Description

Technical Field

[0001] This patent relates to the field of new tobacco technology, and particularly to a liquid mist filtering smoking device. Background Art

[0002] In recent years, with the increasing attention to health, people have realized that traditional cigarettes are harmful to health to a certain extent, and the impact of traditional cigarettes on health and the environment has gradually attracted the attention of countries around the world.

[0003] It has become a consensus at home and abroad that smoking is harmful to health. Since harmful components such as tar in cigarette smoke are water-soluble to a certain extent, water can be used as a filtering medium to achieve the purpose of reducing tar and harm. At present, there are various water pipe smoking devices on the market that use liquid water to filter cigarette smoke, that is, when smoking a cigarette, the smoke first passes through water and then is inhaled by the human body. This smoking method enables many harmful components in the smoke to be filtered by the liquid to reduce the harm to the human body.

[0004] However, in such smoking devices, the smoke passes through water in a bubble state, and only the harmful components in the smoke on the surface of the bubbles are absorbed by the water, and a large amount of gas inside the bubbles does not come into contact with the water, so the adsorption effect is not sufficient.

[0005] Therefore, a liquid mist filtering smoking device that uses liquid mist to absorb harmful substances in the smoke to filter the smoke has emerged. The main mixing and filtering process of the liquid mist filtering smoking device is that the smoke airflow and the atomized liquid mist flow come into contact and mix with each other, and after filtering and absorbing some components in the original smoke, it is then inhaled by the consumer.

[0006] The liquid mist filtering smoking device involves a liquid passage and a circuit system. Without special treatment, the liquid mist is very likely to come into contact with the circuit system and damage the circuit system. Summary of the Invention

[0007] The purpose of the present invention is to protect the circuit in the liquid mist filtering smoking device, and to provide a brand-new liquid mist filtering smoking device with dry-wet separation, which can isolate the liquid mist and the circuit system.

[0009] A wet and dry separation liquid mist filtering smoking device, comprising a smoke inlet, a liquid mist generating device, a liquid storage chamber, a mixing chamber, a smoke outlet, a waste liquid collecting device and a control system. The smoke inlet is communicated with the mixing chamber, and smoke enters the mixing chamber from the smoke inlet; the smoke outlet is communicated with the mixing chamber; the liquid mist generating device is communicated with the mixing chamber; the liquid storage chamber is connected to the liquid mist generating device for providing atomizing liquid for the liquid mist generating device; after the liquid mist generated by the liquid mist generating device and the smoke are mixed in the mixing chamber, the mixed smoke flows out from the smoke outlet; the control system controls the operation of the liquid mist filtering smoking device, and the waste liquid collecting device is connected to the mixing chamber for collecting the waste liquid in the mixing chamber; the smoke inlet, the mixing chamber, the smoke outlet and the waste liquid collecting device form a liquid mist contact module; the liquid mist generating device and the control system form a liquid mist isolation module; there is only one connection port between the liquid mist contact module and the liquid mist isolation module, and the liquid mist generating device and the mixing chamber are connected through the connection port.

[0010] Further, components of the liquid mist contact module are sealed by a silicone rubber ring, a flange or a sealant.

[0011] Further, the liquid mist generating device is arranged at the connection port in a sealed manner.

[0012] Further, the sealing method includes silicone, a flange and / or a sealant.

[0013] Further, the liquid mist generating device has a one-way channel, and only when the liquid mist generating device is working, the liquid mist can enter the mixing chamber from the one-way channel.

[0014] Further, the liquid mist contact module and the liquid mist isolation module are arranged side by side.

[0015] Further, in the liquid mist contact module, the smoke inlet and the smoke outlet are arranged above the mixing chamber, and the waste liquid collecting device is arranged below the mixing chamber.

[0016] Further, the liquid mist isolation module includes a control chamber for accommodating the control system, and the control chamber and the liquid storage chamber are hermetically isolated from each other.

[0017] Further, the control chamber is provided with an electrically connected through hole, and the control system and the liquid mist generating device are electrically connected through the electrically connected through hole, and the electrically connected through hole is subjected to a sealing treatment.

[0018] Further, the liquid storage chamber is arranged above the liquid mist isolation module.

[0163] The detailed features and advantages of this patent will be described in detail in the following detailed implementation manners. The content is sufficient for any person skilled in the art to understand the technical content of this patent and implement it accordingly. And based on the specification, claims and drawings disclosed in this specification, those skilled in the art can easily understand the related purposes and advantages of this patent.

[0164] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0165] In the description of this embodiment, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this patent.

[0166] To make the purpose, technical solution and advantages of this patent clearer, the following will further describe the implementation manners of this patent in detail with reference to the drawings.

[0167] As Figure 1-A shown, the liquid mist filtering smoking device of this patent includes a smoke inlet 1, a liquid mist generating device 2, a mixing chamber 3, a smoke outlet 4, a liquid storage chamber 5, a control system 6, a nozzle 7, a gas-liquid separation device 8 and a waste liquid collection device 9.

[0168] The flue gas inlet 1 is communicated with the mixing chamber 3. One end of the filter tip of a traditional cigarette (not shown in the figure) can be inserted at the flue gas inlet 1. After the traditional cigarette is lit, the flue gas can enter the mixing chamber 3 from the flue gas inlet 1. In another embodiment, the flue gas at the flue gas inlet 1 can be generated by tobacco shreds, tobacco leaves, reconstituted tobacco, and other combustible materials containing nicotine or nicotine salts. The liquid mist generating device 2 is communicated with the mixing chamber 3. The liquid mist generating device 2 can atomize the atomizing liquid in the liquid storage chamber 5 to generate liquid mist and introduce it into the mixing chamber 3. The flue gas outlet 4 is communicated with the mixing chamber 3. After the liquid mist and the flue gas are mixed in the mixing chamber 3, the mixed flue gas flows out from the flue gas outlet 4. The control system 6 can be used to control the switch, the mist output amount, etc. of the liquid mist generating device 2. The flue gas outlet 4 is provided with a mouthpiece 7, and consumers can inhale the filtered flue gas through the mouthpiece 7. The flue gas outlet 4 is provided with a mist-gas separation device 8. Since there will be more liquid mist components in the mixed flue gas that directly flows out from the flue gas outlet 4 after the liquid mist and the flue gas are mixed in the mixing chamber 3, the mist-gas separation device 8 can be set to further separate the liquid mist components in the mixed flue gas. After the liquid mist and the flue gas are mixed in the mixing chamber 3 and separated by the mist-gas separation device 8, a considerable part of the liquid mist condenses into water droplets and flows to the bottom of the mixing chamber 3 to form waste liquid. A waste liquid collection device 9 is arranged below the flue gas mixing chamber 3, which is connected to the bottom of the flue gas mixing chamber 3 and is used to collect the waste liquid in the flue gas mixing chamber 3.

[0169] As Figure 1-B and Figure 1-C shown, in one embodiment, the liquid mist filtering smoking device includes a liquid mist contact module A and a liquid mist isolation module B. Figure 3 further illustrates the flow path and direction of the flue gas and the liquid mist between the modules through the modules and arrows.

[0170] Arrow ①: The original flue gas generated by the combustion of the traditional cigarette enters the mixing chamber 3 from the flue gas inlet 1.

[0171] Arrow ②: The waste liquid enters the waste liquid collection device 9 from the flue gas mixing chamber 3.

