(First embodiment)

Hereinafter, the sprayer of the first embodiment will be described with reference to Figs. 1 to 3 .

As shown in Figures 1 and 2, the housing 11 of the sprayer is in the form of a bottomed cylinder. The upper casing 12 is detachably coupled to the upper casing 13 having a lid-bottomed bottom.

The lower end of the adjuster 15 is fixed in a penetrating state on the bottom portion 14 of the upper casing 13. A sharp tubular needle member 17 is held on a central hole (not shown) of the adjuster 15.

On the outer circumference of the regulator 15, the support cylinder portion 18 projects downward from the bottom portion 14, and a bottomed cylindrical holding casing 19 is formed as a cylinder receiving portion, and the upper end opening is fixed to the support cylinder portion 18 via a screw. The periphery.

The gas cylinder 22 as a gas cylinder is housed in the holding casing 19 in a state of being supported by the bottom of the holding casing 19. Moreover, the front end portion of the aforementioned needle-shaped member 17 is pierced by the upper cover 23 of the cylinder 22. Therefore, the carbonic acid gas in the cylinder 22 reaches the needle member 17. A seal 24 for preventing gas from leaking between the upper cover 23 and the needle member 17 is provided on the upper surface of the lid 23 above the cylinder 22.

Adjacent to the holding casing 19, a container accommodating portion 30 is formed in the lower casing 12. A lotion container 31 as a liquid container is detachably provided in the container accommodating portion 30, and a lotion is accommodated therein. A tube 32 is connected to the upper end of the lotion container 31, and the lotion sucked up there is passed. In addition, in order to prevent the inside of the lotion container 31 from being negatively pressurized by the absorption of the lotion, a small hole (not shown) is formed in the upper end portion of the lotion container 31.

As shown in Figs. 2 and 3, a valve body 41 constituting an on-off valve is connected to the upper portion of the regulator 15. A connecting pipe 42 is protruded from the valve body 41. The connecting pipe 42 communicates with the internal passage of the needle member 17 via a passage (not shown) in the valve body 41 and the regulator 15.

A spray port 51 opening toward the outside is fixed to the side wall of the upper casing 13. A nozzle 52 constituting a spray mechanism is fitted into the base end portion of the spray port 51. At the base end of the nozzle 52 The connecting pipe 42 is connected to the portion. The supply port 43 constituting the spray mechanism is inserted and fixed to the lower peripheral wall of the spray port 51. The tube 32 is connected to the proximal end portion of the spray port 51. The front end opening of the supply port 43 is disposed at the front end opening of the nozzle 52. When the gas is ejected from the nozzle 52 at a high speed, the vicinity of the opening of the front end of the supply port 43 becomes a negative pressure, and the lotion in the lotion container 31 is sucked up. Therefore, the lotion becomes a spray and is ejected from the opening of the spray port 51 together with the jet of the carbon dioxide gas.

An operation button 61 as an operation portion is provided at an upper end of the upper casing 13. By operating the operation button 61 in a depressed manner, a valve (not shown) in the valve body 41 is pressed by a lifting rod (not shown) to open a passage between the needle member 17 and the nozzle 52. Therefore, the carbon dioxide gas in the cylinder 22 connected to the primary side of the valve body 41 is supplied to the nozzle 52 via the passage and the connecting pipe 42.

In the first embodiment, the holding case 19 and the lotion container 31 are provided in close proximity to each other in the lower casing 12. Therefore, the gas cylinder 22 and the lotion container 31 are placed close to and in parallel. Further, the abutting portion of the valve, the valve, the operation button 61 via the elevating rod, and the holding casing 19 are disposed on an axis extending in the vertical direction.

Next, the action of the atomizer of the first embodiment will be described.

In this sprayer, the holding case 19 and the gas cylinder 22, and the container accommodating portion 30 and the lotion container 31 are provided in close proximity and in parallel. Therefore, the entire sprayer has a small outer shape and is formed in a simple cylindrical shape that is long and long. Therefore, the sprayer is naturally easy to carry.

