Title:
SPRAYER
Document Type and Number:
WIPO Patent Application WO/2019/140590
Kind Code:
A1
Abstract:
Disclosed is a sprayer. The sprayer comprises a spraying part. A spray needle passes through a first control channel and reaches a spray end through a second water channel. The spray needle is connected to a control block. The second water channel is provided, near the spray end, with a second control channel. When the spray needle is inserted into the second control channel, the spray needle attaches to an inner wall of the second control channel to block water from passing through the second control channel, and simultaneously, the control block blocks an air inlet, so that water in a water tank is isolated from atmospheric pressure. When the spray needle is separated from the second control channel, the control block is away from the air inlet, so that the water in the water tank is in communication with the atmospheric pressure, and the water can reach the spray end through the second control channel. The spray needle ensures that water stably and reliably flows to the spray end and also simultaneously controls both the flow of water and the communication between the water tank and the atmospheric pressure. When the sprayer is not used, the water tank is in communication with a first water channel, and water in the first water channel cannot flow, thus preventing water in the water tank from flowing out so as to improve the water leakproofness of the sprayer.
