Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of floor cleaning machines, in particular to a liquid level detection control method and liquid level detection mechanism of a floor cleaning machine. BACKGROUND

[0002] With people's life becoming more and more intelligent, different cleaning products appear, and the floor cleaning machine integrates sweeping and mopping into one, which is very convenient and is loved by the public. During use of the floor cleaning machine, the sewage on the ground needs to be sucked into the liquid storage tank, and when the liquid level in the liquid storage tank reaches a preset liquid level line, the liquid full alarm of the liquid storage tank is triggered and the floor cleaning machine stops working. At present, the way to detect the liquid full of the liquid storage tank on the market generally uses two electrode sheets to detect, and when the liquid level in the liquid storage tank reaches the preset liquid level line, the two electrode sheets form a path under the conductive action of water to trigger the liquid level reminder. However, when the liquid entering the liquid storage tank has a large viscosity, such as soy sauce and edible oil commonly seen in the kitchen, the solution with large viscosity adheres to the inner wall of the liquid storage tank, and when the liquid level does not reach the preset liquid level line, the two electrode sheets may be conducted through the solution adhering to the inner wall of the liquid storage tank, and the liquid level reminder is mistakenly triggered, which affects the normal use of the floor cleaning machine. SUMMARY

[0003] The present application provides a liquid level detection control method and liquid level detection mechanism of a floor cleaning machine, which is used to avoid mistakenly triggering the liquid level reminder when the liquid level in the liquid storage tank does not reach the preset liquid level line, and affecting the normal use of the floor cleaning machine.

[0004] In a first aspect, the present application provides a liquid level detection control method, which comprises the following steps:

[0005] According to whether a first loop formed between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank is conductive, or according to whether the first loop formed between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank is conductive and whether a second loop formed between the first probe and the third probe located on the same inner wall surface of the liquid storage tank is conductive, it is determined whether the liquid level in the liquid storage tank reaches the preset liquid level line.

[0006] In one embodiment, according to whether a first loop formed between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank is conductive, it is determined whether the liquid level in the liquid storage tank reaches the preset liquid level line, which comprises the following steps:

[0007] A voltage is applied between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank;

[0008] It is determined whether a first loop formed between the first probe and the second probe is conductive;

[0009] If yes, it is determined that the liquid level in the liquid tank reaches the preset liquid level line, and the liquid tank is not working;

[0010] Otherwise, it is determined that the liquid level in the liquid tank does not reach the preset liquid level line, and the liquid tank remains in the normal working state.

[0011] In one embodiment, whether the liquid level in the liquid tank reaches the preset liquid level line is determined according to whether a first loop between the first probe and the second probe located on different inner wall surfaces of the liquid tank is formed and whether a second loop between the first probe and the third probe located on the same inner wall surface of the liquid tank is formed, including the following steps:

[0012] A voltage is applied between the first probe and the second probe located on different inner wall surfaces of the liquid tank, and a voltage is applied between the first probe and the third probe located on the top wall surface of the liquid tank;

[0013] If the second loop between the first probe and the third probe is formed, and the first loop between the first probe and the second probe is not formed, it is determined that the liquid level in the liquid tank does not reach the preset liquid level line, and the inner wall of the liquid tank has viscous liquid and / or the first loop has a fault;

[0014] If the second loop between the first probe and the third probe is formed, and the first loop between the first probe and the second probe is formed, it is determined that the liquid level in the liquid tank reaches the preset liquid level line, and the liquid tank is not working.

[0015] In one embodiment, the following steps are further included: when it is determined that the inner wall of the liquid tank has viscous liquid and / or the first loop has a fault, a signal for controlling the sweeper to increase the suction force is outputted and / or a maintenance signal is outputted.

[0016] In a second aspect, the present application provides a control device for implementing the above-mentioned liquid level detection control method, comprising:

[0017] A voltage module for applying a voltage between the first probe and the second probe located on different inner wall surfaces of the liquid tank; and

[0018] A judgment module for judging whether a first loop between the first probe and the second probe is formed.

