Description

Technical Field

[0001] This utility model belongs to the field of air deodorization and purification technology for toilets, and particularly relates to an air deodorization and purification device for high-speed rail toilets. Background Technology

[0002] High-speed rail has a large passenger flow and frequent use of restrooms. The enclosed and humid environment is prone to the growth of bacteria and viruses, and can also produce harmful gases such as hydrogen sulfide and ammonia, as well as various odors. These harmful gases and odors not only affect the passenger experience, but may also threaten the passenger's health. For example, the hydrogen sulfide poisoning incident in a public restroom in South Korea has sounded the alarm for public health and safety.

[0003] For example, Chinese Patent (Publication No.: CN219494321U) discloses an air deodorization and purification device for high-speed rail restrooms, effectively solving the problem of ammonia gas in restroom odors, which can easily harm external organisms if directly discharged. The device includes a main body with an air inlet pipe on the front and a connecting pipe on the top. An impurity filter assembly is installed inside the main body, and a deodorization assembly is installed on one side. The deodorization assembly includes an ammonia removal box installed on one side of the main body, with one end of the connecting pipe extending into the ammonia removal box. A bubble-breaking unit is installed inside the ammonia removal box, and a hanging rod is installed at the bottom. In this invention, a reverse current is applied to the fan motor, causing the fan blades to rotate. The device performs air backflushing, while the top rod continuously passes over the top block, causing the spring to vibrate. Under the combined action of backflushing and spring vibration, the dust on the filter plate is shaken off into the receiving cylinder, completing self-cleaning and facilitating subsequent use. However, in practical applications, the filter cleaning effect of this type of device still has significant limitations. The air in high-speed rail restrooms contains a high dust content and is mixed with impurities such as hair and fibers, making it difficult to thoroughly remove pollutants deeply attached to the filter. After long-term use, the filter is prone to clogging, leading to a decrease in air intake and a sharp reduction in purification efficiency. This not only affects the continuous operation of the device but also requires frequent manual intervention and maintenance, increasing operating costs and downtime. Therefore, an air deodorization and purification device for high-speed rail restrooms is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide an air deodorization and purification device for high-speed rail toilets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An air deodorization and purification device for high-speed rail toilets includes a dust collection box, a dust collection component connected inside the dust collection box, a waste bin connected to the bottom of the dust collection box, connecting blocks connected to both sides of the dust collection box, a partition rotatably connected between the two connecting blocks, and a coarse filter, a medium filter, a high efficiency filter and a flow guide hood arranged sequentially inside the dust collection box.

[0007] The dust removal assembly includes a fan, an air inlet pipe of the fan connected to a diversion pipe, a first sealing valve connected between the diversion pipe and the fan, a second sealing valve connected to the top of the diversion pipe, an air jet head connected to the top of the second sealing valve, an air compressor connected to the top of the air jet head, a connecting pipe connected to the air inlet pipe of the air compressor, and a connecting pipe connected to the air outlet of the fan.

[0008] In a further technical solution, the bottom end of the diverter is connected to the top end of the flow guide shroud, the flow guide shroud is inverted bucket shape, the mesh diameter of the coarse filter is larger than that of the medium filter, and the mesh diameter of the medium filter is larger than that of the high-efficiency filter.

[0009] A further technical solution is that the dust collector is internally connected to a limiting block, and there are two limiting blocks, one of which is located at the top of one side of the partition, and the other is located at the bottom of the other side of the partition.

[0010] In a further technical solution, a fixing bolt connects the dust collector and the waste bin, a discharge port is connected to one side of the waste bin, and a baffle is movably connected to the inner wall of the dust collector through a groove, the baffle being connected to the discharge port.

[0011] In a further technical solution, one end of the connecting pipe is connected to an ammonia removal device, the top of the ammonia removal device is connected to a connecting rod, the top of the connecting rod is connected to a deodorizing box, the top of the deodorizing box is connected to the connecting pipe, the deodorizing box and the ammonia removal device are connected by a connecting pipe, a waterproof and breathable membrane is connected between the connecting pipe and the bottom of the deodorizing box, and an activated carbon layer and a drying layer are sequentially arranged inside the deodorizing box.

