Description

Technical Field

[0001] The invention relates to the technical field of oil injection, in particular to a two-way oil injection device for an atomizer. Background Art

[0002] An electronic atomizer is a device that atomizes tobacco oil by means of high temperature, high pressure or ultrasound. During its automated production process or after the tobacco oil is consumed, tobacco oil needs to be injected into the electronic atomizer. Existing electronic atomizers usually use an automated injection structure to inject oil, using an oil supply pipeline to transport tobacco oil from an oil supply barrel to an injection module, and then inject it into the atomizer through an injection needle of the injection module.

[0003] However, existing oil injection modules generally adopt a one-way oil injection design. Although this design can achieve efficient oil injection for specific types of atomizers, it is unable to cope with the increasingly diverse atomizer products on the market.

[0004] There are many types of atomizer products on the market. When designing each atomizer, the direction of the oil filling hole is determined according to its functional requirements, user experience, aesthetics and other factors. Some atomizers have oil filling holes facing upwards, which is convenient for users to directly inject e-liquid from above; some face downwards to adapt to specific product structures or usage scenarios. This diversity of oil filling hole directions puts higher adaptability requirements on the oil filling module.

[0005] However, the existing oil injection modules can often only adapt to atomizers with one oil injection hole orientation. When the product specifications need to be changed on the production line, or the customer customizes an atomizer with a special oil injection hole orientation, the original oil injection module may not be able to meet the needs. At this time, the manufacturer has to invest resources to redesign and develop a new oil injection module to match the new atomizer style. This process is not only time-consuming and labor-intensive, but also greatly increases production costs. What's more serious is that with the increase in product types, the number and types of oil injection modules required will continue to increase, which will take up a lot of production space and reduce the overall efficiency of the production line. At the same time, frequent replacement of oil injection modules will also have an adverse effect on the stability and continuity of the production line, further increasing production costs and management difficulties.

DETAILED DESCRIPTION

[0021] See also Figure 1-11 The present invention is related to a two-way oil injection device for an atomizer, comprising a working box; A first atomizer oil filling fixture 4, which is detachably mounted on the top of the working box, and a first oil filling hole 412 is provided at the bottom of the first atomizer oil filling fixture 4; The oil injection system is built into the working box, and includes an oil supply module 31, an oil injection module 32 and a hot air module 33. The oil supply module 31 is connected to the oil injection module 32 and realizes oil supply. The hot air module 33 is connected to the oil injection module 32 and provides a hot air source to the oil injection module 32. The oil injection module 32 is provided with an upward injection needle 324 and a downward injection needle 320. A first driving part 21, the first driving part 21 is drivingly connected to the oil injection system, wherein the first driving part 21 drives the oil injection system to move along the spatial X-axis and the spatial Y-axis directions; The second driving part 22 (linear electric push rod) drives the first driving part 21 and the oil injection system to move up and down, and makes the upward injection needle 324 pass through or exit the first oil injection hole 412 .

[0022] The second atomizer oil filling fixture 5 is detachably mounted in the working box, and a second oil filling hole is arranged on the top of the second atomizer oil filling fixture 5. The third driving unit 23 (linear electric push rod) drives the second atomizer oil filling fixture 5 to move up and down, and makes the downward injection needle 320 pass through or exit the second oil filling hole.

[0023] The above scheme has the beneficial effect that the device realizes the up and down bidirectional oil injection function of the atomizer by arranging the upward injection needle 324 and the downward injection needle 320 in the same body. This makes it unnecessary to use two independent devices to complete the oil injection work in the up and down directions, thereby significantly improving the production efficiency and reducing the production cost. Moreover, the overall structure of the device is compact, and all functional components are integrated in the working box, which effectively reduces the occupied space. This is not only conducive to the space optimization of the production workshop, but also convenient for the movement and installation of the equipment, and reduces the requirements for the production environment. In addition, by arranging the oil injection system on the first drive unit 21, a high degree of integration of the mechanism is achieved. This design avoids the complexity of the oil circuit during the movement process, thereby reducing the risk of oil leakage and improving the stability and reliability of the equipment. At the same time, the equipment uses the first drive unit 21 to drive the oil injection system to move along the X-axis and Y-axis directions of the space, combined with the up and down movement of the second drive unit 22 (linear electric push rod), to achieve precise control and flexible adjustment of the oil injection position of the atomizer. This multi-axis drive design enables the equipment to clamp and inject oil to multiple groups of atomizers at one time, further improving production efficiency.

