Detailed description of the invention

Below in conjunction with embodiment, the utility model is further illustrated:

Embodiment one:

In the present embodiment, see Fig. 1 ~ Fig. 7, to the use of PUR pen device, specifically can be divided into and realizing with recessed step:

As as described in Fig. 1 embodiment, zone of heating 1 is connected with power line 4, heat insulation ply of paper 2 is wrapped up outside zone of heating 1, adiabatic silicon rubber loop 6 is wrapped up by heat insulation ply of paper 2, the side of adiabatic silicon rubber loop 6 seals with glue chamber 16 and contacts, the other end is connected with spring 7 by retainer plate, the other end of spring 7 is fixed on the crossbeam 14 of the cap for brush 13, the cap for brush 13 is connected by a rotatable brace 12 with depression bar 11, depression bar 11 other end is connected with upper packed-piston 10, upper packed-piston 10 is connected with lower seal piston 8 by two slide plates 9 as shown in Figure 4, upper packed-piston 10 is under pressure slide downward, lower seal piston can be compressed, play sealing function, when the cap for brush 13 is by compression, knob 17 on rotary pen cap 13, two teeth 20 will embed as shown in Figure 7 in teeth hole as shown in Figure 2, the pipe contact cap for brush 13 one end in PUR pen device, in PUR pen device, pipe upper end has as shown in Figure 3, with the cap liner 18 that screw can be dismantled.

By the cap liner 18 with screw when A. using, arbitrarily disassemble from inner pen tube, by the cap for brush 13, the depression bar 11 connected and upper packed-piston 10, brace 12 takes out together with lower seal piston 8 from a chamber, a bit of hot melt rubber stick between the length 4-6cm of 7mm diameter is intercepted, puts into PUR pen device glue chamber 16;

B. the cap for brush 13 will taken out, the depression bar 11 of connection and upper packed-piston 10, brace 12 and lower seal piston 8 are kept in the center, and screw on cap liner 18.Power line 4 switches on power, and zone of heating 1 starts heating, and glue rod starts to melt, until when glue mouth 19 has PUR to overflow, PUR pen device can use;

C. with pointing to pressing down the cap for brush 13, pressure suffered by the cap for brush 13 is transmitted to depression bar 11, depression bar 11 promotes upper packed-piston 10 and moves downward on slide plate 9, until contact with lower seal piston 8, four pores 15 as shown in Figure 5 on lower seal piston 8 seal up by upper packed-piston 10, continue to apply pressure, then upper-lower seal piston entirety moves down, 5 li, chamber defines closed gas, along with the increase of pressure, with the motion of piston, the increasing pressure of closed gas is large, promote PUR and go out motion to glue mouth 19, glue mouth 19 is aimed at the place needing to use PUR, continue to apply pressure, the use amount of PUR can be determined according to cap for brush rule as shown in Figure 7,

D. finger is unclamped, by the spring 7 meeting resilience compressed, withstand crossbeam 14, drive depression bar 14, depression bar 11 connects upper packed-piston 10, move up, there is gas to enter in a chamber by the pore 15 of lower seal piston 8 simultaneously, when upper packed-piston 10 slides into the maximum range of slide plate 9, drive slide plate 9 and lower seal piston 8 are moved up, until get back to initial position, the continuation that cap liner 18 limits brace 12 is moved;

Repeat the use that aforesaid operations completes PUR pen device.

Embodiment two:

The present embodiment is substantially identical with embodiment one, and special feature is:

In the present embodiment, see Fig. 1 ~ Fig. 6, following four steps specifically can be divided into realize the use of PUR pen device:

A. to outward winding cap liner 18, take out piston, put into hot melt rubber stick: identical with embodiment one;

B. put back to piston, cycle cap liner 18, switches on power: identical with embodiment one;

C. apply pressure, PUR overflows gum outlet 19: identical with embodiment one;

D. pinch the knob 17 on the cap for brush 13 with hand, teeth 20 screwed in as in the shaft of a writing brush in Fig. 2, then PUR is not in spilling, PUR vertically can be hung over optional position.

By way of example the utility model is illustrated above; but the utility model is not limited to above-mentioned specific embodiment; according to the change made under the principle of technical solutions of the utility model, modification, combination, simplification; all should be the substitute mode of equivalence, all belong to the scope that the utility model is claimed.
