In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, for static electricity generated on a dust collector, a static electricity conducting structure is generally arranged on the dust collector, and a user contacts the static electricity conducting structure on the dust collector to act as a static electricity conducting path between the static electricity and the ground so as to conduct the static electricity to the ground. However, since the operating position of the vacuum cleaner is changed, the user cannot be guaranteed to contact the static electricity conducting structure on the vacuum cleaner, and the static electricity removing effect is not good. In order to solve the problems in the prior art, in some exemplary embodiments of the present invention, an ion generating device is installed on a body of a vacuum cleaner, an ion generating unit in the ion generating device is disposed in a static electricity generating region on the body, and the ion generating unit in the ion generating device generates ions, so that static electricity generated during operation of the vacuum cleaner can be neutralized, static electricity can be effectively removed without depending on a static electricity conducting path, and thus, the integral antistatic property of the body can be ensured.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1a is a schematic view of an overall structure of a vacuum cleaner according to an exemplary embodiment of the present invention. As shown in fig. 1a, the vacuum cleaner 00 in this embodiment may include a main body 10. The main body 10 includes, but is not limited to, a main cleaner body 50 and a dust suction part 90. The cleaner main body 50 is provided with a dust suction barrel 60, and the dust suction part 90 is connected with the dust suction barrel 60.

In the present embodiment, the type of the cleaner is not limited, and examples thereof include an upright type cleaner, a canister type cleaner, and a hand-held type cleaner. The shape of the main body 10 may be different depending on the type of the cleaner.

The main body of the hand-held cleaner shown in fig. 1a will be described in detail below by taking the main body as an example. It should be noted that the main body of the handheld vacuum cleaner shown in fig. 1a is only an example, and the main body of the vacuum cleaner in this embodiment is not limited thereto.

As shown in fig. 1a, the dust suction part 90 may include a dust suction extension pipe 80 and a dust suction assembly 70, wherein one end of the dust suction extension pipe 80 is connected to the dust suction barrel 60, and the other end is connected to the dust suction assembly 70. Optionally, the cleaning assembly includes, but is not limited to, a floor brush 71 and a cleaning head 72, the floor brush 71 being mounted on the cleaning head 72. When the dust collector executes a dust collection task, the floor brush 71 moves relative to the surface to be cleaned, so that objects such as dust, bacteria and the like on the surface to be cleaned are separated from the surface to be cleaned, and enter the dust collection head 72 under the action of dust collection wind generated by the operation of the dust collector main machine 50, and the objects entering the dust collection head 72 continue to move into the dust collection barrel 60 under the action of the dust collection wind.

In the working process of the dust collector, the friction, peeling, extrusion, induction and the like between objects such as dust, bacteria and the like and between the objects and a dust collector component in the movement process enable charges with different properties to be accumulated on the surface of the body 10 of the dust collector, and when the charges are accumulated to a certain degree, static electricity is generated. The static electricity generating region of the body 10 is a region where static electricity is generated during the operation of the cleaner, and the region has static electricity adsorption and discharge phenomena, which require static electricity removal. The static electricity generating area may be different according to the type and structure of the vacuum cleaner, for example, the static electricity generating area may be a dust collecting barrel 60 on the main body of the vacuum cleaner, an air inlet 61 connected to the dust collecting barrel 60 on the main body 50 of the vacuum cleaner, or other areas on the main body 10.

