Description

Technical Field

[0001] The utility model relates to the field of hair dryers, in particular to a hair dryer with a cleaning structure. Background Technique

[0002] With the continuous improvement of people's living standards, the attention to personal image has increased day by day, and hair care and styling have become an important part of daily life. As a common hair styling tool, the hair dryer plays an indispensable role in people's lives. However, the integrated dust-proof grille on the hair dryer cannot be disassembled, so it is not convenient and fast to clean the dust-proof grille. At the same time, the single-layer dust-proof grille cannot effectively and comprehensively prevent dust, and a part of the dust will still enter the hair dryer and contact the heating element, generating a pungent smell.

[0003] The hair dryer with stepless speed regulation of the existing patent publication number CN221082977U includes a wind guide cylinder, a housing frame, a drive control structure and a handle. The front end of the drive control structure is fixedly connected with a wind guide cylinder, the rear end of the drive control structure is fixedly connected with a housing frame, and the lower end of the drive control structure is fixedly connected with a handle; the drive control structure includes a first limit mounting seat, a motor, a stepless speed regulator, a fan, a limit guide rod, a second limit mounting seat and a protective sleeve. The front part of the inner end of the protective sleeve is fixedly connected with a first limit mounting seat, the side end of the first limit mounting seat is limitedly mounted with a motor, the side end of the motor is connected with a stepless speed regulator, the side end of the stepless speed regulator is connected with a fan, the side end of the fan is sleeved with a limit guide rod, and the side end of the limit guide rod is fixedly connected with a second limit mounting seat.

[0004] Through the above settings, the existing technology can be connected with the drive control structure in a limited way by installing a wind guide cylinder to achieve the purpose of straight air guiding. At the same time, the rear end of the drive control structure is fixedly connected with a housing frame, which can be separated inside and outside to prevent objects from entering through the rear end of the drive control structure. Through the setting of the handle, it is convenient to control the operation of the drive control structure and convenient to hold for work. However, the hair dryer with stepless speed regulation of the existing technical solution has the following defects when operating:

[0005] (1) When the hair dryer is in use, fluff will be adsorbed on the surface of the housing frame. When a large amount of fluff adheres to the surface of the housing frame, if it is not cleaned in time, the ventilation rate will be reduced and the heat dissipation will be affected. Since the housing part is fixedly connected to the rear end of the protective sleeve of the hair dryer, the housing frame cannot be disassembled, and it is not convenient to operate when cleaning the fluff adhering to the surface of the housing frame.

[0006] (2) When the hair dryer is in use, dust can easily enter the hair dryer through the protective shell frame. When the hair dryer is working, it will generate a certain amount of heat. The accumulation of dust will block the heat dissipation channels, which may cause the temperature of the internal components to be too high and shorten their service life. A humid environment may promote the reproduction of bacteria. When dust accumulates inside the hair dryer, these bacteria may be spread to the hair and skin along with the hot air during use, posing a potential threat to health. Summary of the Invention

[0007] The present utility model aims to provide a hair dryer with a cleaning structure, mainly to solve the technical problem that in the prior art, fluff will adhere to the surface of the protective shell frame when the hair dryer is in use, and since the protective shell frame is not detachable, it is not convenient to clean. Secondly, it solves the technical problems that when the hair dryer is in use, dust will enter the hair dryer through the protective shell frame, the accumulation of dust will block the heat dissipation channels, and bacteria will be nourished.

[0008] To solve the above technical problems, the present utility model provides the following technical solutions:

[0009] A hair dryer with a cleaning structure includes a protective sleeve. The rear end of the protective sleeve is fixedly connected with a protective cover. The protective cover is hingedly connected with an annular plate. The inner wall of the annular plate is fixedly connected with a dust-proof net. The outer wall of the annular plate is fixedly connected with a fixed block. One side of the fixed block is fixedly connected with an arc-shaped block. A placement groove is opened on the inner wall of the protective cover. A clamping component for clamping the arc-shaped block is arranged in the placement groove. A first annular sliding groove is opened on the upper end surface of the annular plate. A second annular sliding groove is opened on the inner wall of the annular plate and is located below the dust-proof net. A ring-shaped accommodating groove is opened on the lower side wall of the second annular sliding groove. Round holes are symmetrically opened on the lower side wall of the ring-shaped accommodating groove. A filter cotton is clamped in the second annular sliding groove. A fixing component for fixing the filter cotton is arranged in the second annular sliding groove. Sliders are symmetrically and slidably connected in the first annular sliding groove. A scraping component for scraping the fluff attached to the surface of the dust-proof net is installed at the top of the slider.

