[0031] The coffee pot 100 provided by the embodiments of the application will be described in detail below in combination with all the drawings and specific embodiments.

[0032] Please refer to Figure 1 And Figure 2 The utility model discloses a coffee pot 100, including the body 10 and the neck 20, the body 10 is seted up with the accommodation cavity 102 and multiple guide grooves 104, and the guide groove 104 is seted up in the inside cavity wall of the accommodation cavity 102, all guide grooves 104 are arranged around the accommodation cavity 102, and the guide groove 104 is inclined relative to the horizontal plane, the neck 20 is seted up with the opening 202, the body 10 is connected with the neck 20, and the accommodation cavity 102 is communicated with the outside through the opening 202.

[0033] Generally, there can be part of undissolved coffee solute and gas produced by coffee solvent in the coffee solution. Through the above structure, the guide groove 104 is set up in the inside cavity wall of the accommodation cavity 102, and then when the user pours coffee into the coffee pot 100, the coffee can flow into the guide groove 104, and then the coffee can flow along the guide groove 104 to the bottom of the accommodation cavity 102 and flow into the accommodation cavity 102 from the bottom of the accommodation cavity 102.

[0034] The guide groove 104 is inclined relative to the horizontal plane, so that the coffee has a horizontal flow speed when flowing along the guide groove 104, and when the coffee contacts the bottom cavity wall of the accommodating cavity 102, the coffee has a tendency to flow circumferentially along the accommodating cavity 102, and then the coffee poured into the accommodating cavity 102 can form a rotating vortex, and the guide groove 104 makes the side surface of the accommodating cavity 102 uneven, and the vortex formed by the coffee continuously impacts the groove wall of the accommodating cavity 102, so that the coffee is fully volatilized and oxidized to produce a rich coffee aroma. In addition, when the user shakes the coffee cup 100, the coffee in the accommodating cavity 102 can more violently impact the groove wall of the accommodating cavity 102, which can further improve the volatilization and oxidation degree of the coffee.

[0035] Specifically, in the embodiment, the coffee pot 100 can be made of transparent materials such as glass; the accommodating cavity 102 can be similar to a circular truncated cone, and the area of one end of the accommodating cavity 102 facing the spout 20 is smaller than the area of the other end of the accommodating cavity 102 away from the spout 20. All the guide grooves 104 can be uniformly arranged around the accommodating cavity 102, and two adjacent guide grooves 104 are connected to each other, and all the guide grooves 104 form a shape similar to a sawtooth in a top view.

[0036] In the horizontal direction, the cross section of the spout 20 can be circular, and in the direction from the pot body 10 to the spout 20, the cross-sectional area of the spout 20 first decreases and then increases, and the side wall of the spout 20 is a smooth curved surface, and the thickness of the spout 20 is uniform.

[0037] In other embodiments, the coffee pot 100 can also be made of other opaque materials, such as ceramic; the accommodating cavity 102 can also have other structures, such as a circular cylinder, or in the direction from the pot body 10 to the spout 20, the cross-sectional area of the accommodating cavity 102 first increases and then decreases; the guide grooves 104 can also be distributed on one side of the pot body 10; there can be gaps between two adjacent guide grooves 104; and the spout 20 can also have other structures, such as a circular truncated cone, and in the direction from the pot body 10 to the spout 20, the cross-sectional area of the opening 202 gradually increases.

[0038] In some embodiments, in the direction from the opening 202 to the accommodating cavity 102, the cross-sectional area of the accommodating cavity 102 gradually increases, and the cross-sectional area of the guide groove 104 gradually increases.

[0039] Through the above structure, in the direction from the opening 202 to the accommodating cavity 102, the cross-sectional area of the accommodating cavity 102 gradually increases; and the side cavity wall of the accommodating cavity 102 is inclined, and the guide groove 104 is opened on the inner side cavity wall of the accommodating cavity 102, so that the guide groove 104 can have a greater inclination, and the coffee solution flowing along the guide groove 104 to the bottom of the accommodating cavity 102 can have a greater horizontal speed.

