Abstract

The invention relates to a secondary lifting device of a vacuum system, which has the advantages of having simple structure and convenient usage, being capable of completely solving the height difference of the vacuum pipeline and the lifting position, and the like. The structure comprises at least one secondary lifting device which is arranged at the vacuum lifting critical height between the toilet stool and the vacuum pipeline and connected with at least one toilet stool.

Description

technical field [0001] The invention belongs to the field of vacuum technology, in particular to a secondary lifting device of a vacuum system suitable for a vacuum toilet. Background technique [0002] At present, the maximum lifting height of the vacuum used by the vacuum toilet is 4 meters, and the height of the underground plaza or high hall is in a critical state of vacuum lifting, resulting in an unsatisfactory effect of vacuum lifting, which limits the application range of the vacuum system. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a secondary lifting device for a vacuum system which has the advantages of simple structure, convenient use, and can completely solve the problem of the height difference between the vacuum pipeline and the lifting place. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A secondary lifting device of a va...
