Description

  The present invention relates to a spray device and a method of using the same.

  In general, a mist generator (a spraying device) that atomizes a liquid containing an active ingredient and sprays it on a human body not only at home but also outdoors is used in various applications such as beauty and medicine.

  For example, the conventional mist generator described in Patent Document 1 applies ultrasonic vibration to a liquid by a vibrator arranged so as to face the metal mesh, atomizes the liquid through the metal mesh, and sprays it on the human body. It is supposed to be. In addition, the mist generators that are currently on the market are equipped with a metal mesh in the device. Each time you use the mist generator, the specified container is filled with the liquid specified by the manufacturer, and this container is set in the device. It has become common practice.

  However, in the conventional mist generator, since the mesh is provided as described above, the mesh cannot be exchanged. For this reason, if the maintenance after use is neglected, the active ingredient in the liquid may be deposited on the mesh. In some cases, after using the mist generator for a long time, bacteria etc. may propagate on a part of the mesh. There is a problem that it is not preferable for hygiene.

  Moreover, in the conventional mist generator, since the mesh is designed according to the kind of liquid to be used, the liquid which can be used with a predetermined mist generator is predetermined. For this reason, the user cannot arbitrarily change the liquid to be used, which is not convenient.

  On the other hand, it is also conceivable that various liquids can be used in the same mist generator by making the mesh used in the spraying device exchangeable. In this case, the mesh can be prevented from deteriorating or becoming unsanitary.

  However, in general, in order to spray liquid from a mesh, it is necessary to vibrate corresponding to the characteristics of the mesh (for example, the diameter of fine holes in the mesh) using a vibrator. For this reason, when the mesh can be exchanged, it is necessary to be able to switch a signal to be sent to the vibrator for each mesh, and there arises a problem that the cost of the spray device becomes high and the operation becomes complicated.

  In the conventional mist generator, the type of liquid to be used is often specified. This is mainly due to the fact that the different liquids used have different viscosities. That is, when the viscosity of the liquid is different, the optimum spraying condition in the mist generator is different.

  For example, when the liquid used in the mist generator has a low viscosity, the frequency of the vibrator that vibrates the mesh is generally set high. In this case, if the liquid to be used is changed from one having a low viscosity to one having a high viscosity, the frequency of the vibrator is high after the liquid is sprayed from the mesh, so that the new liquid cannot sufficiently flow to the mesh. End up. For this reason, there exists a possibility that a liquid cannot be sprayed from a mist generator. Conversely, when the liquid used in the mist generator has a high viscosity, the frequency of the vibrator that vibrates the mesh is generally set low. In this case, if the liquid to be used is changed from one having a high viscosity to one having a low viscosity, the frequency of the vibrator is too low, so that the liquid cannot be sprayed from the mist generator.

  The present invention has been made in view of the above circumstances, and provides a spray device capable of sufficiently spraying a liquid even when the liquid used in the spray device is changed to one having a different viscosity. The main purpose.

(Spraying device)
First, the configuration of a spray device (mist generator) according to an embodiment of the present invention will be described. FIG. 1 is a schematic configuration diagram of a spray device according to an embodiment of the present invention. The spray device described below may be used with a fixed installation location, or may be used by a user with an arbitrary location.

  As shown in FIG. 1, the spray device 1000 is connected to a housing 1010, a liquid cartridge 100 disposed in the housing 1010, a vibration applying unit 1020 that applies vibration to the liquid cartridge 100, and a vibration applying unit 1020. And at least a power supply unit 1030 that supplies power to the vibration applying unit 1020. In the spray device 1000, the atomized liquid 130 is sprayed to the outside of the housing 1010 through a spray port 1015 provided in the housing 1010.

  Although the form of the housing | casing 1010 is not specifically limited, For example, you may have an elongate cylinder shape. As shown in FIG. 1, a control unit 1050 for controlling the spray device 1000 is provided in the housing 1010. The control unit 1050 includes a power supply unit 1030 and an input unit 1040, and a wiring unit 1060. Are electrically connected to each other.

  Although details will be described later, the liquid cartridge 100 includes at least a container portion 110 having a liquid storage portion 112 and a mesh member 120 that is provided so as to cover the opening of the liquid storage portion 112 and includes a plurality of through holes 122. Has been. A liquid 130 is stored in the liquid storage portion 112 of the container portion 110.