[0024] Furthermore, a first plate body 1 is provided on the top of the working box body, and the first atomizer oil filling fixture 4 is detachably mounted on the first plate body 1 through a first limiting mechanism, and a void avoidance groove 14 aligned with the first oil filling hole 412 is provided on the bottom surface of the first plate body 1; wherein the first limiting mechanism includes a first limiting plate 11 located on the left and right sides of the void avoidance groove 14, a second limiting plate 12 located on the rear side of the void avoidance groove 14, and a third limiting assembly 13 located on the left and right sides of the void avoidance groove 14, and the third limiting assembly 13 is provided with a fixed column 131, a pressure plate 132 and a handle 133, wherein the fixed column 131 is mounted on the left and right sides of the void avoidance groove 14, and the pressure plate 132 is sleeved on the fixed columns 131 on both sides and maintained in a relative position on the fixed columns 131 through the handle 133.

[0025] The above scheme has the beneficial effect that the first atomizer oil filling jig 4 is detachably mounted on the first plate body 1 through the first limiting mechanism, and this design makes the installation and removal of the jig very convenient. The operator only needs to simply operate the handle 133 to easily fix the jig on the first plate body 1 or remove it from the first plate body 1, thereby improving work efficiency.

[0026] In addition, the first limiting mechanism includes a first limiting plate 11 located on the left and right sides of the air avoidance groove 14, a second limiting plate 12 on the rear side, and a third limiting assembly 13 on the left and right sides. These limiting structures together ensure the accuracy of the first atomizer oil filling fixture 4 during installation. The setting of the air avoidance groove 14 is aligned with the first oil filling hole 412, which further ensures that the oil filling needle can accurately pass through the oil filling hole for oil filling operation, thereby improving the accuracy and stability of oil filling. Moreover, the design of the fixed column 131, the pressure plate 132 and the handle 133 in the third limiting assembly 13 enables the fixture to maintain a stable state after installation. The pressure plate 132 is mounted on the fixed column 131 and maintained in a relative position by the handle 133. This structure not only enhances the stability of the fixture, but also avoids safety problems caused by the shaking of the fixture during the oil filling process.

[0027] At the same time, since the first atomizer oil filling jig 4 is detachable, when the jig fails or needs maintenance, the operator can easily remove it for replacement or repair. This design improves the adaptability and maintainability of the equipment and extends the service life of the equipment. The design that is easy to disassemble and install allows the operator to quickly replace jigs of different models to meet the oil filling requirements of atomizers of different specifications. This flexibility optimizes the workflow, reduces the time required to replace jigs, and thus improves overall production efficiency.

[0028] Furthermore, the first atomizer oiling jig 4 includes a lower jig 41 and an upper jig 42, and both the lower jig 41 and the upper jig 42 are provided with a positioning groove 411 for positioning the incoming atomizer 43, and the lower jig 41 is provided with a plurality of positioning columns 414, and the upper jig 42 is provided with positioning holes 422 corresponding to the positioning columns 414, wherein the lower jig 41 is assembled with the upper jig 42 by inserting the positioning columns 414 into the corresponding positioning holes 422.

[0029] The beneficial effect is that the positioning column 414 provided on the lower fixture 41 and the corresponding positioning hole 422 on the upper fixture 42 provide reliable guarantee for the precise assembly of the two. The cooperation of the positioning column 414 and the positioning hole 422 can ensure that the lower fixture 41 and the upper fixture 42 achieve a high degree of consistency during assembly, thereby ensuring the accurate positioning of the atomizer during the oil filling process, and improving the accuracy and stability of the oil filling. The assembly method using the positioning column 414 and the positioning hole 422 makes the disassembly and assembly process of the lower fixture 41 and the upper fixture 42 simple and quick. The operator can easily realize the assembly and disassembly of the two without complicated tools or cumbersome steps, which greatly improves the maintenance efficiency of the equipment and reduces the maintenance cost.

[0030] Furthermore, the lower fixture 41 is provided with a first oil filling hole 412 corresponding to the atomizer oil filling port 431 one by one, and a guide member 413 is embedded in the first oil filling hole 412, and the guide member 413 is a tapered hole structure.

[0031] The beneficial effect is that the guide member 413 of the tapered hole structure is precisely embedded in the first oil filling hole 412, and its main design purpose is to provide a clear and stable guide for the injection needle during the oil filling process. Due to the structural characteristics of the tapered hole, it can ensure that the injection needle can be accurately aligned with the oil filling port 431 of the atomizer when inserted, thereby greatly improving the accuracy of oil filling.

