Description

Technical Field

[0001] The utility model relates to the technical field of ventilation fans, in particular to a window fan with alarm, dustproof and fresh air functions. Background Art

[0002] The traditional function of the ventilation fan is to output wind force by driving the fan blades to rotate through the operation of the motor, and the wind force causes fluctuations in the air in the environment, thereby generating wind force to ventilate the space and convey wind. However, since the traditional ventilation fan only generates wind force by driving the fan blades to rotate through the motor to output wind force, the fan blades generate a driving force for air flow when they rotate. The flow of air in the environment causes outdoor air to be drawn into the room along with the indoor air flow, which easily attracts outdoor dust or mosquitoes into the room, causing the indoor air to be polluted by dust and the mosquitoes generated to have a greater impact on the people indoors.

[0003] Therefore, the utility model provides a window fan with three functions of alarm, dust prevention and fresh air. Utility Model Content

[0004] The utility model aims to provide a window fan with three functions of alarm, dust prevention and fresh air, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A window fan with alarm, dust prevention and fresh air, comprising a mounting base, a fan blade arranged in the mounting base, and a panel covering the fan blade in the mounting base, wherein the fan blade is arranged in the mounting base and connected to a motor in the mounting base;

[0007] A track bar is provided on the inner side wall of the mounting base and in front of the corresponding fan blade, and a filter screen slide groove is provided in the track bar, and a filter screen covering the fan blade is slidably installed in front of the fan blade through the filter screen slide groove;

[0008] The panel is fitted with the front side of the mounting base, and four buckles at the four corners of the panel are respectively fixed with the four corners of the mounting base.

[0009] Furthermore, both ends of the bottom surface of the mounting base are respectively provided with feet for stably supporting the mounting base on a plane, and the assembled fan is supported on a use platform through the feet to maintain the stability of the fan when in use.

[0010] Furthermore, a touch alarm is provided on the top surface of the mounting base. The touch alarm is a touch-type alarm and is arranged in the direction of window opening. When the window at the fan assembly location is opened, the opened window contacts the contact alarm to remind the user that the window is opened. The user can decide whether to close the window according to the needs of the indoor environment.

[0011] Furthermore, the panel is provided with an air outlet grille for cooperating with the wind output, and a control panel for controlling the operation of the motor is provided on the panel. The air outlet grille is used to cooperate with the wind flow output generated by the rotation of the fan blades, and cooperate with the installation base to limit the filter between the fan blades and the inner side of the panel, thereby ensuring that the wind flow is filtered through the filter and then output to the indoor space.

[0012] Furthermore, the filter is made of an accordion-type filter and the folds at the top of the filter are connected to a slider in the filter slot. When the filter needs to be cleaned, the filter can be folded or unfolded by the slider. During the folding or unfolding process, a vibration amplitude is generated on the filter, thereby shaking off and cleaning the dust on the surface of the filter.

[0013] Furthermore, the motor adopts a reversible motor setting and a wire pressing plate is provided in the mounting base for cooperating with the motor and fixing the motor connecting wires. The wire pressing plate fixes the wires connected to the motor to avoid the wires being entangled in the mounting base and being touched by the fan blades.

[0014] Furthermore, an air inlet filter is vertically clamped at the air inlet end of the mounting base through a clamping position, and the air inlet filter is used for preliminarily filtering impurities in the outdoor air when the fan blades in the mounting base are running to transport the outdoor air to the indoor.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The window fan with alarm, dust prevention and fresh air has a filter installed in the installation base through a track bar and the filter is arranged in front of the fan blade. The assembled fan is installed on the indoor window. When the fan blade generates a rotating wind force through the operation of the motor, the outdoor air enters the room with the wind force generated by the rotation of the fan blade. The indoor air needs to be filtered by the filter before entering the room, so as to prevent outdoor mosquitoes and dust from entering the room and causing adverse effects on the indoor air.

[0017] The motor is reversible. When the indoor air needs to be exhausted for ventilation, the motor drives the fan blades to reverse, so that the fan blades reverse and exhaust the indoor air to the outside. The fan blades run forward and backward to input fresh air into the room or to create a new air for indoor ventilation.

[0018] A touch alarm that senses the opening of the window is arranged on the mounting base. Since it is arranged in the direction of the window opening, when the window at the fan assembly location is opened, the opened window contacts the contact alarm to remind the user that the window is opened. The user can decide whether to close the window according to the indoor environment. BRIEF DESCRIPTION OF THE DRAWINGS