  The liquid cartridge 100 is installed such that the mesh member 120 is disposed at a position corresponding to the spray port 1015 of the housing 1010. The arrangement of the liquid cartridge 100 is appropriately set according to the spraying direction of the liquid 130. For example, when the spraying direction of the liquid 130 is a vertical direction, the mesh member 120 is arranged so as to face the vertical direction, and when the spraying direction of the liquid 130 is a horizontal direction, the mesh member 120 is horizontal. Arranged to face the direction. The housing 1010 is formed with an insertion port (not shown) so that the liquid cartridge 100 can be inserted. The position of the insertion port may be an upper part or a side part of the housing 1010. In this case, the liquid cartridge 100 is detachably mounted in the housing 1010 through the insertion port.

  The liquid 130 stored in the liquid cartridge 100 is atomized by predetermined means, passes through the mesh member 120, and is sprayed from the spray port 1015 to the outside of the housing 1010. FIG. 1 shows an example in which the vibration applying unit 1020 vibrates the mesh member 120 and generates a minute mist using the vibration.

  The vibration applying unit 1020 has a function of atomizing the liquid 130 stored in the liquid cartridge 100 by applying ultrasonic vibration to the mesh member 120 by the power supplied from the power supply unit 1030 via the control unit 1050. In the present embodiment, the vibration applying unit 1020 is disposed so as to contact the periphery of the area where the through hole 122 is provided in the mesh member 120. In addition, the vibration applying unit 1020 may have a planar shape made of, for example, an annular shape or a polygonal shape. An example of the vibration applying unit 1020 is a piezoelectric element.

  In FIG. 1, the vibration applying unit 1020 is disposed so as to be in contact with the surface side of the mesh member 120 (the side opposite to the container unit 110), but is not limited thereto. For example, the form which arrange | positions the vibration provision part 1020 in contact with the back surface side (container part 110 side) of the mesh member 120, and provides a vibration to the mesh member 120 by this may be sufficient. Or the form which arrange | positions the vibration provision part 1020 in the bottom face side of the container part 110, and provides a vibration to the liquid 130 in the container part 110 by this may be sufficient.

  As the power supply unit 1030, for example, a battery such as a dry battery or a rechargeable battery can be used. When power supply unit 1030 is made of a rechargeable battery, charging may be performed by a household outlet or sunlight. When a rechargeable battery or the like is not used, the power may be supplied directly by connecting to an outlet via an AC adapter, for example.

  The input unit 1040 turns on / off the power applied from the power supply unit 1030 to the vibration applying unit 1020 of the liquid cartridge 100 via the control unit 1050, and includes, for example, a known power switch.

The control unit 1050 is connected to the vibration applying unit 1020 and plays a role of generating ultrasonic vibrations in the mesh member 120 by supplying power from the power supply unit 1030 to the vibration applying unit 1020. In the present embodiment, as will be described later, the control unit 1050 is configured such that the vibration applying unit 1020 has a low frequency stage S _{1 in} which the frequency of the ultrasonic vibration has a predetermined first frequency f ₁ and the ultrasonic vibration. as frequency is alternately executed and high frequency step S ₂ having a second frequency f _2, and supplies power to the vibration applying unit 1020.

As illustrated in FIG. 1, the control unit 1050 includes an oscillation circuit 1051 connected to the power supply unit 1030, a microprocessor 1052 connected to the oscillation circuit 1051, and a drive circuit 1053 connected to the microprocessor 1052. ing. Among these, the oscillation circuit 1051 outputs a signal having a predetermined frequency and transmits it to the microprocessor 1052. The microprocessor 1052 generates a drive signal for the vibration applying unit 1020 to alternately execute the low frequency stage S ₁ and the high frequency stage S ₂ and outputs the drive signal to the drive circuit 1053. The drive circuit 1053 outputs power (signal) for vibrating the vibration applying unit 1020 based on the drive signal from the microprocessor 1052. Note that a known pulse generator may be used as the control unit 1050.

