Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, and in particular to an energy storage device, an electrical device and an atomizer. Background Art

[0002] A battery is a device that has positive and negative electrode materials, which determine the battery voltage. It can convert chemical energy into electrical energy by transferring electrons generated by electrochemical changes on the positive and negative electrodes between the positive and negative electrodes in an external circuit to generate current. The more common batteries are lithium batteries, nickel-cadmium batteries, and nickel-metal hydride batteries. The performance parameters of batteries mainly include voltage, capacity, energy density, and resistance. Using batteries as an energy source can obtain current with stable voltage, stable current, long-term stable power supply, and little external influence. In addition, the energy storage device is simple, easy to carry, easy to charge and discharge, strong environmental adaptability, stable and reliable performance, and plays a great role in all aspects of modern social life.

[0003] With the development of social technology, more and more devices are becoming intelligent and electronic, and rechargeable energy storage devices have become the energy center of these devices. Currently, most electronic products that carry rechargeable energy storage devices use embedded batteries, which directly encapsulate lithium batteries inside the device. There are also electronic products with replaceable batteries on the market, such as various remote controls. These products have the following two main disadvantages: First, due to the battery cover, the volume utilization rate of this type of product is low, so the energy density that can be provided by the same volume is low (for example, there is a battery cover at the battery replacement position of the remote control); second, the use steps of this type of electronic product are complicated, and the battery needs to be installed first, and then the battery cover is closed.

[0004] The above existing products have the following disadvantages:

[0005] At present, these electronic products have the following main disadvantages: First, it is difficult to repair the damaged battery, and the host needs to be disassembled for repair. At present, the host of many electronic devices is difficult to disassemble, and many consumers directly discard the host after the host is used, resulting in a waste of resources; second, it is difficult to remove the battery when the product is discarded for classified recycling, and the battery is often discarded with the product, causing environmental pollution; third, the volume utilization rate of the product is low. The same volume requires a battery cover, which reduces the space that can accommodate the battery, resulting in a reduction in the space that the product can actually provide energy to the battery, resulting in a decrease in the battery life of the device; fourth, the traditional remote control-style battery replacement method, due to the large number of connection points of the device, causes the overall internal resistance of the energy storage component to be high. Moreover, with the latest battery bill announced in Europe, the batteries of digital products are required to be removable. This can not only protect the environment (discarding used batteries will pollute the environment), but also extend the life of electronic products (traditional electronic products with built-in batteries are directly discarded after the device cannot be used. There are two main reasons: first, many electronic products are glued during production for the sake of beauty and stability, without considering subsequent disassembly and recycling; second, disassembling these products requires professional knowledge, many users lack the corresponding professional knowledge, and the cost of repairing them at repair shops is high. Therefore, in the future, the battery of electronic products will be separated and made into a detachable independent component. This will not only increase the service life of electronic products, but also because the battery circuit is separated from the circuit of the whole machine, when the battery is damaged, the user can replace a battery without professional knowledge to determine whether it is the host or the battery that is damaged. When the device is damaged, the battery can be directly removed and recycled separately, which will become a new trend in electronic products.

[0006] In the future, it will be a new technological trend to make the energy storage part of traditional electronic products detachable as a whole. The electronic products include but are not limited to handheld fans, flashlights, atomizers, shavers, laser pens and other devices. Utility Model Content

[0042] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0043] This embodiment provides an energy storage device, which is used to be installed on a functional device to power the functional device, including: an energy storage part 1; a first docking part 102, which is installed on the energy storage part, and the first docking part 102 is provided with a docking male head, and the docking male head is provided with a male head docking surface, and the male head docking surface is provided with a positive electrode 104a and a negative electrode 104b, and the positive electrode 104a and the negative electrode 104b are connected to the energy storage part 1. Among them, the energy storage part is a component with a battery or a capacitor for providing electrical energy, and the first docking part 102 is used to dock and fix to the functional device, and the functional device is a device that can complete a specific function after power supply, such as a flashlight, an atomizer, a hair dryer, a shaver, and other devices.

