Description

Technical Field

[0002] The field of smart toilet technology emerged against the backdrop of accelerated urbanization, increased population density, and the exposure of numerous shortcomings in traditional public toilet management. It integrates IoT, big data, artificial intelligence, and cloud computing technologies to monitor human activities, facility and equipment operation, ambient air changes, and business processes within public toilets in real time and effectively. Based on data, it optimizes management and services to meet the high demands of modern people for public health facilities. By incorporating the high-performance sealing structure of vacuum negative pressure equipment, the field of smart toilet technology has achieved significant improvements in the efficiency of public toilet systems in terms of efficient suction, low energy consumption, and adaptability to extreme environments. At the same time, relying on IoT and intelligent control technologies, it achieves closed-loop management of real-time monitoring of sealing status, fault early warning, and adaptive adjustment.

[0003] When it is necessary to ensure long-term stable suction and prevent gas leakage in the vacuum negative pressure system of a smart toilet, a special sealing structure is required to ensure reliable operation of the equipment. A sealing structure for vacuum negative pressure equipment, by using high pressure-resistant and corrosion-resistant sealing materials and precision-machined sealing surface design, effectively solves the leakage problem in a vacuum environment, ensures long-term stable operation of the equipment, reduces energy consumption and extends maintenance cycle. However, most existing sealing structures are positioned by manual calibration, which is prone to deviation, resulting in low positioning accuracy, easy damage to the seal, and reduced practicality.

[0004] To overcome the above shortcomings, this utility model provides a sealing structure for a cold-resistant vacuum negative pressure device, aiming to improve the problems of existing technologies where the sealing structure cannot be guided and positioned, resulting in low positioning accuracy and easy damage to the seal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sealing structure for a cold-resistant vacuum negative pressure device, comprising a base, a flange 1 fixedly connected to the right side of the base, a plurality of positioning holes 1 opened on the inner wall of the flange 1, a positioning column 1 slidably connected to the inner wall of the positioning hole 1, a flange 2 fixedly connected to the right end of the positioning column 1, a positioning hole 2 opened on the top of the outer wall of the positioning column 1, a positioning column 2 slidably connected to the inner wall of the positioning hole 2, a rotating plate 2 rotatably connected to the top of the inner wall of the positioning column 2, a pressing plate fixedly connected to the right side of the rotating plate 2, a rotating block fixedly connected to the bottom of the pressing plate, a rotating shaft rotatably connected to the inner wall of the rotating block, a vertical plate fixedly connected to the rear end of the rotating shaft, a concave plate 3 fixedly connected to the bottom of the vertical plate, a spring column 2 fixedly connected to the top of the concave plate 3, and a radial support mechanism fixedly connected to the inner wall of the base, the radial support mechanism being used to compensate for shrinkage difference.

[0006] As a further description of the above technical solution:

[0007] The radial support mechanism includes a connecting plate, a support ring fixedly connected to the rear side of the connecting plate, support blocks fixedly connected to the top left and right sides of the support ring, a rotating plate one fixedly connected to the right side of the support block, a concave plate one rotatably connected to the outer wall of the rotating plate one, a connecting column fixedly connected to the right side of the concave plate one, a concave plate two fixedly connected to the right end of the connecting column, a support plate rotatably connected to the right side of the inner wall of the concave plate two, and a spring column one fixedly connected to the bottom of the connecting column.

[0008] As a further description of the above technical solution:

[0009] A connecting ring is fixedly connected to the left side of the seat, and a warning label is fixedly connected to the top of the outer wall of the seat.

[0010] As a further description of the above technical solution:

[0011] A handle is fixedly connected to the rear side of the seat, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0012] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, firstly, the positioning pin one is aligned with the flange one and inserted. Then, the top right side of the pressing plate is pressed to hold the spring pin two, thereby driving the positioning pin two to move upward. Then, the pressing plate is released, so that the positioning pin two is inserted into the positioning hole two, thereby achieving the beneficial effect of guiding and positioning the sealing structure. It is not easy to deviate, improving the positioning accuracy, improving the sealing performance, and improving the practicality.

