Description

Technical Field

[0001] This utility model belongs to the technical field of trash can equipment, specifically relating to a negative pressure desktop trash can for cell culture. Background Technology

[0002] Cell culture is a crucial step in biomedical research and the biotechnology industry. However, the cell culture process generates a large amount of waste, which, if not handled properly, can easily pollute the cell culture environment, thereby affecting the accuracy and reproducibility of experimental results.

[0003] Traditional methods of disposing of cell culture waste often involve using ordinary trash cans, which can easily lead to the diffusion of harmful substances from the waste into the outside air, increasing the risk of pollution and affecting laboratory personnel.

[0004] Therefore, there is an urgent need for a treatment device that can reduce the risk of contamination in order to ensure the cleanliness and safety of the cell culture process. Utility Model Content

[0005] The purpose of this invention is to solve the aforementioned technical problems in the prior art and to provide a negative pressure desktop trash can for cell culture. By setting a support at the bottom of the trash can body, the trash can body can be placed on a desktop for easy dumping of waste by experimental personnel. An opening for dumping waste is opened at the top of the trash can body. A negative pressure circulation component is set in the trash can body so that the gas generated by waste can circulate inside the trash can body, preventing the gas from spreading to the outside and affecting the operation of experimental personnel, reducing the risk of contamination and improving safety.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A negative pressure desktop trash can for cell culture includes a trash can body with an opening at the top and a support at the bottom for support on a desktop. A negative pressure circulation component is installed inside the trash can body to control the circulation of gas within the body. This invention facilitates the disposal of waste by providing a support at the bottom of the trash can body for easy placement on a desktop. The opening at the top allows for waste disposal, and the negative pressure circulation component ensures that gases generated during waste disposal circulate within the trash can body, preventing gas from spreading to the outside and affecting operator work, thus reducing the risk of contamination and improving safety.

[0008] Furthermore, the trash can body includes an outer shell and an inner barrel. An air duct for gas circulation is formed between the side walls of the outer shell and the inner barrel. A purification component is installed within the air duct. The air duct is connected to the interior of the trash can body. The top of the inner barrel is lower than the top of the outer shell, making the top surface of the air duct sloped. Air outlets are evenly distributed on this sloped surface. This sloped surface causes the gas discharged from the air duct to converge towards the center of the opening in the trash can body, facilitating the re-absorption of the gas by the negative pressure circulation component. This achieves gas circulation within the trash can, preventing it from diffusing to the outside. The sloped surface improves the smoothness of gas circulation, and the purification component purifies the gas entering the air duct, reducing or eliminating safety hazards.

[0009] Furthermore, the purification components include a pre-filter and an activated carbon filter, both fixedly connected within the air duct, with the activated carbon filter positioned above the pre-filter. The negative pressure circulation assembly draws gas into the bottom of the trash can body through the opening, where it then enters the air duct. The gas is then transported upwards from the bottom of the duct, undergoing preliminary filtration by the pre-filter, which primarily filters large particles of dust, hair, cardboard scraps, and lint. This pre-filtration by the pre-filter blocks large particles, reducing the pressure on subsequent filters. The pre-filtered gas then undergoes secondary filtration by the activated carbon filter. Utilizing the pores and large surface area of ​​the activated carbon, it effectively filters out odors and harmful gases from the air, purifying the air and reducing or eliminating safety hazards.

[0010] Furthermore, an installation cavity is formed between the bottom of the inner bin and the bottom of the outer bin, and the installation cavity is connected to the air duct. The negative pressure circulation component is located inside the installation cavity. The installation cavity is designed for the installation of the negative pressure circulation component. At the same time, gas is drawn downward from the opening of the trash can body into the installation cavity, and then enters the air duct from the outer circumference of the installation cavity. The gas discharged from the outlet of the air duct is adsorbed by the negative pressure circulation component and re-enters the trash can body, realizing the circulation of gas within the trash can body.

[0011] Furthermore, a waste liquid screen is installed at the bottom of the inner tank, with evenly distributed screen holes. The waste liquid screen enables solid-liquid separation of waste, so that solid impurities remain on the waste liquid screen, while waste liquid enters the installation cavity through the screen holes.

