Description

Atomizer and electronic atomizing 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 nebulizers generally include a nebulizer, which generally includes an air inlet channel, an air outlet channel, a liquid storage chamber for storing a nebulized liquid, and a nebulizing core in communication with the liquid storage chamber, and the nebulizing core generally includes a liquid guide and a heating element that are connected to each other. When the electronic atomization device works, atomized liquid in the liquid storage cavity is guided to the position of the heating body by the liquid guide body, aerosol is generated after the heating body heats the atomized liquid, and the aerosol flows out through the air outlet channel to be sucked by a user. The heating element can be in the form of metal heating wire, metal heating sheet, conductive ceramic heating element, and the liquid-guiding material can be cotton, porous ceramic, etc.

In the related art, after the atomized liquid in the liquid storage cavity is reduced due to guiding liquid, the internal pressure of the liquid storage cavity is reduced to form a certain negative pressure relative to the space in the air outlet channel communicated with the outside, and the negative pressure can increase the resistance of the atomized liquid in the subsequent guiding liquid guiding process, so that the user can smoothly guide the liquid guiding process for the subsequent atomized liquid, ensure that the user can suck the atomized liquid normally, and return air to the liquid storage cavity, namely, the outside air enters the liquid storage cavity through the micro-pores of the liquid guiding process, so that the air pressure in the liquid storage cavity is improved, and the negative pressure relative to the outside environment in the liquid storage cavity is reduced. The external environment herein refers to the space in the gas channel and the outside communicating with the gas channel.

However, in the air return process of the atomizer, air guided to the liquid storage cavity needs to permeate into the liquid storage cavity through liquid guiding, namely, a liquid guiding path of atomized liquid in the liquid storage cavity for guiding the liquid guiding and an air return path of external air in the liquid storage cavity through the liquid guiding are identical, and the flowing directions of the liquid guiding path and the air return path are opposite, so that the atomized liquid in the liquid storage cavity is prevented from guiding the liquid guiding by pressure generated by air to be fed into the liquid storage cavity to a liquid inlet of the liquid storage cavity wall, gravity of the atomized liquid in the liquid guiding and the pressure generated by the atomized liquid in the liquid guiding to the liquid inlet also prevent the air from entering the liquid storage cavity, the air cannot smoothly enter the liquid storage cavity, the atomized liquid at the liquid guiding position is difficult to be timely supplemented after being consumed, and a dry burning phenomenon is generated, the sucking taste of a user is reduced, and a heating element burns out the liquid guiding body when the dry burning phenomenon is serious. In addition, when the user sucks the atomizer, the atomized liquid heats the atomization core surface and atomizes, so that a layer of black carbon deposit can be deposited on the atomization core surface, and along with the extension of the service time of the atomizer, the carbon deposit deposited on the surface of the atomization core can be thicker and thicker, thereby influencing the taste of aerosol and the health of the user.

To achieve the above object, the present utility model provides an electronic atomizing device including the atomizer described in the above embodiment.

The atomizer and the electronic atomization device provided by the utility model have the beneficial effects that:

In the atomizer provided by the embodiment of the utility model, the air return hole is closer to the air outlet channel than the liquid inlet hole, namely, the air return hole is closer to the position above the atomizer than the liquid inlet hole in the axial direction of the atomizing core shell, so that the pressure of liquid in the liquid storage cavity received by the air return hole is smaller than the hydraulic pressure in the liquid storage cavity received by the liquid inlet hole, namely, the liquid pressure difference exists between the air return hole and the liquid inlet hole. Therefore, compared with the liquid inlet hole, the outside air is easier to enter the air guide channel formed between the inner peripheral wall of the sleeve and the inner pipe part and between the outer peripheral wall of the atomization core shell from the air return hole, then enters the liquid-free space and the capillary channel, and finally enters the liquid storage cavity. And at the liquid inlet hole, because the liquid pressure received by the liquid inlet hole is larger than the liquid pressure received by the air return hole, atomized liquid in the liquid storage cavity can be more easily led into the liquid guide through the liquid inlet hole. Because the connecting portion is arranged on the peripheral wall of the atomizing core shell between the air return hole and the liquid inlet, and one end of the sleeve, which is far away from the air outlet, is in sealing connection with the connecting portion, atomized liquid in the liquid storage cavity cannot enter the air guide channel from one end of the sleeve, which is far away from the air outlet, so that when external gas enters the air guide channel from the air return hole, the external gas cannot be blocked by the atomized liquid, and therefore, the atomized liquid can enter a liquid-free space which is communicated with the air guide channel in an unobstructed manner. Moreover, since the partition is provided with at least one capillary channel, when the atomized liquid in the liquid storage cavity flows into the liquid guide from the liquid inlet, the atomized liquid can flow into the liquid-free space and the air guide channel through the at least one capillary channel on the partition, but the atomized liquid flowing into the capillary channel is subjected to the air resistance of the capillary channel, so that the atomized liquid cannot completely fill the whole capillary channel. In this way, the atomized liquid cannot reach the liquid-free space and the air guide channel due to the air resistance of the capillary channel. In addition, because the air return hole is located closer to the air outlet channel than the liquid inlet hole, that is, the air return hole is located at a higher position than the liquid inlet hole in the axial direction of the atomization core shell, the pressure of the liquid in the liquid storage cavity received at the air return hole is smaller than the liquid pressure in the liquid storage cavity received at the liquid inlet hole, and therefore the external air can smoothly enter the liquid storage cavity through the air return hole, the air guide channel, the liquid-free space and at least one capillary channel on the partition piece; in contrast, since the pressure of the liquid received at the liquid inlet is greater than the hydraulic pressure received at the air return hole, only a small portion of the gas or even no gas enters the liquid storage cavity through the liquid inlet, and when the atomized liquid in the liquid storage cavity is introduced into the liquid guide body through the liquid inlet, the gas resistance of the atomized liquid is small or even no gas resistance is received, so that the atomized liquid can more smoothly flow into the liquid guide body through the liquid inlet. From the above, the atomized liquid in the liquid storage cavity is guided into the liquid guide through the liquid inlet, the liquid guide path and the external air are respectively two different paths which are mutually independent from each other through the air return hole, the air guide channel, the liquid-free space and at least one capillary channel on the partition piece, and the liquid pressure difference exists between the air return hole and the liquid inlet, so that the liquid pressure received by the liquid inlet is larger than the liquid pressure received by the air return hole, the atomized liquid can more easily break through the resistance of the gas to enter the liquid storage cavity and be guided into the liquid guide, and the external air can more smoothly enter into the liquid guide cavity continuously through the air return hole, the air guide channel, the liquid-free space and at least one capillary channel on the partition piece, thereby ensuring that the air pressure in the liquid storage cavity can be kept in an air pressure balance state with the external air pressure in the air guide channel continuously, further ensuring that the atomized liquid in the liquid storage cavity can be guided into the liquid guide through the liquid inlet continuously, avoiding the problem that the atomized liquid in the liquid guide is difficult to be obtained after the consumption of the atomized liquid in the liquid guide, the atomized liquid can be easily broken through the air inlet, the problem that the atomized liquid in time is difficult to obtain is solved, and the whole liquid can be prolonged, the service life of the liquid guide can be prolonged, and the life of the atomizer can be prolonged, and the life can be used, and the life the can be prolonged.

