The following describes a specific structure of the electronic device with reference to the drawings by taking specific embodiments as examples.

As shown in fig. 2, an embodiment of the present application provides an electronic device 100, where the electronic device 100 may include at least: the air conditioner comprises a housing 10, wherein at least one air inlet 101 may be formed in the housing 10, and a first air supply device 20 is disposed on a side of the at least one air inlet 101 facing the inside of the housing 10. The first air blowing device 20 is used for heat dissipation, for example, the first air blowing device 20 may be used for sending external cold air into the interior of the casing 10.

Specifically, a side of the at least one air inlet 101 facing the inside of the casing 10 is provided with the first air supply device 20, that is, the first air supply device 20 is located inside the casing 10, and the first air supply device 20 is disposed near the air inlet 101.

It should be noted that the housing 10 is used to protect the internal structure of the main body 12, and specifically, the housing 10 may be a whole structure or may be formed by assembling a plurality of parts. In some embodiments, the housing 10 may include a C-shell and a D-shell. The shell C and the shell D are involuted to enclose the inner accommodating space of the housing 10. Wherein, C shell and D shell can be fixed through the joint, also can be fixed through gluing, can also be fixed through threaded connection, and this application embodiment does not do specific limitation here.

It is understood that the ionizer is a method of generating negative ions by boosting the power frequency voltage to a desired voltage using a high voltage transformer and discharging the negative ions into the surrounding air. In other words, such an apparatus for artificially generating air anions is called an air anion generator or an anion generator, which is simply called an ionizer. Specifically, the negative ions are generated by raising a low voltage to a direct current negative high voltage by a pulse and oscillation electric appliance through a negative ion generator, generating a high corona by utilizing the direct current high voltage at the tip of a carbon brush, and releasing a large amount of electrons (e-) at a high speed, wherein the electrons can not exist in the air for a long time (the existing electrons have the service life of nS grade), and can be immediately captured by oxygen molecules (O2) in the air to form the negative ions.

In the related art, the static electricity cannot be actively removed after the surface of the fan is charged with the static electricity, so that the dust is adsorbed, and the dust is accumulated on the fan to influence the air outlet and efficiency of the fan, thereby increasing the load of the motor and increasing the overall noise of the electronic device 100. Or, the dust still can pile up at the air outlet, influences the air-out efficiency of air outlet to further increase motor load, produce the noise. Moreover, no matter dust is accumulated in the fan, the air outlet or the whole machine, the dust can affect the heat dissipation of the electronic device 100 to a certain extent, and further the overall performance and the user experience effect of the electronic device 100 are affected.

In the electronic device 100 provided in the embodiment of the present application, the first air supply device 20 is disposed on one side of the air inlet 101 facing the inside of the housing 10, and the ion generator 30 is disposed at a position close to the first air supply device 20, so that when the first air supply device 20 sends outside cold air into the inside of the housing 10, ions generated by the ion generator 30 can flow into the first air supply device 20.

Like this, utilize ion wind to produce the principle, the charged ion that ion generator 30 produced can take place static neutralization with first air supply arrangement 20 to make the dust lose the adsorption efficiency on first air supply arrangement 20, alleviate or avoid the problem that the dust piles up on the fan easily or around the fan among the prior art, thereby alleviate or avoid the dust to pile up air-out and the efficiency that influences the fan on the fan, thereby increase motor load, make the problem of the whole noise increase of electronic equipment 100, thereby can promote electronic equipment 100's performance.

In addition, first air supply arrangement 20 can also send whole air current to the reachable region of casing 10 inside with charged ion wind, and charged ion can also take place static neutralization with the inner structure of casing 10 and regions such as air intake 101 promptly, so that the dust loses adsorption efficiency, avoids outside dust to glue the problem that falls in inside and air intake 101 department of casing 10, thereby can avoid to a certain extent producing the influence to electronic equipment 100's heat dissipation, and then can improve electronic equipment 100's wholeness ability and user experience effect.

In addition, the electronic apparatus 100 can also remove dust by taking the dust out of the first air blowing device 20, the internal structure of the casing 10, the air inlet 101, and other areas by the airflow of the first air blowing device 20. Therefore, compared with the prior art, the electronic device 100 provided by the embodiment of the application can realize dust removal without disassembling the machine, is convenient to clean, and can reduce the workload of disassembling and removing dust to a certain extent besides avoiding the problems that dust is difficult to clean or short circuit is easily caused due to long-term accumulation.

In the embodiment of the present application, the positional relationship between the ionizer 30 and the first air blowing device 20 includes, but is not limited to, the following two possible implementations:

one possible implementation is: referring to fig. 2 and 3, the ionizer 30 is located on a side of the first air blowing device 20 facing the air intake opening 101 in the axial direction of the first air blowing device 20. That is, the ion generator 30 is disposed in an overlapping manner with the first air blowing device 20 (see fig. 3), so that under the action of the airflow generated by the first air blowing device 20, the charged ions generated by the ion generator 30 can be electrostatically neutralized with the first air blowing device 20, so that the dust loses the adsorption capacity at the positions on the first air blowing device 20, inside the housing 10, at the air inlet 101, and the like, and the problem that the external dust is adhered to the first air blowing device 20, inside the housing 10, and at the air inlet 101 is avoided.

