The inventor finds that certain defects exist in the conventional mode of detecting the water fullness of the cleaning machine when the embodiment of the invention is practiced.
For example, one way of detecting water fullness is by using a float, which blocks the suction opening of the recovery tank when the liquid level rises to a certain level, so that the whole machine is stopped. However, the space requirement is high by adopting the float mode, so that the structure in the recycling bin is relatively complex, and the whole volume of the recycling bin is increased.
The other mode is to adopt the metal sheet to detect the liquid level, control the complete machine to stop working by the two metal sheets with the help of the sewage conduction circuit of retrieving, adopt the metal sheet to need connect the metal sheet in the bucket and the metal sheet that the bucket surface is used for connecting the organism with the wire, because the recovery bucket operating mode and solution composition are complicated, the metal sheet has the possibility of being corroded, has changed the resistance of metal sheet after the long-time soaking in the solution bucket is corroded to influence the reliability and the stability that the metal sheet detected the water fullness. And the lead has durability problem, and a sealing structure is needed to be added to protect the circuit from being stable.
In view of the above problems, embodiments of the present invention provide a cleaning apparatus, a liquid level detection device, a detection electrode, and a solution tank that solve the above problems.

Wherein the detection electrode 100 is made of a non-metallic conductive material. The solution tank 300 is mounted on the mounting portion and coupled to the body 50 through two conductive contacts 31.

Referring to fig. 1, fig. 1 shows a hand-held cleaning machine, which includes a machine body 50, wherein a handle for a user to hold is provided at one end of the machine body 50, and a floor brush assembly 51 is provided at the other end.

