The water pump of water purifier is made up of upper flow room and lower motor room, pushing device is provided with between fluid chamber and motor room, and be provided with waterproof construction between fluid chamber and motor room, prevent the current in fluid chamber from overflowing in motor room, and fluid chamber also requires to have good sealing effect, prevent to leak or flooded conditions, what the fluid chamber sealing configuration of existing water purifier water pump adopted seals the flexible sheet that is spirally connected between fluid chamber cap and fluid chamber's support, the sealing effect between fluid chamber cap and fluid chamber's support is ensured by the coupling mechanism force extruding flexible sheet that is spirally connected, this sealing configuration finds after reality uses, or the phenomenon that sealing effect is bad.
Model utility content
The purpose of this utility model is the fluid chamber's triple seal structure providing a kind of water purifier water pump, and it has and prevents from leaking in fluid chamber or the feature of triple seal of flooded conditions.
For achieving the above object, the utility model adopts following technical proposals:
A kind of fluid chamber's triple seal structure of water purifier water pump, comprise fluid chamber cap, diaphragm, be spirally connected bottom described diaphragm and fluid chamber cap, fluid chamber is provided with in described fluid chamber cap, water inlet is provided with on the left of described fluid chamber tops, osculum is provided with on the right side of described fluid chamber tops, described water inlet, osculum, fluid chamber communicates, seal groove is provided with bottom described fluid chamber, described diaphragm top is provided with the sealing flange collar corresponding with seal groove, described seal groove inner side surface is sealing surface, sealed step is provided with bottom described sealing surface, the seal groove outer place of described fluid chamber cap bottom surface is provided with seal ring.
Wherein, described sealing surface is plane of inclination, and angle of inclination is set between 6 ~ 15 °.
Wherein, concordant with bottom sealing surface inside described seal ring, be inclined-plane outside described seal ring.
Wherein, described seal ring and fluid chamber cap are formed in one structure.
Wherein, the internal diameter of described sealed step is less than seal groove internal diameter, and the external diameter of described sealed step is consistent with sealing surface top diameter.
Wherein, described sealed step and fluid chamber cap are formed in one structure.
The utility model beneficial effect: the utility model comprises fluid chamber cap, diaphragm, be spirally connected bottom described diaphragm and fluid chamber cap, fluid chamber is provided with in described fluid chamber cap, water inlet is provided with on the left of described fluid chamber tops, osculum is provided with on the right side of described fluid chamber tops, described water inlet, osculum, fluid chamber communicates, seal groove is provided with bottom described fluid chamber, described diaphragm top is provided with the sealing flange collar corresponding with seal groove, described seal groove inner side surface is sealing surface, sealed step is provided with bottom described sealing surface, the seal groove outer place of described fluid chamber cap bottom surface is provided with seal ring, the utility model is by being set to plane of inclination by sealing surface, when diaphragm and fluid chamber's cover locking, sealing flange collar reaches the first resealing effect through the stressed extruding of sealing surface, sealed step simultaneously bottom seal groove and the sealing stressed sealing in flange collar top, reach the second resealing effect, seal ring additionally by limit, seal groove outer plays side seal to sealing flange collar, reach triple seal effect, therefore fluid chamber cap and diaphragm is made to have the effect of triple seal, effectively prevent overflow or water leakage situation.
