Referring to fig. 1-2, an embodiment of the present application provides a clean water tank assembly 50. The clean water tank assembly 50 includes a tank body 51, a switching structure 52, a liquid delivery pipeline 53, a liquid detection sensor 54, a reminder device (not shown), and a liquid pump (not shown).
Wherein, the box 51 is used for holding liquid, and the box 51 has a liquid outlet 511. The adapter 52 is disposed at the liquid outlet 511, and the liquid flows out of the box 51 through the adapter 52. Specifically, the adapter 52 has a closed state and an open state, and when the liquid is contained in the tank 51, the liquid in the tank 51 cannot flow out from the liquid outlet 511 if the adapter is in the closed state, and when the adapter 52 is in the open state, the liquid in the tank 51 flows out through the adapter 52 by the action of the liquid pump.
And the infusion pipeline 53 is used for conveying liquid. The fluid line 53 communicates with the adapter 52 and is located downstream of the adapter 52 in the fluid flow path. Liquid detection sensor 54 sets up in the periphery of infusion pipeline 53, and when box 51 storage liquid, the liquid in the box 51 flows out through switching structure 52 to be in the liquid environment in the infusion pipeline 53, be that there is liquid in the infusion pipeline 53, liquid detection sensor 54 output first signal. When the inside of the infusion line 53 is in an air environment, that is, there is no liquid in the infusion line 53, the liquid detection sensor 54 outputs a second signal. Wherein the first signal is different from the second signal. Since the liquid detection sensor 54 outputs a different signal after the liquid line 53 is detected by the liquid detection sensor 54 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 54.
Referring to fig. 1, an inner tube 55 is disposed in the box 51 and is communicated with the infusion pipeline 53, one end of the inner tube 55 extends to the bottom of the box 51, and the other end of the inner tube 55 is connected to the adapter 52. In the present embodiment, since the adapter 52 is disposed at an upper position, in order to transfer the liquid into the infusion line 53, an inner tube 55 having a distal end extending to the bottom of the tank 51 is provided, so that the liquid can be transferred to the infusion line 53 even when the water level reaches the bottom of the tank 51. In other embodiments, the adapting structure 52 can be directly disposed at the bottom of the box 51 according to different structural layouts of products, and the arrangement can be achieved without disposing the inner tube 55, and only by disposing a through hole communicated with the adapting structure 52.
The reminding device is electrically connected with the liquid detection sensor 54, receives the signal output by the liquid detection sensor 54, 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 54 is the first signal, it is considered that the tank 51 still contains liquid, and the reminder does not respond, i.e., does not send out a warning signal. In one embodiment, when the liquid detecting sensor 54 detects the 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 clear water tank assembly provided by the upper embodiment can identify whether liquid exists in the tank body of the clear water 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, the normal clear water tank assembly liquid supply is guaranteed, and normal work is guaranteed.
Referring to fig. 3, the clean water tank assembly 50 includes a mounting base 512 for mounting the tank body 51. In this embodiment, the case 51 is detachably attached to the mount 512. The mounting base 512 has a mating portion that mates with the adapting structure 52 when the box 51 is mounted to the mounting base 512, and the mating portion mates with the adapting structure 52, and in one embodiment, the adapting structure 52 may have an open and closed design, and is in an open state when mated with the adapting structure 52; when the box 51 is detached from the mounting seat 512, the adaptor structure 52 is in a closed state. The infusion line 53 is located within the mounting 512 and extends downwardly in a coiled arrangement.
Referring to fig. 3, in order to facilitate the detachment and installation of the box body 51, the box body 51 is further provided with a handle 513 and a lock 514, and the handle 513 is convenient for being held by a human hand, so as to operate the movement and the fluid infusion action of the box body 51. The lock 514 is used to position and fix the case 51 after the case 51 is mounted to the mount 512.
In this embodiment, the reminding device includes a reminding lamp, and when the liquid detection sensor 54 outputs the second signal, the reminding lamp is powered on to light, 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 to 7, the liquid detection sensor 54 uses a light detection sensor, and uses the principle of light emission and refraction to detect whether the liquid detection sensor 54 is in a liquid environment.
