[0065] The embodiments of this application are described in detail below. Examples of the 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 the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0066] With the rapid development of my country's economy, consumers have increasingly higher demands for the driving environment. In-car fragrance devices, which improve the in-car environment by actively or passively providing fragrance in conjunction with the vehicle's infotainment system to create a comfortable driving atmosphere, have attracted significant attention from consumers. Therefore, improving the effectiveness of fragrance devices in creating a pleasant aroma has become a pressing issue.

[0067] Most existing car fragrance devices use a single carrier infused with fragrance as the primary source of scent diffusion. After prolonged use, the fragrance fades, and the consistency of the scent throughout its lifespan cannot be controlled. Frequent replacement of the fragrance bottle is necessary to maintain a high-quality fragrance experience, which may reduce user satisfaction and lead to poor market feedback. Furthermore, most current fragrance blocks rely on natural diffusion, which cannot quickly create a fragrant atmosphere.

[0068] To address the above problems, embodiments of this application provide a fragrance device 100 and a vehicle 1000, which will be described in detail below:

[0069] Please refer to Figures 1 to 3. This application provides a fragrance device 100, which includes a receiving member 10 and a heating member 20. The receiving member 10 forms a receiving cavity 11 for containing fragrance. The heating member 20 is used to heat the fragrance to generate aroma.

[0070] Specifically, the fragrance device 100 is a device that can create a specific atmosphere using volatile substances with fragrance. The fragrance device 100 includes a housing 10 and a heating element 20.

[0071] The accommodating member 10 has a hollow internal structure to form a accommodating cavity 11. For example, the accommodating member 10 includes a bottom wall 13 and an annular sidewall 14. The annular sidewall 14 is disposed on the bottom wall 13 and extends along the edge of the bottom wall 13 to form a tube, thereby making the accommodating member 10 cup-shaped. The annular sidewall 14 and the bottom wall 13 together form the accommodating cavity 11. The accommodating cavity 11 is used to contain a fragrance, wherein the fragrance is a product containing essential oils, fixatives (which may be chemical or natural ingredients), and other possible additives, which can produce a fragrance upon evaporation. The fragrance can be a liquid fragrance or a solid fragrance. A liquid fragrance is a liquid product containing essential oils, fixatives (which may be chemical or natural ingredients), and other possible additives. A solid fragrance is a solid product composed of a liquid fragrance and a solid medium. Both liquid and solid fragrances can evaporate into a fragrance. Furthermore, solid fragrances encompass liquid fragrances and other non-volatile substances; only liquid fragrances can evaporate into aroma and create a scented atmosphere. Therefore, compared to storing solid fragrances in the receiving cavity 11, storing liquid fragrances in the receiving cavity 11 allows for a larger volume of liquid fragrance, resulting in a longer lifespan when using liquid fragrances compared to solid fragrances. Therefore, preferably, the fragrance of this application is a liquid fragrance.

[0072] 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 common type of heating element. It heats up after being energized, converting electrical energy into heat energy to achieve the desired heating effect. For example, the material of the heating element 20 can be tin-plated copper wire. The heating element 20 can heat fragrance. For example, the heating element 20 can extend into the receiving cavity 11, so that at least a portion of the heating element 20 is located within the receiving cavity 11 and in contact with the fragrance to heat it. Alternatively, the heating element 20 can abut against the side wall of the receiving member 10, allowing the heat from the heating element 20 to be transferred through the side wall of the receiving member 10 to the fragrance inside the receiving cavity 11, thereby heating the fragrance. Fragrance itself has a certain degree of volatility; heating increases its evaporation rate, forming a scent. The scent can evaporate to the outside of the fragrance device 100 (i.e., areas outside the fragrance device 100) to create a fragrant atmosphere.

[0073] During the operation of the fragrance device 100, the heating element 20 heats the fragrance in the accommodating cavity 11 to accelerate the evaporation rate of the fragrance, so that the fragrance device 100 can quickly diffuse a large amount of fragrance to the outside in a short time, thereby improving the effect of the fragrance atmosphere created by the fragrance device 100 and increasing user satisfaction with the fragrance device 100.

[0074] The fragrance device 100 of this embodiment includes a receiving member 10 and a heating member 20. Fragrance is contained in the receiving cavity 11 inside the receiving member 10. The heating member 20 heats the fragrance to generate aroma. Therefore, during operation of the fragrance device 100, the heating member 20 heats the fragrance to accelerate its evaporation, enabling the fragrance device 100 to rapidly diffuse a large amount of fragrance into the environment in a short time, achieving more efficient fragrance dissipation. This improves the fragrance atmosphere created by the fragrance device 100 and increases user satisfaction with the fragrance device 100.

[0075] Referring to Figures 2 and 3, in some embodiments, the container 10 is made of a porous material, such as porous ceramic, resulting in multiple vent holes on the container 10. The vent holes have a small diameter, allowing aroma to pass through. The vent holes are distributed throughout the container 10, enabling the aroma to diffuse to the outside through various areas of the container 10, thereby improving the uniformity of aroma diffusion.

[0076] Specifically, when the fragrance is a liquid fragrance, the vent allows the fragrance to slowly permeate to the outside. The permeation rate can be controlled by adjusting the size of the vent, ensuring that the fragrance only permeates slowly to the outside without significant leakage. The fragrance within the container 10 can slowly permeate to the outside of the container 10 through the vent and evaporate, achieving natural fragrance diffusion. Building upon the natural fragrance diffusion achieved by the container 10, the heating element 20 can further accelerate the evaporation of the fragrance within the container cavity 11 to generate aroma. This aroma can then diffuse to the outside of the container 10 through the vent, creating a fragrant atmosphere. Thus, with the natural fragrance diffusion of the container 10 and the accelerated evaporation by the heating element 20, this application can create a fragrant atmosphere more quickly.

[0077] Referring to Figures 2 and 3, in some embodiments, the container 10 can also be made of a material with good sealing properties, such as glass. In this case, the container 10 also has a vent that communicates with the outside, for example, a vent can be provided at the top of the container 10 exposed to the outside. For instance, if the container 10 is a glass bottle, a bottle opening (i.e., a vent) can be provided at the top of the glass bottle. The fragrance near the vent can naturally evaporate, and the naturally evaporated fragrance can flow to the outside through the vent. Simultaneously, the gaseous fragrance generated by the heating element 20 after heating the fragrance can also flow to the outside through the vent. Thus, the container 10 can also achieve natural fragrance diffusion, and the gaseous fragrance generated by the heating element 20 after heating can also be diffused to the outside, thereby enabling this application to create a fragrant atmosphere more quickly.

[0078] Please refer to Figures 2 to 4. In some embodiments, the fragrance device 100 further includes an adsorption element 30 located within the receiving cavity 11, which is used to adsorb fragrance.

