[0050] Embodiment 1

[0051] Reference Figures 1 to 9 , a multifunctional handheld hair dryer, comprising:

[0052] A handheld housing 1 having an air inlet 101 and an air outlet 102;

[0053] The fan inner shell 2 is arranged in the handheld shell 1, and an installation chamber 201 is formed between the fan inner shell 2 and the mobile phone shell, and the fan inner shell 2 forms an internal air duct 202, and the air inlet 101 is connected to the air outlet 102 through the internal air duct 202;

[0054] A high-speed motor 3 is disposed in the internal air duct 202 and is drivingly connected to the rotating fan blades 5;

[0055] A heating component 4 is disposed in the internal air duct 202, and the heating component 4 is located between the high-speed motor 3 and the air outlet 102;

[0056] The electric control component 6 is arranged in the installation chamber 201. The handheld housing 1 is provided with a control switch 601, and the control switch 601 forms a control connection with the electric control component 6;

[0057] A plurality of air outlet accessories 7, any one of which can be detachably connected to the handheld housing 1 and communicated with the air outlet 102. Preferably, the detachable connection is achieved through a screw-on structure 73 or a magnetic structure.

[0058] The above content is the basic structural scheme of the utility model. When in use, the electric control component 6 is controlled by the control switch 601, and the high-speed motor 3 is turned on to drive the rotating fan blades 5, thereby guiding the air, so that the external air enters the internal air duct 202 from the air inlet 101, and is discharged from the air outlet 102 after being pressurized. During use, the user can assemble any air outlet accessory 7 at the air outlet 102 for use, or remove the air outlet accessory 7 and use it directly.

[0059] In the utility model, a double shell structure consisting of a handheld outer shell 1 and a fan inner shell 2 is adopted. First, an installation chamber 201 is formed to provide an installation space for the electronic control component 6, and the installation chamber 201 is separated from the internal air duct 202 to reduce heat transfer, thereby enabling the electronic control component 6 to operate and be used in a relatively low temperature environment; second, the double shell structure can effectively reduce the temperature of the handheld outer shell 1, thereby avoiding scalding the user; third, the internal air duct 202 has fewer parts and a reasonable arrangement, which can greatly reduce the generation of turbulence and turbulence, thereby achieving a better flow guidance effect and reducing air volume loss; fourth, different from the existing hair dryer structure, the shell structure is compact and small in size, which is convenient for handheld use and storage.

[0060] The specific forms of the air outlet attachment 7 in the utility model are various, and two preferred embodiments are provided here, as follows:

[0061] 1. Reference Figure 5 The air outlet accessory 7 is a diffuser cover 71 , a front end of which is provided with an air outlet column 712 , and a front end of the diffuser cover 71 and the air outlet column 712 are both provided with a plurality of first air outlet holes 711 , and the first air outlet holes 711 are connected to the air outlet 102 .

[0062] The use of the diffuser cover 71 can indirectly expand the air outlet area. The diffuser cover 71 can also limit the air outlet to a specific area to prevent the air volume from escaping. In addition, the setting of multiple first air outlet holes 711 can provide an all-round and balanced flow diversion effect, so that the area covered by the diffuser cover 71 can all be winded. Furthermore, the setting of the air outlet column 712 can play a role of physical separation, that is, it can separate the diffuser cover 71 from the user's skin, thereby preventing the user from being hurt by being too close.

[0063] 2. Reference Figure 6 The air outlet accessory 7 is a comb tooth cover 72, and two rows of comb teeth 722 are protruding from the front end of the comb tooth cover 72, and a second air outlet hole 721 is provided between the two rows of comb teeth 722, and the second air outlet hole 721 is connected to the air outlet 102. The arrangement of multiple second air outlet holes 721 can provide an all-round and balanced flow diversion effect, so that the area covered by the comb tooth cover 72 can be exhausted; the arrangement of the comb teeth 722 can play the role of combing hair and other objects during use, thereby achieving the dual effects of blowing and combing at the same time.

[0064] The preferred setting of the internal air duct 202 is that the internal air duct 202 is in a straight cylindrical shape, and the air inlet 101, the internal air duct 202 and the air outlet 102 are distributed along the same straight line, thereby minimizing the loss of wind speed and air volume and reducing the power consumption of the whole machine.

