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] The health hazards of smoking are widely acknowledged both domestically and internationally. Since tar and other harmful components in cigarette smoke are somewhat water-soluble, water can be used as a filter medium to reduce tar content and mitigate harm. Currently, a variety of waterpipe smoking devices are commercially available that utilize liquid water to filter cigarette smoke. When inhaling, the smoke passes through the water before being inhaled. This method of smoking allows many of the harmful components in the smoke to be filtered out by the liquid, reducing harm to the 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 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 came into being. The main mixing and filtration 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 the consumer.

[0006] During the mixing process of flue gas and liquid mist, most of the liquid mist that absorbs flue gas impurities will condense into waste liquid, and a small amount of liquid mist will still flow with the flue gas. Excessive moisture in the mixed flue gas will affect the user's smoking experience. Summary of the Invention

[0007] The purpose of the present invention is to at least partially remove the moisture contained in the mixed smoke and provide a new liquid mist filtering smoking device with a mist separation function.

[0008] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0009] A liquid mist filtering smoking device with an aerosol separation function comprises a smoke inlet, a liquid mist generating device, a mixing chamber and a smoke outlet, wherein 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; 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 smoke outlet has an aerosol separation device for at least partially separating the smoke and liquid mist in the mixed smoke.

[0010] Furthermore, the aerosol separation device includes a filtering and separation structure arranged on the flow path of the mixed flue gas.

[0011] Furthermore, the filtering and separating structure comprises one or more materials selected from sponge, porous ceramics, metal mesh, non-metal mesh and waterproof breathable membrane.

[0012] Furthermore, the aerosol separation device is a collision separation structure.

[0013] Furthermore, the collision separation structure includes one or more baffles arranged on the flow path of the mixed flue gas, and the baffles are arranged to change the flow path of the mixed flue gas into a tortuous shape.

[0014] Furthermore, the aerosol separation device includes a centrifugal separation structure arranged on the flow path of the mixed flue gas.

[0015] Furthermore, the centrifugal separation structure includes one or more rotating baffles, and the baffles are configured to change the flow path of the mixed flue gas into a spiral shape.

[0016] Furthermore, the centrifugal separation structure includes a conical space having a larger first end and a smaller second end, an air inlet is opened along the tangential direction on the side wall of the first end, and an air guide column is provided along the axial direction on the end wall of the first end, the air inlet end of the air guide column extends toward the bottom of the conical space, and the air outlet end of the air guide column extends toward the end wall of the first end, so that the mixed flue gas at least partially forms a spiral flow path in the conical space.

[0017] Furthermore, the aerosol separation device is arranged in the mixing chamber.

[0018] The present invention designs a liquid mist filtering smoking device with an aerosol separation function, and achieves the effect of separating liquid mist from mixed smoke through different aerosol separation structures, thereby adjusting and improving the user's smoking experience.

[0162] The detailed features and advantages of this patent are described in detail below in the specific implementation method. The content is sufficient to enable any technical personnel in this field to understand the technical content of this patent and implement it accordingly. Based on 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.

[0163] 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 or explained in subsequent drawings.

[0164] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the product is usually placed when in use. These are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this patent.

[0165] In order to make the purpose, technical solutions and advantages of this patent clearer, the implementation methods of this patent will be further described in detail below with reference to the accompanying drawings.

[0166] 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.

[0167] The smoke inlet 1 is connected to the mixing chamber 3. One end of a conventional cigarette filter (not shown) can be inserted into the smoke inlet 1. After the conventional cigarette is lit, 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 from shredded tobacco, tobacco leaves, tobacco flakes, or other combustible materials containing nicotine or nicotine salts. The liquid mist generating device 2 is connected to 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 smoke outlet 4 is connected to the mixing chamber 3. After the liquid mist and smoke mix in the mixing chamber 3, the mixed smoke flows out of the smoke outlet 4. The control system 6 can be used to control the liquid mist generating device 2 on and off, the amount of mist output, etc. The smoke outlet 4 has a suction nozzle 7, through which the consumer can inhale the filtered smoke. The flue gas outlet 4 is equipped with an aerosol separator 8. Since the mixed flue gas flowing directly out of the flue gas outlet 4 after the liquid mist and flue gas mix in the mixing chamber 3 will contain a large amount of liquid mist, the aerosol separator 8 is provided to further separate the liquid mist from the mixed flue gas. After the liquid mist and flue gas mix in the mixing chamber 3 and pass through the aerosol separator 8, a considerable portion of the liquid mist condenses into water droplets that flow to the bottom of the mixing chamber 3, forming waste liquid. A waste liquid collection device 9 is provided below the flue gas mixing chamber 3 and is connected to the bottom of the flue gas mixing chamber 3 to collect the waste liquid in the flue gas mixing chamber 3.

