Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating evaporator, and more particularly to a cordless heating evaporator having a plug blade which is directly inserted into a cosent body of the evaporator.

[0002]

2. Description of the Related Art Conventionally, for example, insecticides, fungicides,
It is widely practiced to vaporize and evaporate miticides, repellents, pharmaceuticals, fragrances, cosmetics, and the like into rooms to obtain the desired effects. The vaporization / evaporation method referred to here includes various methods such as heating a mat-like solid containing a desired chemical or the like, or putting a chemical solution in a container and evaporating as appropriate, but the effect of the evaporation is maintained for a long time. As a suitable method, the liquid to be evaporated is stored in a container, the liquid absorbing core immersed in the liquid is pulled out from the neck of the container, and the liquid absorbing core is heated by a suitable heating means. Vessels are widely used.

In the above-mentioned heating evaporator, as is well known, an electric heater is used as a heating element for heating the liquid absorbing core. The present applicant firstly absorbs the liquid in the liquid container housed in the container of the heating evaporator with the liquid absorbing wick provided in the container, and appropriately uses the electric heater provided in the container to appropriately draw the liquid. Various heating evaporators have been proposed for heating and evaporating.

[0004] As this type of heating and evaporator, there is a cordless type in which a body is provided with a plug blade. This cordless type device is compact in its entirety and can be installed simply by plugging it into an outlet, so that it is easy to use.

[0005]

Among the conventional heat evaporators of this type, those using a solid mat as a material for evaporating not only make the container relatively light because of the heating form of the container,
Since the mat itself was light, there was no problem in terms of structure because of the problem that the heating evaporator could fall out of the outlet. However, in the case of a heating evaporator equipped with a chemical bottle, the weight of the chemical bottle is added in addition to the fact that the body weight becomes relatively heavy due to the heating structure and the bottle holding structure,
Depending on the form, there is a problem that the connection pins of the body are disconnected from the outlet.

Accordingly, if the length of the connecting pin formed below the so-called pin-forming base portion, that is, the wall surface for holding the body in contact with the outlet is greatly extended downward,
Although the holding force can be increased, if the wall is simply increased, inconvenience may occur when packing the evaporator, or, for example, when the evaporator is plugged into the upper plug in a vertical double outlet. However, there were inconveniences such as the inability to use the lower insertion.

On the other hand, in this type of evaporator, various pilot lamps are used so that it is possible to confirm whether or not the switch of the evaporator is turned on.
However, since the pilot lamp is usually provided on the side opposite to the mounting surface of the body and at the bottom of the body away from the transpiration port, if the body is tilted, the pilot lamp becomes difficult to see and the operation status of the evaporator is confirmed There was a problem that it became difficult.
In addition, when the evaporator has been used for a long period of time, there has been a problem that the wall surface to which the evaporator is attached is stained with the evaporating chemical.

SUMMARY OF THE INVENTION The present invention has been made to cope with a so-called set phenomenon in which a body tilts during use. Specifically, a so-called pin forming base on which a connecting pin is formed is provided below a connecting pin. The heating evaporator attached to the outlet can be firmly fixed without increasing the length of the wall in contact with the outlet, or the operation status of the evaporator can be confirmed even if the body is inclined. The aim is to obtain a heated evaporator that can be used.

[0009]

SUMMARY OF THE INVENTION The object of the present invention is to provide:
The liquid in the liquid container accommodated in the container is sucked up by the liquid absorbing core provided in the container, and the liquid absorbing core is heated by the heating element provided in the container to evaporate the liquid. In the heating evaporator provided with a connecting pin protruding from the outside of the body and insertable into an outlet, a length (mm) from a position of the connecting pin to a lower end of a wall of the pin forming base provided with the connecting pin on the outlet side is D. When the weight (kg) of the body body is M and the engaging force between the connection pin and the insertion hole of the outlet is F (kg), D is M / F in the dimensionless number of each value. It can be solved by a heating and evaporator characterized in that the heating evaporator is configured to be in a range of 15 to 60 times the following.

