Description

Technical Field

[0001] This utility model relates to the field of sensor technology, specifically to an intelligent temperature and humidity transmitter. Background Technology

[0002] A temperature and humidity transmitter is a device equipped with temperature-sensitive and heat-sensitive elements to measure temperature and humidity. It is suitable for temperature and humidity measurement in environments such as communication equipment rooms, offices, workshops, warehouses, hospitals, HVAC systems, and building automation systems. It is mainly used in intelligent constant temperature and humidity control or energy-saving scenarios in these locations. However, existing temperature and humidity transmitters still have some shortcomings.

[0003] For example, the existing patent document CN201510973132.7 discloses a temperature and humidity transmitter housing, which includes a U-shaped insulating shell and a cover plate; the outer periphery of the opening of the U-shaped insulating shell is provided with a flange, and threaded holes are provided on the edge of the cover plate and the flange, which are fixedly connected by bolts; a hollow waterproof joint is provided on one side of the U-shaped insulating shell; a control board is built into the U-shaped insulating shell, and a central processing unit, a communication chip and a temperature and humidity control element are provided on the control board. The temperature and humidity detection probe connected to the temperature and humidity control element extends out from the hollow cavity of the hollow waterproof joint; a groove is provided at the top of the opening of the U-shaped insulating shell, and a sealing ring is placed in the groove.

[0004] However, the aforementioned housing can only be fixed with screws. In environments with high requirements for air temperature, humidity, and energy efficiency, such as communication equipment rooms or data centers, a large number of temperature and humidity transmitters are deployed to obtain temperature and humidity data from various parts of the environment, forming a comprehensive environmental dataset. The control system then analyzes and interprets this data before sending commands to devices such as air conditioners, humidifiers, and fresh air systems to adjust the ambient temperature and humidity. Because of the large number of temperature and humidity transmitters required and their varying installation locations, traditional screw-drilling installation is not only inefficient but also requires drilling into the mounting surface, which can easily cause resentment from the client. Especially when installed inside critical equipment, it can easily damage the equipment. If adhesive methods are used, problems such as detachment or inability to adjust the position can easily occur.

[0005] Therefore, it is necessary to design an intelligent temperature and humidity transmitter that can be installed in multiple ways and is securely fixed. Utility Model Content

[0011] As one embodiment of this utility model, the outer contour of the aforementioned limiting block is circular, and a pair of elastic limiting rods are also provided on the buckle bracket, with the lower end of each elastic limiting rod abutting against the limiting block.

[0012] In one embodiment of this utility model, the two aforementioned elastic limiting rods are arranged symmetrically, and each elastic limiting rod is inclinedly set on the buckle bracket, so that the lateral projection length of each elastic limiting rod is greater than the vertical distance from the limiting block to the buckle bracket.

[0013] As one embodiment of this utility model, a guide rail locking groove is provided on the back of the mounting housing, a locking strip is provided at the bottom of the guide rail locking groove, an upper locking block that cooperates with the locking strip is provided at the lower end of the buckle bracket, a strong magnetic block is provided in the guide rail locking groove, and the width of the guide rail locking groove is 35mm.

[0031] Example 1

[0032] This utility model is mainly used in communication equipment rooms or data centers, where there are high requirements for air temperature and humidity and energy conservation. Moreover, in order to achieve the required accuracy, this utility model will be deployed extensively in the scene to obtain temperature and humidity data of various parts of the scene, forming a comprehensive environmental dataset. After comprehensive analysis and judgment by the control system, instructions will be sent to the execution equipment such as air conditioners, humidifiers, and fresh air systems to adjust the environmental temperature and humidity.

