Description

Spraying device

[ technical field ] A method for producing a semiconductor device

The present invention relates to a spraying device, and more particularly, to a spraying device having an indirect spraying unit.

[ background of the invention ]

Desktop air humidifiers are often used in dry climates by atomizing the liquid in the humidifier to raise the humidity of the air. Generally, the atomization process needs to atomize the liquid into droplets with smaller particle size to avoid the phenomenon of over-wetting caused by too large ejected droplets. In the conventional method, a high-frequency oscillating piece is used to oscillate in a liquid at a high speed to atomize the liquid, however, the heat energy generated in the oscillating process may cause overheating of the machine and increase the risk of machine failure; on the other hand, if liquids with additives (e.g., essential oils, fragrance-added liquids, etc.) are used, the generation of heat energy is more likely to cause deterioration of these liquids.

In view of the above, it is desirable to provide a spray device that can efficiently atomize a liquid into droplets having a small particle size without generating excessive heat energy.

Aside from the details given herein, this invention is capable of broad application to other embodiments and that various other substitutions, modifications, and equivalents may be made in the embodiments without departing from the scope of the invention as defined by the appended claims. In the description of the specification, numerous specific details are set forth in order to provide a more thorough understanding of the invention; however, the present invention may be practiced without some or all of these specific details. In other instances, well-known steps or elements have not been described in detail so as not to unnecessarily obscure the present invention. The same or similar elements in the drawings will be denoted by the same or similar symbols. It is noted that the drawings are for illustrative purposes only and do not represent actual sizes or quantities of elements, and some details may not be drawn completely to simplify the drawings.

Referring to fig. 1, the spraying apparatus 100 of the present invention includes a first liquid storage chamber 101, a nozzle plate unit 20, and an indirect spraying unit 30. Wherein the first reservoir 101 has a reservoir space 10 for storing a liquid 102 to be atomized (as shown in fig. 4). The orifice plate unit 20 is disposed on a sidewall of the first liquid storage chamber 10 for ejecting the liquid 102 to be atomized to form a first atomized liquid droplet 201 (as shown in fig. 4). Please refer to fig. 2, which is a schematic structural diagram of a nozzle plate unit according to an embodiment of the present invention. The nozzle plate unit 20 may include a base 21 and a nozzle plate structure 22, the nozzle plate structure 22 is disposed on the base 21, and the nozzle plate structure 22 has a plurality of conductive contacts 23 electrically connected to a plurality of external contacts 24 on the base 21. The nozzle plate unit 20 is removably mounted on the wall 50 of the first chamber 101, so that the user can easily replace the nozzle plate unit.

The indirect spraying unit 30 may be disposed at a position where the orifice plate unit 20 sprays the first atomized liquid droplets 201 to receive the first atomized liquid droplets 201. Structure of indirect spray unit 30 referring to fig. 3 and 4, the indirect spray unit 30 is a channel structure 300 and has a droplet inlet 304 and a droplet outlet 305, wherein the aperture of the droplet inlet 304 may be larger than the aperture of the droplet outlet 305. The droplet outlet 305 is located on a wall 40 of the spraying device 100, and the droplet inlet 304 is directed towards the orifice plate unit 20 where the first atomized droplets 201 are ejected. The channel structure 300 has a first surface 301, a second surface 302, and a pair of third surfaces 303, wherein the first surface 301 and the second surface 302 are opposite to each other and are connected to each other by the pair of third surfaces 303 to form a channel structure 300. Specifically, the first surface 301 is disposed to be inclined at a predetermined angle with respect to the second surface 302, and preferably, the first surface 301 may be disposed to be inclined at an angle of 30 to 80 degrees with respect to the second surface 302. In the drawings of the present invention, the channel structure 300 is exemplarily illustrated as a three-dimensional trapezoid, wherein the first surface 301 is disposed obliquely to the second surface 302. By means of the indirect spraying unit with the channel structure, the liquid drop inlet can receive the first atomized liquid drops sprayed by the spray hole sheet unit to enter the indirect spraying unit, and the first atomized liquid drops continuously impact in the channel structure and are split into liquid drops with smaller particle size, and detailed operation will be described in detail later.

Next, referring to fig. 4, the operation of the spraying device of the present invention will be described in detail. The first atomized liquid droplets 201 formed by the ejection of the liquid to be atomized 102 by the orifice plate unit 201 can enter the indirect spraying unit 30 via the droplet inlet 304 of the channel structure 300. Here, the first atomized liquid droplets 201 can repeatedly collide and reflect on at least two of the first surface 301, the second surface 302 and the third surface 303 of the channel structure 300 to form the second atomized liquid droplets 202, and the second atomized liquid droplets 202 are ejected from the droplet outlet 305. In one embodiment, the first atomized liquid droplet 201 can undergo repeated impinging reflex actions between the first face 301 and the second face 302 of the channel structure 300 to form the second atomized liquid droplet 202. The first atomized droplets can be continuously impacted in the indirect spray unit to break up into second atomized droplets having a smaller particle size.

In another embodiment of the present invention, after the first atomized liquid droplets 201 enter the indirect spraying unit 30, repeated impact reflection actions may be performed on at least two of the first surface 301, the second surface 302 and the third surface 303 of the channel structure 300 to form third atomized liquid droplets 203, wherein the third atomized liquid droplets 203 are ejected toward the liquid droplet inlet 304. In another embodiment of the present invention, the spraying device 100 may further comprise a second liquid chamber 103 disposed around the periphery of the first liquid chamber 101, and the first liquid chamber 101 and the second liquid chamber 103 are connected to each other by a communication unit 104. When the first atomized liquid droplets 201 impact the indirect spray unit 30 to generate third atomized liquid droplets 203 in a direction opposite to the direction of the second atomized liquid droplets 202, the third atomized liquid droplets 203 may fall into the second liquid storage chamber 103, and when accumulated to a certain volume, they may flow back into the first liquid storage chamber 101 through the communication unit 104. By means of the backflow configuration, the liquid can be effectively recycled, and therefore the effects of energy conservation and environmental protection are achieved.

In view of the above, the present invention provides a spraying apparatus having an indirect spraying unit, in which a first surface of the indirect spraying unit is disposed to be inclined to a second surface at a predetermined angle, and by virtue of the above configuration, droplets injected from the orifice plate unit are repeatedly subjected to impact reflection movement, so that the droplets are impacted and received as droplets having a smaller particle diameter, thereby enabling to achieve a more refined liquid atomization effect and to obtain a more optimized spraying quality. In another aspect, the spraying device of the present invention further comprises a recycling arrangement, through which a portion of the droplets rebounded by the indirect spraying unit can be recycled, which has the effect of saving energy and protecting environment.

The above-described embodiments are merely illustrative of the technical spirit and features of the present invention, and the object of the present invention is to enable those skilled in the art to understand the content of the present invention and to implement the same, and the scope of the present invention should not be limited by the above-described embodiments, i.e., all equivalent changes and modifications made in the spirit of the present invention should be covered by the scope of the present invention.
