Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0030] like Figure 1-5 As shown, a shearing and trimming tool according to an embodiment of the first aspect of the present invention includes a shell 100, a wind wheel power generation module 200, an energy storage module 300 and a shearing and trimming head module. The shell 100 is provided with a power generation duct 110 and an air inlet 120 and a first air outlet 130 both of which are connected to the power generation duct 110. The first air outlet 130 is used to be connected to the dust suction pipe of the vacuum cleaner. The wind wheel power generation module 200 is arranged in the shell 100 and the wind wheel power generation module 200 is at least partially located in the power generation duct 110. The wind wheel power generation module 200 can generate electricity under the action of the wind flow in the power generation duct 110. The energy storage module 300 is electrically connected to the wind wheel power generation module 200 to store the electricity generated by the wind wheel power generation module 200. The shearing and trimming head module is arranged in the shell 100, and the energy storage module 300 is electrically connected to the shearing and trimming head module to power the operation of the shearing and trimming head module.

[0031] It should be noted that, in order to facilitate the user to hold the trimmer, the shell 100 can generally be made into a long cylindrical shape. Of course, this is not specifically limited here, and it can also be made into other shapes according to actual conditions.

[0032] Among them, the energy storage module 300 may include a battery and a charge and discharge circuit board. The charge and discharge circuit board may be provided with a conventional charge and discharge circuit and a voltage stabilizing circuit composed of components such as switching tubes and power management chips. The input end of the voltage stabilizing circuit is electrically connected to the wind turbine generator module 200 to stabilize the electric energy output by the wind turbine generator module 200. The output end of the voltage stabilizing circuit is connected to the charging end of the charge and discharge circuit, and the battery end of the charge and discharge circuit is connected to the battery, thereby storing the electric energy in the battery. The power supply end of the charge and discharge circuit is electrically connected to the shearing and pushing head module, and the battery can also power the shearing and pushing head module through the charge and discharge circuit.

[0033] A vacuum cleaner is generally connected to a vacuum pipe made of a hose, and the housing 100 can be sleeved with the vacuum pipe, so that the first air outlet 130 is connected to the vacuum pipe.

[0034] With the shearing and trimming tool of the present invention, the user can connect the shell 100 with the vacuum cleaner, so that the first air outlet 130 is connected to the dust suction duct of the vacuum cleaner, and the operation of the vacuum cleaner provides suction. The external wind flow can enter the power generation duct 110 from the air inlet 120, and enter the vacuum cleaner from the first air outlet 130 after passing through the wind wheel power generation module 200. The wind wheel power generation module 200 generates electricity under the action of the wind flow in the power generation duct 110 and stores the electricity in the energy storage module 300. When the shearing and trimming head module is needed, the energy storage module 300 can provide electricity for the shearing and trimming head module, so that the shearing and trimming head module can operate stably. The present design can convert wind energy into electricity, and then use the electricity to stably drive the shearing and trimming head module, thereby reducing noise and improving the user's operating experience.

[0035] In some embodiments of the present invention, Figure 1 、 2 As shown, the housing 100 is further provided with a hair suction duct 140, a hair suction port 150 and a second air outlet 160 both connected to the hair suction duct 140. The second air outlet 160 is used to be connected to the dust suction pipe of the vacuum cleaner.

[0036] Since hair will fall after being cut with a clipper, similarly, the shell 100 is connected to the dust suction duct, so that the second air outlet 160 is connected to the dust suction duct of the vacuum cleaner. During the operation of the clipper and clipper head module, the vacuum cleaner can also absorb the hair cut by the clipper and clipper head module through the hair suction duct 140 and the hair suction port 150, thereby preventing a large amount of hair from falling and causing environmental pollution.

[0037] In some embodiments of the present invention, Figure 1 、 2As shown, the shearing and trimming head module includes a shearing and trimming head assembly 400 and a drive assembly 500. The drive assembly 500 is arranged in the shell 100. The energy storage module 300 is electrically connected to the drive assembly 500 to power the drive assembly 500. The drive assembly 500 is connected to the shearing and trimming head assembly 400 to drive the shearing and trimming head assembly 400 to move. The shearing and trimming head assembly 400 and the hair suction port 150 are located at the same end of the shell 100 correspondingly.