[0168] like Figure 1-B and Figure 1-CAs 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 1-C Modules and arrows are used to further illustrate the flow paths and directions of flue gas and liquid mist between modules.

[0169] Arrow ①: The original smoke generated by the combustion of traditional cigarettes enters the mixing chamber 3 from the smoke inlet 1.

[0170] Arrow ②: waste liquid enters the waste liquid collecting device 9 from the flue gas mixing chamber 3.

[0171] Arrow ③: After the liquid mist and the flue gas are mixed in the mixing chamber 3 , the mixed flue gas enters the mist separation device 8 at the flue gas 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 .

[0172] Arrow ④: The filtered smoke enters the suction nozzle 7 at the smoke outlet 4 and is sucked out.

[0173] Arrow ⑤: The liquid mist generating device 2 atomizes the atomizing liquid into liquid mist and sprays it into the smoke mixing chamber 3.

[0174] Arrow ⑥: The atomized liquid enters the liquid mist generating device 2 from the liquid storage chamber 5.

[0175] Because the liquid mist filtering smoking device covered by this patent involves smoke passages, liquid passages, and circuits, to ensure normal and safe use, the various modules of this type of device must be rationally arranged. On the one hand, overall airtightness must be ensured, and on the other hand, contact between smoke and liquid and the circuits must be prevented, thereby damaging the control system 6 and reducing the service life of the smoking device. Therefore, the passages indicated by the arrows above must be rationally designed and arranged.

[0176] The liquid mist contact module A comprises a smoke inlet 1, a mixing chamber 3, a smoke outlet 4, and a waste liquid collection device 9. The smoke inlet 1 provides an interference fit with a conventional cigarette. The components of the liquid mist contact module are sealed with silicone rings, flange seals, or sealant to ensure airtightness. The components through which the liquid mist flows form a relatively sealed whole, effectively reducing the risk of liquid mist leakage.

[0177] The liquid mist isolation module B includes a liquid mist generating device 2 and a control system 6 .

[0178] 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 this connection port. The liquid mist generating device is set at the connection port by a sealing method, and the sealing method 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 can the liquid mist generated by the liquid storage chamber enter the mixing chamber 3 in the liquid mist contact module A in the form of liquid mist from the one-way channel. The module for contacting the liquid mist and the module for isolating the liquid mist are basically independent and separated, with only one necessary connection port, which effectively protects the control system and extends the service life of the control system.

[0179] The liquid mist isolation module B may further include a control compartment housing the control system 6. The control compartment and the liquid storage chamber 5 are sealed and isolated from each other, thereby preventing the atomized liquid in the liquid storage chamber 5 from flowing into the control compartment and damaging the control system 6. The control compartment is provided with an electrical connection hole, which connects the control system 6 to the liquid mist generating device 2. The electrical connection hole is sealed, including using a sealing ring or silicone filling.

[0180] The above sealing and connection methods are very simple and easy to reuse, replace and expand components.

[0181] Preferably, a flange seal is used between the mixing chamber 3 and the waste liquid collecting device 9 (arrow ②).

[0182] Preferably, the installation connection between the aerosol separation device 8 (arrow ③) and the suction nozzle 7 (arrow ④) is sealed with a flange.

[0183] Preferably, the smoke inlet 1 is provided with a cigarette holder, and the cigarette holder and the mixing chamber 3 are sealed with silicone.

[0184] Preferably, the liquid mist generating device is sealed with the connecting port by silica gel.

[0185] 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.

[0186] 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.

[0187] Figure 5-B The figure shows the smoke channel module of the liquid mist generating device, which 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.

[0188] Figure 5-C The water storage module of the liquid mist generating device is shown. 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 soft material (such as rubber).

[0189] 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.

[0190] When the flue gas enters the mixing chamber and intersects the liquid mist, an angle is formed. The angle can be changed by adding corresponding mechanical structures at the flue gas 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.

[0191] 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.

[0192] The mixed flue gas outlet 204 is connected to the mixing chamber 201, allowing the flue gas and liquid mist to be mixed and filtered in the mixing chamber 201 and then flow out. The condensation waste liquid outlet 205 is connected to the mixing chamber 201, allowing the waste liquid generated by the condensation of the flue gas and liquid mist to flow out.

