Description

Technical Field

[0001] This invention relates to the field of hair combing device technology, specifically a hair combing and blow-drying device with a guide air duct. Background Technology

[0002] Combs and hair dryers are common household items. Combs are mainly used for combing hair, while hair dryers are mainly used for drying it. When using them, you usually need to hold the comb in one hand and the hair dryer in the other, simultaneously combing and drying your hair or beard. The two need to be used in conjunction, making the operation relatively cumbersome and inconvenient. Although there are now combs on the market that can be dried with a hairdryer, some problems still exist during use.

[0003] Chinese invention patent application CN109156968B discloses a comb capable of quickly drying hair and its usage method. The comb includes a handle, multiple rotating comb teeth rotatably connected to the handle, and multiple fixed comb teeth fixedly connected to the handle. The fixed comb handle has an air inlet chamber, and the rotating comb teeth have cavities communicating with the air inlet chamber. Each rotating comb tooth has a blower hole communicating with the cavity. Each rotating comb tooth is connected to a transmission mechanism for driving its rotation. The rotation of the comb teeth moves the hair, and the air continuously blown from the blower holes quickly dries the hair. The rotating comb teeth can reach the lower layers of hair, allowing them to be dried quickly as well.

[0004] While the above solution can simultaneously achieve the effects of blow-drying and combing with a comb that can be blown dry, it still has certain drawbacks in use. The air inlet tube is simply plugged into the connector at the end of the comb handle. Because the comb needs to be constantly shaken during use, the air inlet tube and connector can easily separate, affecting normal use. Furthermore, most existing combs have a fixed connection to the handle, which can lead to the air outlet or inner cavity of the comb becoming clogged with foreign objects after prolonged use, affecting usability. The fixed connection between the comb and handle also makes cleaning very inconvenient, which is detrimental to practical use. Summary of the Invention

[0005] The purpose of this invention is to provide a hair combing and blow-drying device with an airflow guide duct to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hair combing and blower device with a guide air duct, comprising a handle, a ventilation hole through the inner side of the handle, a slot at one end of the handle, a docking groove at the other end of the handle, a comb handle installed at the end of the handle with the slot, the comb handle being connected to the handle via a snap-fit ​​mechanism, and a locking mechanism for positioning the snap-fit ​​mechanism installed on the inner side of the handle; The comb handle has an air inlet chamber at one end near the handle, and multiple comb teeth are equidistantly arranged on the side of the comb handle.

[0010] As a further embodiment of the present invention, the locking mechanism includes a locking block slidably installed in the shrinkage groove. One end of the locking block extends into the locking groove, and the locking block at one end of the locking groove engages with the slot. An inclined surface is provided at the end of the locking block near the connecting groove. A circular groove is provided at the end of the locking block away from the slot. Sliding grooves are symmetrically provided on the inner sidewall of the circular groove. A sliding rod is slidably inserted into the circular groove.

[0011] As a further embodiment of the present invention, the air intake mechanism includes a connecting pipe inserted into the docking groove, a positioning ring fixedly connected to the outer side of the connecting pipe, the positioning ring engaging with the docking groove, an air intake hose fixedly connected to the end of the connecting pipe away from the handle, and a fan connector fixedly connected to the end of the air intake hose away from the connecting pipe.

[0012] As a further embodiment of the present invention, the handle is provided with a threaded hole at one end near the air intake mechanism, and a limiting groove is provided at the inner end of the threaded hole. Guide holes are symmetrically provided at the end of the handle. The adjustment mechanism includes an adjustment screw threaded into the threaded hole. A rotating shaft is fixedly connected to one end of the adjustment screw outside the threaded hole. A knob is fixedly connected to one end of the rotating shaft away from the adjustment screw. An abutment mechanism is sleeved on the outer side of the rotating shaft. The other end of the adjustment screw extends into the limiting groove. A concave frame is rotatably connected to one end of the adjustment screw in the limiting groove through a pin. The concave frame is slidably connected to the limiting groove. A U-shaped groove is provided at the end of the concave frame away from the adjusting screw. A round shaft is slidably connected in the U-shaped groove. One end of the round shaft extends to the inside of the concave frame and is fixedly sleeved with a transmission ring. The other end of the round shaft extends into the shrinkage groove, and the end of the round shaft in the shrinkage groove is fixedly connected to the connecting block.

