DETAILED DESCRIPTION

[0029] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] See also Figure 1-Figure 8 The utility model discloses a steam pipe 30 assembly, including a connection seat 20 and a steam pipe 30; a connection cavity 25 and a first connection portion are provided in the connection seat 20, and the first connection portion is provided at the side of the connection seat 20. Specifically, a second connection portion is provided on the steam pipe 30, and the steam pipe 30 is connected to the connection cavity 25 of the connection seat 20. After the steam pipe 30 is connected to the connection cavity 25, the second connection portion on the steam pipe 30 can correspond to the first connection portion, and then the first connection portion can be detachably connected to the second connection portion from the side, so that the steam pipe 30 is connected to or disconnected from the connection seat 20.

[0033] On the basis of the above structure, when the steam pipe 30 assembly of the utility model is used, the steam pipe 30 assembly can be applied to beverage making equipment such as coffee machines, beverage machines, and milk frothers that require the use of steam to make milk froth. Specifically, this embodiment is described by taking the application of the steam pipe 30 assembly to a coffee machine as an example:

[0034] When assembling the steam pipe 30 assembly, the end of the steam pipe 30 can be first connected to the connection cavity 25 of the connection seat 20, and the second connection portion on the steam pipe 30 can be connected to the first connection portion on the connection seat 20, so that the steam pipe 30 can be assembled with the connection seat 20, and then the connection seat 20 can be assembled with the main structure of the coffee machine. The steam pipe 30 can be connected to the steam conduit inside the main body of the coffee machine, so that steam can be introduced into the steam pipe 30 through the steam conduit, and the steam nozzle at the end of the steam pipe 30 is used to produce milk foam.

[0035] It should be noted that, since the connection seat 20 and the steam pipe 30 are detachably connected by the first connection part and the second connection part, and the first connection part is arranged on the side of the connection seat 20, when the steam pipe 30 needs to be disassembled and cleaned, it can be operated from the side to achieve the connection or disconnection of the first connection part and the second connection part, so that the steam pipe 30 and the connection seat 20 can be disassembled for cleaning, which is convenient for maintenance, and after cleaning, the first connection part and the second connection part can be connected from the side to achieve the connection of the steam pipe 30 and the connection seat 20, and complete the assembly of the steam pipe assembly. At the same time, the side operation of this embodiment is used to realize the disassembly and assembly of the connection seat 20 and the steam pipe 30. Compared with the traditional top or bottom operation fixation, on the one hand, it can provide more operating space for users or disassembly and assembly personnel, which is conducive to disassembly and assembly, and on the other hand, it can provide avoidance space for the design of other structural parts of the steam pipe assembly, which is more conducive to optimizing and improving the structural performance of the steam pipe assembly.

[0036] Furthermore, in this embodiment, a clamping member 21 and a connection groove 22 may be provided on the side of the connection seat 20, and the connection groove 22 may penetrate into the connection cavity 25, and one end of the clamping member 21 may be inserted into the connection cavity 25 through the connection groove 22 to form a clamping end. A clamping groove 31 may be provided on the outer wall of the steam pipe 30, so that when the steam pipe 30 and the connection seat 20 are assembled, the steam pipe 30 may be connected to the active cavity of the connection seat 20, and the connection groove 31 on the steam pipe 30 may correspond to the connection groove 22 of the connection seat 20, so that after the clamping member 21 is inserted into the connection groove 22, the clamping end may be clamped into the connection groove 31.

[0037] In this embodiment, the steam pipe 30 and the connection seat 20 are assembled by first inserting the steam pipe 30 into the connection cavity 25 of the connection seat 20, and then inserting the clamping member 21 into the connection cavity 25 through the connection groove 22 on the side of the connection seat 20 to clamp the steam pipe 30. That is, before assembly, the clamping member 21 structure is not set inside the movable cavity, which will not cause resistance to the up and down assembly movement of the steam pipe 30, and the assembly process is smoother. In addition, since the clamping member 21 is installed on the side to form a clamping end for clamping assembly, it is more convenient to assemble on the side. Similarly, when disassembling, the clamping member 21 is directly operated on the side of the connection seat 20, and the clamping member 21 is taken out from the side, and the clamping end of the clamping member 21 is withdrawn from the clamping groove 31 of the steam pipe 30, which is convenient for disassembly.