[0032] Furthermore, a second plate 51 is provided inside the working box, and the second atomizer oil filling fixture 5 is detachably mounted on the second plate 51 through a second limiting mechanism, wherein the second limiting mechanism comprises a third limiting plate 52 fixed to the left and right sides of the surface of the second plate 51, and a fourth limiting plate 53 fixed to the rear side of the surface of the second plate 51. The structure of the second atomizer oil filling fixture 5 is basically similar to that of the first atomizer oil filling fixture 4, that is, it can be understood that the first atomizer oil filling fixture 4 is inverted 180°, and then the first oil filling hole 412 is facing upward, so as to constitute the second atomizer oil filling fixture 5, and the first oil filling hole 412 facing upward at the same time constitutes the second oil filling hole. Therefore, the specific structure of the second oil filling fixture will not be discussed in detail.

[0033] The beneficial effect is that the third limiting plate 52 and the fourth limiting plate 53 together form a frame, which provides a stable and reliable limiting space for the second atomizer oil filling fixture 5. When the fixture is placed in the frame, it can be firmly fixed, thereby avoiding inaccurate oil filling or safety problems caused by the movement or shaking of the fixture during the oil filling process.

[0034] The beneficial effect is that the second atomizer oil filling jig 5 is detachably mounted on the second plate 51 through the second limiting mechanism. This design makes the installation and removal of the jig very simple. The operator only needs to simply put the jig into or take it out of the frame without using complicated tools or performing cumbersome operations. This not only improves work efficiency, but also reduces maintenance costs. Since the jig is stably limited in the frame, it can maintain a constant relative position with the injection needle. This helps to ensure that the injection needle can be accurately inserted into the oil filling port 431 of the atomizer, thereby improving the accuracy and stability of oil filling.

[0035] Furthermore, the oil supply module 31 includes a stainless steel pressure barrel 311, the bottom of the stainless steel pressure barrel 311 is flat and the inside is conical and is provided with an oil supply port 312 connected to an oil supply pipeline 313, a replaceable stainless steel filter 3111 is provided inside the stainless steel pressure barrel 311, and the smoke oil is filtered out of internal impurities through the stainless steel filter 3111, an air intake manual sliding valve 315, a pressure relief safety valve 316 and a first thermocouple 317 are provided on the sealing cover 314 of the stainless steel pressure barrel 311, and the smoke oil is transported from the stainless steel pressure barrel 311 to the oil supply pipeline 313 through 0.2 MPa compressed gas (ordinary air or nitrogen), a low liquid level detection sensor 319 is provided at the bottom of the stainless steel pressure barrel 311 for monitoring the amount of smoke oil inside the pressure barrel, a first heating device 318318 is provided in the circumferential direction of the stainless steel pressure barrel 311, and a second heating device 3110 is provided in the circumferential direction of the oil supply pipeline 313.

[0036] The beneficial effects are as follows: the design of the stainless steel pressure barrel 311, especially its flat bottom and conical internal structure, is conducive to the efficient storage and discharge of the smoke oil. The conical internal structure can ensure that the smoke oil flows smoothly to the oil supply port 312 under the action of gravity, reducing residue and accumulation. At the same time, the replaceable stainless steel filter 3111 can effectively filter impurities in the smoke oil, ensure the cleanliness of the oil supply pipeline 313 and the quality of the smoke oil, thereby improving the stability and accuracy of oil injection. The air intake hand sliding valve 315 and the pressure relief safety valve 316 provided on the sealing cover 314 provide a safe and reliable pressure control mechanism for the stainless steel pressure barrel 311. The air intake hand sliding valve 315 can manually adjust the pressure in the barrel to meet different oil supply requirements; and the pressure relief safety valve 316 can automatically release the pressure when the pressure is too high, preventing safety accidents caused by excessive pressure, and ensuring the safety and stability of the oil supply process.

[0037] The low liquid level detection sensor 319 arranged at the bottom of the stainless steel pressure barrel 311 can monitor the liquid level of the tobacco oil in the barrel in real time. When the liquid level is too low, the sensor will send a signal for early warning, reminding the operator to replenish the tobacco oil in time, avoiding oil supply interruption or equipment damage caused by too low liquid level, and ensuring the continuity and stability of the oil filling process. The heating devices respectively arranged in the circumferential direction of the stainless steel pressure barrel 311 and the oil supply pipeline 313 can heat the tobacco oil as needed to improve its fluidity. Especially in low temperature environments, the heating device can ensure that the tobacco oil maintains an appropriate temperature, avoiding problems such as poor oil supply or blockage caused by too low temperature, thereby ensuring the oil filling efficiency and normal operation of the equipment.

