Description

  The present invention relates to a sprayer for spraying mist, and is particularly suitable for use in a sprayer of a type in which air is introduced to suck up the spray liquid and the mist is formed for spraying.

  BACKGROUND ART In recent years, sprayers (so-called diffusers) for forming a spray liquid having an aromatic component such as aromatic oil into a mist and spraying it as a mist have become widespread. Not only stationary-type sprayers, but also portable mobile-type sprayers are in widespread use. The mobile type simply means that it is small enough to be carried and can be used in the brought-in space. Mobile-type sprayers are used, for example, by bringing them into the car.

  There are various ways in which the sprayer sprays the mist. For example, there is a method of generating and spraying a mist by vibrating a liquid by an ultrasonic wave, and a method of generating and spraying a mist by a mist nozzle in which a fine spray hole is formed. Besides this, as a method of spraying the mist, a method of introducing air and sucking up the spray liquid by the Venturi effect, forming it into mist and spraying (hereinafter referred to as "corresponding method") is known (for example, Patent Document 1) reference).

  The sprayer described in Patent Document 1 includes a reservoir, an inner pipe, an outer pipe, a lid, and a separation plate (upper separation plate). The atomizer described in Patent Document 1 introduces a liquid flow path formed between an inner pipe and an outer pipe by using an air pump to introduce compressed air into the air supply path of the inner pipe to store the spray liquid stored in the storage tank. Mist is generated in the space between the tip of the inner pipe and the tip of the outer pipe by compressed air that is sucked up and discharged from the air supply port of the inner pipe, and the generated mist is separated from the mist outlet of the outer pipe Spray towards the plate. And the spraying device of patent document 1 isolate | separates coarse mist and fine mist with a separating plate, and sprays only fine mist outside the main body through the mist discharge hole of a cover part. In addition, in the sprayer which sprays mist by a corresponding method like the sprayer of patent document 1, since it is necessary to secure the space between the tip part of an inner pipe and the tip part of an outer pipe, it stores in a storage tank. It is necessary that the liquid level of the liquid to be sprayed be located below the tip (air supply port) of the inner pipe.

Patent No. 599 1 685

  Consider now that the mobile-type sprayer is constituted by a sprayer of the type that sprays the mist in a corresponding manner. The mobile type sprayer prevents the frequent occurrence of the operation of supplying the spray liquid at the carry-on destination of the sprayer, so the period for which the mist is continuously sprayed without performing the operation of supplying the spray liquid is as long as possible. It is required to be timed. In particular, when the sprayer is used by bringing it into the vehicle, since the driver can not replenish the sprayer with the spray liquid while driving the vehicle, the period in which the mist is continuously sprayed is extended. It is strongly demanded that the shortage of the spray liquid not occur during the operation. Furthermore, the mobile type sprayer is able to control the volume and pressure of the wind output by the air pump necessary for driving (hereinafter, the combination of the volume and pressure of the wind output by the air pump is referred to as “output volume” for convenience) It is required to be small. If it is possible to drive with a small output air volume, an air pump having a small output can be used, and power saving and downsizing of the sprayer can be realized. Note that the mobile sprayer is usually mounted with a battery, not a commercial power supply, and receives power supply from the battery, or saves power because it receives power supply from an external battery at the place brought in. Is strongly required.

  In a sprayer of the type that sprays mist in a corresponding way, if the lengths of the inner and outer pipes are shortened, the length of the liquid flow path formed between the outer circumference of the inner pipe and the inner circumference of the outer pipe is short As a result, the output air volume of the air pump can be small, power saving of the sprayer, and downsizing of the sprayer with downsizing of the air pump can be realized. However, as described above, in the sprayer of the type that sprays the mist by the corresponding method, the liquid level of the spray liquid stored in the storage tank needs to be located below the tip (air supply port) of the inner pipe Therefore, as the lengths of the inner pipe and the outer pipe are shortened, the maximum amount of the spray liquid that can be stored in the storage tank becomes smaller, and the prolongation of the mist spraying period is inhibited. Conversely, if the lengths of the inner and outer pipes are increased and the maximum amount of spray liquid that can be stored in the storage tank is increased for the purpose of extending the mist spraying period, the reduction in the output air volume of the air pump is inhibited. It will

  The present invention has been made to solve these problems, and it is an extension of the mist spraying period for a type of sprayer that introduces air and sucks up the spray liquid, and atomizes and sprays it, and The purpose of the present invention is to simultaneously reduce the output air volume of the air pump.

