Detailed Implementation

[0024] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0025] In the description of this invention, non-limiting terms are used. Figure 1 The labels “front,” “back,” “up,” “down,” “left,” and “right” shown are used to facilitate understanding of this embodiment and are not intended to limit this application. Specifically, front and back represent the horizontal direction, left and right represent the vertical direction, and up and down represent the vertical direction.

[0026] The raw materials used in this application are diverse, and the device has a wide range of applications, including liquid raw materials of various viscosities (high-viscosity pastes / low-viscosity aqueous solvents). Centrifugal mixing is achieved in small containers using magnetic force, resulting in rapid, non-stratifying, non-foaming, and highly consistent mixing. Raw materials may include high-concentration color pastes, fragrances, single essential oils, skin-care active ingredients, liquid edible pigments, and liquid edible functional extracts. A base material, i.e., a basic carrier medium, may also be added before mixing, including but not limited to oily pastes, alcoholic solvents, aqueous solvents, skin-care base oils, and emulsions.

[0027] Therefore, in personalized or miniaturized application scenarios, this device can be used as a mixing device for cosmetic ingredients, food, nutritional products, beverages, and other ingredients.

[0028] like Figure 1 As shown, the raw material output device of this application includes a constant pressure device A200, a raw material pipe B10, and an injection valve C100. The raw material pipe B10 is used to contain liquid raw materials or raw materials. The upper part of the raw material pipe B10 is connected to the constant pressure device A200 for inputting constant pressure gas. The lower part of the raw material pipe B10 is connected to the injection valve C100 for injecting the raw materials therein.

[0029] Furthermore, Figure 1 The document also shows an air pump D100 connected to a constant pressure device A200. The air pump D100 generates gas which is input into the constant pressure device A200. The constant pressure device A200 can adjust the pressure to a set value as needed and maintain this pressure constant to act on the material inside the raw material pipe B10, ensuring the accuracy of the pressure generated by this air pressure acting on the raw material.

[0030] Figure 1 Since there are multiple raw material pipes B10, a gas distribution channel B201 can be set between the constant pressure device A200 and the raw material pipes B10 to achieve branched output of the constant pressure gas, ensuring that the gas pressure output to each raw material pipe B10 is consistent. Furthermore, Figure 1 The document also shows that multiple raw material pipes B10 are connected to a dispensing channel B202, which is connected to the outlet of each raw material pipe B10, forming a unified component that connects the outlets of all raw material pipes B10. This facilitates the integrated installation of the raw material pipes B10 and the unified output of each raw material. Each outlet of the dispensing channel B202 is also connected to multiple injection valves C100, thus enabling the integrated installation of multiple injection valves C100.

[0031] In practical implementation, in order to save installation space, the gas distribution channel B201 and the liquid distribution channel B202 can be integrated, corresponding to the gas-liquid conduction seat B20 below this application.

[0032] like Figures 2A to 2G As shown, this application provides a constant pressure device A200 that can provide stable air pressure. By connecting an air pump to the constant pressure device A200, the direct connection between the air pump and the raw material pipe is avoided. This allows the constant pressure device A200 to filter out the pulsation of the air pump operation. By outputting a stable airflow after being stabilized by the constant pressure chamber A2011 through the air outlet A2013, the "pockmarking" and "splashing" problems caused by air pressure fluctuations during the injection of raw materials (in this application, it is a short-term micro-injection, referred to here as point injection raw materials) can be solved from a physical perspective, so that the raw materials can be output stably.

[0033] In one embodiment, the constant pressure device A200 includes a constant pressure body A201 and a first switching valve A202 and a second switching valve A203 fixedly connected to the constant pressure body A201. The constant pressure body A201 has an air inlet port A2012 and an air outlet port A2013 on opposite sides, and a constant pressure chamber A2011 is disposed inside it. The air inlet port A2012 is connected to an external air pump and is also connected to the constant pressure chamber A2011 via the second switching valve A203. The air outlet port A2013 is connected to an external nozzle. When the injection material is required, the gas in the constant pressure chamber A2011 is output from the outlet port A2013; if the gas pressure in the constant pressure chamber A2011 is insufficient, the second switching valve A203 connects the inlet port A2012 and the constant pressure chamber A2011 to allow air intake; when the gas pressure in the constant pressure chamber A2011 reaches the predetermined gas pressure, the second switching valve A203 closes, stops the air intake, and the injection valve injects the material.

[0034] Furthermore, in this embodiment, as Figure 2A and Figure 2B As shown, the constant pressure body A201 has a pressure relief through hole A2015 on its upper side, and the pressure relief through hole A2015 is connected to the constant pressure chamber A2011 through the first switching valve A202. Figure 2B and Figure 2C As shown, the inner wall of the constant pressure chamber A2011 has a first through hole A2016 and a third through hole A2018 on the side facing the first switching valve A202 and the second switching valve A203. The first through hole A2016 is connected to the first switching valve A202, and the third through hole A2018 is connected to the second switching valve A203. The intake through hole A2012 has a fourth through hole A2019 connected to the second switching valve A203. The second switching valve A203 can connect the third through hole A2018 and the fourth through hole A2019, thereby connecting the intake through hole A2012 and the constant pressure chamber A2011. When using injected raw materials, the constant pressure device A200 detects the air pressure in the constant pressure chamber A2011. If the detected air pressure in the constant pressure chamber A2011 is less than the predetermined air pressure, the second switching valve A203 connects the air inlet port A2012 and the constant pressure chamber A2011, forming a pressure-boosting channel between the constant pressure chamber A2011 and the air inlet port A2012, increasing the air pressure in the constant pressure chamber A2011 to the predetermined air pressure. If the detected air pressure in the constant pressure chamber A2011 is greater than the predetermined air pressure, the first switching valve A202 connects the pressure relief port A2015 and the constant pressure chamber A2011, forming a pressure relief channel between the constant pressure chamber A2011 and the pressure relief port A2015, reducing the air pressure in the constant pressure chamber A2011 to the predetermined air pressure.

[0035] In this embodiment, as Figure 2C and Figure 2DAs shown, the first switching valve A202 has a first connecting hole A2021, a second connecting hole A2022, and a third connecting hole A2023 on the side facing the constant pressure body A201, which can be independently connected to each other. When the first connecting hole A2021 is connected to the second connecting hole A2022, the first switching valve A202 is in the closed state; when the first connecting hole A2021 is connected to the third connecting hole A2023, the first switching valve A202 is in the connected state. The first connecting hole A2021 is connected to the first through hole A2016, and the third connecting hole A2023 is connected to the second through hole A2017. When the first switching valve A202 is in the connected state, the first through hole A2016 is connected to the second through hole A2017, the pressure relief channel of the constant pressure device A200 is opened, and the air pressure in the constant pressure chamber A2011 is reduced.

