[0028] The present utility model will be further described below in conjunction with specific embodiments and the drawings.

[0029] See Figure 1-7 As shown, it is a fish tank with a high cost-effective oxygen-increasing bubble structure, which includes a fish tank main body 1 and a water pump 2. The fish tank main body 1 has a fish tank cavity 101 for holding water and an installation cavity 103 separated from the fish tank cavity 101.

[0030] The water pump 2 is arranged at the bottom of the fish tank cavity 101. The water outlet 21 of the water pump 2 is connected to a water spray pipe 3. The water spray port 31 of the water spray pipe 3 faces the inner wall of the fish tank cavity 101 and is used for spraying water towards the inner wall of the fish tank cavity 101. During operation, the water pump 2 located at the bottom of the fish tank cavity 101 pumps the water in the fish tank cavity 101, and sprays the water towards the inner wall of the fish tank cavity 101 through the water spray port 31 of the water spray pipe 3. Then the water flows back to the bottom of the fish tank cavity 101 from top to bottom, so as to achieve the effect of the up and down circulation of water, and further achieve the purpose of floating the simulated jellyfish and other simulated ornamental objects placed in the fish tank cavity 101, improving the problem that the simulated jellyfish and other simulated ornamental objects do not move, and making the ornamental effect excellent. In addition, an air inlet hole 104 communicating with the installation cavity 103 is arranged at the upper end of the fish tank main body 1. The position of the air inlet hole 104 is higher than the highest water level in the fish tank cavity 101. An air pipe joint 23 communicating with the water inlet 22 is further arranged outside the water inlet 22 of the water pump 2. The air pipe joint 23 is connected with a soft rubber air pipe 5. The other end of the soft rubber air pipe 5 passes through the installation cavity 103 and is connected to the air inlet hole 104. The air inlet hole 104 and the soft rubber air pipe 5 form an oxygen-increasing bubble structure. During use, since the position of the air inlet hole 104 is higher than the highest water level in the fish tank cavity 101, oxygen in the air can enter the air inlet hole 104, and enter the water inlet 22 of the water pump 2 through the soft rubber air pipe 5 and the air pipe joint 23, which can effectively prevent the phenomenon of water backflow. Under the rotation of the impeller in the water pump 2, after the oxygen is mixed with the water entering from the water inlet 22, it is sprayed out from the water spray port 31 of the water spray pipe 3, so that the sprayed water flow will generate more fine oxygen-increasing bubbles, which is beneficial to enhancing the oxygen concentration in the water, facilitating the improvement of the fish-raising quality, and meeting the needs of users. Moreover, the oxygen-increasing bubble structure composed of the air inlet hole 104 and the soft rubber air pipe 5 does not need to use an additional air pump to pump oxygen, has good sound insulation, and at the same time, has a simple structure, uses fewer parts, has a low manufacturing cost, and the oxygen-increasing bubble structure can generate fine oxygen-increasing bubbles in cooperation with the water pump 2, has good ornamental performance, and makes the utility model have strong market competitiveness.

[0031] The size of the water inlet 22 is larger than the inner hole size of the air pipe joint 23.

[0032] A rubber plug 6 for controlling the opening or closing of the air inlet hole 104 is arranged in the air inlet hole 104. When the oxygen-increasing bubbles do not need to be generated, the rubber plug 6 is inserted into the air inlet hole 104 to close the air inlet hole 104; when the oxygen-increasing bubbles need to be generated, the rubber plug 6 is pulled out relative to the air inlet hole 104 to open the air inlet hole 104.

[0033] Specifically, the rubber stopper 6 includes a main body portion 61, a connecting portion 62 integrally formed on one side of the lower end of the main body portion 61, and a plug body 63 integrally formed on the other side of the lower end of the main body portion 61 and used to plug into the air inlet hole 104 to close the air inlet hole 104. A blocking portion 621 protruding outward is provided in the middle of the connecting portion 62. A connecting hole 105 is provided on the upper end of the fish tank main body 1 beside the air inlet hole 104. The connecting portion 62 of the rubber stopper 6 is inserted through the connecting hole 105, and the blocking portion 621 passes through the connecting hole 105 to block at the lower end opening of the connecting hole 105, so as to ensure that the rubber stopper 6 is stably connected beside the air inlet hole 104 and avoid the problem of the rubber stopper 6 falling off and being lost. When it is not necessary to generate oxygen-increasing bubbles, the plug body 63 of the rubber stopper 6 is plugged into the air inlet hole 104 to close the air inlet hole 104; when it is necessary to generate oxygen-increasing bubbles, the plug body 63 of the rubber stopper 6 is pulled out relative to the air inlet hole 104 to open the air inlet hole 104.

[0034] In order to ensure that the plug body 63 of the rubber stopper 6 is pulled out relative to the air inlet hole 104 to open the air inlet hole 104 and also ensure that the rubber stopper 6 is stably positioned beside the air inlet hole 104, the following design is also made: A receiving groove 106 for the plug body 63 to be plugged into is further provided on the upper end of the fish tank main body 1 beside the air inlet hole 104. After the plug body 63 of the rubber stopper 6 is pulled out relative to the air inlet hole 104 to open the air inlet hole 104, the plug body 63 can be plugged into the receiving groove 106, which can ensure that the rubber stopper 6 is stably positioned beside the air inlet hole 104.

[0035] A pinch piece 64 is further provided on the outer side of the upper end of the main body portion 61, which is convenient for being pinched by hand to lift, so that the user can pull out the rubber stopper 6 relative to the air inlet hole 104, and the operation is more convenient.