  In order to solve the problems described above, the sprayer of the present invention is formed in a housing and a housing, and a storage tank capable of storing a spray liquid is formed in the inside of the storage chamber and the upper opening of the storage chamber is closed. A lid formed with a mist release hole, an inner pipe provided in a storage chamber and having an air supply port for discharging air at the tip end, an air pump for supplying air to the inner pipe, a liquid flow path to the inner pipe An outer tube having a gap and being extrapolated to form a mist jet at the tip and a liquid suction opening at the proximal end, and between the lid and the outer tube, the outer tube A spray unit having a separation plate provided at a position facing the mist sprayer, a storage chamber which is formed in a housing and in which a space capable of storing a container for storing a spray liquid is formed, and The spray liquid is supplied from a container provided below the chamber and stored in the storage chamber, and supplied from the container. A liquid supply unit having a temporary storage unit for temporarily storing the spray liquid, and an introduction path provided in the housing for introducing the spray liquid stored in the temporary storage unit into the storage chamber, According to the supply of the spray liquid from the container to the temporary storage section, the spray liquid is introduced from the temporary storage section into the storage chamber via the introduction path, and the liquid surface of the spray liquid stored in the temporary storage section The liquid level of the stored spray liquid is integrally raised at the same position, and the position of the liquid level of the spray liquid stored in the storage chamber is the same regardless of the remaining amount of the spray liquid stored in the container. When the temperature is lower than the predetermined position, the supply of the spray liquid from the container is stopped, and the rising of the liquid level is stopped.

  According to the present invention configured as described above, the liquid supply unit is provided separately from the spray unit, and the spray liquid is supplied from the container stored in the storage chamber of the liquid supply unit to the storage tank of the spray unit. Therefore, the maximum amount of spray liquid that can be stored in the container is the maximum amount of spray liquid that can be used by the spray unit, and it is possible to realize a longer mist spraying period. In addition, in the case of a type of sprayer that introduces air and sucks up the spray liquid, and atomizes and sprays the mist, the liquid level of the spray liquid in the storage chamber is always located lower than the tip of the inner pipe. According to the present invention configured as described above, the position of the liquid surface of the spray liquid in the storage chamber does not exceed the predetermined position regardless of the remaining amount of spray liquid remaining in the container. The lengths of the inner pipe and the outer pipe may be set so that the height of the tip of the inner pipe is above the predetermined position, and the lengths of the inner pipe and the outer pipe can be shortened. And by shortening the length of the outer pipe, it is possible to realize a reduction in the output air volume of the air pump.

  As described above, the outer peripheral shape of the upper end opening 4 (upper end region) of the housing 2 has three sides H (side HA, side HB and side HC) of the same length, and three arc-shaped connecting portions T (connections It is a number corresponding shape having a part TA, a connection part TB and a connection part TC). As shown in FIG. 1A, in the installation stand 6, the three spray units 10 are arranged at positions corresponding to the three connection portions T, respectively. More specifically, the three spray units 10 are arranged in the vicinity of each of the three connection portions T, respectively, in a state of being separated by the same angle (120 °) on the imaginary circle KS1. Due to such a configuration, each of the three spray units 10 can be efficiently spaced apart from the installation stand 6.

  Further, the sprayer 1 according to the present embodiment can spray three types of mists, but the outer peripheral shape of the upper end region is a number corresponding shape having the same number of connection portions T as the number of types of sprayable mists. Therefore, in the upper end portion of the housing 2, the number of portions (connecting portions T) overhanging outward matches the number of types of mist that can be sprayed. As a result, the appearance of the sprayer 1 can be related to the number of types of mist that can be sprayed, and the appearance of the sprayer 1 can be made into an appearance that utilizes the characteristic that three types of mist can be sprayed. Can. Thereby, the user can intuitively recognize the types and the number of mists that can be sprayed simply by looking at the appearance of the sprayer 1, and the convenience of the user is high. In particular, in the sprayer 1 according to the present embodiment, since each spray unit 10 is provided in the vicinity of each connection portion T, the user only looks at the appearance of the sprayer 1 and the position where mist is sprayed in the sprayer 1 Intuitively.

A storage room side connection unit 51, which is a connection unit between the introduction path 21 and the temporary storage unit 46, is connected to the lower end of the temporary storage unit 46. Further, the storage tank side connection part 52, which is a connection part between the introduction path 21 and the storage tank room 20, is positioned above the liquid suction port 54 (described later) of the outer pipe 53 provided in the storage tank room 20. .

