When the tank 51 stores liquid, the liquid in the tank 51 flows out through the liquid outlet structure 520, so that the liquid detection sensor 58 is immersed in the liquid environment, and the liquid detection sensor 58 detects the liquid environment and outputs a first signal. When the liquid in the tank 51 is empty, the tank 51 is empty of liquid, and the liquid detection sensor 58 is in an air environment, outputting a second signal. Wherein the first signal is different from the second signal. Since the liquid detection sensor 58 outputs different signals in the case of the liquid environment and the air environment, the liquid storage condition in the tank 51 can be recognized by the different detection signals of the liquid detection sensor 58.

The reminding device is electrically connected with the liquid detection sensor 58, receives the signal output by the liquid detection sensor 58, and sends out a reminding signal in response to the second signal when the reminding device receives the second signal so as to warn a user that the tank body 51 is short of liquid and the cleaning liquid needs to be supplemented. When the detection signal of the liquid detection sensor 58 is the first signal, the tank 51 is considered to have liquid, and the reminder does not respond, that is, does not send out a warning signal. In one embodiment, when the liquid detection sensor 58 detects a first signal, the reminding mechanism further sends a display signal indicating that liquid is stored in the tank 51, so as to indicate that liquid is stored in the tank without replenishing liquid.

The liquid tank assembly provided by the upper embodiment can identify whether liquid exists in the tank body of the liquid tank assembly or not, and sends out a reminding signal under the condition of liquid shortage in the tank body, so that a user is reminded of adding liquid into the tank body in time, normal liquid tank assembly liquid supply is guaranteed, and normal work is guaranteed.

The abutting portion includes a thimble 561, when the box 51 is mounted on the mounting seat 56, the abutting portion cooperates with the liquid outlet structure 520, the thimble 561 abuts against the valve core 525 to move upward, the valve core 525 moves to a position in clearance fit with the outlet sealing ring 522, and thus, the liquid can flow out through the clearance.

In order to facilitate the detachment and installation of the box body 51, the box body 51 is further provided with a lifting handle 517 and a lock 513, and the lifting handle 517 is convenient for being held by a human hand, so that the movement and the liquid supplementing action of the box body 51 are operated. The lock 513 is used to position and fix the case 51 after the case 51 is mounted to the mount 56. The tank 51 further includes a filling port 53 for replenishing the liquid. In this embodiment, the liquid filling opening 53 is disposed on the opposite surface of the liquid outlet structure 520.

In one embodiment, the fluid detection sensor 58 is disposed within the adapter 57. The liquid detection sensor 58 is located at the upstream of the infusion pipeline and close to the liquid outlet structure 520, so that the condition of air filling in the infusion pipeline can be reduced, liquid supplementing is timely reminded, the time for air evacuation is reduced, and the liquid tank assembly is enabled to continuously discharge liquid. In another embodiment, the fluid detection sensor 58 may also be disposed within the fluid tube.

In this embodiment, the reminding device includes a reminding lamp, and when the liquid detection sensor 58 outputs the second signal, the reminding lamp is powered on and turned on, so as to remind the user of the lack of liquid in the tank body. Illustratively, the reminding lamp is constantly on in green when the first signal is received, and the reminding lamp is constantly on in red or flashes in red when the second signal is received. The reminding device may further include a buzzer, or one or more of a display screen for displaying the reminding signal and a voice player for playing the reminding signal, which is not limited herein.

In one embodiment, referring to fig. 4-6, the liquid detection sensor 58 is a light detection sensor, and the principle of light emission and refraction is used to detect whether the liquid detection sensor 58 is in a liquid environment.

Since the liquid detection sensor 58 emits the second signal, the warning device emits a warning signal. Fig. 6 shows a schematic diagram of the propagation of the optical signal of the liquid detection sensor 58 in the case of the liquid environment of the liquid detection sensor 58, the optical signal emitted by the light emitting unit 582 is refracted through the reflecting structure 583 and outwards, the optical signal is not received by the light receiving unit 584, and at this time, the liquid detection sensor 58 outputs the first signal. The reminding device does not send out reminding signals of liquid shortage.

When the liquid detection sensor is in an air environment, the light signal emitted by the light emitting unit 582 is reflected back by the reflecting

structures
