Description

Technical Field

[0001] The utility model relates to the technical field of fan products, and particularly refers to a portable high-speed fan with a new layout. Background Art

[0002] A fan refers to an electric fan, which is a tool for generating wind and cooling in hot weather. It is a device that uses electricity to drive the generation of air flow. The fan inside rotates after being powered on to form natural wind to achieve the effect of cooling. In order to facilitate people to pick up, a portable hand-held fan has appeared on the market, which can be held in the hand to achieve the cooling effect and is extremely convenient to use, making it an excellent choice for the sweltering summer.

[0003] The Chinese utility model patent with the application number 202410533479.9 discloses a hand-held fan, which includes: a housing including an air inlet, an air outlet, and an air duct connecting the air inlet and the air outlet, and the air duct extends along the length direction of the housing; a motor disposed in the air duct, the motor being a three-phase high-speed motor, and the motor includes a stator assembly, a rotor assembly, and a fan body; a wind blocking member disposed in the air duct, and the wind blocking member divides the air duct into a sub-air duct and a cavity; wherein, the wind generated when the fan body rotates passes through the sub-air duct and is blown out from the air outlet. Combining this patent (202410533479.9), it can be seen that the motor is disposed at the lower end (hand-held part) of the housing, and the power supply member (i.e., the battery) and the circuit board are both disposed at the upper end of the housing and in contact with the wind blocking member. Such a layout has the following deficiencies: First, the wind blocking member, the power supply member (i.e., the battery) and the circuit board are all disposed at the upper end of the housing, while a three-phase high-speed motor with a small volume is used at the bottom, resulting in a heavier weight at the upper end of the housing and a lighter weight at the lower end of the housing, thus affecting the user's holding feel, that is, the holding is not comfortable enough. Moreover, when the hand-held fan is working, the power supply member (i.e., the battery) will generate heat, and its heat will be transferred to the air duct and the air outlet through the wind blocking member, and then the wind blown out by the hand-held fan will have a certain amount of heat, resulting in an insufficiently ideal cooling effect and affecting the user experience.

That is, the design layout of each part of the present utility model is different from that of the existing hand-held fan, and it is a brand-new layout design, which makes the weight of the upper end of the housing lighter and the weight of the lower end of the housing heavier, so that the user's holding feel is comfortable. Moreover, the air inlet hole 101, the air duct 40 and the air outlet 103 are all arranged above the battery 3 and the circuit board 5. Even if the battery 3 generates heat, the generated heat will not enter the air duct 40, so that the air entering the air duct 40 will not be affected. That is, the wind blown by the present utility model will not be heated, ensuring that the wind blown by the present utility model is more comfortable, having a better cooling function and improving the user experience. Since the battery 3 and the circuit board 5 are first installed in a battery holder 51 to form a module and then installed in the housing 1, the installation is more convenient.

[0030] The assembly structure of the battery holder 51, the battery 3, and the circuit board 5 is as follows: One side of the battery holder 51 has a mounting groove 511, and the battery 3 is embedded in the mounting groove 511. Its assembly structure is stable and the installation is convenient. The circuit board 5 is fixed to the other side of the battery holder 51 by screws. Among them, the battery holder 51 is a plastic bracket, and several support pieces 510 are formed on the other side of the battery holder 51. The support pieces 510 support and abut against the circuit board 5, thereby ensuring that the circuit board 5 is more stably positioned on the other side of the battery holder 51 and ensuring the stability of the assembly structure.

[0031] In order to ensure that the battery 3 can be more stably installed in the mounting groove 511, the following design is also made: Two left and right distributed left clamping arms 512 and right clamping arms 513 are further provided at the lower end of the battery holder 51.

Its assembly structure is extremely stable, the structure is simple, and the installation is convenient.

[0032] In order to better control the wind speed of the air supply component 2, the following design is made: A stepless speed control roller 52 for controlling the wind speed of the air supply component 2 is provided on the circuit board 5, and the stepless speed control roller 52 partially protrudes outside the housing 1; The stepless speed control roller 52 can accurately control the wind speed of the air supply component 2, is extremely convenient to use, and the operation is simple.

