DETAILED DESCRIPTION

In description of the present embodiment, unless otherwise clearly specified and defined, terms such as “connected”, “connection” and “fixed” shall be understood in a broad sense, and for example, may refer to fixed connection or detachable connection or integral connection; may refer to mechanical connection or electrical connection; may refer to direct connection or indirect connection through an intermediary; and may refer to internal communication between two elements or interaction relationship between two elements. For those ordinary skilled in the art, specific meanings of the above terms in the present embodiment may be understood according to specific conditions.

As shown in FIG. 1 to FIG. 4, an aquarium in the present embodiment includes a tank body 1 and a water pump component 2. The water pump component 2 includes a water pump. The water pump includes a stator 21 and a rotor 22. The tank body 1 includes a tank wall; a rotor chamber 11 configured to accommodate the rotor 22 is arranged at one side of the tank wall close to inside of the tank body 1, and a rotation shaft 23 configured to support the rotor 22 and an impeller 24 connected with the rotor 22 are arranged in the rotor chamber 11. A stator chamber 31 configured to accommodate the stator 21 is arranged at one side of the tank wall close to outside of the tank body 1, and the stator chamber 31 is arranged at a position corresponding to a position of the rotor chamber 11. Since the rotor 22 and the stator 21 of the water pump are respectively arranged on an inner side and an outer side of the tank body 1, the stator 21 located outside the tank body 1 can drive the rotor 22 located inside the tank body 1 to ensure normal operation of the water pump and prevent the stator 21 and other electrified components from coming into contact with water in the tank body 1, thereby effectively preventing electric leakage of the electrified components. Since the stator 21 and other electrified components of the water pump are arranged on the outer side of the tank body 1, a power line does not need to enter the tank body 1 from an upper opening of the tank body 1, thereby increasing beautiful extent of the entire aquarium appearance.

In an embodiment, the stator 21 is encapsulated in the stator chamber 31. Since the stator 21 is encapsulated in the stator chamber 31, the water outside the tank body 1 can be effectively prevented from entering the stator chamber 31, thereby avoiding any possibility that the stator 21 contacts the water and reducing possibility of the electric leakage. In the present embodiment, the stator 21 is encapsulated in the stator chamber 31 through insulating resin.

In an embodiment, an encapsulating chamber 35 is arranged in the stator chamber 31. The stator 21 is encapsulated in the encapsulating chamber 35. This design can reduce dosage of encapsulating materials such as the insulating resin to a great extent.

In an embodiment, an isolating chamber 36 matched with the rotor chamber 11 is arranged in the encapsulating chamber 35, so as to avoid affecting the matching between the stator chamber 31 and the rotor chamber 11 caused by that the insulating resin enters a space in the isolating chamber 36 when the stator 21 is encapsulated.

In an embodiment, the rotor chamber 11 is arranged on a bottom wall 12 of the tank body 1.

In an embodiment, an accommodating groove 13 is formed concavely towards the inside of the tank body 1 at a part of the bottom wall 12 of the tank body 1; the rotor chamber 11 is formed concavely towards inside of the accommodating groove 13 at a part of a bottom plate 131 of the accommodating groove 13; an opening of the rotor chamber 11 faces to the inside of the tank body 1; the accommodating groove 13 is not communicated with the rotor chamber 11; and a height of the rotor chamber 11 is less than a height of the accommodating groove 13.

In the present embodiment, as shown in FIG. 1 to FIG. 5, an axis of the rotation shaft 23 is vertically arranged; the accommodating groove 13 is located at a center of the bottom wall 12 of the tank body 1, and presents a cylindrical shape with an open first end and a sealed second end; and the rotor chamber 11 is located at a center of the bottom plate 131 of the accommodating groove 13 and also presents a cylindrical shape with an open first end and a sealed second end. The accommodating groove 13 can be located at the center of the bottom wall 12 of the tank body 1, and can also be at any other position of the bottom wall 12 of the tank body 1. The accommodating groove 13 may be in a shape of a tank, a square tank or other special-shape structures. The rotor chamber 11 may be located at the center of the bottom plate 131 of the accommodating groove 13, and can also be at any other position of the bottom plate 131 of the accommodating groove 13. The rotor chamber 11 may be in a shape of a tank, a square tank or other special-shape structures.

The connecting plate 28 and the rotor seat 29 are detachably connected, while the water guiding cylinder 27 and the connecting plate 28 are fixedly connected, so that the water guiding cylinder 27 is directly pulled out of a water surface to conduct disassembly and maintenance work when the rotor 22 of the water pump needs to be maintained, without a need of disassembling in the tank body 1 and avoiding a limit of a narrow space, thereby reducing maintenance and disassembly difficulty, facilitating production and installation and reducing production cost.

The water outlet 252 is formed at a top of the pumping house 25; the water outlet 252 is connected with a drain pipe 26; the pumping house 25 is provided with a pumping house cover 254 which is facing away from one side of the rotor seat 29; and the water inlet 251 is formed on the pumping house cover 254. The water pumped by the water pump through the drain pipe 26 is led to the water surface and then flows back into the aquarium, so as to realize flow of the water body in the aquarium and facilitate filtration, oxygen adding and the like.

The rotor seat 29 is fixedly connected with two connecting columns. The connecting columns are connected with one side of the connecting plate 28 facing away from the water guiding cylinder 27. In an embodiment, blind threaded holes are formed in the connecting columns along the vertical direction. Through holes corresponding to the blind threaded holes are formed in the connecting plate 28. Screws penetrate through the through holes and are tightened into the blind threaded holes, so that the connecting plate 28 is connected with the connecting columns. The rotor 22, the impeller 24, the rotation shaft 23 and the pumping house 25 form a pump core component. The pump core component, the water guiding cylinder 27 and the connecting plate 28 form the water pump component 2.

