Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in this application.
[0032] See also Figures 1 to 4In one embodiment, the present application provides an electronic atomizer, comprising:
[0033] The outer surface of the housing 10 is provided with an air inlet 11 and an air outlet 12;
[0034] The oil storage chamber 20 is provided in the housing 10 and is used to store the aerosol product;
[0035] The ventilation pipe 30 runs through the oil storage chamber 20 and one end is connected to the air outlet 12;
[0036] The atomizing assembly 40 has one end connected to the ventilation pipe 30 and the other end connected to the air outlet 12. The side of the atomizing assembly 40 is provided with an oil inlet hole (not shown);
[0037] The first oil guide body 60 has a U-shaped structure. A portion of the first oil guide body 60 covers the oil inlet hole. The aerosol product in the oil storage chamber 20 penetrates into the first oil guide body 60 and then passes through the oil inlet hole into the atomizer assembly 40.
[0038] The bracket 70 is located in the housing 10 and is provided with a lower oil channel 71. One end of the lower oil channel 71 is connected to the oil storage chamber 20, and the other end is provided with a through hole 72. The through hole 72 is arranged relative to the oil inlet hole and spaced apart. The first oil guide body 60 covers the through hole 72 and the oil inlet hole at the same time.
[0039] The shell 10 can be made of plastic. Furthermore, the shell 10 can be made of transparent plastic, so that the remaining amount of the aerosol product inside the oil storage chamber 20 can be directly observed from the outside, which is convenient for users to replace or add aerosol products even if necessary, and is more convenient to use.
[0040] The air inlet 11 and the air outlet 12 can be circular holes or elliptical holes. There are multiple through holes 72, which are waist-shaped holes and extend vertically.
[0041] The bracket 70 can be made of plastic and positioned below the oil reservoir 20. The first oil guide 60 can be made of a material that facilitates oil conduction, such as cotton fiber. The atomizing assembly 40 is used to heat the aerosol product that enters through the oil inlet, forming an aerosol that is then inhaled through the ventilation conduit 30 and the air outlet 12.
[0042] An embodiment of the ventilation duct 30 is as follows: one end of the ventilation duct 30 and the housing 10 are integrally formed, thereby reducing assembly parts and making the electronic atomizer more convenient to assemble.
[0043] In this way, an independent lower oil channel 71 is provided on the bracket 70, and gas-oil exchange occurs in the lower oil channel 71. In a static state, some bubbles can be gathered in the lower oil channel 71, thereby preventing some gas-oil exchange, slowing down the speed at which the aerosol product enters the atomization assembly 40, and solving the problem of oil leakage of the electronic atomizer during long-term static state.
[0044] See also Figure 2 and Figure 4 In one embodiment, the oil lowering channel 71 extends vertically, and the through hole 72 is provided on a side of the oil lowering channel 71 near the oil inlet. This allows the oil lowering channel 71 to be arranged in parallel with the atomizing assembly 40. With the through hole 72 provided on the side, in a static state, bubbles generated by the gas-oil exchange tend to converge at the through hole 72, slowing the speed at which the aerosol product enters the atomizing assembly 40 and reducing the risk of oil leakage.
[0045] See also Figure 3 and Figure 4 In one embodiment, two pressing portions 73 are provided on the side of the bracket 70 , and the two pressing portions 73 are vertically spaced apart from each other. The bracket 70 and the two pressing portions 73 form a receiving groove 74 , and the first oil guide body 60 is located in the receiving groove 74 .
[0046] The pressing portion 73 can facilitate the installation and positioning of the first oil-conducting body 60, and the abutment between the first oil-conducting body 60 and the atomizing assembly 40 can be pressed to make the connection between the first oil-conducting body 60 and the atomizing assembly 40 more tightly, preventing the first oil-conducting body 60 from being located at the outer edge of the oil inlet hole and the through hole 72 to form a gap, and the abutment of the first oil-conducting body 60 is pressed by the inner wall of the accommodating groove 74 to form a certain pressure, so that the porosity of the part of the first oil-conducting body 60 located between the oil inlet hole and the through hole 72 can be greater than the porosity of the first oil-conducting body 60 where it is pressed, so that the aerosol product in the oil storage chamber 20 mainly penetrates into the interior of the atomizing assembly 40 through the through hole 72, the first oil-conducting body 60, and the oil inlet hole in turn, forming an effective oil lock.
[0047] See also Figure 3 and Figure 4 In one embodiment, the receiving groove 74 is an arc-shaped structure, and the inner wall of the receiving groove 74 is adapted to the outer surface of the first oil-conducting body 60. This makes the bracket 70 fit more closely with the first oil-conducting body 60, prevents the first oil-conducting body 60 from shifting, and makes the overall structure more stable.
