Description

Atomizer and electronic atomization device

Technical Field

The utility model relates to the technical field of electronic atomization, in particular to an atomizer and an electronic atomization device.

Background

Electronic cigarettes and electronic equipment for atomizing substances such as health care drugs and therapeutic drugs can be collectively referred to as electronic atomizing devices, the electronic atomizing devices generally comprise an atomizer for generating aerosol and a battery assembly for providing electric energy for the atomizer, and the atomizer is taken as a core device of the electronic atomizing device and is always the focus of researches of those skilled in the art.

The atomizer on the market at present generally includes casing and atomizing core, is equipped with air current passageway and is used for storing the stock solution chamber of atomizing liquid in the casing, and the atomizing core generally includes interconnect's liquid and heat-generating body, and the atomizing core is installed on air current flow path of air current passageway and is linked together with the stock solution chamber, and wherein, the material of liquid can be the cotton of leading oil, porous ceramic etc. that the heat-generating body can be metal heater, metal heating wire etc.. The atomization process of the atomizer is generally as follows: atomized liquid flows into the area where the liquid guide body is connected with the heating body from the liquid storage cavity, the atomized liquid around the heating body is atomized under the heating action of the heating body to form aerosol which can be sucked by a user, when the user sucks, suction airflow is formed on an airflow circulation path of the airflow channel, the aerosol is taken away when the suction airflow flows through the heating body, and finally the aerosol flows out of an air outlet of the airflow channel along with the suction airflow to an oral cavity of the user to be sucked by the user.

However, the common problems of the atomizers currently on the market are: because the atomizer can pack the atomized liquid in the liquid storage cavity of the atomizer in advance before sales, after the liquid storage cavity of the atomizer finishes the filling of the atomized liquid on the ground, the air pressure in the liquid storage cavity is approximately the same as the air pressure on the ground (generally, standard atmospheric pressure), and the atomized liquid in the liquid storage cavity can not overflow at the moment, and the atomizer can be in a negative pressure environment (for example, air transportation, the air pressure of the high air is generally 0.7 standard atmospheric pressure), in the negative pressure environment, the air pressure of the external environment is small, and the air pressure in the liquid storage cavity is large, so that the atomized liquid in the liquid storage cavity can accelerate to flow to the atomized core under the action of the internal and external air pressure difference, the atomized liquid can be leaked out from the atomized core easily, and the problem of liquid leakage is caused.

In the related art, in order to reduce the risk of liquid leakage of the atomizer, some factories can plug in a liquid storage cavity with a liquid storage body made of porous materials (for example, fiber cotton is filled in the liquid storage cavity), the liquid storage body is utilized to absorb the atomized liquid in the liquid storage cavity, as the liquid storage body can reduce the fluidity of the atomized liquid, the flow rate of the atomized liquid guided to an atomization core is slowed down, the buffering effect is achieved on the atomized liquid, and therefore the risk of liquid leakage of the atomizer can be reduced to a certain extent by plugging in the liquid storage cavity, however, the applicant finds that in actual use, when the atomizer is in a negative pressure environment for a long time (for example, in a high-altitude transportation state for a long time), even if the liquid storage body is filled in the liquid storage cavity of the atomizer, the problem of liquid leakage still occurs in the atomizer, and the reason is that:

On the one hand, the liquid storage body is of a porous structure with holes, before the atomized liquid is absorbed, air exists in the holes in the liquid storage body inevitably, so that tiny bubbles are remained in the liquid storage body after the atomized liquid is absorbed by the liquid storage body, when the atomizer is in a negative pressure environment for a long time, the air pressure in the liquid storage cavity can be released through relevant structural gaps (such as the communication position between an atomization core and the liquid storage cavity) to be depressurized, the air pressure in the liquid storage cavity and the air pressure of the current external environment tend to be balanced, in the releasing process, the original part of air in the liquid storage cavity can be discharged to the outside through relevant structural gaps, and in an ideal state, if the atomized liquid in the liquid storage cavity is completely absorbed by the liquid storage body at the moment, the atomized liquid is difficult to overflow to the outside through relevant structural gaps, however, after the air pressure in the liquid storage cavity is reduced, a part of the air bubble after expansion can escape from the liquid storage cavity, so that the air pressure in the liquid storage cavity can be increased, the air pressure in the liquid storage cavity can be further expanded, and the atomized liquid can not be further extruded from the liquid storage cavity to the outside due to the fact that the air pressure in the liquid storage cavity is further expanded, and the residual air pressure in the liquid storage cavity can be further expanded;

