Description

Wiring device of handheld electric appliance
Technical Field
The invention belongs to the technical field of household appliances, and relates to a handheld electric appliance, in particular to a wiring device of the handheld electric appliance.
Background
In life, a plurality of handheld electric appliances, most typically electric hair dryers, and other electric appliances such as electric drills and hand grinders have the common characteristic that an external alternating current power supply is required, so that the electric appliances are provided with power supply connecting wires, and the electric appliances are provided with a handle through which the power supply connecting wires penetrate and extend out of the tail ends of the handles. Electric appliance is at the during operation, and its inside motor inevitably has vibrations to it rocks to drive the power connecting wire, because inside the power connecting wire wears to establish the handle, can consequently and bump the handle inner wall, the aggravation vibrations influence user's experience.
For this reason, it is conceivable to press the power cord against the inner wall of the handle with a fixture, specifically, with a door-shaped pressing piece or the like, to confine the power cord in a space formed by the pressing piece and the inner wall, and to fasten the power cord with a screw. This solution has the drawback of increasing the number of parts, while the screwing takes place inside the handle, which is not easy to operate, because of the small operating space. The more big problem lies in that when the hand-held electric appliance is used for electric blowing, the handle of the electric blowing is used as an air inlet channel, and the door-shaped pressing sheet or similar components can greatly increase the area of wind shielding and influence the air inlet flow.
Disclosure of Invention
The invention aims to overcome the technical problems and provide a more reasonable wiring device of a handheld electric appliance.
Therefore, the invention adopts the following technical scheme: termination of hand-held type electrical apparatus, including hollow handle and power cord, inside the power cord passed the handle and got into electrical apparatus, its characterized in that: a clamping ring is fixed at the tail end of the handle and is made of rigid material; the power line is in a tensioning state, a positioning part is arranged on the power line, the positioning part is made of elastic insulating materials and comprises at least two sections of convex parts and one section of concave part in the length direction of the power line, the concave part is positioned between the two sections of convex parts, and the diameter of the concave part is smaller than that of the two sections of convex parts, so that two step surfaces are formed; the snap ring is clamped on the concave part between the two step surfaces so as to limit the axial movement of the snap ring.
Furthermore, the snap ring is provided with a plurality of snap teeth which are matched with the concave part of the positioning part of the power line, so that the circumferential movement of the snap ring is limited.
Furthermore, the handheld electric appliance is a hair drier, the hollow handle is an air inlet channel of the hair drier, the clamping ring is fixed at the tail end of the handle, and an air inlet is formed in the position, close to the clamping ring, of the handle.
When the power cord is manufactured, the positioning part on the power cord is integrally formed with the power cord, namely the rubber coated outside the power cord is made of an elastic insulating material, and the positioning part can be formed through a specific die; when the handle is installed, the positioning part of the power line and the clamping ring can be installed, so that the power line is fixed at the tail end of the handle, then penetrates through the handle, and is electrically connected with other parts after being tensioned.
When the power line enters the handle, the power line is positioned in the center of the handle, and the main body part is not contacted with other parts, so that the power line can not contact other parts even when the power line shakes due to electrification; at the joint, namely the fixing position of the positioning part and the snap ring of the power line, the rigid part is connected with the elastic part, and the stress points are distributed around the circle center, so that the stress is balanced in all directions, the power line can be well buffered, the shaking of the power line is absorbed, and the operation is not influenced.
Meanwhile, under the condition that the electric hair drier is applied to the electric hair drier, the tail end of the handle is provided with the clamping ring and the positioning part of the power cord, and the electric hair drier is obviously closed; the upward part of the handle, namely the part of the handle adjacent to the snap ring, is provided with an air inlet, namely air enters the handle from the circumference of the section of the handle, 3600Air is supplied, and the air volume is larger; the handle is used as an air flow channel, and only the power line is arranged in the handle in the flow channel, so that the sectional area of the flow channel is reduced, and the influence is minimized; because the power line as the obstacle is positioned at the center of a circle, the anisotropic balance of the air flow in the handle is not changed. Meanwhile, the invention greatly reduces the number of parts and is more convenient to install.

Detailed Description
See the drawings. The embodiment is a handle 1 of the hair drier, which comprises a shell 2, a power line 3 and a large-hole filter screen 4, and forms an external frame of the hair drier. In the frame, a clamping ring 5, a small-hole filter screen 6, a motor 7 and a switch assembly 8 are arranged from back to front, wherein a part of the switch assembly 8 extends out of the shell for operation. The power line 3 is provided with a positioning part 31 which is made of the same material as the rubber of the power line and comprises two sections of convex parts with larger diameters, so that a circle of concave part with smaller diameter is formed; after the positioning part 31, there are several rings of ring pieces with gradually reduced diameter, also called fins, which have the effect of beauty and can prevent the power line from knotting.
The snap ring 5 is composed of two semi-rings, wherein a circle of convex ring 51 protruding inwards is arranged in the middle of the two semi-rings, a plurality of clamping teeth 52 are further arranged on the convex ring 51, the position of the snap ring 5 is fixed at the rearmost end of the large-hole filter screen 4 during assembly and is matched with the positioning part 31 of the power cord, and the convex ring 51 of the snap ring is clamped in the middle concave part of the positioning part 31, so that the power cord 3 is prevented from moving in the front-back direction; since the positioning portion 31 has a certain elasticity, the latch 52 on the protruding ring further "sticks" into the positioning portion 31 to make it partially elastically deformed, thereby preventing the positioning portion 31 from rotating in the circumferential direction.
The small hole filter screen 6 is arranged in front of the clamping ring 5, and the large hole filter screen 4 covers the clamping ring 5 and the small hole filter screen 6 and is clamped with the shell 2, so that all the parts are fixed into a whole. After the power line 3 extends into the shell, the power line is connected with the motor 7 and the switch assembly 8 and is in a tensioning state.
When the motor 7 is started, negative pressure is generated in the handle, and outside air enters the handle after passing through the large-hole filter screen 4 and the small-hole filter screen 6 and flows forwards by taking the handle as a flow passage.
As can be seen from the description of the embodiment, the invention has simple assembly and the small-hole filter screen can be 360 degrees0And (6) air inlet.
