Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and in particular to a dust box assembly, a dust suction device, a cleaning equipment and a cleaning system. Background Art

[0002] The working principle of vacuuming by a sweeping machine includes using an electric motor to drive the blades to rotate at high speed, generating negative pressure in the sealed dust box, sucking dust from the surfaces of objects such as carpets and floors, and the dust is sucked into the filter along with the air. The dust is filtered by the filter element in the filter and collected by the dust box, and the clean air after filtration is discharged out of the sweeping machine.

[0003] After the filter has been working for a period of time, a large amount of dust will be adsorbed on the surface of the filter where dust enters. A large amount of dust attached to the filter surface will block the tiny filter pores on the filter surface, thereby affecting the filter's filtering capacity. Since some dust is in a non-dry state, the filter is prone to breed bacteria and mold in a humid environment, producing odor. If it is not cleaned and dried in time, bacteria, mold and odor will pollute the air during subsequent use. Summary of the invention

[0004] The present invention provides a dust box assembly, a dust suction device, a cleaning device and a cleaning system to realize the self-cleaning and self-drying functions of a filter and improve the technical problem of bacteria and mold generation on the filter.

[0005] To achieve the above-mentioned purpose and other related purposes, the first aspect of the present disclosure provides a dust box assembly, which is installed on a cleaning device, including a dust box, a filter and a cleaning and drying duct; the dust box is provided with an air inlet, an air suction port and an air blowing port; the filter is installed in the dust box, dividing the inner cavity of the dust box into a first chamber and a second chamber, the air inlet is located on the wall of the first chamber, and the air blowing port and the air suction port are located on the wall of the second chamber; one end of the cleaning and drying duct is connected to the second chamber through the air blowing port, and the other end is connected to the outside of the cleaning device, and an openable and closable wind shield is provided on the cleaning and drying duct or the air blowing port; in response to the opening of the wind shield, the cleaning and drying duct guides hot air into the second chamber to dry the filter.

[0006] In the above technical solution, a filter is arranged in the dust box, and the filter divides the dust box into a first chamber and a second chamber, the air inlet is located on the wall of the first chamber, and the blowing port and the suction port are located on the wall of the second chamber. Then the filter is located between the air inlet and the suction port, and when the suction port inhales air, it can be achieved that air is inhaled at the air inlet, the airflow inhales dust from the air inlet, and leaves the dust on the side of the filter close to the air inlet through the filter, and the clean air filtered by the filter is discharged from the suction port, completing the dust collection operation. By connecting the cleaning and drying air duct on the outside of the dust box, it is possible to introduce the wind flow into the inner cavity of the dust box, and because the cleaning and drying air duct is connected to the second chamber through the blowing port, and the blowing port is located on the wall of the second chamber, the wind entering from the blowing port can be blown from the cleaner side of the filter to the side where dust remains, and the dust blocked in the tiny filter sieve holes of the filter can be removed, thereby achieving the cleaning of the filter.

[0007] In addition, the hot air guided into the second chamber by the cleaning and drying air duct can be used to dry the filter and the dust box, and also has a certain function of cleaning the filter. The self-cleaning and self-drying process can be carried out in time after vacuuming is completed. Timely cleaning and drying can reduce the growth of bacteria and mold. Cleaning and drying can also be performed at regular intervals, or set to be performed at certain intervals. The above self-cleaning and self-drying processes can effectively reduce the generation of bacteria, mold and odor, and reduce pollution to the environment. Moreover, the self-cleaning and self-drying process does not require disassembly of the machine for manual cleaning of the filter, nor does it require manual drying. This technical solution can also increase the service life of the filter, reduce the frequency of replacing new filters, and reduce the replacement cost of consumables.

[0008] In one embodiment of the dust box assembly disclosed in the present invention, an openable dust collecting port is also provided on the wall of the first chamber. In response to the closing of the dust collecting port and the opening of the wind shield, a first air flow channel is formed between the cleaning and drying air duct and the dust collecting port. The cleaning and drying air duct guides hot air from the outer self-blowing port of the cleaning equipment through the first air flow channel to blow toward the filter to dry the filter.

