AI Technical Summary
The existing vacuum systems of medical aesthetic equipment emit noise through the air inlet and outlet of the isolation box during operation, resulting in poor noise reduction and low heat dissipation efficiency, which affects the performance and lifespan of the equipment.
Design a vacuum pump assembly comprising a housing, an expansion chamber, and a fan. By designing the dimensions of the air inlet, outlet, and vent of the expansion chamber, noise is reduced using acoustic principles, and heat is dissipated by airflow.
It effectively reduces the noise transmission of vacuum pumps, improves heat dissipation efficiency, and extends the service life of equipment. It is suitable for a variety of equipment that requires noise reduction and heat dissipation.

Abstract
Claims
1. A vacuum pump assembly for use in a skin treatment device for suctioning air between the device and the skin to attract the skin, characterized in that, include: A housing with an air inlet and an air outlet, forming an airflow between the air inlet and the air outlet; the housing houses the vacuum pump, and the airflow carries away the heat generated by the vacuum pump during operation and discharges it through the air outlet; and At least one expansion chamber is disposed on the inner wall of the box, and the expansion chamber has at least one air outlet along the airflow direction; The dimensions of the air inlet, air outlet, and air outlet are all smaller than the cross-sectional area of the expansion chamber, in order to reduce the noise generated by the vacuum pump during operation.
2. The vacuum pump assembly of claim 1, wherein, The vacuum pump assembly includes at least a first expansion chamber with a first air inlet and at least a second expansion chamber with a second air inlet. The first expansion chamber is located at the air inlet and communicates with the air inlet, and the second expansion chamber is located at the air outlet and communicates with the air outlet.
3. The vacuum pump assembly of claim 2, wherein, The first expansion chamber includes a first connecting pipe, which is located at the first air outlet and communicates with the first air outlet. The second expansion chamber includes a second connecting pipe, which is located at the second air outlet and communicates with the second air outlet.
4. The vacuum pump assembly of claim 1, wherein, The air inlet is located at the bottom of the housing, and the air outlet is located at the top of the housing. Air with a lower temperature at the bottom of the housing is drawn into the vacuum pump through the air inlet, carrying away the heat generated by the operation of the vacuum pump and being discharged through the air outlet.
5. The vacuum pump assembly of claim 1, wherein, The interior surface of the expanded room is provided with a sound insulation layer.
6. The vacuum pump assembly of claim 1, wherein, The inner surface of the expansion chamber is provided with a sound-absorbing layer.
7. The vacuum pump assembly as claimed in claim 1, characterized in that, The expansion chamber is provided with at least two baffles that guide the airflow, and the at least two baffles divide the expansion chamber into a labyrinthine airway.
8. The vacuum pump assembly of claim 1, wherein, The vacuum pump assembly also includes a fan located inside the housing above the vacuum pump, for guiding air from the air inlet to the air outlet, the vacuum pump, and the air outlet to form the airflow.
9. The vacuum pump assembly of claim 1, wherein, The vacuum pump assembly also includes a mounting column, a mounting plate is mounted on the top of the mounting column, the vacuum pump is mounted on the top of the mounting plate, the mounting plate is provided with shock-absorbing pads, and the mounting column is fitted with shock-absorbing springs.
10. A skin treatment device characterized by, include: Vacuum pump assembly as described in any one of claims 1 to 9; A vacuum system, comprising a proportional valve, a two-position three-way valve, an air filter, and a water filter connected to a vacuum pump in a vacuum pump assembly; the air filter inlet is connected to the external environment; the proportional valve inlet is connected to the air filter outlet; and the proportional valve outlet is connected to the water filter via a pipe. One port of the two-position three-way valve is connected to the vacuum pump in the vacuum pump assembly via a pipe; another port of the two-position three-way valve is connected to the external environment via a pipe; and yet another port of the two-position three-way valve is connected to the proportional valve outlet via a pipe. A handheld device, which is connected to the water filter in the vacuum system via a pipe.
