Description

Technical Field

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

[0002] In recent years, as people pay more and more attention to health, they have realized that traditional cigarettes have certain harm to health. The impact of traditional cigarettes on health and the environment has gradually begun to receive attention from countries around the world.

[0003] It has become a consensus at home and abroad that smoking is harmful to health. Since tar and other harmful components 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 reducing harm. At present, there are various types of hookah smoking utensils on the market, which 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 allows many harmful components in the smoke to be filtered by liquid to reduce harm to the human body.

[0004] However, in this type of smoking device, the smoke is in the form of bubbles when passing through water. 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 contact 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 smoke to filter smoke came into being. The main mixing and filtering process of the liquid mist filtering smoking device is that the smoke airflow and the atomized liquid mist flow contact and mix with each other, and then filter and absorb some components in the original smoke before being inhaled by consumers.

[0006] The liquid mist filtering smoking device inserts the cigarette into a specific position, and the released smoke is filtered through water, reducing some of the harm of cigarettes to the human body; however, since the cigarette is fixed on a large device, it is inconvenient to shake off the ash, which can easily cause the ash to scatter and affect the surrounding environment.

[0007] Therefore, there is a need for an elastic cigarette holder so that cigarette ash can be shaken off more conveniently when using the above-mentioned smoke filtering device. Summary of the invention

[0008] The purpose of the present invention is to provide a novel elastic cigarette holder so as to facilitate users to quickly and conveniently shake off cigarette ashes when using cigarettes.

[0009] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0010] An elastic cigarette holder installed on a smoking device, comprising: a cigarette bin, located at the front end of the elastic cigarette holder, for inserting cigarettes, the inner diameter of the cigarette bin being slightly smaller than the diameter of the cigarette; a base, located at the rear end of the elastic cigarette holder, for connecting to the smoking device; an elastic flue, which is a hollow pipe made of elastic material, for connecting the cigarette bin and the base; the cigarette bin, the base and the elastic flue together form an internal through passage from the cigarette to the smoking device.

[0011] Furthermore, the hardness of the elastic material is between 40 and 70 degrees.

[0012] Furthermore, one or more paddles are protruding from the outer side of the cigarette bin, so that the user can pry the cigarette bin, causing the cigarette bin to quickly displace relative to the base due to the elastic effect of the elastic flue, thereby shaking off the ashes of the cigarette.

[0013] Furthermore, the cigarette bin is made of soft material, and a sealing ring is provided at the front end of the cigarette bin to prevent smoke from leaking out from the front end of the elastic cigarette holder.

[0014] Furthermore, the sealing ring is made of hard material.

[0015] Furthermore, the inner diameter of the cigarette bin is larger than the inner diameters of the base and the elastic smoke duct, and a circular hollow positioning platform is formed at the bottom of the cigarette bin due to the inner diameter difference, which is used to prevent cigarettes from entering the elastic smoke duct.

[0016] Furthermore, a fixing buckle is provided on the base for cooperating with the smoking device to fix the elastic cigarette holder.

[0017] Furthermore, the base is provided with an axial positioning device in front of the fixing buckle, and its outer diameter is larger than the inner diameter of the mounting hole on the smoking device, so as to limit the installation depth of the elastic cigarette holder.

[0018] Furthermore, the circumferential positioning is provided on the axial positioning to limit the installation direction of the elastic cigarette holder, thereby ensuring that the angle of the pick is suitable for user use.

[0019] Furthermore, the base is made of the elastic material, and the base is interference fit with the mounting hole of the smoking device.

[0020] When the present invention is in use, a cigarette is inserted into the cigarette bin for normal inhalation. When the ash needs to be shaken off, the finger of the hand holding the device is directly used to move the paddle, so that the cigarette bin produces a certain rapid displacement to shake off the ash. After the hand is released, the cigarette bin returns to its original position due to the elastic effect. Using this ash shaking-off device, it is very convenient to operate with one hand like shaking off the ash normally, so as to avoid the ash being scattered everywhere and polluting the surrounding environment.

[0164] The detailed features and advantages of this patent are described in detail in the specific implementation method below, and the content is sufficient to enable any technical personnel in this field to understand the technical content of this patent and implement it accordingly. According to the description, claims and drawings disclosed in this specification, technical personnel in this field can easily understand the relevant purposes and advantages of this patent.

[0165] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0166] In the description of this embodiment, it should be noted that the orientation or position relationship indicated by the terms "upper", "lower", "inner", "bottom", etc. is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product is usually placed when used. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of this patent.

[0167] In order to make the purpose, technical solutions and advantages of this patent clearer, the implementation method of this patent will be further described in detail below in conjunction with the accompanying drawings.

[0168] like Figure 1-A As 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 suction nozzle 7, an aerosol separation device 8 and a waste liquid collection device 9.

[0169] The smoke inlet 1 is connected to the mixing chamber 3, and one end of the filter of a conventional cigarette (not shown in the figure) can be inserted at the smoke inlet 1. After the conventional cigarette is ignited, the smoke can enter the mixing chamber 3 from the smoke inlet 1. In another embodiment, the smoke at the smoke inlet 1 can be generated by tobacco shreds, tobacco leaves, tobacco flakes, and other combustible materials containing nicotine or nicotine salts. The liquid mist generating device 2 is connected to the mixing chamber 3, and 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 smoke outlet 4 is connected to the mixing chamber 3, and after the liquid mist and the smoke are mixed in the mixing chamber 3, the mixed smoke flows out from the smoke outlet 4. The control system 6 can be used to control the switch of the liquid mist generating device 2, the amount of mist output, etc. The smoke outlet 4 has a suction nozzle 7, and the consumer can inhale the filtered smoke through the suction nozzle 7. The smoke outlet 4 has an aerosol separation device 8. Since the mixed smoke directly flowing out of the smoke outlet 4 after the liquid mist and smoke are mixed in the mixing chamber 3 will contain more liquid mist components, the aerosol separation device 8 can be provided to further separate the liquid mist components in the mixed smoke. After the liquid mist and smoke are mixed in the mixing chamber 3 and separated by the aerosol separation device 8, a considerable portion 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 provided below the smoke mixing chamber 3, which is connected to the bottom of the smoke mixing chamber 3 and is used to collect the waste liquid in the smoke mixing chamber 3.

