Description

High-pressure micro-mist humidifier

Technical Field

The application relates to the field of electric appliances, in particular to a high-pressure micro-mist humidifier.

Background

The high-pressure micro-mist humidifier is an electric appliance frequently used by people and used for improving the humidity of air. The working principle of the high-pressure micro-mist humidifier is that a high-pressure plunger pump is utilized to increase the water pressure to 4-7Mpa, then the pressurized water is atomized by a professional nozzle through a high-pressure resistant transmission pipeline to generate micro-mist particles with the particle size of 3-15 mu m, so that the micro-mist particles can quickly absorb heat from air to complete vaporization and diffusion, and the purposes of air humidification and cooling are achieved. When the plunger pump works, the temperature of the plunger pump rises, and when the temperature reaches 80 ℃, the plunger pump starts to age rapidly until being damaged, so that the water seal of the plunger pump is not tight, and the output pressure is reduced. The method of the common humidifier for the sensor is to control the temperature of a pump head of the plunger pump by installing an external backwater pressure regulating valve and a temperature control or temperature mode, because the humidifier basically keeps the piston stroke and the action times of the plunger pump unchanged or slightly reduces the action times (the action times are reduced by regulating the rotating speed of a motor through a frequency converter) when the flow is output in a variable mode, in order to ensure that the temperature of the pump head is not continuously increased, the external backwater is discharged or is led back to a water tank again, so that far continuous low-temperature water can be cooled for the plunger pump ceaselessly when passing through the pump head continuously, and the pump can work continuously. In view of the above problems, no high pressure micro-mist humidifier can solve the problems of the prior art.

Through above-mentioned device, in order to consume the energy to the technical problem for giving plunger pump 140 cooling among the prior art has been solved.

Further, water is introduced into the water tank 120 through the inlet pipe 1112 of the water inlet 111, the ball float 126 floats with the rise or fall of the liquid in the water tank 120, and when the liquid in the water tank 120 reaches a predetermined level, the ball float 126 rises, thereby closing the inlet pipe 1112. When the liquid in the tank 120 descends, the ball float 126 descends along with the liquid, and the water inlet pipe 1112 is opened, so that the tank 120 is replenished. In this way, the liquid in the water tank 120 is ensured not to overflow, and meanwhile, the water in the water tank 120 is ensured to be always kept with a certain amount of liquid, thereby further saving water sources. Then, the water in the water tank 120 enters the plunger pump 140 through the connection water pipe 121 to cool the plunger pump 140.
