Description

Technical Field

[0001] The present invention belongs to the technical field of atomizing bullets, and in particular relates to an atomizing bullet and an atomizing device. Background Art

[0002] An electronic atomizer device consists of an atomizer cartridge and a power supply. The cartridge itself houses a liquid reservoir, an airflow channel, and an atomizer assembly. Existing atomizer cartridges typically have the liquid reservoir pre-filled with the solution to be atomized. Therefore, during production and shipment, the long transportation and high-altitude, low-pressure air transport can cause the liquid in the reservoir to leak into the atomizer assembly, leading to leakage.

[0003] Therefore, some products with isolation silicone kits have appeared on the market. By pre-installing the isolation silicone kit on the atomizer assembly, the atomizer assembly is isolated from the solution in the liquid reservoir. When the isolation silicone kit is pulled during use, the liquid path of the atomizer assembly is connected to the liquid reservoir. For details, please refer to the published Chinese patent: CN209995382U, an isolation silicone electronic cigarette with oil-cotton separation function.

[0004] However, existing silicone isolation kits on the market require a certain amount of sliding travel when pulled. Once the silicone isolation rod is broken, a portion of the atomizing air path is formed through the internal chamber of the isolation silicone kit. When the high-temperature air path generated by atomization within the atomizing assembly encounters the silicone atomizing air path, condensation is easily generated. This can cause the user to inhale the condensation into the mouth during subsequent puffs, causing discomfort. Summary of the Invention

[0005] The purpose of the embodiment of the present application is to provide an atomizing bomb, which aims to achieve sealed transportation by sealing the atomizing assembly through an isolation sleeve. After the control part of the isolation sealing sleeve is pulled off, the atomizing gas path does not need to be constructed by the longer inner wall of the isolation sleeve, thereby reducing the generation of condensate.

[0025] Optionally, the outer diameter of the mist outlet pipe is smaller than the outer diameter of the atomizing assembly, the sealing isolation portion comprises a wide diameter section and a narrow diameter section, and when the sealing isolation portion is in the first position, the wide diameter section is interference-fitted to the outer surface of the atomizing assembly; the narrow diameter section is interference-fitted to the outer surface of the mist outlet pipe;

[0028] Optionally, a give-way groove is further provided at the upper end of the atomization assembly corresponding to the connecting arm. When the sealing isolation part is in the first position, the connecting arm is inserted into the give-way groove.

[0029] Optionally, the depth of the give-way slot is greater than the thickness of the connecting arm.

[0030] Optionally, the inner wall of the sealing isolation portion is further provided with a reinforcing rib, which is located above the connecting arm and connected to the connecting arm, and when the sealing isolation portion is in the first position, the reinforcing rib and the connecting arm are both inserted into the give way groove.

When the end of the control part exposed to the outside world is subjected to force, the sealing isolation part is pulled from the first position to the second position by the connecting arm. At this time, the connecting arm slides along the avoidance chute. Therefore, the mist outlet pipe and the atomization assembly can be set closer, and there is no need for a large space for the control part and the sealing isolation part to move to the connection position. Therefore, when the sealing isolation part moves to the second position and the sealing isolation part is separated from the control part, the atomization gas path is mainly constructed by the inner wall of the mist outlet pipe and the atomization assembly, and does not need to be constructed by a longer inner wall of the isolation sleeve, thereby effectively reducing the generation of condensate.

[0051] See also Figures 1 to 8 The embodiment of the present application provides an atomizer cartridge 100, which includes a main body 10, an atomizer assembly 30, and an isolation sleeve 50. The main body 10 includes a shell 11 and a base 12. The shell 11 is open at one end and has a mist outlet at the other end. A mist outlet tube 111 is protruding from the inner wall of the main body 10, surrounding the mist outlet. The base 12 is plugged into the opening at one end of the shell 11 and, together with the inner wall of the main body 10, forms a liquid storage chamber 13. The liquid storage chamber 13 can store water, aromatic liquid, mosquito repellent liquid, medicinal liquid, tobacco liquid, etc., so that the atomizer device formed by combining with the atomizer cartridge 100 can be used as a humidifier, aromatherapy, mosquito repellent, medical atomizer, electronic cigarette, etc. In this embodiment, the solution to be atomized is tobacco liquid, and the atomizer device is an electronic cigarette.

