Description

Technical Field

The utility model relates to the technical field of electronic atomizers, in particular to a one-way air valve anti-reflux electronic atomizer.

Background

Currently, electronic atomizers are used by numerous users. The inside atomizing core that is provided with of electron atomizer generally, atomizing core can heat the inside liquid aerosol matrix that stores of electron atomizer, and then the atomizing generates aerosol, supplies the user to use. Specifically, the atomizing core is also provided with an air inlet for air to enter the atomizing core and drive the aerosol to move, so that the aerosol can reach an outlet for a user to use. Since the aerosol is generated by heating atomization, it is atomized in a normal state. After the user finishes using, the aerosol in the electronic atomizer is easy to condense, and the aerosol turns into liquid aerosol matrix again and flows back into the atomizing core. The reversed flow aerosol substrate can flow out from an air inlet formed in the atomizing core and leak into other parts in the electronic atomizer, so that the internal electronic components are damaged.

The electronic atomizer is also provided with a microphone, the microphone is a component for inducing airflow flow change in the electronic atomizer, and when the microphone senses the airflow flow change, the microphone can electrify the atomizing core so as to start aerosol generation. When there is no airflow change around the microphone, the energizing of the atomizing core is stopped, and the generation of aerosol is stopped. When a user normally uses the electronic atomizer, the air flow is changed by inhaling, so as to obtain aerosol. However, the user may perform an incorrect operation of blowing, and the airflow variation generated by blowing may also energize the atomizing core to generate aerosol, and the generated aerosol may extend into the electronic atomizer along with the airflow, which may damage the components in the electronic atomizer. Therefore, the existing electronic atomizer is easy to cause the backflow of aerosol matrixes and the air blowing misoperation of users, so that the aerosol matrixes leak to other components or the aerosol is condensed on the internal components, and the internal microphone or other components are damaged.

Referring to fig. 1, as shown in fig. 1, an embodiment of the present utility model provides a one-way air valve anti-reflux electronic atomizer 10, which includes a housing 100, a transfer tank 200, an atomization core 300, a liquid absorbing member 400, a one-way air valve 500, and a microphone 600; the transfer tank 200 is disposed inside the housing 100, and divides the housing 100 into an atomization chamber 110 and an electronic chamber 120; an accommodating portion 210 is provided at an end of the transit tank 200 facing the atomizing chamber 110; the unidirectional air valve 500 is inserted through the inner wall of the accommodating portion 210, and one end of the unidirectional air valve 500 protrudes from the inner wall of the accommodating portion 210; the unidirectional air valve 500 is provided with an air flow channel 510 communicated with the atomization cavity 110 and the electronic cavity 120; one end of the atomizing core 300 provided with an air inlet 310 is disposed in the accommodating portion 210; the liquid absorbing member 400 is disposed in the accommodating part 210 and located between the atomizing core 300 and the one-way air valve 500; the microphone 600 is disposed in the electronic cavity 120 and electrically connected to the atomizing core 300; the air flow channel 510 is rotatably provided with a rotary piece 520 inside; when the air flows from the electronic chamber 120 to the atomizing chamber 110, the rotating plate 520 rotates toward the accommodating part 210, and the air flow channel 510 is opened; the rotating plate 520 seals the air flow channel 510 as air flows from the atomizing chamber 110 to the electronic chamber 120, and the air flow channel 510 is closed.

