[0010] Furthermore, the main body includes a pot body and a pot lid detachably connected to the pot body; a hanging seat is provided on the pot lid; the oil cavity and the spray assembly are disposed on the pot body.

[0011] Furthermore, the kettle body and the kettle lid are connected by a quick-release structure, the kettle body is provided with a no-climb removal opening, and a locking structure is provided inside the no-climb removal opening.

[0032] This application embodiment illustrates a diffuser, including a main body 10. The main body 10 includes an oil cavity 100 and a spray assembly 200 that are interconnected. The spray assembly 200 includes an atomizer 210 and a spray channel 220. The atomizer 210 connects the oil cavity 100 and the spray channel 220. The spray channel 220 has a first nozzle 221 that faces outward and is inclined downward. A second nozzle 300 is provided on the main body 10 opposite to the first nozzle 221. The first nozzle 221 is located on the side of the second nozzle 300 facing inward towards the main body 10, and an oil return passage 110 communicating with the oil cavity 100 is provided between the first nozzle 221 and the second nozzle 300.

[0033] In this embodiment, the main body 10 includes an oil cavity 100 and a spray assembly 200 that are interconnected. The spray assembly 200 atomizes and sprays the liquid in the oil cavity 100. Specifically, the spray assembly 200 includes an atomizer 210 and a spray channel 220. The atomizer 210 connects the oil cavity 100 and the spray channel 220. That is, after the liquid in the oil cavity is atomized by the atomizer 210, the oil mist is sprayed outward from the spray channel 220 towards the outside of the main body 10. Since the spray channel 220 has a first nozzle 221 that faces outward and slopes downward, the oil mist can be sprayed downward after being guided by the first nozzle 221. The downward sprayed fragrance mist can enter the usage environment more quickly, and... The upward spraying method has a higher utilization rate of oil and reduces loss. Furthermore, a second nozzle 300 is provided on the main body 10 opposite to the first nozzle 221. The first nozzle 221 is located on the side of the second nozzle 300 facing the inside of the main body 10. A return oil passage 110 communicating with the oil cavity 100 is provided between the first nozzle 221 and the second nozzle 300. In this way, the droplets from the downward-sloping first nozzle 221 enter the return oil passage 110 between the first nozzle 221 and the second nozzle 300, and flow back to the oil cavity 100 from the return oil passage 110. This not only effectively solves the dripping phenomenon caused by downward-sloping spray, but also effectively improves the utilization rate of oil mist.

[0034] In one alternative embodiment, the inner end of the second nozzle 300 is provided with an inclined chamfer 310, and the end of the inclined chamfer 310 away from the main body 10 is a pointed end.

[0035] In this embodiment, when the oil mist passes from the first nozzle 221 through the second nozzle 300, some small droplets will still accumulate in the second nozzle 300, which will lead to dripping after a long time. Therefore, an inclined chamfer 310 is provided at the inner end of the second nozzle 300, and the end of the inclined chamfer 310 away from the main body 10 is a pointed end. That is, after the droplets condense on the second nozzle 300, they can flow along the inclined surface of the inclined chamfer 310 to the oil return passage 110 and then flow back to the oil chamber, further reducing the dripping phenomenon.

[0036] In one alternative embodiment, the spray duct 220 further includes a mist guiding channel 222 that faces outward from the body 10 and is inclined upward, with the first nozzle 221 connected to the end of the mist guiding channel 222 away from the body 10.

[0037] In this embodiment, there is a section of upwardly inclined mist guiding channel 222 at the connection between the spray channel 220 and the oil cavity 100. This allows large particles in the oil mist to settle onto the surface of the mist guiding channel 222 and flow back into the oil cavity 100, resulting in finer sprayed oil mist and reduced dripping. At the same time, the downwardly inclined first nozzle 221 at the rear end of the spray channel 220 can also guide the downward movement of the oil mist.

[0038] In one alternative implementation, such as Figure 2 As shown, the nozzle 220 is configured as an upwardly inclined pipe, and the outer end of the pipe has a downwardly inclined surface. The first nozzle 221 is opened on the inclined surface, and the droplets from the first nozzle 221 can enter the return oil passage 110.

[0039] In one alternative implementation, such as Figure 7 As shown, the spray channel 220 is configured as an arc-shaped pipe with an upwardly inclined arc segment and a downwardly inclined arc segment. The upwardly inclined arc segment can be understood as the mist guiding channel 222; the downwardly inclined arc segment can be understood as the first nozzle 221. Optionally, the diameter of the arc-shaped pipe gradually decreases from the upwardly inclined arc segment to the downwardly inclined arc segment to ensure spray force.

[0040] In one optional embodiment, there is a gap 320 between the first nozzle 221 and the second nozzle 300; the first end of the oil return passage 110 is connected to the gap 320; the second end of the oil return passage 110 is directly connected to the upper part of the oil chamber 100 or connected to the inner bottom of the oil chamber 100 through a pipe; by setting the gap 320, the oil from the first nozzle 221 can be prevented from flowing to the second nozzle 300, and all the oil will flow back from the gap 320, thereby improving the oil utilization efficiency and reducing losses.

