[0015] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0016] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0017] The present application describes a garment steamer. The garment steamer reduces the overall cost by simplifying the design of the internal circuit. In addition, the garment steamer can be convenient for users and improve the user experience during use.

[0018] See also Figure 1 , Figure 1Schematic diagram of the circuit of the garment steamer in some embodiments of the present application. The garment steamer 100 may include a power supply 10, a heating element 20, a thermostat 30, a pump 40, a transistor drive circuit 50 and a switch 60. Among them, the power supply 10, the pump 40, the transistor drive circuit 50 and the switch 60 may be connected in series to form a circuit loop, such as a first circuit loop. The power supply 10, the heating element 20, the transistor drive circuit 50 and the switch 60 may be connected in series to form a circuit loop, such as a second circuit loop. The power supply 10, the heating element 20, the thermostat 30 and the switch 60 may be connected in series to form a circuit loop, such as a third circuit loop. The heating element 20 may be connected in parallel with the pump 40. The thermostat 30 may be connected in parallel with the transistor drive circuit 50. The power supply 10 may provide electrical energy for the garment steamer 100. The switch 60 may control the start and stop of the garment steamer 100. The thermostat 30 may sense the temperature of the heating element 20. The temperature controller 30 can control the heating element 20 to work or not work through the transistor driving circuit 50. The transistor driving circuit 50 can control the pump 40 to work through the transistor driving circuit 50 under the control of the temperature controller 30.

[0019] When the switch 60 is turned off, the first circuit loop is not energized, the second circuit loop is not energized, and the third circuit loop is not energized. Thus, the garment steamer 100 does not work.

[0020] When the switch 60 is turned on, the thermostat 30 can be turned on when it senses that the temperature of the heating element 20 is lower than the preset temperature, so that the third circuit loop is energized. The heating element 20 can generate heat when the third circuit loop is energized. The garment steamer 100 can start working.

[0021] Furthermore, the thermostat 30 may control the transistor drive circuit 50 so that the transistor drive circuit 50 is disconnected in the first circuit loop. Thus, the pump 40 does not work. In some embodiments, the transistor drive circuit 50 may be turned on in the second circuit loop so that the heating element 20 may generate heat when the second circuit loop is powered on. In some embodiments, when the thermostat 30 is turned on, the two ends of the transistor drive circuit 50 in the second circuit loop may be short-circuited so that the second circuit loop is not powered on.

[0022] When the switch 60 is turned on, the thermostat 30 may be turned off when it is sensed that the temperature of the heating element 20 is greater than or equal to a preset temperature, so that the third circuit loop is not energized.

[0023] Then, the thermostat 30 can control the transistor drive circuit 50 so that the transistor drive circuit 50 is turned on in the first circuit loop. Then the pump 40 starts to work. In some embodiments, the transistor drive circuit 50 can be turned on in the second circuit loop so that the heating element 20 can generate heat when the second circuit loop is powered on. In some embodiments, the transistor drive circuit 50 can be disconnected in the second circuit loop.

[0024] It can be understood that when the pump 40 starts working, it can provide water to the area where the heating element 20 is located, so that the water is heated by the heating element 20 to generate steam, thereby further realizing the ironing function of the garment steamer 100.

[0025] Furthermore, the temperature of the heating element 20 can be lowered under the action of water, so that the thermostat 30 can sense that the temperature of the heating element 20 is lower than the preset temperature. Then, the thermostat 30 is turned on when sensing that the temperature of the heating element 20 is lower than the preset temperature.

[0026] In addition, in some embodiments, the heat generated by the heating element 20 in the second circuit loop is less than the heat generated by the heating element 20 in the third circuit loop, and is insufficient to compensate for the heat consumed by the heating element 20 in evaporating water.

[0027] The transistor driving circuit 50 in the garment steamer 100 uses transistors that are much cheaper than high-end chips such as processors and microcontroller units, so the cost of the garment steamer 100 controlled by the thermostat 30 and the transistor driving circuit 50 is relatively low.

