Description

Technical Field

[0001] This utility model relates to the field of coupler technology, and in particular to the water outlet of an automatic water-filling kettle coupler. Background Technology

[0002] As a core component of modern smart kettles, the automatic water-filling kettle coupler's spout performance directly impacts water filling efficiency and user experience. With increasing demands for intelligent drinking water equipment, the market is experiencing a surge in demand for automatic water-filling devices featuring leak-proof design, energy efficiency, and long lifespan. The spout, as a crucial component connecting the water pump and the kettle, not only needs to achieve rapid opening and closing and reliable sealing but also must consider low energy consumption and anti-clogging performance. This places higher demands on the spout's structural design.

[0003] In existing technologies, the outlet of automatic water filling devices mostly uses solenoid valves or purely mechanical check valves. Solenoid valves control the valve core movement via electrical signals to achieve on / off switching, requiring a dedicated drive circuit; while mechanical check valves primarily rely on water pressure differentials to drive the valve ball, using a spring for reset and sealing. Some improved designs incorporate flow guide grooves or buffer chambers inside the valve body to reduce water hammer. These structures typically use rubber sealing rings or O-rings for static sealing, ensuring a tight seal through a precise fit between the valve seat and the valve ball.

[0004] However, the existing mechanical check valve structure has a significant drawback: a high starting water pressure is required during the initial water injection stage to overcome the spring preload and open the valve ball. This not only increases the instantaneous load on the water pump, leading to increased energy consumption, but also easily causes poor sealing and leakage due to pressure fluctuations. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water outlet for an automatic water filling kettle coupler, which aims to improve the problem that the existing technology requires a higher starting water pressure in the initial water filling stage to overcome the energy consumption caused by the spring preload force pushing open the valve ball.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water outlet of an automatic water-filling kettle coupler, comprising a water inlet pipe, wherein a channel is provided inside the water inlet pipe, and an anti-clogging component is provided inside the water inlet pipe;

[0007] The anti-clogging component includes a sealing seat, which is disposed at one end of the water inlet pipe. A sealing ball is disposed above the sealing seat, and a spring is disposed above the sealing ball. One end of the spring is fixedly connected to the inner wall of the water outlet pipe. The water outlet pipe is fixedly connected to the outer wall of the sealing seat. A locking post is fixedly connected to the outer wall of the water inlet pipe. A push rod is fixedly connected to the outer wall of the water inlet pipe. Multiple water outlet holes are opened inside the water inlet pipe. An axial positioning block is fixedly connected to the outer wall of the water inlet pipe. A positioning strip is fixedly connected to the outer wall of the water inlet pipe. A limit seat is fixedly connected to the outer wall of the sealing seat.

[0008] Furthermore, the outer wall of the locking pin is slidably connected to the inner wall of the limiting seat.

[0009] Furthermore, the outer wall of the water inlet pipe is slidably connected to the inner wall of the limiting seat, and the sealing ball is attached to one end of the sealing seat.

[0010] Furthermore, the limiting seat has a sliding groove inside for the card column to slide.

[0011] Furthermore, multiple water outlet holes are arranged in a ring array inside the water inlet pipe.

[0012] Furthermore, the axis of the water outlet is at an angle of 30-60° to the central axis of the top rod.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, when installing the limiting seat, the push rod directly pushes the sealing ball upward to pre-compress the spring, forming an initial water flow channel. This avoids the problem of traditional structures requiring higher starting water pressure to open the sealing ball. When the kettle is picked up, the push rod automatically separates from the sealing ball. Combined with the air pressure balancing effect of the water outlet, the residual water pressure in the pipe can be eliminated immediately, achieving a leak-proof seal. This improves sealing reliability and reduces energy consumption. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 - Figure 3 The present invention provides an embodiment of an automatic water-filling kettle coupler, which includes an inlet pipe 1, an inlet channel 2 inside the inlet pipe 1, and an anti-clogging component inside the inlet pipe 1.

[0022] The anti-clogging component includes a sealing seat 4, which is located at one end of the water inlet pipe 1. A sealing ball 5 is positioned above the sealing seat 4, and a spring 6 is positioned above the sealing ball 5. One end of the spring 6 is fixedly connected to the inner wall of the water outlet pipe 7. The water outlet pipe 7 is fixedly connected to the outer wall of the sealing seat 4. A locking post 8 is fixedly connected to the outer wall of the water inlet pipe 1, and a push rod 11 is fixedly connected to the outer wall of the water inlet pipe 1. Multiple water outlet holes 10 are opened inside the water inlet pipe 1, and an axial positioning block 1 is fixedly connected to the outer wall of the water inlet pipe 1. 2. A positioning strip 9 is fixedly connected to the outer wall of the water inlet pipe 1. A limiting seat 3 is fixedly connected to the outer wall of the sealing seat 4. The outer wall of the locking post 8 is slidably connected to the inner wall of the limiting seat 3. The outer wall of the water inlet pipe 1 is slidably connected to the inner wall of the limiting seat 3. The sealing ball 5 is attached to one end of the sealing seat 4. A sliding groove for the locking post 8 to slide is opened inside the limiting seat 3. Multiple water outlet holes 10 are arranged in a ring array inside the water inlet pipe 1. The axis of the water outlet hole 10 forms an angle of 30-60° with the central axis of the top rod 11.

[0023] Specifically, firstly, the limiting seat 3 is assembled and connected to the water inlet pipe 1. One end of the water inlet pipe 1 is fixedly connected to the output end of the water pump. During installation, the push rod 11 fixed on the water inlet pipe 1 will push the sealing ball 5 upward, causing the sealing ball 5 to compress the spring 6. At this time, the water pump is started, and the water flows into the channel 2 of the water inlet pipe 1, flows through the water outlet 10 to the water outlet pipe 7, effectively reducing the air pressure resistance when the water flows through, significantly reducing the workload of the water pump, and thus extending the service life of the water pump. When the kettle is picked up, the sealing ball 5 and the push rod 11 automatically separate and quickly return to their original positions under the restoring force of the spring 6. At the same time, the presence of the water outlet 10 maintains the air pressure balance inside the water inlet pipe 1, effectively preventing the leakage of residual water.

[0024] Working principle: When the water outlet of this automatic water filling kettle coupler is needed, first, when adding water to the kettle, connect the limiting seat 3 to the water inlet pipe 1. One end of the water inlet pipe 1 is fixedly connected to the output end of the water pump. When installing the limiting seat 3, the push rod 11, which is fixedly connected to the water inlet pipe 1, can push the sealing ball 5 upward to compress the spring 6. At this time, the water pump is started, and the water flows into the water inlet pipe 1 and enters the water outlet pipe 7 through the water outlet hole 10, which reduces the air pressure and extends the service life of the water pump. When the kettle is picked up, the sealing ball 5 separates from the push rod 11. At this time, due to the presence of the water outlet hole 10, the air pressure inside the water inlet pipe 1 is relatively small, avoiding excess water leakage.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