[0044] During implementation, the first docking portion 102 is installed on the energy storage portion, and the docking male head 103 on the first docking portion 102 is used to install the energy storage portion 1 on a device having a docking female head that cooperates with the docking male head, thereby realizing the snap connection between the first docking portion 102 and the functional device. After the assembly is completed, the electrode connection points on the functional device are connected to the positive and negative electrodes on the male head docking surface, thereby realizing power supply for the device. Firstly, the energy storage device provided in this embodiment is installed on the functional device as a whole through the first docking portion 102, and the docking male head is connected to the functional device as a fixed structure, thereby realizing installation and disassembly. When the energy storage portion 1 is damaged, it only needs to be removed from the functional device using the first docking portion 102, and there is no need to discard the entire device that needs energy supply, thereby avoiding waste of resources. Secondly, since only the energy storage device can be replaced, environmental pollution caused by discarding the device with a battery is avoided. Finally, since the energy storage device provided in this embodiment is separately provided, there is no need to set various connection points on the device that needs energy supply, and only the electrode connection points connected to the positive and negative electrodes on the energy storage portion need to be provided, thereby reducing the overall internal resistance of the functional device. Traditional functional devices are powered by setting a battery mounting slot on the functional device, placing the battery in the mounting slot, and then covering the slot with an outer cover. In the present application, the energy storage part can be directly installed on the functional device using the first docking part, avoiding the need to set a mounting slot on the functional device, improving the space utilization of the energy storage device, and thus improving the space density of the energy storage part.

[0045] In some embodiments, the male connector is a snap-fit ​​structure, a slot structure, or a threaded structure.

[0046] During implementation, the male docking head can be one of a buckle structure, a slot structure, and a threaded structure provided on the first docking portion. The energy storage portion is fixed by these detachable connection structures to power the functional device, thereby realizing a detachable connection mode.

[0047] In a series of embodiments, the card slot structure includes a first card slot 113 and a second card slot 123, the first card slot 113 and the second card slot 123 are symmetrically arranged, the first card slot 113 and the second card slot 123 have the same structure, including a positioning slot 103a and a snap-on slot 103b, the positioning slot 103a is provided with an opening on the first docking portion 102, the snap-on protrusion 103c is provided on the side wall of the snap-on slot 103b, and the positioning slot 103a is communicated with the snap-on slot 103b.

[0048] During implementation, the card slot structure sets the first card slot 113 and the second card slot 123, and the first card slot 113 and the second card slot 123 are symmetrically arranged so that the docking male head can be more stably clamped on the functional device, and the positioning slots 103a on the first card slot 113 and the second card slot 123 are used to align the position of the card head 202 on the functional device, and then the card head 202 is moved into the positioning slot 103a by pushing. The positioning slot 103a and the snap-on slot 103b are connected. After the card head 202 enters the positioning slot 103a, the first docking part 102 is rotated to make the card head 202 enter the snap-on slot 103b, thereby completing the snap connection. The snap-on protrusion 103c in the snap-on slot 103b can improve the stability of the snap connection. Specifically, the docking male head is a cylindrical structure, and the first card slot 113 and the second card slot 123 are arranged on the side of the docking male head, and the first card slot 113 and the second card slot 123 are symmetrically arranged with the center of the docking male head.

[0049] In some embodiments, the positioning sub-groove of the first slot 113 and the positioning sub-groove of the second slot 123 have different groove widths and / or groove depths.

[0050] During implementation, the groove width and groove depth of the positioning groove in the first card slot 113 are set to be different from the groove width and groove depth of the positioning groove in the second card slot 123 to avoid and remind the user of reverse carding. Usually, the first clamping head 212 and the second clamping head 222 corresponding to the width and groove depth of the positioning groove are also set on the functional device. When the card is reversed, the first card slot 113 and the second card slot 123 cannot correspond to the shape of the first clamping head 212 and the second clamping head 222, and the docking male head cannot be inserted into the functional device. Only correct operation can make the docking male head inserted into the functional device, thereby reminding and avoiding reverse carding for the user. Such a setting method includes that the groove width of the positioning groove of the first card slot 113 is different from the groove width of the positioning groove of the second card slot 123, or the groove depth of the positioning groove of the first card slot 113 is different from the groove depth of the positioning groove of the second card slot 123, or the groove width and groove depth of the positioning groove of the first card slot 113 and the second card slot 123 are different. The above methods can avoid reverse carding.