[0036] In this embodiment, as Figure 2D As shown, the second switching valve A203 has a fourth connecting hole A2031, a fifth connecting hole A2032, and a sixth connecting hole A2033 on the side facing the constant pressure body A201, which can be independently connected to each other. When the fourth connecting hole A2031 is connected to the fifth connecting hole A2032, the second switching valve A203 is in the closed state; when the fourth connecting hole A2031 is connected to the sixth connecting hole A2033, the second switching valve A203 is in the connected state. The fourth connecting hole A2031 is connected to the third through hole A2018, and the sixth connecting hole A2033 is connected to the fourth through hole A2019. When the second switching valve A203 is in the connected state, the first through hole A2016 is connected to the second through hole A2017, the pressure boosting channel of the constant pressure device A200 is opened, and the constant pressure chamber A2011 is replenished with gas to boost its pressure. By opening and closing the first switching valve A202 and the second switching valve A203, the constant pressure chamber A2011 is depressurized by exhaust or pressurized by replenishment, thereby maintaining the air pressure in the constant pressure chamber A2011.

[0037] Furthermore, in this embodiment, the distance between the first connecting hole A2021 and the third connecting hole A2023 corresponds to the distance between the first through hole A2016 and the second through hole A2017, such that when the first switching valve A202 is connected to the constant pressure body A201, the first connecting hole A2021 is connected to the first through hole A2016, and the third connecting hole A2023 is connected to the second through hole A2017. The distance between the fourth connecting hole A2031 and the sixth connecting hole A2033 corresponds to the distance between the third through hole A2018 and the fourth through hole A2019, such that when the second switching valve A203 is connected to the constant pressure body A201, the fourth connecting hole A2031 can be connected to the third through hole A2018, and the sixth connecting hole A2033 can be connected to the fourth through hole A2019.

[0038] Furthermore, in this embodiment, as Figure 2C As shown, the constant pressure body A201 has at least one mounting hole A2010 on the side near the first switching valve A202 and the second switching valve A203. The constant pressure device A200 is fixedly connected to external equipment at the mounting hole A2010 using screws, bolts, or other fasteners. The first switching valve A202 and the second switching valve A203 are fixedly connected to the constant pressure body A201 using screws, bolts, or other fasteners. The constant pressure device A200 also includes an electrical terminal (not shown in the figure), which is electrically connected to an external power source to provide power to the constant pressure device A200. Specifically, the electrical terminal is electrically connected to the pressure sensor, the first switching valve A202, and the second switching valve A203, respectively, and provides them with power.

[0039] In this embodiment, as Figure 2B As shown, the constant pressure body A201 has a detection through-hole A2014 on the side opposite to the pressure relief through-hole A2015, which communicates with the constant pressure chamber A2011. A pressure sensor (not shown in the figure) is installed inside the detection through-hole A2014, which monitors the pressure in the constant pressure chamber A2011 in real time. The constant pressure device A200 also includes a controller A204 (not shown in the figure), which is electrically connected to the first switching valve A202, the second switching valve A203, and the pressure sensor. When the pressure sensor detects that the pressure in the constant pressure chamber A2011 is lower than the predetermined pressure, a signal is transmitted to the controller A204. The controller A204 then controls the first switching valve A202 to close and the second switching valve A203 to open, forming a pressure boosting channel to replenish the constant pressure chamber A2011. When the pressure in the constant pressure chamber A2011 is detected to be higher than the predetermined pressure, the controller A204 controls the first switching valve A202 to open and the second switching valve A203 to close, forming a pressure relief channel to reduce the pressure in the constant pressure chamber A2011. By monitoring the pressure in the constant pressure chamber A2011 in real time through the pressure sensor and controlling the opening and closing of the first switching valve A202 and the second switching valve A203 through the controller A204, the pressure in the constant pressure chamber A2011 can be stabilized at or close to the predetermined pressure, achieving dynamic pressure constancy.

[0040] In this embodiment, the constant pressure body A201 of the constant pressure device A200 is integrally molded. The length of the constant pressure body A201 is 63.50 mm, the width is 30.05 mm, and the height is 16.40 mm. It should be noted that the size and shape of the constant pressure body A201 in this embodiment are only an example of this application; in some other embodiments, such as... Figures 2E to 2G As shown, the size and shape of the constant pressure body A201 can be designed according to the actual application, and no specific limitation is made here.

[0041] In this embodiment, as Figure 2HAs shown, the constant pressure device A200 further includes: a switch driver A210 electrically connected to the controller A205; a first control switch A211, a second control switch A212, and a third control switch A213, all electrically connected to the switch driver A210; an intake valve A208 electrically connected to the second control switch A212; an outlet valve A209 electrically connected to the third control switch A213; and a power supply A214. The first control switch A211 is electrically connected to the air pump A207. The power supply is electrically connected to the air pump A207, the intake valve A208, and the outlet valve A209. The intake valve A208 is connected to the intake port A2012 and is used for... The air inlet port A2012 is controlled to open and close. The air outlet valve A209 is connected to the air outlet port A2013 and is used to control the opening and closing of the air outlet port A2013. The first control switch A211 is used to control the on and off of the air pump A207. The second control switch A212 is used to control the opening and closing of the air inlet valve A208 to control the opening and closing of the air inlet port A2012.

[0042] The control method of the constant pressure device A200 is described below. To better understand how the constant pressure device A200 of the above embodiments of this application automatically achieves constant pressure control, the control flow of the constant pressure device A200 of this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] According to one embodiment of this application, this application also provides a control method for a constant pressure device A200, such as... Figure 2I As shown, the method includes: step S1, in response to a target air pressure command, starting air pump A207 and air pressure sensor A206; step S2, monitoring the current air pressure, and controlling the opening and closing of the first switching valve and the second switching valve A203 respectively according to the current air pressure and the target air pressure; step S3, controlling the opening and closing of the first through hole A2016 and the second through hole A2017 according to the opening and closing of the first switching valve, and controlling the opening and closing of the third through hole A2018 and the fourth through hole A2019 according to the opening and closing of the second switching valve A203, so as to adjust the current air pressure in the constant pressure chamber A2011 to the target air pressure.

[0044] Therefore, the embodiments of this application achieve automated initialization of the constant pressure process by activating the air pump A207 and the air pressure sensor A206 in real time in response to the target air pressure command. Subsequently, the controller A205 continuously monitors the current air pressure in the constant pressure chamber A2011 and compares it with the target value, thereby intelligently controlling the opening and closing states of the first switching valve A202 and the second switching valve A203, and thus precisely adjusting the opening and closing of each ventilation channel. This control logic ensures that the air pressure in the constant pressure chamber A2011 can be quickly and accurately dynamically adjusted to the target value, significantly improving the response speed, stability, and automation level of pressure control, while reducing the complexity and intervention requirements of manual operation.

