Description

Technical Field

[0001] The utility model relates to the technical field of water bath pots, in particular to a multiple protection device for water bath pots. Background Art

[0002] Water baths are mainly used for distillation, drying, concentration, and soaking of chemicals or biological products in laboratories. They can also be used for constant temperature heating and other temperature tests. They are essential tools in biology, genetics, viruses, aquaculture, environmental protection, medicine, health, laboratories, analysis rooms, education and scientific research.

[0003] In actual use, existing water baths are equipped with water level sensors to prevent dry-burning caused by low water levels, which could damage the heating tubes. These sensors monitor the situation and sound an alarm if dry-burning occurs. However, this can easily lead to persistent dry-burning when staff are temporarily absent. Furthermore, with only one protection mechanism, the level sensor cannot accurately detect low water levels if the level sensor fails, resulting in poor protection. Therefore, we propose a multi-protection device for water baths. Utility Model Content

[0004] The purpose of the utility model is to provide a multiple protection device for a water bath pot, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a water bath multi-protection device, comprising a water bath body, a heating tube and a liquid level sensor being fixed to one side wall of the inner cavity of the water bath body, and a controller and an alarm being fixed to the outer wall of the water bath body;

[0006] A protective component is fixed to the other side wall of the inner cavity of the water bath body, and the protective component includes a fixed shell, a lifting column is passed through the top of the fixed shell, a sliding block is fixed to the tail end of the lifting column, and the sliding block is slidably arranged in the inner cavity of the fixed shell, a connecting frame is fixed to the top of the lifting column, and a float is fixed at both ends of the connecting frame. A pressure sensor is fixed to the bottom of the inner cavity of the fixed shell, and a relay switch is fixed to one side wall of the water bath body, and an outer wall of the relay switch is connected to an electric wire.

[0007] By adopting the above technical solution, during the use of the water bath body, the water level in the water bath body can be monitored by the liquid level sensor. When the water level is too low, a signal will be fed back to the controller, thereby activating the alarm to warn the staff to add water or cut off the power. If the liquid level sensor fails and the float ball rises after water is added to the water bath body, and then the power is turned on, the lifting column will drive the sliding block to rise. When dry burning occurs, the water level is too low. At this time, the sliding block drops and presses on the pressure sensor, which will feed back a signal to the controller, and the controller will control the power-off switch to cut off the power, thereby achieving double protection and avoiding continuous dry burning.

[0008] As a preferred embodiment of the present invention, a liquid pump is fixed to the bottom of the fixed shell, and both ends of the liquid pump are fixedly connected to conduits.

[0009] By adopting the above technical solution, the liquid pump can use the conduit on one side to draw water, and then discharge it along the conduit on the other side, so that the water in the water bath body can be circulated, thereby improving the uniformity of water heating in the water bath body, which is beneficial to improving the subsequent water bath effect.

[0010] As a preferred embodiment of the present invention, the position of the liquid level sensor is higher than the height of the heating tube to ensure the liquid level monitoring effect.

[0011] As a preferred embodiment of the present invention, a drain valve is fixedly connected to the lower side of one side wall of the water bath body.

[0012] By adopting the above technical solution and setting the drain valve, the water in the water bath body after use can be drained out.

[0013] As a preferred embodiment of the present invention, the alarm is a buzzer.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The technical solution of the present application is a multi-protection device for a water bath. By arranging a protection component on the inner wall of the water bath body, when the water level is too low, the float drops, causing the sliding block to drop and pressurize the pressure sensor. The controller then controls the relay switch to cut off the power, thereby preventing dry boiling. In addition, the device cooperates with the liquid level sensor for detection, thereby achieving multiple protections and improving the protection effect.

[0016] The liquid pump can pump water through the conduit on one side and then discharge it through the conduit on the other side, so that the water in the water bath can be circulated, thereby improving the uniformity of water heating in the water bath, which is beneficial to improving the subsequent water bath effect.

