Description

Technical Field

[0001] This utility model relates to the field of fragrance diffuser technology, specifically to a fragrance diffuser with adjustable fragrance concentration. Background Technology

[0002] As people's demands for quality of life increase, they often use methods such as spraying perfumes or essential oils into the air to improve and maintain air freshness, eliminate odors, or sterilize and disinfect.

[0003] Most fragrance diffusers on the market currently do not allow for direct adjustment of fragrance concentration. This can lead to situations where the fragrance concentration is too low for users to perceive, or too high, causing discomfort and affecting the user experience.

[0004] To solve this problem, a diffuser cover with multiple diffuser holes is usually installed and placed on the mouth of the liquid storage bottle. Then, a concentration adjustment cover with through holes along its own circumference is rotatably connected to the outside of the diffuser cover, so that the diffuser holes and through holes can move relative to each other to form a staggered blockage, thereby adjusting the gap between the inner cavity of the fragrance diffuser and the outside, so that the concentration of fragrance diffusion can be adjusted to meet the fragrance concentration requirements of different occasions.

[0005] However, the concentration adjustment technology of related fragrance diffusers, which uses the relative misalignment between the diffuser hole and the through hole to adjust the fragrance concentration, has a complex adjustment structure, is difficult to operate, and is prone to wear, resulting in high usage and maintenance costs, short lifespan, and negative impact on user experience.

[0057] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0058] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0060] The following is combined with Figures 1 to 5 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0061] Combination Figures 1 to 5 An embodiment of this utility model provides an adjustable fragrance diffuser, which includes a support base 100, a liquid storage bottle 200, an adsorption core 300, a evaporation cap 400, a heating element 500, a control unit 600, and a power supply unit 700.

[0062] The support base 100 has a fixed head 110 and a support body 120, and the support body 120 has an accommodating space 121.

[0063] The liquid storage bottle 200 has a bottle mouth 210 and a bottle body 220. The bottle mouth 210 is detachably connected to the fixing head 110, and the bottle body 220 is placed in the receiving space 121.

[0064] The first end of the adsorption core 300 extends into the liquid storage bottle 200, and the second end of the adsorption core 300 extends out of the liquid storage bottle 200 from the bottle opening 210. The fragrance liquid in the liquid storage bottle 200 can flow from the first end of the adsorption core 300 to the second end.

[0065] The evaporation cap 400 has a receiving cavity 410 and an evaporation hole 420. The evaporation hole 420 connects the receiving cavity 410 with the external environment. The second end of the adsorption core 300 is located in the receiving cavity 410, so that the fragrance liquid flowing to the second end of the adsorption core 300 can diffuse out of the external environment through the evaporation hole 420 to achieve fragrance diffusion.

[0066] The heating element 500 is fitted at the second end of the adsorption core 300 to heat the second end of the adsorption core 300 in order to accelerate the diffusion of the fragrance liquid.

[0067] The control unit 600 is electrically connected to the heating element 500 and can control the temperature state of the heating element 500; the heating element 500 can generate different temperatures to heat the second end of the adsorption core 300 at different temperatures, so that the fragrance liquid has different diffusion rates, thereby the fragrance concentration can be adjusted, and the fragrance concentration adjustment is simpler.

[0068] The power supply unit 700 supplies power to the heating element 500 and the control unit 600, ensuring the normal operation of the control unit 600 and the heating element 500.

[0069] It is understood that the adjustable fragrance diffuser provided in the embodiments of this utility model is configured with a support base 100 having a fixed head 110, a supporting body 120, and a receiving space 121; the bottle mouth 210 of the liquid storage bottle 200 is detachably connected to the fixed head 110, the bottle body 220 of the liquid storage bottle 200 is placed in the receiving space 121, the first end of the adsorption core 300 extends into the liquid storage bottle 200, and the second end of the adsorption core 300 extends out of the bottle mouth 210; and an evaporation cap 4 has a receiving cavity 410 and an evaporation hole 420. The evaporation pore 420 connects the receiving cavity 410 to the external environment. The second end of the adsorption core 300 is located in the receiving cavity 410. The heating element 500 is sleeved on the second end of the adsorption core 300, and a control unit 600 is set to control the heating element 500 to generate different temperatures. This allows the second end of the adsorption core 300 to be heated at different temperatures, resulting in different diffusion rates of the fragrance liquid. As a result, the concentration of the fragrance can be adjusted. The concentration adjustment structure is simpler, the operation is more convenient, there is no wear phenomenon, the use and maintenance costs are reduced, and the user experience is improved.

[0070] Specifically, in combination Figure 1 and Figure 4In some embodiments of this utility model, the control unit 600 includes a control button 610 and a processing unit 620. The control button 610 is electrically connected to the processing unit 620, and the processing unit 620 is electrically connected to the heating element 500.

[0071] The control button 610 has a strong setting, a light setting, a timer setting, and an off setting.

[0072] When the control button 610 is in the concentrated setting, the processing unit 620 controls the heating element 500 to be at the first temperature, which can be 90±7℃, such as 90℃.

[0073] When the control button 610 is in the low setting, the processing unit 620 controls the heating element 500 to be at a second temperature, which is lower than the first temperature. The temperature value of the second temperature can be 70±7℃, such as 70℃.

[0074] When the control button 610 is in the off position, the processing unit 620 controls the heating element 500 to stop heating, and the fragrance liquid can stop diffusing.

[0075] When control button 610 is set to the timer setting, processing unit 620 controls heating element 500 to stop heating after a preset time. For example, processing unit 620 controls heating element 500 to automatically stop heating after four hours. This makes adjusting the fragrance concentration of the diffuser more convenient and demonstrates a high degree of intelligence.