Fig. 1b is a schematic structural diagram of a main body of a vacuum cleaner according to an exemplary embodiment of the present invention. In this embodiment, the cleaner comprises, in addition to the basic components, an ion generating device 20. As shown in fig. 1b, the ion generating device 20 is mounted on the body 10 in a fixed manner, or in a movable manner, such as a detachable manner, and the mounting manner can be selected according to actual needs. As shown in fig. 1b, the ion generating device 20 may be mounted on the main body 50 of the cleaner, preferably, at a position on the main body 50 of the cleaner adjacent to the dust collecting bucket 60, and of course, may be mounted at other positions on the main body 10 according to the layout requirement of the main body 10, which is not limited in this embodiment. It should be understood that the installation position of the ion generating device 20 refers to the installation position of the main body of the ion generating device. The ion generating device 20 includes a plurality of sets of ion generating units 30, and the plurality of sets of ion generating units 30 are disposed in a static electricity generating region on the body 10. One or more static electricity generating regions may be provided on the main body 10, and when there are a plurality of static electricity generating regions on the main body 10, the ion generating unit 30 may be provided in each static electricity generating region. The ion generating unit 30 can generate a large amount of ions by utilizing air ionization, and since the surfaces of objects such as dust, bacteria and the like in the static electricity generating region are charged with static electricity, when the large amount of ions generated by the ion generating unit 30 meet the objects in the static electricity generating region, the static electricity generated by the objects is attracted by the static electricity on the objects and is neutralized with the static electricity, so that static electricity removal is realized.

In this embodiment, the ion generating device 20 is installed on the body 10 of the vacuum cleaner 00, the ion generating unit 30 in the ion generating device 20 is disposed in the static electricity generating region on the body 10, and the ion generating unit 30 in the ion generating device 20 generates ions, so as to neutralize the static electricity generated during the operation of the vacuum cleaner, and effectively remove the static electricity without depending on the static electricity conducting path, thereby ensuring the overall antistatic property of the body 10.

In the above or following embodiments, during the operation of the vacuum cleaner, objects such as dust, bacteria, etc. may be sucked into the dust suction barrel 60 on the main unit 50 of the vacuum cleaner, and the objects will contact with the moving channel to generate friction during the suction process, and the objects will contact with the barrel wall of the dust suction barrel 60 and generate friction after being sucked into the dust suction barrel 60, so that the surface of the objects sucked into the dust suction barrel 60 carries electrostatic charges, and electrostatic charges may also occur on the barrel wall of the dust suction barrel 60 or other positions in the dust suction barrel 60. Accordingly, the dust suction bucket 60 is a static electricity generation region on the body 10.

In order to remove static electricity in the dust collection tub 60, at least one set of ion generating units 30 may be provided in the dust collection tub 60. The ions generated by the ion generating unit 30 are diffused into the whole barrel cavity of the dust collection barrel 60, and the static charges on the objects in the dust collection barrel 60 and the static charges on the barrel wall and other positions of the dust collection barrel 60 are neutralized when encountering the ions generated by the ion generating unit 30, so that the static charges in the dust collection barrel 60 can be removed. In this embodiment, the static charge generated in the dust collection barrel 60 is removed in time, so as to achieve the antistatic effect in the dust collection barrel 60 region during the operation of the dust collector.

In order to better diffuse the ions generated by the ion generation unit 30 into the entire barrel cavity of the dust collection barrel 60, a boosting force can be provided for the ions generated by the ion generation unit 30. For example, a fan may be disposed at the position where the ion generating unit 30 is disposed, and the orientation of the fan may be determined according to the desired diffusion direction of the ions, and the ions may be more efficiently and more intensively diffused to a desired region by the assistance of the wind force provided by the fan.

As shown in fig. 1b, the main cleaner body 50 is further provided with an air inlet 61, and the air inlet 61 is communicated with the dust collection barrel 60. In this embodiment, at least one set of ion generating units 30 in the dust collection barrel 60 may be distributed on two sides of the air inlet 61. The air inlet 61 of the main body 50 serves as a passage for external dust, bacteria and the like to enter the dust collection barrel 60, and during the operation of the dust collector, the air inlet 61 has an air flow flowing into the barrel cavity of the dust collection barrel 60, and under the boosting force of the air flow, ions generated by the ion generation unit 30 are blown into the dust collection barrel 60, so that the ions can be rapidly diffused into the barrel cavity of the dust collection barrel 60 and neutralize the static charges in the dust collection barrel 60, and therefore, the static electricity removal efficiency can be effectively improved.

