Description

Technical Field

[0001] This invention belongs to the field of hair dryer technology, specifically relating to a hair dryer that prevents direct hot air blowing. Background Technology

[0002] Hair dryers are a common household appliance with drying functions.

[0003] The hair dryer includes a fan assembly and a heating assembly. The fan assembly draws air into the body, and the air is heated by the heating assembly to achieve the purpose of drying.

[0004] Currently, existing hair dryers typically require constant maneuvering of the hair and repeated blowing with hot air to improve efficiency. However, this often results in messy hair after drying, making combing difficult. Additionally, the high-volume hot air can transfer heat from the hair to the scalp, potentially causing burns. If a lower-volume, slower hot air setting is used, drying time is longer and efficiency is lower. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a hair dryer that prevents direct hot air blowing.

[0006] The technical solution adopted to solve the above technical problems is: a hair dryer with heat protection against direct heat blowing, including a hollow handle, a storage shell fixed to the top side wall of the hollow handle, an opening and closing pressing component inside the storage shell, two accordion hoses connected through the top of the hollow handle, the top of the accordion hoses connected to the bottom of the opening and closing pressing component, symmetrically arranged airflow separating shells rotatably installed above the opening and closing pressing component, heat protection against direct heat blowing connected through the top of each airflow separating shell, the heat protection against direct heat blowing components on both sides being symmetrically arranged, the opening and closing pressing component driving the heat protection against direct heat blowing components on both sides to open and close, achieving heat protection against heat blowing while combing hair, and the heat protection against direct heat blowing components on both sides rotating forward synchronously to switch the blowing mode; The heat-proof direct-blowing assembly includes a rectangular housing, a pressing handle, a ventilation comb, a heat insulation plate, an airflow distribution plate, and a thermoelectric wire mesh.

[0007] Preferably, the heat insulation plate is vertically fixed inside the rectangular shell cavity, dividing the inner cavity of the rectangular shell into a hot air cavity and a cold air cavity. A hot air inlet is opened at the bottom end of the hot air cavity, and a cold air inlet is opened at the bottom end of the cold air cavity. A plurality of hot air outlets are opened through one side of the outer wall of the hot air cavity, and a cold air outlet is opened through one side of the outer wall of the cold air cavity. The cold air outlet and the hot air outlet are located on the same side. Ventilation openings are opened through both sides of the rectangular shell, and the ventilation openings correspond to the positions of the hot air outlets on the other side of the rectangular shell.

[0008] Preferably, the airflow distribution plate and the thermoelectric wire mesh are vertically arranged and installed inside the hot air cavity. The airflow distribution plate is close to the hot air outlet. The airflow distribution plate and the thermoelectric wire mesh are both located between the hot air outlet and the hot air inlet. The pressing handle is fixedly installed on the front side wall of the rectangular shell. A ventilation comb is inserted and fixedly connected to the outer edge of the cold air outlet.

[0009] Through the above technical solution, the airflow enters the cavity of the rectangular shell through the hot air inlet and the cold air inlet, respectively entering the hot air cavity and the cold air cavity. The airflow entering the hot air cavity first passes through the thermoelectric wire mesh and then through the airflow distribution plate, making the airflow speed and temperature distribution more uniform. Finally, the hot air flows out from the hot air outlet. The unheated, low-temperature airflow entering the cold air cavity flows from the cold air outlet to the ventilation comb. The ventilation comb guides the cold air above the scalp, acting directly on the hair strands, forming a dynamic protective layer between the hair and the heat source, effectively isolating the high-temperature hot air, preventing the hot air from blowing directly onto the scalp and hair roots and causing burns, thus improving the safety and comfort of use.

[0010] Preferably, the ventilation comb includes a mounting frame, which is plugged into the cold air outlet. The side wall of the mounting frame is vertically arranged with a number of hollow comb teeth that are connected through it, and the side wall of the hollow comb teeth is horizontally opened with a number of ventilation holes.

[0011] Through the above technical solution, multiple ventilation holes are opened on the side wall of the hollow comb teeth, so that cool air can blow onto the hair strands from multiple angles and close distances from the side of the comb teeth. This not only enhances the anti-scalding and cooling effect, but also helps with styling. It allows the airflow to penetrate into the gaps between the hair strands, improving the hair's fluffiness and styling durability, making the blow-drying process gentler and faster.

