Technical Field

The present invention relates to the field of ionizers, and in particular, to an ionizer and an ion generating component.

Background

Oxygen in the air captures electrons and produces negatively charged anions. The negative ions not only have remarkable effect on purifying air, but also are very beneficial to human health. The content of negative ions in air is highly valued by people, and the concentration of negative ions in air also begins to become an index for judging air quality. High negative ion content of air is increasingly sought.

The natural phenomena in nature such as lightning, sunlight irradiation and photosynthesis can generate negative ions, but the survival time of the generated negative ions is limited, so that the content of the negative ions is insufficient in urban environments such as dense crowds or closed spaces, and the negative ions are not beneficial to human health. Scientists have studied artificial negative ion generation methods from the last century in order to increase the content of negative ions in air, and have come to light with negative ion generators made of high-voltage output power supplies. The negative ion generator simulates the lightning phenomenon in the nature by utilizing a corona discharge mechanism, can generate a large amount of negative ions, effectively improves the content of the negative ions in the air, and is widely used in various air purifiers, air conditioners and other equipment.

The ion generating component is an important component of the ion generator, and as shown in fig. 1, the ion generating component is a schematic structural diagram of a conventional ion generating component, and includes an insulating substrate 41, a ground electrode 42, an emitter electrode 43, an emitter electrode connection end 43d, a first connection port 42b, and a second connection port 43 b.

The ground electrode 42 is disposed on the surface of the insulating substrate 41, and the emitter electrode 43 is cut out of a piano wire or a stainless steel wire and then soldered to the emitter electrode connection terminal 43d in the middle of the insulating substrate 41. The ground electrode is provided at its root portion with a first wiring port 42b, and the first wiring port 42b is used for electrically connecting the ground electrode 42 with the output ground of the ionizer power supply. The root portion of the emitter electrode 43 is provided with a second wiring port 43b, and the second wiring port 43b is used for electrically connecting the emitter electrode 43 with the negative output terminal of the ionizer power supply.

The working principle of the prior art is as follows:

the zero potential end of the high-voltage switch power supply is connected with the first wiring port 42b, the negative output end of the high-voltage switch power supply is connected with the second wiring port 43b, so that a strong electric field can be formed between the grounding electrode 42 and the emitting electrode 43, the field intensity of the front end of the emitting electrode 43 is strongest according to the point discharge theory, a corona discharge phenomenon can be formed at the front end of the emitting electrode 43, and a large amount of electrons are generated at the front end of the emitting electrode 43 and combined with air to form a large amount of negative ions. The smaller the diameter of the emitter electrode 43, the more the effect of the tip discharge is made, and the larger the amount of negative ions can be produced.

The problems existing in the prior art are that: the emitter electrode 43 is cut from a piano wire or a stainless steel wire, and is assembled to the insulating substrate 41, which is inconvenient to assemble. Meanwhile, the smaller the diameter of the emitter electrode 45, the more difficult the assembly. The process limitation of the assembly of the emitter electrode 43 cannot be made so fine, and the point discharge of the linear electrode 43 is directly affected, resulting in the reduction of the content of the negative ion generation. In addition, the emitter electrode 43 is fixed to the insulating substrate 41 only through the second connection port 43b, and there is no extra load-bearing fixing, so that it is difficult and easy to tilt the emitter electrode 43, and once the emitter electrode 43 is tilted, the spatial structure relationship with the ground electrode 42 is affected, thereby affecting the generation of negative ions. In addition, the emitter electrode 43 itself is thin and brittle, and is easily broken by an external force, and the reliability of the ion generating component as a whole is not high.

Detailed Description

First embodiment

Referring to fig. 2-4, the ionizer includes a power source 101, a first connecting line 102, a second connecting line 103, and an ion generating device 104.

The power supply 101 is connected to the ion generating means 104 via a first connection line 102 and a second connection line 103,

the power supply 101 is used to output a negative high voltage.

The ion generating device 104 includes an ion generating component and a housing.

The ion generating component includes a carrier substrate 41, and a ground electrode 42, a first wiring port 42b, an emitter electrode 43, and a second wiring port 43b, which are press-fitted and integrated with the carrier substrate 41.

The carrier substrate 41 is an insulated PCB substrate, the carrier substrate 41 includes a front end portion and a rear end portion, the front end portion is provided with a left protruding portion 41b, a right protruding portion 41c and a protruding portion 41a located between the left protruding portion 41b and the right protruding portion 41c, a first groove 41d is formed between the left protruding portion 41b and the protruding portion 41a, and a second groove 41f is formed between the right protruding portion 41c and the protruding portion 41 a.

The top surface of the boss 41a is press-fitted with the emitter electrode 43, and the root of the emitter electrode 43 is connected to the second wiring port 43 b; a U-shaped ground electrode 42 is press-fitted to the top surfaces of the left and right protrusions 41b and 41c, and has a U-shaped side parallel to and in the same plane as the emitter electrode 43, wherein the distal end of the U-shaped side of the ground electrode 42 is disposed on the top surfaces of the left and right protrusions 41b and 41c, and the root of the ground electrode 42 is connected to the first wiring port 42 b. The grounding electrode 42 and the emission electrode 43 are printed on a PCB, and the surfaces of the grounding electrode 42 and the emission electrode 43 are respectively plated with a tin layer or a gold layer or coated with magnetic powder for protection, so that the grounding electrode 42 and the emission electrode 43 are prevented from being oxidized due to direct contact with air, and the ion generation effect is prevented from being influenced.

