Description

Technical Field

[0001] The invention relates to the technical field of hairdressing tools, in particular to an electric hair clipper with a hair removing function. Background Art

[0002] An electric hair clipper is a commonly used tool for trimming hair or animal hair. It is well known and common to people. The structure of the electric hair clipper mainly includes a shell, a motor and a power supply assembly are arranged in the shell, a cutter head assembly is arranged at the front end of the shell, and the motor drives the cutter head assembly to move to realize the hair trimming process.

[0003] Since there is a gap area between the front end of the shell of the electric hair clipper and the cutter head assembly, during the haircutting process, hair often enters the front end of the shell from the gap area and passes into the shell from the front end. In the prior art, it is usually necessary to clean it regularly after using it for a period of time. When cleaning, the cutter head assembly must be removed from the shell to remove the hair. This results in troublesome operation and inconvenience in use. In addition, the cutter head assembly may become loose if it is frequently disassembled and assembled. Summary of the invention

[0004] The purpose of the present invention is to provide an electric hair clipper with hair removal function, which has the effects of automatic cleaning and convenient operation and use.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: an electric hair clipper with a hair removal function, comprising a housing, a cutter head assembly is arranged at the front end of the housing, a gap connected to the inner cavity of the housing is formed between the cutter head assembly and the housing, and a first driving member for driving the cutter head assembly to move is also arranged in the housing.

[0006] A second driving member and an exhaust assembly are also provided in the shell. The exhaust assembly includes a tympanic membrane driving frame, a tympanic membrane and a cylinder body. The second driving member is transmission-connected to the tympanic membrane driving frame. The tympanic membrane is mounted on the cylinder body. A chamber is formed between the tympanic membrane and the cylinder body. The tympanic membrane cooperates with the tympanic membrane driving frame. The second driving member drives the tympanic membrane to vibrate through the tympanic membrane driving frame. The tympanic membrane is provided with an air intake port connected to the chamber, the cylinder body is provided with an air outlet connected to the chamber, and an air pipe is provided in the shell. One end of the air pipe is connected to the air outlet, and the other end of the air pipe is correspondingly arranged in the gap.

[0007] By adopting the above technical solution, during the process of trimming hair, the first driving member and the second driving member are turned on at the same time, the first driving member drives the cutter head assembly to trim, and the second driving member drives the eardrum driving frame to rotate. During the rotation of the eardrum driving frame, the eardrum is vibrated by the agitation of the agitation assembly. During the vibration of the eardrum, a pressure difference is formed on both sides of the eardrum, and the external gas of the cylinder body is sucked into the cylinder body through the air intake port and discharged from the air pipe to the gap, so that the hair that falls into the gap after the cutter head assembly trims can be blown out of the gap, thereby achieving the effect of automatically cleaning the hair, and the operation and use are convenient.

[0008] The present invention is further configured as follows: the second driving member drives the eardrum driving frame to rotate, a plurality of protrusions are evenly distributed along the circumferential direction on the end surface of the eardrum, and the eardrum driving frame is provided with protruding columns corresponding to the protruding points. When the second driving component drives the eardrum driving frame to rotate, the protruding columns intermittently conflict with the protruding points.

[0009] By adopting the above technical solution, when the eardrum driving frame rotates, the convex column on it is driven to rotate, and the convex column cooperates with the convex point on the eardrum to make the eardrum vibrate. When the convex column and the convex point collide with each other, the gas in the cylinder body can be discharged from the air outlet to the trachea. Since the cylinder body is in a negative pressure state after discharging the gas, when the convex column is away from the convex point, the external gas can be sucked into the cylinder body through the air intake port.

[0010] The present invention is further configured as follows: a fan blade is arranged on the tympanic membrane driving frame, and when the tympanic membrane driving frame rotates, the fan blade generates wind pressure moving toward the air inlet.

[0011] By adopting the above technical solution, when the eardrum driving frame rotates, the fan blades are driven to rotate together, and the fan blades can have the effect of sucking air, gathering the external wind at the air suction port, the wind pressure is greater, and the hair removal effect on the cutter head assembly is better.

[0012] The present invention is further configured as follows: the first driving member is configured as a first motor, and the second driving member is configured as a second motor.

[0013] The present invention is further configured as follows: the first driving member and the second driving member are combined into one to form a dual-axis motor, a first output end of the dual-axis motor is drivingly connected to the cutter head assembly, and a second output end of the dual-axis motor is drivingly connected to the tympanic membrane driving frame.

[0014] By adopting the above technical solution, the first driving member and the second driving member are replaced by a dual-axis motor. In this way, when the dual-axis motor is started, the hair repair and cleaning processes can be achieved simultaneously. In addition, the two-in-one method can make the internal structure of the shell more compact and the overall size smaller.

