Abstract
Description
Technical Field
[0001] This utility model belongs to the field of press pump technology, specifically relating to a pump head structure for preventing accidental pressurization of a foam pump. Background Technology
[0002] A press pump is a type of extraction component installed on various containers. By pressing the pump head, the press pump draws liquid from the container and sprays it out. With the continuous development of technology, gas is now simultaneously input during the use of press pumps, allowing air and liquid to be sprayed out of the pump head at the same time, resulting in a foamy liquid. It is now a common component used in spray bottles and other similar products.
[0003] Current push-button pumps primarily work by compressing the air inside the pump body through seals, allowing liquid from the container to enter the pump body under pressure. However, there are certain problems in actual use. Specifically, these pumps lack any anti-accidental-touch components, making it easy for operators to accidentally activate them during daily use, causing the liquid inside the container to spray out directly. This operation is extremely dangerous when the container contains special liquids, endangering the safety of nearby operators. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.
[0006] A foam pump head structure for preventing accidental pressure includes an outer shell, a press pump body, a spray pump head, and a connecting shell. The press pump body is slidably installed inside the outer shell, the spray pump head is installed at the top of the press pump body, and the connecting shell is installed at the bottom of the outer shell. A locking mechanism for limiting the press pump body is installed on the side of the outer shell. The locking mechanism includes a rotating component, a rotating plate, a plug-in plate, and a plug-in groove. An installation groove is opened on the side of the outer shell, and the rotating component is installed inside the installation groove. The rotating plate is installed at the end of the rotating component, and the plug-in plate is installed on one side of the rotating plate. The press pump body and the inner shell of the outer shell both have a plug-in groove for insertion with the plug-in plate.
[0007] As a preferred technical solution of this utility model, the rotating assembly includes a rotating frame, a torsion spring, a movable frame, and a calibration plate. The rotating frame is installed in the mounting groove, and calibration plates are symmetrically arranged at both ends of the rotating frame. The movable frame is installed on the side of the calibration plate, and a torsion spring is arranged between the calibration plate and the rotating frame.
[0008] As a preferred technical solution of this utility model, the calibration plate slides inside the mounting groove, and a movable groove is provided inside the outer shell on the side of the mounting groove, and the movable groove is slidably connected to the movable frame.
[0009] As a preferred technical solution of this utility model, it also includes a sealing mechanism, which includes a base, a threaded end, a meshing groove and a sealing cover plate. The base is installed on the main body of the press pump, and a meshing groove is opened at the bottom opening of the spray pump head. A threaded end that meshes with the meshing groove is installed on the main body of the press pump, and a sealing cover plate is installed inside the spray pump head.
[0010] As a preferred technical solution of this utility model, the sealing mechanism further includes a gasket, and a gasket is installed at the top opening of the pressing pump body. The gasket has a groove with a radius smaller than the radius of the sealing cover plate itself.
[0011] As a preferred technical solution of this utility model, the top of the press pump body is symmetrically equipped with sliding blocks, and the inner wall of the spray pump head is provided with sliding grooves that slide with the sliding blocks.
[0012] As a preferred embodiment of this utility model, a plug-in port is installed at the bottom of the connecting shell, and a connecting pipe is installed on the plug-in port.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] In this invention, by setting a locking mechanism and a sealing mechanism, and using a moving and deflecting rotating plate, the insertion plate on the side of the rotating plate enters the insertion slot, thereby locking the position of the main body of the press pump. The main body of the press pump cannot slide inside the outer shell, and at this time the spray pump head cannot spray liquid. Adjusting the distance between the spray pump head and the main body of the press pump is used to seal and block the outlet of the gasket, further locking the overall structure of the pump body, realizing the function of preventing accidental contact of the pump body, and ensuring the safety of the pump body during use.

Detailed Implementation
[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.
[0025] Depend on Figure 1 and Figure 2 As shown, this is a schematic diagram of the anti-accidental pressure foam pump head structure in this embodiment. The pump head structure includes an outer shell 1, a press pump body 2, a spray pump head 3, and a connecting shell 4. The press pump body 2 is slidably installed inside the outer shell 1. The spray pump head 3 is installed at the top of the press pump body 2. Sliding blocks are symmetrically installed at the top of the press pump body 2. A sliding groove is opened on the inner wall of the spray pump head 3 to slide with the sliding blocks. The connecting shell 4 is installed at the bottom of the outer shell 1. A plug-in port is installed at the bottom of the connecting shell 4. A connecting pipe is installed on the plug-in port. A locking mechanism 5 is installed on the side of the outer shell 1 to limit the press pump body 2.
