[0026] Please refer to Figure 1 The utility model embodiment provides a kind of voltage stabilizing device 100. Voltage stabilizing device 100 is applied to voltage stabilizer 1000. Voltage stabilizer 1000 is equipped with first electric circuit 201 and second electric circuit 202. Among them, one end of first electric circuit 201 and second electric circuit 202 is used as input end INPUT for inputting commercial power 300, and the other end of first electric circuit 201 and second electric circuit 202 is used as output end OUTPUT and exports commercial power 300 to the electronic equipment 400, such as air conditioner, television, refrigerator and other household appliances connected to voltage stabilizer 1000. First electric circuit 201 and second electric circuit 202 in the application can be live wire and neutral wire respectively.
[0027] As Figure 1 As shown, voltage stabilizing device 100 includes relay group 1, controller 2 and delay switch 3. Among them, relay group 1 is arranged in first electric circuit 201. Relay group 1 includes first relay 11, second relay 12 and third relay 13 connected in sequence. First relay 11, second relay 12 and third relay 13 have independent switch state from each other. Specifically, first electric circuit 201 is equipped with first switch branch D1, second switch branch D2 and third switch branch D3. More specifically, first relay 11 and second relay 12 are single-pole double-throw switches. First relay 11 and second relay 12 are connected by first switch branch D1 and second switch branch D2, and second relay 12 and third relay 13 are connected by third switch branch D3.
[0028] Correspondingly, the switching states of the first relay 11 and the second relay 12 respectively include a first state indicating being connected to the first switching branch D1, and a second state indicating being connected to the second switching branch D2. The switching state of the third relay 13 includes a conducting state indicating being connected to the third switching branch D3, and a disconnecting state indicating being disconnected from the third switching branch D3.
[0029] Further, when the switching states of the first relay 11 and the second relay 12 are the same, the first switching branch D1 or the second switching branch D2 is conducted.
[0030] The controller 2 is electrically connected with the first relay 11, the second relay 12 and the third relay 13 respectively. Specifically, the voltage stabilizing device 100 is provided with a first control branch C1, a second control branch C2 and a third control branch C3. The first control branch C1 is used to realize the electrical connection between the controller 2 and the first relay 11. The second control branch C2 is used to realize the electrical connection between the controller 2 and the second relay 12. The third control branch C3 is used to realize the electrical connection between the controller 2 and the third relay 13.
[0031] The delay switch 3 is electrically connected to the controller 2 to output the delay gears of different relays to the controller 2. The delay gears include delay time and switching state. The controller 2 sets different relays according to the delay gears of different relays respectively. Specifically, the delay switch 3 includes a plurality of sub-delay switches 31 electrically connected to the controller 2. Different sub-delay switches 31 correspond to output different delay gears. More specifically, the delay gears corresponding to different sub-delay switches 31 can be pre-set according to the control needs of the user. In other embodiments, the delay switch 3 is also provided with a selection switch (not shown in the figure) for selecting to set the switching state of a specific relay. The selection switch is respectively electrically connected with the first control branch C1, the second control branch C2 and the third control branch C3, so as to enable the user to select to set the switching state of the relay on the corresponding control branch and the delay time thereof. For example, the user selects to set the delay gears of the first relay 11, the third relay 13 and the second relay 12 in the order of the first relay 11, the third relay 13 and the second relay 12 through the selection switch, and sets different relays through a plurality of sub-delay switches 31 as follows:
[0032] 1. The first relay 11: delay time-7s, switching state-second state;
[0033] 2. The third relay 13: delay time-17s, switching state-conducting state;
[0034] 3. The second relay 12: delay time-12s, switching state-second state.
[0035] Accordingly, the voltage stabilizer 100 will output the commercial power 300 from the input end INPUT to the electronic device 400 through the output end OUTPUT in the state that the second switch branch D2 is turned on after the current time 12s and the third switch branch D3 is turned on after the current time 17s.
[0036] In the embodiment, the first switch branch D1 and the second switch branch D2 are different switch branches. When the third relay 13 is in the on state, the commercial power 300 output by the output end OUTPUT after the first switch branch D1 is turned on is different from the commercial power 300 output by the output end OUTPUT after the second switch branch D2 is turned on.
[0037] In the embodiment, the voltage stabilizer 100 further has a first detection branch E1. The first detection branch E1 is connected between the controller 2 and the input end INPUT and the first relay 11, so as to detect whether the commercial power 300 contains a surge input to the input end INPUT, thereby facilitating detection of whether the electronic device 400 has a risk of being damaged by receiving the surge.
[0038] It can be understood that the time delay of the third relay 13 is longer than the time delay of the first relay 11 and the second relay 12, that is, the connection state of the first switch branch D1 and / or the second switch branch D2 is changed first, and then the connection state of the third switch branch D3 is changed, so as to ensure that the commercial power 300 can be detected by the first detection branch E1 before being output through the output end, whether the commercial power 300 contains a surge.
[0039] Further, the voltage stabilizer 100 further has a second detection branch E2. The second detection branch E2 is connected between the controller 2 and the output end OUTPUT and the third relay 13, so as to detect whether the on-off frequency of the commercial power 300 through the third switch branch D3 exceeds a preset on-off frequency, thereby facilitating detection of whether the electronic device 400 has a risk of being damaged by receiving the commercial power 300 with a high on-off frequency.
[0040] Please refer to Figure 3 The utility model embodiment provides a voltage stabilizer 1000. The voltage stabilizer 1000 comprises a power supply circuit and a voltage stabilizer 100. The power supply circuit comprises a first electric circuit 201 and a second electric circuit 202. Wherein, one end of the first electric circuit 201 and the second electric circuit 202 is used as the input end INPUT for the commercial power 300 input, and the other end of the first electric circuit 201 and the second electric circuit 202 is used as the output end OUTPUT and exports the commercial power 300. The specific features of the voltage stabilizer 100 have been described in the foregoing, and will not be repeated here.
[0041] In the above embodiment, by setting the relay group, the controller and the time delay switch, the voltage stabilizer can control the output according to the time delay position selected by the user when the mains input, effectively avoids the surge transmission to the electronic equipment connected to the output end when the mains input, and reduces the phenomenon that the electronic equipment is frequently powered off due to the frequent on-off of the mains, thereby significantly improving the use stability of the electronic equipment.

Therefore, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technology, the present application also intends to include these modifications and variations.
