DETAILED DESCRIPTION

[0035] In order to make the above objectives, characteristics and advantages of the present application more apparent, more comprehensible, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0036] Please refer to Figure 1 In a first aspect, the embodiments of the present application provide a discharging structure 100, comprising a connecting piece 1, a pump core assembly 2, a guide assembly 3 and a pressing piece 4. The connecting piece 1 is used to connect with a plurality of containers (not shown in the figure), each of which is used to contain different material bodies. Please refer to Figure 2 The pump core assembly 2 comprises a plurality of pump cores 21, each of which is connected with the connecting piece 1, and the material body inlet end 212 of each pump core 21 is in communication with the corresponding container. Please refer to Figure 3 The guide assembly 3 is provided with a plurality of spaced guide channels 31, each of which is in communication with the corresponding material body outlet end 211. Please refer to Figure 1 The pressing piece 4 is movably connected with the connecting piece 1, and the pressing piece 4 abuts against the guide assembly 3. The pressing piece 4 is used to move relative to the connecting piece 1 to drive the guide assembly 3 to press all the pump cores 21, so that each pump core 21 pumps the material body in the corresponding container into the corresponding guide channel 31. The above-mentioned discharging structure 100 is provided with the connecting piece 1, which can be connected with a plurality of containers containing different material bodies, and can serve as a supply source of multi-element material bodies. The pump core assembly 2 is provided with a plurality of pump cores 21, each of which is in communication with the corresponding container. When the pressing piece 4 is actuated, all the pump cores 21 can be pressed simultaneously. The guide assembly 3 is connected with the material body outlet ends 211 of all the pump cores 21, and a plurality of guide channels 31 are spaced inside the guide assembly 3 and are in communication with the corresponding material body outlet ends 211. Different material bodies pumped out by the pump cores 21 will enter the corresponding guide channels 31 respectively, avoiding mixing and confusion of the material bodies, and enabling precise control of the delivery path of each material body. The pressing piece 4 is movably connected with the connecting piece 1 and abuts against the guide assembly 3. The user only needs to operate this one pressing piece 4 to drive the guide assembly 3 to press all the pump cores 21 synchronously, thereby completing the pumping of multiple material bodies. Compared with the traditional single-channel pump head which needs to be pressed one bottle at a time, the operation process is greatly simplified, and the practical operation convenience is significantly improved.

[0037] Please refer to Figure 2In optional embodiments, the connecting member 1 can be connected to two, three, four, five, six or more containers, and each container can contain the same or different material. The number of pump cores 21 corresponds to the number of containers, and the pump core 21 can be two, three, four, five, six or more. The pump core 21 can be a liquid pump, and the pump core 21 can pump the material in the container into the flow channel 31 of the guide assembly 3 under the action of the pressing member 4.

[0038] Referring to Figure 2 In optional embodiments, the connecting member 1 can be provided with a plurality of clamping holes 11, and each clamping hole 11 is used to clamp one pump core 21.

[0039] In optional embodiments, the pressing member 4 can be a block or a rod, and both sides of the pressing member 4 are provided with sliding blocks matched with the sliding grooves in the connecting member 1. The pressing action is realized by the up and down sliding of the sliding blocks in the sliding grooves. The direction of the sliding grooves on the connecting member 1 is perpendicular to the axial direction of the pump core 21, which ensures that the pressing direction accurately acts on the guide assembly 3.

[0040] In other optional embodiments, an elastic element such as a spring is used to connect the pressing part 41 and the connecting part 42. In the initial state, the pressing part 41 maintains a certain distance from the guide assembly 3 under the support of the elastic element. When an external force presses the pressing part 41, the elastic element is compressed, the pressing part 41 approaches the guide assembly 3 and exerts pressure, and after the external force is removed, the elastic element rebounds and the pressing part 41 returns to the original position.

