Taking running on a mobile terminal as an example, Figure 1 is a hardware structure block diagram of a mobile terminal of a drying control method for a cleaning device according to an embodiment of the present invention, such as Figure 1 As shown, the mobile terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.
[0027] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the drying control method of the cleaning equipment in the embodiment of the present invention. The processor 102 executes various functional applications and service chain address pool slicing processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.
[0028] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.
[0029] In this embodiment, a drying control method for a cleaning device running on the above mobile terminal or network architecture is provided. Figure 2 The process of the drying control method of the cleaning device according to the embodiment of the present invention is as follows: Figure 1 ,like Figure 2 As shown, the cleaning device includes a roller brush, and the process includes the following steps:
[0030] Step S202, when the drying device dries the roller brush, detecting the weight change of the roller brush through the pressure sensor;
[0031] Step S204: determining the drying condition of the roller brush based on the weight change of the roller brush.
[0032] Figure 3 is a schematic diagram of the structure of a floor brush assembly according to an embodiment of the present invention. Figure 3 As shown, the floor brush body of the cleaning device includes a roller brush, which can rotate under the drive of a motor (not shown in the figure), and the user can control the roller brush to rotate to clean the surface to be cleaned. After the roller brush cleans the surface to be cleaned, it is attached with dirt, which can be cleaned manually or by using a base station (cooperating with the cleaning device). After the roller brush is cleaned, in order to prevent the roller brush from being stained due to high humidity, the roller brush can be dried.
[0033] When the cleaning device is in drying mode, i.e., in the drying stage, the roller brush is dried by a drying device, which can use cold air drying, hot air drying, or alternating cold and hot air drying. The drying device can be set in a fixed position (such as a base station or a charging device), or it can be directly set on the cleaning device. The drying device can respond to a trigger instruction to start drying the roller brush. The trigger instruction can be generated in the form of a virtual button, a physical button, a sound, a fingerprint, etc., or it can be generated by the system detecting that the roller brush is too wet.
[0034] During the drying process, the drying condition of the roller brush can be detected by a pressure sensor. The pressure sensor can be specifically arranged near the roller brush of the cleaning device. The weight change of the roller brush is detected by the pressure sensor, and the drying condition of the roller brush is determined by the weight variable of the roller brush.
[0035] Step S206, when it is determined based on the drying condition that the roller brush has been dried, the drying device is controlled to stop working;
[0036] Step S208, when it is determined based on the drying condition that the roller brush is not dried, controlling the drying device to continue working.
[0037] After determining the drying status of the roller brush, the operation of the drying device can be adjusted. Specifically, if the drying status is not dried, continue drying. If the drying status is dried, stop drying, thereby avoiding unnecessary waste of electricity resources.
[0038] In the above embodiment, the roller brush has a lot of moisture after cleaning. The change in the weight of the roller brush during the drying process is detected by the pressure sensor, which can be used to judge the drying condition of the roller brush, thereby controlling the opening and closing of the drying device. The problem that the roller brush drying time of the cleaning equipment in the related art is fixed and cannot adapt to different environments is solved. The working mode of the drying device is controlled according to the drying condition of the roller brush, which can avoid the waste of power resources caused by too long drying time, and at the same time avoid the drying time being too short, resulting in insufficient drying of the roller brush, mold and odor, etc.
[0039] In one or more embodiments, the weight change of the roller brush may be determined by the pressure values of the pressure sensor obtained in adjacent time periods. Accordingly, the above step S202 may specifically include:
[0040] S11, obtaining the pressure value of the pressure sensor at every preset time period, determining the pressure change of the roller brush according to the pressure difference between the pressure value of the current time period and the pressure value of the previous time period, and determining the weight change of the roller brush according to the pressure change of the roller brush, that is, the pressure difference of adjacent time periods can be determined based on the pressure value of the pressure sensor, so as to determine the pressure change of the roller brush causing deformation, and then the weight change of the roller brush can be determined based on the pressure change; or,
[0041] S12, obtaining the pressure value of the pressure sensor at every preset time period, determining the weight value of the roller brush in the current time period according to the pressure value of the current time period, and determining the weight change of the roller brush according to the weight value of the roller brush in the current time period and the weight value of the roller brush in the previous time period, that is, first determining the weight value of the roller brush based on the pressure value of the pressure sensor in each time period, and then determining the weight change of the roller brush according to the weight difference of the roller brush in adjacent time periods.
