Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of public health deodorization equipment, and specifically relates to an automated deodorization device for public health environments. Background Technology
[0002] As a crucial component of urban infrastructure, the environmental quality of public restrooms directly impacts the public's experience and health safety. With accelerated urbanization, the frequency of use of public restrooms in densely populated areas such as shopping malls, transportation hubs, and hospitals has increased dramatically, making odor problems increasingly prominent. Restroom odors primarily originate from irritating gases such as hydrogen sulfide and ammonia produced by the decomposition of excrement, as well as bacterial metabolic products that thrive in damp environments. These odors not only cause discomfort but can also trigger respiratory irritation, allergic reactions, and other health problems.
[0003] Reference publication number CN213032207U discloses a deodorization device, specifically a high-efficiency and environmentally friendly deodorization device, including a housing, a gas inlet pipe installed on the housing, and a gas outlet installed on the housing. A partition is provided inside the housing, dividing the internal cavity of the housing into a first purification chamber and a second purification chamber. The first purification chamber is connected to the gas inlet pipe, and the second purification chamber is connected to the gas outlet. A vent hole is provided on the lower side of the partition to connect the first and second purification chambers. The first purification chamber contains, from top to bottom, a spray pipe, a porous support plate, and a biofilter bed. The deodorizing agent is fully mixed with the odorant for initial deodorization. The odor is then absorbed by microorganisms on the biofilter bed for a second purification. When the gas passes through an activated carbon drawer, the activated carbon further purifies the gas, greatly improving the purification efficiency and purity.
[0004] In the aforementioned patent, the purified gas is blown out from the gas outlet. Although the odor is purified, in actual use, even if the harmful components of the odor are removed, the lack of fragrance coverage will still leave a faint odor that will give users an unpleasant olfactory experience.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0006] In view of the problems in related technologies, this utility model proposes an automated deodorization device for public health environments to overcome the aforementioned technical problems existing in the existing related technologies.
[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model relates to an automated deodorization device for public health environments, comprising a device housing, a gas inlet pipe installed at one end of the device housing, an inlet fan, an ultraviolet germicidal lamp, and an activated carbon filter bed sequentially installed inside the device housing from the gas inlet pipe side, a gas outlet pipe installed at one end of the device housing, a placement mechanism provided inside the gas outlet pipe, symmetrically formed sliding grooves on the gas outlet pipe, an annular groove formed on the gas outlet pipe above the two sliding grooves, the annular groove communicating with the two sliding grooves, the placement mechanism located within the two sliding grooves, a movable PVC pipe threaded onto the outer wall of the gas outlet pipe, and a diffusion mechanism slidably installed on the top of the movable PVC pipe.
[0009] Furthermore, the placement mechanism includes a connecting ring located inside the gas outlet pipe, and sliders are symmetrically fixedly installed on the outer wall of the connecting ring, with the two sliders respectively located in the two sliding grooves.
[0010] Furthermore, a bearing plate is fixedly installed on the inner ring of the connecting ring, and multiple air vents are opened on the bearing plate. Three connecting rods are fixedly installed on the top of the connecting ring.
[0011] Furthermore, two of the connecting rods are symmetrically distributed, and the other connecting rod is disposed between the two symmetrical connecting rods.
[0012] Furthermore, a fixing ring is fixedly installed on the top of each of the three connecting rods, and a locking block is symmetrically fixedly installed on the top of each fixing ring.
[0013] Furthermore, a blocking block is installed at the top of the movable PVC pipe, and the diffusion mechanism includes a first PVC pipe with an anti-detachment block installed at the bottom of the first PVC pipe, and the movable PVC pipe is located inside the first PVC pipe.
[0014] Furthermore, a T-shaped PVC pipe is installed on the top of the first PVC pipe, and multiple second PVC pipes are linearly connected to both sides of the T-shaped PVC pipe.
[0015] Furthermore, multiple second PVC pipes are connected end to end, and each second PVC pipe is connected to a dispensing pipe.
[0016] This utility model has the following beneficial effects:
[0017] This invention relates to a solid aromatherapy block placed inside a placement mechanism located within a gas outlet pipe. As the gas exits through the outlet pipe, it flows over the surface of the solid aromatherapy block, accelerating the evaporation and diffusion of aroma molecules. This ensures that the purified gas exiting the outlet pipe carries the aroma, which is then dispersed into the public health environment. This achieves uniform aroma coverage throughout the space, effectively neutralizing residual odors and creating a fresh and pleasant atmosphere.
[0018] When the solid aromatherapy blocks on the placement mechanism are used up and new solid aromatherapy blocks need to be added, the operator first needs to manually pull the placement mechanism to move the corresponding part of the mechanism upwards along the two sliding grooves. The two sliding grooves guide the sliding of the placement mechanism until it reaches the annular groove. Since the two sliding grooves are connected to the annular groove, after the placement mechanism slides into the annular groove, it is then rotated to rotate circumferentially along the annular groove. That is, the corresponding part of the placement mechanism disengages from the two sliding grooves and is supported by the horizontal support surface of the annular groove. At this time, a new solid aromatherapy block is inserted. Then, the placement mechanism is rotated in the opposite direction to align with the two sliding grooves and slides downwards along the sliding grooves to reset, thus restoring the working state of the new solid aromatherapy block and realizing the addition of new solid aromatherapy blocks.
