In the above-mentioned conventional liquid spraying device, the desired deodorizing action is obtained by releasing the fine particles of the deodorant liquid agent into the air and bringing the fine particles into contact with the target substance (odorous substance). Trying to get. However, the conventional ones that expect natural contact have a problem in that it is difficult to bring the emitted fine particles into contact with the odorous substance with high efficiency, and the desired effect cannot be obtained.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a liquid spraying device capable of efficiently contacting fine particles such as a deodorant liquid agent with a target substance to enhance the effect. To do.

[0006]

In order to achieve the above object, in the invention of claim 1, in a liquid spraying device equipped with a spraying nozzle for discharging fine particles of a liquid medicine for deodorizing, disinfecting, etc., spraying of the spraying nozzle While placing the electrode in front of the mouth,
A power supply for applying a predetermined voltage is provided between the spray nozzle and the electrode.

According to the second aspect of the invention, in a liquid spraying device equipped with a spraying nozzle for discharging fine particles of a liquid medicine for deodorizing, disinfecting, etc., a pair of electrodes are arranged opposite to each other in front of the spraying port of the spraying nozzle.

In the case of odorous substances, those that adhere to an object in a liquid state are often negatively charged, and those that float in a gas state are often positively charged. Therefore, they will be attracted to and contact with each other with high efficiency. Further, the highly reactive radical fine particles collide with and contact the neutral (uncharged) odor substance with high efficiency.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example in which the present invention is applied to the conventional apparatus shown in FIG. In the figure, 2 is a vaporized liquid line,
Reference numeral 4 is a vaporizer, 4a is an electric heater, 5 is a first nozzle, 7 is a spray liquid pipe, 8 is a second nozzle, and 9 is a nozzle holder. . Incidentally, both nozzles 5 and 8 are made of metal pipe material.

Reference numeral 10 denotes a metal electrode rod, which is arranged in parallel in front of the second nozzle 8 with a space L, and its tip is located in a spray region T having a substantially conical shape. Reference numeral 11 denotes a DC power source, the negative terminal of which is connected to the second nozzle 8 and the positive terminal of which is connected to the electrode rod 10. The interval L varies depending on the output of the DC power supply 11, but in the case of an output of 5 to 15 kV, it is preferably set to 5 mm or less.

The operation of the above liquid spraying device will be described below. When a high voltage is applied between the second nozzle 8 and the electrode rod 10 while the deodorant liquid agent is sprayed, fine particles of the deodorant liquid agent are generated due to the discharge generated between the second nozzle 8 and the electrode rod 10. In the process of passing through the interval L, it is positively or negatively charged or becomes a highly active radical (free) state, and these charged fine particles R +, R− and radical fine particles R · are released into the air.

In general, among odor substances, substances which are present in the form of fine particles or liquid or adhere to an object, such as trimethylamine, pyridine, acetaldehyde and the like are often negatively charged, and substances which float in a gas state, for example hydrogen sulfide. In many cases, the positively charged fine particles R + are attracted to the negatively charged odor substance, and the negatively charged fine particles R- are attracted to the positively charged odor substance and come into contact with each other. Then
The desired deodorizing effect is exerted on each odorous substance. Also,
With respect to the neutral (uncharged) odor substance, the highly reactive radical fine particles R · collide and contact with high efficiency, and the desired deodorizing action is exhibited.

As described above, according to the above liquid spraying device,
Since the fine particles of the deodorant liquid agent are positively or negatively charged or released as radical fine particles into the air, the positive charged fine particles R + are negatively charged odor substances, and the negative charged fine particles R- are positively charged. It is possible to contact each of the odorous substances with high efficiency with each other, and also to collide and contact the radical fine particles R with a neutral (uncharged) odorous substance with high efficiency, as compared with the conventional device that relies on natural contact. The contact efficiency can be remarkably enhanced and an excellent deodorizing effect can be obtained. Further, by the above contact, the odorous substance having a positive or negative charge is electrochemically neutralized, whereby the odorous substance can be inactivated and the generation of odor can be suppressed.

FIG. 3 shows a second embodiment of the present invention.
The present invention is applied to a pressure type liquid spraying device.
In the figure, 21 is a liquid supply pipeline, 22 is a nozzle adapter connected to the end of the liquid supply pipeline 21, and 23 is a spray nozzle provided at the tip of the nozzle adapter 22. The other end of the liquid supply pipe 21 is inserted into a tank (not shown) containing a deodorant liquid agent, and a pump (not shown) for pumping the deodorant liquid agent into the nozzle adapter 22 is provided in the middle of the pipe line. It is installed.

Reference numeral 24 denotes a pair of metal electrode rods, which are arranged in front of the spray nozzle 23 at an interval L so as to face each other, and their tips are located in a spray region T having a substantially conical shape. 25 is a DC power supply, the negative terminal of which is one electrode rod 2
A positive terminal is connected to the other electrode rod 4 respectively.
The interval L and the output of the DC power supply 11 are the same as in the previous embodiment.

In the above liquid spraying device, the deodorant liquid agent pressure-fed into the nozzle adapter 22 can be atomized by the spray nozzle 23 and blown out forward. When a high voltage is applied to both electrode rods 24 in this sprayed state, discharge generated between both electrode rods 24 causes the fine particles of the deodorant liquid agent to be positively or negatively charged in the process of passing through the interval L, or in a radical state. Thus, the charged fine particles R +, R− and the radical fine particles R · are released into the air. Other actions and effects are similar to those of the previous embodiment.

It should be noted that the electrode rods shown in the embodiments may be replaced by ones having a shape other than the rods, and the number thereof may be appropriately increased. Further, in the examples, the case where the deodorant liquid agent is sprayed has been described as an example, but the same action and effect can be obtained even when spraying another kind of liquid agent such as a sterilizing liquid agent or a disinfecting liquid agent. . Further, it goes without saying that the present invention can be applied to various liquid spraying devices other than the illustrated examples.

[0019]

As described above in detail, according to the inventions of claims 1 and 2, fine particles of liquid chemicals for deodorization, disinfection, etc. are positively or negatively charged or released as radical fine particles into the air. Therefore, the positively charged fine particles are brought into contact with the negatively charged target substance, and the negatively charged fine particles are brought into contact with the positively charged target substance with high efficiency, and the radical fine particles are brought into contact with the neutral (uncharged) target substance with high efficiency. It is possible to collide and contact with each other with high efficiency, and it is possible to significantly improve the contact efficiency and obtain an excellent deodorizing effect as compared with the conventional device that relies on natural contact.