[0045] In this embodiment, step S3 includes: comparing the current air pressure and the target air pressure, wherein: if the current air pressure is greater than the target air pressure, controlling the first switching valve A202 to connect to connect the first through hole A2016 and the second through hole A2017, controlling the second switching valve A203 to close to close the third through hole A2018 and the fourth through hole A2019, so that the constant pressure chamber A2011 and the pressure relief through hole A2015 form a pressure relief circuit, adjusting the current air pressure to the target air pressure; or, if the current air pressure is less than the target air pressure, controlling the first switching valve A202 to close to connect the first through hole A2016 and the second through hole A2017, and controlling the second switching valve A203 to close the third through hole A2018 and the fourth through hole A2019, so that the constant pressure chamber A2011 and the pressure relief through hole A2015 form a pressure relief circuit, adjusting the current air pressure to the target air pressure; or, if the current air pressure is less than the target air pressure, controlling the first switching valve A202 to close to connect the first through hole A2016 and the second through hole A2017, and controlling the second switching valve A2017 to connect the first through hole A2018 and the second through hole A2019, and controlling the second switching valve A2016 to connect the second through hole A2017, and controlling the second switching valve A2018 to connect the second through hole A2019, and controlling the second through hole A2019 to connect the third through hole A2016 and the fourth through hole A2019, so that the constant pressure chamber A2011 and the pressure relief through hole A2019 form a pressure relief circuit, and adjusting the current air pressure to the target air pressure; or, if the current air pressure is less than the target air pressure, controlling the first switching valve A202 to close to connect the first through hole A2016 and the second through hole A2019, and controlling the second When through-hole A2016 and the second through-hole A2017 are closed, the second switching valve A203 is connected to connect the third through-hole A2018 and the fourth through-hole A2019, so that the constant pressure chamber A2011 and the air inlet through-hole A2012 form a pressure boosting circuit, adjusting the current air pressure to the target air pressure; or, if the current air pressure is equal to the target air pressure, the first switching valve A202 is closed to close the first through-hole A2016 and the second through-hole A2017, and the second switching valve A203 is closed to close the third through-hole A2018 and the fourth through-hole A2019.

[0046] The inventors discovered that raw materials of different viscosities require different pressure thresholds to achieve stable output. In this embodiment, the controller receives the user-inputted viscosity value of the raw material and controls the air pump A207 to output a specified pressure based on this viscosity value, so that the pressure in the constant pressure chamber can be controlled to the pressure value corresponding to the viscosity value of the raw material. This method enables the constant pressure device of this application to be suitable for the stable output of raw materials of different viscosities.

[0047] Therefore, the embodiments of this application, through real-time pressure comparison and corresponding electromagnetic switch valve control logic, achieve precise and efficient regulation of the air pressure in the constant pressure chamber A2011. When the air pressure is too high, the pressure relief circuit is automatically opened to exhaust air; when the air pressure is too low, the pressure boosting circuit is activated to replenish air; and when the target air pressure is reached, all circuits are closed to maintain stability. This closed-loop control strategy based on real-time feedback not only ensures that the air pressure can converge and stabilize at the target value quickly and accurately, but also effectively avoids frequent oscillations and energy waste in the device, significantly improving the reliability, response speed, and overall energy efficiency of constant pressure control.

[0048] In this embodiment, Figure 2I Based on the illustrated embodiments, as Figure 2J As shown, the control method of this application further includes: step S4, in response to the material unloading completion command, shutting off the air pump A207, controlling the first switch valve A202 to connect to connect the first through hole A2016 and the second through hole A2017, and controlling the second switch valve A203 to close to close the third through hole A2018 and the fourth through hole A2019; step S5, comparing the current air pressure with a preset low pressure threshold, and when the current air pressure is less than or equal to the preset low pressure threshold, controlling the first switch valve A202 to close to close the first through hole A2016 and the second through hole A2017, and controlling the second switch valve A203 to close to close the third through hole A2018 and the fourth through hole A2019.

[0049] Therefore, the embodiments of this application effectively ensure the safety and standby status of the device by executing intelligent venting and low-pressure monitoring processes after material unloading. Specifically, the air pump A207 is automatically shut down and the pressure relief passage is opened first, actively and quickly releasing the air pressure in the constant pressure chamber A2011 to a safe level. Subsequently, the controller A205 continuously monitors the air pressure, and only completely closes all valves when the air pressure drops below the preset low-pressure safety threshold. This design avoids equipment risks or malfunctions that may be caused by high pressure residue, and prevents excessive venting or frequent valve opening and closing through precise threshold judgment, thereby ensuring operational safety while optimizing energy consumption and extending the service life of key components such as valves. At the same time, the constant pressure device A200 of this application integrates automatic pressure relief logic, automatically venting the high pressure in the constant pressure chamber A2011 upon shutdown to prevent accidental splashing during maintenance or air pressure shock during restart.

[0050] Indicatively, such as Figure 2KAs shown, controller A205, based on the reading of air pressure sensor A206, controls the opening and closing combination of two electromagnetic switch valves to achieve closed-loop control in the following five stages: (1) Initial standby: all through holes are closed, air pump A207 is not working, and air pressure sensor A206 monitors at low frequency. (2) Pressure building and inflation: after receiving the current air pressure command, air pump A207 starts, controls the second switch valve A203 to open, the first switch valve A202 to close, and the constant pressure chamber A2011 is rapidly pressurized. (3) Constant pressure operation (pressure holding): when the air pressure in constant pressure chamber A2011 reaches the set target range, all through holes are closed, air pump A207 is in low-frequency standby, and the residual pressure in constant pressure chamber A2011 is used to supply materials smoothly and eliminate airflow pulsation. (4) Dynamic adjustment (PID / hysteresis control): Underpressure compensation: If the air pressure in the constant pressure chamber A2011 is lower than the preset lower limit air pressure threshold, the second switch valve A203 is opened and the first switch valve A202 is closed, and the constant pressure device A200 is opened to replenish air instantly; Overpressure correction: If the air pressure in the constant pressure chamber A2011 is higher than the preset upper limit air pressure threshold, the second switch valve A203 is closed and the first switch valve A202 is opened, and the constant pressure device A200 is opened to exhaust air instantly; This cycle is repeated to keep the air pressure in the constant pressure chamber A2011 locked in the set range. (5) Pressure relief and reset: After receiving the material unloading completion instruction, the air pump A207 stops, the second switch valve A203 is closed and the first switch valve A202 is opened to discharge the residual high pressure in the constant pressure chamber A2011 to atmospheric pressure to ensure safety.

[0051] In summary, compared to existing proportional valves or cylinder solutions that rely on physical displacement to achieve constant pressure, this application utilizes the millisecond-level switching action of an electromagnetic switching valve combined with sampling by a high-frequency pressure sensor A206. This allows for instantaneous response to pressure changes within the constant pressure chamber A2011, with dynamic compensation speeds far exceeding those relying on physical displacement. This enables high-frequency response and high-precision stable pressure. Furthermore, this application integrates intake, pressure relief, pressure stabilization, sensing, and multi-channel diversion functions into the main body A201, significantly saving space and making it particularly suitable for desktop automation equipment with strict size requirements. Moreover, the constant pressure device A200 of this application consists only of the main body A201 and two switching valves, without complex precision microchannels or easily worn mechanical components. Compared to precision proportional valves, the constant pressure device A200 of this application is easier to manufacture, has a very high mass production yield, is insensitive to air source cleanliness, and significantly reduces maintenance costs.

