[0045] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0046] The following is for reference. Figures 1-10 This application describes a fragrance diffuser according to an embodiment of the present application, which, taking an aromatherapy diffuser as an example, is used to diffuse the fragrance of the aromatherapy material inside the aromatherapy diffuser.

[0047] like Figure 1 and Figure 2 As shown, the fragrance diffuser includes a housing assembly and a heater 211, a light assembly 220, and a speaker assembly 240 disposed within the housing assembly. The housing assembly includes a receiving slot 1111 for holding fragrance, and an electronic component cavity (not shown) may also be formed inside the housing assembly. The heater 211, light assembly 220, and speaker assembly 240 are disposed within the electronic component cavity. In one embodiment, the housing assembly includes a shell 110 and a base 310, which are connected to form the electronic component cavity, which is located inside the shell 110 and the base 310. The receiving slot 1111 is disposed on the outer surface of the shell 110 and communicates with the outside, facilitating fragrance diffusion and replacement. The electronic component cavity and the receiving slot 1111 are spaced apart by the wall of the shell to protect the electronic components. The heater 211 is disposed within the electronic component cavity and is positioned opposite the bottom of the receiving slot 1111 to heat the receiving slot 1111, thereby accelerating the fragrance diffusion speed.

[0048] The receiving slot 1111, heater 211, and lighting assembly 220 are arranged sequentially along a first direction of the fragrance diffuser. This first direction can be consistent with the height direction of the fragrance diffuser when it is placed vertically. The first direction can also be, for example, the direction of gravity. In this application, the first direction is always taken as the direction of gravity, and will not be elaborated further below. The lighting assembly is located below the receiving slot 1111. The lighting assembly, in conjunction with the position of the receiving slot 1111, can create interesting lighting effects, such as a flame-shaped lighting effect that heats the receiving slot 1111, or a lightning effect that shocks the receiving slot 1111, providing users with a realistic landscape that mimics natural phenomena. The speaker assembly 240 is located at the end of the lighting assembly away from the heater 211, preventing the speaker assembly 240 from blocking the light from the lighting assembly and further preventing the speaker assembly 240 from being affected by the high temperature of the heater 211, thus affecting its lifespan.

[0049] The fragrance diffuser has a second direction perpendicular to the first direction. This second direction can be aligned with the width direction of the fragrance diffuser when it is placed vertically. For example, the second direction can be perpendicular to the direction of gravity. In this application, the second direction is always exemplified by the direction perpendicular to gravity, and will not be elaborated further. In the second direction of the fragrance diffuser, the maximum size of the receiving groove 1111 is larger than the size of the light assembly 220, allowing the fragrance diffuser to be shaped with a wide top and narrow middle, facilitating the combination of lighting effects and the design of more realistic structures. For example, the receiving groove 1111 imitates the cavity of a candle holder, and the light assembly 220 presents the candle flame effect. The flame is small and heats the bottom of the cavity where the candle is placed, enhancing the visual effect through design. In one embodiment, the maximum size of the speaker assembly 240 in the second direction is larger than the size of the light assembly 220 in the second direction, also for the purpose of enhancing the visual effect through design.

[0050] The heater 211 is placed below the receiving tank 1111 for better heating effect; the light assembly 220 is placed above the speaker assembly 240 so that users can see the light effect from below the receiving tank 1111. The special light effect makes the fragrance diffuser more interesting and realistic, like an open flame burning the fragrance. In addition, the use of light instead of an open flame to present the flame effect also improves safety.

[0051] The speaker assembly 240 is placed at the bottom of the lighting assembly, and the speaker assembly 240 can play sound effects that can be coordinated with the lighting effects. For example, when the lighting presents a volcanic eruption effect, the speaker emits a volcanic eruption sound, making the lighting effect more realistic and enhancing the atmosphere.

[0052] The speaker assembly 240 is located at the end of the lighting assembly 220 away from the heater 211, which can prevent the speaker assembly 240 from being affected by the heat of the heater 211.

