[0032] With reference to the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18, Fig. 19, Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24, Fig. 25, Fig. 26, Fig. 27, Fig. 28 to Fig. Figure 29 comprises a multifunctional handheld fan comprising a housing 1. The housing 1 is provided with a grip area 11 for the user to hold. The housing 1 has an air outlet 2 and an air inlet 3. The air outlet 2 serves to discharge the airflow of the handheld fan. The air inlet 3 can be used as a suction opening to transform the handheld fan into a multifunctional handheld fan.

[0033] The structure described above allows the air outlet 2 of the multifunctional handheld fan to be used for purposes such as quickly cleaning / blowing away dust, quickly cooling by means of a draft, or quickly drying. The air inlet 3 can be used as a suction opening, thereby giving the handheld fan of the present application a vacuum cleaner function and thus expanding it into a multifunctional handheld fan.

[0034] Furthermore, the multifunctional handheld fan includes an air outlet assembly 4 for extending the air outlet function and a vacuum cleaner assembly 5 for extending the vacuuming function. The air outlet assembly 4 is detachably attached to the air outlet 2, and the vacuum cleaner assembly 5 is detachably attached to the air inlet 3. This allows the air outlet 2 to achieve a better air outlet effect by using the extended air outlet assembly 4. Likewise, the air inlet 3 can achieve a vacuuming effect by using the extended vacuum cleaner assembly 5.

[0035] With reference to the Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. 7, as a first embodiment of the interaction of the detachable connection of the air outlet assembly 4 and the detachable connection of the vacuum cleaner assembly 5:

[0036] The air outlet assembly 4 is magnetically detachable from the air outlet 2, which allows for easy assembly and easy installation and removal.

[0037] Furthermore, the air outlet assembly 4 is provided with a first magnetic element 41. Accordingly, the air outlet 2 is provided with a second magnetic element 21, which interacts magnetically with the first magnetic element 41.

[0038] Furthermore, the housing 1 includes a continuous air duct 12. The air outlet 2 is located at a first end of the air duct 12, and the air inlet 3 is located at a second end of the air duct 12. A motor 6 is located within the air duct 12. The center of the air outlet 2 corresponds to the center of the motor 6. The second magnetic element 21 is located at the center of the air outlet 2. Accordingly, the air outlet assembly 4 is an air outlet nozzle, and the first magnetic element 41 is located at the center of the air outlet nozzle. Through the structure described above, air is drawn in through the air inlet 3 under the influence of the motor, flows through the air duct, and then exits through the air outlet 2. Since the airflow during motor operation mainly occurs in the vicinity of the motor, the airflow at the center of the motor is generally weaker.By arranging the first and second magnetic elements 21, 41 in accordance with the center of the motor, in addition to the structural assembly, it is also avoided that these elements obstruct the airflow, thereby ensuring the air performance of the hand fan of the present application and making the structural design rational.

[0039] Furthermore, both the first and second magnetic elements contain 21, 41 magnets.

[0040] Furthermore, in the structure described above, the suction effect of the air inlet 3 can generate a strong suction force, allowing the air inlet 3 to be used for vacuuming. The air outlet assembly 4 is an air outlet nozzle, which is generally round, with the diameter of the nozzle side closer to the air outlet 2 being larger and the diameter of the farther side being smaller. This allows the airflow to be focused during discharge and effectively increases the air outlet performance.

The second magnetic element 21 is attached to the second mounting frame 22. In addition, the combination of the second mounting frame and the second connecting struts at the air outlet 2 can form a protective grille to prevent fingers from accidentally entering the air duct and coming into contact with the motor, thus preventing accidents.

[0042] Furthermore, the housing 1 includes a horizontally continuous air duct 12 and a vertically arranged handle area 11, which represents a rational structural design and facilitates the operation of the multifunctional hand fan of the present application.

[0043] The vacuum cleaner assembly 5 has a suction port opening 51. The suction port opening 51 is equipped with a mounting part 52. The vacuum cleaner assembly 5, with its mounting part 52, is attached to the outer wall of the air inlet 3, so that the suction port opening 51 is positioned in accordance with the air inlet 3 and enables suction from the air inlet 3. Furthermore, the mounting connection ensures that the vacuum cleaner assembly 5 is securely attached to the air inlet 3 and does not easily fall off during the suction process.