[0052] As described above, the constant pressure device A200 includes a constant pressure body A201, a first switching valve A202, and a second switching valve A203. The first switching valve A202 and the second switching valve A203 are arranged side-by-side on the same side of the constant pressure body A201 and are fixedly connected to it. An air inlet port A2012 and an air outlet port A2013 are provided on opposite sides of the constant pressure body A201. A constant pressure chamber A2011 is provided inside the constant pressure body A201, and the constant pressure chamber A2011 communicates with the air inlet port A2012 and the air outlet port A2013. This application controls the opening and closing of the first switching valve A202 and the second switching valve A203, ensuring that the internal air pressure of the constant pressure chamber A2011 is maintained at a predetermined pressure, thereby outputting a stable airflow after pressure stabilization. This effectively solves the problem of pitting and splashing caused by air pressure fluctuations in raw material output, enabling stable output of cosmetic pigments from the pigment device. Figures 3A to 3K As shown, the gas-liquid conduction module B100 adopts an integrated design, which integrates the dispersed gas supply pipes and raw material transmission pipes into one, significantly simplifying the pipeline layout, realizing a modular structure, and reducing assembly difficulty.

[0053] In this embodiment, as Figure 3A As shown, the gas-liquid conduction module B100 includes a gas-liquid conduction seat B20 and at least one raw material pipe B10, one end of which is detachably inserted into the gas-liquid conduction seat B20. Figure 3C As shown, the raw material pipe B10 has an air inlet B124 and an outlet B123 on the side near the gas-liquid conduit B20. The gas-liquid conduit B20 has multiple sets of gas-liquid channels inside, each set including an air supply channel and an outlet channel. When the raw material pipe B10 is inserted into the gas-liquid conduit B20, one end of the air supply channel is connected to the air supply device, and the other end is connected to the air inlet B124 of the raw material pipe B10. One end of the outlet channel is connected to the nozzle or mixing container, and the other end is connected to the outlet B123 of the raw material pipe B10. When the gas-liquid conduit module B100 is operating to supply raw materials, the gas supplied by the air supply device enters the raw material pipe B10 through the air supply channel and the air inlet B124. By compressing the raw materials stored in the raw material pipe B10, the raw materials flow sequentially through the outlet B123 and the outlet channel to the nozzle or mixing container. It should be noted that the number of gas-liquid channels corresponds to the number of raw material pipes B10. This embodiment only uses 6 sets of gas-liquid channels as an example for illustration, but this application does not limit the specific number.

[0054] In this embodiment, as Figures 3B to 3DAs shown, the raw material pipe B10 includes a shell B11, a storage pipe B12, a cover B13, and an inner plug B14. The shell B11 is cylindrical and has a raw material receiving cavity B111 inside. The storage pipe B12 is detachably disposed within the raw material receiving cavity B111. The cover B13 is disposed above the shell B11, i.e., at the end opposite to the gas-liquid conduction seat B20. The storage pipe B12 is used to store raw materials, and the inner plug B14 is slidably disposed inside the storage pipe B12 to squeeze the raw materials out. Specifically, as... Figure 3D As shown, the storage tube B12 includes a storage chamber B121 and an air supply chamber B122 that are isolated from each other, and an inner plug B14 is disposed in the storage chamber B121; the storage chamber B121 and the air supply chamber B122 are arranged side by side along the length of the storage tube B12, and the two are connected to each other at one end near the cover B13. The storage chamber B121 has a discharge port B123 at one end near the gas-liquid conduction seat B20, and the air supply chamber B122 has an air inlet B124 on the side where the discharge port B123 is located. When the raw material pipe B10 is inserted into the gas-liquid conduction seat B20, the discharge port B123 is connected to the discharge channel of the gas-liquid conduction seat B20, and the air inlet B124 is connected to the air supply channel. The gas from the air supply device enters the air supply chamber B122 through the air supply channel and the air inlet B124, and then enters the storage chamber B121 above it, acting on the inner plug B14 in the storage chamber B121. The inner plug B14 squeezes the raw material downward, so that the raw material enters the discharge channel through the discharge port B123, thus realizing the discharge.

[0055] Furthermore, in this embodiment, as Figure 3D As shown, the storage tube B12 is equipped with a discharge seal B15 at the discharge port B123 of the storage chamber B121. The discharge seal B15 is a flexible sealing object that can be punctured or drilled, such as a sealing diaphragm or sealing plug, and its shape and size are adapted to the shape and size of the discharge port B123. When the raw material tube B10 is not inserted into the gas-liquid conduit B20, the raw material is sealed and stored in the storage chamber B121 by the discharge seal B15. The storage tube B12 is equipped with an air inlet seal B16 at the air inlet B124 of the air supply chamber B122. The air inlet seal B16 is an O-ring B17 made of silicone, rubber, or other materials, and its shape and size are adapted to the shape and size of the air inlet B124. When the raw material tube B10 is inserted into the gas-liquid conduit B20, the part of the gas-liquid conduit B20 used for insertion fits tightly with the air inlet seal B16 to prevent gas leakage.

[0056] In this embodiment, as Figure 3C , Figure 3D and Figure 3FAs shown, an annular sealing protrusion B132 extends from the inner wall of the cover B13 toward the housing B11. Correspondingly, a sealing groove B125 is provided at one end of the storage tube B12 near the cover B13. The sealing groove B125 is located around the opening of the air supply chamber B122 and the storage chamber B121 at this end, and its shape and position correspond to the shape and position of the sealing protrusion B132. Furthermore, a sealing ring B17 is provided in the sealing groove B125, and the edge of the sealing protrusion B132 is embedded in the sealing groove B125 and presses against the sealing ring B17, thereby forming a sealed flow guiding cavity B18 between the sealing protrusion B132 and the sealing groove B125. The air supply chamber B122 and the storage chamber B121 are interconnected through this flow guiding cavity B18. The raw material pipe B10 forms a guide cavity B18 that connects the air supply cavity B122 and the storage cavity B121 through the cooperation of the sealing protrusion B132 on the cover B13 and the sealing groove B125 on the storage pipe B12. This achieves airtight communication between the air supply cavity B122 and the storage cavity B121, ensuring that the gas is stably transmitted to the top of the inner plug B14 and drives the inner plug B14 to smoothly descend and extrude the raw material.

