Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, in particular to a backpack hair dryer with a detachable power supply. Background Art

[0002] In modern urban cleaning and maintenance operations, backpack blowers, as an efficient and environmentally friendly tool, are gradually becoming one of the standard equipment for road sweeping and maintenance. This type of equipment, with its lightness and flexibility, significantly improves the efficiency of cleaning operations, and is particularly suitable for quickly cleaning up debris such as fallen leaves, dust, and snow. However, although the backpack design greatly improves the portability of the machine, existing power solutions still face certain limitations.

[0003] The power system design of most backpack hair dryers on the current market usually uses a backpack power pack to power the device. These power packs contain high-performance batteries or small fuel engines. Although they are easy to carry, they still rely on the traditional power cord connection method to connect to the hair dryer body, such as a high-power electric hair dryer disclosed in patent CN202220353800.1. This means that during use, the operator not only has to carry the hair dryer body, but also needs to manage one or more power cords that swing with the movement at the same time, which not only increases the complexity of the operation, but also may bring safety hazards, such as tripping risks, power cord wear and even electrical failures.

[0004] In addition, some designs attempt to fix the power pack by adding a bracket to the hair dryer, such as a backpack-type hair dryer disclosed in patent CN202211054609.8. However, this design also fails to get rid of the dependence on the power cord, and the additional bracket structure may increase the overall volume and weight of the equipment, affecting operational flexibility, especially in narrow spaces or operating environments that require frequent turning, thereby limiting the maneuverability of the hair dryer.

Therefore, after the staff puts on the power backpack, a certain space will be reserved between the back cover 2. The size of this space depends on the size of the groove 6. In this embodiment, the groove 6 is set to have a certain length. The air outlet 5 of the fan 3 is located at the bottom of the groove 6, that is, Fig. 9 In the position shown, when the wind is discharged, the direction of the wind will be blown upward from the air outlet 5, so the air outlet of the fan 3 will not be blocked, and the back of the staff can be cooled. Furthermore, since the air inlet of the fan 3 is located in the backpack cavity, the heat generated by the power supply assembly in the backpack cavity can be taken away, thereby achieving the effect of cooling the power supply assembly. This embodiment achieves the purpose of cooling both the power supply assembly and the back of the staff through the setting of the air outlet structure of the fan 3 and the structural setting of the back cover 2, as well as the cooperation between the two, and has higher practicality than the prior art.

[0044] Furthermore, the present embodiment is also provided with a guide housing 4, such as Fig.11 , Fig.12 and Fig.14 As shown, the guide shell 4 is used to assist the guiding of the wind flow. The guide cavity of the guide shell 4 includes an installation cavity 18 of the fan 3 and an air outlet cavity 19. The air inlet is arranged at one end of the installation cavity 18. After the fan 3 is working, the air flow in the backpack cavity enters the installation cavity 18 from the air inlet, and then under the drive of the fan 3, the air flow flows to the air outlet cavity 19, and then is blown out from the air outlet 5, thereby realizing the guidance of the wind flow, taking away the air in the backpack cavity and blowing it outside the backpack cavity, effectively dissipating the heat for the power supply component. Although the wind blown out from the air outlet 5 carries a certain amount of heat, because the heat has formed an airflow, and the airflow blown out of the backpack cavity contacts the external air and has begun to dissipate heat, the temperature of the airflow blown to the staff is relatively low relative to the temperature in the backpack cavity, and even if the formed airflow has a certain temperature, it can dissipate heat for the staff. Therefore, this embodiment can achieve the effect of dual heat dissipation through the arrangement of the guide shell 4 and the air outlet 5, which is more suitable for outdoor use by staff.

In addition, the back cover 2 of this embodiment is provided with a plurality of positioning posts 10, such as Fig.11As shown, the outer cover 1 is provided with corresponding positioning slots. During assembly, the positioning post 10 is inserted into the corresponding positioning slot, and then the positioning post 10 is penetrated by a screw and screwed into the positioning slot, so that the back cover 2 and the outer cover 1 are assembled together.

[0046] Further, such as Figure 8 As shown, a handle 16 is provided on the top of the back cover 2 of this embodiment, and shoulder strap rings 17 are provided around the back cover 2. The handle 16 is convenient for the staff to carry the power pack, and the shoulder strap rings 17 can be equipped with a shoulder strap for the staff to carry it easily.

[0047] The power supply assembly of this embodiment includes a battery cell (not shown in the drawings), a power switch 14 and a fan switch 15. The power switch 14 is used to connect the bottom socket, the side socket and the battery cell. The fan switch 15 is used to turn on and off the fan 3. The bottom socket and the side socket of this embodiment increase the usage scenario of this embodiment, that is, it can be used as follows Figure 1 As shown, it is connected to a hair dryer and can also power other devices that require power through a power cord.