Referring to fig. 2, as the water in the solution tank 300 continuously increases, the liquid level gradually increases, and contacts the two sensing electrodes 100 when the liquid level increases to a certain height. When the two detection electrodes 100 are immersed in water at the same time, the detection electrodes 100 and the machine body 50 form a communication loop through the conductive contacts 31, a water full signal is transmitted to a main control system in the machine body 50, and the main control system recognizes that the solution barrel 300 is in a water full state, so that the whole machine of the cleaning machine is controlled to stop.
According to the technical scheme provided by the embodiment of the invention, when the detection electrodes 100 are used for detecting the liquid level, the two detection electrodes 100 have small space limitation, the internal structure of the solution barrel 300 is simplified, so that the traditional float liquid level detection mode can be replaced, the advantages of small occupied space are achieved, meanwhile, the detection electrodes 100 are made of non-metal conductive materials, and the wires are not required to be electrically connected, so that the traditional metal sheet liquid level detection mode can be replaced, the processes of wire connection, welding and the like are reduced, the non-metal conductive materials have good corrosion resistance, the durable problem of the wires in complex solutions can be avoided, and the sealing structure is not required to be increased.
Referring to fig. 4, in one embodiment of the present invention, one implementation of the detection electrode 100 is that the detection electrode 100 includes: the electrode body 10, the electrode body 10 is made of a nonmetallic conductive material. For example, the electrode body 10 includes, but is not limited to, being made of a conductive plastic material. The conductive plastic material has conductive performance, so that signal conduction can be realized, corrosion resistance is good, durability is improved, a sealing structure is omitted, and cost is reduced. Meanwhile, the novel plastic injection molding machine is simple in manufacture, can be manufactured through injection molding and other processes, and can be injection molded into different shapes and structures according to different setting requirements, so that the novel plastic injection molding machine is suitable for various working conditions.
With continued reference to fig. 3, in an embodiment of the present invention, one implementation of the electrode body 10 is that the electrode body 10 includes a connection section 11 and a detection section 12. The end of the connecting section 11 far away from the detecting section 12 can be connected with the conductive contact 31 so as to realize communication connection with a main control system on the machine body 50, and the end of the detecting section 12 far away from the connecting section 11 is used for contacting with water so that the detecting electrode 100 and the machine body 50 of the cleaning machine form a communication loop.
Further, in order to increase the conductivity and sensitivity of the detection electrode 100, the surface of the detection section 12 is provided with the metal member 20, and by combining the metal member 20 with the non-metal conductive material, the conductivity of the detection electrode 100 can be improved, so that the detection sensitivity and the detection accuracy can be ensured. The metal member 20 includes, but is not limited to, a metal sheet, a metal rod, and the like.
To further improve the sensitivity of detection, a metal member 20 is provided on the end surface of the detection section 12 remote from the connection section 11. The metal member 20 may be wrapped around the end face of one end of the detection section 12 so that the metal member 20 may contact water at a first time to ensure sensitivity of detection.
Further, the surface of the metal member 20 is provided with a first film layer, and the corrosion resistance of the metal member 20 can be increased by the first film layer, so that the corrosion resistance, conductivity and hydrophilicity of the detection electrode 100 can be increased. One implementation of the first film layer is to coat the surface of the metal member 20 by a surface treatment process or to coat the surface of the metal member 20 by an electroplating process. The first film layer includes, but is not limited to, a metal material, and in one implementation, the first film layer is a dacromet film layer, and the dacromet film layer includes an alloy material such as aluminum, zinc, and the like. The first film layer contains abundant oxygen ions, and the solution in the solution barrel 300 contains hydroxyl ions, so that the hydroxyl ions can rapidly capture the oxygen ions, and the contact resistance of the surface of the detection electrode 100 can be reduced. Therefore, the first film layer can not only increase the corrosion resistance and conductivity of the detection electrode 100, but also increase the hydrophilic performance of the detection electrode 100.
The metallic member 20 may be disposed on the detection section 12 in a variety of ways, one possible way being that the metallic member 20 is embedded on the surface of the detection section 12 by an injection molding process. The electrode body 10 can be made by injection molding of conductive plastic material, and when injection molding operation is performed, the metal member 20 can be simultaneously injection molded on the detection section 12, so that the metal member 20 is embedded on the detection section 12, the metal member 20 does not occupy additional space, and the occupied space of the detection electrode 100 is not increased additionally.
To accommodate a variety of different connection conditions, the connection section 11 may be correspondingly configured in different shapes and configurations, and one manner of realisation is that with continued reference to fig. 1, the connection section 11 includes a plurality of bent sections. The connection of the connecting section 11 is realized through a plurality of bending sections, so that the displacement of the connecting section 11 can be reduced, and the stability of the connecting section 11 is improved. Further, the bending sections can be set according to different requirements, for example, a portion of the bending sections are bent along the width direction of the detecting section 12, and a portion of the bending sections are bent along the length direction of the detecting section 12. Of course, the detecting section 12 may be configured as a straight rod or other shapes according to different detecting requirements, and in the embodiment of the present invention, the shapes of the detecting section 12 and the connecting section 11 are not specifically limited.
The detection electrode 100 may be applicable to various schemes for detecting a liquid level, for example, the detection electrode 100 may be applied to the solution tank 300, two conductive contacts 31 are respectively provided on the wall of the tank body 40, one end of the detection electrode 100 is connected to the conductive contacts 31, and the other end is used for detecting a liquid level.
For another example, referring to fig. 3 and 5, the tub body 40 has a mounting opening, and the solution tub 300 further includes an upper cover 30, and the upper cover 30 is coupled to the tub body 40 and covers the mounting opening. Two conductive contacts 31 are disposed on the upper cover 30, and two detection electrodes 100 are respectively connected to the upper cover 30 and electrically connected to the two conductive contacts 31. Referring to fig. 2, the upper cover 30 is connected to the tub body 40 of the solution tub 300, and the two sensing electrodes 100 extend into the tub body 40 at least partially, and in use, water in the solution tub 300 is continuously increased so that the liquid level is gradually increased, and when the liquid level is increased to a certain height, the two sensing electrodes 100 are contacted. When the two detection electrodes 100 are immersed in water at the same time, the detection electrodes 100 and the machine body 50 of the cleaning machine form a communication loop through the conductive contacts 31 on the upper cover 30, a water full signal is transmitted to a main control system in the machine body 50, and the main control system recognizes that the solution barrel 300 is in a water full state, so that the whole machine of the cleaning machine is controlled to stop. It should be noted that, the water-full state described herein does not necessarily mean that the space in the solution tank 300 is filled with water, but may also mean that the liquid level in the solution tank 300 is raised to a certain height, for example, the liquid level is raised to a position where the liquid level contacts both the detection electrodes 100, that is, the water-full state.
Based on the detection electrode 100 in the foregoing embodiment, correspondingly, referring to fig. 2 and 5 in conjunction with fig. 3, an embodiment of the present invention further provides a liquid level detection device 200, including: the upper cover 30 and the two detection electrodes 100, the detection electrodes 100 may be realized by the detection electrodes 100 described in the above embodiments.

