Description
Technical Field
The application relates to the technical field of ink-jet printers, in particular to a heat dissipation and exhaust system of an ink-jet printer.
Background
An ink jet printer generally has a main body including an upper compartment and a lower compartment, an ink supply system provided in the lower compartment, and an electronic system provided in the upper compartment, and a head system connected to the main body via a conduit having a plurality of pipes and wires. The ink supply system pumps ink to the nozzle system under the action of pressure, and the nozzle system controls a part of ink drops to be uncharged, and the ink drops are recycled to the ink supply system through the negative pressure recycling tank. The nozzle system controls the other part of ink drops to have different charges, and the ink drops pass through the high-voltage electrostatic field to generate deflection, and the deflected ink drops fall on the surface of the object to form characters or patterns.
When the ink supply system recovers the circulated ink from the nozzle system, some ambient air is brought into the ink supply system under the action of negative pressure, and if the ambient air cannot be discharged in time, the stability and the work of the ink supply system can be seriously affected, so that the functions of ink recovery, normal ink supply and the like are disabled. Therefore, the ink supply system is provided with an exhaust port, which is convenient for discharging the air brought in when the ink is recovered in time.
The ink-jet printer generally works continuously for a long time, electronic elements of an electronic system and electronic devices in an ink supply system generate heat, if a large amount of heat generated by the electronic elements cannot be discharged timely, the service lives of the electronic elements and the devices are shortened due to a long-term high-temperature environment, faults and damages are easily caused to the electronic system, and the operation stability and the working efficiency of the ink-jet printer are affected.
To solve the problems of heat dissipation and air exhaust of the inkjet printer, a forced air cooling scheme in which a fan and a heat dissipation hole are matched is generally used. When the electronic system compartment adopts forced air cooling to dissipate heat, more dust still enters the electronic system compartment although the air filter screen is arranged at the air inlet, so that the heat dissipation effect of the electronic system is affected. In addition, moisture in the air can be brought into the compartment of the electronic system, so that damages such as condensation and electric breakdown are caused, circuit faults are easily generated, and the service life of the electronic system is influenced. When the ink supply system compartment adopts forced air cooling to dissipate heat and exhaust, hot air exhausted by the ink supply system compartment can enter the electronic system compartment when the exhaust outlet of the ink supply system compartment is close to the air inlet of the electronic system compartment, and the hot air can have great corrosion hazard on electronic components in the electronic system.
Some prior art solutions for dissipating heat and venting ambient air through an air filter into an electronics compartment, and a high speed fan is mounted in an opening in the compartment of the electronics and ink supply compartments. The hot air in the electronic system compartment is led out to the ink supply system compartment by the fan, positive pressure is formed in the ink supply system compartment, and then the hot air and the hot air are discharged out of the ink jet printer box body through the vent hole on the bottom plate of the ink supply system compartment. The design can reduce dust from entering the compartment of the ink supply system, is beneficial to eliminating hidden danger of dust entering the ink supply system, and reduces a cooling fan.
However, the above solution does not solve the hidden trouble that dust and moisture may enter the electronic system compartment, and brings new problems that firstly, the fan guides the hot air in the high-level electronic system compartment to the low-level ink supply system compartment, and then the hot air is discharged out of the host through the lower air outlet, which does not conform to the heat dissipation principle, increases heat dissipation power consumption, and affects the service life of the heat dissipation fan. Secondly, this is not a good heat dissipation solution because the first problem that exists can raise the ambient temperature of the ink supply system compartment to a degree that is detrimental to the heat dissipation of the electronics on the ink supply system, reducing the useful life of the ink jet printer.