[0019] When it is necessary to expand the fragrance coverage area, the movable PVC pipe is threaded to the gas outlet, and its end is slidably engaged with the diffusion mechanism. The diffusion mechanism is fixed to the wall by a clamp and can be spliced and extended according to space requirements to cover the entire wall. The purified fragrant gas is introduced into the diffusion mechanism through the movable PVC pipe and then discharged from various areas within the diffusion mechanism, achieving large-area and uniform fragrance coverage and full fragrance coverage in public health spaces.
[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0032] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0033] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0034] Please see Figures 1-8As shown, this utility model is an automated deodorization device for public health environments, including a device housing 1. A gas inlet pipe 2 is installed at one end of the device housing 1, and a gas outlet pipe 3 is installed at the other end of the device housing 1. Inside the device housing 1, from the side of the gas inlet pipe 2, an inlet fan 10, an ultraviolet germicidal lamp 11, and an activated carbon filter bed 12 are installed in sequence. A placement mechanism 4 is provided inside the gas outlet pipe 3. Sliding grooves 6 are symmetrically opened on the gas outlet pipe 3. An annular groove 7 is opened on the gas outlet pipe 3 and above the two sliding grooves 6. The annular groove 7 communicates with the two sliding grooves 6. The placement mechanism 4 is located inside the two sliding grooves 6. A movable PVC pipe 8 is threadedly installed on the outer wall of the gas outlet pipe 3. A diffusion mechanism 9 is slidably installed on the top of the movable PVC pipe 8.
[0035] First, the equipment casing 1 is installed on the wall area of the public restroom that needs odor removal using bolts or screws. A dustproof net is installed on the equipment casing 1 and at the front end of the gas inlet pipe 2. Its mesh structure can intercept large particles of impurities such as dust and lint from the outside, preventing dust accumulation and blockage inside the equipment casing 1. When the deodorization program is started, the inlet fan 10 draws the odor from the restroom into the equipment casing 1 through negative pressure suction. First, it is irradiated by the ultraviolet germicidal lamp 11 to sterilize the bacteria in the air. Then, the airflow penetrates the activated carbon filter bed 12. The porous activated carbon particles inside the filter bed remove volatile odor molecules such as ammonia and hydrogen sulfide through physical adsorption. Finally, the purified gas is discharged from the gas outlet pipe 3. This is the prior art. For details, please refer to the utility model patent with publication number CN215166239U.
[0036] The solid aroma block is placed in the placement mechanism 4, which is located inside the gas outlet pipe 3. As the gas is discharged from the gas outlet pipe 3, the gas can flow over the surface of the solid aroma block. The airflow accelerates the volatilization and diffusion of the aroma molecules in the solid aroma block, so that the purified gas discharged from the gas outlet pipe 3 carries the aroma and is then dispersed into the public health environment, thereby achieving uniform fragrance coverage throughout the space, effectively neutralizing residual odors, and creating a fresh and pleasant environment.
[0037] When the solid aromatherapy blocks on the placement mechanism 4 are used up and new blocks need to be added, the operator first needs to manually pull the placement mechanism 4 to move the corresponding part of the mechanism 4 upwards along the two sliding grooves 6. The two sliding grooves 6 guide the sliding of the placement mechanism 4 until it reaches the annular groove 7. Since the two sliding grooves 6 and the annular groove 7 are connected, after the placement mechanism 4 slides into the annular groove 7, it is then rotated to rotate circumferentially along the annular groove 7. That is, the corresponding part of the placement mechanism 4 disengages from the two sliding grooves 6 and is supported by the horizontal support surface of the annular groove 7. Insert a new solid aromatherapy block, then rotate the placement mechanism 4 in the opposite direction to align it with the two slide grooves 6, and slide it down along the slide grooves 6 to reset it. This will restore the new solid aromatherapy block to its working state and allow for the addition of new solid aromatherapy blocks. It is important to note that before the purified air enters the placement mechanism 4, a heating module (not shown in the figure) is integrated at the front end of the gas outlet pipe 3. This module heats the airflow (usually controlled at 40-60℃) through an electric heating wire or a PTC thermistor. This allows the heated air to carry heat energy through the solid aromatherapy block, increasing the evaporation rate of the fragrance and accelerating the sublimation of the solid aromatherapy block under the action of heat energy.