[0042] Correspondingly, in the above step S204, the drying status of the roller brush can be determined according to the weight change of the roller brush in the following way: if the weight change of the roller brush is less than or equal to the first preset weight, the drying status of the roller brush is determined to be dried; if the weight change of the roller brush is greater than the first preset weight, the drying status of the roller brush is determined to be undried.
[0043] The preset time period and the first preset weight in this embodiment can be set according to actual conditions. For example, the preset time period can be set to 2-10 minutes, and the first preset weight can be set to a value between 0-0.5g.
[0044] The following is an example in which the preset time period is set to 3 minutes and the first preset weight is set to 0.3g. At 9:00, the weight value of the roller brush detected by the weight sensor for the first time is X1=220g. At 9:03, the weight value of the roller brush detected by the weight sensor for the second time is X2=215g. The weight difference between the second detection and the first detection is calculated to be X2-X1=-5g. At this time, it is determined whether the absolute value of X2-X1 is less than 0.2g. Since the absolute value of X2-X1, 5g, is greater than 0.2g, the drying condition of the roller brush is not dried, and further detection is required. At 9:06, the weight value of the roller brush detected by the weight sensor for the third time is X3=210g. The weight difference between the third detection and the second detection is calculated to be X3-X2=-5g. At this time, it is determined whether the absolute value of X3-X2 is less than 0.2g. Since the absolute value of X3-X2, 5g, is greater than 0.2g, the drying condition of the roller brush is not dried, and further detection is required. At 9:09, the weight value of the roller brush detected by the weight sensor for the fourth time is X4=206g, and the weight difference between the weight values of the fourth and third tests is calculated to be X4-X3=-4g. At this time, it is judged whether the absolute value of X4-X3 is less than 0.2g. Since the absolute value of X4-X3, 4g, is greater than 0.2g, the drying condition of the roller brush is not dried, and further testing is required. At 9:12, the weight value of the roller brush detected by the weight sensor for the fifth time is X5=202g, and the weight difference between the weight values of the fifth and fourth tests is calculated to be X5-X4=-4g. At this time, it is judged whether the absolute value of X5-X4 is less than 0.2g. Since the absolute value of X5-X4, 4g, is greater than 0.2g, the drying condition of the roller brush is not dried, and further testing is required. 9:15, the weight value of the roller brush detected by the weight sensor for the sixth time is X6=198g, and the weight difference between the weight values of the sixth and fifth tests is calculated to be X6-X5=-4g. At this time, it is judged whether the absolute value of X6-X5 is less than 0.2g. Since the absolute value of X6-X5, 4g, is greater than 0.2g, the drying condition of the roller brush is not dried, and further testing is required. 9:18, the weight value of the roller brush detected by the weight sensor for the seventh time is X7=197.9g, and the weight difference between the weight values of the seventh and sixth tests is calculated to be X7-X6=-0.1g. At this time, it is judged whether the absolute value of X7-X6 is less than 0.2g. Since the absolute value of X7-X6, 0.1g, is less than 0.2g, the drying condition of the roller brush is dried.
[0045] In other embodiments, the weight change of the roller brush may be determined by the pressure value of the pressure sensor obtained during the current time period and the initial time period. Accordingly, the above step S202 may specifically include:
[0046] S21, obtaining the pressure value of the pressure sensor at every preset time period, determining the pressure change of the roller brush according to the pressure difference between the pressure value of the current time period and the initial pressure value, and determining the weight change of the roller brush according to the pressure change of the roller brush, that is, starting from the cleaning device entering the drying mode, the pressure value of the pressure sensor is obtained at a preset time period, and in each time period (called the current time period), the pressure difference with the initial pressure value obtained in the initial time period is determined, thereby determining the pressure change of the roller brush, and then the weight change of the roller brush can be determined; or,
[0047] S22, obtaining the pressure value of the pressure sensor at every preset time period, determining the weight value of the roller brush in the current time period according to the pressure value of the current time period, and determining the weight change of the roller brush according to the weight value of the roller brush in the current time period and the initial weight value, that is, in each time period, first determine the weight value of the roller brush based on the pressure value of the pressure sensor, and then determine the weight change of the roller brush as the weight value of the roller brush in the current time period and the initial weight value obtained in the initial time period.