[0053] In some embodiments, the housing assembly includes a movable housing (not shown) and a bottom housing (not shown). The movable housing is disposed above the bottom housing and is movable relative to the bottom housing, for example, the movable housing can rotate or move up and down relative to the bottom housing. The movable housing includes an outer shell 110, a light-transmitting cover 120, and a cover 330, which are sequentially fitted from the outside to the inside and are relatively fixed. The bottom housing includes a main frame 320 and a base 310, with the main frame 320 disposed on the base 310 and movably connected to the base 310 to enable the movable housing to move relative to the bottom housing. The outer shell 110 and the base 310 form the outermost housing of the fragrance diffuser, with the bottom of the outer shell 110 fitted over the base 310 to form an electronic component cavity. The light-transmitting cover 120, the cover 330, and the main frame 320 are also disposed within the electronic component cavity.

[0054] The receiving slot 211 forms a connection between the top of the outer casing 110 and the outside; the base 310 is covered by the outer casing 110 and forms an electronic component cavity, in which the heater 211, the lighting assembly 220, and the speaker assembly 240 are located. The outer casing 110 is made of glass, for example, and has good light transmittance, which can effectively display the lighting effect of the fragrance diffuser.

[0055] like Figure 1 As shown, exemplarily, the outer casing 110 includes a first end 111, a transition portion 112, and a second end 113 that are interconnected, and the first end 111, the transition portion 112, and the second end 113 are arranged sequentially along a first direction. The first end 111 may be located at the top of the transition portion 112; the second end 113 may be located at the bottom of the transition portion 112.

[0056] The first end 111 is located near the heater 211, and the first end 111 is provided with a receiving groove 1111, in which aromatherapy materials such as candles and aromatherapy crystals can be placed; the heater 211 is used to generate heat to heat the aromatherapy materials in the receiving groove 1111, so that the fragrance is released; the transition part 112 is recessed relative to the first end 111 and the second end 113 toward the central axis of the outer shell 110.

[0057] In this embodiment, the light assembly 220 is arranged along the first direction. Specifically, the light assembly 220 includes a light plate (not shown) and LED beads (not shown) disposed on the light plate. The light plate is arranged along the first direction, which can reduce the lateral dimension of the transition portion 112 of the housing 110, so that the transition portion 112 can be recessed relative to the first end 111 and the second end 113 towards the central axis of the housing 110. In this way, the fragrance diffuser presents a shape that is large at both ends and small in the middle, which not only has a special visual effect, but is also convenient for the user to hold.

[0058] like Figure 2 and Figure 3 As shown, exemplarily, the bottom housing includes a base 310 and a main frame 320. The main frame 320 is disposed on the base 310 and is fixedly connected to the base 310 to form an installation cavity (not shown). The speaker assembly 240, battery 250, pickup 260, etc. are disposed on the base 310.

[0059] The main frame 320 is mounted on the base 310, forming a mounting cavity between them. A speaker frame 340 is also provided within the mounting cavity to fix the speaker assembly 240. The speaker assembly 240 is mounted on the speaker frame 340, and the sound-emitting end of the speaker assembly 240 is spaced apart from the inner wall of the base 310, forming a resonant space (e.g., the front sound intensity of the speaker assembly 240). This example provides sufficient resonant space for low-frequency sound waves, improving low-frequency response and enhancing sound clarity.

[0060] In actual implementation, a speaker frame 340 is installed between the main frame 320 and the base 310, and the speaker assembly 240 is installed on the speaker frame 340. This prevents the speaker assembly 240 from shifting due to vibration during operation, ensuring that the speaker assembly 240 continuously outputs high-quality sound.

[0061] In actual implementation, the fragrance diffuser also includes a microphone 260, which captures sound and converts the sound signal into an electrical signal. The main control board 230 responds to the electrical signal of the sound and controls at least the switching of the working state of the lighting component 220. For example, the fragrance diffuser can control the lighting effect, brightness, and working mode switching of the lighting component 220 through sound, or control the sound switching and volume change of the speaker component 240.

[0062] The base 310 has a pickup hole 311 that communicates with the external environment. The microphone 260 is mounted on the base 310, with the pickup end of the microphone 260 facing the pickup hole 311, and the microphone 260 is positioned close to the housing 110. This forms the shortest sound wave transmission path, ensuring that external sounds (such as user voice commands) can be picked up better.