[0079] Specifically, when the fragrance is a liquid fragrance, an absorbent element 30 can be used to absorb the liquid fragrance. The absorbent element 30 is a component with the ability to absorb liquids, such as felt or absorbent cotton. The absorbent element 30 can be made of materials that are heat-resistant, have high oil absorption efficiency, and are corrosion-resistant, such as felt. Heat resistance prevents the absorbent element 30 from burning due to high temperatures caused by a short circuit in the heating element 20, ensuring the safety of the fragrance device 100. High oil absorption efficiency ensures that the absorbent element 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 absorbent element 30 also needs to be corrosion-resistant.

[0080] The adsorbent 30 is disposed in the accommodating cavity 11 to continuously adsorb fragrance, thereby facilitating the heating element 20 to continuously heat the fragrance adsorbed by the adsorbent 30.

[0081] Referring to Figures 2 to 4, in some embodiments, the adsorption element 30 includes a first adsorption strip 31 and two second adsorption strips 32. Both the first adsorption strip 31 and the second adsorption strip 32 are strip-shaped to facilitate the absorption of fragrance. The two ends of the first adsorption strip 31 are respectively connected to one end of each of the two second adsorption strips 32. This can be understood as the adsorption element 30 having an overall U-shape. This increases the space occupied by the adsorption element 30 within the accommodating cavity 11, increasing the adsorption area of ​​the adsorption element 30 and thus enhancing its adsorption effect. This ensures that the heating element 20 always has sufficient fragrance for heating, thereby ensuring the heating effect of the heating element 20.

[0082] Please refer to Figures 2 to 4. In some embodiments, the receiving member 10 is cup-shaped and includes a bottom wall 13 and an annular side wall 14. The annular side wall 14 is disposed on the bottom wall 13. The bottom wall 13 and the annular side wall 14 together form a receiving cavity 11. The first adsorption strip 31 is disposed parallel to the bottom wall 13, and the second adsorption strip 32 is disposed parallel to the annular side wall 14.

[0083] Specifically, the first adsorption strip 31 is arranged parallel to the bottom wall 13, and the second adsorption strip 32 is arranged parallel to the annular side wall 14. That is, the first adsorption strip 31 is arranged along the extension direction of the bottom wall 13, and the second adsorption strip 32 is arranged along the extension direction of the annular side wall 14, so that the shape of the adsorption member 30 matches the shape of the accommodating cavity 11. Thus, the first adsorption strip 31 and the second adsorption strip 32 are smoothly installed into the accommodating cavity 11, and the first adsorption strip 31 and the second adsorption strip 32 occupy a large space in the accommodating cavity 11, which can adsorb fragrance in different areas of the accommodating cavity 11.

[0084] At this time, the first adsorption strip 31 can be set along the edge of the bottom wall 13, and the second adsorption strip 32 can be set along the edge of the annular sidewall 14. That is, the first adsorption strip 31 is set in the area of ​​the accommodating cavity 11 near the bottom wall 13, and the second adsorption strip 32 is set in the area of ​​the accommodating cavity 11 near the annular sidewall 14, so that the first adsorption strip 31 is set parallel to the bottom wall 13, and the second adsorption strip 32 is set parallel to the annular sidewall 14. The adsorption element 30 can be set along the edges of the accommodating cavity 11 at three positions, thereby ensuring that the adsorption element 30 can fully absorb the fragrance in the accommodating cavity 11. At the same time, the adsorption element 30 is set around the edge of the accommodating cavity 11, so that the fragrance generated after being heated by the heating element 20 can quickly move to the edge of the accommodating cavity 11, thereby quickly diffusing to the outside of the fragrance device 100.

[0085] Referring to Figures 1 and 4, in some embodiments, the heating element 20 includes a first heating wire 21 and two second heating wires 22. In this case, the heating element 20 is a heating wire with good formability, making it easy to process 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. The two ends of the first heating wire 21 are respectively connected to one end of each of the two second heating wires 22, that is, the area of ​​the heating element 20 located in the receiving cavity 11 also presents a U-shape. In this way, the heating area of ​​the heating element 20 in the receiving cavity 11 can be expanded, thereby ensuring the heating effect of the heating element 20, and at the same time, making the shape of the heating element 20 match that of the adsorbent 30, so as to improve the heating effect of the heating element 20 on the fragrance adsorbed by the adsorbent 30.

[0086] The accommodating member 10 has at least one end with a first opening 412, so that the heating member 20 can be inserted into the accommodating cavity 11. At this time, the positional relationship between the heating member 20 and the adsorption member 30 can be various.

[0087] In one embodiment, the heating element 20 is disposed close to the adsorbent 30, i.e., near the adsorbent 30, so that the heating element 20 can heat the fragrance adsorbed by the adsorbent 30. In another embodiment, the heating element 20 at least partially surrounds the adsorbent 30. For example, the heating element 20 only surrounds the adsorbent 30, in which case all or part of the heating element 20 is disposed around the adsorbent 30. Another example is that the heating element 20 is only close to the adsorbent 30, in which case all or part of the heating element 20 is close to the adsorbent 30. Yet another example is that some of the heating elements 20 are close to the adsorbent 30, and the remaining portion of the heating elements 20 surrounds the adsorbent 30. Alternatively, some of the heating elements 20 are close to the adsorbent 30, some are surrounding the adsorbent 30, and some are neither surrounding nor close to the adsorbent 30.

[0088] Thus, during the operation of the fragrance device 100, the adsorption element 30 continuously adsorbs fragrance, and the heating element 20 heats the fragrance adsorbed by the adsorption element 30 to accelerate its evaporation. Simultaneously, the amount of fragrance stored in the adsorption element 30 is relatively stable, therefore the amount of fragrance heated by the heating element 20 during the heating process is also relatively stable. This results in a relatively stable volume of fragrance generated and volatilized during the operation of the fragrance device 100, allowing the fragrance device 100 to maintain fragrance stability over a long period. This, in turn, enhances the fragrance atmosphere created by the fragrance device 100 and increases user satisfaction with the fragrance device 100.

[0089] Please refer to Figure 4. In some embodiments, the first heating wire 21 is arranged around the first adsorption strip 31.

[0090] 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 evenly transferred to the first adsorption strip 31 and the second heating wires 22 on both sides of the first heating wire 21. This ensures that the heating effect is the same on both sides of the heating element 20 when the fragrance device 100 is divided into two sides with the first heating wire 21 as the center, resulting in the same fragrance diffusion effect on both sides and thus improving the user experience. At the same time, since the first heating wire 21 is spiral-shaped, the resistance of the first heating wire 21 is relatively large, and in this case, the first heating wire 21 can be regarded as the resistance of the heating element 20.

[0091] 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 resistance can be used to heat the fragrance, so as to increase the amount of fragrance produced, and enable the fragrance device 100 to produce a large amount of fragrance in a short time, thereby facilitating the fragrance device 100 to achieve efficient fragrance dispersal.