During use, the water in the solution tank 300 is continuously increased so that the liquid level is gradually increased, and when the liquid level is increased to a certain height, the two detection electrodes 100 are contacted. When the two detection electrodes 100 are immersed in water at the same time, the detection electrodes 100 and the machine body 50 of the cleaning machine form a communication loop through the conductive contacts 31 on the upper cover 30, a water full signal is transmitted to a main control system in the machine body 50, and the main control system recognizes that the solution barrel 300 is in a water full state, so that the whole machine of the cleaning machine is controlled to stop. It should be noted that, the water-full state described herein does not necessarily mean that the space in the solution tank 300 is filled with water, but may also mean that the liquid level in the solution tank 300 is raised to a certain height, for example, the liquid level is raised to a position where the liquid level contacts both the detection electrodes 100, that is, the water-full state.
According to the technical scheme provided by the embodiment of the invention, the liquid level detection device 200 can be suitable for various liquid level detection schemes, when the liquid level is detected, the two detection electrodes 100 have small space limitation, the internal structure of the solution barrel 300 is simplified, so that the liquid level detection device can replace the traditional float liquid level detection mode, and has the advantage of small occupied space.
Further, referring to fig. 4, one implementation of the detection electrode 100 is that the detection electrode 100 has a connection section 11 and a detection section 12.

One way of connecting the connecting section 11 to the upper cover 30 is that the upper cover 30 has a connecting channel, one end of which is provided with a conductive contact 31. The connection section 11 extends into the connection channel to connect with the conductive contact 31. The connecting channel can be a cavity structure arranged in the upper cover 30, can also be a groove structure arranged on the surface of the upper cover 30, and can ensure that when the connecting section 11 is connected with the upper cover 30 through the connecting channel, no extra space is occupied, the inner part of the upper cover 30 is utilized, the connecting section 11 is protected through the upper cover 30, the interference of the connecting section 11 from the outside is reduced, and the signal transmission is more sensitive. When the connection channel is provided inside the upper cover 30, the connection section 11 is not visible from the outside, so that the liquid level detection apparatus 200 is more beautiful as a whole.
Further, in order to increase the conductivity and sensitivity of the detection electrode 100, the surface of the detection section 12 is provided with the metal member 20, and by combining the metal member 20 with the non-metal conductive material, the conductivity of the detection electrode 100 can be improved, so that the detection sensitivity and the detection accuracy can be ensured. The metal member 20 includes, but is not limited to, a metal sheet, a metal rod, and the like. To further improve the sensitivity of detection, a metal member 20 is provided on the end surface of the detection section 12 remote from the connection section 11.

The first film layer contains abundant oxygen ions, and the solution in the solution barrel 300 contains hydroxyl ions, so that the hydroxyl ions can rapidly capture the oxygen ions, and the contact resistance of the surface of the detection electrode 100 can be reduced. Therefore, the first film layer can not only increase the corrosion resistance and conductivity of the detection electrode 100, but also increase the hydrophilic performance of the detection electrode 100.
Further, when the detection electrode 100 is made of a non-metal conductive material, a first film layer is disposed on the surface of the detection electrode 100 made of the non-metal conductive material, so as to increase the hydrophilic performance of the detection electrode 100 in the solution barrel 300.

Of course, the surface of the detection electrode 100 may be coated with the first film layer accordingly.
In order to avoid interference to the detection electrodes 100 when water flows into the solution tank 300, one implementation manner is that, referring to fig. 5, a lower cover 32 is provided on the upper cover 30, a water blocking groove (not shown in fig. 5) is provided at one end of the lower cover 32 away from the upper cover 30, and two detection electrodes 100 are respectively disposed on the outer walls of the water blocking groove. The water inlet of the solution barrel 300 can discharge water into the water blocking groove, and the water flow is separated by blocking the inner groove wall of the water blocking groove, so that the direct contact between the water flow and the detection electrode 100 is avoided, otherwise, the water flow may flow down along the detection electrode 100, thereby disturbing the detection electrode 100 and causing the detection electrode 100 to report water fullness by mistake. For example, referring to fig. 2, a water inlet pipe 42 is disposed in the solution tank 300, an inlet of the water inlet pipe 42 penetrates through the bottom of the tank body 40, an outlet of the water inlet pipe 42 extends into the water blocking groove, water flows from the inlet into the water inlet pipe 42, flows out from the outlet, and flows into the water blocking groove, and is blocked by an inner groove wall of the water blocking groove to be separated, so as to avoid direct contact between the water and the detection electrode 100.
Another way to avoid the interference of the water flow to the detection electrodes 100 is to provide a baffle on the upper cover 30 (the lower cover 32 in fig. 5 can be regarded as a baffle), and both detection electrodes 100 are disposed on one side of the baffle. The water inlet of the solution tank 300 may be disposed at a side of the baffle opposite to the detection electrode 100, and the water flow is blocked by the baffle, so as to avoid direct contact between the water flow and the detection electrode 100. For example, referring to fig. 2, the lower cover 32 in fig. 2 may be regarded as a baffle, the solution tank 300 is provided with the water inlet pipe 42, the outlet of the water inlet pipe 42 is located at the opposite side of the baffle from the detection electrode 100, that is, the baffle is located between the outlet of the water inlet pipe 42 and the detection electrode 100, the outlet of the water inlet pipe 42 is separated from the detection electrode 100, water flows into the water inlet pipe 42 from the inlet and flows out from the outlet, and the flow direction of the water is indicated by the dashed arrow in fig. 2, and the water flow is blocked by the baffle to avoid the direct contact between the water flow and the detection electrode 100.
In order to make the relative position of the detection electrode 100 more stable, with continued reference to fig. 5, a support 33 is disposed on the outer wall of the water blocking groove, or a support 33 is disposed on the baffle, and the detection electrode 100 is disposed on the support 33. The support frame 33 provides support for the detection electrode 100, so that the relative displacement of the detection electrode 100 can be reduced, the relative position of the detection electrode 100 is more stable, and the sensitivity and accuracy of detection are ensured. Further, the supporting frame 33 and the water retaining groove or the baffle plate can be in an integrated structure, so that the connection strength between the supporting frame 33 and the water retaining groove or the baffle plate is improved, and the stability is better.
Further, the support 33 is provided with a mounting groove with a lateral opening, and the detection electrode 100 is disposed in the mounting groove.