[0040] In addition, the cross-sectional area of the side of the accommodating cavity 102 away from the opening 202 is larger, so that a larger vortex can be formed at the bottom of the accommodating cavity 102, to accelerate the speed of the solute in the coffee to dissolve into the solvent, and the gas generated when the coffee is dissolved can be separated from the coffee solution more quickly, to further improve the taste of the coffee when the user drinks the coffee; meanwhile, the gas in the accommodating cavity 102 can be gathered at the opening 202 with a smaller cross-sectional area, to produce a more intense coffee flavor. The cross-sectional area of the side of the guide groove 104 away from the opening 202 is larger, so that the coffee flowing along the guide groove 104 will not separate from the guide groove 104.

[0041] Specifically, in the embodiment, the accommodating cavity 102 can be a circular truncated cone as a whole. In other embodiments, the cross section of the accommodating cavity 102 in the horizontal direction can also be other shapes, such as an ellipse or a rectangle.

[0042] In some embodiments, the central axis of the accommodating cavity 102 is perpendicular to the horizontal plane, and the cross-sectional area of the guide groove 104 gradually decreases in the direction away from the central axis of the accommodating cavity 102.

[0043] Through the above structure, the cross-sectional area of the guide groove 104 gradually decreases in the direction away from the central axis of the accommodating cavity 102; when the user pours coffee into the accommodating cavity 102, the coffee contacts the groove wall of the guide groove 104 and flows downward along the guide groove 104, and the coffee liquid in the guide groove 104 can be closer to the accommodating cavity 102, so that the vortex formed when the coffee flows into the accommodating cavity 102 through the guide groove 104 is larger, and the coffee in the vortex can hit the groove wall of the guide groove 104 more violently, to further increase the volatilization and oxidation of the coffee liquid, to produce a more intense aroma.

[0044] Specifically, in the embodiment, the groove wall of the guide groove 104 can be an arc surface structure. In other embodiments, the guide groove 104 can also be other structures, for example, the cross section of the guide groove 104 in the horizontal direction is a trapezoid.

[0045] Please refer to Figure 3 and Figure 4 In some embodiments, the groove wall of the guide groove 104 includes a first side wall 14 and a second side wall 16, and all the first side walls 14 and the second side walls 16 of the guide grooves 104 are arranged alternately in sequence in the horizontal direction; the first side wall 14 and the second side wall 16 are both smooth curved surfaces, the side of the first side wall 14 away from the accommodating cavity 102 is connected with the side of the second side wall 16 away from the accommodating cavity 102, and the area of the first side wall 14 is larger than that of the second side wall 16; in the horizontal direction, the first side wall 14 and the second side wall 16 form an obtuse angle.

[0046] The cavity wall of the accommodating cavity 102 comprises arc curved surfaces 18 located between two adjacent guide grooves 104, which protrude towards the accommodating cavity 102.

[0047] Through the above structure, the first side wall 14 and the second side wall 16 are both smooth curved surfaces, and in the horizontal direction, the first side wall 14 and the second side wall 16 form an obtuse angle, so that the coffee liquid can flow more smoothly in the guide groove 104; the area of the first side wall 14 is larger than that of the second side wall 16, so that the coffee liquid in the guide groove 104 can have a greater tendency to flow horizontally, thereby increasing the vortex formed when the coffee flows into the accommodating cavity 102.

[0048] In addition, the areas of the arc curved surfaces 18, the first side wall 14 and the second side wall 16 are different, and in the process of shaking the coffee pot 100, the coffee in the accommodating cavity 102 can hit the multiple arc curved surfaces 18, the multiple first side walls 14 and the multiple second side walls 16 in different angles in sequence, and different sounds can be produced when the coffee hits the different arc curved surfaces 18, the first side wall 14 and the second side wall 16 in sequence, so as to form a pleasant music.

[0049] The first side wall 14 and the second side wall 16 of all the guide grooves 104 are arranged alternately in sequence in the horizontal direction, the arc curved surface 18 is located between two adjacent guide grooves 104, and the arc curved surface 18 protrudes towards the accommodating cavity 102, so that when the user shakes the coffee pot 100, part of the coffee in the accommodating cavity 102 can hit the arc curved surface 18 and then flow into the guide groove 104, so as to further improve the evaporation rate of the coffee and the dissolution rate of the coffee.

