A stem disposed in a possible manner, and a top-bottomed cylindrical pressing head mounted on the stem, the top wall portion of the pressing head being disposed away from the stem, The top wall portion is provided with the impregnated body and a storage concave portion in which the volatilizing agent that has collided with the top wall portion of the pressing head and dropped after being discharged from the upper end opening of the stem is formed. ing.

According to this volatilization apparatus, the pressing head of the discharger is pressed down to lower the stem, and the discharger is operated to discharge the volatilizing agent in the container body from the upper end opening of the stem. After making it collide with a wall part, it can be dropped and can be stored in the storage recessed part of the upper surface of a mounting cap. Therefore, the impregnated body is erected in the storage recess and the volatilizing agent in the storage recess penetrates into the impregnated body, so that the volatilizing agent can be evenly distributed over the impregnated body. Therefore, the volatilizing agent impregnated in the impregnated body by the air blown onto the impregnated body can be vaporized by evaporating evenly and efficiently.
In addition, since the volatilizer discharged from the discharge container is volatilized, not the volatilizer contained in the discharge container, even if this volatilization device is left, a larger amount of volatilization than the amount discharged from the discharge container It is possible to suppress the agent from being volatilized wastefully.

The discharger includes a cylinder in which the stem is inserted so as to be movable up and down, and a piston that is slidable in the vertical direction and is linked to the stem.

Hereinafter, a volatilization apparatus according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a partial longitudinal sectional view showing an embodiment of a volatilization apparatus according to the present invention, and reference numeral 10 in FIG. 1 is a volatilization apparatus. The volatilization apparatus 10 volatilizes liquid volatilizers having volatility such as fragrances, deodorants, insecticides, repellents, and disinfectants.

  The volatilization device 10 is detachably attached to an air outlet (not shown) provided in a vehicle (not shown), for example. The blower opening is provided with fins (not shown) for adjusting the direction of the flow of air blown from the blower opening. A plurality of fins are arranged at intervals in the vertical direction Z. The blower outlet blows out air between fins adjacent in the vertical direction Z. The air outlet blows air from the front to the rear along the front-rear direction X orthogonal to the vertical direction Z. The fin extends in the left-right direction Y orthogonal to both the vertical direction Z and the front-rear direction X.

The volatilization apparatus 10 includes a support member 11, an attachment member 12, a discharge container 13, an impregnation body 14, and a cover member 15.
The support member 11 is disposed in front of the blower opening, and includes a back wall portion 21, a bottom wall portion 22, and a pair of first side wall portions 23. The rear wall portion 21 is arranged so as to cover the air blowing port from the rear, and extends in the vertical direction Z and faces the front-rear direction X.

  The rear wall portion 21 is provided with a through hole 24 and a vent hole 25. The through hole 24 penetrates the back wall portion 21 in the front-rear direction X, is formed and arranged at the center portion in the left-right direction Y of the back wall portion 21, and is arranged at substantially the center portion in the vertical direction Z. The vent hole 25 is formed through the back wall portion 21 and has a long hole shape extending in the left-right direction Y. Has been placed. Further, although not shown, a plurality of vent holes 25 may be arranged extending in the vertical direction on the left and right sides of the through hole 24.

  The bottom wall portion 22 protrudes from the lower end portion of the back wall portion 21 toward the rear (discharge container 13 side) and faces the vertical direction Z. Although not shown, the bottom wall portion 22 is formed with a fitting hole and a passage hole that penetrate the bottom wall portion 22 in the vertical direction Z so as to communicate with each other. The fitting hole is formed in a circular shape in plan view when the volatilization device 10 is viewed from the vertical direction Z. The passage hole is formed to open from the fitting hole toward the outside in the radial direction, that is, the side opposite to the back wall 21.

  The pair of first side wall portions 23 is erected on both ends in the left-right direction Y of the bottom wall portion 22, extends in the vertical direction Z, and faces the left-right direction Y. The front end portion of the first side wall portion 23 is connected to the end portion in the left-right direction Y of the back wall portion 21.

