Description

Technical Field

[0001] This utility model relates to the technical field of constant temperature incubation devices, specifically, to a water-jacketed constant temperature incubation device. Background Technology

[0002] A thermostat is a device commonly used in biological laboratories. Its function is to provide a constant temperature environment for culturing various cells, microorganisms, or tissues.

[0003] Currently, conventional electric heating constant temperature incubation devices directly heat the air, resulting in relatively poor temperature uniformity within the device. In contrast, water-jacketed electric heating constant temperature incubation devices have a water-storage tank installed around the outer perimeter of the incubation chamber. Water needs to be added to the tank before use. After the water is electrically heated, the temperature is conducted to the tank, raising the temperature of the incubation chamber. Therefore, the temperature uniformity is relatively better.

[0004] However, if the water level in the water-jacketed electric heating constant temperature incubator is too low during use, the temperature will drop, resulting in poor experimental results or termination. Therefore, it is necessary to pay close attention to the water level and add water in a timely manner. Utility Model Content

[0005] This invention proposes a water-jacketed constant temperature incubation device to solve the problem of constantly monitoring the water level and adding water in the prior art.

[0006] The technical solution of this utility model is as follows: A water-jacketed constant temperature incubation device includes a constant temperature incubation device body, the constant temperature incubation device body is provided with a display controller and a water storage tank, the water storage tank is installed inside the constant temperature incubation device body, the upper part of the water storage tank is equipped with a water inlet pipe and the lower part with a water outlet pipe, which are used to add water and drain water from the water storage tank, and also includes a liquid level sensor, a temperature sensor, an external water tank, a water pumping device, a buffer water tank, a normally closed solenoid valve, a liquid level sensor, and a temperature sensor.

[0007] A liquid level sensor is installed in the upper middle part of the water storage tank, below the position of the water inlet pipe. The liquid level sensor is electrically connected to the display controller to sense the liquid level in the water storage tank. A temperature sensor is installed in the middle of the water storage tank. The temperature sensor is electrically connected to the display controller to sense the temperature in the water storage tank. An external water tank is connected to the main body of the constant temperature incubation device. A water pumping device is connected to the external water tank and electrically connected to the display controller. A buffer water tank is connected to the water inlet pipe. The outlet of the water pumping device is connected to the buffer water tank. A normally closed solenoid valve is connected to the... A water inlet pipe is threadedly connected to the buffer tank. A level sensor is installed in the middle of the buffer tank and is electrically connected to the display controller to sense the water level in the buffer tank. A temperature sensor is also installed in the middle of the buffer tank and is electrically connected to the display controller to sense the water temperature in the buffer tank. The display controller starts or stops the pumping device based on the water level information transmitted by the level sensor. The display controller also starts or stops the normally closed solenoid valve based on the water level information from the level sensor and the comparison information between the temperature sensor.

[0008] To facilitate water heating in the buffer tank, preferably, a heater is also included. The heater is installed inside the buffer tank and is electrically connected to the display controller for heating the water in the buffer tank. The display controller can start or stop the heater by comparing the temperature information transmitted by temperature sensor one and temperature sensor two.

[0009] Preferably, the buffer water tank includes a water tank shell, an inlet pipe, an outlet pipe, and an inspection port.

[0010] The second water inlet pipe is installed at the upper part of the first water tank shell. The second water inlet pipe passes through the first water tank shell to the outside.

The water level and temperature in the inner storage tank are also detected by a sensor. If the water level drops but the temperature difference with the water in the buffer tank is not significant, a normally closed solenoid valve is activated to add water to the inner storage tank. Compared with the prior art, which requires frequent monitoring of the water level and manual addition if the inner storage tank is low on water, this invention automatically replenishes water by using an external water tank, a buffer tank, and a sensor to detect the water level in real time, eliminating the need for frequent monitoring of the water level.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1 to 6 As shown in this embodiment, a water-jacketed constant temperature incubation device includes a constant temperature incubation device body, which is equipped with a display controller 1 and a water storage tank 2. The water storage space of the water storage tank 2 is a C-shaped structure and is installed inside the constant temperature incubation device body. The upper part of the water storage tank 2 is equipped with a water inlet pipe 3 and the lower part with a water outlet pipe 4 for adding and discharging water into the water storage tank 2. It also includes a liquid level sensor 5, a temperature sensor 6, an external water tank, a water pumping device 7, a buffer water tank, a normally closed solenoid valve 8, a second liquid level sensor 9, and a second temperature sensor 10.

[0028] In this embodiment, the liquid level sensor 5 is installed in the upper middle part of the water storage tank 2, below the position of the inlet pipe 3. The liquid level sensor 5 collects the liquid level signal and is electrically connected to the display controller 1 to sense the liquid level of the water storage tank 2. The temperature sensor 6 is installed in the middle of the water storage tank 2. The temperature sensor 6 collects the temperature signal and is electrically connected to the display controller 1 to sense the temperature of the water storage tank 2. The external water tank is connected to the constant temperature incubation device body. The water pumping device 7 is connected to the external water tank and electrically connected to the display controller 1. The buffer water tank is connected to the inlet pipe 3. The outlet of the water pumping device 7 is connected to the buffer water tank. The normally closed solenoid valve 8 is connected to the inlet pipe 3. 3 is threadedly connected to the buffer water tank. The normally closed solenoid valve 8 is detachable and replaceable. The second liquid level sensor 9 is installed in the middle of the buffer water tank and is electrically connected to the display controller 1 to sense the liquid level in the buffer water tank. The second temperature sensor 10 is installed in the middle of the buffer water tank and is electrically connected to the display controller 1 to sense the water temperature in the buffer water tank. The display controller 1 starts or stops the pumping device 7 to pump water based on the liquid level information transmitted by the second liquid level sensor. The display controller starts or stops the normally closed solenoid valve 8 together based on the liquid level information of the first liquid level sensor, the comparison information of the first temperature sensor 6 and the second temperature sensor 10.

