Description

Technical Field

[0001] This utility model relates to the technical field of water bath pot accessories, specifically a water level indicator device for a water bath pot. Background Technology

[0002] Water baths are mainly used in laboratories for distillation, drying, concentration, and warm soaking of chemicals or biological products. They can also be used for constant temperature heating and other temperature tests. They are essential tools for biology, genetics, virology, aquaculture, environmental protection, medicine, health, laboratories, analytical laboratories, and educational research. However, some existing water baths do not have water level indicators or have complex indicator structures, which can easily lead to the water boiling dry during experiments, damaging the equipment, causing inconvenience in maintenance, and high maintenance and expansion costs.

[0003] The utility model patent with publication number CN204485898U discloses a water level indicator for a water bath. It uses a transparent curved tube and has scale markings to indicate the water level, which can conveniently monitor the water depth and allow for timely addition of water to the water bath.

[0004] The current technical solution has at least the following drawbacks: both the top and bottom of the transparent bend are open structures, making it easy for scale and other impurities from the water bath and dust from the outside air to enter the bend and difficult to clean, which also affects the reading. Therefore, we propose a water bath level indicator device. Utility Model Content

[0005] The purpose of this invention is to provide a water level indicator for a water bath. By fitting a lower rubber sleeve and an upper rubber sleeve at the bottom and top of a glass bend, respectively, and installing filter cotton blocks and filter cotton sheets, the water entering the glass bend can be filtered, preventing scale or impurities from entering the glass bend. Meanwhile, dust and other impurities in the air are blocked by the filter cotton sheets, preventing them from entering the glass bend from the outside, ensuring that the inside of the glass bend is clean without affecting normal readings, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water bath level indicator device, comprising a water bath and a glass bend, wherein the glass bend is vertically positioned at the front end of the water bath, and the bottom of the glass bend is bent backward and connected to the interior of the water bath; a lower rubber sleeve is fitted and fixed to the end of the glass bend inside the water bath, a filter cotton block is inserted and fixed inside the glass bend on the inner side of the lower rubber sleeve, and a lower opening is provided on the surface of the lower rubber sleeve; an upper rubber sleeve is fitted and fixed to the top of the glass bend, a filter cotton sheet is abutted and fixed between the inner side of the upper rubber sleeve and the top of the glass bend, and an upper opening is provided on the surface of the upper rubber sleeve.

[0007] By adopting the above technical solution, when water is added to the water bath, it will enter the glass bend tube, maintaining the same water level as the water bath so that the reading can be made through the scale. The filter cotton sheet fixed to the top by the upper rubber sleeve prevents impurities and dust in the air from entering the glass bend tube, while the filter cotton block fixed to the bottom by the lower rubber sleeve prevents scale and impurities in the water from entering the glass bend tube.

[0008] Optionally, the outer surface of the glass bend is provided with scale lines, which are evenly distributed on the outer surface of the glass bend.

[0009] By adopting the above technical solution, the water level in the glass bend can be read more accurately through the scale lines, thus allowing the water level in the water bath to be read.

[0010] Optionally, a colored float is placed in the glass bend, and the float is located in the vertical part of the bend.

[0011] By adopting the above technical solution, the colored float can be observed more clearly, making it easier to read the value.

[0012] Optionally, an annular ring is fixed to the inner wall of the glass bend below the float, and the inner diameter of the ring is smaller than the diameter of the float.

[0013] By adopting the above technical solution, the ring can limit the height of the float's descent, preventing the float from getting stuck in the horizontal part of the glass bend and unable to rise again after the water in the water bath is drained.

[0014] Optionally, a baffle is fixed in the glass bend on the side of the filter cotton block, and the baffle limits the depth to which the filter cotton block is inserted into the glass bend.

[0015] Optionally, a filter screen is fixed in the lower inlet for filtering water in the water bath.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] 1. The technical solution of this application is to install a lower rubber sleeve and an upper rubber sleeve at the bottom and top of the glass bend tube respectively, and to install filter cotton blocks and filter cotton sheets. This can filter the water entering the glass bend tube, preventing scale or impurities from entering the glass bend tube. Meanwhile, dust and other impurities in the air are blocked by the filter cotton sheets, preventing them from entering the glass bend tube from the outside, thus ensuring that the inside of the glass bend tube is clean and does not affect normal readings.

