Title:
SPRAY GUN LIQUID STORAGE CUP AND SPRAY GUN LIQUID STORAGE DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/213020
Kind Code:
A1
Abstract:
Disclosed are a spray gun liquid storage cup and a spray gun liquid storage device using same. The spray gun liquid storage cup comprises a cup body (1); the cup body (1) is provided with a ventilation mechanism (3) which allows gas to pass in a forward direction to enter the cup body (1) and does not allow a liquid in the cup body (1) to pass in a reverse direction; the ventilation mechanism (3) comprises a sealing member (32); the sealing member (32), by means of changing the shape thereof, opens the ventilation mechanism (3); and the sealing member (32), by means of changing the shape thereof, closes the ventilation mechanism (3). According to the spray gun liquid storage cup, elastic deformation can be generated along with paint gravity or air pressure, and the sealing member (32) is thus automatically closed or opened, the member of staff operating same does not need to manually open or close the ventilation mechanism (3), and the problem whereby the member of staff operating same needs to manually open and close a cup cover (2) is thus solved; and the automatic opening type ventilation mechanism (3) solves the problem whereby paint leaks out of same or the cup body (1) is broken due to the fact that the member of staff operating same forgets to operate the ventilation mechanism (3).