[0009] In the above technical solution, the dust collecting port is used to collect dust temporarily stored in the dust box, that is, to discharge the dust from the dust box through the dust collecting port. After the wind shield is opened, a first airflow channel is formed between the cleaning and drying air duct and the dust collecting port. The hot air entering the air outlet dries the filter in the process of passing through the first airflow channel, and also has the function of cleaning the filter. During this process, the dust collecting port is closed. This setting can gather the hot air in the dust box, so that the filter and the hot air are fully combined to achieve the effect of improving the drying efficiency.

[0010] In one embodiment of the dust box assembly disclosed in the present invention, an openable and closable dust collecting port is also provided on the wall of the first chamber. In response to the opening of the dust collecting port and the wind shield, a second air flow channel is formed between the cleaning and drying air duct and the dust collecting port. The cleaning and drying air duct guides the air flow from the outer self-blowing port of the cleaning equipment through the second air flow channel to the filter, and then is discharged through the dust collecting port and the suction port.

[0011] In the above technical solution, the dust collecting port and the wind shield are opened at the same time, forming a second air flow channel between the cleaning and drying air duct and the dust collecting port. The airflow entering the blowing port completes the cleaning filter in the process of passing through the second air flow channel. At the same time, since the dust collecting port is open, the airflow in the second air flow channel can discharge the dust temporarily stored in the dust box through the dust collecting port, thereby realizing the two functions of self-cleaning filter and dust collection.

[0012] In one embodiment of the dust box assembly of the present disclosure, the cleaning and drying air duct is detachably connected to the cleaning device via a first plug-in structure and is in sealed communication with the dust box.

[0013] In the above technical solution, the cleaning and drying air duct is installed using the first plug-in structure, which can achieve the effect of quick disassembly and assembly, and has the advantages of compact structure and reliable connection.

[0014] In one embodiment of the dust box assembly disclosed herein, a second plug-in structure for detachably connecting with a cleaning device is also provided on the outer wall of the cleaning and drying air duct. The second plug-in structure is spaced apart from the first plug-in structure along the extension direction of the cleaning and drying air duct and is consistent with the disassembly and assembly direction of the first plug-in structure.

[0015] In the above technical solution, a second plug-in structure is added on the basis of the first plug-in structure connection, and the second plug-in structure and the first plug-in structure are spaced apart, so as to realize multiple connection positions between the cleaning and drying air duct and the cleaning equipment, thereby improving the reliability of the installation of the cleaning and drying air duct.

[0016] In one embodiment of the dust box assembly of the present disclosure, a fixed connection structure for fixing to a cleaning device is also provided on the outer wall of the cleaning and drying air duct.

[0017] In the above technical solution, a fixed connection structure is used for further connection and fixation. Since hot air will flow through the cleaning and drying air duct, this will cause the cleaning and drying air duct to change between hot and cold, and frequent thermal expansion and contraction will make the connection parts easy to loosen. By setting a fixed connection structure, the problem of loose connection caused by thermal expansion and contraction can be effectively alleviated.

[0018] In one embodiment of the dust box assembly of the present disclosure, a guide structure is provided on the communication channel between the cleaning and drying air duct and the blowing port.

[0019] In the above technical solution, the setting of the guide structure can guide the airflow to be diverted according to the shape of the guide structure, so that the hot air is evenly distributed on the filter. In addition, when the airflow passes through the guide structure, the cross-sectional area through which the airflow passes is reduced. According to the continuity equation, the cross-sectional area is reduced and the airflow velocity through the cross section increases. In summary, the guide structure can guide the airflow to be evenly diverted and increase the airflow velocity, thereby improving the efficiency and quality of self-cleaning and drying.

[0020] A second aspect of the present disclosure further provides a dust suction device, which includes a suction generator and any one of the dust box assemblies described above, wherein the suction generator is connected to the suction port.

[0023] In the above technical solution, the cleaning device including the dust suction device realizes the self-cleaning and self-drying functions of the filter. The self-cleaning and self-drying process can be carried out in time after the dust suction is completed. Timely cleaning and drying can reduce the growth of bacteria and mold. Cleaning and drying can also be performed regularly, or set to be performed at certain intervals. The above self-cleaning and self-drying processes can effectively reduce the generation of bacteria, mold and odor, and reduce pollution to the environment. It can also reduce the number of times the filter is cleaned, and can also reduce the replacement cost of the filter.