Further, the ion generating unit 30 may be further provided in the dust suction extension pipe 80 between the dust suction tub 60 and the dust suction assembly 70. One end accessible air intake 61 of dust absorption extension pipe 80 is connected with dust absorption bucket 60, the other end can communicate dust absorption head 72 in the dust absorption subassembly 70, dust absorption extension pipe 80 becomes the intermediate part of connecting air intake 61 and dust absorption head, the use radius of the expanded dust catcher of extension pipe 80 through the dust absorption, it will pass through dust absorption extension pipe 80 and enter into dust absorption bucket 60 to be inhaled in the dust absorption head in the object, this makes, the motion process of object probably leads to accumulating static in the dust absorption extension pipe 80, in this embodiment, through set up ion generation unit 30 in dust absorption extension pipe 80, can get rid of the static in the dust absorption extension pipe 80.

In the present embodiment, the number of the ion generation units 30 disposed in the static electricity generation region may also be determined according to the number of the static charges in the dust suction bucket 60 in different scenes. For example, if the amount of static charges generated in the dust collection tub 60 is large, two or three ion generating units 30 may be provided in the dust collection tub 60 to generate more ions to neutralize the static charges generated in the dust collection tub 60. The dust collecting extension pipe 80 generates less static electricity and is close to the ground, and part of the static electricity can be conducted to the ground, so that an ion generating unit 30 can be arranged in the dust collecting extension pipe 80 to obtain an ideal antistatic effect.

The ions generated by each set of ion generating units 30 may include cations and anions, the cations can reverse the electrical property of the surface layer of the bacterial protein in two levels to promote bacterial death, so the cations can be used for disinfection, sterilization and the like besides neutralization of static charges; the anion can neutralize static charge, and the anion can purify air, enhance human immunity, and is beneficial to human health. In this embodiment, in order to more fully exert the function of the ions generated by the ion generating unit 30, the ion generating unit 30 may be provided in the air outlet 62 of the cleaner main body 50. It should be noted that the air outlet 62 of the main cleaner 50 can be directly or indirectly communicated with the dust collection barrel 60, which is not limited in this embodiment. The ions generated by the ion generating unit 30 in the air outlet 62 can sterilize and disinfect the air flow passing through the air outlet 62, so that the air flow in the discharged air can be further purified.

In this embodiment, air outlet 62 can be regarded as one section air-out passageway, and in order to further keep apart particulate matters such as the remaining dust in the air current through air outlet 62, still can set up the filter screen in air outlet 62, the particulate matter in the filter screen can effective filtration air current, can select different filter screens to different use scenes, such as HEPA filter screen, ULPA filter screen etc.. In order to avoid the filter screen from blocking the anions from diffusing into the air, in the air outlet 62, the anion generating electrodes and the cation generating electrodes in each group of ion generating units 20 may be distributed on two sides of the filter screen, the anion generating electrodes are close to the outlet end of the air outlet 62, and the cation generating electrodes are far away from the outlet end of the air outlet 62. Therefore, cations generated by the ion generating unit 30 can be retained in the air outlet 62 under the obstruction of the filter screen, so that the air flow of the air outlet 62 can be disinfected, sterilized and the like; the anions generated by the ion generating unit 30 can be smoothly diffused into the air to purify the air, and the anions can enhance the immunity of the human body after entering the respiratory tract of the human body, thereby being beneficial to the health of the human body.

It should be noted that the ion generating unit 30 can generate positive ions and negative ions at the same time, as described above, of course, the ion generating unit 30 can also generate only positive ions and only negative ions, and what kind of ions the ion generating unit 30 needs to generate can be determined according to the usage scenario of the vacuum cleaner, which is not limited in the present invention. For example, the ion generating unit 30 may be configured to generate anions when the static electricity generated by the cleaner in some usage scenarios is all positive. The ion generating unit 30 may be configured to generate positive ions when the static electricity generated by the cleaner is negative in some usage scenarios. Since the electrostatic charge generated in the vacuum cleaner has both positive and negative charges in most usage scenarios, the application range of the ion generating unit 30 for generating both positive and negative ions is wider, and the description of the technical solution will be focused on the ion generating unit 30 for generating both positive and negative ions.

