[0002] At present, the multi-level ecological pond joint control wetland technology is an ecological treatment technology that integrates the concepts and technical cores of near-natural ecological wetlands, spatiotemporal purification of low-pollution water, and natural connectivity of water systems and rivers. It uses small water bodies that have been properly artificially modified and mainly relies on the natural biological purification function to purify low-pollution water. The purification process of low-pollution water in ecological ponds is extremely similar to the self-purification process of natural water bodies, mainly including spatiotemporal dilution purification, long-term storage of low-pollution water in the pond, and the comprehensive degradation of various microorganisms including aquatic plants through the metabolic activities of organisms in the pond. This technology has a series of more significant advantages, such as full utilization of terrain, simple structure, and low construction cost; it can realize sewage resource utilization and water circulation, which not only saves water resources but also obtains economic benefits; low treatment energy consumption, convenient operation and maintenance, and low cost; beautification of the environment, and formation of ecological landscape.

[0003] In related technology, Chinese patent publication number CN110342645A proposes a multi-stage pond-linked wetland water quality enhancement and purification system, comprising a pretreatment pond, a facultative pond, a high-efficiency wetland purification system, an ecological pond, an aquatic plant pond, a dike, and bionic aquatic plants. The pretreatment pond is connected to the facultative pond via a dike, which in turn is connected to the high-efficiency wetland purification system via a dike. The high-efficiency wetland purification system is connected to the ecological pond via a dike, which is connected to the aquatic plant pond via a dike. The bionic aquatic plants are internally connected to the pretreatment pond, the facultative pond, and the high-efficiency wetland purification system. The high-efficiency wetland purification system comprises a first aerated aerobic pond, a second aerated aerobic pond, a first centrifugal submerged aerator, a second centrifugal submerged aerator, a first submerged flowmaker, and a second submerged flowmaker. Compared to traditional technologies, this system enhances nitrogen and phosphorus removal in each pond, reduces the pollution load of rivers entering the lake, improves water quality, and establishes a comprehensive wetland aquatic ecosystem.

[0004] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: a grille is set at the water inlet of the pretreatment pond to intercept floating garbage and suspended matter in the upstream water. Currently, the intercepted floating garbage can only be cleaned manually, which has the defects of low work efficiency and high labor costs. Summary of the Invention

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The bracket is installed at the connection point of the pretreatment pond, and can also be installed above the grille. The lifting mechanism is used to pick up floating objects intercepted by the grille. The water filtering mechanism is used to drain the picked-up floating objects to prevent them from being soaked for a long time and generating odor. The regulating mechanism is mainly used to disperse and deodorize the collected floating objects.

[0022] 2. In the initial state of the abutment piece, it abuts against the blades of the impeller, and the torsion spring is in a deformed state, so that the abutment piece abuts against the blades of the impeller, and at this time the trigger hole is in an open state, and the light sensor can identify the light source. Only when the impeller rotates faster can the impeller blades transport the abutment piece into the trigger hole. As long as the impeller rotates fast enough, it proves that the external wind force is strong. When the impeller blades abut against the abutment piece and squeeze the abutment piece toward the trigger hole, the next blade rotates to the position of abutting against the abutment piece before the abutment piece swings downward, and the abutment piece is always in the trigger hole and blocks the trigger hole. When the light sensor does not identify the light source, it proves that the external wind force is strong enough, and the ventilation frame can be opened. The ventilation frame is pulled to the outside of the regulating box, and the odor in the regulating box can be dispersed at this time. If the wind force is not strong enough, the ventilation hole will not be opened to prevent other impurities from entering the regulating box.