In addition, the accumulated suction parameter set is compared with a preset suction parameter set preset in a memory through the controller, and then the brake switch is controlled to be continuously connected with the electric connection of the atomizing core according to the comparison result, or the brake switch is controlled to be forcibly disconnected with the electric connection of the atomizing core. When the brake switch forcibly disconnects the electric connection of the atomizing core, the service life of the atomizing core reaches the limit, and the deposited carbon deposition is too much and is not suitable for continuous use, so that the user can know the prompt after the atomizer is automatically powered off, and the atomizing core deposited with the carbon deposition is replaced by a new atomizing core, thus the burnt smell problem of burning caused by the excessive carbon deposition on the surface of the atomizing core can be prevented, and the taste of aerosol and the health of the user are further influenced.

The inside of the shell 100 is provided with an inner pipe 110, a liquid storage cavity 120 for storing atomized liquid is formed between the outer wall of the inner pipe 110 and the inner wall of the shell 100, an air outlet channel 130 is formed in the inner periphery of the inner pipe 110, and an air outlet 140 communicated with the air outlet channel 130 is arranged on the shell 100.

The atomizing core 200 is provided in the housing 100, and the atomizing core 200 is connected to an end of the inner pipe 110 remote from the air outlet 140. The atomizing core 200 comprises a liquid guiding body 210 and a hollow atomizing core shell 220, at least one air return hole 221 and at least one liquid inlet hole 222 are formed in the atomizing core shell 220 in a penetrating mode, the air return hole 221 is closer to the air outlet channel 130 than the liquid inlet hole 222, the liquid guiding body 210 is arranged in a hollow space of the atomizing core shell 220, the liquid guiding body 210 is in contact connection with the air return hole 221 and the inner side wall of the atomizing core shell 220 at the liquid inlet hole 222, the air return hole 221 and the liquid inlet hole 222 are respectively communicated with the liquid guiding body 210 and the liquid storage cavity 120, and a connecting portion 223 is arranged on the peripheral wall of the atomizing core shell 220 between the air return hole 221 and the liquid inlet hole 222.

The sleeve 300 is sleeved on the outer circumference of the inner tube 110 and the atomizing core 220, one end of the sleeve 300, which is far away from the air outlet 140, is in sealing connection with the connecting portion 223, and the inner circumferential wall of the sleeve 300 is respectively arranged with the outer circumferential wall of the inner tube 110 and the outer circumferential wall of the atomizing core 220 at opposite intervals to form an air guide channel 310.

The partition 400 is disposed at one end of the liquid storage cavity 120 near the air outlet 140, and the partition 400 is connected to the sleeve 300, and a liquid-free space 410 is formed between the partition 400 and an inner wall of one end of the liquid storage cavity 120 near the air outlet 140, where the liquid-free space 410 is communicated with the air guide channel 310. And, at least one capillary channel 420 is perforated on the partition 400, and the capillary channel 420 communicates the liquid-free space 410 with the liquid storage cavity 120.

The controller 703 is used to compare with a preset set of suction parameters preset in the memory 701 according to the accumulated set of suction parameters, thereby controlling the brake switch 702 to switch on or off the electrical connection of the atomizing core 200. The accumulated suction parameter set is an accumulated value of at least one suction parameter monitored by the atomizer when suction action is sensed, and the preset suction parameter set is a value of at least one preset suction parameter.

In the embodiment of the present application, the inner tube 110 is disposed in the outer shell 100, and when the embodiment is implemented, the outer shell 100 and the inner tube 110 may be in an integrally formed structure or a split structure. The air outlet 140 is formed on the housing 100, the air outlet 140 is communicated with the air outlet channel 130 formed by the inner periphery of the inner tube 110, and the aerosol generated after the atomized liquid is heated and atomized sequentially passes through the air outlet channel 130 and the air outlet 140 to be led out to the outside for the user to inhale.

The fact that the air return hole 221 is closer to the air outlet channel 130 than the liquid inlet hole 222 means that the air return hole 221 and the liquid inlet hole 222 are arranged at intervals along the axial direction of the atomization core shell 220, the air return hole 221 is arranged above the liquid inlet hole 222, one end of the liquid inlet hole 222 close to the air outlet 140 is arranged above the liquid inlet hole 222, namely, the position of the air return hole 221 and the position of the liquid inlet hole 222 have a height difference in the liquid storage cavity 120, and therefore the pressure of liquid in the liquid storage cavity 120 received by the air return hole 221 is smaller than the pressure in the liquid storage cavity 120 received by the liquid inlet hole 222, namely, a liquid pressure difference exists between the air return hole 221 and the liquid inlet hole 222. Therefore, compared to the liquid inlet 222, the external air more easily enters the air guide channel 310 formed between the inner peripheral wall of the sleeve 300 and the inner tube 110 and the outer peripheral wall of the atomizing core 220 from the air return hole 221, then enters the liquid-free space 410 and the capillary channel 420, and finally enters the liquid storage chamber 120. In the liquid inlet 222, the pressure of the liquid in the liquid storage chamber 120 received in the liquid inlet 222 is larger than the hydraulic pressure received in the air return hole 221, so that the atomized liquid in the liquid storage chamber 120 can be more easily introduced into the liquid guide 210 through the liquid inlet 222. In the embodiment of the present application, the number of the air return holes 221 may be one or more, the number of the liquid inlet holes 222 may be one, and the number of the air return holes 221 and the number of the liquid inlet holes 222 may be equal or unequal, which is not limited herein.