[0012] Furthermore, the negative pressure circulation component includes an impeller, a motor, and a mounting base. The impeller is rotatably connected to the mounting cavity. The bottom of the trash can body is provided with a mounting base, and the motor is fixedly connected to the mounting base. A truncated cone protrudes upward from the mounting base in the mounting cavity. The output shaft of the motor is connected to the trash can body through a shaft seal. The output shaft of the motor passes through the truncated cone and connects to the impeller. The motor controls the rotation of the impeller, so that the gas circulates between the inside of the trash can body and the air duct. The motor is mounted on a mounting base at the bottom of the trash can body. The motor output shaft passes through the trash can body and the truncated cone and connects to the impeller. The truncated cone design ensures that the waste after passing through the waste liquid screen is between the bottom of the truncated cone and the inner wall of the outer shell, preventing waste liquid leakage. The motor output shaft is connected to the bottom of the trash can body through a shaft seal, ensuring the sealing of the bottom of the trash can body and preventing waste liquid leakage. The motor controls the impeller to rotate, causing gas to enter the trash can body through the opening and then into the mounting cavity. The gas in the mounting cavity diffuses into the air duct, is purified by the purification components in the air duct, and is discharged from the air outlet. The discharged gas is then reabsorbed into the mounting cavity by the negative pressure circulation component, realizing gas circulation and thus preventing gas diffusion.

[0013] Furthermore, the bottom of the trash can body is equipped with a waste liquid outlet, which is connected to the mounting cavity and has a discharge pipe. Waste liquid in the mounting cavity can be discharged from the discharge pipe.

[0014] Furthermore, the support frame includes a base plate, a limiting ring, and a support platform. Both the limiting ring and the support platform are fixedly connected to the base plate. The support platform is located below the limiting ring and rests against the bottom of the trash can body. The limiting ring is locked and secured to the outer wall of the trash can body. By placing the bottom of the trash can body through the limiting ring onto the support platform, the limiting ring limits the movement of the trash can body, and the support platform supports the trash can body.

[0015] Furthermore, connecting portions are provided on both sides of the limiting ring. The bottom of the connecting portions is fixedly connected to the base plate. The diameter of the trash can body gradually decreases from top to bottom. The limiting ring is fitted onto the outside of the trash can body. The diameter of the limiting ring is smaller than the diameter of the top of the trash can body and larger than the diameter of the bottom of the trash can body. The connecting portions are used to support and fix the limiting ring on the base plate. The setting of the limiting ring diameter ensures that the limiting ring fits onto the outside of the trash can body, thereby limiting the position of the trash can body and increasing the stability of the trash can body when placed.

[0016] Furthermore, support columns are distributed around the bottom circumference of the support platform. The bottom of each support column is fixedly connected to the base plate, with gaps between adjacent support columns. A through hole runs through the center of the support platform. The support columns are used to fix the support platform to the base plate. The gaps facilitate heat dissipation for the motor, and the through hole facilitates motor installation.

[0017] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0018] This invention features a support at the bottom of the trash can body, allowing it to be placed on a table for easy disposal of waste by laboratory personnel. An opening for emptying waste is located at the top of the trash can body. A negative pressure circulation component is installed inside the trash can body, enabling the gas generated by waste to circulate within the body, preventing gas from spreading to the outside and affecting laboratory operations, thus reducing the risk of contamination and improving safety.

[0019] In this invention, the impeller, driven by a motor, creates a negative pressure environment, drawing gas from the opening into the trash can body. The gas then passes through a waste liquid screen and an installation cavity, radially into the air duct. After passing through a primary filter and an activated carbon filter for secondary filtration, the gas is discharged from the outlet. Guided by the inclined surface and the negative pressure environment, the discharged gas re-enters the trash can body, achieving gas circulation within the trash can. This prevents the gas inside the trash can from spreading to the outside, reducing or eliminating safety hazards. Attached Figure Description

[0029] The trash can body 1 includes an outer shell 5 and an inner barrel 6. An air duct 7 for gas circulation is formed between the side walls of the outer shell 5 and the inner barrel 6. A purification component is installed within the air duct 7. The air duct 7 is connected to the interior of the trash can body 1. The top of the inner barrel 6 is lower than the top of the outer shell 5, making the top surface of the air duct 7 inclined (8). Air outlets 9 are evenly distributed on the inclined surface 8. The inclined surface 8 causes the gas discharged from the air duct 7 to converge towards the center of the opening 2 of the trash can body 1, facilitating the re-absorption of the negative pressure circulation component 4 into the trash can body 1. This achieves gas circulation within the trash can, preventing it from diffusing to the outside. The inclined surface 8 improves the smoothness of gas circulation, and the purification component purifies the gas entering the air duct 7, reducing or eliminating safety hazards.

