Description

Technical Field

[0001] This utility model relates to the field of incubator technology, and in particular to a microbial testing incubator that is easy to handle. Background Technology

[0002] Microbial incubators provide a stable and suitable growth environment for microorganisms, ensuring that they can reproduce and be cultured under controlled conditions of temperature, humidity, and gas composition, thereby meeting various experimental and production needs.

[0003] Traditional microbial incubators typically employ a relatively simple cabinet structure design, which presents several significant inconveniences in practical use. For example, the shelves inside the incubator are often fixed, requiring researchers to stretch their arms considerably, sometimes even needing tools, to reach culture containers located deep inside or at higher positions. This is not only cumbersome and inefficient but also prone to cross-contamination due to accidental contact with other cultured samples, affecting the accuracy and reliability of experimental results.

[0004] Chinese utility model patent CN211972311U discloses a microbial incubator for bioengineering, comprising an incubator shell. Five sets of partitions are equidistantly arranged along the vertical direction within the incubator shell, dividing the shell into five incubation chambers. Each incubation chamber has a fixed placement seat with a slot at its top. A culture dish is placed in the slot, and a clamping block is fixedly installed within the chamber. An adsorption block is movably mounted on the clamping block, and a top block is fixedly installed at the top of the chamber. The top of the inner wall of a spring groove is fixedly connected to one end of a spring. This microbial incubator for bioengineering divides the shell into five incubation chambers using five sets of partitions. The placement seat and slot within each chamber are for storing culture dishes. The clamping block and adsorption block are for holding labels, facilitating the differentiation of culture dishes. The spring and pressure block are for holding the culture dishes and recording documents. This microbial incubator for bioengineering is easy to use and highly functional.

[0005] In this design, the height of each culture chamber is constant. However, in actual culture experiments, a single incubator may contain multiple culture samples, each held in different containers such as conical flasks and petri dishes, resulting in variations in height. The existing incubators have a constant chamber height, and the space required to retrieve taller containers like conical flasks differs from that required to retrieve petri dishes. If all containers are designed with a higher height, space utilization is generally low. The current design lacks comprehensive consideration and fails to fundamentally address the problems encountered by researchers during retrieval. Utility Model Content

[0006] To address the shortcomings of the aforementioned background technology, this utility model proposes a convenient microbial testing incubator, which solves the problem that the internal layer height of the incubator cannot be adaptively adjusted in the prior art.

Detailed Implementation

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

[0025] like Figure 1 As shown in Embodiment 1, a convenient microbial testing incubator includes a housing 1, which provides installation space for the entire internal structure of the incubator. The housing 1 contains several layers of trays 2, which are slidably connected to the housing 1. A vertical drive mechanism 3 is provided between the trays 2 and the housing 1, driving the trays to move vertically along the housing, changing their positions and thus altering the layer height to accommodate culture containers of different heights. The vertical drive mechanism 3 also allows the trays 2 to slide vertically on the housing 1. A sliding conductive structure 4 is provided between the trays 2 and the housing 1, supplying power to the electrical components on each tray before and after movement. A tray 5 slides on the tray 2, and the tray 5 has several placement positions 6, each with an elastic locking structure 7. In this embodiment, by sliding the tray onto the bracket, the tray can be pulled outward from the bracket when the culture container needs to be retrieved, improving ease of retrieval. The elastic locking structure clamps and secures the culture container placed in its position, maintaining its stability. This incubator has a reliable structure, high space utilization, and allows for adaptive adjustment of the shelf height according to actual needs. It also facilitates the retrieval of culture containers, making it convenient to use.

[0026] Example 2: A convenient microbial testing incubator, based on Example 1, such as... Figure 2 As shown, the bracket 2 is a grid-shaped bracket, with sliders I21 fixed on both sides of the bracket 2. A vertical slide rail I22 is provided on the housing 1. The bracket 2 and the housing 1 are slidably connected via the sliders I21 and the slide rails I22. In this embodiment, four slide rails are provided on the housing, corresponding to four sliders on the bracket. The vertical movement of the bracket is achieved through the cooperation of the sliders and the slide rails.

[0027] In addition, in this embodiment, as Figure 3As shown, the vertical drive mechanism 3 includes a rack 31 vertically fixed on the housing 1, and a drive motor 32 fixed on the bracket 2. The output end of the drive motor 32 is equipped with a gear, which engages with the rack 31 through a transmission. In this embodiment, when it is necessary to control the vertical movement of the bracket to adjust the distance between adjacent brackets to meet the retrieval requirements, the drive motor is controlled to operate, thereby causing the output end of the drive motor to drive the gear to rotate, and then the bracket moves up and down under the meshing of the gear and rack. In addition, the drive motor is a geared motor, which can have a low speed and a large driving force, and can also provide a certain self-locking ability when it moves into position to maintain the stability of the bracket position.

