Description

Technical Field

[0001] This invention relates to the field of heating atomization equipment technology, and particularly to an air intake heating structure, atomizer, and control method. Background Technology

[0002] Commercially available heated atomizers for materials such as tobacco paste and tobacco shreds typically use an inner liner to hold the materials, with heating elements installed on the sides or bottom of the inner liner. These heating elements continuously heat the materials. During inhalation, airflow enters the material chamber of the inner liner through the air inlet of the heated atomizer. The smoke generated by the heated materials flows out from the air outlet and inhalation port with the airflow and is ultimately inhaled by the user.

[0003] To ensure that the material chamber temperature is high enough to atomize the material during inhalation, the heating element needs to continuously heat the material chamber to maintain a stable temperature. However, if the material chamber remains at a high temperature, the surface of the material is prone to charring. In this case, when the user starts inhaling the mist, they will clearly feel a burnt smell, affecting the user's inhalation experience. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an air intake heating structure, an atomizer, and a control method to improve atomization effect and optimize user experience.

[0006] The intake heating structure according to an embodiment of the present invention has at least the following beneficial effects: This invention relates to an air intake heating structure. The material chamber can hold materials such as tobacco paste or tobacco shreds. The base shell can maintain the material chamber at a certain temperature level through other heating methods, preventing the surface of the tobacco paste or tobacco shreds from charring. The first heating component generates heat to maintain the temperature at the first air duct at a high level. Due to the distance between the first air duct and the material chamber, without external factors, the heat from the first air duct will not be significantly transferred to the material chamber, causing a substantial temperature increase. When it is necessary to extract the smoke generated by the material, the user drives the airflow from the air inlet into the first air duct. The airflow is rapidly heated before entering the material chamber. The high-temperature airflow rapidly heats the material in the material chamber, which already has a certain temperature level, causing it to atomize into smoke. The smoke flows out from the air outlet with the airflow. When the user stops driving the airflow, the temperature of the material chamber gradually drops, and the surface of the material will not char. This application improves the atomization effect and optimizes the user experience.

[0012] The atomizer according to embodiments of the present invention has at least the following beneficial effects: The atomizer of the present invention utilizes the air intake heating structure disclosed in any of the above embodiments to improve the atomization effect and optimize the user experience.

[0013] According to some embodiments of the present invention, the base defines a second air duct between the air outlet and the suction port, the base is provided with an auxiliary air outlet and has an auxiliary air duct inside the base, the auxiliary air outlet is connected to the auxiliary air duct, and the auxiliary air duct is connected to the side of the second air duct along the airflow direction.

[0016] According to a third aspect of the present invention, a control method is applied to the intake heating structure disclosed in any of the above embodiments. The control method includes controlling a first heating component to operate and sequentially execute a first preheating step and a first heat preservation step according to a change in operating time. In the first preheating step, the first heating component is started, and the first heating component maintains a first heating temperature for a first time interval. After the first time interval, a second heat preservation step is executed. In the first heat preservation step, the first heating component is controlled to operate at a second heating temperature, wherein the first heating temperature is greater than or equal to the second heating temperature, and the second heating temperature decreases as the operating time increases. The air intake heating structure is further provided with a second heating component.

The second heating component maintains the material chamber at a third heating temperature and a fourth heating temperature that gradually decreases over time. Neither the third nor the fourth heating temperature causes surface charring of the tobacco paste, tobacco shreds, or other materials. Meanwhile, the first heating component maintains the temperature at the first air duct at a higher first heating temperature and a second heating temperature that gradually decreases over time. Because the first air duct and the material... The material chamber has a certain distance between it and the material chamber. Under normal circumstances, without external factors, the heat from the first air duct will not be transferred to the material chamber in large quantities, causing the material chamber to heat up significantly. When it is necessary to extract the smoke generated by the material, the user drives the airflow from the air inlet into the first air duct. The airflow is rapidly heated and then enters the material chamber. The high-temperature airflow will rapidly heat the material in the material chamber, which already has a certain temperature level, thus atomizing it into smoke. The smoke flows out from the air outlet with the airflow. When the user stops driving the airflow, the temperature of the material chamber will gradually drop, and the surface of the material will not char. This application improves the atomization effect and optimizes the user experience.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0025] like Figures 1 to 7 As shown, the air intake heating structure according to a first aspect embodiment of the present invention includes a base shell 100 and a first heating component 140. The base shell 100 is provided with a material cavity 160 for placing material. The base shell 100 has an air inlet 170, an air outlet 180 and a first air duct 190. The air inlet 170, the first air duct 190, the material cavity 160 and the air outlet 180 are sequentially connected to form at least a portion of the atomizing flow channel. The first heating component 140 is disposed on the base shell 100 and is used to heat the airflow flowing through the first air duct 190.

