Description

Self-cleaning plasma purifier

Technical Field

The present disclosure relates to the field of plasma technology, and in particular, to a self-cleaning plasma purifier.

Background

At present, a front-edge air purifying device generally adopts a plasma generator to purify air. The plasma purification technology utilizes high-voltage discharge to ionize air to generate a large amount of electrons and ions, and the instant high energy generated by mutual collision and annihilation of the positive and negative ions can kill microorganisms in the air, so that the effects of sterilization and disinfection are achieved. At the same time, a large amount of free radicals such as OH, O and the like which are excited in the discharging process can be further mixed with formaldehyde and SO ₂ 、NO ₂ And TVOC organic molecules and other pollutants react to decompose the pollutants. In addition, particles with different numbers of charges are mutually attracted due to the adsorption of positive and negative ions in the air, and the particles can be changed from small particle size to larger particle size, so that the dust settling effect is achieved.

However, the conventional plasma air purification technology has high sterilization efficiency, but dust is easily accumulated on the plasma generating electrode after long-term operation, so that the ion release efficiency of the plasma generating electrode is greatly reduced, and the air purification capability is also reduced. The timed manual cleaning of the plasma generating electrode requires the disassembly of the air purifier, and has complex operation and inconvenient cleaning.

negative ion emitters

31a, 31b, 31c, 31d, etc.) for emitting negative ions.

The cleaning mechanism 40 is provided on the base 10, and can be used to clean the positive ion releaser (e.g., positive ion releaser 21a, positive ion releaser 21b, positive ion releaser 21c, positive ion releaser 21 d) and the negative ion releaser (e.g., negative ion releaser 31a, negative ion releaser 31b, negative ion releaser 31c, negative ion releaser 31 d). The socket 50 is detachably connected to the base 10 for supplying power to the positive ion emitter array 20 and the negative ion emitter array 30.

As shown in fig. 1 and 2, the base 10 is a flat rectangular parallelepiped, and the positive ion emitter array 20 and the negative ion emitter array 30 are disposed on the base 10 side by side. A cleaning mechanism 40 is disposed on the base 10 between the positive ion emitter array 20 and the negative ion emitter array 30. As shown in fig. 1 and 2, the base 10 may include a body formed by pouring glue, and the potting glue from which the base 10 is made may include epoxy, silicone, polyurethane, and the like.

It will be appreciated by those skilled in the art that although the base 10 is shown in fig. 1 and 2 as a flat rectangular parallelepiped, the base 10 may be at least one of oval cylindrical, prismatic, etc.

As shown in fig. 1, in some embodiments of the present disclosure, the self-cleaning plasma purifier 100 may further include a blower 60 and a housing 70. The fan 60 can be used to drive the airflow through the positive ion emitter array 20 and the negative ion emitter array 30. The housing 70 may include an air inlet and an air outlet.

As shown in fig. 1-3, in some embodiments of the present disclosure, the cleaning mechanism 40 may include a motor 42 and a cleaning member 41. The cleaning member 41 is connected to an output end of the motor and is operable to be moved by the motor 42 to clean the positive ion emitter array 20 and the negative ion emitter array 30. In some embodiments of the present disclosure, the cleaning member 41 can be configured to rotate under the driving of the motor 42, and the cleaning member 41 can complete one cleaning of the positive ion emitter array 20 and the negative ion emitter array 30 as the motor 42 rotates one revolution. The cleaning mode mainly comprises that the tips of the positive ion releaser array 20 and the negative ion releaser array 30 are shifted to clean dust and other attached impurities above, so that the positive ion releaser array 20 and the negative ion releaser array 30 keep ion releasing capacity to ensure plasma concentration in the whole environment. The single cleaning member 41 can avoid the problem of reduced efficiency of plasma generation caused by simultaneous contact with all of the positive ion emitter arrays 20 and the negative ion emitter arrays 30, so that the plasma in the environment is always maintained at a high concentration. The cleaning member 41 may take various suitable forms, such as a cleaning lever, a cleaning sheet, a cleaning brush, and the like.

The partition plate 80 is arranged between the positive ion releaser array 20 and the negative ion releaser array 30, so that annihilation between positive and negative ions can be effectively prevented, the ion concentration in the environment is ensured, meanwhile, the formation of a passage from fibers falling off from fiber clusters of the positive ion releaser array 20 and the negative ion releaser array 30 can be prevented, damage is caused to the whole device, and in addition, a certain voltage effect between the positive and negative releasers can be regulated.

In some embodiments of the present disclosure, the positive ion releaser (e.g., positive ion releaser 21a, positive ion releaser 21b, positive ion releaser 21c, positive ion releaser 21d, etc.) and the negative ion releaser (e.g., negative ion releaser 31a, negative ion releaser 31b, negative ion releaser 31c, negative ion releaser 31d, etc.) may comprise micro-nano conductive fiber clusters comprising at least one of the following: 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-nanofibers in an amount in the range of 1000-100000; or micro-nanofibers having a diameter in the range of 10 nanometers to 100 micrometers. The micro-nano conductive fiber sheets prepared from different numbers of conductive fibers have different surface densities, the larger the number of the fibers is, the smaller the diameter of the conductive fibers is, the shorter the length is, the more the conductive fiber ends in unit area are, the more discharge tips are on a plane, and the higher the plasma emission efficiency is.

