The maintenance structure of the ionizer according to the embodiment of the present invention will be described below with reference to the accompanying drawings. The ion generator is provided with at least one pair of high-voltage discharge ends, and the maintenance structure comprises a driving part and a contact part, wherein the driving part is connected with the contact part and is used for driving the contact part to rotate; the contact portion is used for contacting the high-voltage discharge end surface in the process of rotating movement, so that pollutants on the high-voltage discharge end surface are removed and electric charges are accumulated.
The ionizer in this embodiment may be a positive/negative ion generator, a negative ion generator, or a plasma generator, and when the ionizer is a positive/negative ion generator or a plasma generator, the ionizer may only include a pair of high-voltage discharge ends, i.e., a positive high-voltage discharge end and a negative high-voltage discharge end, or may include a plurality of pairs of high-voltage discharge ends.
The specific form of the high-voltage discharge end is not limited in this embodiment, and alternatively, the high-voltage discharge end is a tip in the form of a probe, and generally includes a cylindrical body and a tip located on one top surface of the cylinder. In other embodiments of the present application, the high voltage discharge end may also be in the form of a carbon brush formed by a soft brush.
In this embodiment, the driving portion may be disposed on some components inside the ionizer, or may be separately disposed inside the ionizer; the contact part is arranged corresponding to the high-voltage discharge end, and the specific contact part is positioned on the tip of the high-voltage discharge end. The contact part has different forms aiming at different forms of high-voltage discharge ends, and can be flexibly arranged by a person skilled in the art.
The contact portion is adapted to be able to contact the high-voltage discharge end surface during the rotational movement. When the ionizer has only one pair of high-voltage discharge ends, the contact portion may be provided to be able to contact the pair of high-voltage discharge ends simultaneously during the rotational movement. When the ionizer has a plurality of pairs of high-voltage discharge ends, then the contact portion may be provided so as to be able to contact the plurality of pairs of high-voltage discharge ends cyclically during the rotational movement.
The contact part serves on the one hand to eliminate contamination of the high-voltage discharge end surface. Specifically, the method comprises the following steps: the contact part passes through the surface of the high-voltage discharge end for many times in the process of rotating, so that the wiping effect is achieved, and pollutants are removed through friction. The contact portion on the other hand serves to eliminate accumulated charges on the surface of the high-voltage discharge end. Specifically, the method comprises the following steps: the contact part contacts the paired high-voltage discharge ends in the rotating process, and accumulated charges of the high-voltage discharge ends are transferred to the contact part, so that positive and negative charges accumulated by the paired high-voltage discharge ends are eliminated.
The maintenance structure of the ion generator in the embodiment of the invention is beneficial to reducing the attenuation of the ionization effect of the ion generator, is beneficial to the continuous and normal work of the ion generator, and has the advantages of simple and convenient structure, easy realization and the like.
The maintenance structure can further comprise a fixed supporting plate which is fixedly connected with the ion generator. The driving part can comprise a motor cabin, a motor and a rotating bracket. Wherein, motor storehouse and fixed support plate fixed connection, the motor is fixed in the motor storehouse, runing rest and motor's pivot fixed connection.
The motor is preferably a stepper motor. Because the torque of the stepping motor is high and the rotating speed is low, the rotating shaft of the stepping motor stops moving immediately under the condition of stopping the power supply input, and cannot rotate continuously due to inertia. The maintenance structure adopting the stepping motor has the advantage of highly controllable movement process.
The maintenance structure in this embodiment further includes a circuit module for controlling the start and stop of the motor, and the circuit module may be located on the fixed support plate and electrically connected to the motor. The printed circuit board can be directly employed to serve as both the fixed support plate and the circuit module. The circuit module can be flexibly provided with a manual switch unit and/or an automatic switch unit to control the starting and stopping of the motor, so that the starting and stopping of the maintenance operation are controlled.
The maintenance structure may further comprise a rotational counting mechanism for monitoring the cumulative number of revolutions of the rotational movement. The circuit module is electrically connected with the rotation counting module and can control the motor to stop when the accumulated rotation number provided by the rotation counting mechanism reaches a preset threshold value. The motor stops after rotating for enough circles, which means that the contact part does not rotate any more, the maintenance operation is finished, and the intelligent motor has the advantages of no need of user operation and intellectualization.
