Description

Technical Field

[0001] This invention relates to the field of hair styling tools, and more particularly to a protective high-speed hair dryer. Background Technology

[0002] With the recent explosive growth in the home appliance market, various brands and manufacturers are working to create new, multi-functional, and improved hair dryers. In addition, hair dryers are one of the most widely used home appliances among current household consumers, and also one of the most popular hair styling tools. As a result, the market offers a wide variety of hair dryers with diverse functions.

[0003] In the current market, hair dryers are constantly being updated and replaced, with new types of hair dryers with different structures and functions emerging one after another. However, during the use of existing hair dryers, hair is easily sucked into the rear air inlet and clogs the air vent. In addition, the excessive variety of household appliances leads to a large number of appliances being left unused in the home. For example, hair dryers, dryers, quilt dryers, electric combs, and hair straighteners have similar and related functions, which take up a lot of living space and affect the comfort of life and the convenience of actual use.

[0004] Therefore, a technical problem that needs to be solved urgently by those skilled in the art is to enable consumers to smoothly and quickly dry and style their hair while using a hair dryer, especially for long-haired users, without hair being sucked into the air intake, effectively improving the comfort of the styling process and expanding the functionality of one device for multiple uses. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a protective high-speed hair dryer, which can effectively solve the problem of hair being sucked into the air inlet when blow-drying hair dryers on the market, and improve the comfort of hair styling process, and improve the practicality and reliability of the product technical solution.

[0006] The following technical solution is provided to solve this problem: A protective high-speed hair dryer includes a body, which includes a blower at the front of the body, an air inlet at the rear of the blower, and a handle tilted downwards at the front of the air inlet. The air inlet includes an outer wall and an air inlet inside the outer wall. An air inlet cover is provided on the air inlet. The inner end of the air inlet cover has evenly spaced air inlets. A filter cover is attached to the outer side of the air inlet cover. A filter support frame is movably attached to the inner end of the filter cover. A filter is fitted on the filter support frame. The filter cover is movably attached to the air inlet. The filter is movably attached to the filter support frame. The blower and the outer wall of the air inlet are integrally formed. The outer wall of the air inlet has a front-sloping connecting part. The connecting part and the outer wall of the air inlet are integrally formed. The connecting part and the handle are rotatably connected.

[0007] The main body has a multi-functional interface at its air outlet, which is equipped with a magnetic structure; a folding handle is located at the lower rear of the main body, and the handle has a rotating folding structure.

[0008] As an improvement, the multi-functional interface includes a card connector, which includes an air outlet end on the main body and an outer wall of the main body surrounding the air outlet end. The magnetic attraction structure includes an interface card slot between the air outlet end and the outer wall of the main body and a magnet at the bottom of the interface card slot.

[0009] The handle is equipped with a rotation limit structure, which restricts the rotation angle to 180 degrees. After the handle is rotated and folded, it is parallel to the air outlet on the main body.

[0010] The rotation limiting structure includes a rotation groove at the lower end of the connecting part and a rotation platform at the upper end of the handle. The rotation platform is rotatably connected to the rotation groove. The lower end of the connecting part has an inwardly recessed limiting groove with a 180-degree circumferential opening. The handle has a limiting platform with a limiting locking platform on its upper outer circumferential surface. When the handle rotates 180 degrees along the connecting part, the limiting locking platform engages with the other end of the opening groove, preventing the handle from rotating. It can then be rotated back to its original position. The retractable handle structure allows for 180-degree rotation and reset, and the retracted state ensures that the rotating part and the air outlet are parallel, effectively reducing storage space. Even without disassembling the external structure at the air outlet of the air outlet, the overall storage solution remains functional, adapting to the derivative features of multi-functional structures.

[0011] As an improvement, a multi-toothed fan shroud is connected to the card connector, and the rear interface of the multi-toothed fan shroud is provided with an iron inner ring I corresponding to the magnet on the card interface.

[0012] As an improvement, the card connector connects to the flat-mouth air outlet, and the flat-mouth air outlet end interface is equipped with an iron inner ring II corresponding to the magnet on the card interface.

[0013] The iron structure of the external interface corresponds to the magnet inside the air outlet for adsorption and limiting. Compared with the double magnet structure where both connecting parts are equipped with magnets, the interface of the external functional parts in this solution will not be attracted everywhere when placed in a box or other iron structure after the connection is disconnected. The placement and standby operation of external parts are more convenient and practical.

[0014] As an improvement, the air inlet is equipped with an identification bayonet, making installation easy and quick without twisting or slipping.