In this embodiment, referring to fig. 1 and 2, the housing 100 is a surrounding structure with a hollow cavity, and the atomizing core 300, the liquid absorbing member 400, the one-way air valve 500, the transfer tank 200 and the microphone 600 are all disposed inside the housing 100. In the housing 100, a transfer tank 200 is provided in a central portion of the housing 100 to divide the housing 100 into an atomizing chamber 110 and an electronic chamber 120. The atomizing cavity 110 is mainly used for accommodating components such as an atomizing core 300, a liquid absorbing piece 400, a one-way valve and the like; the electronic cavity 120 is mainly used for accommodating electronic components such as the microphone 600. The interior of the housing 100 is partitioned into the atomizing chamber 110 and the electronic chamber 120 by the transfer tank 200, which is advantageous for partitioning the working area and preventing the aerosol and aerosol matrix in the atomizing chamber 110 from entering the electronic chamber 120. Specifically, the transfer tank 200 is further provided with a receiving portion 210, the receiving portion 210 is provided with a groove structure, and the groove is provided toward the atomizing chamber 110, and the atomizing core 300, the liquid absorbing member 400, and the one-way air valve 500 are all provided in the receiving portion 210. The inner wall of the accommodating part 210 is penetrated with a one-way air valve 500, and an air flow channel 510 communicating the atomizing chamber 110 and the electronic chamber 120 is arranged in the one-way air valve 500. When the user performs normal inhalation, the air flow enters the atomizing chamber 110 from the electronic chamber 120 through the air flow channel 510, and the air flow direction is the first direction, and the air enters the atomizing chamber 110 from the electronic chamber 120 through the air flow channel 510. The atomizing core 300 is disposed inside the housing 100, and is mainly used for heating the aerosol substrate to atomize and generate aerosol for a user. The atomizing core 300 is provided with an air inlet 310, and air flows into the atomizing cavity 110 from the air flow channel 510, flows into the air inlet 310, and enters the atomizing core 300 to drive aerosol generated in the atomizing core 300 to move. With the inhalation of the user, the air entering the atomizing core 300 will drive the aerosol inside the atomizing core 300 to a position where the user can use.

A one-way gas valve 500 is provided at the gas flow inlet of the atomizing chamber 110. The unidirectional air valve 500 may be connected to the inner wall of the accommodating portion 210, and the unidirectional air valve 500 is actually disposed through the accommodating portion 210, wherein the air flow channel 510 also penetrates through the inner wall of the accommodating portion 210, and the air flow channel 510 can communicate the atomizing chamber 110 and the electronic chamber 120. The air flow channel 510 is internally provided with a rotatable rotating piece 520, and the rotating piece 520 can automatically open the air flow channel 510 along with air flow under specific use conditions. The one-way air valve 500 is provided as an air valve that can be opened only in one direction, which can be opened and closed by providing a rotary piece 520 that can be rotated by the impact of an air flow, and the rotary piece 520 can be rotated only by the impact of an air flow from outside the atomizing chamber 110. When the user inhales normally, the airflow is in the first direction, and the airflow needs to enter the atomizing chamber 110 from the electronic chamber 120, and then flows through the unidirectional air valve 500 and enters the atomizing chamber 110. Referring to fig. 3, as shown in fig. 3, when the airflow direction is the first direction, the unidirectional air valve 500 is opened by the airflow from the electronic cavity 120, and then opens the airflow channel 510, so that the airflow can smoothly enter the atomizing cavity 110 and enter the atomizing core 300 through the air inlet 310. When the user performs the air blowing misoperation, referring to fig. 2, as shown in fig. 2, the airflow direction is in a second direction, and the second direction is opposite to the first direction. At this time, the air is ejected from the air inlet 310 of the atomizing core 300 and flows back into the air flow channel 510 of the one-way air valve 500. However, at this time, the unidirectional air valve 500 is impacted by the airflow from the direction of the atomizing chamber 110, and the unidirectional opening feature thereof keeps the airflow channel 510 in a closed state, so that the airflow cannot pass through the unidirectional air valve 500, and the aerosol contained in the airflow is prevented from reaching other parts in the electronic chamber 120, and is prevented from condensing in other parts in the electronic chamber 120 and damaging components such as the microphone 600.

The microphone 600 disposed inside the housing 100 is a component capable of sensing air flow change, and is electrically connected to the control circuit board inside the electronic cavity 120, and can control the on/off of the control circuit in the control circuit board. Specifically, when the microphone 600 senses the airflow change, the microphone 600 is turned on, and the control circuit is turned on, so that the atomizing core 300 starts to heat and atomize; when the microphone 600 does not sense the change of the airflow, the microphone 600 will be kept in the off state, and the atomizing core 300 will not be heated and atomized. The microphone 600 is disposed inside the electronic cavity 120 and is communicated with the airflow channel 510 through airflow, and when the airflow direction is the first direction, the unidirectional air valve 500 is opened, the airflow can flow in the electronic cavity 120, the microphone 600 can feel the airflow change and then is opened, and the atomization core 300 immediately starts to atomize and generate aerosol; when the airflow direction is the second direction, the unidirectional air valve 500 is closed, the airflow does not reach the microphone 600, and the aerosol generating device of the aerosol generating device 300 stops generating aerosol. It can be seen that the provision of the one-way air valve 500 also prevents the microphone 600 from being started and thus stopping generating more aerosol when the user blows air, thereby reducing the aerosol blown into the electronic cavity 120.

