[0031] A spraying structure of a coffee barrel, please refer to Figures 1-5, including a spraying structure 100 which is arranged in a coffee barrel. The coffee barrel is an electrical appliance usually used for commercial purposes to make American coffee. The coffee barrel is in a barrel shape and generally also includes a lid. The coffee barrel can hold water or brewed coffee. A chassis 200 is arranged in the coffee barrel. The chassis 200 and the side wall of the coffee barrel form a barrel-shaped structure, enabling the coffee barrel to hold liquid. The chassis 200 in this embodiment is in a circular shape, but its shape is not limited to this embodiment. In other embodiments, the chassis 200 can be of other shapes. The side wall of the coffee barrel matches the shape of the chassis 200, that is, the outer shell of the coffee barrel connecting the chassis 200 is in a cylindrical structure. The outer shell structure of the coffee barrel is ignored in the drawings. A heating plate 210 is arranged below the chassis 200. The heating plate 210 generates heat and transfers the heat to the chassis 200 to heat the liquid in the coffee barrel. The spraying structure 100 is provided with a spraying cover 110. The spraying cover 110, as the base of the spraying structure 100, can be detachably placed on the chassis 200, enabling the spraying structure 100 to be directly taken out of the coffee barrel without disassembly, which is convenient for users to clean the coffee barrel or the spraying structure 100.

[0032] Furthermore, a spraying pipe 120 is arranged on the spraying cover 110. The bottom of the spraying pipe 120 is connected to the spraying cover 110, and a coffee sieve 130 is arranged at the top. The coffee sieve 130 is in a basin shape and can hold coffee beans or coffee powder for making coffee. When the heating plate 210 heats the liquid in the coffee barrel, the liquid is usually drinking water. After the liquid is heated and boils, it is pumped upward through the spraying pipe 120 and sprayed out from the spraying head 131 provided on the coffee sieve 130. The water sprays onto the coffee beans or coffee powder to extract coffee liquid. A cavity 220 is formed between the spraying cover 110 and the chassis 200. A plurality of through holes 111 are arranged on the surface of the spraying cover 110. When a traditional coffee barrel works and extracts coffee through the spraying structure, debris of coffee beans or coffee powder and other residues may fall onto the chassis. After continuous heating, the residues will stick to the chassis to form black spots or black blocks, which are difficult to clean and will affect the heating effect and service life of the coffee barrel. Especially in the past, some coffee barrels were designed with a heating element having a groove structure, and the residues would accumulate on the chassis with a matching groove structure, and the residues could not be discharged, accelerating the formation of black spots or black blocks. The utility model covers the chassis 200 with the spraying cover 110 to prevent residues from directly falling onto the area of the chassis 200 corresponding to the heating plate 210, so as to overcome the shortcomings of the traditional structure. When the residues on the chassis 200 outside the heating plate 210 enter the cavity 220, the boiling liquid inside can stir up the residues and enable the residues to be discharged outside the spraying cover 110 through the through holes 111, preventing the residues from accumulating in the cavity 220 and sticking to the chassis 200.

[0033] Furthermore, a movable piece 121 that can move up and down is provided at the bottom of the spray pipe 120. When the movable piece 121 moves up and down, it can close or open the through hole 111. When the coffee barrel is working, the liquid inside boils, and the tumbling of the water in the cavity 220 will cause the movable piece 121 to move up and down. When the movable piece 121 moves upward to cover the bottom of the through hole 111 to close it, it can prevent residues from falling into the cavity 220 through the through hole 111. When the movable piece 121 falls, the through hole 111 opens, and the residues in the cavity 220 can be driven by the tumbling during water boiling and discharged outside the spray cover 110 through the through hole 111, ensuring that too many residues will not accumulate in the cavity 220, and the residues will not adhere to the chassis 200 when the liquid boils and tumbles, preventing black spots or black blocks from forming on the chassis 200 during heating, affecting the heating effect, ensuring that the spray structure 100 can work properly to spray and extract coffee beans or coffee powder, guaranteeing the extraction effect of coffee, and effectively extending the service life.

