Detailed Description

The foregoing and other features, aspects and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the accompanying drawings, wherein like reference characters refer to the same parts throughout the description.

In the embodiment 1, the ventilation modes commonly used in the existing buildings comprise mechanical forced air exhaust, natural ventilation with windows and the like, namely an air exhaust system is arranged at the roof of the building, fresh air is continuously conveyed into the building through the operation of a fan to realize the ventilation effect, but the mode generates larger noise and depends on electric energy (larger power consumption), and when the electric power is interrupted, the mode cannot work, so that the lasting and stable ventilation and ventilation effects cannot be realized;

The ventilation mode of opening the window is to realize the ventilation and air exchange effects of the building indoor by using external natural wind, energy is not needed to be consumed, but when the strong wind weather is met, the window is required to be closed to protect the indoor (strong wind is poured into the building indoor through the opened window, the damage of internal facilities is easily caused, in addition, the strong wind weather is usually accompanied with sand dust, pollutants and the like, the closing of the window is helpful to prevent the pollutants from entering the building indoor through the window and maintain the indoor air quality), and the lasting and stable ventilation and air exchange effects cannot be realized;

in view of the above, the present application provides a new energy saving building with an air conditioning function, for solving the above problems, specifically including the following:

As shown in fig. 1, the prefabricated wall board 1 capable of realizing ventilation effect is included, the prefabricated wall board 1 is prefabricated in advance at a construction site and then is transported to a building construction site for installation (the prefabricated wall board 1 and the wall board poured in the construction site are assembled), specifically, the prefabricated wall board 1 can be arranged on each side surface of a building and a corresponding number of prefabricated wall boards 1 can be arranged according to the requirement (so as to meet the ventilation effect and ventilation effect of different side surfaces of the building);

As shown in fig. 3, a plurality of cavities 2 are vertically spaced in the prefabricated wall panel 1, the bottom of each cavity 2 is communicated with the building room, the top of each cavity 2 is communicated with a drainage channel 3 (shown in fig. 2) in the prefabricated wall panel 1, two ends of the drainage channel 3 are respectively communicated with the outdoor environment, a regulating and controlling component is arranged at the tail end of the drainage channel 3, and the regulating and controlling component realizes controlling the tail end of the drainage channel 3 to be communicated with the outdoor environment or the top of the cavity 2, and in the scheme, the following steps are set: only when the wind power of the outdoor environment reaches a certain value, the tail end of the drainage channel 3 is communicated with the outdoor environment under the control of the regulating and controlling component (when the outdoor wind speed is smaller than the value, the tail end of the drainage channel 3 is not communicated with the outdoor environment, and at the moment, the tail end of the drainage channel 3 is communicated with the top of the cavity 2), as shown in fig. 2, a gathering groove 22 (used for gathering and feeding the air flow in the outdoor environment into the drainage channel 3) is arranged at the head end position of the drainage channel 3;

the prefabricated wallboard 1 between the cavity 2 and the drainage channel 3 is provided with a plurality of communication holes 4 (used for realizing the communication between the cavity 2 and the corresponding drainage channel 3), as shown in fig. 5, the communication holes 4 are internally provided with air pressure sensing components, when the air pressure difference between the drainage channel 3 and the cavity 2 reaches a certain value (set as H), the air pressure sensing components act and enable air flow in the cavity 2 to enter the drainage channel 3 through the communication holes 4, the cavity 2 is internally provided with filtering components (used for realizing the filtration of air entering a room, namely, the filtration of harmful gas and other impurities in outdoor air, ensures that the air entering the room is in a clean state), the pressure sensing components are connected with the filtering components, and when the pressure sensing components act, the filtering components are synchronously driven to move and are accommodated, and the embodiment specifically works as follows:

