Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a fixing structure for a steam pipe. Background Art

[0002] The steam pipe is an important component of a coffee machine for making coffee, and is used to output high-temperature steam to complete operations such as coffee extraction, milk foam preparation, and utensil cleaning. The steam pipe is usually fixedly arranged on the coffee machine and connected to a steam generator through a pipeline. For the convenience of use, the steam pipe is rotatably installed on the coffee machine so that the position of the air outlet nozzle of the steam pipe can be adjusted. For this purpose, Chinese Patent CN201734533U discloses an adjustment and positioning structure for the steam pipe of a coffee machine, including a steam pipe arranged on the coffee machine, a flange is arranged at the air inlet end of the steam pipe, and an adjustment and positioning mechanism is arranged between the flange of the steam pipe and the coffee machine. The adjustment and positioning mechanism includes an adjustment sleeve arranged on the steam pipe corresponding to the position of the flange and a rotating shaft sleeve rotatably connected to the adjustment sleeve. A concave positioning groove in the shape of a gear is arranged inside the rotating shaft sleeve, and 1-6 elastic bumps are arranged on the outer wall of the adjustment sleeve corresponding to the position of the concave positioning groove. A concave cavity corresponding to the shape of the flange is arranged at the bottom of the adjustment sleeve.

[0003] In the above prior art, the adjustment sleeve on the steam pipe is rotatably connected to the rotating shaft sleeve, so that the steam pipe can rotate horizontally. And after the steam pipe is adjusted to a corresponding angle, the elastic bump is paired with the concave positioning groove to limit the loosening of the steam pipe. In order to expand the angle adjustment range of the steam pipe, on some coffee machine products, a universal ball head structure is also used to realize the angle adjustment function of the steam pipe. A supporting bracket with a spherical groove is arranged on the coffee machine, and a ball head structure is arranged on the steam pipe. The steam pipe can rotate by pairing the ball head structure with the supporting bracket. This kind of supporting bracket usually consists of two upper and lower cover bodies, and screws connect the two cover bodies to form a spherical groove therebetween. The ball head structure can rotate in the spherical groove and be clamped and locked by the cover bodies. However, whether the tightening force of the screws is too large or too small, it will cause the rotation flexibility of the steam pipe to decrease, affecting the user experience. Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fixing structure for a steam pipe with reasonable structure, small adjustment resistance and flexible rotation in view of the defects and deficiencies of the prior art.

[0005] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0006] A steam pipe fixing structure according to the present utility model includes a coffee machine main body and a steam pipe. The steam pipe is rotatably installed on the coffee machine main body through a supporting component. The supporting component includes a lining bracket, a clamping component, and an upper cover. The clamping component is movably disposed between the upper cover and the lining bracket, and the upper cover is fixedly connected to the lining bracket, so that an action cavity is formed between the clamping component and the lining bracket. A ball head structure is provided on the steam pipe, and the ball head structure is rotatably disposed in the action cavity. The supporting component is used to install the steam pipe on the coffee machine main body, and the steam pipe is rotatably connected to the coffee machine main body, so that the angle of the steam pipe can be adjusted. Specifically, the clamping component is movably disposed between the upper cover and the lining bracket, and the action of the clamping component can change the size of the space of the action cavity, so that the ball head structure can rotate more smoothly in the action cavity. In particular, the upper cover encapsulates the clamping component in the upper part of the action cavity. When there is no external force to push the steam pipe, the clamping component cooperates with the lining bracket, and the clamping component provides an appropriate clamping force to clamp the ball head structure to prevent the steam pipe from swinging.

[0007] According to the above solution, the clamping component includes a pressing cover and a rubber pad. The upper cover, the rubber pad, and the pressing cover are stacked on the lining bracket from top to bottom in sequence, and the action cavity is formed between the pressing cover and the lining bracket. The outer edge of the lower part of the ball head structure is in contact connection with the lining bracket, and the pressing cover is in contact connection with the outer edge of the upper part of the ball head structure. Further, after the upper cover is fixed to the lining bracket, the pressing cover and the lining bracket are paired to form an action cavity, and the ball head structure can rotate in the action cavity. Of course, the upper cover provides a pressure to the pressing cover through the rubber pad, so that the pressing cover pairs with the lining bracket to clamp the ball head structure, and the frictional force generated by the pressing cover and the lining bracket can prevent the ball head structure from rotating. When the angle of the steam pipe needs to be adjusted, only the pressure generated by the rubber pad needs to be overcome, so that the pressing cover moves upward to increase the space of the action cavity, so that the ball head structure can rotate flexibly in the action cavity, which is convenient for users to operate and improves the use experience.