[0048] Correspondingly, the above step S204 can be specifically determined in the following manner: if the weight change of the roller brush is greater than or equal to the second preset weight, the drying condition of the roller brush is determined to be dried; if the weight change of the roller brush is less than the second preset weight, the drying condition of the roller brush is determined to be undried, and the second preset weight is greater than the first preset weight.
[0049] The preset time period and the second preset weight in this embodiment can be set according to actual conditions. For example, the preset time period can be set to 2-10 minutes, and the second preset weight can be set to a value between 20-25g. As the roller brush is used for a longer time, some wear and tear will occur, so the initial weight value will change. The second preset weight can also be updated after a period of time. The value of the second preset weight can be slightly reduced after a period of time to more accurately determine whether the roller brush has been dried.
[0050] The following is an example in which the preset time period is set to 3 minutes and the second preset weight is set to 22g. At 9:00, the weight value of the roller brush detected by the weight sensor for the first time is X1=220g (i.e., the initial weight value). At 9:03, the weight value of the roller brush detected by the weight sensor for the second time is X2=215g. The weight difference between the second detection and the initial weight value is calculated to be X2-X1=-5g. At this time, it is determined whether the absolute value of X2-X1 is less than 22g. Since the absolute value of X2-X1 is 5g less than 22g, the drying condition of the roller brush is not dried, and further detection is required. At 9:06, the weight value of the roller brush detected by the weight sensor for the third time is X3=210g. The weight difference between the third detection and the initial weight value is calculated to be X3-X1=-10g. At this time, it is determined whether the absolute value of X3-X1 is less than 0.2g. Since the absolute value of X3-X1 is 10g less than 22g, the drying condition of the roller brush is not dried, and further detection is required. 9:09, the weight value of the roller brush detected by the weight sensor for the fourth time is X4=206g, and the weight difference between the fourth detection and the initial weight value is calculated to be X4-X1=-14g. At this time, it is judged whether the absolute value of X4-X1 is less than 22g. Since the absolute value of X4-X1, 14g, is less than 22g, the drying condition of the roller brush is not dried, and further detection is required. 9:12, the weight value of the roller brush detected by the weight sensor for the fifth time is X5=202g, and the weight difference between the fifth detection and the initial weight value is calculated to be X5-X1=-18g. At this time, it is judged whether the absolute value of X5-X1 is less than 22g. Since the absolute value of X5-X1, 18g, is less than 22g, the drying condition of the roller brush is not dried, and further detection is required. 9:15, the weight value of the roller brush detected by the weight sensor for the sixth time is X6=198g, and the weight difference between the sixth detection and the initial weight value is calculated to be X6-X1=-22g. At this time, it is judged whether the absolute value of X6-X1 is less than 22g. Since the absolute value of X6-X1 22g is equal to 22g, the drying condition of the roller brush is dried.
[0051] The embodiment of the present invention detects the weight change of the roller brush through a pressure sensor. The pressure sensor can be arranged on the cantilevers at both ends of the roller brush, and of course can also be arranged at other positions where the weight change of the roller brush can be detected.
[0052] In one embodiment, the pressure sensor is a strain type pressure sensor. The cleaning device in the embodiment of the present invention also includes: a floor brush assembly; a cantilever, the roller brush is rotatably connected to the side of one end of the cantilever, and the other end of the cantilever is connected to the floor brush assembly (the roller brush can rotate on the side of the cantilever), and the strain type pressure sensor is arranged on the cantilever, and the strain type pressure sensor can specifically be a strain gauge.
[0053] Specifically, the weight change of the roller brush when the cleaning device is in the drying mode is detected by strain gauges arranged on the cantilevers at both ends of the roller brush. Specifically, the pressure of the roller brush can be detected by a pressure sensor at a preset time period, and the weight change of the roller brush can be determined by the pressure change and pressure difference detected in adjacent periods. Further, the resistance value of the strain gauge is detected at each preset time period, and the gravity change of the roller brush is determined according to the resistance difference between the resistance value of the current time period and the resistance value of the previous time period, and the weight change of the roller brush is determined according to the gravity change of the roller brush; or the pressure value of the pressure sensor is detected at each preset time period, and the weight change of the roller brush is determined according to the pressure difference between the pressure value of the current time period and the pressure value of the previous time period. That is, the deformation of the cantilevers at both ends of the roller brush is converted into an electrical signal by the strain gauge, and the deformation of the cantilevers at both ends of the roller brush is determined according to the change of the electrical signal, and the weight change of the roller brush can be determined according to the deformation of the cantilevers at both ends of the roller brush.
