Description

Technical Field

[0001] The invention relates to the field of odor filtering, and in particular to a mobile odor purification device for a laboratory animal room. Background Art

[0002] The reasons why odor purification devices need to be installed in animal laboratories can be analyzed from multiple dimensions, including odor sources, health hazards, experimental interference, compliance requirements, and comprehensive solutions. Specifically, they are as follows: 1. The sources of odors are complex and highly harmful. The animal's own secretions (such as sweat and dandruff) and chemical reagents used in the laboratory (such as formaldehyde and ethylene oxide) will also release volatile organic compounds (VOCs) and irritating odors that will affect experimental data and the animals themselves.

[0003] In contrast, the Chinese invention with publication number CN112728709A discloses a multifunctional air purification and disinfection machine. This scheme adopts G4 and F8 filter screens, activated carbon adsorption devices, contact and photocatalyst decomposition plates and other technologies, combined with ultraviolet irradiation of specific wavelengths, to achieve multi-level air purification and disinfection. Animal laboratories usually use such equipment to treat and purify odors in the laboratory. However, in the practical application of such schemes and equipment, the following problems still exist: 1. Because different animals in animal laboratories have different habits, the surrounding environment also has different effects on them, so it is usually necessary to ensure as few noise sources as possible; 2. Although conventional air purification equipment can effectively deal with hair and odor, due to environmental reasons, hair may block the air inlet, causing filtration failure, so it is often necessary to clean the air purification equipment in the near future; 3. Based on economic considerations, granular filter materials are generally used. During use, granular filter materials absorb odors through the exposed parts. When the particles are stored in the container, the stacking surfaces between the particles do not participate in the air purification. The effectiveness of the granular filter materials also needs to be ensured. Summary of the invention

[0004] The present invention provides a mobile odor purification device for a laboratory animal room, so as to solve the technical problem that in the existing odor treatment equipment, the air intake speed is reduced for the sake of silence, but the animal hair blocks the air intake, resulting in the power part being unable to effectively treat the odor in a timely manner.

[0021] An embodiment of a mobile odor purification device for a laboratory animal room of the present invention is as follows Figures 1 to 14 As shown, it includes a frame 1 for installation and movement, an inner filter mechanism 2 for providing bass effect, a cleaning mechanism 4 for processing hair and odor, and a top filter mechanism 3.

[0023] Furthermore, the switching mechanism 5 includes a driving gear 51, which is fixedly connected to the main shaft 25. A clamping block 52 is arranged on the upper side of the driving gear 51.

The limiting ring 53 is provided with an opening passing through the clamping block 52. A transmission assembly 54 matching the driving gear 51 is arranged on the lower side of the limiting ring 53. The input end of the transmission assembly 54 cooperates with the driving gear 51, and the output end of the transmission assembly 54 cooperates with the passive gear ring 55 on the cleaning ring 41.

[0024] Furthermore, the cleaning mechanism 4 also includes a hair filter 42, and the cleaning ring 41 is divided into a ventilation area and a cleaning area. The hair filter 42 is embedded and connected to the air inlet position of the base 21, and the cleaning ring 41 is wrapped around the outside of the hair filter 42. A shaving device is provided on the inner wall of the cleaning area of ​​the cleaning ring 41 corresponding to the hair filter 42, and a storage box for storing shaved hair is provided on the lower side of the cleaning ring 41 of the base 21.

[0025] Furthermore, the cleaning ring 41 is provided with four ventilation areas and four cleaning areas, and the ventilation areas and the cleaning areas are arranged alternately, and the storage box is located at the lower side of the initial position of the cleaning area.

[0026] Furthermore, the top filtering mechanism 3 includes a filter material storage barrel 31, which is a cylindrical structure surrounded by a filter screen. A bottom air inlet plate 32 is provided at the bottom of the filter material storage barrel 31 corresponding to the position of the main shaft 25, and a rotating shaft 34 is penetrated through the bottom air inlet plate 32. A toggle plate 33 is provided inside the filter material storage barrel 31 and located on the rotating shaft 34. A plurality of toggle rods are evenly provided on the outer circumferential surface of the toggle plate 33, and the toggle mechanism 7 is installed between the bottom of the rotating shaft 34 and the top of the main shaft 25.

