Description

Technical Field

[0001] The invention relates to the technical field of tipping protection switches, and in particular to a tipping switch with multi-directional protection. Background Art

[0002] Currently in the home appliance industry, in order to prevent home appliances from tipping over, tip-over protection switches are designed on home appliances. However, conventional tip-over protection switches can only provide one-way tip-over protection or two-way tip-over protection. Once applied to specific scenarios, they will have certain limitations and cannot meet the increasingly diverse appearance designs of home appliances. Therefore, it is necessary to design a tip-over switch installed on the device to achieve multi-angle tip-over protection of the device. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a tipping switch with multi-directional protection, which adopts the principle of reed switch induction magnetic field to trigger action and output an on or off signal, so that the device installed with the tipping switch can immediately cut off power and sound an alarm when it tips over. The spherical magnet is combined with a cavity with a fan-shaped cross-section to make it have a tipping angle sensitive characteristic, so that the tipping situations in multiple directions can be identified at the same time to protect the device.

[0004] In order to achieve the above objectives, the technical solution adopted by the present invention is:

[0005] A multi-directional protection tipping switch comprises a shell, wherein two parallel arc partitions are arranged in the shell, and the arc partitions divide the shell into a first cavity, a second cavity and a third cavity from top to bottom, the diameter of the first cavity is smaller than the diameters of the second cavity and the third cavity, and a reed switch is installed in the middle of the first cavity, the diameters of the second cavity and the third cavity are the same, and a spherical magnet is movably connected in the second cavity, a base is installed in the middle of the third cavity, a base magnet is installed on the base, and the N pole and S pole of the base magnet are respectively distributed on the upper and lower sides thereof.

[0006] As a further solution of the present invention: the tipping switch also includes a connector, which is arranged just above the housing and is connected to the two magnetic reed sheets of the reed switch through wires.

[0007] As a further solution of the present invention: the connector is electrically connected to the device power supply and the external alarm.

[0008] As a further solution of the present invention: the horizontal cross-sections of the first cavity, the second cavity and the third cavity of the shell are all circular.

[0009] As a further solution of the present invention: the middle vertical section of the second cavity is a fan-shaped section, and the middle position of the fan-shaped section is the lowest position of the second cavity.

[0010] As a further solution of the present invention: the housing is provided with mounting plates for mounting on the device on both sides of the connection between the second cavity and the third cavity, and the mounting plates are provided with mounting holes.

[0011] Compared with the prior art, the present invention has the following beneficial effects: when the shell is in a non-tilted state, the spherical magnet is in the middle of the second cavity, so that the spherical magnet, the reed switch and the base magnet are on the same center line, so that the magnetic field between the spherical magnet and the base magnet triggers the reed switch to act and transmits the on or off signal to the connector to control the device, wherein the device is kept powered on and disconnected from the alarm device, and when the shell falls with the device, the spherical magnet rolls to the two sides of the second cavity under the action of its own gravity, so that the magnetic field acting on the reed switch disappears, and the reed switch is disconnected Or the connection signal is transmitted to the connector to control the device, wherein the power-on state is changed to the power-off state, and the disconnection alarm is changed to the connection alarm, so that the device automatically cuts off the power and sounds an alarm when the housing follows the device to fall over, wherein the device can remain powered on as long as the spherical magnet is maintained at the lowest position in the middle of the second cavity, and the spherical magnet rolls at any position in the second cavity by its own gravity, that is, when the device falls in any direction, the device can be powered off and an alarm can be sounded as long as the spherical magnet is away from the reed switch, thereby simultaneously identifying the tipping situations in multiple directions to protect the device, and has a wide range of applicability.

[0017] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions and beneficial effects of the present invention clearer and more specific.

