DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-6 The utility model provides a technical solution: a large air volume heater, comprising: a shell 1, the shell 1 is composed of a front cover 2 and a rear cover 17, the front cover 2 and the rear cover 17 are connected by bolts; a switching assembly is arranged inside the front cover 2, the switching assembly comprises a switching cylinder 7 which can rotate to switch positions, a filter cover 9 is detachably mounted on one side of the switching cylinder 7, a filter screen 10 is mounted inside the filter cover 9 for purifying filtered air, a purification air outlet 8 is arranged at the position of the filter screen 10 corresponding to the switching cylinder 7, a heating air outlet 11 is arranged at the position adjacent to the filter screen 10 on the outside of the switching cylinder 7, and the heating air outlet 11 is distributed between the purification air outlet 8 and the filter mounting groove 18; a high-pressure fan 13 is arranged in the switching cylinder 7, an air outlet of the high-pressure fan 13 is fixedly mounted with an air outlet channel 14, the high-pressure fan 13 and the air outlet channel 14 are combined together to form a plurality of groups for increasing the exhaust air volume, and an electric heating wire is arranged in the middle of the air outlet channel 14 for heating the blown air.

[0025] It should be noted that the utility model is provided with a tipping-over shutdown protection device, a control panel and buttons. The temperature, wind speed and working mode are set through the control panel and buttons. The tipping-over shutdown protection device includes a tilt sensor or switch, which can sense whether the heater is in a tipping state. When the heater tips over, the sensor will be triggered and send a signal to the system to immediately cut off the power supply. Once the tipping sensor detects that the heater has tipped over, the tipping-over shutdown protection device will quickly cut off the power supply to prevent further power supply. When in use, when heating is needed, the connecting plate 5 and the switching cylinder 7 are driven to rotate on the outside of the fixed partition 12 by the switching motor 6, so that the filter 10 and the purification air outlet 8 overlap with the fixed partition 12, and the heating air outlet 11 corresponds to the air inlet of the outer casing 1. The high-pressure fan 13 discharges the indoor air into the air outlet duct 14, and then the air is heated by the heating wire in the air outlet duct 14 and then discharged; when heating is needed When it is used as an air purifier, the switching motor 6 drives the switching cylinder 7 to rotate so that the purification outlet 8 is directly opposite to the outlet position of the air outlet channel 14, and the filter 10 is located at the air inlet position of the high-pressure fan 13. At this time, the heating outlet 11 is blocked by the fixed partition 12, and the front and rear ventilation structure is formed inside the switching cylinder 7. The high-pressure fan 13 draws the indoor air into the switching cylinder 7. During this process, the filter 10 filters the air, and then the filtered air is discharged through the air outlet channel 14 and the air outlet 4. The switching structure enables the heater to have both heating and air purification functions, providing more usage options. Users can switch working modes at any time as needed, so that they can enjoy warmth and improve indoor air quality. This versatility makes the heater more flexible in different seasons or usage scenarios. When the user wants to purify the air only without additional heating, he can choose to switch the heater to air purification mode. In this mode, stopping heating can reduce energy consumption and save electricity, thereby achieving energy-saving and environmental protection effects.

[0026] like Figure 3 , 4 As shown in FIG. 6 , the switching assembly also includes a switching motor 6 , which is fixedly connected in the front cover 2 , the output end of the front cover 2 is fixedly connected to a connecting disk 5 , and the switching cylinder 7 is fixedly connected to the bottom of the connecting disk 5 .

[0027] It should be noted that the utility model drives the switching cylinder 7 to rotate on the outside of the fixed partition 12 through the switching motor 6. When heating, the switching cylinder 7 is driven to rotate by the switching motor 6, so that the filter cover 9 and the purification air outlet 8 overlap with the fixed partition 12, to prevent the filter 10 from causing resistance to the wind and affecting the heating effect. When the air needs to be purified, the switching motor 6 drives the switching cylinder 7 so that the purification air outlet 8 is opposite to the air outlet position of the air outlet channel 14, and the filter 10 is located at the air inlet position of the high-pressure fan 13. The exhaust process increases filtration, thereby achieving air purification through the HEPA filter.

[0028] like Figure 4 , 6 As shown, a fixed plate 16 is fixedly connected to the interior of the front cover 2, and two arc-shaped fixed partitions 12 are fixedly connected to the top of the fixed plate 16. The air outlet channel 14 is fixedly connected to the fixed partition 12. The fixed partition 12 is installed inside the switching cylinder 7. The fixed partition 12 is concentric with the switching cylinder 7, and a sealing gasket is provided on the outside of the fixed partition 12. The fixed partition 12 is slidably connected to the switching cylinder 7.

[0029] It should be noted that the fixed plate 16 of the utility model is fixedly connected to the front cover 2, the fixed partition 12 is fixedly connected to the fixed plate 16, the bottom of the switching cylinder 7 is in contact with the fixed plate 16, and the purification air outlet 8 or the heating air outlet 11 is blocked and sealed by the fixed partition 12, so that the air can only flow in the middle of the air outlet channel 14.

[0030] like Figure 1 , 2 As shown in Figure 3, an air outlet 4 is provided on one side of the front cover 2, and an air inlet is provided on one side of the rear cover 17.

[0031] It should be noted that in the present invention, air enters through the air inlet and is discharged through the air outlet 4, thereby circulating to heat or purify the indoor air.

[0032] like Figure 1 , 2 As shown in 3 , the bottom of the housing 1 is rotatably connected to the base 3 , the interior of the front cover 2 is fixedly connected to a rotating motor, and the output end of the rotating motor is fixedly connected to the base 3 .

[0033] It should be noted that the front cover 2 of the utility model is fixedly connected to the rotating motor by bolts. When the rotating motor reciprocates, the housing 1 reciprocates on the top of the base 3 under the reaction of the force. The reciprocating heater can evenly distribute the hot air throughout the room. By swinging, the heater can cover a wider area, ensuring that the entire room can be evenly heated, rather than just concentrated in one direction, which can avoid the accumulation of hot air in one direction, thereby improving the heating effect. The air in the room will be heated more evenly, reducing the existence of hot and cold areas, and providing a more comfortable heating experience.

[0034] like Figure 4 As shown, a filter installation groove 18 that cooperates with the filter cover 9 is opened on one side of the switching cylinder 7.

[0035] It should be noted that the filter cover 9 and the filter mounting groove 18 of the utility model are both step-shaped structures, and the two sides fit together. The outer side of the switching cylinder 7 is arc-shaped. When the filter cover 9 and the switching cylinder 7 are assembled, the switching cylinder 7 is embedded and installed in the filter mounting groove 18, so that the switching cylinder 7 and the filter cover 9 form a complete circle without any protrusions, so that the switching cylinder 7 will not be hindered during the rotation process. Strong magnets are provided at the connection between the switching cylinder 7 and the filter cover 9, and the magnetic poles are opposite to each other. Under the action of suction, the filter cover 9 fits tightly in the filter mounting groove 18.
