Abstract
A water level control mechanism of humidifier which is composed of main body, control switch, atomizing ascillator, water tank, atomizing chamber and float ball with magnetic block features that said float ball with magnetic block works in conjunction with Hall-effect digital switches. When said float ball is driven by water level to move up and down, the Hall switch is actuated by magnetic block to measure the water level in water tank, so avoiding non-water work and ensuring high safety of humidifier.
Description
The present invention relates to a kind of water level control structure of humidifier, refer to a kind of detection aqua storage tank water level number especially and cut off the electricity supply in good time, can avoid anhydrous running takes place and the level control structure for water that damages body control circuit system.
Present humidifier is provided with probe in detecting device A (as shown in Figure 1) in storage tank, stretch to be located in the storage tank, to detect water storage tank water level; Or cooperate one to know water storage tank water level to drive near switch with ball float B in good time, and drive the control circuit System Operation of atomizer (vibration or electrothermal tube), prevent the anhydrous running of humidifier, produce dangerous.
Probe in detecting device (needle detector) is stretched in the input storage tank after being actually and utilizing transistorized base terminal to be connected in series a resistance; and this kind mode such as United States Patent (USP) the 4th; 820; No. 453; record the storage tank middle water level and drop to below the home though it has when being stretched at probe in detecting device in the storage tank; cause the water liquid in probe in detecting device and the storage tank separated; to order about the probe in detecting device provides a signal to the control circuit system; with with atomizer dump (OFF), reach the protection humidifier and prevent anhydrous situation about still turning round.
When in fact being located in storage tank and the spray chamber because of the probe in detecting device, and be full of the atomizing aqueous vapor in the spray chamber, the atomizing aqueous vapor can be attached on the terminal of probe in detecting device unavoidably, and the atomizing aqueous vapor of trace will make the probe in detecting device produce small-signal, and make the subsequent control Circuits System be in weak signal half starting state, this will cause atomizer to produce high temperature, cause to burn or hot melt decreases the body that plastic cement is made, and cause the danger in the use.
One of applicant of the present invention is the inventor of No. the 1st, 820,453, former United States Patent (USP), and the present invention is improved and developed to special research as the structural disadvantages of water level detecting at present humidifier.
The purpose of this invention is to provide a kind of water level control structure of humidifier, it is to utilize Hall switch to cooperate to place magnetic block in the ball float, reaches the effect of water level detecting to drive two of Hall switch respectively.
The present invention is achieved in that and includes body, can be installed with the control circuit system in the body, and the body top is provided with storage tank, and this storage tank is provided with atomizer, and has spray chamber above the storage tank, with temporary atomizing aqueous vapor; It is characterized in that: be provided with level switch in the storage tank, this level switch includes Hall switch, and the two sides of this Hall switch has the effect that can drive with the magnetic block that contains magnetic and make the Hall switch running; Be provided with ball float again, this ball float is provided with the hole, to be arranged in the ball float stalk, and ball float can be provided with groove, this groove is provided with magnetic block, controlled and when rising or descending by water level to utilize ball float, make magnetic block because of with two of Hall switch can be approaching respectively, thereby can drive Hall switch running (ON/ or OFF), use and know accurate water storage tank water level.
Wherein, can be provided with magnetic block in the ball float.
Characteristics of the present invention are: be provided with ball float in the storage tank in body, be provided with magnetic block in this ball float, magnetic block cooperates the Hall switch (HALL EFFECT DIGITALSWITCHES) of being located at appropriate location in the body, to detect water storage tank water level, misoperation can never be arranged.
Below in conjunction with accompanying drawing, describe structure of the present invention, feature and effect in detail.
Fig. 1 is the humidifier of traditional employing probe in detecting device.
Fig. 2 is the humidifier of traditional employing float switch.
Fig. 3 is the stereogram of humidifier embodiment of the present invention.
Fig. 4 is embodiment () schematic diagram of humidifier utilization water level detecting element of the present invention installing.
Fig. 5 is embodiment (two) schematic diagram of humidifier utilization water level detecting element of the present invention installing.
Fig. 6 drives embodiment () calcspar of the control circuit system of Hall switch for the present invention.
Fig. 7 drives embodiment (two) calcspar of the control circuit system of Hall switch for the present invention.
As shown in Figure 3, humidifier all includes body 1, can be installed with control circuit system (not shown) in the body, and utilize Hall switch 10 to start or regularly running, and body 1 top is provided with storage tank 11, and this storage tank 11 is provided with atomizer 12 (atomizer can be vibration or electrothermal tube), and the storage tank top has spray chamber 13, with temporary atomizing aqueous vapor, be guided to indoor again through outlet.
In storage tank, be provided with level switch 2, this level switch includes a Hall switch 20 (HALL EFFECT DLGITAL SWITCHES), the two sides 200,201 of this Hall switch need be driven when near by the magnetic thing that has magnetic, utilizes the magnetic field (magnetic) of magnetic thing to be driven.Be provided with ball float 21 again, this ball float has hole 210, to be arranged in the ball lever 211, limit its ascending, descending position, and ball float can be provided with groove 212, and this groove is provided with magnetic block 213,214 (as shown in Figure 4); Or only be provided with the bigger magnetic block 22 (as shown in Figure 5) of magnetic, to utilize a magnetic block 213 or 214 wherein approaching respectively with two 200,201 of Hall switch respectively, can drive Hall switch running, wherein magnetic block 213 and aforementioned one side 200 near and drive Hall switch running (ON/ or OFF) expression water level and drop to lowest water level; The expression high water level is used and is known accurate water storage tank water level near then driving Hall switch running (ON/ or OFF) with aforementioned another side 201 when magnetic block 214.
As for enforcement utilization example shown in Figure 5, be that expression utilizes the stronger magnetic block of a magnetic 22, this magnetic block 22 also is to be installed on the ball float, drive ascending, descending and can be ball float, and the ball float that magnetic block is housed is subjected to water level height and rises or descend, and can utilize magnetic block 22 and two sides 200,201 and the Hall switch 20 of Hall switch 20 to operate respectively, and its operating mode is near the side 200 or 201 with magnetic block elder generation, can drive Hall switch (ON/ or OFF), also have aforementioned effect.
Yet Hall switch 20 is in the control circuit system, and it can be as the installing mode of Fig. 6 or Fig. 7, as long as can cut off or start the running of atomizer power supply in good time, non-the present invention of installing mode of Hall switch and control circuit system can limit.
