Description

Technical Field

[0001] This utility model relates to the field of biological culture technology, specifically to a biological culture water replenishment device. Background Technology

[0002] Biological incubators need to maintain internal humidity. The traditional operating method is to place a shallow tray filled with pure water at the bottom of the biological incubator, and maintain the internal humidity through natural evaporation. For example, Chinese Patent 202411111463.5 discloses a microbial culture device, including a microbial incubator body, a water container, and a translation mechanism. The microbial incubator body is provided with a placement plate for placing culture dishes, and the placement plate is provided with honeycomb holes.

[0003] Currently, in biological incubators that do not have automatic water replenishment and humidity control, shallow water trays are still used to store water and maintain internal humidity through evaporation.

[0004] However, shallow trays require frequent opening of the bioincubator to add water. While replacing them with deep trays increases water capacity and reduces the frequency of water additions, when the bioincubator's internal control system needs to lower the temperature (and thus reduce relative humidity), the deeper tray, due to its larger heat capacity, cools down more slowly than the shallower tray. This results in continuous water evaporation, which counteracts the system's adjustment, leading to large humidity fluctuations and inaccurate control. Therefore, how to maintain evaporation in the shallow tray without frequent water additions is a technical problem that needs to be solved. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a biological culture water replenishment device to solve the technical problem of how to maintain shallow water evaporation without frequent water replenishment in the prior art.

[0019] 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.

[0020] To address the technical problem of maintaining shallow water evaporation without frequent water replenishment, this invention provides a biological culture water replenishment device. This device utilizes a water storage box as an additional pure water reservoir. With a one-way valve providing unidirectional flow and closure, it offers an independent water storage space to prevent external bacterial contamination. Combined with a pump assembly, a timer switch replenishes the shallow water tray in a timed and quantitative manner, effectively extending the usage time of a single water storage cycle, reducing the frequency of water replenishment, and maintaining shallow water evaporation through surface water storage and evaporation replenishment in the shallow water tray.

[0021] It should be noted that the biological culture water replenishment device described in this utility model is used in, but not limited to, biological incubators. For ease of explanation, this utility model only uses the application of the biological culture water replenishment device in a biological incubator as an example. The principle of the biological culture water replenishment device in other types of equipment is essentially the same as that in biological incubators, and will not be described in detail here.

[0022] Please see Figure 1-6 This utility model provides a biological culture water replenishment device, which includes a base 1, a shallow water tray 2, a water storage box 3, a water pump assembly 4, and a time control switch 5. The base 1 has a slot 101, and the top of the slot 101 has a water outlet 102. The slot 101 is located at the top of the base 1 and extends through the right side of the base 1, allowing the shallow water tray 2 to be inserted into the top of the base 1 for water evaporation. The shallow water tray 2 is inserted into the slot 101 and placed below the water outlet 102. The shallow water tray 2 has a notch that matches the water outlet 102, allowing it to be inserted into the notch and suspended inside the shallow water tray 2 for downward water release. Water is added to the shallow water tray 2. A water storage box 3, installed on the base 1, stores pure water. The water storage box 3 is sealed to prevent external microbial contamination and stores clean pure water. A water pump assembly 4 is located inside the base 1 and has a suction end and a supply end. The suction end is inserted into the inside of the water storage box 3, and the supply end is connected to the discharge end 102 via a one-way valve 401. The one-way valve 401 allows water to be drawn out from the inside and prevents external water from flowing back into the water storage box 3. A timer switch 5 is electrically connected to the water pump assembly 4 and is used to periodically start the water pump assembly 4 to pump and deliver water. The timer switch 5 controls the start of the water pump assembly 4 at regular intervals. The sealed water storage box 3 stores pure water, serving as an additional extension of the water storage in the shallow water tray 2. The shallow water tray 2 maintains its original shallow water accumulation and evaporates, while the water storage box 3 is a space separated from the shallow water tray 2 and does not directly contact the outside air. When the water pump assembly 4 is activated, pure water in the water storage box 3 can be replenished into the shallow water tray 2, thereby extending the usage time of a single water storage. In addition, the entire biological culture water replenishment device can be placed at the bottom of the biological culture box in the traditional way, without the need for internal modification of the biological culture box. It can be directly used in the existing biological culture box, and solves the problem of the existing shallow water tray requiring frequent opening of the biological culture box to add water.

[0023] Understandably, the time switch 5 can be an electronic time switch, controlled by a microprocessor (MCU), and set via an LCD screen (LCD) and buttons. The model can be a mature finished time switch available on the market, and its electrical connection and specific control method are all existing mature technologies, which will not be elaborated on here. For ease of use, a battery 501 is also installed in the base 1 to provide power to the water pump assembly 4 and the time switch 5.