[0054] The strain gauge in this embodiment can specifically be a resistance strain gauge, which is a sensor that can convert deformation such as force, pressure, weight, etc. into resistance change. Its working principle is based on the strain effect of the resistance material, that is, when subjected to force, the length, width, thickness and other dimensions of the resistance strain gauge will change slightly, resulting in a change in resistance value. By using electronic devices such as bridge circuits and amplifiers, the slight resistance change can be converted into a voltage signal, thereby realizing the measurement and control of deformation. The resistance strain gauge has the characteristics of high precision, high reliability, and high sensitivity. The resistance strain gauge is usually made of metal foil or conductive film, and its shape can be rectangular, circular or other shapes. When the resistance strain gauge is subjected to external force from the roller brush, such as stretching, compression or bending, its shape will change, resulting in a change in resistance value, and the weight change of the roller brush can be determined based on the change in resistance value.
[0055] In another embodiment, the pressure sensor is a piezoresistive pressure sensor, a capacitive pressure sensor or a piezoelectric pressure sensor, and the cleaning equipment in the embodiment of the present invention also includes: a floor brush assembly, a cantilever, a roller brush is rotatably connected to the side of one end of the cantilever, and the other end of the cantilever is connected to the floor brush assembly, and the piezoresistive pressure sensor, capacitive pressure sensor or piezoelectric pressure sensor is arranged on the upper end surface of the cantilever and contacts with the corresponding part of the floor brush assembly; or, the cantilever, the roller brush is rotatably connected to the side of one end of the cantilever (the roller brush can rotate on the side of the cantilever), and the other end of the cantilever is connected to the floor brush assembly, and the piezoresistive pressure sensor, capacitive pressure sensor or piezoelectric pressure sensor is arranged on the lower end surface of the cantilever and contacts with the corresponding part of the floor brush assembly.
[0056] like Figure 3As shown, the floor brush assembly includes a floor brush body and a transparent window, wherein the floor brush body includes an upper shell and a lower shell, the roller brush is rotatably connected to the side of one end of the cantilever, and the other end of the cantilever is connected to the upper shell and the lower shell of the floor brush body.
[0057] Figure 4 is a schematic diagram of a structure of a pressure sensor according to an embodiment of the present invention. Figure 4 As shown, the piezoresistive pressure sensor, capacitive pressure sensor or piezoelectric pressure sensor is connected to the upper shell and the lower shell of the floor brush body. The strain gauge only needs to be set on the cantilever and may not be in contact with the upper shell and the lower shell, but of course it can also be in contact with the upper shell and the lower shell.
[0058] In this embodiment, a drying control method for a cleaning device is also provided. Figure 5 The process of the drying control method of the cleaning device according to the embodiment of the present invention is as follows: Figure 2 ,like Figure 5 As shown, the cleaning device includes a roller brush, and the process includes the following steps:
[0059] Step S502, when the drying device dries the roller brush, the weight change of the roller brush is detected by the pressure sensor at every preset time period, and the weight change of the roller brush is the weight difference detected in adjacent time periods;
[0060] Step S504, determining the drying status of the roller brush based on the weight change of the roller brush;
[0061] Step S506, when it is determined based on the drying condition that the roller brush has been dried, controlling the drying device to stop working;
[0062] Step S508, when it is determined based on the drying condition that the roller brush is not dried, controlling the drying device to continue working.
[0063] In the embodiment of the present invention, the weight change of the roller brush is determined by the pressure value of the pressure sensor obtained in adjacent time periods. In the above step S502, the weight change of the roller brush is detected by the pressure sensor every preset time period, which may specifically include:
[0064] S11, obtaining the pressure value of the pressure sensor at every preset time period, determining the pressure change of the roller brush according to the pressure difference between the pressure value of the current time period and the pressure value of the previous time period, and determining the weight change of the roller brush according to the pressure change of the roller brush, that is, the pressure difference of adjacent time periods can be determined based on the pressure value of the pressure sensor, so as to determine the pressure change of the roller brush causing deformation, and then the weight change of the roller brush can be determined based on the pressure change; or,
[0065] S12, obtaining the pressure value of the pressure sensor at every preset time period, determining the weight value of the roller brush in the current time period according to the pressure value of the current time period, and determining the weight change of the roller brush according to the weight value of the roller brush in the current time period and the weight value of the previous time period, that is, first determining the weight value of the roller brush based on the pressure value of the pressure sensor in each time period, and then determining the weight change of the roller brush according to the weight difference of the roller brush in adjacent time periods.