[0010] Working principle and beneficial effects of the present utility model:

[0011] 1. Working principle: When it is necessary to clean the fluff attached to the surface of the dust-proof net, rotate the scraping component. After the scraping component scrapes the fluff attached to the surface of the dust-proof net clean, pull the annular plate. The annular plate will drive the fixed block to move. The movement of the fixed block will drive the arc-shaped block clamped in the clamping component to move out of the clamping component. Then pull the fixing component. At this time, the filter cotton attached with dust becomes loose. Pull out the filter cotton attached with dust from the second annular sliding groove. After replacing the clean filter cotton, push the fixing component. The fixing component fixes the periphery of the clean filter cotton in the second annular sliding groove. Press the annular plate. The annular plate drives the fixed block and the arc-shaped block to move in the opposite direction. After the arc-shaped block is clamped in the clamping component, the annular plate is fixed.

[0012] 2. Beneficial effects:

[0013] (1) In the prior art, by fixedly connecting a protective shell frame to the rear end of the protective sleeve of the hair dryer, the technical problem that fluff will be sucked into the hair dryer through the rear air inlet during the use of the hair dryer is solved. However, since the protective shell frame is fixedly connected to the rear end of the protective sleeve, it is not easy to clean when a large amount of fluff adheres to the surface of the protective shell frame. If the adhered fluff is not cleaned in time, the ventilation rate will be reduced and heat dissipation will be affected. In this solution, by setting an annular plate, a dust-proof net and a scraping component, the fluff adhering to the surface of the dust-proof net can be scraped off in time without disassembling the protective shell frame, solving the technical problem that during the use of the hair dryer, in the prior art, due to the strong air flow generated by the rotation of the internal fan at the air inlet, fluff is easily adsorbed on the surface of the protective shell frame, and the protective shell frame is not easy to remove and inconvenient to clean, and a large amount of fluff adsorbed on the surface of the protective shell frame will reduce the ventilation rate and affect heat dissipation.

[0014] (2) In this solution, by setting an annular plate, a filter cotton, a clamping component and a fixing component, the dust entering the hair dryer through the dust-proof net can be adsorbed, blocking the further entry of dust into the hair dryer interior and adhering to the internal parts of the hair dryer, solving the technical problems that dust accumulation in the hair dryer interior will block the heat dissipation channel and nourish bacteria.

[0015] Preferably, the clamping component includes connecting plates symmetrically and fixedly connected to the inner wall of the placement groove. A spring is fixedly connected to the opposite sides of the connecting plates. One end of the spring away from the connecting plate is fixedly connected to a clamping plate matching the arc-shaped block. When the filter cotton needs to be replaced, pull the annular plate. The annular plate will drive the fixing plate to move. The movement of the fixing plate will drive the arc-shaped block to move out of the clamping plate. After replacing the clean filter cotton, press the annular plate. The annular plate will drive the fixing block and the arc-shaped block to move in the opposite direction. When the arc-shaped block contacts the clamping plate during the movement, it will squeeze the clamping plate to move to both sides. The clamping plate moving to both sides will squeeze the spring until the arc-shaped block is clamped by the clamping plate, and at this time the annular plate is fixed.

[0016] Preferably, the fixing component includes a first annular magnet slidably connected to the inner wall of the annular accommodation groove. A connecting rod is fixedly connected to the lower end surface of the first annular magnet. One end of the connecting rod away from the first annular magnet passes through the round hole. A second annular magnet is embedded in the upper side wall of the second annular chute. The filter cotton is arranged between the first annular magnet and the second annular magnet. When the filter cotton needs to be replaced, pull the connecting rod. When the connecting rod drives the first annular magnet to move to abut against the inner wall of the annular accommodation groove, the filter cotton clamped in the second annular chute becomes loose. Pull out the filter cotton and snap the periphery of the clean filter cotton into the second annular chute. At this time, push the connecting rod. The connecting rod drives the first annular magnet to move. Since the filter cotton is located between the first annular magnet and the second annular magnet, the first annular magnet and the second annular magnet attract each other when approaching, fixing the filter cotton.

[0017] Preferably, a driving ring is fixedly connected to one end of the connecting rod away from the first annular magnetic attraction block; a driving ring is fixedly connected to one end of the connecting rod away from the first annular magnetic attraction block, which is more convenient when it is necessary to move the first annular magnet, and it is not necessary to only pull the connecting rod at a fixed position to move the first annular magnet.

