Description

Technical Field

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0024] like Figures 1 to 6As shown, a multi-directional vacuum cleaner according to a first aspect embodiment of the present invention includes a housing 100, a suction module 400, a detection module, a shifting module 700, and a control module. The lower part of the housing 100 is provided with a suction chamber 110 and a plurality of suction ports 120 communicating with the suction chamber 110. The plurality of suction ports 120 are arranged circumferentially around the housing 100. The suction module 400 is disposed on the housing 100 and communicates with the suction chamber 110. The detection module is disposed on the housing 100 and is used to detect the suction chamber 110. The system determines whether there is an object in the circumferential direction of 00 and the object's location to form a directional signal. A shift module 700 is movably disposed in the housing 100. The shift module 700 can block the dust suction port 120 and allows any one of the dust suction ports 120 to communicate with the dust suction chamber 110. A control module is disposed in the housing 100 and is connected to both the detection module and the shift module 700 to control the shift module 700 to communicate with the corresponding dust suction port 120 and the dust suction chamber 110 based on the directional signal.

[0025] The housing 100 can be a vertical column or other irregular shape. Taking the vertical column structure as an example, the housing 100 can have a vertical accommodating cavity. The shift module 700 and the dust suction port 120 are usually located at the bottom of the housing 100. Specifically, there can be four dust suction ports 120, each of which is located in the front, back, left, and right directions respectively.

[0026] The control module can use a processor such as an MCU or CPU and its associated circuitry. The user sweeps the contaminants to any position of the multi-directional vacuum cleaner. The detection module detects the approach of an object in a certain direction and uses that position as the target position to form a position signal. The control module controls the shifting module 700 to operate based on the position signal. The shifting module 700 opens the suction port 120 corresponding to the target position, while the other suction ports 120 remain closed. This ensures that the suction module 400 can provide a sufficiently large negative pressure to the open suction ports 120 to adsorb dust, particles, floating hair, and other contaminants outside the suction ports 120. This application provides multi-directional vacuuming, which is convenient and reliable to use and improves the cleaning effect.

[0027] In some embodiments of the present invention, such as Figure 5 , 6As shown, the shift module 700 includes a mounting cover 710, a rotating disk 720, and a drive assembly 730. The mounting cover 710 and the drive assembly 730 are disposed in the housing 100. The rotating disk 720 is rotatably disposed within the housing 100. The rotating disk 720 is rotatably connected to the mounting cover 710 to enclose the dust collection chamber 110. The mounting cover 710 is provided with a connecting pipe 740. The connecting channel 741 in the connecting pipe 740 is connected to the dust collection chamber 110 and the suction module 400, respectively. The peripheral wall of the rotating disk 720 is provided with a dust collection port 721 that communicates with the dust collection chamber 110. The control module is connected to the drive assembly 730. The drive assembly 730 can drive the rotating disk 720 to rotate so that the dust collection port 721 communicates with any of the dust collection ports 120 and the peripheral wall of the rotating disk 720 blocks other dust collection ports 120.

[0028] Understandably, the rotating disk 720 is rotatably mounted on the inner wall of the bottom of the housing 100, and the mounting cover 710 is fixedly mounted on the housing 100. The rotating disk 720 has a dust collection groove, and the mounting cover 710 covers the groove of the rotating disk 720 to enclose the dust collection chamber 110. The peripheral wall of the rotating disk 720 is provided with a dust collection port 721. Under the drive of the drive assembly 730, the rotating disk 720 can rotate relative to the housing 100 and the mounting cover 710, so that the dust collection port 721 can move to the corresponding position and communicate with the corresponding dust collection port 120. The suction module 400 communicates with the dust collection chamber 110 through the connecting channel 741 in the connecting pipe 740, and provides negative pressure at the dust collection port 120 that communicates with the dust collection port 721, thereby adsorbing external pollutants.

[0029] In some embodiments of the present invention, such as Figure 6 As shown, the drive end of the drive assembly 730 is provided with a gear 731, and the outer peripheral wall of the rotating disk 720 is provided with a rack 732. The gear 731 meshes with the rack 732, and the drive assembly 730 drives the rotating disk 720 to rotate by driving the gear 731.

[0030] The drive component 730 can be a motor or a rotary cylinder. The drive component 730 drives the rotary disk 720 to rotate through the transmission structure of gear 731 and rack 732. It can control the rotation stroke relatively accurately, so that the control module can control the dust collection port 721 and the corresponding dust suction port 120 to be directly connected according to the orientation signal, ensuring the dust suction effect of the dust suction port 120.