[0010] An object of the present invention is to heat a liquid in a liquid container housed in a container by a heating element provided in the container while sucking the liquid in the container. In the heating evaporator provided with a connecting pin projecting from the outside of the body and capable of being inserted into an outlet, a slit is formed closer to the outlet than the evaporation port on the upper surface side of the body, and the liquid is evaporated. This problem can be solved by a heating and evaporating device characterized in that a light source is provided in the body near the slit and an opening penetrating downward from the light source to the bottle mounting surface is provided.

In the present invention, as described above, the configuration in which the wall surface of the pin forming base extends downward from the projecting position of the connection pin has a characteristic value in consideration of the balance of the entire body, In a state in which the body is attached to the outlet, a moment in the opposite direction that opposes and prevents a moment (dropping force) that inclines the container body downward can be effectively generated. That is, the force generated by the distance between the fulcrum and the force point of the opposite moment based on the engagement force between the outlet and the connection pin can be made desired, and a substantially large holding force is generated with respect to the above-mentioned falling force. The body can be firmly fixed to the outlet, and the body will not fall out even after prolonged use. Thus, a stable and reliable mounting state can be obtained even when the amount of liquid decreases.

Further, as in the present invention, a slit is formed closer to the outlet than the evaporation port on the upper surface side of the container, a light source is provided in the container near the slit, and the light source is directed downward from the light source. Since the opening that penetrates to the bottle mounting surface is formed, the light of the light source can illuminate the wall surface through the slit, so that the light of the light source can be seen from anywhere where the evaporator can be seen It can be confirmed, and the opening and the slit can form a rising airflow different from the evaporation port near the wall.

In the present invention, the shape, size, material, and the like of the body of the heating and evaporator are not limited to the embodiments and are arbitrary. The housing is provided with connection pins that can be directly inserted into an outlet, and the shape of the connection pins may be any shape such as a flat blade or a round pin, and the number of pins is two. , Etc. are arbitrary. In addition, the pin forming base on which the connection pin is formed may be configured such that a rotation axis is provided along the direction of the pin axis, so that it can be appropriately rotated to be adjusted vertically and horizontally at an angle of 90 °.

In the present invention, any heater may be used, such as a heater using a nichrome wire, a semiconductor (positive temperature thermistor), a platinum catalyst, an air oxidation heating material, or the like. The heating temperature is appropriately determined according to the type of the heating evaporant, and is not particularly limited, but is usually about 40 to 150 ° C, preferably 60 to 150 ° C.
The heating element surface temperature is in the range of 145 ° C, and at this time, the liquid absorbent core surface temperature is 30 to 135 ° C, preferably about 40 to 130 ° C.
Is set to be In the present invention, the liquid-absorbing core may be any of various materials generally used, for example, felt, cotton, pulp, non-woven fabric, asbestos, inorganic moldings, etc., and may be a felt core (including a resin sintered core), a sintered core. , Pulp cores and inorganic molded cores are preferred.

[0015] In the present invention, the heat-evaporating agent to be put into the chemical bottle may be any of insecticides, fungicides, acaricides, repellents, fragrances, deodorants, fungicides, and socidals. In the present invention, the engaging force F between the hole of the outlet and the connection pin F
For example, the pulling force required when the body is pulled out from the outlet is, for example, the dimensionless number of each of the values, the D is in the range of 15 to 60 times the M / F.

This setting method is set based on the shortest distance Y from the center of gravity of the body to the plane including the outer surface of the outlet to be connected, and the distance D from the center point between the plurality of connection pins to the bottom of the pin forming base. be able to. If the specified range is deviated from the specific range set by the setting requirements, a set of the body attached to the outlet occurs, and a trouble such as a plug of the body falling off from the outlet occurs. The Electrical Appliance and Material Control Law of Japan specifies the engaging force F between the socket hole and the connection pin. For example, when the rated current is 15 amps or less and 2 poles, the standard is 0.5 kg or more and 6.0 kg or less. In addition, overseas, for example, in the Australian standard, 0.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on embodiments, but the present invention is not limited to these embodiments. FIG. 1 is a longitudinal sectional view of a heat evaporator according to a first embodiment of the present invention, and FIG. 2 is a longitudinal sectional view of FIG. 1 with a chemical bottle attached.

