[0004] For a large-capacity atomizer, due to the large amount of e-liquid that can be pre-stored in the oil tank, the gravity and negative pressure of the e-liquid inside it will be greater, which will cause the e-liquid to leak from the oil guiding hole at the bottom of the oil tank due to the action of gravity and negative pressure, resulting in waste of e-liquid and poor experience. Summary of the Utility Model

[0005] Based on this, it is necessary to provide an atomizer and an electronic atomization device that can avoid the leakage of e-liquid due to the action of gravity and negative pressure and have a good experience.

[0010] In one embodiment, the first housing and the second housing are arranged side by side below the end cap. The air inlet channel, the first liquid storage cavity and the atomization cavity are arranged in a "U" shape.

[0011] In one embodiment, a liquid guiding structure is provided in the first liquid storage cavity.

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the specification of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] Please refer to Figure 1 , which is a schematic structural diagram of the atomizer 1 in an embodiment.

[0029] Please refer to Figures 2 to 5 , the atomizer 1 is an aerosol generating device of an electronic atomization device, which is used to generate heat under the condition of being powered on, so that the e-liquid in the atomizer 1 forms an aerosol for the user to inhale. The atomizer 1 includes a housing 10, an atomization assembly 20, and a base 30. The housing 10 includes a mouthpiece 112 and an open end, and the base 30 is disposed at the open end; the housing 10 includes a first housing 12 and a second housing 13. The interior of the first housing 12 is divided into a first oil storage chamber 122 and an atomization chamber 124 by a partition sleeve 14, and the first oil storage chamber 122 and the atomization chamber 124 are communicated through an oil guiding hole 142 provided on the wall surface of the partition sleeve 14. The atomization assembly 20 is disposed in the atomization chamber 124; the second housing 13 is filled with e-liquid to form a second oil storage chamber 132, and an oil through hole 152 is provided between the first oil storage chamber 122 and the second oil storage chamber 132 for communication, and the oil through hole is close to the mouthpiece 112 end of the housing 10.

[0030] As Figure 4As shown, the atomizer 1 is provided with two oil storage chambers, and an oil passage hole 152 is provided at one end close to the mouthpiece 112 to communicate the first oil storage chamber 122 and the second oil storage chamber 132. An atomization assembly 20 is arranged in the first oil storage chamber 122 to atomize the e-liquid, and the second oil storage chamber 132 supplies e-liquid to the first oil storage chamber 122. On the one hand, the storage capacity of the e-liquid can be increased, which is beneficial to the realization of a large-capacity atomizer 1. On the other hand, pressure division can be achieved through the two oil storage chambers. Compared with the case where e-liquid of the same capacity is placed in a large oil storage chamber, dividing the oil storage chamber into two can reduce the gravity and air pressure of the e-liquid in any one oil storage chamber, and reduce the situation of oil leakage and seepage. At the same time, since the oil passage hole 152 is provided at one end close to the mouthpiece 112, when placed and used normally, the possibility of the e-liquid in the second oil storage chamber 132 entering the first oil storage chamber 122 is small, which is beneficial to maintaining the balance of the e-liquid volume and air pressure in the two oil storage chambers and reducing the risk of liquid leakage.

[0031] Especially for large-capacity atomizers 1, the commonly used capacity of atomizers 1 is usually 2-5 ml. For large-capacity atomizers 1 with a capacity of more than 8 ml, or even more than ten ml, because the weight of the e-liquid itself is greater, the gravity and gas pressure of the e-liquid received at the oil guiding hole 142 close to the bottom of the first oil storage chamber 122 are relatively large, making the e-liquid easy to leak out of the first oil storage chamber 122. In order to reduce or avoid the problem of oil leakage, two oil storage chambers, namely the first oil storage chamber 122 and the second oil storage chamber 132, are provided. A relatively large amount of e-liquid is filled into the two separate oil storage chambers, so that the gravity of the e-liquid at the bottom of the first oil storage chamber 122 and the second oil storage chamber 132 is reduced. At the same time, the gas pressure is also divided into two parts to achieve the effect of pressure division.