  Next, the mist generating mechanism of the spray device 1000 will be described with reference to FIGS. 1 and 2A to 2D. 2A to 2D are schematic views for explaining an example of a mist generating mechanism of the spray device 1000. FIG. 2A to 2D, a vibration applying unit 1020 such as a piezoelectric element is provided on the inner side of the mesh member 120 from the position fixed to the container unit 110 and on the opposite side of the liquid 130. Yes.

  FIG. 2A is a diagram illustrating a state in which vibration is not applied to the mesh member 120, and the liquid 130 is in contact with the mesh member 120 due to the surface tension of the liquid 130. When the user presses an input unit 1040 such as a switch provided in the housing 1010, an “ON” signal is transmitted to the control unit 1050. The control unit 1050 supplies power from the power supply unit 1030 to the vibration applying unit 1020 in response to an “ON” signal from the input unit 1040. As a result, the vibration applying unit 1020 starts to vibrate.

  2B to 2D are views showing a state where vibration is applied to the mesh member 120 by the vibration applying unit 1020. FIG. In FIG. 2B, the mesh member 120 is displaced outward, and the liquid 130 is pulled outward due to the surface tension. In FIG. 2 (C), the mesh member 120 is again displaced so that the internal pressure of the liquid container 112 is increased, and the liquid 130 is pushed out. In FIG. 2D, the mesh member 120 is displaced inward, and the extruded liquid 130 is ejected into a spherical shape due to surface tension. By repeatedly applying vibration to the mesh member 120 by the vibration applying unit 1020 such as a piezoelectric element, mist can be generated continuously.

(Container with mesh)
Next, the container with a mesh which comprises the liquid cartridge with which a spray device is mounted | worn is demonstrated using FIG.

  As shown in FIG. 3, the mesh-equipped container 10 includes at least a container part 110 and a mesh member 120. More specifically, the mesh-equipped container 10 is disposed on one end side of the container portion 110 so as to cover the opening of the liquid storage portion 112 and a container portion 110 having a liquid storage portion 112 that is open at one end. And a mesh member 120 in which holes 122 are formed. Further, the plurality of through holes 122 of the mesh member 120 are located in a region (opening region 113) where the opening of the liquid storage unit 112 exists.

A. The container section container section 110 includes a liquid storage section 112 that is an inner chamber capable of storing the liquid 130. One end of the liquid storage portion 112 is opened, and the liquid 130 held in the liquid storage portion 112 is guided out of the container portion 110 through the opening. The container part 110 has a flange part 114 provided on the outer periphery of the liquid storage part 112, and the container part 110 and the mesh member 120 are joined via the flange part 114. Although there is no restriction | limiting in the material of the container part 110, For example, resin, such as polyethylene terephthalate (PET), polycarbonate (PC), and polystyrene (PS), semiconductors, such as glass and silicon, metals, such as aluminum, etc., or these laminated bodies Etc. can be used. When the material is resin, it can be manufactured by a known method such as injection molding or thermoforming. When the material is glass, semiconductor, metal, etc., machining, MEMS (Micro Electro Mechanical Systems) ) It can be produced by a known method such as a processing technique. Especially, when using disposable, it is preferable to use resin from a viewpoint of cost and productivity.

B. Mesh member Mesh member 120 is disposed on one end side of container portion 110 so as to cover the opening of liquid storage portion 112. A large number of through holes 122 are formed in the mesh member 120, and the large number of through holes 122 are located in a region where the opening of the liquid storage portion 112 exists (opening region 113). Although there is no restriction | limiting in the material of the mesh member 120, For example, it can be set as the single layer or these laminated body of a polyethylene terephthalate (PET), a polycarbonate (PC), a polystyrene (PS), and a polypropylene (PP). There is no restriction | limiting in the thickness of the mesh member 120, It is good to set so that suitable rigidity may be acquired according to a material. For example, specific numerical values may be set in a range of 10 μm to 10 mm.

The size of the opening of the through-hole 122 can be appropriately set according to the degree of classification, and for example, it may be in the range of 1 to 50 μm. For example, when the lotion is atomized and diffused as a mist, the effect of penetrating the skin can be enhanced by setting the above numerical range. The sizes of the through holes 122 may be uniform, or the sizes of the holes may be non-uniform. The number of through holes 122 and the density of the through holes 122 are not limited, but may be in the range of 10 to 500 holes / mm ² , for example. In addition, the planar shape of the through hole 122 may be a polygon, an ellipse, or the like in addition to a circle. Further, the size of the opening of the through hole 122 may be the same on the front surface and the back surface of the mesh member 120 or may be different from each other.

