Description

Technical Field

[0001] This utility model relates to the field of portable fan technology, and in particular to a portable high-power fan with a dual-battery switching system. Background Technology

[0002] In daily life and many outdoor and temporary work scenarios, portable high-powered fans have become an important tool for people to cope with heat and improve local environments due to their compact size, portability, and ability to provide strong airflow. However, traditional portable high-powered fans have significant shortcomings in terms of power supply and battery switching, which seriously restricts their user experience and scope of application.

[0003] Currently, most portable high-powered fans on the market use a single battery power supply. A single battery has a limited capacity and will quickly deplete during continuous use. Once the battery is low, the fan will stop working, forcing users to interrupt their current activity to replace the battery or find charging equipment. In outdoor environments, such as camping or mountaineering, charging facilities are scarce, and the number of spare batteries carried is also limited. This severely restricts the usage time of single-battery fans, failing to meet users' needs for extended use. For example, during long outdoor hikes in the hot summer, a single-battery fan may only last for a few hours, after which hikers must endure the sweltering heat, significantly impacting the comfort and experience of outdoor activities.

[0004] While some portable high-powered fans equipped with dual batteries alleviate battery life issues to some extent, they have several shortcomings in battery switching methods. Some products use simple mechanical switches for battery switching, which is not convenient and requires users to spend time and effort to operate the switch accurately. In addition, some products use complex electronic circuits to achieve battery switching. Although automatic switching is possible, the complex circuit structure increases the product cost and failure rate. Complex electronic circuits are also susceptible to external environmental factors such as temperature, humidity, and electromagnetic interference, which can lead to switching failures or incorrect switching, affecting the normal operation of the fan. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a portable high-power fan with a dual-battery switching system to solve the problems of short battery life and inconvenient battery switching of existing portable fans.

[0006] To achieve the above objectives, this utility model provides a portable high-power fan with a dual-battery switching system, comprising: a mounting shell, a groove on one side of the mounting shell, a fan head rotating within the groove, a power socket on one side of the mounting shell, and a switch on the other side of the mounting shell;

[0007] A switching component, which is installed inside the mounting housing, is used to switch circuits;

[0008] A locking component is mounted on one side of the mounting housing and is used to lock and unlock the switching component.

[0009] Preferably, a circuit board is installed inside the mounting housing, and the plug slot and the switch are electrically connected to one side of the circuit board. Two battery bodies and contact plates are respectively installed inside the mounting housing. One of the contact plates abuts against one side of the circuit board and its other side abuts against one side of the battery body. One side of the other contact plate abuts against one side of the battery body. Two battery bodies are installed between the two circuit boards.

[0010] Preferably, the switching assembly includes a trigger rod slidably mounted on one side of the mounting housing. A plurality of sliding grooves are provided on one side of the mounting housing. A plurality of insulating plates are fixedly mounted on both sides of the trigger rod. A trigger plate is installed between each of the two insulating plates on both sides of the trigger rod. The two sides of the trigger plate abut against one side of the circuit board and the battery body, respectively.

[0011] Preferably, the locking assembly includes a first limiting shell fixedly installed on one side of the mounting shell, a second limiting shell fixedly installed on one side of the first limiting shell, a limiting groove formed in the first limiting shell, a plurality of lock heads slidably installed on one side of the second limiting shell, a button fixedly installed on one side of the lock head, sliders fixedly installed on the symmetrical sides of the trigger rod, a lock hole formed on the slider, and the lock head being adapted to the lock hole.

[0012] Preferably, the first limiting shell has a plurality of sliding grooves, and the slider is slidably installed in the sliding grooves.

[0013] Preferably, the second limiting shell has an installation groove, and a plurality of return springs are installed in the installation groove. The return springs are sleeved on the lock head, one side of the return spring is fixedly installed on one side of the installation groove, and the other side of the return spring is fixedly installed on one side of the button.

[0014] Preferably, the lock head passes through the mounting groove and extends into the limiting groove.

[0015] The beneficial effects of this utility model are:

[0016] 1. This portable high-powered fan with a dual-battery switching system enables convenient switching between two batteries by incorporating a switching component. When one battery is low on power, the system can quickly switch to the other battery without interrupting fan operation, effectively improving the fan's battery life and ensuring continuous and stable use. This avoids the interruptions caused by frequent battery replacements or charging required by traditional single-battery portable fans, resulting in a better user experience. Furthermore, the switching component has a simple structure, is easy to operate, safe and reliable, and possesses high practical value.

[0017] 2. This portable high-powered fan with a dual-battery switching system features a locking component that reliably locks the switching component. When the user does not operate the switching mechanism, the locking component, under the action of a return spring, automatically inserts the lock head into the locking hole of the slider, fixing the trigger rod in a predetermined position. This prevents the trigger rod from sliding due to external force or vibration, which could lead to abnormal circuit connections and ensures the stability and safety of the switching component during operation. Furthermore, when the user needs to switch batteries, they can simply pull a button to unlock the system. The operation is simple, and the locking and unlocking functions smoothly, improving the user experience and ensuring the accuracy of battery switching and the reliability of the fan's power supply.

