[0025] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures, or characteristics that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0027] Embodiment 1

[0028] Reference Figures 1 to 5 As shown in Figures 1 to 5 , this is the first embodiment of the present utility model. This embodiment provides an emulsion pressure pump head with a retractable nozzle. The emulsion pressure pump head with a retractable nozzle includes a main body assembly 100 and an opening and closing assembly 200. The two cooperate to close the nozzle to prevent the emulsion from flowing out of the nozzle.

[0029] The main body assembly 100 includes a telescopic head 101, a support tube 102, and a bottle cap 103. The support tube 102 is sleeved outside the telescopic head 101. The support tube 102 and the telescopic head 101 are threadedly connected. The bottle cap 103 is fixed to the bottom of the support tube 102.

[0030] The telescopic head 101 is mainly used to control the extension and retraction of the nozzle. The telescopic head 101 is usually the part directly associated with the user's operation. By rotating the telescopic head 101, the telescopic head 101 moves on the support tube 102, thereby realizing the telescopic function of the nozzle. The support tube 102 has a supporting and guiding function. It provides a stable track and structural support for the movement of the telescopic head 101, ensuring that the telescopic head 101 can smoothly perform the telescopic action. At the same time, it also helps to maintain the structural stability of the entire pump head. The bottle cap 103 plays a role in sealing and protecting, preventing the emulsion from leaking and foreign impurities from entering. On the other hand, it is connected to the bottle body, providing a basis for the installation and fixation of the entire pressure pump head, ensuring the stability of the pump head during use.

[0031] The opening and closing assembly 200 is arranged on the telescopic head 101 and includes an expansion member 201, a limiting member 202, and a support member 203. The expansion member 201 is arranged at one end of the telescopic head 101. The limiting member 202 is arranged on the expansion member 201. The support member 203 is located on the limiting member 202.

[0032] Through the setting of the expansion member 201, the telescopic head 101 can be closed. When the emulsion is squeezed out, closing the telescopic head 101 can prevent the emulsion from overflowing. After closing the telescopic head 101, the limiting member 202 can limit the expansion member 201 to prevent the expansion member 201 from moving by itself and causing the telescopic head 101 to open. Through the setting of the support member 203, the limiting member 202 can be supported to prevent the limiting member 202 from shifting.

[0033] Embodiment 2

[0034] Reference Figures 1 to 5 As shown in Figures 1 to 5 , this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0035] Specifically, the expansion member 201 includes a support disk 201a and a moving block 201b. The support disk 201a is fixed to one end of the telescopic head 101, and the moving block 201b is arranged on one side of the support disk 201a.

[0036] The number of the moving blocks 201b is six, and they are all arranged on one side of the support disk 201a. By moving the six moving blocks 201b to fit together, the telescopic head 101 can be closed to prevent the emulsion from leaking. The support disk 201a is used to support the moving blocks 201b to prevent the moving blocks 201b from shifting.

[0037] Specifically, the expansion member 201 further includes a slider 201c. The slider 201c is fixed to one side of the moving block 201b. A sliding groove X is formed on one side of the support disk 201a, and the slider 201c slides in the sliding groove X.

[0038] The number of the sliders 201c is six, and they are all fixed to one side of the moving block 201b. When the moving block 201b moves, it will drive the slider 201c to slide in the sliding groove X, so as to guide the moving block 201b to close or open the six moving blocks 201b.

[0039] Specifically, the expansion member 201 further includes a drive bar 201d and a rotating frame 201e. The drive bar 201d is fixed to one side of the moving block 201b, and the rotating frame 201e is sleeved outside the drive bar 201d. The rotating frame 201e and the drive bar 201d are movably connected.

[0040] A drive groove corresponding to the drive bar 201d is provided on the rotating frame 201e. By rotating the rotating frame 201e, the drive groove can squeeze the drive bar 201d to make the drive bar 201d move. The number of the drive bars 201d is six, and they all slide in the drive groove. By moving the drive bars 201d, the moving blocks 201b can be driven to move.

