[0036] Reference Figure 1 As shown, the utility model provides an embedded battery module for a battery-detachable electric blowpipe, comprising:

[0037] The battery bottom shell 4 is a long strip structure with an opening on one side and a hollow interior, adapted to the battery compartment of the battery-detachable electric blowpipe;

[0038] The battery cell 5 is located in the cavity inside the battery bottom shell 4;

[0039] A battery upper cover 6, which is mounted on the opening of the battery bottom shell 4;

[0040] A charge and discharge plate 2, which is installed in a receiving groove on one end surface of the battery bottom shell 4 and is electrically connected to the battery cell 5 through a wire;

[0041] The battery spring piece 7 is installed on the other end surface of the battery bottom shell 4 and connected to the charging and discharging plate 2 through a wire; when installed, the battery spring piece 7 abuts against the battery connecting piece in the battery compartment;

[0042] The electric board protection component 1 is made of a transparent material and is installed on the surface of the accommodating tank and is located above the charging and discharging board 2 to form an observation window;

[0043] Tighten the screws 3 to fix the battery bottom shell 4 in the battery compartment.

[0044] In this embodiment, one side of the battery bottom shell is open, and the battery cover can be installed on the open side. The battery cover is provided with 6 clamping feet, which sink into the slot in the battery bottom shell when clamped, and cannot be directly lifted to open or retreated. This sinking design has an anti-disassembly function. Through the close cooperation between the sinking clamping feet and the slot, the stable connection and efficient anti-disassembly function of the battery assembly are achieved, providing users with a safer and more reliable use experience, and effectively preventing the risks caused by accidental disassembly or misoperation.

[0045] The cross-sections at both ends of the battery bottom shell are trapezoidal structures, with their long sides being on the same plane as the battery cover. After installation, they fit together into the battery compartment of the detachable electric blowpipe. The short sides and the surfaces where the two oblique sides are located are provided with anti-slip structures for easy installation. The trapezoidal structure design is not easy to block the line of sight during installation, making operation convenient.

[0046] In the design process, the anti-skid structure is a crucial consideration, which directly affects the user experience and safety of the device. Therefore, in this embodiment, a variety of innovative designs are made in the setting of the anti-skid structure.

[0047] First, the anti-slip structure can be designed as a concave-convex pattern. This design increases the friction between the hand and the shell through the ups and downs of the pattern, effectively preventing accidents caused by sliding of the battery module during installation. The shape and depth of the pattern can be flexibly adjusted to ensure that while providing sufficient anti-slip effect, it also complies with ergonomic principles and brings users a comfortable grip.

[0048] In addition, the anti-slip structure can also be designed with dot-shaped protrusions. This design uses scattered protrusions to maintain the simple and beautiful appearance of the battery module (battery bottom shell) while also increasing the stability when holding.

[0049] In addition to the above two designs, the present embodiment can also choose to set the anti-skid structure as a plurality of V-shaped anti-skid grooves. This design utilizes the special shape of the V-shape, so that the gripping stability can be better enhanced when holding the battery module.

[0050] In the overall design of the battery module, in order to avoid the problem of overly sharp corners, this embodiment also makes humanized improvements. Specifically, the connection of the battery bottom shell structure can be designed to be arc-shaped; in addition, it is also possible to choose to cut off a part of all right-angled edges to reduce the contact area of ​​the corners with the human body, thereby further reducing the risk of accidental injury. These improved designs not only improve the safety of holding the battery module, but also improve the user experience.

[0051] In one embodiment, the battery bottom shell 4 is made of plastic or composite material. From the perspective of environmental protection and safety, plastic can be made of pure PC material, which is also one of the main materials for the outer shell of current power products. Composite materials such as highly flame-retardant polypropylene composite materials, PP composite materials, etc. are all lightweight and have excellent waterproof and fireproof properties.

[0052] Specifically, the highly flame-retardant polypropylene composite material includes: polypropylene, glass fiber, modified boehmite, diatomaceous earth, fullerene, flame retardant, toughening agent, antioxidant, etc.; the PP composite material includes: PP, PBT, modified basalt fiber, modified magnesium borate whisker, SEBS-g-MAH, antioxidant, etc.

[0053] The battery cells are placed in the inner cavity of the battery bottom shell to adapt to the power supply voltage of the electric blowpipe. For example, if the total voltage is 7.4v, two groups of 3.7v battery cells can be connected in series. In order to achieve a higher capacity when the total voltage remains unchanged, multiple groups of battery cells can be used in series and then in parallel, so that the battery life on a single charge can reach more than 10 hours.

[0054] In this embodiment, the battery cell is a 18650 lithium battery or a polymer battery, wherein the 18650 lithium battery and the polymer battery are both lithium-ion cells.

[0055] The nominal voltage of 18650 lithium battery is 3.7v, and the charging cut-off voltage is 4.2v. It has the advantages of high energy density, light weight, large capacity, and no memory effect. Polymer battery, also known as high-molecular lithium battery, has many obvious advantages such as high energy density, smaller size, ultra-thinness, light weight, and high safety. You can make a reasonable choice based on the geographical area where the electric blowpipe users are located and the economic cost.

[0056] In the specific implementation, the internal space of the battery bottom shell is fully utilized and the position of the battery cells is reasonably designed, so as to ensure the capacity and performance of the battery cells and ensure that the battery module remains light while having sufficient battery life.

[0057] In addition, the lithium-ion battery cell is equipped with an existing battery protection board on the market, which is an integrated circuit board that protects the lithium battery. The battery protection board is mainly composed of a control IC, MOS tube, resistor, capacitor, fuse, PTC, and NTC. It has functions such as overcharge protection, over-discharge protection, short circuit protection, overcurrent protection, and ultra-high temperature protection, which extend the service life of the battery cell and prevent the battery cell from being scrapped or exploding.

