Description

Technical Field

[0001] This invention belongs to the field of temperature controller technology, specifically relating to a temperature controller with automatic reset capability. Background Technology

[0002] A thermostat is a series of automatic control elements or electronic components that generate on or off actions based on the physical deformation inside the switch caused by temperature changes in the working environment. These elements produce certain special effects and provide temperature data to the circuit by adjusting the different operating states of the components at different temperatures.

[0003] Fluid medium temperature controllers utilize the principle of thermal expansion and contraction of temperature-sensitive fluids and the incompressibility of liquids to achieve automatic regulation. When the controlled temperature rises, the expansion of the temperature-sensitive fluid generates thrust that reduces the flow of the heating medium, thereby lowering the output temperature. When the controlled temperature decreases, the temperature-sensitive fluid contracts, and under the action of a reset device, the flow of the heating medium increases, thereby raising the output temperature, thus enabling the controlled temperature to reach and be maintained within the set temperature range. Color temperature type temperature controllers work on the principle that some coatings produce different colors at different temperatures. For example, liquid crystal displays can produce different colors at different temperatures, and color sensors such as cameras can provide different data to the circuit for control. Bimetallic strip temperature controllers work on the principle of thermal expansion and contraction. Thermal expansion and contraction is a common property of objects, but different objects expand and contract to different degrees. The two sides of the bimetallic strip are conductors of different materials. Due to the different degrees of expansion and contraction at changing temperatures, the bimetallic strip bends, touching a set contact or switch, thus activating the set circuit.

[0004] Bimetallic strips utilize the shape changes of conductors at different temperatures to protect or connect circuits. However, the set temperature is often a fixed value to conduct the circuit, and there are not many protective structures to protect the circuit from overvoltage, resulting in low safety performance. In addition, the design of the buffer components on electronic components is relatively simple, only able to provide corresponding buffer protection against vertical vibrations of electronic components, and cannot achieve comprehensive safety protection, which is not conducive to the use of the device and has poor applicability. Summary of the Invention

[0005] The purpose of this invention is to provide an automatically resettable temperature controller to solve the technical problems that the circuit can only be turned on when the set temperature is a fixed value, and there are not many protection structures to realize the overvoltage protection of the circuit, resulting in low safety performance and relatively simple design of the buffer components on the electronic components.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pest control trapping device, comprising:

[0008] The first biological trapping mechanism includes a first box fixed on a base plate. A conical funnel is detachably installed on the top of the first box via an annular baffle. A first motor is installed at the bottom of the first box. The output shaft of the first motor extends to a first bearing via a crossbeam. The top of the first bearing is connected to an insect-attracting lamp via a bent rod. The insect-attracting lamp is arranged in a ring shape and is connected to the conical funnel via a fixed rod.

[0009] The bottom opening of the conical funnel is provided with a movable cavity connected to the insect-attracting lamp. The extended ends on both sides of the top of the crossbeam are connected to a rotating plate placed between the side wall of the first box and the conical funnel. The rotating plate is provided with a through hole that matches it. Below the rotating plate are a first collection box and a second collection box placed on both sides of the bottom of the inner wall of the first box.

[0010] Furthermore, the first and second collection boxes have a rotating groove at their center that is connected to the output shaft of the first motor. The first collection box is filled with water, and the vertical extension ends of the bending rod are fixedly connected by a bracket.

[0011] Furthermore, the bottom of the rotating plate has a slot and is fixed to the extended end of the top of the crossbeam by plugging in, and the outer edge of the rotating plate has a rotating groove that connects to the conical funnel.

[0012] Furthermore, it also includes a second biological trapping mechanism, which includes a second motor fixed at both ends of the outer wall of the second box. One end of the output shaft of the second motor is connected to a movable shaft that rotates in the same direction. The movable shaft and the outer wall of the box are connected by a second bearing. The box is filled with sugar, and air holes penetrating the interior are opened around the box.

[0013] Furthermore, a bidirectional cam is fixedly installed on the outer wall of the movable shaft. Both the upper and lower ends of the bidirectional cam movably abut against the push rod. One end of the push rod is connected to the upper pressure plate and the lower pressure plate, respectively. The upper pressure plate and the lower pressure plate are connected to the inner wall of the second box through the first spring and the second spring, respectively.

