Description

Technical Field

[0001] This utility model belongs to the field of aromatherapy machine technology, specifically a scented water-heated blanket knob. Background Technology

[0002] Aroma stones, also known as fragrance stones, are typically made of porous materials such as plaster, unglazed ceramics, and soapstone, which have a microporous structure. When essential oils are dropped onto a fragrance stone, they are absorbed by these pores. Since essential oil molecules are volatile, they will naturally and slowly evaporate from the surface of the fragrance stone into the surrounding air due to capillary action.

[0003] Heating aroma stones can make the fragrance diffuse faster, but existing technologies often result in uneven heating of the aroma stones, which can cause essential oils to clog the pores and affect the absorption and volatilization of new essential oils. In addition, the uncontrollable temperature of the device can cause the active ingredients in most essential oils to decompose, resulting in a change in the fragrance. The complex molecular structure of some essential oils, such as sandalwood and frankincense, can be permanently degraded at high temperatures. Furthermore, traditional aroma boxes cannot adjust the aroma stone fixing device or the aroma concentration, making them unsuitable for different sizes of aroma stones and different scenarios. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a scented water-heated blanket knob to solve the problems of poor adaptability of the aromatherapy box, inability to adjust the heating of the aromatherapy, and uneven heating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scented water-heated blanket knob, characterized in that it includes a shell, a top cover, and an iris mechanism. The shell and the top cover are both cylindrical, and the shell is hollow inside and cylindrical. An inner cavity is provided inside the shell, and a groove is provided on the bottom surface of the inner cavity. The groove is semi-circular, and the top surface of the inner cavity is also hollow. The height of the inner cavity is lower than the height of the shell. The top surface of the top cover is parallel to the top surface of the shell. The shell, the top cover, and the inner cavity form an assembly for accommodating scented stones. The iris mechanism is located between the top cover and the inner cavity, and the iris mechanism is connected to the bottom surface of the top cover and abuts against the top surface of the inner cavity.

[0006] Optionally, a fixed post is provided at the center of the bottom surface of the inner cavity. The fixed post is cylindrical and has a threaded post inside. The fixed post can extend and retract up and down by rotating the threaded post. Magnets are arranged in a circular array at the point where the top surface of the inner cavity abuts against the iris mechanism.

[0007] Optionally, the bottom surface of the inner cavity is further provided with a honeycomb heat-conducting sheet, which surrounds the fixing post and covers the entire bottom surface of the inner cavity, and the honeycomb heat-conducting sheet has a circumferential array of multiple honeycomb holes.

[0008] Optionally, the iris mechanism consists of a base plate, a ring, a rotating rod, and blades. The base plate has a circumferential array of multiple sliding pins, and the ring has a groove corresponding to the sliding pin. The rotating rod is located on the side of the sliding pin and the groove, with one end connected to the ring and the other end connected to the blade. The sliding pin moves in the groove, driving the rotating rod to rotate, causing the blade to retract or expand synchronously. The ring has a magnetic piece, and the ring abuts against the top surface of the inner cavity through the attraction between the magnetic piece and the magnet.

[0009] Optionally, a temperature sensor is provided on the outer surface of the housing.

[0010] Optionally, the upper cover has a circular groove on its side, and the connection between the outer shell and the upper cover has a silicone sealing strip with the same shape as the circular groove. The upper cover also has a patterned cutout.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention includes an iris mechanism connected to the top cover. After the user drips in essential oil, the iris mechanism comes into contact with the top surface of the inner cavity through the attraction between the magnetic sheet and the magnet. At this time, rotating the top cover causes the sliding pin to move in the sliding groove, driving the rotating rod to rotate, causing the blades to close or open synchronously, thereby adjusting the fragrance concentration. When the user needs a stronger fragrance diffusion effect, the blades can be adjusted to maximize the hollow area, allowing more fragrance liquid to evaporate; if a lighter fragrance concentration is desired, the hollow area can be reduced by adjusting the blades, thereby controlling the amount of fragrance liquid evaporating. This allows for autonomous adjustment of the indoor fragrance concentration, enabling the device to adapt to different scene needs and thus making the device more adaptable.

