In one embodiment of the liquid mist filtering smoking article of fig. 2-a, the liquid mist filtering smoking article further comprises a user interface, a main control chip, and a motor.

The user inputs the required mixed smoke included angle through the user interface, and the information is transmitted to the main control chip.

The main control chip obtains the current position data of the motor rotor through encoder data/position sensor data/multiple position correction. The main control chip compares the current position of the motor rotor with the included angle beta input by a user so as to obtain the driving data of the motor. The motor is linked with the gear structure so as to drive the liquid fog generating device to rotate, thereby adjusting the included angle beta between the smoke gas entering direction and the liquid fog entering direction.

In one embodiment of the liquid mist filtering smoking article, the liquid mist filtering smoking article comprises a flue gas inlet, a liquid mist generating device, a mixing chamber, a flue gas outlet and a control system.

The flue gas inlet is communicated with the mixing chamber, and the flue gas enters the mixing chamber from the flue gas inlet; the flue gas outlet is communicated with the mixing chamber; the liquid fog generating device is communicated with the mixing chamber; the liquid fog and the smoke generated by the liquid fog generating device are mixed in the mixing chamber and then flow out of the smoke outlet to filter the smoke.

The control system is used for receiving an instruction of a user side and controlling the liquid mist filtering smoking set to normally operate according to the instruction. The control system comprises a direct current voltage stabilizing circuit, a filter circuit, a main control chip, a DC-AC conversion resonance circuit and a feedback sampling circuit.

For the application environment of power supply of the low-voltage energy storage element, for example, a single battery is adopted for power supply, and when the working voltage of the control end of the DC-AC conversion resonance circuit is 5V, the direct-current voltage stabilizing circuit raises the voltage to 5V (a main control chip controls whether the direct-current voltage stabilizing circuit starts to work or not). The purpose of setting up voltage stabilizing circuit is in order to go out fog steadily, if do not set up voltage stabilizing circuit, also can reach the atomizing effect, but atomizing volume or atomizing injection dynamics during atomizing can change along with voltage variation.

The control system can control the fog output of the liquid fog generating device by changing the voltage, the current and/or the duty ratio of the liquid fog generating device.

As shown in fig. 3-a, when the control system controls the mist output of the liquid mist generating device by changing the voltage of the liquid mist generating device, the control system further comprises a voltage adjusting circuit.

The output of the direct current voltage stabilizing circuit is connected to the voltage adjusting circuit. The main control chip adjusts the output voltage of the voltage adjusting circuit according to the requirement or the setting of a user. The output voltage of the voltage adjusting circuit is filtered by the filter circuit and then is sent to the DC-AC conversion resonant circuit. The main control chip outputs a PWM signal to modulate the DC-AC conversion resonant circuit, the DC-AC conversion resonant circuit outputs a stable alternating current signal by combining a feedback signal of the feedback sampling circuit, and the output alternating current signal drives an atomizing sheet in the liquid mist generating device to atomize the atomized liquid to form filtered liquid mist.

As shown in fig. 3-B, when the control system controls the mist output of the liquid mist generating device by changing the current of the liquid mist generating device, the control system further comprises a current sampling circuit.

The output of the direct current voltage stabilizing circuit is connected to the current sampling circuit. The current sampling circuit samples the current value in real time, integrates the current value and sends the obtained integral value to the main control chip. And the main control chip compares the integral value with a set and adjusted current threshold value, and when the integral value is greater than or equal to the threshold value, the main control chip controls the working state of the direct current voltage stabilizing circuit or the DC-AC conversion resonant circuit to regulate the current. The output voltage of the current sampling circuit is filtered by the filter circuit and then is sent to the DC-AC conversion resonant circuit. The main control chip outputs a PWM signal to modulate the DC-AC conversion resonant circuit, the DC-AC conversion resonant circuit outputs a stable alternating current signal by combining a feedback signal of the feedback sampling circuit, and the output alternating current signal drives an atomizing sheet in the liquid mist generating device to atomize the atomized liquid to form filtered liquid mist.

As shown in fig. 3-C, when the control system controls the mist output of the liquid mist generating device by changing the duty ratio of the liquid mist generating device, the output of the dc voltage stabilizing circuit is connected to the filter circuit for filtering, so that the voltage is more stable. The control system also includes a resonant drive chip.

