Description

Blower barrel body capable of being buckled front and back by utilizing PCB support

Technical Field

The utility model relates to a bladeless blower, in particular to a blower barrel which is easy to assemble, and the fastening structure is used for replacing bonding and welding through the inner structure of the barrel body so as to simplify the assembly process and the difficulty and improve the assembly efficiency and the maintainability of the blower.

Background

The blower is used as a common household appliance, is widely used and has huge production quantity every year. As a product upgrade, the current bladeless high-speed blower has become the main stream of the industry, and the market ratio is higher and higher. Compared with the traditional blower, the structure of the bladeless high-speed blower is obviously different, specifically, the traditional bladeless high-speed blower is not truly bladeless, but a blower which is traditionally positioned in a blower cylinder body is moved to a handle and replaced by a high-speed blower and a turbofan blade, and a PCB control board responsible for heating and temperature control is positioned in the blower cylinder body, and the composition and the structure of the upper cylinder body are different from those of the traditional blower due to the structural change. The upper cylinder body of the existing bladeless high-speed blower is at least composed of a cylinder body, a PCB support and a tail cover, wherein the PCB support and the tail cover are fixed by using screws and bonding at present, a screw column is required to be preset in the cylinder body due to the fact that the bolts are fixed, the complexity of the internal structure of the cylinder body is increased, and because the space of the cylinder body is small, the operations of aligning and locking are required to be troublesome when the screws are arranged, the production difficulty is increased, and the problems that the bonding position is not correct and the later maintenance and processing are not easy to occur when the bonding is fixed are solved.

In view of the foregoing, there remains room and a need for improvements in the connection structure of the barrels of current hair dryers.
