Description

Technical Field

[0001] The utility model relates to the technical field of fish tank water pumps, in particular to a fish tank water pump. Background Technique

[0002] The fish tank water pump promotes water flow through the rotation of the impeller, making the water body flow evenly to prevent the water body from standing still, thereby avoiding water quality deterioration and the accumulation of harmful substances. Secondly, through the agitation of the water flow, the dissolved oxygen content in the water can be increased, providing sufficient oxygen for the fish and other aquatic organisms in the fish tank to help them breathe.

[0003] However, traditional water pumps are composed of structures such as motors, impellers, and power cords. The motor drives the impeller to rotate, driving the impeller to rotate around its axis to drive the water flow to flow evenly and achieve functions such as pumping water, filtering, and aerating. The motor is electrically connected to the power cord. Traditional fish tank water pumps need to place the power cord connected to the external mains electricity and the water pump in the water of the fish tank together. Even if waterproof treatment is carried out at the connection between the power cord and the water pump, in the case of long-term immersion use, the power cord is prone to aging, and the aging power cord is extremely likely to be damaged and then cause electric leakage. Once electric leakage occurs, the fish in the fish tank will die due to electric shock. Secondly, during the process of changing the water in the fish tank, once the human body touches the water in the fish tank, there will be an electric shock risk, resulting in an electric shock accident.

[0004] Secondly, for some marine fish, it is necessary to ensure that the salt content of the water reaches a certain proportion. When the power cord is in water with a relatively high salt content for a long time, it will exacerbate the corrosion and aging of the power cord, resulting in an extremely high risk of electric leakage of the power cord. At the same time, the direct extension of the power cord into the water affects the ornamental value of the fish tank.

[0005] A Chinese patent discloses a small wireless water pump with a patent number of CN213808123U, which uses a wireless power supply method to supply power to the water pump to achieve wireless power supply and solve the problem that wired power supply affects the ornamental value. However, for the wireless power supply method, the power of the wireless power supply cannot reach the power of the traditional wired power transmission, resulting in the inability to reach the power of the water pump.

[0006] Secondly, an electromagnetic induction coil is set to control the opening and closing of the water pump. During use, the receiving end of the induction coil is still in the water, resulting in a complex waterproof process. It is prone to leakage and an increase in the failure rate after long-term use. In addition, wireless power induction transmission is restricted by distance. The thickness of the fish tank ranges from 3mm to 20mm, and the extremely large transmission uncertainty leads to problems such as abnormal operation and power consumption, etc., affecting the use of the fish tank.

[0061] Please refer to Figures 1 - 8 , an embodiment of the present utility model provides a fish tank water pump 100, and the fish tank water pump 100 includes:

[0062] A driving assembly 110, including a driving member 111 and a driving magnetic member 112 provided on the driving member 111, and the driving assembly 110 is provided outside the fish tank;

[0063] A rotating assembly 120, including a rotating member 121 and a rotating magnetic member 122 provided on the rotating member 121, the rotating assembly 120 is provided inside the fish tank, and the driving magnetic member 112 is coupled with the rotating magnetic member 122 so that the rotating magnetic member 122 receives the magnetic field of the driving magnetic member 112;

[0064] Wherein, the driving member 111 drives the driving magnetic member 112 to rotate to change the pole position of the driving magnetic member 112, so as to drive the rotating magnetic member 122 to rotate, and drive the rotating member 121 to rotate.

[0065] In this embodiment, the driving member 111 (such as a motor) is powered on and starts to rotate, driving the driving magnetic member 112 mounted thereon to rotate.

[0066] The driving magnetic member 112 begins to generate a dynamically changing magnetic field.

[0067] The magnetic field of the driving magnetic member 112 passes through the wall of the fish tank and acts on the rotating magnetic member 122 inside the fish tank.

[0068] The rotating magnetic member 122 starts to rotate after receiving the magnetic field of the driving magnetic member 112.

[0069] When the rotating magnetic member 122 rotates, it drives the rotating member 121 (such as an impeller) to rotate together.

[0070] The rotation of the rotating member 121 causes the flow of water, thus realizing the function of the water pump.

[0071] By transmitting power through the magnetic coupling method, the risk of direct contact between the power cord and water is eliminated, the possibility of electric leakage is avoided, and the safety of using the fish tank is improved.

[0072] Especially in a seawater environment with a relatively high salt content, the risk of corrosion and aging of the power cord is reduced.

