Referring to fig. 4-5, preferably, the heater 2 includes a heat-conducting inner tube 2-1, an outer tube 2-2, and two end caps 2-3, wherein the outer wall surface of the heat-conducting inner tube is provided with a thick-film resistor 2-11, and the outer tube 2-2 is sleeved on the heat-conducting inner tube 2-1; the two end covers 2-3 are respectively covered at two ends of the heat conduction inner pipe 2-1, and two pipe joints 2-4 are respectively arranged at the outer ends of the two end covers 2-3; one of the two pipe joints 2-4 is a water inlet joint, and the other is a water outlet joint. An inner column 2-5 is arranged in the heat conduction inner tube 2-1, a spiral edge 2-51 is arranged on the outer wall of the inner column 2-5, and a spiral channel is formed between the heat conduction inner tube 2-1 and the inner column. When the water heater works, water enters the heat conduction inner pipe 2-1 from the pipe joint 2-4 on one side, the thick film resistor 2-11 is electrified and heated to enable the temperature of the heat conduction inner pipe 2-1 to be increased, and therefore the water flowing through the heat conduction inner pipe 2-1 is heated and then flows out from the pipe joint 2-4 on the other side. The heated liquid spirally moves in the spiral channel, so that the heated liquid is in heat exchange contact with different areas of the inner wall of the heat conduction inner pipe, the liquid flowing out body is uniformly stressed, the liquid flowing path is lengthened, the heat exchange time is prolonged, the liquid and the heat conduction inner pipe can be subjected to sufficient heat exchange, the temperature of the water flowing out from the heater 2 can reach over 90 ℃, and meanwhile, the energy is saved.

Compare in traditional resistance wire direct processing in the water tank, this application adopts above-mentioned thick film heater 2 to have the programming rate fast, longe-lived, the thermal efficiency is high, very safe, environmental protection etc. and is showing the advantage.

In addition, a temperature control switch 2-6 (such as a thermistor type temperature control switch, model HCET-A/TB02) is mounted on the outer tube 2-2 and is used for detecting the temperature of the heat-conducting inner tube 2-1 and is connected with the thick film resistor 2-11 in series. Therefore, when the heat conduction inner pipe 2-1 is heated without water or with little water and is higher than a certain temperature (such as 150 ℃), the circuit is automatically cut off to stop heating, and the use is safer.

Referring to fig. 1, preferably, the cooler 3 includes a cooling tank 3-1 and a baffle 3-2 provided in the cooling tank 3-1, and the cooling tank 3-1 is filled with cooling water. Preferably, the baffle 3-2 is S-shaped. Because the cooling flow path of the water in the cooling box 3-1 is lengthened, the heat exchange time is prolonged, the liquid and the heat conduction inner pipe can be subjected to sufficient heat exchange, and the cooling of the high-temperature water can be reduced; under other equivalent conditions, the cooling box 3-1 can be designed to be smaller in external dimension.

Specifically, the two ends of the baffle pipe 3-2 are respectively connected with the heater 2 and the constant pressure water tank 4 through pipelines.

This cooler 3 is used for being less than 40 ℃ with the water cooling of route to the temperature reduction that flows out after realizing heating high temperature with heater 2, with the temperature on the high side when avoiding flowing nipple type drinking bowl 6, can guarantee the normal drinking water temperature of chicken, it is more healthy to drink water.

Referring to fig. 1 and 6, the constant pressure water tank 4 includes a tank body 4-1, a float ball 4-2 floating on the liquid surface of the tank body 4-1, and a float switch 4-4 connected to the float ball 4-2 through a connecting rod 4-3; the float switch 4-4 is arranged on the water inlet of the box body 4-1. The water fountain installation pipe 5 is horizontally arranged lower than the box body 4-1, and a plurality of nipple-type water fountains 6 are installed on the water fountain installation pipe 5.

The connecting rod 4-3 moves to drive the valve core of the float switch 4-4 to rotate so as to realize opening or closing control.

Referring to fig. 1 and 6, the float switch 4-4 is used to control the opening or closing of the water inlet of the housing 4-1. When the liquid level in the box body 4-1 is lower than the set water level, the floating ball 4-2 floats on the liquid level of the box body 4-1 and descends along with the liquid level, the floating ball 4-2 controls the floating ball switch 4-4 to be in an open state through the connecting rod 4-3, water flowing out of the cooler 3 enters the box body 4-1 from the water inlet of the box body 4-1, the liquid level in the box body 4-1 is enabled to rise continuously until the floating ball 4-2 resets when the set water level is reached, and at the moment, the floating ball 4-2 controls the floating ball switch 4-4 to be in a closed state through the connecting rod 4-3. Therefore, the automatic water replenishing can be realized in the box body 4-1, the dynamic maintenance of the liquid level position of the set water level can be realized, and the pressure of the nipple type waterer 6 provided on the waterer mounting pipe 5 in the box body 4-1 is kept constant or basically constant.

Specifically, the water outlet end of the float switch 4-4 is higher than the set water level.

Referring to fig. 1, in addition, since the drinking device mounting pipe 5 is horizontally arranged lower than the box body 4-1, a plurality of nipple-type drinking devices 6 are mounted on the drinking device mounting pipe 5. Therefore, when the drinking device mounting pipe 5 is fixedly mounted, the height H between the liquid level in the box body 4-1 and the water outlet position at the lower end of the nipple-type drinking device 6 mounted on the drinking device mounting pipe 5 is basically stabilized at a certain value (such as 300 mm). Therefore, the water outlet pressure of the nipple-type water dispenser 6 is basically constant (due to the constant height difference H), and the influence of excessive (drained) or insufficient (no drained) water pressure in the box body 4-1 on the normal work of the water outlet of the nipple-type water dispenser 6 can be avoided.

Referring to fig. 1 and 6, after water enters the tank 4-1 through the opening of the float switch 4-4, the pressure of the water is reduced and discharged, so that the influence of high pressure impact or unstable pressure on the operation of the nipple-shaped water dispenser 6 can be avoided. The water outlet pressure of the nipple-type water dispenser 6 is only related to the height of the liquid level in the box body 4-1 (under a certain condition H).

Referring to fig. 1, preferably, when the float switch 4-4 is in the closed state, the difference between the liquid level in the box 4-1 and the water outlet position at the lower end of the nipple-type drinking device 6 is 250-320 mm.

In particular, the drinking fountain mounting tube 5 may be mounted on a chicken coop. And the nipple-shaped water drinkers 6 are mounted on the water drinker mounting pipe 5 at intervals. After the device is installed, water is supplied immediately, the chicken pecks with the mouth, conditioned reflex is slowly formed after the water is pecked out, the device can be drunk at any time when people are thirsty, and manual on-off control is not needed.