As shown in fig. 2, when there is wind from the outside, the outdoor air flow first enters the flow guide 3 after being converged by the converging grooves 22 and moves in the flow guide 3 along the arrow direction in fig. 2, and the following is noted: the wind should be the light wind (i.e. the wind force lower than the set value), the regulation and control subassembly makes drainage way 3 terminal position and outdoor environment non-intercommunication (with cavity 2 top intercommunication) this moment, the air current that gets into in the drainage way 3 through gathering groove 22 can get into cavity 2, as shown in fig. 4, the air current that gets into in the cavity 2 moves to the bottom of cavity 2 along the direction that the arrow in the figure shows (the air current moves down the in-process from cavity 2 top, can pass filter assembly and filter, filter harmful air in the air current etc. impurity and clean) and send into building indoor environment from the bottom (outdoor fresh air gets into indoor and then makes indoor dirty gas outwards discharge through door, window or air exit), and then realize ventilating, the effect of taking a breath in the building room, annotate: because the wind force is small at this time and the air flow entering the drainage channel 3 enters the cavity 2 and finally enters the building room, the air pressure in the drainage channel 3 and the air pressure in the cavity 2 are maintained in the same state (namely, no air pressure difference exists at two sides), so that the air pressure sensing component at this time does not act (the communication hole 4 is in a non-conducting state);

when the external wind force is too large (exceeds a set value), the outdoor high-speed air flow enters the drainage channel 3 through the converging groove, at the moment, the tail end of the drainage channel 3 is communicated with the outdoor environment (not communicated with the top of the cavity 2 any more) under the action of the regulating and controlling component, so that the high-speed air flow entering the drainage channel 3 is directly discharged outwards from the tail end of the drainage channel 3 (as shown in fig. 6), the top of the cavity 2 is not communicated with the tail end of the drainage channel 3 at the moment, the air in the cavity 2 is basically in a static state, and the air pressure in the drainage channel 3 is reduced and lower than the atmospheric pressure due to the high-speed moving air flow in the drainage channel 3 (when the air moves rapidly in the pipeline, the kinetic energy of the rapidly flowing air increases, according to the bernoulli equation, the static pressure of the gas is correspondingly reduced because in a narrow channel, when the gas flow speed is increased, the kinetic energy of the gas is increased, the total pressure (sum of dynamic pressure and static pressure) is kept unchanged, so the static pressure is correspondingly reduced), the environment of the cavity 2 is communicated with the indoor environment (the standard atmospheric pressure), so that the air pressure difference is generated between the internal environments of the cavity 2 and the drainage channel 3 (when the external wind power reaches a set value, the air pressure difference in the cavity 2 and the drainage channel 3 reaches an H value), the air pressure sensing assembly is enabled to act, the communication hole 4 is enabled to be opened (namely, the communication between the cavity 2 and the drainage channel 3 is realized), and because the air pressure in the drainage channel 3 is lower than the indoor environment air pressure (negative pressure suction is generated), at this time, dirty air in the indoor environment is sucked into the cavity 2 through the bottom of the cavity 2 and enters into the drainage channel 3 through the communication hole 4 communicated with the cavity 2, and finally is discharged outdoors through the tail end of the drainage channel 3 along with the air flow moving at high speed in the drainage channel 3, and the air injection is as follows: in the process, the indoor polluted air (various smells such as foot odor, sweat odor, body position and the like can be generated in human metabolism, or smoke smell and wine smell can be generated when people smoke or drink indoors, paint and glue smell generated by indoor furniture, and mould smell of carpets and the like) is outwards extracted, and along with the outwards exhaust of the indoor polluted air, the external fresh air enters the room through the gaps of the door and the window, and the ventilation and air exchange effects can be realized;

Synchronous with the above process is: with the action of the air pressure sensing component, the filter component arranged in the cavity 2 is synchronously driven to be stored, namely, the filter component moves from the position shown in fig. 5 to the position shown in fig. 7 (in a stored state), and in the process that indoor dirty air enters from the bottom of the cavity 2 and moves upwards, the dirty air cannot contact with the filter component, and further, substances in the filter component cannot be consumed, so that the service life of the filter component is prolonged (because the indoor air of the part is finally required to be discharged outdoors, and therefore, the filter component is not required to be filtered and adsorbed);

When the outdoor wind power is reduced (the air power is restored to a small wind power state), the regulating and controlling component controls the tail end of the guide channel 3 to be communicated with the top of the cavity 2 again (the tail end of the guide channel 3 is not communicated with the outdoor environment any more), meanwhile, the air pressure sensing component also acts and enables the communication hole 4 to be closed again (the filter component in the accommodating state is moved into the cavity 2 again in synchronization with the air pressure sensing component, namely, the filter component in the accommodating state is moved to the position shown in fig. 5 from the position shown in fig. 7), at the moment, outdoor air flow enters the top of the cavity 2 through the guide channel 3 and is sent into a room after passing through the filter component (ventilation and ventilation are continuously carried out on the room), and therefore ventilation and ventilation can be carried out on the environment in the building room in no matter of small wind or in heavy wind weather are achieved, and lasting and stable ventilation effects are improved.