[0170] like Figure 1-B and Figure 1-C As shown, in one embodiment, the liquid mist filtering smoking device includes a liquid mist contact module A and a liquid mist isolation module B. The figure further illustrates the flow paths and directions of smoke and liquid mist between the modules through modules and arrows.

[0171] Arrow ①: The original smoke generated by the combustion of traditional cigarettes enters the mixing chamber 3 from the smoke inlet 1.

[0172] Arrow ②: waste liquid enters the waste liquid collecting device 9 from the flue gas mixing chamber 3.

[0173] Arrow ③: after the liquid mist and the smoke are mixed in the mixing chamber 3 , the mixed smoke enters the mist separation device 8 at the smoke outlet 4 ; a considerable portion of the liquid mist condenses into water droplets in the mist separation device 8 and flows back to the mixing chamber 3 .

[0174] Arrow ④: Filtered smoke enters the suction nozzle 7 at the smoke outlet 4 and is sucked out.

[0175] Arrow ⑤: The liquid mist generating device 2 atomizes the atomizing liquid into liquid mist and sprays it into the smoke mixing chamber 3.

[0176] Arrow ⑥: The atomized liquid enters the liquid mist generating device 2 from the liquid storage chamber 5.

[0177] Since the liquid mist filtering smoking device involved in this patent involves smoke passages, liquid passages and circuits, in order to ensure normal and safe use, it is necessary to arrange the various modules of this type of device reasonably. On the one hand, it is necessary to ensure the overall airtightness, and on the other hand, it is necessary to avoid the smoke and liquid from contacting the 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.

[0178] The liquid mist contact module A includes a smoke inlet 1, a mixing chamber 3, a smoke outlet 4 and a waste liquid collection device 9. The smoke inlet 1 can be interference-fitted with a conventional cigarette. The components of the liquid mist contact module are sealed by a silicone ring, a flange seal or a sealant to ensure airtightness. The components through which the liquid mist flows form a relatively closed whole, which effectively reduces the risk of liquid mist leakage.

[0179] The liquid mist isolation module B includes a liquid mist generating device 2 and a control system 6 .

[0180] There is only one connection port (arrow ⑤) between the liquid mist contact module and the liquid mist isolation module, and the liquid mist generating device 2 and the mixing chamber 3 are allowed to be connected to each other through the connection port. The liquid mist generating device is arranged at the connection port in a sealing manner, and the sealing manner includes 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 by the liquid storage chamber can enter the mixing chamber 3 in the liquid mist contact module A from the one-way channel in the form of liquid mist. The module for contacting the liquid mist is basically independent of the module for isolating the liquid mist, and there is only one necessary connection port, which effectively protects the control system and prolongs the service life of the control system.

[0181] The liquid mist isolation module B may further include a control cabin for accommodating the control system 6, and the control cabin 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 does not flow into the control cabin, thereby damaging the control system 6. The control cabin is provided with an electrical connection through hole, and the control system 6 and the liquid mist generating device 2 are connected to each other through the electrical connection through hole, and the electrical connection through hole is sealed, including using a sealing ring or silicone filling.

[0182] The above sealing and connecting method is very simple and easy to reuse, replace and expand components.

[0183] Preferably, a flange seal is used between the mixing chamber 3 and the waste liquid collecting device 9 (arrow ②).

[0184] Preferably, flange sealing is adopted for the installation connection between the aerosol separation device 8 (arrow ③) and the suction nozzle 7 (arrow ④).

[0185] Preferably, the smoke inlet 1 is provided with a cigarette holder, and the cigarette holder and the mixing chamber 3 are sealed with silicone.

[0186] Preferably, the liquid mist generating device is sealed with the connecting port by means of silicone.

[0187] 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 smoke inlet 1 and the smoke 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 Figure 1-A , 1-B and 1-C clearly show.

[0188] Figure 5-A The main module of the liquid mist generating device is shown. The main module includes a mixing chamber 3, a liquid mist generating device 2 and a control system 6. The main module provides the key functions of the liquid mist generating device: atomization filtration and control. The shell of the main module can be integrated.

[0189] Figure 5-B The smoke channel module of the liquid mist generating device is shown, and the smoke channel module includes a smoke inlet 1, a smoke outlet 4, a suction nozzle 7 and an aerosol separation device 8. The smoke before and after filtration enters and exits the main module through the smoke channel module.

[0190] Figure 5-C The water storage module of the liquid mist generating device is shown, and the water storage module includes a liquid storage chamber 5 and a water storage cover. The water storage cover can be an internal thread screw cap or a plug cap made of a soft material (such as rubber).

[0191] like Figure 5-D As shown, the wastewater collection module includes a waste liquid collection device 9 and a detachable valve (optional) at the bottom thereof.

[0192] When smoke enters the mixing chamber and intersects with the liquid mist, an angle is formed. The angle can be changed by adding corresponding mechanical structures at the smoke inlet and / or the liquid mist generating device. When the angle change is guided by the mechanical structure, the atomization effect will also change accordingly.

[0193] like Figure 2-A As shown, in one embodiment of the liquid mist filtering smoking device, the liquid mist filtering smoking device is a liquid mist filtering smoking device with an adjustable aerosol mixing angle, including a mixing chamber 201, a cigarette clamping component 202, a liquid mist generating device 203, a mixed smoke outlet 204, a condensed waste liquid outlet 205 and a smoke inlet 206.

