[0025] To facilitate understanding of the present application, the present application is described in more detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings provide preferred embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0026] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0027] The following is a detailed description with reference to the embodiments. Figure 1 and Figure 2 A schematic diagram of an embodiment of the electronic aromatherapy device 1 of the present application is shown. The electronic aromatherapy device 1 is provided with a touch sensing element 2 on its exterior. The surface of the touch sensing element 2 is a touch surface for sensing touch operations and also constitutes a part of the exterior surface of the electronic aromatherapy device 1, having both decorative and protective functions. Figure 1 and Figure 3 A controlled object and a control circuit board 61 are provided inside the electronic aromatherapy device 1. The control circuit board 61 is electrically connected to the touch sensing element 2 and the controlled object respectively, and the control circuit board 61 is used to respond to the touch operation from the touch sensing element 2 and adjust the working state of the controlled object accordingly.

[0028] Here, the controlled object refers to a functional object within the electronic aromatherapy device 1 that can be electrically controlled by the control circuit board 61. The controlled object may include a light-emitting element 62, whose light-emitting state is controlled by the control circuit board 61. It may also include a smoke generator 3, whose start / stop, heating, atomization, and spraying functions are controlled by the control circuit board 61. The smoke generator 3 is used to control the spraying of the smoke generated by the atomized fragrance liquid in the electronic aromatherapy device 1.

[0029] Combine Figure 1 As shown, the touch sensor 2 is an annular structure mounted on the top of the electronic aromatherapy device 1. The outer surface of this annular structure also forms part of the top housing of the electronic aromatherapy device 1. A ring-shaped mounting area can be reserved on the top of the electronic aromatherapy device 1, and the annular touch sensor 2 can be mounted in this annular mounting area. In this way, the touch sensor 2 itself becomes an integral part of the outer housing of the electronic aromatherapy device 1. This is merely an example, and the annular structure and mounting area are not limited to this. Other shapes and corresponding mounting areas are also possible.

[0030] Therefore, the design of the material, shape, color, texture, etc. of the outer surface of the touch sensing element 2 is an integrated design with the overall external structural design of the electronic aromatherapy device 1. In the present application, from the perspective of the ordinary consumer's initial observation of the external structure of the electronic aromatherapy device 1, since the outer surface of the touch sensing element 2 is an integral part of the outer surface of the electronic aromatherapy device 1, the operating function of the touch sensing element 2 cannot be directly seen from visual observation. This structural setting method is a hidden setting, and no operation mark is set for the touch sensing element 2. Therefore, the technical implementation characteristics of the touch sensing element 2 of the present application in the electronic aromatherapy device 1 are dual. First, the touch sensing element 2 has the function of decorating and protecting the external surface of the device. It is a component of the surface decoration and has a protective function similar to that of the outer shell for the interior of the device. Second, the touch sensing element 2 has the human-machine interaction function of the human-machine interface, and uses the touch sensing function of its surface to perceive the user's touch operation on it, corresponding to the operation function of the functional components of the device.

[0031] From the perspective of user experience, the dual technical features of the touch-sensitive element 2 of the present application are both beneficial to improving the user experience: on the one hand, it overcomes the prior art practice of determining the interactive functional components (such as buttons, switches, knobs, and operating indicators) corresponding to the human-machine interface solely from the external structure of the electronic aromatherapy device 1. This design often undermines the integrity and aesthetics of the external structure of the electronic aromatherapy device 1. This is because the functional and operational characteristics of the product's external structure are the primary design considerations, while ignoring the fact that contemporary consumers place greater emphasis on the overall external structure and decoration of the product, and the visual experience occupies a more important position in consumer psychology. This is a key difference between the present application and the prior art. On the other hand, the touch operation of the present application itself serves as a human-machine interface. Through the diversity of touch operations, multiple functional operations of the electronic aromatherapy device 1 can be realized, which is also a unique experience for users that is different from the prior art.