[0038] Furthermore, the above-mentioned clamping member 21 includes a connecting arm 211 and two clamping arms 212. The two clamping arms 212 are connected to both sides of the connecting arm 211, that is, the two clamping arms 212 are spaced apart from each other by the connecting arm 211, so that the two clamping arms 212 have a tension for pressing inward. During assembly, the two clamping arms 212 extend through the through-connection groove 22 and clamp to the clamping groove 31, so that the connecting arm 211 is located in the through-connection groove 22. Based on this structure, the clamping arms 212 are formed as clamping ends. In this way, the interval between the two clamping arms 212 can be set to be greater than or slightly greater than the inner diameter of the connecting groove 22. After the two clamping arms 212 are extended into the connecting groove 22, the two clamping arms 212 are pressed by the groove walls on both sides of the connecting groove 22, so that the clamping arms 212 can be squeezed inward. After extending into the connecting cavity 25, the two clamping arms 212 are respectively pressed by the inner walls of the connecting cavity 25, maintain the returned state, and are clamped in the clamping groove 31, so that the steam pipe 30 and the connecting seat 20 can be assembled and tightened.

[0039] Of course, when assembling or disassembling the clamping member 21 , the connecting arm 211 may be held for operation, which makes assembly and disassembly convenient.

[0040] More specifically, the two ends of the connecting seat 20 away from the connecting groove 22 are provided with positioning holes 23, and the part of the clamping arm 212 extending into the connecting cavity 25 is clamped to the clamping groove 31. In addition, a positioning portion is provided at the end of the clamping arm 212, and the positioning portion at the end of the clamping arm 212 extends through the clamping groove 31 and is clamped to the positioning hole 23.

[0041] Based on this structure, after the two clamping arms 212 are installed in the connection cavity 25, the part clamped to the clamping groove 31 in the steam pipe 30 is restricted by the inner wall of the connection cavity 25 to maintain the clamped state. In this embodiment, the positioning part at the end of the clamping arm 212 extends out and is positioned from the positioning hole 23 on the other side of the connecting seat 20, so that one end of the clamping arm 212 is limited by the connection groove 22, the part of the clamping arm 212 extending into the connection cavity 25 is clamped to the clamping groove 31, and the other end of the clamping arm 212 is limited by the positioning hole 23, so that the same clamping arm 212 is assembled at three points, and the assembled structure formed is more stable.

[0042] Of course, it should be noted that the above-mentioned clamping groove 31 can be selected as an annular clamping groove, that is, the two clamping arms 212 can be clamped into the corresponding two sides of the same annular clamping groove on the steam pipe 30 from the two sides of the connecting cavity 25. In other cases, the clamping groove 31 can be respectively provided on both sides of the steam pipe 30 corresponding to the clamping arms 212, and during assembly, the clamping arms 212 on both sides can be clamped and assembled one by one.

[0043] Furthermore, in order to prevent the steam pipe 30 from rotating relative to the connecting seat 20 after being assembled with the connecting seat 20, a first limiting plane 32 can also be provided on the outer wall of the steam pipe 30 in the present application, and a second limiting plane 251 is correspondingly provided on the inner wall of the connecting cavity 25. The first limiting plane 32 is used to abut against the second limiting plane 251 after the steam pipe 30 is connected to the connecting cavity 25 to prevent the steam pipe 30 and the connecting seat 20 from rotating.

[0044] If the arc outer circumference of the steam pipe 30 is directly connected and assembled with the arc inner circumference of the connection cavity 25, even if the clamping piece 21 is assembled, the steam pipe 30 is easy to rotate relative to the connection seat 20 under the action of steam pressure or external force, which will cause the structure of the clamping piece 21 to loosen and become unstable. Therefore, the first limiting plane 32 of the steam pipe 30 and the second limiting plane 251 of the connection seat 20 can be used, so that the steam pipe 30 and the connection seat 20 can be partially matched at the plane abutment, which is not easy to rotate, thereby improving the reliability of use after assembly.

[0045] In addition, the first limiting plane 32 and the second limiting plane 251 can be arranged correspondingly during assembly to achieve positioning assembly.

[0046] Furthermore, in this embodiment, in order to facilitate the assembly of the steam pipe assembly, a mounting shell 10 can be further included, and the mounting shell 10 can be assembled to the coffee machine host. Specifically, a movable cavity is provided in the mounting shell 10, and a first limiting portion 113 is provided in the movable cavity. The connecting seat 20 can be movably connected in the movable cavity of the mounting shell 10, and the second limiting portion can abut against the first limiting portion 113 when the connecting seat 20 rotates, so as to limit the rotation range of the connecting seat 20.

[0047] Since the steam pipe 30 needs to be rotated when making milk froth, the steam pipe 30 can be held by hand so that the connection seat 20 on the steam pipe 30 can be rotated relative to the movable cavity in the mounting housing 10, so that the steam pipe 30 can be rotated to different angles for making milk froth. However, if the steam pipe 30 is rotated in the same direction all the time, the internal pipe of the steam pipe 30 will be twisted and blocked, thereby affecting the amount of steam output.

