Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to a fume hood for purifying community fume. Background Art

[0002] The existing range hood uses a transfer method to process the oil fume, specifically, the oil fume in the kitchen is sent out through the exhaust pipe. In the actual use process, because the high-rise buildings in the city now use a public flue, in the same period of time, there are often multiple users exhausting smoke into the flue, which makes the air pressure in the flue relatively high, affecting the exhaust of oil fume. The "a kind of fume hood with oil fume purification function" disclosed by the application number "CN201420834545.8" solves the problem that the public flue in the high-rise building will cause the air pressure in the flue to be relatively high when multiple users exhaust smoke, which affects the exhaust of oil fume through a specific technical structure setting, but there are still many defects in actual use, such as: the fan and the exhaust pipe installed in the chassis will generate a lot of noise. When the device is installed in the community, such as in the storefront, it will cause physical and mental effects on the people in the community. Some will wrap sound-absorbing cotton on the pipe, but the noise generated by the fan cannot be handled. Utility Model Content

[0003] The purpose of the utility model is to provide a fume hood for purifying community fume, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fume hood for community oil fume purification, comprising a fume collecting hood, an inner shell and an outer shell, the outer shell being fixed in the middle of the outer top surface of the fume collecting hood, the inner shell being arranged inside the outer shell, the outer bottom end of the inner shell being connected to a first pipe, the bottom end of the first pipe being connected to a cigarette head, and the cigarette head being fixed in the middle of the inner part of the fume collecting hood, the outer top end of the inner shell being connected to a second pipe, the outer surface of the second pipe being wrapped with a second sound-absorbing cotton, and the second sound-absorbing cotton being fixed to the outer surface of the second pipe by a clamp.

[0005] When using a fume hood for community fume purification in the technical solution, it is necessary to first connect an external power supply to the utility model, control the operation of the utility model through a switch, and the user controls the operation of the motor. The motor rotates the impeller connected to the output end, and after the impeller rotates, negative pressure suction is generated in the first pipe and the smoking head. The negative pressure suction will suck the smoke generated by the cooking stove at the bottom of the smoke hood into the inside, and transmit it to the inside of the second pipe through the rotating impeller, and finally the smoke is transmitted and discharged by the second pipe. The noise generated when the smoke is transmitted in the second pipe will be reflected by the second pipe wrapped by the outer surface. The noise generated by the motor itself and the rotating impeller will be absorbed by the first sound-absorbing cotton, and the noise generated by the motor itself and the rotating impeller will be absorbed by the first sound-absorbing cotton, reducing the impact of noise on people in the community. When the first sound-absorbing cotton and the second sound-absorbing cotton need to be replaced after being used for a certain period of time, the user directly takes the tool to twist and release the lock of the clamp, removes the wrapped second sound-absorbing cotton from the outer surface of the second pipe, and then replaces it with a new one and fixes it with a clamp, rotates the clamp rod to release the limit fixation of the baffle, rotates the baffle after releasing it, removes the first sound-absorbing cotton wrapped on the outer surface of the inner shell, and replaces it with a new one for subsequent use.

[0006] Preferably, a motor is fixed to one side of the inner shell, an impeller is fixed to the output end of the motor, and the impeller is arranged on the other side of the inner shell. Through the cooperation of the motor and the impeller, negative pressure suction can be generated in the first pipe and the smoking head, achieving the effect of generating negative pressure suction to suck in and transmit oil smoke.

[0007] Preferably, the outer surface of the inner shell is wrapped with a first sound-absorbing cotton. The first sound-absorbing cotton can absorb the noise generated by the motor itself and the noise generated by the rotation of the impeller, thereby achieving the effect of reducing noise.

[0008] Preferably, a baffle is rotatably mounted on the outer front surface of the housing through a hinge, and a clamp is provided at one end of the baffle. The installation of the clamp allows the baffle to be fixed and closed to prevent the baffle from automatically opening without manual force, and the installation of the baffle allows the user to operate the device installed inside the housing through this position, providing an operating position.

[0009] Preferably, a switch is provided in the middle of the outer front surface of the smoke collecting hood. The provision of the switch makes the utility model easy to be controlled and operated by the user.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. By rotating and installing the baffle on the outer front surface of the outer shell, the first sound-absorbing cotton can be wrapped on the outer surface of the inner shell after opening the baffle, which is convenient for early installation and later disassembly and replacement. The first sound-absorbing cotton can absorb the noise generated by the motor and impeller installed inside the inner shell, reduce noise emission, and protect the physical and mental health of people in the community.