[0019] In a third aspect, the present application provides a liquid level detection mechanism, which is arranged in a liquid storage tank. The liquid level detection mechanism comprises a first probe and a second probe arranged on different inner wall surfaces of the liquid storage tank. The first probe and the second probe are configured to form a first circuit through liquid when the liquid level in the liquid storage tank reaches a preset liquid level line. Alternatively, the first probe and the second probe are configured such that when the liquid level in the liquid storage tank reaches the preset liquid level line, the first probe and the second probe do not form a first circuit, but the first probe and a third probe arranged on the same inner wall surface as the first probe form a second circuit.

[0020] In one embodiment, the top wall of the liquid storage tank has a protruding structure protruding towards the bottom of the liquid storage tank. The first probe and the third probe are arranged on the protruding structure. In this embodiment, the first probe and the third probe are arranged with a gap between them and the second probe. The length of the circuit formed is increased, and the circuit is less likely to be formed when viscous solution adheres to the inner wall of the liquid storage tank, thereby avoiding false triggering of the signal.

[0021] In one embodiment, the number of protruding structures is two, and the first probe and the third probe are arranged on the two protruding structures, respectively. In this embodiment, the first probe and the third probe are arranged with a gap between them. When viscous solution adheres to the protruding structure, the circuit can be formed. When the first circuit is conductive and the second circuit is not conductive, it can be determined that the inner wall of the liquid storage tank has viscous solution.

[0022] In one embodiment, the second probe is arranged on the side wall of the liquid storage tank, and the first probe is arranged on the top wall of the liquid storage tank and located away from the side wall where the second probe is arranged. In this embodiment, the protruding structure is arranged suspended on the inner wall of the liquid storage tank, further increasing the distance between the second probe and the first probe and the third probe, and increasing the length of the circuit that can be formed.

[0023] In one embodiment, the distance from the first probe to the bottom of the liquid storage tank is equal to the distance from the third probe to the bottom wall of the liquid storage tank, and the distance from the first probe to the bottom of the liquid storage tank is greater than the distance from the second probe to the bottom of the liquid storage tank. In this embodiment, when the liquid level reaches the preset liquid level line, the first probe and the third probe can be conductive with the second probe through the conductive effect of water. When sewage enters the liquid storage tank, the liquid level gradually rises, and the sewage first submerges the second probe and then contacts the first probe and the third probe. The second circuit is conductive after the first circuit, and the viscous solution does not conduct the second circuit, thereby avoiding false reporting when the liquid level has not reached the preset liquid level line.

[0024] In one embodiment, the distance from the second probe to the first probe is greater than or equal to the distance from the second probe to the third probe. By this embodiment, the distance between the second probe and the first probe and the third probe is guaranteed to be at the optimal position, and the length of the path capable of forming a loop is increased.

[0025] In a fourth aspect, the present application provides a scrubber comprising the liquid level detection mechanism as described above.

[0026] Compared with the prior art, the present application has the following advantages:

[0027] The first probe and the second probe are located on different inner wall surfaces in the liquid tank, so that the first probe and the second probe cannot form a loop through the viscous solution attached to the inner wall of the liquid tank, and the first probe and the third probe are located on the same inner wall surface. When the first loop formed by the first probe and the second probe is conductive, it can be determined that the liquid level in the liquid tank reaches the preset liquid level line; when the first loop is not conductive and the second loop formed by the first probe and the third probe is conductive, it can be determined that the liquid level in the liquid tank does not reach the preset liquid level line, and the inner wall of the liquid tank has a viscous solution and / or the first loop is faulty; and the situation of misjudging that the liquid level reaches the liquid level line is avoided.

[0034] The present application will be further described below with reference to the accompanying drawings.

[0035] Example 1

[0036] The present application provides a liquid level detection control method, comprising the following steps:

[0037] According to whether a first loop formed between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank is conductive, or according to whether the first loop formed between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank is conductive and whether a second loop formed between the first probe and the third probe located on the same inner wall surface of the liquid storage tank is conductive, whether the liquid level in the liquid storage tank reaches a preset liquid level line is determined.

[0038] Specifically, when the first loop is conductive, whether the second loop is conductive or not, it can be determined that the liquid level in the liquid storage tank reaches the preset liquid level line; when the first loop is not conductive, and the second loop is conductive, it is determined that the liquid level in the liquid storage tank does not reach the preset liquid level line, and the inner wall of the liquid storage tank is attached with a viscous solution to make the second loop conductive.

