Abstract
Description
Technical Field
[0001] The present application relates to the technical field of laboratory equipment, and in particular to a water bath with a rapid cooling function. Background Art
[0002] Water baths are primarily used in laboratories for distilling, drying, concentrating, and soaking chemicals or biological products. They can also be used for constant temperature heating and other temperature testing. They are essential tools for biology, genetics, virology, aquaculture, environmental protection, medicine, health, laboratories, analytical labs, and educational research. When a water bath needs to be cooled, the current method is to open the lid and add water to the bath, using a graduated cylinder and scale to precisely control the amount of water added to achieve the desired temperature.
[0003] Regarding the above-mentioned related technologies, the inventors believe that there are the following defects: during the cooling process of the water bath, in order to control the cooling value, it is necessary to accurately control the amount of water added to the water bath, but the volume of the water bath is limited. The amount of water added during the temperature control process is limited by the volume of the water bath. When a larger cooling rate is required, a large amount of cold water needs to be added to the pot. When the cold water and hot water are evenly mixed, in order to prevent the water in the water bath from overflowing, the excess water in the pot needs to be scooped out, and then cold water needs to be added again to cool down until the water in the water bath drops to the required temperature. This cooling step is cumbersome. Utility Model Content
[0004] In order to solve the problem of cumbersome cooling steps during the cooling process of a water bath, the present application provides a water bath with a rapid cooling function.
[0005] The present application provides a water bath with a rapid cooling function using the following technical solutions:
[0006] A water bath with a rapid cooling function comprises a shell, a pot body fixed inside the shell, and a control box arranged on one side of the shell, a closed channel formed between the shell and the pot body, the channel and the pot body being not connected to each other, the channel being used for circulating cooling liquid, a liquid inlet being provided on one side of the shell, a first tube being threadedly connected to the liquid inlet, the first tube being connected to a liquid inlet hose, a liquid outlet being provided on the other side of the shell, a second tube being threadedly connected to the liquid outlet, the second tube being connected to a liquid outlet hose, a peristaltic pump being provided on one side of the shell, and the liquid inlet hose being placed in a cavity of a pump head of the peristaltic pump.
[0007] By adopting the above technical solution, when the water bath needs to be cooled, one end of the liquid inlet hose is placed in the cavity of the peristaltic pump head, and the end of the liquid inlet hose away from the shell is placed in cold water. The peristaltic pump switch is turned on, and cold water is passed into the channel. The cold water contacts the pot body and cools the water in the pot body through heat transfer. Under the action of pressure, the cold water is discharged from the liquid outlet hose through the channel, thereby completing the cooling of the water in the water bath. Compared with the existing cooling method, this solution cools down by circulating cold water, which is simple to operate and has a fast cooling speed.
[0008] Optionally, a flow sensor is provided in the first tube, a temperature sensor is provided in the pot body, and a display screen for monitoring the flow rate and the temperature in the water bath is provided on one side of the control box.
[0009] By adopting the above technical solution, the display screen is connected to the flow sensor and the temperature sensor. During the cooling process, the internal temperature data of the water bath is displayed on the display screen in real time, and the cold water flow rate is displayed on the display screen in real time, which is convenient for experimenters to observe specific data.
[0010] Optionally, the pot body is integrally formed with a heat dissipation plate, one end of the heat dissipation plate is located inside the pot body, and the other end is located inside the channel.
[0011] By adopting the above technical solution, the heat sink is a copper plate, and the thermal conductivity of the copper plate is better than that of the pot body material. When the cold water circulates in the channel, when the cold water passes through the heat sink, the heat of the liquid in the pot body is taken away through the placement of heat transfer, thereby accelerating the cooling speed.
[0012] Optionally, the heat dissipation plate is wavy in shape.
[0013] By adopting the above technical solution, the heat dissipation area of the heat dissipation plate is increased during the cooling process, thereby improving the cooling efficiency.
[0014] Optionally, chamfers are provided at the inner corners of the channel.
