detailed description

Specific embodiments of the structure and detection method of the air purifier of the present invention will be further described with reference to the accompanying drawings.

First of all, it should be noted that the positive pressure and the negative pressure referred to in the text refer to the pressures above or below the normal atmospheric pressure in the room, respectively. The first and second embodiments have many air inlets, air outlets, air inlets, and exhaust outlets. Perforated cavities, which are removably mounted on the ports of the duct.

Generally speaking, the air purifier used in the home can be selected from plants cultivated in a container that can be easily moved or plants that are cultivated in a fixed place. For a single cultivated container, multiple factors such as the influence of light and differences in photosynthesis of plants must be considered comprehensively, and its minimum area should at least meet the breathing needs of an adult. Running air purifier, the exhaust port on the interior C0 ₂ exhaled by the user more places, in the vicinity of the air inlet to the user needs to breathe. For users who are close to reading and chatting, the air duct of the machine can be short. The exhaust port and air supply port on the base have multiple openings that can be used by several people. Each opening has an adjusted position and direction and Structure that pushes in and out. For users who are far away, multiple short flexible air ducts can be extended in sections. To prevent the air inlet and exhaust port from being reversed when the air duct is disassembled, two air ducts connected to the air outlet and the air exhaust port will be connected. The male and female threads of the Luokou at the continuation are arranged in opposite directions, and the outer surface of the air duct and the fan may be marked with an arrow mark indicating the direction. For indoor users who are relatively still, the exhaust port and air supply port are movably placed near the user. Because the dirty air contains more C0 ₂ , its specific gravity is greater than that of purified gas containing 0 ₂ , so it provides purification. The air supply port of the gas should be higher than the exhaust port. If the air port is provided with purified air to the user from the nose and nose, the exhaust port is placed below the nose and nose. The upward air hole depends on the wind. The negative pressure of the machine absorbs the gas exhaled by the user. For sleeping or substantially immobile users, the length is preferably greater than the head width and smaller than the shoulder width. 3 米 / 秒。 In order to avoid the air blowing directly on the head, the height and direction of the air inlet are adjustable, for health, the exhaust port, air inlet should not generate air velocity around 0.3 m / second. Tests show that each person's actual breathing volume is about 5-7. 5 liters / min. A low wind speed and low power fan that matches the breathing volume can be used, and then a light emitting diode (hereinafter referred to as LED) light source is used to reduce energy consumption. . In order to reduce air debris, the filter bag is covered outside the exhaust air inlet, air inlet, air inlet and air outlet of the inhaled gas, or the filter is clamped in the air flow path. The present invention can select a semi-automatic watering method, that is, a water pump with adjustable flow rate can be used. The user can adjust the number of days between watering and the time (second) of each watering of the air purifier. After the above parameters are manually set, You can achieve watering work once every few days and completed automatically each time. As shown in FIG. 1, the air purifier of the present invention has a photosynthetic plant 11; a cultivation container 13 for cultivating the plant; a water supply system for watering; air pipes 155 and 156 for air exchange; A fan 16 in the frame; a frame 17 for receiving and connecting machine parts and a support frame 18 coupled to the frame; a hanging piece 14 connected to a hanger 19 on the support frame, and a light source 12 hanging on the foliage of the plant 11 Up. Its working principle is: under the action of the fan 16, the exhaust port 151 at the end of the air pipe 155 sucks in the gas exhaled near the user, and is blown to the leaves of the plant 11 by the air supply port 152 at the other end of the air pipe, at least including the plant The light source 12 of red and blue light waves required for photosynthesis is placed above the leaf surface of the plant, and the purified air is sucked in by the air outlet 154 of another air duct 156 which is opposite to the air outlet 152 and close to The user has a positive-pressure reversible air supply port 153 provided to the user. The distance between the light source 12 and the leaf surface of the plant 11 can be changed by adjusting the height of the hanger 19 or the length of the suspension 14. The exhaust port 151 can be pushed inward and outward along the air duct 155 sleeved on the outside. To adjust the exposed length of the exhaust port 151, of course, the exhaust port and the air supply port can also be made into a flexible structure that can rotate. Arrow 177 in the figure is the direction of the air flow. For industry For chemical production, the plants 11 can be pre-made into turf matching the shape of the cultivation container 13 before cultivation. The size of the water flow in the water tank 142 is poured into the cultivation container 13 by the adjustable-flow water pump 143 through the water supply pipe 141 and the drip pipe 146. After the flow rate of the water pump 143 is adjusted, the time interval for each watering, The length of time is set by an adjustable time controller.