[0026] The base shell 100 can be cylindrical, prismatic, or other irregular shapes. The first heating component 140 can be selected from conventional components such as resistance wires or resistance heating rods. For example, the first heating component 140 can include a carrier plate made of alloy or metal material, on which resistance wires are arranged. The carrier plate has multiple vents and is located in the first air duct 190. When the airflow passes through the first air duct 190, it will pass through the vents, thereby transferring the heat of the resistance wires to the airflow. In addition, a first temperature sensor 610 can be installed on the carrier plate. The first temperature sensor 610 can detect the temperature in the first heating component 140 or the first air duct 190 and control the operation of the first heating component 140 based on the detected temperature feedback.

[0027] In this invention's air intake heating structure, the material chamber 160 can hold materials such as tobacco paste and tobacco shreds. The base shell 100 can maintain the material chamber 160 at a certain temperature level through other heating methods. This temperature will not cause the surface of the tobacco paste, tobacco shreds, etc., to char. The first heating component 140 can generate heat to maintain the temperature at the first air duct 190 at a relatively high level. Since there is a certain distance between the first air duct 190 and the material chamber 160, under the absence of external factors, the heat from the first air duct 190 will not be transferred in large quantities to the material chamber 160, thus preventing the material chamber from charring. The material chamber 160 experiences a significant temperature increase. When it is necessary to extract the smoke generated by the material, the user drives the airflow from the air inlet 170 into the first air duct 190. The airflow is rapidly heated and then enters the material chamber 160. The high-temperature airflow rapidly heats the material in the material chamber 160, which already has a certain temperature level, thus atomizing it into smoke. The smoke flows out from the air outlet 180 with the airflow. When the user stops driving the airflow, the temperature of the material chamber 160 gradually drops, and the surface of the material will not char. This application improves the atomization effect and optimizes the user experience.

[0028] In some embodiments of the present invention, such as Figure 2 As shown, a second heating component 150 is also provided inside the base shell 100. The second heating component 150 is provided for at least one of the side wall and bottom wall of the material cavity 160 so as to heat the material cavity 160.

[0029] The second heating component 150 can also be made of resistance wire or resistance sheet, which meanders and surrounds the outer peripheral wall of the material cavity 160, or is attached to the bottom wall of the outer periphery of the material cavity 160.

[0030] The second heating component 150 can heat the material chamber 160 to maintain the material chamber 160 at a suitable temperature that will not cause the material to char. When the airflow heated by the first heating component 140 enters the material chamber 160, it can work with the airflow to rapidly raise the temperature of the material chamber 160 to a temperature that allows the material to atomize, thereby improving the atomization effect.

[0031] In some embodiments of the present invention, such as Figure 3 As shown, the base shell 100 includes a bottom shell 110 and a cover 130. The bottom shell 110 and the cover 130 are detachably connected and internally define the material cavity 160. The air inlet 170 is opened in the cover 130, and the air outlet 180 is opened in the bottom shell 110. The first heating component 140 is disposed in the cover 130, and the first air duct 190 is defined in the cover 130.

[0032] The cover 130 and the bottom shell 110 can be detachably connected by a threaded structure or a snap-fit ​​structure. The user can separate the cover 130 and the bottom shell 110 to more conveniently clean the material chamber 160 or add materials to the material chamber 160. The cover 130 defines the first air duct 190 and houses the first heating component 140. The first heating component 140 can be repaired or replaced by disassembling the cover 130 separately, reducing maintenance costs.

[0033] In some embodiments of the present invention, the base shell 100 further includes an inner liner 120, the bottom shell 110 is provided with an installation groove 112, the bottom shell 110 is provided with a first ventilation opening 113 communicating with the installation groove 112, the inner liner 120 is provided with a bearing groove 121 and a plurality of second ventilation openings 122 communicating with the bearing groove 121, the inner liner 120 is disposed in the installation groove 112, the first ventilation opening 113 and the second ventilation openings 122 are correspondingly provided to define the air outlet 180, and the cover 130 is covered at the opening of the bearing groove 121 to define the material cavity 160.