Constant voltage power supply, filter circuit, DC-AC conversion resonant circuit, atomizing piece, resonance drive chip, feedback sampling circuit cooperate and accomplish the atomizing function (hereinafter referred to as atomizing module), and atomizing module has two inputs: the power supply signal input by the filter circuit and the atomization module control signal output by the main control chip. When the atomization module works, firstly, the DC-AC conversion resonant circuit is matched with a modulation signal of the resonance driving chip to convert direct current voltage into an alternating current signal, the resonance driving chip is combined with DC-AC conversion resonant circuit information fed back by the feedback sampling circuit to adjust the resonance driving signal, so that the DC-AC conversion resonant circuit outputs a stable alternating current signal, and the output alternating current signal drives an atomization sheet in the liquid fog generating device to atomize atomized liquid to form filtered liquid fog.

When the liquid mist power needs to be adjusted, the main control chip modifies the output duty ratio signal, controls the direct current voltage stabilizing circuit or the atomization module to work intermittently, and adjusts the average power value in unit time.

As shown in fig. 4-a, the inputs to the control system are broadly divided into circuit inputs and material inputs.

Inputting materials: the main working mode of the liquid-mist filtering smoking set is to filter and absorb smoke of the traditional cigarette through atomized liquid. Thus, there are two parts of the input of the substance, one being cigarette smoke; and the other is a liquid mist.

The circuit inputs: including liquid mist components, filtration modes, smoke related signals, and the like.

The filtering mode refers to that after the flue gas and the liquid mist are mixed, the mixed gas needs to be subjected to primary gas-liquid separation treatment at the front end of the suction nozzle, the parameters can be determined through user input, or an identification chip is additionally arranged on a gas-liquid separation assembly, and the separation type is automatically identified during assembly.

The liquid mist component is the type of the liquid mist generating agent, and the proper different bases to be atomized, such as essence and the like, are independently selected by consumers.

The parameters to be controlled for the liquid mist output include the particle size of the liquid mist, the atomizing power, the spraying direction of the liquid mist, the components of the liquid mist and the like.

The particle size and power of the liquid mist can be controlled by the electrical parameters of the atomizing element, at present, three main atomizing modes, namely ultrasonic atomization, spraying and pressure atomization, are mainly adopted, and the voltage, the frequency, the duty ratio and the like are adjusted through a circuit system according to input; the liquid fog spraying direction can be realized by converting a position sensor into an electric signal. The liquid mist component is suitable for different substrates to be atomized, such as essence and the like, which are independently selected by consumers.

When cigarette smoke is input, besides material input, information carried by the cigarette smoke needs to be input as a circuit.

As shown in fig. 4-B, the physical quantities covered by the smoke signal input by the circuit include: the type of cigarette, the capacity of single-mouth suction, the flow rate of smoke, the direction of smoke entering the mixing cavity and the like. The cigarette types can be divided in two ways, one is by using brands, the other is by using main raw materials of the cigarettes (such as cut leaves, cut stems, thin slices and the like), and the parameters can be input into a control system of a smoking set in advance by a user or cigarette information (such as cigarette LOGO, bar codes, two-dimensional codes and the like) can be automatically identified by an appliance; when the single-mouth suction capacity and the smoke flow rate can be sucked by a consumer, the flow sensor attached to the smoking set receives and converts the smoke flow into an electric signal to be input; the direction of the airflow may be converted to an electrical signal by a position sensor or the like.

After the input enters the circuit system, the corresponding electric signal is calculated by the circuit system to control the output of the liquid fog.

Fig. 4-C shows an embodiment of a control system, wherein the control system includes a main control chip, an input module, an output module, and an atomization circuit module.

The atomization circuit module is connected with an atomization sheet in the liquid fog generation device to form a complete atomization function, so that the target substance is atomized.

The working principle of the atomizing sheet is briefly described as follows: the atomization piece consists of a piezoelectric ceramic piece and a metal film, and the metal film is perforated in a micron-sized mode through means such as laser; when an alternating signal is applied to the piezoelectric ceramic sheet, the piezoelectric ceramic can vibrate back and forth, and water molecules are extruded from the micropores of the metal film to form liquid mist.

