Description

Technical Field

[0001] This utility model belongs to the field of hair dryer technology, specifically relating to the accessory structure of a high-powered fan, and more particularly to a high-powered fan nozzle with adjustable diameter. Background Technology

[0002] High-powered fans (such as high-pressure blowers and industrial high-powered fans) are widely used in homes, industries, and outdoor settings due to their high airflow intensity and rapid drying efficiency. Most existing high-powered fans have fixed nozzles with non-adjustable outlet diameters. When users require different airflow speeds or coverage areas (such as concentrated strong airflow for quickly drying a localized area, or enlarged outlet diameters for large-area heat dissipation), it is necessary to replace them with nozzles of different diameters.

[0003] This replaceable design has obvious drawbacks: on the one hand, the extra nozzle accessories increase the burden of carrying, especially when used outdoors, they need to be stored separately and are easily lost due to bumps or negligence; on the other hand, the replacement process requires stopping use and manually installing and removing the nozzles, which is cumbersome and affects the continuity of use.

[0004] Meanwhile, existing high-powered fan nozzles only have a simple air guiding function and lack additional practical functions. In everyday use scenarios (such as indoor ventilation and clothes drying), users often hope that the airflow can carry a pleasant fragrance to improve the user experience or purify the air, but existing nozzles cannot meet this need and must be used with aromatherapy products, which increases the cost of use and the inconvenience of operation.

[0005] Therefore, there is an urgent need for a high-powered fan nozzle that can achieve diameter adjustment without replacing parts and integrates additional functions, in order to solve the problems of inconvenience in carrying, easy loss and low replacement efficiency in the existing technology. Utility Model Content

[0006] This invention aims to overcome the shortcomings of existing high-powered fan nozzles with fixed diameters and the need for frequent replacement of parts, and provides a high-powered fan nozzle with an adjustable diameter that is simple in structure and easy to operate, enabling rapid adjustment of the nozzle diameter, while integrating additional functions to enhance practicality.

[0007] The above-mentioned objective of this utility model is achieved through the following technical solution: an adjustable nozzle for a high-powered fan, comprising a cylindrical body, the rear end of which is used to connect with the air outlet of a high-powered fan, and a plurality of adjusting plates provided inside the cylindrical body, the edges of which are stacked in pairs, and the rear ends of the adjusting plates are fixed to the rear end of the cylindrical body, while the front ends are free ends (not fixed to the cylindrical body), together forming an adjustable nozzle; the adjusting plates are provided with a gradually changing slope, and the cylindrical body is provided with a through hole at the position corresponding to the gradually changing slope, and an adjusting ring is fitted outside the cylindrical body, the inner wall of which is provided with a protrusion that passes through the through hole and presses against the gradually changing slope.

[0008] Furthermore, the gradually changing slope can be a slope groove structure that is concave within the adjusting plate, or a slope protrusion structure that is convex outside the adjusting plate.

[0009] Furthermore, the cylinder is cone-shaped, with its front port diameter smaller than its rear port diameter, to meet the requirements of centralized wind power output.

[0010] Furthermore, the outer surface of the adjustment ring is provided with anti-slip textures (such as straight stripes, grid patterns, dot patterns, etc.) to increase hand friction and facilitate rotation operation.

[0011] Furthermore, the cylinder is provided with an aromatherapy box, the lower part of which extends into the interior of the cylinder, and the extended part is provided with a fragrance dispersing hole; the interior of the aromatherapy box is used to place solid fragrances or aromatherapy tablets, and the fragrance can be carried and diffused when the fan blows out.

[0012] Furthermore, the aromatherapy box is detachably connected to the cylinder body.

[0013] Furthermore, the top of the aromatherapy box is equipped with an openable and closable lid (such as a snap-on or threaded lid) for easy opening and replacement of fragrances.

[0014] Furthermore, the connection method between the rear end of the cylinder and the exhaust port of the high-powered fan can be any one of the following: sleeve connection, threaded connection, magnetic connection, or snap-fit ​​connection, to achieve quick assembly and disassembly.

[0015] The working principle of this utility model:

[0016] In use, by rotating the adjusting ring on the outside of the cylinder, the protrusion on the inner wall of the adjusting ring moves along the through hole of the cylinder, allowing the protrusion to slide on the gradually changing slope surface of the adjusting plate:

[0017] As the protrusion moves to a higher part of the slope, the pressure exerted by the protrusion on the adjusting plate increases, forcing the front end of the adjusting plate to converge towards the center, thus reducing the diameter of the expandable air nozzle.

[0018] As the protrusion moves towards the lower part of the slope, the resistance of the protrusion to the adjusting plate decreases, and the front end of the adjusting plate opens outward under its own elasticity, increasing the diameter of the expandable air nozzle.

[0019] The above operations allow for continuous adjustment of the nozzle diameter without the need to replace parts.

[0020] The advantages of this utility model compared with the prior art are:

[0021] 1. Adjustable diameter, no need to replace parts: Through the cooperation structure of the adjustment ring and adjustment plate, the diameter can be continuously adjusted directly on the same nozzle, eliminating the need for additional nozzle parts, avoiding inconvenience in carrying and loss, and making operation convenient (simply rotate to adjust).

[0022] 2. Integrated aromatherapy function: With the built-in aromatherapy box design, the fragrance can be diffused while the air is blown out, enhancing the user experience (such as adding hair care fragrance when drying hair, or improving the smell of the air when ventilating a room).

