Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Art

[0002] Electronic atomizers, also known as e-cigarettes, heat and vaporize an atomizing medium to generate an aerosol for the user to inhale, simulating the sensation of smoking. As a cigarette alternative, they are popular among smokers. Currently, some electronic atomizers on the market feature a replaceable cartridge structure, meaning the atomizer unit and power supply unit are detachably connected, with the contact electrodes on the atomizer unit abutting against the spring pins of the power supply unit to achieve electrical continuity between the two. When the atomizer medium in the atomizer unit is depleted, simply replace the atomizer unit and reconnect it to the power supply unit, ensuring electrical continuity.

[0003] However, although the atomizer unit and the power supply unit are detachably connected, making the atomizer unit easy to replace, when replacing the atomizer unit in existing cartridge-replaceable electronic atomizer devices, because the contact electrodes and the spring needle need to abut each other with positive electrodes and negative electrodes with negative electrodes to ensure circuit conduction, if the user accidentally connects the atomizer unit and the power supply unit in opposite directions (i.e., the positive electrode of the contact electrode abuts the negative electrode of the spring needle, and the negative electrode of the contact electrode abuts the positive electrode of the spring needle), the electronic atomizer device will not work properly or will cause a short circuit. Therefore, it causes great inconvenience to the user when using the electronic atomizer device and also poses certain safety risks. Utility Model Content

[0035] An embodiment of the present application provides an electronic atomization device, which is used to heat an atomization medium stored inside the device to form an aerosol for inhalation by a user.

[0036] The following describes the structure of the electronic atomization device in this application, taking an electronic cigarette as an example. This embodiment is merely an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomization device of this application is not limited to an electronic cigarette, but can also be any other electronic atomization device that can atomize an atomizing medium into an aerosol, without limitation here.

[0037] See Figures 1 to 3 , Figure 1 A schematic diagram showing a partial structure of an electronic atomization device 10 in one embodiment of the present application is shown. Figure 2 shows an exploded schematic diagram of the electronic atomization device 10, Figure 3A side view of the electronic atomization device 10 is shown. The electronic atomization device 10 provided in one embodiment of the present application includes an atomization unit 100 and a power supply unit 200, wherein the atomization unit 100 and the power supply unit 200 are detachably connected to each other and electrically connected to each other. The atomization unit 100 is used to heat the atomization medium stored therein, so that the atomization medium can be atomized to generate an aerosol for the user to inhale; the power supply unit 200 is used to provide electrical energy to the atomization unit 100, so that the atomization unit 100 can generate heat for heating the atomization medium.

[0038] Specifically, the atomization unit 100 includes an oil storage cup, a vent tube, and an atomization core. The oil storage cup is used to store the atomization medium, the atomization core is used to heat and atomize the atomization medium flowing into itself, and the vent tube is used for the aerosol generated by the atomization of the atomization medium to pass through and be inhaled into the user's mouth. A power supply component is provided in the power supply unit 200, and the power supply component includes a battery and a circuit board 210 connected to the battery, wherein the battery is used to power the atomization core, and the circuit board 210 is used to control the logic on and off of the circuit, so as to further control the battery to power the atomization core or stop powering the atomization core. The specific structures of the above atomization unit 100 and the power supply unit 200 can refer to the existing technology and will not be repeated here.

[0039] Regarding the specific connection structure between the atomizing unit 100 and the power supply unit 200, the atomizing unit 100 and the power supply unit 200 may be connected by magnetic attraction, snap connection, etc. Figure 4 ,exist Figure 4 In the embodiment shown in FIG, the atomization unit 100 and the power supply unit 200 are connected by magnetic attraction. Specifically, a first magnet 110 is provided on the side of the atomization unit 100 close to the power supply unit 200, and a second magnet 220 is provided on the side of the power supply unit 200 close to the atomization unit 100. The atomization unit 100 and the power supply unit 200 are mutually attracted and connected via the first magnet 110 and the second magnet 220.