[0013] As a further embodiment of the present invention, the abutting mechanism includes a transmission block rotatably mounted on the outside of the rotating shaft.

A guide rod is symmetrically fixedly connected to the side of the transmission block near the handle. The guide rod is slidably connected to the adjacent guide hole.

[0014] The beneficial effects of this invention are: 1. Connect the air intake mechanism to the handle. Use the adjustment mechanism to move the abutment mechanism closer to the handle, so that the U-shaped locking plate abuts against the outer side of the positioning ring, allowing the connecting pipe and the positioning ring to be firmly locked in the docking groove, thus firmly connecting the air intake mechanism and the handle. When the adjustment mechanism moves, it drives the locking mechanism to move synchronously, so that the locking block in the locking mechanism extends into the locking groove. Insert the round rod and scraper assembly into the air intake cavity, then connect the comb to the handle, so that the locking mechanism is connected to the handle. Then rotate the comb along the handle, so that the locking mechanism is engaged with the locking block, thus completing the locking of the locking block and firmly connecting the handle and the comb.

[0015] 2. The electric fan blows air into the ventilation holes through the air inlet mechanism. The air enters the air inlet chamber of the comb through the ventilation holes and the tube. The air rotates along the spiral plate, so that the air can enter the air outlet chamber and the second air outlet evenly. The air is blown out through the first air outlet on the side of the air outlet chamber. When combing hair, the air blown out through the first air outlet and the second air outlet can quickly dry the hair, greatly improving the efficiency and effect of drying.

[0016] 3. When it is necessary to disassemble the comb handle, first turn the knob in the opposite direction. This will cause the adjusting mechanism to move the abutting mechanism away from the handle, thus releasing the locking mechanism on the air intake mechanism. At this point, the air intake mechanism can be directly disassembled. The adjusting mechanism will then cause the locking mechanism to release the locking block. Rotate the comb handle in the opposite direction along the handle to separate it from the handle, completing the disassembly of the comb handle. Then, pull the round rod outward along the air intake cavity. The round rod will move the spiral plate and scraping component outward along the air intake cavity. The spiral plate and scraping component will work together to effectively clean the impurities in the air intake cavity. This completes the disassembly of all components, facilitating further cleaning of the comb handle. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1 to 10 The present invention provides a technical solution: a hair combing and blower device with a guide air duct, comprising a handle 1, characterized in that: a ventilation hole is provided through the inner side of the handle 1, a slot 11 is provided at one end of the handle 1, a docking groove 12 is provided at the other end of the handle 1, a comb 2 is installed at the end of the handle 1 with the slot 11, the comb 2 is connected to the handle 1 through a snap-fit ​​mechanism, and a locking mechanism for positioning the snap-fit ​​mechanism is installed on the inner side of the handle 1. The snap-fit ​​mechanism allows for easy installation and removal of the handle 1 and the comb handle 2. The locking mechanism locks the snap-fit ​​mechanism, thus fixing the snap-fit ​​mechanism and the handle 1 relative to each other, and thus fixing the handle 1 and the comb handle 2 relative to each other. The locking mechanism is also easy to adjust, making it convenient to remove the comb handle 2. The comb handle 2 has an air inlet chamber 21 at one end near the handle 1. Multiple comb teeth 22 are equidistantly arranged on the side of the comb handle 2. The comb handle 2 and the comb teeth 22 are integrally formed. An air outlet chamber 23 is opened at one end of the comb teeth 22 near the comb handle 2. The air outlet chamber 23 is connected to the air inlet chamber 21. Multiple first air outlet holes 24 are equidistantly opened on the side of the comb teeth 22. The first air outlet holes 24 are connected to the air outlet chamber 23. A second air outlet hole 25 is opened between two adjacent comb teeth 22 on the side of the comb handle 2. The second air outlet hole 25 is connected to the air inlet chamber 21. An insert tube 3 is fixedly connected to one end of the comb handle 2 near the handle 1. An air guide mechanism is installed in the inner cavity of the insert tube 3 and the air inlet chamber 21. The handle 1 has an air inlet mechanism installed at one end with a docking groove 12. The air inlet mechanism connects the handle 1 to the air outlet of the electric fan. The electric fan vents air into the ventilation hole through the air inlet mechanism. An adjustment mechanism is installed on the side of the handle 1 near the air inlet mechanism. The adjustment mechanism has a locking mechanism that locks the air inlet mechanism. The locking mechanism ensures that the air inlet mechanism is firmly installed on the handle 1.