[0063] Specifically, the electronic component cavity also has a main control board 230 that is electrically connected to the microphone 260, the lighting assembly 220 and the speaker assembly 240. The main control board 230 controls the lighting assembly 220 to switch the light color or controls the speaker assembly 240 to play sound effects according to the user's voice command tone obtained by the microphone 260.

[0064] like Figures 3-5As shown, in some embodiments, the moving housing includes an outer shell 110 and a light-transmitting cover 120; the light-transmitting cover 120 is provided between the outer shell 110 and the periphery of the light assembly 220, and the light-transmitting cover 120 may have multiple layers, for example, the light-transmitting cover 120 includes: a first light-transmitting cover 121 and a second light-transmitting cover 122; the second light-transmitting cover 122 covers the outside of the light assembly 220, and the first light-transmitting cover 121 covers the outside of the second light-transmitting cover 122; through this double-layered structure, the light effect of the fragrance diffuser can be presented more gently.

[0065] The first light-transmitting cover 121 can be made of milky white plastic material and has a light-diffusing effect. It can transmit light and provide a certain light scattering effect to avoid direct light shining. The material and function of the second light-transmitting cover 122 are the same as those of the first light-transmitting cover 121, and will not be described in detail here. This allows users to not see the LED beads of the light component 220 directly through the first light-transmitting cover 121 and the second light-transmitting cover 122, thereby improving the overall aesthetics.

[0066] Specifically, the first light-transmitting cover 121 is spaced apart from the transition portion 112 of the outer shell 110, and the outer wall surface of the bottom end of the first light-transmitting cover 121 is bonded and fixed to the inner wall surface of the second end 113 of the outer shell 110; the second light-transmitting cover 122 can be spaced apart from the first light-transmitting cover 121 in the circumferential direction.

[0067] In related technologies, the first light-transmitting cover 121 and the second light-transmitting cover 122 are integrally connected; the heater 211 is connected to the circuit board inside the first light-transmitting cover 121. Thus, removing the first light-transmitting cover 121 will cause the heater 211 to be torn off and damaged, making it inconvenient for after-sales disassembly and impossible to verify which electronic component is malfunctioning.

[0068] like Figures 3-5 As shown, in some embodiments, the top of the second light-transmitting cover 122 is provided with a mounting portion 1221 for mounting the heater 211; the first light-transmitting cover 121 overlaps the mounting portion 1221 and is detachably mounted on the second light-transmitting cover 122. Specifically, the mounting portion 1221 can be a mounting slot, and the first light-transmitting cover 121 can overlap the side wall of the mounting slot. More specifically, a wiring hole is provided in the middle of the mounting slot, and when the heater 211 is installed in the mounting slot, the electrical connection wire of the heater 211 can be electrically connected to the main control board 230, which will be described later, through the wiring hole.

[0069] In this embodiment, the first light-transmitting cover 121 overlaps the mounting part 1221, that is, when the first light-transmitting cover 121 is removed from the second light-transmitting cover 122, the connection between the heater 211 and the circuit board will not be interfered with or pulled, thereby avoiding the problem of the heater 211 being damaged due to disassembly.

[0070] like Figure 4As shown, exemplarily, a heat insulation member 212 is provided between the heater 211 and the lighting assembly 220. Specifically, the heat insulation member 212 can be disposed in the mounting slot to separate the heater 211 and the lighting assembly 220; the heat insulation member 212 also has a wiring hole in the middle, and the wiring hole of the heat insulation member 212 is directly opposite to the wiring hole of the mounting slot, and the heater 211 is disposed above the heat insulation member 212.

[0071] In this example, the heater 211 generates a large amount of heat when it is working. If this heat is transferred to the lighting assembly 220 or other electronic components, it may cause the electronic components to overheat, affecting their stability and lifespan, and even causing safety hazards. By setting the heat insulation component 212, the heat generated by the heater 211 can be prevented from being transferred to the lighting assembly 220 and the surrounding electronic components.

[0072] like Figure 7 and Figure 8 As shown, in some embodiments, the fragrance diffuser further includes a main control board 230, which is located on the side of the main frame 320 facing the cover 330.