[0193] An angle β is formed between the direction in which the smoke enters the mixing chamber 201 and the direction in which the liquid mist enters the mixing chamber 201 . The angle β can be changed.

[0194] An angle β is formed between the direction in which the smoke enters the mixing chamber 201 and the direction in which the liquid mist enters the mixing chamber 201 . The angle β can be changed.

[0195] The flue gas 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).

[0196] Preferably, the smoke inlet direction and the liquid mist inlet direction are substantially in the same plane. In this 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 is formed between them. Similarly, the angle β is preferably between 0° and 180°, more preferably 90±10°.

[0197] The smoke inlet 206 is in communication with the mixing chamber 201, and smoke enters the mixing chamber 201 through the smoke inlet 206. The direction of smoke entering the mixing chamber 201 can be changed. The smoke inlet 206 is provided on the cigarette holding component 202, which is adjustably mounted on the mixing chamber 201. The direction of smoke entry changes as the cigarette holding component 202 is adjusted.

[0198] Preferably, a mounting slot is provided between the cigarette clamping component 202 and the wall of the mixing chamber 201 , allowing the cigarette clamping component 202 to slide on the wall of the mixing chamber 201 to change the angle of the smoke entry direction.

[0199] Preferably, the cigarette clamping component 202 is adjusted by a mechanical lever or a motor.

[0200] Preferably, the smoke inlet portion is made of soft materials, such as silicone tubes, latex tubes or gooseneck tubes, and the smoke entry direction is changed by bending the soft material.

[0201] The liquid mist generating device 203 is in communication with the mixing chamber 201. The liquid mist generated by the liquid mist generating device 203 and the smoke mix within the mixing chamber 201, and then flows out of the mixed smoke outlet 204 as filtered smoke. The liquid mist generating device 203 is adjustably mounted on the mixing chamber 201, and the direction of the liquid mist entering changes as the liquid mist generating device 203 is adjusted.

[0202] Preferably, a mounting slot is provided between the liquid mist generating device 203 and the wall of the mixing chamber 201 , allowing the liquid mist generating device 203 to slide on the wall of the mixing chamber 201 to change the angle of the liquid mist entry direction.

[0203] Preferably, the liquid mist generating device 203 is adjusted by a mechanical lever or a motor drive.

[0204] 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.

[0205] Arrow a: direction of smoke entering the mixing chamber 201 .

[0206] Arrow b: direction of liquid mist entering the mixing chamber 201 .

[0207] Arrow c: outflow direction of the mixed flue gas leaving the mixing chamber 201 .

[0208] Arrow d: direction in which waste liquid flows out of the mixing chamber 201 .

[0209] Arrow e: variable direction of the flue gas channel.

[0210] Arrow f: variable direction of liquid mist spray.

[0211] The angle between the flue gas inflow direction and the mixed flue gas outflow direction is α, and the angle between the flue gas inlet direction and the liquid mist inlet direction is β.

[0212] 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, assuming that the physical parameters of cigarette smoke and liquid mist remain basically unchanged and the smoke and liquid mist entry directions are basically in the same plane:

[0213] 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).

[0214] Angle β Smoke composition Unfiltered flue gas About 0° About 90° About 180° Total particulate matter (mg / tube) 13.25 5.75 3.75 3.75 Tar (mg / stick) 11.677 5.00 2.69 3.07 Water content (mg / tube) 0.661 0.58 0.82 0.61 Nicotine (mg / stick) 0.912 0.17 0.24 0.07

[0215] Table 1

[0216] The data in Table 1 shows that when the intersection angle between smoke and liquid mist is around 90°, key smoke filtration indicators perform relatively well. Specifically, tar, a harmful substance, is significantly reduced, while nicotine content is relatively high. Actual puffing experience is largely consistent with the data, indicating that the 90° angle β provides a better puffing experience.

[0217] exist Figure 2-A In one 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.

[0218] The user inputs the required mixed flue gas angle through the user interface, and the information is transmitted to the main control chip.

[0219] The main control chip obtains the current position of the motor rotor using encoder data, position sensor data, and multiple position corrections. It compares the current position of the motor rotor with the angle β entered by the user to obtain the motor drive data. The motor and gear mechanism are linked to drive the liquid mist generator, thereby adjusting the angle β between the inlet direction of the flue gas and the liquid mist.

[0220] During 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, at which time the main control chip stops and locks the motor.

[0221] In one embodiment of the liquid mist filtering smoking article, the liquid mist filtering smoking article includes a smoke inlet, a liquid mist generating device, a mixing chamber, a smoke outlet and a control system.

