The invention provides a miniature fish tank which is small in size and can be placed on a table top for appreciation.

Referring to fig. 1 to 5, in an embodiment of the present invention, the micro fish tank includes:

the cylinder body 10 is provided with a functional area 102 and a culture area 101, and the volume of the functional area 102 is smaller than that of the culture area 101;

the temperature control assembly is arranged in the functional area 102 and is used for controlling the temperature of the water body in the function to be constant;

the circulating pump 20 is installed in the functional area 102, and the circulating pump 20 is used for driving the functional area 102 to circularly exchange with the water body of the culture area 101; and

the algae removal assembly is used for filtering and removing algae from the water body flowing from the functional area 102 to the culture area 101.

The functional area 102 is used for controlling parameters such as temperature and algae content of the water body, and the culture area 101 is used for culturing fish or coral and other cultured objects. The shape of the cylinder 10 can be set arbitrarily, so that the functional area 102 and the culture area 101 are formed, and the volume of the functional area 102 is smaller than the volume of the culture area 101. The water bodies in the functional area 102 and the culture area 101 can circulate in each other. Therefore, the temperature control and algae removal of the water body in the culture area 101 can be realized by controlling the temperature of the water body flowing through the functional area 102 and removing algae.

The temperature control component can detect the water temperature in the functional area 102, compare the water temperature with preset constant temperature, heat the water temperature in the functional area 102 if the water temperature is less than the preset constant temperature, refrigerate the water temperature in the functional area 102 if the water temperature is greater than the preset constant temperature, so that the water temperature in the functional area 102 is consistent with the preset constant temperature through multiple times of adjustment, and the water temperature in the functional area 102 is constant. The volume of the functional region 102 is small, so that the detection of the temperature of the water body is more sensitive. Because the water in the functional region 102 is flowing, the temperature control assembly can better equalize the temperature of the water in the functional region 102 when controlling the temperature of the functional region 102.

The water inlet side of the circulation pump 20 may be disposed in the functional area 102, and the water outlet side of the circulation pump 20 may be disposed in the culture area 101. Of course, other arrangements are possible, and are not limited herein. As long as the water body circulation exchange of the functional area 102 and the culture area 101 can be realized. In the present embodiment, the water inlet side of the circulation pump 20 can be disposed in the functional area 102, and the water outlet side of the circulation pump 20 is disposed in the culture area 101. The circulation pump 20 may be disposed parallel to the bottom surface of the tank 10 or the level of the water in the tank 10, so that the circulation pump 20 may form artificial waves to simulate sea waves when it is operated. Meanwhile, when the circulating pump 20 works, the water in the functional area 102 is pumped out and discharged to the culture area 101, and the water in the culture area 101 is recirculated to the functional area 102 to supplement the reduction of the water in the functional area 102, so that the water quantities of the functional area 102 and the culture area 101 are kept constant, and a needle-type rotating water flow is formed, thereby realizing the circulating exchange between the water in the functional area 102 and the water in the culture area 101. Therefore, as long as the temperature of the water body in the functional area 102 is constant, the temperature of the water body in the culture area 101 can be constant, and a constant-temperature water area is provided for the organisms in the culture area 101. It should be noted that, the flow rate and the number of the circulating pump 20 are matched with the size of the cylinder 10, so as to ensure that the circulating pump 20 will not damage the living beings cultured in the cylinder 10 while generating a sufficient circulation flow in the cylinder 10 when in operation.

The algae removal assembly can be arranged between the water inlet 201 and the water outlet 202 of the circulating pump 20, and can be fixedly installed or detachably installed. The present embodiment may be selected such that the algae removal assembly is detachably installed at the water inlet 201 of the circulation pump 20. When the circulating pump 20 works, the algae and microorganisms gathered at the water inlet 201 of the circulating pump 20 are filtered by the algae removal assembly and are retained in the algae removal assembly. When the algae in the algae removing assembly is gathered to a certain degree, the algae removing assembly is taken out for cleaning or replacement, and at the moment, the algae in the tank body 10 is separated from the tank body 10 along with the algae removing assembly, so that the purpose of taking out and removing the algae in the tank body 10 is achieved. The algae removing component can be a filter screen, a filter plate and a filter box, namely an algae box, so as to filter algae in the water body flowing through the algae removing component.

According to the technical scheme, the tank body 10 is divided into a functional area 102 with a small volume and a culture area 101 with a large volume, the temperature of the water body in the functional area 102 is controlled by arranging a temperature control assembly, and a circulating pump 20 is arranged to drive the functional area 102 to circularly exchange with the water body in the culture area 101, so that the temperature of the water body in the culture area 101 is constant. Because only the temperature of the water body in the functional area 102 needs to be controlled, the water quantity for temperature control is less, and further the volume and the number of the constant temperature components are reduced, so that the fish tank can be made smaller. And an algae removal component is also arranged to filter and remove algae from the water flowing from the functional area 102 to the culture area 101. The invention not only meets the requirements of algae removal and constant temperature of the fish tank, but also is beneficial to the miniaturization and desktop of the fish tank. Particularly for ornamental culture objects such as coral which have high requirements on the temperature of a water body, the desktop fish tank can meet the survival requirements of the coral and save the desktop space.

Referring to fig. 2 and 3, in an embodiment, a functional region 102 of the tank body 10 is provided with a heat conduction hole, and the micro fish tank further includes a heat transfer sheet, which is mounted on the tank body 10 and blocks the heat conduction hole.

