Those skilled in the art can make modifications to the present embodiment without creative contribution after reading the present specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.

[0033] The embodiment relates to a metal-felt atomizer, which refers to Figures 1-2 and comprises an outer shell 1, an air guide pipe 2, a metal-felt heating body 3, a support 4 and an electrode column 5.

[0034] The outer shell 1 is a hollow long-cylindrical structure, which has a proximal end and a distal end opposite to each other in the axial direction; according to the general use requirement, the proximal end is configured as one end for a user to inhale aerosol and is provided with a smoking port a, and the distal end is configured as one end for assembly connection with a battery rod and is provided with an open end. The open end structure is used for mounting various necessary functional components inside the outer shell 1. A detachable base 6 is mounted on the open end, and the base 6 is provided with an air inlet channel for external air to enter.

[0035] The air guide pipe 2 is arranged in the outer shell 1 and is arranged along the axis. The space between the outer wall of the air guide pipe 2 and the inner wall of the outer shell 1 forms an oil reservoir b for storing a liquid substrate. The first end of the air guide pipe 2 relative to the proximal end is communicated with the smoking port a, and the second end relative to the distal end is connected with the metal-felt heating body 3, so that the metal-felt heating body 3 transmits the aerosol generated by atomizing the liquid substrate to the smoking port a for inhalation.

[0036] The metal-felt heating body 3 is vertically arranged in the outer shell 1 and is in a sheet shape, which is used for sucking the liquid substrate from the oil reservoir b and atomizing the liquid substrate. The metal-felt heating body 3 can adopt a parallel structure or a series structure, and in the embodiment, the metal-felt heating body 3 in the series structure is taken as an example. In addition, the metal-felt heating body 3 is made of metal fiber filaments with a diameter of 1-100 um and a length of 10-10000 um. The metal-felt heating body 3 can directly guide the liquid and atomize, and does not need to rely on an atomizing core (cotton core or ceramic core) and other oil guiding structures. A plurality of through holes are arranged on the surface of the metal-felt heating body 3, and the pattern of the plurality of through holes is not limited and can be a round hole, a square hole or other patterns. The metal-felt heating body 3 is a pure metal-felt heating body 3.

[0037] The support 4 is arranged in the outer shell 1 and is wrapped outside the metal-felt heating body 3 and is used for accommodating and retaining the metal-felt heating body 3. The support 4 and the metal-felt heating body 3 are each formed with an atomizing cavity c on the two sides. The support 4 is provided with a first oil inlet hole d and a first air exchange hole e which are communicated with the oil reservoir b. The liquid substrate is adsorbed to the metal-felt heating body 3 through the first oil inlet hole d. The first air exchange hole e is used for balancing the air pressure in the oil reservoir b and the external air pressure, and through the first air exchange hole e, the liquid substrate in the oil reservoir b can be smoothly guided to the metal-felt heating body 3 in the process of suction.

[0038] The electrode column 5 is mounted on the inner lower side of the outer shell 1, one end of the electrode column 5 is connected with the metal-felt heating body 3 and is used for supplying power to the metal-felt heating body 3 as an electrode after being connected with the electrically-conductive spring needle of the battery rod.

[0039] The metal felt heating body 3 is provided with two atomizing cavities c on both sides of the metal felt heating body 3. The two sides of the metal felt heating body 3 can adsorb liquid matrix and heat atomize. In addition, the metal felt heating body 3 is vertically placed, so that the contact area of the metal felt heating body 3 with the liquid matrix and air in the atomizing cavities c is increased, thereby greatly improving the atomization efficiency of the metal felt atomizer.

[0040] In order to facilitate the installation of the metal felt heating body 3, in the embodiment, as shown in Figure 1 and Figure 4 , the bracket 4 is assembled by the first bracket 414 and the second bracket 424. When assembling, the metal felt heating body 3 is assembled in one of the brackets 4, and then the other bracket 4 is combined. Further, the bottom of the first bracket 414 and the second bracket 424 is provided with a second air hole f along the axis. The lower end of the second air hole f is communicated with the air inlet channel on the base 6, and the upper end is communicated with the atomizing cavity c, and one second air hole f corresponds to one atomizing cavity c.

[0041] Specifically, in the embodiment, as shown in Figure 4 and Figure 5 , the first air hole e has two and is symmetrically arranged on the side wall of the first bracket 414. Due to the two symmetrically arranged first air holes e, the air exchange is uniform during the suction process. The first air hole e can be a square hole, a round hole or other hole shape. Since the metal felt atomizer has two atomizing cavities c, and the metal felt heating body 3 can heat and atomize on both sides, as shown in the figure, the first oil inlet hole d also has two, which are symmetrically arranged on the side wall of the first bracket 414. In the embodiment, the first oil inlet hole d is in the shape of a long strip. More specifically, in the embodiment, the first oil inlet hole d is communicated with the first air hole e. Of course, in other embodiments, the first air hole e and the first oil inlet hole d can be arranged on the second bracket 424, or part of them can be arranged on the first bracket 414 and part of them can be arranged on the second bracket 424.