Detailed implementation mode

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1-2 , Figures 4-8 shown, a hair dryer with a cleaning structure includes a protective sleeve 1. A protective cover 2 is fixedly connected to the rear end of the protective sleeve 1. The protective cover 2 is hingedly connected to an annular plate 3. A hand-pulling plate 6 is fixedly connected to one side of the annular plate 3. A dust-proof net 4 is fixedly connected to the inner wall of the annular plate 3. A fixed block 19 is fixedly connected to the outer wall of the annular plate 3. An arc-shaped block 18 is fixedly connected to one side of the fixed block 19. A placement groove 7 is opened on the inner wall of the protective cover 2. An inclined groove is opened at the relative position of the annular plate 3 and the placement groove 7 to prevent the inner wall of the protective cover 2 from colliding with the outer wall of the annular plate 3 and blocking the rotation and opening of the annular plate 3. A clamping component for clamping the arc-shaped block 18 is fixedly connected in the placement groove 7. The clamping component includes connecting plates 20 symmetrically and fixedly connected to the inner wall of the placement groove 7. A spring 22 is fixedly connected to the opposite sides of the connecting plates 20. One end of the spring 22 away from the connecting plates 20 is fixedly connected to a clamping plate 21 that matches the arc-shaped block 18, which can limit the annular plate 3 and prevent the annular plate 3 from rotating. A first annular sliding groove 15 is opened on the upper end surface of the annular plate 3. A second annular sliding groove 16 is opened on the inner wall of the annular plate 3 and is arranged below the dust-proof net 4. Round holes 17 are symmetrically opened on the lower side wall of the second annular sliding groove 16. A filter cotton 12 is clamped in the second annular sliding groove 16. The filter cotton 12 can adsorb dust and prevent dust from entering the hair dryer through the dust-proof net 4.

[0032] As Figures 2-6As shown, a fixing component for fixing the filter cotton 12 is arranged in the second annular sliding groove 16. The fixing component includes a first annular magnet 13 slidably connected to the inner wall of the annular accommodating groove 23. A connecting rod 11 is fixedly connected to the lower end surface of the first annular magnet 13. One end of the connecting rod 11 away from the first annular magnet 13 is fixedly connected to a driving ring 10. One end of the connecting rod 11 away from the first annular magnet 13 passes through the circular hole 17. A second annular magnet 14 is embedded in the upper side wall of the second annular sliding groove 16 to prevent the second annular magnet 14 from blocking the periphery of the filter cotton 12 from entering the second annular sliding groove 16. The filter cotton 12 is arranged between the first annular magnet 13 and the second annular magnet 14. When the first annular magnet 13 and the second annular magnet 14 approach each other and attract each other, the periphery of the filter cotton 12 can be fixed in the second annular sliding groove 16.

[0033] As Figures 1-2 , Figures 4-6 shown, sliding blocks 9 are symmetrically and slidably connected in the first annular sliding groove 15. The cross-sections of the first annular sliding groove 15 and the sliding blocks 9 are trapezoidal to prevent the sliding blocks 9 from sliding out of the first annular sliding groove 15. A scraping component for scraping the fluff attached to the surface of the dust-proof net 4 is installed at the top of the sliding block 9. The scraping component includes a long rod 5 fixedly connected to the upper ends of the symmetric sliding blocks 9. A brush strip 8 is fixedly connected to the side of the long rod 5 close to the dust-proof net 4. By simply rotating the long rod 5, the fluff attached to the surface of the dust-proof net 4 can be scraped off in time.

[0034] As can be seen from the above, the specific implementation manner of the present utility model is as follows:

[0035] When it is necessary to clean the surface of the dust-proof net 4, rotate the long rod 5. The rotation of the long rod 5 will drive the brush strip 8 to rotate on the surface of the dust-proof net 4. The rotation of the brush strip 8 will scrape off the fluff attached to the surface of the dust-proof net 4. After cleaning the dust-proof net 4, when it is necessary to replace the filter cotton 12, since the annular plate 3 is rotatably connected to the protective cover 2 through a hinge, pull the hand-pulling plate 6. The hand-pulling plate 6 drives the annular plate 3 to rotate around the hinge. The rotation of the annular plate 3 drives the fixed block 19 to move. The movement of the fixed block 19 drives the arc-shaped block 18 to move out of the clamping plate 21. At this time, the annular plate 3 rotates and opens. Pull the driving ring 10. The driving ring 10 drives the connecting rod 11 to move. The connecting rod 11 drives the first annular magnet 13 to move. At this time, the filter cotton 12 becomes loose. Take out the filter cotton 12 with attached dust from the second annular chute 16, and snap the periphery of the clean filter cotton 12 into the second annular chute 16. Push the driving ring 10. The driving ring 10 drives the connecting rod 11 to move in the reverse direction. The connecting rod 11 drives the first annular magnet 13 to move into the second annular chute 16. Since the filter cotton 12 is located between the first annular magnet 13 and the second annular magnet 14, when the first annular magnet 13 approaches the second annular magnet 14, they will attract each other and firmly clamp the filter cotton 12 in the middle to prevent the filter cotton 12 from slipping out of the second annular chute 16. After replacing the filter cotton 12, press the hand-pulling plate 6. The hand-pulling plate 6 drives the annular plate 3 to rotate in the reverse direction around the hinge. The rotation of the annular plate 3 drives the fixed block 19 and the arc-shaped block 18 to move in the reverse direction. When the arc-shaped block 18 contacts the clamping plate 21 during the movement, it will squeeze the clamping plate 21 to move to both sides. The movement of the clamping plate 21 will squeeze the spring 22 until the arc-shaped block 18 is completely snapped into the clamping plate 21. At this time, the annular plate 3 is fixed.

[0036] The above are only the embodiments of the present invention. Common general knowledge such as specific structures and characteristics in the solutions is not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
