Specific embodiments

[0026] The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Embodiment

[0028] As Figure 1-2 shown, a desktop heater proposed by the present utility model includes a base 1 and also includes a housing 2. The housing 2 is rotatably installed on the base 1. An installation rod 8 is fixedly installed in the base 1. One end of the installation rod 8 is rotatably installed with a fan 9. A heating plate 12 is fixedly installed in the base 1 for heating the air entering the interior of the housing 2. An auxiliary mechanism for preventing accidental contact with the air outlet and scalding is provided on one side of the base 1;

[0029] Among them, a sealing mechanism is arranged in the base 1 for sealing the interior of the base 1;

[0030] In addition, a protection mechanism is arranged on the base 1 for power-off when the base 1 is tilted.

[0031] As Figure 2-3 shown, this embodiment also includes an auxiliary mechanism. The auxiliary mechanism includes an air outlet plate 7 slidably installed on one side of the base 1. A plurality of connecting holes 19 arranged in an equidistant circular arrangement are formed on one side of the base 1. A plurality of connecting columns 11 arranged in an equidistant circular arrangement are fixedly installed on one side of the air outlet plate 7. The connecting columns 11 are slidably connected to the connecting holes 19. A track plate 20 is fixedly installed in the base 1. Guide plates 13 are fixedly installed on both sides of the air outlet plate 7. The guide plates 13 are slidably connected to the track plate 20. An inserting block 6 is slidably installed on the base 1. Jacks 14 are formed on the guide plates 13. The inserting block 6 is slidably connected to the jacks 14. Pull the inserting block 6 to remove the inserting block 6 from the jack 14 to cancel the fixation of the air outlet plate 7. Pull the air outlet plate 7 outwards to increase the distance between the air outlet plate 7 and the heating plate 12, so that the hot air blown out from the heating plate 12 can be cooled when it reaches the air outlet plate 7, avoiding scalding when a person accidentally touches due to the too high temperature of the air outlet plate 7. After use, reset the air outlet plate 7 and insert the inserting block 6 into the jack 14 to fix the air outlet plate 7 and reduce the occupied space.

[0032] As shown Figure 2-3 in the figure, the sealing mechanism is further included in this embodiment. The sealing mechanism includes a first connecting plate 18 fixedly installed on one side of the base 1. A second connecting plate 15 is rotatably installed on one side of the first connecting plate 18. A plurality of air inlet holes 16 arranged at equal distances are formed on both the second connecting plate 15 and the first connecting plate 18. When the device needs to be used, rotate the second connecting plate 15 to align the air inlet holes 16 on the first connecting plate 18 with the air inlet holes 16 on the second connecting plate 15, so that air can reach the inside of the housing 2 through the air inlet holes 16 and heat it. After use, rotate the housing 2 to keep one side of the air outlet plate 7 parallel to the bottom surface, and rotate the second connecting plate 15 to stagger the air inlet holes 16 on the first connecting plate 18 from the air inlet holes 16 on the second connecting plate 15 to seal the first connecting plate 18 and prevent dust from entering the device.

[0033] As shown Figure 2-3 in the figure, the power-off mechanism is further included in this example. The power-off mechanism includes a gravitational acceleration sensor 10 fixedly installed on one side of the mounting rod 8. The gravitational acceleration sensor 10 is perpendicular to the ground at this time. Set the trigger threshold of the gravitational acceleration sensor 10 to 30 - 40°. A power cord 3 is fixedly connected to the bottom of the base 1. A power controller 21 is fixedly installed on the power cord 3. The output end of the gravitational acceleration sensor 10 is connected to the input end of the power controller 21. When the housing 2 is tilted with respect to the bottom surface by more than 30°, the gravitational acceleration sensor 10 is triggered and transmits a signal to the power controller 21, and the power controller 21 cuts off the power to prevent the device from accidentally touching an object and causing a fire.

[0034] As shown Figure 2-3 in the figure, a pull plate 5 is fixedly installed on one side of the plug block 6. Anti-slip patterns are provided on the pull plate 5. A rotating block 17 is fixedly installed on one side of the second connecting plate 15. A plurality of convex blocks 22 arranged in a circular pattern at equal distances are fixedly installed on the rotating block 17. A connecting rod 4 is rotatably installed on the base 1. One end of the connecting rod 4 is fixedly connected to the housing 2.

[0035] The working principle of this embodiment is as follows: When the device needs to be used, rotate the second connecting plate 15 to align the air inlet hole 16 on the first connecting plate 18 with the air inlet hole 16 on the second connecting plate 15, so that air can reach the inside of the housing 2 through the air inlet hole 16 and heat it. After use, rotate the housing 2 to keep one side of the air outlet plate 7 parallel to the bottom surface, rotate the second connecting plate 15 to stagger the air inlet hole 16 on the second connecting plate 15 from the air inlet hole 16 on the second connecting plate 15, seal the first connecting plate 18 to prevent dust from entering the device. Pull the insertion block 6 to remove the insertion block 6 from the insertion hole 14, cancel the fixation of the air outlet plate 7, pull the air outlet plate 7 outwards to increase the distance between the air outlet plate 7 and the heating plate 12, so that the hot air blown out from the heating plate 12 can be cooled when it reaches the air outlet plate 7, avoiding scalding when people accidentally touch the air outlet plate 7 due to its too high temperature. After use, reset the air outlet plate 7, insert the insertion block 6 into the insertion hole 14 to fix the air outlet plate 7 and reduce the occupied space. When the housing 2 is tilted more than 30° from the bottom surface, the acceleration sensor 10 is triggered, and the signal is transmitted to the power controller 21. The power controller 21 cuts off the power supply to prevent the device from accidentally touching an object and causing a fire. It realizes avoiding scalding of personnel caused by accidental touch of the device, effectively preventing dust from entering the device, improving the service life of the device, and having a high installation coefficient for device use.
