An Atomizing Element Bracket and An AtomizerField of the invention
[0001] This invention relates to the field of electronic atomization, in particular to an atomizing element bracket and the electronic atomizer using the atomizing element bracket.Background Art
[0002] In the present invention, atomization refers to the atomization of liquid into an aerosol inhalable by the user through the mouth and nose. And atomization has a wide range of applications in e-cigarettes, medical auxiliary equipment such as atomization therapeutic machines, home and vehicle air quality improvement equipment, and other products.
[0003] The atomizing element functions mainly to turn electric energy into thermal energy, and heat and vaporize the atomizing liquid into aerosol. The functions of the atomizing element bracket include fixing the atomizing element, connecting the atomizing element with the atomizing liquid storage bin, connecting the vaporizer with the inlet and outlet passages, and so on.
[0004] A typical structure of the atomizer of prior art and atomizing element bracket is shown in Fig. 1. The atomizing element is installed in the bracket, and a liquid storage is set above to store the atomizing liquid. The atomizing liquid in the liquid storage enters the atomizing liquid passage in the atomizing element bracket through liquid down-flow hole a, and then reaches the atomizing element. After being vaporized by the atomizing element, the atomizing liquid mixes with the air under the atomizing element to form an aerosol, and is extracted from suction port b. The air that needs to be filled in the liquid storage enters through air filling passage c. The disadvantages of this structure are: On the one hand, the atomizing liquid passage is too long and easy to result in the poor flow of the liquid and the residue of the atomizing liquid, especially when the atomizing liquid is highly viscous, this defect becomes very obvious; The air filling passage is also too long and circuitous and easy to be blocked by bubbles and affect liquid flow. On the other hand, to ensure the smooth down-flow of the atomizing liquid, the inner diameter of the atomizing liquid passage shall not be too small, which means besides the atomizing liquid passage, it is still necessary to set the air outlet passage and air exchange passage in the atomizer, which disables the reduction of the size of the entire atomizer.
[0005] Summary of this Invention
[0006] In view of the shortcomings of the prior art, the present invention aims to provide an atomizing element bracket characterized in that it comprises air outlet, air inlet, liquid inlets, liquid guiding interface, and seal; The air outlet lies in the center of the atomizing element bracket; The liquid guiding interface is arranged around the air outlet; The liquid inlets are close to the liquid guiding interface, and the atomizing element installation bin is arranged below the liquid inlets; The air inlet is located near the atomizing element installation bin; The seal is located at the periphery of the liquid guiding interface.
[0007] Preferably, there are two symmetrical liquid inlets, one front and one back in the atomizing element bracket.
[0008] Preferably, the liquid guiding interface includes a twisted bevel, and the twisted bevel includes a high section and a low section in the atomizing element bracket;
[0009] Preferably, the lowest point of the low section is higher than or high as the bottom of liquid inlets 12, and is tilting toward the liquid inlets in the atomizing element bracket.
[0010] Preferably, the liquid guiding interface also includes a second bevel tilting from the air outlet downwards to the twisted bevel in the atomizing element bracket.
[0011] Preferably, liquid inlets are horns, that is, the opening on one side towards the liquid guiding interface is larger than the opening on the other side in the atomizing element bracket.
[0012] Preferably, the seal is made of silicone sealant matching the edge of the twisted liquid guiding interface in shape in the atomizing element bracket.
[0013] Preferably, the main part of the bracket is plastic, and the silicone sealant is made with plastic as an organic whole in the atomizing element bracket.
[0014] This invention also provides an electronic atomizer characterized in that it comprises air outlet passage, shell, and any of the atomizing element bracket mentioned above; The lower end of the air outlet passage is connected with the air outlet of the atomizing element bracket; A seal is formed between the seal and the inner wall of the shell; A liquid storage is formed among the outer wall of the outlet passage, the liquid guiding interface, and the inner wall of the shell.
[0015] Preferably, the electronic atomizer is used to atomize highly viscous atomizing liquid.
[0016] The electronic atomizer and atomizing element bracket of the invention calls off the design of atomizing liquid passage and air filling passage in the prior art, not only smoothing liquid down-flow, but also making the entire atomizer smaller and exquisite.

[0024] Embodiments
[0025] The execution of this invention is explained by specific embodiments below, and a person in this art can easily understand other advantages and effects of this invention from the details disclosed herein. The invention can also be implemented or applied in other different ways, and the details herein can also be modified or changed in various ways based on different views and applications without deviating from the spirit of this invention.
[0026] Please refer to the attached drawings then. To be sure, the drawings provided in this embodiment are only explaining the basic conception of this invention, and thus do not show the actual number, size and shape of the component put into practice but only showing the component associated with the invention; The type, number and proportion of the components actually put into practice can be a random change, and the component layout pattern may also be more complex. Unless otherwise specified, the words “up” , “down” , “left” , and “right” used herein are all from the perspective of the observer in the attached drawing.