The rotary counting mechanism specifically comprises a magnet and a Hall device, wherein the magnet is fixed at the non-rotary center position of a rotary arm of the rotary support; the hall device is fixed in a position near a locus of a rotational movement of the magnet, and senses a magnetic field of the magnet and generates a signal. The "nearby position" here means a position where the change in the magnetic field due to the movement of the magnet can be effectively sensed.
The contact portion may include a pair of brush heads fixed to both ends of a radial arm of the rotating bracket. The brush head is static and has a safe distance with a pair of high-voltage discharging ends in a first state (namely, in a power-off stop state), and rotates and can contact the pair of high-voltage discharging ends in a moving process in a second state (namely, in a power-on working state).
The brush heads may be made of an electrically conductive material and electrically connected to each other. The conductive material may be metal or other materials such as conductive rubber.
When the number of the brush heads is one pair and the number of the high-voltage discharge ends is one pair, in the first state of the brush heads, a connecting line between the pair of brush heads and a connecting line between the pair of high-voltage discharge ends can have an included angle of a certain degree, and the included angle is preferably 90 degrees. Therefore, the distance between the brush head and the high-voltage discharge end is larger, and the normal release of ions from the high-voltage discharge end is not influenced.
An ionizer according to an embodiment of the present invention has at least one pair of high-voltage discharge ends, and a maintenance structure according to any one of the embodiments of the present invention is provided in the ionizer. The ionizer may also generally include a bottom case and a top cover. The bottom shell is fixedly connected with the fixed supporting plate, and the top cover is fixedly connected with the bottom shell. The bottom shell and the top cover form a cavity after being installed and combined, and the cavity is used for accommodating at least part of parts of the maintenance structure.
An electrical appliance according to an embodiment of the present invention includes an ionizer according to an embodiment of the present invention.
In order to make the skilled person better understand, the following describes the specific structure of the ionizer in accordance with the embodiment of the present invention with reference to fig. 2 to 7.
Fig. 2 to 7 show a maintenance structure of the ionizer according to the embodiment of the present invention. The ion generator has a bottom shell 18 and a top cover 19 which are matched and combined, a pair of high-voltage discharge ends 11 are arranged above the bottom shell 18, and a protective cover 17 is arranged on the periphery of the high-voltage discharge ends 11. The maintenance structure comprises a fixed support plate 12, a motor bin 13, a motor 14, a rotating bracket 15, a pair of brush heads 16, and a circuit module which is not shown in the figure. The rotating motion track of the pair of brush heads 16 passes through the position of the pair of high-voltage discharge ends 11.
The working process of the maintenance structure of the ion generator is as follows: after the motor 14 is powered on, the rotating shaft rotates to drive the rotating support 15 to rotate, and the rotating support 15 rotates to drive the brush head 16 to rotate, so that the brush head 16 rubs the surface of the high-voltage discharge end 11 when passing through the high-voltage discharge end 11, and pollutants on the surface of the high-voltage discharge end 11 can be removed. In addition, if the brush heads 16 are metal brush heads and are electrically connected to each other, the positive and negative charges accumulated on the surfaces of the pair of high-voltage discharge ends 11 are transferred to the pair of brush heads 16. The pair of brush heads 16 are electrically connected to each other by means of wires or the like, so that the electric charges on the pair of brush heads 16 are eliminated.
As shown in fig. 6, when the pair of brush heads 16 is in the first state (i.e. when the rotating bracket 15 is not powered on and is stationary), the angle between the line between the pair of brush heads 16 and the line between the pair of high-voltage discharging ends 11 is 90 °.
As shown in fig. 7, the swing arm of the swing frame 15 is provided with a magnet 20 in addition to the brush head 16. When the motor 14 rotates the rotating bracket 15, the magnet 20 rotates therewith. A hall device (not shown in the drawings) may be provided inside the bottom case 18 in the vicinity of the locus of the rotational movement of the magnet 20. The magnet 20 and the hall device constitute a rotary counting mechanism. The working process of the maintenance structure with the rotary counting mechanism is as follows: when maintenance work is performed, the rotating bracket 15 drives the brush head 16 and the magnet 20 to rotate. When the magnet 20 rotates for a plurality of circles along with the rotating bracket 15, the hall device fixed near the rotating motion track of the magnet 20 induces the periodic change of the magnetic field so as to induce a plurality of periodic electrical signals; the electric signal is subjected to analog-to-digital conversion by the circuit module, so that the circuit module obtains the accumulated number of rotations; when the accumulated number of rotations reaches a preset threshold, the circuit module controls the motor 14 to be powered off and stopped, and then the maintenance operation is stopped.
The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