The container 3 of the heating evaporator 1 shown in FIG. 1 has a squirt opening 4 at the top of the container, a bottle mounting port 7 and an air intake 15 at the bottom 2 of the container. Has a connection pin 12 on the left and a switch 14 on the right. A ring heater 5 is provided in the body 3 through a support column 6.
And 13 is a lead-out terminal of the ring heater 5. A screw portion 10 is formed in the bottle mounting opening 7, and a screw portion 9 of a neck portion of the chemical liquid bottle 8 is screwed to the screw portion 10, and the chemical liquid bottle 8 is set on the body 3. Reference numeral 11 denotes a liquid absorbing core, the tip of which is a ring heater 5.
It is configured so as to reach the circular hole.

The symbols Y, D, F, and M in FIG.
Is a basic parameter for indicating the force relationship acting when the is mounted on an outlet provided on a vertical wall. Y is the shortest distance from the center of gravity of the container 3 to a plane including the outer surface of the outlet connected thereto. D is the distance from the center point between the connection pins 12 to the lower end portion A of the pin forming base 20. F corresponds to an engaging force between the connection pin 12 and the insertion hole of the outlet, in other words, a pulling force when the connection pin 12 is pulled out. The force that pulls the body 3 down is
Actually, the weight becomes uncertain when the liquid medicine bottle 8 is mounted. However, in the present invention, the weight of the container 3 can be replaced with M as the weight. In the present invention, even when the value of M, which is the weight of the body, is used as a parameter, a sufficient result for grasping the usage state of the body could be obtained. Here, the above-mentioned F has a certain range in the standard and cannot be made larger than a certain value. It is desirable that the body weight M is small, but there is always a limit. That is, it is extremely difficult to reduce the size and weight of the body weight M in view of the strength and safety of the body.

As for the position (Y) of the center of gravity, there is an element that is actually related to the shape of the vessel 3. That is,
If the transpiration hole 4 gets too close to the wall surface on which the outlet is located, the wall surface will be soiled, and as shown in FIG.
Has a so-called gap 30 that is narrower than the other parts of the vessel. It is necessary to make it easy to form an ascending air flow separate from the transpiration air flow near the wall. Thus, it was difficult to reduce the value of Y. D
Is too large, the packaging box becomes distorted at the time of packing, and all elements have difficulty.

In this embodiment, the pin forming base 2
The pin forming base 20 was configured such that D on the wall surface of 0 (wall surface in contact with the outer surface of the outlet) was 15 to 60 times the M / F. In a state in which the heating evaporator configured as described above is mounted on an outlet provided on a substantially vertical wall, a moment (Y ×
M), the ratio of the magnitude of the moment (D × F) in the opposite direction can be increased. That is, it is possible to generate a substantially large holding force with respect to the above-mentioned falling force without increasing the distance between the fulcrum A and the power point of the opposite moment based on the engaging force between the outlet and the connection pin 12. The container can be firmly fixed to the outlet even when the liquid is sufficiently contained in the bottle, as well as when the liquid medicine is reduced by use.

Although not essential in the present invention, legs may be provided on the pin forming base as required, as shown in FIGS. FIG. 4 is a longitudinal sectional view showing another embodiment of the present invention. In this case, the elastic pieces 13 provided on the left and right sides of the bottle mounting opening 7 are provided in place of the screw portions 10 of the above-described embodiment, and the projections 21 are formed on the lower ends of the leg portions 22 of the pin forming base 20. Are formed. In the present embodiment, the configuration is substantially the same as that in FIGS. 1 to 3 except for the configuration in which the elastic piece 13 engages with the screw portion of the chemical liquid bottle 8 and the configuration of the protrusion 21.

By providing the projections 21, for example, when the outlet slightly protrudes from the other wall surface as shown in the drawing, the projections 21 appropriately contact the wall surface below the outlet 25. Therefore, the container 1 can be effectively supported. The amount of protrusion of the projection 21 is not particularly limited, but when the outlet 25 projects as shown in FIG.
Of course does not adversely affect the supporting state of the device.