[0033] This utility model relates to an intelligent temperature and humidity transmitter, which is particularly suitable for computer rooms, databases, and other occasions where a large number of temperature and humidity monitoring devices need to be installed. The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0034] like Figures 1-6 As shown, the intelligent temperature and humidity transmitter of this utility model mainly includes a mounting housing 1 and a heat dissipation housing 2. The mounting housing 1 and the heat dissipation housing 2 are interlocked to form a mounting cavity 100. A magnetic metal block 3 and a sensor circuit board 4 are disposed in the mounting cavity 100.

[0035] like Figure 1-2 As shown, the intelligent temperature and humidity transmitter of this utility model mainly includes a mounting housing 1 and a heat dissipation housing 2, which are fastened together by snaps or screws to form a sealed mounting cavity 100. The dimensions of the mounting housing 1 and the heat dissipation housing 2 are 65mm × 45mm. The entire housing is made of plastic material, and the overall size is small and compact, making it easy to carry and fix.

[0036] The magnetic metal block 3 is made of square or round iron blocks, which are used to cooperate with external strong magnetic adsorption, making it easy to install the entire temperature and humidity transmitter.

[0037] Sensor circuit board 4 integrates a temperature and humidity sensor, a signal processing circuit, and a communication module, which is used to collect environmental data and output signals through a cable.

[0038] like Figures 2-4 As shown, a strong magnetic block 7 is also provided below the threaded mounting hole 6. Ventilation grilles 21 are evenly arranged around the circumference of the heat dissipation housing 2. The ventilation grilles 21 on the heat dissipation housing 2 promote air circulation. The sensor circuit board 4 can accurately measure and monitor real-time temperature changes and send them to the control system for comprehensive analysis to promptly detect abnormal points.

[0039] The bottom of the heat dissipation housing 2 is equipped with a cable connector 8, which has a power interface 81 and an RS485 interface 82. The power interface 81 supports DC 12V / 24V power supply. The RS485 interface 82 is used for data communication, connecting to the data center of the control system. The cable connector 8 connects the power and communication cables. After the device is powered on, it automatically collects ambient temperature and humidity data.

[0040] The back of the mounting housing 1 has threaded mounting holes 6, which can be used to fix the entire device by passing bolts through the threaded mounting holes 6 in sequence and then fixing it into the threaded holes on the wall or equipment.

[0041] The mounting housing 1 has a guide rail slot 13 on the back for placing a strong magnetic block 7, which can be directly attached to a metal surface and is suitable for temporary or mobile monitoring needs.

[0042] like Figure 2-5 As shown, the back of the mounting housing 1 is provided with an elastic mounting buckle 5 and a threaded mounting hole 6. The elastic mounting buckle 5 on the back of the mounting housing 1 can be fixed in the buckle groove 11 by the buckle bracket 51, and the entire temperature and humidity transmitter can be suspended on a nail at the measurement location by the hanging hole 52 on the buckle bracket 51.

[0043] A snap-fit ​​groove 11 is provided on the back of the mounting housing 1, and the elastic mounting buckle 5 is snapped into the snap-fit ​​groove 11.

[0044] like Figures 5-6 As shown, the elastic mounting buckle 5 includes a buckle bracket 51, on which a mounting hole 52 and a pair of mounting buckles 53 are provided, and each mounting buckle 53 abuts against the inner side wall of the buckle groove 11.

[0045] The clip bracket 51 has a mounting hole 52 and a pair of mounting buckles 53. During installation, the mounting buckles 53 abut against the inner wall of the clip groove 11. To ensure stability, a limiting block 12 with a circular outer contour and a limiting groove 120 is provided inside the clip groove 11. The clip bracket 51 has a limiting post 54 that is inserted below the limiting groove 120 to prevent the clip from coming out.

[0046] like Figure 4 and Figure 6 As shown, a guide rail slot 13 is provided on the back of the mounting housing 1. A locking strip 131 is provided at the bottom of the guide rail slot 13. An upper locking block 56 that cooperates with the locking strip 131 is provided at the lower end of the buckle bracket 51. The strong magnetic block 7 is provided in the guide rail slot 13. The guide rail slot is 35mm in size. Through the cooperation of the locking strip 131 and the upper locking block 56, the mounting housing 1 can be directly snapped onto the circuit breaker rail of the distribution box or the power module rail of the integrated rack.