[0015] The present invention is further configured as follows: the shell includes an upper shell and a lower shell, a frame is fixedly installed in the lower shell, a cylinder mounting frame is arranged in the frame, the dual-axis motor is installed in the frame, the exhaust assembly is installed in the cylinder mounting frame, an air inlet is opened on the side wall of the frame, and a vent is opened on the cylinder mounting frame.

[0016] By adopting the above technical solution, when the tympanic membrane driving frame rotates, external air flow can enter the frame from the air inlet, then enter the cylinder mounting frame from the vent, and then enter the cylinder through the air intake port.

[0017] The present invention is further configured as follows: one end of the air pipe away from the air outlet is arranged horizontally along the gap, and a plurality of blowing holes are opened on the side wall of the air pipe corresponding to the gap.

[0018] By adopting the above technical solution, a plurality of blowing holes are horizontally arranged along the gap, so that the hair cleaning effect is better.

[0019] The present invention is further configured as follows: a through hole corresponding to the air inlet is opened at the center of the eardrum drive frame.

[0020] By adopting the above technical solution, a through hole corresponding to the air inlet is arranged at the center of the eardrum drive frame, which has a better convergence effect on the airflow.

[0021] The present invention is further configured as follows: a transmission assembly is arranged between the dual-axis motor and the eardrum driving frame, the transmission assembly includes a driving gear arranged at the second output end, and a speed gear meshing with the driving gear, and a driven gear is coaxially arranged on the eardrum driving frame, and the driven gear meshes with the speed gear.

[0022] By adopting the above technical solution, when the dual-axis motor is started, the second output end drives the driving gear to rotate, and then drives the driven gear to rotate through the speed gear, so that the eardrum drive frame can be driven to rotate.

[0023] The present invention is further configured as follows: a fixing plate is provided in the shell, a fixing bracket is provided on the fixing plate, a limiting hole is provided on the fixing bracket, and the limiting hole cooperates with the air pipe limiting hole.

[0024] By adopting the above technical solution, the fixed bracket can play a better limiting role on the trachea, preventing the trachea from moving due to the internal airflow.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The second driving member drives the eardrum driving frame to rotate. The eardrum driving frame drives the eardrum to vibrate relative to the cylinder body through the agitation component, so that a pressure difference is formed inside and outside the cylinder body, and the gas outside the cylinder body can be sucked into the cylinder body through the air inlet and discharged from the air pipe to the gap, so that the hair that falls into the gap after the cutter head assembly is trimmed can be blown out of the gap, achieving the effect of automatically cleaning the hair, and the operation and use are more convenient;

[0027] 2. A plurality of fan blades are arranged on the tympanic membrane drive frame. When the tympanic membrane drive frame rotates, the external wind can be gathered at the air inlet, the wind pressure is greater, and the hair removal effect on the cutter head assembly is better;

The rear end output shaft of the dual-axis motor 13 is driven and matched with the exhaust assembly through a transmission assembly.

[0036] like Figure 3 and Figure 4 As shown, the exhaust assembly includes a drum drive frame 6, a drum 7 and a cylinder body 8. The rear end output shaft of the dual-axis motor 13 drives the drum drive frame 6 to rotate through the transmission assembly. The drum 7 is fixedly installed on the cylinder mouth of the cylinder body 8. The drum drive frame 6 and the drum 7 are agitated and matched by an agitation assembly. The agitation assembly includes a plurality of convex columns 61 and convex points 71. The convex column 61 is set to at least one. In this embodiment, the convex column 61 is set to a plurality of convex columns 61, which are circumferentially distributed on the drum drive frame 6, and the convex points 71 are correspondingly arranged on the drum 7. The plurality of convex columns 61 and the convex points 71 are A one-to-one correspondence is set, when the dual-axis motor 13 drives the eardrum driving frame 6 to rotate, the boss 61 intermittently conflicts with the convex point 71; an air intake port 72 connected to the inner cavity of the cylinder body 8 is opened at the center of the eardrum 7, and an air outlet 81 is opened at the bottom of the cylinder body 8. An air pipe 9 is set in the shell 1, one end of the air pipe 9 is connected to the air outlet 81, and the other end of the air pipe 9 is corresponding to the gap 3. The end of the air pipe 9 corresponding to the gap 3 is horizontally set along the gap 3, and a plurality of blowing holes 91 are opened on the side wall of the air pipe 9 corresponding to the gap 3, so that the cleaning effect when blowing hair is better. An air inlet 41 is provided on the side wall of the frame 4, a vent 51 is provided on the cylinder mounting frame 5, the vent 51 is communicated with the inner cavity of the cylinder mounting frame 5, a plurality of fan blades 62 are provided on the end surface of the tympanic membrane driving frame 6 close to the tympanic membrane 7, a through hole 63 corresponding to the air intake port 72 is provided in the center of the tympanic membrane driving frame 6, and a through hole 63 corresponding to the air intake port 72 is provided in the center of the tympanic membrane driving frame 6, which has a better converging effect on the airflow.
