Embodiment 1

[0032] As shown in FIG. 1 to FIG. 4, the embodiment relates to an electric saw guide plate capable of recycling lubricating oil, which comprises two outer guide plates 1 and an oil guide plate 2 mounted between the two outer guide plates 1. A size of the oil guide plate 2 is smaller than sizes of the outer guide plates 1, and outer edges of inner walls of the outer guide plates 1 and a periphery of the oil guide plate 2 form a guide plate groove 3 for containing a saw chain Rear ends of the outer guide plates 1 are provided with mounting grooves 11 and pin holes 12 for fixing the outer guide plates 1 on a housing on an engine portion of the chain saw. Front ends of the outer guide plates 1 are provided with positioning holes 13 for fixing the outer guide plates 1 with guide wheels. In the present application, the outer guide plates 1 and the oil guide plate 2 may also be fixed by a common method in the prior art, such as spot welding or laser welding.

[0033] In the embodiment of the present application, four oil inlets 21 are formed in an upper end of the oil guide plate 2 and four oil outlets 22 are formed in a lower end of the oil guide plate. The oil inlets 21 and the oil outlets 22 are communicated through an oil guide channel 23, and the oil inlets and the oil outlets are communicated with the guide plate groove 3 at the same time. Numbers of the oil inlets 21 and the oil outlets 22 may be set according to actual needs.

[0034] In the embodiment of the present application, the inner walls of the outer guide plates 1 are provided with oil blocking grooves 14 corresponding to the oil inlets 21, lower ends of the oil blocking grooves 14 are close to the oil inlets 21, and the oil blocking grooves 14 are obliquely and backwardly arranged along front ends of the outer guide plates 1.

[0035] The oil blocking grooves 14 are used for blocking the lubricating oil carried by the saw chain and shaken off under an inertia effect.

[0036] In the embodiment of the present application, the oil inlets 21 are connected with an oil inlet channel 24, the oil outlets 22 are connected with an oil outlet channel 25, the oil inlet channel 24 and the oil outlet channel 25 are communicated through the oil guide channel 23, and two oil inlet channels 24 located a front end of the oil guide plate 2 may be directly communicated with two oil outlet channels 24 located at the front end of the oil guide plate 2. The oil inlet channel 24 is obliquely and backwardly arranged along the front end of the oil guide plate 2, and the oil outlet channel 25 is obliquely and backwardly arranged along the front end of the oil guide plate 2. An angle between the oil inlet channel 24 and a horizontal direction is 170 degrees, and an angle between the oil outlet channel 25 and the horizontal direction is 80 degrees.

[0037] In the embodiment of the present application, front ends of the oil inlets 21 are provided with first end faces 211, and rear ends of the oil inlets 21 are provided with second end faces 212. The first end faces 211 are obliquely and forwardly arranged, and the second end faces 212 are obliquely and backwardly arranged. The first end faces 211 are oblique faces, and the second end faces 212 are cambered faces. Relative to a centerline of the oil guide plate, a highest point of the first end face 211 is 1 mm higher than that of the second end face 212. The oil inlets 21 are provided with two different-height end faces, which solves a problem that oil of a common electric chain saw assembly during rotation may be shaken off in a direction perpendicular to an operating direction of the saw chain, and the end faces are designed as the cambered faces, which can avoid tiny sawdust from being stuck.

[0038] In the embodiment of the present application, an upper end of a rear portion and a low end of the rear portion of the oil guide plate 2 are provided with oil return openings 26, and the oil return openings 26 are communicated with the oil guide channel 23 through an oil return channel 27. The rear end of the oil guide plate 2 is provided with oil filling openings 28, and the oil filling openings 28 are communicated with the oil guide channel 23. By arranging the oil return openings 26, air with very great kinetic energy may be driven to enter the oil return openings 26 by the saw chain rotating at a high speed, so that the lubricating oil flows out from the oil outlets 22 better. The inner walls of the outer guide plates 1 are respectively provided with oil blocking grooves 14 corresponding to the oil return openings 26 and the oil outlets 22, and an oblique direction of the oil blocking grooves 4 corresponding to the oil outlets 22 is the same as a direction of the oil outlet channel 25, and an oblique direction of the oil blocking grooves 4 corresponding to the oil return openings 26 is the same as a direction of the oil inlet channel 24.

[0039] A principle of the present invention is that: when the electric saw is operated, the saw chain, the outer guide plates and the oil guide plate form a relatively sealed space, the air driven by the saw chain rotating at a high speed has very great kinetic energy, and the oil guide plate 2 is provided with different-height first end faces 211 and second end faces 212, so that the huge kinetic energy of the air becomes potential energy, the lubricating oil is pressed into the oil inlets 21 under pressure of the potential energy, and flows into the oil guide channel 23 along the oil inlet channel 24, and the oil may enter the oil outlets 22 along the oil outlet channel 25 under a gravity action, thus lubricating the saw chain, avoiding splashing of the lubricating oil and realizing recycling of the lubricating oil at the same time, and operating the chain more powerfully and smoothly.

