Description

Technical Field

[0001] This invention belongs to the field of microbial culture equipment technology, specifically relating to a medical testing microbial culture device that is easy to clean and maintain. Background Technology

[0002] Microbial culture refers to the process of rapidly growing and multiplying certain microorganisms using artificially prepared culture media and artificially created culture conditions, such as culture temperature. Microbial culture can be divided into pure culture and mixed culture. The former refers to the cultivation and utilization of purified single strains; the latter refers to the cultivation of microorganisms from mixed strains or natural samples. Based on the types and quantities of microorganisms growing on the culture medium, the diversity and quantity of microorganisms in the soil can be estimated to a certain extent.

[0003] In medical testing, petri dishes are often used to culture microorganisms. A petri dish is a laboratory vessel used for culturing microorganisms or cells. It consists of a flat, disc-shaped base and a lid, and is usually made of glass or plastic.

[0004] However, when using petri dishes to culture microorganisms, simple cleaning and maintenance cannot be performed in the early or late stages of cultivation, which affects the applicability of the petri dishes and limits the types of microorganisms that can be cultured.

[0005] Based on this, a medical testing microbial culture device that is easy to clean and maintain is proposed. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following advantages: 1. This invention features a culture base within a culture tank. The culture base is a circular seat with a concave cavity, used for the cultivation of bent microorganisms. Drive mechanisms are located on both sides of the culture tank along the same diameter line, with a cleaning and maintenance mechanism installed between them. Each drive mechanism includes a lifting cylinder, a connecting rod, a rotating motor, and a connecting block. The lifting cylinder is fixed to the side wall of the culture tank, and a connecting rod is fixed to the top of its telescopic shaft. The connecting rod is L-shaped, with its other end facing away from the inner cavity of the culture tank. A rotating motor is fixed to the other end of the connecting rod, and a connecting block is fixed to the rotating shaft of the rotating motor. The mounting ends of the cleaning and maintenance cylinder and the cleaning and maintenance rod are respectively fixed to the connecting blocks of the corresponding drive mechanisms. The lifting cylinder adjusts the downward pressure or upward range, facilitating the adjustment of the cleaning and scraping force on the surface of the culture base under different conditions.

[0019] 3. In this invention, a partition groove is provided between the culture base and the side wall of the culture tank. The rotating motor is located in the partition groove, and the outer periphery of the rotating motor does not contact the partition groove, so that the rotating motor can dissipate heat in time and avoid the rotating shaft of the rotating motor from being affected by external obstacles and thus affecting its free rotation.

[0020] 4. In this invention, a waste discharge port is provided at the bottom of the partitioned tank in the culture tank. A sealing plate is snapped onto the outside of the waste discharge port. The sealing plate can complete the sealing operation in the culture tank during anaerobic culture, which facilitates the cleaning of impurities in the culture tank.

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figure 1-4 As shown, the present invention provides a technical solution: a medical testing microbial culture device that is easy to clean and maintain, including a culture tank 1, wherein a cover plate 2 is snapped onto the top opening of the culture tank 1, and the cover plate 2 and the culture tank 1 are used in conjunction.

[0026] The culture tank 1 is provided with a culture seat 3, which is a circular seat with a concave cavity. The concave cavity of the culture seat 3 is used for the cultivation of bent microorganisms.

[0027] The culture tank 1 is provided with a drive mechanism 4 on both sides of the same diameter line, and a cleaning and maintenance mechanism 5 is installed between the two drive mechanisms 4. The drive mechanism 4 includes a lifting cylinder 41, a connecting rod 42, a rotating motor 43, and a connecting block 44. The lifting cylinder 41 is fixed inside the side wall of the culture tank 1, and a connecting rod 42 is fixed at the top of the telescopic shaft of the lifting cylinder 41. The connecting rod 42 is an L-shaped rod, and the other end of the connecting rod 42 faces the inner cavity of the culture tank 1. A rotating motor 43 is fixed at the other end of the connecting rod 42, and a connecting block 44 is fixed on the rotating shaft of the rotating motor 43. The mounting ends of the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52 are respectively fixed on the connecting blocks 44 of the corresponding drive mechanism 4. The lifting cylinder 41 can adjust the downward pressure or the upward range, which facilitates the adjustment of the cleaning and scraping force on the surface of the culture tank 3 under different conditions.

[0028] The rotation angle of the rotating shaft of the rotating motor 43 is no more than 180°. The rotating motor 43 can drive the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52 to move on the surface of the culture base 3 to achieve the scraping, cleaning and maintenance operation.

[0029] The cleaning and maintenance mechanism 5 includes a cleaning and maintenance cylinder 51 and a cleaning and maintenance rod 52. One end of the cleaning and maintenance cylinder 51 is fixed to one of the driving mechanisms 4, and the cleaning and maintenance cylinder 51 is specifically a hollow cylinder structure with an inverted U-shaped cross-section and an open bottom. The cleaning and maintenance rod 52 is sleeved inside the cleaning and maintenance cylinder 51, and the outer end of the cleaning and maintenance rod 52 is fixed to another driving mechanism 4. Under the action of the two driving mechanisms 4, the cleaning and maintenance mechanism 5 is driven to perform cleaning and maintenance operations on the surface of the culture base 3. When the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52 rotate to scrape and clean, the length of the sleeve between the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52 can be automatically adjusted by changing the rotation angle, so as to adapt to the scraping and cleaning operation of the circular surface of the culture base 3.

[0030] The bottom end of the cleaning and maintenance cylinder 51 is symmetrically provided with two first bristles 53, and the bottom end of the cleaning and maintenance rod 52 is provided with a second bristle 54. The first bristles 53 and the second bristles 54 work together to complete the cleaning and maintenance of the culture base 3.

[0031] To improve cleaning efficiency and quality, the bristles of the first bristle 53 and the second bristle 54 are arranged at an angle, and the angles of the first bristle 53 and the second bristle 54 are symmetrical to each other.

[0032] To facilitate adaptation to the circular structure of the culture base 3 surface, both the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52 are made of flexible plastic, and the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52 are naturally concave circular in shape.

[0033] The sidewall of the culture tank 1 is an inwardly inclined surface, and the distance between the transverse section of the connecting rod 42 and the inclined surface of the culture tank 1 is not less than 5mm, which facilitates connection with the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52, and also facilitates the adjustment of the downward pressure of the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52 during use.

[0034] A partition groove 6 is provided between the culture base 3 and the side wall of the culture tank 1. The rotating motor 43 is located in the partition groove 6, and the outer periphery of the rotating motor 43 does not contact the partition groove 6, so that the rotating motor 43 can dissipate heat in time and avoid the rotating shaft of the rotating motor 43 from being affected by external obstacles and thus preventing it from rotating freely.

[0035] To facilitate the cleaning of impurities inside the culture tank 1, a discharge port 61 is provided at the bottom of the partition groove 6 inside the culture tank 1. A sealing plate is snapped onto the outside of the discharge port 61, and the sealing plate can complete the sealing operation inside the culture tank 1 during anaerobic culture.

[0036] The cleaning and maintenance rod 52 has a hollow cavity inside, and multiple cleaning water connection holes are provided on both the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52. During use, the cleaning water connection holes are used to connect to an external cleaning water tank through the water pipe and water pump, so that external water can be used for cleaning operations during the use of the cleaning and maintenance cylinder 51 and the cleaning and maintenance rod 52.
