Illustratively, in some embodiments, the dust collection device may be used in a base station to recover dirt from a dust box of a sweeper, scrubber or mopping machine.

As shown in fig. 1, 3 and 4, the dust collecting device may include a main body structure 100, a wind wheel assembly 200, a dust bag 300, a blower 400, and an induction member 500.

Wherein the main body structure 100 may serve as a mounting carrier in a dust collecting device. In an embodiment, the body structure 100 may comprise a first receiving cavity 101.

The wind wheel assembly 200 may be installed in the first accommodating cavity 101, and may divide the first accommodating cavity 101 into a first sub-chamber 1011 and a second sub-chamber 1012 which are isolated from each other. In some embodiments, the wind turbine assembly 200 may include a second housing cavity 201 and a wind turbine 220 located in the second housing cavity 201. It will be appreciated that wind wheel 220 is rotatably mounted in second housing cavity 201. In addition, the second receiving chamber 201 may communicate with the first sub-chamber 1011.

The dust bag 300 may be disposed in the first sub-chamber 1011. In an embodiment, the dust bag 300 may be removably mounted with respect to the main body structure 100 for user replacement of the dust bag 300. In addition, the dust bag 300 may include an input port 310, a dust collection chamber 320, and an air outlet (not shown) that are sequentially connected. Wherein, the air outlet may be formed in a mesh (not shown) on the dust bag 300, and the air outlet may be in communication with the first sub-chamber 1011.

The blower 400 may be installed in the main body structure 100, and an air inlet of the blower 400 may be in communication with the first sub-chamber 1011. In an embodiment, the fan 400 may be used as a power source in the dust collecting device, and may be used to drive airflow to flow, so that the dust collecting device may perform dust collection.

The sensing element 500 may be mounted in the second subchamber 1012. The sensing member 500 may be used to detect the rotational speed of the wind wheel 220.

In operation, the blower 400 may drive airflow, and external airflow may enter the dust collection cavity 320 through the input port 310 of the dust bag 300 and enter the first sub-chamber 1011 through the air outlet. In this process, dirt may enter the dust collection chamber 320 by the air flow and remain in the dust collection chamber 320. After the air flow enters the first sub-chamber 1011, the air flow may enter the second accommodating cavity 201 of the wind wheel assembly 200 and drive the wind wheel 220 to rotate. In addition, the air flow in the first sub-chamber 1011 may be discharged through the blower 400.

It will be appreciated that as the amount of dust collected in the dust bag 300 increases, the resistance to airflow increases, which in turn reduces the airflow rate. When the flow speed of the air flow is gradually reduced, the rotation speed of the wind wheel 220 is also reduced, so that the dust collection amount in the dust bag 300 can be reflected by the rotation speed of the wind wheel 220. In an embodiment, the sensing element 500 can detect the rotation speed of the wind wheel 220, so as to detect the dust collection amount in the dust bag 300. In an embodiment, the airflow flowing through the wind wheel 220 can be consistent with that in the dust bag 300, so that the detection result can be more accurate and reliable.

In an embodiment, the wind wheel 220 is driven to rotate by flowing airflow, and no power is needed. It is appreciated that in the present application, the exposed structure of the wind wheel assembly 200 relative to the airflow is not electrified, so that the problem of erosion short circuit caused by dirt, water vapor, etc. carried in the airflow is avoided.

In addition, the sensor 500 is disposed in the second sub-chamber 1012, and the second sub-chamber 1012 is isolated from the first sub-chamber 1011. Therefore, the induction piece 500 can be isolated from the air flow, so that the problems of short circuit and the like caused by corrosion of dirt, water vapor and the like carried in the air flow to the induction piece 500 can be prevented, the induction piece 500 can be protected, the working stability of the induction piece 500 is ensured, and the service life of the induction piece 500 is prolonged.

As shown in fig. 1 and 3, further, in some embodiments, the body structure 100 may include a main housing 110 and a shell 120. The first accommodating cavity 101 may be formed in the main housing 110, and one end of the first accommodating cavity 101 is of an opening structure, and the opening structure is communicated with the first sub-chamber 1011. The cover 120 is detachably connected to the opening structure of the first accommodating cavity 101, and can close the opening structure of the first accommodating cavity 101. When the user needs to replace the dust bag 300, the cover 120 can be detached from the main housing 110, so that the opening structure of the first accommodating chamber 101 is opened, and the user can take out the dust bag 300 from the first accommodating chamber 101 for replacement.

