Abstract

A wide angle, atomizing-type of cleaning device for windshield of car is disclosed. The cleaning solution storage tank is heated by the energy of the engine of the car and by means of a liquid pump and an air pump, together with nozzles, the cleaning solution is atomized to clean the windshield by rapidly dissolving of the oil mist and moisture. The wiper faces little resistance from the surface of the windshield as the entire surface is provided with the atomized cleaning solution from the tank.

Claims

1. A wide angle, atomizing-type of cleaning device for windshield of a car comprising a temperature-controlled valve, a cleaning solution storage tank, a temperature controller, a heat sink, an air pump, a liquid pump and nozzles, characterized in that the heat sink is located within the storage tank and has a simple cavity structure having an inlet and outlet, and heat energy of the heat sink is obtained from heat energy of recycled engine coolant during engine operation, the temperature controller provided to the tank is used to detect the temperature of the cleaning solution so as to control the temperature-controlled valve to allow flow of such recycled engine coolant, a check valve at the outlet of the storage tank is connected to the liquid pump via a conduit, and the activation of the liquid pump to transport the liquid for pressurization also activates the air pump to produce atomized solution ejected from the nozzles comprising a nozzle body, a universal ejector, fastening device and conduits, wherein the bottom section of the nozzle body is provided with a hollow threaded solution tube and an air valve which are fastened to the hood of the car, at the front of the windshield, the threaded solution tube and the air tube are respectively connected to solution pump conduit and air pump conduit, and the universal ejector is adapted to a circular recess of an ejector body, and the front end of the ejector body is a narrow slit, and the rear and is a universal bead body, and the bead body is provided with a hollow aperture.

2. The wide angle, atomizing-type of cleaning device as set forth in claim 1, wherein the temperature controller is adjustable to comply with the climate of various regions.

3. A wide angle, atomizing-type of cleaning device for windshield of a car comprising a temperature-controlled valve, a cleaning solution storage tank, a temperature controller, a heater, an air pump, a liquid pump and nozzles, characterized in that the heater is located within the storage tank and has a simple cavity structure having an inlet and outlet, and heat energy of the heater is obtained from heat energy of recycled engine coolant during engine operation, the temperature controller provided to the tank is used to detect the temperature of the cleaning solution so as to control the temperature-controlled valve to allow flow of such recycled engine coolant, a check valve at the outlet of the storage tank is connected to the liquid pump via a conduit, and the activation of the liquid pump to transport the liquid for pressurization also activates the air pump to produce atomized solution ejected from the nozzles comprising a nozzle body, a universal ejector, fastening device and conduits, wherein the bottom section of the nozzle body is provided with a hollow threaded solution tube and an air valve which are fastened to the hood of the car, at the front of the windshield, the threaded solution tube and the air tube are respectively connected to solution pump conduit and air pump conduit, and the universal ejector is adapted to a circular recess of an ejector body, and the front end of the ejector body is a narrow slit, and the rear and is a universal bead body, and the bead body is provided with a hollow aperture.
