[0032] The present utility model will be described in detail below with reference to the drawings:

[0033] As Figure 1 and Figure 2As shown in the figure, a temperature reminder includes: a housing 101; a magnet member 201 fixed to the housing; and a temperature sensor 202 fixed inside the housing.

[0034] The housing can adopt various common shapes. As an implementation, the housing is selected as a cuboid, cube, elliptical three-dimensional structure, triangular three-dimensional structure, etc. On the one hand, the housing provides an installation space for the components therein, and at the same time, it can also protect the components inside, avoiding the adverse effects of the external environment on the components inside the housing. In this embodiment, the housing is of a cuboid structure.

[0035] See Figure 3 , the housing 101 includes a bottom case 301 and a top cover 302, and the two are hermetically butted through a connecting member. The connecting member is generally a bolt member, and the two are fixedly installed through the screw holes provided on the bottom case 301 and the top cover 302.

[0036] The housing 101 is provided with the magnet member 201, a temperature sensor 303, a control main board 304 (using a PCB board), a display screen 305, a backlight board 306, a button pressing plate 307, a function button 308, and a battery 313. During actual installation, the magnet member, temperature sensor, control main board, and display screen can be installed on any part of the bottom case and the top cover. In this embodiment, the magnet member and temperature sensor are fixed to the bottom case. The control main board and the display screen are fixed to the top cover.

[0037] The function button 308 includes a power on / off key, a setting key, a temperature increase setting key, a temperature decrease setting key, etc.

[0038] The top cover 302 is provided with a transparent display area 309 and a function button area 310; the display screen 305 is correspondingly installed in the display area. A display window is provided at the position of the top cover 302 corresponding to the transparent display area 309, and a crystal sticker is covered on the display window. The display window and the crystal sticker form the transparent display area. The function button area 310 is provided with the function button 308 for temperature setting, etc. The function button 308 is fixed to the housing 101 through the button pressing plate 307. The inner wall of the top cover 302 is provided with multiple groups of corresponding positioning posts and installation grooves, etc., for fixing the positions of the control main board 304 (using a PCB board), the display screen 305, the backlight board 306, the button pressing plate 307, etc. The display screen 305, the backlight board 306, and the control main board 304 are correspondingly installed inside the top cover. Among them, the display screen 305 is fixed in the corresponding installation groove provided on the top cover 302 and is signal-connected to the control main board 304 through signal lines, etc. The control main board 304 and the key pressing plate 307 are provided with positioning holes corresponding to the above-mentioned positioning posts.

[0039] An alarm unit that is signal - connected to the control main board is also provided inside the housing 101. The control main board and the display screen are installed inside the housing. The control main board can receive the temperature signal from the temperature sensor and transmit the received temperature signal to the display screen for display. At the same time, it is connected to the alarm circuit of the alarm unit. The alarm unit uses a buzzer 311. When the temperature meets the set requirements, the buzzer gives an alarm to remind the on - site personnel that the temperature is abnormal.

[0040] One side of the top cover 302 is provided with a charging port and a charging port plug 312. When charging the battery, the charging port plug 312 can be opened. Inside the bottom case 301, a battery installation area is provided at the same time. The battery 313 is fixed in the battery installation area of the bottom case 301 through a battery fixing member 314. In this embodiment, the battery can be selected from a conventional battery or a rechargeable battery, etc., to provide power for the temperature reminder.

[0041] At the same time, referring to Figure 4 , the magnet member and the detection end of the temperature sensor are arranged on the same side of the housing. At this time, a magnet mounting seat 315 and a temperature sensor mounting seat 316 are also provided inside the bottom case 301. The magnet mounting seat is provided with a threaded bolt member 317 and a nut member 318 in a threaded fit. At the position of the outer wall of the bottom case 301 corresponding to the mounting seat, a magnet mounting groove is provided. The magnet member is fixed in the magnet mounting groove. At this time, the bottom of the magnetic member is flush with the bottom end of the bottom case 301.

[0042] The temperature sensor 303 is fixed inside the temperature sensor mounting seat 316, and its detection end ( Figure 3 in this case, the bottom end) protrudes slightly from the bottom case 301, that is, the detection end of the temperature sensor 303 is slightly higher than the bottom end of the magnet member. During use, ensure that the sensor is closely attached to the object surface to check the temperature. Of course, the temperature detector can also be adsorbed on an iron object to detect the temperature of the normal room air, etc.

