[0020] AsFigures 1 to 3 As shown in the figure, a portable negative pressure vacuum pump includes a box body 1, a side-opening door 2, a mobile wheel assembly 3, a U-shaped groove 4, a U-shaped pull rod 5, a rotating plate 6, a rotating shaft 7, a support plate 8, a negative pressure vacuum pump 9, a placement groove 10, a support block 11, a rotating handle rod 12, a connecting rod 13, an intercepting rod 14, a baffle plate 15, an inserting plate 16, a magnetic attraction block 17, a switch handle 18, and an anti-slip pattern 19.

[0021] On the front of the box body 1, there is a side-opening door 2. One side of the inner surface of the side-opening door 2 is hinged to the box body 1, and the other side is locked to the box body 1 through the magnetic attraction block 17. On the outer surface of the side-opening door 2, there is a switch handle 18.

[0022] At the four corners of the bottom of the box body 1, there are mobile wheel assemblies 3. The mobile wheel assembly 3 includes a bracket and wheels installed on the bracket.

[0023] On the top of the box body 1, there is a U-shaped groove 4. Inside the U-shaped groove 4, there is a U-shaped pull rod 5. The two ends of the side rods of the U-shaped pull rod 5 are rotatably installed between the two side walls of the U-shaped groove 4 through a pin shaft. Inside the box body 1, there is a rotating plate 6, and a negative pressure vacuum pump 9 is fixedly installed on the rotating plate 6.

[0024] By installing the negative pressure vacuum pump 9 inside the box body 1 and providing mobile wheel assemblies 3 at the bottom of the box body 1, it can be conveniently moved. Through the U-shaped pull rod 5, the box body 1 can be conveniently dragged for movement. When not in use, it can be stored in the U-shaped groove 4 without occupying additional volume.

[0025] On the top of the box body 1, a baffle plate 15 is rotatably installed through a pin shaft. The baffle plate 15 is located at both ends of the middle groove of the U-shaped groove 4. Between the other end of the baffle plate 15 and the top of the box body 1, there is an inserting plate 16.

[0029] In order to facilitate the connection between the negative pressure vacuum pump 9 and an external container, the present utility model designs a structure that can rotate the negative pressure vacuum pump 9 out for use, which is more convenient. Specifically:

[0030] One side of the bottom of the rotating plate 6 is rotatably installed on the inner bottom plate of the box body 1 through a rotating shaft 7. Between the other side of the bottom of the rotating plate 6 and the inner bottom plate of the box body 1, there is a support plate 8. The support plate 8 is fixed on the side wall of the box body 1. On the inner bottom plate of the box body 1, there is a placement groove 10. Inside the placement groove 10, there is a support block 11. The height of the support block 11 is equal to the distance between the bottom of the mobile wheel assembly 3 and the bottom of the rotating plate 6.

[0031] A rotating handle rod 12 is provided at the top of the turntable 6.

[0032] A connecting rod 13 is provided at the bottom of the rotating handle rod 12, a retaining rod 14 is provided at the bottom of the connecting rod 13, the diameter of the retaining rod 14 is larger than that of the connecting rod 13, a slot is provided at the top of the support plate 8 corresponding to the retaining rod 14, a retaining groove is provided at the bottom of the turntable 6 corresponding to the retaining rod 14, the height of the retaining groove is larger than that of the retaining rod 14, a through hole runs through between the retaining groove and the top of the turntable 6, and the connecting rod 13 is inserted into the through hole.

[0033] During use, the rotating handle rod 12 is lifted upwards to disengage the retaining rod 14 from the slot at the top of the support plate 8 and enter the retaining groove at the bottom of the turntable 6, and then the turntable 6 is rotated out of the box body 1 by dragging the rotating handle rod 12, and then the support block 11 is taken out and supported between the ground and the bottom of the turntable 6. At this time, the intake pipe and the outlet pipe of the negative pressure vacuum pump 9 are exposed, which is convenient for connection with an external container for use. When not in use, it is reset and put into the box body 1 again.

[0034] The above has described the present utility model by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the present utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