In order to renew the air, the exhaled air can also be exhausted to the outside through the outdoor exhaust pipe; outdoor air is provided to the breather through the outdoor air intake pipe, and these pipes are used with the air supply pipe and exhaust pipe of the air purifier. The on-off valve is connected to adjust the indoor and outdoor gas mixing ratio. In FIGS. 1A and IB, the connection of the fan 16 of FIG. 1 with the exhaust port 154 and the air supply port 152 is disconnected and an adjustable three-way valve 101 and 102 are added respectively. The common ends 164 and 167 of the fan 16 are connected to the fan 16, The two branch pipes 165 and 166 of the three-way valve 101 are connected to the exhaust port 154 and the outdoor air inlet pipe 161, respectively. The regulating valve 163 can adjust or close the air supplied to the user by the outdoor air inlet pipe 161 and 154 from Purifier gas ratio. The two branch pipes 169, 170 of the three-way valve 102 are connected to the air outlet 152 and the outdoor exhaust pipe 162, respectively. The regulating valve 168 can adjust or close the outdoor exhaust pipe 162 or the exhaust pipe as required. Purifier exhaust ratio. Arrow 177 in the figure indicates the direction of air flow.

In order to solve the problem of heat dissipation, the present invention uses a thermally conductive connector connected to the electrical radiator of the air purifier to take away heat. There are various ways to take away the heat. The connector can be connected to the airflow generated by the fan, and Connect the thermal connector to the water tank body or water in the water tank of the thermally conductive material.

In FIG. 1C, one of the air ducts 155 in FIG. 1 is disconnected and a special heat-conducting air duct 112 is added, and the other end of the heat-conducting connection plate 111 (the two constitutes a heat-conducting connector) connected to the air cleaner generates heat. The radiators of electrical appliances (such as transformers, rectifier regulators) are connected, and the conducted heat is carried away by the airflow in the air duct 155. In FIG. 1D, the water tank 142 has a thermally conductive connection plate 111 (if the tank is a thermally conductive material, The heat-conducting connection plate 111 can be directly connected to the tank body), through which the heat of the heating appliance can be transferred to the water.

In order to meet the requirements of different living rooms, people, and purification methods, multiple cultivation containers can be assembled, and the assembly method is a single-layer plane or a multi-layer three-dimensional structure. In addition to the aforementioned single-container method, multiple containers can be used in series "Way, now with two containers

"Tandem" is taken as an example. C4 plants with strong photosynthesis and oxygenation, such as matang and ground brocade, are cultivated in the first cultivation container, and algae and spider plant, which are strong in adsorbing harmful gases in the root system, are cultivated in the second. In each cultivation container, when the air purifier is operating, the exhaust port of a duct of the first cultivation container is placed below the user's mouth and nose to inhale human exhaled air, and then sent to the plant leaves from the air supply port of the duct ; The purified air is sucked into the air outlet of another air duct near the plant, and the air duct extends to the other end of the second container, and is connected to the air supply port buried in the cultivation medium, which sends the air to Plant roots; Because the cultivation medium selected vermiculite, rice husk, fiber cotton and other materials with high water absorption and good air permeability, the adsorption of plant roots was improved, and the air absorbed by the roots was taken by another wind from the second container. The air outlet of the tube is sucked in, and sent to the user's breathing place through the air inlet of the other end of the air tube. In this way, the leaves of the first cultivation container plant increase the air by 0 ₂ and reduce C0 ₂ , and the second cultivation container plant Adsorption and roots growing medium reduces the content of harmful gases and carbon monoxide, formaldehyde. Although the above is just an example of using two cultivation containers in series, the principle is also suitable for more combinations of containers.

