Description

Technical Field

[0001] The present invention relates to the technical field of switches, in particular to a release device that automatically pops open upon power failure. Background Art

[0002] Opening and closing mechanisms can be seen everywhere in people's lives, such as opening and closing windows, opening and closing doors, or opening and closing box covers. Generally, most of them are manual switches, but more advanced opening and closing mechanisms use electronic control mechanisms.

[0003] However, once the power is cut off, the electrically controlled opening and closing mechanism will fail, causing the opening and closing mechanism to be unable to open or close normally. When a danger occurs, such as a fire, the opening and closing mechanism will be in danger if it cannot open or close normally due to the power cut.

[0004] Therefore, there is an urgent need for a power-off automatic release device in the market to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a device that automatically pops open when the power is off, which is used to solve the technical problems existing in the above-mentioned prior art. When the power is off, the electromagnet body and the permanent magnet body repel each other, thereby opening the opening and closing mechanism to which they are connected.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a device that automatically pops open when the power is off, which is used to solve the technical problems existing in the above-mentioned prior art. When the power is off, the electromagnet body and the permanent magnet body repel each other, thereby opening the opening and closing mechanism to which they are connected.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-5 As shown, this embodiment provides a device 100 for automatically popping open when power is off, comprising an electric control assembly 1, an electromagnet assembly 2, and a permanent magnet assembly 4. The electric control assembly 1 is fixedly connected to the electromagnet assembly 2. The electromagnet assembly 2 is generally fixed to the fixed end of the opening and closing mechanism, and the permanent magnet body is fixed to the opening and closing end. (Taking a window as an example, the electromagnet assembly 2 is fixed to the window frame, and the permanent magnet assembly 4 is fixed to the movable window). The electromagnet assembly 2 includes an electromagnet body 22, and the permanent magnet assembly 4 includes a permanent magnet body. The electric control assembly 1 is also connected to a power supply, which can be a household power supply, that is, 220V AC power from a municipal circuit.

[0031] When the power supply is on, the electromagnet body 22 is de-energized, and the iron core in the electromagnet body 22 and the permanent magnet body are attracted to each other;

[0032] When the power is turned off, the electromagnet body 22 is energized, and the magnetic poles of the electromagnet body 22 are the same as those of the permanent magnet body.

[0033] During use, the electromagnet assembly 2 is mounted on the fixed end of the opening and closing mechanism (e.g., the window frame in the case of a window). The permanent magnet assembly 4 is then mounted on the movable end of the opening and closing mechanism (e.g., the movable window in the case of a window). When power is on, no current flows through the electromagnet body 22, causing the permanent magnet body and the iron core within the electromagnet body 22 to attract each other, thereby closing the window. When power is off, the electromagnet body 22 becomes charged and assumes the same magnetic pole as the permanent magnet body, generating a repulsive force between the two, opening the window.

[0034] In this embodiment, the working principle of the electronic control component 1 can be referred to Figure 5The electronic control component 1 also includes an electronic control box 12. The electronic control box 12 is a rectangular structure with a cavity inside. A circuit board 11 is fixed in the electronic control box 12 by a nylon column. The circuit board 11 is provided with wires, and the wires are connected to a power supply. The wires are provided with a non-polar step-down capacitor 13, a full-wave rectifier bridge 14 and a switch 15 in sequence. The non-polar step-down capacitor 13, the full-wave rectifier bridge 14 and the switch 15 can use existing ones. The non-polar step-down capacitor 13 can convert high-voltage AC into low-voltage AC. The function of the full-wave rectifier bridge 14 is to convert AC into DC. The function of the switch 15 is to control the connection and disconnection of the entire circuit. The figure shows two situations of the circuit in the power-on and power-off states. The full-wave rectifier bridge 14 is also connected to a storage circuit. The storage circuit includes a first branch, a second branch, and a third branch. The first branch, the second branch, and the third branch are connected in parallel. The first branch is provided with a resistor 16, the second branch is provided with a charging diode 17, and the third branch is provided with a discharge diode 18. The third branch is also connected in series with an electromagnet body 22. The second and third branches are both connected in series with a fourth branch. The fourth branch includes several fifth branches connected in parallel, each of which has a capacitor body 19 fixed thereto. Specifically, when power is applied, the circuit enters the interior of the three capacitor bodies 19 through the charging diode 17 on the second branch to charge. At the same time, due to the presence of the discharge diode 18, the current cannot pass through the discharge diode 18 and therefore cannot flow into the electromagnet body 22, causing it to be in an inoperative state. When the power is cut off, the charge in the capacitor body 19 is released, and the fourth branch, the third branch, and the first branch form a series loop circuit. When the current flows from the third branch through the second branch, since the charging diode 17 on the second branch is at a high potential, the current cannot flow back from the second branch to the fourth branch, so it can only flow to the first branch with a low potential to form a complete loop, thereby providing electrical energy to the electromagnet body 22.

[0035] In this embodiment, a button device is further provided on the side wall of the electric control box 12. The button device can be purchased on the market. The button device is electrically connected to the switch 15. By pressing the button device, the on / off function of the switch can be changed.

[0036] In this embodiment, the electromagnet assembly 2 further includes an electromagnet housing 21 . The electromagnet housing 21 is a rectangular parallelepiped structure, and the electromagnet body 22 is fixed in the electromagnet housing 21 .

[0037] This embodiment also includes a case connecting plate 3, a Z-shaped structure consisting of a center plate and two side plates. The side plates are fixed to the top and bottom ends of the center plate, and are located on either side of the center plate. The electronic control assembly 1 and the electromagnet assembly 2 are fixed to the top and bottom ends of the center plate with screws, and are both located on the inside of the side plates. The electronic control assembly 1 and the electromagnet assembly 2 are simultaneously secured to the required locations (the fixed ends of the opening and closing mechanism) by the case connecting plate 3.

[0038] In this embodiment, the permanent magnet body is fixed in the permanent magnet anti-shatter cover 41 . The permanent magnet anti-shatter cover 41 is made of steel and can effectively prevent the permanent magnet body from being damaged.

[0039] In this embodiment, the permanent magnet body is a cylindrical structure, and a rubber ring is provided on the outside of the permanent magnet body. The rubber ring is located between the permanent magnet body and the permanent magnet anti-shatter cover 41. The rubber ring can further prevent the permanent magnet body from being worn.

[0040] In this embodiment, the permanent magnet anti-shatter cover 41 is further hinged to the permanent magnet bracket 42 through bolts and nuts, and the permanent magnet bracket 42 can be tightened and fixed by the bolts and nuts. The permanent magnet bracket 42 can fix the permanent magnet body at the position where it needs to be installed by screws.

[0041] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
