[Industrial applications]

 According to the present invention, a liquid container provided with an absorbent core for filling a liquid and sucking the liquid, a container for housing the liquid container, and a liquid container provided in the container to heat the absorbent core. The present invention relates to a heating evaporation device having a heating means for evaporating a liquid to the outside of the body, and particularly to a device suitable for mosquito repellent and insecticidal.

[0002]

[Prior Art]

 Conventionally, for insecticide, deodorization, etc., for example, insecticides, bactericides, acaricides, repellents, pharmaceuticals, fragrances, cosmetics, etc. are appropriately vaporized and evaporated in the room. There are various methods of vaporization and evaporation here, but as a method suitable for maintaining the effect of evaporation for a long period of time, a liquid to be evaporated, that is, an insecticide or the like is stored in a container and the liquid is evaporated. There is a heating evaporation device configured so that the immersed liquid absorbent core is pulled out from the neck of the container and heated by an appropriate heating means to evaporate the absorbed liquid.

FIG. 12 is a schematic configuration diagram schematically showing a structural example of a conventional heating evaporation device, in which 1 is a body formed of synthetic resin or the like, 2 is an evaporation port, 3 is heating means, and 4 is an absorbing member. Liquid core 5 is a container for containing a liquid body. A power cord for energizing the heating means 3, a fixing structure of the heating means 3, a display means for displaying energization, a power switch, and a locking structure of the closing member 1a are omitted for convenience of illustration. In the illustrated heat evaporation apparatus, the container 5 is configured to be loaded from the bottom surface of the container 1, and the container 5 is housed in the container with its bottom portion being positionally regulated by the wall surface 1b of the closing member 1a. Most of the bottom of the body is closed by the closing member 1a. Although it is different from the one shown in FIG. 12, it has a structure in which there is no member for closing the bottom and the container 5 is held by other means, and a relatively large opening is provided at the bottom of the container. Some have been formed. However, according to the study by the inventor of the present application, it was revealed that the heating evaporation device having the above-mentioned structure has a problem to be further improved.

[0004]

[Problems to be solved by the device]

 That is, in a structure in which the bottom of the body 1 is opened without a member that substantially closes the bottom, the number of parts is reduced and the cost is improved because the closing member is not required. However, even when the container 5 is loaded, an opening that communicates with the loading portion 1A in the up-down direction is formed, and a fine or elongated object may undesirably enter the container 1 from there. If metal pieces or the like are present in this intruder, there is a danger that internal wiring or terminals will be short-circuited and an accident will occur. In addition, an infant may insert a driver, etc., which may lead to an electric shock. On the other hand, the structure that closes the bottom of the container body 1 is excellent in that the above-mentioned inconvenience can be prevented, but the number of parts and the number of work steps are both increased, and the replacement of the container 5 is troublesome. There is a problem. Further, in the structure having the closing member 1a, it is necessary to cover the entire container 5 with the container 1 and to provide a space for the intake of air for installing the heating means 3 and the like in the container 1. Therefore, the container 5 inevitably becomes small. Therefore, the amount of liquid to be filled is limited, and the number of times the container 5 is replaced increases. The present invention has been made in view of the above-mentioned problems, and its purpose is to block the bottom of the vessel without increasing the number of parts and the number of working steps, and to perform the heating transpiration well. An object is to provide a device and a liquid container with good operability.

[0005]

[Means for Solving the Problems]

 The object of the present invention is to provide a liquid container that is filled with a liquid and has an absorbent core for sucking up the liquid, a container that houses the liquid container, and a container that is provided in the container. A heating and vaporization device comprising a heating means for heating the liquid core and evaporating the sucked-up liquid to the outside of the container, wherein at least a part of the liquid container closes the bottom opening of the container. This can be achieved by a heating evaporation device characterized by the above.

In addition to the above-mentioned structure, the same object of the present invention is achieved by a heating evaporation device in which an air intake for promoting the heating evaporation is formed in a part of the container or the liquid container. Can be achieved. Further, the above-mentioned other object of the present invention is achieved by a liquid container applied to the above heat evaporation device, characterized in that a recess for operating the liquid container is formed on the lower surface of the liquid container. be able to.

[0007]

[Action]

 According to the above-mentioned configuration, since the bottom opening of the body is closed by the container, it is not particularly necessary to provide a closing member, which not only facilitates simplification of the structure of the heating evaporation device, but also its safety. Therefore, it is possible to mount a liquid container with a large liquid storage capacity without increasing the size of the container. Further, since the air intake port is formed, the heat vaporization of the liquid can be kept excellent. Further, since the concave portion for operating the liquid container is formed on the lower surface of the liquid container, it is possible to enhance the operability when the liquid container is attached to the container or taken out.

