Description

Technical Field

[0001] This application relates to the field of fan technology, and more specifically to a portable fan that displays wind speed. Background Technology

[0002] The wind speed adjustment of existing portable fans generally uses mechanical buttons or multi-speed switches. Users need to repeatedly press the buttons to switch between preset speeds (such as low, medium, and high), and then judge whether the wind speed meets their needs by feeling the wind speed. If the speed is not suitable, they need to cycle through the switches until they find a suitable wind speed.

[0003] Furthermore, most products lack a real-time wind speed display, leaving users unable to predict the wind speed corresponding to the current setting. They can only passively perceive the airflow intensity, leading to a blind adjustment process. This method of adjustment is not only cumbersome but can also negatively impact the user experience due to repeated switching between settings. Additionally, the lack of an intuitive wind speed display hinders users from accurately controlling the fan's operation. Summary of the Invention

[0004] In view of this, this application provides a portable fan that intuitively displays wind speed and / or battery level through visual parameters and / or numerical parameters, allowing users to understand the wind speed and battery level in real time and avoid blind adjustment.

[0005] This application provides a portable fan, comprising: a fan body including a housing having an air inlet side and an air outlet side; a fan assembly housed within the housing; a wind speed regulating device for regulating wind speed; and a display module disposed on the housing; wherein the display module displays the current wind speed and / or battery level through visual and / or numerical parameters of light, the visual parameters including at least one of light color, light brightness, light display length, and light display number of rotations.

[0006] Furthermore, the housing includes an inner shell and an outer shell, the display module is disposed between the inner shell and the outer shell, and / or on the radially inner side of the inner shell, and / or on the radially outer side of the outer shell; the fan body also includes a base, an air outlet is formed between the base and the inner shell, and the fan assembly is mounted on the rear side of the base; it also includes a battery, which supplies power to the fan assembly and the display module.

[0007] Furthermore, the inner shell and the outer shell are not completely closed in the axial direction, so that external air can enter between the inner shell and the outer shell from the air inlet side and flow out from the air outlet side; or, the inner shell and the outer shell are completely closed at least once in the axial direction.

[0008] Furthermore, the display module includes LED light strips arranged circumferentially or axially along the housing, and the lighting length or number of lighting cycles of the LED light strips is positively correlated with the current wind speed.

[0009] Furthermore, when the current wind speed is within a first threshold range, the display module displays a first color; when the current wind speed is within a second threshold range, the display module displays a second color; wherein the wind speed in the second threshold range is greater than the wind speed in the first threshold range.

[0010] Furthermore, the brightness of the display module is proportional to the current wind speed; the higher the wind speed, the higher the brightness of the display module.

[0011] Furthermore, the wind speed adjustment device is connected to an encoder, which converts the user's adjustment operation into a digital signal and transmits it to the control module. The control module controls the display module to display the current wind speed based on the digital signal through visual or numerical parameters of the light.

[0012] Furthermore, the wind speed adjustment device includes a roller button, a sliding module, or a toggle module.

[0013] Furthermore, the control module is configured to: generate a corresponding light control signal based on the pulse frequency or voltage change of the digital signal, the light control signal being used to adjust the illumination length, color switching, or brightness gradient change of the display module; and / or, the control module is configured to: generate a corresponding numerical control signal based on the pulse frequency or voltage change of the digital signal, the numerical control signal being used to adjust the changes in Arabic numerals or progress bars.

[0014] Furthermore, the control module integrates a wireless communication unit for receiving wind speed adjustment commands sent by external devices and controlling the display module according to the wind speed adjustment commands.

[0015] Compared with existing technologies, the portable fan of this application has the following advantages: The display module intuitively displays wind speed and battery level using visual parameters (light and / or numerical parameters), allowing users to understand the current wind speed and battery status in real time, avoiding blind adjustments. The double-layer shell structure not only provides installation space for the display module but may also have a beneficial effect on the fan's airflow. The encoder and control module work together to achieve precise wind speed adjustment and display control. Multiple adjustment methods and display modes meet the needs of different users, enhancing the portable fan's intelligence and user experience. Attached Figure Description

[0025] To facilitate a better understanding of the purpose, structure, features, and effects of this application, the application will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component present.