[0023] 3. First, control the flow of the setting tube. The flow of the setting tube can be controlled by rotating the threaded rod. At this time, it is necessary to open the water outlet of the upper box and the water inlet of the lower box, and close the water inlet of the upper box and the water outlet of the lower box. The water in the upper box begins to enter the lower box through the setting tube. After the water in the upper box completely enters the lower box, the water level sensor can recognize that the set time has been reached. In this process, as the ventilation frame rises, the monitoring rod is lifted and moves upward, and the monitoring hole on the monitoring rod moves upward. At this time, the infrared receiver cannot receive the signal from the infrared transmitter. At this time, the infrared receiver controls the movement of the setting electric push rod, and the setting electric push rod controls the setting rod to move toward the proximity switch. If the time is reached, the movement of the setting electric push rod stops. Regardless of whether the subsequent ventilation frame moves upward, the setting electric push rod will not be triggered to move. At this time, the setting rod has not reached the position of the proximity switch, which proves that the number of ventilations is not enough, and the deodorant needs to be released to deodorize the floating objects in the adjustment box.

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] The present application discloses a multi-level pond joint control wetland water quality enhancement purification system. Figure 1-Figure 5 A multi-stage pond-linked wetland water quality enhanced purification system includes a pretreatment pond 1, a facultative pond, a high-efficiency wetland purification system, an ecological pond and an aquatic plant pond connected in sequence. The pretreatment pond 1 removes sediment and suspended organic particulate matter by arranging bionic water plants to enhance purification measures. At the same time, a grille 2 is set at the wetland inlet to intercept floating garbage and suspended matter in the upstream water; the facultative pond removes soluble organic pollutants by arranging bionic water plants, aeration equipment and aquatic plants, and is connected in series with the post-aeration aerobic pond to promote the removal of nitrogen and phosphorus nutrients; the high-efficiency wetland purification system uses series aeration to increase the activity of biofilm-forming microorganisms in the pond body, improve the removal capacity of ammonia and nitrogen, and adjust the aeration volume in time according to the carbon source content in the water body, provide denitrification conditions, and improve the removal of total nitrogen in the water body; the ecological pond degrades and transforms pollutants in the pond by arranging ecological floating islands, aquatic plants, aquatic animals and other food chains to transfer and transform materials and energy step by step.

[0032] The pretreatment pond 1 is provided with a grid 2 at the water inlet position. The pretreatment pond 1 is provided with a cleaning mechanism for automatically processing floating objects and a photovoltaic structure for providing electric energy to the cleaning mechanism on the water inlet surface of the grid 2. In this embodiment, all equipment involving the use of electric energy are provided with a photovoltaic structure, and this embodiment will not be repeated. The cleaning mechanism includes a bracket 3 arranged on the pretreatment pond 1, a lifting mechanism for scooping up floating objects, a water filtering mechanism for filtering the floating objects, and an adjusting mechanism for environmentally friendly treatment of the floating objects; the bracket 3 is arranged at the connection point of the pretreatment pond 1, and of course it can also be arranged above the grid 2. The lifting mechanism is used to scoop up the floating objects intercepted by the grid 2, and the water filtering mechanism is used to drain the scooped floating objects to prevent the floating objects from generating odor after being soaked for a long time. The adjusting mechanism is mainly used to disperse and deodorize the collected floating objects.

[0033] The lifting mechanism includes a frame 4 that is lifted and lowered on the bracket 3, a bottom frame 5 that is elastically set on the frame 4, and a transmission assembly that realizes the elastic setting of the bottom frame 5. The bottom frame 5 is tilted toward the water filtering mechanism and its lowest side wall is in close contact with the grille 2. The lifting and lowering of the frame 4 can be achieved by an electric push rod, and the side of the frame 4 facing the grille 2 is open. In the initial state, the frame 4 is below the liquid surface. When the frame 4 is pulled up, the frame 4 will collect the floating objects in front of the grille 2. Since the bottom frame 5 is tilted, the floating objects flow toward the water filtering mechanism under the action of their own weight, thereby achieving the effect of automatically collecting the floating objects.

