[0035] In the description of the present utility model, unless otherwise clearly defined, terms such as "arrangement", "installation", "connection", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0036] Refer to Figures 1 to 4, the utility model discloses an easily-cleaned hair clipper, which comprises a housing 100, a fixed blade assembly 400, a blade cover 300, a moving blade assembly 600, a first elastic member 700 and a second elastic member 800. A bracket 200 and a driving mechanism are provided at the front end of the housing 100; the fixed blade assembly 400, the blade cover 300 and the moving blade assembly 600 are all arranged on the bracket 200; the first elastic member 700 is used to drive the front end of the fixed blade assembly 400 to abut against the front end of the blade cover 300 and fit with the front end of the moving blade assembly 600, the driving mechanism is used to drive the moving blade assembly 600 to reciprocate in the left-right direction, and the fixed blade assembly 400 and the moving blade assembly 600 cooperate to trim hair; the second elastic member 800 is used to drive the front end of the moving blade assembly 600 to be away from the front end of the blade cover 300 and fit with the front end of the fixed blade assembly 400 that abuts against the blade cover 300.

[0037] Under the action of the first elastic member 700 and the second elastic member 800, the front end of the fixed blade assembly 400 and the front end of the moving blade assembly 600 are in fit, the front end of the fixed blade assembly 400 abuts against the front end of the blade cover 300, and the moving blade assembly 600 is in the area surrounded by the fixed blade assembly 400 and the blade cover 300, which plays a role in protecting the moving blade assembly 600. Moreover, there is a gap between the moving blade assembly 600 and the blade cover 300 to avoid the blade cover 300 interfering with the left-right reciprocating movement of the moving blade assembly 600. The driving mechanism drives the moving blade assembly 600 to reciprocate in the left-right direction. The fixed blade assembly 400 and the moving blade assembly 600 cooperate. The moving blade assembly 600 reciprocates in the left-right direction relative to the fixed blade assembly 400, and the cutter teeth of the moving blade assembly 600 and the cutter teeth of the fixed blade assembly 400 can complete hair trimming.

[0038] Apply a force to the fixed blade assembly 400 in the direction opposite to the acting force of the first elastic member 700. The front end of the fixed blade assembly 400 will be away from the front end of the blade cover 300 and the front end of the moving blade assembly 600. Then, under the action of the second elastic member 800, the front end of the moving blade assembly 600 will be further away from the front end of the blade cover 300, so that there are relatively large gaps between the moving blade assembly 600 and the fixed blade assembly 400 and between the fixed blade assembly 400 and the blade cover 300, completing the opening of the moving blade assembly 600 and the fixed blade assembly 400, that is, opening the hair clipper, thereby facilitating the cleaning of the moving blade assembly 600, the fixed blade assembly 400 and the blade cover 300, removing residual hair and various dirt, reducing or eliminating sanitary dead corners, ultimately reducing the breeding of bacteria, improving the hygienic safety of the whole hair clipper, and facilitating the maintenance and repair of components such as the moving blade assembly 600, the fixed blade assembly 400 and the blade cover 300, and improving the service life of the hair clipper.

[0039] Refer to Figure 1 and Figure 2, in some of these embodiments, the fixed knife assembly 400 includes a fixed knife holder 410 and a fixed knife 420 disposed on the fixed knife holder 410. The fixed knife holder 410 is connected to the bracket 200 through a first hinge shaft 430. The axial direction of the first hinge shaft 430 is the left - right direction. The fixed knife 420 is connected to the bracket 200 through the fixed knife holder 410, such that both the fixed knife 420 and the fixed knife holder 410 can rotate on the bracket 200 around the first hinge shaft 430.

[0040] The first elastic member 700 is disposed between the rear ends of the bracket 200 and the fixed knife holder 410. The first elastic member 700 drives the fixed knife holder 410 to rotate around the first hinge shaft 430, so that the front end of the fixed knife 420 abuts against the front end of the knife cover 300, and the front end of the fixed knife 420 is in contact with the front end of the moving knife 620. Thus, the fixed knife 420 and the knife cover 300 enclose the moving knife 620, and the fixed knife 420 and the moving knife 620 can be used to complete hair trimming.

[0041] Refer to Figures 1 to 3 , the moving knife assembly 600 includes a moving knife holder 610 and a moving knife 620 disposed on the moving knife holder 610. The moving knife holder 610 is connected to the bracket 200 through a second hinge shaft 630. The axial direction of the second hinge shaft 630 is the left - right direction. The moving knife 620 is connected to the bracket 200 through the moving knife holder 610, such that both the moving knife 620 and the moving knife holder 610 can rotate on the bracket 200 around the second hinge shaft 630.