[0042] Please refer to Figures 1-4 , the metal felt atomizer further comprises a silica gel sleeve 7. The silica gel sleeve 7 is sleeved on the outer side wall of the bracket 4. The silica gel sleeve 7 plays a sealing and protection role for the bracket 4. The silica gel sleeve 7 is provided with a second oil inlet hole g and a second air hole corresponding to the first oil inlet hole d and the first air hole e.

[0043] As shown in Figure 2 and Figure 4 , the lower end of the silica gel sleeve 7 is provided with a first annular structure 71 with a cross-sectional area larger than the sleeve body of the silica gel sleeve 7, and the outer side wall of the first annular structure 71 is provided with a first reinforcing rib 711. By providing the first reinforcing rib 711, the outer side wall of the lower end of the silica gel sleeve 7 is in interference fit with the inner side wall of the outer shell 1, and the sealing performance is more excellent.

[0044] The upper end of the silica gel sleeve 7 is provided with a second annular structure 72 with a smaller cross-sectional area than the sleeve body of the silica gel sleeve 7, and the inner side wall of the second annular structure 72 is provided with a second reinforcing rib 721. By providing the second reinforcing rib 721, the inner side wall of the upper end of the silica gel sleeve 7 is in interference fit with the outer side wall of the air guide pipe 2, and the sealing performance is more outstanding.

[0045] Please refer to Figure 1 and Figure 2 , the metal felt atomizer further comprises a bracket cover 8. The bracket cover 8 is located in the silica gel sleeve 7, and the lower end cover is arranged at the upper end opening of the bracket 4, and the upper end is in abutment with the air guide pipe 2. The bracket cover 8 is provided with a third air hole (not shown) in the axial direction. One end of the third air hole is in communication with the atomization cavity c, and the other end is in communication with the air guide pipe 2, so that the atomization cavity c is in communication with the air guide pipe 2.

[0046] Please refer to Figure 1 and Figure 2 , the upper end of the base 6 is provided with a protrusion for supporting the bracket 4. The air inlet channel is specifically two first air holes (not shown) provided on the base 6 in the axial direction, corresponding to the two atomization cavities c. The base 6 is further provided with a sealing ring 9 for enhancing the sealing effect between the inside of the metal felt atomizer and the outside.

[0047] As shown by the arrow in Figure 1 , when the user inhales the aerosol, the external gas enters the metal felt atomizer from the first air hole on the base 6, then enters the atomization cavity c through the second air hole f on the bracket 4, and finally reaches the smoking port a through the third air hole on the cover of the bracket 4.

[0048] In order to absorb and filter excess condensate, please refer to Figure 1 and Figure 2 , the metal felt atomizer further comprises an oil absorption member 10 arranged in the base 6. Specifically, in this embodiment, the oil absorption member 10 is a porous metal, more specifically, the oil absorption member 10 is a metal felt.

[0049] As a preferred scheme, as shown in Figure 1 and Figure 4 , the metal felt atomizer further comprises a silica gel sheet 11. The silica gel sheet 11 is arranged in the bracket 4 for accommodating the metal felt heating body 3. Specifically, in this embodiment, the silica gel sheet 11 is composed of two [shaped silica gel sheet 11 bodies, which are arranged outside the metal felt heating body 3 by flexible tight fitting, and play a protective and positioning role for the metal felt heating body 3.

[0050] The present embodiment also provides a metal felt atomization device, comprising: a metal felt atomizer as described above, and a battery rod.

[0051] The working principle of the present application is roughly as follows: the metal felt heating body 3 has one atomizing cavity c on each side of the metal felt heating body 3, the two side surfaces of the metal felt heating body 3 can adsorb liquid matrix, and can also heat and atomize, in addition, since the metal felt heating body 3 is vertically placed, the contact area of the metal felt heating body 3 with the liquid matrix and air in the atomizing cavity c is increased, thereby greatly improving the atomization efficiency of the metal felt atomizer.

[0052] The above is only used to illustrate the technical solutions of the present application but not limit, other modifications or equivalent replacements of the technical solutions of the present application made by those skilled in the art should be covered in the scope of claims of the present application as long as they do not depart from the spirit and range of the technical solutions of the present application.
