That is to say, the original power supply lead is cut into two sections, one end of one section of the lead is provided with an exposed copper sheet as the conductive part 126, one end of the other section of the lead is fixed with the conductive metal part 125, when the computer board 120 is not used, the insulating sheet 129 is placed between the conductive metal part 125 and the conductive part 126 to block current, when the computer board 120 is used, the insulating sheet 129 is pulled away, the conductive metal part 125 is communicated with the conductive part 126, the circuit normally works, the two sections of the lead are at the same potential, and the influence of condensation on the circuit is avoided.

As shown in fig. 4, at least one function of the computer board 120 of the present embodiment can be used to control the on and off of the indicator lights 128 to show the status of the relevant components to the user. Specifically, the computer board 120 further includes a chip 102, a high-speed crystal oscillator (not shown), a low-speed crystal oscillator 103, and an indicator 128 connected to the circuit board 121, where the high-speed crystal oscillator, the low-speed crystal oscillator 103, and the indicator 128 are respectively connected to the chip 102, and the chip 102 is configured to count time through the high-speed crystal oscillator and/or the low-speed crystal oscillator 103 to control lighting and/or extinguishing time of the indicator 128, so as to show different states of relevant components to a user.
Specifically, the chip 102 may be configured to control the indicator lamp 128 to flash for a first preset number of times in a manner of lighting on for a first preset time and lighting off for a second preset time when the circuit board 121 is powered on for the first time through the high-speed crystal oscillator. For example, the first preset time and the second preset time are both 0.5s, the first preset number of times is 5, and when the high-speed crystal oscillator is started, the indicator lamp 128 is controlled to flash for 5 cycles, and the flashing process is on for 0.5s and off for 0.5s, so as to convey a prompt that the relevant components start to work to the user.
The chip 102 is further configured to be clocked by the low speed crystal 103 after the indicator light 128 is flashed for a first preset number of times. That is, after the 5-cycle blinking of the foregoing example is finished, the chip 102 is clocked by the low-speed crystal oscillator 103, and the clocking period is a third preset time, which may be the working life of the relevant components, for example, the third preset time is one year.

The third preset time is longer than the first preset time, longer than the second preset time, longer than the fourth preset time and longer than the fifth preset time. For example, the third preset time is 1s, the fourth preset time is 5s, and the indicator light 128 turns off the flashing state for 5s with the electric quantity of 1s, so as to prompt the user that the service life of the relevant component is expired and the relevant component needs to be replaced in time.

In the embodiment, the high-speed crystal oscillator and the low-speed crystal oscillator are used for timely timing, the high-speed crystal oscillator is used for shorter timing, and the low-speed crystal oscillator 103 is used for longer timing, so that the overall power consumption of the computer board 120 can be reduced, and the service life of the battery 122 can be prolonged.
The relevant component may be an odor elimination component 130 described below, and the odor elimination component 130 may perform odor elimination and purification on the refrigeration and freezing device 100 through physical adsorption.

Specifically, the smell removing component 130 is disposed in the storage chamber 111 and is used for adsorbing the odor in the storage chamber 111 to achieve the effects of removing smell and purifying. For example, the odor removing part 130 includes an adsorption module capable of adsorbing odor in the storage compartment 111, and the adsorption module has a certain life, and when the adsorption module is saturated, the adsorption module needs to be taken out from the storage compartment 111 for desorption or replaced by a new adsorption module.
In order to show the status of the odor removal component 130 to the user, as mentioned above, the computer board 120 of this embodiment further includes the chip 102, the high-speed crystal oscillator, the low-speed crystal oscillator 103 and the indicator lamp 128 connected to the circuit board 121, the high-speed crystal oscillator, the low-speed crystal oscillator 103 and the indicator lamp 128 are all connected to the chip 102, and the chip 102 is configured to count time through the high-speed crystal oscillator and/or the low-speed crystal oscillator 103 to control the on and/or off time of the indicator lamp 128, so as to prompt the status of the odor removal component 130 to the user.
The odor removing component 130 is detachably connected with the computer board 120 and is arranged at the same position of the storage compartment 111.