[0092] Referring to Figures 2 and 4, in some embodiments, the second heating wire 22 is positioned 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 sidewall 14, and the distance between the second adsorption strip 32 and the second heating wire 22 is less than a preset distance threshold. In this case, the second heating wire 22 is positioned parallel to the corresponding second adsorption strip 32, which ensures 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 is also wrapped around the second adsorption strip 32, the length of the second heating wire 22 will be longer than the length of the horizontally positioned second heating wire 22. Therefore, the second heating wire 22 is not wrapped around the second adsorption strip 32, but is installed close to the second adsorption strip 32, which on the one hand ensures that the second heating wire 22 can effectively heat the fragrance adsorbed in the second adsorption strip 32, and on the other hand reduces the manufacturing cost of the second heating wire 22.

[0093] In this way, the second heating wire 22 can effectively heat the fragrance in the second adsorption strip 32, so as to increase the amount of fragrance produced, and enable the fragrance device 100 to produce a large amount of fragrance in a short time, thereby facilitating the fragrance device 100 to achieve efficient fragrance dispersal.

[0094] Please refer to Figure 4. In some embodiments, the distance between the first heating wire 21 and the second heating wire 22 and the adsorption member 30 is less than a preset distance threshold.

[0095] Specifically, the preset distance threshold is the minimum distance between the adsorbent 30 and the heating element 20 when the heating element 20 can efficiently heat the fragrance adsorbed by the adsorbent 30, for example, 2 mm. Whether the heating element 20 surrounds the adsorbent 30 or is positioned close to the adsorbent 30, the distance between them can be less than the preset distance threshold. Therefore, the distance between the first heating wire 21 and the adsorbent 30 is less than the preset distance threshold, and the distance between the second heating wire 22 and the adsorbent 30 is also less than the preset distance threshold. This ensures that both the first heating wire 21 and the second heating wire 22 can efficiently heat the corresponding areas of the adsorbent 30.

[0096] In summary, the heating element 20 can heat the fragrance adsorbed in various areas of the adsorption element 30. Even when the fragrance level inside the receiving cavity 11 decreases, the adsorption element 30 can still adsorb the fragrance. Furthermore, in areas of the adsorption element 30 that adsorb a large amount of fragrance, the adsorbed fragrance will move to areas that adsorb less fragrance, thus ensuring a relatively stable amount of fragrance adsorbed in each area of ​​the adsorption element 30. Therefore, during the use of the fragrance device 100, even if the fragrance level decreases, the amount of fragrance heated by the heating element 20 remains relatively stable, and the amount of fragrance produced after heating also remains relatively stable, thereby ensuring that the fragrance device 100 can maintain fragrance stability over a long period.

[0097] Please refer to Figure 2. When the fragrance is a solid fragrance, the positional relationship between the heating element 20 and the fragrance can be varied.

[0098] In some embodiments, the heating element 20 is placed close to the fragrance setting, such as against the fragrance, or installed near the fragrance, so that the heat emitted by the heating element 20 can be transferred to the fragrance and heat the fragrance, thereby ensuring a high evaporation rate of the fragrance.

[0099] In other embodiments, the heating element 20 is inserted into the fragrance, that is, the heating element 20 extends into the fragrance to increase the contact area between the heating element 20 and the fragrance, so that the heat generated by the heating element 20 can be directly transferred to the fragrance and heated, thereby reducing heat loss and improving heat utilization and the evaporation rate of the fragrance.

[0100] Referring to Figure 2, in some embodiments, the fragrance device 100 includes a temperature sensor (not shown) for detecting the current temperature of the heating element 20.

[0101] Specifically, the fragrance device 100 is equipped with a temperature sensor, which can be located 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 status of the heating element 20 based on the current temperature detected by the temperature sensor, and to control the heating element 20 to start and stop heating based on the current heating status of the heating element 20.

[0102] Referring to Figure 2, in some embodiments, the fragrance device 100 includes a circuit board 50 connected to a heating element 20. A temperature sensor is disposed on the circuit board 50, which controls the heating element 20 to heat or stop heating based on the current temperature and a preset temperature range, so that the temperature of the heating element 20 is within the preset temperature range.

[0103] Specifically, the higher the temperature of the heating element 20, the faster the fragrance evaporates. If the fragrance evaporates too slowly, it will affect the fragrance emission rate of the fragrance device 100. If the fragrance evaporates too quickly, it may cause the fragrance emitted by the fragrance device 100 to be too strong, thus affecting the user experience. Therefore, a preset temperature range can be set for the temperature of the heating element 20 when the fragrance emission concentration is optimal, for example, a preset temperature range of [35℃, 45℃].

[0104] The circuit board 50 is connected to the heating element 20. 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 element 20 to heat or stop heating.

[0105] In some embodiments, the circuit board 50 may be a physical circuit board 50, on which multiple components are provided. The circuit board 50 can supply power to the heating element 20, causing the heating element 20 to generate heat when powered on. In some embodiments, the circuit board 50 has a control function, which can directly control whether the heating element 20 is heated by controlling whether power is supplied to it. Alternatively, in other embodiments, the circuit board 50 can only be used for supplying power and does not have a control function. In this case, the fragrance device 100 may also be provided with a corresponding control device. The control device can control whether the heating element 20 is heated by controlling whether power is supplied to the circuit board 50. That is, the control device can control the heating element 20 by means of the circuit board 50.

[0106] The circuit board 50 can control the heating element 20 to heat or stop heating based on the current temperature and a preset temperature range, so that the temperature of the heating element 20 remains within the preset temperature range. First, the stop heating temperature can be determined based on the preset temperature range. The stop heating temperature is the temperature of the heating element 20 when heating needs to be stopped. The stop heating temperature can be any temperature within the preset temperature range, such as the highest temperature, lowest temperature, or midpoint of the preset temperature range, depending on the requirements of each heating process. For example, if the preset temperature range is [35℃, 45℃], then the stop heating temperature can be 35℃, 40℃, or 45℃. If the stop heating temperature is the maximum temperature within the preset temperature range, it ensures that the fragrance evaporation rate meets requirements and delays the rate at which the current temperature of the heating element 20 drops below the minimum temperature within the preset temperature range after heating is stopped.

[0107] If the current temperature of the heating element 20 is lower than the minimum value of the preset temperature range, the heating element 20 heats up to raise its current temperature to the preset temperature range until it reaches the stop heating temperature. Once the current temperature of the heating element 20 reaches the stop heating temperature, the heating element 20 stops heating to prevent overheating.

[0108] In this way, the temperature of the heating element 20 can be maintained within the preset temperature range as much as possible, thereby ensuring that the fragrance is emitted at a better concentration.

[0109] Please refer to Figure 2. In some embodiments, the heating of the heating element 20 includes a temperature rise phase.

[0110] Specifically, the heating phase is the stage where the heating element 20 heats up from its initial temperature when the fragrance device 100 is activated to within a preset temperature range. During this phase, the heating element 20 begins heating, and its temperature gradually rises until it reaches within the preset temperature range, ensuring that the temperature of the heating element 20 remains within this range and thus ensuring rapid fragrance evaporation. The current temperature of the heating element 20 can be obtained from a temperature sensor, allowing for precise determination of the end time of the heating phase.