Further, when the sprayer is used, the operation button 61 is pressed with an index finger or the like while holding the casing 11 with one hand, and the valve is opened. At this time, the spray of the lotion is ejected from the spray port 51 with the jet of carbon dioxide gas. Thus, the spray can be brought into contact with the carbon dioxide gas.

Therefore, according to the atomizer of the first embodiment, the following effects can be obtained:

(1) In the case of the atomizer of the first embodiment, the holding case 19 is provided in parallel The lotion container 31. Therefore, the gas cylinder 22 and the lotion container 31 are housed in the sprayer, but the entire sprayer is simple cylindrical and small. Therefore, the sprayer is small in size, easy to carry and easy to hold. Therefore, the sprayer can be easily used for makeup at a destination such as a trip.

(2) A spray mechanism including the spray port 51 is disposed at the upper end portion of the outer casing 11, and the holding casing 19 is disposed under the spray mechanism, and the lotion container 31 is disposed below the spray port 51 and the supply port 43. Therefore, the entire sprayer can be made elongated to be shaped to be carried and held.

(3) Since the operation button 61 for opening and closing the spray mechanism is provided at the upper end of the casing 11, in the state in which the casing 11 is held by one hand, the one-handed index finger or the like can be simply pressed and operated. The button 61 is operated. Therefore, the spray operation of the sprayer can be easily performed with one hand, so that the operation of other cosmetic tools can be performed with the remaining one hand.

(4) The spray port 51 opened to the outside of the casing 11 is fixed to the inner side of the casing 11, and the nozzle 52 and the supply port 43 are fixed to the spray port 51. Therefore, the nozzle 52 and the supply port 43 can be unitized. Therefore, it is possible to contribute to downsizing of the atomizer, and it is easy to replace when, for example, the nozzle 52 is clogged.

(5) The valve, the holding casing 19 of the cylinder 22, and the abutting portion of the valve and the operation button 61 are disposed on one axis. Therefore, the entire sprayer can be elongated to form a small object. Thus, the sprayer is easy to carry or hold.

(Second embodiment)

Next, the nebulizer according to the second embodiment will be described with reference to Figs. 4 to 7 .

In the second embodiment, as in the first embodiment, the housing 11 of the atomizer includes the lower casing 12 and the upper casing 13. In the second embodiment, in order to detachably connect the upper casing 13 to the lower casing 12, the structure shown in Fig. 7 is employed.

A projection 71 extending downward is formed on the bottom portion 14 of the upper casing 13. A pair of hooked portions 72 are formed on the projection 71, respectively, in a direction away from each other. It is opposed to each other via the axis L1 of the upper casing 13 and the lower casing 12. Further, a base 70 is fixed to the bottom portion 16 of the lower casing 12, and a release button 73 having a connection relationship is slidably attached to the base 70 in the vertical direction. The pair of rods 74 extending in the up-and-down direction are slantably movable by the shafts 75, and are supported at positions opposed to each other via the axis L1 inside the lower casing 12. A catching portion 76 that protrudes in a direction approaching each other is formed at an upper end portion of each of the rods 74. The two catching portions 76 move with the tilt of the lever 74, and are caught and disengaged by the caught portion 72. A wrist portion 77 that extends toward the opposing lever 74 is formed at a lower end portion of each of the rods 74. The spring 78 of the coil spring or the like is interposed between the front end portions of the two arm portions 77 in a compressed state. The two levers 74 are energized by the spring 78 so that the respective latching portions 76 engage with the engaged portion 72. The pair of pressing portions 79 are protruded upward from the release button 73 of the above-described connection relationship. These pressing portions 79 are in contact with the front end portions of the two arm portions 77 from below.

