Description

Technical Field

[0001] This utility model relates to an electric hair trimmer, specifically a multi-functional hair trimmer that can trim sideburns, beard, eyebrows, ear hair, and nose hair. Background Technology

[0002] Currently, most hair trimmers on the market have limited functions. Some can only trim external hair such as sideburns, beards, and eyebrows, while others can only be inserted into ear canals and nostrils to trim internal hair such as ear hair and nose hair.

[0003] A multi-functional trimmer, disclosed by the Chinese Patent Office on July 29, 2022, with patent number 202220972929.0, includes a handle, a nose hair trimmer head, and an eyebrow trimmer head. The handle houses a battery, a control board, and a motor, and has a push-button switch on its outer surface. The control board is connected to the battery, motor, and push-button switch via wires. The motor's connecting shaft has a connector with a locking block. The handle has a guide groove and a limiting groove at the corresponding location of the connector. The connecting ends of the nose hair trimmer head and eyebrow trimmer head each have a cross-shaped locking groove and a locking block. The nose hair trimmer head or eyebrow trimmer head is fixedly connected by the locking groove and locking block, and the limiting groove and locking block. The tail of the handle has a battery cover with a locking block and a limiting block. The handle has a locking groove and a limiting groove. The battery cover is fixedly connected to the handle by the locking block and locking groove, and the limiting block and limiting groove. This structure achieves its diverse functions simply by changing the nose hair trimmer head and eyebrow trimmer head, making it rather cumbersome to operate. Summary of the Invention

[0004] The purpose of this utility model is to address the defects and shortcomings of the existing technology mentioned above, and to provide people with a multifunctional hair trimmer that can trim sideburns, beard, eyebrows, ear hair, and nose hair.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This multifunctional electric hair trimmer includes a housing, a motor is installed inside the housing, and a blade head is installed at the front end of the housing. The blade head includes a cylindrical guide post, and elongated blade grooves are opened on both sides of the guide post. Fixed blades are fixedly installed in the blade grooves, and movable blades are also installed inside the guide post. The movable blades can be driven by the motor to reciprocate back and forth. Cutting teeth are provided on the outer side of both the movable blades and the fixed blades. The movable blades move back and forth, so that the cutting teeth of the movable blades and the cutting teeth of the fixed blades intersect to cut the hair. A guide head is provided at the front end of the guide post, and the guide head wraps around the front end of the fixed blades and the movable blades.

[0006] The output end of the motor is provided with an eccentric rotating shaft, and an adapter is hinged inside the housing. The front end of the adapter is engaged with the moving blade, and the rear end of the adapter is provided with two opposing shoulders. The front end of the eccentric rotating shaft is inserted between the two shoulders. When the motor drives the eccentric rotating shaft to rotate, it can abut against the two shoulders in turn, causing the adapter to swing and drive the moving blade to reciprocate back and forth.

[0007] The cutting head is inclined to the housing, and the included angle between the cutting head and the housing ranges from 150 degrees to 175 degrees.

[0008] The distance from the outer end of the shearing teeth of the fixed blade and the moving blade to the central axis of the guide post is less than the radius of the guide post.

[0009] The guide head has a rounded edge transition.

[0010] This utility model's blade can be used horizontally to trim sideburns, beards, and eyebrows. The blade can also be inserted into ear canals and nostrils to trim ear hair and nose hair. The guide head is wrapped around the front ends of the fixed blade and the moving blade, so the blades will not come into contact with the skin. The sticking hair can be cut off by the blades. It has the advantages of simple structure, safety and reliability, multiple functions, and high trimming efficiency, and has a good market prospect. Attached Figure Description

[0015] like Figure 1 , Figure 2 As shown, this utility model is a multifunctional electric hair trimmer, which includes a housing 30, a motor is installed inside the housing 30, a blade head 10 is installed at the front end of the housing 30, a battery box 32 is installed at the rear of the housing 30, which is used to power the motor after the battery is installed, and a switch 31 is installed on the housing 30 to control the start and stop of the motor.

[0016] The blade head 10 includes a cylindrical guide post 12. Elongated blade grooves 13 are formed on both sides of the guide post 12. A fixed blade 21 is fixedly installed within the blade grooves 13. A movable blade 20 is also installed within the guide post 12, also located within the blade grooves 13, and is driven by a motor to reciprocate. Shearing teeth are provided on the outer sides of both the movable blade 20 and the fixed blade 21. The movable blade 20 moves back and forth, causing its shearing teeth to intersect with those of the fixed blade 21, thus shearing the hair. Therefore, when the blade head 10 is used laterally, it can trim sideburns, beards, eyebrows, and other external hair. A guide head 11 is provided at the front end of the guide post 12. The guide head 11 wraps around the front ends of the fixed blade 21 and the movable blade 20. The distance from the outer ends of the shearing teeth of the fixed blade 21 and the movable blade 20 to the central axis of the guide post 12 is less than the radius of the guide post 12. Therefore, when the blade 10 is inserted into the ear canal or nostril to trim ear and nose hairs, the blade will not come into contact with the skin. After rotating the blade 10, the hair sticking up inside the ear canal or nostril can be cut off. The guide head 11 has a rounded edge to prevent it from touching the skin and causing discomfort.

[0017] The blade 10 is inclined to the housing 30, and the included angle between the blade 10 and the housing 30 ranges from 150 degrees to 175 degrees. The inclined arrangement of the blade 10 and the housing 30 makes it more comfortable to hold when the blade 10 is used horizontally or inserted into the ear canal or nostril.

[0018] like Figure 3 , Figure 4 As shown, the output end of the motor is provided with an eccentric rotating shaft 50, and an adapter 40 is hinged inside the housing 30. A latch 41 is provided at the front end of the adapter 40, and a slot 22 is provided at the rear end of the moving blade 20. After the latch 41 and the slot 22 are engaged, the rotation of the adapter 40 can drive the moving blade 20 to move back and forth. Two opposing shoulders 42 are provided at the rear end of the adapter 40. The front end of the eccentric rotating shaft 50 is inserted between the two shoulders 42. When the motor drives the eccentric rotating shaft 50 to rotate, it can successively abut against the two shoulders 42, causing the adapter 40 to swing and driving the moving blade 20 to reciprocate back and forth.

[0019] The blade 10 of this utility model can be used horizontally to trim sideburns, beards, and eyebrows. The blade 10 can also be inserted into the ear canal and nostril to trim ear hair and nose hair. The guide head 11 is wrapped around the front end of the fixed blade 21 and the moving blade 20. The blades will not come into contact with the skin, and the sticking hair can be cut off by the blades. It has the advantages of simple structure, safety and reliability, multiple functions and high trimming efficiency, and has good market prospects.
