Description

Technical Field

[0001] The utility model relates to the technical field of atomization devices, and in particular to a power supply housing, a battery assembly, and an electronic atomization device. Background Art

[0002] See also Figure 1 The battery assembly 100 for supplying power to the atomizer 200 comprises:

[0003] A battery shell 101, wherein a pin hole 1012 is provided on the top of the battery shell 101;

[0004] The power supply probe 102 has an upper portion protruding from the top of the battery shell 101 so as to be electrically connected to the atomizer 200, a middle portion of the power supply probe 102 passes through the pin hole 1012 and is interference fit with the pin hole 1012 to complete fixation, and a lower portion of the power supply probe 102 extends into the interior of the battery shell 101 so as to be welded to a wire.

[0005] In actual production, it is found that after the power supply probe 102 passes through the pin hole 1012, the power supply probe 102 fits tightly with the battery shell 101. At this time, welding the wire to the power supply probe 102 will cause the power supply probe 102 to heat up. The power supply probe 102 transfers the heat to the battery shell 101, which will cause the hole wall of the pin hole 1012 to deform, thereby increasing the gap between the power supply probe 102 and the hole wall of the pin hole 1012 and reducing the sealing performance. Foreign matter such as water, gasoline, and dirt from the outside will enter the battery shell 101 through the gap between the power supply probe 102 and the hole wall of the pin hole 1012, damaging other electronic devices.

[0006] Therefore, it is necessary to improve the existing battery assembly to solve the problem that welding the power supply probe may cause the sealing performance between the battery shell and the power supply probe to decrease.

[0007] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.

[0055] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0056] The utility model provides a power supply shell, a battery assembly, and an electronic atomization device, which are suitable for application scenarios in which an aerosol matrix is ​​atomized into an aerosol, and can effectively solve the problem that welding operations on the power supply probe will lead to a decrease in the sealing performance between the battery shell and the power supply probe.

[0057] Specifically, the electronic atomization device provided by the utility model can be applied to the following fields:

[0058] Electronic atomizers can be used as medical atomizers in the medical field, especially for respiratory diseases. Through electronic atomizers, drugs can be dispersed into tiny droplets or particles and directly enter the respiratory tract and lungs to humidify the airways and treat respiratory inflammation. This method allows drugs to act directly on the affected area without going through the blood circulation, so the effect is fast and significant;

[0059] Electronic atomizers can be used as beauty instruments in the beauty industry. Electronic atomizers use atomization technology to spray liquid water in the form of atomized water, so that the water can quickly pass through the skin pores into the basal layer of the skin, allowing the skin to directly absorb most of the sprayed water to achieve the effect of hydrating and moisturizing.

[0060] Electronic atomizers can be used as humidifiers in the field of household appliances. In winter in the north, due to the dry air caused by heating, electronic atomizers have become important household items to increase indoor humidity and improve living comfort.

[0061] Alternatively, the electronic atomizer device can also be used as an electronic cigarette atomizer in the consumer market, which produces mist particles by heating the e-liquid, imitating the smoke effect after the traditional tobacco is burned.

[0062] It is worth noting that the electronic atomization device in the present invention is not limited to the specific applications mentioned above. The specific applications mentioned above are only some examples of the many uses of the electronic atomization device of the present invention and do not constitute a specific limitation on the scope of protection.

[0063] The power supply housing, battery assembly, and electronic atomization device provided by the present invention are introduced below in conjunction with specific drawings.

[0064] See also Figure 2 The electronic atomization device provided in this embodiment includes an atomizer 200 for atomizing an aerosol matrix into an aerosol, and a battery assembly 100 for supplying power to the atomizer 200 .

[0065] In this embodiment, the structure of the atomizer 200 can be the same as that of the existing atomizer, for example, it can include an atomizer housing provided with a liquid storage chamber and an aerosol outlet, a liquid storage cotton located in the liquid storage chamber and used to absorb and store the aerosol matrix, an atomizer core bracket located in the atomizer housing, an atomizer core assembly mounted on the atomizer core bracket, and an electrode sheet 200a fixed to the bottom surface of the atomizer housing and electrically connected to the atomizer core assembly, etc. It is worth pointing out that the specific structure of the atomizer 200 is not the focus of the present utility model, and does not limit the function and structure of the battery assembly 100, so it will not be described in detail.

[0066] See also Figure 3 and Figure 4 The battery assembly includes a power supply housing 1 and a battery cell 2 located in the power supply housing 1. As an optional embodiment, the battery cell 2 is a storage battery. Further, the power supply housing 1 is provided with a charging interface for charging the battery cell 2. In this embodiment, the charging interface can be a Micro USB interface, a USB Type-C interface, or a Lightning interface, etc., which is not limited in this embodiment.

[0067] The power supply housing 1 includes a battery case 101 , a power supply probe 102 , and a sealing member 103 .

[0068] The battery shell 101 is provided with a battery compartment 1011 for accommodating the battery core 2 and a pin hole 1012 connecting the battery compartment 1011 to the external space of the battery shell 101. The upper part of the power supply probe 102 protrudes upward to the outside of the battery shell 101 so as to be in conductive contact with the electrode sheet 200a at the bottom of the atomizer, the middle part passes through the pin hole 1012, and the lower part extends into the battery compartment 1011 and is electrically connected to the battery core 2 through a wire or the like.