[0012] Preferably, the opening and closing pressing assembly includes two symmetrically arranged L-shaped displacement plates and symmetrically opened sliding grooves on the front and rear inner walls of the storage shell. The outer side walls of the L-shaped displacement plates are slidably connected to the inner side walls of the sliding grooves. A spring is fixed between the two L-shaped displacement plates. An inner connecting tube is fixed to the top of each L-shaped displacement plate. The bottom of each L-shaped displacement plate is connected to the top of the adjacent bellows hose.

[0013] With the above technical solution, when combing and blowing long hair, a strand of hair to be blown is passed between the two rectangular shells, and then the pressing handles on both sides are pressed or moved at the same time, causing the L-shaped displacement plate to slide in the sliding groove, compressing or releasing the spring, thereby causing the two heat-proof direct blowing components to open or close to adapt to different hairstyles and combing needs.

[0014] Preferably, the airflow separation housing includes a housing body fixed to the bottom of a rectangular housing. An external connecting pipe is connected through the bottom of the housing body. An air baffle is fixed inside the cavity of the housing body. The bottom of the air baffle is located in the middle of the external connecting pipe. The top of the air baffle is located between the hot air inlet and the cold air inlet. The external connecting pipe is provided with a rotation locking mechanism that cooperates with the internal connecting pipe to rotate and lock the anti-heat air direct blowing component. The inner wall of the air baffle and the outer wall of the internal connecting pipe are rotated and sealed together.

[0015] Through the above technical solution, the air baffle ensures that the airflow from the bellows hose is pre-separated into two paths at the external connecting pipe, leading to the hot air chamber and the cold air chamber respectively, thus guaranteeing the reliability of air path isolation. The design of the internal connecting pipe and the rotary locking mechanism allows the anti-heat air direct blowing component to not only open and close relative to the handle, but also rotate around the connecting axis, realizing quick switching between the opening and closing combing mode and the direct blowing mode, enhancing the product's functional versatility and operational stability.

[0016] Preferably, the rotary locking mechanism includes locking holes symmetrically opened on the outer side wall of the inner connecting pipe and movable grooves opened circumferentially on the inner side wall of the outer connecting pipe. The locking holes and movable grooves are positioned correspondingly. Locking pins are slidably connected inside each movable groove. A spring is fixedly connected to one end of each locking pin located in the movable groove. A hemispherical shape is provided at the end of each locking pin located outside the groove.

[0017] With the above technical solution, when the user switches the device to direct blowing mode, the rotating hot air direct blowing component drives the external connecting pipe to rotate, and the hemispherical end of the locking post is pressed back into the movable groove, compressing the second spring. When it rotates to the locking position of the locking hole, the corresponding spring pushes the locking post into the locking hole, clearly indicating that the locking is in place, providing a good user experience and ensuring the accuracy and stability of angle adjustment.

[0018] Preferably, a motor is fixedly installed on the inner wall of the hollow handle, a fan blade is fixedly connected to the top output end of the motor, and several air inlets are opened along the circumference on the bottom outer wall of the hollow handle, with the air inlets located below the motor.

[0019] The beneficial effects of this invention are as follows: With the addition of a heat-resistant direct-blowing component, airflow enters the rectangular housing through the hot air inlet and cold air inlet, respectively, and flows into the hot air chamber and cold air chamber. The airflow entering the hot air chamber is heat-processed and flows out from the hot air outlet, while the low-temperature airflow entering the cold air chamber flows from the cold air outlet to the ventilation comb. The ventilation comb guides the cold air above the scalp, directly acting on the hair strands, forming a dynamic protective layer between the hair and the heat source. This effectively isolates the high-temperature hot air, preventing the hot air from blowing directly onto the scalp and hair roots and causing burns, thus improving safety and comfort during use.

[0020] With the opening and closing pressing components, when the heat-proof air blowing components on both sides are closed, the ventilation combs on both sides, together with the rectangular shell, clamp and comb the hair strands, breaking them into several small strands. Hot and cold air pass through the gaps between the two small strands of hair, improving the blowing efficiency while enhancing the uniformity and quality of the hair blowing. This allows the hair to be combed and dried at the same time, avoiding messy hair after drying.