  The attachment member 12 has a pair of upper and lower clamping pieces 27 projecting forward and a mounting pin 28 projecting rearward. The mounting pin 28 can be attached to and detached from the through hole 24 of the back wall portion 21. By being fitted to the support member 11, the support member 11 is attached. Further, the attachment member 12 is attached to the blower opening by a pair of holding pieces 27 holding the fin in the vertical direction Z and engaging with the fin. Thereby, the support member 11 is attached to the fin of the blower opening via the attachment member 12.

  The discharge container 13 is located behind the back wall portion 21 and is disposed on the opposite side of the air blowing port with the back wall portion 21 interposed therebetween. The discharge container 13 is attached to the support member 11 with its axis O along the vertical direction Z. It is supported. The discharge container 13 includes a container body 30 in which a volatile agent is accommodated, and a discharger 31 attached to the container body 30.

  The container body 30 is formed in a bottomed cylindrical shape, and the central axis of the container body 30 is the axis O (central axis) of the discharge container 13. The container body 30 is formed in the order of a bottom portion 30a, a trunk portion 30b, a shoulder portion 30c, and a mouth portion 30d from below to above.

  The discharger 31 is mounted on the container body 30 and discharges the volatile agent in the container body 30 and has a so-called pump type configuration. The discharger 31 includes a mounting cap 40 that is mounted on the mouth portion 30 d of the container body 30, a cylinder 41, a stem 42, a pressing head 43, and a piston 50.

The mounting cap 40 is formed in a cylindrical shape as shown in FIG.
The peripheral wall part is formed in a double cylinder shape having an outer cylinder part 40b and an inner cylinder part 40c surrounded by the outer cylinder part 40b, and is screwed to the mouth part 30d of the container body 30 to the inner cylinder part 40c. An internal thread portion is formed. The lower end edge of the outer cylinder part 40 b is supported by the bottom wall part 22.

  The top wall portion 40a is formed in an annular shape arranged coaxially with the axis O, and has an insertion cylinder 40e protruding downward on the inner peripheral edge thereof. A storage recess 44 for storing the volatilizing agent K discharged from the stem 42 is formed at the outer peripheral edge of the top wall 40a. The storage recess 44 is formed in an annular shape arranged coaxially with the axis O in plan view. An upper cylinder 40 d that protrudes upward is formed in a portion of the top wall 40 a that is located between the insertion cylinder 40 e and the storage recess 44.

  In the illustrated example, the upper cylinder 40d is disposed at the opening peripheral edge of the storage recess 44 in the top wall 40a. A slit hole 45 that opens upward is formed in the upper cylinder 40d. The lower end of the slit hole 45 is located above the upper surface of the top wall part 40a, and is located below the upper end of the outer cylinder part 40b. As a result, the slit hole 45 allows the inside of the storage recess 44 to communicate with the inside of the upper cylinder 40d so that the volatilizing agent K stored in the storage recess 44 does not overflow over the outer cylinder 40b as will be described later. The volatilizer K is collected inside the upper cylinder 40d.

  Thus, the volatilizing agent K that has overflowed from the storage recess 44 through the slit hole 45 can be temporarily stored between the insertion tube 40e and the upper tube 40d. The gap between the insertion tube 40e and the stem 42 serves as a collection passage 39 that can communicate with an air hole 48 described later.

  In the storage recess 44, the impregnated body 14 is erected along the circumferential direction. The impregnated body 14 is a cylindrical member formed of a porous material such as a filter paper or a sponge body, and is disposed coaxially with the axis O. The impregnated body 14 has a lower end portion disposed in the storage recess 44, and therefore, the volatilizing agent K penetrates efficiently and evenly by directly contacting the volatilizing agent K stored in the storage recess 44. It is like that. Further, the upper end side of the impregnated body 14 is formed so as to extend to the vicinity of the upper end of the uppermost vent 25 of the rear wall portion 21 of the support member 11. Further, the impregnated body 14 is arranged so that the outer peripheral surface thereof is close to the inner peripheral surface of the outer cylindrical portion 40 b of the mounting cap 40. That is, an annular minute gap is formed between the outer peripheral surface of the impregnated body 14 and the inner peripheral surface of the outer cylinder portion 40b, and thereby the impregnated body 14 is attached to the volatilizing agent K stored in the minute gap. Also comes in contact.

