DETAILED DESCRIPTION
[0030] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0031] In order to make the description of the disclosed content more detailed and complete, the following is an illustrative description of the implementation methods and specific examples of the utility model; however, this is not the only form of implementing or using the specific examples of the utility model. Based on the examples in the utility model, all other examples obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.
[0033] In the description of the embodiments of the present invention, "multiple" means two or more than two, and other quantifiers are similar and should be understood. The preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features therein may be combined with each other if there is no conflict.
[0034] like Figure 1 The figure is a three-dimensional diagram of a handheld fan wind speed gear conversion device provided by an embodiment of the utility model, Figure 2 Shown Figure 1 The exploded diagram of the conversion device includes:
[0035] The touch bar 100 is provided on the handheld portion of the handheld fan (not shown in the figure) and is used to receive a touch signal from a user;
[0036] A sliding distance detection module 200 is disposed on a side away from the first touch side 110 of the touch bar 100 and is used to detect a sliding distance of a user on the touch bar 100;
[0037] A click number detection module 300 is disposed on a side away from the first touch side 110 of the touch bar 100 and is used to detect the number of clicks of the user on the touch bar 100;
[0038] and a conversion module 400 , wherein the conversion module 400 is electrically connected to the sliding distance detection module 200 and the click number detection module 300 , and is used for converting the sliding distance or the click number into a variable value of the wind speed gear.
[0039] Therefore, the touch bar 100 in the embodiment of the present invention is used to receive a touch signal from a user, and the touch bar 100 may be any structure that can be used to receive a touch signal from a user.
[0040] It should be noted that the sliding distance detection module 200 is any detection module that can detect the sliding distance of the user on the touch bar 100. For example, the sliding distance detection module 200 may include multiple thermistors. When the user slides on the touch bar 100, the first thermistor that detects the user's starting sliding position and the second thermistor that detects the user's ending sliding position can be determined. The positions of the first thermistor and the second thermistor can be predetermined during installation. In this way, the sliding distance of the user on the touch bar can be obtained by subtracting the positions of the first thermistor and the second thermistor.
[0041] It should be noted that the click detection module 300 is any detection module that can detect the number of clicks of the user on the touch bar 100. For example, the click detection module 300 may include a pressure-sensitive sensor, which can detect whether the user clicks on the touch bar. It can also include a counter in a pre-adopted chip, which can periodically receive and count the results of the pressure sensed by the pressure-sensitive sensor, thereby counting the number of times the user clicks the touch bar 100.
[0042] The conversion module 400 can be any module that can convert the sliding distance or the number of clicks into the variable value of the wind speed gear. For example, the conversion module 400 can be a chip, which can receive the sliding distance or the number of clicks, and calculate the variable value of the wind speed gear corresponding to the sliding distance or the number of clicks according to the preset numerical correspondence between the sliding distance and the variable value of the wind speed gear, and the correspondence between the number of clicks and the variable value of the wind speed gear, and output the variable value of the wind speed gear.
[0043] In an optional implementation, Figure 3 The figure shows an exploded structural diagram of a handheld fan wind speed gear conversion device provided by an embodiment of the utility model, wherein the touch bar 100 comprises:
[0044] The sliding touch bar 120 is used to receive a sliding touch signal from a user, and the sliding distance detection module 200 is disposed on a side of the sliding touch bar 120 away from the touch side;
[0045] The click touch bar 130 is used to receive the click touch signal of the user. The click times detection module 300 is arranged on a side of the click touch bar 130 away from the touch side.
[0046] It should be noted that the area of the sliding touch bar 120 and the area of the clicking touch bar 130 can be set as needed and are not limited in detail herein.
[0047] In an optional implementation, since the sliding touch bar 120 requires sliding, while the clicking touch bar 130 only requires clicking, the area of the sliding touch bar 120 can be larger than the area of the clicking touch bar 130, so as to reasonably allocate the area of the touch bar 100 and improve the adjustment efficiency of the wind speed gear.