[0032] Specifically, the touch-sensitive element 2 can be implemented in a variety of ways, such as an electronic touchscreen. The touchscreen can be shaped as annular, circular, rectangular, or polygonal, as needed, and can be configured to meet the desired design requirements of the electronic aromatherapy device 1. The electronic touchscreen also serves as part of the exterior surface of the electronic aromatherapy device 1. There are rigid, inflexible touchscreens and flexible, flexible touchscreens, and the thickness of the touchscreen can also be selected. Therefore, the type and configuration of the electronic touchscreen can be selected based on the exterior design requirements of the electronic aromatherapy device 1.

[0033] Furthermore, the touch sensing element 2 is an embodiment of the present invention for achieving continuous control. Other forms of control elements, such as knobs and buttons, can also achieve this continuous control. However, the touch sensing element 2 in the present invention has the dual characteristics of decoration and continuous control. Therefore, in the present invention, the electronic aromatherapy device 1 can be continuously controlled by providing a control element on the outside of the electronic aromatherapy device 1, and the control circuit board 61 is electrically connected to the control element and the light-emitting body 62 respectively. The control circuit board 61 is used to respond to the continuous control of the control element and correspondingly control the light color of the light-emitting body 62 to gradually control the light.

[0034] exist Figure 1 On the basis of Figure 2 The electronic aromatherapy device 1 is further shown as comprising a frame housing 4, which houses a smoke chamber 7 and a smoke generator 3. Specifically, the frame housing 4 comprises a main frame 42 and a transparent housing 41. The main frame 42 comprises a cover 421 and a base 422. Thus, the frame housing 4 comprises the transparent housing 41, the cover 421, and the base 422. The lower periphery of the transparent housing 41 is connected to the base 422. The cover 421 covers the upper opening of the transparent housing 41. The lower portion of the cover 421 and the upper portion of the base 422 are combined to form the main frame 42. The smoke generator 3 is disposed on the main frame 42. The transparent housing 41 covers the circumferential outer portion of the main frame 42 and, together with the main frame 42, encloses the smoke chamber 7. That is, after the cover 421 and the base 422 are combined, they enclose the transparent housing 41 to form the smoke chamber 7. The smoke generated by the electronic aromatherapy device 1 first flows into the smoke chamber 7 and then flows out to the outside through the mist outlet 43.

[0035] The touch sensor 2 is arranged on the outside of the frame housing 4. The touch sensor 2 has multiple continuous sensing positions for obtaining electrical signals from the user acting on the sensing positions. The touch sensor 2 is preferably arranged on the top of the frame housing 4. Specifically, the touch sensor 2 is arranged on the top of the main frame 42. For example, the touch sensor 2 is arranged on the upper part of the cover 421 to sense the touch operation acting on the touch sensor 2. Figure 3As shown, the light-emitting element 62 and the control circuit board 61 are both disposed within the cover 421. The light-emitting surface of the light-emitting element 62 faces the smoke chamber 7, illuminating the smoke within the smoke chamber 7 and creating a visual experience of mixed smoke. The control circuit board 61 is electrically connected to the touch sensor 2 and the light-emitting element 62, respectively. The control circuit board 61 is configured to respond to electrical signals generated by touch at various sensing locations on the touch sensor 2 and to control the lighting state of the light-emitting element 62 accordingly. The transparent housing 41 can be white or a light-colored (e.g., light blue, light green, etc.) transparent shell, or translucent shell such as black or brown. A transparent shell allows viewing inside the shell even when the internal light-emitting element 62 is off. A translucent shell primarily allows viewing inside the shell when the internal light-emitting element 62 is on.

[0036] Figure 1 and Figure 2 The cover 421 also includes a recessed groove for accommodating the smoke generator 3, which is inserted into the cover 421 through this recess. The smoke generator 3 typically contains liquid fragrance, which can be heated and atomized by spraying. The atomized smoke enters the smoke chamber 7 enclosed by the transparent housing 41 and is then ejected from the upper mist outlet 43 under the influence of wind. Therefore, an annular gap is left between the annular periphery of the annular touch sensor 2 on the upper portion of the cover 421 and the annular edge of the transparent housing 41, serving as the mist outlet 43.

