Description

Technical Field

[0001] The utility model relates to the field of oxygen pumps, in particular to an oxygen pump for supplying oxygen to an aquarium. Background Art

[0002] Aquarium oxygen pumps, also known as oxygen pumps, air pumps, and oxygen pumps, operate similarly to industrial oxygen pumps but generally require less power. They work by forcing air into water, allowing the oxygen in the air to fully contact the water and dissolve into the water, thereby increasing the dissolved oxygen content in the water to meet the growth needs of oxygen-consuming organisms. Oxygen pumps are widely used in modern fish farming due to their ease of use, efficiency, and low cost.

[0003] Existing oxygen pumps are mainly leather bowl type air pumps. Since the existing leather bowl type air pumps use the flexibility and deformation ability of the leather bowl to generate airflow by reducing the space inside the bowl when contracting and restoring the space inside the bowl when reducing, this high-frequency deformation will cause material fatigue. The leather bowl is the core of the entire air pump, so the service life of the entire air pump is limited by the leather bowl. Therefore, it is necessary to solve the problem of leather bowl strain affecting the life of the air pump.

[0004] The technical problems that need to be solved in this application are: how to slow down the fatigue of the pump body to extend its service life, and how to provide uniform airflow. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present invention aims to provide an air pump with a long service life and a large air volume.

[0006] The technical solution adopted by the utility model is as follows: an oxygen pump for supplying oxygen to an aquarium, comprising a base and a hollow cylinder, the hollow cylinder being provided with two air holes communicating with the interior thereof, a motor being provided in the base, a driving end of the motor being inserted into the hollow cylinder, a rotor being provided in the hollow cylinder and being assembled on the driving end of the motor, at least three inclined inner rail grooves being symmetrically provided on the rotor, sliding blades being inserted into the inner rail grooves, a cavity diameter of the hollow cylinder being smaller than the total length of the sliding blades and the inner rail grooves, the sliding blades being slidably mounted in the cavity of the hollow cylinder through the inner rail grooves, and the inner wall of the hollow cylinder and the sliding blades being both made of graphite.

[0007] In the utility model, the rotor is driven to rotate by a motor, and the rotor drives the sliding blades to rotate in the hollow cylinder body. Under the action of centrifugal force, the sliding blades slide out of the inner rail groove and fit into the hollow cylinder body, so as to better draw in air flow. The air flow flows into the hollow cylinder body through one of the air holes and is discharged outward from the hollow cylinder body through the other air hole, thereby completing the air pumping operation. In this process, since the side wall of the sliding blade fits into the inner wall of the hollow cylinder body and the upper and lower ends of the hollow cylinder body are relatively sealed, the suction force generated is stronger, so that the air flow continuously enters and exits the two air holes, and the space in the hollow cylinder body is compact, so the volume of the air flow temporarily stored in the hollow cylinder body is relatively small, so that the volume of the air flow discharged from the air hole is uniform and the output is dense.

[0008] In some embodiments, a gasket is provided between the top of the base and the bottom of the hollow cylinder, and the hollow cylinder and the gasket fit tightly together.

[0009] In some embodiments, a mounting foot for auxiliary fixation is provided on one side of the gasket, and the gasket is made of graphite.

[0010] In some embodiments, the air holes are an air inlet and an air outlet, the air inlet is connected to the outside of the aquarium through a pipe, and the air outlet is provided with a one-way valve for exhausting air into the aquarium.

[0011] In some embodiments, an air chamber is further provided on the top of the hollow cylinder, and the air holes are all connected to the air chamber.

[0012] In some embodiments, a plurality of grids are provided in the air chamber, the grids divide the air chamber into equal parts, and the outer wall edge structure of the grids is a curved structure.

[0013] The beneficial effects of the present invention are:

[0014] (1) In the present invention, a motor is provided to drive the rotor to rotate, and the rotor drives the sliding blades to rotate in the hollow cylinder body. Under the action of centrifugal force, the sliding blades slide out of the inner rail groove and fit into the hollow cylinder body, thereby better drawing in air flow.

[0015] (2) In the present invention, since the side wall of the sliding blade fits against the inner wall of the hollow cylinder body, and the upper and lower ends of the hollow cylinder body are relatively sealed, the suction force generated is stronger, so that the air flow continuously enters and exits the two air holes. Moreover, the space in the hollow cylinder body is compact, so the volume of the air flow temporarily stored in the hollow cylinder body is relatively small, so that the volume of the air flow discharged from the air hole is uniform and the output is dense.

[0016] (3) In the present invention, a gasket made of graphite material with a low friction coefficient and strong wear resistance is used to enable the rotor to rotate more smoothly and avoid the sliding blades in the pump body from rotating sluggishly. Compared with the existing leather cup type air pump, the vane pump has better durability and longer service life.

