Description

Technical Field

[0001] The utility model relates to a coffee machine, in particular to a drip control device of the coffee machine. Background Art

[0002] A drip coffee machine is a classic drip filter. After adding coffee powder into the funnel, it is directly brewed with boiling water under normal pressure. The brewed coffee has a pure taste and excellent taste. It is simple to use, efficient and reliable, and is suitable for home, office and dormitory use. Figure 1 As shown, the traditional drip coffee machine has a single function of the stop valve 1A, which can only be adapted to the special coffee pot 2A. The stop valve 1A is lifted up by the coffee pot 2A to create a gap between the stop valve 1A and the coffee pot 2A to achieve the function of drip coffee. The function has certain limitations. When used by individuals, the coffee must first be collected into the coffee pot 2A and then poured into the cup for drinking. The steps are cumbersome, the coffee temperature loses a lot, the coffee flavor is significantly reduced, and the user experience is poor. For this reason, Figure 1 As shown, the industry has designed an improved structure of a drip coffee machine, including a housing 1', a funnel 11' for holding coffee powder and brewing coffee, a coffee pot 12' for holding coffee, and a lever 2'. The funnel 11' is arranged in a funnel cavity 13' of the housing 1', and the coffee pot 12' is movably arranged in an open cavity 14' of the housing 1'. The funnel cavity 13' is located above the open cavity 14'. A leak-proof valve 15' is provided at the bottom of the funnel 11' for opening and closing the liquid outlet. When the coffee pot 12' is placed in the open cavity 14', the pot lid 121' of the coffee pot 12' pushes against the leak-proof valve 15', thereby connecting the funnel 11' with the coffee pot 12' and allowing coffee to flow into the coffee pot 12'. The lever 2' is located between the funnel cavity 13' and the open cavity 14' and is rotatably mounted on the housing 1'. The inner end of the lever 2' pushes against the leak-proof valve 15', thereby opening the liquid outlet and allowing coffee to flow out. This allows the user to use containers other than the matching coffee pot to hold coffee, thereby increasing the flexibility of the coffee machine. However, the lever 2' on this coffee machine is an independent component and is relatively complicated to assemble. Utility Model Content

[0003] The purpose of the utility model is to provide a drip control device for a coffee machine which is easy to operate and has a simple structure.

[0004] To achieve the above objectives, the technical solution of the present invention is:

[0005] The utility model discloses a drip control device for a coffee machine, comprising a funnel, a leak-stop valve and a spring; a leak-stop valve for opening and closing a liquid outlet is provided at the bottom of the funnel, and a spring is provided between the funnel and the leak-stop valve; the characteristic is that a guide rail is provided on the side wall of the liquid outlet of the funnel; the leak-stop valve comprises a valve body, a shift rod, a valve column and a sealing ring; the valve body is sleeved on the outer side of the liquid outlet of the funnel, and a liquid outlet opposite to the liquid outlet of the funnel is provided in the middle part of the valve body, the shift rod is fixed on the outer wall of the valve body, a valve column is provided in the middle part of the valve body, and the valve column is provided with a raised guide block, which is slidably connected to the guide rail of the funnel and the guide block can slide along the guide rail and stay at the end of the travel of the guide rail, a sealing ring is sleeved on the top of the valve column, and the sealing ring can seal the liquid outlet of the funnel, a spring is provided between the funnel and the valve body, and the sealing ring seals the liquid outlet of the funnel under normal circumstances.

[0006] Two guide rails are arranged opposite to each other on the side walls of the funnel liquid outlet; the guide rails of the funnel are composed of a surrounding inclined surface and a limiting plane, the surrounding inclined surface is arranged on the inner side wall of the liquid outlet and is inclined upward, and the upper end of the surrounding inclined surface is connected with the limiting plane; the guide block on the valve column can slide upward along the surrounding inclined surface of the guide rail and be clamped on the limiting plane of the guide rail.

[0007] The middle part of the valve body of the leak-proof valve is provided with multiple support bars, the outer ends of the multiple support bars are fixed on the outer wall of the valve body, the middle parts of the multiple support bars are connected, and the valve column is vertically fixed at the middle joint of the multiple support bars.

[0008] After adopting the above scheme, the utility model has the following advantages:

[0009] 1. Since the leak-proof valve of the utility model includes a valve body, a lever, a valve column, and a sealing ring, the leak-proof valve is changed to a lever with function switching, which has a simple structure. The inner cavity at the bottom of the funnel is provided with a two-stage surrounding inclined surface structure. When the lever is turned, the valve body is driven to rotate. The guide block on the valve column installed on the valve body can slide along the guide rail and stay on the guide rail, so that the sealing ring on the valve column is separated from the liquid outlet on the funnel. The liquid will flow along the liquid outlet of the funnel through the liquid outlet on the valve body and then flow out.

[0010] 2. Due to the two-stage surrounding inclined surface structure of the inner cavity at the bottom of the funnel of the utility model, the first section is a surrounding inclined surface structure, and the sealing ring on the valve column can slide on its surrounding inclined surface and be lifted or lowered at the same time. The second section is a limit plane. After the lever is lifted along the surrounding inclined surface to a certain height and passes the limit point, it remains lifted to allow the coffee liquid to flow out. By controlling the spatial position of the leak-proof lever, while retaining the original function of the leak-proof valve, a new "personal mode" is added, that is, manual control of coffee liquid outflow, without the need for a dedicated coffee pot.

[0011] 3. The utility model simplifies the operation steps for personal use by users, reduces the loss of coffee temperature, retains the coffee flavor and aroma to a greater extent, is easy to operate, and enhances user experience.

[0023] A leak-stop valve 2 for opening and closing the liquid outlet 11 is provided at the bottom of the funnel 1 , and a spring 3 is provided between the funnel 1 and the leak-stop valve 2 .

[0024] Two guide rails 12 are provided on the side walls of the liquid outlet 11 of the funnel 1 and are arranged opposite to each other.

[0025] The stop valve 2 includes a valve body 21, a lever 22, a valve column 23, and a sealing ring 24; the valve body 21 is sleeved on the outside of the liquid outlet 11 of the funnel 1, and the middle part of the valve body 21 has a liquid outlet 211 opposite to the liquid outlet 11 of the funnel 1, the lever 22 is fixed on the outer wall of the valve body 21, and a valve column 23 is provided in the middle part of the valve body 21, and the valve column 23 is provided with a raised guide block 231, which is slidably connected to the guide rail 12 of the funnel 1 and the guide block 231 can slide along the guide rail 12 and stay at the end of the stroke of the guide rail 12, and a sealing ring 24 is sleeved on the top of the valve column 23, which can seal the liquid outlet 11 of the funnel 1, and a spring 3 is provided between the funnel 1 and the valve body 21. Under normal circumstances, the sealing ring 24 seals the liquid outlet 11 of the funnel 1.

[0026] The guide rail 12 of the funnel 1 is composed of a surrounding inclined surface 121 and a limiting plane 122. The surrounding inclined surface 121 is arranged on the inner wall of the liquid outlet 11 and is inclined upward. The upper end of the surrounding inclined surface 121 is connected to the limiting plane 122; the guide block 231 on the valve column 23 can slide upward along the surrounding inclined surface 121 of the guide rail 12 and be clamped on the limiting plane 122 of the guide rail 12.
