Description

[Technical field]

[0001] The present invention relates to an atomizing solvent spraying device that can easily confirm the use of the device to spray ultrafine particles of a solvent of 1 μm or less. [Background technology]

[0002] Chemical substances called phytoncides are released or released from plants or trees when the plants are damaged, and have the effect of suppressing the activity of microorganisms and also have bactericidal properties. Recently, in order to obtain the pseudo-healing and relaxing forest bathing effect, it has become common to atomize or spray a diluted solution of artificial phytoncide solvents obtained through the analysis of natural components.

[0003] For example, Patent Document 1 discloses a deodorizing method in which an aqueous deodorant solution is atomized into a mist by ultrasonic oscillation, an airflow carrying the atomized mist produced by ultrasonic oscillation is directed at an ultrafine particle selection plate positioned facing downwards, and coarse particle mist exceeding 3 microns is allowed to fall under its own weight and removed from the airflow, thereby selecting ultrafine particle mist of 3 microns or less from the atomized mist and blowing it together with the airflow into the atmosphere to be deodorized.

[0004] Patent Document 1 also discloses a deodorizing device comprising: a housing having an air outlet at an upper portion; a storage tank housed within the housing and storing an aqueous deodorant solution, the storage tank having a sealed structure with a supply port for the aqueous deodorant solution at a lower end; an atomization tank housed in the lower portion of the housing, the supply port of the storage tank being positioned at a predetermined liquid level so that the aqueous deodorant solution is naturally supplied from the storage tank to the predetermined liquid level, and the supplied aqueous deodorant solution is atomized by ultrasonic oscillation; a fan provided behind the air outlet in the housing for supplying air toward the air outlet; a guide tank provided vertically within the housing, communicating with the main liquid level of the atomization tank and the air outlet, with a peripheral wall inclined so as to reduce its cross-sectional area toward the top, so that droplets scattered from the liquid level of the atomization tank hit the guide tank and fall under its own weight, while the mist atomized and scattered from the atomization tank is sucked in by the air flow of the fan, causing ultra-fine particle mist of 1 μm or less to be carried on the air flow without substantially coagulating; and a control device for operating the ultrasonic oscillator and the fan.

[0005] However, the device described in the above Patent Document 1 ejects only ultrafine particles of 1 μm or less. In order to achieve this, a large space was required from the position of the guide tank and the ultrasonic oscillator toward the outlet, and the structure required for atomization and blowing out was about twice as large as the storage tank in terms of volume ratio, which was an obstacle to miniaturization.In addition, the flow path for blowing air from the fan and the blowing flow path for fine particles were provided separately, and the ultra-fine particles and the blown air were merged at the outlet with a louver, which was also an obstacle to miniaturization.

[0006] On the other hand, there are problems with miniaturization, and it is not enough to simply reduce the scale of all the components in the configuration of Patent Document 1, for example by making the solvent tank smaller. It is desirable to guarantee a certain amount of solvent, in other words, to keep the tank or bottle filled with the solvent constant, and to only miniaturize the device itself, while maintaining the usage period of the solvent approximately the same as before.

[0007] In order to solve the above problem, Patent Document 2 proposes an atomized solvent discharge device having an outlet cap provided on the top surface of a cover constituting an atomization tank, the outlet cap having an outlet formed on the side surface and two walls formed on the back surface, the cover having an air passage formed in the height direction of the side surface, partitioned from the inside of the atomization tank and communicating with the delivery section, a mist air passage formed by fitting a protrusion formed on the top surface of the cover with the wall surface of the outlet cap and communicating with the air passage, a straightening protrusion formed in the center of the width direction midway through the flow path of the mist air passage and adjusting the air flow, an air inlet hole formed just before the flow path of the straightening protrusion and allowing air to flow into the inside of the atomization tank, and a mist exhaust hole formed on the top surface of the cover at the end opposite the side communicating with the air passage of the mist air passage and communicating with the inside of the atomization tank.