[0027] Furthermore, the toggle mechanism 7 includes a mating block 73, four mating blocks 73 are arranged in a circular array on the rotating shaft 34, a groove for mating with the rotating shaft 34 is formed on the main shaft 25, an idle groove 71 is arranged at the bottom position of the groove, the idle groove 71 does not contact the mating block 73, and a mating groove 72 for mating with the mating block 73 is formed on the upper side of the idle groove 71. When the main shaft 25 sinks, the mating groove 72 will cooperate with the mating groove 72, so that the main shaft 25 drives the rotating shaft 34 to rotate.

[0028] Furthermore, the ratio of the size of the bottom air inlet of the cone 26 to the size of the top air outlet is 2:1.

[0029] Furthermore, the power assembly 6 is a stepping motor.

[0030] Furthermore, the bottom air inlet plate 32 is a conical air permeable plate.

[0031] Furthermore, universal wheels are provided at the bottom of the frame 1, and a sterilization lamp is provided at the air outlet position at the top of the frame 1.

[0032] The working principle is as follows: according to the needs, the use environment of the equipment is adjusted. When it is needed to be used in the laboratory, the power of the stepper motor is controlled so that the stepper motor drives the main shaft 25 to rotate. At this time, the spiral extrusion blades 23 and the conical extrusion blades 24 are driven to rotate slowly. The air is introduced in a spiral extrusion manner. The frequency of the sound-generating part of the equipment is relatively small, thereby reducing the noise as much as possible to avoid affecting the animals in the laboratory. Because the air inlet of the device is at the bottom and the air outlet is at the top, it is easier to suck the odor into the device because the specific gravity of the odor is greater than that of the air. At the same time, because the hair is also accumulated on the ground, it is also easy to suck the hair in. When the hair accumulates on the surface of the hair filter 42 to a certain amount, the air intake of the base 21 is small, and the spiral extrusion blades 23 continue to rotate. Because the spiral extrusion blades 23 cannot draw in more air, a negative pressure is formed between the bottom of the spiral extrusion blades 23 and the base 21. At this time, the high air pressure at the top will force the spiral extrusion blades 23 to sink. When the spiral extrusion blades 23 sink, the spiral extrusion blades 23 and the main shaft 25 sink synchronously, and the block 52 at the bottom of the main shaft 25 will first abut against the upper surface of the limit ring 53. When the main shaft 25 drives the block 52 to continue rotating, the block 52 will sink to the bottom of the limit ring 53 through the opening of the limit ring 53 (such as Figure 12-13 ), when the block 52 and the main shaft 25 sink, the driving gear 51 will contact the gear of the transmission assembly 54, and after the transmission is transmitted through the gear and sprocket of the transmission assembly 54 (such as Fig.10As shown in the figure, the gear at the output position of the transmission assembly 54 will cooperate with the passive gear ring 55, thereby driving the passive gear ring 55 and the transmission assembly 54 to rotate. When the transmission assembly 54 rotates, the internal scraper will scrape off the hair on the surface of the hair filter 42. When the cleaning ring 41 rotates 45 degrees, the hair will lose suction and fall into the storage box at the bottom; When the main shaft 25 sinks synchronously, the matching groove 72 on the main shaft 25 will match with the matching block 73 on the rotating shaft 34, and the matching block 73, the rotating shaft 34 and the dial 33 will be passively driven to rotate, and the dial 33 will cause the particle filter material to roll, so that the part of the filter material that was originally exposed and full of odor particles will roll, and the original overlapping part of the filter material will leak out, so as to better absorb the odor; When the hair is removed, the main shaft 25 is supported by the bottom return spring, and the block 52 runs out of the cutout of the limit ring 53, so that the main shaft 25 is reset, and the spiral extrusion blades 23 and the conical extrusion blades 24 continue to filter the air.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