[0022] 2. In this utility model, when the temperature drops, the sealing structure tends to shrink inward, which will compress the support plate. The support plate will drive the two concave plates on the left and right sides to rotate, thereby dispersing the shrinkage force. Then it will compress the spring column one, which will resist this shrinkage force, thus playing a beneficial role in elastically compensating for low-temperature deformation, filling the sealing gap, improving cold resistance, and improving practicality.

[0031] 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.

[0032] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 This utility model provides an embodiment of a sealing structure for a high-altitude cold-resistant vacuum negative pressure device, comprising a base 1, a flange 3 fixedly connected to the right side of the base 1, a plurality of positioning holes 4 opened on the inner wall of the flange 3, a positioning column 5 slidably connected to the inner wall of the positioning hole 4, a flange 6 fixedly connected to the right end of the positioning column 5, a positioning hole 7 opened on the top of the outer wall of the positioning column 5, a positioning column 14 slidably connected to the inner wall of the positioning hole 7, a rotating plate 13 rotatably connected to the top of the inner wall of the positioning column 14, a pressing plate 12 fixedly connected to the right side of the rotating plate 13, a rotating block 11 fixedly connected to the bottom of the pressing plate 12, a rotating shaft 10 rotatably connected to the inner wall of the rotating block 11, a vertical plate 9 fixedly connected to the rear end of the rotating shaft 10, a concave plate 8 fixedly connected to the bottom of the vertical plate 9, a spring column 15 fixedly connected to the top of the concave plate 8, and a radial support mechanism 2 fixedly connected to the inner wall of the base 1, the radial support mechanism 2 being used to compensate for shrinkage difference;

[0033] Specifically, flange 3 is fixedly connected to the right side of base 1 and is a component connecting other parts of the equipment. Multiple positioning holes 4 are evenly distributed around the circumference of flange 3 on its inner wall. Flange 6 is connected to flange 3 via positioning pin 5. The right end of positioning pin 5 is fixedly connected to flange 6, and the left end is slidably connected within the positioning hole 4. Positioning pin 5 serves as a positioning component connecting flange 3 and flange 6. A positioning hole 7 is formed on the top of its outer wall, and positioning pin 14 is slidably connected within the positioning hole 7, further positioning and restricting the movement direction of flange 6. The inner top of the positioning post 14 is rotatably connected to a rotating plate 13. This rotatable connection allows the rotating plate 13 to rotate freely within a certain angle range. A pressing plate 12 is fixedly connected to the right side of the rotating plate 13, and a vertical plate 9 is fixedly connected to the rear end of the rotating shaft 10. The vertical plate 9 serves to support and fix the rotating shaft 10. When the pressing plate 12 is pressed by an external force, the spring post 15 will be compressed, producing elastic deformation and storing elastic potential energy. When the external force disappears, the spring post 15 will release the elastic potential energy, pushing the pressing plate 12 back to its original position, realizing automatic reset and continuous pressing of the sealing structure, and ensuring the reliability of the seal.

[0034] Please see the appendix Figure 1 Appendix Figure 5 and attached Figure 6 The radial support mechanism 2 includes a connecting plate 201. A support ring 202 is fixedly connected to the rear side of the connecting plate 201. Support blocks 203 are fixedly connected to the top left and right sides of the support ring 202. A rotating plate 204 is fixedly connected to the right side of the support block 203. A concave plate 205 is rotatably connected to the outer wall of the rotating plate 204. A connecting column 206 is fixedly connected to the right side of the concave plate 205. A concave plate 207 is fixedly connected to the right end of the connecting column 206. A support plate 209 is rotatably connected to the right side of the inner wall of the concave plate 207. A spring column 208 is fixedly connected to the bottom of the connecting column 206.