[0012] In a further technical solution, an air inlet pipe is connected through one side of the dust collector, one end of the air inlet pipe is located above the partition, a differential pressure sensor is installed inside the dust collector, and an air storage tank is connected inside the air compressor.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, when the differential pressure sensor detects filter blockage, closes the first valve and opens the second valve. A high-pressure airflow is provided by an air compressor and precisely sprayed onto the filter surface via a jet nozzle, effectively removing dust, fibers, and other impurities deeply attached to the filter. Simultaneously, the waste generated during cleaning is guided by a partition into a waste bin. The waste bin and outlet design facilitate centralized processing, reducing the frequency of manual intervention and lowering operation and maintenance costs. Through the inclusion of coarse, medium, and high-efficiency filters, a multi-level filtration system is formed, specifically intercepting pollutants of different particle sizes. The coarse filter blocks large dust particles and hair impurities, the medium filter filters fine dust and some microorganisms, and the high-efficiency filter further purifies tiny particles. Combined with an inverted bucket-shaped airflow guide, the airflow distribution is optimized to ensure the cleanliness of the air entering subsequent purification stages.

[0015] This utility model features a rotating connection structure between the dust collection box, connecting block, and partition, allowing for flexible adjustment of the internal space layout to suit the confined installation environment of high-speed rail restrooms. The limiting block's fixing effect on the partition and the fixed bolt connection to the waste bin enhance the structural stability of the device under train vibration. This ensures that the partition remains flat during air purification, preventing air from being stirred up inside the waste bin and affecting the dust collection effect. When the device needs cleaning, the high-pressure air jet can rotate the partition, opening the waste bin and allowing the waste on the filter screen to fall precisely into the waste bin, facilitating user operation.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] like Figures 1-5 As shown, this utility model embodiment provides an air deodorization and purification device for high-speed rail toilets, including a dust collection box 1, a dust collection component 2 connected inside the dust collection box 1, a waste box 3 connected to the bottom of the dust collection box 1, connecting blocks 4 connected to both sides of the dust collection box 1, a partition 5 rotatably connected between the two connecting blocks 4, and a coarse filter 6, a medium filter 7, a high efficiency filter 8 and a flow guide hood 9 arranged sequentially inside the dust collection box 1;

[0026] The dust removal assembly 2 includes a fan 201, an air inlet pipe of the fan 201 connected to a diversion pipe 202, a first sealing valve 203 connected between the diversion pipe 202 and the fan 201, a second sealing valve 204 connected to the top of the diversion pipe 202, a jet nozzle 205 connected to the top of the second sealing valve 204, an air compressor 206 connected to the top of the jet nozzle 205, a connecting pipe 207 connected to the air inlet pipe of the air compressor 206, and a connecting pipe 208 connected to the air outlet of the fan 201.

[0027] In this embodiment, when air purification is required, the second valve 204 is closed, the first valve 203 is opened, and the fan 201 is started. This allows the odor from the bathroom to be drawn into the dust collection box 1 through the air intake pipe 10. A multi-level filtration system is formed by the coarse filter 6, medium-efficiency filter 7, and high-efficiency filter 8, which can specifically intercept pollutants of different particle sizes. The coarse filter 6 blocks large dust particles and hair impurities, the medium-efficiency filter 7 filters fine dust and some microorganisms, and the high-efficiency filter 8 further purifies fine particulate matter. Combined with the inverted bucket-shaped air guide hood 9 to optimize airflow distribution, the cleanliness of the air entering subsequent purification stages is ensured. The air then enters the ammonia removal device 14 through the connecting pipe 208 to remove ammonia from the air. The air then enters the deodorization box 11 through the pipe, where it passes through the drying layer 13 and the activated carbon layer 12 to remove moisture and odors. The air compressor 206 is then started, compressing the purified air into the air storage box for storage. When the differential pressure sensor detects that the filter screen is clogged, the first valve 203 is closed and the second valve 204 is opened. The high-pressure airflow provided by the air compressor 206 is then precisely sprayed onto the filter screen surface through the jet nozzle 205, effectively removing dust, fibers, and other impurities that are deeply attached to the filter screen.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, the bottom end of the diversion pipe 202 is connected to the top end of the flow guide shroud 9. The flow guide shroud 9 is inverted bucket shape. The mesh size of the coarse filter 6 is larger than that of the medium filter 7, and the mesh size of the medium filter 7 is larger than that of the high efficiency filter 8.

