Description

Technical Field

[0001] The invention relates to the technical field of deodorization of public hygiene spaces, in particular to a deodorization device for public hygiene spaces. Background Art

[0002] Public health spaces refer to places with dense traffic and health service functions, such as public toilets, hospitals, shopping malls, schools, and transportation hubs. These spaces are prone to odor due to large traffic, closed environment, and frequent use. At the same time, they are accompanied by problems such as high humidity, bacterial growth, and reduced air quality, which not only affect the user experience, but may also pose a threat to public health. Therefore, public health spaces urgently need to use deodorization devices, which can not only improve the comfort of the space, but also improve the sanitary environment and reduce the risk of airborne diseases by efficiently removing odors, inhibiting bacterial growth, regulating air humidity, and optimizing air quality, thereby ensuring the health and satisfaction of users.

[0003] Traditional deodorization devices for public health spaces mainly achieve deodorization effects through physical filtration, chemical adsorption, and odor masking. Common devices include activated carbon filters, ozone generators, photocatalytic equipment, and spray-type air fresheners. Activated carbon filters achieve deodorization by adsorbing odor molecules, but have limited effects on high-concentration or persistent odors; ozone generators use ozone to decompose odor molecules and sterilize, but excessive use may be harmful to health; photocatalytic technology degrades organic odor molecules through ultraviolet rays and catalysts, while inhibiting bacteria; and air fresheners mask odors by emitting fragrance, but cannot fundamentally remove the source of pollution. These traditional devices have their own characteristics, but they usually have problems such as short-term effects, high energy consumption, or high maintenance costs. It is difficult to meet the comprehensive deodorization and air purification needs in a complex public health environment.

[0004] Traditional deodorization devices for public sanitary spaces usually use physical adsorption materials such as activated carbon filters, which are effective against specific gases (such as hydrogen sulfide, ammonia and other odor molecules). However, such a setting is difficult to effectively cover residual odors, especially when the odor is not completely treated, the air in the space is prone to feel uncomfortable.

[0016] Preferably, a heat sink is fixedly connected to the top of the outer shell, and the heat sink is used to dissipate heat from the power supply.

[0017] Working principle: When the deodorization device for public health space needs to be used, first start the fan 2 to drive the external air to be transported to the inside of the filter bin through the grille plate and the air supply plate 1. At this time, the water flow inside the water storage tank is transported to the inside of the atomizing nozzle through the water pipe, so that the water flow is atomized and discharged to one side of the air supply plate 1 through the atomizing nozzle. At this time, the air dust is combined with the atomized water, thereby increasing the volume of dust in the air. Then, the air is transported to the inside of the filter plate through the trapezoidal guide plate. At this time, the air is effectively filtered through the filter plate. Then, after long-term use, pull the card block 2 to make the card block 2 rotate with the rotating shaft as the center of the circle, so that the card block 2 slides out of the outer wall of the filter bin, and the spring contracts at the same time, and then pulls the filter bin out of the inside of the air supply plate 1, so as to facilitate the cleaning of the filter plate. When installing, you only need to put the filter bin back to its original position. At this time, the rebound of the spring pushes the card block 2 to move to one side of the filter plate to limit the filter plate. Then the air guides the filtered air through the guide plate, so that the air is transported to the deodorizer through the guide channel and the one-way valve. The inside of the odor bin is effectively deodorized by the deodorizing liquid in the deodorizing liquid storage bin. After deodorization, the air is further filtered by the activated carbon filter plate. Finally, the deodorized air is transported to the inside of the air supply tube through the guide plate. In addition, the activated carbon filter plate after filtering the air replaces the air. Then, the fan 1 and the PTC ceramic heater are started. Then, the fan 1 drives the air to be transported to the top of the air supply tube. The air is heated by the PTC ceramic heater. The heated air continues to be transported to the inside of the slow air tube. Then, the flow rate of the air is slowed down by the diverter plate and the vortex tube inside the slow air tube. Finally, the air passes through the aromatherapy block to discharge the fragrance. In addition, the driving card block 1 cooperates with the ventilation cover and the hinge to realize the opening and closing of the air supply tube. Then, the driving rotating ring cooperates with the U-shaped connecting plate to drive the screw to rotate. Then, the threaded relationship between the screw and the threaded sleeve is cooperated with the limit plate to make the threaded sleeve slide inside the air supply tube with the rotation of the screw, thereby driving the aromatherapy block to move up and down, thereby facilitating the replacement of the aromatherapy block and ensuring long-term fragrance emission.