[0041] Referring to Figure 4 In some embodiments, the pressing member 4 includes a pressing part 41 and a connecting part 42 connected together, and the connecting part 42 is arranged on both sides of the pressing part 41. Referring to Figure 1 The connecting part 42 is rotationally connected to the connecting member 1, the pressing part 41 abuts against one side of the guide assembly 3 away from the pump core assembly 2, and the connecting part 42 is used to rotate relative to the connecting member 1 to press the guide assembly 3. The connecting part 42 is located on both sides of the pressing part 41 and is rotationally connected to the connecting member 1. When the user presses the pressing part 41, the connecting parts 42 on both sides act as fulcrums to provide stable support for the pressing action, avoiding shaking and deviation during pressing, ensuring that the pressing part 41 acts on the guide assembly 3, so that the guide assembly 3 can smoothly press the pump core 21 each time, and the force on each pump core 21 is uniform, which helps to accurately and stably pump out the corresponding material. The rotationally connected mode utilizes the principle of leverage, and the connecting part 42 acts as a rotation fulcrum to effectively change the direction and size of the force. The user only needs a small downward pressure, and by virtue of the rotational relationship between the connecting part 42 and the connecting member 1, a larger pressing stroke and pressure can be generated in the pressing part 41, which easily drives the guide assembly 3 to extrude the pump core 21, reduces hand fatigue, and makes the operation more labor-saving. Even if the discharging structure 100 is used for a long time and frequently.

[0042] Please see Figure 4 In some embodiments, the surface of the pressing part 41 that abuts against the conductive component 3 is an arc surface 411. The arc surface 411 is used to roll along the surface of the conductive component 3 and press the conductive component 3 when the connecting part 42 rotates relative to the connecting member 1. The bottom of the pressing part 41 is set as an arc surface 411, which contacts the top plane of the conductive component 3. When the arc surface 411 contacts the plane, dynamic point-to-surface contact can be achieved, which can reduce the friction between the two.

[0043] Please see Figure 6 and Figure 7 In some embodiments, the length between the inlet 311 and outlet 312 of each flow channel 31 is the same. When the pressing member 4 drives the pump core 21 to pump the material into the flow channel 31, the different materials travel for the same amount of time within the flow channel 31, and at the outlet 312, multiple materials can be pumped out almost simultaneously. The same channel length makes the flow resistance of each flow channel 31 tend to be consistent. According to the principles of fluid mechanics, under the same pressure conditions, the same flow resistance results in a more stable and uniform flow velocity of the material. This avoids the situation where the flow velocity in some channels is too fast or too slow, leading to an imbalance in the output ratio, and ensures that the composition ratio of the multiple materials pumped out is always accurate and reliable.

[0044] In an optional implementation, the conductive component 3 may be in the shape of a cylinder, a polygonal prism, or the like.

[0045] In optional embodiments, the present application does not limit the shape and position of the multiple flow channels 31 within the conductive component 3. The flow channels 31 can be straight, polygonal, arc-shaped, curved, etc. The multiple flow channels 31 can be arranged side by side, in a ring, etc.

[0046] The specific structure of the flow guiding channel 31 will be described below:

[0047] Please see Figure 3In some embodiments, the guide component 3 has a prismatic shape, the pump core component 2 is located on the bottom surface of the guide component 3, and the inlet 311 of each guide channel is located at the corner 32 of the bottom surface of the guide component 3. The outlets 312 of all guide channels are located on the same outer surface 33 of the prismatic structure. The inlet 311 is located at the corner 32, allowing the material to enter the guide channel 31 relatively evenly at the corner of the bottom surface when the pump core component 2 pumps the material in. Compared to feeding at the center of the bottom surface or other locations, feeding at the corner 32 allows the material to be better dispersed in the initial stage of entering the guide channel 31, reducing local material accumulation or excessively high flow rates, which is beneficial for stable flow and uniform mixing within the guide channel 31. The fact that the outlets 312 of all guide channels 31 are located on the same outer surface 33 of the prismatic structure concentrates the discharge location in a specific area, facilitating unified control and guidance of the discharge. For example, a discharge valve, nozzle, or other discharge device can be installed on the outer surface 33 to facilitate accurate metering, mixing, or distribution of the discharged material.