[0034] The transmission assembly includes two slides 6, two springs 9 and a first electromagnet 8 which is lifted and lowered on the bracket 3. Slide grooves 7 are provided on the two opposite side walls of the frame 4. The slide 6 is slidably arranged in the slide groove 7. The two ends of the spring 9 are fixedly connected to the upper side wall of the slide 6 and the inner wall of the corresponding end of the slide groove 7. The first electromagnet 8 is adsorbed on the bottom frame 5. The lifting and lowering of the first electromagnet 8 is also achieved by an electric push rod. The slide groove 7 extends along the vertical direction of the frame 4 and the two ends of the slide groove 7 are open. In the initial state, the spring 9 is in a compressed state, so the slide 6 corresponding to the bottom frame 5 is also located at the bottom end of the slide groove 7; when the frame 4 is pulled When it reaches above the liquid level, the floating objects also achieve the effect of partial drainage. When the floating objects reach the water filtering mechanism, in order to reduce the floating objects from being clamped on the bottom frame 5, it is necessary to control the first electromagnet 8 to descend to adsorb the bottom frame 5, and control the frame 4 to move downward until the initial position of the bottom frame 5 on the frame 4 is below the liquid level. Then, the first electromagnet 8 is powered off. Under the elastic force of the spring 9, the bottom frame 5 impacts downward and violently impacts the liquid surface. The floating objects above the bottom frame 5 are impacted off from the bottom frame 5. After the bottom frame 5 and the frame 4 are pulled up from below the liquid level, the washed-off floating objects fall into the water filtering mechanism.

[0035] The water filtering mechanism includes a water filter box 10 arranged on the bracket 3, a water filter plate 11 movably arranged at the bottom of the water filter box 10, a control component for controlling the movement of the water filter plate 11, and a detection component for detecting the draining of the water filter box 10. The water filter box 10 is located above the grille 2 and the upper end is an opening. The water filter plate 11 swings toward the adjustment mechanism. The top of the water filter box 10 is an opening and the lowest position of the bottom frame 5 just moves to be flush with the plane of the opening of the water filter box 10. Then, when the frame 4 moves to the specified position, the floating objects fall into the water filter box 10, and the floating objects that fall into the water filter box 10 start to filter water under the action of the water filter plate 11. The volume of the water filter box 10 is far The volume of the filter box 10 is larger than that of the frame 4, so the side of the filter box 10 away from the frame 4 is opened, but floating objects will not fall. The filter plate 11 is rotatably connected to the filter box 10 and the side of the filter plate 11 close to the filter box 10 is rotatably connected to the filter box 10. The control component includes a control motor 12, which is fixed to the side wall of the filter box 10 and is used to control the rotation of the filter plate 11. The filter plate 11 is horizontal in the initial state. After the filter plate 11 completes the drainage work, the control motor 12 controls the filter plate 11 to rotate toward the side of the filter box 10, that is, toward the direction of the adjustment mechanism. At this time, the filtered floating objects enter the adjustment mechanism for deodorization.

[0036] The detection component includes a squeezing plate 13 that is lifted and lowered in the water filter box 10, an adsorption member 14 that is movably arranged under the water filter plate 11, and a viewing portion for checking whether water is adsorbed on the adsorption member 14. The squeezing plate 13 squeezes out water from floating objects in the water filter box 10, and the adsorption member 14 moves along the length direction of the water filter box 10. The water filter box 10 is fixedly connected with an adsorption electric push rod 15 for controlling the movement of the adsorption member 14. The lifting and lowering of the squeezing plate 13 is also achieved by the electric push rod. The adsorption member 14 can be made of sponge. The squeezing plate 13 is initially located above the top of the opening of the water filter box 10. In this embodiment, it is determined that since floating objects can float above the liquid level, the floating objects can be squeezed and drained. Therefore, the adsorption member 14 is away from the position of the water filter plate 11 in the initial position to avoid affecting the subsequent detection work of the adsorption member 14.

