Abstract
The utility model discloses a three -way fan, including three -way fan, hot -blast marksman's handle shell, safety guard, heat -generating body, nozzle, temperature sensor, steel drum and the hot -blast rifle joystick control line of taking the wind speed inspection, hot -blast marksman's handle shell left side internally mounted has the three -way fan who takes the wind speed inspection, hot -blast marksman's handle shell right -hand member is connected with the safety guard, the steel drum passes the safety guard and extends to inside hot -blast marksman's handle shell, nozzle install is at the steel drum right -hand member, hot -blast rifle joystick control line sets up inside hot -blast marksman's handle shell, just hot -blast rifle joystick control line is connected with heat -generating body and temperature sensor respectively, the heat -generating body is installed inside the steel drum. This three -way fan, can automated inspection the fan rotational speed, cross when low when fan stall or rotational speed, the singlechip automatic control disconnection heat -generating body power supply and the suggestion of reporting to the police, assurance temperature sensor can reliably detect the heat -generating body temperature, and simple structure, reasonable in design, low energy consumption and easily use widely.
Description
Technical field
This utility model relates to electric heating equipment technical field, is specially a kind of three line blower fans.
Background technology
Two positive negative wires of traditional blower fan only power supply, blower fan whether stall can not be detected, heat gun operation principle is that air is passed through air inlet suction heat gun handle by blower fan, through heater, the heat of heater is taken out of the air outlet being provided with temperature sensor, temperature sensor by time reality temperature data return to the single-chip microcomputer within machine to control heater power pulses width, formed 100-500 degree constant high-temperature gas from air outlet spray, to object heat. Air is not had to deliver to air outlet when blower fan breaks down stall, temperature sensor just can't detect heater temperature rise, heater persistent fever, heat is gathered in air pressure gun handle inner in a large number, until heating wire fusing, too high temperature can make outer steel drum rubescent, and plastic handle melts and catching fire, causes major safety risks.
Utility model content
The purpose of this utility model is in that to provide a kind of three line blower fans, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of three line blower fans, including the three line blower fans checked with wind speed, heat gun handle casing, safety guard, heater, nozzle, temperature sensor, steel drum and heat gun handle control line, internally installed on the left of described heat gun handle casing have the three line blower fans checked with wind speed, described heat gun handle casing right-hand member is connected to safety guard, described steel drum extends to inside heat gun handle casing through safety guard, described nozzle is arranged on steel drum right-hand member, described heat gun handle control line is arranged on inside heat gun handle casing, and described heat gun handle control line is connected with heater and temperature sensor respectively, described heater is arranged on inside steel drum.
Preferably, described temperature sensor is arranged on the right-hand member of heater.
Preferably, described nozzle is provided with air outlet.
Compared with prior art, the beneficial effects of the utility model are: this three lines blower fan, have employed the three line blower fans that can check rotation speed of fan, single-chip microcomputer checks rotation speed of fan in real time, when blower fan stall or rotating speed are too low, Automatic control of single chip microcomputer disconnects heater and powers and alarm, heater stops heating, can automatically detect rotation speed of fan, when blower fan stall or rotating speed are too low, Automatic control of single chip microcomputer disconnects heater and powers and alarm, ensure that temperature sensor can reliably detect heater temperature, solve because of fan trouble, heater continuous heating, the problem burning heat gun handle, the generation of the potential safety hazard effectively avoided, extend service life of fan, improve production efficiency, and simple in construction, reasonable in design, low energy consumption and use easy to spread.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: the 1 three line blower fans checked with wind speed, 2 heat gun handle casings, 3 safety guards, 4 heaters, 5 nozzles, 6 air outlets, 7 temperature sensors, 8 steel drums, 9 heat gun handle control lines.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, this utility model provides a kind of technical scheme: a kind of three line blower fans, including the three line blower fans 1 checked with wind speed, heat gun handle casing 2, safety guard 3, heater 4, nozzle 5, temperature sensor 7, steel drum 8 and heat gun handle control line 9, internally installed on the left of described heat gun handle casing 2 have the three line blower fans 1 checked with wind speed, described heat gun handle casing 2 right-hand member is connected to safety guard 3, it is internal that described steel drum 8 extends to heat gun handle casing 2 through safety guard 3, described nozzle 5 is arranged on steel drum 8 right-hand member, it is internal that described heat gun handle control line 9 is arranged on heat gun handle casing 2, and described heat gun handle control line 9 is connected with heater 4 and temperature sensor 7 respectively, it is internal that described heater 4 is arranged on steel drum 8, described temperature sensor 7 is arranged on the right-hand member of heater 4, described nozzle 5 is provided with air outlet 6.
This utility model is improved by: this three lines blower fan, have employed the three line blower fans 1 checked with wind speed, single-chip microcomputer checks rotation speed of fan in real time, when blower fan stall or rotating speed are too low, Automatic control of single chip microcomputer disconnects heater and powers and alarm, heater 4 stops heating, can automatically detect rotation speed of fan, when blower fan stall or rotating speed are too low, Automatic control of single chip microcomputer disconnects heater 4 power supply alarm, ensure that temperature sensor 7 can reliably detect heater 4 temperature, solve because of fan trouble, heater continuous heating, the problem burning heat gun handle, the generation of the potential safety hazard effectively avoided, and simple in construction, reasonable in design, low energy consumption and use easy to spread.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, being appreciated that when without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, amendment, replacement and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
