Description

Coffee machine capable of controlling temperature Technical Field The utility model relates to a temperature-controllable coffee machine, in particular to a coffee machine which can adjust and stabilize water temperature through a control component so as to improve coffee extraction quality. Background In modern society, people can often see the situation that one cup of coffee is taken on the road, and besides being capable of effectively refreshing, a lot of scientific researches in recent years also show that the risk of getting specific diseases, especially cardiovascular diseases, can be greatly reduced by taking a proper amount of coffee. As the demand for coffee continues to increase, the coffee market grows better and better, and according to the global coffee market report, the coffee market size in year 2030 reaches $1708 billion, and the huge value behind the coffee market is considerable. The coffee brewing machine is used for brewing a cup of delicious coffee, most importantly, the coffee is brewed, along with the development of the times, consumers seek the flavor of the coffee, besides various coffee beans, various brewing modes are derived, so that different types of coffee beans can be matched to brew the coffee with more aromatic flavor, wherein the coffee is brewed by a semi-automatic or fully-automatic machine, and the manual coffee machine is used for brewing the coffee in a large volume, and in the modern society with quite rapid pace, the manual coffee machine still can occupy a place because the brewed coffee is limited by the machine operation flow unlike the machine brewing method, the brewed coffee has more unique characteristics, and the manual brewing can be flexibly adjusted according to personal preference for some coffee makers or coffee lovers, so that the coffee brewing machine is more attractive. The conventional manual coffee machine uses a boiler heating system to provide hot water, and pushes the hot water to a brewing head through water pressure, although the system has a simple structure and low cost, the system still has a big problem that the temperature fine control effect is extremely poor, the water temperature fluctuation is large, especially after multiple times of brewing, the water temperature becomes unstable to influence the quality of extracted coffee, when a user pulls a pull rod to brew, the water temperature does not immediately react with the output of a heating component, a certain time delay exists, and even when the heating component reaches a certain temperature, the water temperature can start to drop, namely the condition that the water temperature falls back occurs, so that the water temperature of the brewing head cannot be constantly maintained in an ideal range, the stability of brewed coffee is influenced, while some operators have the problem that the temperature drop occurs when steam and brewing is reduced through a double boiler system, or the effect of improving the temperature control through a heat exchanger is still unable to be solved according to the environment condition or the existing temperature control technology with high precision. Therefore, how to provide a temperature control system with high precision so that the hot water can be in an ideal temperature range normally, and the parameters can be adjusted at any time according to the needs of the user, so that the brewed coffee is a more aromatic coffee machine is an important direction of current development. Disclosure of utility model The main purpose of the utility model is that the user can keep the water temperature of the coffee machine in a set range through simple operation, and can set different water temperatures according to different demands to ensure the quality of the brewed coffee to be stable, which avoids the problems that the water temperature of the existing coffee machine is greatly fluctuated and cannot be adjusted in a movable temperature control way, so that the water temperature cannot be kept in an optimal temperature range normally, and the brewed coffee has bad taste, however, in order to achieve the purpose and improve the existing defect, the utility model relates to a temperature-controllable coffee machine which comprises a coffee machine body; a brewing head connected with the coffee machine body, wherein a flow passage is arranged in the brewing head; the coffee machine comprises a coffee machine body, a flow passage, a brewing head pull rod, a water tank, a control component, a solenoid valve component, a water pump, a temperature detection component, a heating component, a control component and a control component, wherein the brewing head pull rod is connected with the brewing head and is driven by external force to control the opening and closing of the flow passage, the water tank is arranged in the coffee machine body and is communicated with the flow passage and the water tank, the circulation pipeline comprises a water inlet pipeli
