Description

Technical Field

[0001] This utility model relates to the technical field of water heater booster devices, specifically a solar water heater venting booster device. Background Technology

[0002] A solar water heater is a heating device that converts solar energy into heat energy, heating water from a low temperature to a high temperature to meet people's hot water needs in daily life and production. A venting and pressurizing device is a device that combines venting and pressurizing functions, designed to solve the problems of cold water accumulation and low water pressure in the pipes of a solar water heater.

[0003] A typical venting and pressurizing device includes a fully automatic booster pump (which can automatically vent air and impurities), control valves, connecting pipes, and other components. Through the coordinated work of these components, the effects of fully automatic venting and pressurization are achieved. Since scale easily forms in the water inside the water heater during the heating process, and the scale can easily cause blockages in the booster pump after entering through the connecting pipes, it will affect the automatic venting effect of the booster pump. Therefore, a venting and pressurizing device for solar water heaters is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a solar water heater venting and boosting device to solve the problem that scale entering the booster pump will affect its automatic venting effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A solar water heater venting and pressurization device includes a booster pump for pressurization, an mounting block for installing the booster pump, a connector, and a connecting pipe. The bottom of the booster pump is fixedly connected to the mounting block with a hole in the middle for inserting bolts. The top and bottom of the booster pump are both fixedly connected to the connector. A connecting pipe is threaded to one side of the connector. The upper part of the connecting pipe has a cover plate on the front side. A fixing frame with several recesses on its surface is fixedly connected to the rear side of the cover plate. A filter screen for filtering scale is tightly fitted to the top of the fixing frame. Sliding strips are fixedly connected to both sides of the fixing frame.

[0007] Preferably, a plurality of positioning posts are fixedly connected to the bottom of the filter screen, one end of each positioning post is located in the recess of the fixed frame, and magnetic blocks are provided in both the positioning posts and the fixed frame.

[0008] Preferably, a groove is provided on one side of the connecting pipe in the upper part, a fixing plate is fixedly connected in the groove, a sliding rod is slidably connected in the fixing plate, and a spring is provided on the outside of the sliding rod.

[0009] Preferably, a rubber layer with both ends protruding backwards is fixedly connected to the rear side of the cover plate, and the rubber layer is in close contact with the surface of the upper part of the connecting pipe.

[0010] Preferably, a rubber plate is rotatably connected to the top of the rubber layer, a rubber plug is fixedly connected to the rear side of the rubber plate, and a through hole is opened on the front side of the connecting pipe in the upper part, the height of the through hole being greater than the combined height of the fixed frame and the filter screen.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model includes a booster pump, mounting block, connector, connecting pipe, cover plate, fixing frame, and filter screen. One of the connecting pipes is connected to the water pipe of the water heater. When the water heater and booster pump are in use, the filter screen effectively filters scale as water flows through the connecting pipe above the booster pump, preventing it from entering the booster pump and causing blockage. This avoids scale affecting the pump's emptying process. The system also includes a rubber layer, groove, fixing plate, slide rod, spring, rubber plate, rubber plug, and through hole. The rubber plate and rubber layer work together to effectively waterproof the through hole, preventing water from overflowing. Rotating the rubber plate moves the rubber plug away from the connecting pipe, allowing the cover plate to move forward and expose part of the filter screen. Since the height of the through hole is greater than the combined height of the filter screen and fixing frame, it is easy to move the filter screen up and remove it through the through hole. The sliding bar facilitates the movement of the fixing frame, and the positioning post and magnetic block facilitate simple fixing of the filter screen. The removable filter screen makes it easy to replace after prolonged use. Attached Figure Description

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A solar water heater venting and pressurization device includes a booster pump 1 for pressurization, an mounting block 2 for installing the booster pump 1, a connector 3, and a connecting pipe 4. The bottom of the booster pump 1 is fixedly connected to the mounting block 2, which has a hole in the middle for inserting bolts. The top and bottom of the booster pump 1 are both fixedly connected to the connector 3. The connecting pipe 4 is threaded to one side of the connector 3. The upper part of the connecting pipe 4 has a cover plate 5 on the front side. The rear side of the cover plate 5 is fixedly connected to a fixing frame 11 with several recesses on its surface. The top of the fixing frame 11 is tightly fitted with a filter screen 12 for filtering scale. The fixing frames 11 are fixedly connected to both sides of the fixing frame 11. The filter screen 12 prevents scale from easily entering the booster pump 1, thus avoiding scale affecting the automatic venting process of the booster pump 1. The filter screen 12 is removable, making it easy to replace.