[0015] By adopting the above technical solution, arc-shaped chamfers are provided at the corners inside the channel, which can reduce the resistance of the cold water at the corners when the cold water passes through the corners, making the cold water flow more smoothly.
[0016] Optionally, a detachable rack is provided in the pot body, and a plurality of through holes for placing test tubes are opened on the rack.
[0017] By adopting the above technical solution, when it is necessary to heat test tubes and other items that are easy to tip over, the test tubes are passed through the through holes on the rack. The through holes can prevent the test tubes in the water bath from tipping over and prevent the dangerous liquids in the test tubes from flowing out, causing safety hazards. This increases the applicability of the water bath and increases the safety during the experiment.
[0018] Optionally, a pot cover is provided on the pot body.
[0019] By adopting the above technical solution, the experimenters covered the pot when heating items, which reduced the temperature loss during the heating process of the water bath and prevented the liquid or water in the water bath from splashing out during use.
[0020] Optionally, the pot cover is made of a transparent material, and a lighting lamp is provided above the pot cover.
[0021] By adopting the above technical solution, when conducting dangerous experiments, the pot lid needs to be covered to prevent dangerous liquids from splashing. The transparent pot lid makes it easy for experimenters to observe the experimental process and also ensures safety during the experiment. The lighting lamp has a built-in battery, and the setting of the lighting lamp makes it easy for experimenters to observe the situation in the water bath pot more clearly in a dark environment.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By passing cold water into the channel outside the pot, the liquid in the pot is cooled by heat transfer. This solution cools the water faster and has simple steps. The temperature sensor and flow sensor can monitor the temperature of the liquid in the water bath and the flow of cold water in real time.
[0024] 2. The setting of chamfers in the channel and the setting of wavy heat dissipation plates reduce the resistance of cold water at the corners of the channel, making the cold water flow more smoothly in the channel, further accelerating the cooling speed and further improving the cooling efficiency.
[0025] 3. The detachable storage rack set in the pot body makes it convenient for the experimenter to place the items to be heated during the experiment, and it is convenient for the experimenter to place easy-to-tip items such as test tubes, making the use of the water bath pot more convenient and flexible.

[0030] The following is combined with Figure 1-2 This application is described in further detail.
[0031] The embodiment of the present application discloses a water bath with a rapid cooling function.
[0032] Reference Figure 1 A water bath with a rapid cooling function includes a housing 1, a pot body 2 fixed within the housing 1, and a control box 3 disposed on one side of the housing 1. A sealed channel 4 is formed between the housing 1 and the pot body 2. Channel 4 is used to circulate cold water. Channel 4 is not connected to the interior of the pot body 2. During the cooling process, cold water is introduced into channel 4. The cold water contacts the pot body 2 and removes the dissipated heat through heat transfer, thereby cooling the liquid in the pot body 2. Circular chamfers 16 are provided within channel 4 to reduce the resistance of the cold water at the corners of channel 4, ensuring smoother flow of the cold water within channel 4.
[0033] Reference Figure 1 and Figure 2 A liquid inlet 5 is provided on one side of the shell 1, and a first tube 6 is threadedly connected to the liquid inlet 5. The first tube 6 is connected to a liquid inlet hose 7. A flow sensor 12 is provided in the first tube 6. The flow sensor 12 is used to detect the flow of cold water. During the cooling process, the cold water is transmitted into the channel 4 through the liquid inlet hose 7 for circulation. The cold water contacts the pot body 2 and reduces the temperature of the liquid in the pot body 2 through heat transfer.
[0034] Reference Figure 1 and Figure 2 A peristaltic pump 11 is provided on one side of the housing 1, and a liquid inlet hose 7 is placed in the pump head cavity of the peristaltic pump 11. When the peristaltic pump 11 is turned on, the peristaltic pump 11 draws cold water into the liquid inlet hose 7, causing the cold water to circulate inside the channel 4. The cold water in the channel 4 removes the heat of the pot body 2 through heat transfer, thereby cooling the liquid in the pot body 2. A liquid outlet 8 is provided on the other side of the housing 1. A second tube 9 is threadedly connected to the liquid outlet 8, and a liquid outlet hose 10 is connected to the second tube 9. During the cooling process, cold water circulates through the channel 4, and the cold water in the channel 4 is discharged from the liquid outlet hose 10 under the action of pressure.