In FIG. 2, an exhaust port 251 of an air duct 261 near the user end, under the action of the fan 16, it sucks in more air of C0 ₂ exhaled by the user through the air supply port 252 at the other end of the air duct 261 and sends it to The leaves of the photosynthetic stronger plant 211 in the cultivation container 213. After the plant is irradiated by the light source 22, the air is sucked into the exhaust port 253 disposed opposite the air supply port 252, and the air pipe 262 sends the air to the The tuyere 254 is buried in the soft air-permeable medium 268 in the cultivation container 214 through which the tuyere 254 is buried. The air absorbed by the root system of the stronger plant 221 is sucked into the air outlet 255 of the air pipe 263, and is sent to the user's breathing place through the air inlet 256 of the other end of the air pipe 263, 265, and 264 connected to it. The tube 264 can rotate along the rotation axis 266 and move the air supply port 256 to change its position with the user. The power of the fan 16 is reasonably selected, such as its power is 1-5 watts, so that the air flow that contacts the human body meets the breathing needs and the speed is less than 0.3 m / s. In this embodiment, for users who are far away, the air ducts 261 and 264 can be extended by a plurality of short air ducts in sections. The air outlets 253 and 255, the air supply ports 252 and 254, the air outlets 251, and the air supply ports 256. It is detachably installed on the air pipe connected to it. The structure of the connection to prevent the wrong connection of the air pipe is shown in Figures 2B-1 and 2B-2. The filter made of breathable and filtering fabric in the figure The bag 285 can be covered outside the exhaust port 251, and the elastic bag port 286 plays a fixed role, and other exhaust ports and exhaust ports can also be equipped with similar filter bags. In the figure, the air supply port 256 is provided with a male thread 287, and the exhaust port 251 is provided with a female thread 288. The air pipes 264 and 261 connected to the air port 256 are provided with female and male ribs, respectively. This structure can prevent misconnection. For easy identification, the fan and duct may be marked with an arrow 269 indicating the direction of the airflow. In addition, the shape of the air outlet 255 is a fruit-like shape of a colored plant, and the appearance of the air outlet and the air outlet other than the visible cultivation medium 268 may also be designed as the shape of a colored plant flower or fruit or animal.

Generally speaking, the gas circulation can be carried out in continuous or intermittent ways: For continuous type, the fans corresponding to the exhaust port and the air supply port are continuously running at the same time; for intermittent type, a fan is first operated for a predetermined time to pollute the people. The air is sent near the plant, the fan stops, and the gas near the plant is returned to the user. The previous fan restarts, and the two fans run alternately. In order to synchronize the intermittent period of the fan with the user's breathing, a breathing sensor can be added to detect and control that when the user exhales, a fan runs to make the exhaust port suck the dirty air. When the user inhales, the fan stops. The other fan blows the purified air from the air inlet to the user's nose and nose. For operation.

When used by the user 23 during sleep, the exhaust port 251 can be made in a pillow, and the sleep sensor 24 is used to detect the breathing condition and provide an operating signal to the time relay that controls the intermittent operation of the fan. The normally open contact of the time relay controls the fan 16 of the air pipe 261. When the user 23 exhales, it runs and sends the foul air exhaled by the person to the vicinity of the plant. When the user 23 starts to inhale, the normally open contact is disconnected. Stop, the other fan 16 of the air pipe 263 connected by the normally closed contact moves on the shoulder, and returns the gas near the plant to the user. When the user 23 exhales again, the relay switches, the fan stops, and the previous fan restarts. The two fans run alternately.

In order to improve the gas exchange efficiency, the exhaust air outlet and the air supply outlet are a plurality of interconnected and elongated cavities, respectively, which are evenly staggered and distributed parallel to each other near the plant. For larger cultivation containers, parallel air can be used to provide fresh air to many people.