In embodiment 2, on the basis of embodiment 1, as shown in fig. 2, an air delivery duct 5 is provided in a prefabricated wall panel 1, the top of a cavity 2 is communicated with the tail end of a drainage duct 3 through the air delivery duct 5, an exhaust duct 6 communicated with the tail end of the drainage duct 3 and outdoor is provided in the prefabricated wall panel 1, a regulating and controlling component comprises a cylinder 7 slidably mounted in the tail end area of the drainage duct 3, one windward end of the cylinder 7 is set to be in an open structure (the other end of the cylinder 7 is set to be in a closed structure), a spring (the spring with a corresponding elastic coefficient is selected) is connected between the leeward end of the cylinder 7 and the drainage duct 3, an air delivery hole 8 is provided at one end of the cylinder 7 facing the air delivery duct 5, and an exhaust hole 9 is provided at one end of the cylinder 7 facing the exhaust duct, and the embodiment specifically works as follows:

When the outdoor natural wind is smaller, the cylinder 7 arranged in the guide channel 3 is positioned as shown in fig. 2, at the moment, the position of the wind feeding hole 8 on the cylinder 7 just corresponds to the position of the wind feeding channel 5 (so that the cavity 2 and the guide channel 3 corresponding to the cavity are in a communicating state, the positions of the air exhausting hole 9 and the air exhausting channel 6 arranged on the cylinder 7 are not corresponding, when the external air flow enters the guide channel 3, the external natural wind can only enter the cavity 2 through the wind feeding hole 8 and the wind feeding channel 5), the external natural wind enters the guide channel 3 through the gathering groove 22, then enters the cylinder 7 and enters the cavity 2 through the matched wind feeding hole 8 and the wind feeding channel 5, and after the air flow entering the cavity 2 moves from top to bottom and passes through the filtering assembly (air filtering is completed), the air flow enters the building room from the bottom of the cavity 2 (so as to realize the effects of ventilating and ventilating the building room);

As the outdoor wind force increases, the flow rate of the air flow entering the drainage channel 3 through the gathering groove 22 gradually increases (the kinetic energy of the air flow increases), so that the impact load force from the wind received by one end of the cylinder 7 gradually increases, the cylinder 7 is forced to move towards the direction of the compression spring against the elastic force of the spring connected with the cylinder 7, the overlapping area between the air supply hole 8 and the air supply channel 5 gradually decreases as the cylinder 7 moves, the air flow entering the cavity 2 from the drainage channel 3 in unit time decreases, the air pressure in the drainage channel 3 further increases, and the cylinder 7 is forced to move towards the direction of the compression spring for a larger distance, and during the process: the overlapped area between the air supply hole 8 and the air supply duct 5 is gradually reduced, and the overlapped area between the air exhaust hole 9 and the air exhaust duct 6 is gradually increased, so that part of the air flow entering the drainage duct 3 through the gathering groove 22 enters the cavity 2 through the air supply duct 5, and the other part of the air flow is discharged outwards through the matched air exhaust hole 9 and the air exhaust duct 6, thereby realizing the diversion of the air flow with higher air speed entering the drainage duct 3 from the outside, so that a large amount of high-speed air flow enters the cavity 2 through the air supply duct 5 and damages indoor facilities after entering the indoor through the cavity 2;