On the other hand, as the air pressure is lower, the solubility of the air is lower, so that after the air pressure in the liquid storage cavity is reduced, the air originally dissolved in the atomized liquid is separated out of the atomized liquid (particularly separated out in the form of bubbles) due to the reduced solubility, so that the gas content in the liquid storage cavity is further increased, and the air pressure in the liquid storage cavity is further increased;

therefore, the air pressure balance between the liquid storage cavity and the external environment can be broken again, namely, the air pressure in the liquid storage cavity is larger than the air pressure of the current external environment again, so that atomized liquid overflowed from the liquid storage body to the liquid storage cavity can flow to the atomized core and leak from the atomized core under the action of the pressure difference between the internal air pressure and the external air pressure, and the problem of liquid leakage is caused.

Therefore, how to more effectively reduce the risk of leakage of the atomizer is a technical problem to be solved by those skilled in the art.

Referring to fig. 1 to 3, an embodiment of the present utility model provides an atomizer comprising a housing assembly 1, an atomizing core 2, and a liquid reservoir 3 made of a porous material, wherein:

The inside of the shell component 1 is provided with a liquid storage cavity 101, an air flow channel 103 communicated with the outside and at least one exhaust channel 102 communicated with the liquid storage cavity 101, one end of the shell component 1 is provided with a suction nozzle 14 communicated with the air flow channel 103, the liquid storage cavity 101 is provided with a first cavity wall 171 adjacent to the air flow channel 103, and the first cavity wall 171 of the liquid storage cavity 101 is provided with at least one liquid through hole 172;

the atomizing core 2 is arranged in the shell assembly 1 and positioned on the airflow path of the airflow channel 103, and the outer wall of the atomizing core 2 shields each liquid passing hole 172 positioned on the first cavity wall 171;

the liquid storage 3 is arranged in the liquid storage cavity 101, the liquid storage 3 is provided with a first channel 31 and at least one air guide channel 32, each air guide channel 32 is communicated with the outside through an air exhaust channel 102, the air guide channel 32 comprises at least one first air guide groove 321 communicated with the air exhaust channel 102, the first channel 31 extends from one end face of the liquid storage 3, which is close to the suction nozzle 14, to one end face of the liquid storage 3, which is far away from the suction nozzle 14, and penetrates through the liquid storage 3, a part of the inner wall of the first channel 31 is in close contact with a first cavity wall 171 of the liquid storage cavity 101 and shields each liquid through hole 172, so that the liquid storage 3 can supply atomized liquid to the atomization core 2 through the liquid through holes 172 for heating atomization; another portion of the inner wall of the first channel 31 is spaced apart from the first chamber wall 171 and forms at least one first air guide groove 321.

In this embodiment, in the specific implementation, the material of the liquid storage body 3 may be cotton fiber, or may be blend fiber, or may be porous polymer material, and of course, the material of the liquid storage body 3 may also be other types of porous materials, as long as the use requirements of absorbing the atomized liquid and transmitting the absorbed atomized liquid to the atomizing core 2 can be met, that is, as long as the liquid storage body 3 has the functions of absorbing liquid and guiding liquid, which is not limited in this embodiment.

In this embodiment, it should be noted that, in the implementation, in order to form at least one first air guide groove 321 between the inner wall of the first channel 31 and the first cavity wall 171 of the liquid storage cavity 101, the cross-sectional shape of the first channel 31 may be set to be different from the cross-sectional shape of the first cavity wall 171, for example, assuming that the cross-sectional shape of the first cavity wall 171 is circular, the cross-sectional shape of the first channel 31 may be set to be square (such as rectangular or square), triangular, elliptical, trapezoidal, or the like. For example, as shown in fig. 6 and 9, assuming that the cross-sectional shape of the first chamber wall 171 is circular, the cross-sectional shape of the first passage 31 may be set to be square, and four first air guide grooves 321 may be formed between the inner wall of the first passage 31 and the first chamber wall 171 of the liquid storage chamber 101. For another example, to facilitate forming at least one first air guide groove 321 between the inner wall of the first channel 31 and the first cavity wall 171 of the liquid storage cavity 101, it may also be implemented by performing the following structural design on the first channel 31 (in this case, the cross-sectional shape of the first channel 31 is an irregular shape), specifically:

As shown in fig. 10, the first channel 31 includes a mounting channel 311 and at least one ventilation groove 312 communicating with the mounting channel 311, the mounting channel 311 and each ventilation groove 312 extend from an end face of the liquid storage body 3 near the suction nozzle 14 toward an end face of the liquid storage body 3 far from the suction nozzle 14 and penetrate the liquid storage body 3, an inner wall of the mounting channel 311 is in close contact with the first cavity wall 171 of the liquid storage cavity 101 and shields the respective through-liquid holes 172, and an inner wall of the ventilation groove 312 is spaced from the first cavity wall 171 and forms a first air guide groove 321.

In the present embodiment, since a portion of the inner wall of the first channel 31 is spaced from the first cavity wall 171 of the liquid storage cavity 101 and forms at least one first air guiding groove 321 in communication with the air exhaust channel 102, the arrangement of the first air guiding groove 321 can facilitate the air bubbles in the portion adjacent to the first channel 31 in the liquid storage 3 to escape smoothly, so that the air bubbles in the portion adjacent to the first channel 31 in the liquid storage 3 are prevented from escaping difficultly due to being blocked by the first cavity wall 171 of the liquid storage cavity 101 caused by the complete close contact of the inner wall of the first channel 31 with the first cavity wall 171 of the liquid storage cavity 101, thereby reducing the risk of volumetric expansion of the atomized liquid in the liquid storage 3 due to excessive and untimely escape of the expanded air bubbles in the liquid storage 3, and further facilitating the volumetric expansion of the atomized liquid to leak directly from the through-holes 172 of the first cavity wall 171 into the air flow channel 103, furthermore, even if the atomized liquid overflows from the liquid storage body 3, the overflowed atomized liquid can be temporarily stored in the first air guide groove 321 and cannot leak to the outside directly from the liquid through hole 172, and furthermore, the escaped bubbles can be timely discharged to the outside through the air exhaust channel 102 after being changed into gas, so that the phenomenon that the atomized liquid temporarily stored in the first air guide groove 321 cannot leak due to the fact that the air pressure in the liquid storage cavity 101 is increased again after being reduced due to the generation of the bubbles can be avoided, in addition, after part of the bubbles in the position, adjacent to the first channel 31, in the liquid storage body 3 escapes, the inner space occupied by the bubbles in the liquid storage body 3 can be vacated, and the atomized liquid temporarily stored in the first air guide groove 321 can be absorbed again by the liquid storage body 3, so that the atomized liquid is less prone to leakage. Therefore, the risk of liquid leakage of the atomizer in a negative pressure environment can be effectively reduced.

Further, referring to fig. 1-3 and fig. 5-6, in an exemplary embodiment of the utility model, in order to enable bubbles in the liquid storage body 3 located between the inner wall of the first channel 31 and the outer peripheral sidewall of the liquid storage body 3 to escape smoothly, so as to reduce the risk of liquid leakage of the atomizer in a negative pressure environment, the air guide channel 32 further includes at least one second channel 324 in communication with the air exhaust channel 102, each second channel 324 extends from an end surface of the liquid storage body 3 near the suction nozzle 14 toward an end surface of the liquid storage body 3 far from the suction nozzle 14, and each second channel 324 is located between the outer peripheral sidewall of the liquid storage body 3 and the inner wall of the first channel 31. In the embodiment, the second channel 324 may be a through hole or a blind hole, which may be flexibly set according to practical needs, and this embodiment is not limited in particular, and as shown in fig. 1-2, the second channel 324 is illustratively a through hole. In addition, in the embodiment, the inner diameter of the second channel 324 may be flexibly set according to practical needs, so long as the requirement of use can be met, which is not particularly limited in the embodiment, and optionally, the inner diameter of each second channel 324 is 1 mm-4 mm.

