[0071] The following details the implementation modes of the present application. The examples of the implementation modes are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The implementation modes described below with reference to the drawings are exemplary and are only used to explain the implementation modes of the present application, and should not be construed as a limitation to the implementation modes of the present application.

[0072] With the rapid development of China's economy, consumers' requirements for the driving environment experience of automobiles are increasing day by day. As a product that can improve the in-vehicle space environment, cooperate with the vehicle-mounted computer, and actively or passively continuously provide fragrance to create a comfortable driving atmosphere, in-vehicle fragrance devices have received key attention from the majority of consumers. Therefore, how to improve the effect of the fragrance atmosphere created by the fragrance device has become an urgent problem to be solved.

[0073] Most existing in-vehicle fragrance devices use a single carrier soaked with essence as the main source of fragrance emission. After long-term use, the fragrance will fade, and it is impossible to control the consistency of the fragrance during the service life, and it is necessary to frequently replace the fragrance bottle to maintain a high-quality fragrance experience, which may reduce users' satisfaction with the fragrance product and lead to poor market feedback. In addition, the current fragrance diffusion method of most fragrance blocks is natural diffusion, and it is impossible to quickly create a fragrance atmosphere in a short time.

[0074] To solve the above problems, an embodiment of the present application provides an aroma device 100 and a vehicle 1000. The aroma device 100 and the vehicle 1000 of the present application will be elaborated in detail below:

[0075] Please refer to Figures 1 to 3 , an embodiment of the present application provides an aroma device 100. The aroma device 100 includes a housing member 10 and a heating member 20. The housing member 10 forms a housing cavity 11 for accommodating the aroma. The heating member 20 is used to heat the aroma to generate fragrance.

[0076] Specifically, the aroma device 100 is a device that can create a specific atmosphere using volatile substances with fragrance. The aroma device 100 includes a housing member 10 and a heating member 20.

[0077] The interior of the housing member 10 is a hollow structure to form the housing cavity 11. For example, the housing member 10 includes a bottom wall 13 and an annular side wall 14. The annular side wall 14 is disposed on the bottom wall 13 and extends along the edge of the bottom wall 13 to form a tube shape, so that the housing member 10 is in a cup shape. The annular side wall 14 and the bottom wall 13 together enclose the housing cavity 11. The housing cavity 11 is used to accommodate the aroma, where the aroma is a product containing essential oils, fixatives (which may be chemical or natural components), and other possible additives, and can generate fragrance after volatilization. Among them, the aroma can be a liquid aroma or a solid aroma. The liquid aroma is a liquid product containing essential oils, fixatives (which may be chemical or natural components), and other possible additives. The solid aroma is a solid product composed of a liquid aroma and a solid medium. Both the liquid aroma and the solid aroma can volatilize into fragrance. In addition, the solid aroma contains the liquid aroma and other non-volatile substances, and only the liquid aroma can volatilize into fragrance and create an aroma atmosphere. Therefore, compared with storing a solid aroma in the housing cavity 11, when a liquid aroma is stored in the housing cavity 11, the volume of the liquid aroma accommodated in the housing cavity 11 is larger, so that the service life when using the liquid aroma is longer than when using the solid aroma. Therefore, preferably, the aroma of the present application is a liquid aroma.

[0078] The heating element 20 is a device or component that converts electrical energy or other forms of energy into heat energy. The heating element 20 is a relatively common heating element. After being powered on, the heating element 20 generates heat, converting electrical energy into heat energy to achieve the desired heating effect. For example, the material of the heating element 20 can be tinned copper wire. The heating element 20 can heat the fragrance. For example, the heating element 20 can extend into the accommodating cavity 11, such that at least a partial area of the heating element 20 is located within the accommodating cavity 11 and contacts the fragrance to heat the fragrance. Alternatively, the heating element 20 can abut against the side wall of the accommodating member 10, such that the heat of the heating element 20 can be transferred to the fragrance inside the accommodating cavity 11 through the side wall of the accommodating member 10, thereby heating the fragrance. The fragrance itself has a certain volatility, and the volatility rate of the fragrance will increase after being heated, forming an aroma. The aroma can volatilize to the outside of the fragrance device 100 (i.e., the area outside the fragrance device 100) to create a fragrance atmosphere.

[0079] During the operation of the fragrance device 100, the heating element 20 heats the fragrance in the accommodating cavity 11 to accelerate the volatilization rate of the fragrance, such that the fragrance device 100 can quickly diffuse a large amount of aroma to the outside in a short time, so as to improve the effect of the fragrance atmosphere created by the fragrance device 100 and improve the user's satisfaction with the fragrance device 100.

[0080] The fragrance device 100 according to the embodiment of the present application is provided with an accommodating member 10 and a heating element 20. The accommodating cavity 11 inside the accommodating member 10 contains the fragrance. The heating element 20 is used to heat the fragrance to form an aroma. Therefore, during the operation of the fragrance device 100, the heating element 20 can heat the fragrance to accelerate the volatilization of the fragrance, such that the fragrance device 100 can quickly diffuse a large amount of aroma to the outside in a short time, achieving a more efficient fragrance emission, so as to improve the effect of the fragrance atmosphere created by the fragrance device 100 and improve the user's satisfaction with the fragrance device 100.

[0081] Please refer to Figure 2 and Figure 3 , in some embodiments, the accommodating member 10 is made of a porous material. For example, the accommodating member 10 is made of porous ceramics, such that there are a plurality of ventilation holes on the accommodating member 10. The aperture of the ventilation holes is small, allowing the aroma to pass through. The ventilation holes are distributed throughout the accommodating member 10, such that the aroma can be emitted to the outside through various regions of the accommodating member 10, thereby making the emission of the aroma more uniform.

[0082] Specifically, when the fragrance is a liquid fragrance, the ventilation holes also allow the fragrance to slowly penetrate to the outside through the ventilation holes. At this time, the penetration speed of the fragrance can be controlled by controlling the size of the ventilation holes to ensure that the fragrance can only slowly penetrate to the outside and there will not be a large amount of fragrance leaking to the outside at the same time. The fragrance in the accommodating member 10 can slowly penetrate to the outside of the accommodating member 10 through the ventilation holes and volatilize, so as to realize the natural fragrance dispersion of the accommodating member 10. On the basis of the natural fragrance dispersion of the accommodating member 10, the heating member 20 can also accelerate the volatilization of the fragrance in the accommodating cavity 11 to generate an aroma, and the aroma can diffuse to the outside of the accommodating member 10 through the ventilation holes, so as to diffuse to the outside and create a fragrance atmosphere. In this way, under the action of the natural fragrance dispersion of the accommodating member 10 and the accelerated volatilization of the heating member 20, the present application can create a fragrance atmosphere more quickly.

[0083] Please refer to Figure 2 and Figure 3 , in some embodiments, the accommodating member 10 can also be made of a material with better sealing performance, such as glass. At this time, the accommodating member 10 is also provided with a ventilation opening communicating with the outside. For example, a ventilation opening is provided at the top of the accommodating member 10 exposed to the outside. For example, when the accommodating member 10 is a glass bottle, a bottle mouth (i.e., the ventilation opening) can be provided at the top of the glass bottle. The fragrance near the ventilation opening can volatilize naturally, and the naturally volatilized fragrance can flow to the outside through the ventilation opening. At the same time, the gaseous fragrance generated after the heating member 20 heats the fragrance can also flow to the outside through the ventilation opening. In this way, the accommodating member 10 can also realize natural fragrance dispersion, and the gaseous fragrance generated after the heating member 20 heats can also be emitted to the outside, so that the present application can create a fragrance atmosphere more quickly.

[0084] Please refer to Figures 2 to 4 , in some embodiments, the fragrance device 100 further includes an adsorbing member 30, and the adsorbing member 30 is located in the accommodating cavity 11, and the adsorbing member 30 is used for adsorbing the fragrance.