The liquid guide 210 arranged in the hollow space of the atomization core shell 220 is in contact connection with the inner side wall of the atomization core shell 220 at and around the air return hole 221 on the atomization core shell 220 and the inner side wall of the atomization core shell 220 at and around the liquid inlet 222 on the atomization core shell 220, so that the liquid guide 210 can completely shield the air return hole 221 and the liquid inlet 222, and the air return hole 221 can be communicated with the liquid guide 210 and the liquid storage cavity 120, and the liquid inlet 222 can also be communicated with the liquid guide 210 and the liquid storage cavity 120.

Preferably, in the embodiment of the present application, the liquid guide 210 is closely contacted with the inner sidewall of the atomizing core shell 220 at the air return hole 221 and the liquid inlet hole 222, so that leakage of the atomized liquid can be prevented. More preferably, in the embodiment of the present application, the outer periphery of the liquid guide 210 may be in contact with the inner side wall of the atomizing core shell 220, and since the liquid guide 210 has a certain liquid storage function, when the outer periphery of the liquid guide 210 and the inner side wall of the atomizing core shell 220 are in contact with each other, the effect of preventing the dry combustion of the atomizing core 200 in the state of no or little liquid in the liquid storage cavity 120 can be achieved. Further, when the outer circumference of the entire liquid guide 210 is in close contact with the inner sidewall of the atomizing core housing 220, the leakage of the atomizing core 200 can be prevented.

In the embodiment of the present application, an end of the sleeve 300 near the air outlet 140 will be referred to as an upper end of the sleeve 300, and an end of the sleeve 300 remote from the air outlet 140 will be referred to as a lower end of the sleeve 300. The lower end portion of the sleeve 300 extends toward a direction away from the air outlet 140 and is hermetically connected to the connection portion 223, and the inner circumferential wall of the sleeve 300 is disposed at opposite intervals with respect to the outer circumferential wall of the inner tube portion 110 and the outer circumferential wall of the atomizing core housing 220, respectively, to form the air guide passage 310, so that the external air can directly enter the air guide passage 310 from the air return hole 221. Further, the sealing connection of the lower end portion of the sleeve 300 to the connection portion 223 can prevent the atomized liquid in the liquid storage chamber 120 from entering the air guide passage 310 from the lower end portion of the sleeve 300.

In the embodiment of the present application, referring to fig. 3 and 5, the connection portion 223 may be an annular structure protruding on the atomizing core shell 220 at the peripheral wall between the air return hole 221 and the liquid inlet hole 222, and the lower end portion of the sleeve 300 is connected with the connection portion 223 of the annular structure in a sealing manner; alternatively, the connection portion 223 may be a connection groove (not shown) concavely formed on the outer peripheral wall of the atomizing core 220, the inner cylinder wall of the lower end portion of the sleeve 300 is provided with a protrusion corresponding to the connection groove of the atomizing core 220, and the protrusion may be inserted into the connection groove of the atomizing core 220, so as to realize the sealing connection between the sleeve 300 and the connection groove of the atomizing core 220. The advantage of providing the connection portion 223 is that when the lower end portion of the sleeve 300 is in sealing connection with the connection portion 223 at the outer circumferential wall of the atomizing core housing 220, the atomized liquid in the liquid storage chamber 120 does not enter the air guide channel 310 from the lower end portion of the sleeve 300, so that when the external air enters the air guide channel 310 from the air return hole 221, the external air is not blocked by the atomized liquid, and thus can enter the liquid-free space 410 which is communicated with the air guide channel 310. Of course, in other embodiments of the present application, the present application is not limited as long as the sealing connection between the lower end portion of the sleeve 300 and the connection portion 223 can be achieved, so that the atomized liquid cannot enter into the air guide 310 from below the sleeve 300.

In the embodiment of the present application, the end of the liquid storage cavity 120 near the air outlet 140 is the top of the liquid storage cavity 120. The partition 400 is disposed at the top of the liquid storage chamber 120, and the partition 400 is connected to the upper end of the sleeve 300, a liquid-free space 410 without atomized liquid is formed between the partition 400 and the inner wall of the top of the liquid storage chamber 120, and the liquid-free space 410 can be communicated with the air guide channel 310, i.e., the external air conducted from the air return hole 221 can enter the liquid-free space 410 through the air guide channel 310. Moreover, since the partition 400 is further provided with at least one capillary channel 420, the capillary channel 420 is used for communicating the liquid-free space 410 with the liquid storage cavity 120, and thus, the external air entering the liquid-free space 410 can also enter the liquid storage cavity 120 through the at least one capillary channel 420. It should be noted that, when the number of the capillary channels 420 is one or more, the plurality of capillary channels 420 may be distributed on the separator 400 along the circumferential direction of the separator 400, which is not limited herein.

