Preferably, the oil seal cover 51 is made of silicone.

Preferably, the top surface of the partition wall 106 is lower than the top surface of the liquid storage bullet 1, leaving room for mounting the liquid storage bullet top cap 102.

Or the top of the liquid storage bin 5 is closed, and the liquid storage bomb 1 can be used only once and cannot be added with atomized liquid.

Further, as shown in fig. 7, a liquid storage bullet top cover 102 is disposed on the top of the liquid storage bullet 1, and the liquid storage bullet top cover 102 is located above the oil seal cover 51. The liquid storage bullet top cover 102 is provided with an air outlet hole 103, the side wall of the liquid storage bullet top cover 102 is provided with an air passing hole 1021, and the air outlet hole 103 is communicated with the air passage 105 through the air passing hole 1021. When the reservoir cap 102 is installed, its air vent faces the air passage 105.

Further, in fig. 3, a liquid guide tube 6 is disposed at the bottom of the liquid storage 5, and the atomized liquid in the liquid storage 5 flows out from the liquid guide tube 6. The liquid guide tube 6 is positioned at the central position of the cross section of the liquid storage bullet 1, the liquid guide tube 6 is in transitional connection with the liquid storage bin 5 through the conical part 52, and the conical part 52 facilitates the atomized liquid in the liquid storage bin 5 to flow into the liquid guide tube 6 quickly.

Further, in fig. 3, the outside of the catheter 6 is wrapped with a check valve 7, a liquid guiding device 8 is embedded inside the check valve 7, and a central hole 81 is arranged in the middle of the liquid guiding device 8.

Referring to fig. 8 to 10, the liquid guiding device 8 corresponds to the heating element 4 in the main body 2, a thimble 9 corresponding to the central hole 81 and used for opening the check valve 7 is further disposed at the bottom of the liquid storage cartridge mounting cavity 3, the thimble 9 can penetrate through the central hole 81 in the middle of the liquid guiding device 8 to open the check valve 7, at this time, the atomized liquid in the liquid storage bin 5 flows to the liquid guiding device 8 through the liquid guiding tube 6, the liquid guiding device 8 can permeate the atomized liquid, and the heating element 4 in the main body 2 generates heat to atomize the atomized liquid to generate smoke.

A battery 15 and a control circuit board 16 are arranged in the main body 2, the battery 15 is used for supplying power to the control circuit board 16, and the control circuit board 16 is electrically connected with the heating component 4 and used for controlling the heating of the heating component.

It can be seen that the atomized liquid in the liquid storage bin 5 can flow downwards only after the one-way valve 7 is opened by the thimble 9, that is, the one-way valve 7 can be opened only when the liquid storage bomb 1 is accurately installed in the main body 2; when the liquid storage bullet 1 is pulled out of the main body 2, the one-way valve 7 is automatically closed, and atomized liquid can be prevented from flowing downwards.

Preferably, the liquid guiding device 8 may be a non-woven fabric, glass wool, microporous ceramic, or the like, and the penetration effect of the atomized liquid is enhanced by selecting a suitable material.

Further, in fig. 3, the space between the tapered portion 52 and the bottom inner wall of the reserve cartridge 1 forms an air guide chamber 107, and the air guide chamber 107 communicates with the air duct 105. Air inlet holes 104 are formed in the inner wall of the bottom of the liquid storage bomb 1, and each air inlet hole 104 extends upwards from the lower end of the inner wall of the bottom of the liquid storage bomb 1 and is communicated with the air guide cavity 107. The atomized liquid is atomized into smoke, and then the smoke passes through the air inlet hole 104, the air guide cavity 107, the air passage 105, the air passing hole 1021 and the air outlet hole 103 in sequence and finally enters the mouth of a user.

As shown in fig. 11, a sealing oil film 71 is disposed inside the check valve 7, and the sealing oil film 71 is located on the bottom surface of the catheter 6. A crack 72 is arranged at the center of the oil sealing film, the crack 72 is closed and sealed in a natural state, the gap is narrow, and liquid leakage is avoided; when the slit 72 is penetrated by the thimble 9, the slits 72 are deformed, the gap between the slits 72 is increased, and the atomized liquid starts to flow down in the liquid guide tube 6. In fig. 11, the slit 72 is cross-shaped, but the slit 72 may also be three-pointed star-shaped, that is, three slits extend from the center of the oil seal film to the edge, and the included angle between two adjacent slits is 120 °; or a plurality of slits, such as four slits (refer to a cross slit), five slits, six slits, etc., may be uniformly extended from the center of the oil sealing film to the edge.

