[0037] See also Figure 1 and Figure 2 The steam output device 1 includes a fixing component 11, a steam output pipe 12, a fixing frame 13 and a damping component 14. The fixing component 11 is used to be fixed to the frame 2 of the milk frothing machine 100. The steam output pipe 12 is rotatably connected to the fixing component 11, so that the angle of the steam output pipe 12 is adjustable. The steam output pipe 12 is used to transmit steam and spray steam into liquid milk. The fixing frame 13 accommodates at least part of the steam output pipe 12 and at least part of the fixing component 11. The fixing frame 13 is used to facilitate users to adjust the angle of the steam output pipe 12 to prevent users from touching the steam output pipe 12 and scalding the users. The damping component 14 is arranged in the fixing component 11, and the damping component 14 abuts against part of the steam output pipe 12 to provide damping force to the steam output pipe 12, so as to fix the steam output pipe 12 without external force.

[0038] For the above fixing component 11, please refer to Figure 2 The fixing assembly 11 includes a fixing sleeve 111 and a locking member 112. The fixing sleeve 111 includes a first sleeve 1111 and a second sleeve 1112. The first sleeve 1111 is connected to the second sleeve 1112. The first sleeve 1111 and the second sleeve 1112 are surrounded to form a rotation groove 1113. The rotation groove 1113 is rotatably connected to the steam output pipe 12. The locking member 112 is used to connect and fix the fixing sleeve 111 to the frame 2 of the milk frother 100.

[0039] For the steam output pipe 12, see Figure 2 and Figure 3The steam output pipeline 12 includes an outer tube 121, a steam nozzle 122 and an inner tube 123. The outer tube 121 is arranged in the fixing frame 13, and both ends of the outer tube 121 extend out of the fixing frame 13. A rotating part 1211 is arranged at one end of the outer tube 121, and the rotating part 1211 is rotatably arranged in the rotating groove 1113. The rotating part 1211 is spherical in shape so that the outer tube 121 rotates around the Z axis or around the X axis. The rotating part 1211 is provided with an avoidance gap 1212. The steam nozzle 122 is connected to the other end of the outer tube 121, and the steam nozzle 122 is provided with a first steam hole 1221 and a second steam hole 1222. The first steam hole 1221 and the second steam hole 1222 are both arranged obliquely. Along the Z-axis direction, the connecting line of the cross-section center of the first steam hole 1221 and the second steam hole 1222 passes through the cross-section center of the steam output pipe 12. The angle a between the connecting line of the cross-section center of the first steam hole 1221 and the second steam hole 1222 and the horizontal center line of the cross-section of the steam output pipe 12 is 45 degrees, that is, the angle a between the first steam hole 1221 and the horizontal center line of the cross-section of the steam output pipe 12 is 45 degrees, and the angle a between the second steam hole 1222 and the horizontal center line of the cross-section of the steam output pipe 12 is 45 degrees. The inner tube 123 is arranged in the outer tube 121 and the steam nozzle 122, and one end of the inner tube 123 extends out of the avoidance gap 1212 and passes through the fixing sleeve 111. The inner tube 123 connects the first steam hole 1221 and the second steam hole 1222. One end of the inner tube 123 is used to be connected and fixed to the steam generating device 4 of the milk frother 100. Among them, by the inclined arrangement of the first steam hole 1221 and the second steam hole 1222, and the angle between the cross-sectional center line of the first steam hole 1221 and the second steam hole 1222 and the cross-sectional horizontal center line of the steam output pipe 12 is 45 degrees, the steam ejected from the first steam hole 1221 and the second steam hole 1222 is obliquely ejected into the liquid milk, which can enhance the rotational force of the liquid milk, so that the air and the liquid milk are fully mixed, thereby making the milk foam of the liquid milk dense, delicate and smooth in taste. Furthermore, the avoidance gap 1212 is used to provide an avoidance space for the middle part of the inner tube 123, so that when the outer tube 121 rotates, the middle part of the inner tube 123 will not be squeezed by one end of the outer tube 121 to be concave, thereby reducing the risk of damage to the inner tube 123. Furthermore, the inner tube 123 is used to transmit steam to the steam nozzle 122, and part of the inner tube 123 is wrapped by the outer tube 121, so that the steam does not contact the outer tube 121, reducing the heat loss of the steam, thereby reducing the premature condensation of the steam into water droplets.

[0040] In some embodiments, see Figure 2 The inner wall of one end of the outer tube 121 is inclined so that there is an avoidance gap 1212 between the inner wall of one end of the outer tube 121 and the inner tube 123 .

[0041] In some embodiments, see Figure 4, the included angle b between the first steam hole 1221 and the second steam hole 1222 is 79.5 degrees to 82.5 degrees.

