Description

Technical Field

[0001] The utility model belongs to the technical field of bimetallic thermometer cleaning devices, and in particular relates to a cleaning device for a bimetallic thermometer. Background Art

[0002] The bimetallic thermometer combines two metals with different linear expansion coefficients and fixes one end. When the temperature changes, the two metals expand differently, causing the pointer to deflect to indicate the temperature.

[0003] At present, after the plug of the bimetallic thermometer fails, a lot of impurities will enter the sleeve of the bimetallic thermometer, thereby affecting the detection accuracy of the bimetallic thermometer. When cleaning the inside of the sleeve, the various components of the bimetallic thermometer need to be disassembled, which makes the cleaning efficiency of the bimetallic thermometer low. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problems and to provide a cleaning device for a bimetallic thermometer.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a cleaning device for a bimetallic thermometer, comprising:

[0006] A metal enclosure, which is a coverless box body, the metal enclosure is filled with a cleaning liquid, and a semiconductor refrigerator is installed on the outer wall of the metal enclosure;

[0007] A protective tube, the lower end of which is fixedly connected to the bottom wall in the metal enclosure, and the upper end of which extends to the top of the metal enclosure;

[0008] A roller brush is sleeved on the protection tube, and a floating piece is arranged at the lower end of the roller brush.

[0009] As a further description of the above technical solution:

[0010] The protection tube is a round tube, the interior of the roller brush is a round hole, and the inner wall of the protection tube fits the inner wall of the roller brush.

[0011] As a further description of the above technical solution:

[0012] The length of the protection tube is greater than the length of the roller brush.

[0013] As a further description of the above technical solution:

[0014] The floating member is in a circular ring shape, and the outer diameter of the floating member is greater than the outer diameter of the roller brush.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] In the utility model, the cleaning liquid in the metal enclosure is cooled by a semiconductor refrigerator, thereby reducing the temperature in the protective tube. When cleaning the bimetallic thermometer, the plug of the bimetallic thermometer is removed, and the sleeve of the bimetallic thermometer only needs to be put on the roller brush. The spiral temperature sensing device extends into the protective tube and shrinks, pushing the roller brush to slide downward along the protective tube. After dipping in the cleaning liquid, the roller brush is released. The floating part is acted upon by the buoyancy and drives the roller brush to slide upward along the protective tube. The roller brush can clean the inner wall of the sleeve. There is no need to disassemble the various components of the bimetallic thermometer, so that the cleaning efficiency of the bimetallic thermometer is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 The utility model provides a technical solution: a cleaning device for a bimetallic thermometer, comprising:

[0025] A metal enclosure 1 is a box body without a cover, the metal enclosure 1 is filled with a cleaning liquid, and a semiconductor refrigerator 2 is installed on the outer wall of the metal enclosure 1;

[0026] A protection tube 3, the lower end of which is fixedly connected to the bottom wall inside the metal enclosure 1, and the upper end of the protection tube 3 extends to the top of the metal enclosure 1;

[0027] A roller brush 4 is sleeved on the protection tube 3, and a floating member 5 is provided at the lower end of the roller brush 4;

[0028] The protection tube 3 is a round tube, the interior of the roller brush 4 is a round hole, and the inner wall of the protection tube 3 fits the inner wall of the roller brush 4, ensuring that the roller brush 4 can slide along the protection tube 3 and rotate along the protection tube 3, thereby facilitating rapid and multi-directional cleaning of the inner wall of the bimetallic thermometer sleeve;

[0029] The length of the protection tube 3 is greater than the length of the roller brush 4, providing a sufficiently large activity space for the roller brush 4 to slide;

[0030] The floating member 5 is in a circular ring shape, and the outer diameter of the floating member 5 is greater than the outer diameter of the rolling brush 4 , and has a stopper effect to prevent the floating member 5 from entering the sleeve of the bimetallic thermometer.

[0031] Working principle: First, the semiconductor refrigerator 2 cools the cleaning liquid in the metal enclosure 1, thereby reducing the temperature in the protective tube 3. Secondly, when cleaning the bimetallic thermometer, remove the plug of the bimetallic thermometer, and only need to put the sleeve of the bimetallic thermometer on the roller brush 4. The spiral temperature sensing device of the bimetallic thermometer extends into the protective tube 3 and shrinks, so that the spiral temperature sensing device is not damaged when the sleeve of the bimetallic thermometer is cleaned. Finally, push the roller brush 4 to slide downward along the protective tube 3, and let go after dipping in the cleaning liquid. The floating part 5 is driven by the buoyancy to slide the roller brush 4 upward along the protective tube 3, and the roller brush 4 can clean the inner wall of the sleeve. You can also hold the floating part 5 and rotate it, so that the roller brush 4 rotates along the protective tube 3, which is convenient for the quick and multi-directional cleaning of the inner wall of the sleeve of the bimetallic thermometer. There is no need to disassemble the various components of the bimetallic thermometer, so that the cleaning efficiency of the bimetallic thermometer is high.