The present invention can be configured as shown in FIG. In FIG. 5, portions other than D of the pin forming base 20, which is one of the elements of the present embodiment, are omitted for convenience.
In FIG. 5, the upper outlet 2 protrudes from the outside of the body.
The pin forming base 20 in which the connecting pin 12 insertable into 5a is formed has a leg portion 22 in which the supporting wall surface in contact with the outer surface of the outlet extends in a region across the insertion hole of the lower outlet 25b arranged vertically. I have. The lower portion of the leg portion 22 is provided with a notch 23 so that the insertion hole of the outlet 25b can be exposed, and even when the heating evaporator is inserted into the outlet 25a, as shown by a virtual line X in the figure. The notch 23 corresponds to the outlet 25b, so that the lower outlet 25b can be used.

In each of the above-described embodiments, the leg formed by extending the pin-forming base downward can be formed integrally with the pin-forming base. In each embodiment, the leg is attached to and detached from the pin-forming base. It is freely configured. In addition, the structure which makes this leg part detachable to the pin formation base, for example, the structure which tightens this base part or screws a part of leg part,
Alternatively, various structures such as a structure in which the leg is directly screwed into the base can be adopted.

Since the legs are configured to be detachable in this manner, it is convenient because the legs are not obstructed when packing the evaporator. Although not shown, a bendable joint may be provided on the leg to store the leg except during use, such as during packaging. Further, the present invention can naturally adopt a configuration in which the above embodiments are appropriately combined.

Another embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a plan view of the heating evaporator, and FIG. 7 is a sectional view taken along line AA of FIG. In FIGS. 6 and 7, the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted. The heating evaporator 40 shown in both figures has a slit 41 formed on the upper surface side of the body 3 at a position closer to the outlet 25 than the evaporation port 4 (position on the wall surface 50 side). A light source 42 is provided near the slit 41 and in the housing 3. Further, the opening 4 extends downward from the light source 42.
3 are formed. The opening 43 is configured to penetrate to the mounting surface of the chemical liquid bottle 8. Also, the opening 43
A plurality of ventilation holes 45 are formed at a position closer to the liquid absorption core in order to effectively evaporate. The heating evaporator 40 shown here has a mounting base (pin forming base) of the connection pin 12 that is rotatable, as shown in FIG. 2 of Japanese Utility Model Application Laid-Open No. 1-130674, for example. The degree of freedom of the mounting form can be increased.

The vessel 3 constructed as described above includes a light source 42
Can illuminate the wall surface through the slit 41. Further, the rising airflow formed by the opening 43 and the slit 41 forms another rising airflow near the wall, which is different from the evaporation airflow formed between the transpiration port 4 and the ventilation port 45, and the chemical liquid adheres to the wall surface 50. Can be avoided. Further, by determining the positions of the light source 42 and the opening 43 so as to simultaneously irradiate the wall surface 50 and the bottle piece, not only the wall irradiation effect but also a bottle irradiation effect that makes it easy to confirm the residual liquid in the bottle even in a dark place. Can be obtained.

[0029]

As described above, according to the present invention, since the interval D on the wall surface of the pin forming base is 15 to 60 times the M / F, the pin forming base has a lower side than the connection pin. Even if the size (spacing D) of the portion extending to is not so large, in the state where the heating evaporator is inserted into the outlet, the evaporator is opposed to the falling force that tends to incline the evaporator body downward and is prevented. It is possible to increase the proportion of the opposite moment to be attempted, to generate a substantially large holding force against the magnitude of this falling force, and to fix the body firmly to the outlet it can. Therefore, a state in which the heating evaporator is attached to the outlet, that is, a stable and reliable attachment state without causing the body to fall off even after long-term use can be obtained. In addition, since the interval D is not configured to be unnecessarily large but configured to be an optimal size,
For example, the use of an outlet having a plurality of outlets does not limit the use of other outlets. As described above, according to the present invention, a safe and easy-to-use heating evaporator can be provided.

Further, according to the present invention, a slit is formed closer to the outlet than the evaporation port on the upper surface side of the container, a light source is provided in the container near the slit, and the light source is directed downward from the light source. Since the opening that penetrates to the bottle mounting surface is formed, the light of the light source can illuminate the wall surface through the slit, so that the light of the light source can be seen from anywhere where the evaporator can be seen Since the opening and slit can form an ascending airflow separate from the transpiration airflow by the transpiration port, it is possible to effectively prevent contamination of the wall surface by the chemical solution even when used for a long time. A heat evaporator can also be provided.