[0057] Furthermore, in this embodiment, as Figure 3EAs shown, the inner plug B14 has a hollow structure and is made of soft materials such as plastic and silicone. It is slidably disposed within the storage cavity B121 and can squeeze the raw material downward when subjected to gas. The inner plug B14 includes a squeezing part B141, an abutting part B142, and a connecting part B143. Specifically, the squeezing part B141 is located at the end of the inner plug B14 near the discharge port B123, and is an arc-shaped protrusion facing the discharge port B123, which contacts the raw material stored in the storage cavity B121; the abutting part B142 is a hollow columnar part, and its sidewall abuts against the inner wall of the storage cavity B121. The connecting part B143 is disposed on the side of the squeezing part B141 opposite to the discharge port B123, and extends a cross-shaped skeleton from the center outward, with a connecting hole B144 at its center. Correspondingly, a limiting post B131 extends from the inner wall of the cover B13 toward the storage cavity B121. The position of the limiting post B131 corresponds to the position of the connecting hole B144. When the raw material pipe B10 is transported, the limiting post B131 abuts against the connecting hole B144 of the connecting part B143, so that the inner plug B14 will not be displaced during transportation, preventing the backflow of raw materials and other materials. When the gas entering the storage chamber B121 acts on the inner plug B14, the extrusion part B141 is forced downward to squeeze the raw material, thereby discharging the raw material from the outlet B123. At the same time, if there is air between the extrusion part B141 and the raw material, the inner plug B14 will deform due to the air during the extrusion process, causing a gap to appear between the abutment part B142 and the inner wall of the storage chamber B121. The air between the extrusion part B141 and the raw material will be discharged to the other side through the gap. When there is no air, the skeleton-type joint part B143 will restore the inner plug B14 to its original shape, forming a seal.

[0058] In this embodiment, as Figures 3G to 3N As shown, the gas-liquid conduit B20 includes a plug-in portion B21, a conduit portion B22, and a diverter portion B23. The plug-in portion B21 is located above the conduit portion B22, and the raw material pipe B10 is plugged into the plug-in portion B21. The conduit portion B22 has at least one gas supply channel and at least one discharge channel inside. One end of any gas supply channel is connected to the diverter portion B23, and the other end is connected to the plug-in portion B21. The diverter portion B23 is connected to the gas supply device, and gas enters each gas supply channel through the diverter portion B23, thereby entering each raw material pipe B10 through the plug-in portion B21. It should be noted that in this embodiment, there are six gas supply channels and six discharge channels, but in some other examples, other numbers may be used.

[0059] Specifically, in this embodiment, such as Figure 3GAs shown, the insertion part B21 is provided with multiple insertion positions for inserting the raw material tube B10. Each insertion position extends upward (i.e., vertically to the gas-liquid conduction module B100) with a hollow first insertion tube B211 and a second insertion tube B212. The lower end of the inner channel of the first insertion tube B211 is connected to the air supply channel in the conduction part B22, and the upper end of its inner channel is connected to the air inlet B124 of the raw material tube B10. The lower end of the inner channel of the second insertion tube B212 is connected to the discharge channel in the conduction part B22, and the upper end of its inner channel is connected to the discharge outlet B123 of the raw material tube B10. When the raw material pipe B10 is inserted into the connector B21, the first connector B211 is inserted into the air inlet B124, connecting the air inlet B124 and the air supply channel, thereby connecting the air supply chamber B122 and the air supply channel of the raw material pipe B10 to achieve air supply; the second connector B212 is inserted into the discharge port B123, connecting the discharge port B123 and the discharge channel, thereby connecting the material storage chamber B121 and the discharge channel of the raw material pipe B10 to achieve material discharge. By setting the connector position, the operation of using or replacing the raw material pipe B10 is faster and easier, enhancing the user experience.

[0060] Furthermore, such as Figures 3G to 3I As shown, the end of the second insertion tube B212 that connects to the raw material tube B10 has an inclined cut, forming a sharp piercing end. When the raw material tube B10 is connected to the gas-liquid conduit B20, the second insertion tube B212 is inserted into the outlet B123. The tip of its inclined cut first contacts and pierces the sealing diaphragm or sealing plug provided inside the outlet B123. As the insertion depth increases, the second insertion tube B212 gradually pushes open the pierced seal, making the outlet B123 connected to the discharge channel.

[0061] In this embodiment, as Figure 3G As shown, the conductive part B22 includes a first conductive part B221 and a second conductive part B222 stacked together. Specifically, as... Figure 3N As shown, the first guiding part B221 has multiple air supply channels inside, including a first air supply channel B2211, a second air supply channel B2212, and a third air supply channel B2213 arranged side by side along the longitudinal direction. Figure 3LAs shown, taking the first air supply channel B2211 as an example, its end near the branch section B23 is connected to the branch section B23, and the first air supply channel B2211 communicates with the branch section B23 at this end; its other end away from the branch section B23 bends upward and communicates with the bottom end of the corresponding internal channel of the first insertion pipe B211 provided on the insertion part B21, so that the branch section B23 is connected to the internal channel of the first insertion pipe B211 through the first air supply channel B2211. Similarly, the second air supply channel B2212 is connected to the branch section B23 at its end near the branch section B23, and the other end bends upward and communicates with the bottom end of the corresponding internal channel of the first insertion pipe B211 provided on the insertion part B21; the third air supply channel B2213 is connected to the branch section B23 at its end near the branch section B23, and the other end bends upward and communicates with the bottom end of the internal channel of the first insertion pipe B211 provided corresponding to the insertion position. Figure 3N As shown, inside the first guiding section B221, adjacent to the first air supply channel B2211, the second air supply channel B2212, and the third air supply channel B2213, there are correspondingly arranged first discharge channels B2214, second discharge channels B2215, and third discharge channels B2216 with the same orientation. Figure 3K As shown, taking the first discharge channel B2214 as an example, its end facing away from the diversion section B23 bends upwards and connects to the bottom end of the channel inside the second insertion pipe B212 corresponding to the insertion position. Its other end connects to a nozzle or mixing container. Similarly, the second discharge channel B2215 bends upwards at one end facing away from the diversion section B23 and connects to the bottom end of the channel inside the second insertion pipe B212 corresponding to another insertion position; the third discharge channel B2216 bends upwards at one end facing away from the diversion section B23 and connects to the bottom end of the channel inside the second insertion pipe B212 corresponding to another insertion position.

[0062] like Figure 3G and Figure 3M As shown, the second guiding section B222 is located at the upper end of the first guiding member near the diverting section B23, and has multiple air supply channels inside, including a fourth air supply channel B2221, a fifth air supply channel B2222, and a sixth air supply channel B2223 arranged longitudinally side by side. Similar to the first guiding section B221, as... Figure 3F As shown, the ends of the fourth air supply channel B2221, the fifth air supply channel B2222, and the sixth air supply channel B2223 near the branch section B23 are all connected to the branch section B23, while the ends away from the branch section B23 are bent upwards and connected to the internal channels of the first plug-in pipe B211 provided at the corresponding plug-in positions. Figure 3E and Figure 3GAs shown, inside the second guiding section B222, adjacent to the fourth air supply channel B2221, the fifth air supply channel B2222, and the sixth air supply channel B2223, there are corresponding fourth discharge channels B2224, fifth discharge channels B2225, and sixth discharge channels B2226, each with the same orientation. The ends of the fourth discharge channels B2224, fifth discharge channels B2225, and sixth discharge channels B2226 that are away from the diversion section B23 are bent upwards and communicate with the internal channels of the second insertion pipe B212 located at the corresponding insertion positions.

