  The present invention relates to a technology of a heat evaporation device that evaporates an evaporation agent filled in a bottle by heating.

  2. Description of the Related Art There is known a heat evaporation apparatus for dispersing insecticides or fragrances for exterminating pests such as mosquitoes filled in a liquid container (for example, a bottle) or a fragrance into a room. In such a heat evaporation apparatus, for example, there is an apparatus configured such that a bottle filled with a chemical solution or the like can be arbitrarily attached and detached. Further, there is known a heat evaporation device that applies heat to a liquid absorbent core provided to protrude from a bottle to evaporate a drug solution or the like filled in the bottle.

The mounting of a bottle in a conventional general heating and evaporating apparatus is performed by press-fitting the bottle into the apparatus, that is, by pressing the bottle to a predetermined position with a strong force. Also, when removing the bottle from the apparatus, it is necessary to insert a finger or the like into the inside of the apparatus and insert the finger or the like into the "gap" between the bottle and the apparatus to pull out the bottle with a strong force. Therefore, there are cases where the bottle cannot be easily removed from the device.
Also, when installing, push the bottle into the device with strong force. For this reason, the position of the liquid absorbent core is not determined, and the liquid absorbent core is brought into contact with the inner surface of the apparatus before reaching the heating unit, and the liquid absorbent core may be damaged.

  In order to solve such a problem, in the mosquito trap disclosed in Patent Document 1, the rib of the container is engaged with a plurality of locking claws relatively separated with the movement of the push button when the push button is pressed. The structure to stop is adopted. Therefore, it is described that the container is securely mounted, and the mounted container can be easily removed.

[Example of Embodiment]
FIG. 1 is a diagram illustrating an example of the configuration of the heating and evaporating apparatus according to the present embodiment. FIG. 1 shows a state in which the bottle 300 is mounted on the heating and evaporating apparatus 10, (a) is a schematic longitudinal sectional view, (b) is a bottom view, and (c) is a sectional view of FIG. FIG. 3 is a schematic vertical sectional view when viewed from a direction orthogonal to the direction.
The heating and evaporating apparatus 10 has a casing 100 formed in a substantially dome shape having, for example, a hemispherical portion at an upper portion thereof. The heat evaporation device 10 is configured so that a bottle 300 filled with a liquid can be mounted in the internal space of the housing 100. Details will be described later.
The bottle 300 is a liquid container that is filled with a chemical solution and is provided to protrude from the inside of the container to the outside of the container, and has a liquid absorbing core 301 immersed in the chemical solution in the container. It is sucked up from the bottle body via 301. The liquid medicine sucked up by the liquid absorbing core 301 is evaporated by heating the liquid absorbing core 301 by a heating unit 103 described later. Further, as shown in FIG. 1 (c), one or two remaining amount checking windows 207 are formed in the heating and evaporating device 10 so that the remaining amount of the chemical solution can be checked without removing the bottle 300 from the device. ing.

  The housing 100 of the heat evaporation device 10 is provided with a hole 101 (sometimes referred to as a drug evaporation window) for discharging the heat-evaporated chemical solution to the outside of the housing. The heating and evaporating apparatus 10 is also provided in an internal space of the housing 100 and accommodates the bottle 300 in the internal space together with a holder 200 to be described later (hereinafter, referred to as a container) 102. A heating unit 103 is provided at an upper portion of the heating unit 102.

  The heat evaporation device 10 is electrically connected to a power supply (not shown) via a power cord 400. The heating and evaporating apparatus 10 also constitutes a part of the housing 100 and starts (ON) or stops power supply to the heating unit 103 via the switch 104 provided in the housing 100 ( OFF). Thereby, the user of the heating and evaporating apparatus 10 can perform an ON / OFF operation of the apparatus from outside the housing 100. The user can activate the device by pressing the switch 104 once, or can stop the device by pressing the switch 104 again.

  The holder 200 has a fitting hole 201 (see FIG. 3) configured to be able to engage with a predetermined portion of the bottle 300. As shown in FIG. 1A, one or a plurality of grooves (fitting grooves) are formed in a predetermined range of the outer periphery of the bottle body with reference to a point where the liquid absorption core 301 and the bottle body are connected in the bottle 300. Can be formed so that the fitting hole 201 engages with the fitting groove.

The holder 200 (also referred to as a bottle receiver) that holds the bottle 300 is housed in the inner space of the housing 102. The container 102 has a mechanism for sliding the holder 200, and the holder 200 moves up or down relative to the container 102 in the internal space of the container 102 (see FIG. 1A). (Arrow direction). The mechanism for sliding the holder 200 in this manner functions as a proximity / separation unit that causes the liquid absorption core 301 of the bottle 300 to approach or separate the heating unit 103.
Further, the bottle 300 is mounted on the heating and evaporating apparatus 10 via the container 102 and the holder 200. That is, the container 102 and the holder 200 function as a mechanism for mounting the bottle 300 at a predetermined position of the heating and evaporating apparatus 10.

