Description

Technical Field

[0001] This invention relates to the field of waste collection technology, and in particular to a device for collecting kitchen waste. Background Technology

[0002] Food waste contains high levels of organic matter and moisture, making it prone to rotting, bacterial growth, and foul odors. This is especially true in the kitchens of large restaurants and canteens, where the volume of food waste is high and the temperature is also high. If not cleaned promptly, food waste is more likely to produce unpleasant odors under these conditions. These odors not only attract insects but can also negatively impact food hygiene and kitchen cleanliness.

[0003] Some existing technologies reduce odor generation through solid-liquid separation. This is achieved by installing filters or liquid collection bins within the collection containers to keep solid waste relatively dry, thus reducing the likelihood of rotting and foul smells. However, these solutions only address the issue of accelerated decay due to solid-liquid mixing; they lack proactive measures to treat the already generated odor gases. Furthermore, some existing technologies include sealing lids to isolate the waste from the outside environment. However, when the lids are opened, the accumulated odors inside the bins still dissipate instantly, severely impacting the surrounding environment.

[0004] Therefore, a kitchen waste collection device is provided to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a kitchen waste collection device to address the shortcomings of existing technologies, thereby solving the technical problem that kitchen waste easily emits odors after collection.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A kitchen waste collection device includes an outer shell, a top frame and a base respectively installed at the top and bottom of the outer shell, the top of the top frame is formed with a funnel-shaped inlet and a cover for rotatably covering the inlet, one end of the cover is hinged to the top frame via a hinge shaft. The interior of the outer shell is fixed with a pair of left and right supporting plates. Between the two supporting plates is a solid waste collection frame that is put into the inlet and used to collect solid waste. At the bottom of the solid waste collection frame is a liquid waste collection frame for collecting waste liquid. The support plate is equipped with a pair of front and rear arranged support rods for supporting the liquid waste collection box; the base is equipped with a cooling component for contacting the bottom outer side of the liquid waste collection box. When the support rods support the liquid waste collection box, the bottom outer side of the liquid waste collection box contacts the cooling component. The outer shell is also equipped with a deodorizing component for deodorizing the collected kitchen waste, and a connecting component is installed on the support plate on the right side to connect the deodorizing component with the interior of the solid waste collection box.

[0007] The beneficial effects of this invention are as follows: First, the liquid waste collection frame is detachably installed at the bottom of the solid waste collection frame. Then, the solid and liquid waste collection frames, installed together, are inserted into the interior of the outer casing from top to bottom through the inlet, and placed between two supporting uprights. After food waste is placed into the inlet, it enters the solid waste collection frame. The solid and liquid waste collection frames are designed to be inserted and removed as a single unit from the inlet, making cleaning very simple. The waste can be lifted out as a whole without disassembling complex internal pipelines, facilitating daily disposal and maintenance. Furthermore, by setting up the solid and liquid waste collection frames, solid-liquid separation of food waste is achieved.

[0008] Furthermore, by installing support rods, both the solid waste collection bins and the liquid waste collection bins can be supported simultaneously. This not only ensures that both are placed in the designated positions but also prevents the liquid waste collection bin from detaching from the bottom of the solid waste collection bin due to the weight of the liquid waste, thus preventing tipping. Moreover, when the combined solid and liquid waste collection bins are in place, the bottom outer side of the liquid waste collection bin can make close contact with the cooling component. When the collection device is in operation or in standby mode, the cooling component activates cooling, directly absorbing heat from the waste liquid inside the liquid waste collection bin through contact heat conduction, keeping the internal liquid waste at a relatively low temperature, thereby fundamentally slowing down the activity of organic matter in the liquid. Direct cooling of the waste liquid inside the liquid waste collection bin by the cooling component significantly reduces heat accumulation, not only reducing the volatilization rate and dissipation of odor molecules (such as amines and sulfides) but also effectively inhibiting the reproduction and fermentation rate of putrefactive bacteria in the liquid waste, slowing down the deterioration process of the liquid, and significantly improving the air quality in the food waste storage area.

