This application claims the benefit and priority of Chinese patent application No. 202211430073.5, filed on Nov. 15, 2022, disclosure of which is hereby incorporated by reference in its entirety.
The present disclosure relates to a humidifier.
The prior art discloses a novel water drain control device for a humidifier, including a water drain structure, a support frame and a rotating shaft. The water drain structure is composed of a float, a valve rod, a spring and a water baffle. The water baffle, the valve rod and the spring are mounted on a bottom of a water tank. The spring is sleeved on the valve rod. A lower end of the valve rod abuts against a support rod end of the float, and an upper end of the valve rod is connected to the water baffle. The float, the support frame and the rotating shaft are mounted on a water chamber. The float is fixed on the support frame through the rotating shaft, and the float can swing up and down around the rotating shaft. However, the problem is that when the water tank is separated from a base, an atomizing plate is still working, resulting in safety hazards.
It is an object of the present disclosure to provide a humidifier with improved control which is characterized in that an atomizing plate stops operating when a water tank is separated from a base.
The present disclosure is implemented as follows. A humidifier with improved control includes a water tank, a base, an ultrasonic high-frequency atomizing plate, a float assembly, a drain valve and a control panel, the base being provided thereon with an atomizing chamber having an upper opening and an atomizing plate mounting base arranged on a bottom plate of the atomizing chamber, the drain valve being arranged on a bottom plate of the water tank, and the water tank detachably fits with the atomizing chamber, wherein the bottom plate of the atomizing chamber is further provided with a support seat frame and a spring seat hole.
The humidifier further includes a guide seat plate, a floating frame, a float block, a magnet, a spring and a magnetic signal generator.
The guide seat plate is fixed on the support seat frame, the magnet is pre-embedded in the floating block, and the floating block is fixed in the floating frame. The floating frame slidably fits with a guide hole on the guide seat plate. A lower end of the spring is arranged in the spring seat hole while an upper end fits with a lower end of the floating frame. A top of the floating frame fits with the bottom plate of the water tank. The magnetic signal generator is arranged inside the atomizing chamber and fits with the magnet.
The humidifier with improved control is special in that the magnetic signal generator is a reed switch or a Hall sensor.
The humidifier with improved control is special in that the top of the floating frame is provided with a transmission rod, and the transmission rod fits with the bottom plate of the water tank.
The humidifier with improved control is special in that the drain valve includes a valve core, a valve rod, a pressure spring and a valve seat arranged on the bottom plate of the water tank,
The humidifier with improved control is special in that the float assembly includes a seat body and a float;
A floor-standing fan includes a pedestal, a vertical pipe, a control box, a fan head and the humidifier as described above.
The base is provided with a vertical pipe seat, and the base extends toward the periphery in a circular direction to form a pedestal shell having a lower opening, and the pedestal is embedded into the pedestal shell.
A floor-standing fan includes a pedestal, a vertical pipe, a control box, a fan head, a mist guide pipe and the humidifier as described above. The control box includes a front box body having a rear opening and a rear box body having a front opening.
The front box body having an upper part formed with a front pipe outlet hole and a lower part formed with a front pipe inlet hole, the rear box body is formed with a recess having a rear opening, and the recess having a lower part formed with a rear pipe outlet hole and an upper part formed with a rear pipe inlet hole;
The mist guide pipe enters the control box through the front pipe inlet hole, enters the recess through the rear pipe outlet hole and is embedded into the recess, enters the control box through the rear pipe inlet hole and extends out of the control box through the front pipe outlet hole.
According to the humidifier with improved control of the present disclosure, when the water tank is separated from the base, the spring stretches, the floating frame moves upward, the magnet fits with the magnetic signal generator, and the control panel controls the atomizing plate to stop operating, thereby eliminating safety hazards.
A detailed description is provided below of embodiments of the present disclosure, examples of which embodiments are shown in the accompanying drawings on which the same or similar designator are used for representing the same or similar elements or the elements having the same or similar functions. Those embodiments described below with reference to the accompanying drawings are exemplary, which are merely to illustrate the present disclosure and cannot be understood as a restriction to the present disclosure.
As shown in
The humidifier further includes a guide seat plate 61, a floating frame 62, a float block 63, a magnet (not shown in figures), a spring and a magnetic signal generator 64.
The guide seat plate 61 is fixed on the support seat frame, the magnet is pre-embedded in the floating block 63, and the floating block 63 is fixed in the floating frame 62. The floating frame 62 slidably fits with a guide hole on the guide seat plate 61 and move up and down, a lower end of the spring is arranged in the spring seat hole 23 while an upper end fits with a lower end of the floating frame 62. A top of the floating frame 62 fits with the bottom plate of the water tank 1, and the magnetic signal generator 64 is arranged inside the atomizing chamber 21 and fits with the magnet.
The magnetic signal generator 64 is a reed switch or a Hall sensor.
The top of the floating frame 62 is provided with a transmission rod 621, and the transmission rod 621 fits with the bottom plate of the water tank 1.
When the water tank 1 is fastened to the atomizing chamber 21 of the base 2, the bottom plate of the water tank 1 fits with the transmission rod 621, the spring is compressed, and the magnet is staggered from the magnetic signal generator 64. When the water tank is separated from the base, the floating frame 62 moves upward, the magnet is opposite to the magnetic signal generator 64, the magnetic signal generator 64 transmits a signal to the control panel, and the control panel powers off the ultrasonic high-frequency atomizing plate 3, whereby stopping operating. The safety is improved.