[0172] Arrow ③: The mixed flue gas after the liquid mist and the flue gas are mixed in the mixing chamber 3 enters the mist-gas separation device 8 at the flue gas outlet 4; a considerable part of the liquid mist condenses into water droplets in the mist-gas separation device 8 and flows back to the mixing chamber 3.

[0173] Arrow ④: The filtered flue gas enters the mouthpiece 7 at the flue gas outlet 4 and is sucked out.

[0174] Arrow ⑤: The liquid mist generating device 2 atomizes the atomizing liquid into liquid mist and sprays it into the flue gas mixing chamber 3.

[0175] Arrow ⑥: The atomizing liquid enters the liquid mist generating device 2 from the liquid storage chamber 5.

[0176] Since the liquid mist filtering smoking device involved in this patent involves a flue gas passage, a liquid passage, and an electric circuit, in order to ensure normal and safe use, it is necessary to reasonably arrange each module of such appliances. On the one hand, it is necessary to ensure the overall airtightness, and on the other hand, it is necessary to avoid contact between the flue gas and the liquid and the electric circuit, thereby damaging the control system 6 and reducing the service life of the smoking device. Therefore, it is necessary to reasonably design and arrange the passages indicated by the above arrows.

[0177] The liquid mist contact module A includes a flue gas inlet 1, a mixing chamber 3, a flue gas outlet 4, and a waste liquid collection device 9. The flue gas inlet 1 can be in interference fit with a traditional cigarette. Each component of the liquid mist contact module is sealed by a silicone ring, a flange, or a sealant to ensure airtightness. Each component through which the liquid mist flows forms a relatively airtight whole, effectively reducing the risk of liquid mist leakage.

[0178] The liquid mist isolation module B includes a liquid mist generating device 2 and a control system 6.

[0179] There is only one connection port (at the position of arrow ⑤) between the liquid mist contact module and the liquid mist isolation module. The liquid mist generating device 2 and the mixing chamber 3 are allowed to be connected to each other through this connection port. The liquid mist generating device is arranged at the connection port in a sealed manner, and the sealing methods include silicone, flange, or sealant. The liquid mist generating device 2 has a one-way channel. Only when the liquid mist generating device 2 is working, the liquid mist generated in the liquid storage chamber can enter the mixing chamber 3 in the liquid mist contact module A in the form of liquid mist through the one-way channel. The module in contact with the liquid mist and the module isolating the liquid mist are basically independently separated, with only one necessary connection port, effectively protecting the control system and extending the service life of the control system.

[0180] The liquid mist isolation module B can further include a control chamber for accommodating the control system 6. The control chamber and the liquid storage chamber 5 are sealed and isolated from each other, so as to ensure that the atomized liquid in the liquid storage chamber 5 will not flow into the control chamber, thereby damaging the control system 6. The control chamber is provided with an electrical connection through-hole. The control system 6 and the liquid mist generating device 2 are electrically connected through the electrical connection through-hole, and the electrical connection through-hole is sealed, including methods such as using a sealing ring or silicone filling.

[0181] The above-mentioned sealing and connection methods are very simple and easy for the reuse, replacement, and expansion of components.

[0182] Preferably, a flange seal is used between the mixing chamber 3 and the waste liquid collection device 9 (arrow ②).

[0183] Preferably, a flange seal is used at the installation connection between the aerosol separation device 8 (arrow ③) and the mouthpiece 7 (arrow ④).

[0184] Preferably, a cigarette holder is provided at the flue gas inlet 1, and a silicone seal is used between the cigarette holder and the mixing chamber 3.

[0185] Preferably, the liquid mist generating device is sealed with the connection port by silica gel.

[0186] Preferably, the liquid mist contact module A and the liquid mist isolation module B are arranged side by side. Preferably, in the liquid mist contact module A, the flue gas inlet 1 and the flue gas outlet 4 are arranged above the mixing chamber 3, and the waste liquid collection device 9 is arranged below the mixing chamber 3. Preferably, the liquid storage chamber 5 is arranged above the liquid mist isolation module B. These arrangements can be clearly seen from Figure 1-A 、 1-B and 1-C.

[0187] Figure 5-A Shown is the main body module of the liquid mist generating device. The main body module includes a mixing chamber 3, a liquid mist generating device 2, and a control system 6. The main body module provides the key functions of the liquid mist generating device: atomization filtration and control. The outer shell of the main body module can be integrated.

[0188] Figure 5-B Shown is the flue gas passage module of the liquid mist generating device. The flue gas passage module includes a flue gas inlet 1, a flue gas outlet 4, a nozzle 7, and an aerosol separation device 8. The flue gas before / after filtration passes in and out of the main body module through the flue gas passage module.

[0189] Figure 5-C Shown is the water storage module of the liquid mist generating device. The water storage module includes a liquid storage chamber 5 and a water storage cover. The water storage cover can be an internally threaded screw cap or a soft material (such as rubber) plug cap.

[0190] As Figure 5-D shown, the waste water collection module includes a waste liquid collection device 9 and a detachable valve (optional) at its bottom.

[0191] When the flue gas enters the mixing chamber and meets the liquid mist, an included angle is formed. The included angle can be changed by adding corresponding mechanical structures at the flue gas inlet and / or the liquid mist generating device. When the included angle is changed by the mechanical structure, the atomization effect will also change accordingly.

[0192] As Figure 2-A shown, in an embodiment of the liquid mist filtering smoking device, the liquid mist filtering smoking device is a liquid mist filtering smoking device with adjustable aerosol mixing angle, including a mixing chamber 201, a cigarette clamping member 202, a liquid mist generating device 203, a mixed flue gas outlet 204, a condensed waste liquid outlet 205, and a flue gas inlet 206.

[0193] The mixed flue gas outlet 204 is communicated with the mixing chamber 201 for the flue gas and the liquid mist to flow out after being mixed and filtered in the mixing chamber 201. The condensed waste liquid outlet 205 is communicated with the mixing chamber 201 for the waste liquid generated after the flue gas and the liquid mist are mixed and filtered to flow out.

[0194] The direction of the flue gas entering the mixing chamber 201 forms an angle β with the direction of the liquid mist entering the mixing chamber 201, and this angle β can vary.

[0195] The direction of the flue gas entering the mixing chamber 201 forms an angle β with the direction of the liquid mist entering the mixing chamber 201, and this angle β can vary.

[0196] The direction of the flue gas entering and the direction of the liquid mist entering can be in the same plane (as shown in Figure 2-A and Figure 2-B ), or can be in different planes (not shown, for example, in two planes parallel or non - parallel to each other).

[0197] Preferably, the direction of the flue gas entering and the direction of the liquid mist entering are substantially in the same plane. In this case, the angle β is preferably between 0° and 180°, and more preferably can be 90±10°. If the direction of the flue gas entering and the direction of the liquid mist entering are in different planes, a spatial angle β will be formed between them. Similarly, the angle β is preferably between 0° and 180°, and more preferably can be 90±10°.

[0198] The flue gas inlet 206 is in communication with the mixing chamber 201. The flue gas enters the mixing chamber 201 from the flue gas inlet 206, and the direction of the flue gas entering the mixing chamber 201 can be changed. The flue gas inlet 206 is provided on the cigarette clamping member 202, and the cigarette clamping member 202 is adjustably assembled on the mixing chamber 201. The direction of the flue gas entering changes with the adjustment of the cigarette clamping member 202.

[0199] Preferably, an installation chute is provided between the cigarette clamping member 202 and the chamber wall of the mixing chamber 201, allowing it to slide on the chamber wall of the mixing chamber 201 to change the angle of the flue gas entering direction.