[0194] The mixed smoke outlet 204 is connected to the mixing chamber 201, so that the smoke and liquid mist can flow out after being mixed and filtered in the mixing chamber 201. The condensed waste liquid outlet 205 is connected to the mixing chamber 201, so that the waste liquid generated by condensation after the smoke and liquid mist are mixed and filtered can flow out.

[0195] The smoke entry direction of the smoke into the mixing chamber 201 and the liquid mist entry direction of the liquid mist into the mixing chamber 201 form an angle β, and the angle β can be changed.

[0196] The smoke entry direction of the smoke into the mixing chamber 201 and the liquid mist entry direction of the liquid mist into the mixing chamber 201 form an angle β, and the angle β can be changed.

[0197] The smoke inlet direction and the liquid mist inlet direction can be in the same plane (such as Figure 2-A and Figure 2-B As shown), it can also be in different planes (not shown, for example, in two planes that are parallel or non-parallel to each other).

[0198] Preferably, the smoke inlet direction and the liquid mist inlet direction are substantially in the same plane, in which case the angle β is preferably between 0° and 180°, more preferably 90±10°. If the smoke inlet direction and the liquid mist inlet direction are in different planes, a spatial angle β will be formed between them, similarly, the angle β is preferably between 0° and 180°, more preferably 90±10°.

[0199] The smoke inlet 206 is in communication with the mixing chamber 201, and smoke enters the mixing chamber 201 from the smoke inlet 206. The smoke entry direction of the smoke into the mixing chamber 201 can be changed. The smoke inlet 206 is provided on the cigarette clamping component 202, and the cigarette clamping component 202 is adjustably mounted on the mixing chamber 201. The smoke entry direction changes as the cigarette clamping component 202 is adjusted.

[0200] Preferably, a mounting groove is provided between the cigarette clamping component 202 and the cavity wall of the mixing chamber 201, so that it can slide on the cavity wall of the mixing chamber 201 to change the angle of the smoke entry direction.

[0201] Preferably, the cigarette clamping component 202 is adjusted by a mechanical lever or a motor drive.

[0202] Preferably, the smoke inlet portion is made of soft material, such as a silicone tube, a latex tube or a gooseneck tube, and the smoke entry direction is changed by bending the soft material.

[0203] The liquid mist generating device 203 is connected to the mixing chamber 201. After the liquid mist and smoke generated by the liquid mist generating device 203 are mixed in the mixing chamber 201, the filtered smoke flows out from the mixed smoke outlet 204. The liquid mist generating device 203 is adjustably mounted on the mixing chamber 201, and the liquid mist entry direction changes with the adjustment of the liquid mist generating device 203.

[0204] 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.

[0205] Preferably, the liquid mist generating device 203 is adjusted by a mechanical lever or a motor drive.

[0206] 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.

[0207] Arrow a: direction of smoke entering the mixing chamber 201 .

[0208] Arrow b: direction in which the liquid mist enters the mixing chamber 201 .

[0209] Arrow c: the outflow direction of the mixed flue gas leaving the mixing chamber 201 .

[0210] Arrow d: direction in which waste liquid flows out of the mixing chamber 201 .

[0211] Arrow e: variable direction of the smoke channel.

[0212] Arrow f: variable direction of the liquid mist spray.

[0213] 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.

[0214] 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:

[0215] 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 inlet direction of the flue gas and the inlet direction of the liquid mist).

[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-A In one implementation 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 mixed smoke angle through the user interface, and the 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 angle β input by the user to obtain the driving data of the motor. The motor is linked with the gear structure to drive the liquid mist generating device to rotate, thereby adjusting the angle β between the smoke entry direction and the liquid mist entry direction.

[0221] In the above process, the main control chip detects the encoder / position sensor feedback reading in real time until the liquid mist generating device rotates to the mixed smoke angle position required by the user, and then the main control chip stops and locks the motor.

[0222] In one embodiment of the liquid mist filtering smoking article, the liquid mist filtering smoking article comprises a smoke inlet, a liquid mist generating device, a mixing chamber, a smoke outlet and a control system.

[0223] The smoke inlet is connected to the mixing chamber, and the smoke enters the mixing chamber from the smoke inlet; the smoke outlet is connected to the mixing chamber; the liquid mist generating device is connected to the mixing chamber; the liquid mist generated by the liquid mist generating device and the smoke are mixed in the mixing chamber, and then flow out from the smoke outlet to filter the smoke.

[0224] The control system is used to receive instructions from the user end and control the liquid mist filtering smoking device to operate normally according to the instructions. The control system includes a DC voltage stabilizing circuit, a filtering circuit, a main control chip, a DC-AC conversion resonant circuit and a feedback sampling circuit.

[0225] The DC voltage regulator circuit is designed for low-voltage energy storage element power supply applications. For example, when a single battery is used for power supply, and the control end operating voltage of the DC-AC conversion resonant circuit is 5V, the DC voltage regulator circuit will increase the voltage to 5V (the main control chip controls whether the DC voltage regulator circuit starts working). The purpose of setting the voltage regulator circuit is to produce stable mist. If the voltage regulator circuit is not set, the atomization effect can also be achieved, but the atomization amount or atomization spray intensity during atomization will change with the voltage change.

[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] like Figure 3-A As 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 also includes a voltage regulating circuit.

[0228] The output of the DC voltage regulator circuit is connected to the voltage adjustment circuit. The main control chip adjusts the output voltage of the voltage adjustment circuit according to needs or user settings. The output voltage of the voltage adjustment circuit is filtered by the filter circuit and sent to the DC-AC conversion resonant circuit. The main control chip outputs a PWM signal to modulate the DC-AC conversion resonant circuit, and combined with the feedback signal of the feedback sampling circuit, the DC-AC conversion resonant circuit outputs a stable AC signal. The output AC signal drives the atomizer in the liquid mist generating device to atomize the atomized liquid to form a filtered liquid mist.

[0229] like Figure 3-B As shown, 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 also includes a current sampling circuit.

