Abstract: A kind of smokeless barbecue grill, comprises a base and the case placed above the base, which is a hollow structure and above it there is a bracket containing a charcoal tray; one or more fans are arranged on the base; the fan of the barbecue grill is provided with one or more air ducts, which is tilted and bended and forms a certain angle with the longitudinal direction of the barbecue grill. This invention, by improving the above structure, effectively solves the problems with present technology such as non-uniform temperature, non-adjustable fire, and the heavy smoke due to insufficient burning of charcoal when the barbecue grill is working.

Abstract: With respect to a defect that a large-size capacitor is required to implement voltage multiplication in the prior art, the present invention provides a power-type voltage-multiplying driving circuit capable of overcoming the defect. An alternating current power supply J1, a unidirectional conducting element D1, and a charge storing element C are connected in series to form a charging circuit for charging the charge storing element C. A parallel circuit formed by the charge storing element C and the unidirectional conducting element D3 is connected in series to the alternating current power supply J1, a load R, and a switch element SCR to form a load driving circuit for performing voltage multiplication driving on the load R.

Abstract: An electromagnetic nail gun with a lever, comprising a handle for holding the nail gun and triggering the operation of the nail gun, an electromagnetic lever driving device for driving nails with variable speeds through the movement of the lever, wherein electromagnetism is used as driving force, a firing pin slideway for allowing the lever to move therein, and a muzzle magazine assembly for loading nails inside. The present invention uses the magnetism as driving force directly and then applies the lever and variable speed drive to launch nails. Therefore, the structure of the present invention is very simple, light, the manufacture cost is decreased drastically, vibration and noise when used are quite little, very convenient to operate, dispense with the air compressor, easy to carry around.

Abstract: A high-speed electromagnetic nailing gun with a lever, which includes a handle (9), an electromagnetism lever driving device, a ram slideway (3), a muzzle magazine groupware (8). The electromagnetic force is used as the power of the electromagnetic nailing gun, the electromagnetic nailing gun accomplishes nailing by shift-speed driving the ram with the lever (15). It is not necessary for the electromagnetic nailing gun to equip air-pressing accessories, which is convenient to carry, the electromagnetic nailing gun causes little shock and noise when using.