[0008]

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIG. 1 is a cross-sectional view of a main part schematically showing the structure of a heating evaporation device to which the present invention is applied. In the description of the embodiments, the same parts as those of the conventional structure are designated by the same reference numerals and the description thereof will be omitted. To do. The heating evaporation device A has a container 5 filled with a liquid, which is housed inside a vessel 1 which can be said to be a shell type when viewed from the side. The container body 1 is made of synthetic resin integrally formed with a transpiration port 2 formed at the center of the upper part and a concave portion 11 corresponding to the air intake port in the present invention formed at the lower circular edge.

The bottom of the container 5 is a so-called closed portion 5B having a larger diameter than the cylindrical portion 5A on the upper side of the container. The diameter of the closed portion 5B is substantially the same as the diameter of the lower circular edge portion of the body 1. Therefore, when the entire container 5 is covered with the container 1, the lower circular edge of the container 1 rides on the closed portion 5B of the container 5. However, since the lower circular edge of the body 1 is formed with, for example, a notch-shaped recess 11, the inside and outside of the body 1 are not completely blocked, and the recess serving as an air intake port is not formed. Air comes to flow through 11.

Next, the container 5 will be described. As shown by the dotted line in FIG. 1, the container 5 is formed so that the liquid is filled also in the closed portion 5B. Moreover, since the bottom surface of the closing portion 5B has a flat plate shape and covers the entire lower opening of the body 1, it also functions as a substantial closing means. That is, the container 5 functions as a liquid container, which is the original purpose, and as a closing member at the bottom of the container 1. By using the container 5 for multiple purposes in this way, the closing member as an independent member becomes unnecessary, and the entire lower opening of the body 1 is closed, so that the infant accidentally touches the finger. It is possible to prevent the risk of being plugged in.

Next, the evaporation operation will be described. The lower end of the liquid absorbent core 4 is formed so as to reach the bottom of the container 5 as shown by the dotted line in FIG. 1, and the lower end is immersed even if the liquid amount decreases. It is designed so that it can be sucked up without fail. On the other hand, the upper end of the liquid absorption core 4 is formed so as to reach the evaporation port 2, and a heating means 3 is provided around the liquid absorption core 4. When the heating means 3 generates heat, the liquid absorbent core 4 is heated, and the sucked liquid is vaporized and diffused from the evaporation port 2, so that insecticide, aroma and the like are performed.

When such evaporation is performed, the temperature inside the body 1 rises due to the heat generated by the heating means 3, so that the air outside the body 1 is easily sucked into the body 1 through the recess 11. In other words, due to the chimney effect, an air flow that flows upward in the container body 1 is formed, and the evaporation can be effectively performed. Further, when the liquid is reduced by heating and evaporating for a long period of time, the liquid amount can be visually observed through the closed portion 5B. Therefore, it is not necessary to provide a window or an illumination means for visually observing the liquid amount, and the bottom of the container 5 acts as a closing member for the container 1, which is extremely effective for downsizing and simplification of the entire device. Can be achieved.

Here, materials and the like of the heating means 3 and the liquid absorbent core 4 will be described. As the heating element as the heating means 3 used in the above-mentioned device, an electric heating type heating element using a semiconductor or a nichrome wire or the like which generates heat by energization is generally used, but the heating element is not limited to this. However, any known heating element such as an air oxidation heating material or a heating material using a platinum catalyst may be used.

As the liquid absorbent core 4, for example, 160 parts by weight of pearlite and 20 parts by weight of wood flour, 20 parts by weight of starch and water are added, and the mixture is kneaded and then extruded and dried (diameter 7 mm × length 71 mm, oil absorption speed). (About 14 hours) can be used, and the optimum shape of the heating means 3 for the liquid absorbent core 4 having this shape is preferably an inner diameter of 10 mm and a thickness of about 10 mm. Further, the liquid absorbent core 4 is not limited to the above, and may be formed by appropriately molding an organic or inorganic material, or may be a fibrous material not limited to a solidified powdery material.

When the heating means 3 and the liquid absorbent core 4 have the above-described shapes, the gap between the peripheral surface of the liquid absorbent core 4 and the inner diameter of the heating means 4 is 3 mm, but it depends on the type of liquid in the container 5. The gap between the liquid-wicking core 4 and the heating means 3 can be set in the range of 0, 5 mm to 4 mm so that an appropriate heating temperature can be obtained. The amount of protrusion of the liquid absorbent core 4 from the upper surface of the heating means 3 is set to about 1,5 mm, and the distance between the lower surface of the heating means 3 and the upper end surface of the container 5 is set to about 8,5 mm 2. The amount of protrusion of the liquid absorbent core 4 from the heating means can be freely set within the range of 1,5 mm ± 3 mm.

