Description

Technical Field

[0001] This utility model relates to the field of charging device technology, and in particular to a DC converter head hanger charging device. Background Technology

[0002] A handheld vacuum cleaner is a lightweight and portable cleaning tool designed to meet the diverse cleaning needs of modern families. Its compact size and light weight make it easy to operate and carry, especially suitable for cleaning hard-to-reach areas such as sofas, car interiors, corners, and stairs. Handheld vacuum cleaners are typically cordless and equipped with high-performance rechargeable batteries, offering runtimes ranging from a few minutes to tens of minutes, sufficient for basic daily household cleaning needs. They possess powerful suction and come with various attachments, such as crevice tools and brush heads, easily handling common debris like dust, crumbs, hair, and pet fur. Furthermore, many handheld vacuum cleaners feature a one-button dustbin emptying function for added convenience and hygiene. With continuous technological advancements, the performance and battery life of handheld vacuum cleaners are constantly improving, with some high-end models also equipped with intelligent sensing technology that automatically adjusts suction power based on the cleaning environment, achieving both energy efficiency and high performance.

[0003] Traditional charging methods for handheld vacuum cleaners have many inconveniences, such as messy and tangled charging cables, and the need to rummage through storage corners to find the charger and plug it in each time, which is cumbersome and inconvenient. Wall-mounted charging, on the other hand, integrates charging and storage functions. Simply hang the vacuum cleaner on the wall and pull out the charging connector on the vacuum cleaner to charge, avoiding the problem of losing the charger. However, when the vacuum cleaner is mounted on the wall, its center of gravity is unstable, and if it is not restrained, it is easy for it to fall.

[0004] Therefore, a DC converter head hanger charging device is proposed to solve or alleviate the above problems. Utility Model Content

The base shell 1 is detachably connected to a base 5, and when the base shell 1 and base 5 are detachably connected, the base 5 is electrically connected to the base shell 1. A hanging cover 10 that abuts against the outer ring of the connecting cylinder 3 is fixedly connected to the base 5. A receiving space for accommodating a hanging bracket is formed between the hanging cover 10, the connecting cylinder 3, and the front handle 4. Two sets of front limiting covers 7 and two sets of rear limiting covers 6, which can be fitted onto both sides of the base shell 1, are fixedly connected to the base 5. The front limiting covers 7 and the rear limiting covers 6... A front limiting block 15 and a rear limiting block 14 are fixedly connected to one side of the base shell 1. The base shell 1 has a front limiting groove 13 for accommodating the front limiting block 15 and a rear limiting groove 12 for accommodating the rear limiting block 14. Guide slopes are provided at both ends of the front limiting block 15 and the rear limiting block 14 along the length of the base shell 1. A rear wiring hole 11 is provided on the base 5. A front wiring hole 8 communicating with the rear wiring hole 11 is provided on the base shell 1. A receiving groove is provided on the front of the base 5. A cover 9 that closes the receiving groove is detachably connected to the base 5 located at the receiving groove. A charging cable is placed in the receiving groove.

[0029] like Figure 4 As shown, an electromagnet 23 is installed inside the mounting housing 10, a metal sheet is installed inside the connecting cylinder 3, and a battery 21 is installed inside the bottom housing 1. When the battery 21 is charging, the electromagnet 23 is energized; when the battery 21 is de-energized, the electromagnet 23 can be switched on and off. The system also includes a mounting bracket circuit, which includes a fuse 16, a rectifier bridge 17, a filter capacitor 18, a DC converter 19, a charging management chip 20, a relay control circuit 24, a relay 25, and a push-button switch 22. One end of the fuse 16 is electrically connected to the mains power, and the other end is electrically connected to the input terminal of the rectifier bridge 17. The other end of the rectifier bridge 17 is electrically connected to the filter capacitor 18. The other end of the filter capacitor 18 is electrically connected to the input terminal of the relay control circuit 24, and the output terminal of the relay control circuit 24 is electrically connected to the relay 25. Relay 25 is electrically connected to electromagnet 23 and then grounded. The other end of filter capacitor 18 is electrically connected to battery 21 through DC converter 19. The input terminal of charging management chip 20 is electrically connected to battery 21. Battery 21 is electrically connected to electromagnet 23 through push button switch 22 and then grounded. Charging management chip 20 is electrically connected to the controlled terminal of relay control circuit 24. Relay control circuit 24 includes a transistor switch. The base, collector, and emitter of the transistor switch are the controlled terminal, input terminal, and output terminal, respectively. Charging management chip 20 includes a TP4056 chip. When battery 21 is charging, TP4056 chip outputs a high-level signal to relay control circuit 24. When battery 21 is finished charging, TP4056 chip outputs a low-level signal to relay control circuit 24.

[0030] In practical application, the user can hold the entire vacuum cleaner in their hand by gripping the rear handle 2, so as to pick it up and move it. During this process, the base 5 is sleeved on the outside of the bottom shell 1 through the front limiting shell 7 and the rear limiting shell 6. The front limiting block 15 and the rear limiting block 14 on the front limiting shell 7 and the rear limiting shell 6 are embedded in the front limiting groove 13 and the rear limiting groove 12 on the bottom shell 1, which has a certain limiting effect on the base 5 on the bottom shell 1.

[0031] When hanging and charging the vacuum cleaner, the base 5 can be manually detached from the bottom shell 1. The guide ramps on the front and rear limit blocks 15 and 14 allow them to disengage from the front and rear limit grooves 13 and 12. The front handle 4 and connecting tube 3 are then hung on the hanger, and the base 5 is reinstalled on the bottom shell 1. The hanger is now positioned within the space formed by the hanging cover 10, connecting tube 3, and front handle 4, which helps to restrict the vacuum cleaner's charging action. To prevent the bottom shell 1 from detaching from the base 5 due to the vacuum cleaner's weight, the user needs to charge the vacuum cleaner promptly by opening the cover 9 and removing the charging cable. The battery 21 is charged by mains power. Under the action of rectifier bridge 17, filter capacitor 18, and DC converter 19, the battery 21 is charged with constant current and voltage. During this process, the charging management chip 20 outputs a high-level signal to the controlled terminal of the relay control circuit 24. At this time, the relay 25 is turned on, so that the electromagnet 23 can be energized. The electromagnet 23 generates a magnetic force on the metal sheet in the connecting cylinder 3, which makes it difficult for the base 5 to detach from the bottom shell 1. After the charging is completed, the signal output by the charging management chip 20 is low-level, which causes the relay control circuit 24 to control the relay 25 to be de-energized, and the electromagnet 23 is also de-energized. If it is necessary to keep the electromagnet 23 energized, the power supply between the battery 21 and the electromagnet 23 can be controlled by the push button switch 22.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