[0111] Please refer to Figure 2. In some embodiments, the heating of the heating element 20 includes a heat preservation stage.

[0112] Specifically, the heat preservation stage is the stage in which the current temperature of the heating element 20 is maintained within a preset temperature range. During the heat preservation stage, the heating element 20 can heat or stop heating based on its current temperature and the preset temperature range. The heating element 20 heats when its current temperature is lower than the minimum value of the preset temperature range, and stops heating when its current temperature is within the preset temperature range, so that the temperature of the heating element 20 can be maintained within the preset temperature range for as long as possible.

[0113] In some embodiments, the heating element 20 includes a heating phase and a holding phase. The current temperature detected by the temperature sensor can be used to determine whether the heating element 20 is currently in the heating phase or the holding phase. After the fragrance device 100 is activated, the heating element 20 is considered to be in the heating phase. Then, the temperature of the heating element 20 rises from the initial temperature to a preset temperature range. When the current temperature of the heating element 20 is within the preset temperature range, it is considered to have entered the holding phase. At this time, the circuit board 50 can maintain the temperature of the heating element 20 within the preset temperature range according to a corresponding strategy.

[0114] 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 generated corresponding to the preset operating parameters and the heat dissipation of the fragrance corresponding to the preset temperature range is within the preset difference range.

[0115] Specifically, the preset operating parameters are those that affect heat generation, such as a preset heating power. The heat generation of the heating element 20 under different operating parameters can be predetermined. Simultaneously, the heat dissipation of the fragrance when the heating element 20 is within a preset temperature range is predetermined. Then, a preset operating parameter is selected where the difference between the heat generation and the heat dissipation of the fragrance is within a preset difference range, and the heating element 20 is controlled to heat based on the preset operating parameters. The preset difference range is the range of the difference between the heat generation of the heating element 20 and the heat dissipation of the fragrance, meaning they are approximately the same or completely the same, allowing the fragrance temperature to remain stable within a small range. In one embodiment, the preset difference range is [-0.15W, 0.15W]. When the difference between the heat generation 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 generation of the heating element 20 and the heat dissipation of the fragrance are balanced, and the fragrance temperature can be stabilized within a small range. If the difference between the heat generated by the heating element 20 and the heat dissipation of the fragrance is outside the preset difference range, it can be considered that the heat generated by the heating element 20 and the heat dissipation of the fragrance are unbalanced, and the temperature of the fragrance fluctuates greatly.

[0116] After the fragrance device 100 is activated, the heating element 20 can be continuously heated according to preset operating parameters. Since the initial temperature of the heating element 20 is generally lower than the preset temperature range, the heat generated by the heating element 20 is greater than the heat dissipated by the fragrance. The temperature of the heating element 20 gradually rises until it reaches the preset temperature range. When the temperature of the heating element 20 reaches the preset temperature range, the difference between the heat generated by the heating element 20 and the heat dissipated by the fragrance is within a preset difference range, ensuring that the heat generated by the heating element 20 and the heat dissipated by the fragrance are ultimately balanced, thus maintaining the current temperature of the heating element 20 within the preset temperature range. It can be understood that a temperature sensor is not required at this point. Therefore, during the operation of the fragrance device 100, continuously controlling the heating element 20 according to the preset operating parameters ensures that the temperature of the heating element 20 can rise and be maintained within the preset temperature range for a long time.

[0117] In another embodiment, control can be achieved using a temperature sensor. After the fragrance device 100 is activated, it can heat based on the maximum heating power until the current temperature obtained from the temperature sensor is within a preset temperature range, thereby accelerating the heating rate. If the current temperature is within the preset temperature range, the heating element 20 is continuously controlled to heat based on preset operating parameters to maintain the current temperature of the heating element 20 within the preset temperature range.

[0118] In this way, the heating element 20 can be controlled to continuously heat according to the preset operating parameters, so that when the current temperature of the heating element 20 is within the preset temperature range, the heat generated by the heating element 20 and the heat dissipation of the fragrance can be kept in balance, thereby ensuring that the temperature of the heating element 20 can always be within the preset temperature range, and thus ensuring the fragrance diffusion effect of the fragrance device 100.

[0119] Please refer to Figure 2. In some implementations, the preset operating parameter is the preset heating power.

[0120] Specifically, the heat generation is greatly affected by the heating power. Therefore, the heat generation corresponding to different heating powers can be predetermined when the temperature of the heating element 20 is within a preset temperature range. Then, within the preset temperature range, a preset heating power is selected where the difference between the corresponding heat generation and the heat dissipation of the fragrance is within a preset difference range. For example, the preset heating power range is [0.85W, 1.15W], and preferably, it can be 1W.

[0121] 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. Even if there are fluctuations, they are only small fluctuations, thereby ensuring that the current temperature of the heating element 20 is always maintained within the preset temperature range, and thus ensuring the heating effect of the heating element 20.

[0122] Please refer to Figures 1 to 3. In some embodiments, the fragrance device 100 includes a housing 40, and the receiving member 10 is located inside the housing 40.

[0123] Specifically, the housing 40 has an installation space inside, in which the receiving member 10 is installed to fix the receiving member 10, thereby fixing the heating element 20. At the same time, the housing 40 protects the receiving member 10 and the heating element 20 from external damage. The installation space can be a continuous space or a space in different areas, that is, the housing 40 and the heating element 20 can be installed together or separately.

[0124] Please refer to Figures 2 and 3. In some embodiments, the housing 40 includes a cylindrical body 41 and a cover assembly 42. The cover assembly 42 is connected to one end of the cylindrical body 41 to form a receiving cavity, and the receiving member 10 is located in the receiving cavity.

[0125] Specifically, the housing 40 includes a cylindrical body 41 and a cover assembly 42. The cylindrical body 41 is a hollow structure, and one end of the cylindrical body 41 is connected to the cover assembly 42 to form a receiving cavity. The receiving member 10 is located within the receiving cavity to be fixed and protected by the cylindrical body 41 and the cover assembly 42. At least a portion of the heating element 20 extends into the receiving member 10. In this case, the heating element 20 may be partially located in the cover assembly 42 and partially extended into the receiving member 10, or partially located in the receiving cavity and partially extended into the receiving member 10.

[0126] Thus, the housing 40 can be disassembled into a cylindrical body 41 and a cover assembly 42, so that the cavity 11 formed by the cylindrical body 41 and the cover assembly 42 can be used to house the housing 10 and facilitate the assembly of the housing 40, thereby facilitating the assembly of the fragrance device 100.

[0127] Referring to Figures 1 to 3, in some embodiments, the side of the cylinder 41 has a through hole 411, which is configured to expose at least a portion of the receiving member 10, allowing the fragrance generated after the fragrance evaporates to diffuse from the through hole 411. For example, the cylinder 41 is rectangular and includes four sides, each of which may have one or more through holes 411. After the receiving member 10 is installed in the installation space, the receiving member 10 can communicate with the outside, allowing the fragrance generated after the fragrance evaporates to diffuse to the outside through the through hole 411.