[0014] Furthermore, the movable shaft and the first rotating shaft on the first bevel gear are connected by a first conveyor belt. The outer wall of the first bevel gear meshes with a second bevel gear fixed on the reciprocating screw. The bottom end of the reciprocating screw is movably connected to the support plate. A slider is screwed on the reciprocating screw. One end of the slider is connected to a limit groove along the height direction of the support plate, and the other end is connected to a baffle plate placed on the guide groove of the second housing.

[0015] Furthermore, one end of the guide channel is installed on the first housing through a conduit, the output shaft of the first motor and the second rotating shaft are connected by a second conveyor belt, one end of the second rotating shaft is fixed on the third bevel gear, the outer wall of the third bevel gear meshes with a fourth bevel gear, the central shaft on the fourth bevel gear and the central shaft of the first rotating tooth are connected by a third conveyor belt, and the outer wall of the first rotating tooth meshes with a second rotating tooth.

[0016] Furthermore, the central shaft of the second rotating tooth and the third rotating shaft are connected by a fourth conveyor belt. One end of the central shaft of the first rotating tooth and the third rotating shaft both pass through the guide tube and extend to the guide plate. The upper and lower ends of the inner wall of the guide tube are integrally formed with baffles. The inner wall of the baffles is provided with a stable part and a narrowing part connected to the first box body in the direction of airflow. A movement area for organisms to pass through is formed between the baffles, and the baffles are provided with guide holes connected to the movement area.

[0017] Furthermore, one end of the second rotating shaft is provided with a retaining ring connected to the second conveyor belt, and the third bevel gear, the fourth bevel gear and the second rotating gear are all placed in the housing, which is connected to the guide tube by locking and fixing with a positioning pin.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] (1) In this invention, during the heating process, the active layer of the bimetallic strip bends towards the passive layer and drives the moving contact to adhere to the fixed contact, thereby connecting the circuit. In addition, the reciprocating screw can be driven to rotate under the action of the handle. With the help of the screw drive, the fixed contact on the first terminal piece can be fixed at different heights. In this way, the bimetallic strip can be bent to different degrees and the circuit can be connected by different temperature values. In addition, the adjustment rod on the line is a telescopic structure design. With the help of the fuse, the first terminal piece can move up and down normally. The fuse can act as an automatic reset element. At normal temperature, the polymer structure binds the conductive particles to form a conductive path and exhibits low resistance characteristics. When the temperature or current exceeds the threshold, the polymer structure is destroyed, resulting in increased resistance and cutting off the current to achieve protection, thereby improving the safety and stability of the equipment operation.

[0020] (2) In this invention, during the up-and-down vibration of the support plate on the electronic component, the telescopic rod moves downward and is buffered and adjusted by the first spring. In addition, during the downward movement of the telescopic rod, the force can be transmitted to the one-way gear plate. Under the action of gear meshing transmission, the annular pad on the two-way gear plate can be driven to move upward and provide a force opposite to the downward movement of the support plate. In this way, the downward vibration of the support plate will be converted into the mechanical movement of the transmission component and the reverse force, thereby improving the buffering effect when the electronic component is vibrated. Moreover, the two-way gear plate, in conjunction with the rotating gear, can increase the use effect of the equipment. In this way, even if a single transmission component is damaged, it will not affect the normal movement of the annular pad driven by the two-way gear plate, greatly increasing the applicability of the device. The design is reasonable. During the rotation of the rotating gear, in conjunction with the transmission action of the conveyor belt, it is converted into the rotational motion of the turntable again. Since the turntable is provided with an arc-shaped hole, the rolling ball on the second spring, during the process of limiting and contacting it, not only reduces the impact force through the back-and-forth contact action, but also ensures the normal rotation of the turntable. The impact is reduced through the stable contact process until the impact force is eliminated, thereby effectively ensuring the safety of the equipment.

[0021] (3) In this invention, when the support plate moves downward, the first slider and the second slider can move in the horizontal and vertical directions by means of the rotational connection of the swing rod and the synchronous downward movement of the lifting rod, thereby pushing the gas into the elastic airbag. The elastic airbag is distributed around the support plate by the inflation action, which can achieve a full-range buffering and adjustment effect around the support plate. Moreover, the support plate is provided with a protective plate to increase the contact area with the elastic airbag. By increasing the contact area, the pressure is reduced and the buffering effect is further improved. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference manual attached Figure 1 - Appendix Figure 9As shown, an automatically resettable temperature controller includes: a housing 1; a reset adjustment mechanism 2, the reset adjustment mechanism 2 including a support plate 3 placed inside the housing 1, a positioning post 4 fixedly installed on the top of the support plate 3, a first wiring piece 5 and a second wiring piece 6 respectively installed at the upper and lower ends of the positioning post 4, a fixed contact 7 installed at the bottom of the first wiring piece 5, and a moving contact 9 corresponding to the fixed contact 7 installed on the second wiring piece 6 through a bimetallic strip 8;

[0035] A rotating handle is installed on the extended end of the positioning post 4. The bottom of the rotating handle is fixed on the reciprocating screw 10. The first connecting piece 5 is screw-driven on the reciprocating screw 10. The positioning post 4 is provided with a guide groove connected to the first connecting piece 5. The top side of the first connecting piece 5 is connected to the panel 12 through the adjusting rod on the fuse 11.