The capillary passage 420 may be penetrated into the separator 400 in the axial direction of the separator 400, or the capillary passage 420 may be penetrated into the separator 400 at an inclination with respect to the axial direction of the separator 400. The capillary passage 420 has the function that after the external air enters the capillary passage 420, capillary air resistance can be formed in the capillary passage 420, at this time, the atomized liquid in the liquid storage cavity 120 cannot flow in the capillary passage 420 due to the blocking of the capillary air resistance, and the capillary air resistance formed in the capillary passage 420 cannot influence the flow of the gas, i.e., the external air can still flow in the capillary passage 420. In other words, the capillary passage 420 has a "liquid-tight ventilation" structure, so that the external air can enter the liquid storage chamber 120 through the air return hole 221, the air guide passage 310, the liquid-free space 410, and at least one capillary passage 420 on the partition 400, thereby returning air into the liquid storage chamber 120.

It should be noted that, in the technical field of electronic atomization, the term "back air" refers to that when the total pressure of the gas and the liquid in the liquid storage cavity 120 is smaller than the external gas pressure in the air outlet channel 130 connected to the outside, the air in the liquid storage cavity 120 generates a negative pressure with respect to the air outlet channel 130, and as the pressure in the liquid storage cavity 120 is continuously reduced, the negative pressure is continuously increased, and when the negative pressure reaches a certain threshold value, the pressure of the external gas breaks through the pressure in the liquid storage cavity 120 and enters into the liquid storage cavity 120 through the opening on the side wall of the atomization core shell 220, that is, the external gas enters into the liquid storage cavity 120. The pressure in the reservoir 120 includes the pressure of the gas against the atomized liquid, the pressure of the atomized liquid against the sidewall of the atomizing core 220, and the gravity of the atomized liquid itself. After the external air returns to the liquid storage cavity 120, the pressure in the liquid storage cavity 120 is increased again, so that the air pressure outside the liquid storage cavity 120 and the pressure in the liquid storage cavity 120 are restored to the balance state again, and the atomized liquid in the liquid storage cavity 120 can flow out again.

In the embodiment of the present application, referring to fig. 8, the controller 703, the memory 701 and the brake switch 702 are all mounted on the control circuit board 705, and the control circuit board 705 is disposed in the housing 100 (as shown in fig. 3 and 6). The controller 703 is electrically connected to the atomizing core 200, the memory 701, and the brake switch 702 via the bus a, that is, the controller 703 is communicatively connected to the atomizing core 200, the memory 701, and the brake switch 702 via the bus a. Further, a brake switch 702 is electrically connected to the atomizing core 200, and the brake switch 702 is used to turn on or off the electrical connection of the atomizing core 200. For example, when the brake switch 702 receives the off signal transmitted from the controller 703, the brake switch 702 performs an operation of opening the electrical connection of the atomizing core 200 according to the received off signal; when the brake switch 702 receives the on signal transmitted from the controller 703, the brake switch 702 performs an operation of turning on the electrical connection of the atomizing core 200 according to the received on signal.

In a specific implementation, the controller 703 may obtain the values of the respective parameters in the cumulative pumping parameter set, compare the obtained values with the corresponding values of the respective parameters of the preset pumping parameter set in the memory 701, and then the controller 703 determines whether to send a power-off instruction for disconnecting the electrical connection of the atomizing core 200 to the brake switch 702 according to the result obtained after the comparison, and if the brake switch 702 receives the power-off instruction of the controller 703, the brake switch 702 immediately performs a power-off operation on the atomizing core 200. If the brake switch 702 does not receive the power-off instruction of the controller 703, the brake switch 702 continues the operation of keeping the electrical connection of the atomizing core 200 on.

The brake switch 702 being electrically connected to the atomizing core 200 means that the controller 703 is electrically connected to the atomizing core 200, and at this time, the controller 703 may set parameters such as output power, output current, and operating time of the atomizing core 200. The breaking of the electrical connection of the atomizing core 200 by the brake switch 702 means that the controller 703 is not electrically connected to the atomizing core 200, and the atomizing core 200 is in the off state.

Further, the brake switch 702 may be an actual physical switch, a switching element, or a virtual switching unit. The specific structure of the brake switch 702 belongs to the existing technical scheme, for example, the functions of power-off and electrical connection maintaining of the virtual switch unit can be realized through high and low levels in a circuit, and the brake switch can also be a triode or a transistor, and the switching-on and the switching-off of the triode or the transistor can be controlled through the high or low voltage transmitted by the controller 703.

The cumulative aspiration parameter set is a cumulative value of at least one aspiration parameter that the nebulizer monitors when sensing an aspiration action. In the embodiment of the present application, it is preferable that the air flow sensor or the air pressure sensor is disposed in the atomizer, for example, the air flow sensor or the air pressure sensor is disposed at the air inlet 180 (the specific structure of the air inlet 180 will be described later), so that the air flow sensor or the air pressure sensor can sense that the air flow at the air inlet 180 changes or the air pressure changes when the user sucks the atomizer. The controller 703 is capable of obtaining a cumulative value of the at least one monitored pumping parameter when the airflow sensor or the air pressure sensor senses a change in airflow or a change in air pressure at the air inlet 180. And the set of predetermined pumping parameters is a value of at least one of the predetermined pumping parameters. When the controller 703 in the atomizer senses the user to suck through the air flow sensor, the value of the monitored actual sucking parameter is accumulated through the counter or the monitor, the accumulated value of the actual sucking parameter is compared with the corresponding value of the preset sucking parameter, and then whether to send a power-off instruction to the controller 703 is judged according to the comparison result.

