Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment, and more specifically, to a fan with a V-shaped nozzle. Background Technology

[0002] Currently, traditional desktop fans on the market output airflow through large fan blades connected to the motor output shaft, causing the coaxial guide grid to rotate and thus spread the airflow in different directions. However, this structure is usually large and occupies a lot of desktop space.

[0003] While bladeless fans effectively reduce size, the direction of the airflow is usually unidirectional. The direction of the airflow can usually only be changed by rotating the chassis, which has little effect on the airflow inside the room and makes it difficult to promote indoor air circulation.

[0004] Therefore, this invention provides a fan with a V-shaped nozzle section. Utility Model Content

The airflow is diverted from the three-way air distribution seat and reaches the second end of the diffuser, and is emitted outward from the air outlet of the diffuser.

[0011] Preferably, it includes a first diffuser and a second diffuser, the first diffuser and the second diffuser being symmetrical based on the three-way air distribution seat.

The lower end of the lifting rod 1 is connected to the base. The fan part 2 is connected to the upper end of the lifting rod 1, and a fan 21 for generating airflow is built into the fan part 2. The V-shaped nozzle part includes a three-way air distribution seat 3 and two diffusers. The main pipe of the three-way air distribution seat 3 is rotatably connected to the fan part 2. The first end of the diffuser is rotatably connected to the two branch pipes of the three-way air distribution seat 3. As the second end of the diffuser extends away from the three-way air distribution seat 3, it also extends away from the fan part 2. The airflow is diverted from the three-way air distribution seat 3 and reaches the second end of the diffuser, and is emitted outward from the diffuser's outlet.

[0052] In a preferred embodiment, a first diffuser 4 and a second diffuser 5 are included, the first diffuser 4 and the second diffuser 5 being symmetrical about the three-way air distribution seat 3, but not limited thereto.

[0053] In a preferred embodiment, when the air outlets of the first diffuser 4 and the second diffuser 5 both emit airflows away from the fan unit 2, the airflows emitted by the first diffuser 4 and the second diffuser 5 converge in front of the three-way air distribution seat 3 away from the fan unit 2, but this is not a limitation.

[0054] In a preferred embodiment, the air outlet is located on the side of the diffuser away from the fan section 2, but this is not a limitation.

[0055] In a preferred embodiment, the first diffuser 4 and the second diffuser 5 are cylindrical, and a first straight air passage 42 and a second straight air passage 52 are formed inside the first diffuser 4 and the second diffuser 5, respectively, but this is not a limitation.

[0056] In a preferred embodiment, the housing at the second end of the first diffuser 4 is provided with a first slit outlet 41 extending in a direction parallel to the central axis of the first diffuser 4, and the housing at the second end of the second diffuser 5 is provided with a second slit outlet 51 extending in a direction parallel to the central axis of the second diffuser 5, but this is not a limitation.

[0057] In a preferred embodiment, the length of the first diffuser 4 is a, the length of the first slit outlet 41 ranges from [0.5a, 0.9a], the length of the second diffuser 5 is a, and the length of the second slit outlet 51 ranges from [0.5a, 0.9a], but is not limited thereto.

[0058] In a preferred embodiment, the three-way air distribution seat 3 is provided with an air distribution wall 31 inside. The air distribution wall 31 includes an air distribution tip and guide slopes located on both sides. Air flows through the guide slopes of the air distribution tip and is guided to the first diffuser 4 and the second diffuser 5 respectively, but is not limited thereto.

[0059] The specific embodiments of this utility model are as follows:

[0060] Continue to refer to Figures 1 to 5 The lower end of the lifting rod 1 of the fan with a V-shaped nozzle section of this utility model is connected to the base. The fan section 2 is connected to the upper end of the lifting rod 1, and the fan section 2 has a built-in fan 21 that generates airflow. The V-shaped nozzle section includes a three-way air distribution seat 3, a first diffuser 4 and a second diffuser 5. The main pipe of the three-way air distribution seat 3 is rotatably connected to the fan section 2. The first diffuser 4 and the second diffuser 5 each have a first end connected to the three-way air distribution seat 3 and a second end away from the three-way air distribution seat 3. The first end is rotatably connected to two branch pipes of the three-way air distribution seat 3. As the second end extends away from the three-way air distribution seat 3, it also extends away from the fan section 2. The airflow is split from the three-way air distribution seat 3 and reaches the second end of the diffuser, and is emitted outward from the outlet of the diffuser. The first diffuser 4 and the second diffuser 5 are symmetrical about the three-way air distribution seat 3. The airflow emitted by the first diffuser 4 and the airflow emitted by the second diffuser 5 converge in front of the three-way air distribution seat 3 away from the fan section 2. The air outlet is located on the side of the diffuser away from the fan section 2. The first diffuser 4 and the second diffuser 5 are cylindrical, and the first diffuser 4 and the second diffuser 5 respectively form a first straight air passage 42 and a second straight air passage 52 inside. The housing at the second end of the first diffuser 4 has a first slit air outlet 41 extending in a direction parallel to the central axis of the first diffuser 4, and the housing at the second end of the second diffuser 5 has a second slit air outlet 51 extending in a direction parallel to the central axis of the second diffuser 5. The length of the first diffuser 4 is a, and the length of the first slit air outlet 41 ranges from [0.5a, 0.9a]. The length of the second diffuser 5 is a, and the length of the second slit air outlet 51 ranges from [0.5a, 0.9a]. The three-way air distribution seat 3 has an air distribution wall 31 inside. The air distribution wall 31 includes an air distribution tip and guide slopes located on both sides. The air flows through the guide slopes of the air distribution tip and is guided to the first diffuser 4 and the second diffuser 5 respectively.

[0061] When the three-way connector 3 is rotated so that the first diffuser 4 and the second diffuser 5 are parallel to the tabletop, the first diffuser 4 and the second diffuser 5 can be rotated separately (one emits air upwards, and the other emits air downwards) to produce airflows at two different heights from the same height. This facilitates indoor air circulation and is especially suitable for coordinating with air conditioning to create airflow around the room, enhancing the cooling effect of the area. At this time, refer to... Figure 5When both the first diffuser 4 and the second diffuser 5 are blowing air forward (the air outlets of the first diffuser 4 and the second diffuser 5 both emit airflow in a direction away from the fan unit 2), the airflow emitted by the first diffuser 4 and the airflow emitted by the second diffuser 5 converge in front of the three-way air distribution seat 3 away from the fan unit 2. In this area, the user can simultaneously enjoy the airflow emitted by the first diffuser 4 and the airflow emitted by the second diffuser 5 in the horizontal direction, thus improving the user experience.

[0062] Furthermore, when the three-way connector 3 is rotated so that the first diffuser 4 and the second diffuser 5 are perpendicular to the tabletop, the first diffuser 4 and the second diffuser 5 can be rotated separately (one emitting air to the left and the other to the right) to generate airflow in two different horizontal directions at two different heights. This facilitates indoor air circulation and is especially suitable for coordinating with air conditioning to circulate air around the room, enhancing the cooling effect of the area. Similarly, if both the first diffuser 4 and the second diffuser 5 are blowing air forward, the airflow emitted by the first diffuser 4 and the second diffuser 5 converge in front of the three-way connector 3 away from the fan unit 2. In this area, the user can simultaneously enjoy the airflow emitted by the first diffuser 4 and the second diffuser 5 in the vertical direction, improving the user experience.

[0063] Figure 6 This is a top view of the second type of fan with a V-shaped nozzle according to this utility model. Figure 6 As shown, the difference between the second type of fan with a V-shaped nozzle and the first type of fan with a V-shaped nozzle lies in the shape of the diffuser. In the second type of fan with a V-shaped nozzle, the first diffuser 4 and the second diffuser 5 are horn-shaped, and the first diffuser 4 and the second diffuser 5 respectively form a first curved air passage 43 and a second curved air passage 53 inside. The housing at the second end of the first diffuser 4 has a first slit outlet 41 extending parallel to the extension direction of the first diffuser 4, and the housing at the second end of the second diffuser 5 has a second slit outlet 51 extending parallel to the extension direction of the second diffuser 5. The length of the first diffuser 4 is 'a', and the length of the first slit outlet 41 ranges from [0.5a, 0.9a]. The length of the second diffuser 5 is 'a', and the length of the second slit outlet 51 ranges from [0.5a, 0.9a]. Compared with the first type of fan with a V-shaped nozzle, the second type of fan with a V-shaped nozzle can provide a more circumferential airflow, improving the user experience. Based on this, diffusers of other shapes can also be used as needed.

[0064] In summary, the purpose of this utility model is to provide a fan with a V-shaped nozzle that can output airflow in at least two directions simultaneously, which is beneficial to indoor air circulation and suitable for use as an air circulator. It also enhances the airflow convergence effect at the front of the fan to increase local wind power and improve the user experience.

[0065] 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 or substitutions should be considered within the protection scope of the present invention.