[0073] Since the rotating assembly 120 is driven by the change of the magnetic field and the rotating assembly 120 is arranged in the liquid inside the fish tank, the rotating assembly 120 does not need to be connected to the power cord and can be rotated by the magnetic force of the driving assembly 110, avoiding the occurrence of electric leakage.

[0074] The driving component 110 and the rotating component 120 are respectively arranged on the outer side and the inner side of the fish tank, which is convenient for installation and maintenance.

[0075] When maintenance or replacement of the water pump is required, only the external driving component 110 needs to be processed, reducing the interference to the interior of the fish tank.

[0076] It should be noted that the driving member 111 is a motor, such as: a brushless motor, a variable-frequency motor, etc. In this embodiment, a variable-frequency motor is adopted.

[0077] The driving magnetic member 112 is a magnet, such as: a bipolar magnet (using the radial magnetization method), a multi-pole magnet (using the axial multi-pole magnetization, internal multi-pole magnetization, external multi-pole magnetization or oblique-angle magnetization methods). In this embodiment, a multi-pole magnet is adopted, and the shape of the multi-pole magnet is generally an annular magnetic ring.

[0078] The rotating member 121 is designed with an impeller on one side and a cylindrical ring on the other side, and the rotating member 121 is made of ceramic material. Since it is made of ceramic material, it can prevent the rotating member 121 from being corroded by the liquid with a high salt content during use.

[0079] The rotating magnetic member 122 is a magnet, such as: a bipolar magnet (using the radial magnetization method), a multi-pole magnet (using the axial multi-pole magnetization, internal multi-pole magnetization, external multi-pole magnetization or oblique-angle magnetization methods). In this embodiment, a multi-pole magnet is adopted, and the shape of the multi-pole magnet is generally an annular magnetic ring. The multi-pole magnet is obtained by dividing a complete magnet through sectional magnetization.

[0080] It should be further noted that when installing the driving component 110 and the rotating component 120, the driving component 110 is attached to the outer side of the fish tank, and the rotating component 120 is attached to the inner side of the fish tank. The driving magnetic member 112 and the rotating magnetic member 122 are attracted to each other to install the driving component 110 and the rotating component 120 on both sides of the fish tank glass, and there is no need to use screws or adhesives to fix the fish tank water pump 100.

[0081] The driving magnetic member 112 and the rotating magnetic member 122 are coaxial and parallel.

[0082] In other embodiments, two bar magnets can also be used, such as bar magnets with different polarities at both ends.

[0083] In at least one embodiment of the present application, the driving magnetic member 112 and the rotating magnetic member 122 are located on the same axis, and the driving magnetic member 112 and the rotating magnetic member 122 are parallel.

[0084] Please refer to Figures 1 - 8, in this embodiment, after the driving member 111 is powered on, it starts to rotate and drives the driving magnetic member 112 to rotate together.

[0085] Since the driving magnetic member 112 and the rotating magnetic member 122 are coaxially arranged, the magnetic field generated by the driving magnetic member 112 will act on the rotating magnetic member 122 along the same axis.

[0086] The rotation of the driving magnetic member 112 generates a magnetic field that varies along the same axis.

[0087] The rotating magnetic member 122 receives this coaxial magnetic field and generates a corresponding rotational movement.

[0088] The rotation of the rotating magnetic member 122 drives the rotating member 121 to rotate.

[0089] The rotation of the impeller causes the flow of water, realizing the function of the fish tank water pump 100.

[0090] The coaxial and parallel arrangement of the driving magnetic member 112 and the rotating magnetic member 122 ensures the high efficiency of magnetic field transmission and reduces magnetic field loss.

[0091] The coaxial and parallel arrangement of the driving magnetic member 112 and the rotating magnetic member 122 reduces unnecessary axial and radial vibrations, makes the rotation more stable, reduces offset and friction, reduces mechanical wear, and improves the durability of the system.

[0092] After the driving member 111 is powered on, it starts to rotate and drives the driving magnetic member 112 to rotate together.

[0093] Since the driving magnetic member 112 and the rotating magnetic member 122 are located on the same axis and are parallelly arranged, the magnetic field generated by the driving magnetic member 112 is transmitted along the axis to the rotating magnetic member 122.

[0094] The rotating magnetic member 122 receives this magnetic field and generates a corresponding rotational movement. Due to the parallel arrangement of the driving magnetic member 112 and the rotating magnetic member 122, the transmission efficiency of the magnetic field is higher and the acting force is more uniform.

[0095] The rotation of the rotating magnetic member 122 drives the rotating member 121 to rotate.