[0048] Therefore, in the present embodiment, the first limiting portion 113 on the connecting seat 20 on the steam pipe 30 is abutted against the second limiting portion in the movable cavity of the mounting shell 10 to achieve limiting abutment. In this way, when the steam pipe 30 rotates in one direction, it will abut against the second limiting portion to achieve rotation limiting. At this time, the steam pipe 30 can be rotated in the opposite direction to prevent the steam pipe 30 from twisting, winding, knotting, etc. caused by a 360-degree rotation, reduce the situation of insufficient steam or non-extraction of steam due to blockage of the steam pipe 30, and improve the efficiency and effect of coffee milk foam making.

[0049] Specifically, a limiting rib 24 may be convexly provided on the outer wall of the connection seat 20, and a limiting groove 112 may be provided on the inner peripheral wall of the active cavity, and the limiting groove 112 extends along the rotation direction of the connection seat 20. During assembly, the connection seat 20 is connected to the active cavity of the mounting housing 10, and the connection seat 20 is inserted through the limiting groove 112, that is, the limiting rib 24 is located in the limiting groove 112. Based on this structure, the end walls of the limiting groove 112 on both sides form the first limiting portion 113, and the limiting rib 24 forms the second limiting portion.

[0050] In this way, when the steam pipe 30 rotates, the connecting seat 20 can be driven to rotate together, and the limiting rib 24 on the connecting seat 20 can rotate in the limiting groove 112. When the steam pipe 30 rotates in one direction, it can abut against one of the side walls of the limiting groove 112 to prevent it from further rotation. Thereafter, the steam pipe 30 rotates in the opposite direction, so that when it abuts against the other side wall of the limiting groove 112 during the reverse rotation, it can also be limited. In this embodiment, the extension angle of the limiting groove 112 in the rotation direction is the rotation range of the steam pipe 30.

[0051] Of course, the rotation limitation of the steam pipe 30 can also be achieved by providing a protruding rib on the inner wall of the active cavity and correspondingly providing a limiting groove 112 on the outer wall of the connecting seat 20, and also forming a first limiting portion 113 and a second limiting portion.

[0052] On the basis of the structure of the limit groove 112 provided in the movable cavity, two first limit parts 113 are formed by the two side walls of the limit groove 112, so that the second limit part moves between the first limit parts 113, and the rotation range of the steam pipe 30 is relatively small. Of course, a protruding rib can also be provided on the inner wall of the movable cavity, and a protruding rib can be provided on the outer side of the connecting seat 20 correspondingly, so that when the connecting seat 20 rotates, the protruding ribs can also abut against each other to achieve one-way positioning, thereby preventing the steam pipe 30 from rotating 360 degrees.

[0053] Furthermore, in this embodiment, the steam pipe assembly can be assembled to the coffee machine body by setting a mounting shell 10, so that the steam pipe can be easily assembled with the mounting shell by the connecting seat. The mounting shell 10 includes a mounting base 11, a pressing plate 12 and a connecting mechanism, a first mounting groove 111 is provided on the mounting base 11, and a second mounting groove 121 is correspondingly provided on the pressing plate 12, and the pressing plate 12 is connected to the mounting base 11 through the connecting mechanism, so that the pressing plate 12 floats up and down relative to the mounting base, and after the pressing plate 12 and the mounting base 11 are assembled, the second mounting groove 121 and the first mounting groove 111 are correspondingly matched to form an active cavity, and the connecting seat can be assembled into the active cavity formed by the mounting base and the pressing plate.

[0054] In this way, since the above-mentioned mounting shell 10 is formed by connecting the mounting base 11 and the pressure plate 12 with a connecting mechanism, when assembling the steam pipe 30 component, the steam pipe 30 and the connecting seat 20 can be assembled externally, and the mounting base 11 can be assembled on the coffee machine body by bolts, screws and other structures. At this time, the first mounting groove 111 on the mounting base 11 is exposed, and the outer diameter of the connecting seat 20 outside the steam pipe 30 is larger than the steam pipe 30. The steam pipe 30 can be inserted into the first mounting groove 111, and then the connecting seat 20 is located behind the first mounting groove 111, and then the pressure plate 12 is connected to the mounting base 11 through the connecting mechanism, so that the connecting seat 20 can be connected to the second mounting groove of the pressure plate 12 and the first mounting groove 111 of the mounting base 11, that is, the connecting seat 20 is connected to the connecting cavity 25, which is convenient for assembly.