[0085] Specifically, when the fragrance is a liquid fragrance, the adsorbing member 30 can be set to adsorb the liquid fragrance. The adsorbing member 30 is an element with the ability to adsorb liquids, such as felt or absorbent cotton. Among them, the adsorbing member 30 can be made of materials with high temperature resistance, high oil absorption efficiency and corrosion resistance, such as felt and other materials. High temperature resistance can prevent the adsorbing member 30 from burning due to high temperature after the heating member 20 is short-circuited, ensuring the use safety of the fragrance device 100. High oil absorption efficiency ensures that the adsorbing member 30 can absorb more fragrance and diffuse it more quickly. At the same time, since the components of the fragrance may be corrosive, the material of the adsorbing member 30 also needs to have the ability to resist corrosion.

[0086] The adsorbing member 30 is arranged in the accommodating cavity 11 to continuously adsorb the fragrance, so as to facilitate the heating member 20 to continuously heat the fragrance adsorbed by the adsorbing member 30.

[0087] Please refer to Figures 2 to 4 , in some embodiments, the adsorbing member 30 includes a first adsorption strip 31 and two second adsorption strips 32. Both the first adsorption strip 31 and the second adsorption strips 32 are strip-shaped, so as to facilitate the first adsorption strip 31 and the second adsorption strips 32 to adsorb the fragrance. The two ends of the first adsorption strip 31 are respectively connected to one end of the two second adsorption strips 32. It can be understood that the adsorbing member 30 as a whole presents a U shape. In this way, the occupied space of the adsorbing member 30 in the accommodating cavity 11 can be enlarged, the adsorption area of the adsorbing member 30 can be increased, so as to increase the adsorption effect of the adsorbing member 30, thereby ensuring that the heating member 20 can always have enough fragrance for heating, and further ensuring the heating effect of the heating member 20.

[0088] Please refer to Figures 2 to 4 , in some embodiments, the accommodating member 10 is cup-shaped and includes a bottom wall 13 and an annular side wall 14. The annular side wall 14 is provided on the bottom wall 13. The bottom wall 13 and the annular side wall 14 together enclose the accommodating cavity 11. The first adsorption strip 31 is arranged parallel to the bottom wall 13, and the second adsorption strips 32 are arranged parallel to the annular side wall 14.

[0089] Specifically, the first adsorption strip 31 is arranged parallel to the bottom wall 13, and the second adsorption strips 32 are arranged parallel to the annular side wall 14, that is, the first adsorption strip 31 is arranged along the extending direction of the bottom wall 13, and the second adsorption strips 32 are arranged along the extending direction of the annular side wall 14, so that the shape of the adsorbing member 30 matches the shape of the accommodating cavity 11, so that the first adsorption strip 31 and the second adsorption strips 32 can be smoothly installed into the accommodating cavity 11, and the occupied space of the first adsorption strip 31 and the second adsorption strips 32 in the accommodating cavity 11 is relatively large, and the fragrance in different areas of the accommodating cavity 11 can be adsorbed.

[0090] At this time, the first adsorption strip 31 can be arranged along the edge of the bottom wall 13, and the second adsorption strips 32 can be arranged along the edge of the annular side wall 14, that is, the first adsorption strip 31 is arranged in the area of the accommodating cavity 11 close to the bottom wall 13, and the second adsorption strips 32 are arranged in the area of the accommodating cavity 11 close to the annular side wall 14, so that the first adsorption strip 31 is arranged parallel to the bottom wall 13, the second adsorption strips 32 are arranged parallel to the annular side wall 14, and the adsorbing member 30 can be arranged along the edges of three positions of the accommodating cavity 11, so as to ensure that the adsorbing member 30 can fully absorb the fragrance in the accommodating cavity 11. At the same time, the adsorbing member 30 is arranged around the edge of the accommodating cavity 11, so that the fragrance generated after being heated by the heating member 20 can quickly move to the edge of the accommodating cavity 11, and thus quickly diffuse to the outside of the fragrance device 100.

[0091] Please refer to Figure 1 and Figure 4, in some embodiments, the heating element 20 includes a first heating wire 21 and two second heating wires 22. At this time, the heating element 20 is a heating wire, and the heating wire has good formability and is easy to be processed into heating wires of different shapes to ensure that the heating element 20 can be processed into a shape that meets the requirements of the fragrance device 100. Both ends of the first heating wire 21 are respectively connected to one end of the two second heating wires 22, that is, the area of the heating element 20 located in the accommodation cavity 11 also presents a U shape. In this way, the heating area of the heating element 20 in the accommodation cavity 11 can be expanded, so as to ensure the heating effect of the heating element 20, and at the same time make the shape of the heating element 20 match that of the adsorption member 30, so as to improve the heating effect of the heating element 20 on the fragrance adsorbed by the adsorption member 30.

[0092] At least one end of the accommodation member 10 is provided with a first opening 412, so that the heating element 20 can penetrate into the accommodation cavity 11. At this time, the positional relationship between the heating element 20 and the adsorption member 30 can be various.

[0093] In one embodiment, the heating element 20 is arranged close to the adsorption member 30, that is, arranged near the adsorption member 30, so that the heating element 20 can heat the fragrance adsorbed by the adsorption member 30. In another embodiment, the heating element 20 at least partially surrounds the adsorption member 30. For example, the heating element 20 only surrounds the adsorption member 30. At this time, all or part of the heating element 20 is arranged to surround the adsorption member 30. For another example, the heating element 20 only approaches the adsorption member 30. At this time, all or part of the heating element 20 is arranged close to the adsorption member 30. For another example, part of the heating element 20 is arranged close to the adsorption member 30, and the remaining part of the heating element 20 surrounds the adsorption member 30. Or, part of the heating element 20 is arranged close to the adsorption member 30, part of the heating element 20 surrounds the adsorption member 30, and there is also part of the heating element 20 that does not surround the adsorption member 30 and is not close to the adsorption member 30.

[0094] In this way, during the operation of the fragrance device 100, the adsorption member 30 can continuously adsorb the fragrance, and the heating element 20 heats the fragrance adsorbed by the adsorption member 30 to accelerate the volatilization of the fragrance. At the same time, the amount of the fragrance stored in the adsorption member 30 is relatively stable. Therefore, the amount of the fragrance heated by the heating element 20 during the heating process is also relatively stable, so that the volume of the aroma generated and volatilized during the operation of the fragrance device 100 is relatively stable, so that the fragrance device 100 can maintain the aroma stability for a long time, and further facilitate improving the effect of the fragrance atmosphere created by the fragrance device 100 and the satisfaction of users with the fragrance device 100.

[0095] Please refer to Figure 4 , in some embodiments, the first heating wire 21 surrounds the first adsorption strip 31.

[0096] Specifically, the first heating wire 21 surrounds the first adsorption strip 31 to ensure that the heat generated by the first heating wire 21 can be transferred to the first adsorption strip 31 and the second heating wires 22 on both sides of the first heating wire 21 more evenly. Thus, the fragrance device 100 is divided into two sides with the first heating wire 21 as the center, and the heating effects of the areas on both sides of the heating element 20 are the same, making the fragrance diffusion effects on both sides the same, which is convenient for improving the user experience. At the same time, since the first heating wire 21 is spiral-shaped and has a relatively large resistance value, the first heating wire 21 can be regarded as the resistor of the heating element 20 at this time.

[0097] In this way, it can be ensured that the first heating wire 21 can effectively heat the fragrance in the first adsorption strip 31, and most of the heat generated by the resistor can be used to heat the fragrance, so as to improve the generation amount of the fragrance, enabling the fragrance device 100 to generate a large amount of fragrance in a short time, thus facilitating the fragrance device 100 to achieve efficient fragrance diffusion.

