Description

Technical Field

[0001] This utility model relates to the field of foam pump technology, and in particular to a multi-network foam pump. Background Technology

[0002] For foam pump heads, liquid and gas mix in the pipe and form foam after passing through a filter. The advantages of push-button foam pumps include convenience, durability and safety. They are widely used in daily products such as shampoo, shower gel, and hand soap, providing a good user experience. In addition, the design of push-button foam pumps makes it easy to squeeze out liquid, solving the problem that traditional push-button containers are difficult to squeeze out completely.

[0003] For example, patent CN112320060A discloses a glass bead extrusion foam pump. The first foam mechanism is located inside the piston. The first foam mechanism includes a foaming net, an inner net, and friction balls. The inner net is installed inside the foaming net, and friction balls are installed inside both the inner net and the foaming net. When the foam liquid passes through the foaming net and the inner net, the loose and porous structure of the foaming net and the inner net facilitates the fusion of air and liquid, causing the foam liquid to produce foam. The second foam mechanism is a component with the same structure as the first foam mechanism. After multiple foam mechanisms, the produced foam is finer.

[0004] The problem with the above technology is that the foam pump has multiple foam mechanisms. When the foam liquid passes through the foam mechanism multiple times, the foam produced becomes finer. Therefore, the more foam mechanisms there are, the finer the foam produced. However, the foam mechanism is installed in different positions inside the foam pump. When additional foam mechanisms are needed, the installation position needs to be redesigned, which makes installation difficult.

[0005] To address these technical problems, a multi-network foam pump is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a multi-channel foam pump that can adjust the number of foaming components according to different types of foam liquids in the pump, thereby achieving the corresponding number of foaming times, and is easy to install.

[0007] The technical solution adopted by this utility model to solve the problem is: a multi-network foam pump, including a pump body, a pressing assembly on the pump body, the pressing assembly including a valve stem, at least one foaming assembly inside the valve stem, a through groove on the foaming assembly communicating with the valve stem, a foaming mesh in the through groove, and the outer side wall of the foaming assembly engaging with the inner side wall of the valve stem.

[0008] As a further improvement to the above technical solution, bubble-discharging nets are provided at both the top and bottom of the channel.

[0009] As a further improvement to the above technical solution, the outer wall of the foaming component is provided with a first annular groove or a first annular protrusion, and the inner wall of the valve stem is provided with a second annular protrusion adapted to the first annular groove or a second annular groove adapted to the first annular protrusion.

[0010] As a further improvement to the above technical solution, the valve stem includes an upper valve stem and a lower valve stem, a piston is provided between the upper valve stem and the lower valve stem, and a liquid passage is provided on the piston to connect the upper valve stem and the lower valve stem. The foaming component is disposed inside the upper valve stem.

[0011] As a further improvement to the above technical solution, the lower end of the bottommost foaming component is inserted into the liquid passage, and a third annular groove adapted to the first annular protrusion is provided on the inner wall of the liquid passage.

[0012] As a further improvement to the above technical solution, the pump body includes a main body and a thread covering the top of the main body, the piston dynamic seal is disposed in the main body, the lower valve rod is movably disposed in the main body, and the upper valve rod is movably disposed in the thread.

[0013] As a further improvement to the above technical solution, a spring seat is provided at the bottom of the main body, a platform extends outward from the outer side wall of the lower valve stem, a spring is sleeved on the lower valve stem, and the top and bottom of the spring abut against the platform and the spring seat, respectively.

[0014] As a further improvement to the above technical solution, the upper part of the upper valve stem extends to the outside of the thread, and a pusher is provided on the upper part of the upper valve stem. A liquid outlet is provided inside the pusher, and the upper valve stem is connected to the liquid outlet.

[0015] As a further improvement to the above technical solution, a limiting member is also included, wherein the limiting member is sleeved on the thread, and the bottom of the push head abuts against the top of the limiting member.

[0016] The beneficial effects of this utility model are: when the pressing component is pressed down, the foam liquid in the pump body can pass through the valve stem and flow through the foaming component. The foam liquid can be foamed through the foaming net in the channel. By setting multiple foaming components in the valve stem, the number of foaming times can be increased, thereby making the foam finer. The number of foaming components can be adjusted according to different types of foam liquid in the pump body, thereby achieving the corresponding number of foaming times.