In the second embodiment, as in the first embodiment, the lower end portion of the regulator 15 is fixed to the bottom portion 14 of the upper casing 13. However, in the second embodiment, as shown in Fig. 4, the holding casing 19 is not disposed below the regulator 15 inside the casing 11. In the second embodiment, a part of the space in the casing 11 serves as a cylinder accommodating portion 81 for accommodating the gas cylinder 22 instead of the holding casing 19. An external thread 82 is formed on the outer peripheral surface of the upper end portion of the cylinder 22. The cylinder 22 is detachably mounted to the regulator 15 by screwing the additional thread 82 into the internal thread 83 formed at the lower end of the adjuster 15. These cylinders 22 and regulators 15 are disposed on the same axis L2. The valve body 41 constituting the switching valve is disposed at a position deviated from the above-described axis L2, here being the side of the regulator 15.

As shown in FIGS. 4 and 5, the nozzle 52 and the spray port 51 are fixed to the valve body 41, and the regulator 15, the valve body 41, the nozzle 52, and the spray port 51 are unitized.

The cylindrical covering portion 84 that opens the upper and lower ends is inserted into the lower peripheral wall of the spray port 51, and is fixed to the same spray port 51. In the covering portion 84, the portion extending into the inside of the spray port 51 is formed into a tapered shape so that the diameter becomes higher toward the upper side. Moreover, before the supply port 43 The end portion can be inserted into the cover portion 84 from below.

The upper end of the tube 32 is connected to the base end of the supply port 43, and the lower end of the tube 32 is connected to the lotion container 31. This point is the same as that of the first embodiment.

The base end of the supply port 43 and the entire tube 32 are covered by a tube cover 85. The tube cover 85 extends upward from the lid 86 attached to the upper end portion of the lotion container 31. The lotion container 31, the tube 32, the lid 86, the tube cover 85, and the supply port 43 are assembled to each other to constitute the container unit 87.

On the side wall of the lotion container 31, a pair of protrusions 88 are formed so as to face each other with an axis (not shown) of the lotion container 31 interposed therebetween. Further, on the lower end portion of the upper casing 13, the elastic pieces 89 are respectively formed at places (not shown) which are covered by the lower casing 12 and correspond to the above-mentioned two projections 88. The positions of the projections 88 and the elastic pieces 89 are set such that the projections 88 and the elastic pieces 89 are joined to each other in a state where the supply opening 43 is inserted into the covering portion 84.

As shown in Fig. 6, on the bottom portion 16 of the lower casing 12, a double cylindrical mounting portion 91 is opened at the upper end, and is protruded upward from a position below the container accommodating portion 30. A non-solid elastic member 92 made of an elastic material such as rubber is inserted into the mounting portion 91 from above and attached to the mounting portion 91. This elastic member 92 is disposed in a state where it is elastically deformed between the bottom portion 16 of the lower casing 12 and the lotion container 31. The elastic member 92 is elastically deformed to catch the lotion container 31 from the lower side.

A hole 93 that communicates the inside and the outside of the lotion container 31 is formed in a part of the wall portion of the lotion container 31. A waterproof sheet 90 that blocks the waterproof and moisture permeability of the hole 93 is attached to the upper wall portion of the lotion container 31. This filter 94 is formed, for example, of a polyurethane film having a plurality of fine pores smaller than water molecules and larger than water vapor.

The structure other than the above is the same as that of the first embodiment. Therefore, the same elements as those described in the first embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.

Next, the action of the nebulizer of the second embodiment will be described.

In the sprayer, the valve body 41 is disposed to be displaced from the cylinder accommodation portion 81. The cylinder 22 and the axis L2 of the regulator 15 are located. Therefore, the size of the sprayer of this embodiment with respect to the direction of the axis L2 is shortened compared to the sprayer of the other embodiment in which the valve body 41 is disposed on the same axis L2 as the cylinder 22.

Conversely, with the above arrangement of the valve body 41, the size of the atomizer in the direction orthogonal to the above-described axis L2 becomes large. However, since the nebulizer of the second embodiment does not include the holding case 19, the portion holding the thickness of the case 19 can be placed close to the gas bottle 22, and the lotion container 31 can be disposed. Thereby, the increase in the size of the atomizer in the direction orthogonal to the above-described axis L2 with the above arrangement of the valve body 41 can be suppressed. Therefore, the entire sprayer is still miniaturized and naturally portable.