The control steps of the control system are as follows:

firstly, an input module obtains input information in a cigarette preparation state;

secondly, the input module obtains input information of the cigarette in the ignition state;

the main control chip generates a control signal, and the atomization circuit module starts atomization;

the input module updates the input information;

fifthly, the control system adjusts the control signal according to the input information obtained in the fourth step and updates the control signal to the atomization circuit module;

sixthly, repeating the step five until the operation is finished.

The control system can calculate the electric signal to be controlled by a system table look-up or an empirical function. When the control system uses the system table look-up mode, the main control chip stores the corresponding table of the input information and the control signal.

As shown in fig. 4-D, the specific workflow of the control system in one embodiment is as follows:

after the liquid mist filtering smoking set is started, the input module obtains the type of the liquid mist generating agent and the type of the cigarette, the liquid mist generating agent is used as an X axis, the type of the cigarette is used as a Y axis, and the initial atomizing electric power is found through a two-dimensional table look-up method, as shown in table 2:

TABLE 2

When the user uses the n-type cigarette and selects the liquid mist generating agent 3, the control system selects the P3n as the atomizing initial power through the table look-up.

The system starts atomization, the system monitors parameters of smoke moisture parameters, smoke temperature and smoke quantity in real time, then the table lookup (cigarette type VS liquid mist generating agent table) is also adopted to obtain the value of the electricity for correction of positive electricity, the main control chip outputs the adjusted atomization electric power to the atomization control module, and the process is repeated until the smoke parameters with the best taste in the setting are obtained or until the operation is finished.

Finally, the filtered smoke with the key parameters compounded and expected is output, the experience level of consumers is improved, and the individual requirements of the consumers are met.

In one embodiment of the liquid mist filtering smoking article, the liquid mist filtering smoking article comprises a flue gas inlet, a liquid mist generating device, a mixing chamber, a flue gas outlet, and an operation monitoring system.

The flue gas inlet is communicated with the mixing chamber, and the flue gas enters the mixing chamber from the flue gas inlet; the flue gas outlet is communicated with the mixing chamber; the liquid fog generating device is communicated with the mixing chamber; the liquid fog and the flue gas generated by the liquid fog generating device are mixed in the mixing chamber, and then the mixed flue gas flows out from the flue gas outlet.

The operation monitoring system is used for monitoring the operation parameters of the liquid mist filtering smoking set so as to ensure the safe operation of the liquid mist filtering smoking set. The operation monitoring system can include main control chip, atomizing circuit and liquid level detection circuit, and main control chip is connected with liquid level detection circuit and atomizing circuit.

The atomization circuit module can comprise a filter circuit, a DC-AC resonance circuit and a resonance driving chip, and is connected with an atomization sheet in the liquid fog generating device to control the atomization sheet to work.

When the liquid level sensor is a liquid level probe sensor, the position of the liquid level sensor is close to the atomizing sheet as much as possible.

The main control chip monitors the feedback signal sent by the liquid level sensor in real time and compares the feedback signal with a preset liquid shortage threshold value, and when the atomization liquid amount is judged to be insufficient, the main control chip closes the atomization block through a control signal.

The liquid fog filtering smoking set also comprises an output module, the output module is connected with the main control chip, and the output module is used for feeding back the abnormal operation condition of the liquid fog filtering smoking set to a user.

Fig. 6 shows a preferred embodiment of a liquid mist filtering smoking set, the atomization circuit module of which further comprises a feedback sampling circuit, and the operation monitoring system of which further comprises a power supply sampling circuit.

The feedback sampling circuit is used for detecting the real-time atomization amount of the liquid fog generating device. The main control chip carries out time integration on the received atomization amount, compares the integral value with a preset liquid shortage threshold value, and reduces the atomization power of the atomization circuit module through a control signal when the integral value is lower than the liquid shortage threshold value.

The power supply sampling circuit is connected with the main control chip and is used for monitoring the power supply voltage input to the atomization circuit module in real time. When the power supply voltage received by the main control chip is lower than the preset undervoltage threshold value, the main control chip closes the atomization circuit module through a control signal.

It is understood that the above-mentioned liquid level detection, atomization amount detection and power supply detection can be used in combination or independently.

As shown in fig. 7-a, the smoke inlet 1 can be an elastic cigarette holder, which is integrally formed, and in fact, various features can be disassembled into parts, and an integral assembly is formed by an assembling manner to complete the function, which is described here in a state of a single part.

