Abstract
The utility model discloses a floating ball type liquid level control switch for electric water heaters, comprising a floating ball. The floating ball is fixedly connected with the top end of a lever type drive shaft. The tail end of the drive shaft and a spring press sheet are in movable fit. The lower part of the spring press sheet is provided with a movable top core. The upper end of the movable top core and the spring press sheet are in movable fit. The lower end of the movable top core and the electrode moving sheet of the contact switch are in movable fit. The utility model is widely suitable for liquid electric heating products of electric water kettles, electric water heaters, etc.
Description
The utility model relates to a kind of float-ball type liquid level control switch that is used for electric heater.
The electric heating water heater of Xiao Shouing in the market, it comprises insulating pot, many products such as electric heating shower, this product can be easy to water the water in the container dried as using accidentally.Therefore and the dangerous accident that produces often has generation, for guaranteeing safe handling electric heating water heater, people now adopt metal fever distortion temperature detect switch (TDS) are installed in described electric heating water heater, thereby reach the purpose that prevents that water dryouies in the described container by control to water temperature in the container, but the effect of this temperature detect switch (TDS) is unsatisfactory, and it can not fundamentally solve in the described container water by the dangerous accident of dryouting and producing.
The purpose of this utility model is to provide a kind of safe and reliable, can fundamentally solve the float-ball type liquid level control switch that water is dryouied in the electric heating hot water tank.
The purpose of this utility model is achieved in that this liquid level control switch, it comprises the contact switch that an electrode stator, an electrode moving plate and housing are formed, it is characterized in that it also comprises a ball float, this ball float is fixedly connected on the top of a lever power transmission shaft, this transmission the tip of the axis is provided with a contact, by this contact a described power transmission shaft and a spring pressuring plate are movingly, have a movable plunger tip at this spring pressuring plate, the upper end of this activity plunger tip and described spring pressuring plate are movingly, and its lower end and described electrode moving plate also are movingly.
The utility model is to utilize described ball float control liquid level, thereby and utilize lever with the described spring pressuring plate of ball float knee-action transmission, movable plunger tip and electrode moving plate; When liquid level descended, described ball float fell and drives lever action, thereby the pressuring spring compressing tablet presses down, and backed down the electrode moving plate by spring pressuring plate transmission activity plunger tip, made power cut-off; When liquid level rose, described ball float also rose thereupon, and described spring leaf, movable plunger tip and electrode moving plate reset, thereby make electrode moving plate and the adhesive of electrode stator, energized.Therefore, the utlity model has advantages such as simple in structure, safe and reliable, it can fundamentally solve the anti-generation of dryouting accident of electric heater.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Describe structure in detail below in conjunction with Fig. 1 according to the concrete liquid level control switch that the utility model proposes.
This liquid level control switch, it comprises a contact switch, this contact switch is by an electrode stator 1, one electrode moving plate 2 is formed with the housing 3 that is used for fixing described electrode moving plate 2 and electrode stator 1, it also comprises a metal ball float 4, this ball float is fixedly connected on the top of a lever power transmission shaft 5, this transmission the tip of the axis is provided with a contact 5-1, by this contact a described power transmission shaft 5 and a spring pressuring plate 6 are movingly, have a movable plunger tip 7 at this spring pressuring plate 6, the upper end of this activity plunger tip 7 and described spring pressuring plate 6 are movingly, its lower end and described electrode moving plate 2 are movingly, one end of the end of described power transmission shaft 5 and described spring pressuring plate 6 all is connected on the support 8, this support 8 is provided with a shouldered through hole 8-1, described movable plunger tip 7 is located among the through hole 8-1 on the described support 8, described support 8 and described housing 3 are adjacent and by the fixture (not shown), for example: screw, nut with above-mentioned both link together, be provided with an anti-sealing cap 9 that leaks between described support 8 and described housing 3, sealing cap 9 can adopt silastic material to make.
When using the utility model, only need described liquid level control switch is installed in the bottom of electric heating hot water tank, and the electrode moving plate of described contact switch and electrode stator be connected in the original electric power loop get final product.
Claims (5)