Embodiment 2

[0040] As shown in FIG. 5, the embodiment relates to an electric saw guide plate capable of recycling lubricating oil, which comprises two outer guide plates 1 and an oil guide plate 2 mounted between the two outer guide plates 1. A size of the oil guide plate 2 is smaller than sizes of the outer guide plates 1, and outer edges of inner walls of the outer guide plates 1 and a periphery of the oil guide plate 2 form a guide plate groove 3 for containing a saw chain Rear ends of the outer guide plates 1 are provided with mounting grooves 11 and pin holes 12 for fixing the outer guide plates 1 on an engine portion of the chain saw. Front ends of the outer guide plates 1 are provided with positioning holes 13 for fixing the outer guide plates 1 with guide wheels. In the present application, the outer guide plates 1 and the oil guide plate 2 may also be fixed by a common method in the prior art, such as spot welding or laser welding. Four oil inlets 21 are formed in an upper end of the oil guide plate 2 and two oil outlets 22 are formed in a lower end of the oil guide plate. The oil inlets 21 and the oil outlets 22 are communicated through an oil guide channel 23, and the oil inlets and the oil outlets are communicated with the guide plate groove 3 at the same time.

[0041] In the embodiment of the present application, the inner walls of the outer guide plates 1 are provided with oil blocking grooves 14 corresponding to the oil inlets 21, lower ends of the oil blocking grooves 14 are close to the oil inlets 21, and the oil blocking grooves 14 are obliquely and downwardly arranged along front ends of the outer guide plates 1. The oil blocking grooves 14 are used for blocking the lubricating oil carried by the saw chain and shaken off under an inertia effect.

[0042] In the embodiment of the present application, the oil inlets 21 are connected with an oil inlet channel 24, the oil outlets 22 are connected with an oil outlet channel 25, and the oil inlet channel 24 and the oil outlet channel 25 are communicated through the oil guide channel 23. The oil inlet channel 24 is obliquely and downwardly arranged along the front end of the oil guide plate 2, and the oil outlet channel 25 is obliquely and downwardly arranged along the rear end of the oil guide plate 2. An angle between the oil inlet channel 24 and a horizontal direction is 160 degrees, and an angle between the oil outlet channel 25 and the horizontal direction is 60 degrees. An oil storage tank 29 is also connected between the oil inlet channel 24 and the oil outlet channel 25. Oil droplets of the lubricating oil enter the oil inlet channel 24 through the oil inlets 21, and then enter the oil guide channel to be collected in the oil storage tank 29. The lubricating oil in the oil storage tank 29 enters the oil outlets 22 through the oil outlet channel 25 under an air pressure and a self-gravity, thus lubricating the saw chain. The guide plates 1 may be provided with corresponding windows, through which the lubricating oil in the oil storage tank 29 may be observed.

Embodiment 3

[0043] As shown in FIG. 6, the embodiment relates to an electric saw guide plate capable of recycling lubricating oil, which comprises two outer guide plates 1 and an oil guide plate 2 mounted between the two outer guide plates 1. A size of the oil guide plate 2 is smaller than sizes of the outer guide plates 1, and outer edges of inner walls of the outer guide plates 1 and a periphery of the oil guide plate 2 form a guide plate groove 3 for containing a saw chain Rear ends of the outer guide plates 1 are provided with mounting grooves 11 and pin holes 12 for fixing the outer guide plates 1 on an engine portion of the chain saw. Front ends of the outer guide plates 1 are provided with positioning holes 13 for fixing the outer guide plates 1 with guide wheels. In the present application, the outer guide plates 1 and the oil guide plate 2 may also be fixed by a common method in the prior art, such as spot welding or laser welding. Two oil inlets 21 are formed in an upper end of the oil guide plate 2 and two oil outlets 22 are formed in a lower end of the oil guide plate. The oil inlets and the oil outlets are communicated with the guide plate groove 3 at the same time.

[0044] In the embodiment of the present application, a rear end of the oil guide plate 2 is provided with two oil filling openings 28 with symmetrical upper and lower ends, and the oil filling openings 28 are communicated with one oil storage tank 29 at the front end of the oil guide plate 2 through oil filling channels 20. The two oil inlets 21 are communicated with the oil storage tank 29 through the oil inlet channel 24 and the oil guide channel 23, and the two oil outlets 22 are communicated with the oil storage tank 29 through the oil guide channel 23 and the oil outlet channel 25.

[0045] In the embodiment of the present application, two oil filling channels 20 are provided, which correspond to the two oil filling openings 28 one by one. The two oil filling channels 20 are respectively arranged on front and rear sides of the oil guide plate 2. The two oil filling channels 20 have the same size and structure, and a depth of the oil filling channels 20 ranges from 0.5 mm to 1 mm. The lubricating oil enters the oil storage tank 29 through the oil filling openings 28 first and then lubricates the saw chain through the oil outlets 22, and the lubricating oil is recycled from the oil inlets 23 under the drive of the saw chain, thus realizing the recycling of the lubricating oil.
