When the sewage tank 31 is in a negative pressure state, since the air pressure of the external environment is large, garbage such as sewage and dust can be introduced into the sewage tank 31 through the air duct 322, and thus the sewage tank 31 collects the garbage such as sewage and dust.
When the master control circuit 61 receives the shutdown command, the master control circuit 61 delays for a first preset time period and then controls the fan 321 to stop working. For example, after the main control circuit 61 receives the shutdown command, the fan 321 is controlled to stop working after the time delay is 5 seconds, because the clean water supply assembly 400 is directly turned off after the main control circuit 61 receives the shutdown command, which means that no additional clean water is supplied to the rolling brush assembly 500 again, no new sewage is present or added on the ground, and meanwhile, the fan is in time delay working to continuously collect the residual sewage, including the sewage remained in the air duct 322 and the sewage remained on the ground, so that the pollution caused by the residual sewage to the ground is avoided, and the cleaning effect is improved.
In some embodiments, referring to fig. 6, 7 and 8, the garbage collection assembly 300 further includes a first liquid level detection assembly 33, where the first liquid level detection assembly 33 is disposed on the sewage tank 31 and electrically connected to the main control circuit 61 for generating a first liquid level detection signal.
In some embodiments, the first level detection assembly 33 generates a high level first level detection signal when the level of the wastewater in the wastewater tank 31 is greater than or equal to a first preset level threshold. When the liquid level of the sewage tank 31 is less than the first preset height threshold, the first liquid level detection assembly 33 generates a first liquid level detection signal of a low level.
The point different from the above-described embodiment is that the first liquid level detection assembly 33 generates the first liquid level detection signal of the low level when the liquid level of the sewage tank 31 is greater than or equal to the first preset height threshold value. When the liquid level of the sewage tank 31 is less than the first preset height threshold, the first liquid level detection assembly 33 generates a first liquid level detection signal of a high level.
In some embodiments, referring to fig. 9, the first liquid level detecting component 33 includes a probe component 331 and a connector pole piece 332, one end of the probe component 331 is disposed inside the sewage tank 31, the other end of the probe component 331 is electrically connected to the connector pole piece 332, and the connector pole piece 332 is disposed on the sewage tank 31 and electrically connected to the main control circuit 61.
The probe assembly 331 is used for detecting the liquid level inside the sewage tank 31 to generate a first liquid level detection signal. The first preset height threshold may be set according to the distance from the end of the probe assembly 331 to the bottom of the sewage tank 31, for example, the first preset height threshold is the distance from the end of the probe assembly 331 to the bottom of the sewage tank 31, or the first preset height threshold is greater than the distance from the end of the probe assembly 331 to the bottom of the sewage tank 31.
In some embodiments, when the sewage in the sewage tank 31 reaches one end of the probe assembly 331, the connector pole piece 332 and the main control circuit 61 form a conductive loop, and the main control circuit 61 collects the voltage or current of the conductive loop to obtain a high-level first liquid level detection signal. When the sewage in the sewage tank 31 does not reach one end of the probe assembly 331, the connector pole piece 332 and the main control circuit 61 cannot form a conductive loop, and the main control circuit 61 collects the voltage or current of the conductive loop to obtain a low-level first liquid level detection signal.
The probe assembly 331 comprises a first probe and a second probe, the joint pole piece comprises a first pole piece and a second pole piece, the first probe and the second probe are oppositely arranged in the sewage tank 31, one end of the first probe and one end of the second probe extend into the sewage tank 31, the other end of the first probe is electrically connected with the first pole piece, and the other end of the second probe is electrically connected with the second pole piece. The main control circuit 61 is electrically connected to the first pole piece and the second pole piece, respectively.
When the sewage in the sewage tank 31 reaches one end of the first probe and one end of the second probe, the first pole piece, the main control circuit 61, the second probe and the second pole piece form a conductive loop, and the main control circuit 61 collects the voltage or current of the conductive loop to obtain a high-level first liquid level detection signal. When the sewage in the sewage tank 31 does not reach one end of the probe assembly 331, the first probe, the first pole piece, the main control circuit 61, the second probe and the second pole piece cannot form a conductive loop, and the main control circuit 61 collects the voltage or current of the conductive loop to obtain a first liquid level detection signal with a low level.