[0098] Please refer to Figure 2 and Figure 4 In some embodiments, the second heating wire 22 is arranged close to and parallel to the corresponding second adsorption strip 32, where the corresponding second adsorption strip 32 can be understood as the second adsorption strip 32 closest to the second heating wire 22. For example, the second adsorption strip 32 is located between the second heating wire 22 and the annular side wall 14, and the distance between the second adsorption strip 32 and the second heating wire 22 is less than a preset distance threshold. At this time, the second heating wire 22 is arranged parallel to the corresponding second adsorption strip 32, which can ensure that the second heating wire 22 can effectively heat each area of the corresponding second adsorption strip 32. At the same time, if the second heating wire 22 also surrounds the second adsorption strip 32, the length of the second heating wire 22 will be longer than that of the second heating wire 22 in a horizontal shape. Therefore, the second heating wire 22 does not surround the second adsorption strip 32 but is installed close to the second adsorption strip 32, which can, on the one hand, ensure that the second heating wire 22 can effectively heat the fragrance adsorbed in the second adsorption strip 32, and on the other hand, reduce the manufacturing cost of the second heating wire 22.

[0099] In this way, it can be ensured that the second heating wire 22 can effectively heat the fragrance in the second adsorption strip 32, so as to improve the generation amount of the fragrance, enabling the fragrance device 100 to generate a large amount of fragrance in a short time, thus facilitating the fragrance device 100 to achieve efficient fragrance diffusion.

[0100] Please refer to Figure 4 In some embodiments, the distances between the first heating wire 21 and the second heating wire 22 and the adsorbent 30 are less than a preset distance threshold.

[0101] Specifically, the preset distance threshold is the minimum distance between the adsorbent member 30 and the heating member 20 when the heating member 20 can efficiently heat the fragrance adsorbed by the adsorbent member 30, for example, 2 mm. When the heating member 20 surrounds the adsorbent member 30 or is arranged close to the adsorbent member 30, the distance between the heating member 20 and the adsorbent member 30 can be made less than the preset distance threshold. Therefore, the distance between the first heating wire 21 and the adsorbent member 30 is less than the preset distance threshold, and the distance between the second heating wire 22 and the adsorbent member 30 is less than the preset distance threshold. In this way, it can be ensured that both the first heating wire 21 and the second heating wire 22 can efficiently heat the corresponding areas in the adsorbent member 30.

[0102] In summary, the heating member 20 can heat the fragrance adsorbed in each area of the adsorbent member 30. When the liquid level of the fragrance inside the accommodating cavity 11 drops, the adsorbent member 30 can also adsorb the fragrance. Moreover, in some areas of the adsorbent member 30 that adsorb more fragrance, the adsorbed fragrance will move to some areas that adsorb less fragrance, making the amount of fragrance adsorbed in each area of the adsorbent member 30 relatively stable. In this way, during the use of the fragrance device 100, even if the liquid level of the fragrance drops, the amount of fragrance heated by the heating member 20 is relatively stable, and the amount of aroma generated after heating can also be maintained at a relatively stable level, thereby ensuring that the fragrance device 100 can maintain fragrance stability for a long time.

[0103] Please refer to Figure 2 , when the fragrance is a solid fragrance, there can be various positional relationships between the heating member 20 and the fragrance.

[0104] In some embodiments, the heating member 20 is arranged close to the fragrance, for example, in contact with the fragrance or installed near the fragrance, so that the heat emitted by the heating member 20 can be transferred to the fragrance and heat the fragrance, thereby ensuring a relatively high volatilization rate of the fragrance.

[0105] In other embodiments, the heating member 20 is inserted into the fragrance, that is, the heating member 20 extends into the interior of the fragrance, so as to increase the contact area between the heating member 20 and the fragrance, enabling the heat generated by the heating member 20 to be directly transferred to the fragrance and heat it, thereby reducing heat loss, which is beneficial to improving the heat utilization rate and the volatilization rate of the fragrance.

[0106] Please refer to Figure 2 , in some embodiments, the fragrance device 100 includes a temperature sensor (not shown in the figure), and the temperature sensor is used to detect the current temperature of the heating member 20.

[0107] Specifically, the fragrance device 100 is provided with a temperature sensor, which can be arranged near the heating element 20, so that the temperature sensor can detect the current temperature of the heating element 20, so as to determine the current heating condition of the heating element 20 according to the detected current temperature, and to control the heating and stop heating of the heating element 20 based on the current heating condition of the heating element 20.

[0108] Please refer to Figure 2 , in some embodiments, the fragrance device 100 includes a circuit board 50, and the circuit board 50 is connected to the heating element 20. The temperature sensor is arranged on the circuit board 50, and the circuit board 50 is used to control the heating or stop heating of the heating element 20 according to the current temperature and the preset temperature range, so that the temperature of the heating element 20 is within the preset temperature range.

[0109] Specifically, the higher the temperature of the heating element 20, the faster the volatilization efficiency of the fragrance. If the volatilization speed of the fragrance is too slow, it will affect the fragrance emission speed of the fragrance device 100. If the volatilization speed of the fragrance is too fast, it may cause the fragrance emitted by the fragrance device 100 to be too strong, thus affecting the user experience. Therefore, the preset temperature range can be set according to the temperature corresponding to the heating element 20 when the concentration of the emitted fragrance is optimal, for example, the preset temperature range is [35°C, 45°C].

[0110] The circuit board 50 is connected to the heating element 20, and the circuit board 50 can supply power to the heating element 20, so that the heating element 20 heats the fragrance after obtaining electrical energy. Therefore, the circuit board 50 can be used to control the heating or stop heating of the heating element 20.

[0111] In some embodiments, the circuit board 50 can be a mounted circuit board 50, and a plurality of components are provided on the mounted circuit board 50. The circuit board 50 can supply power to the heating element 20, so that the heating element 20 generates heat when powered on. In certain embodiments, the circuit board 50 has a control function, and it can directly control the heating or not of the heating element 20 by controlling whether to supply power to the heating element 20. Or, in some other embodiments, the circuit board 50 can only be used for power supply and does not have a control function. At this time, the fragrance device 100 can also be provided with a corresponding control device, and the control device can control the heating or not of the heating element 20 by controlling whether to supply power to the circuit board 50, that is, the control device can realize the control of the heating element 20 by means of the circuit board 50.

[0112] The circuit board 50 can control the heating element 20 to heat or stop heating according to the current temperature and the preset temperature range, so that the temperature of the heating element 20 is within the preset temperature range. First, the stop heating temperature can be determined according to the preset temperature range. The stop heating temperature is the temperature of the heating element 20 when the heating element 20 needs to stop heating. The stop heating temperature can be any temperature within the preset temperature range. For example, it can be the highest temperature, the lowest temperature or the middle value of the preset temperature range, and can be specifically determined according to the requirements in each heating process. For example, if the preset temperature range is [35°C, 45°C], then the stop heating temperature can be 35°C, 40°C or 45°C. If the stop heating temperature is the maximum temperature of the preset temperature range, on the one hand, it can ensure that the volatilization rate of the fragrance meets the requirements, and on the other hand, it can delay the speed at which the current temperature of the heating element 20 drops below the minimum temperature of the preset temperature range after the heating element 20 stops heating.

[0113] When the current temperature of the heating element 20 is less than the minimum value of the preset temperature range, the heating element 20 heats up to raise the current temperature of the heating element 20 within the preset temperature range until the current temperature of the heating element 20 reaches the stop heating temperature. When the current temperature of the heating element 20 reaches the stop heating temperature, the heating element 20 stops heating to prevent the temperature of the heating element 20 from overheating.

[0114] In this way, it can be ensured that the temperature of the heating element 20 can be maintained within the preset temperature range as much as possible, so as to ensure that the concentration of the fragrance emitted by the fragrance is better.

[0115] Please refer to Figure 2 , in some embodiments, the heating of the heating element 20 includes a temperature rising stage.

