Technical Field

The invention relates to the technical field of sprayers, in particular to a handheld electric sprayer with a rotatable spray rod.

Background

When using a hand held sprayer, a user typically needs a longer spray bar so that the spray head is as far away from the body as possible and as close as possible to the target object and spray area, avoiding potential injury to the person during operation. However, the long spray bar makes the product oversize, and the packaging, storage and transportation are inconvenient.

Usually, adopt threaded connection mode or other detachable connected modes between spray lance and the atomizer, not only cause the raffinate hourglass of spray lance and atomizer junction easily when installation and dismantlement, the user uses and also feels inconvenient. Therefore, the connecting mode of the long spray rod and the handheld sprayer which is not required to be disassembled and is convenient to store is the technical difficulty to be solved by the invention.

Furthermore, a limiting block is arranged at the inner corner part of the rotating shaft, two positioning blocks are arranged in the rotating shaft seat in parallel, the rotating shaft rotates in the rotating shaft seat within the range of 180 degrees under the limiting action of the limiting block and the positioning blocks, and an annular locking block is arranged on the outer side of the limiting block.

Furthermore, it forms to spout the chamber shell by two protecting cover amalgamations, and two protecting cover bonding line departments are equipped with a press switch, press switch and spout the intracavity stagnant water valve and link to each other and press and drive the stagnant water valve and open, press through the switch hasp locking between press switch and the stagnant water valve and press.

Furthermore, when the press switch is pressed, the motor trigger wire and the battery contact wire are triggered, and a battery motor connecting wire is arranged between the motor and the battery pack.

Furthermore, the water absorption hose assembly comprises a water absorption hose and an external water absorption device, the external water absorption device comprises a bottle cap and a water absorption pipe which are integrated into a whole, and a plug at the tail end of the water absorption hose is inserted into an opening in the bottle cap and is communicated with the water absorption pipe.

Furthermore, the spraying cavity shell is also provided with a battery cover for manually assembling and disassembling the battery pack.

Compared with the prior art, the invention has the following advantages:

the handheld electric sprayer with the rotatable spray rod is reasonable in structural design, accurate in spraying, stable and reliable in positioning and convenient to store. The spray rod can rotate 180 degrees, so that the total length of the spray rod assembly is twice that of the sprayer body in the working state, and meanwhile, the spray rod assembly has shorter and more compact product size in the storage state; and the water outlet hose passes through the rotating shaft and the spray rod component to be connected with the spray nozzle, so that the distortion, the stretching and the abrasion of the water outlet hose are avoided.
