Description

Technical Field

[0001] This application relates to the field of electric clipper technology, and in particular to an adjustable limit comb electric clipper. Background Technology

[0002] Electric hair clippers are a type of electric hair-cutting tool that uses an electric motor to drive the blades to trim hair. They are one of the most commonly used hair-shaving devices in the hairdressing industry and at home, and are characterized by high efficiency, ease of operation, and good safety.

[0003] During haircuts, it's common practice to install guide combs at the blades of electric clippers to help the hairdresser control the cutting length. However, current electric clippers typically require changing guide combs of different lengths to control different cutting lengths, which is inconvenient for actual haircutting work. Therefore, further improvements are warranted. Utility Model Content

[0004] To facilitate haircutting work when different haircut lengths are required, this application provides an adjustable limit comb electric clipper.

[0005] The adjustable limit comb electric clipper provided in this application adopts the following technical solution: An adjustable limiting comb electric hair clipper includes a housing, an inner core assembly installed inside the housing, a blade head installed at the head of the inner core assembly, and a limiting comb installed at the blade head position. A knob is installed inside the housing and is rotatably fitted onto the inner core assembly. The housing has a dial formed at the knob position for the user to rotate the knob. A first connecting mechanism is installed between the knob and the limiting comb. When the knob is rotated in either direction, the limiting comb can be moved outward or inward in the forward / backward direction via the first connecting mechanism. A second connecting mechanism is also provided between the knob and the inner core assembly. During knob rotation, the second connecting mechanism can elastically limit and lock the movement at a certain angle after each rotation.

[0006] By adopting the above technical solution, using the first connecting mechanism and the second connecting mechanism, when the knob is rotated in the forward and reverse directions, the first connecting mechanism can drive the limiting comb to move outward or inward in the forward and backward direction for adjustment, thereby adjusting the distance between the limiting comb and the blade head to control different haircut lengths, so as to realize the adjustability of the limiting comb and facilitate actual haircutting work.

[0007] Optionally, the first connecting mechanism includes an intermediate connector, which is installed inside the housing and slidably mounted on the inner core assembly in the front-back direction. A connecting portion is formed inside the limiting comb, and the front end of the intermediate connector is connected to the connecting portion. The rear end of the intermediate connector is inserted into a knob, and a spiral groove is formed on the inner wall of the knob. A sliding post is formed on the intermediate connector, and the sliding post is slidably inserted into the spiral groove.

[0008] By adopting the above technical solution, when the knob is rotated, the knob drives the intermediate connecting piece to move back and forth through the spiral groove and the sliding column, and then drives the limiting comb to move back and forth for adjustment through the connecting part.

[0009] Optionally, the inner core assembly is formed with a first slide rail extending in the front-rear direction, and the intermediate connector is formed with a first slide groove, the first slide groove being slidably connected to the first slide rail.

[0010] By adopting the above technical solution, the intermediate connector is slidably installed on the inner core assembly by utilizing the sliding fit connection between the first slide groove and the first slide rail, so that the intermediate connector can slide on the inner core assembly in the front-back direction.

[0011] Optionally, the inner core assembly is formed with a second slide rail extending in the front-rear direction, and the connecting part is formed with a second slide groove, the second slide groove being slidably connected to the second slide rail.

[0012] By adopting the above technical solution, the limiting comb is slidably installed on the inner core assembly by utilizing the sliding fit connection between the second slide groove and the second slide rail, so as to further improve the stability and smoothness of the limiting comb when it moves forward or backward for adjustment.

[0013] Optionally, the end of the connecting part is formed with a bayonet, and the intermediate connecting member is formed with a buckle. The intermediate connecting member is connected to the connecting part through the buckle and the bayonet, and the buckle and the bayonet are elastically engaged.

[0014] By adopting the above technical solution, the elastic snap-fit ​​between the buckle and the bayonet allows for a detachable connection between the limiting comb and the intermediate connecting piece, enabling the limiting comb to be installed, disassembled, and replaced.