[0027] In this application, the use of terms such as "first" and "second" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0028] In the description of this application, the terms "front", "rear", "left", "right", "upper", "lower", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0029] In one embodiment, such as Figures 1 to 3The diagram shown is a schematic of the portable fan of this application. The portable fan includes a fan body 1, a fan assembly 3, a wind speed adjustment device 4, and a display module 5. The fan body 1 includes a housing 2 and a base 11, the housing 2 having an air inlet side and an air outlet side. An air outlet 23 is formed between the housing 2 and the base 11. The fan assembly 3 is housed within the housing 2 and mounted on the rear side of the base 11. The wind speed adjustment device 4 is used to adjust the wind speed. The display module 5 is disposed on the housing 2, and the display module 5 is used to display the current wind speed and / or battery level through visual and / or numerical parameters of the light, the visual parameters including at least one of light color, light brightness, light display length, and the number of light rotations.

[0030] In one embodiment, such as Figures 1 to 3 As shown, a plurality of connecting members 12 are provided between the base 11 and the housing 2. It should be understood that the plurality of connecting members 12 may be integrally formed with the base 11, integrally formed with the housing 2, integrally formed with both the base 11 and the housing 2, or formed separately. From the air inlet side to the air outlet side, the base 11 has a radially constant portion, thereby reducing wind resistance and improving wind energy. In other embodiments, the base 11 may also have a radially enlarged portion or a radially reduced portion, thereby adjusting wind pressure and wind efficiency. Furthermore, the shape of the base 11 on the air outlet side may be convex, planar, or recessed.

[0031] In one embodiment, such as Figures 1 to 3 As shown, the housing 2 includes an inner shell 21 and an outer shell 22. The inner shell 21 and the outer shell 22 are not completely closed in the axial direction, meaning that the inner shell 21 and the outer shell 22 form a through-hole space. The fan assembly 3 is installed inside the inner shell 21, with air intake on the inlet side and air outlet on the outlet side. Furthermore, the air outlet 23 drives the airflow in the through-hole space between the inner shell 21 and the outer shell 22. External air can enter the space between the inner shell 21 and the outer shell 22 from the inlet side and flow out from the outlet side, thereby increasing the air volume. In other words, the through-hole space formed by the inner shell 21 and the outer shell 22 has a multiplier effect on air volume.

[0032] Of course, in other embodiments, such as Figure 7 and Figure 8 As shown, the inner shell 21 and the outer shell 22 can also be completely closed at at least one point in the axial direction. Therefore, when the display module 5 is disposed between the inner shell 21 and the outer shell 22, the display module 5 is less susceptible to interference from gas flow. Furthermore, the overall size of the fan body 1 can be smaller, making it easier to carry.

[0033] In one embodiment, the wind speed regulating device 4 is connected to an encoder (not shown, the same below), such as Figures 1 to 3 As shown, the wind speed adjustment device 4 uses a roller button, which is connected to the encoder. When the user rotates the roller button, the encoder converts the user's rotation adjustment operation into a digital signal. The pulse frequency and phase difference of the digital signal reflect the direction and amplitude of the adjustment and are transmitted to the control module (not shown, the same below). The encoder can be an incremental encoder or an absolute encoder, and the output of the encoder is communicatively connected to the digital signal input of the control module.

[0034] In other embodiments, the wind speed regulating device 4 can also be a sliding module or a toggle module. The sliding module can be a touch-sensitive sliding adjustment or a physical slider sliding adjustment. The toggle module can cause the wind speed to continuously increase when toggled upwards, continuously decrease when toggled downwards, and remain stable when not toggled.

[0035] In one embodiment, the display module 5 includes an LED light strip arranged circumferentially or axially along the housing 2. Specifically, the display module 5 can be installed inside and / or outside the outer shell 22, and / or outside and / or inside the inner shell 21, and / or on a structure between the outer shell 22 and the inner shell 21. The housing 2 can be made of a translucent or light-transmitting material to allow the light from the LED light strip to pass through uniformly. In other embodiments, the display module 5 can also be a flexible LED light strip wrapped around the surface of the housing 2. It should be understood that the outer shell 22 and the inner shell 21 can be a single layer structure or a double layer structure.