[0066] Correspondingly, in the above step S504, the drying status of the roller brush according to the weight change of the roller brush can be determined in the following way: if the weight change of the roller brush is less than or equal to the first preset weight, the drying status of the roller brush is determined to be dried; if the weight change of the roller brush is greater than the first preset weight, the drying status of the roller brush is determined to be undried. The preset time period and the first preset weight in this embodiment can be set according to actual conditions. For example, the preset time period can be set to 2-10 minutes, and the first preset weight can be set to a value between 0-0.5g. No more examples are given here.
[0067] The embodiment of the present invention detects the weight change of the roller brush through a pressure sensor. The pressure sensor can be arranged on the cantilevers at both ends of the roller brush, and of course can also be arranged at other positions where the weight change of the roller brush can be detected.
[0068] In some embodiments, the pressure sensor is a strain type pressure sensor, and the cleaning equipment also includes: a floor brush assembly, a cantilever, a roller brush rotatably connected to the side of one end of the cantilever, the other end of the cantilever is connected to the floor brush assembly, and the strain type pressure sensor is arranged on the cantilever.
[0069] In other embodiments, the pressure sensor is a piezoresistive pressure sensor, a capacitive pressure sensor or a piezoelectric pressure sensor, and the cleaning device also includes: a floor brush assembly, a cantilever, a roller brush rotatably connected to the side of one end of the cantilever, the other end of the cantilever is connected to the floor brush assembly, and the piezoresistive pressure sensor, capacitive pressure sensor or piezoelectric pressure sensor is arranged on the upper end surface of the cantilever and contacts with the corresponding part of the floor brush assembly; or, the cleaning device also includes: a floor brush assembly, a cantilever, a roller brush rotatably connected to the side of one end of the cantilever, the other end of the cantilever is connected to the floor brush assembly, and the piezoresistive pressure sensor, capacitive pressure sensor or piezoelectric pressure sensor is arranged on the lower end surface of the cantilever and contacts with the corresponding part of the floor brush assembly.
[0070] The cleaning device in this embodiment can be a handheld floor scrubber or a handheld sweeper. Figure 6 is a schematic diagram of the structure of a handheld floor scrubber according to an embodiment of the present invention. Figure 6As shown, the body 1 of the handheld floor scrubber includes a floor brush assembly 13, a long handle 15, a cleaning accessory 14 and a roller 16. The roller 16 is arranged on the side of the floor brush assembly 13 facing the user, and the roller 16 can assist the floor brush assembly 13 to move on the ground; the roller brush 2 is arranged on the side of the floor brush assembly 13 away from the user, that is, the roller brush 2 is arranged on the rear side of the floor brush assembly 13, and the roller 16 is arranged on the front side of the floor brush assembly 13.
[0071] Furthermore, the roller brush 2 is rotatably connected to the floor brush assembly 13, and the long handle 15 is connected to the floor brush assembly 13. The long handle 15 is provided with cleaning accessories 14, such as batteries, dust boxes, sewage tanks and other components well known to those skilled in the art, depending on the specific structure and function of the cleaning equipment, and this application does not limit it here. In actual use, the user holds the handle 15, places the floor brush assembly 13 on the ground to be cleaned, makes the roller brush 2 contact with the ground, and assists the floor brush assembly 13 to walk on the ground through the roller 16 to perform the cleaning operation.
[0072] If the drying device is arranged inside the cleaning device, the roller brush can rotate relative to the body of the cleaning device to clean the floor to be cleaned. The roller brush has a receiving cavity and a driving assembly, one end of which is connected to the body, and the other end extends into the receiving cavity and cooperates with the roller brush transmission. The driving assembly includes a motor. When the floor needs to be cleaned, the driving assembly drives the roller brush to rotate through the motor; when drying is required (i.e., in drying mode), the roller brush remains stationary, and the motor generates heat as a heat source and dries the roller brush. The drying device is integrated into the floor brush housing, so there is no need to change the structure of the base, and there is no need to make major changes to the overall shape of the cleaning device, which greatly saves the cost of design, development and manufacturing.