[0047] like Figure 6 As shown, a limiting block 12 is provided in the buckle groove 11, a limiting groove 120 is provided on the limiting block 12, and a limiting post 54 is provided on the buckle bracket 51, with the limiting post 54 located below the limiting groove 120.

[0048] With the cooperation of the limiting post 54 and the limiting groove 120, when the buckle bracket 51 and the mounting housing 1 are displaced under the action of external force, the limiting groove 120 can lock the limiting post 54 to prevent the buckle bracket 51 from falling off.

[0049] The outer contour of the limiting block 12 is circular, and a pair of elastic limiting rods 55 are also provided on the buckle bracket 51, with the lower end of each elastic limiting rod 55 abutting against the limiting block 12.

[0050] Two elastic limiting rods 55 are arranged symmetrically, and each elastic limiting rod 55 is inclinedly mounted on the buckle bracket 51.

[0051] The tilt angle is 60 degrees, so that the lateral projection length of each elastic limiting rod 55 is greater than the vertical distance from the limiting block 12 to the buckle bracket 51. A pair of elastic limiting rods 55 are symmetrically tilted, and their lateral projection length is greater than the distance from the limiting block 12 to the buckle bracket 51, providing elastic support and preventing the buckle bracket 51 from falling off.

[0052] The flexible mounting buckle 5, through the cooperation of the buckle bracket 51, the limiting post 54 and the limiting block 12, combined with the symmetrically arranged flexible limiting rods 55, effectively prevents loosening caused by vibration or external impact, and ensures long-term stable fixation.

[0053] The magnetic metal block 3 is a square or round iron block. In this embodiment, a square iron block is used. The design of the strong magnetic block 7 and the magnetic metal block 3 can be directly adsorbed onto the metal surface, or the strong magnetic block 7 can be placed on the back of the location to be measured by clamping. It is generally a thin non-metallic material, and then the entire temperature and humidity transmitter is attached to it, so that the magnetic metal block 3 and the strong magnetic block 7 inside the temperature and humidity transmitter are magnetically attracted.

[0054] The back of the mounting housing 1 is provided with a guide rail slot 13, and the strong magnet 7 is placed in the guide rail slot 13. The guide rail slot 13 is 35mm wide. The guide rail slot 13 can not only be used as a space to store the strong magnet 7, but also, because the guide rail slot 13 is 35mm wide, it can be directly snapped onto the circuit breaker rail of the distribution box or the power module rail of the integrated rack.

[0055] With a dual fixing method of flexible mounting clip 5 and threaded mounting hole 6, it supports both quick snap-on installation and secure connection with bolts, making it suitable for different installation scenarios and further expanding the installation methods to meet temporary or mobile monitoring needs.

[0056] This utility model has four quick installation methods to meet the needs of quick fixing in any installation position in places such as computer rooms and databases. By setting magnetic metal blocks and strong magnetic blocks, it can be directly magnetically attracted. The strong magnetic blocks can be attracted into the guide rail slot, and then directly attracted to the surface of ferromagnetic materials such as the inside or outside of communication equipment, cable trays, and the inner wall of electrostatic floor.

[0057] It can perform a clamping operation. After separating the two strong magnetic blocks from the mounting housing, place them on the opposite side of the mounting surface and clamp the mounting surface with the strong magnetic blocks on the product. It is suitable for non-ferromagnetic thin sheet materials such as ceiling panels, PVC cable trays, and aluminum equipment frames.

[0058] This invention improves the external structure of the temperature and humidity transmitter and adds multiple fixing connection methods, enabling the temperature and humidity transmitter to be installed quickly and in large quantities at various detection points.

[0059] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0060] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