[0073] The heater 211, lighting assembly 220, and speaker assembly 240 are electrically connected to the main control board 230. The main control board 230 is positioned between the lighting assembly 220 and the speaker assembly 240, which shortens the wiring length between the main control board 230 and the lighting and speaker assemblies 220, thus facilitating their wiring connection. In actual implementation, the main control board 230 is fixed to the main frame 320 and located on the side of the main frame 320 facing the cover 330.

[0074] like Figure 6 As shown, in some embodiments, the housing assembly includes a moving housing and a bottom housing; the moving housing and the bottom housing are movably connected, and the bottom housing is provided with a control switch and a main control board 230. The control switch and the main control board 230 are electrically connected. When the moving housing moves relative to the bottom housing, the moving housing can trigger a change in the electrical signal of the control switch. The main control board 230 responds to the electrical signal to at least control the opening and closing of the heater 211. Specifically, the main control board 230 is located on the main frame 320. When the moving housing moves relative to the bottom housing, the cover 330 of the moving housing interacts with the control switch, causing a change in the electrical signal of the control switch.

[0075] Specifically, the bottom shell includes a main frame 320, the moving shell includes a cover 330, the cover 330 is movably connected to the main frame 320, the main control board 230 is located on the main frame 320, and the control switch is located on the side of the main control board 230 facing the cover 330.

[0076] The control switch includes a push switch 280, with a cover 330 slidably connected to the main frame 320. When the cover 330 moves up and down relative to the main frame 320, it can move away from or into contact with the push switch 280. The control switch also includes a rotary switch 270, with the cover 330 rotatably connected to the main frame 320. When the cover 330 rotates relative to the main frame 320, it drives a component of the rotary switch 270 to rotate, thereby changing the electrical signal of the rotary switch 270.

[0077] For example, the rotary switch 270 is used to obtain the rotation angle value of the cover 330; the main control board 230 responds to the rotation angle value; controls the lighting mode of the lighting assembly 220; for example, adjusting the brightness, color or flashing state of the light to provide personalized lighting effects and enhance the user experience; or, controls the volume of the speaker assembly 240 to provide a more suitable volume level to adapt to different usage environments or user needs.

[0078] The rotary switch 270 can be an encoder, which includes a housing, a sensor, and an encoder disk. The sensor is fixedly mounted on the housing; the encoder disk is rotatably mounted on the housing and also snap-fitted to the cover 330. The encoder disk may have a certain number of optical or magnetic marks. When the cover 330 rotates, the encoder disk also rotates. The sensor detects the marks on the encoder disk and generates pulse signals proportional to the rotation angle by calculating the changes in the marks. The main control board 230 calculates the rotation angle of the cover 330 based on these pulse signals, and then controls the lighting mode of the lighting assembly 220 or the volume of the speaker assembly 240.

[0079] For example, the push switch 280 is used to acquire a push electrical signal when the cover 330 is touched; the main control board 230 responds to the push electrical signal to control the on / off state of the light assembly 220, that is, to turn the light on or off; or to control the on / off state of the speaker assembly 240, that is, to turn the sound effect on or off.

[0080] like Figures 6-9 As shown, for example, the fragrance diffuser also includes a spring 290.

[0081] Spring 290 is located between cover 330 and main frame 320; cover 330 covers main frame 320, main frame 320 is provided with central shaft 321, cover 330 is sleeved on central shaft 321, one end of spring 290 is connected to cover 330, and the other end of spring 290 is connected to control switch or main control board 230.

[0082] Specifically, the rotary switch 270 has a limiting groove 271 around its rotating end. When the rotary switch 270 is an encoder, the limiting groove 271 is arranged around the encoder disk of the encoder.

[0083] like Figure 6 and Figure 7 As shown, one end of the spring 290 abuts against the cover 330, and the other end of the spring 290 is adapted to abut against the limiting groove 271. Figure 8 and Figure 9 As shown, the lower end face of the cover 330 is positioned opposite to the bottom surface of the limiting groove 271. When the spring 290 is not deformed, the other end of the spring 290 abuts against the bottom surface of the limiting groove 271. When the spring 290 is deformed, the other end of the spring 290 is compressed until it abuts against both the lower end face of the cover 330 and the bottom surface of the limiting groove 271. This arrangement ensures that the spring 290 is stably compressed within the limiting groove 271.