A connecting plate water inlet 281 and a connecting plate water outlet 282 are formed in the connecting plate 28. The connecting plate 28 closes an upper opening of the rotor chamber 11 and an upper opening of the pumping house accommodating groove 14. The water that enters the connecting seat 15 from the lower water inlet 151 of the connecting seat 15 enters the water guiding cylinder 27 through the connecting plate water inlet 281.

The two stator iron core accommodating grooves 16 are respectively arranged at both sides of the rotor chamber 11. The accommodating groove 13 and the rotor chamber 11 may be at the center of the bottom wall 12 of the tank body 1, and can also be in any other position of the bottom wall 12 of the tank body 1. The accommodating groove 13 and the rotor chamber 11 may be in a shape of a tank, a square tank or other special-shape structures.

In an embodiment, a rear limiting apparatus configured to prevent the rotor 22 and the impeller 24 from separating from the rotation shaft 23 is arranged around the rotation shaft 23.

As shown in FIG. 15 to FIG. 21, in the present embodiment, the rear limiting apparatus at least includes a limiting mechanism 4 arranged around the rotation shaft 23 of the water pump. The rotation shaft 23 has a first rotation shaft end part 231 that extends out of the impeller 24 and a second rotation shaft end part 232 that extends out of the rotor 22. The limiting mechanism 4 is arranged between the rotor 22 and the second rotation shaft end part 232. When the rotation shaft 23 is drawn out to the outside of the rotor chamber 11, the limiting mechanism 4 arranged on the second rotation shaft end part 232 of the rotation shaft 23 can limit the rotor 22 and the impeller 24 which are installed around the rotation shaft 23 to the rotation shaft 23, so that the rotor 22 and the impeller 24 can be drawn out together with the rotation shaft 23, so as to facilitate assembly and maintenance.

The limiting sheath 41 and the second rotation shaft end part 232 of the rotation shaft 23 are connected with an interference fit. The limiting sheath 41 of rubber material and the rotation shaft 23 are connected with an interference fit, so that the limiting sheath 41 is fixed to the second rotation shaft end part 232 of the rotation shaft 23, so as to limit movement of the rotor 22 and the impeller 24 towards the second rotation shaft end part 232 along an axial direction of the rotation shaft 23 and avoid slide or drop of the rotor 22 and the impeller 24.

In another embodiment, as shown in FIG. 17 and FIG. 18, the limiting mechanism 4 includes a limiting groove 42 and a limiting clamping spring 43. The limiting groove 42 is circularly formed in the second rotation shaft end part 232 of the rotation shaft 23. The limiting clamping spring 43 is selectively clamped into the limiting groove 42, so as to limit movement of the rotor 22 and the impeller 24 towards the second rotation shaft end part 232 along the axial direction of the rotation shaft 23 and avoid slide or drop of the rotor 22 and the impeller 24.

A dimension of the clamping spring opening 433 is slightly smaller than a diameter of the groove bottom of the limiting groove 42. When the limiting clamping spring 43 is clamped with the limiting groove 42, the groove bottom of the limiting groove 42 enters the clamping hole 432 from the clamping spring opening 433. Since the dimension of the clamping spring opening 433 is smaller than the diameter of the groove bottom of the limiting groove 42, when the groove bottom of the limiting groove 42 completely enters the clamping hole 432, the clamping spring opening 433 is not extruded and elastically recovered to an original state, so as to limit the groove bottom of the limiting groove 42 into the clamping hole 432.

In an embodiment, the clamping spring body 431 is in a shape of a circular ring, and the clamping hole 432 is formed in a middle of the clamping spring body 431.

In another embodiment, as shown in FIG. 20 and FIG. 21, the limiting mechanism 4 includes a limiting hole 44 and a limiting bolt 45. The limiting hole 44 is formed in the rotation shaft 23 along a radial direction of the rotation shaft 23, and is adjacent to the second rotation shaft end part 232. The limiting bolt 45 is selectively inserted into the limiting hole 44, so as to limit movement of the rotor 22 and the impeller 24 towards the second rotation shaft end part 232 along the axial direction of the rotation shaft 23 and avoid slide or drop of the rotor 22 and the impeller 24.

In the present embodiment, the limiting hole 44 is a through hole formed along the radial direction of the rotation shaft 23. The limiting bolt 45 penetrates through the limiting hole 44, and both ends of the limiting bolt 45 extend to outside of the limiting hole 44.

A length of the limiting bolt 45 is greater than the diameter of the rotor shaft hole.

In an embodiment, an internal thread is arranged in the limiting hole 44; an external thread matched with the internal thread is arranged correspondingly at a periphery of the limiting bolt 45; and the limiting bolt 45 is screwed with the limiting hole 44 through the threads.

In other embodiments, the limiting hole 44 is a blind hole formed along the radial direction of the rotation shaft 23. One end of the limiting bolt 45 is inserted into the limiting hole 44, and the other end extends to the outside of the limiting hole 44.

A distance from an outer end of the limiting bolt 45 that extends out of the limiting hole 44 to an axis of the rotation shaft is greater than a radius of the rotor shaft hole.

In an embodiment, an internal thread is arranged in the limiting hole 44; an external thread matched with the internal thread is arranged correspondingly at a periphery of one end of the limiting bolt 45 inserted into the limiting hole 44; and the limiting bolt 45 is screwed with the limiting hole 44 through the threads.
