Small spray device

This creation is about a spray device, especially an easy-to-carry small spray device that uses DC pumping and has the function of pressure relief and water recovery.

According to the conventional sprayer 9, as shown in Fig. a of Fig. 10, mainly a pump 91, water is pumped from a water source to a spray pipe 92, and the spray pipe 92 has a plurality of nozzles 93, and water is sprayed from the nozzles 93. The sprayed water is in the form of smoke. Since the action of the spray is intermittent, there is a period of time for the stagnation without spraying. When the spray is not sprayed, the pump 91 stops the pressurized water from the spray pipe 92, so that there is no pressure in the spray pipe 92. The water in the water spout pipe 92 is dripped from the nozzle 93, and is in a state of dripping water, and it is wet under the water spout pipe 92, which is inconvenient.