[0034] Furthermore, a convex platform 230 that matches the size of the heating plate 210 is provided on the chassis 200. The surface of the convex platform 230 is a flat structure. The size ratio of the chassis 200 and the heating plate 210 is not limited to the specifications shown in the drawings of this embodiment. For coffee barrels of different specifications, larger or smaller chassis 200 and heating plates 210 can be set to meet different usage requirements. For example, the chassis 200 used for a smaller coffee barrel will be smaller, while a larger coffee barrel requires a larger chassis 200. Generally, a larger chassis 200 will have a correspondingly larger heating plate 210 to provide sufficient heating power to heat a larger volume of liquid; the convex platform 230 protrudes upward on the chassis 200, and the size of the heating plate 210 matches that of the convex platform 230, so that the heating area on the chassis 200 corresponds to the convex platform 230. The upwardly protruding convex platform 230 can reduce the probability of coffee residues outside entering its surface, and the flat structure of the convex platform 230 can also prevent residues above it from accumulating in a certain position, while being beneficial to the heating of the liquid; the convex platform 230 matches the size and shape of the spray cover 110, so that the spray cover 110 can be stably placed on the chassis 200 by buckling on the convex platform 230. At the same time, the convex platform 230 can also be used for positioning when the spray structure 100 is placed, facilitating the user to place the spray structure 100 in the coffee barrel.

[0035] Furthermore, the spray cover 110 is a convex cover structure, so that a cavity 220 is formed between its inner side and the chassis 200. The liquid in the cavity 220 boils and tumbles after heating, enabling the liquid to be smoothly pumped upward through the spray pipe 120 and preventing residues from staying and accumulating on the boss 230. A support ring 122 extending outward is provided below the spray pipe 120, and a connection hole 112 is provided in the center of the spray cover 110. The size of the connection hole 112 matches that of the spray pipe 120. The bottom end of the spray pipe 120 passes through the spray cover 110 through the connection hole 112 and is clamped on the spray cover 110 through the support ring 122. The support ring 122 and the connection hole 112 form a clamping position, fixing the spray pipe 120 after it passes through the spray cover 110 and preventing it from falling further, ensuring that the bottom of the spray pipe 120 does not contact the chassis 200, so that water can be pumped upward through the spray pipe 120. The through hole 111 is provided outside the connection hole 112, so that after the movable piece 121 moves upward, it fits against the bottom of the spray cover 110 to close the through hole 111.

[0036] Furthermore, a fixing ring 123 is provided at the bottom end of the spray pipe 120. The movable piece 121 is provided with an opening, and the movable piece 121 is sleeved on the spray pipe 120 through the opening. The movable piece 121 is located above the fixing ring 123. During processing, after the spray pipe 120 is embedded in the spray cover 110, the movable piece 121 is sleeved into the spray pipe 120 from the bottom, and finally the fixing ring 123 is welded to the spray pipe 120. The fixing ring 123 can prevent the spray cover 110 and the movable piece 121 from falling off, making the spray cover 110, the movable piece 121, and the spray pipe 120 form an integral body, and the movable piece 121 can move up and down between the fixing ring 123 and the spray cover 110.

[0037] Furthermore, a connection groove 132 is provided at the bottom of the coffee sieve 130 below the spray head 131. The spray pipe 120 is connected to the coffee sieve 130 by being embedded in the connection groove 132. This structure facilitates the disassembly and assembly of the coffee sieve 130, and when the user uses it, the coffee sieve 130 can be taken out separately for loading or replacing coffee beans and coffee powder. The spray head 131 is provided with a spray port 133 communicating with the spray pipe 120. The water pumped from the spray pipe 120 is sprayed out through the spray port 133 and can be smoothly sprayed onto the coffee beans or coffee powder on the coffee sieve 130. A plurality of sieve holes 134 are provided at the bottom of the coffee sieve 130. After the sprayed coffee beans or coffee powder are extracted to form coffee liquid, the coffee liquid falls through the sieve holes 134 to the bottom and is mixed with the liquid below the coffee sieve 130. Generally, the water level in the coffee bucket is lower than the bottom of the coffee sieve 130. After the coffee beans or coffee powder on the coffee sieve 130 are sprayed and extracted multiple times, the water in the coffee bucket is completely formed into coffee liquid. An outlet for discharging the coffee liquid is usually provided on the side of the coffee bucket.

[0038] Furthermore, a spring 140 is provided between the spray pipe 120 and the coffee sieve 130; a snap ring 124 for supporting the spring 140 is provided on the side of the spray pipe 120. The snap ring 124 is integrally formed on the spray pipe 120. The snap ring 124 supports the bottom of the spring 140. The spring 140 is sleeved on the spray pipe 120. The top of the spring 140 is in close contact with the coffee sieve 130. Generally, a spring groove matching the spring 140 is provided at the bottom of the coffee sieve 130. The spring 140 can be accommodated in the spring groove. The spring 140 plays a buffering role for the coffee sieve 130, preventing the coffee sieve 130 from shaking excessively and improving the connection stability between the coffee sieve 130 and the spray pipe 120.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
