[0033] Example
[0034] Please refer to Figure 1-Figure 6 The present embodiment provides a universal safety detection device for household appliances, comprising: a cabinet body, the cabinet body comprising a cabinet body 1 and a cabinet door 2, the cabinet body 1 is a trough structure, the cabinet door 2 is covered at the mouth of the trough structure, and the cabinet door 2 is hinged to the cabinet body 1; a temperature rise detection component, the temperature rise detection group comprises a plurality of temperature sensors 3 and a control panel 4, the temperature sensor 3 is arranged on the inner wall of the cabinet body 1, and the plurality of temperature sensors 3 are evenly spaced along the height direction of the cabinet body 1, the control panel 4 is arranged on the outer wall of the cabinet body 1, and the plurality of temperature sensors 3 are connected to the control panel 4; an adaptability detection component, the adaptability detection component comprises a heating mechanism, the heating mechanism comprises a heating element 5 and a guide fan 6, an air inlet 13 is provided at the top of the cabinet body 1, the heating element 5 is arranged on the cabinet body 1, and the heating element 5 is located at the mouth of the air inlet 13, the heating element 5 is electrically connected to the control panel 4, the guide fan 6 is arranged on the outer side of the cabinet body 1, and the output end of the guide fan 6 is aligned with the air inlet 13, and an air outlet 14 is provided at the middle and lower part of the cabinet body 1.
[0035] In this embodiment, the cabinet body is used to form a closed box structure through the cabinet body 1 and the cabinet door 2, which is convenient for monitoring the usage data of household appliances after they are running in the cabinet body, and can effectively obtain the temperature rise data and adaptability data of the household appliances.
[0036] Furthermore, the temperature rise component is used to obtain the temperature change of the whole environment caused by the use of household appliances in a fixed environment. Specifically, the temperature sensor 3 is used to obtain temperature data of different heights from low to high inside the cabinet body. The obtained temperature data is transmitted to the control panel 4 and then integrated and output for display, so that the monitor can read the temperature rise data of the household appliances in the cabinet body in real time.
[0037] In this embodiment, the adaptability detection component is used to pass high-temperature gas into the enclosed space formed by the cabinet body, so that the temperature inside the cabinet body continues to rise, thereby obtaining the adaptability data of the household appliance. Specifically, the heating element 5 is used to generate heat energy, and the guide fan 6 is used to pump the generated heat energy into the cabinet body, thereby raising the temperature inside the cabinet. In the continuously rising environment, the working status of the household appliances in the cabinet body can be monitored. The air outlet 14 is used for gas diversion. The heating element 5 and the heat-conducting fan are located at the top of the cabinet body. The generated hot air flow is continuously pushed down by the guide fan 6, thereby surrounding the hot air on the outside of the household appliance, so that it is at the temperature set by the control panel 4.
[0038] Please refer to Figure 1 and Figure 2 In some implementations of the present embodiment, an air inlet control mechanism is provided on the air inlet 13 located inside the cabinet body 1, and the air inlet control mechanism includes a slide rail 7, a baffle 8 and a driving member. There are two slide rails 7, and the two slide rails 7 are symmetrically arranged on the air inlet 13. The baffle 8 is slidably arranged in the slide rail 7. The driving member is arranged on the cabinet body 1, and the driving member is used to drive the baffle 8 to reciprocate on the slide rail 7.
[0039] In this embodiment, the above-mentioned air inlet control mechanism is used to control the opening and closing of the air inlet 13. When a temperature rise test is performed on household appliances placed inside the cabinet body, the baffle 8 is driven by the driving member to slide in the slide rail 7 to block the air inlet 13, thereby preventing a large amount of heat generated by the household appliances from being lost, thereby obtaining more accurate temperature rise data and improving the accuracy of the obtained data.
[0040] Specifically, the slide rail 7 is an L-shaped structure, which cooperates with the top of the cabinet body 1 to form a U-shaped structure. The baffle 8 is positioned in the gap formed by the two slide rails 7, so that the driving member can stably drive the baffle 8 to reciprocate on the air inlet 13.
[0041] Please refer to Figure 1 and Figure 2 In some implementations of the present embodiment, the driving component includes a driving motor 9 and a screw rod 10. The screw rod 10 is passed through the baffle plate 8, and the baffle plate 8 is threadedly connected to the screw rod 10. The driving motor 9 is arranged in the cabinet body 1, and the driving motor 9 is connected to the screw rod 10.
[0042] It should be noted that the screw 10 is a long cylinder with threads on the surface. The baffle 8 is provided with a plate body with internal threads. When the screw 10 rotates, the baffle 8 moves along the axis of the screw 10 due to the guiding effect of the slide rail 7. Specifically, when force or torque is applied to the screw 10, the screw 10 rotates by engaging the threads on its surface with the internal threads of the nut. Due to this spiral engagement, the rotational movement of the screw 10 causes the nut to move along the axial direction of the screw 10, thereby achieving linear motion.
