[0002] A jet pump device is a device that uses the energy of a working fluid (usually liquid or gas) to transport another fluid (which can be liquid, gas or solid). During the fluid transportation process, a jet pump device with an anti-clogging structure is often required.

[0003] After searching, the announcement number is CN204663903U, and the name is a jet pump device, and in particular, it relates to a jet pump device that shortens the priming time before starting. Through research and analysis, it is found that although there is an advantage of only filling the return pipe to start the machine, there are still the following disadvantages to a certain extent.

[0004] For example, the jet pump device mentioned above usually does not have a pre-filtering mechanism during use, or usually no anti-clogging mechanism is set in its pre-filtering mechanism, which makes it easy for the impurities in the fluid to accumulate during the fluid transportation process, which may cause a certain impact on the service life of the equipment. In order to solve the above technical problems, we have designed a jet pump device with an anti-clogging structure. Utility Model Content
