Abstract
The utility model discloses a low-noise medical nebulizer pump which comprises a cylinder. One side of the cylinder is connected with a motor, a buffer is installed on the other side of the cylinder, a rotating shaft of the motor is connected with an eccentric wheel, an eccentric wheel shaft is eccentrically arranged on the eccentric wheel, a piston is arranged in the cylinder, the end of the piston is movably connected with the eccentric wheel shaft through a piston rod, and the buffer is respectively provided with an air inlet end and an exhaust end. Outside air enters the cylinder through the buffer, and noises in operation are reduced; air compressed out of the cylinder passes through the buffer so that the compressed air out of the cylinder is continuous and stable, and the problems that an air source of the medical nebulizer pump is discontinuous and air flow pulsation occurs are solved.
Description
Technical field
The utility model relates to a kind of medical apparatus, particularly a kind of medical atomizer pump.
Background technique
Medical atomizer commonly used in the medical treatment generally adopts the compression type reciprocating pump to come air feed.There is following shortcoming in the compression type reciprocating pump in the market: 1, because the structure problem of reciprocating pump often has lubricant oil to ooze out, pollute source of the gas; 2, air feed is discontinuous, causes gas; When 3, turning round bigger vibrations are arranged, noise is big.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of low noise medical treatment atomizer pump, reduces the running noise, and the source of the gas of continous-stable is provided.
In order to solve the problems of the technologies described above, low noise medical treatment atomizer pump of the present utility model, comprise cylinder, cylinder one side is connected with motor, and the cylinder block opposite side is equipped with cylinder head and buffer, and the rotating shaft of described motor is connected with eccentric wheel, off-centre is provided with eccentric shaft on this eccentric wheel, be provided with piston in the described cylinder, this pistons end flexibly connects by piston rod and described eccentric shaft, and the buffer both sides are respectively arranged with inlet end and exhaust end.
As improvement of the technical scheme, the described cylinder back side is equipped with the piston valve block, has on this piston valve block respectively and inlet end, suction valve and outlet valve that exhaust end is corresponding.
As improvement of the technical scheme, described cylinder back has heavy chamber, and described piston valve block is flush-mounted in this heavy chamber.
As improvement of the technical scheme, described piston rod and eccentric shaft contacting point are equipped with lubricating cup, have malthoid in this lubricating cup.Described motor rear end is equipped with radiation fan.
The beneficial effects of the utility model are: this low noise medical treatment atomizer pump is owing to adopted said structure, and outside air enters cylinder through buffer, reduces the running noise; From the feasible pressurized gas continous-stable that comes out from cylinder of air process buffer that cylinder compresses out, the source of the gas that has solved medical atomizer pump is discontinuous, the shortcoming of gas.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, low noise medical treatment atomizer pump of the present utility model, comprise cylinder 1, cylinder 1 one sides are connected with motor 2, and cylinder 1 opposite side is equipped with buffer 3, and the rotating shaft of described motor 2 is connected with eccentric wheel 4, off-centre is provided with eccentric shaft 5 on this eccentric wheel 4, be provided with piston 6 in the described cylinder 1, these piston 6 ends flexibly connect by piston rod 7 and described eccentric shaft 5, are respectively arranged with inlet end and exhaust end on the buffer 3.This low noise medical treatment atomizer pump is owing to adopted said structure, and outside air enters cylinder through buffer, reduces the running noise; From the feasible pressurized gas continous-stable that comes out from cylinder of air process buffer that cylinder compresses out, the source of the gas that has solved medical atomizer pump is discontinuous, the shortcoming of gas.
In the present embodiment, described cylinder 1 back is equipped with piston valve block 8, has on this piston valve block 8 respectively and inlet end, suction valve 9 and outlet valve 10 that exhaust end is corresponding.。Piston is driven by the piston rod that is installed on the motor when work, and eccentric wheel will become rotatablely moving of piston rod the to-and-fro motion of piston; When piston moves from right to left, form low pressure in the cylinder, outlet valve is discharged the pressure of inner air tube and is closed; Suction valve is subjected to the effect of low pressure in the cylinder and opens, and sucks air in the cylinder.When piston moved from left to right, because the cylinder inner air pressure increases, suction valve cut out, and piston is discharged the air of compression, forms the required pressurized air of compression atomizing device work.
Described cylinder 1 back has heavy chamber 11, and described piston valve block 8 is flush-mounted in this heavy chamber 11, and more compact structure is utilized to reduce small product size.
On the described piston rod 7 lubricating cup 12 is installed, has malthoid 13 in this lubricating cup 12, make piston rod and eccentric wheel contacting point obtain continuous lubrication, reduce friction, improve life of product.
Described motor 2 rear ends are equipped with radiation fan 14, and the heat that produces when being beneficial to product operation in time leaves, thereby stablize the long playing temperature rise of motor, and the protection inner body increases the service life.
The above only is preferential mode of execution of the present utility model, as long as realize that with basic identical means the technological scheme of the utility model purpose all belongs within the protection domain of the present utility model.