[0128] The location of the through hole 411 needs to be determined based on the position of the aroma as it leaves the container 10. In one embodiment, the container 10 is made of a porous material, and the aroma passes through the vent on the side of the container 10. Therefore, the through hole 411 needs to be located in the area of ​​the housing 40 corresponding to the side of the container 10, so that the aroma passing through the vent on the side of the container 10 can flow to the through hole 411 and thus diffuse to the outside. In another embodiment, the container 10 is made of a material with good sealing properties, and the container 10 is provided with a vent. The aroma leaves the container 10 through the vent. Therefore, in this case, the through hole 411 needs to be located in the area of ​​the housing 40 corresponding to the vent of the container 10, so that the aroma leaving the container 10 through the vent can flow to the through hole 411 and thus diffuse to the outside.

[0129] In this way, after the fragrance is generated in the cavity 11, it can be emitted to the outside through the accommodating member 10 and the through hole 411 in sequence to achieve fragrance emission and ensure that the fragrance device 100 can create a fragrance atmosphere in the outside world.

[0130] In another embodiment, the housing 40 is made of a breathable material, in which case the housing 40 may not have a through hole 411, allowing the aroma to pass through the housing 40 and move to the outside.

[0131] Please refer to Figures 2 and 3. In some embodiments, the cylinder 41 has a first opening 412 at one end near the cover assembly 42. The cover assembly 42 includes a seal 421 that seals the first opening 412.

[0132] Specifically, the cylinder 41 has a first opening 412 at one end near the cover assembly 42, so that the receiving member 10 can be installed into the cylinder 41 through the first opening 412. The cover assembly 42 may include a sealing member 421, which abuts against the first opening 412, so that the sealing member 421 can seal the first opening 412 to prevent external substances from entering the cylinder 41 through the first opening 412, and also to prevent the receiving member 10 located inside the cylinder 41 from falling out of the fragrance device 100 through the first opening 412.

[0133] Please refer to Figures 2 and 3. In some embodiments, the seal 421 includes a sealing plate 4211 that seals the first opening 412.

[0134] 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 41, the sealing plate 4211 can still seal the first opening 412. At this time, the end of the cylinder 41 near the cover assembly 42 is tightly combined with the sealing plate 4211. In this way, the cylinder 41 can be used to fix the sealing plate 4211 and even the entire sealing element 421, preventing the sealing plate 4211 from shaking during use, which would make it difficult for the sealing plate 4211 to continuously seal the first opening 412, thereby ensuring that the sealing effect of the sealing element 421 is always good.

[0135] Please refer to Figures 2 and 3. In some embodiments, the receiving 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.

[0136] Specifically, the receiving member 10 is cup-shaped, and the bottom wall 13 and the annular side wall 14 of the receiving member 10 together form a receiving cavity 11. The bottom wall 13 is located at the end of the receiving member 10 away from the cover assembly 42, and the annular side wall 14 has a second opening 12 at the end facing the cover assembly 42, so that the heating element 20 can be inserted into the receiving cavity 11, increasing the contact area between the heating element 20 and the fragrance, thereby facilitating the improvement of the fragrance evaporation rate.

[0137] The fragrance may be partially corrosive, and some areas of the heating element 20 may come into contact with the fragrance, affecting its normal operation, while other areas may not be affected. Therefore, with the second opening 12 provided in the receiving element 10, the fragrance may leak from the second opening 12 to other places.

[0138] Sealing plate 4211 is a flat sealing element used to prevent leakage of fluids (such as water, gas, chemicals, and hydrocarbons). Sealing plate 4211 needs to be made of a corrosion-resistant material to ensure that it can continuously seal the second opening 12.

[0139] 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 world, and protecting other components of the fragrance device 100 from damage.

[0140] Referring to Figures 2 and 3, in some embodiments, the seal 421 includes a first boss 4212 disposed on the sealing plate 4211, and the receiving member 10 is provided with a second boss 15 near the second opening 12. The first boss 4212 is sleeved on the second boss 15, thereby sealing the second opening 12 with the seal 421.

[0141] Specifically, a first protrusion 4212 can be provided on the sealing plate 4211. A second protrusion 15 is provided on the receiving member 10 near the second opening 12, i.e., at the end facing the cover assembly 42. For example, the annular sidewall 14 of the receiving member 10 can be divided into an inner wall and an outer wall. At the end of the receiving member 10 facing the cover assembly 42, the length of the inner wall is longer than the length of the outer wall, so that the end of the receiving member 10 facing the cover assembly 42 forms a second protrusion 15 that is longer inside and shorter outside. The diameter of the first protrusion 4212 is larger than the diameter of the second protrusion 15, so that the first protrusion 4212 can be fitted onto the second protrusion 15, thereby allowing the sealing member 421 to seal the second opening 12.

[0142] In some embodiments, the cylinder 41 can be used to enhance the stability of the connection between the seal 421 and the receiving member 10. When the receiving member 10 is installed in the cylinder 41, the second boss 15 forms 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 fitted onto the second boss 15. At this time, the seal 421 abuts against the receiving member 10 and connects with the cylinder 41, thus completing the installation of the seal 421. Simultaneously, after the first boss 4212 abuts against the bottom of the groove, adhesive can be applied around the area where the first boss 4212 and the groove mate to further improve the sealing effect of the fragrance. The adhesive used can be a structural adhesive suitable for ceramic and plastic bonding.

[0143] In this way, the seal 421 and the receiving member 10 can be joined together to facilitate the assembly of the fragrance device 100, and at the same time ensure that the seal 421 can seal the receiving cavity 11 after joining, thereby ensuring that the fragrance will not leak.

[0144] Referring to Figures 2 and 3, in some embodiments, the fragrance device 100 further includes a circuit board 50 disposed within the cover assembly 42 and located on the side opposite to the receiving member 10 of the seal 421.

[0145] Specifically, the circuit board 50 is disposed inside the cover assembly 42. For example, a recess is provided within the cover assembly 42 to mount the circuit board 50, thereby protecting the circuit board 50 using the cover assembly 42. Since the fragrance has a certain degree of corrosiveness, the circuit board 50 cannot directly contact the fragrance. Therefore, the circuit board 50 is located on the side opposite to the receiving member 10 of the sealing member 421, so that the sealing member 421 isolates the circuit board 50 from the fragrance, thereby preventing the fragrance from damaging the circuit board 50 and improving the safety of the circuit board 50.

[0146] Please refer to Figures 2 and 3. In some embodiments, the seal 421 has a first mounting hole 4213, the heating element 20 is a heating wire, the two ends of the heating element 20 are connected to the circuit board 50, and extend into the receiving cavity 11 through the first mounting hole 4213.