In the above or below embodiments, in order to simultaneously generate cations and anions, the ion generating unit 30 may include an anion generating electrode and a cation generating electrode, and ends of the anion generating electrode and the cation generating electrode have a needle-like structure. In physical implementation, the ion generating unit 30 may be composed of two metal wires, an insulating layer may be disposed outside the metal wires, and ends of the metal wires may be in a needle-like structure. The anion generating electrode is used for generating anions, the cation generating electrode is used for generating cations, and a certain distance is arranged between the anion generating electrode and the cation generating electrode. When high voltage is applied to the anion generating electrode and the cation generating electrode, a strong electric field is generated between the anion generating electrode and the cation generating electrode, corona discharge is generated between the anion generating electrode and the cation generating electrode respectively, air molecules between the anion generating electrode and the cation generating electrode are ionized, a large amount of anions are generated at the end part of the anion generating electrode, and a large amount of cations are generated at the end part of the cation generating electrode. The positive ions and the negative ions are diffused into the static electricity generation area, objects carrying positive charges in the static electricity generation area attract the negative ions to generate static electricity neutralization, and objects carrying negative charges in the static electricity generation area attract the negative ions to generate static electricity neutralization, so that static electricity in the static electricity generation area is removed.

In this embodiment, the ion generating unit 30 can generate a large amount of anions and cations simultaneously, so that even if the static electricity generated during the operation of the vacuum cleaner includes both positive charges and negative charges, the static electricity can be efficiently and completely removed. Of course, for the usage scenario that only a single type of static charge is generated during the operation of the vacuum cleaner, the corresponding type of ions can participate in the static neutralization process in the present embodiment, and the remaining another type of ions can be used for other purposes, for example, the remaining cations can be used for disinfection and sterilization, and the remaining anions can be used for enhancing the immunity of the human body.

In practical applications, the ion generating unit 20 may adopt various circuit structures to generate ions by the ion generating unit 30, and fig. 2a is a schematic structural diagram of the ion generating unit 20 in a vacuum cleaner according to an exemplary embodiment of the present invention. It should be noted that the ion generating device 20 may also adopt other circuit configurations, and the circuit configuration shown in fig. 2a should not be construed as limiting the ion generating device 20 of the present invention.

In the above or following embodiments, in order for the ion generating unit 30 to generate ions, as shown in fig. 2a, the ion generating device 20 may further include: an oscillation circuit 200, a step-up transformer 201, and a high-voltage rectification circuit 202; the oscillation circuit 200 is connected to a step-up transformer 201 via a switching circuit 203, and the step-up transformer 201 is connected to a high-voltage rectification circuit 202. The oscillating circuit 200 is used for controlling the on/off of the switch circuit 203 to generate an oscillating voltage, and the oscillating voltage is boosted by the booster transformer 201, enters the high-voltage rectifying circuit 202, is subjected to voltage doubling rectification, and is output to the ion generating unit 30.

In this embodiment, after the input voltage passes through the oscillating circuit 200, the oscillating circuit 200 outputs a pulse signal, the oscillation frequency of the pulse signal can be adjusted according to practical applications, the pulse signal can be used to control the on/off of the switch circuit 203, and the oscillating circuit 200 can be formed by RC oscillation, transformer feedback LC oscillation, or inductive oscillation. The input voltage is applied to the switching circuit 203 after passing through the primary coil of the step-up transformer 201, and the switching tube in the switching circuit 203 may be a triode, a thyristor or a MOS tube. The oscillating voltage output by the output end of the switch circuit 203 is boosted by the step-up transformer, and then is subjected to voltage doubling rectification by the high-voltage rectification circuit 202 to obtain positive and negative high voltages about ten thousand volts, and the positive and negative high voltages are connected to the ion generating unit 30, so that air is discharged and ionized to form ions, and the ions are neutralized with static electricity generated in the working process of the dust collector, so that the static electricity of the ions is eliminated, and the effect of purifying air can be achieved along with air outlet of the dust collector.