The elastic cigarette support 700 comprises a cigarette bin 701, a base 702 and an elastic flue 703. The cigarette cabin 701 and the base 702 are connected with two ends of the elastic channel 703 so as to form a through channel inside the elastic cigarette support.

The cigarette bin 701 is positioned at the front end of the elastic cigarette support and used for inserting cigarettes. The inner diameter of the cigarette bin is matched with the diameter of the cigarette, and in order to ensure air tightness, the inner diameter of the cigarette bin is slightly smaller than the diameter of the cigarette. The material of the cigarette chamber can be hard materials, such as hard plastics or metal; the material of the cigarette bin can also be soft material, such as silica gel or rubber. If the cigarette bin is made of soft materials, a sealing ring 705 is preferably arranged on the inner side or the outer side part of the front end of the cigarette bin and used for preventing smoke from leaking out of the front end of the elastic cigarette support, and because the contact part of the cigarette and the cigarette bin is a soft filter tip, if the cigarette and the soft cigarette bin are matched, the risk of air leakage is easily caused. The sealing ring is a hard material, such as plastic.

One or more poking sheets 704 are arranged on the outer side of the cigarette bin, so that a user can conveniently poke the elastic cigarette support, and the cigarette bin can quickly displace under the elastic action of the elastic flue, so that cigarette ash can be shaken off.

The base 702 is located at the tail end of the elastic cigarette support and is used for connecting with a smoking set to fix the elastic cigarette support on the smoking set main body. The base is provided with a fixing buckle used for matching with a smoking set to fix the elastic cigarette support. The base is made of elastic material and is in interference fit with the mounting hole of the smoking set.

The base is provided with an axial positioning 707 in front of the fixed buckle, the outer diameter of the axial positioning 707 is larger than the inner diameter of the mounting hole on the smoking set, and the axial positioning 707 is used for limiting the mounting depth of the elastic cigarette support. The axial positioning is provided with a circumferential positioning 708 for limiting the mounting direction of the elastic cigarette support, so as to ensure that the angle of the shifting sheet is suitable for the user to use.

The elastic flue 703 is a hollow pipe made of elastic material and used for connecting the cigarette chamber 701 and the base 702. The elastic flue has a certain curvature, so that the cigarette bin can generate certain displacement relative to the base when the user stirs the cigarette bin. The hardness of the elastic material is between 40 and 70 degrees. The elastic material can be one or more of silica gel or rubber. The length of the elastic flue can be adjusted according to hardness, and the cigarette bin can be quickly rebounded after the shifting piece is shifted.

As shown in fig. 7-B, the inner diameter of the cigarette bin 701 is larger than the inner diameters of the base 702 and the elastic channel 703, and a circular hollow positioning platform 709 is formed at the bottom end inside the cigarette bin due to the difference of the inner diameters, so that cigarettes are prevented from entering the elastic flue, and the cigarettes are prevented from affecting the deformation of the elastic flue.

During the use, the cigarette props up and inserts normal suction in the cigarette storehouse, when needing to shake off cigarette ash, the plectrum is stirred to direct finger with the hand that grips the utensil, makes the cigarette storehouse produce certain quick displacement, makes cigarette ash shake off, and the elasticity effect makes the cigarette storehouse resume the position originally after the pine hand, uses this kind of cigarette ash shake off device, can shake off cigarette ash generally like conveniently very much, and the one-hand operation avoids cigarette ash to scatter everywhere and pollute all around the environment.

The smoke outlet is provided with a gas-fog separating device 8, and as the mixed smoke which directly flows out from the smoke outlet 4 after the liquid fog and the smoke are mixed in the mixing chamber 3 can contain more liquid-fog components, the gas-fog separating device 8 can be arranged to further separate and filter the liquid-fog components in the smoke.

Fig. 8-a illustrates one embodiment of an aerosol separation device, aerosol separation device 800A including a filtering separation structure. The aerosol separation device 800A is mainly composed of three parts, namely a separator cover 801A, a separator housing 802A and a filtering separation structure 803A. The gas-mist separation device 800A may be air-tightly attached to the gas outlet 4 of the liquid-mist filtering smoking set by a first seal 804A on the separator cover 801A, and the first seal 804A may be an O-ring. The separator cover 801A and the separator housing 802A are sealed and fixed by a second sealing ring 805A to maintain the air tightness of the aerosol separation device 800A, and the second sealing ring 805A may be an O-ring, or may be sealed and fixed by a screw thread, a flange, or the like, so as to be easily detached or cleaned. Separator cover 801A cooperates with separator housing 802A to support and secure filtering separation structure 803A.

