The main body 11 further comprises a circuit board and a heating circuit (not shown), wherein the circuit board is used as a master control core of the milk warmer 10 and controls the program operation of the milk warmer 10, and the circuit board can be disposed between the main body 110 and the water storage liner 112 and fixed relatively to the main body 110.

Referring to fig. 3 and 4, fig. 3 shows a schematic view of another perspective of the milk warmer shown in the application for an exemplary embodiment; fig. 4 shows a cross-sectional view of a milk warmer shown in an exemplary embodiment of the present application.

The heating circuit comprises a heating disc 13 and a control switch 14, the control switch 14 is connected with a circuit board, and the circuit board can control the heating circuit to be switched on and off according to the on-off signal of the control switch 14. When the control switch 14 is closed, the heating circuit is turned on, and the heat generating plate 13 can heat the water stored in the water storage inner container 112.

In the example shown in fig. 3 to 4, the heat generating plate 13 is disposed at the bottom of the body 11, and the bottom wall 112d of the water storage inner container 112 is provided with an opening from which the heat generating components of the heat generating plate 13 extend into the interior of the water storage inner container 112, at which the upper end surface 130 of the heat generating components is in sealing engagement with the bottom wall 112d of the water storage inner container 112 as a supplementary bottom wall of the water storage inner container 112 at the opening. In this example, the heat generating components may directly contact the water, thereby rapidly heating the water in the water storage bladder 112, improving heating efficiency. The first sealing ring 15 is provided at a portion where the heat generating plate 13 is joined to the water storage inner 112, thereby achieving sealing engagement of the upper end surface 130 of the heat generating component with the bottom wall of the water storage inner 112 to prevent water in the water storage inner 112 from leaking.

Referring to fig. 2 and 4, in particular, the machine body 10 further includes a working component 16, and the working component 16 is detachably installed in the machine body 11, more specifically, in the water storage liner 112, and is used for placing a vessel to be heated (e.g., a feeding bottle) or food (e.g., eggs). That is, the working assembly 16 may be, but is not limited to, a sterilization rack, a milk warming rack, a steamboat, or the like.

In this example, the inner wall of the water storage tank 112 is provided with a flange 112a, the flange 112a is higher than the bottom wall of the water storage tank 112, and the working unit 16 is lapped on the upper surface of the flange 112 a. A second sealing ring 17 is further disposed in the water storage tank 112, the second sealing ring 17 is used for sealing a gap between the working element 16 and the water storage tank 112, in this example, the second sealing ring 17 is sealed between the side wall of the flange 112a and the working element 16.

The operating assembly 16 is arranged to trigger the control switch 14 to close when mounted to the body 11 and to trigger the control switch 14 to open when removed. That is, the control switch 14 can be triggered to switch between on and off by installing the working assembly 16 in the machine body 11 and removing the working assembly 16 from the machine body 11, so that the control of the on and off states of the control switch 14 is realized through the working assembly 16.

As can be seen from the above description, in the using process of the milk warmer 10, the feeding bottle needs to be placed on the working component 16, and the control switch 14 can be triggered to be closed only after the working component 16 is installed on the body 11, otherwise, the heating plate 13 is not heated, so that the phenomenon that the feeding bottle 10 is in direct contact with the heating plate 13 when being heated does not occur, the phenomenon that the feeding bottle is in direct contact with the heating plate 13 to cause glue melting is avoided, and the use safety of the milk warmer 10 is improved.

The specific manner in which the operating assembly 16 triggers the control switch 14 to turn on is not limited in this application. As an example, referring to fig. 3, the control switch 14 includes a magnetic control switch, and correspondingly, the working assembly 16 includes a magnetic member 161, the magnetic control switch is closed under the magnetic field of the magnetic member 161, and the circuit board controls the heating circuit to be turned on after receiving the closing signal. The magnetic control switch is closed under the action of a magnetic field, and the closing mode is relatively simple.