A liquid suction member 400 is provided inside the receiving portion 210, and the liquid suction member 400 is provided between the one-way air valve 500 and the atomizing core 300. The liquid absorbing member 400 is mainly used for absorbing the back-flowed aerosol substrate, preventing the back-flowed aerosol substrate from leaking to other components not in the housing 100, and further preventing other components from being damaged. In particular, the absorbent member 400 can be manufactured using a material capable of absorbing liquid substances, such as a cotton material. Since one end of the one-way valve 500 protrudes toward the inside of the receiving portion 210, the receiving portion 210 can receive a certain amount of the reversed aerosol substrate, preventing the aerosol substrate from immediately rushing into the one-way valve 500.

In a specific use, after the user stops using the one-way air valve to prevent back flow of the electronic atomizer 10, the aerosol remaining inside the atomizing core 300 is condensed and turned back into a liquid aerosol matrix. The aerosol substrate flows to the air inlet 310 on the atomizing core 300 and out of the air inlet 310 through the air outlet into the container 210. The aerosol matrix will first be absorbed by the wick 400, which is the first anti-reflux structure; the aerosol substrate that is not absorbed by the liquid absorbing member 400 reaches the accommodating portion 210, is temporarily stored in the accommodating portion 210, and is a second anti-reflux structure; when the aerosol substrate that can be accommodated in the accommodating portion 210 reaches the maximum value, the aerosol substrate overflows into the one-way valve 500, and the one-way valve 500 is not opened due to the pressure of the aerosol substrate from the direction of the accommodating portion 210, which is a third anti-reflux structure. By arranging the triple anti-reflux structure, reflux of aerosol matrixes can be effectively prevented, and other components of the unidirectional air valve anti-reflux electronic atomizer 10 are protected.

In one embodiment, referring to fig. 4, the one-way valve 500 further includes a valve body 540; the airflow channel 510 extends through the first and second ends of the valve body 540; the first end of the valve body 540 penetrates through the inner wall of the accommodating part 210 and is located in the electronic cavity 120; the second end of the valve body 540 protrudes toward the atomizing chamber 110; the rotary plate 520 is disposed at a first end of the valve body 540.

In this embodiment, the first end and the second end of the valve body 540 are connected through the air flow channel 510, and the first end of the valve body 540 protrudes toward the electronic cavity 120, while the second end of the valve body 540 protrudes toward the atomizing cavity 110. Meanwhile, the first end of the valve body 540 is further provided with a rotation piece 520, and the rotation piece 520 may be rotated toward the inside of the atomizing chamber 110. By means of the rotary piece 520, when the air flow direction of the unidirectional air valve 500 is the first direction, the rotary piece 520 receives the suction force of the air flow and rotates towards the atomization cavity 110, so that the first end of the valve body 540 enters the open state, and further, the first end and the second end of the valve body 540 are communicated, so that the air flow can enter the atomization cavity 110 through the air flow channel 510, and at the moment, the air flow channel 510 is opened; when the airflow direction is the second direction, the rotating plate 520 is under the pressure of the airflow, and keeps on being covered, and prevents the airflow from entering the valve body 540, and the airflow channel 510 is closed. By providing the rotary piece 520 which can only rotate towards the inside of the atomizing chamber 110, the unidirectional air valve 500 can achieve a good anti-blowing effect, and prevents the aerosol from being blown back to the microphone 600 and other elements, thereby avoiding damage to the microphone 600 and other elements. Meanwhile, the rotating piece 520 is disposed at one end of the valve body 540 far away from the atomizing cavity 110, so that a certain depth of the airflow channel 510 can be formed, and further more counter-current aerosol substrates can be contained, so that the anti-reflux effect is enhanced.

