Description

Technical Field

[0001] The utility model relates to the technical field of tobacco equipment, in particular to a combined heating appliance. Background Art

[0002] Electric heating devices use heating elements to bake and heat smoking materials to produce aerosols that can be inhaled. Currently, smoking materials are mainly divided into two categories, one is tobacco material and the other is smoke oil material. Usually, an appliance can only heat one flavor of smoking material at a time. At present, electric heating smoking devices that can heat tobacco materials and smoke oil materials at the same time have appeared on the market. The aerosol produced by tobacco materials can retain the original aroma of tobacco to a certain extent, while smoke oil materials can add other types of flavors as a supplement to the tobacco aroma. The mixture of the two aerosols can achieve more flavor combinations.

[0003] At present, in order to achieve the mixing of the two aerosols, the aerosol generated by the e-liquid is usually passed through the smoking section of the heated cigarette to produce mixed smoke. However, the aerosol generated by the e-liquid will be heated twice when passing through the smoking section, which may easily have a bad effect on the taste of the aerosol. At the same time, when the aerosol generated by the e-liquid is heated twice when passing through the smoking section of the cigarette, it may also easily cause bad changes in the taste of the aerosol generated by the smoking section of the cigarette.

[0004] Therefore, how to provide a mixing and heating device that can achieve full mixing of two or more aerosols, enrich the aroma of the inlet aerosol, and maintain the stability of the flavor characteristics of the two aerosols is an urgent problem to be solved by those skilled in the art.

[0043] The side wall of the paper tube of the flavoring mixing section 102 is provided with one or more rows of air inlet holes 103. When the cigarette is inserted into the cigarette heating chamber 7, the air inlet holes 103 and the part of the cigarette below the air inlet holes 103 are located inside the cigarette heating chamber 7, and the air outlet of the aerosol outlet channel 1 is just connected with the air inlet holes 103 of the flavoring mixing section 102, so that the aerosol generated by the atomization of the tobacco oil can enter the flavoring mixing section 102 of the cigarette through the aerosol outlet channel 1 and the air inlet holes 103 on the paper tube, and mix with the aerosol generated by the cigarette, and be inhaled by the user through the cigarette filter.

[0044] The power supply 6 and the electrical system 5 are electrically connected to the cigarette atomization unit and the cigarette oil atomization unit.

[0045] In the combined heating device provided by the utility model, the aerosol generated by the atomization of the e-liquid is mixed with the aerosol generated by the cigarette in the flavoring mixing section 102 of the cigarette, and enters the mouth of the smoker from the filter of the cigarette. The two or more aerosols are fully mixed to enrich the aroma of the inlet aerosol; the atomization of the cigarette and the atomization of the e-liquid are performed separately, and the aerosol generated by the atomization of the e-liquid will not be heated again by the aerosol atomization unit, and the taste of the aerosol generated by the cigarette smoking section 105 will not change, which can keep the flavor characteristics of the two or more aerosols stable, achieve a stable combination of more flavors, and improve the user's smoking experience.

[0046] On the basis of the above specific embodiment, the number of the e-liquid atomization units is multiple, and the overall structure of the cigarette atomization unit is a polygonal cylinder with the same number of the e-liquid atomization units. One surface of each e-liquid atomization unit is fitted and connected to one surface of the cigarette atomization unit. The aerosol outlet channel 1 of each e-liquid atomization unit is provided with a control valve electrically connected to the electrical system 5 for controlling the on-off state of the aerosol outlet channel 1 according to the taste.

[0047] In a specific embodiment, there are multiple e-liquid atomization units, and the flavor of the e-liquid in each e-liquid atomization unit is different, enriching the flavor of the e-liquid. The entirety of the cigarette atomization unit is a polygonal cylinder, and the number of sides of the polygonal cylinder is the same as the number of the e-liquid atomization units. One face of each e-liquid atomization unit is connected to one face of the cigarette atomization unit. For example, there are four e-liquid atomization units, and the entirety of the cigarette atomization unit is a cube. One face of the four e-liquid atomization units is connected to the four faces of the cigarette atomization unit, respectively, and specifically, they can be bonded by an adhesive, connected by a card slot buckle, or connected by screws.

[0048] A control valve is provided on the aerosol outlet channel 1 of each e-liquid atomization unit. The control valve is an electronic valve. The control valve is electrically connected to the electrical system 5. The control valve can control the on and off of the aerosol outlet channel 1. According to the taste selected by the user, one or more corresponding control valves of the electrical system 5 are opened, and the aerosol of the corresponding taste enters the flavoring mixing section 102 for mixing; the control valve that does not match the taste is closed, and the aerosol of the corresponding taste is blocked outside the flavoring mixing section 102.