[0008] By doing this, the size of the device was certainly reduced, and the usage period of the solvent remained almost the same as before; in fact, because ultrafine particles of 1 μm or less are sprayed and solvent with a larger particle size is returned to the atomization tank, the usage period has been extended.

[0009] However, ultrafine particles of 1 μm or less cannot be seen with the naked eye, making it impossible to confirm whether the solvent is actually being sprayed or not. Even if one were to make the inside of the atomization tank visible so as to show the atomization state before the particles are separated into ultrafine particles of 1 μm or less and larger particles, all one could see was the inside filled with white mist, and it was not possible to confirm the state of separation.

[0010] [Patent Document 1] Patent No. 3067089 [Patent Document 2] JP 2016-34610 A Summary of the Invention [Problem to be solved by the invention]

[0011] The problem that the present invention is intended to solve is that with conventional devices for spraying a solvent of ultrafine particles of 1 μm or less, it is difficult to check the use of the device when spraying ultrafine particles. [Means for solving the problem]

[0012] In order to solve the above problems, the present invention provides an atomized solvent spraying device that atomizes a solvent stored in the lower part of a housing with an ultrasonic vibrator, separates the atomized solvent by particle size, sprays small particles and returns large particles to the storage side, and includes a window section through which the ultrasonic vibrator is provided at the bottom and through which the inside of a solvent atomization tank filled with and stored with the solvent atomized by the ultrasonic vibrator is viewed, a solvent spray section provided above the solvent atomization tank, and a solvent spray section for spraying the solvent. spray The housing further includes an atomized solvent separating member provided in the solvent spraying section for suppressing the rise of atomized solvent having a large particle size among the atomized solvent and for guiding atomized solvent having a small particle size to a spray nozzle, and a mist adjusting member provided so as to surround the ultrasonic vibrator for achieving a uniform atomized state. A fan is provided on the upper part of the housing in which the solvent spraying section is located, and the atomized solvent separating member further includes a suction hole which functions as an ejector that sucks the inside of the solvent atomization tank with the airflow of the fan. Effect of the Invention

[0013] In the present invention, since the window is provided, it is possible to visually check whether the tank is in operation or not by looking into the inside of the tank. In this case, the solvent is atomized by the ultrasonic vibrator inside the tank, which can be seen through the window, and the mist control member can make the atomized solvent homogenous. Also, the atomized solvent separation member can suppress the rise of the homogenous atomized solvent to a certain height, so that the surface seen through the window is not only the atomized solvent, and the upper surface of the atomized solvent can be made to look like a sea of ​​clouds.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The present invention is an apparatus for spraying ultrafine particles of solvent of 1 μm or less, and the purpose of confirming the use of the ultrafine particles is achieved by a window part for looking into the inside of a solvent atomization tank in which an ultrasonic vibrator is provided at the bottom and the solvent atomized by the ultrasonic vibrator is filled and stored, a solvent spray part provided above the solvent atomization tank, and a solvent spraying part for spraying the solvent. sprayThe present invention is achieved by providing an atomized solvent separating member that is provided in the housing in which the solvent spraying section is provided, for suppressing the rise of the atomized solvent having a large particle size among the atomized solvent and for guiding the atomized solvent having a small particle size to the spray nozzle, and a mist adjusting member that is provided so as to surround the ultrasonic vibrator and for making the atomized state uniform, providing a fan on the upper part of the housing in which the solvent spraying section is provided, and further providing a suction hole in the atomized solvent separating member that functions as an ejector that sucks the inside of the solvent atomization tank with the airflow of the fan. did.

[0016] The present invention was invented in the following circumstances: For example, in the conventional configurations described in Patent Documents 1 and 2, when a window was provided to visually check the atomization state of the solvent, all that was visible was the state in which the part corresponding to the solvent atomization tank was filled with pure white atomized solvent, and it was possible to see only that the solvent was being atomized by the ultrasonic vibrator, but it was not possible to see the state in which the particle size of the atomized solvent was separated into large and small.

