Or single-chip microcontroller, it is mounted in the annular wall for being connected to the bottom of the outer housing 3, the communication module 82 can be wifi
Chip or Bluetooth chip.In this way, the processing module 81 can receive the bag body 1 that the liquid level detection device 4 detects
Then the scale of construction information of latex in the bag body 1 is transmitted to by the scale of construction information of interior latex by the communication module 82
Middle empty station (middle empty station and the communication module 82 wireless communication connect), to facilitate long-range monitoring.Further, the processing
Module is also electrically connected the breather valve 7 and the baroceptor 5, and the processing module is by receiving the baroceptor
5 numerical value judges whether the air pressure in the bag body 1 is in claimed range, and can by controlling the breather valve 7 come in institute
The air pressure in the bag body 1 is adjusted when stating the air pressure in bag body 1 above or below claimed range.
Further, referring to Fig. 3, the board glue cylinder further includes the alarm module being electrically connected with the processing module 81
83.Specifically, the alarm module 83 includes phonation unit and luminescence unit, the phonation unit can be loudspeaker, described
Luminescence unit can be LED lamp, and the phonation unit and the luminescence unit are arranged in the annular wall.In this way, when described
When the scale of construction for the latex in the bag body 1 that liquid level detection device 4 detects is very few, the processing module 81 controls the sounding
Unit issues the other types of voice prompt such as " serge serge " or " ticking ", meanwhile, it also controls the luminescence unit and issues red length
Light or scintillation light, to remind user to carry out glue operation.
Further, the bag body 1 is separably set to the bag body 1 inside the inner housing 2.Specifically, can institute
Multiple hooks are arranged in the outside for stating bag body 1, meanwhile, multiple links are set in the side wall of the inner housing 2 and the inside of roof, are led to
It crosses multiple hooks and multiple links is corresponded and hooked so that the bag body 1 is separable to be mounted on the inner housing
2 inside.In this way, the bag body 1 can be taken out and carry out clearly during being cleaned to the board glue cylinder
It washes, while replacing clean bag body 1 compatible with the inner housing 2, do not need to clean entire board glue cylinder in this way, greatly
The cleaning efficiency of raising.
It should be pointed out that in other embodiments, the air in the bag body 1 can also be substituted with inert gas.Separately
Outside, the shape of the outer housing 3 and the inner housing 2 is also not limited to cylindrical shape, can also using square tubbiness, triangular prism shape,
Pentagonal prism shape etc..
Implement board glue cylinder provided by the utility model, can achieve it is at least following the utility model has the advantages that
1, by using above-mentioned board glue cylinder, when giving the board glue cylinder glue, need to only open it is described into glue valve, at this time
