Description

Technical Field

[0001] The present application relates to the field of cleaning technology, and in particular to a turbidity detection component, a base station and a cleaning device. Background Art

[0002] Nowadays, cleaning equipment including sweeping robots are gradually entering thousands of households as representative products of smart homes, but poor cleaning effect has always been its core pain point, seriously restricting the promotion of the cleaning equipment.

[0003] As we all know, the ability and reliability of detecting dirt on the ground has a great impact on the actual cleaning effect. For example, if the sweeping robot can detect which areas are dirty and the degree of dirt in different areas, it can adjust the number of cleaning times and time for different areas and different degrees of dirt to achieve better cleaning effect and efficiency.

[0004] At present, the technical solution for detecting the degree of dirtiness is to set a turbidity detector on the cleaning device. The degree of dirtiness is determined by detecting the turbidity of the sewage generated by the cleaning parts of the sweeping robot through the turbidity detector. The higher the degree of dirtiness on the ground, the higher the turbidity of the dirtiness. Conversely, the lower the degree of dirtiness on the ground, the lower the turbidity of the dirtiness in the pipe.

[0005] However, technicians have found that when sewage passes through the pipeline of the cleaning equipment, the dirt in the sewage will be deposited on the detection component of the turbidity detector for detecting turbidity. As time goes by, more and more dirt accumulates, which will cause the turbidity detector to reduce the detection accuracy of sewage turbidity or even fail. Utility Model Content

[0026] In order to solve the problem that the dirt in the sewage causes the turbidity detector to reduce the accuracy of turbidity detection, the inventor of the present application has the idea of ​​setting a cleaning component, using the cleaning component to clean the deposited dirt, so that there is no dirt affecting the accuracy of the turbidity detector, so that the accuracy of the turbidity detection of the turbidity detector will not decrease, and will not fail. As follows, in conjunction with the relevant drawings, the structure of the turbidity detection component of the present application is described.

[0027] See also Figure 1 , Figure 2 and Figure 3 The present application discloses a turbidity detection assembly 10. The turbidity detection assembly 10 comprises a connecting pipe 1, a turbidity detector 2 and a cleaning assembly 3. The connecting pipe 1 is for sewage to flow through, and its structure is not limited to a through rectangular parallelepiped as shown in the figure, but can also be a through cylindrical shape, etc. Figure 2 Combined with Figure 2, the turbidity detector 2 is arranged in the connecting pipe, and is used to detect the turbidity of the sewage passing through the connecting pipe. Based on this, the structure of the turbidity detector 2 is not limited, as long as it can detect the turbidity. In an embodiment of the present application, the turbidity detector includes a first component 21 and a second component 22 arranged inside the connecting pipe 1. The arrangement inside the connecting pipe 1 mainly means that the part of the first component 21 that transmits the signal and the part of the second component 22 that receives the signal are located inside the connecting pipe 1, and the other parts can be located inside the connecting pipe 1 or outside the connecting pipe 1. The turbidity detector 2 generates a detection signal for reflecting the turbidity according to the signal transmitted between the first component 21 and the second component 22. In this embodiment, the signal transmitted between the first component 21 and the second component 22 is an optical signal, that is, the first component 21 emits light, and the light is received by the second component 22 after passing through the sewage inside the connecting pipe 1, so that the second component 22 generates a detection signal. In other embodiments, the signal transmitted between the first component 21 and the second component 22 may be a current signal (for example, the first component 21 and the second component 22 are electrodes, and the turbidity is tested by testing the conductivity), or may be a sound wave signal. In addition, based on the inspiration that the first component 21 and the second component 22 transmit light signals, in other embodiments, the first component 21 and the second component 22 may be arranged outside the connecting tube 1, as long as the light passes through the tube wall of the connecting tube 1 to achieve signal transmission, that is, the turbidity detector 2 includes the first component 21 and the second component 22 arranged outside the connecting tube 1. The turbidity detector 2 is based on the signal transmitted between the first component 21 and the second component 22 (the signal may be a signal transmitted in the connecting tube, such as the aforementioned current signal or light signal, or a signal passing through the connecting tube, such as the aforementioned light signal). The turbidity detector is used to detect the turbidity of the sewage passing through the connecting pipe 1 in two cases: 1) the turbidity detector can obtain the turbidity by itself; 2) the turbidity detector cannot obtain the turbidity, but generates a detection signal for reflecting the turbidity. After the detection signal is transmitted, other components obtain the turbidity of the sewage according to the detection signal. In short, the structure of the turbidity detector 2 is not limited, as long as it can detect the turbidity of the sewage passing through the connecting pipe 1.