In this embodiment, the positive and negative high voltages generated by the high voltage rectification circuit 202 may be simultaneously applied to the ion generating unit 30, and the ion generating unit 30 may simultaneously generate anions and cations based on the positive and negative high voltages. Of course, the positive or negative high voltage generated by the high voltage rectification circuit 202 may be applied to the ion generating unit 30 alone, and when only the negative high voltage is connected to the ion generating unit 30, anions may be generated, and when only the positive high voltage is connected to the ion generating unit 30, cations may be generated. Therefore, in the present embodiment, the high voltage applied to the ion generating unit 30 can be selected according to the requirements of the usage scenario.

In this embodiment, the input voltage may be provided to the ion generating device in various ways, for example, 220v commercial power may be directly used as a power supply to provide the voltage to the ion generating device 20. However, the power cord is connected to the commercial power supply to obtain the voltage provided by the commercial power supply, which causes inconvenience to the use of the vacuum cleaner.

Fig. 2b is another structural block diagram of an ion generating device in a vacuum cleaner according to an exemplary embodiment of the present invention.

As shown in fig. 2b, in this embodiment, the ion generating device 30 may further include a dc power module 204 and a dc power converting circuit 205; the dc voltage output from the dc power supply module 204 is converted by the dc power supply conversion circuit 205 and then output to the step-up transformer and the oscillation circuit in the ion generation device 20. The dc power conversion circuit 205 converts the current value and the voltage value of the dc voltage output by the dc power module 204 to obtain an input voltage meeting the operation requirement of the ion generating device 20. The operation of the ion generating device 20 after the input voltage is inputted into the step-up transformer 201 and the oscillating circuit 200 can be referred to above, and is not described herein again.

In this embodiment, the dc power module 204 provides power for the ion generating device 20, so that the ion generating device 20 does not need to be connected to an external ac power source through a power line, but uses the dc power module 204 that can be disposed inside the vacuum cleaner to supply power, which not only ensures the normal operation of the ion generating device 20, but also improves the adaptability of the ion generating device 20. In addition, the ion generating process of the ion generating device 20 and the dust collecting process of the dust collector can share the dc power module 204, for example, a battery pack inside the dust collector can be used as the dc power module 204. Therefore, the dust collector can realize static electricity removal while collecting dust without being connected with an external alternating current power supply.

In the above or following embodiments, the main body 10 of the cleaner may further be provided with a controller 102. The controller 102 is electrically connected to the ion generating device 20, and is configured to detect an operating state of the vacuum cleaner, and activate the ion generating device 20 to generate ions and neutralize static electricity in the static electricity generating region when the operating state of the vacuum cleaner meets a static electricity removing condition. Of course, the controller 102 may also control the vacuum cleaner to perform other tasks, such as cleaning, as a control system for the vacuum cleaner. The controller 102 may be implemented by a single chip, or may be implemented by other methods.

In this embodiment, the working state of the dust collector may include, but is not limited to, a power-on state, a power-off state, a state during dust collection, an electrostatic overload state, and the like, where the power-on state refers to a state when the dust collector starts to collect dust, the power-off state refers to a state when the dust collector stops collecting dust, the state during dust collection refers to a state when the dust collector is in a dust collection process, and the electrostatic overload state refers to a state when the electrostatic charge concentration in the dust collector exceeds a preset value. The static electricity removing condition can be preset based on the working state of the dust collector, for example, when the dust collector starts to collect dust, the dust collection time of the dust collector is greater than a first time threshold value, or when the static electricity is overloaded, the static electricity removing condition can be set as the static electricity removing condition.

The controller 102 may periodically detect the working state of the vacuum cleaner automatically or through manual triggering, and determine whether the current working state of the vacuum cleaner meets the static removing condition according to the preset static removing condition, and if so, start the ion generating device 20. When determining that the current working state of the dust collector meets the static electricity removal condition, the controller 102 can control the on/off of the ion generating device 20 by controlling the input voltage of the ion generating device 20. For example, the controller 102 may control the input voltage of the ion generating device 20 by controlling the on/off of the circuit between the dc power supply module 204 and the dc power conversion module in the above embodiments, so as to control the on/off of the ion generating device 20.

