When the locking mechanism 9 is separated from the sliding support 7, the sliding support 7 is unlocked from the limiting rib 611, and the sliding support 7 can be driven by the elastic device 8 to move towards the end far away from the nozzle 602, so that the air suction pipeline 4 automatically retracts into the accommodating cavity.

In some embodiments, locking mechanism 9 includes a pull rod 91 and a spring 92. One end of the pull rod 91 is fixed on the limiting rib 611, and the other end of the pull rod 91 is used for being clamped with or separated from the sliding support 7, so that the locking and unlocking functions of the sliding support 7 are realized. The elastic sheet 92 is disposed on the limiting rib 611 and on a side of the pull rod 91 facing away from the sliding support 7, and the elastic sheet 92 is used for elastically abutting against a side of the pull rod 91 and enabling the pull rod 91 to stably contact with the sliding support 7.

In some embodiments, the side of the sliding bracket 7 close to the locking mechanism 9 is provided with a guide groove 75, and the guide groove 75 is used for cooperating with the pull rod 91, so that the pull rod 91 runs along a preset track in the guide groove 75. Specifically, after the sliding bracket 7 is slid to be in contact with the pull rod 91, the pull rod 91 can be inserted into the guide groove 75 and run along a predetermined trajectory in the guide groove 75. The elastic piece 92 elastically abuts against the pull rod 91 and enables the locking hook 911 to extend into the guide groove 75 to move along a predetermined trajectory.

Referring to fig. 12 to 20, in some embodiments, the guide groove 75 includes a first guide groove 751, a second guide groove 752, and a third guide groove 753, which are sequentially connected.

The first guide groove 751 and the third guide groove 753 both extend in the sliding direction of the sliding bracket 7, one end of the first guide groove 751 close to the spout 602 serves as an inlet end 7501 of the guide groove 75, one end of the third guide groove 753 close to the spout 602 serves as an outlet end 7502, and one end of the first guide groove 751 close to the spout 602 is communicated with one end of the third guide groove 753 close to the spout 602, that is, the outlet end 7502 is communicated with the inlet end 7501.

The end of the first guide groove 751 far from the nozzle 602 is spaced from the end of the third guide groove 753 far from the nozzle 602, and is communicated with the second guide groove 752. That is, the upper end of the second guide groove 752 communicates with the end of the first guide groove 751 remote from the spout 602, and the lower end of the second guide groove 752 communicates with the end of the third guide groove 753 remote from the spout 602. Therefore, the pull rod 91 can enter the guide groove 75 through the inlet end 7501, and can leave the guide groove 75 through the outlet end 7502 after traveling along the trajectory of the first guide groove 751, the second guide groove 752, and the third guide groove 753.

In some embodiments, the second guide groove 752 is located on a side of the first guide groove 751 and the third guide groove 753 away from the spout 602, and the locking notch 7521 is recessed on a wall of the second guide groove 752 on a side close to the spout 602. Meanwhile, a locking hook 911 is formed by bending a side of the pull rod 91 facing the guide groove 75.

When the sliding bracket 7 is driven by the suction pipeline 4 to slide toward the direction close to the nozzle 602, the locking hook 911 can extend into the first guiding groove 751 through the inlet end 7501 and enter the second guiding groove 752 along the first guiding groove 751.

When the locking hook 911 enters the second guiding groove 752 and is located at the locking opening 7521, the locking hook 911 can be clamped at the locking opening 7521 under the action of the elastic device 8, and at this time, the force of the sliding bracket 7 is balanced under the action of the acting force of the elastic device 8 and the pulling force of the locking hook 911, so as to realize the locking function of the sliding bracket 7, as shown in fig. 20. And when the locking hook 911 is located at the locking opening 7521 and the sliding bracket 7 slides again in a direction close to the spout 602, the locking hook 911 can move relative to the sliding bracket 7 and enter the third guide groove 753 along the second guide groove 752.

When the locking hook 911 enters the third guiding groove 753, the sliding bracket 7 can slide under the action of the elastic device 8 toward the end far away from the spout 602, and the locking hook 911 can move under the action of the elastic device 8 along the third guiding groove 753 toward the outlet end 7502 and leave the guiding groove 75 through the outlet end 7502.

Referring to fig. 13 in conjunction with fig. 16, 18 and 20, in some embodiments, a first guide surface 7522 and a first stop 7523 are sequentially disposed on a side wall of the second guide groove 752 away from the spout 602. The first guiding surface 7522 is disposed at an end of the second guiding groove 752 close to the first guiding groove 751, and the first stop 7523 is disposed at an end of the first guiding surface 7522 away from the first guiding groove 751, that is, the first guiding surface 7522 is engaged between an end of the first guiding groove 751 opposite to the nozzle 602 and the first stop 7523.

