Description

Technical Field

[0001] This invention relates to a nozzle, specifically an anti-flipping nozzle, a hair dryer, and a method for using the nozzle, belonging to the field of hair dryer technology. Background Technology

[0002] Generally speaking, existing hair dryer nozzle technologies rely on the Coanda effect of curved surfaces to prevent hair from flipping. For example, traditional anti-flip nozzles use a semi-cylindrical design, utilizing the characteristic of airflow along a curved surface to attract hair strands to the nozzle surface and guide them downwards, thus reducing flyaways. This type of design avoids damage to hair from high-temperature styling and can achieve a smooth hair effect in cool air mode.

[0003] In the prior art, a hair dryer nozzle disclosed in patent CN220937114U includes a flow-dividing device. The flow-dividing device comprises partitions and connecting plates. Multiple partitions are connected by connecting plates, with the connecting plates located in the middle of the partitions. First and second air ducts are formed between the connecting plates and the partitions on both sides. Both the connecting plates and the partitions are arc-shaped. By setting the first and second air ducts on the flow-dividing device, hair can be drawn to the connecting plates by the airflow, allowing for faster drying. Furthermore, it can concentrate and maintain a high airflow rate, straightening the hair and preventing it from sticking up. However, in practical use, the following shortcomings still exist: 1. The airflow direction of the nozzle is fixed and cannot be flexibly adjusted according to the user's holding habits (left hand or right hand), resulting in inconvenience in operation; 2. The single airflow channel design is difficult to cover hair of different lengths or curliness. Short, choppy hairs are prone to falling out of the airflow adsorption range, resulting in the inability to completely solve the problem of hair sticking up. 3. Some nozzles require the use of combs or other accessories, which increases the complexity of user operation and equipment. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1, as Figures 1 to 9As shown, an anti-flipping hair dryer includes a hair dryer housing 2, a hair dryer support assembly, and a sliding assembly. The hair dryer support assembly is fitted inside the hair dryer housing 2. The area of ​​the hair dryer support assembly facing outwards has an arc-shaped structure. The sliding assembly is movably installed inside the hair dryer support assembly. A ventilation channel 10 is provided between the hair dryer support assembly and the inner wall of the hair dryer housing 2, allowing airflow to flow through the ventilation channel 10 between the hair dryer support assembly and the inner wall of the hair dryer housing 2, and then flow out from the upper opening of the hair dryer housing 2. The sliding assembly can move inside the hair dryer support assembly, which can block the ventilation channel 10 on one side of the hair dryer support assembly, so that the airflow can only flow out from one side of the hair dryer support assembly. This allows the user to choose the appropriate direction of airflow when using the hair dryer with their left or right hand to comb their hair. The sliding assembly includes two movable, mating inner sliding plates 4 of the nozzle. Each inner sliding plate 4 has a nozzle button 9 movably connected to its side, and the nozzle button 9 extends through the nozzle housing 2. When the nozzle button 9 on one side drives the connected inner sliding plate 4 to open the ventilation channel 10 on that side, the inner sliding plate 4 on the other side is pushed to abut against the inner wall of the nozzle housing 2, thereby blocking the ventilation channel 10. The sliding assembly can be moved by pushing the nozzle button 9, thereby blocking one side of the ventilation channel 10 of the nozzle support assembly with one of the inner sliding plates 4. In other words, by adjusting the direction of pressing the nozzle button 9, the ventilation channel 10 on either side can be blocked, thus controlling the airflow direction to meet different usage needs.

[0022] The nozzle support assembly of this invention has an arc-shaped structure facing outwards. A sliding component is movably housed within the nozzle support assembly. A ventilation channel 10 is provided between the nozzle support assembly and the inner wall of the nozzle housing. The airflow from the ventilation channel 10 flows along the arc-shaped structure, drawing long hair to the outside and thus covering short hair inside, thereby preventing flyaways. Furthermore, the sliding component includes two movable, mating nozzle inner sliding components 4. Each nozzle inner sliding component 4 has a nozzle button movably connected to its side, and the nozzle button movably extends through the nozzle housing. When the nozzle button on one side drives the connected nozzle inner sliding component 4, opening the ventilation channel 10 on that side, the nozzle inner sliding component on the other side is pushed against the inner wall of the nozzle housing 2, thus sealing the ventilation channel 10. The airflow direction can be switched using left and right buttons, adapting to left- and right-handed grip habits and improving operational convenience. The anti-flippery nozzle of this invention combines the Coanda effect to effectively absorb long hair and cover short, flyaway hair. No additional tools are required; airflow switching and hair styling can be completed with one hand. It is highly convenient to use and has a good anti-flippery effect.

