Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a fan with an optional rechargeable battery. Background Technology

[0002] In daily life, electric fans are a widely used household appliance, providing a cool and comfortable environment for people in hot weather. However, in some countries or regions with unstable mains power supply, the normal use of electric fans is greatly limited. For example, in some places, aging power grid facilities, insufficient power supply, or uneven power distribution frequently occur, resulting in frequent fluctuations in mains voltage and prolonged power outages. In such situations, electric fans cannot be directly powered by mains electricity for a stable supply, and their normal operation is severely affected, failing to meet people's need for continuous cooling.

[0003] To address these issues, some electric fans with built-in backup power supplies have appeared on the market. However, most of these backup power supplies use built-in batteries, which have several drawbacks. For example, the capacity of built-in batteries is limited and cannot meet the needs of long-term use; replacing the battery requires disassembling the internal structure of the fan, which is complicated and can easily damage the fan; furthermore, the charging method for built-in batteries is not flexible enough, usually requiring the fan to be connected to AC power for charging, and it cannot achieve portable charging or fast charging.

[0004] Therefore, a new technical solution is needed that can provide stable power support for electric fans when the mains power supply is unstable, and has flexible charging methods and convenient battery replacement function to meet the needs of different users. Utility Model Content

[0013] Furthermore, a third connector is connected to the other end of the power supply line away from the first connector, and the third connector is electrically connected to the rechargeable battery.

[0014] The beneficial effects of this utility model include:

[0015] Fans equipped with optional rechargeable batteries can be powered by mains electricity or by the rechargeable battery when mains power is unstable or during power outages, greatly improving the fan's adaptability and reliability in different environments. Furthermore, the rechargeable battery power supply allows the fan to be used normally in scenarios without mains power (such as outdoors or during power outages), expanding the fan's application range. In addition, combining the rechargeable battery with the power cord and mains plug avoids a complex built-in battery structure, reducing manufacturing costs and facilitating maintenance and replacement.

These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0024] Reference Figures 1 to 3 In some embodiments, the present invention discloses a fan with an optional rechargeable battery, which includes a fan body 100, a rechargeable battery 200, a power supply line 300, and a mains plug 210.

[0025] The fan body 100 is the main structural part of the fan, used to generate airflow and bring cool air to the user. The fan body 100 includes a fan head 120 and a mounting base 130. The fan head 120 is connected to the mounting base 130 by a hinge, allowing the fan head 120 to be flexibly adjusted in angle to meet different user needs. A power supply interface 110 is provided at the bottom of the mounting base 130, facing the ground for easy connection to the power supply cable 300. Below the power supply interface 110 is a groove 111 that partially matches the shape of the first connector 310, so that the first connector 310 is fixed in the groove 111, making the first connector less prone to damage.

[0026] Reference Figure 3As shown, the rechargeable battery 200 provides power to the fan, allowing it to operate normally without mains power. The rechargeable battery 200 can be a lithium-ion battery or a lead-acid battery. Lithium-ion batteries offer advantages such as small size, light weight, and fast charging speed, making them suitable for users with high portability requirements. Lead-acid batteries, on the other hand, are characterized by lower cost and higher reliability, making them suitable for cost-sensitive users. The rechargeable battery 200 is electrically connected to the mains plug 210 via the power supply cable 300. When mains power is available, the rechargeable battery 200 can be charged through the mains plug 210, providing convenience and speed.

[0027] The power supply cable 300 transmits power from the rechargeable battery 200 to the fan body 100, enabling the fan to operate normally. A first connector 310 is provided at the end of the power supply cable 300. The first connector 310 is detachably connected to the power supply interface 110, allowing users to easily replace the rechargeable battery 200 as needed, thus improving the fan's operational flexibility. Furthermore, a third connector 330 is connected to the other end of the power supply cable 300 away from the first connector 310. The third connector 330 is electrically connected to the rechargeable battery 200, further ensuring the stability and reliability of power transmission.

[0028] To improve the ease of use of the fan, this embodiment also includes a telescopic rod 400. One end of the telescopic rod 400 is inserted into the bottom end of the mounting base 130, and the power supply interface 110 is disposed adjacent to the main body of the telescopic rod 400. The design of the telescopic rod 400 allows the height of the fan to be adjusted according to the user's needs. The user can adjust the fan to the most comfortable height according to their height and usage scenario, thus improving the user's comfort. The mounting base 130 has a mounting groove that matches the shape of the power supply interface 110. This design allows the power supply interface 110 to be securely installed in the mounting base 130, further improving the overall structural stability of the fan.

[0029] The AC power plug 210 is connected to the second connector 320 via the power supply cable 300, and the second connector 320 is electrically connected to the rechargeable battery 200. The second connector 320 allows the rechargeable battery 200 to be connected to the AC power plug 210 more conveniently, enabling fast charging, improving charging efficiency, and reducing user waiting time.

[0030] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
