Description

Technical Field

[0001] The utility model relates to the technical field of gardening irrigation equipment, in particular to a handheld water spraying device. Background Art

[0002] Landscape construction is a project to build landscape gardens and green spaces. The purpose of landscape construction is to provide people with a good place for rest, cultural entertainment, and getting close to nature, to meet people's desire to return to nature, and it is also an important measure to protect the ecological environment and improve the urban living environment. During the construction of landscape construction, there will be construction projects such as transplanting large trees, planting small trees and shrubs, paving lawns, and planting ground covers. After the small trees and shrubs, lawns and ground covers are planted, due to the complex and changeable environment of the landscape construction site, the handheld water sprayer is small in size, easy to carry, and has strong adaptability. It can be conveniently used, especially in areas where large water spraying equipment cannot be used, such as narrow areas, next to walls, etc. Therefore, the staff will use handheld water sprayers to spray water on these low vegetation.

[0003] The handheld water spraying device currently in use generally includes a movable water storage bucket, a water pump, a handheld pole, a nozzle mounted on the handheld pole, and a control valve. However, since the length of the handheld pole is fixed, when the vegetation to be watered is far away from the paved road, the staff needs to go around it to water it, and the length of the handheld pole cannot be adjusted as needed, which causes certain inconveniences in use. In view of this, we propose a handheld water spraying device. Utility Model Content