[0021] Please see Figures 2 to 4 The insertion tube 3 is inserted into the slot 11. The air guiding mechanism includes a round rod 32 that is inserted through the inner cavity of the insertion tube 3. The round rod 32 extends into the air inlet cavity 21. One end of the round rod 32 contacts the innermost end of the air inlet cavity 21. One end of the insertion tube 3 is provided with a groove 31. The end of the round rod 32 inside the insertion tube 3 is symmetrically and fixedly connected with a limiting plate 33. The limiting plate 33 is engaged with the adjacent groove 31. When the insertion tube 3 is inserted into the slot 11, one side of the limiting plate 33 abuts against the innermost end of the slot 11. The limiting plate 33 is locked by the cooperation of the insertion tube 3 and the slot 11. A spiral plate 34 is fixedly connected to the outer side of the round rod 32. The spiral plate 34 extends into the air inlet cavity 21. A scraping component is fixedly connected to one end of the round rod 32 inside the air inlet cavity 21.

[0022] During installation, first insert the round rod 32 and the scraping component into the air inlet cavity 21, so that the limiting plate 33 is inserted into the groove 31 at the end of the insert tube 3; connect the comb 2 with the handle 1, and at the same time insert the insert tube 3 into the slot 11, so that the insert tube 3 firmly restricts the limiting plate 33 in the slot 11, thereby allowing the spiral plate 34 to be stably placed in the air inlet cavity 21. When blow-drying, the air enters the air inlet chamber 21 through the ventilation hole and the insert 3. The air flows in a spiral along the spiral plate 34 of the air inlet chamber 21, so that the air can enter the air outlet chamber 23 and the second air outlet 25 evenly. Finally, the air is blown out through the first air outlet 24 on the side of the comb teeth 22 and the second air outlet 25 on the side of the comb handle 2. While combing the hair, the first air outlet 24 and the second air outlet 25 work together to quickly dry the hair, greatly improving the efficiency and effect of blow-drying.

[0023] Please see Figure 3The scraping assembly includes an annular seat 35 fixedly sleeved on one end of the round rod 32. The annular seat 35 is disposed in the air inlet cavity 21. The outer side of the annular seat 35 slides in contact with the inner wall of the air inlet cavity 21. An annular cavity 36 is provided on the side of the annular seat 35 near the spiral plate 34. The edge of the inner side wall of the annular cavity 36 is set as a tapered slope.

[0024] When the round rod 32 is pulled outward along the air inlet cavity 21, the round rod 32 drives the spiral plate 34 and the annular seat 35 to slide outward along the air inlet cavity 21. The spiral plate 34 and the annular seat 35 work together to scrape away dust and other debris on the inner wall of the air inlet cavity 21. The scraped debris is collected by the annular cavity 36 until the annular seat 35 is pulled out from the air inlet cavity 21 and the insertion tube 3, thereby cleaning the air inlet cavity 21.