[0021] (3) By setting a rotating locking mechanism, the synchronous rotation of the entire heat-proof direct blowing component ensures the heat-proof direct blowing component's anti-scalding function, while enabling a quick and stable switch between the opening and closing combing mode and the direct blowing mode. The combing mode is suitable for drying long hair that is far from the scalp, while the direct blowing mode is suitable for drying hair that is close to the scalp, thus enhancing the product's functionality and convenience.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] like Figures 1-9 As shown, this embodiment of a heat-resistant direct-blowing hair dryer includes a hollow handle 1. A storage shell 2 is fixedly connected to the top side wall of the hollow handle 1. An opening and closing pressing component 3 is provided inside the storage shell 2. Two accordion hoses 8 are connected through the top of the hollow handle 1. The top of the accordion hoses 8 are connected to the bottom of the opening and closing pressing component 3. A symmetrically arranged airflow separating shell 4 is rotatably installed above the opening and closing pressing component 3. A heat-resistant direct-blowing component 5 is connected through the top of each airflow separating shell 4. The heat-resistant direct-blowing components 5 on both sides are symmetrically arranged. The opening and closing pressing component 3 drives the heat-resistant direct-blowing components 5 on both sides to open and close, so as to comb the hair while performing heat-resistant blow-drying. The heat-resistant direct-blowing components 5 on both sides rotate forward synchronously to switch the blow-drying mode. A motor 6 is fixedly installed on the inner side wall of the hollow handle 1. A fan blade 7 is fixedly connected to the top output end of the motor 6. A plurality of air inlets 101 are opened along the circumference on the bottom outer side wall of the hollow handle 1. The air inlets 101 are located below the motor 6.

[0026] By incorporating symmetrical, openable, and rotatable heat-resistant direct-blowing components 5, the hair-drying and hair-combing functions are combined. Users can comb their hair while utilizing these components, positioned on both sides, avoiding the burning sensation and risk of burns caused by the concentrated airflow from traditional hair dryers that blow hot air directly onto the scalp and hair roots. This improves user comfort and safety. Furthermore, the synchronized rotation of the entire component allows for quick switching between open / close combing mode and direct-blowing mode, enhancing the product's functionality and convenience.

[0027] like Figure 6 , Figure 7 As shown, the heat-prevention direct-blowing assembly 5 includes a rectangular housing 501, a pressing handle 502, a ventilation comb 503, a heat insulation plate 504, an airflow distribution plate 505, and a thermoelectric wire mesh 506. The heat insulation plate 504 is vertically fixed inside the rectangular housing 501, dividing the inner cavity of the rectangular housing 501 into a hot air chamber 5013 and a cold air chamber 5014. A hot air inlet 5015 is opened at the bottom of the hot air chamber 5013, and a cold air inlet 5016 is opened at the bottom of the cold air chamber 5014. Several hot air outlets 5011 are opened through one side of the outer wall of the hot air chamber 5013, and a cold air outlet 5017 is opened through one side of the outer wall of the cold air chamber 5014. 17. Hot air outlet 5011 is located on the same side. Air vents 5012 are opened through both sides of the rectangular shell 501. The air vents 5012 correspond to the hot air outlet 5011 on the other side of the rectangular shell 501. Airflow distribution plate 505 and thermoelectric wire mesh 506 are vertically arranged and installed inside the hot air cavity 5013. Airflow distribution plate 505 is close to hot air outlet 5011. Airflow distribution plate 505 and thermoelectric wire mesh 506 are both located between hot air outlet 5011 and hot air inlet 5015. Press handle 502 is fixedly installed on the front side wall of the rectangular shell 501. Ventilation comb 503 is inserted and fixedly connected to the outer edge of the cold air outlet 5017.

