Description
Technical Field
[0001] This application relates to the technical field of atomization, and in particular to an atomizer and an electronic atomization device. Background Art
[0002] An electronic atomization device, also known as an electronic cigarette, is a device that heats and atomizes an atomization medium to generate an aerosol for users to inhale to simulate the feeling of smoking. As a substitute for cigarettes, it is deeply loved by smokers. A traditional electronic atomization device consists of an atomizer and a power supply unit. The interior of the atomizer has an oil storage cavity, and the atomization medium is stored in the oil storage cavity. The power supply unit supplies power to the atomizer so that the atomizer can heat and evaporate the atomization medium in the oil storage cavity to generate an aerosol for users to inhale.
[0003] Existing electronic atomization devices usually use contact electrodes to be welded to input wires so that the atomization core is electrically connected to the power supply unit through the contact electrodes, thereby realizing the conduction of the circuit. However, when using a soldering iron tip to weld the input wire to the contact electrode, the temperature of the soldering iron tip is usually as high as 360°C. The high temperature is easily conducted from the contact electrode to the heating base where the contact electrode is installed, resulting in the plastic heating base being extremely easy to melt at high temperatures. If you want to ensure that the heating base does not melt, you need to control the welding time of the soldering iron tip. Through experiments, it is proved that the welding duration of the soldering iron tip needs to be controlled within about 1 second to 1.5 seconds to ensure that the heating base does not melt. However, this poses a certain difficulty for the welding operation of the operator, resulting in easy occurrence of welding defects such as false soldering, virtual soldering, or missed soldering, thus easily causing poor contact between the power supply unit and the atomizer, and further resulting in the inability of users to suck when using the electronic atomization device. At the same time, there is also a hidden danger of atomization medium leakage when the electronic atomization device product is shipped. Summary of the Utility Model

[0013] In one embodiment, a support component connected to the heating base is provided inside the housing body.

[0014] In one embodiment, a connecting column is further provided inside the housing body.

In this way, due to the existence of the adapter board, the soldering iron head can be completely non-contact with the electrode during soldering, thus avoiding the direct conduction of the high temperature generated by the soldering iron head to the electrode, so that the electrode will not have too high a temperature, and further it can be conducted while preventing the heating base on the housing from melting. And since the input wire is not directly welded to the electrode, there is no need to deliberately control the soldering time too short, thus avoiding problems such as false soldering, virtual soldering or missed soldering, and further avoiding the phenomenon that the user cannot suck when using the electronic atomization device.

[0032] An embodiment of the present application provides an atomizer and an electronic atomization device. The electronic atomization device includes an atomizer and a power supply unit. The power supply unit is electrically connected to the atomizer and is used to supply electrical energy to the atomizer. The atomizer is used to heat the atomization medium stored inside itself when powered on to form an aerosol for the user to inhale.
[0033] Next, taking the electronic atomization device as an electronic cigarette as an example, the structures of the electronic atomization device and the atomizer in this application will be described. This embodiment is only used as an example for illustration and will not limit the technical scope of this application. It can be understood that in other embodiments, the electronic atomization device of this application is not limited to being an electronic cigarette and can also be any other electronic atomization device that can atomize the atomization medium into an aerosol, which is not limited here.
[0034] Refer to Figure 1 and Figure 2 , Figure 1The figure shows a schematic external view of the atomizer 10 in an electronic atomization device according to an embodiment of the present application. Figure 2 The figure shows a cross-sectional view of the internal structure of the above atomizer 10. The atomizer 10 provided by an embodiment of the present application includes a housing 100, an atomization core 200, and a conduction component 300. The housing 100 has an oil storage cavity 101 for accommodating an atomization medium; the atomization core 200 is arranged in the housing 100 and is used for heating and atomizing the atomization medium flowing from the oil storage cavity 101 into the atomization core 200 to generate an aerosol for the user to inhale; the conduction component 300 is arranged between the atomization core 200 and a power supply unit (not shown in the figure), and is used to electrically connect the atomization core 200 and the power supply unit to achieve electrical conduction between the atomization core 200 and the power supply unit, so that the power supply unit can supply power to the atomization core 200.
[0035] Specifically, as Figure 3 and Figure 4 shown, the conduction component 300 includes a transfer board 310 and electrodes 320. The transfer board 310 is arranged on the housing 100. One end of the electrode 320 is connected to the atomization core 200, and the other end is connected to the transfer board 310. The transfer board 310 is provided with solder joints 330 for connecting with the input wire 60, so that the atomization core 200 is electrically connected to the power supply unit through the conduction component 300.