[0025] Please see Figure 2 , Figure 4 , Figure 6 and Figure 9 The handle 1 has an annular groove 13 at one end near the comb handle 2. The handle 1 has multiple connecting grooves 14 arranged in a ring array at one end near the comb handle 2. Each connecting groove 14 has a locking groove 15 at its bottom. The connecting grooves 14 and the locking grooves 15 are connected to the annular groove 13, and the connecting grooves 14 and the locking grooves 15 form an L-shaped arc groove. The handle 1 has a shrinkage groove 16 inside one end near the comb handle 2, and the locking mechanism is installed in the shrinkage groove 16. An annular pressure plate 26 is fixedly connected to the outer side of the comb handle 2 near the handle 1. The annular pressure plate 26 is integrally formed with the comb handle 2. The annular pressure plate 26 is in close contact with the handle 1, and a sealing gasket is provided between the annular pressure plate 26 and the handle 1. The locking mechanism includes an annular outer tube 4 fixedly connected to the side of the annular pressure plate 26 near the handle 1. Multiple locking blocks 41 are fixedly connected to the outer side of the annular outer tube 4 in an annular array. The number of locking blocks 41 is the same as the number of connecting grooves 14 and locking grooves 15. A locking groove 42 is opened on the side of the locking block 41 away from the annular pressure plate 26. The annular outer tube 4 is inserted into the annular groove 13, and the locking block 41 is locked into the locking groove 15.

[0026] When the comb handle 2 is connected to the handle 1, the insert tube 3 is connected to the slot 11, so that the annular outer tube 4 is inserted into the annular groove 13, and at the same time, the locking block 41 is inserted into the adjacent connecting groove 14. When the annular outer tube 4 is fully inserted into the annular groove 13, the locking block 41 slides into the locking groove 15 along the connecting groove 14. Then, the comb handle 2 is rotated along the handle 1. The comb handle 2 drives the locking block 41 to rotate through the annular outer tube 4, so that the locking block 41 rotates along the locking groove 15, so that the locking block 41 is misaligned with the connecting groove 14. At this time, the locking block 41 is at the end of the locking groove 15 away from the connecting groove 14, thus completing the locking of the locking block 41 and completing the initial installation of the comb handle 2.

[0027] When it is necessary to disassemble the comb handle 2, rotate the comb handle 2 in the opposite direction along the handle 1. The comb handle 2 drives the locking block 41 to rotate in the opposite direction through the annular outer tube 4, so that the locking block 41 rotates in the opposite direction along the locking groove 15, and the locking block 41 rotates until it is aligned with the connecting groove 14. At this time, pull the comb handle 2 away from the handle 1. The comb handle 2 drives the annular outer tube 4 to move outward along the annular groove 13. At the same time, the annular outer tube 4 drives the locking block 41 to slide through the locking groove 15 into the connecting groove 14 until the annular outer tube 4 is completely separated from the annular groove 13, so that the locking block 41 is separated from the handle 1. At the same time, the insertion tube 3 is removed from the slot 11, completing the disassembly of the comb handle 2.

[0028] Please see Figure 2 , Figure 4 and Figure 9 The locking mechanism includes a locking block 5 slidably installed in the shrinkage groove 16. One end of the locking block 5 extends into the locking groove 15, and the end of the locking block 5 in the locking groove 15 is engaged with the slot 42. The locking block 5 is slidably connected to the handle 1. The end of the locking block 5 near the connecting groove 14 has an inclined surface, and the end of the locking block 5 with the inclined surface is engaged with the slot 42. When the slot 41 rotates into the locking groove 15, the slot 41 first presses against the inclined surface, and the slot 41 pushes the locking block 5 into the shrinkage groove 16, causing the end of the locking block 5 to move out of the locking groove 15, thus locking the lock. A circular groove 51 is provided at the end of block 5 away from the locking block 41. A sliding groove 52 is symmetrically provided on the inner side wall of the circular groove 51. A sliding rod 53 is slidably inserted into the circular groove 51. A slider 54 is symmetrically fixedly connected to one end of the sliding rod 53 in the circular groove 51. The slider 54 is slidably connected to the adjacent sliding groove 52. A connecting block 6 is fixedly connected to the end of the sliding rod 53 away from the circular groove 51. The connecting block 6 is slidably connected to the shrink groove 16. A locking spring 55 is sleeved on the outside of the sliding rod 53. The two ends of the locking spring 55 abut against the locking block 5 and the connecting block 6 respectively. The locking spring 55 applies elastic force to the locking block 5.