  The upper end portion of the cylinder 41 is fitted between the outer peripheral surface of the insertion tube 40e and the inner peripheral surface of the upper tube 40d. Accordingly, the cylinder 41 is disposed so that the inside thereof communicates with the insertion tube 40e. Further, the cylinder 41 can be communicated with the inside of the container body 30 as shown in FIG. 1, and is formed in a multistage cylindrical shape that gradually decreases in a step shape from the upper side to the lower side. The cylinder 41 is provided with an urging member 46 made of a spring and a valve body 47 made of a ball valve. In addition, as shown in FIG. 2, the cylinder 41 is formed with an air hole 48 penetrating between the inside and the outside below the lower end of the insertion tube 40e. The air hole 48 allows communication between the upper side in the cylinder 41 and the inside of the container body 30.

  A bottomed cylindrical stem 42 is movably inserted into the insertion tube 40e. The stem 42 is inserted into the insertion cylinder 40e and is movably inserted into the cylinder 41 below the insertion cylinder 40e. The stem 42 is urged upward by an urging member 46 provided in the cylinder 41, and is thereby disposed on the mounting cap 40 so as to be movable downward in an upward urged state.

In addition, the stem 42 has a communication hole 49 formed in the peripheral wall portion on the lower end side thereof for communication between the inside and the outside, whereby the volatilizing agent K that has flowed into the cylinder 41 passes through the communication hole 49 and the stem 42. Inflow into 42 is possible.
A piston 50 is disposed between the stem 42 and the cylinder 41. The piston 50 moves up and down in cooperation with the stem 42 and covers the communication hole 49 of the stem 42 so that it can be opened and closed, and covers the air hole 48 of the cylinder 41 so that it can be opened and closed.

  A pressing head 43 is attached to the upper end portion of the stem 42. The pressing head 43 has a substantially cylindrical shape disposed coaxially with the axis O, and protrudes downward from a cylindrical body having a head shape 43a and a top wall portion 43c of the head body 43a. This is a one-part member having a fitting cylinder 43e fitted on the upper end of the stem 42 and a dispersion protrusion 43d provided on the inner side of the fitting cylinder 43e on the top wall 43c of the head body 43a.

The fitting cylinder 43e is formed such that the inner diameter of the upper end portion is smaller than the lower end side, and therefore, the lower side of the small diameter portion is fitted to the upper end portion of the stem 42. A plurality of (for example, four) slits 43f extending over the entire length in the vertical direction Z are formed in the fitting cylinder 43e at predetermined intervals in the circumferential direction. Further, a non-formed portion of the slit 43f, that is, between the slits 43f and 43f, is a plate shape extending in the vertical direction Z and continuing to the top wall portion 43c, and extending in the radial direction and continuing to the inner peripheral surface of the head body 43a. The locking piece 43b is formed.
The inner side in the radial direction of the locking piece 43b is formed longer than the fitting cylinder 43e, and thus extends downward from the lower end of the fitting cylinder 43e. The radially outer side of the locking piece 43b is formed to be shorter than the radially inner side because the lower end side is cut away. Thus, the radially outer lower end of the locking piece 43b is sufficiently separated upward in the vertical direction Z with respect to the upper end of the upper cylinder 40d. Therefore, when the pressing head 43 is pressed, the upper cylinder 40d of the mounting cap 40 can relatively enter the lower end side on the radially outer side of the locking piece 43b.

The top wall portion 43c is arranged away from the upper end of the stem 42, that is, away from the top. As a result, the volatilizing agent K discharged from the stem 42 can expand in the radial direction until it collides with the top wall 43c.
The dispersion protrusion 43d is disposed in the upper end opening 42a of the stem 42 with a gap around the dispersion protrusion 43d without blocking the upper end opening 42a, and the volatilizing agent K discharged from the upper end opening 42a. Is substantially cylindrical. That is, the volatilizing agent K discharged from the upper end opening 42a is guided radially outward by colliding with the outer peripheral surface of the dispersion protrusion 43d that gradually decreases in diameter toward the lower side, and then collides with the inner surface of the top wall portion 43c. After that, it bounces off, passes through the slit 43f, and falls to the inner peripheral surface side of the cylindrical portion of the head main body 43a. Thereby, the volatilizing agent K falls in the storage recessed part 44 along the cylindrical inner peripheral surface of the head main body 43a.

