[0001] This utility model relates to the field of fan technology, and in particular to a handheld bladeless fan with adjustable air outlet. Background Technology

[0002] With the improvement of people's quality of life and the increasing pursuit of convenience and comfort, handheld bladeless fans have been widely used in daily life due to their safety, appearance and portability. Whether it is outdoor travel, office work and study, or indoor leisure, handheld bladeless fans have become a powerful tool for people to cool off in the summer.

[0003] Currently, most handheld bladeless fans on the market have fixed air vent sizes. Different groups of people have different airflow needs. The elderly and children usually prefer a gentle breeze, while young people need a larger airflow to cool down quickly after strenuous exercise. Existing bladeless fans with fixed air vent sizes cannot meet these diverse needs, which greatly limits the adaptability of handheld bladeless fans in various complex scenarios. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: the existing bladeless fans with fixed air vent size cannot meet such diverse needs, which greatly limits the adaptability of handheld bladeless fans in various complex scenarios. Therefore, this invention proposes a handheld bladeless fan with adjustable air vent.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A handheld bladeless fan with adjustable air outlet includes a fan body, an air outlet at the front end of the fan body, a circular plate fixedly installed inside the air outlet, a plurality of first air holes equally spaced around the surface of the circular plate, and a plurality of arc-shaped grooves equally spaced around the side wall of the air outlet.

[0007] The air outlet is provided with a circular partition, and multiple second air holes are equidistantly opened on the circumference of the partition. A rotating ring is fixedly sleeved on the side of the partition, and multiple mounting holes are opened at the edge of the rotating ring. An elastic plate is fixedly installed in each of the multiple mounting holes, and a sliding block is fixedly installed at one end of each of the multiple elastic plates. The rotating ring is rotatably set in the air outlet, and the multiple sliding blocks are slidably inserted into multiple sliding grooves.

[0008] Preferably, the circular plate has a mounting hole at its center, the partition plate has a circular hole at its center, mounting blocks are symmetrically fixed inside the mounting hole, and limit blocks are installed on both mounting blocks by means of elastic components. A ring is fixedly installed on the back of the partition plate, the central axis of the ring coincides with the central axis of the circular hole, and multiple limit grooves are equidistantly formed on the circumference of the ring surface, with the two limit blocks respectively inserted into two of the limit grooves.

[0009] Preferably, each of the two mounting blocks has a mounting groove on one side opposite to the partition, and a moving hole connected to the mounting groove is provided at the end of the mounting block near the partition. The elastic component includes a moving block that is horizontally slidably installed in the mounting groove, a telescopic spring that is fixedly installed on the moving block, and a moving rod that is horizontally slidably installed in the moving hole. The end of the telescopic spring away from the moving block is fixedly connected to the inner wall of the mounting groove, and the two ends of the moving rod are fixedly connected to the moving block and the limiting block, respectively.

[0010] Preferably, a connecting plate is fixedly installed between the two movable blocks, and a top plate is fixedly installed in the middle of the connecting plate.

[0011] Preferably, the back of the fan body has a hanging hole, which is L-shaped.

[0012] Preferably, the fan body and the circular plate are integrally formed, and the rotating ring and the partition are integrally formed.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting a fixed circular plate with a first air hole and a rotatable partition with a second air hole inside the air outlet, and with the sliding fit structure of the rotating ring and the slide groove, the overlapping area of ​​the first air hole and the second air hole can be adjusted by rotating the partition, thereby flexibly changing the effective ventilation area of ​​the air outlet and realizing the adjustment of the air volume. This solves the problem that the air outlet of the existing handheld bladeless fan is fixed and cannot adapt to the needs of different people and different scenarios, and significantly improves the adaptability of the product.

[0015] 2. The mounting block at the center of the circular plate is connected to the limiting block through an elastic component, and multiple limiting grooves are provided on the ring on the back of the partition. When the partition rotates to the target position, the limiting block is locked into the limiting groove under the action of the elastic component, which can stably lock the position of the partition and prevent the partition from rotating accidentally due to vibration or accidental contact during use. This ensures the stability after air volume adjustment and improves the reliability of the product. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1 A handheld bladeless fan with adjustable air outlet includes a fan body 1. The front end of the fan body 1 has an air outlet. A circular plate 2 is fixedly installed inside the air outlet. Multiple first air holes are equidistantly opened on the circumference of the surface of the circular plate 2. Multiple arc-shaped sliding grooves 3 are equidistantly opened on the circumference of the side wall of the air outlet. A circular partition 4 is provided inside the air outlet. Multiple second air holes are equidistantly opened on the circumference of the surface of the partition 4. A rotating ring 5 is fixedly sleeved on the side of the partition 4. Multiple mounting holes are opened on the edge of the rotating ring 5. An elastic plate 6 is fixedly installed in each of the multiple mounting holes. A sliding block 7 is fixedly installed at one end of each of the multiple elastic plates 6. The rotating ring 5 is rotatably set inside the air outlet. The multiple sliding blocks 7 are slidably inserted into the multiple sliding grooves 3 respectively.