[0222] 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.

[0223] 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.

[0224] The DC voltage regulator circuit is designed for applications powered by low-voltage energy storage components. For example, if a single-cell battery is used, and the control terminal operating voltage of the DC-AC converter 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 is activated). The purpose of the voltage regulator circuit is to ensure stable mist output. If the voltage regulator circuit is not installed, the atomization effect can still be achieved, but the atomization volume and spray intensity will vary with the voltage.

[0225] 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.

[0226] 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.

[0227] 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 as needed or according to user settings. The output voltage of the voltage adjustment circuit is filtered by the filter circuit and then sent to the DC-AC conversion resonant circuit. The main control chip outputs a PWM signal to modulate the DC-AC conversion resonant circuit. Combined with the feedback signal from 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.

[0228] 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.

[0229] 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. 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.

[0230] like Figure 3-C As shown, when the control system changes the duty cycle of the liquid mist generating device to control the amount of mist output from the liquid mist generating device, the output of the DC voltage regulator circuit is connected to the filter circuit for filtering to make the voltage more stable. The control system also includes a resonant driver chip.

[0231] A regulated power supply, a filter circuit, a DC-AC resonant converter circuit, an atomizer, a resonant driver chip, and a feedback sampling circuit collaborate to complete the atomization function (hereinafter referred to as the atomizer module). The atomizer module has two inputs: a power signal from the filter circuit and an atomizer module control signal from the main control chip. During operation, the atomizer module first converts the DC voltage into an AC signal through the DC-AC resonant converter circuit in conjunction with the modulation signal from the resonant driver chip. The resonant driver chip then adjusts the resonant drive signal based on the DC-AC resonant converter circuit information fed back by the feedback sampling circuit, causing the DC-AC resonant converter circuit to output a stable AC signal. This output AC signal drives the atomizer in the liquid mist generator to atomize the atomized liquid to form filtered liquid mist.

[0232] When the liquid mist power needs to be adjusted, the main control chip modifies the output duty cycle signal, controls the DC voltage regulator circuit or the atomization module to work intermittently, and adjusts the average power value per unit time.

[0233] In one 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 communicates with the mixing chamber, allowing smoke to enter the mixing chamber from the smoke inlet; the smoke outlet communicates with the mixing chamber; the liquid mist generating device communicates with the mixing chamber; the liquid mist generated by the liquid mist generating device and smoke mix in the mixing chamber before flowing out of the smoke outlet to form filtered smoke; and the control system is used to control the mist output pattern of the liquid mist generating device.

[0234] like Figure 4-A As shown in Figure 2, the input of a control system is broadly divided into circuit input and material input.

[0235] Material input: The main working method of liquid mist filtering smoking devices is to filter and absorb traditional cigarette smoke through atomized liquid. Therefore, the material input has two parts: one is cigarette smoke and the other is liquid mist.

[0236] Circuit input: including liquid mist components, filtration method and flue gas related signals, etc.

[0237] The filtration method refers to the need to perform a gas-liquid separation process on the mixed gas at the front end of the suction nozzle after the flue gas 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.

[0238] 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.

[0239] 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 components of the liquid mist.

[0240] The particle size and power of the liquid mist can be controlled by the electrical parameters of the atomizing element. Currently, three main atomization methods are used: ultrasonic, jet, and pressure atomization. The circuit system adjusts the voltage, frequency, and duty cycle based on input. The direction of the liquid mist spray is determined by converting a position sensor into an electrical signal. The liquid mist composition is determined by the consumer, who can select the appropriate atomized matrix with different flavorings and other additives.

[0241] When cigarette smoke is input, in addition to the material input, the information it carries needs to be used as circuit input.

[0242] like Figure 4-B As shown, the smoke signal input by the circuit includes physical quantities such as cigarette type, puff volume, smoke flow rate, and the direction of smoke entering the mixing chamber. Cigarette types can be categorized in two ways: by brand and by primary ingredient (e.g., cut leaves, cut stems, flakes, etc.). These parameters can be pre-entered into the smoking device's control system by the user, or the device can automatically identify cigarette information (e.g., cigarette logo, barcode, QR code, etc.). Puff volume and smoke flow rate can be converted into electrical signals by a flow sensor attached to the smoking device during a consumer's puff, and airflow direction can be converted into an electrical signal by, for example, a position sensor.

[0243] After the input enters the circuit system, the circuit system calculates the corresponding electrical signal to control the output of the liquid mist.

[0244] like Figure 4-CThe 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.