[0039] Further, the scrubber is generally provided with an infrared dirt sensor, which can be used to detect the dirt degree of the ground. Due to different dirt degrees of the ground, the suction force and the water volume are adaptively adjusted, and the display ring also changes from blue to red, indicating the dirt degree. The infrared dirt sensor can detect the particulate matter on the ground to show dirt, and currently a small amount of soy sauce stains can be identified as dirt, so as to control the water volume and suction force to be increased to clean the soy sauce, and the soy sauce is sucked into the sewage tank, and a small amount of clean water is not identified.

[0040] However, the infrared dirt sensor has the following two problems: ①The detection parameter is too sensitive, and a small amount (for example, about 6g) of soy sauce and clean water can trigger the infrared sensor. ②If the sensitivity of the infrared dirt sensor is adjusted to be weaker, a large amount of clean water and a small amount of soy sauce cannot be identified at the same time, and it is difficult to identify the existence of dirt at the same time when a small amount of soy sauce and a large amount (for example, about 200g) of clean water are needed. Generally, the loop formed by the first probe and the third probe is only conductive when the liquid level reaches the preset liquid level line. However, when the inner wall of the liquid storage tank is attached with a viscous liquid such as soy sauce, the loop may also be conductive. Therefore, when the second loop is conductive and the first loop is not conductive, it can be determined that there is a viscous liquid or a large amount of clean water on the ground. The second scheme can be selected to cooperate with this detection and judgment to increase the suction force, so as to ensure that the viscous liquid can be sucked into the liquid storage tank, and the viscous liquid can be cleaned, which can solve the problem.

[0041] Embodiment 2

[0042] According to whether a first loop formed between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank is conductive, whether the liquid level in the liquid storage tank reaches a preset liquid level line is determined, comprising the following steps:

[0043] S10, a voltage is applied between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank.

[0044] S20, whether a first loop formed between the first probe and the second probe is conductive is determined.

[0045] S30, if the first probe and the second probe form a conductive first loop, it is determined that the liquid level in the liquid tank reaches the preset liquid level line, and the liquid tank does not work.

[0046] S40, if the first probe and the second probe do not form a conductive first loop, it is determined that the liquid level in the liquid tank does not reach the preset liquid level line, and the liquid tank remains in a normal working state.

[0047] Embodiment 3

[0048] According to whether a conductive first loop is formed between the first probe and the second probe located on different inner wall surfaces of the liquid tank and whether a conductive second loop is formed between the first probe and the third probe located on the same inner wall surface of the liquid tank, it is determined whether the liquid level in the liquid tank reaches the preset liquid level line, comprising the following steps:

[0049] S10, an electric voltage is applied between the first probe and the second probe located on different inner wall surfaces of the liquid tank, and an electric voltage is applied between the first probe and the third probe located on the top wall surface of the liquid tank.

[0050] S20, if the second loop is formed between the first probe and the third probe, and the first loop is not formed between the first probe and the second probe, it is determined that the liquid level in the liquid tank does not reach the preset liquid level line, and the inner wall of the liquid tank has a viscous liquid and / or the first loop has a fault.

[0051] S20 comprises the following sub-steps:

[0052] S21, outputting a signal for controlling the scrubber to increase the suction force and / or outputting a maintenance signal.

[0053] Specifically, the maintenance signal is used to clean the viscous solution attached to the inner wall of the liquid tank, or to check whether the first loop is conductive, preferably to check whether the second probe is rusted. To check whether the first loop is conductive, a solution can be injected into the liquid tank. When the liquid level of the solution reaches the preset liquid level line, if the first loop is not conductive and the second loop is conductive, it is proved that the first loop has a fault.

[0054] S30, if the second loop is formed between the first probe and the third probe, and the first loop is formed between the first probe and the second probe, it is determined that the liquid level in the liquid tank reaches the preset liquid level line, and the liquid tank does not work.

[0055] Embodiment 4

[0056] The application provides a control device for implementing the above-mentioned liquid level detection control method, comprising:

[0057] a voltage module for applying a voltage between the first probe and the second probe located on different inner wall surfaces of the liquid storage tank; and

[0058] a judgment module for judging whether a first loop is formed between the first probe and the second probe.

