Description

Technical Field

[0001] The utility model relates to the technical field of constant temperature water pots, in particular to a water adding mechanism for a constant temperature water pot. Background Art

[0002] A water bath pot is mainly used for distillation, drying, concentration, and soaking of chemical drugs or biological products in a laboratory, and can also be used for constant temperature heating and other temperature tests. It is an essential tool for biology, genetics, virology, aquaculture, environmental protection, medicine, health, laboratories, analysis rooms, and education and scientific research.

[0003] After a constant temperature water pot is used for a period of time, due to the high water temperature, the water in the constant temperature water pot will evaporate, resulting in a decrease in the water level. When the water level is too low, the water bath heating effect will decline. In the prior art, manual water addition is generally used, which not only easily causes water to splash and scald the staff, but also increases the labor intensity of the staff and has low safety. Therefore, we have developed a water adding mechanism for a constant temperature water pot. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water adding mechanism for a constant temperature water pot, which can automatically inject water when the water in the water pot is insufficient, has a high degree of automation, good structural reliability, improves safety, and reduces the labor intensity of the staff, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A water adding mechanism for a constant temperature water pot includes a water pot body. A heating device and a temperature sensor are fixedly arranged inside the water pot body. An injection port is arranged at the upper end of the water pot body. A shell is fixedly arranged on the upper side of the inner wall of the water pot body. A through hole is arranged on one side of the shell close to the injection port. A water inlet pipe is fixedly communicated with the side of the shell interior far from the injection port. A water outlet is arranged at the bottom of the shell. A rectangular ring is arranged on the upper side inside the water pot body. One side of the rectangular ring close to the shell is hinged to the shell through a rotating connecting piece. A plurality of floating balls are fixedly arranged on the side of the rectangular ring far from the shell. A sealing mechanism is arranged between the rotating connecting piece and the through hole.

[0007] Preferably, the sealing mechanism includes a sliding rod. The sliding rod is slidably arranged in the through hole. Both ends of the sliding rod extend to the outside of the through hole. A sealing block is fixedly arranged at one end of the sliding rod located inside the shell. The sealing block corresponds to the position of the water inlet pipe. A push plate is fixedly arranged at the end of the sliding rod located outside the shell. A top block is arranged on the other side of the push plate. The lower end of the top block is fixedly connected to the upper end of the rotating connecting piece. A spring is movably sleeved on the rod wall of the sliding rod between the push plate and the through hole.

[0008] Preferably, the sealing block is arranged in a frustum shape.

[0009] Preferably, the spring is always in a compressed state.

[0010] Preferably, the sealing block is a high-temperature resistant rubber block.

[0011] Preferably, a pot lid is provided in the water injection port, and a pulling block is fixedly provided at the top of the pot lid.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] For the water adding mechanism of the constant temperature water pot, by providing a water pot body, a pot lid, a water inlet pipe, a heating device, a rectangular ring, a floating ball, a temperature sensor, a housing, a sealing block, a sliding rod, a spring, a push plate, a top block, a rotating connecting piece, and a water outlet, the water inlet pipe is connected to the tap water pipe, and the valve is opened. When the water level in the water pot body is relatively high, due to the buoyancy of water, the floating ball is pushed upward. The floating ball drives the top block on the rotating connecting piece to push the push plate through the rectangular ring. While the push plate presses the spring, it drives the sealing block at the other end of the sliding rod to tightly abut against the end of the water inlet pipe. When the water level is relatively low, the floating ball descends, and the rectangular ring drives the top block to no longer push the push plate. At this time, the spring pushes the push plate and makes the sliding rod drive the sealing block to no longer seal the water inlet pipe. At this time, the water in the tap water pipe is injected, which can automatically inject water when the water in the water pot is insufficient, with a high degree of automation, good structural reliability, reduced labor intensity of workers, and improved safety.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 3 , the present utility model provides a technical solution:

[0020] A water adding mechanism for a constant temperature water pot, including a water pot body 1, a heating device 4 and a temperature sensor 7 are fixedly arranged inside the water pot body 1, a water injection port is arranged at the upper end of the water pot body 1, a housing 8 is fixedly arranged on the upper side of the inner wall of the water pot body 1, a through hole is arranged on one side of the housing 8 close to the water injection port, a water inlet pipe 3 is fixedly communicated with the side of the housing 8 far from the water injection port, a water outlet 15 is arranged at the bottom of the housing 8, a rectangular ring 5 is arranged on the upper side inside the water pot body 1, one side of the rectangular ring 5 close to the housing 8 is hinged to the housing 8 through a rotating connecting piece 14, a plurality of floating balls 6 are fixedly arranged on the side of the rectangular ring 5 far from the housing 8, and a sealing mechanism is arranged between the rotating connecting piece 14 and the through hole.

[0021] The sealing mechanism includes a sliding rod 10, the sliding rod 10 is slidably arranged in the through hole, both ends of the sliding rod 10 extend to the outside of the through hole, a sealing block 9 is fixedly arranged at one end of the sliding rod 10 located inside the housing 8, the sealing block 9 corresponds to the position of the water inlet pipe 3, a push plate 12 is fixedly arranged at one end of the sliding rod 10 located outside the housing 8, a top block 13 is arranged on the other side of the push plate 12, the lower end of the top block 13 is fixedly connected to the upper end of the rotating connecting piece 14, and a spring 11 is movably sleeved on the rod wall of the sliding rod 10 between the push plate 12 and the through hole.

[0022] The sealing block 9 is arranged in a frustum shape, which can improve the sealing effect.

[0023] The spring 11 is always in a compressed state, and the spring 11 can drive the sealing block 9 to reset.

[0024] The sealing block 9 is a high-temperature resistant rubber block, and the sealing block 9 has good high-temperature resistance and is not easy to deform at high temperatures.

[0025] A pot cover 2 is arranged in the water injection port, and a pulling block is fixedly arranged at the top of the pot cover 2.

[0026] During use, the water inlet pipe 3 is connected to the tap water pipe and the valve is opened.