[0018] The present invention provides a deodorizing device for public sanitary spaces. It has the following beneficial effects:

[0019] 1. The present invention heats the air through the PTC ceramic heating element, and at the same time cooperates with the diverter plate and vortex tube of the slow wind tube to slow down the air flow rate, so that the air flows evenly through the aromatherapy block, thereby effectively releasing the fragrance and improving the air quality of the public health space. In addition, the aromatherapy block is driven up and down by the lifting component, the U-shaped connecting plate and the screw rod, and the stability and replacement of the aromatherapy block are achieved in cooperation with the limit plate, ensuring the long-term continuous emission of fragrance while facilitating later maintenance, solving the problem that the device is difficult to effectively cover the residual odor, making the air in the space easily uncomfortable.

[0020] 2. The present invention atomizes the water flow through an atomizing nozzle and releases it to one side of the air supply plate, so that the dust in the air combines with the atomized water, increasing the volume of the dust, thereby settling and treating the dust pollution. The air then enters the filter plate in the filter bin through the trapezoidal guide plate to further filter the dust and particulate matter to ensure the cleanliness of the air. The filter bin is equipped with a disassembly and assembly component, which can easily carry out the removal and cleaning of the filter material, reduce the difficulty of maintenance and extend the service life of the equipment.

[0021] 3. The present invention introduces the filtered air into the deodorization chamber by means of a guide plate and a guide channel, and deodorizes the air under the action of the deodorizing liquid storage chamber, thereby effectively removing odor molecules in the air. At the same time, the activated carbon filter plate further performs deep filtration on the air, adsorbs residual odor and harmful gases, and ensures that the exhausted air is clean and odorless. The device integrates multi-stage deodorization technology and cooperates with a one-way valve to control the air flow direction, which significantly improves the deodorization effect and meets the needs of efficient deodorization in public health spaces.

[0034] Example:

[0035] Please refer to the attached Figure 1 - Attachment Figure 6 , the embodiment of the present invention provides a deodorizing device for a public health space, comprising an outer shell 1, a power supply 2 is installed at the upper left corner of the inner part of the outer shell 1, an air supply tube 3 is connected to the pipe at the upper right corner of the inner part of the outer shell 1, a guide plate 4 is fixedly connected to the bottom of the air supply tube 3, a fan 5 is arranged above the guide plate 4, a PTC ceramic heating element 6 is fixedly connected to the lower side of the inner wall of the air supply tube 3, a slow wind tube 7 is fixedly connected to the middle part of the inner wall of the air supply tube 3, a slow wind assembly is arranged on the inner wall of the slow wind tube 7, and the slow wind assembly is used to reduce the air flow rate, a ventilation plate 15 is slidably connected to the inside of the air supply tube 3, a limit plate 16 is fixedly connected to the outer wall of the ventilation plate 15, and the outer wall of the limit plate 16 is slidably connected to the inside of the air supply tube 3, an aromatherapy block 17 is arranged on the upper surface of the ventilation plate 15, a lifting assembly is arranged inside the air supply tube 3, and the lifting assembly is used to drive the ventilation plate 15 to move up and down, and an opening and closing assembly is arranged on the upper surface of the outer shell 1, and the opening and closing assembly is used to open and close the air supply tube 3;

[0036] The lifting assembly includes a rotating ring 11, the outer wall of the rotating ring 11 is rotatably connected to the inside of the air supply tube 3, the lower surface of the rotating ring 11 is fixedly connected with a U-shaped connecting plate 12, the middle part of the U-shaped connecting plate 12 is fixedly connected with a screw rod 13, the outer wall of the screw rod 13 is threadedly connected with a threaded sleeve 14, and the outer wall of the threaded sleeve 14 is fixedly connected to the outer wall of the ventilation plate 15; the slow wind assembly includes a diverter plate 8, the outer wall of the diverter plate 8 is fixedly connected to the lower side of the inner wall of the slow wind tube 7, the inner wall of the slow wind tube 7 is fixedly connected with a vortex guide ring 10, and the inner wall of the vortex guide ring 10 is fixedly connected with a vortex tube 9; the opening and closing assembly includes a hinge 18, the outer wall of the hinge 18 is fixedly connected to the upper surface of the outer shell 1, the outer wall of the hinge 18 is fixedly connected with a ventilation cover 19, and the top of the outer shell 1 is rotatably connected with a block 20.

