Description

Technical Field

[0001] This application relates to the field of garden technology, and particularly to a hair dryer. Background Art

[0002] Hair dryers are very common tools in the garden field. Besides the garden field, they are mainly used for forest fire extinguishing, fire fighting and first aid, landscaping, dust on highway projects, snow removal, etc., and are also used in industrial production. Hair dryers are easy to start, have strong wind power, and have functions such as cleaning gravel, dust, leaves, snow blowing, and high-pressure wind fire extinguishing. Hair dryers are intelligent, can be operated by an operator just by hand, have low usage requirements, and have a broad market prospect and wide application fields.

[0003] However, the existing hair dryers have the following defects: during the use of the hair dryer, power components such as the battery pack and circuit board are prone to heat up. Especially when the hair dryer is used for a long time, it will cause the power components to overheat, leading to a series of failures; the designs of many accessories of the hair dryer are not user-friendly enough, and there are troubles in human-computer interaction during the actual use process by the operator; the air intake of the hair dryer is slow, affecting the actual operation efficiency. How to solve the problems existing in the above hair dryers is an urgent issue to be solved. Summary of the Invention

[0004] The purpose of this application is to provide a hair dryer that can solve at least one of the defects in the above background art.

[0005] To achieve the above purpose, this application provides a hair dryer, including: a barrel assembly, in which a blowing channel is provided; a handle assembly, which is installed on the barrel assembly; and a power component, which is installed in the handle assembly, and the power component is connected to the blowing channel of the barrel assembly in a through manner, so that the power component intakes air. The connection between the power component and the blowing channel of the barrel assembly enables the power component placed on the barrel assembly to intake air, accelerating the heat dissipation of the power component, solving the problem of overheating of the power component caused by too long working hours, and greatly improving the service life of the hair dryer.

[0006] Preferably, the handle assembly includes a handle, which is installed on the barrel assembly; an open cavity is provided inside the handle, and the handle and the barrel assembly form a semi-open battery compartment suitable for the intrusion of the power component, and the power component is installed in the semi-open battery compartment. The power component is placed in the semi-open battery compartment and just fits into the battery compartment.

[0007] Preferably, the air duct assembly further includes an air inlet duct and an air outlet duct. The air inlet cover, the air inlet duct, and the air outlet duct are connected in sequence. The power assembly is installed at one end of the air inlet duct close to the air inlet cover. The air inlet cover extends along the axis of the hair dryer to form the air inlet duct. The air outlet duct is fixed to the air inlet duct through a connection structure. The power assembly is installed above the air inlet duct.

[0008] Preferably, the power assembly includes a battery pack and a circuit board. Both the battery pack and the circuit board are installed on the air inlet duct, and the circuit board is placed on the battery pack. The angle α formed by the battery pack and the axis of the hair dryer is 10° - 30°. In the prior art, the battery pack of a hair dryer is usually not easy to remove. When the battery pack forms an angle of 10° - 30° with the axis of the hair dryer, it is convenient for the operator to plug and unplug the battery pack better.

[0009] Preferably, it further includes an air outlet assembly. The air outlet assembly includes an air duct and a pipe body. The pipe body is connected to the air outlet duct. The air duct is concentrically and coaxially arranged inside the pipe body. The length of the air duct is 0.7% - 0.95% of the length of the pipe body, thereby reducing the air outlet path of the hair dryer. The length of the internal air duct is slightly shorter than that of the pipe body, which can reduce the air outlet path, reduce the dissipation of wind force, and improve the working efficiency of the hair dryer at the same time.

[0010] Preferably, it further includes a handle. The handle is installed on the air inlet duct and the air outlet duct. Both the battery pack and the circuit board are installed inside the handle. The angle β formed by the handle and the axis of the hair dryer is 3° - 30°. When the handle forms an angle of 3° - 30° with the axis, it is more comfortable for the human hand to hold, which conforms to ergonomics.

[0011] Preferably, the air inlet duct and the air outlet duct are both provided with a buckle mechanism. The handle is connected to the air duct assembly through the buckle mechanism. A plurality of buckles are provided on both the air outlet duct and the air inlet duct, and the handle is fixed to the air duct assembly through the buckle mechanism.