  Under the above configuration, when the container 17 is stored in the storage chamber 16 (when the container 17 is attached to the holding mechanism 48), the spray liquid stored in the container 17 is supplied to the storage chamber 20 in the following manner. . That is, when the container 17 in which the spray liquid is sufficiently stored is screwed to the holding mechanism 48 in a state upside down, the spray liquid stored in the container 17 is temporarily stored little by little via the liquid supply port 45 of the pipe 44 It is supplied to the part 46. As described above, since the storage room side connection unit 51 is located at the lower end portion of the temporary storage unit 46, the spray liquid supplied to the temporary storage unit 46 first passes through the introduction path 21. , Introduced into the storage chamber 20 and stored in the storage chamber 20. Further, in the container 17, a sealed space 55 (see FIG. 6) is formed above the liquid level of the spray liquid remaining in the container 17.

  As the supply of the spray liquid from the container 17 to the temporary storage unit 46 progresses, the water level of the spray liquid stored in the storage tank chamber 20 gradually rises, and the liquid level in the storage tank chamber 20 moves upward from the bottom surface of the temporary storage section 46 Overrun. After this state, since the temporary storage unit 46 and the storage chamber 20 are connected via the introduction path 21, the height of the liquid surface in the storage chamber 20 and the height of the liquid surface in the temporary storage unit 46 , And in response to the supply of the liquid from the container 17, the liquid levels are integrally raised while maintaining the same height of the liquid levels. In response to the rise of the liquid level in the temporary storage unit 46, the liquid supply port 45 of the pipe 44 of the container 17 is immersed in the spray liquid stored in the temporary storage unit 46. When the liquid level continues to rise according to the supply of the spray liquid from the container 17, the liquid level rising stops at a certain position.

  FIG. 6 is a view schematically showing the state of the spray liquid when the rise of the liquid level is stopped in FIG. As described above, the internal space of the temporary storage portion 46 is a space opened to the atmospheric pressure, and the storage chamber 20 is also a space communicating with the mist release hole 26 formed in the lid portion 24. It is a space open to atmospheric pressure. Therefore, atmospheric pressure acts on the liquid surface of the temporary storage unit 46 and the storage chamber 20. Then, in the container 17, the atmospheric pressure acting on the liquid surface of the temporary storage unit 46 and the storage tank chamber 20 and “on the liquid surface derived from the spray liquid staying above the liquid surface inside the container 17 When the pressure and the pressure acting on the liquid surface due to the air layer staying in the sealed space 55 of the container 17 are balanced, the rise of the liquid surface in the storage chamber 20 and the temporary storage unit 46 stops, and the storage tank In the situation where there is no consumption of the spray stored in the chamber 20, the supply of the spray from the container 17 is stopped.

  As described above, after the container 17 is stored in the storage chamber 16, the liquid level in the temporary storage unit 46 and the storage chamber 20 integrally rises in response to the supply of the spray liquid from the container 17 for a while. When the pressure balance related to the air pressure is balanced, the rise of the liquid level is stopped and the supply of the spray liquid from the container 17 is stopped. And, in the present embodiment, regardless of the remaining amount of the spray liquid stored in the container 17, the position of the liquid surface of the spray liquid stored in the storage chamber 20 is higher than the position P2 in the storage chamber 20 (see FIG. 6). When in the low state, the pressure balance related to the atmospheric pressure is balanced, the rise of the liquid level is stopped, and the supply of the spray liquid from the container 17 is stopped. That is, in this embodiment, regardless of the remaining amount of the spray liquid stored in the container 17, the position of the liquid level in the storage chamber 20 is always positioned lower than the position P2. The position P2 is set to a lower position in the storage chamber 20 after satisfying the condition that the position is higher than the liquid suction port 54 of the outer pipe 53. Specifically, when the length of the storage chamber 20 in the vertical direction is “1”, the position is lower than the position “1/3” above the bottom surface of the storage chamber 20. The effects based on the above configuration will be described later.

  When consumption of the spray liquid by the spray unit 10 proceeds, the container 17 eventually becomes empty. As described above, the introduction path 21 is inclined downward toward the storage chamber 20 from the temporary storage section 46, and the storage chamber side connection which is a connection portion between the introduction path 21 and the storage chamber 20. The portion 52 is located above the liquid suction port 54 of the outer tube 53 provided in the storage chamber 20. For this reason, when consumption of the spray liquid by the spray unit 10 further progresses after the container 17 becomes empty, first, the temporary storage section 46 becomes empty, and thereafter, the storage tank chamber 20 becomes empty. With such a configuration, when the spray liquid does not remain in the storage chamber 20 and the mist can not be sprayed by the spray unit 10, the liquid is prevented from remaining in the temporary storage section 46. Can do it.