[0032] Among them, the atomization assembly 20 usually includes an oil guiding element and a heating element. The oil guiding element is used to absorb and guide out the e-liquid, and the heating element is used to heat and atomize the guided-out e-liquid to form an aerosol for the user to inhale. The oil guiding element can be absorbent cotton, porous ceramics, porous metal, etc. Preferably, the atomization assembly 20 is a vertically arranged atomization core arranged along the axis of the atomization chamber 124. The heating element is arranged in a spiral shape, and the absorbent cotton is wrapped around the heating element. It is convenient for installation. A metal sleeve is also sleeved outside the atomization assembly 20. The atomization assembly 20 is arranged in contact with the inner wall of the metal sleeve, and holes are provided on the wall surface of the metal sleeve to communicate with the oil guiding hole 142.

[0033] Furthermore, please refer to Figure 2 、 Figure 3 There can also be absorbent cotton arranged in the gap between the outer wall of the metal sleeve and the inner wall of the partition sleeve 14, which is convenient for the absorbent cotton to absorb oil from the first oil storage chamber 122 and then supply it to the oil guiding element for atomization.

[0034] Specifically, please refer to Figure 2 、 Figure 3, the housing 10 further includes an end cap 15 and a mouthpiece cover 11. The end cap 15 is disposed at one end of the first housing 12 and the second housing 13 close to the mouthpiece 112, and the oil passage hole 152 penetrates through the end cap 15; the mouthpiece cover 11 is covered on the end cap 15, the mouthpiece 112 is disposed on the mouthpiece cover 11, and the end cap 15 is provided with an air outlet hole 154 communicating the atomization chamber 124 and the mouthpiece 112. That is, the first housing 12 and the second housing 13 are separately disposed, and the two are conducted through the oil passage hole 152 opened in the top end cap 15. Of course, the first housing 12, the second housing 13, and the end cap 15 can also be integrally formed. In another embodiment, the housing 10 can also be partitioned into the first housing 12 and the second housing 13 by providing a partition, and the interiors of the first housing 12 and the second housing 13 are the first oil storage chamber 122 and the second oil storage chamber 132. The oil passage hole 152 is provided in the end cap 15, which is beneficial to better block the flow of e-liquid in the first housing 12 and the second housing 13 during normal use and placement, so that the e-liquid will not easily flow into another cavity.

[0035] Please refer to Figure 2 , Figure 3 , in this embodiment, an air intake passage 134 is further provided in the second housing 13, the second oil storage chamber 132 surrounds the air intake passage 134, the end cap 15 is provided with an air intake hole 156, and the air intake hole 156 communicates one end of the air intake passage 134 with the external air, and the air intake hole 156, the air intake passage 134, the atomization chamber 124, and the mouthpiece 112 are sequentially communicated. That is, the air intake position of the atomizer 1 is close to the mouthpiece 112, and no air intake hole 156 is provided at the bottom of the atomizer 1, so that the atomized condensate or e-liquid will not leak out through the bottom of the atomizer 1, and the condensate will not contact electronic components such as the battery, the main board, and the pneumatic sensor, thus preventing the corrosion and influence of the leaked condensate or e-liquid on the electronic components, and improving the stability and service life of the electronic atomization device.

[0036] Among them, the mouthpiece cover 11 is covered on the end cap 15. When the mouthpiece cover 11 completely covers the end cap 15, a through hole corresponding to the air intake hole 156 provided on the end cap 15 is also provided at the corresponding position of the mouthpiece cover 11 for the air intake hole 156 to communicate with the outside air for air intake.

[0037] Furthermore, the base 30 includes a sealing seat 31 and a bottom cover 32. The sealing seat 31 seals the first oil storage chamber 122 and the second oil storage chamber 132. A first liquid storage chamber 33 is provided between the sealing seat 31 and the bottom cover 32, and the air intake passage 134 and the atomization chamber 124 are communicated through the first liquid storage chamber 33. The condensate that may be formed after the e-liquid is atomized will gather and flow along the wall of the atomization chamber 124 through the atomization assembly 20, and finally drip into the first liquid storage chamber 33 and gather in the first liquid storage chamber 33, avoiding the situation that if the condensate cannot be collected and sucked, it will be sucked to the mouth of the smoker along the wall of the atomization chamber 124, which is beneficial to improving the smoking taste.

[0038] In this embodiment, the first housing 12 and the second housing 13 are arranged side by side below the end cap 15, and the intake passage 134, the first liquid storage cavity 33, and the atomization cavity 124 are arranged in a "U" shape; this is not only beneficial for leak prevention, but also has a regular structure, making processing and assembly simpler.