[0029] like Figures 1 to 5 As shown, when the level sensor 29 senses a decrease in the level of the buffer water tank, it will activate the pumping device 7 through the display controller 1 to pump water from the external water tank into the buffer water tank. The pumping will stop when the level is reached. In this embodiment, the pumping device 7 is a submersible pump installed in the external water tank, but other types of pumping equipment can also be used.

[0030] In this embodiment, to facilitate the heating of water in the buffer tank, a heater 101 is also included. The heater 101 is installed in the buffer tank and is electrically connected to the display controller 1. It is used to heat the water in the buffer tank. The display controller 1 can start or stop the heater 101 by comparing the temperature information transmitted by temperature sensor 6 and temperature sensor 10.

[0031] Because the external water tank is large in size and has a large water storage capacity, the inner water tank 2 does not need too much water to be replenished at one time. If the water in the external water tank is heated directly, the energy consumption will be relatively large. Therefore, for energy-saving considerations, a smaller buffer water tank is set up, so the heater 101 is installed in the buffer water tank.

[0032] like Figures 1 to 5As shown, in this embodiment, in order to minimize the impact on the constant temperature state within the constant temperature incubation device, two measures are taken for the normally closed solenoid valve 8 used to replenish water in the water storage tank 2. The first measure is that after the liquid level sensor 5 transmits information about the decrease in the liquid level of the water storage tank 2 to the display controller 1, the second measure is taken: the temperature sensor 6 and the temperature sensor 10 compare the water temperature of the water storage tank 2 and the buffer tank. If the two water temperatures are equal, the normally closed solenoid valve 8 is opened through the display controller 1 to add water to the water storage tank 2. If the two water temperatures are not equal, the display controller 1 compares the temperature sensor 6 and the temperature sensor 10. If the temperature information of the temperature sensor 6 is greater than or equal to the temperature information of the temperature sensor 10, the heater 101 is not started. If the temperature information of the temperature sensor 6 is less than the temperature information of the temperature sensor 10, the heater 101 is started. After the temperatures are equal, heating is stopped and the normally closed solenoid valve 8 is opened.

[0033] like Figures 1 to 5 As shown, in this embodiment, the buffer water tank includes a tank shell 201, an inlet pipe 202, an outlet pipe 203, and an inspection port 204. The inlet pipe 202 is installed at the upper part of the tank shell 201, passing through the tank shell 201 to the outside. The outlet pipe 203 is installed at the bottom of the tank shell 201, passing through the tank shell 201 to the outside and connected to the normally closed solenoid valve 8. The inspection port 204 is installed on the upper surface of the tank shell 201 and is mainly used for maintenance and repair of the equipment inside the buffer water tank.

[0034] like Figures 1 to 3 As shown, in this embodiment, the external water tank includes a water tank housing 301, an inlet 302, and an outlet pipe 303. The inlet 302 is installed on the upper surface of the water tank housing 301, and the outlet pipe 303 is installed on one side of the upper end of the water tank housing 301. The outlet pipe 303 passes through the water tank housing 301 to the outside and is threadedly connected to the inlet pipe 202. It has a detachable function, so that if the entire external water tank or the buffer water tank is damaged, it can be replaced as a whole.

[0035] In this embodiment, a transparent liquid level display window 401 is provided on the side of the external water tank to facilitate observation of the water level. Since the external water tank serves as a "backup water source" for the inner water tank 2 and the buffer water tank, and has an insulated and hard opaque outer shell, it is necessary to add a liquid level display window 401 to observe the water level.

[0036] In this embodiment, for ease of movement, multiple self-locking rollers 501 are installed at the bottom of the constant temperature incubation device body, which can achieve self-locking when fixed.

[0037] Working principle: Place the organism to be cultured into the water-jacketed constant temperature culture device. For the first use of the water-jacketed constant temperature culture device, first loosen the normally closed solenoid valve 8 that is threaded to the outlet pipe 203, and directly add water to the water storage tank 2 through the inlet pipe 3. Observe the liquid level in the water storage tank 2. Stop adding water after the liquid level is reached, reconnect the interface, and then add water to the external water tank through the inlet 302. Pay attention to the liquid level display window 401.

[0038] Turn on the power, set the constant temperature on the display controller 1, and at the same time, after the liquid level sensor 2 9 is sensed, the display controller 1 starts the water pumping device 7 to pump water into the buffer water tank through the water outlet pipe 303. The pumping stops when the water is full. At the same time, the liquid level sensor 1 5 and the liquid level sensor 2 9 monitor the water level in real time.

[0039] After the water-jacketed constant temperature incubator has been running for a long time, the liquid level in the inner water tank 2 gradually decreases. When the liquid level sensor 5 transmits the decrease, temperature sensors 6 and 10 compare the water temperatures in the inner water tank 2 and the buffer tank. If the temperatures are the same, the normally closed solenoid valve 8 opens, adding water to the inner water tank 2. If the water temperature in the buffer tank is greater than or equal to the water temperature in the inner water tank 2, the heater 101 is not activated. The normally closed solenoid valve 8 opens when the water temperature in the buffer tank drops to the same level as the water temperature in the inner water tank 2. If the water temperature in the buffer tank is lower than the water temperature in the inner water tank 2, the heater 101 is activated. The normally closed solenoid valve 8 opens when the water temperature in the inner water tank reaches the same level. The automatic water replenishment is completed when the liquid level in the inner water tank 2 is increased to a level higher than that of the liquid level sensor 5 and the normally closed solenoid valve 8 closes.

[0040] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