[0009] Next, the solid waste collection bins and liquid waste collection bins, installed together, are placed inside the outer casing and supported by the support rod. The connecting component is then activated, connecting to the solid waste collection bins to create a physical airflow path between the air inlet of the deodorizing component and the internal space of the solid waste collection bins. Once connected, the exhaust system inside the deodorizing component activates, using the generated negative pressure to actively extract the volatile odorous gases accumulated inside the solid waste collection bins, generated by the decomposition of kitchen waste, and direct them to the purification unit of the deodorizing component for further adsorption or decomposition.

[0010] The deodorizing component's air extraction and deodorizing effect, along with the cooling component's physical cooling effect, work together to suppress the odor emitted by kitchen waste through temperature control and gas circulation. This fundamentally changes the situation where odors are emitted into the external environment, thus improving the environmental and hygiene level of the equipment. Attached Figure Description

[0024] The following is a detailed description of a kitchen waste collection device according to the present invention, with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, an embodiment of the kitchen waste collection device of the present invention includes a housing 1, with a top frame 12 and a base 11 respectively installed at the top and bottom of the housing 1. The top of the top frame 12 is formed with a funnel-shaped inlet 15 and a cover 13 rotatably provided for covering the inlet 15. One end of the cover 13 is hinged to the top frame 12 through a hinge shaft. When the collection device is not in use, the inlet 15 is covered by the cover 13.

[0026] Inside the outer casing 1, a pair of left-right oriented support plates 16 are fixedly installed. Between the two support plates 16, a solid waste collection frame 2 is placed, which is inserted through the inlet 15 to collect solid waste. At the bottom of the solid waste collection frame 2, a liquid waste collection frame 3 is installed to collect waste liquid. First, the liquid waste collection frame 3 is detachably installed at the bottom of the solid waste collection frame 2. Then, the solid waste collection frame 2 and liquid waste collection frame 3, installed together, are inserted from top to bottom through the inlet 15 into the outer casing 1 and placed between the two support plates 16. After kitchen waste is deposited into the inlet 15, the kitchen waste enters the solid waste collection frame 2. The solid waste collection frame 2 and liquid waste collection frame 3 are designed to be inserted and removed as a single unit from the inlet 15, making cleaning very simple. The waste can be removed as a whole without disassembling complex internal pipelines, facilitating daily disposal and maintenance. Furthermore, by setting up the solid waste collection frame 2 and liquid waste collection frame 3, solid-liquid separation of kitchen waste is achieved. How solid-liquid separation works will be detailed below.

[0027] In this embodiment, a stirring assembly 4 for agitating solid waste is installed inside the solid waste collection box 2. A drive assembly 5 for driving the stirring assembly 4 is installed on the support plate 16 on the left side. When the solid waste collection box 2 is placed between the two support plates 16, the drive assembly 5 is connected to the stirring assembly 4. The stirring assembly 4 agitates the solid waste so that residual liquid can flow into the liquid waste collection box 3.

[0028] The support plate 16 is provided with a pair of support rods 6 arranged in front and behind for supporting the liquid waste collection box 3. By setting the support rods 6, the solid waste collection box 2 and the liquid waste collection box 3 can be supported at the same time. This not only ensures that both are placed in the designated position, but also prevents the liquid waste collection box 3 from detaching from the bottom of the solid waste collection box 2 due to excessive weight of the liquid waste, thus preventing it from tipping over.

[0029] The base 11 is equipped with a cooling component 7 for contacting the bottom outer side of the liquid waste collection box 3. When the support rod 6 supports the liquid waste collection box 3, the bottom outer side of the liquid waste collection box 3 contacts the cooling component 7. The cooling component 7 cools down the liquid waste inside the liquid waste collection box 3, reducing the dispersion effect of odor molecules.