[0048] In an optional implementation, Figure 3 As shown, the click touch bar 130 is located at the end of the touch bar 100 .
[0049] It can be understood that setting the click touch bar 130 at the end of the touch bar 100 can, on the one hand, avoid the problem that when the click touch bar 130 is set in the middle of the touch bar 100, the user's sliding of the sliding touch bar 120 will not be smooth, the user's adjustment of the wind speed gear will not be smooth, and the fan air outlet will not be smooth, which will deteriorate the user's usage experience. On the other hand, if the sliding touch bar 120 is set at the end, the user is likely to slide out of the touch bar 100 when sliding on the sliding touch bar 120, which deteriorates the effect of adjusting the wind speed gear and the user experience is not good. Since the click touch bar 130 only requires the user to click, the area of the touch bar 100 required to be occupied is not large, and naturally setting it at the end will not affect the usage effect.
[0050] In an optional implementation, Figure 3 As shown, the click touch bar 130 includes:
[0051] The first click touch bar 131 is disposed at the first end of the touch bar 100 and is used to receive a click touch signal from a user for increasing a wind speed gear;
[0052] And the second click touch bar 132 is arranged at the second end of the touch bar 100 opposite to the first end, and is used to receive a click touch signal from the user to reduce the wind speed gear.
[0053] It should be noted that the areas of the first click touch bar 131 and the second click touch bar 132 can be set according to specific needs of the application, and are not limited in detail herein.
[0054] It should be noted that the first click touch bar 131 and the second click touch bar 132 are only used to receive click touch signals. The specific implementation of increasing or decreasing the wind speed gear according to the click signal can be achieved through the chip. This function of the chip is a relatively mature technology in the existing technology and will not be described in detail here.
[0055] It can be understood that by providing two click touch bars 130 (i.e., the first click touch bar 131 and the second click touch bar 132), the wind speed gear can be increased or decreased, thereby satisfying the user's demand for wind speed to a greater extent and improving the user's experience of using the fan;
[0056] It can be further understood that the first click touch bar 131 for increasing the wind speed gear and the second click touch bar 132 for reducing the wind speed gear are respectively arranged at opposite ends of the touch bar 100. On the one hand, the sliding touch bar 120 can be located in the middle of the touch bar 100, so that the user can slide the sliding touch bar 120 smoothly, so that the wind speed gear that changes in response to the sliding distance can also be changed smoothly, and the effect of stepless speed regulation can be achieved; on the other hand, since increasing the wind speed gear and reducing the wind speed gear are two functions with completely opposite effects, the first click touch bar 131 for increasing the wind speed gear and the second click touch bar 132 for reducing the wind speed gear are arranged at opposite ends, so that the user can have a clearer memory of the functions of the two click touch bars when using them, thereby improving the user experience.
[0057] In an optional implementation, Figure 3 As shown, the sliding touch bar 120 is located in the middle of the touch bar 100 .
[0058] It can be understood that setting the sliding touch bar 120 in the middle of the touch bar 100 can, on the one hand, avoid the problem that when the click touch bar 130 is set in the middle of the touch bar 100, the user's sliding of the sliding touch bar 120 will not be smooth, which will make the user's adjustment of the wind speed gear not smooth, and then make the fan air output not smooth, which will make the user's experience worse. On the other hand, if the sliding touch bar 120 is set at the end, when the user slides on the sliding touch bar 120, it is easy to slide out of the touch bar 100, which will make the effect of adjusting the wind speed gear worse and the user experience bad.
[0059] In an optional implementation, Figure 3 As shown, the sliding distance detection module 200 includes a plurality of first capacitive sensors 210 , and the plurality of first capacitive sensors 210 are arranged along the touch sliding direction of the sliding touch bar 100 .
[0060] It should be noted that the number of the first capacitive sensors 210 can be determined according to the detection accuracy. The higher the detection accuracy, the greater the number of the first capacitive sensors 210.
