Referring to fig. 1 to 5, a manhole malodor prevention device 100 according to the present embodiment is applied to a manhole covered with a grill 10 at an upper portion and communicating with a pipe, the manhole malodor prevention device 100 including a malodor prevention casing part 110 and a malodor blocking part 120.
The grill 10 includes a peripheral edge 11 forming a periphery and an inner division 12 formed in a lattice shape inside the peripheral edge 11.
In the present embodiment, the grating 10 is shown as a rectangular parallelepiped, but it is an example, and of course, various forms may be proposed according to the form of the manhole.
The malodor preventing housing member 110 is disposed at a lower side of the grill 10 to communicate an outside of the grill 10 with the duct, and the malodor preventing housing member 110 includes a housing body 111 and an intermediate partition wall 112.
The case body 111 is formed to penetrate in the vertical direction, and in this embodiment, a rectangular box shape with an upper end and a lower end opened is given as an example.
The intermediate partition wall 112 is divided across the center portion of the case body 111, and the intermediate partition wall 112 is formed in a plate shape integrally across the center portion of the case body 111 in the longitudinal direction of the case body 111, thereby dividing the inner space of the case body 111 into two.
Reference numeral 113 is a grill mounting flange extending along the upper end of the case body 111 toward the peripheral direction with a certain width.
Reference numeral 114 denotes a shaft penetration hole formed through the case body 111 so as to rotatably penetrate a malodor blocking shaft 121 described later.
The shaft through holes 114 are respectively formed in two on each side of the casing body 111 so as to be symmetrical to each other with respect to the intermediate partition wall 112.
The malodor blocking member 120 is disposed inside the malodor preventing housing member 110 such that rainwater (rain water) flowing from the outside of the grill 10 flows through the malodor preventing housing member 110 into the duct by its own weight (self load) and blocks malodor from the duct from being emitted to the outside of the grill 10, and at the same time, when the duct is filled with the rainwater and the rainwater flows backward from the duct, the rainwater flowing backward can be discharged to the outside of the grill 10, and the malodor blocking member 120 includes a pair of malodor blocking rotary shafts 121 and a pair of malodor blocking blades 122.
The respective malodor blocking rotary shafts 121 are disposed to traverse the case body 111 to be parallel to the intermediate partition walls 112, respectively, and are disposed to be symmetrical to each other with the intermediate partition walls 112 therebetween, and the respective malodor blocking rotary shafts 121 are rotatably coupled to the case body 111 by penetrating the rotary shaft penetrating holes 114.
The respective malodor blocking blades 122 extend toward both sides of the respective malodor blocking rotary shafts 121, and are formed in a plate shape extending toward both sides of the respective malodor blocking rotary shafts 121 with a certain area. That is, each of the malodor blocking blades 122 is formed in a rectangular plate shape, and the malodor blocking rotary shafts 121 penetrate through the middle of each of the malodor blocking blades 122 in the longitudinal direction of each of the malodor blocking blades 122.
One side end of each of the malodor blocking blades 122 is in contact with a lower portion of one of the case body 111 and the intermediate partition wall 112, and the other side end of each of the malodor blocking blades 122 is in contact with an upper portion of the other of the case body 111 and the intermediate partition wall 112, whereby each of the malodor blocking blades 122 is obliquely disposed in an inclined form between the case body 111 and the intermediate partition wall 112 to block the space between the case body 111 and the intermediate partition wall 112 in an inclined form, whereby malodor from the duct is blocked by the malodor blocking member 120 from being emitted to the outside of the grill 10.
Preferably, each lower end of the each malodor blocking vane 122 is in contact with the lower portion of the intermediate partition wall 112, and each upper end of the each malodor blocking vane 122 is in contact with the upper portion of the casing body 111, whereby the each malodor blocking vane 122 is obliquely arranged in an inclined form to gradually descend from the casing body 111 toward the intermediate partition wall 112, so that the each malodor blocking vane 122 blocks between the casing body 111 and the intermediate partition wall 112 in an inclined form in a V-shape, whereby malodor from the duct is divided and accommodated in each lower side space of the each malodor blocking vane 122 divided from each other, whereby the rising force of the malodor can be relatively weakened.