[0050] Specifically, in the present embodiment, the first side wall 14 and the second side wall 16 both fit to form a structure similar to a rectangle, and the first side wall 14 and the second side wall 16 are both arc surfaces; in the horizontal direction, the width of the first side wall 14 is greater than that of the second side wall 16, and in the vertical direction, the length of the first side wall 14 is equal to that of the second side wall 16, so that the area of the first side wall 14 is greater than that of the second side wall 16; the first side wall 14 and the second side wall 16 of all the guide grooves 104 are arranged around the accommodating cavity 102 to form a circular ring.

[0051] In other embodiments, the first side wall 14 and the second side wall 16 can also have other structures, such as an elliptical shape; the shape and size of the first side wall 14 can also be the same as those of the second side wall 16.

[0052] In some embodiments, the first side wall 14 in one guide groove 104 has a different area than the first side wall 14 in the adjacent guide groove 104; the angle between the first side wall 14 and the second side wall 16 in one guide groove 104 is a first preset angle, the angle between the first side wall 14 and the second side wall 16 in the adjacent guide groove 104 is a second preset angle, and the first preset angle is different from the second preset angle.

[0053] Through the above structure, when the user shakes the coffee pot 100, the coffee in the coffee pot 100 can hit into multiple guide grooves 104 at the same time, the size and structure of the adjacent two guide grooves 104 are different, and then the coffee liquid hitting into different guide grooves 104 will produce different sounds to produce more diverse music.

[0054] Specifically, in the present embodiment, the first preset angle can be 100 degrees, and the second preset angle can be 120 degrees; in other embodiments, the first preset angle can be other degrees, for example, 150 degrees, and the second preset angle can also be other angles, for example, 130 degrees.

[0055] In some embodiments, the height of the accommodating cavity 102 is greater than the height of the guide groove 104, the top of the accommodating cavity 102 is flush with the top of the guide groove 104, and the bottom cavity wall of the accommodating cavity 102 is below the bottom groove wall of the guide groove 104.

[0056] Through the above structure, the top of the accommodating cavity 102 is flush with the top of the guide groove 104, so that when the user pours coffee into the accommodating cavity 102, the coffee can directly flow into the guide groove 104, and then the guide groove 104 can have a better guiding effect on the coffee.

[0057] In addition, the bottom cavity wall of the accommodating cavity 102 is below the bottom groove wall of the guide groove 104, and then the side cavity wall of the bottom of the accommodating cavity 102 is smooth; so that when the coffee flows out of the guide groove 104 through the lower end of the guide groove 104, it can continue to flow downward, and the coffee is more easily formed into a vortex at the bottom wall of the accommodating cavity 102, so that the solute in the coffee can be more quickly dissolved into the solvent, and the gas generated when the coffee is dissolved can be more quickly separated from the coffee solution, to further improve the taste of the coffee when the user drinks it; and further increase the degree of impact of the coffee with the groove wall of the guide groove 104, to improve the degree of volatilization of the coffee and increase the degree of richness of the coffee taste at the opening 202.

[0058] Specifically, in the present embodiment, the part of the accommodating cavity 102 below the guide groove 104 is similar to a circular truncated cone, and the area of the part of the accommodating cavity 102 below the guide groove 104 near one side of the opening 202 is larger.

[0059] In other embodiments, the portion of the accommodation cavity 102 below the guide groove 104 can also have other shapes, such as a cylinder or a cuboid.

[0060] In some embodiments, the bottom cavity wall of the accommodation cavity 102 protrudes into the accommodation cavity 102, and the bottom cavity wall of the accommodation cavity 102 has an arc surface structure.

[0061] Through the above structure, the bottom cavity wall of the accommodation cavity 102 protrudes into the accommodation cavity 102, so that when the coffee liquid flows from the bottom of the guide groove 104 to the bottom of the accommodation cavity 102, it is difficult for the coffee liquid to flow to the center of the accommodation cavity 102, so that the coffee liquid can generate a greater degree of vortex at the bottom of the accommodation cavity 102; the bottom cavity wall of the accommodation cavity 102 has an arc surface structure, so that the coffee can flow more stably around the bottom cavity wall of the accommodation cavity 102.

[0062] Specifically, the bottom cavity wall of the accommodation cavity 102 can be part of a spherical surface, so that the bottom cavity wall of the accommodation cavity 102 is smoother.