[0028] Continue to see Figure 1 , Figure 2 and Figure 3, the cleaning component 3 is arranged on the connecting tube 1, and is used to clean the inner wall of the connecting tube and / or the turbidity detector. Based on this, the structure of the cleaning component 3 is not limited to the structure described later, and it is sufficient to clean the inner wall of the connecting tube and / or the turbidity detector. In an embodiment of the present application, the turbidity detector includes a first component 21 and a second component 22. In the case where the first component 21 and the second component 22 are arranged inside the connecting tube 1, the cleaning component 3 cleans the dirt on the first component 21 and the second component 22, so that the dirt does not affect the transmission of the signal between the first component 21 and the second component 22, thereby ensuring that the detection accuracy of the turbidity detector will not decrease. For example, in an embodiment of the present application, the first component 21 and the second component 22 transmit optical signals, at least cleaning the dirt on the respective light-transmitting components of the first component 21 and the second component 22, so that the light emitted by the first component 21 can be received by the second component 22. When the first component 21 and the second component 22 are electrodes for transmitting electrical signals, dirt on the electrodes is cleaned. After the dirt is removed, the dirt will not affect the current between the first component 21 and the second component 22.

[0029] Based on the above technical inspiration of cleaning away dirt without affecting the signal transmission between the first component 21 and the second component 22, when the first component 21 and the second component 22 are arranged outside the connecting tube 1 and the signal passes through the connecting tube 1, the cleaning component 3 cleans the dirt on the inner wall of the connecting tube 1 corresponding to the first component 21 and the second component 22, so that the dirt will not affect the passage of the signal emitted by the first component 21, and the signal will not be attenuated due to the dirt, thereby ensuring that the detection accuracy of the turbidity detector will not decrease.

[0030] As configured above, since the cleaning component is disposed on the connecting pipe and is used to clean the inner wall of the connecting pipe and / or the turbidity detector, as the use time of the turbidity detection component 10 increases, the inner wall of the connecting pipe 1 (at least corresponding to the dirt on the first component 21 and the second component 22) and / or the dirt on the turbidity detector (at least on the first component 21 and the second component 22) are cleaned by the cleaning component 3 (for example, in the subsequent description, the cleaned dirt is brought into the sewage tank along with the sewage flowing in the connecting pipe 1), and thus, there is no dirt that affects the detection accuracy of the turbidity detector 2, that is, as the use time increases, the detection accuracy of the turbidity detector 2 will not decrease, let alone fail.

[0031] In some embodiments, the cleaning component 3 includes an ultrasonic component. The ultrasonic component includes a vibrating component (not shown in the figure). In this case, the vibrating component is a component in the ultrasonic component that emits ultrasonic waves. The cleaning component 3 emits ultrasonic waves, so that the dirt on the inner wall of the connecting pipe 1 corresponding to the area of ​​the first component 21 and the area corresponding to the second component 22 is subjected to strong impact and vibration. Under the action of ultrasonic waves, these dirt will gradually loosen and eventually be washed away by the sewage flowing in the connecting pipe 1 (for example, brought into the sewage tank later), so as to achieve the purpose of cleaning the area corresponding to the first component 21 and the area of ​​the second component 22 on the inner wall of the connecting pipe 1, so that the signal emitted by the first component 21 can be received by the second component 22. Of course, in the case where the first component 21 and the second component 22 are arranged inside the connecting pipe 1, ultrasonic waves can also clean the dirt on the first component 21 and the second component 22.

[0032] The vibrating component is attached to the connecting pipe 1. In this way, dirt on the inner wall of the connecting pipe 1 (at least corresponding to the first component 21 and the second component 22) is cleaned by vibration, and / or dirt on the turbidity detector (at least the first component 21 and the second component 22) is cleaned by vibration.