The edge portions of the respective malodor blocking vanes 122 are formed of a relatively soft material such as a silicone rubber, so that the respective malodor blocking vanes 122 do not rub against the intermediate partition wall 112 and the case body 111.
The rainwater flowing from the outside of the grill 10 flows down along the inclined upper surfaces of the respective malodor blocking blades 122 to be collected on the inclined lower upper surfaces of the respective malodor blocking blades 122, and when the rainwater collected on the inclined lower upper surfaces of the respective malodor blocking blades 122 is collected to a certain amount or more, the respective malodor blocking blades 122 are rotated by the self weight of the rainwater to make the lower portions of the respective malodor blocking blades 122 face the pipe, and at the same time, the case body 111 and the intermediate partition wall 112 are opened therebetween, so that the rainwater can flow into the pipe.
In addition, in the present embodiment, when the rainwater fills the pipe and the rainwater flows backward from the pipe, the rainwater flowing backward from the pipe lifts the inclined upper bottom surface of each of the malodor blocking blades 122 so that each of the malodor blocking blades 122 rotates to orient the lower portion of each of the malodor blocking blades 122 toward the pipe, and at the same time, the case body 111 and the intermediate partition wall 112 are opened therebetween, so that the rainwater flowing backward from the pipe can be discharged to the outside of the grill 10.
In one aspect, the malodor blocking member 120 includes a hooking portion 124 formed on an upper surface of the malodor blocking blade 122, and the manhole malodor prevention device 100 may include a locking member 130 connecting the grill 10 and the hooking portion 124.
The hooking portion 124 is formed at a portion of the upper surface of the malodor blocking blade 122, which is located relatively to the upper side with respect to the malodor blocking rotary shaft 121.
As an example, the hooking portion 124 may be formed of a shape protruding in a ring shape on the upper surface of the malodor blocking blade 122.
Specifically, the locking member 130 includes a grill locking portion 131 locked to the grill 10, a hook portion 133 hung on the hanging portion 124, and an elasticity providing connection portion 132 that connects the grill locking portion 131 and the hook portion 133 and provides elasticity.
The grill locking portion 131 and the hooking portion 133 are formed in a hook shape so as to be capable of being hooked on the grill 10 and the hooking portion 124, respectively, and the elastic providing connection portion 132 may be formed in a tension spring shape.
The grill 10 and the hooking portion 124 are connected by the locking member 130, so that the rotation state of the malodor blocking member 120 can be maintained, and thus the open state between the case body 111 and the intermediate partition wall 112 can be maintained continuously as needed.
As described above, the manhole malodor prevention device 100 includes the malodor prevention housing member 110 and the malodor blocking member 120, thereby preventing the malodor in the duct from flowing backward while allowing the rainwater to flow into the duct, and at the same time, when the rainwater fills the duct due to an excessive amount of precipitation, allowing the rainwater to flow backward from the duct, preventing the insect such as mosquito from dropping eggs in the duct.
Hereinafter, the operation of the manhole malodor prevention device 100 according to the present embodiment will be described with reference to the accompanying drawings.
First, before the rainwater is supplied more than a certain amount, as shown in fig. 2, both side ends of each of the malodor blocking blades 122 are inclined to be in contact with each of the case body 111 and the intermediate partition wall 112. In this way, the space between the casing body 111 and the intermediate partition wall 112 is blocked in an inclined state by the respective malodor blocking blades 122, whereby malodor from the duct is blocked by the malodor blocking member 120 from being emitted to the outside of the grill 10.