[0043] In addition to the installation method of this embodiment, the magnet member can be installed inside the housing or on the outer wall of the housing. It can be fixed to the housing by using other positioning members, or the magnet member can be integrally provided on the housing. For example, the sensor can also be fixed in the gap between the magnet member and the bottom case 301 and directly adsorbed on the object through the magnet to transmit the sensed temperature. The magnet member can also be placed inside the housing and fixed with glue, or fixed in a snap - fit form, or embedded in the plastic during production and formed by packaging.

[0044] Alternatively, a magnetic attraction property can be adopted. For example, at least a part of the housing is made of a material containing ferromagnetic substances, and at this time, the magnet component can be directly attracted and fixed at the corresponding position of the housing; or, a magnetic attraction component capable of attracting and fixing the magnet component is provided inside the housing, and the magnetic attraction component can be used to realize the attraction and fixation of the magnet component. The magnetic attraction component can be a magnet group paired with the magnet component. During installation, one magnet component is placed inside the housing, and after the installation is completed, the other magnet component is attracted to the position where the internal magnet component is located to realize the positioning and installation of the external magnet component.

[0045] When the present utility model is actually used, it is attracted and fixed on the surface of a magnetic object by using the magnet component thereon to realize the temperature detection of the object surface; or the temperature reminder of the present utility model can be directly fixed on a magnetic metal part to realize the detection of the air temperature, etc. When the temperature is abnormal, the buzzer gives an alarm.

[0046] Furthermore, the steps are as follows;

[0047] Press the power key and hold it for 3 seconds to turn on / off. When turning on, the current temperature is displayed; press the setting key and hold it for 3 seconds to enter the interface for selecting the high temperature HIGH or low temperature LOW setting, (factory setting: low temperature -20°C - high temperature 120°C or low temperature 0°C - high temperature 120°C), short press the setting key to select the high temperature HIGH - symbol, low temperature LOW - symbol; the digital display flashes; after confirming the high temperature or low temperature; press the + key (temperature increase setting key); enter the temperature setting, short press the + key, the number increases, long press the + key and the number will automatically increase; press the - key (temperature decrease setting key); enter the temperature setting, short press the - key, the number decreases, long press the - key and the number will automatically decrease; after selecting the set values of the high temperature and low temperature, long press the setting key for 3 seconds to exit, or automatically exit after more than 30 seconds, the number no longer flashes, and at this time, it enters the working state.

[0048] Taking the detection of the surface temperature of an object as an example, before use, first turn on the machine (long press the power on / off key for 3 seconds to turn on). After setting the temperature value, bring it close to the object surface and then magnetically attach it. If the preset temperature value is not reached after contact, there will be no alarm, indicating that the machine has entered the warning standby state. If the buzzer gives a dididi alarm reminder and the red light flashes, it means that the current temperature of the object to be detected is higher than the temperature value set by the machine. Press any key to pause the alarm. At this time, find the reason to solve the problem (check; whether the valve is open, or the waterway is blocked, or the object itself is in a high-temperature state, etc.). After dealing with the temperature of the object itself in time, then use this machine. For example, if the fault is not solved in time, the device will automatically give an alarm reminder again after 30 seconds. Note; if there is a certain distance between the object surface and the part to be detected, at this time, it depends on the detection device to judge the temperature difference between them. After the detection and comparison results, the set temperature value should be lower than the actual temperature value. For example, if the internal temperature of the object is 50° and the external surface is only 20°, this machine cannot set 50°, but should set 18° as the reminder standard, and set the temperature value according to the actual detection.

[0049] Set the required high and low temperature limit values. When this machine detects that the high temperature exceeds the set temperature value, the buzzer will give a dididi alarm and the red light will flash. Press any key to pause the alarm. Similarly, when the low temperature is lower than the set temperature value, the buzzer will give a dididi alarm and the red light will flash. Press any key to pause the alarm. If the fault cause is not solved in time, the device will alarm again until the fault is eliminated, unless it is shut down.

[0050] Set the temperature value. When the buzzer is giving a reminder, press any key to cancel it first, and then press the setting key to enter the next step.

[0051] Taking the processing technology of mold-produced parts as an example, high temperatures caused by various reasons have a certain impact on the quality of the produced parts (sudden failure of the water pump, blocked waterway, valve not opened or broken, wrong waterway connection, continuing production after high temperature, defective products, waste products, and deformed parts difficult to assemble produced by the mold due to a series of problems), directly causing economic losses. The temperature detector of the present utility model will give an alarm reminder in time to solve the problem in time, reducing the scrap rate; the advantages of using the temperature detector: constant temperature control (can effectively prevent: (1) the mold ejector pin being bitten and damaged after high temperature, affecting the mold accuracy and service life; (2) the burrs overflowing after high temperature; (3) the parts being deformed after high temperature; (4) the parts not being properly assembled after high temperature).