As shown in Fig. 7, in the above-described atomizer, when the release button 73 of the connection relationship is in the non-operating state, the two arm portions 77 are energized by the springs 78 in a direction away from each other (away from). This ability is transmitted to the two latching portions 76 via the two levers 74, and each of the latching portions 76 is engaged with the latched portion 72. Therefore, the upper casing 13 is connected to the lower casing 12, and the upper casing 13 is less likely to fall off from the lower casing 12.

Further, at this time, the elastic deformation member 92 is used to catch the container unit 87 from the lower side. Thereby, unnecessary movement of the container unit 87, such as sloshing, can be restricted.

Further, since the release button 73 of the above-described connection relationship is disposed at the bottom portion 16 of the lower casing 12, the release button 73 of the connection relationship is disposed in another place, and this design is less likely to be accidentally pressed.

Similarly to the first embodiment, the nebulizer is operated by pressing the operation button 61 with an index finger or the like while holding the casing 11 with one hand. By the above-described valve opening and closing, the carbon dioxide gas is supplied to the nozzle 52, and the spray of the lotion is ejected from the spray port 51 with the jet of carbon dioxide gas. Thus, the spray can be brought into contact with the carbon dioxide gas.

When at least one of the container unit 87 and the gas cylinder 22 is replaced or when the front end of the cleaning supply port 43 is opened, for example, the release button of the connection relationship is operated by pressing with a finger. 73, you can achieve. With the release button 73 of this connection relationship, the force pushing the wrist portion 77 acts on each of the wrist portions 77. With this force, the two rods 74 are tilted and moved with the shaft 75 as a fulcrum so that the two arms 77 resist the spring 78 and approach each other. By this tilting movement, the two catching portions 76 are displaced in the direction away from each other, and are separated from the corresponding jammed portion 72. Thereby, the connection state of the upper casing 13 to the lower casing 12 can be released. Therefore, the upper casing 13 can be removed from the lower casing 12.

When the upper casing 13 is removed from the lower casing 12, the container unit 87 and the cylinder 22 assembled to the upper casing 13 can be taken out from the container accommodating portion 30 and the cylinder accommodating portion 81 of the lower casing 12. Further, the container unit 87 can be detached from the upper casing 13 by elastically deforming the elastic pieces 89 of the upper casing 13 and releasing the engagement state of the projections 88 with the elastic piece 89. Further, the cylinder 22 assembled to the regulator 15 so far is rotated around the axis L2 in the direction in which the internal thread 83 and the external thread 82 are loosened, and the cylinder 22 can be detached from the regulator 15.

Next, the new container unit 87 can be inserted into the cover portion 84 into the supply portion 43 from below by the upper casing 13 detached from the lower casing 12 as described above. In the middle of the insertion, the projection 88 abuts against the elastic piece 89 to elastically deform the same elastic piece 89 to the outside. The supply port 43 enters the covering portion 84, and the projection 88 opposes the elastic piece 89, and each of the projections 88 is joined to the corresponding elastic piece 89 by the elastic restoring force of the elastic piece 89. Further, the cylinder 21 is attached to the regulator 15 by rotating the new cylinder 22 in the direction in which the internal thread 83 and the external thread 82 are tightened around the axis L2.

In this way, the new container unit 87 and the gas cylinder 22 are attached to the upper casing 13.

The interval between the two catching portions 76 is enlarged by the release of the release button 73 of the connection relationship by pressing. In this state, the container unit 87 is placed in the container accommodating portion 30 of the lower casing 12, and the gas cylinder 22 is placed in the cylinder accommodating portion 81 of the lower casing 12.

At this time, the elastic member 92 is pressed by the lotion container 31 of the container unit 87 to be elastically deformed between the bottom portion 16 of the lower casing 12 and the lotion container 31. The container unit 87 is caught by the elastic member 92 from the lower side.