The main control circuit 61 generates a shutdown command when detecting that the liquid level of the sewage tank 31 is greater than or equal to a first preset height threshold according to the first liquid level detection signal. In some embodiments, when the first level detection signal is at a high level, the master control circuit 61 detects that the level of the tank 31 is greater than or equal to the first preset level threshold according to the first level detection signal. In some embodiments, when the first level detection signal is at a low level, the master control circuit 61 detects that the level of the tank 31 is less than the first preset level threshold according to the first level detection signal.
In this embodiment, when the sewage tank 31 is full of sewage, in order to avoid pollution to the ground caused by overflow of sewage, a shutdown command can be automatically generated, and the clean water supply assembly 400 is controlled to stop working, the garbage collection assembly 300 is controlled to stop working after a first preset time period is delayed, and the rolling brush assembly 500 is controlled to stop working after a second preset time period is delayed, so that residual sewage can still be prevented from flowing out to the external environment and staying in the external environment under the condition of proximity warning.
In some embodiments, referring still to fig. 7, the garbage collection assembly 300 further includes an in-situ detection assembly 34, where the in-situ detection assembly 34 is disposed on the sewage tank 31 and electrically connected to the master circuit 61 for generating an in-situ detection signal. The main control circuit 61 generates a shutdown command when detecting that the sewage tank 31 is away from a preset position of the housing 200 according to the in-place detection signal.
When the cleaning apparatus 100 is taken away by a user during use, if clean water is continuously supplied and sewage is continuously recovered, the recovered sewage is easy to fall into the cleaning apparatus 100, so that the cleaning apparatus 100 is polluted, however, the present embodiment can detect whether the sewage tank 31 is on the cleaning apparatus 100 or not by the in-situ detection component 34, when the sewage tank 31 is not on the cleaning apparatus 100, the present embodiment can still control the clean water supply component 400 to stop working under the abnormal working state of the cleaning apparatus 100, control the garbage collection component 300 to stop working after the first preset time period is delayed, and control the rolling brush component 500 to stop working after the second preset time period is delayed, so that the residual sewage can be prevented from flowing out to the external environment and staying in the external environment.
The in-situ detection component 34 may be an infrared transceiver, a magnetic element, a hall sensor, or the like.
In some embodiments, referring to fig. 10, the fresh water supply assembly 400 includes a fresh water tank 41 and a water supply assembly 42.
A clean water tank 41 is provided in the housing 200 for storing clean water. The clear water tank 41 may be formed in any shape, such as a square, a rectangular parallelepiped, a cylinder, or the like.
The water supply assembly 42 comprises a water pipe 421, a water pump 422 and a nozzle 423, one end of the water pipe 421 is communicated with the clean water tank 41, the other end of the water pipe 421 is communicated with the nozzle 423, the water pump 422 is arranged on the water pipe 421 and is electrically connected with the main control circuit 61, and the nozzle 423 is arranged on the shell 200 adjacent to the rolling brush assembly 500.
When the cleaning apparatus 100 works normally, the main control circuit 61 controls the water pump 422 to work, the water pump 422 pumps the clean water of the clean water tank 41 through the water pipe 421 and outputs the clean water to the nozzle 423, the nozzle 423 sprays the clean water to the rolling brush assembly 500, and the rolling brush assembly 500 can clean the ground effectively and deeply under the action of the clean water.
When the main control circuit 61 receives the shutdown command, the main control circuit 61 controls the water pump 422 to stop working according to the shutdown command, so that the water pump 422 stops transmitting clean water to the nozzle 423. Because no increment of clear water is output to the rolling brush assembly 500 and sprayed to the ground, the rolling brush assembly 500 can continuously collect residual sewage based on the second preset time period, and the sewage contacted with the ground by the rolling brush assembly 500 can be scraped away, so that secondary pollution is avoided.
In some embodiments, referring to fig. 11, the fresh water supply assembly 400 further includes a second liquid level detection assembly 43, where the second liquid level detection assembly 43 is disposed on the fresh water tank 41 and electrically connected to the main control circuit 61 for generating a second liquid level detection signal. As shown in fig. 10, the second fluid level detection assembly 43 is disposed on the chassis 202 of the clean water tank 41.
