Description

Technical Field

[0001] The utility model relates to the field of hair dryers, in particular to a quick-drying hair dryer. Background Art

[0002] As an indispensable personal care appliance in modern life, hair dryers' primary function is to quickly dry and style hair. To ensure proper operation and prevent foreign matter from entering the air duct, manufacturers often install filters at the air inlet of hair dryers. However, most of these filters are designed to be fixed to the blower's internal structure or directly connected to the outer casing. Over long-term use, foreign matter such as dust and hair can easily accumulate on the filters, causing blockage. Faced with this situation, users often have to resort to tedious disassembly or specialized tools for cleaning, which is not only time-consuming and labor-intensive, but also difficult to guarantee effective cleaning, causing considerable trouble for users. Utility Model Content

[0003] The present application provides a quick-drying hair dryer that has the effect of being able to disassemble and quickly clean the filter at the air inlet.

[0004] The quick-drying hair dryer provided in this application adopts the following technical solution:

[0005] A quick-drying hair dryer comprises a casing, the casing comprising a handheld part and a working part, a blowing chamber being formed in the working part, a blower and a heating wire being installed in the blowing chamber, and an air inlet and an air outlet being provided on both sides of the working part; a ring frame being fixedly installed at the air inlet, a mounting cylinder being fixed at the center of the ring frame, a magnet being installed in the mounting cylinder; and a filter screen being further provided, the filter screen being wrapped with a magnetic arc-shaped supporting mesh frame, and the arc-shaped supporting mesh frame being mounted at the air inlet by magnet adsorption.

[0006] Through the above technical solution, the filter is connected to the magnet at the air inlet through a magnetic arc-shaped support frame. The ring base can be manually removed to clean the filter, thereby reducing the workload required for cleaning the filter.

[0007] Preferably, it also includes an annular base, a plurality of L-shaped fixing blocks are fixed circumferentially on the arc-shaped support net frame, and the annular base has the same number of mounting seats as the L-shaped fixing blocks fixed circumferentially, and a plurality of the mounting seats are provided with mounting grooves that match the L-shaped fixing blocks.

[0008] Through the above technical solution, since the arc-shaped support mesh frame is not stable enough when directly connected to the air inlet, it is adopted to cooperate with the annular base to form a solid support system to ensure the stability of the structure; at the same time, the L-shaped fixing block cooperates with the mounting groove on the mounting seat, so that it can be easily installed on the annular base by simply rotating the arc-shaped support mesh frame, reducing the number of steps that affect the cleaning of the filter.

[0009] Preferably, the upper and lower ends of the joint between the annular base and the air inlet are provided with hand grooves.

[0010] Through the above technical solution, during the operation of disassembling or installing the annular base, the hand-friendly groove allows the user's fingers to better fit and apply force, thereby increasing the stability of the operation.

[0011] Preferably, the air inlet is provided with an annular groove on the outer side of the ring frame, and a convex ring that cooperates with the annular groove is fixed on the side of the annular base that cooperates with the air inlet; a number of positioning seats are provided in the annular groove, and magnets are also installed on a number of the positioning seats; a number of positioning grooves that cooperate with the magnets on the positioning seats are provided on the convex ring, and the positioning seats, the positioning grooves and the hand-friendly grooves are arranged corresponding to each other above and below.

[0012] Through the above technical solution, the cooperation between the ring groove and the convex ring as well as the positioning seat and the positioning groove limits the possibility of the ring base rotating at the air inlet. At the same time, by adding magnets, the stability is enhanced, reducing the situation where the parts of the hair dryer are scattered on the ground after accidentally falling to the ground.

[0013] Preferably, the heating wire is fixedly installed on multiple heating plates, and the multiple heating plates are connected and fixed to each other through one side surface to form an integral heating structure, and the angle between any two adjacent heating plates remains consistent; one end of the heating structure is connected to the fan, and the other end is connected to the air outlet.

[0014] Through the above technical solution, the heating plates are fixed into an integral structure to enhance the stability of the heating assembly and reduce the risk of loosening or damage due to vibration or long-term use; at the same time, since the heating wires are evenly distributed on multiple heating plates and the angle between any two adjacent heating plates is consistent, this helps to ensure that heat is evenly distributed throughout the heating structure, thereby improving heating efficiency and uniformity.

[0015] Preferably, a silencer is provided on the outside of the heating structure, one end of the silencer is connected to the fan, and the other end is connected to the air outlet. The silencer is designed to be tapered toward the air outlet, so that a cavity is formed between the silencer and the casing.

[0016] Through the above technical solution, the setting of the cavity prevents the transmission of noise, thereby reducing the noise of the hair dryer during use.

[0017] Preferably, the casing is constructed by splicing together two components, a front casing and a rear casing, and grooves are provided on both sides of the splicing portion of the front casing and the rear casing, and the two grooves are located in the working area of ​​the casing; PVC soft rubber pads are embedded in the grooves, and the PVC soft rubber pads are used to abut against the placement plane.

[0018] Through the above technical solution, the PVC soft rubber pad is used to increase the friction between the casing and the placement surface, thereby making the placement more stable and reducing the possibility of the hair dryer falling from the placement surface.

