Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically a device for venting residual steam from pipes. Background Technology

[0002] Coffee is one of the world's three major beverages, and making coffee is inseparable from coffee machines. The advent of coffee machines has freed people's hands and allowed them to pursue more coffee flavors. It is a product of the combination of demand and technology, breaking the limitations of instant coffee and greatly expanding the possibilities of coffee consumption. In the process of using coffee machines, people's lives have gradually become richer, their lifestyles have changed significantly, and even a coffee culture has emerged. In particular, making a perfect espresso or cappuccino requires a specialized coffee machine, and cappuccino making requires steam generated by the steam boiler inside the machine. Steam evenly injected into the milk makes it smoother and warms it simultaneously—a double benefit. However, after the steam input stops, some steam can remain in the steam transmission pipes, and the temperature inside the pipes drops rapidly, causing the residual steam to quickly condense into water droplets. These residual steam and water droplets, when they enter freshly made milk, affect the taste of the milk, increasing the difficulty of making a cappuccino and also affecting the taste of the final coffee.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-3 A device for discharging residual steam from a pipeline includes a valve body 6, a valve core 2, a tee 5, a counterweight 1, an elastic limiting element, and a sealing element. One side of the valve body 6 is movably connected to the tee 5, and a detachable connection structure is provided between them. This detachable connection structure is a threaded structure; specifically, the outer circumferential surface of the connecting end of the valve body 6 has an external thread, and the corresponding inner circumferential surface of the connecting end of the tee 5 has an internal thread. A stable connection is achieved through the engagement of the internal and external threads, which also facilitates subsequent disassembly and maintenance. The valve core 2 is movably disposed within the valve body 6, and the axis of the valve core 2 is collinear with the axis of the valve body 6. The valve core 2 is arranged along the axial direction of the valve body 6. This coaxial structure ensures that the valve core 2 is subjected to uniform force during movement, avoiding jamming or displacement, and ensuring the stability of the device operation. The counterweight 1 is connected to the end of the valve core 2, and the counterweight 1 and the end of the valve core 2 are detachably connected by a thread. When different counterweights 1 need to be replaced, disassembly and installation can be completed simply by rotating, making operation convenient. The sealing element is an O-ring 4, which is fitted on the outer circumferential surface of the valve core 2 and contacts the inner wall of the valve body 6. The O-ring 4 is made of heat-resistant rubber material, which can maintain good elasticity and sealing performance in the high-temperature environment of steam.

[0024] In this embodiment, when the tee 5 is filled with steam, the steam exerts upward pressure on the valve core 2. Since the axis of the valve core 2 is collinear with the axis of the valve body 6, the pressure can be evenly applied to the valve core 2, pushing it upward along the axis of the valve body 6. During the upward movement of the valve core 2, the O-ring 4 remains in close contact with the inner wall of the valve body 6. As the valve core 2 moves, when the O-ring 4 reaches a specific position, it simultaneously comes into contact with the upper inner wall of the valve body 6 and the lower stepped surface of the valve core 2, forming a double seal. This effectively prevents steam from leaking from the gap between the valve body 6 and the valve core 2, ensuring that all steam can be delivered to the milk from the outlet of the tee 5, meeting the steam requirements for making cappuccino. At the same time, the counterweight 1 moves upward with the valve core 2, and its gravity exerts a downward pulling force on the valve core 2. When the steam pressure is stable, the valve core 2 can maintain balance under the upward steam pressure and downward gravity, remaining in a specific position to ensure stable steam output.

[0025] Example 2

[0026] Please see Figure 1-3 A device for discharging residual steam from a pipeline includes a valve body 6, a valve core 2, a tee 5, a counterweight 1, an elastic limiting element, and a sealing element. One side of the valve body 6 is movably connected to the tee 5, and the detachable connection structure between them is a snap-fit ​​structure. The connecting end of the valve body 6 has an annular groove, and the corresponding connecting end of the tee 5 has an elastically deformable snap. Quick connection is achieved by snapping the snap into the groove; disassembly is achieved by simply pressing the snap to release it from the groove, making operation simple and efficient. The valve core 2 is movably disposed within the valve body 6, with its axis collinear with the axis of the valve body 6. This structural design prevents frictional interference between the valve core 2 and the inner wall of the valve body 6 during vertical movement, extending the device's service life. The counterweight 1 is connected to the end of the valve core 2, and the connection between the counterweight 1 and the end of the valve core 2 is detachable. The appropriate weight of the counterweight 1 can be selected according to different steam pipeline specifications and usage scenarios. The elastic limiting element is an E-type snap ring 3, which snaps onto the outer circumference of the valve core 2 and forms an axial limiting fit with the valve body 6. The E-type snap ring 3 is made of spring steel and has good elasticity and toughness. An exhaust port is provided on the side wall of the valve body 6, and the position of the exhaust port corresponds to the movement path of the valve core 2. When the valve core 2 moves downward to a certain position, residual steam in the pipeline can be quickly discharged through the exhaust port.

[0027] In this embodiment, when the amount of steam in the tee 5 decreases, the upward pressure of the steam on the valve core 2 gradually decreases. At this time, the gravity of the counterweight 1 plays a dominant role, pushing the valve core 2 downward along the axis of the valve body 6. Since the valve core 2 is coaxially set with the valve body 6, the valve core 2 can move downward smoothly without tilting or jamming. During the downward movement of the valve core 2, the E-type retaining ring 3 moves with the valve core 2. When the E-type retaining ring 3 contacts the limiting step inside the valve body 6, the valve core 2 stops moving, preventing the valve core 2 from moving too far downward and colliding with the tee 5 or blocking the steam passage. At this time, the exhaust port on the side wall of the valve body 6 is fully exposed, and the residual steam in the pipe is quickly discharged to the outside through the exhaust port under the action of pressure difference, thereby preventing the phenomenon of residual steam liquefying into water droplets and entering the milk. In addition, the tee 5 and the valve body 6 are connected by a snap-fit, so when the device needs to be cleaned or repaired, the two can be quickly disassembled to inspect and replace internal components such as the valve core 2 and O-ring 4, which greatly improves maintenance efficiency.