[0036] During heating, the active layer 14 of the bimetallic strip 8 bends towards the passive layer 15, causing the moving contact 9 to adhere to the fixed contact 7, thereby connecting the circuit. In addition, the rotating handle can drive the reciprocating screw 10 to rotate, and with the help of screw transmission, the fixed contact 7 on the first terminal piece 5 can be fixed at different heights. This allows the bimetallic strip 8 to bend to different degrees and connect the circuit through different temperature values. Furthermore, the adjusting rod on the circuit has a telescopic structure design, which, together with the fuse 11, allows the first terminal piece 5 to move up and down normally. The fuse 11 can act as an automatic reset element. At normal temperature, the polymer structure binds the conductive particles to form a conductive path, exhibiting low resistance characteristics. When the temperature or current exceeds the threshold, the polymer structure is destroyed, causing the resistance to increase, cutting off the current to achieve protection, thereby improving the safety and stability of the equipment operation.

[0037] Specifically, rotating the handle can drive the reciprocating screw 10 to rotate. In order to increase the automation effect of the equipment, the handle can also be set as a micro motor. The motor can also drive the reciprocating screw 10 to rotate by starting the motor. The above-mentioned motor setting is a conventional technical means that is obvious to those skilled in the art, and will not be described in detail here. The first connecting piece 5 is screwed on the reciprocating screw 10 and connected to the positioning post 4. The positioning post 4 not only provides the first connecting piece 5 with corresponding support force, but also allows the first connecting piece 5 to move freely up and down, providing corresponding guiding function for the screw drive.

[0038] The second connecting piece 6 and one side of the panel 12 are both equipped with a terminal 13. One end of the panel 12 is fixed to the positioning post 4 by a detachable installation method, and the panel 12 is provided with a movable hole for connecting to the reciprocating screw 10.

[0039] The positioning column 4 is fixed by a positioning pin and is connected to the bottom of the reciprocating screw 10. The outer edge of the reciprocating screw 10 is provided with a rolling groove connected to the cover plate. The bimetallic strip 8 is provided with an active layer 14 and a passive layer 15, and one side of the passive layer 15 is attached to the moving contact 9.

[0040] Connecting structural components by using locating pins for locking facilitates the installation and disassembly of these components, improves operator efficiency, and enhances the stability and robustness of the connections.

[0041] An automatically resettable temperature controller further includes a buffer adjustment mechanism 16. The buffer adjustment mechanism 16 includes telescopic rods 17 placed on both sides of the bottom end of the support plate 3. The fixed end of the telescopic rod 17 is connected to the bottom of the inner wall of the housing 1, and the movable part of the telescopic rod 17 is connected to the bottom of the inner wall of the fixed end through a first spring 18. The movable part of the telescopic rod 17 is connected to a one-way gear plate 20 extending into the inside of the first cover 19 through a bending rod.

[0042] The outer wall of the one-way gear plate 20 is engaged with a rotating gear 21 symmetrical about the center of the first cover 19. The outer wall of the rotating gear 21 is engaged with a two-way gear plate 22 that moves in the opposite direction to the one-way gear plate 20. A bracket that penetrates the interior of the first cover 19 is installed on the top of the two-way gear plate 22. An annular pad 23 that moves against the support plate 3 is installed on the top of the bracket. The annular pad 23 is made of resin or rubber.

[0043] Specifically, a limit plate 24 is connected to the one-way gear plate 20 along the height direction of the side wall of the first cover 19. The first rotating shaft 25 on the rotating gear 21 and the second rotating shaft 27 inside the second cover 26 are connected by a conveyor belt 28. One end of the conveyor belt 28 passes through the first cover 19 and extends into the second cover 26. One end of the second rotating shaft 27 is connected to the inner wall of the second cover 26 by a bearing, and the other end is mounted on the turntable 29.