The bottom of the separator housing 802A is provided with a first air inlet 806A, the separator cover 801A is provided with a smoke path 809A which is axially through, two ends of the smoke path 809A are respectively provided with a second air inlet 807A and an air outlet 808A, mixed smoke formed by mixing liquid mist and smoke in the mixing chamber 3 can enter the aerosol separation device 800A through the first air inlet 806A, after the mixed smoke passes through the filtering and separating structure 803A, a part of water can be filtered by the filtering and separating structure 803A, after being condensed into water drops, the part of liquid mist can flow back to the mixing chamber 3 through the air inlet 806A, and after entering the second air inlet 807A, the smoke passing through the filtering and separating structure 803A flows out from the air outlet 808A along the smoke path 809A, and finally flows to the suction nozzle 7 and is sucked by a consumer.

The filtering and separating structure 803A is made of a filtering and absorbing material, and may be a porous and air-permeable material, such as a sponge, a porous ceramic, a metal mesh, a non-metal mesh, a waterproof and air-permeable membrane, and the like, and the pore diameter parameters of the material may be selected as required.

When the gas mist separator 800A needs to be cleaned, the gas mist separator 800A is simply removed from the liquid mist filtering smoking set, the separator cover 801A and the separator case 802A are separated and cleaned, and the absorbing filter material 803A may be replaced or cleaned.

Fig. 8-B and 8-C illustrate one embodiment of an aerosol separation device, the aerosol separation device 800B including a collision separation structure. The gas-mist separation device 800B is mainly composed of three parts, namely a separator cover 801B, a separator housing 802B and a collision separation structure 803B. The gas-mist separation device 800B may be air-tightly attached to the gas outlet 4 of the liquid-mist filtering smoking set by a first seal 804B on the separator cover 801B, and the first seal 804B may be an O-ring. The separator cover 801B and the separator housing 802B are sealed and fixed by a second sealing ring 805B to maintain the air tightness of the aerosol separation device 800B, and the second sealing ring 805B may be an O-ring, and may be sealed and fixed by a thread, a flange, or the like, so as to be convenient for disassembly or cleaning. The collision separation structure 803B is connected to the lower side of the separator cover 801B, and the two may be integrally formed or may be detachably connected.

The bottom of the separator housing 802B is provided with a first air inlet 806B, the separator cover 801B is provided with a flue gas path 809B which axially penetrates through, and two ends of the flue gas path 809B are respectively provided with a second air inlet 807B and an air outlet 808B.

The collision separating structure 803B has a plurality of collision baffle groups arranged on one support rod in an axially uniform distribution, 4 layers in the embodiment of fig. 8-C, a plurality of baffles 810B uniformly distributed in the circumferential direction in each collision baffle group, 3 in the embodiment of fig. 8-C, and vent holes 811B formed between the baffles 810B. The baffles on the two adjacent layers of collision baffle plate groups are distributed in a staggered manner, namely the vent holes of one layer of collision baffle plate group face the baffles of the next layer of collision baffle plate group when viewed from the axial direction. The position and shape of the baffle and the vent holes in each layer of collision baffle group and the number of the collision baffle groups can be designed differently. After the baffle plates are separated by collision for many times, the moisture in the smoke can be controlled to a more appropriate value, the more the number of the collision baffle plate groups is, the larger the shielding area of the baffle plates is, and the better the gas-mist separation effect is. The interval between the collision baffle group can be adjusted according to actual needs, and the adjustment of interval influences final aerial fog separation effect and suction difficulty degree, and the bigger the interval the aerial fog separation effect is worse, but the suction is easier, otherwise, the smaller the interval the aerial fog separation effect is better, but the suction is more difficult, and general interval is not less than 1 mm.

The outer edge of baffle 810B can substantially conform to the inner wall of separator housing 802B so that flue gas does not substantially flow through the gap between baffle 810B and separator housing 802B, but rather flows in a serpentine pattern along the gap between vent hole 811B and the set of impingement baffles.