[0028] In addition, when the garment steamer 100 is in use, the switch 60 can be turned on, and then the heating element 20 and the pump 40 automatically cooperate to intelligently prevent scalding and generate steam. When the garment steamer 100 is not in use, the switch 60 can be directly turned off. During the entire use process of the garment steamer 100, too much human intervention is not required, which is convenient for users and can improve the user experience.

[0031] In some embodiments, the power source 10 may be built into the garment steamer 100. In some embodiments, the power source 10 may be external and may not be part of the garment steamer 100, but it may also be part of the garment steamer 100. Figure 3 , Figure 3 for Figure 1The structure diagram of the garment steamer 100 in some embodiments is shown in the embodiment. The power supply 10 is external, and the garment steamer 100 may include a power connector 101 electrically connected to the thermostat 30, the transistor drive circuit 50, and the switch 60 respectively.

The transistor driving circuit 50 may include a first sub-triode driving circuit 51, a second sub-triode driving circuit 52, a third sub-triode driving circuit 53 and a driving power supply 54.

The driving power supply 54 is electrically connected to the first sub-transistor driving circuit 51 , the second sub-transistor driving circuit 52 , and the third sub-transistor driving circuit 53 respectively to provide power to the first sub-transistor driving circuit 51 , the second sub-transistor driving circuit 52 , and the third sub-transistor driving circuit 53 .

[0037] The first sub-transistor driving circuit 51 may be electrically connected between the first terminal 501 and the second terminal 502 to be electrically connected in the second circuit loop through the first terminal 501 and the second terminal 502 .

[0038] The third sub-transistor driving circuit 53 may be electrically connected between the third terminal 503 and the fourth terminal 504 to be electrically connected in the first circuit loop through the third terminal 503 and the fourth terminal 504 .

[0039] The second sub-transistor driving circuit 52 may be electrically connected between the fifth terminal 505 and the sixth terminal 506 , so as to be electrically connected to the first sub-transistor driving circuit 51 through the fifth terminal 505 , and to the third sub-transistor driving circuit 53 through the sixth terminal 506 .

[0040] When the circuit loop (i.e., the second circuit loop) formed by the first sub-transistor driving circuit 51, the power supply 10, the heating element 20, and the switch 60 in series is turned on, the first end 501 is at a high level. When the circuit loop (i.e., the second circuit loop) formed by the first sub-transistor driving circuit 51, the power supply 10, the heating element 20, and the switch 60 in series is turned off, the first end 501 is at a low level.

[0041] When the first terminal 501 is at a high level, the first sub-transistor driving circuit 51 outputs a low level based on the driving power supply 54 at the fifth terminal 505 .

[0042] When the first terminal 501 is at a low level, the first sub-transistor driving circuit 51 outputs a high level based on the driving power supply 54 at the fifth terminal 505 .

[0043] When the fifth terminal 505 of the second sub-transistor driving circuit 52 is at a high level, the sixth terminal 506 of the second sub-transistor driving circuit 52 outputs a low level based on the driving power supply 54 .

[0044] When the fifth terminal 505 of the second sub-transistor driving circuit 52 is at a low level, the sixth terminal 506 of the second sub-transistor driving circuit 52 outputs a high level based on the driving power supply 54 .

[0045] When the sixth terminal 506 of the third sub-transistor driving circuit 53 is at a high level, the third terminal 503 and the fourth terminal 504 are turned on, so that the circuit loop (i.e., the first circuit loop) formed by the third sub-transistor driving circuit 53 in series with the power supply 10, the pump 40, and the switch 60 is turned on.

[0046] When the sixth terminal 506 of the third sub-transistor driving circuit 53 is at a low level, the third terminal 503 and the fourth terminal 504 are disconnected, so that the circuit loop (i.e., the first circuit loop) formed in series with the third sub-transistor driving circuit 53, the power supply 10, the pump 40, and the switch 60 is disconnected.