[0044] The limiting plate 24 on the side wall height direction of the first cover 19 has the function of limiting and adjusting the movement of the one-way gear plate 20, preventing the one-way gear plate 20 from deviating in position during movement, thereby ensuring the stability of the transmission component during movement. The one-way gear plate 20 and the two-way gear plate 22 both have movable cavities inside the first cover 19, which facilitates the free up and down movement of the one-way gear plate 20 and the two-way gear plate 22.

[0045] During the vertical vibration of the support plate 3 on the electronic component, the telescopic rod 17 moves downward and is buffered by the first spring 18. Furthermore, the downward movement of the telescopic rod 17 transmits force to the one-way gear plate 20. Under the meshing transmission of the gears, it drives the annular pad 23 on the two-way gear plate 22 to move upward and provides a force opposite to the downward movement of the support plate 3. Thus, the downward vibration of the support plate 3 is converted into mechanical motion and a reverse force in the transmission components, thereby improving the buffering effect when the electronic component is subjected to vibration. Moreover, the two-way gear plate 22, in conjunction with the rotating gear 21, enhances the usability of the equipment. Even if a single transmission component is damaged, it will not affect the normal movement of the bidirectional gear plate 22 driving the annular pad 23, greatly increasing the applicability of the device. The design is reasonable. During the rotation of the rotating gear 21, in conjunction with the transmission action of the conveyor belt 28, it is converted into the rotational motion of the turntable 29. Since the turntable 29 is provided with an arc-shaped hole 30, the rolling ball 31 on the second spring 33, during the process of limiting and resisting it, not only reduces the impact force through the back-and-forth movement of the resisting action, but also ensures the normal rotation of the turntable 29. The impact force is reduced through a stable resisting process until the impact force is eliminated, thereby effectively ensuring the safety of the equipment.

[0046] The outer wall of the turntable 29 has annularly arranged arc-shaped holes 30. The outer wall of the arc-shaped holes 30 movably abuts against the rolling ball 31. The rolling ball 31 movably fits into the arc-shaped groove of the contact plate 32. The size of the rolling ball 31 corresponds to that of the annularly distributed arc-shaped holes 30. The contact plate 32 and the inner wall of the second cover 26 are connected by a second spring 33.

[0047] Lifting rods 34 are fixedly installed on both sides of the bottom end of the support plate 3. The lifting rods 34 and the first slider 35 are connected by a swing rod 36. One end of the first slider 35 is connected to a first piston 38 placed inside the guide tube 37 through a push rod, and the vertical end of the lifting rod 34 is connected to a second piston 39 placed inside the guide tube 37 through a second slider 41.

[0048] In addition, the swing rod 36 is mounted on the first slider 35 and the lifting rod 34 by means of rotational connection on both sides. The first piston 38 and the second piston 39 are vertically arranged. The guide tube 37 has a communication port connected to the first piston 38 and the second piston 39. The air port at one end of the guide tube 37 is connected to the elastic airbag 40. The elastic airbag 40 is distributed around the support plate 3. The outer edge of the support plate 3 is detachably equipped with a protective plate connected to the elastic airbag 40.

[0049] As the support plate 3 moves downward, the rotational connection of the swing rod 36 and the synchronous downward movement of the lifting rod 34 allow the first slider 35 and the second slider 41 to move simultaneously in the horizontal and vertical directions within the conduit 37 using the first piston 38 and the second piston 39. This pushes gas into the elastic airbag 40, and the inflation action causes the elastic airbag 40 to be distributed around the support plate 3. This provides a comprehensive buffering and adjustment effect around the support plate 3. Furthermore, the support plate 3 is equipped with a protective plate that expands the contact area with the elastic airbag 40. By increasing the contact surface, the pressure is reduced, further improving the buffering effect.

[0050] The protective plate on the elastic airbag 40 is not shown in the accompanying drawings. The protective plate is essentially a side plate on the outer wall of the support plate 3, used to increase the contact area with the elastic airbag 40. This is a conventional technical means for those skilled in the art, and therefore does not affect the effective implementation of the technical solution of the present invention.

[0051] The first piston 38 and the second piston 39 are each provided with a sealing ring on one side that connects to the side wall of the conduit 37. The outer wall of the conduit 37 is threaded and installed on the elastic airbag 40 by means of threaded connection. The first piston 38 and the second piston 39 move horizontally and vertically at the same time, which can quickly compress the gas into the elastic airbag 40, thereby increasing the buffer protection effect of the outer wall of the support plate 3.

[0052] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification.
