[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] See Figure 1 , Figure 1 This is a schematic diagram of an emulsion pump with particle crushing function provided in an embodiment of the present invention. The emulsion pump includes an emulsion pump head 110 and a particle crushing accessory 120. The particle crushing accessory 120 is disposed within the pumping channel of the emulsion pump head 110 and is used to process gel-like particulate matter in the emulsion during the pumping process. Figure 2 and 3As shown, the particle crushing accessory 120 includes a main body 210 and filters (including a first filter 220 and a second filter 230) welded to the upper and lower ends of the main body 210. The main body 210 has a hollow structure, forming a channel for the emulsion to flow. The first filter 220 and the second filter 230 cover the openings at the upper and lower ends of the main body 210 and smoothly transition with the inner wall of the main body 210, ensuring that the emulsion can flow smoothly through the filters. The first filter 220 and the second filter 230 are used to filter and crush gel-like particles in the emulsion. When the emulsion passes through the pump channel under pump pressure, it first flows through the second filter 230, then through the hollow channel of the main body 210, and finally through the first filter 220. During this process, the gel-like particles are crushed by the interception and shearing action of the filters, resulting in a delicate texture in the pumped liquid. When applied to the face, it is absorbed faster and without a grainy feel, effectively improving the user experience.

[0024] In one feasible embodiment, the outer wall of the main body 210 of the particle crushing accessory 120 is provided with an annular locking protrusion 130, which has a certain elastic deformation capability. Correspondingly, the inner wall of the pumping channel of the emulsion pump head 110 is provided with an annular locking groove 140 that matches the annular locking protrusion 130. The depth and width of the annular locking groove 140 match the size of the annular locking protrusion 130. The particle crushing accessory 120 is detachably connected to the pumping channel by the annular locking protrusion 130 engaging with the annular locking groove 140. This connection structure not only ensures that the particle crushing accessory 120 is stable and does not shake during pumping, but also facilitates disassembly for cleaning or replacement after long-term use, avoiding filter clogging that could affect the pumping effect.

[0025] In one feasible embodiment, the main body 210 is a multi-step hollow columnar structure, with each step surface connected by a smooth transition surface. The outer wall of the main body 210 is provided with a positioning step for engaging with the inner wall of the pump fluid channel. This positioning step is integrally formed on the annular locking protrusion 130. When the particle crushing accessory 120 is engaged into the annular groove 140 through the annular locking protrusion 130, the end face of the positioning step exactly abuts against the end face of the annular groove 140. Through the fitting and limiting of the two, the axial position of the particle crushing accessory 120 in the pump fluid channel is precisely limited, preventing axial displacement under the impact of liquid flow, and further improving the connection stability.

[0026] In one feasible embodiment, the end faces of the upper and lower ends of the main body 210 are smooth planes to ensure a tight fit when welding with the filter screen, reduce welding gaps, and prevent emulsion residue or leakage in the gaps.

[0027] In one feasible embodiment, the filter screen aperture at the inlet end of the particle crushing accessory 120 is larger than that at the outlet end. The inlet end is the end closer to the emulsion storage chamber (i.e., the second filter screen 230), and the outlet end is the end closer to the outlet (i.e., the first filter screen 220). This design allows larger gel-like particles to be initially intercepted and sheared into smaller particles by the filter screen at the inlet end. Subsequently, the smaller particles are further crushed as they flow through the filter screen at the outlet end, creating a staged crushing effect. This not only avoids large particles directly clogging the filter screen at the outlet end but also ensures that there are no obvious particles in the final pumped emulsion.

[0028] In one feasible embodiment, the particle crushing accessory 120 is made of either nylon or PET plastic, meaning that the main body 210, the first filter screen 220, and the second filter screen 230 are all made of either nylon or PET plastic. These materials have good corrosion resistance and processing performance, can adapt to the chemical composition of the emulsion, and are not prone to reacting with the emulsion, ensuring safe use.

[0029] In one feasible embodiment, the filter screens (first filter screen 220, second filter screen 230) can be connected to the upper and lower end faces of the main body 210 via ultrasonic welding. During welding, high-frequency vibration melts and fuses the contact surfaces of the filter screens and the main body 210, forming a strong connection structure. This welding method requires no additional adhesives or connectors, does not contaminate the emulsion, and provides good sealing at the weld joint, effectively preventing liquid leakage.

[0030] Understandably, the particle crushing accessory 120, which is manufactured by ultrasonic welding, has a filter screen pore size of 0.05 to 0.1 mm. When in use, after being filtered twice by the filter screen, the pumped emulsion can achieve a delicate user experience.

[0031] In a feasible embodiment, the inner wall of the main body 210 is provided with annular guide ribs inclined along the liquid flow direction. The number of guide ribs can be set to 2 to 3 rings, which are distributed at intervals along the axial direction of the main body 210. The guide ribs can guide the emulsion to flow along the central axis of the main body 210, avoiding the formation of eddies in the liquid on the inner wall of the main body 210 and causing particle residue. At the same time, when the liquid flows through the guide ribs, local turbulence will be generated, which will enhance the collision and shearing effect between the particles and the filter screen, and further improve the crushing effect.

[0032] In one feasible embodiment, the middle section of the main body 210 is provided with an elastic buffer section, which can be made of silicone. Silicone has good elasticity and chemical resistance, and can adapt to the dimensional errors of pump channels in different batches, ensuring that the particle crushing accessory 120 fits tightly against the inner wall of the pump channel; at the same time, the elastic buffer section can also absorb the impact force during pumping, reduce the vibration of the main body 210 and the filter screen, and extend the service life.

[0033] In one feasible embodiment, the mesh of the filter can be square or rectangular, and is made using a monofilament weaving process; the diameter of the yarn between the holes can be 0.04 mm, which is as sharp as a knife edge and can easily cut up jelly-like particles.

[0034] In one feasible embodiment, the mesh of the filter can be hexagonal or circular. The hexagonal mesh has acute angles, which provides better shearing effect on particles and higher connection strength between the meshes, making it less susceptible to damage from particle impact. Circular meshes are easier to process and suitable for mass production. The appropriate mesh shape can be selected according to actual needs.

[0035] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of the present utility model.
