Description

The plastic emitting switching device of PUR container

Technical field

The utility model relates to a kind of plastic emitting switching device, espespecially a kind of plastic emitting switching device of PUR container.

Background technology

Thermosol gelgun has become instrument basic in many families or workplace now, and thermosol gelgun indispensable utility especially in the utilization of many repairings; No matter be that thermosol gelgun all occupies an important position in touch-up paint, repairing or modification.

As shown in Figure 8, the thermosol gelgun of prior art is by a rifle body (not shown), one PUR container 80 and a switching device 90 formed, PUR container 80 is located within rifle body, the inside of PUR container 80 is shaped an extrusion chamber 81, the shaping gum outlet 82 in extrusion chamber 81 front end, extrusion chamber 81 rear end is provided with a mobilizable closure plate 83, switching device 90 connects with the gum outlet 82 of PUR container 80 and includes a switching element 91, switching element 91 is the body of a hollow and dual-end, and it has narrow caliber portion 911 and a wide caliber portion 912, narrow caliber portion 911 is not connected with wide caliber, and narrow caliber portion 911 is connected with the gum outlet 82 of PUR container 80, wide caliber portion 912 connects with a plastic emitting valve 92, the outer end of plastic emitting valve 92 is equiped with a glue-spreading head 93, glue-spreading head 93 is the body of a hollow and dual-end, switching element 91, plastic emitting valve 92 is axially communicated with shaping one pipeline with glue-spreading head 93, pipeline is connected with extrusion chamber by gum outlet 82, during use, PUR container 80 is installed in rifle body, makes switching device 90 expose to rifle external, then, by the calandria (not shown) on rifle body, PUR container 80 is heated, make the PUR in extrusion chamber 81 softening and increase mobility, when thermosol gelgun applies pressure to closure plate, PUR in extrusion chamber 81 can be pushed, PUR flowed out by glue-spreading head 93 via the narrow caliber portion 911 of gum outlet 82, switching element 91, wide caliber portion 912 and plastic emitting valve 92, repairs for user, modify or the use of other purposes.

But, when not using when being finished using by this thermosol gelgun, the PUR in PUR container 80 can decline and solidify by Yin Wendu, and the PUR residued in the switching element 91 of switching device 90 also can solidify, and then block switching element 91, have influence on follow-up use.

Therefore, when for reusing, the switching element 91 of switching device 90 can first be separated with the gum outlet 82 of PUR container 80 by some users, more just continues to use after being removed by the residual heat melten gel of switching element 91, but requires great effort again when removing the working expenditure of residual heat melten gel.If do not remove clean, then the residual heat melten gel solidified be stranded in switching element 91 still can hinder the outflow of subsequent thermal melten gel.Used if directly switching element 91 abandons and reinstalls another new switching device 90, then because of the cost intensive of this switching element 91, cause the increase of use cost.

Moreover, the calandria that some users understand Schilling thermosol gelgun heats switching element 91, make obstruction in the residual hotmelt melts solidified of switching element 91 inside, allow the PUR of defective material can flow out from switching element 91 thus and be eliminated clean, but it is external and very far away with the calandria phase tool of thermosol gelgun that switching element 91 is exposed to the rifle of thermosol gelgun, then need the suitable time just can make the residual hotmelt melts of obstruction in switching element 91.And the inner space in the wide caliber portion 912 of switching element 91 is comparatively large, the fusing being positioned at the heat of solidification melten gel at its axle center place is more time-consuming, then quite inconvenience.In order to accelerate to remove, the user separately had in PUR partial melting and mobility is poor time, can first the PUR stagnating in switching element 91, mobility is poor be extruded and abandon, re-use the PUR of follow-up outflow more flowability, but the anti-waste causing PUR.