[0024] In one embodiment, please refer to Figure 1 and Figure 2 To adjust the height of the entire biological culture water replenishment device according to the available space inside the biological culture chamber, and to avoid it being too tall to fit inside the biological culture chamber, the biological culture water replenishment device also includes a water storage bladder 6, which is located at the bottom of the water storage box 3 and has a flexible outer peripheral wall 601, allowing it to have a compressed folded state and an unfolded stretched state. When there is sufficient space inside the biological culture chamber, the entire water storage bladder 6 can be fully stretched out. At this time, the combination of the water storage bladder 6 and the water storage box 3 can have the maximum additional water storage capacity. When the space inside the biological culture chamber is limited, the stretching height of the water storage bladder 6 can be appropriately adjusted according to the height of the space, so as to match the corresponding space for use.

[0025] Understandably, the bottom of the water bladder 6 and the water storage box 3 are completely connected, forming an internally connected water storage chamber.

[0026] In one embodiment, please refer to Figure 1 and Figure 2 To provide bottom support for the extension and retraction of the water bladder 6 and improve its stability, a support assembly 7 is also included. This assembly is installed on the base 1 and includes a telescopic component 71 and a support component 72. The telescopic component 71 is installed on the base 1, and its telescopic end abuts against the support component 72. The support component 72 is connected to the bottom of the water bladder 6 and is used for bottom support and adjustment of the compression and expansion of the water bladder 6. By adjusting the extension and retraction of the telescopic component 71, the bottom support point is adjusted, and the bottom position of the water bladder 6 is restricted after the water bladder 6 is stretched.

[0027] Furthermore, to facilitate adjustment, the telescopic component 71 includes a screw 711 and a pad 712. The base 1 has several screw holes 103. The screw 711 is threadedly connected to the screw holes 103 one by one, and the pad 712 is connected to the bottom end of the screw 711 one by one. There are four screw holes 103 and four screws 711. The height can be adjusted by rotating the adjusting screw 711 to extend or retract.

[0028] Furthermore, the support member 72 includes an outer frame 721, on which through holes 722 corresponding to the screws 711 are opened. The screws 711 are inserted into the corresponding through holes 722. The outer frame 721 is connected to the bottom of the water storage bladder 6. Pulling the outer frame 721 can stretch the water storage bladder 6, and conversely, pushing the outer frame 721 upward can compress the water storage bladder 6.

[0029] For further details, please refer to Figure 3The top of the water storage box 3 is provided with a water inlet 301, and a first sealing plug 302 is inserted into the water inlet 301. By pulling out the first sealing plug 302, pure water can be poured into the water storage box 3 and the water storage bladder 6 through the water inlet 301.

[0030] For further details, please refer to Figure 3 The bottom of the water storage bladder 6 is provided with a drain port 602, and a second sealing plug 603 is inserted into the drain port. By pulling out the second sealing plug 603, the remaining pure water inside can be discharged out through the drain port 602.

[0031] In one embodiment, please refer to Figure 4 , Figure 5 and Figure 6 To provide a water pumping function, the water pump assembly 4 includes a micro water pump 41 and a water pumping pipe 42. The micro water pump 41 is installed inside the base 1, the water pumping pipe 42 is connected to the water inlet of the micro water pump 41, and the water outlet of the micro water pump 41 is connected to the one-way valve 401. By starting the micro water pump 41, water is pumped through the water pumping pipe, pumped through the one-way valve 401, and flows into the water outlet 102, and discharged into the shallow water tray 2.

[0032] Understandably, the time control switch 5 is electrically connected to the micro water pump 41 to control the micro water pump to start at regular intervals.

[0033] Furthermore, to prevent the flexible water-drawing pipe 42 from coiling or folding during the extension and retraction of the water storage bladder 6, the water pumping assembly 4 also includes a bracket 43. The bracket 43 is sleeved on the outside of the water-drawing pipe 42 and hinged to the inner top wall of the water storage box 3. The rigid bracket provides external support for the water-drawing pipe 42. During the extension and retraction of the water storage bladder 6, the bracket can rotate upwards, so that the bottom end of the water-drawing pipe 42 can always be close to the inner bottom wall of the water storage chamber for bottom water pumping.

[0034] Furthermore, the inner bottom wall of the drain end 102 is inclined downwards, and a number of drain holes 104 are provided at the bottom of the drain end 102. The inclined bottom surface prevents water from accumulating inside, and the water is drained outwards evenly through the drain holes 104.

[0035] To better understand this utility model, the following is combined with... Figures 1 to 6The technical solution of this utility model is described in detail as follows: Based on the height of the bottom layer of the biological incubator, first adjust the height of the water storage bladder 6. To adjust the height of the water storage bladder 6, directly rotate the screw 711 to extend and retract it, adjust the position of the pad 712, and move the outer frame 721 accordingly to unfold the water storage bladder 6. After adjusting the height of the water storage bladder 6, remove the first sealing plug 302 and pour pure water into the water storage box 3 and the water storage bladder 6 through the water inlet 301, and then reinstall the first sealing plug 302. Finally, install the shallow water tray 2 into the slot 101 and pour an appropriate amount of pure water into the shallow water tray 2. Set the timer switch 5 to replenish water at a set time, and start the micro water pump 41 at a set time. Use the water pump pipe 42 to draw water from the water storage chamber and inject it into the shallow water tray 2 through the one-way valve 401 and the drain end 102 to replenish water.

[0036] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