[0049] In the above embodiment, there are multiple flavors of aerosol mixing and combination modes. The e-liquid aerosols of multiple e-liquid atomization units can be mixed with the cigarette aerosols individually, or two or even multiple flavors of e-liquid aerosols can be mixed with the cigarette aerosols. The switching is convenient and easy to control.

[0050] In another more reliable embodiment, based on any one of the above embodiments, the electrical system 5 is electrically connected to the cigarette heating element and the smoke oil atomization element 4, and the electrical system 5 is preset with a cigarette heating mode, a smoke oil heating mode and multiple groups of mixed suction modes. The electrical system 5 controls the opening state of the cigarette heating element and the smoke oil atomization element 4 to match the selected suction heating mode.

[0051] In a specific embodiment, the electrical system 5 is electrically connected to the cigarette heating element and the tobacco oil atomization element 4, and the electrical system 5 controls the cigarette heating element and the tobacco oil atomization element 4 to turn on or off.

[0052] The electrical system 5 is preset with multiple heating modes, including but not limited to a cigarette-only heating mode, a smoke oil-only heating mode, a mixed smoking mode of any two or more smoke oils, and a set smoke oil and cigarette mixed smoking mode.

[0053] According to the selected flavor, the electrical system 5 controls the matching cigarette heating element and / or the smoke oil atomizing element 4 to heat, and the aerosol of the corresponding flavor enters the flavoring mixing section 102, or the smoke oil aerosol is mixed with the cigarette aerosol, or is inhaled separately; the cigarette heating element and / or the smoke oil atomizing element 4 with incompatible flavor is not heated and no aerosol is generated.

[0054] Exemplarily, the electrical system 5 controls the cigarette heating element and the smoke oil atomization element 4 separately, and the user can choose the suction mode. When the mixed suction mode is selected, the two sets of atomization heating elements start to heat up together to produce a mixed aerosol; when the user selects the heated cigarette mode, the electrical system 5 only outputs power to the heating element of the cigarette heating chamber 7 to heat the tobacco material in the cigarette to produce aerosol. At this time, the atomization element of the smoke oil atomization chamber 3 does not work, and the aerosol flavor is more optional to meet personalized tastes.

[0055] On the basis of the above-mentioned specific embodiments, the cigarette heating element includes a central heating element and / or a peripheral heating element. The central heating element is installed on the bottom surface of the cigarette heating cavity 7. The bottom surface of the cigarette is inserted into the central heating element. There are multiple peripheral heating elements distributed on the side walls of the cigarette heating cavity 7. The electrical system 5 is preset with multiple set temperature curves. The electrical system 5 controls the heating state of each peripheral heating element, the central heating element and the tobacco oil atomization element 4 to match the selected set temperature curve.

[0056] In a specific embodiment, the central heating element is installed on the bottom surface of the cigarette heating cavity 7. The central heating element is in the shape of a slender column. Preferably, the upper end of the central heating element has a pointed tip. When the cigarette is inserted into the cigarette heating cavity 7 from top to bottom, the bottom surface of the cigarette is inserted into the central heating element. The tobacco shreds of the cigarette smoking section 105 are wrapped around the periphery of the central heating element. The interior of the central heating element is contact heated, and the heating is more sufficient.

[0057] There are multiple peripheral heating elements, which are distributed on the side walls of the cigarette heating chamber 7. In the vertical direction, they can be one row or multiple rows; in the circumferential direction, they can be evenly distributed over the entire inner wall or be arranged at intervals.

[0058] The electrical system 5 is preset with a plurality of set temperature curves, and the electrical system 5 is connected to each peripheral heating element, the central heating element, and the e-liquid atomizing element 4. According to the selected set temperature curve, the electrical system 5 controls the matching peripheral heating element, the central heating element, and the e-liquid atomizing element 4 to heat or not heat. Heating according to the set temperature curve improves the smoking experience.

[0059] On the basis of the above-mentioned specific embodiments, the peripheral heating element includes an upper heating element and a lower heating element which are arranged in layers along the vertical direction. The side wall of the cigarette heating chamber 7 is provided with an upper position sensor and a lower position sensor which are respectively adapted to the height of the upper heating element and the lower heating element and are connected to the electrical system 5 for detecting the height of the cigarette. The electrical system 5 is used to control the lower heating element and the upper heating element to turn on when both the lower position sensor and the upper position sensor detect a cigarette; and to control the upper heating element to turn on when only the upper position sensor detects a cigarette.

[0060] In a specific embodiment, the peripheral heating element includes an upper heating element and a lower heating element. In the vertical direction, the heating elements are arranged in layers, with the upper heating element being located at the top and the lower heating element being located at the bottom.