In this embodiment, since at least one second channel 324 which is communicated with the air exhaust channel 102 is disposed at a position between the inner wall of the first channel 31 and the outer peripheral side wall of the liquid storage body 3 in the liquid storage body 3, the arrangement of the second channel 324 can facilitate the smooth escape of bubbles in a position adjacent to the second channel 324 in the liquid storage body 3, thereby further reducing the risk of volume expansion of the atomized liquid in the liquid storage body 3 caused by excessive bubbles which expand in the liquid storage body 3 and cannot escape timely, further being beneficial to further reducing the risk of volume expansion of the atomized liquid and leaking to the outside directly from the liquid through hole 172, and even if the atomized liquid overflows from the liquid storage body 3, the overflowed atomized liquid can be temporarily stored in the second channel 324 instead of directly leaking to the outside from the liquid through hole 172, and the escaped bubbles can be discharged to the outside timely through the air exhaust channel 102 after being changed into gas, thereby avoiding the air pressure in the liquid storage cavity 101 from being temporarily increased again due to the generation of bubbles after being reduced, further reducing the risk of volume expansion of the atomized liquid storage body in the liquid storage body 3 and further being leaked to the outside directly from the liquid through hole 172, and the atomized liquid can not be easily absorbed by the bubbles in the second channel 324 after the atomized liquid in the liquid storage body 3 is temporarily stored in the liquid storage body 3. Therefore, in this embodiment, the second channel 324 is added in the liquid storage body 3, so that the risk of liquid leakage of the atomizer in the negative pressure environment can be further reduced.

In this embodiment, since the outer peripheral side wall of the liquid storage 3 is provided with at least one second air guide groove 322 which is communicated with the air exhaust channel 102, the arrangement of the second air guide groove 322 can facilitate the smooth escape of bubbles in the portion adjacent to the second air guide groove 322 in the liquid storage 3, so that bubbles in the portion adjacent to the outer peripheral side wall of the liquid storage 3 in the liquid storage 3 can be prevented from escaping due to the fact that the outer peripheral side wall of the liquid storage 3 is completely and tightly attached to the cavity wall of the liquid storage cavity 101, the risk of volume expansion of atomized liquid in the liquid storage 3 caused by excessive bubbles expanded in the liquid storage 3 and incapability of escaping in time can be further reduced, and further the risk of the atomized liquid leaking to the outside directly from the position of the liquid passing hole 172 can be further reduced, even if the atomized liquid overflows from the liquid storage 3, the atomized liquid overflows from the position of the liquid storage 3 can be temporarily stored in the second air guide groove 322, the atomized liquid can not leak from the position of the liquid passing hole 172 directly, the position of the atomized liquid can be prevented from being blocked by the cavity wall of the liquid storage cavity 101, and the bubbles in the position adjacent to the second air guide groove 101 can be further reduced, and the air pressure of the atomized liquid can not be absorbed by the air guide groove 322 in the position adjacent to the air guide groove 322 can be further reduced, and the air can be further leaked from the outside. Therefore, in this embodiment, the second air guide groove 322 is additionally formed on the outer peripheral sidewall of the liquid storage 3, so that the risk of liquid leakage of the atomizer in the negative pressure environment can be further reduced.

Further, referring to fig. 1-3 and fig. 5-6, in an exemplary embodiment of the present utility model, the air guide channel 32 further includes at least one third air guide groove 323 that is communicated with the air exhaust channel 102, where the third air guide groove 323 may be formed on an end surface of the liquid storage 3 near the suction nozzle 14, may be formed on an end surface of the liquid storage 3 far from the suction nozzle 14, and may be formed on both end surfaces of the liquid storage 3, and the embodiment is not limited thereto, and as illustrated in fig. 1 and fig. 6, at least one third air guide groove 323 is formed on both end surfaces of the liquid storage 3 near the suction nozzle 14 and on an end surface of the liquid storage 3 far from the suction nozzle 14.

