Description
Technical Field
[0001] The utility model relates to the technical field of micro water pumps, in particular to a micro water pump capable of draining water. Background Art
[0002] The micro pumps used in the existing thermostatic electric kettles and other household appliances on the market are mostly single-inlet and single-outlet pumping systems (i.e. one end is the liquid inlet and the other end is the liquid outlet). In conventional designs, in order to ensure that the water pump can effectively transport water to the water outlet tank and prevent water from flowing back into the pump tank when the water pump is turned off, a valve is usually added to the system, and a silicone sealing mechanism is used inside the valve.
[0003] However, this design also has certain defects. Since the water pump system adopts a unidirectional flow design, once the water pump stops working and the valve is closed, some water may remain in the outlet pipe. If this accumulated water cannot be discharged in time, the water quality may deteriorate if it is not used for a long time. Especially in the case of slight wear and tear on the inner wall of the pipe or aging of the material, the residual wastewater is more likely to react with the material, resulting in water pollution in the pipe.
[0004] Therefore, it is necessary to further improve and perfect the prior art to overcome these deficiencies, and the present invention is made based on this situation. Utility Model Content
[0005] The utility model aims to overcome the deficiencies of the prior art and provide a micro water pump which has a simple structure, can drain all the water in the water outlet pipe and is safer and more sanitary.
[0006] The utility model is realized by the following technical solutions:
[0007] In order to solve the above technical problems, the utility model provides a micro water pump that can drain water, including a shell, the shell is provided with a water inlet chamber, a water outlet chamber, and a pumping assembly for pumping water in the water inlet chamber to the water outlet chamber, the water inlet chamber is provided with a water inlet nozzle, the water outlet chamber is provided with a water outlet nozzle and a water drain nozzle connected thereto, and a valve assembly is provided at the water drain nozzle.
[0008] In order to further solve the technical problem to be solved by the utility model, the utility model provides a micro water pump that can drain water, wherein the water inlet nozzle is connected to a water inlet pipe, the water outlet nozzle is connected to a water outlet pipe, the drain nozzle is connected to a drain pipe, and the opening at the lower end of the drain pipe is lower than the opening at the upper end of the outlet pipe.
[0009] In order to further solve the technical problem to be solved by the utility model, the utility model provides a micro water pump capable of draining water, wherein the water pump is installed horizontally along the horizontal direction, and the drainage nozzle is lower than the water outlet nozzle.
[0010] In order to further solve the technical problem to be solved by the utility model, the utility model provides a micro water pump that can drain all the water, wherein the water outlet chamber is provided with a surrounding plate surrounding the water outlet nozzle and the drainage nozzle, and the inner side surface of the surrounding plate is provided with a drainage surface that guides the water at the bottom of the water outlet chamber to the drainage nozzle.
[0011] In order to further solve the technical problem to be solved by the utility model, the utility model provides a micro water pump capable of draining water, wherein the valve component is a solenoid valve.
[0012] In order to further solve the technical problem to be solved by the utility model, the utility model provides a micro water pump that can drain water, in which the pumping component includes a plurality of flexible capsule chambers arranged between a water inlet chamber and a water outlet chamber, a first one-way valve arranged between the water inlet chamber and the corresponding capsule chamber, a second one-way valve arranged between the corresponding capsule chamber and the water outlet chamber, and a driving component for intermittently compressing each capsule chamber.
[0013] In order to further solve the technical problem to be solved by the utility model, the utility model provides a micro water pump that can drain water, wherein the driving component includes a driving motor, and the output end of the driving motor is connected to an eccentric swing frame located on one side of each capsule chamber and capable of pressing each capsule chamber, and the driving motor drives the eccentric swing frame to swing eccentrically so as to compress each capsule chamber in turn.
[0014] In order to further solve the technical problem to be solved by the utility model, the utility model provides a micro water pump that can drain water, wherein the first one-way valve and the second one-way valve both include a valve seat, a valve hole arranged on the valve seat, and a valve sheet covering the valve hole and capable of being opened in one direction.
[0015] Compared with the prior art, the utility model has the following advantages:
[0016] 1. Unlike the traditional single-inlet and single-outlet pumping system, a key feature of the design of this micro water pump is the drain nozzle and the valve assembly on it. The drain nozzle is designed to be lower than the outlet nozzle, using gravity to assist the natural discharge of water, and the presence of the valve assembly ensures that the discharge of water can be controlled when needed. When the water pump starts to pump water normally, the valve assembly is closed and no water is discharged. After the water pump stops working, the valve assembly opens and completely drains the residual water in the outlet pipe through the drain nozzle, thereby avoiding the long-term retention of water in the system, which may cause health problems.