[0116] Specifically, the temperature rising stage is the stage in which the heating element 20 rises from the initial temperature when the fragrance device 100 is started to within the preset temperature range. In the temperature rising stage, the heating element 20 starts to heat, and the temperature of the heating element 20 gradually rises until it rises within the preset temperature range, so that the temperature of the heating element 20 can reach within the preset temperature range, thereby ensuring a relatively fast volatilization efficiency of the fragrance. The current temperature of the heating element 20 can be obtained by the temperature sensor, so the end moment of the temperature rising stage can be accurately determined according to the temperature sensor.

[0117] Please refer to Figure 2 , in some embodiments, the heating of the heating element 20 includes a heat preservation stage.

[0118] Specifically, the heat preservation stage is the stage of maintaining the current temperature of the heating element 20 within a preset temperature range. During the heat preservation stage, the heating element 20 can be heated or stopped based on the current temperature of the heating element 20 and the preset temperature range. When the current temperature of the heating element 20 is lower than the minimum value of the preset temperature range, the heating element 20 is heated. When the current temperature of the heating element 20 is within the preset temperature range, the heating element 20 stops heating, so that the temperature of the heating element 20 can be maintained within the preset temperature range for as long as possible.

[0119] In some embodiments, the heating of the heating element 20 includes a temperature rising stage and a heat preservation stage. The current stage in which the heating element 20 is located, whether it is the temperature rising stage or the heat preservation stage, can be determined by combining the current temperature detected by the temperature sensor. After the fragrance device 100 is started, it is considered that the heating element 20 is in the temperature rising stage. Then the temperature of the heating element 20 rises from the initial temperature to within the preset temperature range. When the current temperature of the heating element 20 is within the preset temperature range, it can be considered that the heat preservation stage is entered at this time. At this time, the circuit board 50 can maintain the temperature of the heating element 20 within the preset temperature range according to the corresponding strategy.

[0120] Please refer to Figure 2 , in some embodiments, the circuit board 50 of the fragrance device 100 continuously controls the heating element 20 to heat based on preset operating parameters. The difference between the heat production corresponding to the preset operating parameters and the heat dissipation of the fragrance corresponding to the preset temperature range is within a preset difference range.

[0121] Specifically, the preset operating parameters are the operating parameters that affect the heat production. For example, the preset operating parameter is the preset heating power. The heat production corresponding to the heating element 20 operating based on different operating parameters can be determined in advance. At the same time, the heat dissipation of the fragrance when the heating element 20 is within the preset temperature range is determined in advance. Then, the preset operating parameters with the difference between the corresponding heat production and the heat dissipation of the fragrance within the preset difference range are selected, and the heating element 20 is controlled to heat based on the preset operating parameters. Among them, the preset difference range is the range of the difference when the heat production of the heating element 20 and the heat dissipation of the fragrance can be balanced, that is, the two are roughly the same or exactly the same, so that the temperature of the fragrance can be stabilized within a small range. In one embodiment, the preset difference range is [-0.15W, 0.15W]. When the difference between the heat production of the heating element 20 and the heat dissipation of the fragrance is within the preset difference range, it can be considered that the heat production of the heating element 20 and the heat dissipation of the fragrance are balanced, and at this time, the temperature of the fragrance can be stabilized within a small range. When the difference between the heat production of the heating element 20 and the heat dissipation of the fragrance is outside the preset difference range, it can be considered that the heat production of the heating element 20 and the heat dissipation of the fragrance are unbalanced, and at this time, the temperature of the fragrance fluctuates greatly.

[0122] After the fragrance device 100 operates, it can continuously control the heating element 20 to heat according to the preset operating parameters. Since the initial temperature of the heating element 20 is basically lower than the preset temperature range, at this time, the heat output of the heating element 20 is greater than the heat dissipation of the fragrance, and the temperature of the heating element 20 gradually rises until the temperature of the heating element 20 rises to the preset temperature range. When the temperature of the heating element 20 rises to the preset temperature range, the difference between the heat output of the heating element 20 and the heat dissipation of the fragrance is within the preset difference range, so that the final heat output of the heating element 20 and the heat dissipation of the fragrance are balanced, and thus the current temperature of the heating element 20 can finally be maintained within the preset temperature range. It can be understood that a temperature sensor does not need to be set at this time. In this way, during the operation of the fragrance device 100, continuously controlling the heating element 20 to heat according to the preset operating parameters can also ensure that the temperature of the heating element 20 can rise and be maintained within the preset temperature range for a long time.

[0123] In another embodiment, control can be combined with a temperature sensor. After the fragrance device 100 operates, it can heat based on the maximum heating power until the current temperature obtained based on the temperature sensor is within the preset temperature range to accelerate the heating rate. When the current temperature is within the preset temperature range, the heating element 20 is continuously controlled to heat based on the preset operating parameters to maintain the current temperature of the heating element 20 within the preset temperature range.

[0124] In this way, by controlling the heating element 20 to continuously heat according to the preset operating parameters, when the current temperature of the heating element 20 is within the preset temperature range, the heat output of the heating element 20 and the heat dissipation of the fragrance can be kept balanced, so as to ensure that the temperature of the heating element 20 can always be within the preset temperature range, and further ensure the fragrance emission effect of the fragrance device 100.

[0125] Please refer to Figure 2 , in some embodiments, the preset operating parameter is the preset heating power.

[0126] Specifically, the heat output is greatly affected by the heating power. Therefore, when the temperature of the heating element 20 is within the preset temperature range, the heat outputs corresponding to different heating powers can be determined in advance. Then, within the preset temperature range, a preset heating power is selected whose corresponding difference between the heat output and the heat dissipation of the fragrance is within the preset difference range. For example, the value range of the preset heating power is [0.85W, 1.15W], and preferably, it can be 1W.

[0127] In this way, after the heating element 20 operates according to the preset heating power, the current temperature of the heating element 20 can always be maintained at the temperature corresponding to the preset heating power, and even if there are fluctuations, they are only small fluctuations, so as to ensure that the current temperature of the heating element 20 is always maintained within the preset temperature range, and further ensure the heating effect of the heating element 20.

[0128] Please refer to Figures 1 to 3 , in some embodiments, the fragrance device 100 includes a housing 40, and the accommodating member 10 is located inside the housing 40.

[0129] Specifically, an installation space is formed inside the housing 40, and the accommodating member 10 is installed in the installation space to facilitate fixing the accommodating member 10, thereby fixing the heating member 20. At the same time, the housing 40 is used to protect the accommodating member 10 and the heating member 20 to prevent the accommodating member 10 and the heating member 20 from being damaged by the outside. The installation space can be an integrated space or spaces in different regions, that is, the housing 40 and the heating member 20 can be installed together or separately.

[0130] Please refer to Figure 2 and Figure 3 , in some embodiments, the housing 40 includes a cylinder body 41 and a cover body assembly 42. The cover body assembly 42 is connected to one end of the cylinder body 41 to form a receiving cavity, and the accommodating member 10 is located in the receiving cavity.

[0131] Specifically, the housing 40 includes a cylinder body 41 and a cover body assembly 42. The cylinder body 41 is a hollow structure, and one end of the cylinder body 41 is connected to the cover body assembly 42 to form a receiving cavity. The accommodating member 10 is located in the receiving cavity to fix and protect the accommodating member 10 by using the cylinder body 41 and the cover body assembly 42. At least a part of the heating member 20 extends into the accommodating member 10. At this time, a part of the structure of the heating member 20 can be located in the cover body assembly 42, and another part of the structure extends into the accommodating member 10, or a part of the heating member 20 is located in the receiving cavity, and another part of the structure extends into the accommodating member 10.

[0132] In this way, the housing 40 can be disassembled into the cylinder body 41 and the cover body assembly 42 to use the accommodating cavity 11 formed by the cylinder body 41 and the cover body assembly 42 to accommodate the accommodating member 10, and facilitate the assembly of the housing 40, thereby facilitating the assembly of the fragrance device 100.