In the present application, the air inlets 104 have more than two, and may be three, four, five, etc. Further, as shown in fig. 12 and 13, preferably, the number of the air inlet holes 104 is three, and the air inlet holes are uniformly distributed along the circumferential direction of the inner wall of the bottom of the liquid storage cartridge 1; namely, the three air inlet holes 104 are uniformly distributed along the circumferential direction of the inner wall of the liquid storage bomb 1 with 120 degrees, and the cross section of each air inlet hole 104 is arc-shaped.

The heating component 4 in the main body 2 generates heat to atomize the atomized liquid in the liquid guiding device 8 to generate smoke, and the smoke enters the air passage 105 from the three air inlet holes 104. Because the three air inlet holes 104 are evenly distributed, the smoke can be more evenly introduced, and the condensate can not be gathered at one air inlet hole 104 but evenly distributed at the three air inlet holes 104, so that the air inlet holes 104 can not generate larger condensation effect, and correspondingly, larger water drops can not be formed to be inhaled into the oral cavity of a human body.

Furthermore, as the liquid guide pipe 6 is fully wrapped by the one-way valve 7, the atomized liquid in the liquid guide pipe 6 cannot leak out of the gap and enter the air passage 105, and a good sealing effect is achieved.

Further, a sealing device 10 is arranged in the liquid storage bin 5, the sealing device 10 is used for sealing the liquid guide tube 6, atomized liquid in the liquid storage bin 5 is prevented from flowing downwards along the liquid guide tube 6, and when the thimble 9 opens the one-way valve 7, the sealing device 10 is also pushed open, so that the sealing device 10 does not seal the liquid guide tube 6 any more.

It can be seen that the sealing means 10 is disposable for sealing the liquid conduit 6, and after the liquid storage bomb 1 is installed in the main body 2 for the first time, the sealing means 10 is pushed open by the thimble 9 and floats in the atomized liquid. When the liquid storage bomb 1 is separated from the main body 2, the sealing device 10 can not play a role of sealing the liquid guide tube 6 any more or can not play a role of sealing completely. For example: when the sealing device 10 is made of metal and the liquid storage bomb 1 is vertically placed, the sealing device 10 naturally falls into the liquid guide pipe 6 to be blocked, and a certain sealing effect is achieved. But this is dependent on the material of the sealing means 10 and the orientation in which the cartridge 1 is placed.

The check valve 7 is different from the sealing device 10, and after the liquid storage bomb 1 is separated from the main body 2, the check valve 7 can continuously seal the liquid storage bomb 1 to prevent the atomized liquid from leaking. Under the normal condition, the user can take out the liquid storage bomb 1 after the atomized liquid is consumed, so that the phenomenon of atomized liquid leakage can not happen. However, this case is not suitable for every user, and when the user wants to take out the cartridge 1 in which the atomized liquid is not consumed, it is necessary to consider whether there is a leak of the atomized liquid. In this application, can effectively solve this problem through above-mentioned check valve 7, no matter whether the atomized liquid in the stock solution bullet 1 is consumed, the stock solution bullet 1 takes out the back and can not lead to the atomized liquid to leak, and the user can take out the stock solution bullet 1 at any time, need not worry the atomized liquid and leak.

It can be seen that, in this application, check valve 7 itself just can play the effect of sealed atomized liquid, can only use check valve 7 to seal atomized liquid, also can increase sealing device 10 in stock solution storehouse 5, further strengthens initial sealed effect.

Preferably, the sealing means 10 is adapted to the catheter 6, the sealing means 10 being in the shape of a sphere when the cross-section of the catheter 6 is circular; when the catheter 6 is square in cross-section, the sealing means 10 is square. The sealing device 10 may also be of other shapes, adapted to the cross-section of the catheter 6. In the present case, the catheter 6 is circular in cross-section and the sealing means 10 is a sphere.