[0069] As an optional embodiment, the pin hole 1012 is a stepped hole, specifically including an upper hole 1012a with a larger diameter and a lower hole 1012b with a smaller diameter. Correspondingly, the power supply probe 102 includes an upper protrusion 1021, a stopper 1022, and a lower protrusion 1023 from top to bottom; wherein the stopper 1022 is located in the upper hole 1012a, and the lower protrusion 1023 passes through the lower hole 1012b, and further, the diameter of the stopper 1022 is larger than the diameter of the lower hole 1012b, so as to prevent the stopper 1022 from passing downward through the lower hole 1012b. During assembly, the lower protrusion 1023 is inserted into the lower hole 1012b from top to bottom until the limiting piece 1022 completely enters the upper hole 1012a. At this time, the upper protrusion 1021 protrudes upward to conductively contact the electrode sheet 200a at the bottom of the atomizer 200.

[0070] The sealing member 103 is sleeved on the power supply probe 102 and is respectively in contact with the power supply probe 102 and the battery shell 101. Even if the power supply probe 102 is heated by welding and the hole wall of the pin hole 1012 is deformed, and the gap between the deformed hole wall and the power supply probe 102 is enlarged, the sealing member 103 can prevent foreign matter such as water, gasoline, and dirt outside the battery shell 101 from entering the battery compartment 1011 through the gap between the sealing member 103 and the power supply probe 102 and / or through the gap between the sealing member 103 and the battery shell 101, thereby protecting other electronic devices in the battery compartment 1011 from damage.

[0071] In this embodiment, there are two power supply probes 102 (one of which is the positive pole and the other is the negative pole), and each power supply probe 102 is correspondingly provided with a sealing member 103. The sealing member 103 is provided with a needle hole 1031 for the power supply probe 102 to pass through. The hole wall of the needle hole 1031 is in contact with the power supply probe 102, thereby preventing foreign matter from penetrating inward through the gap between the sealing member 103 and the power supply probe 102.

[0072] Furthermore, the hole wall of the needle hole 1031 is provided with an inner sealing convex rib 1032 protruding toward the power supply probe 102. The inner sealing convex rib 1032 can be tightly fitted on the power supply probe 102 to improve the sealing performance between the power supply probe 102 and the sealing member 103.

[0073] In this embodiment, see Figure 5 The two seals 103 are an integral structure connected as a whole, that is, the two seals 103 are combined to form an "8"-shaped structure, which can be made by an integrated injection molding process. When assembling the power supply housing 1, only one installation operation of the seal 103 is required, which is beneficial to improving production efficiency.

[0074] Of course, in some other embodiments, the two seals 103 may also be independent structures separated from each other, that is, each seal 103 is a separate annular structure. The annular seal 103 is a standard part, easy to purchase, and inexpensive. The utility model does not limit the connection form of the two seals 103.

[0075] In this embodiment, the seal 103 is a non-metallic seal to avoid short circuit caused by conductive connection with the power supply probe 102. As an optional implementation, the seal 103 can be an asbestos gasket, a non-asbestos gasket, a paper gasket or a rubber gasket, etc. The above-mentioned gaskets are usually used in environments with relatively low temperature and pressure, and can basically meet the working requirements of the electronic atomization device.

[0076] As an optional embodiment, the interior of the battery shell 101 is provided with a receiving groove 1013 connected to the pin hole 1012 at a position corresponding to the power supply probe 102, and the seal 103 is located in the receiving groove 1013; wherein, the outer side surface of the seal 103 is in contact with the groove wall of the receiving groove 1013; and / or, the top surface of the seal 103 is in contact with the groove bottom of the receiving groove 1013, thereby preventing foreign matter from penetrating inward through the gap between the battery shell 101 and the seal 103.

[0077] Furthermore, the outer side surface and / or top surface of the seal 103 is provided with an outer sealing rib 1033. The outer sealing rib 1033 can be closely attached to the battery shell 101 to improve the sealing performance between the battery shell 101 and the seal 103.

[0078] As an optional implementation, the number of the inner sealing rib 1032 and / or the outer sealing rib 1033 may be one circle, or may be two circles, three circles or even more circles spaced from top to bottom, which is not limited in this embodiment.

[0079] In this embodiment, the power supply shell 1 also includes a fixing ring 104 clamped on the power supply probe 102. The fixing ring 104 is located on the side of the seal 103 away from the pin hole 1012, and is used to limit the relative movement between the seal 103 and the power supply probe 102 along the axial direction to prevent the seal 103 from falling off downward.

[0080] In this embodiment, each power supply probe 102 is provided with a corresponding fixing ring 104 , wherein at least one of the two fixing rings 104 is an insulating member, such as PEEK plastic, etc. Such a structural setting is conducive to avoiding short circuit between the two power supply probes 102 through the two fixing rings 104 .

[0081] Of course, in some other embodiments, the two fixing rings 104 can also be metal parts, which is beneficial to improve the structural strength and service life of the fixing ring 104. At this time, a spacing space is provided between the two fixing rings 104 to prevent the two fixing rings 104 from contacting each other and causing the two power supply probes 102 to short-circuit.

[0082] In summary, the power supply housing 1, the battery assembly, and the electronic atomization device provided in this embodiment have the following advantages:

[0083] ① The sealing member 103 is sleeved on the power supply probe 102, and is respectively in contact with the power supply probe 102 and the battery shell 101, thereby preventing foreign matter such as water, gasoline, and dirt on the outside of the battery shell 101 from entering the battery compartment 1011 through the gap between the sealing member 103 and the power supply probe 102 and / or through the gap between the sealing member 103 and the battery shell 101, thereby protecting other electronic devices in the battery compartment 1011 from damage;

[0084] ② The sealing member 103 is provided with an inner sealing rib 1032 and an outer sealing rib 1033, which is beneficial to improving the sealing performance;

[0085] ③ The two fixing rings 104 are insulated from each other, thereby preventing the two power supply probes 102 from being short-circuited.

[0086] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0087] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the utility model. They are not intended to limit the protection scope of the utility model.
