Description

Technical Field

[0001] The utility model belongs to the technical field of hair dryers, and particularly relates to an anti-hair-absorption air inlet net structure and a hair dryer with the same. Background Art

[0002] Hair dryers are a common household appliance and are widely used in daily life. They consist of a heating wire and a small, high-speed fan, primarily used for drying and styling hair. When powered, the heating wire generates heat, and the air from the fan passes through the wire, becoming hot air. However, traditional hair dryers can absorb hair during use, which can be a serious health hazard.

[0003] The existing patent with announcement number CN219845426U discloses a body assembly and a hair dryer, including a shell, in which an air inlet, an air outlet and an air duct connecting the air inlet and the air outlet are provided; a first filter structure, a second filter structure and a third filter structure are provided in the shell, and the first filter structure, the second filter structure and the third filter structure are all cylindrically arranged; the first filter structure is provided at the air inlet, and the area between the first filter structure and the third filter structure is called the air inlet section; the second filter structure is movably installed in the air inlet section.

[0004] The hair dryer is provided with a three-layer filter structure, which can effectively filter the inhaled airflow. The first filter mechanism will filter the airflow at the air inlet to remove larger particulate impurities. The second filter mechanism will filter the airflow in the air inlet section to reduce the passage of fine impurities and broken hair. The third filter mechanism will filter the airflow passing through the second filter mechanism again to make the airflow in the air duct clean and pollution-free. However, long-term use will cause more and more impurities to accumulate in the second filter mechanism, thereby reducing the air intake in the air duct. However, if the second filter mechanism is to be cleaned, it is necessary to remove the second filter mechanism from the air inlet section and reinstall it after cleaning. Repeated disassembly and installation will wear out the parts and loosen the connections between the parts, thereby reducing the overall stability of the hair dryer. In addition, the process of disassembling and installing the second filter mechanism will waste a lot of the operator's time. Utility Model Content

This simultaneous rotation and sliding allows the push plate to more thoroughly clean the filter plate. The cleaning process is highly automated, saving time and effort. Furthermore, disassembly is unnecessary, improving the overall stability of the hair dryer.

[0016] The two-layer stainless steel mesh can effectively prevent hair absorption problems, and is easy to clean without damaging parts.

[0017] There is a certain gap between the two layers of steel mesh, which can reduce the probability of hair absorption without affecting the air intake efficiency of the hair dryer. It avoids the problem of low air volume caused by low air intake efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0026] like Figure 1-Figure 4As shown, the technical solution adopted by the present invention is as follows: an anti-hair suction air inlet net structure and a hair dryer having the same, comprising a main body 1, with a plurality of air inlet holes 2 formed on one side of the main body 1 and a plurality of air outlet holes 6 formed on the other side of the main body 1. A heating plate 7 is fixedly disposed vertically within the main body 1, and a handle 5 is mounted at the bottom of the main body 1.

[0027] A support frame 8 is fixedly mounted within the main body 1, and a motor 9 is fixedly mounted on one end of the support frame 8 near the air inlet 2. A rotating shaft 10 is fixedly mounted on the output end of the motor 9, and three circumferentially distributed fan blades 11 are fixedly mounted on the circumferential surface of the rotating shaft 10. The other end of the rotating shaft 10 is rotatably connected to the inner wall of the main body 1.

[0028] By starting the heating plate 7 and the motor 9, the output end of the motor 9 drives the rotating shaft 10 to rotate, and the rotation of the rotating shaft 10 drives the fan blades 11 to rotate. The rotation of the fan blades 11 generates suction, which draws the outside air through the air inlet 2. The air entering the main body 1 is heated by the heating plate 7 and then discharged from the air outlet 6.

[0029] Two filter plates 12 are movably provided on the circumferential surface of the rotating shaft 10, with a certain gap between the two filter plates 12. The circumferential surface of the filter plate 12 is fixedly connected to the inner wall of the main body 1, and the filter plate 12 is specifically a stainless steel mesh.

[0030] The air entering the main body 1 is filtered by the two layers of filter plates 12, which retain impurities and hair on the right side of the filter plate 12 closest to the air inlet 2. By setting the gap between the two filter plates 12, the probability of hair absorption by the anti-hair absorption air inlet net structure and the hair dryer having the same can be reduced.

[0031] The end gear 17 is movably provided on the circumferential surface of the rotating shaft 10 and fixedly connected to the facing surface of the rightmost filter plate 12. The fixing box 13 is fixedly provided on the circumferential surface of the rotating shaft 10 and rotatably connected to the facing surface of the rightmost filter plate 12.

