Abstract
The utility model relates to a sound insulation, dust filtering ventilation device, which comprises a power mechanism which provides power for the utility model. The utility model is characterized in that a piston cavity is arranged in a machine body with a box-shaped structure, and a piston which is driven by the power mechanism is installed in the piston cavity. One end of the piston cavity is provided with a gas suction port, and the other end of the piston cavity is provided with a gas extrusion port and an external gas inlet port. The gas extrusion port and the external gas inlet port are both provided with one-way valves, and a liquid box which is used for gas filtration is arranged between the gas suction port and the gas inlet port of the piston cavity. The piston is driven by making use of the power mechanism to move towards left and towards right to realize the mandatory permutation of indoor gas and outdoor gas, and gas which enters is filtered by a liquid box which is arranged between a gas inlet pipe and the gas suction port and of the piston cavity. In addition, the liquid box which is arranged has the function of sound insulation simultaneously.
Description
Technical field
The utility model relates to air interchanger, especially a kind of sound insulation, filter dirt air interchanger.
Technical background
Along with the large-scale development of modern city, overlooking and high buildings and large mansions that build play an important role for the city prosperity.But noise that motor vehicles sent that travels in the street and the dust of kicking up are but given life or are operated in the interior people of these overlooking buildings and caused harmful effect.People, can only close overlooking window the pollution of room air for fear of the interference of these noises and dust.This can cause the room air circulation not smooth undoubtedly, lives in this airtight relatively space or work, is unfavorable for the health of human body.At present, in order to address the above problem, normally in room at the front, ventilation fan is installed.The effect of ventilation fan is the displacement that realizes indoor-outdoor air by forward and reverse running.But it there is no the function of sound insulation and filter dirt.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned existence, and a kind of indoor-outdoor air displacement that both can realize is provided, and has sound insulation, the filter dirt air interchanger of sound insulation filter dirt function again.
The utility model sound insulation, filter dirt air interchanger, comprise: the actuating unit that power is provided for this device, it is characterized in that: be provided with plunger shaft in the body of a box structure, install one in the plunger shaft by the actuating unit drive piston, one end of plunger shaft is provided with the gas suction inlet, the other end of plunger shaft is provided with gas and extrudes mouth and inner air inlet, and described gas extrudes mouth and inner air inlet is equipped with check valve; Be provided with the fluid box that is used for gas filtration between plunger shaft gas suction inlet and the air inlet pipe.
The design principle of the utility model sound insulation, filter dirt air interchanger is, utilize the side-to-side movement of actuating unit driven plunger in plunger shaft to realize the mandatory displacement of indoor and outdoor gas, and by being arranged on the gas filtration of fluid box between air inlet pipe and plunger shaft gas suction inlet to entering, the filtration of described gas both can be removed the grit that contains in the gas, the effect of Purge gas has the effect of sound insulation simultaneously.
The utility model sound insulation, filter dirt air interchanger design science, rational in infrastructure, simple, have easy to use, advantage such as ventilation effect is good.
The concrete structure of the utility model sound insulation, filter dirt air interchanger is provided in detail by the following drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of sound insulation, filter dirt air interchanger.
The specific embodiment
Embodiment: can be clear that from Fig. 1, sound insulation, filter dirt air interchanger have the body 1 of a box structure, be provided with plunger shaft 2 in the body 1, one piston 4 by actuating unit 3 drivings is installed in the plunger shaft 2, one end of plunger shaft 2 is provided with gas suction inlet 5, the other end of plunger shaft 2 is provided with clean gas and extrudes mouth 6 and inner air inlet 7, gas suction inlet 5 communicates with inner air inlet 7 and fluid box 9 top vent 10 by passage 8, and described clean gas extrudes mouth 6 and inner air inlet 7 is equipped with check valve 11,12; Described fluid box 9 is arranged in the body 1, and fluid box 9 is provided with one can insert the air inlet pipe 13 of its liquid level below.
The using method and the course of work of sound insulation, filter dirt air interchanger: this device is installed on body of wall or the windowsill, air inlet pipe 13 mouths of pipe of device outwardly, clean gas extrudes mouthfuls 6 towards indoor.Drive piston 4 side-to-side movement in plunger shaft 2 in the body 1 during actuating unit 3 operations, 2 two spaces of plunger shaft of being separated by piston 4 change along with the motion of piston 4, when piston 4 during to left movement, gas in the 2 left chambeies, piston 4 left hand piston chambeies is compressed, this Compressed Gas is closed the check valve 12 that is arranged on inner air inlet 7, make and be arranged on check valve 11 unlatchings that clean gas extrudes mouth 6, compressed gas can only extrude mouth 6 from clean gas and enter indoor, when piston 4 moves from left to right, owing to reducing to make outdoor air, the air pressure in the plunger shaft 2 after air inlet pipe 13, passes through fluid box 9 admission passages 8, because the check valve 11 that extraneous pressure makes clean gas extrude mouth 6 is closed, the gas that imports from air inlet pipe 13 can only enter plunger shaft 2 left chambeies by passage 8 and inner air inlet 7.When piston 4 moves next time, will repeat above process, thereby reach the purpose that indoor and outdoor gas forces displacement.Because the air that imports from air inlet pipe must pass through fluid box, contain grit in the air through after liquid filtering is purified, the plunger shaft 2 of being allowed for access, therefore, it is clean entering indoor gas by clean gas extrusion mouth 6, and set fluid box 9 has the function of sound insulation simultaneously.
