Technical Field

[0001] The utility model relates to a gluing technology and use equipment, in particular to a vacuum supply and filter air intake integrated device. Background Art

[0002] In the field of gluing technology, vacuum gluing is required in some occasions to ensure the gluing effect. However, in the current vacuum gluing method, the gluing box independently has a corresponding vacuum pump connection port and an air pressure recovery air inlet port after operation. The setting of multiple openings requires multiple airtightness assurance settings. The cost of vacuum gluing is high, and the setting of multiple openings increases the risk of insufficient airtightness.

[0003] Therefore, it is necessary to provide an integrated vacuum supply and filtered air intake device to solve the above problems. Utility Model Content