[0017] In addition, for example, in the configurations of Patent Documents 1 and 2, the atomized solvent seen through the window fills the area corresponding to the solvent atomization tank, but sometimes the atomized solvent is partially missing or the height is low only in the center, making the generated atomization state unstable, which can lead to the mistaken belief that there is a problem with the ultrasonic vibrator.

[0018] In light of the above, the inventors have developed a device that allows the operating status to be checked through a window, while also ensuring that particle size separation is appropriate, that the atomization state seen through the window is stable, and that the appearance of the atomized solvent seen through the window is good. As a result, they have decided to provide an atomized solvent separation member and a mist control member.

[0019] That is, by providing the mist control member, it is possible to prevent foaming around the ultrasonic vibrator, thereby uniformly atomizing the solvent and stabilizing the amount of atomization (consumption) per unit time. Also, by providing the atomized solvent separation member, only invisible particles with a particle size of 1 μm or less are sprayed, and the rise of larger visible particles in the solvent atomization tank is suppressed, so that the separation status can be visually grasped. By providing these, the atomized solvent seen through the window can be made to look good, floating like a sea of ​​clouds in the center of the height direction of the window.

[0020] In the above-mentioned configuration, the present invention may be configured to provide a color-changing lighting means near the window. This can make the atomized solvent seen through the window look more attractive, and can achieve a variety of desired effects, as well as an effect of informing the user of errors or troubles by color, and a psychological effect of making the user feel relaxed when looking at the window at certain times. EXAMPLES

[0021] An embodiment of the present invention will be described below with reference to Figs. 1 to 11. Fig. 1 shows a schematic configuration of an atomized solvent spraying device 1 (hereinafter referred to as spraying device 1) of the present invention, and in this embodiment, the spraying device 1 has the following configuration. The spraying device 1 in this embodiment has an optimal configuration for atomizing and discharging a phytoncide solvent (hereinafter referred to as solvent). Hereinafter, the atomized state of this solvent will be referred to as mist.

[0022] Reference numeral 2 denotes a housing that houses the control unit and other units described below. The housing 2 is roughly divided into a solvent storage section 2A that stores the solvent, a solvent atomization tank 2B that turns the solvent into mist, and a solvent spray section 2C that sprays the solvent. One of the long sides of the housing 2, which is the front side, is provided with a window section 2D that does not cover the inside of the solvent atomization tank 2B.

[0023] Here, we will explain the basic operation of the spraying device 1 of the present invention. As shown in Figures 1 and 2, in the spraying device 1 of the present invention, the solvent contained in the solvent container 2A is supplied to the solvent atomizing tank 2B, where it is turned into mist, and the mist is sprayed from the solvent spraying section 2C.

[0024] The solvent spraying section 2C sprays mist with invisible particle diameters (1 μm or less), and returns mist with visible particle diameters (larger than the above) and a portion of the air blown for spraying the mist with invisible particle diameters to the solvent atomization tank 2B.

[0025] The air flow returning to the solvent atomization tank 2B restricts the visible particle size in the solvent atomization tank 2B from rising to about half the height of the window 2D, and the particles float in the tank. When viewed through the window 2D, the mist appears to be smoothly and slowly rippling like a sea of ​​clouds, and as long as the sea of ​​clouds-like mist is visible, it can be understood that the system is operating normally. Meanwhile, only small particles of the mist filling the solvent atomization tank 2B rise to the solvent spray section 2C against the returning air flow.

[0026] To achieve the above operation, we will return to the description of the configuration. In this example, 3 shown in Fig. 1 is a tank that contains a solvent. The tank 3 is designed to be placed in the solvent storage section 2A of the housing 2 with the cap of the bottle removed and the cap side facing downward.

