Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smoking articles, in particular to an atomizing device. Background Art
[0002] There are two main methods for detecting cigarette insertion in heat-not-burn tobacco products on the market: one method uses electromagnetic induction effect as a detection method, with a sensing circuit and a field generator in the tobacco product, and a magnetic metal sheet in the cigarette. When the cigarette is inserted or removed, the magnetic metal sheet generates eddy currents in the changing magnetic field, and the system detects the current current. The system determines whether the cigarette has been inserted or removed based on the current, and then determines whether to turn on the heating tube. This method requires the implantation of a metal sheet in the cigarette, which increases the cost of the cigarette, and the sensing circuit and field generator occupy a large space. The second method is to use a micro switch to detect whether the cigarette is inserted. Specifically, a micro switch is placed near the cigarette insertion port of the tobacco product. When the cigarette is inserted / removed, the micro switch is opened or closed, and the system determines whether the cigarette is inserted / removed based on the switch signal. In this method, the micro switch can only determine whether an object has been inserted or removed, but cannot accurately determine whether it is a cigarette, which can easily lead to misjudgment.

[0033] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.
[0034] The utility model proposes an atomizing device, such as Figure 1 As shown, the atomization device includes: a shell, a signal detection component, a controller and a heater 202; a receiving chamber 201 is formed in the shell, and the receiving chamber 201 is used to receive the part to be heated; the heater 202 is used to heat the part to be heated; the signal detection component includes a capacitance detector 204 and a photoelectric detector 203, and the signal detection component is arranged corresponding to the receiving chamber 201 to obtain the capacitance signal and the photoelectric signal of the receiving chamber 201; the controller is communicated with the signal detection component and the heater respectively.
[0035] The signal detection component is arranged corresponding to the receiving chamber 201 to obtain the capacitance signal and the photoelectric signal of the receiving chamber 201, including that the receiving chamber includes an entrance end and a bottom end, and the entrance end is used to insert the cigarette; the signal detection component is arranged at the entrance end of the receiving chamber (the specific connection method can be mechanical connection, bonding and welding, etc.).
[0036] The capacitance detector 204 and the photoelectric detector 203 in the signal detection component are both arranged at the entrance end of the receiving chamber. Preferably, the capacitance detector 204 and the photoelectric detector 203 are staggered up and down along the insertion direction of the receiving chamber, and the photoelectric detector 203 can be located at the upper end of the capacitance detector 204 (near the entrance end of the receiving chamber, specifically Figure 1 This position setting can reduce the interference of the deformation of the capacitance detector 204 on the photoelectric detector 203, and improve the accuracy of the photoelectric detector 203.
[0037] Specifically, the signal detection component includes a flexible circuit board, the capacitance detector 204 is arranged on the flexible circuit board, and the flexible circuit board surrounds the receiving chamber 201. Figure 2 and Figure 3 As shown, the capacitance detector 204 is provided with two capacitance poles, the two capacitance poles are arranged opposite to each other, and the capacitance detector is arranged outside the container. Preferably, the outer wall of the container is provided with a bracket, and the capacitance detector 204 is surrounded and attached to the bracket to form a capacitor. When the heated part such as the cigarette 100 is inserted and removed, the flexible circuit board expands and deforms, and the internal medium of the capacitor formed by the capacitor FPC changes, thereby causing the capacitance value to change. By detecting the capacitance value, the action of inserting and removing the cigarette 100 can be identified.
[0038] According to a specific implementation, the signal detection component is arranged corresponding to the receiving chamber 201 to obtain the capacitance signal and the photoelectric signal of the receiving chamber 201, including that the signal detection component obtains the infrared signal of the receiving chamber 201, and determines whether there is a detection object in the receiving chamber 201 according to the infrared signal, and then the signal detection component obtains the capacitance signal of the receiving chamber 201, and determines whether there is a detection object inserted in the receiving chamber 201 according to the capacitance signal.
[0039] Alternatively, the signal detection component obtains the capacitance signal of the receiving chamber 201, and determines whether a detection object is inserted into the receiving chamber 201 based on the capacitance signal, and then the signal detection component obtains the infrared signal of the receiving chamber 201, and determines whether a detection object is in the receiving chamber 201 based on the infrared signal.