Further, in order to achieve better static electricity removing effect, in this embodiment, the ion generating device 20 may further include: several ion sensors, not shown. The ion sensors are arranged in the static electricity generation area and used for detecting ion release concentration and static charge concentration in the static electricity generation area. The controller 102 is also connected with a plurality of ion sensors and is used for adjusting the dust collection air volume of the dust collector according to the ion release concentration and the electrostatic charge concentration detected by the plurality of ion sensors.

The ion sensor can detect the ion release concentration and the static charge concentration in the static electricity generation area where the ion sensor is located, and the ion sensor can be respectively arranged at different positions of the static electricity generation area to detect the ion release concentration and the static charge concentration. For example, when the ion generating unit 30 includes the anion generating electrode and the cation generating electrode of the foregoing embodiments, ion sensors may be provided at the anion generating electrode and the cation generating electrode, respectively, for sensing the anion emission concentration and the cation emission concentration of the ion generating unit 30, respectively; an ion sensor may be further disposed in the dust collection barrel 60 for sensing the amount of static charge in the dust collection barrel 60, and in the present embodiment, the ion sensor is considered to sense the residual amount of static charge after static neutralization in the dust collection barrel 60. Based on the electrostatic charge concentration detected by the ion sensor, that is, the residual electrostatic charge concentration after neutralization of static electricity in the static electricity generation region, the controller 102 may adjust the dust collection air volume of the dust collector, for example, when the electrostatic charge concentration is high, the dust collection air volume of the dust collector may be reduced, and when the electrostatic charge concentration is zero, the dust collection air volume of the dust collector may be increased.

In order to improve the utilization rate of the ions generated by the ion generating device 20, in this embodiment, the controller 102 may further calculate a ratio of the ion release concentration and the electrostatic charge concentration detected by the ion sensor; determining the ion balance state in the static electricity generation area according to the ratio; and adjusting the dust collection air quantity according to the ion balance state in the static electricity generation area. Alternatively, the controller 102 may calculate the ion balance state corresponding to each static electricity generating region, or may directly calculate the ion balance state of the whole vacuum cleaner, which is not limited in this embodiment. Based on the ratio of the ion release concentration to the electrostatic charge concentration corresponding to each ion sensor in the static electricity generation region, the controller may determine the ion equilibrium state in each static electricity generation region by averaging a plurality of ratios, and of course, other rules may be adopted according to actual requirements, and are not limited.

When the ion release concentration is much greater than the electrostatic charge concentration, the ratio of the ion release concentration to the electrostatic charge concentration is much greater than 1, which indicates that the ion amount generated by the ion generating device 20 is far greater than the electrostatic charge amount generated in the electrostatic generating region, and the ion balance state is unbalanced. In this case, it is described that the ion generating device 20 is capable of removing more static electricity, and thus the controller 102 can increase the amount of suction air of the cleaner. Similarly, when the ion emission concentration is smaller than the electrostatic charge concentration, the ratio of the ion emission concentration to the electrostatic charge concentration will be smaller than 1, which indicates that the ion number generated by the ion generating device 20 is already lower than the electrostatic charge number generated in the electrostatic charge generating region, and the ion balance state is unbalanced. In this case, it is described that the ion generating device 20 cannot completely remove static electricity in the vacuum cleaner, and therefore, the controller 102 needs to reduce the amount of air sucked by the vacuum cleaner to reduce the amount of generated static electricity, so as to avoid static electricity accumulation due to incomplete removal of static electricity.

Optionally, the main body 10 further includes a display screen, wherein the ion balance state can be displayed through the display screen on the main body 10 for a user to refer to, and the user can also set the corresponding relationship between the ion balance state and the dust collection air volume adjustment according to the preference. For example, when the ion balance state indicates that the ion release concentration is 2 times of the electrostatic charge concentration, the dust suction air volume can be increased by 0.3 times. Therefore, intelligent control can be better realized, and user experience is improved.

Fig. 3 is a schematic flow chart of an antistatic method according to another exemplary embodiment of the present invention. The method is applicable to a vacuum cleaner, as shown in fig. 3, and comprises the following steps:

300. detecting the working state of the dust collector;

301. determining that the working state of the dust collector meets the static removing condition;

302. activating an ion generating device on the dust collector to generate ions to neutralize static electricity on the dust collector.

