[0031] See also Figures 1 to 5 In one embodiment, the present application proposes an electronic atomizer, including: a housing 10 , an oil guide 20 , a liquid lowering pipe 30 and a heating component 40 .

[0032] The housing 10 is provided with a liquid storage chamber 11 and a leak-proof chamber 12, and the liquid storage chamber 11 is used to store aerosol products;

[0033] The oil guide member 20 is provided with a first installation channel 221 and a second installation channel 222 at intervals. The end of the oil guide member 20 away from the liquid storage chamber 11 is provided with a through hole 23. The oil guide member 20 is arranged in the anti-leakage chamber 12, and the through hole 23 is connected to the anti-leakage chamber 12.

[0034] The lower liquid pipeline 30 is at least partially disposed in the first installation channel 221, one end of the lower liquid pipeline 30 is connected to the liquid storage chamber 11, and the inner wall of the lower liquid pipeline 30 is provided with a first liquid guide hole 31, which is used to allow the aerosol product to enter the oil guide member 20 through the first liquid guide hole 31 of the lower liquid pipeline 30;

[0035] The heating component 40 is at least partially disposed in the second installation channel 222 . The heating component 40 is provided with a second liquid guide hole 41 for allowing the aerosol product in the oil guide member 20 to enter the heating component 40 through the second liquid guide hole 41 .

[0036] The shell 10 can be made of plastic. In one embodiment, the shell 10 is transparent plastic, so that the remaining amount of the aerosol product in the internal liquid storage chamber 11 and the anti-leakage chamber 12 can be easily observed, and it can be conveniently used to replace or add aerosol products, and prevent the heating component 40 from being damaged due to insufficient supply of aerosol products, making the electronic atomizer more convenient to use. The aerosol product can be smoke oil, etc., and the oil guide 20 can be a cotton material or other material that is convenient for oil conduction. In one embodiment, the oil guide 20 can be an integrated cotton, so that it can be easily processed and assembled, and the oil conduction is also more stable.

[0037] The down liquid pipe 30 may be a metal pipe or a plastic pipe, so that the down liquid pipe 30 can be easily assembled in the first installation channel 221, and the outer wall of the down liquid pipe 30 abuts against the inner wall of the first installation channel 221, so that the aerosol product can enter the down liquid pipe 30 more smoothly; the outer wall of the heating component 40 abuts against the inner wall of the second installation channel 222, so that the assembly of the down liquid pipe 30, the heating component 40 and the oil guide member 20 can be more convenient, and the oil guide member 20 can also guide the oil more smoothly.

[0038] The heating component 40 is provided with a heating wire (not marked) and a core cotton (not marked), and the core cotton is wrapped around the heating wire. The core cotton allows the aerosol product entering through the second liquid guide hole 41 to more evenly penetrate into the heating wire to be heated and atomized.

[0039] The first liquid guide hole 31 can be a circular hole, a square hole or a waist-shaped hole. One embodiment is: the first liquid guide hole 31 is arranged on the side wall of the lower liquid pipe 30, the first liquid guide hole 31 and the second liquid guide hole 41 are arranged opposite each other, and the heating wire can be arranged opposite each other with the second liquid guide hole 41, so that the aerosol product can penetrate into the heating component 40 and be heated to form aerosol more smoothly.

[0040] In this way, the aerosol product in the liquid storage chamber 11 can be introduced into the heating component 40 through the oil guide member 20, and the oil can be locked through the oil guide member 20 to prevent the aerosol product in the liquid storage chamber 11 from infiltrating into the heating component 40 too quickly; and because the oil guide member 20 is arranged in the anti-leakage chamber 12, the oil guide member 20 is connected to the anti-leakage chamber 12 through the through hole 23 away from the liquid storage chamber 11, so that the volume of the anti-leakage chamber 12 can be made larger, and the height of the through hole 23 is also lower than the height of the first liquid guide hole 31, so that the excess aerosol product flowing into the oil guide member 20 can more easily flow into the through hole 23 under the action of gravity. Temporary storage is performed in the leak-proof chamber 12 to prevent excess aerosol products from directly entering the heating component 40 and flowing out of the heating component 40 without being heated and atomized, thereby preventing oil leakage; further, the leak-proof chamber 12 is used to store excess aerosol products to prevent leakage. When the heating component 40 is heated too quickly, such as during continuous inhalation, the aerosol products stored in the leak-proof chamber 12 can be sucked back into the oil guide part 20 through the through hole 23, and then enter the heating component 40 to replenish the oil supply, thereby preventing the heating component 40 from getting stuck, making the electronic atomizer more convenient to use.

