[0018] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0019] In the description, it should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be understood as indicating or implying relative importance. It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Combine the following Figures 1 to 9 The specific embodiments of the present invention are described in detail. Example 1

[0022] Reference Figures 1 to 5 This embodiment provides a fish tank with spontaneous oxygen supply and lighting functions, including a tank body 1, a base 2, a power component 3, an oxygen supply component 4, a linkage component 5 and a lighting component 6.

[0023] The top of the cylinder body 1 is open.

[0024] It should be noted that the top of the cylinder body 1 may also be designed with a cover, which can be opened when the device is working.

[0025] The base 2 is fixed on the outer side wall of the cylinder body 1 .

[0026] Specifically, the base 2 is an L-shaped base formed by splicing a horizontal plate 21 and a vertical plate 22. The vertical plate 22 is fixed to the outer wall of the cylinder body 1, and the first bracket 31 and the second bracket 41 are fixed to the horizontal plate 21. The base 2 has a simple structure and is firmly fixed.

[0027] Among them, the power component 3 includes a first bracket 31 and a connecting pipe 32, the bottom end of the first bracket 31 is fixed on the base 2, the top end of the first bracket 31 is hinged to the middle part of the connecting pipe 32 and the hinge axis is arranged horizontally, and the two ends of the connecting pipe 32 are respectively provided with an evaporation chamber 33 and a condensation chamber 34. When the evaporation chamber 33 absorbs heat or the condensation chamber 34 dissipates heat, the phase state of the working fluid in the connecting pipe 32 changes and flows to make the connecting pipe 32 rotate around the hinge axis. When the condensation chamber 34 is at the lowest position, it is higher than the evaporation chamber 33 and can contact the inner side of the top of the cylinder body 1 to dissipate heat through the water in the cylinder body 1. During operation, the connecting pipe 32 is filled with liquid working medium that evaporates at room temperature. Since the evaporation chamber 33 is lower than the condensation chamber 34, the liquid working medium is concentrated in the evaporation chamber 33. At this time, the evaporation chamber 33 is at the lowest position and the condensation chamber 34 is at the highest position. As the liquid working medium evaporates, the weight of the evaporation chamber 33 gradually decreases, so the evaporation chamber 33 will gradually rise, while the condensation chamber 34 will gradually fall. When the liquid working medium is completely evaporated and converted into a gaseous working medium, the evaporation chamber 33 is at the highest position and the condensation chamber 34 is at the lowest position. At this time, the condensation chamber 34 contacts the cold water in the cylinder body 1 for heat dissipation and cooling. The gaseous working medium in the condensation chamber 34 is converted into a liquid working medium again and gradually flows back to the evaporation chamber 33 under the action of the height difference. In this process, the evaporation chamber 33 gradually lowers and the condensation chamber 34 gradually rises. When the gaseous working medium is completely converted into a liquid working medium and flows into the evaporation chamber 33, the evaporation chamber 33 is at the lowest position and the condensation chamber 34 is at the highest position. This cycle continues.

[0028] Furthermore, in this embodiment, a heat absorption layer 35 is wrapped around the outer side of the evaporation chamber 33. The heat absorption layer 35 can improve the heat absorption efficiency to promote the evaporation of the liquid working medium.

[0029] Furthermore, in this embodiment, a water absorbing layer 36 is wrapped around the outside of the condensation chamber 34. When the condensation chamber 34 is at the lowest position, the cold water in the cylinder body 1 is absorbed by the water absorbing layer 36. In this way, even when the condensation chamber 34 rises and separates from the cylinder body 1, it is still wrapped by cold water, which is more conducive to the heat dissipation and cooling of the gaseous working medium.

[0030] Furthermore, a plurality of flagella 37 are provided at the lower part of the inner wall of the condensation chamber 34. The root of the flagella 37 is made of hard material and the top is made of flexible material. The closer the flagella 37 is to the connecting pipe 32, the shorter the length. By utilizing the structural characteristics of the flagella 37 being soft at the top and hard at the bottom and the distribution characteristics of being long far away and short near, the liquid working medium in the condensation chamber 34 can be ejected back to the evaporation chamber 33, effectively improving the reflux efficiency of the liquid working medium.