Then, the rainwater flowing in from the outside of the grill 10 flows down along the inclined upper surfaces of the respective malodor blocking blades 122 to be collected on the inclined lower upper surfaces of the respective malodor blocking blades 122, and when the rainwater collected on the inclined lower upper surfaces of the respective malodor blocking blades 122 is collected to a certain amount or more, as shown in fig. 3 and 4, the respective malodor blocking blades 122 are rotated by the self weight of the rainwater to make the lower portions of the respective malodor blocking blades 122 face the duct, and at the same time, the case body 111 and the intermediate partition wall 112 are opened therebetween, whereby the rainwater falls down to be able to flow into the duct.
On the other hand, as shown in fig. 2, both side ends of the respective malodor blocking blades 122 are inclined to be in contact with the respective case body 111 and the intermediate partition wall 112, and then the rainwater is filled in the pipe due to excessive rain or the like in a rainy season or the like, so that when the rainwater is reversed from the pipe, the rainwater reversed from the pipe lifts up the inclined upper bottom surface of the respective malodor blocking blades 122, whereby as shown in fig. 3 and 4, the respective malodor blocking blades 122 are rotated to make the lower portions of the respective malodor blocking blades 122 face the pipe, and at the same time, the case body 111 and the intermediate partition wall 112 are opened, whereby the rainwater reversed from the pipe can be discharged to the outside of the grill 10.

Hereinafter, a manhole malodor prevention device according to other embodiments of the present invention will be described with reference to the accompanying drawings. In the above description, the descriptions which are repeated with those already described in the first embodiment of the present invention are replaced with the above descriptions, and omitted here.
Fig. 6 is a cross-sectional view showing the construction of a manhole malodor prevention device according to a second embodiment of the present invention, fig. 7 is an enlarged view of a portion B illustrated in fig. 6, and fig. 8 is an enlarged view showing a state in which a malodor blocking member illustrated in fig. 7 is opened.
Referring to fig. 6 to 8 together, in the present embodiment, the malodor blocking member 220 includes a first elastic deformation body 225, a first contact portion 227, a second elastic deformation body 226, and a second contact portion 228.
In addition, in the present embodiment, the malodor preventing housing member 210 includes a housing main body 211, an upper extending body 215, and a lower extending body 216.
The first elastic deformation body 225 is formed inside the malodor preventing housing member 210 to gradually downward toward the duct, and is formed of rubber or the like so as to be elastically deformable.
The first contact part 227 is formed at a lower portion of the first elastic deformation body 225, and the first contact part 227 is formed of rubber or the like so as to be integrally formed with the first elastic deformation body 225.
The second elastic deformation body 226 is formed inside the malodor prevention housing member 210 to gradually downward toward the duct and is formed symmetrically to the first elastic deformation body 225, and the second elastic deformation body 226 is formed of rubber or the like so as to be elastically deformable.
The second contact portion 228 is formed at a lower portion of the second elastic deformation body 226, and the second contact portion 228 is formed of rubber or the like so as to be integrally formed with the second elastic deformation body 226.
The first elastic deformation body 225 and the second elastic deformation body 226 are configured to gradually gather each other as going down toward the pipe, so that the first elastic deformation body 225 and the second elastic deformation body 226 are integrally formed in a funnel shape, and as shown in fig. 6 and 7, the first contact portion 227 and the second contact portion 228 are maintained in a state of being in contact with each other by the elastic force of the first elastic deformation body 225 and the second elastic deformation body 226, whereby malodor from the pipe is blocked by the malodor blocking member 220 to prevent the malodor from being emitted to the outside of the grill.
The malodor blocking member 220 is formed as described above, whereby rainwater flowing in from the outside of the grill flows down along the respective upper surfaces of the first elastic deformation body 225 and the second elastic deformation body 226 to collect on the respective upper surfaces of the first elastic deformation body 225 and the second elastic deformation body 226, and when the rainwater collected on the respective upper surfaces of the first elastic deformation body 225 and the second elastic deformation body 226 collects to a certain amount or more, as shown in fig. 8, the deformed first elastic deformation body 225 and second elastic deformation body 226 are elastically deformed by the self weight of the rainwater, and at the same time, the first contact portion 227 and the second contact portion 228 are spaced apart from each other, whereby the case main body 211 becomes an open state, so that the rainwater can drop and flow into the duct.