[0133] Please refer to Figures 1 to 3 , in some embodiments, through holes 411 are formed on the side surface of the cylinder body 41. The through holes 411 are configured to expose at least a part of the accommodating member 10 to allow the fragrance generated after the fragrance volatilizes to be emitted from the through holes 411. For example, the cylinder body 41 is a cuboid, and the cylinder body 41 includes four side surfaces, and one or more through holes 411 can be formed on each side surface. After the accommodating member 10 is installed in the installation space, the accommodating member 10 can communicate with the outside, so that the fragrance generated after the fragrance volatilizes is emitted to the outside from the through holes 411.

[0134] Among them, the position of the through hole 411 needs to be determined according to the position where the fragrance leaves the accommodating member 10. In one embodiment, the accommodating member 10 is a porous material, and the fragrance passes through the accommodating member 10 through the ventilation holes on the side surface of the accommodating member 10. Therefore, the through hole 411 needs to be provided in the area of the housing 40 corresponding to the side surface of the accommodating member 10, so that the fragrance passing through the ventilation holes on the side surface of the accommodating member 10 can flow to the through hole 411 and then be dissipated to the outside. In another embodiment, the accommodating member 10 is made of a material with better sealing performance, and the accommodating member 10 is provided with a vent. The fragrance leaves the accommodating member 10 through the vent. Therefore, at this time, the through hole 411 needs to be provided in the area of the housing 40 corresponding to the vent of the accommodating member 10, so that the fragrance leaving the accommodating member 10 through the vent can flow to the through hole 411 and then be dissipated to the outside.

[0135] In this way, after the fragrance is generated in the accommodating cavity 11, it can be dissipated to the outside through the accommodating member 10 and the through hole 411 in sequence to realize fragrance dissipation and ensure that the fragrance device 100 can create a fragrance atmosphere in the outside world.

[0136] In another embodiment, the housing 40 is a breathable material. At this time, the through hole 411 may not be provided in the housing 40, so that the fragrance can move through the housing 40 to the outside.

[0137] Please refer to Figure 2 and Figure 3 , in some embodiments, a first opening 412 is provided at one end of the cylinder 41 close to the cover assembly 42, and the cover assembly 42 includes a seal 421, and the seal 421 seals the first opening 412.

[0138] Specifically, a first opening 412 is provided at one end of the cylinder 41 close to the cover assembly 42 to facilitate the installation of the accommodating member 10 into the inside of the cylinder 41 through the first opening 412. The cover assembly 42 may include a seal 421. At this time, the seal 421 abuts against the first opening 412, so that the seal 421 can seal the first opening 412 to prevent external substances from entering the inside of the cylinder 41 through the first opening 412, and at the same time, it can also prevent the accommodating member 10 located inside the cylinder 41 from falling out of the fragrance device 100 through the first opening 412.

[0139] Please refer to Figure 2 and Figure 3 , in some embodiments, the seal 421 includes a sealing plate 4211, and the sealing plate 4211 seals the first opening 412.

[0140] Specifically, the shape and size of the sealing plate 4211 can match the shape and size of the first opening 412, so that after the sealing plate 4211 is connected to the cylinder body 41, the sealing plate 4211 can also seal the first opening 412. At this time, one end of the cylinder body 41 close to the cover assembly 42 is tightly combined with the sealing plate 4211. In this way, the cylinder body 41 can be used to fix the sealing plate 4211 and even the entire seal 421, preventing the sealing plate 4211 from shaking during use, which may cause the sealing plate 4211 to be difficult to continuously seal the first opening 412, thus ensuring that the sealing effect of the seal 421 is always better.

[0141] Please refer to Figure 2 and Figure 3 , in some embodiments, the accommodating member 10 is cup-shaped and has a second opening 12 at one end facing the cover assembly 42, and the sealing plate 4211 seals the second opening 12.

[0142] Specifically, the accommodating member 10 is cup-shaped, and the bottom wall 13 and the annular side wall 14 of the accommodating member 10 jointly enclose an accommodating cavity 11. The bottom wall 13 is located at one end of the accommodating member 10 facing away from the cover assembly 42, and a second opening 12 is formed at one end of the annular side wall 14 facing the cover assembly 42, so that the heating member 20 can extend into the accommodating cavity 11, increasing the contact area between the heating member 20 and the fragrance, thereby facilitating the improvement of the fragrance volatilization rate.

[0143] The fragrance may be partially corrosive, and some areas of the heating member 20 may be affected in their normal operation after contacting the fragrance, while some areas will not be affected in their normal operation after contacting the fragrance. Therefore, when the accommodating member 10 is provided with the second opening 12, the fragrance may leak from the second opening 12 to other places.

[0144] The sealing plate 4211 is a flat sealing element used to prevent the leakage of fluids (such as water, gas, chemicals, and hydrocarbons). Among them, the sealing plate 4211 needs to be made of corrosion-resistant material to ensure that the sealing plate 4211 can continuously seal the second opening 12.

[0145] The sealing plate 4211 abuts against the second opening 12, and the area of the sealing plate 4211 is at least greater than or equal to the area of the second opening 12, so that the sealing plate 4211 can seal the second opening 12 of the accommodating member 10, thereby sealing the accommodating cavity 11, ensuring that the fragrance inside the accommodating cavity 11 is not directly exposed to the outside, and protecting other components of the fragrance device 100 from being damaged.

[0146] Please refer to Figure 2 and Figure 3, in some embodiments, the seal 421 includes a first boss 4212 disposed on the seal plate 4211. A second boss 15 is provided on the accommodating member 10 near the second opening 12. The first boss 4212 is sleeved on the second boss 15, so that the seal 421 seals the second opening 12.

[0147] Specifically, the raised first boss 4212 can be provided on the seal plate 4211. Near the second opening 12 of the accommodating member 10, that is, at one end facing the cover assembly 42, a second boss 15 is provided. For example, the annular side wall 14 of the accommodating member 10 can be divided into an inner wall and an outer wall. In the end of the accommodating member 10 facing the cover assembly 42, the length of the inner wall is longer than that of the outer wall, so that the end of the accommodating member 10 facing the cover assembly 42 forms an inner-long and outer-short second boss 15. The diameter of the first boss 4212 is larger than that of the second boss 15, so that the first boss 4212 can be sleeved on the second boss 15, and thus the seal 421 can seal the second opening 12.

[0148] In some embodiments, the cylinder 41 can also be combined to enhance the bonding stability between the seal 421 and the accommodating member 10. When the accommodating member 10 is installed in the cylinder 41, the second boss 15 will enclose a groove with the inner surface of the cylinder 41. The first boss 4212 can extend into the groove. When the first boss 4212 abuts against the bottom of the groove, it can be considered that the first boss 4212 is sleeved on the second boss 15 at this time. At this time, the seal 421 abuts against the accommodating member 10 and is connected to the cylinder 41, thus completing the installation of the seal 421. At the same time, after the first boss 4212 abuts against the bottom of the groove, glue can be applied around the area where the first boss 4212 and the groove cooperate to further improve the sealing effect of the fragrance. The glue used can be a structural glue that can be used for connecting ceramics and plastics.

[0149] In this way, the combination between the seal 421 and the accommodating member 10 can be realized, which is convenient for completing the assembly of the fragrance device 100. At the same time, it can be ensured that the seal 421 can seal the accommodating cavity 11 after combination, so as to ensure that the fragrance does not leak.

[0150] Please refer to Figure 2 and Figure 3 , in some embodiments, the fragrance device 100 further includes a circuit board 50. The circuit board 50 is disposed in the cover assembly 42 and is located on the side opposite to the seal 421 and the accommodating member 10.

[0151] Specifically, the circuit board 50 is disposed inside the cover assembly 42. For example, a groove is provided inside the cover assembly 42 to mount the circuit board 50, so as to facilitate protecting the circuit board 50 by the cover assembly 42. The fragrance has certain corrosiveness, and the circuit board 50 cannot be directly in contact with the fragrance. Therefore, the circuit board 50 is located on the side of the seal 421 opposite to the accommodating member 10, so as to isolate the circuit board 50 and the fragrance by the seal 421, thereby preventing the fragrance from damaging the circuit board 50 and improving the safety of the circuit board 50.

