Description

Technical Field

[0001] This utility model relates to the field of atomizing bullet technology, and in particular to an atomizing bullet with a detachable atomizing core assembly. Background Technology

[0002] Atomization is the process of physically transforming a liquid into extremely small particles suspended in the air. The core of this technology lies in overcoming the surface tension of the liquid, dispersing it into fine particles typically on the micrometer scale. From a physics perspective, atomization requires external energy input, commonly including mechanical energy, thermal energy, and sound energy. This energy acts on the liquid, causing it to form droplets.

[0003] The application fields of atomization technology are very wide, including medical inhalation therapy, humidifiers, spraying, aromatherapy, agricultural spraying and other scenarios.

[0004] Based on their different working principles, atomization technology is mainly divided into two categories: traditional atomization and ultrasonic atomization. Traditional atomization mainly relies on mechanical or pneumatic action, such as a high-speed rotating impeller or needle forcibly dispersing the liquid (mechanical atomization), or using high-speed airflow to tear the liquid into fine particles (pneumatic atomization). Another traditional method is heating and evaporation, where the liquid is heated to produce steam, which is then cooled and condensed into small water droplets.

[0005] Existing atomizing devices mainly consist of an atomizing cartridge and a power supply assembly. Typically, an atomizing cartridge includes an atomizing cartridge shell, a liquid storage chamber located within the atomizing cartridge shell, and an atomizing core assembly.

[0006] The existing atomizing cartridges, once assembled with the atomizer core and reservoir, cannot be disassembled. Forcibly disassembling them can result in leakage or damage to the atomizer core. Furthermore, users cannot freely replace their preferred atomizer core, or remove and reuse the core when the reservoir is empty.

[0007] In addition, a typical atomizing core assembly includes a base and an atomizing core mounted on the base. A first electrode and a second electrode are disposed on the base. The atomizing core includes an air guide tube, an insulating ring, and an atomizing core. The air guide tube has a receiving cavity, with an outlet at its upper end communicating with the receiving cavity and an installation port at its lower end communicating with the receiving cavity. A liquid inlet and an air inlet are provided on the side of the air guide tube, both communicating with the receiving cavity. The air inlet is located below the liquid inlet. The air guide tube is made of conductive material, and the insulating ring is disposed in the installation port. The atomizing core is disposed within the receiving cavity and has an atomizing air passage communicating with the outlet and the air inlet. The atomizing core includes a liquid guiding element and an atomizing element disposed within the liquid guiding element. The liquid guiding element is located inside the liquid inlet and covers it. The atomizing element is connected to a first pin and a second pin. The first pin is connected to the air guide tube. The first electrode is welded to the air guide tube, and the second pin is welded to the second electrode.

[0008] However, since the electrodes and pins are soldered together, and the pins of the heating element are quite delicate, the soldering process is complex. In addition, it is easy to produce poor solder joints, which leads to unreliable connections and affects the normal use of the atomizing core assembly.

[0009] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

One end of the main air passage 43 is connected to the nozzle 41. In this embodiment, the suction nozzle 41 is disposed on the top of the housing 42. The suction nozzle 41 extends out of the housing 42 in the first position 41e and retracts into the housing 42 in the second position 41f.

[0025] The upper end face of the housing 42 is recessed to the bottom to provide a groove 421 for the suction nozzle 41 to move up and down. The suction nozzle 41 is installed in the groove 421. The inner side wall of the groove 421 is formed with a first limiting step 422 and the suction nozzle 41 is formed with a second limiting step 411. When the nozzle 41 is in the first position 41e, the second limiting step portion 411 abuts against the first limiting step portion 422.

[0026] The atomizing core assembly 30 includes a base 20 and an atomizing core unit 10 mounted on the base 20. The atomizing core unit 10 includes an air duct 11 and an atomizing core 13. The air duct 11 has a receiving cavity 111 inside, and the upper end of the air duct 11 has an air outlet 112 that communicates with the receiving cavity 111. The lower end of the air duct 11 has an installation port 116 that communicates with the receiving cavity 111.

[0027] A sealing cap 16 is interference-fitted to the air outlet 112 of the air guide tube 11. The sealing cap 16 has an open cavity 161 at the top and bottom. The outer circumference of the top of the sealing cap 16 extends horizontally outward to form an annular sealing edge 162. The top end of the air guide tube 11 abuts against the annular sealing edge 162, and the annular sealing edge 162 is interference-fitted with the main air passage 43. The annular sealing edge 162 prevents liquid in the liquid storage chamber 44 from entering the air guide tube 11 through the gap between the air guide tube 11 and the main air passage 43.

[0028] The side of the air inlet tube 11 is provided with a liquid inlet hole 113 and an air inlet hole 114. Both the liquid inlet hole 113 and the air inlet hole 114 are connected to the accommodating cavity 111, and the air inlet hole 114 is located below the liquid inlet hole 113.