[0040] Furthermore, to achieve electrical continuity between the power supply unit 200 and the atomizer unit 100, a contact electrode 120 is provided on the outer wall of the atomizer unit 100, and a spring pin 230 is provided on the outer wall of the power supply unit 200. The contact electrode 120 is electrically connected to the atomizer core, and the spring pin 230 is electrically connected to the circuit board 210. The contact electrode 120 and the spring pin 230 abut against each other, so that the atomizer core can be electrically connected to the circuit board 210, thereby electrically connecting the atomizer unit 100 and the power supply unit 200. In this way, the circuit board 210 can control the battery to power the atomizer core.

[0041] See also Figure 1 and Figure 4In one embodiment, the spring pin 230 is provided on the side wall of the power supply unit 200 along the horizontal direction in the figure, and the contact electrode 120 is provided on the side wall of the atomization unit 100 close to the power supply unit 200; one end of the atomization unit 100 has a suction nozzle 101, and the suction nozzle 101 is provided with an air outlet 102 connected to the ventilation tube, and the opening direction of the air outlet 102 is in the vertical direction in the figure. In the vertical direction in the figure, the upward direction is defined as the first orientation, and the downward direction is defined as the second orientation, and the first orientation is opposite to the second orientation. It can be seen from this that in this embodiment, the structure of the electronic atomization device 10 is a structure in which the atomization unit 100 and the power supply unit 200 cooperate with each other on the side. Of course, it can be understood that the electronic atomization device 10 provided in this application is not limited to a structure in which the atomization unit 100 and the power supply unit 200 cooperate with each other on the side in the horizontal direction, but can also be a structure in which the atomization unit 100 cooperates with the power supply unit 200 on the top and the power supply unit 200 on the bottom, that is, the structure in which the atomization unit 100 is on the top and the power supply unit 200 is on the bottom, which is not limited here.

[0042] Preferably, in order to strengthen the mutual fixation of the atomizing unit 100 and the power supply unit 200 and prevent the atomizing unit 100 and the power supply unit 200 from still generating relative displacement and falling off from each other after being attracted to each other by the magnet, Figure 2 As shown, a groove 201 is provided on the outer wall of the power supply unit 200 close to the atomization unit 100, and a spring pin 230 is arranged on the bottom wall of the groove 201. In this way, when the power supply unit 200 and the atomization unit 100 are connected to each other, the atomization unit 100 is partially accommodated in the groove 201, and the outer wall of the atomization unit 100 is in contact with the edges around the opening of the groove 201. Therefore, due to the obstruction of the edges around the opening of the groove 201, the atomization unit 100 can be partially confined in the groove 201 without generating relative displacement between the power supply unit 200, thereby preventing the atomization unit 100 and the power supply unit 200 from separating from each other.

[0043] In other embodiments, a groove 201 may be formed on the outer wall of the atomizing unit 100, the contact electrode 120 may be disposed on the bottom wall of the groove 201, and the power supply unit 200 may be partially accommodated in the groove 201. This can also achieve the technical effect of preventing the atomizing unit 100 and the power supply unit 200 from being displaced relative to each other and falling off after being attracted to each other by the magnet. There is no particular limitation here.

[0044] Furthermore, as described in the background art, although the atomizer unit 100 and the power supply unit 200 are detachably connected, making the atomizer unit 100 easy to replace, when replacing the atomizer unit 100 in the existing cartridge-replaceable electronic atomizer device 10, since the contact electrodes 120 and the spring pins 230 need to be in positive contact with each other and the negative contact with each other to ensure circuit conduction, if the user accidentally connects the atomizer unit 100 and the power supply unit 200 in opposite directions (i.e., the positive electrode of the contact electrode 120 is in contact with the negative electrode of the spring pin 230 and the negative electrode of the contact electrode 120 is in contact with the positive electrode of the spring pin 230), the electronic atomizer device 10 will not work properly or a short circuit will occur. Therefore, it causes great inconvenience to the user when using the electronic atomizer device 10, and also poses certain safety hazards.

