Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a thermometer, and more specifically, to a thermometer body in which a temperature-sensing part having a diameter smaller than that of the main body extends integrally from a body part provided with a display part; The present invention relates to a thermometer equipped with a protective cover that encloses a heating section.

[Background Art] A thermometer body generally includes a body portion including a display portion and a temperature-sensing portion having a smaller diameter than the body portion;
In a thermometer equipped with a protective cover that encloses a temperature-sensing part, the temperature-sensing part extends from approximately the center of the distal end surface of the thermometer body, and positioning means is also provided inside the protective cover. Because the protective cover is attached to the temperature-sensing part, the main body and the protective cover are not positioned properly, and the temperature-sensing part rattles inside the protective cover, causing it to hit the inner circumferential surface of the protective cover. The small diameter temperature sensing part may be damaged.

[Purpose of the invention] The present invention has been made in view of the above points, and its main purpose is to guide the protective cover when covering the temperature sensing part with the protective cover. The purpose is to prevent damage to the temperature sensing part by preventing the heating part from rattling within the protective cover.

[Disclosure of the invention] In the present invention, a main body portion having a display portion,
One side is substantially flush with one side of the main body, and the other side opposite to this one side is formed to be thinner than the main body, and has a smaller diameter than the main body. The thermometer body is composed of a temperature sensing part that extends integrally into the main body part and a protrusion formed on the outer surface of the tip of the body part on the temperature sensing part side, and a protective cover that covers the temperature sensing part can be attached and removed from the thermometer body. By forming a retaining rib on the inner circumferential surface of the protective cover to hold the tip of the temperature-sensing section, the temperature-sensing section can be mounted with the side surface of the temperature-sensing section in contact with the inner circumferential surface of the protective cover. To disclose a thermometer in which a protective cover is placed over a portion of the thermometer, and the tip of the temperature sensing portion is held by a holding rib to prevent the temperature sensing portion from wobbling within the protective cover.

(Example 1) The thermometer main body 1 incorporates an electronic circuit to which a temperature sensing element such as a thermistor is connected, and is formed into an elongated rectangular parallelepiped shape as shown in FIGS. 1 and 2. A temperature-sensing section 3 having a built-in temperature-sensing element 4 is formed integrally extending from one end surface in the longitudinal direction of the section 2 to its tip. The main body section 2 is provided with a display section 11 such as a liquid crystal display and a power switch 12. The temperature sensing portion 3 is formed to have a smaller diameter than the main body portion 1 so as to reduce the heat capacity around the temperature sensing element 4 built into the tip and improve responsiveness. One side of the temperature sensing section 3 in the width direction is formed to be substantially flush with one side of the main body 1 in the width direction, and therefore, in the width direction, the center line of the main body 1 and the temperature sensor The shape is such that the center line of the portion 3 is shifted from the center line of the portion 3. In addition, in the thickness direction, as shown in FIG. 2, the temperature sensing portion 3 is formed in a tapered shape that tapers rapidly toward the tip.

When not in use, the temperature sensing section 3 is fitted with a protective cover 5, and the protective cover 5 is formed in the shape of an elongated cylinder with a bottom and one end surface in the longitudinal direction is open. As shown in FIG. 3, a plurality of holding ribs 21 are protruded from each inner peripheral surface of the protective cover 5.
The holding rib 21 protrudes from a portion of the protective cover 5 near the closed end so as to leave a space approximately equal to the diameter of the temperature sensing portion 3 of the thermometer body 1. Therefore, when the protective cover 5 is attached to the temperature sensing section 3, the retaining rib 21
This prevents the temperature sensing portion 3 from shaking inside the protective cover 5 due to the abutment of the tip end of the temperature sensing portion 3. The locking rib 21 is curved so that the inner diameter of the protective cover 5 gradually increases as the portion near the open end approaches the open end side to form a guide portion 22, which guides the temperature sensing portion 3 inside the protective cover 5. When the thermosensing section 3 is introduced into the guide section 22, the distal end of the thermosensing section 3 comes into sliding contact with the guide section 22, so that the thermosensing section 3 is smoothly introduced into a predetermined position. An engagement recess 23 is formed in the inner peripheral surface of the open end of the protective cover 5, that is, the main body 2
As shown in FIG. 4, a protrusion 24 that can be fitted into the engagement recess 23 is provided on the back side of the display section 11 provided at the tip end on the side of the temperature sensing section 3 .

However, when attaching the protective cover 5 to the temperature sensing section 3, one side of the body section 2 in the width direction and the temperature sensing section 3 must be
Since one side in the width direction of It can be mounted without colliding with the inner circumferential surface of the thermosensing section 3, and damage to the temperature sensing section 3 can be prevented. Further, since the holding ribs 21 are provided protrudingly on the inner circumferential surface of the protective cover 5, the tip of the temperature sensing section 3 is housed in the space between the holding ribs 21 without wobbling, and is engaged. By fitting the recess 23 and the projection 24, the thermometer main body 1 and the protective cover 5 are combined. Further, the length of the protective cover 5 is set so that the display section 11 is exposed when the protective cover 5 is attached to the thermometer body 1,
The exhibition effect is enhanced.

