Abstract

An atomizer is provided. When the atomizer provided by the invention is used, a fan blows air to a water outlet tube, part of the airflow in the water outlet tube passes through a pressurizing tube to enter a water tank to gradually increase the air pressure in the water tank, and liquid in the water tank is pressed into a water inlet tube under high pressure, flows into a guide tube along the water inlet tube and is sprayed out of the guide tube in a direction away from the fan; after flowing out of the guide tube, the liquid is blown out by the airflow blown from the fan into the water outlet tube on the periphery of the guide tube; and the fan is used for blowing air to the water outlet tube and increasing the pressure in the water tank.

First claim

What is claimed is:

1 . An atomizer, comprising a housing, a water outlet tube, a fan for blowing air to the water outlet tube, a motor for driving the fan to rotate, a water tank, and a power supply for supplying power to the motor, wherein a guide tube for discharging water from the water outlet tube in a direction away from the fan is fixedly arranged in the water outlet tube, a pressurizing tube connected to the water tank is arranged in the water outlet tube, a water inlet tube connected to the water tank is arranged in the guide tube, and an end, away from the guide tube, of the water inlet tube is located at a bottom of an interior of the water tank;
a control switch for controlling the fan to be turned on or off and the water outlet tube to be opened or closed is arranged in the housing, the control switch comprises a push button for controlling the fan to be turned on or off and a press button for driving a regulating mechanism to move, a sliding groove used for clamping the push button and allowing the push button to reciprocate in a length direction of the push button is formed in the housing.

2 . The atomizer according to claim 1 , wherein a rotating rod is fixedly arranged in the housing, the press button is rotatably arranged on the rotating rod, the press button has a first end located below the push button and a second end leaning against the regulating mechanism, a fixed rod is fixedly arranged at a lower end of the push button, a clamping groove for clamping the fixed rod is formed in an upper surface of a side, away from the regulating mechanism, of the press button, and the push button is configured to move towards the press button in a length direction of the sliding groove and press the press button to enable the press button to rotate around the rotating rod to allow the clamping groove in the press button to rotate upwards around the rotating rod to clamp the fixed rod.

3 . The atomizer according to claim 2 , wherein a fixed pillar is fixedly arranged on an end face, facing the press button, of the fixed rod, the fixed pillar is sleeved with a spring for driving the push button to move away from the press button, a clamping seat used for clamping the spring and having an opening facing the fixed rod is fixedly arranged in the housing, and an end, away from the fixed pillar, of the spring is clamped in the clamping seat.

4 . The atomizer according to claim 2 , wherein the rotating rod is sleeved with a torsion spring for driving an end, away from the regulating mechanism, of the press button to rotate downwards around the rotating rod, a clamping pillar is fixedly arranged on the housing and located above the press button, a first end of the torsion spring is clamped on the clamping pillar, and a second end of the torsion spring is fixedly arranged on the press button.

5 . The atomizer according to claim 4 , wherein a push block is fixedly arranged at an upper end of the push button, an upper end of the push block is located on an outer side of the housing, a moving groove for clamping the push block is formed in the housing, the moving groove is longer than the push block, on and off marks are arranged on the push button, and the on and off marks are respectively located on two sides of the push block on the push button, located on a same line as the push block and parallel to the length direction of the push button.

6 . The atomizer according to claim 1 , wherein the regulating mechanism for regulating an outlet flow rate of the water outlet tube is arranged between the control switch and the water outlet tube, the regulating mechanism comprises a spline shaft rotatably arranged in the housing and a rotating ferrule disposed around the spline shaft and configured for moving in a length direction of the spline shaft, a guide groove matched with the spline shaft is formed in an inner wall of the rotating ferrule, a limiting plate used for restraining the rotating ferrule from moving in the length direction of the spline shaft is fixedly arranged on the housing, a rotating groove extending into the spline shaft is formed in a lower surface of the spline shaft, an ejector rod is movably arranged in the rotating groove by a threaded connection, guide tubes are fixedly arranged on two sides of the ejector rod, clamping grooves are fixedly arranged in the housing, the guide plates are configured to move in the clamping grooves in a length direction of the ejector rod as the ejector rod moves, and an adjusting knob for controlling the rotating ferrule to rotate is arranged on the housing.

7 . The atomizer according to claim 6 , wherein the adjusting knob is rotatably arranged on the housing, a first gear is fixedly arranged at an end, facing the ejector rod, of the rotating ferrule, a second gear always meshed with the first gear is fixedly arranged at an end, facing the rotating ferrule, of the adjusting knob, and the adjusting knob is configured to drive the rotating ferrule to rotate around a central axis of the rotating ferule by the first gear and the second gear matched with the first gear.

8 . The atomizer according to claim 7 , wherein the first gear is a bevel gear, the second gear inclines gradually towards a periphery of the adjusting knob in a direction from the adjusting knob to the rotating ferrule, and a length direction of teeth on the second gear is perpendicular to a length direction of teeth on the first gear.

9 . The atomizer according to claim 8 , wherein a spacing ring is fixedly arranged at the end, facing the ejector rod, of the rotating ferrule, the spacing ring is located in the first gear and disposed around the ejector rod, an inner diameter of the spacing ring is less than an outer diameter of the spline shaft, a positioning ring is fixedly arranged on the ejector rod, and a diameter of the positioning ring is greater than a diameter of the ejector rod and less than the inner diameter of the spacing ring.

10 . The atomizer according to claim 6 , wherein a retaining block is fixedly arranged at an end, away from the ejector rod, of the spline shaft.
