[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0025] like Figs. 1 to 3 As shown, this invention provides an embodiment of a device for acquiring smoking habit data. This device comprises a housing 1, a cigarette holder 2, a filter core 3, a honeycomb-shaped ceramic heating element 4, a heating control module 5, a main control module 6, a lithium battery 7, an intermediate pipe 8, filter cotton 9, a connector 10, and a mouthpiece 11. The housing 1, cigarette holder 2, filter core 3, intermediate pipe 8, filter cotton 9, connector 10, and mouthpiece 11 constitute the main body of the smoking device, but the structure of the main body is not limited to this.
[0026] The heating control module 5 includes circuit modules such as a timing module 501, a voltage control module 502, and a current detection module 503. The ceramic heating element 4 forms the main body of the heating circuit 402 and provides a multi-hole channel 401. The heating circuit 402 is led out through leads 403. The ceramic heating element 4 is a PTC (positive temperature coefficient) device; its internal resistance increases as the temperature rises.
[0027] The voltage control module 502 applies a constant voltage to the heating circuit 402. After the ceramic heating element 4 is powered on, it heats up. When the ceramic heating element 4 heats up, the internal resistance of the heating circuit 402 increases, the current decreases, and the heating rate slows down. Finally, the ceramic heating element 4 reaches thermal equilibrium at a certain temperature.
[0028] When the voltage control module 502 applies different constant voltages to the ceramic heating element, the ceramic heating element will establish thermal equilibrium at different operating temperatures. Based on this characteristic, a correspondence between operating current and operating temperature is established.
[0029] When the heating circuit is operating, the operating current of the ceramic heating element can be detected in real time through the current detection module. Preferably, the current detection module can detect the current through a sampling resistor connected in series in the heating circuit.
[0030] Timing module 501 can be used for standby or shutdown control, such as when the working current is detected to be long-term unchanged (change less than the set threshold), the main control module 6 enters standby state, closes the heating control module 5, and waits for the next trigger. The specific trigger mode can be triggered by the air flow pressure generated by suction or key switch trigger, etc.
[0031] In order to collect and process data, in addition to setting microprocessor 601, power management system, power supply system on the main control module 6, wireless connection module 602, storage unit 603, key 604, and vibration motor 605, LED indicator 606 and other prompting devices are also set. The device can have a smoking function, and the mode can be switched by the key to switch the working mode to the data collection mode. In the data collection mode, the heating of the ceramic heating element 4 is mainly used for data collection, and the temperature in the thermal equilibrium state is between 50℃ and 80℃, which is obviously higher than the ambient temperature, and will not make the smoking body feel hot in the data collection mode. Preferably, the temperature in the thermal equilibrium state is between 50℃ and 60℃.
[0032] The collected smoking data is stored in the storage unit 603 to form a data set with time mark, and is connected with smart terminal devices such as mobile phones and tablets through the wireless connection module 602, and is calculated and displayed on the smart terminal devices. For example, the relationship curve of working current and time, the relationship curve of smoking volume and time, the smoking frequency and the peak value of smoking intensity can be displayed.
[0033] Preferably, the wireless connection module 602 is a Bluetooth module, which has the characteristics of small size and convenient connection.
[0034] Preferably, the storage unit 603 is a Flash memory, which has the characteristics of small volume, large capacity and fast data read-write speed.
[0035] Preferably, the main control module 6 is built-in with an algorithm, which establishes the functional relationship between the working current change and the temperature change in unit time, and the functional relationship between the temperature change and the smoke flow in unit time. The calculation of smoke flow, smoking frequency and peak value of smoking intensity can be directly completed on the device, and prompt information such as prompting that the amount of smoking has exceeded the standard can be directly given.
[0036] The heating wire of the ceramic heating element 4 has PTC characteristics, and the heating loop adopts constant voltage power supply. When the thermal equilibrium is reached, the temperature of the ceramic heating element will stabilize at a certain temperature. In this application, the thermal equilibrium temperature of the ceramic heating element can be set between 50℃ and 60℃ by adjusting the device parameters of the heating loop.
[0037] Through research and invention, it is found that the temperature of the smoke formed after the cigarette filter and the filter core in the state of being ignited and smoked will tend to the ambient temperature.
[0038] When smoking, the smoke passes through the honeycomb ceramic heating element 4. Because the temperature of the inhaled smoke is lower than the thermal equilibrium temperature of the ceramic heating element, the ceramic heating element cools down, and thus the heating circuit needs to reestablish thermal equilibrium. The greater the suction pressure and the greater the volume of a single puff, the greater the temperature drop of the ceramic heating element. Experiments have shown that when the thermal equilibrium temperature of the ceramic heating element is 58℃ and the volume of a single puff is about 60ml (3s of 20ml / s puffing action), the temperature of the ceramic heating element can be reduced by about 10℃.
[0039] To record the smoking habit data, the working current can be periodically detected to obtain a working current-time curve, and the time of thermal equilibrium reestablishment each time can be recorded. Then, data analysis can be performed on the working current-time curve to obtain smoking data such as puffing frequency, total puffing volume, average duration of a single puff, average volume of a single puff, and puffing intensity peak value.
[0040] The smoking habit data acquisition device of the present application can obtain a working current-time curve of the ceramic heating element during puffing by setting the thermal equilibrium temperature of the ceramic heating element and periodically collecting the working current of the ceramic heating element, thereby providing quantitative data analysis for smoking behavior analysis.
[0041] The present embodiment provides a preferred embodiment of the smoking habit data acquisition device, in which the ceramic heating element 4 is a honeycomb ceramic, and the intermediate pipe 8 is made of ceramic. The cigarette holder 2, the connecting piece 10, and the shell 1 are detachably connected, such as by threaded connection or plug-in connection, to facilitate replacement of the filter core 3 and the filter cotton 9 and other filter materials to remove the tar and volatile substances left after tobacco burning.
[0042] At the same time, the shell 1, the cigarette holder 2, the connecting piece 10, the ceramic heating element 4, and the intermediate pipe 8 are tightly connected in the axial direction, and the smoke after the cigarette is lit directly flows out through the passage composed of the filter core 3, the ceramic heating element 4, the intermediate pipe 8, the filter cotton 9, and the mouthpiece 11, and the smoke cannot leak out of the passage to affect the circuit board and the battery and other components. After the filter core 3 and the filter cotton 9 are removed, the intermediate honeycomb ceramic heating element 4 is tightly connected with the intermediate pipe 8, and can be directly washed with water to remove the tar and volatile substances left after tobacco burning.
[0043] The present embodiment provides a preferred example. In specific applications, the filter core 3 and the filter cotton 8 can both be filter cores or filter cottons.
[0044] In an embodiment of the present application, honeycomb ceramic and ceramic intermediate pipeline are adopted. The ceramic is high density and almost has no porosity, so that the substances in the smoke cannot penetrate into the ceramic and cannot leave pollution and odor on the surface. After the tobacco combustion flue gas is filtered by the filter core, part of the tar and volatile substances will remain on the honeycomb ceramic heating body. The heating body can easily take away these residues under the working heating state and normal smoking, and can also be cleaned and maintained by normal flushing without affecting the ceramic device.
[0045] Although the present application has been particularly shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details can be made therein without departing from the spirit and scope of the application as defined by the appended claims.