[0038] When it is necessary to expand the aroma coverage (such as...) Figure 2 As shown, the movable PVC pipe 8 is threaded to the outlet of the gas outlet pipe 3, and its end is slidably engaged with the diffusion mechanism 9. The diffusion mechanism 9 is fixed to the wall by a clamp and can be spliced and extended according to space requirements to cover the entire wall. The purified aroma-laden gas is introduced into the diffusion mechanism 9 through the movable PVC pipe 8 and then discharged from various areas within the diffusion mechanism 9, achieving large-area and uniform coverage of the aroma and full coverage of the aroma in the public health space. It is important to note that when replacing the solid aroma block, the movable PVC pipe 8 needs to be unscrewed from the gas outlet pipe 3, and then the gas outlet pipe 3 needs to be pushed upwards. The gas outlet pipe 3 will then enter the diffusion mechanism 9, and the placement mechanism 4 can then be pulled out.
[0039] In one embodiment, the placement mechanism 4 includes a connecting ring 401 located inside the gas outlet pipe 3. Slider 402s are symmetrically fixedly installed on the outer wall of the connecting ring 401, and the two sliders 402s are respectively located in the two grooves 6.
[0040] The inner ring of the connecting ring 401 is fixedly installed with a bearing plate 403, and the bearing plate 403 is provided with multiple air vents 404. Three connecting rods 405 are fixedly installed on the top of the connecting ring 401.
[0041] Two of the connecting rods 405 are symmetrically distributed, and another connecting rod 405 is disposed between the two symmetrical connecting rods 405.
[0042] The top of each of the three connecting rods 405 is fixedly mounted with a retaining ring 406, and the top of the retaining ring 406 is symmetrically fixedly mounted with a locking block 407.
[0043] The outer diameter of the connecting ring 401 is adapted to the inner diameter of the gas outlet pipe 3. The symmetrically distributed sliders 402 are embedded in the slide groove 6. The slide groove 6 provides guidance for the movement of the sliders 402. When the airflow passes through the gas outlet pipe 3, the airflow can pass through the evenly distributed air outlet holes 404 on the support plate 403. Then the gas can flow over the surface of the solid incense block, so that the purified gas discharged from the gas outlet pipe 3 carries the fragrance and is then dispersed into the public health environment.
[0044] When the solid aromatherapy block needs to be replaced, the worker pulls up the two locking blocks 407 by hand. The two locking blocks 407 will drive the fixing ring 406 to move upward. Then the fixing ring 406 will drive the three connecting rods 405 to move. The three connecting rods 405 will drive the connecting ring 401 to move. The connecting ring 401 will cause the two sliders 402 to slide along the corresponding slide grooves 6 to the position of the annular groove 7. Then rotate the two locking blocks 407 about 60°, and the sliders 402 will enter the annular groove 7. The horizontal support surface of the annular groove 7 will be used for support. At this time, the bearing plate 403 will be fully exposed outside the gas outlet pipe 3. Then, a new solid aromatherapy block will be inserted. After the replacement is completed, rotate the two locking blocks 407 in the opposite direction, so that the two sliders 402 rotate along the annular groove 7 and are simultaneously aligned with the two slide grooves 6. Then push the two locking blocks 407 downward, and the sliders 402 will reach the bottom of the slide groove 6.
[0045] In one embodiment, for the aforementioned movable PVC pipe 8, a blocking block 801 is installed on the top of the movable PVC pipe 8, the diffusion mechanism 9 includes a first PVC pipe 901, an anti-detachment block 902 is installed at the bottom of the first PVC pipe 901, and the movable PVC pipe 8 is located inside the first PVC pipe 901.
[0046] The top of the first PVC pipe 901 is equipped with a three-way PVC pipe 903, and multiple second PVC pipes 904 are linearly connected to both sides of the three-way PVC pipe 903.
[0047] Multiple second PVC pipes 904 are connected end to end, and each second PVC pipe 904 is connected to a dispensing pipe 905.
[0048] The outer diameter of the movable PVC pipe 8 is smaller than the inner diameter of the first PVC pipe 901, allowing the movable PVC pipe 8 to enter the first PVC pipe 901 during movement. The anti-detachment block 902 at the bottom of the first PVC pipe 901 and the blocking block 801 at the top of the movable PVC pipe 8 ensure that they will not accidentally detach during sliding connection. When the purified aromatic gas enters the movable PVC pipe 8 from the gas outlet pipe 3, it then enters the first PVC pipe 901 from the movable PVC pipe 8. The three-way PVC pipe 903 connects to the first PVC pipe 901, and then the gas enters the three-way PVC pipe 903 from the first PVC pipe 901. Multiple second PVC pipes 904 are linearly connected on both sides, forming a... A connected linear distribution network is formed, with multiple second PVC pipes 904 connected end to end. This allows gas to enter from the tee PVC pipe 903, then flow into the second PVC pipes 904 on both sides, and then into another second PVC pipe 904 connected to it. This process gradually enters each second PVC pipe 904. Each second PVC pipe 904 is connected to a diffuser pipe 905. The aroma-laden gas is ejected from the diffuser holes of the diffuser pipe 905. By setting the aroma-laden gas to be discharged from the diffuser pipes 905 on multiple second PVC pipes 904, a large-area and uniform aroma coverage is achieved, realizing full coverage of the aroma in the public health space.