[0037] The inspection portion includes an inspection chamber 16, a water sensor 17 movably arranged in the inspection chamber 16, and a water outlet plate 18 fixed in the inspection chamber 16. The water outlet plate 18 is provided with a plurality of protrusions 19 on the side facing the adsorption member 14. The bottom wall of the inspection chamber 16 is inclined and inclined toward the adsorption electric push rod 15. The water sensor 17 is arranged on the side where the bottom wall of the inspection chamber 16 is higher. The inspection chamber 16 and the adsorption electric push rod 15 are respectively arranged on two opposite side walls of the water filter box 10. The opening size of the inspection chamber 16 is larger than that of the adsorption member 14. The adsorption member 14 is in close contact with the lower wall of the water filter plate 11 during movement. Since the adsorption member 14 adopts a sponge, after the squeezing plate 13 squeezes the floating objects for a period of time, the adsorption member 14 is controlled to start moving and fit with the lower wall of the water filter plate 11. If there is still residual water in the floating objects, the adsorption member 14 will absorb the water during movement. For adsorption, of course, the adsorption member 14 can also be controlled to move multiple times, and then the adsorption member 14 can be transported to the inspection chamber 16, and the adsorption member 14 can be continued to be squeezed. If the adsorption member 14 adsorbs water, but when the adsorption member 14 is squeezed, no obvious water is squeezed out, then the water sensor 17 does not recognize the water. Of course, it is also possible that the adsorption member 14 does not adsorb water, and at this time the water sensor 17 also does not recognize the water; and when there is water on the water filter plate 11, the adsorption member 14 begins to adsorb water, and the water is squeezed out and falls into the inspection chamber 16 during the squeezing process of the adsorption member 14. The water begins to flow along the inspection chamber 16 and flows to the position of the water sensor 17. The water sensor 17 is controlled by a PLC controller and is connected to a buzzer. If the buzzer sounds an alarm, it proves that the floating objects still need to be drained, and the adsorption member 14 can be quickly drained after the water is squeezed out.

[0038] The regulating mechanism includes a regulating box 20, a ventilation component for ventilating the regulating box 20, a blocking component for sealing the top of the regulating box 20, a monitoring component for monitoring the number of ventilations, and a freshening component for deodorizing the regulating box 20. The top of the regulating box 20 is open, and the side walls of the regulating box 20 are provided with multiple ventilation holes 21. The ventilation component is used to block the ventilation holes 21 on the side walls of the regulating box 20. The regulating box 20 is also fixed on the bracket 3. The upper end of the regulating box 20 is open, the ventilation component is used to blow air to deodorize floating objects in the regulating box 20, the blocking component is used to seal the top of the regulating box 20, and the monitoring component is used to monitor the number of ventilations. For example, three ventilations are required within the set time to prevent odor from being generated. If the number of ventilations is less than three times, odor is likely to be generated. If the number of ventilations is not enough, the freshening component is required to start deodorizing the floating objects stored in the regulating box 20.

[0039] The refreshing component includes a storage tank and a nozzle connected to the storage tank. The storage tank is set in the external environment, and the nozzle and the storage tank are connected by a hose. The blocking component includes a blocking plate and a blocking motor. The blocking motor is fixed to the outer wall of the regulating box 20. The blocking plate and the regulating box 20 are rotatably connected, and the rotation axis between the blocking plate and the regulating box 20 is located on the symmetrical plane of the blocking plate. When the floating objects are filtered out, the control motor 12 controls the water filter plate 11 to rotate, and at the same time, it is necessary to control the rotation of the blocking plate. When the blocking plate is in a horizontal state, the regulating box 20 is closed, and when it is in a vertical state, the regulating box 20 is in an open state. After the floating objects fall from the blocking plate into the regulating box 20, the blocking plate is closed.