[0038] The driving assembly 500 drives the shearing and trimming head assembly 400 to operate, and the shearing and trimming head assembly 400 can trim hair, and the hair suction port 150 is correspondingly arranged near the shearing and trimming head assembly 400. Specifically, it can be located at the same end of the long cylindrical shell 100. The user holds the shell 100 to trim hair, and the end of the shell 100 is facing the position of the hair to be trimmed. While the shearing and trimming head assembly 400 cuts the hair, the hair suction port 150 can more easily suck the hair, thereby improving the hair suction effect.

[0039] In some embodiments of the present invention, Figure 2 As shown, the first air outlet 130 and the second air outlet 160 are located at the other end of the housing 100 away from the shearing and trimming head assembly 400, and the first air outlet 130 and the second air outlet 160 can be connected to the dust collection duct of the vacuum cleaner.

[0040] When using the trimmer, the trimmer head assembly 400 is located at the front end of the shell 100, and the rear end opposite to the front of the shell 100 can be connected to the dust suction pipe of the vacuum cleaner. When the user holds the shell 100 to trim the hair, the dust suction pipe is not likely to hinder the user's operation, thereby improving the user experience.

[0041] At the same time, the first air outlet 130 and the second air outlet 160 can be connected to the dust suction duct of the vacuum cleaner together. Specifically, the first air outlet 130 and the second air outlet 160 can be arranged adjacent to each other. When the shell 100 is connected to the dust suction duct, the first air outlet 130 and the second air outlet 160 can be connected to the dust suction duct together. As a result, when the vacuum cleaner provides suction, part of the external wind flow will enter the power generation duct 110 from the air inlet 120, drive the wind wheel power generation module 200 to generate electricity, and enter the vacuum cleaner from the first air outlet 130, and part of the external wind flow will enter the hair suction duct 140 from the hair suction port 150, and hair will also enter the hair suction duct 140, and then enter the vacuum cleaner from the second air outlet 160. When the shearing and trimming head module of this design is running, the hair suction duct 140 can be used to absorb hair while trimming hair, and it can also generate electricity through the wind wheel power generation module 200, thereby improving the operating endurance of the shearing and trimming head module.

[0042] In some embodiments of the present invention, a middle partition 600 is provided in the shell 100 to separate the interior of the shell 100 into a power generation duct 110 and a hair suction duct 140. The middle partition 600 can separate the internal space of the shell 100 and make the power generation duct 110 and the hair suction duct 140 independent of each other, so that the hair in the hair suction duct 140 is not easy to enter the power generation duct 110, and will not affect the operation of the wind wheel power generation module 200.

[0043] In some embodiments of the present invention, Figure 1 As shown, there are multiple air inlets 120 and the multiple air inlets 120 are arranged around the local circumference of the shell 100. The multiple air inlets 120 can reduce wind resistance and at the same time can let air in from the circumference of the shell 100, preventing the user from blocking the air inlets 120 in certain directions during operation and affecting the power generation effect.

[0044] In some embodiments of the present invention, Figure 3 、 4 As shown, the shearing head assembly 400 includes a stationary blade 410 and a movable blade 420. The stationary blade 410 is arranged in the shell 100, and the movable blade 420 is movably arranged in the shell 100. The driving assembly 500 can drive the movable blade 420 so that the movable blade 420 and the stationary blade 410 can realize reciprocating shearing motion.

[0045] The stationary blade component 410 includes a first connecting seat 411 and a plurality of transversely arranged stationary blade portions 412 on the first connecting seat 411, and a gap is set between each pair of the stationary blade portions 412, while the movable blade component 420 includes a second connecting seat 421, and the second connecting seat 421 is provided with a plurality of transversely arranged moving blade portions 422, and a gap is set between each pair of the moving blade portions 422. The stationary blade portions 412 and the moving blade portions 422 are staggered through the gaps, and the adjacent stationary blade portions 412 and the moving blade portions 422 are closely attached to each other so as to move closer and further away from each other to realize shearing movement. When the stationary blade portions 412 and the moving blade portions 422 are close to each other, they can cut the hair therein.

