[0041] 1 to 4 , a double-blade hair clipper according to an embodiment of the present application includes:

[0042] A housing 300 , to which the first cutter head assembly 100 and the second cutter head assembly 200 are detachably connected;

[0043] The first cutter head assembly 100 includes a first fixed cutter 110 and a first movable cutter 120. The first fixed cutter 110 is located above the first movable cutter 120. A row of first cutter teeth 111 is provided at the front end of the first fixed cutter 110. A row of second cutter teeth 121 is provided at the front end of the first movable cutter 120.

[0044] The second cutter head assembly 200 includes a second fixed blade 210 and a second movable blade 220. The second movable blade 220 is located below the first movable blade 120. The second fixed blade 210 is located below the second movable blade 220. A row of third blade teeth 211 is provided at the front end of the second fixed blade 210, and a row of fourth blade teeth 221 is provided at the front end of the second movable blade 220.

[0045] The first movable knife 120 and the second movable knife 220 are both located between the first stationary knife 110 and the second stationary knife 210 , so that the first stationary knife 110 and the second stationary knife 210 cover the first movable knife 120 and the second movable knife 220 .

[0046] The reciprocating drive mechanism 400 is disposed in the housing 300. The output end of the reciprocating drive mechanism 400 is connected to the first movable blade 120, and the first movable blade 120 is transmission-connected to the second movable blade 220. The reciprocating drive mechanism 400 is used to drive the first movable blade 120 and the second movable blade 220 to reciprocate in the left and right directions to cut hair.

[0047] It is understood that the first movable blade 120 and the second movable blade 220 are both located between the first fixed blade 110 and the second fixed blade 210, so that the first fixed blade 110 and the second fixed blade 210 cover the first movable blade 120 and the second movable blade 220. The sides of the first movable blade 120 and the second movable blade 220 that face away from each other are respectively covered by the first fixed blade 110 and the second fixed blade 210. This prevents the first movable blade 120 and the second movable blade 220 from contacting the customer's skin, thereby preventing the first movable blade 120 and the second movable blade 220 from scratching the customer's skin during the haircut process, thereby improving the safety of the double-blade hair clippers during use. Furthermore, when it is necessary to clean the first and second blade head assemblies 100 and 200, the first and second blade head assemblies 100 and 200 can be removed from the housing 300, thereby improving the convenience of cleaning the double-blade hair clippers.

[0048] It is not difficult to understand that the hair will enter between the two adjacent first blade teeth 111 and the two adjacent third blade teeth 211, and then under the action of the first movable blade 120 and the second movable blade 220, the first blade teeth 111 and the second blade teeth 121 cooperate with each other, and the third blade teeth 211 and the fourth blade teeth 221 cooperate with each other, forming a scissors-like effect, thereby cutting the hair between the two adjacent first blade teeth 111 and the two adjacent third blade teeth 211, achieving a haircutting effect.

[0049] Referring to Figures 3 and 4 , a first protrusion 112 is provided at the front end of the first cutting tooth 111. The front end of the first protrusion 112 is located in front of the second cutting tooth 121. The first protrusion 112 can abut against the customer's skin to limit the first and second cutting teeth 111, 121 from abutting against the customer's skin. A second protrusion 212 is provided at the front end of the second cutting tooth 121. The front end of the second protrusion 212 is located in front of the fourth cutting tooth 221. The second protrusion 212 can abut against the customer's skin to limit the third and fourth cutting teeth 211, 221 from abutting against the customer's skin. The distance between the front ends of the first protrusion 112 and the second protrusion 212 is less than or equal to 2 mm. It can be understood that the first protrusion 112 and the second protrusion 212 are both arranged in front of the first blade tooth 111, the second blade tooth 121, the third blade tooth 211 and the fourth blade tooth 221. During the haircutting process, the first protrusion 112 and the second protrusion 212 can come into contact with the customer's skin, effectively avoiding the first blade tooth 111, the second blade tooth 121, the third blade tooth 211 and the fourth blade tooth 221 from coming into contact with the customer's skin, avoiding the first blade tooth 111, the second blade tooth 121, the third blade tooth 211 and the fourth blade tooth 221 from damaging the customer's skin, and further improving the safety of the double-blade hair clippers during use.

[0050] 3 and 4 , during a haircut, if the first protrusion 112 and the second protrusion 212 are pressed against the customer's skin, the soft skin may be deformed and enter between the first protrusion 112 and the second protrusion 212, or between two adjacent first protrusions 112 and between two adjacent second protrusions 212, which may easily cause the second blade teeth 121 on the first movable blade 120 and the fourth blade teeth 221 on the second movable blade 220 to scratch the skin between the first protrusion 112 and the second protrusion 212, or between two adjacent first protrusions 112 and between two adjacent second protrusions 212. It can be understood that the distance between the front end of the first protrusion 112 and the front end of the second protrusion 212 is less than or equal to 2 mm. The smaller gap can effectively reduce the depth of the skin entering between the first protrusion 112 and the second protrusion 212, and reduce the depth of the skin entering between two adjacent first protrusions 112 and between two adjacent second protrusions 212, thereby avoiding the second blade teeth 121 and the fourth blade teeth 221 from scratching the skin between the first protrusion 112 and the second protrusion 212, and avoiding the second blade teeth 121 and the fourth blade teeth 221 from scratching the skin between two adjacent first protrusions 112 and between two adjacent second protrusions 212, thereby further improving the safety of the double-blade hair clippers during use.