Illustratively, in some embodiments, the cover 120 may be removably coupled to the main housing 110 by a snap-fit connection, a tight fit, or the like.

In addition, a third accommodating cavity 102 is formed at one end of the main housing 110 away from the cover 120. The third accommodating chamber 102 and the first accommodating chamber 101 may be partitioned by a partition 111. In an embodiment, the fan 400 may be fixedly installed in the third accommodating cavity 102, and may be in communication with the first accommodating cavity 101 through the first through hole 112 on the partition 111. Specifically, the air inlet of the blower 400 may be in communication with the first sub-chamber 1011 through the first through hole 112.

As shown in fig. 4 to 6, the wind wheel assembly 200 further includes a first housing 211 and a second housing 212. The first housing 211 and the second housing 212 may be coupled to define the second accommodating chamber 201. In an embodiment, the first housing 211 is detachably connected to the second housing 212. Therefore, the second accommodating cavity 201 can be conveniently opened by a user, so that maintenance or replacement and other operations can be provided for the wind wheel 220 and other structures in the second accommodating cavity 201.

Illustratively, the first housing 211 and the second housing 212 may be detachably connected by a threaded connection. Specifically, an end of the first housing 211 near the second housing 212 may be provided with an internal thread 2112. The end of the second housing 212 adjacent to the first housing 211 may be provided with external threads 2121 that mate with the internal threads 2112. Accordingly, the first housing 211 and the second housing 212 may be detachably coupled by the female screw 2112 and the male screw 2121.

In other embodiments, the first housing 211 and the second housing 212 may be detachably connected by a snap connection or a tight fit.

In some embodiments, the side of the first housing 211 away from the second housing 212 is further provided with a protruding portion 2113, which can provide a force location for a user, and facilitate the user to screw the first housing 211 to disassemble the first housing 211 and the second housing 212. In addition, the lateral surface of the hand-holding portion 2113 may be provided with anti-slip patterns, which may prevent the user from slipping during screwing the first housing 211, and further facilitate the user to screw the first housing 211.

In some embodiments, the partition 111 may sink away from the first sub-chamber 1011 and form a sink 113. In an embodiment, the second housing 212 may be fixedly disposed in the sink 113, and the second housing 212 and the bottom of the sink 113 are combined to form a second sub-chamber 1012. Illustratively, the second housing 212 may be fixedly mounted in the sink 113 by means of an adhesive, a snap fit, or an interference fit. In an embodiment, the sensing element 500 may be fixedly installed between the second housing 212 and the bottom of the sink 113.

It will be appreciated that the end of the second housing 212 provided with the external screw 2121 may protrude with respect to the sink 113 so as to be detachably coupled with the first housing 211.

In some embodiments, the first housing 211 may be provided with a communication hole 2111. The communication hole 2111 may communicate with the first sub-chamber 1011 and the second accommodation chamber 201, respectively. Thus, communication between the first sub-chamber 1011 and the second accommodation chamber 201 can be achieved.

In some embodiments, wind turbine assembly 200 also includes a filter mesh 250. The filter 250 may be fixedly installed on one side of the first housing 211 near the second accommodation chamber 201, and covers the communication hole 2111. In an embodiment, the filter screen 250 can filter the airflow flowing through the communication hole 2111, so as to reduce the dirt entering the second accommodating cavity 201, further avoid the dirt interfering with the rotation of the wind wheel 220, reduce the occurrence of abnormal noise or jamming and other problems, and simultaneously reduce the possibility of damage to the wind wheel 220 and other structures in the second accommodating cavity 201, and prolong the service life of the wind wheel assembly 200.

In some embodiments, the filter 250 may be fixedly mounted on a side of the first housing 211 adjacent to the second accommodating cavity 201 by means of beer sleeving, bonding or structure limiting. In an embodiment, filter screen 250 may include, but is not limited to, at least one of a steel mesh or a nylon mesh.

In some embodiments, wind turbine assembly 200 also includes a connection shaft 230. The wind wheel 220 is rotatably mounted in the second accommodating chamber 201 through a connecting shaft 230. Specifically, the connection shaft 230 is rotatably installed between the first housing 211 and the second housing 212. The wind wheel 220 may be fixedly mounted on the connection shaft 230. When the wind wheel 220 rotates under the action of the airflow, the connection shaft 230 can be driven to rotate synchronously. In addition, the connection shaft 230 is detachably connected to the first housing 211 and the second housing 212, respectively. When the wind wheel 220 and other structures have problems and need to be replaced, the wind wheel 220 and other structures can be conveniently detached from the first shell 211 and the second shell 212 by a user, and the whole wind wheel assembly 200 does not need to be replaced, so that the later maintenance cost of the dust collecting device can be reduced.

