Abstract
The utility model discloses a circuit for supplying power to a fan motor of an air pressure gun, which comprises a power supply, heater strips R1, R2, R2' and R3 and a one-position three-stage switch which are all connected in series to form a loop, wherein the switch is provided with three gears which are a gear I, a gear II and a gear III respectively; R2' is connected in series between the heater strips R2 and R3; the gear II of the switch is connected between the heater strips R2 and R2'; a rectifier bridge has two input ends of which one is connected between the heater strips R1 and R2 while the other is connected between R2' and R3; and a motor M is connected with the output end of the rectifier bridge. In such a way, the hot air pressure gun can adjust the rotating speed of the motor M and the input of the air pressure gun to further adjust the temperature of the air pressure gun under a set power condition.
Description
Technical field
The utility model relates to a kind of heat gun fan electromotor power supply circuits.
Background technology
Existing heat gun fan electromotor power supply circuits comprise power supply, three step switch, heating wire R1, R2, R3, rectifier bridge and motor M, and wherein power supply, heating wire R1, R2, R3 and a three step switch series connection constitute a loop; Described switch is provided with third gear, is respectively I shelves, II shelves, III shelves: the I gear switch is connected on the heating wire R3, and the II gear switch is connected between heating wire R2, the R3, and the III gear switch is a neutral gear, beats on the I shelves when switch, and heating wire R1, R2, R3 are in this loop; Beat on the II shelves when switch, have only heating wire R1, R2 in the loop, heating wire R3 disconnects; When switch is beaten on the III shelves, whole loop disconnects.Two inputs of rectifier bridge are connected to heating wire R2 two ends, and its output is in parallel with motor M.Existing heat gun is provided with three work gears, and wherein the III shelves are neutral gear, and I shelves, II shelves consume different power, and the hot blast of two kinds of different temperature is provided.Because rotating speed and its operating voltage, electric current and the moment of torsion of motor M all are non-linear relations, and the flow of the heat of the temperature of air and absorption and air also is a non-linear relation, so it is difficult that circuit under the condition that satisfies the requirement of high temperature shelves, will satisfy the power and the temperature requirement of low temperature shelves again.
Summary of the invention
The purpose of this utility model is the existing heat gun fan electromotor power supply circuits of improvement, makes it can regulate the rotating speed of two different gear motor M and the air quantity of heat gun, thereby regulates the temperature of heat gun under the setting power condition.
For achieving the above object, the utility model provides a kind of heat gun fan electromotor power supply circuits: comprise power supply, three step switch, heating wire R1, R2, R2 ', R3, rectifier bridge and motor M; Power supply wherein, heating wire R1, R2, R2 ', R3 and a three step switch series connection constitute a loop, described switch is provided with third gear, be respectively the I shelves, the II shelves, the III shelves: the I gear switch is connected on the heating wire R3, the II gear switch is connected heating wire R2, between the R3, the III gear switch is a neutral gear, a heating wire R2 ' also connects in the described loop, it is between heating wire R2 and heating wire R3, described II gear switch is connected heating wire R2, between the R2 ', and two inputs of rectifier bridge, one end is connected heating wire R1, between the R2, the other end is connected heating wire R2 ', between the R3.
Heat gun just can be regulated the air quantity of motor M rotating speed and heat gun like this, thereby regulates the temperature under the setting power condition.