In one embodiment, referring to fig. 6, the unidirectional air valve 500 further includes a rotation shaft 530; the rotary plate 520 is connected to the inner wall of the air flow channel 510 through a rotary shaft 530; one end of the rotation shaft 530 is connected to a side wall of the rotation piece 520, and the other end of the rotation shaft 530 is connected to an inner wall of the air flow channel 510; the rotation shaft 530 is connected to one side of the side wall of the rotation piece 520 near the receiving part 210, and the side wall of the rotation piece 520 abuts against the side wall of the air flow passage 510.

The rotary plate 520 may be configured in a plate-like structure having a certain thickness, and one end of the rotary plate 520 is connected to an inner wall of the air flow channel 510 in the first end of the valve body 540 through a rotation shaft 530, and the rotation shaft 530 is disposed at one side of the one end of the rotary plate 520 near the second end of the valve body 540. Since the rotary piece 520 itself has a thickness, when the rotary piece 520 is in a natural state, a side wall of one end of the rotary piece 520 having the rotary shaft 530 naturally abuts against an inner wall of the air flow passage 510 in the first end of the valve main body 540, and cannot continue to rotate in a direction away from the atomizing chamber 110, but naturally covers the air flow passage 510 in the first end of the valve main body 540 in a natural state.

In an embodiment, referring to fig. 5, the rotating plate 520 includes a first rotating plate 521 and a second rotating plate 522 abutting against the first rotating plate 521; the first rotating piece 521 and the second rotating piece 522 are symmetrically disposed on the inner wall of the airflow channel 510, and the first rotating piece 521 and the second rotating piece 522 are both abutted to the inner wall of the airflow channel 510; when the air flows from the air inlet to the air outlet, the first rotating piece 521 and the second rotating piece 522 are rotated toward the accommodating part 210, and the air flow channel 510 is opened.

In the present embodiment, the rotary blade 520 includes a first rotary blade 521 and a second rotary blade 522 symmetrically disposed. The first rotary piece 521 and the second rotary piece 522 abut against each other and are simultaneously rotated toward the atomizing chamber 110 when receiving the suction force of the air flow. By arranging the first rotating piece 521 and the symmetrical second rotating piece 522 in the air duct, the weight of the rotating piece 520 can be reduced, the air flow suction force required by rotating the rotating piece 520 can be reduced, and the air flow smoothness can be further improved; meanwhile, the pressure is dispersed on the first and second rotary pieces 521 and 522, and the reliability of the rotary piece 520 may be improved.

In an embodiment, referring to fig. 2 and 3, the liquid absorbing member 400 divides the accommodating portion 210 into a tank 211 and a liquid storage tank 212 of the atomizing core 300; the atomization core 300 is arranged in the groove 211 of the atomization core 300, and the one-way air valve 500 is arranged in the liquid storage groove 212; the liquid storage tank 212 is disposed around the outside of the unidirectional air valve 500.

In this embodiment, the liquid absorbing member 400 abuts against the inner wall of the accommodating portion 210, and divides the accommodating portion 210 into two parts, namely, the atomizing core 300 groove 211 and the liquid storage groove 212. The liquid storage tank 212 is formed by enclosing the inner wall of the accommodating portion 210, the outer wall of the liquid absorbing member 400 facing the side of the unidirectional air valve 500, and the outer wall of the unidirectional air valve 500, it can be understood that at least three ends of the liquid absorbing member 400 are all abutted in the inner wall of the atomizing chamber 110 to realize a sealing structure, so as to prevent the liquid storage tank 212 from leaking, and the outer wall of the liquid absorbing member 400 facing the side of the unidirectional air valve 500 is in direct contact with aerosol substrates in the liquid storage tank 212. Meanwhile, the liquid storage tank 212 needs to receive a certain amount of aerosol substrate in a natural state, so the liquid storage tank 212 is a groove-shaped containing structure, in one state, the bottom end of the containing structure of the liquid storage tank 212 is the bottom end of the inner wall of the containing portion 210, and the inner side wall of the containing portion 210 also forms the side wall of the liquid storage tank 212. In one instance, none of the outer walls of the one-way valve 500 at the end of the receiving portion 210 is in contact with the inner wall of the receiving portion 210, and thus the reservoir 212 eventually takes the form of a surrounding one-way valve 500. When the aerosol matrix is absorbed to the limit by the liquid absorbing member 400, the aerosol matrix seeps out of the liquid absorbing member 400 and flows into the liquid storage tank 212; when the reservoir 212 is also held to its limit, aerosol matrix will spill over into the one-way valve 500.

