Description

Technical Field

[0001] The utility model relates to the technical field of passive houses, in particular to a ventilation and filtering device for a passive house. Background Art

[0002] Passive house is a new energy-saving building concept advocated by foreign countries. It is also an important opportunity and platform for my country to promote building energy conservation. It is an integrator of various technical products. By making full use of renewable energy, the total amount of all disposable energy consumed does not exceed 120 kWh of the house.

[0003] Passive houses are equipped with ventilation ducts to ventilate the interior, but since the external environment contains a lot of dust and impurities that need to be cleaned, the filter needs to be disassembled and cleaned after a period of use. However, when the existing filter is disassembled, the dust on the outer wall can easily fall into the inside of the ventilation duct, causing dust to enter the house. In view of this, we need a passive house ventilation filtration device. Utility Model Content

[0004] The purpose of the utility model is to provide a passive room ventilation and filtering device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a passive room ventilation and filtering device, comprising a house, a ventilation duct is arranged on the house, a groove is opened on the side wall of the ventilation duct, a filtering mechanism is arranged above the ventilation duct, a mounting mechanism is arranged on the ventilation duct, and the filtering mechanism includes:

[0013] Compared with the prior art, the utility model provides a passive room ventilation and filtration device, which has the following beneficial effects:

[0014] 1. The passive room ventilation filter device can make the two sets of plates move backwards out of the fixed frame through the elastic force of the bearing spring in the filter mechanism, so that the middle filter can filter the internal air of the ventilation duct. At the same time, during the disassembly process, the two sets of plates move towards each other to block the middle filter, which can prevent the dust on the filter from falling into the ventilation duct.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a passive house ventilation and filtering device, comprising a house 1, a ventilation duct 2 is arranged on the house 1, a groove 3 is opened on the side wall of the ventilation duct 2, a filtering mechanism 4 is arranged above the ventilation duct 2, and a mounting mechanism 5 is arranged on the ventilation duct 2.

[0022] In this embodiment, a filtering mechanism 4 is provided above the ventilation duct 2. The elastic force of the supporting spring 44 in the filtering mechanism 4 can enable the two sets of plates 45 to move backwards out of the interior of the fixed frame 41, so that the middle filter 42 can filter the internal air of the ventilation duct 2. At the same time, during the disassembly process, the two sets of plates 45 can move towards each other to block the middle filter 42, so as to prevent dust on the filter 42 from falling into the interior of the ventilation duct 2.

[0023] In this embodiment, an installation mechanism 5 is provided on the ventilation duct 2. The limit can be released by squeezing the bottom arc surface of the block 52 in the installation mechanism 5 by the fixed block 53, so that the block 52 can be conveniently inserted into the interior of the slot 54 to complete the installation. At the same time, the limit of the block 52 can be released by pushing the elastic plate 51, so that disassembly is convenient.

[0024] The above-mentioned filtering mechanism 4 includes a fixed frame 41, which is arranged above the ventilation duct 2. A filter screen 42 is fixedly installed on the inner wall of the fixed frame 41, a fixed plate 43 is fixedly installed on the inner wall of the fixed frame 41, and a load-bearing spring 44 is fixedly installed on the outer wall of the fixed plate 43. The elastic force of the load-bearing spring 44 can make the two sets of plates 45 move back to the inside of the fixed frame 41, so that the middle filter screen 42 can filter the internal air of the ventilation duct 2. The end of the load-bearing spring 44 is fixedly installed with a sleeve plate 45. The sleeve plates 45 on both sides of the fixed frame 41 are pushed into the inside of the fixed frame 41 for easy installation. The sleeve plates 45 are arranged in an inclined shape. The inclined surface of the sleeve plates 45 is squeezed by the groove 3, so that the two sets of plates 45 can move towards each other to block the middle filter screen 42, thereby preventing dust on the filter screen 42 from falling into the inside of the ventilation duct 2. The sleeve plates 45 are fixedly connected to the inner wall of the fixed frame 41, and the sleeve plates 45 are sleeved on the outside of the filter screen 42.

[0025] The above-mentioned installation mechanism 5 includes an elastic plate 51, which is fixedly installed on the outer wall of the fixed frame 41. A clamping block 52 is fixedly installed on the outer wall of the elastic plate 51. The elastic force of the elastic plate 51 can make the clamping block 52 clamped into the inside of the clamping groove 54 for easy installation. The bottom wall of the clamping block 52 is set to an arc shape. The bottom arc surface of the clamping block 52 is squeezed by the fixed block 53, which can make the clamping block 52 drive the elastic plate 51 to deform so that the limit is released, which is convenient for clamping. A fixing block 53 is fixedly installed on the outer wall of the ventilation duct 2, and a clamping groove 54 is opened on the fixing block 53, and the clamping groove 54 is located at the bottom of the clamping block 52.

[0026] In this embodiment, during use, the sleeve plates 45 on both sides of the fixed frame 41 are first pushed into the fixed frame 41, and then the internal filter screen 42 is installed in the ventilation duct 2 by pushing the fixed frame 41 downward. During the installation process, the fixing frame 41 drives the block 52 on the outer wall of the elastic plate 51 to move downward, and the curved surface at the bottom of the block 52 is squeezed by the fixed block 53, so that the block 52 drives the elastic plate 51 to deform and the limit is released. Finally, the elastic force of the elastic plate 51 is used to make the block 52 snap into the inside of the slot 54 to complete the installation. At this time, the elastic force of the bearing spring 44 makes the two sleeve plates 4 5 moves backward, and then the sleeve plate 45 moves out of the interior of the fixed frame 41 through the opening of the groove 3, so that the middle filter screen 42 can filter the internal air of the ventilation duct 2. When the filter screen 42 needs to be disassembled and cleaned, the clamping block 52 is released from the limit by pushing the elastic plate 51, and then the fixed frame 41 is pulled upward to move upward. At this time, the inclined surface of the sleeve plate 45 is squeezed by the groove 3, so that the two sleeve plates 45 move towards each other, and then the middle filter screen 42 is blocked to prevent dust on the filter screen 42 from falling into the interior of the ventilation duct 2, and finally the cleaning work of the filter screen 42 is completed.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
