Description

Technical Field

[0001] The present invention relates to the technical field of small household appliances, and more specifically, to a water outlet pump assembly and its application. Background Art

[0002] Generally, electric thermos flasks have a relatively large capacity. When heating water, a large number of bubbles will be generated at the bottom inside before the water boils. During the process of the bubbles rising to the water surface, they will burst and generate relatively loud noises. Especially when used at night, the noise is more obvious, which affects the user experience of consumers. To solve this problem, there is a solution to set a stirring component inside the inner liner of the electric thermos flask. When boiling water, the water is stirred to destroy the bubbles before they are generated, so as to reduce the noise. For example, Chinese Patent CN203987631U discloses a liquid heating container, which includes a container body. The container body is provided with a containing cavity, and a stirring device is installed in the containing cavity. The stirring device can reduce the noise generated when the liquid heating container heats the liquid. However, in the above-mentioned solution, the stirring device is directly installed inside the inner liner of the electric thermos flask. Then, when it is necessary to clean the inside of the inner liner of the electric thermos flask, the stirring device will hinder the cleaning and bring inconvenience to the cleaning. Summary of the Invention

[0003] In order to overcome the defect that in the existing electric thermos flask, a stirring device is set inside the inner liner for noise reduction, and the stirring device brings inconvenience to the cleaning of the inside of the inner liner, the present invention provides a water outlet pump assembly and its application. The structure of the present invention is simple and easy to use, and it can achieve noise reduction without hindering the cleaning of the inner liner.

[0004] To solve the above technical problems, the technical solution adopted by the present invention is as follows: A water outlet pump assembly includes a water outlet pump body and a first motor connected to the water outlet pump body and used to drive the water outlet pump body. The water outlet pump body is provided with a water inlet pipe and a water outlet pipe. The water inlet pipe, the water outlet pump body, and the water outlet pipe form a water outlet channel. Among them, a second motor is provided at a position corresponding to the water inlet pipe on the water outlet pump body. A stirring rod is arranged in the water inlet pipe. The output shaft of the second motor extends into the water inlet pipe and is connected to one end of the stirring rod away from the water inlet of the water inlet pipe. The existing water outlet pump assembly only includes a water pump body and a first motor that drives the water pump to operate. The water pump body is provided with a water inlet pipe and a water outlet pipe; this application is equivalent to adding a stirring rod and a second motor that drives the stirring rod to rotate to the existing water outlet pump assembly, and the stirring rod is arranged inside the water inlet pipe of the water pump body. When the water outlet pump assembly is connected to an electric thermos flask, it is connected to the water outlet of the inner liner of the electric thermos flask through the water inlet pipe. The water outlet of the inner liner of the electric thermos flask is generally arranged on the bottom surface of the inner liner. In this way, when the electric thermos flask is boiling water, the second motor drives the stirring rod to rotate and stir the water in the water inlet pipe, and since the water inlet pipe is connected to the water outlet of the inner liner, it will also drive the water at the water outlet of the inner liner to rotate, thereby driving the water near the bottom surface of the inner liner to rotate. In this way, the water near the bottom surface of the inner liner is constantly rotating, so a large number of bubbles will not be generated on the bottom surface of the inner liner during the boiling process, greatly reducing the noise during boiling. In addition, since the stirring rod is in the water inlet pipe of the water pump body and not inside the inner liner, it will not interfere with the cleaning inside the inner liner.

[0005] Further, a stirring head is provided at the other end of the stirring rod. The stirring head can cause the water around it to generate a larger eddy current when the stirring rod rotates, so as to ensure that more water flows near the bottom surface of the inner liner can be driven to rotate, thereby destroying the bubbles generated on the bottom surface of the inner liner during boiling.

[0006] Further, both the first motor and the second motor are fixed to the water outlet pump body by screws.

[0007] The present invention also provides an electric thermos flask, which includes a bottle body. A heating component and the above-mentioned water outlet pump assembly are provided at the bottom of the bottle body. A water outlet is provided on the bottom surface of the bottle body. An outlet nozzle is provided on one side of the top of the bottle body. The water inlet of the water inlet pipe of the water outlet pump assembly is connected to the water outlet, and the water outlet pipe of the water outlet pump assembly is communicated with the outlet nozzle through a pipeline.

[0008] Further, a control component for controlling the heating component and the water outlet pump assembly is also provided inside the bottle body. A control panel connected to the control component is provided at a position corresponding to the outlet nozzle on the top of the bottle body. The entire working process of the electric thermos flask can be controlled through the control panel, which is convenient and practical.

[0009] Further, the heating component includes a heating plate, a heating tube disposed on one side surface of the heating plate, and a heat conduction plate cover covering the other opposite side surface of the heating plate. The side wall of the heat conduction plate cover is hermetically connected to the inner wall of the bottom end of the bottle body to form the bottom surface of the bottle body.