[0038] Furthermore, the oil injection module 32 is provided with a plurality of groups of ceramic plunger pumps 321 (two groups are provided in the present embodiment), and an oil inlet 322 and an oil outlet 323 are provided on the ceramic plunger pump 321, the oil inlet 322 is connected to the oil supply pipe 313, and the oil outlet 323 is provided with a connector 325, and the connector 325 is respectively connected to the upward injection needle 324 and the downward injection needle 320 through the injection needle fixing cover 326, and a plurality of L-shaped air grooves are arranged circumferentially on the connector 325, and a sealing ring 329 is movably installed on the connector 325, and an annular air groove is provided on the sealing ring 329 to be connected to the L-shaped air groove, and an air intake quick connector 3342 is provided on the sealing ring 329 to be connected to the annular air groove, and a detachable oil receiving cup 328 is also provided on the connector 325. The heated compressed air output by the hot air module 33 enters through the air inlet quick connector 3342, passes through the connector 325, and then passes through the injection needle fixing cover 326 to converge to the injection needle surface for heating the upward injection needle 324 or the downward injection needle 320. Figure 7 , specifically a schematic diagram of the state after being equipped with an upward injection needle 324. During actual operation, the corresponding connector 325 can be extended and then fixed in a specified position, so that more accurate oil injection can be achieved.

[0039] The beneficial effect is that the oil injection module 32 is provided with multiple groups of ceramic plunger pumps 321, each group of pumps has an independent oil inlet 322 and an oil outlet 323. Such a design can realize multi-channel simultaneous oil injection, which significantly improves the oil injection efficiency. The ceramic plunger pump 321 is suitable for conveying various oil media due to its wear-resistant and corrosion-resistant characteristics, ensuring the stability and accuracy of the oil injection process. In this specific embodiment, two ceramic plunger pumps 321 are provided, and the oil outlet 323 of one ceramic plunger pump 321 is supplied with oil for two upward injection needles 324, and the oil outlet 323 of the other ceramic plunger pump 321 is supplied with oil for two downward injection needles 320.

[0040] The connector 325 is provided with a plurality of L-shaped air grooves arranged along the circumferential direction, and these air grooves are connected to the annular air grooves on the sealing ring 329 movably mounted on the connector 325. The sealing ring 329 is further provided with an air intake quick connector 3342 for receiving the heated compressed air output by the hot air module 33. This design not only ensures the sealing of the connector 325 and prevents oil leakage, but also heats the injection needle by heating the compressed air, thereby avoiding the viscosity or solidification of the oil due to too low temperature during the oil injection process, and improving the smoothness and accuracy of the oil injection. The heated compressed air output by the hot air module 33 enters the connector 325 through the air intake quick connector 3342, and then aggregates to the surface of the injection needle through the injection needle fixing cover 326. This heating method can quickly and evenly increase the temperature of the injection needle, ensure that the oil maintains appropriate fluidity during the oil injection process, and further improve the efficiency and quality of the oil injection.

[0041] See also Figure 4 Further, the hot air module 33 includes a copper rod 331, and a heater 332 and a second thermocouple 333 are respectively provided at both ends of the copper rod 331. A spiral copper tube 334 is wound around the copper rod 331, and the copper tube 334 is fixed by a heat-insulating fixture 336. An air intake pipe 3341 and an air supply pipe 3346 are provided on the copper tube 334. The air intake pipe 3341 is connected with a quick connector 3342, a PTFE pipe 3343, a speed regulating valve 3344 and a PU pipe 3345 in sequence. The air supply pipe 3346 is connected with the air intake quick connector 3342, and a heat-insulating pipe 3347 is provided on the air supply pipe 3346. The compressed air enters from the PU pipe 3345 and passes through the copper tube 334 to be heated to the required temperature, providing a hot air source for heating the injection needle.

