Abstract
The utility model provides a incubator for flow detection comprises a tract, heating elements, a thermostat, a switch for flow detection and a junction box. The handspike (12) of the switch for flow detection is in the lumen (14) of the tract and the outlet box (4). A clapboard (13) is installed in front of the handspike of the switch in the lumen of the tract. The water comes into the lumen, and goes across the clapboard (13) to the handspike. So the work in reliable conding of the switch for flow detection in low water discharge is assured.
Description
Technical field
The utility model relates to a kind of electric heater unit, is a kind of message bathtub thermostat specifically.
Background technology
During thermostat work, must have water to flow and take away the heat that heater element sends, thermostat can not start or stop work when having water to flow.What adopt at present is the water delivering orifice that thermostat is installed in water pump, detects the pressure of current, and when filtrator or spray nozzle clogging, hydraulic pressure still exists the thermostat continuous working to temperature controller protection action, and thermostat still can not worked when promptly having water to flow.When thermostat is installed in the water inlet of water pump,, must adopt and detect negative pressure device, i.e. vacuum switch because the water inlet of water pump is a negative pressure.
Summary of the invention
The purpose of this utility model provides a kind of thermostat that detects flow switch that has, and can be installed in the water outlet or the water inlet of water pump, guarantees that current take away the heat that heater element sends.
The technical scheme that the utility model adopted is: thermostat is to be made of housing, heater element, temperature controller, flow detection switch, terminal box, and the push rod 12 of flow detection switch is arranged in housing inner chamber 14 and the outlet box 4; The front of switch push rod is provided with dividing plate 13 in housing.When current enter the housing inner chamber, through dividing plate 13 current are concentrated and flowed to the switch push rod, guarantee flow detection switch reliably working when low discharge.
The flow detection switch of described thermostat is made of microswitch, switch base, switch push rod, register pin, seal gasket, rubber cushion pressure ring; The fulcrum of switch push rod is provided with register pin (9), and the switch push rod is spot wobble with register pin, is provided with seal gasket (10) between switch push rod and housing inner chamber, seal gasket be axially arranged with rubber cushion pressure ring (11); The switch push rod is by seal gasket interference sealing, seal gasket axially compress sealing by the rubber cushion pressure ring.Because the switch push rod adopts lever construction, microswitch can directly be controlled the heater element power supply.
The dividing plate 13 of described thermostat becomes discrete setting with the housing one-piece construction, places the housing inner chamber, before the push rod 12 of switch; Perforate in the middle of the dividing plate, the bottom is provided with breach, the inner chamber separated into two parts of housing; Water flows through from the dividing plate perforate, and pull switch push rod, bottom small gap are used to prevent the ponding in the housing.
The terminal box 4 of described thermostat is provided with osculum 2 at following box, and osculum is designed to stepped hole, built-in filtering material; Prevent to avoid the power lead short circuit in the terminal box because the water that leaks between the inner chamber of housing and the terminal box can be drained.
Because adopt above-mentioned technical scheme, the thermostat that the utility model provides has following advance compared with prior art:
1. thermostat can be installed in the rising pipe of pump or the water inlet pipe of pump, needs the mobile thermostat of water and just works;
2. the switch push rod of flow detection switch is a spot wobble with register pin, and switch is directly controlled major loop, and is simple and reliable;
3. the flow dividing plate is set guarantees flow detection switch reliably working when low discharge.
Description of drawings
Fig. 1 is the structural representation of the utility model thermostat;
Fig. 2 is the A-A cut-away view of Fig. 1;
Fig. 3 is the synoptic diagram of switch push rod work.
Among the figure: housing 1 osculum 2 temperature controllers 3 terminal boxes 4 heater elements 5 detector switches 6 microswitches 7 switch bases 8 register pins 9 seal gaskets 10 rubber cushion pressure rings 11 switch push rods 12 dividing plates 13 housing inner chambers 14.
Embodiment
Below in conjunction with accompanying drawing and embodiment utility model is described in further detail:
Among Fig. 1, thermostat is to be made of housing 2, heater element 5, temperature controller 3, flow detection switch 6, terminal box 4, housing inner chamber 14 and the complete seal isolation of terminal box 4 inner chambers.When current enter housing inner chamber 14, through heater element 5, dividing plate 13 pull switch push rods 12, the switch push rod for a spot wobble, is depressed microswitch 7 with register pin 9, connects the power supply of heater element 5, and thermostat carries out heating work.When there not being flow out-of-date, switch push rod 12 does not stress, and switch push rod 12 resets, and microswitch 7 resets, the power supply open circuit of heater element 5.Thermostat can be installed in the rising pipe of pump or the water inlet pipe of pump, have water to flow, and well heater could be worked.
The terminal box 4 of thermostat is provided with osculum 2 at following box, and osculum is designed to stepped hole, built-in filtering material; The water that leaks out between the inner chamber of housing and the terminal box prevents owing to can be discharged.
Among Fig. 3, flow detection switch 6 is made of microswitch 7, switch base 8, switch push rod 12, register pin 9, seal gasket 10, rubber cushion pressure ring 11, microswitch 7 is on switch base 8, switch push rod 12 passes switch base 8, switch push rod 12 is by seal gasket 10 interference sealings in housing inner chamber 14, seal gasket 10 axially compress sealing by rubber cushion pressure ring 11.Switch push rod 12 is that fulcrum is swung in water (flow) direction at housing inner chamber 1 and terminal box 4 inner chambers with register pin 9.
Among Fig. 2, dividing plate 13, middle perforate, the bottom is provided with breach.Dividing plate 13 is the inner chamber separated into two parts of housing, and water flows through from the dividing plate perforate, the pull switch push rod, and bottom notch is used to prevent the ponding in the housing.