[0152] Please refer to Figure 2 and Figure 3 , in some embodiments, the seal 421 is provided with a first mounting hole 4213, the heating member 20 is a heating wire, and both ends of the heating member 20 are connected to the circuit board 50 and extend into the accommodating cavity 11 through the first mounting hole 4213.

[0153] Specifically, the heating member 20 is a heating wire, so that the shape of the heating member 20 can be adjusted as needed. The fragrance has certain corrosiveness, and the circuit board 50 cannot be directly in contact with the fragrance, but the heating member 20 needs to be in contact with the fragrance. Therefore, a first mounting hole 4213 can be provided on the seal 421, for example, a first mounting hole 4213 is provided on the sealing plate 4211 for the heating member 20 to pass through. After one end of the heating member 20 is connected to the circuit board 50, the other end of the heating member 20 passes through the first mounting hole 4213, and thus through the second opening 12 until it extends into the accommodating cavity 11. Then the other end of the heating member 20 extends out of the accommodating cavity 11 and passes through the first mounting hole 4213 again and is finally connected to the circuit board 50. At the same time, at least the area of the heating member 20 in direct contact with the fragrance should be made of corrosion-resistant material, so as to ensure that the heating member 20 can stably heat the fragrance.

[0154] The number of the first mounting holes 4213 can be one or more. For example, it can be one, two or four, and can be specifically determined according to the structure of the heating member 20. In one embodiment, the heating member 20 has a U-shaped structure and the heating member 20 needs to pass through the first mounting hole 4213 twice, and at this time the first mounting hole 4213 can be provided as two.

[0155] In this way, a first mounting hole 4213 can be provided on the seal 421 to use the seal 421 to seal the second opening 12, ensure that the fragrance will not leak, prevent the fragrance from directly contacting the circuit board 50, and ensure that after the heating member 20 is connected to the circuit board 50, it can extend into the accommodating cavity 11 through the first mounting hole 4213 and the second opening 12 and heat the fragrance.

[0156] Please refer to Figure 2 and Figure 3, in some embodiments, the cover assembly 42 includes a loading member 422. The loading member 422 is connected to the cylinder body 41, and a seal 421 is located between the loading member 422 and the accommodating member 10.

[0157] Specifically, the cover assembly 42 includes a loading member 422. The loading member 422 can be connected to the cylinder body 41, and the connection method can be a detachable connection method and a non-detachable connection method. The detachable connection methods include threaded connection, snap connection, and hinge connection. The non-detachable connection methods include hemming connection, riveting connection, bonding connection, and welding connection, etc.

[0158] The seal 421 is located between the loading member 422 and the accommodating member 10. The loading member 422 can be used to load components that cannot be in direct contact with the fragrance. For example, a groove can be formed inside the loading member 422, and the component can be installed in the groove. In this way, the components required for the operation of the fragrance device 100 can be installed using the loading member 422, and at the same time, it can be ensured that the components installed in the loading member 422 will not be damaged by the fragrance.

[0159] Please refer to Figure 2 and Figure 3 , in some embodiments, the circuit board 50 is installed on the loading member 422.

[0160] Specifically, the fragrance has a certain corrosiveness. If the circuit board 50 is directly connected to the fragrance, the circuit board 50 may be damaged. Therefore, the loading member 422 can be installed at one end of the seal 421 facing away from the accommodating member 10, and the circuit board 50 can be installed on the loading member 422, such as directly welded to the surface of the loading member 422 or installed inside the loading member 422.

[0161] In this way, while ensuring that the circuit board 50 can control the heating element 20 to heat, the safety of the circuit board 50 can be improved, so as to ensure that the circuit board 50 can operate normally, enabling the heating element 20 to continuously heat the fragrance during the operation of the fragrance device 100.

[0162] Please refer to Figure 2 and Figure 3 , in some embodiments, at least a part of the loading member 422 is inserted into the first opening 412.

[0163] Specifically, the loading member 422 can be connected to one end of the cylinder body 41 close to the cover assembly 42. The connection method can be a detachable connection method and a non-detachable connection method. The detachable connection methods include threaded connection, snap connection, and hinge connection. The non-detachable connection methods include hemming connection, riveting connection, bonding connection, and welding connection, etc. In this way, after the loading member 422 is connected to one end of the cylinder body 41 close to the cover assembly 42, at least part of the loading member 422 is inserted into the first opening 412 to complete the connection between the loading member 422 and the cylinder body 41. At the same time, it is also convenient to fix the loading member 422 by using the cylinder body 41 to prevent the loading member 422 from shaking during use, which may cause the circuit board 50 and the heating member 20 connected to the circuit board 50 to shake, thereby ensuring better heating effect of the heating member 20.

[0164] Please refer to Figure 2 and Figure 3 , in some embodiments, the loading member 422 includes a first cover plate 4221 and a first engaging member 4222 disposed around the first cover plate 4221. A second engaging member 413 is disposed on the cylinder body 41 near the first opening 412. The first engaging member 4222 and the second engaging member 413 are engaged to insert at least part of the loading member 422 into the first opening 412.

[0165] Specifically, the loading member 422 includes a first cover plate 4221 and a first engaging member 4222 disposed around the first cover plate 4221. The first cover plate 4221 is mainly used to load the circuit board 50, and the first engaging member 4222 is mainly used to connect with other components. A second engaging member 413 corresponding to the first engaging member 4222 is disposed on the inner wall of the cylinder body 41 near the first opening 412. Among them, one of the first engaging member 4222 and the second engaging member 413 is a protrusion, and the other is a groove, so that the first engaging member 4222 and the second engaging member 413 can be engaged to insert at least part of the loading member 422 into the first opening 412. The number of the first engaging member 4222 and the second engaging member 413 can be one or more, such as one, two, four, or eight. When both the first engaging member 4222 and the second engaging member 413 are multiple, the number of the first engaging member 4222 and the second engaging member 413 is the same and they correspond one by one. For example, if the first cover plate 4221 is rectangular, the first engaging member 4222 can be disposed at the four corners of the first cover plate 4221. At this time, the number of the first engaging member 4222 is four, and the number of the corresponding second engaging member 413 is also four. In this way, the connection stability between the loading member 422 and the cylinder body 41 can be improved by multiple first engaging members 4222 and second engaging members 413.

[0166] Thus, the loading member 422 can be divided into two parts, namely a first cover plate 4221 and a first engaging member 4222. The first cover plate 4221 is used to realize the function of loading the circuit board 50, and the first engaging member 4222 is used to realize the connection function of the loading member 422, so as to ensure that the loading member 422 can be smoothly installed, and after the installation is completed, the circuit board 50 can supply power to the heating member 20.

[0167] In addition, the cylinder body 41 and the loading member 422 are connected by engaging, which can facilitate the installation of the cylinder body 41 and the loading member 422. At the same time, when it is necessary to repair or replace some components of the fragrance device 100, the connection relationship between the cylinder body 41 and the loading member 422 can be released, and some components of the fragrance device 100 can be repaired or replaced.

[0168] Please refer to Figure 2 and Figure 3 , in some embodiments, the loading member 422 is provided with an installation groove 4223, and the circuit board 50 is arranged in the installation groove 4223. For example, the circuit board 50 can be fixed in the installation groove 4223 by fasteners such as screws and nuts, or the circuit board 50 can be directly placed into the installation groove 4223, and an additional component is connected to the surface of the loading member 422 corresponding to the notch of the installation groove 4223, so that the circuit board 50 is located between the installation groove 4223 and the component, thereby completing the fixation of the circuit board 50.

