Description

Technical Field

[0001] The invention relates to the technical field of milk frothing, in particular to a self-resetting structure of a milk frothing steam pipe. Background Art

[0002] When drinking coffee, adding silky and delicate milk foam to the coffee can enhance the taste and texture of the coffee and serve as a good decoration. Milk foam is the product of a fine mixture of milk and air.

[0003] There are many structural forms of devices for making milk foam. A common method is to directly put cold milk into a cup and use a steam nozzle directly connected to a steam pipe to prepare foamed milk. For details, please refer to the Chinese patent "A New Steam Pipe" with patent application number CN202022037405.6.

[0004] When making milk froth, the steam pipe needs to be placed below the liquid surface to achieve the best effect. In the above solution, the steam pipe is universally connected through the ball head and nut. Although it can rotate freely within a certain angle range, it cannot automatically reset to the best working position and needs to be placed manually. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a self-resetting structure for a milk frothing steam pipe, which can automatically reset the milk frothing steam pipe to a working position without manual placement, in view of the current status of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a self-resetting structure of a milk steam pipe, characterized in that: it includes:

[0007] A panel having a give-way hole on its surface;

[0008] A steam pipe for frothing milk, the first end of which is rotatably mounted on the back of the panel, the second end of which passes through the clearance hole and is exposed on the front of the panel, the steam pipe for frothing milk being able to flip between a working position and a ready position under the action of an external force; and

[0009] The elastic member acts between the milk frothing steam pipe and the panel so that the milk frothing steam pipe always has a tendency to rotate to a working position.

[0010] In order to define the working position and the standby position of the milk frothing steam pipe, the first end of the milk frothing steam pipe is rotatably mounted on the back of the panel through a rotating bracket, the rotating axis of the rotating bracket extends in the left-right direction, the top side of the rotating bracket has a first stop block extending forward, and the bottom side of the rotating bracket has a second stop block extending forward;

[0011] When the milk frothing steam pipe is in the working position, the first stop block abuts against the back of the panel;

[0012] When the milk frothing steam pipe is in the ready position, the second stop block abuts against the back side of the panel.

[0013] In order to achieve the yielding function and minimize the diameter of the yielding hole as much as possible, the panel is arranged vertically, and the yielding hole is a waist-shaped hole extending in the vertical direction;

[0014] When the milk frothing steam pipe is in the working position, the milk frothing steam pipe is located at the bottom end of the clearance hole;

[0015] When the milk frothing steam pipe is in the ready position, the milk frothing steam pipe is located at the top end of the clearance hole.

[0016] In order to ensure aesthetics and structural safety, a pipe cover is also included which is sleeved on the outer periphery of the milk frothing steam pipe. The pipe cover can be slid up and down and limited to the back side of the panel so that it can always cover the clearance hole during the rotation of the milk frothing steam pipe.

[0017] In order to realize the rotatable installation of the rotating bracket on the back of the panel, a mounting plate is provided on the back of the panel, and two fixing seats are symmetrically arranged on the left and right. The rotating bracket is installed on the outer periphery of the first end of the milk steam pipe, and the left and right ends of the rotating bracket are rotatably connected to the two fixing seats through a rotating shaft.

[0018] In order to achieve the up and down sliding limit of the tube cover on the back of the panel, the mounting plate has a limit opening at the position corresponding to the clearance hole, and the diameter of the limit opening is larger than the clearance hole. The tube cover can be movably accommodated in the limit opening up and down, and the edge of the tube cover is clamped between the fixing seat and the panel.

[0019] In order to facilitate the installation of the elastic part, a fixed bracket is installed on the mounting plate at a position directly below the fixed seat, and the fixed bracket has a pin shaft extending in the left and right directions. The elastic part is a torsion spring, which is sleeved on the outer periphery of the pin shaft. The first end of the torsion spring abuts against the fixed bracket, and the second end of the torsion spring abuts against the rotating bracket.

[0020] In order to prevent the second end of the torsion spring from easily detaching from the rotating bracket, the second end of the torsion spring has a hook portion, and the hook portion is hooked above the second stop block.

[0021] In order to facilitate the installation of the mounting plate, the mounting plate is welded to the back side of the panel.

[0022] In order to ensure that the milk frothing steam pipe is in the best working position during operation, the second end of the milk frothing steam pipe has an insertion section, and when the milk frothing steam pipe is in the working position, the insertion section is arranged vertically.

[0023] Compared with the prior art, the advantages of the present invention are as follows: the milk frothing steam pipe is rotatably mounted on the panel so that it can be flipped between the working position and the standby position under the action of an external force, and an elastic member is provided between the milk frothing steam pipe and the panel so that the milk frothing steam pipe always has a tendency to rotate to the working position. In this way, the milk frothing steam pipe can be automatically reset to the working position without manual placement, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention is further described in detail below with reference to the accompanying drawings.