Because the partition 400 is provided with at least one capillary channel 420, when the atomized liquid in the liquid storage cavity 120 flows into the liquid guide 210 from the liquid inlet 222, the atomized liquid may want to flow into the liquid-free space 410 and the air guide channel 310 through the at least one capillary channel 420 on the partition 400, but the atomized liquid flowing into the capillary channel 420 is not completely filled in the whole capillary channel 420 due to the air resistance of the capillary channel 420. In this way, the atomized liquid cannot reach the liquid-free space 410 and the air guide channel 310 due to the air resistance of the capillary channel 420. In addition, since the air return hole 221 is located closer to the air outlet channel 130 than the liquid inlet hole 222, that is, the air return hole 221 is located higher than the liquid inlet hole 222 in the axial direction of the atomizing core 220, so that the pressure of the liquid in the liquid storage chamber 120 received at the air return hole 221 is smaller than the hydraulic pressure in the liquid storage chamber 120 received at the liquid inlet hole 222, the external air can smoothly pass through the air return hole 221, the air guide channel 310, the liquid-free space 410, and at least one capillary channel 420 on the partition 400 to enter the liquid storage chamber 120; in contrast, since the pressure of the liquid received at the liquid inlet 222 is greater than the hydraulic pressure received at the return air hole 221, only a small portion of the gas or even no gas enters the liquid storage chamber 120 through the liquid inlet 222, and when the atomized liquid in the liquid storage chamber 120 is introduced into the liquid guide 210 through the liquid inlet 222, the atomized liquid receives little or no gas resistance, and thus can flow into the liquid guide 210 through the liquid inlet 222 more smoothly. As can be seen from the above, the liquid guiding path of the atomized liquid in the liquid storage cavity 120 and the external air are led into the liquid guiding cavity 210 through the liquid inlet 222, and the air returning path of the air returning to the liquid storage cavity 120 through the air returning hole 221, the air guiding channel 310, the liquid free space 410 and the at least one capillary channel 420 on the partition 400 are two different paths independent of each other, and a liquid pressure difference exists between the air returning hole 221 and the liquid inlet 222, the liquid pressure received at the liquid inlet 222 is greater than the liquid pressure received at the air returning hole 221, so that the atomized liquid can more easily break through the resistance of the air to be led into the liquid guiding cavity 120, and the external air can more smoothly enter into the liquid storage cavity 120 through the air returning hole 221, the air guiding channel 310, the liquid free space 410 and the at least one capillary channel 420 on the partition 400, so that the air pressure in the liquid storage cavity 120 can be kept in a state of being balanced with the external air pressure in the air outlet channel 130, and further ensuring that the atomized liquid in the liquid storage cavity 120 can continuously pass through the liquid inlet 221, the liquid guiding hole 221 and the atomized liquid in the liquid storage cavity 210 can be prevented from being damaged, and the whole life of the liquid guiding cavity 210 can be prolonged, and the life of the atomized liquid can be prolonged, and the liquid guiding device can be prevented from being damaged.

In addition, in the present utility model, the controller 703 may compare the accumulated pumping parameter set with a preset pumping parameter set preset in the memory 701, and then control the brake switch 702 to continuously connect the atomizing core 200 or control the brake switch 702 to forcibly disconnect the atomizing core 200 according to the comparison result. When the brake switch 702 forcibly disconnects the electrical connection of the atomizing core 200, the user is prompted that the service life of the atomizing core 200 has reached the limit, and the deposited carbon deposition is too much and is not suitable for continuous use, so that the user can know the prompt after the atomizer is automatically powered off, and replace the atomizing core 200 deposited with carbon deposition with a new one, thus the burnt smell problem of burning caused by too much carbon deposition on the surface of the atomizing core 200 can be prevented, and the taste of aerosol and the health of the user are further influenced.

Further, the cumulative suction parameter set includes at least one of a cumulative suction time period and a cumulative suction number, that is, the cumulative suction parameter set may include a cumulative suction time period; alternatively, the cumulative aspiration parameter set may also include a cumulative aspiration number; still alternatively, the cumulative suction parameter set may further include a cumulative suction duration and a cumulative suction number, which is not limited herein. The preset suction parameter set comprises at least one parameter of preset suction duration and preset suction times, and the preset suction parameter set can comprise preset suction duration; alternatively, the set of preset suction parameters may also include a preset number of suction times; still alternatively, the set of preset suction parameters may further include a preset suction duration and a preset number of suction times. For example, the preset suction period may be set to 3000s, and the preset number of suction times may be set to 3000. Of course, in other embodiments, the preset pumping duration and the preset pumping frequency may be set according to the volume of the atomized liquid in the liquid storage cavity 120, and when the atomized liquid in the liquid storage cavity 120 is less, the preset pumping duration and the preset pumping frequency may be set to be smaller; when there is more atomized liquid in the liquid storage chamber 120, the preset pumping time period and the preset pumping times may be set to be larger, which is not limited herein.

Further, the controller 703 is specifically configured to send the value of the accumulated pumping parameter sensed each time to the memory 701, compare whether the accumulated pumping parameter reaches a corresponding preset pumping parameter, and when the accumulated pumping parameter is greater than or equal to the preset pumping parameter, control the brake switch 702 to forcibly disconnect the electrical connection of the atomizing core 200. The accumulated pumping parameter may be accumulated pumping time, accumulated pumping times, accumulated pumping time and accumulated pumping times. Correspondingly, the preset suction parameter may be a preset suction duration, a preset suction frequency, or a preset suction duration and a preset suction frequency. Describing the cumulative pumping parameter as the cumulative pumping duration and the preset pumping parameter as the preset pumping duration, specifically, the controller 703 sends the cumulative pumping duration monitored each time to the memory 701, and after acquiring the preset pumping duration in the memory 701, the controller 703 compares whether the cumulative pumping duration reaches the corresponding preset pumping duration. That is, the controller 703 compares the accumulated pumping time period with the value of the preset pumping time period, and when the accumulated pumping time period is greater than or equal to the preset pumping time period, prompts the user that the service life of the atomizing core 200 has reached the limit, and the deposited carbon deposit is too much to be suitable for continuous use, so that the user can know the prompt after finding that the atomizer is automatically powered off, and replace the atomizing core 200 deposited with carbon deposit with a new one, thus preventing the burnt smell problem caused by too much carbon deposit on the surface of the atomizing core 200, and further affecting the taste of the aerosol and the health of the user. It should be noted that, when the accumulated pumping time period is less than the preset pumping time period, the working time of the atomizer is shorter, and less or even no carbon deposit is generated on the surface of the atomizing core 200, and the continuous use of the atomizing core 200 will not affect the taste of the aerosol and the health of the user, so the controller 703 controls the brake switch 702 to keep on the electrical connection of the atomizing core 200.