[0027] Reference numeral 4 denotes a storage section provided at the inner bottom of the solvent atomization tank 2B of the housing 2. Specifically, this storage section 4 stores the solvent flowing out from the tank 3 via a supply path 2a connected to an outlet on the cap side of the tank 3 facing downward. The supply path 2a is provided with a gentle incline from the solvent storage section 2A side toward the solvent atomization tank 2B, with the solvent atomization tank 2B side facing downward, so that a fixed amount of solvent is supplied from the tank 3 every time the solvent is consumed from the storage section 4.

[0028] As shown in Figure 4 etc., the storage section 4 is a circular depression in a plan view, and is formed with an upper section 4a whose peripheral portion is connected to the supply path 2a, and a lower section 4b which is coaxial with the upper section 4a and is lower (deeper) by a predetermined height, and an ultrasonic oscillator section 5 described later is provided in the center of the lower section 4b.

[0029] Reference numeral 5 denotes an ultrasonic oscillator (hereinafter, referred to as oscillator 5) that is provided in a further recessed portion provided in the center of the lower stage 4b ​​of the storage section 4 and that uses an ultrasonic oscillator to turn the solvent stored in the storage section 4 into mist. This oscillator 5 turns the phytoncide solvent into mist by vibrating the oscillator at, for example, about 2.5 MHz.

[0030] Reference numeral 6 denotes a mist control member provided in storage section 4 so as to surround oscillation section 5. As shown in Fig. 4, Fig. 10, etc., mist control member 6 is cylindrical with a flange portion 6a formed at one end in the axial direction and a plurality of notches 6b formed at the other end, for example, at intervals of about 60 degrees in this example.

[0031] The mist control member 6 also has a partition 6c for blocking the solvent attempting to flow above the oscillation unit 5 and spraying only the mist directly above the oscillation unit 5. This partition 6c is cylindrical with an inner diameter equal to the outer diameter of the oscillation unit 5, and is supported by three supports 6d provided coaxially with the mist control member 6 and at equal angles of, for example, 120 degrees, and an edge portion 6e is formed in which the outer diameter (thickness) becomes gradually smaller toward the edge portion on the oscillation unit 5 side when placed on the storage unit 4.

[0032] In this example, the mist control member 6 has an outer cylinder portion with a height (axial length) of, for example, 40 mm as a whole, and the partition portion 6c which forms the inner cylinder has a height (axial length) of 25 mm. The tip of the partition portion 6c (edge ​​portion 6e) is spaced 10 mm from the oscillation portion 5, and the tip protrudes 8 mm beyond the end of the outer cylinder portion on the side where the notch portion 6b is formed.

[0033] By forming the mist control member 6 in this manner, in this example, it is possible to create a sea of ​​mist with stable visible particle sizes suspended in a cloud-like fashion at a height of 60 to 80 mm from the inner bottom surface of the storage section 4 (corresponding to approximately the center part in the height direction of the window section 2D), and consumption of 1 liter of solvent can be maintained for approximately one month (32 days) when used for 8 hours per day.

[0034] The mist control member 6 works as follows: The flange portion 6a prevents the solvent stored in the storage portion 4 and the solvent that becomes foamed when supplied to the storage portion 4 from entering the partition portion 6c. That is, the important factors for the mist control member 6 are the distance from the oscillation portion 5 to the tip of the partition portion 6c, the amount of protrusion of the partition portion 6c from the outer cylinder portion, and the presence or absence of the edge portion 6e.

[0035] The distance between the tip of the partition 6c of the mist control member 6 and the oscillation unit 5 is 5 to 10 mm. If the distance between the tip of the partition 6c of the mist control member 6 and the oscillation unit 5 is closer than 5 mm, the amount of solvent flowing into the oscillation unit 5 in the partition 6c is small, and the vibration of the oscillation unit 5 may cause the solvent to foam in the mist, generating a sea of ​​cloud-like mist at a position lower than the target predetermined height. On the other hand, if the distance is longer than 10 mm, the opposite is true: the amount of solvent flowing into the oscillation unit 5 in the partition 6c is large, and there is a possibility that more solvent than necessary will be consumed, and a sea of ​​cloud-like mist will be generated at a position higher than the target predetermined height.

