A false insertion prevention structure for an electric spray battery pack

Abstract

This utility model discloses a battery pack anti-misinsertion structure for an electric sprayer, including a spraying main unit and a limit switching component. The spraying main unit has at least two battery chambers for inserting battery packs of different voltages. The limit switching component is disposed between the two battery chambers and is used to switch its limiting position according to the insertion state of the battery pack. When a battery pack is inserted into one battery chamber, the limit switching component automatically protrudes into the adjacent battery chamber, preventing the other battery pack from being inserted simultaneously. This effectively avoids electrical faults caused by voltage mismatch, improves the safety and system compatibility of the equipment, and features a simple structure, convenient operation, and broad application prospects.

Description

Technical Field

[0001] This utility model relates to the field of electric sprayers, specifically to a battery pack anti-misinsertion structure for electric sprayers. Background Technology

[0002] With the widespread use of portable spraying equipment in agriculture, horticulture, public health, and other fields, the replaceability and compatibility of batteries, as the main power supply unit for sprayers, have become key concerns for users. Currently, various battery packs with different voltage specifications are available on the market, and different users may have multiple battery pack models depending on their usage intensity and equipment specifications. To enhance the adaptability of sprayers and expand their compatibility, some sprayer products have begun to incorporate multiple battery mounting chambers, allowing users to select the appropriate battery pack for power supply based on their specific needs.

[0003] However, in the existing technology, although sprayers can provide multiple battery chambers, they usually lack effective physical or structural limiting mechanisms. This can lead to users inserting battery packs with different voltages into two battery chambers at the same time, causing safety hazards such as electrical short circuits, overvoltage damage, and battery performance degradation. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a battery pack anti-misinsertion structure for electric sprayers, which effectively overcomes the shortcomings of existing technologies.

[0005] This utility model is achieved through the following technical solution: a battery pack anti-misinsertion structure for an electric sprayer, comprising:

[0006] A spray host having at least two battery chambers, into which battery packs of different voltages are inserted;

[0007] A limiting switch is disposed between at least two battery compartments. When the battery pack is inserted into one of the battery compartments, the limiting switch protrudes into the adjacent battery compartment to restrict the insertion of the remaining battery pack into the battery compartment.

[0008] As a preferred technical solution, at least two battery cavities include a first battery cavity and a second battery cavity. When the battery pack is inserted into the first battery cavity, the limiting switching member protrudes into the second battery cavity.

[0009] When the battery pack is inserted into the second battery cavity, the limiting switch protrudes into the first battery cavity.

[0010] As a preferred technical solution, the limiting switching component has two limiting surfaces, and a rotating shaft is provided on each side of the limiting switching component. The limiting switching component is installed on the spray host through the rotating shaft.

[0011] As a preferred technical solution, a torsion spring is installed on the rotating shaft.

[0012] As a preferred technical solution, the two limiting surfaces include a first limiting surface and a second limiting surface, the first limiting surface and the second limiting surface are arranged perpendicular to each other, and the rotating shaft is arranged at a right angle position between the two limiting surfaces.

[0013] As a preferred technical solution, a mounting cavity is formed between the first battery cavity and the second battery cavity, and the limiting switching component is elastically rotatably installed in the mounting cavity.

[0014] As a preferred technical solution, a battery cover is installed on the outside of each of the two battery chambers, and one end of the battery cover is hinged to the spray host.

[0015] The beneficial effects of this utility model are as follows: This utility model provides a sprayer that can use battery packs with different voltages. By setting a limit switching component between at least two battery chambers, a linkage limit function based on the battery insertion state is realized. That is, when one battery chamber is inserted into the battery pack, the limit switching component structure changes position and protrudes into the adjacent battery chamber, thereby preventing the other battery pack from being inserted at the same time. This avoids electrical faults caused by voltage mismatch due to user misoperation and significantly improves the safety and system compatibility of the sprayer. Attached Figure Description

[0023] 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.

[0024] 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.