The above description is applicable to a reusable atomizer, i.e., when there is more carbon deposition on the surface of the atomizing core 200, the influence of carbon deposition on the taste and health of the suction can be eliminated by replacing the atomizing core with a new one. However, if the atomizer is a disposable atomizer, the controller 703 may also compare the accumulated pumping time period with a value of a preset pumping time period to determine whether carbon deposits are deposited on the surface of the atomizing core 200 in the atomizer. For example, when the accumulated pumping time period is greater than or equal to the preset pumping time period, the working time of the atomizer is prompted to reach the limit, so that the carbon deposition on the surface of the atomizing core 200 is more, and the atomizing core 200 is not suitable for continuous use, if the atomizing core 200 is continuously used, the taste of aerosol and the health of a user can be affected, so that the user can know the prompt after finding that the atomizer is automatically powered off, and the whole atomizer can be recovered.

Further, referring to fig. 4 and 7, the capillary passage 420 has a first pitch L1 along the radial direction of the separator 400, and the air guide passage 310 has a second pitch L2 along the radial direction of the atomizing core housing 220, and the first pitch L1 of the capillary passage 420 is smaller than the second pitch L2 of the air guide passage 310.

The first spacing L1 of the capillary channels 420 is 0.2mm-2mm. In the embodiment of the application, by reasonably designing the first spacing L1 of the capillary channel 420 to be 0.2mm-2mm, atomized liquid in the liquid storage cavity 120 can not enter the liquid-free space 410 communicated with the capillary channel 420 under the air resistance action of the capillary channel 420, and meanwhile, external air can enter the liquid storage cavity 120 through the air return hole 221, the air guide channel 310, the liquid-free space 410 and the capillary channel 420, so that the arrangement of the capillary channel 420 can prevent the atomized liquid from entering the air guide channel 310 through the capillary channel 420 and the liquid-free space 410, and the external air can return air to the liquid storage cavity 120 through the capillary channel 420.

As for the specific value of the first interval L1 of the capillary passage 420, it may be set according to the concentration degree of the atomized liquid, for example, when the concentration degree of the atomized liquid is relatively large, the first interval L1 of the capillary passage 420 may be set to be slightly larger; when the concentration of the atomized liquid is smaller, the first interval L1 of the capillary channel 420 may be set to be smaller, so long as capillary air resistance can be formed in the capillary channel 420, so as to satisfy the effect that the outside air passes through and the atomized liquid cannot pass through, and the first interval L1 of the capillary channel 420 is not limited in the present application.

Further, in order to block the atomized liquid by the capillary air lock formed by the capillary channel 420, in this embodiment, the length of the capillary channel 420 along the axial direction of the separator 400 is 3mm or more, and if the length of the capillary channel 420 is less than 3mm, the atomized liquid may break through the capillary air lock of the capillary channel 420 and be introduced into the liquid-free space 410 and the air guide channel 310.

In the embodiment of the present application, the partition 400 has an annular structure, and the partition 400 having an annular structure is sleeved on the outer periphery of the inner tube 110. As shown in fig. 3, 4, 6 and 7, the end of the partition 400 facing away from the air outlet 140 is provided with a mounting groove 460 in the axial direction of the partition 400, and the end of the sleeve 300 adjacent to the air outlet 140 is sealingly inserted into the mounting groove 460. At this time, the outer peripheral wall of the separator 400 is in sealing contact with the inner wall of the housing 100, and the inner peripheral wall of the separator 400 is spaced apart from the outer peripheral wall of the inner tube 110.

Specifically, the mounting groove 460 may be provided on the separator 400 in several ways, one in which the mounting groove 460 is provided near the center of the separator 400 and on the inner peripheral wall of the separator 400 (fig. 3 and 4), and one in which the mounting groove 460 is provided on the separator 400 at a position between the capillary passage 420 and the inner peripheral wall of the separator 400 (fig. 6 and 7).

As shown in fig. 3 and 4, when the mounting groove 460 is provided on the inner circumferential wall of the partition 400 in the axial direction of the partition 400, the mounting groove 460 is closest to the center position of the partition 400, and at this time, the end portion of the sleeve 300 near the air outlet 140 is sealingly inserted into the mounting groove 460, so that the sleeve 300 is connected to the partition 400, and thus the inner wall of the end of the sleeve 300 near the air outlet 140 and the inner circumferential wall of the partition 400 can be smoothly connected in transition. In this case, the inner peripheral wall of the partition 400 and the inner side wall of the end portion of the sleeve 300 near the air outlet 140 are disposed at a relative interval from the outer peripheral wall of the inner tube portion 110. That is, the space 41 formed between the inner peripheral wall of the partition 400 and the outer peripheral wall of the inner tube 110 is provided at a relatively spaced apart position, and the space 41 can directly communicate the gas guide passage 310 formed between the inner peripheral wall of the sleeve 300 and the outer peripheral walls of the inner tube 110 and the atomizing core 220 and the liquid-free space 410.

As shown in fig. 6 and 7, when the mounting groove 460 is provided at a position between the capillary passage 420 on the separator 400 and the inner peripheral wall of the separator 400 in the axial direction of the separator 400, i.e., at a position farther from the outer peripheral wall of the inner tube portion 110, in this case, a space 42 is formed between the inner peripheral wall of the separator 400 and the outer peripheral wall of the inner tube portion 110 at a relative interval, which space 42 communicates with the gas guide passage 310 and the liquid-free space 410. At this time, one end of the sleeve 300 near the air outlet 140 (i.e., the upper end of the sleeve 300) may be bent, so that the inner wall of the upper end of the sleeve 300 may be smoothly connected with the inner circumferential wall of the partition 400 after the upper end of the sleeve 300 is sealingly inserted into the mounting groove 460. Of course, the inner wall of the upper end portion of the sleeve 300 and the inner peripheral wall of the partition 400 may be transitionally connected by a cambered surface or other means, which is not limited thereto.