[0076] It should be noted that after the fragrance diffuser is connected to a power source, pressing the control button 610 once activates the light setting; pressing the control button 610 twice activates the strong setting; pressing and holding the control button 610 for a long time activates the timer setting; and pressing the control button 610 a third time activates the off setting, turning off the fragrance diffuser.

[0077] To improve the visibility of controlling the fragrance concentration of this diffuser and further facilitate user operation, combined with... Figure 1 and Figure 4 In some embodiments of this utility model, the control unit 600 further includes a first indicator light 601, a second indicator light 602, and a third indicator light 603.

[0078] When the control button 610 is in the off position, the processing unit 620 controls the first indicator light 601 to light up.

[0079] When the control button 610 is in the high position, the processing unit 620 controls the second indicator light 602 to light up.

[0080] When the control button 610 is in the off position, the processing unit 620 controls all indicator lights to turn off.

[0081] When the control button 610 is in the timer setting, the processing unit 620 controls the first indicator light 601 and the third indicator light 603 to light up simultaneously. At this time, the fragrance diffuser will continue to run for a preset time (e.g., four hours) in the light setting before stopping.

[0082] When the control button 610 is in the timer setting, the processing unit 620 controls the second indicator light 602 and the third indicator light 603 to light up simultaneously. At this time, the fragrance diffuser will continue to run in the strong setting for a preset time (for example, four hours) before stopping.

[0083] In other words, after the fragrance diffuser is connected to a power source, pressing the control button 610 once activates the light setting, and the first indicator light 601 illuminates; pressing the control button 610 twice activates the strong setting, and the second indicator light 602 illuminates; in the light setting, pressing and holding the control button 610 activates the timer setting, and the first indicator light 601 and the third indicator light 603 illuminate simultaneously, and the fragrance diffuser runs continuously for the preset light setting time (e.g., four hours) before stopping; in the strong setting, pressing and holding the control button 610 activates the timer setting, and the second indicator light 602 and the third indicator light 603 illuminate simultaneously, and the fragrance diffuser runs continuously for the preset strong setting time (e.g., four hours) before stopping; pressing the control button 610 a third time activates the off setting, turning off the fragrance diffuser, and the first indicator light 601, the second indicator light 602, and the third indicator light 603 all turn off simultaneously.

[0084] Combination Figure 2 In some embodiments of this utility model, the power supply unit 700 includes a power supply head 710, a fixing head 110 is disposed at the first end of the supporting body 120, and the power supply head 710 is disposed at the second end of the supporting body 120.

[0085] The control unit 600 is located on the supporting body 120, which makes the overall structure of the fragrance diffuser simpler and requires less space for installation.

[0086] Combination Figure 2 In some embodiments of this utility model, the fragrance diffuser also includes a cover 800, which covers the supporting body 120 and can form an installation space 810.

[0087] The control button 610, the first indicator light 601, the second indicator light 602 and the third indicator light 603 are all located on the cover 800, and the processing unit 620 is located on the support body 120 and within the installation space 810; this further improves the rationality of the layout of the various components of the fragrance diffuser and reduces the space occupied.

[0088] Combination Figure 2 In some embodiments of this utility model, the first end of the cover 800 is snapped into the receiving cavity 410 and connected to the evaporation cap 400, making the cover 800 more securely fixed.

[0089] The first end of the cover 800 is provided with a mounting part 820, and the heating element 500 is located on the mounting part 820 to prevent the heating element 500 from becoming loose and to improve the stability of the heating element 500, thereby improving the temperature control accuracy of the second end of the adsorption core 300 and further improving the accuracy of aroma concentration adjustment.

[0090] Combination Figure 1 and Figure 2 In some embodiments of this utility model, the evaporation cap 400 includes a cap cylinder 401 and a top cap 402.

[0091] The top cover 402 is detachably mounted on the cover cylinder 401, which forms a receiving cavity 410. The evaporation hole 420 is provided on the top cover 402, and the aroma can be emitted from the evaporation hole 420.

[0092] The evaporation hole 420, heating element 500 and adsorption core 300 are coaxially arranged so that the fragrance liquid adsorbed to the second end of the adsorption core 300 can better evaporate into the external environment and improve the effective range of fragrance diffusion.

[0093] Combination Figure 5 In order to prevent the fragrance liquid in the storage bottle 200 from evaporating naturally and to avoid waste, in some embodiments of this utility model, the storage bottle 200 also includes a bottle cap 230, which is detachably set at the bottle mouth 210.

[0094] When the fragrance diffuser is in use, the cap 230 is removed from the opening 210.

[0095] When the fragrance diffuser stops, the bottle cap 230 is placed on the bottle opening 210, and the bottle cap 230 covers the adsorption core 300.

[0096] In addition, combined Figure 2 In some embodiments of this utility model, the bottle body 220 is located below the cap cylinder 401.

[0097] The cap 401 is coaxially arranged with the bottle body 220, and a section of the supporting body 120 that forms the accommodating space 121 is located on one side of the bottle body 220, which further saves the space required for installation and increases the applicability of the fragrance diffuser.

[0098] Of course, combined Figure 2 In some embodiments of this utility model, the bottom of the liquid storage bottle 200 is concave outward in an arc shape.

[0099] The first end of the adsorption core 300 abuts against the recessed area at the bottom of the liquid storage bottle 200, so that the fragrance liquid in the liquid storage bottle 200 can be adsorbed by the adsorption core 300 to the maximum extent, thereby improving the utilization efficiency of the fragrance liquid, avoiding waste and reducing usage costs.