It should be noted here that the ion generator 30 may be located on either side of the first air blowing device 20 in the axial direction of the first air blowing device 20. That is, when the ion generator 30 is disposed in an overlapping manner with the first air blowing device 20, the ion generator 30 may be located above the first air blowing device 20 (see fig. 3), or in some other embodiments, the ion generator 30 may also be located inside the first air blowing device 20, which is not limited in this embodiment.

Here, the axial direction of the first air blowing device 20 refers to an extending direction of a rotating shaft of the first air blowing device 20, that is, an air outlet direction of the first air blowing device 20.

In addition, it should be understood that, in fig. 3, the flow direction of the first air flow F1 is the direction in which the external cold air enters the electronic device 100 through the air inlet 101 and then blows towards the first air blowing device 20 and the ionizer 30.

Another possible implementation is: referring to fig. 4 and 5, the ionizer 30 is located on one side of the first air blowing device 20 in the direction perpendicular to the axial direction of the first air blowing device 20 (see fig. 5).

Thus, under the action of the airflow generated by the first air supply device 20, the charged ions generated by the ion generator 30 can be electrostatically neutralized with the first air supply device 20, so that the dust loses the adsorption capacity at the positions on the first air supply device 20, inside the housing 10, at the air inlet 101, and the like, and the problem that the external dust is stuck on the first air supply device 20, inside the housing 10, and at the air inlet 101 is avoided.

It should be understood that, in fig. 5, the flow direction of the first air flow F1 is the direction in which the external cold air enters the electronic device 100 through the air inlet 101 and then blows towards the first air blowing device 20 and the ion generator 30. The second airflow F2 is a direction of the ion airflow generated by the ion generator 30 to the first air supply device 20.

It should be noted that the ion generator 30 and the first air blowing device 20 may be in other positional relationships, and the embodiment of the present application is not limited to this, and is not limited to the above example. Moreover, the ion generator 30 and the first air blowing device 20 can be arranged in a more compact manner, so that the occupied space of the ion generator in the electronic device 100 can be saved, and the available space can be provided for other electronic devices in the electronic device 100.

In addition, as an alternative embodiment, the ion generator 30 may be located on the first air blowing device 20. The ion generator 30 is located on the first air supply device 20, so that the distance between the ion generator 30 and the first air supply device 20 is shorter, and further, the neutralization effect of the charged ions generated by the ion generator 30 and the static electricity generated by the first air supply device 20 is better, so that the adsorption capacity of dust on the first air supply device 20, in the shell 10, at the air inlet 101 and the like is better reduced or avoided.

It is understood that the ion generator 30 may be non-detachably mounted on the first air blowing device 20, for example, by bonding, screwing, pinning or snapping, etc., wherein the specific structure of the detachable connection is not limited in this embodiment.

Alternatively, in some other embodiments, the ion generator 30 and the first air blowing device 20 may be connected in a non-detachable manner, for example, the connection end of the ion generator 30 and the connection end of the first air blowing device 20 are both made of metal, and in this case, the two may be connected by welding.

In the embodiment of the present application, the ion emitting end of the ion generator 30 may face the first air blowing device 20. The ion emitting end of the ion generator 30 faces the first air supply device 20, so that the charged ions emitted by the ion emitting end of the ion generator 30 can be more concentrated and sufficiently emitted to the first air supply device 20, and the neutralization effect of the charged ions generated by the ion generator 30 and the static electricity generated by the first air supply device 20 is better, so that the adsorption capacity of dust on the first air supply device 20, in the shell 10, at the air inlet 101 and other positions can be better reduced or avoided.

It is understood that the ions emitted from the ion emitting end are negative ions or positive and negative ions. The electrostatic ions generated by the dust are positive ions, and the ions emitted by the ion emitting end of the ion generator 30 are negative ions or positive and negative ions, so that the ions emitted by the ion emitting end of the ion generator 30 can be ensured to be neutralized with the electrostatic interaction, and the electrostatic adsorption capacity of the dust is reduced or avoided.

In addition, in a possible implementation manner, at least one second air supply device (not shown in the figure) is further disposed on the ion generator 30, a rotating shaft of the second air supply device may be coaxially connected with a rotating shaft of the ion generator 30, and the second air supply device is configured to cooperate with the first air supply device 20 to form a directional air flow. The second air supply device can cooperate with the first air supply device 20 to form a directional airflow so as to enhance the airflow direction between the first air supply device 20 and the ion generator 30, so that more airflow generated by the first air supply device 20 is blown to the ion generator 30.

In addition, referring to fig. 2, at least one air outlet 102 may be further formed on the housing 10, an air duct is formed between the air inlet 101 and the air outlet 102, and the ion generator 30 is located in the air duct. It should be noted that the air duct is located inside the internal structure of the electronic device 100.

The ion generator 30 is located in the air duct between the air inlet 101 and the air outlet 102, and can ensure that the first air supply device 20 supplies the charged ion wind into the whole air duct, so that the charged ions can be neutralized with static electricity in other structures in the air duct, the air outlet 102, the air inlet 101 and other areas, so that the dust loses adsorption capacity, and the problem that external dust is stuck inside the air duct, at the air outlet 102 and the air inlet 101 is avoided.

In addition, the electronic apparatus 100 can also remove dust by taking the dust out of the air duct from the air outlet 102 by the airflow of the first air blowing device 20.

In the present embodiment, the ionizer 30 is a rotary type ionizer that adjusts the distance between two electrodes by relative rotation between the electrodes.