In some embodiments, sensing element 500 may be a hall sensor. The wind turbine assembly 200 also includes a magnetic member 240. The magnetic member 240 may be fixedly disposed with respect to the wind wheel 220. That is, when the wind wheel 220 rotates under the driving of the airflow, the magnetic member 240 can synchronously rotate along with the wind wheel 220.

In some embodiments, magnetic member 240 may be a magnetic ring. The magnetic member 240 may be fixedly sleeved on the circumference of the connection shaft 230. When the wind wheel 220 drives the connecting shaft 230 to rotate, the magnetic member 240 can be driven to rotate synchronously. It will be appreciated that the magnetic field generated by the magnetic member 240 will also change in real time during rotation of the magnetic member 240. The sensing element 500 can detect the rotation speed of the magnetic element 240 according to the change of the magnetic field generated by the magnetic element 240, so as to obtain the rotation speed of the wind wheel 220, and further obtain the flow speed of the air flow and the dust collection amount in the dust bag 300 according to the rotation speed of the wind wheel 220.

In addition, the magnetic member 240 may be located at a side of the wind wheel 220 away from the first housing 211, so that the magnetic member 240 is disposed near the sensing member 500, so as to avoid interference between the wind wheel 220 and the interaction between the magnetic member 240 and the sensing member 500, and ensure that the sensing member 500 can successfully detect the change of the magnetic field formed by the magnetic member 240.

In other embodiments, the magnetic member 240 may be a magnet block, and may be directly embedded in at least one blade of the wind wheel 220, and the magnetic member 240 may be located on a side of the blade away from the first housing 211.

In other embodiments, the sensing element 500 may also be a capacitive rotation speed sensor or a resistive rotation speed sensor, which can detect the rotation speed of the wind wheel 220 in real time.

It will be appreciated that when the magnetic member 240 is demagnetized, it can also be replaced by opening the first housing 211.

As shown in fig. 1 and 2, the dust collecting device further includes a display module 610. In some embodiments, the display module 610 may be embedded in an end of the main housing 110 near the cover 120 and exposed to the external environment for the user to view.

Of course, in other embodiments, the display module 610 may also be embedded in the circumferential sidewall of the main housing 110 and located outside the sidewall.

Referring to fig. 3 and fig. 4 together, in an embodiment, the display module 610 may be electrically connected to the sensing element 500. Specifically, the sensing element 500 may be connected to the connector male socket 510 through a wire, and the connector male socket 510 may be connected to the connector female socket connected to the display module 610, so as to electrically connect the display module 610 and the sensing element 500. It will be appreciated that the partition 111 may be provided with a second through hole 114 in communication with the second sub-chamber 1012 for wires to pass through so that the connector insert 510 is connected to the display module 610.

In an embodiment, the display module 610 may be used for displaying the dust collection amount in the dust bag 300, so that a user can intuitively know the dust collection amount in the dust bag 300, and the user can replace the dust bag 300 in time according to the dust collection amount displayed by the display module 610, so as to reduce the problem that the user cannot collect dust when the user goes out and the dust bag 300 is full. Wherein, the dust collection amount can be changed between 0% and 100%.

Referring again to fig. 7, in some embodiments, the display module 610 may be integrated with light emitting diodes (Light Emitting Diode, LEDs) of multiple colors. Each color LED can respectively correspond to a preset dust collection amount range, and the preset dust collection amount range corresponding to any color LED is different from the preset dust collection amount range corresponding to other color LEDs. When the dust collection amount of the dust bag 300 is within a preset dust collection amount range, the LED lamp of the corresponding color of the preset dust collection amount range is turned on, and the LEDs of other colors are in a non-lighting state. Thus, the user can accurately know the dust collection amount in the dust bag 300 according to the display of the LEDs of different colors.

In some embodiments, the display module 610 may be integrated with five colors of LEDs, and illustratively, the display module 610 may be integrated with green, blue, yellow, violet, and red LEDs. Accordingly, the dust collection amount of the dust bag 300 may be divided into five sections, which are respectively 0 to 20% (both end points 0 and 20% may be included), 20 to 40% (the maximum end point may be included, the minimum end point may be excluded), 40 to 60% (the maximum end point may be included, the minimum end point may be excluded), 60 to 80% (the maximum end point may be included, the minimum end point may be excluded), and 80 to 100% (the maximum end point may be included, the minimum end point may be excluded).