On the inner surface of the container 102, a guide 202 is formed which is in contact with one portion of the outer peripheral surface of the bottle 300 held by the holder 200. The guides 202 are disposed at three or four places at equal intervals so as to cover the periphery of the holder 200, and the center of the guide 202 matches the center of the heating unit and the housing. Therefore, the holder 200 can be moved up or down relative to the container 102 without any displacement from the center of the heating unit 103.
In addition, the guide 202 makes it easier to bring the liquid absorbing core 301 of the bottle 300 and the heating unit 103 closer together with a predetermined gap. Details will be described later.

  In the heating and evaporating apparatus 10 according to the present embodiment, guides 202 are formed at four locations on the inner surface of the container 102. Since the outer peripheral surface of the holder 200 is in contact with the guide 202, the center of the holder 200 coincides with the centers of the heating unit and the container. A pressing portion 203 is formed on the inner surface of the holder 200 to press the outer peripheral surface of the bottle from the outer peripheral side so that the bottle 300 does not drop unexpectedly. The magnitude of the pressing force applied to the bottle 300 by the pressing unit 203 is set to a size that can prevent the bottle from falling freely. The pressing portion 203 is formed by, for example, forming a rubber member capable of preventing the bottle from slipping into a ring shape. As described above, the mechanism for sliding the holder 200 includes the guide 202 and the pressing portion 203.

  Further, as shown in FIG. 1A, the container 102 and the holder 200 are connected via a first spring material 205. The first spring member 205 is, for example, a coil spring, and moves the holder 200 in a direction away from the upper bottom surface of the container 102, that is, in a relatively downward direction, based on the upper bottom surface of the container 102. Applying a strong pressing force.

  Further, the heat evaporation device 10 includes a bottle stopper 250 and a second spring member 251 that presses the bottle stopper 250 in the horizontal direction. The bottle stopper 250 is a ring formed in a substantially annular shape and configured to be slidable in the horizontal direction with respect to the heating and evaporating apparatus 10. As shown in FIG. 1B, the bottle stopper 250 includes a contact portion 250a and an operation portion 250b that extend from the hole of the ring toward the center thereof and that contact the bottom surface of the bottle 300 when mounted. Have. The operation section 250b is used to operate the contact section 250a to contact the bottom of the bottle or to separate from the bottom of the bottle, and is formed to protrude outside the housing 100. The bottle stopper 250 is provided so as to be slidable by the base 206 and the container 102.

When the container 102 accommodates the bottle 300 held by the holder 200, the bottle stopper 250 causes the contact portion 250a to abut on the bottom surface of the bottle. Maintain the proximity state of. As described above, the bottle stopper 250 functions as a holding unit that holds the bottle 300 in a state where the heat generating unit of the heating unit 103 and the liquid absorbing core 301 are close to each other.
In the bottle stopper 250 according to the present embodiment, the state shown in FIG. 1B is the normal state due to the pressing force from the second spring member 251 regardless of whether the bottle 300 is mounted. I do.

FIG. 2 is an enlarged view of the heating unit 103.
The heating unit 103 is electrically connected to a power supply via a switch 104, and is configured so that the heat generation unit starts generating heat when power supply is started. The heat generating portion is formed in a ring shape having a predetermined height, for example, and the liquid absorbing core 301 of the bottle 300 is inserted from the direction of arrow A shown in FIG. That is, the heat generating portion is formed in a size that allows the liquid absorption core 301 to be inserted into and removed from the internal space. Specifically, the heat generating portion is formed in such a shape and size that a predetermined gap is left between the inner surface of the heat generating portion and the outer surface of the liquid absorbent core 301 in a state where the liquid absorbing core 301 is inserted. You. The size of the gap can be arbitrarily set in advance based on the type of the chemical solution, the temperature at the time of energization of the heat generating portion, the set value of the amount of evaporation per unit time, and the like.

  Thus, the heating unit 103 functions as a heating unit for heating the liquid absorbent core 301 and evaporating the liquid from the liquid absorbent core. In addition, even when the bottle 300 is repeatedly inserted and extracted, the action of the above-described mechanism for sliding the holder 200 can prevent a variation in the interval between the heating unit 103 and the liquid absorbing core 301.

FIG. 3 is a perspective view illustrating the relationship between the holder 200 and the bottle 300.
The holder 200 is formed using, for example, a resin material. As shown in FIG. 3, the holder 200 includes an arm 210 connected to the container 102 and a groove 211 for accommodating the first spring member 205, a stopper portion 212 for regulating a rising position of the bottle, and a bottle (liquid absorbing core). It is configured to include a fitting hole 201 for determining a position.

  The arm 210 is inserted into a hole formed in the upper part of the container 102, and has a hook-shaped restricting portion formed at the tip, thereby restricting the arm 210 from falling out of the container 102. I have.