[0030] When the solid waste collection box 2 and liquid waste collection box 3 are placed in place, the bottom outer side of the liquid waste collection box 3 can be in close contact with the cooling component 7. When the collection device is in operation or in standby mode, the cooling component 7 starts to cool and directly absorbs the heat of the waste liquid in the liquid waste collection box 3 through contact heat conduction, so that the internal liquid waste is kept at a relatively low temperature, thereby fundamentally slowing down the activity of organic matter in the liquid.

[0031] By directly cooling the waste liquid in the liquid waste collection box 3 through the cooling component 7, the heat accumulation can be greatly reduced. This not only reduces the volatilization rate and dispersion of odor molecules (such as amines and sulfides), but also effectively inhibits the reproduction and fermentation rate of putrefactive bacteria in the liquid waste, slows down the process of liquid putrefaction and deterioration, and significantly improves the air quality in the kitchen waste storage area.

[0032] In addition, an odor-removing component 8 for deodorizing the collected kitchen waste is installed inside the outer casing 1. A connecting component 9 for connecting the odor-removing component 8 to the interior of the solid waste collection box 2 is installed on the support plate 16 on the right side. After the solid waste collection box 2 and liquid waste collection box 3 are placed together inside the outer casing 1 and supported by the support rod 6, the connecting component 9 is activated. The connecting component 9 connects with the solid waste collection box 2, so that its interior is connected to the odor-removing component 8. The odor emitted by the kitchen waste inside the solid waste collection box 2 is absorbed by the odor-removing component 8 and then deodorized.

[0033] The connecting component 9, located on the right-side support plate 16, serves as an air passage hub. After the combined frame is in place, it moves inward or connects to the air inlet of the deodorizing component 8, enabling physical air passage between the air inlet and the internal space of the solid waste collection box 2. After connection, the ventilation system inside the deodorizing component 8 is activated. Using the generated negative pressure, it actively extracts the volatile odorous gases accumulated inside the solid waste collection box 2, which are produced by the decomposition of kitchen waste, and directs them to the purification unit of the deodorizing component 8 for subsequent adsorption or decomposition.

[0034] Each support rod 6 is equipped with a lifting assembly 10 at both ends, which connects it to the support plate 16 for vertical movement. The support plate 16 on the right side is equipped with a linkage assembly 20 for transmitting power from the connecting assembly 9 to the support rod 6 to make it move. During the process of separating the connecting assembly 9 from the solid waste collection box 2, force is applied to the linkage assembly 20 to drive the support rod 6 on the lifting assembly 10 to move upward. The upward movement of the support rod 6 can drive the solid waste collection box 2 and the liquid waste collection box 3 to move upward together for a certain distance, so that the staff can take them out from the inside of the outer shell 1.

[0035] When the connecting component 9 separates from the solid waste collection box 2, the outward separation action of the connecting component 9 will simultaneously trigger the linkage component 20. The linkage component 20 transmits the power generated by this separation action to the support rods 6. Under the power drive, each support rod 6 moves upward as a whole. The support rods 6 move upward in sync, thereby lifting the combination of the solid waste collection box 2 and the liquid waste collection box 3, raising it upward a preset distance from the inside of the outer shell 1. This lifting action makes the top edge of the combined box protrude significantly, providing ample gripping space for the staff.

[0036] An openable door panel 14 is provided on the side of the outer casing 1. After opening the door panel 14, the deodorizing component 8 can be repaired or maintained. The bottom of the cover 13 is equipped with a cover plate 18 for covering the opening of the solid waste collection box 2. A filling pad 19 is provided on the side of the cover plate 18 that contacts the solid waste collection box 2. When the cover 13 covers the disposal opening 15, the cover plate 18 will cover the opening of the solid waste collection box 2. At this time, the filling pad 19 will fill the space between the cover plate 18 and the solid waste collection box 2 to achieve a sealing effect, preventing odors from leaking out from the gaps and preventing the breeding of mosquitoes.