[0051] As one embodiment of the present application, the first protrusion 112 is provided with a first curved surface, which can abut against the customer's skin, and the second protrusion 212 is provided with a second curved surface, which can abut against the customer's skin. It is understood that the first protrusion 112 abuts against the customer's skin via the first curved surface, and the second protrusion 212 abuts against the customer's skin via the second curved surface. The smooth first and second curved surfaces can enhance the customer's comfort during the haircut.

[0052] 3 and 4 , a first stopper 113 is provided on the side of the first protrusion 112 adjacent to the second protrusion 212, and a second stopper 213 is provided on the side of the second protrusion 212 adjacent to the first protrusion 112. The first stopper 113 and the second stopper 213 are used to close the gap between the front end of the second cutting tooth 121 and the front end of the fourth cutting tooth 221. It will be appreciated that the first stopper 113 and the second stopper 213 can prevent skin from entering between the first protrusion 112 and the second protrusion 212, thereby reducing the depth to which skin can enter between two adjacent first protrusions 112 and two adjacent second protrusions 212, thereby preventing the second cutting tooth 121 and the fourth cutting tooth 221 from scratching the skin, further improving the safety of the double-blade hair clippers during use.

[0053] 5 to 7 , the first cutter head assembly 100 includes a first cutter holder 130 , which is connected to the first movable cutter 120 , and the second cutter head assembly 200 includes a second cutter holder 230 , which is connected to the second movable cutter 220 . The first cutter holder 130 and the second cutter holder 230 are in transmission connection with each other. The first cutter holder 130 is provided with a first transmission slot 131 , and the reciprocating drive mechanism 400 includes a rotary drive member and an eccentric rod 410 . The rotary drive member is provided within the housing 300 , and the eccentric rod 410 is provided within the first transmission slot 131 . The rotary drive member is used to drive the eccentric rod 410 to abut against the left or right wall of the first transmission slot 131 back and forth, so that the first cutter holder 130 reciprocates in the left and right directions. As one embodiment of the present application, the rotary drive member can be a motor. It is understood that the motor's output shaft is connected to the eccentric rod 410, and the motor drives the eccentric rod 410 to perform circular motion around the central axis of the motor's output shaft, causing the eccentric rod 410 to abut back and forth against the left or right side wall of the first transmission slot 131, thereby driving the first tool holder 130 to perform reciprocating motion in the left and right directions. Since the first tool holder 130 is transmission-connected to the second tool holder 230, the first tool holder 130 can drive the second tool holder 230 to perform reciprocating motion in the left and right directions. The eccentric rod 410 is always disposed within the first transmission slot 131. The length of the eccentric rod 410 is parallel to the front-to-back direction.

[0054] 5 to 7 , a transmission block 132 is provided on the first tool holder 130, and a second transmission slot 231 is defined on the second tool holder 230. The transmission block 132 is inserted into the second transmission slot 231 so that the transmission block 132 can abut against the left or right side wall of the second transmission slot 231. It is understood that when the first tool holder 130 reciprocates in the left and right directions, the transmission block 132 can abut against the left or right side wall of the second transmission slot 231, allowing the second tool holder 230 to reciprocate in the left and right directions. The cooperation between the transmission block 132 and the second transmission slot 231 realizes a transmission connection between the first tool holder 130 and the second tool holder 230.

[0055] 5 and 6 , the first cutting head assembly 100 further includes a first shell 140, which is detachably connected to the housing 300, the first blade holder 130 is slidably connected to the first shell 140 left and right, and the first fixed blade 110 is connected to the first shell 140. The second cutting head assembly 200 further includes a second shell 240, which is detachably connected to the housing 300, the second blade holder 230 is slidably connected to the second shell 240 left and right, and the second fixed blade 210 is connected to the second shell 240. As an embodiment of the present application, the first shell 140 is provided with a first long strip extending along the left and right directions, the first tool holder 130 is provided with a first slide groove extending along the left and right directions, and the first long strip is arranged in the first slide groove so that the first long strip can guide the left and right movement of the first tool holder 130; the second shell 240 is provided with a second long strip extending along the left and right directions, the second tool holder 230 is provided with a second slide groove extending along the left and right directions, and the second long strip is arranged in the second slide groove so that the second long strip can guide the left and right movement of the second tool holder 230.