[0051] In some embodiments, the slot width and / or slot depth of the snap-in slot of the first snap-in slot 113 and the snap-in slot of the second snap-in slot 123 are different.

[0052] During implementation, the groove width and groove depth of the snap-in sub-groove in the first snap-in slot 113 are set to be different from the groove width and groove depth of the snap-in sub-groove in the second snap-in slot 123 to avoid and remind the user to insert the card in reverse. Usually, the functional device will also be provided with a first clamping head 212 and a second clamping head 222 corresponding to the groove width and groove depth of the snap-in sub-groove. When the card is inserted in reverse, the snap-in sub-groove in the first snap-in slot 113 and the snap-in sub-groove in the second snap-in slot 123 cannot correspond to the shape of the first clamping head 212 and the second clamping head 222, and the docking male head cannot be inserted into the functional device. Only correct operation can make the docking male head snap into the functional device, so as to remind and avoid reverse jamming for the user. Such setting methods include that the slot width of the first card slot 113 and the slot width of the second card slot 123 are different, or the slot depth of the first card slot 113 and the slot depth of the second card slot 123 are different, or the slot width and slot depth of the first card slot 113 and the second card slot 123 are different. All of the above methods can avoid reverse jamming.

[0053] In the energy storage device of conventional electronic products, the positive and negative electrodes 104b are connected in a centrally symmetrical manner. This connection method may cause the battery to catch fire and explode when the positive and negative electrodes on the energy storage device and the electrode connection points of the functional device are connected in reverse.

[0054] Therefore, in some embodiments, the positive electrode 104a and the negative electrode 104b are arranged non-centrosymmetrically on the butt joint surface.

[0055] During implementation, when the user reversely connects the first docking part 102 to the functional device, the positive and negative electrodes 104b cannot contact the first docking part 102, the electrode connection point on the functional device, so that power cannot be supplied and a short circuit will not be caused. Only when the first docking part 102 is correctly connected to the functional device, the positive and negative electrodes 104b will contact the first docking part 102, thereby effectively preventing the battery from short-circuiting and catching fire when the first docking part 102 is connected reversely.

[0056] Specifically, the positive electrode 104a and the negative electrode 104b are arranged non-center-symmetrically on the docking surface, and the corresponding positive and negative electrode contact electrodes, the two contact electrodes are arranged non-center-symmetrically; in some cases, on the male head docking surface, the positive electrode and the negative electrode can also be arranged in a shape of positive inside and negative outside, that is, the raised part in the middle is the positive electrode, and the plane surrounding the positive electrode is the negative electrode. This arrangement can also prevent the electrodes from being connected in reverse.

[0057] In some embodiments, the energy storage unit further includes a first shell 105 and an energy storage unit, wherein the energy storage unit 101 is installed in the first shell 105, the first docking portion is installed on the top of the first shell, and the energy storage unit connects the positive electrode 104a and the negative electrode 104b on the docking male connector, wherein the first shell 105 is used to protect the energy storage unit 101 and support the first docking portion 102, and the energy storage unit 101 is the main energy storage unit. The energy storage unit is an independent battery or capacitor.

[0058] During implementation, the energy storage unit 101 is placed inside the first shell 105, and then the first docking portion 102 is installed on the first shell 105. The first shell 105 protects the energy storage unit 101. When the energy storage device provided by this embodiment is installed on a functional device, the first shell 105 can be held by hand to screw and clip the first docking portion 102 onto the functional device.

