As shown in fig. 1 and 2, an embodiment of the present invention provides a portable suction apparatus, which includes a main body and a liquid storage bottle 4. The host computer includes preceding housing 1 and back housing 2, preceding housing 1 and back housing 2 lock fixed connection. The front cover shell 1 and the rear cover shell 2 are buckled with each other to form an accommodating cavity inside. A negative pressure pump 3 is arranged in the containing cavity. The negative pressure pump 3 is connected with the liquid storage tank 4 through an air pipe and provides negative pressure for the liquid storage tank 4, and the other air pipe connected with the liquid storage tank 4 is contacted with the body part of the patient.

A first shock absorption pad 5 is arranged between the negative pressure pump 3 and the front housing 1, and a first shock absorption pad 5 is also arranged between the negative pressure pump 3 and the rear housing 2.

The negative pressure pump 3 inevitably generates vibration and noise during operation, which may interfere with medical work to some extent and affect the experience of the patient. The shock absorption pad is arranged between the negative pressure pump 3 and the housing, so that the vibration amplitude of the negative pressure pump 3 when the aspirator works can be reduced, and the noise can be reduced; meanwhile, secondary noise which can be caused by hard collision between the vibration and the housing of the negative pressure pump 3 can be avoided.

As shown in fig. 3, preferably, the inner walls of the front housing 1 and the rear housing 2 are provided with a support column 21, the first damping pad 5 is disposed on the support column 21, and the first damping pad 5 abuts against the side wall of the negative pressure pump 3.

Specifically, the supporting column 21 is cylindrical, and the axis of the supporting column 21 is perpendicular to the inner wall of the front housing 1 or the rear housing 2. The axle center of support column 21 is equipped with the mounting hole, is equipped with the screw thread on the mounting hole inner wall. The first cushion 5 is also cylindrical, and the first cushion 5 and the supporting pillar 21 are coaxial. And a mounting column is arranged on one end part plane of the first shock pad 5, a thread is arranged on the outer wall of the mounting column, the mounting column penetrates into the mounting hole of the support column 21, and the mounting column is screwed with the mounting hole through the thread.

Alternatively, the first cushion 5 may be made of a material having a shock absorbing property such as rubber or polyurethane.

Reinforcing ribs 22 are arranged on the inner wall of the front housing 1 and/or the rear housing 2, the reinforcing ribs 22 are used for connecting different supporting columns 21, and the outer wall of each supporting column 21 is also provided with the reinforcing ribs 22 surrounding the supporting column 21. One side of the reinforcing rib 22 is connected with the outer wall of the supporting column 21, and the other side of the reinforcing rib 22 is fixedly connected with the inner wall of the front housing 1 or the rear housing 2. In this embodiment, four support columns 21 are arranged on the inner wall of the front housing 1 in a rectangular distribution; correspondingly, four support columns 21 which are distributed in a rectangular shape are also arranged on the inner wall of the rear housing 2, and the support columns 21 on the inner wall of the front housing 1 correspond to the support columns 21 on the inner wall of the rear housing 2 in a front-back mode, so that the support forces of the first shock absorption pads 5 clamped on the front side and the rear side of the negative pressure pump 3 are balanced. Alternatively, the reinforcing beads 22 may be long enough to be connected between two support columns 21.

Because the supporting column 21 is connected with the first shock absorption pad 5, the first shock absorption pad 5 directly abuts against the negative pressure pump 3, and therefore the supporting column 21 indirectly bears the vibration of the negative pressure pump 3. The reinforcing ribs 22 can effectively reinforce the supporting columns 21 and prolong the service life of the supporting columns 21.

Preferably, the bottom of the main frame is further provided with four second shock absorbing pads 6 which are distributed in a rectangular shape. Wherein, preceding housing 1 bottom is equipped with two second shock pads 6, and rear housing 2 bottom is equipped with two second shock pads 6. The second shock pad 6 of host computer bottom also can reach vibrations and noise when reducing the host computer and using, simultaneously, because the shock pad adopts elastic damping material (for example rubber), still can make more stable, the difficult slip that the host computer was placed.

As shown in fig. 4, the negative pressure pump 3 of the present embodiment is provided with two air inlet holes and two air outlet holes.

The air pipes connected to the two air outlets are connected to two ports of a three-way joint 36, and the other port of the three-way joint 36 is connected to the air outlet pipe 32.