[0040] The ventilation assembly includes a ventilation electric push rod 22, a ventilation frame 23 and a triggering part for triggering the ventilation electric push rod 22 to work. The ventilation electric push rod 22 is fixed in the adjustment box 20 and is used to control the movement of the ventilation frame 23 in the vertical direction. The four sides of the adjustment box 20 are provided with ventilation cavities for the sliding adaptation of the ventilation frame 23. The ventilation frame 23 is set to be rectangular in this embodiment, and the top and bottom of the ventilation frame 23 are opened. The ventilation electric push rod 22 is fixed on the adjustment box 20, and the ventilation cavity and the ventilation hole 21 are connected. In the initial state, the ventilation frame 23 is located in the ventilation cavity. At this time, the ventilation frame 23 closes the ventilation hole 21, and the sealing plate fully adapts to the opening of the adjustment box 20 and the sealing plate will not affect the movement of the ventilation frame 23 during rotation.

[0041] The triggering part includes a trigger box 24, an impeller 25, an abutment piece 26, a light source 27, a bottom box 28 and a light sensor 29. The impeller 25 is rotatably arranged in the bottom box 28. The trigger box 24 is provided with a trigger hole 30. There are two impellers 25, one impeller 25 is located in the bottom box 28, and the other impeller 25 is located in the bottom box 28. The blades of the impeller 25 located in the bottom box 28 abut against the abutment piece 26. The trigger hole 30 is connected to the bottom box 28. The abutment piece 26 is elastically hinged at the position of the trigger hole 30, and the abutment piece 26 is in contact with the trigger hole 30. The trigger hole 30 is adapted, the light source 27 is arranged in the trigger box 24, the blades of the impeller 25 abut against the outer wall of the abutment piece 26, and when the speed of the impeller 25 reaches the set value, the abutment piece 26 blocks the trigger hole 30. The light sensor 29 is arranged in the bottom box 28, and the light sensor 29 is electrically connected to the ventilation electric push rod 22. The abutment piece 26 is hingedly arranged at the position of the trigger hole 30 and the axial direction of the hinge shaft is perpendicular to the length direction of the trigger hole 30. The abutment piece 26 is fixedly connected to the inner wall of the trigger hole 30 by a torsion spring, and when the abutment piece 26 is fixedly connected to the inner wall of the trigger hole 30, the abutment piece 26 is fixedly connected to the inner wall of the trigger hole 30 by a torsion spring. In the initial state, the contact piece 26 abuts against the blades of the impeller 25, and the torsion spring is in a deformed state, so that the contact piece 26 abuts against the blades of the impeller 25. At this time, the trigger hole 30 is in an open state, and the light sensor 29 can identify the light source 27. Only when the speed of the impeller 25 is faster, the blades of the impeller 25 can transport the contact piece 26 into the trigger hole 30. As long as the speed of the impeller 25 is fast enough, it proves that the external wind force is strong. When the blades of the impeller 25 abut against the contact piece 26, the contact piece 26 is squeezed toward the trigger hole 30. When pressure is applied, the next blade rotates to the position in contact with the abutment piece 26 before the abutment piece 26 swings downward, and the abutment piece 26 is always in the trigger hole 30 and blocks the trigger hole 30. When the light sensor 29 does not recognize the light source 27, it proves that the external wind force is strong enough to open the ventilation frame 23, and the ventilation frame 23 is pulled to the outside of the regulating box 20. At this time, the regulating box 20 can be deodorized. If the wind force is not strong enough, the ventilation hole 21 will not be opened to prevent other impurities from entering the regulating box 20.

[0042] The monitoring component includes a setting component for setting time, an adjustment plate 31 arranged on the adjustment box 20, a monitoring rod 32 that slides and adapts to the adjustment plate 31, an infrared transmitter 33 and an infrared receiver 34. The monitoring rod 32 is provided with a monitoring hole 35. The signal emitted by the infrared transmitter 33 passes through the monitoring hole 35 and is recognized by the infrared receiver 34. The adjustment plate 31 is provided with a through hole 38 for monitoring the movement of the monitoring rod 32. The monitoring rod 32 is elastically arranged in the through hole 38. The infrared receiver 34 triggers the refreshing component to work after receiving the signal of the infrared transmitter 33 within the set time without passing through the set number of times. The side wall of the monitoring rod 32 is fixedly connected with a limiting block 36, and the inner wall of the through hole 38 is provided with a limiting groove 37. The two ends of the limiting groove 37 are closed. The limiting block 36 and the limiting groove 37 are also fixedly connected with elastic parts to achieve the elastic effect of the monitoring rod 32.

