[0047] The following is combined with Figure 1-4 The present invention is further described.

[0048] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0049] Reference Figure 1 and Figure 2The present invention provides a portable hookah temperature control method, when the water smoke aerosol is filled into the portable hookah, the device is started, which includes the following steps.

[0050] Step S1: preheating. In this step, the water vapor aerosol is heated to a first temperature by controlling the input power of the heating element to be a first input power and keeping the input power constant. The first input power is recorded as P1, and the duration of preheating is a first duration.

[0051] Step S2: The heating is paused, and the water vapor aerosol is controlled to cool down to a third temperature.

[0052] Step S3: In the working stage, the water mist aerosol is heated to a second temperature by controlling the input power of the heating element; and the temperature of the water mist aerosol is controlled to be maintained within the range of the second temperature and the third temperature for a second time period.

[0053] The temperature of the water vapor aerosol detected in the present invention refers to the temperature of the surface of the water vapor aerosol detected.

[0054] In the preheating stage, the first power should be as large as possible, and a larger power is used to heat the water aerosol. Since the input power of the heating element is large enough and the heat generated is sufficient, the water aerosol can absorb more heat in a short time and be fully heated. After starting to heat the water aerosol, the temperature of the water aerosol gradually increases, but it is not suitable to draw in the preheating stage because the water aerosol has not absorbed enough heat. It takes some time for the heat to be transferred from the periphery of the water aerosol to the center of the water aerosol. Since heat loss is inevitable during the heat transfer process, by inputting a larger first input power, the surface of the water aerosol can have a surface temperature higher than the working temperature, so as to ensure that the temperature transferred to the center of the water aerosol can also reach the working temperature, so as to ensure that the water aerosol can be fully atomized.

[0055] The present invention selects metal or alloy with extremely small temperature coefficient as the heating element, so that the resistance of the heating element is not affected by temperature change, and then reasonably selects the effective value of the voltage across the heating element to keep it constant under the real-time control of the processor, so that the input power of the heating element is kept constant during the preheating stage. And the selection of a heating element with a small resistance value makes it possible to achieve a higher input power under the same input voltage, so as to realize a stable and fast preheating stage.

[0056] In step S1, specifically, the device starts preheating, and the temperature detection unit measures the temperature of the heating device in real time. When the temperature reaches the first temperature, the preheating ends, wherein the first time length is the difference between the start and end time of the preheating. In this embodiment, the first time length is 3 minutes to 6 minutes, so that the atomization of the water mist atomizer is more complete and more smoke can be generated.

[0057] Further, in step S2, the water aerosol is controlled to cool down to a third temperature, and the input power provided to the heating element is set to the third input power, so as to cool down the water aerosol, wherein the third input power is P3, and in this embodiment, P3=0W. If the water aerosol is always kept at a high temperature, too much smoke will be generated, and the temperature of the smoke is high, and the user experience is not good. The purpose of step S2 is to appropriately reduce the temperature of the water aerosol, and set P3=0W, that is, completely stop heating the water aerosol, while reducing heat loss, the cooling process of the water aerosol can be accelerated; and in this process, the overall temperature of the water aerosol can be made more uniform, so that the subsequent aerosol has a better taste.

[0058] Stop heating the water mist aerosol. When the temperature drops to the third temperature, further enter the first process, wherein the input power provided by the heating element is set to the second input power to heat the water mist aerosol. The second input power is recorded as P2.

[0059] At the same time, the temperature detection unit inside the device detects the temperature of the water mist aerosol in real time. When the temperature reaches the second temperature, it enters the second process, in which the input power provided by the heating element is set to be the fourth input power, and the fourth input power is P4.

[0060] The first process and the second process are entered alternately, and maintained for the second time period.

[0061] The temperature range formed by the second temperature and the third temperature is appropriately lower than the first temperature, which can improve the taste and make the amount of smoke generated more suitable for users to inhale. In this embodiment, P1>P2≥20W, P4=0W is satisfied.

[0062] Furthermore, the second duration of the alternation between the first process and the second process is recorded as TIME2, which is usually a program setting value, and the purpose is to completely stop heating after the water vapor aerosol is consumed. In this embodiment, TIME2≥10min.

[0063] The input power P4 of the second process is set to 0 W, that is, the second process completely stops heating the aerosol, which can effectively reduce the power loss.

[0064] Since the use time of portable hookah is generally long, usually more than 10 minutes, the device needs to maintain the working temperature during this process, and the power consumption will be relatively large. The working stage of the present invention adopts the form of alternating the first process and the second process, that is, the form of interval heating, so that the average temperature of the water smoke atomizer in the working stage is always kept near the working temperature, while ensuring its effective atomization, reducing power consumption, making the battery life longer, which is conducive to improving the user experience. Among them, the working temperature is the optimal atomization temperature of the water smoke atomizer.

[0065] Furthermore, the first temperature is recorded as T1, the second temperature is recorded as T2, and the third temperature is recorded as T3, wherein: 210℃≤T1≤240℃, 150℃<T3<T2<210℃, the first temperature is greater than the average temperature of the water vapor atomizer in the working stage (i.e., the average of the second temperature and the third temperature), and the difference between the two is the temperature increment set for preheating. The purpose of setting the temperature increment is to allow the water vapor atomizer to absorb sufficient heat during the preheating stage to ensure that it can be fully atomized and have a better taste. For most water vapor atomizers, they can be fully preheated in the temperature range of 210℃-240℃ to produce a large amount of smoke; in the temperature range of 150℃-210℃, they can produce a proper amount of smoke with a suitable temperature, which is conducive to improving the user experience.

