Description

Technical Field

[0001] This utility model relates to the field of coffee machine auxiliary equipment technology, specifically to an outlet structure of a coffee machine brewing device. Background Technology

[0002] The existing patent, CN203106818U, discloses an outlet structure for a coffee machine brewing device, including a brewing device, a three-way valve, a coffee cup, and a wastewater collection device. The inlet of the three-way valve is connected to the brewing device, and the outlet of the three-way valve is connected to both the coffee cup and the wastewater collection device; all connections are pipeline connections. The beneficial effects of this technical solution are: it effectively discharges the initially brewed coffee containing large bubbles and the coffee residue in the pipeline into the wastewater collection device, greatly improving the quality of the coffee flowing into the coffee cup; at the same time, the structure is simple and easy to use. It cleans the residual coffee in the pipeline by setting a three-way valve at the outlet. Analysis reveals that the liquid used to clean the pipeline originates from inside the coffee machine brewing device, and there is a lack of a collection device for the wastewater after rinsing. The water inside the coffee machine brewing device is used for cleaning, but this water is used for coffee brewing and has limited cleaning capacity. Furthermore, since coffee machines are often placed in clean work environments, there is generally a lack of readily available devices for collecting the cleaning wastewater.

[0003] Therefore, in view of the above-mentioned problems, this technical solution designs an outlet structure for a coffee machine brewing device. Utility Model Content

[0004] The purpose of this invention is to provide an outlet structure for a coffee machine brewing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A coffee maker brewing device outlet structure includes an outlet pipe connected to the bottom of the coffee maker brewing device. The outlet pipe is funnel-shaped with a columnar output end at the bottom. Brewed coffee liquid is discharged outwards along the outlet pipe and the output end for consumption. A connecting sleeve is fitted into the bottom of the output end in a lifting manner. One side of the connecting sleeve is connected to a wastewater collection tank via a flexible hose. Wastewater from rinsing inside the coffee maker brewing device outlet pipe is transferred to the wastewater collection tank for collection via the connecting sleeve and the flexible hose. Simultaneously, a food-grade cleaning agent tank is inserted outwards onto one side wall of the upper part of the coffee maker brewing device outlet pipe. The lower part of the food-grade cleaning agent tank is filled with food-grade cleaning liquid, and the upper part is equipped with a mechanism for manually controlling the flow of the food-grade cleaning liquid into the coffee maker brewing device outlet pipe. The lifting pump mechanism connects the food-grade cleaning agent tank and the wastewater collection tank via a handheld connecting rod. Before use, the food-grade cleaning agent tank is connected longitudinally to the outlet pipe of the coffee machine brewing device via a connecting sleeve. Then, under the action of the lifting pump mechanism, the food-grade cleaning solution inside the tank spreads along the outlet pipe, rinsing away impurities. The solution is then transferred along the connecting sleeve and flexible hose to the wastewater collection tank for convenient cleaning of the outlet pipe and outlet without affecting the normal use of the brewing water. This allows for rapid cleaning of the outlet pipe and outlet, as well as convenient collection of wastewater.

[0007] Compared with the prior art, the beneficial effects of this utility model are: by providing special cleaning solution through an external food-grade cleaning agent container, the use of brewing water inside the coffee machine is avoided, and the cleaning effect is significantly improved.

[0008] Wastewater is diverted into a collection tank via a connecting sleeve and a flexible hose, thus preventing environmental pollution.

[0009] The dual-tank structure is integrated with a handheld connecting rod, and a manual lifting pump mechanism allows for cleaning without electricity. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Please see Figures 1-4A coffee machine brewing device outlet structure includes a coffee machine brewing device outlet pipe 10 connected to the bottom of the coffee machine brewing device. The coffee machine brewing device outlet pipe 10 is configured with a funnel-shaped structure and a columnar output end 11 at the bottom. After brewing, the coffee liquid is discharged outwards for drinking along the coffee machine brewing device outlet pipe 10 and the output end 11. A set of connecting sleeves 12 is fitted into the bottom of the output end 11 in a lifting manner. One side of the connecting sleeves 12 is connected to a wastewater collection tank 15 through a telescopic hose 17. That is, the waste liquid after rinsing inside the coffee machine brewing device outlet pipe 10 is transferred to the wastewater collection tank 15 for collection through the connecting sleeves 12 and the telescopic hose 17. At the same time, a set of food-grade cleaning agent tanks 14 is inserted and connected to the upper side wall of the coffee machine brewing device outlet pipe 10. The lower side of the food-grade cleaning agent tanks 14 is filled with food-grade cleaning liquid, and the upper side is provided with a device for manually controlling the delivery of food-grade cleaning liquid into the coffee machine brewing device outlet pipe 10. The lifting pump mechanism connects the food-grade cleaning agent tank 14 and the wastewater collection tank 15 via a handheld connecting rod 16. Before use, the food-grade cleaning agent tank 14 is connected to the upper part of the coffee machine brewing device's outlet pipe 10 via a longitudinal connection between the connecting sleeve 12 and the output end 11. Then, under the action of the lifting pump mechanism, the food-grade cleaning solution inside the tank 14 diffuses and flows along the coffee machine brewing device's outlet pipe 10, rinsing impurities inside the outlet pipe 10 and output end 11. The solution is then transferred along the connecting sleeve 12 and the telescopic hose 17 to the wastewater collection tank 15 for collection. This allows for convenient cleaning of the coffee machine brewing device's outlet pipe 10 and output end 11 without affecting the normal use of the brewing water. It also enables rapid cleaning of the coffee machine brewing device's outlet pipe 10 and output end 11, and convenient collection of subsequent wastewater.

