  • DESCRIPTION OF EMBODIMENTS
  • The present application will be further illustrated in conjunction with the drawings and specific embodiments so that those skilled in the art can better understand the present application and can implement it, but the embodiments are not intended to limit the present application.
  • The present application provides an atomizing head including a heating member 10, a sleeve and two electrical contact ends 40. The sleeve is sleeved on an outer surface of the heating member 10. The two electrical contact ends 40 are respectively disposed at two ends of the sleeve. The heating member 10 and the sleeve are insulated from each other. The electrical contact ends 40 and the sleeve are insulated from each other. The heating member 10 has wiring ends 12 at both ends respectively, and each of the wiring ends 12 is electrically connected to a corresponding one of the electrical contact ends 40, so that the atomizing head can be connected, at either end, to a positive electrode or a negative electrode through the electrical contact end 40. There will be no circuit problem resulting from a wrong connection between the positive electrode and the negative electrode, thus no distinction between the positive electrode and the negative electrode is needed for the atomizing head during assembly, therefore, quick mounting and dismounting may be realized.
  • In the present application, in order to ensure that the liquid smoke can be brought into contact with the heating member 10 in a proper and uniform manner, the atomizing head further includes a liquid adsorbing member 20, where the liquid adsorbing member 20 is wrapped around the outer surface of the heating member 10, or the liquid adsorbing member 20 and the heating member 10 are integrally formed. The sleeve is sleeved on an outer circumference of an integration of the heating member 10 and the liquid adsorbing member 20, and the sleeve is provided with a liquid inlet passage 32 for guiding liquid smoke onto the liquid adsorbing member 20. It should be noted that the sleeve is sleeved on the outer circumference of the integration of the heating member 10 and the liquid adsorbing member 20, which means: if the liquid adsorbing member 20 is wrapped around the outer surface of the heating member 10, the sleeve is sleeved on an outer circumference of the liquid adsorbing member 20; if the liquid adsorbing member 20 and the heating member 10 are integrally formed, the sleeve is sleeved on an outer circumference of the integrally formed structure.
  • First Embodiment
  • Reference may be made to FIG. 1 to FIG. 5. In the first embodiment provided in the present application, the sleeve is a metal tube 30 a with a hollow structure inside, that is, the metal tube 30 a has a through hole extending in an axial direction. The liquid adsorbing member 20 is wrapped around an outer surface of the heating member 10, and the metal tube 30 a is further sleeved on an outer surface of the liquid adsorbing member 20 to form a layer-by-layer progressive structure. Since the metal tube 30 a has a liquid inlet passage 32 thereon, the liquid smoke enters the liquid absorbent member 20 through the liquid inlet passage 32 to reach the heating member 10. The heating member 10 generates heat in a power on state, and the liquid smoke is heated to generate smog. A through hole along an axial direction of the metal tube 30 a can serve as a flow passage for smog and air flow.
  • Reference may be further made to FIG. 2 and FIG. 5. The atomizing head further includes insulating pads 50 located at both ends of the metal tube 30 a. Each of the insulating pads 50 is clamped between the electrical contact end 40 and the metal tube 30 a. Therefore, when the wiring end 12 of the heating member 10 is electrically connected to the electrical contact end 40, the presence of the insulating pad 50 would cause an insulation between the electrical contact end 40 and the metal tube 30 a.
  • The insulating pad 50 includes a first positioning portion 52. The first positioning portion 52 protrudes into a tube wall at one end of the metal tube 30 a. Of course, an outer contour of the first positioning portion 52 is shape-matched with an inner contour of the tube wall of the metal tube 30 a to achieve the best effect when both of them are in close contact with each other. In addition, an end of the first positioning portion 52 protrudes into an end of the liquid adsorbing member 20 for abutting. First positioning portions 52 inside the tube wall and at both ends of the metal tube 30 a can make an abutment of the liquid adsorbing member 20 between the two first positioning portions 52 to prevent the liquid adsorbing member 20 from moving axially within the metal tube 30 a, thereby improving the assembly reliability of the atomizing head. Further, the insulating pad 50 also includes a first flange 54 located at one end of the first positioning portion 52 away from a direction where the liquid adsorbing member 20 is located. The first flange 54 protrudes outwardly along the end of the first positioning portion 52. A diameter of the first flange 54 is greater than an inner diameter of the metal tube 30 a. When the insulating pad 50 is mounted, the first flange 54 is abutted, at a side close to the liquid adsorbing member 20, against an end of the metal tube 30 a, which functions as positioning the first positioning portion 52 and prevents the first positioning portion 50 from protruding into the metal tube 30 a at a further length. Of course, in order to facilitate the abutment of the first flange 54 to increase the assembly reliability, both ends of the metal tube 30 a can correspondingly extend outwardly to a protruding portion that matches the first flange 54. Further, the first positioning portion 52 and the first flange 54 each have an axial through hole.