Referring to fig. 4 and 5, in an embodiment, the liquid detection sensor 54 includes a light emitting unit 541 and a light receiving unit 542, and the light emitting unit 541 and the light receiving unit 542 are respectively disposed on two opposite sides of the liquid transport pipeline 53. Referring to fig. 4, when the infusion pipeline 53 is in an air environment, the light signal emitted from the light emitting unit 541 is directly transmitted to the light receiving unit 542, the light receiving unit 542 receives the light signal, and the liquid detection sensor 54 outputs the second signal. Referring to fig. 5, when the liquid environment is in the liquid environment in the liquid transportation pipeline 53, the light signal emitted by the light emitting unit 541 is refracted to one side of the light receiving unit 542, the light receiving unit 542 does not receive the light signal, and the liquid detection sensor 54 outputs the first signal. In this embodiment, the light emitting unit 541 and the light receiving unit 542 are respectively disposed on two opposite sides of the liquid conveying pipeline 53, and based on the principle that light is refracted in the liquid, the liquid detecting sensor 54 outputs different signals to monitor whether there is a liquid shortage by the aid of the transmission path of the light signal and whether the light receiving unit 542 receives the light signal.
In the embodiment of fig. 4 and 5, the light emitting unit 541 is an infrared emitting unit for emitting an infrared light signal. The light receiving unit 542 is an infrared receiving unit for receiving an infrared light signal. That is, both the light emitting unit 541 and the light receiving unit 542 emit/receive light signals as infrared light signals.
Referring to fig. 6 to 8, in another embodiment, the liquid detection sensor 54 includes a light emitting unit 541 and a light receiving unit 542, the clean water tank assembly 50 further includes a reflective structure located at the periphery of the liquid conveying pipeline 53, the light emitting unit 541 and the light receiving unit 542 are disposed at one side of the liquid conveying pipeline 53, and the reflective structure is disposed at the opposite side of the liquid conveying pipeline 53. Referring to fig. 6, when the infusion pipeline 53 is in an air environment, the reflection structure reflects the light signal emitted by the light emitting unit 541 back, the light receiving unit 542 receives the light signal, and the liquid detection sensor 54 outputs the second signal. Referring to fig. 7 and 8, when the liquid environment is in the liquid environment in the liquid transport pipeline 53, the light signal emitted by the light emitting unit 541 is refracted out to one side of the liquid transport pipeline 53 or the reflection structure, the light receiving unit 542 does not receive the light signal, and the liquid detection sensor 53 outputs the first signal. In this embodiment, the light emitting unit 541 and the light receiving unit 542 are located on the same side of the periphery of the infusion pipeline 53, the periphery of the other side of the infusion pipeline 53 opposite to the light emitting unit 541 and the light receiving unit 542 is provided with a reflection structure to reflect the light signal, and by means of the fact that the transmission path of the light signal is different under different conditions of the presence or absence of liquid in the infusion pipeline 53 and whether the light receiving unit 542 receives the light signal, the liquid detection sensor 54 outputs different signals to monitor whether the liquid is short or not.
Fig. 6 shows a schematic diagram of the light propagation path of the liquid detection sensor 54 in an air environment. In the embodiment shown in fig. 6, the light signal emitted from the light emitting unit 541 is reflected by the reflecting structures 543 and 544 and transmitted to the light receiving unit 542, the light receiving unit 542 receives the light signal emitted from the light emitting unit 541, the signal output by the liquid detecting sensor 54 is the second signal, and it is recognized that the liquid detecting sensor 54 is in the air environment and the tank 51 is empty of liquid. Since the liquid detection sensor 54 sends the second signal, the warning device sends a warning signal. Fig. 7 and 8 are schematic diagrams illustrating propagation of an optical signal of the liquid detection sensor 54 in a liquid environment of the liquid detection sensor 54, and an optical signal emitted by the light emitting unit 541 in fig. 7 is refracted under the action of water through the infusion pipeline 53. The light signal emitted from the light emitting unit 541 in fig. 8 is refracted at the reflecting structure 583 and is refracted outwards. In both cases shown in fig. 7 and 8, the light receiving unit 542 fails to receive the light signal, and the liquid detection sensor 54 outputs the first signal. The reminding device does not send out reminding signals of liquid shortage. The two situations shown in fig. 7 and 8 occur depending on the amount of water in the infusion pipeline 53 and the diameter of the infusion pipeline 53, and only one of the situations may occur, or both situations may exist.
