Aforesaid a kind of novel water level switch, it is characterized in that described switch contact assembly includes the brass that is separated from each other setting and closes cutter and phosphor-copper pass cutter, between described phosphor-copper pass cutter and brass pass cutter, be provided with the little heel piece of switch, described phosphor-copper closes cutter and contacts with the pressure-sensitive diaphragm assembly, is provided with spring between the little heel piece of described switch and switch base.
The novel water level switch of aforesaid kind is characterized in that described pressure-sensitive diaphragm assembly includes diaphragm and props up the part that opens an umbrella, and props up the part that opens an umbrella at described diaphragm and is provided with pressure-sensitive diaphragm.
The novel water level switch of aforesaid kind, it is characterized in that described diaphragm props up the part that opens an umbrella and includes diaphragm and prop up the body that opens an umbrella, below propping up the body that opens an umbrella, described diaphragm is provided with supporting strut, close cutter at described phosphor-copper and be provided with connecting hole, described supporting strut passes described connecting hole and is connected on the described switch base.
The novel water level switch of aforesaid kind is characterized in that being provided with contact at the little heel piece of described switch, closes cutter at described brass and is provided with contact with described contacts mates.
In sum, the utility model with respect to its beneficial effect of prior art is:
The utility model is simple in structure, do not need directly to contact with liquid level to be measured, be not subjected to water source environment and incrusted restriction, the certainty of measurement height, functional reliability is good, wide accommodation can enrich washing facility washing procedure and consumer and according to the actual requirements numerous water levels selected, and has saved precious water resource more.
Description of drawings
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is decomposing schematic representation of the present utility model.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further described:
A kind of novel water level switch shown in Fig. 1 to 2, include switch base 1, in described switch base 1, be provided with cavity 2, in described cavity 2, be provided with switch contact assembly 3, above described switch contact assembly 3, be provided with the pressure-sensitive diaphragm assembly 4 that can trigger 3 conductings of described switch contact assembly, described switch base 1 openend of described pressure-sensitive diaphragm assembly 4 sealings, be provided with switch housing 5 at described switch base 1, be provided with air cavity between described switch housing 5 and the pressure-sensitive diaphragm assembly 4, be provided with the valve 6 that is connected with described air cavity at described switch housing 5, described valve 6 is connected by the air chamber on pressure hose is bottom washing facility.
Be provided with contact 35 at described switch bound feet spare 33 in the utility model, close cutter 31 at described brass and be provided with the contact 36 that cooperates with described contact 35.
It is mobile that pressure-sensitive diaphragm assembly 4 pressurizeds produce distortion in the utility model, pressure-sensitive diaphragm assembly 4 orders about the phosphor-copper pass cutter 32 that closes contact assembly 3 and moves down, thereby the contact of trigger switch bound feet spare 33 moves down, contact 35 on switch bound feet spare 33 contacts contacts with the contact 36 that brass closes on the cutter 31, thereby realizes conducting.
