[0002] In existing home appliance technology, to improve safety during use, anti-tipping mechanisms are often incorporated to automatically cut off power in the event of accidental tilting or tipping. However, most existing anti-tipping mechanisms are located inside the appliance itself. When the appliance is operating, especially when it has a tilting or rotating function, this structure is easily affected by the appliance's own rotational movement, which may misinterpret it as a tipping over, leading to frequent false stops and disrupting normal use. Utility Model Content

[0003] In order to overcome the defects of the prior art, the anti-tipping mechanism and its ventilation equipment of this utility model can effectively avoid accidental triggering caused by rotation when the equipment is in normal swinging or rotating operation. When the support frame is tilted and rotated, it will drive the anti-tipping component to act, thereby cutting off the power supply line, shutting down the equipment in time, and avoiding the use risks caused by tilting.

The support frame includes a first connector rotatably connected to one end of the machine body and a second connector rotatably connected to the other end of the machine body. The anti-tipping component is connected to the first connector or the second connector.

[0009] When the support frame rotates and tilts, the anti-tipping component can be rotated through the first connector or the second connector to cut off the power supply to the power line and stop the household equipment from working.

[0011] Furthermore, the machine body is provided with a connecting seat, the connecting seat is provided with a limiting hole, one side of the connecting bracket is provided with a rotating column that cooperates with the limiting hole, and the other side is provided with a connecting column. The anti-tipping component is fixedly connected to the connecting column and located inside the machine body.

[0012] The rotating column passes through the limiting hole, and when the support frame rotates, it can drive the rotating column to rotate within the limiting hole, thereby driving the anti-tipping component to rotate.

[0013] Furthermore, the connecting seat is also provided with a rotating shaft, and the connecting bracket is provided with a rotating sleeve that is rotatably connected to the rotating shaft.

[0014] Furthermore, the anti-tipping component adopts an electronic anti-tipping switch or a mechanical anti-tipping switch.

[0022] 1. The anti-tipping mechanism and ventilation equipment of this utility model, when the equipment is in normal swing or rotation operation, can effectively avoid accidental triggering caused by rotation because the anti-tipping component is connected to the support frame; when the support frame tilts and rotates, it will drive the anti-tipping component to act, realize the power supply line cut-off, shut down the equipment in time, and avoid the use risks caused by tilting.

[0023] 2. The anti-tipping mechanism and ventilation equipment of this utility model are designed with the anti-tipping component mounted on the support frame.

[0033] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Example 1

[0037] like Figure 1-3 The diagram illustrates an anti-tipping mechanism for a household appliance equipped with a power supply cord. The anti-tipping mechanism includes a body 1, a support frame 2, and an anti-tipping component 4 electrically connected to the power supply cord. The support frame 2 is rotatably connected to the body 1, supporting the appliance and providing rotational support. Specifically, the support frame 2 includes a first connector 22 and a second connector 23 rotatably connected to both ends of the body 1. The anti-tipping component 4 is mounted on either the first connector 22 or the second connector 23.

[0038] When the support frame 2 tilts as a whole, the first connecting piece 22 or the second connecting piece 23 rotates accordingly, causing the anti-tipping component 4 to rotate as well. This disconnects the power supply, achieving automatic power-off protection for the household appliance and effectively preventing electrical safety hazards caused by accidental tipping. Since the anti-tipping component 4 is mounted on the support frame 2, it avoids misjudgments caused by machine movement during normal oscillation or rotation, thus significantly improving the accuracy of anti-tipping judgment and the reliability of equipment operation.

[0039] Furthermore, the anti-tipping mechanism also includes a connecting bracket 3, which is fixedly connected to the first connecting member 22 or the second connecting member 23, and the anti-tipping component 4 is fixedly mounted on the connecting bracket 3 to facilitate the structural arrangement and the transmission of component movements.

[0040] Preferably, the body 1 is provided with a connecting seat 15, the connecting seat 15 having a limiting hole 151, one side of the connecting bracket 3 having a rotating column 31 that mates with the limiting hole 151, and the other side having a connecting column 33, the anti-tipping component 4 being installed on the connecting column 33 and located inside the body 1. The rotating column 31 passes through the limiting hole 151 and can rotate within it, used to transmit the tilting action of the support frame 2 to the anti-tipping component 4; at the same time, the limiting hole 151 limits the rotation range of the rotating column 31, preventing the support frame 2 from rotating excessively.

[0041] It should be noted that the body 1 is also provided with a connecting shaft 16. When the connecting bracket 3 is connected to the first connecting member 22, the second connecting member 23 is rotatably connected to the connecting shaft 16; or when the connecting bracket 3 is connected to the second connecting member 23, the first connecting member 22 is rotatably connected to the connecting shaft 16.