[0200] Preferably, the cigarette clamping member 202 is adjusted by a mechanical lever or a motor drive.

[0201] Preferably, the flue gas inlet part is made of a soft material, such as a silicone tube, a latex tube or a gooseneck tube, etc. The direction of the flue gas entering is changed by bending the soft material.

[0202] The liquid mist generating device 203 is in communication with the mixing chamber 201. After the liquid mist generated by the liquid mist generating device 203 and the flue gas are mixed in the mixing chamber 201, the filtered flue gas flows out from the mixed flue gas outlet 204. The liquid mist generating device 203 is adjustably assembled on the mixing chamber 201, and the direction of the liquid mist entering changes with the adjustment of the liquid mist generating device 203.

[0203] Preferably, a mounting groove is provided between the liquid mist generating device 203 and the cavity wall of the mixing chamber 201, so that the liquid mist generating device 203 can slide on the cavity wall of the mixing chamber 201 to change the angle of the liquid mist entry direction.

[0204] Preferably, the liquid mist generating device 203 is adjusted by a mechanical lever or a motor drive.

[0205] Figure 2-B The arrows further illustrate that, in one embodiment, the flow direction of the smoke and liquid mist and the angle change direction of the angle-adjustable component.

[0206] Arrow a: direction of smoke entering the mixing chamber 201 .

[0207] Arrow b: direction in which the liquid mist enters the mixing chamber 201 .

[0208] Arrow c: the outflow direction of the mixed flue gas leaving the mixing chamber 201 .

[0209] Arrow d: direction in which waste liquid flows out of the mixing chamber 201 .

[0210] Arrow e: variable direction of the smoke channel.

[0211] Arrow f: variable direction of the liquid mist spray.

[0212] The angle between the flue gas inflow direction and the mixed flue gas outflow direction is α. The angle between the flue gas inlet direction and the liquid mist inlet direction is β.

[0213] Table 1 shows the key parameters of the final mixed smoke components when different β values (i.e. the angle between smoke and liquid mist) are selected when the physical parameters of cigarette smoke and liquid mist remain basically unchanged and the smoke entry direction and liquid mist entry direction are basically in the same plane:

[0214] Among them, for the data in Table 1, α is less than 30° (the outflow direction of the mixed flue gas is also in the same plane as the inflow direction of the flue gas and the inflow direction of the liquid mist).

[0215]

[0216] Table 1

[0217] From the data in Table 1, it can be seen that when the intersection angle between smoke and liquid mist is about 90°, the key indicators of smoke filtration are relatively good. That is, the tar, which is a harmful substance, is significantly reduced, and the nicotine content is relatively high. The actual smoking sensory experience is basically consistent with the data performance, that is, when the smoking device is arranged at an angle of 90° β, the smoking experience is better.

[0218] exist Figure 2-AIn an embodiment of the liquid mist filtering smoking device, the liquid mist filtering smoking device further includes a user interface, a main control chip, and a motor.

[0219] The user inputs the required included angle of the mixed flue gas through the user interface, and this information is transmitted to the main control chip.

[0220] The main control chip obtains the current position data of the motor rotor through encoder data / position sensor data / multiple position corrections. The main control chip compares the current position of the motor rotor with the included angle β input by the user to obtain the drive data of the motor. The motor is linked with the gear structure, thereby driving the liquid mist generating device to rotate, so as to adjust the included angle β between the flue gas inlet direction and the liquid mist inlet direction.

[0221] In the above process, the main control chip continuously detects the feedback readings of the encoder / position sensor until the liquid mist generating device rotates to the position of the required included angle of the mixed flue gas input by the user, and then the main control chip stops and locks the motor.

[0222] In an embodiment of the liquid mist filtering smoking device, the liquid mist filtering smoking device includes a flue gas inlet, a liquid mist generating device, a mixing chamber, a flue gas outlet, and a control system.

[0223] 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 mist generating device is communicated with the mixing chamber; after the liquid mist generated by the liquid mist generating device and the flue gas are mixed in the mixing chamber, the filtered flue gas flows out from the flue gas outlet.

[0224] The control system is used to receive instructions from the user terminal and control the normal operation of the liquid mist filtering smoking device according to the instructions. The control system includes a DC regulated power supply circuit, a filtering circuit, a main control chip, a DC-AC conversion resonance circuit, and a feedback sampling circuit.

[0225] The DC regulated power supply circuit is for the power supply application environment of low-voltage energy storage components. For example, when powered by a single battery and the operating voltage of the control end of the DC-AC conversion resonance circuit is 5V, the DC regulated power supply circuit raises the voltage to 5V (the main control chip controls whether the DC regulated power supply circuit starts to work). The purpose of setting the regulated power supply circuit is to produce mist stably. If the regulated power supply circuit is not set, the atomization effect can also be achieved, but the atomization amount or atomization spray force during atomization will change with the voltage.

[0226] The control system can control the mist output of the liquid mist generating device by changing the voltage, current, and / or duty cycle of the liquid mist generating device.

[0227] As Figure 3-A shown, 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 includes a voltage adjustment circuit.

[0228] The output of the DC regulated power supply circuit is connected to the voltage adjustment circuit. The main control chip adjusts the output voltage of the voltage adjustment circuit according to requirements or user settings. The output voltage of the voltage adjustment circuit is sent to the DC-AC conversion resonant circuit after being filtered by the filter circuit. The main control chip outputs a PWM signal to modulate the DC-AC conversion resonant circuit, and combines the feedback signal of the feedback sampling circuit to make the DC-AC conversion resonant circuit output a stable AC signal. The output AC signal drives the atomizing sheet in the liquid mist generating device to atomize the atomizing liquid to form filtered liquid mist.

[0229] As Figure 3-B shown, when the control system controls the mist output amount of the liquid mist generating device by changing the current of the liquid mist generating device, the control system further includes a current sampling circuit.

[0230] The output of the DC regulated power supply circuit is connected to the current sampling circuit. The current sampling circuit samples the current value in real time and integrates the current value, and sends the obtained integral value to the main control chip. The main control chip compares the integral value with the set and adjusted current threshold. When the integral value is greater than or equal to the threshold, the main control chip controls the working state of the DC regulated power supply circuit or the DC-AC conversion resonant circuit to adjust the current. The output voltage of the current sampling circuit is sent to the DC-AC conversion resonant circuit after being filtered by the filter circuit. The main control chip outputs a PWM signal to modulate the DC-AC conversion resonant circuit, and combines the feedback signal of the feedback sampling circuit to make the DC-AC conversion resonant circuit output a stable AC signal. The output AC signal drives the atomizing sheet in the liquid mist generating device to atomize the atomizing liquid to form filtered liquid mist.

[0231] As Figure 3-C shown, when the control system controls the mist output amount of the liquid mist generating device by changing the duty cycle of the liquid mist generating device, the output of the DC regulated power supply circuit is connected to the filter circuit for filtering to make the voltage more stable. The control system further includes a resonant drive chip.

[0232] The regulated power supply, filter circuit, DC-AC conversion resonant circuit, atomizing sheet, resonant drive chip, and feedback sampling circuit cooperate to complete the atomizing function (hereinafter referred to as the atomizing module). The atomizing module has two inputs: the power signal input by the filter circuit and the atomizing module control signal output by the main control chip. When the atomizing module works, first, the DC-AC conversion resonant circuit cooperates with the modulation signal of the resonant drive chip to convert the DC voltage into an AC signal. The resonant drive chip adjusts the resonant drive signal by combining the information of the DC-AC conversion resonant circuit fed back by the feedback sampling circuit, so that the DC-AC conversion resonant circuit outputs a stable AC signal. The output AC signal drives the atomizing sheet in the liquid mist generating device to atomize the atomizing liquid to form filtered liquid mist.

