For a better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model.

In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, only for convenience in describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or elements to be referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Referring to fig. 1-8, the utility model discloses a steam bar, which comprises a steam conduit 40 and a steam nozzle 10, wherein a first positioning piece is arranged on the steam conduit 40, and a cavity is arranged in the steam nozzle 10. Specifically, the steam nozzle 10 is provided with an inlet end 11 and an outlet end 12, the inlet end 11 is provided with a steam inlet, and the outlet end 12 is provided with a steam outlet.

The steam conduit 40 is provided in the cavity and is in sealing engagement with the inner wall of the cavity, e.g. when assembled, the steam conduit 40 is extended into the cavity of the steam nozzle 10 through the steam inlet of the introduction end 11, and the steam conduit 40 is in sealing engagement with the inner wall of the cavity which is assembled to the steam nozzle 10. A second positioning member is provided in the cavity, and is positioned to cooperate with the first positioning member to prevent the steam conduit 40 from moving up and down the cavity after the steam conduit 40 is installed in the cavity. On the basis of the structure, when the steam rod is used, the steam rod can be applied to manufacturing equipment such as a drink machine, a coffee machine, a milk foam machine and the like, and when the steam rod is assembled, the steam rod is assembled on a machine body, so that the steam conduit 40 is communicated with an outlet of a steam generating device in the machine body, steam can be led into a cavity through the steam conduit 40, and steam entering the cavity can be led out through a steam outlet of the steam nozzle 10 and used for heating milk in a drink to foam or heating the drink. It should be noted that, because in the steam introducing process, steam enters into the cavity, the outer wall of the steam conduit 40 is assembled with the inner wall of the cavity in a sealing fit manner, after the steam is led out from the steam conduit 40, the steam in the cavity can flow back to the upper side of the steam conduit 40, or the steam in the steam conduit 40 can move up and down due to unstable air pressure of the steam, so that the steam conduit 40 needs to have certain assembling stability in the steam nozzle 10, and the vertical movement is prevented.

Therefore, in this embodiment, after the steam conduit 40 is assembled to the cavity, the second positioning member in the cavity may be in positioning fit with the first positioning member on the steam conduit 40, so that the first positioning member and the second positioning member may prevent the steam conduit 40 from moving in the cavity of the steam nozzle 10 during use, that is, the movement of the steam conduit is positioned by the cooperation of the first positioning member and the second positioning member, so that the steam conduit is effectively prevented from being separated due to the movement, thereby reducing the steam backflow caused by the separation of the steam conduit 40 and preventing the user from being scalded.

It should be noted that, the steam conduit 40 may be a teflon tube in the prior art, which has high temperature resistance, aging resistance, and can guide steam flow and improve the service life of the conduit. The sealing fit between the steam conduit and the inner wall of the cavity of the steam nozzle can be realized in a sealing ring, a sealing ring or filling sealing glue, and the like, and the steam conduit and the inner wall of the cavity of the steam nozzle are specifically selected according to actual needs. The positioning and matching of the first positioning piece and the second positioning piece can be realized by adopting the modes of abutting, clamping, buckling and the like, and the embodiment is not particularly limited.

Of course, the steam conduit may extend into the cavity of the steam nozzle through the introduction end, or may extend into the steam nozzle through another position of the steam nozzle, so that the steam conduit may extend into the cavity to achieve steam introduction.

Further, a guide 30 can be arranged in the cavity, and after the guide is positioned in the cavity, part of the outer wall of the guide, which is positioned at the inlet of the steam nozzle, can be in sealing fit with the inner wall of the cavity. In addition, a steam introducing cavity 31 is arranged in the guide member, one end of the steam introducing cavity 31 is communicated with a steam inlet, the other end of the steam introducing cavity 31 is communicated with a steam nozzle leading-out end part of the cavity, and the steam conduit 40 extends into the steam introducing cavity 31 through the steam inlet; the second positioning member extends into the steam introduction chamber 31 and abuts against the first positioning member.

In this way, the inner wall of the outer cavity of the guide member 30 can be hermetically matched, the steam conduit 40 extends into the steam introducing cavity of the guide member 30 through the steam inlet of the steam nozzle 10, the steam can be introduced into the steam introducing cavity 31, then is introduced into the steam nozzle 10 through the steam introducing cavity 31, and is led out through the steam outlet of the steam nozzle 10.

