[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1-8 The wireless transmission IoT intelligent temperature and pressure sensor device includes: a temperature and pressure sensor 1, a front cover body 2 and a transparent plate 3 mounted on the temperature and pressure sensor 1. The temperature and pressure sensor 1 is the temperature and pressure sensor device described in patent document CN221006412U. The front cover body 2 and transparent plate 3 are components of it, and also include components such as an antenna and a signal acquisition generator, thus achieving the effect of wireless transmission IoT intelligence. Therefore, further details are omitted here. A transparent protective cover 4 is provided on one side of the temperature and pressure sensor 1, and the transparent plate 3 on the temperature and pressure sensor 1 is located inside the transparent protective cover 4 to form protection. A rubber seal is fixedly installed on the side of the transparent protective cover 4 near the front cover body 2. A sealing ring 5 is provided, which is in contact with one side of the front cover body 2 to ensure a sealing effect. Two hollow sleeves 6 are fixedly installed on the front cover body 2, and the side of the hollow sleeves 6 near the transparent protective cover 4 is open. Two positioning arms 7 are fixedly installed on the outer wall of the transparent protective cover 4. One side of the two positioning arms 7 is inserted into the two hollow sleeves 6 respectively, and the positioning arms 7 are in contact with the inner wall of the hollow sleeves 6. The two positioning arms 7 are provided with a countersunk hole 8 on the side away from each other. The two hollow sleeves 6 are slidably installed with a transverse insert 13 on the side away from each other. The two transverse inserts 13 are inserted into the two countersunk holes 8 respectively at the ends that are close to each other. In this way, the transparent protective cover 4 can be fixed on the temperature and pressure sensor 1.

[0027] In the above method, to facilitate subsequent replacement of the damaged transparent protective cover 4, a spring sheet 9 is provided in each of the two hollow sleeves 6. The two spring sheets 9 are in contact with the two positioning arms 7 respectively. Guide posts 10 are slidably installed on the two hollow sleeves 6 away from the transparent protective cover 4. The ends of the two guide posts 10 near the transparent protective cover 4 are fixedly connected to the two spring sheets 9 respectively. Spring covers 11 are fixedly installed on the ends of the two guide posts 10 away from the transparent protective cover 4. A return spring 12 is fitted on each of the two guide posts 10, with one end fixedly connected to the hollow sleeve 6 and the other end fixedly connected to the spring cover 11. Furthermore, sliding pieces 14 are fixedly installed on the ends of the two transverse inserts 13 that are far apart from each other. A return spring 2 15 is fitted on each of the two transverse inserts 13. The ends of the two return springs 2 15 that are far apart from each other are fixedly connected to the two sliding pieces 14 respectively, and the ends that are close to each other are fixed to the two hollow sleeves 6 respectively. The transverse insert 13 is connected, and one end of the transverse insert 13 located in the countersunk hole 8 is set as a hemispherical surface. The positioning insert 7 is provided with a contacting bevel 3 on one side of the hollow sleeve 6. The contacting bevel 3 is adapted to the hemispherical surface of the transverse insert 13. In addition, an adapter block 16 is fixedly installed on one side of each of the two sliding plates 14. Two connecting posts 17 are fixedly installed on the side of the temperature and pressure sensor 1 away from the transparent protective cover 4. The same bracket strip 18 is slidably installed on the two connecting posts 17. Two connecting cranks 19 are fixedly installed on the side of the bracket strip 18 near the temperature and pressure sensor 1. A push head 20 is fixedly installed on the side of each of the two connecting cranks 19 away from the bracket strip 18. The two push heads 20 are respectively in contact with and adapted to the two adapter blocks 16. By pushing the bracket strip 18, the transverse insert 13 can be automatically brought out of the countersunk hole 8 by the cooperation between the push head 20 and the adapter block 16, so that the transparent protective cover 4 can be removed for replacement.

[0028] In the above method, in order to provide stable linear motion for the sliding piece 14, limit slide rods are fixedly installed on the outer walls of the two hollow sleeves 6 on opposite sides. The two limit slide rods pass through the two sliding pieces 14 respectively and are slidably connected to the corresponding sliding pieces 14.

[0029] In this method, in order to enable the pressed frame strip 18 to automatically return to its original position, baffles are fixedly installed at the ends of the two connecting posts 17, and reset springs 21 are sleeved on the two connecting posts 17. The two ends of each reset spring 21 are fixedly connected to the temperature and pressure sensor 1 and the frame strip 18, respectively. When the frame strip 18 is pressed, the reset spring 21 is in a compressed state. When the frame strip 18 is released, the compressed reset spring 21 rebounds, thereby enabling the frame strip 18 to return to its original position.

[0030] In this method, in order to create a sliding contact effect between the push head 20 and the adapter block 16, a first contacting edge is provided on the side of each adapter block 16 near the push head 20, and a second contacting edge is provided on the side of each push head 20 near the adapter block 16. The first contacting edge is adapted to the second contacting edge respectively.

[0031] The working principle of the wireless transmission IoT intelligent temperature and pressure sensor device provided by this utility model is as follows:

[0032] In daily use of temperature and pressure sensor 1, reset spring 12 is in a stretched state, and under the protection of transparent protective cover 4, transparent plate 3 is not directly hit or struck by external objects, thus providing good protection.

[0033] In subsequent use, when the transparent protective cover 4 needs to be replaced due to damage to the transparent plate 3 caused by external impact or severe damage, simply push the connecting strip 18 towards the temperature and pressure sensor 1. The connecting strip 18 will move along with the two connecting cranks 19, and the return spring 21 will gradually be compressed. When the second abutting edge on the push head 20 contacts the first abutting edge on the adapter block 16, the two abut against each other, causing the two adapter blocks 16 to move away from each other. At this time, the two return springs 15... As the force gradually stretches, the two transverse inserts 13 move horizontally along with the adapter block 16. When the transverse inserts 13 move out of the locking hole 8, the stretched return spring 12 rebounds instantly, pushing the two positioning arms 7 out of the hollow sleeve 6, so that the damaged transparent protective cover 4 can be removed. At this time, the bracket strip 18 is released, and the return spring 2 15 and the return spring 3 21 rebound, bringing the bracket strip 18 back to its original position. At the same time, the transverse inserts 13 are reinserted into the hollow sleeve 6.

[0034] Then, take out the new transparent protective cover 4 and insert the two positioning arms 7 into the corresponding hollow sleeve 6. During the insertion process, when the three-sided abutting edge of the positioning arm 7 contacts the hemispherical surface of the transverse insert 13, it will squeeze the transverse insert 13, causing the two transverse inserts 13 to move away from each other, so that the positioning arm 7 can smoothly penetrate into the hollow sleeve 6. At this time, the second return spring 15 is in a stretched state. When the transverse insert 13 is horizontally aligned with the countersunk hole 8, the stretched return spring 15 rebounds, thereby automatically locking the transverse insert 13 into the countersunk hole 8, thus completing the replacement of the transparent protective cover 4.

[0035] Compared with related technologies, the wireless transmission IoT intelligent temperature and pressure sensor device provided by this utility model has the following advantages:

[0036] This utility model provides a wireless transmission IoT intelligent temperature and pressure sensor device. The transparent protective cover 4 can form a protective layer around the transparent plate 3 on the front cover body 2, which can prevent the transparent plate 3 from being directly hit or struck by external objects. This improves the service life of the temperature and pressure sensor 1 to a certain extent. Furthermore, the damaged transparent protective cover 4 can be removed and replaced later by pressing the bracket strip 18. The operation is simple and quick, making it convenient for people to use.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
