[0003]

[Problems to be solved by the device]

 However, the type that adjusts the position of the chemical liquid bottle has a configuration that uses an adjustment ring and a tank holder, and the user must attach and detach it, and it is also necessary to manage the adjustment ring and the tank holder. Therefore, it is not easy to use. Further, from the viewpoint of manufacturing, the number of parts is large, which results in high cost. Further, in the configuration in which the screwing between the chemical solution hull and the outer container is adjusted, there is a disadvantage that the operation of attaching and detaching the chemical solution bottle is troublesome. Further, in the structure in which the heating element is held by the support and the support is moved and adjusted along the cam groove, the support itself serves as an adjusting means and the engaging portion between the cam groove and the support is Since there is more than one, it is difficult to obtain the accuracy of the fitting relationship, the play of the heating element easily occurs due to the engagement state of the support and the cam groove, and the cam groove and the part that engages with this groove This is not practical because not only the lateral displacement between the liquid-wicking core and the heating element tends to become large due to abrasion, etc., but also the stepwise adjustment by the cam groove makes it difficult to make fine adjustments. . The present invention has been made in view of the above problems, and provides a heating vaporizer that is simple in configuration and that is configured to easily adjust the position of a heating element and vaporize a drug. Especially.

[0004]

[Means for Solving the Problems]

 The object of the present invention is to control the position of the heating element in a horizontal direction in a heating vaporizer that heats an absorbent core protruding from a medicine container with a heating element to evaporate the chemical liquid sucked up by the absorbent core. A guide means for vertically moving is provided, and one operation means is provided in which the operation portion is located outside the outer container that stores the drug container in a fixed state and the other end is engaged with the heating element. This is achieved by a heating vaporizer characterized in that the evaporation of the drug can be adjusted by changing the positions of the liquid absorbent core and the heating element by operating the means. In the present invention, the heating element is not particularly limited and various ones can be used. In the embodiments described later, a ring-shaped heater is used, but this ring-shaped heater uses a nichrome wire. Although an ordinary one constituted by sandwiching an electric heat source such as the above or a sheet-like heater between heat-resistant resins can be used, a positive electrode thermistor using a semiconductor excellent in temperature stability is particularly advantageous. As the liquid absorbent core, it is preferable to use a material that does not deform or expand depending on the evaporating agent used and has heat resistance of around 150 ° C. Specific examples of such liquid core include, for example, Inorganic fibers such as felt core, unglazed core, asbestos core, porcelain porous core, glass fiber, and asbestos hardened with a binder such as gypsum and bentonite, glass powder, kaolin, activated clay, talc, diatomaceous earth, clay , Gypsum, perlite, bentonite, alumina, silica, alumina-silica, titanium, one or more of burned powder of glassy volcanic rocks and mineral powder of glassy volcanic ash, or these powders and wood powder, charcoal powder , Mixtures with activated carbon, such as dextrin, starch, silicone resin, fluororesin, gum arabic, carboxymethyl cellulose, synthetic glue, etc. And the like such as those solidified with a binder. As a particularly preferable liquid absorbent core, 100 parts by weight of the mineral powder and 10 to 300 parts by weight of a mixture of wood powder and carbon powder and / or activated carbon up to an equal weight are mixed, and the whole liquid absorbent is added to the mixture. Examples include those prepared by blending 5 to 25% by weight of the core weight of the binder, further adding water thereto, kneading, extrusion-molding, and drying. The liquid absorbent core preferably has a liquid absorption rate of 1 to 40 hours, preferably 8 to 21 hours. The liquid absorption rate is such that a liquid absorption core having a diameter of 7 mm and a length of 70 mm is dipped from its lower portion to 15 mm in n-paraffin liquid having a liquid temperature of 25 ° C., and n-paraffin reaches the core apex of the liquid absorption core. Means the value determined by measuring the time to. In addition, a dye such as malachite green, sorbic acid and salts thereof, an antifungal agent such as dehydroacetic acid, and the like can be further added to the absorbent core, if necessary. A tungsten bulb may be used as the irradiation lamp, but in order to keep the heat generation of the irradiation lamp as low as possible and prevent the absorption core from being heated and keep the effective volatilization rate of the chemical solution constant, an ultraviolet fluorescent lamp or a neon lamp is used. , It is preferable to use a light emitting diode. In the present invention, the drug solution contained in the liquid container may be any insecticide, bactericide, miticide, repellent, pharmaceutical, cosmetic, etc., as long as it is a substance that vaporizes and evaporates by heating.

