In the description of the present disclosure, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "coupled" are to be construed broadly and can include, for example, fixed and removable connections; can be mechanically or electrically connected; the connection can be direct connection or indirect connection through an intermediate medium; there may be communication between the interiors of the two elements. The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

Figure 1 illustrates a cross-sectional schematic view of a sweeper 100 according to some embodiments of the present disclosure. Figure 2 illustrates a partial structural schematic of the sweeper 100, according to some embodiments of the present disclosure. Figure 3 illustrates a partially constructed rear view of the sweeper 100, in accordance with some embodiments of the present disclosure. It will be appreciated by those skilled in the art that the cross-sectional view of the sweeper 100 shown in figure 1 is merely schematic, wherein components distributed across different sections of the sweeper 100 are shown in the same cross-sectional view for clarity, and the components are shown in a schematic, not necessarily physical form. For example, the fan 40 need not be located in the cross-section shown in FIG. 1, and the graphical representation of the fan 40 is schematic, rather than an actual cross-sectional configuration. For another example, the outlet does not have to be located on the cross section shown in fig. 1, and the flow path of the gas does not have to be a practical one.

As shown in fig. 1-3, the sweeper 100 may include a housing 10, a positive ion releaser array 20 and/or a negative ion releaser array 30, and a fan 40. The housing 10 may include an air inlet 11 and an air outlet 12. The positive ion releaser array 20 is provided in the housing 10 and may include at least one positive ion releaser for releasing positive ions. The negative ion discharger array 30 is provided in the housing 10, and may include at least one negative ion discharger for discharging negative ions. The positive ion releaser array 20 and the negative ion releaser array 30 are oppositely arranged on the base 14, and the fan 40 can be used for driving air flow to enter the air inlet 11 from the ground, and the air flow is discharged from the air outlet 12 after passing through the positive ion releaser array 20 and the negative ion releaser array 30.

As shown in fig. 1-3, in some embodiments of the present disclosure, the housing 10 may be flat and easy to access into and out of low environments (e.g., under a bed, under a sofa, etc.) to sanitize ground and air in locations that are not easily cleaned. The air inlet 11 is arranged at the bottom of the shell 10, and the air outlet 12 is arranged at the side surface of the shell 10, so that the detention time of the sucked air flow between the positive ion releaser array 20 and the negative ion releaser array 30 is prolonged, the mixing of air and positive and negative ions is promoted, the probability that germ particles adsorb the positive and negative ions or collide with the positive and negative ions is improved, and better sterilization and purification effects are achieved.

As shown in fig. 1-3, in some embodiments of the present disclosure, the housing 10 may further include a cavity 13 between the air inlet 11 and the air outlet 12. The positive ion releaser array 20 and the negative ion releaser array 30 release positive ions and negative ions to the cavity 13, a high-concentration plasma region is formed in the cavity 13, and airflow is mixed with the positive ions and the negative ions through the high-concentration plasma region, so that the probability that germ particles adsorb the positive ions and the negative ions or collide with the positive ions and the negative ions is improved, and better sterilization and purification effects are achieved.

In some embodiments of the present disclosure, the positive ion releaser array 20 and/or the negative ion releaser array 30 may comprise micro-nano conductive fiber clusters. The micro-nano conductive fiber cluster comprises at least one of the following components: one or more of carbon fibers, graphite fibers, metal fibers, glass fibers, ceramic fibers, short tungsten filaments, carbon fiber-doped polypropylene or polyethylene filaments; micro-nano fibers with the number within the range of 1000-1000000; or micro-nanofibers having a diameter in the range of 10 nanometers to 100 micrometers.

As shown in fig. 1 to 3, in some embodiments of the present disclosure, the positive ion releaser array 20 is linearly arranged, and the negative ion releaser array 30 is linearly arranged and disposed opposite to the positive ion releaser array 20.