[0041] See also Figure 3 and Figure 4In one embodiment, the oil guide member 20 includes a sleeve 21 and oil guide cotton 22. The oil guide cotton 22 is arranged in the sleeve 21, and the oil guide cotton 22 is provided with a first installation channel 221 and a second installation channel 222. The sleeve 21 can be made of metal or plastic. In one embodiment, the sleeve 21 is made of transparent plastic, so that the distribution and residual amount of the aerosol product absorbed by the oil guide cotton 22 in the inner sleeve 21 can be easily observed, which can prevent the heating wire from being stuck due to insufficient oil supply, making the electronic atomizer more convenient to use.

[0042] See also Figure 3 and Figure 4 In one embodiment, the heating component 40 is provided with a pressure relief hole 42, which is located at one end of the heating component 40 close to the liquid storage chamber 11. The electronic atomizer also includes an exhaust channel 81, one end of the exhaust channel 81 is connected to the pressure relief hole 42, and the other end is connected to the oil guide part 20 and the anti-leakage chamber 12.

[0043] There may be multiple pressure relief holes 42, which may be evenly distributed in the heating component 40. The pressure relief holes 42 may be used to relieve pressure in the liquid storage chamber 11 and the anti-leakage chamber 12, thereby ensuring that the air pressure in the liquid storage chamber 11 and the anti-leakage chamber 12 is balanced, which is beneficial to balanced oil conduction, thereby ensuring a balanced oil supply to the aerosol product entering the heating component 40, and making the taste of the electronic atomizer more stable.

[0044] See also Figure 3 and Figure 4 In one embodiment, the electronic atomizer further includes a nozzle 50 and a ventilation duct 51, one end of the ventilation duct 51 is connected to the nozzle 50, and the other end is connected to the heating component 40. The nozzle 50 and the ventilation duct 51 can be designed as an integrally formed structure with the housing 10, thereby simplifying the overall structure of the electronic atomizer and facilitating assembly. Through the ventilation duct 51, the aerosol formed by the heating component 40 heating the aerosol product is sucked out from the nozzle 50, and the pressure relief hole 42 can be indirectly connected to the outside through the ventilation duct 51 and the nozzle 50, which can help to ensure the air pressure balance in the liquid storage chamber 11 and the anti-leakage chamber 12, and balance the oil conduction, so that the taste of the electronic atomizer is more stable.

The first sealing member 60 can be made of silicone, and the ventilation pipe 51 and the heating component 40 can be installed more conveniently through the first sealing member 60, and air or oil leakage can be prevented, making the electronic atomizer more convenient to use.

[0046] See also Figure 3 and Figure 4 In one embodiment, the electronic atomizer further includes a second sealing member 70, which seals the end of the sleeve 21 away from the liquid storage chamber 11. The second sealing member 70 may be made of silicone, and the second sealing member 70 can be used to seal the end of the sleeve 21 away from the liquid storage chamber 11 to prevent oil leakage, thereby making the overall structure of the electronic atomizer simpler and more convenient to assemble.

[0047] See also Figure 3 and Figure 4 In one embodiment, the second sealing member 70 is provided with an oil filling hole 71, and the end of the first mounting channel 221 away from the liquid storage chamber 11 is connected to the oil filling hole 71. When filling oil, the entire electronic atomizer is inverted, and the external oil filling needle is inserted into the oil filling hole 71. Since the oil filling hole 71 is made of silicone material, it can form an elastic seal with the outer surface of the oil filling needle. The oil filling needle can be extended into the liquid storage chamber. Under the action of gravity, the smoke oil first fills the part of the liquid storage chamber 11 close to the cigarette holder, and then fills the entire liquid storage chamber 11. The air in the liquid storage chamber 11 can only be discharged from the first liquid guide hole 31 of the lower liquid pipe 30, and passes through the oil guide cotton 22 and the through hole 23 to reach the leak-proof chamber 12, and finally discharged through the pressure relief hole 42. When the liquid storage chamber 11 is filled, continue to fill oil, and the smoke oil is also pressed into the oil guide cotton 22 through the above path, and wets the core cotton. At this time, the oil injection needle is pulled out and the sealing column (not shown) is covered. The sealing column and the oil injection hole 71 are sealed together, and then suction can be performed without waiting for the core lubrication process again. The core lubrication time can be shortened, and suction is more convenient to use.

[0049] See also Figure 3 and Figure 4 In one embodiment, the electronic atomizer further includes a shell 80 and a bottom cover 90. One end of the shell 80 is connected to the first sealing member 60, and the other end is provided with a leak-proof cavity 12.