[0035] Specifically, the connecting plate 201 serves a connecting function. A support ring 202 is fixedly connected to the rear side of the connecting plate 201, providing an installation base for subsequent components. Support blocks 203 are fixedly connected to the top left and right sides of the support ring 202. A rotating plate 204 is fixedly connected to the right side of the support block 203. A concave plate 205 is rotatably connected to the outer wall of the rotating plate 204, ensuring both rotational flexibility and preventing wobbling due to excessive gaps. A connecting column 206 is fixedly connected to the right side of the concave plate 205. A concave plate 207 is fixedly connected to the right end of the connecting column 206. A support plate 209 is rotatably connected to the right side of the inner wall of the concave plate 207. A spring column 208 is fixedly connected to the bottom of the connecting column 206. During normal operation of the equipment, the spring column 208 is in its natural state, providing a certain preload. When the equipment deforms due to low-temperature contraction, the spring column 208 is compressed, producing elastic deformation, thereby resisting the contraction force and playing a role in elastic compensation.

[0036] Please see the appendix Figure 1 Appendix Figure 4 and attached Figure 5 A connecting ring 16 is fixedly connected to the left side of the seat body 1. A warning label 17 is fixedly connected to the top of the outer wall of the seat body 1. A handle 20 is fixedly connected to the rear side of the seat body 1. An anti-slip sleeve 21 is fixedly connected to the outer wall of the handle 20. Multiple threaded holes 22 are opened near the edge of the inner wall of the flange 3. Threaded posts 23 are threadedly connected to the inner wall of the threaded holes 22.

[0037] Specifically, the connecting ring 16 serves as a connector, the warning label 17 serves as a warning, the handle 20 is used to move the seat 1, the anti-slip sleeve 21 serves as an anti-slip, the threaded hole 22 is used to fix the threaded post 23, and the threaded post 23 is used to fix flange 1 3 and flange 2 6.

[0038] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 A washer 24 is slidably connected to the outer wall of the threaded column 23, a nut 25 is threadedly connected to the right end of the outer wall of the threaded column 23, a nameplate 18 is fixedly connected to the front side of the seat body 1, a thermometer 19 is fixedly connected to the front side of the seat body 1 near the edge, the inner wall of the concave plate 3 8 is slidably connected to the outer wall of the positioning column 2 14, and the bottom of the pressing plate 12 is fixedly connected to the top of the spring column 2 15.

[0039] Specifically, washer 24 is used to improve sealing, nut 25 is used to fix threaded post 23, nameplate 18 is used to display parameters, thermometer 19 is used to display temperature, concave plate 3 8 restricts the position of positioning post 2 14, and pressing plate 12 can press spring post 2 15 downward.

[0040] Working principle: First, align the positioning pin 5 with the flange 3 and insert it, so that the flange 3 and the flange 6 fit together. Then, press the top right side of the pressing plate 12 to move it downward and press the spring pin 15. The pressing plate 12 drives the rotating block 11 to move. The rotating block 11 rotates around the rotating shaft 10. The upright plate 9 provides support, thereby driving the rotating plate 13 to move. While the rotating plate 13 moves, it rotates on the top of the inner wall of the positioning pin 14, thereby driving the positioning pin 14 to move upward. Then, release the pressing plate 12. Due to the action of the spring pin 15, the pressing plate 12 returns to its original position, so that the positioning pin 14 is inserted into the positioning hole 7, fixing the positioning pin 5. This plays a role in guiding and positioning the sealing structure, making it less prone to displacement, improving positioning accuracy, improving sealing performance, and improving practicality.

[0041] When the temperature drops, due to thermal expansion and contraction, the sealing structure tends to shrink inward, which puts pressure on the support plate 209. The support plate 209 then drives the concave plates 207 on both sides to rotate. The concave plates 207 drive the connecting column 206 to move, and the connecting column 206 drives the concave plate 205 to move. The concave plate 205 rotates on the outer wall of the rotating plate 204. The support block 203 supports the rotating plate 204, thereby dispersing the force of contraction. Then, it will compress the spring column 208. Due to the action of the spring column 208 itself, it will resist this contraction force, thus playing a role in elastic compensation for low-temperature deformation, filling the sealing gap, improving cold resistance, and improving practicality.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