[0073] The drying device can also be arranged outside the cleaning device, that is, the drying device and the cleaning device are arranged independently. Figure 7 is a schematic diagram of the structure of a drying device according to an embodiment of the present invention, such as Figure 7 As shown, the drying device includes a base 3 and an air-drying component 5. A cavity is provided in the base 3, and the air-drying component 5 is installed in the cavity. The base 3 is also provided with at least one air outlet 4 connected to the cavity fluid to form a gas flow channel with the cavity. When the roller brush needs to be dried, the roller brush is placed directly above the air outlet 4, and the air blown out from the air outlet 4 dries the roller brush.
[0074] In this embodiment, the drying condition of the roller brush can also be detected by a humidity sensor. The humidity sensor can be set on the roller brush or in a position that can contact the roller brush. Specifically, the humidity change of the roller brush when the cleaning device is in the drying mode is detected by the humidity sensor set on the roller brush or in contact with the roller brush. Further, the humidity value of the humidity sensor is detected at each preset time period; the humidity change of the roller brush is determined according to the humidity difference between the humidity value of the current time period and the humidity value of the previous time period; the drying condition of the roller brush is determined according to the humidity change of the roller brush. Specifically, if the humidity change of the roller brush is less than or equal to the preset humidity, the drying condition of the roller brush is determined to be dried; if the humidity change of the roller brush is greater than the preset humidity, the drying condition of the roller brush is determined to be not dried. The preset humidity in this embodiment can be set according to actual conditions.
[0075] The preset time period and preset humidity in this embodiment can be set according to actual conditions. For example, the preset time period can be set to 3-10 minutes, and the preset humidity can be set to a value between 40% and 80%.
[0076] In an embodiment of the present invention, when the drying condition of the roller brush is dried, the drying time of the cleaning device is set to 0 to stop drying the cleaning device; when the drying condition of the roller brush is undried, the drying time of the cleaning device is set to a preset drying time, and the drying condition of the roller brush continues to be detected at a preset time period during the drying process, and the drying time continues to be adjusted according to the drying condition of the roller brush. If the conditions for stopping drying are not met within the preset drying time, the drying is stopped after the preset drying time is reached, wherein the preset drying time is greater than the above-mentioned preset time period.
[0077] The preset drying time in this embodiment can be set according to actual conditions, for example, it can be set to 20-50 minutes, and the specific value is not limited here.
[0078] If the preset drying time is set to 22 minutes, for the above example, after the first time, since the drying condition of the roller brush is not dried, the preset drying time will be continued, that is, the drying will be continued for a maximum of 22 minutes. The results of the second to sixth tests are all not dried, then the drying will be continued for 22 minutes from the first test. When the drying condition of the roller brush is tested for the seventh time, the drying condition of the roller brush is dried, that is, the roller brush has been dried within the longest preset drying time, then the drying will be stopped.
[0079] If the preset drying time is set to 18 minutes, for the above example, after the first time, since the drying condition of the roller brush is not dried, the preset drying time will be continued, that is, drying will be continued for a maximum of 18 minutes. The results of the second to fifth tests are all not dried, then drying will be continued within 20 minutes from the first test. However, after drying for 18 minutes, the drying condition of the roller brush is tested for the sixth time. At this time, the drying condition of the roller brush is still not dried. Since the longest preset drying time has been reached, drying is stopped.
[0080] During the roller brush drying stage (i.e. in drying mode), the drying condition of the roller brush is detected and accurately judged, and the drying time of the roller brush is intelligently adjusted based on the detection signal to avoid wasting electricity resources due to too long drying time, while also avoiding too short drying time resulting in insufficient drying of the roller brush, mold and odor, etc.
[0081] Figure 8 is a schematic diagram of a cleaning device according to this embodiment Figure 1 , Fig. 9 is a schematic diagram of a cleaning device according to this embodiment Figure 2 ,like Figure 8 , Fig. 9 As shown in the figure, the cleaning equipment for intelligent drying has strain gauges attached to the upper and lower cantilevers at both ends of the roller brush. Two strain gauges are set on the upper and lower cantilevers of one side. Through the half-bridge circuit, the pressure and the electrical signal can be linearly related, and the linear error is zero. However, if one strain gauge is set, there is a linear error, and the error will increase with the increase of pressure. Two strain gauges are set on the upper and lower sides, that is, four strain gauges are set, and the sensitivity is higher, which is twice the sensitivity of setting two strain gauges. Without considering the cost, setting four strain gauges is the best solution. If two strain gauges meet the sensitivity requirements, it is more cost-effective. During the drying process of the roller brush, the moisture on the roller brush continues to evaporate, the weight of the roller brush continues to decrease, the force on the roller brush cantilever continues to decrease, the deformation of the roller brush cantilever shrinks, and the deformation change is converted into an electrical signal (strain gauge resistance change) through the strain gauge. The controller calculates the change in the force on the cantilever according to the change in the electrical signal, thereby obtaining the change in the weight of the roller brush. This solution can detect the drying state of the roller brush in real time and accurately and timely determine whether the roller brush has been dried. If it has been dried, stop the fan and heating wire in time to save energy and protect the environment and avoid electricity waste; if it has not been dried, continue the drying process.