When the dust collection amount in the dust bag 300 is 0 to 20% (both end values 0 and 20% may be included), the green LED 611 of the display module 610 may be turned on, and the other color LEDs may be in a non-lighted state. When the dust collection amount in the dust bag 300 is 20% -40% (the maximum endpoint value may be included and the minimum endpoint value may not be included), the blue LED 612 of the display module 610 may be turned on, and the other color LEDs may be in a non-lighted state. When the dust collection amount in the dust bag 300 is 40% -60% (the maximum endpoint value may be included and the minimum endpoint value may not be included), the yellow LED613 of the display module 610 may be turned on, and the other color LEDs may be in an unlit state. When the dust collection amount in the dust bag 300 is 60% -80% (the maximum endpoint value may be included and the minimum endpoint value may not be included), the purple LED 614 of the display module 610 may be turned on, and the LEDs of other colors may be in a non-lighted state. When the dust collection amount in the dust bag 300 is 80% -100% (the maximum endpoint value may be included and the minimum endpoint value may not be included), the red LED 615 of the display module 610 may be turned on, and the LEDs of other colors may be in a non-lighting state.

In other embodiments, the display module 610 may be integrated with three, four, or six LEDs of various colors, where each color LED may correspond to a different range of dust collection amounts.

In an embodiment, the dust collection device further includes a signal amplification module 640, a signal processing module 650, and a plurality of LED driving modules 620. The input end of the signal amplification module 640 may be electrically connected to the sensing element 500, and the output end of the signal amplification module 640 may be connected to the input end of the signal processing module 650. The output end of the signal processing module 650 may be connected to a plurality of LED driving modules 620, and the plurality of LED driving modules 620 may be connected to LEDs of multiple colors in the display module 610 in a one-to-one correspondence manner, that is, one LED driving module 620 may be connected to one color LED. Illustratively, the dust collection device may include five LED driving modules 620, namely a first LED driving module 621, a second LED driving module 622, a third LED driving module 623, a fourth LED driving module 624, and a fifth LED driving module 625. The five LED driving modules can be respectively connected with the LEDs with five colors in a one-to-one correspondence manner. Illustratively, a first LED driver module 621 may be connected with the green LED 611, a second LED driver module 622 may be connected with the blue LED 612, a third LED driver module 623 may be connected with the yellow LED613, a fourth LED driver module 624 may be connected with the violet LED 614, and a fifth LED driver module 625 may be connected with the red LED 615. It is understood that each LED driving module 620 may operate at a different voltage range.

In some embodiments, the signal amplification module 640 may be a NIM2107F, LM chip, a LM321LV chip, a LM358LV chip, a LM324LV chip, or the like. The signal processing module 650 may be an a/D digital-to-analog conversion chip. The LED driving module 620 may be a switching tube, and the switching tube can set five different on voltages. It is understood that the on-voltage of the switching tube settings used by each LED driving module 620 are different.

In operation, when the dust collecting device is in operation, the fan 400 can drive the airflow in the dust bag 300 to flow and drive the wind wheel 220 in the wind wheel assembly 200. The sensing element 500 may detect the rotational speed of the rotor 220 in the rotor assembly 200 to obtain a sensing signal. The signal amplifying module 640 may be configured to amplify the sensing signal generated by the sensing element 500 and output a corresponding amplified signal. After the amplified signal is transmitted to the signal processing module 650, the signal processing module 650 may convert the amplified signal, specifically, the amplified signal (analog signal) into a corresponding digital signal. When the signal output by the signal processing module 650 is in the voltage range where the LED driving module 620 operates, the LED driving module 620 can be operated, and the LED driving module 620 drives the LED with the color connected to itself to light up, so as to display the dust collection amount. Illustratively, when the signal output by the signal processing module 650 is within the voltage operating range of the first LED driving module 621, the green LED 611 may be driven to light, which may indicate that the dust collection amount in the dust bag 300 is between 0 and 20%.

In other embodiments, the LED driver module 620 may be adaptively adjusted according to the number of color settings of the LEDs in the display module 610. Illustratively, the LED driving module 620 may also be configured as three, four, six, etc. as desired and equal to the color class of the LEDs in the display module 610.