[0040] Preferably, the signal detection component obtains the capacitance signal and infrared signal of the storage chamber 201, and determines whether the capacitance signal meets the first capacitance threshold range and / or the first capacitance threshold range; if the capacitance signal meets the first capacitance threshold range and the infrared signal meets the first infrared threshold range, then a detection object is inserted into the storage chamber 201; if the capacitance signal meets the second capacitance threshold range and the infrared signal meets the second infrared threshold range, then a detection object is pulled out of the storage chamber 201; the signal processor determines whether there is a detection object in the storage chamber 201 according to the insertion and removal of the detection object. A capacitance detector 204 (flexible circuit board) is wrapped at the cigarette insertion port of the storage chamber 201. When the cigarette 100 is inserted or removed, the capacitance value of the capacitance detection circuit on the capacitance detector 204 changes to a specific value, thereby determining whether the cigarette 100 is inserted / removed. Because the capacitance values collected by the capacitance detector 204 are different when the cigarette 100 and the cleaning brush are inserted, the cigarette 100 and the cleaning tool are distinguished, thereby making the use of the atomization device safer. Moreover, the capacitance detection method of the present invention does not require the implantation of metal sheets in the cigarette 100, which not only reduces the cost of the atomization device, but also reduces the space occupied by it.
[0041] Since the change of airflow or other factors during smoking will cause the change of capacitance value to be similar to the change of capacitance value when the cigarette 100 is plugged in and out, which may lead to the misjudgment of plugging in and out of cigarettes, the utility model adds infrared detection. By utilizing the shielding of infrared rays when the cigarette 100 is plugged in and out, it is judged whether the cigarette 100 is inserted or pulled out. By combining the two methods, it is possible to accurately judge whether the cigarette 100 has been inserted and confirm whether the inserted cigarette 100 is a cigarette 100.
[0042] Specifically, a groove is provided on the wall of the receiving chamber 201, and the photoelectric detector 203 is at least partially arranged in the groove. The photoelectric detector 203 includes an infrared transmitter and an infrared receiver; the infrared transmitter and the infrared receiver are arranged relatively to each other, and are used to place the infrared transmitter and the infrared receiver respectively. Preferably, an infrared transmitter and an infrared receiver are wrapped at the cigarette insertion port of the receiving chamber 201. When the cigarette 100 is inserted, the cigarette 100 is blocked between the infrared transmitter and the infrared receiver, thereby compositely confirming the insertion status of the cigarette 100, and further improving the reliability of the detection of the plug-in status of the cigarette 100. The capacitive detector 204 and the photoelectric detector 203 are integrated into the same flexible circuit board.
[0043] The controller is also provided with a signal processor for determining whether there is a detection object in the containing chamber 201 according to the capacitance signal and the photoelectric signal, and judging whether the detection object is a cigarette 100 according to the photoelectric signal.
[0044] The signal processor is provided with a judgement device for judging whether the capacitance signal satisfies the first capacitance threshold range and / or the first infrared threshold range; if the capacitance signal satisfies the first capacitance threshold range and the infrared signal satisfies the first infrared threshold range, a detection object is inserted into the receiving chamber 201; if the capacitance signal satisfies the second capacitance threshold range and the infrared signal satisfies the second infrared threshold range, a detection object is pulled out of the receiving chamber 201; the signal processor determines whether there is a detection object in the receiving chamber 201 according to the actions of inserting and pulling out the detection object.
[0045] The receiving chamber 201 includes an inlet end and a bottom end, wherein the inlet end is used to insert the cigarette 100; the heater 202 is located at the bottom end and is used to heat the inserted cigarette 100. The receiving chamber 201 is an expandable and contractible structure and is used to clamp the cigarette 100. The heater 202 is spaced a certain distance from the signal detection component to reduce the interference of the temperature change of the heating coil or the heater 202 on the signal detection component and improve the accuracy of signal acquisition.
[0046] The atomizing device of the utility model comprises: a housing, a signal detection component, a controller and a heater; a receiving chamber 201 is formed in the housing, and the receiving chamber 201 is used to receive the heated component; the heater is used to heat the heated component; the signal detection component comprises a capacitance detector 204 and a photoelectric detector 203, and the signal detection component is arranged corresponding to the receiving chamber 201 to obtain the capacitance signal and the photoelectric signal of the receiving chamber 201; the controller is respectively connected to the signal detection component and the heater for communication. The utility model can accurately determine whether the cigarette 100 has been inserted, and is more intelligent, convenient and safe to use.