[0063] As can be seen from the above description, the gas-liquid conduit B20 of this application integrates multiple gas supply channels and multiple material discharge channels inside. While ensuring gas supply and material discharge, it completely integrates the originally exposed gas pipes and liquid pipes into the rigid module, realizing the "invisibility" and "integration" of the gas-liquid pipelines, greatly simplifying the internal space layout of the equipment, and making the overall structure more concise and compact.

[0064] In this embodiment, as Figure 3J and Figure 3L As shown, the diversion section B23 is located in front of the guiding section B22, and has a diversion cavity B231 inside. An air supply port B232, communicating with the diversion cavity B231, is provided on the side wall opposite to the guiding section B22. The air supply port B232 is used to connect to the air supply mechanism to supply air to the gas-liquid guiding module B100. The diversion section B23 has multiple through holes on its side wall near the guiding section B22, through which the air supply channels of the guiding section B22 communicate with the diversion cavity B231. When the gas-liquid guiding module B100 is running, the air supply mechanism supplies air to the diversion cavity B231 through the air supply port B232. After entering the diversion cavity B231, the gas can be diverted into multiple air supply channels, thereby entering the raw material pipe B10 and extruding the raw material.

[0065] In this embodiment, as Figure 3H As shown, the gas-liquid conduction module B100 also includes a circuit board B30, which is disposed between the conduction part B22 and the insertion part B21. The circuit board B30 is provided with multiple position detection elements B31, such as spring pins, whose positions correspond to the insertion positions on the insertion part B21. The insertion part B21 has a first detection through hole B213 at the position corresponding to the position detection element B31, through which the top end of the position detection element B31 passes and protrudes. Correspondingly, the raw material tube B10 has a fitted copper sheet (not shown in the figure) at its bottom. During the insertion process of the raw material tube B10, the top end of the position detection element B31 contacts and conducts with the copper sheet, at which point it is detected that the raw material tube B10 has been inserted into the predetermined position.

[0066] In this embodiment, as Figure 3HAs shown, the gas-liquid conduction module B100 also includes a liquid level detector (not shown in the figure), which is a Hall sensor used to detect the remaining amount of raw material in the raw material tube B10. A second detection through-hole B214 is provided on the plug-in part B21, and the liquid level detector passes through the second detection through-hole B214 and is electrically connected to the circuit board B30. A magnet is provided in the inner plug B14 of the raw material tube B10. The liquid level detector can detect the remaining amount of raw material in the raw material tube B10 by sensing the position of the magnet, and is used to remind the user to replace the liquid in time when the liquid level in the raw material tube B10 is insufficient. Furthermore, different reminder liquid levels can be set by adjusting the relative position of the liquid level detector and the bottom of the side wall of the raw material tube B10. In this embodiment, the liquid level reminder is set to remind when the liquid level in the tube is 10% remaining. If the liquid level detector is set further away from the bottom of the raw material tube 30 in the vertical direction, the reminder liquid level can be adjusted to a remaining liquid level greater than 10%. In some other embodiments, the level detector may also be an infrared beam sensor, and the wall of the raw material pipe B10 is a transparent wall. The need to replace the raw material pipe B10 is determined by detecting whether the inner plug B14 blocks the light.

[0067] In this embodiment, the gas-liquid conduction module B100 is provided with sealing rings B17 at multiple sealing connections. The shape and size of each sealing ring B17 are adapted to the shape and size of the sealing connection, thereby enhancing the airtightness of the connection and preventing gas leakage.

[0068] In this embodiment, as Figure 4A , Figure 4B and Figure 4CAs shown, the injection valve C100 includes a valve body C101, an electromagnetic drive assembly C102, a striker C103, and a liquid discharge assembly C104. It is connected to the discharge channel 4022 of the gas-liquid conduction section 401 and is used to quantitatively inject the raw material extruded from the raw material pipe 30 into the container or mixing device. The valve body C101 has a valve body receiving cavity inside. The electromagnetic drive assembly C102 includes a magnet C1021 and a magnetic conductor C1022. The magnet C1021 surrounds the valve body C101, and the magnetic conductor C1022 is disposed in the valve body receiving cavity. The striker C103 is disposed in the valve body receiving cavity, and the first end of the striker C103 is connected to the first end of the magnetic conductor C1022. The liquid discharge assembly C104 includes a liquid discharge housing C1041. The liquid discharge housing C1041 has a liquid discharge chamber C10411 that communicates with the valve body receiving cavity. The liquid discharge housing C1041 has a valve body inlet C10412 and a valve body outlet C10413 that communicate with the liquid discharge chamber C10411. The second end of the striker C103 penetrates into the liquid discharge chamber C10411 and is close to the valve body outlet C10413. The injection valve C100 utilizes an electromagnetic drive component C102 to directly drive the impact pin C103 through electromagnetic induction and a spring C107, ejecting the raw material entering the outlet chamber C10411. Compared to piezoelectric ceramic injection, the electromagnetically driven injection valve C100 in this application eliminates the need for expensive and complex multi-layered stacked piezoelectric ceramics, significantly reducing manufacturing costs. Simultaneously, the electromagnetic drive process is smooth, with minimal impact and a long service life, avoiding the severe mechanical noise generated by the instantaneous deformation of piezoelectric ceramics, thus significantly improving the user experience in civilian applications. Compared to cylinder-driven valves, the injection valve C100 of this application eliminates the need for a pneumatic system requiring a high-pressure air source, fundamentally eliminating safety hazards such as cylinder explosion and pipe detachment caused by high-pressure gas. Furthermore, its structure is more compact and simple, requiring no complex external pneumatic circuit devices, making it more suitable for safe and convenient deployment and use in civilian environments such as shopping malls and homes. Furthermore, the injection valve C100 of this application utilizes an electromagnetic drive assembly C102, composed of a magnet C1021 and a magnetic conductor C1022, to precisely control the up-and-down movement of the striking pin C103 within the valve body receiving cavity of the valve body C101. This precisely regulates the injection volume of the raw material from the valve body inlet C10412 through the liquid outlet cavity C10411 to the valve body outlet C10413. This injection valve C100, capable of precisely controlling the injection volume of raw materials, eliminates the traditional method of mixing relying on manual experience, achieving precise and efficient mixing of raw materials. This effectively ensures the quality of the mixed cosmetics and improves the user experience.