[0037] like Figure 4-6 As shown, the solid waste collection frame 2 includes an upper collection frame 21 with a semi-circular bottom. A supporting lip 22 is provided around the top opening of the upper collection frame 21. A support platform 17 for supporting the supporting lip 22 is provided at the bottom of the inner side wall of the disposal port 15. While the support rod 6 supports the liquid waste collection frame 3, the supporting lip 22 rests on the support platform 17. The bottom of the upper collection frame 21 is formed with multiple leakage holes 23, and the side wall of the upper collection frame 21 is provided with an annular upper lip 24. The liquid waste collection frame 3 includes a lower collection frame 31. The top opening edge of the lower collection frame 31 is provided with a lower lip 32 for contacting the upper lip 24. The lower lip 32 is equipped with multiple latches 33 for locking it to the upper lip 24.

[0038] When kitchen waste is poured into the upper collection frame 21, the residual liquid automatically gathers along the arc-shaped bottom contour and drips directly into the lower collection frame 31 through the drain hole 23. When the upper collection frame 21 and the lower collection frame 31 are assembled, the lower lip 32 fits tightly against and supports the upper lip 24. Then, the operator operates the multiple latches 33 distributed on the lower lip 32 to mechanically lock the two into a stable whole component.

[0039] Additionally, a connecting pipe 25 for connecting to the connecting component 9 is provided on the outer side of the upper collection box 21 near the connecting component 9. The connecting component 9 is equipped with an isolation net 26 for isolating solid waste. In the path of the gas being drawn out by the deodorizing component 8, the isolation net 26 pre-installed at the pipe inlet plays a physical interception role, blocking the fine kitchen waste residue that may be rolled up during the negative pressure suction process outside the main air passage of the deodorizing component 8, allowing odor molecules to smoothly penetrate into the purification system.

[0040] The stirring assembly 4 includes a rotating rod 41 arranged laterally and rotatably disposed inside the upper collection frame 21. Both ends of the rotating rod 41 are connected to the side of the upper collection frame 21 by bearings 42. Multiple stirring rods 43 are mounted on the rotating rod 41. The end of the rotating rod 41 near the drive assembly 5 extends to the outside of the upper collection frame 21, and a driven gear 45 is mounted at this end. The driven gear 45 is used for transmission connection with the drive assembly 5.

[0041] The power generated by the drive component 5 directly drives the driven gear 45 to rotate. The driven gear 45 drives the rotating rod 41 to rotate laterally inside the upper collection frame 21. As the rotating rod 41 continues to rotate, multiple stirring rods 43 fixed on its rod body synchronously rotate around the axis, which powerfully turns and breaks up the kitchen waste accumulated in the upper collection frame 21.

[0042] In addition, a pair of sealing caps 44 are installed on the inner wall of the upper collection frame 21, which are respectively placed at both ends of the rotating rod 41. Each sealing cap 44 is provided with a sealing ring 46 between itself and the inner wall of the upper collection frame 21. The sealing ring 46 is used to prevent liquid from seeping out from the gap.

[0043] The drive assembly 5 includes a rotating shaft 51 rotatably mounted on the support plate 16 and arranged laterally along its axis. One end of the rotating shaft 51 is provided with a drive gear 53 for meshing with the driven gear 45, and the other end is provided with an upper sprocket 52. The driven gear 45 is located directly above the drive gear 53. The drive assembly 5 also includes a drive motor 54 mounted on the support plate 16. The output shaft of the drive motor 54 is provided with a lower sprocket 55. A chain 56 is wound around the lower sprocket 55 and the upper sprocket 52. The size of the upper sprocket 52 is larger than the size of the lower sprocket 55.

