Description

  The present invention relates to a chemical liquid volatilizer that volatilizes a chemical liquid such as a liquid deodorant or fragrance contained in an external space, and particularly relates to a chemical liquid volatilizer that can easily replenish the chemical liquid.

  In order to eliminate the discomfort caused by odors in rooms and automobiles and create a comfortable space, chemical liquid volatilizers that volatilize liquid chemicals such as liquid deodorants and fragrances to the outside are widely used. The chemical volatilizer generally has a chemical solution container that stores the chemical solution and a core member (liquid absorbing core) that is immersed in the chemical solution (see, for example, Patent Document 1). The upper end of the core member is exposed to the external space from the upper opening of the chemical solution container, and the sucked chemical solution is volatilized into the external space. The core member is held by a holding member attached to the upper opening of the chemical solution container.

  In the chemical liquid volatilizer described in the above-mentioned Patent Document 1, when the chemical solution in the chemical solution container becomes small and an attempt is made to replenish the chemical solution, the top opening of the chemical solution container can be poured from the top opening of the chemical solution container. It is necessary to remove the holding member with the core member attached to the. At this time, if the core member is wet with the chemical solution, the chemical solution may adhere to the hand during removal. In addition, a place to place the removed holding member with the core member is required, and when it is directly placed on a desk or floor, the chemical solution may drip from the core member and adhere to household goods.

  Thus, a chemical liquid volatilizer has been proposed that can replenish the chemical liquid in the chemical liquid container without removing the core member (holding member) (see, for example, Patent Document 2). As shown in FIG. 17, the chemical volatilizer described in Patent Document 2 has a funnel portion 103 for replenishing a chemical solution on a holding member 101 provided in an upper opening 106 of a chemical solution container 105 to hold the core member 102. Is formed. The holding member 101 is attached with a flange portion 104 at the upper end engaged with an upper edge portion of the neck portion 110 of the chemical solution container 105. The core member 102 is inserted and held in the cylindrical portion 107 at the lower end of the funnel portion 103. The cylindrical portion 107 has a large-diameter portion 107A at the upper portion, and a plurality of openings 108 through which the chemical solution replenished to the funnel portion 103 flows out. In the figure, 109 is an air hole.

The neck portion 21 has a shape in which a small-diameter portion 21A having an upper opening 20 at the upper end and a large-diameter portion 21B having a slightly larger diameter than the small-diameter portion 21A are continuously provided up and down. A first male screw portion 23A and a second male screw portion 23B are provided on the outer peripheral surfaces of the small diameter portion 21A and the large diameter portion 21B, respectively.

  The core member 3 is mainly composed of fibers excellent in sucking up the chemical solution and volatilizing the chemical solution, and is formed in a rod shape as a whole. The core member 3 is held by the holding member 4 so that the lower end portion thereof can come into contact with the bottom surface of the chemical solution container 2 and at least the upper end portion is exposed above the holding member 4. The shape of the core member 3 is not particularly limited as long as the chemical liquid can be sucked up, and can be an arbitrary shape such as a tubular shape or a honeycomb shape. Moreover, as said fiber layer which forms the core member 3, natural fibers, such as a vegetable fiber and a pulp, synthetic fibers, such as felt, cotton, rayon, polyester, PET (polyethylene terephthalate), PP (polypropylene), or those mixtures It can be comprised with fibrous materials, such as a fiber. The core member 3 may be formed of a single resin (for example, Duracon). A transpiration mat may be provided so as to contact the upper end (exposed portion) of the core member 3, and the chemical liquid sucked up by the core member 3 may be spread over the entire transpiration mat to evaporate the chemical liquid.

  The holding member 4 is provided in the upper opening 20 of the chemical liquid container 2 and holds the core member 3 in the chemical liquid container 2 with at least the upper end portion of the core member 3 exposed upward.