[0015] As an improvement, the air outlet is connected to the quilt dryer clip, the rear end interface of the quilt dryer clip is provided with the iron inner ring III of the magnet on the corresponding clip interface, and the front end of the quilt dryer clip is provided with the quilt dryer air outlet.

[0016] As an improvement, the air outlet of the quilt dryer is a cylindrical rod-shaped air outlet suitable for placement and operation in the quilt drying scenario. The rod-shaped air outlet is suitable for the need to release hot air over a large area when drying quilts or clothes in a large space.

[0017] As an improvement, a sealed connector for connecting a ventilation hose is provided at the front end of the air outlet of the quilt dryer. After the sealed connector and the ventilation hose are connected, the air outlet end of the ventilation hose is inserted into the quilt for drying and heating.

[0018] As an improvement, a protruding air inlet is provided on the upper part of the rear end of the main body, and the air inlet is laterally connected to the air inlet.

[0019] The horizontally penetrating air intake structure forms a cylindrical through hole, which matches the protruding structure of the outer air intake part to form large-diameter air intakes at both ends. Compared with the traditional rear-end air intake, the new design effectively increases the maximum air intake volume per unit time. With air intake from both sides, the airflow is smoother and the air volume is sufficient.

[0020] As an improvement, the air inlet is a circular through hole, and the air inlet cover is a cylindrical structure with openings at both ends. The air inlet cover is fitted inside the air inlet, and the filter support frame of the filter cover is fitted and attached to the outside of the air inlet cover.

[0021] It forms a two-layer filtration function of air inlet hood and filter screen, preventing hair from being inhaled while effectively filtering out dust particles and impurities in the inhaled airflow.

[0022] As an improvement, the filter cover and filter support frame are movably fitted and snapped together. The outer port of the filter cover is provided with an outwardly flared hood panel, which is made of semi-permeable plastic. The air inlet on the rear side of the hood panel is provided with a luminous marking symbol, which includes temperature and wind speed function settings. The inner side wall of the hood panel is provided with an inwardly protruding identification card head. The inner port of the filter cover is movably fitted and snapped together with the filter support frame, which is set as an annular cylindrical structure. The filter is a cylindrical mesh cover corresponding to the filter support frame, and the filter is slidably fitted and snapped onto the filter frame.

[0023] As an improvement, a magnet is provided in the middle of the air inlet channel, and the filter screen is made of iron.

[0024] As an improvement, a positioning step is provided on the inner side of the filter screen cover, and the rear end of the filter screen frame is movably engaged with the positioning step.

[0025] As an improvement, the filter frame includes at least three longitudinal support bars and two annular support bars connected above and below the support bars.

[0026] As an improvement, the outer port of the filter panel is an outwardly flared arc-shaped opening.

[0027] The beneficial effects of this invention are as follows: the integrated design enhances the tensile strength of the product during use; the protruding design of the air inlet greatly improves the scalability of the overall design and effectively enhances the adjustment of wind noise and speed, as well as user comfort; during operation, while ensuring air intake, it effectively prevents hair from being sucked in or tangled, thus improving the user experience and enhancing the product's practicality; the air inlet cover and filter are both movably attached to the air inlet, and after a period of use, the filter can be removed to clean the dust and debris, and then reinstalled for reuse while maintaining effective filtration, or a new filter can be replaced as needed, ensuring the hair dryer works efficiently for a long time.

[0042] like Figures 1-11 As shown, a protective high-speed hair dryer includes a body, which includes a blower 1 at the front of the body, an air inlet 2 at the rear of the blower, and a handle 3 tilted downwards at the front of the air inlet. The air inlet includes an outer wall 4 and an air inlet 5 inside the outer wall. An air inlet cover 6 is provided on the air inlet, and an evenly spaced air inlet hole 7 is provided at the inner end. A filter cover 30 is attached to the outer side of the air inlet cover, and a filter support frame 8 is movably attached to the inner end of the filter cover. A filter 9 is sleeved on the filter support frame. The filter cover 30 is movably attached to the air inlet, and the filter is movably attached to the filter support frame. The blower and the outer wall of the air inlet are integrally formed. The outer wall of the air inlet is provided with a front-sloping connecting part 10, which is integrally formed with the outer wall of the air inlet. The connecting part and the handle are rotatably connected.

[0043] The main body has a multi-functional interface 11 at its air outlet, and a magnetic structure 12 on the interface; a folding handle is provided at the lower rear of the main body, and the handle is a rotating folding structure.