[0033] As described above, ultrasonic waves are used to clean dirt on the inner wall of the connecting tube 1 (at least dirt on the area corresponding to the first component 21 and the area corresponding to the second component 22), and / or dirt on the turbidity detector (at least dirt on the first component 21 and the second component 22 in the connecting tube 1), and the cleaning effect is good, which can ensure that the detection accuracy of the turbidity detector 2 will not decrease. Of course, as mentioned above, it is also convenient to set the ultrasonic component because the ultrasonic component can be set outside the connecting tube 1. The convenient setting includes the assembly between the ultrasonic component and the connecting tube 1, the installation position or routing of the ultrasonic component, etc.

[0034] See also Figure 3 Combined with Figure 1 and Figure 2 , when the first component 21 and the second component 22 are arranged inside the connecting pipe 1, the ultrasonic component, the first component 21 and the second component 22 are arranged around the circumference of the connecting pipe 1. On the projection of a plane parallel to the flow direction of the sewage in the connecting pipe, the area where the ultrasonic component fits the connecting pipe 1 and the area of ​​the inner wall of the connecting pipe 1 corresponding to the first component 21 and the second component 22 at least partially overlap, Figure 3 Indicated in Figure 1The projection surface from the right side of the drawing to the left side completely overlaps, and the width of the overlapping portion is D. Of course, the at least partial overlap also includes staggering. That is, in this case, a section perpendicular to the flow direction of the sewage will pass through the fitted area, the first component and the second component. Of course, the technicians can understand that when the first component 21 and the second component 22 are arranged outside the connecting pipe 1, the area where the ultrasonic component fits the connecting pipe and the area of ​​the inner wall of the connecting pipe 1 corresponding to the first component 21 and the second component 22 at least partially overlap. Similarly, in this case, a section perpendicular to the flow direction of the sewage will pass through the fitted area, the first component and the second component.

[0035] As set up as above, due to the flow direction of the sewage in the connecting pipe 1, that is, along the direction indicated by the arrow A, the area where the ultrasonic component is in contact with the connecting pipe 1 and the area where the inner wall of the connecting pipe corresponds to the first component 21 and the second component 22 at least partially overlap, so that when cleaning the dirt by vibration, the distance between the ultrasonic component and the first component 21 and the second component 22 is relatively close, and thus, the ultrasonic component can clean (vibrate away) the dirt with less power, and the power consumption of the turbidity detection component is low.

[0036] As an alternative to the above-mentioned cleaning of dirt by vibration, the cleaning assembly 3 includes a driving member and a scraper arm located in the connecting tube 1. In the case where the first component 21 and the second component 22 are arranged outside the connecting tube 1, the scraper arm is in frictional contact with the inner wall of the connecting tube and is driven by the driving member to scrape off the dirt, so as to achieve the cleaning of the inner wall of the connecting tube 1. In the case where the first component 21 and the second component 22 are arranged inside the connecting tube 1, the scraper arm is in frictional contact with both the first component 21 and the second component 22 to scrape off the dirt, so as to achieve the cleaning of the turbidity detector. The scraper arm may include two arms, the first component 21 is in frictional contact with one arm, and the second component 22 is in frictional contact with the other arm. This frictional contact to remove dirt can be understood by using the wiper to remove dirt from the windshield.

[0037] As described above, by rotating the scraper arm in the connecting tube 1, the inner wall of the connecting tube 1 is cleaned (at least the area corresponding to the first component 21 and the area corresponding to the second component 22 are in frictional contact to clean away dirt), or the turbidity detector is cleaned (for example, at least the first component 21 and the second component 22 are in frictional contact to scrape away dirt on the first component 21 and the second component 22 to clean), thereby ensuring that the detection accuracy of the turbidity detector 2 does not decrease.

[0038] See also Figure 1 Combined with Figure 2 and Figure 3 In the case where the first component 21 and the second component 22 are arranged outside the connecting pipe, the first component 21 is a light emitting component and the second component 22 is a light receiving component. Of course, in the case where the first component 21 and the second component 22 are arranged inside the connecting pipe 1, the first component 21 can also be a light emitting component and the second component 22 can also be a light receiving component. Regardless of how they are arranged, it is sufficient that the light can pass through the sewage in the connecting pipe 1 to finally detect the turbidity of the sewage.