[0041] Specifically, the expansion member 201 further includes a rotating handle 201f, and the rotating handle 201f is sleeved outside the rotating frame 201e.

[0042] By rotating the rotating handle 201f, the rotating frame 201e can be driven to rotate. When the rotating frame 201e rotates, the drive groove can squeeze the drive bar 201d to make the drive bar 201d move.

[0043] Specifically, the limiting member 202 includes a limiting plate 202a and a limiting block 202b. The limiting plate 202a is fixed to one side of the support disk 201a, and the limiting block 202b is arranged on one side of the limiting plate 202a.

[0044] A limiting groove corresponding to the limiting block 202b is provided on one side of the limiting plate 202a. After the rotating frame 201e is rotated to a specified position, in order to prevent the rotating frame 201e from rotating by itself, the rotating frame 201e can be limited by engaging the limiting block 202b with the limiting groove. The limiting plate 202a is used to support the limiting block 202b to prevent the limiting block 202b from shifting.

[0045] Specifically, the limiting member 202 further includes a pull rod 202c, and the pull rod 202c is fixed to one side of the limiting block 202b.

[0046] When it is necessary to release the limit on the rotating frame 201e, by pulling the pull rod 202c, the pull rod 202c drives the limiting block 202b to separate from the limiting groove, so that the limit on the rotating frame 201e can be released, and the rotating frame 201e can rotate.

[0047] Embodiment 3

[0048] Refer to Figures 3 to 5 , which is the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the limiting member 202 further includes a pressure plate 202d and a spring 202e. The pressure plate 202d is sleeved outside the pull rod 202c, and the spring 202e is fixed to one side of the pressure plate 202d.

[0050] When pulling the pull rod 202c, it can drive the pressure plate 202d to move. The movement of the pressure plate 202d can exert an extrusion force on the spring 202e. The pull rod 202c drives the limiting block 202b to separate from the limiting groove, so that the limit on the rotating frame 201e can be released. When it is necessary to limit the rotating frame 201e again, release the pull rod 202c, and the elastic force of the spring 202e can drive the limiting block 202b to engage with the limiting groove, so that the rotating frame 201e can be limited again.

[0051] Specifically, the support member 203 includes a support shell 203a. The support shell 203a is sleeved outside the pull rod 202c, and the support shell 203a is movably connected to the pull rod 202c.

[0052] The support shell 203a is used to support the pull rod 202c to prevent the pull rod 202c from shifting during movement.

[0053] Specifically, the support member 203 includes a support bar 203b and a moving plate 203c. The support bar 203b is sleeved outside the support shell 203a. The support bar 203b is fixed to one side of the rotating handle 201f, and the moving plate 203c is fixed to one end of the pull rod 202c.

[0054] The support bar 203b is used to support the support shell 203a to prevent the support shell 203a from shifting. The setting of the moving plate 203c facilitates the user to move the pull rod 202c.

[0055] When in use, when it is necessary to close the telescopic head 101, first, the limit on the handle 201f needs to be released. By moving the moving plate 203c, the movement of the moving plate 203c drives the movement of the pull rod 202c. When the pull rod 202c moves, it can exert a squeezing force on the spring 202e. The pull rod 202c drives the limit block 202b to separate from the limit groove, thereby releasing the limit on the rotating frame 201e. Then, the handle 201f is rotated. The handle 201f drives the rotation of the rotating frame 201e. By the rotation of the rotating frame 201e, the driving groove squeezes the driving strip 201d, causing the driving strip 201d to move. By the movement of the driving strip 201d, the moving block 201b can be driven to slide in the sliding groove X, thereby guiding the moving block 201b and making the six moving blocks 201b move towards each other, so as to close the telescopic head 101 and prevent the emulsion from leaking. After closing the telescopic head 101, the handle 201f needs to be limited again. Release the pull rod 202c. The elastic force of the spring 202e rebounding can drive the limit block 202b to engage with the limit groove, thereby limiting the rotating frame 201e again and further limiting the handle 201f again.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
