[0001] This utility model relates to the field of constant temperature and humidity chamber technology, specifically a constant temperature and humidity chamber with a visual liquid level monitoring water supply system. Background Technology

[0002] A constant temperature and humidity chamber is a precision device that can simulate a specific temperature and humidity environment and maintain the stability of that environment over a long period of time. It is widely used in industrial testing, scientific research experiments, biological culture, aging of electronic components and other scenarios. Its core function is to provide "controllable, stable and repeatable" temperature and humidity conditions for test samples or experimental objects.

[0003] The constant temperature and humidity chamber has an internal humidification structure, so it needs an external water tank to continuously supply water. However, when the water level in the tank drops to a certain level, it will affect its use. Most current constant temperature and humidity chambers have built-in water tanks, which need to be opened regularly to check the water level. Even with an external transparent water tank, the equipment may still malfunction due to insufficient water during operation if the water level is not checked in time. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a constant temperature and humidity chamber with a visual liquid level monitoring water supply system. This solves the problem that most current constant temperature and humidity chambers have built-in water tanks, which require periodic opening to check the internal water level. Even with external transparent water tanks, the equipment may malfunction due to insufficient water during operation if the water level is not checked in time.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a constant temperature and humidity chamber with a visual liquid level monitoring water supply system, comprising a main body and a water tank mechanism;

[0006] A placement slot is provided at the rear of the top of the main body of the equipment, and the water tank mechanism is detachably installed inside the placement slot;

[0007] The water tank mechanism includes a device base frame adapted to the outline of the placement slot. A transparent plastic water storage tank is fixedly connected to the top of the device base frame. A circuit board is installed inside the device base frame. PCB contacts are provided on the rear part of the upper surface of the circuit board. A vertical pipe extending into the water storage tank is vertically fixedly connected inside the device base frame and above the PCB contacts. A sliding rod is vertically slidably connected inside the vertical pipe. A float is fixedly connected to the top of the sliding rod. A buzzer is installed on the circuit board.

[0008] When the slide bar is not under force, its bottom end contacts the PCB contact.

[0009] Furthermore, a plurality of positioning protrusions are fixedly connected to the bottom of the placement groove, and a plurality of slots corresponding to and adapted to the plurality of positioning protrusions are formed on the bottom of the device frame.

[0010] Furthermore, the top of the water storage tank is fixedly connected to multiple lifting handles, and the lower part of the front surface of the water storage tank is provided with a limit scale.

[0011] Furthermore, a sound outlet is provided on the front surface of the device's bottom frame at the position of the buzzer.

[0012] Furthermore, a water pipe connector is connected to one side surface of the water storage tank, and a vertically arranged pipe groove is opened on one side surface of the main body of the equipment. Multiple pipe clamps are fixedly connected at even intervals along the length of the pipe groove. A water supply pipe is connected to the water inlet of the main body of the equipment, and the other end of the water supply pipe extends upward through the pipe groove and connects to the water pipe connector.

[0013] Furthermore, multiple support blocks are fixedly connected to the bottom of the main body of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This constant temperature and humidity chamber with a visual liquid level monitoring water supply system, through the setting of a water tank mechanism, supplies water to the device. Inside the water tank mechanism is a float ball that can float on the water surface. Its position changes according to the height of the water level. When the water level in the storage tank is lower than the limit, the sliding rod at the bottom of the float ball will touch the PCB contact on the circuit board inside the bottom frame of the device, thereby triggering an alarm and activating a buzzer to remind the staff that the water level is insufficient, thus preventing problems caused by insufficient water during the operation of the equipment.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a constant temperature and humidity chamber with a visual liquid level monitoring water supply system, including a main body 1 and a water tank mechanism 4;

[0021] The rear of the top of the main body 1 of the equipment is provided with a placement slot 2, and the water tank mechanism 4 is detachably installed inside the placement slot 2;

[0022] The water tank mechanism 4 includes a device base frame 41 adapted to the contour of the placement slot 2. A transparent plastic water storage tank 42 is fixedly connected to the top of the device base frame 41. A circuit board 43 is installed inside the device base frame 41. A PCB contact 44 is installed on the rear of the upper surface of the circuit board 43. A riser 45 extending into the water storage tank 42 is vertically fixedly connected inside the device base frame 41 and above the PCB contact 44. A slide rod 46 is vertically slidably connected inside the riser 45. A float ball 47 is fixedly connected to the top of the slide rod 46. A buzzer 48 is installed on the circuit board 43.