[0059] Specifically, in this embodiment, the energy storage unit is illustrated by taking a battery as an example, the first shell 105 is cylindrical, the first docking portion 102 is cylindrical cover-shaped, the first docking portion is connected to the first shell by a snap-fit, the first shell 105 is snap-fitted to the first docking portion 102, the energy storage unit 101 is a battery, during assembly, the battery is first placed in the first shell 105, and then the first shell 105 is mounted on the first shell 105 by a snap-fit, the negative electrode in the battery is electrically connected to the negative electrode 104b on the docking male connector by setting a wire in the first shell, the top of the battery is the positive electrode, and the positive electrode of the battery is directly in contact with the positive electrode 104a on the docking male connector.

[0060] In some cases, the first shell 105, the first docking part 102 and the energy storage unit 101 are integrated, that is, the first shell and the first docking part directly form a shell, the shell has a housing cavity, and the energy storage unit 101 is located in the housing cavity. This method does not require additional assembly and can be used, which reduces the assembly steps and improves the convenience of use. In addition, the first shell 105, the first docking part 102, and the energy storage unit are integrated to reduce the invalid volume between the first docking part and the first shell 105, improve the internal volume utilization, and thus improve the overall energy density. The energy storage unit is a winding core, which is a structure formed by winding a pole piece and a diaphragm.

[0061] In order to adapt to the power supply specifications of different electrical devices, multiple energy storage units connected in series can be arranged in the first shell. For example, if the energy storage unit is a battery, multiple batteries can be connected in series and then installed in the first shell to form a battery pack, which is then installed on the electrical device through the first docking portion of the first shell. Common electrical devices of this type include high-speed hair dryers, handheld electric drills, power tools, etc.

[0062] In some embodiments, a first PCB board 106 is disposed in the first housing 105, and the first PCB board 106 is electrically connected to the energy storage unit 101. A charging connector 107 is disposed on the first housing 105, and the charging connector 107 is electrically connected to the first PCB board 106. A charging circuit is disposed on the first PCB board.

[0063] During implementation, the first PCB board 106 and the energy storage unit 101 are installed in the first shell 105, and the energy storage unit 101 is electrically connected to the first PCB board 106. The charging connector 107 on the first shell 105 is electrically connected to the first PCB board 106. The charging connector 107 can be connected to an external charger, and then the energy storage unit 101 can be charged through the charging circuit in the first PCB board 106, thereby realizing sustainable use of an energy storage device provided by this embodiment.

[0064] Specifically, in this embodiment, the charging connector 107 adopts a type-C interface. In some cases, the charging connector 107 may also adopt a USB interface, etc. The utility model does not limit the type of the charging connector 107. The charging connector 107 can be set on the side of the first shell 105 or on the bottom of the first shell 105.

[0065] In some embodiments, a bottom cover 108 is provided at the bottom of the first shell 105 , and an opening corresponding to the shape of the charging connector 107 is provided on the bottom cover 108 . The charging connector 107 is located in the opening of the bottom cover 108 , and the first PCB board 106 is mounted on the bottom cover 108 .

[0066] During implementation, after the first PCB board 106 is installed in the first shell 105, the bottom cover 108 is installed at the bottom of the first shell 105 and the opening on the bottom cover 108 is aligned with the charging connector 107 so that the charging connector 107 is located in the opening of the bottom cover 108. The external charger can pass through the opening on the bottom cover 108 to connect with the charging connector 107. The opening on the bottom cover 108 can limit the connector of the charger to keep it stable. The bottom cover 108 can also prevent the first PCB board 106 and the internal energy storage unit 101 from falling off from the first shell 105.

[0067] In some cases, some devices may have a storage cavity. When the energy storage device provided in this embodiment is installed on the device, the energy storage device as a whole will be accommodated in the storage cavity, and the first docking portion 102 cannot be removed by twisting the first shell 105 by hand. At this time, the connector of the external charger can be inserted into the opening on the bottom cover 108, and then the connector of the charger can be rotated to remove the entire device from the storage cavity of the device. Therefore, the opening on the bottom cover 108 can also serve to assist assembly and disassembly.