[0044] The drive motor 54 drives the lower sprocket 55 on its output shaft to rotate at high speed. The lower sprocket 55 transmits power to the upper sprocket 52 through the chain 56. Since the upper sprocket 52 is significantly larger than the lower sprocket 55, it achieves a speed reduction effect. The rotating shaft 51 synchronously transmits power to the drive gear 53 at its other end. When the support rod 6 accurately lifts the combined frame to the designated working position, the drive gear 53 meshes perpendicularly with the driven gear 45 located directly above it, thus smoothly transmitting the rotational torque to the entire stirring assembly 4.

[0045] The support rod 6 has a positioning groove 61 for accommodating the lower lip 32. When the support rod 6 supports the liquid waste collection frame 3, the lower lip 32 is positioned by the positioning groove 61. The lower lip 32 is placed in the positioning groove 61, and the groove structure provides a horizontal physical limit to the frame. In the power connection process, when the driven gear 45 and the driving gear 53 are not in the correct phase with their tooth grooves facing each other, the drive motor 54 starts and the driving gear 53 starts to rotate. Relying on the normal thrust of its continuously rotating tooth surface and the position restriction of the lower lip 32 by the positioning groove 61, the tooth tip of the driving gear 53 is forced to slide laterally along the tooth surface of the driven gear 45, thereby sliding the locked tooth tip into the tooth groove gap of the other, so that the driving gear 53 can automatically drive itself to mesh into place after rotating.

[0046] The cooling component 7 includes a heat-conducting pipe 71 arranged in a wavy, curved shape and fitted to the bottom of the lower collection frame 31. The two ends of the heat-conducting pipe 71 are respectively connected to an outlet pipe 72 and an inlet pipe 73. The heat-conducting pipe 71 is a copper pipe. The heat-conducting pipe 71, the outlet pipe 72, and the inlet pipe 73 are all used to guide the refrigerant. The base 11 is fixedly provided with a support sleeve 74. Parts of the outlet pipe 72 and the inlet pipe 73 are housed in the support sleeve 74. It also includes a pair of connecting pipes 75 that are respectively connected to the outlet pipe 72 and the inlet pipe 73. Both connecting pipes 75 are connected to a refrigeration device located outside this collection device.

[0047] The refrigerant flows from the inlet pipe 73 into the heat-conducting pipe 71, which is attached to the bottom of the lower collection frame 31. The heat-conducting pipe 71 is arranged in a wavy, curved pattern and serves as the core heat exchange unit. Its excellent copper material properties enable it to efficiently transfer heat from the cavity to the refrigerant flowing inside. After absorbing heat, the refrigerant then flows into the outlet pipe 72 and returns to the external refrigeration equipment through another connecting pipe 75, completing the cooling cycle.

[0048] like Figure 7-9 As shown, the deodorization component 8 includes an air pump 81 mounted on the base 11, with an air intake pipe 82 and an exhaust pipe 83 respectively connected to the air inlet and outlet ends of the air pump 81; it also includes a vertically arranged purification pipe 84 for purifying odors, with an odor purification component inside the purification pipe 84, the bottom end of the purification pipe 84 connected to the air intake pipe 82, and the top end of the purification pipe 84 connected to an n-shaped air guide pipe 85, one end of the air guide pipe 85 connected to the top end of the purification pipe 84, and the other end connected to a horizontally arranged extension pipe 86.

[0049] The connecting component 9 includes a movable sleeve 91 that is laterally movably fitted outside the extension tube 86 and used to connect with the connecting tube 25. An electric push rod 93, with its extension direction parallel to the movement direction of the movable sleeve 91, is mounted on the support plate 16 on the right side. An annular sealing edge 92 is provided around the end of the movable sleeve 91 near the connecting tube 25. The edge of the sealing edge 92 is fixedly connected to the end of the extension rod of the electric push rod 93. After the sealing edge 92 laterally movably fits over the connecting tube 25, the outer wall of the connecting tube 25 and the inner wall of the sealing edge 92 are interference-fitted.

[0050] The connecting pipe 25 can also be a flexible hose. When the driven gear 45 and the driving gear 53 cannot mesh, the upper collection frame 21 is tilted, and the sealing edge 92 can still cover the connecting pipe 25.

