The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. As used in this specification, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in Figures 1 to 21, the electronic atomizer includes a liquid storage bomb 1 and a main body 2. The main body 2 has a liquid storage bomb installation cavity 3 that partially accommodates the liquid storage bomb 1.

As shown in Figure 3, a liquid storage tank 5 for storing atomized liquid is provided inside the liquid storage bomb 1. The liquid storage tank 5 and the liquid storage bomb 1 are integrally formed, that is, the liquid storage tank 5 and the liquid storage bomb 1 are an integrated structure. Compared with the existing technology in which the liquid storage tank 5 and the liquid storage bomb 1 adopt a split structure, this method improves the utilization rate of the liquid storage bomb 1, saves materials, and eliminates the need to install the liquid storage tank 5.

As shown in FIGS. 4 to 6 , an isolation wall 106 is provided inside the liquid storage bomb 1 . The isolation wall 106 separates the interior of the liquid storage bomb 1 to form independent liquid storage chambers 5 and air passages 105 . In this application, a liquid storage bin 5 is formed between one side of the isolation wall 106 and the inner wall of the liquid storage bomb 1, and an air channel 105 is formed between the other side of the isolation wall 106 and the inner wall of the liquid storage bomb 1. Compared with separately arranging the liquid storage bin 5 and the air channel 105 inside the liquid storage bomb 1, this method is simple, reliable and cost-saving.

Furthermore, the cross-section of the liquid storage tank 5 is a superior arcuate shape, and the cross-section of the air passage 105 is an inferior arcuate shape. The superior arcuate shape here refers to a large semicircle, and the inferior arcuate shape refers to a small semicircle.

Preferably, an oil sealing cover 51 is provided on the top of the liquid storage tank 5. The cross-sectional shape of the oil sealing cover 51 matches the cross-sectional shape of the liquid storage tank 5, and both are in an arcuate shape. The side surface of the oil sealing cover 51 includes a vertical arc surface 511 and a vertical flat surface 512 . An oil cap protrusion 513 is provided on the vertical plane 512, and accordingly, an oil cap slot 1061 is provided on the top of the isolation wall 106. When the oil sealing cap 51 is inserted into the liquid storage tank 5 , the oil cap protrusion 513 is embedded in the oil cap slot 1061 . When the oil sealing cap 51 is to be taken out, the user can pull the oil cap protrusion 513 to facilitate the removal of the oil sealing cap 51 . After the oil sealing cap 51 is opened, atomized liquid can be added to the liquid storage tank 5 to facilitate the reuse of the liquid storage bomb 1 .

Preferably, the oil sealing cap 51 is made of silicone.

Preferably, the top surface of the isolation wall 106 is lower than the top surface of the liquid storage bomb 1, leaving space for installing the top cover 102 of the liquid storage bomb.

Preferably, the top of the liquid storage bin 5 can be provided with an oil filling port or an upwardly extending oil filling pipe for injecting atomized liquid into the liquid storage warehouse 5 instead of using the above-mentioned oil sealing cover 51; the oil filling port or the oil filling pipe passes through the obstruction. The oil plug is closed. When it is necessary to inject oil into the liquid storage tank 5, the oil blocking plug is taken out. The oil filling port or oil filling pipe can also be arranged on the side wall of the liquid storage bomb 1. Or the top of the liquid storage tank 5 is closed, and the liquid storage bomb 1 can only be used once, and atomized liquid cannot be added.

Further, as shown in FIG. 7 , a liquid storage bomb top cover 102 is provided on the top of the liquid storage bomb 1 , and the liquid storage bomb top cover 102 is located above the oil sealing cap 51 . The liquid storage bomb top cover 102 is provided with an air outlet hole 103, and the side wall of the liquid storage bomb top cover 102 is provided with an air outlet hole 1021. The air outlet hole 103 communicates with the air channel 105 through the air outlet hole 1021. When the liquid storage bomb top cover 102 is installed, its air hole faces the air channel 105.

Further, in FIG. 3 , a conduit 6 is provided at the bottom of the liquid storage bin 5 , and the atomized liquid in the liquid storage bin 5 flows out from the conduit 6 . The liquid conduit 6 is located at the center of the cross-section of the liquid storage bomb 1. The liquid conduit 6 and the liquid storage tank 5 are transitionally connected through a tapered portion 52. The tapered portion 52 facilitates the atomization of liquid from the liquid storage tank 5. Quickly flow into the catheter 6.

Further, in FIG. 3 , the outside of the liquid conduit 6 is wrapped with a one-way valve 7 , and a liquid conduction device 8 is embedded inside the one-way valve 7 . A central hole 81 is provided in the middle of the liquid conduction device 8 .

With reference to Figures 8 to 10, the liquid guide device 8 corresponds to the heating component 4 in the main body 2, and is also provided at the bottom of the liquid storage bomb installation cavity 3 corresponding to the center hole 81 for opening the one-way valve 7. The thimble 9 can pass through the central hole 81 in the middle of the liquid guide device 8 to open the one-way valve 7. At this time, the atomized liquid in the liquid storage bin 5 flows through the liquid guide tube 6 to the liquid guide device 8, and the liquid guide The device 8 can penetrate the atomized liquid, and the heating component 4 in the main body 2 generates heat to atomize the atomized liquid to generate smoke.

The main body 2 is provided with a battery 15 and a control circuit board 16. The battery 15 is used to supply power to the control circuit board 16. The control circuit board 16 is electrically connected to the heating component 4 and is used to control the heating of the heating component.

It can be seen that only after the one-way valve 7 is opened by the ejector pin 9, the atomized liquid in the liquid storage tank 5 will flow downward. That is, when the liquid storage bomb 1 is accurately installed inside the main body 2, the one-way valve 7 will will be opened; when the liquid storage bomb 1 is pulled out from the host body 2, the one-way valve 7 automatically closes, which can prevent the atomized liquid from flowing downward.

