Abstract
The utility model discloses a kind of socket of bleeding for evacuator, comprise bleeding point and air pipe, one end of described bleeding point and described air pipe is connected and air guide UNICOM, the top of described bleeding point arrange can from the direct fluoroscopic observation in top to described bleeding point bottom viewing device.Viewing device of the present utility model has fluoroscopic observation effect, makes, more accurately convenient to operation when vacuumizing for Vacuumizing bag, to vacuumize efficiency higher.The utility model can be used for various evacuator.
Description
Technical field
The utility model relates to vacuum pumping device field, particularly a kind of socket of bleeding for evacuator.
Background technique
At present, existing evacuator is when vacuumizing wish Vacuumizing bag, first seal described for Vacuumizing bag, then the socket of bleeding of described evacuator is faced toward for behind film sheet (namely the vacuumizing position) place on the surface of Vacuumizing bag, then open evacuator and Vacuumizing bag is vacuumized.In this process, if described in the bleed bleeding point of socket do not aim at for the film sheet on the surface of Vacuumizing bag, will cause and cannot vacuumize and will reorientate socket of bleeding, unhandy problem; Or cause the time vacuumized to spin out, and then make to vacuumize the drawbacks such as efficiency reduction.
Model utility content
The purpose of this utility model aims to provide a kind of convenient operation, vacuumizes the high socket of bleeding for evacuator of efficiency, to overcome deficiency of the prior art.
By a kind of socket of bleeding for evacuator that this object designs, comprise bleeding point and air pipe, one end of described bleeding point and described air pipe is connected and air guide UNICOM, the top of described bleeding point be provided with can from the direct fluoroscopic observation in top to described bleeding point bottom viewing device.
Further, described viewing device is convex lens.
Further, socket of bleeding for evacuator also comprises enclosing cover, in described enclosing cover, support is set, the outer side seal of described viewing device is fixing on the bracket, thus can make to reach between described viewing device and the perisporium of bleeding point and seal air tight and the position structure making described viewing device is more firm, and then further increase vacuumizing efficiency for Vacuumizing bag.
The utility model adopts and arranges the viewing device that can be observed bottom described bleeding point at the top of the bleeding point of socket of bleeding, when exhaust will be carried out to wish Vacuumizing bag, can the socket of bleeding of the described viewing device of band be placed on for above the film sheet (namely vacuumizing position) on the surface of Vacuumizing bag, because described viewing device has amplifying observation effect, therefore can by bleeding point accurate contraposition on above-mentioned film sheet, and the situation of the aperture expansion on above-mentioned film sheet can also be observed in vacuum, operator can understand vacuum pump with or without the air be extracted in bag in time with this, thus the bleeding point solving in prior art socket of bleeding is to being blind operation during described film sheet, whether aligning cannot judge in time, operation inconvenience, the drawback that efficiency reduces, make more accurately convenient to operation when vacuumizing for Vacuumizing bag, vacuumize efficiency higher.
Because the utility model has above-mentioned advantage, the utility model can be used for various evacuator.
Accompanying drawing explanation
Fig. 1 is the perspective view of the described socket of bleeding for evacuator of the utility model embodiment one;
Fig. 2 is the sectional structure schematic diagram of the described socket of bleeding for evacuator of the utility model embodiment one;
Fig. 3 is in the utility model embodiment one, the described structural representation for Vacuumizing bag;
Fig. 4 is in the utility model embodiment one, using state schematic diagram when using the described socket of bleeding for evacuator to vacuumize to described wish Vacuumizing bag.
Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
Embodiment one
As shown in Figure 1, Figure 2 and Figure 4, a kind of socket A that bleeds for evacuator, comprises bleeding point 1, air pipe 2 and enclosing cover 3.Bleeding point 1 is connected and air guide UNICOM with one end of air pipe 2, the connection mouth of another termination vacuum pump of air pipe 2.Observable is set at the top of bleeding point 1 and the viewing device 4 of the bottom of bleeding point 1 can be amplified.Wherein, viewing device 4 is convex lens.Support 5 is set in enclosing cover 3, the outside of viewing device 4 establishes rubber seal 6 to make viewing device 4 sealing be fixed on support 5, thus can make to reach between the perisporium of viewing device 4 and bleeding point 1 and seal air tight and the position structure making described viewing device 4 is more firm, and then further increase vacuumizing efficiency for Vacuumizing bag 7.As shown in Figure 2, a transparent sheet 8 can also be installed additional in the position on enclosing cover 3 and above corresponding viewing device 4, as plastic sheet or glass sheet etc., the protective action to viewing device 4 can be played.
As shown in Figure 3, comprise film sheet 71 on bag 72 and bag 72 surface for Vacuumizing bag 7, film sheet 71 be just used to described vacuumize for Vacuumizing bag 7 vacuumize position.
When needs vacuumize to wish Vacuumizing bag 7, first the sack for Vacuumizing bag 7 is sealed, then the socket A that bleeds of the described viewing device 4 of band is placed on and namely vacuumizes position for the film sheet 71(on the surface of Vacuumizing bag 7) above, then the vacuum pump be communicated with air pipe 2 is opened, because described viewing device 4 has amplifying observation effect, so can by bleeding point 1 accurate contraposition on above-mentioned film sheet 71, the Switch Controller then opening evacuator vacuumizes for Vacuumizing bag 7.Simultaneously, because viewing device 4 has amplifying observation effect, the situation that the aperture on above-mentioned film sheet 71 expands can also be observed in vacuum, whether the air that operator can understand in wish Vacuumizing bag 7 in time with this is pumped, thus the bleeding point 1 solving in prior art socket of bleeding is to being blind operation during described film sheet 71, whether aiming at the drawback that cannot judge, operate inconvenience and vacuumize efficiency in time and reduce, make, more accurately convenient to operation when vacuumizing for Vacuumizing bag 7, to vacuumize efficiency higher.
Above embodiment is only a preference.
Claims (3)
1. the socket of bleeding for evacuator, comprise bleeding point and air pipe, one end of described bleeding point and described air pipe is connected and air guide UNICOM, it is characterized in that, the top of described bleeding point be provided with can from the direct fluoroscopic observation in top to described bleeding point bottom viewing device.
2. the socket of bleeding for evacuator according to claim 1, is characterized in that, described viewing device is convex lens.