[0005]

[Action]

 According to the heating vaporizer, the heating element can be moved accurately without displacement by providing the guide means of the concave and convex fitting that vertically guides the heating element while horizontally controlling the position of the heating element. Further, since one operating means engaged with the heating element does not have a horizontal positioning function but has only a moving function, the heating element can be engaged even if the engagement state is relatively rough. There is no problem with his movement.

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 is a sectional view showing the structure of the heating evaporator, and FIG. 2 is a perspective view showing the external shape. First, the overall structure of the heating evaporator 1 (hereinafter abbreviated as “evaporator”) will be described. The outer container 2 is formed in a substantially cylindrical shape, and the inner space, in other words, the hollow portion is a large container for accommodating the drug container 3. It is formed in a small diameter portion 6 that supports the diameter portion 4 and the heater 5 so as to be vertically movable. The structure of the outer container 2 will be described below. The lower portion is formed with an opening 7 having a large diameter so that the medicine container 3 can be taken in and out, and the opening 7 can be opened and closed by screwing the lid member 8. It has become. Further, a spiral guide groove 9 that guides the heater 5 up and down is formed inside the small diameter portion 6, and a flange portion 10 that acts as a stopper of the heater 5 is formed at the tip of the small diameter portion 6.

The medicine container 3 is formed in a bottle shape using synthetic resin or glass, and the medicine to be filled in the medicine container 3 is selected from the medicines explained before the present embodiment according to the purpose of use. To be selected. The liquid absorbent core 12 is drawn out from the injection port 11 of the medicine container 3 in a rod shape, and the length of the liquid absorption core 12 is determined by the thickness d of the heater 5 and the vertical stroke. In the present embodiment, when the heater 5 is at the uppermost end, it takes about 1/2 of the thickness d 1, and when the heater 5 is positioned at the lowermost end, the liquid absorbent core 12 is surrounded by the entire length. It is set. The lower end of the liquid absorbent core 12 is set to a length such that it comes into contact with the bottom of the drug container 3 so that the liquid can be reliably absorbed even if a very small amount of the drug remains.

The heater 5 is formed by covering the positive thermistor and the like described in this embodiment with a heat-resistant resin and forming an annular shape. The outer surface of the heater 5 has a spiral shape screwed into the guide groove 9. 2 is formed. The operation knob 22 is integrally attached to the top of the heater 5, and the tip of the operation knob 22 projects from the flange portion 10 to the upper portion of the outer container 2. Therefore, when the user rotates the operation knob 22, the heater 5 moves up and down in the small diameter portion 6 while rotating along the guide groove 9. The heater 15 has an annular shape, and the hole 23 formed in the central portion communicates with the central hole of the operation knob 22. Therefore, the transpiration component generated by heating the liquid absorbent core 12 diffuses from the hole 23 to the outside of the outer container 2, that is, the atmosphere. Further, the outer container 2 is appropriately formed with a window 15 through which the amount of the liquid medicine can be visually observed, an air intake 16 for improving the evaporated air flow, and an air flow path 17.

The power supply to the heater 5 is performed by the wiring 24, but since the heater 5 rotates, the following measures are taken. That is, the wiring 24 is formed so as to be embedded in the groove 25 formed inside the outer container 2 as shown by the dotted line in FIG. Further, the wiring 24 and the heater 5 are connected by a lead wire 26. However, if the heater 5 rotates a large number of times, the lead wire 26 may be twisted or entangled with the liquid absorbent core 12. In view of this, in this embodiment, the guide grooves 9 are spaced and a steep slope is formed so that the required stroke can be moved up and down with the number of rotations of the heater 5 being, for example, about one turn. According to this configuration, the heater 5 is not moved from the uppermost position shown by the solid line in FIG. 1 to the edge of the injection port 12 of the drug container 3 until it is stopped by, for example, the operation knob or the protrusion provided on the outer container. Since the number of rotations is about one turn, it is possible to prevent cutting and entanglement due to twisting of the lead wire 26. In this case, since the lead wire 26 of the heater 5 is located on the lower side of the heater, a rotary sliding surface can be provided on the outer peripheral surface of the heater and a predetermined rotation is possible. Although the lead wires 26 are arranged side by side on one side in the drawing, the lead wires may be arranged so as to be separated from each other.

