[Industrial applications]

 The present invention relates to a floating liquid thermometer, and more particularly, to a floating liquid thermometer that allows users to safely and safely know the liquid temperature of hot water while floating on the liquid surface of a bath or the like.

[0002]

[Prior art]

 In order to know the temperature of liquid such as hot and cold water, a rod-shaped liquid thermometer, which is formed relatively long, is usually used.The bulb part is submerged below the liquid surface, and this is held until a predetermined time elapses. Usually, this is done by reading the liquid temperature through the scale.

However, if attention is paid only to the functional aspect of knowing the liquid temperature, the rod-shaped liquid thermometer can sufficiently achieve the purpose, but the liquid temperature can be maintained for a predetermined time. In addition to the inconvenience of having to measure with, it is also necessary to satisfy the playfulness such as being able to know the amount of hot water while playing while playing with an infant when trying to put it in the bath. However, there was a disadvantage that it did not meet user needs in that it was a practical product that pursued only functionality.

By the way, as a liquid thermometer satisfying the playfulness, for example, like a “liquid thermometer with buoyancy” disclosed in Japanese Utility Model Laid-Open No. 3-6532, it is provided by an airtight chamber formed in the main body. It has already been proposed that buoyancy allows the temperature to be measured while floating on the surface of the liquid, and also allows infants to play with a toy-like sensation without getting bored when taking a bath.

[0005]

[Problems to be solved by the device]

 By the way, even with the liquid thermometer with buoyancy, it is possible to measure the liquid temperature in a bathtub or the like while satisfying the sense of play.

However, since the scale part and the alcohol mercury column part are out of the main body part, the scale part is accidentally dropped on the floor surface or hits another hard member to scratch the scale part. There is a risk of damaging the alcohol mercury column, and improvements have been desired from the viewpoint of durability and safety assurance.

The present invention has been made in view of the above problems of the prior art, and its characteristic feature is that the hot and cold water can be put in and out and can be brought into and out of contact with each other through the opening surfaces that face each other. It is composed of a case body consisting of an upper case part and a lower case part, and a liquid temperature measuring part arranged in this case body part, and a scale display for forming a transparent window part on the surface thereof. The upper case part in which the parts are arranged and the lower case part facing each other are provided on one side so as to define at least one hermetic chamber when they are face-to-face matched with each other. The female cylinder is formed on the other side with the male cylinder facing each other, and the liquid temperature measurement unit is located near the transparent window formed on the upper case to read the temperature from the outside. It is possible to display the scale on the back side, and this scale It is formed of an alcohol mercury column part fixedly arranged in the upper case part so as to be visible through the see-through window part so as to correspond to the display part.

[0008]

[Action]

 For this reason, the case body can be made to float on the liquid surface by the buoyancy provided by the airtight chamber, while constantly letting hot and cold water such as hot and cold water flow in and out to measure the liquid temperature inside. You can stimulate the playfulness of the infant and have it bathed.

Further, of the scale display section and the alcohol mercury column section that constitute the liquid temperature measuring section, the scale display section is positioned near the transparent window formed in the upper case section to read the temperature from the outside. The scale part is displayed on the back side of the mercury column, and the entire arc mercury column is fixedly arranged in the upper case part so that it can be seen through the see-through window. It is possible to effectively prevent the scale portion from being scratched or the alcohol mercury column portion from being damaged, and it is possible to secure the safety of use and improve the durability.

Further, the case main body can be assembled immediately while providing the airtight chamber by integrating the upper case part and the lower case part face-to-face with each other through their respective opening surfaces so as to be integrated. Therefore, the work process in manufacturing can be simplified.

It is formed by arranging the tubular portions 27 and 28 so as to face each other and allowing them to be fitted with each other freely.

To explain this more concretely with reference to the illustrated example, the upper case portion 12 formed by defining the opening surface 14 by the curved peripheral edge portion 13 and exhibiting a substantially boat shape is the top plate portion thereof. By making the height of 15 lower than that of the peripheral portion 13, a plate member 37 made of a plate-shaped transparent resin material or the like having a scale 39 and forming a see-through window 38 is placed on the upper case 12 The top plate portion 15 is formed as flat as possible, and a concave portion 16 for accommodating the alcohol mercury column portion 41 is formed in the central portion in the length direction of the top plate portion 15 as is apparent from FIGS. 4 and 5. Are formed by providing through holes 17 and 18 at the start and end thereof.

Further, as shown in FIG. 4, the female cylinder portions 19 and 20 formed on the upper case portion 12 are disposed so as to be positioned inside by standing on the back surface side of the top plate portion 15 as shown in FIG. Will be done.

On the other hand, similarly to the upper case portion 12, the lower case portion 22 formed by defining the opening surface 24 by the curved peripheral edge portion 23 and having a substantially boat-like shape is as shown in FIG. By arranging the male cylinder portions 27 and 28 on the surface side of the bottom plate portion 25, the male cylinder portions 27 and 28 are positioned and disposed inside thereof.

In this case, the arrangement relationship between the female cylinder portions 19 and 20 and the male cylinder portions 27 and 28 is such that a large-diameter female cylinder is provided on the upper portion of the upper case portion 12 in consideration of balance of buoyancy obtained. A small-diameter female cylinder portion 20 is erected on the lower side of the portion 19, a large-diameter male cylinder portion 27 is provided on the upper side of the lower case portion 22, and a small-diameter male cylinder portion 28 is provided on the lower side. It is desirable that each of them be erected so that they can be freely fitted with each other as shown in FIG. 7. However, the positions and the number of the female cylinder portions 19 and 20 and the male cylinder portions 27 and 28 can be determined. The design matter is not limited to the example shown in the figure, and the essential point is that the airtight chambers 30 and 31 can be formed to give necessary buoyancy to the case body 11. .

As shown in FIG. 3, the bottom plate portion 25 of the lower case portion 22 has a through hole 26 for letting in and out hot water as a small circular hole on the upper side and a through hole 26 on the lower side. They are arranged as three oval holes.