[0041] In one optional embodiment, the oil return passage 110 includes an oil return channel 120 inclined toward the bottom of the oil cavity 100; an annular groove 130 is provided in the main body 10, the annular groove 130 is connected to the lower end of the oil return channel 120, and the annular groove 130 is connected to the bottom of the oil cavity 100 through at least one oil return pipe 140.

[0042] In this embodiment, the oil can be smoothly discharged into the annular groove 130 through the inclined oil return channel 120, and then flow from the annular groove 130 into the oil return pipe 140, and finally return to the bottom of the oil chamber 100. This not only achieves rapid oil return, but also prevents oil mist in the oil chamber 100 from overflowing from the oil return passage 110 due to the oil return pipe 140 being connected to the bottom of the oil chamber 100, thus achieving an oil seal effect.

[0043] In one optional embodiment, the main body 10 includes a pot body 400 and a pot lid 500 detachably connected to the pot body 400; a lifting seat 600 is provided on the pot lid 500; the oil cavity 100 and the spray end of the spray assembly 200 are provided on the pot body 400; in this embodiment, the lifting seat 600 on the pot lid 500 is used to lift the embodiment of this application, and the spray ends of the oil cavity 100 and the spray assembly 200 are both provided on the pot body 400. In this way, the pot lid 500 can be removed to add oil to the oil cavity 100 and to clean or replace the spray end of the spray assembly 200.

[0044] In one optional embodiment, the kettle body 400 and the kettle lid 500 are connected by a quick-release structure, and the kettle body 400 is provided with a no-climb removal port 410, and a locking structure is provided inside the no-climb removal port 410.

[0045] In this embodiment, the kettle body 400 and the kettle lid 500 are connected by a quick-release structure, allowing for rapid disassembly of the two with simple actions. The kettle body 400 is provided with a no-climb removal port 410, and a locking mechanism is provided inside the no-climb removal port 410. The user can insert an object such as a long rod into the no-climb removal port 410 and lock the long rod through the locking mechanism. Since the kettle body 400 and the kettle lid 500 are connected by the quick-release structure, after the locking mechanism locks the long rod, the long rod moves the kettle body 400 in the disassembly direction, thereby unlocking the kettle body 400 and the kettle lid 500. Then, the long rod can be used to bring the kettle body 400 back to the ground for corresponding oiling or cleaning steps. It can be understood that after completing the corresponding operation on the kettle body 400, the long rod can still be used to put the kettle body 400 back onto the kettle lid 500 without the need for climbing stairs or other height-related actions.

[0046] In one alternative implementation, a structural design may be provided at one end of the long rod to enhance the connection force with the locking mechanism, such as providing greater friction or a limiting mechanism.

[0047] In one optional embodiment, the quick-release structure is a rotary disassembly structure. In this case, as long as the long rod is inserted into the locking structure and locked therein, the kettle body 400 can be rotated by rotating the long rod, and the kettle body 400 can be removed. Preferably, since rotation is required, a blocking component that limits each other in the direction of rotation can be provided on the locking structure and / or one end of the long rod, such as a toothed structure, so that the long rod can drive the kettle body 400 to rotate.

[0048] In one alternative embodiment, the locking mechanism can be one or more of a toothed mechanism, an elastic locking mechanism, or a friction locking mechanism, as long as it achieves the purpose of locking the long rod, and is not limited thereto.

[0049] In one optional embodiment, the mounting base 600 includes a mounting rod 610 that passes through the pot body 400 and the pot lid 500, and an air passage 620 is formed inside the mounting rod 610; one end of the air passage 620 is used to connect to the air supply unit; the other end of the air passage 620 connects to the oil chamber 100 and the atomizer 210, the atomizer 210 is set as an atomizing core, the atomizing core is connected to the oil chamber 100 through the oil suction pipe 230, and the mist outlet of the atomizing core is connected to the spray channel 220; optionally, an aircraft plug can be fitted on the outside of the mounting rod 610 for mounting the pot body 400.

[0050] In this embodiment, the air supply unit can be an air pump, which supplies air to the air passage 620. The air passage 620 inputs the air into the oil chamber 110 for pressurization. This air supply structure is compact and conducive to stable air supply. The pressurization causes the oil chamber 110 to deliver oil to the atomizer 210. The atomizer 210 uses the high pressure supplied by the air supply unit to atomize the delivered oil, and finally the mist is emitted from the spray channel 220. The atomizer 210 is set as an atomizing core. The atomization process of the atomizing core is existing technology and will not be described in detail here. Of course, the atomizer 210 can also be selected as other atomization principle components, such as ultrasonic atomization, depending on the situation.

[0051] In one optional embodiment, the atomizer 210 is disposed within the oil chamber 100, and the mist outlet of the atomizer 210 faces the oil chamber 100; the atomizer 210 operates inside the oil chamber 100, resulting in lower noise, and is suitable for use in environments with high requirements for quiet operation; the above-mentioned built-in atomizer structure and external atomizer structure can be selected according to the actual needs of the scenario.

[0052] In one alternative embodiment, the atomizer 210 is located at the connection between the oil chamber 100 and the spray channel 220, and the mist outlet of the atomizer 210 faces the spray channel 220. This design provides a strong spray force, which can better deliver the oil mist downwards, and has less requirement for the overall sealing of the structure.