[0061] The side wall of the cigarette heating chamber 7 is provided with an upper position sensor and a lower position sensor, which are respectively adapted to the height of the upper heating element and the lower heating element, and are used to detect the height of the cigarette.

[0062] The upper position sensor and the lower position sensor are both connected to the electrical system 5, and the position sensors feed back the height of the cigarette to the electrical system 5. When both the lower position sensor and the upper position sensor detect a cigarette, it means that the length of the cigarette is long and the lower end of the cigarette can reach the lower position sensor, and the electrical system 5 controls the lower heating element and the upper heating element to turn on at the same time, or controls the lower heating element to turn on alone.

[0063] When only the upper position sensor detects a cigarette and the lower position sensor cannot detect a cigarette, it means that the cigarette is short and the lower end of the cigarette has not reached the lower position sensor. At this time, only the upper heating element is controlled to turn on, and the lower heating element is not turned on. Turning on the heating element is more reasonable and reduces energy consumption.

[0064] On the basis of the above-mentioned specific embodiments, the inner wall and the bottom surface of the cigarette heating chamber 7 are connected by rounded corners, and the bottom surface of the cigarette heating chamber 7 is provided with an in-place sensor electrically connected to the electrical system 5 for detecting whether the inserted cigarette reaches the bottom surface of the cigarette heating chamber 7, and the electrical system 5 is used to emit an in-place prompt sound when receiving the in-place information.

[0065] In a specific embodiment, the connection between the inner wall and the bottom surface of the cigarette heating chamber 7 is a rounded transition. When the cigarette is inserted into the cigarette heating chamber 7, there is a gap between the bottom surface of the cigarette and the rounded corner, which is conducive to external airflow passing through the cigarette.

[0066] The bottom surface of the cigarette heating chamber 7 is provided with a position sensor, which can be a pressure sensor or a camera. When a cigarette is inserted into the bottom surface of the cigarette heating chamber 7 and the bottom surface of the cigarette contacts the bottom surface of the cigarette heating chamber 7, the position sensor senses the pressure of the cigarette or observes that the cigarette reaches the bottom surface of the cigarette heating chamber 7, indicating that the cigarette is installed in the right position in the cigarette heating chamber 7.

[0067] The sensor is electrically connected to the electrical system 5, and the sensor transmits the detected position information to the electrical system 5. When the electrical system 5 receives the position information, it emits a position prompt sound to remind the user to select personalized settings such as heating mode, suction mode, and set temperature curve to prevent misoperation.

[0068] In another more reliable embodiment, based on any of the above embodiments, the air inlet holes 103 are multiple slots arranged around the flavoring mixing section 102, some of which are connected to the cigarette air inlet channel 8, and some of which are connected to the aerosol outlet channel 1;

[0069] In a specific embodiment, the air inlet through hole 103 includes a plurality of slots, and the plurality of slots are arranged in the circumferential direction of the flavoring and mixing section 102. Preferably, the slots are long holes, which are easy to connect with the air outlet of the aerosol outlet channel 1.

[0070] Some of the slots are connected to the cigarette air inlet channel 8 to dilute the aerosol after atomization of the cigarette to meet the aerosol solubility requirements of the cigarette. Some of the slots are connected to the air inlet through hole 103 to achieve mixing of the cigarette aerosol and the smoke oil aerosol.

[0071] In a preferred embodiment, a switch valve is provided on the slot hole, and a concentration sensor for detecting the internal concentration is provided in the flavoring mixing section 102. Both the concentration sensor and the switch valve are electrically connected to the electrical system 5, and the electrical system 5 is used to control the on and off of the switch valve according to the detected concentration value.

[0072] The concentration sensor detects the aerosol concentration in the flavoring mixing section 102, and controls the on-off of each switch valve according to the detected concentration value, the proportion of aerosols of different flavors and personal preferences to ensure a good suction effect and meet the suction requirements of different users.

[0073] Based on the above-mentioned specific embodiments, it also includes an annular seal 9 installed on the inner wall of the cigarette heating chamber 7, the top surface of the cigarette heating chamber 7 is flush with the top surface of the annular seal 9, the annular seal 9 and the cigarette have an interference fit, and the air inlet hole 103 is located below the annular seal 9.

[0074] In a specific embodiment, the annular seal 9 is installed in the cigarette heating chamber 7, and the outer wall of the annular seal 9 is sealed and connected to the inner wall of the cigarette heating chamber 7, and can be connected by an adhesive. The top surface of the cigarette heating chamber 7 is flush with the top surface of the annular seal 9, which is neat and beautiful. The annular seal 9 and the cigarette are interference fit, and the cigarette is loaded into the cigarette heating chamber 7 from the inner hole of the annular seal 9, and the air inlet hole 103 is located below the annular seal 9.