[0024] In one embodiment of the cleaning device disclosed herein, the base also includes a first vent, a second vent and a third vent arranged on the outer surface and at the bottom of the base, the first vent is connected to the air blowing port, the second vent is connected to the dust collecting port, and the third vent is connected to the air inlet.

[0025] In the above technical solution, by providing a first vent connected to the air blowing port on the outer surface of the cleaning device, the airflow is introduced into the dust box to spray and clean the filter. By providing a second vent connected to the dust collecting port on the outer surface of the cleaning device, the dust temporarily stored in the first chamber is collected outside the cleaning device to self-clean the dust box. By providing a third vent connected to the air inlet at the bottom of the cleaning device, the surface in contact with the bottom of the cleaning device is cleaned.

[0026] A fourth aspect of the present disclosure also provides a cleaning system, which includes the above-mentioned cleaning device and a base station compatible with the cleaning device.

[0027] In the above technical solution, the cleaning system of the cleaning device realizes the self-cleaning and self-drying functions of the filter, reduces the number of cleaning times, and reduces the replacement cost of the filter. It can effectively reduce the generation of bacteria, mold and odor, and reduce pollution to the environment.

[0028] In one embodiment of the cleaning system disclosed herein, the base station includes a blowing generator and a drying device, the drying device is used to heat the gas generated by the blowing generator, and the blowing generator includes an air outlet that can be communicated with the first ventilation port.

On the one hand, the dust attached to the filter can be blown into the first chamber to achieve self-cleaning of the filter. On the other hand, the dust in the first chamber can be blown into the external dust collecting device to achieve self-cleaning of the dust box. By arranging a drying device at the base station, the gas generated by the blowing generator can be heated to achieve the drying function of the filter. The self-cleaning and self-drying process can be carried out in time after the vacuuming is completed. Timely cleaning and drying can reduce the growth of bacteria and mold. Cleaning and drying can also be performed regularly, or set to be performed at certain intervals. The above self-cleaning and self-drying processes can effectively reduce the generation of bacteria, mold and odor, and reduce pollution to the environment.

The dust box assembly 100 includes a dust box 110, a filter 120 and a cleaning and drying air duct 150. The dust box 110 is divided into a first chamber 130 and a second chamber 140 by the filter 120. One end of the cleaning and drying air duct 150 is connected to the second chamber 140 through the blowing port 141, and the other end is connected to the outside of the cleaning device 1. The cleaning and drying air duct 150 can introduce hot air into the second chamber 140 of the dust box 110 through the blowing port 141, so the wind entering from the blowing port 141 can be blown from the cleaner side of the filter 120 to the side where dust remains, and the dust blocked in the tiny filter mesh of the filter 120 can be removed to clean the filter 120. In addition, the hot air guided into the second chamber 140 by the cleaning and drying air duct 150 can dry the filter 120, and can also dry the dust box 110, and also has a certain function of cleaning the filter 120. The self-cleaning and self-drying process can be performed promptly after vacuuming is completed, regularly, or at regular intervals, thereby effectively reducing the generation of bacteria, mold and odor and reducing pollution to the environment.

[0049] See also Figure 7 and Fig.10 The dust box assembly 100 involved in the present disclosure is installed on the cleaning device 1. The cleaning device 1 involved in the present disclosure can be a cleaning robot. The cleaning robot includes a floor scrubber, a floor sweeper, a cleaning robot, etc., but is not limited thereto. Taking the cleaning robot as an example, in order to exert its cleaning function, the cleaning device 1 at least includes a dust suction device 10 for collecting and removing dust on the ground. The dust suction device 10 includes a dust box assembly 100 and a suction generator 200 connected to the dust box assembly 100. The suction generator 200 generates negative pressure by high-speed rotation to suck dust into the dust box assembly 100. In order to improve the dust suction efficiency, the dust is concentrated in advance. In some embodiments, the dust suction device 10 is also equipped with cleaning parts such as a roller brush.

[0050] In some embodiments, the cleaning device 1 also has a wet cleaning device for realizing the wet cleaning function, and the wet cleaning device includes a cleaning head, a liquid storage tank, a pump body, and a pipeline assembly.

[0051] See also Figure 1 to Figure 2 In an example of the dust box assembly 100 involved in the present disclosure, the dust box assembly 100 is installed on the cleaning device 1, and includes a dust box 110, a filter 120, and a cleaning and drying air duct 150. The shape of the dust box 110 is not limited, for example, it can be a square, a circle, a polygon or other irregular shapes. The shape of the dust box 110 in this embodiment is roughly a horizontally placed polygonal shape. This setting can be reasonably arranged with other components in the cleaning device 1 to achieve a higher utilization rate in a limited space.