[0036] The protruding amount of the partitioning portion 6c from the outer cylinder portion of the mist control member 6 is 5 to 10 mm. If the protruding amount of the partitioning portion 6c from the outer cylinder portion of the mist control member 6 is shorter than 5 mm, the distance between the lowest end of the outer cylinder portion and the upper stage portion 4a of the storage portion 4 is small, so less solvent flows into the outer cylinder portion, and a sea of ​​cloud-like mist is generated at a position lower than the target predetermined height, whereas if it is longer than 10 mm, the distance between the lowest end of the outer cylinder portion and the upper stage portion 4a of the storage portion 4 is large, so more solvent flows into the outer cylinder portion, and there is a possibility that more solvent will be consumed than necessary, and a sea of ​​cloud-like mist is generated at a position higher than the target predetermined height.

[0037] If the edge portion 6e of the partition portion 6c of the mist control member 6 is not present, then as shown in Fig. 11(a), the mist generated by the oscillation unit 5 that heads other than directly above the oscillation unit 5 collides with the lower end face of the partition portion 6c, generating turbulence and preventing the mist from heading straight up, resulting in a loss. On the other hand, if the edge portion 6e is provided, then as shown in Fig. 11(b), the mist generated by the oscillation unit 5 that heads other than directly above the oscillation unit 5 heads outside the partition portion 6c without generating turbulence, and no loss is generated.

[0038] As described above, the mist control member 6 can control the amount of solvent consumption by adjusting, within the above-mentioned ranges, the distance between the tip of the partition section 6c of the mist control member 6 and the oscillation section 5, and the amount of protrusion of the partition section 6c relative to the outer tube portion of the mist control member 6.

[0039] Reference numeral 7 denotes an atomized solvent separating member (hereinafter, referred to as separating member 7) provided in the solvent spraying section 2C located in the upper part of the solvent atomizing tank 2B. As shown in Fig. 3 and Figs. 5 to 9, the separating member 7 sprays only the atomized solvent having a very small and light particle size of 1 µm or less from the atomized solvent filling the solvent atomizing tank 2B, and returns the rest to the solvent atomizing tank 2B, while applying an appropriate pressure to the inside of the solvent spraying section 2C.

[0040] The separating member 7 not only separates the atomized solvent so that only small particle diameters are sprayed, but also applies an appropriate pressure toward the solvent atomization tank 2B, thereby causing the visible particle diameters to suspend at a height approximately half the internal height of the solvent atomization tank 2B (height 9 of the window portion 2D) as described above, and allowing only the invisible particle diameters to rise toward the solvent spray section 2C.

[0041] 1 to 3, the solvent spraying section 2C is composed of a fan 7A at the upper part of the housing 2 on the side opposite to the side where the window section 2D is provided in the center in the width direction, an inclined section 7B inclined upward toward the side where the window section 2D is provided with the lowest point immediately before the fan 7A, and a communication hole 7C formed at the lowest position of the inclined section 7B and communicating with the solvent atomization tank 2B. In this example, the solvent spraying section 2C is provided with an openable and closable cover 7D for covering the entire area of ​​the inclined section 7B.

[0042] The separating member 7 is adapted to fit into the communication hole 7C so as to have the same inclined surface as the inclined portion 7B. In other words, the separating member 7 is sized to fit into the communication hole 7C from above, and engagement portions 7b are formed at, for example, the four corners in a plan view of the inclined surface 7a of the upper surface, which has the same inclined surface as the inclined portion 7B, so as to prevent the entire separating member 7 from falling into the communication hole 7C.