[0147] Specifically, the heating element 20 is a heating wire, allowing its shape to be adjusted as needed. The fragrance has a certain degree of corrosiveness, preventing the circuit board 50 from directly contacting the fragrance, but the heating element 20 needs to be in contact. Therefore, a first mounting hole 4213 can be provided on the sealing element 421, for example, on the sealing plate 4211, for the heating element 20 to pass through. After one end of the heating element 20 is connected to the circuit board 50, the other end of the heating element 20 passes through the first mounting hole 4213, then through the second opening 12, until it extends into the receiving cavity 11. Then, the other end of the heating element 20 extends out of the receiving cavity 11 and again passes through the first mounting hole 4213, finally connecting to the circuit board 50. Simultaneously, the area of ​​the heating element 20 in direct contact with the fragrance must be made of at least a corrosion-resistant material to ensure that the heating element 20 can stably heat the fragrance.

[0148] The number of first mounting holes 4213 can be one or more. For example, one, two or four, depending on the structure of the heating element 20. In one embodiment, the heating element 20 has a U-shaped structure and needs to pass through the first mounting holes 4213 twice, in which case there can be two first mounting holes 4213.

[0149] Thus, a first mounting hole 4213 can be provided on the sealing member 421 to seal the second opening 12, ensuring that the fragrance will not leak, while preventing the fragrance from directly contacting the circuit board 50, and ensuring that after the heating member 20 is connected to the circuit board 50, it can extend into the receiving cavity 11 through the first mounting hole 4213 and the second opening 12 to heat the fragrance.

[0150] Referring to Figures 2 and 3, in some embodiments, the cover assembly 42 includes a loading member 422 connected to the cylinder 41, and a seal 421 located between the loading member 422 and the receiving member 10.

[0151] Specifically, the cover assembly 42 includes a loading member 422, which can be connected to the cylinder 41. The connection method can be a detachable connection method or a non-detachable connection method. The detachable connection method includes threaded connection, snap-fit ​​connection and hinge connection. The non-detachable connection method includes folded connection, riveting connection, adhesive connection and welding connection, etc.

[0152] The seal 421 is located between the loading member 422 and the receiving member 10. The loading member 422 can be used to load components that cannot directly contact the fragrance. For example, a groove can be formed inside the loading member 422, and the components 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, while ensuring that the components installed in the loading member 422 are not damaged by the fragrance.

[0153] Please refer to Figures 2 and 3. In some embodiments, the circuit board 50 is mounted on the loading member 422.

[0154] Specifically, the fragrance has a certain degree of corrosiveness. If the circuit board 50 is directly connected to the fragrance, it may be damaged. Therefore, the loading member 422 can be installed at the end of the seal 421 away from the receiving member 10, and the circuit board 50 can be installed on the loading member 422, for example, by directly soldering it to the surface of the loading member 422 or installing it inside the loading member 422.

[0155] In this way, the safety of the circuit board 50 can be improved while ensuring that the circuit board 50 can control the heating element 20 to heat, thereby ensuring that the circuit board 50 can operate normally and that the heating element 20 can continuously heat the fragrance during the operation of the fragrance device 100.

[0156] Please refer to Figures 2 and 3. In some embodiments, the loading member 422 is at least partially inserted into the first opening 412.

[0157] Specifically, the loading component 422 can be connected to one end of the cylinder 41 near the cover assembly 42. The connection method can be detachable or non-detachable. Detachable connections include threaded connections, snap-fit ​​connections, and hinge connections. Non-detachable connections include folded connections, riveted connections, adhesive connections, and welded connections. Thus, after the loading component 422 is connected to the end of the cylinder 41 near the cover assembly 42, the loading component 422 is at least partially inserted into the first opening 412, completing the connection between the loading component 422 and the cylinder 41. This also facilitates the use of the cylinder 41 to fix the loading component 422, preventing it from shaking during use and causing the circuit board 50 and the heating element 20 connected to the circuit board 50 to shake, thereby ensuring better heating performance of the heating element 20.

[0158] Please refer to Figures 2 and 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 near the first opening 412 of the cylinder body 41. The first engaging member 4222 and the second engaging member 413 engage to at least partially load the loading member 422 into the first opening 412.

[0159] Specifically, the loading component 422 includes a first cover plate 4221 and a first engaging component 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 component 4222 is mainly used for connection with other components. A second engaging component 413 corresponding to the first engaging component 4222 is disposed on the inner wall of the cylinder 41 near the first opening 412. One of the first engaging component 4222 and the second engaging component 413 is a protrusion, and the other is a groove, allowing the first engaging component 4222 and the second engaging component 413 to engage, so that the loading component 422 is at least partially inserted into the first opening 412. The number of first engaging components 4222 and the second engaging component 413 can be one or more, such as one, two, four, or eight. When there are multiple first engaging components 4222 and the second engaging component 413, the number of first engaging components 4222 and the second engaging component 413 are the same and correspond one-to-one. For example, if the first cover plate 4221 is rectangular, first locking members 4222 can be set at each of the four corners of the first cover plate 4221, resulting in four first locking members 4222 and four corresponding second locking members 413. In this way, the connection stability between the loading member 422 and the cylinder 41 can be improved by using multiple first locking members 4222 and second locking members 413.

[0160] Thus, the loading component 422 can be divided into two parts, namely the first cover plate 4221 and the first locking component 4222. The first cover plate 4221 is used to realize the function of loading the circuit board 50, and the first locking component 4222 is used to realize the connection function of the loading component 422, thereby ensuring that the loading component 422 can be installed smoothly, and after installation, the circuit board 50 can supply power to the heating component 20.

[0161] Furthermore, the cylinder 41 and the loading component 422 are connected by a snap-fit ​​mechanism, which facilitates the installation of the cylinder 41 and the loading component 422. At the same time, it is convenient to disconnect the cylinder 41 and the loading component 422 when it is necessary to repair or replace certain components of the fragrance device 100, so as to repair or replace certain components of the fragrance device 100.

[0162] Referring to Figures 2 and 3, in some embodiments, the loading member 422 has a mounting groove 4223, and the circuit board 50 is disposed within the mounting groove 4223. For example, the circuit board 50 can be fixed in the mounting groove 4223 by fasteners such as screws and nuts, or the circuit board 50 can be directly placed into the mounting groove 4223, and an additional component can be provided to connect to the side of the loading member 422 corresponding to the slot of the mounting groove 4223, so that the circuit board 50 is located between the mounting groove 4223 and the component, thereby completing the fixation of the circuit board 50.

[0163] Thus, the mounting slot 4223 provides a stable support platform for the circuit board 50. By fixing the circuit board 50 in the mounting slot 4223 with fasteners such as screws and nuts, the stability and reliability of the circuit board 50 can be significantly enhanced, preventing it from shifting or being damaged due to vibration or external force during use.

[0164] Please refer to Figures 2 and 3. In some embodiments, the bottom wall of the mounting groove 4223 is provided with a second mounting hole 4224, through which the heating element 20 extends into the receiving cavity 11.