[0233] When it is necessary to adjust the liquid mist power, the main control chip modifies the output duty cycle signal to control the DC regulated power supply circuit or the atomization module to work intermittently, and adjusts the average power value per unit time.

[0234] In an embodiment of a liquid mist filtering smoking device, the liquid mist filtering smoking device includes a smoke inlet, a liquid mist generating device, a mixing chamber, a smoke outlet, and a control system. The smoke inlet is communicated with the mixing chamber, and smoke enters the mixing chamber from the smoke inlet; the smoke outlet is communicated with the mixing chamber; the liquid mist generating device is communicated with the mixing chamber; after the liquid mist generated by the liquid mist generating device and the smoke are mixed in the mixing chamber, the filtered smoke flows out from the smoke outlet; the control system is used to control the fogging form of the liquid mist generating device.

[0235] As Figure 4-A shown, the inputs of the control system in a broad sense are divided into circuit inputs and material inputs.

[0236] Material input: The main working mode of the liquid mist filtering smoking device is to filter and absorb the smoke of traditional cigarettes through the atomized liquid. Therefore, there are two parts of material input, one is cigarette smoke; the other is liquid mist.

[0237] Circuit input: It includes liquid mist components, filtering methods, and smoke-related signals, etc.

[0238] The filtering method refers to that after the smoke and the liquid mist are mixed, it is necessary to perform a gas-liquid separation treatment on the mixed vapor at the front end of the mouthpiece. This parameter can be determined by user input, or an identification chip can be attached to the gas-liquid separation component to automatically identify the separation type during assembly.

[0239] The liquid mist component is the type of liquid mist generator, and the consumer independently selects a suitable atomization matrix with different added flavors, etc.

[0240] The parameters that need to be controlled for the liquid mist output include the particle size of the liquid mist, the atomization power, the liquid mist injection direction, and the liquid mist components, etc.

[0241] The particle size and power of the liquid mist can be controlled by the electrical parameters of the atomization element. Currently, three main atomization methods are mainly adopted, namely ultrasonic, jet, and pressure atomization. The circuit system adjusts the voltage, frequency, duty cycle, etc. according to the input; the liquid mist injection direction can be realized by converting the position sensor into an electrical signal. The liquid mist component is selected by the consumer independently for a suitable atomization matrix with different added flavors, etc.

[0242] When the cigarette smoke is input, in addition to the material input, the information carried by it needs to be used as a circuit input.

[0243] As Figure 4-BAs shown, the physical quantities covered by the flue gas signal input to the circuit include: the type of cigarette, the volume of single puff, the flow rate of the flue gas, and the direction of the flue gas entering the mixing chamber, etc. There are two ways to classify cigarette types. One is to classify by brand, and the other is to classify by the main raw materials of the cigarette (such as cut tobacco, stem silk, sheet, etc.). The above parameters can be pre-input by the user to the control system of the smoking device, or the device can automatically identify the cigarette information (such as cigarette LOGO, barcode, QR code, etc.); the volume of single puff and the flow rate of the flue gas can be input by converting the signals received by the flow sensor attached to the smoking device when the consumer smokes into electrical signals; the airflow direction can be converted into an electrical signal by a position sensor, etc.

[0244] After the input enters the circuit system, the corresponding electrical signal is calculated by the circuit system to control the output of the liquid mist.

[0245] As Figure 4-C Shown is an embodiment of the control system. Among them, the control system includes a main control chip, an input module, an output module, and an atomization circuit module.

[0246] After receiving the input information from the input module, the main control chip converts the input information into a control signal. The main control chip drives the atomization circuit module according to the control signal to perform the corresponding atomization form and feedbacks the output information to the user through the output module.

[0247] The input module includes one or more of a touch screen, a keyboard, a knob, a switch, and a sensor, and is used to capture the input information of the user and transmit the information to the main control chip. The input information includes one or more of a power-on / off signal, a gear, a tobacco type, a liquid mist generating agent type, a moisture content of the flue gas, a temperature of the flue gas, a nicotine content, an air flow rate, an air flow velocity, and an air pressure.

[0248] The output module includes one or more of a display screen, an LED lamp, a motor, a voice module, and a buzzer, and is used to feedback the state of the system to the user. The output information includes one or more of a working state, a gear, a power quantity, a charging indication, an under-voltage prompt, a tobacco type, a liquid mist generating agent type, a moisture content of the flue gas, a temperature of the flue gas, a nicotine content, an air flow rate, an air flow velocity, and an air pressure.

[0249] The atomization circuit module includes a regulated power supply, a filter circuit, a DC-AC resonance circuit, a resonance drive chip, and a feedback sampling circuit. The atomization circuit module is connected to the atomization sheet in the liquid mist generating device to form a complete atomization function and realize the atomization of the target substance.

[0250] A brief description of the working principle of the atomization sheet: The atomization sheet is composed of a piezoelectric ceramic sheet and a metal film, and the metal film is perforated at the micron level by means of laser, etc.; when an alternating signal is applied to the piezoelectric ceramic sheet, the piezoelectric ceramic will vibrate reciprocally, and squeeze the water molecules out of the micropores of the metal film to form a liquid mist.

[0251] The control steps of the control system are as follows:

[0252] Step ①: The input module obtains the input information in the cigarette preparation state;

[0253] Step ②: The input module obtains the input information in the cigarette ignition state;

[0254] Step ③: The main control chip generates a control signal, and the atomization circuit module starts atomization;

[0255] Step ④: The input module updates the input information;

[0256] Step ⑤: The control system adjusts the control signal according to the input information obtained in Step ④ and updates it to the atomization circuit module;

[0257] Step ⑥: Repeat Step ⑤ until the end of this operation.

[0258] The control system can calculate the electrical signal to be controlled through system look-up tables or empirical function calculations. When the control system uses the system look-up table method, a corresponding table of input information and control signals is stored in the main control chip.

[0259] Such as Figure 4-D shown, the specific working process of the control system in an embodiment is as follows:

[0260] After starting the liquid mist filtering smoking device, the input module obtains the type of liquid mist generating agent and the type of cigarette. Taking the liquid mist generating agent as the X-axis and the type of cigarette as the Y-axis, the initial atomization electric power is found through the two-dimensional look-up table method, as shown in Table 2:

[0261]

[0262]

[0263] Table 2

[0264] When the user uses the n-type cigarette and selects the liquid mist generating agent 3, the control system selects P3n as the initial atomization power through look-up table.

[0265] The system starts atomization, and the system real-time monitors the parameters of flue gas moisture, flue gas temperature, and flue gas volume. Then, the corrected electric power value is also obtained by look-up table (here the cigarette type VS liquid mist generating agent table). The main control chip outputs the adjusted atomization electric power to the atomization control module, and repeats this process until the flue gas parameters with the best taste in the setting are obtained, or until the end of this operation.

[0266] Finally, the filtered flue gas with key parameters meeting the expectations is output, improving the consumer experience level and meeting the personalized needs of consumers.

[0267] In an embodiment of a liquid mist filtering smoking device, the liquid mist filtering smoking device includes a smoke inlet, a liquid mist generating device, a mixing chamber, a smoke outlet, and an operation monitoring system.

