Description

Technical Field

[0001] The utility model relates to the technical field related to ventilation systems, in particular to a green building energy-saving ventilation system. Background Art

[0002] Ventilation is a building environment control technology that uses air exchange to dilute pollutants in the air and ensure the quality of indoor and outdoor air environments. General ventilation systems directly introduce air into the room when in use, causing dust and harmful substances in the air to directly enter the room, thereby reducing the ventilation effect. Therefore, there are certain shortcomings.

[0003] For example, an energy-saving ventilation system with publication number CN218237707U filters the air in the pipe through a filter so that the dust is located on one side of the filter. When cleaning the dust, pull the handle on one side of the connecting plate to make the connecting plate drive the movable plate to slide inside the pipe. At the same time, the slide plate slides on one side of the positioning plate to increase the distance between the connecting plate and the pipe until the movable plate is located outside the pipe. At this time, the filter can be cleaned. After cleaning, the movable plate is pushed into the pipe so that the connecting plate is located on one side of the pipe. The connecting plate can be fixed. The structure is simple and easy to operate.

[0004] The above-mentioned prior art has the following technical problems: the existing ventilation system filters the air through the filter and then passes it into the room when in use, but due to the accumulation of dust on one side of the filter during long-term use, the ventilation effect will gradually decrease, and when the air temperature is high, the filter with a large amount of dust will easily absorb heat, thereby passing hot air into the room, reducing the energy-saving and environmental protection effect.

[0005] So we proposed a green building energy-saving ventilation system to solve the problems raised above. Utility Model Content

[0006] The utility model aims to provide a green building energy-saving ventilation system to solve the problem raised by the above-mentioned background technology that the existing ventilation system on the market at present filters the air through a filter screen before passing it into the room during use, but due to the accumulation of dust on one side of the filter screen during long-term use, the ventilation effect will be gradually reduced, and when the air temperature is high, the filter screen with a large amount of dust will easily absorb heat, thereby passing hot air into the room, reducing the energy-saving and environmental protection effect.

[0007] To achieve the above object, the utility model provides the following technical solutions: a green building energy-saving ventilation system, comprising a ventilation box, the upper right end of the ventilation box is connected to a working box by fastening bolts, and a pump is fixedly installed on the right end of the working box, and the lower right end of the ventilation box is fixedly connected to an air inlet channel, and a connecting pipe is fixedly installed on the upper end of the air inlet channel;

[0008] Also includes:

[0009] The water inlet pipe is connected to the upper end of the working box, and the water outlet pipe is fixedly installed at the lower end of the air inlet channel, and the inner wall of the air inlet channel is fixedly connected to a heat absorbing member, and a cavity is opened inside the air inlet channel;

[0010] The rotating rod is rotatably mounted on the inner wall of the working box, and the tail end of the rotating rod is fixedly connected with an impeller, and the head end of the rotating rod is fixedly installed with a ventilation fan, and the outer wall of the rotating rod is nested with a brush rod, and a filter is slidably arranged in a groove opened on the inner wall of the working box;

[0011] The rear end of the baffle is slidably connected to a groove opened at the rear end of the air inlet channel, and a return spring is fixedly connected to the rear end of the baffle.

[0012] Preferably, the pump input end is connected to the lower end of the water tank through a pumping pipe, and the water outlet pipe is connected to the upper end of the water tank.

[0013] Preferably, the raised outer walls at both ends of the filter element fit with the inner wall of the groove opened inside the working box, and the surface of the filter element is provided with mesh openings distributed in an array.

[0014] Preferably, evenly distributed brushes are fixedly connected to one side of the brush rod close to the filter element, and the brushes on the filter element fit the surface of the filter element.

[0015] Preferably, the lower end of the connecting pipe is connected to the upper end of the cavity, and the lower end of the cavity is connected to the tail end of the water outlet pipe.

[0016] Preferably, the heat absorbing element and the cavity are both arranged in a cylindrical shape, and the heat absorbing element is made of silicon dioxide.