In some embodiments, the second level detection assembly 43 generates a high level second level detection signal when the level of fresh water in the fresh water tank 41 is greater than or equal to a second preset level threshold. When the level of the sewage of the clean water tank 41 is less than the second preset level threshold, the second level detection assembly 43 generates a low level second level detection signal.
The point differing from the above-described embodiment is that the second level detection assembly 43 generates a low-level second level detection signal when the level of the fresh water tank 41 is greater than or equal to a second preset level threshold. When the level of the fresh water in the fresh water tank 41 is less than the second preset level threshold, the second level detection assembly 43 generates a high level second level detection signal.
In some embodiments, the second liquid level detection assembly 43 is disposed at the bottom of the clean water tank 41, wherein the second liquid level detection assembly 43 is capable of detecting whether the clean water tank 41 stores clean water, and the liquid level of the clean water is 0 when the clean water tank 41 does not store clean water. When the clean water tank 41 stores clean water, the level of the clean water is greater than 0.
The second level detection assembly 43 may detect the level of the fresh water in the fresh water tank 41 using an infrared light detection technique or a capacitance detection technique.
The main control circuit 61 generates a shutdown command when detecting that the liquid level of the clean water tank is smaller than a second preset height threshold according to the second liquid level detection signal. In some embodiments, when the second level detection signal is at a high level, the master control circuit 61 detects that the level of the clean water tank 41 is greater than or equal to a second preset level threshold based on the second level detection signal. In some embodiments, when the second level detection signal is at a low level, the master control circuit 61 detects that the level of the clean water tank 41 is less than a second preset level threshold according to the second level detection signal.
When the clean water tank 41 enters the water shortage state, the cleaning apparatus 100 enters an abnormal operation state. In this embodiment, when the cleaning apparatus 100 enters an abnormal working state, a shutdown command can be automatically generated, and the clean water supply assembly 400 is controlled to stop working, the garbage collection assembly 300 is controlled to stop working after a first preset time period is delayed, and the rolling brush assembly 500 is controlled to stop working after a second preset time period is delayed, so that the clean water supply assembly 400 can be prevented from working inefficiently, and residual sewage can be prevented from flowing out to the external environment and staying in the external environment.
In some embodiments, referring to fig. 12, a roller brush assembly 500 includes a roller brush 51 and a roller brush motor 52. The rolling brush 51 is disposed at the bottom of the housing 200, the rolling brush motor 52 is disposed at the bottom of the housing 200 and rotatably connected to the rolling brush 51, and the rolling brush motor 52 is further electrically connected to the main control circuit 61.
When the cleaning apparatus 100 is operating normally, the main control circuit 61 transmits a start signal to the blower 321, the water pump 422, and the brush motor 52. The blower 321 starts to operate to discharge air inside the sewage tank 31 to the outside environment, and the sewage tank 31 is set in a negative pressure state, thereby collecting dust, garbage, and sewage on the ground into the sewage tank 31. The water pump 422 pumps out the clean water of the clean water tank 41 through the water pipe 421 and outputs the clean water to the nozzle 423, and the nozzle 423 sprays the clean water to the roller brush 51. The rolling brush motor 52 drives the rolling brush 51 to rotate, and the rolling brush 51 can deeply clean the ground under the action of clean water.
When the main control circuit 61 receives the shutdown command, the main control circuit 61 delays for a second preset time period and then controls the rolling brush motor 52 to stop working, and the rolling brush 51 can scrape away the sewage contacted with the ground by the rolling brush 51 within the second preset time period, so that secondary pollution is avoided.
In some embodiments, the rolling brush assembly 500 further includes a current sampling circuit 53, where the current sampling circuit 53 is electrically connected to the rolling brush motor 52 and the main control circuit 61, respectively, and is configured to sample an operating current of the rolling brush motor 52, and when the main control circuit 61 detects that the operating current is greater than a preset current threshold, a shutdown command is generated. The preset current threshold may be customized by a designer according to engineering experience, for example, the preset current threshold is 6A.