It will be understood by those skilled in the art that although in some embodiments of the present disclosure, the positive ion releaser array 20 and the negative ion releaser array 30 are both arranged in a linear arrangement, this is merely exemplary, and the positive ion releaser array may further comprise at least one of the following arrangements: arc-shaped arrangement, fold-shaped arrangement, rectangular arrangement, circular arrangement and polygonal arrangement. Similarly, the negative ion releaser array 30 also comprises at least one of the following arrangements: arc-shaped arrangement, fold-shaped arrangement, rectangular arrangement, circular arrangement and polygonal arrangement.

It will be understood by those skilled in the art that although the sweeper 100 in the embodiment of the present disclosure includes the positive ion releaser array 20 and the negative ion releaser array 30, the sweeper 100 may include only the positive ion releaser array 20 or only the negative ion releaser array 30.

In some embodiments of the present disclosure, the sweeper 100 may also include a screen 50. A filter screen 50 is disposed in the housing 10 at the air inlet 11 for filtering particles in the air flow. In the working process of the sweeper, dust and air sucked by the sweeper can be filtered by the filter screen 50 and then enter the areas where the positive ion releaser array 20 and the negative ion releaser array 30 are located, so that the phenomenon that excessive dust and excessively large particles are attached to the positive ion releaser array 20 and the negative ion releaser array 30 can be effectively avoided, and the service life of equipment is influenced.

As shown in fig. 1-3, in some embodiments of the present disclosure, the sweeper 100 may further include a cleaning mechanism 60 disposed within the housing 10. The cleaning mechanism 60 may include a driving motor 61 and a cleaning member 62. The cleaning member 62 is connected to an output end of the driving motor 61 and is rotated by the driving motor 61 to clean the positive ion discharger array 20 and the negative ion discharger array 30. In some embodiments of the present disclosure, the cleaning members 62 may comprise sheets or rods of insulating material, such as plastic sheets, plastic rods, rubber sheets or rods, and the like. In some embodiments, the drive motor 61 may drive the cleaning members 62 in an oscillating, linear, or curvilinear motion.

It will be understood by those skilled in the art that although the cleaning member 62 shown in fig. 1 to 3 is a cleaning rod, this is only an exemplary structure, and the cleaning member 62 may also be a cleaning sheet, a cleaning brush, or the like, which can remove dust and particles attached to the positive ion discharger array 20 and the negative ion discharger array 30.

In the using process, dust or other impurities are easily deposited at the tips of the micro-nano conductive fiber clusters of the positive ion releaser array 20 and the negative ion releaser array 30, and the ion generation efficiency is influenced. The cleaning member 62 of the cleaning mechanism 60 can sweep the tips of the micro-nano conductive fiber clusters of the positive ion releaser array 20 and the negative ion releaser array 30 under the driving of the output end movement (for example, linear movement or arc movement) of the motor 61, so as to clean the discharge tips, sweep dust or other impurities, greatly improve the ion generation efficiency, and significantly prolong the service life of the ion releaser.

As shown in fig. 1-3, in some embodiments of the present disclosure, the sweeper 100 further includes a power supply 70 operable to supply power to the positive ion ejector array 20 and the negative ion ejector array 30 to eject positive ions and negative ions. In some embodiments of the present disclosure, the air is ionized by high voltage discharge to generate a large number of electrons and ions, and the energy generated by the collision and annihilation of these positive and negative ions can decompose microorganisms in the air to achieve a killing effect. In addition, the neutral active particles in the plasma can also effectively kill microorganisms in the air. In addition, the particulate matters with different charges in the air can be mutually attracted under the action of positive and negative ions, and the particulate matters can be changed into larger particle sizes from small particle sizes, so that the particulate matters are converted into dust fall, and the dust removal requirement is met.

As shown in fig. 1-3, in some embodiments of the present disclosure, the sweeper 100 further includes a sweeping mechanism. The sweeping mechanism may include a sweeping motor (not shown) and a sweeping assembly 90. The sweeping assembly 90 is connected with the output end of the sweeping motor, and the sweeping assembly 90 is at least partially exposed from the bottom surface or the side surface of the casing and is used for sweeping the ground under the driving of the sweeping motor.

