An atomizer and electronic cigarette

Abstract

This utility model relates to an atomizer and electronic cigarette, including a shell, an atomizing component, a base, and a separating sleeve. By setting an air exchange component below the atomizing component, when the e-liquid in the reservoir is consumed, negative pressure is generated in the reservoir requiring air replenishment, or air needs to be expelled due to high temperature or pressure changes during storage, gas flows through the air exchange component, the bottom of the atomizing component, and the wicking hole to connect the reservoir and the atomizing chamber, achieving air replenishment or expulsion. Because the airflow during replenishment or expulsion enters through the bottom of the atomizing component, and the heating area of ​​the atomizing component is usually located in the middle, there is no gurgling sound caused by the airflow affecting the air exchange during inhalation, thus improving the vaping experience. Since the air exchange component is located at the bottom of the atomizing component, away from the heating area, it is not exposed to condensate or impurities generated by heating. During air replenishment, impurities or condensate are not drawn into the reservoir, keeping the e-liquid in the reservoir uncontaminated, thereby maintaining good e-liquid fidelity and vaping flavor.

Description

Technical Field

[0001] This utility model relates to the field of cigarette substitute technology, and in particular to an atomizer and an electronic cigarette. Background Technology

[0002] Electronic atomizing devices are electronic products that mimic cigarettes, atomizing e-liquid into vapor for users to inhale. Due to their similar taste and ease of use to cigarettes, electronic atomizing devices have been rapidly promoted and used.

[0003] Existing electronic atomizing devices generally consist of a battery unit and an atomizer. The atomizer is the vapor-generating part of the device, containing e-liquid that vaporizes at high temperatures to form smoke. The battery unit is the control center and power supply unit of the device. When the atomizer atomizes the e-liquid in the reservoir, the e-liquid is continuously consumed, creating negative pressure within the reservoir. This disrupts the e-liquid supply process, leading to insufficient supply to the atomizing components and resulting in a burnt or unpleasant taste, providing a poor vaping experience for the user.

[0004] To improve the problem of insufficient e-liquid supply, existing atomizers have a ventilation hole at the top of the reservoir to allow air exchange between the reservoir and the outside. However, the airflow during inhalation affects the ventilation hole, which can produce a loud gurgling sound and affect the user experience. In addition, when the ventilation hole is replenished, condensate can be mixed into the reservoir, causing the e-liquid in the reservoir to become contaminated and deteriorate. Utility Model Content

[0005] Therefore, it is necessary to provide an atomizer and e-cigarette that does not produce gurgling noises, does not allow condensate to be drawn back into the reservoir, and provides a good vaping experience to address the above problems.

[0006] An atomizer includes a housing, an atomizing component, and a base. The housing includes a mouthpiece end and an open end, and the base is inserted into the open end. It also includes a dividing sleeve that divides the interior of the housing into an oil storage chamber and an atomizing chamber. The dividing sleeve has an oil guide hole. The atomizing component is disposed within the atomizing chamber and blocks the oil guide hole. The oil storage chamber communicates with the atomizing component via the oil guide hole. The base is provided with a ventilation component located at the bottom of the atomizing chamber, with one end of the ventilation component abutting against one end of the atomizing component. The oil storage chamber communicates with the atomizing chamber via the oil guide hole, the atomizing component, and the ventilation component, which are connected in sequence.

[0007] In one embodiment, the base includes a bottom cover and the ventilation assembly. The bottom cover and the ventilation assembly are respectively provided with a first air inlet and a second air inlet. The ventilation assembly is embedded in the bottom cover. The first air inlet is directly opposite the second air inlet, and the first air inlet and the second air inlet are in communication with the atomizing chamber. The ventilation assembly includes a sealing seat and a ventilation hole disposed on the sealing seat. The sealing seat is embedded in the bottom cover, and its two ends respectively abut against the bottom cover and the atomizing assembly. The ventilation hole is in communication with the oil guide hole and the atomizing chamber.

[0008] In one embodiment, the ventilation assembly further includes a ventilation groove, which is formed at one end of the sealing seat that abuts against the atomizing assembly, and the bottom of the ventilation groove is connected to one end of the ventilation hole.

[0009] In one embodiment, the ventilation assembly further includes an oil storage tank, one end of the ventilation hole protrudes from the bottom of the ventilation tank to form a ring of bosses, the bottom of the ventilation tank and the bosses form the oil storage tank, and the top of the bosses is lower than the top of the ventilation tank.

[0010] In one embodiment, the ventilation assembly further includes an oil suction groove, which is disposed at one end of the sealing seat that abuts against the bottom cover, and the oil suction groove is connected to the other end of the ventilation hole; the oil suction groove is filled with oil-absorbing cotton.

[0011] In one embodiment, the bottom cover is provided with a support platform, the sealing seat abuts against the support platform, and an air gap is provided between the sealing seat and the support platform.

[0012] In one embodiment, both the bottom cover and the sealing seat are made of elastic sealing material, one end of the partition sleeve is inserted into the gap between the bottom cover and the sealing seat, and the bottom cover and the sealing seat respectively abut against and seal the inner wall and outer wall of the partition sleeve.

