Description
Technical Field
[0001] The present invention relates to the field of electronic products, and in particular to an electronic cigarette. Background Art
[0002] Electronic cigarettes are electronic products that imitate cigarettes. Currently, cartridge-type electronic cigarettes are a more common type of electronic cigarette. The cartridge and cigarette rod of this type of electronic cigarette exist in a separate form. The cigarette rod and cartridge that match each other are detachably fixed to each other to form the cartridge-type electronic cigarette. An atomizer for atomizing the smoke oil is set in the cartridge. Users can choose smoke oil with different flavors by replacing different cartridges during use, thereby experiencing different atomization flavors.
[0003] In the process of using cartridge-changing electronic cigarettes, users will buy cartridges of different flavors of the same model of cartridge-changing electronic cigarettes. These cartridges are very easy to confuse during storage and use, resulting in poor user experience. In addition, users may also purchase cartridge-changing electronic cigarettes of different models of the same brand or cartridge-changing electronic cigarettes of different brands. At present, the structures of cartridges and cigarette rods of cartridge-changing electronic cigarettes of the same brand but different models or different brands are basically similar, which makes it very easy for users to assemble mismatched cartridges and cigarette rods, which not only brings great inconvenience to users, but also shortens the service life of electronic cigarettes. Therefore, intelligent identification of cartridges is imminent.
[0004] At present, the identification technology of the cartridge of the replaceable electronic cigarette in the cigarette rod generally adopts to add a chip inside the cartridge to record the cartridge information and read the cartridge information through the data interface of the cigarette rod to identify the cartridge. However, this identification technology is costly and complicated in process, resulting in a significant increase in the hardware cost of the cartridge. In addition, the chip only has the identification function and cannot control the operation of the atomizer according to the identification result, resulting in a relatively single working mode of the atomizer and unable to obtain the atomization effect corresponding to different cartridges.
[0005] Therefore, there is an urgent need to provide an electronic cigarette with low identification cost, simple process, greatly reduced hardware cost of cigarette cartridges, and the ability to obtain targeted atomization effects. Summary of the invention
[0006] In view of the deficiencies of the above-mentioned prior art, the present invention provides an electronic cigarette, in which a first electrical contact device and a second electrical contact device are respectively arranged on the cigarette rod and the cigarette cartridge, and the matching condition between the cigarette cartridge and the cigarette rod is judged by comparing the actual connection state of the first electrical contact and the second electrical contact with the preset connection state through a controller, and the controller can control the working mode of the atomizer according to the matching condition.
[0007] To achieve the above-mentioned one purpose, the present invention provides an electronic cigarette, which includes a cigarette rod and a cigarette cartridge. The cigarette rod includes: a battery, a controller electrically connected to the battery, and a first electrical contact device having at least one first electrical contact. The cigarette cartridge includes: an atomizer and a second electrical contact device having a second electrical contact electrically connected to the first electrical contact. When the cigarette rod and the cigarette cartridge are detachably fixed, the first electrical contact and the second electrical contact are in an actual connection state, and the atomizer is electrically connected to the second electrical contact device and is electrically connected to the controller through the actual connection state. The controller includes a comparison module, a control module, and a storage module storing a plurality of preset connection states and a plurality of atomizer working parameters corresponding to the plurality of preset connection states. The comparison module obtains the actual connection state, and then compares the actual connection state with the plurality of preset connection states and judges the matching of the atomizer and the cigarette rod according to the comparison result. When the comparison module compares that the actual connection state is the same as the first preset connection state in the plurality of preset connection states, the control module controls the working mode of the atomizer according to the first atomizer working parameter corresponding to the first preset connection state.
[0008] Furthermore, the number of the first electrical contacts is a, the number of the second electrical contacts is b, a and b are natural numbers, and the number N of the preset connection states satisfies: N≤2 a -1, and a and b satisfy: 0<b≤a, a≥1. When the actual connection state is one of the N preset connection states, the comparison module determines that the match is matched; when the actual connection state is not any of the N preset connection states, the comparison module determines that the match is not matched.
[0009] Further, if the matching situation is a match, the control module controls the atomizer to work normally in the corresponding working mode; if the matching situation is a mismatch, the control module executes an alarm or prohibits the atomizer from working normally.
