The utility model relates to the technical field of electrostatic purification, in particular to an electrostatic purification device which comprises a device shell and an electrostatic field area, and the electrostatic field area is installed in the device shell. A handle drives a connecting column, a connecting plate and a clamping block to move upwards, so that the clamping block leaves a clamping groove, the connecting plate extrudes a first compression spring upwards, then a dust collection grid plate is pulled outwards, the lower portion of the dust collection grid plate leaves a limiting frame, then the dust collection grid plate can be integrally taken out to be cleaned, and installation can be conducted through reverse operation after cleaning is completed. According to the device, the dust collection grid plate is easy to disassemble and assemble, workers do not need to disassemble all screws through tools to take down the screws for cleaning, time is effectively saved, the device can be used in time subsequently, and the situation that follow-up installation is difficult due to the fact that the screws are lost does not exist.

The utility model provides a portable cleaning device with a fool-proof structure. The portable shell is provided with a vacuum chamber, the flip cover assembly is used for shielding the vacuum chamber, the dust bag assembly is connected with the flip cover assembly, the ejection piece is arranged on the flip cover assembly, one end of the ejection piece can be in contact with the dust bag assembly, and the other end of the ejection piece can be in contact with a neglected loading protection block. Wherein the dust bag assembly comprises a dust bag and a dust bag fixing piece located at one end of the dust bag, and the turning cover assembly comprises a dust bag connecting module and a rotating cover for fixing the dust bag connecting module and the ejection piece. The utility model has the advantages that neglected loading of the dust bag is prevented, a user is reminded to install the dust bag in time, and the working reliability is ensured.

The utility model discloses a linear motor with power -off anti -drop, relates to linear motor field, including motor main part and branch plate, one side fixedly connected with connecting block of branch plate, be equipped with the sliding slot in the inside of connecting block, the inside sliding connection of sliding slot has the sliding block, the front side fixedly connected with moving plate of sliding block, one side of moving plate is provided with telescopic link, and the outside of telescopic link is sleeved with spring, the utility model's advantage lies in: through telescopic link, spring, sliding block, moving plate, spacing post, fixed plate etc. Component can be positioned to magnetic shaft, and then can avoid its falling due to gravity when power -off, can also prolong the life of use simultaneously. Through the screw -up, threaded column, locating rod, spacing post etc. Component can be quickly assembled and disassembled to branch plate, and then can be in time to motor main part, branch plate one side part overhaul, can also reduce the difficulty of overhaul simultaneously.
