Description

Technical Field

[0001] This utility model relates to the field of electrical accessories, and in particular to a smart sensor junction box. Background Technology

[0002] In home renovation, junction boxes are one of the electrical accessories. Because the wires used in renovation run through conduits, junction boxes are used as transition points at the wire joints. The conduits connect to the junction boxes, and the wires inside the conduits are connected in the junction boxes, which serves to protect and connect the wires. Junction boxes are generally designed to be openable and closable. With the advancement of technology, junction boxes with built-in smart sensors are gradually becoming popular. The smart sensors inside these junction boxes can help electricians find circuit faults based on parameters such as current and air humidity inside the junction box.

[0003] However, existing smart sensor junction boxes still have some shortcomings. Because they are buried in walls or electrical cabinets for a long time, they are rarely opened to avoid loose wires. During the rainy season, the humidity inside the junction box increases, and the moisture cannot be removed in time. As a result, even with the assistance of sensor detection, the internal circuit of the junction box may be damaged by the time people discover the fault, causing inconvenience to people's production and daily life. Therefore, a smart sensor junction box is needed to solve the above-mentioned shortcomings. Utility Model Content

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. In this utility model, by setting up a drying mechanism, a first drive motor is used as a power source. The operation of the first drive motor drives the heating roller on the right side to rotate. Under the drive of the transmission gear, the two heating rollers rotate simultaneously, so that the spiral stirring blades continuously stir the granular desiccant, drive the air flow in the wire box body, increase the contact area between the desiccant and the air, prevent the desiccant from clumping, improve the water absorption efficiency and utilization rate of the desiccant, ensure that the wire box body is always dry, and ensure the normal operation of the circuit.

[0014] 2. In this utility model, an insect-repelling mechanism is set up, using a second drive motor as a power source. The operation of the second drive motor drives the lead screw to rotate. When the second drive motor periodically reverses, it drives the slider to reciprocate in the forward and backward directions. The syringe assembly, which is composed of a sealing sleeve, piston, connecting rod, and connecting plate, is based on the same principle as a medical syringe. Due to the limitations of the one-way valve for inhalation and one-way valve for exhaust, when the slider drives the connecting plate to move backward, the piston moves backward, and the insect-killing gas compressed in the ointment box is drawn into the sealing sleeve. When the piston moves forward, the insect-killing gas in the sealing sleeve is sprayed out through the exhaust pipe and nozzle. Under the action of the fan blades, it is densely distributed throughout the wire box body to perform insect-repelling work, preventing insects from frequently crawling in the wire box body, which could cause the wire ends to fall off or the insects' limbs to touch the circuit and cause a short circuit, thus ensuring the normal operation of the circuit.

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0027] Example: Reference Figures 1-9 The smart sensor junction box shown includes a junction box body 1, a cover 2 rotatably connected to the rear side of the junction box body 1, a plastic latch 3 that cooperates with the cover 2 fixedly connected to the front side of the junction box body 1, a connecting piece 4 fixedly connected to the lower side of the junction box body 1, a fixing plate 5 fixedly connected to the inner wall of the junction box body 1, a wiring terminal 6 fixedly connected to the upper side of the fixing plate 5, a drying mechanism fixedly connected to the inner bottom wall of the junction box body 1, and an insect repellent mechanism fixedly connected to the inner bottom wall of the junction box body 1.

[0028] The drying mechanism includes a first mounting box 7 fixedly connected to the inner bottom wall of the wire box body 1. A first mounting plate 8 is fixedly connected to the inner bottom wall of the first mounting box 7. A second mounting plate 9 is fixedly connected to the inner bottom wall of the first mounting box 7. A heating roller 10 is rotatably connected to the front inner wall of the first mounting box 7. The rear end of the heating roller 10 passes through the front side of the first mounting plate 8 and is rotatably connected to the front side of the second mounting plate 9. A spiral stirring blade 12 is fixedly connected to the surface of the heating roller 10.

[0029] Using the above structure, a commonly used junction box model is formed by setting the junction box body 1, the box cover 2, the plastic buckle 3, the connecting piece 4, and the terminal block 6. The connecting piece 4 has a reserved mounting hole, which can be fixed to the wall using tools such as expansion bolts. The junction box with the box cover 2 can prevent the wire ends inside from falling off due to external objects. The fixing plate 5 has a large number of small ventilation holes. The fixing plate 5 isolates the terminal block 6 from the drying mechanism and the drive mechanism. The heating roller 10 is connected to the power supply and can generate a slight heat when powered on, heating the surrounding objects.

[0030] Preferably, there are two heating rollers 10. The two heating rollers 10 are symmetrically arranged on the front inner wall of the first mounting box 7 with the vertical center line of the front inner wall as the axis of symmetry. The surfaces of the two heating rollers 10 are fixedly connected with transmission gears 11. The two transmission gears 11 mesh with each other, and the rear side of the transmission gears 11 is rotatably connected to the front side of the first mounting plate 8.

[0031] By setting two transmission gears 11, the two heating rollers 10 can rotate in opposite directions. The first mounting plate 8 provides stable support for the installation of the heating rollers 10 and the transmission gears 11. In the first mounting box 7, some granular desiccant is placed in the gap between the first mounting plate 8 and the second mounting plate 9 to absorb moisture in the wire box body 1. The diameter of these desiccants is large and cannot pass through the vent holes of the fixing plate 5.

[0032] Preferably, a first drive motor 13 is fixedly connected to the rear side of the second mounting plate 9, the output end of the first drive motor 13 passes through the front side of the second mounting plate 9 and is fixedly connected to the rear end of the right heating roller 10, and a motion sensor is fixedly connected to the rear side of the second mounting plate 9.

