[0066] In a preferred embodiment, the projection of the air inlet of the second fan 51 based on the central axis of the second diffuser 5 at least partially overlaps with the projection of the second air inlet mesh 52 based on the central axis of the second diffuser 5, but is not limited thereto.

[0067] In a preferred embodiment, the diffuser is cylindrical, but this is not a limitation.

[0068] The specific embodiments of this utility model are as follows:

[0069] refer to Figures 1 to 3 As shown, the table fan with diffusers of this utility model includes: a base 1, a support rod 2, a three-way connector 3, a first diffuser 4 and a second diffuser 5 in cylindrical shape. The first diffuser 4 and the second diffuser 5 are symmetrical about the three-way connector 3. The support rod 2 includes a straight end 21 and a bent end 22, with the straight end 21 connected to the base 1. The main connecting pipe 33 of the three-way connector 3 is rotatably connected to the bent end 22 of the support rod 2. Each of the two diffusers is rotatably connected to a first branch pipe 31 and a second branch pipe 32 of the three-way connector 3. The diffuser is hollow inside, forming an air passage. The first end of the diffuser connected to the three-way connector 3 has an air inlet and a fan. The shell opposite the second end of the three-way connector 3 has at least one air outlet. The air generated by the fan flows through the air passage to the second end and is emitted outward from the air outlet. The desktop fan of this utility model mainly consists of the support rod 2 and the three-way seat 3, the first diffuser 4, and the second diffuser 5, which together form a rotatable tubular component on the desktop. Since the three-way seat 3, the first diffuser 4, and the second diffuser 5 occupy a very small area of ​​the desktop when placed vertically, they provide a better user experience by not occupying the effective use space of the desktop.

[0070] The first end of the first diffuser 4 is rotatably connected to the first branch pipe 31 of the three-way connector 3. The interior of the first diffuser 4 is hollow, forming an air passage that extends along the central axis of the first diffuser 4. The outer wall of the first end of the first diffuser 4 is provided with a first air inlet screen 42 in an annular layout. A first fan 41 is provided inside the air passage at the first end of the first diffuser 4. The shell at the second end of the first diffuser 4 is provided with a first slit outlet 43 extending in a direction parallel to the central axis of the first diffuser 4. The air generated by the first fan 41 flows through the air passage to the second end and is emitted outward from the first slit outlet 43. The length of the first diffuser 4 is 'a', and the length of the first slit outlet 43 ranges from [0.3a, 0.6a]. The projection of the air inlet of the first fan 41 based on the central axis of the first diffuser 4 at least partially overlaps with the projection of the first air inlet screen 42 based on the central axis of the first diffuser 4.

[0071] The first end of the second diffuser 5 is rotatably connected to the second branch pipe 32 of the three-way connector 3. The interior of the second diffuser 5 is hollow, forming an air passage that extends along the central axis of the second diffuser 5 along its length. The outer wall of the first end of the second diffuser 5 is provided with a second air inlet screen 52 in an annular arrangement. A second fan 51 is provided inside the air passage at the first end of the second diffuser 5. The shell at the second end of the second diffuser 5 is provided with a second slit outlet 53 extending in a direction parallel to the central axis of the second diffuser 5. The air generated by the second fan 51 flows through the air passage to the second end and is emitted outward from the second slit outlet 53. The length of the second diffuser 5 is a, and the length of the second slit outlet 53 ranges from [0.3a, 0.6a]. The projection of the air inlet of the second fan 51 based on the central axis of the second diffuser 5 at least partially overlaps with the projection of the second air inlet screen 52 based on the central axis of the second diffuser 5.

[0072] Since the first diffuser 4 and the second diffuser 5 can rotate independently based on different branches of the three-way seat 3, airflow can be emitted in two different directions by adjusting the direction of the air outlets of the first diffuser 4 and the second diffuser 5.

[0073] Figure 4 and Figure 5 This is a schematic diagram illustrating the first usage state of the desktop fan with diffuser according to this utility model. Figure 4 and 5 As shown, when the three-way connector 3 is rotated so that the first diffuser 4 and the second diffuser 5 are perpendicular to the table, the first diffuser 4 and the second diffuser 5 can be rotated respectively (one emits to the left and the other emits to the right) so as to emit airflow in two different height directions and two different horizontal directions, which is conducive to indoor airflow. It is especially suitable for cooperating with air conditioning to circulate airflow around the room and enhance the regional cooling effect.

[0074] Figure 6 and Figure 7 This is a schematic diagram illustrating the second usage state of the desktop fan with a diffuser according to this utility model. Figure 6 and 7 As shown, when the three-way connector 3 is rotated so that the first diffuser 4 and the second diffuser 5 are parallel to the table, the first diffuser 4 and the second diffuser 5 can be rotated respectively (one emits upwards and the other emits downwards) so that airflow is emitted in two different height directions at the same height, which is beneficial to indoor airflow. It is especially suitable for airflow to surround the room in conjunction with air conditioning to enhance the regional cooling effect.

[0075] In summary, the purpose of this utility model is to provide a desktop fan with a diffuser that can output airflow in at least two directions simultaneously, which is beneficial to indoor air circulation. It is suitable for use as an air circulator fan, and the whole unit is very small, which improves the user experience.

[0076] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