[0017] (4) In the utility model, oxygenation is performed by rotating the rotor to pump air. Compared with the existing leather cup type air pump, the service life is longer. The deformation process of the leather cup will cause the mechanical energy to attenuate. Therefore, under the same conditions, the air flow and air pressure generated by the rigid fan blades will be greater. It does not use high-frequency vibration to squeeze the air bag. Compared with the leather cup pump, the noise is smaller. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1 to 6The utility model provides a technical solution: an oxygen pump for supplying oxygen to an aquarium, comprising a base 1 and a hollow cylinder 2, the hollow cylinder 2 being provided with two air holes 3 communicating with the interior thereof, an air chamber 30 being further provided on the top of the hollow cylinder 2, the air holes 3 being all communicated with the air chamber 30, the air flow in the air chamber 30 being able to enter and exit the hollow cylinder 2 through the air holes 3, a plurality of grids 34 being provided in the air chamber 30, the grids 34 dividing the air chamber 30 evenly, and the outer wall edge structure of the grids 34 being a curved structure, the air flow passing through the curved edge When the grid 34 is opened, the size of the fluid will be further refined, thereby reducing the volume of the bubbles when discharged. The air holes 3 are respectively an air inlet 31 and an air outlet 32. The air inlet 31 is connected to the outside of the aquarium through a pipe, and the air outlet 32 ​​is provided with a one-way valve 33 for discharging air into the aquarium. When the bubbles with uniform volume and continuous density enter the aquarium, they can quickly and fully hydrolyze oxygen in the water in the aquarium. The rotor 20 is used to rotate and pump air for oxygenation, which has a longer service life than the existing leather bowl type air pump.

[0027] See also Figures 1 to 6 , a motor 10 is provided in the base 1, and the driving end of the motor 10 is inserted into the hollow cylinder body 2. The hollow cylinder body 2 is provided with a rotor 20 assembled on the driving end of the motor 10. The motor 10 drives the rotor 20 to rotate in the hollow cylinder body 2 so that it can pump air into the aquarium through the air holes 3. At least three inclined inner rail grooves 21 are symmetrically provided on the rotor 20, and sliding blades 22 are inserted in the inner rail grooves 21. The cavity diameter of the hollow cylinder body 2 is smaller than the total length of the sliding blades 22 and the inner rail grooves 21. The sliding blades 22 are slidably installed in the cavity of the hollow cylinder body 2 through the inner rail grooves 21. The rotor 20 drives the sliding blades 22 to rotate in the hollow cylinder body 2. Under the action of centrifugal force, the sliding blades 22 slide out in the inner rail grooves 21 and fit the inner wall of the hollow cylinder body 2, so the suction generated is stronger, so that the air flow continuously enters and exits the two air holes 3. The material of the inner wall of the hollow cylinder body 2 and the sliding blades 22 are both graphite.

[0028] See also Figures 1 to 6 A gasket 11 is provided between the top of the base 1 and the bottom of the hollow cylinder body 2. The hollow cylinder body 2 and the gasket 11 are tightly fitted together. One side of the gasket 11 is provided with an assembly foot 12 for auxiliary fixation. The material of the gasket 11 is graphite. The gasket 11 made of graphite has strong wear resistance and low friction coefficient, so that the rotor 20 can rotate more smoothly. The upper and lower ends of the hollow cylinder body 2 are relatively sealed, and the space inside the hollow cylinder body 2 is compact, so the volume of the airflow temporarily stored in the hollow cylinder body 2 is relatively small, so that the volume of the airflow discharged from the air hole 3 is uniform and the output is dense. The oxygen pump for oxygen supply to the aquarium can be fixed in the aquarium through the assembly foot 12.

[0029] The working principle and use process of the utility model are as follows: First, the oxygen pump for supplying oxygen to the aquarium is fixed to the bottom of the aquarium by means of the assembly foot 12. At this time, the air outlet 32 ​​of the two air holes 3 is located below the water surface, and the air inlet 31 is connected to the outside of the aquarium or above the water surface through a pipe;

[0030] Subsequently, when oxygenating the water in the aquarium, the motor 10 is started, and the motor 10 drives the rotor 20 to rotate in the hollow cylinder 2. At this time, the sliding vanes 22 are acted upon by the centrifugal force, slide out of the inner rail groove 21, and slide the side walls against the inner wall of the hollow cylinder 2, thereby drawing air from the outside of the aquarium or above the water surface into the air chamber 30 through the air inlet 31. As the rotor 20 rotates, the rotor 20 will have a certain contact with the gasket 11, so the gasket 11 is made of graphite with a low friction coefficient and strong wear resistance, so that the rotor 20 can rotate more smoothly and avoid the sliding vanes 22 in the pump body from rotating sluggishly.

[0031] Then, the airflow will first pass through the curved edge grid 34, which disperses and refines the airflow. The dispersed and refined airflow is discharged from the air chamber 30 through the air outlet 32 ​​and enters the water surface of the aquarium through the one-way valve 33. At this time, the airflow forms uniform, continuous and dense bubbles in the water, allowing the water in the aquarium to fully hydrolyze the bubbles and oxygenate the water.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
