Definitions

  • This invention relates to a humidifier, particularly to one having a body and a water storing tank and a float fitted around a water outlet of the water tank to move up and down together with the level of water in a water chamber of the body so as to drive a water level sensor to turning on and off the humidifier.
  • a known conventional humidifier shown in Figs. 1 and 2 includes a water level sensor S disposed in a water-storing tank A, and a float S1 fixed at an outer circumference or one side of the water level sensor S.
  • the float S1 rises up and down together with the level of the water in the water storing tank A, and the water level sensor S is controlled by the float S1 to turn on or off. So when the float S1 falls down to the lowest water level, the water level sensor S may turn off the control electric circuit of the humidifier to prevent a heater or an ultrasonic oscillator from burning and also the humidifier from becoming out of order.
  • the float When the water level is normal or in the scope except the lowest level, the float can keep turning on the control electric circuit and subsequently turn on the switch of the humidifier. But provided the humidifier is placed to lie lateral or upside down, the float always stays at the highest water level or in the effective scope to always turn on the control electric circuit, even if there left no water in the water storing tank A or water flows into an upper cap. Then the float S1 may permit the water level sensor S sense wrongly that the water in the water storing tank A has its level in the standard scope to let the switch of the humidifier always turning on. Then the heater of the humidifier may be heated up idle or the ultrasonic oscillator may be burned to cause disorder of the humidifier and danger to a user.
  • the objective of the invention is to offer a humidifier having a float formed as integral with a bottom base of a water tank, making the humidifier and a user safe.
  • the feature of the invention is a float combined with the bottom base of the water tank and near a water outlet of the water tank and separated together with a water level sensor when the water tank is removed from the humidifier. So malfunction of the water level sensor never happens, and in addition, the float is located near the water outlet, easily sensing the lowest water level in the water tank to let the sensor turn off the power of the humidifier to protect it.
  • a preferred embodiment of a humidifier in the present invention includes a body 1 having a switch 10, a water chamber 11 and a water level sensor 12, a water storing tank 2, and a cap 13 as main components combined together.
  • the water level sensor 12 may be an infrared sensor shown in Figs. 5 and 6, a HALL effect digital switch or a near switch or any element having the same function, normally deposited in the water chamber 11 of the body 1.
  • the cap 13 has an insert hole 130 formed in one side for receiving the lower portion of the water tank 2.
  • the water storing tank 2 is a bellows-type tank 20, as shown in Fig. 3, or a common tank such as made of hard plastic, combined with a bottom base 21, which has a conical wall 22 closely fitting a bottom portion of the water tank 2 to prevent water from leaking out, a female threads portion 220 extending down from the conical wall 22 to engage with a male threads portion of the bottom portion of the water tank 2, and an outer cylindrical portion 221 under the conical wall 22 and having the same outer diameter as the inner diameter of the insert hole 130 of the cap 13 so that the bottom base 21 together with the water tank 2 may quickly assembled with or disassembled from the cap 13 and the body 1.
  • the conical wall 22 has a water hole 23 in its bottom and a stopper 24 for closing the water hole 23 in case of stopping water to fall in the body 1.
  • a connect rod 25 is provided, and a coil spring 26 fitting around the connect rod 25, and the upper end of the connect rod 25 screws with the stopper 24 by means of a nut.
  • An inner cylindrical member 3 is vertically provided in the bottom base 21, located under the water hole 23 and extending down to protrude out of the bottom of the bottom base 21, having plural connect annular walls 30 formed in an upper end and connected to an annular wall of the water hole 23.
  • the plural connect annular walls 30 have plural water gaps 231 for water to fall through into the water chamber 11 of the body 1.
  • a small cylinder 31 is provided in the center of the connect wall 30 for the connect rod to pass through, having an annular spring recess 310 for a receiving a spring 26 to be compressed or resiliently push back the small cylinder 31.
  • the inner cylindrical member 3 has plural grooves 32 formed in a bottom and a hook member 330 formed on an outer bottom end of each divided wall 33 of the cylindrical member 3.
  • Each divided wall 33 has elasticity to expand or shrink back by means of the plural grooves 32.
  • the lower end of the connect rod 25 is pushed up by the bottom base 120 of the water level sensor 12, forcing up the stopper 24 to open the water hole 23, permitting the water in the water tank 2 to flow into the water chamber 11 of the body 1 or to permit the water tank 2 communicate with the body 1.
  • the annular float 4 fits around the inner cylindrical member 3 as shown in Figs. 7 and 8, the float 4 moves up and down together with the water level in the water chamber 11, raising up and down accordingly the inner cylindrical member 3 to decide function of the water level sensor 12 to turn or off the humidifier.
  • the purpose of positioning the float 4 at the bottom of the bottom base 21 and near the water chamber 11 of the body 1 is to acquire the best water level condition in the water chamber 11 in the body 1, improving the disadvantage of the conventional humidifier having a float deposited in the water tank.
  • the float 4 even if the humidifier should fall down to lie laterally, malfunction of the water level sensor may not happen to keep safe the humidifier and a user.
