[0026] Embodiment

[0027] As Figures 1-4As shown in the figure, this embodiment provides a hair clipper that can automatically lubricate the blade, including a housing 1. A blade assembly 2 is provided at the end of the housing 1. A motor for driving the blade assembly 2 to move is arranged inside the housing 1. Driving the blade assembly 2 to move through the motor for hair cutting belongs to the conventional technology in the prior art, and its specific structure and working principle will not be elaborated in detail here; a control board 4 and an oil injection mechanism 3 are fixedly installed inside the housing 1 by bolts. The output end of the oil injection mechanism 3 is arranged above the blade assembly 2. The control board 4 is electrically connected to the motor and the oil injection mechanism 3 respectively. The control board 4 controls the oil injection mechanism 3 or the motor to work.

[0028] Specifically, the oil injection mechanism 3 includes a fuel tank assembly 31, an oil pump 32 and an oil outlet member 35. The inside of the fuel tank assembly 31 is used to accommodate lubricating oil. An oil outlet hole 3121 is opened at the bottom of the fuel tank assembly 31. The oil outlet hole 3121 is connected to the input end of the oil pump 32 through a suction pipe 33. The output end of the oil pump 32 is connected to the input end of the oil outlet member 35 through a spray pipe 34. At least one oil injection hole 351 is opened in the oil outlet member 35. The oil injection hole 351 is arranged above the blade assembly 2. In this embodiment, the number of oil injection holes 351 is two, which are respectively located on both sides of the oil outlet member 35, so that the sprayed lubricating oil can be evenly distributed on the blade assembly 2. The oil pump 32 is electrically connected to the control board 4. The control board 4 sends an instruction to the oil pump 32. The oil pump 32 extracts the lubricating oil in the fuel tank assembly 31, discharges it from the spray pipe 34 to the oil outlet member 35 after passing through the suction pipe 33, and finally flows out from the oil injection hole 351 and drips on the blade assembly 2.

[0029] Among them, the fuel tank assembly 31 includes a fuel tank upper cover 311 and a fuel tank lower cover 312. The fuel tank upper cover 311 and the fuel tank lower cover 312 are clamped with each other and fixed by screws. The internal space after the combination of the fuel tank upper cover 311 and the fuel tank lower cover 312 is used to store lubricating oil. The oil outlet hole 3121 is arranged at the lowest position of the bottom of the fuel tank lower cover 312. An oil filling hole 3111 is opened on the surface of the fuel tank upper cover 311. An opening is provided at the position of the housing 1 corresponding to the oil filling hole 3111, which is convenient for directly injecting lubricating oil without opening the housing 1. The oil filling hole 3111 is detachably connected with an oil tank cap 36. Specifically, a connecting column 361 is integrally formed at one end of the oil tank cap 36, and a plug 362 is integrally formed at the other end. The connecting column 361 is embedded on the surface of the housing 1, and the plug 362 is embedded in the oil filling hole 3111. The oil tank cap 36 is made of rubber material and has a certain deformation ability. When refueling is required, the plug 362 is pulled out of the oil filling hole 3111 to add lubricating oil. After adding lubricating oil, the oil filling hole 3111 is blocked by the plug 362 to avoid oil leakage.

[0030] Further, the upper cover 311 of the fuel tank is provided with a vent hole 3112, the surface of the vent hole 3112 is covered with a gasket 3114, and a vent membrane 3113 is arranged between the vent hole 3112 and the gasket 3114. The vent membrane 3113 is fixed by the gasket 3114. The vent membrane 3113 can pass air to adjust the internal pressure, enabling the oil pump 32 to smoothly extract the lubricating oil inside the fuel tank assembly 31.

[0031] Further, a sealing ring groove 3122 is formed at the top end of the lower cover 312 of the fuel tank. The sealing ring groove 3122 is arranged along the top contour of the lower cover 312 of the fuel tank. A sealing ring 3123 is embedded in the sealing ring groove 3122, and the top end of the sealing ring 3123 abuts against the upper cover 311 of the fuel tank. By arranging the sealing ring 3123 at the connection between the upper cover 311 and the lower cover 312 of the fuel tank, the sealing performance of the fuel tank assembly 31 is improved, and oil leakage is avoided.

[0032] Among them, a plurality of overflow holes 37 are formed at the bottom of the housing 1. If the fuel tank assembly 31 leaks oil or overflows when injecting lubricating oil, the overflowing lubricating oil flows to the bottom of the housing 1 and then flows out from the overflow holes 37.

[0033] Further, an oil injection switch 42 is embedded at the top end of the housing 1. A switch button 41 is integrated at the position of the control board 4 corresponding to the oil injection switch 42, and the oil injection switch 42 is cooperatively connected with the switch button 41. Press the oil injection switch 42, and the oil injection switch 42 touches the switch button 41 to start the oil pump 32 to work. Press it again to stop the oil pump 32.

[0034] In one embodiment, a battery 5 is arranged inside the housing 1. A charging plug 6 is embedded at the end of the housing 1. The battery 5 is electrically connected to the control board 4, and the charging plug 6 is connected to the control board 4 through an internal wire. The battery 5 provides power for the hair clipper to work, and the battery 5 is charged by connecting a power cord to the charging plug 6.

[0035] The working principle of the present utility model: By opening the fuel tank cover 36 of the present utility model, lubricating oil is added into the fuel tank assembly 31 through the oil injection hole 3111, and then the fuel tank cover 36 is covered. When it is necessary to add lubricating oil to the cutter head assembly 2, press the oil injection switch 42. The control board 4 receives the instruction and controls the oil pump 32 to work. The oil pump 32 extracts the lubricating oil inside the fuel tank assembly 31, passes through the suction pipe 33, and then discharges it from the spray pipe 34 to the oil outlet part 35, and finally flows out from the oil injection hole 351 and drips onto the cutter head assembly 2. After adding the lubricating oil, press the oil injection switch 42 again, and the oil pump 32 stops working.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present disclosure.
