Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to an aerosol generating device. Background Art

[0002] Aerosol generating devices are also known as virtual cigarettes, electronic cigarettes, steam cigarettes, etc. They are mainly used for quitting smoking or replacing cigarettes. Aerosol generating devices heat the tobacco oil to atomize the tobacco oil, and the atomized tobacco oil flows out along the mouthpiece for customers to inhale.

[0003] In the related art, the aerosol generating device includes an oil cup and sealing silicone. An oil storage chamber is provided in the oil cup. The sealing silicone abuts against the inner surface of the oil cup and seals the oil storage chamber. An oil filling hole is provided on the sealing silicone. During the production process of the aerosol generating device, the smoke oil needs to be injected into the oil storage chamber through the oil filling hole by an injection device, and then the oil filling hole is sealed to seal the oil storage chamber.

[0004] However, the area of ​​the oil filling hole is small. During the oil filling process, the automatic oil filling equipment generally adopts the method of inserting a needle tube into the oil filling hole. Before the needle tube is inserted, the needle tube and the oil filling hole must be aligned first. If the alignment is not accurate, the needle tube cannot be inserted into the oil filling hole. The current alignment method is manual alignment, that is, the oil cup is first placed directly below the needle tube, and the oil cup is rotated horizontally until the needle tube is aligned with the oil filling hole, and then the needle tube is manually driven to move until the needle tube is inserted into the oil filling hole, and the smoke oil of the automatic oil filling equipment enters the oil cup through the needle tube; this manual alignment oil filling method is easy to cause deviation between the oil filling hole and the needle tube, making it difficult to insert the needle tube into the oil filling hole, or causing the needle tube to directly hit the outer wall of the oil cup, causing damage to the oil cup or the needle tube.

[0042] The following is a detailed description of an aerosol generating device 100 provided in an embodiment of the present application through a specific embodiment in conjunction with all the drawings in the specification.

[0043] Please refer to Figure 1 and Figure 2In one embodiment of the utility model, an aerosol generating device 100 is disclosed, wherein the nozzle component 30 comprises a shell 10, an oil cup 20, a mounting seat 40, a microphone component 50 and an air guide pipe component 60; the nozzle component 30 comprises a nozzle body 32 and an oil seal 34, the nozzle body 32 is provided with an air suction cavity 3202, the oil seal 34 is installed on the nozzle body 32, and the shell 10 is provided with an air inlet 102; the oil cup 20 is installed in the shell 10, the oil cup 20 is provided with an oil storage cavity 202, and the oil storage cavity 202 runs through one end of the oil cup 20; the mounting seat 40 is installed in the shell 10, the mounting seat 40 is provided with an air inlet channel 402 and a microphone mounting cavity 404 separated from each other; the microphone component 50 is installed in the microphone mounting cavity 404; the air guide pipe component 60 is installed in the mounting seat 40, One end of the tube component 60 is penetrated through the oil cup 20, and the air guide tube component 60 is provided with an atomizing chamber 6242 and an oil inlet hole 6244, and the oil storage chamber 202 is connected with the atomizing chamber 6242 through the oil inlet hole 6244; when the suction nozzle body 32 is disassembled relative to the oil cup 20, an annular gap is provided between the outer surface of the air guide tube component 60 and the cavity wall of the oil storage chamber 202; after the oil storage chamber 202 is filled with oil through the annular gap, the suction nozzle body 32 is connected to the oil cup 20, and the end of the air guide tube component 60 away from the oil cup 20 is penetrated through the oil sealing component 34, and the oil sealing component 34 seals the annular gap between the outer surface of the air guide tube component 60 and the cavity wall of the oil storage chamber 202; the air inlet hole 102 is connected with the suction chamber 3202 through the air inlet channel 402 and the atomizing chamber 6242 in turn, and the microphone mounting chamber 404 is connected with the suction chamber 3202.