[0024] See also Figure 1-3 The utility model provides a technical solution: a multi-protection device for a water bath, comprising a water bath body 1, a heating tube 11 and a liquid level sensor 12 fixed to one side wall of the inner cavity of the water bath body 1, and a controller 13 and an alarm 14 fixed to the outer wall of the water bath body 1;

[0025] A protective assembly 2 is fixed to the other side wall of the inner cavity of the water bath body 1. The protective assembly 2 includes a fixed shell 21. A lifting column 22 is passed through the top of the fixed shell 21. A sliding block 23 is fixed to the tail end of the lifting column 22, and the sliding block 23 is slidably arranged in the inner cavity of the fixed shell 21. A connecting frame 25 is fixed to the top of the lifting column 22. Floats 26 are fixed at both ends of the connecting frame 25. A pressure sensor 24 is fixed to the bottom of the inner cavity of the fixed shell 21. A relay switch 15 is fixed to one side wall of the water bath body 1. The outer wall of the relay switch 15 is connected to an electric wire 16.

[0026] It should be noted that the wire 16 is electrically connected to the water bath body 1 through the relay switch 15, the signal output end of the liquid level sensor 12 and the pressure sensor 24 is connected to the signal input end of the controller 13, and the signal output end of the controller 13 is connected to the signal input end of the alarm 14 and the relay switch 15 respectively;

[0027] During actual use, the water bath body 1 can first monitor the water level in the water bath body 1 through the liquid level sensor 12. When the water level is too low, a signal will be fed back to the controller 13, thereby activating the alarm 14 to alarm, warning the staff to add water or cut off the power. If the liquid level sensor 12 fails and the float 26 is raised after water is added to the water bath body 1, and then the power is turned on, the lifting column 22 will drive the sliding block 23 to rise. When dry burning occurs, the water level is too low. At this time, the sliding block 23 drops and presses on the pressure sensor 24, which will feed back a signal to the controller 13, and the controller 13 will control the power-off switch 15 to cut off the power, thereby achieving double protection and avoiding continuous dry burning.

[0028] Furthermore, a drain valve 17 is fixedly connected to the lower side of one side wall of the water bath body 1. The setting of the drain valve 17 enables the water in the water bath body 1 to be drained out after use.

[0029] Furthermore, the position of the liquid level sensor 12 is higher than the height of the heating tube 11, thereby ensuring the liquid level monitoring effect.

[0030] It is worth mentioning that the alarm 14 is a buzzer, which can emit a buzzing alarm sound, thereby alerting the staff.

[0031] like Figure 1 and 2 As shown; a liquid pump 27 is fixed to the bottom of the fixed shell 21, and both ends of the liquid pump 27 are fixedly connected to a conduit 28;

[0032] The liquid pump 27 can pump water through the conduit 28 on one side and then discharge it along the conduit 28 on the other side, so that the water in the water bath body 1 can be circulated, thereby improving the uniformity of water heating in the water bath body 1, which is beneficial to improving the subsequent water bath effect.

[0033] The implementation principle of the multi-protection device of the water bath pot of the present application is as follows: in actual use, when the water bath pot body 1 is in use, the water level in the water bath pot body 1 is first monitored by the liquid level sensor 12. When the water level is too low, a signal is fed back to the controller 13, thereby activating the alarm 14 to alarm, warning the staff to add water or cut off the power. If the liquid level sensor 12 fails and water is added to the water bath pot body 1, the float 26 will rise, and then the power will be turned on. At this time, the lifting column 22 will drive the sliding block 23 to rise. When dry boiling occurs, the water level Too low, at this time the sliding block 23 descends and presses on the pressure sensor 24, which will feed back a signal to the controller 13, so that the controller 13 will control the power-off switch 15 to cut off the power, thereby achieving double protection to avoid continuous dry burning. At the same time, during the heating process of the water in the water bath body 1, the liquid pump 27 can use the conduit 28 on one side to pump water, and then lead it out along the conduit 28 on the other side, so that the water in the water bath body 1 can be circulated, thereby improving the uniformity of the water heating in the water bath body 1, which is beneficial to improving the subsequent water bath effect.

[0034] In addition, the components included in the multi-protection device for a water bath pot of the utility model are all universal standard parts or components known to those skilled in the art. Their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted monitoring computers and power supplies, are connected through wires. For specific connection methods, reference should be made to the following working principle. The electrical connection is completed in the order of working between the electrical components. The detailed connection methods are well-known technologies in this field. The following mainly introduces the working principles and processes, and no longer explains the electrical control.