[0036] refer to Figure 9 The control module is configured to generate a corresponding lighting control signal based on the pulse frequency or voltage change of the received digital signal, and the lighting control signal controls the display module 5 to display the corresponding effect.

[0037] Lighting display solutions can be: (Reference) Figure 4 When the wind speed is low, the LED light strip lights up fewer times; as the wind speed increases, the number of times the LED light strip lights up gradually increases. In other words, the number of times the LED light strip lights up is positively correlated with the wind speed.

[0038] Lighting display solutions can be: (Reference) Figure 4 When the wind speed is low, the LED light strip lights up the first ring. As the wind speed increases, the LED light strip lights up the second, third, fourth, and so on in sequence. That is, the order in which the LED light strip lights up is positively correlated with the wind speed.

[0039] Lighting display solutions can be: (Reference) Figure 2 andFigure 8 When the wind speed is low, the arc of the LED light strip is smaller. As the wind speed increases, the arc of the LED light strip becomes larger until the entire LED light strip is lit. That is, the length (arc range) of the LED light strip is positively correlated with the wind speed.

[0040] Lighting display solutions can be: (Reference) Figure 2 , Figure 4 and Figure 8 When the current wind speed is within the first threshold range, the LED light strip is the first color. As the wind speed increases, when it reaches the second threshold range, the LED light strip color switches to the second color. The wind speed in the second threshold range is greater than that in the first threshold range. The wind speed threshold ranges can be set to two or more, each corresponding to a different color. The first color could be blue, the second color could be green, and other threshold ranges could correspond to other colors. In other words, the LED light strip color is positively correlated with the wind speed. However, the specific correspondence between colors and wind speed threshold ranges is not limited to this example.

[0041] Lighting display solutions can be: (Reference) Figure 2 , Figure 4 and Figure 8 When the wind speed is low, the LED light strip is dim. As the wind speed increases, the brightness of the LED light strip also increases. The higher the wind speed, the higher the brightness of the display module 5. That is, the brightness of the LED light strip is positively correlated with the wind speed.

[0042] It should be understood that the above lighting display solutions can be a single solution or several solutions working together. Furthermore, the above also applies to displaying the current battery level, or several solutions working together to simultaneously display the current wind speed and battery level.

[0043] In another embodiment, reference Figure 9 The control module is configured to generate a corresponding numerical control signal based on the pulse or voltage change of the digital signal. This numerical control signal is used to adjust the changes in Arabic numerals or the progress bar. The numerical display unit is a small LED digital tube, electrically connected to the control module. (Reference) Figure 5 and Figure 6 The current wind speed parameter can be an Arabic numeral from 1 to 100, 0 to 100, 1 to 101, or 0 to 101. The specific range is not limited to these examples. Additionally, changes in wind speed can be displayed using a progress bar.

[0044] It should be understood that the light display scheme and the numerical display scheme can be selected individually or displayed simultaneously. That is, the control module can simultaneously control the display of lights and the display of numerical values. Furthermore, the above also applies to displaying the current battery level, or several schemes simultaneously displaying the current wind speed and battery level.

[0045] In one embodiment, the control module integrates a wireless communication unit, and the wind speed adjustment device 4 includes an external device. The wireless communication unit receives wind speed adjustment commands sent by the external device. After receiving the command, the control module synchronously adjusts the wind speed and controls the display module 5 to update and display the corresponding wind speed status. The external device can be a mobile app or a standalone remote control.

[0046] It should be understood that the portable fan can be one of the following: handheld fan, desktop fan, floor fan, waist-mounted fan, mask fan, etc., and is not limited to this example. (Reference) Figure 3 The portable fan also includes a battery 6, which supplies power to the fan assembly 3 and the display module 5.

[0047] The above detailed description is only an illustration of the preferred embodiment of this application and is not intended to limit the patent scope of this application. Therefore, all equivalent technical changes made using the content of this invention's specification and illustrations are included within the patent scope of this invention.
