Problems solved by technology

[0005] For example, in the portable capsule coffee machine disclosed in Chinese patent CN201310345121.5, its heating device is a PTC heating chip. It can be seen from the contents and accompanying drawings that the PTC heating chip is located at the bottom outside the water tank for safety, so its structure The PTC heater is separated from the water, which will reduce the heat conduction efficiency and increase the power consumption. At the same time, the internal ambient temperature of the PTC heater will rise sharply, and its heat dissipation capacity is poor, which will cause the components to operate at high temperatures. Not working under corrupted settings
[0006] For example, a portable coffee machine disclosed in Chinese patent CN201810908128.6 has a structure similar to that of the above-mentioned patent, and the heating assembly is also placed on the bottom outside the water tank, so it also has the same disadvantages
[0007] In addition, a portable coffee machine with a heating device will also face a problem, that is, according to the principle of thermal expansion and contraction, the pressure in the cup body containing water will rise during the heating process, and the excessive pressure will have a negative impact on the coffee machine itself. cause damage, but also pose a potential risk to the user
Moreover, since the water pump needs to form a negative pressure effect in order to obtain a good brewing effect after heating, if the excessive pressure cannot be discharged during heating, it will inevitably affect the use effect of the water pump, resulting in poor brewing effect

Abstract

The invention discloses a portable coffee machine, which comprises a water cup body, a coffee machine main body and a coffee making seat body which are arranged in sequence from top to bottom, whereina control circuit and a power supply device are arranged in the coffee machine main body; a switch is also arranged on the coffee machine; the switch is connected with the control circuit in a control manner; the water cup body comprises a cup seat and a cup main body; a thick film heating assembly is embedded in the cup seat; the thick film heating assembly is electrically connected with the control circuit; a water inlet channel communicated with the coffee machine main body is formed in the thick film heating assembly; the upper surface of the thick film heating assembly is exposed outsideand can be in direct contact with water; an air inlet and a pressure relief hole are formed in the top of the cup main body; a bidirectional air valve is arranged in the air inlet; the bidirectionalair valve covers the pressure relief hole. The portable coffee machine provides a more efficient, energy-saving, quicker and safer heating effect through the thick film heating assembly, and the bidirectional air valve can realize a balance of internal and external air pressures in a water heating process and a water pumping process of a water pump, so that a potential safety hazard is eliminated,and a long-term normal and stable using effect is guaranteed.

Description

technical field [0001] The present invention relates to a coffee machine, especially a portable coffee machine. Background technique [0002] Coffee is one of the most popular beverages in human society. People are pursuing the quality of coffee and the artistic conception of enjoying coffee. The invention and design of coffee tools and utensils are also constantly being refurbished. At present, popular coffee utensils (such as coffee pots, coffee Machines, etc.) have a wide variety of styles, and portable coffee machines are becoming more and more popular among consumers because of their compact structure and easy portability. [0003] Existing coffee machines use high temperature and high pressure to cook coffee to shorten the time, but this type of coffee machine is not compact enough, and it is extremely inconvenient to carry when traveling. It has always been the pursuit of coffee lovers to carry the coffee machine like a power bank. form. To this end, resourceful peo...
