Figure number and name: the air filter comprises an air inlet 1, an air guide pipe groove 2, a front shell 3, a filter material groove 4, a connecting column 5, an air guide pipe 6, a fan 7, a rear shell 8 and a connecting groove 9.

Detailed Description

The invention will be described in detail with reference to the drawings and specific embodiments, wherein the exemplary embodiments and descriptions are provided to explain the invention, but not to limit the invention.

As shown in fig. 1-2, the peripheral air intake type ventilator of the present invention comprises a front shell 3 and a rear shell 8 connected to each other, wherein an airway duct 2 is left on one side of the front shell 3 connected to the rear shell 8; an air inlet 1 is reserved on the side wall of the front shell 3, a connecting column 5 is fixedly arranged at the inner edge position, a filter material layer is fixedly arranged on the inner side wall through a filter material groove 4 in a buckling mode, the middle of the filter material layer is of a wave-shaped structure, the filter material layer is convenient to replace through the buckling mode, meanwhile, the middle of the filter material layer is of the wave-shaped structure, the contact area of the filter material layer and air can be increased, the filtering effect can be further increased, the air inlet 1 can be of any number and shape of rectangular, circular or other polygonal structures, and therefore air inlet efficiency and attractiveness of the breathing machine are improved;

a connecting groove 9 is fixedly arranged at the edge position inside the rear shell 8, a fan 7 is fixedly clamped inside the rear shell, the fan 7 is connected with an external power supply through a power supply interface and a power line, and the power supply interface is positioned on the rear shell 8;

the exit end block cover of fan 7 is equipped with

air duct

6, and 6 blocks of air duct are fixed to be set up on air duct groove 2, and the end of air duct 6 is connected with respirator through bellows, and bellows block is connected on air duct 6, and then when respirator uses, the air can loop through air intake 1, the precoat, fan 7, air duct 6 and bellows enter into respirator, and it is worth noting that, be provided with sealed the pad between air duct groove 2 and the air duct 6, can effectively increase the inside gas tightness of equipment, help improving air purification's efficiency, simultaneously the utility model discloses when indoor use, the end of air duct 6 still can directly expose in the air to the realization is to the purification of room air, can show the suitability that improves the breathing machine, provides a good living environment for the user.

The outer edge positions of the front shell 3 and the rear shell 8 are both of a round angle structure, so that the threat of the protruded edges of the front shell 3 and the rear shell 8 to personal safety can be effectively prevented, the safety and the reliability of equipment use are improved, the device is more humanized, and the use comfort is effectively improved.

Preceding shell 3 and backshell 8 are in the same place through spliced pole 5 and the mutual fixed connection of spread groove 9, spliced pole 5 and spread groove 9 adopt the fixed connected mode of block such as socket joint, buckle, magnetism to inhale, and then preceding shell 3 and backshell 8 of being convenient for separate, provide convenience for the filter material is changed and user's use.

The effective filtering area of the embodiment comprises the whole shell, so that the pressure drop of the respirator is very low, the corresponding energy consumption is also very low, and the consumption and the use cost of resources are reduced. In addition, because the inner side of the filter material has uniformly distributed negative pressure, the air inlet of the filter material is very uniform, the utilization rate of the filter material is high, the replacement frequency of the filter material is reduced, the use cost is reduced, and the purification effect is improved.

It should be noted that, in the present embodiment, the front shell 3 and the filter layer can be designed as an integral structure. When the filter material needs to be replaced, if the filter material is rigid, the filter material can be blown and cleaned through the air inlet 1 to realize the regeneration of the filter material. If the filter material is not easy to regenerate, the original filter material can be detached from the filter material tank 4 and replaced, or the whole front shell 3 can be directly replaced to realize the replacement operation of the filter material, and the operation is convenient.

The utility model discloses when using, at first will preceding shell 3 and backshell 8 accomplish the installation through spliced pole 5 and spread groove 9, secondly start fan 7, this breathing machine can normally work. When the fan 7 runs, strong negative pressure is generated at the inlet of the fan, and because the space between the filter material layer and the rear shell 8 is closed, the uniformly distributed negative pressure is formed at the inner side of the filter material layer, namely the side close to the inlet of the fan 7. Due to the action of pressure difference, gas firstly enters the breathing machine through the air inlet 1 and then uniformly passes through the filter material layer, particulate matters in the gas are intercepted by the filter material at the moment, the gas is purified and then is discharged from the outlet of the fan and enters the gas guide pipe 6. The end connection of air duct 6 has corrugated tube and respirator, and the gas through the purification gets into corrugated tube and finally sends into respirator and supply the user to breathe through air duct 6, and is same, and the end of air duct 6 also can directly expose in the air, and then reaches the purpose that realizes indoor air purification.

The utility model discloses in, side through shell 3 in the front sets up air intake 1 for inside the breathing machine got into the breathing machine at the air intake 1 of during operation side air, then evenly through the filter material layer, and then can effectively improve the result of use of filter material, reduce the change frequency of filter material, thereby reach reduction use cost, reduce the purpose of wasting of resources, simultaneously through distributing air intake 1 in the side of shell 3 in the front of setting, greatly increased the aesthetic property of this breathing machine. In addition, because the front shell 3 and the rear shell 8 are all complete shells, patterns such as animation, cartoons, games, scenery, characters, starry sky and the like can be printed on the front shell 3 and the rear shell 8 respectively, so that the whole breathing machine is more attractive, and the use comfort of a user can be effectively improved.