[0023] When the slider 46 is not under force, its bottom end contacts the PCB contact 44.

[0024] The main body 1 of the device is a constant temperature and humidity chamber, and the water tank structure 4 is detachably installed inside the placement slot 2 opened at its top, and water is supplied to it through the water tank mechanism 4.

[0025] The water tank 42 in the water tank mechanism 4 is made of blue transparent plastic, allowing the internal water level to be directly observed from the outside. The float 47 inside floats on the water surface under the action of buoyancy. The height of the float 47 moves with the horizontal plane, and the position of the sliding rod 46 fixedly connected to its bottom also moves synchronously with the movement of the float 47. When the horizontal plane is lower than a certain level, the bottom of the sliding rod 46 will contact the PCB contact 44 on the circuit board 43 inside the device bottom frame 41, thereby triggering an alarm. The buzzer 48 will then sound to remind the staff that the water level is insufficient, thus preventing problems caused by insufficient water level during the operation of the main body of the equipment 1.

[0026] The top part of the riser 45 is provided with a sealing ring structure to prevent water from flowing into the interior of the device bottom frame 41 through the gap between the riser 45 and the slide bar 46. The circuit board 43 also integrates a signal receiving module, a signal conversion module and a control module. When the PCB contact 44 is triggered, it is received by the signal receiving module, converted by the signal conversion module and sent to the control module, and then the control module controls the buzzer 48 to start.

[0027] The water tank 42 in the water tank mechanism 4 has an inlet at the front end, and a cap is installed on the inlet by means of a threaded connection.

[0028] Multiple positioning protrusions 3 are fixedly connected to the bottom of the placement slot 2, and multiple slots 49 are formed on the bottom of the device frame 41, which correspond to and fit the multiple positioning protrusions 3 respectively.

[0029] Multiple positioning protrusions 3 and slots 49 can achieve stable positioning, improve the stability of the water tank mechanism 4 when it is placed on top of the main body 1, and prevent the water tank mechanism 4 from falling and being damaged.

[0030] The top of the water tank 42 is fixedly connected with multiple lifting handles 411, and the lower part of the front surface of the water tank 42 is provided with a limit scale mark 412.

[0031] The lifting handle 411 makes it easy to remove the water tank mechanism 4 from the top of the main body 1 for water addition, and the limiting scale 412 clearly indicates the position of the minimum water volume, making it convenient for staff to determine whether water needs to be added.

[0032] A sound outlet 413 is provided on the front surface of the device base frame 41 at the position of the buzzer 48.

[0033] The sound outlet 413 makes it easier for the sound emitted by the buzzer 48 to be transmitted.

[0034] A water pipe connector 410 is connected to one side surface of the water storage tank 42. A vertically arranged pipe groove 5 is opened on one side surface of the equipment body 1. Multiple pipe clamps 6 are fixedly connected evenly at intervals along the length of the pipe groove 5. A water supply pipe 7 is connected to the water inlet of the equipment body 1. The other end of the water supply pipe 7 extends upward through the pipe groove 5 and is connected to the water pipe connector 410.

[0035] The pipe groove 5 and the pipe clamp 6 inside it can fix the water pipe 7, so that it will not be exposed outside the main body of the equipment 1 at will, and prevent the water pipe 7 from detaching from the device due to some special circumstances during the operation of the equipment.

[0036] Multiple support blocks 8 are fixedly connected to the bottom of the main body 1 of the equipment.

[0037] The support block 8 provides support, and its bottom end is equipped with an anti-slip textured structure, which can improve the overall stability of the device.

[0038] During operation, the water tank 42 in the water tank mechanism 4 of the device is made of blue transparent plastic, allowing direct observation of the internal water level from the outside. The float 47 inside floats on the water surface under the action of buoyancy. The height of the float 47 moves with the horizontal plane, and the position of the sliding rod 46 fixedly connected to its bottom also moves synchronously with the movement of the float 47. When the horizontal plane is lower than a certain level, the bottom of the sliding rod 46 will contact the PCB contact 44 on the circuit board 43 inside the bottom frame 41 of the device, thereby triggering an alarm. The buzzer 48 will then sound to remind the staff that the water level is insufficient, thus preventing problems caused by insufficient water level during the operation of the main body of the equipment 1.