[0048] Please see Figure 6 In some embodiments, the flow channel 31 includes a first flow channel 313, a second flow channel 314, and a third flow channel 315. The facet 32 ​​of the bottom surface of the guiding component 3 includes a first facet 321, a second facet 322, and a third facet 323. The first facet 321 is disposed opposite to the outer surface 33. The second facet 322 and the third facet 323 are respectively disposed on both sides of the first facet 321. The third facet 323 is disposed on the outer surface 33. The second facet 322 is along a first direction (e.g., Figure 6 The first direction (as shown in AA direction) is located between the first facet 321 and the third facet 323, and the first direction is the direction in which the first facet 321 and the outer surface 33 point to each other; the first flow channel 313 is along the positive direction of the first direction (e.g., Figure 6 Extending in the A+ direction, the inlet 311 of the first flow channel 313 is located at the first facet 321, and the outlet 312 of the first flow channel 313 is located in the middle of the outer side 33; the second flow channel 314 is located on both sides of the first flow channel 313, and the second flow channel 314 is bent sequentially along the second direction (as shown in the BB direction) and the first direction (as shown in the AA direction), the second direction intersects the first direction, the inlet 311 of the second flow channel 314 is located at the second facet 322, and the outlet 312 of the second flow channel 314 is located on the outer side 33, and is located on both sides of the outlet 312 of the first flow channel 313; the third flow channel 315 is located on both sides of the second flow channel 314, and the third flow channel 315 is bent sequentially along the negative direction of the first direction (as shown in the AA direction). Figure 6 As shown in A-direction) and the positive direction of the first direction (such as Figure 6The third flow channel 315 is arranged in a bending manner, the inlet 311 of the third flow channel 315 is arranged at the third face corner 323, the outlet 312 of the third flow channel 315 is arranged on the outer side surface 33 and is arranged on both sides of the outlet 312 of the second flow channel 314. The second flow channel 314 and the third flow channel 315 are arranged in different directions and can avoid interference with each other, thereby ensuring the independence of each other, maximizing the use of the three-dimensional space of the lead-through assembly 3, improving the space utilization, ingeniously adapting to the geometric shape of the regular polygonal prism, fully utilizing the limited space inside, and achieving miniaturization and portability of the outlet structure 100.

[0049] Please refer to Figure 7 In some embodiments, the third flow channel 315 arranged on both sides of the second flow channel 314 is at least partially arranged on the outer side surface 33, and the third flow channel 315 extends from both sides of the outlet 312 of the second flow channel 314 to the top and bottom of the outlet 312 of the first flow channel 313, so that the two outlets 312 of the third flow channel 315 are located at the top and bottom of the outlet 312 of the first flow channel 313 along the height direction of the outer side surface 33. The third flow channel 315 is partially arranged on the outer side surface 33, which utilizes the empty space of the outer side surface 33 of the lead-through assembly 3, avoids occupying the space inside the lead-through assembly 3 to layout the flow channel, and makes the overall structure more compact. Under the premise of not increasing the volume of the lead-through assembly 3, the layout requirement of multiple flow channels is met, which is helpful for the miniaturization design of the product.

[0050] The specific structure of the lead-through assembly 3 will be introduced below:

[0051] Please refer to Figure 3In some embodiments, the through component 3 comprises a shell 34 and a cover 35, the shell 34 is provided with a plurality of spaced flow guide grooves 341, the cover 35 is provided with a plurality of spaced flow guide protrusions 351, the cover 35 is detachably connected to the shell 34, so that the flow guide protrusions 351 cover the flow guide grooves 341 to jointly form the flow guide channel 31. Building flow guide grooves 341 and flow guide protrusions 351 on the shell 34 and the cover 35 respectively, compared with directly machining a complete flow guide channel 31 inside one integral part, the manufacturing difficulty is greatly reduced. The flow guide grooves 341 on the shell 34 can be completed by milling, injection molding and other conventional processes, and the flow guide protrusions 351 on the cover 35 are also relatively simple to process, without complex internal hollowing, drilling and other delicate operations, which helps to improve production efficiency, shorten processing cycle and reduce manufacturing cost, especially suitable for large-scale production scenarios. When the through component 3 needs to be cleaned, the detachable cover 35 design provides great convenience. After the cover 35 is removed, the flow guide grooves 341 are completely exposed, making it easy to clean the residual material, impurities and other long-term accumulated in the grooves, which can effectively prevent blockage, maintain the smoothness of the flow guide channel, ensure the stability and accuracy of the discharge, reduce equipment failures caused by channel blockage, and prolong the service life of the equipment. The flow guide protrusions 351 cooperate with the flow guide grooves 341 to form a tighter and more stable sealing structure compared to simple flat lamination. The protrusions embedded in the grooves increase the contact area and sealing path, reducing the risk of material leakage to adjacent channels, ensuring independent transportation of each material in its own channel, and maintaining the accuracy of the discharged ingredients.

[0052] Please refer to Figure 3 In some embodiments, the shell 34 comprises a main body 342 and an end part 343 connected thereto, and the cover 35 comprises a first cover 352 and a second cover 353 arranged at intervals, the main body 342 is provided with flow guide grooves 341, and the flow guide grooves 341 at least partially extend to the outer side 33 of the main body 342, please refer to Figure 3 and Figure 5 The first cover 352 is provided with flow guide protrusions 351, please refer to Figure 3The main body 342 is further provided with a first clamping groove 4321, the first cover 352 is provided with a first clamping block 3521, and the first clamping block 3521 and the first clamping groove 4321 are detachably connected. The end portion 343 is arranged on the outer side surface 33 of the main body 342, and the end portion 343 is arranged on the outer periphery of the discharging port 312 of the flow guide channel and the flow guide groove 341. The end portion 343 is further provided with a second clamping groove 3431, the second cover 353 is provided with a flow guide protrusion 351, the second cover 353 is provided with a second clamping block 3531, and the second clamping block 3531 and the second clamping groove 3431 are detachably connected. The flow guide groove 341 partially extends to the outer side surface 33 of the main body 342. Such a layout cooperates with the segmented cover of the first cover 352 and the second cover 353, so as to better adapt to complex space trends and shape requirements. The first cover 352 combines with the main body 342 to control the flow guide groove 341 of the main part, and the second cover 353 cooperates with the end portion 343 to accurately process the sealing and flow guiding of the periphery of the discharging port 312, so that the flow guide channel can not only match the overall shape of the flow guide assembly 3, but also guarantee the conveying function of the flow guide channel.

The first part 3522 is further provided with an avoiding groove 35221. The second part 3523 is provided with a first clamping block 3521, the second part 3523 is pressed on the first part 3522, the first clamping block 3521 passes through the avoiding groove 35221 and abuts against the outer periphery of the first part 3522, and the first clamping groove 4321 of the main body 342 is clamped. For the first cover 352, the first part 3522 directly abuts against the mounting step, so that the flow guide protrusion 351 of the first part 3522 is accurately embedded in the flow guide groove to realize sealing. Such close fitting can minimize the risk of material leakage. Then, the second part 3523 is pressed on the first part 3522, which is equivalent to applying an additional stable pressure to the first part 3522, further strengthening the sealing, ensuring that the material in the flow guide channel will not leak to the adjacent channel, and maintaining the independence and accuracy of the material conveying.

The third part 3532 of the second cover 353 is first matched and sealed with the outer side surface 33 of the main body part 342, and then the fourth part 3533 is abutted, which double guarantees the sealing performance of the key area around the discharge port 312. During discharging, the material body can be effectively prevented from seeping out.

[0055] In a second aspect, the embodiments of the present application further provide a discharging system, which comprises the discharging structure 100 of the first aspect.
