Technical Field

[0001] This utility model relates to the field of push pumps, and in particular to a multifunctional pump. Background Technology

[0002] Existing push pumps generally do not have the function of adjusting the liquid dispensing mode and the liquid dispensing volume.

[0003] For example, patent document CN211224625U discloses a press pump including a press head, a toothed sleeve, a piston rod, and a cylinder. At least one locking head is formed on the outer surface of the piston rod, and the locking head includes an upper support surface and a lower support surface. An inner ring is formed in the toothed sleeve, through which the piston rod extends. A support ring is formed on the inner surface of the inner ring, and at least one notch is provided on the support ring, allowing the locking head to slide up and down within the notch.

[0004] For example, patent document CN218807741 U discloses an impact-resistant push pump including a pressure head and a dental sleeve.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 5 A multifunctional pump includes: a toothed cap 1, a pump body 2 at the bottom of the toothed cap 1, a limiting part 3 movably mounted on the top of the toothed cap 1, and a pressing head 4 above the limiting part 3. The pressing head 4 is operatively connected to the pump body 2. The limiting part 3 is located between the toothed cap 1 and the pressing head 4, and is rotatably connected to the pump body 2. The pump body 2 has multiple bosses 23 of different heights. After the limiting part 3 rotates, it abuts against different bosses 23 to limit the stroke of the pressing head 4, thereby adjusting the liquid output.

[0025] In a preferred embodiment, the pump body 2 includes a main body 21. A guide groove 22 is formed on the inner wall of the main body 21. The guide groove 22 is spiral-shaped and has multiple bosses 23. A plug-in part 31 is provided at the bottom of the limiting part 3, and the plug-in part 31 is movably inserted into the main body 21. The plug-in part 31 has guide blocks 32 that correspond one-to-one with the guide grooves 22, extending into the guide grooves 22. In use, rotating the limiting part 3 causes the guide blocks 32 to slide within the guide grooves 22, allowing the limiting part 3 to rise or fall. When the guide blocks 32 engage with the bosses 23, the limiting part 3 cannot move downwards. The pressing head 4 abuts against the limiting part 3 during the pressing process, thereby controlling the amount of pressure applied by the pressing head 4 and consequently controlling the liquid output.

[0026] In a preferred embodiment, the pressing head 4 is connected to a liquid outlet tube 5, and the end of the liquid outlet tube 5 is provided with an insertion tube 51. The insertion tube 51 has a first through hole 52 and a tube cap 6. The tube cap 6 has a liquid outlet 61 and a foam outlet 62. In use, rotating the tube cap 6 can connect the liquid outlet 61 to the first through hole 52 or the foam outlet 62 to the first through hole 52.

[0027] In a preferred embodiment, the tube cap 6 has two cavities 63, which are respectively connected to the liquid outlet 61 and the foam outlet 62. Each cavity 63 has a second through hole 64, which is adapted to the first through hole 52. When the tube cap 6 is rotated, the two second through holes 64 rotate accordingly, thereby connecting the second through holes 64 with the first through hole 52. The liquid or foam pumped by the pump body 2 can then enter the cavity 63 and be discharged through the liquid outlet 61 and the foam outlet 62.

[0028] In a preferred embodiment, the insertion tube 51 is provided with an annular groove 53, and the inner wall of the tube cap 6 is provided with an annular protrusion 65, which is embedded in the annular groove 53. This facilitates the connection between the tube cap 6 and the insertion tube 51.

[0029] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