[0245] After receiving 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.

[0246] The input module includes one or more of a touch screen, keyboard, knob, switch, and sensor, and is used to capture user input information and transmit it to the main control chip. Input information includes one or more of the following: power on / off signal, gear position, tobacco type, liquid aerosol type, smoke moisture content, smoke temperature, nicotine content, airflow rate, air flow velocity, and air pressure.

[0247] 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 user feedback on system status. The output information includes one or more of the following: operating status, gear position, battery level, charging indicator, low battery warning, tobacco type, liquid aerosol generating agent type, smoke moisture content, smoke temperature, nicotine content, airflow rate, airflow velocity, and air pressure.

[0248] 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 atomizer in the liquid mist generating device to form a complete atomization function, achieving atomization of the target substance.

[0249] The working principle of an atomizer is briefly described as follows: 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.

[0250] The control steps of the control system are:

[0251] Step 1: The input module obtains input information in the cigarette preparation state;

[0252] Step 2: The input module obtains input information of the cigarette in the lit state;

[0253] Step 3: The main control chip generates a control signal, and the atomization circuit module starts atomization;

[0254] Step 4: The input module updates the input information;

[0255] Step 5: The control system adjusts the control signal based on the input information obtained in step 4 and updates it to the atomization circuit module;

[0256] Step ⑥ Repeat step ⑤ until the operation is completed.

[0257] The control system can calculate the electrical signal to be controlled by system lookup table or empirical function. When the control system uses the system lookup table method, the main control chip stores the corresponding table of input information and control signals.

[0258] like Figure 4-D As shown, the specific working process of the control system in one embodiment is as follows:

[0259] After starting the liquid mist filtering smoking device, the input module obtains the liquid mist generating agent type and cigarette type. Using the liquid mist generating agent as the X-axis and the cigarette type as the Y-axis, the initial atomization power is found through a two-dimensional table lookup method, as shown in Table 2:

[0260] Cigarette type 1 …… Cigarette type n Liquid mist generating agent 1 P11 …… P1n Liquid mist generator 2 P21 …… P2n Liquid mist generating agent 3 P31 …… P3n Liquid mist generating agent 4 P41 …… P4n

[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 monitors the smoke moisture parameters, smoke temperature, and smoke volume parameters in real time. It then 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 are obtained, or until the operation is completed.

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

[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 operating parameters of the liquid mist filtering smoking device to ensure its safe operation. The operation monitoring system may include a main control chip, an atomization circuit, and a liquid level detection circuit. 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 plate 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 may be 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 liquid level sensor should be positioned 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 atomized liquid amount is insufficient, the main control chip turns off 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 operating 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 volume of the liquid mist generating device. The main control chip integrates the received atomization volume over time and compares the integral value with a preset low-liquid threshold. When the integral value falls below the low-liquid 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 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 falls below 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 independently.

[0276] like Figure 7-A As shown, the smoke inlet 1 can be an elastic cigarette holder, which is formed in one piece. In fact, each feature can be disassembled into parts and assembled into an integral component to complete the function. Here, the state of a single part is used for explanation.

[0277] 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.

[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 airtightness, 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, the 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 facilitate the user to pry the elastic cigarette holder, so that the cigarette bin is quickly displaced due to the elastic effect of the elastic flue, thereby shaking off the cigarette ash.

[0280] The base 702, located at the rear end of the elastic cigarette holder, is used to connect to the smoking device, securing the elastic cigarette holder to the smoking device. A securing clip is provided on the base to secure the elastic cigarette holder to the smoking device. The base is made of elastic material and has an interference fit with the mounting holes of the smoking device.

[0281] The base has an axial stopper 707 in front of the fixing clip. 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. A circumferential stopper 708 is located above the axial stopper to limit the installation direction of the elastic cigarette holder, ensuring that the angle of the pick is suitable for the user.

[0282] The elastic flue 703 is a hollow tube made of elastic material that connects the cigarette compartment 701 to the base 702. The elastic flue has a certain degree of flexibility, allowing the cigarette compartment to move relative to the base when the user moves the cigarette compartment. The elastic material has a hardness 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 compartment rebounds quickly after the paddle is moved.

[0283] like Figure 7-B As shown, the inner diameter of the cigarette bin 701 is larger than the inner diameters of the base 702 and the elastic channel 703. Due to the inner diameter difference, a circular hollow positioning platform 709 is formed at the bottom of the cigarette bin to prevent cigarettes from entering the elastic flue while ensuring that cigarettes do not affect the deformation of the elastic flue.