The holding portion 43 has an insertion port 44 for inserting the core member 3 and a cylindrical clamping portion 45 extending downward from the periphery of the insertion port 44, and the clamping portion 45 has an outer diameter of the core member 3. It has a slightly smaller inner diameter. When the core member 3 is inserted by being inserted into the holding portion 45 from the insertion port 44, the core member 3 is elastically deformed and presses the inner peripheral surface of the holding portion 45. As a result, the core member 3 becomes the inner peripheral surface of the holding portion 45. Contact with. Thereby, the core member 3 is held at a predetermined height position. By adjusting the height position of the core member 3 and changing the length of the core member 3 protruding upward from the holding member 4 and exposed to the external space, the volatilization amount of the chemical solution can be adjusted.

  Around the insertion port 44 of the holding surface portion 40B, at least one injection port 46 (one in the illustrated example) having a predetermined size is formed. Although the details will be described later, the injection port 46 is a supply port for supplying new chemical liquid into the chemical liquid container 2 when the chemical liquid in the chemical liquid container 2 becomes small as the chemical liquid volatilizes. In the present embodiment, since the holding surface portion 40B provided with the injection port 46 is located below the upper opening 20 and is surrounded by the peripheral wall portion 40A, when pouring the chemical solution into the injection port 46 for supplying the chemical solution, Even if the chemical liquid spills outside the injection port 46 (such as on the holding surface portion 40B), it is prevented from flowing out of the chemical liquid container 2. In the present embodiment, the holding surface portion 40B is provided as a horizontal surface, but may be an inclined surface that decreases from the peripheral wall portion 40A toward the insertion port 44. Thereby, when the chemical solution is poured into the injection port 46, the chemical solution spilled on the holding surface portion 40 </ b> B flows toward the insertion port 44, so that it can be absorbed by the core member 3.

  The injection port 46 is formed in an elliptical shape in FIG. 4, but may be a circular shape, a rectangular shape, or a substantially trapezoidal shape as shown in FIGS. 5 and 6. A plurality of injection ports 46 may be formed, and for example, two (see FIG. 5) or four (see FIG. 6) may be formed.

  As a refill container for storing a chemical solution for replenishment, as shown in FIG. 8, the upper corner 70 is picked with a finger and twisted to form the portion as a liquid spout 71. A refill container 7 of a type called a pouch is generally employed. Therefore, in order to smoothly refill the liquid in the refill container 7 without spilling into the chemical liquid container 2, the inlet 46 of the refill container 7 is placed in the inlet 46. It is preferable that the insertable size is larger than the spout 71 of the refill container 7. Specifically, the spout 71 of such a refill container 7 generally has a substantially elliptical shape with a horizontal width d1 of about 5 mm to 20 mm and a vertical width d2 of about 0.5 mm to 5 mm when liquid is poured out. It becomes. Moreover, in order to make it easy to pour out liquid from the spout 71, there are many ones in which the opening shape of the spout 71 is maintained in a circular shape or an elliptical shape. In particular, the horizontal width d1 is about 5 mm to 20 mm, and the vertical width d2 is about 5 mm to 20 mm. Therefore, the inlet 46 is formed such that the maximum lateral width D1 (see FIGS. 4 to 6) is at least 5 mm to 30 mm and the maximum vertical width D2 (see FIGS. 4 to 6) is at least about 2 mm to 30 mm. It is preferable. Thereby, a chemical | medical solution can be inject | poured vigorously in the chemical | medical solution container 2, and an injection | pouring speed | rate can also be raised.

  The cover member 5 is made of synthetic resin, has a circular shape in plan view, and includes an upper surface portion 50 that covers the upper side of the holding member 4 and a circular frame-shaped side wall portion 51 that hangs down from the upper surface portion 50.

Thus, even when the chemical solution container 2 falls down unexpectedly when the chemical vaporizer is used (during chemical vaporization), the lower step portion 50a functions as a lid that closes the inlet 46 of the holding member 4. The chemical solution in the chemical solution container 2 is prevented from spilling from the inlet 46 and flowing out to the outside.

