Description

A self-cleaning aquarium water pump Technical Field

[0001] This invention relates to the field of water pumps, and more particularly to an aquarium water pump with a self-cleaning function. Background Technology

[0002] In aquarium farming, aquarium pumps provide oxygen and create suitable water flow, promoting water circulation, increasing dissolved oxygen, and maintaining water quality. They are a core component for maintaining aquarium health. The pump uses centrifugal force to drive the impeller, drawing water in and pushing it to the outlet, creating a flow. This process promotes contact between the water and air, providing essential oxygen for fish. However, when the pump's suction is strong, some aquatic organisms may be drawn into the pump. To prevent this, a fine-mesh protective screen is typically installed at the pump's suction inlet. This effectively prevents large aquatic organisms from being sucked in. However, small aquatic organisms still risk passing through the screen and being sucked in. Replacing the screen with a finer mesh to prevent this would interfere with the pump's suction, severely affecting its normal operation. Summary of the Invention

[0003] To overcome the drawback that using a tightly meshed protective net to prevent small aquatic organisms from being sucked into the aquarium pump would affect the normal suction operation of the aquarium pump, this invention provides an aquarium pump with a self-cleaning function.

The system includes: a channel; a drain pipe rotatably connected inside the outer casing; a suction pipe rotatably connected to the drain pipe; a sleeve shaft rotatably connected to the suction pipe; an impeller fixedly connected to the sleeve shaft; a submersible motor installed inside the outer casing; a first drive gear and a second drive gear sequentially fixed to the output shaft of the submersible motor; a first transmission gear fixedly connected to the sleeve shaft; a second transmission gear fixedly connected to the drain pipe; a central shaft rotatably connected inside the suction pipe; a sleeve shaft fixedly connected to the central shaft; a spiral vane aligned with the inside of the suction pipe fixedly connected to the central shaft; a pumping blade aligned with the inside of the sleeve shaft fixedly connected to the central shaft; and an anti-collision frame protecting the outside of the pumping blade fixedly connected to the central shaft.

[0005] As a preferred embodiment of the present invention, all the pumping channels of the pumping pipe are configured as an inclined structure from the shaft center toward the side of the inlet channel closer to the impeller.

[0006] As a preferred embodiment of the present invention, a plurality of cleaning bristles are fixedly attached to the outer surface of the spiral blade and closely adhere to the inner wall of the liquid extraction tube.

[0007] As a preferred embodiment of the present invention, a plurality of cushioning fibers are fixedly attached to the outer surface of the anti-collision frame.

[0008] As a preferred embodiment of the present invention, a plurality of mounting rods are fixedly connected to the impeller; a moving blade is fixedly connected to one end of the mounting rod located in the liquid inlet channel.

[0009] As a preferred embodiment of the present invention, a plurality of fixed blades that cooperate with the moving blades are fixedly connected in the liquid inlet channel of the pump casing.

[0010] As a preferred embodiment of the present invention, a rotating ring is rotatably connected to the liquid extraction tube; the mounting rod is fixed to the rotating ring, and the rotating ring provides support for the portion of the mounting rod that extends into the liquid inlet channel.

[0011] As a preferred embodiment of the present invention, the inlet end of the liquid extraction tube is connected to several fixing rods; a baffle is fixedly connected to the fixing rod, and the baffle is configured to be inclined from the axis of the inlet end of the liquid extraction tube toward the pump casing.

[0013] As a preferred embodiment of the present invention, the baffle is made of a cushioning rubber material.

[0014] Compared with the prior art, the present invention has the following advantages: The aquarium water pump of the present invention with self-cleaning function is mainly composed of a pump casing, an impeller, and a suction pipe that connects to the liquid inlet channel of the impeller. The suction pipe has several suction channels along the axial direction. When the impeller pumps water through the suction channels in the suction pipe, the aquatic organisms in the water flow will flow along the suction pipe, so there is no need to worry about the aquatic organisms being sucked away by the impeller. At the same time, the extended suction pipe has multiple suction channels along the axial direction, which can deliver sufficient water flow to the impeller. During this process, the spiral vane and the pumping blade can automatically clean the aquatic organisms stuck in the suction pipe.

The aquarium water pump of the present invention with self-cleaning function solves the technical problem that using a tightly meshed protective net will affect the normal suction operation of the aquarium water pump in order to avoid small aquatic organisms being sucked into the aquarium water pump.

Impeller 3 is fixedly connected; a submersible motor 51 is installed inside the outer casing 1; the output shaft of the submersible motor 51 is sequentially fixedly connected to a first drive gear 52 and a second drive gear 54; a first transmission gear 53 is fixedly connected to the sleeve shaft 43, and the diameter of the first transmission gear 53 is larger than the diameter of the first drive gear 52; a second transmission gear 55 is fixedly connected to the drain pipe 42, and the diameter of the second transmission gear 55 is larger than the diameter of the second drive gear 54; the tooth ratio of the second transmission gear 55 to the second drive gear 54 is greater than the tooth ratio of the first transmission gear 53 to the first drive gear 52; the liquid extraction pipe 41 rotates... A central shaft 61 is movably connected; a sleeve shaft 43 is fixedly connected to the central shaft 61; a spiral blade 62 is fixedly connected to the central shaft 61, and the spiral blade 62 is located inside the liquid extraction tube 41; several cleaning bristles 63 that are tightly attached to the inner wall of the liquid extraction tube 41 are fixedly connected to the outer surface of the spiral blade 62; a water pumping blade 64 is fixedly connected to the central shaft 61, and the water pumping blade 64 is located inside the liquid discharge tube 42; a collision protection frame 65 is fixedly connected to the central shaft 61, and the collision protection frame 65 is sleeved on the outside of the water pumping blade 64 to prevent aquatic organisms from swimming towards the water pumping blade 64 and causing damage; several cushioning bristles 66 are fixedly connected to the outer surface of the collision protection frame 65.