In FIG. 2A, the air ducts to the exhaust port 251 and the air supply port 256 of the first user are 261 and 264, respectively, and the additional air ducts to the exhaust port 2511 and the air supply port 2561 of the second user are respectively 2611 and 2641 are connected in parallel with the air ducts 261 and 264, respectively, so that a plurality of separately connected exhaust ports and air supply ports provide purified air for multiple users. A plurality of air supply openings 252 and 2052 installed in the air pipes 261 and 2611 and a plurality of air outlets 253 and 2053 installed in the air pipes 264 and 2641 are evenly staggered and distributed around the plant 211. In this embodiment, the exhaust port, the air supply port, the air exhaust port, and the air supply port may be made into a cavity with a vent hole, or may be made into a similar elongated shape to improve the gas exchange rate. In the figure, the additional light source 221 that penetrates below the foliage of the plant also provides the plant 211 with light outside of the foliage. When the light on the foliage does not illuminate the lower part of the plant, the power switch equipped with the light source 221 is turned on. In FIG. 2, the cultivation container 213, the support frame 18 and the machine base 17 are connected. The support frame 18 is connected to the cultivation container 214 and has a cavity structure.

In order to improve the quality of life, the present invention may also be provided with a plurality of containers for providing volatiles, which are in communication with the air supply port, and the connecting part is provided with a door that can be automatically opened and closed. The conditions for opening and closing the door at least include timing control, such as reaching sleep After the initial set time, an automatic door opens to connect the container with hypnotic gas volatiles to the air supply port and close it within a predetermined time. The user sleeps peacefully after inhaling the sleep gas. Similarly, the user can inhale the order before getting up Sober gas. In order to reduce the interference of the light source on sleep, the purifier can also be provided with a light-shielding cover that covers the light source and can be opened and closed.

As shown in FIG. 2C, a plurality of volatile matter containers 281 are connected to the air supply port 256 through an air pipe 264, and a communication portion is provided with a door 280 that can be automatically opened and closed. When a predetermined time arrives, a set container The door 280 is opened, the volatiles 282 are brought to the user by the airflow, and the door 280 is closed within a predetermined time.

Due to design and manufacturing reasons, undesirably small pressure differences will occur between exhaust outlets with negative pressure and between air supply outlets with positive pressure. This harmful turbulence will weaken the air outlets and exhaust outlets. Normal gas exchange between the two reduces the purification efficiency. For this purpose, the present invention adds partitions between the adjacent two groups of air supply openings and corresponding air discharge openings and on both sides of the plant area to separate the air flows normally exchanged between the two. Its direction is consistent with the air flow between the exhaust vent and the air supply vent.

In FIG. 2D, a plurality of oppositely arranged air outlets 29, air supply outlets 26 and 27, air outlets 28, and two sides of the plant 211 are additionally provided with partitions 25, the direction of which is opposite to the air outlets, The air flow is consistent between the air supply ports, which can reduce the pressure difference between the air supply ports 29 and 27 with negative pressure and the air supply ports 26 and 28 with positive pressure, and enhance the normal gas between the air supply port and the air outlet. Exchange to improve purification efficiency. Partition 25 It is preferably transparent or green, and it can also be used as a carrier for illuminating the light source below the foliage of a plant. For those vines that grow "non-standard", in order to prevent the lack of light from creeping branches and leaves to reduce the purification efficiency, a plastic fence is added slightly larger than the cultivation container. It is detachably attached to the periphery of the cultivation container. It is a A light-transmitting colored mesh that can maintain the overall shape of the plant. If necessary, a fully enclosed plastic fence can also be used. It can be a fence or a net. If the mesh is small, it also has the purpose of insect control. .

The air outlets 37 are distributed on the periphery of the plant, and a plurality of ventilation holes 38 are distributed on the surface adjacent to the plant. Under the negative pressure of the fan 16, these holes absorb the photosynthetic gas from the plant. The tube 156 is sent to the air supply port near the user. The selection button 30 is a switch for selecting the light source 22 on / partially on / all off. When it is selected, it will be delayed for a predetermined time, and the user will be exposed to a hypoxic environment for a short time, which effectively improves the tolerance of the human heart.

