[0028] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0029] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0030] like Figures 1-5 As shown, this utility model discloses an installation accessory for an electric sprayer battery pack 3, which can be implemented in the following way. This accessory is mainly used to solve the problems of existing electric sprayer battery packs 3 being incompatible, having difficulty in compatibility with multiple models, and being inconvenient to install and disassemble. Through modular structure and standard interface design, different models of battery packs 3 can be quickly and safely installed into the same device host 1, improving the equipment's versatility and maintenance convenience.

[0031] The battery pack 3 mounting accessories include a device host 1. The device host 1 has a battery assembly cavity 5 inside to accommodate the battery pack 3. The battery assembly cavity 5 is an approximately rectangular spatial structure located on the side or bottom of the device host 1, facilitating battery installation and replacement by the user. The battery pack 3 is not directly fixed within the battery assembly cavity 5, but is connected via an intermediate conversion structure, namely, a battery accessory 2. This battery accessory 2 is an independent component, and its interface structure, which matches the battery pack 3, can be adapted to battery packs 3 of different sizes, shapes, or interfaces by replacing different models of battery accessories 2. This allows different types of battery packs 3 to be installed and used in a unified device host 1.

[0032] To ensure stable positioning of battery component 2 within the battery assembly cavity 5, positioning protrusions 6 are provided on both sides of the inner wall of the battery assembly cavity 5. These positioning protrusions 6 are structures that protrude inwards from the cavity and can be arranged in a strip or dot pattern, providing a certain positioning and limiting function. The battery component 2 is provided with a positioning slot 4 corresponding to the positioning protrusions 6. This slot is located at the outer edge of the battery component 2 and its size matches that of the positioning protrusions 6. When the battery component 2 is installed into the battery assembly cavity 5, the positioning slot 4 of the battery component 2 can accurately engage with the positioning protrusions 6, allowing the battery component 2 to automatically align and position itself during installation, preventing assembly misalignment and improving the accuracy and stability of the structural installation.

[0033] To further improve the connection accuracy and ease of operation between the battery pack 3 and the battery accessory 2, the battery pack 3 is provided with track grooves 9 on both sides of its top. These track grooves 9 are groove structures extending along the length of the battery pack 3. The battery accessory 2 is provided with track sliders 10 on both sides, which are sliding insertion structures adapted to the size of the track grooves 9. During installation, the user only needs to align the front end of the battery pack 3 with the track sliders 10 on the battery accessory 2, and then push the battery pack 3 forward along the sliding direction into the track grooves 9 until the battery pack 3 is fully embedded in the predetermined position. This sliding guide connection structure not only improves installation efficiency but also enhances the stability of the electrical and mechanical connections.

[0034] After the sliding installation is completed, to prevent the battery pack 3 from loosening or falling off due to external factors such as vibration or flipping during use, this utility model provides a locking structure on the battery pack 3 for further fixation. Specifically, a locking button 7 is provided on the upper surface of the battery pack 3, and one end of the button is provided with a locking hook 71. The locking hook 71 is naturally in a protruding state when the locking button 7 is not pressed. After the battery pack 3 slides into the battery accessory 2 to the predetermined position, the locking hook 71 automatically engages with the hook groove 8 provided on the battery accessory 2, thereby achieving mechanical locking. When it is necessary to replace or remove the battery pack 3, simply press the locking button 7 to retract the locking hook 71 and disengage it from the hook groove 8, and the battery pack 3 can be removed from the battery accessory 2 for quick replacement.

[0035] To ensure that the locking button 7 remains locked when not in use and to prevent accidental loosening, a compression support spring is provided at the bottom of the locking button 7. This spring applies an upward force to the button, causing the locking hook 71 to naturally protrude and lock into the hook groove 8. The support spring is made of a highly elastic metal material, ensuring its service life and reliability. This support spring design allows users to unlock the device with a single hand press, eliminating the need for complex hand movements and improving ease of use and human-computer interaction.

[0036] Furthermore, to further enhance the connection stability between the battery accessory 2 and the device host 1, and to prevent the battery accessory 2 from loosening or falling off during use, the battery accessory 2 is also equipped with a snap-fit ​​structure that cooperates with the device host 1. This snap-fit ​​structure can be configured as a flexible latch or a sliding latch structure. One end of the snap-fit ​​is fixed to the battery accessory 2, and the other end can cooperate with a fixing hole or locking structure inside the host to achieve a reliable detachable connection. With this snap-fit ​​structure, after the user completes the assembly of the battery accessory 2 into the device host 1, a simple push and snap is all it takes to secure it, ensuring structural strength and facilitating future maintenance and replacement of different battery accessories 2.

[0037] The battery pack 3 mounting accessories for this electric sprayer feature a split design, combined with multiple structural components such as positioning, sliding rails, locking buckles, and clips. This not only solves the problem of incompatibility between different battery pack 3 models, but also improves assembly efficiency and structural stability, providing users with great convenience when replacing battery pack 3. It is particularly suitable for the flexible use needs of electric sprayers in long-term operation, multiple battery replacement, and different application scenarios, and has broad application value.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