[0017] 2. In the utility model, the opening position of the lower end of the drain pipe is lower than the opening position of the upper end of the outlet pipe. This unique layout design further utilizes gravity to accelerate the water drainage process, ensuring that the system can remain dry when not in use and avoiding the growth of bacteria and mold. Even more cleverly, when the valve assembly is opened to allow water to be discharged through the drain nozzle, this drainage method does not rely solely on gravity. In fact, this process will also trigger the siphon phenomenon, which is a physical phenomenon that uses liquid continuity and atmospheric pressure differences to move liquids. Once the siphon action begins, it will continue to extract water from the outlet pipe, even if part of the water has been discharged by gravity. The introduction of this siphon action greatly enhances the efficiency and thoroughness of drainage, ensuring that the residual water in the outlet pipe can be more completely drained.
[0018] 3. In the utility model, the water pump is installed horizontally, the drain nozzle is cleverly set below the water outlet nozzle, and the drainage surface of the enclosure is specially designed to be inclined toward the drain nozzle, so that the water at the bottom of the water outlet cavity can be effectively guided to the drain nozzle. The subtlety of this design is that even after the pumping system stops working, the residual water in the water outlet cavity will not stay inside the cavity, but will be naturally guided to the drain nozzle, and the residual water will be discharged by utilizing gravity.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] like Figures 1 to 6The micro water pump shown here can effectively drain the water in the water outlet pipe through its unique design, thereby improving the safety and hygiene during use. The design includes a housing 1, a pumping assembly 2, a water inlet nozzle 3, a water outlet nozzle 4 and a drain nozzle 5, and a valve assembly 51 connected to the drain nozzle 5. The design of each component is intended to optimize the delivery and discharge of water.
[0028] The housing 1 is the main body of the water pump, and is divided into a water inlet chamber 11 and a water outlet chamber 12. The water inlet chamber 11 is introduced into the water source through the water inlet nozzle 3, and the water outlet chamber 12 is the flow area of the water after passing through the pumping component 2. The pumping component 2 is responsible for transporting the water in the water inlet chamber 11 to the water outlet chamber 12, and finally sending it out through the water outlet nozzle 4.
[0029] Different from the traditional single-inlet and single-outlet pumping system, a key feature in the design of the micro water pump is the drain nozzle 5 and the valve assembly 51 thereon.
[0030] In this design, the water pump is installed horizontally, and the drain nozzle 5 is cleverly arranged below the water outlet nozzle 4. Such a layout is very conducive to the gravity-assisted drainage process. Since the drain nozzle 5 is located lower than the water outlet nozzle 4, after the pumping system is turned off, the water in the water outlet cavity 12 can naturally flow to the drain nozzle 5 without the need for additional force to push, thereby achieving a fast and thorough self-draining function.
[0031] The drain nozzle 5 is designed to be lower than the outlet nozzle 4, and gravity is used to assist the natural discharge of water, while the presence of the valve assembly 51 ensures that the discharge of water can be controlled when necessary. When the water pump starts to pump water normally, the valve assembly 51 is closed and no water is discharged. After the water pump stops working, the valve assembly 51 opens and completely drains the residual water in the outlet pipe through the drain nozzle 5, thereby avoiding the long-term retention of water in the system, which may cause health problems.
[0032] It is worth noting that the water outlet nozzle 4 and the drain nozzle 5 are both connected to the water outlet chamber 12, that is, the drain nozzle 5 is connected to the water outlet nozzle 4 and the water outlet chamber 12. Therefore, when the valve assembly 51 is opened, not only the water in the water outlet pipe can be discharged, but also the residual water in the water outlet chamber 12 can be discharged. It ensures that the equipment can be completely emptied after completing the pumping task, thereby greatly reducing the growth space of bacteria and mold, extending the service life of the equipment, and reducing the workload of daily maintenance.
[0033] Further, such as Figure 6 As shown, the water outlet chamber 12 is provided with a surrounding plate 121 surrounding the water outlet nozzle 4 and the drain nozzle 5. The surrounding plate 121 surrounds the water outlet nozzle 4 and the drain nozzle 5, which not only guides the water flow, but also prevents water from leaking to other parts of the water pump.