[0023] Example 2: In addition to all the technical features in Example 1, this example also includes: the inner wall of the nozzle housing 2 is configured as an inner arc surface 21, which can serve as a guide; a support base 22 is provided at the bottom air inlet of the nozzle housing 2, and a plurality of base connecting ribs 23 are connected between the support base 22 and the bottom air inlet of the nozzle housing 2. The support base 22 can provide support for the nozzle bracket assembly, and when the airflow enters from the bottom air inlet of the nozzle housing 2, the support base 22 can guide the airflow and make the airflow flow through the gap between adjacent base connecting ribs 23, which can guide the airflow and reduce wind noise at the same time. Both sides of the nozzle housing 2 are provided with button sockets 24. The nozzle button 9 is movably inserted into the button sockets 24. The bottom of the nozzle housing 2 is provided with a nozzle magnet 1. The nozzle button 9 is limited and installed through the button sockets 24 to ensure that the nozzle button 9 can be pressed along the set path. The connected nozzle magnet 1 can easily magnetically connect the nozzle to the air outlet of the blower.

[0024] The nozzle support assembly includes an inner nozzle support 3 and an outer nozzle support 6. The bottom surface of the inner nozzle support 3 is connected to a parallel guide vane 31, and the upper surface of the outer nozzle support 6 is arc-shaped. A limiting post 32 is connected to the upper surface of the inner nozzle support 3. The limiting post 32 is symmetrically arranged along the central axis of the inner nozzle support 3. The opposite ends of the inner nozzle slide 4 are connected to slide connecting ribs 41. A hinge 5 is connected between the slide connecting ribs 41 of the two inner nozzle slides 4. A limiting movable groove 43 is opened on the body of the inner nozzle slide 4. The two inner nozzle slides 4 are combined together by the hinge 5, so that the two inner nozzle slides 4 can move synchronously. The inner nozzle slide 4 is locked in the limiting movable groove 43 at the limiting post 32, so that the inner nozzle slide 4 can only move left and right for adjustment.

[0025] The inner support bracket 3 of the air nozzle has multiple inner support screw holes 34. Screws 7 are threaded through the inner support screw holes 34, and the top of the screws 7 are threaded together with the outer support bracket 6 of the air nozzle. The inner support bracket 3 and the outer support bracket 6 of the air nozzle are fixed together by the screws 7. It should be noted that the outer support bracket 6 of the air nozzle has threaded seats that correspond one-to-one with the inner support screw holes 34. The inner support screw holes 34 are centrally symmetrically arranged on the inner support bracket 3 of the air nozzle.

[0026] Example 3: In addition to all the technical features in Example 1, this example also includes: a docking plate 42 connected to the middle part of the inner sliding plate 4 of the nozzle; a push-pull base plate 91 connected to the nozzle button 9; a mounting slot 44 opened on the lower surface of the docking plate 42; the body of the push-pull base plate 91 is movably locked in the mounting slot 44; a limiting protrusion 45 connected to the upper end of the mounting slot 44; a limiting push groove 46 connected to the inner end of the mounting slot 44; the front end of the push-pull base plate 91 abuts against the limiting push groove 46; and the body of the push-pull base plate 91 has... The limiting slot 92 and the limiting protrusion 45 are placed in the limiting slot 92. Through the alignment connection between the docking plate 42 and the push-pull base plate 91, when one of the nozzle buttons 9 is pressed, the front end of the push-pull base plate 91 on that side abuts against the limiting push groove 46, thereby driving the inner slide plate 4 of the nozzle to move. As the inner slide plate 4 of the nozzle moves, the nozzle button 9 on the other side is pushed out under the cooperation of the limiting protrusion 45 and the limiting slot 92. This ensures that the two nozzle buttons 9 cannot be pressed or pushed out at the same time, so that the user can control the direction of airflow.

[0027] The upper surface of the inner bracket 3 of the air nozzle is also connected to a button support rib 33. The push-pull base plate 91 is placed flat on the button support rib 33. A hemispherical protrusion 37 is integrally connected to the body of the button support rib 33. A hemispherical groove 93 is opened on the lower plate surface of the push-pull base plate 91. When the air nozzle button 9 is in the pushed-out state, the hemispherical protrusion 37 is locked in the hemispherical groove 93. The button support rib 33 can make the push-pull base plate 91 move horizontally in the placement slot 44. During the process of pushing out the air nozzle button 9, the hemispherical protrusion 37 is close to the lower plate surface of the push-pull base plate 91. Only when the air nozzle button 9 is pushed out to the end can the hemispherical protrusion 37 be locked in the hemispherical groove 93. When locked in place, a sound is produced, which can remind the user that the air direction adjustment has been completed.