[0044] While ensuring effective air intake, the filter is located outside the air inlet. This means that as air enters through the inlet, it passes through both the inner air inlet and the outer filter, effectively preventing hair from being sucked in or tangled, thus avoiding any impact on the user experience. The filter's mesh diameter is one-fifth to one-tenth of the air inlet diameter, effectively blocking hair and dust from being drawn in, thereby preventing damage to internal circuits or functional components, improving product usability and reliability, and reducing the failure rate. The filter cover and its support frame are movably attached to the air inlet. After a period of use, the filter cover, support frame, and filter can be removed individually as needed. Clean the dust and debris from the filter screen thoroughly, then reinstall it for repeated use to maintain effective filtration. The air inlet cover can be either tightly snapped onto the air outlet or bonded to it with high strength. Because the pores of the air inlet on the air inlet cover are much larger than those of the filter screen, many particles and impurities accumulate and get stuck on the filter screen. The filter screen only needs to be removed and cleaned frequently. The air inlet cover can be removed less frequently or not at all. It can be securely snapped or fixed in place using other methods such as bonding. This will not affect the overall filtration and cleaning. During the cleaning process, or if necessary, a new filter screen can be replaced. The operation and maintenance methods are flexible, ensuring the long-term efficient operation of the blower.

[0045] The universal interface ensures its functional expandability; the one-piece molded fixed connection between the air duct and the outer wall of the air inlet, as well as the one-piece molded fixed connection between the lower end of the outer wall of the air inlet and the handle, effectively improves connection stability and resistance to external forces compared to existing movable or separate structures. Especially when the hair dryer needs to repeatedly swing and adjust the blowing angle to speed up drying based on the dryness of the hair and the desired styling effect, the handle needs to be shaken back and forth to cause the entire body to swing rapidly and irregularly. The one-piece molded structure effectively ensures its strength to withstand forces, thereby reducing the actual failure rate and service life, and preventing the structure at the movable connection from falling off or loosening due to prolonged swinging force, which would affect work efficiency and user experience.

[0046] By designing the air inlet as an independent base unit, with the air duct and handle externally connected around it, this design scheme frees up design space for the air inlet, especially allowing for unlimited expansion of the rear and upper areas. This means the air inlet's dimensions can break free from the conventional design pattern where the dimensions of the air duct, handle, and air inlet are correspondingly limited. The air inlet's dimensions can be effectively increased according to desired effects, and the ratio between the air inlet and outlet can be appropriately improved. This increases the air inlet area, resulting in an intake volume per unit time that far exceeds the output volume required by the outlet. This reduces the intake pressure and wind speed on the filter, minimizing impact on the filter, reducing wind noise, and providing a quieter and more comfortable user experience.

[0047] Both the handle and the air outlet are located on the front side of the air inlet. When holding the handle, the weight of the air outlet on the front side of the handle and the air inlet on the rear side are distributed in a gravitational balance or near balance. In this way, when holding the handle for a long time, compared with the design where the air inlet is on the top side of the handle and the air outlet is on the front, the fatigue of holding the handle for a long time is effectively reduced, further improving the user experience.

[0048] The multi-functional interface includes a snap-fit ​​connector 13, which includes an air outlet end 14 on the main body and an outer wall 15 of the main body surrounding the air outlet end. The magnetic structure includes an interface slot 16 between the air outlet end and the outer wall of the main body and a magnet 17 at the bottom of the interface slot.

[0049] The handle is equipped with a rotation limit structure, which restricts the rotation angle to 180 degrees. After the handle is rotated and folded, it is parallel to the air outlet on the main body.

[0050] The rotation limiting structure includes a rotation groove 10-1 at the lower end of the connecting part and a rotation platform 3-1 at the upper end of the handle. The rotation platform is rotatably connected to the rotation groove. A recessed limiting groove 10-2 is provided at the lower end of the connecting part, and a 180-degree circumferential opening groove 10-3 is provided on the limiting groove. The handle is provided with the limiting platform 3-2, and a limiting platform 3-3 is provided on the outer circumferential surface of the upper end of the limiting platform. When the handle rotates 180 degrees along the connecting part, the limiting platform engages with the other end of the opening groove, preventing the handle from rotating. It can then be rotated back to its original position. This retractable handle structure allows for 180-degree rotation and reset, and the retracted state ensures the rotating part and the air outlet are parallel, effectively reducing storage space. Furthermore, the external structure at the air outlet of the air outlet does not affect the overall storage solution even without disassembly, adapting to the derivative functional characteristics of a multi-functional structure.