In FIG. 3A, the holes on the surface of the columnar air outlets 371, 372, 373 and the air supply opening 39 are divided into 351, 352, and 353. In the adjacent air outlet 371 and the hole area 351, the air outlet 372 A partition 25 is provided between the group area including the hole area 352, the air outlet 373 and the hole area 353, including nearby plants, to separate the air flow of each group of air outlets from the hole area, so as to reduce the air flow between the groups. Disturbance and increase photosynthetic efficiency. For plants cultivated in the container, the support frame is connected to the base; for multiple cultivation containers assembled in multiple layers, the support frame connected to the base can also be used to interconnect multiple cultivation containers with the base. The top of the support frame may be provided with a cover, and a handle part may be installed on the upper part of the cover, such as the handle 34 outside the cover 28 shown in FIG. 3. Correspondingly, a pulley can be installed at the lower part of the machine base.

Light sources such as fluorescent lamps, incandescent lamps, and solar lamps that contain at least the red and blue light waves required for plant photosynthesis should be used. Preferably, energy-efficient LEDs are used. Considering the height change of the plant when growing, the LEDs in the cultivation container are divided into several groups powered by two wires, and the height of the light source suspension device of each group is adjusted separately to ensure that the plant gets the best light.

The present invention can also use potted plants cultivated near the bedding as the main body of photosynthesis. The negative pressure generated by the fan causes the gas containing more CO _{2 to} flow through the light to be sucked away, and is blown to the fresh air through the blower mouth of the fan. The upper space of the place. Figure 4 shows an air purifier using the plant under the bed, in which the bed 48 and its lower three side plates and the floor-type duct 44 and the air collector installed on the side of the foot of the user 42 41 is connected to a hair dryer 46 through a pipeline 45. The negative pressure generated by the hair dryer 46 under the bed draws the gas exhaled by the user through the bed holes 43 arranged parallel to its short side on the bed 48 to the plants 11 in the cultivation container 13 through the light source. After 22 photosynthesis, the air is blown to the breathing area of the sleeping user 23 through the air outlet 47 of the fan 46. In order to improve the photosynthetic efficiency, multiple air-guiding partitions 25 divide the air flow from the bed hole 43 to the air collector 41. These partitions and side walls below the bed reduce air turbulence. In this embodiment, only one air duct is used to provide a path for the user to exhale the air. The filter 49 is easy to replace and clean.

An electric fan can also be used instead of a fan, and a potted plant illuminated by an artificial light source is placed opposite to the fan. The artificial light source is a cold light source that is not suitable for burning plants, such as LEDs. The positive pressure generated by the rotating fan blows the clean gas after photosynthesis to the user. The pot frame and the machine base are detachably assembled, the height of the electric fan and the lamp frame to the plant is adjustable, and the hanging light source can illuminate the upper and lower parts of the plant leaf surface.

FIG. 5 shows an air purifier with an electric fan. Two sides of the electric fan 50 are fixed with connecting sleeves 52. When the two sliding brackets 51 fixed on the base 54 are inserted, slide up and down to adjust the electric fan 50 and plants. The relative height of 11 is fixed by screws 532. The protruding wedge 59 of the pot holder 58 on which the cultivation container 513 is placed is matched with the groove 55 on the machine base 54 and can be detachably spliced. The lamp holder 53 is slidably fixed on the machine base 54 by a curved slide bar 56 connected thereto. On the lamp holder cover 57 above, a light source 22 and a lamp pole 514 for illuminating the plant 11 are suspended thereon. A lamp 522 suspended on the lamp pole 514 can provide light for the lower part of the leaf surface of the plant 11, and the positive pressure generated when the fan 50 rotates That is, the temperature is lowered and the clean gas after photosynthesis of the plant 11 is blown toward the user.

The testing method for testing the efficiency of the air purifier of the present invention is: artificially filling and manufacturing a test containing a fixed proportion in a laboratory with a fixed volume, a closed, and a corresponding test environment (the environmental parameters such as temperature, humidity, and pressure are well known); In the gas space, the tested plant-type air purifier is closed and started to operate. The attenuation of the concentration and time of the test gas in the laboratory is detected, and the efficiency of the air purifier can be calculated after mathematical processing.