[0037] Figure 3 The main diagram schematically illustrates the electrical connection between the control circuit board 61, the touch sensor 2, and the light-emitting element 62 via cables. The cover 421 also includes other structural components, which are not described here. The main components shown here are those related to touch control and light display, namely, those related to continuous touch sliding and light gradient control. The control circuit board 61 receives touch position information from the touch sensor 2 and adjusts the light state of the light-emitting element 62 according to the current state and touch position information. Of course, the control circuit board 61 also has other functions, such as controlling the fan for mist injection, controlling atomization heating, controlling the power switch, and controlling charging. The light-emitting element 62 is provided with multiple colored LED lights arranged in a ring, as well as corresponding LED display control chips.

[0038] Further, combined Figure 4, the present application also provides an embodiment of the touch sensing element 2, which includes a touch layer 21 and a sensing layer 22 stacked up and down. The sensing layer 22 is provided on the frame shell 4, and the touch layer 21 is stacked on the side of the sensing layer 22 away from the frame shell 4. The touch layer 21 can be a structural member of an insulating material such as plastic, leather, or a metal sheet painted with insulating paint. The outer surface of the touch layer 21 is a component of the surface of the electronic aromatherapy device 1, which is its dominant feature and can be directly observed; in addition, the touch layer 21 is also the contact part of the finger touch operation, which is its implicit feature, and this is why the present application requires touch to play its role as a human-machine interface. Correspondingly, the surface of the touch sensing element 2 explicitly constitutes a component of the outer surface of the electronic aromatherapy device 1, and also implicitly serves as a touch surface for sensing touch operations.

[0039] The sensing layer 22 is stacked on the inner surface of the touch layer 21 and is tightly bonded to the inner surface of the touch layer 21, such as by bonding or snapping. Distributed sensing sensors and a sensing chip 220 are provided on the sensing layer 22. Because the sensing layer 22 is tightly bonded to the inner surface of the touch layer 21, touch pressure applied to the outer surface of the touch layer 21 is sensed by the sensing sensors of the sensing layer 22, converted into touch sensing signals, and transmitted to the sensing chip 220, thereby identifying the specific location of the touch pressure applied to the touch layer 21. The sensing chip 220 is electrically connected to the control circuit board 61, which responds to the electrical signals at each sensing location and accordingly regulates the luminous state of the light-emitting element 62.

