump 7, it is discharged from the third pipe 6 to the outside of the massager body 1 to form the inhalation state.

[0031] In this embodiment 4, when the user selects the massager body 1 in the depressurization state where the third pipe 6 is not located on the gas circulation chamber 3, the massager body 1 is placed on the user's body. At this time, the air pump 7 is always working. Then, the pressing part 12 can be pressed, and the contact part 13 retracts inward. The gas drawn from the first pipe 4 by the air pump 7 is discharged from the third pipe 6 to the outside of the massager body 1. At this time, the sealing part 11 separates from the second pipe opening 19, and the gas flows back from the second pipe 5 to the position of the first pipe 4, so that the negative pressure in the negative pressure chamber 2 disappears and a circuit is formed. At this time, the massager body 1 can be separated from the user.

[0032] The exhaust gap 16 provided in this utility model ensures that even if water enters the massager body 1, it will not enter the massager body 1 and damage the components. It also allows water vapor to be discharged from the massager body 1 through the exhaust gap 16, giving the massager body 1 a certain degree of waterproofing. This prevents water vapor from remaining inside the massager body 1 during depressurization or air intake, thus avoiding affecting the use of the massager body 1 and preventing damage to internal components. Furthermore, the gas circulation chamber 3 is in a sealed state when the massager body 1 is working, serving as a separate cavity and preventing water vapor from entering the massager body 1.