[0008] According to the above solution, a through hole is provided in the upper cover, and the through hole penetrates through the upper and lower ends of the upper cover. The pressing cover is disposed in the lower port of the upper cover, a snap ring is provided in the upper port of the upper cover, and the rubber pad is clamped on the snap ring to be in top contact connection with the pressing cover. The through hole is used to accommodate the pressing cover and the rubber pad, so that the snap ring touches the rubber pad, the rubber pad touches the pressing cover, and the pressing cover clamps the ball head structure. When the steam pipe rotates, the pressing cover is subjected to the pressure of the ball head structure, overcomes the pressure of the rubber pad to deform it, and the pressing cover moves upward along the through hole to increase the space of the action cavity, so that the ball head structure can rotate flexibly in the action cavity.

[0009] According to the above solution, a clamping groove is provided on the buckle, and the rubber pad is in a horn shape. The large-mouth end of the rubber pad is clamped in the clamping groove, and the small-mouth end of the rubber pad abuts against and connects to the gland. The clamping groove can fix the rubber pad on the buckle, preventing the rubber pad from detaching between the buckle and the gland when deforming. Further, the small-mouth end of the horn-shaped rubber pad abuts against the gland. When a relatively small pressure is applied to the lower end of the rubber pad, it can generate an inward contraction deformation, so that the force required for the adjustment action of the steam pipe is smaller, facilitating the angle adjustment of the steam pipe and improving the user experience.

[0010] According to the above solution, the ball head structure includes a first hemispherical body and a second hemispherical body. The first hemispherical body and the second hemispherical body symmetrically clamp the steam pipe, and the first hemispherical body is fixedly connected to the second hemispherical body. The ball head structure adopts a split structure, that is, the first hemispherical body and the second hemispherical body are assembled to form the ball head structure, thus facilitating the installation of the ball head structure on the steam pipe. Of course, the ball head structure can also be provided on the steam pipe by a forming process.

[0011] According to the above solution, pipe grooves are provided on the mating surfaces of the first hemispherical body and the second hemispherical body, and the steam pipe passes through between the two pipe grooves; a positioning groove is provided on the outer wall of the steam pipe, and a half-moon buckle is protrudingly provided on the inner wall of the pipe groove. The half-moon buckle is embedded in the positioning groove. The two pipe grooves are paired to form a hole adapted to the steam pipe, so that the first hemispherical body and the second hemispherical body are paired and clamped on the steam pipe. Further, after the positioning groove and the half-moon buckle are snap-connected, the ball head structure and the steam pipe form an axial paired connection.

[0012] According to the above solution, a plurality of fixing columns are provided on the inner lining bracket, and the upper cover is fixed on the inner lining bracket by bolt connection to the fixing columns. The bolt and the fixing column fix the upper cover on the inner lining bracket. By adjusting the tightness of the bolt, the upper cover presses the rubber pad, thereby changing the tightness of the gland on the ball head structure.

[0013] According to the above solution, a bean box assembly, a control panel, a bean grinding assembly, a water tank assembly, a brewing system and a steam system are provided on the coffee machine main body, and the steam system includes a steam pipe.

[0014] In a steam pipe fixing structure of the present utility model, the upper cover is connected to the inner lining bracket to encapsulate the clamping assembly therebetween. An action cavity is formed between the clamping assembly and the inner lining bracket. The movable clamping assembly enables the action cavity to deform, thereby providing an appropriate clamping force to the ball head structure. The ball head structure can easily rotate in the action cavity to change the angle of the steam pipe, facilitating the operation of the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions of the present utility model will be described below in conjunction with the accompanying drawings and embodiments.

[0026] Such as Figures 1-6As shown in the figure, a steam pipe fixing structure of the present utility model includes a coffee machine main body 1 and a steam pipe 2. The steam pipe 2 is rotatably installed on the coffee machine main body 1 through a supporting component. The supporting component includes a lining bracket 3, a clamping component, and an upper cover 4. The clamping component is movably arranged between the upper cover 4 and the lining bracket 3. The upper cover 4 is fixedly connected to the lining bracket 3, so that an action cavity 31 is formed between the clamping component and the lining bracket 3. A ball head structure 21 is arranged on the steam pipe 2, and the ball head structure 21 is rotatably arranged in the action cavity 31. The supporting component is used to install the steam pipe 2 on the coffee machine main body 1, and the steam pipe 2 is rotatably connected to the coffee machine main body 1, so that the angle of the steam pipe 2 can be adjusted. Specifically, the clamping component is movably arranged between the upper cover 4 and the lining bracket 3, and the action of the clamping component can change the space size of the action cavity 31, so that the ball head structure 21 can rotate more smoothly in the action cavity 31. In particular, the upper cover 4 encapsulates the clamping component in the upper part of the action cavity 31. When there is no external force to push the steam pipe 2, the clamping component cooperates with the lining bracket 3, and the clamping component provides an appropriate clamping force to clamp the ball head structure 21 to prevent the steam pipe 2 from swinging.

