AI Technical Summary
The flow area of the water heating element in existing beverage machines is fixed at the inlet and outlet, which means that increasing the water flow rate requires increasing the design cost.
A detachable first plug is installed inside the pipe. A first flow channel is set in the middle of the first plug. The flow channel area is smaller than that of the inlet end. The water flow velocity is increased by adjusting the plug. The connection stability is enhanced by combining flexible materials and interference fit.
This increased the water flow velocity and reduced the overall design cost.

Abstract
Description
Technical Field
[0001] This utility model relates to beverage machine accessories, and in particular to a pipe assembly for a beverage machine. Background Technology
[0002] Beverage machines, including coffee machines, generally have a pipe assembly inside that heats water. The pipe assembly includes a water heating element and a pipe. The water heating element has an inlet and an outlet. One end of the pipe is fixedly connected to the inlet, and the other end of the pipe is connected to an external water source and inputs water into the water heating element through the pipe.
[0003] However, the flow area of the inlet and outlet of the existing water heater is fixed. If the flow rate of the water in the water heater is to be increased, the mold must be redesigned to reduce the flow area of the inlet and thus increase the flow rate of the inlet and the overall water flow. This approach undoubtedly increases the overall design cost. Utility Model Content
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pipe assembly for a beverage machine that increases the water flow rate in the water heating body while reducing the overall design cost.
[0005] The technical solution adopted by this utility model to solve the problem is: a pipe assembly for a beverage machine, including a water heating element and a pipe. The water heating element is provided with an inlet end and an outlet end. One end of the pipe is fixedly connected to the inlet end, and the other end of the pipe is used to input an external water source. A first plug is installed inside the pipe, and a first flow channel is provided in the middle of the first plug. The flow area of the first flow channel is smaller than the flow area of the inlet end.
[0006] As a further improvement to the above technical solution, the first plug is detachably connected to the pipeline.
[0007] As a further improvement to the above technical solution, the pipeline is made of a flexible material, and the first plug is interference-fitted with the pipeline.
[0008] As a further improvement to the above technical solution, the first flow channel is cylindrical.
[0009] As a further improvement to the above technical solution, the first flow channel is truncated cone-shaped, and the flow area of the first flow channel gradually decreases from the input end to the output end, with the minimum flow area of the first flow channel being close to the water inlet end.
[0010] As a further improvement to the above technical solution, the pipeline is also equipped with a second plug, and a second flow channel is provided in the middle of the second plug. The flow area of the second flow channel is larger than the flow area of the first flow channel, and the first plug is located between the water inlet end and the second plug.
[0011] As a further improvement to the above technical solution, the pipeline is also equipped with a third plug, and a third flow channel is provided in the middle of the third plug. The flow area of the third flow channel is larger than the flow area of the second flow channel. The first plug, the second plug, and the third plug are arranged adjacent to each other in sequence.
[0012] The beneficial effects of this utility model are: by installing a first plug in the pipe, and setting a first flow channel in the middle of the first plug, the flow area of the first flow channel is smaller than the flow area of the water inlet, thereby increasing the flow rate of water entering the water heating element, and the design cost is low.

[0023] Reference Figures 1 to 4 A piping assembly for a beverage machine includes a water heating element 1 and a pipe 2. The water heating element 1 is provided with an inlet end 11 and an outlet end 12. One end of the pipe 2 is fixedly connected to the inlet end 11, and the other end of the pipe 2 is used to input an external water source. A first plug 3 is installed inside the pipe 2. A first flow channel 31 is provided in the middle of the first plug 3. The flow area of the first flow channel 31 is smaller than the flow area of the inlet end 11. After the water flows in from the other end of the pipe 2, it flows through the first flow channel 31. Due to the reduced flow area of the first flow channel 31, the flow velocity increases, thereby increasing the flow velocity of the water flowing into the water heating element 1, achieving the purpose of increasing the water flow velocity while keeping the design cost low.
[0024] Furthermore, the first plug 3 abuts against the port of the water inlet 11.
[0025] In a preferred embodiment, the first plug 3 is detachably connected to the pipe 2, allowing the user to change the flow rate into the water heating element 1 by replacing plugs with different flow areas.
[0026] In a preferred embodiment, the pipe 2 is made of a flexible material, and the first plug 3 is interference-fitted with the pipe 2 to increase the friction between the first plug 3 and the pipe 2, increase the stability of the connection, and prevent loosening.
[0027] In some embodiments, such as Figure 2As shown, the first flow channel 31 is cylindrical, and the flow areas at both ends of the first flow channel 31 are the same.
[0028] In a preferred embodiment, such as Figure 3 As shown, the first flow channel 31 is truncated cone-shaped, and the flow area of the first flow channel 31 gradually decreases from the input end to the output end. The point where the flow area of the first flow channel 31 is the smallest is close to the water inlet end 11, that is, the output end of the first flow channel 31 is adjacent to the water inlet end 11, so that the water flow velocity gradually increases and the smoothness of the water flow is improved.
[0029] In other embodiments, such as Figure 4 As shown, the pipe 2 is also equipped with a second plug 4. A second flow channel 41 is provided in the middle of the second plug 4. The flow area of the second flow channel 41 is larger than that of the first flow channel 31. The first plug 3 is located between the water inlet 11 and the second plug 4. The water flows through the second plug 4, the first plug 3 and the water inlet 11 in sequence, so that the water flow velocity gradually increases and the smoothness of the water flow is improved.
[0030] Furthermore, in other embodiments, such as Figure 4 As shown, the pipe 2 is also equipped with a third plug 5. A third flow channel 51 is provided in the middle of the third plug 5. The flow area of the third flow channel 51 is larger than that of the second flow channel 41. The first plug 3, the second plug 4, and the third plug 5 are arranged adjacent to each other in sequence, further increasing the water flow velocity and improving the smoothness of the water flow. It should be noted that, following the above-mentioned speed-increasing principle (Venturi effect), a fourth plug, a fifth plug, etc., can also be installed in the pipe 2, which will not be elaborated here.
[0031] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