If the external natural wind force continues to increase, the impact load force of the natural wind acting on the closed end of the cylinder 7 is further increased until the cylinder 7 moves from the position shown in fig. 2 to the position shown in fig. 6, at this time, the air delivery hole 8 is completely staggered with the air delivery channel 5, so that the air delivery channel 5 is in a non-conducting state, and the air outlet hole 9 arranged on the cylinder 7 just corresponds to the air outlet channel 6 completely (a stop matched with the closed end of the cylinder 7 can be arranged in the air guide channel 3, so that when the cylinder 7 moves to the position shown in fig. 6, the stop cannot move continuously due to the blocking of the stop, and the stop is not shown in the figure), at this time, the wind entering into the air guide channel 3 from the gathering groove 22 does not enter into the cavity 2 but is directly discharged to the external environment through the air outlet channel 6 all the time, as shown in fig. 4, a guide cover 29 communicated with the air outlet channel 6 is arranged outside the prefabricated wall plate 1 (the opening of the guide cover 29 is downward, so that the air flow discharged through the air outlet channel 6 is discharged to the external environment from top to bottom through the guide cover 29);

Note that: in this solution, the spring coefficient of the spring connected to the cylinder 7 should be selected according to the requirement, that is, by setting how large the external natural wind reaches, the closed end of the cylinder 7 is subjected to the wind impact load force to overcome the spring elastic force, and then the initial position shown in fig. 2 is moved to the position shown in fig. 6 (so as to realize that no air is supplied into the building room when the external wind is greater than a certain value), and in this solution, the spring coefficient of the spring connected to the cylinder 7 should be selected according to the set wind value;

When the cylinder 7 is at the position shown in fig. 6 (when the external wind power reaches the set value), the air pressure difference between the air pressure in the cavity 2 and the air pressure in the drainage channel 3 reaches the set value H, the air pressure sensing component acts and the communication hole 4 is in a conducting state, so that a strong negative pressure suction force is generated on the air in the cavity 2 (namely, the building chamber), dirty air in the building chamber continuously enters the cavity 2 from the bottom of the cavity 2 and enters the drainage channel 3 through the communication hole 4 in the conducting state, and the dirty air and the air flow moving at high speed in the drainage channel 3 are discharged to the outdoor environment together with the air flow moving at high speed in the drainage channel 6 through the exhaust channel 6 (as shown in fig. 7), and when the air pressure sensing component acts, the air pressure sensing component synchronously drives the filter component to be stored, so that the dirty air in the room does not pass through the filter component any more in the process of moving up in the cavity 2, and unnecessary consumption of filter substances in the filter component is reduced (the service life of the filter component is prolonged);

when the wind power of the external environment is gradually reduced, the impact load force from the wind power received by one end of the cylinder 7 is gradually reduced, and the cylinder 7 is driven to move to the initial position under the action of the spring until the cylinder 7 moves to the position shown in fig. 2 (ventilation and ventilation are continued in the building), in the process, the difference of the air pressure in the drainage channel 3 and the cavity 2 is recovered (until no air pressure difference exists) along with the reduction of the wind power of the external environment, so that the air pressure sensing assembly acts again and the communication hole 4 is in a non-conducting state, and the air pressure sensing assembly is synchronous with the air pressure sensing assembly: so that the filter assembly in the stored state is moved into the cavity 2 again for realizing the filtration of the air entering the building from the outside through the drainage channel 3 and the cavity 2.

In embodiment 3, based on embodiment 1, as shown in fig. 2, the communication hole 4 is provided in a stepped shape, and the inner diameter of the end close to the guide channel 3 is larger, the pressure sensing component comprises a sensing ball 10 arranged in the larger inner diameter end of the communication hole 4, the sensing ball 10 is connected with the filtering component through an L-shaped rod 11, the L-shaped rod 11 passes through the communication hole 4 and is arranged in the cavity 2 to be fixedly connected with the filtering component (as shown in fig. 5), a storage cavity 14 matched with the filtering component is arranged in the prefabricated wallboard 1 at a position corresponding to the filtering component (one end of the filtering component, facing the storage cavity 14, is slidably arranged in the storage cavity 14 and is connected with a spring between the storage cavity 14), as shown in fig. 3, an annular groove 12 is coaxially arranged in the prefabricated wallboard 1 at the smaller inner diameter end of the communication hole 4, and a sensing cylinder 13 is axially slidably arranged in the annular groove 12 (a spring is connected between the sensing cylinder 13 and the annular groove 12), when the outside natural wind is smaller, the sensing ball 10 is tightly abutted against the end position of the sensing cylinder 13 under the action of the filtering component and the spring connected with the filtering component at the moment, the sensing cylinder 13 is contracted in the annular groove 13 (the spring arranged to be connected with the sensing cylinder 13 at the moment) is in a compressed state, as shown in fig. 3, and the communication hole 4 is not in a compressed state;

