Description

Portable hair dryer

Technical Field

The utility model relates to a blowing and cleaning device, in particular to a portable blower, and belongs to the technical field of tools.

Background

The utility model provides a portable hair-dryer is cleaning device for places such as garden commonly used, and its typical structure is disclosed by the chinese patent of application number 201310107859.8, including a casing, a letter way subassembly and a blowing pipe of being connected with the letter way subassembly that holds in the casing, the letter way subassembly includes the letter way that links to each other with the casing and installs motor and the fan in the letter way, be provided with the supporting ring that holds the motor on the letter way, be provided with a plurality of wind-guiding muscle of diverging form between letter way and the supporting ring, and at least one be provided with the passageway that the power supply motor wire passed on the wind-guiding muscle. According to the technical scheme, the motor wire is contained in the air guide rib, compared with the prior art that the original wire is directly exposed in the air flow, the wire is prevented from being directly exposed in the air flow, the reliability of wire positioning is improved to a certain extent, the wind resistance is reduced, and the blowing efficiency is improved. However, as the metal wire core needs to be provided with gaps for insulating the skin, the conducting wire and the threading channel, the section of the air guide rib is larger, which is not beneficial to ensuring the air flow smoothness of the blowing pipe; and the assembly requires threading of a guide wire, which is inconvenient.

Disclosure of Invention

The utility model aims at: aiming at the defects in the prior art, the portable blower is provided, which can keep the smoothness of the duct airflow to the maximum extent and is convenient to disassemble and assemble on the premise of avoiding the flexible lead from being directly exposed to the airflow.

In order to achieve the above object, the basic technical scheme of the portable blower of the utility model is as follows: the wind turbine comprises a duct and a motor shell fixed in the duct through a flow guide rib, wherein the motor shell supports a motor, and fan blades and flow guide cones are respectively arranged at two ends of the motor shell;

the motor also comprises a conductive tab formed by coating and molding the metal core, wherein the inner end of the conductive tab is electrically connected with a wiring socket of the motor, and the outer end of the conductive tab penetrates out of the bypass lead to the circuit board.

The conductive connecting sheet is a pluggable component formed by directly coating the metal core with insulating plastic, so that insulating leather is not needed, a threading gap is not needed, the sectional area is reduced to the maximum extent, the air flow smoothness of the air guide duct can be better kept, and the conductive connecting sheet can be spliced to save the trouble of threading.

The utility model is further perfected as follows: the motor shell is fixed in the duct through a plurality of guide ribs which are uniformly distributed in the circumferential direction and extend radially.

The utility model is further perfected as follows: the motor shell is fixedly connected with the end cover of the motor shell, and two ends of the internal motor are respectively supported by corresponding bearings of the shell and the end cover.

The utility model is still further perfected as follows: and a wire connecting ring with a wire connecting socket is arranged between the motor and the end cover.

The utility model is further perfected as follows: the connection socket is in fit connection with a connection elbow at the inner end of the conductive connection sheet.

The utility model is further perfected as follows: and after the outer end of the electric connection sheet passes through the duct, the electric connection sheet is led to the circuit board fixed on the main body through a lead wire during installation.

Detailed Description

Example 1

The whole structure of the portable blower of this embodiment is shown in fig. 1, and mainly comprises a control handle 2 located above a main body 1 and a blower cylinder 3 with one end extending out.

As shown in fig. 2, 3 and 4, the main body 1 includes a duct 6 in which a motor housing 11 is fixed by a plurality of guide ribs 10 uniformly distributed in the circumferential direction and extending radially. The motor shell 11 and the end cover 11-1 thereof are fixedly connected, two ends of the internal motor 11-2 are respectively supported by corresponding bearings, one end of the motor shell 11 is provided with a fan blade 7 which is coupled with the motor 11-2, and the other end is provided with a diversion cone 9 fixedly connected with the fan blade 7.

A wire loop with a wire connection socket 11-3 is arranged between the motor 11-2 and the end cover 11-1. The wiring socket 11-3 is in fit connection with the connection elbow 5-1 at the inner end of the conductive connection sheet 5, the outer end of the conductive connection sheet 5 penetrates out of the duct 6, and is led to the circuit board 8 fixed on the main body 1 during installation through the lead 4. The conductive connecting sheet 5 is formed by plastic coating of a metal core, so that the required electric connection between the motor lead and the circuit board can be realized after the connection, the structure is compact, the section is small, and the resistance to the air flow in the duct is reduced to the lowest degree.