[0042] In addition, the connecting seat 15 is also provided with a rotating shaft 152, and the connecting bracket 3 is provided with a rotating sleeve 32 that can rotate with the rotating shaft 152 to enhance the rotational support effect of the connecting bracket 3, thereby making the entire transmission process smoother and the action response more reliable.

[0043] The anti-tipping component 4 can be an electronic or mechanical anti-tipping switch. The mechanical anti-tipping switch includes a switch 41 electrically connected to the power supply line and an actuating element 42 that cooperates with the switch 41. When the support frame 2 tilts and causes the anti-tipping component 4 to rotate, the actuating element 42 contacts and is pressed against the switch 41, triggering the switch 41 to disconnect the power supply line. This achieves automatic power-off control of the household equipment, providing an immediate and reliable safety response and significantly improving the equipment's protection capabilities in abnormal conditions.

[0044] It should be noted that the actuator 42 has a cavity inside, in which a ball and a lever structure are installed. One end of the lever has a tray, and the other end serves as a fulcrum for rotation, with its lower end in contact with the switch 41. Under normal conditions, the ball is above the tray. When the anti-tipping component 4 rotates, the ball slides due to gravity and presses against the tray, driving the lever to rotate around its fulcrum. This causes the bottom of the lever to press the switch 41, thereby disconnecting the circuit.

[0045] Furthermore, the support frame 2 also includes a support base 21, a first connector 22 connected to one end of the support base 21, and a second connector 23 connected to the other end of the support base 21, so as to improve the overall stability and anti-tilting ability of the support structure.

[0046] Example 2

[0047] like Figure 1-6The ventilation device shown includes the anti-tipping mechanism in the first embodiment above, which includes a body 1, a fan 6, a heating element 5, and a power switch 17 connected to a power supply line; wherein the fan 6 and the heating element 5 are both electrically connected to the power supply line, and the on / off state is controlled by the anti-tipping component 4 to ensure safe operation.

[0048] Preferably, the body 1 has an air inlet 13 on one side, the heating element 5 is located at the air inlet 13, and the fan 6 is mounted on the heating element 5 with its air inlet facing the heating element 5, so that the airflow is heated by the heating element 5 during the intake process, thereby improving the air handling efficiency.

[0049] The air inlet 13 is equipped with a dust filter 14 to filter particulate impurities in the incoming airflow and protect the internal components from dust accumulation. An air outlet 11 is located on the other side of the unit 1, with the air outlet of the fan 6 facing this outlet 11. The outlet 11 is equipped with a protective mesh 12 to prevent foreign objects from entering the equipment and to improve safety during operation.

[0050] Through the above structural design, this utility model not only effectively improves the anti-tipping protection capability of the equipment and avoids unnecessary shutdowns caused by accidental triggering, but also achieves significant optimization in terms of safety and reliability, and has good prospects for practical application.

[0051] In other embodiments, this anti-tipping mechanism is also applicable to household appliances with stability requirements, such as air purifiers, electric heaters, and electric fans. By integrating the anti-tipping mechanism into the support structure of these devices, the power supply circuit can be quickly cut off and operation terminated promptly when the device tipps over, thereby effectively reducing safety hazards such as electric shock and fire that may be caused by the device tipping over, and further improving the safety and reliability of household appliances.

[0052] In summary, the anti-tipping mechanism and ventilation equipment of this utility model can effectively prevent accidental triggering caused by rotation when the equipment is in normal swinging or rotating operation. However, when the support frame 2 tilts and rotates, it will drive the anti-tipping component 4 to operate, thereby cutting off the power supply line, shutting down the equipment in time, and avoiding the use risks caused by tilting.

[0053] The present invention relates to an anti-tipping mechanism and its ventilation equipment, wherein the anti-tipping component 4 is mounted on the support frame 2, so that it responds to the actual tilting state of the support structure. When the support frame 2 tilts as a whole, the anti-tipping component 4 can accurately sense it and control the equipment to stop running, thereby effectively avoiding misjudgment caused by the rotation of the equipment.

[0054] This utility model relates to an anti-tipping mechanism and its ventilation equipment. While improving the safety of equipment operation, the structure also takes into account the ability to prevent misjudgment and the sensitivity of the protection response. It enhances the stability and practicality of the ventilation equipment in multi-angle swing and unstable use scenarios, and has high application value.

[0055] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

[0056] It should be understood that the terms "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0057] Furthermore, in the description of this utility model, "multiple" and "several" mean two or more, unless otherwise explicitly specified.

[0058] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