[0061] It can be understood that, in the present implementation, the first capacitance sensor 210 is a capacitance sensor that converts a user's touch signal into a transformed capacitance value when the user touches the touch bar 100 .
[0062] It should be noted that the direction of the user's touch and slide can be predefined;
[0063] It can be understood that by setting multiple first capacitive sensors 210 in the direction of the user's touch sliding, and through the change of the capacitance of the capacitive sensors, it is possible to confirm whether the user touches the touch bar 100. In this way, by determining the position of the first capacitive sensor 210 at the start position of the touch sliding and the position of the first capacitive sensor 210 at the end position of the touch sliding, the touch sliding distance of the user when sliding the touch bar 120 can be obtained.
[0064] Specifically, the technology of determining the touch position by the change of the capacitance of the capacitive sensor is a relatively mature technology in the prior art, and will not be described in detail here.
[0065] It can be understood that by arranging multiple first capacitive sensors 210 along the touch sliding direction on the sliding touch bar 120, the user's moving distance on the sliding touch bar 120 can be accurately detected, and the capacitance detection method is relatively accurate, which can effectively improve the accuracy of the detected moving distance.
[0066] In an optional implementation, Figure 3 As shown, the number of the first capacitive sensors 210 is proportional to the length of the sliding touch bar 100 along the touch sliding direction.
[0067] It can be understood that in order to fully utilize the length of the sliding touch bar 100, the number of first capacitive sensors 210 can be proportional to the length of the sliding touch bar 100 along the touch sliding direction, so that the sliding distance of the user on the sliding touch bar 120 can be sufficiently large, and thus the number of wind speed gears corresponding to the sliding distance can also be greater.
[0068] It can be understood that, for the same air output range, the more wind speed gears there are, the smaller the wind speed variable value corresponding to each gear is. In this way, when the wind speed gear gradually increases or becomes smaller, the wind speed can be changed more smoothly, thereby achieving the purpose of infinitely changing fan wind speed.
[0069] In an optional implementation, Figure 3As shown, the click times detection module 300 includes a plurality of second capacitive sensors 310 , and the plurality of second capacitive sensors 310 are distributed throughout the click touch bar 130 .
[0070] It should be noted that the second capacitive sensor 210 is a capacitive sensor that converts a user's touch signal into a changed capacitance value when the user touches the touch bar 100 .
[0071] It is understandable that by distributing the second capacitive sensors 310 all over the click touch bar 130 , any click of the user at any position of the click touch bar 130 can be sensed by the second capacitive sensors 310 , which can improve the sensitivity of the user's click touch on the one hand, and improve the user's experience on the other hand.
[0072] In an optional implementation, Figure 3 As shown, the number of the second capacitive sensors 310 is proportional to the area of the click touch strip 130 .
[0073] It is understandable that the number of the second capacitive sensors 310 is proportional to the area of the click touch bar 130 , so that the second capacitive sensors 310 can be evenly distributed on the click touch bar 130 , so that the user's click on the click touch bar 130 can be detected in time.
[0074] In an optional implementation, the conversion module is a chip, and the chip has at least three capacitance signal receiving ports, each capacitance signal receiving port is used to receive the capacitance value generated by the first capacitance sensor 210 or the capacitance value generated by the second capacitance sensor 310 .
[0075] It should be noted that the number of capacitance values of the first capacitance sensor 210 or the second capacitance sensor 310 received by each capacitance signal receiving port can be set according to specific needs. As a specific example, the touch bar 100 can be divided into four sections, and the chip can have four capacitance signal receiving ports. The four capacitance signal receiving ports respectively receive the capacitance values of the capacitance sensors facing the four sections of the touch bar 100 to calculate the user's touch sliding distance or number of clicks.
[0076] The technical solution provided by the present invention is introduced in detail above. The principle and implementation mode of the present invention are explained by using specific examples in the present invention. The description of the above embodiments is only used to help understand the structure and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation mode and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
[0077] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