[0019] The working steps of an aquarium water pump with self-cleaning function according to the present invention are as follows.

[0020] After both the outer casing 1 and the pump casing 2 are submerged in water, the submersible motor 51 is connected to an external power supply. The submersible motor 51 synchronously drives the first drive gear 52 and the second drive gear 54 to rotate. The first drive gear 52 meshes with the first transmission gear 53 to drive the sleeve shaft 43 to rotate rapidly. The sleeve shaft 43 drives the impeller 3 to continuously perform suction work in the pump casing 2. External water flow is drawn into the impeller 3 through the suction channel 4101 of the suction pipe 41 and the inlet channel 201 of the pump casing 2. Then, the impeller 3 continuously discharges the water flow through the outlet channel 202 of the pump casing 2. Since the suction pipe 41 has a large number of suction channels 4101 along the axial direction, the suction pipe 41, which is extended along the axial direction, can deliver enough water flow to the impeller 3 through the large number of suction channels 4101, so as to realize continuous water suction work in the water.

[0021] As the impeller 3 continuously draws water into the suction pipe 41, aquatic organisms entering the suction pipe 41 with the water flow cannot pass through the suction channel 4101 into the inlet channel 201. Therefore, there is no need to worry about aquatic organisms being drawn into the impeller 3. During this period, the second drive gear 54 meshes with the second transmission gear 55, driving the drain pipe 42 and the central shaft 61 to rotate. Since the gear ratio of the second transmission gear 55 to the second drive gear 54 is greater than the gear ratio of the first transmission gear 53 to the first drive gear 52, the transmission ratio of the second transmission gear 55 to the second drive gear 54 is less than the transmission ratio of the first transmission gear 53 to the first drive gear 52. Therefore, the rotation speed of the drain pipe 42 and the central shaft 61 will be less than the rotation speed of the impeller 3. The central shaft 61 drives the spiral vane 62 and the cleaning bristles 63 to rotate within the suction pipe 41. The continuously rotating spiral... The lever 62 pushes the aquatic organisms stuck in the suction pipe 41 towards the discharge pipe 42, thus automatically cleaning the aquatic organisms stuck in the suction pipe 41. At the same time, the cleaning bristles 63 rotating close to the inner wall of the suction pipe 41 can clean the mud and sand adhering to the inner wall. Meanwhile, the central shaft 61 drives the water pumping blade 64 to rotate in the discharge pipe 42. The water pumping blade 64 forms a discharge water flow from the suction pipe 41 to the discharge pipe 42 in the discharge pipe 42, preventing the external water flow from flowing back into the suction pipe 41 through the discharge pipe 42 under the suction of the impeller 3. Therefore, the aquatic organisms in the discharge pipe 42 can flow out smoothly under the push of the discharge water flow. When the aquatic organisms are too small to swim flexibly in the discharge water flow, they will collide with the anti-collision frame 65 under the push of the discharge water flow. At this time, the cushioning bristles 66 can reduce the impact of the collision.

[0022] Example 2, as shown in Figures 1-8, is based on Example 1. In this example, the impeller 3 is fixedly connected to several mounting rods 31. Each mounting rod 31 has a movable blade 32 fixedly connected to one end in the inlet channel 201. Several fixed blades 21, which cooperate with the movable blades 32 for shearing, are fixedly connected to the inlet channel 201 of the pump housing 2. A rotating ring 33 is rotatably connected to the suction pipe 41. The rotating ring 33 is fixedly connected to one end of all mounting rods 31 in the inlet channel 201, and the rotating ring 33 extends into the inlet channel 201 opposite to the mounting rod 31. Part 01 provides support; when the impeller 3 continuously draws external water into the liquid inlet channel 201, the water will carry small-volume debris such as mud and sand through the liquid extraction channel 4101 and enter the liquid inlet channel 201. When the debris such as mud and sand passes between the moving blade 32 and the fixed blade 21 with the water flow, the impeller 3 drives the mounting rod 31 and its connected moving blade 32 and rotating ring 33 to rotate rapidly. The rapidly rotating moving blade 32, together with the stationary fixed blade 21, cuts the debris such as mud and sand into a pulverized state, reducing the collision and wear inside the impeller 3.

[0023] Example 3, as shown in Figures 1-8, is based on Example 2. In this example, the inlet end of the suction pipe 41 is connected to six fixed rods 71. Each of the six fixed rods 71 ​​is fixedly connected to a baffle 72, which is designed to be inclined from the axis of the inlet end of the suction pipe 41 towards the pump housing 2. All six fixed rods 71 ​​are slidably connected to the suction pipe 41. A compression spring 73 is fixedly connected between each of the six fixed rods 71 ​​and the suction pipe 41. The baffles 72 are all made of cushioning rubber material. When aquatic organisms are carried by the water flow towards the suction pipe 41... During directional suction, the baffle 72 made of buffer rubber material can reduce the collision with aquatic organisms. At the same time, when aquatic organisms collide violently with the baffle 72, the aquatic organisms push the baffle 72 to drive the compression spring 73 on the fixed rod 71 to compress, which can further reduce the collision between aquatic organisms and the baffle 72. When the aquatic organisms are large, the large aquatic organisms cannot pass through the gap between the adjacent baffles 72 to enter the suction pipe 41, and the large aquatic organisms will swim away from the pump casing 2 along the inclined structure of the baffle 72.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
