Description

Technical Field

[0001] The present invention relates to hair dryer technology, and in particular provides a high-speed hair dryer structure. Background Art

[0002] A hair dryer (commonly known as an "electric hair dryer") is a commonly used household appliance. The design of an electric hair dryer is usually that the front of the heating device is a hot air outlet and the rear of the heating device is an air inlet. As hair dryers are made lighter and lighter and the number of revolutions is increased, the small, high-speed running appliance will inevitably produce louder noise and stronger suction, which will cause ear discomfort to the user. Suction that is too close to the air inlet will pose a safety hazard. At the same time, due to the compact structure of the breeze fan, the air inlet and even the heating device, the components that require hot air or heat dissipation cannot be optimally utilized. Summary of the Invention

[0006] In this example, it is preferred that a magnetic air nozzle is further included, and the magnetic air nozzle is adapted to the air outlet end.

[0007] In this example, it is preferred that the tube portion has an end surface and has an outer diameter smaller than that of the base portion, so that the base portion is formed with a stepped surface.

[0008] In this example, it is preferred that a control unit is also included; the main rod layer includes two matching shells with semicircular cross-sections, and the air duct is composed of the two shells that are matched in a snap-fitting form. An installation portion for the control unit is formed on the inner wall of one shell to place the control unit in the air duct.

[0009] In this example, it is preferred that the outer diameter of the plug section is smaller than the outer diameter of the main rod section and conforms to the diameter size of the adaptable lumen.

[0010] In this example, preferably, one of the two shells has a plug-in section with a hook, and the other shell has a plug-in section with a screw hole.

[0011] In this example, preferably, the main rod section has an end face, the end face of the main rod section is abutted by the end face of the tube portion and the hook is buckled on the other end face of the tube portion; the tube portion has a tube hole for screwing in and opposite to the screw hole.

[0012] In this example, preferably, the main rod section has a slot and a notch near the air inlet section, one end of the outer layer abuts the base step and covers the tube portion, and the other end of the outer layer extends an inner convex surface that is adapted to be snapped into the ventilation hood and includes a protrusion with an adapted slot on the inner wall.

[0013] In this example, it is preferred that the air inlet section includes two opposite side bars and wire tails connected to the two side bars, and an air inlet is formed between the wire tails and the main pole section, wherein the wire tails have wire holes adapted for the power supply wires, and countersunk notches are provided on the outer end faces of the wire tails corresponding to the two side bars, and screw holes are provided in the countersunk notches.

[0014] In this example, it is preferred that a reinforcing tube is further configured, which includes a strip tube configured on the outside of the two side strips, a tail ring connected to the two ends of the strip tube and surrounding the outer periphery of the line tail, and a connecting ring connected to and semi-surrounding the end of the main rod segment, the corresponding strip tube has a pin protruding on the other side of the connecting ring with an adapting notch, and the corresponding countersunk notch has an ear protruding on the inner ring of the tail ring with an adapting countersunk notch, and the ear has an ear hole for the screw hole in the corresponding countersunk notch to be adapted to the screw.

[0030] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other embodiments can be obtained based on these drawings without inventive work.

[0031] See Figures 1 to 4 The figure discloses a high-speed hair dryer structure, including a main body 10 and a handheld part 20. The main body includes a shell 11 and an air outlet end (not marked) formed by the shell for adapting a magnetic air nozzle 30. The end opposite to the air outlet end is closed by a rear cover 111, wherein:

[0032] The outer periphery of the housing 11 is formed with a connecting portion 12 adapted to fit the handle 20. The connecting portion includes a base portion (not labeled) connected to the outer periphery and a tubular portion 122 extending from the base. The outer diameter of the tubular portion end surface (or "cross section") 123 is indented (i.e., smaller than) that of the base, forming a stepped surface 121 at the base. A lumen 124 of the tubular portion extends through the base and communicates with the housing cavity 13 formed by the housing.

