Description

Technical Field

[0001] This utility model relates to the field of beverage machine nozzle technology, specifically a telescopic nozzle structure for a beverage machine. Background Technology

[0002] To accommodate cups of varying heights, current beverage machines typically fix the milk frothing nozzle to a height-adjustable slide. However, this existing structure suffers from three major drawbacks: First, current technology lacks damping, requiring operators to use screws or knobs to tighten and maintain the nozzle height. Second, the milk frothing module and lifting housing are often integrated or require the removal of multiple screws for separation, making routine cleaning and descaling time-consuming and labor-intensive, failing to meet the rapid maintenance needs of high-frequency commercial applications. Third, traditional milk frothing systems mix steam and milk through simple channels, resulting in uncontrollable flow rates and excessively fast milk flow, affecting the stability of continuous frothing. Therefore, there is an urgent need for a telescopic nozzle structure that allows for quick, one-handed lifting and positioning, one-button module removal, and flow control. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a telescopic dispensing nozzle structure for a beverage machine, which can solve the problems in the prior art.

[0004] This utility model is achieved through the following technical solution: A telescopic dispensing nozzle structure for a beverage machine, comprising a housing, wherein a lifting housing is slidably disposed within the housing, characterized in that a base plate is disposed at the bottom of the lifting housing via a snap-fit ​​assembly, a milk foam module is fixed on the base plate, a guide rail assembly is disposed between the lifting housing and the housing to limit the sliding of the lifting housing, and trapezoidal spring sheet assemblies are also disposed on the front and rear sides of the lifting housing to elastically abut against the inner wall of the housing to provide damping so that the lifting housing is held at a certain position after being extended or retracted.

[0005] A further technical solution includes a side plate fixedly mounted on the front side of the lifting box, and a sliding groove on each side of the box, wherein the side plate passes through the sliding groove and slides in a sliding engagement with the sliding groove.

[0006] In a further technical solution, the side plate has an L-shaped structure, and the flanged part of the sliding groove slides against the front side of the box.

[0007] A further technical solution includes a trapezoidal spring assembly comprising multiple opening slots fixed to the left and right sides of the lifting box, with multiple opening slots arranged in an upper and lower array, and a trapezoidal spring fixed in the opening slot. The trapezoidal spring includes a straight portion and a trapezoidal portion, with the trapezoidal portion protruding from the opening slot and elastically abutting against the left and right sides of the inner wall of the box, so that the lifting box has damping when it rises and falls.

[0008] A further technical solution includes a snap-fit ​​assembly comprising a snap-fit ​​groove disposed on the left and right end walls of the inner side of the lifting box, a first plate fixed on the top of the bottom plate on each side, a second plate fixed on the top of the first plate, a buckle fixed on one side of the second plate, and a third plate fixed on one side of the buckle, the buckle snapping into the snap-fit ​​groove.

[0009] A further technical solution includes a milk foam module comprising a discharge nozzle fixed to the bottom of the base plate, an injection block fixed to the top of the base plate, a mixer fixed to one side of the injection block, a steam pipe inserted into the mixer, and an annular groove liquid guiding column provided inside the injection block. The injection block, the annular groove liquid guiding column, the steam pipe, the mixer, and the discharge nozzle are connected in a manner.

[0010] A further technical solution includes an injection hole within the injection block and a liquid guiding cavity within the injection block, the liquid guiding cavity communicating with the injection hole. An annular groove liquid guiding column is inserted into the liquid guiding cavity. An inner hole is provided within the annular groove liquid guiding column, and a connecting hole is provided within the inner hole. An annular groove is provided on the outer surface of the annular groove liquid guiding column, and the annular groove communicating with the inner hole.

[0012] The beneficial effects of this utility model are as follows: First, by setting a snap-fit ​​component, the base plate and milk foam module can be easily removed from the bottom of the lifting box. By setting a guide rail component and a trapezoidal spring component, the lifting box can maintain a certain height under the damping action when adjusting the height up and down. After the lifting box is adjusted upward, a taller container can be placed on the lower side of the lifting box to avoid the taller container being unable to receive milk foam.

[0013] Second, the milk foam module utilizes the structural design of annular groove liquid guide column, inner hole, discharge nozzle and annular groove to control the milk flow rate. Furthermore, through the structure of mixing chamber, inlet hole, steam channel and outlet hole, steam directly acts on the milk to form milk foam. Then, as the steam continues to fall from the outlet hole, milk foam blockage is avoided and the flow is accelerated. Attached Figure Description

Detailed Implementation

[0016] like Figures 1-13 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1The projection relationship of the device itself is consistent in the up, down, left, right, front, and back directions. The telescopic dispensing nozzle structure for a beverage machine of this utility model includes a housing 11, a lifting housing 12 that is slidably disposed inside the housing 11, a base plate 13 that is disposed at the bottom of the lifting housing 12 through a snap-fit ​​assembly, a milk foam module that is fixed on the base plate 13, a guide rail assembly that is disposed between the lifting housing 12 and the housing 11 to limit the sliding of the lifting housing 12, and trapezoidal spring sheet assemblies that are disposed on the front and rear sides of the lifting housing 12 to elastically abut against the inner wall of the housing 11 to provide damping so that the lifting housing 12 is held in a certain position after being extended or retracted.