[0031] The oxygen supply assembly 4 includes a second bracket 41 and a track barrel 42. The bottom end of the second bracket 41 is fixed on the base 2. The top end of the second bracket 41 is fixedly connected to the track barrel 42. A piston 43 is provided in the track barrel 42. A closed cavity 44 is formed between the piston 43 and the bottom of the track barrel 42. The closed cavity 44 is provided with an air intake check valve 45 and an exhaust check valve 46. The exhaust check valve 46 is connected to an oxygen supply pipe 47, and the oxygen supply pipe 47 extends into the cylinder body 1. When the connecting pipe 32 rotates to drive the piston 43 away from the bottom of the track barrel 42, the volume of the sealed cavity increases and the external gas is sucked in through the air intake check valve 45; when the connecting pipe 32 rotates to drive the piston 43 close to the bottom of the track barrel 42, the volume of the sealed cavity decreases to compress the gas, and the gas is blown into the cylinder body 1 through the exhaust check valve 46 to complete the oxygen supply.

[0032] Specifically, the oxygen supply pipe 47 of this embodiment seals and penetrates the side wall of the cylinder 1 and then extends into the cylinder 1. The oxygen supply pipe 47 extends into the cylinder 1 from the side wall, which can avoid the interference of the oxygen supply pipe 47 at the top of the cylinder 1 on the movement of the connecting pipe 32, and the structural arrangement is more reasonable.

[0033] Specifically, the track barrel 42 of this embodiment is a linear barrel, the axis of which is arranged horizontally and the barrel mouth faces the linkage assembly 5.

[0034] The linkage assembly 5 is connected between the power assembly 3 and the oxygen supply assembly 4 , and the linkage assembly 5 is used to convert the rotation of the connecting pipe 32 into the movement of the piston 43 along the track barrel 42 .

[0035] Specifically, the linkage assembly 5 of this embodiment includes a disc 511, a first connecting rod 512, and a second connecting rod 513. The disc 511 is fixed relative to the connecting tube 32 and the center of the disc 511 is located on the hinge axis of the connecting tube 32. The first end of the first connecting rod 512 is hinged on the disc 511 and arranged eccentrically. The second end of the first connecting rod 512 is hinged to the first end of the second connecting rod 513, and the second end of the second connecting rod 513 is hinged to the piston member 43. During operation, the swing of the connecting tube 32 drives the disc 511 to swing, thereby driving the first connecting rod 512 and the second connecting rod 513 to drive the piston member 43 to reciprocate left and right.

[0036] Among them, the lighting assembly 6 includes a battery 61 and a lighting lamp 62, the battery 61 is fixed relative to the base 2, the lighting lamp 62 is fixed on the cylinder body 1 and electrically connected to the battery 61, a first transmission rod 63 and a second transmission rod 64 are fixed on the battery 61, a first piezoelectric ceramic 65 is provided at the end of the first transmission rod 63 away from the battery 61, the first piezoelectric ceramic 65 forms a first charging circuit with the battery 61 through the first transmission rod 63, a second piezoelectric ceramic 66 is provided at the end of the second transmission rod 64 away from the battery 61, the second piezoelectric ceramic forms a second charging circuit with the battery 61 through the second transmission rod 64, and the evaporation chamber 33 is in contact with the first piezoelectric ceramic 65 when it is in the highest position, and the condensation chamber 34 is in contact with the second piezoelectric ceramic 66 when it is in the highest position. During operation, the connecting tube 32 swings to drive the evaporation chamber 33 and the condensation chamber 34 to switch alternately to the highest position. When the evaporation chamber 33 is in the highest position, it contacts and squeezes the first piezoelectric ceramic 65, and when the condensation chamber 34 is in the highest position, it contacts and squeezes the second piezoelectric ceramic 66. The first piezoelectric ceramic 65 and the second piezoelectric ceramic 66 will generate a potential difference when squeezed by using the piezoelectric effect, and the first piezoelectric ceramic 65 forms a first charging circuit with the battery 61 through the first transmission rod 63, and the second piezoelectric ceramic forms a second charging circuit with the battery 61 through the second transmission rod 64. Therefore, the first charging circuit and the second charging circuit will generate current under the action of the potential difference, and then store it in the battery 61, so as to power the lighting lamp 62 when a power outage occurs.

[0037] Specifically, a filter may be integrated in the battery 61 to rectify and filter the unstable current generated by the first piezoelectric ceramic 65 and the second piezoelectric ceramic 66 .
