Description
Technical Field
The utility model relates to a technical field of diaphragm pump, in particular to pulse diaphragm vacuum pump.
Background
A vacuum pump is generally an apparatus for obtaining a vacuum by mechanically and physically evacuating a container to be evacuated. The vacuum pump is used for pumping out gas molecules from the vacuum chamber and reducing the gas pressure in the vacuum chamber to reach the required vacuum degree.
Common vacuum pumps include dry screw vacuum pumps, water ring pumps, reciprocating pumps, slide valve pumps, rotary vane pumps, roots pumps, diffusion pumps, and the like. The vacuum pumps are generally used in industrial scenes, are generally micro diaphragm vacuum pumps used in consumption scenes at present, are widely applied to products such as breast pumps and personal care (blackhead removing instruments), and generally comprise a motor, an eccentric wheel, a swing frame, a cylinder body, a diaphragm cup, a valve plate, an umbrella nut and an upper cover. In the using process, because the vacuumizing is continuous, consumers generally have 'poor skin comfort', and therefore a vacuum pump capable of performing pulse type air suction is required to be designed to improve the skin feeling.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a simple structure can realize that the pulsed is bled, can let the consumer experience gaseous suction power, improves the pulse diaphragm vacuum pump that the consumer skin feels.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the pulse diaphragm vacuum pump is characterized in that a valve block is also arranged between the upper cover and the cylinder body, the valve block is provided with an air inlet and an air outlet which are respectively communicated with the air inlet nozzle and the air outlet nozzle, and an air inlet parachute D and an air outlet parachute D are respectively arranged in the air inlet and the air outlet to control opening; the transmission mechanism comprises a cam mechanism and a gear transmission mechanism, wherein the cam mechanism is connected with a connecting rod, and the gear transmission mechanism is connected with a motor and transmits power to the cam mechanism through a belt; the gear transmission mechanism comprises a large gear and a small gear in meshing transmission, wherein the small gear is only provided with three-third teeth, the large gear is provided with full teeth, and one third of the transmission time is idle.
In the scheme, a small gear in the gear transmission mechanism is arranged below and connected with a motor, a large gear is arranged above the small gear, and the large gear is connected with a cam mechanism through a belt pulley.
In the above scheme, the cam mechanism comprises a cam and a top block, the top block is pressed on the edge of the cam, and the top block is directly connected with the connecting rod for transmission.
In the scheme, the air inlet umbrella T and the air outlet umbrella T are arranged in opposite directions, so that an air inlet effect and an air outlet effect are achieved.
The principle of the utility model lies in that the gear with incomplete teeth is adopted for transmission, and the continuous power is one third of the power which is artificially idle, so that the interruption phenomenon in air exhaust can be realized, and the skin feeling is satisfied.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses simple structure can realize that the pulsed bleeds, can let the consumer experience gaseous suction power, improves consumer's skin sense.