[0042] The beneficial effect is that the copper rod 331 in the hot air module 33 is used as a heating element, and the two end surfaces thereof are respectively provided with a heater 332 and a second thermocouple 333. The heater 332 can quickly heat the copper rod 331, and the second thermocouple can detect the temperature of the copper rod 331 in real time, and feed back the signal to the control system to achieve precise temperature control. This design ensures the high efficiency and stability of the heating process, and avoids the oil injection problem caused by too high or too low temperature. A spiral copper tube 334 is wound around the copper rod 331. This design increases the contact area between the copper tube 334 and the copper rod 331, and improves the heat transfer efficiency. At the same time, the spiral design also allows the copper tube 334 to be heated evenly during the heating process, avoiding local overheating or non-heating, thereby ensuring the uniformity and stability of heating. The copper tube 334 is covered with an insulation tube 3347. This design can effectively reduce heat loss and improve heating efficiency. At the same time, the insulation tube 3347 can also protect the surrounding environment and operators from the influence of high temperature, ensuring the safety and comfort of work. In addition, the outer jacket of the air supply pipe 3346 is also provided with an insulating pipe 3347, which further reduces the loss of heat during the transmission process. The air intake pipe 3341 is connected with a quick connector 3342, a PTFE pipe 3343, a speed regulating valve 3344 and a PU pipe 3345 in sequence. This design makes the air circuit connection flexible and easy to maintain. The quick connector 3342 facilitates the quick connection and disconnection of the air circuit. The PTFE pipe 3343 and the PU pipe 3345 have good high temperature resistance and corrosion resistance. The speed regulating valve 3344 can adjust the flow and pressure of the gas to meet the needs of different oil injection scenarios. The air supply pipe 3346 is connected to the air intake quick connector 3342 to ensure a stable supply of heated compressed air. Through the air intake quick connector 3342, the heated compressed air can quickly enter the connector 325 and the injection needle to heat the injection needle. This design improves the fluidity of the oil during the oil injection process and avoids the oil injection problem caused by the viscosity or solidification of the oil.

[0043] See also Figure 8, further, the ceramic plunger pump 321 includes a fixed sleeve 62, in which a pumping cavity 621 and a movable cavity 671 are arranged, and an oil inlet 322 and an oil outlet 323 connected to the movable cavity 671 are arranged on the surface of the fixed sleeve 62, and the movable cavity 671 is connected to the pumping cavity 621 through the pumping oil port 674; a rotating rod 68, wherein the rotating rod 68 is movably mounted in the movable cavity 671, and an oil injection channel 681 penetrating the rotating rod 68 is arranged on the rotating rod 68; a first pumping device 66, wherein the output end of the first pumping device 66 is connected to the pumping cavity 621; a second driving part 22, wherein the second driving part 22 drives the rotating rod 68 to rotate; a second The driving unit 22 drives the rotating rod 68 to rotate so that one end opening of the oil injection channel 681 is connected to the oil inlet 322, and the other end opening of the oil injection channel 681 is connected to the oil extraction and discharge port 674. At the same time, the first extraction and discharge device 66 is started and the extraction and discharge chamber 621 generates a negative pressure and sucks the smoke oil from the oil inlet 322 into the oil injection channel 681; the second driving unit 22 drives the ceramic rotating rod 68 to rotate so that one end opening of the oil injection channel 681 is connected to the oil outlet 323, and the other end opening of the oil injection channel 681 is connected to the oil extraction and discharge port 674. The first extraction and discharge device 66 is started and the extraction and discharge chamber 621 generates a positive pressure and discharges the smoke oil from the oil injection channel 681 to the oil outlet 323.

[0044] In this embodiment, the beneficial effect is that during the process of extracting and discharging oil, the oil does not directly enter the extraction chamber 621, but is transferred through the oil injection channel 681 of the rotating rod 68. Such a design prevents the oil from flowing directly through the extraction chamber 621, thereby reducing the accumulation of oil in the extraction chamber 621. When the device needs to be cleaned, since the oil mainly remains in the oil inlet 322, the oil outlet 323, and the oil injection channel 681, these areas can be cleaned more easily and thoroughly, avoiding the problem of cross-flavor between different flavors of oil, and improving the hygiene of the device. At the same time, by controlling the movement of the rotating rod 68 and the working state of the first extraction device 66, the connection state of the oil injection channel 681 with the oil inlet 322, the oil outlet 323 and the extraction and discharge port 674 can be quickly changed. This dynamic connection mechanism enables the bubbles in the cavity to be effectively discharged as the oil flows, thereby avoiding the influence of bubbles on the precision of quantitative supply. This improvement significantly improves the injection accuracy and ensures that each oil injection can meet the preset standard. The entire oil filling process is precisely controlled by the second driving unit 22, which drives the ceramic rotating rod 68 to rotate to achieve the change of the connection state of the oil filling channel 681. When the smoke oil needs to be inhaled, one end of the oil filling channel 681 is connected to the oil inlet 322, and the other end is connected to the oil extraction and discharge port 674, and the first extraction and discharge device 66 generates negative pressure to inhale the smoke oil; when the smoke oil needs to be discharged, the two ends of the oil filling channel 681 are respectively connected to the oil outlet 323 and the oil extraction and discharge port 674, and the first extraction and discharge device 66 generates positive pressure to push the smoke oil out. This process design is concise and clear, easy to operate and efficient.