[0013] In this utility model, the user can extend and retract the fixing column by rotating the threaded column. The user can adjust the height of the fixing column according to the size and thickness of the fragrance stone, ensuring that the fragrance stone is placed stably while adapting to fragrance stones of different sizes, thus increasing the versatility and adaptability of the product.

[0014] In this invention, a honeycomb heat-conducting sheet is provided on the bottom surface of the inner cavity. The honeycomb heat-conducting sheet can more effectively guide the heat from the host controller and distribute it evenly on the diffuser stone, thereby accelerating the evaporation and diffusion efficiency of the fragrance liquid.

[0015] This invention incorporates a temperature sensor. When the controller starts heating, the temperature sensor monitors the device temperature in real time. When the temperature exceeds 50°C, the LED on the temperature sensor flashes red and transmits an electrical signal to the controller to stop heating, thus achieving more precise temperature control to prevent the loss of essential oil activity.

[0026] like Figures 1 to 7 As shown, this utility model provides a scented water-heated blanket knob, characterized in that it includes a shell 1, a top cover 2, and an iris mechanism 3. Both the shell 1 and the top cover 2 are cylindrical, and the shell 1 is hollow and cylindrical. The shell 1 has an inner cavity 4 inside, and a groove 20 is provided on the bottom surface of the inner cavity 4. The groove 20 is semi-circular, and the top surface of the inner cavity 4 is also hollow. The height of the inner cavity 4 is lower than the height of the shell 1. The top surface of the top cover 2 is parallel to the top surface of the shell 1. The shell 1, the top cover 2, and the inner cavity form an assembly for accommodating the scented stone. The iris mechanism 3 is located between the top cover 2 and the inner cavity 4, and the iris mechanism 3 is connected to the bottom surface of the top cover 2 and abuts against the top surface of the inner cavity 4.

[0027] Specifically, the groove 20 is interlocked with the water-heated blanket controller. The water-heated blanket controller uses the groove 20 to heat the device. A completely independent and physically isolated special groove or buckle is designed on the outer shell of the water-heated blanket main unit. This is used to place the device to use the heat and natural airflow generated when the main unit is running to help the fragrance evaporate. It also ensures that the fragrance knob is absolutely sealed and completely isolated from the water circuit and electrical circuit. The fragrance medium will not come into contact with the internal components, which also makes the device and the water-heated blanket a whole, so that the water-heated blanket can emit fragrance when heated.

[0028] A fixed post 5 is provided at the center of the bottom surface inside the inner cavity 4. The fixed post 5 is cylindrical and has a threaded post 6 inside. The fixed post 5 can extend and retract up and down by rotating the threaded post 6. Magnets 7 are arranged in a circular array at the point where the top surface of the inner cavity 4 abuts against the iris mechanism 3.

[0029] Specifically, in this utility model, the user can rotate the threaded column 6 to extend and retract the fixing column 5. The user can adjust the height of the fixing column 5 according to the size and thickness of the fragrance stone, ensuring that the fragrance stone is placed stably while adapting to fragrance stones of different specifications, thus increasing the versatility and adaptability of the product.

[0030] The bottom surface of the inner cavity 4 is also provided with a honeycomb heat-conducting sheet 8, which surrounds the fixing post 5 and covers the entire bottom surface of the inner cavity 4. The honeycomb heat-conducting sheet 8 has multiple honeycomb holes arranged in a circular array.

[0031] Specifically, in this utility model, the bottom surface of the inner cavity 4 is provided with a honeycomb heat-conducting sheet 8. The honeycomb heat-conducting sheet 8 can more effectively guide the heat from the water-heated blanket host controller and distribute it evenly on the diffuser stone, thereby accelerating the evaporation and diffusion efficiency of the fragrance liquid.