[0030] The purification components include a pre-filter 10 and an activated carbon filter 11, both of which are fixedly connected within the air duct 7, with the activated carbon filter 11 positioned above the pre-filter 10. The negative pressure circulation assembly 4 draws gas from the opening 2 into the bottom of the trash can body 1, where it then enters the air duct 7. The gas is then transported upwards from the bottom of the air duct 7, undergoing preliminary filtration by the pre-filter 10. The pre-filter 10 primarily filters large particles of dust, hair, paper scraps, and lint. This pre-filtration by the pre-filter 10 blocks large particles, reducing the pressure on subsequent filters. The pre-filtered gas then undergoes secondary filtration by the activated carbon filter 11. Utilizing the porosity and large surface area of ​​the activated carbon, it effectively filters out odors and harmful gases from the air, purifying the gas and reducing or eliminating safety hazards.

[0031] An installation cavity 12 is formed between the bottom of the inner bin 6 and the bottom of the outer shell 5. The installation cavity 12 is connected to the air duct 7, and the negative pressure circulation component 4 is located inside the installation cavity 12. The installation cavity 12 is provided for the installation of the negative pressure circulation component 4. At the same time, gas is drawn downward from the opening 2 of the trash can body 1 into the installation cavity 12, and then enters the air duct 7 from the outer circumference of the installation cavity 12. The gas discharged from the outlet of the air duct 7 is adsorbed by the negative pressure circulation component 4 and re-enters the trash can body 1, realizing the circulation of gas within the trash can body 1.

[0032] The bottom of the inner tank 6 is equipped with a waste liquid screen 13, which has screen holes 14 evenly distributed. The waste liquid screen 13 enables solid-liquid separation of waste, so that solid impurities are located on the waste liquid screen 13, and waste liquid enters the installation cavity 12 through the screen holes 14.

[0033] The negative pressure circulation assembly 4 includes an impeller 15, a motor 16, and a mounting base 17. The impeller 15 is rotatably connected in the mounting cavity 12. The bottom of the trash can body 1 is provided with the mounting base 17. The motor 16 is fixedly connected to the mounting base 17. A truncated cone 18 is formed in the mounting cavity 12 corresponding to the mounting base 17. The output shaft 27 of the motor 16 is connected to the trash can body 1 through the shaft seal 28. The output shaft 27 of the motor 16 passes through the truncated cone 18 and is connected to the impeller 15. The motor 16 controls the impeller 15 to rotate, so that the gas circulates between the inside of the trash can body 1 and the air duct 7. The motor 16 is mounted on the mounting base 17 at the bottom of the trash can body 1. The output shaft 27 of the motor 16 passes through the trash can body 1 and the truncated cone 18 and is connected to the impeller 15. The truncated cone 18 is designed so that the waste after passing through the waste liquid screen 13 is between the bottom of the truncated cone 18 and the inner wall of the outer shell 5, thus preventing waste liquid leakage. The output shaft 27 of the motor 16 is connected to the bottom of the trash can body 1 by a shaft seal 28, which ensures the sealing of the bottom of the trash can body 1 and prevents waste liquid leakage. The motor 16 controls the impeller 15 to rotate, so that the gas enters the trash can body through the opening and then enters the mounting cavity 12. The gas in the mounting cavity 12 diffuses into the air duct, is purified by the purification components in the air duct, and is discharged from the air outlet 9. The discharged gas is reabsorbed into the mounting cavity by the negative pressure circulation component to complete the circulation, thereby preventing the gas from diffusing.

[0034] The bottom of the trash can body 1 is provided with a waste liquid outlet 19, which is connected to the mounting cavity 12 and is connected to a liquid outlet pipe 20. Waste liquid in the mounting cavity 12 can be discharged from the liquid outlet pipe 20.

The diameter of the limiting ring 22 is smaller than the diameter of the top of the trash can body 1 and larger than the diameter of the bottom of the trash can body 1. The connecting portions 24 are used to support and fix the limiting ring 22 on the base plate 21. The diameter of the limiting ring 22 is set so that it fits onto the outside of the trash can body 1, thereby limiting the trash can body 1 and increasing the stability of the trash can body 1.

[0037] Support columns 25 are distributed around the bottom circumference of the support platform 23.