In the embodiment of the present invention, one way of generating a loop between the detection electrode 100 and the main control system in the machine body 50 is that after the two detection electrodes 100 contact water at the same time, the water is conducted by a circuit, so that the detection electrode 100 and the machine body 50 of the cleaning machine form a communication loop through the conductive contact 31 on the upper cover 30, a water full signal is transmitted to the main control system in the machine body 50, and the main control system recognizes that the solution tank 300 is in a water full state, thereby controlling the complete machine of the cleaning machine to stop.
Another way to create a circuit between the sensing electrodes 100 and the host system within the body 50 is to use the potential difference between the two sensing electrodes 100 to create a circuit. One implementation is that one conductive contact 31 of the two conductive contacts 31 is grounded. Grounding may be achieved by way of an external lead, or by other means. For example, when the conductive contact 31A is grounded, the detection electrode 100 connected to the conductive contact 31A is grounded, the main control system detects that the voltage of the conductive contact 31A is zero, and when the conductive contact 31B is not grounded, the detection electrode 100 connected to the conductive contact 31B is not grounded, the main control system detects that the voltage of the conductive contact 31B is greater than zero, a voltage difference is formed between the conductive contact 31A and the conductive contact 31B, and the main control system detects the voltage difference and compares the voltage difference with a standard value to determine whether the water is full.
Alternatively, referring to fig. 3, the upper cover 30 is further provided with a grounding contact 34, and one of the conductive contacts 31 is connected to the grounding contact 34 to achieve grounding. For example, the conductive contact 31A is connected to the ground contact 34, so that the conductive contact 31A is grounded, the detection electrode 100 connected to the conductive contact 31A is grounded, the conductive contact 31B is not grounded, the detection electrode 100 connected to the conductive contact 31B is not grounded, and a voltage difference is formed between the conductive contact 31A and the conductive contact 31B.
Further, by means of the voltage difference, it can be further determined whether the solution tank 300 is loaded in place, taking the solution tank 300 as a recycling bin as an example, the conductive contact 31A is grounded, the conductive contact 31B is not grounded, when the recycling bin is loaded on the machine body 50, the main control system is grounded due to the electrical connection with the conductive contact 31A and the conductive contact 31B, and receives the grounded zero voltage signal, thereby determining that the recycling bin is loaded in place, otherwise, determining that the recycling bin is not in place, and reminding the user of loading the recycling bin is needed. When the recycling bin is not loaded or not loaded in place, the machine body 50 cannot be started or does not work after being started.

When the two detection electrodes 100 are immersed in water at the same time, the detection electrodes 100 and the machine body 50 of the cleaning machine form a communication loop through the conductive contacts 31 on the upper cover 30, a water full signal is transmitted to a main control system in the machine body 50, and the main control system recognizes that the solution barrel 300 is in a water full state, so that the whole machine of the cleaning machine is controlled to stop. It should be noted that, the water-full state described herein does not necessarily mean that the space in the solution tank 300 is filled with water, but may also mean that the liquid level in the solution tank 300 is raised to a certain height, for example, the liquid level is raised to a position where the liquid level contacts both the detection electrodes 100, that is, the water-full state.

The water flow is limited by the shape of the water inlet pipe 42 so as not to be in direct contact with the sensing electrode 100, thereby avoiding direct contact of the water flow with the sensing electrode 100.