[0044] Through the above structure, during the oil filling process, the suction nozzle component 30 and the oil cup 20 are separated from each other, and the oil filling equipment only needs to fill the oil into the oil storage chamber 202 through the annular gap between the outer surface of the air guide pipe component 60 and the cavity wall of the oil storage chamber 202; because the gap between the outer surface of the air guide pipe component 60 and the cavity wall of the oil storage chamber 202 is annular, and thus has a large area, it is easy for the needle of the automation equipment to align with the annular gap between the outer surface of the air guide pipe component 60 and the cavity wall of the oil storage chamber 202 to fill the oil storage chamber 20. After the oil storage chamber 202 is filled with oil, the suction nozzle body 32 is installed on the oil cup 20, so that the oil sealing member 34 seals the annular gap between the outer surface of the air guide pipe component 60 and the cavity wall of the oil storage chamber 202; the aerosol generating device 100 in this embodiment is easy to realize automatic oil filling, which reduces the production cost of the aerosol generating device 100.

[0045] In addition, when the user draws suction from the nozzle body 32, the gas in the microphone mounting chamber 404 will be extracted through the suction chamber 3202, so that the air pressure in the microphone mounting chamber 404 is reduced, and then the microphone component 50 is started; the gas flowing from the air inlet 102 through the atomization chamber 6242 to the suction chamber 3202 does not pass through the microphone mounting chamber 404, and the microphone mounting chamber 404 and the atomization chamber 6242 are independent of each other, so that the smoke in the atomization chamber 6242 is not easy to flow into the microphone mounting chamber 404, and the smoke is not easy to condense on the surface of the microphone component 50, thereby reducing the possibility of damage to the microphone component 50.

[0046] Specifically, in the present embodiment, the shell 10 is a hollow cylinder as a whole; the mounting seat 40 is installed in the shell 10, one end of the air guide pipe component 60 is installed on the mounting seat 40, and the other end of the air guide pipe component 60 is passed through the oil cup 20 and the oil seal 34 and is clamped on the nozzle body 32, so that the shell 10, the mounting seat 40, the air guide pipe component 60 and the nozzle body 32 are relatively fixed; the oil cup 20 includes an outer ring 22, the outer ring 22 is placed between the shell 10 and the nozzle body 32, and one end of the nozzle body 32 facing the shell 10 and one end of the shell 10 facing the nozzle component 30 jointly clamp the outer ring 22, so that the oil cup 20, the nozzle body 32 and the shell 10 are relatively fixed; at the same time, the end of the oil cup 20 away from the nozzle component 30 is inserted into the mounting seat 40; the oil seal 34 is cylindrical.

[0047] In other embodiments, the housing 10 may also be in other shapes, such as a rectangle or a column with an elliptical cross-section; the oil cup 20 may also be installed in the housing 10; the nozzle body 32 may also be installed in the housing 10 by a threaded connection direction; the oil seal 34 may also be in other shapes, such as a cuboid, and the shape of the oil seal 34 may be adapted to the shape of the oil storage chamber 202.

[0048] In some embodiments, a first microphone air passage 90 is provided on the oil cup 20, a second microphone air passage 92 is provided between the inner surface of the nozzle body 32 and the outer surface of the oil cup 20, and the microphone mounting cavity 404 is connected to the suction cavity 3202 via the first microphone air passage 90 and the second microphone air passage 92 in sequence.

[0049] Through the above structure, the first microphone air duct 90 is opened in the oil cup 20, and the second microphone air duct 92 is located between the inner surface of the nozzle body 32 and the outer surface of the oil cup 20, so that the first microphone air duct 90 and the second microphone air duct 92 do not need to be supported by other parts. The first microphone air duct 90 and the second microphone air duct 92 are independent of the atomization chamber 6242, thereby simplifying the structure of the aerosol generating device 100.

[0050] Specifically, there is a gap between the inner surface of the nozzle body 32 and the wall of the oil storage cavity 202. The gap between the inner surface of the nozzle body 32 and the wall of the oil storage cavity 202 is the second microphone air channel 92. One end of the first microphone air channel 90 is connected to the microphone mounting cavity 404, and the other end of the first microphone air channel 90 is connected to the suction cavity 3202 via the second microphone air channel 92.