[0027] First, refer to Fig. 2, which schematically shows the main structure of the atomizer of this invention (excluding the suction nozzle) . To clearly show the internal structure, the shell of the liquid storage is represented by a dashed line in Fig. 2. Mark 1 stands for the atomizing element bracket of the invention, mark 2 represents the air outlet passage, and space 3 between the outer wall of air outlet passage 2 and the shell is the liquid storage. The atomizing liquid in liquid storage 3 directly enters liquid inlets 12 through liquid guiding interface 13 and reaches atomizing element 16 below (see Fig. 6) . As can be seen from Fig. 2, the main difference between the atomizer of this invention and the atomizer of prior art is that liquid guiding interface 13 on atomizing element bracket 1 is directly used as the bottom of liquid storage 3, and is closely adjacent to liquid inlets 12 of atomizing element 16 (namely, directly connected) ; The atomizing liquid passage between the liquid down-flow hole under the liquid storage and the atomizing element is completely removed. Compared with the prior art, this greatly remedies the defect of poor liquid down-flow; When highly viscous atomizing liquid is used (the viscosity is greater than 10,000 cps at room temperature 25℃) , the advantages of this invention are more obvious. On the other hand, the limitation of the atomizing liquid passage diameter on the size of the atomizer is evaded so that the entire atomizer can be smaller and exquisite.
[0028] In the following, the specific structure of the atomizing element bracket of the invention is introduced in combination with figures 3 to 5. Fig. 3 is a stereogram about the embodiment of the invention, and Fig. 4 is a front view of the embodiment. Atomizing element bracket 1 comprises air outlet 11, which is centrally located; Liquid guiding interface 13 around outlet 11; Seal 14 at the periphery of liquid guiding interface 13; And two symmetrical (one front and the other back) liquid inlets 12 adjacent to liquid guiding interface 13.
[0029] Liquid guiding interface 13 comprises a twisted bevel which is divided into two sections, high section 133 (see figures 3 and 4) at the high point, and low section 132 (see figures 3 and 5) near liquid inlets 12. The lowest point of low section 132 is connected to the bottom of liquid inlets 12 and tilting toward the liquid inlets (see Fig. 5) . Liquid guiding interface 13 is designed as two bevels with height difference so that when the atomizing liquid is depleted in liquid storage 3, it can be converged along liquid guiding interface 13 to low section 132 and enter liquid inlets 12, so as to avoid or reduce atomizing liquid residue on liquid guiding interface 13. To further reduce aerosol residue, liquid guiding interface 13 also includes bevel 131 that is tilting downward to the shell of the liquid storage against air outlet 11. Installation bin 15 below liquid inlets 12 is used to install atomizing element assembly 16.
[0030] Because liquid inlets 12 are located at the bottom of liquid storage 3, and are as close to atomizing element assembly 16 as possible, the atomizing liquid near liquid inlets 12 is easy to be preheated by atomizing element assembly 16 at work. Therefore, this design is especially suitable for highly viscous atomizing liquid.
[0031] The working principle of the atomizer of this invention is described in combination with Fig. 6 below, a sectional view of the embodiment in Fig. 4 along line A-A. To simplify the explanation, Fig. 6 only shows the core atomizing element and the atomizing element bracket, but not the liquid storage, air outlet passage and other structures. Arrow A in Fig. 6 represents the main air course. When negative pressure is exerted to the suction nozzle of the atomizer in use, air would flow up from air inlet 17 under the atomizer along arrow A, and flow to the outlet passage through the air course on both sides of atomizing element bracket 1 and air outlet 11. However, the atomizing liquid is heated and vaporized by atomizing element 16, and the vaporized atomizing liquid enters main air course A along arrow B to form an aerosol. In addition, due to the reduction of atomizing liquid in liquid storage 3, a small amount of air would be supplied into liquid storage 3 from liquid inlets 12.
[0032] The air supplied into liquid storage 3 would form bubbles. To prevent the bubbles from interfering the liquid flow, two liquid inlets 12 are set in the preferred embodiment, so that the other can remain normal for liquid flow even if one liquid inlet 12 if blocked by bubble. And more preferably, liquid inlets 12 are designed as horn-shape: the opening on one side towards the liquid guiding interface is larger than the opening on the side towards the atomizing element, as shown in Fig. 4; the upper contour of the opening towards liquid guiding interface 13 is 121, and the upper contour of the opening towards the other side is 122. Bubbles usually gather at the top of liquid inlets 12 and prevent the atomizing liquid from entering into liquid inlets 12 directly from the top. At this time, the atomizing liquid can still enter liquid inlets through the twisted liquid guiding interfaces on both sides of liquid inlets 12. Even if there are bubbles blocking the inlet, they can be removed by slight disturbance to restore the clearance of liquid inlets 12.
[0033] The above embodiments are illustrative only of the principle and effectiveness of the invention and are not intended to limit the invention. Any person who is familiar with the technique may modify or alter the above embodiments without prejudice to the spirit and scope of the invention. For example, there are two symmetrical liquid inlets 12, one front and the other back to further prevent bubbles from blocking the liquid inlets and ensure the smooth flow of the liquid, and this shall not constitute a limitation of the present invention. When liquid inlet 12 is designed to be large enough, or in some inferior embodiments, only one liquid inlet can be designed; In addition, liquid guiding interface 13 in this preferred embodiment is divided into two parts, and the second part is provided with a twisted bevel comprising a high section and a low section to facilitate liquid flow and reduce residual fluid. Therefore, all equivalent modifications or changes made by those with common sense in the technical field to which the invention belongs without prejudice to the spirit and technical ideas revealed by the invention shall still be covered by the claims of the invention.
