2. Description of the Related Art The above-mentioned liquid spraying device has been developed for the purpose of uniformly dispersing a liquid over a wide range. FIG. 11 shows a specific configuration of a water spraying device that sprays water, for example, as a conventional example of the liquid spraying device. This water spray device has two dry cells 3
0, a fan 32 rotatable by the driving force of a motor 31 driven by a motor, and a container 33 storing water therein. A manual for discharging water in the container 33 is provided above the container 33. An operation type handle lever 34 is attached. Therefore, when spraying water, a switch (not shown) provided in the apparatus main body is turned on to drive the motor 31 to rotate the fan 32.
By operating the handle lever 34 intermittently or continuously in this state, water is intermittently or continuously discharged from a water discharge port 35 provided at the rotation center of the fan 32. At this time, the water discharged from the water discharge port 35 is dispersed by the airflow generated by the fan 32 rotated from behind, and is sprayed uniformly on a target portion, for example, the entire face.

However, since the wind generated by the rotation of the fan 32 moves forward in a straight line from the front of the fan 32, the water that has exited the water outlet 35 located in front of the fan 32 is As a result, the fan 32 was pushed forward in the state where it came out, so that the fan 32 could hardly exhibit the dispersing function and did not have the function of uniformly dispersing the liquid over a wide range.
Therefore, since the liquid is locally concentrated, the fan 32 must be used farther than necessary from the face. When the fan 32 is used more than necessary as described above,
As the amount of water that does not reach the face increases, not only is there an economic disadvantage that more water must be used to spray water over the face, but also the manual The number of gripping operations of the handle lever 34 has increased, and the operation has been troublesome.