In some embodiments of the present disclosure, the sweeping assembly 90 may include a first brush head 91 and/or a roller brush 92, and the first brush head 91 and the roller brush 92 are driven by the sweeping motor to rotate, so as to sweep dust on a road surface passed by the sweeper 100 into the dust box 80 of the sweeper 100, so as to complete the floor sweeping. The dust box 80 is arranged between the filter screen 50 and the air inlet 11, and can prevent dust from blocking the filter screen 50 and affecting the air purification effect.

It will be appreciated by those skilled in the art that although the sweeping assembly described in the embodiments of the present disclosure is a rotating brush head, this is merely an exemplary configuration, and the sweeping assembly may also be a swinging brush head or other structure capable of sweeping dust. Similarly, one skilled in the art will appreciate that although one sweeping assembly is shown in figure 1, a plurality of sweeping assemblies can be provided.

As shown in fig. 1-3, in some embodiments of the present disclosure, the sweeper 100 may further include a motion mechanism 101 and a controller (not shown). The motion mechanism 101 can be used to drive the sweeper 100 over a floor surface. The controller can control the movement mechanism 101 to drive the sweeper 100 to move along a predetermined path or a traverse path, and can be used to control the sweeping mechanism 90 to sweep the ground.

In some embodiments of the present disclosure, the movement mechanism 101 may include a movement motor (not shown in the figures) and a movement wheel 1011. The motion motor drives the motion wheel 1011 to rotate under the control of the controller, so as to drive the sweeper 100 to move according to a preset route, so as to sweep the ground and kill air. For example, a controller may be provided to automatically navigate, automatically set a cleaning route through a program built in the controller, and control the moving motor to drive the moving wheel 1011 to clean and kill according to the cleaning route. For another example, a route map may also be manually imported, and the controller controls the motion motor of the sweeper to drive the motion wheel 1011 to move, so as to drive the sweeper 100 to sweep and kill according to the manually imported route.

Those skilled in the art will appreciate that while the motion mechanism in some embodiments of the present disclosure may include a motion motor and a motion wheel, this is merely exemplary and the motion mechanism may also include only a motion wheel. The movement mechanism can move by being pushed by external force, thereby cleaning and killing the ground. In some embodiments, for example, the sweeper 100 may be a hand sweeper, and may be powered or unpowered. In some embodiments, the sweeper 100 may be a sweeping robot capable of automatically sweeping the floor under the control of a controller.

Fig. 4 shows a partial schematic structural view of a sweeper 300 according to other embodiments of the present disclosure. Figure 5 illustrates a rear view of a portion of a sweeper 300 according to further embodiments of the present disclosure.

In other embodiments of the present disclosure, as shown in fig. 4 and 5, the cleaning mechanism 360 may further include a transmission mechanism 363, and the transmission mechanism 363 is connected to an output end of the driving motor 361 and moves under the driving of the driving motor 361. The cleaning member 362 is connected with the transmission mechanism 363, and cleans the positive ion releaser array 320 and the negative ion releaser array 330 under the driving of the transmission mechanism 363. In other embodiments of the present disclosure, the drive mechanism 363 can be used to move the cleaning members linearly, rotationally, oscillatingly, or curvilinearly to sweep the ends of the positive ion ejector array 320 and the negative ion ejector array 330.

As shown in fig. 4 and 5, in some embodiments of the present disclosure, the transmission mechanism 363 may include a driving wheel 3631, a driving belt 3632, and a driven wheel 3633. The driving wheel 3631 is connected with an output end of the driving motor 361 to be rotated by the driving motor 361. The driving belt 3632 is sleeved on the driving wheel 3631, the driven wheel 3633 is connected with the driving wheel 3631 through the driving belt 3632 to rotate under the driving of the driving wheel 3631, and the cleaning piece 362 is arranged on the driven wheel 3633.