[0010] Furthermore, the number of the first electrical contacts is at least two, and one of the first electrical contacts is used for the comparison module to judge the authenticity of the atomizer.
[0011] Furthermore, when the matching situation is a match, the comparison module compares the first actual connection situation between one of the first electrical contacts and the second electrical contact and the second actual connection situation between at least one other first contact and the corresponding second electrical contact with multiple preset connection states, and determines the authenticity of the atomizer and the working mode of the atomizer according to the comparison results.
[0012] Furthermore, the working mode of the atomizer includes one or more of heating duration, heating temperature and heating frequency.
[0013] Furthermore, the first electrical contact device is a circuit board provided with a spring-pin type first electrical contact, and the second electrical contact device is an FPC.
[0014] Furthermore, a positioning hole is provided in the middle of the FPC, a clamping column matching the positioning hole is provided on the cigarette rod, the first electrical contact is provided on the periphery of the clamping column, and the second electrical contact is provided on the periphery of the positioning hole.
[0015] Furthermore, a groove is provided on the FPC, and a protrusion matching with the groove is provided on the circuit board.
[0016] Furthermore, the opposite surfaces of the cigarette rod and the cigarette cartridge for detachable fixation are respectively provided with a recess and a protrusion with a substantially elliptical cross-section, and the recess is used to accommodate the FPC therein.
[0017] The beneficial effects of the present invention are: the identification cost of the electronic cigarette is low, the process is simple, and a targeted atomization effect can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0024] refer to Figures 1 to 3The present invention provides an electronic cigarette 100, which includes a cigarette rod 10 and a cigarette cartridge 20. Generally, a cigarette rod 10 of one model can be matched with a plurality of different types of cigarette cartridges 20, so that the user can experience different flavors of e-liquid. Therefore, the user generally has multiple cigarette cartridges 20. When the electronic cigarette 100 is not in use, the cigarette rod 10 and the cigarette cartridge 20 are often in a separated state, and multiple cigarette cartridges 20 are easily confused during storage. When the electronic cigarette 100 is in use, the cigarette rod 10 and the cigarette cartridge 20 are detachably fixed, and the cigarette rod 10 and the cigarette cartridge 20 need to match to work properly. Specifically, the cigarette rod 10 includes a battery, a controller electrically connected to the battery, and a first electrical contact device 11 having at least one first electrical contact 11A. It should be understood that the above-mentioned electrical connection with the battery can be either the controller and the first electrical contact device 11 are electrically connected to the battery in parallel through different circuits or they are electrically connected to the battery in series through the same circuit, as long as the controller can compare and judge the connection status of the first electrical contact device 11 and the second electrical contact device 21. The controller may be a CPU, a PLC, etc. The cartridge 20 includes: an atomizer (not shown) and a second electrical contact device 21 having a second electrical contact 21A electrically connected to the first electrical contact 11A. When the cigarette rod 10 and the cartridge 20 are detachably fixed, the first electrical contact 11A and the second electrical contact 21A are in an actual connection state, and the actual connection state includes the second electrical contact 21A being in contact with the first electrical contact 11A or at least one second electrical contact 21A not being in contact with the first electrical contact 11A. The corresponding circuit conduction is achieved by the relative contact of each pair of second electrical contacts 21A and the first electrical contact 11A in the matching state. The atomizer is electrically connected to the second electrical contact device 21 and is electrically connected to the controller through the actual connection state. That is, the atomizer is electrically connected to the controller only in the actual connection state corresponding to the matching with the cigarette rod 10 and the cartridge 20. In addition, it is known that a cigarette tank for storing tobacco oil is also provided in the cartridge 20, and the atomizer atomizes the tobacco oil. It should be noted that the controller can be electrically connected to the battery through two circuits, that is, one circuit is for the controller to be electrically connected to the battery alone, and the other circuit is for the second electrical contact 21A and the first electrical contact 11A in the actual connection state when the cigarette rod 10 and the cigarette cartridge 20 are matched to be electrically connected to the battery in parallel. In this way, in the above-mentioned separation state, the controller can control the display provided on the cigarette rod 10 and electrically connected to the battery to display information such as the type of cigarette cartridge that the cigarette rod 10 can match and the duration of using various types of cigarette cartridges. In the above-mentioned detachable fixed state, the controller can control the operation