[0055] It should be noted that, since the steam pipe 30 will swing up and down when making milk foam, in this embodiment, the connecting seat 20 in the movable chamber is designed with space for up and down rotation, and the pressing plate 12 and the mounting base 11 are connected by a connecting mechanism, so that the pressing plate 12 has space to float up and down relative to the mounting base 11 after the connection, which facilitates the up and down swinging of the connecting seat 20 inside and reduces the possibility of jamming.

[0056] Furthermore, the above-mentioned connecting mechanism includes an adjusting member 13 and an elastic member 14, one end of the adjusting member 13 is an adjusting end 131, and one end of the adjusting member 13 is a connecting end 132, the connecting end 132 passes through the pressure plate 12 and is connected to the mounting base 11, and the elastic member 14 is clamped between the adjusting end 131 and the pressure plate 12, so that the pressure plate 12 can be connected to the mounting base 11 through the adjusting member 13, and the elastic member 14 between the two can provide a certain pre-tightening force, so that there is a floating space between the pressure plate 12 and the mounting base 11, which is convenient for the connecting seat 20 to move up and down in the active cavity and reduce the situation of getting stuck.

[0057] The depth of the connecting end 132 of the adjusting member 13 inserted into the mounting base 11 can adjust the pressure of the adjusting end 131 pressed against the elastic component 14, so that the compression amount of the elastic component 14 can be adjusted, thereby adjusting the up and down floating space of the above-mentioned pressure plate 12, and the freedom of movement of the connecting seat 20 in the movable cavity can also be adjusted accordingly.

[0058] Furthermore, in order to facilitate assembly, a positioning column 114 can be provided on the mounting base 11, and a corresponding positioning groove 122 can be provided on the pressure plate 12, the positioning column 114 is passed through the positioning groove 122, and the elastic component 14 is provided in the positioning groove 122 and is mounted on the positioning column 114; the connecting end 132 is connected to the positioning column 114 so that the adjusting end 131 is pressed against the elastic component 14.

[0059] In this way, the positioning column 114 can be inserted into the positioning groove 122 of the pressure plate 12 to achieve pre-positioning, and then the elastic component 14 can be inserted into the positioning column 114 of the positioning groove 122. Thereafter, the connecting end 132 of the adjusting component 13 is connected to the positioning column 114, and the adjusting end 131 of the adjusting component 13 can be pressed against the elastic component 14 to achieve elastic assembly.

[0060] Of course, the above-mentioned adjustment member 13 can be a structure such as a bolt or a screw, and the head of the bolt or screw can be formed as an adjustment end 131, which presses the elastic component 14. The compression amount of the elastic component 14 can be adjusted by spirally rotating the bolt or screw structure, which is convenient for adjustment.

[0061] In addition, it should be noted that an elastic rubber block or other structure can be connected between the pressure plate 12 and the mounting base 11, and then the pressure plate 12 and the mounting base 11 can be directly assembled with a connecting structure so that the two can maintain space for floating up and down after assembly. Of course, the assembly can also be achieved through relatively sliding sliding columns and sliding holes, as long as there is space between the two for sliding up and down.

[0062] Of course, it should also be noted that the floating space between the pressing plate 12 and the mounting base 11 only needs to be large enough for the connecting seat 20 to rotate up and down, so as to prevent the connecting seat 20 from being detached or excessively rotated.

[0063] Furthermore, in order to improve the stability of assembly, a plurality of positioning columns 114 can be provided on the mounting base, and a plurality of positioning grooves 122 can be provided on the pressure plate 12 accordingly. During assembly, the plurality of positioning columns 114 are connected to the plurality of positioning grooves 122 one by one. In this way, the assembly between the pressure plate 12 and the mounting base 11 can be achieved by positioning assembly with the plurality of positioning columns 114 and the plurality of positioning grooves 122, and the plurality of positioning columns 114 and the plurality of positioning grooves 122 are distributed on the periphery of the active cavity, and a plurality of connecting mechanisms are connected in the corresponding positioning grooves 122. The elastic stress provided by the elastic components 14 of each connecting mechanism can be distributed evenly, so that the assembly structure is more stable.

[0064] Furthermore, in the present embodiment, the connecting seat 20 is a ball head, and the movable cavity is a ball head cavity. Thus, the ball head can be rotated or swung up and down in the ball head cavity more flexibly and is less likely to get stuck.

[0067] In the present embodiment, since the connection seat 20 and the steam pipe 30 are detachably connected by the first connection part and the second connection part, and the first connection part is arranged on the side of the connection seat 20, when the steam pipe 30 needs to be disassembled and cleaned, the first connection part and the second connection part can be separated from the side to realize the disassembly of the connection seat 20 and the steam pipe 30.