[0096] The rotation of the impeller causes the flow of water, thereby realizing the function of the fish tank water pump 100.

[0097] In at least one embodiment of the present application, the rotating magnetic member 122 is located on a side of the rotating member 121 close to the rotating assembly 120.

[0098] Please refer to Figures 1 - 8, in this embodiment, since the rotating magnetic member 122 is disposed close to the rotating assembly 120, the magnetic field transmission path is shortened, energy loss is reduced, transmission efficiency is improved, the magnetic field action is more concentrated, which helps the rotating magnetic member 122 receive the magnetic field more effectively and convert it into rotational motion.

[0099] In at least one embodiment of the present application, the rotating member 121 includes a rotating portion 1211 and an impeller portion 1212 disposed on one side of the rotating portion 1211. An accommodation groove 1211a is formed on a side of the rotating portion 1211 away from the impeller portion 1212, and the rotating magnetic member 122 is disposed in the accommodation groove 1211a.

[0100] In at least one embodiment of the present application, the rotating member 121 is provided with a mounting hole 121a;

[0101] The rotating assembly 120 further includes:

[0102] A first housing 123 having an accommodation cavity 123a formed therein, and the rotating portion 1211 is disposed in the accommodation cavity 123a;

[0103] A mounting shaft 124, one end of which is fixed in the accommodation cavity 123a, and the other end extends outside the accommodation cavity 123a through the mounting hole 121a.

[0104] Please refer to Figures 1 - 8 , in this embodiment, the driving member 111 rotates, thereby driving the driving magnetic member 112 to rotate, so that a rotating magnetic field generated by the driving magnetic member 112 is transmitted to the rotating magnetic member 122.

[0105] Since the rotating magnetic member 122 is located in the accommodation groove 1211a of the rotating member 121, it can directly receive the magnetic field of the driving magnetic member 112 and generate corresponding rotational power.

[0106] The rotational power of the rotating magnetic member 122 is transmitted to the impeller portion 1212 through the rotating portion 1211, driving the impeller portion 1212 to start rotating.

[0107] The rotation of the impeller portion 1212 generates water flow, realizing the function of the water pump, that is, pushing the water body to flow, thereby increasing the oxygen content of the water and purifying the water quality.

[0108] Placing the rotating magnetic member 122 in the accommodation groove 1211a can protect the magnetic member from physical damage and ensure its stable operation, thereby improving the efficiency and reliability of the entire system.

[0109] The mounting shaft 124 ensures the coaxiality of the rotating portion 1211 and the impeller portion 1212, ensuring the high efficiency of power transmission and reducing energy loss.

[0110] It should be noted that the first housing 123 is a sunken rectangular housing, and the accommodation cavity 123a is a cylindrical cavity formed by inward depression on the side of the first housing 123 away from the drive assembly 110.

[0111] The rotating part 1211 is generally a circular plate. An annular accommodation groove 1211a is formed by inward depression on the side of the rotating part 1211 close to the drive assembly 110. The accommodation groove 1211a is an annular groove, and the mounting hole 121a is opened at the geometric center position of the rotating part 1211, and the mounting hole 121a is a circular through hole.

[0112] The mounting shaft 124 is a cylindrical shaft and is made of ceramic material. The pressure surface of the impeller part 1212 is made of a circular ceramic material to play a role in anti-wear and lubrication. Secondly, it prevents the corrosion of seawater.

[0113] The impeller part 1212 is generally composed of a plurality of fan blades and is arranged perpendicular to the end face of the rotating part 1211.

[0114] In at least one embodiment of the present application, a water outlet 123a is provided on the first housing 123;

[0115] The rotating assembly 120 further includes:

[0116] An inlet cover 125 is provided with an inlet 125a. The inlet cover 125 is arranged in the accommodation cavity 123a and partially shields the accommodation cavity 123a. The inlet 125a is communicated with the accommodation cavity 123a, and the accommodation cavity 123a is communicated with the water outlet 123a.

[0117] In at least one embodiment of the present application, the rotating assembly 120 further includes:

[0118] A lubricating member 126 is located between the rotating member 121 and the inlet cover 125. One end of the mounting shaft 124 is arranged on the first housing 123, and the other end sequentially passes through the rotating member 121 and the lubricating member 126 and is fixedly connected to the inlet cover 125.

[0119] Please refer to Figures 1 - 8 , in this embodiment, when the water pump is started, the drive assembly 110 causes the rotating magnetic member 122 to rotate through the magnetic field effect, thereby driving the rotating member 121 to rotate.

