It is much easier to manufacture and is not easily damaged. More importantly, after the structure of the two is simplified, the advantage is that the volume is also smaller and smaller, making it easy for users to carry around.

Next, the portable sprayer of the present invention separates the pressurizing device 20 and the spray device 30 at the difference of the container 10, in other words, the pressurization of the present invention and the action of releasing the water spray can be operated separately. Thereby, the user can push and pull the operation portion 24 by reciprocating Knowing the hydraulic pressure of the liquid, and accurately grasping the water spray force, and accurately controlling the amount of water sprayed each time.

Furthermore, the pressurization of the portable sprayer of the present invention can be operated separately from the action of releasing the water spray. Thereby, the user can accumulate pressure on the liquid at any time before use, and when the creation is to be used, the pressure relief valve 32 can directly spray water on the skin, which is quite convenient, especially in a race that counts every second. , or when driving, etc., which is inconvenient to operate.

Moreover, the pressurization of the portable sprayer of the present invention can be operated separately from the action of releasing the water spray. Thereby, the user can press the pressure relief valve 32 with one hand to achieve the effect of continuously spraying the skin on the skin without interruption, and thereby massage the skin.

In addition, the head 312b of the spray head has a trumpet shape, which can expand the spray range when the water mist is sprayed outward, as shown in the sixth figure.

It is worth mentioning that the head 312b of the spray head of the spray head extends from the neck 312a away from the container 10, and the axis of the head 312b is inclined to the axis of the container 10, and the user only needs to be small. Rotating the container 10 in an amplitude enables the creation of an excellent angle to spray liquid upwards, downwards, obliquely, obliquely, or laterally toward the skin of the body, particularly at the axis of the head 312b and the container 10 The angle of the axis is 45 degrees and the degree of rotation is the smallest. This advantage makes the present invention easier to operate and less prone to spraining the wrist than the axis of the head of the conventional sprayer is perpendicular to the axis of the container.
