Description

  The present invention relates to a chemical volatilization container that causes a chemical stored in the cartridge to evaporate by rotating a cartridge type chemical container with a motor, thereby exerting an insect repellent effect or a mosquito repellent effect.

This kind of chemical volatilization container has already been proposed by one of the applicants of the present invention.
Specifically, a method has been employed in which a cartridge bearing hole is directly inserted into the output rotation shaft of the motor. In other words, when exchanging the drug impregnated body stored in the cartridge, the cartridge is pulled out from the motor shaft and taken out from the chemical volatilization container, the cartridge lid is opened, and a new drug impregnated body is stored. The hole for the bearing was set by directly inserting into the output rotation shaft of the motor.

  Since these conventional products promote the volatilization of the drug by air current without heating, there is no risk of burns during use, and a certain amount of the drug can be volatilized stably over a long period of time. In addition to being able to have a simple structure, it is possible to improve the volatilization efficiency without weakening the airflow, and it is a very advantageous container for practical use.

  However, this conventional product has been found to have several improvements in the course of research for further improving usability, and it has been found that convenience can be further improved by satisfying these improvements.

That is, in this conventional product, a high dimensional accuracy is required for the bearing hole of the cartridge in order to directly insert and remove the cartridge from the output rotation shaft of the motor. If the shaft diameter does not match the hole diameter, the rotation of the shaft cannot be transmitted to the cartridge, or the hole cannot be inserted into the shaft. Generally, a container by injection molding is required, such as a mold fee or a product. Led to an increase in costs. Also, when the consumer uses it, that is, when the drug-impregnated body is stored in the cartridge, removed, or replaced, the cartridge must be carefully set on the output rotation shaft of the motor or pulled out each time. In other words, the work of exchanging the drug-impregnated body was troublesome.

  The present inventors have made various studies in order to solve the problems of the conventional products. As a result, when a holder for receiving the drug-impregnated body was permanently set on the output rotation shaft of the motor, and a method in which a cartridge loaded with the drug-impregnated body was attached to this holder was adopted, I'm able to clear the problem well, so I suggest it here.

  Accordingly, an object of the present invention is to enable easy mounting and dismounting of a drug impregnated body and to manufacture and sell it at a very low cost.

In order to solve the above technical problem, a drug volatilization container according to claim 1 of the present invention is a drug volatilization container configured to volatilize a drug from a drug impregnated body by rotation of an output rotation shaft of a motor. a cartridge holder that is integrated with the output rotary shaft is pre mounted on the output rotary shaft of the motor, Ri Do and a medicament cartridge that is detachably mounted wear the cartridge holder, the said cartridge holder said medicament cartridge engagement claws as simple locking means to engage freely disengaged to is shall be provided integrally.

According to the configuration as described above, the cartridge holder is always mounted in advance on the output rotation shaft of the motor. Therefore, it is not necessary to remove the cartridge holder from the chemical volatilization container. A drug cartridge loaded with a drug-impregnated body is attached to the cartridge holder via an engaging claw as simple locking means. When the medicine is completely volatilized from the medicine impregnated body, the medicine cartridge is taken out from the cartridge holder by disengaging the engaging claw as the simple locking means. Then, the medicine cartridge itself is replaced with a new medicine cartridge, or the medicine cartridge is refilled with a new medicine impregnated body, and this is loaded into the cartridge holder. In this way, since the cartridge holder for storing the medicine cartridge loaded with the medicine impregnated body is constantly set on the output rotation shaft of the motor, the output rotation of the motor is rotated every time the cartridge holder is replaced with the medicine impregnated body. There is no need to remove it from the shaft or reinsert it.

Therefore, this invention has the following effects.
As described above, the chemical volatilization container according to claim 1 of the present invention does not need to be removed from the output rotating shaft of the motor or inserted again every time the cartridge holder is replaced with the chemical impregnated body. As a result, the medicine cartridge itself that is used after being exchanged many times does not require high dimensional accuracy, and can be manufactured by light-weight and low-cost vacuum forming or the like. In addition, the consumer can replace the chemical-impregnated body by a simple operation such as placing a lightweight drug cartridge on a cartridge holder previously set in a drug volatilization container.

In addition, conveniently mounted drug cartridge by the cartridge holder, on which removable, the medicine cartridge can be securely held in the cartridge holder during actuation, Ru can be further enhanced volatilization efficiency.

