Unless otherwise defined, all technical and scientific terms used in this article have the same meanings as those commonly understood by those skilled in the technical field of the present disclosure. The terms used in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term “or/and” used in this article includes any and all combinations of one or more related listed items.

In traditional art, a tool fitting of an electric tool generally lack some auxiliary functions (such as lighting, positioning, timing, etc.), and in some scenarios, it requires an additional auxiliary tool to facilitate use. For example, in poor ambient lighting or dark corner spaces, it requires auxiliary components that can supplement light to assist using of the electric tool.

However, additional lighting tools are inconvenient for the operators to operate, but if lighting members are installed on the electric tool, additional power supply component is required, or relatively long wires are required to connect the lighting members to the power supply unit of the electric tool.

Based on above problem, the present disclosure provides a tool fitting 200 for a using process having a fluid flowing and an electric tool 300, in which the tool fitting 200 is a part of the electric tool 300. The tool fitting 200 can be detachably connected to, fixedly connected to, or integrated with other structures of the electric tool 300.

The tool fitting 200 includes a housing 10 and an auxiliary assembly 1001. The housing 10 is provided with a fluid port 11. The auxiliary assembly 1001 is installed on the housing 10. The auxiliary assembly 1001 includes a power generation unit 20A and a function component 1002. The function component 1002 is electrically connected to the power generation unit 20A, and the power generation unit 20A is capable of converting kinetic energy into electrical energy under flowing of a fluid and supplying power to the function component 1002.

By a requirement of the tool fitting 200, the auxiliary assembly 1001 can be a lighting assembly 20, a positioning assembly, a timing assembly, a disinfection and sterilization component, and so on.

For example, taking the tool fitting 200 being a dust suction head 100 as an example, referring to FIGS. 1 to 54, the present disclosure provides a dust suction head 100 configured to be used in the electric tool 300 such as a vacuum cleaner. In particular, the vacuum cleaner (not shown) includes a vacuum cleaner body (not shown). The dust suction head 100 is capable of being fixed on or separated from the vacuum cleaner body. The vacuum cleaner body can generate a suction force and transfer the suction force to the dust suction head 100.

The electric tool 300 is not limited by the vacuum cleaner, and the tool fitting 200 is not limited by the dust suction head 100. For example, the electric tool 300 can be an air blower, and the tool fitting 200 can be a structure located on an air outlet of the electric tool 300. Alternatively, an electric tool 300 can be an electric tool 300 having liquid (such as water or oil) flowing during use, as long as flowing of the fluid can drive the power generation unit 20A to generate electricity. In addition, the dust suction head 100 in the drawings is merely illustrated as an example, and the other forms of dust suction heads, such as a dust suction head with bristles, flat mouthed vacuum cleaners, or long mouthed vacuum cleaners can be used.

Referring to FIGS. 1 to 2, the dust suction head 100 includes a housing 10. The housing 10 is provided with a fluid port 11, an end of the housing 10 away from the fluid port 11 is provided with a connection opening 12, and the connection opening 12 is configured to be connected to the dust suction head 100.

For example, taking a lacked auxiliary function is a light source as an example, in the traditional art, the dust suction head of the vacuum cleaner usually does not have a light source, the vacuum cleaner may be used in poor ambient lighting or dark corner spaces, and it requires additional light to facilitate to cleaning. However, if a lighting member is provided on the dust suction head, a power supply component is required or a relatively long wire is required to connect the lighting member to a power supply unit of the vacuum cleaner.

If a power supply component is provided on the dust suction head, the electricity of the power supply component and a situation of timely charging or replacing a battery when the power supply element is no power are required to be considered. If the relatively long wire is disposed on the dust suction head, a design of the housing 10 is required to change to fix the wire, and a detachment of the dust suction head will be affected.

In addition, the lighting member is generally required to be singly provided with a switch, if the lighting member links the switch of the vacuum cleaner, which requires to be controlled by a circuit or a control unit, thereby increasing a production cost of the vacuum cleaner and the dust suction head.

In addition, in the present disclosure, the lighting member 24 is capable of linking with a switch of the vacuum cleaner. When the vacuum cleaner is in operation and the suction is generated, the fluid starts to flow, the power generation unit 20A is capable of generating power, and the lighting member 24 is capable of lighting. When the vacuum cleaner is out of operation and the suction force is not generated, the fluid stops flowing, and the power generation unit 20A stops generating the power, such that the lighting member 24 is closed.

In some embodiments, the power generation unit 20A includes a magnetic component 22 and a movable component 23. The lighting member 24 is electrically connected to the movable component 23, and the movable component 23 is capable of moving and cutting the magnetic induction lines generated by the magnetic component 22 under the suction force of the vacuum cleaner.

In particular, the movable component 23 includes a rotor 231, and the rotor 231 is capable of rotating and cutting the magnetic induction lines generated by the magnetic component 22. The movable component 23 can use other forms of movement such as linear motion, curved motion, or harmonic motion, as long as the movable component 23 can cut the magnetic induction lines and generate the electricity.

Furthermore, in the present disclosure, as long as the movable component 23 can cut the magnetic induction lines to generate current, a rotation direction of the movable component 23 is not limited. For example, the movable component 23 can cut the magnetic induction lines along X direction, Y direction or Z direction.

Moreover, the magnetic component 22 can be installed after the magnetic component 22 has magnetism or can be magnetized after being installed in the tool fitting 200. A magnetized method of the magnetic component 22 is not limited herein.

Furthermore, the rotor 231 can be a fan (not shown) to increase an area of cut magnetic induction lines, and can be other components, which is not limited herein.