[0017] Preferably, the rear end of the return spring is fixedly connected to the bottom of a groove opened at the rear end of the air inlet channel, and a rubber pad is fixedly bonded to one side of the baffle plate close to the air inlet channel.

[0018] Compared with the prior art, the beneficial effects of the utility model are: the green building energy-saving ventilation system can clean the dust on the filter surface while using the ventilation system through the cleaning component, thereby ensuring the reliability of the long-term operation of the ventilation system, and the hot air is cooled and introduced into the room through the heat absorption component, thereby improving the energy-saving and environmental protection effect. The specific contents are as follows:

[0019] 1. An impeller is provided. When in use, the pump is first started to draw water from the water tank through the water suction pipe, and then the water is passed into the working box through the water inlet pipe. The water pressure impacts the blades of the impeller, and then the impeller drives the rotating rod to rotate, so that the rotating rod drives the ventilation fan at the head end to ventilate;

[0020] 2. A filter is provided. When the ventilation fan draws the outside air into the room, the air passes through the evenly distributed mesh openings on the surface of the filter, blocking the dust in the air and preventing the dust from entering the room and affecting the indoor air quality.

[0021] 3. A brush rod is provided. When the filter element is used for a long time to block the dust in the air, a large amount of dust will adhere to the surface of the filter element, thereby reducing the air filtering effect of the filter element. Therefore, while the impeller drives the rotating rod to rotate, a brush evenly distributed on the side of the brush rod close to the filter element is provided. The brush will brush off the dust blocking the mesh of the filter element, thereby ensuring the long-term use effect of the filter element;

[0022] 4. A cavity and a heat-absorbing component are provided. After water enters the working box through the water inlet pipe, the water flows through the connecting pipe to the cavity opened in the air inlet channel. Since the inner wall of the air inlet channel is provided with a heat-absorbing component made of silica material with a strong heat-absorbing effect, when the hot air passes through the air inlet channel, the heat-absorbing component absorbs the heat of the hot air and transfers it to the water in the cavity for absorption, thereby improving the effect of energy saving and environmental protection;

[0023] 5. A baffle is provided. When the weather is too hot or too cold, first pull the handle on the outside of the baffle to make the tail end of the baffle slide in the groove opened at the tail end of the air inlet channel, and at the same time stretch the reset spring, then rotate the baffle to align with the tail end of the air inlet channel, and then let go to allow the reset spring to drive the baffle to reset, so that the rubber pad on the inside of the baffle blocks the air inlet at the tail end of the air inlet channel, thereby achieving energy saving and environmental protection.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Example 1: Please refer to Figure 4 and Figure 6 The utility model provides the following technical solutions. The existing ventilation system will be attached with a lot of dust after long-term use due to the filter screen set, thereby reducing the ventilation effect. In order to solve this technical problem, the present embodiment discloses the following technical contents: a green building energy-saving ventilation system, including a ventilation box 1, the upper right end of the ventilation box 1 is connected with a working box 2 by fastening bolts, and the right end of the working box 2 is fixedly installed with a pump 3, and the lower right end of the ventilation box 1 is fixedly connected with an air inlet channel 5, and the upper end of the air inlet channel 5 is fixedly installed with a connecting pipe 6;

[0033] During long-term use, a large amount of dust will adhere to the surface of the filter element 11, reducing the air filtering effect of the filter element 11. Starting the pump 3 allows the impeller 8 to drive the rotating rod 9 to rotate through the water flow. The brush rod 10 on the outer wall of the rotating rod 9 close to the filter element 11 will brush off the dust on the surface of the filter element 11 to ensure the long-term use effect of the filter element 11.