[0025] The specific implementation of the anti-misinsertion structure for the battery pack of an electric sprayer according to this utility model is as follows:

[0026] The present invention provides a battery pack 6 anti-misinsertion structure for an electric sprayer, which is mainly used in spraying equipment with multiple battery power supply requirements, and is especially suitable for electric sprayers that allow the use of battery packs 6 with different voltage levels.

[0027] This structure, through a mechanically linked limit switching device, prevents users from accidentally inserting multiple battery packs 6 of different voltages into the device at the same time, thereby effectively avoiding electrical faults that may be caused by voltage mismatch.

[0028] Specifically, the structure includes a spray host 1, and the spray host 1 has at least two battery chambers inside its housing for accommodating battery packs 6 of different voltage levels.

[0029] The internal structure of the battery compartment is adapted to the shape of the battery pack 6 and is equipped with electrical connection terminals to ensure a stable electrical connection between the battery and the internal circuitry of the spray unit 1 after insertion. The battery compartment not only meets the different power requirements of the sprayer but also improves the flexibility of battery pack 6 installation.

[0030] A limiting switch 5 is provided between the two battery chambers. This limiting switch 5 is rotatably mounted within the mounting cavity of the spray host 1. Its structure is designed with two limiting surfaces, each facing one of the two battery chambers. The limiting switch 5 is mounted on the host housing structure via rotating shafts 53 at both ends, allowing it to rotate around the shafts 53. To ensure that the limiting switch 5 automatically returns to its original position or maintains a stable limiting state after rotation, a torsion spring is fitted onto the rotating shafts 53.

[0031] The rebound force or positioning force generated by the torsion spring is used to control the rotation direction and angle of the limit switching component 5, thereby enhancing the stability of the limit function.

[0032] In the two limiting surfaces of the limiting switching component 5, the first limiting surface 51 and the second limiting surface 52 are set perpendicular to each other, forming an L-shaped structure, so that they can protrude from the interior of a certain battery cavity after rotation.

[0033] When a user inserts a battery pack 6 into the first battery cavity 4, the limiting switch 5 rotates to one side under the pushing action of the battery pack 6, and the limiting surface on the opposite side protrudes into the second battery cavity 3, thereby forming a mechanical limit to prevent the user from continuing to insert the battery pack 6 into the second battery cavity 3.

[0034] Conversely, when the user inserts the battery pack 6 into the second battery chamber 3, the limit switching component 5 also rotates, causing the limiting surface at the first battery chamber 4 to protrude, forming a limiting action in the opposite direction. Through this structural linkage design, the interlocking state between the two battery chambers can be achieved, that is, only one battery chamber is allowed to be in the battery-insertable state at any time, ensuring that the spray host 1 can only be connected to a battery pack 6 of one voltage level, thereby avoiding the risks caused by voltage inconsistency.

[0035] The mounting cavity structure containing the limit switch 5 is located between the two battery cavities and provides mounting space for the limit switch as a rotation support. This mounting cavity is designed as a closed or semi-closed structure, and has bearing grooves or fixing holes inside to stabilize the rotating shaft 53 of the limit switch. The entire mounting structure is made of high-strength plastic or metal to ensure sufficient mechanical strength and wear resistance during long-term use.

[0036] In addition, to further enhance the safety and ease of use of the equipment, each battery compartment is equipped with a battery cover 2 to protect the battery compartment from foreign objects and dust contamination when not in operation. One end of the battery cover 2 is mounted on the housing of the spray host 1 via a hinged structure, allowing the user to easily open or close the cover. The cover can be equipped with a snap-fit ​​or magnetic structure for automatic closure and stable fixation, ensuring that the battery does not loosen or fall off under vibration conditions.

[0037] The battery pack anti-misinsertion structure of this utility model for electric sprayers achieves intelligent limit control through structural linkage. Without relying on an electronic control system, it can effectively prevent misoperation through mechanical structure alone, significantly improving the safety and system compatibility of spraying equipment and possessing broad practical 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.