[0284] When in use, insert the cigarette into the cigarette chamber and smoke it normally. When you need to shake off the ash, just use the fingers of the hand holding the device to move the pick, so that the cigarette chamber will produce a certain rapid displacement to shake off the ash. After releasing your hand, the cigarette chamber will return to its original position due to the elastic effect. Using this ash shaking device, you can easily operate it with one hand like shaking off 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. The aerosol separation device 800A includes a filter separation structure. The aerosol separation device 800A mainly consists of three parts: a separator cover 801A, a separator housing 802A, and a filter separation structure 803A. The aerosol separation device 800A can be airtightly mounted on the smoke outlet 4 of the liquid mist filtering smoking device via a first sealing ring 804A on the separator cover 801A. 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, or alternatively, a threaded or flanged sealing method can 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 both ends of the smoke path 809A respectively. The mixed smoke formed after the liquid mist and smoke are mixed 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, 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 passing through the filtering and separation structure 803A, the smoke 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. The absorption filter material 803A can also be removed and replaced or cleaned.

[0290] Figure 8-B and Figure 8-CAn embodiment of an aerosol separation device is shown, in which 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 smoke outlet 4 of the liquid mist filtering smoking device through a 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 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. The two can be formed as one piece or connected using 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 multi-layer collision baffle assembly 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 multiple baffles 810B evenly distributed in the circumferential direction. Figure 8-C There are three implementation methods in the embodiment, and vents 811B are formed between the baffles 810B. The baffles on the two adjacent layers of collision baffle groups are staggered, that is, from the axial direction, the vents of a collision baffle group on a certain layer are opposite to the baffles of the collision baffle group on the next layer. The position and shape of the baffles and vents in each layer of collision baffle group, as well as 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 basically completely fit with the inner wall of the separator shell 802B, so the smoke basically will not flow through the gap between the baffle 810B and the separator shell 802B. 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 mix 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, due to its high density, cannot continue to flow through after colliding with the baffle 810B. It easily condenses into droplets that adhere to the baffle 810B and eventually flows back into the mixing chamber 3 through the air inlet 806A. Due to its low density, after colliding with the baffle 810B, the smoke can bypass the baffle 810B through the vent 811B and continue to flow into the second air inlet 807B. After entering the second air inlet 807B, it flows along the smoke path 809B and out of the air outlet 808B. 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-E An embodiment of an aerosol separation device is shown, in which the aerosol separation device 800D includes a centrifugal separation structure. The aerosol separation device 800D mainly consists of three parts: a separator cover 801D, a separator housing 802D, and a centrifugal separation structure 803D. The aerosol separation device 800D can be airtightly mounted on the smoke outlet 4 of the liquid mist filtering smoking device via a 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 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. Alternatively, a threaded or flanged sealing method can be used to facilitate disassembly or cleaning. The centrifugal separation structure 803D is connected to the bottom of the separator cover 801D. The two can be integrally formed or connected using 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 a second air inlet 807D and an 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-DIn the embodiment, the spiral baffle 810D is wound three times around the support rod 811D. The pitch and number of spiral turns of the spiral baffle 810D can be adjusted as needed. Adjusting the pitch and number of spiral turns affects the final aerosol separation effect and the ease of suction. A larger pitch results in poorer aerosol separation effect but easier suction. A larger number of spiral turns results in better separation effect but more difficult suction. The pitch is generally no less than 1 mm.

[0299] The outer edge of the spiral baffle 810D can basically completely fit with the inner wall of the separator shell 802D, so the smoke basically will not flow through the gap between the spiral baffle 810D and the separator shell 802D. 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 mix in the mixing chamber 3 can enter the mist 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 water 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 eventually flow back to the mixing chamber 3 through the air inlet 806A. The smoke can then follow the air flow channel through the spiral baffle 810D and continue to flow toward 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.

[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 separator 800F is shown. The aerosol separator 800F includes a centrifugal separation structure and is primarily composed of two parts: a separator cover 801F and a separator housing 802F. The aerosol separator 800F can be airtightly mounted to the smoke outlet 4 of the liquid mist filtering smoking device via a first sealing ring 804F on the separator cover 801F. The first sealing ring 804F can be an O-ring. A second sealing ring 805F seals the separator cover 801F and the separator housing 802F to maintain airtightness. The second sealing ring 805F can be an O-ring, but threads, flanges, or other sealing methods can also be used to facilitate disassembly and 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 near 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 flue gas path 809F is formed in the middle of the air guide column 811F.