[0068] Specifically, the bottom cover 108 is connected to the first shell 105 via a snap-fit ​​connection.

[0069] In some cases, a display screen (not shown in the figure) may also be provided on the bottom cover 108 , and the display screen is electrically connected to the first PCB board, and the display screen is used to display the remaining power.

[0070] In some embodiments, a screwing notch 109 is disposed at the bottom of the first shell 105 .

[0071] During implementation, the purpose of providing the screwing notch 109 at the bottom of the first housing 105 is to enable the first housing 105 to be removed by using a tool such as a screwdriver in conjunction with the screwing notch 109 .

[0072] Specifically, the screwing notch 109 includes a straight notch, a cross notch, a hexagonal notch, a star notch, etc. According to the shape of the screwing notch 109, a screwdriver with a blade of the same shape can be used to screw the energy storage device for assembly or disassembly, thereby solving the problem that the energy storage device cannot be removed by rotating the first housing 105 by hand in some cases. Figure 4 As shown, a straight-shaped notch is provided at the bottom of the first shell, and an opening can be further provided on the side of the first shell, and the charging connector of the first PCB board can be provided in the opening of the first shell.

Since the energy storage device has been described in detail in the above embodiment, it will not be repeated in this embodiment. Among them, the electrical device may include a fan, an electric shaver, an atomizer and other electrical devices that require power supply. The energy storage device provided in this embodiment can be used as the energy storage part of the above electrical device to supply power, thereby realizing the detachability of the battery and making the assembly method simple.

[0074] During implementation, the male docking connector on the first docking portion of the energy storage device is connected with the female docking connector on the second docking portion of the functional device. When the male docking connector and the female docking connector are correctly docked, the positive electrode 104a and the negative electrode 104b on the male docking connector respectively contact the electrode connection points on the female docking connector, thereby achieving charging.

[0075] In some embodiments, the docking female connector is one of a snap-fit ​​structure, a slot structure, and a threaded structure.

[0076] During implementation, the docking female head is connected to the docking male head through one of the snap-fit ​​structure, the slot structure, and the threaded structure. Since these are detachable connection methods, the detachable connection between the docking female head and the docking male head is achieved, which is convenient for installation and disassembly.

[0077] In some embodiments, the buckle structure includes a first clamping head 212 and a second clamping head 222 . The first clamping head 212 and the second clamping head 222 are symmetrically arranged. The first clamping head 212 and the second clamping head 222 are provided with clamping notches.

[0078] During implementation, the energy storage device is correspondingly provided with a first card slot 113 and a second card slot 123. When the energy storage device is installed on the functional device, the first card slot 113 is correspondingly engaged with the first card head 212, and the second card slot 123 is correspondingly engaged with the second card head 222, thereby completing docking. When the first card slot 113 and the second card slot 123 correspondingly provided on the energy storage device are provided with engaging protrusions, the first card head 212 and the second card head 222 are provided with engaging notches 202a that cooperate with the engaging protrusions 103c. When the first card head 212 and the second card head 222 are inserted into the first card slot 113103 and the second card slot 123, the engaging protrusions 103c will be engaged with the engaging notches 202a, thereby improving the connection stability between the docking male head and the docking female head. Secondly, after the engaging protrusions 103c are engaged with the engaging notches 202a, there will be an engaging sound and a sense of vibration, and the engaging sound and the sense of vibration can remind the user that the engaging is in place.

[0079] In some embodiments, the first clamp 212 and the second clamp 222 have different widths and thicknesses.