When the cleaning apparatus 100 encounters a large dust catching the brush 51 during use, the operating current of the brush motor 52 may become large. When the working current of the roller brush motor 52 is greater than the preset current threshold, the roller brush motor 52 is easy to burn or a line problem occurs, so that the main control circuit 61 generates a shutdown command when the working current is greater than the preset current threshold, and controls the clean water supply assembly 400 to stop working, controls the garbage collection assembly 300 to stop working after delaying for a first preset time period, and controls the roller brush assembly 500 to stop working after delaying for a second preset time period, so that the residual sewage can be prevented from flowing out to the external environment and staying in the external environment when the cleaning device 100 is in an abnormal state.
In some embodiments, the cleaning apparatus 100 further includes a dirt detection assembly 800, where the dirt detection assembly 800 is disposed on the housing 200 and electrically connected to the main control circuit 61, for detecting a dirt level of the roller brush 51 to obtain a dirt level value. The main control circuit 61 adjusts the first preset time period and/or the second preset time period according to the contamination level value.
When the master control circuit 61 receives the shutdown command, the master control circuit 61 obtains a pollution level set, wherein the pollution level set comprises a plurality of pollution level values arranged in time sequence, and the first preset duration and/or the second preset duration are adjusted according to the pollution level set.
In some embodiments, the main control circuit 61 selects a specified number of the pollution level values with the latest time as the target pollution level values in the pollution level set according to the sequence from the late time to the early time, calculates the difference value of every two adjacent target pollution level values, and adjusts the first preset duration and/or the second preset duration according to the plurality of difference values.
For example, the dirt detecting component 800 detects the dirt level of the roller brush 51 to obtain a dirt level set, where the dirt level set is f= [ p ] 1 ,p 2 ,p 3 ,p 4 ,p 5 ,p 6 ,p 7 ,p 8 ,p 9 ,p 10 ]The dirt degree values of the dirt degree set are arranged according to time sequence.
If the specified number is 6, the master circuit 61 selects a contamination level value p from the set of contamination levels 10 Soil level value p 9 Soil level value p 8 Soil level value p 7 Soil level value p 6 Soil level value p 5 Is the target dirt level value. The main control circuit 61 calculates a difference value between each adjacent two target contamination level values as follows:
Δp 1 ＝p 6 -p 5
Δp 2 ＝p 7 -p 6
Δp 3 ＝p 8 -p 7
Δp 4 ＝p 9 -p 8
Δp 5 ＝p 10 -p 9
the master control circuit 61 then generates a difference Δp 1 Difference delta p 2 Difference delta p 3 Difference delta p 4 Difference Δp 5 And adjusting the first preset time length and/or the second preset time length.
In some embodiments, the main control circuit 61 determines whether the variation trend of the plurality of differences is a monotonically increasing trend according to the order from late to early, if the variation trend is a monotonically increasing trend, the first preset duration and/or the second preset duration are increased, and if the variation trend is a monotonically decreasing trend or a fluctuating variation trend, the first preset duration and/or the second preset duration are adjusted according to the target pollution level value and the preset pollution level.
When the master control circuit 61 increases the first preset duration and/or the second preset duration, the master control circuit 61 increases the first preset difference value on the basis of the first preset duration to obtain an adjusted first preset duration, and/or increases the second preset difference value on the basis of the second preset duration to obtain an adjusted second preset duration, and when the master control circuit 61 receives a shutdown command, the master control circuit 61 delays according to the adjusted first preset duration and then controls the garbage collection assembly 300 to stop working, and delays according to the adjusted second preset duration and then controls the rolling brush assembly 500 to stop working.
When the change trend of the difference values is a monotonically increasing trend, the dirt degree of the rolling brush is continuously enlarged, the enlarging speed is higher, and the fact that the ground is dirty and the sewage is dirty is reflected. When the main control circuit 61 receives the shutdown command, in order to prevent the dirty sewage from remaining on the ground or flowing back to the ground, the main control circuit 61 can extend and adjust the first preset time length or the second preset time length on the basis of the original first preset time length or the second preset time length, delay the first preset time length after adjustment, control the garbage collection assembly 300 to stop working, delay the second preset time length after adjustment, and control the rolling brush assembly 500 to stop working, thereby preventing the dirty sewage from remaining on the ground or flowing back to the ground.