[0034] A heat insulation frame 111 can be provided inside the bottom shell 110. The heat insulation frame 111 can be integrally made of materials such as ceramic. The heat insulation frame 111 defines a mounting groove 112. The second heating component 150 can be arranged on the inner peripheral wall, bottom wall, or embedded in the heat insulation frame 111, or, as... Figure 4 As shown, in some embodiments of the present invention, the heat insulation frame 111 may be composed of heat insulation cotton 114 and an outer liner 115. The outer liner 115 defines an installation groove 112. The heat insulation cotton 114 is sleeved on the outer peripheral wall of the outer liner 115. Specifically, the second heating component may be a resistance wire or a resistance sheet disposed on a ceramic component 116, and then the ceramic component 116 is disposed between the heat insulation cotton 114 and the outer liner 115.

[0035] The inner liner 120 is detachably inserted into the mounting slot 112. The inner liner 120 can be made of heat-resistant ceramic, alloy or glass. The second heating component 150 can heat the bearing slot 121 in the inner liner 120. The first vent 113 penetrates the bottom wall of the heat insulation frame 111 and the bottom shell 110. The bottom wall of the inner liner 120 can be provided with multiple second vents 122. The first vent 113 and multiple second vents 122 are located opposite each other. In order to prevent the material from blocking the second vents 122 when the airflow passes through the material chamber 160, multiple partitions 123 can be provided in the inner liner 120. The partitions 123 can be clamped on the material. The airflow can pass through the partitions 123. It should be noted that the tobacco paste, tobacco shreds and other materials do not produce ash or other particulate matter during the heating and atomization process, so they will not be inhaled into the user's mouth with the airflow.

[0036] In some embodiments of the present invention, such as Figure 5 As shown, the cover 130 includes an upper cover 131 and a lower cover 132. The upper cover 131 and the lower cover 132 are connected such that the cavity between the upper cover 131 and the lower cover 132 defines the first air duct 190. The air inlet 170 is opened on the upper cover 131. The lower cover 132 has a plurality of third ventilation openings 133 that communicate with the first air duct 190. When the cover 130 is connected to the bottom shell 110, the third ventilation openings 133 can communicate with the material chamber 160.

[0037] The upper cover 131 and the lower cover 132 can be connected by a threaded structure, a snap-fit ​​structure or screws, etc. The cavity between the upper cover 131 and the lower cover 132 defines the first air duct 190. The lower cover 132 separates the first air duct 190 from the storage chamber. The third vent 133 on the lower cover 132 connects the first air duct 190 and the storage chamber respectively. Furthermore, the upper cover 131 separates the first air duct 190 from the external environment, which can effectively confine the heat emitted by the first heating component 140 in the chamber, reduce heat leakage, reduce power consumption, and also ensure that the heat of the first airflow will not cause the temperature of the storage chamber to rise significantly when there is no airflow. Under the drive of the airflow, the airflow can also be heated quickly when passing through the first air duct 190, and then enter the material chamber 160 through the third vent 133.

[0038] To further improve the heat insulation capacity inside the cover 130, at least one heat insulation sheet 134 made of mica or other materials is provided between the air inlet 170 and the first heating component 140. The heat insulation sheet 134 has an air vent that allows airflow to pass through, thereby effectively preventing the heat generated by the first heating component 140 from leaking outward and storing the heat in the first air duct 190 as much as possible.

[0039] In the atomizer of the second aspect embodiment of the present invention, a base 200 and an air intake heating structure disclosed in any of the above embodiments are included. The base 200 is provided with a suction port 211. The base shell 100 is connected to the base 200 so that the air outlet 180 communicates with the suction port 211.

[0040] The atomizer of the present invention utilizes the air intake heating structure disclosed in any of the above embodiments to improve the atomization effect and optimize the user experience.

[0041] The suction port 211 of the base 200 can be made into a shape that can be sucked by the user's mouth, or the suction port 211 can also be provided with an internal or external thread structure. The user can install water filter accessories, etc. on the base 200 and connect them with the suction port 211, and the smoke can be sucked by the user after passing through the water filter.

[0042] Since the airflow is at a relatively high temperature after passing through the first air duct 190 and the material chamber 160, in order to prevent the user from directly sucking in the high-temperature airflow and causing a risk of burns, in some embodiments of the present invention, the base 200 defines a second air duct 240 between the air outlet 180 and the suction port 211. The base 200 is provided with an auxiliary air outlet 260 and has an auxiliary air duct 250 inside the base 200. The auxiliary air outlet 260 is connected to the auxiliary air duct 250, and the auxiliary air duct 250 is connected to the side of the second air duct 240 along the airflow direction.