  • The electrical contact end 40 includes a second positioning portion 42 and a second flange 44 located at one end of the second positioning portion 42 away from the liquid adsorbing member 20. The second positioning portion 42 protrudes into the through hole of the first positioning portion 52 and the first flange 54. A diameter of the second flange 44 is larger than an inner diameter of the through hole of the first flange 54. The second flange 44 is abutted, at a side close to the liquid adsorbing member 20, against an end of the first flange 54 away from the liquid adsorbing member 20, and the wiring end 12 is clamped between an inner wall of the first positioning portion 52 and an outer wall of the second positioning portion 42, so that the wiring end 12 can be fixed, and a reliable conductive connection between the wiring end 12 and the electrical contact end 40 can be ensured without welding or other processes. The second flange 44 increases a contact area between the electrical contact end 40 and a power resource of the electronic cigarette, further increasing reliability of the conductive connection.
  • The liquid adsorbing member 20 may be made of at least one of the following insulating porous materials: a cotton, a cotton cloth, a fiber rope, or a porous ceramic, so that the heating member 10 and the metal tube 30 a are insulated from each other. The insulated porous material described above can not only guide the liquid smoke to the heating member 10 uniformly, but also can function to store the liquid smoke to some extent.
  • The heating member 10 may be in the form of a resistance wire. In the present embodiment, the resistance wire forms a solenoid structure, and the liquid adsorbing member 20 is wrapped around the surface of the heating member 10 and is in close contact with the heating member 10, so that it is convenient for the liquid smoke to be brought into contact with the heating member 10 evenly. Moreover, a cavity inside the solenoid can cause a smooth flow of the generated smog.
  • Second Embodiment
  • Reference may be made to FIG. 6 to FIG. 8. In a second embodiment provided in the present application, the sleeve is a ceramic supporting tube 30 b. Since the ceramic material itself is not conductive, in the present embodiment, the insulating pad 50 of the first embodiment can be omitted. The liquid adsorbing member 20 is wrapped around an outer surface of the heating member 10, and the ceramic supporting tube 30 b is further sleeved on an outer surface of the liquid adsorbing member 20 to form a layer-by-layer progressive structure. The ceramic supporting tube 30 b has a positioning step at its inner wall. An electrical contact end 40 is embedded into the ceramic supporting tube 30 b. An end of the electrical contact end 40 is abutted against the positioning step. Two ends of the liquid adsorbing member 20 in an axial direction are abutted against two electrical contact ends 40, which can axially position the liquid adsorbing member 20 to prevent the liquid adsorbing member 20 from moving axially within the ceramic supporting tube 30 b, thereby improving the assembly reliability of the atomizing head. The wiring end 12 is clamped between an outer wall of the electrical contact end 40 and the inner wall of the ceramic supporting tube 30 b, so that the wiring end 12 can be fixed, and a reliable conductive connection between the wiring end 12 and the electrical contact end 40 can be ensured without welding or other processes.
  • In the present embodiment, the liquid adsorbing member 20 is made of at least one of the following materials: a cotton, a cotton cloth, a fiber rope, a porous ceramic, a foam metal, or a foam graphite.
  • In one of implementations, a side wall of the ceramic supporting tube 30 b has an open structure, that is, a hollow shape, and its hollow space constitutes the liquid inlet passage 32.
  • In one of implementations, the atomizing head further includes a leakage-proof member 60. In the present embodiment, the hollow space on the side wall of the ceramic supporting tube 30 b is used as the liquid inlet passage 32. The liquid inlet passage 32 is relatively large, so that the liquid inlet amount is also large. Therefore, there is a risk of liquid leakage. In order to prevent the liquid leakage, the leakage-proof member 60 is also disposed on an outer circumference of the hollow space. Of course, the leakage-proof member 60 also needs to have a function of guiding the liquid smoke onto the liquid adsorbing member 20. In the present embodiment, the leakage-proof member 60 is made of a cotton.