[0042] The second elastic member 800 is disposed between the rear ends of the bracket 200 and the moving knife holder 610. The second elastic member 800 drives the moving knife holder 610 to rotate around the second hinge shaft 630, so that the front end of the moving knife 620 is away from the front end of the knife cover 300, and the front end of the moving knife 620 is in contact with the front end of the fixed knife 420 that abuts against the knife cover 300, avoiding interference between the front end of the moving knife 620 and the front end of the knife cover 300 and ensuring the contact between the front end of the moving knife 620 and the front end of the fixed knife 420.

[0043] Refer to Figure 2, when it is necessary to open the moving knife assembly 600 and the fixed knife assembly 400, press the rear ends of the fixed knife 420 and the fixed knife holder 410. The first elastic member 700 is compressed, and the fixed knife 420 and the fixed knife holder 410 rotate in opposite directions around the first hinge shaft 430, so that the front end of the fixed knife 420 moves away from the front end of the knife cover 300 and the front end of the moving knife 620. The front end of the moving knife 620 is no longer pressed by the front end of the fixed knife 420. Under the action of the second elastic member 800, the second elastic member 800 will continue to drive the moving knife holder 610 to rotate around the second hinge shaft 630, so that the front end of the moving knife 620 moves away from the front end of the knife cover 300. Finally, a large gap is formed between the moving knife assembly 600 and the fixed knife assembly 400 and between the fixed knife assembly 400 and the knife cover 300, completing the opening of the moving knife 620 and the fixed knife 420, that is, opening the hair clipper. At this time, it is convenient and fast to clean and maintain the moving knife 620, the fixed knife 420 and the knife cover 300.

[0044] Referring to Figure 1 , in some of these embodiments, the comb teeth of the knife cover 300 are aligned with the knife teeth of the fixed knife 420 one by one, and the outer surfaces of the comb teeth of the knife cover 300 and the knife teeth of the fixed knife 420 are arc-shaped, which can reduce the risk of scratching the skin by the comb teeth of the knife cover 300 and the knife teeth of the fixed knife 420.

[0045] It can be understood that the moving knife 620 also has knife teeth. The area opposite between the knife teeth of the fixed knife 420 and the knife teeth of the moving knife 620 has sharp edges, and the surfaces of other areas of the knife teeth of the fixed knife 420 and the knife teeth of the moving knife 620 are smooth.

[0046] Referring to Figure 3 , in some of these embodiments, support plates 210 are provided at both the left and right ends of the bracket 200. The second hinge shaft 630 is connected to the bracket 200 through the two support plates 210, and the bracket 200 supports the second hinge shaft 630, the moving knife holder 610 and the moving knife 620 through the two support plates 210.

[0047] It can be imagined that mounting holes are provided at the front ends of both support plates 210. A first connection hole is provided on the moving knife holder 610. The middle section of the second hinge shaft 630 passes through the first connection hole, and both ends of the second hinge shaft 630 pass through the two mounting holes respectively. There are gaps between the moving knife holder 610 and the two support plates 210, so that the moving knife holder 610 can slide left and right on the second hinge shaft 630.

[0048] Referring to Figure 3, in some of these embodiments, first limiting grooves 220 are provided at both the left and right ends of the front side surface of the bracket 200. The rear end of the support plate 210 passes through the first limiting grooves 220. The first limiting grooves 220 function to limit the support plate 210. Avoidance areas are formed on both the left and right side surfaces of the bracket 200. The avoidance areas communicate with the rear ends of the first limiting grooves 220. The avoidance areas are used for the first fasteners 211 to pass through. The first fasteners 211 are connected to the rear end of the support plate 210 and the inner wall of the first limiting grooves 220. The first fasteners 211 function to detachably fix the rear end of the support plate 210 to the bracket 200.

[0049] The cooperation of the first limiting grooves 220 and the first fasteners 211 facilitates the positioning and installation of the support plate 210, and also facilitates the disassembly of the support plate 210, the second hinge shaft 630, and the moving tool holder 610. It can be understood that the first fasteners 211 are first screws or indicating screws. A second connection hole is provided at the rear end of the support plate 210. A threaded hole is provided on the groove wall of the first limiting groove 220. The threaded section of the first fastener 211 passes through the second connection hole and is threadedly connected to the threaded structure of the threaded hole. The large end of the first fastener 211 abuts against the support plate 210, thereby fixing the support plate 210 to the bracket 200.