[0051] After the combined frame is lowered, the telescopic rod of the electric push rod 93 extends, driving the annular sealing edge 92 fixedly connected to its end to move laterally. As the sealing edge 92 moves forward, the movable sleeve 91 slides accordingly until the inner wall of the sealing edge 92 is tightly fitted with the outer wall of the connecting pipe 25. Physical locking and air passage are achieved by the interference fit of the annular structure.

[0052] After the air passage is opened, the suction pump 81 installed on the base 11 starts. The suction pump 81 draws air from the bottom of the purification tube 84 through the suction pipe 82 connected to its air inlet end, forming a negative pressure airflow from bottom to top inside the purification tube 84. Under the action of high negative pressure, the odor in the solid waste collection box 2 passes through the connecting pipe 25, the movable sleeve 91 and the horizontal extension pipe 86 in sequence, and then enters the n-shaped air guide pipe 85, which is guided to the top of the purification tube 84. The odor passes through the odor purification component inside the purification tube 84 from top to bottom, where it undergoes physical adsorption or chemical purification and decomposition. The purified clean gas is finally discharged to the outside of the outer shell 1 by the suction pump 81 through the exhaust pipe 83 connected to its air outlet end.

[0053] Furthermore, considering the potential errors in gear meshing during actual use, the connecting pipe 25 is designed as a flexible hose structure with a certain degree of flexibility. Even if the driven gear 45 and the driving gear 53 are slightly tilted due to insufficient placement accuracy, the sealing edge 92 can still smoothly complete the connection by utilizing the deformable characteristics of the hose under the push of the electric push rod 93, ensuring that the air extraction operation is not affected by the tilt.

[0054] In this embodiment, the lifting assembly 10 includes a fixed frame 101 fixedly mounted on the supporting plate 16. The fixed frame 101 has a vertically arranged guide rod 102 inside. The end of the support rod 6 is slidably mounted on the guide rod 102. A first spring 103 is wound around the guide rod 102. The first spring 103 is positioned above the support rod 6 and applies a downward force to it. The assembly also includes a connecting rod 104, with both ends of the connecting rod 104 fixedly connected to the ends of the non-support rod 6.

[0055] When the linkage component 20 pulls the support rod 6 upward, it must overcome the elastic force of the first spring 103. After the pulling action is completed, the restoring force of the first spring 103 will drive the support rod 6 to smoothly return downward along the guide rod 102. In addition, the connecting rod 104 extends laterally to rigidly fix the ends of the corresponding support rods 6 on both sides into one piece, so that the lifting and lowering movements on both sides are physically synchronized.

[0056] The linkage assembly 20 includes multiple fixing rods 201 disposed on the supporting upright plate 16. The length direction of the fixing rods 201 is parallel to the movement direction of the movable sleeve 91. It also includes a push rod 202 passing through the supporting upright plate 16. The push rod 202 is formed with a sliding connection part 203 that is laterally slidably connected to the fixing rods 201. A push block 94 is formed on the edge of the sealing edge 92. A contact part 205 for contacting the push rod 202 is formed on the end near the push block 94. The fixing rod 201 is wound with a second spring. Spring 204, the second spring 204 is placed on the side of the sliding connection 203 away from the support plate 16; the connecting rod 104 is provided with a fixing member 207 aligned with the top rod 202, the fixing member 207 is formed with a bevel 208 on the side near the top rod 202, and the end of the top rod 202 near the fixing member 207 is rotatably provided with a roller 206 for contacting the bevel 208; when the top rod 202 applies force to the fixing member 207, the roller 206 rolls on the bevel 208, and the fixing member 207 moves upward.