[0268] The smoke inlet is in communication with the mixing chamber, and smoke enters the mixing chamber from the smoke inlet; the smoke outlet is in communication with the mixing chamber; the liquid mist generating device is in communication with the mixing chamber; after the liquid mist generated by the liquid mist generating device and the smoke are mixed in the mixing chamber, the mixed smoke flows out from the smoke outlet.

[0269] The operation monitoring system is used to monitor the operation parameters of the liquid mist filtering smoking device to ensure the safe operation of the liquid mist filtering smoking device. The operation monitoring system may include a main control chip, an atomization circuit, and a liquid level detection circuit, and the main control chip is connected to the liquid level detection circuit and the atomization circuit.

[0270] The atomization circuit module may include a filtering circuit, a DC-AC resonance circuit, and a resonance driving chip, and the atomization circuit module is connected to the atomization sheet in the liquid mist generating device to control its operation.

[0271] The liquid level detection circuit may include a liquid level sensor. The liquid level sensor is one or several of a liquid level probe sensor, a laser sensor, a microwave sensor, an ultrasonic sensor, an optoelectronic sensor, a pressure sensor, or a capacitance sensor. When the liquid level sensor is a liquid level probe sensor, the position of the liquid level sensor is as close as possible to the atomization sheet.

[0272] 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 under-liquid threshold. When it is determined that the atomized liquid volume is insufficient, the main control chip closes the atomization block through a control signal.

[0273] The liquid mist filtering smoking device may further include an output module, and the output module is connected to the main control chip. The output module is used to feedback the abnormal operation condition of the liquid mist filtering smoking device to the user.

[0274] Figure 6 A preferred embodiment of a liquid mist filtering smoking device is shown, in which the atomization circuit module further includes a feedback sampling circuit, and its operation monitoring system further includes a power supply sampling circuit.

[0275] The feedback sampling circuit is used to detect the real-time atomization amount of the liquid mist generating device. The main control chip integrates the received atomization amount over time and compares the integrated value with a preset under-liquid threshold. When the integrated value is lower than the under-liquid threshold, the main control chip reduces the atomization power of the atomization circuit module through a control signal.

[0276] The power supply sampling circuit is connected to the main control chip, and the power supply sampling circuit is used to monitor 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 a preset under-voltage threshold, the main control chip closes the atomization circuit module through a control signal.

[0277] It can be understood that the above-mentioned liquid level detection, atomization amount detection and power supply detection can be used in combination or can be used separately.

[0278] like Figure 7-A As shown, the smoke inlet 1 can be an elastic cigarette holder, which is integrally formed. In fact, each feature can be disassembled into parts and assembled into an integral component to complete the function. The state of a single part is used here for explanation.

[0279] The elastic cigarette holder 700 includes a cigarette bin 701, a base 702 and an elastic smoke channel 703. The cigarette bin 701, the base 702 and the two ends of the elastic channel 703 are connected to form a through channel inside the elastic cigarette holder.

[0280] The cigarette bin 701 is located at the front end of the elastic cigarette holder and is used to insert cigarettes. The inner diameter of the cigarette bin matches the diameter of the cigarette. 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 bin can be a hard material, such as hard plastic or metal; the material of the cigarette bin can also be a soft material, such as silicone or rubber. If the cigarette bin is a soft material, a preferred solution is to provide a sealing ring 705 on the inner or outer part of the front end of the cigarette bin to prevent smoke from leaking from the front end of the elastic cigarette holder, because the part of the cigarette that contacts the cigarette bin is a soft filter. If it is matched with a soft cigarette bin, there is a risk of leakage. The sealing ring is a hard material, such as plastic.

[0281] One or more paddles 704 are provided on the outside of the cigarette bin, which are convenient for the user to pry the elastic cigarette holder, so that the cigarette bin can be quickly displaced due to the elastic effect of the elastic smoke duct, so as to shake off the cigarette ash.

[0282] The base 702 is located at the rear end of the elastic cigarette holder and is used to connect with the smoking device to fix the elastic cigarette holder to the main body of the smoking device. A fixing buckle is provided on the base to fix the elastic cigarette holder with the smoking device. The base is made of elastic material and has an interference fit with the mounting hole of the smoking device.

[0283] The base is provided with an axial positioning device 707 in front of the fixing buckle, and its outer diameter is larger than the inner diameter of the mounting hole on the smoking device, which is used to limit the installation depth of the elastic cigarette holder. The axial positioning device is provided with a circumferential positioning device 708, which is used to limit the installation direction of the elastic cigarette holder, so as to ensure that the angle of the pick is suitable for the user.

[0284] The elastic flue 703 is a hollow pipe made of elastic material and is used to connect the tobacco bin 701 and the base 702. The elastic flue has a certain degree of bendability, enabling the tobacco bin to generate a certain displacement relative to the base when the user toggles the tobacco bin. The hardness of the elastic material is between 40 and 70 degrees. The elastic material can be one or several of silicone or rubber. The length of the elastic flue can be adjusted according to the hardness to ensure that the tobacco bin can quickly rebound after the toggle piece is toggled.

[0285] As Figure 7-B shown, the inner diameter of the tobacco bin 701 is larger than the inner diameters of the base 702 and the elastic channel 703. A circular hollow positioning platform 709 is formed at the inner bottom end of the tobacco bin due to the inner diameter difference, preventing the cigarette from entering the elastic flue and ensuring that the cigarette does not affect the deformation of the elastic flue.

[0286] During use, the cigarette is inserted into the tobacco bin for normal suction. When it is necessary to shake off the ash, the user directly uses the fingers of the hand holding the appliance to toggle the toggle piece, causing the tobacco bin to generate a certain rapid displacement to shake off the ash. After releasing the hand, the tobacco bin returns to its original position due to the elastic effect. Using this kind of ash shaking device, it is very convenient to operate with one hand like usually shaking off ash, avoiding the ash from scattering everywhere and polluting the surrounding environment.

[0287] The flue gas outlet is provided with an aerosol separation device 8. Since the mixed flue gas with a large amount of aerosol components will directly flow out from the flue gas outlet 4 after the liquid mist and the flue gas are mixed in the mixing chamber 3, the aerosol separation device 8 can be set to further separate and filter the aerosol components in the flue gas.

[0288] Figure 8-A An embodiment of the aerosol separation device is shown. The aerosol separation device 800A includes a filtration and separation structure. The aerosol separation device 800A is mainly composed of three parts, namely a separator cover body 801A, a separator housing 802A, and a filtration and separation structure 803A. The aerosol separation device 800A can be hermetically installed on the flue gas outlet 4 of the liquid mist filtering smoking appliance through the first sealing ring 804A on the separator cover body 801A. The first sealing ring 804A can be an O-ring. The separator cover body 801A and the separator housing 802A are hermetically fixed through the second sealing ring 805A to maintain the airtightness of the aerosol separation device 800A. The second sealing ring 805A can be an O-ring. In addition, sealing and fixing methods such as threads and flanges can also be used, making it convenient for disassembly or cleaning. The separator cover body 801A and the separator housing 802A cooperate with each other to support and fix the filtration and separation structure 803A.

