However, there are some defects in the existing electric glue guns. After the user releases the trigger to stop the glue work: the rubber for containing the glue may be stuck on the top of the end of the retracting rod in the glue cartridge due to being squeezed and folded. It takes force to pull out the rubber and replace it; and, after stopping the glue, the push rod may extend beyond the limit position, which is inconvenient to unlock the push rod; in addition, the glue may flow out or seep out of the nozzle of the glue gun after stopping the glue , resulting in nozzle fouling, adding additional labor costs and time for cleaning the colloid

Embodiment Construction
[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.
[0024] refer to Figure 1 to Figure 4 The shown electric glue gun 100 mainly includes: a prime mover, a casing 12 , and a push-out mechanism 14 .
[0025] A first accommodating cavity 121 is formed inside the casing 12 , the prime mover is arranged in the first accommodating cavity 121 of the casing 12 , and a handle 122 for the operator to hold is also formed in the casing 12 . In this embodiment, the prime mover is the motor 11, and the motor includes a motor shaft 111 for driving the output shaft 145 to swing around the centra...

The invention discloses an electric glue gun. The electric glue gun comprises a motor; the battery pack provides a power supply for the motor; the push-out mechanism is connected to the motor and is driven by the motor to extrude out the glue in the glue barrel; the push-out mechanism comprises a push rod; the controller is at least connected with the motor and used for controlling the rotating state of the motor; the power-on switch is connected with the controller so as to control the power-on state of the controller; the power-off switch is connected with the controller so as to control the power-off time of the controller; and the controller is configured to control the power-off switch to maintain a closed state within a preset time period when the power-on switch is switched off, so that the controller can control the motor to drive the push rod to return. By adopting the electric glue gun provided by the invention, the rubber sheet can be conveniently disassembled, the push rod can be conveniently unlocked, and meanwhile, glue can be prevented from continuously seeping out of the nozzle to generate nozzle dirt after gluing is finished.
Description
technical field [0001] The invention relates to the technical field of electric tools, in particular to an electric glue gun. Background technique [0002] Electric glue gun is a tool that can automatically glue or squeeze glue, which is widely used in architectural decoration, electronic appliances, auto parts and other industries. Compared with the manual glue gun, the electric glue gun in the prior art has a high degree of automation and is relatively labor-saving. However, the existing electric glue gun has some defects. After the user releases the trigger to stop the glue application: the glue used to hold the glue may be stuck on the top of the end of the ejector rod in the glue cartridge due to being squeezed and wrinkled. It takes force to pull out and replace the rubber; and, after stopping the glue application, the push rod may extend beyond the limit position, which is inconvenient to unlock the push rod; in addition, the glue may flow out or seep out of the nozz...