[0051] In this embodiment, the microphone component 50 is placed in the microphone installation cavity 404 , and the microphone component 50 separates the first microphone air passage 90 from the air inlet 102 , so that the air inlet 102 cannot communicate with the first microphone air passage 90 through the microphone installation cavity 404 .

[0052] In other embodiments, the microphone component 50 may not separate the first microphone air passage 90 from the air inlet 102 ; or a partition may be provided in the microphone installation cavity 404 , and the partition is used to separate the first microphone air passage 90 from the air inlet 102 .

[0053] Please refer to Figure 3 and Figure 4 In some embodiments, the air guide pipe component 60 includes a pipe body 62 and a connecting pipe 64. The pipe body 62 is provided with an atomizing chamber 6242 and an oil inlet hole 6244. One end of the pipe body 62 away from the connecting pipe 64 is installed on the mounting seat 40, and the pipe body 62 is passed through the oil cup 20; the connecting pipe 64 is passed through the oil sealing member 34, one end of the connecting pipe 64 is sleeved on one end of the pipe body 62, and the other end of the connecting pipe 64 is clamped with the nozzle body 32.

[0054] In the present embodiment, a section of the air guide tube component 60 having the atomization chamber 6242 is thicker, and another section of the air guide tube component 60 is thinner, making it difficult to manufacture the air guide tube component 60 when the length is longer; through the above structure, the air guide tube component 60 includes a tube body 62 and a connecting tube 64 connected to each other, and the atomization chamber 6242 is opened in the tube body 62, which simplifies the manufacturing difficulty of the air guide tube component 60.

[0055] Specifically, the connecting tube 64 is sleeved on the tube body 62 along the outer side of the tube body 62, the inner diameter of one end of the tube body 62 facing the connecting tube 64 matches the inner diameter of the connecting tube 64, and the wall thickness of the connecting tube 64 is greater than the wall thickness of the tube body 62. The connecting tube 64 and the central tube can be connected to each other by gluing, welding or clamping.

[0056] In some embodiments, the tube body 62 includes a thick tube section 624 and a thin tube section 622 which are interconnected. The thick tube section 624, the thin tube section 622 and the connecting tube 64 are arranged in sequence along the direction from the oil cup 20 to the suction nozzle component 30. An atomization chamber 6242 and an oil inlet hole 6244 are provided in the thick tube section 624; one end of the connecting tube 64 is sleeved on one end of the thin tube section 622; one end of the oil cup 20 is the upper end, and the connecting tube 64 is located at the upper end of the oil cup 20; the oil sealing member 34 seals the annular gap between the outer surface of the connecting tube 64 and the cavity wall of the oil storage cavity 202; the mounting seat 40 is located at the lower end of the oil cup 20; and the end of the thick tube section 624 which is away from the connecting tube 64 is passed through the lower end of the oil cup 20 and mounted on the mounting seat 40.

[0057] Through the above structure, the cross-sectional area of ​​the thick tube section 624 is larger, and then when the atomizing chamber 6242 is opened in the thick tube section 624, the atomizing chamber 6242 can have a larger area; the diameter of the thin tube section 622 is adapted to the diameter of the connecting tube 64, so that the connecting tube 64 is sleeved on the thin tube section 622. In addition, the tube body 62 is integrally formed during the manufacturing process. The air guide tube component 60 in this embodiment includes the tube body 62 and the connecting tube 64, which reduces the length of the tube body 62. The length of the thin tube section 622 is shorter, and then the connection between the thick tube section 624 and the thin tube section 622 is easy to form, making the tube body 62 more convenient to produce.