The mixed smoke formed by mixing the liquid mist and the smoke in the mixing chamber 3 can enter the aerosol separation device 800B through the first air inlet 806B. When the mixed flue gas passes through the collision separation structure 803B, the moisture in the mixed flue gas cannot flow through the collision baffle 810B due to its high density, and is easily condensed into liquid drops to be attached to the baffle 810B, and finally flows back to the mixing chamber 3 through the air inlet 806A. Due to the low density of the smoke, after hitting the baffle 810B, the smoke can flow from the vent hole 811B to the second air inlet 807B by bypassing the baffle 810B, and after entering the second air inlet 807B, the smoke flows out from the air outlet 808B along the smoke path 809B, and finally the filtered smoke flows to the mouthpiece 7 and is sucked by the consumer.

When the gas mist separator 800B needs to be cleaned, the gas mist separator 800B is simply taken out of the liquid mist filtering smoking set, and the separator cover 801B and the collision separation structure 803B are taken out and cleaned.

Fig. 8-D and 8-E illustrate one embodiment of an aerosol separation device, the aerosol separation device 800D including a centrifugal separation structure. The gas-mist separation device 800D is mainly composed of three parts, namely a separator cover 801D, a separator housing 802D, and a centrifugal separation structure 803D. The gas-mist separation device 800D may be air-tightly attached to the gas outlet 4 of the liquid-mist filtering smoking set by a first seal 804D on the separator cover 801D, and the first seal 804D may be an O-ring. The separator cover 801D and the separator housing 802D are sealed and fixed by a second sealing ring 805D to maintain the air tightness of the aerosol separation device 800D, and the second sealing ring 805D may be an O-ring, and may be sealed and fixed by a thread, a flange, or the like, so as to be convenient to detach or clean. Centrifugal separation structure 803D is connected to the bottom of separator cover 801D, and may be integrally formed with or detachably connected to the same.

The bottom of the separator housing 802D is provided with a first air inlet 806D, the separator cover 801D is provided with a flue gas path 809D which axially penetrates through, and two ends of the flue gas path 809D are respectively provided with a second air inlet 807D and an air outlet 808D.

Centrifugal separation structure 803D has a helical baffle 810D mounted on support bar 811D, in the embodiment of fig. 8-D, helical baffle 810D has 3 turns around support bar 811D. Spiral baffle 810D's pitch and spiral number of turns all can adjust as required, and the adjustment of pitch and spiral number of turns influences final aerial fog separation effect and suction degree of difficulty, and the big aerial fog separation effect of pitch is poor the more but the suction is easier, and the spiral number of turns is more the separation effect is better but the suction is difficult more, and general pitch is not less than 1 mm.

The outer edge of the spiral baffle 810D can substantially completely conform to the inner wall of the separator housing 802D so that flue gas does not substantially flow through the gap between the spiral baffle 810D and the separator housing 802D, and flue gas can only flow along the spiral upward gas flow path inside the spiral baffle 810D.

The mixed smoke formed by mixing the liquid mist and the smoke in the mixing chamber 3 can enter the aerosol separation device 800D through the first air inlet 806D. During use, when the mixed flue gas passes through the centrifugal separation structure 803B, the flue gas and moisture are separated due to the centrifugal action, and liquid droplets are condensed on the spiral baffle 810D or the inner wall of the separator housing 802D and finally flow back to the mixing chamber 3 through the gas inlet 806A. The smoke can pass through the spiral baffle 810D along the airflow path, continue to flow into the second air inlet 807D, and flow out of the air outlet 808D along the smoke path 809D after entering the second air inlet 807D, and finally flow to the mouthpiece 7 and be inhaled by the consumer.

When the gas mist separation device 800D needs to be cleaned, the gas mist separation device 800D is simply taken out of the liquid mist filtering smoking set, and the separator cover 801D and the centrifugal separation structure 803D are taken out and cleaned.

Fig. 8-F and 8-G illustrate one embodiment of an aerosol separation device, aerosol separation device 800F comprising a centrifugal separation structure, consisting essentially of two parts, a separator cover 801F and a separator housing 802F, respectively. The gas-mist separator 800F may be air-tightly attached to the gas outlet 4 of the liquid-mist filtering smoking set by a first seal 804F on the separator cover 801F, and the first seal 804F may be an O-ring. The separator cover 801F and the separator housing 802F are sealed and fixed by a second sealing ring 805F to maintain the air tightness of the aerosol separation device 800F, and the second sealing ring 805F may be an O-ring, and may be sealed and fixed by a thread, a flange, or the like, so as to be convenient for disassembly or cleaning.