[0028] The inner bracket 3 of the nozzle has inner bracket docking holes 35 on both sides, and the outer bracket 6 of the nozzle has outer bracket docking holes 63 on both sides. The nozzle shell 2 is snapped to both ends with nozzle decorative panels 8. The inner side of the nozzle decorative panel 8 is connected to the insertion hole seat 81. The inner bracket docking holes 35 and the outer bracket docking holes 63 are respectively set to correspond to the insertion hole seat 81. When installing the nozzle decorative panels 8 on both sides, the nozzle decorative panels 8 can be installed by aligning the docking holes with the insertion hole seat 81, ensuring that the nozzle decorative panels 8 can be positioned and installed.

[0029] The inner bracket 3 of the air nozzle is provided with inner bracket slots 36 on both sides of the frame, and the outer bracket 6 of the air nozzle is provided with outer bracket slots 64 on both sides of the frame. The inner side of the air nozzle decorative panel 8 is also connected with a locking block 82. The inner bracket slots 36 and the outer bracket slots 64 are respectively set to correspond to the locking blocks 82. When installing the air nozzle decorative panels 8 on both sides, the locking blocks 82 are aligned and snapped together to ensure that the air nozzle decorative panels 8 can be fixedly installed.

[0030] The upper surface of the arc-shaped structure of the nozzle outer bracket 6 is provided with a comb groove 61, and the upper surface of the nozzle outer bracket 6 is also connected with abutments 62 located on both sides of the comb groove 61. When the airflow flows along the inner arc surface 21 of the nozzle housing 2, the guide plate 31 works with the inner arc surface 21 to stabilize the airflow. The abutments 62 provide an air outlet between the nozzle outer bracket 6 and the nozzle housing 2, which facilitates the airflow. When the user combs their hair, the hair strands can be combed by the comb groove 61, and the airflow along the combing direction straightens the hair towards the air, thus preventing the hair from sticking up or becoming messy.

[0031] Example 4: This example provides a hair dryer, which includes the anti-flip nozzle from Example 1, and the air outlet of the hair dryer is connected to the anti-flip nozzle via magnetic attraction.

[0032] Example 5, such as Figure 10 and Figure 11 As shown, this embodiment provides a method for using a nozzle, including the anti-flying nozzle from Embodiment 1. The method for using this nozzle includes the following steps: S1. Press the nozzle button 9 on one side according to the holding direction to make the ventilation channel on that side open, and push the inner slide 4 of the nozzle on the other side to abut against the inner wall of the nozzle housing 2 so that the ventilation channel is blocked and closed.

[0033] Specifically, pressing the left or right nozzle button 9, depending on the grip direction, closes the airflow channel on the non-use side. Airflow inside the main unit flows from port A (arrow direction) to port C. The anti-flip nozzle assembly consists of multiple parts forming an internal cavity. Air flows out of the main unit, enters port B, and then splits into two channels flowing to port C. However, when the right nozzle button 9 is raised, it closes the channel, preventing airflow to port C. The other channel remains open, allowing airflow to flow from there along the arrow towards port C and blow onto the hair. Similarly, when the left nozzle button 9 is raised, it closes the channel, preventing airflow to port C. The other channel remains open, allowing airflow to flow from there along the arrow towards port C and blow onto the hair.

[0034] S2. The nozzle is close to the hair area, causing the airflow to adhere to the curved surface of the hair. Specifically, regardless of which side the airflow enters from, the airflow direction is along the curvature of the nozzle housing 2. Secondly, the purpose of controlling the airflow direction is to select the appropriate airflow direction when the user holds the machine with their left or right hand to comb their hair. Moving the hair dryer along the hair growth direction, the comb groove 61 is used to comb the hair strands, and at the same time, the airflow flowing along the combing direction makes the hair straighten in the direction of airflow, thereby preventing the hair from sticking up or becoming messy.

[0035] Working principle: Press the nozzle button 9 on the left or right side according to the holding direction to close the airflow channel on the non-use side. Place the nozzle close to the hair area to allow the airflow to draw the hair onto the curved surface. Move the hair dryer along the hair growth direction and use the comb groove 61 to comb the hair strands. At the same time, the airflow flowing along the combing direction will straighten the hair in the direction of air, thereby preventing the hair from sticking up or becoming messy.