[0045] In order to solve this problem, the applicant of this application has considered that the contact electrode 120 or the spring pin 230 can be set to a symmetrical structure. Figure 2 and Figure 3 The outer wall of the atomizing unit 100 is provided with a pair of contact electrodes 120, and the outer wall of the power supply unit 200 is provided with a pair of elastic pins 230. One of the contact electrodes 120 in each pair is a positive electrode and the other is a negative electrode. One of the elastic pins 230 in each pair is also a positive electrode and the other is a negative electrode. A contact electrode 120 representing a positive electrode is used to abut against an elastic pin 230 representing a positive electrode, and a contact electrode 120 representing a negative electrode is used to abut against an elastic pin 230 representing a negative electrode. In the embodiment shown in the figure, there are two pairs of contact electrodes 120, combined with Figure 4 and Figure 5 As shown, the two pairs of contact electrodes 120 are arranged with a symmetry plane 50 ( Figure 4 The distance between the contact electrode 120 and the symmetry plane 50 is equal to the distance between the spring pins 230 and the symmetry plane 50.

[0046] In this way, regardless of whether the atomizer unit 100 is connected to the power supply unit 200 in the first orientation or the second orientation (i.e., regardless of whether the opening of the air outlet 102 is facing upward or downward), each spring pin 230 in the pair of spring pins 230 can abut against the corresponding contact electrode 120. That is, regardless of whether the atomizer unit 100 is connected to the power supply unit 200 in the first orientation or the second orientation, the atomizer unit 100 and the power supply unit 200 can be electrically connected to each other.

[0047] It is not difficult to understand that in another embodiment, the paired spring pins 230 can be set as two pairs, and the paired contact electrodes 120 can be set as a pair. When the atomization unit 100 is connected to the power supply unit 200 in the first orientation or the second orientation, the atomization unit 100 and the power supply unit 200 can also be electrically connected to each other.

[0048] Correspondingly, when the atomization unit 100 and the power supply unit 200 are magnetically connected, in order to ensure a more secure adsorption, the first magnet 110 or the second magnet 220 also has at least two groups, each first magnet group includes at least one first magnet 110, and each second magnet group includes at least one second magnet 220. When there are two groups of first magnets 110, the two groups of first magnets 110 are symmetrically arranged about the symmetry plane 50; when there are two groups of second magnets 220, the two groups of second magnets 220 are symmetrically arranged about the symmetry plane 50. This allows the atomization unit 100 and the power supply unit 200 to be adsorbed to each other at least two locations, thereby ensuring that the atomization unit 100 and the power supply unit 200 can be more securely connected and will not detach.

[0049] In addition, further, if Figure 4 As shown, the electronic atomization device 10 also includes an airflow sensor 300. A mounting position 11 connected to the external environment is provided in the power supply unit 200, and the airflow sensor 300 is arranged in the mounting position 11. Exemplarily, the mounting position 11 is arranged between two pairs of contact electrodes 120. Furthermore, the distance from the mounting position 11 to one pair of contact electrodes 120 is equal to the distance to the other pair of contact electrodes 120; or, when two pairs of elastic needles 230 are provided, the distance from the mounting position 11 to one pair of elastic needles 230 is equal to the distance to the other pair of elastic needles 230. When the user uses the electronic atomization device 10 to inhale, the airflow sensor 300 can sense the negative pressure generated by the airflow and trigger the atomization core to work, so that the atomization core can heat the atomization medium flowing into itself.

[0050] Specifically, in this embodiment, in order to connect the mounting position 11 to the external environment, an air inlet 202 is provided on the outer wall of the power supply unit 200, and an air through hole 203 connected to the air inlet 202 is provided on the side of the power supply unit 200 close to the atomizer unit 100, and an air vent 103 connected to the air outlet 102 is provided on the side of the atomizer unit 100 close to the power supply unit 200, so that the air inlet 202, the mounting position 11, the air through hole 203, the air vent 103 and the air outlet 102 are connected to each other. Therefore, when the user inhales, the air flow can pass through the air inlet 202, the mounting position 11, the air through hole 203, the air vent 103 and the air outlet 102 to form a negative pressure, so that the airflow sensor 300 can be triggered to control the battery to power the atomizer core.