  The material and thickness of the mesh member 120, the shape of the through-hole 122, and the like may be determined by the viscosity of the liquid 130 stored in the liquid storage unit 112. For example, when the viscosity of the liquid 130 is high, it is preferable to make the material of the mesh member 120 softer, reduce the thickness, and / or increase the diameter of the through-hole 122 than when the viscosity of the liquid 130 is low. However, since the material becomes soft, vibrations in the mesh are likely to be reduced, or the diameter of the through hole 122 may increase due to the fixing of the mesh member 120 according to the present invention. For this reason, it is preferable to set the diameter of the through-hole 122 in the range of 110-270%, more preferably 110-220%, for example, when the breaking elongation (tensile elongation) of the mesh member 120 is used as a guide.

  The mesh member 120 and the container 110 described above can be integrated by, for example, direct bonding or bonding with an adhesive. In the direct bonding, for example, when the mesh member 120 and the container part 110 are made of the same material resin, the two can be bonded using an ultrasonic fusion method. In joining with an adhesive, an appropriate adhesive may be used in consideration of the material of the mesh member 120 and the material of the container part 110. For example, a heat sealant that melts by heating and solidifies by cooling may be used.

  Alternatively, the container unit 110 and the mesh member 120 may be configured separately in advance, and these may be joined when the container unit 110 and the mesh member 120 are attached to the spray device 1000. In this case, you may make it join the outer periphery of the flange part 114 of the container part 110, and the mesh member 120 by the fixing member which is not shown in figure at the spray device 1000 side, for example.

  In the present specification, of the mesh member 120, the surface on which the liquid 130 is sprayed (upper surface in FIG. 3) is referred to as the front surface, and the surface on the container 110 side (lower surface in FIG. 3) is referred to as the back surface.

  The mesh member 120 has a uniform thickness, but is not limited thereto. For example, in the mesh member 120, a region radially inward from a region where the vibration applying unit 1020 contacts may be a thin region, and a region radially outside the region where the vibration applying unit 1020 may contact may be a thick region.

  In addition, in this Embodiment, although the vibration provision part 1020 is provided in the spray device 1000 side, it is not restricted to this, You may provide in the container 10 (liquid cartridge 100) side with a mesh. For example, the vibration applying unit 1020 may be attached to the mesh member 120 with an adhesive, and the mesh member 120 and the vibration applying unit 1020 may be replaced as a unit.

(Liquid cartridge)
A liquid cartridge is configured by filling the liquid container of the mesh-equipped container with liquid. Hereinafter, the liquid cartridge will be described with reference to FIG.

  In FIG. 4, the liquid cartridge 100 is configured by filling the liquid 130 in the liquid container 112 of the mesh-equipped container 10 described above. Such a liquid cartridge 100 includes a container part 110 having a liquid storage part 112 and a mesh member 120 provided so as to cover an opening of the liquid storage part 112. The liquid container 112 stores a liquid 130. In addition, since it has already demonstrated about the structure of the container part 110 and the mesh member 120, detailed description is abbreviate | omitted here.

  As shown in FIG. 5, such a liquid cartridge 100 further includes a seal member 150 that seals the liquid 130 on the mesh member 120 in order to prevent deterioration of the filled liquid 130 and leakage to the outside. Is preferred. The seal member 150 is provided on the surface of the mesh member 120 so as to cover the through hole 122.

  For example, the seal member 150 is fixed to the mesh member 120 via an adhesive layer. Although there is no restriction | limiting in the material of the sealing member 150, For example, polyethylene terephthalate (PET), resin, such as nylon, metals, such as aluminum, or these laminated bodies can be used. There is no restriction | limiting in the thickness of the sealing member 150, For example, it is good also as the range of 10 micrometers-1 mm. The seal member 150 is preferably disposed so as to be peelable from the mesh member 120. As a method of joining the seal member 150 to the mesh member 120, a method of joining the seal member 150 to the mesh member 120 using a weak adhesive, a seal member 150 and the mesh member 120 using an adhesive such as a heat seal agent. There can be mentioned a method of controlling the adhesion area so that is partially adhered.

