Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette substitute technology, and in particular to a square atomizing core, its atomizer, and an electronic cigarette. Background Technology
[0002] Electronic atomizing devices are electronic products that mimic cigarettes, atomizing e-liquid into vapor for users to inhale. Due to their similar taste and ease of use to cigarettes, electronic atomizing devices have been rapidly promoted and used.
[0003] Existing electronic atomizing devices generally include a battery main unit and an atomizer. The atomizer is the vapor-generating part of the electronic atomizing device, containing e-liquid. High temperatures cause the e-liquid to atomize and form vapor. The battery main unit is the control center and power supply unit of the electronic atomizing device. The atomizer coil connects to and absorbs e-liquid, which is then drawn to the heating wire. When electricity is applied, the heating wire generates high-temperature atomization of the e-liquid.
[0004] With the improvement and innovation of atomizer core technology, various atomizer cores have emerged, including those with cotton-wrapped fibers, cotton-wrapped fibers, and cotton-wrapped mesh. Based on placement, there are horizontal and vertical cores. For vertical cotton-wrapped mesh atomizer cores, the assembly method is always a winding process. Specifically, the heating mesh and absorbent cotton are wound together and then installed in a circular steel tube to form a separate assembly. However, this assembly method requires bending and deforming using a mold, which is difficult, labor-intensive, and prone to problems such as heating mesh deformation, poor adhesion between the heating mesh and absorbent cotton leading to wire burn, affecting taste and lifespan. Utility Model Content
[0005] Therefore, it is necessary to provide a square atomizing core, its atomizer, and electronic cigarette that can be automated, where the heating mesh does not need to be wound during assembly, can be directly attached, and is not easily deformed.
[0006] A square atomizing core includes a square air guide tube, a heating element, and a liquid absorption element. The square air guide tube has an oil guide hole. The heating element is attached to the outer wall of the square air guide tube and blocks the oil guide hole. The liquid absorption element is sleeved on the square air guide tube at the position of the heating element.
[0007] In one embodiment, the heating element is a heating mesh or a heating element.
[0008] In one embodiment, the heating element is welded and fixed to the square air duct.
[0009] In one embodiment, the heating element is symmetrically provided with positioning holes around its periphery, and the square air guide tube is provided with screw holes that are adapted to the positioning holes. The heating element is fixed to the square air guide tube by screws through the positioning holes and screw holes.
[0010] In one embodiment, a positioning frame is recessed on the outer wall of the square air duct, and the heating element is embedded in the positioning frame.
[0011] In one embodiment, the oil guide hole is a square hole or a round hole, and the shape of the heating element is adapted to the oil guide hole.
[0012] In one embodiment, the oil guide hole is provided on two opposing walls of the square air guide tube, or the oil guide hole is provided on all four walls of the square air guide tube.
[0013] An atomizer includes a housing, a base, and the aforementioned atomizing core. The housing includes a mouthpiece and an open end. The base is inserted into the open end and forms a hollow cavity inside the housing. The hollow cavity is divided into an oil storage chamber and an atomizing chamber by a square air guide tube. The oil storage chamber is filled with liquid storage cotton. The square air guide tube is connected to the mouthpiece.
[0014] An electronic cigarette includes a battery main unit and the aforementioned atomizer, the atomizer being adapted to the battery main unit.
[0015] The aforementioned square atomizer core has at least the following advantages:
[0016] The atomizing core uses a square air guide tube, which serves as both a support and air guide. When assembling the heating element, a single heating element can be directly attached and fixed to the outer wall of the square air guide tube. If heating elements need to be installed on two or more sides of the square air guide tube, they can be directly attached and fixed to each side separately, eliminating the need to wind the heating element and preventing deformation. A square, hollow liquid-absorbing element is fitted over the square air guide tube. The liquid-absorbing element fits tightly to both the outer wall of the square air guide tube and the heating element, resulting in uniform atomized smoke, a good inhalation experience, and preventing dry burning due to loose fit. The assembly is simple, facilitating automated assembly and significantly reducing labor costs. Attached Figure Description

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0023] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0025] Please see Figure 1 This is an exploded view of the square atomizing core 10 in one embodiment.
[0026] A square atomizing core 10 includes a square air guide tube 12, a heating element 14, and a liquid absorption element 16. The square air guide tube 12 has an oil guide hole 122. The heating element 14 is attached to the outer wall of the square air guide tube 12 and blocks the oil guide hole 122. The liquid absorption element 16 is sleeved on the square air guide tube 12 at the heating element 14.