According to the present invention, as described in claim 2 , the medicine cartridge includes a main body and a lid, and includes a support for forming a ventilation gap between the two at predetermined intervals in the circumferential direction. It is desirable.
This is because the volatilization of the drug is effectively promoted from the ventilation gap, and the volatilization of the drug can be efficiently performed.

Further, in the present invention, as described in claim 3 , it is desirable that the main body and the lid of the medicine cartridge are provided with an engaging recess and an engaging protrusion that are detachably engaged with each other.
This is because the contained medicine impregnated body can be accurately held in the medicine cartridge to enhance the volatilization effect of the medicine, and the medicine cartridge can be used any number of times, thereby contributing to resource saving and cost reduction.

  The purpose of enabling easy mounting and dismounting of the drug-impregnated body and enabling it to be manufactured and sold at a very low cost has been achieved with a much simpler structure and at a lower cost.

  A first embodiment of the chemical volatilization container according to the present invention will be specifically described below with reference to FIGS.

FIG. 1 is an exploded perspective view, partly cut away, of a chemical volatilization container according to the first embodiment.
The chemical volatilization container 1 includes a receiving recess 2 and a battery 3 and a motor 4 driven thereby. The output rotation shaft 5 of the motor 4 is configured to protrude in the center of the receiving recess 2. In a state in which the cartridge holder -6 in the recess 2 received is accommodated, the cartridge holder -6 is mounted is permanently integrated with the output rotary shaft 5. Moreover, medicament cartridge 8 to drug-loaded body 7 is loaded to the cartridge holder -6 is placed. The drug cartridge 8 is covered with a lid 9 attached to the main body 10 of the drug volatilization container 1 so as to be freely opened and closed. Furthermore, the main body 10 of the chemical volatilization container 1 is provided with a power switch 11 for controlling the driving / stopping of the driving means including the built-in motor 4 and battery 3. In addition, a holder (not shown) is provided on the back surface of the main body 10 so as to be attached to clothes or the like, and a hanging part (not shown) is provided on the upper portion of the main body 10 and is lowered from the neck through a string or the like. Can do. This is to facilitate the carrying of the chemical volatilization container 1.

As shown in FIGS. 1, 3 and 6, the cartridge holder 6 has an annular peripheral frame 12 and a fitting shaft portion 13 of the shaft core portion. Further, the peripheral frame 12 and the fitting shaft portion 13 are connected by spokes 14. They are connected together. The peripheral frame 12, the fitting shaft portion 13, and the spoke 14 are integrally formed by injection molding. The peripheral frame 12 is composed of a ring body, the fitting shaft portion 13 is formed in a circular shape protruding upward at the shaft core portion, and a fitting hole 15 for fitting to the output rotating shaft 5 is provided at the center of the back surface. It has been. In addition, as a form of this fitting shaft part 13, as shown to (1), (2) of FIG.3 (D), it is set as a triangle shape, a cross shape, etc. in the meaning which prevents malfunctions, such as idling. Is preferred. The fitting between the output rotating shaft 5 and the fitting hole 15 needs to be strong to the extent that they do not slip each other when the motor 4 is driven. Therefore, ideally, it is desirable that they are integrally connected to each other by an adhesive means or the like. However, it is not always necessary to integrate them, and a friction member such as rubber is fitted in the fitting hole 15, A means for increasing the friction between the output shaft 15 and the output rotating shaft 5 to make it difficult to slip can also be adopted. In any case, a configuration in which both are constantly integrated is desirable. As shown in the figure, the spoke 14 is provided with three pieces waiting for a phase of 120 degrees in the circumferential direction of the fitting shaft portion 13. Although it is three in the example of the figure, it is appropriately selected between 2 and 6 as required. Further, as shown in FIGS. 3A to 3C, the spoke 14 is provided with a concave groove 14A that is open upward over its entire length. The purpose is to increase the strength of the spoke 14 itself and to increase the strength of the cartridge holder 6 by making the cross section irregular.

  Further, an engaging claw 17 as an example of simple locking means 16 for locking and holding the medicine cartridge 8 is integrally extended from the peripheral frame 12 upward in the cartridge holder 6. The engaging claw 17 includes a leg portion 17A that is continuous with the peripheral frame 12 and a claw portion 17B that protrudes inwardly at the tip of the engaging claw 17, and is integrally molded with other component parts that constitute the cartridge holder 6. Is integrally formed.