  Various methods of filling the liquid container 112 into the liquid container 112 of the mesh-equipped container 10 are conceivable. For example, after injecting the liquid 130 into the liquid storage part 112, the mesh member 120 is joined to the container part 110, or the other end (bottom surface) of the container part 110 is joined after the mesh member 120 is joined to the container part 110. For example, a method of injecting the liquid 130 from a side injection hole (not shown) and sealing the injection hole can be considered. The liquid 130 filled in the liquid container 112 of the mesh-equipped container 10 is not particularly limited as long as it is in a liquid state at the time of use, and examples thereof include skin lotion, medicine, and fragrance.

(Operation of this embodiment)
Next, the operation of the present embodiment having such a configuration will be described.

  First, the user opens a liquid cartridge package (not shown) and takes out the liquid cartridge 100. Next, the seal member 150 (FIG. 5) of the liquid cartridge 100 is peeled off from the mesh member 120. Thereby, the mesh member 120 of the liquid cartridge 100 is exposed to the outside.

  Subsequently, the user mounts the liquid cartridge 100 in the housing 1010 of the spray device 1000 (see FIG. 1). At this time, the liquid cartridge 100 is inserted from an insertion port (not shown) of the housing 1010. Further, the mesh member 120 of the liquid cartridge 100 is disposed at a position corresponding to the spray port 1015 of the housing 1010 so that the mesh member 120 contacts the vibration applying unit 1020.

  Next, when the user turns on an input unit 1040 such as a switch, the control unit 1050 supplies power from the power supply unit 1030 toward the vibration applying unit 1020. As a result, the vibration applying unit 1020 starts to vibrate. At this time, as described above (FIGS. 2A to 2D), the mesh member 120 is vibrated by the vibration applying unit 1020, and the mist-like liquid 130 is sprayed from the through hole 122 of the mesh member 120.

During this time, the control unit 1050, as shown in FIG. 6 (A), so as to perform alternately a low-frequency step _{S 1} and the high frequency stage _{S 2,} and supplies power to the vibration applying unit 1020. Incidentally, FIG. 6 (A) is a schematic diagram showing in performing the low-frequency stages S ₁ and high frequency step S ₂ alternately, the ultrasonic vibration of the vibration applying unit 1020. In FIG. 6A, the vertical axis indicates the amplitude of the vibration applying unit 1020, and the horizontal axis indicates time.

Among these, the low frequency stage S ₁ is mainly penetrated when the liquid 130 has a high viscosity (for example, 1.5 × 10 ^{−3 to} 3.0 × 10 ⁻³ Pa · s in the vicinity of room temperature of 20 to 30 ° C.). In this step, the liquid 130 is sprayed from the holes 122. In the low frequency stage _{S 1,} the vibration applying unit 1020 is such that ultrasonic vibrations at a first frequency _{f 1} of predetermined, vibrating unit 1020 is controlled.

On the other hand, if the high frequency stage _{S 2} is mainly liquid 130 is a low viscosity (e.g. at around room temperature of ^{20~30 ℃ 0.8 × 10 -3 ~1.5 ×} 10 -3 Pa · s), the through-hole This is a step of spraying the liquid 130 from 122. In the high frequency stage _{S 2,} the vibration applying unit 1020 so that the ultrasonic vibrations at a predetermined second frequency _f 2 (> _{f 1),} the vibration applying unit 1020 is controlled.

Note that in both the low frequency phase S ₁ and high frequency step S _2, the frequency of the mesh member 120 is vibrated by the vibration applying unit 1020, the vibration applying unit 1020 itself is substantially the same as the frequency of ultrasonic vibration.

For example, when the liquid 130 has a high viscosity, in the low frequency stage S ₁ , the mesh member 120 is vibrated by the vibration applying unit 1020 and the mist-like liquid 130 is sprayed from the through hole 122. On the other hand, in the high frequency step S _2, due to the high viscosity of the liquid 130, the liquid 130 is less likely to be sprayed, but during this period, (see arrows in FIG. 7) that the liquid 130 is reliably replenished to the rear surface of the through hole 122. Therefore, when the next low frequency stages S _1, it is possible to spray the liquid 130 smoothly through the through hole 122.