[0045] Furthermore, the fixed sleeve 62 is also provided with a fixed cavity 622, which is arranged perpendicular to the pumping cavity 621 and communicated with the pumping cavity 621, wherein the fixed cavity 622 is detachably equipped with a hollow special-shaped sleeve 67, and the hollow special-shaped sleeve 67 is provided with a second oil inlet 672 communicated with the oil inlet 322 and a second oil outlet 323673 communicated with the oil outlet 323, the interior of the hollow special-shaped sleeve 67 constitutes a movable cavity 671, and the oil pumping port 674 is arranged on the hollow special-shaped sleeve 67.

[0046] Beneficial effects: The fixed cavity 622 is detachably equipped with a hollow shaped sleeve 67, and this design makes the replacement and maintenance of the hollow shaped sleeve 67 more convenient. When the hollow shaped sleeve 67 is worn out due to long-term use or needs to be cleaned, it can be easily removed from the fixed cavity 622 for necessary repairs or replacements, thereby extending the service life of the oil injection pump. The hollow shaped sleeve 67 is made of ceramic, and this choice has multiple advantages. Ceramic materials have good corrosion resistance and wear resistance, can resist the chemical components and mechanical wear in the smoke oil, and extend the service life of the hollow shaped sleeve 67. Secondly, ceramic materials have good thermal stability and are not easily deformed or cracked due to temperature changes. The high surface smoothness of ceramic materials helps to reduce the resistance of the smoke oil during the flow process and improve the accuracy of oil injection.

[0047] Furthermore, the second oil inlet 672, the second oil outlet 673, and the oil extraction and discharge port 674 on the hollow special-shaped sleeve 67 are evenly distributed at 120° along the central axis of the hollow special-shaped sleeve. Moreover, the second oil inlet 672, the second oil outlet 673, and the oil extraction and discharge port 674 on the hollow special-shaped sleeve 67 are evenly distributed at 120° along the central axis of the hollow special-shaped sleeve. Such a layout helps to optimize the flow path of the smoke oil, reduce fluid resistance, and improve the oil filling efficiency. At the same time, this design also makes the smoke oil more uniform during the flow process, which helps to reduce the generation and accumulation of bubbles. At the same time, the hollow special-shaped sleeve 67 is made of ceramic.

[0048] Furthermore, the openings at both ends of the oil injection channel 681 are distributed at an angle of 120° along the axis of the rotating rod 68 , and one end of the rotating rod 68 extends out of the fixing sleeve 62 and is connected to the second oil injection driving part 69 .

[0049] Beneficial effects: The openings at both ends of the oil injection channel 681 on the rotating rod 68 are distributed at an angle of 120° along the axis of the rotating rod 68. This layout design enables the oil injection channel 681 to be flexibly connected or disconnected with the oil inlet, the oil outlet and the oil extraction and discharge port 674 during the rotation process. By accurately controlling the rotation angle of the rotating rod 68, it can be ensured that the smoke oil can smoothly enter or leave the oil injection channel 681 when needed, thereby achieving precise oil injection operation. One end of the rotating rod 68 extends out of the fixed sleeve 62 and is connected to the second oil injection drive unit 69. This design enables the second oil injection drive unit 69 to directly drive the rotating rod 68 to rotate without going through a complex transmission mechanism. This not only simplifies the structure of the oil injection pump, but also improves the simplicity and reliability of operation. At the same time, since the connection between the rotating rod 68 and the second oil injection drive unit 69 is firm, it can be ensured that no loosening or falling off occurs during the rotation process. By accurately controlling the rotation speed and rotation angle of the rotating rod 68, precise control of the oil injection process can be achieved. When the smoke oil needs to be inhaled, the rotating rod 68 rotates to make one end of the oil injection channel 681 connected to the oil inlet and the other end connected to the oil extraction and discharge port 674. At this time, the first extraction and discharge device 66 generates negative pressure to suck the smoke oil into the oil injection channel 681; when the smoke oil needs to be discharged, the rotating rod 68 rotates again to make one end of the oil injection channel 681 connected to the oil outlet and the other end connected to the oil extraction and discharge port 674. At this time, the first extraction and discharge device 66 generates positive pressure to push the smoke oil out of the oil injection channel 681 to the oil outlet. This efficient operation method not only improves the efficiency of oil injection, but also ensures the accuracy and stability of oil injection.