  The mouth portion 30 d of the discharge container 13 is disposed in the fitting hole by passing through a passage hole communicating with the fitting hole of the bottom wall portion 22. That is, the bottom wall portion 22 is elastically deformed to widen the passage hole, and the discharge container 13 is passed from the rear side to the front side (the rear wall portion 21 side), thereby arranging the mouth portion 30d in the fitting hole. Further, the discharge container 13 can be removed from the bottom wall portion 22 by passing the discharge container 13 from the fitting hole toward the rear side through the passage hole.

  The cover member 15 is disposed so as to extend rearward (from the discharge container 13 side) from the back wall portion 21, and includes a top wall portion 52, a front wall portion 53, and a pair of second side wall portions 54. , And is configured. The top wall portion 52 is disposed above the discharge container 12, extends rearward from the upper end portion of the back wall portion 21, and faces the vertical direction Z. Further, the top wall portion 52 has a rear end portion located behind the pressing head 43 and is formed wider in the left-right direction Y than the back wall portion 21. The top wall portion 52 is provided with a pressing convex portion 55 that protrudes downward. The lower end portion of the pressing convex portion 55 has a curved shape that protrudes downward, and is disposed immediately above the pressing head 43.

  The front wall portion 53 extends rearward and obliquely downward from the rear end portion of the top surface wall portion 52 and faces both the vertical direction Z and the front-rear direction X, and the top wall portion 52 has a curved portion 56 interposed therebetween. It is connected. The curved portion 56 is formed in a curved shape that is convex upward. A lower end portion of the front wall portion 53 is disposed at a position equivalent to the bottom wall portion 22 in the vertical direction Z. The front wall portion 53 is formed so that the width in the left-right direction Y is substantially the same as the width in the left-right direction Y of the top wall portion 52. The front wall portion 53 is provided with a projecting piece portion 57. The projecting piece portion 57 projects from the rear end portion of the front wall portion 53 obliquely rearward and upward.

  The pair of second side wall portions 54 includes a front wall portion 54a and a rear wall portion 54b. The front wall portion 54a is projected downward from both ends in the left-right direction Y of the front wall portion 53, and the rear wall portion 54b is directed forward from both ends in the left-right direction Y of the front wall portion 53. Projected. The front wall portion 54a and the rear wall portion 54b are both oriented in the left-right direction Y, and the rear end portion of the front wall portion 54a and the upper end portion of the rear wall portion 54b are continuous. The supporting member 11 is disposed between the pair of second side wall portions 54 and 54. The lower end portion of the front wall portion 54a of each second side wall portion 54 covers the upper end portion of the first side wall portion 23 from the outside in the left-right direction Y.

  The cover member 15 is connected to the support member 11 so as to be rotatable about a rotation axis L extending in the left-right direction Y. In other words, the upper end portion of the back wall portion 21 and the front end portion of the top wall portion 52 are connected via a hinge portion 60 extending in the left-right direction Y, and the hinge shaft of the hinge portion 60 is rotated. It is an axis L.

  In order to volatilize the volatilizing agent K by the volatilization apparatus 10 having such a configuration, first, the attachment member 12 is attached to the air blowing port, and the support member 11 is disposed in front of the air blowing port. Next, in order to discharge the volatilizing agent K from the discharge container 13, the front wall portion 53 of the cover member 15 is pushed forward obliquely downward. Then, as shown in FIG. 3, the cover member 15 rotates downward about the rotation axis L while the pressing projection 55 slides on the pressing head 43, and is directed downward to the pressing head 43. A pressing force is applied.

  As a result, the stem 42 is lowered via the pressing head 43. Then, the volatilizing agent K that first flows into the cylinder 41 from the container body 30 and then flows into the stem 42 through the slit hole 45 of the stem 42 is discharged from the upper end opening 42 a of the stem 42. Then, the discharged volatilizing agent K is guided radially outward by colliding with the outer peripheral surface of the dispersion protrusion 43d, and then collides with the inner surface of the top wall portion 43c, and then bounces back and passes through the slit 43f. 43 a falls to the inner peripheral surface side of the cylindrical portion and is stored in the storage recess 44. A part of the dropped volatilizer K is also stored between the stem 42 and the upper cylinder 40d.

