[0024] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner. The diagrams only show the components related to the present application and are not drawn according to the number, shape, and size of the components in actual implementation.

[0025] The following further illustrates the specific implementation manners of the present application with reference to the drawings.

[0026] Embodiment:

[0027] The embodiment of the present application is publicly described as a preferred case, and other alternative solutions will also be involved in the description, all for the purpose of enabling those skilled in the art to understand and implement.

[0028] This solution discloses a generator assembly for a sprayer. Refer to Figure 1As shown in the figure, it includes a stator 1 and a rotor 2. The stator 1 includes a coil skeleton 11 and a coil winding 12. The rotor 2 includes a cover 21 and a permanent magnet 22. The cover 21 can be made of transparent plastic material. The coil skeleton 11 can also be made of plastic material. The permanent magnet 22 is fixed on the inner circumference of the cover 21. The cover 21 is rotatably mounted on the coil skeleton 11 through a bearing 3. A gear ring 4 is fixedly connected to the outer circumference of the cover 21. The function of the gear ring 4 is to cooperate with external mechanical components. It can drive the rotor 2 to rotate, thereby generating an induced electromotive force in the coil. This is the power generation principle of a common generator, which will not be elaborated here specifically.

[0029] In this solution, the core technology is that a temperature warning module 5 and a humidity warning module 6 are provided on the coil skeleton 11. The temperature warning module 5 issues a temperature alarm when the temperature exceeds the first warning temperature, and the humidity warning module 6 issues a humidity alarm when the humidity inside the cover 21 exceeds the first warning humidity. The coil skeleton 11 remains stationary. Although there is no indication of the "rotating shaft" in the figure, we know that based on the fact that the rotating shaft and the coil skeleton 11 remain stationary and the rotor 2 rotates, it relies on gear meshing transmission to convert mechanical energy into electrical energy. And a circuit board (circuit module) can be fixed on the coil skeleton 11. Specifically, it is the following functional circuit. Figure 1 In the figure, although there is no indication of the "rotating shaft", we know that based on the fact that the rotating shaft and the coil skeleton 11 remain stationary and the rotor 2 rotates, it relies on gear meshing transmission to convert mechanical energy into electrical energy. And a circuit board (circuit module) can be fixed on the coil skeleton 11. Specifically, it is the following functional circuit.

[0030] The coil winding 12 is also connected to a power supply module 7. The power supply module 7 stores the electrical energy generated by the coil winding 12 and also converts the electrical energy into a supply voltage to provide it to the temperature warning module 5 and the humidity warning module 6. The power supply module 7 here has various implementation manners in the prior art and is not unique. Those skilled in the art can all achieve power conversion here. Specifically, it is adjusted through a rectifier circuit to store energy in the battery, and then the battery conducts power transmission through a voltage conversion circuit.

[0031] Reference Figure 2 As shown in the figure, the temperature warning module 5 includes a temperature sensor 51, a temperature warning lamp, a temperature upper limit comparator, and a temperature lower limit comparator.

[0032] The temperature upper limit comparator includes a temperature upper limit regulator 52 and a first comparator 53. The temperature lower limit comparator includes a temperature lower limit regulator 54 and a second comparator 55. The temperature upper limit regulator 52 includes a voltage source Vcc, a resistor R2, and a potentiometer Rp1. The voltage source forms a loop through the resistor R2 and the potentiometer Rp1 in series and then is grounded. Through the adjustment terminal of the potentiometer Rp1, a potentiometer adjustable output is realized. The adjustable output potential Vref1 signal is used as the judgment reference of the comparator. If the signal at the non-inverting terminal of the first comparator 53 is greater than the potential Vref1 signal, a high level is output; otherwise, a low level is output. When a high level is output, the temperature warning lamp (LED1) lights up.

[0033] The temperature sensor 51 is connected to the non-inverting input terminal of the first comparator 53, the upper temperature regulator 52 is connected to the inverting input terminal of the first comparator 53, the output terminal of the first comparator 53 is connected to the temperature warning lamp, the temperature sensor 51 is connected to the inverting input terminal of the second comparator 55, the lower temperature regulator 54 is connected to the non-inverting input terminal of the second comparator 55, and the second comparator 55 outputs a low temperature signal.

[0034] Similarly described, the lower temperature regulator 54 includes a voltage source Vcc, a resistor R5, and a potentiometer Rp2. The set lower temperature signal value is Vref2.

[0035] In specific operation, the generator operates, the coil winding 12 generates electricity, the power supply module 7 transmits power to the temperature sensor 51, and the temperature sensor 51 detects the temperature around the coil bobbin 11. In one example, the upper limit temperature is set to 80 degrees Celsius and the lower limit temperature is set to 10 degrees Celsius. If the current temperature is greater than 80 degrees Celsius, the temperature warning lamp (LED1) will light up. If it is less than 10 degrees Celsius, the second comparator 55 outputs a low temperature signal.

[0036] A first switch 8 is provided on the power supply line between the power supply module 7 and the temperature sensor 51. The first switch 8 (K1) is used as a push-button switch or a toggle switch to realize the on-off control of the function.

[0037] In Figure 2 the humidity warning module 6 includes a humidity sensor 61, a third comparator 62, a humidity reference regulator 63, and a humidity lamp 64. The humidity sensor 61 is connected to the inverting input terminal of the third comparator 62, the humidity reference regulator 63 is connected to the non-inverting input terminal of the third comparator 62, and the output terminal of the third comparator 62 is connected to the humidity lamp 64. The humidity reference regulator 63 includes a voltage source Vcc, a resistor R7, and a potentiometer Rp3. The adjusted set humidity threshold signal is Vref3. In a specific example, this humidity threshold signal Vref3 can represent that the set humidity reference value is 75%. If it exceeds, the humidity lamp 64 will light up.

[0038] For greater intelligence and energy conservation, an execution switch module 9 is provided on the power supply line between the power supply module 7 and the humidity sensor 61. The execution switch module 9 receives the low temperature signal and controls the power supply of the humidity sensor 61.

[0039] Reference Figure 3As shown in the figure, the execution switch module 9 includes a transistor circuit 91 and a relay circuit 92. After receiving the low-temperature signal, the transistor circuit 91 conducts the power supply of the relay circuit 92. After the relay circuit 92 is powered on, it controls the power supply module 7 to supply power to the humidity sensor 61. The transistor circuit 91 consists of a resistor R11, an electronic R12, and a triode Q1. When the signal S1 is at a high level, the triode Q1 is forward-biased and conducts, so that the relay coil K2 in the relay circuit 92 is powered on, causing its normally open switch to close.

[0040] Due to the automatic control by the execution switch module 9, the new working process of this solution is as follows:

[0041] As mentioned above, in a specific example, the warning will not be triggered when the temperature is within a reasonable range. If the temperature is too low, at this time, the low-temperature signal S1 is at a high level, thus controlling the relay to be powered on, enabling the humidity sensor 61 to start working and collect the ambient humidity. If the humidity is too high, exceeding the humidity reference value of 75%, the humidity lamp 64 will be triggered to give a warning. Such intelligent control eliminates the need to manually control the activation of the humidity sensor 61. In the case of a relatively high temperature, it is easy to dissipate water vapor, so the humidity detection can be disabled. If the temperature is relatively low, water accumulation is more likely to occur. Therefore, the temperature condition can be used as a prerequisite to further intelligently control the activation of humidity detection, so that the user can be aware of the humidity and temperature conditions.

[0042] The above embodiments merely illustrate the principles and effects of the present application by way of example, and are not intended to limit the present application. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
