Abstract
Description
Technical Field
[0001] This utility model relates to the field of personal care tools, specifically a hair clipper with a waterproof mechanism. Background Technology
[0002] In the field of personal care tools, hair clippers are commonly used devices for daily hair trimming, and their ease of use and safety have always been core design considerations.
[0003] Most hair clippers on the market currently use a design with the charging port at the tail. While this structure meets basic charging needs, it poses a significant risk of water damage in actual use. Hair clippers require cleaning after use to maintain hygiene, but the charging port at the tail is either directly exposed or only protected by an added rubber plug. The fit between the rubber plug and the charging port is easily affected by frequent plugging and unplugging, leading to loosening and decreased sealing performance over time. This allows moisture during cleaning to easily seep into the device through the charging port. Since hair clippers integrate circuit boards, motors, and other precision electronic components, these components may short-circuit and burn out when exposed to water, damaging the device. Furthermore, electrical leakage due to circuit malfunctions may threaten user safety.
[0004] The conflict between this charging port design and waterproofing requirements makes it difficult for existing hair clippers to balance ease of cleaning and device safety, which urgently needs to be addressed through structural optimization. Utility Model Content
[0005] The purpose of this invention is to provide a hair clipper with a waterproof mechanism to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a hair clipper with a waterproof mechanism, comprising a hair clipper body, wherein a waterproof mechanism is installed on the top left side of the hair clipper body, and a sealing mechanism is installed on the outside of the waterproof mechanism of the hair clipper body;
[0007] The waterproof mechanism includes a placement groove, which is located on the top left side of the hair clipper body. A spring block is rotatably connected to the left side of the hair clipper body inside the placement groove. A toggle block is fixedly connected to the top center of the spring block. A spring piece is fixedly connected to the bottom of the placement groove of the hair clipper body.
[0008] Preferably, a rotating pin is fixedly connected to the left side of the pop-up block, and mounting holes are opened on both sides of the placement groove corresponding to the rotating pin. A bearing is interference-fitted in the mounting hole, and a rotating pin is interference-fitted in the inner ring of the bearing.
[0009] Preferably, the bottom center of the pop-up block has a movable groove, the spring piece is placed in the movable groove, and the top of the spring piece is fixedly connected to the inner wall of the top of the movable groove.
[0010] Preferably, a locking bead is embedded on the front side of the pop-up block on the other side of the rotating pin, and a locking pit for locking the locking bead is opened on the front side of the placement groove of the hair clipper body.
[0011] Preferably, a charging port is installed in the middle of the right side of the pop-up block. The charging port is a Type-C interface and is electrically connected to the internal circuit board of the hair clipper body.
[0012] Preferably, the sealing mechanism includes a pad, which is fixedly connected to the outside of the placement groove on the top of the hair clipper body. The pad has an installation opening in the middle, and a rubber ring is fixedly connected to the inside of the installation opening. The installation opening has the same size and specifications as the placement groove.
[0013] Compared with the prior art, this utility model provides a hair clipper with a waterproof mechanism, which has the following beneficial effects:
[0014] 1. This hair clipper features a waterproof mechanism and a concealed charging port design, solving the problem of static waterproofing. The waterproof mechanism conceals and seals the charging port, effectively preventing water seepage during cleaning. The charging port is integrated on the right side of the pop-up block. When not charging, the pop-up block, under the elastic force of the spring plate, adheres to the bottom of the placement slot, and the locking bead on its front side engages with the locking pit of the placement slot, forming a mechanical lock, completely concealing the charging port within the placement slot and isolating it from external moisture. When charging is needed, the pop-up block is flipped over by moving the lever to overcome the spring plate's elasticity, and the charging port rotates out to connect to the charger. This design replaces the traditional exposed charging port with a rubber plug structure, achieving constant waterproofing through physical concealment and solving the problems of rubber plugs easily loosening and failing to seal.
[0015] 2. This hair clipper features a waterproof mechanism and a double-sealed structure, enhancing dynamic waterproof performance. The sealing and waterproofing mechanisms work together to further improve waterproof reliability. An installation opening is located in the center of the outer pad of the placement slot. The inner rubber ring is sized to match the placement slot. When the pop-up block is retracted into the slot, its top fits tightly against the rubber ring, forming the first seal. Simultaneously, the mechanical locking structure between the pop-up block and the placement slot ensures minimal gaps, creating a second barrier. During cleaning, water is doubly blocked by the rubber ring and the mechanical contact surface, preventing it from reaching the charging port and internal circuitry through gaps in the placement slot. This completely solves the problem of water easily entering the charging port and causing device burnout in traditional designs. Attached Figure Description

[0028] The waterproof mechanism 3 includes a placement groove 34, which is located on the top left side of the hairdressing body 1. A pop-up block 31 is rotatably connected to the left side of the hairdressing body 1 inside the placement groove 34. A toggle block 32 is fixedly connected to the top center of the pop-up block 31. A spring piece 39 is fixedly connected to the bottom of the placement groove 34 of the hairdressing body 1.