[0084] In this example, when the cover 330 is pressed, the cover 330 compresses the spring 290 and moves toward the main frame 320; when the cover 330 is not pressed, the cover 330 moves away from the main frame 320 under the restoring force of the spring 290 and moves to the initial position away from the main frame 320, thereby improving the convenience of user operation.

[0085] In actual implementation, a guide rib 322 is provided between the main frame 320 and the cover 330;

[0086] The guide rib 322 is located on the main frame 320 and contacts the cover 330; or, the guide rib 322 is located on the cover 330 and contacts the main frame 320.

[0087] Specifically, there are multiple guide ribs 322, which are arranged circumferentially along the outer wall of the main frame 320. This prevents the cover 330 from shifting during pressing or rotating, thereby optimizing the feel of pressing or rotating.

[0088] like Figure 10 As shown, by way of example, the fragrance diffuser also includes a battery 250.

[0089] The battery 250 provides energy storage to support the operation of components such as the lighting assembly 220 and the heater 211. Specifically, the battery 250 is installed in the electronic component cavity and located on the side of the main control board 230 away from the lighting assembly 220. The battery 250 is electrically connected to the main control board 230. This facilitates the connection of the lighting assembly 220 and the heater 211 to the main control board 230. Specifically, the base 310 has a power supply interface 312 that is electrically connected to the battery 250. This power supply interface 312 is used to plug in an external electrical connector to supply power to the battery 250.

[0090] like Figure 8 and Figure 10As shown, in some embodiments, a cover 330 is provided on the base 310, and a second light-transmitting cover 122 of the light-transmitting cover 120 is installed on the cover 330. The light assembly 220 is connected to the inner wall surface of the second light-transmitting cover 122 and the outer wall surface of the cover 330 respectively.

[0091] Specifically, the light assembly is mounted on the cover 330, and the inner wall of the second light-transmitting cover 122 is provided with a first limiting part 123. The first limiting part 123 abuts against one end of the light assembly 220, so that the first limiting part 123 and the cover 330 are arranged along a first direction to restrict the movement of the light assembly 220 in the first direction (see...). Figure 8 );

[0092] In one embodiment, the outer wall surface of the cover 330 is provided with a second limiting portion 331, which abuts against one end of the light assembly 220 to restrict the light assembly 220 from moving in a second direction (see...). Figure 10 ).

[0093] In this embodiment, the first limiting part 123 can abut against two sides of one end of the light assembly 220 to restrict the movement of the light assembly 220 in the first direction; the second limiting part 331 can abut against two sides of one end of the light assembly 220 to restrict the movement of the light assembly 220 in the second direction, which is perpendicular to the first direction, so as to ensure that the position of the light assembly 220 remains fixed.

[0094] In actual implementation, the first limiting part 123 can be four limiting blocks, which symmetrically abut against two sides of one end of the light assembly 220; the second limiting part 331 can be two mounting slots, with the other end of the light assembly 220 built into the two mounting slots.

[0095] like Figure 10 As shown, specifically, the light panel of the light assembly 220 includes a first segment 221, a middle segment 222, and a second segment 223 that are sequentially connected to each other and coplanarly arranged. The first segment 221 and the second segment 223 are both located on both sides of the middle segment 222, and the second segment 223 is perpendicular to the first segment 221. More specifically, the four limiting blocks of the first limiting part 123 symmetrically abut against the two sides of the first segment 221 of the light assembly 220; the two mounting slots of the second limiting part 331 are for the left and right ends of the second segment 223 of the light assembly 220 to be built into.

[0096] In this embodiment, the first segment 221, the middle segment 222, and the second segment 223 are coplanarly arranged, so that the light assembly 220 is arranged along the height direction of the outer shell 110. This reduces the lateral dimension of the transition portion 112 of the outer shell 110, making the fragrance diffuser have a shape that is large at both ends and small in the middle. At the same time, the first segment 221 and the second segment 223 are both located on both sides of the middle segment 222, and the second segment 223 is perpendicular to the first segment 221, which facilitates the first limiting part 123 to fix the first segment 221 and the second limiting part 331 to fix the second segment 223.