[0050] At the same time, the rotating rod 68 is made of ceramic material, which has the following beneficial effects: the ceramic material has excellent corrosion resistance and can resist the erosion of chemical components that may exist in the smoke oil. This means that the ceramic rotating rod 68 is not easily corroded by the smoke oil during long-term use, thereby maintaining the stability of its shape and performance, and extending the service life of the oil filling pump. The ceramic material has high hardness and good wear resistance, which enables the ceramic rotating rod 68 to resist friction and wear with other components during rotation. Even in the case of high-speed rotation and frequent operation, the ceramic rotating rod 68 can maintain a good surface finish and precision, ensuring the smoothness of the oil filling channel 681 and the stability of the oil filling precision.

[0051] Furthermore, a ceramic sleeve 64 is installed in the pumping chamber 621 , and the first pumping device 66 includes a screw motor 661 that moves in the horizontal direction. A ceramic piston rod 65 is installed at the output end of the screw motor 661 , and the screw motor 661 drives the ceramic piston rod 65 to move back and forth in the ceramic sleeve 64 .

[0052] Beneficial effects: Both the ceramic sleeve 64 and the ceramic piston rod 65 are made of ceramic material, which makes them have excellent corrosion resistance. When handling chemical liquids such as smoke oil, they can effectively resist corrosion and extend the service life of the equipment. The ceramic material has high hardness and good wear resistance, and the friction and wear between the ceramic sleeve 64 and the ceramic piston rod 65 are small. This means that during long-term use, the gap between the two changes little, ensuring the stability and reliability of the extraction process. The high smoothness of the ceramic material makes the fit between the ceramic sleeve 64 and the ceramic piston rod 65 tighter, which helps to improve the sealing performance. This helps prevent the leakage of smoke oil during the extraction process and ensures the accuracy and cleanliness of the oil injection. The screw motor 661 drives the ceramic piston rod 65 to move back and forth in the ceramic sleeve 64. This linear motion is stable and reliable. By accurately controlling the movement speed and stroke of the screw motor 661, accurate control of the extraction process can be achieved, and the accuracy and stability of the oil injection can be improved. Due to the hardness and smoothness of the ceramic material, the friction sound generated when the ceramic piston rod 65 moves in the ceramic sleeve 64 is relatively small, which helps to reduce the working noise of the oil injection pump and provide a more comfortable use environment.

[0053] Furthermore, it also includes a fixed bracket assembly, which includes a fixed base plate 61 and a fixed panel 63. The fixed panel 63 is installed on the surface of the fixed base plate 61, and the surface of the fixed panel 63 is provided with a first limiting groove 631 for fitting the fixed sleeve 62.

[0054] Beneficial effects: The fixed base plate 61 serves as the basis of the entire fixed bracket assembly and provides a stable support surface. The fixed panel 63 is installed on the surface of the fixed base plate 61 and is firmly combined with the fixed base plate 61 through a specific structural design (such as bolt connection, welding, etc.). This stable base design ensures that the oil injection pump will not be displaced or tilted due to vibration or external force during operation. The surface of the fixed panel 63 is provided with a first limiting groove 631 for fitting the fixed sleeve 62. This design enables the fixed sleeve 62 to be accurately aligned and fixed in a predetermined position during installation, avoiding performance degradation or failure caused by installation position deviation. The precise size and shape of the first limiting groove 631 ensure the close fit between the fixed sleeve 62 and the fixed panel 63, further improving the overall accuracy and stability of the equipment. The design of the fixed bracket assembly takes into account the convenience of installation and maintenance. Through standardized interfaces and connection methods, users can easily complete the installation and removal of the fixed sleeve 62. In addition, the structure of the fixed bracket assembly is relatively simple and clear, which helps users to quickly locate problems and take corresponding solutions when performing equipment maintenance.