[0036] In Figure 3 and Figure 4 the embodiments shown, there are two electrodes 320. One of the electrodes 320 is a positive electrode 320, and the other electrode 320 is a negative electrode 320. Correspondingly, there are also two solder joints 330. One of the solder joints 330 is used for welding with the input wire 60 representing the positive pole, and the other solder joint 330 is used for welding with the input wire 60 representing the negative pole. Of course, the number of electrodes 320 is not limited, and it can also be three or four.
[0037] More specifically, referring to Figure 1 and Figure 2 , in the structure of the housing 100, the housing 100 includes a housing body 110 and a heating base 120. One end of the housing body 110 has a mouthpiece 111, and the other end has an opening. The heating base 120 is detachably arranged at the end of the housing body 110 with the opening and closes the opening. The bottom wall of the heating base 120 is provided with at least two buckling positions 121 that are opposite and protrude relative to the bottom wall of the heating base 120. The end of each buckling position 121 is hook-shaped and each has a lapping surface. The transfer board 310 is lapped on the lapping surface so that the transfer board 310 is spaced from the bottom wall of the heating base 120.
[0038] Please continue to refer to Figure 4, in the connection structure between the adapter board 310 and the electrode 320, the electrode 320 includes a body 321 and a pole column 322 connected to one end of the body 321. The outer diameter of the body 321 is greater than that of the pole column 322, so that a step surrounding the pole column 322 is formed between the body 321 and the pole column 322. The body 321 passes through the heating base 120, the pole column 322 passes through the adapter board 310, and a columnar connecting member 340 is sleeved on the outer peripheral surface of the pole column 322. One end of the connecting member 340 abuts against the step, and the other end abuts against the adapter board 310.
[0039] Preferably, the connecting member 340 is an elastic element, such as a spring, etc. In the natural state, the length of the elastic element is greater than the distance between the adapter board 310 and the step of the above-mentioned electrode 320, so that one end of the elastic element can produce recoverable deformation when abutting against the above-mentioned step and the other end abuts against the adapter board 310, so that the elastic element can provide an elastic force to tightly abut the electrode 320 against the atomization core 200. In this way, it is beneficial to keep good contact between the electrode 320 and the atomization core 200, and avoid the phenomenon of poor contact between the power supply unit and the atomization core 200.
[0040] It can be understood that the connection method between the adapter board 310 and the electrode 320 is not limited to being connected through the above-mentioned connecting member 340, and the two can also be directly connected, as long as the effect of preventing the high temperature generated by the soldering iron head from directly conducting to the electrode 320 can be achieved, and it is not limited here.
[0041] During installation, first install the electrode 320 into the heating base 120 and fix it, then sleeve the connecting member 340 on the pole column 322 of the electrode 320, then pass the pole column 322 through the adapter board 310, and make the adapter board 310 lap on the buckle 121 at the bottom of the heating base 120. At this time, the connecting member 340 pre-presses the step of the body 321 of the electrode 320 and the adapter board 310 respectively, so that the adapter board 310 and the electrode 320 are connected to each other to form a conduction assembly 300. Finally, weld the input wire 60 on the solder joint 330 of the adapter board 310.
[0042] In this way, due to the presence of the adapter board 310, the operator can make the soldering iron head not contact the electrode 320 at all when holding the soldering iron head for soldering. In this way, the high temperature generated by the soldering iron head is prevented from directly conducting to the electrode 320, so that the electrode 320 will not have too high a temperature, and thus the heating base 120 on the housing 100 will not melt while achieving conduction. And because the input wire 60 is not directly welded to the electrode 320, there is no need to deliberately control the soldering time too short, so that problems such as false soldering, virtual soldering or missed soldering are avoided, and thus the phenomenon that the user cannot suck when using the electronic atomization device is avoided.
[0043] In the present application, the adapter board 310 can be an additional adapter board 310, or it can be an adapter board 310 carrying a heating circuit or a power supply circuit.
[0044] Referring to Figure 2 , in the structure within the housing 100, a support assembly 400 connected to the heating base 120 is provided within the housing body 110. The surface of the support assembly 400 facing away from the heating base 120 and the inner wall of the housing body 110 together form an oil storage cavity 101, while the surface of the support assembly 400 facing the heating base 120 and the inner wall of the heating base 120 together form an oil absorption cavity 102. An oil absorption cotton 500 is provided in the oil absorption cavity 102. The oil absorption cotton 500 is used to adsorb the condensate formed by the aerosol not inhaled by the user gradually liquefying as the temperature drops, so as to prevent the condensate from flowing onto the electrode 320 and causing a short circuit, thereby avoiding potential safety hazards.