Specifically, the magnetic control switch may be a reed switch, which is disposed on the flange 112a, and the magnetic member 161 is disposed at a position where the working component 16 is overlapped on the flange 112a, and the magnetic member 161 is disposed opposite to the magnetic control switch. When the working element 16 is attached to the flange 112a, the magnetic control switch is triggered to close by the magnetic field of the magnetic member 161. The magnetic member 161 may be a permanent magnet or an electromagnet, and the former structure is simpler in comparison.

In the above embodiment, two magnetic members 161 may be provided. Because the water storage inner container 112 is of an oval structure, the shape of the working assembly 16 is correspondingly oval, when the working assembly 16 is installed in the water storage inner container 112, the direction is not unique, and two installation postures can be separated by 180 degrees, therefore, the magnetic parts 161 are respectively arranged at the two ends of the working assembly 16 in the length direction, the installation posture of the working assembly 16 does not need to be distinguished, and the control switch 14 can be triggered to be closed in the two installation postures.

As another example, the working assembly 16 may also include a magnetic conductor made of a magnetic material, such as pure iron, stainless steel, or the like. The magnetic element in the magnetic control switch can be triggered to realize closing in the process of magnetizing the magnetizer.

Referring to fig. 5, the control switch 14 comprises a mechanical switch that can be closed by the contact force of the working assembly 16. Specifically, the mechanical switch is disposed above the flange 112a and is relatively fixed to the water storage inner container 112, and when the working element 16 is overlapped with the flange 112a, the end of the working element 16 touches the mechanical switch to trigger the mechanical switch to be turned on. The mechanical switch can generate a closing stroke under the action of external force, and can be stably and reliably kept in a closing state under the state that the external force is always acted.

Referring again to fig. 2 and 4, the working assembly 16 includes two spray tubes, namely a first spray tube 160a and a second spray tube 160b, in this example, the first spray tube 160a has a greater extension than the second spray tube 160b, the first spray tube 160a can be used for cleaning the feeding bottle, and the second spray tube 160b can be used for cleaning the nipple.

The first and second injection pipes 160a and 160b are opened downward and communicate with the water storage chamber 20 located below the working unit 16, and the water storage chamber 20 occupies a bottom space in the water storage tank 112. The water or steam heated in the water storage chamber 20 ascends along the first and second injection pipes 160a and 160b, respectively, by a siphon action and is injected through the injection holes opened at the outer walls of the first and second injection pipes 160a and 160 b. The feeding bottle is hung in an upside-down manner on the top of the first spraying tube 160a, the inner wall of the feeding bottle can be washed and sterilized by the hot water sprayed from the first spraying tube 160a, the inner wall of the nipple can be washed and sterilized by the nipple hung on the top of the second spraying tube 160b, and the inner wall of the nipple can be washed and sterilized by the hot water sprayed from the second spraying tube 160 b.

As will be readily appreciated, the waste water generated after washing the feeding bottle and nipple can flow back to the working assembly 16. to facilitate collection of the waste water, the working assembly 16 further includes a waste water collection groove 162. the waste water collection groove 162 allows the working assembly 16 to form a recess on the upper surface thereof, so that temporary storage of the waste water can be achieved, and the waste water can be prevented from overflowing.

Further, the machine body 11 further includes an upper cover 18 covering the sewage collecting tank 162, and a third sealing ring 19 is disposed at a joint of the upper cover 18 and the sewage collecting tank 162, and the third sealing ring 19 may be an O-ring to prevent sewage from flowing out from the joint of the upper cover and the sewage collecting tank 162. Specifically, an annular groove is formed in the side wall of the upper cover 18, and the third sealing ring 19 is arranged in the annular groove, so that the sealing reliability is improved.

The upper cover 18 includes a sewage receiving surface 180, and the sewage receiving surface 180 is opened with a sewage passing hole 180a communicating with the sewage collecting tank 162, and sewage generated after washing the feeding bottle and the nipple falls on the sewage receiving surface 180 and flows into the sewage collecting tank 162 through the sewage passing hole 180 a.