The polarity of the power voltage output to the cooling plate 52 by the reversing switch 532 is controlled to drive the end of the cooling and heat transferring plate to cool/heat, so that the temperature of the water in the cylinder 10 is constant.

The refrigerating sheet 52 may be a semiconductor refrigerating sheet 52, the semiconductor refrigerating sheet 52 includes a thermocouple pair formed by connecting an N-type semiconductor material and a P-type semiconductor material, when a forward current passes through the thermocouple pair, heat transfer occurs between the two ends, and the heat is transferred from one end to the other end, so that a temperature difference is generated to form a refrigerating end for refrigerating and a heating end for heating. When the direction of the current flowing through the thermocouple pair changes, the aforementioned refrigerating end and heating end are exchanged.

In the embodiment, the power supply flowing through the refrigerating sheet 52 is controlled, so that the refrigerating sheet 52 is reused, that is, the refrigerating sheet 52 can refrigerate and heat, and therefore, the water body constant temperature control of the culture area 101 can be realized only by arranging one refrigerating sheet 52 in the functional area 102 of the cylinder 10. Certainly, only one set of devices, such as a radiator, a controller of the refrigeration sheet 52, and the like, corresponding to the refrigeration sheet 52 is needed, which not only saves cost, but also can effectively reduce the volume of the constant temperature component, thereby reducing the volume of the miniature fish tank.

Referring to fig. 2 and 3, further, the thermostatic assembly further includes a heat conductor 551 and a fan 552, the heat conductor 551 is in abutting connection with one end of the cooling fin 52 far away from the cylinder 10, an air inlet of the fan 552 is disposed corresponding to the heat conductor 551, the heat conductor 551 guides out heat generated when the cooling fin 52 cools the cylinder 10, and the fan 552 generates air flow to dissipate heat of the heat conductor 551, so as to dissipate the heat generated when the cooling fin 52 cools the cylinder 10.

Referring to fig. 2 and 3, in an embodiment, the cylinder body 10 has a cylinder bottom and an open end 104, the cylinder body 10 is divided into a first cylinder portion 108 and a second cylinder portion 109 along the cylinder bottom to the open end 104, the second cylinder portion 109 is disposed to protrude from a first side surface of the first cylinder portion 108, the culture region 101 is disposed in the first cylinder portion 108, and the functional region 102 is disposed in the second cylinder portion 109.

The functional area 102 is provided in a protruding portion of the second cylinder 109 with respect to the first cylinder 108. The volume of the raised portion is less than the volume of the first cylinder portion 108.

Referring to fig. 2, further, a containing groove is formed between the first side surface of the first cylinder portion 108 and the second cylinder portion 109, and the refrigeration sheet 52 controller are installed in the containing groove.

In this embodiment, the size of the accommodating groove is specifically set according to the specification requirements of the controller of the refrigeration sheet 52 and the refrigeration sheet 52, and the volume requirement of the functional area 102.

In the present embodiment, a containing groove is formed between the first side surface of the first cylinder portion 108 and the second cylinder portion 109 to contain the cold plate controller and the cold plate 52. Therefore, the cold plate controller and the cold plate 52 do not need to be hung externally, so that the external shape of the miniature fish tank can be made more regular, for example, rectangular. Meanwhile, the abrasion to the controller of the refrigerating sheet 52 and the refrigerating sheet 52 in the processes of carrying, installing and using can be avoided.

Referring to fig. 3 and 3, in an embodiment, the cylinder 10 includes a bottom plate 105, a first connection plate 106, a second connection plate 107, and a plurality of transparent plates; the first connecting plate 106 is vertically arranged on the bottom plate 105, and divides the bottom plate 105 into a first section 1051 and a second section 1052, the second connecting plate 107 is connected to one end of the first connecting plate 106 far away from the bottom plate 105 and is opposite to the surface of the first section 1051 of the bottom plate 105, and the accommodating groove is defined among the first section 1051 of the bottom plate 105, the first connecting plate 106 and the second connecting plate 107;

The heat transfer fins may be mounted on the second connection plate 107, and the area of the second connection plate 107 opposite to the open end 104 is the functional region 102. The functional area 102 is near the open end 104 so that the wires of the temperature sensor 51 are electrically connected to the controller of the refrigeration pill 52 through the opening. The cooling fins 52 and the cooling fin 52 controller in the storage tank cool/heat the water body in the functional area 102 according to the temperature detection signal output by the temperature sensor 51.

The algae removing plate 30 is a plastic plate having a plurality of through holes 302 and suitable for algae adsorption

A filter plate can be arranged on the side of the algae removing plate 30 far away from the opening end 104 to isolate the algae in the illumination area 301 and prevent the algae from flowing into the culture area 101.

The two walls of the cylinder body 10 are provided with chutes matched with the algae removing plates 30, the algae removing plates 30 are clamped into the chutes for fixing, and the adsorption surface of the algae removing plates 30 is always opposite to the direction of the dark current, so that algae coming along with the dark current can directly impact on the algae removing plates 30 and enter the illumination area 301 in the holes of the algae removing plates 30. The flow speed of the dark current passing through the algae removing plate 30 is reduced, and the algae entering the illumination area 301 is not easy to come out, so that a good algae removing effect is further achieved.
