Description

Technical Field

[0001] This utility model relates to the field of oil injection technology, and more specifically, it relates to an oil injection device with the atomizer facing downwards. Background Technology

[0002] Electronic atomizers are devices that atomize e-liquid using methods such as high temperature, high pressure, or ultrasound. During their automated production process, or after the e-liquid has been consumed, it is necessary to refill the electronic atomizer with e-liquid. Current electronic atomizers typically use automated refilling mechanisms. E-liquid from the supply tank is delivered to the refilling module via a supply pipe, and then injected into the atomizer through the injection needle of the refilling module.

[0003] Currently, a special type of e-liquid is popular abroad, especially in some European and American countries. This e-liquid is solid at room temperature, but requires heating and precise temperature control during filling to transform it into a high-viscosity liquid. On one hand, the atomizer structure limits the maximum diameter of the injection needle used during filling; on the other hand, the e-liquid cools as it passes through the needle during injection, and its high viscosity significantly increases the pressure during filling. Excessive speed can damage the filling module, necessitating a reduction in filling speed. Currently, efficient and stable filling cannot be achieved for this type of e-liquid. Furthermore, as the production of this type of e-liquid continues to increase, its price has dropped significantly, making cost reduction for filling an urgent priority. Existing atomizer filling equipment has limitations in addressing these issues, being incompatible with various e-liquids and inefficient, requiring frequent fixture adjustments.

By integrating all key components onto the mainboard and rationally arranging the modules, the operation process is simplified, reducing operational difficulty and complexity, and improving the automation level of the production line.

[0031] A device for injecting oil with the atomizer facing downwards, see [link / reference] Figures 1 to 5 ,include:

[0032] Welding frame body 1;

[0033] Mainboard 2, which is installed inside the welding frame body 1, is used to carry all mechanisms;

[0034] The oil injection system 3 includes an oil supply module 31, an oil injection module 32, and a heating module 33. The oil supply module 31 and the oil injection module 32 are both equipped with heating and temperature control functions. The oil injection module 32 is equipped with multiple sets of ceramic plunger pumps 321 and injection needles 324. The injection needles 324 correspond to the oil injection holes 423.

[0035] The atomizer filling fixture 4 is provided with multiple positioning slots 411 for accommodating the atomizer, and the top of the atomizer filling fixture 4 is provided with a filling hole 423 corresponding to the atomizer filling port 431.

[0036] The first drive unit 21 is located above the main board 2 and is connected to the oil injection system 3. The first drive unit 21 is a lead screw module that moves in the X and Y directions and is used to drive the injection needle 324 to correspond one by one with the oil injection hole 423.

[0037] The second drive unit 22 is disposed on the lower surface of the main board 2 and is detachably mounted with the atomizer filling fixture 4. The second drive unit 22 is used to drive the atomizer fixture 4 to move upward until the injection needle 324 completely pierces the sealing silicone of the atomizer and then fills in oil.

[0038] The advantages of the above solution are that setting the entire oil filling system 3 on the screw module facilitates the integrated design of the mechanism, avoids oil circuit movement, and thus reduces the risk of oil leakage; compared with the single-axis linear module, the X and Y dual-axis screw module can realize the oil filling of multiple atomizers in one clamping, thereby reducing labor intensity and improving oil filling efficiency.

[0039] Preferably, the limiting mechanism includes a first limiting plate 221 fixed to the left and right sides of the top of the second drive unit 22, and a second limiting plate 222 fixed to the rear side of the top of the second drive unit 22. Its advantage is that it is compatible with various atomizer filling systems.

[0040] In this example, the atomizer filling fixture includes a lower fixture 41 and an upper fixture 42. Both the lower fixture 41 and the upper fixture 42 are provided with positioning grooves 411 and 421 for positioning the incoming atomizer 43. The lower fixture 41 is provided with four positioning posts 414 that correspond to the positioning holes 422 on the upper fixture 42.

[0041] Its advantages are that the upper and lower slot positioning method can minimize the slot depth, thus facilitating atomizer installation, and can also expose the atomizer oil cup for easy observation of the oil filling status.

[0042] Specifically, the upper fixture 42 is provided with oil filling holes 423 that correspond one-to-one with the oil filling port 431 of the atomizer, and a guide member 424 is embedded in the oil filling hole 423. The guide member 424 has a conical hole structure.

[0043] Its beneficial effect is that adding a tapered hole guide structure to the oil injection hole 423 can eliminate the positional deviation caused by the installation differences of different injection needles 324 and the bending deformation of the injection needle 324, and can also reduce the transmission accuracy of the equipment, thereby reducing the equipment cost.

[0044] Furthermore, the first drive unit 21 is a lead screw module driven by a stepper motor, and the second drive unit 22 is an electric cylinder driven by a stepper motor. The advantages are that, due to the function of the aforementioned guide member 424, the alignment requirements between the injection needle 324 and the atomizer filling port 431 can be met without excessively high precision. The lead screw module further reduces costs and has a simple structure and is easy to maintain. Compared to a pneumatic cylinder, the electric cylinder is simpler to install, has higher reliability when driving such high loads, and is more convenient when adjusting the filling position.