[0080] During implementation, when the female docking head on the functional device is set to a snap-on structure, and the male docking head on the energy storage device is set to a slot structure, the shape of the first clamping head 212 will be consistent with the shape of the clamping slot in the first slot 113, and the shape of the second clamping head 222 will be consistent with the shape of the clamping slot in the second slot 123. Therefore, the shapes of the first clamping head 212 and the second clamping head 222 are adapted to the clamping slot in the energy storage device. The widths and thicknesses of the first clamping head 212 and the second clamping head 222 are set to be different, which can also avoid and remind the user to get stuck in reverse. When the card is reversed, the clamping head in the first slot 113 The connecting sub-slots in the sub-slot and the second card slot 123 cannot correspond to the shapes of the first card head 212 and the second card head 222 respectively, and the docking male head cannot be inserted into the functional device. Only correct operation can make the docking male head inserted into the functional device, thereby reminding the user and avoiding reverse card insertion. Such a setting method includes that the width of the first card head 212 is different from the width of the second card head 222, or the thickness of the first card head 212 is different from the thickness of the second card head 222, or the width and thickness of the first card head 212 and the second card head 222 are different. The above methods can all avoid reverse card insertion.

[0081] In some embodiments, the two electrode connection points are asymmetrically arranged on the female connector docking surface.

[0082] During implementation, the two electrode connection points are set to be non-center symmetrical on the female head docking surface, and the positive electrode 104a and the negative electrode 104b on the energy storage device correspond to each other. When the user connects the first docking part 102 to the functional device in reverse, the positive and negative electrodes 104b cannot contact the electrode connection points on the functional device, so that power cannot be supplied and a short circuit will not be caused. Only when the first docking part 102 is correctly connected to the functional device, the positive and negative electrodes 104b will contact the first docking part 102, thereby effectively preventing the battery from short-circuiting and catching fire when the first docking part 102 is connected in reverse.

[0083] This embodiment provides an atomizer, comprising: a functional device and an energy storage device in an electrical device; wherein the functional device further comprises: a second shell, the second docking portion is mounted on the bottom of the second shell, a nozzle is provided on the top of the second shell, an air inlet is provided on the second docking portion, and an air passage is formed in the second shell with the nozzle and the air inlet; an atomizer assembly is mounted in the second shell;

[0084] The second PCB board is electrically connected to the atomizer assembly, and the two electrode connection points are electrically connected to the second PCB board. The atomizer assembly 206 is used to atomize the e-liquid into smoke, and the second PCB board 207 is provided with a start circuit for starting the atomizer assembly 206.

[0085] During implementation, the second docking portion 201 is installed at the bottom of the second housing 203, and then the atomizer assembly 206 and the second PCB board 207 are electrically connected through a wire, and then the atomizer assembly 206 and the second PCB board 207 are installed in the second housing 203, and then the nozzle 204 is installed on the top of the second housing 203. After the assembly is completed, the first docking portion 102 in the energy storage device is docked with the second docking portion 201 in the atomizer, and the positive electrode on the docking male head is connected to the positive electrode 202 of the atomizer. The positive electrode 104a and the negative electrode 104b contact two electrode connection points on the second PCB board 207, thereby realizing power supply. After docking, the user inhales from the mouthpiece 204, and air enters from the air inlet 205 on the side of the second docking part 201. The air reaches the mouthpiece 204 through the airway. The air entering from the air inlet passes through the second PCB board 207 to trigger the starting circuit, and the starting circuit then pneumatically drives the atomizer assembly 206 to atomize the smoke oil in the atomizer assembly 206, and finally the user inhales smoke from the mouthpiece 204. The air inlet 205 of the traditional atomizer is arranged at the bottom of the overall device, and the distance between the air inlet 205 and the suction nozzle 204 is relatively far, that is, the gas entering from the air inlet 205 needs to pass through the energy storage part and the functional device 2 to reach the suction nozzle 204, so the time required is longer, which will cause the response speed of atomization and inhalation to be slower. The air inlet 205 in this embodiment is arranged on the side of the second docking part 201, and the energy storage device is installed at the bottom of the second docking part 201. Therefore, when the gas enters from the air inlet 205, it only needs to pass through the functional device 2, and does not need to pass through the energy storage part in the energy storage device, thereby reducing the distance of gas circulation, thereby improving the response speed of atomization and further improving the user's experience.