[0029] The atomizing core 13 is disposed in the accommodating cavity 111. The atomizing core 13 has an atomizing air passage 133 that connects the air outlet 112 and the air inlet 114. The atomizing core 13 includes a liquid guiding element 131, an insulating ring 12, a conductive ring 14, a positioning element 15, and an atomizing element 132 disposed in the liquid guiding element 131. The liquid guiding element 131 is located inside the liquid inlet 113 and covers the liquid inlet 113. The insulating ring 12 is disposed in the mounting opening 116. In this embodiment, the insulating ring 12 is tightly fitted in the mounting opening 116. A second through hole 121 is provided on the insulating ring 12.

[0030] The atomizing element 132 is connected to a first pin 134 and a second pin 135. The air guide tube 11 is made of conductive material. The first pin 134 is connected to the air guide tube 11. In this embodiment, the first pin 134 is clamped between the outer wall of the insulating ring 12 and the inner wall of the air guide tube 11.

[0031] The conductive ring 14 is disposed on the insulating ring 12 and isolated from the air duct 11, and the second pin 135 is connected to the conductive ring 14; in this embodiment, the conductive ring 14 is installed in the second through hole 121, and the second pin 135 is clamped between the outer wall of the conductive ring 14 and the inner wall of the second through hole 121.

[0032] The base 20 is provided with a first electrode 21, a second electrode 22 and a positioning hole 23 for installing and positioning the atomizing core unit 10. The first electrode 21 has a claw 211 that extends into the positioning hole 23, and the second electrode 22 has an elastic contact portion 221 that extends into the positioning hole 23. When the atomizing core 13 is installed in the positioning hole 23, the claw 211 of the first electrode 21 contacts and is electrically connected to the outer surface of the air guide tube 11, and the elastic contact portion 221 of the second electrode 22 contacts and is electrically connected to the conductive ring 14.

[0033] The surface of the claw 211 that contacts the outer surface of the air duct 11 is provided with a plurality of elastic teeth 212 along the circumferential direction.

[0034] In another embodiment, such as Figure 19 As shown, the outer surface of the air duct 11 is provided with resistance patterns 117. For example, the resistance patterns 117 include laser-engraved horizontal lines, pineapple patterns, or other patterns that increase resistance. The claws 211 contact and are electrically connected to the resistance patterns 117. Thus, during the process of inserting the atomizing core unit 10 into the positioning hole 23 of the base 20, the elastic teeth 212 interfere with the resistance patterns 117 of the air duct 11, causing the elastic teeth 212 to deform and produce a barb-like structure, so that the atomizing core unit 10 can only be inserted and cannot be removed.

[0035] In this embodiment, the outer wall of the insulating ring 12 and / or the inner wall of the second through hole 121 are provided with a plurality of retaining grooves 122 along their circumference.

[0036] The side of the air guide tube 11 is also provided with a first through hole 115 that connects to the receiving cavity 111. In this embodiment, the top of the insulating ring 12 is higher than the first through hole 115, and part of the claws 211 of the first electrode 21 pass through the first through hole 115 and are adapted to the tooth grooves 122 on the outer wall of the insulating ring 12.

[0037] In this embodiment, when the air guide tube 11 is installed from top to bottom into the positioning hole 23, several elastic locking teeth 212 are deformed by the air guide tube 11. Some of the elastic locking teeth 212 pass through the first through hole 115 and enter the corresponding locking tooth groove 122. The elastic locking teeth 212 elastically clamp the air guide tube 11 so that the elastic locking teeth 212 can only be inserted and cannot be removed. Thus, the process is simple and the connection is reliable. Therefore, during the process of installing the atomizing core unit 10 into the positioning hole 23 of the base 20, some of the elastic locking teeth 212 pass through the first through hole 115 and are pressed against the air guide tube 11, causing the elastic locking teeth 212 to deform and produce a barb-like structure, so that the atomizing core unit 10 can only be inserted and cannot be removed.

[0038] In this embodiment, a third through hole 141 is provided on the conductive ring 14, and the third through hole 141 is connected to the second through hole 121; When the atomizing core unit 10 is installed in the positioning hole 23, the third through hole 141 connects to the positioning hole 23, and the elastic contact portion 221 of the second electrode 22 extends into the third through hole 141 through the second through hole 121 and contacts and is electrically connected to the inner wall of the conductive ring 14.

The first horizontal portion 215 bends from the upper end of the first vertical portion 214 toward the positioning hole 23 and extends horizontally. The claw 211 is formed on the end of the first horizontal portion 215 away from the first vertical portion 214.

The second substrate portion 222 is connected to the lower end face of the base 20. The second vertical portion 223 extends into the positioning hole 23 from bottom to top through the second through hole 25, and the upper end of the second vertical portion 223 is located above the second through hole 25. The elastic contact portion 221 is bent from the upper end of the second vertical portion 223 and extends horizontally away from the second vertical portion 223.

[0054] When the main air passage 43 is in the first position 41e, its other end is located in the through hole 451 and does not extend into the liquid storage cavity 44. When the main air passage 43 is in the second position 41f, its other end extends into the clearance hole 464 through the through hole 451 and the liquid storage cavity 44 in sequence and is press-fitted into the clearance hole 464.

