As shown in fig. 2, the sprayer 10 further includes a battery 9, the blower assembly 3 and the liquid feeding assembly 4 are electrically connected to the battery 9, respectively, and the battery 9 is used for supplying power to the blower assembly 3 and the liquid feeding assembly 4.

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.

Claims

1. A sprayer is characterized by comprising a shell assembly, a spray head assembly and a fan assembly; the shell assembly is connected with the spray head assembly, the shell assembly is used for storing liquid, the fan assembly is used for generating air flow, and the spray head assembly is used for atomizing and spraying out the liquid output by the shell assembly and is used for blowing out the air flow generated by the fan assembly.

2. The sprayer according to claim 1, wherein the spray head assembly comprises a connecting member, a first fan blade and a spray nozzle, the first fan blade is connected with the spray nozzle, one end of the first fan blade, which is far away from the spray nozzle, is rotatably arranged on the connecting member, and the connecting member is connected with the housing assembly; the first fan blade is blown by airflow generated by the fan assembly to rotate, and the first fan blade drives the nozzle to rotate, so that liquid output by the shell assembly enters the nozzle to be atomized and sprayed out.

3. The sprayer according to claim 2, wherein the fan assembly generates an air flow that moves the liquid from the nozzle outwardly.

4. The nebulizer of claim 1, wherein the housing assembly comprises a first housing and a second housing coupled to the first housing, the second housing for storing a liquid, the spray head assembly coupled to the first housing, the blower assembly disposed within the first housing.

5. The sprayer according to claim 4, wherein the fan assembly comprises a motor and a second fan blade connected to the motor, the motor driving the second fan blade to rotate so that the second fan blade generates an air flow.

6.
