Description

Cleaning equipment

Technical Field

Some cleaning devices on the market at present have the functions of wet mopping and floor washing, so that a water tank is inevitably required to be arranged on the cleaning device, the water tank can be lack of water or no water in the using process, and in the case of continuing to clean, the functions of mopping and floor washing cannot be well performed. Therefore, when the water tank is lack of water or is empty, the user needs to be reminded to add water or replenish water to the water tank, and thus, a device for detecting that the water tank is empty or empty needs to be provided. The existing mature schemes are a scheme of a floating ball and a hall sensor, a scheme of placing a capacitive sensor at the bottom of a water tank or a scheme of arranging the capacitive sensor on a channel connected with an outlet of the water tank, but the schemes have respective defects at present, for example, the scheme of placing the capacitive sensor at the bottom of the water tank has the following defects: since the sensor is usually placed on one side of the bottom of the water tank, when the water tank is inclined to the other side to expose the capacitive sensor, the sensor can feed back a signal that the water tank is empty, but actually, the water tank may store a large amount of water, so that false alarm occurs. Some solutions in the prior art need to add a detection cavity in the liquid flow channel, and water flows through the detection cavity, and a detector arranged on the detection cavity is used to detect whether water passes through the detection cavity, so that the manufacturing complexity is increased by the solutions.

Wherein, the fluid can be any one of clear water, cleaning agent and mixed liquid of clear water and cleaning agent. The fluid storage device 1 may be a container capable of containing liquid, and the specific shape is not limited strictly. The fluid outlet line 2 may be a hard tube extending along a path, or a hose that can change the path, and is selected according to the type of the cleaning device and the structural design of the cleaning device.

The fluid sorting device 3 can comprise a plurality of nozzles for the cleaning fluid to the cleaning elements, the fluid reservoir 1 being connected to the nozzles via the fluid outlet line 2 in order to supply the fluid in the fluid reservoir 1 to the nozzles via the fluid outlet line 2 in order to wet the cleaning head 7 via the nozzles.

The control device may be implemented using various Application Specific Integrated Circuits (ASICs), Digital Signal Processors (DSPs), Digital Signal Processing Devices (DSPDs), Programmable Logic Devices (PLDs), Field Programmable Gate Arrays (FPGAs), micro-central control elements, microprocessors, or other electronic elements.

The control device is electrically connected with the fluid detection device in the embodiment, the control device is electrically connected with the fluid detection device, the control device is used for outputting a corresponding control instruction according to a detection result of the fluid detection device, that is, if the fluid detection device detects that fluid exists in the fluid output pipeline 2, that is, fluid still flows into the fluid storage device 1 to the fluid output pipeline 2, the control device outputs a control instruction of normal operation to other devices of the cleaning equipment based on the detection result so as to control the cleaning equipment to normally perform cleaning operation, if the fluid detection device detects that no fluid exists in the fluid output pipeline 2, that is, no fluid exists in the fluid storage device 1 to enter the fluid output pipeline 2, which indicates that no cleaning liquid completely exists in the fluid storage device 1 or the fluid storage device 1 has insufficient fluid amount and cannot enter the fluid output pipeline 2, the control means outputs a control instruction for stopping the operation to other devices of the cleaning apparatus based on the detection result to control the cleaning apparatus to stop the operation, and the operation can be resumed only after the user adds the fluid into the fluid storage device 1. Therefore, whether fluid exists in the fluid output pipeline 2 is detected by utilizing the fluid detection device arranged outside the fluid output pipeline 2, whether fluid capable of meeting cleaning operation exists in the fluid storage device 1 is judged, the cross sectional area of the fluid output pipeline 2 is small, the situation that the fluid detection device cannot detect the fluid due to the inclination of cleaning equipment is avoided, whether fluid capable of meeting the cleaning operation exists in the fluid storage device 1 can be accurately reflected, the accuracy of a detection result is improved, the structure is simple, and the assembly is convenient.

The fluid detection device includes a contact sensor 4 and a non-contact sensor 5, the non-contact sensor 5 may be located outside the fluid output pipeline 2, and an electrode 403 of the contact sensor 4 needs to extend into the fluid output pipeline 2, which will be described in detail later.