Next, the method of use will be described. In order to reduce the transpiration amount of the drug, the operating knob 22 is operated, in other words, rotated to move the heater 5 to the small diameter portion 6 as shown by the solid line in FIG. Position at the highest position. As a result, the heating amount of the liquid absorbent core 12 is reduced and the evaporation amount is also reduced. By rotating the operation knob 22 to lower the position while rotating the heater 5, the heating amount gradually increases and the transpiration amount also increases. When the heater 5 comes into contact with the edge of the inlet 11 and cannot rotate, the heating amount and the evaporation amount are maximized. As described above, according to the configuration of the present embodiment, by rotating the operation knob 22, the position of the heater 5 can be adjusted, and the transpiration amount can be freely adjusted.

According to the configuration of the present embodiment, the uppermost position of the heater 5 is positioned by the flange portion 10, and the lowermost position is not shown, but the outer container side or the operating knob 22 is appropriately provided with a protrusion or the like. The heater 5 is separated from the inlet 11 by a predetermined distance or more. The position of the heater 5 and the range of its rotation can be set without attaching or detaching any special member, and the structure of the evaporator 1 can be greatly simplified, and the position of the heater 5 and the amount of evaporation can be set. Fine adjustments can be made continuously rather than stepwise.

Next, a second embodiment of the present invention will be described with reference to FIG. The main difference between this embodiment and the above embodiment is that the heater 5 can be moved up and down without rotating. Therefore, the members having the same functions as those in the above-described embodiment are designated by the same reference numerals and the description thereof will be omitted. That is, the outer surface of the heater 5 is formed with three or four guide protrusions 31 in the vertical direction, and these protrusions 31 are formed in the vertical direction inside the small diameter portion 6, or three. Fits in the four guide grooves 32. Therefore, the heater 5 can move up and down along the guide groove 32 without rotating. On the other hand, a screw hole 33 is formed in the flange portion 10, and an operation knob 34 having an adjusting screw formed in a part thereof is screwed into the flange portion 10, and the lower end thereof is rotatably loosely fitted to the upper end of the heater 5. Therefore, by rotating the operation knob 34, the heater 5 can freely move up and down between the position where the heater 5 contacts the flange portion 10 and the position where the heater 5 contacts a positioning means such as a projection (not shown) below.

Also in this embodiment, it is possible to continuously adjust the position of the heater 5 and the evaporation amount without using a special member. Moreover, since the heater 5 does not rotate, the lead wire is not twisted at all, and the safety of the vaporizer 1 is improved.

Next, a third embodiment of the present invention will be described with reference to FIG. The difference between this embodiment and the above embodiment is that the heater 5 can be moved up and down without rotating the operation knob. Therefore, the members having the same functions as those described above are designated by the same reference numerals and the description thereof will be omitted. Inside the small-diameter portion 6, plate members 42 having elastic projections 41 are fixed at appropriate intervals, and a plurality of annular grooves 43 that fit into the projections 41 are formed on the outer surface of the heater 5, for example, a predetermined number. Three lines are formed at intervals. Although the structure in which the plate member 42 is provided is shown here, since the outer container 2 is actually formed of a resin having a certain degree of elasticity, a protrusion that replaces the protrusion 41 without the plate member 42 is provided. The structure in which the container is formed on the inner surface of the container is convenient for manufacturing. On the other hand, an insertion hole 44 is formed in the flange portion 10, and the lower end of the operation knob 45, which is inserted through the insertion hole 44, is fixed to the upper end of the heater 5.