In this example, the sewage receiving surface 180 is formed as a curved surface having a low central region and a high edge region, which guides the sewage flowing down into the sewage receiving surface 180, so that the sewage can rapidly enter the sewage collecting tank 162 through the sewage passing hole 180 a. In addition, the sewage receiving surface 180 is further provided with through holes 180b through which the first and second injection pipes 160a and 160b extend, and the number of the through holes 180b is matched with the number of the injection pipes.

The milk warming device 10 provided by the present application can also clean and sterilize the outer wall of the feeding bottle, specifically, please refer to fig. 2 and 4 again, the water storage liner 112 includes a plurality of raised portions 112b, at the position of each raised portion 112b, the water storage liner 112 is a double-layer structure, the inside is formed into a cavity, the opening of the cavity is communicated with the water storage cavity 20, and the inner wall is provided with a plurality of water spraying holes 112 c. When the water in the storage chamber 20 is heated, boiling water or steam may enter the chamber and rise up the chamber to be sprayed from the spout 112c to rinse and disinfect the outer walls of the bottle and nipple. The number of the ridges 112b is not limited, and may be selected according to the actual situation.

The arrows in fig. 4 and 5 indicate the flow direction of the boiling water and/or steam formed after the water in the water storage chamber 20 is heated.

Referring again to FIG. 5, in order to further improve the safety of the milk warmer 10 during use, the milk warmer 10 further includes a temperature sensor 30, the temperature sensor 30 is connected to a circuit board, and the circuit board controls the heating circuit to be turned on or off according to a temperature signal sensed by the temperature sensor. For example, when the temperature sensor senses a temperature decrease in the water storage inner container 112, the circuit board controls the heating circuit to be turned off according to the temperature signal, so as to avoid over-heating.

In the example shown in fig. 5, the sensing head of the temperature sensor 30 is inserted into the water storage chamber 20 from the bottom wall of the water storage bladder 112. That is, if the water level in the water storage chamber 20 is lowered, the sensing head of the temperature sensor 30 is exposed to the water surface and senses the temperature lowering, and at this time, the circuit board controls the heating circuit to be turned off according to the temperature signal. The scheme can timely and accurately sense the temperature change and improve the sensing sensitivity.

In another example, the sensing head of the temperature sensor 30 may be disposed outside the water storage inner container 112, and at this time, the sensing head of the temperature sensor 30 may be attached to the outer wall of the water storage inner container 112. Therefore, the temperature change can be timely and accurately sensed.

Further, in order to avoid the heating circuit being turned off after the water in the water storage cavity 20 is dried, the upper end surface 130 of the heat generating component of the heat generating plate 13 is arranged lower than the bottom wall of the water storage inner container 112, and the height difference is set to be H. Thus, when the water level drops and the sensing head of the temperature sensor 30 is out of the water and senses that the temperature is low, a portion of water remains on the heat generating tray 13 and does not burn out before the power is turned off, thereby further improving the safety of the milk warmer 10. The specific shape of the upper end surface 130 of the heat generating component is not limited, and may be a plane or a concave curved surface as long as the upper end surface is the lowest surface in the water storage bladder 112.

In one example, the upper end surface 130 of the heat generating component of the heat generating plate 13 is set to be flat and 3mm to 10mm lower than the bottom wall of the water storage inner container 112, and the height difference H can ensure that a part of water is still left on the upper end surface 130 before the heating circuit is disconnected, so as to avoid over-heating. In a specific example, the upper end surface 130 of the heat generating plate 13 may be 5mm lower than the bottom wall of the water storage bladder 112.

Although the present application has been described with reference to the milk warmer 10, other types of disinfection devices, such as a disinfection machine and a dryer, may be configured substantially the same as the working assembly 16 of the milk warmer 10 and adapted to the specific application scenario, the type of the dish, etc., in order to avoid the phenomenon that the dish and the food material are in direct contact with the heat generating plate.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