[0045] In this example, the oil supply module 31 includes a stainless steel pressure tank 311. The bottom of the stainless steel pressure tank 311 is flat and the inside is conical, with an oil supply port 312 connected to the oil supply pipe 313. A replaceable stainless steel filter screen 3111 is provided inside the stainless steel pressure tank 311. The e-liquid passes through the filter screen 3111 to remove internal impurities. An air intake hand slide valve 315 and a pressure relief safety valve 316 are provided on the sealing cap 314 of the stainless steel pressure tank 311. The e-liquid is transported from the stainless steel pressure tank 311 to the oil supply pipe 313 through 0.2 MPa compressed air (ordinary gas or nitrogen). A low liquid level detection sensor 319 is provided at the bottom of the stainless steel pressure tank 311 to monitor the amount of e-liquid inside the pressure tank. A first heating device 318 is provided on the circumference of the stainless steel pressure tank 311 and the oil supply pipe 313, respectively.

[0046] Its beneficial effects are that the flat and conical bottom of the tank can maximize the emptying of e-liquid in the tank, and when adding e-liquid, air is less likely to enter the oil passage and affect the filling accuracy. The 0.2 MPa air pressure can make the e-liquid quickly fill the ceramic plunger pump 321, and the stainless steel filter screen removes impurities inside the e-liquid, thereby improving the filling efficiency and e-liquid quality.

[0047] In this example, the oil injection module 32 is a ceramic plunger pump 321. The ceramic plunger pump 321 is provided with an oil inlet 322 and an oil outlet 323. The oil inlet 322 is connected to the oil supply pipe 313, and the oil outlet 323 is connected to the oil injection needle valve 325 through the oil outlet pipe 326. The oil injection needle valve 325 is equipped with an injection needle 324 and an injection needle fixing cover 327, and the injection needle fixing cover 327 is wrapped around the lower outer side of the oil injection needle valve 325.

[0048] The oil injection module 32 is equipped with multiple ceramic plunger pumps 321 and oil injection needles. The ceramic plunger pumps 321 are provided with an oil inlet 322 and an oil outlet 323. The oil inlet 322 is connected to the oil supply pipe 313, and the oil outlet 323 is connected to the oil injection needle valve 325 through an oil outlet pipe 326. The oil injection needle valve 325 is equipped with an injection needle 324 and an injection needle fixing cover 327, and the injection needle fixing cover 327 is wrapped around the lower outer side of the oil injection needle valve 325.

[0049] Its beneficial effect is that multiple sets of ceramic plunger pumps 321 are set on the oil filling module 32 and arranged in parallel at a certain distance to simultaneously fill multiple atomizers with oil, thereby improving the oil filling efficiency.

[0050] Preferably, it also includes an oil injection device fixing plate 328, which is disposed above the first drive unit 21, and the ceramic plunger pump 321 is mounted on the oil injection device fixing plate 328.

[0051] The beneficial effect is that by fixing the oil injection device, such as the ceramic plunger pump 321, to the oil injection device mounting plate 328, and placing this mounting plate above the first drive unit 21, the entire oil injection system 3 can be made more compact and integrated. This design not only simplifies the internal structure of the equipment but also helps reduce maintenance difficulty and failure rate caused by the dispersion of components. The oil injection device mounting plate 328 provides a stable support platform for key components such as the ceramic plunger pump 321. During equipment operation, especially during high-speed movement in the X and Y directions, the mounting plate can effectively reduce component displacement caused by vibration or inertial forces, thereby ensuring the stability and accuracy of the oil injection process. When maintenance or replacement of the oil injection device, such as the ceramic plunger pump 321, is required, disassembly and installation can be made easier through the oil injection device mounting plate 328. This modular design improves the maintainability of the equipment and reduces maintenance costs and time.

[0052] Preferably, the heating module 33 includes a UVB heating lamp 331, the tail end of which is fixed on a UVB heating lamp fixing plate 332. The UVB heating lamp 331 generates heat energy by emitting light to provide a heat source for heating the injection needle 324.

[0053] Its beneficial effects include precise temperature control: the UVB heating lamp 331 generates heat through light emission, enabling precise temperature control of the injection needle 324 and its surrounding environment. This is particularly important for e-liquids that require specific temperature conditions for filling, such as solid e-liquids that transform into a high-viscosity liquid after heating, thus ensuring a smooth filling process. The UVB heating lamp 331 features rapid heating, reaching the required heating temperature in a short time, improving heating efficiency. This helps reduce waiting time, speeds up the production process, and thus improves overall production efficiency. The UVB heating lamp 331 provides relatively uniform heat distribution, offering a stable heat source for the injection needle 324 and avoiding filling problems caused by localized overheating or undercooling. This helps ensure consistent filling performance for every atomizer.

[0054] Furthermore, the UVB heating lamp 331, as a non-contact heating element, reduces the safety risks associated with direct contact. At the same time, the design of the heating lamp mounting plate ensures the stable installation of the heating element, preventing damage or accidents caused by vibration or misoperation.

[0055] The above embodiments are merely explanations of the present utility model and are not intended to limit the present utility model. Those skilled in the art can make modifications to the embodiments without contributing any inventive step after reading this specification, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.