[0018] like Figures 1 to 4As shown, the present embodiment provides a multi-directional protection tipping switch, including a shell 1, two parallel arc partitions 2 are arranged in the shell 1, and the arc partition 2 divides the shell 1 from top to bottom into a first cavity 101, a second cavity 102 and a third cavity 103, the diameter of the first cavity 101 is smaller than the diameters of the second cavity 102 and the third cavity 103, and a reed switch 3 is installed in the middle of the first cavity 101, the diameters of the second cavity 102 and the third cavity 103 are the same, and a spherical magnet 4 is movably connected in the second cavity 102, a base 5 is installed in the middle of the third cavity 103, a base magnet 6 is installed on the base 5, and the N pole and S pole of the base magnet 6 are respectively distributed on the upper and lower sides thereof.

[0019] In this embodiment, Figures 2 to 4 As shown, the tipping switch further includes a connector 7 , which is disposed directly above the housing 1 , and the connector 7 is connected to the two magnetic reed sheets of the reed switch 3 through wires 8 .

[0020] Specifically, when the device is in a non-tilted state, the magnetic field between the spherical magnet 4 and the base magnet 6 triggers the reed switch 3 and transmits the on or off signal to the connector 7; when the device is in a tilted state, the magnetic field acting on the reed switch 3 disappears, and the reed switch 3 transmits the off or on signal to the connector 7.

[0021] In this embodiment, the connector 7 is electrically connected to the device power supply and the external alarm.

[0022] Specifically, the power supply of the device and the external alarm are controlled by the connector 7, so as to switch between power on and power off, and switch between alarm off and alarm on.

[0023] In this embodiment, the horizontal cross-sections of the first cavity 101 , the second cavity 102 and the third cavity 103 of the housing 1 are all circular.

[0024] Specifically, the horizontal cross section of the second cavity 102 is designed to be circular, so that the spherical magnet 4 can roll freely in the second cavity 102 when the device is overturned.

[0025] In this embodiment, Figure 2 As shown, the middle vertical section of the second cavity 102 is a fan-shaped section, and the middle position of the fan-shaped section is the lowest position of the second cavity 102, so that the spherical magnet 4 is placed in the center of the second cavity 102 when in a non-tilted state, and is on the same center line as the reed switch 3 and the base magnet 6. A magnetic field is generated between the spherical magnet 4 and the base magnet 6, and the magnetic field triggers the reed switch 3.

[0026] In this embodiment, Figure 2As shown, the housing 1 is provided with mounting plates 9 for mounting on the device at both sides of the connection between the second cavity 102 and the third cavity 103 , and mounting holes 10 are opened on the mounting plates 9 .

[0027] like Figure 3 and Figure 4 As shown, the working principle of the multi-directional protection tipping switch of the present invention is: when the device is in a non-tilted state, the spherical magnet 4 is in the middle of the second cavity 102, so that the spherical magnet 4, the reed switch 3 and the base magnet 6 are on the same center line, so that the magnetic field between the spherical magnet 4 and the base magnet 6 triggers the reed switch 3 to operate and transmits the on or off signal to the connector 7 for device control, and the connector 7 keeps the device powered on and disconnected from the alarm device; when the device tilts in any direction, the spherical magnet 4 rolls in the same direction in the second cavity 102 under the action of its own gravity, so that the magnetic field acting on the reed switch 3 disappears, and the reed switch 3 disconnects or connects the signal The signal is transmitted to the connector 7 for device control, and the connector 7 changes the power on state to the power off state, and the off alarm state to the on alarm state, so that the device automatically powers off and sounds an alarm; in response to the alarm, the owner of the device puts the overturned device back to its original position, and the spherical magnet 4 returns to the middle of the second cavity 102, so that the spherical magnet 4, the reed switch 3, and the base magnet 6 are again on the same center line, so that the magnetic field is regenerated between the spherical magnet 4 and the base magnet 6, and the magnetic field causes the reed switch 3 to trigger the action again and transmit the disconnection or connection signal to the connector 7 for device control, and the connector 7 changes the power off state to the power on state, and the on alarm state to the off alarm state, so that the alarm is lifted and the device continues to work.

[0028] The above are only preferred specific implementations of this embodiment, but the protection scope of this embodiment is not limited to this. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and inventive concept of this embodiment within the technical scope disclosed in this embodiment, which should be covered by the protection scope of this embodiment.