[0289] The bottom of the separator housing 802A is provided with a first air inlet 806A. The separator cover 801A has an axially penetrating flue gas path 809A. The two ends of the flue gas path 809A are respectively a second air inlet 807A and an air outlet 808A. The mixed flue gas formed after the liquid mist and the flue gas are mixed in the mixing chamber 3 can enter the aerosol separation device 800A through the first air inlet 806A. After the mixed flue gas passes through the filtration and separation structure 803A, part of the moisture will be filtered by the filtration and separation structure 803A, and part of the liquid mist will condense into water droplets and can flow back to the mixing chamber 3 through the air inlet 806A. The flue gas passing through the filtration and separation structure 803A enters the second air inlet 807A and then flows out from the air outlet 808A along the flue gas path 809A, and finally flows to the mouthpiece 7 and is inhaled by the consumer.

[0290] The filtration and separation structure 803A uses a filtration and absorption material, specifically, it can be a porous breathable material, such as sponge, porous ceramic, metal mesh, non-metal mesh, waterproof breathable membrane, etc. The pore size parameters of the material can be selected according to needs.

[0291] When the aerosol separation device 800A needs to be cleaned, only need to remove the aerosol separation device 800A from the liquid mist filtration smoking device, separate the separator cover 801A and the separator housing 802A, clean the two, and the absorption and filtration material 803A can also be taken out for replacement or cleaning.

[0292] Figure 8-B and Figure 8-C Fig. shows an embodiment of the aerosol separation device. The aerosol separation device 800B includes a collision separation structure. The aerosol separation device 800B mainly consists of three parts, namely a separator cover 801B, a separator housing 802B and a collision separation structure 803B. The aerosol separation device 800B can be airtightly installed on the flue gas outlet 4 of the liquid mist filtration smoking device through the first sealing ring 804B on the separator cover 801B. The first sealing ring 804B can be an O-ring. The separator cover 801B and the separator housing 802B are hermetically fixed through the second sealing ring 805B to maintain the airtightness of the aerosol separation device 800B. The second sealing ring 805B can be an O-ring. In addition, sealing and fixing methods such as threads and flanges can also be used, so as to facilitate disassembly or cleaning. The collision separation structure 803B is connected below the separator cover 801B, and the two can be integrally formed or connected by a detachable structure.

[0293] The bottom of the separator housing 802B is provided with a first air inlet 806B. The separator cover 801B has an axially penetrating flue gas path 809B. The two ends of the flue gas path 809B are respectively a second air inlet 807B and an air outlet 808B.

[0294] The collision separation structure 803B has a multi-layer collision baffle group evenly distributed axially on a support rod.Figure 8-C The embodiment in [it] has 4 layers, and a plurality of baffles 810B are evenly distributed in the circumferential direction for each layer of collision baffle group. Figure 8-C The embodiment in [it] has 3 [units]. Ventilation holes 811B are formed between the baffles 810B. The baffles on adjacent layers of collision baffle groups are staggeredly distributed. That is, from the axial direction, the ventilation holes of a certain layer of collision baffle group are directly opposite to the baffles of the next layer of collision baffle group. The positions, shapes of the baffles and ventilation holes in each layer of collision baffle group and the number of collision baffle groups can all have different designs. After multiple collisions and separations by the baffles, the moisture in the flue gas can be controlled to a more appropriate value. The more the number of collision baffle groups, the larger the shielding area of the baffles, and the better the aerosol separation effect. The distance between the collision baffle groups can be adjusted according to actual needs. The adjustment of the distance affects the final aerosol separation effect and the ease of suction. The larger the distance, the worse the aerosol separation effect, but the easier the suction. On the contrary, the smaller the distance, the better the aerosol separation effect, but the more difficult the suction. Generally, the distance is not less than 1 mm.

[0295] The outer edge of the baffle 810B can be basically completely attached to the inner wall of the separator housing 802B. Therefore, the flue gas basically does not flow through the gap between the baffle 810B and the separator housing 802B, and the flue gas can only flow in a zigzag shape along the ventilation holes 811B and the gap between the collision baffle groups.

[0296] The mixed flue gas formed after the liquid mist and the flue gas are mixed 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, due to the relatively large density of the moisture in the mixed flue gas, it cannot continue to flow after the collision baffle 810B, and is easily condensed into droplets and attached to the baffle 810B, and finally flows back to the mixing chamber 3 through the air inlet 806A. Due to the relatively small density of the flue gas, it can bypass the baffle 810B through the ventilation hole 811B after the collision baffle 810B and continue to flow in the direction of the second air inlet 807B. After entering the second air inlet 807B, it flows out from the air outlet 808B along the flue gas path 809B, and finally the filtered flue gas flows to the mouthpiece 7 and is inhaled by the consumer.

[0297] When the aerosol separation device 800B needs to be cleaned, only need to remove the aerosol separation device 800B from the liquid mist filtering smoking device, take out the separator cover body 801B and the collision separation structure 803B, and then clean them.

[0298] Figure 8-D and Figure 8-EAn embodiment of the aerosol separation device is shown. The aerosol separation device 800D includes a centrifugal separation structure. The aerosol separation device 800D mainly consists of three parts, namely a separator cover 801D, a separator housing 802D, and a centrifugal separation structure 803D. The aerosol separation device 800D can be hermetically installed at the smoke outlet 4 of the liquid mist filtering smoking device through the first sealing ring 804D on the separator cover 801D. The first sealing ring 804D can be an O-ring. The separator cover 801D and the separator housing 802D are hermetically fixed through the second sealing ring 805D to maintain the airtightness of the aerosol separation device 800D. The second sealing ring 805D can be an O-ring. In addition, sealing and fixing methods such as threads and flanges can also be used, which is convenient for disassembly or cleaning. The centrifugal separation structure 803D is connected below the separator cover 801D. The two can be integrally formed or connected by a detachable structure.

[0299] A first air inlet 806D is provided at the bottom of the separator housing 802D. The separator cover 801D has an axially penetrating smoke path 809D. The two ends of the smoke path 809D are respectively a second air inlet 807D and an air outlet 808D.

[0300] The centrifugal separation structure 803D has a spiral baffle 810D mounted on a support rod 811D. Figure 8-D In the embodiment, the spiral baffle 810D winds around the support rod 811D for a total of 3 turns. The pitch and the number of spiral turns of the spiral baffle 810D can be adjusted according to needs. The adjustment of the pitch and the number of spiral turns affects the final aerosol separation effect and the ease of suction. The larger the pitch, the worse the aerosol separation effect but the easier the suction. The more the number of spiral turns, the better the separation effect but the more difficult the suction. Generally, the pitch is not less than 1 mm.

[0301] The outer edge of the spiral baffle 810D can be basically completely fitted with the inner wall of the separator housing 802D. Therefore, the smoke basically will not flow through the gap between the spiral baffle 810D and the separator housing 802D. The smoke can only flow through the upward spiral air flow channel inside the spiral baffle 810D.

[0302] The mixed smoke formed after the liquid mist and the smoke are mixed in the mixing chamber 3 can enter the aerosol separation device 800D through the first air inlet 806D. During use, when the mixed smoke passes through the centrifugal separation structure 803B, due to the centrifugal force, the smoke and moisture will be separated. The liquid droplets will condense 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 air inlet 806A. The smoke can then flow through the spiral baffle 810D along the air flow channel and continue to flow in the direction of entering the second air inlet 807D. After entering the second air inlet 807D, it flows out from the air outlet 808D along the smoke path 809D and finally flows to the mouthpiece 7 and is inhaled by the consumer.

[0303] When the aerosol separation device 800D needs to be cleaned, simply remove the aerosol separation device 800D from the liquid mist filtering smoking device, take out the separator cover 801D and the centrifugal separation structure 803D, and then clean them.