Further, the main body 6 may further be provided with an alarm device electrically connected to the control device, and when the control device determines that there is no fluid in the fluid output pipeline 2, the control device controls the alarm device to send an alarm signal to remind a user to add fluid into the fluid storage device 1.

In a particular application, the fluid detection device is a non-contact sensor 5 or a contact sensor 4.

The sensing part of the touch sensor 4 protrudes into the fluid output pipeline 2, and whether the fluid is in the output pipeline 2 is determined by detecting whether the fluid is in contact with the sensing part.

As shown in fig. 1, touch sensor 4 includes an electrode 403 and a second processing circuit 401 electrically connected to electrode 403, where electrode 403 extends into fluid output line 2. Detection is performed by the electrodes 403 being in contact with a fluid, specifically, the electrodes 403 include a positive electrode 4031 and a negative electrode 4032; the second processing circuit 401 is electrically connected to the positive electrode 4031 and the negative electrode 4032, respectively, and the positive electrode 4031 and the negative electrode 4032 extend into the fluid output pipeline 2.

The positive electrode 4031 and the negative electrode 4032 extend into the fluid output pipeline 2 to generate a real-time sensing signal; the second processing circuit 401 senses a signal in real time, and then determines whether the real-time sensing signal is the same as an environmental sensing signal, wherein the environmental sensing signal is a sensing signal generated when the contact sensor is in contact with a fluid; if the real-time sensing signal is the same as the environmental sensing signal, the second processing circuit 401 determines that the fluid storage device 1 stores fluid capable of meeting the cleaning operation, so that the control device controls the cleaning equipment to continue to work; if the real-time sensing signal is different from the environmental sensing signal, the second processing circuit 401 determines that no fluid satisfying the cleaning operation is stored in the fluid storage device 1, so that the control device controls the cleaning apparatus to stop operating.

Further, as shown in fig. 1, the electrode 403 includes a conductor 402 and a metal sheet; the metal sheet is positioned in the fluid output pipeline 2, one end of the electric conductor 402 is electrically connected with the second processing circuit 401, and the other end of the electric conductor 402 extends into the fluid to be connected with the metal sheet.

The metal sheet can increase the contact area with the fluid, thereby improving the detection range of the fluid detection device and ensuring that the detection result is more accurate.

Specifically, as shown in fig. 1, the metal sheet is an ellipse, and the direction of the major axis of the ellipse is the same as the extending direction of the outer wall of the fluid output pipeline 2.

The oval metal sheet is matched with the fluid output pipeline 2 in shape, and the contact area of the metal sheet and the fluid is greatly increased. Furthermore, the metal sheet is a copper sheet, so that the corrosion of the fluid to the metal sheet is reduced, and the service life of the contact type fluid detection sensor 4 is prolonged.

The non-contact sensor 5 will change its position as the fluid moves away from or towards it to detect the presence of fluid in the fluid output channel. The non-contact sensor 5 can be realized without contacting with the fluid, so that the influence of instability of the liquid level on the detection result is effectively reduced, and the reliability of the detection result is improved.

Specifically, as shown in fig. 2 and 4, the proximity sensor 5 is a capacitive sensor.

When the fluid approaches, the parasitic capacitance changes, and the detection of whether the fluid exists in the fluid output pipeline 2 can be realized according to the change of the parasitic capacitance.

Specifically, the capacitive sensor includes a sensing portion 501 surrounding the fluid output pipe 2 and a first processing circuit electrically connected to both ends of the sensing portion 501. Optionally, the sensing portion 501 is a spring.

The first processing circuit 502 makes a difference between the generated real-time sensing capacitance value and the environment sensing capacitance value, wherein the environment sensing capacitance value is a sensing capacitance value generated when no fluid exists in the fluid output pipeline, then the difference is compared with a preset threshold value by the control device, if the difference is greater than or equal to the preset threshold value, the fluid output pipeline 2 is judged to be filled with the fluid, so that the fluid which can meet the cleaning operation is determined to be stored in the fluid storage device 1, and then the control device controls the cleaning equipment to continue to work according to the detection result; if the difference is smaller than the preset threshold value, it is determined that no fluid exists in the fluid output pipeline 2, and therefore it is determined that no fluid capable of meeting the cleaning operation exists in the fluid storage device 1, and then the control device controls the cleaning equipment to stop working according to the detection result.