[0012] Preferably, a groove is provided at one end of the air inlet duct close to the air inlet cover. The groove is suitable for the intrusion of the handle. A radial through hole is provided at one end of the groove far from the air inlet cover. The power assembly is connected to the blowing channel of the air duct assembly through the through hole. Digging the groove can make the handle better combined and save space at the same time. Using the through hole to connect the power assembly and the blowing channel can accelerate the heat dissipation of the power assembly and avoid failures due to overheating.

[0013] Preferably, a wind blade is provided inside the air outlet cylinder. The wind blade is concentric and coaxial with the air outlet cylinder, and the wind blades are evenly distributed along the radial direction of the air outlet cylinder. The distance between the through hole and the axis of the hair dryer is less than the distance between the edge of the wind blade and the axis of the hair dryer, thereby increasing the air intake volume of the power component. The wind entering the air outlet cylinder is guided by the wind blade, and the height of the wind blade is higher than that of the through hole, so that more wind can enter the power component through the wind blade, enhancing the heat dissipation effect of the power component.

[0014] Preferably, the battery pack is fixed by a locking tongue perpendicular to it. The handle is provided with a release button parallel to the battery pack, and the release button is connected to the locking tongue for controlling the locking tongue to release the battery pack. A spring plate is arranged in the groove of the air intake cylinder, and the spring plate is adapted to be connected with the battery pack. When the battery pack is held by hand and placed into the handle, the spring plate and the locking tongue are compressed under pressure. After the battery pack is completely inserted, the spring plate gets space to stretch and clamp the battery pack, and the locking tongue vertically abuts against the battery pack to prevent the battery pack from jumping and being damaged.

[0015] Preferably, one end of the air outlet cylinder close to the pipe body is adapted to penetrate into the pipe body, and one end of the air outlet cylinder close to the pipe body is sleeved inside the pipe body. A locking button is arranged on the air outlet cylinder for controlling the assembly and disassembly of the air outlet cylinder and the pipe body. The air outlet cylinder and the pipe body are connected in a sleeved manner, which is convenient for disassembly and assembly at any time, and is convenient for carrying and cleaning.

[0016] Compared with the prior art, the beneficial effects of the present application are as follows:

[0017] The power component is connected to the blowing channel, enabling the power component to intake air, accelerating the heat dissipation of the power component, solving the problem of overheating of the power component during operation, and greatly improving the service life of the hair dryer at the same time.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.

[0031] The terms "comprising" and "having" in the description and claims of this application, and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0032] For ease of understanding, the following can be illustrated through a specific embodiment. It should be noted that the specific structure of the hair dryer includes but is not limited to the following embodiments.

[0033] Embodiment 1:

[0034] This application provides a hair dryer, as Figure 1 、 Figure 2 and Figure 3 shown, including: a barrel assembly 1, a power assembly 2, an air outlet assembly 3, and a handle assembly 4. The power assembly 2 is installed inside the handle assembly 4. The air outlet assembly 3 is connected to the barrel assembly 1, and the handle assembly 4 is installed on the barrel assembly 1. The angle β formed by the handle assembly 4 and the axis of the hair dryer is 3° - 30°; more preferably, the angle β formed by the handle assembly 4 and the axis of the hair dryer is 6° - 10°. As Figure 2 shown, β is 7.6°, which makes it more comfortable for the human hand to hold and conforms to ergonomics.

[0035] The following elaborates on the specific structural features of each component.

[0036] As Figure 4 shown, the barrel assembly 1 includes an air inlet cover 110, an air inlet barrel 120, and an air outlet barrel 130. The air inlet cover 110, the air inlet barrel 120, and the air outlet barrel 130 are connected in sequence. The air inlet cover 110 extends along the axis of the hair dryer to form the air inlet barrel 120. The air outlet barrel 130 is fixedly connected to the air inlet barrel 120 through a connecting mechanism 102. It should be noted that the structure and installation method of the connecting mechanism 102 are well-known techniques to those skilled in the art, so no detailed elaboration will be made here. The angle formed by the air inlet cover 110 and the axis of the hair dryer is 110° - 150°. More preferably, as Figure 3 shown, the angle formed by the air inlet cover 110 and the axis of the hair dryer is 120°, so as to increase the air inlet area of the air inlet cover 110, improve the air inlet efficiency, and thus improve the working efficiency of the operator using the hair dryer.