[0230] The output of the DC voltage regulator 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 voltage regulator circuit or the DC-AC conversion resonant circuit to adjust the current. The output voltage of the current sampling circuit is filtered by the filter circuit and sent to the DC-AC conversion resonant circuit. The main control chip outputs a PWM signal to modulate the DC-AC conversion resonant circuit, and combined with the feedback signal of the feedback sampling circuit, the DC-AC conversion resonant circuit outputs a stable AC signal. The output AC signal drives the atomizer in the liquid mist generating device to atomize the atomized liquid to form a filtered liquid mist.

[0231] like Figure 3-C As shown, when the control system changes the duty cycle of the liquid mist generating device to control the mist output of the liquid mist generating device, the output of the DC voltage stabilizing circuit is connected to the filter circuit for filtering to make the voltage more stable. The control system also includes a resonant drive chip.

[0232] The stabilized power supply, filter circuit, DC-AC conversion resonant circuit, atomizer, resonant drive chip, and feedback sampling circuit work together to complete the atomization function (hereinafter referred to as the atomization module). The atomization module has two inputs: the power signal input by the filter circuit and the atomization module control signal output by the main control chip. When the atomization module is working, the DC voltage is first converted into an AC signal through the DC-AC conversion resonant circuit in conjunction with the modulation signal of the resonant drive chip. The resonant drive chip adjusts the resonant drive signal in combination with the DC-AC conversion resonant circuit information 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 atomizer in the liquid mist generating device to atomize the atomized liquid to form a filtered liquid mist.

[0233] When the liquid mist power needs to be adjusted, the main control chip modifies the output duty cycle signal, controls the DC voltage stabilization circuit or the atomization module to work intermittently, and adjusts the average power value per unit time.

[0234] In one embodiment of the liquid mist filtering smoking device, the liquid mist filtering smoking device comprises a smoke inlet, a liquid mist generating device, a mixing chamber, a smoke outlet and a control system. The smoke inlet is connected to the mixing chamber, and smoke enters the mixing chamber from the smoke inlet; the smoke outlet is connected to the mixing chamber; the liquid mist generating device is connected to the mixing chamber; the liquid mist generated by the liquid mist generating device and the smoke are mixed in the mixing chamber, and then flow out of the smoke outlet to filter the smoke; the control system is used to control the mist output form of the liquid mist generating device.

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

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

[0237] Circuit input: including liquid mist components, filtration methods and flue gas related signals, etc.

[0238] The filtering method refers to the need to perform a gas-liquid separation process on the mixed gas at the front end of the nozzle after the smoke and liquid mist are mixed. This parameter can be determined by user input, or by attaching an identification chip 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 generating agent, and consumers can independently select the appropriate matrix to be atomized with different added flavors, etc.

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

[0241] The particle size and power of the liquid mist can be controlled by the electrical parameters of the atomizing element. Currently, there are three main atomization methods, namely ultrasonic, jet and pressure atomization. The circuit system adjusts the voltage, frequency and duty cycle according to the input; the direction of the liquid mist spray can be converted into an electrical signal by the position sensor. The liquid mist components are selected by consumers to be atomized with different added flavors.

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

[0243] like Figure 4-BAs shown, the physical quantities covered by the smoke signal input by the circuit include: the type of cigarette, the capacity of a single puff, the flow rate of smoke and the direction of smoke 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 cigarettes (such as leaf shreds, stem shreds, thin slices, etc.). The above parameters can be pre-input into the control system of the smoking device by the user, or the device can automatically identify the cigarette information (such as cigarette LOGO, barcode, QR code, etc.); the capacity of a single puff and the flow rate of smoke can be received by the flow sensor attached to the smoking device when the consumer takes a puff and converted into electrical signals for input; the airflow direction can be converted into electrical signals by position sensors, etc.

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

[0245] like Figure 4-C The figure 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.

[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 to perform the corresponding atomization form according to the control signal and feeds back 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 user's input information and transmit the information to the main control chip. The input information includes one or more of a power on / off signal, a gear position, a tobacco type, a liquid mist generating agent type, a smoke moisture content, a smoke temperature, 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 light, a motor, a voice module, and a buzzer, and is used to provide feedback of the system status to the user. The output information includes one or more of working status, gear position, power, charging indication, low-power prompt, tobacco type, liquid mist generating agent type, smoke moisture content, smoke temperature, nicotine content, airflow, airflow velocity, and air pressure.

[0249] The atomization circuit module includes a voltage-stabilized power supply, a filter circuit, a DC-AC resonant circuit, a resonant 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 to achieve atomization of the target substance.

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

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

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

[0253] Step ② The input module obtains input information of the cigarette in the lit 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 operation is completed.

[0258] The control system can calculate the electrical signal to be controlled by system table lookup or empirical function. When the control system uses the system table lookup method, the main control chip stores a corresponding table of input information and control signals.

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

[0260] After starting the liquid mist filter smoking device, the input module obtains the liquid mist generating agent type and the cigarette type, takes the liquid mist generating agent as the X-axis and the cigarette type as the Y-axis, and finds the initial atomization electric power through the two-dimensional table lookup method, as shown in Table 2:

[0261] Table 2

[0262] When the user uses a type n cigarette and selects liquid mist generating agent 3, the control system selects P3n as the initial atomization power by looking up the table.

[0263] The system starts atomization, and the system monitors the smoke moisture parameters, smoke temperature, and smoke volume parameters in real time. Then, the system also uses a table lookup (here, the cigarette type VS liquid mist generating agent table) to obtain the corrected electric power value. The main control chip outputs the adjusted atomization electric power to the atomization control module. This process is repeated until the smoke parameters with the best taste in the setting are obtained, or until this operation is completed.

[0264] The final output key parameters are combined with the expected filtered smoke, which improves the consumer experience and meets the personalized needs of consumers.

[0265] In one embodiment of the 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.