[0028] During purging, the airflow enters the cavity of the rectangular housing 501 through the hot air inlet 5015 and the cold air inlet 5016, respectively entering the hot air cavity 5013 and the cold air cavity 5014. The airflow entering the hot air cavity 5013 first passes through the thermoelectric wire mesh 506 and then through the airflow distribution plate 505, making the airflow velocity and temperature distribution more uniform. Finally, the hot air flows out from the hot air outlet 5011. The unheated, low-temperature airflow entering the cold air cavity 5014 flows from the cold air outlet 5017 to the ventilation comb 503. The ventilation comb 503 guides the cold air above the scalp, acting directly on the hair strands, forming a dynamic protective layer between the hair and the heat source, effectively isolating the high-temperature hot air and preventing the hot air from blowing directly onto the scalp and hair roots, thus improving safety and comfort. The heat insulation plate 504 ensures that the hot and cold airflows do not interfere with each other within the cavity, achieving precise temperature control. The ventilation vent 5012 corresponds to the hot air outlet 5011 of the rectangular housing 501 on the other side, ensuring rapid airflow and preventing the concentrated impact of high-temperature hot air on the hair strands, thus further enhancing the protection of the hair strands.

[0029] like Figure 6 As shown, the ventilation comb 503 includes a mounting frame 5031, which is plugged into and connected to the cold air outlet 5017. The side wall of the mounting frame 5031 is vertically arranged with a number of hollow comb teeth 5032, and the side wall of the hollow comb teeth 5032 is horizontally opened with a number of ventilation holes 5033.

[0030] The hollow comb teeth 5032 have multiple ventilation holes 5033 on their side walls, allowing cool air to blow onto the hair from multiple angles and at close range from the sides of the comb teeth. This not only enhances the anti-scalding and cooling effect but also aids in styling. The airflow penetrates into the gaps between hair strands, improving hair volume and style longevity, making the drying process gentler and faster. The mounting frame 5031 and the cool air outlet 5017 are connected by a plug-in joint, facilitating disassembly and cleaning of the comb teeth, preventing hair tangling and dust accumulation, and simplifying maintenance.

[0031] like Figure 5 As shown, the opening and closing pressing assembly 3 includes two symmetrically arranged L-shaped displacement plates 302 and symmetrically opened sliding grooves 301 on the front and rear inner walls of the storage shell 2. The outer side walls of the L-shaped displacement plates 302 are slidably connected to the inner side walls of the sliding grooves 301. A spring 304 is fixed between the two L-shaped displacement plates 302. An inner connecting tube 303 is fixedly connected to the top of each L-shaped displacement plate 302. The bottom end of each L-shaped displacement plate 302 is connected through to the top of the adjacent bellows hose 8.

[0032] When combing and blow-drying long hair, a strand of hair to be blown is passed between the two rectangular housings 501. Then, the pressing handles 502 on both sides are pressed or moved simultaneously, causing the L-shaped displacement plate 302 to slide within the sliding groove 301, compressing or releasing the spring 304. This causes the two heat-resistant direct-blowing components 5 to open or close, adapting to different hairstyles and combing needs. When the heat-resistant direct-blowing components 5 close, the ventilation combs 503 on both sides, in conjunction with the rectangular housings 501, clamp and comb the hair strands, breaking them into several small strands. Hot and cold air pass through the gaps between these small strands, improving blow-drying efficiency while enhancing the uniformity and quality of the blow-drying. The accordion hose 8 is directly connected to the L-shaped displacement plate 302, ensuring continuous airflow during component movement and preventing air pressure loss.

[0033] like Figure 8 As shown, the airflow separation housing 4 includes a housing body 401 fixed to the bottom of a rectangular housing 501. An external connecting pipe 403 is connected through the bottom of the housing body 401. An air baffle 402 is fixed inside the cavity of the housing body 401. The bottom of the air baffle 402 is located in the middle of the external connecting pipe 403. The top of the air baffle 402 is located between the hot air inlet 5015 and the cold air inlet 5016. The external connecting pipe 403 is provided with a rotation locking mechanism 404 that cooperates with the internal connecting pipe 303 to rotate and lock the anti-heat air direct blowing assembly 5. The inner wall of the air baffle 402 and the outer wall of the internal connecting pipe 303 are rotated and sealed together.

[0034] The baffle plate 402 ensures that the airflow from the bellows hose 8 is pre-divided into two paths at the outer connecting pipe 403, leading to the hot air chamber 5013 and the cold air chamber 5014 respectively, guaranteeing the reliability of air path isolation. The inner connecting pipe 303 and the rotary locking mechanism 404 allow the anti-heat air direct blowing component 5 to not only open and close relative to the handle, but also rotate around the connecting axis, realizing quick switching between the opening and closing combing mode and the direct blowing mode. Users can adjust the air outlet angle as needed, while the rotary locking mechanism 404 provides clear positioning and feel at commonly used angles, enhancing the product's functional versatility and operational stability.