Then, when the upper casing 13 is placed on the lower casing 12, the finger is released from the release button 73 of the connection relationship. At this time, by the elastic restoring force of the spring 78, the two levers 74 are tilted in the direction in which the distance between the two arm portions 77 is widened with the shaft 75 as a fulcrum, and the two catching portions 76 are joined to the corresponding engaged portion 72. The upper casing 13 is coupled to the lower casing 12 by these joints. Further, the two levers 74 are tilted in the direction in which the distance between the two arms 77 is widened, and the release button 73 of the connection relationship is pressed down to return to the original position before the pressing operation.

As described above, when the lotion container 31 is replaced, it is replaced together with the container unit 87. Therefore, when the lotion container 31 is replaced with the lotion container 31 containing different types of lotion, it is difficult for the lotion before replacement to remain inside the tube 32 or inside the supply port 43.

When the container unit 87 is detached from the upper casing 13, since the front end opening of the supply port 43 is exposed, the cleaning port can be cleaned by the front end opening using the cleaning device.

Further, in the carrying process of the sprayer, the internal pressure of the lotion container 31 may rise due to an increase in temperature or the like. With the posture of the sprayer, for example, when the sprayer is disposed laterally, the lotion in the lotion container 31 may be pushed out through the tube 32 due to the internal pressure of the lotion container 31 thus rising, and leaked from the supply port 43.

In the second embodiment, the water-permeable and moisture-permeable filter sheet 94 is used to block the hole 93 formed in a part of the wall portion of the lotion container 31. Therefore, even if the temperature inside the lotion container 31 becomes higher as the temperature rises, the air in the lotion container 31 is released to the outside of the lotion container 31 through the filter sheet 94, and inside the lotion container 31. The phenomenon of high pressure is hard to occur. Thereby, it is possible to suppress leakage of the lotion through the tube 32 and the supply port 43 due to an increase in the internal pressure of the lotion container 31.

Therefore, according to the second embodiment, in addition to the same effects as the above effects (1) to (3), the following effects can be obtained:

(6) The cylinder accommodating portion 81, the cylinder 22, and the regulator 15 are disposed on the same axis L2, and the valve body 41 is disposed at a position offset from the axis L2. Therefore, the size of the atomizer in the direction of the axis L2 can be made shorter than that of the first embodiment, and the size of the entire atomizer can be reduced.

(7) A part of the casing 11 (the space below the regulator 15) functions as a cylinder accommodating portion 81 instead of the holding casing 19. The upper end portion of the gas cylinder 22 is supported by being directly attached to the regulator 15 by a screw. Since the sprayer does not have the holding case 19, the sprayer can be constructed with a small number of parts. Further, the portion of the thickness of the outer casing 19 can be disposed so that the lotion container 31 approaches the gas cylinder 22. With the above configuration of the valve body 41, the size of the atomizer in the direction orthogonal to the axis L2 is increased, and it can be suppressed.

(8) The lotion container 31, the tube 32, the lid 86, the tube cover 85, and the supply port 43 are assembled to each other to constitute the container unit 87. Therefore, when the lotion container 31 is replaced with the lotion container 31 containing different kinds of lotions, it can be replaced together with the container unit 87. Thereby, it is possible to prevent the old and new lotions from being mixed inside the tube 32 or inside the supply port 43.

Further, the supply port 43 can be withdrawn from the spray port 51 by detaching the container unit 87 from the upper casing 13. Therefore, even if the supply port 43 is clogged, the supply port 43 can be extracted and the clogging can be cleared. Further, the above-described cleaning is not performed, and the new container unit 87 is assembled to the upper casing 13, whereby the blocked supply port 43 can be replaced with the unplugged supply port 43.

(9) The regulator 15, the valve body 41, the spray port 51, and the nozzle 52 are assembled to the casing 11 in a unitized state.

Therefore, the above plurality of members can be used as one assembly, and the processing can be easily performed.

(10) on the bottom 16 of the lower casing 12 below the container receiving portion 30 The elastic member 92 is disposed at a place. Therefore, by holding the lotion container 31 from the lower side by the elastic member 92, unnecessary movement of the lotion container 31 can be suppressed. Further, the elastic deformation of the elastic member 92 can absorb the dimensional error in the direction of the axis L1 of the casing 11, the cylinder 22, and the axis L2 of the adjuster 15, so that the dimensional management of the article is easy.

