Description

Technical Field

[0001] This utility model relates to the field of drinking water processing technology, specifically to a descaling device for drinking water tanks. Background Technology

[0002] A search revealed Chinese patent number CN202321880588.5, which discloses a tank descaling device, relating to the field of pure water processing technology. The device aims to solve the problem that during the pure water processing, impurities in the water source are removed, resulting in a large amount of scale adhering to the inner wall of the tank, affecting the quality of the pure water in subsequent use. The top surface of the tank is equipped with a support frame, on which a motor is mounted. A rotating shaft is rotatably connected inside the tank, and the shaft is connected to the motor. A descaling mechanism is located on the outer wall of the shaft, and a cleaning mechanism is located on the tank, connected to the descaling mechanism. Through the interaction of a sliding groove, spring, slider, and sliding plate on the support rod, during use, the spring exerts force on the slider within the sliding groove, causing the slider to move outward. Simultaneously, the moving slider pushes the connected sliding plate towards the inner wall of the tank. Subsequently, driven by the motor, the rotating shaft rotates inside the tank, causing friction between the sliding plate and the inner wall of the tank, removing the scale from the inner wall and cleaning the inside of the tank.

[0003] However, the above solution still has its drawbacks. When using a sliding plate to clean the inner wall of the tank, it is impossible to clean the upper and lower surfaces of the inner cavity of the tank, resulting in incomplete cleaning. In addition, in order to clean stubborn dirt inside the tank, cleaning fluid is often injected into the tank by a water pump. However, whether the amount of cleaning fluid is sufficient, i.e. whether it needs to be replenished, is often judged by the work experience of the staff. This often results in the cleaning fluid not being replenished in time, causing the inner wall of the tank to not reach the required level of cleanliness, which leads to a poor user experience.

[0031] A stirring mechanism 140 is installed on the second tank 130. The stirring mechanism 140 is configured to stir the cleaning agent inside the stirring mechanism 140. The stirring mechanism 140 includes a second connecting shaft 141, a stirring blade 142, and a belt drive 143. The second connecting shaft 141 is rotatably mounted on the second tank 130. The stirring blade 142 is fixed on the outer wall of the second connecting shaft 141. The first connecting shaft 122 and the second connecting shaft 141 are connected together by the belt drive 143.

[0032] The cleaning fluid injection mechanism 150 is installed on the second tank 130 and the first tank 110. The cleaning fluid injection mechanism 150 is used to inject cleaning fluid into the first tank 110. The cleaning fluid injection mechanism 150 includes a water pump 151, a first water guide pipe 152 and a second water guide pipe 153. The water pump 151 is fixed on the upper surface of the bracket 181. One end of the first water guide pipe 152 and one end of the second water guide pipe 153 are both installed on the water pump 151.

[0033] The weighing mechanism 180 is installed on the first tank 110 and the second tank 130. The weighing mechanism 180 is set to monitor the amount of cleaning liquid in the second tank 130 in real time. The weighing mechanism 180 includes a bracket 181, a weight sensor 182 and a guide rod 183. The bracket 181 is fixed on the outer wall of the second tank 130. The weight sensor 182 is installed between the bracket 181 and the second tank 130. The lower end of the guide rod 183 is fixed on the upper surface of the bracket 181. The guide rod 183 slides through the second tank 130. It also includes a buzzer 190, which is fixed on the upper surface of the first tank 110. The buzzer 190 and the weight sensor 182 are electrically connected together.

[0034] The working principle and process of this utility model are as follows: In use, a certain amount of cleaning agent and water are injected into the second tank 130. Then, the temperature controller 170 is operated to control the electric heating rod 160 to work. The electric heating rod 160 heats the liquid in the second tank 130, bringing the temperature of the liquid in the second tank 130 to the set value. Then, the motor 121 is operated through the control box. The rotation of the output shaft of the motor 121 drives the first connecting shaft 122 to rotate. The rotation of the first connecting shaft 122 realizes the connection between the belt drive component 143 and the scraper 123. The rotation of the belt drive 143 drives the second connecting shaft 141 to rotate, which in turn drives the stirring blade 142 to rotate. The stirring blade 142 agitates the cleaning agent to obtain a cleaning solution. After a certain period of time, the operator operates the water pump 151 through the control box. The water pump 151 sprays the cleaning solution at a suitable temperature onto the inner wall of the first tank 110 through the nozzle 125. The scraper 123 scrapes the inner wall of the first tank 110. Under the combined action of the scraper 123 and the cleaning solution, the inner wall of the first tank 110 is descaled. During the descaling process, when the weight sensor 182 detects that the amount of cleaning fluid in the second tank 130 has reached the set minimum value, the weight sensor 182 transmits a signal to the buzzer 190. The buzzer 190 then sounds an alarm to remind the operator to replenish the cleaning fluid. The operator pours the prepared cleaning agent and water into the second tank 130. When the weight sensor 182 detects that the amount of cleaning fluid in the second tank 130 has reached the set value, the weight sensor 182 transmits a signal to the buzzer 190, and the buzzer 190 stops working, ensuring the cleaning fluid is replenished. The cleaning of the inner wall of the first tank 110 is achieved by using a single motor 121 to simultaneously rotate the first connecting shaft 122 and the second connecting shaft 141, thus enabling simultaneous cleaning and stirring. The scraper 123 cleans the upper and lower surfaces of the inner cavity of the first tank 110, ensuring a more thorough cleaning. In addition, the weight sensor 182 and the buzzer 190 can replenish the cleaning fluid in the second tank 130 in a timely manner, ensuring that there is no shortage of cleaning fluid and providing users with a better user experience.

[0035] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