[0040] Furthermore, at least two different sensing areas are provided on the sensing layer 22. Each sensing area is insulated and independent from each other, and has no electrical connection to each other. Each sensing area typically corresponds to a metal foil, such as copper foil or aluminum foil. When a finger acts on the metal foil, for example, the touch layer 21 corresponding to the metal foil, the finger and the metal foil are equivalent to the two electrodes of a capacitor. Depending on the difference in the contact area between the finger and the metal foil, the corresponding equivalent capacitance value is also different. At the same time, the metal foil corresponding to each sensing area is also provided with a pin electrically connected to the sensing chip 220, so that the circuits for obtaining the electrical position sensing signal of each sensing area are relatively independent. When a finger presses the metal foil corresponding to different sensing areas, the equivalent capacitance value of the metal foil will change. In turn, due to the change in the equivalent capacitance value, the parameter value of the touch sensing signal input to the sensing chip 220 will change. The sensing chip 220 can correspondingly identify the change in the parameter value of the touch sensing signal generated by the equivalent capacitance, such as the change in voltage value, current value, frequency value, etc. The sensing layer 22 may include a flexible circuit board, on which the metal foil and the sensing chip 220 are arranged, thereby making the sensing layer 22 a thin layer and reducing its thickness. Figure 5As shown, the sensing layer 22 is provided with three different touch sensing areas. Adjacent touch sensing areas have intersecting contractions between them. The contractions extend from the main body (middle portion) and contract away from the main body. The contractions between adjacent touch sensing areas intersect with each other. The three touch sensing areas are arranged in a ring structure, have similar structures, and occupy substantially the same area, forming a complete ring-shaped sensing layer 22. For example, the sensing layer 22 is provided with a first touch sensing area 221, a second touch sensing area 222, and a third touch sensing area 223. For the annular sensing layer 22, both ends of the first touch sensing area 221 are contractions. Clockwise, the contraction corresponding to the starting end of the first touch sensing area 221 is the first contraction 2211, and the contraction corresponding to the ending end is the second contraction 2212. The metal foil corresponding to the first contraction 2211 is shaped like two gradually widening annular triangular areas (also called two branches), occupying a gradually increasing area. The metal foil corresponding to the second contraction 2212 is shaped like two gradually narrowing annular triangular areas. Between the first contraction 2211 and the second contraction 2212 is the middle portion of the first touch sensing area 221, which can also be considered the main body of the touch sensing area. In the clockwise direction, unlike the contraction, this middle portion no longer occupies an area that gradually changes with rotation angle. Instead, the area per arc (for example, the area of the partial annular ring corresponding to each 1° of rotation) remains constant with angle. Similarly, the ends and middle of the second and third touch sensing areas 222, 223 also have the same characteristics as the first touch sensing area 221, and will not be further described here. It can be seen that the area adjacent to the first touch sensing area 221 and the second touch sensing area 222 corresponds to the intersection between the second contraction portion 2212 of the first touch sensing area 221 and the third contraction portion 2221 of the second touch sensing area 222; the area adjacent to the first touch sensing area 221 and the third touch sensing area 223 corresponds to the intersection between the first contraction portion 2211 of the first touch sensing area 221 and the sixth contraction portion 2232 of the third touch sensing area 223; and the area adjacent to the second and third touch sensing areas 222 and 223 corresponds to the intersection between the fourth contraction portion 2222 of the second touch sensing area 222 and the fifth contraction portion 2231 of the third touch sensing area 223.

[0041] Combine Figure 5 and Figure 6As shown, the three touch sensing areas are each provided with two contraction parts, and each touch sensing area is provided with two contraction parts, and they are located at opposite ends of the touch sensing area; the two contraction parts of each touch sensing area are arranged crosswise with the contraction parts of the adjacent touch sensing area to form a complete ring structure. Furthermore, each contraction part includes multiple branch parts, and the multiple branch parts are arranged along the width direction of the sensing layer 22. The multiple here refers to two or more. Figure 5 The middle touch sensing element 2 has an annular structure. The touch layer 21 and the sensing layer 22 both have annular structures of the same shape. The first contraction portion 2211 on the sensing layer 22 indicates two forked branches. These forked branches are arranged along the radial width of the sensing layer 22. Multiple forked branches are arranged in parallel, so that there are a large number of intersecting forked branches in the radial width direction of the sensing layer 22. This prevents the user's finger from sliding on the same touch sensing area and affecting the acquisition of electrical signals at continuously changing sensing positions. Moreover, the greater the number of forked branches, the greater the probability that the user's finger can simultaneously contact forked branches on different touch sensing areas, which is conducive to obtaining more accurate touch sensing signals.