When the pipe is filled with the rainwater and the rainwater flows backward from the pipe, the rainwater flowing backward from the pipe pressurizes the first elastic deformation body 225 and the second elastic deformation body 226 upward, and simultaneously, the first elastic deformation body 225 and the second elastic deformation body 226 are elastically deformed, so that the first contact portion 227 and the second contact portion 228 are spaced apart from each other, whereby the case body 211 is opened, and the rainwater flowing backward from the pipe can be discharged to the outside of the grill.
The case body 211 is formed to penetrate in the vertical direction.
The upper extension 215 extends toward the inside of the case body 211 by a certain length at the inner surface of the case body 211, and the upper extension 215 extends perpendicularly from the inner surface of the case body 211.
The lower extension 216 extends toward the inside of the case body 211 by a certain length at the inner surface of the case body 211, and is formed in parallel to be spaced apart from the upper extension 215 by a certain interval.
One end portion of the first elastic deformation body 225 and the second elastic deformation body 226 is interposed between the upper extension body 215 and the lower extension body 216, so that the malodor blocking member 220 can be fixed at the malodor preventing housing member 210.
When three or more of the malodor blocking members 220 are applied to the inside of the malodor prevention housing member 210, of the three or more of the malodor blocking members 220, the distal end portions of one of the first elastic deformation bodies 225 and the second elastic deformation bodies 226 of the two malodor blocking members 220 existing at both outermost peripheries are each inserted between the upper extension body 215 and the lower extension body 216, and of the three or more of the malodor blocking members 220, the first elastic deformation bodies 225 and the second elastic deformation bodies 226 of the remaining malodor blocking members 220 adjacent to each other except for the two existing at both outermost peripheries constitute a form connected to each other. In this way, in the malodor blocking member 220, the opening occurs between the first contact portion 227 and the second contact portion 228 at a plurality of places, so that the falling of the rainwater or the reverse flow of the rainwater can be completed.
In one aspect, the manhole malodor prevention device according to the present embodiment further includes a lower detachment prevention member 240 and an upper detachment prevention member 250.
The lower escape prevention member 240 is coupled to the case body 211 and supports an upper bottom surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226 so as to be able to prevent the malodor blocking member 220 from escaping downward toward the duct side.
The lower escape prevention member 240 may be configured in a plate shape extending a certain length in an up-down direction so as to be capable of supporting an upper bottom surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226.
The upper escape prevention member 250 is coupled to the case body 211 and presses an upper surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226 to be able to prevent the malodor blocking member 220 from escaping upward toward the grill side.
The upper escape prevention part 250 includes: an upper detachment prevention link 251 connected to the case body 211 and made of a metal material; and an upper detachment prevention elastic body 252 formed of an elastic material such as rubber to surround the upper detachment prevention connecting body 251 and to be in contact with an upper surface of at least one of the first elastic deformation body 225 and the second elastic deformation body 226.
The upper escape prevention elastic body 252 is not in contact with the case body 211 but with the upper face of at least one of the first elastic deformation body 225 and the second elastic deformation body 226, whereby the upper escape prevention link 251 is not in direct contact with the upper face of at least one of the first elastic deformation body 225 and the second elastic deformation body 226, so that the upper face of at least one of the first elastic deformation body 225 and the second elastic deformation body 226 can be not damaged.

Hereinafter, the operation of the manhole malodor prevention device according to the present embodiment will be described with reference to the accompanying drawings.
First, before the rainwater is supplied by a certain amount or more, as shown in fig. 6 and 7, the first contact part 227 and the second contact part 228 are brought into contact with each other, so that the malodor blocking member 220 is brought into a closed state, whereby the malodor from the duct is blocked by the malodor blocking member 220 to prevent the malodor from being emitted to the outside of the grill.