In this embodiment, the working state of the vacuum cleaner may include, but is not limited to, a power-on state, a power-off state, a vacuum-in state, an electrostatic overload state, and the like. The starting state refers to the state of the dust collector at the moment of starting dust collection, the shutdown state refers to the state of the dust collector at the moment of stopping dust collection, the state during dust collection refers to the state of the dust collector in the process of dust collection, and the electrostatic overload state refers to the state of the dust collector at the moment when the electrostatic charge concentration exceeds the preset value. The static electricity removing condition can be preset based on the working state of the dust collector, for example, when the dust collector starts to collect dust, the dust collection time of the dust collector is greater than a first time threshold value, or when the static electricity is overloaded, the static electricity removing condition can be set as the static electricity removing condition.

In this embodiment, the working state of the vacuum cleaner can be detected periodically and automatically or by manual triggering, and whether the current working state of the vacuum cleaner meets the static removing condition is judged according to the preset static removing condition, if yes, the ion generating device is started. When the current working state of the dust collector is determined to meet the static electricity removing condition, the on-off of the ion generating device can be controlled by controlling the input voltage of the ion generating device. For example, the control of the presence or absence of the input voltage of the ion generating device can be realized by controlling the on/off of the circuit between the dc power supply module and the dc power supply conversion module in the above embodiment, so as to control the on/off of the ion generating device.

In the above or following embodiments, it may be determined that the operating condition of the cleaner meets the static discharge condition at least in the following manner:

when the dust collector starts to collect dust, determining that the working state of the dust collector meets the static electricity removing condition; alternatively, the first and second electrodes may be,

and when the dust collection duration of the dust collector is greater than the first duration threshold value, determining that the working state of the dust collector meets the static removing condition.

That is, the ion generating device may be activated at the time when the cleaner starts to suck dust, or may be activated when the cleaner continues to suck dust for more than the first time threshold after the cleaner starts to suck dust. After the dust collector starts to collect dust, objects such as dust, bacteria and the like are sucked into the dust collector, static electricity is generated, and therefore the ion generating device can be synchronously started at the moment when the dust collector starts to collect dust. Of course, since the dust collector generates less static electricity after starting to collect dust, the ion generating device can be turned on after the dust collector continuously collects dust for a certain time.

Of course, the working state of the dust collector can be determined to meet the static electricity removing condition in other ways. For example, the ion generating device may be activated when the electrostatic charge concentration in the static electricity generating region exceeds a preset value. Embodiments of the invention are not limited in this respect.

In the above or following embodiments, after the ion generating device on the dust collector is started, the working state of the dust collector can be continuously detected, and whether the action state of the dust collector meets the static electricity removing condition or not can be judged; and turning off the ion generating device when the working state of the dust collector is determined to be no longer in accordance with the static electricity removing condition. This is advantageous to avoid inefficient operation of the ion generating device.

In this embodiment, the determining that the working state of the vacuum cleaner no longer meets the static eliminating condition at least in the following manner includes:

when the dust collector stops collecting dust, determining that the working state of the dust collector does not accord with the static removing condition any more; alternatively, the first and second electrodes may be,

and when the time length of the dust collector after stopping dust collection is greater than the second time length threshold value, determining that the working state of the dust collector does not accord with the static electricity removing condition any more.

That is, the ion generating device may be turned off at the time when the cleaner stops cleaning, or may be turned off when the cleaner continues to maintain the cleaning-stopped state after the cleaning is stopped and exceeds the second time threshold. After the dust collector stops sucking dust, static electricity is not generated any more, so that the ion generating device can be synchronously closed at the moment when the dust collector stops sucking dust. Since a part of residual static electricity may not be removed after the dust collector stops sucking dust, and the part of static electricity may still cause damage to parts of the dust collector or human bodies, the ion generating device can be turned off when the dust collector continuously keeps a dust-stopping state for more than a second time threshold.

Of course, it can be determined in other ways that the working state of the cleaner no longer meets the static electricity removing condition. For example, the ion generating device may be turned off when the electrostatic charge concentration in the static electricity generating region is less than a preset value. Embodiments of the invention are not limited in this respect.

