[0003] The present application relates to the technical field of smoking set, and in particular to an intelligent heating device for hookah and an intelligent heating method. BACKGROUND

[0004] Hookah is also known as nargile or hookah, and traditional hookah relies on hookah charcoal to heat tobacco, which can cause problems such as unstable temperature control, harmful gas emissions (such as carbon monoxide, volatile gases), and over-heating and burning of tobacco, which can affect the flavor of tobacco and produce unpleasant smoke.

[0005] The current electric heating scheme on the market has complex heating structure, unstable temperature control, and is prone to over-heating and burning of tobacco, or the heating temperature is not enough to fully heat the tobacco. In addition, the shape of the electric heating element is not reasonably designed, which cannot uniformly and completely heat the tobacco, and is prone to waste of electric heating wire heat or over-concentration of heating position, and low heat utilization efficiency. SUMMARY

[0006] The present application aims to at least solve one of the technical problems in the related art. To this end, the present application proposes an intelligent heating device for hookah and an intelligent heating method, which can help to solve the above technical problems.

[0007] To achieve the above purpose, the first aspect of the present application proposes an intelligent heating device for hookah, comprising a spiral pipe, a heating assembly, a temperature measuring assembly and a control module; the heating assembly and the temperature measuring assembly are isolated from each other and are arranged in the spiral pipe, and the heating assembly and the temperature measuring assembly are electrically connected with the control module; the spiral pipe is used for heating the airflow passing through it, and the control module is used for controlling the heating assembly according to the real-time temperature information obtained by the temperature measuring assembly, so that the airflow is located in a specific temperature range.

[0008] Compared with the prior art, the present application has the following advantages:

[0009] The intelligent heating device for water pipe greatly increases the heating area by adopting a spiral pipe, continuously measures the temperature of the spiral pipe by using a temperature measuring assembly, and helps the control module to accurately control the heating assembly to maintain the spiral pipe at a preset temperature or temperature range, thereby ensuring stable and efficient heating and temperature maintenance effects on the airflow.

[0010] Further, the heating assembly comprises a resistance wire. The technical effect is that the resistance wire heating is an electric heating method for objects by using the heat energy generated by the Joule effect of current flowing through a conductor, and is the simplest and most efficient heating method based on electricity, which can heat different types of substances with an efficiency of almost 100% and a high working temperature. The controllability and rapid heating characteristics are most convenient for the intelligent control of heating tobacco.

[0011] Further, the heating assembly penetrates the spiral pipe along the length direction of the spiral pipe. The technical effect is that the heat can be uniformly conducted to the entire length dimension range of the spiral pipe, and then the airflow penetrating the winding center of the spiral pipe can be smoothly heated by the spiral bending structure of the spiral pipe.

The technical effect is that the K-type thermocouple has the advantages of high measurement accuracy, wide measurement range, simple structure and low failure rate, and can meet the timely and accurate temperature measurement.

[0013] Further, the temperature measuring probe of the temperature measuring assembly is arranged at the end of the spiral pipe away from the heating assembly. The technical effect is that the temperature measuring assembly and the heating assembly are integrally arranged in the spiral pipe to realize the unity of heating and temperature measurement, and the temperature measuring probe of the temperature measuring assembly is arranged at the end of the pipe to avoid excessive interference between them, prevent the measurement point from being concentrated or close to a position near the heating assembly, and ensure accurate temperature measurement.

[0014] Further, the control module comprises a PID controller. The technical effect is that PID control is proportional-integral-derivative control, and the PID controller as a linear controller has the advantages of simple algorithm, good robustness and high reliability, and can realize rapid and accurate temperature regulation effect.

[0015] Further, an insulating layer is arranged in the spiral pipe, and the heating assembly and the temperature measuring assembly are located in the insulating layer. The technical effect is that the insulating layer serves as an insulator between the heating assembly circuit and the temperature measuring assembly circuit in the spiral pipe, prevents the heating resistance wire from directly contacting the temperature sensor circuit, and ensures the safety and efficiency of the heating system.

[0016] Further, the insulating layer is a ceramic powder insulating layer, which has the advantages of high mechanical strength, high thermal conductivity, good wear resistance, excellent insulation performance in high-temperature and high-frequency environments, stable chemical and physical properties, and good heating performance of the spiral pipe while ensuring insulation between internal components.

The temperature measuring assembly continuously measures the real-time temperature of the spiral pipe; when the real-time temperature of the spiral pipe is lower than the minimum temperature, step 1 is performed; when the real-time temperature of the spiral pipe is equal to or higher than the minimum temperature, step 2 is performed; when the real-time temperature of the spiral pipe is higher than the maximum temperature, step 3 is performed.

[0019] Compared with the prior art, the present application has the following advantages:

[0020] The intelligent heating method for hookah uses the temperature measuring assembly to continuously measure the temperature of the spiral pipe, which helps the control module to accurately control the heating assembly to maintain the spiral pipe at a preset temperature or temperature range, ensuring stable and efficient heating and temperature maintenance of the airflow.

[0021] To achieve the above object, the third aspect of the present application provides an intelligent heating method for hookah, performing a cycle control process until a preset condition is met, and the cycle control process includes:

[0022] Step A: the control module controls the heating assembly to heat the spiral pipe to a preset temperature; Step B: the control module controls the heating assembly to stop heating the spiral pipe. The temperature measuring assembly continuously measures the real-time temperature of the spiral pipe; when the real-time temperature of the spiral pipe is lower than the preset temperature, step A is performed; when the real-time temperature of the spiral pipe is equal to or higher than the preset temperature, step B is performed.

[0023] Compared with the prior art, the present application has the following advantages:

[0024] The intelligent heating method for hookah has the advantages of simple algorithm, good robustness and high reliability, can achieve fast temperature regulation effect, and can achieve very precise temperature control, can keep the heating temperature in the best range, thereby ensuring the quality of the smoke and preventing the tobacco from being heated insufficiently or overheated.