[0059] Embodiment 5

[0060] The present application provides a liquid level detection mechanism, which is arranged in a liquid storage tank 40. The liquid level detection mechanism comprises a first probe 10 and a second probe 20 arranged on different inner wall surfaces of the liquid storage tank 40 respectively. The first probe 10 and the second probe 20 are configured to form a first loop through liquid when the liquid level in the liquid storage tank 40 reaches a preset liquid level line. Alternatively, the first probe 10 and the second probe 20 are configured not to form a first loop when the liquid level in the liquid storage tank 40 reaches the preset liquid level line, but a second loop is formed between the first probe 10 and a third probe 30 on the same inner wall surface as the first probe 10 in the liquid storage tank 40.

[0061] Specifically, the liquid storage tank 40 is cylindrical or square. The first probe 10 is arranged on the upper end inner wall of the liquid storage tank 40, and the second probe 20 is arranged on the bottom wall or the side wall of the liquid storage tank 40, preferably on the side wall of the liquid storage tank 40. The distance between the first probe 10 and the second probe 20 in the vertical direction is between one fourth and one third of the height of the liquid storage tank 40. The position of the first probe 10 is the preset liquid level line. When the liquid level reaches the preset liquid level line, the first probe 10 and the second probe 20 are connected through the sewage. When the first loop is connected, whether the second loop is connected or not, it can be determined that the liquid level in the liquid storage tank 40 reaches the preset liquid level line, so that the scrubber is stopped working until the liquid in the liquid storage tank 40 is discharged and the scrubber is restarted. When the first loop is not connected and the second loop is connected, it is determined that the liquid level in the liquid storage tank 40 does not reach the preset liquid level line. The inner wall of the liquid storage tank 40 is attached with viscous solution, so that the second loop is connected. At this time, the scrubber still maintains the working state, and it can be determined that the inner wall of the liquid storage tank 40 is attached with viscous solution. At this time, the suction force of the scrubber is increased or the first loop is stopped for maintenance to determine whether it is faulty or the viscous solution attached to the inner wall of the liquid storage tank 40 is cleaned, so that the viscous solution such as soy sauce and edible oil commonly used in kitchens can be sucked into the liquid storage tank 40.

[0062] Further, in one extreme case, when the liquid level reaches the preset liquid level line and the first loop is not connected while the second loop is connected, the liquid storage tank 40 is preferably transparent, so that the liquid level in the liquid storage tank 40 can be judged by the maintenance personnel, which is convenient for them to judge whether the first loop is faulty.

[0063] Embodiment 6

[0064] This embodiment is further optimized on the basis of embodiment 5 as follows: as Figure 1 , the first probe 10 is arranged on the top wall of the liquid tank 40, and the top wall of the liquid tank 40 is also provided with a third probe 30 capable of forming a second circuit with the first probe 10 through liquid. When the first circuit is conducted, it indicates that the liquid level in the water tank reaches the preset liquid level line. When the first circuit is not conducted and the second circuit is conducted, it indicates that the liquid level in the water tank does not reach the preset liquid level line, and the inner wall of the water tank is attached with viscous liquid to make the second circuit conducted.

[0065] Specifically, the first probe 10 and the third probe 30 are both located on the top of the liquid tank 40. When viscous solution adheres to the inner wall of the liquid tank 40, such as soy sauce or edible oil, the first probe 10 and the second probe 20 are more likely to be conducted through the viscous solution than the first probe 10 and the second probe 20. That is, when both the first circuit and the second circuit are conducted, it indicates that the liquid level in the water tank reaches the preset liquid level line, at which time the scrubber can be controlled to stop working; when the first circuit is not conducted and the second circuit is conducted, it indicates that the liquid level in the water tank does not reach the preset liquid level line, and the inner wall of the water tank is attached with viscous liquid to make the second circuit conducted, at which time the scrubber remains in working state and the suction force is increased to ensure that the viscous solution on the ground can be sucked into the liquid tank 40.