According to the configuration of the present embodiment, by pulling up or pushing down the operation knob 45, any one of the three grooves 43 fits into the protrusion 41, and the heater 5 is arranged in three stages. Can be arranged. Therefore, when the heater 5 is positioned at the uppermost position, when it is positioned at the intermediate position shown by the solid line in FIG. 4, and when it is further positioned at the lowermost position, the heating amount of the liquid absorbent core 12 is different and the transpiration amount varies. Be adjusted. In this way, in this embodiment, since the operation knob 45 is moved up and down on the upper surface side of the container, the movement amount (heating state) of the heater 5 can be easily discriminated from the outside. In addition, it goes without saying that the structure of the present embodiment does not cause the twisting of the lead wire because the heater 5 is not rotated.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The feature of this embodiment is that the heater 5 can be moved up and down by rotating the operation knob. That is, a plurality of guide grooves 32 are vertically formed on the inner surface of the small-diameter portion 6 at predetermined intervals, and guide protrusions 31 are formed on the outer surface of the heater 5 to be fitted to each other. It is configured so that it can move up and down along the guide groove 32. Further, a tooth profile 51 is formed on the outer surface of the single guide protrusion 31, and the operating gear 52 that meshes with the tooth profile 51 of the drug container 2 and is partially exposed to the outside of the drug container 2 is rotatable. Provided. According to this structure, by rotating the operation gear 52 from the outside of the medicine container 2, the heater 5 moves up and down in the small diameter portion 6 to continuously adjust the heating and evaporation of the liquid absorbent core 12. I will get it. In this embodiment, in the operation gear 52, the color of the portion exposed from the outer container 2 is changed by its rotation (for example, when the heating amount is large, the color is red, and the heating amount is small). It is also possible to confirm the heating state of the liquid absorption core by the heater by gradually making the color lighter with this, or making the color gradually different). Although the respective embodiments of the present invention have been described above, it is possible to adjust the vertical position without rattling the heater 5, and thus it is possible to accurately adjust the transpiration amount of the medicine to a desired amount. it can.

It should be noted that the heaters 5 shown in the above-mentioned embodiments are all shown in an annular shape, in other words, a donut shape, and one specific example thereof will be described with reference to FIGS. 6 and 7. FIG. 6 is a plan view of the heater 5, and FIG. 7 is a sectional view taken along the line AA. The heater 5 shown uses a positive thermistor 61 as a heat source, and a lead wire 26 is connected to an electrode 62. Although the electrodes 62 are paired, only one of them is shown for convenience of illustration. The thermistor 61 is held in a case 64 so as to be wrapped with a silicon-based filler 63. An annular radiator 66 is fixed so as to close the opening 65 formed on the inner surface of the case 64. The case 64 is made of, for example, PPS resin, and the radiator 66 can be made of aluminum, stainless, or copper. According to this structure, the radiator 66 is heated by the heat generated from the thermistor 61, and the liquid absorbent core 12 inserted through the hollow portion 23 of the radiator 66 can be efficiently heated from the surroundings.

This configuration is suitable for a configuration in which the heater 5 is moved up and down without rotating as in the second and third embodiments, and the operating knobs 34 and 45 are flange-like fixing portions shown in FIG. It is attached so that it can be operated up and down using 67 and the insertion hole 68. This concrete structure is shown in FIG. In addition, in FIG. 8 of the present embodiment, the same reference numerals are given to the same components as those shown in FIGS. 1 to 7, and the description thereof will be omitted. In the configuration shown in FIG. 8, since the heater 5 has a substantially elliptical shape as shown in FIG. 6, it is not necessary to form a special guide means such as a small diameter portion in the rail shape in the above embodiment. That is, the heater 5 is vertically movably mounted in the heater housing 18 corresponding to the contour of the heater 5. When the heater 5 having this structure is applied to the structure shown in the fourth embodiment, the tooth profile 51 is formed on the outer surface of the case 64 while the operation gear 52 is provided. When the second or third embodiment is applied, the operation knob 34 or 45 is provided corresponding to the case 64 as shown by an imaginary line. In the case where the third embodiment is applied, if the fitted state of the heater 5 is tight, it is possible to obtain a structure that does not require a locking member such as a protrusion. As described above, since the entire heater 5 is not annular, even if the vertical guide groove shown in each embodiment is not particularly formed, the inner wall surface of the container (heater housing By using the portion 18) as a guide means, the heater can be moved up and down without backlash.

[0019]

[Effect of device]

 As described above, according to the heating vaporizer of the present invention, according to the heating vaporizer, the heating element is provided with the guide means for vertically controlling the position of the heating element while horizontally regulating the heating element. Can be moved accurately without displacement. Also, since the one operating means engaged with the heating element has no horizontal positioning function, only the function of moving the heating element. There is no problem with the movement of the. Therefore, for example, the operation means can be easily operated with one hand, and the operation of adjusting the transpiration amount is simplified and the usability thereof is improved. Further, in the present invention, in the configuration in which the operating means moves up and down on the upper side of the outer container, the heating state of the liquid absorption core by the heater can be confirmed by the protruding amount of the operating means. Further, in the case where the operation means is of a rotary type, the heating state of the liquid absorption core by the heater can be confirmed by making the color of the portion exposed from the outer container change due to the rotation.