The container 1 and the container 5 may be engaged with each other simply by placing the container 1 on the container 5 in order to accurately position the heating means 3 and the liquid absorbent core 4. For example, as shown in FIG. 8, a plurality of pairs of engagements of a locking piece 5C projecting on the upper side surface of the closed portion 5B of the container 5 and a projection 10 projecting inside the lower end of the body 1 are formed. It is desirable to lock the container 1 and the container 5. Note that this engagement is not limited to the configuration shown in FIG. 8, and the locking piece 5C may be formed so as to be appropriately upright on the upper surface side (not shown) instead of the side surface of the closing portion 5B. Further, the structure for accurately positioning the heating means 3 and the liquid-wicking core 4 is not limited to the structure shown in FIG. 8, and various structures can be adopted. For example, as shown in FIG. The locking piece 20 may be formed on the upper part of the body so as to be elastically pushed into and engaged with the screw portion of the neck portion, or may be screwed at this portion. As described above, in this embodiment, since the closed portion 5B which is the bottom portion of the container 5 is exposed on the surface of the container body, the residual liquid amount in the container can be confirmed without providing the illumination means in the apparatus. This is extremely easy to do.

Next, a second embodiment will be described with reference to FIG. The difference between this embodiment and the first embodiment is that the container 5 is formed in a conical shape. Therefore, members having the same functions as those in the above-mentioned embodiment are designated by the same reference numerals and the description thereof will be omitted. Further, as the engaging structure between the container 5 and the container 1, for example, the structure shown in FIG. 8 or 9 can be adopted. The bottom surface diameter of the container 5 shown in FIG. 2 is set so as to cover the entire lower opening of the container 1, and the side surface is formed as an inclined surface toward the extraction portion of the liquid absorption core 4 provided on the upper portion. It has a conical shape as a body. And, the lower opening edge of the body 1 is provided with recesses 11 serving as air intakes at appropriate intervals so that when the container 5 is covered with the body 1, the lower opening edge is caught on the slope of the container 5. It is configured.

Accordingly, when the container 5 is covered with the container 1 as shown in the drawing, the inside and outside of the container 1 become more breathable due to the recessed portion 11, and when the heating means 3 is energized, the liquid is vaporized and evaporated. And can be promoted. However, even if an elongated object is to be inserted from the recessed portion 11, safety is improved because it cannot be inserted unless it is bent artificially. Further, the entire bottom part of the container 1 is closed by the flat bottom surface of the container 5, so that the stability is also improved. Further, since the side surface of the container 5 in this embodiment is a so-called tapered surface whose diameter gradually increases toward the bottom side, when the container 5 is mounted on the container 1, the container 5 and the container side surface are Due to the guiding action by the contact with the lower end portion of the body 1, the liquid absorbing core 4 can be easily inserted into the heating means 3.

Next, a third embodiment will be described with reference to FIG. In this embodiment, the container 5 shown in the first embodiment is referred to as a cordless type, and the members having the same functions as those in the respective embodiments are designated by the same reference numerals and the description thereof will be omitted. To do. The bottom of the container 5 shown in FIG. 3 is formed in the closed portion 5B as described in the first embodiment. On the other hand, the diameter of the lower opening of the body 1 is formed to be smaller than the diameter of the closed portion 5B, but the difference between the diameters of the two is different from the fixed portion 13 of the insertion plug 12 fixed to the side surface of the body 1. It is set according to the height of. Therefore, the tip end surface of the fixed portion 13 and the outer peripheral surface of the closed portion 5B have substantially the same radius. When the plug 12 is inserted into the outlet 22 provided on the wall 21 or the like and the heating means 3 is energized to perform heat evaporation, the outer peripheral surface of the closed portion 5B contacts the surface of the wall 21 and the device In the illustrated example, the plug 12 is prevented from rotating, and the plug 12 is prevented from coming off. As described above, also in this embodiment, since the closed portion 5B which is the bottom portion of the container 5 is exposed on the surface of the container body, the residual liquid amount in the container can be confirmed without providing a lighting means in the apparatus. This is extremely easy to do.

As the engagement structure between the container 5 and the body 1, for example, a structure in which the screw part of the neck of the container 5 is screwed into the locking part 20a having a female screw part or the elastic structure shown in FIG. Any engaging structure can be employed. In addition, since the concave portion 11 serving as an air intake is formed at the lower opening edge of the container body 1, the heat evaporation can be promoted in the same manner as described above. Further, since the lower opening of the body 1 is closed by the closing portion 5B, it is not necessary to provide a special closing member as in the above, and the structure can be simplified.

