Description

sprinkler

The present invention relates to a spraying device.

According to general gardening watering and woodworking spraying varnish, spraying device will be used for spraying. The conventional spraying device includes a container and an air pump, and the air pump pumps air into the container to increase the pressure in the container. , the liquid in the container can be sprayed to the outside through a water outlet pipe and a nozzle.

However, when the pumping device pumps air into the container, the air will flow into the liquid, and the density of the air is lighter than that of the liquid, and finally the air just floats out of the water surface of the liquid, which will cause the air to dissolve excessively in the liquid, resulting in If the liquid undergoes chemical changes or the inflating effect is reduced, the user needs to expend more effort to inflate, which has disadvantages that need to be improved urgently.

Therefore, it is necessary to provide a novel and progressive spraying device to solve the above-mentioned problems.

The main purpose of the present invention is to provide a spraying device, which can prevent the gas from flowing into the liquid during the pumping process, thereby avoiding the chemical change of the liquid or the reduction of the pumping effect.

To achieve the above object, the present invention provides a spraying device, which includes a container, an inflatable cylinder, an outer cylinder, a nozzle, a water outlet pipe and a control assembly. The container encloses an accommodating space. The air cylinder is arranged on the container, protrudes into the accommodating space and can selectively inflate the accommodating space. The outer cylinder is sheathed on the inflatable cylinder, a channel is formed between the inflatable cylinder and the outer cylinder, and the upper end of the channel communicates with the accommodating space along the vertical direction. The nozzle is arranged in the container and one end communicates with the outside. The outlet pipe is arranged in the container, extends into the accommodating space and communicates with the nozzle. The control component is arranged on the container and can selectively control the communication between the water outlet pipe and the nozzle.

The following examples illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention.