Further, the non-solid elastic member 92 is inserted into the double cylindrical mounting portion 91. Therefore, the space of the elastic member 92 in the mounting portion 91 can be elastically deformed, and the state in which the elastic member 92 is kept contracted by the elastic deformation can be suppressed.

(11) A hole 93 is formed in a part of the wall portion of the lotion container 31, and the hole 93 is blocked by the waterproof and moisture-permeable filter sheet 94. Therefore, the air in the lotion container 31 can be released to the outside of the lotion container 31 through the filter sheet 94 and the hole 93. Therefore, even if the temperature inside the lotion container 31 becomes higher as the temperature rises or the like, the increase in the internal pressure of the lotion container 31 can be suppressed, and the makeup water can be prevented from leaking from the tube 32, the supply port 43, and the like.

(change example)

Each of the above embodiments may be modified as follows:

. It is also possible to provide a cover on the outer side of the upper casing 13 that is movable between a position covering the opening of the spray port 51 and a position from which it is withdrawn.

As an example of such a cover, the double-dotted line in Fig. 2 shows the cover 101. A communication hole 102 that opens and closes the opening of the spray port 51 is formed on the cover 101 as it moves up and down. The lid 101 is moved up and down to a position where the communication hole 102 faces the opening, and the opening is opened. When the lid 101 is moved up and down to a position where the communication hole 102 moves upward or downward from the opening, the lid 101 is used to close the opening.

Therefore, when the sprayer is not in use, the opening of the spray port 51 is blocked by the lid 101, and foreign matter such as dust can be controlled to enter the spray port 51. Further, when the sprayer is used, the opening of the spray port 51 is opened, and the spray of the lotion can be ejected.

The cover 101 may also be formed such that its surface does not protrude outward from the surface of the lower casing 12. Out. That is, it is preferable that the surface of the cover 101 and the surface of the lower casing 12 are disposed on the same plane. In this case, no step is generated between the cover 101 and the casing 11.

Further, the communication hole 102 may be changed to a notch.

. A cleaning mechanism for cleaning the inside of the supply port 43 may be provided above the supply port 43.

The two-dot chain line in Fig. 5 shows an example of the cleaning mechanism. The cleaning mechanism includes a brush 103 disposed above the supply port 43. The brush 103 includes a shank 104 extending in the vertical direction and penetrating the upper peripheral wall of the spray port 51, and a plurality of bristles 105 implanted in the lower end portion of the shank 104 in a bundled state. The brush 103 is preferably configured to move up and down in conjunction with the vertical movement of the upper casing 13. Here, the interlocking design of the brush 103 is such that the hair 105 enters the supply port 43 when the upper casing 13 is moved downward to cover the lower casing 12. When the upper casing 13 is moved upward, the hairs 105 are withdrawn from the supply port 43.

In this manner, by moving the upper casing 13 downward toward the lower casing 12, the hair 105 is inserted into the inside of the supply port 43, and the makeup water stuck inside the supply port 43 can be removed. In this case, the container unit 87 may not be detached from the upper casing 13 in order to release the clogging.

. It is also possible to provide a mechanism between the operation button 61 and the upper casing 13, which is incapable of locking the operation button 61 or releasing the lock as the upper casing 13 moves up and down.

For example, in a state where the upper casing 13 is moved downward and is placed on the lower casing 12, the operation button 61 is inoperably locked. Further, when the upper casing 13 is moved upward, the above-described locking is released and the operation button 61 is operated. This mechanism can be realized by a combination of, for example, a cam mechanism, a link mechanism, and the like.

In this case, for example, when the nebulizer is placed in a bag or the like and carried, even if the hand is placed in the purse to find something and the operation button 61 is touched, the pressing operation to the operation button 61 can be prevented from injecting the carbon dioxide gas.

. The nebulizer may be applied to a nebulizer that contains a liquid of a different type from the lotion in a liquid container, or a nebulizer that injects a gas different from carbon dioxide into the cylinder 22 in a compressed state.

