Abstract
The embodiment of the utility model discloses a vacuum air suction pump, which comprises a motor and an air collection assembly, wherein the air collection assembly is fixedly connected to one end of an output shaft of the motor, the output shaft of the motor extends into a casing of the air collection assembly, a sealing pad connected with the casing in a sealed way is also arranged in a through hole arranged on the casing for the output shaft of the motor to stretch, and the output shaft of the motor passes through a through hole arranged on the sealing pad and extends into the casing. The vacuum air suction pump provided by the embodiment of the utility model is characterized in that the sealing pad connected with the casing in the sealed way is arranged in the through hole, and the output shaft of the motor passes through the through hole arranged on the sealing pad and extends into the casing, so the vacuum air suction pump reaches the technical effects that the sealing performance is good, the vacuum air suction quantity is stable, and the vacuum degree is high. The air suction efficiency is further improved, and the energy consumption is reduced.
Description
Technical field
The utility model relates to the vacuum suction technology, relates in particular to a kind of vacuum suction pump.
Background technique
The vacuum suction pump that uses in existing vacuum suction pump such as the small size vacuum wrapping machine generally includes motor and by motor-driven gas collection assembly; The output shaft of motor stretches in the housing of gas collection assembly, seals owing to only rely on size to cooperate between the bearing on motor output shaft and the housing, and its sealability is relatively poor; When carrying out air-breathing work; Ambient air is prone to get into from the joint of motor and housing, makes the vacuum suction amount unstable, and degree of vacuum is less than normal.
The model utility content
The utility model embodiment technical problem to be solved is, a kind of good seal performance is provided, and the vacuum suction amount is stable, the vacuum suction pump that degree of vacuum is high.
In order to solve the problems of the technologies described above; The utility model embodiment has proposed a kind of vacuum suction pump; Comprise motor, be fixedly connected on the gas collection assembly of output shaft one end of said motor; The output shaft of motor stretches in the housing of gas collection assembly, also is provided with the sealing gasket that is connected with housing seal in the through hole that the output shaft of the power supply machine on the said housing stretches into, and the output shaft of motor passes the perforation on the said sealing gasket and stretches in the housing.
Further, perforation on the said sealing gasket and said output shaft are zero tolerance fit or interference fit.
Further, the position that contacts with output shaft motor said perforation is towards the semicircle protrusion of output shaft direction.
Further, said sealing gasket is plate-like.
Further, said through hole is the narrow shoulder hole in wide the inner, outer end, and said sealing gasket is the stepped sealing gasket that is complementary with shape of through holes.
The utility model embodiment's vacuum suction pump is through being provided with the sealing gasket that is connected with housing seal in through hole; The output shaft of motor passes the perforation on the said sealing gasket and stretches in the housing; Thereby make the vacuum suction pump reach good seal performance, the vacuum suction amount is stable, the technique effect that degree of vacuum is high; Further improve gettering efficiency, reduced energy consumption.
Description of drawings
Fig. 1 is the generalized section of the utility model embodiment's vacuum suction pump.
Fig. 2 is the enlarged diagram at A place among Fig. 1.
Fig. 3 is the motor shown in Figure 1 and the structural representation of sealing gasket.
Embodiment
The vacuum suction pump that the utility model embodiment provides; The main improvement is inlet end; Set up sealing gasket in the through hole with housing, make the vacuum suction pump guarantee that when air-breathing gas can only get into from suction port uniquely, thereby guaranteed condition of high vacuum degree; Improve vacuum suction efficient, reduced the consumption of the unnecessary operating current of vacuum suction pump.
Please refer to Fig. 1 ~ Fig. 3, the utility model embodiment's vacuum suction pump comprises motor 10, gas collection assembly 20 and sealing gasket 30.
Said motor 10 is provided with the output shaft 11 that is used for outputting power.
Said gas collection assembly 20 is fixedly connected on output shaft 11 1 ends of said motor 10, is used for carrying out vacuum suction by said motor 10 drivings.Said gas collection assembly 20 comprises housing 21, and housing 21 is provided with the through hole 25 that the output shaft 11 of suction port 23 and power supply machine 10 stretches into, and said through hole 25 is the narrow shoulder hole in wide the inner, outer end.Said gas collection assembly 20 also comprises miscellaneous part certainly, because of irrelevant with the utility model, repeats no more.
Sealing gasket 30 is located in the said through hole 25, be tightly connected with said housing 21, for through hole 25 shapes be complementary stepped, be used to prevent that gas from getting into said gas collection assembly 20.Said sealing gasket 30 is plate-like, is specially discoid or the square plate shape.
From the above mentioned, the utility model embodiment's vacuum suction pump is provided with the sealing gasket 30 that is tightly connected with housing 21 in said through hole 25, thereby prevents that gas from getting into from the joint of motor 10 with housing 21; Said perforation 31 is zero tolerance fit or interference fit with said output shaft 11; And protrude towards output shaft 11 directions are semicircle at the position that contacts with output shaft 11 motor 10 said perforation 31, thereby prevent that gas from getting into output shaft 11 and gap bearing between the entering of motor 10 backs along motor 10 from the hole of motor 10 outer surfaces, and then make the vacuum suction pump reach good seal performance; The vacuum suction amount is stable; The technique effect that degree of vacuum is high has further improved gettering efficiency, has reduced energy consumption.
The above is the embodiment of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also are regarded as the protection domain of the utility model.
