Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example (b): referring to fig. 1-3, a temperature sensing device for a milk warming device comprises a connecting plug 31 and a temperature sensor 32 coaxially arranged with the connecting plug 31, wherein a groove 311 is arranged at the end of the connecting plug 31, the temperature sensor 32 is positioned in the groove 311, a conducting wire is connected to the temperature sensor 32, and the conducting wire extends out of the connecting plug 31. When the baby bottle 4 is inserted into the heating seat 21, the side wall of the baby bottle 4 closes the end of the connecting plug 31, so that the recess 311 becomes a closed space. In the conventional detection technology, the temperature sensor 32 is directly contacted with the feeding bottle 4, but because the temperature of the side wall of the heating seat 21 is far higher than the temperature of the surface of the feeding bottle 4 and the temperature sensor 32 is very close to the heating seat 21, the heating seat 21 has a great influence on the temperature sensor 32, so that the temperature sensor 32 cannot accurately measure the temperature of the feeding bottle 4.

The present embodiment directly detects the ambient temperature in the recess 311, and this temperature is the temperature of the bottle body and the heat radiation of the milk, and is close to the temperature of the milk, so as to avoid the influence of the heating seat 21 on the temperature sensor 32, and ensure the accuracy of the detection.

Referring to fig. 1-4, the connecting plug 31 is made of rubber, so that the rubber plug can deform to make the rubber plug elastically contact with the sidewall of the feeding bottle 4, thereby improving the sealing performance between the connecting plug 31 and the feeding bottle 4 and further facilitating the accuracy of temperature detection. Or wooden plug and heat insulating cotton. The temperature sensor 32 is embodied as a temperature sensitive electronic package.

Referring to fig. 1 to 4, the temperature sensor 32 is interference-fitted with the connection plug 31 such that the temperature sensor 32 cannot slide in the connection plug 31 without an external force.

Referring to fig. 1-4, the shape of the recess 311 may be a regular sphere, a polygonal prism, or a cylinder, as long as a sealing engagement between the connecting plug 31 and the sidewall of the nursing bottle 4 is ensured.

Referring to fig. 1 to 4, a through hole is formed in a side wall of the heating base 21, the connecting plug 31 is inserted into the through hole in an interference manner, the positioning ring 312 is integrally disposed on the connecting plug 31, the connecting plug 31 is inserted into the through hole, when a step surface of the positioning ring 312 abuts against a side surface of the heating base 21, the connecting plug 31 cannot move inside the heating wall, and the positioning ring 312 plays roles of positioning and limiting. When the connection plug 31 is fitted in the through hole, the end of the connection plug 31 at this time protrudes to the inside of the heating seat 21. So that the connecting plug 31 can be elastically abutted with the baby bottle 4 when the baby bottle 4 is put into the heating seat 21.

Referring to fig. 1 to 4, two screws 34 are fixed on the outer side wall of the heating base 21 in the diameter direction of the heating base 21, and the screws 34 are symmetrically arranged on both sides of the connecting plug 31. A pressing plate 33 is slidably arranged on one side of the screw rod 34, which is far away from the heating seat 21, of the connecting plug 31, and a locking cap is in threaded connection with one side of the screw rod 34, which is far away from the connecting plug 31, of the pressing plate 33. When the connecting plug 31 is fitted to the heating base 21, the locking cap is rotated so that the pressing plate 33 restrains the connecting plug 31 on the heating base 21, preventing the connecting plug 31 from being detached from the heating base 21.

The implementation principle of the above embodiment is as follows: after the feeding bottle 4 and the connecting plug 31 are elastically butted, the groove 311 is arranged into a closed space, and the temperature is measured in the closed space, so that the measured temperature is more accurate.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