[0051] The snap-fit ​​connector connects to a multi-toothed fan shroud 18 or a flat-mouthed air outlet 20. The rear interface of the multi-toothed fan shroud is equipped with an iron inner ring I 19 corresponding to the magnet on the snap-fit ​​interface. The snap-fit ​​connector connects to the flat-mouthed air outlet 20. The flat-mouthed air outlet end interface is equipped with an iron inner ring II 21 corresponding to the magnet on the snap-fit ​​interface. The iron inner ring I and iron inner ring II of the external functional component correspond to the magnets in the snap-fit ​​interface for adsorption and limiting. Compared with the double magnet structure, the interface of the external functional component will not be adsorbed everywhere when placed in a box or other iron structure after being disconnected. The placement and standby operation of the external component are more convenient and practical.

[0052] The air inlet is equipped with an identification bayonet 22, which makes installation easy and secure without twisting or slipping.

[0053] In another embodiment of this solution, the air outlet is connected to the quilt dryer clamp 23, the rear end interface of the quilt dryer clamp is provided with an iron inner ring Ⅲ 24 corresponding to the magnet on the clamp interface, and the front end of the quilt dryer clamp is provided with the quilt dryer air outlet 25.

[0054] The air outlet of the quilt dryer is cylindrical, which is suitable for placing and acting on the quilt drying scene. The rod-shaped air outlet is suitable for the need to release hot air over a large area when drying quilts or clothes in a large space.

[0055] In another embodiment of this solution, a sealed connector for connecting a ventilation hose is provided at the front end of the air outlet of the quilt dryer. After the sealed connector and the ventilation hose are connected, the air outlet end of the ventilation hose is placed inside the quilt for drying and heating.

[0056] The upper rear end of the main body is provided with a protruding air inlet, and the air inlet is horizontally connected to the air inlet. The horizontally connected air inlet structure forms a cylindrical through hole, which matches the protruding structure of the outer air inlet to form a large-diameter air inlet located at both ends on the side. Compared with the traditional rear end air inlet, the new design effectively increases the maximum air volume per unit time. With air inlet from both sides, the airflow is smoother and the air volume is sufficient.

[0057] The air inlet is a circular through hole, and the air inlet cover is a cylindrical structure with openings at both ends. The air inlet cover is fitted inside the air inlet, and the filter support frame of the filter cover is fitted and attached to the outside of the air inlet cover.

[0058] It forms a two-layer filtration function of air inlet hood and filter screen, preventing hair from being inhaled while effectively filtering out dust particles and impurities in the inhaled airflow.

[0059] The filter cover and the filter support frame are movably fitted and snapped together. The outer port of the filter cover is provided with an outwardly flared hood panel 27, which is made of semi-transparent plastic. The air inlet on the rear side of the hood panel is provided with a light-emitting mark 26, which is a built-in LED indicator. The inner side wall of the hood panel is provided with an inwardly protruding identification card head 28. The inner port of the filter cover is movably fitted and snapped together with the filter support frame, which is set as an annular cylindrical structure. The filter is a cylindrical mesh cover corresponding to the filter support frame, and the filter slides and is snapped onto the filter frame.

[0060] The filter cover and filter support frame are movably fitted together and interlock with the air inlet cover at the air inlet. The filter and filter frame are both designed as annular cylinders and interlock with each other, making them easy to disassemble and install. The annular structure can achieve 360-degree circumferential filtration coverage, resulting in excellent filtration performance.

[0061] A magnet is installed in the middle of the air inlet channel, and the filter screen is made of iron. The filter screen cover is magnetically positioned and snapped in during installation to prevent it from falling off. With the help of the identification card head and identification card slot, it is simultaneously locked in the axial and circumferential directions to maintain the stability of its installation state, while also making it easy to pull out for cleaning.

[0062] A positioning step 29 is provided on the inner side of the filter screen cover, and the rear end of the filter screen frame is movably engaged on the positioning step; the filter screen is fitted onto the filter screen frame and pressed against the positioning step to achieve precise positioning, ensuring that the filter screen is engaged in the most suitable position, thereby effectively filtering dust and other debris; the filter screen frame includes at least three longitudinal support strips and two annular support strips connected above and below the support strips.

[0063] The outer end of the filter panel is an outward-expanding arc-shaped spout. The arc-shaped spout is designed as an open structure with a gradually expanding arc surface. The spout is cut outwards in a backward-forward direction, which effectively increases the actual area of ​​the air inlet, increases the amount of air flowing in per unit time, facilitates the smooth flow of air, and makes the appearance more beautiful.

[0064] In addition to the preferred embodiments described above, the present invention may have other embodiments. Those skilled in the art can make various changes and modifications based on the present invention, and all such changes and modifications should fall within the protection scope of the present invention as long as they do not depart from the spirit of the present invention.