[0019] The technical effects of this utility model are mainly reflected in the following aspects:

[0020] 1. This utility model fixes the filter on a magnetic arc-shaped support frame, and connects the magnetic arc-shaped support frame to the magnet at the air inlet. The ring base can be manually removed to clean the filter, thereby reducing the workload required for disassembly and cleaning the filter;

[0021] 2. The utility model increases the firmness of the connection between the arc-shaped support frame and the air inlet by adding a ring base;

[0022] 3. The utility model provides a PVC soft rubber pad to increase the friction between the casing and the placement surface, thereby making the placement more stable and reducing the possibility of the hair dryer falling from the placement surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1-4 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0029] The present application discloses a quick-drying hair dryer:

[0030] Reference Figure 1-2 A quick-drying hair dryer includes a housing 1, which includes a handheld portion 11 and a working portion 12. The working portion 12 has a blowing chamber formed therein, in which a blower 13 and a heating wire 20 are installed. An air inlet 14 and an air outlet 15 are formed on either side of the working portion 12. A ring frame 2 is fixedly mounted at the air inlet 14, a mounting cylinder 21 is fixed at the center of the ring frame 2, and a magnet 3 is mounted within the mounting cylinder 21. The housing also includes a filter 4, which is wrapped with a magnetic curved support frame 5 and is fixed to the air inlet 14 by magnet 3. The filter 4 is attached to the magnet 3 at the air inlet 14 by the magnetic curved support frame 5. The ring base 6 can be manually removed to clean the filter 4, thereby reducing the workload required to disassemble and clean the filter 4. This prevents the accumulation of dust and hair on the filter 4 after long-term use, which may affect the working performance of the hair dryer 13.

[0031] Reference Figure 3 , further comprising an annular base 6. Several L-shaped fixing blocks 51 are circumferentially fixed to the arc-shaped support mesh frame 5. The same number of mounting seats 61 are circumferentially fixed to the annular base 6 as the L-shaped fixing blocks 51. Several mounting seats 61 are provided with mounting slots 62 that mate with the L-shaped fixing blocks 51. Because the arc-shaped support mesh frame 5 would not be stable if directly fastened to the air inlet 14, it is combined with the annular base 6 to form a solid support system, ensuring structural stability. Furthermore, the L-shaped fixing blocks 51 mate with the mounting slots 62 on the mounting seats 61, allowing the arc-shaped support mesh frame 5 to be easily installed on the annular base 6 simply by rotating it, reducing the number of steps that affect cleaning the filter screen 4.

[0032] Reference Figure 1-2 The upper and lower ends of the joint of the annular base 6 and the air inlet 14 are provided with advantageous hand grooves 7. During the operation of disassembling or installing the annular base 6, the advantageous hand grooves 7 allow the user's fingers to better fit and apply force, thereby increasing the stability of the operation.

[0033] Reference Figure 1-3The air inlet 14 is provided with an annular groove 141 on the outside of the ring frame 2. A protruding ring 63 is fixed to the side of the annular base 6 that contacts the air inlet 14 and cooperates with the annular groove 141. A plurality of positioning seats 142 are provided within the annular groove 141, and magnets 3 are also mounted on the positioning seats 142. The protruding ring 63 is provided with a plurality of positioning grooves 64 that cooperate with the magnets 3 on the positioning seats 142. The positioning seats 142 and the positioning grooves 64 are arranged in a vertically corresponding manner with the hand-friendly groove 7. The cooperation between the annular groove 141, the protruding ring 63, and the positioning seats 142 and the positioning grooves 64 limits the possibility of the annular base 6 rotating within the air inlet 14. At the same time, the addition of the magnets 3 enhances stability and reduces the possibility of the hair dryer 13 accidentally falling to the ground and its parts being scattered.

[0034] Reference Figure 4 , the heating wire 20 is fixedly mounted on a plurality of heating plates 8, and the plurality of heating plates 8 are interconnected and fixed through one side thereof to form an integral heating structure, and the angle between any two adjacent heating plates 8 remains consistent. At the same time, slots 81 are evenly opened on the other side of the heating plate 8 along the length direction of the heating plate 8 to facilitate the heating wire 20 to be fitted on the heating plate 8. One end of the heating structure is connected to the fan 13, and the other end is connected to the air outlet 15. Fixing the heating plates 8 into an integral structure enhances the stability of the heating assembly and reduces the risk of loosening or damage due to vibration or long-term use; at the same time, since the heating wire 20 is evenly distributed on the plurality of heating plates 8, and the angle between any two adjacent heating plates 8 remains consistent, this helps to ensure the uniform distribution of heat throughout the heating structure, thereby improving the heating efficiency and uniformity.

[0035] Reference Figure 4 A muffler 9 is sheathed around the outside of the heating structure. One end of the muffler 9 is connected to the fan 13, and the other end is connected to the air outlet 15. The end of the muffler 9 toward the air outlet 15 is designed to taper, creating a cavity between the muffler 9 and the housing 1. This cavity prevents the transmission of noise, thereby reducing the noise generated by the hair dryer 13 during use. Sound-absorbing foam can also be injected into the cavity to further reduce noise transmission.

[0036] Reference Figure 1 The housing 1 is constructed by joining a front housing 16 and a rear housing 17. Grooves 18 are defined on either side of the joint between the front and rear housings 16 and 17. Both grooves 18 are located in the working portion 12 of the housing 1. PVC soft rubber pads 10 are embedded within these grooves and are designed to abut against a placement surface. These pads increase friction between the housing 1 and the placement surface, ensuring a more stable placement and reducing the possibility of the hair dryer 13 falling off the placement surface.

[0037] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