[0034] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. By setting a cleaning component, the filter screen is cleaned during the indoor ventilation process, and the heat absorption component is set to ensure the reliability of the long-term operation of the ventilation system. Figure 1-Figure 2 , Figure 4 and Figure 6As shown, the water inlet pipe 4 is connected to the upper end of the working box 2, and the water outlet pipe 7 is fixedly installed at the lower end of the air inlet channel 5, and the heat absorber 13 is fixedly connected to the inner wall of the air inlet channel 5, and a cavity 51 is opened inside the air inlet channel 5; the rotating rod 9 is rotatably installed on the inner wall of the working box 2, and the impeller 8 is fixedly connected to the tail end of the rotating rod 9, and the ventilation fan 12 is fixedly installed at the head end of the rotating rod 9, and the brush rod 10 is nested and connected to the outer wall of the rotating rod 9, and the filter 11 is slidably arranged in the groove opened in the inner wall of the working box 2; the input end of the pump 3 is connected to the lower end of the water tank through the water pumping pipe, and the water outlet pipe 7 is connected to the upper end of the water tank. The raised outer walls at both ends of the filter 11 fit with the inner wall of the groove opened inside the working box 2, and the surface of the filter 11 is provided with mesh openings distributed in an array. The brush rod 10 is fixedly connected to the side close to the filter 11 with evenly distributed brushes, and the brush on the filter 11 fits with the surface of the filter 11. The lower end of the connecting pipe 6 is connected to the upper end of the cavity 51, and the lower end of the cavity 51 is connected to the tail end of the water outlet pipe 7. The heat absorbing member 13 and the cavity 51 are both cylindrical, and the heat absorbing member 13 is made of silicon dioxide.

[0035] When in use, first start the pump 3, so that the pump 3 draws water from the water tank through the suction pipe, and then passes it into the working box 2 through the water inlet pipe 4. Due to the impact of water pressure on the blades of the impeller 8, the impeller 8 drives the rotating rod 9 to rotate, so that the rotating rod 9 drives the ventilation fan 12 at the head end to ventilate. When the ventilation fan 12 draws external air into the room, the air passes through the evenly distributed mesh ports set on the surface of the filter element 11, and the dust in the air is blocked to prevent dust from entering the room and affecting the indoor air quality. When the filter element 11 is used for a long time to block the dust in the air, a large amount of dust will adhere to the surface of the filter element 11, thereby reducing the filtration effect. In order to improve the effect of the filter element 11 on air filtering, while the impeller 8 drives the rotating rod 9 to rotate, a brush evenly distributed on the side of the brush rod 10 close to the filter element 11 is provided, and the brush brushes off the dust blocking the mesh port of the filter element 11, thereby ensuring the long-term use effect of the filter element 11. After water enters the working box 2 through the water inlet pipe 4, the water flows through the connecting pipe 6 to reach the cavity 51 opened in the air inlet channel 5, and because the inner wall of the air inlet channel 5 is provided with a heat absorbing element 13 made of silica with a strong heat absorption effect, when the hot air passes through the air inlet channel 5, the heat absorbing element 13 absorbs the heat of the hot air and transfers it to the water in the cavity 51 for absorption, thereby improving the effect of energy saving and environmental protection.

[0036] Embodiment 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiments 1 and 2. By setting a shielding structure, the vents are blocked when not in use to prevent the exchange of external air with the indoor air, thereby achieving energy saving and environmental protection. Figure 1-Figure 3 and Figure 5As shown, the tail end of the baffle 14 is slidably connected to the groove opened at the tail end of the air inlet channel 5, and the tail end of the baffle 14 is fixedly connected to a return spring 15. The tail end of the return spring 15 is fixedly connected to the bottom of the groove opened at the tail end of the air inlet channel 5, and a rubber pad is fixedly bonded to one side of the baffle 14 close to the air inlet channel 5.

[0037] When not in use, first pull the handle on the outside of the baffle 14 so that the rear end of the baffle 14 slides in the groove opened at the rear end of the air inlet channel 5, and at the same time stretches the reset spring 15, and then rotates the baffle 14 to align with the rear end of the air inlet channel 5, and then releases the handle so that the reset spring 15 drives the baffle 14 to reset, so that the rubber pad on the inside of the baffle 14 blocks the air inlet at the rear end of the air inlet channel 5, preventing the outside air from exchanging with the indoor air, thereby achieving the effect of energy saving and environmental protection.