[0169] Thus, the installation groove 4223 provides a stable support platform for the circuit board 50. Fixing the circuit board 50 in the installation groove 4223 by fasteners such as screws and nuts can significantly enhance the stability and reliability of the circuit board 50, and prevent it from shifting or being damaged due to vibration or external force during use.

[0170] Please refer to Figure 2 and Figure 3 , in some embodiments, a second installation hole 4224 is formed in the bottom wall of the installation groove 4223, and the heating member 20 extends into the accommodating cavity 11 through the second installation hole 4224.

[0171] Specifically, a second installation hole 4224 is formed in the bottom wall of the installation groove 4223, and the size of the second installation hole 4224 is determined according to the size of the heating member 20 to ensure that the heating member 20 can pass through the second installation hole 4224. The heating member 20 can extend towards the accommodating member 10 through the second installation hole 4224, so that the extended part of the heating member 20 can sequentially pass through the second installation hole 4224 and the first installation hole 4213 of the sealing plate 4211, and then extend into the accommodating cavity 11 through the second opening 12, so as to ensure that the heating member 20 can heat the fragrance adsorbed by the adsorbing member 30 in the accommodating cavity 11.

[0172] In this way, the circuit board 50 can be installed by opening an installation groove 4223 in the loading member 422, and the installation groove 4223 is provided with a second installation hole 4224 for the heating member 20 to pass through. Thus, on the one hand, it is ensured that after the circuit board 50 is installed, the circuit board 50 can be protected by the sealing member 421, and on the other hand, it is ensured that the heating member 20 can extend into the accommodating member 10 through the second installation hole 4224 to heat the fragrance.

[0173] Please refer to Figure 2 and Figure 3 , in some embodiments, the cover assembly 42 further includes a cover body 423, and the cover body 423 is disposed on the loading member 422, and the loading member 422 is located between the sealing member 421 and the cover body 423.

[0174] Specifically, the cover body 423 is disposed on the loading member 422, and the cover body 423 can be connected to the loading member 422, and the connection method can be a detachable connection method and a non-detachable connection method. The detachable connection methods include screw connection, snap connection and hinge connection, and the non-detachable connection methods include hemming connection, rivet connection, bonding connection and welding connection, etc.

[0175] The loading member 422 is located between the sealing member 421 and the cover body 423, that is, the opposite ends of the loading member 422 are respectively connected to the sealing member 421 and the cover body 423, so that the cover body 423 can block at least part of the area of one end of the loading member 422 facing the outside world to ensure the neatness of the appearance of the fragrance device 100 and improve the aesthetics of the fragrance device 100. At the same time, the setting of the cover body 423 can further improve the safety of the circuit board 50 in the loading member 422.

[0176] In one embodiment, the fragrance device 100 is provided with a power supply assembly, and the power supply assembly is connected to the heating member 20 to supply electric energy to the heating member 20. The power supply assembly is located in the cover assembly 42 and is connected to the heating member 20 to supply power to the heating member 20 by using the power supply assembly to ensure that the heating member 20 can be heated. At this time, the cover body 423 can completely block one end of the loading member 422 facing the outside world to further increase the protection effect of the cover body 423.

[0177] In another embodiment, please combine Figure 5, the power supply component 200 is a component outside the aroma device 100. At this time, a perforation 42311 can be provided on the cover body 423. The cover body 423 can block a part of the area at one end of the loading member 422 facing the outside. At this time, the cover body 423 can also specifically block a part of the area at one end of the loading member 422 facing the outside that affects the aesthetics of the aroma device 100, so as to ensure the cleanliness of the appearance of the aroma device 100 on the one hand, and ensure that the heating element 20 can be connected to the external power supply component 200 through the perforation 42311 and be powered on on the other hand. At the same time, the setting of the cover body 423 can further prevent the heating element 20 installed on the loading member 422 from being damaged by the outside.

[0178] In this way, the cover body assembly 42 can further improve the safety of the heating element 20 by setting the cover body 423. At the same time, the cover body 423 can also block at least a part of the area at the end of the loading member 422 facing away from the accommodating member 10, so as to ensure the cleanliness of the appearance of the aroma device 100 and improve the aesthetics of the aroma device 100.

[0179] Please refer to Figure 2 and Figure 3 , in some embodiments, the cover body 423 includes a second cover plate 4231 and a side plate 4232 arranged around the second cover plate 4231. The second cover plate 4231 is used to at least partially seal the mounting groove 4223 to protect the circuit board 50 in the mounting groove 4223, and the side plate 4232 is connected to the loading member 422.

[0180] Specifically, the side plate 4232 can be connected to the edge of the second cover plate 4231 and extend in a direction away from the second cover plate 4231, so that after the side plate 4232 and the second cover plate 4231 are connected, the cover body 423 as a whole presents a bowl shape. At the same time, the side plate 4232 can be connected to the loading member 422, and the connection methods can all be detachable connection methods and non-detachable connection methods. The detachable connection methods include threaded connection, snap connection and hinge connection, and the non-detachable connection methods include hemming connection, riveting connection, bonding connection and welding connection, etc. In the case where the side plate 4232 is connected to the loading member 422, it can be considered that the cover body 423 is buckled on the loading member 422. At this time, the second cover plate 4231 connected to the side plate 4232 can block at least a part of the area at one end of the loading member 422 facing the outside.

[0181] For example, in some embodiments, the side plate 4232 is provided with a third engaging member, and the loading member 422 is provided with a fourth engaging member 4225, and the third engaging member and the fourth engaging member 4225 are engaged. For example, the inner wall of the side plate 4232 is provided with a third engaging member, and the surface of the loading member 422 opposite to the inner wall of the side plate 4232 is provided with a fourth engaging member 4225.

[0182] Wherein, one of the third engaging member and the fourth engaging member 4225 is a protrusion and the other is a groove, so that the third engaging member and the fourth engaging member 4225 can be engaged to realize the connection between the side plate 4232 and the loading member 422. The number of the third engaging member and the fourth engaging member 4225 can be one or more, such as one, two, four or eight. When both the third engaging member and the fourth engaging member 4225 are multiple, the number of the third engaging member and the fourth engaging member 4225 is the same and they correspond to each other one by one. In this way, the connection between the side plate 4232 and the loading member 422 can be realized in a form of engagement. At the same time, when both the third engaging member and the fourth engaging member 4225 are multiple, the multiple third engaging members and fourth engaging members 4225 can improve the connection stability between the loading member 422 and the cylinder body 41.

[0183] Wherein, the second cover plate 4231 is used to at least partially seal the installation groove 4223, that is, along the normal direction of the second cover plate 4231, the orthographic projection of the second cover plate 4231 on the loading member 422 is at least partially located within the contour of the installation groove 4223, so as to at least partially block the side of the circuit board 50 in the installation groove 4223 facing the outside world, thereby protecting the circuit board 50 in the installation groove 4223.

[0184] In this way, the cover body 423 can be divided into two regions, one is the second cover plate 4231 and the other is the side plate 4232. The side plate 4232 is mainly used to connect with the loading member 422, and the second cover plate 4231 can be used to block at least part of the region at one end of the installation groove 4223 facing the outside world, so as to facilitate the installation of the cover body 423 and realize the shielding function of the cover body 423 at the same time.

[0185] Please refer to Figure 2 and Figure 3 In some embodiments, the second cover plate 4231 is provided with a perforation 42311, and the perforation 42311 and the circuit board 50 are arranged opposite to each other. The perforation 42311 is used to allow the circuit board 50 to be connected to the outside.

[0186] Specifically, the circuit board 50 needs to be connected to an external power supply component to obtain electric energy. Therefore, a perforation 42311 can be provided on the second cover plate 4231, and the perforation 42311 and the circuit board 50 are arranged opposite to each other. The perforation 42311 is communicated with the installation groove 4223, so that an external power supply component can pass through the second cover plate 4231 through the perforation 42311 and be connected to the circuit board 50, so as to ensure that the circuit board 50 can be connected to the outside and obtain electric energy on the premise that the circuit board 50 can be protected by the second cover plate 4231.