[0043] The setting component includes a collection box 39 arranged at the bottom of the water filter box 10, an upper box 40 arranged at the bottom of the collection box 39, a setting pipe 41, a lower box 42, a water level sensor 43 and an adjustment part for changing the flow of the setting pipe 41, the upper box 40 is used to receive water in the collection box 39, the setting pipe 41 is set as a hose and is used to connect the upper box 40 and the lower box 42, the water level sensor 43 is set at the top of the lower box 42, the infrared receiver 34 is electrically connected to the setting electric push rod 49, the setting electric push rod 49 is fixedly connected to the setting rod 50, the adjustment box 20 is fixedly connected to the proximity switch 51, and the proximity switch 51 controls the operation of the fresh component; the water inlet of the collection box 39, the water inlet and water outlet of the upper box 40, the lower box 42 Solenoid valves are provided at the water inlet and outlet of the box 42. The adjustment part includes an adjusting block 44, a threaded rod 45 and an adjusting wheel 46 fixed on the lower box 42. The adjusting block 44 is provided with a vertical hole 47 for the setting tube 41 to pass through, and the adjusting hole is provided with a horizontal hole 48. The vertical hole 47 and the horizontal hole 48 are perpendicular to each other and interconnected. The threaded rod 45 is threadedly connected to the horizontal hole 48, and the adjusting wheel 46 is rotatably connected to the threaded rod 45. The flow rate of the setting tube 41 is controlled according to the floating time collected by the staff in the adjustment box 20. After rotating the threaded rod 45, the adjusting wheel 46 moves toward the setting tube 41 and squeezes and deforms the setting tube 41, thereby controlling the flow rate of water dripping from the setting tube 41.

[0044] The proximity switch 51 is connected to the nozzle through a PLC controller, and the setting electric push rod 49 is controlled by the infrared receiver 34. Only when the infrared receiver 34 does not receive the signal from the infrared transmitter 33, the setting electric push rod 49 will be controlled to move. First, the flow of the setting tube 41 is controlled. The flow of the setting tube 41 can be controlled by rotating the threaded rod 45. At this time, the water outlet of the upper box 40 and the water inlet of the lower box 42 need to be opened, and the water inlet of the upper box 40 and the water outlet of the lower box 42 need to be closed. The water in the upper box 40 begins to enter the lower box 42 through the setting tube 41. After the water in the upper box 40 completely enters the lower box 42, the water level sensor 43 can recognize that the water level has been reached. The set time; in this process, as the ventilation frame 23 rises, the monitoring rod 32 is lifted and moves upward, and the monitoring hole 35 on the monitoring rod 32 moves upward. At this time, the infrared receiver 34 cannot receive the signal of the infrared transmitter 33. At this time, the infrared receiver 34 controls the movement of the setting electric push rod 49, and the setting electric push rod 49 controls the setting rod 50 to move toward the proximity switch 51. If the time is reached, the movement of the setting electric push rod 49 stops at this time, regardless of whether the subsequent ventilation frame 23 moves upward, it will not trigger the movement of the setting electric push rod 49; and at this time, the setting rod 50 has not reached the position of the proximity switch 51, which proves that the number of ventilations is not enough, and the deodorant needs to be released to deodorize the floating objects in the adjustment box 20.

