Description

Technical Field

[0001] This utility model relates to the field of electronic product technology, and in particular to a magnetically detachable temperature recorder. Background Technology

[0002] Temperature data loggers, as electronic measuring devices used to continuously collect and store ambient temperature or object surface temperature, are widely used in cold chain logistics, equipment operation monitoring, industrial manufacturing process control, and experimental data acquisition. Existing temperature data loggers are typically installed at the measurement location using screws, adhesives, or binding methods. The installation and disassembly process is cumbersome, especially in applications requiring frequent deployment or replacement of measurement points. This results in low operational efficiency and can easily damage the surface of the measured equipment.

[0003] On the other hand, many existing temperature recorders place the temperature sensing element directly inside the housing and sense the measured temperature through heat transfer from the housing. Since the housing material is mostly plastic, its thermal conductivity is limited, resulting in slow measurement response speed and large measurement error, making it difficult to meet the need for rapid and accurate acquisition of the surface temperature of an object.

[0004] Therefore, we propose a magnetically attached detachable temperature recorder to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a magnetically detachable temperature recorder.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a magnetically detachable temperature recorder, comprising a front shell and a bottom shell, wherein the front shell and the bottom shell are interlocked to form an instrument housing;

[0007] The bottom of the base shell is symmetrically provided with magnet mounting slots, and each magnet mounting slot is press-fitted with a magnet block by an interference fit.

[0008] The bottom shell has a PCB board inside, and an electronic button is provided on the PCB board. The front shell has a button hole corresponding to the position of the electronic button, and a plastic button that can trigger the electronic button is installed in the button hole.

[0009] The PCB board is provided with a temperature sensing element, and a metal heat-conducting component is fixedly installed on the bottom shell. One end of the metal heat-conducting component is thermally connected to the temperature sensing element, and the other end is exposed outside the bottom shell to contact the object to be measured.

[0010] The bottom shell is provided with a battery compartment, and the battery compartment contains a battery body for powering the PCB board.

[0011] Preferably, the battery compartment is closed by an openable battery door, and a door sealing ring is provided between the battery door and the bottom shell. The battery body is electrically connected to the PCB board through a battery positive electrode and a battery negative electrode disposed in the battery compartment.

[0012] Preferably, the bottom shell is fitted with an outer silicone ring, and the top corner of the outer silicone ring is provided with a lifting hole.

[0013] Preferably, the front shell, the bottom shell, and the PCB board are fastened together by screws.

[0014] Preferably, a thermally conductive medium is filled between the metal thermally conductive element and the temperature sensing element.

[0015] Preferably, a nameplate is affixed to the outer surface of the face shell, and a protective sticker is affixed to the bottom of the bottom shell, the protective sticker covering the outer end face of the metal heat-conducting component and the bottom surface of the magnet block.

[0016] Preferably, a reset button is provided on the battery door, and a reset switch corresponding to the reset button is provided on the PCB board. Pressing the reset button can trigger the reset switch to control the PCB board to reset.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model allows the temperature recorder to be directly adsorbed onto an iron or magnetic mounting surface by symmetrically setting magnet mounting slots at the bottom of the base shell and pressing and fixing the magnet block with an interference fit. This enables a quick and easy installation method that can be used immediately without the need for tools. It is also easy to disassemble without damaging the surface of the object being measured, making it particularly suitable for multi-point, temporary, or inspection-type temperature monitoring scenarios.

[0019] By setting a metal heat-conducting component on the bottom shell, with one end thermally connected to the temperature sensing element and the other end directly exposed to the outside of the shell and in contact with the object being measured, the heat conduction path is significantly shortened. Combined with the filling of the heat-conducting medium, the contact thermal resistance is effectively reduced, thereby improving the response speed and measurement accuracy of temperature acquisition and avoiding the measurement lag problem caused by insufficient thermal conductivity of the shell material.

[0020] The electronic buttons are located on the PCB board and are triggered by the button holes on the front cover and the plastic buttons, so that daily operations are concentrated on the front of the front cover. The reset button is independently located at the battery door and is arranged in correspondence with the reset switch on the PCB board to avoid accidental activation. Attached Figure Description

[0027] 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.

[0028] Example 1

[0029] like Figures 1-4 As shown, the present invention proposes a magnetically detachable temperature recorder, which includes a front shell 3 and a bottom shell 8. The front shell 3 and the bottom shell 8 are interlocked to form a sealed instrument housing. To enhance the overall structural strength and connection stability of the housing, the front shell 3, the bottom shell 8 and the PCB board 13 built into the housing are fastened together by multiple screws 2.

[0030] To enable the instrument to be easily and firmly attached to the ferromagnetic metal surface, two magnet mounting slots are symmetrically machined on the bottom of the base shell 8. Each magnet mounting slot contains a magnet block 15 press-fitted in an interference fit, thereby providing a reliable magnetic attraction force for the recorder.

[0031] To prevent the magnet blocks 15 from attracting foreign objects or being scratched during transportation or when not in use, and to protect the heat-conducting interface, a protective sticker 16 is attached to the bottom of the bottom shell 8. The protective sticker 16 completely covers the bottom surface of the two magnet blocks 15 and the exposed end face of the metal heat-conducting component 14.

[0032] The PCB board 13 serves as the control and recording center, on which temperature sensing elements are soldered. To achieve accurate and rapid temperature measurement, a metal heat-conducting component 14 is mechanically fixed to the bottom shell 8. One end of the metal heat-conducting component 14 extends into the shell and forms a tight thermal connection with the temperature sensing element on the PCB board 13. Typically, this connection is filled with a high-performance thermal grease or other thermally conductive medium to ensure heat transfer efficiency. The other end of the metal heat-conducting component 14 passes through and is exposed at the bottom of the bottom shell 8, for direct contact with the surface of the object to be measured, thereby efficiently transferring external temperature to the internal temperature sensing element.

[0033] The instrument is powered by the battery body 9. The bottom shell 8 has a battery compartment specifically for accommodating the battery body 9. The battery compartment contains a flexible positive electrode 4 and a negative electrode 5. When the battery body 9 is inserted, the positive and negative electrodes of the battery establish a stable electrical connection with the PCB board 13 through these two electrodes. The opening of the battery compartment is closed by an openable battery door 11. A door sealing ring 10 is installed at the joint surface between the battery door 11 and the bottom shell 8 to ensure the airtightness of the battery compartment and prevent moisture from entering.

[0034] An electronic button 12 is provided on the PCB board 13. Correspondingly, a button hole is opened on the front cover 3. A plastic button is installed in the button hole. When the user presses this plastic button, the internal electronic button 12 can be triggered to realize functions such as power on / off and mode switching.

[0035] To facilitate device reset after the battery door 11 is closed, a reset button 6 is located on the inside of the battery door 11. A reset switch is provided at a corresponding position on the PCB board 13. Specifically, a small hole is provided on the battery door 11 corresponding to the position of the reset button 6. When a reset is required, the user can use a long, thin tool such as a probe to insert through this hole and press the reset button 6 directly, thereby triggering the reset switch on the PCB board 13 to reset the device.

[0036] To improve the overall protection level and portability of the instrument, an outer silicone ring 7 is fitted on the outside of the bottom shell 8. This silicone ring enhances the buffer performance of the device. At the same time, a lifting hole is designed at its top corner, which makes it easy for the user to apply force to remove the recorder in the adsorbed state from the metal surface. Finally, a nameplate 1 is affixed to the outer surface of the front shell 3 to mark the product model, parameters and other information.

[0037] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
