In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details.
As shown in fig. 1-2, an anti-toppling device for an anti-explosion electric heating warm air blower during operation comprises a warm air blower body 1 and an anti-explosion travel switch 2 arranged on the warm air blower body 1;
the normally open point of the explosion-proof travel switch 2 is connected in series with a separation disconnection coil of a master control switch of the fan heater body 1, the explosion-proof travel switch 2 is arranged at the front, rear, left and right side ends of the fan heater body 1, when the fan heater body 1 is toppled, the explosion-proof travel switch 2 is pressed, the normally open point of the explosion-proof travel switch 2 is closed, and therefore the disconnection coil of the master control switch of the fan heater body 1 is electrified to trip and power off, and the fan heater body 1 stops running;
the anti-toppling module is used for preventing the warm air blower body 1 from toppling;
the anti-toppling module comprises a supporting leg 3 arranged at the bottom of the fan heater body 1, a travelling wheel 4 arranged at the bottom of the supporting leg 3, an electric telescopic rod 5 arranged at the corner of the bottom of the fan heater body 1, a backing plate 6 arranged at the lower end of an output shaft of the electric telescopic rod 5, a pressure sensor 7 arranged at the bottom of the backing plate 6, an installation box 8 arranged at the top of the fan heater body 1, a microcontroller 9 arranged in the installation box 8, an adjusting switch 10 arranged on the installation box 8 and electrically connected with the microcontroller 9 and used for controlling the electric telescopic rod 5, a control switch 11 connected into a circuit where a general control switch of the fan heater body 1 is located, and a starting switch 12 arranged on the installation box 8 and electrically connected with the microcontroller 9, wherein the starting switch 12 is used for starting and closing the anti-toppling module, and the electric telescopic rod 5, the pressure sensor 7, the travelling wheel 4, The adjusting switch 10, the control switch 11 and the starting switch 12 are respectively connected with the microcontroller 9 through signals.
The electric telescopic rods 5 are eight, and the eight electric telescopic rods 5 are respectively arranged on the left side of the front end, the right end of the front end, the front side of the left end, the rear side of the left end, the front side of the right end, the rear side of the right end, the left side of the rear end and the right side of the rear end of the bottom of the fan heater body 1.
The walking wheel 4 is a universal wheel with a wheel brake.
Adjusting switch 10 is knob switch, adjusting switch 10 rotates to the right, just can make electric telescopic handle 5's output shaft extend certain length downwards in step, adjusting switch 10 rotates to the left, just can make electric telescopic handle 5's output shaft upwards shorten certain length in step.
The control switch 11 is a relay.
The start switch 12 is a push button switch.
Still be provided with battery 13 in the install bin 8, battery 13 respectively with electric telescopic handle 5, pressure sensor 7, regulating switch 10, control switch 11 and starting switch 12 electric connection to for electric telescopic handle 5, pressure sensor 7, regulating switch 10, control switch 11 and starting switch 12 provide standby electric energy.
Specifically, because explosion-proof travel switch's normally open point is in the separation of the total control switch of electric fan heater body and is taken off a mouthful coil, explosion-proof travel switch installs four sides all around at electric fan heater body, consequently when electric fan heater body emptys, just can oppress explosion-proof travel switch, explosion-proof travel switch's normally open point just can be closed, thereby make electric and trip outage of the take off coil of the total control switch of electric fan heater body, make electric fan heater body stall, thereby avoid electric fan heater body to make electric fan heater body impaired or cause the incident because continue the operation after empting.
When the electric fan heater body is placed on the ground for use, the starting switch can be turned on firstly, then the output shaft of the electric telescopic rod is enabled to extend downwards for a certain length synchronously by means of the adjusting switch until the bottom of the pressure sensor is in direct contact with the ground, the bottom of the walking wheel is enabled to be separated from the ground, the pressure value monitored by the pressure sensor can be recorded by the microcontroller at the moment, the control switch can be enabled to be closed, and the electric fan heater body can enter the running state.
Then if the fan heater body has emptyd in the operation process, the pressure sensor can not be in direct contact with the ground, the pressure sensor can not bear the acting force from the ground any more, so that the monitoring result can be changed, and at the moment, the microcontroller can enable the control switch to be disconnected, so that the fan heater body is separated from the operation state.
Namely, the fan heater body can be stopped to run under the condition that the fan heater body is toppled and pressed to the explosion-proof travel switch through the explosion-proof travel switch; through preventing empting the module, then can make the electric fan heater body bring about to empty but make the electric fan heater body stall when not oppressing explosion-proof travel switch to make its state that breaks away from the operation when the electric fan heater body takes place to empty better, and then avoid the electric fan heater to empty the back because still be in the running state and impaired or even cause the incident.
Particularly, the fan heater body does not completely topple over but leans against an object, and when the explosion-proof travel switch is not pressed, the fan heater body cannot stop running through the explosion-proof travel switch, but a pressure value monitored by the pressure sensor at a certain position is changed because the pressure sensor is separated from the ground, so that even if the fan heater body does not completely topple over, the micro controller can stop running through the control switch because the pressure sensor loses direct contact with the ground.
When the anti-toppling module is not needed, the starting switch is only needed to be closed, for example, when the fan heater body needs to be moved, the output shaft of the electric telescopic rod can be enabled to be synchronously upwards shortened by a certain length through the adjusting switch, and the pressure sensor is enabled to be separated from the ground or far away from the ground.
Through the cooperation of supporting leg, walking wheel, can make the user labour saving and time saving ground remove the electric fan heater.
Through the battery, can provide standby electric energy for electric telescopic handle, pressure sensor, regulating switch, control switch and starting switch to when electric telescopic handle, pressure sensor, regulating switch, control switch and starting switch can't obtain the electric energy through external circuit, still can continue to operate.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