[0033] The circuit board 5 is also snap-fitted with a roller bracket 53. A roller plastic cover 54 is provided on the roller bracket 53. The roller plastic cover 54 has a window 541. The stepless speed control roller 52 is rotatably installed in the roller bracket 53, and the stepless speed control roller 52 partially passes through the window 541 and extends outside the roller plastic cover 54. Among them, elastic buckles 531 are integrally formed on both sides of the roller bracket 53, and the circuit board 5 is provided with buckle positions 56 adapted to the elastic buckles 531.

[0034] A USB charging interface 55 is provided at the lower end of the circuit board 5, and the USB charging interface 55 is exposed outside the lower end face of the housing 1, which is convenient for connecting an external charging cable to charge the battery.

[0035] The air supply component 2 is arranged at the lower end of the air duct 40 and is used to draw in the outside air from the air inlet hole 101 to form wind, and the wind is discharged from the air outlet 103 after passing through the air duct 40. That is to say, in the present utility model, the air inlet hole 101 is arranged at the outer periphery of the middle part of the housing 1 and above the handheld part 102, which does not affect the air intake of the air inlet hole 101. That is, after the user holds the handheld part 102 with the hand, the air inlet hole 101 will not be covered, ensuring that the air inlet hole 101 can intake air normally. At the same time, in the present utility model, the air outlet 103 is arranged at the top or the outside of the upper end of the housing 1, and the air duct 40 is arranged between the air inlet hole 101 and the air outlet 103, so that the housing 1 of the present utility model can be set as a straight bar type or a slightly curved bar type, making the overall size of the present utility model relatively small, especially the width of the upper end is small, and the space it needs to occupy is relatively small, so that it is extremely convenient to carry. Moreover, in the present utility model, the air inlet hole 101 is arranged at the outer periphery of the middle part of the housing 1, and the air outlet 103 is arranged at the top or the outside of the upper end of the housing 1, making the length of the air duct 40 between the air inlet hole 101 and the air outlet 103 relatively short, which can effectively avoid the phenomenon of air leakage, and then ensure that the wind force is large and the air volume is also relatively large, so that the wind effect is high, which can enhance the user experience and has an excellent function of cooling and reducing temperature, making the present utility model have extremely strong market competitiveness.

[0036] In this embodiment, the housing 1 is in a straight bar shape, thereby effectively reducing the width dimension of the present utility model and making the overall size relatively small, so as to be convenient for carrying and storing.

[0037] The air inlet holes 101 are plural and are distributed in a circle at the outer periphery of the middle part of the housing 1, which can ensure the air intake volume, and further improve the wind force, air volume and wind effect of the present utility model better.

[0038] A wind duct support 4 is arranged at the upper part of the housing 1, the wind duct 40 is arranged on the wind duct support 4, and the air supply component 2 is arranged at the lower end of the wind duct support 4.

[0039] The wind duct support 4 is of an integral structure; or, the wind duct support 4 is a split two-piece structure, which includes a first wind duct frame 41 and a second wind duct frame 42 that are buckled and fixed together. The first wind duct frame 41 is provided with a buckle body 411, the second wind duct frame 42 is provided with a buckle ring 421, and the buckle body 411 and the buckle ring 421 are buckled and fixed, which is convenient for installation. Among them, the first wind duct frame 41 is further provided with a positioning flange 412, the second wind duct frame 42 is provided with a positioning groove 422 adapted to the positioning flange 412, and the positioning groove 422 and the positioning flange 412 are nested and installed with each other to form stable positioning, ensuring the stability of the assembly structure of the wind duct support 4. In this embodiment, the wind duct support 4 is a split two-piece structure.

[0040] The air duct 40 is in an L-shape, an inverted L-shape, or a reversed L-shape, so that the air outlet 103 is disposed on the outer side of the upper end of the housing 1 .

