Description

Technical Field

[0001] The utility model relates to the technical field of coffee pots, in particular to a coffee pot structure with a constant dripping speed. Background Art

[0002] Ice drip coffee uses ice water, cold water or ice cubes to extract coffee. Generally, a slow drip rate of about 7 drops per 10 seconds is used to continuously extract coffee powder. This extraction process is very slow and often takes several hours. The drip rate of existing coffee ice drip pots is affected by changes in water pressure. The drip rate is faster in the front section and slower in the rear section, making it difficult for operators to control the drip rate, affecting the extraction effect and user experience.

[0018] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0019] Example: As shown in the attached Figure 1-5As shown, the utility model is a coffee pot structure with a constant dripping speed, comprising a pot body 1, a cover body installed on the top of the pot body 1, the cover body and the pot body 1 are detachably connected, the cover body can be directly buckled on the pot body 1, the bottom of the cover body is provided with a plug-in portion adapted to the pot body 1, a water storage cavity is provided in the cover body, an air guide tube 2 communicating with the water storage cavity is provided at the bottom of the cover body, an air inlet hole communicating with the water storage cavity is provided at the top of the outer wall of the cover body, and the outside air enters the water storage cavity through the air inlet hole and is discharged through the air guide tube 2, a valve 3 is provided at the bottom of the pot body 1, and a water outlet 4 is provided at the bottom of the valve 3; after the cover body is installed on the pot body 1, the air inlet hole is located on the outside of the pot body 1, and the bottom end of the air guide tube 2 is located above the bottom surface in the pot body 1, and preferably, the axis center lines of the cover body, the air guide tube 2, the pot body 1 and the water outlet 4 coincide.

[0020] Preferably, in order to facilitate the manufacture of the cover body, the cover body includes an upper cover 5 and a lower cover 6. The bottom of the upper cover 5 is a cylinder extending downward, and the top of the lower cover 6 is open. An external thread can be processed on the cylinder at the bottom of the upper cover 5, and an internal thread can be processed on the top inside the lower cover 6. The upper cover 5 is threadedly connected with the lower cover 6. A water storage bin 7 is provided at the bottom of the lower cover 6, and the water storage cavity is located in the water storage bin 7. The air guide pipe 2 is fixed to the bottom of the water storage bin 7.

[0021] Furthermore, in order to ensure the air supply to the air inlet, a first air inlet 8 is provided on the outer wall of the cylinder at the bottom of the upper cover 5, and a second air inlet 9 is provided on the outer wall of the top of the lower cover 6. After the upper cover 5 is installed on the lower cover 6, the overlapping part of the first air inlet 8 and the second air inlet 9 or the part of the first air inlet 8 not blocked by the lower cover 6 is the air inlet.

[0022] Preferably, the inner diameter of the water storage chamber gradually decreases from top to bottom.

[0023] Preferably, in order to ensure the sealing between the cover body and the kettle body, a silicone sealing ring 10 is provided on the lower cover 6 , and the silicone sealing ring 10 is located above the water storage bin 7 .

[0024] The utility model is assembled as follows: the upper cover 5 and the lower cover 6 are assembled by threads; the air guide tube 2 and the water storage tank 7 are airtightly assembled, so that the upper cover 5, the lower cover 6 and the air guide tube 2 form a whole, and the whole is airtightly assembled with the kettle body 1 through a silicone sealing ring 10. Figure 2 A and B in the figure maintain an airtight assembly during the operation of the product.

[0025] When the utility model is used, a proper amount of ice-water mixture is added to the kettle body 1, and the upper cover 5, the lower cover 6 and the air guide tube 2 are pressed against the kettle body 1. At this time, part of the water will enter the air guide tube 2 and the water storage bin 7 (such as the attached Figure 3After the valve 3 is opened, as the water drips out from the water outlet 4, the water in the water storage tank 7 will flow back to the kettle body 1 through the air guide tube 2. As the water drips out further, the external air is pressed into the water along the following path: outside - air inlet - air guide tube 2 - below the water surface (as shown in the attached figure). Figure 2 The dotted path in the figure). When external air enters the water, small bubbles of equal volume will appear in the air tube 2 moving at a uniform speed, and the bubbles will float to the surface from the bottom outlet of the air tube 2. This structure uses the principle of the Mallett bottle, and the air tube 2 inserted below the water surface changes the pressure distribution in the kettle body 1. External air is introduced into the position near the bottom of the kettle body 1 through the air tube 2, so that a constant pressure is maintained at the water outlet 4 (that is, a constant atmospheric pressure and the pressure brought by a water column of constant height), thereby keeping the water dripping rate constant. This constant state starts when the water column in the air tube 2 is emptied, and ends when the liquid level is lower than the bottom end of the air tube 2 (as shown in the attached figure). Figure 5 shown).

[0026] Advantages of the utility model: Ice drip coffee generally uses a slow drip rate of about 7 drops per 10 seconds to continuously extract coffee powder, which usually takes several hours. The drip rate of existing coffee ice drip pots is easily affected by changes in water pressure. The drip rate in the front section is faster and the drip rate in the rear section is slower, making it difficult for operators to control the drip rate, affecting the extraction effect and user experience. The utility model can keep the drip rate of the ice drip pot constant throughout the process, helping the operator to more easily control the drip rate, and there is no need to frequently adjust or check the coffee ice drip pot during use.