[0052] like Figures 1 to 4 As shown, the atomization assembly 30 includes an atomization tube 31 and an atomization core 32 constructed in the atomization tube 31. The atomization tube 31 can be made of plastic or metal. In this embodiment, a thin-walled steel tube is used to reduce the occupied space. The atomization core 32 includes a liquid guide made of a material with solution adsorption performance and a heating element in contact with the liquid guide. The liquid guide can be made of one or a combination of non-woven fabrics, organic cotton, ceramics, etc. The heating element is a resistance heating wire or a heating mesh, etc. In this embodiment, the liquid guide member is made of cotton material, and the heating element is a heating net wrapped by the liquid guide member. One end of the atomizing tube 31 is mounted on the base 12, and the other end extends into the liquid storage chamber 13. A liquid inlet 311 is also provided on the outer wall of the portion of the atomizing tube 31 extending into the liquid storage chamber 13. The liquid guide member is used to block the liquid inlet hole so that the solution flowing into the liquid inlet hole is adsorbed by the liquid guide member and transferred to the heating element. The heating element atomizes the solution into aerosol under the action of electric current.

[0053] like Figure 1 Combine Figure 2As shown, the isolation sleeve 50 includes a sealed isolation portion 52 and a connected control portion 51. The sealed isolation portion 52 and the control portion 51 are integrally molded from a flexible material such as silicone or rubber. In this embodiment, silicone is preferably used. The sealed isolation portion 52 is hollow and tubular, while the control portion 51 is rod-shaped, with one end extending into the sealed isolation sleeve 50 and the other end extending to the outside along the mist outlet pipe 111. When the control portion 51, located outside, is subjected to external tension, the sealed isolation portion 52 can be pulled from the first position to the second position.

[0054] like Figure 1 As shown, when the sealing isolation portion 52 is in the first position, one end is sleeved on the outer wall of the atomizer assembly 30 and covers the liquid inlet 311, and the other end is sleeved on the outer periphery of the mist outlet pipe 111, thereby isolating the atomizer core 32 and the liquid storage chamber 13 in the internal space of the atomizer assembly 30, effectively preventing the solution to be atomized in the liquid storage chamber 13 from flowing into the interior of the atomizer assembly 30 through the liquid inlet 311 during transportation, resulting in leakage after exceeding the adsorption capacity limit of the liquid guide member.

[0055] like Figure 2 As shown, when the user uses it, he pulls the operating part 51, so that the sealing isolation part 52 is pulled toward the mist outlet pipe 111 to the second position, and the side wall originally covering the liquid inlet 311 is pulled upward to expose the liquid inlet 311 in the liquid storage chamber 13, so that the liquid storage chamber 13 and the internal liquid path of the atomization assembly 30 are connected; at this time, the solution to be atomized inside the liquid storage chamber 13 can flow along the liquid inlet 311 to be adsorbed by the liquid guide member.

[0056] Furthermore, if Figure 1 、 Figure 3 Combine Figure 5 、 Figure 8As shown, in this embodiment, the end of the mist outlet pipe 111 located in the liquid storage chamber 13 is further provided with an avoidance chute 1111, and the avoidance chute 1111 extends along the axial direction of the mist outlet pipe 111; the inner wall of the sealing isolation portion 52 is protruded with a connecting arm 521, and the operating portion 51 is connected to the protruding end of the connecting arm 521. When the operating portion 51 is forced to pull the sealing isolation portion 52 from the first position to the second position, the connecting arm 521 slides along the avoidance chute 1111. Since the avoidance chute 1111 is provided for the connecting arm 521 to slide through, the mist outlet pipe 111 and the atomization assembly 30 can be arranged closer. Thereby, the atomization gas route is constructed by the space inside the mist outlet pipe 111 and the space inside the atomization assembly 30, and only the area where the avoidance chute 1111 is provided in the mist outlet pipe 111 is filled and formed by the connecting arm 521. This effectively solves the problem that the entire outer circumference of one end of the traditional control part 51 is connected to the sealed isolation part 52, and a longer sliding stroke needs to be reserved. As a result, after the control part 51 is separated from the sealed isolation part 52, the air path between the mist outlet pipe 111 and the atomization component 30 needs to be constructed by the sealed isolation part 52, which makes it easy for condensation to occur.