[0165] Specifically, the bottom wall of the mounting groove 4223 is provided with a second mounting hole 4224. The size of the second mounting hole 4224 is determined according to the size of the heating element 20 to ensure that the heating element 20 can pass through the second mounting hole 4224. The heating element 20 can extend into the receiving member 10 through the second mounting hole 4224, so that the extended part of the heating element 20 can pass through the second mounting hole 4224 and the first mounting hole 4213 of the sealing plate 4211 in sequence, and thus extend into the receiving cavity 11 through the second opening 12, so as to ensure that the heating element 20 can heat the fragrance adsorbed in the adsorbent 30 in the receiving cavity 11.

[0166] Thus, the circuit board 50 can be installed by opening a mounting slot 4223 in the loading member 422, and the mounting slot 4223 is provided with a second mounting hole 4224 for the heating element 20 to pass through. This ensures that the circuit board 50 can be protected by the sealing member 421 after installation, and that the heating element 20 can extend into the receiving member 10 through the second mounting hole 4224 to heat the fragrance.

[0167] Referring to Figures 2 and 3, in some embodiments, the cover assembly 42 further includes a cover 423 disposed on the loading member 422, which is located between the seal 421 and the cover 423.

[0168] Specifically, the cover 423 is disposed on the loading component 422 and can be connected to the loading component 422. The connection method can be a detachable connection method or a non-detachable connection method. The detachable connection method includes threaded connection, snap-fit ​​connection and hinge connection, and the non-detachable connection method includes folded edge connection, riveting connection, adhesive connection and welding connection, etc.

[0169] The loading component 422 is located between the sealing component 421 and the cover 423, meaning that the opposite ends of the loading component 422 are connected to the sealing component 421 and the cover 423 respectively. This allows the cover 423 to cover at least a portion of the outward-facing end of the loading component 422, ensuring a clean appearance of the fragrance device 100 and improving its aesthetics. Simultaneously, the cover 423 further enhances the security of the circuit board 50 within the loading component 422.

[0170] In one embodiment, the fragrance device 100 includes a power supply assembly connected to the heating element 20 to provide electrical energy to the heating element 20. The power supply assembly is located within the cover assembly 42 and connected to the heating element 20 to power the heating element 20, ensuring that the heating element 20 can heat up. At this time, the cover 423 can completely cover the end of the mounting member 422 facing the outside, further increasing the protective effect of the cover 423.

[0171] In another embodiment, referring to Figure 5, the power supply component 200 is a component other than the fragrance device 100. In this case, a perforation 42311 can be provided on the cover 423. The cover 423 can cover a portion of the outer end of the mounting component 422 facing the outside. The cover 423 can also specifically cover the area of ​​the outer end of the mounting component 422 that would affect the aesthetics of the fragrance device 100, thus ensuring the cleanliness of the fragrance device 100's appearance and ensuring that the heating element 20 can be connected to and powered by the external power supply component 200 through the perforation 42311. Simultaneously, the cover 423 further prevents the heating element 20 installed on the mounting component 422 from external damage.

[0172] Thus, the cover assembly 42 can further improve the safety of the heating element 20 by providing the cover 423. At the same time, the cover 423 can also cover at least a portion of the area of ​​the loading element 422 away from the receiving element 10, so as to ensure the clean appearance of the fragrance device 100 and improve the aesthetics of the fragrance device 100.

[0173] Referring to Figures 2 and 3, in some embodiments, the cover 423 includes a second cover plate 4231 and a side plate 4232 disposed 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 within the mounting groove 4223. The side plate 4232 is connected to the loading member 422.

[0174] 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 423 as a whole presents a bowl shape. At the same time, the side plate 4232 can be connected to the loading component 422, wherein the connection method can be a detachable connection method or a non-detachable connection method. Detachable connection methods include threaded connection, snap connection and hinge connection, and non-detachable connection methods include folded connection, riveted connection, adhesive connection and welded connection, etc. When the side plate 4232 is connected to the loading component 422, it can be considered that the cover 423 is fastened to the loading component 422. At this time, the second cover plate 4231 connected to the side plate 4232 can cover at least a part of the area of ​​the end of the loading component 422 facing the outside.

[0175] 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 engage. 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.

[0176] In this design, one of the third and fourth engaging components 4225 is a protrusion, and the other is a groove, allowing the third and fourth engaging components 4225 to engage to connect the side plate 4232 and the loading component 422. The number of third and fourth engaging components 4225 can be one, two, four, or eight. When there are multiple third and fourth engaging components 4225, the number of each component is the same and they correspond one-to-one. Thus, the connection between the side plate 4232 and the loading component 422 can be achieved through engagement. Furthermore, when there are multiple third and fourth engaging components 4225, the multiple components improve the connection stability between the loading component 422 and the cylinder 41.

[0177] The second cover plate 4231 is used to at least partially seal the mounting groove 4223. That is, along the normal direction of the second cover plate 4231, the second cover plate 4231 is at least partially located within the outline of the mounting groove 4223 in the orthographic projection of the loading member 422, so as to at least partially cover the side of the circuit board 50 facing the outside in the mounting groove 4223, thereby protecting the circuit board 50 in the mounting groove 4223.

[0178] Thus, the cover 423 can be divided into two areas: a second cover plate 4231 and a side plate 4232. The side plate 4232 is mainly used to connect with the loading component 422. The second cover plate 4231 can be used to cover at least a portion of the area of ​​the end of the mounting groove 4223 facing the outside, thereby facilitating the installation of the cover 423 and realizing the covering function of the cover 423.

[0179] Please refer to Figures 2 and 3. In some embodiments, the second cover plate 4231 has a through hole 42311, which is disposed opposite to the circuit board 50. The through hole 42311 is used to allow the circuit board 50 to be connected to the outside.

[0180] Specifically, the circuit board 50 needs to connect to an external power supply component and obtain electrical energy. Therefore, a through hole 42311 can be provided on the second cover plate 4231, and the through hole 42311 is positioned opposite to the circuit board 50. The through hole 42311 is connected to the mounting groove 4223, so that the external power supply component can pass through the through hole 42311 through the second cover plate 4231 and connect to the circuit board 50. This ensures that the circuit board 50 can connect to the outside world and obtain electrical energy while being protected by the second cover plate 4231.

[0181] Referring to Figures 2 and 3, in some embodiments, the circuit board 50 includes a solder portion 51 located outside the outline of the through hole 42311 projected onto the circuit board 50, so that the second cover plate 4231 shields the solder portion 51 of the circuit board 50.

[0182] Specifically, after the circuit board 50 is installed on the loading member 422, at least a portion of the circuit board 50 is exposed to the outside. The heating element 20 is connected to the solder joint 51 of the circuit board 50. It is understood that the solder joint of the heating element 20 is located on the solder joint 51; if the solder joint is damaged by external factors, it will affect the normal operation of the heating element 20. At the same time, to prevent the loading member 422 itself from wearing down the solder joint, the solder joint 51 is generally located on the side of the circuit board 50 facing the outside. Therefore, the second cover plate 4231 needs to cover the solder joint 51 so that it is not exposed to the outside.