[0026] Install the main body 2 of the press pump at the top opening of the container to be pumped, and then ensure that the connecting pipe connected to the end of the connecting shell 4 is below the liquid level. Then, by pressing the spray pump head 3, the spray pump head 3 drives the main body 2 of the press pump to slide inside the outer shell 1, compressing the air inside the outer shell 1. At this time, the connecting pipe pumps the liquid inside the container.
[0027] From the appendix Figure 3 As shown, it is a structural schematic diagram of the locking mechanism 5 in this embodiment. The locking mechanism 5 includes a rotating component 51, a rotating plate 52, a plug-in plate 53 and a plug-in groove 54. The outer shell 1 has an installation groove on its side. The rotating component 51 is installed inside the installation groove. The rotating plate 52 is installed at the end of the rotating component 51. The plug-in plate 53 is installed on one side of the rotating plate 52. The press pump body 2 and the outer shell 1 have a common plug-in groove 54 for plugging into the plug-in plate 53.
[0028] During use, the rotating component 51 causes the rotating plate 52 to deflect towards the side closer to the main body 2 of the press pump. At this time, the plug plate 53 enters the plug slot 54 and locks the position of the main body 2 of the press pump. The main body 2 of the press pump cannot slide inside the outer shell 1, and the air inside the outer shell 1 is no longer compressed. At this time, the spray pump head 3 cannot drive the main body 2 of the press pump to move, thus achieving the protection of the entire pump body and the purpose of preventing accidental contact.
[0029] From the appendix Figure 4 As shown, this is a schematic diagram of the structure of the rotating assembly 51 in this embodiment. The rotating assembly 51 includes a rotating frame 511, a torsion spring 512, a movable frame 513, and a calibration plate 514. The rotating frame 511 is installed in the mounting groove. The calibration plates 514 are symmetrically arranged at both ends of the rotating frame 511. The movable frame 513 is installed on the side of the calibration plate 514. The torsion spring 512 is arranged between the calibration plate 514 and the rotating frame 511. The calibration plate 514 slides inside the mounting groove. A movable groove is opened inside the outer shell 1 on the side of the mounting groove. The movable groove is slidably connected to the movable frame 513.
[0030] In use, the torsion spring 512 releases its own elastic force, which drives the rotating frame 511 to rotate the rotating plate 52, causing the insertion plate 53 to enter the insertion slot 54, thus locking the position of the press pump body 2. When it is necessary to release the position lock of the press pump body 2, the rotating plate 52 is pulled to disengage the insertion plate 53 from the insertion slot 54, and the rotating plate 52 is pressed as a whole, causing the moving frame 513 to slide inside the moving slot, thus misaligning the insertion plate 53 and the insertion slot 54, so that the insertion plate 53 is no longer inserted into the insertion slot 54. At this time, the press pump body 2 can operate normally and be used.
[0031] From the appendix Figure 5 As shown, this is a structural schematic diagram of the blocking mechanism 6 in this embodiment. It also includes the blocking mechanism 6, which includes a base 61, a threaded end 62, a meshing groove 63, a blocking cover plate 64, and a gasket 65. The base 61 is installed on the press pump body 2. The meshing groove 63 is opened at the bottom opening of the spray pump head 3. The threaded end 62, which is threadedly connected to the meshing groove 63, is installed on the press pump body 2. The blocking cover plate 64 is installed inside the spray pump head 3. The gasket 65 is installed at the top opening of the press pump body 2. The gasket 65 has a hole with a radius smaller than the radius of the blocking cover plate 64.
[0032] By pressing the spray pump head 3, the spray pump head 3 slides on the top of the press pump body 2. Then, the spray pump head 3 is rotated so that the threaded end 62 engages with the meshing groove 63, causing the gap between the sealing cover plate 64 and the gasket 65 to gradually decrease until the sealing cover plate 64 and the gasket 65 are in contact. At this time, the holes and grooves on the gasket 65 are completely sealed, and the gas or liquid inside the press pump body 2 cannot flow out, thus achieving further sealing of the pump body.
[0033] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