[0066] Embodiment 7

[0067] This embodiment is further optimized on the basis of embodiment 6 as follows: the top wall of the liquid tank 40 has a protruding structure 50 protruding towards the bottom of the liquid tank 40, and the first probe 10 and the third probe 30 are arranged on the protruding structure 50. By arranging the protruding structure 50, the first probe 10 and the third probe 30 have a gap between them and the second probe 20, which increases the distance of the circuit formed and makes it difficult to form a circuit when viscous solution adheres to the inner wall of the liquid tank 40, thereby avoiding the false touch signal.

[0068] The number of protruding structures 50 is two, and the first probe 10 and the third probe 30 are arranged on the two protruding structures 50 respectively. The first probe 10 and the third probe 30 have a certain gap therebetween, and when viscous solution adheres to the protruding structure 50, a circuit can be formed. When the first circuit is conducted and the second circuit is not conducted, it can be determined that the inner wall of the liquid tank 40 has viscous solution.

[0069] The second probe 20 is arranged on the side wall of the liquid storage tank 40, and the first probe 10 is arranged on the top wall of the liquid storage tank 40 and is located away from the side wall where the second probe 20 is arranged. The protruding structure 50 is arranged in a suspended manner on the inner wall of the liquid storage tank 40, further increasing the distance between the second probe 20 and the first probe 10 and the third probe 30, and increasing the length of the path capable of forming a loop.

[0070] Specifically, by arranging the protruding structure 50, the protruding structure 50 facilitates the installation of the first probe 10 and the third probe 30 on the protruding structure 50, and facilitates the fixing of the relative height of the first probe 10 and the third probe 30 in the liquid storage tank 40. By means of the protruding structure 50, the first probe 10 and the third probe 30 can be arranged in a suspended manner inside the liquid storage tank 40, and the distance from the first probe 10 and the third probe 30 to the second probe 20 along the inner wall of the liquid storage tank 40 is increased. When the viscous solution adheres to the inner wall of the liquid storage tank 40, the difficulty of conducting the first probe 10 and the second probe 20 and the second probe 20 and the third probe 30 through the viscous solution is increased, and the situation that the liquid level in the liquid storage tank 40 does not reach the preset liquid level line, but the viscous solution adhering to the inner wall of the liquid storage tank 40 causes the first probe 10 and the second probe 20 or the second probe 20 and the third probe to conduct, and the situation that the liquid level is mistakenly considered to reach the preset liquid level line is avoided.

[0071] Embodiment 8

[0072] As Figure 2 , this embodiment is a further optimization based on embodiment 6, and the distance from the first probe 10 to the bottom wall of the liquid storage tank is equal to the distance from the third probe 30 to the bottom wall of the liquid storage tank, i.e. L1=L3. When the liquid level reaches the preset liquid level line, the first probe 10 and the third probe 30 can both conduct with the second probe 20 through the conductive effect of water.

[0073] The distance L5 from the second probe 20 to the first probe 10 is greater than or equal to the distance L4 from the second probe 20 to the third probe 30. The distance between the second probe 20 and the first probe 10 and the third probe 30 is ensured to be at an optimal position, and the length of the path capable of forming a loop is increased.

[0074] Specifically, when the second probe 20 is located on the center line between the first probe 10 and the third probe 30, the distance between the second probe 20 and the first probe 10 and the third probe 30 is equal. When the second probe 20 is close to the first probe 10, the distance between the second probe 20 and the third probe 30 is greater than the distance between the second probe 20 and the first probe 10, and vice versa.

[0075] The distance between the first probe 10 and the third probe 30 and the bottom of the liquid tank 40 is greater than the distance between the second probe 20 and the bottom of the liquid tank 40, i.e. L1=L3>L2. When the sewage enters the liquid tank 40, the liquid level gradually rises, and the sewage first submerges the second probe 20, and then contacts the first probe 10 and the third probe 30. The second circuit is turned on later than the first circuit, so as to avoid that the viscous solution turns on the second circuit and causes false reporting when the liquid level has not reached the preset liquid level line.

[0076] Embodiment 9

[0078] Although the present application has been described with reference to the preferred embodiments, various modifications can be made to it without departing from the scope of the present application and equivalent components can be substituted therefor. In particular, each of the technical features mentioned in each of the embodiments can be combined in any manner as long as there is no structural conflict.