[0304] Figure 8-F and Figure 8-G Fig. shows an embodiment of the aerosol separation device. The aerosol separation device 800F includes a centrifugal separation structure, which mainly consists of two parts, namely the separator cover 801F and the separator housing 802F. The aerosol separation device 800F can be hermetically installed at the smoke outlet 4 of the liquid mist filtering smoking device through the first sealing ring 804F on the separator cover 801F. The first sealing ring 804F can be an O-ring. The separator cover 801F and the separator housing 802F are hermetically fixed through the second sealing ring 805F to maintain the airtightness of the aerosol separation device 800F. The second sealing ring 805F can be an O-ring. In addition, sealing and fixing methods such as threads and flanges can also be used, so as to facilitate disassembly or cleaning.

[0305] The separator cover 801F and the separator housing 802F form a conical space inside. The conical space has a larger first end and a smaller second end. A first air inlet 806F is provided on the side wall of the first end along the tangential direction. The separator cover 801F is provided with a gas guiding column 811F along the axial direction on the end wall near the first end. The air inlet end of the gas guiding column 811F extends towards the bottom of the conical space to form a second air inlet 807F, and the air outlet end of the gas guiding column 811F extends towards the end wall of the first end to form an air outlet 808F. A smoke path 809F is formed in the middle of the gas guiding column 811F.

[0306] The mixed smoke formed after the liquid mist and the smoke are mixed in the mixing chamber 3 can enter the aerosol separation device 800F through the first air inlet 806F. Due to the fact that the smoke has a certain initial velocity, under the action of the outer edge of the gas guiding column 811F and the inner wall of the conical space of the separator housing 802F, it is roughly in a swirling flow state. At this time, the mixed smoke is affected by the centrifugal force, and part of the moisture condenses on the inner wall of the separator housing 802F. Since the second air inlet 807F is below and the opening faces downward, the flow state of the mixed smoke is rotating downward. Under the combined action with gravity, the condensed moisture will flow to the bottom of the separator housing 802F. When the mixed smoke enters the gas guiding column 811F from the bottom of the conical space, the direction of the air flow changes by about 180°. At this time, due to the relatively large density of the remaining moisture, most of the moisture is affected by inertia and will condense at the bottom of the conical space. After the smoke enters the second air inlet 807F, it flows out from the air outlet 808F along the smoke path 809F, and finally flows to the mouthpiece 7 and is inhaled by the consumer.

[0307] When the aerosol separation device 800F needs to be cleaned, simply remove the aerosol separation device 800F from the liquid aerosol filtering smoking device, take out the separator cover 801F, and then clean it.

[0308] In one embodiment, the aerosol separation device may include at least two different aerosol separation structures selected from a filtration separation structure, a collision separation structure, and a centrifugal separation structure. The two different aerosol separation structures may be in a parallel or series configuration. The two different aerosol separation structures may also be combined together. For example, baffles for collision separation may be provided in the air flow channel of the centrifugal separation structure.

[0309] Figure 9-A An embodiment of the waste liquid collection device is shown. The waste liquid collection device 900A includes an anti-backflow structure and a waste liquid chamber 904A. The anti-backflow structure is used to at least partially prevent the waste liquid from flowing back from the waste liquid chamber 904B to the mixing chamber 3. For example, at least ensure that the waste liquid cannot flow back to the mixing chamber 3 from the waste liquid chamber 904B in a large amount instantaneously. The waste liquid chamber 904A can provide sufficient capacity to accommodate the waste liquid. The anti-backflow structure includes a waste liquid channel 901A connecting the waste liquid chamber 904A and the mixing chamber 3. The passage area of the first opening 902A of the waste liquid channel 901A near the mixing chamber 3 is significantly larger than the passage area of the second opening 903A at the other end. Preferably, the passage area of the first opening 902A is at least twice the passage area of the second opening 903A. When the liquid aerosol filtering smoking device is placed vertically normally, the waste liquid in the mixing chamber 3 can easily flow into the waste liquid channel 901A through the larger-area first opening 902A and flow into the waste liquid chamber 904A from the second opening 903A. When the liquid aerosol filtering smoking device is tilted or even inverted due to shaking during carrying, the waste liquid in the waste liquid chamber 904A is difficult to flow into the waste liquid channel 901A through the smaller-area second opening 903A and flow back to the mixing chamber 3 from the first opening 902A.

[0310] Figure 9-B to Figure 9-E An embodiment of the waste liquid collection device is shown. The waste liquid collection device 900B is composed of a cover 908B and a housing 906B. The cover 908B is arranged above the housing 906B. The space inside the housing 906B below the cover 908B forms a waste liquid chamber 904B. The waste liquid collection device 900B is detachably installed on the liquid aerosol filtering smoking device for easy cleaning or replacement. Figure 9-E The state of the waste liquid collection device 900B installed on the main body of the liquid aerosol filtering smoking device is shown. The upper part of the outer side of the housing 906B has a threaded seal port 909B. A first sealing strip 910B is arranged above the cover 908B. When the waste liquid collection device 900B is screwed into the main body of the liquid aerosol filtering smoking device by threads and installed in place, the first sealing strip 910B on the cover 908B cooperates with the main body of the liquid aerosol filtering smoking device to form a seal.

[0311] The cover 908B can be hermetically connected to the housing 906B through a circumferentially arranged second sealing strip 912B to ensure tightness. The second sealing strip 912B can be arranged on the outer side of the cover 908B and / or the inner side of the housing 906B. Figure 9-D An embodiment is shown in which the second sealing strip 912B is arranged on the outer side of the cover 908B. The cover 908B can be rigid or flexible, and a more preferred embodiment is to make it of a soft material such as silica gel.

[0312] The connection mode between the waste liquid collection device 900B and the liquid mist filtering smoking device main body can be threaded or flange docking, etc., as long as it can form a sealed environment. To facilitate the removal of the waste liquid collection device 900B from the liquid mist filtering smoking device main body, a groove 911B can be arranged below the outer side of the housing 906B to increase the surface friction.

[0313] The waste liquid collection device 900B has an anti-backflow structure to at least ensure that the waste liquid cannot flow back to the mixing chamber 3 in a large amount instantaneously. The cover 908B includes a first opening 902B and a second opening 903B. The cover 908B forms a waste liquid channel, and the area of the first opening 902B of the waste liquid channel close to the mixing chamber 3 is larger than the area of the second opening 903B at the other end. A one-way valve structure can be arranged at the first opening 902B and / or the second opening 903B in the cover 908B.

[0314] The anti-backflow structure of the waste liquid collection device 900B can include a water absorption part 907B, and the water absorption part 907B can be arranged on the cover 908B and / or the waste liquid chamber 904B. Figure 9-B An embodiment is shown in which the water absorption part 907B is arranged on the cover 908B. A protrusion 913B and a groove 914B are arranged at the bottom of the cover 908B, and the groove 914B communicates with the second opening 903B of the cover 908B. When the water absorption part 907B is arranged on the cover 908B, the waste liquid can also quickly flow from the groove to the second opening 903B and enter the waste liquid chamber 904B. The water absorption part 907B can be taken out of the cover 908B smoothly for cleaning or replacement. At least a part of the water absorption part 907B is composed of sponge, porous body and / or water absorption resin. The volumes of the water absorption part 907B and the cover 908B can be defined by oneself. But generally only a smaller volume is needed to ensure that when the liquid mist filtering smoking device is tilted or even inverted temporarily due to carrying and shaking, the waste liquid will not flow back to the mixing chamber 3 quickly and cause pollution.