[0043] Since the auxiliary air duct 250 is connected to the second air duct 240 along the airflow direction, the user draws the main airflow from the air inlet 170 into the first air duct 190 and the material chamber 160 through the suction port 211. The main airflow has a high temperature and carries smoke. The main airflow will create negative pressure, so that the external airflow can also enter the auxiliary air duct 250 from the auxiliary air port 260 to form an auxiliary airflow. The auxiliary airflow is not heated and has a relatively low temperature. The auxiliary airflow and the main airflow mix at the second air duct 240, which reduces the temperature of the airflow output from the suction port 211, ensuring the user's suction safety and improving the suction experience.

[0044] In some embodiments of the present invention, such as Figure 7 As shown, a smoke guide pipe 230 is provided inside the base 200, and the second air duct 240 is defined inside the smoke guide pipe 230. The first end of the smoke guide pipe 230 is connected to the air outlet 180. The base 200 has a mixing chamber. The auxiliary air outlet 260 and the suction port 211 are both connected to the mixing chamber. The tail end of the smoke guide pipe 230 is connected to the mixing chamber and the tail end of the smoke guide pipe 230 is directly opposite the suction port 211. The mixing chamber is arranged circumferentially around the second air duct 240 along the airflow direction.

[0045] The smoke guide pipe 230 can be made of metal or alloy materials, such as stainless steel. The first end of the smoke guide pipe 230 can be inserted into the first ventilation port 113 to connect with the air outlet 180. The suction port 211 and the auxiliary air outlet 260 can be located on the bottom surface of the base 200. Specifically, the bottom of the base 200 can include a base 210 and a top seat 220. The base 210 and the top seat 220 are connected by a threaded structure or a snap-fit ​​structure to enclose the air mixing chamber. The suction port 211 and the auxiliary air outlet 260 are opened on the base 210, and a fourth ventilation port 221 communicating with the air mixing chamber can also be opened on the top seat 220. The tail end of the smoke guide pipe 230 can be inserted into the fourth ventilation port 221. The tail end of the smoke guide pipe 230 is directly opposite the suction port 211. The main airflow can flow directly out from the suction port 211, while the auxiliary airflow can be evenly mixed in from the circumference.

[0046] As shown in some embodiments 1, 2, and 5 of the present invention, an energy storage module 300 is provided inside the base 200. The energy storage module 300 is used to supply power to at least the first heating component 140. The energy storage module 300 is provided with a clearance opening 310 extending through both ends, and the smoke guide pipe 230 passes through the clearance opening 310.

[0047] The energy storage module 300 can use a conventional battery. Generally speaking, the atomizer is cylindrical or long and irregular in shape. For ease of use, the air intake heating structure is located above the base 200, while the suction port 211 is located below the base 200. The smoke guide tube 230 passes through the clearance port 310, so that the airflow can flow orderly from the top of the atomizer to the bottom of the atomizer.

[0048] For the separable structure between the base 200, the bottom shell 110, and the cover 130, each pair can be provided with a conductive contact structure. The conductive contact structure can include a first conductive block and a second conductive block. Taking the base 200 and the bottom shell 110 as an example, the first conductive block can be set on the base 200 and connected to the energy storage module 300, and the second conductive block is connected to the second heating component 150. When the base 200 and the bottom shell 110 are separated, the first conductive block and the second conductive block are separated. When the base 200 and the bottom shell 110 are connected, the first conductive block and the second conductive block are in conductive contact, and the energy storage module 300 can supply power to the second heating component 150.

[0049] According to a third aspect of the present invention, a control method is applied to the intake heating structure disclosed in any of the above embodiments. The control method includes controlling a first heating component 140 to operate and sequentially execute a first preheating step and a first heat preservation step according to the change of operating time. In the first preheating step, the first heating component 140 is started, and the first heating component 140 is maintained at a first heating temperature for a first time interval. After the first time interval, a second heat preservation step is executed. In the first heat preservation step, the first heating component 140 is controlled to operate at a second heating temperature, wherein the first heating temperature is greater than or equal to the second heating temperature, and the second heating temperature decreases as the operating time increases. The air intake heating structure is further provided with a second heating component 150. The second heating component 150 is provided corresponding to at least one of the side wall and bottom wall of the material cavity 160 to heat the material cavity 160. The control method further includes controlling the operation of the second heating component 150 to sequentially execute a second preheating step and a second heat preservation step according to the change of running time. In the second preheating step, the second heating component 150 is started and maintained at a third heating temperature for a second time interval. After the second time interval, a second heat preservation step is executed. In the second heat preservation step, the second heating component 150 is controlled to operate at a fourth heating temperature. The third heating temperature is greater than or equal to the fourth heating temperature, and the second heating temperature decreases as the running time increases. Furthermore, the first heating temperature is higher than the third heating temperature, and the second heating temperature is higher than the fourth heating temperature during the same running time.