  An insertion port 53 is provided at the center of the lower step portion 50a. The insertion port 53 has a diameter slightly larger than the diameter of the core member 3 and can be inserted through the upper end portion (exposed portion) of the core member 3 protruding upward from the holding member 4. ing. Thereby, even when the cover member 5 is attached to the chemical solution container 2, the upper end portion (exposed portion) of the core member 3 is exposed to the external space through the insertion port 53, so that the chemical solution sucked up by the core member 3 is externally exposed. It can be volatilized in space.

  The cap 6 is for sealing the upper end of the core member 3 exposed to the external space when the chemical volatilizer is not used. The cap 6 is made of synthetic resin, and includes an upper surface portion 60 having a circular shape in a plan view and a circular frame-shaped side wall portion 61 depending from the upper surface portion 60.

Is screwed to the large diameter portion 21B, so that the cap 6 is detachably attached to the chemical liquid container 2 via the cover member 5 and the holding member 4. Thereby, in the state where the cap 6 is attached to the chemical solution container 2, the upper end portion of the core member 3 is sealed in the cap 6 without being exposed to the external space, so that the chemical solution is prevented from being volatilized in the external space. ing.

  In the present embodiment, the upper surface portion 60 of the cap 6 also has a circular shape in a plan view located in the neck portion 21 of the chemical liquid container 2 (immediately above the lower step portion 50a of the cover member 5), like the upper surface portion 50 of the cover member 5. The lower stage part 60a and the cyclic | annular upper stage part 60b which exists in the position higher than the lower stage part 60a in the circumference | surroundings of the lower stage part 60a are provided. And the protruding part 63 which covers the upper end part (exposed part) of the core member 3 is provided in the center of the lower step part 60a, and the upper end part (exposed part) of the core member 3 is sealed substantially without gap. The shape of the upper surface portion 60 of the cap 6 is not necessarily limited to this shape as long as the upper end portion (exposed portion) of the core member 3 can be sealed in the cap 6. For example, the upper surface portion 60 may have a horizontal flat shape.

  According to the chemical volatilizer having the above-described configuration, when the cap 6 is attached to the chemical liquid container 2, the upper end portion of the core member 3 exposed on the holding member 4 is in the cap 6 when not in use as shown in FIG. It is sealed. On the other hand, as shown in FIG. 2, at the time of use, the cap 6 is removed from the chemical solution container 2 so that the upper end portion of the core member 3 comes into contact with the external space above the holding member 4. Thereby, the chemical | medical solution sucked up by the core member 3 is volatilized to external space. When the chemical solution in the chemical solution container 2 becomes small with the volatilization of the chemical solution, the inlet 46 of the holding member 4 is exposed by removing the cover member 5 from the chemical solution container 2 (holding member 4). The chemical solution can be poured into the chemical solution container 2 from the injection port 46.

  As described above, in the chemical liquid volatilizer having the above-described configuration, the chemical liquid can be replenished to the chemical liquid container 2 while the core member 3 and the holding member 4 are attached to the chemical liquid container 2. In addition, since it is not necessary to touch the core member 3 and the holding member 4 during the replenishment operation, the operator's hand is not contaminated with the chemical solution. In addition, since the core member 3 and the holding member 4 are not removed during the replenishment operation, there is no need for a space for placing them, and there is no possibility that the chemical solution hangs down and adheres to a desk or floor. In addition, since the air for the volume of the replenished medicinal solution is appropriately escaped from the medicinal solution container 2 to the external space through the inlet 46 of the holding member 4 and the insertion port 53 of the cover member 5, Separately, the chemical solution can be replenished without delay without providing air holes. Furthermore, since the injection port 46 of the holding member 4 is covered by the cover member 5 during use, even if the chemical solution container 2 is accidentally collapsed during use, the chemical solution in the chemical solution container 2 is discharged from the injection port 46. It can be prevented from spilling out to the outside.