[0035] Reference Figure 1 and Figure 2A heating tube for heating is provided at the bottom of the pot body 2, and a temperature sensor 13 is provided inside the pot body 2. The temperature sensor 13 is used to detect the temperature of the liquid in the pot body 2, detect the temperature data during the heating process of the water bath, and detect the temperature change during the cooling process. The setting of the temperature sensor 13 can monitor the temperature of the water in the water bath in real time.
[0036] Reference Figure 1 The pot body 2 is integrally formed with a heat sink 15, one end of the heat sink 15 is located in the pot body 2, and the other end is located in the channel 4. The heat sink 15 is made of copper plate, which has a better thermal conductivity. During the cooling process, when cold water passes through the heat sink 15, it can take away more heat in the pot body 2 through heat transfer. The shape of the heat sink 15 is wavy, which increases the heat dissipation area. During the cooling process, when cold water passes through the heat sink 15, it can absorb more heat, thereby accelerating the cooling speed of the water in the water bath and reducing the time required for cooling.
[0037] Reference Figure 1 A detachable rack 17 is provided in the pot body 2. The rack 17 has a number of through holes for placing test tubes. During the experiment, when it is necessary to heat the test tubes that are easy to tip over, the test tubes are placed in the through holes of the rack 17 to prevent the test tubes from tipping over and the dangerous liquid in the test tubes from causing harm to the experimenters, and it is also convenient for the experimenters to operate.
[0038] Reference Figure 1 and Figure 2 The pot body 2 is provided with a matching pot cover 18, which is made of a transparent material. A lighting lamp 19 is provided above the pot cover 18, and the lighting lamp 19 has a built-in battery. During the experiment, when the water bath needs to be heated, the pot cover 18 is used to reduce heat loss during the heating process, reducing the power consumption of the equipment and achieving a better heating effect. When heating some dangerous liquids, the setting of the pot cover can prevent the dangerous liquid from splashing during the heating process, thereby improving the safety of the experimenter during the operation. When doing some impurity detection experiments, it is necessary to prevent the liquid to be detected from being contaminated by the outside world. The setting of the water bath pot cover 18 prevents the entry of external pollutants and improves the accuracy of the experiment. The transparent pot cover 18 makes it easy for the experimenter to observe the experimental process. The lighting lamp 19 above the pot cover 18 allows the experimenter to observe the experimental process in insufficient light, which helps to promote the smooth completion of the experiment.
[0039] Reference Figure 1 and Figure 2A control box 3 is provided on one side of the shell 1, and a display screen 14 is provided on one side of the control box 3 for monitoring the temperature inside the pot body 2 and the flow rate of cold water in the channel 4. During the heating process, the real-time data can be intuitively understood on the display screen 14, which is convenient for controlling the heating temperature. During the cooling process, the flow rate of cold water in the channel 4 can be monitored in real time on the display screen 14, and the temperature inside the pot body 2 can be monitored in real time on the display screen 14, which is convenient for the experimenter to observe the data.
[0040] The implementation principle of a water bath with a rapid cooling function in the embodiment of the present application is as follows: when the water in the water bath needs to be cooled, the liquid inlet hose 7 is placed into the pump head cavity of the peristaltic pump 11, and the end of the liquid inlet hose 7 away from the liquid inlet 5 is placed in cold water. The peristaltic pump 11 is turned on to pump cold water into the channel 4, removing heat from the water bath body 2 through heat transfer. The water in the channel 4 is discharged from the end of the liquid outlet pipe away from the housing 1. During the cooling process, the peristaltic pump speed is adjusted based on the temperature data and water flow data on the display to control the cooling temperature and cooling speed.