In the working process, the fan 340 draws the airflow into the housing, the airflow enters from the air inlet 311, is primarily filtered by the dust box 380 and the filter screen 350, enters the areas where the positive ion releaser array 320 and the negative ion releaser array 330 are located, and is discharged from the air outlet after being killed. The driving motor 361 drives the driving wheel 3631 to rotate, and in turn drives the driven wheel 3633 through the driving belt 3632, so that the cleaning member 362 on the driven wheel 3633 can sweep over the ends of the positive ion releaser array 320 and the negative ion releaser array 330, thereby cleaning the same.

Fig. 6 shows a schematic view of a portion of a sweeper 500 according to other embodiments of the present disclosure. Figure 7 illustrates a rear view of a portion of a sweeper 500 according to further embodiments of the present disclosure.

As shown in fig. 6 and 7, in other embodiments of the present disclosure, the transmission mechanism 563 may include a lead screw 5631 and a slider (e.g., a nut) 5632 that cooperates with the lead screw 5631. One end of the screw rod 5631 is connected to the output end of the driving motor 561 at the mounting seat 5633, and is rotatably connected to the mounting seat 5633 through a bearing penetrating the mounting seat 5633. The cleaning piece 562 is fixedly connected with a slide block 5632 sleeved on the screw rod 5631. The motor 561 may be used to drive the screw 5631 to rotate forward or backward about its axis, thereby driving the slider 5632 to move, e.g., forward or backward, and the cleaning member 562 to clean the positive ion discharger array 520 and the negative ion discharger array 530.

In the working process, the fan 540 draws the airflow into the housing, the airflow enters from the air inlet 511, enters the areas where the positive ion releaser array 520 and the negative ion releaser array 530 are located after primary filtration through the dust box 580 and the filter screen 550, and is discharged from the air outlet after disinfection. The screw 5631 of the driving motor 561 rotates forward or backward about its axis to drive the slider 5632 to move, for example, forward or backward, and the cleaning member 562 cleans the positive ion discharger array 520 and the negative ion discharger array 530 accordingly.

Because the ground can deposit dust and sundries, bacteria, microorganisms and the like are easy to live and breed, and the environment is an area which is easy to seriously pollute the indoor environment but difficult to clean. Traditional machine of sweeping floor can only clear away dust and debris, but can't kill bacterium and microorganism for bacterium and microorganism continue to survive and breed through the air outlet discharge. According to the sweeper disclosed by the embodiment of the disclosure, for example, the sweeper 100, 300 or 500 can efficiently kill bacteria, microbes and the like while sweeping dust and sundries, thoroughly clean the ground, including physical cleaning and biological cleaning, provide good indoor environment for production and life of people, effectively reduce the spread of viruses, germs and microbes, avoid cross infection, avoid allergen proliferation and the like.

As the usage time increases, the efficiency of the positive ion releaser array (e.g., the positive ion releaser array 20, the positive ion releaser array 320, the positive ion releaser array 520) and the negative ion releaser array (e.g., the negative ion releaser array 30, the negative ion releaser array 330, the negative ion releaser array 530) decreases gradually due to dust accumulation, and the cleaning of the positive ion releaser array (e.g., the positive ion releaser array 20, the positive ion releaser array 320, the positive ion releaser array 520) and the negative ion releaser array (e.g., the negative ion releaser array 30, the negative ion releaser array 330, the negative ion releaser array 530) by the cleaning mechanism (e.g., the cleaning mechanism 60, the cleaning mechanism 360, the cleaning mechanism 560) can enable sweeping to realize dust fall, sterilization and air purification while maintaining the killing efficiency without attenuation, thereby greatly prolonging the service life of the equipment.

It should be understood that the above-described embodiments are merely exemplary embodiments of the present disclosure, and are not intended to limit the present disclosure, and that any modification, equivalent replacement, or improvement made within the spirit and principle of the present disclosure should be included in the scope of protection of the present disclosure.