[0050] Refer to Figures 3 to 5 , in some of these embodiments, the hair clipper further includes a sliding member 810. The sliding member 810 is cylindrical. The end surface of the sliding member 810 is smooth. The sliding member 810 is sleeved on one end of the second elastic member 800. One of the rear ends of the bracket 200 and the moving tool assembly 600 abuts against the other end of the second elastic member 800, and the other abuts against the end surface of the sliding member 810.

[0051] The second elastic member 800 separates the rear ends of the bracket 200 and the moving tool assembly 600 through the sliding member 810. The rotation angle of the moving tool assembly 600 is limited. It can be understood that the moving tool assembly 600 undergoes a swinging motion. Since the end surface of the sliding member 810 is smooth, the friction between the sliding member 810 and the rear end of the bracket 200 or the moving tool assembly 600 can be reduced. Furthermore, the wear of the bracket 200 or the moving tool assembly 600 can be reduced, and the two ends of the second elastic member 800 can be prevented from being stuck on the bracket 200 and the moving tool assembly 600 respectively, thereby ensuring that the moving tool assembly 600 can swing smoothly.

[0052] Refer to Figure 5, in some of these embodiments, a second limiting groove 611 is provided at the rear end of the bracket 200 or the moving cutter assembly 600. A plurality of first ribs 612 are provided on the side wall of the second limiting groove 611. A plurality of second ribs 811 are provided on the outer surface of the sliding member 810. A guiding groove for guiding the first ribs 612 is formed between two adjacent second ribs 811. The arrangement and cooperation of the first ribs 612 and the second ribs 811 enable the sliding member 810 to move only along the guiding direction of the first ribs 612, that is, along the depth direction of the second limiting groove 611. When the sliding member 810 moves away from the bottom of the second limiting groove 611, the included angle between the sliding member 810 and the rear end of the moving cutter assembly 600 or the bracket 200 with which it abuts changes, so that different regions of the end face of the sliding member 810 abut against the rear end of the moving cutter assembly 600 or the bracket 200.

[0053] It can be understood that the second elastic member 800 is a second spring. In this embodiment, a second limiting groove 611 is provided at the rear end of the moving cutter holder 610 of the moving cutter assembly 600. The sliding member 810 is sleeved on one end of the second elastic member 800. The other end of the second elastic member 800 passes through the second limiting groove 611, and the end face of the sliding member 810 abuts against the bracket 200.

[0054] Refer to Figure 4 , in some of these embodiments, the driving mechanism includes a rotary driving mechanism 500 and an eccentric shaft 510 provided at the output end of the rotary driving mechanism 500. An eccentric groove 613 is formed in the rear end face of the moving cutter assembly 600. The eccentric shaft 510 passes through the eccentric groove 613 and abuts against the left and right inner groove walls of the eccentric groove 613. The rotary driving mechanism 500 drives the eccentric shaft 510 to rotate, and the eccentric shaft 510 abuts against the left and right inner groove walls of the eccentric groove 613 back and forth, thereby realizing driving the moving cutter assembly 600 to reciprocate left and right.

[0055] In some of these embodiments, a receiving cavity is provided in the housing 100. A power source and a rotary driving mechanism 500 are provided in the receiving cavity. The power source is electrically connected to the rotary driving mechanism 500 through a wire. A switch is provided on the wire. When the switch is turned on, the power source supplies power to the rotary driving mechanism 500 through the wire, and the output end of the rotary driving mechanism 500 rotates. An avoidance hole for the output end of the rotary driving mechanism 500 to pass through is provided on the bracket 200, so that the output end of the rotary driving mechanism 500 can be connected to and drive the eccentric shaft 510 to rotate.

[0056] Refer to Figure 4 and Figure 5, specifically, the eccentric groove 613 is provided in the middle of the rear end of the moving tool holder 610. The notch of the eccentric groove 613 is opened on the rear end face of the moving tool holder 610. The eccentric groove 613 penetrates the upper and lower surfaces of the moving tool holder 610. The diameter of the eccentric shaft 510 matches the width of the eccentric groove 613 in the left-right direction. The eccentric shaft 510 extends into the eccentric groove 613 from the notch of the eccentric groove 613.

[0057] It should be understood that the rotary drive mechanism 500 is a motor. An end cover is provided on the rear end face of the housing 100, and the end cover seals the rear end of the storage cavity. The switch is fixed on the end cover. The power supply can be a battery. The number of wires is two.