[0032] The iris mechanism 3 consists of a base plate 9, a ring 10, a rotating rod 11, and blades 12. The base plate 9 has a plurality of sliding pins 13 arranged in a circular array. The ring 10 is provided with a sliding groove 14 corresponding to the sliding pins 13. The rotating rod 11 is located on the side of the sliding pins 13 and the sliding groove 14. One end of the rotating rod 11 is connected to the ring 10, and the other end is connected to the blades 12. The sliding pins 13 move in the sliding groove 14, driving the rotating rod 11 to rotate, so that the blades 12 can be closed or opened synchronously. The ring 10 is provided with a magnet 15. The ring 10 abuts against the top surface of the inner cavity 4 by the attraction between the magnet 15 and the magnet 7.

[0033] Specifically, this utility model includes an iris mechanism 3 connected to the upper cover 2. After the user drips in essential oil, the iris mechanism 3 comes into contact with the top surface of the inner cavity 4 through the attraction between the magnetic piece 15 and the magnet 7. At this time, the upper cover 2 is rotated, and the sliding pin 13 moves in the sliding groove 14, driving the rotating rod 11 to rotate, causing the blade 12 to close or open synchronously, thereby adjusting the fragrance concentration. When the user needs a stronger fragrance diffusion effect, the blade 12 can be adjusted to maximize the hollow area, allowing more fragrance liquid to evaporate; if a lighter fragrance concentration is desired, the hollow area can be reduced by adjusting the blade 12, thereby controlling the amount of fragrance liquid evaporating, achieving autonomous adjustment of the indoor fragrance concentration, so that the device can adapt to different scene needs, and can be used without affecting the heating of the water-heated blanket, thus making the device more adaptable.

[0034] A temperature sensor 16 is provided on the outer surface of the housing 1.

[0035] Specifically, this utility model is equipped with a temperature sensor 16. When the controller starts heating, the temperature sensor 16 detects the temperature of the device in real time. When the temperature is greater than 50°C, the LED light on the temperature sensor 16 flashes red and transmits an electrical signal to the controller to stop heating, thereby achieving more precise temperature control to prevent the loss of essential oil activity.

[0036] The upper cover 2 has a circular groove 17 on its side, and a silicone sealing strip 18 with the same shape as the circular groove 17 is provided at the connection between the outer shell 1 and the upper cover 2. The upper cover 2 has a patterned cutout 19.

[0037] The working principle and usage process of this utility model: After the user drips in the essential oil, the iris mechanism 3 abuts against the top surface of the inner cavity 4 through the attraction between the magnetic piece 15 and the magnet 7. At this time, rotating the top cover 2 causes the sliding pin 13 to move in the sliding groove 14, driving the rotating rod 11 to rotate, so that the blades 12 simultaneously close or open, thereby adjusting the fragrance concentration. When the user needs a stronger fragrance diffusion effect, the blades 12 can be adjusted to maximize the hollow area, allowing more fragrance liquid to evaporate; if a lighter fragrance concentration is desired, the hollow area can be reduced by adjusting the blades 12, thereby controlling the amount of fragrance liquid evaporating, thus achieving a lighter fragrance concentration in the room. The ability to autonomously adjust the fragrance concentration allows the device to adapt to different scenarios, thus increasing its versatility. In this invention, the user can rotate the threaded column 6 to extend and retract the fixing column 5. The user can adjust the height of the fixing column 5 according to the size and thickness of the fragrance stone, ensuring that the fragrance stone is placed stably while accommodating fragrance stones of different sizes, increasing the product's versatility and adaptability. In this invention, the bottom surface of the inner cavity 4 is provided with a honeycomb heat-conducting plate 8, which can more effectively guide and evenly distribute the heat from the host controller onto the fragrance stone, accelerating the evaporation and diffusion efficiency of the fragrance liquid.