[0052] See also Figure 1 to Figure 2 , the filter 120 is installed in the dust box 110, and the inner cavity of the dust box 110 is divided into a first chamber 130 and a second chamber 140. The first chamber 130 and the second chamber 140 are connected through the pores of the filter 120. The installation position of the filter 120 is not limited, for example, it can be placed horizontally, vertically, or at a certain angle to the horizontal direction. When the filter 120 is placed horizontally, the first chamber 130 and the second chamber 140 are arranged up and down; when the filter 120 is placed vertically, the first chamber 130 and the second chamber 140 are arranged front and back; when the filter 120 is placed at a certain angle to the horizontal direction, the first chamber 130 and the second chamber 140 are arranged at a certain angle. There are many ways to install the filter 120, including but not limited to threaded connection, card connection or plug-in connection, as long as the first chamber 130 and the second chamber 140 can be isolated, fixed in the dust box 110, and the connection with the dust box 110 can be sealed.

[0053] See also Figure 1 to Figure 2In this embodiment, the filter 120 includes a filter element 121 and a filter element mounting seat 122, and the filter element 121 is detachably mounted on the filter element mounting seat 122. The filter element 121 is configured to be detachable, which is convenient for cleaning and replacing the filter element 121. In particular, when replacement is required, only the filter element 121 needs to be replaced, and there is no need to replace the entire filter 120. In addition, this setting facilitates the adaptive design of the filter element mounting seat 122, reduces the difficulty of design and processing, and adapts to the space in the dust box 110 and the shape of the filter element 121. There are many options for the material of the filter element 121, including but not limited to HEPA (High Efficiency Particulate Air) filter, activated carbon filter, polyester fiber filter or nylon fiber filter.

[0054] See also Figures 1 to 3 , the dust box 110 is provided with an air inlet 131, an air suction port 142 and an air blowing port 141. The air inlet 131 is located on the wall of the first chamber 130, and the air blowing port 141 and the air suction port 142 are located on the wall of the second chamber 140. The opening positions of the air inlet 131, the air blowing port 141 and the air suction port 142 are not limited. For example, the air inlet 131 can be opened on the side wall or bottom wall of the first chamber 130, and the air blowing port 141 and the air suction port 142 can be opened on the side wall or bottom wall of the second chamber 140. It should be noted that the air inlet 131, the air blowing port 141 and the air suction port 142 are all openable and closable, and different work tasks can be achieved by controlling the opening and closing. In some embodiments, the openability of the air inlet 131, the air blowing port 141, and the air suction port 142 is controlled by an openable and closable opening and closing structure, and the opening and closing structure can be arranged on the inner side or outer side of the wall body at the opening of the air inlet 131, the air blowing port 141, and the air suction port 142, as well as other positions capable of controlling the opening and closing. For example, an openable and closable first baffle 133 is arranged on the inner side of the wall body at the opening of the air inlet 131; and an openable and closable baffle is arranged on the wall body at the opening of the air suction port 142. The opening of the opening and closing structure arranged on the air inlet 131, the air blowing port 141, and the air suction port 142 can be achieved by the high-pressure airflow provided by an external fan, electrical control or mechanical control, etc., and the closing of the opening and closing structure arranged on the air inlet 131, the air blowing port 141, and the air suction port 142 can be achieved by self-weight, spring reset, electrical control or mechanical control, etc., without limitation.

[0055] See also Figure 2The suction generator 200 draws air at the air inlet 142 to suck dust from the air inlet 131. At this time, the air inlet 131, the first chamber 130, the second chamber 140 and the air inlet 142 form a dust suction channel. Dust enters the first chamber 130 from the air inlet 131, and the filter 120 leaves the dust in the first chamber 130. At the same time, the clean air filtered by the filter 120 enters the second chamber 140 through the pores and is discharged from the air inlet 142 to achieve dust suction.