[0015] Optionally, the second connecting mechanism includes a top post mounted on the inner core assembly; a wave guide rail extending circumferentially is formed on the bottom of the inner wall of the knob, the wave guide rail being located below the spiral groove; a top post mounting portion is formed on the inner core assembly, a mounting opening is formed in the top post mounting portion, the top post is telescopically slidably mounted in the mounting opening, the top post is aligned radially with the wave guide rail in the knob; a return spring is installed in the top post mounting portion, the top post elastically abuts against the wave guide rail in the knob under the control of the return spring, and the end of the top post slides in cooperation with the wave guide rail.

[0016] By employing the above technical solution, and utilizing the cooperation between the top post and the wave guide rail, the end of the top post remains elastically pressed against the wave guide rail during the rotation of the knob, resulting in a corresponding undulating movement. During this process, when the end of the top post enters a trough of the wave guide rail and the knob is no longer rotated, it elastically locks itself under the action of the return spring through the cooperation between the top post and the wave guide rail. That is, the top post can elastically lock itself at each trough of the wave guide rail. Therefore, during the rotation of the knob, elastic limit locking can be achieved at each certain angle, thus realizing the position adjustment of the limit comb.

[0017] Optionally, the dial includes an upper dial and a lower dial, and the upper dial and the lower dial are arranged opposite to each other.

[0018] By adopting the above technical solution, when rotating the knob, the upper and lower dials can be used to pinch the knob for rotation, which helps the user to exert more force to turn the knob.

[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. By utilizing the first and second connecting mechanisms, when the knob is rotated in the forward and reverse directions, the first connecting mechanism can drive the limiting comb to move outward or inward in the forward and backward direction for adjustment, thereby adjusting the distance between the limiting comb and the blade head to control different haircut lengths, so as to realize the adjustability of the limiting comb and facilitate actual haircutting work. 2. When the knob is rotated, the knob drives the intermediate connecting piece to move back and forth through the spiral groove and the sliding column, and then drives the limiting comb to move back and forth through the connecting part for adjustment; 3. Utilizing the cooperation between the top post and the wave guide rail, the end of the top post remains elastically pressed against the wave guide rail during knob rotation, resulting in a corresponding undulating movement. During this process, when the end of the top post enters a trough of the wave guide rail and the knob stops rotating, it elastically locks itself under the action of the return spring through the cooperation between the top post and the wave guide rail. That is, the top post can elastically lock itself at each trough of the wave guide rail. Therefore, during knob rotation, elastic limit locking can be achieved at each certain angle, thus adjusting the position of the limit comb. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0025] This application discloses an adjustable limit comb electric clipper.

[0026] Reference Figure 1 and Figure 2An adjustable limiting comb electric hair clipper includes a housing 1, an inner core assembly 2 installed inside the housing 1, a blade head 3 installed at the head of the inner core assembly 2, and a limiting comb 4 installed at the position of the blade head 3. A knob 5 is installed inside the housing 1 and is rotatably fitted onto the middle of the inner core assembly 2. The housing 1 has a dial formed at the knob 5 position for the user to rotate the knob 5. A first connecting mechanism is installed between the knob 5 and the limiting comb 4, and a second connecting mechanism is also provided between the knob 5 and the inner core assembly 2. When the knob 5 is rotated in either direction, the first connecting mechanism can drive the limiting comb 4 to move outward or inward in the front-back direction for adjustment. During the rotation of the knob 5, the second connecting mechanism can elastically limit and lock the movement at a certain angle after each rotation.

[0027] In this embodiment, the outer casing 1 has limiting parts formed at both the front and rear positions of the knob 5 to restrict the forward and backward movement of the knob 5.

[0028] Reference Figure 1 In this embodiment, the dial includes an upper dial 61 and a lower dial 62, which are arranged opposite to each other. When rotating the dial 5, the upper dial 61 and the lower dial 62 can be used to pinch the dial 5 for rotation, which helps the user to exert more force to turn the dial 5.

[0029] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the first connecting mechanism includes an intermediate connector 71, which is installed inside the outer casing 1 and slidably mounted on the inner core assembly 2 in the front-back direction. A connecting portion 72 is formed inside the limiting comb 4, and the front end of the intermediate connector 71 is connected to the connecting portion 72. The rear end of the intermediate connector 71 is inserted into the knob 5. A spiral groove 73 is formed on the inner wall of the knob 5, and a sliding post 74 is formed on the intermediate connector 71. The sliding post 74 is slidably inserted into the spiral groove 73. When the knob 5 is rotated, the knob 5 drives the intermediate connector 71 to move back and forth through the spiral groove 73 and the sliding post 74, thereby driving the limiting comb 4 to move back and forth for adjustment through the connecting portion 72.