On the basis of the structure, when the steam guide pipe 40 is assembled, the steam guide pipe and the steam guide cavity 31 of the guide piece can be assembled outside the steam nozzle 10, then the first positioning piece on the steam guide pipe 40 is positioned in the steam guide cavity 31, then the second positioning piece stretches into the steam guide cavity of the guide piece 30, the second positioning piece can be assembled in the guide piece 30 in a limiting mode, then the sealing piece is assembled outside the guide piece 30 or is assembled in the cavity of the steam nozzle 10, and therefore the guide piece 30 can be assembled in a sealing mode at the guide end 11 of the steam nozzle 10 after being assembled in the cavity of the steam nozzle 10, and the assembly is more convenient.

It should be noted that, because the installation of the steam conduit is convenient, and the steam conduit is generally in a hose structure, if the steam conduit is directly assembled into the steam nozzle, the steam conduit is not supported by the bracket, and then the condition of left-right swing or movement in the steam guiding process can occur, so in the embodiment, the steam conduit is installed into the guide piece serving as the bracket, then the second positioning piece is matched with the first positioning piece on the steam conduit, after the positioning of the steam conduit and the guide piece is realized, the guide piece is installed into the steam nozzle integrally, so that the steam conduit is assembled stably, and the steam guiding is conveniently and stably guided in the later period.

Of course, the second positioning member may extend from the guide member to the steam introducing chamber, and may be in a completely extended state or a partially extended state, so long as it is capable of achieving positioning fit with the first positioning member.

In this embodiment, the first positioning member and the second positioning member are positioned in a manner of abutting the positioning ring and the clamping ring, and the clamping ring is clamped into the guiding member in a clamping manner and extends into the steam guiding cavity after being clamped.

Specifically, the clamping port 37 may be provided on the guide member 30, the second positioning member is a clamping ring 60, the first positioning member is a positioning ring 41 disposed outside the steam conduit 40, during assembly, the steam conduit 40 extends into the steam introducing cavity 31 of the guide member 30, the positioning ring 41 outside the steam conduit 40 is located behind the steam introducing cavity 31, and then the clamping ring 60 is clamped into the steam introducing cavity 31 via the clamping port 37 and abuts against the positioning ring 41, so that the position of the clamping ring 60 is limited by the clamping port 37, and the clamping ring 60 abuts against the positioning ring 41 after extending into the steam conduit 40, thereby preventing the steam conduit 40 from moving up and down and preventing the situation of detachment.

Of course, the clamping ring structure can also be directly formed in the guide piece in an integrated manner, and after the steam guide pipe stretches into the steam guide cavity, the clamping ring structure is positioned above the positioning ring of the steam guide pipe, so that the supporting and the anti-falling are realized.

Specifically, the clamping ports 37 may be disposed on two sides of the guide member 30, when the clamping ring 60 is assembled, the clamping ring 60 may be inserted into the steam guiding cavity 31 through the clamping port 37 on one side of the guide member 30, then the clamping ring 60 is inserted into the outer surface of the steam conduit 40 and then sleeved with the outer surface of the steam conduit 40, and then the clamping ring 60 may be inserted into the clamping port 37 on the other side, so that after the clamping ring 60 is clamped outside the steam conduit 40, the clamping ports 37 on two sides of the clamping ring 60 may be correspondingly positioned for limiting, thereby effectively reducing loosening of the clamping ring 60 after assembly.

Of course, when the clamping port 37 is provided on one side, a clamping groove structure may be provided on the inner wall of the steam introduction chamber 31 of the guide member, so that the clamping arm structure of the clamping ring 60 may extend into the clamping groove after extending into and clamping the outer peripheral wall of the steam conduit 40, and the upper and lower positions of the clamping ring 60 may be limited.

Besides, the first positioning member and the second positioning member can be realized by adopting the structure of the snap ring 60 and the positioning ring 41, or can be realized by arranging a positioning boss structure outside the steam conduit 40 and then arranging a positioning boss structure inside the guide member 30 or directly in the cavity so as to clamp the positioning boss into the positioning groove to realize up-down positioning.

Further, a sealing pad 42 may be disposed on the outer wall of the steam conduit 40, and the sealing pad is in sealing fit with the interior of the steam introducing cavity, and the second positioning member abuts against the upper portion of the first positioning member to prevent the steam conduit from being separated from the cavity, where the sealing pad is located below the first positioning member.

The sealing pad 42 is located below the first positioning member and is in sealing fit with the inner wall of the steam introducing cavity 31, that is, after the steam conduit 40 and the steam introducing cavity 31 of the guiding member 30 are positioned and assembled by the second positioning member and the first positioning member, the sealing pad 42 can be sleeved below the steam conduit 40 and is used for sealing and positioning the ring below the first positioning member.