[0013] In one embodiment, a sealing plug is also included, which is disposed between the nozzle and the oil storage chamber. The sealing plug has a through hole in the middle that connects the atomizing chamber and the nozzle. The other end of the separator sleeve is inserted into the sealing plug, and the sealing plug abuts against the outer wall of the separator sleeve.

[0014] In one embodiment, absorbent cotton is also provided between the sealing plug and the suction nozzle.

[0015] An electronic cigarette includes a battery main unit and the aforementioned atomizer, wherein the battery main unit and the atomizer are adapted together.

[0016] The aforementioned atomizers and electronic cigarettes have at least the following advantages:

[0017] This atomizer and e-cigarette features a ventilation component below the atomizing assembly. When e-liquid is consumed, creating negative pressure in the reservoir and requiring air replenishment, or when high temperatures or pressure changes during storage necessitate air removal, gas flows through the ventilation component, the bottom of the atomizing assembly, and the wicking hole to connect the reservoir and the atomizing chamber, achieving air replenishment or exhaust. Because the airflow during replenishment or exhaust enters through the bottom of the atomizing assembly, and the heating area is typically located in the middle, e-liquid consumption begins in the non-heated middle section. Therefore, the airflow during inhalation does not affect ventilation, eliminating gurgling sounds and improving the vaping experience. Furthermore, because the ventilation component is located at the bottom of the atomizing assembly, away from the heating area, it avoids contact with condensate and impurities generated during heating. Replenishing air prevents impurities or condensate from being drawn into the reservoir, keeping the e-liquid in the reservoir uncontaminated and maintaining good e-liquid fidelity and flavor.

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] Please see Figure 1 This is a schematic diagram of the structure of an electronic cigarette in one embodiment.

[0027] Please see Figures 2-4 The atomizer 10 is an aerosol generator of the electronic atomization device, which is used to generate heat when powered on, so that the e-liquid in the atomizer 10 forms an aerosol for the user to inhale. Specifically, the atomizer 10 includes a housing 12, an atomizing component 14, and a base 16. The housing 12 includes a mouthpiece 122 end and an open end, with the base 16 inserted into the open end. It also includes a dividing sleeve 18, which divides the interior of the housing 12 into an oil storage chamber 124 and an atomizing chamber 126. The dividing sleeve 18 has an oil guide hole 182. The atomizing component 14 is disposed in the atomizing chamber 126 and blocks the oil guide hole 182. The oil storage chamber 124 is connected to the atomizing component 14 through the oil guide hole 182. The base 16 is provided with a ventilation component 164, which is disposed at the bottom of the atomizing chamber 126, with one end of the ventilation component 164 abutting against one end of the atomizing component 14. The oil storage chamber 124 is connected to the atomizing chamber 126 through the oil guide hole 182, the atomizing component 14, and the ventilation component 164 in sequence.

[0028] The atomizer 10 and the electronic cigarette have an air exchange component 164 below the atomizing component 14. When the e-liquid in the oil storage chamber 124 is consumed, when negative pressure is generated in the oil storage chamber 124 and air needs to be replenished, or when high temperature or pressure changes during storage require the air in the oil storage chamber 124 to be expelled, the gas connects the oil storage chamber 124 and the atomizing chamber 126 through the air exchange component 164, the bottom of the atomizing component 14, and the oil guide hole 182, thereby achieving air replenishment or exhaust. Because the airflow during replenishment or exhaust enters through the bottom of the atomizing component 14, and the heating area of ​​the atomizing component 14 is usually located in the middle, the consumption of e-liquid in the atomizing component 14 also starts from the non-heating area in the middle. Therefore, the airflow during inhalation will not affect the ventilation, and there will be no gurgling sound, thus improving the vaping experience. In addition, because the ventilation component 164 is located at the bottom of the atomizing component 14, away from the heating area, it is not exposed to condensate or impurities generated by heating. When replenishing air, impurities or condensate will not be drawn into the e-liquid storage chamber 124, thus keeping the e-liquid in the e-liquid storage chamber 124 uncontaminated, thereby maintaining good e-liquid fidelity and vaping taste.

[0029] Please see Figure 2 , Figure 3 In this embodiment, the base 16 includes a bottom cover 162 and a ventilation assembly 164. The bottom cover 162 and the ventilation assembly 164 are respectively provided with a first air inlet 1622 and a second air inlet 1641. The ventilation assembly 164 is embedded in the bottom cover 162. The first air inlet 1622 is directly opposite the second air inlet 1641, and the first air inlet 1622 and the second air inlet 1641 are connected to the atomizing chamber 126. The ventilation assembly 164 includes a sealing seat 1642 and a ventilation hole 1643 provided in the sealing seat 1642. The sealing seat 1642 is embedded in the bottom cover 162, and its two ends respectively abut against the bottom cover 162 and the atomizing assembly 14. The ventilation hole 1643 is connected to the oil guide hole 182 and the atomizing chamber 126. The bottom cover 162 and the sealing seat 1642 can seal the bottom of the oil storage chamber 124, the dividing sleeve 18, and the bottom of the atomizing component 14 to prevent oil leakage. The ventilation hole 1643 can be preset in size according to ventilation requirements to avoid leakage or poor ventilation caused by the ventilation hole being too large or too small. Preferably, the ventilation hole 1643 can be a collection of multiple capillary pores, which, while meeting ventilation requirements, adsorbs e-liquid through capillary adsorption, preventing oil leakage.

