SUMMERY OF THE UTILITY MODEL

The utility model aims at the problems in the prior art and provides a feeding bottle sterilizer which is convenient to use, convenient to drain and clear in clear water consumption.

In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: a feeding bottle sterilizer is characterized by comprising a main body, a switch mechanism and a heating device, wherein the switch mechanism and the heating device are arranged on the main body; the switch mechanism is electrically connected with the heating device; the heating device is arranged at the bottom of the containing cavity and is turned on and off through the switch mechanism. When the feeding bottle sterilizing device is used, a plurality of feeding bottles are placed in the accommodating cavity, then a proper amount of clean water is placed according to the water flow scale marks, when too much clean water is poured carelessly, the clean water flows out from the discharge hole, then the cover is covered, the feeding bottle sterilizer is electrified, then the heating device is turned on through the switch mechanism for heating and sterilizing, hot steam generated in the heating process is discharged from the discharge hole, the sterilizing operation can be completed after a period of time, and when the heating device continues to heat, the clean water in the accommodating cavity can be completely evaporated, and then the feeding bottles can be dried; more clear water is placed through the scale marks, the feeding bottle filled with milk can be subjected to nutrition steaming operation, only the heating time of the heating device needs to be controlled, and the heating device is turned off through the switch mechanism at a certain time. The above arrangement has the advantages of convenient use, convenient drainage and clear use amount of clear water, and the whole sterilizer has simple and compact structure. The heating device is a component assembled by common heating pipes, can be purchased from the market, and is not described herein again.

Furthermore, the drain hole and the scale marks are arranged on the convex part on the cavity, the drain hole is uniformly arranged in the upper area of the convex part, and the scale marks are arranged below the drain hole. When the cover is used, the cover is generally airtight and sealed, so that water vapor can be discharged from the discharge hole, redundant clear water can be discharged from the discharge hole, and the cover has two functions.

Further, the bulge below have and be used for drainage and carminative drainage groove, the drainage groove including setting up in the drainage strip of main part medial surface, the drainage strip set up in drainage groove both sides. When vapor or clear water flow in the drainage groove from the discharge hole, the drainage groove can guide vapor or clear water, the drainage strip can further promote the drainage effect, concentrate vapor or clear water to a direction discharge, and the drainage strip sets up in the main part medial surface, can also play the effect of strengthening main part medial surface intensity, set the strengthening rib and the drainage strip of main part below medial surface to same size, then evenly set up at main part below medial surface, not only can save the design cost, can also make the intensity at each position of main part more even, be difficult for damaging.

Furthermore, the cavity comprises a supporting edge positioned in the upper area of the cavity, the upper surface of the supporting edge is flush with the upper surface of the protruding part, and the width of the supporting edge is smaller than that of the protruding part. The lid can be placed simultaneously on supporting limit and bulge for the bulge has the effect of a support again more, and the bulge width will be greater than the width on supporting the limit moreover, and the bulge can strengthen the supporting effect on supporting the limit, makes the supporting effect of supporting the limit to the lid better.

Furthermore, the main body comprises a fixing column arranged at the bottom of the main body and a switch mounting hole arranged on the side face of the main body, and the fixing column is used for fixing the switch mechanism through a connecting piece; the fixed column peripheral wall on still be equipped with the strengthening rib. Switch mechanism passes through the switch mounting hole and the connecting piece such as fixed column and screw is fixed in the main part, easy dismounting is equipped with the strengthening rib on the periphery wall of fixed column moreover, therefore the intensity of fixed column can be guaranteed.

Furthermore, the switch mechanism comprises a shell and a knob rotatably arranged on the shell, a circuit board is further arranged in the shell, a potentiometer is arranged on the circuit board, and the knob is in stop fit with the potentiometer; the knob on be equipped with canceling release mechanical system, the circuit board on still be equipped with the gear circle, the gear circle be equipped with a plurality of with canceling release mechanical system complex gear groove, the gear groove evenly set up along gear circle circumferencial direction, when canceling release mechanical system rotates the gear groove region along with the knob, canceling release mechanical system reset and insert the gear groove and realize the gear switching of knob. When the potentiometer is used, the knob is rotated, the potentiometer is connected with the rotation knob, and the potentiometer serves as a variable potentiometer and is used for adjusting the voltage and the current, so that the resistance value of the potentiometer is changed when the potentiometer is rotated, the voltage and the current on the circuit board are changed, the circuit board outputs different signals according to different voltages and different currents, and function switching is achieved. Compared with the structure of a knob switch, the knob switch saves a plurality of springs and moving and static contact pieces, greatly reduces the number of parts, has the advantages of simple structure and high installation efficiency, and the potentiometer is connected with the knob only by the potentiometer to limit the rotation of the knob, so when the knob rotates, the damping between the potentiometer and the knob is smaller, the knob rotates smoothly, and the reset mechanism is arranged, when the reset mechanism rotates along with the knob, the reset mechanism rotates to the position of the gear groove, because of the reset mechanism, the reset mechanism slides into the gear groove, the reset mechanism impacts the bottom surface of the gear groove to make a sound, when the knob continues to rotate, the reset mechanism slides out of the gear groove, the reset mechanism is compressed, the knob rotates continuously, when the reset mechanism slides into the gear groove, the sound is made, namely, one gear switching is completed, the knob is clear, so that the knob is very rhythmic when rotated, the knob can make a sound of clicking, and when the reset mechanism is abutted against the gear ring and rotates along with the knob, the reset mechanism has pressure on the gear ring, so that the friction force is increased when the knob rotates, the knob cannot easily slide when rotated, and the defect that the damping between the potentiometer and the knob is too small is overcome. The potentiometer and the circuit board are standard components commonly found in the market, and are not described in detail here.

Furthermore, a connecting seat is detachably arranged on the knob, and an upper rotating shaft for inserting into the potentiometer is arranged on the connecting seat; reset mechanism set up on the connecting seat, reset mechanism include the installation axle that cavity set up, install spring and setting element in the installation axle, the spring both ends connect installation axle and setting element respectively.