[0042] exist Figure 5 Based on, combined Figure 6As shown, for this design in which adjacent sensing areas have intersecting contraction portions, when a finger touches position P1, which is adjacent to the middle portion of the first touch sensing area 221, the touch sensing signals obtained from the three sensing areas are mainly the touch sensing signals from the first touch sensing area 221. Moreover, since the finger is adjacent to the middle portion of the first touch sensing area 221, the parameter value of this touch sensing signal is relatively large. Although the end of the sixth contraction 2232 of the third touch sensing area 223 is also touched simultaneously, the parameter value of this touch sensing signal is very small. When the finger touches position P2, this touch position can be sensed by the first contraction 2211 of the first touch sensing area 221 and also by the sixth contraction 2232 of the third touch sensing area 223. The touch pressing areas acting on these two contractions are substantially equal, and the parameter values of the touch sensing signals obtained by these two contractions are also close. However, the parameter values of these two simultaneously obtained touch sensing signals are significantly lower than the parameter value of the touch sensing signal of the first touch sensing area 221 at position P1, for example, only half the parameter value of the touch sensing signal at position P1. When the finger touches position P3, which is near the middle of the third touch sensing area 223, the touch sensing signals obtained by these three sensing areas are primarily the touch sensing signals of the third touch sensing area 223. Because it is near the middle of the third touch sensing area 223, the parameter value of this touch sensing signal is larger. Although the end of the first contracted portion 2211 of the first touch sensing area 221 is also touched simultaneously, the parameter value of this touch sensing signal is very small. Furthermore, the above description primarily illustrates that identification is performed based on the numerical value of the parameter value of the touch sensing signal. Identification can also be performed based on the magnitude of the change in the parameter value of the touch sensing signal (i.e., the amount of change). Generally, a larger change indicates that the location is touched, while a smaller or no change indicates that the location is not touched.

[0043] like Figure 7 As shown, this is an embodiment of the sensing chip 220. The chip has three touch sensing signal input pins 5#, 6# and 7#, corresponding to the symbols B, G, and R. These three pins are connected to Figure 5 and Figure 6 The metal foil of the three touch sensing areas is used to collect the touch sensing signals acting on the three touch sensing areas. Then, it is connected through two asynchronous serial ports 3# and 4# Figure 4 The sensing chip 220 can convert the three collected touch sensing signals into position code values and transmit them to the touch sensor via the connection line 224 connected to the two asynchronous serial ports. Figure 3 The control chip on the control circuit board 61 in.

[0044] Specifically, multiple position zones can be set within the annular area, and different codes (e.g., 16 different codes represented by 4 bits, or 256 different codes represented by 8 bits) can be used to represent different position zones. Based on the foregoing description, the parameter values of the three touch sensing signals obtained by sampling when different position zones are touched will also vary. Therefore, a correspondence can be established between the position code values corresponding to different position zones and the parameter values of the three touch sensing signals, achieving a one-to-one correspondence between the parameter value combinations of the three touch sensing signals and the position code values.

[0045] Furthermore, a correspondence between the position code value of the touch layer 21 and the color code value of the light display color can be established. Because the touch position of the touch layer 21 and the sensing layer 22 are closely combined, and the shapes and structures of the two layers are correspondingly matched, the position code value of the sensing layer 22 can correspond to the specific position of the touch layer 21. Figure 8 As shown, the first position area P4 of the touch layer 21 (which also corresponds to the position area of the sensing layer 22) is defined as red. When a finger touches this first position area P4, the sensing layer 22 obtains the position code value of the first position area P4 and also associates and maps this position code value with the corresponding color value, namely, red. When the sensing layer 22 senses that a finger has touched this first position area P4, the light will gradually transition from the current displayed color to red, and then remain red.

[0046] according to Figure 8 As shown, when a finger touches the touch layer 21 and slides clockwise from the first position area P4 to the second position area P5, the sensing layer 22 can sense the clockwise slide, as well as the corresponding starting and ending position areas. Accordingly, after recognizing the clockwise slide operation, the light display will gradually change from the current color in a clockwise direction, and this change will continue in a loop. Conversely, when a finger touches the touch layer 21 and slides counterclockwise from the first position area P4 to the third position area P6, the light display will gradually change from the current color in a counterclockwise direction, and this change will continue in a loop.

[0047] Figure 8 The colored ring band shown can be pasted on the outer surface of the touch layer 21 as a layer structure (such as a colored film or sticker), thereby providing an intuitive touch color indication. When the touch sensing element 2 is an electronic touch screen, the touch screen can generate the following Figure 8 The colored ring band displayed on the electronic screen shown, and the light display change according to the color corresponding to the position of the touched ring band, will not be described in detail here.