[0046] Specifically, the movable blade 420 can be slidably set on the shell 100, and the adjacent static blade parts 412 and dynamic blade parts 422 can be moved closer to or farther away from each other through sliding translation, or the movable blade 420 can be rotatably set on the shell 100, and the adjacent static blade parts 412 and dynamic blade parts 422 can be moved closer to or farther away from each other through swinging.

[0047] The driving assembly 500 can adopt a driving motor 510, and the driving end of the driving motor 510 is connected to the cam 520. The eccentric portion of the cam 520 can contact the movable blade 420. The driving motor 510 drives the cam 520 to rotate, and the eccentric portion of the cam 520 drives the movable blade 420 to reciprocate relative to the stationary blade 410.

[0048] In some embodiments of the present invention, Figure 3 As shown, the wind wheel power generation module 200 includes at least one first wind wheel 220 and a generator 210 . The driven shaft of the generator 210 is connected to each first wind wheel 220 , and the generator 210 is electrically connected to the energy storage module 300 .

[0049] The first wind wheel 220 is driven by the wind flow, thereby driving the driven shaft of the generator 210 to rotate. The generator 210 generates electricity and then stores the electrical energy in the energy storage module 300. The structure is simple, the wind flow is effectively utilized, and the conversion efficiency of wind energy to electrical energy is improved. Specifically, the diameter of the first wind wheel 220 is roughly equal to the inner diameter of the power generation air duct 110, thereby preventing the leakage of the wind flow and improving the utilization rate of the wind flow.

[0050] In some embodiments of the present invention, Figure 5 As shown, the wind wheel power generation module 200 also includes at least one second wind wheel 230, the second wind wheel 230 is arranged in the shell 100 and the second wind wheel 230 is located in the power generation duct 110, the second wind wheel 230 is arranged adjacent to any one of the first wind wheels 220, the first wind wheel 220 is provided with a plurality of first wind blades 221 arranged circumferentially around the driven axis of the generator 210, the second wind wheel 230 is provided with a plurality of second wind blades 231 arranged circumferentially around the driven axis of the generator 210, and the first wind blades 221 and the second wind blades 231 have different swing directions.

[0051] The second wind wheel 230 can be mounted on the driven shaft of the generator 210 through a rotating bearing sleeve. The second wind wheel 230 is stationary relative to the shell 100. Since there is a ventilation gap between adjacent first wind blades 221, there is also a ventilation gap between adjacent second wind blades 231. When the first wind wheel 220 is driven to rotate by the wind flow, the first wind wheel 220 rotates relative to the second wind wheel 230, and the wind flow can pass through the ventilation gap between the second wind blades 231. Since the first wind blades 221 and the second wind blades 231 have different swing directions, the wind flow guided by the second wind blades 231 will hit the surface of the first wind blades 221, driving the first wind blades 221 to rotate rapidly, thereby improving the conversion rate of wind energy to electrical energy.

[0052] Specifically, the first wind wheels 220 and the second wind wheels 230 are paired one by one, and the first wind wheels 220 and the second wind wheels 230 are arranged alternately.

[0053] In some embodiments of the present invention, Figure 2As shown, a accommodating chamber 170 is further provided in the shell 100, and the accommodating chamber 170 is communicated with the power generation air duct 110. The energy storage module 300 is located in the accommodating chamber 170. The wind flows into the power generation air duct 110 from the air inlet 120 and then flows out from the first air outlet 130. The wind can take away the heat of the components in the accommodating chamber 170. At the same time, since the opened accommodating chamber 170 is not on the path of the wind flow, the components located in the accommodating chamber 170 will not cause too much obstruction to the flow of wind flow, which is beneficial to improving the conversion rate of wind energy to electrical energy.

[0054] Specifically, the air inlet 120 can be set in the middle of the shell 100, the first air outlet 130 can be set at one end of the shell 100, the shearing and trimming head assembly 400 can be set at the other end of the shell 100, and the accommodating cavity 170 can be set from the air inlet 120 to the other end of the shell 100. Of course, components such as the drive assembly 500 can also be located in the accommodating cavity 170.

[0055] In some embodiments of the present invention, the accommodating chamber 170 may be located between the air inlet 120 and the first air outlet 130 , and the accommodating chamber 170 is opened on one side of the power generation air duct 110 .

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
