[0005] The low-pressure nozzle is fixedly connected to the outer sheath for easy removal as a whole. Compared to the threaded connection, it is fixed together here and can be disassembled as a whole, which is more convenient. The outer sheath is connected to the soap mixer by a locking mechanism. After the locking mechanism is pressed down, the outer sheath and the low-pressure nozzle can be pulled off the soap mixer for replacement of the foam ball.

[0006] Preferably, the low-pressure nozzle and the outer sheath are integrally formed, making it more robust and easier to disassemble.

[0007] Preferably, the locking mechanism includes a guide groove with an upward opening on the outer sheath and a retaining ring inserted into the guide groove for the soap mixer to pass through. The soap mixer has a retaining groove corresponding to the retaining ring in the circumferential direction. It also includes a support mechanism that elastically lifts the retaining ring upward. Normally, the inner diameter of the retaining ring is larger than the outer diameter of the retaining groove. Under the action of the support mechanism, the retaining ring abuts against the lower side of the retaining groove, thereby restricting the left and right movement of the retaining groove and achieving fixation. After pressing down the retaining ring, the outer sheath can be pulled out and the retaining ring can be removed from the soap mixer.

[0008] Preferably, the support mechanism includes a pressure plate installed on the upper end of the retaining ring, and the outer sheath has a receiving groove for the pressure plate to be inserted. In its natural state, the outer end face of the pressure plate is consistent with the outer end face of the outer sheath. The pressure plate and the bottom of the inner cavity of the receiving groove are connected by an elastic component to achieve upward elastic support. Under the action of the elastic component, the retaining ring is inserted upward into the retaining groove.

[0009] Preferably, the elastic component is a spring, with two springs provided on the left and right sides. At the same time, a spring groove is provided at the bottom of the receiving groove to hold the spring.

[0010] Preferably, the right end of the slot is provided with an annular limiting ring to prevent the soap mixer from being inserted too far, thus achieving limiting and positioning.

[0012] Preferably, it also includes an anti-slip mechanism disposed between the retaining ring and the outer sheath to prevent the retaining ring from slipping upward.

[0013] Preferably, the anti-detachment mechanism includes protrusions extending inward from both sides of the bottom of the inner cavity wall of the outer sheath, and the lower end of the retaining ring is provided with two elastic arc-shaped cards that are together in a "W" shape. The upper side of the protrusion is arc-shaped to facilitate the sliding of the card. There is a gap between the card and the retaining ring, which can be squeezed inward and is elastic, so as to facilitate insertion from the top and sliding over the protrusion.

[0014] A foam pitcher includes a foam head for replacing foam balls as described above, and a pitcher body connected to the head, with a straw connected to the head body inserted into the pitcher body.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the low-pressure nozzle and the outer sheath are integrally formed, and the outer sheath and the soap mixer are connected by a snap-fit ​​ring. In normal state, under the action of the spring, the snap-fit ​​ring is inserted into the slot from the bottom, thus fixing the soap mixer to the outer sheath and the low-pressure nozzle. When disassembling, simply press down on the pressure plate, and the snap-fit ​​ring slides down out of the slot. At the same time, the bottom of the snap-fit ​​ring also reaches the bottom of the inner cavity of the outer sheath. At this point, the outer sheath can be pulled off directly, and the snap-fit ​​ring slides to the left along the soap mixer, connecting to the low-pressure nozzle. This eliminates the need for a threaded connection between the low-pressure nozzle and the soap mixer; simply press down and pull it out. The snap-fit ​​connection allows for easy removal and replacement of the foam ball. Attached Figure Description

At the same time, a spring groove is provided at the bottom of the receiving groove 42 to hold the springs. An annular limiting ring 61 is provided at the right end of the retaining groove 6 to prevent the soap mixer 1 from being inserted too far, thus achieving limiting and positioning. A chamfer 51 is provided at the bottom right end of the retaining ring 5 to facilitate the insertion of the soap mixer 1. An annular chamfer can also be provided circumferentially at the left end of the soap mixer 1.

[0029] It also includes an anti-slip mechanism set between the retaining ring 5 and the outer sheath 4 to prevent upward slippage. The anti-slip mechanism includes protrusions 9 extending inward from both sides of the bottom of the inner wall of the outer sheath 4, and the lower end of the retaining ring 5 is provided with two elastic arc-shaped cards 52 that are together in a "W" shape. The upper side of the protrusion 9 is arc-shaped to facilitate the sliding of the cards 52. There is a gap between the cards 52 and the retaining ring 5, which can be squeezed inward and is elastic, so as to facilitate insertion from the top and sliding over the protrusion 9.

[0030] like Figure 7 As shown, a foam pot includes a foam pot head for easy replacement of foam balls, and a pot body 10 connected to the pot head, with a straw connected to the pot body inserted into the pot body 10.

[0031] Working principle: The low-pressure nozzle 3 and the outer sheath 4 are integrally formed, and the outer sheath 4 is connected to the soap mixer 1 by a snap-fit ​​ring 5. Under normal conditions, under the action of the spring 8, the snap-fit ​​ring 5 is inserted into the slot 6 from the bottom, thus fixing the soap mixer 1 to the outer sheath 4 and the low-pressure nozzle 3. When disassembling, press down on the pressure plate 7, and the snap-fit ​​ring 5 slides down out of the slot 6. At the same time, the bottom of the clip 52 also reaches the bottom of the inner cavity of the outer sheath 4. At this time, the outer sheath 4 can be pulled off directly, and the snap-fit ​​ring 5 slides to the left along the soap mixer 1, connecting to the low-pressure nozzle 3. In this way, there is no need for the low-pressure nozzle 3 to be threadedly connected to the soap mixer 1. It can be directly pulled out by pressing down and the snap-fit ​​connection can be used to remove the foam ball 2 for easy replacement.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