[0023] 3. Simple structure and strong adaptability: The overall components are few and easy to assemble. The rear end of the cylinder supports multiple docking methods and can be adapted to different models of high-power fans. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0034] Reference Figures 1 to 7 This utility model discloses an adjustable-diameter high-powered fan nozzle, which mainly includes:

[0035] Cylinder 1: Made of weather-resistant plastic, it is cone-shaped with a front port diameter smaller than the rear port diameter to meet the needs of concentrated wind power output; the rear end of cylinder 1 is used to connect with the air outlet of a high-power fan, with a reserved installation position for a suitable connection structure.

[0036] Adjustment plate 2: Multiple elastic plastic plates are used. The rear end of the adjustment plate 2 is fixed on the inner wall of the rear end of the cylinder 1 on a pre-set step, and the front end is a free end. The side edges of the multiple adjustment plates 2 are stacked on each other to form a ring-shaped scalable structure, which together form the air outlet of the nozzle.

[0037] Gradual slope 3: integrally formed on the outer wall of the adjusting plate 2, extending along the length of the adjusting plate; in this embodiment, a slope groove structure concave to the adjusting plate is adopted, or a slope protrusion structure convex to the adjusting plate can be adopted according to assembly requirements. Its core is to form a force-bearing surface with continuously varying height along the width direction of the adjusting plate.

[0038] Through hole 4: It is a long strip-shaped through hole opened at the position of the height gradient slope 3 of each adjusting plate 2 on the cylinder 1. Its length is adapted to the extension range of the height gradient slope 3, and its width is adapted to the size of the adjustment ring protrusion. It is used to allow the protrusion of the adjustment ring to pass through and move along the slope.

[0039] Adjusting ring 5: Made of wear-resistant plastic, it is fitted on the outside of the cylinder 1 and can rotate flexibly around the cylinder axis; the outer surface of the adjusting ring 5 is provided with uniformly distributed anti-slip textures 10, which can be straight stripes, grid patterns or dot patterns, etc., to increase the friction between the hand and the adjusting ring, making it convenient for the user to rotate; the inner wall of the adjusting ring 5 is provided with protrusions 6 corresponding to the number of adjusting plates at the position of the through hole 4. After passing through the through hole 4, the protrusions press against the gradually changing slope surface 3, ensuring that the protrusions can effectively slide along the slope surface when the adjusting ring is rotated.

[0040] Aroma diffuser box 7: Made of lightweight and durable material, it is detachably connected to the side wall of cylinder 1 via a snap-fit ​​connection (or other detachable structures such as threaded connection), making it easy to disassemble, clean or replace; The lower part of aroma diffuser box 7 extends into the interior of cylinder 1, and the extended part has multiple fragrance dispersing holes 8 to ensure that the fragrance can be smoothly carried and diffused when the fan blows out; The top of aroma diffuser box 7 has an openable lid 9, which adopts a snap-fit ​​or threaded connection structure, and solid fragrance 11 or aroma tablets can be placed inside the aroma diffuser box after opening.

[0041] Assembly and use of this utility model:

[0042] During assembly, first fix the rear ends of the multiple adjustment plates 2 to the inner wall of the rear end of the cylinder 1, ensuring that the edges of each adjustment plate overlap and are evenly distributed; then install the adjustment ring 5 to the position of the corresponding through hole 4, so that the protrusion 6 on the inner wall of the adjustment ring is aligned and passes through the through hole 4, ensuring that the protrusion can make close contact with the gradually changing slope surface 3 of the adjustment plate 2 without affecting the rotation of the adjustment ring; finally, install the aromatherapy box 7 at the preset position on the side wall of the cylinder 1 through the snap-fit ​​structure to complete the overall assembly.

[0043] In use: Depending on the structure of the fan's outlet, select any one of the following methods: socket connection, threaded connection, magnetic connection, or snap-fit ​​connection, and securely connect the rear end of the cylinder 1 to the fan's outlet. If it is necessary to reduce the nozzle diameter, rotate the adjusting ring 5, causing the inner wall protrusion 6 to slide upwards along the gradually changing slope 3. The pressure of the protrusion on the adjusting plate 2 gradually increases, forcing the front end of the adjusting plate to converge towards the center (e.g., Figure 6 , Figure 7 Adjust until the desired nozzle diameter is reached; if the nozzle diameter needs to be enlarged, rotate the adjusting ring 5 in the opposite direction, and the protrusion 6 slides down the gradually changing slope 3, gradually reducing the pressure of the protrusion on the adjusting plate 2. The front end of the adjusting plate naturally opens outward under its own elasticity (as shown). Figure 1 , Figure 4 and Figure 5 Once the target diameter is reached, the rotation stops. To use the aromatherapy function, open the lid 9 of the aromatherapy box 7, put in an appropriate amount of solid fragrance or aromatherapy tablets, and then close the lid. When the fan starts and blows air, the airflow passes through the fragrance dispersing holes 8 of the extended part of the aromatherapy box, carrying the fragrance of the fragrance and blowing it out from the air outlet of the nozzle to achieve the aromatherapy effect. When it is necessary to replace the fragrance or clean the aromatherapy box, simply remove the aromatherapy box from the cylinder. The operation is convenient.