  • Third Embodiment
  • The present application also provides a third embodiment which is not shown in the drawings. The difference between the present embodiment and the second embodiment described above lies in that the liquid adsorbing member 20 is made of a porous ceramic. In order to ensure a close contact between the liquid adsorbing member 20 made of porous ceramic and the heating member 10 for better guiding liquid smoke, the heating member 10 and the liquid adsorbing member 20 made of the porous ceramic has an integrated structure, specifically, the integrated structure may be formed by sintering. There is an axial through hole inside the integrated structure to facilitate flow of the smog.
  • It can be understood that, in the first embodiment, the structure where the liquid adsorbing member 20 is wrapped around the outer surface of the heating member 10 can also be replaced with the integrated structure formed by the heating member 10 and the liquid adsorbing member 20 made of the porous ceramic in the present embodiment.

The conductive sleeve 30 is sleeved on an outer surface of the liquid adsorbing member 20. Since the liquid adsorbing member 20 is insulated, the heating member 10 and the conductive sleeve 30 spaced by the liquid adsorbing member 20 are insulated from each other. The conductive sleeve 30 is provided a liquid inlet passage 32 for guiding liquid smoke onto the liquid adsorbing member 20. The conductive sleeve 30 has a through hole in an axial direction therein. The heating member 10 has a wiring end 12 a and a second wiring end 14, where the first wiring end 12 a and the second wiring end 14 are both located at the same end of the conductive sleeve 30 (for example, the left end shown in FIG. 9). The atomizing head also includes an insulating pad 40 a and an electrical contact end 50 a. The insulating pad 40 a is clamped between the electrical contacting end 50 a and the conductive sleeve 30 to cause an insulation between the conductive sleeve 30 and the electrical contact end 50 a. The first wiring end 12 a is electrically connected to the conductive sleeve 30, and the second wiring end 14 is electrically connected to the electrical contact end 50 a. During assembly, either one of the electrical contact end 50 a and an end of the conductive sleeve 30 away from the electrical contact end 50 a is electrically connected to the positive electrode of the power source of the electronic cigarette, and the other one of the electrical contact end 50 a and the end of the conductive sleeve 30 away from the electrical contact end 50 a is electrically connected to the negative electrode of the power source of the electronic cigarette. There will be no circuit problem resulting from a wrong connection between the positive electrode and the negative electrode, thus no distinction between the positive electrode and the negative electrode is needed for the atomizing head during assembly. Moreover, the atomizing head of the present application has a simple structure; therefore, quick mounting and dismounting can be realized.
  • It should be noted that, the first wiring end 12 a and the second wiring end 14 are only used to conveniently distinguish the name. The difference between the two names does not mean that there is a difference in the structure of the two wiring ends, and the positions of the two wiring ends are interchangeable. That is, in embodiments not shown, the name of the first wiring end 12 a and the name of the second wiring end 14 can be exchanged.

The liquid adsorbing member 20 is wrapped around an outer surface of the heating member 10. The conductive sleeve 30 is further sleeved on an outer surface of the liquid adsorbing member 20 to form a layer-by-layer progressive structure. Since the conductive sleeve 30 has a liquid inlet passage 32 thereon, the liquid smoke enters the liquid adsorbing member 20 through the liquid inlet passage 32 to reach the heating member 10. The heating member 10 generates heat in a power on state, and the liquid smoke is heated to generate smog. The through hole along the axial direction of the conductive sleeve 30 can serve as a flow passage for smog and air flow.

The first flange 44 a is abutted, at a face end facing the conductive sleeve 30, against an end of the conductive sleeve 30 so as to limit the length of the first positioning portion 42 protruding into the conductive sleeve 30. Further, reference may be made to FIG. 10 to FIG. 13, where the conductive sleeve 30 has, at an end close to the insulating pad 40 a, an outwardly extending boss. The boss facing is aligned, at a side facing the insulating pad 40 a, with the end of the conductive sleeve 30, and is abutted against a corresponding side of the first flange 44 a; therefore, it is possible to increase a contact area between the first flange 44 a and the conductive sleeve 30, and increase the assembly reliability.

In this way, one end of the liquid adsorbing member 20 is abutted against an end of the first positioning portion 42 a, and the other end is abutted against the axially positioning portion 34, so that the liquid adsorbing member 20 can be prevented from protruding along an axial direction of the conductive sleeve 30. The axially positioning portion 34 can also provide a large contact area when the conductive sleeve 30 is electrically connected to the power source of the corresponding electronic cigarette, so as to ensure the reliability of the power connection. Of course, the conductive sleeve 30 and the axially positioning portion 34 may have separate structures or an integrated structure.
  • The liquid adsorbing member 20 is made of at least one of the following materials: a cotton, a cotton cloth, a fiber rope, or a porous ceramic.