[0058] In this embodiment, a charge and discharge board with a QC fast charging function is installed in the accommodating groove on the surface of one end of the battery bottom shell. The charge and discharge board can be, for example, a two-string 7.4V lithium battery protection board available on the market. It is a distribution board used to monitor, control and protect the charging and discharging of battery cells. By monitoring the voltage and current of the battery cells, the purpose of protecting the battery cells and saving electric energy is achieved. When the lithium battery cells are charging, it ensures that each battery cell in series can be charged evenly to protect the battery cells.

[0059] The charging interface of the charging and discharging board can be any one of the Type-C interface, Micro USB interface and Lightning interface; any charging interface can be seamlessly connected with the mainstream charging power cord on the market, which brings great convenience and flexibility to charging.

[0060] First, the charging and discharging board can be set up with a Type-C interface; the Type-C interface has greatly improved its fast charging capability and data transmission speed; not only that, the Type-C interface also has the advantage of being usable in both directions, greatly reducing the trouble when inserting the interface, making charging easier and faster. Secondly, the charging and discharging board can also be set up with a MicroUSB interface; the Micro USB interface is widely used in smartphones, tablets and other devices, demonstrating its wide compatibility and practicality. Finally, it can be a Lightning interface; as an exclusive interface for Apple devices, the Lightning interface has won the love of many users with its unique design and excellent performance; the charging and discharging board supports the Lightning interface, which means that Apple users can also charge quickly and conveniently.

[0061] In general, whether it is the Type-C interface, Micro USB interface or Lightning interface, it can bring a convenient and efficient charging experience. At the same time, this diverse interface design also demonstrates the strong compatibility and adaptability of the charging and discharging board.

[0062] The charging interface can be externally connected through the through hole of the battery bottom shell. When charging, it is connected to the external power supply through the power cord. The charging end of the charging and discharging board is electrically connected to the battery cell through a wire to charge the battery cell. A charging indicator light is provided on the charging and discharging board. The red and blue lights are always on during charging. The blue light goes out when it is fully charged, and the red light goes out after the power cord is unplugged. The discharging end of the charging and discharging board is connected to the battery shrapnel through a wire. When installed, the battery shrapnel abuts against the battery connecting piece in the battery compartment.

[0063] The charging and discharging board also has a power display function, such as an LED indicator light display, an LED digital tube, an LCD screen, etc., which can display the power level intuitively and clearly; the information on the remaining battery power can be grasped at any time to determine whether the performance process can proceed smoothly.

[0064] The surface of the battery bottom shell accommodating groove is installed with a board protection component, which protects the charging and discharging board on the one hand, and is made of transparent material on the other hand, so that the charging and discharging conditions and the power display can be observed, forming an observation window.

[0065] In this embodiment, one end of the battery bottom shell where the accommodating groove is located adopts a slope design, so the charging and discharging plate and the battery plate protection assembly are placed at an angle, which is convenient for observing the charging and discharging conditions and the power display conditions.

[0066] One end of the battery bottom shell receiving groove has a threaded hole adapted to the original battery compartment, corresponding to the threaded hole on the original battery compartment. The battery bottom shell can be fixed in the battery compartment by tightening the screws; it not only ensures the stability of the battery module, but also facilitates disassembly; at the same time, the slope design of the battery bottom shell receiving groove is also conducive to the installation and fixation of the tightening screws.

[0067] Reference Figure 2 As shown, in order to adapt to the battery compartments of different electric blowpipes, the positions of the battery shrapnel are different; Figure 2 In the battery modules in the middle part and on the right, the battery shrapnel has different heights, but both are located at the end of the battery bottom shell away from the observation window. The battery bottom shell can be designed with a slope, and the specific position of the battery shrapnel needs to be adapted to the battery compartment of the electric blowpipe. Figure 2 In the battery module on the left, the battery shrapnel is located at one end of the battery bottom shell close to the observation window. It does not support a sloped design. The battery bottom shell receiving groove can be opened from the front, and the board protection component can be installed from the front for easy observation.

[0068] The battery shrapnel is made of copper, iron or stainless steel, and is electroplated with CT, silver or nickel. Its shape and size must be adapted to the battery connector in the battery compartment. After installation, the battery shrapnel elastically contacts the battery connector in the battery compartment to form a stable current path, providing continuous and stable power support for the electric blowpipe. Whether in various occasions such as playing, practicing or performing, it can stably and reliably power the electric blowpipe.

[0069] Reference Figure 3 As shown in the figure, A is the battery compartment of the removable battery electric blowpipe, and Figure 4 It is a partial schematic diagram after adopting the battery module of the utility model, B is the battery module of the utility model; the embedded battery module is embedded in the electric blowpipe, the battery spring of the battery module is abutted against the connecting piece in the battery compartment of the electric blowpipe, and the power supply is output to replace its original power supply mode.

[0070] The embedded battery module of the utility model can be embedded in the battery compartment of the electric blowpipe through structural design, and docked with the original battery compartment to replace the original power supply mode. It adopts lithium battery cells, and uses 2 groups of cells in series or multiple groups of cells in series and then in parallel, and has a built-in cell protection board, so that a higher capacity can be achieved under the condition of unchanged total voltage, and the battery life can reach more than 10 hours on a single charge. It also has a QC fast charging function, and the charging time is greatly reduced, with the characteristics of fast charging and long battery life.

[0071] The utility model has a simple structural design, and the components are closely matched and compact in structure. It can not only meet the power demand of the electric blowpipe, but also is convenient for installation, inspection and maintenance, and takes the safety, stability and usability of the battery into consideration; it is conducive to the replacement and upgrading of the battery.