[0058] Specifically, the central axis of the thick tube section 624 is in line with the central axis of the thin tube section 622. The end of the thick tube section 624 facing the thin tube section 622 is provided with a truncated cone-shaped constriction, and the constriction is connected to the thin tube section 622. The end of the oil cup 20 away from the suction nozzle component 30 is provided with a protrusion 24, and the end of the mounting seat 40 facing the suction nozzle component 30 is provided with a receiving cavity 406 (see Figure 6 ), the raised portion 24 is inserted into the accommodating cavity 406; a mounting groove 2402 is opened in the raised portion 24, one end of the mounting groove 2402 passes through the cavity wall of the oil storage cavity 202 and is connected with the oil storage cavity 202, and the other end of the mounting groove 2402 passes through the end of the raised portion 24 away from the suction nozzle component 30, and the end of the thick tube section 624 away from the thin tube section 622 is installed in the mounting groove 2402, so that the end of the thick tube section 624 away from the connecting tube 64 is installed on the mounting seat 40.

[0059] In some embodiments, at least two clips 642 are protruded from one end of the connecting tube 64 away from the tube body 62, and the clips 642 are evenly distributed around the central axis of the connecting tube 64. There is a gap between two adjacent clips 642. The clips 642 are snap-fitted to the cavity wall of the suction cavity 3202, and the microphone mounting cavity 404 is connected to the suction cavity 3202 via the gap between the two adjacent clips 642.

[0060] Through the above structure, during the assembly process of the aerosol generating device 100, the outer shell 10, the oil cup 20, the mounting seat 40 and the air guide tube component 60 are first assembled together, and then the tobacco oil is injected into the oil storage chamber 202; finally, the outer shell 10 and the suction nozzle component 30 are spliced ​​together, and during the splicing process, the clamping piece 642 on the connecting tube 64 extends into the air inhalation chamber 3202 and is clamped with the cavity wall of the air inhalation chamber 3202 to complete the assembly.

[0061] In addition, the microphone mounting cavity 404 is connected to the air inhalation cavity 3202 via the gap between two adjacent clamping members 642 , and thus no other channel is required between the air inhalation cavity 3202 and the microphone mounting cavity 404 , thereby simplifying the structure of the aerosol generating device 100 .

[0062] Specifically, in this embodiment, the number of the clamping members 642 is two, and the clamping members 642 are in a sheet-like structure similar to an arc. In other embodiments, the number of the clamping members 642 can also be other numbers, such as three or four; the clamping members 642 can also be in other shapes, such as a cylinder.

[0063] Please refer to Figure 5 In some embodiments, the clamping member 642 includes an elastic arm 6422 and a clamping block 6424, the elastic arm 6422 is connected to one end of the connecting tube 64 away from the air guide tube component 60, the clamping block 6424 is connected to the outer surface of the elastic arm 6422, the clamping block 6424 includes a first clamping surface 64242, and the first clamping surface 64242 faces the connecting tube 64; a clamping ring 322 is protruded from the cavity wall of the suction cavity 3202, the central axis of the clamping ring 322 is colinear with the central axis of the connecting tube 64, the clamping ring 322 includes a second clamping surface 3222, the second clamping surface 3222 faces away from the connecting tube 64, and the first clamping surface 64242 and the second clamping surface 3222 are clamped to each other.

[0064] Through the above structure, when the clamping piece 642 is inserted into the suction chamber 3202, the clamping block 6424 abuts against the clamping ring 322, and the elastic arm 6422 bends in the direction of the central axis of the connecting tube 64 and undergoes elastic deformation, so that the clamping block 6424 avoids the clamping ring 322; when the clamping block 6424 and the clamping ring 322 are offset, the elastic arm 6422 resets, so that the clamping block 6424 moves toward the cavity wall of the suction chamber 3202, and the first clamping surface 64242 and the second clamping surface 3222 are clamped with each other.

[0065] Specifically, the clamp ring 322 is disposed at one end of the air suction chamber 3202 facing the oil storage chamber 202, and the end surface of the clamp ring 322 facing the oil storage chamber 202 is inclined, so that when the clamp block 6424 abuts against the clamp ring 322, the clamp ring 322 applies pressure to the clamp block 6424, so that the elastic arm 6422 is deformed.