[0037] Specifically, the purified air is then guided into the interior of the air supply tube 3 through the guide plate 4. At this stage, in order to further optimize the air quality, the fan 5 and the PTC ceramic heater 6 are started. The fan 5 generates an airflow to transport the air to the top of the air supply tube 3. At the same time, the PTC ceramic heater 6 heats the air. The heated air temperature increases, which helps to enhance the volatilization of the aroma molecules in the aromatherapy block 17, thereby further improving the air quality. The heated air is transported to the interior of the slow air tube 7. In the slow air tube 7, the airflow is evenly distributed by the diverter plate 8 to ensure that the airflow covers the entire surface of the aromatherapy block 17. In addition, the vortex tube 9 decelerates the airflow through its internal structure to make the airflow more stable in the slow air tube 7. The deceleration and uniform distribution of the airflow ensure that the fragrance of the aromatherapy block 17 can be fully released. The air processed by the slow air tube 7 flows through the aromatherapy block 17 arranged on the ventilation plate 15. The hot air promotes The aroma components in the aromatherapy block 17 are uniformly volatilized, and finally, the clean air with fragrance is discharged from the air supply tube 3 to the public sanitary space, providing users with a fresh and comfortable air environment. When the aromatherapy block 17 needs to be replaced, the rotating ring 11 is driven, and the rotating ring 11 drives the U-shaped connecting plate 12 and the screw rod 13 to rotate. Through the threaded cooperation between the screw rod 13 and the threaded sleeve 14, the threaded sleeve 14 slides inside the air supply tube 3, thereby driving the ventilation plate 15 to move up and down. The up and down movement of the aromatherapy block 17 is not only convenient for users to replace it, but also can adjust the contact angle between the aromatherapy block 17 and the airflow, so as to further optimize the aroma release effect. In addition, by driving the card block 20 to cooperate with the ventilation cover 19 and the hinge 18, the user can easily realize the opening and closing operation of the air supply tube 3, which is convenient for comprehensive maintenance and cleaning of the inside of the device. At the same time, the device efficiently dissipates heat to the power supply 2 through the heat sink 43 to prevent the equipment from overheating due to long-term operation.

[0038] Please refer to the attached Figure 7 - Attachment Fig. 9A grille plate 21 is provided on one side of the outer wall of the outer shell 1, and a baffle plate 24 is provided on the side of the outer wall of the outer shell 1 away from the grille plate 21. An air supply plate 22 is fixedly connected to the lower left side of the inner wall of the outer shell 1, and a filter bin 23 is slidably connected to the inner wall of the air supply plate 22. A filter cover 24 is fixedly connected to one side of the inner wall of the filter bin 23, and a fan 25 is fixedly connected to the side of the inner wall of the filter bin 23 away from the filter cover 24. An atomization component is provided at the bottom of the inner wall of the outer shell 1, and the atomization component is used to improve the dust quality in the air. A trapezoidal guide plate 45 is fixedly connected to the inner wall of the filter bin 23, and a filter plate 27 is fixedly connected to the top and bottom of the filter bin 23. The outer wall of the filter plate 27 is fixedly connected to the air supply plate 28, and a disassembly and assembly is provided inside the air supply plate 22. The assembly and disassembly assembly is used to take and place the filter bin 23; the disassembly assembly includes a rotating shaft 33, both ends of the rotating shaft 33 are rotatably connected to the inside of the air supply plate 22, the outer wall of the rotating shaft 33 is fixedly connected to a block 24, the inside of the air supply plate 22 is fixedly connected to a baffle 1 37, the inside of the baffle 1 37 is slidably connected to a slide rod 36, one end of the slide rod 36 fits inside the block 24, and the outer wall of the slide rod 36 is provided with a spring 35; the atomization assembly includes a water storage tank 30, the lower surface of the water storage tank 30 is fixedly connected to the inner wall of the outer shell 1, the inside of the water storage tank 30 is fixedly connected to a water pipe 31, one side of the outer wall of the water pipe 31 is fixedly connected to the inside of the air supply plate 22, and the other side of the outer wall of the water pipe 31 is fixedly connected to an atomizing nozzle 32.