[0039] As configured above, the turbidity detector 2 can judge the turbidity by the characteristics of the light (such as light intensity, refractive index, etc.). In this case, the dirt on the inner wall of the connecting tube 1 (at least the area corresponding to the first component 21 and the area of ​​the second component 22 on the connecting tube 1) and / or the dirt on the turbidity detector (at least the dirt on the first component 21 and the second component 22) is cleaned by the cleaning component 3, so that the propagation of light is not affected by the dirt, and further, it can be ensured that the detection accuracy of the turbidity detector 2 will not decrease.

[0040] See also Figure 4 Combined with Figure 5 In the second aspect, the present application discloses a base station 100. The base station 100 includes any of the above-mentioned turbidity detection components 10, a cleaning mechanism 20, a sewage tank 30 and an air pump 40. Under the action of the air pump 40, the sewage in the cleaning mechanism 20 flows into the sewage tank 30 through the connecting pipe 1. One connection method of how to flow into the sewage tank 30 is as follows: the cleaning mechanism 20, the connecting pipe 1 of the turbidity detection component 10, the sewage tank 30 and the air pump 40 are connected in series in sequence. More specifically: the two ends of the connecting pipe 1 have a first connecting section 11 and a second connecting section 12 respectively. The first connecting section 11 is connected to the cleaning mechanism 20 through a pipeline, and the second connecting section 12 is connected to the sewage tank 30. In one embodiment of the present application, the base station also includes a controller, which is connected to the air pump 40, and is also connected to the first component 21 and the second component 22, and receives the detection signal. In this way, the controller obtains the turbidity of the sewage according to the detection signal. In addition, the base station further includes a clean water tank 50 , a three-way pipe 60 , a first one-way valve 71 , a second one-way valve 72 , a water injection port 80 and a clean water pump 90 .

[0041] The base station is used in conjunction with the sweeping robot. Combined with the accompanying drawings and the components of the aforementioned base station, the working process of the base station in one embodiment of the present application is described as follows:

[0042] 1) Cleaning the floor and cleaning the mop of the sweeping robot: The water in the clean water tank 50 is converted through the three-way pipe 60 (one way is the water injection route, and the other way is the cleaning mechanism route). When the sweeping robot needs to add water, the water pump (not shown) works, the first one-way valve 71 and the second one-way valve 72 are closed, and the clean water in the clean water tank 50 enters the water tank of the sweeping robot through the three-way pipe 60, the first one-way valve 71, and the water injection port 80, completing the water adding action. The added water is used by the sweeping robot to clean the floor and other cleaning objects. When the cleaning parts (such as mops) of the sweeping robot need to be cleaned, the clean water pump 90 works, the second one-way valve 72 is opened, the first one-way valve 71 is closed, and the clean water in the clean water tank 50 reaches the cleaning mechanism 20 through the three-way pipe 60, the second one-way valve 72, and the clean water pump 90, and the cleaning parts (such as mops) are cleaned by the cleaning mechanism 20. How to be cleaned is not limited, for example, the cleaning parts are rotated and collide with other parts or are washed by the water in the cleaning mechanism 20 and cleaned.

[0043] 2) Sewage transportation: When the base station completes the cleaning action of the cleaning element (mop), the air pump 40 starts to work and the sewage tank 30 begins to be vacuumed. In this way, the sewage in the cleaning mechanism 20 passes through the connecting pipe 1 of the turbidity detection component 10 and reaches the sewage tank 30.

[0044] 3) Turbidity detection: Take the detection of turbidity by optical signal as an example: when the sewage flows from the cleaning mechanism 20 through the connecting pipe 1 to the sewage tank 30, the first component 21 sends out an optical signal and the second component 22 receives the optical signal. When the degree of dirtiness of the sewage is different, the turbidity will be different, and the loss of light when passing through will be different. Therefore, the intensity of the optical signal received by the second component 22 is different, so the controller can judge the turbidity of the sewage according to the intensity.

[0045] 4) Cleaning of dirt (i.e., cleaning of the connecting tube 1): Cleaning of dirt with optical signals Description: When sewage passes through the connecting tube 1, dirt will be deposited on the inner wall of the connecting tube 1. As time accumulates, the deposits will become more and more, thereby affecting the light transmittance, and then affecting the detection accuracy, or even failure. While passing sewage, the cleaning component 3 can be started to complete the self-cleaning of the inner wall of the connecting tube 1 through the high-frequency vibration of ultrasound (of course, when the first component 21 and the second component 22 of the turbidity detector 2 are located inside the connecting tube 1, the ultrasound can pass through the inner wall of the connecting tube 1 and act on the first component 21 and the second component 22), thereby restoring the accuracy and performance of the turbidity detector 2. Of course, cleaning dirt while passing sewage can allow the dirt to be taken away with the sewage. Therefore, in other embodiments, the dirt may not be cleaned when passing sewage.