of the electronic cigarette 100, especially the atomizer. In addition, the controller includes a comparison module, a control module, and a storage module storing a plurality of preset connection states and a plurality of atomizer operating parameters corresponding to the plurality of preset connection states, and the preset connection state includes various situations of whether each first electrical contact 11A is in contact with the second electrical contact 21A.The comparison module obtains the actual connection state, and then compares the actual connection state with a plurality of preset connection states and determines the matching of the atomizer and then the cigarette cartridge 20 with the cigarette rod 10 according to the comparison result. When the comparison module compares the actual connection state with the first preset connection state among the plurality of preset connection states, the control module controls the working mode of the atomizer according to the first atomizer working parameter corresponding to the first preset connection state. That is to say, the comparison module compares the actual connection state with the plurality of preset connection states. When the actual connection state is the same as one of the preset connection states, the control module controls the working mode of the atomizer with the first atomizer working parameter corresponding to the one of the preset connection states, so that the atomizer can adopt different working modes according to the different cigarette cartridges 20. It should be understood that the comparison and judgment operation of the above-mentioned controller is performed when the cigarette cartridge 20 is detachably fixed to the cigarette rod 10 to avoid damage to non-matching cigarette cartridges. Moreover, compared with the prior art using a chip and a data interface, the electronic cigarette 100 of the present invention uses two electrical contact devices, which can greatly reduce the recognition cost, simplify the process, reduce the hardware cost of the cartridge 20, and can also obtain different atomization effects for different cartridges 20.
[0025] Specifically, the number of the first electrical contacts 11A is a, the number of the second electrical contacts 21A is b, a and b are natural numbers, and the number N of the preset connection states satisfies: N≤2 a -1, specifically, the number N of preset connection states is the number of combinations that can be formed by all first electrical contacts 11A: According to the formula: And because Corresponding to the situation that none of the first electrical contacts 11A is in contact with the second electrical contacts 21A, this situation needs to be excluded, therefore: And a and b satisfy: 0<b≤a, a≥1. For example, when a is 2, the preset connection state includes three states: each single first electrical contact 11A is in contact with the corresponding second electrical contact 21A and two first electrical contacts 11A are in contact with the corresponding second electrical contacts 21A at the same time, that is, the maximum number of preset connection states N=2 2-1=3, and so on. In addition, when a=1, the number of preset connection states is 1. At this time, the first electrical contact 11A can be set at a specific position of the first electrical contact device 11 to match the cigarette cartridge 20 with the corresponding second electrical contact 21A. However, in this case, there are too few preset connection states, resulting in too few cigarette cartridges 20 that can be identified and matched. Therefore, it is preferred that a is set to a larger number to achieve the identification of multiple cigarette cartridges 20 that can match the cigarette rod 10 and then determine the matching situation. The comparison module determines the matching situation of the cigarette cartridge 20 and the cigarette rod 10 based on: when the comparison module compares the actual connection state with multiple preset connection states, when the actual connection state is one of the N preset connection states, the matching situation is matched; when the actual connection state is not any of the N preset connection states, the matching situation is mismatched.
[0026] Furthermore, when the comparison module determines that the matching situation is matched, the control module controls the startup of the atomizer and other normal operations, and when the comparison module determines that the matching situation is not matched, the control module controls the speaker to sound an alarm, for example, to prompt the user to replace the cigarette cartridge 20 or prohibit the electronic cigarette 100 from working normally. Therefore, the electronic cigarette 100 of the present invention has a high degree of intelligent recognition of the cigarette cartridge 20, and is convenient for users to use.
[0027] As a further improvement, the number of first electrical contacts 11A is at least two, and one of the first electrical contacts 11A is used for the comparison module to judge the authenticity of the atomizer. That is to say, one of the second electrical contacts 21A of any type of matching cigarette cartridge 20 must be in contact with one of the first electrical contacts 11A. The detection module can first detect the contact through the current value, etc. Only when the detection result meets the matching condition, the contact condition of other first electrical contacts 11A is detected. Therefore, the recognition efficiency of the electronic cigarette 100 is high, and the damage of the cigarette rod 10 by the counterfeit cigarette cartridge 20 is effectively prevented.
