Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically a handheld spray fan. Background Technology

[0002] A fan is an electrical appliance that uses an electric motor to drive fan blades to rotate, thereby accelerating air circulation. Fans are mainly used for cooling and air circulation. Currently, fan technology only dissipates heat through airflow. In hot weather, the air has low moisture content, and the body loses moisture quickly, so comfort needs improvement. Utility Model Content

[0003] The purpose of this invention is to improve the user experience by providing a handheld misting fan.

[0004] To address the aforementioned problems, this utility model proposes a handheld fan with a spray function, comprising a handle and a fan tube located on the upper part of the handle. The fan tube is annular, with fan blades installed in the middle. The inside of the fan tube is hollow, forming a water storage cavity. A water outlet is located at the bottom of the fan tube, and a sprayer is provided on the handle. The water inlet of the cavity and the sprayer are connected to the water outlet of the fan tube.

[0005] Furthermore, the spray direction of the sprayer intersects with the air outlet direction of the air duct.

[0006] Furthermore, the angle between the spray direction of the sprayer and the air outlet direction of the blower is 0 to 80 degrees.

[0007] Furthermore, a motor for driving the fan blades is installed in the middle of the air duct.

[0008] Furthermore, the handle includes two half-open housings, with elastic latches and protrusions respectively provided at the joint position of the two housings, and the elastic latches and protrusions interlocking when the housings are fitted together.

[0009] Furthermore, the handle is equipped with a gear switch, which is a stepless switch.

[0010] Furthermore, the top of the air duct is provided with a water injection hole, and a rear cover is provided at the rear of the air duct, on which a plug that matches the water injection hole is installed.

[0011] Furthermore, the handle is also provided with a hole for the sprayer, and a plug is provided for the hole.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] Sprayers can provide moisture, increase air humidity, make people feel comfortable in dry environments, and add a new way of cooling, allowing people to enjoy a cool and moist feeling at the same time. At the same time, the use of a ring-shaped air duct can direct water towards the lower part of the sprayer, achieving a high utilization rate of spray water. Attached Figure Description

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] like Figures 1 to 6 As shown, this utility model provides a handheld fan with a spray function, including a handle 1 and a fan tube 2 located on the upper part of the handle 1. The fan tube 2 is annular, with fan blades 3 installed in the middle. The inside of the fan tube 2 is hollow, forming a water storage cavity. A water outlet 4 is located at the bottom of the fan tube 2. A sprayer 5 is provided on the handle 1, and the water inlet 501 of the cavity and the sprayer 5 is connected to the water outlet 4 of the fan tube 2. In this design, the sprayer 5 can provide moisture, increase the humidity of the air, make people feel comfortable in dry environments, and add a new way of cooling, allowing people to enjoy a cool and moist feeling at the same time. At the same time, the annular fan tube 2 can make water flow towards the lower sprayer 5, achieving high utilization of spray water.

[0022] Secondly, the spray direction of the sprayer 5 intersects with the air outlet direction of the air duct 2. In other words, the spray direction of the sprayer 5 exactly crosses the air outlet direction of the air duct 2. This allows the water mist to spread further with the wind, ensuring that the water mist can directly reach the user's face, providing a more comfortable experience.

[0023] More specifically, an angle of 0 to 80 degrees is sufficient. Because sprayer 5 is a diffuser, a 0-degree angle can ensure that some of the sprayed water mist overlaps with the airflow. Of course, the angle can be adjusted according to the diffusion angle of sprayer 5 to ensure that some water mist overlaps.

[0024] In this embodiment, the fan blades 3 and motor 6 are fixed in the middle of the air duct 2, which ensures their stability and consistency during operation. This also makes the fan look very simple and aesthetically pleasing overall.

[0025] In this embodiment, the handle 1 is composed of two half-open shells. The mating surfaces of the two shells are respectively provided with elastic latches 16 and protrusions 15, which can interlock when the shells are fitted together to form a single, integrated handle. This design makes the assembly of the handle more convenient.

[0026] In this embodiment, the circuit board 7 and battery 8 are fixed in the handle 1. The front end of the handle 1 has a spray switch 9 and a speed control switch 10. The spray switch 9 controls the opening and closing of the sprayer 5, and the speed control switch 10 controls the wind speed. Users can switch freely as needed. This speed control switch can be a stepless switch, also called a stepless speed control switch. It is generally based on the principle of variable resistance. It has a continuously adjustable knob or slider. Internally, it mainly includes a resistor, brushes, and terminals. When the knob is rotated or the slider is moved, the position of the brush on the resistor changes, thereby changing the resistance value connected to the circuit. In the circuit controlling the wind speed, the stepless switch is connected in series with the motor 6. When the resistance of the stepless switch increases, according to Ohm's law, the current in the circuit decreases. Since the motor speed is related to the current flowing through it, a decrease in current leads to a decrease in motor speed, thus reducing the wind speed; conversely, when the resistance decreases, the circuit current increases, the motor speed increases, and the wind speed increases. This continuously adjustable resistor method allows for stepless control of wind speed, enabling users to adjust the wind intensity to any desired level. In contrast, stepped switches only have a few fixed settings, such as "high," "medium," and "low." Stepless switches, on the other hand, can be continuously adjusted within a certain range, more precisely meeting users' requirements for different wind intensities.

[0027] In this embodiment, the handle 1 has a charging port 11 and a power switch 12 on the back. The charging port 11 is used to charge the battery 8, and the power switch 12 controls the opening and closing of the battery 8. When the power is on, it works with the gear switch 10 to control the airflow.

[0028] In this embodiment, the top of the air duct 2 is provided with a water injection hole 201, and the rear of the air duct 2 is provided with a rear cover 13. The rear cover 13 is fused with the air duct 2 by ultrasonic process to ensure airtightness. A silicone plug 14 that matches the water injection hole 201 is installed on the rear cover 13 to prevent water leakage.

[0029] In this embodiment, the handle 1 is also provided with a hole for the sprayer 5. The main function of this hole is to allow the sprayer 5, which is located inside the handle 1, to smoothly spray water mist. Correspondingly, a plug 14 is provided for this hole. The plug 14 is mainly to ensure the cleanliness of the spray nozzle of the sprayer 5 and to prevent dust and dirt from accumulating on the sprayer 5 after a long period of disuse, which would affect the spraying effect. By providing the plug 14, this situation can be effectively avoided, ensuring that the sprayer 5 can always be kept clean, thereby ensuring the user's respiratory health.

[0030] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