[0266] The smoke inlet is connected to the mixing chamber, and the smoke enters the mixing chamber from the smoke inlet; the smoke outlet is connected to the mixing chamber; the liquid mist generating device is connected to the mixing chamber; the liquid mist generated by the liquid mist generating device and the smoke are mixed in the mixing chamber, and the mixed smoke flows out from the smoke outlet.

[0267] 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.

[0268] The atomization circuit module may include a filter circuit, a DC-AC resonant circuit and a resonant drive chip. The atomization circuit module is connected to the atomization sheet in the liquid mist generating device to control its operation.

[0269] The liquid level detection circuit may include a liquid level sensor. The liquid level sensor is one or more of a liquid level probe sensor, a laser sensor, a microwave sensor, an ultrasonic sensor, a photoelectric sensor, a pressure sensor or a capacitive sensor. When the liquid level sensor is a liquid level probe sensor, the position of the liquid level sensor is as close to the atomizer as possible.

[0270] The main control chip monitors the feedback signal sent by the liquid level sensor in real time and compares the feedback signal with the preset liquid shortage threshold. When it is determined that the atomization liquid amount is insufficient, the main control chip shuts down the atomization block through a control signal.

[0271] The liquid mist filtering smoking device may further include an output module, which is connected to the main control chip and is used to feed back abnormal operation conditions of the liquid mist filtering smoking device to the user.

[0272] Figure 6 A preferred embodiment of a liquid mist filtering smoking device is shown, wherein the atomization circuit module thereof further includes a feedback sampling circuit, and the operation monitoring system thereof further includes a power sampling circuit.

[0273] 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 integral value with the preset liquid shortage threshold. When the integral value is lower than the liquid shortage threshold, the main control chip reduces the atomization power of the atomization circuit module through a control signal.

[0274] The power sampling circuit is connected to the main control chip, and the power sampling circuit is used to monitor the power voltage input to the atomization circuit module in real time. When the power voltage received by the main control chip is lower than the preset under-power threshold, the main control chip shuts down the atomization circuit module through a control signal.

[0275] 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.

[0276] 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.

[0277] The elastic cigarette holder 700 comprises 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.

[0278] 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.

[0279] 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.

[0280] 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.

[0281] 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.

[0282] The elastic flue 703 is a hollow pipe made of elastic material, which is used to connect the cigarette bin 701 and the base 702. The elastic flue has a certain degree of bendability, so that when the user moves the cigarette bin, the cigarette bin can be displaced relative to the base. The hardness of the elastic material is between 40 and 70 degrees. The elastic material can be one or more of silicone or rubber. The length of the elastic flue can be adjusted according to the hardness to ensure that the cigarette bin can rebound quickly after the paddle is moved.

[0283] like Figure 7-BAs shown, the inner diameter of the cigarette 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 bottom of the cigarette bin due to the inner diameter difference to prevent cigarettes from entering the elastic flue and ensure that the cigarettes will not affect the deformation of the elastic flue.

[0284] When in use, the cigarette is inserted into the cigarette bin and smoked normally. When the ash needs to be shaken off, the pick is directly moved with the fingers of the hand holding the device to cause the cigarette bin to produce a certain rapid displacement to shake off the ash. After releasing the hand, the cigarette bin returns to its original position due to the elastic effect. Using this ash shaking-off device, it is very convenient to operate with one hand like shaking off the ash normally, avoiding the ash from scattering everywhere and polluting the surrounding environment.

[0285] The smoke outlet is provided with an aerosol separation device 8. Since the mixed smoke directly flowing out of the smoke outlet 4 after the liquid mist and smoke are mixed in the mixing chamber 3 will contain more liquid mist components, an aerosol separation device 8 can be provided to further separate and filter the liquid mist components in the smoke.

[0286] Figure 8-A An embodiment of an aerosol separation device is shown, and the aerosol separation device 800A includes a filter separation structure. The aerosol separation device 800A is mainly composed of three parts, namely, a separator cover 801A, a separator housing 802A and a filter separation structure 803A. The aerosol separation device 800A can be airtightly installed on the smoke outlet 4 of the liquid mist filtering cigarette device through the first sealing ring 804A on the separator cover 801A, and the first sealing ring 804A can 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 airtightness of the aerosol separation device 800A. The second sealing ring 805A can be an O-ring. In addition, sealing fixing methods such as threads and flanges can also be used to facilitate disassembly or cleaning. The separator cover 801A and the separator housing 802A cooperate with each other to support and fix the filter separation structure 803A.

[0287] A first air inlet 806A is provided at the bottom of the separator shell 802A, and the separator cover 801A has an axially through-going smoke path 809A, with a second air inlet 807A and an air outlet 808A at the two ends of the smoke path 809A respectively. The mixed smoke formed by the mixing of 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 separation structure 803A, a part of the moisture will be filtered by the filtering and separation structure 803A, and part of the liquid mist condenses into water droplets and can flow back to the mixing chamber 3 through the air inlet 806A. After the smoke passes through the filtering and separation structure 803A, it enters the second air inlet 807A and flows out from the air outlet 808A along the smoke path 809A, and finally flows to the suction nozzle 7 and is inhaled by the consumer.

[0288] The filtering and separation structure 803A uses filtering and absorbing materials, which can be porous breathable materials, such as sponge, porous ceramics, metal mesh, non-metallic mesh, waterproof breathable membrane, etc. The pore size parameters of the material can be selected as needed.

[0289] When the aerosol separator 800A needs to be cleaned, it is only necessary to remove the aerosol separator 800A from the liquid mist filtering smoking device, separate the separator cover 801A and the separator shell 802A, and clean both of them. The absorption filter material 803A can also be taken out and replaced or cleaned.

