Embodiment

The utility model is described further with reference to the accompanying drawings and examples.

With reference to shown in Fig. 1-Fig. 4, the utility model proposes a kind of milk warming device, which includes the base with heater 1st, the body 2 on base 1, the body 2 have the heating chamber 21 for accommodating feeding bottle, sensing detection device are equipped with base 1, The sensing detection device include sensing device 4, by stent 3 that sensing device 4 is fixed on the bottom of chamber plate 22 of heating chamber 21, be arranged Sealing ring 6 on sensing device 4.

The sensing device 4 include metal shell 41 and be encapsulated in metal shell 41 sensor (such as sensor for heat Quick resistance), which has 2 independent lead ends 43, and the middle part of the metal shell 41 has screens portion 42.The stent 3 The fixed part 33 extended including rack body 31 and from rack body 31, the fixed part 33 are equipped with mounting hole 34, the branch Frame body 31, which is equipped with, allows the lead end 43 of sensor 4 or even the bottom of metal shell 41 passes through and allows the screens of metal shell 41 The limit hole 32 that portion 42 can not pass through, the limit hole 32 are delthyrium, four corner apertures, five corner apertures or circular hole.

In order to allow sensing device 4 more accurately to detect 21 intrinsic parameter of heating chamber (such as temperature), therefore in heating chamber 21 Bottom of chamber plate 22 be equipped with mounting hole 23, when sensing device 4 is fixed on bottom of chamber 22 lower face of plate by stent 3, metal shell 41 upper end can be stretched into heating chamber 2 to pass through the mounting hole 23.

In order to allow metal shell 41 upper end stretch into heating chamber 2 after do not influence to place feeding bottle etc. in heating chamber 2 and produce Interference, therefore the height for setting the upper end of metal shell 41 to stretch into heating chamber 2 is 2-4mm.The upper end of the metal shell 41 It is the cylinder of 2.8-4.2mm for diameter.Also, mounting hole 23 is arranged on bottom of chamber plate 22 and close to the outer casing inner wall of body 2 Position, distance is advisable no more than 2cm between the upper end of the metal shell 41 and the outer casing inner wall of body 2.

Due to that can have water mist or water droplet in heating chamber 2, water falls into base 1 by mounting hole 23 in order to prevent, therefore in gold The upper end for belonging to housing 41 is arranged a sealing ring 6, prevents water droplet from entering base 1 from mounting hole 23 by sealing ring 6.

The lead end 43 of sensing device 4 is passed through into limit hole 32, can not be passed through due to the screens portion 42 of metal shell 41 Limit hole 32, therefore sensing device 4 is held in realize on rack body 31 by screens portion 42 and is installed on stent 3. Then, sealing ring 6 is set in the upper end of metal shell 41, screw 5 is reused and passes through mounting hole 34 from bottom to top by stent 3 22 lower face of bottom of chamber plate of heating chamber 21 is fixed on, completes the assembling to sensing detection device, assembly manipulation very simple.Work as biography When induction device 4 needs to safeguard replacement, it is only necessary to base 1 is opened, screw 5 is turned on and unloads stent 3 from 22 lower face of bottom of chamber plate, from Sensing device 4 is removed on stent 3 to be safeguarded or replaced.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