[0033] By setting the first drive motor 13 as the power source, the first drive motor 13 drives the heating roller 10 on the right to rotate. Under the drive of the transmission gear 11, the two heating rollers 10 rotate simultaneously, so that the spiral stirring blades 12 continuously stir the granular desiccant, drive the air flow in the wire box body 1, increase the contact area between the desiccant and the air, avoid the desiccant from clumping, and improve the water absorption efficiency and utilization rate of the desiccant.

[0034] Preferably, the insect repellent mechanism includes a second mounting box 15 fixedly connected to the inner bottom wall of the wire box body 1. A limiting slide 17 is fixedly connected to the inner bottom wall of the second mounting box 15. The same lead screw 18 is rotatably connected to the inner walls of the front and rear sides of the limiting slide 17. A slider is threadedly connected to the surface of the lead screw 18. The surface of the slider is slidably connected to the inner wall of the limiting slide 17. A second drive motor 19 is fixedly connected to the front side of the limiting slide 17. The output end of the second drive motor 19 passes through the inner wall of the front side of the limiting slide 17 and is fixedly connected to the front end of the lead screw 18.

[0035] By setting a second drive motor 19 as a power source, the operation of the second drive motor 19 drives the lead screw 18 to rotate, thereby driving the slider to move.

[0036] Preferably, the insect repellent mechanism further includes a sealing sleeve 21 fixedly connected to the inner bottom wall of the second mounting box 15. A piston 22 is slidably connected to the inner wall of the sealing sleeve 21. A connection hole is provided on the rear side of the sealing sleeve 21. A connecting rod 23 is slidably connected to the inner wall of the connection hole. The front end of the connecting rod 23 is fixedly connected to the rear side of the piston 22. A connecting plate 20 is fixedly connected to the upper side of the slider. The front side of the connecting plate 20 is fixedly connected to the rear end of the connecting rod 23.

[0037] By setting up a syringe assembly with sealing sleeve 21, piston 22, connecting rod 23 and connecting plate 20, which is based on the same principle as a medical syringe, when the slider drives the connecting plate 20 to move backward, the piston 22 moves backward, and the external object is drawn into the sealing sleeve 21. When the slider drives the connecting plate 20 to move forward, the piston 22 moves forward, and the object in the sealing sleeve 21 is pushed outward.

[0038] Preferably, the insect repellent mechanism further includes a medicated plaster box 29 fixedly connected to the inner wall of the second mounting box 15, an air intake hole is provided on the front side of the sealing sleeve 21, an air intake pipe 24 is fixedly connected to the inner wall of the air intake hole, the end of the air intake pipe 24 away from the sealing sleeve 21 passes through the left inner wall of the medicated plaster box 29, an air intake one-way valve 25 is fixedly connected to the surface of the air intake pipe 24, an air outlet hole is provided on the front side of the sealing sleeve 21, an air outlet pipe 26 is fixedly connected to the inner wall of the air outlet hole, a nozzle 28 is fixedly connected to the end of the air outlet pipe 26 away from the sealing sleeve 21, an air outlet one-way valve 27 is fixedly connected to the surface of the air outlet pipe 26, and a fan blade 16 is fixedly connected to the inner wall of the second mounting box 15.

[0039] By setting an intake one-way valve 25 and an exhaust one-way valve 27 to restrict the direction of airflow, the airflow can only flow in one direction from the ointment box 29 into the sealing sleeve 21, and then flow in one direction from the sealing sleeve 21 to the outside. The ointment box 29 contains compressed insecticidal gas, which can kill insects that have entered the wire box body 1.

[0040] The working principle of this utility model is as follows: A smart sensor junction box is installed in a wall or tool cabinet using screws, expansion bolts, and other tools. After the wires are installed, the box cover 2 is closed and locked with a plastic lock 3. When the humidity sensor 14 detects a high moisture content in the junction box body 1, the fan blade 16, heating roller 10, first drive motor 13, and second drive motor 19 are connected to the circuit. The two heating rollers 10 heat up slightly, expelling moisture from the junction box body 1. The first drive motor 13 drives the right heating roller 10 to rotate. Under the action of the two transmission gears 11, the two heating rollers 10 begin to rotate in opposite directions, which in turn drives the two spiral stirring blades 12 to rotate. The movement of the two spiral stirring blades 12 agitates the desiccant, causing airflow in the junction box body 1, increasing the contact area between the desiccant and the air, preventing the desiccant from clumping, improving the water absorption efficiency and utilization rate of the desiccant, ensuring that the junction box body remains dry, and ensuring the circuit... In normal operation, the second drive motor 19 will periodically reverse direction after being connected to the circuit. The operation of the second drive motor 19 drives the lead screw 18 to rotate, which in turn drives the slider to reciprocate in the forward and backward directions. The movement of the slider drives the connecting plate 20 to move, which in turn drives the connecting rod 23 to move, which in turn drives the piston 22 to move. When the piston 22 moves backward, due to the restriction of the suction one-way valve 25 and the exhaust one-way valve 27, the insecticidal gas compressed in the ointment box 29 is drawn into the sealing sleeve 21. When the piston 22 moves forward, due to the restriction of the suction one-way valve 25 and the exhaust one-way valve 27, the insecticidal gas in the sealing sleeve 21 is sprayed out through the exhaust pipe 26 and the nozzle 28. Under the action of the fan blade 16, it is densely distributed in the entire wire box body 1 to repel insects. Since the wire box body 1 is generally not opened, the insecticidal gas in the wire box body 1 with good sealing conditions can maintain an effective concentration that can harm insects for a period of time.

[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