[0290] Figure 8-B and Figure 8-C An embodiment of an aerosol separation device is shown, and the aerosol separation device 800B includes a collision separation structure. The aerosol 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 aerosol separation device 800B can be airtightly installed on the smoke outlet 4 of the liquid mist filtering smoking device through the first sealing ring 804B on the separator cover 801B, and the first sealing ring 804B can 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 airtightness of the aerosol separation device 800B. The second sealing ring 805B can be an O-ring. In addition, sealing fixing methods such as threads and flanges can also be used to facilitate disassembly or cleaning. The collision separation structure 803B is connected to the bottom of the separator cover 801B, and the two can be integrally formed or connected by a detachable structure.

[0291] A first air inlet 806B is provided at the bottom of the separator housing 802B, and the separator cover 801B has an axially penetrating smoke path 809B, with a second air inlet 807B and an air outlet 808B at both ends of the smoke path 809B.

[0292] The collision separation structure 803B has a plurality of collision baffles evenly distributed along the axial direction and arranged on a support rod. Figure 8-C The embodiment in the embodiment is 4 layers, and each layer of collision baffle group has a plurality of baffles 810B evenly distributed in the circumferential direction. Figure 8-CThere are three implementation methods in the embodiment, and vents 811B are formed between baffles 810B. The baffles on two adjacent layers of collision baffle groups are staggered, that is, from the axial direction, the vents of a certain layer of collision baffle group are facing the baffles of the next layer of collision baffle group. The position and shape of the baffles and vents in each layer of collision baffle group and the number of collision baffle groups can be designed differently. After multiple collision separations of the baffles, the moisture in the flue gas can be controlled to a more appropriate value. The more collision baffle groups there are, the larger the baffle shielding area, and the better the aerosol separation effect. The spacing between the collision baffle groups can be adjusted according to actual needs. The adjustment of the spacing affects the final aerosol separation effect and the difficulty of suction. The larger the spacing, the worse the aerosol separation effect, but the easier it is to suction. Conversely, the smaller the spacing, the better the aerosol separation effect, but the more difficult it is to suction. Generally, the spacing is not less than 1 mm.

[0293] The outer edge of the baffle 810B can fit almost completely with the inner wall of the separator shell 802B, so the smoke basically does not flow through the gap between the baffle 810B and the separator shell 802B, and the smoke can only flow in a zigzag manner along the gap between the vent 811B and the collision baffle group.

[0294] The mixed smoke formed after the liquid mist and smoke are mixed in the mixing chamber 3 can enter the mist separation device 800B through the first air inlet 806B. When the mixed smoke passes through the collision separation structure 803B, the water in the mixed smoke cannot continue to flow after colliding with the baffle 810B due to its high density, and it is easy to condense into droplets attached to the baffle 810B, and finally flow back to the mixing chamber 3 through the air inlet 806A. Due to its low density, the smoke can bypass the baffle 810B from the vent 811B after colliding with the baffle 810B and continue to flow into the second air inlet 807B. After entering the second air inlet 807B, it flows out from the air outlet 808B along the smoke path 809B, and finally the filtered smoke flows to the mouthpiece 7 and is inhaled by the consumer.

[0295] When the aerosol separation device 800B needs to be cleaned, it is only necessary to remove the aerosol separation device 800B from the liquid mist filtering smoking device, take out the separator cover 801B and the collision separation structure 803B, and clean them.

[0296] Figure 8-D and Figure 8-EAn embodiment of an aerosol separation device is shown, and the aerosol separation device 800D includes a centrifugal separation structure. The aerosol 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 aerosol separation device 800D can be airtightly installed on the smoke outlet 4 of the liquid mist filtering smoking device through the first sealing ring 804D on the separator cover 801D, and the first sealing ring 804D can 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 airtightness of the aerosol separation device 800D. The second sealing ring 805D can be an O-ring. In addition, sealing fixing methods such as threads and flanges can also be used to facilitate disassembly or cleaning. The centrifugal separation structure 803D is connected to the bottom of the separator cover 801D, and the two can be integrally formed or connected by a detachable structure.

[0297] A first air inlet 806D is provided at the bottom of the separator housing 802D, and the separator cover 801D has an axially penetrating smoke path 809D, with the second air inlet 807D and the air outlet 808D at both ends of the smoke path 809D.

[0298] 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 is wound around the support rod 811D for 3 turns. The pitch and number of spiral turns of the spiral baffle 810D can be adjusted as needed. The adjustment of the pitch and number of spiral turns affects the final aerosol separation effect and the difficulty of suction. The larger the pitch, the worse the aerosol separation effect but the easier it is to suction. The more spiral turns, the better the separation effect but the more difficult it is to suction. Generally, the pitch is not less than 1 mm.

[0299] The outer edge of the spiral baffle 810D can fit almost completely with the inner wall of the separator shell 802D, so the smoke basically does not flow through the gap between the spiral baffle 810D and the separator shell 802D, and the smoke can only flow along the spiral upward airflow channel inside the spiral baffle 810D.

[0300] The mixed smoke formed after the liquid mist and 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, the smoke and moisture will be separated due to the centrifugal effect, and the droplets will condense on the spiral baffle 810D or on 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 pass 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 suction nozzle 7 and is inhaled by the consumer.

[0301] When the aerosol separation device 800D needs to be cleaned, it is only necessary to 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 clean them.

[0302] Figure 8-F and Figure 8-G An embodiment of an aerosol separation device is shown. The aerosol separation device 800F includes a centrifugal separation structure, which is mainly composed of two parts, namely a separator cover 801F and a separator housing 802F. The aerosol separation device 800F can be airtightly installed on 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 sealed and fixed by a 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, a sealing fixing method such as thread and flange can also be used to facilitate disassembly or cleaning.

[0303] The separator cover 801F and the separator shell 802F form a conical space inside, which has a larger first end and a smaller second end. A first air inlet 806F is opened on the side wall of the first end along the tangential direction. The separator cover 801F is provided with an air guide column 811F along the axial direction on the end wall close to the first end. The air inlet end of the air guide column 811F extends toward the bottom of the conical space to form a second air inlet 807F, and the air outlet end of the air guide column 811F extends toward the end wall of the first end to form an air outlet 808F. A smoke path 809F is formed in the middle of the air guide column 811F.

