[0027] Embodiment 1:

[0028] Reference Figure 1 , an embodiment of the present application provides a homogenizer 100, specifically, the homogenizer 100 includes a piston member 10, a filter layer 20 and a homogenized particle layer 30. The piston member 10 includes a tube body 11 and a push rod 12, the tube body 11 has a liquid suction port 101, exemplary, the tube body 11 can be a cylindrical tube body, the push rod 12 can be slidably attached to the tube body 11, and the push rod 12 is used to move toward or away from the liquid suction port 101 to change the pressure in the tube body 11, so as to complete the operation of discharging or sucking liquid. Exemplarily, the tube body 11 and the push rod 12 can both be plastic parts. The filter layer 20 is arranged at one end of the tube body 11 adjacent to the liquid suction port 101. The homogenized particle layer 30 is arranged in the tube body 11 on the side of the filter layer 20 away from the liquid suction port 101.

[0029] During specific use, a sample can be added to the tube body 11, and then the push rod 12 can be inserted. The push rod 12 can be moved to generate a negative pressure in the cavity between the push rod 12 and the tube body 11 (the push rod 12 moves away from the liquid aspiration port 101). The negative pressure causes the extraction liquid outside the piston 10 to enter the tube body 11 from the liquid aspiration port 101. Then, the homogeneous particles in the homogeneous particle layer 30 can be violently shaken by manual shaking or by shaking with an oscillator to break the sample, thereby achieving a homogenization effect. Then, the push rod 12 can be moved to generate a positive pressure (the push rod 12 moves toward the liquid aspiration port 101) to remove the extraction liquid that has completed the sample extraction from the tube body.

[0030] In the present application, the homogenizer 100 integrates the piston 10, the filter layer 20 and the homogenized particle layer 30, so that the homogenizer 100 can complete the whole process of aspiration, homogenization and filtration during use, thereby simplifying the steps of sample pretreatment, thereby saving manpower and material resources to reduce processing costs. The homogenizer 100 is suitable for samples without extracting liquid and samples containing extracting liquid. When the tube body 11 contains extracting liquid, the use of the homogenized particle layer 30 can achieve homogenization while extracting the sample, which can effectively improve the extraction rate of the sample.

[0031] In some embodiments, the filter layer 20 includes a screen 21. For example, the number of screens 21 can be one or more layers. When the number of screens 21 is multiple, they can be stacked in sequence. For example, the screen 21 can include a synthetic fiber screen, a metal wire screen, or a silk screen. Filtering through the screen is relatively simple in structure on the one hand, and is conducive to reducing the rate pressure on the other hand, thereby facilitating the improvement of filtering simplicity.

[0032] In other embodiments, the filter layer 20 may include filter paper or a filter element.

[0033] In some embodiments, the homogeneous particle layer 30 is a silicon dioxide particle layer, a quartz particle layer, a lead particle layer, an iron particle layer or a ceramic particle layer. The homogeneous particles of the above materials have a high hardness, which is conducive to further improving the homogenization effect.

[0034] In some embodiments, the tube body 11 is a transparent part. Exemplarily, the tube body 11 can be a transparent plastic part. Exemplarily, the material of the transparent plastic part can be transparent polypropylene, transparent polycarbonate or transparent acrylic, so as to facilitate observation of the situation inside the tube body, such as the homogenization effect of the sample, the injection volume of the sample, whether the filter layer is misaligned, etc.

[0035] In some embodiments, the tube body 11 is provided with a volume scale 102, so as to facilitate quantitative observation of the volume of liquid aspiration and liquid discharge. The unit of the volume scale 102 can be set according to the size of the tube body.

[0036] In some embodiments, the tube body 11 includes a first tube portion 111 and a second tube portion 112 stacked together. For example, the first tube portion 111 and the second tube portion 112 can be integrally formed, the liquid suction port 101 is provided on the first tube portion 111, and the circumferential outer surface of the second tube portion 112 is convexly provided on the circumferential outer surface of the first tube portion 111. In specific use, the push rod 12 is inserted into the first tube portion 111 from the second tube portion 112. The structure of the tube body 11 is conducive to improving the convenience of pushing and pulling the piston member 10.

[0037] In some embodiments, the push rod 12 includes a rod portion 121 and a plug portion 122 connected to each other. Exemplarily, the plug portion 122 can be sleeved on the periphery of the rod portion 121, or the plug portion 122 can be bonded to the rod portion 121. At least the plug portion 122 can be slidably attached to the tube body 11. The plug portion 122 is a soft rubber part. Exemplarily, the material of the soft rubber part can be rubber or silicone. Exemplarily, the plug portion 122 can be a cylinder, and the soft rubber part can improve the fit and sealing.

[0038] In some embodiments, the rod portion 121 includes a first portion 1211 and a second portion 1212 stacked together. For example, the first portion 1211 and the second portion 1212 may be integrally formed, the first portion 1211 is adjacent to the plug portion 122, and the circumferential outer surface of the second portion 1212 is convexly disposed on the circumferential outer surface of the first portion 1211. The structure of the rod portion 121 is conducive to improving the push-pull convenience of the piston member 10.

The screens 21 cooperate with the adsorption medium powder to enhance the selectivity of the filtration.

[0041] In some embodiments, the adsorption medium powder layer 22 is one of an adsorption resin powder layer, a diatomaceous earth powder layer, an activated clay powder layer, an activated carbon powder layer or a C18 powder layer. The adsorption medium powder of the above materials is conducive to further improving the adsorption effect. Exemplarily, the adsorption resin powder may include macroporous adsorption resin powder, such as ADS macroporous adsorption resin powder, and exemplary, the adsorption resin powder may include polystyrene resin powder. Exemplarily, the C18 powder may include octadecylsilane bonded silica gel filler powder, and exemplary, it may be a single-bonded octadecylsilane bonded silica gel filler, a double-bonded octadecylsilane bonded silica gel filler, a capped octadecylsilane bonded silica gel filler, and an amide group-embedded octadecylsilane bonded silica gel filler.

[0042] Optionally, the adsorption medium powder layer 22 may be arranged according to the actual usage of the sample and the extract.