[0031] In some embodiments of the present invention, such as Figure 5 , 6As shown, a ball bearing assembly 750 is provided between the inner wall surface of the bottom of the housing 100 and the rotating disk 720. The rotating disk 720 is rotatably disposed within the housing 100 via the ball bearing assembly 750. The ball bearing assembly 750 can reduce the friction between the inner wall surface of the bottom of the housing 100 and the outer wall surface of the rotating disk 720, making the rotation of the rotating disk 720 smoother and reducing the risk of jamming when the drive assembly 730 drives the rotating disk 720 to rotate.

[0032] Specifically, the ball bearing assembly 750 includes an annular bracket 751 and a plurality of ball bearings 752. The annular bracket 751 is disposed on the inner wall surface of the bottom of the housing 100, and the plurality of ball bearings 752 are arranged circumferentially along the annular bracket 751. The outer wall surface of the bottom of the rotating disk 720 is provided with an annular groove 722, and each ball bearing 752 is rolled and engaged in the groove 722 so that the rotating disk 720 is rotatably disposed within the housing 100.

[0033] The ball bearings 752 are evenly arranged along the circumferential direction of the annular bracket 751 to ensure that the support force provided at each position in the circumferential direction is balanced. The ball bearings 752 roll on the annular bracket 751, and when the rotating disk 720 rotates relative to the housing 100, the ball bearings 752 are confined to the track groove 722 to roll, reducing the friction between the rotating disk 720 and the housing 100.

[0034] In some embodiments of the present invention, the shift module 700 may also be a plurality of baffle assemblies, each baffle assembly being configured one-to-one with each suction port 120. The baffle assembly may include a baffle and a driving component. The driving component is connected to the baffle to drive the baffle to translate or rotate to open or close the suction port 120. The control module is connected to each driving component respectively, and the control module selects and controls the corresponding suction port 120 to open according to the orientation signal.

[0035] In some embodiments of the present invention, such as Figure 1 , 2 As shown in Figures 5 and 6, the detection module includes multiple infrared transceiver probes 600, which are arranged circumferentially around the housing 100 and are correspondingly positioned with respect to the dust extraction port 120.

[0036] Each infrared transceiver 600 can be embedded in the housing 100 and is located above the suction port 120 in a corresponding manner. Each infrared transceiver 600 has an infrared emitting head and an infrared receiving head. The infrared emitting head emits infrared light. When an object approaches the infrared transceiver 600 in that direction, the infrared light is reflected at the approaching object and received by the infrared receiving head to form a directional signal. The control module can determine which direction of the suction port 120 needs to be opened based on the directional signal fed back by the specific infrared transceiver 600.

[0037] In some embodiments of the present invention, the detection module may also be selected from ultrasonic sensors or visual camera sensors.

[0038] In some embodiments of the present invention, such as Figures 1 to 4 As shown, the housing 100 is provided with a purification air duct 130 and a fan 200 and a filter element 300, both located in the purification air duct 130. The housing 100 has an air inlet 140 and an air outlet 150, both of which are connected to the purification air duct 130. The filter element 300 is located between the air inlet 140 and the air outlet 150. The fan 200 can guide the airflow from the air inlet 140 into the purification air duct 130 and out from the air outlet 150.

[0039] It is understood that the multi-directional vacuum cleaner of this application can also have an air purification function. The fan 200 and the filter element 300 can be located above the suction module 400, the suction chamber 110, and the shift module 700 within the housing 100. The filter element 300 can be selected from high-efficiency particulate air (HEPA) filters. The filter element 300 spans the cross-section of the purification duct 130. The fan 200 can be located within the purification duct 130 to drive the airflow. The airflow entering the purification duct 130 from the air inlet 140 needs to be filtered by the filter element 300 before being output from the air outlet 150. The outside air circulates into the purification duct 130 and is filtered by the filter element 300 to remove particles and odors from the air, ensuring the freshness of the ambient air.

[0040] There can be multiple air inlets 140, and the air inlets 140 are located on the side of the housing 100, while the air outlet 150 can be located on the top of the housing 100. The housing 100 can be provided with a second dust filter 820 at the air inlet 140. The mesh structure of the second dust filter 820 can first isolate large particles on the airflow entering the purification air duct 130, thereby extending the service life of the filter element 300 and reducing maintenance costs.