[0055] The suction nozzle 41 can reciprocate vertically relative to the housing 42 via a push-pull, spiral, or spring mechanism. Figure 14 and Figure 15 As shown, the suction nozzle 41a can reciprocate vertically relative to the housing 42a via a spiral mechanism. Figure 16 and Figure 17 As shown, the suction nozzle 41b can reciprocate up and down relative to the housing 42b by pushing and pulling.

[0056] In this embodiment, as Figures 1 to 13 As shown, the suction nozzle 41 can reciprocate vertically relative to the housing 42 via a spring.

[0057] The housing 42 is provided with a suction hook positioning plate 481 fixedly installed inside the housing 42, a suction hook 482 connected to the suction nozzle 41 at one end, and an elastic reset member 483 for providing elastic force to the suction nozzle 41. The two ends of the elastic reset member 483 are respectively connected to the suction nozzle 41 and the suction hook positioning plate 481.

[0058] The suction nozzle hook positioning plate 481 has a groove 484 extending in the vertical direction. The groove 484 has a first moving position 485 and a second moving position 486. The other end of the suction nozzle hook 482 can move to the first moving position 485 and the second moving position 486 as the suction nozzle 41 moves. When the suction nozzle 4141 moves to the first position 41e, the other end of the suction nozzle hook 482 moves to the first moving position 485; when the suction nozzle 41 moves to the second position 41f, the other end of the suction nozzle hook 482 moves to the second moving position 486. At the same time, the elastic reset member 483 is compressed and deformed.

[0059] like Figure 13 As shown, the assembly process of this embodiment will be roughly described by taking the suction nozzle 4141 being able to reciprocate up and down relative to the housing 42 by means of a spring as an example (by default, when the suction nozzle 4141 is pressed down, the suction nozzle 4141 moves to the second position 41f, and the other end of the suction nozzle 41 hook 482 moves to the second moving position 486, at which time the elastic reset element 483 is compressed and deformed).

[0060] 1. Install the separator 46 from bottom to top in the inner cavity 423. The inner cavity 423 is divided into a liquid storage cavity 44 and an installation groove 45 by the separator 46. The main flue 43 extends into the clearance hole 4644. At this time, the liquid injection plug 463 can be opened, and the required liquid can be injected into the liquid storage cavity 44 through the liquid injection hole 462. 2. First, install the atomizing core unit 10 onto the base 20 to form the atomizing core assembly 30; 3. Install the base 20 from bottom to top into the mounting groove 45 of the base 20, and extend the air guide pipe 11 into the main flue 43 through the clearance hole 464 to isolate the mounting groove 45 from the liquid storage chamber 44. When the suction nozzle 41 is needed, press the suction nozzle 41 down again. Under the reset force of the elastic reset element 483, the suction nozzle 41 moves from the second position 41f to the first position 41e and extends out of the housing 42. The other end of the suction nozzle 41 hook 482 moves from the second moving position 486 to the first moving position 485. At the same time, the main flue 43 opens the liquid inlet hole 113 at the first position 41e so that the liquid in the liquid storage chamber 44 enters the liquid guiding element 131131 through the liquid inlet hole 113.

[0061] Next, if it is necessary to disassemble the atomizing core assembly 30, simply press down on the mouthpiece 41. The mouthpiece 41 moves from the first position 41e to the second position 41f. The other end of the mouthpiece 41 hook 482 moves from the first position 41e to the second moving position 486. At this time, the elastic reset element is compressed and deformed. When the main body flue 43 is in the second position 41f, it blocks the liquid inlet hole 113 and its other end extends into the clearance hole 464 to prevent the liquid in the liquid storage chamber 44 from entering the liquid guiding element 131 through the liquid inlet hole 113. At this time, the atomizing core assembly 30 can be disassembled.

[0062] The key design feature of this utility model is: 1. The mouthpiece moves the main airway to close the liquid inlet, thereby allowing the atomizer core assembly to be disassembled. This makes it easy for users to replace their preferred atomizer core or solves the problem of not being able to remove the atomizer core for reuse when the liquid in the reservoir is used up, greatly improving the convenience and flexibility of use. 2. Through the detachable structure design of the separator, on the one hand, different volumes of liquid storage chambers can be achieved by replacing separators of different sizes; on the other hand, after the separator is disassembled, it is convenient to clean the liquid storage chamber. 3. Through the claws of the first electrode and the elastic contact part of the second electrode, after the atomizing core is installed in the positioning hole, the claws of the first electrode contact and are electrically connected to the outer surface of the air guide tube, and the elastic contact part of the second electrode contacts and is electrically connected to the conductive ring, which facilitates the assembly and positioning between the atomizing core and the base, and realizes the solderless electrical connection between the atomizing component and the first and second electrodes. Its structure is simple, the connection is reliable, the process is simple, and it is easy to produce. 4. The friction between the first electrode's claws and the air guide tube is greatly increased by the resistance grooves on the outer surface of the air guide tube and the locking teeth of the claws, ensuring the stability and reliability of the atomizing core after assembly. 5. The toothed grooves of the insulating ring increase the contact area between the first and second pins, ensuring their stability and reliability and preventing them from easily coming loose.

[0063] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