[0043] In this embodiment, the above-mentioned drive motor 9 is used to provide a power source. The drive motor 9 starts to drive the screw rod 10 to rotate, and the screw rod 10 rotates to drive the baffle 8 to slide on the slide rail 7, thereby controlling the opening and closing of the air inlet 13, which is convenient for providing a relatively sealed environment for the temperature rise test and improving the accuracy of data acquisition.
[0044] Please refer to Figure 1 and Figure 2 In some implementations of this embodiment, the driving motor 9 is a servo motor, and the output end of the servo motor is connected to the screw rod 10.
[0045] In this embodiment, the drive motor 9 is a servo motor, which is an engine that controls the operation of mechanical components in a servo system and is an auxiliary motor indirect speed change device. The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and speed to drive the control object. The excellent control accuracy of the servo motor is an ideal material for the drive motor 9, but it is not limited to the servo motor material, and can also be other materials with similar accuracy.
[0046] Please refer to Figure 3 and Figure 4 In some implementations of the present embodiment, a blocking mechanism is provided on the air outlet 14, the blocking mechanism includes a guide plate 11 and a sealing plate 12, a slide groove (not shown in the figure) is provided on the air outlet 14, the guide plate 11 is provided at the mouth of the slide groove, a sliding gap is formed between the guide plate 11 and the slide groove, and the guide plate 11 is slidably provided in the sliding gap.
[0047] In this embodiment, the above-mentioned blocking mechanism is used to control the opening and closing of the air outlet 14, so as to adjust the sealing of the test space according to the temperature rise test or the adaptability test, so that the user can adjust the sealing of the space according to the test type and improve the accuracy of data acquisition.
[0048] Specifically, the guide plates 11 are vertically arranged on both sides of the outlet end of the air outlet 14. The guide plates 11 cooperate with the slide groove to form a sliding gap to prevent the sealing plate 12 from falling out of the slide groove when sliding. The sliding direction of the sealing plate 12 is the height direction, so that when the air outlet 14 is closed, the guide plates 11 are pushed down. The guide plates 11 are blocked at the output end of the air outlet 14 due to their own gravity.
[0049] Please refer to Figure 3 and Figure 4 In some implementations of the present embodiment, the guide plate 11 is made of a magnetic material, and a magnetic strip 15 is provided on the cabinet body 1 at the top of the slide groove, and the guide plate 11 can abut against the magnetic strip 15 .
[0050] In this embodiment, the magnetic strip 15 is used to fix the guide plate 11 on the top of the slide slot, and the guide plate 11 is adsorbed and fixed by the magnetic force between the guide plate 11 and the magnetic strip 15, thereby connecting the cabinet body with the external air.
[0051] Please refer to Figure 1 , Figure 3 , Figure 5 and Figure 6 In some implementations of the present embodiment, a door frame 16 is provided on the cabinet body 1 , a sealing strip 17 is provided on the door frame 16 , and the cabinet door 2 can abut against the sealing strip 17 .
[0052] In this embodiment, the cabinet door 2 abuts against the sealing strip 17 of the door frame 16 , which can further improve the heat dissipation in the cabinet body and improve the accuracy of the acquired data.
[0053] Please refer to Figure 1 In some implementations of this embodiment, the inner wall of the cabinet body is covered with an insulation layer (not shown in the figure).
[0054] In this embodiment, the inner wall of the cabinet body is covered with an insulation layer for slowing down heat loss, which can reduce heat exchange through the side wall of the cabinet body 1 and improve the accuracy of data acquisition.
[0055] Please refer to Figure 6 In some implementations of this embodiment, a socket 18 for plugging in household appliances is provided in the cabinet body 1 .
[0056] In this embodiment, the socket 18 is used for plugging in the household appliance to be tested, so as to avoid damage to the plug cable of the household appliance by external plugging in the cabinet door 2 .
[0057] When in use, during the temperature rise test, close the air outlet 14 and the air inlet 13, drive the motor 9 to rotate, and the screw 10 connected thereto rotates, and the screw 10 rotates to drive the baffle 8 to move to the air inlet 13, and the operator pushes the sealing plate 12 down along the direction of the slide slot so that the sealing plate 12 blocks the air outlet 14, opens the cabinet door 2 and puts in the household appliance to be tested, plugs the electrical appliance plug into the socket 18 accordingly, closes the cabinet door 2, and connects the control circuit of the control panel 4, and obtains the temperature data inside the cabinet through the temperature sensor 3;
[0058] During the adaptability test, the drive motor 9 is driven in reverse so that the screw rod 10 drives the baffle 8 to slide in the slide rail 7, connecting the air inlet 13 with the cabinet body, and the control panel 4 controls the heating element 5 and the guide fan 6 to start moving, continuously inputting high-temperature gas into the cabinet body, and the sealing plate 12 is controlled by hand to move upward along the slide groove so that the sealing plate 12 is fixed on the magnetic strip 15, and the data on whether the household appliances are running stably is continuously obtained. When the test is completed, the cabinet door 2 is opened to take out the tested household appliances.