[0056] See also Figure 1 to Figure 2 The dust box assembly 100 also includes a cleaning and drying air duct 150, one end of which is connected to the second chamber 140 through the blowing port 141, and the other end is connected to the outside of the cleaning device 1. The installation position of the cleaning and drying air duct 150 is not limited, and it can be directly connected to the dust box 110 or connected to other components, as long as one end of the cleaning and drying air duct 150 can be connected to the second chamber 140 through the blowing port 141. An openable and closable windshield 151 is provided on the cleaning and drying air duct 150 or the blowing port 141. The installation position of the windshield 151 is not limited, for example, it can be installed in the cleaning and drying air duct 150, or it can be installed on the blowing port 141. The material of the windshield 151 is not limited, and it can be plastic, metal or soft rubber, etc. The windshield 151 in this embodiment is made of soft rubber, such as silicone or rubber, because the soft rubber is elastic and can better fit the mating surface to form a good sealing effect, which is conducive to maintaining the airtightness of the dust box 110, so that there is a higher negative pressure in the dust box 110 to achieve an efficient dust collection effect. The soft rubber material also has high heat resistance and anti-aging properties, and can be used for a long time in a high temperature environment without aging or becoming brittle, thereby increasing the service life of the windshield 151. The opening of the windshield 151 can be achieved by the high-pressure airflow provided by an external fan, electrical control or mechanical control, etc. The closing of the windshield 151 can be achieved by self-weight, spring reset, electrical control or mechanical control, etc., which is not limited.

[0057] See also Figure 2In one embodiment, the intelligent control system detects that the cleaning device 1 is in a state of stopping the dust collection operation, and can perform self-cleaning or self-drying operations, and can control the windshield 151 to open according to the received command. In response to the opening of the windshield 151, the air outlet 141 is opened, and the air outlet 141, the second chamber 140 and the first chamber 130 form a cleaning channel. The airflow enters the side of the filter 120 facing the second chamber 140 at the air outlet 141. When the airflow enters the first chamber 130 through the pores of the filter 120, the dust attached to the pores and the side of the filter 120 facing the first chamber 130 can be blown into the first chamber 130, completing the work of self-cleaning the filter 120. In addition, the airflow for cleaning the filter 120 is blown from the back of the filter 120 to the front of the filter 120, that is, it can be blown from the cleaner side of the filter 120 to the side with dust, so as to achieve the best cleaning effect. It should be noted that the definition of the back and front of the filter 120 is: during cleaning, dust is sucked into the dust box 110 through the air inlet 131 of the dust box 110, and the filter 120 performs filtering. At this time, the filtering surface of the filter 120 is the front surface, and the opposite surface is the back surface. In addition, the airflow entering from the air outlet 141 can be provided by connecting the air outlet 141 to the air generator, or by connecting the suction device on the wall of the first chamber 130, and there is no limitation on this.

[0058] See also Figure 1 to Figure 2 A device capable of heating the airflow is arranged inside or outside the cleaning device 1 to heat the airflow entering the cleaning channel into hot air. The cleaning and drying air duct 150 guides the hot air into the second chamber 140, and then enters the first chamber 130 through the pores of the filter 120. This process can realize self-drying of the filter 120, and can also dry the dust box 110, and also has a certain function of cleaning the filter 120.

[0059] Considering that dust in a non-dry state will be attached to the filter 120 after the vacuuming work is completed. If the filter 120 is cleaned and dried after accumulating several vacuuming operations instead of being cleaned and dried in time, it is easy for bacteria and mold to grow in a humid environment, and produce odor. If manual cleaning and drying are performed in time after each vacuuming, the manual workload will increase. In one embodiment, the self-cleaning and self-drying process can be performed in time after the vacuuming is completed. Timely cleaning and drying can reduce the growth of bacteria and mold. It replaces manual cleaning and manual drying, reducing the manual workload. In some other embodiments, cleaning and drying can also be performed regularly, such as cleaning and drying at a certain time every day. In some other embodiments, it can also be set to be performed once every certain time interval, and the time interval can be a certain time interval between cleaning and drying and vacuuming operations, or a certain time interval between multiple cleaning and drying operations. The above self-cleaning and self-drying processes can effectively reduce the generation of bacteria, mold and odor, and reduce pollution to the environment. Moreover, the self-cleaning and self-drying process does not require disassembling the machine to manually clean the filter 120, nor does it require manual drying. This technical solution can also increase the service life of the filter 120, reduce the frequency of replacing the filter 120 with a new one, and reduce the replacement cost of consumables.