[0029] like Figures 1 to 6 As shown, a portable high-powered fan with a dual-battery switching system includes: a mounting housing 1, a groove 4 on one side of the mounting housing 1, a fan head 3 rotating within the groove 4, a power socket 5 on one side of the mounting housing 1, and a switch 2 on the other side of the mounting housing 1; a switching assembly installed inside the mounting housing 1, used for switching circuits; and a locking assembly installed on one side of the mounting housing 1, used for locking and unlocking the switching assembly; a circuit board 13 installed inside the mounting housing 1, the power socket 5 and the switch 2 being electrically connected to one side of the circuit board 13; two contact plates 15 installed inside the mounting housing 1, one of which abuts against one side of the circuit board 13 and the other side of which abuts against one side of the battery body 14, and the other contact plate 15 abuts against one side of the battery body 14; and two battery bodies 14 are installed between the two circuit boards 13.

[0030] This portable high-powered fan with a dual-battery switching system features two contact plates 15 inside the mounting housing 1, with two battery bodies 14 installed between them. When the user needs to switch battery power, the switching component can be unlocked via a locking mechanism. Once unlocked, the switching component switches the circuit, electrically connecting one battery body 14 to the contact plate 15 while the other battery body 14 remains in standby mode, ensuring continuous fan operation. When the current battery body 14 is low on power, the user can operate the locking mechanism again to unlock the switching component, switching the circuit to the other battery body 14 for power without interrupting use, thus improving the fan's battery life and portability. A power socket 5 on one side of the mounting housing 1 can charge the battery body 14 or directly power it when connected to an external power source, while a switch 2 on the other side controls the fan head 3 to start and stop. The overall structure is compact, and the switching operation is convenient.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, the switching assembly includes a trigger rod 7 that is slidably mounted on one side of the mounting housing 1. Several grooves 8 are provided on one side of the mounting housing 1. Several insulating plates 12 are fixedly mounted on both sides of the trigger rod 7. A trigger piece 11 is installed between the two insulating plates 12 on both sides of the trigger rod 7. The two sides of the trigger piece 11 abut against one side of the circuit board 13 and the battery body 14, respectively.

[0032] The switching component of this device achieves circuit switching by sliding the trigger rod 7. The trigger rod 7 is slidably installed on one side of the mounting housing 1. Several grooves 8 are opened on one side of the mounting housing 1, and the trigger rod 7 can slide along the grooves 8. When the user pushes the trigger rod 7, several insulating plates 12 fixedly installed on both sides of the trigger rod 7 move accordingly, causing the position of the trigger piece 11 installed between the insulating plates 12 to change. The two sides of the trigger piece 11 respectively abut against one side of the circuit board 13 and the battery body 14. By sliding and changing the contact position between the trigger piece 11 and different battery bodies 14, the electrical connection between different battery bodies 14 and the circuit board 13 is switched, realizing the power supply switching of dual batteries. The operation is simple and the switching is stable and reliable.

[0033] like Figure 2 , Figure 5 , Figure 6As shown, the locking assembly includes a first limiting shell 6 fixedly installed on one side of the mounting shell 1, a second limiting shell 10 fixedly installed on one side of the first limiting shell 6, a limiting groove 16 formed in the first limiting shell 6, a plurality of lock heads 17 slidably installed on one side of the second limiting shell 10, a button 9 fixedly installed on one side of the lock head 17, sliders 22 fixedly installed on both sides of the trigger rod 7, and lock holes 21 formed on the sliders 22, with the lock heads 17 matching the lock holes 21; a plurality of sliding grooves 20 formed in the first limiting shell 6, with the sliders 22 slidably installed in the sliding grooves 20; a mounting groove 19 formed in the second limiting shell 10, with a plurality of return springs 18 installed in the mounting groove 19, the return springs 18 sleeved on the lock heads 17, one side of the return springs 18 fixedly installed on one side of the mounting groove 19, and the other side of the return springs 18 fixedly installed on one side of the button 9; the lock heads 17 penetrate the mounting groove 19 and extend into the limiting groove 16;

[0034] When the user needs to switch the power supply of the battery body 14, the button 9 can be pulled outward first. The button 9 drives the lock head 17, which is fixedly connected to it, to move outward against the elastic force of the reset spring 18, so that the lock head 17 is pulled out from the lock hole 21 on the slider 22, releasing the lock on the slider 22. At this time, the sliders 22 fixed on both sides of the trigger rod 7 can slide freely in the sliding groove 20 in the first limiting shell 6, driving the trigger rod 7 to slide in the limiting groove 16. During the sliding of the trigger rod 7, the position of the trigger piece 11 fixed between the insulating plates 12 on both sides of it changes accordingly, so that the trigger piece 11 is connected to different battery bodies 14 and circuit boards 13, thereby realizing the switching of different battery bodies 14 and circuits. When the user releases the button 9, the elastic force of the reset spring 18 without external force will cause the lock head 17 to automatically reset and insert into the lock hole 21 on the slider 22, re-locking the slider 22 and the trigger rod 7, ensuring that the switching component maintains a stable position during use, preventing the switching position from shifting due to external force or vibration, and ensuring the safety and reliability of the circuit connection.