In contrast, when the liquid 130 is a low viscosity, in the high frequency step _{S 2,} the mesh member 120 is vibrated by the vibration applying unit 1020, a mist-like liquid 130 is sprayed from the through hole 122. On the other hand, in the low-frequency stage S _1, due to the low viscosity of the liquid 130, the liquid 130 is less likely to be sprayed, but during this period, (see arrows in FIG. 7) that the liquid 130 is reliably replenished to the rear surface of the through hole 122. Thus, where the next frequency step S _2, it is possible to spray the liquid 130 smoothly through the through hole 122.

The first frequency _{f 1} is preferably set to a constant value to be included within the scope of 50KHz～140kHz. In particular, the first frequency f ₁ is preferably matched with the resonance frequency of the predetermined mesh member 120 corresponding to the high-viscosity liquid 130. The second frequency _{f 2} is preferably set to a constant value to be included within the scope of 110KHz～200kHz. In particular, the second frequency f ₂ is preferably matched with the resonance frequency of the predetermined mesh member 120 corresponding to the low-viscosity liquid 130.

In the above description, the ranges that the first frequency f ₁ and the second frequency f ₂ can take seem to overlap, but the frequencies are not overlapped in order to use liquids having different viscosities. Depending on the diameter of the material and the through hole 122 of the mesh member 120, the second frequency _{f 2} preferably higher than 1kHz than the first frequency _{f 1,} and even more preferably higher than 10 kHz. For example, when the first frequency f ₁ is 130 kHz, the second frequency f ₂ takes a value of 131 kHz or more, more preferably 140 kHz or more. As described above, by increasing the difference between the second frequency f ₂ and the first frequency f ₁ , it is possible to use liquids of various viscosities as the liquid 130 accommodated in the liquid cartridge 100.

Furthermore, as shown in FIG. 6 (A), each low frequency stage S ₁ is performed respectively by a fixed time T _1, the radio frequency stage S ₂ is executed respectively by a fixed time T _2. At this time, the low frequency phase length of time T ₁ that S ₁ is executed, it is preferred that each frequency step S ₂ is less than the length of the time is executed _{T 2 (T 1 ≦ T 2} ). The reason is as follows. That is, when the low-viscosity liquid 130 and the high-viscosity liquid 130 are compared, the time required for filling the same space is shorter for the low-viscosity liquid 130. Further, as described above, the low-viscosity liquid 130 is filled in the back surface of the through-hole 122 during the low-frequency stage S ₁ , and the high-viscosity liquid 130 is filled in the back surface of the through-hole 122 during the high-frequency stage S _2. Is done. Therefore, by setting the time T ₁ of the low frequency stage S ₁ to be shorter than the time T ₂ of the high frequency stage S ₂ , the liquid 130 is formed on the back surface of the through hole 122 regardless of whether the liquid 130 has a high viscosity or a low viscosity. It is because it can be filled appropriately.

Further, the voltage V _{1 of} power supplied from the control unit 1050 to the vibration applying unit 1020 at the low frequency stage S ₁ , and the voltage V _{2 of} power supplied from the control unit 1050 to the vibration applying unit 1020 at the high frequency stage S ₂ May be different.

For example, the voltage V ₁ at the low frequency stage S ₁ may be higher than the voltage V ₂ at the high frequency stage S ₂ . In this case, the amplitude of the vibration applying unit 1020 in a low frequency stage _{S 1} is larger than the amplitude of the vibration applying unit 1020 in the RF stage _{S 2.} Thus, in the low frequency stage S _1, since the mesh member 120 is swung greatly, it can be easy to be more spraying liquid 130 of high viscosity. In the high frequency stage S _2, since the mesh member 120 is swung small, it can be easy to be more spraying liquid 130 of low viscosity. In this case, the the voltages _{V 1} for example 5V to 10V, the voltage _{V 2} is preferably, for example, 3V and 8V.