In an embodiment, referring to fig. 2 and 3, the liquid absorbing member 400 is provided with a surrounding portion 410 penetrating through two ends; the surrounding part 410 is sleeved at one end of the atomizing core 300, where the air inlet 310 is provided; the air inlet 310 formed on the atomizing core 300 is disposed opposite to the inner wall of the surrounding portion 410.

In this embodiment, the liquid absorbing member 400 is configured in an annular shape, and the surrounding portion 410 is an annular ring of the annular liquid absorbing member 400. The surrounding portion 410 may be sleeved on the end of the atomizing core 300 provided with the air inlet 310. When the wick 400 is provided with the enclosure 410, a portion of the ring representing the wick 400 is located inside the aerosolization chamber 110, responsible for absorbing aerosol matrix flowing out of the air inlet 310 of the aerosolization core 300 and into the aerosolization chamber 110 via the air flow outlet; another portion is located outside the nebulizing chamber 110 and is responsible for absorbing aerosol matrix flowing in other directions from the air inlet 310 of the nebulizing core 300. By arranging the surrounding part 410, and the air inlet 310 on the atomizing core 300 and the inner wall of the surrounding part 410 are arranged opposite to each other, aerosol matrixes flowing out of the air inlet 310 can be absorbed in any direction, so that the absorption efficiency is improved, and the absorption completeness is ensured.

In an embodiment, referring to fig. 2 and 3, a limiting portion 213 is further disposed inside the housing 100; the limiting part 213 is disposed between the inner wall of the surrounding part 410 and the outer wall of the atomizing core 300, and surrounds the atomizing core 300; a liquid blocking groove 214 is formed between the limiting part 213 and the outer wall of the atomizing core 300.

In this embodiment, the limiting portion 213 may be configured as an annular structure, and the annular limiting portion 213 is disposed on the inner side of the surrounding portion 410 in a protruding manner and located between the outer wall of the atomizing core 300 and the inner wall of the surrounding portion 410. A liquid blocking groove 214 is formed between the limiting portion 213 and one end of the atomizing core 300 where the air inlet 310 is provided, and the liquid blocking groove 214 is formed by surrounding the inner wall of the limiting portion 213, the outer wall of the atomizing core 300 and the bottom end of the inner wall of the accommodating portion 210. When the aerosol matrix generated by condensation flows back from the air inlet 310 of the atomizing core 300, the aerosol matrix will first enter the liquid blocking groove 214, and after the aerosol matrix contained in the liquid blocking groove 214 overflows, the aerosol matrix will overflow to the periphery of the limiting portion 213 and be absorbed by the liquid absorbing member 400. By providing the liquid blocking groove 214, not only can the enclosing part be provided with installation limit, but also the aerosol substrate condensed and reflowed can be temporarily prevented from entering the liquid absorbing piece 400, so that the anti-reflow effect is further enhanced.

In an embodiment, referring to fig. 2 and 3, the one-way air valve 500 is disposed at the bottom end of the inner wall of the accommodating portion 210; the liquid absorbing member 400 is abutted to the bottom end of the inner wall of the accommodating part 210; one end of the unidirectional air valve 500 facing the atomization cavity 110 has a first height opposite to the bottom end of the inner wall of the accommodating part 210; a second height is provided at one end of the liquid absorbing member 400 facing the atomizing chamber 110 and opposite to the bottom end of the inner wall of the accommodating portion 210; the first height is less than the second height.