[0037] As Figure 4As shown, the power component 2 includes a battery pack 210 and a circuit board 220. Both the battery pack 210 and the circuit board 220 are installed in the handle component 4, and the circuit board 220 is placed on the battery pack 210; the angle α formed by the battery pack 210 and the axis of the hair dryer is 10° - 30°. In the prior art, the design of the battery pack of the hair dryer is usually parallel to the axis of the hair dryer, so it does not conform to ergonomics and is not easy to remove during actual operation. In this application, the battery pack 210 forms an angle of 10° - 30° with the axis of the hair dryer. More preferably, as Figure 3 shown, the angle α formed by the battery pack 210 and the axis of the hair dryer is 10.1°, which can facilitate the operator to better insert and remove the battery pack 210. The power component 2 is connected in a through manner to the blowing channel of the air duct component 1, so that the power component 2 can intake air. The connection between the power component 2 and the blowing channel of the air duct component 1 enables the power component 2 placed on the air duct component 1 to intake air, accelerating the heat dissipation of the power component 2 and solving the problem of overheating of the power component 2 caused by too long working hours. At the same time, the service life of the hair dryer is greatly improved. The circuit board 220 is connected to multiple wires for power control of the hair dryer. The battery pack 210 is connected to the circuit board 220 through wires to provide power; the locking tongue 410 is vertically arranged on the battery pack 210. When the battery pack 210 is held by hand and placed into the handle component 4, the locking tongue 410 is compressed under pressure. When the battery pack 210 is completely inserted, the locking tongue 410 vertically abuts against the battery pack 210 to prevent the battery pack 210 from jumping and being damaged; the release button 420 is arranged in parallel with the battery pack 210 and is connected to the locking tongue 410. When the release button 420 is pressed, the cylinder connected to the release button 420 pushes the locking tongue 410 to disengage from the battery pack 210 card slot (not shown), thereby releasing the battery pack 210 and allowing it to be pulled out.

[0038] As Figure 5 shown, the air outlet component 3 includes a pipe body 310 and an air duct 320. The pipe body 310 is connected to the air outlet cylinder 130, and the air duct 320 is concentrically and coaxially arranged inside the pipe body 310. The length of the air duct 320 is 0.7% - 0.95% of the length of the pipe body 310. More preferably, the ratio of the length of the pipe body 310 to the length of the air duct 320 is 10:9, which can reduce the air path of the hair dryer's air outlet. The length of the internal air duct 320 is slightly shorter than that of the pipe body 310. The shorter air path can reduce the dissipation of wind power and improve the working efficiency of the hair dryer at the same time. The pipe body 310 is assembled by combining two identical semi-cylinders and fixed by an assembly mechanism 301. It should be known that the structure and installation method of the assembly mechanism 301 are well-known technologies to those skilled in the art, so they will not be elaborated in detail here.

[0039] As Figure 6As shown in the figure, a buckle mechanism 101 is provided on the air inlet tube 120, and the buckle mechanism 101 is used for mating connection with the handle assembly 4; a groove 121 is provided at one end of the air inlet tube 120 close to the air inlet cover 110, and the groove 121 is adapted for the intrusion of the handle assembly 4; a radial through hole 122 is provided at one end of the groove 121 away from the air inlet cover 110, and the through hole 122 is a row of strip-shaped holes. The power assembly 2 is connected to the blowing channel of the air tube assembly 1 through the through hole 122. Digging the groove 121 can make the handle assembly 4 better combined and save space at the same time; using the through hole 122 to connect the power assembly 2 and the blowing channel can accelerate the heat dissipation of the power assembly 2 and avoid failures due to overheating. A spring plate 123 is provided on the groove 121. When the battery pack 210 is held by hand and placed into the handle assembly 4, the spring plate 123 is compressed under pressure. After the battery pack 210 is completely inserted, the spring plate 123 expands to resist the battery pack 210 when it gets space, preventing the battery pack 210 from jumping and being damaged. The distance between the through hole 122 and the axis of the hair dryer is less than the distance between the edge of the wind blade 131 and the axis of the hair dryer, that is, the height of the blade of the wind blade 131 is higher than that of the through hole 122, thereby increasing the air intake of the power assembly 2. By guiding the air entering the air outlet tube 130 through the wind blade 131, more air can enter the power assembly 3 through the wind blade 131, enhancing the heat dissipation effect of the power assembly 2.