Then, the rainwater flowing in from the outside of the grill flows down along the upper surface of the malodor blocking member 220 to be accumulated on the upper surface of the malodor blocking member 220, and when the rainwater accumulated on the upper surface of the malodor blocking member 220 is accumulated to a certain amount or more, as shown in fig. 8, the first contact portion 227 and the second contact portion 228 are released from contact by the self weight of the rainwater, so that the malodor blocking member 220 is opened, whereby the rainwater falls down to be able to flow into the pipe.
On the other hand, as shown in fig. 6 and 7, the malodor blocking member 220 is maintained in a closed state, and then when the rainwater is filled in the pipe due to excessive rain or the like in a rainy season or the like, causing the rainwater to flow backward from the pipe, the rainwater flowing backward from the pipe lifts up the malodor blocking member 220 downward, so that the contact of the first contact portion 227 and the second contact portion 228 is released and the malodor blocking member 220 is opened, whereby the rainwater flowing backward from the pipe can be discharged to the outside of the grill.

The elevation guide member 370 extends downward from the bottom surface of the malodor prevention housing member 310 by a predetermined length, and guides the elevation of the elevation member 380, and the elevation guide member 370 includes an elevation guide body 371, a sliding elevation hole 373, and an elevation connection hole 372.
The elevating guide 371 extends downward, i.e., vertically, from the bottom surface of the malodor prevention housing member 310 by a predetermined length.
The sliding lifting hole 373 is formed inside the lifting guide body 371 along a longitudinal direction of the lifting guide body 371, and the sliding lifting body 385 is lifted while being guided along the sliding lifting hole 373.
The elevation connection hole 372 is formed to extend vertically on a surface of the sliding elevation hole 373 facing the elevation body 381, and may elevate the elevation connector 384 in a penetrated state.
The malodor blocking side permanent magnet 365 is constituted by a pair so as to be coupled to each of the outer peripheries of the first contact portion 327 and the second contact portion 328 constituting the malodor blocking member 320, respectively, and is arranged to face each other with different polarities. For example, the N pole of the malodor blocking side permanent magnet 365 coupled to the outer periphery of the first contact portion 327 is disposed toward the contact surfaces of the first contact portion 327 and the second contact portion 328, and the S pole of the malodor blocking side permanent magnet 365 coupled to the outer periphery of the second contact portion 328 is disposed toward the contact surfaces of the first contact portion 327 and the second contact portion 328. In this way, the pair of the malodor blocking side permanent magnets 365 attract each other, so that the first contact portion 327 and the second contact portion 328 can maintain a state of contact with each other.
The elevating permanent magnet 360 is formed of a pair so as to be coupled to both end portions of the upper portion of the elevating body 381, which are opposed to each other in a spaced apart state, and the elevating permanent magnet 360 and the malodor blocking side permanent magnet 365 are opposed to each other to influence each other in a state where the elevating body 381 is relatively raised, and the elevating permanent magnet 360 and the malodor blocking side permanent magnet 365 are opposed to each other to not influence each other in a state where the elevating body 381 is relatively lowered.
The lifting permanent magnet 360 is configured to have a relatively stronger magnetic force than the malodor blocking side permanent magnet 365.
In the present embodiment, among the pair of lifting permanent magnets 360 and the pair of malodor blocking side permanent magnets 365, magnets each facing each other are arranged to have different polarities from each other. For example, when the N pole of the malodor blocking side permanent magnet 365 bonded to the outer periphery of the first contact portion 327 among the malodor blocking side permanent magnets 365 is disposed toward the contact surfaces of the first contact portion 327 and the second contact portion 328, the S pole of the malodor blocking side permanent magnet 365 bonded to the outer periphery of the second contact portion 328 among the malodor blocking side permanent magnets 365 is disposed toward the outer periphery of the first contact portion 327, the S pole of the lifting magnet 360 bonded to the outer periphery of the first contact portion 327 among the malodor blocking side permanent magnets 365 is disposed toward the contact surfaces of the first contact portion 327 and the second contact portion 328, and the N pole of the malodor blocking side permanent magnet 365 bonded to the outer periphery of the second contact portion 328 among the malodor blocking side permanent magnets 365 is disposed toward the outer periphery of the second contact portion 328, the N pole of the lifting magnet 360 opposing the outer periphery of the first contact portion 327 among the lifting permanent magnet 360 is disposed toward the first contact portion 327, and the S pole of the lifting magnet 360 opposing the outer periphery of the second contact portion 328 is disposed toward the second contact portion 328.
