Description

Technical Field

[0001] The utility model relates to an impeller structure for a blower, belonging to the technical field of blowers. Background Art

[0002] A blower is an air supply device that uses the pressure difference to make the fluid flow. The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (also oil tank), and oil drip nozzle. The blower operates eccentrically with the rotor offset in the cylinder, and the volume changes between the blades in the rotor slot to inhale, compress, and spit out the air. During operation, the pressure difference of the blower is used to automatically send lubrication to the oil drip nozzle and drip into the cylinder to reduce friction and noise, while keeping the gas in the cylinder from flowing back. This type of blower is also called a sliding vane blower.

[0003] An existing impeller structure for a blower still has some problems during use. For example, the existing impeller structure is fixedly connected to the outside of the starter, so it is troublesome to disassemble the impeller structure. In addition, a dustproof plate is installed inside the air inlet pipe of the blower cover. Dust will be adsorbed on the surface of the dustproof plate due to frequent and long-term use. When the dust needs to be cleaned, it is inconvenient to clean the dustproof plate because the dustproof plate is located inside the air inlet pipe. Utility Model Content

The impeller body inside the blower cover can be quickly disassembled and the dust adsorbed by the dustproof plate inside the air intake pipe can be easily cleaned to solve the problems raised in the above-mentioned background technology.

[0008] Furthermore, the clamping block and the fixing block are located inside the fan cover, and the impeller body is rotatably connected to the inside of the fan cover.

[0009] Furthermore, the No. 1 threaded tube is symmetrically distributed on the outside of the clamping block, and the No. 1 screw is rotatably connected to the inside of the No. 1 threaded tube through a rotating cover.