  Next, as shown in FIGS. 1, 2, 4 and 5, the drug cartridge 8 is composed of a main body 18 for accommodating and holding the drug impregnated body 7 and a lid 19 fitted to the main body 18, both of which are injection molded. Compared to this, it can be formed by far more economical vacuum forming. This is because the cartridge holder 6 is simply inserted into and removed from the cartridge holder 6 and does not require precise dimensional accuracy like the cartridge holder 6.

  As shown in FIGS. 4 (A) and 4 (B), the main body 18 includes an annular peripheral frame 20 having a cross-sectional shape protruding upward and a lower portion opened over the entire circumference (see FIG. 4 (B)). A horizontal flange 21, which is connected to the inner and outer lower edges and projecting integrally inwardly and outwardly, a fitting shaft part 22 of the shaft core part, a spoke 23 that integrally connects these parts, and a peripheral frame 20 and an inner part It is composed of a lower open column 24 that is integrally raised with a predetermined dimension above the horizontal flange 21. The fitting shaft portion 22 of the shaft core portion is provided with a concave hole 25 having a circular shape with an open bottom. The concave hole 25 has a hole diameter that can be fitted into the fitting shaft portion 13 of the cartridge holder 6 from above. In addition, as a form of this fitting shaft part 22, as shown to (1), (2) of FIG.4 (D) in the meaning which prevents malfunctions, such as idling, the fitting shaft part of the said cartridge holder 6 is shown. It is preferable to have a triangular shape or a cross shape having a size that can be fitted to the shape 13. Further, as shown in FIG. 4A, three spokes 23 are provided at intervals of 120 degrees in the circumferential direction of the fitting shaft portion 22. Although it is three in the example of the figure, it is appropriately selected between 2 and 6 as required. The struts 24 are provided in the same phase in the circumferential direction as the spokes 23 and on the extension lines of the connecting portions with the peripheral frame 20. This is because the attachment strength of the column 24 can be increased. And the upper end of this support | pillar 24 is formed in the flat surface, and is comprised so that the said lid | cover 19 can be mounted easily. Further, as shown in FIG. 4B, a protruding rib 26 as an example of an engaging protrusion that runs in a horizontal direction is provided on the outer peripheral surface of the upper portion of the column 24. A rib 23A is provided at the center in the width direction of each spoke 23 so as to protrude from the bottom to the top over the entire length (see FIG. 4C). The overall strength of the spoke 23 and the main body 18 is increased. Of course, it goes without saying that the upwardly convex shape of the peripheral frame 20 also increases the strength of the main body 18 as a whole.

  As shown in FIGS. 5A and 5B, the lid 19 of the medicine cartridge 8 includes a peripheral frame 27 extending in the vertical direction, a horizontal flange 28 projecting inwardly from its upper edge, and a lower end. A horizontal flange 29 integrally projecting outward from the edge is provided, and the cross section is formed in a crank shape. Also, spokes 30 are integrally provided from the inward horizontal flange 28 toward the shaft core, and the spokes 30 are coupled to each other at the shaft core. As shown in FIG. 5A, three spokes 30 are provided with a phase of 120 degrees in the circumferential direction of the shaft core portion. Although it is three in the example of the figure, it is appropriately selected between 2 and 6 as required. These spokes 30 are integrally formed with ribs 30A that protrude downward from the upper surface over the entire length at the center in the width direction (see FIG. 5C). The strength of the spoke 30 and the strength of the entire lid 19 are increased. Of course, it goes without saying that the crank-shaped cross-sectional shape of the peripheral frame 27 also increases the strength of the entire lid 19.

The important point here is that the peripheral frame 27 is provided with a stepped portion 27A as shown in FIG. That is, this step portion 27A, which is an example of an engagement recess, is slightly below the middle portion of the peripheral frame 27 in the vertical dimension, specifically, from the upper surface of the support column 24 provided on the main body 18 to the protruding rib 26. The position is slightly longer than the vertical dimension, and the lower portion has a smaller diameter than the upper portion. Therefore, when the lid 19 is put on the main body 18, the protruding rib 26 of the main body 18 is elastically engaged above the stepped portion 27A, and the lid 19 is successfully engaged and held by the main body 18. Become. This is to prevent the medicine impregnated body 7 accommodated in the main body 18 from being inadvertently detached along with the rotation of the medicine cartridge 8 and to maintain the accommodation accurately.