Alternatively, it may be lower than the voltage _{V 2} to voltages _{V 1} in the low-frequency stage _{S 1} in the high-frequency stage _{S 2.} In this case, the amplitude of the vibration applying unit 1020 in a low frequency stage _{S 1} is smaller than the amplitude of the vibration applying unit 1020 in the RF stage _{S 2.} Accordingly, since the mesh member 120 is shaken small in the low frequency stage S ₁ , it becomes easy to fill the back surface of the through-hole 122 with the low-viscosity liquid 130. In addition, since the mesh member 120 is greatly shaken in the high frequency stage S ₂ , it becomes easy to fill the back surface of the through-hole 122 with the high-viscosity liquid 130. In this case, the the voltages _{V 1} for example 3V and 8V, voltage _{V 2} is preferably, for example, 1V to 5V.

As in the case of the frequency, the ranges that the voltage can take are also overlapped. However, in order to use liquids having different viscosities, there is no overlap. In each of the above cases, the difference between the voltage V ₁ and the voltage V ₂ is preferably 1 V or more. As described above, by increasing the difference between the voltage V ₁ and the voltage V ₂ , the liquid 130 having various viscosities can be effectively sprayed.

  In FIG. 6A, the vibration applying unit 1020 performs ultrasonic vibration using two different frequencies alternately. However, the present invention is not limited to this, and three or more different frequencies may be used repeatedly. .

Further, as shown in FIG. 6B, a zero frequency stage S ₀ that does not supply power from the control unit 1050 to the vibration applying unit 1020 is provided between the low frequency stage S ₁ and the high frequency stage S _2. Also good. In the zero frequency stage S ₀ , no ultrasonic vibration is applied from the vibration applying unit 1020 to the mesh member 120. Each zero-frequency phase S ₀ is executed by a predetermined time T _0. The length of this time T ₀ is shorter than the length of time T ₁ when each low frequency stage S ₁ is executed (T ₀ <T ₁ ), and from the length of time T ₂ when each high frequency stage S ₂ is executed. Short (T ₀ <T ₂ ) is preferred. In this case, the liquid 130 can be surely filled in the back surface of the through hole 122 in the zero frequency stage S ₀ , so that the liquid 130 can be smoothly discharged from the through hole 122 in the subsequent low frequency stage S ₁ or high frequency stage S ₂ . Can be sprayed. In the zero frequency stage S ₀ , the power is smaller than the power supplied from the control unit 1050 to the vibration applying unit 1020 in the low frequency stage S ₁ and the high frequency stage S ₂ and the mesh member 120 does not vibrate properly. Power may be supplied.

  After the liquid 130 is sprayed from the through hole 122 of the mesh member 120 in this way, when the liquid 130 of the liquid storage unit 112 becomes empty, the user turns off the input unit 1040. As a result, the power supplied from the power supply unit 1030 to the vibration applying unit 1020 is stopped, and the vibration of the mesh member 120 is stopped. In addition, a user may stop driving | running | working after predetermined time progress by the timer mechanism incorporated in the spraying device 1000, without transmitting the signal of OFF to the input part 1040.

  Next, the user takes out the empty liquid cartridge 100 (mesh container 10) from the casing 1010 of the spray device 1000 and discards it. Subsequently, the user installs a new liquid cartridge 100 (for example, a liquid cartridge 100 having a different viscosity of the contained liquid 130) in the casing 1010 of the spray device 1000 as necessary, and continues to use the spray device 1000. To do.

According to the present embodiment, the control unit 1050, the vibration applying unit 1020, a low-frequency step S ₁ that the frequency of the ultrasonic vibration of the vibration applying unit 1020 has a first frequency f ₁ of the predetermined vibration Electric power is supplied to the vibration applying unit 1020 such that the ultrasonic vibration frequency of the applying unit 1020 is alternately executed with the high frequency stage S ₂ having the second frequency f ₂ (> f ₁ ). Thereby, even when the mesh member 120 (liquid cartridge 100) is replaced with a different type, the liquid 130 can be reliably sprayed, so that convenience is enhanced.

  In particular, even when the viscosity of the liquid 130 stored in the liquid storage unit 112 is different, the spray device 1000 can be used as it is without adjusting various setting values on the spray device 1000 side. Therefore, there is no possibility that the configuration of the spray device 1000 becomes complicated, and an increase in the cost of the spray device 1000 can be suppressed. Further, when the spray device 1000 is replaced, it is not necessary for the user to perform complicated operations on the spray device 1000.
