Detailed Description
Example 1
Referring to fig. 1 to 16, a top filtering fish tank according to the present embodiment includes a tank body a; the upper part of the cylinder body is detachably connected with a filtering component 8 for filtering water in the cylinder body; the filter component is detachably connected with a feeder B for feeding fish food.
The filtering component comprises a filtering seat 83 detachably connected to the upper end of the cylinder body, a filtering box arranged at the upper end of the filtering seat, and a water pump 84 arranged at the bottom in the cylinder body and used for pumping water in the cylinder body into the filtering box.
The lower end of the water pump is fixedly connected with a sucker tightly sucked with the bottom of the cylinder body.
L-shaped filter seat clamping plates capable of being inserted into the side wall of the cylinder body are formed on two sides of the filter seat in the length direction respectively; the side wall of the filter base clamping plate is in threaded connection with a filter base screw which is abutted against the side wall of the cylinder body, so that the filter base is fixed on the cylinder body.
The filter seat comprises a water storage tank 831 and a foam cavity 833, wherein the water storage tank 831 is located right below the filter box and used for containing filtered water, and the foam cavity 833 is formed on one side of the water storage tank and located right below the feeder.
And an overflow port 835 communicated with the material soaking cavity is formed in the upper part of the side wall of the water storage tank.
The lower end of the foam cavity is rotationally connected with a valve plate 86 driven by water in the foam cavity through a valve plate rotating shaft; when the valve plate is abutted against the lower end of the material soaking cavity, a material soaking groove for containing fish food discharged by the feeder is formed between the valve plate and the material soaking cavity; one side of the lower end of the valve plate, which is far away from the rotating shaft of the valve plate, is fixedly connected with a floater 861 which is submerged below the water surface in the cylinder body through a connecting rod.
The connecting rod is perpendicular to the valve plate, and the diameter of the connecting rod is 1-3 mm. The connecting rod has a small diameter, and the buoyancy of the part of the connecting rod which is submerged in water can not obviously influence the overall buoyancy of the floater.
A foam lower convex ring is formed at the lower end of the filter base and positioned at the periphery of the foam cavity; a hinged part is formed at the position, which is positioned at the outer side of the foam lower convex ring and close to the inner wall of the cylinder body, of the lower end of the filter seat, and a valve plate rotating hole is formed in the hinged part; and a valve plate connecting hole which is rotationally connected with the valve plate rotating hole through a valve plate rotating shaft is formed in the valve plate.
The lateral wall that the steep material chamber is located valve plate rotation hole top is arc for the fish is eaten and can drops in the valve plate upper end under the effect of self gravity, avoids the fish to eat and is detained in the steep material intracavity.
Before the feeder discharges the fish food into the soaking groove, the water pump stops working, and after the fish food is discharged into the soaking groove, the buoyancy of the floater to the valve plate is larger than the pressure in the valve plate, so that the valve plate cannot be separated from the soaking cavity, and the fish food is soaked by water in the soaking groove.
It should be noted that: the valve plate and the lower material soaking convex ring are not necessarily required to be sealed and abutted, even after the water pump is closed, the valve plate is wet, and a small amount of water is also sufficiently absorbed by dried fish food, so that the fish food absorbs water and expands. Of course, if the fish food is sufficiently expanded, it is preferable to install a seal ring at the lower end of the lower bead of the foam.
When the set soaking time is reached, the water pump works to ensure that water in the cylinder body enters the water storage tank through the filter box, and when the liquid level in the water storage tank is higher than the overflow port, the water in the water storage tank flows into the soaking tank.
When the pressure of the water in the soaking groove on the valve plate is greater than the buoyancy of the floater on the valve plate, the valve plate rotates, the valve plate is separated from the soaking cavity, and the water and fish food in the soaking groove flow into the cylinder body.
And a motor 6 for controlling the discharging of the feeder is arranged in the feeder.
A controller is arranged in the feeder; the motor and the water pump are respectively and electrically connected with the controller through leads;
before the material is discharged by the feeder, the controller controls the water pump to pause; after the feeder discharges materials, the controller controls the water pump to recover to the working state after set time.
The filter box comprises a first filter box 81 arranged at the upper end of the filter base and a plurality of second filter boxes 82 arranged between the first filter box and the filter base; the upper end of the first filter box is fixedly connected with a filter box cover 87.