[0035] like Figure 5 , Figure 9 As shown, the rotary locking mechanism 404 includes locking holes 4041 symmetrically opened on the outer side wall of the inner connecting tube 303 and movable grooves 4042 opened circumferentially on the inner side wall of the outer connecting tube 403. The locking holes 4041 and movable grooves 4042 are positioned corresponding to each other. Locking pins 4044 are slidably connected inside the movable grooves 4042. A spring 4043 is fixedly connected to one end of the locking pins 4044 located in the movable grooves 4042. A hemispherical shape is provided at the end of the locking pins 4044 located outside the grooves.

[0036] When a more direct and faster drying is needed, the user can rotate the two heat-resistant direct-blowing components 5 to the angle where the hot air outlet 5011 faces the hair, switching to a direct-blowing mode closer to that of a traditional hair dryer. The heat-resistant direct-blowing components 5 drive the external connecting tube 403 to rotate, and the hemispherical end of the locking post 4044 is pressed back into the movable groove 4042, compressing the second spring 4043. When rotated to the locked position of the locking hole 4041, the corresponding spring 4043 pushes the locking post 4044 into the locking hole 4041, producing a clear "click" sound and tactile feedback, clearly indicating that the lock is in place, providing a good user experience, and ensuring the accuracy and stability of the angle adjustment.

[0037] The working principle of this embodiment is as follows: When the device is in combing and blowing mode, the user holds the hollow handle 1 and passes a strand of hair to be blown through the space between the two rectangular housings 501. Then, the user presses the pressing handles 502 on both sides at the same time, which drives the L-shaped displacement plate 302 to slide in the sliding groove 301, compressing the spring 304. This causes the two heat-proof direct blowing components 5 to retract. The ventilation combs 503 on both sides cooperate with the rectangular housings 501 and the user's combing action to clamp and comb the hair. At this time, the motor 6 is started to drive the fan blades 7 to rotate. The cold air enters the heat-proof direct blowing components 5 on both sides through the two bellows hoses 8 and the airflow separation housing 4 respectively.

[0038] Airflow enters the cavity of the rectangular housing 501 through the hot air inlet 5015 and the cold air inlet 5016, and then enters the hot air cavity 5013 and the cold air cavity 5014 respectively. The airflow entering the hot air cavity 5013 first passes through the thermoelectric wire mesh 506 and then through the airflow distribution plate 505. Finally, the hot air flows out evenly from the hot air outlet 5011. The low-temperature airflow entering the cold air cavity 5014 flows from the cold air outlet 5017 to the ventilation comb 503. Multiple ventilation holes 5033 are opened on the side wall of the hollow comb teeth 5032, so that the cold air can blow onto the hair strands from multiple angles and close distances from the side of the comb teeth, directly acting on the hair strands. A dynamic protective layer is formed between the hair and the heat source, effectively isolating the high-temperature hot air and preventing the hot air from blowing directly onto the scalp and hair roots to cause burns. It not only enhances the anti-scalding and cooling effect, but also helps with styling, allowing the airflow to penetrate into the gaps between the hair strands, improving the hair's fluffiness and the durability of the style.

[0039] When the user switches the device to direct blow mode, the two heat-resistant direct blow components 5 can be rotated so that the hot air outlet 5011 is directly facing the hair. During the rotation, the hemispherical end of the locking post 4044 is pressed back into the movable groove 4042, compressing the second spring 4043. When rotated to the locking position of the locking hole 4041, the corresponding spring 4043 pushes the locking post 4044 into the locking hole 4041, producing a clear "click" sound and tactile feedback, clearly indicating that the lock is in place. The user can then use the direct blow mode to blow on the scalp. Combined with the combing of the hollow comb teeth 5032 and the isolation of the high-temperature hot air, the hair is dried while combing, avoiding tangles and improving the efficiency of drying the hair. At the same time, the heat of the hot air is prevented from being directly transferred to the scalp, thus avoiding the risk of burns.