[0010] Further, the water outlet is provided on the top surface of the heat conduction plate cover. An outlet water filter is provided on the water outlet. The water inlet of the water inlet pipe of the water pump assembly is connected to the outlet water filter, and the stirring rod extends into the outlet water filter. The outlet water filter can prevent some impurities accidentally carried by the water from entering the water inlet pipe and the interior of the water pump body of the water pump main body, avoiding damage to the stirring rod and the water pump main body.

[0011] Further, a night vision lamp is provided on one side of the water outlet at the top of the bottle body. The night vision lamp can facilitate people to use the electric thermos flask at night.

[0012] Further, a cover body is provided on the top of the bottle body, and an air vent is provided on the cover body. A handle is further provided on the outer wall of the top of the bottle body.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] In the present invention, the stirring device is arranged in the water inlet pipe of the water pump cup body of the water pump assembly. When the water pump assembly is connected to the electric thermos flask, it is connected to the water outlet of the electric thermos flask through the water inlet pipe. Generally, the water outlet of the electric thermos flask is arranged on the bottom surface of the bottle body. In this way, when the electric thermos flask is boiling water, the second motor drives the stirring rod to rotate to stir the water in the water inlet pipe. Since the water inlet pipe is connected to the water outlet of the bottle body, it will also drive the water at the water outlet of the bottle body to rotate, and then drive the water near the bottom surface of the bottle body to rotate. In this way, the water near the bottom surface of the bottle body is always rotating, so a large number of bubbles will not be generated on the bottom surface of the bottle body during the boiling process, greatly reducing the noise during boiling. In addition, since the stirring rod is in the water inlet pipe of the water pump main body and not inside the bottle body, it will not interfere with the cleaning inside the bottle body.

[0023] Embodiment 1

[0024] As Figure 1 shown, a water outlet pump assembly includes a water outlet pump body 1 and a first motor 2 connected to the water outlet pump body 1 and used to drive the water outlet pump body 1. A water inlet pipe 3 and a water outlet pipe 4 are provided on the water outlet pump body 1. The water inlet pipe 3, the water outlet pump body 1 and the water outlet pipe 4 form a water outlet channel. Among them, a second motor 5 is provided at a position corresponding to the water inlet pipe 3 on the water outlet pump body 1. A stirring rod 6 is provided in the water inlet pipe 3. The output shaft of the second motor 5 extends into the water inlet pipe 3 and is connected to one end of the stirring rod 6 away from the water inlet of the water inlet pipe 3. The existing water outlet pump assembly only includes the water pump body 1 and the first motor 2 that drives the water pump to operate. A water inlet pipe 3 and a water outlet pipe 4 are provided on the water pump body 1; this application is equivalent to adding a stirring rod 6 and a second motor 5 that drives the stirring rod 6 to rotate on the existing water outlet pump assembly, and the stirring rod 6 is arranged inside the water inlet pipe 3 of the water pump body 1. When the water outlet pump assembly 11 is connected to the electric hot water bottle, it is connected to the water outlet 81 of the electric hot water bottle through the water inlet pipe 3. The water outlet 81 of the electric hot water bottle is generally arranged on the bottom surface of the bottle body 8. In this way, when the electric hot water bottle is boiling water, the second motor 5 drives the stirring rod 6 to rotate to stir the water in the water inlet pipe 3. Since the water inlet pipe 3 is connected to the water outlet 81 of the bottle body 8, the water at the water outlet 81 will also be driven to rotate, and then the water near the bottom surface of the bottle body 8 will be driven to rotate. In this way, the water near the bottom surface of the bottle body 8 is always rotating, so a large number of bubbles will not be generated on the bottom surface of the bottle body 8 during the boiling process, greatly reducing the noise during boiling. In addition, since the stirring rod 6 is in the water inlet pipe 3 of the water pump body 1 and not inside the bottle body 8, it will not prevent the cleaning inside the bottle body 8.

[0025] As Figure 1As shown, the other end of the stirring rod 6 is provided with a stirring head 7. The stirring head 7 can cause the water around it to generate a larger eddy current when the stirring rod 6 rotates, so as to ensure that more water flow near the bottom surface of the bottle body 8 can be driven to rotate, thereby destroying the bubbles generated on the bottom surface of the bottle body 8 during boiling.

[0026] In this embodiment, the first motor 2 and the second motor 5 are both fixed to the water pump body 1 by screws.

The entire working process of the electric water bottle can be controlled through the control panel 14, which is convenient and practical.

[0030] As Figure 5 and Figure 6 shown, the heating component 10 includes a heating plate 101, a heating tube 102 provided on one side surface of the heating plate 101, and a heat conduction plate cover 103 covering the other opposite side surface of the heating plate 101. The side wall of the heat conduction plate cover 103 is hermetically connected to the inner wall of the bottom end of the bottle body 8 to form the bottom surface of the bottle body 8.

[0031] As Figure 3 、 Figure 5 and Figure 6 shown, the outlet 81 is provided on the top surface of the heat conduction plate cover 103. An outlet filter nozzle 15 is provided on the outlet 81. The water inlet of the water inlet pipe 3 of the water pump assembly 11 is connected to the outlet filter nozzle 15, and the stirring rod 6 extends into the outlet filter nozzle 15.