[0304] After the liquid mist and flue gas mix in mixing chamber 3, the resulting mixed flue gas enters the aerosol separator 800F through the first air inlet 806F. Due to the flue gas's initial velocity, it adopts a roughly spiraling flow pattern under the influence of the outer edge of the air guide column 811F and the inner wall of the conical space of the separator housing 802F. At this point, the mixed flue gas is subjected to centrifugal force, causing some moisture to condense on the inner wall of the separator housing 802F. Because the second air inlet 807F is located below and opens downward, the mixed flue gas flows in a spiraling downward pattern. Combined with gravity, the condensed moisture flows to the bottom of the separator housing 802F. When the mixed flue gas enters the air guide column 811F from the bottom of the conical space, the airflow undergoes an approximately 180° turn. At this point, due to the high density of the remaining moisture, most of the moisture condenses at the bottom of the conical space due to inertia. After entering the second air inlet 807F, the smoke 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.

[0305] When the aerosol separator 800F needs to be cleaned, it is only necessary to remove the aerosol separator 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 connected in parallel or in series. The two different aerosol separation structures may also be combined, for example, by providing a baffle for collision separation in the airflow channel of the centrifugal separation structure.

[0307] Figure 9-AAn embodiment of a waste liquid collection device is shown. The waste liquid collection device 900A includes a backflow prevention structure and a waste liquid chamber 904A. The backflow prevention structure is used to at least partially prevent waste liquid from flowing back from the waste liquid chamber 904B into the mixing chamber 3. For example, it at least ensures that waste liquid cannot instantly flow back into the mixing chamber 3 in large quantities from the waste liquid chamber 904B. The waste liquid chamber 904A provides sufficient capacity to accommodate the waste liquid. The backflow prevention structure includes a waste liquid channel 901A connecting the waste liquid chamber 904A and the mixing chamber 3. The first opening 902A of the waste liquid channel 901A near the mixing chamber 3 has a significantly larger passage area than 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 mist filtering smoking device is properly placed vertically, waste liquid in the mixing chamber 3 easily flows into the waste liquid channel 901A through the larger first opening 902A and then 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. Waste liquid collection device 900B comprises a cover 908B and a housing 906B. Cover 908B is positioned above housing 906B, and the space within housing 906B below cover 908B forms a waste liquid chamber 904B. Waste liquid collection device 900B is detachably mounted on a liquid mist filtering smoking device for easy cleaning or replacement. Figure 9-E The waste liquid collection device 900B is shown installed in the main body of the liquid mist filtering device. The outer upper portion of the housing 906B has a threaded sealing opening 909B, and a first sealing strip 910B is positioned above the cover 908B. When the waste liquid collection device 900B is screwed into the main body of the liquid mist filtering device and properly installed, the first sealing strip 910B on the cover 908B engages with the main body of the liquid mist filtering device, forming a seal.

[0309] The cover 908B can be sealed to the housing 906B via 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 disposed on the outside of the cover 908B is shown. The cover 908B can be rigid or flexible, and is preferably made of a soft material such as silicone.

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

[0311] The waste liquid collection device 900B has a backflow prevention structure, which at least prevents waste liquid from instantly flowing back into the mixing chamber 3 from the waste liquid chamber 904B in large quantities. The cover 908B includes a first opening 902B and a second opening 903B, forming a waste liquid channel. The area of the waste liquid channel near the first opening 902B of 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 provided in the cover 908B at the first opening 902B and / or the second opening 903B.

[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 provided on the cover 908B and / or the waste liquid chamber 904B. Figure 9-B The embodiment shows a water absorption portion 907B disposed on the cover 908B. The bottom of the cover 908B is provided with a protrusion 913B and a groove 914B. The groove 914B is connected to the second opening 903B of the cover 908B. When the water absorption portion 907B is disposed on the cover 908B, waste liquid can also flow quickly from the groove to the second opening 903B and enter the waste liquid chamber 904B. The water absorption portion 907B can be easily removed from the cover 908B for cleaning or replacement. At least a portion of the water absorption portion 907B is composed of a sponge, a porous body, and / or a water-absorbing resin. The volume of the water absorption portion 907B and the cover 908B can be customized. However, generally, only a small volume is required to ensure that waste liquid does not quickly flow back into the mixing chamber 3 and cause contamination when the liquid mist filtering smoking device is temporarily tilted or even inverted due to shaking during carrying.