[0026] Reference Figure 3 and Figure 6The rotating ring 5 is fixedly connected to the partition 4 and rotates synchronously with the partition 4. The elastic plate 6 has elastic deformation capability, and the sliding block 7 at one end is inserted into the slide groove 3. The rotating ring 5 is guided to rotate along the fixed track by the arc track of the slide groove 3, and the elastic force of the elastic plate 6 makes the sliding block 7 fit tightly against the inner wall of the slide groove 3, so as to avoid loosening or deviation during rotation and ensure that the adjustment process is stable and smooth.

[0027] The fan body 1 provides support for the overall structure, and its front air outlet is the channel for air output. The circular plate 2 is fixed inside the air outlet, and the first air hole on its surface is the basic channel for air output. The partition plate 4 is set parallel to the circular plate 2, and the second air hole on its surface cooperates with the first air hole. By rotating the partition plate 4, the overlapping area of ​​the two can be changed to realize the air volume adjustment. The larger the overlapping area, the larger the effective ventilation area and the larger the air volume, and vice versa. This solves the problem of the fixed air outlet of the existing handheld bladeless fan and its inability to adapt to the needs of different people and different scenarios, and significantly improves the adaptability of the product.

[0028] Reference Figure 4 and Figure 7 The circular plate 2 has a mounting hole in its center and the partition plate 4 has a circular hole in its center. Mounting blocks 8 are symmetrically fixed inside the mounting holes. Limiting blocks 9 are installed on both mounting blocks 8 through elastic components. A circular ring 10 is fixedly installed on the back of the partition plate 4. The central axis of the circular ring 10 coincides with the central axis of the circular hole. Multiple limiting grooves 11 are equidistantly opened on the circumference of the surface of the circular ring 10. Two limiting blocks 9 are respectively inserted into two of the limiting grooves 11.

[0029] The mounting holes of the circular plate 2 provide a fixed space for the mounting block 8. The mounting block 8 is used to fix the elastic component. The elastic component provides elastic driving force for the limiting block 9. The circular ring 10 rotates synchronously with the partition 4. The limiting groove 11 on its surface cooperates with the limiting block 9. When the partition 4 rotates to the position corresponding to the target air volume, the limiting block 9 is inserted into the limiting groove 11 under the action of the elastic component to lock the position of the partition 4, preventing the partition 4 from rotating accidentally due to vibration or accidental contact during use, and ensuring stable air volume.

[0030] Each of the two mounting blocks 8 has a mounting groove on one side opposite to the other. The end of the mounting block 8 near the partition plate 4 has a moving hole that communicates with the mounting groove. The elastic component includes a moving block 12 that is horizontally slidably installed in the mounting groove, a telescopic spring 13 that is fixedly installed on the moving block 12, and a moving rod 17 that is horizontally slidably installed in the moving hole. The end of the telescopic spring 13 away from the moving block 12 is fixedly connected to the inner wall of the mounting groove. The two ends of the moving rod 17 are fixedly connected to the moving block 12 and the limiting block 9, respectively. A connecting plate 14 is fixedly installed between the two moving blocks 12. A top plate 15 is fixedly installed in the middle part of the connecting plate 14.

[0031] The mounting slot of mounting block 8 provides space for the movable block 12 and the telescopic spring 13 to be accommodated and slide. The moving hole provides a guide for the moving rod 17 to ensure that it moves horizontally. When the telescopic spring 13 is in its natural state, the moving block 12 and the moving rod 17 push the limiting block 9 into the limiting groove 11 to achieve locking. When it is necessary to rotate the partition 4, the top plate 15 can be pushed with a finger, which simultaneously drives the two movable blocks 12 to move through the connecting plate 14, driving the movable blocks 12 to compress the telescopic spring 13. The moving rod 17 moves synchronously with the movable block 12, driving the limiting block 9 to disengage from the limiting groove 11 and unlocking it. At this time, the partition 4 can rotate freely.

[0032] Reference Figure 2 The back of the fan body 1 has a hanging hole 16. The hanging hole 16 is L-shaped and can be used to attach a lanyard, keychain or other items, making it convenient for users to hang and carry the fan in outdoor travel, office or study scenarios, reducing the burden of holding it. At the same time, when not in use, the fan can be hung up and stored through the hanging hole 16 to save space.

[0033] Reference Figure 5 The fan body 1 and the circular plate 2 are integrally formed, and the rotating ring 5 and the partition plate 4 are integrally formed. The integrally formed structure reduces the assembly gaps and connection points between components, improves the stability and sealing of the overall structure, and reduces the risk of components loosening or falling off due to long-term use. At the same time, it reduces assembly steps, which helps to improve production efficiency and reduce costs.

[0034] In this invention, the overlapping area of ​​the two can be changed by rotating the partition 4, thereby adjusting the air volume. The larger the overlapping area, the larger the effective ventilation area and the larger the air volume, and vice versa. This solves the problem that the air outlet of the existing handheld bladeless fan is fixed and cannot adapt to the needs of different people and different scenarios, and significantly improves the adaptability of the product.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