Further, the holder 200 can move a distance L (FIG. 1A) between the hook on the arm 201 and the upper surface of the container 102 in the internal space of the container 102. The amount of the bottle 300 projecting from the bottom of the apparatus is determined by the distance L. In addition, it is necessary to adjust the distance L so that the bottle can be grasped.
The holder 200 can be pushed in until the stopper portion 212 comes into contact with the upper part of the container 102, and the bottle 300 can be pushed out of the apparatus by the repulsive force of the first spring material 205 at this time.

FIGS. 4A and 4B are views for explaining a state in which the bottle 300 is mounted on the heating and evaporating apparatus 10, in which FIG. 4A is a schematic longitudinal sectional view, and FIG. 4B is a bottom view.
When mounting the bottle 300 on the heating and evaporating apparatus 10, the bottle 300 is pushed toward the cavity on the bottom of the apparatus. At this time, the bottle stopper 250 slides in the horizontal direction in the process of pushing the bottle 300 into the hollow portion, so that the bottle can be inserted into the heating and evaporating apparatus 10.

When the bottle 300 is pushed into the internal space of the container 102 by a predetermined amount, the bottle 300 is connected to the holder 200, that is, the fitting hole 201 is engaged with the fitting groove of the bottle 300 (FIG. 4A). . Subsequently, the bottle 300 is pushed into the rising stop position of the holder 200. Until the holder 200 reaches the lifting stop position, the contact portion 250a of the bottle stopper 250 is in contact with the outer surface of the bottle 300. In other words, the contact portion 250a moves outward from the outer periphery of the bottom of the bottle in accordance with the insertion of the bottle 300 into the hole.
When the bottle 300 is pushed down to the position where the holder 200 stops moving upward, the state of the contact portion 250a transitions from contact with the outer surface of the bottle 300 to contact with the bottom surface of the bottle. Thereby, the mounting of the bottle 300 is completed, and the proximity state between the heat generating part of the heating part 103 and the liquid absorbing core 301 is maintained. In this state, power supply to the heating unit 103 is started, and evaporation of the chemical starts.

FIG. 5 is a diagram for explaining a state when the bottle 300 is removed from the heating and evaporating apparatus 10.
When removing the bottle 300 from the heating and evaporating apparatus 10, after stopping the power supply to the heating unit 103, the operation unit 250b of the bottle stopper 250 is pushed in the direction of the arrow shown in FIG. As a result, the contact portion 250a of the bottle stopper 250 is detached from the bottom of the bottle, and as shown in FIG. 5, the holder 200 is lowered by the repulsive force of the first spring material 205, and a part of the bottle 300 is heated and evaporated. 10 is projected outward. As described above, when the first stopper 205 releases the contact of the bottle stopper 250 with the bottom surface of the bottle, the first spring member 205 relatively separates the holder 102 from the holder 200 and moves the bottle 300 to the It has the function of discharging to the outside.
When the bottle 300 is removed from the heating and evaporating apparatus 10, the hook of the arm 210 restricts the holder 200 from falling out of the container 102. Therefore, a state in which a part of the bottle 300 projects outside the heating and evaporating apparatus 10 is maintained.
In addition, since the holder 200 holding the bottle 300 is relatively separated in a predetermined direction (downward direction) via a mechanism for sliding the holder 200, suction is performed even when the bottle 300 is removed from the heat evaporation device 10. The contact between the liquid core 301 and the heating unit 103 and the inner surface of the container 102 can be avoided.

As described above, in the heating and evaporating apparatus 10 according to the present embodiment, the bottle 300 can be easily attached to and detached from the apparatus, and an unexpected drop of the bottle 300 can be prevented.
When the bottle 300 is mounted on the heat evaporation device 10, the bottle 300 held by the holder 200 can be smoothly moved to a predetermined position via a mechanism for sliding the holder 200. Therefore, the occurrence of breakage of the liquid absorbent core 301, the heating unit 103, and the like is suppressed.

  Further, when removing the bottle 300 from the heating and evaporating apparatus 10, a part of the bottle 300 protrudes out of the heating and evaporating apparatus 10 simply by pushing the operation section 250 b of the bottle stopper 250 toward the apparatus side. Therefore, the bottle 300 can be easily removed, and there is no need to provide a “gap” for inserting a finger or the like when removing the bottle, so that the size of the apparatus can be further reduced.

  Furthermore, since a state in which a part of the bottle 300 protrudes outward from the heating and evaporating apparatus 10 is maintained, an unexpected drop when the bottle 300 is removed from the heating and evaporating apparatus 10 can be suppressed. Therefore, it is possible to prevent the bottle from being damaged due to a drop impact or the like.

  The embodiments described above are for describing the present invention more specifically, and the scope of the present invention is not limited to these examples.