Further, as shown in fig. 3 and 6, the outer periphery of the end face of the partition 400 near the air outlet 140 is provided with a flange 470, and the end face of the flange 470 far from the partition 400 and near the air outlet 140 is in sealing abutment against the top inner wall of the housing 100, so that the above-mentioned liquid-free space 410 is formed between the end face of the partition 400 near the air outlet 140, the top inner wall of the housing 100 and the inner tube 110, and the liquid-free space 410 is communicated with the outside through the air guide channel 310, the air return hole 221 and the air outlet channel 130. The function of setting the liquid-free space 410 is that, because the liquid-free space 410 is communicated with the outside, that is, when the atomized liquid is injected into the liquid storage cavity 120, the relative balance between the air pressure in the liquid storage cavity 120 and the air pressure of the outside can be ensured, so that the situation that the air pressure is increased due to the gradual increase of the volume of the atomized liquid in the liquid storage cavity 120 can be avoided. If the liquid-free space 410 is not communicated with the outside, the air pressure in the liquid storage cavity 120 is greater than the air pressure of the outside, so that the atomized liquid can be injected into the liquid storage cavity 120 only by a larger external force, and even can not be injected into the liquid storage cavity 120. On the contrary, under the circumstance that the atomized liquid gradually decreases, the air pressure in the liquid storage cavity 120 also decreases, because the liquid-free space 410 is communicated with the outside, in order to keep the air pressure in the liquid storage cavity 120 balanced with the outside air pressure, the outside air enters the air guide channel 310 through the air return hole 221 and enters the liquid-free space 410, and then enters the capillary channel 420 and the liquid storage cavity 120, so that the purpose of returning air into the liquid storage cavity 120 is achieved, and the air pressure in the liquid storage cavity 120 can be basically equal to the outside air pressure after returning air.

Further, the partition 400 has a first surface 430 and a second surface 440 opposite to each other, the first surface 430 is disposed near the air outlet 140, the capillary channel 420 is disposed on the second surface 440 along the axial direction of the partition 400, the first surface 430 is disposed with a liquid storage channel 450 communicating with the capillary channel 420 along the axial direction of the partition 400, and the distance between the liquid storage channels 450 along the radial direction of the partition 400 is larger than the first distance L1 between the capillary channels 420.

Specifically, in the embodiment of the present application, the liquid storage channel 450 is disposed on the first surface 430 of the separator 400, and the capillary channel 420 is disposed on the second surface 440 of the separator 400 and penetrates into the liquid storage channel 450, i.e., the liquid storage channel 450 communicates with the capillary channel 420 and penetrates through the first surface 430 and the second surface 440 of the separator 400 in the axial direction of the separator 400. The liquid storage channel 450 in this embodiment is used to guide the external air guided from the air return hole 221, the air guide channel 310 and the liquid-free space 410 to the capillary channel 420, and then to the liquid storage cavity 120 through the capillary channel 420, so as to achieve the air return in the liquid storage cavity 120.

Because the partition 400 is located in the liquid storage cavity 120, and the capillary channel 420 communicates the liquid storage cavity 120 with the liquid-free space 410, a part of atomized liquid may enter the capillary channel 420 in the liquid storage cavity 120, and atomized liquid entering the capillary channel 420 may also enter the liquid-free space 410 communicated with the capillary channel 420, so that atomized liquid enters the air guide channel 310 communicated with the liquid-free space 410. Therefore, the liquid storage channel 450 may also be used to store a portion of the atomized liquid introduced from the capillary channel 420, prevent the atomized liquid introduced from the capillary channel 420 from flowing into the liquid-free space 410 or the air guide channel 310, and further reduce the resistance of the external air entering into the capillary channel 420 and the liquid storage chamber 120 through the air return hole 221, the air guide channel 310 and the liquid-free space 410, so that the air return is smoother. When the external air is introduced into the liquid storage channel 450 from the air return hole 221, the air guide channel 310 and the liquid-free space 410, a small amount of atomized liquid in the liquid storage channel 450 can be brought back into the liquid storage cavity 120.

In the present embodiment, the interval of the liquid storage channels 450 in the radial direction of the separator 400 is larger than the first interval L1 of the capillary channels 420, and the liquid storage channels 450 may be funnel-shaped in a cross section in the axial direction of the separator 400; alternatively, the liquid storage channel 450 is oval, circular, square, etc. in section along the radial direction of the partition 400; alternatively, the liquid storage channel 450 may have a funnel shape in a cross section along the axial direction of the separator 400, and the liquid storage channel 450 may have a specific shape such as an oval shape, a circular shape, or a square shape in a cross section along the radial direction of the separator 400, which is not limited herein.

Further, the capillary channels 420 are plural, and the plural capillary channels 420 are provided on the separator 400 at intervals along the circumferential direction of the atomizer. Thus, the external air can sequentially pass through the air return hole 211, the air guide channel 310, the liquid-free space 410 and the liquid storage channel 450 and then be led into the liquid storage cavity 120 from the plurality of capillary channels 420, so that the speed of the external air entering the liquid storage cavity 120 is improved, the air pressure in the liquid storage cavity 120 can be kept in a state of keeping air pressure balance with the air pressure in the air outlet channel 130, the atomized liquid in the liquid storage cavity 120 can be led into the liquid guide 210 continuously through the liquid inlet hole 222, and the risk of damage caused by dry burning of the liquid guide liquid is further reduced.