  In addition, for example, regardless of the remaining amount of the spray liquid stored in the container 17, it is possible to make the upper limit position of the liquid surface in the storage tank chamber 20 lower than the position P2 by adopting the following configuration. That is, the storage chamber 20 is provided with a sensor that detects the position of the liquid level. Further, the liquid supply port 45 of the container 17 and the storage chamber 20 are connected by a flow path, and a pump is provided on this flow path, and the spray liquid is supplied from the container 17 to the storage chamber 20 while the pump is driven. The supply of the spray liquid from the container 17 to the storage chamber 20 is stopped while the pump is stopped. Then, the position of the liquid surface of the sensor is managed based on the detection value of the sensor, and the drive of the pump is controlled so that the position of the liquid surface does not exceed the position P2 upward, It is possible to make the upper limit position of the liquid level in the storage chamber 20 lower than the position P2 regardless of the remaining amount of the spray liquid to be stored. However, in this case, it is necessary to provide a sensor and a pump, which results in an increase in manufacturing cost, a complicated apparatus structure, an increase in power consumption, and an increase in size of the housing 2. On the other hand, according to the present embodiment, the upper limit position of the liquid surface in the storage chamber 20 is made lower than the position P2 due to the balance of pressure balance related to the atmospheric pressure. Does not occur.

  Further, in the present embodiment, when the container 17 is attached to the holding mechanism 48, the spray liquid is automatically supplied to the storage chamber 20 via the temporary storage portion 46, so that the spray liquid to the storage chamber 20 is At the time of supply, the user does not have to perform a special operation other than attaching the container 17, and the convenience of the user is high.

  As shown in FIG. 5, the spray unit 10 has an inner pipe 56. The inner pipe 56 is erected at the central portion of the storage chamber 20 in a state of penetrating the bottom surface of the storage chamber 20. An air supply passage 57 is formed in the inner pipe 56, and a lower end portion of the air supply passage 57 is connected to an air supply passage (not shown) to which compressed air is supplied from the air pump 11. The compressed air discharged by the air pump 11 is introduced into the air supply passage 57 of the inner pipe 56. An air inlet 58 communicating with the air supply passage 57 is provided at the tip of the inner pipe 56.

  The outer pipe 53 is encased in the inner pipe 56 in a state in which a gap to be the liquid flow path 59 through which the spray liquid flows is formed. The width of the liquid channel 59 is about 1 to 2 mm. The outer pipe 53 is formed in a hollow cylindrical shape into which the inner pipe 56 can be inserted, and its position is fixed in a state where the position in the storage chamber 20 is positioned by a predetermined mechanism. A mist jet port 60 communicating with the liquid flow path 59 is formed at the tip of the outer pipe 53, and a liquid suction port 54 is formed at the proximal end of the outer pipe 53. As shown in FIG. 5, the liquid suction port 54 is exposed to the storage tank chamber 20 at the lowermost end of the storage tank chamber 20, and when the spray liquid is stored in the storage tank chamber 20, the spray liquid is It is introduced into the outer tube 53 through the suction port 54. As shown in FIG. 5, an outer pipe space 61 which is a space is formed between the air supply port 58 of the inner pipe 56 and the mist jet port 60 of the outer pipe 53.

  As described above, the lid portion 24 is a lid member that covers the upper end opening of the storage tank chamber 20, is provided with the mist discharge hole 26 through which the mist generated in the storage tank chamber 20 passes, and communicates with the mist discharge hole 26 A spray port 39 for spraying is provided. A separation plate 33 is provided between the lid 24 and the outer pipe 53 at a position where the mist jet port 60 of the outer pipe 53 faces. On the lower surface of the separation plate 33, a curved curved surface 33a curved so as to be recessed upward is formed.

  Under the above configuration, the spray unit 10 sprays mist in the following manner. In the following description, it is assumed that the container 17 in which the spray liquid sufficiently remains is stored in the storage chamber 16. When spraying mist, first, the air pump 11 is driven, and compressed air is introduced from the air pump 11 into the air supply path 57 of the inner pipe 56. The compressed air introduced into the air supply passage 57 of the inner pipe 56 is discharged upward from the air supply port 58, and is further discharged into the storage chamber 20 through the mist jet port 60 of the outer pipe 53. At this time, when the compressed air is discharged from the mist jet port 60, the outer pipe space 61 between the air supply port 58 of the inner pipe 56 and the mist jet port 60 of the outer pipe 53 has a negative pressure. As a result, the spray liquid that has entered the outer pipe 53 from the liquid suction port 54 of the outer pipe 53 is sucked upward through the liquid flow path 59 (see arrow Y2 in FIG. 5), and the upper opening of the air supply port 58. A liquid film is formed along the surface, which is torn off by the air discharged from the air supply port 58 of the inner pipe 56 to form a primary mist.

