Description

Technical Field

[0001] This utility model relates to the field of infant and child product equipment, and mainly to a sterilizer with an automatic water filling structure. Background Technology

[0002] A sterilizer, also known as a baby bottle sterilizer, is a device specifically designed for sterilizing baby bottles and baby tableware. It typically uses hot steam sterilization combined with drying to provide sterilization and drying treatment for baby products such as bottles, nipples, and toys.

[0003] Existing sterilizers consist of a main unit, a heating pot with a heating plate on the main unit, and a sterilization drying pot above the heating pot. During use, water is manually added externally to the heating pot. The heating plate generates steam, which is used to sterilize the baby products placed in the sterilization drying pot. After the water in the heating pot has evaporated, the heating plate further dries the baby products. Existing sterilizers rely on manual water addition, which is inconvenient and results in inaccurate water volume. Furthermore, continuous sterilization requires supervision, making them inconvenient and providing a poor user experience. Utility Model Content

[0004] The present invention aims to at least solve the technical problem that existing sterilizers rely on manual water addition during use, which is inconvenient. It proposes a sterilizer with an automatic water addition structure to achieve automatic water addition and replenishment during use, thereby improving the convenience of use.

[0005] This utility model proposes a sterilizer with an automatic water-filling structure, including a pot base, a control circuit board disposed within the pot base, a heating pot disposed on the pot base, and a sterilization and drying pot disposed above the heating pot. The heating pot includes a water-holding tray and a heating plate located at the bottom of the water-holding tray. An automatic water-filling structure is provided above the heating pot, including a water tank and an electrically controlled water valve. The electrically controlled water valve is connected to the water tank and the water-holding tray through a first drain pipe and a second drain pipe, respectively. A first water level detector and a second water level detector are respectively provided at different heights of the water-holding tray. The electrically controlled water valve, the first water level detector, and the second water level detector are all electrically connected to the control circuit board. The control circuit board controls the electrically controlled water valve to add water to the water-holding tray and to warn of water shortage in the water tank based on the first water level detector and the second water level detector.

[0006] In some preferred embodiments, the electrically controlled water valve is located below the water tank, and both the first drain pipe and the second drain pipe are vertically or inclined, with the lower end of the second drain pipe located above the water tray.

[0007] In some preferred embodiments, the water tray adopts an arc-shaped or inclined tray structure, and the heating plate is eccentrically located on one side of the water tray.

[0008] In some preferred embodiments, the lower end of the second drain pipe is located on the opposite side of the water tray away from the heating plate.

[0009] In some preferred embodiments, the water tank is located on the outer side of the sterilization and drying pot, away from the heating plate.

[0010] In some preferred embodiments, the electrically controlled water valve is a solenoid valve.

[0011] In some preferred embodiments, both the first water level detector and the second water level detector employ detection probes.

[0012] In some preferred embodiments, both the first drain pipe and the second drain pipe are made of silicone tubing.

[0013] In some preferred embodiments, the bottom of the sterilizing and drying pot is provided with a tray located above the heating pot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The sterilizer disclosed in this utility model features an automatic water-filling structure above the heating pot. This structure, controlled by a control circuit board, operates an electrically controlled water valve based on first and second water level detectors positioned at different heights within the heating pot. When the valve is open, water in the tank utilizes its own gravitational potential energy to flow through a first drain pipe, the electrically controlled water valve, and a second drain pipe into a water tray, automatically replenishing the heating pot without manual intervention, thus improving the user experience. Furthermore, the automatic water-filling structure eliminates the need for a water pump; instead, water flows downwards into the heating pot using its own gravitational potential energy during the replenishment process, resulting in a simple structure and low implementation cost.

[0019] To further illustrate the technical means and effects adopted by this application to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "an embodiment" or "an embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0020] A sterilizer is a household appliance primarily used for steam sterilization and heating drying of baby products. It has two modes: a sterilization mode that heats water to generate steam for sterilization, and a drying mode that only provides heating and drying without generating steam.

[0021] Combination Figures 1-3 As shown, the sterilization pot disclosed in this utility model includes a pot base 1, a control circuit board 11 disposed in the pot base 1, a heating pot 2 disposed on the pot base 1, and a sterilization and drying pot 3 disposed above the heating pot 2. The heating pot 2 includes a water tray 21 and a heating plate 22 located at the bottom of the water tray 21. The heating plate 22 heats up to generate heat when energized. In the sterilization working state, it heats the water in the water tray 21 to generate steam for sterilization. In the drying working state, it generates heat for heating and drying treatment.

[0022] The sterilizer disclosed in this utility model has an automatic water filling structure above the heating pot 2. The automatic water filling structure includes a water tank 4 and an electrically controlled water valve 5. The electrically controlled water valve 5 is connected to the bottom of the water tank 4 through a first drain pipe 61 and to a water tray 21 through a second drain pipe 62. The lower end of the second drain pipe 62 is located above the water tray 21. Thus, when the electrically controlled water valve 5 is in the conducting state, the water in the water tank 4 can use its own gravitational potential energy to flow into the water tray 21 through the first drain pipe 61, the electrically controlled water valve 5 and the second drain pipe 62, thereby realizing the automatic water filling and replenishment operation for the heating pot 2.

