Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically to a purified water purification equipment that prevents backflow of contaminants. Background Technology

[0002] Pure water is an inorganic compound with the chemical formula [chemical formula missing]. It is a liquid with a certain structure. Although it is not rigid, its arrangement is much more regular than that of gaseous water molecules. In liquid water, water molecules do not exist as individual molecules, but rather as clusters of water molecules linked by hydrogen bonds. Therefore, the orientation and movement of water molecules are significantly affected by other water molecules around them. There is no definitive structural model for water. The three main models that are widely accepted are the mixed type, the interstitial type, and the continuous structure model.

[0003] In existing technologies, water purification equipment uses pasteurization to initially sterilize and disinfect purified water. Then, the purified water stored in the tank is squeezed out and sent to the next processing step by the up-and-down movement of a piston. However, the traditional piston-squeezed purified water is slow, which may cause the purified water to stay in the production tank for too long, increasing the chance of contact with air and increasing the risk of microbial recontamination. If recontamination occurs, it will not only affect the quality of the purified water, but may also require sterilization and disinfection again, increasing costs and time. Slow flow may also cause the sedimentation of suspended solids in the water, affecting the purity of the water. Utility Model Content

[0029] 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.

[0030] Please see Figure 1 - Figure 6 This utility model provides a technical solution for a purified water production device that prevents backflow and contamination:

[0031] In the embodiments of this utility model, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 The device includes a tank body 1, with an installation shell 2 installed at the top center of the tank body 1. A rapid drainage assembly 3 is installed inside the installation shell 2. The rapid drainage assembly 3 includes a motor 301 installed on the inner wall of the installation shell 2. One end of the motor 301 is connected to a rotating shaft 302. One end of the rotating shaft 302 is fixedly connected to a stop block 303. The outer wall of the rotating shaft 302 is also connected to a first connecting rod 304. One side of the outer wall of the first connecting rod 304 is connected to an abutment block 305. The end of the first connecting rod 304 away from the rotating shaft 302 is connected to a second connecting rod 306. The end of the second connecting rod 306 away from the first connecting rod 304 is connected to a third connecting rod 307. A sleeve 308 is fitted on the outer wall of the third connecting rod 307. A spring 309 is connected to the inner wall of the sleeve 308. The bottom end of the spring 309 is connected to a pressing sliding block 310. The bottom end of the pressing sliding block 310 is connected to a push rod 4. A piston 5 is installed at the bottom end of the push rod 4.

[0032] It should be noted that the motor 301 is fixedly connected to the inner wall of the mounting housing 2. This fixed connection ensures that the motor 301 can stably transmit power during operation. When the motor 301 starts, the rotational power is directly transmitted to the rotating shaft 302. At the same time, one end of the rotating shaft 302 is also fixedly connected to the inner wall of the stop block 303, so that the stop block 303 can rotate synchronously with the rotating shaft 302. The length of the abutment block 305 installed on the outer wall of the first connecting rod 304 is adapted to the stop block 303. When the stop block 303 rotates, it will abut against the abutment block 305, which can cause the second connecting rod 306 to lift up according to the rotation angle of the abutment block 305. When the stop block 303 rotates to a certain angle, the abutment block 305 will no longer abut against the stop block 303 and will fall down, pushing the third connecting rod 307 to drive the push rod 4 and piston 5 to fall down at the same time. At the same time as falling, the power stored in the spring 309 when the third connecting rod 307 is lifted and the weight of the piston 5 itself help to quickly discharge the purified water.

[0033] See Figure 5 A water outlet pipe 6 is connected to the outer wall of the tank body 1 near the bottom. A bracket 7 is connected to the outer wall of the middle part of the bottom of the tank body 1. The inner walls of the water outlet pipe 6 and the water inlet pipe 10 are both connected to the bracket 7. A valve 8 is connected to the middle of each bracket 7.

[0034] It should be noted that when piston 5 moves upward, the water pressure inside tank 1 increases, pushing the valve 8 on the inner wall of inlet pipe 10 to open, allowing purified water to enter. When piston 5 moves downward, a negative pressure is formed inside tank 1, and the valve 8 inside outlet pipe 6 opens, allowing purified water to flow out.

[0035] See Figure 6 A quick-release assembly 9 is installed on one side of the water inlet pipe 10. The quick-release assembly 9 includes an installation plate 901 installed on the outer wall of one side of the water inlet pipe 10. One end of the installation plate 901 is connected to a first fixing block 902. The top end of the first fixing block 902 is connected to a movable rod 903. Both ends of the movable rod 903 are rotatably connected to a fourth connecting rod 904. A second fixing block 905 is installed at the end of the fourth connecting rod 904 away from the movable rod 903. The bottom end of the second fixing block 905 is connected to a filter screen 906.

[0036] It should be noted that the quick-release assembly 9 is installed on the outer wall of one side of the water inlet pipe 10 via the mounting plate 901. The fixed connection between the mounting plate 901 and the water inlet pipe 10 ensures the stability of the quick-release assembly 9 during operation. The top of the first fixing block 902 is rotatably connected to one end of the movable rod 903 and is rotatably connected to the second fixing block 905 via the fourth connecting rod 904. Pulling the control rod installed on the outer wall of one end of the movable rod 903 allows the filter screen 906 to be quickly pulled out, so as to quickly replace the reverse osmosis membrane and ensure the safety of the equipment during use.

[0037] Working principle: The starting motor 301 drives the rotating shaft 302, which in turn drives the stop block 303 to rotate synchronously. The rotation of the stop block 303 further drives the first connecting rod 304, causing the contact block 305 to abut against the stop block 303 and rotate around the rotating shaft 302. When the first connecting rod 304 rotates, the rotation is transmitted through the second connecting rod 306 and the third connecting rod 307 to the spring 309 and the pressing sliding block 310 on the inner wall of the sleeve 308. Because the bottom end of the sleeve 308 is fixedly connected to the top end of the tank 1, the rotation is transmitted through the third connecting rod 306 and the spring 309 on the inner wall of the sleeve 308 to the pressing sliding block 310. After the lever 307 lifts the squeezing sliding block 310, it will contract according to the characteristics of the spring 309. When the abutment block 305 rotates to a certain extent, it will no longer abut against the stop block 303 and will fall, causing the third connecting rod 307 to fall at the same time. This causes the push rod 4 to push the piston 5 to squeeze and discharge the purified water inside the tank 1. Before the piston 5 is lifted to the falling threshold, the motor 301 will stop operating and the purified water will be pasteurized by the heating component on the inner wall of the tank 1. After the heating is completed, the motor 301 will start and cause the piston 5 to fall.