[0042] In some embodiments, the inner tube 123 is made of Teflon material.

[0043] For the above mentioned fixing bracket 13, see Figure 2 The fixing frame 13 is provided with a receiving groove 131, a light-transmitting hole 132 and a detection hole 133. The receiving groove 131 is provided at one end of the fixing frame 13, and the receiving groove 131 receives at least part of the fixing assembly 11. The light-transmitting hole 132 and the detection hole 133 are provided at the other end of the fixing frame 13 at intervals, the light-transmitting hole 132 is used for allowing the light of the laser 51 of the temperature detection module 5 to pass through, and the detection hole 133 is used for allowing the temperature sensor 52 of the temperature detection module 5 to detect the energy of the object to be detected. One end of the fixing frame 13 is used to extend from the opening 22 of the frame 2 of the milk frother 100 into the frame 2, so that the surface of the fixing frame 13 is used to abut against the wall surface of the opening 22, so as to limit the travel of the steam output pipe 12 rotating around the Z axis and the travel of the steam output pipe 12 rotating around the rotating part 1211 as the center.

[0044] In some embodiments, the steam output pipe 12 takes the preset first position as the initial position, the stroke that can be rotated clockwise around the Z axis and the stroke that can be rotated counterclockwise around the Z axis are both 0-15 degrees, and the stroke that can be rotated clockwise around the X axis is 0-30 degrees, and the preset first position is a position where the central axis of the fixing frame 13 is parallel to the central axis of the opening 22 of the frame 2. Figure 5 As shown by the arrow, when making milk foam, the steam output pipe 12 is rotated 30 degrees around the X axis with the preset first position as the initial position, and the steam is sprayed downward from the first steam hole 1221 and the second steam hole 1222 into the liquid milk, causing the liquid milk to rotate from the bottom to the top, so that the liquid milk and the air are fully mixed, thereby making the liquid milk more resistant to breaking. Figure 6 As shown by the arrows, when making milk foam, the steam output pipe 12 is rotated 30 degrees around the X axis with the preset first position as the initial position, and the steam output pipe 12 is rotated 15 degrees clockwise or counterclockwise around the Z axis with the preset first position as the initial position, and the steam is sprayed into the liquid milk from the first steam hole 1221 at an angle downward, and the steam is sprayed into the liquid milk from the second steam hole 1222 at an angle sideways, actuating the liquid milk to rotate clockwise, so that the liquid milk and the air are fully mixed, thereby making the liquid milk more resistant to bursting and denser.

[0045] For the damping assembly 14 above, see Figure 2The damping assembly 14 is arranged in the rotating groove 1113, and the damping assembly 14 includes a damping member 141, a first elastic member 142 and a damping ring 143. The damping member 141 abuts against one side of the rotating portion 1211. The first elastic member 142 is sleeved on the inner tube 123, one end of the first elastic member 142 abuts against the damping member 141, and the other end of the first elastic member 142 abuts against the groove of the rotating groove 1113. The damping ring 143 is sleeved on the other side of the rotating portion 1211, one side of the damping ring 143 abuts against the other side of the rotating portion 1211, and the other side of the damping ring 143 abuts against the wall surface of the rotating groove 1113. The elastic force of the first elastic member 142 makes the rotating portion 1211 abut against the damping ring 143 and the damping member 141 respectively to generate friction, so as to fix the steam output pipe 12.

[0046] In some embodiments, the first elastic member 142 is a spring.

[0047] In the embodiment of the utility model, the steam output device 1 includes a fixing component 11 and a steam output pipeline 12. The fixing component 11 is used to be fixed to the frame 2 of the milk frother 100. The steam output pipeline 12 includes an outer tube 121, a steam nozzle 122 and an inner tube 123. One end of the outer tube 121 is rotatably connected to the fixing component 11. An escape gap 1212 is provided at one end of the outer tube 121. The steam nozzle 122 is connected to the other end of the outer tube 121. The inner tube 123 is provided inside the outer tube 121 and the steam nozzle 122. One end of the inner tube 123 extends out of the escape gap 1212 and passes through the fixing component 11. The other end of the inner tube 121 is connected to the steam nozzle 122. By providing the escape gap 1212 at one end of the outer tube 121, an escape space is provided for the inner tube 123, so that the inner tube 123 will not be squeezed and folded by the inner wall of one end of the outer tube 121 when the outer tube 121 rotates, thereby reducing the risk of damage to the inner tube 123.

The wall surface of the opening 22 limits the travel of the fixing frame 13 of the steam output device 1 and the steam output pipe 12 to rotate clockwise or counterclockwise around the Z axis, and limits the travel of the clockwise rotation around the X axis. The filter 23 is arranged in the circulation slot 21, and the filter 23 is used to open the water tank 3 and filter the liquid.