[0057] Specifically, if Figure 3 As shown, in the embodiment of the present application, the mist outlet pipe 111 and the atomizer assembly 30 are coaxially arranged, and the distance between the plane where the lower end face of the mist outlet pipe 111 is located and the plane where the upper end face of the atomizer assembly 30 is located is between -2mm and 2mm, that is, the mist outlet pipe 111 can be slightly embedded in the atomizer pipe 31 or slightly higher than the atomizer pipe 31 or flush with the upper end face of the atomizer pipe 31; in this embodiment, it is preferred that the plane where the lower end face of the mist outlet pipe 111 is located coincides with the plane where the upper end face of the atomizer pipe 31 is located, that is, they are flush, so that the aerosol generated by the atomization of the atomizer core 32 directly enters the mist outlet pipe 111, effectively reducing contact with the sealing isolation component and reducing the generation of condensate.

[0058] Specifically, in order to enhance the connection stability and prevent the operating part 51 from unilaterally pulling the sealing isolation member, which may cause the sealing isolation member to deviate from the position, Figure 5 As shown, in the embodiment of the present application, the number of the connecting arms 521 is two, and the two connecting arms 521 are symmetrically arranged on the inner walls on both sides of the sealed isolation part 52. One end of the operating part 51 is located between the two connecting arms 521 and is connected to the two connecting arms 521, so that one end of the operating part 51 is suspended in the sealed isolation part 52; the mist outlet pipe 111 is correspondingly provided with two avoidance grooves 1111. When the operating part 51 is pulled by force to move the sealed isolation part 52 from the first position to the second position, the two connecting arms 521 slide along the two avoidance grooves 1111.

[0059] It is understood that in actual use, the two connecting arms 521 are not limited to being symmetrically protruding on both sides of the sealing isolation portion 52. For example, a staggered protrusion arrangement is also possible. In this embodiment, a symmetrical arrangement is adopted because it can provide pulling force on opposite sides, making pulling more stable. At the same time, the symmetrical arrangement makes the two avoidance chutes 1111 provided on the mist outlet pipe 111 easier to process and form.

[0060] Specifically, in order to prevent the connection arm 521 from breaking at the connection position with the sealing isolation portion 52 during the pulling process, Figure 5 As shown, in this embodiment, the connecting arm 521 gradually shrinks from the protruding head end to the protruding end end, that is, the connection area between the connecting arm 521 and the sealing isolation part 52 is relatively large, and the whole is fan-shaped.

[0061] Furthermore, if Figure 1 Combine Figure 5 As shown, the operating part 51 and the connecting arm 521 are connected by a thin-walled connecting part 53, and the thickness of the thin-walled connecting part 53 is less than the thickness of the connecting arm 521. When the operating part 51 pulls the connecting arm 521 to slide to the tail end of the avoidance chute 1111, the connecting arm 521 abuts against the groove wall at the tail end of the avoidance chute 1111. When further force is applied, the thin-walled connecting part 53 breaks, and the operating part 51 and the connecting arm 521 are separated and pulled out of the mist outlet pipe 111. By providing the thin-walled connecting part 53, the weak point between the operating part 51, the connecting arm 521 and the sealing isolation part 52 is at the thin-walled connecting part 53. When the pressure is large, it breaks here, thereby avoiding the phenomenon of liquid leakage caused by the rupture of the connecting arm 521 and the sealing isolation part 52 during the pulling process.