[0051] Furthermore, since the atomizing unit 100 and the power supply unit 200 are two independent components, there is a gap between the two at the position where they are connected. When the air flows from the air hole 203 to the vent hole 103, in order to prevent the air flow from flowing away from the above gap and causing air flow loss, the mounting position 11 is opened along the power supply unit 200. Figure 4 The middle position in the vertical direction (i.e. the position where the symmetry plane 50 passes), and combined with Figure 4 、 Figure 5 and Figure 6 As shown, a sealing member 400 is further provided in the mounting position 11. A mounting groove 401 is provided on one side of the sealing member 400. The air flow sensor 300 is disposed in the mounting groove 401. The air hole 203 is provided on the sealing member 400. The side of the sealing member 400 facing away from the mounting groove 401 has an annular sealing rib 403. The sealing rib 403 is formed with a sealing groove 402 that passes through the mounting groove 401 of the air hole 203. The sealing rib 403 abuts against the atomizing unit 100 and surrounds the air hole 103. In this way, regardless of whether the atomizing unit 100 is connected to the power supply unit 200 in the first orientation or the second orientation, the sealing rib 403 can surround the air hole 103 to achieve air sealing, thereby ensuring that the air flow does not flow away from the gap formed between the atomizing unit 100 and the power supply unit 200, thereby ensuring that the air flow sensor 300 can always sensitively sense the negative pressure generated by the air flow.

[0052] It is worth noting that for the electronic atomization device 10 provided in the present application, the opening position of the installation position 11 and the opening position of the air inlet 202 are not limited to the structure shown in the embodiment of the figure. In other embodiments, there may be multiple combinations of structures. For example, when the installation position 11 is opened in the power supply unit 200, the air inlet 202 can also be opened on the outer wall of the atomization unit 100; or the installation position 11 can be opened in the atomization unit 100. At this time, the air inlet 202 can be opened on the outer wall of the atomization unit 100 or on the outer wall of the power supply unit 200.

[0053] Specifically, when the mounting position 11 is opened in the power supply unit 200 and the air inlet 202 is opened on the outer wall of the atomizer unit 100, the air hole 203 is still opened on the side of the power supply unit 200 close to the atomizer unit 100, and the air vent 103 is still opened on the side of the atomizer unit 100 close to the power supply unit 200. The mounting position 11 can still be connected to the external environment, and the air flow sensor 300 can also sense the negative pressure generated by the airflow during inhalation.

[0054] When the mounting position 11 is opened in the atomization unit 100 and the air inlet 202 is opened on the outer wall of the power supply unit 200, the air hole 203 opened on one side of the power supply unit 200, the seal 400 in the power supply unit 200 and the air vent 103 opened on one side of the atomization unit 100 are still retained; when the air inlet 202 is opened on the outer wall of the atomization unit 100, the power supply unit 200 does not need to open the air hole 203, the atomization unit 100 does not need to open the air vent 103, and the air inlet 202 and the air outlet 102 can both be connected to the mounting position 11.

[0055] It should be noted that regardless of whether the air inlet 202 is located on the outer wall of the power supply unit 200 or the outer wall of the atomizer unit 100, if the airflow sensor 300 is disposed within the atomizer unit 100, the airflow sensor 300 can be connected to the contact electrode 120 via a wire, so that after the contact electrode 120 abuts the spring pin 230, the airflow sensor 300 is electrically connected to the circuit board 210 of the power supply assembly. This can also achieve the same function as the structure of the aforementioned embodiment, that is, when the airflow sensor 300 senses the negative pressure generated by the airflow, the airflow sensor 300 can also trigger the circuit board 210 to control the battery to power the atomizer core.

[0056] It can be seen that the electronic atomization device 10 provided in the present application can have a variety of deformed structures. In the above multiple deformed structures, no matter when the atomization unit 100 is connected to the power supply unit 200 in the first orientation or when it is connected to the power supply unit 200 in the second orientation, normal suction of the electronic atomization device 10 can be guaranteed, which solves the problem that the electronic atomization device 10 cannot work normally or short-circuits when the atomization unit 100 and the power supply unit 200 are installed reversely, facilitates user use, and greatly improves the consumer's experience.

[0057] Finally, it should be noted that the various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above-described 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.

[0058] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