. It is also possible to add other members to the lower casing 12 and the upper casing 13 on the casing 11.

. The supply port 43 and the tube 32 may be assembled to the spray port 51 to be unitized, and the tube 32 of this unit may be detachably attached to the lotion container 31.

. In order to detachably connect the upper casing 13 to the lower casing 12, a structure different from that of the second embodiment may be employed.

An example of this configuration is shown in Figs. 8 to 11. As shown in Fig. 8, the upper casing 13 has an attached portion 111 formed in a substantially cylindrical shape at a lower portion thereof. When the upper casing 13 is coupled to the lower casing 12 of Fig. 9, the upper portion of the lower casing 12 is placed on the attached portion 111. As shown in Fig. 11, on the attached portion 111, a pair of rods 112 (only one of which is shown in Fig. 11) are tiltably movable by the shaft 113, and are supported by the axis of the upper casing 13 (illustration Omitted) and opposite places. At the lower end portion of each of the rods 112, a claw portion 114 that is outwardly led out from the above-mentioned attached portion 111 as it moves obliquely is formed. Each of the rods 112 is energized to the claw portion 114 by a spring 115 such as a coil spring from a direction in which the attached portion 111 protrudes.

As shown in Fig. 9, a pair of joint portions 116 formed of recesses or holes are formed in the upper portion of the lower casing 12, and are integrated with the claw portions 114 when the cover is placed on the attached portion 111. The two claw portions 114 project outward from the attached portion 111 and enter the corresponding joint portion 116, thereby connecting the upper casing 13 to the lower casing 12. Further, when the two claw portions 114 are immersed in the attached portion 111 and are separated from the corresponding joint portion 116, the connection state of the upper casing 13 to the lower casing 12 can be released.

As shown in FIGS. 8 and 10, the release button 117 of the connection relationship is disposed in the radial direction of the casing 11 so as to be disposed on the side of the upper casing 13 and below the spray port 51. in Between the release button 117 of the connection relationship and the two levers 112, a transport mechanism 118 that transmits the movement of the release button 117 of the connection relationship to the two levers 112 to tilt the lever 112 is disposed. The transport mechanism 118 includes a slide member 119 that slides in the radial direction of the casing 11 in conjunction with the release button 117 of the connection relationship, a pair of arm portions 121 that are respectively formed on the upper portions of the rods 112, and a slide member 119 that is vertically movable. A lifting member 122 between the rod 112 and the rod 112. A slope 119a that is in contact with the lifting member 122 is formed on the sliding member 119.

With the above configuration, as shown by the arrow A1 in FIGS. 10 and 11, the release button 117 of the connection relationship is pressed, as shown by the arrow A2, the sliding member 119 approaches the axis of the casing 11 as shown by the arrow A2. slide. With this sliding, as shown by the arrow A3, the elevating member 122 rises along the slope 119a of the sliding member 119. At this time, the lifting and lowering member 122 acts on the rod 112 via the arm portion 121, and the same rod 112 resists the spring 115 and moves obliquely with the shaft 113 as a fulcrum. With this tilting movement, the claw portions 114 of the respective rods 112 are immersed in the attached portion 111 and are separated from the joint portion 116. Therefore, the upper outer casing 13 can be separated from the lower outer casing 12.

Further, in a state where the lower casing 12 is attached to the attached portion 111, when the release button 117 for pressing the connection relationship is stopped, the elastic restoring force of each spring 115 is utilized, and each of the rods 112 is moved from the attached portion 111 by the claw portion 114. The outer protruding manner is tilted, and the claw portions 114 of the respective rods 112 enter the joint portion 116 to be engaged. The upper casing 13 is coupled to the lower casing 12 by these joints. At this time, the tilting movement of each of the rods 112 is transmitted to the elevating member 122 through the arm portion 121, and is lowered together with the elevating member 122. By the descending elevating member 122, the sliding member 119 slides away from the axis of the casing 11, and in conjunction with this, the release button 117 of the connection relationship is pushed back to the position before the pressing.
