Abstract
The utility model relates to a blowing and suction machine, which is designed for improving the safety performance of the prior blowing and suction machine. The blowing and suction machine with a safety device comprises a main body with an air inlet, an electric fan, a blowpipe, a suction pipe, a dust collection bag and a switch; a micro-switch is arranged on one side of the air inlet, and a handspike is arranged below the micro-switch; an auxiliary handle with a cam is arranged at the main body below the micro-switch, and the auxiliary handle is fixed at the main body by a pin and can rotate circling the pin; when the auxiliary handle rotates to covering the air inlet, the cam drives the handspike and springs the micro-switch. The utility model has the advantages that adding the safety device to the prior blowing and suction machine can avoid hands or other body parts touching the fan when using the machine and suffering damage, and improve the operation safety.
Description
Technical field
The utility model relates to a kind of pressure-vaccum blower fan, particularly has the pressure-vaccum blower fan of Safeguard.
Background technique
Existing pressure-vaccum blower fan comprises main machine body, electric fan, suction pipe, air feeding tube, collection bag, switch.When the air draught state, wind is entered the collection bag after the air sucking mouth of suction pipe sucks by induced draught fan, by suction pipe leaf, little branch in vain and other easy broken wisp is sucked like this, and smashes the back collection by fan blade and exist in the collection bag.At the blowing state, wind is sucked by the air sucking mouth of fan from suction pipe, enters air feeding tube, and wind is compressed, and the blowing mouth from air feeding tube blows out very strong wind like this, thereby things such as leaf, dust are blown away.But because the electric fan at the intake grill place of pressure-vaccum blower fan is exposed at present, damage other positions of operator's hand and health easily, operate dangerous.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and a kind of pressure-vaccum blower fan with Safeguard is provided, and makes that it seals when the pressure-vaccum air inlet is worked, quits work during opening, reaches the purpose of safety operation.
The utility model solves the problems of the technologies described above the technological scheme that is adopted:
The pressure-vaccum blower fan of band Safeguard, comprise main machine body, electric fan, air feeding tube, collection bag, the switch of bringing the air port into, described intake grill one side is installed sensitive switch, the sensitive switch downside is installed push rod, the assist handle of push rod downside mounting strap cam on main machine body, assist handle is fixed on the main machine body by pin, can rotate around pin, and cam promotes push rod and triggers sensitive switch in the time of on being buckled in intake grill.
Described suction air feeding tube is descending to the using end caliber from fan.
Compared with prior art, advantage of the present utility model is to increase safety protection mechanism on existing pressure-vaccum blower fan, can avoid staff or other body parts when using the pressure-vaccum blower fan, to run into fan, make staff and other positions exempt from damage, improve the Security of operation.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an explosive view of the present utility model.
Embodiment
Embodiment is described in detail the utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the pressure-vaccum blower fan comprises fuselage, and motor 7, fan 31 and 1,3, two sections suction pipes 27,28 of 18, two sections air feeding tubes of power line thereof can place the collection bag 2 on the control of dust frame 5, main switch 24, assist handle 34.Fuselage is fixing by screw 11 by left casing 4 with handles, right casing 10, fan 31 is fixed on the axle of motor 7 by axle sleeve 30 and nut 32, rubber stopper 33, and then be fixed on the fuselage, intake grill 20 1 sides are installed sensitive switch 23, sensitive switch 23 downsides are installed push rod 25, the assist handle 34 of strap cam 22 is fixed on the fuselage by pin 35, back-up ring 26, and assist handle 34 can rotate around pin 35.Also have power line cover 16 and flex holder 17.
Air feeding tube is divided into two sections, and its sectional area progressively reduces from fan place to using end, can play the effect that pressurized air increases air quantity like this.
During work, start main switch 24, assist handle 34 blocks intake grill 20; cam 22 on the assist handle 34 withstands sensitive switch 23 by push rod 25, and the pressure-vaccum blower fan is started working, at this moment; assist handle has blocked has sealed intake grill 20, and protection hand and other body parts enter intake grill 20 and injured.
During the dress suction pipe; earlier assist handle is turned to the opposite side of fuselage around pin; fasten assist handle by the hook on the fuselage 21; when suction pipe is packed intake grill into; its head promotes push rod, and push rod withstands switch again and starts sensitive switch 23, and the pressure-vaccum blower fan is started working; blocked intake grill by suction pipe this moment, and protection hand and other body parts enter intake grill and injured.
Assist handle is after its stationary axle leaves intake grill, and the cam of assist handle leaves push rod, and push rod just leaves sensitive switch, and switch flicks, and machine quits work, so hand and other positions of health can be not injured.
Claims (4)
1, the pressure-vaccum blower fan of band Safeguard, comprise main machine body, electric fan, air feeding tube, collection bag, the switch of bringing the air port into, it is characterized in that: described intake grill one side is installed sensitive switch, the switch downside is installed push rod, the assist handle of push rod downside mounting strap cam on main machine body, assist handle is fixed on the main machine body by pin, can rotate around pin, and cam promotes push rod and triggers sensitive switch in the time of on being buckled in intake grill.