Preferably, the above-mentioned liquid conducting device 8 can be made of non-woven fabric, glass wool, microporous ceramics, etc., and the penetration effect of the atomized liquid can be enhanced by selecting appropriate materials.

Further, in FIG. 3 , the space between the tapered portion 52 and the bottom inner wall of the liquid storage bomb 1 forms an air guide cavity 107 , and the air guide cavity 107 is connected with the air channel 105 . The inner wall of the bottom of the liquid storage bomb 1 is provided with air inlet holes 104 . Each air inlet 104 extends upward from the lower end of the bottom inner wall of the liquid storage bomb 1 and is connected with the air guide cavity 107 . After the atomized liquid is atomized into smoke, it sequentially passes through the air inlet 104, the air guide chamber 107, the airway 105, the air hole 1021, and the air outlet 103, and finally enters the user's mouth.

As shown in FIG. 11 , an oil sealing film 71 is provided inside the one-way valve 7 , and the oil sealing film 71 is located on the bottom surface of the conduit 6 . There is a crack 72 in the center of the oil sealing film. The crack 72 is closed in a natural state with a narrow gap and no liquid leakage. When the crack 72 is penetrated by the ejector pin 9, it deforms, and the gap between the cracks 72 increases and atomizes. Liquid starts in catheter 6 down flow. In Figure 11, the crack 72 is in the shape of a cross. Of course, the crack 72 can also be in the shape of a three-pointed star, that is, three slits extend from the center of the oil sealing film to the edge, and the angle between the two adjacent slits is 120°; it can also be Multiple gaps extend evenly from the center of the oil sealing film to the edge, such as four gaps (refer to cross-shaped cracks), five gaps, six gaps, etc.

In this application, there are more than two air inlets 104, which may be three, four, five, etc. Further, as shown in Figures 12 and 13, it is preferred that there are three air inlet holes 104, evenly distributed along the circumferential direction of the bottom inner wall of the liquid storage bomb 1; that is, the three air inlet holes 104 are in a 120° angle of the liquid storage bomb 1 The inner wall is evenly distributed in the circumferential direction, and the cross section of the air inlet hole 104 is arc-shaped.

The heating component 4 in the host body 2 generates heat to atomize the atomized liquid in the liquid guide device 8 to generate smoke, and the smoke enters the air passage 105 from the three air inlet holes 104 . Since the three air inlets 104 are evenly distributed, the smoke intake is more balanced, and the condensate will not accumulate in one air inlet 104, but is evenly distributed in the three air inlets 104, so that the air inlet 104 is There will be no large condensation effect, and correspondingly there will be no large water droplets that will be sucked into the human mouth.

Furthermore, since the catheter tube 6 is fully wrapped by the one-way valve 7, the atomized liquid in the catheter tube 6 will not leak from the gap and enter the airway 105, which has a good sealing effect.

Furthermore, a sealing device 10 is also provided in the liquid storage tank 5. The sealing device 10 is used to seal the catheter 6 to prevent the atomized liquid in the liquid storage 5 from flowing downward along the catheter 6. When the thimble 9 opens the single When the valve 7 is moved, the sealing device 10 will also be pushed open, so that the sealing device 10 no longer seals the catheter 6 .

It can be seen that the sealing of the catheter 6 by the sealing device 10 is one-time. After the liquid storage bomb 1 is installed in the main body 2 for the first time, the sealing device 10 will be pushed open by the ejector pin 9 and float in the atomized liquid. . When the liquid storage bomb 1 is separated from the main body 2, the sealing device 10 no longer seals the liquid conduit 6, or cannot completely seal the liquid conduit 6. For example: when the material of the sealing device 10 is metal and the liquid storage bomb 1 is placed vertically, the sealing device 10 will naturally fall into the conduit 6 and block it, thereby achieving a certain sealing effect. However, this method is related to the material of the sealing device 10 and the placement direction of the liquid storage bomb 1 .

The one-way valve 7 is different from the sealing device 10. When the liquid storage bomb 1 is separated from the main body 2, the one-way valve 7 can continuously seal the liquid storage bomb 1 to prevent the leakage of atomized liquid. Normally, the user will take out the liquid storage bomb 1 after the atomized liquid is consumed, so that there will be no leakage of the atomized liquid. However, this situation does not apply to every user. When the user wants to take out the liquid storage cartridge 1 with unused atomized liquid, he needs to consider whether the atomized liquid will leak. In this application, the above-mentioned one-way valve 7 can effectively solve this problem. No matter whether the atomized liquid in the liquid storage bomb 1 is consumed, the atomized liquid will not leak after the liquid storage bomb 1 is taken out, and the user can Take out the liquid storage bomb 1, there is no need to worry about the leakage of atomized liquid.

It can be seen that in this application, the one-way valve 7 itself can play the role of sealing the atomized liquid. You can only use the one-way valve 7 to seal the atomized liquid, or you can add a sealing device 10 in the liquid storage bin 5 , further enhancing the initial sealing effect.

Preferably, the sealing device 10 is adapted to the catheter 6. When the cross-section of the catheter 6 is circular, the shape of the sealing device 10 is a sphere; when the cross-section of the catheter 6 is square, the sealing device 10 is in the shape of a sphere. The device 10 is a cube. The sealing device 10 may also have other shapes adapted to the cross-section of the catheter 6 . In this application, the cross section of the catheter 6 is circular and the sealing device 10 is a sphere. The material of the sealing device 10 can be metal, glass, silicone, plastic, etc., and can play a sealing role.