When the external wind force increases gradually, the cylinder 7 will move gradually towards the direction of compressing the spring connected with the cylinder under the impact of the wind force, so that the air flow in the drainage channel 3 entering the cavity 2 through the air delivery channel 5 decreases gradually, and the air flow discharged outwards through the air exhaust channel 6 increases gradually, in the above process, since the air flow in the cavity 2 decreases gradually, it is worth noting that: the air flow entering the cavity 2 through the air delivery duct 5 has a obviously slowed down process, because the cross section of the cavity 2 is larger, when the air flow moving fast enters the cavity 2 through the air delivery duct 5, the air flow velocity in the drainage duct 3 is larger, so that the air pressure in the cavity 2 and the drainage duct 3 generates a obvious difference (the air pressure in the cavity 2 is larger than the air pressure in the drainage duct 3), and the sensing ball 10 is forced to move towards a direction far away from the cavity 2 under the action of the air pressure difference (along with the movement of the sensing ball 10, the L-shaped rod 11 synchronously drives the filter assembly to slide from the cavity 2 into the accommodating cavity 14 and is compressed on a spring connected with the filter assembly), so that the air flow is synchronous with the air flow: along with the movement of the sensing ball 10, the sensing cylinder 13 synchronously moves under the action of a spring connected with the sensing ball, the movement distance of the cylinder 7 is further increased along with the continued increase of external wind power, the air flow entering into the cavity 2 is further reduced (the air pressure difference between the cavity 2 and the drainage channel 3 is further increased), the movement distance of the sensing ball 10 is further increased under the action of the air pressure difference until when the external wind power reaches a set value (when the air flow in the drainage channel 3 does not enter into the cavity 2 through the air delivery channel 5 any more and is directly discharged from the exhaust channel 6), the air pressure difference between the cavity 2 and the drainage channel 3 reaches a set value H, when the air pressure difference reaches the H value, the sensing ball 10 and the sensing cylinder 13 are not abutted any more (when one end of the sensing cylinder 13 facing the sensing ball 10 is not closed and is in a conducting state), and the communication hole 4 is in a conducting state (as shown in fig. 6);

Notably, are: when the air pressure difference reaches the value H (i.e. approaches the value H), the sensing cylinder 13 is not continuously moved under the action of the spring connected with the sensing cylinder (the compressed potential energy of the spring is completely released at the moment), and as the air pressure difference is continuously increased (the value H is reached), the sensing ball 10 continuously moves a little distance away from the cavity 2 under the action of the pressure difference, so that separation between the sensing ball 10 and the sensing cylinder 13 is realized, meanwhile, the filter assembly is synchronously accommodated in the accommodating cavity 14 under the driving of the sensing ball 10 (as shown in fig. 7, a stop block can be arranged in the accommodating cavity 14 and the filter assembly is limited to continuously move, namely, when the air pressure difference reaches the value H, if the external wind force is continuously increased (exceeds a set value), the filter assembly and the sensing ball 10 are not continuously moved, so that the distance between the ends of the sensing ball 10 and the sensing cylinder 13 is maintained at the current level), and the sensing ball 10 extends out of the communication hole 4 and is placed in the guide channel 3, and the spring connected with the filter assembly stores potential energy with a certain size;

As shown in fig. 6, at this time, the communication hole 4 is in a conducting state and the air pressure difference in the cavity 2 and the drainage channel 3 is larger, so that a negative pressure suction force is generated on the air in the cavity 2, and the air in the cavity 2 is continuously sucked into the drainage channel 3 through the communication hole 4 (along with the air flow moving at high speed in the drainage channel 3 being discharged to the outside through the exhaust channel 6), as shown in fig. 7, the indoor relatively dirty air is continuously discharged outwards under the action of the negative pressure, and the dirty air is not contacted with the filter assembly (the filter assembly is accommodated in the accommodating cavity 14) in the process of moving upwards along the cavity 2, as shown in fig. 6, if the external wind force exceeds a set value and is continuously increased, a stronger negative pressure suction force is generated, so that the discharging efficiency of the indoor dirty air is improved, and if the external wind force value is in a continuously fluctuating state (on the premise of being larger than the set value), the generated negative pressure suction force is also fluctuated along with the condition;

