[0020] The following is a reference appendix. Figure 1-6 This application describes an adjustable temperature wall-mounted electric aromatherapy diffuser.
[0021] Existing aromatherapy diffusers simply heat the wick and cannot regulate the evaporation rate of essential oils, thus failing to meet users' requirements for the concentration of aromatherapy in a space.
[0022] Therefore, this utility model provides an adjustable temperature wall-mounted electric aromatherapy diffuser, such as... Figure 1-3 As shown, the device includes an outer shell 1, a glass bottle 2 for storing essential oils detachably connected to the outer shell 1, a core rod 3 inside the glass bottle 2, one end of the core rod 3 being close to the bottom of the glass bottle 2, a cement resistor 4 inside the outer shell 1, a hot air flow hole 401 on the cement resistor 4, and the end of the core rod 3 away from the bottom of the glass bottle 2 being located inside the hot air flow hole 401 to exchange heat with the cement resistor 4. A rocker switch 5 is also provided on the outer shell 1, and a metal film resistor 6 is provided inside the outer shell 1, located around the core rod 3 to exchange heat with the core rod 3. The rocker switch 5 is connected in parallel with the metal film resistor 6, and a plug 7 for connecting a socket is provided on the outer shell 1. Mandrel 3 includes a first temperature mode and a second temperature mode. In the first temperature mode, the rocker switch 5 is closed, and the current flows through the cement resistor 4 and the rocker switch 5 in sequence after being input from the pin 7, forming a closed first current path, and heat exchange occurs between the core rod 3 and the cement resistor 4. In the second temperature mode, the rocker switch 5 is disconnected, and the current is input from the pin 7 and flows through the cement resistor 4 and the metal film resistor 6 in sequence to form a closed second current path. Heat exchange occurs between the core rod 3, the cement resistor 4 and the metal film resistor 6.
[0023] Specifically, by setting up a combination of core rod 3, cement resistor 4, metal film resistor 6 and rocker switch 5, two temperature modes are achieved. In different temperature modes, the change in the current path will affect the working power of cement resistor 4 and metal film resistor 6, thereby changing the temperature of core rod 3. This allows users to adjust the evaporation rate of essential oils according to their needs and meet different incense concentration requirements.
[0024] As a preferred option, such as Figure 3 As shown, it also includes a thermal fuse 8, which is connected in series upstream of the cement resistor 4. The thermal fuse 8 is fixedly connected inside the housing 1 and located around the cement resistor 4 and the metal film resistor 6. Specifically, the thermal fuse 8 is connected in series in the circuit, and the temperature sensing part is located around the cement resistor 4 and the metal film resistor 6. It is used to detect overheating and cut off the circuit when the temperature is abnormal to prevent damage to the equipment or cause safety hazards.
[0025] As a preferred option, such as Figure 1 and Figure 3As shown, the outer shell 1 is provided with a limiting rib 101 that matches the cement resistor 4 to fix the position of the cement resistor 4. The outer shell 1 is provided with a first evaporation hole 102, which is located directly above the hot air flow hole 401. Specifically, the limiting rib 101 is used to fix the position of the cement resistor 4 to ensure the stable operation of the heating element. The first evaporation hole 102 is located directly above the hot air flow hole 401, which helps to guide the aroma to diffuse evenly from the heat exchange area to the external space.
[0026] As a preferred option, such as Figure 1 As shown, a second evaporation hole 103 is provided on the outer shell 1. The cross-sectional area of the first evaporation hole 102 is the same as that of the hot air flow hole 401. The second evaporation hole 103 is an oblong hole, which is evenly distributed around the outside of the first evaporation hole 102. Specifically, by adding the second evaporation hole 103 and designing it as an oblong hole, which is evenly distributed around the outside of the first evaporation hole 102, the evaporation area is increased, the diffusion path of the aroma is optimized, and the user's visual experience is also improved.
[0027] As a preferred option, such as Figure 2 and Figure 4 As shown, a plug hole 104 is provided on the side of the outer casing 1. A plug housing 9 is rotatably connected inside the plug hole 104. The plug pin 7 is fixedly connected to the plug housing 9 so that the plug pin 7 can rotate relative to the outer casing 1. Specifically, the plug pin 7 is rotatably connected to the outer casing 1 through the plug housing 9, so that the plug pin 7 can rotate to adapt to the direction of different power sockets, making it convenient for users to install and adjust the angle on the wall, and improving the flexibility of the product.
[0028] As a preferred option, such as Figure 4 As shown, the outer shell 1 is provided with a limiting protrusion 105, and the plug housing 9 is provided with a rotation path 901 and a limiting recess 902. The limiting protrusion 105 can move along the rotation path 901. When the limiting protrusion 105 is located in the limiting recess 902, the plug housing 9 is fixed on the outer shell 1. Specifically, the limiting protrusion 105 is on the outer shell 1, and the rotation path 901 and the limiting recess 902 on the plug housing 9 are used to limit the rotation range of the plug housing 9. When the limiting protrusion 105 is located in the limiting recess 902, the plug housing 9 is locked on the outer shell 1 to ensure that the plug pin 7 will not rotate or fall off accidentally during use.