In some embodiments of the present disclosure, the self-cleaning plasma purifier 100 may further include a power supply 90 that can be used to power the socket 50 to power micro-nano conductive fiber clusters of positive ion emitters (e.g., positive ion emitter 21a, positive ion emitter 21b, positive ion emitter 21c, positive ion emitter 21d, etc.) and negative ion emitters (e.g., negative ion emitter 31a, negative ion emitter 31b, negative ion emitter 31c, negative ion emitter 31d, etc.) to the positive ion emitter array 20 and the negative ion emitter array 30, by a large number of fiber discharges, a sufficient discharge path can be ensured to stably emit high concentration plasma. The power supply 90 may include a transformer through which a normal voltage is converted to a high voltage to supply power to the positive ion emitter array 20 and the negative ion emitter array 30.

As shown in fig. 1-3, in some embodiments of the present disclosure, the self-cleaning plasma purifier 100 may further include a controller 101. The controller 101 is used to control the cleaning mechanism 40 to clean the positive ion emitter array 20 and the negative ion emitter array 30. For example, the controller 101 is used to activate the cleaning mechanism 40 to clean the positive ion emitter array 20 and the negative ion emitter array 30 for a predetermined time.

As shown in fig. 3, in some embodiments of the present disclosure, the controller 101 may include a time delay relay that can be used to switch the cleaning mechanism 40 on and off in response to the powering up of the self-cleaning plasma device 100. For example, the controller 101 can periodically activate the cleaning mechanism 40 to clean the positive ion emitter array 20 and the negative ion emitter array 30, and after a predetermined time, deactivate the cleaning mechanism 40. Alternatively, the controller 101 can activate the cleaning mechanism 40 to clean the positive ion emitter array 20 and the negative ion emitter array 30 for a predetermined time upon power-up of the self-cleaning plasma generating apparatus 100. In some embodiments of the present disclosure, the controller 101 may include a time delay relay that can be used to switch the cleaning mechanism 40 on and off in response to power up of the self-cleaning plasma-generating device 100. The controller 101 has a time delay control function to automatically clean the positive ion emitter array 20 and the negative ion emitter array 30 each time the self-cleaning plasma generating apparatus 100 is powered on, and to automatically stop after a predetermined cleaning time has been reached.

Those skilled in the art will appreciate that the predetermined time may be adjusted as desired. The intermittent cleaning can effectively achieve the cleaning effect on the positive ion releaser array 20 and the negative ion releaser array 30, avoid the excessive damage on the positive ion releaser array 20 and the negative ion releaser array 30 when continuously cleaned, and prolong the service life of the self-cleaning plasma generating device 100. In addition, when the self-cleaning plasma generating apparatus 100 is powered on, the cleaning mechanism 40 is started to clean the positive ion emitter array 20 and the negative ion emitter array 30, the operation is simple and easy to control, and the manufacturing cost of the self-cleaning plasma generating apparatus 100 can be effectively reduced.

In some embodiments of the present disclosure, the controller 101 is fixedly disposed within the body. When the base 10 is manufactured by glue filling, the controller 101 can be directly packaged in the main body, so that the sealing effect is achieved, and the service life of the controller 101 can be effectively prolonged.

Those skilled in the art will appreciate that while the controller 101 in this disclosure is packaged within the base 10, this is merely an exemplary configuration and that the controller 101 may be mounted on the base 10 or electrically connected to the motor 42 independently of the base 10.

In some embodiments of the present disclosure, the input voltage and current first pass through the controller 101, and then the start and stop of the motor 42 is controlled by the controller 101. The controller 101 may start the motor 42 to rotate so that the cleaning member 41 makes a rotational motion, and after a predetermined time, the controller 101 may stop the power supply to the motor 42 so that the cleaning is stopped. The cleaning member 41 can clean the positive ion emitter array 20 and the negative ion emitter array 30 once every rotation, and the cleaning mode is mainly to stir the tips of the positive ion emitter array 20 and the negative ion emitter array 30 so as to clean attached impurities such as dust above, so that the positive ion emitter array 20 and the negative ion emitter array 30 maintain ion emitting capability, and the ion concentration in the whole environment is ensured. The cleaning mechanism 40 is controlled by the controller 101 to automatically clean the positive ion releaser array 20 and the negative ion releaser array 30, so that the cleaning is free from manual operation, the motor 42 can be cleaned regularly, and the motor does not need to be operated all the time, thereby reducing energy consumption and prolonging the service life of equipment.

It should be noted that the foregoing is merely exemplary embodiments of the present disclosure and are not intended to limit the present disclosure, and any modifications, equivalents, improvements, etc. that fall within the spirit and principles of the present disclosure are intended to be included within the scope of the present disclosure.