[0039] Specifically, first, start the fan 25, which generates a strong suction force to suck the external air into the device through the grille plate 21 set on one side of the outer shell 1. The grille plate 21 not only serves as an air inlet, but also blocks larger particles of dust and impurities, preventing the incoming air from carrying too many pollutants and affecting the operation of subsequent devices. After passing through the grille plate 21, the air is further guided by the air supply plate 1 22 to flow into the interior of the filter bin 23. The air supply plate 1 22 is reasonably designed to ensure the stability of the flow direction of the airflow and to ensure that the air can flow evenly into the filter bin 23. At the same time, the water in the water storage tank 30 is sucked into the filter bin 23 through the water pipe 31. The stored water is transported to the interior of the atomizing nozzle 32. The atomizing nozzle 32 utilizes efficient atomization technology to convert the transported water flow into extremely fine water mist particles. These water mist particles are evenly sprayed to one side of the air supply plate 22 and are fully mixed with the air entering from the grille plate 21. At this time, the dust particles in the air are fully combined with the atomized water to form larger dust particles, thereby significantly improving the quality of the dust, making it easier for the dust particles to be captured by the subsequent filter plate 27, and effectively reducing the concentration of suspended particles in the air. Subsequently, the air mixed with the water mist is guided to the trapezoidal guide plate 45, which further stabilizes the airflow. The filter 27 has the function of guiding the air flow and smoothly delivering the air to the filter plate 27 inside the filter bin 23. At the filter plate 27, the dust particles in the air are effectively intercepted. The filter plate 27 ensures that the dust and other pollutants are captured by physical filtration and porous design, and at the same time ensures that the purified air can pass smoothly. After long-term use, when the filter bin 23 and the filter plate 27 accumulate too many dust particles, they need to be cleaned and maintained. At this time, the user can pull the card block 24 located inside the air supply plate 22. The card block 24 rotates with the rotating shaft 33 as the center to realize the unlocking operation of the filter bin 23 and the air supply plate 22. While rotating, the spring 35 contracts, causing the second clamping block 34 to slide out from the outer wall of the filter bin 23, releasing its fixed state. Subsequently, the user can easily pull the filter bin 23 and take it out from the inside of the air supply plate 1 22, so that the filter plate 27 with more dust accumulation can be easily cleaned or replaced to ensure that the filtering function of the device remains efficient. After cleaning, the filter bin 23 is put back to the original position of the air supply plate 1 22, and the spring 35 recovers and rebounds under its elastic force, pushing the second clamping block 34 to move to one side of the filter plate 27 again, fixing the position of the filter bin 23, and realizing the limit of the filter plate 27, which greatly facilitates the user's operation and reduces the difficulty of maintenance.

[0040] Please refer to the attached Figure 1 - Attachment Figure 2 and attached Fig.10The inner wall of the outer shell 1 is provided with a guide component, which is used to guide the air. A deodorizing bin 38 is fixedly connected to the lower right side of the inner wall of the outer shell 1, and a deodorizing liquid storage bin 39 is provided on the lower side of the inner part of the deodorizing bin 38. A one-way valve 40 is fixedly connected to the inner part of the deodorizing bin 38, and an activated carbon filter plate 41 is slidably connected to the middle part of the inner part of the deodorizing bin 38. A block 3 42 is provided on one side of the outer wall of the activated carbon filter plate 41; the guide component includes a guide plate 29, the outer wall of the guide plate 29 is fixedly connected to the inner wall of the outer shell 1, and a guide channel 26 is fixedly connected to the middle part of the inner wall of the outer shell 1, and one end of the guide channel 26 is fixedly connected to the inner bottom of the deodorizing bin 38; one end of the spring 35 is fixedly connected to the inside of the baffle 37, and the spring 35 is used to push one end of the slide rod 36 to move; a heat sink 43 is fixedly connected to the top of the outer shell 1, and the heat sink 43 is used to dissipate heat from the power supply 2.

[0041] Specifically, the filtered air is guided by the guide plate 29, and the purified air is guided into the guide channel 26, and the flow direction of the air is controlled by the one-way valve 40 arranged in the guide channel 26 to ensure that the air can only enter the deodorization chamber 38 in one direction. In the deodorization chamber 38, the air contacts the deodorizing liquid stored in the deodorizing liquid storage chamber 39. The deodorizing liquid reacts chemically with the odor molecules in the air by releasing chemical components, decomposes the odor into harmless substances, and significantly reduces the odor concentration in the air. This process can effectively remove common odor components such as hydrogen sulfide and ammonia, and provide fresher air for public sanitation spaces. The deodorized air is then further filtered through the activated carbon filter plate 41. The activated carbon filter plate 41 adopts a porous design and has extremely strong adsorption properties. It can adsorb residual odor molecules and harmful gases in the air to ensure that the air finally discharged is clean and odor-free.