[0048] Figure 1The annular touch sensor 2 shown in the figure is only one. Multiple such annular touch sensors 2 can be provided as needed. These annular touch sensors 2 can be arranged concentrically or independently, with varying sizes and colors. Correspondingly, the illuminator 62 also includes multiple annular light strips, each controlled by a different annular touch sensor 2.

[0049] For further reference, Figures 1 to 4 The touch layer 21 extends from the outer edge toward the center of the circle to form an arc-shaped concave structure. This arc-shaped concave structure precisely matches the arc-shaped convex structure of the fingertips, increasing the contact area between the fingertips and the touch layer 21 surface and improving the sensitivity to touch operations. Therefore, this concave structure corresponds to a concave portion 211 on the surface of the touch sensor 2 away from the frame housing 4. The concave portion 211 is used to cooperate with the fingertips. For example, the concave portion 211 has a smooth arc-shaped circular surface; the concave portion 211 extends along the length of the touch sensor 2 and is recessed toward the smoke chamber 7, that is, toward the center of the device. In addition, the radial width of the touch sensing element 2 ranges from 8 to 12 mm, and the corresponding radial width of the touch layer 21 ranges from 8 to 12 mm to adapt to the size of the finger. If it is too wide, for example, the radial width of the touch layer 21 is greater than 12 mm, more contraction parts are required, which is not conducive to precise positioning; if it is too narrow, for example, the radial width of the touch layer 21 is less than 12 mm, the finger touch feeling is poor and the contact is prone to insensitivity.

[0050] In addition to the ring structure, the touch sensing element 2 can also have a variety of different shapes. For example, the touch sensing element 2 corresponds to the sensing layer 22 of the strip-shaped touch sensing element 2. The sensing layer 22 includes two different touch sensing areas, namely, a fourth touch sensing area and a fifth touch sensing area. The two adjacent touch sensing areas have an intersecting contraction portion between them. The shape of the touch sensing element 2 is not limited here.

[0051] Combine Figure 5 and Figure 6In the embodiment, the touch sensing element 2 has multiple continuous sensing positions. The touch sensing element 2 is used to obtain electrical signals from the user acting on the sensing positions. Specifically, the touch sensing element 2 senses touch sliding operations on the surface of the electronic aromatherapy device 1, correspondingly generating continuously changing touch sensing signals. The touch sensing signals are converted into touch position information and / or touch direction information. The continuous manipulation information includes touch position information and / or touch direction information. In conjunction with the touch sliding embodiment of the touch sensing element 2, a mapping relationship between touch position information and light display color information is established. Based on the mapping relationship, the light display color information corresponding to the real-time touch position information is found, and the light color of the electronic aromatherapy device 1 is controlled in real time to be consistent with the light display color information.

[0052] This application discloses an electronic aromatherapy device 1, comprising: a frame housing 4, which houses a smoke chamber 7 and a smoke generator 3, wherein the smoke generated by the smoke generator 3 can enter the smoke chamber 7; a touch sensor 2, disposed on the outside of the frame housing 4, having multiple continuous sensing positions on the touch sensor 2 for obtaining electrical signals from a user acting on the sensing positions; a light emitter 62 and a control circuit board 61, both disposed within the frame housing 4, the control circuit board 61 being electrically connected to the touch sensor 2 and the light emitter 62, respectively. The light emitter 62 faces the smoke chamber 7, so that the light emitted by the light emitter 62 illuminates the smoke within the smoke chamber 7, creating a unique smoke landscape; the control circuit board 61 is configured to respond to the electrical signals from each sensing position and accordingly adjust the light emission state of the light emitter 62. The touch sensor 2 of this device enables continuous touch control, and the color of the light emitter 62 can be gradually switched, thereby enhancing the user experience of using the electronic aromatherapy device 1. For example, when the light emitted by the light-emitting body 62 is blue, the blue light combined with the smoke creates a cold and snowy landscape effect; when the light emitted by the light-emitting body 62 is golden, the golden light combined with the smoke creates the effect of clouds and mist being parted at sunrise. Different light colors combined with smoke create different visual experiences; we will not introduce them one by one here.

Any equivalent structural transformations made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