[0120] The rotating impeller part 1212 pushes the water to enter the accommodation cavity 123a from the inlet 125a through the inlet cover 125, and then discharges it through the water outlet 123a.

[0121] The inlet cover 125 makes the water flow entering the accommodation cavity 123a more uniform, reduces eddy currents and water flow dead ends, and improves the efficiency of the water pump.

[0122] The lubricating member 126 reduces the direct contact between the rotating member 121 and the water inlet cover 125, reduces the friction and noise during operation, and improves the durability and stability of the entire system.

[0123] It should be noted that the water inlet cover 125 is provided with a plurality of water inlets 125a along the axial direction. The shape of the water inlet cover 125 is substantially the same as the shape of the accommodating cavity 123a and is used to cover the accommodating cavity 123a.

[0124] The lubricating member 126 is a circular ring member and is made of ceramic material, which is used to prevent wear caused by the direct contact between the impeller part 1212 and the water inlet cover 125.

[0125] The water outlet 123a is provided at the top of the first housing 123.

[0126] In at least one embodiment of the present application, the rotating assembly 120 further includes:

[0127] A filter net cover 127, which is covered on the first housing 123 and partially covers the accommodating cavity 123a. A dirt suction port 127a is provided on the side of the filter net cover 127 away from the water outlet 123a, and the dirt suction port 127a communicates with the accommodating cavity 123a;

[0128] A first magnetic member 128 is provided on the side of the filter net cover 127 close to the first housing 123;

[0129] A second magnetic member is provided on the first housing 123. The first magnetic member 128 is attracted to the second magnetic member to fix the filter net cover 127 on the first housing 123.

[0130] Please refer to Figures 1 - 8 , in this embodiment, water is pre-cleaned through the filter net cover 127, large particles and impurities are blocked outside, and the clean water flow enters the accommodating cavity 123a, is accelerated by the impeller part 1212, and finally discharged from the water outlet 123a.

[0131] Due to the first magnetic member 128 and the second magnetic member, the user can easily remove the filter net cover 127 from the first housing 123 for cleaning or replacement, and then attract and fix it again.

[0132] The filter net cover 127 effectively blocks impurities, protects the internal mechanical components of the water pump from damage, and improves the durability and reliability of the water pump.

[0133] Pre-clearing large particle impurities avoids clogging of the impeller and other sensitive components, thus maintaining the efficient operation of the water pump.

[0134] Secondly, by adjusting the rotation frequency of the rotating member 121, the sediment at the bottom of the fish tank can be discharged through the sewage suction port 127a at the bottom of the filter screen cover 127 via the water outlet 123a, so as to clean the bottom of the fish tank, maintain the cleanliness of the water body, and provide a healthier living environment for aquatic organisms.

[0135] It should be noted that the filter screen cover 127 is generally rectangular and meshed, and a sewage suction port 127a is formed at the bottom, and the sewage suction port 127a is a through port.

[0136] Both the first magnetic member 128 and the second magnetic member are magnets.

[0137] In at least one embodiment of the present application, the drive assembly 110 includes:

[0138] A second housing 113, with an installation cavity 113a formed inside. The drive member 111 and the drive magnetic member 112 are arranged in the installation cavity 113a. The drive magnetic member 112 is arranged at the output end of the drive member 111 and is located on one side close to the rotating magnetic member 122.

[0139] Please refer to Figures 1 - 8 , in this embodiment, when the power supply starts the drive member 111, the drive member 111 starts to rotate, and then drives the drive magnetic member 112 attached to its output end.

[0140] The drive magnetic member 112 generates a strong magnetic field. Since its position is close to the rotating magnetic member 122, the magnetic field directly acts on the rotating magnetic member 122.

[0141] The magnetic field of the drive magnetic member 112 is transmitted to the rotating magnetic member 122. Due to the short distance between the two, the transmission efficiency of the magnetic field is high and the energy loss is low.

[0142] After receiving the magnetic field, the rotating magnetic member 122 starts to rotate, driving the rotating member 121 connected thereto to rotate, thereby pushing the water flow.

[0143] It should be noted that the drive magnetic member 112 is fixed to the output end of the drive member 111 by pasting, and an installation disk is provided at the output end of the drive member 111. The drive magnetic member 112 is installed on the drive member 111 through the installation disk.

[0144] The rotating magnetic member 122 is fixed in the accommodation groove 1211a by pasting.

[0145] The second housing 113 is a rectangular housing, and the installation cavity 113a is a cavity formed inside the second housing 113.