In this embodiment, since the end surface of the liquid storage 3 is provided with at least one third air guide groove 323 which is communicated with the air exhaust channel 102, the arrangement of the third air guide groove 323 can facilitate the smooth escape of bubbles in a portion, adjacent to the third air guide groove 323, of the liquid storage 3, so that bubbles in a portion, adjacent to the end surface of the liquid storage 3, of the liquid storage 3 are prevented from escaping due to the fact that the end surface of the liquid storage 3 is tightly attached to the cavity wall of the liquid storage cavity 101, the risk of volume expansion of atomized liquid in the liquid storage 3 caused by excessive bubbles which expand in the liquid storage 3 and cannot escape in time can be further reduced, and further the risk of the atomized liquid leaking to the outside from the position of the liquid passing through the liquid guide hole 172 can be further reduced. Therefore, in this embodiment, the third air guide groove 323 is added on the end surface of the liquid storage body 3, so that the risk of liquid leakage of the atomizer in the negative pressure environment can be further reduced.

In this embodiment, based on the above structural design, when the atomizer is in the negative pressure environment, the gas in the liquid storage cavity 101 can pass through the liquid-proof ventilation film 4 and the exhaust through hole 1021 to be discharged to the outside, so that the air pressure in the liquid storage cavity 101 can be approximately the same as the air pressure of the outside environment, and thus the risk of liquid leakage of the atomizer in the negative pressure environment due to the fact that the air pressure in the liquid storage cavity 101 is greater than the air pressure in the outside environment can be effectively reduced, wherein the arrangement of the liquid-proof ventilation film 4 can ensure that the gas in the liquid storage cavity 101 can be smoothly discharged to the outside, and the atomized liquid overflowed in the liquid storage 3 can be prevented from submerging the exhaust through hole 1021 to leak to the outside.

In this embodiment, considering that the aerosol generated by the atomizing core 2 has a certain temperature during the process of sucking the aerosol by the user through the atomizer, when the aerosol flows through the suction nozzle 14, the aerosol with a higher temperature contacts with the inner wall of the suction nozzle 14 with a lower temperature to be condensed and condensate is generated on the inner wall of the suction nozzle 14, and when more condensate is accumulated on the inner wall of the suction nozzle 14, the user bites the suction nozzle 14 to suck the condensate easily, so that the sucking taste of the user is reduced.

Based on the above structural design, the working principle of the atomizer of this embodiment is as follows:

when the user bites the suction nozzle 14 to perform suction, an air flow is formed on the air flow path between the suction nozzle 14 and the first air inlet 153 and the air flow path between the suction nozzle 14 and the second air inlet 154, that is, two air flow paths through which air flows are formed inside the atomizer, the first air flow path being: the second airflow path is that the first air inlet hole 153, the first accommodating groove 151, the first air inlet groove 121, the second air inlet groove 122, the first through groove 5211, the second through hole 120, the air passage pipe 17, the first through hole 110, the third through hole 511 and the suction nozzle 14 are as follows: second air intake hole 154 → second through slot 522 → second air intake slot 122 → first through slot 5211 → second through hole 120 → air passage tube 17 → first through hole 110 → third through hole 511 → suction nozzle 14; when the air flow flows through the first accommodating groove 151, the air flow sensor 6 can respond to and trigger the atomizing core 2 to work, the atomizing core 2 can heat and atomize the atomized liquid absorbed by the atomizing core 2 and generate aerosol for the user to inhale, and the aerosol generated by the atomizing core 2 can be taken away when the air flow flows through the atomizing core 2, flows to the suction nozzle 14 along with the air flow, and finally is inhaled by the user. However, it is inevitable that during the suction process of the user, not all of the aerosol is sucked by the user, and some of the aerosol remains in the air outlet channel 1032, and the remaining aerosol is settled along the air outlet channel 1032 and flows back into the air inlet channel 1031 to be condensed to form condensate under the action of its own gravity, and since the second absorbent cotton 52 is interposed between the second cover 12 and the bottom cover 15, during the process of flowing back the remaining aerosol into the air inlet channel 1031, the remaining aerosol is absorbed by the second absorbent cotton 52, and even if some of the remaining aerosol forms condensate in the air inlet channel 1031, the second absorbent cotton 52 can absorb the condensate, so that the risk of generating condensate in the air inlet channel 1031 can be reduced, and the risk of leaking condensate to the outside to pollute the environment due to excessive condensate formed in the air inlet channel 1031 and the condensate contacting the air flow sensor 6 to damage the air flow sensor 6 can be reduced.