[0032] The fixed box 13 has a cross-section shaped along the axis of the rotating shaft 10, and a screw 14 is rotatably mounted on the fixed box 13. A spur gear 18 is fixedly mounted on the end of the screw 14 near the rotating shaft 10. The spur gear 18 meshes with an end gear 17. The transmission ratio between the end gear 17 and the spur gear 18 is greater than 1, ensuring that the screw 14 rotates slowly and smoothly when the rotating shaft 10 rotates. The end of the screw 14 away from the rotating shaft 10 is slidably connected to the inner wall of the main body 1. The inner wall of the main body 1 defines a third annular groove 19, and the end of the screw 14 away from the rotating shaft 10 is slidably mounted in the third groove 19.

[0033] The circumferential surface of the screw rod 14 is provided with a reciprocating thread, and the reciprocating thread is threaded through a push plate 15. The reciprocating thread, the push plate 15 and the ball constitute a ball screw nut pair.

[0034] The rotation of the rotating shaft 10 drives the fixed box 13 to rotate, and the rotation of the fixed box 13 drives the screw rod 14 to rotate around the axis of the rotating shaft 10. Thereby driving the spur gear 18 to rotate around the axis of the rotating shaft 10.

[0035] Since the face gear 17 and the spur gear 18 are meshed, the spur gear 18 rotates around the axis of the rotating shaft 10 and also rotates itself, thereby driving the screw rod 14 to rotate around the axis of the screw rod 14. The rotation of the screw rod 14 around the axis of the screw rod 14 drives the push plate 15 to reciprocate along the axis of the screw rod 14.

[0036] The push plate 15 rotates around the axis of the rotating shaft 10 and also reciprocates along the axis of the screw rod 14 , thereby cleaning impurities from the right side of the filter plate 12 near the air inlet 2 .

[0037] A collecting component is provided at the bottom of the main body 1 .

[0038] The collection assembly includes a collection box 4. Two second grooves 16 are symmetrically defined on the outer surface of the main body 1. Both ends of the collection box 4 slide within the second grooves 16. The collection box 4 engages with the second grooves 16 in a limited manner. A connecting cavity 22 is defined in the main body 1, connecting the third groove 19 with the collection box 4.

[0039] The outer surface of the main body 1 defines a first groove 3, which communicates with the second groove 16. A slider 21 is slidably disposed within the first groove 3, with a spring 20 disposed between the slider 21 and the first groove 3. One end of the spring 20 is fixedly connected to the inner sidewall of the first groove 3, and the other end of the spring 20 is fixedly connected to the end of the slider 21 away from the second groove 16.

[0040] The slider 21 is used to limit the collection box 4. The slider 21 is limited and cooperates with the first groove 3 and the second groove 16 to prevent the collection box 4 from sliding when the hair or garbage in the collection box 4 is not being processed.

[0041] The cleaned impurities are discharged into the collection box 4 through the connecting cavity 22. When the collection box 4 needs to be cleaned, the slider 21 is pushed to move the slider 21 in the first groove 3 in a direction away from the second groove 16, and the spring 20 is in a compressed state.

[0042] When the collecting box 4 can slide along the second groove 16, stop pushing the slider 21 and remove the collecting box 4. After the collecting box 4 is removed, the spring 20 will push the slider 21 to reset under its own elastic effect.

[0043] How it works

[0044] When the heating plate 7 and motor 9 are turned on, the output of motor 9 drives the rotating shaft 10 to rotate, which in turn drives the fan blades 11 to rotate. The rotation of the fan blades 11 generates suction, which draws air from the outside into the main body 1 through the air inlet 2. The air entering the main body 1 is heated by the heating plate 7 and then discharged through the air outlet 6.

[0045] The air entering the main body 1 will be filtered by the two layers of filter plates 12 , and the filter plates 12 will retain impurities and hair on the right side of the filter plate 12 closest to the air inlet 2 .

[0046] At the same time, when the rotating shaft 10 rotates, the fixed box 13 is also driven to rotate, and the rotation of the fixed box 13 drives the screw rod 14 to rotate around the axis of the rotating shaft 10. Thereby driving the spur gear 18 to rotate around the axis of the rotating shaft 10.

[0047] Since the face gear 17 and the spur gear 18 are meshed, the spur gear 18 rotates around the axis of the rotating shaft 10 and also rotates itself, thereby driving the screw rod 14 to rotate around the axis of the screw rod 14. The rotation of the screw rod 14 around the axis of the screw rod 14 drives the push plate 15 to reciprocate along the axis of the screw rod 14.

[0048] The push plate 15 rotates around the axis of the rotating shaft 10 and also reciprocates along the axis of the screw rod 14 , thereby cleaning impurities from the right side of the filter plate 12 closest to the air inlet 2 .

[0049] The cleaned impurities are discharged into the collection box 4 through the connecting cavity 22. When the collection box 4 needs to be cleaned, the slider 21 is pushed to move the slider 21 in the first groove 3 in a direction away from the second groove 16, and the spring 20 is in a compressed state.

[0050] When the collecting box 4 can slide along the second groove 16, stop pushing the slider 21 and remove the collecting box 4. After the collecting box 4 is removed, the spring 20 will push the slider 21 to reset under its own elastic effect.
