Abstract

An electric dust collector with high-frequency high-voltage generator is composed of a case 1, an emitter wire 2, a bottom board 3, an anode plate 4, a dust collecting paper 5 and a high-voltage generator 6. The utility model is characterized in that the electric dusat collector with high-frequency high-voltage generator has the high-frequency oscillation circuit composed of a diode D-[1], a high-frequency element triode BG, a resister R-[1], R-[2] and a capacitance C-[2] and the high-voltage circuit composed of a high-frequency transformer B and a diode D-[2], D-[3]. Compared with the prior art, because of making no use of a low-frequency transformer, but adopting a high-frequency element to simplify the high-voltage generator greatly, the utility model has the advantages of simple structure, low cost, small size and light weight. Because of adopting the means of high frequency oscillation, the utility model improves the conversion efficiency of energy, without the limit of the quantity of the element.

Description

Electric dust collector with high-frequency high-voltage generator

The utility model relates to high-pressure static cleaner.

" air is in harmonious proportion in Japan

Freezing " 12 phases in 1985 introduced a kind of novel ultra-thin type noiselessness electrical air deduster, it can be with the following particulate dust adsorption filtration of several microns in the air, the rejection rate height, easy to use, because having adopted a kind of segmentation multiplication of voltage boosting mode and ultrathin transformer to produce positive and negative 8000 volts of voltages is added in respectively on cathode line and the positive plate, form the high-pressure electrostatic electric field, utilize electric field force that dust in air is adsorbed, its shortcoming is that the components and parts cost is higher, the structure relative complex, because through multistage power conversion is bigger energy loss, operating efficiency is not very good.

The utility model is the shortcoming that overcomes above-mentioned multistage voltage-multiplying type step-up method, has adopted high-frequency electronic vibration to produce the high-frequency and high-voltage mode, makes the designs simplification of high pressure generator to have reduced cost, improves power conversion usefulness.

Description of drawings: Fig. 1 is the electronic dust catcher structural representation that has high-frequency and high-voltage generator, and Fig. 2 is the high pressure generator fundamental diagram of this electronic dust catcher.

Narrate the structure of this electronic dust catcher below in conjunction with Fig. 1, it is to be made and had the shell 1 that the space can allow air milli unit enter with hindering by translucent plastic, be installed in the cathode line 2 on the base plate 3 or on the shell 1, positive plate 4 is equipped with in its front of base plate 3, high pressure generator 6 is equipped with at the back side, make and be installed in positive plate 4 on the base plate 3 by two sheet metals, be installed between cathode line 2 and the positive plate 4 and be covered in control of dust paper 5 on the positive plate 4, and the high pressure generator 6 that is installed in base plate 3 back sides constitutes.

The operation principle of the high pressure generator of this electronic dust catcher is as shown in Figure 2: 220 volts of AC powers are rectified into direct current through diode DI, supply high frequency triode BG and resistance R ₁, R ₂Capacitor C ₂Form high-frequency oscillating circuits, produce high frequency voltage, after high frequency transformer B is increased to voltage two-way 9000-10000 volt, again through diode D ₂, D ₃Rectification becomes high voltage direct current, adds to respectively on cathode line 2 and the positive plate 4; The positive and negative 9000 volts of high pressure that produced by high pressure generator 6, between cathode line 2 and positive plate 4, form a high-pressure electrostatic electric field, because 18000 volts potential difference produces corona discharge on cathode line 2, make a large amount of electronics from negative electrode upper edge power line direction to around emit.Because the electronics emission rate is very fast, causes near the atomic ionization the cathode line 2, thereby form a large amount of anion; Anion is attracted by anode, and a part is moved towards positive plate along the power line direction, simultaneously with ionization in the air molecule together move, form ion wind; Another part anion then flies in the air along the power line direction, make airborne molecular anionization, make dirt particle all be with (one), these have (one) electricity particulate and positive plate between exist certain electric field force, these particulates slowly move to dust arrester along the power line direction with airborne anion under the effect of electric field force, be subjected to the ion wind effect in the time of near arriving dust arrester and be inhaled in the housing, adhere on the control of dust paper 5 that covers positive plate 4 surperficial static electrifications.

The utility model compared with the prior art its advantage is:

1, owing to adopt the high frequency components and parts that high pressure generator is simplified, simple in structure, cost only is about 1/5th of segmentation voltage-multiplying type electronic dust catcher;

2, owing to, adopted high-frequency component, the volume and weight of dust arrester is greatly reduced without low-frequency transformer;

3, owing to adopt higher-order of oscillation method, not limited by component number, it is higher to produce the high pressure conversion efficiency, and voltage can improve about 10-20% under identical power conditions.

The utility model is a kind of senior health care electronic apparatus; the place that can be used for people's daily routines such as family, hospital, office, shop, hotel, restaurant; specially to dedusting and purifying air; eliminate peculiar smell; because can produce a large amount of anions human body there is excellent health functions simultaneously; make blood purification, cell activation, enhancing dysfunction of nervous regulation etc. has obtained generally acknowledged in medical circle.For the laboratory of the ultrapurification workplace that requires the noiselessness dust-free sterile, food processing factory, making sheet chamber, printing house, semiconductor factory, chemical plant, pharmaceutical factory etc. all can use this product.