[0047] See also Figure 5 , Figure 5 for Figure 4 The schematic diagram of the structure of the transistor driving circuit 50 in some embodiments of the embodiment shown. The first sub-transistor driving circuit 51 can be electrically connected to the sixth terminal 506, so that when the sixth terminal 506 is at a high level, the first sub-transistor driving circuit 51 outputs a low level based on the driving power supply 54 at the fifth terminal 505 to achieve a self-locking function. In some embodiments, when the first circuit loop is turned on, the first sub-transistor driving circuit 51 cooperates with the second sub-transistor driving circuit 52 to maintain the first circuit loop turned on without being affected by the temperature controller 30. For example, the sixth terminal 506 is at a high level, which will make the first circuit loop turned on, and the high level of the sixth terminal 506 is fed back to the first sub-transistor driving circuit 51, which can make the first sub-transistor driving circuit 51 maintain a low level at the fifth terminal 505, and then make the second sub-transistor driving circuit 52 maintain a high level at the sixth terminal 506, so as to achieve a self-locking function and maintain the first circuit loop turned on. Under the control of the thermostat 30 , the third circuit loop does not affect the sixth terminal 506 to maintain a high level, so that the first circuit loop remains conductive without being affected by the thermostat 30 .

[0048] See also Figure 6 , Figure 6 for Figure 5 The schematic diagram of the structure of the transistor driving circuit 50 in some embodiments of the embodiment shown. The transistor driving circuit 50 may also include a fourth sub-transistor driving circuit 55 and an indicator light 56. The first sub-transistor driving circuit 51 is connected in series with the indicator light 56 ​​and the driving power supply 54 to form a circuit loop. The fourth sub-transistor driving circuit 55 is connected in series with the indicator light 56 ​​and the driving power supply 54 to form a circuit loop.

[0049] When the first end 501 is at a high level, the first sub-transistor driving circuit 51 conducts the circuit loop formed by the first sub-transistor driving circuit 51, the indicator light 56, and the driving power supply 54, so that the indicator light 56 ​​sends out a first indication signal. When the first end 501 is at a low level, the first sub-transistor driving circuit 51 disconnects the circuit loop formed by the first sub-transistor driving circuit 51, the indicator light 56, and the driving power supply 54, so that the indicator light 56 ​​does not send out the first indication signal.

When the fifth terminal 505 of the fourth sub-transistor driving circuit 55 is at a low level, the circuit loop formed by the fourth sub-transistor driving circuit 55, the indicator light 56, and the driving power supply 54 is turned off, so that the indicator light 56 ​​does not send out the second indication signal.

[0051] In some embodiments, the indicator light 56 ​​may include a first indicator light 561 and a second indicator light 562. The first indicator light 561 is used to send a first indication signal.

In some embodiments, when the first circuit loop is turned on, the first sub-transistor driving circuit 51 maintains the fourth circuit loop disconnected and is not affected by the thermostat 30. For example, the sixth terminal 506 is at a high level to turn on the first circuit loop, and the high level of the sixth terminal 506 is fed back to the first sub-transistor driving circuit 51, so that the first sub-transistor driving circuit 51 maintains a low level at the fifth terminal 505, and then the second sub-transistor driving circuit 52 maintains a high level at the sixth terminal 506, so as to realize the self-locking function and maintain the first circuit loop turned on. The third circuit loop does not affect the sixth terminal 506 maintaining a high level under the control of the thermostat 30 , so that the first sub-transistor driving circuit 51 disconnects the fourth circuit loop when the sixth terminal 506 maintains a high level without being affected by the thermostat 30 .