[0304] The mixed smoke formed after the liquid mist and smoke are mixed in the mixing chamber 3 can enter the gas mist separation device 800F through the first air inlet 806F. Since the smoke has a certain initial velocity, under the action of the outer edge of the air guide column 811F and the inner wall of the conical space of the separator shell 802F, it is roughly in a spiral flow state. At this time, the mixed smoke is centrifugal, and part of the water condenses on the inner wall of the separator shell 802F. Since the second air inlet 807F is below and opens downward, the flow state of the mixed smoke is rotating downward. Under the joint action of gravity, the condensed water will flow to the bottom of the separator shell 802F. When the mixed smoke enters the air guide column 811F from the bottom of the conical space, the direction of the airflow changes by about 180°. At this time, due to the large density of the remaining water, most of the water will condense at the bottom of the conical space due to inertia. 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 suction nozzle 7 and is inhaled by the consumer.

[0305] When the aerosol separation device 800F needs to be cleaned, it is only necessary to remove the aerosol separation device 800F from the liquid mist filtering smoking device, take out the separator cover 801F, and clean it.

[0306] 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 parallel or series structures. The two different aerosol separation structures may also be combined together, for example, a baffle for collision separation is provided in the air flow channel of the centrifugal separation structure.

[0307] Figure 9-A An embodiment of a 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, it at least ensures that the waste liquid cannot flow back from the waste liquid chamber 904B to the mixing chamber 3 in a large amount instantly. 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 passing area of ​​the first opening 902A of the waste liquid channel 901A close to the mixing chamber 3 is significantly larger than the passing area of ​​the second opening 903A at the other end. Preferably, the passing area of ​​the first opening 902A is at least twice the passing area of ​​the second opening 903A. When the liquid mist 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 first opening 902A with a larger area and flow into the waste liquid chamber 904A from the second opening 903A. When the liquid mist filtering smoking device is tilted or even inverted due to shaking during carrying, it is difficult for the waste liquid in the waste liquid chamber 904A to flow into the waste liquid channel 901A through the second opening 903A with a smaller area and flow back to the mixing chamber 3 from the first opening 902A.

[0308] Figure 9-B to Figure 9-E An embodiment of a waste liquid collection device is shown, the waste liquid collection device 900B is composed of a cover 908B and a shell 906B, the cover 908B is arranged above the shell 906B, and the space inside the shell 906B below the cover 908B forms a waste liquid chamber 904B. The waste liquid collection device 900B is detachably mounted on the liquid mist filtering smoking device for easy cleaning or replacement. Figure 9-E The state when the waste liquid collection device 900B is installed to the liquid mist filtering smoking device body is shown. The upper outer portion of the housing 906B has a threaded sealing port 909B, and a first sealing strip 910B is arranged above the cover 908B. When the waste liquid collection device 900B is screwed into the liquid mist filtering smoking device body and installed in place, the first sealing strip 910B on the cover 908B cooperates with the liquid mist filtering smoking device body to form a seal.

[0309] The cover 908B can be sealed and connected to the housing 906B through a circumferentially arranged second sealing strip 912B to ensure sealing. The second sealing strip 912B can be arranged on the outside of the cover 908B and / or on the inside of the housing 906B. Figure 9-D The embodiment in which the second sealing strip 912B is arranged on the outside of the cover 908B is shown. The cover 908B can be rigid or flexible, and a more preferred embodiment is to use a soft material such as silicone.

[0310] The connection between the waste liquid collection device 900B and the liquid mist filtering smoking device body can be threaded or flanged, as long as a connection method that can form a sealed environment is sufficient. To facilitate the removal of the waste liquid collection device 900B from the liquid mist filtering smoking device body, a groove 911B can be arranged on the lower outer side of the housing 906B to increase surface friction.

[0311] The waste liquid collection device 900B has an anti-backflow structure, which at least ensures that the waste liquid cannot instantly flow back from the waste liquid chamber 904B to the mixing chamber 3 in large quantities. The cover body 908B includes a first opening 902B and a second opening 903B. The cover body 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 set at the first opening 902B and / or the second opening 903B in the cover body 908B.

[0312] The backflow prevention structure of the waste liquid collection device 900B may include a water absorption portion 907B, and the water absorption portion 907B may be disposed on the cover 908B and / or the waste liquid chamber 904B. Figure 9-B The embodiment in which the water absorption part 907B is arranged on the cover body 908B is shown. The bottom of the cover body 908B is provided with a protrusion 913B and a groove 914B. The groove 914B is connected to the second opening 903B of the cover body 908B. When the water absorption part 907B is arranged on the cover body 908B, the waste liquid can also flow quickly from the groove to the second opening 903B and enter the waste liquid chamber 904B. The water absorption part 907B can be smoothly removed from the cover body 908B and cleaned or replaced. At least a part of the water absorption part 907B is composed of a sponge, a porous body and / or a water-absorbing resin. The volume of the water absorption part 907B and the cover body 908B can be defined by oneself. However, generally only a small volume is required to ensure that the waste liquid will not quickly flow back to the mixing chamber 3 and cause pollution when the liquid mist filtering smoking device is temporarily tilted or even inverted due to carrying and shaking.

[0313] Figure 9-FAn embodiment of a waste liquid collection device is shown. In the waste liquid collection device 900F, the water absorption part 907F and the cover 908F occupy all the internal space of the housing 906F, and the water absorption part 907F completely occupies the space of the waste liquid chamber. Since the water absorption part 907F is completely used to store 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.