  14 to 16 show still another embodiment of the chemical volatilizer according to the present invention. In the embodiment of FIGS. 1 to 3, 9 to 11, and FIGS. 12 to 13 described above, the cover member 5 is removed from the chemical solution container 2 (holding member 4) when the chemical solution 2 is replenished. However, in the embodiment shown in FIGS. 14 to 16, it is not necessary to remove the cover member 5 when supplying the chemical solution to the chemical solution container 2, and the chemical solution supply operation can be performed more easily. The basic configuration of the chemical volatilizer according to the embodiment shown in FIGS. 14 to 16 is the same as that of the embodiment shown in FIGS. 1 to 3 described above. Thus, a detailed description is omitted. Moreover, FIGS. 14-16 has shown the whole structure of the chemical liquid volatilizer except a cap.

  In the embodiment of FIGS. 14 to 16, an inward latching claw 59 is provided over the entire inner peripheral surface of the side wall 51 of the cover member 5 instead of the female screw portion. In addition, on the outer peripheral surface of the small-diameter portion 21A of the neck portion 21 of the chemical liquid container 2, an engaging step portion 24 is provided over the entire circumference in place of the male screw portion. By hooking the latching claw 59 on the engagement step portion 24, the cover member 5 is placed on the chemical solution container 2 (small diameter portion 21 </ b> A) via the holding member 4, and with respect to the chemical solution container 2 and the holding member 4. The core member 3 is rotatable.

  Further, the spout 10 is formed around the insertion port 53 provided in the center in the lower step portion 50 a of the upper surface portion 50 of the cover member 5. The spout 10 is formed in substantially the same shape as the injection port 46 of the holding member 4, and is positioned on the injection port 46 and substantially coincides with the injection port 46 by the rotation of the cover member 5. .

  Also in the chemical liquid volatilizer of the embodiment of FIGS. 14 to 16, the upper end portion of the core member 3 exposed on the holding member 4 is sealed in the cap when the cap is fixed to the chemical liquid container 2 when not in use. On the other hand, as shown in FIG. 14, the upper end of the core member 3 comes into contact with the external space above the holding member 4 by removing the cap from the chemical solution container 2 in use. Thereby, the chemical | medical solution sucked up by the core member 3 is volatilized to external space. And when the chemical | medical solution in chemical | medical solution container 2 becomes small with volatilization of a chemical | medical solution, the cover member 5 is rotated with respect to the holding member 4, and as shown in FIG. The chemical solution can be poured into the chemical solution container 2 from the spout 10 and the injection port 46 by being stacked on the four injection ports 46. In use (during chemical vaporization), the upper surface portion 50 (lower step portion 50a) of the cover member 5 is closed by shifting the spout 10 of the cover member 5 so as not to overlap the injection port 46 of the holding member 4. It functions as a part and completely covers the inlet 46 of the holding member 4. Therefore, even when the chemical solution container 2 falls down unexpectedly during use, the chemical solution in the chemical solution container 2 can be prevented from spilling from the inlet 46 and flowing out to the outside.

  In addition, as a structure which can perform the replenishment operation | work of a chemical | medical solution, without removing the cover member 5 from the chemical | medical solution container 2 (holding member 4), the cover member 5 is rotated like embodiment mentioned above in FIGS. Thus, the configuration is not limited to the configuration in which the spout 10 of the cover member 5 and the injection port 46 of the holding member 4 are overlapped. For example, a horizontally slidable lid portion and a chemical solution exposed by sliding the lid portion can be injected into the upper surface portion 50 (lower step portion 50a) of the cover member 5 at a position corresponding to the inlet 46 of the holding member 4. A liquid pouring spout may be provided, and the chemical liquid may be poured into the liquid chemical container 2 from the pouring port 46 through the pouring spout by sliding the lid when the chemical liquid is replenished.