[0056] 5 to 8 , a first buckle slot 310 and a second buckle slot 320 are provided on the shell 300 , a first buckle block 141 is provided on the first shell 140 , and the first buckle block 141 can be buckled into the first buckle slot 310 , and a second buckle block 241 is provided on the second shell 240 , and the second buckle block 241 can be buckled into the second buckle slot 320 . It can be understood that the first buckle block 141 can be buckled into the first buckle groove 310, and the mutual cooperation between the first buckle block 141 and the first buckle groove 310 plays a role in positioning the first shell 140, so that the first shell 140 can be correctly installed on the shell 300, and the first buckle block 141 and the first buckle groove 310 can realize the rapid installation and disassembly of the first shell 140, which is convenient for the barber to quickly install or disassemble the first blade assembly 100; the second buckle block 241 can be buckled into the second buckle groove 320, and the mutual cooperation between the second buckle block 241 and the second buckle groove 320 plays a role in positioning the second shell 240, so that the second shell 240 can be correctly installed on the shell 300, and the second buckle block 241 and the second buckle groove 320 can realize the rapid installation and disassembly of the second shell 240, which is convenient for the barber to quickly install or disassemble the second blade assembly 200, thereby improving the convenience of using the double-blade hair clippers.

[0057] 5 , 6 and 8 , an iron sheet 330 is provided on the shell 300 , a first magnetic component 142 is provided on the first shell 140 , and the first shell 140 is magnetically attracted to the iron sheet 330 through the first magnetic component 142 , and a second magnetic component 242 is provided on the second shell 240 , and the second shell 240 is magnetically attracted to the iron sheet 330 through the second magnetic component 242 . It is understandable that the first housing 140 is connected to the iron sheet 330 on the housing 300 via the first magnetic member 142. The first magnetic member 142 not only serves as a fixed connection, but also enables the first housing 140 to be quickly installed and removed, making it easier for the barber to quickly install or remove the first blade assembly 100. The second housing 240 is connected to the iron sheet 330 on the housing 300 via the second magnetic member 242. The second magnetic member 242 not only serves as a fixed connection, but also enables the second housing 240 to be quickly installed and removed, making it easier for the barber to quickly install or remove the second blade assembly 200, thereby improving the convenience of using the double-blade hair clippers. As an embodiment of the present application, the first magnetic member 142 is a first magnet, and the second magnetic member 242 is a second magnet.

[0058] 5 and 6 , the first blade head assembly 100 further includes a first blade pressing spring 150, through which the first blade holder 130 is connected to the first housing 140. The first blade pressing spring 150 is used to apply shearing pressure to the first blade holder 130. The second blade head assembly 200 further includes a second blade pressing spring 250, through which the second blade holder 230 is connected to the second housing 240. The second blade pressing spring 250 is used to apply shearing pressure to the second blade holder 230. During the circular motion of the eccentric rod 410 about the central axis of the motor output shaft, the eccentric rod 410 may disengage from the left or right side wall of the first transmission slot 131 at certain locations. At this point, the power transmitted by the eccentric rod 410 becomes uneven, and the force applied to the first blade holder 130 is interrupted, resulting in unstable power transmission to the eccentric rod 410. This not only causes vibration and noise in the double-blade hair clippers, but also shortens the service life of the eccentric rod 410.

[0059] It is understood that by providing the first blade pressing spring 150, under the action of the first blade pressing spring 150, the first blade holder 130 can move left and right, so that the left side wall or right side wall of the first transmission groove 131 on the first blade holder 130 can always maintain contact with the eccentric rod 410, thereby avoiding uneven power transmission by the eccentric rod 410. Similarly, the transmission block 132 will break away from the contact with the left side wall or right side wall of the second transmission groove 231 at certain specific positions. By providing the second blade pressing spring 250, under the action of the second blade pressing spring 250, the second blade holder 230 can move left and right, so that the left side wall or right side wall of the second transmission groove 231 on the second blade holder 230 can always maintain contact with the transmission block 132, thereby avoiding uneven power transmission by the transmission block 132, improving the quietness of the double-blade hair clippers, and extending the service life of the transmission block 132.

[0060] On the other hand, the first blade pressing spring 150 and the second blade pressing spring 250 apply shearing pressure to the first blade holder 130 and the second blade holder 230 respectively, so that the first movable blade 120 on the first blade holder 130 can obtain a stable shearing force, ensuring that the first movable blade 120 and the first fixed blade 110 maintain a consistent haircutting effect during the operation; and the second movable blade 220 on the second blade holder 230 can obtain a stable shearing force, ensuring that the second movable blade 220 and the second fixed blade 210 maintain a consistent haircutting effect during the operation.

[0061] As one embodiment of the present application, either the first blade assembly 100 or the second blade assembly 200 can be removed, allowing the double-blade hair clippers to be used as single-blade hair clippers. In this case, the gap between two adjacent second blade teeth 121 on the first movable blade 120 is smaller than the gap between two adjacent fourth blade teeth 221 on the second movable blade 220. The first movable blade 120 is used for fine cutting, while the second movable blade 220 is used for rough cutting. A handle for the barber to hold is connected to the rear end of the housing 300.

[0062] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