[0029] When the comb handle 2 is connected to the handle 1, the locking mechanism is engaged in the handle 1. At this time, the handle 2 is rotated so that the locking block 41 is screwed into the locking groove 15. The locking block 5 is pressed by the locking block 41, causing the locking block 5 to slide into the shrinking groove 16. At the same time, the locking block 5 presses the locking spring 55. The sliding groove 52 on the locking block 5 slides along the slider 54, and the circular groove 51 slides along the slide rod 53. When the locking block 41 rotates to the end of the locking groove 15 that is away from the connecting groove 14, the locking groove 42 on the side of the locking block 41 is aligned with the locking block 5. Under the action of the locking spring 55, the locking block 5 engages with the locking groove 42, thereby completing the locking of the locking block 41.

[0030] When the locking block 41 is locked, the slider 54 is at the end of the slide groove 52 away from the locking block 41; When it is necessary to unlock the card block 41, pull the connecting block 6. The connecting block 6 drives the slider 54 to move through the slide rod 53. The slider 54 drives the locking block 5 to move synchronously, so that the locking block 5 slides into the shrink groove 16. At the same time, the locking block 6 separates from the card groove 42 on the side of the card block 41, thereby releasing the locking mechanism from locking the card block 41.

[0031] Please see Figure 1 , Figure 2 , Figure 5 and Figure 10 The air intake mechanism includes a connecting pipe 8 inserted into the docking groove 12. A positioning ring 81 is fixedly connected to the outer side of the connecting pipe 8. The positioning ring 81 is engaged with the docking groove 12. An air intake hose 82 is fixedly connected to the end of the connecting pipe 8 away from the handle 1. A fan connector 83 is fixedly connected to the end of the air intake hose 82 away from the connecting pipe 8. The fan connector 83 can be set as a magnetic connector to facilitate connection with some existing electric fans with magnetic heads. The air intake hose 82 is connected to the connecting pipe 8 and the fan connector 83 respectively. A sealing gasket is provided on the side of the positioning ring 81 so that the connecting pipe 8, the positioning ring 81 and the handle 1 can be sealed together.

[0032] The connecting pipe 8 and the insert pipe 3 are connected to both ends of the ventilation hole. Air is blown into the fan connector 83 through the air outlet of the electric fan. The air enters the connecting pipe 8 along the air inlet hose 82, blows into the ventilation hole along the connecting pipe 8, and then enters the comb 2 along the ventilation hole and the insert pipe 3.

[0033] Please see Figure 2 , Figure 5 and Figure 10 The handle 1 has a threaded hole 17 at one end near the air intake mechanism. A limit groove 18 is provided at the inner end of the threaded hole 17. Guide holes 19 are symmetrically provided at the end of the handle 1. The adjustment mechanism includes an adjustment screw 7 threaded in the threaded hole 17. A rotating shaft is fixedly connected to one end of the adjustment screw 7 outside the threaded hole 17. A knob 71 is fixedly connected to one end of the rotating shaft away from the adjustment screw 7. An abutment mechanism is sleeved on the outside of the rotating shaft. The other end of the adjustment screw 7 extends into the limit groove 18. A concave frame 72 is rotatably connected to one end of the adjustment screw 7 in the limit groove 18 through a pin. The movement of the adjustment screw 7 is fixedly connected to the pin. The pin is rotatably connected to the concave frame 72. The concave frame 72 is slidably connected to the limit groove 18. A U-shaped groove 73 is provided at the end of the concave frame 72 away from the adjusting screw 7. A round shaft 61 is slidably connected in the U-shaped groove 73. One end of the round shaft 61 extends to the inside of the concave frame 72 and is fixedly sleeved with a transmission ring 62. The other end of the round shaft 61 extends into the shrinkage groove 16, and the end of the round shaft 61 in the shrinkage groove 16 is fixedly connected to the connecting block 6. The round shaft 61 is slidably connected to the handle 1. The diameter of the transmission ring 62 is larger than the width of the U-shaped groove 73, so that the transmission ring 62 cannot pass through the U-shaped groove 73.