[0028] Further, when the matching condition is matched, the comparison module compares the first actual connection condition between one of the first electrical contacts 11A and the second electrical contact 21A and the second actual connection condition between at least one other first contact and the corresponding second electrical contact 21A with a plurality of preset connection states, and determines the authenticity of the atomizer and the working mode of the atomizer according to the comparison results. In this way, the electronic cigarette 100 realizes effective identification of the authenticity and type of the atomizer and obtains a targeted atomization effect.
[0029] Preferably, the working mode of the above-mentioned atomizer includes one or more of heating time, heating temperature and heating frequency. For example, after the controller identifies the cigarette cartridge 20, the different flavors of the cigarette oil set in different cigarette cartridges 20 are baked by the atomizer using different heating curves, so that the taste can reach the most ideal state. For example: the mint flavor with a strong icy feeling requires a longer baking time from low to high, and the power of the heating wire cannot be very large at the beginning, and it needs to increase over a period of time. For example, for mango flavor, it is necessary to bake at high power from the beginning, so that the amount of smoke generated can emit a strong mango flavor. Therefore, the electronic cigarette 100 of the present invention can obtain corresponding atomization effects for different cigarette cartridges 20.
[0030] Preferably, the first electrical contact device 11 is a circuit board with a spring-pin type first electrical contact, and the second electrical contact device 21 is an FPC. Since the second electrical contact device 21 adopts an FPC, it is easier to set a plurality of second electrical contacts 21A with different spatial positions on the FPC, and the FPC has low cost and is easy to install. In addition, the spring-pin type first electrical contact is set on the circuit board, which can ensure good contact between the first electrical contact 11A and the second electrical contact 21A.
[0031] Preferably, a positioning hole 21B is provided in the middle of the FPC, a clamping column 12 matching the positioning hole 21B is provided on the cigarette rod 10, the first electrical contact 11A is provided on the periphery of the clamping column 12, and the second electrical contact 21A is provided on the periphery of the positioning hole 21B. Therefore, the FPC can be well positioned by the clamping column 12, and a large space is provided on the periphery of the clamping column 12 and the positioning hole 21B to respectively set the first electrical contact 11A and the second electrical contact 21A, which can ensure good contact of each contact on the basis of good positioning.
[0032] Preferably, a groove (not shown) is provided on the FPC, and a protrusion (not shown) matched with the groove is provided on the circuit board. In this way, through the structural design, it is possible to avoid the combination of the unmatched cigarette rod 10 and the cigarette cartridge 20, thereby reducing the comparison operation of the comparison module for the unmatched situation, saving time, and further improving the recognition efficiency of the electronic cigarette 100 in identifying the cigarette cartridge 20.
[0033] Preferably, the opposite surfaces of the cigarette rod 10 and the cigarette cartridge 20 for detachable fixation are respectively provided with a recess 13 and a protrusion 22 with a substantially elliptical cross section, and the recess 13 is used to accommodate the FPC therein. Therefore, when the cigarette rod 10 and the cigarette cartridge 20 are matched and detachably fixed, the FPC is accommodated in the recess 13 to prevent external impact forces from directly acting on the FPC, and by setting the recess 13 and the protrusion 22 to have a substantially elliptical cross section, the identification of the cigarette rod 10 and the cigarette cartridge 20 that can match each other is increased.
[0034] Additionally, the cigarette rod 10 also includes a display device electrically connected to the battery, the display device may be a liquid crystal display screen, the controller includes an identification module, the identification module obtains identification information of the cigarette cartridge 20 according to the comparison result corresponding to the cigarette cartridge 20 and the cigarette rod 10 being matched, the identification information may be the type and content of the e-liquid, and the control module controls the display device to display the identification information. Therefore, the user can clearly know the information of the e-liquid in the cigarette cartridge 20 that is identified and matches the cigarette rod 10, which improves the convenience of use for the user.
[0035] Additionally, the controller includes a statistical module, which counts the identification information and calculates the statistical information, and the control module controls the display device to display the statistical information. Therefore, when the above identification information is the type and content of the e-liquid, the user can understand the frequency and total amount of a certain e-liquid used, which is conducive to the user's smoking control and smoking cessation.
[0036] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