  The primary mist ejected into the outer pipe space 61 in this manner collides with the inner peripheral wall surface of the outer pipe 53, and is torn off by the impact and the shear of the air flow due to the orifice effect, and a finer secondary mist is generated. Be done. The secondary mist is jetted from the mist jet port 60 of the outer pipe 53 to the storage chamber 20 (see arrow Y3 in FIG. 5). The secondary mist spouted upward from the mist spout 60 collides with the curving surface 33 a of the separation plate 33 provided above the mist spout 60. Here, the mist having a large particle diameter (hereinafter referred to as “coarse mist”) is reflected downward because of large inertia force, and is returned to the spray stored in the storage chamber 20 (see arrow Y 4 in FIG. 5). As described above, the coarse mist quickly circulates to the spray liquid stored in the storage chamber 20 without touching the air outside the storage chamber 20. For this reason, the oxidation promotion of the spray liquid stored in the storage chamber 20 is suppressed.

  On the other hand, mist having a fine particle diameter not returned to the spray liquid stored in the storage chamber 20 (hereinafter referred to as "fine mist") has a small inertial force, and therefore it collides with the curving surface 33a of the separation plate 33 It does not bounce back, but it gets on the air flow and spreads horizontally beyond the edge of the separating plate 33 (see arrow Y5 in FIG. 5). The fine mist diffused in the horizontal direction beyond the edge of the separation plate 33 is carried by the air flow and flows into the mist discharge hole 26 of the lid 24 and passes through the mist discharge hole 26 and sprayed from the spray port 39 to the outside of the system. Be done.

  Here, the sprayer 1 according to the present embodiment is a mobile type sprayer, and it is required that the output air volume of the air pump 11 necessary for driving is as small as possible. If the air pump 11 can be driven with a small output air volume, a small output can be used as the air pump 11, and power saving and downsizing of the sprayer 1 can be realized. In particular, since the sprayer 1 according to the present embodiment is not configured to be driven by receiving supply of power from a commercial power supply, power saving is strongly required. As described above, the sprayer 1 according to the present embodiment uses the Venturi effect by introducing compressed air from the air pump 11 to the inner pipe 56, and between the outer circumference of the inner pipe 56 and the inner circumference of the outer pipe 53. In order to suck up the spray liquid through the liquid flow path 59 formed in order to generate mist, the shorter the length of the inner pipe 56 and the outer pipe 53 and the shorter the length of the liquid flow path 59, the more the spray liquid is absorbed. Therefore, the output air volume of the air pump 11 can be reduced.

  Then, in the sprayer 1 according to the present embodiment, as described above, the upper limit position of the liquid surface in the storage chamber 20 is below the position P2, and the upper limit position of the liquid surface in the storage chamber 20 is low. That is, regardless of the amount of the spray liquid remaining in the container 17, the position of the liquid level in the storage chamber 20 is maintained at a low level below the position P2. Therefore, the inner tube 56 and the outer tube 53 can be used as long as the spray liquid can be sucked up and misted by the Venturi effect, and the tip of the inner tube 56 is positioned above the position P2. Thus, the output air volume of the air pump 11 can be reduced.

  Furthermore, since the sprayer 1 according to the present embodiment is a mobile type sprayer, the spray liquid is supplied in order to prevent the operation of supplying the spray liquid frequently occurring at the carry-on destination of the sprayer 1. It is required to prolong the time during which the mist is continuously sprayed without increasing the time as much as possible. An increase in the spray time can be achieved by increasing the maximum amount of spray liquid that can be consumed by the spray unit 10 in a single use. In the sprayer 1 according to the present embodiment, the liquid supply unit 18 is provided separately from the spray unit 10, and the container 17 stored in the storage chamber 16 of the liquid supply unit 18 is stored in the storage chamber 20 of the spray unit 10. A spray liquid is supplied. Therefore, regardless of the maximum amount of spray liquid that can be stored in the storage chamber 20, the maximum amount of spray liquid that can be stored in the container 17 is the maximum amount of spray liquid that can be used by the spray unit 10, and the mist spraying time Can be realized.

  Note that the increase in mist spraying time can be realized by increasing the maximum amount of spray liquid that can be stored in storage chamber 20 without providing liquid supply unit 18, but storage can be performed in storage chamber 20. In order to increase the maximum amount of the spray liquid, it is necessary to increase the length of the inner pipe 56 and the outer pipe 53, and the reduction of the output air volume of the air pump 11 is inhibited. On the other hand, in the present embodiment, the mist spraying time can be extended without increasing the length of the inner pipe 56 and the outer pipe 53, in other words, without increasing the output air volume of the air pump 11.