[0062] Specifically, if Figure 6 As shown, the thickness D of the thin-walled connecting portion 53 is 10% to 70% of the thickness d of the connecting arm 521. Furthermore, the thin-walled connecting portion 53 is connected to the middle portion of the connecting arm 521 in the sliding direction, further refining the breaking position and improving product yield. It is understood that in actual use, the thin-walled connecting portion 53 is not limited to the middle portion of the connecting arm 521 in the sliding direction of the embodiment described above. For example, arrangements located above or below the connecting arm 521 are also within the scope of protection of the present invention.

[0063] Specifically, the thickness of the connecting arm 521 is between 1.5mm and 4mm, for example, 1.5mm, 2mm, 3mm, etc. The thickness of the thin-walled connecting portion 53 is between 0.15mm and 2.8mm, for example, 0.15mm, 0.8mm, 1mm, 2mm, etc., which are not limited here. In this embodiment, it is preferred to adopt the quantity that has been verified by multiple tests, specifically the thickness of the connecting arm 521 is 2mm, and the thickness of the thin-walled connecting portion 53 is 0.8mm, which is convenient for silicone processing and molding.

[0064] Specifically, if Figure 1 Combine Figure 8 As shown, the notch on the end face of the avoidance chute 1111 is gradually expanded to form a guide opening 1112. The width of the guide opening 1112 is greater than the width of the connecting arm 521, and the width of the rear section of the avoidance chute 1111 is less than or equal to the width of the connecting arm 521. As the connecting arm 521 slides along the guide opening 1112 into the inner section of the avoidance chute 1111, the force applied thereto gradually increases, effectively improving the user's operational feel. At the same time, the gradually expanded guide opening 1112 provides guidance, resulting in a small clearance fit during initial sliding in, and the device can accurately slide into the avoidance chute 1111, preventing the device from abutting and breaking against the notch end face of the avoidance chute 1111.

[0065] Furthermore, if Figure 3 As shown, the outer diameter of the mist outlet pipe 111 is smaller than the outer diameter of the atomizer assembly 30, and the sealing isolation portion 52 includes a wide diameter section 523 and a narrow diameter section 524. When the sealing isolation portion 52 is in the first position, the wide diameter section 523 is interference-fitted on the outer surface of the atomizer assembly 30; the narrow diameter section 524 is interference-fitted on the outer surface of the mist outlet pipe 111; when the sealing isolation portion 52 is pulled from the first position to the second position by force, the position where the wide diameter section 523 and the narrow diameter section 524 are connected is separated from the atomizer assembly 30, and the interval surrounds the outer circumference of the mist outlet pipe 111. Here, the sealing isolation portion 52 is formed into a wide diameter section 523 and a narrow diameter section 524, the wide diameter section 523 is sleeved on the mist outlet pipe 111 with a larger outer diameter, and the narrow diameter section 524 is sleeved on the mist outlet pipe 111 with a smaller outer diameter. When pulled, the upper end of the wide diameter section 523 is separated from the atomizing pipe 31 and surrounds the outer circumference of the mist outlet pipe 111, thereby reducing friction and making the pulling smoother.

[0066] Specifically, if Figure 6As shown, the wall thickness of the wide diameter section 523 is less than that of the narrow diameter section 524, and the inner walls of the wide diameter section 523 and the narrow diameter section 524 are both provided with sealing ridges 525. Here, in this embodiment, the wall thickness of the wide diameter section 523 is less than that of the narrow diameter section 524, so the covering force and friction force at the wide diameter section 523 are relatively small, which facilitates pulling and prevents the thin-walled connection 53 from breaking during the pulling process due to being connected to the two connecting arms 521 only by two thin-walled connecting parts 53. At the same time, the inner walls of the wide diameter section 523 and the narrow diameter section 524 are both provided with sealing ridges 525. The sealing ridges 525 are tightly sealed with the outer periphery of the atomizing tube 31 and the outer periphery of the mist outlet tube 111 to prevent the entire surface from being too tight and causing high friction. In addition, the sealing by the sealing ridge 525 has lower requirements for processing accuracy compared to the interference sealing of the entire surface. If the surface is sealed, when one surface is not smooth during processing, gaps are likely to appear, resulting in leakage, which effectively improves the product yield.