[0029] The concealable charging port 37 design solves the static waterproofing problem. The waterproofing mechanism 3 conceals and seals the charging port 37, effectively preventing water seepage during cleaning. The charging port 37 is integrated into the right side of the pop-up block 31. When not charging, the pop-up block 31, under the elastic force of the spring piece 39, adheres to the bottom of the placement slot 34. Its front locking bead 33 engages with the locking pit 35 of the placement slot 34, forming a mechanical lock, completely concealing the charging port 37 within the placement slot 34 and isolating it from external moisture. When charging is needed, the pop-up block 31 is flipped over by the lever 32 to overcome the elastic force of the spring piece 39, allowing the charging port 37 to rotate out and connect to the charger. This design replaces the traditional exposed charging port 37 with a rubber plug, achieving normal waterproofing through physical concealment and solving the problems of loose rubber plugs and seal failure.
[0030] A rotating pin is fixedly connected to the left side of the pop-up block 31. Mounting holes are opened on both sides of the mounting groove 34 corresponding to the rotating pin. A bearing 36 is interference-fitted in the mounting hole, and a rotating pin is interference-fitted in the inner ring of the bearing 36.
[0031] The bottom center of the pop-up block 31 has a movable groove 38, and the spring piece 39 is placed in the movable groove 38. The top of the spring piece 39 is fixedly connected to the inner wall of the top of the movable groove 38.

[0033] A charging port 37 is installed in the middle of the right side of the pop-up block 31. The charging port 37 is a Type-C interface and is electrically connected to the internal circuit board of the hair clipper body 1.
[0034] Example 2
[0035] Please see Figure 1-5 Furthermore, based on Embodiment 1, the sealing mechanism 2 further includes a pad 21, which is fixedly connected to the outside of the placement groove 34 on the top of the hair clipper body 1. An installation port 23 is provided in the middle of the pad 21, and a rubber ring 22 is fixedly connected to the inside of the installation port 23. The installation port 23 and the placement groove 34 have the same size and specifications.
[0036] The double-sealing structure enhances dynamic waterproofing performance. The sealing mechanism 2 and the waterproofing mechanism 3 work together to further improve waterproofing reliability. An installation opening 23 is provided in the middle of the pad 21 on the outer side of the placement slot 34. The rubber ring 22 fixed on the inner side matches the size of the placement slot 34. When the pop-up block 31 is housed in the placement slot 34, the top of the pop-up block 31 fits tightly against the rubber ring 22, forming the first seal. Simultaneously, the mechanical locking structure between the pop-up block 31 and the placement slot 34 ensures that the gap between them is minimized, forming the second barrier. During cleaning, water flow is doubly blocked by the rubber ring 22 and the mechanical contact surface, preventing it from reaching the charging port 37 and internal circuitry through the gaps in the placement slot 34. This completely solves the problem of water easily entering the charging port 37 and causing equipment burnout in traditional designs.
[0037] In actual operation, when this device is in use, the concealed charging port 37 design solves the static waterproofing problem. The waterproofing mechanism 3 conceals and seals the charging port 37, effectively preventing water seepage during cleaning. The charging port 37 is integrated on the right side of the pop-up block 31. When not charging, the pop-up block 31, under the elastic force of the spring piece 39, adheres to the bottom of the placement groove 34, and its front locking bead 33 engages with the locking pit 35 of the placement groove 34, forming a mechanical lock, completely concealing the charging port 37 within the placement groove 34 and isolating it from external moisture. When charging is needed, the pop-up block 31 is flipped over by the lever 32 to overcome the elastic force of the spring piece 39, and the charging port 37 rotates out with the pop-up block 31 to connect to the charger. This design replaces the traditional exposed charging port 37 with a rubber plug, achieving normal waterproofing through physical concealment and solving the problems of loose rubber plugs and sealing failure.
[0038] The double-sealing structure enhances dynamic waterproofing performance. The sealing mechanism 2 and the waterproofing mechanism 3 work together to further improve waterproofing reliability. An installation opening 23 is provided in the middle of the pad 21 on the outer side of the placement slot 34. The rubber ring 22 fixed on the inner side matches the size of the placement slot 34. When the pop-up block 31 is housed in the placement slot 34, the top of the pop-up block 31 fits tightly against the rubber ring 22, forming the first seal. Simultaneously, the mechanical locking structure between the pop-up block 31 and the placement slot 34 ensures that the gap between them is minimized, forming the second barrier. During cleaning, water flow is doubly blocked by the rubber ring 22 and the mechanical contact surface, preventing it from reaching the charging port 37 and internal circuitry through the gaps in the placement slot 34. This completely solves the problem of water easily entering the charging port 37 and causing equipment burnout in traditional designs.