[0023] Several positioning posts 13 are fixedly connected to the bottom of the filter screen 12. One end of the positioning post 13 is set in the recess of the fixed frame 11. Both the positioning post 13 and the fixed frame 11 are equipped with magnetic blocks 15 to facilitate the fixation of the filter screen 12. A groove 7 is opened on one side of the upper part connecting pipe 4. A fixed plate 8 is fixedly connected in the groove 7. A sliding rod 9 is slidably connected in the fixed plate 8. A spring 10 is provided on the outside of the sliding rod 9 to facilitate the automatic return of the cover plate 5. A rubber layer 6 with both ends protruding backward is fixedly connected to the rear side of the cover plate 5. The rubber layer 6 and the surface of the upper part connecting pipe 4 are tightly fitted to increase the sealing effect of the cover plate 5. A rubber plate 16 is rotatably connected to the top of the rubber layer 6. A rubber plug 17 is fixedly connected to the rear side of the rubber plate 16. A through hole 18 is opened on the front side of the upper part connecting pipe 4. The height of the through hole 18 is greater than the combined height of the fixed frame 11 and the filter screen 12 to facilitate the removal of the filter screen 12.

[0024] Working Process: When using the solar water heater purging and pressurizing device, firstly, the booster pump 1 is purged to remove air and impurities. Then, the connecting pipe 4 above the booster pump 1 is connected to the water pipe of the water heater, and the connecting pipe 4 below the booster pump 1 is connected to the water pipe of the shower head. During use, water from the water heater flows into the booster pump 1 through the connecting pipe 4 above. Since a filter screen 12 is installed inside this connecting pipe 4, it can filter out limescale. The filtered water is then sprayed out from the shower head after passing through the booster pump 1, achieving a pressurization effect. When the filter screen 12 needs to be replaced after prolonged use, the user drains all the water from the connecting pipe 4, then rotates the rubber plate 16 forward. Since both the rubber plate 16 and the rubber plug 17 are flexible and elastic, the rubber plug 17 is removed from the connecting pipe 4 above. Then, the user moves the cover plate 5 forward, causing the fixing frame 11 and the sliding rod 9 to move forward simultaneously. The sliding strip 14 slides on the inner wall of the connecting pipe 4 above, and the spring 10 is compressed. The fixed frame 11 moves the filter 12 forward simultaneously. Once it reaches the desired position, the user holds the filter 12 by both sides and moves it upward, causing the positioning post 13 to move away from the fixed frame 11 until it is flush with the top of the through hole 18. At this point, the filter 12 can be moved forward and removed. Then, a new filter 12 is inserted into the through hole 18. After it is inserted into the desired position, the user releases the filter 12. Under the influence of gravity, the filter 12 moves downward until the positioning post 13 is inserted into the fixed frame 11. Magnetic attraction is generated between the magnetic blocks 15, which attracts the filter... 12 is fixed, then the cover plate 5 is loosened. Under the action of the spring 10, the cover plate 5 is moved backward until the rubber layer 6 is tightly attached to the upper connecting pipe 4. Then the rubber plate 16 is rotated in the opposite direction until the rubber plug 17 is inserted into the upper connecting pipe 4, completing one replacement of the filter screen 12. The filter screen 12 makes it difficult for scale to enter the booster pump 1, avoiding scale from affecting the automatic emptying process of the booster pump 1. The removable structure of the filter screen 12 makes it easy to replace the filter screen 12.