[0082] Fig.10 is a flow chart of the drying control of the cleaning device according to this embodiment. Fig.10 As shown, including:
[0083] S1001, start drying mode;
[0084] S1002, detecting the weight G1 of the roller brush;
[0085] S1003, a period of time T0;
[0086] S1004, detecting the weight G2 of the roller brush;
[0087] S1005, M = G1-G2;
[0088] S1006, assign G1=G2;
[0089] S1007, determine whether M is greater than a preset value M0, if the determination result is yes, return to S1003, if the determination result is no, execute S1008;
[0090] S1008, the roller brush has been dried, and the drying mode ends.
[0091] When entering the drying mode, the roller brush weight G1 is obtained by detecting the electrical signal of the strain gauge. After an interval of time T0, the roller brush weight G2 is continuously detected, and the difference M between G1 and G2 is calculated, and then the value of G2 is assigned to G1. If M≤M0, it means that the roller brush has reached the drying state and the drying mode ends; when M is greater than the preset value M0, it means that the roller brush has not been dried and the drying work needs to continue. The roller brush weight is detected once every time T0, and then the difference M between the previous value G1 and the current detected value G2 is continuously calculated. By comparing M with the preset value M0, it is determined whether the roller brush has been dried. The range of M0 is 0.1g-5g, and the preferred value is 1.5g. The range of T0 is 0-10min, preferably 0-2min. By the size of the change in the roller brush weight over a certain period of time, it is accurately determined whether the roller brush has been dried.
[0092] Fig.11 This is a schematic diagram of the roller brush gravity acting on the cantilever according to this embodiment. Figure 1 , Fig.12 This is a schematic diagram of the roller brush gravity acting on the cantilever according to this embodiment. Figure 2 ,like Fig.11 , Fig.12 As shown, the gravity of the roller brush acts on the cantilever, and the entire cantilever will be deformed, the upper surface will be elongated, and the lower surface will be shortened. The strain gauge is attached to the upper or lower surface, and will produce corresponding deformation along with the cantilever, so that the resistance value in the strain gauge will change. Therefore, the gravity of the roller brush acting on the cantilever can be obtained according to the change in the resistance value of the strain gauge in the circuit. During the drying process, the change in the gravity of the roller brush can be used to determine whether the roller brush has been dried. For easy understanding, Figure 11-12 The deformation in the middle is large, but the actual deformation is relatively small and difficult to observe with the naked eye.
[0093] The strain gauge in this embodiment is not limited to be installed on the cantilever, that is, the installation position is not limited. As long as the position where the weight change of the roller brush can be detected, it is within the protection scope of this embodiment. At the same time, the number of strain gauges is not limited. Figure 8 , Fig. 9 The installation position and number of the strain gauges are only used as an example for convenience of explanation. The strain gauge is only used as a sensor that can detect the weight change of the roller brush. The detection sensor can be a strain gauge, a pressure sensor, etc.
[0094] In this embodiment, a strain gauge or a pressure sensor is used to detect the weight change of the roller brush, so as to determine whether the roller brush has been dried. A humidity sensor can also be used to detect the humidity or water content of the roller brush, so as to control the drying time of the roller brush. Fig.13 is a schematic diagram of detecting the humidity of the roller brush according to this embodiment, such as Fig.13 As shown, a humidity sensor is provided on the roller brush to detect the humidity change of the roller brush, and the drying time of the roller brush is controlled according to the humidity change of the roller brush.
[0095] This embodiment can accurately detect the drying condition of the roller brush and determine whether the roller brush has reached the drying state, so that the drying module can adapt to various environments. It can avoid power waste caused by too long drying, which is more environmentally friendly and energy-saving. At the same time, it can avoid too short drying that causes the roller brush to mold and breed bacteria, thereby improving the user experience and ensuring the health and safety of the user.