[0046] See also Figure 5 Combined with Figure 4, the cleaning mechanism 20 includes a cleaning pool 201. The sewage tank includes an air inlet and a lever mechanism. The lever mechanism includes a float and a seal. The float bears buoyancy until the seal seals the air inlet. The air pump 40 is connected to the air inlet and is also connected to an exhaust pipe 402, and the exhaust pipe 402 includes an air outlet 401. The air outlet 401 is located above the cleaning pool 201 so that the air discharged from the air outlet 401 blows toward the cleaning pool 201. The working process of the lever mechanism is described as follows: during the operation of the air pump 40, sewage enters the sewage tank 30 from the cleaning pool of the cleaning mechanism through the connecting pipe 1. Because the air pump 40 is connected to the air inlet of the sewage tank 30, air blows toward the cleaning pool from the air outlet 401. In addition, as the water level in the sewage tank 30 rises, the float bears buoyancy. Finally, this buoyancy causes the seal of the lever mechanism to seal the air inlet, and the air pump 40 stops working, and no air is blown out from the air outlet 401.

[0047] As described above, when the lever mechanism is stuck and the seal cannot seal the air inlet even if the float is subjected to buoyancy, the air pump 40 still works. At this time, water will be sucked in from the air inlet by the air pump 40, and the sucked water will be discharged from the air outlet 401 after passing through the exhaust pipe 402 of the air pump. Because the air outlet 401 is located above the cleaning pool 201, the water is directly discharged into the cleaning pool 201 of the cleaning mechanism 20, and will not affect other components, for example, other components will not be rusted due to water, etc. Of course, in some embodiments, the vacuumed air can be discharged from the air outlet 401, which may not be located above the cleaning pool 201.

[0048] In other embodiments, the base station 100 includes a accommodating space 901 for the sweeping robot 200 to enter and exit, the cleaning pool 201 of the cleaning mechanism 20 is located at the bottom of the accommodating space 901, and the air outlet 401 is located at the top of the accommodating space 901 and connected to the accommodating space 901.

[0049] As described above, since the accommodation space 901 is used for the sweeping robot to enter and exit, the accommodation space is usually located at the bottom of the base station. When the air outlet 401 is located at the top of the accommodation space 901 and connected to the accommodation space, the air outlet 401 is relatively far away from the consumer, so that the noise of the base station is small for the consumer. To illustrate the distance, Figure 5 Only the positional relationship between the consumer's ear 902 and the air outlet 401 is illustrated.

[0050] In some embodiments, the connecting pipe 1 is arranged vertically.

[0051] As set up above, since the connecting pipe 1 is placed vertically, the dirt cleaned by the cleaning component 3 will be separated from the inner wall of the connecting pipe 1 or from the first component 21 and the second component 22 of the turbidity detector due to gravity, and can be discharged into the sewage tank 30 together with the sewage, thereby cleaning the dirt more thoroughly and ensuring that the accuracy of the turbidity detector will not decrease.

[0052] Based on the role of the vertical setting, the vertical setting includes the vertical setting when the connecting pipe 1 is straight, and can also be the vertical setting when the connecting pipe 1 includes a U-shaped portion or an S-shaped portion. The vertical setting can be understood as along the height direction of the base station, so that when cleaning dirt, the dirt is separated from the inner wall of the connecting pipe 1 due to gravity or the first component 21 and the second component 22 are separated.

[0053] In a third aspect, the present application discloses a cleaning device. The cleaning device includes any of the aforementioned base stations 100 and a sweeping robot 200. The sweeping robot 200 includes a cleaning member. The structure of the cleaning member is not limited, as long as it can clean the ground and other places. For example, for a household cleaning device, the cleaning member is a mop. The cleaning member is cleaned by the cleaning mechanism. The structure of the cleaning mechanism is not limited, as long as it can clean the cleaning member.

[0054] The above description is only a preferred implementation mode of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