When the sliding bracket 7 slides in a direction approaching the spout 602 and the locking hook 911 enters the second guiding groove 752 along the first guiding groove 751, the locking hook 911 can enter the first stop 7523 along the first guiding surface 7522. At this time, since the locking hook 911 abuts against the first stop 7523, the sliding bracket 7 stops sliding in a direction approaching the nozzle 602, and the suction line 4 stops extending out of the nozzle 602. And the sliding support 7 at this moment can slide towards the direction far away from the spout 602 under the action of the elastic device 8, so that the locking hook 911 can smoothly enter and be clamped at the locking opening 7521.

Referring to fig. 13 in conjunction with fig. 16, 18 and 20, in some embodiments, a second guide surface 7524 is further disposed on a side of the second guide groove 752 facing the nozzle 602. The second guide surface 7524 is located between the first guide groove 751 and the locking opening 7521, and an end of the second guide surface 7524 adjacent to the first guide groove 751 is spaced from and opposite to the first locking opening 7523, and an end of the second guide surface 7524 adjacent to the locking opening 7521 is engaged with the locking opening 7521. Therefore, when the locking hook 911 is located at the first seam allowance 7523, under the action of the elastic device 8, the sliding bracket 7 can move to a side far away from the nozzle 602, so that the locking hook 911 abuts against the second guiding surface 7524 and can enter the locking opening 7521 along the second guiding surface 7524, and further can be smoothly clamped at the locking opening 7521.

Referring to fig. 13 in conjunction with fig. 16, 18 and 20, in some embodiments, a third guide surface 7525 and a second stop 7526 are sequentially disposed on a side wall of the second guide groove 752 away from the spout 602. The third guide surface 7525 is disposed on a side of the first stop 7523 close to the third guide groove 753, and the second stop 7526 is disposed at a junction between the second guide groove 752 and the third guide groove 753. That is, the third guide surface 7525 is disposed between the first and second stoppers 7523 and 7526, an end of the third guide surface 7525 adjacent to the first stopper 7523 is spaced apart from and opposed to the lock opening 7521, and an end of the third guide surface 7525 adjacent to the second stopper 7526 is engaged with the second stopper 7526. Therefore, when the locking hook 911 is located at the locking opening 7521, if the sliding bracket 7 slides again in a direction approaching the nozzle 602 under the pulling of the suction line 4, the locking hook 911 can abut against the third guiding surface 7525 and enter the second stopping opening 7526 along the third guiding surface 7525. At this time, since the locking hook 911 abuts against the second stop 7526, the sliding bracket 7 stops sliding again in the direction approaching the nozzle 602, and at this time, the air suction pipeline 4 is released, so that the sliding bracket 7 can slide in the direction away from the nozzle 602 under the action of the elastic device 8, and the locking hook 911 can move back to the inlet end 7501 toward the outlet end 7502 along the third guide groove 753.

Referring to fig. 7 and 13 in conjunction with fig. 16, 18 and 20, in some embodiments, a step surface 754 is provided in the guide groove 75 at the connection between the outlet end 7502 and the inlet end 7501, and the step surface 754 is used to prevent the latch hook 911 from entering the outlet end 7502 from the inlet end 7501. Due to the function of the spring piece 92, the end of the locking hook 911 can abut on the groove surfaces of the guide groove 75, that is, the first guide groove 751, the second guide groove 752, and the third guide groove 753. Therefore, when the latch hook 911 enters the inlet end 7501, the latch hook 911 can enter the first guide groove 751 along the step surface 754, and cannot enter the outlet end 7502 and the third guide groove 753 over the step surface 754. Meanwhile, when the locking hook 911 leaves the third guide groove 753, the locking hook 911 can smoothly return from the outlet end 7502 to the inlet end 7501 by the elastic piece 92 and leave the guide groove 75.

Referring to fig. 13 in conjunction with fig. 16, 18 and 20, in some embodiments, a fourth guide surface 755 is disposed on a sidewall of the inlet end 7501. The fourth guiding surface 755 is located on a side of the step surface 754 close to the nozzle 602, and the step surface 754 is engaged between the fourth guiding surface 755 and a groove wall of the first guiding groove 751. When the sliding bracket 7 slides in a direction approaching the spout 602 and contacts the locking hook 911, the fourth guide surface 755 can serve as a contact surface of the sliding bracket 7 with the locking hook 911, so that the locking hook 911 can smoothly enter the first guide groove 751 through the fourth guide surface 755 and the step surface 754 in sequence, as shown in fig. 18.