[0314] Figure 9-G An embodiment of a waste liquid collection device is shown. A valve 905G is provided below a housing 906G of the waste liquid collection device 900G. When only the waste liquid needs to be poured out, the valve 905G can be opened to allow the waste liquid to flow out of the waste liquid chamber 904G. The valve 905G can be connected to the housing 906G in the form of threads, flanges, or silicone seals.

[0315] Figure 9-H to Figure 9-J An embodiment of a waste liquid collection device is shown. The waste liquid collection device 900H is composed of a cover body 908H and a shell 906H. The cover body 908H is sealed above the shell 906H, and a waste liquid chamber 904H is formed in the space below the cover body 908H inside the shell 906H.

[0316] The waste liquid collection device 900H is detachably mounted on the liquid mist filtering cigarette set for easy cleaning or replacement. The upper outer portion of the housing 906H has a threaded sealing port 909H, and a first sealing strip 910H is arranged above the cover 908H. When the waste liquid collection device 900H is screwed into the main body of the liquid mist filtering cigarette set by means of threads and installed in place, the first sealing strip 910H on the cover 908H cooperates with the main body of the liquid mist filtering cigarette set to form a sealed environment. The cover 908H can be made of soft materials such as silica gel to form the first sealing strip 910H, or it can be connected to the main body of the liquid mist filtering cigarette set by flange, pressure or other sealing methods. The cover 908H can also be made of rigid materials, and a sealing O-ring or the like is attached thereto to form the first sealing strip 910H to ensure sealing.

[0317] The waste liquid collection device 900H has an anti-backflow structure, which at least ensures that the waste liquid cannot instantly flow back from the waste liquid chamber 904H to the mixing chamber 3 in large quantities. 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, and the radius is preferably below 3mm. 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 device is used in different states, it limits the waste liquid from flowing back into the mixing chamber 3. The waste liquid channel 901H can be made of a rigid or soft material. The waste liquid channel 901H can be combined with the cover body 908H into a part or fixed to the cover body 908H by a mechanical connection structure. The second opening 903H of the waste liquid channel 901H should be below 1 / 2 of the height of the waste liquid chamber 904H (in the normal use orientation of the waste liquid chamber 904H, such as Figure 9-H and 9-I As shown in the figure), the more preferred position is below 1 / 3 of the height of the waste liquid chamber 904H, which can limit the backflow of more waste liquid.

[0318] Figure 9-I The waste liquid collecting device 900H is shown in the use state diagram when the liquid mist filtering smoking device is placed normally vertically. 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 waste liquid chamber 904H from the second opening 903H.

[0319] Figure 9-J The diagram shows the use status of the waste liquid collection device 900H when the liquid mist filtering smoking device is abnormally inverted. Due to the effect of gravity, the waste liquid will not remain 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 waste liquid surface, the waste liquid cannot flow out of the waste liquid chamber 904H.

[0320] Figure 9-K An embodiment of a waste liquid collection device is shown. The waste liquid collection device 900K is a variation of the waste liquid collection device 900H. The waste liquid channel 901K can be curved, thus having a labyrinth structure. When the liquid mist filtering smoking device is placed vertically normally, the waste liquid in the mixing chamber 3 can flow into the waste liquid collection device 900K under the action of gravity; and when the liquid mist filtering smoking device is tilted or even inverted due to shaking during carrying, due to the labyrinth structure of the waste liquid channel 901K and the complex pipeline, the probability of waste liquid flowing out is greatly reduced. Even if a small amount of waste liquid flows back into 901K, it is difficult to flow through the entire waste liquid channel 901K and then flow back to the mixing chamber 3 to cause pollution.

[0321] Fig.10An embodiment of a suction nozzle is shown, suction nozzle 1000. The suction nozzle is mainly composed of four parts, namely a connecting seat 1001, a vent pipe 1002, a direction-changing positioning pipe 1003 and a suction nozzle head 1004.

[0322] Among them, the direction-changing positioning tube sleeve 1003 is connected to the outside of the vent pipe 1002, one end of the vent pipe 1002 is connected to the nozzle head 1004, and the other end of the vent pipe 1002 is connected to the connection seat 1001. In another embodiment, the direction-changing positioning tube 1003 and the vent pipe 1002 can be combined into one part by injection molding or welding. The function of the direction-changing positioning tube 1003 is to limit the deformation of the vent pipe 1002, to ensure that the vent pipe 1002 can be bent and arbitrarily changed in direction and positioned, and the direction-changing positioning tube 1003 can be a bellows, a gooseneck tube, a deformed metal hose, etc. In another embodiment, the direction-changing positioning tube 1003 is wound into a spiral spring shape by a metal wire with good plasticity (such as aluminum, silver, copper, etc.), and the diameter of the metal wire can be 0.1~3mm, and the preferred metal wire diameter is 1~2mm. The deformed positioning tube in the above form requires relatively small force when bending, which is more suitable for single-handed adjustment when the smoking device is in use. The specific method can be determined according to the desired feel.

[0323] The function of the connecting base 1001 is to connect the suction nozzle 1000 to the shell of various smoking articles. The connection between the suction nozzle 1000 and the shell of the smoking article can be a threaded connection, a socket connection, a flange, or other connection methods that can ensure airtightness.

[0324] The function of the ventilation pipe 1002 is to allow smoke to pass through, and it needs to meet food safety requirements. It can be in the form of a silicone tube, a latex tube, a plastic corrugated tube, a bendable straw, etc.

[0325] The function of the nozzle head 1004 is to contact with the oral cavity of the consumer and needs to meet food safety requirements. In another embodiment, the nozzle head 1004 can be combined with the ventilation tube as a whole. In another embodiment, the connection base 1001, the ventilation tube 1002 or the nozzle head 1004 is detachable. The advantage of being detachable is that it is easy to replace and clean, because after using the smoking device for a long time, more pollutants will remain in the ventilation tube.

[0326] The suction nozzle 1000 not only meets the suction needs of using the smoking device in different states, but also does not affect the portability of the smoking device.