[0029] In one specific embodiment, such as Figure 4As shown, the limiting protrusion 105 is triangular in shape, with a chamfered top. The limiting recess 902 includes a rib 100 and an arc-shaped rib 200, which are fixedly connected. The arc-shaped rib is fixedly connected to the rotation path. The rib 100 and the arc-shaped rib 200 together form a triangular recess at the connection position to abut and limit the top of the limiting protrusion 105. The distance D1 from the rotation path 901 to the center of the plug housing 9 is less than the distance D2 from the top of the limiting protrusion 105 to the center of the plug housing 9, ensuring that there is no structural interference between the limiting protrusion 105 and the rotation path 901. The arc-shaped rib 200 is made of elastic material. Specifically, the triangular... The limiting protrusion 105, in the shape of a rib, cooperates with the triangular recess formed by the oblique rib 100 and the arc rib 200 to provide a reliable limiting function. At the same time, the arc rib 200 is made of elastic material, preferably plastic. The top chamfer of the limiting protrusion 105 is designed to be adjusted by rotating the plug housing 9. The chamfer of the limiting protrusion 105 cooperates with the elastic arc rib 200, and the arc rib 200 deforms towards the center of the plug housing 9. When the limiting protrusion 105 passes the arc rib 200, the limiting protrusion 105 reaches the position of the next limiting recess 902 through the rotation path 901, and enters the triangular recess through the arc rib 200 of the next limiting recess 902 to abut and fix itself, thus achieving self-locking.
[0030] As a preferred option, such as Figure 2 and Figure 5 As shown, the outer shell 1 is provided with a petal-shaped clamping arm 106, which is made of elastic material, preferably plastic. The glass bottle 2 is provided with a bottle mouth with annular ribs 201. The end of the petal-shaped arm is provided with a snap-fit protrusion 300, which snaps and fixes with the annular ribs 201 of the bottle mouth to fix the glass bottle 2, thereby placing the core rod 3 on the glass bottle 2 within the hot air flow hole 401. Specifically, the petal-shaped clamping arm 106 is made of elastic material, which can firmly fix the glass bottle 2. The bottle mouth of the glass bottle 2 has annular ribs 201, which cooperate with the snap-fit protrusion 300 at the end of the petal-shaped clamping arm 106 to ensure the stable installation and removal of the glass bottle 2. This ensures that the core rod 3 on the glass bottle 2 is accurately placed within the hot air flow hole 401 of the cement resistor 4 inside the outer shell 1, thereby achieving effective heat transfer and essential oil evaporation.
[0031] In a specific implementation, such as Figure 1 and Figure 6As shown, this utility model is designed as a plug-and-play type. It starts working after the plug 7 is inserted into the socket. The heating power is controlled by adjusting the position of the rocker switch 5, thereby controlling the evaporation rate of the essential oil. Specifically, when the rocker switch 5 is in the first position, the rocker switch 5 is in the open state, and the power is relatively low, with the temperature of the core rod 3 being approximately 75°C. When the rocker switch 5 is in the second position, the rocker switch 5 is in the closed state, and the power is relatively high, with the temperature of the core rod 3 being approximately 85°C. At the same time, the thermal fuse 8 is set to disconnect when the temperature exceeds 130°C to prevent overheating.
[0032] The working principle of this utility model is as follows: When in use, the glass bottle 2 is inserted into the outer shell 1. The annular rib 201 at the bottle mouth engages with the snap-fit protrusion 300 at the end of the petal-shaped clamping arm 106 to achieve quick fixation. The core rod 3 is then inserted into the hot air flow hole 401 of the cement resistor 4 to begin heat conduction. After the plug 7 is inserted into the wall socket, the power is turned on. The working mode is selected by operating the rocker switch 5. The temperature fuse 8 continuously monitors the internal temperature. Once it exceeds the safety threshold (such as 130℃), it will melt immediately and cut off the power. The angle of the plug 7 can be adjusted by rotating the plug housing 9. The limiting protrusion 105 slides relative to the rotating path 901 and is snapped into the limiting recess 902 by the elastic arc rib 200 to achieve angle locking.
[0033] This invention controls the temperature of the core rod 3 through two different current paths, thereby adjusting the evaporation rate of the essential oil. The temperature fuse 8 ensures that the power supply is disconnected in time when the device overheats to prevent damage or safety hazards. Through the porous evaporation structure and optimized evaporation path design, the uniformity and diffusion effect of the aroma are improved, meeting the user's personalized needs for the concentration of incense and realizing flexible control of the concentration of incense.
[0034] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