In the above or below embodiments, in order to achieve better static electricity removal effect, the ion release concentration and the static charge concentration detected by the ion sensor on the ion generating device in the static electricity generating area where the ion sensor is located can also be obtained; and adjusting the dust collection air quantity of the dust collector according to the ion release concentration and the electrostatic charge concentration detected by the ion sensor.

The static electricity generating area is an area where static electricity is generated during the operation of the dust collector, that is, an area where the static electricity needs to be removed. In different scenes, the static electricity generating area can be different, for example, the static electricity generating area can be a dust suction barrel of the dust collector, an air inlet connected with the dust suction barrel, and other areas on the dust collector.

Further optionally, where the ion generating device comprises a number of ion sensors, the number of ion sensors may detect ion release concentration and electrostatic charge concentration within the static electricity generating region. Ion sensors may be provided at different positions of the static electricity generation region, respectively, to detect the ion discharge concentration and the static charge concentration. For example, when the ion generating unit includes the anion generating electrode and the cation generating electrode of the foregoing embodiments, the anion emission concentration and the cation emission concentration of the ion generating unit can be sensed by the ion sensors respectively provided on the anion generating electrode and the cation generating electrode; the amount of static charge in the dust collection bucket 60 can also be sensed by an ion sensor arranged in the dust collection bucket of the dust collector, and the ion sensor is considered to sense the residual amount of static charge after static neutralization in the dust collection bucket in the embodiment.

In this embodiment, the dust collection air volume of the dust collector can be adjusted based on the electrostatic charge concentration detected by the ion sensor, that is, the residual electrostatic charge concentration after the static neutralization in the static electricity generation region. When the concentration of the static charge is larger, the dust collection air volume of the dust collector can be reduced, and when the concentration of the static charge is zero, the dust collection air volume of the dust collector can be increased.

In order to improve the utilization rate of the ions generated by the ion generating device, in this embodiment, the ratio of the ion release concentration and the electrostatic charge concentration detected by the ion sensor can also be calculated; determining the ion balance state in the static electricity generation area according to the ratio; and adjusting the dust collection air quantity according to the ion balance state in the static electricity generation area. In this embodiment, the ion balance state corresponding to each static electricity generation region may be calculated separately, or the ion balance state of the whole vacuum cleaner may be calculated directly, which is not limited in this embodiment. Based on the ratio of the ion release concentration and the electrostatic charge concentration corresponding to each ion sensor in the static electricity generation region, the ion balance state in each static electricity generation region can be determined by averaging a plurality of ratios, and of course, other rules can be adopted according to actual requirements, and the method is not limited.

When the ion release concentration is far greater than the electrostatic charge concentration, the ratio of the ion release concentration to the electrostatic charge concentration is far greater than 1, which indicates that the ion quantity generated by the ion generating device is far greater than the electrostatic charge quantity generated in the electrostatic generating area, and the ion balance state is unbalanced. In this case, the ion generating device is capable of removing more static electricity, and therefore, the suction air volume of the vacuum cleaner can be increased. Similarly, when the ion release concentration is less than the electrostatic charge concentration, the ratio of the ion release concentration to the electrostatic charge concentration will be less than 1, which indicates that the ion number generated by the ion generating device is already lower than the electrostatic charge number generated in the electrostatic generating region, and the ion balance state is unbalanced. In this case, it is described that the ion generating device cannot completely remove static electricity in the vacuum cleaner, and therefore, it is necessary to reduce the amount of air sucked by the vacuum cleaner to reduce the amount of generated static electricity, thereby preventing static electricity from accumulating due to incomplete removal of static electricity.

Optionally, the ion balance state can be displayed through a display screen on the machine body for a user to refer to, and the user can set the corresponding relation between the ion balance state and the dust collection air volume adjustment according to the preference. For example, when the ion equilibrium state characteristic ion release concentration is 2 times of the static charge concentration, the dust suction air quantity can be increased by 0.3 times. Therefore, intelligent control can be better realized, and user experience is improved.