[0034] The inner side surface of the enclosure 121 is provided with a drainage surface 122 for guiding the water at the bottom of the water outlet cavity 12 to the drain nozzle 5. The drainage surface 122 of the enclosure 121 is specially designed to be inclined toward the drain nozzle 5, so that the water at the bottom of the water outlet cavity 12 can be effectively guided to the drain nozzle 5. The subtlety of this design is that even after the pumping system stops working, the residual water in the water outlet cavity 12 will not stay inside the cavity, but will be naturally guided to the drain nozzle 5, and the residual water is discharged by utilizing gravity.
[0035] In addition, the opening position of the lower end of the drain pipe 52 is lower than the opening position of the upper end of the outlet pipe 41. This unique layout design further utilizes gravity to accelerate the water drainage process, ensuring that the system can remain dry when not in use and avoiding the growth of bacteria and mold.
[0036] Even more clever is that when the valve assembly 51 is opened to allow water to drain through the drain nozzle 5, this drainage method does not rely solely on gravity. In fact, this process also triggers the siphon phenomenon, which is a physical phenomenon that uses the continuity of liquid and atmospheric pressure differences to move liquid. Once the siphon action begins, it will continue to extract water from the outlet pipe 41, even if some of the water has been drained by gravity. The introduction of this siphon action greatly enhances the efficiency and thoroughness of drainage, ensuring that the residual water in the outlet pipe can be drained more completely.
[0037] Through the above structural combination, this micro water pump can not only efficiently complete the task of water transportation, but also completely drain the internal moisture after use, which significantly improves the hygiene during use.
[0038] In the design of this micro water pump, it is an optimal decision to design the valve assembly 51 as a solenoid valve. The use of the solenoid valve not only improves the automation and intelligence level of the entire system, but also brings great convenience and accuracy to the user's operation.
[0039] The solenoid valve can be opened or closed quickly by the control of an electrical signal. This fast response characteristic allows the drainage process to be controlled very accurately, even when residual water needs to be drained quickly to ensure a dry and hygienic system.
[0040] The design of the pumping assembly 2 ingeniously combines the flexible capsule chamber 21, the one-way valve and the driving assembly to form an efficient and reliable liquid delivery system. Inside the pumping assembly, a number of flexible capsule chambers 21 are provided between the water inlet chamber 11 and the water outlet chamber 12, and these capsule chambers are responsible for temporarily storing the liquid to be delivered. In order to achieve one-way flow of the liquid, a first one-way valve 22 is installed between the inlet end of each capsule chamber 21 and the water inlet chamber 11, and a second one-way valve 23 is installed between the outlet end and the water outlet chamber 12. This configuration ensures that the liquid can only flow from the water inlet chamber into the capsule chamber, and then from the capsule chamber into the water outlet chamber, effectively preventing the liquid from flowing back, thereby improving the pumping efficiency and the overall performance of the system.
[0041] The design of the drive assembly also reflects precision and efficiency. The assembly is centered on the drive motor 24, and its output end is connected to an eccentric swing frame 25, which is located on one side of each capsule chamber 21. The rotation of the drive motor 24 drives the eccentric swing frame 25 to eccentrically swing, and this swing compresses the capsule chamber 21 in turn through the top pressure. Whenever a capsule chamber is compressed, the liquid in the capsule chamber is forced into the water outlet cavity 12 through the second one-way valve 23, and at the same time, due to the release (i.e. rebound) of another capsule chamber, new liquid is filled into the released capsule chamber through the first one-way valve 22, and so on, to achieve continuous liquid delivery.
[0042] In the specific design of the one-way valve, the first one-way valve 22 and the second one-way valve 23 both adopt a structure including a valve seat 2a, a valve hole 2b and a valve plate 2c covering the valve hole 2b. The valve plate 2c can be opened in one direction to allow liquid to flow through the valve hole 2b, and in the opposite direction it is tightly attached to the valve hole 2b to prevent liquid from flowing back.
[0043] The material of the valve plate 2c is rubber. This is because rubber has good flexibility and sealing properties, can provide good sealing effect during the opening and closing process of the valve plate, and can also withstand repeated switching actions without being easily damaged, thereby improving the reliability of the one-way valve and the service life of the pumping component.
[0044] Through this design, the pumping assembly can achieve efficient and stable liquid delivery. The use of flexible capsule chambers increases the adaptability of the pumping system, which can handle liquids of different viscosities without clogging; the configuration of the one-way valve ensures the unidirectionality and continuity of liquid delivery, avoiding liquid backflow and leakage; the design of the electric drive and eccentric swing frame makes the pumping action more precise and efficient. Overall, the design of this pumping assembly is sophisticated and can meet the needs of liquid delivery in a variety of application scenarios.