[0045] The implementation principle of the multi-stage pond joint control wetland water quality enhancement purification system of the embodiment of the present application is as follows: the top of the water filter box 10 is set as an opening and the lowest position of the bottom frame 5 just moves to be flush with the plane of the opening of the water filter box 10, and then when the frame 4 moves to the specified position, the floating objects fall into the water filter box 10, and the floating objects that fall into the water filter box 10 begin to filter water under the action of the water filter plate 11. The volume of the water filter box 10 is much larger than the volume of the frame 4, so the side of the water filter box 10 away from the frame 4 is set as an opening, but the floating objects will not fall; the squeezing plate 13 squeezes out water from the floating objects in the water filter box 10. After the squeezing plate 13 squeezes the floating objects for a period of time, the adsorption component 14 is controlled to start moving and move in contact with the lower wall of the water filter plate 11. If the floating objects When there is still residual moisture, the adsorption component 14 adsorbs the moisture during the movement. Of course, the adsorption component 14 can also be controlled to move multiple times, and then the adsorption component 14 is transported to the inspection cavity 16, and the adsorption component 14 is continued to be squeezed. If the adsorption component 14 adsorbs moisture, but no obvious moisture is squeezed out when the adsorption component 14 is squeezed, the water sensor 17 does not recognize the moisture at this time. Of course, it is also possible that the adsorption component 14 does not adsorb moisture, and the water sensor 17 does not recognize the moisture at this time; and when there is water in the water filter plate 11, the adsorption component 14 begins to absorb moisture. During the squeezing process, the moisture is squeezed out and falls into the inspection cavity 16. The moisture begins to flow along the inspection cavity 16 and flows to the position of the water sensor 17, proving that the floating objects still need to be drained.

[0046] In the initial state, the contact piece 26 contacts the blades of the impeller 25, and the torsion spring is in a deformed state, so that the contact piece 26 contacts the blades of the impeller 25. At this time, the trigger hole 30 is in an open state, and the light sensor 29 can identify the light source 27. Only when the speed of the impeller 25 is faster, the blades of the impeller 25 can convey the contact piece 26 into the trigger hole 30. As long as the speed of the impeller 25 is fast enough, it proves that the external wind force is strong. When the blades of the impeller 25 contact the contact piece 26 and the contact piece 26 is directed toward the trigger hole 30, the contact piece 26 will be moved to the trigger hole 30. During squeezing, the next blade rotates to the position of abutting the abutting piece 26 before the abutting piece 26 swings downward, and the abutting piece 26 is always in the trigger hole 30 and blocks the trigger hole 30. When the light sensor 29 does not recognize the light source 27, it proves that the external wind force is strong enough, and the ventilation frame 23 can be opened. The ventilation frame 23 is pulled to the outside of the regulating box 20. At this time, the odor in the regulating box 20 can be dispersed. If the wind force is not strong enough, the ventilation hole 21 will not be opened to prevent other impurities from entering the regulating box 20.

[0047] First, the flow rate of the setting tube 41 can be controlled by rotating the threaded rod 45. At this time, the water outlet of the upper box 40 and the water inlet of the lower box 42 need to be opened, and the water inlet of the upper box 40 and the water outlet of the lower box 42 need to be closed. The water in the upper box 40 begins to enter the lower box 42 through the setting tube 41. After the water in the upper box 40 completely enters the lower box 42, the water level sensor 43 can recognize that the set time has been reached. In this process, as the ventilation frame 23 rises, the monitoring rod 32 is lifted and moves upward, and the monitoring rod 32 is lifted and moves upward. The monitoring hole 35 moves upward. At this time, the infrared receiver 34 cannot receive the signal from the infrared transmitter 33. At this time, the infrared receiver 34 controls the setting electric push rod 49 to move, and the setting electric push rod 49 controls the setting rod 50 to move toward the proximity switch 51. If the time is reached, the movement of the setting electric push rod 49 stops at this time. Regardless of whether the subsequent ventilation frame 23 moves upward, it will not trigger the setting electric push rod 49 to move; and at this time, the setting rod 50 has not reached the position of the proximity switch 51, which proves that the number of ventilations is not enough and the deodorant needs to be released to deodorize the floating objects in the adjustment box 20.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
