Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-6 , the utility model embodiment includes:

[0028] A steam rod device with automatic temperature sensing is mainly used for coffee machines and steam machines. Its structure includes: a steam rod movable rod 1, a steam Teflon tube group 2, a Teflon tube group sealing ring 3, a steam rod NTC component 4, an NTC sealing ring 5, a steam rod insulation sleeve 6, a steam rod sealing ring 7, an NTC fixed sleeve 8, a steam rod connecting rod 9, and a steam nozzle 10.

[0029] The upper part of the NTC fixing sleeve is movably connected to the steam rod movable rod, and the lower part of the NTC fixing sleeve is movably connected to the steam rod connecting rod. The lower end of the steam rod connecting rod is connected to the steam nozzle.

[0030] Further preferably, the NTC fixing sleeve, the steam rod connecting rod and the steam nozzle are connected by threads.

[0031] Further preferably, the structure of the steam nozzle includes a spray seat 101, a steam inlet hole 103, and a steam outlet hole 102. A plurality of steam inlet holes are arranged in an array on the bottom of the spray seat. A plurality of inclined steam outlet holes are arranged in an array on the bottom of the spray seat. The inclination angle is 10-40°. When multiple steam outlets at special angles emit steam at the same time, the steam will flow around each other, realizing liquid stirring and flipping, making the foam denser and more fusible.

[0032] Further preferably, the steam nozzle and the steam rod connecting rod are made of high-performance special plastic (such as PEEK, PPS, etc.), avoiding the problems of traditional metal rods that easily burn milk due to fast heat conduction and cause drying and difficulty in cleaning.

[0033] The steam rod NTC assembly includes a connecting seat 41, a steam channel 42, a sensor housing 43, and a temperature sensor body 44. The steam channel is arranged in the connecting seat, the steam Teflon tube group passes through the steam rod movable rod, and its lower end extends into the connecting seat and is connected to the steam channel to transport steam. The sensor housing is arranged at the lower part of the connecting seat, and the temperature sensor body is arranged at the bottom of the sensor housing to detect the liquid temperature, wherein the temperature sensor body can adopt a common sensor in this field.

[0034] Further preferably, the sensor housing is a metal hollow rod structure, the top of the sensor housing is sealed with high-temperature resin to prevent water vapor from entering, and a thermistor is embedded inside the sensor housing to automatically sense the liquid temperature. The temperature sensed by the thermistor, on the one hand, when the final liquid position reaches a preset value, will trigger the coffee machine to automatically stop working; on the other hand, the temperature can be monitored in real time so that the coffee machine can control the entry of air according to different temperature values, thereby achieving different foaming rates and degrees of fusion.

[0035] The connecting seat is movably arranged in the NTC fixing sleeve, and a lower supporting block is arranged at the lower part of the NTC fixing sleeve to support the steam rod NTC assembly. An upper limit block 11 is arranged at the lower part of the inner cavity of the movable rod of the steam rod to limit the top position of the connecting seat and prevent the connecting seat from moving up and down.

[0036] Further preferably, a Teflon tube group sealing ring is provided at the connection between the Teflon tube group and the connecting seat / steam channel, a steam rod sealing ring is provided at the connection between the NTC fixing sleeve and the steam rod connecting rod, and an NTC sealing ring is provided between the sensor housing and the connecting seat to complete the sealing and prevent steam leakage.

[0037] Further preferably, the steam Teflon tube assembly is provided with a fixing seat 21 for preventing withdrawal, and the fixing seat is connected to the connecting seat through threads.

[0038] The steam rod insulation sleeve is arranged on the steam rod movable rod, the NTC fixed sleeve and the steam rod connecting rod. A drag handle 61 is arranged on the outer wall of the steam rod insulation sleeve. When using the steam rod, only the setting part needs to be operated. The inner wall array of the steam rod insulation sleeve is arranged with heat dissipation ribs 62. Since the surface temperature of the steam rod increases when high-temperature steam passes through, through cooperation with the steam rod insulation sleeve, on the one hand, the contact area with the steam rod can be reduced, and on the other hand, the internal air circulation can be accelerated to improve the heat dissipation efficiency.

[0039] During assembly, the steam rod movable rod, steam Teflon tube group, and steam rod NTC assembly are assembled and connected, and then the assembly is assembled on the steam rod movable rod, fastened by the NTC fixing sleeve, and then sealed with a sealing ring to complete the base; then the steam rod insulation sleeve, steam rod connecting rod, and steam nozzle are assembled in sequence to assemble as a whole. The steam rod connecting rod and steam nozzle that come into contact with the milk are threadedly matched with the base, which is convenient for disassembly and cleaning, and the steam rod NTC assembly is a whole cavity, without cleaning dead corners, which is conducive to thorough cleaning. When in use, first put the steam nozzle and the lower part of the steam rod connecting rod deep into the milk, and then the steam passes through the steam Teflon tube group, the steam channel, and the conveying channel in the steam rod connecting rod in turn, and finally sprayed out from the steam nozzle to whip the milk or milk foam, and during the whipping process, the temperature sensor detects the temperature of the milk in real time and feeds back to the control system of the coffee machine so that the coffee machine can be adjusted and controlled in real time.

[0040] The beneficial effects of the steam rod device with automatic temperature sensing of the utility model are:

[0041] 1. Simple structure, convenient operation, quick installation and disassembly, easy to clean, and improve food hygiene and safety;

[0042] 2. Reduce the technical difficulty of heating and whipping milk, improve product consistency, and achieve high-quality automatic whipping of milk and milk foam, so as to facilitate the controllable temperature, foaming rate and volume.
