Description

Technical Field

[0001] This utility model relates to a water pump, and more particularly to an overflow hole structure for the side of the water pump. Background Technology

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of a prime mover or other external energy to the liquid, increasing its energy. It is mainly used to transport liquids including water, oil, acids and alkalis, emulsions, suspensions, and liquid metals. It can also transport mixtures of liquids and gases, as well as liquids containing suspended solids. Technical parameters of water pump performance include flow rate, suction head, discharge head, shaft power, water power, and efficiency. Based on different working principles, they can be classified into positive displacement pumps, centrifugal pumps, etc. Positive displacement pumps utilize changes in the volume of their working chamber to transfer energy; centrifugal pumps utilize the interaction between rotating blades and water to transfer energy, and include centrifugal pumps, axial flow pumps, and mixed flow pumps. Traditional products have a simple overflow hole at the bottom, allowing water to flow out freely without guidance. When an internal fault occurs, water accumulates, affecting circuit safety. When the motor malfunctions, the circuit board fails, or the inlet water volume exceeds the overflow volume, water overflows from the entire pump surface, and the overflowing water cannot be collected, causing bubbles at the top. Utility Model Content

[0003] In view of the shortcomings of existing technology, this utility model provides an overflow hole structure for the side of a water pump.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an overflow hole structure for the side of a water pump, including a shell body, a water tank compartment inside the shell body, an overflow line at the upper part of the water tank compartment, and at least one snap-fit ​​water guiding component at the overflow line and around the water tank compartment.

[0005] The water guiding assembly includes a socket and a water guiding pipe that fit together.

[0006] The water tank compartment is provided with an installation groove for the card holder to engage. The side wall and bottom surface of the card holder are provided with a connected card groove. The wall of the installation groove engages with the card groove for limiting and fixing.

[0007] The water guide pipe is provided with a stop flange in the radial direction, and the stop flanges are arranged in pairs in the axial direction of the water guide pipe.

[0008] The water guide pipe is provided with a sealing ring at least between the stop flanges.

[0009] The card holder has an opening for the water pipe to pass through, and the stop flange is in contact with the card holder for limiting the movement.

[0010] The beneficial effects of this utility model are as follows: The overflow hole structure for the side of a water pump provided by this utility model is simple and ingenious. Since there are certain requirements for sealing, the snap-fit ​​sealing structure meets the design requirements. The overflow hole is designed on the side of the water pump (including the surrounding area) at a position lower than the edge of the water tank. When the motor does not work, the circuit board is broken, or the water inflow is greater than the overflow flow, the overflow will flow out through our overflow hole and be guided to the designated overflow position by the overflow pipe of the overflow hole.

[0013] Figure 3 This is an exploded structural diagram of the water guiding component of this utility model. Detailed Implementation

[0014] like Figures 1-3 As shown, an overflow hole structure for the side of a water pump includes a shell body 1, within which a water tank compartment is provided. The water tank compartment has an overflow line at its upper part, and at least one snap-fit ​​water guiding component 2 is provided at the overflow line and around the perimeter of the water tank compartment. The dedicated water guiding component 2 allows for timely overflow drainage, preventing excessive water accumulation and bubbling during malfunctions. The snap-fit ​​design already meets the relative sealing requirements, eliminating the need for higher precision. The drain pipe can also be integrated with the shell body 1 as needed; however, this will not be elaborated upon or limited here.

[0015] The water guiding assembly 2 includes a plug-in fitting seat 3 and a water guiding pipe 4, simplifying the connection structure. The direct plug-in design of the water guiding pipe 4 meets usage requirements. Furthermore, the water guiding pipe 4 is typically a rubber hose, providing anti-slip properties and a certain degree of elasticity. The water tank compartment is provided with an installation groove 5 for the seat 3 to engage. The side wall and bottom surface of the seat 3 are connected by a groove 6, and the groove wall of the installation groove 5 engages with the groove 6 for positioning and fixation. The engagement of the installation groove 5 and the groove 6 achieves a labyrinth seal, meaning the medium achieves throttling and sealing effects through a continuously tortuous channel. The water guiding pipe 4 has a stop flange 7 in the radial direction, and the stop flanges 7 are arranged in pairs in the axial direction of the water guiding pipe 4. The water guiding pipe 4 has a sealing ring at least between the stop flanges 7. Furthermore, the design of the stop flanges 7 and the sealing ring improves the connection sealing and anti-slip properties at this point. The seat 3 has an opening 8 for the water guiding pipe 4 to pass through, and the stop flange 7 engages with the seat 3 for positioning and fixation. In this embodiment, the stop flange 7 also serves as a labyrinth seal, further preventing the water pipe 4 from easily detaching. In specific manufacturing and design, the stop flange 7 can be of varying sizes or other structural combinations, depending on the actual application requirements.