Notably, are: as shown in fig. 6, since the sensing ball 10 is located in the guiding channel 3 and occupies a certain space in the guiding channel 3 (the flow section of the guiding channel 3 corresponding to the sensing ball 10 for allowing the gas to circulate is reduced), when the external high-speed gas flows through the section of the guiding channel 3 where the sensing ball 10 is located, there is a speed increasing process (this is based on the basic principle of fluid dynamics, if the flow section of the pipeline is reduced and the flow rate of the fluid is unchanged, the flow rate of the fluid will necessarily increase), as the air flowing through the section corresponding to the sensing ball 10 increases, the air pressure in the section and the air pressure difference in the cavity 2 further increase, thereby generating a larger negative pressure suction force, and being beneficial to improving the discharging efficiency of indoor dirty air;

when the external wind force gradually decreases, the air pressure difference in the drainage channel 3 and the cavity 2 is synchronously reduced, at the moment, along with the continuous decrease of the air pressure difference, the filter assembly slides outwards from the storage cavity 14 under the action of the connecting spring and synchronously drives the sensing ball 10 to move towards the cavity 2 until the sensing ball 10 is in contact with the end part of the sensing cylinder 13 again (at the moment, the communication hole 4 is not conducted any more), the air delivery hole 8 arranged on the cylinder 7 is partially overlapped with the air delivery channel 5, at the moment, part of the air flow in the drainage channel 3 starts to enter the cavity 2 through the air delivery channel 5 (enters the room), until the external wind force value is restored to a smaller level, the filter assembly is reset under the action of the connecting spring (the filter assembly is in the position shown in fig. 4, at the moment, the sensing ball 10 and the sensing cylinder 13 are in the position shown in fig. 3), and the cylinder 7 is also moved from the position shown in fig. 2 (at the moment, the air flow in the drainage channel 3 is completely fed into the room through the air delivery channel 5), and indoor ventilation is continuously realized.

In embodiment 4, on the basis of embodiment 3, as shown in fig. 5, the filter assembly comprises a filter box 15 with one end slidably mounted in a storage cavity 14, and active carbon is stored in the filter box 15, as shown in fig. 2, a plurality of meshes 16 are uniformly distributed on the upper wall and the lower wall of the filter box 15, the bottom end of an l-shaped rod 11 and the upper wall of the filter box 15 are fixedly mounted, as shown in fig. 4, when air flow enters the cavity 2 from the air delivery duct 5 and moves downwards, the air flow sequentially passes through the meshes 16 and is filtered by the active carbon in the filter box 15, and finally is delivered into a room through the bottom of the cavity 2.

In embodiment 5, in order to further improve the efficiency of discharging indoor polluted air when the outside wind force is too large, the embodiment further improves, as shown in fig. 3, when the sensing ball 10 is arranged, the diameter of the sensing ball is equal to the size of the larger end of the communication hole 4, the sensing ball 10 is divided into two parts, namely, a fixed part 17 fixedly mounted with the L-shaped rod 11 and a movable part 18 slidably mounted with the fixed part 17, as shown in fig. 8, a slide bar and a slide tube (not numbered in the drawing) are arranged in the fixed part 17 and the movable part 18 for realizing the sliding mounting of the movable part 18 and the fixed part 17, and a spring is connected between the movable part 18 and the fixed part 17, and a flexible piece 19 (which can be made of natural latex and plastic) is arranged at the matching part of the fixed part 17 and the movable part 18, as shown in fig. 2, when the sensing ball 10 is positioned in the communication hole 4, the outer arc surface of the movable part 18 is abutted against the inner wall of the communication hole 18 (so that the spring connected between the movable part 18 and the fixed part 17 is in a compressed state), as shown in fig. 8, and the flexible piece 19 is also positioned in the flexible part 19 is folded to be positioned in the flat state of the communication hole 4, and the flexible piece (19 is folded like a groove is arranged on the flexible part 30, and the flexible piece is folded part is folded to be arranged in the flexible part 30, and is folded part is folded to be shaped like the flexible part 3, and is arranged on the communication hole 3, and is folded part is like the communication hole 3, and is folded part is folded 3, and is like the communication hole 3 is arranged on the communication hole 3 and is folded part is arranged on the flexible part 3);