The separator cover body 801F and the separator housing 802F form a tapered space inside, the tapered space has a larger first end portion and a smaller second end portion, a first air inlet 806F is formed in the side wall of the first end portion along the tangential direction, an air guide column 811F is arranged on the end wall of the separator cover body 801F close to the first end portion along the axial direction, an air inlet end of the air guide column 811F extends towards the bottom of the tapered space to form a second air inlet 807F, an air outlet end of the air guide column 811F extends towards the end wall of the first end portion to form an air outlet 808F, and a flue gas path 809F is formed in the middle of the air guide column 811F.

The mixed smoke formed by mixing the liquid mist and the smoke in the mixing chamber 3 can enter the gas-mist separation device 800F through the first gas inlet 806F, and because the smoke has a certain initial velocity, the smoke is in a spiral flowing state under the action of the outer edge of the gas guide column 811F and the inner wall of the conical space of the separator shell 802F, and at the moment, part of the mixed smoke is condensed on the inner wall of the separator shell 802F under the centrifugal action. Since the second air inlet 807F is below and opens downward, the flow of the mixed flue gas is rotating downward, and the condensed moisture will flow to the bottom of the separator housing 802F under the combined action of gravity. When the mixed flue gas enters the gas guide column 811F from the bottom of the conical space, the direction of the gas flow is turned by about 180 degrees, and most of the water is condensed at the bottom of the conical space under the action of inertia due to the higher density of the residual water. The smoke enters the second air inlet 807F and exits the air outlet 808F along the smoke path 809F and ultimately flows to the mouthpiece 7 for consumption by the consumer.

When the gas mist separation device 800F needs to be cleaned, the gas mist separation device 800F is simply taken off from the liquid mist filtering smoking set, and the separator cover 801F is taken out and cleaned.

In one embodiment, the aerosol-separating device may comprise at least two different aerosol-separating structures selected from a filtering-separating structure, an impingement-separating structure, and a centrifugal-separating structure. The two different aerosol separation structures can be in parallel connection or in series connection. Two different aerosol separation structures may also be combined, for example a baffle for collision separation in the airflow path of the centrifugal separation structure.

The backflow prevention structure comprises a waste liquid channel 901A connecting the waste liquid cavity 904A and the mixing chamber 3, wherein the passing area of the waste liquid channel 901A close to the first opening 902A of the mixing chamber 3 is significantly larger than that of the second opening 903A at the other end, and preferably, the passing area of the first opening 902A is at least 2 times that of the second opening 903A. When the liquid mist filtering smoking set is placed vertically, the waste liquid in the mixing chamber 3 easily flows into the waste liquid channel 901A through the first opening 902A with a large area and flows into the waste liquid chamber 904A from the second opening 903A. When the liquid mist filtering smoking set is inclined or even inverted due to carrying vibration, the waste liquid in the waste liquid chamber 904A hardly flows into the waste liquid channel 901A through the second opening 903A with a small area and flows back to the mixing chamber 3 from the first opening 902A.

The waste liquid collection device 900B is removably mounted to the liquid mist filtering smoking set for cleaning or replacement. Fig. 9-E show the state when the waste liquid collecting device 900B is attached to the liquid mist filtering smoking set body. The upper part of the outer side of the shell 906B is provided with a threaded sealing port 909B, a first sealing strip 910B is arranged above the cover body 908B, and when the waste liquid collecting device 900B is screwed into the liquid mist filtering smoking set body by using threads and is installed in place, the first sealing strip 910B on the cover body 908B is matched with the liquid mist filtering smoking set body to form sealing.

The cover 908B may be sealingly connected to the housing 906B by a second circumferentially disposed sealing bead 912B to ensure sealing. A second bead 912B may be disposed on the outside of the cover 908B and/or inside the housing 906B, with fig. 9-D illustrating an embodiment in which the second bead 912B is disposed on the outside of the cover 908B. The cover 908B may be rigid or flexible, and a preferred embodiment is made of a soft material such as silicone rubber.