Further, when the air outlet channel 102 is indirectly connected to the outside through the air outlet channel 1032, considering that the fragrance of the atomized liquid in the liquid storage cavity 101 (the atomized liquid generally contains volatile substances such as essence) will be emitted to the outside through the air outlet channel 102 and the air outlet channel 1032 during the process of storing and transporting the atomizer, so that the fragrance of the atomized liquid is reduced, and further the sucking taste of the subsequent user during suction will be affected, if the air outlet port of the suction nozzle 14 is plugged directly with an object, although the fragrance of the atomized liquid will not volatilize to the outside, this will result in the problem of leaking liquid in the negative pressure environment caused by the air in the liquid storage cavity 101 being unable to be smoothly discharged to the outside, based on this, please refer to fig. 1-3 and fig. 11, in an exemplary embodiment of the present utility model, when the air outlet channel 102 is indirectly connected to the outside through the air outlet channel 1032, the atomizer further includes the plug 7, the air outlet channel 70 is plugged at the air outlet port of the suction nozzle 14, the air outlet channel 70 is opened on the plug 7, and the air outlet channel 70 is connected to the outside, and the air outlet channel 70 has an inner diameter of 0.0-0.8 mm. By the arrangement, the gas in the liquid storage cavity 101 can be smoothly discharged to the outside through the exhaust channel 102, the air outlet channel 1032 and the air outlet channel 70 in sequence, the risk of liquid leakage of the atomizer in a negative pressure environment due to the fact that the air pressure in the liquid storage cavity 101 is larger than the air pressure in the outside environment is reduced, and the inner diameter of the air outlet channel 70 is smaller than 0.2 mm-0.8 mm, so that the fragrance of the atomized liquid is not easy to be emitted to the outside through the air outlet channel 70, the fragrance loss speed of the atomized liquid can be effectively delayed on the premise that the atomizer is not easy to leak, and the phenomenon that the fragrance of the atomized liquid is too fast to influence the sucking taste of a subsequent user during sucking is avoided.

Correspondingly, referring to fig. 1-11, an embodiment of the present utility model further provides an electronic atomization device, where the electronic atomization device includes a battery assembly 8 and the atomizer in any of the above embodiments, the battery assembly 8 is electrically connected with the airflow sensor 6 and the heating element 22 in the atomizing core 2, respectively, and the battery assembly 8 is illustratively installed in a cavity between an outer wall of the cup 13 and an inner wall of the housing 16. In some specific application scenarios, the battery assembly 8 may specifically include a power supply and a control circuit board, where the power supply may be a lithium battery, a dry battery, or other power supply, the control circuit board is electrically connected to the power supply, the atomizing core 2, and the air flow sensor 6, and when the user bites the suction nozzle 14 to perform suction, the air flow sensor 6 senses that parameters such as air pressure and air flow rate of the environment where the user is located change when the air flow flows through the first accommodating groove 151, and then responds to and sends a suction signal for indicating that the user is currently performing suction to the control circuit board, and when the control circuit board receives the suction signal, the control circuit board controls the power supply to supply power to the atomizing core 2, so that the atomizing core 2 is electrified and heats and vaporizes the atomized liquid absorbed by the user into aerosol for the user to inhale. When the user stops sucking, the air flow in the first accommodating groove 151 becomes small or disappears, the air flow sensor 6 senses the air pressure, the air flow speed and other parameters of the environment where the air flow sensor is located again and then responds to and sends a stop signal for indicating that the current user stops sucking to the control circuit board, when the control circuit board receives the stop signal, the control circuit board controls the power supply to stop supplying power to the atomizing core 2, so that the atomizing core 2 stops working, the work of the atomizer is more intelligent, and better use experience is brought to the user.

In this embodiment, specifically, the electronic atomization device of this embodiment may be an electronic cigarette (in this case, the atomized liquid mentioned in the foregoing embodiment of the present utility model may be aerosol forming substrate of a type such as tobacco tar), and the electronic atomization device of this embodiment has the same technical effects as the foregoing atomizer thanks to the improvement of the foregoing atomizer, and will not be described herein again.