In this embodiment, the unidirectional air valve 500 and the liquid absorbing member 400 are both disposed at the bottom end of the accommodating portion 210, and the bottom end of the inner wall of the accommodating portion 210 is the end closest to the electronic cavity 120 in the inner wall of the accommodating portion 210. One end of the one-way air valve 500 protrudes from the inner wall of the receiving portion 210, so that both the one-way air valve 500 and the liquid absorbing member 400 have a certain height with respect to the bottom end of the inner wall of the receiving portion 210. Wherein the unidirectional air valve 500 has a first height with respect to the bottom end of the inner wall of the accommodating portion 210, and the liquid absorbing member 400 has a second height with respect to the bottom end of the inner wall of the accommodating portion 210. The first height is smaller than the second height, so that the height of the liquid absorbing member 400 is larger than the one-way valve 500, and therefore, when the back-flowing aerosol substrate cannot be absorbed by the liquid absorbing member 400, the back-flowing aerosol substrate will immediately overflow and enter the airflow channel 510 of the one-way valve 500 to be received by the rotating sheet 520.

In an embodiment, referring to fig. 2 and 3, the electronic cavity 120 is provided with an air inlet 121; the atomization cavity 110 is provided with an aerosol outlet 111; an air inlet 130 is arranged in the shell 100; the aerosol outlet 111 communicates with the other end of the atomizing core 300 remote from the air inlet 310; one end of the air inlet 130 is connected to one end of the air flow channel 510 facing the electronic cavity 120, and is communicated with the air flow channel 510; the other end of the intake duct 130 communicates with the air inlet 121.

In the present embodiment, the air inlet 121 is formed in the electronic cavity 120, the aerosol outlet 111 is formed in the atomizing cavity 110, and the aerosol outlet 111 is in communication with the atomizing core 300. Furthermore, when the user inhales normally and uses the one-way air valve to prevent backflow of the electronic atomizer 10, air enters from the air inlet 121 and reaches the end, facing the electronic cavity 120, of the air flow channel 510 accurately through the air inlet 130, then the rotating piece 520 in the air flow channel 510 is flushed open, enters the atomization cavity 110 through the air flow channel 510, reaches the atomization core 300 from the air inlet 310, and drives the aerosol in the atomization core 300 until the aerosol is sent to the aerosol outlet 111 for the user to use. When the airflow direction is the first direction, the microphone 600 located in the electronic cavity 120 can sense the airflow flowing in the air inlet 121, so as to open the atomizing core 300; when the airflow direction is the second direction, the airflow is blocked by the rotating piece 520 and cannot enter the air inlet 130, and the microphone 600 cannot feel the airflow from the air inlet 130, so that the operation of the atomizing core 300 is stopped. By providing the air inlet 130, the air flow is guided more accurately, and even if the reversed aerosol substrate seeps out from the gap between the rotating plate 520 and the air flow channel 510, the reversed aerosol substrate can preferentially flow down along the air inlet 130, and cannot immediately enter the area where other components are located, so that damage caused by reversed flow is further prevented.

In an embodiment, referring to fig. 2 and 3, an air inlet chamber 140 is further disposed in the housing 100; the air inlet 121 communicates with one end of the air intake duct 130 facing the air inlet 121 through the air intake chamber 140; the microphone 600 is disposed at a side of the intake chamber 140 connected to the intake duct 130.

In this embodiment, the microphone 600 is disposed in the air inlet chamber 140, so as to sense the change of the air flow. Meanwhile, the microphone 600 is disposed at a side of the air inlet chamber 140 connected to the air inlet 130, and thus, even if aerosol substrate finally flows back into the air inlet chamber 140 through the air inlet 130, it directly enters the air inlet chamber 140 by gravity, and does not directly contact the microphone 600. This becomes the last structural arrangement to prevent reflux damage.

Therefore, the electronic atomizer provided by the embodiment of the utility model can be used for blocking or absorbing the condensed aerosol matrix in three layers by arranging the transfer groove, the liquid absorbing piece in the transfer groove, the one-way air valve and the liquid storage groove, so that the damage to internal components after the aerosol is condensed is prevented; meanwhile, by arranging the unidirectional air valve which can be opened only in one direction, the microphone can not sense the change of air flow when a user blows and operates in error, and then the automatic starting can not be realized, so that the aerosol is prevented from being continuously generated and blown into the electronic cavity of the electronic atomizer, and other elements are damaged.

While the utility model has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