[0067] Furthermore, if Figures 1 to 4 As shown, a give-way groove 312 is further provided at the upper end of the atomizer assembly 30 corresponding to the connecting arm 521. When the sealing isolation portion 52 is in the first position, the connecting arm 521 is inserted into the give-way groove 312. When the sealing isolation portion 52 is forced to move from the first position to the second position, the connecting arm 521 slides from the give-way groove 312 into the avoidance groove 1111. Here, in this embodiment, a give-way groove 312 is further provided at the upper end of the atomizing tube 31 corresponding to the connecting arm 521. During processing and production, the sealing isolation portion 52 is pre-sleeved on the outer wall of the atomizing tube 31, and the connecting arm 521 is pre-installed in the give-way groove 312, so as to achieve precise positioning and installation. Compared with the method of designing the avoidance groove 1111 to be longer and pre-installing the sealing isolation portion 52 in the avoidance groove 1111, the give-way groove 312 is designed and the connecting arm 521 is pre-installed in the give-way groove 312. Since the atomizing tube 31 of the atomizing assembly 30 is directly exposed above the base 12 during assembly, and the mist outlet pipe 111 is located inside the shell 11, installation is more convenient.

[0068] Furthermore, if Figure 3 Combine Figure 4 As shown, the depth of the relief groove 312 is greater than the thickness of the connecting arm 521, and the thickness of the avoidance groove 1111 is equal to the thickness of the connecting arm 521. Therefore, the space above the atomizer core 32 in the atomizer tube 31 can be larger, preventing the sealing isolation portion 52 and the atomizer outlet pipe 111 from being too close to the atomizer core 32 that mainly generates heat, resulting in long-term damage due to high temperature.

[0069] Furthermore, if Figure 7As shown, the inner wall of the sealing isolation portion 52 is further provided with a reinforcing rib 522, and the reinforcing rib 522 is located above the connecting arm 521 and is connected to the connecting arm 521. When the sealing isolation portion 52 is in the first position, the reinforcing rib 522 and the connecting arm 521 are both inserted into the give way slot 312. By providing the reinforcing rib 522, the connection strength between the connecting arm 521 and the isolation sealing portion is effectively enhanced, and the connection arm 521 and the isolation sealing portion are further prevented from being broken. At the same time, it can also prevent the sealing isolation portion 52 from being pre-installed on the outside of the atomizer tube 31 due to a large insertion force, causing the connecting arm 521 to be deformed and deviate toward the reinforcing rib 522.

[0070] Specifically, if Figure 3 Combine Figure 4 As shown, the upper end of the atomizer core 32 is flush with the lower end of the yielding slot 312, and the space inside the atomizer tube 31 at the upper end of the atomizer core 32 forms an accommodating space for the connecting arm 521 and one end of the control portion 51; and when the sealing isolation portion 52 moves to the second position, the space inside the atomizer tube 31 at the upper end of the atomizer core 32 forms an air flow channel 60 that communicates with the internal space of the mist outlet pipe 111.

[0071] Specifically, if Figure 1 As shown, in the embodiment of the present application, when the sealing isolation sleeve 50 is in the first position, the connecting arm 521 passes through the clearance groove 312 and is located in the atomizer tube 31, and abuts against the upper surface of the atomizer core 32; thereby achieving precise positioning and installation, and increasing a greater supporting force, preventing the connecting arm 521 from being scratched by the bottom groove wall of the clearance groove 312.

[0072] Specifically, if Figure 3 As shown, in the embodiment of the present application, when the sealing isolation sleeve 50 is in the second position, the end face of the protruding end of the connecting arm 521 is smoothly adapted to the inner wall of the mist outlet pipe 111, preventing the connecting arm 521 from protruding into the airflow channel 60, blocking the airflow and easily causing condensation.

[0073] Furthermore, the present application also provides an atomization device, which includes a power supply device (not shown) and an atomization cartridge 100. When the atomization cartridge 100 is installed in the power supply device, it establishes an electrical connection with the power supply device. The specific structure of the atomization cartridge 100 is referenced from the above embodiments. Since the atomization device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