  Next, an example of usage of the sprayer 1 will be described. As described above, the sprayer 1 according to the present embodiment is a mobile type sprayer, and is used by bringing it into a predetermined space. However, the sprayer 1 according to the present embodiment is, in particular, the inside of the vehicle It is assumed to be brought into use for use. Hereinafter, the usage aspect of the sprayer 1 is demonstrated as a sprayer 1 being used by a vehicle. Also, it is assumed that the user is a person driving a vehicle.

  First, the user prepares, as the container 17, three containers 17 in which the following three types of spray liquids are stored. The first is a spray liquid having a drowsiness awakening effect, for example, a mint-based aroma oil containing peppermint essential oil. Hereinafter, the spray liquid having the effect of awakening drowsiness is referred to as "drowsiness awakening liquid", the container 17 storing the drowsiness awakening liquid is referred to as "drowsiness awakening container", and the mist based on the drowsiness awakening liquid is referred to as "drowsiness awakening mist" . The second is a spray having an effect of recovering fatigue, and is, for example, an aroma oil containing an essential oil derived from orange and citrus fruits of coconut palm. Hereinafter, the aroma oil having the effect of recovering fatigue is called "fatigue recovery liquid", the container 17 storing the fatigue recovery liquid is called "fatigue recovery container", and the mist based on the fatigue recovery liquid is called "fatigue recovery mist" . The third is a spray liquid having an effect of deodorizing the space where the sprayer 1 is provided. Hereinafter, the spray liquid having the deodorizing effect is referred to as "deodorant", the container 17 storing the deodorant as "deodorant container", and the mist based on the deodorant as "deodorant mist". The structure of the holding mechanism 48 of the liquid supply unit 18 and the size of the storage chamber 16 correspond to the shape of the widely-distributed and widely used container 17 for aromatherapy that is currently sold widely, and the user is By purchasing the container 17, the container 17 which concerns on said 3 types of spray liquids can be purchased. The provider of the sprayer 1 may provide a set of three containers 17 according to the above three types of spray liquids.

  The user brings the sprayer 1 and the three containers 17 into the vehicle and attaches the sprayer 1 to the holder. Hereinafter, the attachment of the sprayer 1 to the holder will be described together with the structural features of the sprayer 1. Here, in recent years, drink holders have become widespread. The drink holder is a member to which a cylindrical object such as a can of juice or a cup is attached and which supports the attached cylindrical object. Many vehicles already have drink holders in place, and such drink holders are sold by various means such as store sales and mail order, and users can easily obtain drink holders. be able to.

  FIG. 7 is a view showing an example of the drink holder. FIG. 7A is a view showing the drink holder 70 viewed from the side, together with the cylindrical object attached to the drink holder 70, and FIG. 7B is a view showing the drink holder 70 from above It is. It is assumed that the height of the cylindrical object shown in FIG. 7A is the same as the height of the sprayer 1 according to the present embodiment.

  The drink holder 70 illustrated in FIG. 7 is provided upright on the mounting table 71 on which the cylindrical object is mounted and the mounting table 71, and contacts the side surface of the object when the object is mounted. A restricting member 72 for restricting the movement of the object in the horizontal direction and the restricting member 72 attached thereto grip the object when the object is mounted, and press the object against the restricting member 72. And a pair of support portions 73 for positioning the position of the object relative to the mounting table 71. As shown in FIG. 7B, a curved surface 73a curved in an arc shape is formed in each of the pair of support portions 73, and the curved surface 73a contacts the side surface of the cylindrical object to form a cylindrical shape. To support the object and stably fix the cylindrical object. On the other hand, when an object with a triangular prism or a square prism is attached to the drink holder 70, the portion where the curved surface of the support portion 73 contacts is reduced, which is more stable than when a cylindrical object is attached. It will not be fixed to

  In the following description, it is assumed that the drink holder 70 illustrated in FIG. 7 is provided in advance in the vehicle. In addition, the drink holder 70 illustrated in FIG. 7 is an example of a drink holder to the last, and the drink holder of various shapes prevails under the present conditions. However, a drink holder of various shapes basically has a support portion for supporting a cylindrical object (for example, a bottomed cylindrical shape into which a cylindrical object is inserted, like the drink holder 70 illustrated in FIG. 7). The support portion is provided so that the cylindrical object can be stably supported by the support portion.