[0040] As Figure 7 shown, a buckle mechanism 101 is also provided on the air outlet tube 130, and the buckle mechanism 101 is used for mating connection with the handle assembly 4; one end of the air outlet tube 130 close to the tube body 310 is adapted to intrude into the tube body 310, and one end of the air outlet tube 130 close to the tube body 310 can be sleeved inside the tube body 310; a locking button 302 is provided on the air outlet tube 130 for controlling the assembly and disassembly of the air outlet tube 130 and the tube body 310. When assembly is required, turn on the locking button 302, insert the tube body 310 into the outer ring of the air outlet tube 130, align the positions, and finally close the locking button 302 to complete the assembly; similarly, when disassembly is required, turn on the locking button 302 and take out the tube body 310 from the outer ring of the air outlet tube 130 to complete the disassembly. The air outlet tube 130 and the tube body 310 are connected in a sleeved manner, which is convenient for disassembly and assembly at any time, and is convenient for carrying and cleaning. A wind blade 131 is provided inside the air outlet tube 130, and the wind blade 131 is concentric and coaxial with the air outlet tube 130, and the wind blade 131 is evenly distributed along the radial direction of the air outlet tube 130 to guide the air entering the air outlet tube 130.

[0041] As Figure 2As shown, a motor 132 and a fan 133 are installed inside the air outlet tube 130. The motor 132 is electrically connected to the power component 3. The motor 132 and the fan 133 are integrally connected. The fan blades 131 are arranged on the fan 133. The motor 132 and the fan 133 provide driving force for the hair dryer. When the motor 132 is turned on, it drives the fan 133 to rotate, thereby realizing the basic operation of the hair dryer. It should be noted that the structures and working principles of the motor 132 and the fan 133 are well-known technologies to those skilled in the art, so no detailed description will be given here.

[0042] As Figure 8 shown, a switch button 440 is provided at the gripping part of the handle assembly 4 for controlling the power switch of the hair dryer. The battery pack 210 is fixed in the installation groove of the handle assembly 4, and the circuit board 220 is installed inside the handle assembly 4. The handle assembly 4 includes a handle which is installed on the air duct assembly 1. An open cavity is provided inside the handle, and a semi-open battery compartment 430 is formed between the handle and the air duct assembly and is suitable for the intrusion of the power component 2. The power component 2 is installed in the semi-open battery compartment 430.

[0043] Specifically, the connection structure of the hair dryer is described in detail as follows: It includes an air duct assembly 1, a power component 2, an air outlet component 3, and a handle assembly 4. The air duct assembly 1 includes an air inlet cover 110, an air inlet tube 120, and an air outlet tube 130. The air inlet cover 110, the air inlet tube 120, and the air outlet tube 130 are connected in sequence. The air inlet cover 110 extends along the axis of the hair dryer to form the air inlet tube 120. The air outlet tube 130 is fixedly connected to the air inlet tube 120 through a connection mechanism 102. The power component 2 includes a battery pack 210 and a circuit board 220. Both the battery pack 210 and the circuit board 220 are installed inside the handle assembly 4. The circuit board 220 is placed on the battery pack 210, and the circuit board is connected to the battery pack through a wire. The air outlet component 3 includes a tube body 310 and an air duct 320. The tube body 310 is connected to the air outlet tube 130.
