Description

Technical Field

[0001] The utility model relates to the technical field of water boilers, in particular to a water boiler. Background Art

[0002] At present, when parents of infants prepare milk powder, they usually use water heated in a kettle, and then wait for the water temperature to drop to between 40-50°, pour an appropriate amount of water into the bottle, and then add milk powder according to the baby's food intake, and manually shake the bottle to complete the preparation of the milk powder.

[0003] In the prior art, regarding the brewing of milk powder, a Chinese utility model with a publication number of CN214905941U proposes a "liquid heating container and milk mixer", which uses a water pump, a drain pipe and a water outlet pipe to pump water from the kettle body to the water outlet and inject it into the milk bottle from the water outlet.

[0004] However, in actual use, after the water pump pumps out the water, the water inside the water outlet pipe cannot be completely emptied, and some water will still stagnate in the pipe. After a long period of stagnation, the water temperature inside the water pipe will drop to a level close to room temperature. When the water with a temperature suitable for brewing milk powder inside the kettle comes out of the kettle and mixes with the water in the water pipe, it is easy to affect the overall water temperature, causing the water temperature to deviate, making the water temperature not meet the optimal range for brewing milk powder, and there is a temperature difference between the discharged water and the water inside the kettle. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution that can solve the temperature difference of water after the low-temperature water stagnated for a long time in the pipeline is mixed with the water body.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a water boiler, comprising a main body and a heating device, a heating base is installed on the main body, a kettle is arranged on the heating base, a water outlet is formed on the main body, a water outlet pipe is arranged between the kettle and the water outlet, so that the water inside the water outlet pipe is heated by the heating device; a water pump is also arranged on the main body, and the water pump is used to transport the water in the kettle to the water outlet through the water outlet pipe.

[0007] As a further solution of the utility model: the water outlet pipe is divided into a water suction pipe used to connect the water pump with the kettle, and a drainage pipe used to connect the water pump with the water outlet.

[0008] As a further solution of the utility model: the heating device includes a heating body arranged on the water suction pipe and / or the drainage pipe, a temperature sensor a acting on the water suction pipe and / or the drainage pipe, an electromagnetic valve installed inside the water outlet, and a control chip and a temperature sensor b inside the kettle.

[0009] As a further solution of the utility model: the control chip is electrically connected to the water pump, the heating element, the temperature sensor a, the temperature sensor b and the solenoid valve respectively.

[0010] As a further solution of the utility model: the heating element is a flexible heating element.

[0011] As a further solution of the utility model: a water valve connected to the water pumping pipe is arranged on the heating base.

[0012] As a further solution of the utility model: an operation panel is provided on one side of the outer surface of the main body, and the operation panel is electrically connected to the control chip.

[0013] As a further solution of the utility model: a water filling area is formed on the main body, a groove is opened at the bottom of the water filling area, and a water filling frame is placed on the groove.

[0014] Compared with the prior art, the beneficial effects of the present technical solution are as follows: when part of the water body stays in the water pumping pipe and the drainage pipe for a long time, causing the water temperature to drop to near room temperature, the heating element is started through the operation panel, and the heat generated by the operation of the heating element causes the temperature of the water pumping pipe and / or the drainage pipe to rise, and the heat is transferred from the water pumping pipe and / or the drainage pipe to the water body inside the water pumping pipe and / or the drainage pipe. At the same time, the temperature sensor a and the temperature sensor b detect the water temperature inside the kettle and the water pumping pipe and / or the drainage pipe respectively, so that the operation panel can display the temperature of the kettle and the water pumping pipe in real time. The temperature of the water inside the pumping pipe and / or the drain pipe can be controlled to be between 40-50°, which is the optimal water temperature range for brewing milk powder. When the water pump is started again to pump out the water, the water temperature inside the kettle will not change after mixing with the previously stagnant water inside the pumping pipe and the drain pipe, thereby preventing the water from being stagnant in the pumping pipe and the drain pipe for a long time and the water temperature being too low, resulting in the overall water temperature not meeting the optimal range for brewing milk powder after the constant temperature water is mixed therewith, thereby preventing the water temperature from affecting the quality of the brewed milk powder.

[0015] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 A water boiler comprises a main body 1 and a heating device, wherein a heating base 2 is mounted on the main body 1, a kettle 201 is arranged on the heating base 2, and the kettle 201 is provided with a lid which can block the kettle 201. After the lid blocks the opening at the top of the kettle 201, the spout on the kettle 201 can be used as an outlet for pouring out the water in the kettle 201. Meanwhile, an integral kettle handle is arranged on the outer side of the kettle 201, and the kettle 201 can be taken away from the main body 1 by the kettle handle so that the kettle 201 can be used to fill water. The heating base 2 is used to heat the kettle 201 so that the water in the kettle 201 can boil.

[0028] The main body 1 is formed with a water outlet 101, and a water outlet pipe 4 is arranged between the kettle 201 and the water outlet 101 to heat the water inside the water outlet pipe 4 through a heating device. The main body 1 is also provided with a water pump 3, and the water pump 3 is used to transport the water in the kettle 201 to the water outlet 101 through the water outlet pipe 4. The water outlet pipe 4 is divided into a pumping pipe 401 for connecting the water pump 3 with the kettle 201, and a drainage pipe 402 for connecting the water pump 3 with the water outlet 101. The heating device comprises a heating element 5 arranged on the water pumping pipe 401 and / or the drainage pipe 402, a temperature sensor a6 acting on the water pumping pipe 401 and / or the drainage pipe 402, a solenoid valve 102 installed inside the water outlet 101, and a control chip and a temperature sensor b inside the kettle 201. The control chip is electrically connected to the heating element 5, the temperature sensor a6, the temperature sensor b, the solenoid valve 102, the water pump 3 and the operation panel 103. The water pumping pipe 401 and the drainage pipe 402 are high temperature resistant hoses to ensure that the water pumping pipe 401 and the drainage pipe 402 can still maintain good physical properties and chemical stability under high temperature conditions.