[0033] The handheld portion 20 includes a main rod layer 21, an outer layer 22 and a ventilation cover 23. The main rod layer 21 includes a shell 21a with a semicircular cross-section and another shell 21b that matches it. The shell 21a and the other shell 21b are buckled together to form an air duct F. The fixing structure for the buckled connection of the two shells 21a and 21b in this embodiment is a matching buckle 2114; the control unit (not shown) of this hair dryer is arranged in the air duct, and the operation of the fan drives natural wind into the air duct for circulation, so that the control unit arranged in the air duct can be effectively dissipated (cooled), thereby preventing the electronic components of the control unit from being affected by overheating and affecting their service life. Since the buckling, buckle and control unit structures are not the design points of the present invention, they will not be described in detail. In this embodiment, the main rod layer 21 includes a main rod section 211, a plug-in section 212 provided at one end of the main rod section and adapted to fit the connecting portion 12, and an air inlet section 213 provided at one end of the plug-in section 212, wherein: the outer layer 22 covers the main rod section and the plug-in section, and the ventilation hood is sleeved around the outer periphery of the air inlet section and connected to the main rod section. In this embodiment, the outer diameter of the plug-in section 212 is smaller than the outer diameter of the main rod section but meets the diameter of the adapted tube cavity 124. A hook 2121 is provided on one shell plug-in section, and a screw hole 2122 corresponding to the tube hole 1221 is provided on the other shell plug-in section. During assembly, the plug-in section is inserted into the tube cavity, the end face of the main rod section abuts against the end face of the tube portion, and the hook is buckled against the other end face of the tube portion, making it difficult for it to naturally fall out; at the same time, the screw is screwed into the screw hole to the tube hole, so that the main rod layer 21 and the main body 10 are firmly integrated. In this example, the main rod section near the air inlet section has slots (such as the vertical slot 2111 and the horizontal slots 2112 on both sides of the vertical slot) and a notch 2113; one end of the outer cladding 22 covers the tube portion and the end face abuts the base step surface 121, and the hand-held portion 20 and the main body 10 form a sealed body through the connecting portion 12. In this example, the other end of the outer cladding extends out an inner convex surface (not marked) that is adapted to be snapped into the ventilation hood 23, and includes a protrusion with an adapted notch on the inner wall (i.e., a straight bar 221 adapted to the vertical slot 2111 and a horizontal bar 222 adapted to the horizontal slot 2112). When the outer cladding 22 is adapted to the main rod layer 21, the protrusion interferes with the notch, so that the outer cladding 22 will not shake or fall off naturally on the main rod layer 21. In this example, the air inlet section 213 includes a wire tail 2131 connected to two opposite side bars (not marked), and an air inlet 221 (not marked) is formed between the wire tail and the main pole section 211, wherein: the wire tail 2131 has a wire hole 2132 adapted for the power supply line, and a countersunk notch 2133 is provided on the outer end face of the wire tail corresponding to the two side bars, and a screw hole 2134 is provided in the countersunk notch.In this embodiment, a frame-type reinforcing tube 24 is also provided, which includes a strip tube 241 arranged on the outside of the two side strips, a tail ring 242 connected to the two ends of the strip tube and surrounding the outer periphery of the line tail, and a connecting ring 243 connected to and semi-surrounding the end of the main rod section 211. The strip tube has a protruding pin 2431 on the other side of the connecting ring that matches the notch 2113, and an ear 2421 that matches the countersunk notch is protruding on the inner ring of the tail ring. The ear has an ear hole (not marked) for the screw to fit the screw hole in the countersunk notch. The screw is screwed into the screw hole to secure the reinforcing tube to the air inlet section 213. The wire tail is adapted with a washer 244, and a ventilated mesh portion 231 is provided around the ventilation cover 23. During assembly, the ventilation cover 23 is buckled onto the outer periphery of the reinforcing tube so that the buckle-in port (i.e., the large port) is buckled onto the outer periphery of the inner convex surface and rests against the step surface formed at the end. However, the wire end of the ventilation cover 23 is contracted to form a corresponding wire hole 2132 and a cover hole 232 for the power supply line configuration.

[0034] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0035] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
