In this embodiment, the structural design of the port 111 can be similar to the bottle cap of a general commercially available water bottle, which usually has an internal thread that matches the mouth of the water bottle. In addition, a perforation is provided in the center of the port 111 so that the water-drawing tube 12 passes through the perforation of the port 111 to pass through the housing 11. In addition, a water inlet structure 121 can be provided at the other end of the water-drawing tube 12, which can have a water filtering function to filter out fine impurities and prevent the impurities accumulated in the water after long-term use from blocking the nozzle 14; in addition, the water inlet structure 121 can also have a plumb bob function to keep the other end of the water-drawing tube 12 at the bottom of the water bottle, which can ensure smooth water inlet. In this embodiment, the water-drawing tube 12 is a hose. Of course, in other embodiments, the water-drawing tube 12 can also be a hard tube, which is not limited by the present invention. In addition, the user can also replace the water-drawing tube 12 as required.

The water pumping motor 13 is disposed in the housing 11, one end of the water pumping pipe 12 is connected to the water pumping motor 13, the nozzle 14 is disposed on the housing 11 and has an atomizing nozzle 141, and the water guide pipe 15 is disposed in the housing 11 and connects the water pumping motor 13 with the atomizing nozzle 141 of the nozzle 14. In this embodiment, when the portable sprayer 10 is in operation, the water pumping motor 13 is first actuated to draw water from the bottle from the water inlet structure 121 of the water pumping pipe 12, and the drawn water flows through the water pumping pipe 12, the water pumping motor 13, and the water guide pipe 15 in sequence to reach the atomizing nozzle 141, and then forms water mist through the atomizing nozzle 141 and sprays out. In addition, the direction of the nozzle 14 is adjustable, for example, the nozzle 14 can have a manually rotatable design or an automatically rotatable design, so that the direction of the water mist spraying can be changed by manual adjustment or automatic adjustment, wherein the nozzle 14 can be manually or automatically rotated (or swung) within an angle of about 180 degrees.

Please refer to FIG. 1A and FIG. 1B again, the operation panel 16 is disposed on the housing 11. In the present embodiment, the operation panel 16 includes an operation switch 161 and a plurality of indicator lights 162, wherein the operation panel 16 includes a circuit board, and the circuit elements of the operation switch 161 and the indicator lights 162 are disposed on the circuit board. For example, the user can long press the operation switch 161 to control the start or shut down of the portable sprayer 10, and when the portable sprayer 10 is started, the user can short press the operation switch 161 to control the power of the water pumping motor 13, thereby controlling the rate (or flow rate) of the water mist spraying, for example, a three-stage flow control can be provided, and the power of the water pumping motor 13 (or the rate of the water mist spraying) can be displayed by the indicator light 162, for example, a three-stage flow rate of strong, medium, and weak can be displayed.

It should be noted that the above control design is only an example, and the present invention is not limited thereto. In other embodiments, the operation panel may include a switch, a function key, and a plurality of indicator lights (not shown), and the user may press the switch to control the start or stop of the portable sprayer, and when the portable sprayer is started, the user may control the power of the water pumping motor by pressing the function key, thereby controlling the rate (or flow rate) of the water mist spraying, for example, a three-stage flow control may be provided, and the power of the water pumping motor (or the rate of the water mist spraying) may be displayed by the indicator light, for example, a three-stage flow rate of strong, medium, and weak may be displayed.

In addition, the user can also control the operating frequency of the water pumping motor by short pressing the operating switch or function key, thereby controlling the frequency of the water mist spraying. For example, a four-stage frequency control can be provided, and the frequency of the water mist spraying can be displayed by means of an indicator light, for example, a four-stage frequency of mode 1, mode 2, mode 3, mode 4, etc. can be displayed. For example, mode 1 can spray water mist once at an interval of 30 seconds and continue to spray water mist for 5 seconds each time, mode 2 can spray water mist once at an interval of 30 seconds and continue to spray water mist for 10 seconds each time, mode 3 can spray water mist once at an interval of 30 seconds and continue to spray water mist for 15 seconds each time, and mode 4 can spray water mist continuously without intervals. It should be noted that the above spray operation design is only an example, not a limitation, and the present invention is not limited thereto. The portable sprayer of the present invention can be designed with different multi-stage spray functions according to actual needs.

Another feasible display mode is listed below. In this example, the operation panel may include two buttons (such as a switch button and a function button) and four indicator lights (not shown), wherein, during the period of starting the spray, the lights are all used to display the power status, for example, when the power is full, the four indicator lights are all on, and when the power is exhausted, the four indicator lights are all dark; when the user presses two buttons at the same time, the indicator lights change to display the current spray interval status (spray mode), for example: when the first indicator light is on, it means that the current spray mode is a spray interval of 30 seconds after spraying water mist for 5 seconds (such as the above-mentioned mode 1), when the second indicator light is on, it means that the current spray mode is a spray interval of 30 seconds after spraying water mist for 10 seconds (such as the above-mentioned mode 2), when the third indicator light is on, it means that the current spray mode is a spray interval of 30 seconds after spraying water mist for 15 seconds (such as the above-mentioned mode 3), and when the fourth indicator light is on, it means that the current spray mode is a continuous spray of water mist without interval (such as the above-mentioned mode 4). Then, after the spray interval status is displayed for 5 seconds, the indicator light automatically jumps back to the display status of the power display.