[0313] Figure 9-F An embodiment of a waste liquid collection device is shown. In waste liquid collection device 900F, a water absorption portion 907F and a cover 908F occupy the entire interior space of housing 906F, with the water absorption portion 907F completely occupying the waste liquid chamber. Because the waste liquid is stored entirely within the water absorption portion 907F, violent shaking, prolonged tilting, or even inversion of the device prevents the waste liquid from rapidly flowing back into mixing chamber 3 and causing contamination.

[0314] Figure 9-GAn embodiment of a waste liquid collection device is shown. Waste liquid collection device 900G is provided with a valve 905G below housing 906G. To discard waste liquid, valve 905G can be opened to allow the waste liquid to flow out of waste liquid chamber 904G. Valve 905G can be connected to housing 906G using 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 908H and a shell 906H. The cover 908H is sealed above the shell 906H, and the space below the cover 908H inside the shell 906H forms a waste liquid chamber 904H.

[0316] The waste liquid collection device 900H is removably mounted on the liquid mist filter for easy cleaning or replacement. The outer upper portion of the housing 906H has a threaded sealing opening 909H, and a first sealing strip 910H is positioned above the cover 908H. When the waste liquid collection device 900H is screwed into the main body of the liquid mist filter and installed, the first sealing strip 910H on the cover 908H cooperates with the main body of the liquid mist filter to form a sealed environment. The cover 908H can be made of a soft material such as silicone to form the first sealing strip 910H, or it can be connected to the main body of the liquid mist filter using a flange, pressure seal, or other sealing method. The cover 908H can also be made of a rigid material, with a sealing O-ring or the like attached 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 aperture of the waste liquid channel 901H, the first opening 902H and the second opening 903H is relatively small, and the radius is preferably less than 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 one 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), the 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-IThe waste liquid collecting device 900H is shown in the usage state diagram when the liquid mist filtering smoking device is normally placed 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 figure shows the usage 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. Waste liquid collection device 900K is a variation of waste liquid collection device 900H. Waste liquid channel 901K can be curved, thus forming a maze structure. When the mist filtering smoking device is normally placed upright, waste liquid in mixing chamber 3 can flow into waste liquid collection device 900K under the action of gravity. However, when the mist filtering smoking device tilts or even inverts due to movement during transportation, the maze structure and complex piping of waste liquid channel 901K greatly reduce the probability of waste liquid flowing out. Even if a small amount of waste liquid flows back into 901K, it is unlikely to flow through the entire waste liquid channel 901K and then back into mixing chamber 3, causing contamination.

[0321] Figure 10 FIG. 1 is a diagram showing an embodiment of a suction nozzle, namely, a suction nozzle 1000 . The suction nozzle is mainly composed of four parts, namely, a connecting base 1001 , a vent pipe 1002 , a direction-changing positioning pipe 1003 and a nozzle head 1004 .

[0322] The reversible positioning tube sleeve 1003 is attached to the outside of the vent tube 1002. One end of the vent tube 1002 is connected to the mouthpiece 1004, and the other end of the vent tube 1002 is connected to the connector 1001. In another embodiment, the reversible positioning tube 1003 and the vent tube 1002 can be combined into a single component through methods such as injection molding or welding. The reversible positioning tube 1003 functions to limit the deformation of the vent tube 1002, ensuring that it can be bent and positioned arbitrarily. The reversible positioning tube 1003 can be formed into a corrugated tube, a gooseneck tube, a deformable metal hose, or the like. In another embodiment, the reversible positioning tube 1003 is made of a highly malleable metal wire (such as aluminum, silver, or copper) wound into a spiral spring shape. The wire diameter can range from 0.1 to 3 mm, with a preferred diameter of 1 to 2 mm. This type of deformable positioning tube requires relatively little force to bend, making it more suitable for single-handed adjustment during use of the smoking device. The specific design can be determined based on the desired feel.

[0323] The function of the connecting base 1001 is to connect the mouthpiece 1000 to the housing of various smoking devices. The connection between the mouthpiece 1000 and the housing of the smoking device can be a threaded connection, a socket connection, a flange connection, or other connection methods that can ensure airtightness.

[0324] The function of the vent 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 bellows, a flexible straw, etc.

[0325] The nozzle head 1004 is designed to come into contact with the consumer's oral cavity and must meet food safety requirements. In another embodiment, the nozzle head 1004 can be integrated with the vent tube. In another embodiment, the connector 1001, vent tube 1002, or the nozzle head 1004 can be detachable. This detachable design facilitates replacement and cleaning, as prolonged use of the smoking device can leave a significant amount of contaminants in the vent tube.

[0326] The 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.
