Abstract
The utility model discloses an electromagnetism exchanges pump, include the pump body, inlet port, venthole, upper air cavity, lower air cavity, go up silica gel umbrella and lower silica gel umbrella, inlet port, venthole set up respectively pump body both sides, upper air cavity is in with lower air cavity symmetric distribution on the pump body upper air cavity, lower air cavity center department have all offered the mounting hole, evenly distributed is provided with air passing hole on upper air cavity, the lower air cavity, last silica gel umbrella passes mounting hole front lock and is in upper air cavity is last, lower silica gel umbrella passes mounting hole reverse side lock and is in on the lower air cavity upper air cavity, down the outer lane of air cavity all offer flutedly, through offering the recess in the air cavity outer lane, the silica gel umbrella can directly not patted on the air cavity firmly, and the noise is little, and the silica gel umbrella is not fragile yet, and the life cycle is long, has also reduced use cost, need not frequent change, uses convenient more simply.
Description
Technical field
This utility model belongs to industrial products field, particularly to a kind of electromagnetic ac pump on health-care messaging chair.
Background technology
Health-care messaging chair needs use electromagnetic ac pump, moved back and forth by silica gel umbrella therein and pat pump housing air cavity formation air-flow, the electromagnetic ac pump of this structure can meet certain use requirement, but there is also certain defect, and silica gel umbrella is directly patted on the air cavity of plane, noise is big, silica gel umbrella is damaged greatly by the hardest beating, and silica gel umbrella uses the cycle short, virtually adds use cost, and needing frequently to change silica gel umbrella, inconvenient operation is the most complicated loaded down with trivial details.
The technical problems to be solved in the utility model is to provide that a kind of noise is little, silica gel umbrella uses cycle length, use cost simple electromagnetic ac pump low, easy to operate.
Utility model content
In order to solve, above-mentioned prior art noise is big, the cycle is short, use cost is high, operate the problems such as complicated loaded down with trivial details inconvenience for the use of silica gel umbrella, and this utility model adopts the following technical scheme that
This utility model provides a kind of electromagnetic ac pump, including the pump housing, air inlet, venthole, upper gas chamber, lower air chamber, upper silica gel umbrella and lower silica gel umbrella, described air inlet, venthole is separately positioned on described pump housing both sides, described upper gas chamber and lower air chamber are symmetrically distributed on the described pump housing, at described upper gas chamber, lower air chamber center all offers installing hole, described upper gas chamber, it is uniformly distributed on lower air chamber and is provided with air passing hole, described upper silica gel umbrella is fastened on described upper gas chamber through installing hole front, described lower silica gel umbrella is fastened on described lower air chamber through installing hole reverse side, at described upper gas chamber, the outmost turns of lower air chamber all offers groove.
The beneficial effects of the utility model are: by offering groove in air cavity outer ring, silica gel umbrella will not be patted on air cavity the most firmly, and noise is little, silica gel umbrella be not easy to damage, use the cycle long, also reduce use cost, it is not necessary to frequently change, use convenient simply.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model.
Detailed description of the invention
Describe preferred embodiment of the present utility model below in conjunction with the accompanying drawings in detail.
nullRefer to Fig. 1，A kind of electromagnetic ac pump，Including the pump housing 1、Air inlet 2、Venthole 3、Upper gas chamber 4、Lower air chamber 5、Upper silica gel umbrella and lower silica gel umbrella，Because in view reason, silica gel umbrella and lower silica gel umbrella are all not drawn into，Described air inlet 2、Venthole 3 is separately positioned on the described pump housing 1 both sides，Described upper gas chamber 4 is symmetrically distributed on the described pump housing 1 with lower air chamber 5，At described upper gas chamber 4、Lower air chamber 5 center all offers installing hole 11，Described upper gas chamber 4、It is uniformly distributed on lower air chamber 5 and is provided with air passing hole 12，Described upper silica gel umbrella is fastened on described upper gas chamber 4 through installing hole 11 front，Described lower silica gel umbrella is fastened on described lower air chamber 5 through installing hole 11 reverse side，At described upper gas chamber 4、The outmost turns of lower air chamber 5 all offers groove 13，By offering groove in air cavity outer ring，Silica gel umbrella will not be patted on air cavity the most firmly，Noise is little，Silica gel umbrella is not easy to damage，The use cycle is long，Also reduce use cost，Without frequently changing，Use convenient simply；And traditional electromagnetic ac pump silica gel umbrella is directly to pat on the air cavity of plane, noise is big, silica gel umbrella is damaged greatly by the hardest beating, silica gel umbrella uses the cycle short, virtually add use cost, and needing frequently to change silica gel umbrella, inconvenient operation is the most complicated loaded down with trivial details, can be solved by above-mentioned improvement.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, suitably change that it is done by any person of an ordinary skill in the technical field or modify, all should be regarded as without departing from patent category of the present utility model.