In the above configuration, as shown in fig. 9, in the state where the elevating body 381 is lowered, the elevating permanent magnet 360 and the malodor blocking side permanent magnet 365 are relatively spaced apart from each other, and thus the attractive force between the pair of malodor blocking side permanent magnets 365 relatively acts stronger than the attractive force between the elevating permanent magnet 360 and the malodor blocking side permanent magnet 365 to be opposed to each other, whereby the pair of malodor blocking side permanent magnets 365 are attracted to each other while the first contact portion 327 and the second contact portion 328 are maintained in a contact state, and the malodor blocking member 320 is in a closed state.
Then, when the water level in the pipe rises, as shown in fig. 10, in the state where the elevating body 381 rises, the elevating permanent magnet 360 and the malodor blocking side permanent magnet 365 relatively approach each other, so that the attractive force between the elevating permanent magnet 360 and the malodor blocking side permanent magnet 365 facing each other is relatively stronger than the attractive force between the pair of malodor blocking side permanent magnets 365, so that the elevating permanent magnet 360 and the malodor blocking side permanent magnet 365 facing each other are respectively attracted to each other, whereby the first contact portion 327 and the second contact portion 328 are respectively spaced apart in a direction of being relatively far from each other, and at the same time, the contact of the first contact portion 327 and the second contact portion 328 is released, so that the malodor blocking member 320 becomes an opened state.
Hereinafter, the operation of the manhole malodor prevention device according to the present embodiment will be described with reference to the accompanying drawings.
First, before the rainwater is supplied by a certain amount or more, as shown in fig. 9, the lifting member 380 maintains a lowered state, and the first contact portion 327 and the second contact portion 328 are brought into contact with each other by attraction between the pair of the malodor blocking side permanent magnets 365, so that the malodor blocking member 320 is brought into a closed state, whereby the malodor on the pipe is blocked by the malodor blocking member 320 and prevented from being emitted to the outside of the grill.
Then, the rainwater flowing in from the outside of the grill flows down along the upper surface of the malodor blocking member 320 to be accumulated on the upper surface of the malodor blocking member 320, and when the rainwater accumulated on the upper surface of the malodor blocking member 320 is accumulated to a certain amount or more, the first contact portion 327 and the second contact portion 328 are released from contact by the self weight of the rainwater, so that the malodor blocking member 320 is opened, whereby the rainwater falls down to be able to flow into the pipe.
On the other hand, the malodor blocking member 320 is maintained in a closed state, and then when the rainwater is filled in the pipe due to excessive rain or the like in a rainy season or the like, and the rainwater flows back from the pipe, the water level in the pipe rises, and as shown in fig. 10, the lifting member 380 is lifted while being guided by the lifting guide member 370, whereby the respective lifting permanent magnets 360 and the respective malodor blocking side permanent magnets 365 facing each other attract each other, and the contact of the first contact portion 327 and the second contact portion 328 is released, whereby the malodor blocking member 320 is brought into an opened state, and the rainwater flowing back from the pipe can be discharged to the outside of the grill.
Fig. 11 is a sectional view enlarged in a state where a flange opening and closing member constituting a manhole malodor prevention device according to a fourth embodiment of the present invention is closed, and fig. 12 is a sectional view enlarged in a state where the flange opening and closing member illustrated in fig. 11 is opened.
Referring to fig. 11 and 12 together, in the present embodiment, a flange penetration hole 495 is formed through a grill mounting flange 413, the grill mounting flange 413 extending along an upper end of a casing body 411 constituting a malodor preventing casing member by a certain width in an outer circumferential direction, and the manhole malodor preventing apparatus according to the present embodiment further includes a flange opening and closing member 490.