when the external wind force increases and the sensing ball 10 moves from the inside of the communication hole 4 to the inside of the guide channel 3 under the action of the air pressure difference, when the point c of the movable part 18 does not move to the round angle position of the extension bar 30, the movable part 18 is limited to be always in a closed state with the fixed part 17, after the point c of the movable part 18 passes over the round angle position of the extension bar 30, the movable part 18 is not limited by the extension bar 30 any more and starts to move relative to the fixed part 17 under the action of the springs inside the movable part 18 and the fixed part 17 until the sensing ball moves to the position shown in fig. 6, at the moment, the movable part 18 is fully unfolded relative to the fixed part 17 (a limiting block can be arranged in a sliding cylinder arranged in the fixed part 17 and used for limiting the maximum sliding distance of the movable part 18 relative to the fixed part 17), at the moment, the flexible part 19 is also in a fully unfolded state, the matched fixed part 17, flexible part 19 and movable part 18 are equivalent to a column structure, when the air flow in the drainage channel 3 and flowing through the column structure sections generates speed increasing, the air flow keeps the speed after increasing in the column structure corresponding sections, once the air flow passes through the column structure corresponding sections, the air flow speed is reduced (because the effective conduction cross section length provided by the column structure in the air flowing direction is further prolonged relative to the prior sensing ball 10), the longer and effective conduction cross section reduced sections are provided, the air flow maintains stronger negative pressure suction force (generates stronger adsorption effect) in the column structure corresponding sections after passing through the sections and completing speed increasing, and the efficiency of the discharging system of indoor dirty air is further improved, compared with the prior art sensing ball 10, when the air flow passes over the sensing ball 10, the effective conduction cross section of the air is increased (the cross section of the guide channel 3 is restored), the flow speed is reduced (due to the arc-shaped structure of the sensing ball, the negative pressure suction section with larger length and strength generated by the existence of the cylinder structure is difficult to provide, so that the negative pressure adsorption effect is not obviously improved, and the discharge efficiency of indoor polluted air is reduced);

Notably, are: the maximum distance that the movable part 18 can move relative to the fixed part 17 is required to satisfy: when the a point of the movable portion 18 is not allowed to pass over the extension bar 30 and the filter box 15 drives the sensing ball 10 to move towards the initial position through the L-shaped rod 11, the movable portion 18 moves towards the direction approaching the fixed portion 17 under the constraint of the extension bar 30, before the fixed portion 17 and the movable portion 18 are not contacted with the end of the sensing cylinder 13, the a point of the movable portion 18 needs to move to a projection range of the sensing cylinder 13 along the central axis direction (as shown in a right partial enlarged view in fig. 6), so that the filter box 15 drives the sensing ball 10 (the fixed portion 17 and the movable portion 18) to move towards the initial position smoothly through the L-shaped rod 11, if the a point of the movable portion 18 does not move to a projection range of the sensing cylinder 13 along the central axis direction, the fixed portion 17 is already contacted with the sensing cylinder 13, the movable portion 18 is blocked by the outer wall of the sensing cylinder 13 and can not be folded with the fixed portion 17, and the following is noted: in this embodiment, since the movable portion 18 moves relative to the fixed portion 17, and thus the volume of the space surrounded by the fixed portion 17, the movable portion 18, and the flexible member 19 increases, holes (not shown in the drawing) need to be provided in the fixed portion 17 and the movable portion 18 to enable the outside air flow to enter the space during the movement of the movable portion 18 relative to the fixed portion 17, so as to fill the space increased by the movement of the movable portion 18, and the springs connected between the movable portion 18 and the fixed portion 17 are compressed again during the folding process.