  When the volatile agent K is stored in the storage recess 44 in this manner, the liquid volatile agent K directly contacts the impregnation body 14 because the impregnation body 14 is disposed upright in the storage recess 44. Thus, the volatilizing agent K easily penetrates into the surface layer portion and the inside of the impregnated body 14. At that time, the impregnated body 14 is arranged coaxially with respect to the annular storage recess 44 in plan view, and its lower end is immersed in the liquid volatilizer K, so that the entire immersed part is evenly immersed evenly. At the same time, it penetrates evenly into the upper end side of the impregnated body 14 by capillary action.

  When the volatilizing agent K soaks into the impregnated body 14 in this way and the entire impregnated body 14 is impregnated with the volatilizing agent almost evenly, air from the air blowing port is blown onto the impregnated body 14 through the vent hole 25. Thus, the volatilizing agent K impregnated in the impregnated body 14 is evaporated, and the evaporated volatilizing agent K is volatilized along with the flow of air. That is, the air introduced into the inner space 58 from the blower port through the vent hole 25 is blown to the impregnated body 14, then passes through the inner space 58 and is led out of the volatilization device 10 from the lead-out paths 59 a and 59 b. Is done.

Here, when the amount of the volatilizing agent K that has fallen and stored in the storage recess 44 is large, a part of the volatilizing agent K overflows from the slit hole 45 of the upper cylinder 40d before overflowing over the outer cylinder 40b. Thus, it is stored between the upper cylinder 40d and the stem 42.
Further, when the stem 42 is lowered via the pressing head 43, the piston 50 is pushed down by the lowering of the stem 42, and the air hole 48 of the cylinder 41 is opened.

  Next, in order to stop the discharge of the volatilizing agent K from the discharge container 13, the cover member 15 is rotated obliquely upward and rearward about the rotation axis L, and the pressing force applied to the stem 42 by the pressing head 43 is applied. To release. Then, the stem 42 is restored and moved upward by the urging force of the urging member 46, and the volatilizing agent K in the container body 30 flows into the cylinder 41 due to the negative pressure in the cylinder 41. Further, as the volatile agent K in the container body 30 flows into the cylinder 41, outside air is introduced into the container body 30 through the open air holes 48.

  At that time, the volatile agent K stored between the upper cylinder 40 d and the stem 42 due to overflowing from the storage recess 44 or the like is brought into the container body 30 by the outside air introduced into the container body 30. Inflow. That is, the outside air reaches the air hole 48 through the recovery passage 39 formed by the gap between the insertion tube 40e and the stem 42, and further flows into the container body 30 through the open air hole 48. Accompanying such outside air, the volatilizing agent K is also collected in the container body 30 through the collection passage 39 and the air hole 48.

As described above, according to the volatilization apparatus 10 according to the present embodiment, the pressing head 43 is pressed to lower the stem 42, the discharger 31 is operated, and the volatilizing agent K in the container body 30 is removed from the stem 42. By causing the volatilizing agent K to collide with the top wall portion 43 c of the pressing head 43 by discharging from the upper end opening 42 a, it can be dropped and stored in the storage recess 44. Therefore,
By allowing the impregnated body 14 to stand in the storage concave portion 44 and causing the volatilizing agent K in the storage concave portion 44 to be directly immersed in the impregnated body, the volatilizing agent K can be evenly distributed evenly over the impregnated body 14. Therefore, the volatilizing agent impregnated in the impregnated body by the air blown onto the impregnated body 14 can be vaporized evenly and efficiently.
Moreover, since the volatilizing agent K discharged from the discharge container 13 is volatilized instead of the volatilizing agent K accommodated in the discharge container 13, even if this volatilization apparatus 10 is left, the amount discharged from the discharge container 13 Moreover, it can suppress that a lot of volatilization agents K volatilize.
Therefore, in this volatilization apparatus 10, the volatilizing agent K can be volatilized efficiently.