[0069] Specifically, in this embodiment, such as Figure 4BAs shown, valve body C101 includes a first valve body C1011 and a second valve body C1012. The first valve body C1011 is located on the side of the second valve body C1012 away from the liquid outlet chamber C10411. The first valve body C1011 has a first valve body receiving chamber C10111, and the second valve body C1012 has a second valve body receiving chamber C10121. The second valve body receiving chamber C10121 is connected to the first valve body receiving chamber C10111 and the liquid outlet chamber C10411, respectively. Among them, the striking pin C103 is disposed in the second valve body receiving chamber C10121; the magnet C1021 surrounds the periphery of the first valve body C1011; the magnetic conductor C1022 is disposed in the first valve body receiving chamber C10111, and the first end of the magnetic conductor C1022 is connected to the first end of the striking pin C103. When the injection valve C100 is energized, the magnet C1021 drives the magnetic conductor C1022 to move upward in the first valve body receiving cavity C10111, which in turn drives the impact pin C103 to move upward in the valve body receiving cavity. When the injection valve C100 is de-energized, the magnet C1021 moves downward in the first valve body receiving cavity C10111, which in turn drives the impact pin C103 to move downward in the valve body receiving cavity, thereby ejecting the raw material from the valve body outlet C10413.

[0070] Furthermore, such as Figure 4B , Figure 4C and Figure 4F As shown, the liquid dispensing assembly C104 also includes a nozzle C1042, which is connected to the valve body outlet C10413 of the liquid dispensing housing C1041. The inner wall of the nozzle C1042 contacts the second end of the impact pin C103. The nozzle C1042 has a spray port C10421 communicating with the liquid dispensing chamber C10411, and the inner wall of the nozzle C1042 is adapted to the second end of the impact pin C103. In the non-energized state, relying on the preload of the spring C107 and the gravity of the impact pin C103, the second end of the impact pin C103 is tightly fitted to the inner wall of the nozzle C1042, achieving a natural seal. The cross-section of the nozzle C1042 gradually increases from the spray port C10421 to the valve body outlet C10413. By setting a nozzle C1042 with a gradually narrowing cross-section connected to the liquid outlet housing C1041, and precisely fitting its inner wall with the ball head at the second end of the impact pin C103, when the impact pin C103 moves downward to contact the inner wall of the nozzle C1042, the second end of the impact pin C103 can completely enter and block the injection port C10421 at the end of the nozzle C1042, forming a sealed cavity in the liquid outlet chamber C10411. The second end of the impact pin C103 completely occupies the internal space of the nozzle C1042, spraying out the trace amount of liquid remaining in the injection port C10421. At this time, there is no residue on the outside of the nozzle C1042 and no dead corners inside, effectively preventing high-concentration raw materials from drying and clogging at the nozzle C1042, ensuring the smoothness and reliability of the injection valve C100 during long-term operation.

[0071] Furthermore, such as Figure 4E As shown, the injection valve C100 also includes an electrical connection line C114, which is connected to the magnet C1021. The electrical connection line C114 is connected to an external power source. This method eliminates the need for a high-pressure air source, reducing the risk of engine failure in civilian environments. The overall structure is driven by low-voltage DC electricity, making it safe and reliable.

[0072] Furthermore, such as Figure 4B and Figure 4C As shown, the injection valve C100 also includes a second limiting post C105, which is spaced apart from the second end of the magnetic conductor C1022 to limit the movement distance of the magnetic conductor C1022 within the first valve body receiving cavity C10111. Through this arrangement, the second limiting post C105 within the first valve body receiving cavity C10111 can precisely limit the upward movement distance of the magnetic conductor C1022 each time, thereby achieving rigid limiting of the return end point of the impact pin C103. This design can precisely limit the upward movement range of the magnetic conductor C1022, ensuring the repeatability and positioning accuracy of each reciprocating motion of the impact pin C103, and guaranteeing the consistency and stability of the injection flow rate.

[0073] Furthermore, the distance between the second limiting post C105 and the second end of the magnetic conductor C1022 is 0.1mm-1.5mm, which helps to precisely control the amount of liquid discharged within 0.1mg-5mg, maintaining the stability of the trace liquid discharge. It should be noted that the precise liquid discharge control of the injection valve C100 is also related to the size of the side that contacts the inner wall of the liquid discharge chamber C10411, the size of the liquid discharge chamber C10411, the size of the injection port C10421 of the nozzle C1042, the density and viscosity of the liquid raw material, etc., which are not specifically limited here.

[0074] Furthermore, such as Figure 4CAs shown, the injection valve C100 also includes a fixing member C106 and a spring C107. The fixing member C106 is disposed on the side of the second valve body receiving cavity C10121 near the first valve body receiving cavity C10111. The spring C107 is sleeved around the first end of the firing pin C103, and the first end of the spring C107 is connected to the fixing member C106. When the firing pin C103 moves upward in the valve body receiving cavity, the second end of the spring C107 is compressed towards its first end. By sleeved with the spring C107 on the firing pin C103, the firing pin C103 can compress the spring C107 and accumulate elastic potential energy when it moves upward. When the electromagnetic drive assembly C102 is de-energized and the magnetic field disappears, the compressed spring C107 will instantly release its stored energy (i.e., instantaneous impact force), providing a strong additional impact force for the downward movement of the firing pin C103. This design significantly increases the instantaneous velocity and impact energy of the impact pin C103 during its descent, thereby enabling the "physical cutting" of high-viscosity fluids and effectively solving the problem of raw materials in cosmetics and skincare products easily sticking to the nozzle C1042 and forming strings. In addition, compared to the loud mechanical knocking noise of piezoelectric ceramic drives, this application reduces the noise generated during use through a balanced design of electromagnetic force and spring C107 force.

[0075] Furthermore, such as Figure 4B and Figure 4D As shown, the injection valve C100 also includes a first sealing element C108, which is disposed at one end near the second valve body receiving cavity C10121 and the opening of the liquid outlet cavity C10411, and is adapted to the opening. The first sealing element C108 has an opening C1081, which is adapted to the corresponding position of the striking pin C103, for allowing the striking pin C103 to pass through the opening C1081 from the second valve body receiving cavity C10121 to the liquid outlet cavity C10411. By installing a first sealing element C108 at the opening of the liquid outlet chamber C10411, which is compatible with the opening of the chamber, a physical isolation structure is constructed to completely isolate the liquid outlet chamber C10411 from the second valve body receiving chamber C10121. This prevents raw materials from seeping into the first valve body receiving chamber C10111 and the second valve body receiving chamber C10121 when the striking pin C103 moves downward at high speed, protecting the electromagnetic drive assembly C102 from corrosion by the raw materials and ensuring the long-term stability and lifespan of the electromagnetic drive assembly C102. At the same time, the matching design of the opening C1081 of the first sealing element C108 with the striking pin C103 ensures the smooth movement of the striking pin C103, so that its attraction and impact actions are not affected.