[0183] The solder joint 51 is located in the projection of the through hole 42311 onto the circuit board 50, which refers to the projection of the solder joint 51 onto the circuit board 50 in the normal direction of the second cover plate 4231. The position of the through hole 42311 is set according to the position of the solder joint 51 on the circuit board 50 so that the solder joint 51 is outside the outline of the projection of the through hole 42311 onto the circuit board 50. It can be understood that the area covered by the projection of the second cover plate 4231 onto the circuit board 50 is the area of ​​the circuit board 50 that is blocked by the second cover plate 4231. This ensures that the solder joint 51 is blocked by the area of ​​the second cover plate 4231 other than the through hole 42311.

[0184] 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 solder joint 51 of the circuit board 50 can be obtained. The radius of the through hole 42311 can be determined based on the distance between the center of the circuit board 50 and the solder joint 51 of the circuit board 50. This radius is at least less than or equal to the distance between the center of the circuit board 50 and the solder joint 51 of the circuit board 50. Then, the through hole 42311 is set with the center of the second cover plate 4231 as the center and the determined distance as the radius.

[0185] In this way, it can be ensured that there is no solder part 51 of circuit board 50 in the area of ​​the loading component 422 exposed to the outside through the perforation 42311, so as to block the solder joint of heating component 20 on the solder joint 51, thereby ensuring the clean appearance of the fragrance device 100 and preventing the potential for damage to the heating circuit caused by exposed solder joints.

[0186] Please refer to Figures 1 and 2. In some embodiments, the fragrance device 100 also includes a decorative element 60, which is mounted on the housing 40.

[0187] Specifically, the fragrance device 100 may also be provided with decorative elements 60, and the number of decorative elements 60 may be one or more, such as one, two or four, depending on the needs.

[0188] Please refer to Figures 1 and 2. In some embodiments, the decorative element 60 is connected to one end of the cylindrical body 41 of the housing 40 away from the cover assembly 42 of the housing 40.

[0189] Specifically, the cover assembly 42 is connected to one end of the cylinder 41, and the decorative part 60 is connected to the end of the cylinder 41 away from the cover assembly 42. The connection method can be a detachable connection method or a non-detachable connection method. Detachable connection methods include threaded connection, snap-fit ​​connection and hinge connection, while non-detachable connection methods include folded edge connection, riveting connection, adhesive connection and welding connection, etc.

[0190] The decorative element 60 is located at the end of the cylinder 41 that is away from the cover assembly 42. This ensures that the decorative element 60 will not affect the installation and operation of the heating element 20 installed on the cover assembly 42. At the same time, the decorative element 60 can also enhance the aesthetics of the fragrance device 100.

[0191] Thus, the fragrance device 100 can be equipped with decorative parts 60 without affecting the operation of each component in the fragrance device 100, so as to ensure that the fragrance device 100 can diffuse fragrance efficiently on the one hand, and improve the aesthetics of the fragrance device 100 on the other hand.

[0192] Please refer to Figures 1 and 2. In some embodiments, the decorative element 60 includes a first decorative element 61, which is connected to the end of the cylinder 41 opposite to the cover assembly 42.

[0193] Specifically, the connection between the first decorative element 61 and the end of the cylinder 41 facing away from the cover assembly 42 can be a detachable connection or a non-detachable connection. Detachable connection methods include threaded connection, snap-fit ​​connection and hinge connection, while non-detachable connection methods include folded edge connection, riveted connection, adhesive connection and welded connection.

[0194] Thus, the fragrance device 100 can be equipped with a first decorative element 61 without affecting the operation of each component in the fragrance device 100, so as to ensure that the fragrance device 100 can diffuse fragrance efficiently on the one hand, and improve the aesthetics of the fragrance device 100 on the other hand.

[0195] In some embodiments, the first decorative element 61 includes a fixing groove 611, and the cylindrical body 41 includes a third boss 414, which is embedded in the fixing groove 611, thereby connecting the first decorative element 61 to the cylindrical body 41.

[0196] Specifically, a fixing groove 611 can be formed inside the first decorative piece 61, and the end of the cylindrical body 41 facing away from the cover assembly 42 can extend in the direction facing away from the cover assembly 42 to form a third protrusion 414. The shape and size of the third protrusion 414 match the fixing groove 611, so that the third protrusion 414 can be embedded in the fixing groove 611, thereby realizing the connection between the first decorative piece 61 and the cylindrical body 41.

[0197] For example, the fixing groove 611 is provided with a fifth engaging member 6111, and the third protrusion 414 is provided with a sixth engaging member 4141. The fifth engaging member 6111 and the sixth engaging member 4141 engage with each other. One of the fifth engaging member 6111 and the sixth engaging member 4141 is a protrusion, and the other is a groove, allowing them to engage to connect the first decorative member 61 and the cylindrical body 41. The number of fifth engaging members 6111 and the sixth engaging member 4141 can be one or more, such as one, two, four, or eight. Thus, the connection between the first decorative member 61 and the cylindrical body 41 can be achieved through engagement. Furthermore, when there are multiple fifth engaging members 6111 and the sixth engaging member 4141, the multiple fifth engaging members 6111 and the sixth engaging member 4141 can improve the connection stability between the first decorative member 61 and the cylindrical body 41.

[0198] In other embodiments, it can be achieved solely by the third boss 414 and the fixing groove 611. In this case, the third boss 414 and the fixing groove 611 can be an interference fit, thereby ensuring that the third boss 414 will not easily detach from the fixing groove 611 after it is installed into the fixing groove 611.

[0199] Thus, the first decorative piece 61 and the cylinder 41 can be stably connected by the third boss 414 and the fixing groove 611, thereby ensuring that the first decorative piece 61 will not easily fall off during the use of the fragrance device 100.

[0200] Please refer to Figures 1 and 2. In some embodiments, the decorative element 60 further includes a second decorative element 62, which is disposed on the side of the first decorative element 61 opposite to the cylinder 41.

[0201] Specifically, there may be two decorative elements 60, namely a first decorative element 61 and a second decorative element 62. The first decorative element 61 is connected to the end of the cylinder 41 that is away from the cover assembly 42, and the second decorative element 62 is disposed on the side of the first decorative element 61 that is away from the cylinder 41.

[0202] The connection between the first decorative component 61 and the second decorative component 62 can be either a detachable connection or a non-detachable connection. Detachable connections include threaded connections, snap-fit ​​connections, and hinge connections, while non-detachable connections include folded connections, riveted connections, adhesive connections, and welded connections. Preferably, the first decorative component 61 and the second decorative component 62 can be connected with adhesive to simplify the connection process.

[0203] In this way, the aesthetics of the fragrance device 100 can be further enhanced by using two decorative pieces 60, while ensuring that neither decorative piece 60 will affect the operation of the various components in the fragrance device 100.
