Description

Constant temperature water tank

Technical Field

The utility model relates to a technical field of milk machine accessory, more specifically relate to a constant temperature water tank.

Background

The traditional milk powder brewing method generally adopts manual brewing, milk powder is poured into a feeding bottle, then hot water is manually poured into the feeding bottle to fill milk liquid prepared by proper proportion of the milk powder and the water, and the problem of the mode is that: firstly, the water temperature is difficult to control, the baby is easily scalded when the temperature is too high, and the milk in the milk bottle is cooled when the temperature is too low; secondly, the milk brewed manually is often not uniformly mixed, and the milk powder is not broken at part and is agglomerated, so that the eating of the baby is affected; moreover, the ratio of the milk powder and the water is not easy to control, and the milk liquid possibly blended is too thin or too thick, so that the milk is not easy to digest or is easy to hungry after the infant eats the milk. Therefore, various milk powder filling machines appear in the market, but the water in the constant temperature water tank of the existing milk powder filling machine generally achieves the constant temperature effect by arranging a heat insulation layer in the constant temperature bin for heat insulation, and the constant temperature effect is poor due to the design, so that improvement is needed.

SUMMERY OF THE UTILITY MODEL

In view of this, the present invention provides a constant temperature water tank with improved constant temperature effect.

In order to solve the technical problem, the technical scheme of the utility model is that: the utility model provides a constant temperature water tank, includes the thermostat body, is equipped with water inlet and delivery port on the thermostat body, is equipped with the first NTC temperature sensor that is used for detecting the temperature of water inlet in the water inlet department of thermostat body, is equipped with the second NTC temperature sensor that is used for detecting the temperature of mixing water in the thermostat body inside, is equipped with the PTC heater that heats the water in the thermostat body in the bottom of thermostat body.

Further, in order to balance the flow of the internal water, the side wall of the constant temperature box body is provided with air balance holes, and the air balance holes ensure that the inner wall of the constant temperature box body is communicated with the outside.

Further, in order to prevent water leakage, the air balance hole must be provided at a position higher than a high water level inside the oven body.

Furthermore, in order to facilitate later-stage replacement, the second NTC temperature sensor is positioned in a water outlet of the thermostat box body.

Preferably, the constant temperature box body is vertically arranged.

Furthermore, the milk brewing machine is convenient to fix, and one side of the constant temperature box body is fixed in the milk brewing machine shell through the constant temperature box body fixing frame.

Compared with the prior art, the utility model discloses beneficial technological effect mainly embodies: through the temperature condition that acquires two different positions, improve the real-time detection to the temperature of the inside water of thermostated container body to water through the PTC heater in to the thermostated container body heats, finally guarantee that the water in the thermostated container body is in constant temperature state all the time, consequently further improve the constant temperature effect.

FIG. 1 is a perspective view showing the structure of a constant temperature water tank in the present embodiment 1;

fig. 2 is an exploded view of the structure of a constant-temperature water tank in this embodiment 1.

Wherein: a thermostat case 1; a water inlet 2; a water outlet 3; a first NTC temperature sensor 4; a second NTC temperature sensor 5; a PTC heater 6; air balance holes 7; a fixing frame 8 of the constant temperature box body.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example 1:

as shown in fig. 1 to 2, the constant temperature water tank disclosed in the present embodiment includes a constant temperature tank body 1, a water inlet 2 and a water outlet 3 are provided on the constant temperature tank body 1, a first NTC temperature sensor 4 for detecting a temperature of the water inlet is provided at the water inlet 2 of the constant temperature tank body 1, a second NTC temperature sensor 5 for detecting a temperature of mixed water is provided inside the constant temperature tank body 1, and a PTC heater 6 for heating water in the constant temperature tank body 1 is provided at a bottom of the constant temperature tank body 1.

Further, in order to balance the flow of the internal water, the side wall of the thermostat body 1 is provided with an air balance hole 7, and the air balance hole 7 ensures that the inner wall of the thermostat body 1 is communicated with the outside.

Further, in order to avoid water leakage, the air balance hole 7 must be provided at a position higher than a high water level inside the thermostat case 1.

Further, in order to facilitate later replacement, the second NTC temperature sensor 5 is located in the water outlet 3 of the incubator body 1, and the air balance hole 7 is located at the top end of the incubator body 1 in this embodiment.

Preferably, the thermostat body 1 is vertically arranged.

Further, be convenient for fixed, one side of the constant temperature box body 1 is fixed in the milk machine casing through constant temperature box body mount 8, in this embodiment constant temperature box body 1 pass through the screw fixation on constant temperature box body mount 8, later stage constant temperature box body mount 8 passes through the screw fixation in the milk machine casing, realizes that the installation is fixed.