[0028] As a further specific implementation, to determine the position of the bracket, the housing 1 is equipped with several photoelectric sensors that cooperate with the bracket 2. The photoelectric sensors are evenly spaced along the vertical direction of the housing. When a photoelectric sensor at a corresponding height is triggered, the vertical position of the bracket can be determined. As an optional alternative, the photoelectric sensors can be replaced with gratings. The bracket is equipped with a trigger plate that cooperates with the grating, thereby determining the position of the corresponding bracket based on the point where the grating is blocked by the trigger plate.

[0029] Example 3 provides a convenient microbial testing incubator. Based on Example 2, the sliding conductive structure 4 includes a pair of vertically parallel conductor strips 41 fixed inside the chamber 1. The two conductor strips 41 are respectively connected to the positive and negative terminals of a power supply. The bracket 2 is provided with sliding contacts that mate with the conductor strips 41, and these sliding contacts are connected to terminals 42. In this example, the drive motor is connected to the terminals, thereby providing power to the drive motor.

[0030] Specifically, such as Figure 5 As shown, the sliding contact includes a sleeve 43 fixedly mounted on the bracket 2, a contact 44 slidably mounted on the sleeve 43, and a spring I 45 between the contact 44 and the sleeve 43. The contact 44 is connected to the terminal 42 via a wire. During the up-and-down movement of the bracket, the contact remains in contact with the conductor strip under the elastic support of the spring I, thereby maintaining conductivity. In this embodiment, the contact can be a metal contact or a graphite contact.

[0031] Example 4 provides a convenient microbial testing incubator. Based on Example 3, the tray 5 has a slider II 51 at its bottom, and the bracket 2 has a slide rail II 52. The slider II 51 and slide rail II 52 slide in a sliding engagement. In this example, when the tray needs to be removed, pulling the tray causes the corresponding layer of the tray to be pulled outwards from the incubator body through the sliding engagement of the slider and slide rail, thus enabling the placement and removal of the culture container.

[0032] As a further optional real-time method, a lead screw 53 is rotatably mounted on the bracket, and a lead screw nut 54, which is driven by the lead screw 53, is located at the bottom of the tray 5. A driver, also driven by the lead screw 53, is mounted on the bracket. When it is necessary to move the tray out of the box to retrieve the culture container, the control button of the driver is pressed. The driver operates, driving the lead screw to rotate, thereby moving the tray along the slide rail II outward under the action of the lead screw and lead screw nut. This achieves automatic extension and retraction, resulting in a higher degree of automation.

[0033] Example 5: A convenient microbial testing incubator, based on Example 4, such as... Figure 4 As shown, the placement position 6 includes several circular grooves formed on the tray 5, and the elastic locking structure 7 includes several pressure plates 71 evenly spaced circumferentially within the circular grooves. A spring II 72 is provided between the pressure plates 71 and the circular grooves. In this embodiment, when storing the culture container, the side wall of the culture container is used to press the pressure plates outward, while simultaneously compressing the spring II. After the culture container is placed in position, the spring's restoring force pushes the pressure plates against the side wall of the culture container, thus determining the position of the culture container.

[0034] Example 6, as a further specific implementation, the front of the box 1 is open, and the opening is provided with a door 11 that can be closed. The door 11 is provided with a control plate 12, and the control plate 12 is electrically connected to the vertical drive mechanism 3.

[0035] In this embodiment, the control board can be a conventional microcontroller. A display controller is located on the front of the housing, connected to the microcontroller. Each bracket has a microcontroller board, electrically connected to the driver and drive motor 32. The microcontroller board can also be a conventional microcontroller, and both the microcontroller board and the control board have interconnected wireless communication modules, such as BLE Bluetooth modules, to achieve wireless communication. When it is necessary to control the height of the corresponding bracket to meet actual usage requirements, the display controller issues a command, which is wirelessly transmitted to the corresponding layer's microcontroller board. The microcontroller board then controls the corresponding drive motor to operate, thereby controlling the movement of the corresponding bracket. In addition, a button connected to the microcontroller board is provided on the tray. When it is necessary to move the tray of the corresponding layer out, the corresponding button is pressed. The microcontroller board transmits a control signal to the corresponding driver, which operates, driving the lead screw to rotate, thereby sending out the corresponding tray.

[0036] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
