Miniature diaphragm pump upper end cover

Abstract

The invention relates to a miniature diaphragm pump upper end cover. The miniature diaphragm pump upper end cover comprises a cover body (1) covering a miniature diaphragm pump head, the cover body (1) is internally provided with a water inlet cavity (2) and a water outlet cavity (3), a water inlet pipe (4) and a water outlet pipe (5) are further arranged on the two sides of the cover body (1), the water inlet pipe (4) is communicated with the water inlet cavity (2), and the water outlet pipe (5) is communicated with the water outlet cavity (3). The miniature diaphragm pump upper end cover is characterized in that a water stopping plate (6) is arranged in the water outlet cavity (3) so that outlet water of the water outlet end of the miniature diaphragm pump head cannot directly enter the water outlet pipe (5). Compared with the prior art, the miniature diaphragm pump upper end cover has the beneficial effects that the structure is simple, the size is small, the weight is small, the number of parts is small, assembling is convenient, vibration attenuation and noise elimination can be achieved, the evacuation and self-suction capacity is strengthened, and the machining and installing cost can be greatly reduced.

Description

Technical field:

[0001] The invention belongs to the field of water pump equipment, in particular to an upper end cover of a miniature diaphragm pump. Background technique:

[0002] Micro diaphragm pump (RO pump), also known as RO booster pump, RO self-priming pump, reverse osmosis booster pump, reverse osmosis self-priming pump, etc., is a kind of DC diaphragm booster pump. The English name of the RO pump is Reverse Osmosis Diaphragm Pump, and the complete Chinese meaning is reverse osmosis (reverse osmosis) diaphragm booster pump. At present, it is one of the core accessories of the water purification industry and household water purifiers.

[0003] At present, RO pumps have relatively large vibrations and relatively large noises during use. The prior art uses a shock absorbing and noise reduction device on the outside of the RO pump head cover. For example, the publication number is CN 104776014 A, and the name is water purifier and its Disclosure of diaphragm pump asse...