[0027] The clamping component includes a gland 41 and a rubber pad 42. The upper cover 4, the rubber pad 42, and the gland 41 are stacked on the lining bracket 3 from top to bottom in sequence, and the action cavity 31 is formed between the gland 41 and the lining bracket 3. The lower outer edge of the ball head structure 21 is in contact connection with the lining bracket 3, and the gland 41 is in contact connection with the upper outer edge of the ball head structure 21. Further, after the upper cover 4 is fixed to the lining bracket 3, the gland 41 and the lining bracket 3 are paired to form the action cavity 31, and the ball head structure 21 can rotate in the action cavity 31. Of course, the upper cover 4 provides a pressure to the gland 41 through the rubber pad 42, so that the gland 41 and the lining bracket 3 cooperate to clamp the ball head structure 21, and the frictional force generated by the gland 41 and the lining bracket 3 can prevent the ball head structure 21 from rotating. When it is necessary to adjust the angle of the steam pipe 2, only the pressure generated by the rubber pad 42 needs to be overcome, so that the gland 41 moves upward to increase the space of the action cavity 31, so that the ball head structure 21 can rotate flexibly in the action cavity 31, which is convenient for users to operate and improves the use experience.

[0028] A through hole 43 is provided inside the upper cover 4, and the through hole 43 penetrates through the upper and lower ends of the upper cover 4; the gland 41 is arranged inside the lower port of the upper cover 4, a snap ring 44 is arranged inside the upper port of the upper cover 4, and the rubber gasket 42 is clamped on the snap ring 44 so as to be in top contact connection with the gland 41. The through hole 43 is used to accommodate the gland 41 and the rubber gasket 42, so that the snap ring 44 touches the rubber gasket 42, the rubber gasket 42 touches the gland 41, and the gland 41 clamps the ball head structure 21. When the steam pipe 2 rotates, the gland 41 is subjected to the pressure of the ball head structure 21, overcoming the pressure of the rubber gasket 42 to cause it to deform, and the gland 41 moves upward along the through hole 43, thereby increasing the space of the action cavity 31, so that the ball head structure 21 can rotate flexibly inside the action cavity 31.

[0029] A clamping groove 45 is provided on the snap ring 44, the rubber gasket 42 is in a flared shape, the large mouth end of the rubber gasket 42 is clamped to the clamping groove 45, and the small mouth end of the rubber gasket 42 is in top contact connection with the gland 41. The clamping groove 45 can fix the rubber gasket 42 on the snap ring 44, preventing the rubber gasket 42 from detaching between the snap ring 44 and the gland 41 when deforming. Further, the small mouth end of the flared rubber gasket 42 abuts against the gland 41, and the rubber gasket 42 can generate an inward contraction deformation with a smaller pressure at the lower end, so that the force required for the adjustment action of the steam pipe 2 is smaller, facilitating the angle adjustment of the steam pipe 2 and improving the user experience.

[0030] The ball head structure 21 includes a first hemispherical body 22 and a second hemispherical body 23. The first hemispherical body 22 and the second hemispherical body 23 symmetrically clamp the steam pipe 2, and the first hemispherical body 22 is fixedly connected to the second hemispherical body 23. The ball head structure 21 adopts a split structure, that is, the first hemispherical body 22 and the second hemispherical body 23 are assembled to form the ball head structure 21, so as to facilitate the installation of the ball head structure 21 on the steam pipe 2. Of course, the ball head structure 21 can also be provided on the steam pipe 2 by a forming process.

[0031] Tube grooves 24 are provided on the mating surfaces of the first hemispherical body 22 and the second hemispherical body 23, and the steam pipe 2 passes through between the two tube grooves 24; a positioning groove 25 is provided on the outer wall of the steam pipe 2, and a half-moon buckle 26 is convexly provided on the inner wall of the tube groove 24, and the half-moon buckle 26 is embedded in the positioning groove 25. The two tube grooves 24 are paired to form a hole adapted to the steam pipe 2, so that the first hemispherical body 22 and the second hemispherical body 23 are paired and clamped on the steam pipe 2. Further, after the positioning groove 25 and the half-moon buckle 26 are snap-connected, the ball head structure 21 and the steam pipe 2 form an axial paired connection.

[0032] A plurality of fixing columns 32 are provided on the inner lining bracket 3, and the upper cover 4 is fixed on the inner lining bracket 3 by bolt connection with the fixing columns 32. The bolts and the fixing columns 32 fix the upper cover 4 on the inner lining bracket 3.