  The user mounts the sprayer 1 brought into the car into the drink holder 70. Here, as described above, the three-dimensional shape of the casing 2 of the sprayer 1 is a shape that gradually changes from a circle to a number-corresponding shape as going from the lower end region to the upper end region. For this reason, in the case 2, the three-dimensional shape of the range assumed to be in contact with the support portion of the drink holder 70 is a shape close to a cylinder. In the drink holder 7070 illustrated in FIG. 7, the vertical center of the sprayer 1 is gripped by the support portion 73, but each cross section of the range where the support portion 73 contacts is a shape close to a circle, and the support The three-dimensional shape of the range in which the portion 73 is in contact is a shape close to a cylinder. As described above, when the cylindrical object is mounted, the drink holder 70 stably supports the object, but in the sprayer 1 according to the present embodiment, it is assumed that the support portion of the drink holder 70 contacts. Since the three-dimensional shape of the range is a shape close to a cylinder, when the sprayer 1 is attached to the drink holder 70, it is stably supported by the support as in the case of attaching a cylindrical object.

  After the user mounts the sprayer 1 on the drink holder 70, the user stores the drowsiness recovery container, the fatigue recovery container, and the deodorization container in each of the storage chambers 16 of the sprayer 1. The attachment of the sprayer 1 to the drink holder 70 and the storage of the containers 17 in the storage chambers 16 may be performed back and forth. As described above, according to the storage of the container 17 in the storage chamber 16, the supply of the spray liquid from the container 17 to the storage chamber 20 is appropriately performed, and the mist spray can be started.

  Here, it is widely known that while driving a vehicle, the driver may experience a physical and psychological state of "sleepiness" or "fatigue". Sleepiness may occur, for example, when you are running out of sleep or when you are traveling for a considerable amount of time in a landscape with no light, and fatigue may, for example, be when you are driving a vehicle for a long time Occurs when frequent operation related operations occur. And the sprayer 1 which concerns on this embodiment can awaken the drowsiness which a driver produced, or can recover fatigue in the state in which the drowsiness awakening container, the fatigue recovery container, and the deodorizing container are stored. Act as a diffuser.

  More specifically, when the user feels sleepiness, the user operates the panel 13 to start spraying the drowsiness awakening mist based on the drowsiness awakening liquid. The drowsiness awakening mist is a mist including a component having an effect of awakening the drowsiness, and the drowsiness awakening mist is sprayed in the car, and the user is able to sniff the drowsiness awakening mist, thereby awakening the drowsiness of the user. Prompted. Similarly, when the user feels fatigue, the panel 13 is operated to start spraying of the fatigue recovery mist based on the fatigue recovery liquid. The fatigue recovery mist is a mist including a component having an effect of recovering fatigue, and the fatigue recovery mist is sprayed in the car, and the user can recover the user's fatigue by being in a state where the user can sniff the fatigue recovery mist. Be prompted

  Here, the timing at which the user starts spraying mist with the sprayer 1 in expectation of the effects of sleepiness awakening or fatigue recovery is often when the user is driving, and the sleepiness awakening or fatigue recovery according to the mist spraying The effect of is required to appear to the user as soon as possible. And in order for the effect of sleepiness awakening and fatigue recovery to appear to the user as soon as possible according to the mist spray, the mist having a fine particle diameter needs to be sprayed by a sufficient amount per unit time by the sprayer 1 . In addition, the effect of sleepiness awakening and fatigue recovery can be properly provided to the user if oxidation of mist sprayed does not proceed as much as possible.

  And as above-mentioned, the sprayer 1 which concerns on this embodiment introduce | transduces compressed air as a method of spraying mist, the method of sucking up a spray liquid by a Venturi effect, misting, and spraying (henceforth "the corresponding method" In addition, since only mist having a fine particle diameter is released out of the system by the separation plate 33, it is possible to spray a sufficient amount of mist having a fine particle diameter per unit time. In the sprayer 1 according to the present embodiment, the coarse mist is promptly returned to the spray liquid by the separation plate 33, so that the promotion of the oxidation of the spray liquid can be suppressed and the mist to which the oxidation has not advanced as much can be sprayed. .

  In addition, in the sprayer 1 according to the present embodiment, the power saving is realized along with the downsizing of the housing 2 and the reduction of the output air volume of the air pump 11 due to the above-described structural features. In terms of power consumption, it is very suitable as a sprayer 1 used in a vehicle. Here, the method of spraying the mist by the sprayer is, other than the corresponding method, a method of generating and spraying the mist by vibrating the liquid by an ultrasonic wave, and generating the mist by the mist nozzle in which the fine spray holes are formed. There is a method of spraying and the like. However, when it is intended to spray a fine mist sufficiently to the extent that sleepiness awakening and fatigue recovery effects equivalent to those of the sprayer 1 according to the present embodiment can be obtained by a method other than the corresponding method. It is extremely difficult with the same power consumption and the same small size as the sprayer 1 concerned.