[0023] The electrically controlled water valve 5 is electrically connected to the control circuit board, which controls the opening and closing of the valve to control the water supply to the heating pot. The electrically controlled water valve 5 is typically implemented using a solenoid valve, which is simple in structure and reliable in operation.

[0024] A first water level detector 23 and a second water level detector 24 are respectively installed at different heights in the water-holding pan 21. The first water level detector 23 and the second water level detector 24 are usually detection probes, which are simple in structure and low in implementation cost. For example: the first water level detector 23 is set in the water-holding pan 21 near the heating plate 22, so that it can be used to detect the minimum working water level of the heating pot 2 in the disinfection operation mode; the second water level detector 24 is located at a greater height from the heating plate 22, so that it can be used to detect the maximum working water level of the heating pot 2 in the disinfection operation mode.

[0025] Both the first water level detector 23 and the second water level detector 24 are electrically connected to the control circuit board 11 via a feedback circuit. During the sterilization process, the control circuit board uses the first and second water level detectors 23 and 24 to control the on / off state of the electrically controlled water valve 5, thereby controlling the water replenishment operation of the heating pot 2. As is well known to those skilled in the art, by applying a detection voltage or detection current to the first water level detector 23 and the second water level detector 24 respectively, the control circuit board can make judgments based on changes in the detection voltage or detection current through the feedback circuit. Specifically, the control circuit board controls the electrically controlled water valve 5 based on the first and second water level detectors 23 and 24 as follows:

[0026] 1. When the sterilizer is started and enters the sterilization working state, the control circuit board sends a conduction control signal to the electrically controlled water valve 5 to switch the electrically controlled water valve 5 from the closed state to the open state, so that the water in the water tank 4 can use its own gravity potential energy to add water to the water tray 21 through the electrically controlled water valve 5. Alternatively, when the sterilizer needs to replenish water multiple times to provide multiple steam sterilization treatments during the sterilization working state, when the water level in the water tray 21 is lower than the first water level detector 23, the control circuit board sends a conduction control signal to the electrically controlled water valve 5 to switch the electrically controlled water valve 5 from the closed state to the open state, so that the water in the water tank 4 can use its own gravity potential energy to add water to the water tray 21 through the electrically controlled water valve 5.

[0027] 2. As the water level in the water tray 21 increases, when the water level reaches the second water level detector 24, the first water level detector 23 and the second water level detector 24 are connected by water. At this time, the control circuit board sends a shut-off control signal to the electric water valve 5 so that the electric water valve 5 switches from the on state to the off state, stops adding water to the heating pot 2, and the control circuit board also controls the heating plate 22 to start heating.

[0028] 3. Since the flow rate of water added to water tank 4 through the electrically controlled water valve 5 is constant, if the control circuit board does not detect the conditions for triggering the shutdown control signal by the first water level detector 23 and the second water level detector 24 through water conduction after the preset time of issuing the conduction control signal during the water addition process, it indicates that there is not enough water flowing into the water tray 21 in water tank 4. Then the control circuit board judges that water tank 4 is short of water, and the water shortage warning circuit of the control circuit board issues an alarm message to prompt that water tank 4 needs to be replenished in time.

[0029] To ensure that the water in the water tank 4 can flow quickly into the water tray 21 under its own weight, controlled by the electric water valve 5, the electric water valve 5 is located below the water tank 4, and the first drain pipe 61 and the second drain pipe 62 are both set vertically or at an angle, so that the water in the water tank 4 can flow smoothly into the water tray 21 under its own weight along the first drain pipe 61, through the electric water valve 5, and through the second drain pipe 62.

[0030] The first drain pipe 61 and the second drain pipe 62 are typically made of silicone tubing, which is flexible, easy to wire, and durable.

[0031] The water tray 21 adopts an arc-shaped or inclined tray structure, with the heating plate 22 eccentrically positioned on one side of the water tray 21, and the second drain pipe 62 located on the other side of the water tray 21 away from the heating plate 22. When the sterilizer is in sterilization mode, cold water supplied from the second drain pipe 62 flows into the water tray 21 from the end away from the heating plate 22. As the cold water flows along the arc-shaped or inclined tray towards the heating plate 22, it is heated by the tray, generating steam more quickly compared to applying cold water directly above the heating plate 22. When the sterilizer is in drying mode, the heat generated by the heating plate 22 is kept away from the second drain pipe 62, preventing the second drain pipe 62 from aging due to excessive heating.

[0032] Because the heating plate 22 is located at the bottom of the water tray 21, there is a relatively high water level above the heating plate 22. Simultaneously, because the heating plate 22 is offset to one side of the water tray 21, the weight of the water in the heating pot 2 is offset to the area above the heating plate 22. Correspondingly, the water tank 4 is positioned on the outer side of the sterilization and drying pot 3, away from the heating plate 22. By positioning the heating plate 22 and the water tank 4 far apart, the weight of the heating plate 22 and the water tank 4 is more evenly distributed on the sterilization pot. This prevents uneven weight distribution after water is added to the water tank 4, which could lead to instability and tipping over, thus improving safety during use.

[0033] In addition, the bottom of the sterilizing and drying pot 3 is equipped with a tray 31 located above the heating pot 2. Baby products such as bottles that need to be sterilized are placed on the tray 31 to complete the sterilization and drying process.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