  Further, the cylinder 42 is provided with a cylinder 41 through which the stem 42 is inserted so as to be movable up and down, and a piston 50 that cooperates with the stem 42. An air hole 48 that is opened and closed by the piston 50 is formed in the cylinder 41, and the stem 42 and the stem are inserted. Since the recovery passageway 39 that can communicate with the air hole 48 is formed between the insertion cylinder 40e and the insertion cylinder 40e, the upper cylinder 40d overflows from the storage recess 44 when the stem 42 is released and is restored upward. The volatilizing agent K that is stored between the stem 42 and reaches the opening peripheral edge of the insertion tube 40e can be collected into the container body 30 through the collection passage 39 and the air hole 48 together with the outside air. Therefore, by collecting the volatilizing agent K not impregnated in the impregnated body 14 in the container body 30, it is possible to efficiently perform volatilization while suppressing unnecessary volatilization of the volatilizing agent K.

  In addition, the support member 11 is provided on the front side of the blower port and has a back wall part 21 through which the vent hole 25 is provided, and the discharge container 13 is placed on the opposite side of the blower hole with the back wall part 21 interposed therebetween. Since it arrange | positions and is supported by the support member 11, when volatilizing the volatile agent K, while arrange | positioning the support member 11 in front of a ventilation port, the volatile agent K is discharged from the discharge container 13 and the impregnation body 14 is impregnated. Let Then, the air from the air blowing port is blown to the impregnated body 14 through the vent 25, whereby the volatilizing agent K impregnated in the impregnating body 14 is evaporated, and the evaporated volatilizing agent K is accompanied by the flow of air. Volatilize. Therefore, the volatilization effect can be further improved.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the pressing head is formed by one part member, but the pressing head may be formed by two part members as shown in FIG.

  The volatilization device 70 shown in FIG. 4 is in the configuration of the volatilization device 10 and the pressing head shown in FIG. That is, the pressing head 71 of the volatilization device 70 shown in FIG. 4 is a two-part member composed of the head main body 72 and the locking cylinder 73. The head main body 72 has a cylindrical shape with a top made of a cylindrical portion 72a and a top wall portion 72b. In this example, the cylindrical portion 72a is formed to have a smaller diameter than the upper cylinder 40d of the mounting cap 40, and thus is disposed in the upper cylinder 40d. An engaging recess 72c is formed in the upper part of the inner peripheral surface of the cylindrical portion 72a. The top wall portion 72b is formed with a dispersion protrusion 72d at the center of the lower surface thereof, and a plurality of locking pieces 72e are formed around the dispersion protrusion 72d.

  The dispersion protrusion 72d functions in the same manner as the dispersion protrusion 43d of the pressing head 43 of the volatilization device 10 shown in FIG. 1. In this example, the dispersion protrusion 72d is not inserted into the upper end opening 42a of the stem 42, but on the upper end opening 42a. Is arranged. However, the dispersion protrusion 72d may also be inserted into the upper end opening 42a in the same manner as the dispersion protrusion 43d as long as the upper end opening 42a of the stem 42 is not blocked.

  The locking pieces 72e are arranged at predetermined intervals in the circumferential direction around the axis O on the inner peripheral surface of the head main body 72, like the locking pieces 43b of the pressing head 43 of the volatilization device 10 shown in FIG. The plate-shaped member extends to the inner surface of the top wall portion 72b and is continuously formed integrally with the top wall portion 72b. These locking pieces 72e function as spacers that provide a predetermined distance between the upper end of the locking cylinder 73 and the lower surface of the top wall portion 72b, and the diameter of the volatile agent K discharged from the upper end opening 42a of the stem 42 is reduced. It also functions as a guide to guide the direction outward.

  The locking cylinder 73 is externally fitted to the upper end of the stem 42 and locked thereto. A cylindrical cylinder main body 73a, and an engaging convex part 73b formed on the outer peripheral surface of the cylinder main body 73a. It is made up of. Of the tube main body 73a, the upper end opening 73c has a smaller diameter than the other part, and the upper end opening 73c is fixed to the upper end of the stem 42 by being locked to the upper end of the stem 42.

  As shown in FIG. 5, which is a plan view of the locking cylinder 73 locked to the stem 42, four engagement protrusions 73b are formed at equal intervals in the circumferential direction of the cylinder main body 73a. As shown in FIG. 4, these engaging convex portions 73 b are fitted in and locked into engaging concave portions 72 c of the head main body 72. That is, by incorporating the upper end opening 73 c of the locking cylinder 73 into the head main body 72, the engaging convex part 73 b is fitted into the engaging concave part 72 c and the upper end of the locking cylinder 73 is engaged with the head main body 72. By pressing against the stop piece 72e, the pressing head 71 is formed. The pressing head 71 is attached to the stem 42 by fitting the cylinder main body 73 a of the locking cylinder 73 to the upper end of the stem 42 and locking the upper end opening 73 c to the upper end of the stem 42.