[0029] The dust collector 1 is internally connected to a limiting block 16. There are two limiting blocks 16, one of which is located at the top of one side of the partition 5, and the other is located at the bottom of the other side of the partition 5.

[0030] A fixing bolt 19 is connected between the dust collection box 1 and the waste box 3. A discharge port 18 is connected to one side of the waste box 3. A baffle 17 is movably connected to the inner wall of the dust collection box 1 through a groove. The baffle 17 is connected to the discharge port 18.

[0031] One end of the connecting pipe 208 is connected to an ammonia removal device 14. The top of the ammonia removal device 14 is connected to a connecting rod 15. The top of the connecting rod 15 is connected to a deodorizing box 11. The top of the deodorizing box 11 is connected to the connecting pipe 207. The deodorizing box 11 and the ammonia removal device 14 are connected by a connecting pipe. A waterproof and breathable membrane 20 is connected between the connecting pipe and the bottom of the deodorizing box 11. An activated carbon layer 12 and a drying layer 13 are arranged sequentially inside the deodorizing box 11.

[0032] An air inlet pipe 10 is connected through one side of the dust collector 1. One end of the air inlet pipe 10 is located above the partition 5. A differential pressure sensor is installed inside the dust collector 1. An air storage box is connected inside the air compressor 206.

[0033] In this embodiment, the rotating connection structure between the dust collector 1, the connecting block 4, and the partition 5 allows for flexible adjustment of the internal space layout. The fixing effect of the limiting block 16 on the partition 5 and the connection of the waste bin 3 with the fixing bolts 19 enhance the structural stability of the device under train vibration. This ensures that the partition 5 remains in a flat state when the equipment is purifying air, preventing air from being stirred up inside the waste bin 3 and affecting the dust removal effect of the equipment. When the equipment needs to be cleaned, the high-pressure air blown out can drive the partition 5 to rotate, opening the waste bin 3 and allowing the waste on the filter screen to fall accurately into the waste bin 3, making it convenient for users.

[0034] The working principle of this utility model is as follows: First, when air purification is required, the second valve 204 is closed, the first valve 203 is opened, and the fan 201 is started. The odor from the bathroom is then drawn into the dust collection box 1 through the air inlet pipe 10. A multi-level filtration system is formed by the coarse filter 6, medium-efficiency filter 7, and high-efficiency filter 8, which can specifically intercept pollutants of different particle sizes. Combined with the inverted bucket-shaped air guide hood 9 to optimize airflow distribution, the cleanliness of the air entering subsequent purification stages is ensured. Then, the air enters the ammonia removal device 14 through the connecting pipe 208 to remove... Ammonia in the air is removed, and the air then enters the deodorization box 11 through a pipe. The drying layer 13 and activated carbon layer 12 remove moisture and odors from the air. The air compressor 206 is then started, and the purified air is compressed into the air storage box for storage. Finally, when the differential pressure sensor detects that the filter is clogged, the first valve 203 is closed and the second valve 204 is opened. The high-pressure airflow provided by the air compressor 206 is precisely sprayed onto the filter surface through the jet nozzle 205, which can effectively remove dust, fibers and other impurities that are deeply attached to the filter.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