[0039] Furthermore, a liquid guiding structure 34 is provided in the first liquid storage cavity 33. One end of the liquid guiding structure 34 is located in the first liquid storage cavity 33, and the other end is communicated with the first oil storage cavity 122 to introduce the liquid in the first liquid storage cavity 33 into the first oil storage cavity 122. As the e-liquid in the first liquid storage cavity 33 is heated and atomized by the atomization assembly 20, the condensate accumulated on the wall surface of the atomization cavity 124 or the e-liquid leaked from the atomizer 1 will accumulate in the first liquid storage cavity 33 and then be adsorbed and conducted by the liquid guiding structure 34 to the first oil storage cavity 122 for repeated heating and atomization.

[0040] Specifically, the liquid guiding structure 34 can be a cotton strip or other fiber strips, or can also be a liquid guiding structure 34 such as a capillary pore or a capillary tube. In the embodiment of the present application, a liquid guiding cotton strip is adopted, and the two ends of the liquid guiding cotton strip are respectively connected to the first liquid storage cavity 33 and the first liquid storage cavity 33, so as to introduce the liquid in the first liquid storage cavity 33 into the first liquid storage cavity 33 for reuse.

[0041] Even further, a first liquid absorbing member 35 is provided in the first liquid storage cavity 33, and the liquid guiding structure 34 is in contact with the first liquid absorbing member 35. The first liquid absorbing member 35 can be an oil absorbing cotton, that is, the condensate accumulated in the atomization cavity 124 or the e-liquid leaked from the atomizer 1 will accumulate in the first liquid storage cavity 33 and be absorbed by the first liquid absorbing member 35. Due to the good liquid absorbing ability of the first liquid absorbing member 35, when the atomizer 1 is tilted or inverted, the liquid in the first liquid storage cavity 33 will not flow back to the atomization cavity 124 or the intake passage 134, improving the user experience.

[0042] In this embodiment, a second liquid storage cavity 16 is provided between the end cap 15 and the nozzle cap 11. The air outlet hole 154 protrudes from the end cap 15. A sealing ring 17 and a second liquid absorbing member 18 are arranged in the second liquid storage cavity 16, and both the sealing ring 17 and the second liquid absorbing member 18 surround the air outlet hole 154. The protruding part of the air outlet hole 154 is beneficial to the positioning of the sealing ring 17 and the second liquid absorbing member 18. The sealing ring 17 is beneficial to sealing the gap between the end cap 15 and the nozzle cap 11, ensuring good airtightness of the air flow channel entering the nozzle 112. By providing the second liquid storage cavity 16 and the second liquid absorbing member 18, the condensate formed in the atomization cavity 124 during suction can be absorbed by the second liquid absorbing member 18 near the nozzle 112, preventing the condensate from being sucked into the mouth, which is beneficial to improving the smoking taste and user experience. At the same time, it further guarantees the absorption of condensate by the first liquid absorbing member 35. Since the first liquid absorbing member 35 is at the bottom of the atomization cavity 124, the condensate formed when the atomization component 20 heats and atomizes and meets cold on the wall of the atomization cavity 124 may be sucked to the vicinity of the nozzle 112 due to the suction at the nozzle 112. At this time, the second liquid absorbing member 18 can absorb the condensate here to prevent it from being sucked into the mouth.

[0043] Preferably, a one-way valve is also provided at the oil through hole 152, and the one-way valve allows the e-liquid in the second oil storage cavity 132 to flow into the first oil storage cavity 122. The one-way valve enables the e-liquid to only flow from the second oil storage cavity 132 to the first oil storage cavity 122, and the e-liquid in the first oil storage cavity 122 cannot flow to the second oil storage cavity 132. When the e-liquid in the first oil storage cavity 122 is used, there may be a small amount of contamination. The one-way valve is beneficial to ensuring the cleanliness and hygiene of the e-liquid in the second oil storage cavity 132.

[0044] In this embodiment, both ends of the partition sleeve 14 are respectively fixed to the end cap 15 and the sealing seat 31. The outer wall of the atomization component 20 is coated with oil guide cotton and then placed in the partition sleeve 14. The first oil storage cavity 122, the oil guide hole 142, the oil guide cotton, and the atomization component 20 are communicated in sequence.

[0045] Please refer to Figure 3 、 Figure 5 、 Figure 6 , this application also provides an electronic atomization device, including a battery main body 2 and an atomizer 1, and the battery main body 2 and the atomizer 1 are adapted. The specific structure of the atomizer 1 refers to the above embodiment. Since this electronic atomization device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0046] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not conflict, it should be considered as the scope described in this specification.

[0047] The embodiments described above only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