[0031] In the specification and claims of the present invention, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various exemplary structural parts and elements of the present invention, but these terms are used here only for the purpose of convenience of description and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only used as explanations and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0032] like Figures 1 to 6The figure shows a preferred embodiment of the self-resetting structure of the milk frothing steam pipe of the present invention. The self-resetting structure of the milk frothing steam pipe comprises a panel 1, a milk frothing steam pipe 2, an elastic member 3 and a pipe cover 4.

[0033] Among them, the panel 1 is arranged vertically, and a waist-shaped hole extending in the vertical direction is opened on the surface of the panel 1 as a clearance hole 11; a mounting plate 12 is welded on the back of the panel 1, and the mounting plate 12 has a limiting opening 121 at the position corresponding to the clearance hole 11, and the diameter of the limiting opening 121 is larger than the clearance hole 11; two fixing seats 13 symmetrically arranged on the left and the right are provided on the mounting plate 12; a fixing bracket 14 is installed on the mounting plate 12 at a position directly below the fixing seat 13, and the fixing bracket 14 has a pin shaft 141 extending in the left and right directions.

[0034] The first end of the steam pipe 2 for frothing milk is rotatably mounted on the two fixed seats 13 via a rotating bracket 21, and the second end has an insertion section 22 that passes through the clearance hole 11 and is exposed on the front of the panel 1. The steam pipe 2 for frothing milk can be flipped between the working position and the standby position under the action of an external force. Specifically, the rotating bracket 21 is mounted on the outer periphery of the first end of the steam pipe 2 for frothing milk, and the left and right ends of the rotating bracket 21 are rotatably connected to the two fixed seats 13 via a rotating shaft 211, and the axis of the rotating shaft 211 extends in the left-right direction; the top side of the rotating bracket 21 has a first stopper 212 extending forward; the bottom side of the rotating bracket 21 has a second stopper 213 extending forward.

[0035] The elastic member 3 is a torsion spring, which is sleeved on the outer circumference of the pin shaft 141. The first end of the torsion spring abuts against the fixed bracket 14, and the second end of the torsion spring has a U-shaped hook portion 31, which is hooked above the second stop block 213 and abuts against the rotating bracket 21, so that the milk steam pipe 2 always has a tendency to rotate to the working position.

[0036] The pipe cover 4 is sleeved on the outer circumference of the milk frothing steam pipe 2 and can be movably accommodated in the limiting opening 121, and the edge of the pipe cover 4 is clamped between the fixing seat 13 and the panel 1, so that it can slide up and down during the rotation of the milk frothing steam pipe 2 and always cover the clearance hole 11 on the panel 1.

[0037] When the milk steam pipe 2 is in the working position, Figure 3 As shown, the first stopper 212 abuts against the back of the panel 1 to prevent the milk frothing steam pipe 2 from further turning downward. At this time, the milk frothing steam pipe 2 is located at the bottom end of the clearance hole 11, and the insertion section 22 is arranged vertically;

[0038] When the milk steam pipe 2 is in the ready position, Figure 6As shown, the second stop block 213 abuts against the back of the panel 1 to prevent the milk frothing steam pipe 2 from further turning upward. At this time, the milk frothing steam pipe 2 is located at the top of the clearance hole 11.

[0039] The working principle of this embodiment is as follows: when in use,

[0040] (1) First, lift the milk steam pipe 2 to make it turn upward to overcome the elastic force of the elastic member 3 until the second stop block 213 abuts against the back of the panel 1. Figure 6 As shown, at this time, the milk steam pipe 2 is in the ready position;

[0041] (2) Then place the milk cup directly below the milk steam pipe 2;

[0042] (3) Finally, the milk frothing steam pipe 2 is lowered so that it turns downward under the elastic force of the elastic member 3 until the first stop block 212 abuts against the back of the panel 1. Figure 3 As shown, at this time, the milk frothing steam pipe 2 is in the working position, the insertion section 22 is arranged vertically and extends into the milk, and due to the setting of the elastic member 3, the milk frothing steam pipe 2 is always kept in the working position without external force, so that it is convenient for stable milk frothing;

[0043] In addition, in order to make way for the upside-down milk steam pipe 2, the diameter of the making way hole 11 is much larger than the diameter of the milk steam pipe 2, and the making way hole 11 will affect the aesthetics and structural safety. In the above scheme, by setting the pipe cover 4, during the turning process of the milk steam pipe 2, the pipe cover 4 slides up and down and always covers the making way hole 11 on the panel 1, which can ensure the aesthetics and structural safety.