[0017] Advantageously, the guide rail assembly includes a side plate 42 fixedly disposed on the front side of the lifting box 12. The side plate 42 has an L-shaped structure. The box 11 is provided with a left and a right slide groove 41. The side plate 42 passes through the slide groove 41 and is slidably connected with the slide groove 41. The flanged part of the slide groove 41 slides against the front side of the box 11. The flange is used to limit the lifting of the lifting box 12, so that the side plate 42 slides in the slide groove 41.

[0018] Advantageously, the trapezoidal spring assembly includes multiple opening slots 43 fixed on the left and right sides of the lifting box 12. Multiple opening slots 43 are arranged in an array. A trapezoidal spring 44 is fixed in the opening slot 43. The trapezoidal spring 44 includes a straight part and a trapezoidal part. The trapezoidal part protrudes from the opening slot 43 and elastically abuts against the left and right sides of the inner wall of the box 11, so that the lifting box 12 has damping when it is raised and lowered.

[0019] Advantageously, the snap-fit ​​assembly includes a snap-fit ​​groove 54 disposed on the left and right end walls of the inner side of the lifting box 12. A first plate 51 is fixed on the top of the bottom plate 13 on the left and right. A second plate 55 is fixed on the top of the first plate 51. A buckle 52 is fixed on one side of the second plate 55. A third plate 53 is fixed on one side of the buckle 52. The buckle 52 snaps into the snap-fit ​​groove 54. By pressing the third plate 53 and moving it toward the first plate 51, the buckle 52 is disengaged from the snap-fit ​​groove 54. Then, the bottom plate 13 and the milk foam module on the bottom plate 13 are pulled downward from the lifting box 12, thus separating them from the lifting box 12.

[0020] Advantageously, the milk foam module includes a discharge nozzle 14 fixed to the bottom of the base plate 13, an injection block 27 fixed to the top of the base plate 13, a mixer 34 fixed to one side of the injection block 27, a steam pipe 36 inserted into the mixer 34, and an annular groove liquid guiding column 22 provided in the injection block 27. The injection block 27, the annular groove liquid guiding column 22, the steam pipe 36, the mixer 34 and the discharge nozzle 14 are connected. Milk is supplied from the injection block 27, and after being throttled by the annular groove liquid guiding column 22, it enters the mixer 34. Steam is introduced through the steam pipe 36 to form milk foam, which then flows out from the discharge nozzle 14.

[0021] Advantageously, the injection block 27 is provided with an injection hole 26 and a liquid guiding cavity 38, which is connected to the injection hole 26. The annular groove liquid guiding column 22 is inserted into the liquid guiding cavity 38. The annular groove liquid guiding column 22 is provided with an inner hole 23, and a connecting hole 24 is provided in the inner hole 23. The outer surface of the annular groove liquid guiding column 22 is provided with an annular groove 25, which is connected to the inner hole 23. The injection block 27 is also provided with an outlet hole 29, which is connected to the annular groove 25. Milk enters the liquid guiding cavity 38 from the injection hole 26, then enters the inner hole 23, overflows into the annular groove 25 after passing through the connecting hole 24, and then flows out from the outlet hole 29.

[0022] Advantageously, the mixer 34 is provided with an inlet hole 21, which is connected to the outlet hole 29. The mixer 34 is provided with a mixing chamber 35, and a steam pipe 36 is inserted into the mixing chamber 35. The steam channel 37 is connected to the mixing chamber 35, and the mixing chamber 35 is connected to the inlet hole 21. An outlet hole 33 is connected to the bottom of the mixing chamber 35, and an inner cavity 32 is connected to the bottom of the outlet hole 33. An outlet hole 31 is provided in the discharge nozzle 14, which is connected to the inner cavity 32. Steam enters the mixing chamber 35 from the steam channel 37, and the milk flowing out of the outlet hole 29 enters the mixing chamber 35 along the inlet hole 21. After the steam and milk are mixed, milk foam is formed and enters the inner cavity 32 from the outlet hole 33, and then flows out downward from the outlet hole 31.

[0023] When using the equipment, it needs to be connected to the beverage machine. Steam pipe 36 is connected to the steam pipe, and injection block 27 is connected to the milk pipe to maintain a continuous supply of raw materials.

[0024] When adjusting the extension and retraction of the lifting box 12, simply pull it by hand. The side plate 42 slides within the slide groove 41, which provides a certain range of motion to prevent the lifting box 12 from being completely pulled out. During the pulling process, the trapezoidal spring piece 44 abuts against the inner wall of the box 11, maintaining a certain elastic damping. This ensures that after the lifting box 12 is pulled out to a certain length, the relative position of the lifting box 12 and the box 11 is maintained when the operator releases their hand.

[0025] When removing the base plate 13 and the milk foam module, press the third plate 53 and then pinch it to disengage the base plate 13 from the lifting housing 12. Pressing the third plate 53 will bring the latch 52 closer to the first plate 51, disengaging it from the slot 54. When reinstalling the base plate 13 and the milk foam module, simply move the base plate 13 upwards from the bottom of the lifting housing 12 until the latch 52 engages with the slot 54.

[0026] When the device produces milk foam, steam is introduced through the steam channel 37 and milk is introduced through the injection hole 26. After mixing, milk foam is formed and flows out downward from the outlet hole 31 of the discharge nozzle 14.

[0027] The connection hole 24 is smaller than the injection hole 26, which reduces the flow rate. Furthermore, the milk flows through the annular groove 25 before entering the outlet hole 29, which acts as a buffer to prevent the milk from flowing too fast and affecting the milk foam processing effect.

[0028] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