[0055] Furthermore, the first pumping device 66 also includes a limiting device and a screw motor fixing plate 662, wherein the limiting device includes a U-shaped limiting bracket 663, a piston rod connecting piece 665, and a fixed clamping ring 666, wherein the screw motor is fixed to the surface of the fixed base plate 61 through the screw motor fixing plate 662, wherein the output end of the screw motor passes through the limiting bracket 663 and is equipped with a piston rod connecting piece 665, and the movable rod connecting piece is connected to the ceramic piston rod 65 through the fixed clamping ring 666, and a second limiting groove 611 is provided on the surface of the fixed base plate 61, and a limiting linear guide rail 664 is installed on the second limiting groove 611, and the limiting bracket 663 is movably equipped on the limiting linear guide rail 664 through a slider 667.

[0056] Beneficial effects: The U-shaped limit bracket 663 provides a stable support and guide frame for the piston rod and its connecting parts, preventing the ceramic piston rod 65 from deflecting or shaking during the linear motion. The rigidity and stability of the overall structure are enhanced, and the linearity and accuracy of the movement of the ceramic piston rod 65 are ensured.

[0057] The piston rod connector 665 is responsible for connecting the output end of the screw motor with the ceramic piston rod 65 to ensure effective transmission between the two. Through precise design and manufacturing, the piston rod connector 665 can achieve efficient and reliable transmission, reducing energy loss and mechanical wear. The fixed clamping ring 666 firmly connects the piston rod connector 665 and the ceramic piston rod 65 to prevent relative movement or looseness between the two.

[0058] Moreover, the second limiting groove 611 provided on the fixed base plate 61 is equipped with a limiting linear guide rail 664, and the limiting bracket 663 is movably mounted on the guide rail through a slider 667. This design limits the movement trajectory of the limiting bracket 663 and ensures its precise movement in a specific direction. The movement accuracy and stability of the limiting bracket 663 are improved, and the performance degradation or failure caused by movement deviation is reduced. At the same time, it also provides convenience for subsequent maintenance and adjustment. Working process: When the screw motor is working, its output end drives the ceramic piston rod 65 to move back and forth in the ceramic sleeve 64 through the piston rod connector 665. In this process, the U-shaped limiting bracket 663 and the limiting linear guide rail 664 work together to ensure the stability and linearity of the movement of the ceramic piston rod 65. The fixed clamping ring 666 provides a reliable connection and locking force to prevent the connector from loosening or falling off.

[0059] Furthermore, the second oil injection driving unit 69 includes a stepper motor 691 , the output end of the stepper motor 691 is connected to the first bevel gear 693 , and one end of the rotating rod 68 extending out of the fixing sleeve 62 is equipped with a second bevel gear 694 meshing with the first bevel gear 693 .

[0060] The output end of the stepper motor 691 is connected to the first bevel gear 693, forming the starting point of the transmission system. The first bevel gear 693 is meshed with the second bevel gear 694 to achieve power conversion and transmission. The characteristics of bevel gear transmission are that it can realize power transmission between different axes and has high transmission efficiency and load-bearing capacity. In the oil injection pump, this transmission method can effectively convert the rotational motion of the motor into the rotational motion of the rotating rod 68. One end of the rotating rod 68 extends out of the fixed sleeve 62 and is connected to the second bevel gear 694. This connection method ensures that the rotating rod 68 can rotate synchronously with the rotation of the second bevel gear 694. By adjusting the module and gear ratio of the bevel gear, the speed and direction of the rotating rod 68 can be accurately controlled, thereby meeting the requirements of the oil injection pump for oil injection accuracy and efficiency. The design of the second oil injection drive unit 69 takes into account the compactness of the structure. By compactly integrating components such as the motor, bevel gear and rotating rod 68, the floor space and weight of the equipment are reduced, making the oil injection pump easier to install and transport.

[0061] Furthermore, the second oil injection driving unit 69 further includes a motor fixing plate 692 , and the stepping motor 691 is fixed on the fixing plate through the motor fixing plate 692 .

[0062] Beneficial effects: The main function of the motor fixing plate 692 is to firmly fix the stepper motor 691 on the fixing plate. Through reasonable structural design and appropriate fixing force, the motor fixing plate 692 can effectively prevent the vibration and loosening of the motor during operation, thereby ensuring the stable rotation of the rotating rod 68 and the accurate oil injection of the oil injection pump. The design of the motor fixing plate 692 also takes into account the convenience of maintenance. Through the reserved maintenance interface or easily removable connectors, the user can easily repair or replace the motor. This design reduces the complexity and time cost of maintenance work and improves the overall availability and reliability of the equipment.