First, the gasket 42 is generally made of silica gel or rubber material, so that sealing can be achieved after the gasket is assembled to the steam conduit 40, and contact friction force of the steam conduit 40 after the gasket is assembled to the steam introducing cavity 31 of the guide 30 can be increased, and the friction force can provide a certain resistance to prevent the steam conduit 40 from moving up and down.

In addition, if the sealing gasket 42 is disposed above the positioning ring 41, the steam backflow will first pass through the assembly gap between the positioning ring 41 and the clamping ring 60, and after long-term use, the clamping ring 60 or the positioning ring 41 will corrode, so in this embodiment, since the sealing gasket 42 is disposed below the positioning ring 41, the sealing gasket 42 is disposed below the joint of the positioning ring 41 and the clamping ring 60, when the steam backflow is blocked by the sealing gasket 42, the steam backflow is reduced to enter the assembly gap between the positioning ring 41 and the clamping ring 60, and thus the service lives of the clamping ring 60 and the positioning ring 41 can be prolonged.

Of course, in the case where the first positioning member and the second positioning member have other structures, the gasket 42 is only required to be disposed below the fitting gap between the two members.

Further, the steam rod is further provided with a connecting pipe 2, specifically, a first thread structure 201 is arranged on the inner wall of the connecting pipe 2, and a second thread structure 202 is arranged on the outer wall of the connecting pipe 2, that is, the inner and outer sides of the connecting pipe 2 are respectively provided with a thread structure. A third thread structure 13 is provided corresponding to the inner wall of the cavity at the lead-in end 11. On the basis of the structure provided with the guide 30, a mounting sleeve 35 is arranged outside the guide, and a fourth thread structure 351 is arranged on the outer surface of the mounting sleeve 35.

In this way, the connecting pipe 2 can be communicated with the export structure of the steam generating device in the machine body through the connecting pipe 2, the second thread structure 202 of the connecting pipe 2 can be in threaded connection with the third thread structure 13 of the internal cavity of the steam nozzle 10 through the lead-in end 11, so that the connecting pipe 2 and the third thread structure can be assembled by threads, the assembling and the disassembling can be conveniently realized by adopting the mode of the threaded assembling, in addition, after the threaded assembling, the connecting pipe 2 and the third thread structure are assembled by adopting the screw thread and the screw thread to limit, and only the connecting pipe 2 can move up and down when rotating, so that the connecting pipe is not easily influenced by internal steam to cause movement in the using process, and the steam using process is stable.

Meanwhile, after the connecting pipe 2 is assembled with the steam nozzle 10, the guide piece 30 in the cavity of the steam nozzle 10 can extend into the connecting pipe 2, so that the end part of the installation sleeve 35 of the guide piece 30 can also extend into the connecting pipe 2, the installation sleeve 35 is in threaded connection with the first threaded structure 201 of the connecting pipe 2 through the fourth threaded structure 351, and after the threaded assembly, the guide piece 30 is assembled and limited by adopting the screw teeth and the screw teeth, and only moves up and down when rotating, so that the position of the guide piece 30 is not easily influenced by internal steam to generate play in the using process, and the steam using process is stable.

The screw thread structure is arranged on the mounting sleeve, and then the mounting sleeve is assembled to the mounting sleeve which is provided with the screw thread structure by being independently processed compared with the mounting sleeve which is directly arranged on the guide piece, so that the mounting sleeve is used as an assembly foundation.

Further, in order to facilitate the disassembly and assembly of the mounting sleeve 35 and the guide 30, after the mounting sleeve 35 is assembled to the guide 30, the guide may be provided with a buckle 38, and a bayonet is correspondingly provided on the mounting sleeve 35, after the mounting sleeve 35 is mounted on the guide, the buckle 38 of the guide may be clamped into the bayonet of the mounting sleeve 35, so that the position of the mounting sleeve 35 can be positioned while the assembly is realized.

Further, in order to realize sealing after the connection pipe 2 is assembled with the steam nozzle 10, a first sealing ring is clamped between the second thread structure 201 and the third thread structure 13; the second sealing ring is clamped between the third thread structure 202 and the fourth thread structure 351, so that after the connecting pipe 2 and the steam nozzle 10 are assembled, the steam nozzle can be sealed by the first sealing ring and the second sealing ring, and the first sealing ring and the second sealing ring can be extruded and deformed when the threads rotate to form a larger sealing surface, so that the sealing effect is better.