[0030] In this embodiment, the ventilation assembly 164 further includes a ventilation groove 1644, which is formed at one end of the sealing seat 1642 that abuts against the atomizing assembly 14, and the bottom of the ventilation groove 1644 is connected to one end of the ventilation hole 1643. The ventilation groove 1644 is recessed in the sealing seat 1642 and located at the bottom of the atomizing assembly 14. The ventilation groove 1644 prevents the ventilation hole 1643 from directly contacting the atomizing assembly 14, forming a suspended space between the atomizing assembly 14 and the ventilation hole 1643. Therefore, during ventilation, the airflow will not carry the e-liquid adsorbed by the atomizing assembly 14 to the ventilation hole 1643, and also avoids the situation where the e-liquid adsorbed by the atomizing assembly 14 flows to the ventilation hole 1643, blocks the ventilation hole 1643, and affects ventilation.

[0031] In this embodiment, the ventilation assembly 164 further includes an oil storage tank 1645. One end of the ventilation hole 1643 protrudes from the bottom of the ventilation tank 1644 to form a raised platform 1646. The bottom of the ventilation tank 1644 and the raised platform 1646 form the oil storage tank 1645, and the top of the raised platform 1646 is lower than the top of the ventilation tank 1644. When a small amount of e-liquid is carried out with the airflow or when a small amount of e-liquid drips due to the saturation of the atomizing assembly 14, the oil storage tank 1645 can store the e-liquid, and the raised platform 1646 can prevent the e-liquid from flowing to the ventilation hole 1643, thus preventing the e-liquid from entering the ventilation hole 1643 and blocking it, thereby affecting ventilation.

[0032] In this embodiment, the ventilation assembly 164 further includes an oil-absorbing groove, which is disposed at one end of the sealing seat 1642 that abuts against the bottom cover 162, and the oil-absorbing groove is connected to the other end of the ventilation hole 1643; the oil-absorbing groove contains oil-absorbing cotton 1647. The oil-absorbing groove and oil-absorbing cotton 1647 are provided at the other end of the ventilation hole 1643 to absorb the e-liquid flowing out of the ventilation hole 1643, preventing e-liquid from accumulating at the end of the ventilation hole 1643 and blocking it, further eliminating the impact of possible oil accumulation on ventilation.

[0033] In this embodiment, the bottom cover 162 is provided with a support platform 1624, the sealing seat 1642 abuts against the support platform 1624, and a ventilation gap 1648 is provided between the sealing seat 1642 and the support platform 1624. Since the airflow required for ventilation is small, a small gap 1648 is sufficient for airflow. Alternatively, a bevel or rounded corner can be cut into the direct structure, eliminating the need for a dedicated air intake space, which simplifies the process and assembly steps.

[0034] Please see Figure 4In this embodiment, both the bottom cover 162 and the sealing seat 1642 are made of elastic sealing material. One end of the separating sleeve 18 is inserted into the gap 1648 between the bottom cover 162 and the sealing seat 1642, and the bottom cover 162 and the sealing seat 1642 respectively abut against the inner wall and outer wall of the sealing separating sleeve 18. The fact that both the bottom cover 162 and the sealing seat 1642 are made of elastic sealing material is beneficial to the sealing between the oil storage chamber 124 and the atomizing chamber 126 and the separating sleeve 18 and the housing 12, avoiding oil and air leakage from the gap 1648 between the components, so that the e-liquid and airflow can be supplied and flow according to the preset route.

[0035] In this embodiment, a sealing plug 128 is also included. The sealing plug 128 is disposed between the mouthpiece 122 and the oil storage chamber 124. A through hole is provided in the middle of the sealing plug 128 to connect the atomizing chamber 126 and the mouthpiece 122. The other end of the separating sleeve 18 is inserted into the sealing plug 128, and the sealing plug 128 abuts against the outer wall of the separating sleeve 18. The sealing plug 128 can seal the gap 1648 between the mouthpiece 122 and the oil storage chamber 124, the separating sleeve 18, and the housing 12, preventing oil and air leakage between the components, so that the e-liquid and airflow can be supplied and flow according to the preset route.

[0036] In this embodiment, an absorbent cotton 129 is also provided between the sealing plug 128 and the mouthpiece 122. The absorbent cotton 129 can absorb the condensate formed when the high-temperature smoke generated by atomization cools down, preventing the condensate from being sucked into the mouth when there is a lot of condensate, which would affect the taste and experience of smoking.

[0037] Please see Figure 1 This application also provides an electronic atomizing device, including a battery main unit 20 and an atomizer 10, wherein the battery main unit 20 and the atomizer 10 are adapted to each other. The specific structure of the atomizer 10 is as described in the above embodiments. Since this electronic atomizing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
