Description

Technical Field

[0001] This utility model relates to a vacuum pump, specifically a vacuum pump oil storage area formed by internal expansion. In this way, when the vacuum pump is accidentally overturned, the vacuum pump oil can be stored in the storage area, thereby preventing oil leakage. Background Technology

[0002] A vacuum pump is a specialized device for creating a vacuum. Its external structure typically includes an oil tank, a support, and an outlet, while its internal components include a pump body and vacuum pump oil. In order to discharge the pumped gas, the internal structure of a vacuum pump is connected to the outside through a nozzle. Therefore, if a vacuum pump is accidentally overturned, the oil inside the pump will leak out from the nozzle side, causing an oil leak problem.

[0003] To address the aforementioned issues, some designs incorporate unique trap structures on the air nozzle to intercept pump oil flow, while others use flow-blocking pipe structures inside the pump body to impede pump oil flow. However, these optimization methods present some complex challenges. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum pump with anti-tipping and oil leakage prevention. The technical problem to be solved is: to design an anti-tipping and oil leakage structure to avoid oil leakage when the vacuum pump accidentally tipes over.

[0005] A vacuum pump with anti-overturning and oil leakage protection includes an oil tank shell, a bracket, and a pump body assembly. The oil tank shell has a first oil storage chamber, and the pump body assembly is mounted on the mounting part of the bracket. A cavity is formed between the mounting part and the outer wall of the bracket to form a second oil storage chamber. The oil tank shell and the bracket are assembled and sealed to each other, ensuring that the first oil storage chamber and the second oil storage chamber form an integrated cavity to store pump oil and thus prevent pump oil leakage.

[0006] The mounting part has an arc surface, the outer wall of the bracket has a straight plate surface, and the second oil storage cavity is formed by the arc surface and the straight plate surface.

[0007] The oil tank shell has an air outlet on one side opposite the pump body assembly, and an air nozzle is installed on the air outlet.

[0008] The capacity of the integrated cavity is such that the pump oil level after the vacuum pump flips over is lower than the air outlet of the oil tank shell.

[0009] The second oil storage chamber extends in a direction aligned with the rotation direction of the pump body assembly.

[0010] The beneficial effects of this utility model are: by designing a first oil storage chamber inside the oil tank shell and a second oil storage chamber on the bracket, the capacity of the above-mentioned oil storage chambers can meet the requirements of the pump oil under normal working conditions or accidental tipping over, thereby preventing the pump oil from flowing out of the air nozzle at the air outlet.

[0012] Please refer to Figures 1 to 6 The figure shows a vacuum pump with anti-tipping and oil leakage protection. It mainly consists of an oil tank shell 1, a support 2, a pump body assembly 3, a handle 4, an air nozzle 5, and a power supply 6. This application expands the capacity of the oil tank shell 1 and the support 2 to store pump oil 7. The capacity is sufficient for the normal operation of the pump oil 7, and ensures that the oil level of the pump oil 7 is below the air nozzle 5 in the event of an accidental tipping over, thus preventing oil leakage. In practical applications, the above components can be further optimized, such as by improving their shape, structure, material, and quantity, or by using existing components for equivalent replacement, or by adding other components, thereby improving the practicality of the vacuum pump.

[0013] The oil tank shell 1 in the figure is a frame structure with an opening, forming a first oil storage chamber 12 inside. Its top and sides have holes for installing the air nozzle 5 or oil cap. These openings facilitate sealing and assembly with the bracket 2 using bolts and sealing strips. The air nozzle 5 is installed on the air outlet 11 and remains opposite to the pump body assembly 3. The inner cavity of the oil tank shell 1 partially accommodates a portion of the pump body assembly 3, partially accommodates the pump oil 7, and the remaining portion forms a certain amount of space.

[0014] The bracket 2 in the figure is mainly used to install and fix the pump body assembly 3. The bracket 2 has a mounting part 21 structure at the installation position with the pump body assembly 3. The outer walls of the front, rear, and top positions of the bracket 2 together with the mounting part 21 form a second oil storage cavity 22 structure with an opening. As shown in the figure, the mounting part 21 is an arc surface 211 structure, and the outer walls of the front, rear, and top positions of the bracket 2 are straight plate surfaces 23 structures. Thus, the second oil storage cavity 22 is an irregular structure formed by the arc surface 211 and the straight plate surface 23. Of course, in practical applications, the arc surface 211 and the straight plate surface 23 can also be designed with different shapes. In order to maintain sufficient oil storage space, the extension direction of the second oil storage cavity 22 is designed to be aligned with the direction of the rotation axis 31 of the pump body assembly 3, thereby replacing the original structure in the bracket 2 where the outer wall of the bracket 2 and the mounting part 21 are only connected by a flat plate. This expands the space between the mounting part 21 and the outer wall of the bracket 2 to store pump oil 7. When the bracket 2 is sealed and assembled with the oil tank cap, the first oil storage chamber 12 and the second oil storage chamber 22 can form an integrated cavity structure to store the pump oil 7. This integrated structure prevents leakage of the pump oil 7. Specifically, as shown in the figure... Figure 1 and Figure 2 As shown.

[0015] The pump body assembly 3, handle 4, air nozzle 5, power supply 6 and other components in the figure can all be designed using existing components, as long as they can meet the design requirements with the oil tank shell 1 and bracket 2.
