[0028] Reference Figures 1 to 10 A new type of exhaust fan includes an exhaust cavity 1, wherein a fan blade 3 is arranged in the exhaust cavity 1, and the exhaust cavity 1 has an exhaust port 11, wherein the exhaust port 11 is provided with an aromatherapy device 2, and the aromatherapy device 2 is used to accommodate aromatherapy substances.

[0029] With the above-mentioned structural arrangement, aromatherapy substances (such as aromatherapy essential oil cotton pads, etc.) can be placed in the aromatherapy device during use. Due to the operation of the fan blades, airflow can flow toward the exhaust port, thereby driving the aromatherapy smell to follow the airflow, so that the room where the exhaust fan of the utility model is installed can be filled with aromatherapy smell, effectively meeting the use needs of consumers and improving the user experience of the product.

[0030] In this embodiment, the aromatherapy device 2 includes an aromatherapy chamber 21 for accommodating aromatherapy substances. The aromatherapy chamber 21 has an air inlet 22 and an air outlet 23, with the air inlet 22 positioned toward the fan blades 3. With this structural arrangement, when the fan blades are operating, air can be blown directly into the aromatherapy chamber through the air inlet and the aromatherapy odor within the chamber can be discharged through the air outlet, facilitating the rapid diffusion of the aromatherapy odor. The structure is simple and the design is rational. The air inlet can be four cross-distributed air inlet slots, and the air outlet can be a plurality of horizontally distributed air outlet slots.

[0031] Furthermore, the aromatherapy device 2 includes a base 24 and a cover 25. The base 24 and the cover 25 are arranged opposite each other to form the aromatherapy chamber 21. The air inlet 22 is arranged on the base 24, and the air outlet 23 is arranged on the cover 25, so that the air inlet 22 and the air outlet 23 are arranged opposite each other. In this way, the air inlet and the air outlet form a convection structure, and the fan blades can blow directly into the air inlet, the aromatherapy chamber, and the air outlet in sequence, which is more conducive to the diffusion of the aromatherapy smell. In addition, by removing the cover, the aromatherapy substance in the aromatherapy chamber can be added or replaced, resulting in a simple structure and convenient use.

[0032] The base 24 is provided with a first engaging portion 241 , and the cover 25 is provided with a second engaging portion 251 . The first engaging portion 241 engages with the second engaging portion 251 to connect the base 24 and the cover 25 .

[0033] Specifically, the first engaging portion 241 is a block, and the second engaging portion 251 is a slot. The block is engaged with the slot to connect the base 24 and the cover 25 , which has a simple structure and convenient connection.

[0034] Furthermore, the base 24 is provided with a mounting side 242, which is provided with an arc-shaped slot 243. The block is provided on the inner wall of the arc-shaped slot 243. Accordingly, the cover 25 extends a slot wall 252 toward the base 24, and the slot is formed between the slot wall 252 and the cover 25. The cover 25 is placed with its slot in the arc-shaped slot 243, and the cover 25 is rotated so that the slot engages with the block. The mounting side is provided around the base, and the mounting side is provided with an arc-shaped slot on both the upper and lower sides of the base. Accordingly, two slot walls are provided, one on the upper and lower sides of the cover. In this way, two blocks and two slots are formed. During use, the cover can be installed or removed by rotating the cover to engage or disengage the slot with the block. The structure is simple, stable, reliable, and easy to use.

[0035] Furthermore, the inner wall of the arc-shaped slot 243 is provided with a positioning block 244, and the slot wall 252 is provided with a positioning groove 253. When the slot engages with the positioning block, the positioning groove 253 engages with the positioning block 244. The cooperation between the positioning block and the positioning groove can determine whether the cover has been rotated to the engaged position, facilitating operation. Furthermore, the slot is provided with a stopper 254 to prevent excessive rotation of the cover.

[0036] In this embodiment, the exhaust port 11 is provided with an exhaust grille 12 , and the base body 24 is integrally formed with the exhaust grille through its mounting side 242 , which has a simple structure and a reasonable design.

[0037] In this embodiment, the fan blade 3 includes a first fan blade 31 and a second fan blade 32, and the first fan blade 31 and the second fan blade 32 are both arranged toward the exhaust port 11. Accordingly, the exhaust grille 12 includes a first partition 121 and a second partition 122, and the first partition 121 is arranged corresponding to the first fan blade 31, and the second partition 122 is arranged corresponding to the second fan blade 32. The double-blade structural setting can maximize the flow effect of the airflow, thereby ensuring the basic function of the exhaust fan. In addition, it can also effectively increase the diffusion speed of the aromatherapy smell, thereby enhancing the user experience of the product. Among them, the first partition and the second partition can be provided with an aromatherapy device to enhance the aromatherapy effect.

[0038] In this embodiment, the control panel is provided with a central button and four peripheral buttons. The central button is provided at the center, and the four peripheral buttons are provided around the central button. The central button is provided with an infrared receiving sensor probe (not shown in the figure). On the one hand, the above structural setting can ensure the aesthetics of the entire appearance of the product; on the other hand, the above structural setting does not require additional position layout and matching mold opening for the infrared receiving sensor probe, which is beneficial to the production and manufacturing of the product. In summary, the above design not only facilitates product assembly and improves production efficiency, reduces production costs, but also ensures product stability.

[0039] The aforementioned buttons can be designed as silicone buttons, and the silicone button mold can be a two-color mold, meaning the center button and the four surrounding buttons have different colors. Furthermore, the center button should be considered for infrared penetration, and generally a light color should be selected; the color of the surrounding buttons is not limited to a specific color.

[0040] The above descriptions provide one or more embodiments in conjunction with the specific content, and do not limit the specific implementation of the present invention to these descriptions. Any similarity or similarity with the methods, structures, etc. of the present invention, or any technical deduction or substitution based on the concept of the present invention, shall be deemed to be within the scope of protection of the present invention.