[0027] The atomizing core 10 uses a square air guide tube 12, which serves as a support and air guide. When assembling the heating element 14, a single heating element 14 can be directly attached and fixed to the outer wall of the square air guide tube 12. If heating elements 14 need to be installed on two or more sides of the square air guide tube 12, they can be directly attached and fixed to each side respectively, without the need to wind the heating element 14, thus preventing deformation of the heating element 14. Please refer to [link / reference]. Figure 3A square hollow liquid-absorbing element 16 is fitted outside the square air duct 12. The liquid-absorbing element 16 can be tightly fitted to the outer wall of the square air duct 12 and the heating element 14, so that the atomized smoke is uniform, the taste is good, and there will be no dry burning problem due to poor fit. The assembly is simple, which is conducive to the realization of automated assembly and greatly reduces labor costs.
[0028] In this embodiment, the heating element 14 is a heating mesh or heating plate. Because the heating mesh or heating plate has a relatively large area compared to the heating wire, it is prone to deformation due to uneven stress when bent. Therefore, using a method that fits the square air guide tube 12 helps to reduce deformation. The heating wire is mainly used to wind the liquid absorption element 16, so a heating wire is not selected in this embodiment.
[0029] In this embodiment, the heating element 14 is symmetrically provided with positioning holes around its periphery, and the square air guide tube 12 is provided with screw holes 124 that are adapted to the positioning holes. The heating element 14 is fixed to the square air guide tube 12 by screws through the positioning holes and screw holes 124. Screw holes 124 are provided around the oil guide hole 122. When the heating element 14 is stamped, positioning holes corresponding to the screw holes 124 can be punched. During assembly, the stamped heating element 14 is directly aligned with the screw holes 124 and screwed in for fixing. This can achieve mechanized precise matching and automated assembly, greatly reducing labor costs. The heating mesh or heating element can also be provided with multiple lugs, and the positioning holes are located at the lugs.
[0030] In another example, the heating element 14 is welded and fixed to the square air duct 12. The welding method is also convenient to operate and can be automated.
[0031] In another embodiment, a positioning frame is recessed on the outer wall of the square air guide tube 12, and the heating element 14 is embedded in the positioning frame. During assembly, the heating element 14 can be precisely aligned with the positioning frame and then placed down using a machine, and then the liquid suction element 16 can be inserted, which can realize automated operation.
[0032] In this embodiment, the oil guide hole 122 is a square or round hole, and the shape of the heating element 14 is adapted to the oil guide hole 122. The oil guide hole 122 is a square or round hole with a regular shape, which is conducive to the even absorption of e-liquid by the suction element 16, and also facilitates the regular setting of the screw hole 124 of the square air guide tube 12 and the positioning hole of the heating element 14, simplifying automated operation.
[0033] In this embodiment, oil guiding holes 122 are provided on two opposing walls of the square air guiding tube 12, or oil guiding holes 122 are provided on all four walls of the square air guiding tube 12. Multiple oil guiding holes 122 are provided symmetrically. This facilitates rapid oil guiding, preventing dry burning due to insufficient e-liquid. Furthermore, it ensures even oil guiding, maintaining a stable flavor and preventing the localized suction element 16 from burning due to uneven oil guiding.
[0034] Of course, the liquid-absorbing element 16 is liquid-absorbing cotton. The liquid-absorbing cotton is made into a square shape that matches the square air guide tube 12. The liquid-absorbing cotton is also hollow tube-shaped. The square hole in the middle is generally the same size as the square air guide tube 12. The liquid-absorbing cotton is inserted from one end of the square air guide tube 12.
[0035] Please see Figure 2 , Figure 3 , Figure 4 This embodiment also includes an atomizer 20, which is a vapor-generating device for electronic cigarettes. It heats up when powered on, causing the e-liquid inside the atomizer 20 to form vapor for the user to inhale. The atomizer 20 includes a housing 22, a base 24, and an atomizing core 10. The atomizing core 10 includes all the technical features described above, and will not be repeated here. The housing 22 includes a mouthpiece 222 and an open end. The base 24 is inserted into the open end and forms a hollow cavity inside the housing 22. The hollow cavity is divided into an oil storage chamber 224 and an atomizing chamber 226 by a square air duct 12. The oil storage chamber 224 is filled with absorbent cotton. The square air duct 12 communicates with the mouthpiece 222. During assembly, the assembly of the square air duct 12 and absorbent cotton is placed inside the absorbent cotton to compress it, and then the whole assembly is placed inside the housing 22 and fixed, thus dividing the inside of the housing 22 into the oil storage chamber 224 and the atomizing chamber 226.
[0036] Please see Figure 2 , Figure 3 , Figure 4 This embodiment also includes an electronic cigarette, comprising a battery main unit 30 and an atomizer 20. The atomizer 20 is a vapor-generating device for the electronic cigarette, used to generate heat when powered on, so that the e-liquid inside the atomizer 20 forms vapor for the user to inhale. The battery main unit 30 is the control center and power supply center of the electronic cigarette. The battery provides power to the entire circuit of the electronic cigarette, enabling the control center to power on and control the various components in the circuit to work, so that the atomizer 20 can be powered on and heated. The atomizer 20 is compatible with the battery main unit 30.
[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