Based on all of the above embodiments, as shown in connection with fig. 3 and 6, the end of the housing 100 facing away from the air outlet 140 is provided with a mounting opening 170. The atomizer further comprises a first base 500 and a second base 600, wherein the first base 500 is arranged in the housing 100, the second base 600 is arranged at the mounting opening 170, one end of the atomizing core shell 220, which is away from the inner pipe 110, is connected with the first base 500, and the housing 100, the inner pipe 110 and the first base 500 are enclosed to form the liquid storage cavity 120. The first base 500 is provided with an air inlet 510 communicated with the air outlet channel 130, the side wall of the housing 100 between the first base 500 and the second base 600 is provided with an air inlet 180, and the air inlet 180 is communicated with the air inlet 510. That is, when the atomizer is in use and the air pressure in the liquid storage chamber 120 is reduced due to continuous consumption of the atomized liquid, the external air will enter the liquid storage chamber 120 through the air inlet 180, the air inlet 510, the air return hole 221, the air guide channel 310, the liquid-free space 410 and at least one capillary channel 420 on the partition 400 in sequence. When the atomizer is in an unused state and a negative pressure is formed between the air pressure in the liquid storage chamber 120 and the air pressure in the air outlet channel 130 or the external atmospheric pressure, the external air may enter the air return hole 221 from the air inlet 180 and the air inlet 510 to return air into the liquid storage chamber 120, and may enter the air return hole 221 from the air outlet 140 and the air outlet channel 130 to return air into the liquid storage chamber 120, so that no matter whether the external air enters from the air inlet 180 or the air outlet 140, the external air is returned to the liquid storage chamber 120 through the air return hole 221 with smaller hydraulic pressure. It should be noted that, since the end of the sleeve 300 away from the air outlet 140 is connected to the connecting portion 223 in a sealing manner, no atomized liquid enters the air guide channel 310 formed between the inner peripheral wall of the sleeve 300 and the outer peripheral wall of the inner tube 110 and the atomizing core shell 220, and therefore, the pressure of the atomized liquid in the liquid storage chamber 120 received by the air return hole 221 is zero.

Further, referring to fig. 3 and 6, the atomizer further includes a bracket 700, the bracket 700 being located between the first and second bases 500 and 600, and an outer circumferential wall of the bracket 700 being in sealing abutment with an inner circumferential wall of the housing 100. A receiving groove 710 is formed in one side of the bracket 700 facing the second base 600, a first opening 720 is formed in the groove wall of the receiving groove 710 corresponding to the air inlet 180 in a penetrating manner, and the first opening 720 is communicated with the air inlet 180; and, a second opening 730 is perforated on the bottom wall of the receiving groove 710, and the second opening 730 is communicated with the air inlet 510. Therefore, the air inlet 180, the first opening 720, the accommodating groove 710, the second opening 730 and the air inlet 510 are sequentially communicated to form an air inlet channel of the atomizer, and the external air can enter the hollow space of the atomizing core shell 220 through the air inlet channel and be led out from the air outlet channel 130 and the air outlet 140. The control circuit board 705 in the above embodiment is disposed in the accommodating groove 710, and the memory 701, the brake switch 702, and the air flow sensor or the air pressure sensor are all mounted on the control circuit board 705. Therefore, when the user sucks the atomizer, the external air flows into the accommodating groove 710 from the air inlet 180 and the first opening 720, and the air flow sensor or the air pressure sensor disposed in the accommodating groove 710 can sense the change of the air flow or the air pressure at the air inlet 180, and at this time, the control circuit board 705 controls the atomizing core 200 to perform the heating and atomizing operation.

Further, referring to fig. 3 and 6, one end of the first base 500 away from the air inlet 180 is convexly provided with a barb portion 520, the barb portion 520 is bent towards the inner wall of the liquid storage cavity 120, that is, the barb portion 520 is bent towards the axis of the atomizing core shell 220 along the radial direction of the atomizing core shell 220, the barb portion 520 and the side wall of the end of the sleeve 300 away from the air outlet 140 are spaced to form a liquid inlet 530, a liquid inlet space 540 is formed between the barb portion 520 and the first base 500, and the liquid inlet space 540 is communicated with the liquid inlet 530 and the liquid inlet hole 222. The atomized liquid in the liquid storage chamber 120 is then introduced into the liquid guide 210 through the liquid inlet 530, the liquid inlet space 540, and the liquid inlet 222 in this order.

Further, the barb portion 520 is disposed on the side of the first base 500 facing the liquid storage cavity 120, and in order to facilitate observation of the consumption of the atomized liquid in the liquid storage cavity 120, the portion of the housing 100 in the liquid storage cavity 120 is generally made of transparent or semitransparent material, at this time, when the liquid storage cavity 120 is observed from the outside of the atomizer, the bottom of the liquid storage cavity 120 is a bent portion of the barb portion 520, and a portion of the atomized liquid can be stored in the liquid inlet space 540 formed between the barb portion 520 and the first base 500. Thus, when the user observes that the bottom of the liquid storage cavity 120 is free of atomized liquid, as atomized liquid is stored in the liquid inlet space 540, the atomizer can actually suck for a period of time, and the user can be prompted that the atomizer is in a state of being free of atomized liquid, so that atomized liquid can be added into the liquid storage cavity 120 again.

The barb 520 also has a function of keeping the atomized liquid in the liquid inlet space 540 when the atomizer is in an inclined use state and the atomized liquid in the liquid storage cavity 120 is insufficient (for example, when the atomizer is vertically placed, the liquid level of the atomized liquid is located at a position opposite to the liquid inlet 222), so that the atomized liquid is prevented from flowing out of the liquid inlet 530 into the liquid storage cavity 120 along with the inclined angle to cause the atomized liquid to be unable to contact the position of the liquid inlet 222, and thus the atomized liquid is unable to be conducted to the liquid guide 210 through the liquid inlet 222, and the liquid guide 210 is free from dry burning.

Correspondingly, the embodiment of the application also provides an electronic atomization device, which comprises the atomizer in any embodiment. The electronic atomization device further comprises a battery assembly (not shown), wherein the battery assembly is electrically connected with the heating element in the atomizer and is used for providing current for the heating element so that the heating element can generate heat after being electrified and heat atomized liquid which is atomized and conducted to the heating element.

In some specific application scenarios, the battery assembly of the embodiment may be a power supply of a lithium battery or the like, and in addition, the electronic atomization device of the embodiment may further include a control circuit board, wherein the control circuit board is electrically connected with the battery assembly and the heating element respectively, and when in use, the control circuit board can control the battery assembly to supply power to the heating element, so that the heating element is electrified and heats to atomize the atomized liquid conducted to the heating element into aerosol which can be sucked by a user.