[0053] In some embodiments, the indicator light 56, such as the second indicator light 562, is electrically connected to the eighth terminal 508, and then the indicator light 56, such as the second indicator light 562, is connected in series between the fourth sub-transistor driving circuit 55 and the eighth terminal 508, so as to realize the circuit loop formed by the transistor driving circuit 50, such as the fourth sub-transistor driving circuit 55, the indicator light 56, such as the second indicator light 562, and the driving power supply 54, such as the fifth circuit loop. In some embodiments, when the first circuit loop is turned on, the first sub-transistor driving circuit 51 cooperates with the fourth sub-transistor driving circuit 55 to maintain the conduction of the fifth circuit loop without being affected by the thermostat 30. For example, the sixth terminal 506 is at a high level, so that the first circuit loop is turned on, and the high level of the sixth terminal 506 is fed back to the first sub-transistor driving circuit 51, so that the first sub-transistor driving circuit 51 maintains a low level at the fifth terminal 505, and then the second sub-transistor driving circuit 52 maintains a high level at the sixth terminal 506, so as to realize the self-locking function and maintain the conduction of the first circuit loop. The third circuit loop does not affect the sixth terminal 506 maintaining a high level under the control of the thermostat 30 , and the fourth sub-transistor driving circuit 55 turns on the fifth circuit loop when the fifth terminal 505 maintains a low level without being affected by the thermostat 30 .

[0068] See also Figure 2When the switch 60, such as the switch S1, is disconnected, the circuit loop (i.e., the third circuit loop) formed by the power supply 10, the heating element 20, the thermostat 30 and the switch 60, such as the switch S1, is not energized, the circuit loop (i.e., the second circuit loop) formed by the power supply 10, the heating element 20, the transistor drive circuit 50, such as the first sub-transistor drive circuit 51 and the switch 60, such as the switch S1, is not energized, and the circuit loop (i.e., the first circuit loop) formed by the power supply 10, the pump 40, the transistor drive circuit 50, such as the third sub-transistor drive circuit 54 and the switch 60, such as the switch S1, is not energized. Thus, the garment steamer 100 does not work.

[0069] When the switch 60, such as the switch S1, is turned on, the thermostat 30 may be turned on when it senses that the temperature of the heating element 20 is lower than the preset temperature, so that the circuit loop (i.e., the third circuit loop) formed by the power supply 10, the heating element 20, the thermostat 30 and the switch 60, such as the switch S1, is energized. The heating element 20 may generate heat when the circuit loop (i.e., the third circuit loop) formed by the power supply 10, the heating element 20, the thermostat 30 and the switch 60, such as the switch S1, is energized. The garment steamer 100 may start to work.

The gate of the fourth N-channel enhancement type field effect transistor Q4 is in a low level state, the fourth N-channel enhancement type field effect transistor Q4 is not turned on, and the indicator light 56, such as the first indicator light 561 (indicator light LED1), does not emit light.

In some embodiments, when the thermostat 30 is turned on, the first end 501 and the second end 502 can be short-circuited, so that the circuit loop (i.e., the second circuit loop) formed by the power supply 10, the heating element 20, the transistor drive circuit 50 and the switch 60 is not energized.

[0073] When the switch 60 is turned on, the thermostat 30 may be turned off when it is sensed that the temperature of the heating element 20 is greater than or equal to a preset temperature, so that the third circuit loop is not energized.

[0074] Then, the gate of the fourth N-channel enhancement type field effect transistor Q4 is in a high level state, the fourth N-channel enhancement type field effect transistor Q4 is turned on, the fifth terminal 505 is in a low level state, and then the gate of the first P-channel enhancement type field effect transistor Q1 is in a low level state, the first P-channel enhancement type field effect transistor Q1 is turned on, so that the sixth terminal 506 is in a high level state, the gate of the third N-channel enhancement type field effect transistor Q3 is in a high level state, the third N-channel enhancement type field effect transistor Q3 is turned on, so that the transistor drive circuit 50, for example, the third sub-transistor drive circuit 53 is turned on in the circuit loop (i.e., the first circuit loop) formed by the power supply 10, the pump 40, the transistor drive circuit 50 and the switch 60. Then the pump 40 works.

[0075] In some embodiments, the fifth terminal 505 is in a low level state, and thus the gate of the second N-channel enhancement type field effect transistor Q2 may be in a low level state, and the indicator light 56, such as the second indicator light 562 (indicator light LED2), does not emit light.

When the switch 60, such as the switch S1, is turned off, the indicator light 56, such as the first indicator light 561 (indicator light LED1), does not emit light, and the indicator light 56, such as the second indicator light 562 (indicator light LED2) does not emit light.