[0043] In addition, the separating member 7 is formed with suction holes 7c on both sides of the width direction (horizontal direction with the window part 2D in the housing 2 at the center) divided at the center of the inclined surface 7a. The suction holes 7c function as ejectors and are for sucking the mist in the solvent atomization tank 2B by the airflow along the inclined surface 7a by the fan 7A.

[0044] Furthermore, on the end face (referred to as the bottom face) of each suction hole 7c opposite to the inclined face 7a, a wall face 7d protruding from the bottom face across the entire width of each suction hole 7c, and a separating section 7e is formed by bending the bottom end of the wall face 7d perpendicularly to cover the entire hole of the suction hole 7c when viewed from the bottom. The wall face 7d and the separating section 7e make the path from the suction hole 7c to the inclined face 7a into a bent path, so that only the mist with a smaller particle size (smaller surface tension) can be separated from the mist filled in the solvent atomization tank 2B and sucked into the suction hole 7c.

[0045] In addition, the separating member 7 has a collision part 7f protruding from the center of the inclined surface 7a, and a communication hole 7g communicating with the solvent atomization tank 2B is formed at the bottom of the collision part 7f. In this example, the collision part 7f is, for example, triangular prism-shaped, with one corner located above the inclined surface 7a and one side located below the inclined surface 7a. The collision part 7f causes the air sent from the fan 7A to collide with the surface of the one side, and the communication hole 7g causes the collided air to flow into the solvent atomization tank 2B.

[0046] Furthermore, the separating member 7 has a wall surface 7h that protrudes from the lower surface of the communication hole 7g over the entire width of the communication hole 7g, and a direction changer 7i that is formed by bending the lower end of the wall surface 7h perpendicularly and covering the entire hole of the communication hole 7g when viewed from the bottom. The wall surface 7h and the direction changer 7i for allowing air to flow into the solvent atomization tank 2B are different from the wall surface 7d and the separating part 7e for sucking the mist from the solvent atomization tank 2B in the following points.

[0047] That is, wall surface 7d protrudes downward from the side opposite to the window portion 2D of communication hole 7c, while wall surface 7h protrudes downward from the window portion 2D side of communication hole 7g. Also, separation portion 7e is bent perpendicularly from wall surface 7d toward the window portion 2D side, while direction change portion 7i is bent perpendicularly to the side opposite to the window portion 2D.

[0048] By using the collision section 7f, the communication hole 7g, the wall surface 7h, and the direction change section 7i to cause air to flow into the solvent atomization tank 2B from a direction different from the direction in which the mist is sucked in, turbulence is generated within the solvent atomization tank 2B, and the mist is sucked in from the solvent atomization tank 2B via the suction hole 7c, the wall surface 7d, and the sorting section 7e, so that only the mist with smaller particle size and lighter particle size is sorted out, while the mist with visible particle size that fills the solvent atomization tank 2B is pushed back to the storage section 4 in an appropriate amount.

[0049] In other words, in the spray device 1 of the present invention, due to the synergistic action of the mist control member 6 and the sorting member 7, when viewed through the window portion 2D, it is possible to create the effect of a sea of ​​mist with visible particle size floating with its upper end located approximately at the center in the height direction of the solvent atomization tank 2B, thereby making it possible to visually confirm with certainty that the device is operating normally.

[0050] Reference numeral 8 denotes a light-emitting unit as a lighting means provided near the lower edge of the window portion 2D. This light-emitting unit 8 emits light in a color that can be changed by a switch or a predetermined program by a control unit (not shown). By providing this light-emitting unit 8, it is possible to grasp the operating status of the spray device 1 and at the same time effectively produce the mist floating in a sea of ​​clouds in the solvent atomization tank 2B.

[0051] By making the light emitted from the light-emitting unit 8 red, for example, it is possible to create the effect of a flickering bonfire flame as the light is reflected by the mist of visible particle size, and watching this can have a relaxing effect. [Explanation of symbols]