[0048] See also Figures 2 to 4 In one embodiment, a first leak-proof groove 75 is provided on the side surface of the bracket 70 and the outer side surface of the pressing portion 73. There may be multiple first leak-proof grooves 75, which are sequentially spaced from top to bottom and arranged horizontally. The first leak-proof grooves 75 can be used to store leaked liquid to prevent it from overflowing, making the electronic atomizer more convenient to use.
[0049] See also Figure 4 In one embodiment, an abutment block 77 is provided in the accommodating groove 74 , and the abutment block 77 abuts against the first oil guiding body 60 .
[0050] The abutment block 77 can be extended laterally, and the edge of the first oil-conducting body 60 can be further pressed by the abutment block 77 to prevent the first oil-conducting body 60 from shifting, thereby making the overall assembly structure of the electronic atomizer more stable.
[0051] See also Figure 2 In one embodiment, the electronic atomizer further includes a first seal 90, which is disposed inside the shell 10. The first seal 90 and a portion of the inner wall of the shell 10 form an oil storage chamber 20. The first seal 90 is provided with a lower oil hole 91 and a mounting hole 92. The lower oil channel 71 is connected to the lower oil hole 91, and one end of the ventilation pipe 30 is placed in the mounting hole 92 and connected to the atomization assembly 40.
[0052] The first seal 90 can be made of silicone or rubber. The ventilation duct 30 is elastically sealed against the inner wall of the mounting hole 92. One end of the atomizer assembly 40 is also elastically sealed against the inner wall of the mounting hole 92. The atomizer assembly 40 is connected to the ventilation duct 30 through the mounting hole 92, making assembly more convenient. The end of the oil lowering channel 71 can also be placed in the oil lowering hole 91 and abutted by an elastic seal, making assembly more convenient.
[0053] See also Figure 4 In one embodiment, the cross-section of the lower oil channel 71 is crescent-shaped. This facilitates the accumulation of bubbles at the two tips of the crescent. When the electronic atomizer is in a stationary state, some bubbles can be collected in the lower oil channel 71, thereby preventing some gas-oil exchange and slowing down the speed at which the aerosol product enters the atomizer assembly 40.
[0054] See also Figure 2 In one embodiment, the electronic atomizer further includes a base 80, which is disposed in the shell 10, and an end of the atomizing assembly 40 away from the ventilation duct 30 is disposed on the base 80. The electronic atomizer further includes a second sealing member 100, which is disposed between the side surface of the base 80 and the inner wall of the shell 10.
[0055] The base 80 can be made of plastic, and the second sealing member 100 can be made of rubber or silicone. The second sealing member 100 elastically abuts against the side of the base 80 and the inner wall of the housing 10 to prevent oil leakage. In one embodiment, the second sealing member 100 can be an annular ring that fits over the outer surface of the base 80. Furthermore, the outer surface of the base 80 can be provided with a mounting groove (not shown), with the inner ring of the annular ring positioned within the mounting groove to facilitate positioning and installation of the annular ring.
[0056] See also Figure 2 In one embodiment, the electronic atomizer further includes a base 110 . The base 110 is disposed at an end of the shell 10 away from the air outlet 12 , and the air inlet 11 is disposed at the base 110 .
[0057] The base 110 may be made of plastic. An opening may be formed at one end of the housing 10 away from the air outlet 12 . The base 110 may be at least partially located in the housing 10 and cover the opening.
[0058] See also Figure 2 In one embodiment, the atomization assembly 40 includes a heating wire 41, a second oil guide body 42, and an atomization tube 43. The oil inlet is provided in the atomization tube 43. The second oil guide body 42 is wrapped around the heating wire 41. The second oil guide body 42 and the heating wire 41 are placed in the atomization tube 43.
[0059] The second oil-conducting body 42 can be made of a material that facilitates oil absorption, such as cotton fiber. The oil inlet is located in the atomizing tube 43. The first oil-conducting body 60 is wrapped around the side of the atomizing tube 43 where the oil inlet is located. Aerosol product entering the atomizing assembly 40 through the oil inlet can penetrate the second oil-conducting body 42 and form an aerosol through heating by the heating wire 41. The atomizing tube 43 can be made of a steel pipe, for example. The two ends of the atomizing tube 43 are connected to the air inlet 11 and the ventilation pipe 30, respectively.
[0060] The present application also proposes an electronic atomization device, comprising a power supply component and an electronic atomizer, wherein the power supply component is used to supply power to the electronic atomizer, and the electronic atomizer is the electronic atomizer described above.
[0061] The power supply component can be a battery, such as a lithium battery, which can make the heating wire 41 in the electronic atomizer generate heat, thereby heating the aerosol product to form an aerosol for people to inhale. Since the electronic atomization device adopts the above-mentioned electronic atomizer, it also has all the beneficial effects brought by the above-mentioned electronic atomizer, which will not be repeated here.
[0062] In specific implementation, the above units or structures can be implemented as independent entities, or can be arbitrarily combined to implement as the same or several entities.