The housing is provided with an accommodating cavity 40 and buckles 46a and 46b, wherein the left side and the right side of the inner wall of the accommodating cavity 40 are respectively provided with a clamping groove 45a and a clamping groove 45 b. In this embodiment, the accommodating cavity 40 includes a front cavity and a rear cavity, the front cavity is higher than the rear cavity, and the slots 45a and 45b extend from the front cavity to the rear cavity, wherein the slots 45a and 45b located in the front cavity are disposed in the middle of the front cavity. The catches 46a and 46b are provided on the side wall of the rear end portion of the housing, and the catches 46a and 46b are elastic catches.

When the ion generating component is installed, the ion generating component is inserted into the accommodating cavity 40 of the housing through the clamping grooves 45a and 45b, when the ion generating component is inserted into the rear cavity of the accommodating cavity 40, the bearing substrate 41 presses the buckles 46a and 46b, at the moment, the buckles 46a and 46b elastically deform and are propped open and clamped into the grooves 44a and 44b corresponding to the ion generating component, and therefore the ion generating component is fixed.

The working principle of the embodiment is as follows:

the first wiring port 42b is connected to the output ground of the high voltage power supply, and the second wiring port 43b is connected to the negative high voltage output of the high voltage power supply, because the first wiring port 42b is electrically connected to the ground electrode 42, and the second wiring port 43b is electrically connected to the transmitting electrode 43, the negative voltage equivalent to the high voltage power supply is directly applied between the ground electrode 42 and the transmitting electrode 43, and at this time, the transmitting electrode 43 is at a negative potential, and the ground electrode 42 is at a zero potential. Under the condition of a certain voltage, the smaller the diameter, the stronger the electric field unevenness and the stronger the electric field strength, that is, the front end of the emitter electrode 43 is the place with the strongest electric field, when the voltage output by the high-voltage power supply reaches a sufficient level, the corona discharge phenomenon will occur at the front end of the emitter electrode 43, and a large amount of electrons are generated at the front end of the emitter electrode 43, and form a large amount of negative ions after being combined with air. The smaller the diameter of the emitter electrode 43, the more pronounced the tip curvature discharge effect, and the more negative ions can be generated, as shown in fig. 5, the smaller the voltage required to achieve the same negative ion concentration as the diameter of the emitter electrode 43 decreases, and the easier the negative ions are generated as the diameter of the emitter electrode 43 decreases.

The carrier substrate 41 of this embodiment is made of PCB, and the ground electrode 42 and the emitter electrode 43 are PCB printed lines on the surface of the carrier substrate, and the whole structure is an integrated structure. Because the carrier substrate 41 and the emitter electrode 43 are integrally formed, no additional assembly is needed, and the problem of assembly difficulty caused by the too small diameter of the emitter electrode 43 is not considered, so that the diameter of the emitter electrode 43 can be made as small as possible, the tip curvature discharge effect in the above working principle is more severe, and the ion generation effect of the ion generating component can be greatly enhanced. The emitter electrode 43 is carried by using the carrying substrate 41, when the emitter electrode 43 is acted by external force, the force is not directly acted on the root or the body of the emitter electrode 43, but the force point is transferred to the carrying substrate 41, because the thickness of the carrying substrate 41 can be made thick, the effect of ion generation is not influenced, and the PCB material is not very fragile and can bear enough external force, so that the emitter electrode 43 is not easy to break because of too small diameter, the diameter of the emitter electrode 43 can be made smaller, and the reliability of the ion generating component can be synchronously improved.

Second embodiment

Referring to fig. 6 and 7, in the present embodiment, the ion generating component includes a carrier substrate 41, a protrusion 41a, a left protrusion 41b, a right protrusion 41c, two ground electrodes 42a, a first wiring port 42b, two emitter electrodes 43a, and a second wiring port 43 b.

The two emitting electrodes 43a are respectively pressed on the upper surface and the lower surface of the convex part 41a, and the root parts of the two emitting electrodes 43a are communicated through the second wiring port 43 b; the two ground electrodes 42a are U-shaped, the two ground electrodes 42a are respectively pressed on the upper surface and the lower surface of the carrier substrate 41, the ends of the U-shaped sides of the two ground electrodes 42a are pressed on the upper surface and the lower surface of the left protruding portion 41b and the right protruding portion 41c, and the roots of the two ground electrodes 42a are communicated with each other through the first wiring port 42 b. The two ground electrodes 42a and the two emitter electrodes 43a belong to a PCB printed line.

The working principle of this embodiment is similar to that of the first embodiment, except that the carrier substrate 41 is pressed with two emitting electrodes and two grounding electrodes, which means that two ion generating components act simultaneously, so as to easily generate more negative ions. Under the condition that the applied voltage is the same, the present embodiment can generate more negative ions than the first embodiment, and the negative ion generating effect is better.