[0065] Embodiment 2

[0066] Based on the structure of the first embodiment, this embodiment provides a preferred internal structure solution, specifically: Figure 3 , Figure 7 to Figure 9 The fan inner shell 2 includes a motor bracket 21, and the high-speed motor 3 is mounted on the motor bracket 21 so that the motor is stably mounted, and a plurality of guide blades 211 are arranged around the motor bracket 21. The guide blades 211 can firstly partition the internal air duct 202; secondly, the guide blades 211 cooperate with the rotating blades 5 to achieve a double guide effect.

[0067] Furthermore, the direction of the rotating blade 5 is opposite to that of the guide blade 211. The combination of two blades in opposite directions is cumbersome. First, it can increase the air convection effect and provide better ventilation effect; second, it can improve the air flow efficiency. The blades in opposite directions can reduce the resistance and interference between the blades, thereby improving the efficiency of the blades, and can push the air more effectively, and reduce energy consumption while providing the same air volume; third, it can reduce vibration and noise. The blades in opposite directions can balance the rotational force of the blades and reduce the vibration and noise caused by imbalance. This can provide smoother and quieter operation and improve the user experience.

[0068] The preferred configuration of the heating assembly 4 is that the heating assembly 4 is a plurality of heating sheets 41 arranged in a ring shape, a positioning groove 212 is provided at the lower end of the motor bracket 21, and the heating sheet 41 is at least partially inserted into the positioning groove 212, so as to realize the installation and fixation of the heating sheet 41;

[0069] An escape groove 411 is provided at the upper end of the heating plate 41, and the high-speed motor 3 at least partially extends into the escape groove 411, so that the structure between the components is more compact and reasonable, thereby controlling the volume and size of the entire handheld hair dryer to be smaller, which is convenient for users to use and store.

[0070] Embodiment 3

[0071] In this embodiment, refer to Figure 7 Regarding the filtering structure at the air inlet 101, the air inlet 101 is provided with an air inlet grille 81 and a metal mesh cover 82; the air inlet grille 81 is provided with a plurality of first air inlet holes 811, and the metal mesh cover 82 is provided with a plurality of second air inlet holes 821, and the size of the first air inlet holes 811 is larger than the size of the second air inlet holes 821.

[0072] The setting of the first air inlet hole 811 and the second air inlet hole 821 can ensure smooth air intake; and the sizes of the first air inlet hole 811 and the second air inlet hole 821 are limited. The first air inlet hole 811 performs a coarse screen of impurities on the air, and the second air inlet hole 821 performs a fine screen of impurities on the air, thereby ensuring the purity of the air entering the internal air duct 202, preventing impurities from causing damage to the high-speed motor 3 and the rotating fan blades 5, and providing an effective filtering and protection function.

[0073] In this embodiment, refer to Figure 4Regarding the protective structure at the air outlet 102, a protective cover 9 is provided at the air outlet 102. Since the air outlet 102 is close to the heating component 4 in the internal air duct 202, the protective cover 9 can play a role of physical space blocking to prevent the user from contacting the heating component 4, thereby providing a protective effect.

[0074] Embodiment 4

[0075] In a preferred embodiment of the present invention, referring to Figure 3 , Figure 7 The handheld housing 1 includes a housing body 11 and a housing cover 12. The housing cover 12 is assembled with the housing body 11 through a snap-fit ​​structure 13 to form a detachable shell structure, which is convenient for production installation and later disassembly and maintenance.

[0076] The shell body 11 is fixedly connected to the fan inner shell 2 by fasteners (such as screws, etc.). Furthermore, the lower part of the shell body 11 is a small diameter section 111, and the upper part of the shell body 11 expands outward to form a large diameter section 112; the combination of the small diameter section 111 and the large diameter section 112 conforms to the ergonomic design. When in use, the user holds the small diameter section 111, which is easier to hold, and the hand can be against the large diameter section 112 to provide support to prevent slipping and falling. In addition, the size of the large diameter section 112 and the small diameter section 111 varies, which can just form the installation chamber 201 between the large diameter section 112 and the fan inner shell 2.

[0077] In addition, the electric control component 6 is connected to an external power source through a cable 602 to realize power supply; or, a battery can be set in the installation chamber 201 to provide power supply, and the specific method is not particularly limited here. On the other hand, the installation chamber 201 is provided with a wire clip 603 acting on the cable 602 to constrain the cable 602 and provide protection.

[0078] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