Further, as shown in FIG. 6, the vertical dimension of the column 24 of the main body 18 is such that when the main body 18 is covered with the lid 19, the upper surface of the peripheral frame 20 of the main body 18 and the outer frame 27 of the lid 19 are directed outward. A sufficient gap S is set between the horizontal flange 29 and the horizontal flange 29. Specifically, the dimension is set such that the outward horizontal flange 29 of the peripheral frame 27 of the lid 19 comes to approximately half the vertical dimension of the support 24.
That is, the drug impregnated body 7 is accommodated in the main body 18 and the lid 19 is covered, and the drug cartridge 8 thus configured is accommodated in the cartridge holder 6 and forcibly rotated to volatilize the drug in the drug impregnated body 7. However, at this time, the volatilization effect of the drug impregnated body is more effectively performed around the entire area of the drug volatilization container from between the main body 18 and the lid 19 of the drug cartridge 8.

Further, the engaging pawl 17 provided on the cartridge holder 6, the number of posts 24 provided in the drug cartridge 8, further are uniform in phase to provide, optionally together three are provided in the illustrated example, the phase also It is set to 120 degrees.

  1 is a pilot lamp which is turned on when the motor 4 is operated.

  When the drug volatilization container 1 configured as described above is used for the first time, the drug impregnated body 7 is first accommodated in the drug cartridge 8, the drug cartridge 8 is accommodated in the cartridge holder 6, and the engagement claw 17 is also accommodated. The claw portion 17B is locked to the outward horizontal flange 21 of the lid 19 of the medicine cartridge 8 and is securely held in the cartridge holder 6. After that, when the lid 9 of the main body 1 is closed and the switch 31 is turned on to operate the motor 4, the cartridge holder 6 is forcibly rotated by the rotation of the output rotating shaft 5, and the medicine cartridge 8 accommodated and held therein is also Rotate together. As a result, a chemical | medical agent volatilizes from the chemical | medical agent impregnation body 7, a volatilization component is diffused around, and an insect-proof effect is improved.

  On the other hand, when the medicine of the medicine impregnated body is used up, the lid 9 of the medicine volatilization container 1 is opened, and the medicine cartridge 8 is taken out from the cartridge holder 6 while releasing the engagement claw 17 of the cartridge holder 6. Next, the lid 19 of the drug cartridge 8 is opened, the internal drug impregnated body 7 is taken out, a new drug impregnated body 7 is again loaded into the main body 18, and the lid 19 is closed. Thus, the medicine cartridge 8 containing the new medicine impregnated body 7 is mounted on the cartridge holder 6 in accordance with the loading procedure described above.

  The drug cartridge 8 is exemplified as a type in which the drug impregnated body 7 and the container, that is, the main body 18 and the lid 19 can be separated, but a disposable type in which the drug impregnated body 7 is accommodated and integrated in advance. Is also adopted. Specifically, although not shown in the drawing, the top plate, the bottom plate, and the peripheral portion are provided with the ventilation gap S so as to be integrally formed, and the drug impregnated body 7 is preliminarily sealed in the integrated drug cartridge 8. It is.

Moreover, although the thing which employ | adopted the protrusion rib 26 as an engagement convex part and the step part 27A of the surrounding wall 27 as an engagement recessed part was illustrated, in addition to such a structure, on the inner surface of the surrounding wall 27 instead of the step part 27A Protruding ribs that are continuous in a circumferential direction may be used. Further, this projecting rib may be used, and an engaging recess may be provided on the column 24 side instead of the projecting rib 26 so that both are engaged.

  Thus, the chemical volatilization container according to the present invention has a cartridge holder 6 permanently attached to the output rotation shaft 5 of the motor 4, unlike the conventional structure in which the drug cartridge is directly inserted and attached to the output rotation shaft 5 of the motor 4. Since the medicine cartridge 8 containing the medicine impregnated body 7 is inserted into and removed from the cartridge holder 6 through the simple locking means 16, the medicine cartridge 8 that is used any number of times even after replacement is provided. It does not require high dimensional accuracy, and therefore can be sufficiently manufactured by light-weight and low-cost vacuum molding, etc. When a consumer also replaces the drug impregnated body 7, a lightweight drug cartridge 8 is set in the drug volatilization container 1 in advance. The medicine cartridge 8 can be loaded and removed by a simple operation such as placing it on the cartridge holder 6 that is It began to help a lot in reducing the collateral.