  Even in the volatilization device 70 provided with such a two-part pressing head 71, it functions in the same manner as the volatilization device 10 shown in FIG. That is, when the pressing head 71 is pressed down and the stem 42 is lowered and the volatilizing agent K is discharged from the upper end opening 42a of the stem 42, the discharged volatilizing agent K collides with the dispersion protrusions 72d, thereby causing the radial direction. Guided outside. And after colliding with the inner surface of the top wall part 72b, it rebounds and falls through between the locking pieces 72e and 72e and between the engaging convex parts 73b and 73b. At this time, since the cylindrical portion 72a is disposed in the upper cylinder 40d in this example, the dropped volatile agent K is temporarily stored between the stem 42 and the upper cylinder 40d, and then overflows through the slit hole 45. It is stored in the storage recess 44. Thereby, the volatilizing agent K is uniformly impregnated in the impregnated body 14.

As described above, even in the volatilization apparatus 70 of this example, the volatilizing agent K stored in the storage recess 44 is brought into direct contact with the impregnating body 14 and impregnated, so that the volatilizing agent K is evenly immersed in the impregnating body 14 evenly. Can be embedded. Therefore, the volatilizing agent impregnated in the impregnated body by the air blown onto the impregnated body 14 can be vaporized evenly and efficiently.
Further, since the pressing head 71 is a two-part member made up of the head main body 72 and the locking cylinder 73, the upper end portion of the stem 42 can be firmly held by the cylinder main body 73a of the locking cylinder 73, and accordingly. The connection strength between the stem 42 and the pressing head 71 can be increased.

Further, the pressing head may be a one-part member having a hinge structure, instead of being formed by two-part members as shown in FIG. For example, a pressing head having the following configuration can be employed.
That is, it is formed in a cylindrical shape continuously extending over the entire circumference, and is provided with a mounting portion mounted on the stem 42, a peripheral wall portion surrounding the mounting portion from the outside in the radial direction, and spaced apart in the circumferential direction. And a connecting piece for connecting the mounting portion and the peripheral wall portion, and the peripheral wall portion in a state of being connected to the main body cylinder via a hinge and having a gap between the upper end opening of the mounting portion. A pressing head having a top wall portion that closes the upper end opening can be employed.

  Here, the hinge that connects the main body cylinder and the top wall portion is, for example, a narrow-width connecting portion formed thin. Therefore, when molding such a pressing head, the top wall and the body cylinder are integrally molded with the top wall being opened 180 ° around the hinge so that the upper opening of the body cylinder is fully open. Then, it can be formed in a form in which the upper opening of the main body cylinder is covered with the top wall portion by bending the hinge portion. In other words, it can be formed in substantially the same configuration as the one-part pressing head 43 shown in FIG. 1 or the two-part pressing head 71 shown in FIG.

  When such a pressing head is adopted, the entire pressing head can be formed as one part because it is integrally formed. And since the mounting part mounted | worn with the stem 42 is formed in the cylinder shape extended continuously over a perimeter, the mounting force of the pressing head with respect to the stem 42 can be raised. Further, since the top wall portion and the main body cylinder can be integrally formed with the top wall portion opened without covering the upper opening of the main body cylinder, the volatilizing agent K discharged from the upper end opening 42a of the stem 42 is supplied to the pressing head. Can be easily realized without complicating the mold structure, for example, the core can be removed in one direction, for example, the core can be dropped onto the top surface of the mounting cap. it can.

Moreover, in the said embodiment, although the impregnation body 14 was formed in the cylindrical shape coaxial with the said axis O, this invention is not limited to this, For example, an impregnation body is the back wall part 21, the discharge container 13, and You may form in the plate shape arrange | positioned between.
Moreover, in the said embodiment, although the case where it arrange | positions and uses a volatilization apparatus in front of the ventilation openings, such as a vehicle, the volatilization apparatus of this invention is not limited to this, For example, on the table in living space, It can also be used by placing it in a suitable place outdoors.