[0315] Figure 9-FAn embodiment of the waste liquid collection device is shown. In the waste liquid collection device 900F, the water absorption part 907F and the cover body 908F occupy all the internal space of the housing 906F, and the water absorption part 907F completely squeezes the space of the waste liquid chamber. Since the water absorption part 907F is completely used to store the waste liquid, violent shaking, long-term tilting or even inversion can ensure that the waste liquid will not quickly flow back to the mixing chamber 3 and cause pollution.

[0316] Figure 9-G An embodiment of the waste liquid collection device is shown. The waste liquid collection device 900G is provided with a valve 905G below the housing 906G. In the case of only needing to pour out the waste liquid, the valve 905G can be opened to allow the waste liquid to flow out from the waste liquid chamber 904G. The valve 905G can be connected to the housing 906G in the form of threads, flanges or silicone seals, etc.

[0317] Figure 9-H to Figure 9-J An embodiment of the waste liquid collection device is shown. The waste liquid collection device 900H is composed of a cover body 908H and a housing 906H. The cover body 908H is hermetically arranged above the housing 906H, and the space inside the housing 906H below the cover body 908H forms a waste liquid chamber 904H.

[0318] The waste liquid collection device 900H is detachably installed on the liquid mist filtering smoking device for easy cleaning or replacement. The upper part of the outer side of the housing 906H has a threaded seal port 909H, and a first sealing strip 910H is arranged above the cover body 908H. When the waste liquid collection device 900H is screwed into the liquid mist filtering smoking device main body by threads and installed in place, the first sealing strip 910H on the cover body 908H cooperates with the liquid mist filtering smoking device main body to form a sealed environment. The cover body 908H can be made of a soft material such as silicone to form the first sealing strip 910H, or can also be connected to the liquid mist filtering smoking device main body by sealing methods such as flanges and pressure. The cover body 908H can also be made of a rigid material, and a sealing O-ring, etc. is added thereto to form the first sealing strip 910H to ensure the sealing performance.

[0319] The waste liquid collection device 900H has an anti-backflow structure, which at least ensures that a large amount of waste liquid cannot flow back from the waste liquid chamber 904H to the mixing chamber 3 instantaneously. The cover body 908H includes a first opening 902H and a second opening 903H, and the cover body 908B forms a waste liquid channel 901H. The apertures of the waste liquid channel 901H, the first opening 902H, and the second opening 903H are relatively small, preferably with a radius of less than 3 mm. The main function of the waste liquid channel 901H is to allow the waste liquid to flow into the waste liquid chamber 904H. At the same time, when the appliance is used in different states, it restricts the backflow of the waste liquid into the mixing chamber 3. The waste liquid channel 901H can be made of rigid or flexible materials. The waste liquid channel 901H can be integrated with the cover body 908H into one part or fixed to the cover body 908H through mechanical connection structures, etc. The second opening 903H of the waste liquid channel 901H should be below half of the height of the waste liquid chamber 904H (in the downward orientation of the normal use state of the waste liquid chamber 904H, such as Figure 9-H and 9-I shown), and a more preferred position is below one-third of the height of the waste liquid chamber 904H. At this time, more waste liquid backflow can be restricted.

[0320] Figure 9-I Figure Figure 9-I shows the usage state diagram of the waste liquid collection device 900H when the aerosol filtering smoking device is placed vertically normally. The waste liquid in the mixing chamber 3 can flow into the waste liquid channel 901H through the first opening 902H under the action of gravity and enter the interior of the waste liquid chamber 904H from the second opening 903H.

[0321] Figure 9-J Figure Figure 9-J shows the usage state diagram of the waste liquid collection device 900H when the aerosol filtering smoking device is inverted abnormally. Due to the action of gravity, the waste liquid will not always stay at the bottom as the waste liquid chamber 904H is inverted. At this time, since the second opening 903H of the waste liquid channel 901H is above the liquid level of the waste liquid, the waste liquid cannot flow out of the waste liquid chamber 904H.

[0322] Figure 9-K Figure Figure 9-K shows an implementation manner of the waste liquid collection device. The waste liquid collection device 900K is a variant of the waste liquid collection device 900H, and the waste liquid channel 901K can be bent, thus having a labyrinth structure. When the aerosol filtering smoking device is placed vertically normally, the waste liquid in the mixing chamber 3 can flow into the interior of the waste liquid collection device 900K under the action of gravity; when the aerosol filtering smoking device is tilted or even inverted due to being carried and shaken, due to the labyrinth structure of the waste liquid channel 901K and the complex pipeline, the probability of the waste liquid flowing out is greatly reduced. Even if a small amount of waste liquid flows back into 901K, it is very difficult to flow through the entire waste liquid channel 901K and then flow back to the mixing chamber 3 to cause pollution.

[0323] Figure 10Shown is an embodiment of a mouthpiece, the mouthpiece 1000. The mouthpiece mainly consists of 4 parts, namely the connecting seat 1001, the ventilation pipe 1002, the deflection and positioning pipe 1003, and the mouthpiece head 1004.

[0324] Among them, the deflection and positioning pipe sleeve 1003 is connected to the outside of the ventilation pipe 1002. One end of the ventilation pipe 1002 is connected to the mouthpiece head 1004, and the other end of the ventilation pipe 1002 is connected to the connecting seat 1001. In another embodiment, the deflection and positioning pipe 1003 and the ventilation pipe 1002 can be combined into one part by injection molding or welding. The function of the deflection and positioning pipe 1003 is to limit the deformation of the ventilation pipe 1002 to ensure that the ventilation pipe 1002 can be bent and arbitrarily deflected and positioned. The deflection and positioning pipe 1003 can adopt the form of a corrugated pipe, a gooseneck pipe, a deformed metal hose, etc. In another embodiment, the deflection and positioning pipe 1003 is wound into a spiral spring shape by a metal wire with good plasticity (such as aluminum, silver, copper, etc.). The diameter of the metal wire can be 0.1 - 3mm, and the relatively preferred diameter of the metal wire is 1 - 2mm. Selecting the above-mentioned form of the deformed positioning pipe requires relatively less force when bending, which is more suitable for one-handed adjustment in the use state of the smoking device, and can be specifically determined according to the required feel.

[0325] The function of the connecting seat 1001 is to connect the mouthpiece 1000 to the housing of various smoking devices, and its connection with the housing of the smoking device can be a connection method that can ensure airtightness, such as screw connection, socket connection, flange, etc.

[0326] The function of the ventilation pipe 1002 is to allow the smoke to pass through, and it needs to meet the food safety requirements. It can adopt the form of a silicone tube, a latex tube, a plastic corrugated pipe, a bendable straw, etc.

[0327] The function of the mouthpiece head 1004 is to contact the consumer's oral cavity and needs to meet the food safety requirements. In another embodiment, the mouthpiece head 1004 can be combined with the ventilation pipe into an integral body. In another embodiment, the connecting seat 1001, the ventilation pipe 1002, or the mouthpiece head 1004 is detachable. The advantage of being detachable and separable is that it is convenient for replacement and cleaning, because after long-term use of the smoking device, there will be more pollutants remaining in the ventilation pipe.

[0328] This mouthpiece 1000 not only meets the suction requirements for using the smoking device in different states but also does not affect the portability of the smoking device.