When the change trend of the plurality of difference values is a monotonically decreasing trend or a fluctuation change trend, the dirt degree of the rolling brush is continuously enlarged but the enlarging speed is lower, so that the dirt degree of the ground is reflected to be gradually smaller, but when the dirt degree of the rolling brush is a monotonically decreasing trend or a fluctuation change trend under a relatively high dirt degree value, the dirt degree of the ground is still relatively dirty although the dirt degree of the ground is gradually smaller. When the dirt level of the rolling brush is in a monotonically decreasing trend or a fluctuation trend under a relatively low dirt level value, the dirt level of the ground is not only gradually reduced, but also is relatively light. The main control circuit 61 provided in this embodiment adjusts the first preset duration and/or the second preset duration according to the target dirt level value and the preset dirt level, so that whether the first preset duration and/or the second preset duration need to be adjusted can be comprehensively considered, and the reliability of adjustment is improved.
In some embodiments, the master circuit 61 is configured with a plurality of preset contamination level levels, the preset contamination level levels corresponding to a range of contamination level values, wherein the higher the preset contamination level, the greater the range of contamination level values. For example, the preset soil level is 3, namely, a high soil level, a medium soil level and a low soil level, the soil level range of the high soil level is greater than the soil level range of the medium soil level, and the soil level range of the medium soil level is greater than the soil level range of the low soil level.
The main control circuit 61 calculates an average value of the plurality of target soil level values to obtain a soil average value, determines a soil level corresponding to the soil average value as a target soil level, determines whether the target soil level is a low soil level, if the target soil level is a low soil level, reduces the first preset difference value on the basis of the first preset time length to obtain a reduced first preset time length, and/or reduces the second preset difference value on the basis of the second preset time length to obtain a reduced second preset time length, and when the main control circuit 61 receives a shutdown command, delays according to the reduced first preset time length to control the garbage collection assembly 300 to stop working, and delays according to the reduced second preset time length to control the rolling brush assembly 500 to stop working.
If the target dirt level is not the low dirt level, the main control circuit 61 determines whether the target dirt level is the medium dirt level, and if the target dirt level is the medium dirt level, the main control circuit 61 keeps the first preset time period and the second preset time period unchanged. When the main control circuit 61 receives the shutdown command, the garbage collection assembly 300 is controlled to stop working according to the first preset time length, and the rolling brush assembly 500 is controlled to stop working according to the second preset time length.
If the target dirt level is not the middle dirt level, the main control circuit 61 increases the first preset difference value on the basis of the first preset time length to obtain an adjusted first preset time length, and/or increases the second preset difference value on the basis of the second preset time length to obtain an adjusted second preset time length, and when the main control circuit 61 receives a shutdown command, the main control circuit delays according to the adjusted first preset time length and then controls the garbage collection assembly 300 to stop working, and delays according to the adjusted second preset time length and then controls the rolling brush assembly 500 to stop working.
According to the embodiment, the first preset duration and/or the second preset duration can be flexibly adjusted according to the dirt degree, on one hand, under the condition that the sewage is dirty, the first preset duration and/or the second preset duration can be increased, and therefore the dirty sewage can be reliably prevented from remaining on the ground or flowing back to the ground. On the other hand, under the condition that sewage is not dirty or the sewage is close to clear water, the first preset duration and/or the second preset duration can be reduced, the working time of the cleaning equipment after shutdown is shortened, the electric energy consumption is reduced, and the shutdown efficiency is improved.
In some embodiments, the contamination detection assembly 800 includes an ultrasonic transceiver disposed on the housing 200 adjacent to the roller brush 51, the ultrasonic transceiver being electrically connected to the main control circuit 61 for detecting the contamination level of the roller brush 51 to obtain a contamination level value.
In general, the degree of soiling of the roller brush 51 varies, and the intensity of the reflected ultrasonic signals varies. When the degree of dirt of the roller brush 51 is severe, the dust or the agglomerated dust reflects most of the ultrasonic signals back to the ultrasonic transceiver. When the degree of soiling of the roller brush 51 is relatively low, the roller brush 51 will reflect only a few ultrasonic signals back to the ultrasonic transceiver. Accordingly, the main control circuit 61 obtains the dirt level value of the roller brush 51 from the transmitted ultrasonic signal intensity L1 and the received ultrasonic signal intensity L2.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the invention, the steps may be implemented in any order, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