It will be appreciated that the dust collection device may also include a main processor (not shown) and a memory (not shown). The main processor may be one of a central processing unit or a microprocessor. The main processor can be used for uniformly regulating and controlling the work of all electric components in the dust collecting device.

In addition, the dust collecting device further comprises a communication module 630, which can be used for realizing communication connection between the dust collecting device and equipment such as a mobile terminal. The communication module 630 may include, but is not limited to, at least one of a bluetooth module, a Wireless-Fidelity (WI-FI) network module, a third generation mobile communication technology (3rd Generation,3G) network module, a fourth generation mobile communication technology (the 4Generation mobile communication technology,4G) network module, or a fifth generation mobile communication technology (5th Generation Mobile Communication Technology,5G) network module.

In an embodiment, the dust collecting device may send the dust collecting amount in the dust bag 300 to the mobile terminal through the communication module 630, so that the user can check the dust collecting amount. The communication module 630 may send the amplified signal output by the amplifying module to the mobile terminal, and the mobile terminal may analyze and process the received signal to calculate a dust collection amount corresponding to the received signal, and display the dust collection amount on the mobile terminal for the user to check. Wherein, the dust collection amount displayed by the mobile terminal can be any value of 0-100%.

In other embodiments, the dust collection device may be in indirect communication with the mobile terminal via an intermediary device. For example, when the dust collecting device is applied to the base station, the dust collecting device may be communicatively connected to the mobile terminal through the surface cleaning apparatus. That is, the dust collecting device is communicatively connected to the surface cleaning apparatus, and the surface cleaning apparatus is communicatively connected to the mobile terminal.

In addition, when the sensing part 500 detects that the dust collection amount in the dust bag 300 is greater than or equal to the preset value, a reminding signal can be sent to the mobile terminal through the communication module 630 so as to remind the user to replace the dust bag 300 in time. In an embodiment, the preset value may be stored in the memory.

Of course, in other embodiments, the dust collecting device may be provided with at least two preset values, for example, the dust collecting device may include a first preset value and a second preset value, and the second preset value is greater than the first preset value. When the sensing piece 500 detects that the dust collection amount in the dust bag 300 is greater than or equal to the first preset value, the communication module 630 can send a reminding signal to the mobile terminal to remind the user to replace the dust bag 300 in time, and when the sensing piece 500 detects that the dust collection amount in the dust bag 300 is greater than or equal to the second preset value, the communication module 630 can send the reminding signal to the mobile terminal again. That is, the dust collecting device may send a plurality of reminding signals to the user to remind the user to replace the dust bag 300 in time. When the sensing member 500 detects that the dust bag 300 is full of dust, a reminding signal can be continuously sent to the mobile terminal through the communication module 630 to remind a user to replace the dust bag.

In addition, the dust collecting device can record the dust collecting frequency during the use of the user and the period of the user replacing the dust bag 300, and store the same in the memory. Therefore, the use habit of the user can be obtained according to the dust collection frequency of the user and the period of replacing the dust bag 300 by the user, and the corresponding reminding function can be generated according to the use habit of the user. In an embodiment, the processor may calculate, according to the dust collection frequency and the period of replacing the dust bag 300, the time for obtaining the next replacement of the dust bag 300, and may send a reminder instruction to the mobile terminal through the communication module 630 when the time is reached.

In some embodiments, the dust collection frequency may be obtained from the start-up frequency of the blower 400. The period of replacing the dust bag 300 may be obtained according to the period of taking out the dust bag 300 from the first sub-chamber 1011 by the user. In some embodiments, a detecting structure (not shown) such as a pressure sensor or a photoelectric sensor may be disposed in the first sub-chamber 1011, for detecting whether the dust bag 300 is in the first sub-chamber 1011, so as to obtain the period of replacing the dust bag 300 by the user.

Embodiments also provide a cleaning apparatus including the dust collecting device provided in the embodiments. The cleaning equipment can be one of a base station, a floor sweeping machine, a floor mopping machine or a floor washing machine and the like.

Illustratively, in some embodiments, the cleaning device may be a base station. The main body structure 100 in the dust collecting device may be a housing of a base station. When the dust bag enters the base station from the sweeper, the mopping machine or the floor washing machine, the input port 310 of the dust bag 300 can be communicated with the drain outlet of the sweeper, the mopping machine or the floor washing machine through a structure such as an air duct to provide a dust collecting function.