[0041] The suction module 400 includes a dust collection box 410, a suction pump 420, and a dust filter assembly 430 disposed within the housing 100. The dust collection box 410 has a dust collection chamber 411, which is connected to the suction chamber 110. The dust filter assembly 430 defines at least a portion of a dust filter duct 431. The first end of the dust filter duct 431 is connected to the dust collection chamber 411 through a first dust filter screen 435 of the dust filter assembly 430, and the last end of the dust filter duct 431 is connected to the purification duct 130. The suction pump 420 can guide the airflow from the first end of the dust filter duct 431 to the last end of the dust filter duct 431. In the forward direction of the airflow in the purification duct 130, the connection point between the first end of the dust filter duct 431 and the purification duct 130 is located behind the filter element 300.

[0042] The suction pump 420 draws airflow through the dust duct 431, dust collection chamber 411, and suction chamber 110, creating a negative pressure at the open suction port 120. Dust, hair, and other pollutants enter the suction chamber 110 with the airflow and then enter the dust collection chamber 411. Due to the isolation provided by the first dust filter 435, the pollutants are isolated and stored in the dust collection chamber 411.

[0043] In traditional vacuum cleaners, the airflow passing through the dust collection chamber 411 is exhausted to the outside. However, the exhausted airflow still contains small dust particles and odors, posing a risk of environmental pollution. Therefore, in the vacuum cleaner of this application, the airflow flows from the dust filtration duct 431 to the purification duct 130. As the airflow moves forward in the purification duct 130, it undergoes secondary filtration through the filter element 300 to remove small dust particles and odors from the airflow before being exhausted to the outside, keeping the outside air fresh.

[0044] In some embodiments of the present invention, such as Figure 3 , 4 As shown, a support plate 810 is provided inside the housing 100. The support plate 810 defines an installation cavity 432 at the bottom. The suction pump 420 is located in the installation cavity 432. The support plate 810 is provided with an air inlet 433 and an air outlet 434, both of which are connected to the installation cavity 432. The air outlet 434 is connected to the purification air duct 130. The dust collection box 410 can be placed on the support plate 810. The dust filter assembly 430 also includes an exhaust pipe 412 disposed in the dust collection box 410. The exhaust pipe 412 is connected to the first dust filter 435 so that the first end of the exhaust channel 413 of the exhaust pipe 412 is connected to the dust collection cavity 411 through the first dust filter 435. The tail end of the exhaust channel 413 can be connected to the air inlet 433 so that the exhaust channel 413 and the installation cavity 432 constitute at least part of the dust filter air duct 431. It is understandable that the dust collection box 410 can be separated from the housing 100, thereby facilitating the cleaning of contaminants in the dust collection chamber 411. The support plate 810 can divide the accommodating cavity inside the housing 100 into upper and lower chambers. The support plate 810 can form an installation cavity 432 separated from the lower chamber through its own wall, thereby placing the suction pump 420 in the installation cavity 432, while components such as the suction module 400 and the shifting module 700 are located in the lower chamber.

[0045] When the dust collection box 410 is placed on the support plate 810, the tail end of the exhaust channel 413 is directly opposite the air inlet 433 to achieve connection. Specifically, a sealing ring can be set around the air inlet 433 or the tail end of the exhaust channel 413 to ensure airtightness. The suction pump 420 runs in the mounting cavity 432. The airflow of the dust collection chamber 411 can enter the exhaust channel 413 through the first dust filter 435 and flow to the mounting cavity 432, and flow into the purification air duct 130 from the air outlet 434.

[0046] The shift module 700 is provided with a connecting pipe 740. Specifically, the connecting pipe 740 can be provided on the mounting cover 710. One end of the connecting pipe 740 away from the mounting cover 710 passes through the support plate 810. The first end of the connecting channel 741 in the connecting pipe 740 is connected to the dust collection chamber 110. The dust collection box 410 is provided with a dust collection pipe 414. The tail end of the connecting channel 741 can be connected to the first end of the dust collection channel 415 in the dust collection pipe 414. The tail end of the dust collection channel 415 is connected to the dust collection chamber 411.

[0047] It is understandable that when the dust collection box 410 is placed on the support plate 810, the first end of the dust collection channel 415 can be directly aligned with the last end of the connecting channel 741 to achieve connection. Specifically, a sealing ring can be provided around the first end of the dust collection channel 415 or the last end of the connecting channel 741 to ensure airtightness.

[0048] In some embodiments of the present invention, the housing 100 is provided with a cover plate 160, a drawer cavity 170 and an insertion interface 180 communicating with the drawer cavity 170 above the support plate 810. The dust collection box 410 is inserted into the drawer cavity 170 to be detachably connected to the housing 100 and the dust collection box 410 can enter and exit the drawer cavity 170 through the insertion interface 180. The cover plate 160 is movably or detachably connected to the housing 100 to be able to open or close the insertion interface 180.