[0050] Specifically, a control module 400 and a control panel 500 can be provided in the base 200. The control panel 500 can be a conventional touch screen or a combination of buttons and a screen. The control module 400 includes a processor such as an MCU or CPU and its auxiliary circuits. The control module 400 also includes a drive unit composed of semiconductor switching transistors. The control module 400 controls the operation of the first heating component 140 and the second heating component 150 through the drive unit. A second temperature sensor 620 for detecting the temperature of the storage chamber is also provided at the second heating component 150. The control module 400 is connected to the first temperature sensor 610, the second temperature sensor 620 and the control panel 500 respectively. The user can set the first heating temperature, the third heating temperature, and the second heating temperature and the fourth heating temperature that decrease with the running time on the control panel 500 according to the actual situation. The user can also set the first time interval and the second time interval.

[0051] Understandably, traditional atomizers only heat the storage chamber. To ensure that the storage chamber can quickly reach a suitable temperature when the user first inhales, allowing the material to form vapor that can be inhaled, the storage chamber needs to be kept at a high temperature. This can result in a burnt taste at the inhalation port. If the temperature is insufficient, the airflow drawn into the storage chamber during inhalation will cause the temperature of the storage chamber to drop further, preventing the user from inhaling the vapor that meets their needs in a timely manner.

[0052] In this application, the first heating component 140 and the second heating component 150 both undergo their respective first and second preheating steps to increase their temperature. The temperature of the top and outer periphery of the material chamber 160 or the bottom of the material chamber increases, so that the tobacco paste, tobacco shreds and other materials can undergo a preliminary reaction and quickly enter a state that can be sucked.

[0053] The first time interval and the second time interval can be the same or different, depending on the user's actual materials or needs. For example, both the first and second time intervals can be set to 0-8 minutes, or the first time interval can be set to 0-6 minutes and the second time interval can be set to 0-8 minutes.

[0054] In the first preheating step and the second preheating step, the control module 400 can control the first heating component 140 and the second heating component 150 to continue heating at a higher temperature, and according to the feedback signals of the first temperature sensor 610 and the second temperature sensor 620, the temperature of the first air duct 190 is maintained at the first heating temperature, and the temperature of the storage chamber is maintained at the third heating temperature.

[0055] After the first and second preheating steps are completed, the user can start to suck up the material. As the operating temperature changes, the temperature required for material atomization will gradually decrease. At this time, in order to prevent the material from charring, the second and fourth heating temperatures will also be reduced. Specifically, when the first preheating step is just completed, the first heating temperature can be equal to the second heating temperature. Similarly, when the second preheating step is just completed, the third heating temperature can be equal to the fourth heating temperature. For example, the first heating temperature can be set to 320℃ and the third heating temperature can be set to 250℃.

[0056] Then, as the running time changes, for example, at 8-10 minutes, the second heating temperature is controlled to decrease to 305℃ at the 10th minute, and the fourth heating temperature is controlled to decrease to 170℃ at the 10th minute; at 10-20 minutes, the second heating temperature is controlled to decrease to 250℃ at the 20th minute, and the fourth heating temperature is controlled to decrease to 155℃ at the 20th minute. The decrease in the second and fourth heating temperatures as the running time increases can be a smooth linear function or a step-like decrease. For example, at 8-9 minutes, the second heating temperature is constant at 320℃, and at 9-10 minutes, the second heating temperature is constant at 305℃. The specific values ​​here are not limited.

[0057] The second heating element 150 maintains the material chamber 160 at a third heating temperature and a fourth heating temperature that gradually decreases over time. Neither the third nor the fourth heating temperature causes surface charring of the tobacco paste, tobacco shreds, or other materials. Meanwhile, the first heating element 140 generates heat to maintain the temperature at the first air duct 190 at a higher first heating temperature and a second heating temperature that gradually decreases over time. Because there is a certain distance between the first air duct 190 and the material chamber 160, without external factors, a large amount of heat from the first air duct 190 will not be transferred to the material chamber 160, thus preventing charring. The material chamber 160 is heated significantly. When it is necessary to extract the smoke generated by the material, the user drives the airflow from the air inlet 170 into the first air duct 190. The airflow is rapidly heated and then enters the material chamber 160. The high-temperature airflow will rapidly heat the material in the material chamber 160, which already has a certain temperature level, thus atomizing it into smoke. The smoke flows out from the air outlet 180 with the airflow. When the user stops driving the airflow, the temperature of the material chamber 160 will gradually drop, and the surface of the material will not char. This application improves the atomization effect and optimizes the user experience.