[0045] Preferably, a part of the inner wall of the heating base 120 for forming the oil absorption cavity 102 is designed as an inclined surface. Specifically, the inclined surface extends obliquely in the direction close to the mouthpiece 111, so that after the bottom wall of the oil absorption cavity 102 deposits condensate, due to the slope formed by the inclined surface, the condensate will not flow onto the electrode 320, thus further avoiding potential safety hazards.
[0046] More preferably, as a further improvement of the above-mentioned embodiment, in order to prevent the excess condensate seeping out of the oil absorption cotton 500 from flowing randomly on the bottom wall of the oil absorption cavity 102, so as to further reduce the risk of condensate leakage. As Figure 5 shown, a plurality of oil storage grooves 122 arranged in an array are further provided on the bottom wall of the oil absorption cavity 102. The function of the oil storage grooves 122 is firstly to recover the excess condensate seeping out of the oil absorption cotton 500, so that the excess condensate seeping out is received in the oil storage grooves 122, avoiding the above-mentioned excess condensate from flowing randomly on the bottom wall of the oil absorption cavity 102. Secondly, it stores the excess condensate so that the condensate recovered in the oil storage grooves 122 can be reused.
[0047] Furthermore, a plurality of oil guiding grooves 123 are provided on the side wall of the oil absorption cavity 102 at intervals along the circumferential direction of the oil absorption cavity 102. Each oil guiding groove 123 extends along the depth direction of the oil storage groove 122. The function of the oil guiding grooves 123 is to provide a guiding effect for the condensate adsorbed on the side wall of the oil absorption cavity 102, so that the condensate adsorbed on the side wall of the oil absorption cavity 102 can be smoothly guided into the oil storage grooves 122, avoiding the condensate from flowing randomly on the side wall of the oil absorption cavity 102 or staying on the side wall of the oil absorption cavity 102 all the time.
[0048] Please continue to refer to Figure 2, in one embodiment, there is a connecting post 600 inside the shell body 110. The connecting post 600 extends from the inner wall of the end of the shell body 110 with the suction nozzle 111 towards the inside of the shell body 110 and is connected to the support assembly 400. Under the suction action of the user, in order to enable the outside air to enter the inside of the atomization core 200, mix with the aerosol generated by the atomization core 200 heating the atomization medium and then be inhaled by the user, the heating base 120 is provided with an air inlet hole 120a, the suction nozzle 111 is provided with an air outlet hole 111a, and the connecting post 600 is provided with an air passage 601 penetrating through opposite ends of itself. The air inlet hole 120a and the air outlet hole 111a are communicated with each other through the air passage 601.
[0049] In terms of the structure of the support assembly 400, an oil guiding cavity 401 communicating with the oil storage cavity 101 is provided on one side of the support assembly 400 for forming the oil storage cavity 101. Specifically, the support assembly 400 includes a bracket 420 and a sealing member 410 sleeved on the bracket 420. One side of the sealing member 410 and the inner wall of the shell body 110 together form the oil storage cavity 101. The oil guiding cavity 401 penetrates through the sealing member 410 and extends into the bracket 420. And an atomization cavity 402 is also provided in the bracket 420. The atomization core 200 is arranged in the atomization cavity 402. The atomization cavity 402 communicates with the oil guiding cavity 401, the oil absorption cavity 102 and the air passage 601 respectively.
[0050] In this way, the atomization medium in the oil storage cavity 101 can flow through the oil guiding cavity 401 to the atomization core 200 and be heated by the atomization core 200 to generate aerosol. The aerosol gathered in the atomization cavity 402 can mix with the air entering the atomization cavity 402 through the air inlet hole 120a and then enter the air passage 601 together and be inhaled into the user's mouth through the air outlet hole 111a. The condensate formed after the residual aerosol gathered in the atomization cavity 402 cools can also directly enter the oil absorption cavity 102 and be adsorbed by the oil absorption cotton 500, thus realizing the connection of the oil path and the air path.
[0051] In addition, in a preferred embodiment, when the electronic atomization device is working, in order to accelerate the flow of the atomization medium in the oil storage cavity 101 to the atomization core 200, the cavity wall of the oil guiding cavity 401 is inclined. Specifically, in the direction where the suction nozzle 111 points to the heating base 120, the cavity wall of the oil guiding cavity 401 is inclined towards the central axis of the air passage 601, so that the atomization medium can flow along the cavity wall of the oil guiding cavity 401 to the atomization core 200 under the action of gravity after entering the oil guiding cavity 401. Thus, there can be sufficient atomization medium flowing to the atomization core 200 to avoid dry burning and generating a burnt smell, and therefore the user's inhalation taste can be guaranteed.
[0052] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.
[0053] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