[0034] When it is necessary to connect the handle 1 to the comb handle 2, first insert the connecting tube 8 into the connecting slot 12, turn the knob 71, and the rotation of 71 drives the adjusting screw 7 to screw into the threaded hole 17 through the rotating shaft. The adjusting screw 7 drives the concave frame 72 to slide along the limiting groove 18, and the U-shaped groove 73 on the concave frame 72 slides along the round shaft 61 until the inner wall of the concave frame 72 contacts the transmission ring 62. At this time, the adjusting screw 7 continues to screw into the threaded hole 17, so that the concave frame 72 continues to move closer to the slot 1 than the limiting groove 18. One end of 1 slides, the concave frame 72 pushes the transmission ring 62 to move, the transmission ring 62 drives the round shaft 61 to move closer to the slot 11, the round shaft 61 drives the connecting block 6 to slide along the shrinkage groove 16, the connecting block 6 pushes the locking block 5 to move through the slide rod 53 and the locking spring 55, so that the end of the locking block 5 with the inclined surface extends into the locking groove 15; the concave frame 72 sets up to abut against the round shaft 61 and the transmission ring 62, so that the round shaft 61 cannot slide back, and at the same time the connecting block 6 cannot slide back.

[0035] When it is necessary to release the locking mechanism from locking the block 41, rotate the knob 71 in the opposite direction to make the adjusting screw 7 rotate outward along the threaded hole 17. The adjusting screw 7 drives the concave frame 72 to slide along the limiting groove 18, so that the concave frame 72 slides towards the end of the limiting groove 18 close to the mating groove 12. At this time, the U-shaped groove 73 of the concave frame 72 first slides along the round shaft 61. When the inner side wall of the concave frame 72 with the U-shaped groove 73 contacts the transmission ring 62, the adjusting screw 7 continues to drive the concave frame 72 to move. The concave frame 72 drives the transmission ring 62 to move. The transmission ring 62 drives the connecting block 6 to move synchronously through the round shaft 61. The connecting block 6 drives the locking block 5 to move via the slide bar 53 and the slider 54, causing the locking block 5 to separate from the locking block 41, thereby releasing the locking mechanism from locking the locking block 41.

[0036] Please see Figure 1 , Figure 2 , Figure 5 and Figure 10 The abutment mechanism includes a transmission block 9 rotatably mounted on the outside of the rotating shaft. The rotating shaft is rotatably connected to the transmission block 9 through a bearing. A U-shaped clamping plate 91 is fixedly connected to the side of the transmission block 9. The U-shaped clamping plate 91 is clamped on the outer side of the connecting pipe 8, and the U-shaped clamping plate 91 abuts against the positioning ring 81. A guide rod 92 is symmetrically fixedly connected to the side of the transmission block 9 near the handle 1. The guide rod 92 is slidably connected to the adjacent guide hole 19.

[0037] Initially, most of the adjusting screw 7 is screwed out of the threaded hole 17. At this time, the abutment mechanism is away from the handle 1, and the abutment mechanism will not hinder the docking and disassembly between the connecting tube 8 and the handle 1. When connecting the connecting pipe 8 to the handle 1, first insert the connecting pipe 8 and the positioning ring 81 into the docking groove 12, then turn the knob 71. The knob 71 drives the adjusting screw 7 to screw into the threaded hole 17 through the rotating shaft. The rotating shaft drives the transmission block 9 to move closer to the handle 1. The transmission block 9 drives the guide rod 92 to slide, so that the transmission block 9 can move stably. The transmission block 9 drives the U-shaped clamping plate 91 to clamp on the outside of the connecting pipe 8. When the adjusting screw 7 is fully screwed into the threaded hole 17, the U-shaped clamping plate 91 abuts against the outside of the positioning ring 81, so that the connecting pipe 8 and the positioning ring 81 can be firmly clamped in the docking groove 12, so that the air intake mechanism and the handle 1 are firmly connected. During disassembly, rotate knob 71 in the opposite direction to unscrew adjusting screw 7 from threaded hole 17, so that U-shaped clamp 91 is away from connecting pipe 8 and positioning ring 81, thereby facilitating disassembly of air intake mechanism.