By the way, as mentioned above, the thermometer body 1 is provided with a protrusion 24 for connecting the protective cover 5, and since the body part 2 is heavier than the temperature sensing part 3, the center of gravity of the thermometer body 1 is is located on the main body 2 side with respect to the protrusion 24, and the protective cover 5
When placing the thermometer body 1 on a tabletop or floor with the thermometer body 1 removed, if this protrusion 24 is placed downward, the thermosensing part 3 is formed into a tapered shape as shown in FIG. As such, the temperature sensing portion 3 is raised from the mounting surface 6. That is, the temperature sensing section 3 does not collide with the mounting surface 6, and damage to the temperature sensing section 3 is prevented. The protrusion 24 may also be provided on the display section 11 side as shown by the broken line in FIG.
In this case, the thermometer main body 1 can be placed in a state where the temperature sensing part 3 and the display part 11 are raised from the placement surface 6 whether the display part 11 is placed upward or downward. .

(Embodiment 2) This embodiment discloses an example in which the holding rib 21 formed inside the protective cover 5 is constituted by an elastic piece 25 on the open end side of the holding cover 5. 6th
As shown in the figure, the holding rib 21 is formed inside the protective cover 5 along the longitudinal direction, and roughly divides the inside of the protective cover 5 into two in the width direction. One end of the holding rib 21 on the open end side of the protective cover 5 has elasticity, and as shown in FIG.
It is an elastic piece 25 spaced apart from the inner peripheral surface of the protective cover 5, and is flexible in the width direction of the protective cover 5. A fitting part 26 whose thickness increases in the width direction of the protective cover 5 is formed at the free end of the elastic piece 25, and a fitting part 26 is formed on the inner peripheral surface of the protective cover 5 at a position corresponding to this fitting part 26. A fitting recess 27 is formed. Therefore, after molding the protective cover 5, if the elastic piece 25 is bent to fit the fitting part 26 into the fitting recess 27 as shown by the imaginary line in FIG. Similarly, a guide portion 22 is formed at one end of the holding rib 21 on the open end side of the protective cover 5 to protect the temperature sensing portion 3. This controls the position when inserted into the cover 5. Further, since the guide portion 22 has elasticity, the risk of damaging the temperature sensing portion 3 when the temperature sensing portion 3 comes into contact with the guide portion 22 is further reduced.

(Embodiment 3) This embodiment discloses an example in which a large number of needle-shaped elastic protrusions 28 are protruded from the inner peripheral surface of the closed end of the protective cover 5. As shown in Figure 8,
A retaining rib 21 is provided on the inner peripheral surface of the closed end of the protective cover 5.
A large number of elastic protrusions 28 are integrally protruded at positions corresponding to the spaces surrounded by. Therefore, the temperature sensing part 3
When inserted, the temperature sensing element 4 will face this elastic protrusion 28, and when the temperature sensing element 4 is dropped, the elastic projection 28 will come into contact with the temperature sensing element 4 to reduce the impact of the fall, and the temperature sensing element 3 damage can be prevented.

[Effect of the invention] As described above, the present invention has a main body having a display section, one side of which is approximately flush with one side of the main body, and the other side opposite to this one side sharply. A temperature-sensing section that is formed to be thinner and have a smaller diameter than the main body, and extends integrally with the main body at an angle to the main body, and a temperature-sensing section formed on the outer surface of the tip of the main body on the temperature-sensing section side. The thermometer body is formed by the protrusions, and a protective cover surrounding the temperature-sensing part is detachably attached to the thermometer body, and a retaining rib for holding the tip of the temperature-sensing part is formed on the inner peripheral surface of the protective cover. Since one side of the thermometer's temperature-sensing part and one side of the main body are approximately flush with each other, when placing the protective cover over the temperature-sensing part, the inner circumferential surface of the protective cover can be rubbed against that side. When the temperature sensing part is brought into contact with the inner circumferential surface of the protective cover, the temperature sensing part is guided into the protective cover with its position regulated, and the temperature sensing part does not wobble inside the protective cover. This has the advantage of preventing damage caused by collision. Moreover, one side is substantially flush with one side of the main body, and the other side opposite to this one side is formed to be thinner than the main body, and has a smaller diameter than the main body. Since the temperature-sensing section is integrally installed on the main body, it is easier to wear the temperature-sensing section by placing it on the area to be measured, such as the armpit, while keeping one side of the temperature-sensing section along the skin. Moreover, it has the advantage that the display section of the main body can be made large for easy viewing.

Furthermore, the protrusion formed on the outer surface of the tip of the main body on the temperature-sensing part side serves as an engaging protrusion for the protective cover, which makes it possible to ensure the connection between the thermometer body and the protective cover, and also makes it possible to remove the protective cover. If you place the thermometer body on a tabletop or floor with the protrusion facing down, the temperature-sensing part is formed in a tapered shape, and the temperature-sensing part will rise above the surface on which it is placed. It has the advantage that the temperature sensing part can be protected as a shape, and the protrusion can be used as a finger rest when attaching and removing the temperature sensing part to the site to be measured. In addition, in the case where the retaining rib is formed in a curved shape to gradually widen the diameter inside the protective cover on the base side of the temperature sensing part, the temperature sensing part will curve when the temperature sensing part is inserted into the protective cover. The location is regulated by the department,
It can be smoothly introduced into a predetermined position, and has the advantage that the protective cover can be easily attached.