The flange opening and closing member 490 may open and close the flange perforation 495, and the flange opening and closing member 490 includes a flange opening and closing body 491 and a flange opening and closing elastic body 492.
The flange opening and closing body 491 may close or open the flange perforation 495 at the bottom surface of the flange perforation 495, and the flange opening and closing body 491 may be formed in a plate shape capable of covering the area of the flange perforation 495.
The flange opening/closing elastic body 492 connects the flange opening/closing body 491 and the grill mounting flange 413, and provides elasticity, and as an example of the flange opening/closing elastic body 492, a plate spring may be proposed.
With the above configuration, the flange opening/closing body 491 is normally kept closed by the flange opening/closing elastic body 492 as shown in fig. 11.
Then, when water is accumulated in the grill mounting flange 413 due to rain or the like, as shown in fig. 12, the flange opening and closing elastic body 492 is elastically deformed by the self weight of the water accumulated in the grill mounting flange 413, and at the same time, the flange opening and closing body 491 is lowered, whereby the flange perforation 495 is opened, so that the water accumulated in the grill mounting flange 413 can be discharged.
When the drain of the water accumulated in the grill mounting flange 413 is completed, the flange opening and closing body 491 is in a state of closing the flange perforation 495 again by the restoring force of the flange opening and closing elastic body 492.
Fig. 13 is a cross-sectional view of an enlarged part of the constitution of a manhole malodor prevention device according to a fifth embodiment of the present invention.
Referring to fig. 13, in the present embodiment, a shaft fixing sleeve 501 protrudes from a case body 511, so that a malodor blocking rotary shaft 521 is rotatably connected to the shaft fixing sleeve 501.
In addition, an axial elasticity providing unit 502 is connected to the malodor blocking rotary shaft 521, so that the malodor blocking rotary shaft 521 is maintained in a rotated state by the axial elasticity providing unit 502 to cause the malodor blocking vane 522 to block the case body 511 obliquely.
When the malodor blocking rotary shaft 521 is rotated to cause the malodor blocking vane 522 to open the case body 511, restoring force is accumulated at the shaft elasticity providing unit 502, and then the malodor blocking rotary shaft 521 is rotated again to the original position by the restoring force of the shaft elasticity providing unit 502, whereby the malodor blocking vane 522 maintains a state of blocking the case body 511 again obliquely.
As the shaft elasticity providing unit 502, a torsion spring may be proposed, in which the shaft elasticity providing unit 502 is in a state of being wound around the malodor blocking rotary shaft 521, one end of the shaft elasticity providing unit 502 is fixed to the malodor blocking rotary shaft 521, and the other end of the shaft elasticity providing unit 502 is fixed to the shaft fixing sleeve 501.
On the one hand, a shaft rotation limiting stopper 504 limiting the rotation range of the malodor blocking rotary shaft 521 is formed at the shaft fixing collar 501 to prevent the turning phenomenon of the malodor blocking vanes 522 occurring when the malodor blocking rotary shaft 521 is rotated beyond the vertical.
The shaft rotation limiting stopper 504 protrudes from the shaft fixing sleeve 501 by a certain length, passes through the center of the malodor blocking rotary shaft 521, and is disposed on a virtual line formed in the gravitational direction.
The rotation range of the malodor blocking rotary shaft 521 is limited by the shaft rotation limiting stopper 504 so that the malodor blocking blade 522 may not be turned over.
On the other hand, a weight 503 is further provided to the malodor blocking blade 522, so that the malodor blocking rotary shaft 521 maintains a rotated state by the weight of the weight 503 to cause the malodor blocking blade 522 to block the case body 511 obliquely.
While the present invention has been described with reference to the specific embodiments, it will be understood by those skilled in the art that various modifications and changes may be made without departing from the spirit and scope of the invention as set forth in the following claims. However, it should be understood that such modifications and variations are all included within the scope of the claims of the present invention.