[0057] The initial state of the telescopic rod of the electric push rod 93 is the extended state. At this time, the movable sleeve 91 covers the connecting pipe 25. After the electric push rod 93 is operated to retract its telescopic rod, it drives the movable sleeve 91 to move away from the upper collection frame 21. After moving until it is completely separated from the connecting pipe 25, the telescopic rod of the electric push rod 93 continues to retract. When the stroke enters the second half, the push block 94 formed on the sealing edge 92 just abuts against the contact part 205 at the end of the top rod 202, thereby pushing the top rod 202 to move laterally along the fixed rod 201. During the lateral movement, the second spring 204 sleeved on the fixed rod 201 is compressed by the sliding connection part 203 and stores energy. As the push rod 202 continues to move laterally, the roller 206 at its end contacts and abuts against the inclined side 208 of the fixing member 207 on the connecting rod 104. Due to the wedge-shaped design of the inclined side 208, the thrust of the horizontal movement of the push rod 202 forces the roller 206 to roll upward on the inclined surface of the inclined side 208. This physical action efficiently converts the horizontal thrust into vertical upward lift, directly driving the fixing member 207 and its connected connecting rod 104 to rise upward, and finally the linkage support rod 6 pushes the combined frame a certain distance. By setting the linkage component 20 to achieve power transmission and conversion, the use of power components is reduced, which not only reduces the failure rate but also saves processing costs.

[0058] like Figure 10-11As shown, the purification tube 84 includes an upper fixed tube 841, a lower fixed tube 842, and an installation sleeve 843. The installation sleeve 843 is used to connect the bottom end of the upper fixed tube 841 and the top end of the lower fixed tube 842. The upper fixed tube 841 is equipped with a plurality of adsorption components 844 arranged at intervals from top to bottom. The adsorption components 844 are used to physically adsorb odor molecules. The lower fixed tube 842 is equipped with a plurality of deodorizing components 845 arranged at intervals from top to bottom. The deodorizing components 845 are used for chemical deodorization, changing the structure of odor molecules through chemical reaction, so that the odor becomes an odorless gas.

[0059] In this embodiment, the adsorption component 844 includes a first annular frame 8441 whose outer side wall is attached and fixed to the inner side wall of the upper fixed tube 841. The top and bottom of the first annular frame 8441 are provided with first breathable nets 8442. The interior of the first annular frame 8441 is filled with activated carbon 8443 placed between the two first breathable nets 8442.

[0060] When the negative pressure airflow generated by the air pump 81 passes through the purification pipe 84 from top to bottom, the multi-layer adsorption components 844 installed inside the upper fixed pipe 841 form the first physical interception layer. When the odor passes through the first breathable net 8442, the volatile odor molecules, tiny suspended particles and organic vapors in it are trapped by the large specific surface area of ​​the activated carbon 8443, thus achieving physical adsorption.

[0061] The residual trace gases after physical filtration then enter the lower fixed tube 842. In this area, the chemical medium carried inside the deodorizing component 845 neutralizes or undergoes an oxidation-reduction reaction with the odor molecules, directly destroying their original chemical structure and completely transforming the irritating compound into a colorless, odorless, and harmless gas, thus completing the entire process of deep chemical purification.

[0062] The deodorizing component 845 includes a second annular frame 8451 whose outer wall is fixedly attached to the inner wall of the lower fixed tube 842. A second breathable mesh 8452 is provided at the bottom of the second annular frame 8451. A deodorizing cotton 8453, supported by the second breathable mesh 8452, is placed inside the second annular frame 8451. The deodorizing cotton 8453 absorbs a chemical deodorizer (which may be zinc ricinoleate deodorizing liquid). When residual odor gas flowing through the upper physical adsorption layer passes through the second breathable mesh 8452, the stubborn odor molecules containing sulfur and nitrogen in the gas undergo a specific complexation reaction with the zinc ricinoleate attached to the pores of the deodorizing cotton 8453. Zinc ricinoleate destroys the functional groups of the odor molecules, converting them into non-volatile stable compounds, thereby completely eliminating the irritating odor gas, rather than simply masking it.

[0063] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0064] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