[0066] It should be noted that the values ​​of the above parameters can be adjusted appropriately for different types of water vapor aerosols and different inhalation requirements of users.

[0067] Reference Figures 1 to 4 The present invention also provides a portable hookah temperature control system for executing the above-mentioned hookah aerosol control method, which comprises:

[0068] An MCU control unit 1, configured to run instructions to execute the control method of the portable hookah according to any one of claims 1 to 7;

[0069] The NTC temperature detection unit 2 is used to detect the temperature of the water smoke aerosol in real time to feed back the temperature signal to the MCU control unit 1;

[0070] Controlling the heating unit 3 to provide corresponding input power to the heating element;

[0071] Switch unit 4, used to start or stop the device;

[0072] The MCU control unit 1 adjusts the instruction in real time according to the temperature detected by the NTC temperature detection unit 2 to control the temperature within a set range.

[0073] Furthermore, the portable hookah temperature control system of the present invention comprises the following operating steps:

[0074] (1) After the user presses a button, a trigger switch signal is transmitted to the MCU control unit 1. The MCU control unit 1 detects that the button is pressed for a set time of 2 seconds and enters the heating mode;

[0075] (2) After entering the heating mode, the MCU control module first performs an operation test, and first detects whether the device is in an abnormal state such as short circuit, low voltage, open circuit, etc. If an abnormality is detected, the heating is stopped;

[0076] (3) If the test is normal, the heating function is started, the corresponding input power is turned on to the heating element, and the heating is performed at full power, and a fast and high-temperature preheating stage is performed;

[0077] (4) During the heating process, the temperature of the water vapor is detected by the NTC temperature detection unit 2. When the temperature reaches a predetermined high temperature, the heating is suspended;

[0078] (5) After stopping heating, the temperature will drop. When the temperature drops to a predetermined lower limit temperature, the MCU control unit 1 runs the working stage instruction, enters the first process, starts the heating function, and controls the heating element to continue heating;

[0079] (6) At the same time, the NTC temperature detection unit 2 performs real-time temperature detection. When a predetermined upper limit temperature is detected, the second process is entered, and the MCU control unit 1 controls the heating element to suspend heating;

[0080] (7) During the working phase, the first process and the second process are cycled until the set working time is reached, and the MCU control module controls the device to stop working;

[0081] (8) During the heating process, operation detection is carried out simultaneously. If the equipment has an abnormality (such as shutdown action, low battery, etc.), the heating is stopped.

[0082] Specifically, the operation and implementation process are as follows:

[0083] When the portable hookah is turned off, the user long presses the hardware button of the switch unit 4, and the switch unit 4 triggers the switch signal to be transmitted to the MCU control unit 1. The MCU control unit 1 detects that the time of pressing the hardware button reaches the set time of 2s, and then enters the heating mode;

[0084] After the device enters the heating mode, the MCU control module first detects whether the device is abnormal, that is, whether there is an abnormal state such as short circuit, low voltage, open circuit, etc. If an abnormal situation is detected, the heating is stopped;

[0085] If the detection is normal, the heating function is started, the preheating instruction is executed, the first input power is provided to the heating element, and preheating is performed at full power;

[0086] During the heating process, the NTC temperature detection unit 2 detects the temperature of the water smoke aerosol in real time. When it is detected that the temperature reaches a predetermined high temperature, a first temperature signal is sent to the MCU control unit 1. The MCU control unit 1 executes a heating pause instruction to control the heating element to pause heating.

[0087] After the heating is stopped, the temperature of the water smoke aerosol will drop. During this process, the NTC temperature detection unit 2 continues to detect the temperature. When the temperature reaches the predetermined lower limit temperature, the lower limit temperature signal is sent to the MCU control unit 1. The MCU control unit 1 runs the first process instruction of the working stage and provides the second input power to the heating element for heating.

[0088] At the same time, the NTC temperature detection unit 2 continues to detect the temperature. When the temperature reaches the predetermined lower limit temperature, the upper limit temperature signal is sent to the MCU control unit 1. Then the MCU control unit 1 runs the second process instruction of the working stage to control the heating element to stop heating.

[0089] In the working stage, the first process instruction and the second process instruction are executed in a loop until the preset working time is reached, and the MCU control unit 1 controls the heating element to stop heating.

[0090] The average of the predetermined upper limit temperature and the predetermined lower limit temperature is the optimal working temperature of the water aerosol atomizer. In this embodiment, the optimal working temperature of the water aerosol atomizer is 180°C. The predetermined upper limit temperature is set to 170°C and the predetermined upper limit temperature is set to 190°C. The first process instruction and the second process instruction are executed cyclically, so that the average temperature of the water aerosol atomizer can be maintained at 180°C. Compared with maintaining a constant input power at a constant temperature of 180°C during the working stage, the heating time is effectively reduced, so that it can have a good atomization effect, while reducing the power consumption during the working process, so that the battery life is longer.

[0091] Based on the above portable hookah temperature control method and temperature control system, the present invention also provides:

[0093] Furthermore, the NTC temperature detection unit 2 can be arranged in the accommodating chamber of the material barrel, so as to more accurately test the real-time temperature of the water mist aerosol.

[0094] Furthermore, in order to improve the heating efficiency of the water mist aerosol and reduce heat loss, a thermal insulation material may be provided around the outer periphery of the containing barrel to reduce heat dissipation.
