Examples
The embodiment provides an automatic opening and closing double-air-channel electric hair dryer, as shown in fig. 1-3, comprising an air duct 10, a handle 40; the handle 40 is arranged at the bottom of the rear part of the air duct 10 and is consistent with a conventional blower; a gear switch is arranged on the handle 40, and a control circuit is arranged in the handle; the air blowing device is arranged in the air duct 10, and the air inlet is arranged at the rear end of the air duct 10, which belongs to the basic arrangement of the electric hair drier.
The inner part of the air duct 10 close to the air outlet 11 is provided with a sealable mechanism 20. In daily life, after the hair dryer is used, the hair dryer is placed in a toilet for the convenience of use next time; for example, a hair dryer is placed in a cabinet under a sink; because the air port of the blower is in a normally open state, foreign matters such as dust, insects and the like can enter the blower from the air port frequently; particularly, insects easily enter the air opening in the active state, but are difficult to clean out due to the stiff and fixed limbs after the insects die in the hair drier; if the situation that insects exist in the air blower is not noticed, and the temperature of air blown out by the air blower is high, the air blown out by the air blower has a strand of burnt peculiar smell, so that the use experience is influenced; even some consumers may choose to re-purchase a new blower.
The source of the above problems is that in the prior art, no technical personnel propose a proper plugging treatment scheme for the air outlet of the blower; the reason may be that the blower is used daily, so that the air outlet cannot be blocked, and even if the phenomenon of insect entering occurs, how to solve the problem is not considered.
Aiming at the technical problems, the invention adopts the automatic opening and closing sealing mechanism 20, when the hair dryer is used, the sealing mechanism 20 is automatically opened, and when the hair dryer is not used, the sealing mechanism 20 is automatically closed, so that an additional sealing structure (such as a sealing cover in the prior art) is not needed, and the operation is automatic and convenient.
To achieve the above technical object, the sealable mechanism 20 is specifically configured as follows:

The power unit 23 passes through the loading chamber 21 and is connected with the flexible sheet; for pushing or pulling the flexible sheet out of or back into the loading chamber 21; the power unit 23 is connected with the inherent control switch of the hair drier through a control circuit; when the control switch is turned on, the power unit 23 makes an action of pulling back the flexible sheet to enter the loading chamber 21; when the control switch is turned off, the power unit 23 pushes out the flexible sheet; the control circuit used above is a conventional controller, and the present invention does not relate to the improvement on the program or circuit of the controller.
As shown in fig. 5, an arc-shaped eaves 50 is provided at an end of the loading chamber 21; the flexible sheet is wrapped over the rigid portion 222 and the flexible portion 221; the rigid part 222 is not deformed and is connected with the power unit 23 for realizing the telescopic movement of pushing out and pulling back the flexible sheet as a whole; the flexible portion 221 is configured to have a large deformation stress from two sides to the middle in the resident state, so that the flexible sheet needs to overcome the strain stress when being in the loading chamber 21, and the deformation stress is released when the flexible sheet extends out, so as to achieve the technical purpose that the plurality of flexible sheets are suitable for being close to each other and deformed toward the center.
When the flexible sheet extends out of the loading chamber 21, the deformation stress at the two sides causes the flexible sheet to deform and bend towards the middle, and the arc-shaped eaves 50 guide the flexible sheet to bend towards the axis direction, so that the single flexible sheet deforms as shown in fig. 5; the 4 flexible sheets are deformed in the same way, and the air port can be blocked.
The loading chamber 21 is provided with a through hole 212.
The specific structure of the loading chamber 21 includes: one end of the arc sheath body structure is open, and the other end is closed; a cavity is formed inside; the open end is provided with an arc-shaped brim 50, and the closed end 211 is provided with a through hole 212.
As shown in fig. 6 to 8, the power unit 23 includes: a motor, a transmission rod and a strip-shaped toothed plate 2321. The bar-shaped toothed plate 2321 is connected with the rigid portion 222 of the flexible sheet; the specific connection mode can be fusion connection.
The strip-shaped toothed plate 2321 is in meshed connection with the transmission rod; the transmission rod is in meshed connection with the motor through a bevel gear 311 and a plane gear; through such part connected mode for the length direction of motor is parallel with the axial of dryer 10, reduces the motor and to the hindrance in wind channel, avoids too much influence air-out windage.
Two ends of the transmission rod are respectively meshed with the two strip-shaped toothed plates 2321 through gears; a transmission rod is controlled by a motor; through the mode, the power supply of the motor to the telescopic motion of the flexible sheets is realized, the occupied space is reduced, and the air outlet wind resistance is prevented from being influenced too much.
The power unit 23 can also take other configurations: for example, the output shaft of the motor is threaded, the rigid portion 222 of the flexible sheet is provided with a threaded hole corresponding to the threads, and the pushing and pulling movements are achieved by the cooperation of the threads and the threaded hole.
The specific implementation mode is as follows:
pressing the shift switch of the handle 40 triggers the power unit 23; when the motor is started, the rotating rod is driven to rotate through the rotation of the motor output shaft, and then the bar-shaped toothed plate 2321 is driven to move towards the rear end of the air duct 10, and the flexible sheet is pulled back; in addition, an over-position switch can be arranged at a proper position, and after the over-position switch is triggered by the position of the bar-shaped toothed plate 2321, the motor stops working (in a state shown in fig. 9).
The gear switch is turned off, and the power unit 23 is triggered; starting a motor, pushing out the flexible sheets, and forming a sealing structure by 4 flexible sheets; an over-position switch can also be arranged in the forward direction of the bar-shaped toothed plate 2321, and when the over-position switch is triggered, the motor stops working (in the state shown in fig. 1).