In addition, please refer to FIG. 1A and FIG. 1B again. The portable sprayer 10 may further include a battery 17 for providing power to the water pumping motor 13 and the operating panel 16. In the present embodiment, the battery 17 is a rechargeable battery, and the portable sprayer 10 further includes a charging socket 18. Therefore, the user can connect the charging socket 18 to a charging cable (such as a USB charging cable with a C-type connector) and connect a power source to charge the battery 17. It should be noted that the above battery design is only an example, and the present invention is not limited thereto. In other embodiments, the battery 17 may be a disposable battery. Whenever the battery 17 is exhausted, the user must replace the battery. However, in this case, the charging socket 18 is not required.

Referring to FIG. 1A again, the portable sprayer 10 may further include a hanging component 19, which is disposed on the side wall of the housing 11; wherein the hanging component 19 is a hanging rope, and its length can be adjusted arbitrarily. With the arrangement of the hanging component 19, the user can hang the portable sprayer 10 at any appropriate position, such as a hook of a motorcycle, a handlebar of a bicycle, etc., so that when the user is riding a motorcycle or a bicycle, the water mist provided by the portable sprayer 10 can effectively reduce the body surface temperature and provide appropriate moisture to the skin.

The following will describe the use of the portable sprayer of the present invention in detail with reference to FIGS. 2 to 4. FIG. 2 is a schematic diagram of the portable sprayer 10 shown in FIG. 1A before being combined with the water bottle 30, FIG. 3 is a schematic diagram of the portable sprayer 10 shown in FIG. 1A after being combined with the water bottle 30, and FIG. 4 is a cross-sectional schematic diagram of the portable sprayer 10 and the water bottle 30 shown in FIG. 3.

For example, a user usually only carries the portable sprayer 10 shown in FIG. 1A. Once necessary, for example, when carrying out outdoor activities (such as riding a motorcycle or a bicycle), he can prepare or purchase general commercially available bottled water (such as a water bottle 30), first remove the bottle cap of the water bottle 30, then take out the portable sprayer 10, put the water-drawing tube 12 together with the water-entry structure 121 into the water bottle 30 (as shown in FIG. 2), and then cover the interface 111 of the portable sprayer 10 with the bottle mouth of the water bottle 30 (as shown in FIG. 3 and 4). In this way, the electronic sprayer can be quickly assembled, and then it is hung in an appropriate position with the help of the hanging component 19, and then the operation panel 16 on the upper side of the portable sprayer 10 is operated, so that the atomizing nozzle 141 of the portable sprayer 10 sprays water mist 50, as shown in FIG. 5. Among them, the operation mode of the operation panel 16 of the portable sprayer 10 can refer to the aforementioned embodiment, and it will not be repeated here.

It should be noted that the above embodiments are only examples, and the portable sprayer of the present invention can be modified in accordance with actual needs without exceeding the claims. For example, as shown in Figure 6, the component configuration and connection relationship of the portable sprayer 10' of another embodiment of the present invention are roughly the same as the portable sprayer 10 of the aforementioned embodiment, and the difference is mainly that: the housing 11' of the portable sprayer 10' of this embodiment has a cross-section that is approximately rectangular (square), and its four corners are arc angles, and its height can be arbitrarily configured. In addition, the body of the nozzle 14' of the portable sprayer 10' is a hose design, and the atomizing nozzle 141' is arranged at one end of the body of the nozzle 14'. With this hose design, the user can arbitrarily bend the body of the nozzle 14' so that the atomizing nozzle 141' can face a specific direction or target, so as to effectively and accurately provide the water mist 50 sprayed by the atomizing nozzle 141' to the target object (such as the user's body or face). In addition, the operation panel 16' of the portable sprayer 10' is arranged on the housing 11', wherein the operation panel 16' includes an operation switch and four indicator lights to indicate four modes of different water mist spraying frequencies. Furthermore, the hanging component 19' of the portable sprayer 10' is arranged on the side wall of the housing 11', wherein the height of the hanging component 19' relative to the side wall of the housing 11' can be arbitrarily adjusted, and with the arrangement of the hanging component 19', the user can hang the portable sprayer 10' at any appropriate position.

In summary, the portable sprayer of the present invention includes a housing, a water-drawing pipe body, a water-drawing motor, a nozzle, a water pipe and an operation panel. An interface is provided on the lower side of the housing. One end of the water-drawing pipe body is arranged in the housing and connected to the water-drawing motor, and the other end thereof passes through the housing from the interface. The water-drawing motor and the water pipe are arranged in the housing. The nozzle is arranged on the housing and has an atomizing nozzle. The water pipe connects the water-drawing motor and the atomizing nozzle of the nozzle. Compared with the known sprayer, the portable sprayer of the present invention may not include a water bottle for containing the spraying liquid, so its overall structure is light and easy to store and carry. When in use, it only needs to be used with, for example, commercially available bottled water. In addition, the portable sprayer of the present invention is pressurized by the water-drawing motor, so it can automatically produce water mist to provide a cooling effect.
