Abstract
The utility model discloses a highly reliable vacuum motor which comprises a vacuum connection port, a spring, an air hole, a connection rod, a membrane and a casing. The connection rod is arranged on the casing in a penetrating mode, the spring is arranged outside the connection rod, one end of the spring is provided with the membrane, one end of the connection rod is provided with the vacuum connection port, and the air hole is arranged on the casing. The vacuum motor is capable of accurately controlling the position of the connection rod so that the full opening or the full closing of a ventilation door or a hot water valve is achieved, the moving is stable and reliable, and the defect that traditional vacuum motors can not achieve accurate positioning is overcome.
Description
Technical field
The utility model relates to a kind of highly reliable vacuum motor.
Background technique
Vacuum motor is claimed vacuum motor again; Box or vacuum driven device are carried out in vibration; His essence effect is to change vacuum signal into machinery action; Drive various air doors or water valve with this, but the vacuum motor on the market is because of transmitting instability, caused opening and closing and do not accomplish accurate in locating air door or water valve.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, to provide a kind of simple in structure, the stable and reliable operation vacuum motor.
Technological scheme: in order to realize above purpose, the described a kind of highly reliable vacuum motor of the utility model, it comprises vacuum interface; Spring, pore, connecting rod; Diaphragm and housing, described connecting rod is arranged on the housing, and the outside of connecting rod is provided with spring; One end of spring is provided with diaphragm, and described connecting rod one end is provided with vacuum interface, and described housing is provided with pore.
Beneficial effect: a kind of highly reliable vacuum motor that the utility model provides on diaphragm, makes diaphragm move down through vacuum action under the effect of atmospheric pressure; Drivening rod moves downward, and when cutting off vacuum source, moves on the diaphragm making under the effect of spring; Make connecting rod reset, control the corresponding air door or the standard-sized sheet or the full cut-off of water valve with this, this vacuum motor is simple in structure; And move reliable and stablely, overcome the shortcoming that accurate position do not accomplished action by the traditional vacuum motor.
Description of drawings
Fig. 1 is the working principle schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
Be illustrated in figure 1 as the described a kind of highly reliable vacuum motor of the utility model, it comprises vacuum interface 1, spring 2, pore 3, connecting rod 4, diaphragm 5 and housing 6.
Described connecting rod 4 is arranged on the housing 6, and the outside of connecting rod 4 is provided with spring 2, and an end of spring 2 is provided with diaphragm 5, and described connecting rod 4 one ends are provided with vacuum interface 1, and described housing 6 is provided with pore 3.
Open vacuum source, and link to each other with vacuum interface 1, vacuum action is on diaphragm 5 at this moment, and diaphragm 5 moves down under the effect of atmospheric pressure, thereby makes spring 2 compressions, and drivening rod moves downward.When cutting off vacuum source, under the effect of spring 2, diaphragm 5 moves up, thereby resetting of drivening rod 4 controlled the corresponding air door or the standard-sized sheet or the full cut-off of water valve with this.
This vacuum motor realized the standard-sized sheet or the full cut-off of air door or water valve through the position of control link 4 accurately, and moves reliable and stablely, overcome the shortcoming that accurate position do not accomplished action by the traditional vacuum motor.
Above-mentioned embodiment only is the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