[0029] When the water in the kettle 201 is led out to the milk bottle (which is essentially a container for holding water, and therefore may also be other containers, such as a water cup), the control chip may be operated through the operation panel 103 to control the start and stop of the heating element 5, the temperature sensor a6, the temperature sensor b, the solenoid valve 102, and the water pump 3. At this time, the water pump 3 is started, and the water in the kettle 201 is made to flow into the water outlet 101 through the water suction pipe 401 and the drainage pipe 402, and then the water is injected into the milk bottle by the water outlet 101, thereby completing the first milk powder brewing.

[0030] After the first milk powder brewing is completed, the water pump 3 stops working. The water drawn from the kettle 201 stays in the water pumping pipe 401 and the drain pipe 402 for a long time, causing the water temperature to drop to near room temperature. At this time, the heating element 5 is started again through the operation panel 103, and the heat generated by the heating element 5 causes the temperature of the water pumping pipe 401 and / or the drain pipe 402 to rise, and the heat is transferred to the water inside the water pumping pipe 401 and / or the drain pipe 402. At the same time, the temperature sensor a6 and the temperature sensor b respectively detect the water temperature inside the kettle 201 and the water pumping pipe 401 and / or the drain pipe 402, so that the operation panel 103 displays the real-time temperature respectively. The temperature of the water in the kettle 201, the pumping pipe 401 and the drain pipe 402 is shown, and the temperature of the water in the pumping pipe 401 and / or the drain pipe 402 is controlled between 40-50°, which is the optimal water temperature range for brewing milk powder. When the water pump 3 is started again to pump out the water, the water temperature in the kettle 201 will not change after mixing with the previously stagnant water in the pumping pipe 401 and the drain pipe 402, thereby preventing the water from being too low in the pumping pipe 401 and the drain pipe 402 for a long time, resulting in the overall water temperature after the constant temperature water is mixed with the water not meeting the optimal range for brewing milk powder, thereby preventing the water temperature from affecting the quality of the brewed milk powder.

[0031] Preferably, reference Figure 2 The heating element 5 is a flexible heating element, and its manufacturing material can be carbon fiber heating wire or silicone electric heating film. In actual use, the heating element 5 can be a carbon fiber heating wire wrapped around the water suction pipe 401 and / or the drainage pipe 402, or a silicone electric heating film can be used to wrap the water suction pipe 401 and / or the drainage pipe 402. The purpose is to allow the heating element 5 to change with the shape of the water suction pipe 401 and / or the drainage pipe 402 when the water suction pipe 401 and / or the drainage pipe 402 is a hose, so that the heating element 5 is always in contact with the water suction pipe 401 and / or the drainage pipe 402, thereby ensuring the heating effect.

[0032] Preferably, a water valve 202 connected to a water extraction pipe 401 is provided on the heating base 2, and the water valve 202 is composed of an internal ball valve and a push spring, and a water inlet connected to the water valve 202 is added to the heating part of the kettle 201. When the water pump 3 is started, the water extraction pipe 401 generates suction, so that the ball valve inside the water valve 202 moves, so that the inside of the kettle 201 can be extracted by the water extraction pipe 401, and when the water pump 3 stops working, the push spring inside the water valve 202 will push the ball valve to block the internal channel of the water valve 202.

[0033] Among them, in the utility model, the temperature sensor a6 and the temperature sensor b can be NTC temperature sensors, which are a kind of thermistor and probe. The temperature sensor a6 and the temperature sensor b are used to detect the water temperature of the kettle 201, the water pipe 401 and the drain pipe 402 respectively, so that the water temperature of the two places can be displayed in real time on the operation panel 103.

[0034] The probe of the temperature sensor a6 can contact the outer wall of the water suction pipe 401 and / or the drainage pipe 402 to detect the temperature of the water suction pipe 401 and / or the drainage pipe 402, so as to know the temperature of the water inside. The probe can also be extended to the inside of the water suction pipe 401 and / or the drainage pipe 402 to directly detect the water body, so that the temperature sensor a6 detects the temperature of the water and transmits the detection data to the operation panel 103, that is, the water temperature data is displayed on the operation panel 103, ensuring that the water temperatures at the two places are consistent, and ensuring that the water temperature when flowing out of the water outlet 101 is in the optimal water temperature range for brewing milk powder.

[0035] An operation panel 103 is provided on the outside of the main body 1, and the operation panel 103 contains control buttons and a water temperature display area. The control buttons on the operation panel 103 are used to send commands to the control chip, thereby controlling the start and stop of the heating element 5, the temperature sensor a6, the temperature sensor b, the solenoid valve 102, and the water pump 3. The water temperature display area displays the water temperature of the water flow inside the kettle 201 and the water suction pipe and / or the drainage pipe 402 in real time.

[0036] like Figure 1 As shown, a water filling area is formed on the main body 1, a groove is opened at the bottom of the water filling area, a water filling frame 7 is placed inside the groove, and the water filling area is provided with, the water filling area is located below the water outlet 101, and the water filling frame 7 is provided with a mesh plate, which is placed on the mesh plate for filling water.

[0037] When placed on the bottom plate to receive water, water flowing out of the water outlet 101 will inevitably drip onto the mesh plate, or when receiving water, the inside needs to be simply cleaned. The cleaned water can be poured on the mesh plate, and the water enters the water filling frame 7 through the mesh plate. By removing the water filling frame 7 from the groove, the sewage inside the water filling frame 7 can be cleaned out.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