[0076] Furthermore, in this embodiment, the side of the first sealing member C108 facing away from the outlet cavity C10411 is adapted to the inner wall of the second valve body receiving cavity C10121 that it contacts, and as... Figure 4DAs shown, the first sealing element C108 includes an integrally formed first protrusion C1082, an extension C1084, and a second protrusion C1083. The first protrusion C1082 and the second protrusion C1083 are disposed on opposite sides of the extension C1084. The first protrusion C1082 is perpendicular to the extension C1084, and the second protrusion C1083 is also perpendicular to the extension C1084. The first protrusion C1082 is connected to the inner wall of the outlet cavity C10411. The extension C1082... One side of the first sealing member C108 is connected to the cross-section of the outlet cavity C10411, and the other side of the second protrusion C1083 and the extension C1084 is connected to the inner wall of the second valve body receiving cavity C10121 (since the side of the first sealing member C108 facing away from the outlet cavity C10411 is adapted to the inner wall of the second valve body receiving cavity C10121 it contacts, the inner wall of the first sealing member C108 and the inner wall of the second valve body receiving cavity C10121 it contacts is also vertical). With the above configuration, the first sealing member C108 adopts a right-angle structure design consisting of the integrally formed first protrusion C1082, extension C1084 and second protrusion C1083, wherein the extension C1084 and the second protrusion C1083 are perpendicular to each other, and the side of the first sealing member C108 facing away from the outlet cavity C10411 is also vertically adapted to the inner wall of the second valve body receiving cavity C10121. This right-angle configuration ensures that when the striker C103 moves upward under electromagnetic drive, the extension C1084 that contacts the inner wall of the second valve body receiving cavity C10121 will be stopped by the downward force of the inner wall of the second valve body receiving cavity C10121, thereby enhancing the stability of the first seal C108.

[0077] Furthermore, such as Figure 4B and Figure 4CAs shown, the injection valve C100 also includes a first fastener C109, which is sleeved at the connection between the second valve body C1012 and the outlet housing C1041. The first inner wall of the first fastener C109 is adapted to the outer surface of the second valve body C1012 to which it is connected, and the second inner wall of the first fastener C109 is adapted to the outer surface of the outlet housing C1041 to which it is connected. Further, as shown in the figure, the inner wall of the first fastener C109 in contact with the outer surface of the second valve body C1012 and the inner wall in contact with the outer surface of the outlet housing C1041 are less than 180 degrees apart. This design allows the fastener to hook the outlet assembly C104 upwards, preventing the outlet assembly C104 from falling off due to the strong movement of the striker C103. With the above-mentioned configuration, a first fastener C109 is added to the periphery of the connection between the second valve body C1012 and the liquid outlet housing C1041, which effectively strengthens the tightness and structural strength of this key connection part. It can effectively prevent the second valve body C1012 and the liquid outlet housing C1041 from loosening or even separating under the continuous impact force generated by the high-speed reciprocating motion of the impact pin C103, ensuring the long-term stability and sealing integrity of the overall structure of the injection valve C100, and avoiding liquid leakage or performance degradation caused by connection failure.

[0078] Furthermore, such as Figure 4B and Figure 4F As shown, the liquid outlet assembly C104 also includes a second fastener C1043, which is sleeved on the outer surface of the liquid outlet housing C1041 near the nozzle C1042. The second fastener C1043 has an opening at the position corresponding to the nozzle C1042. By sleeved the second fastener C1043 on the outer surface of the liquid outlet housing C1041 near the nozzle C1042, and ensuring that its opening precisely corresponds to the valve body outlet C10413 or the nozzle C1042, the structural stability of the nozzle C1042 is enhanced when subjected to the high-frequency, high-impact reciprocating impact of the striking pin C103. This effectively prevents the nozzle C1042 from undergoing micro-displacement, loosening, or deformation due to long-term impact, ensuring the precise alignment of the jet flow channel.

[0079] Furthermore, such as Figure 4A and Figure 4B As shown, a protective sleeve C110 is fitted around the magnet C1021. A fastening tube C111 is fitted around the end of the limiting post facing away from the magnet C1022. Inside the fastening tube C111, a fastening post C112 is also provided, which contacts the second limiting post C105. A connector C113 is fitted around the end of the fastening tube C111 away from the limiting post. The connector C113 has a connecting hole C1131, which is used for connecting external equipment to the injection valve C100. Further, as... Figure 4A and Figure 4BAs shown, a fixing sleeve C1044 surrounds the outlet housing C1041 corresponding to the valve body inlet C10412. The fixing sleeve C1044 has a fixing hole C10441 opposite to the valve body inlet C10412 for communication with the raw material device. Through this structure, a protective sleeve C110 is provided around the magnet C1021, providing effective physical protection and positioning for the magnet C1021, preventing damage or displacement during assembly or vibration. Simultaneously, a fastening tube C111 with an internal fastening post C112 is provided at the end of the second limiting post C105 facing away from the magnet C1022. A stable and reliable external connection structure is constructed through the connecting piece C113 and the connecting hole C1131 fitted outside the tube. This structural design significantly enhances the axial positioning accuracy and overall rigidity of the key moving component (impact pin C103) inside the injection valve C100, effectively suppressing radial sway or end disturbance of the impact pin C103 during high-frequency reciprocating motion, ensuring the linearity and consistency of the impact action.

[0080] It should be noted that, without considering cost, piezoelectric ceramics can replace the electromagnetic drive component C102 to realize the up-and-down movement of the striker C103; the impact force of the striker C103 moving downward can also be increased by increasing air pressure or magnetic spring C107, which is not specifically limited here.

[0081] Correspondingly, such as Figure 4G As shown, a PWM signal is used to control the magnet C1021 in the injection valve C100 to control its opening and closing. High voltage indicates closure, and low voltage indicates opening. Within the first cycle T of the PWM signal, the high voltage lasts for T1, and the low voltage lasts for T2. Therefore, the injection valve C100 completes one discharge operation during the closed duration T1. After the open duration T2, the second and third closing and opening operations follow the same sequence. Therefore, Figure 4G The example involves controlling the output of three single-droplet raw materials. Within one PWM signal cycle T, the ratio between the high voltage duration T1 and the low voltage duration T2 can be adjusted as needed to adapt to different raw material characteristics.

[0082] Based on Table 1 below, this application selected a blue pigment raw material for testing. The duration of the high voltage of the PWM signal is within the controllable range of T1: 3ms-100ms. The output quality accuracy is 0.1mg-5mg, with an error rate of less than 2%. The operating limit distance of the valve body is 0.1mm-1.5mm, and the spring force range for generating the jet is 10N-30N.

[0083] Table 1 Test Data for Controlled Output of Pigment Raw Materials

[0084] In summary, this invention discloses a raw material output device, comprising: a raw material pipe for containing raw materials; a constant pressure device connected to the raw material pipe for inputting constant pressure gas into the raw material pipe to pressurize the raw materials; and an injection valve connected to the outlet of the raw material pipe for ejecting the raw materials. This application applies adjustable and stable pressure to the raw materials through the constant pressure device, and precisely controls the quality of the raw materials output from the raw material pipe through the injection valve. Furthermore, it employs a gas-liquid conduit to achieve integrated pressure supply and raw material output for multiple raw material pipes, which is beneficial for the miniaturization of the device. Therefore, this device can be used for precise control of raw material output in various application scenarios and has wide applicability.