[0187] Please refer to Figure 2 and Figure 3, in some embodiments, the circuit board 50 includes a soldering portion 51, and the soldering portion 51 is located outside the contour of the orthographic projection of the through hole 42311 on the circuit board 50, so that the second cover plate 4231 shields the soldering portion 51 of the circuit board 50

[0188] Specifically, after the circuit board 50 is installed on the loading member 422, at least part of the circuit board 50 is exposed to the outside. The heating member 20 is connected to the soldering portion 51 of the circuit board 50. It can be understood that the soldering point of the heating member 20 is located on the soldering portion 51. If the soldering point is damaged by the outside, the normal operation of the heating member 20 will be affected. At the same time, in order to prevent the loading member 422 itself from wearing the soldering point, the soldering portion 51 is generally arranged on the side of the circuit board 50 facing the outside. Therefore, the second cover plate 4231 needs to shield the soldering portion 51 so that the soldering portion 51 is not exposed to the outside.

[0189] The soldering portion 51 being located outside the orthographic projection of the through hole 42311 on the circuit board 50 means that in the normal direction of the second cover plate 4231, the soldering portion 51 is located in the projection of the through hole 42311 on the circuit board 50. According to the position of the soldering portion 51 on the circuit board 50, the position of the through hole 42311 is set so that the soldering portion 51 is located outside the contour of the orthographic projection of the through hole 42311 on the circuit board 50. It can be understood that the area covered by the orthographic projection of the second cover plate 4231 on the circuit board 50 is the area of the circuit board 50 shielded by the second cover plate 4231. In this way, it can be ensured that the soldering portion 51 is shielded by the area of the second cover plate 4231 other than the through hole 42311.

[0190] For example, the centers of the circuit board 50 and the second cover plate 4231 can be aligned, the distance between the center of the circuit board 50 and the soldering portion 51 of the circuit board 50 is obtained, and the radius of the through hole 42311 is determined according to the distance between the center of the circuit board 50 and the soldering portion 51 of the circuit board 50. The radius is at least less than or equal to the distance between the center of the circuit board 50 and the soldering portion 51 of the circuit board 50. Then, with the center of the second cover plate 4231 as the center of the circle, the determined distance is used as the radius to set the through hole 42311.

[0191] In this way, it can be ensured that there is no soldering portion 51 of the circuit board 50 in the area where the loading member 422 is exposed to the outside from the through hole 42311, so as to shield the soldering point of the heating member 20 on the soldering portion 51, thus ensuring the cleanliness of the appearance of the fragrance device 100 and preventing the hidden danger of damage to the heating circuit caused by the exposure of the soldering point to the outside.

[0192] Please refer to Figure 1 and Figure 2 , in some embodiments, the fragrance device 100 further includes a decorative member 60, and the decorative member 60 is installed on the housing 40.

[0193] Specifically, the fragrance device 100 may further be provided with a decorative member 60. The number of the decorative members 60 may be one or more, such as one, two, or four, and is specifically set according to needs. The decorative member 60 may be installed on the housing 40, such as in the middle or at the top of the housing 40, so as to facilitate improving the aesthetics of the fragrance device 100.

[0194] Please refer to Figure 1 and Figure 2 , in some embodiments, the decorative member 60 is connected to one end of the barrel 41 of the housing 40 that is away from the cover assembly 42 of the housing 40.

[0195] Specifically, the cover assembly 42 is connected to one end of the barrel 41, and the decorative member 60 is connected to the end of the barrel 41 that is away from the cover assembly 42. The connection method may be a detachable connection method and a non-detachable connection method. The detachable connection methods include threaded connection, snap connection, and hinge connection. The non-detachable connection methods include hemming connection, riveting connection, bonding connection, and welding connection, etc.

[0196] The decorative member 60 is disposed at the end of the barrel 41 that is away from the cover assembly 42, which can ensure that the decorative member 60 does not affect the installation and operation of the heating element 20 installed on the cover assembly 42, and at the same time, the decorative member 60 can be used to improve the aesthetics of the fragrance device 100.

[0197] In this way, the fragrance device 100 can be provided with the decorative member 60 without affecting the operation of each component in the fragrance device 100, so as to ensure that the fragrance device 100 can efficiently disperse fragrance on the one hand, and improve the aesthetics of the fragrance device 100 on the other hand.

[0198] Please refer to Figure 1 and Figure 2 , in some embodiments, the decorative member 60 includes a first decorative member 61, and the first decorative member 61 is connected to the end of the barrel 41 that is away from the cover assembly 42.

[0199] Specifically, the connection method between the first decorative member 61 and the end of the barrel 41 that is away from the cover assembly 42 may be a detachable connection method and a non-detachable connection method. The detachable connection methods include threaded connection, snap connection, and hinge connection. The non-detachable connection methods include hemming connection, riveting connection, bonding connection, and welding connection, etc.

[0200] In this way, the fragrance device 100 can be provided with the first decorative member 61 without affecting the operation of each component in the fragrance device 100, so as to ensure that the fragrance device 100 can efficiently disperse fragrance on the one hand, and improve the aesthetics of the fragrance device 100 on the other hand.

[0201] In some embodiments, the first decorative member 61 includes a fixing groove 611, and the barrel 41 includes a third boss 414. The third boss 414 is embedded in the fixing groove 611, thereby connecting the first decorative member 61 and the barrel 41.

[0202] Specifically, the fixing groove 611 can be formed inside the first decorative member 61, and one end of the barrel 41 facing away from the cover assembly 42 can extend in a direction away from the cover assembly 42 to form the third boss 414. The shapes and sizes of the third boss 414 and the fixing groove 611 match, so that the third boss 414 can be embedded in the fixing groove 611, thereby realizing the connection between the first decorative member 61 and the barrel 41.

[0203] For example, the fixing groove 611 is provided with a fifth engaging member 6111, and the third boss 414 is provided with a sixth engaging member 4141. The fifth engaging member 6111 and the sixth engaging member 4141 are engaged. Among them, one of the fifth engaging member 6111 and the sixth engaging member 4141 is a protrusion, and the other is a groove, so that the fifth engaging member 6111 and the sixth engaging member 4141 can be engaged to realize the connection between the first decorative member 61 and the barrel 41. The number of the fifth engaging member 6111 and the sixth engaging member 4141 can be one or more, such as one, two, four or eight. In this way, the connection between the first decorative member 61 and the barrel 41 can be realized in a snap-fit manner. At the same time, when both the fifth engaging member 6111 and the sixth engaging member 4141 are multiple, the multiple fifth engaging members 6111 and sixth engaging members 4141 can improve the connection stability between the first decorative member 61 and the barrel 41.

[0204] In some other embodiments, it can be achieved only by relying on the third boss 414 and the fixing groove 611. At this time, an interference fit can be provided between the third boss 414 and the fixing groove 611, so as to ensure that the third boss 414 will not easily disengage from the fixing groove 611 after being installed in the fixing groove 611.

[0205] In this way, the first decorative member 61 and the barrel 41 can be stably connected by using the third boss 414 and the fixing groove 611, so as to ensure that the first decorative member 61 will not easily fall off during the use of the fragrance device 100.

[0206] Please refer to Figure 1 and Figure 2 , in some embodiments, the decorative member 60 further includes a second decorative member 62, and the second decorative member 62 is disposed on a side of the first decorative member 61 facing away from the barrel 41.

[0207] Specifically, there can be two decorative members 60, namely the first decorative member 61 and the second decorative member 62. The first decorative member 61 is connected to one end of the barrel 41 facing away from the cover assembly 42, and the second decorative member 62 is disposed on a side of the first decorative member 61 facing away from the barrel 41.

[0208] Among them, the connection manner between the first decorative member 61 and the second decorative member 62 can be a detachable connection manner and a non-detachable connection manner.