Next, a fourth embodiment will be described with reference to FIGS. 4 and 5. The difference between this embodiment and each of the above-mentioned embodiments is that a recess serving as an air intake is formed in the closed portion 5B. That is, the closed portion 5B is formed in the container 5 as in each of the above-described embodiments, but the double recessed portion 15 is formed in a groove shape on the upper surface of the closed portion 5B as shown in the figure. On the other hand, the concave portion 11 serving as an air intake is not formed at the lower opening edge portion of the container body 1, and the lower portion of the container body 1 has an annular shape having the same plane. As the structure for engaging the container 5 and the body 1, for example, the structure shown in FIG. 8 or 9 can be adopted. However, when the container 1 is placed on the closed portion 5B to cover the entire container 5, the air intake port is formed between the edge of the container 1 and the two recesses 15, so As in the example, heat evaporation can be promoted. Moreover, since the opening of the container 1 is closed by the closing portion 5B, it is not necessary to provide a special closing member, and the structure can be simplified. Further, it is difficult to insert an elongated object, and safety can be improved. Also in this embodiment, since the closed portion 5B, which is the bottom portion of the container 5, is exposed on the surface of the container, it is possible to check the residual liquid amount in the container without providing any lighting means in the device. Can be done very easily.

Next, a fifth embodiment will be described with reference to FIG. The feature of this embodiment is that the bottom of the container 5 is formed with a recess and a vent hole is formed in the body 1. That is, a knob 16 formed by two concave portions is formed on the bottom surface of the container 5, and when the closing portion 5B is fitted into the lower opening of the body 1 to engage with or disengage from the lower opening of the body 1, the work can be easily performed with fingers. Has been devised. By the way, in the structure of this embodiment, since the closing portion 5B is fitted in the lower opening of the body 1, even if the recesses 11 and 15 are formed, the air intake is not formed. Therefore, the ventilation holes 17 are formed at desired intervals on the side surface of the body 1 at a height position where the closed portion 5B is not covered. The body 1 and the container 5 are appropriately integrated by the above-described elastic engagement by fitting, screwing, or the like.

According to this configuration, since the lower opening of the container 1 is closed by the container 5, it is not necessary to provide a closing member in particular, and since the ventilation hole 17 is formed, the transpiration action is also excellent as in the above. Done. Further, since the knob 16 is formed, the container 5 can be easily replaced, and since the area required for the knob 16 is small, the bottom surface of the closing portion 5B becomes a flat plate as a whole, and the device A The whole can be placed stably.

Further, in the container 5 shown in the fifth embodiment and the present embodiment shown in FIG. 6, the position and size of the knob 16 (recessed portion) are shown in FIG. 12 as shown in FIG. By making it correspond to the protrusion 1b of the closing member 1a, it can be applied to the body of the conventional structure shown in FIG. Further, the knob 16 shown in the present embodiment may be annular or intermittently formed on the entire outer periphery of the bottom surface of the closing portion 5B. As described above, the container 5 of the present embodiment can be used for a conventional container, has extremely high versatility, and has an economic advantage.

Next, a sixth embodiment will be described with reference to FIG. The feature of this embodiment is that the knob 16 is provided on the outer periphery of the bottom surface of the closing portion 5B. That is, in this embodiment, the knobs 16 having the two recesses are provided on the outer periphery of the bottom surface of the closing portion 5B to increase the distance between the knobs 16 (concave portions). As a result, when the container 5 is fitted into the lower opening of the body 1, it is easy for the fingers to put on it and the workability is improved. Since the ventilation holes 17 are formed on the side surface of the body 1, the heat evaporation can be performed satisfactorily as in the above embodiment. Further, although the knob 16 is provided on the bottom surface of the closed portion 5B, it is sufficient if at most two recesses are formed, so that the flatness of the entire bottom surface is not impaired and the entire apparatus A is stabilized. Can be placed.

Next, a seventh embodiment will be described with reference to FIG. In the construction of this embodiment, the construction of the container 5 is different from the construction of the above-mentioned respective embodiments, and the lower part of the container is not large in diameter but is the same in diameter except the neck of the container. The side surface of the container 5 is attached so as to contact the inner wall surface of the container 1. Therefore, not only the positioning of the container 5 at the time of mounting is extremely easy, but also if the lower portion of the container 5 is configured to be exposed to the lower side of the body 1, even in this embodiment, the illumination in the device is achieved. It is extremely easy to check the residual liquid amount in the container without providing any means. Furthermore, an air intake is formed by appropriately forming a groove-shaped recess on the entire side surface of the container 5 in the vertical direction, or by forming a groove-shaped recess on the inner wall surface of the body 1 as well. be able to.