[0049] Specifically, the insertion interface 180 is located on the side wall of the housing 100. The dust collection box 410 can be inserted into the drawer cavity 170 to be detachably connected to the housing 100. Specifically, the drawer cavity 170 can be the same cavity as the upper cavity, and the purification air duct 130 can be formed directly by the drawer cavity 170 and the upper cavity. A sealing ring can be provided at the connection position of the edge of the housing 100 and the insertion interface 180 to ensure high air tightness. Alternatively, additional pipes can be provided in the upper cavity to define the purification air duct 130.

[0050] In some embodiments of the present invention, one side of the cover plate 160 can be connected to the housing 100 via a pivot, and the other side of the cover plate 160 can be connected to the housing 100 via a snap fastener or screw, so that the cover plate 160 can be flipped to open or close the insertion interface 180. In some embodiments of the present invention, the edge of the cover plate 160 can also be directly connected to the housing 100 via a snap fastener or screw. When it is necessary to open the insertion interface 180, the screws on the cover plate 160 can be removed or the cover plate 160 can be unfastened to separate the cover plate 160 from the housing 100.

[0051] The top of the dust collection box 410 may be provided with a top cover 440, which covers the top port of the dust collection box 410 to enclose the dust collection chamber 411. After the dust collection box 410 is separated from the housing 100, the user can open the top cover 440 to empty the pollutants in the dust collection chamber 411.

[0052] In some embodiments of the present invention, such as Figure 4 As shown, the dust collection box 410 is provided with an installation port 441 that communicates with the dust collection chamber 411. The dust collection box 410 is detachably provided with an end cover 450 that can open or close the installation port 441. The first dust filter 435 is tubular and can enter and exit the dust collection chamber 411 through the installation port 441. The first end of the first dust filter 435 is connected to the end cover 450, and the tail end of the first dust filter 435 is sleeved on the first end of the exhaust pipe 412 away from the inner wall of the dust collection box 410.

[0053] Specifically, the installation port 441 can be opened on the top cover 440, and the end cover 450 can be connected to the top cover 440 through a magnetic structure, a threaded structure or a rotating snap-fit ​​structure, making installation and disassembly convenient. The end cover 450 is connected to the first end of the tubular first dust filter 435, and the tail end of the first dust filter 435 is sleeved on the first end of the exhaust pipe 412, thereby isolating the inside of the first dust filter 435 from the dust collection chamber 411. Airflow can enter the inside of the first dust filter 435, while large dust particles remain in the dust collection chamber 411.

[0054] The exhaust pipe 412 is a frustum shape that is narrower at the top and wider at the bottom. The first dust filter 435 has a frustum groove in the middle of its tube that matches the top surface of the exhaust pipe 412. The first dust filter 435 can rotate relative to the top surface of the exhaust pipe 412.

[0055] According to a second aspect of the present invention, a control method is performed on a multi-directional vacuum cleaner disclosed in any of the above embodiments, the control method comprising: When the orientation signal is acquired, the orientation signal is used to indicate that there is an object at the target orientation of the housing 100; Control commands are derived from the azimuth signal; The shift module 700 is controlled to operate according to the control command so that the dust collection port 721 is connected to the dust suction port 120 corresponding to the target position and the dust suction chamber 110.

[0056] The detection module may include multiple infrared transceiver probes 600, which are arranged around the circumference of the housing 100 and correspond one-to-one with the dust extraction port 120.

[0057] When any one of the infrared transceiver probes 600 detects an object approaching from ahead, it generates a directional signal and outputs it to the control module. The control module can determine the target location of the approaching object based on which infrared transceiver probe 600 outputs the directional signal. Taking the shift module 700, which includes a mounting cover 710, a rotating disk 720, and a drive assembly 730, as an example, the shift module 700 can be equipped with an encoder. The encoder can record the actual rotation angle of the rotating disk 720. The control module can determine the dust collection port 721's dust collection location based on the signal representing the rotation angle fed back by the encoder. Based on the target location and the dust collection location, the required rotation angle is derived to generate a control command. The control module then controls the shift module 700 to operate according to the control command so that the dust collection port 721 and the suction port 120 corresponding to the target location are connected to the suction chamber 110.

[0058] The control method of this invention can detect the approach of an object in a certain direction and form a direction signal with that direction as the target direction. Based on the direction signal, the shift module 700 is controlled to open the dust suction port 120 corresponding to the target direction, so as to absorb dust, particles, floating hair and other pollutants outside the dust suction port 120. This application provides multi-directional dust suction, which is convenient and reliable to use and improves the cleaning effect.