[0036] A number of limiting rings 107 are provided in the installation cavity 103. The soft rubber air pipe 5 is inserted through the limiting rings 107 and fixedly assembled with the limiting rings 107, so that the soft rubber air pipe 5 is stably distributed in the installation cavity 103 and avoids bad phenomena such as excessive bending.

[0037] A bottom box 4 with a water pump cavity 41 is provided at the bottom of the fish tank main body 1. The part of the bottom box 4 in contact with the bottom of the fish tank main body 1 is sealed and connected by glue to prevent water leakage. A window 102 communicating with the water pump cavity 41 is provided at the bottom of the fish tank cavity 101. A cover plate 42 is provided in the window 102. The cover plate 42 is placed at the upper end of the bottom box 4, and the cover plate 42 has a plurality of first water inlet holes 421.

The cover plate 42 is provided with a hole position 420 adapted to the water spraying port 31. During operation, the water in the fish tank cavity 101 enters the water pump cavity 41 of the bottom box 4 through the first water inlet holes 421 of the cover plate 42, and then the water pump 2 pumps the water in the water pump cavity 41 of the bottom box 4 and sprays the water through the water spraying port 31 of the water spraying pipe 3 towards the inner wall of the fish tank cavity 101. Then the water flows back to the bottom of the fish tank cavity 101 from top to bottom, and again the water enters the water pump cavity 41 of the bottom box 4 through the first water inlet holes 421 of the cover plate 42, so as to achieve the effect of the water circulating up and down.

[0038] Wherein, a first pipe joint 43 is provided on the outer side of the bottom box 4, and a second pipe joint 44 communicating with the first pipe joint 43 is provided at a position corresponding to the first pipe joint 43 on the inner side of the bottom box 4. The soft rubber air pipe 5 is divided into two sections, namely a first soft rubber air pipe 51 and a second soft rubber air pipe 52. The two ends of the first soft rubber air pipe 51 are respectively connected to the air inlet hole 104 and the first pipe joint 43, and the two ends of the second soft rubber air pipe 52 are respectively connected to the second pipe joint 44 and the air pipe joint 23, so as to ensure that the soft rubber air pipe 5 forms a sealed assembly with the bottom box 4 and prevent water leakage. In addition, the following scheme can also be adopted: the soft rubber air pipe 5 is one section, and a sealing plug is provided on the soft rubber air pipe 5. The sealing plug is inlaid and fixed on the outer side of the bottom box 4 and forms a sealed assembly, and it can also achieve the purpose of directly connecting the soft rubber air pipe 5 to the air pipe joint 23.

[0039] The water spraying pipe 3 is in a Y shape, and the water spraying port 31 is also in a Y shape, so as to spray water towards the inner walls on both sides of the water pump cavity 41 in two directions at the same time. When the water pump 2 pumps the water in the water pump cavity 41 of the bottom box 4 and sprays the water through the water spraying port 31 of the water spraying pipe 3 towards the inner walls on both sides of the fish tank cavity 101, two water flows are formed. Then the water flows back to the bottom of the fish tank cavity 101 from top to bottom, and again the water enters the water pump cavity 41 of the bottom box 4 through the first water inlet holes 421 of the cover plate 42, so as to achieve a better effect of the water circulating up and down.

[0040] The fish tank main body 1 includes an annular inner tank 11, an annular outer tank 12 fixed to the outside of the annular inner tank 11, two transparent plates 13 respectively arranged on the front and rear end faces of the annular inner tank 11, and a detachable top cover 14 arranged at the upper end of the annular outer tank 12.

The lower end face of the annular outer tank 12 is set as a plane for supporting and positioning on the table.

[0041] In summary, when the present utility model works, the water pump 2 located at the bottom of the fish tank cavity 101 pumps the water in the fish tank cavity 101, and sprays the water towards the inner wall of the fish tank cavity 101 through the water spraying port 31 of the water spraying pipe 3. Then the water flows back to the bottom of the fish tank cavity 101 from top to bottom, so as to achieve the effect of the up and down circulating flow of the water, and further achieve the purpose of floating the simulation ornamental objects such as simulation jellyfish placed in the fish tank cavity 101, improving the problem that the simulation jellyfish and other simulation ornamental objects do not move, and making its ornamental effect excellent. The oxygen-increasing bubble structure composed of the added air inlet hole 104 and the soft rubber air pipe 5 of the present utility model, when in use, because the position of the air inlet hole 104 is higher than the highest water level in the fish tank cavity 101, the oxygen in the air can enter the air inlet hole 104, and enter the water inlet 22 of the water pump 2 through the soft rubber air pipe 5 and the air pipe joint 23, which can effectively prevent the phenomenon of water backflow. Under the rotation of the impeller in the water pump 2, after the oxygen is mixed with the water entering from the water inlet 22, it is sprayed out from the water spraying port 31 of the water spraying pipe 3, so that the sprayed water flow will generate more fine oxygen-increasing bubbles, which is beneficial to enhancing the oxygen concentration in the water, facilitating the improvement of the fish-raising quality, and meeting the needs of users; moreover, the oxygen-increasing bubble structure composed of the air inlet hole 104 and the soft rubber air pipe 5 does not need to additionally use an air pump to pump oxygen, has good sound insulation, at the same time, has a simple structure, uses fewer parts, has a low manufacturing cost, and the oxygen-increasing bubble structure cooperates with the water pump 2 to generate fine oxygen-increasing bubbles, has good ornamental property, and makes the present utility model have strong market competitiveness.