[0030] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the top of the inner core assembly 2 is formed with two first slide rails 75 extending in the front-back direction, and these first slide rails 75 are arranged parallel to each other. Correspondingly, the front end of the intermediate connector 71, which is formed with a first slide groove 76, has two first slide grooves 76, and the first slide grooves 76 are slidably connected to the first slide rails 75 in a one-to-one correspondence, so as to slide the intermediate connector 71 onto the inner core assembly 2, allowing the intermediate connector 71 to slide on the inner core assembly 2 in the front-back direction.

[0031] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the connecting portion 72 is arranged on the left and right sides. The inner core assembly 2 has second slide rails 77 extending in the front-back direction formed on both the left and right sides. Correspondingly, the connecting portion 72 has a second slide groove 78 formed, which slidably engages with the second slide rail 77 on the corresponding side to slide the limiting comb 4 onto the inner core assembly 2, thereby further improving the stability and smoothness of the limiting comb 4 during forward or backward adjustment.

[0032] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the intermediate connector 71 and the connecting part 72 are connected by a detachable snap-fit ​​connection. The connecting part 72 has a latch 79 formed at its end, and the intermediate connector 71 has a snap-fit ​​part 710 formed on it. The intermediate connector 71 is connected to the connecting part 72 via the snap-fit ​​part 710 and the latch 79, and the snap-fit ​​part 710 and the latch 79 are elastically engaged. This elastic engagement between the snap-fit ​​part 710 and the latch 79 allows for a detachable connection between the limiting comb 4 and the intermediate connector 71, facilitating the installation, removal, and replacement of the limiting comb 4.

[0033] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the second connecting mechanism includes a top post 81 mounted on the inner core assembly 2; a wave guide rail 82 extending circumferentially is formed on the bottom of the inner wall of the knob 5, and the wave guide rail 82 is located below the spiral groove 73; a top post mounting part 83 is formed on the inner core assembly 2, and a mounting opening is formed in the top post mounting part 83, and the top post 81 is telescopically slidably mounted in the mounting opening, and the top post 81 is aligned radially with the wave guide rail 82 in the knob 5; a return spring is installed in the top post mounting part 83, and the top post 81 elastically abuts against the wave guide rail 82 in the knob 5 under the control of the return spring, and the end of the top post 81 is rounded and slides with the wave guide rail 82.

[0034] By utilizing the cooperation between the top post 81 and the wave guide rail 82, the end of the top post 81 remains elastically pressed against the wave guide rail 82 during the rotation of the knob 5, resulting in a corresponding undulating movement. During this process, when the end of the top post 81 enters the trough of the wave guide rail 82 and the knob 5 is no longer rotated, it elastically locks itself under the action of the return spring through the cooperation between the top post 81 and the wave guide rail 82. That is, the top post 81 can elastically lock itself at each trough of the wave guide rail 82. Therefore, during the rotation of the knob 5, elastic limit locking can be achieved at each certain angle, thereby adjusting the position of the limit comb 4.

[0035] The implementation principle of an adjustable limit comb electric clipper according to an embodiment of this application is as follows: When the knob 5 is rotated, the knob 5 drives the intermediate connecting piece 71 to move back and forth through the spiral groove 73 and the sliding column 74. In turn, the connecting part 72 in the limiting comb 4 drives the limiting comb 4 to move back and forth for adjustment. This adjusts the distance between the limiting comb 4 and the blade 3 to control different haircut lengths, thereby achieving the adjustability of the limiting comb 4 and facilitating actual haircutting work.

[0036] Simultaneously, during the rotation of knob 5, the end of the top post 81 remains elastically pressed against the wave guide rail 82, resulting in a corresponding undulating movement. During this process, when the end of the top post 81 enters the trough of the wave guide rail 82 and knob 5 is no longer rotated, it elastically locks itself under the action of the return spring through the cooperation between the top post 81 and the wave guide rail 82. That is, the top post 81 can elastically lock itself at each trough of the wave guide rail 82. Therefore, during the rotation of knob 5, elastic limit locking can be achieved at each certain angle, thereby adjusting the position of the limit comb 4.