[0041] The air duct 40 includes a straight section 401 connected to the air inlet 101, an arc section 402 connected to the straight section 401 and smaller than the straight section 401, and a horizontal section 403 connected to the arc section 402, the horizontal section 403 is connected to the air outlet 103, and the air outlet 103 is arranged on the outer side of the upper end of the shell 1; the air supply component 2 is arranged at the lower end of the straight section 401. When working, the air supply component 2 draws in external air from the air inlet 101 to form wind, and the wind enters the arc section 402 with a smaller size through the straight section 401. At this time, the wind will be compressed to a certain extent, which makes it easier to increase the wind pressure and then increase the wind force. Finally, the wind is discharged through the horizontal section 403 and the air outlet 103, so as to achieve the effect of blowing out strong wind. At the same time, it uses the arc section 402 to convert the wind from the vertical direction to the horizontal direction. The inner wall of the arc section 402 is arc-shaped, which will not block the wind, but will smoothly guide the wind, thereby ensuring that a large amount of air is blown out of the air outlet 103, ensuring that the amount of air blown out is large and the wind efficiency is high.

[0042] The air outlet 103 is provided with a grid 404. The grid 404 may be integrally formed at the outlet of the horizontal section 403 and be a part of the air duct support 4. Alternatively, the grid 404 is a separate component, which is fixed at the air outlet 103 and docked with the outlet of the horizontal section 403. In this embodiment, the grid 404 is integrally formed at the outlet of the horizontal section 403 and is a part of the air duct support 4, which has a simpler structure and does not require the grid 404 to be installed additionally.

[0043] The air supply assembly 2 includes a motor bracket 21 installed in the housing 1 and a high-speed motor 22 installed in the motor bracket 21. The upper end of the motor bracket 21 is also nested with the lower end of the air duct bracket 4 to further enhance the stability of the assembly structure.

[0044] The high-speed motor 22 has an air guide channel 200 connecting the air duct 40 and the air inlet hole 101, and the lower end of the motor bracket 21 is provided with an air inlet 210 connecting the air inlet hole 101. When the high-speed motor 22 is working, it can draw in external air through the air inlet hole 101, and then enter the air duct 40 after passing through the air guide channel 200.

[0045] The high-speed motor 22 may be a ducted motor.

[0046] Specifically, the high-speed motor 22 includes a cylindrical shell 221, a high-speed motor main body 223 fixed within the cylindrical shell 221 by a number of ribs 222, and a fan blade 224 mounted on the rotating shaft at the lower end of the high-speed motor main body 223. A wind guide channel 200 communicating with the air inlet is formed between the outer periphery of the high-speed motor main body 223 and the inner wall of the cylindrical shell 221. The cylindrical shell 221 is fixed within the motor bracket 21. The structure of the high-speed motor 22 is simple and it comes with its own wind guide channel 200, making its assembly and use extremely convenient. Among them, the cylindrical shell 221 is also embedded and installed inside the lower end of the air duct bracket 4, so that the wind guide channel 200 is docked with the air duct 40. Among them, a soft rubber shock pad 23 is sleeved outside the cylindrical shell 221. The soft rubber shock pad 23 contacts the air duct bracket 4 and the motor bracket 21. Through the design of the soft rubber shock pad 23, it can effectively reduce the vibration generated by the high-speed motor main body 223 during operation, thereby reducing noise and improving the user experience while reducing vibration.

[0047] In summary, in the present utility model, the battery 3 and the circuit board 5 are installed on a battery holder 51 and then fixed inside the lower part of the outer shell 1, and the air supply assembly 2 is arranged in the middle or upper part of the outer shell 1, making the weight of the upper end of the outer shell lighter and the weight of the lower end of the outer shell heavier, so that the user's holding feel is comfortable. Moreover, the air inlet hole 101, the air duct 40, and the air outlet 103 are all arranged above the battery 3 and the circuit board 5. Even if the battery 3 generates heat, the heat generated will not enter the air duct 40, so that the air entering the air duct 40 will not be affected, that is, the air blown out by the present utility model will not be heated, ensuring that the air blown out by the present utility model is more comfortable, having a better cooling function and improving the user experience.