Further, in this embodiment, the guiding member includes a first end and a second end, specifically, a portion near the leading-in end of the steam nozzle is taken as the first end, a portion near the leading-out end of the steam nozzle is taken as the second end, the steam leading-in cavity is disposed at the first end, the outer wall of the first end is in sealing fit with the inner wall, the outer wall of the second end and the inner wall of the cavity are spaced to form a steam runner 50, one end of the steam runner 50 is communicated with the steam leading-in cavity 31, and the other end of the steam runner 50 is communicated with the steam outlet; the second end is provided with a mounting cavity 32, a temperature detector 20 is arranged in the mounting cavity 32, and the temperature detector 20 penetrates out of the mounting cavity 32 and extends out of the leading-out end 12.

Because the temperature detector 20 can extend from the leading-out end 12 of the steam nozzle 10, the probe of the temperature detector can directly extend into the beverage to detect the temperature of the beverage, and the part of the temperature detector arranged in the steam nozzle avoids the steam flow path and is isolated from steam, so that the temperature detector 20 can not be influenced by the steam in the steam nozzle, and the temperature detected by the temperature detector 20 can directly control the temperature of the beverage, and thus the milk frothing temperature and the beverage temperature can be controlled.

The temperature detector 20 in this embodiment may be selected from a temperature sensor in the prior art or an NTC temperature control element in the prior art for detecting temperature.

On the basis of the structure, since the temperature detector 20 is mounted at the second end of the guide member 30 and is positioned in the mounting cavity 32 at the second end, and the steam enters the steam channel formed by the outer wall of the second end and the inner wall of the cavity at intervals after being led in through the steam leading-in cavity 31 at the first end, the steam channel surrounds the outer wall of the second end, namely, the steam is led out by the steam channel after being led in through the first end, so that the flow path of the steam avoids the temperature detector 20 mounted in the second end, the temperature detector 20 is not influenced by the steam flowing in the steam channel, and the temperature of the steam outlet is directly detected by the extending part, and the detection structure is more accurate.

In order to facilitate the installation of the temperature detector 20, the second end may be provided with a penetrating opening 36, and the penetrating opening 36 may allow the temperature detector 20 to penetrate into the installation cavity 32, and due to the arrangement of the penetrating opening 36, the second end may form a non-completely closed state, so that the second end is sleeved with the sealing sleeve 34, so that the sealing sleeve 34 may seal the entire second end after the temperature detector 20 is installed, and may completely block the temperature detector 20 in the second end from the steam flow channel 50, and may effectively block the steam temperature from flowing inwards, so that the temperature detector 20 may not be affected by the steam temperature in the steam flow channel 50.

In addition, in the case of the sealing sleeve 34, the sealing sleeve 34 can be sealed from the peripheral wall of the second end to the end face of the second end, then the temperature detector 20 can be extended from the sealing sleeve 34, and since the sealing sleeve 34 is made of elastic materials, the elastic sealing sleeve 34 can be deformed to seal the joint position between the temperature detector 20 and the sealing sleeve 34 after the temperature detector 20 is extended from the sealing sleeve 34, and the sealing performance is better.

It should be noted that, the sealing sleeve 34 may be made of a heat insulating material in the prior art, so that after the sealing sleeve 34 is installed at the second end, the heat insulating material can perform a heat insulating function, and effectively prevent the heat of steam from flowing into the installation cavity 32 inside the second end.

In the case of example 2,

A coffee machine comprises a coffee machine body and a steam rod in the embodiment 1, wherein a steam generating device is arranged in the coffee machine body, and the steam rod is connected with the steam generating device.

It should be noted that, because in the steam introducing process, steam enters into the cavity, the outer wall of the steam conduit 40 is assembled with the inner wall of the cavity in a sealing fit manner, after the steam is led out from the steam conduit 40, the steam in the cavity can flow back to the upper side of the steam conduit 40, or the steam in the steam conduit 40 can move up and down due to unstable air pressure of the steam, so that the steam conduit 40 needs to have certain assembling stability in the steam nozzle 10, and the vertical movement is prevented.

Therefore, in this embodiment, after the steam conduit 40 is assembled to the cavity, the second positioning member in the cavity may be matched with the first positioning member on the steam conduit 40, so that the first positioning member and the second positioning member may prevent the steam conduit 40 from moving in the cavity of the steam nozzle 10 during use, that is, the movement of the steam conduit is achieved by matching the first positioning member and the second positioning member, so that the steam conduit is effectively prevented from being separated due to movement, thereby reducing the steam backflow caused by separation of the steam conduit 40 and preventing scalding the user.

In addition, the steam bar in this embodiment is the same as that in embodiment 1, and other structures and action principles of the specific steam bar are the same as those in embodiment 1, and are not described in detail herein.