[0038] Working principle: When in use, first connect the air intake mechanism to the handle 1, and insert the connecting pipe 8 and the positioning ring 81 into the docking groove 12. By rotating the knob 71, the adjustment mechanism moves into the handle 1. At the same time, the adjustment mechanism drives the abutment mechanism to move closer to the handle 1, so that the U-shaped plate 91 abuts against the outer side of the positioning ring 81, so that the connecting pipe 8 and the positioning ring 81 can be firmly locked in the docking groove 12, thereby making the air intake mechanism and the handle 1 firmly connected. When the adjusting mechanism moves, it drives the locking mechanism to move synchronously, so that the locking block 5 in the locking mechanism extends into the locking groove 15; Insert the round rod 32 and the scraping assembly into the air inlet cavity 21, so that the limiting plate 33 is inserted into the groove 31 at the end of the insert tube 3; when connecting the comb 2 and the handle 1, first insert the insert tube 3 into the slot 11, so that the locking mechanism is connected to the handle 1. When the locking mechanism is fully inserted into the handle 1, the annular pressure plate 26 contacts the end of the handle 1. Then rotate the comb 2 along the handle 1, so that the locking block 41 rotates to the side of the locking groove 15 away from the connecting groove 14. The locking block 41 pushes the locking block 5 to slide into the shrink groove 16. When the locking block 41 and the locking block 5 are aligned, the locking block 5 is engaged with the slot 42 under the action of the locking spring 55, thereby completing the locking of the locking block 41 and making the handle 1 and the comb 2 firmly connected.

[0039] The electric fan blows air into the ventilation hole through the air inlet mechanism. The air enters the air inlet chamber 21 of the comb handle 2 along the ventilation hole and the insertion tube 3. The air rotates spirally along the spiral plate 34, so that the air can enter the air outlet chamber 23 and the second air outlet 25 evenly. The air is blown out along the first air outlet 24 on the side of the air outlet chamber 23. When combing hair, the air blown out through the first air outlet 24 and the second air outlet 25 can quickly dry the hair, greatly improving the efficiency and effect of drying.

[0040] When it is necessary to disassemble the comb handle 2, first turn the knob 71 in the opposite direction. The adjustment mechanism will drive the abutment mechanism away from the handle 1, so that the abutment mechanism will release the lock on the air intake mechanism. At this time, the air intake mechanism can be directly disassembled. When the adjustment mechanism moves, it will drive the locking mechanism away from the locking block 41, so that the locking block 5 in the locking mechanism will separate from the slot 42, and the locking mechanism will release the lock on the locking block 41. Rotate the comb handle 2 in the opposite direction along the handle 1. The comb handle 2 drives the locking mechanism to rotate in the opposite direction, so that the locking block 41 is aligned with the connecting groove 14, thereby separating the locking mechanism from the handle 1. This allows the comb handle 2 to be separated from the handle 1, completing the disassembly of the comb handle 2 and facilitating cleaning or washing of the comb handle 2. At this point, the round rod 32 is pulled outward along the air inlet cavity 21. The round rod 32 drives the spiral plate 34 and the scraping component to move outward along the air inlet cavity 21. The spiral plate 34 and the scraping component work together to effectively clean the impurities in the air inlet cavity 21. At this point, the disassembly of each component is completed, which facilitates further cleaning of the comb handle 2.