  Further, as described above, in the present embodiment, in addition to the drowsiness awakening container and the fatigue recovery container, the deodorizing container for storing the deodorizing liquid is accommodated in the sprayer 1. The deodorizing mist based on the deodorizing liquid is sprayed, for example, in the following case. That is, when the effect of sleepiness awakening or fatigue recovery is obtained after spraying of drowsiness awakening mist or fatigue recovery mist, the user wants to quickly deodorize the interior of the vehicle and temporarily set a space without a specific smell. In such a case, the user causes the sprayer 1 to spray the deodorizing mist to deodorize the space in the vehicle. Moreover, a vehicle may not only be driven by a specific user, but may be driven by a different user. In particular, when a vehicle is used in a rental car or car sharing, basically, the vehicle is driven by an unspecified person. Then, after one user sprays mist using the sprayer 1 in the vehicle, when another user drives the vehicle in place of the one user, the other user once has a specific smell In such a case, the other user may cause the sprayer 1 to spray the deodorizing mist to deodorize the space in the vehicle.

  That is, the inside of the vehicle is a sealed narrow space, and it is assumed that the need to make the space in the vehicle odorless once it actually arises after the mist spray by the sprayer 1 is performed. And by accommodating the deodorizing container which stores the deodorizing liquid in the sprayer 1, such needs can be met exactly.

  Here, in the present embodiment, the sprayer 1 includes three storage chambers 16 and can store up to three containers 17. The larger the number of storage chambers 16, the larger the size of the sprayer 1. As mentioned above, while driving, the driver may experience physical and psychological states of "sleepiness" or "fatigue", but "sleepiness" and "fatigue" adversely affect the driving It is a typical symptom that occurs during driving in that it may occur, and there is a real need to at least alleviate these symptoms during driving. Further, as described above, the inside of the vehicle is a sealed narrow space, and there is a need to temporarily make the space in the vehicle odorless after the mist spray by the sprayer 1 is performed. And, since the sprayer 1 according to the present embodiment is provided with the minimum number (three) of storage chambers 16 necessary to satisfy the needs, the needs of the sprayer 1 can be reduced while the size of the sprayer 1 is reduced. It is possible to meet.

  As mentioned above, although an example of a use mode of spray machine 1 was explained, it is needless to say that a use mode of spray machine 1 is not limited to the illustrated mode. For example, the place where the sprayer 1 is used is not limited to the inside of the vehicle, and may be, for example, a room in a house. Moreover, the container 17 accommodated in the sprayer 1 can accommodate not only the sleepy awakening container, the fatigue recovery container, and the deodorizing container illustrated, but also the container 17 relating to various types of spray liquids. In particular, in the present embodiment, mists based on a plurality of (two to three) different types of spray liquids can be simultaneously sprayed, and the mist can be jetted out in such a manner to enjoy the scent.

<Modification>
Next, a modification is described. In the embodiment described above, the outer peripheral shape of the upper end region of the housing 2 is a shape having three sides H and three connecting portions T of the same length. In this regard, the outer peripheral shape of the upper end region of the housing 2 is not limited to the shape according to the above-described embodiment. For example, in the case of having M (where M is an integer of 4 or more) spray units 10, it may be a circle, and M connection portions T connecting M sides H and each side H It may have a shape having

  FIG. 8 is a schematic view schematically showing the case 2 viewed from above when the outer peripheral shape of the upper end region of the case 2 is a circle. In FIG. 8, the components corresponding to the components described in the first embodiment are assigned the same reference numerals and descriptions thereof will be omitted. FIG. 8 illustrates the installation table 6 in which three storage chambers 20 related to the three spray units 10 and three storage chambers 16 related to the three liquid supply units 18 are formed. As described above, the position of the storage chamber 20 corresponds to the position of the spray unit 10, and the position of the storage chamber 16 corresponds to the position of the liquid supply unit 18.

  As shown in FIG. 8, even when the outer peripheral shape of the upper end region of the housing 2 is a circle, each of the spray units 10 is separated by the same angle (120 ° in the example of FIG. 8) on one virtual circle KS2. By arranging them, the spray units 10 can be efficiently spaced apart. In addition, by arranging one liquid supply unit 18 in the space between the spray unit 10 and the spray unit 10, the dead space inevitably generated between the spray unit 10 and the spray unit 10 can be effectively used to The supply unit 18 can be arranged efficiently, and the housing 2 can be miniaturized. Although illustration is omitted, in the case where the outer peripheral shape of the upper end region of the housing 2 is a shape having M sides H and M connection portions T connecting the sides H, the same angle (360 By arranging the M spray units 10 in the vicinity of each of the M connection portions T in a state of being separated by an angle / M), each of the M spray units 10 can be efficiently spaced apart on the installation table 6. At this time, by arranging one liquid supply unit 18 in the space between the spray unit 10 and the spray unit 10, the housing 2 can be miniaturized.