[0063] In some embodiments, the cross-sectional area of the portion of the accommodation cavity 102 below the guide groove 104 gradually decreases from the opening 202 to the accommodation cavity 102.

[0064] Through the above structure, the cross-sectional area of the portion of the accommodation cavity 102 below the guide groove 104 gradually decreases from the opening 202 to the accommodation cavity 102, and the side cavity wall of the bottom of the accommodation cavity 102 is inclined; during the process that the coffee flows out from the bottom of the guide groove 104 and contacts the side cavity wall of the accommodation cavity 102, the side cavity wall of the bottom of the accommodation cavity 102 can continue to guide the coffee, so that the coffee can flow more stably around the bottom cavity wall of the accommodation cavity 102.

[0065] Specifically, the portion of the accommodation cavity 102 below the guide groove 104 has a structure similar to a circular truncated cone, and a smooth fillet is arranged between the bottom of the side cavity wall of the accommodation cavity 102 and the bottom wall of the accommodation cavity 102.

[0066] In some embodiments, the cross-sectional area of the opening 202 first decreases and then increases from the opening 202 to the accommodation cavity 102, the side surface of the opening 202 is a smooth curved surface, and the cross-section of the opening 202 is circular.

[0067] Through the above structure, the cross-sectional area of the opening 202 first decreases and then increases from the opening 202 to the accommodation cavity 102, and the side surface of the opening 202 is a smooth curved surface; so that when the user needs to pour out the coffee in the coffee pot 100, the user will tilt the coffee pot 100, and when the coffee pot 100 is tilted, the coffee can flow out smoothly through the opening 202.

[0068] In addition, the cross-sectional area of the accommodating cavity 102 gradually increases from the opening 202 to the accommodating cavity 102, and the cross-sectional area of the guiding groove 104 gradually increases from the opening 202 to the accommodating cavity 102. The cross-sectional area of the opening 202 first decreases and then increases from the opening 202 to the accommodating cavity 102, so that the coffee pot 100 has a shape of large body 10 and small opening 202. The gas generated by the evaporation of coffee is more easily gathered in the part of the opening 202 with a smaller cross-section, which is beneficial to produce a more concentrated coffee flavor.

[0069] Specifically, the central axis of the opening 202 is collinear with the central axis of the accommodating cavity 102. In the horizontal direction, the cross-sectional area of the opening 202 is smaller than the cross-sectional area of the upper end of the accommodating cavity 102.

[0070] In some embodiments, the coffee pot 100 further comprises a spout 30 connected to one side of the body 10. The spout 30 is located at one end of the opening 202 away from the accommodating cavity 102.

[0071] The connection between the spout 30 and the body 10 is a smooth curved surface. The horizontal cross-section of the spout 30 is triangular. The cross-sectional area of the spout 30 gradually decreases from the opening 202 to the accommodating cavity 102.

[0072] Through the above structure, when the user pours out the coffee in the coffee pot 100, the user will tilt the coffee pot 100 and align the spout 30 with a container for drinking coffee, such as a coffee cup. The connection between the spout 30 and the body 10 is a smooth curved surface, so that the coffee in the accommodating cavity 102 can flow stably into the container through the opening 202 and the spout 30.

[0073] Specifically, the height of the spout 30 is smaller than the height of the neck 20, and the top of the spout 30 is flush with the top of the neck 20.

[0074] In some embodiments, the body 10 comprises a plurality of protrusions 12. The plurality of protrusions 12 are protruded from the outer circumferential surface of the body 10 and uniformly distributed along the outer circumferential surface of the body 10. Each guiding groove 104 corresponds to one protrusion 12, so that the thickness of the body 10 is consistent.

[0075] Through the above structure, the plurality of protrusions 12 are protruded from the outer circumferential surface of the body 10 and uniformly distributed along the outer circumferential surface of the body 10. The protrusions 12 make the outer surface of the coffee pot 100 more rough, so that the user can hold the coffee pot 100 when picking it up, thereby reducing the possibility of the coffee pot 100 falling.

[0076] Specifically, the shape of the protrusion 12 is the same as the shape of the guiding groove 104, so that each guiding groove 104 corresponds to one protrusion 12, and the thickness of the body 10 is consistent.