[0018] 2. The technical solution of this application has a colored float installed in the glass bend tube, which can rise with the water level and provide a clearer reading effect. Attached Figure Description

[0025] Please see Figure 1-4 This utility model provides a technical solution: a water bath level indicator device, including a water bath 1 and a glass bend 2. The structure of the water bath 1 is no different from other water baths 1 in the prior art, and the basic mechanism and working principle are all in the prior art, so it will not be described further.

[0026] The glass bend 2 is placed vertically at the front end of the water bath 1. The bottom of the glass bend 2 is bent backward and connected to the inside of the water bath 1. When the water bath 1 is in use, the water inside it can enter the glass bend 2 from below. Due to the principle of communicating vessels, the water level in the glass bend 2 will be the same as the water level in the water bath 1. Therefore, by observing the water level in the glass bend 2, the water level in the water bath 1 can be directly determined.

[0027] The outer surface of the glass bend 2 is provided with scale lines 21, which are evenly distributed on the outer surface of the glass bend 2. The water level in the glass bend 2 can also be read through the scale lines 21, so as to obtain a more accurate water level. In addition, a colored float 26 is placed in the glass bend 2. The float 26 is located in the vertical part of the bend 2 and floats above the water surface in the glass bend 2. The colored float 26 is easier to observe and read in conjunction with the scale lines 21. An annular ring 25 is fixed to the inner wall of the glass bend 2 below the float 26. The inner diameter of the ring 25 is smaller than the diameter of the float 26. When the water in the water bath 1 is drained, the ring 25 restricts the descent height of the float 26 to prevent the float 26 from falling into the horizontal part of the glass bend 2 and getting stuck. It can rise normally when the water level rises in subsequent use.

[0028] A lower rubber sleeve 24 is fixedly fitted to the end of the glass bend 2 inside the water bath 1. A filter cotton block 27 is fixedly inserted into the glass bend 2 inside the lower rubber sleeve 24. A baffle 28 is fixed in the glass bend 2 on the side of the filter cotton block 27. The baffle 28 restricts the depth of the filter cotton block 27 inserted into the glass bend 2. A lower opening 241 is opened on the surface of the lower rubber sleeve 24. At the same time, a filter screen 242 is fixed in the lower opening 241. The water in the water bath 1 will be filtered through the filter screen 242 and the filter cotton block 27 before entering the glass bend 2. Scale and other impurities in the water will not enter the glass bend 2.

[0029] The top of the glass bend 2 is fitted with an upper rubber sleeve 22. A filter cotton sheet 23 is fixed between the inner side of the upper rubber sleeve 22 and the top of the glass bend 2. The surface of the upper rubber sleeve 22 is provided with an upper opening 221. The air pressure inside the glass bend 2 is balanced through the upper opening 221 on the surface of the upper rubber sleeve 22. The filter cotton sheet 23 can prevent dust and other impurities in the air from entering the glass bend 2.

[0030] During use, after water is added to the water bath 1, the water in the water bath 1 will be filtered through the filter screen 242 in the lower opening 241 and pass through the lower rubber sleeve 24. Before entering the glass bend tube 2, it will also be filtered by the filter cotton block 27 to prevent scale and other impurities in the water bath 1 from entering the glass bend tube 2. Due to the principle of communicating vessels, the water level in the glass bend tube 2 is the same as the water level in the water bath 1, and the glass bend tube 2 will cause the float 26 to float. By observing the scale line 21 where the float 26 is located, the water level in the water bath 1 can be easily and quickly read. The glass bend tube 2 is connected to the outside through the upper opening 221 of the upper rubber sleeve 22 to balance the air pressure. The filter cotton sheet 23 can prevent external dust and other impurities from entering the glass bend tube 2. After use, both the upper rubber sleeve 22 and the lower rubber sleeve 24 can be easily removed, so as to facilitate the replacement of the filter cotton sheet 23 and the filter cotton block 27.