[0020] A sealing ring 13 is provided around the inner side of the connecting sleeve 12 to ensure the airtightness of the connection between the connecting sleeve 12 and the output end 11. At the same time, when using the wastewater collection tank 15 and the food-grade cleaning agent tank 14, since the rinsing time inside the coffee machine brewing device outlet pipe 10 is short, the user can simply hold the connecting rod 16 and place it on one side of the coffee machine brewing device outlet pipe 10. Meanwhile, the bottom of the wastewater collection tank 15 can be placed on the coffee machine table, and then the user can operate the lifting pump mechanism with the other hand.

[0021] In this embodiment of the invention, the middle side of the hand-held connecting rod 16 is bent outward to facilitate hand-held operation, and the end of the telescopic hose 17 away from the connecting sleeve 12 is inserted and connected to the top of the wastewater collection tank 15 to facilitate the output of waste liquid inside the wastewater collection tank 15.

[0022] A cleaning agent inlet valve 19 is provided on one side of the lower part of the side wall of the food-grade cleaning agent tank 14 for the input of food-grade cleaning liquid. An outlet is provided on the other side, and a connecting pipe is connected to the outside of the outlet. A cleaning agent output connection female valve 20 is installed at the end of the connecting pipe. A cleaning agent output connection male valve 21 is provided on the side wall of the corresponding coffee machine brewing device outlet pipe 10. By controlling the connection between the cleaning agent output connection female valve 20 and the cleaning agent output connection male valve 21, the connection between the food-grade cleaning agent tank 14 and the coffee machine brewing device outlet pipe 10 can be realized. At the same time, the cleaning agent inlet valve 19 is connected to the external connecting valve for the input of external food-grade cleaning liquid.

[0023] Specifically, the lifting pump mechanism includes a piston plate 27 that slides up and down along the inside of the food-grade cleaning agent tank 14. A lifting plate 24 is connected to the top center of the piston plate 27 via a connecting rod 26. The top of the lifting plate 24 is elastically connected to the inner top wall of the food-grade cleaning agent tank 14 via multiple evenly distributed springs 25. Multiple sliders 23 are circumferentially and evenly spaced along the outer wall of the lifting plate 24. The outer ends of the sliders 23 away from the lifting plate 24 are connected to a lifting collar 18 fitted onto the outside of the food-grade cleaning agent tank 14. The sliders 23 correspond to the food-grade cleaning agent... The detergent tank 14 has a lifting slide 22 parallel to the axis of the food-grade detergent tank 14 on its wall. The slider 23 located at the lifting slide 22 slides along the lifting slide 22 on both sides. With the elastic connection of the spring 25 and the sliding of the slider 23 and the lifting slide 22, the lifting collar 18 is moved up and down along the food-grade detergent tank 14 by manual control, thereby driving the piston plate 27 to rise and fall along the inner wall of the food-grade detergent tank 14, thereby applying pressure to the food-grade cleaning liquid located on the lower side of the piston plate 27, and then flowing out through the outlet.

[0024] A sealing plate 28 is hinged at the output port and swings outward toward the output port. When the piston plate 27 moves downward, it applies an outward swinging force to the sealing plate 28, thereby opening the output port. When the piston plate 27 rises, it applies an adsorption force to the sealing plate 28, thereby controlling it to close the output port, thus realizing the function of automatically transferring food-grade cleaning liquid toward the coffee machine brewing device outlet pipe 10.

[0025] The cleaning agent inlet valve 19 is also located on the outer wall of the food-grade cleaning agent tank 14 on the lower side of the bottom of the lifting slide 22, ensuring that the inlet food-grade cleaning liquid is directly placed under the piston plate 27.

[0026] The cleaning agent inlet valve 19 can adopt the same connection structure as the cleaning agent outlet connection female valve 20 and the cleaning agent outlet connection male valve 21. The specific connection structure depends on the actual situation and will not be described in detail here.

[0027] It should be noted that the maximum height of the piston plate 27 is below the bottom of the lifting slide 22 to prevent external gas from entering between the piston plate 27 and the bottom of the food-grade cleaning agent tank 14 due to the opening of the lifting slide 22, which would cause air pressure leakage and leakage of food-grade cleaning liquid.

[0028] Finally, the connection structure or distribution method between the coffee machine brewing device outlet pipe 10 and the coffee machine can be referred to the relevant patent technology in the background art, and will not be repeated here.

[0029] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control.

[0030] Connect the connecting sleeve 12 to the output end 11, ensure a seal with the sealing ring 13, insert the cleaning agent output connection female valve 20 and the cleaning agent output connection male valve 21, connect the food-grade cleaning agent tank 14 and the outlet pipe 10, manually press down the lifting collar 18 → drive the slider 23 to move down along the slide 22 → drive the piston plate 27 to press down; the cleaning liquid pushes open the sealing plate 28 and flows into the outlet pipe 10 → flushing the residual coffee grounds and foam in the pipe;

[0031] Waste liquid is introduced into wastewater collection tank 15 through connecting sleeve 12 and telescopic hose 17.

[0032] Reset phase: Loosen the lifting collar 18 → Spring 25 rebounds and drives the piston plate 27 to rise → Sealing plate 28 adsorbs and closes the output port; Disassemble the cleaning device and the coffee machine resumes normal brewing process.

[0033] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0034] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
