Above the sliding track 31, the left-right moving component 5 includes a slide rail connecting rod 51, which is placed in the sliding track 31 to control the left-right movement of the PTC heating component 4 in the sliding track 31; when the slide rail connecting rod 51 is pushed to the left, the left-right moving component 5 slides to the left elastic limiter 8, and the slide rail connecting rod 51 contacts the left elastic limiter 8 and then abuts on the left elastic limiter 8; when the slide rail connecting rod 51 is pushed to the right, the left-right moving component 5 slides to the right elastic limiter 9, and the slide rail connecting rod 51 contacts the right elastic limiter 9 and then abuts on the right elastic limiter 9.

[0028] In this embodiment, if Figure 6As shown, a limiting groove 510 is provided on one side of the slide rail connecting rod 51 toward the left elastic limiting piece 8 and the right elastic limiting piece 9. When the slide rail connecting rod 51 is pushed to the left, the left-right moving component 5 slides to the left elastic limiting piece 8, and the left elastic limiting piece 8 contacts the slide rail connecting rod 51 and abuts against the limiting groove 510; when the slide rail connecting rod 51 is pushed to the right, the left-right moving component 5 slides to the right elastic limiting piece 9, and the right elastic limiting piece 9 contacts the slide rail connecting rod 51 and abuts against the limiting groove 510.

[0029] In this embodiment, if Figure 5 As shown, the left elastic limiter 8 and the right elastic limiter 9 include a fixing portion 81 and an elastic arm 82, wherein one end of the fixing portion 81 is fixed on the PTC bracket 3; the other end is bent to extend an elastic arm 82, and the elastic arm 82 is bent downward to form an abutment portion 83; when the slide rail connecting rod 51 is pushed to the left, the left-right moving component 5 slides to the left elastic limiter 8, and the abutment portion 83 contacts the slide rail connecting rod 51 and abuts in the limiting groove 510; when the slide rail connecting rod 51 is pushed to the right, the left-right moving component 5 slides to the right elastic limiter 9, and the abutment portion 83 contacts the slide rail connecting rod 51 and abuts in the limiting groove 510.

[0030] In this embodiment, the fixing portion 81 is provided with a fixing hole 810 , and the PTC bracket 3 is provided with a mounting hole 32 matched with the fixing hole 810 .

[0031] In this embodiment, the PTC bracket 3 is further provided with a limiting portion 33 for limiting the fixing portion 81, and the limiting portion 33 is L-shaped. The limiting portion 33 is designed to be L-shaped for limiting the left elastic limiting member and the right elastic limiting member to prevent the left elastic limiting member and the right elastic limiting member from moving and affecting the actual use effect.

[0032] In this embodiment, the left-right moving component 5 also includes a mounting seat 52 , a mounting groove 520 is provided on the top of the mounting seat 52 , the PTC heating component 4 is installed in the mounting groove 520 , and the slide rail connecting rod 51 is horizontally arranged in the middle of the mounting seat 52 .

[0033] In this embodiment, the PTC heating component 4 includes a PTC heating element 41 and a PTC fixing seat 42. The PTC heating element 41 is installed in the PTC fixing seat 42. The top of the PTC fixing seat 42 is provided with a mounting column 43 adapted to the mounting groove 520. The mounting column 43 is fixedly connected to the mounting groove 520.

[0034] In this embodiment, the micro switch assembly 6 includes a fixing seat 61 and a plurality of micro switches 62 . The fixing seat 61 is installed on the PTC bracket 3 . The left and right ends of the fixing seat 61 are respectively provided with placement portions 63 . The micro switches 62 are located in the placement portions 63 .

[0035] In this embodiment, a hand lever 10 is sleeved on one end of the slide rail connecting rod 51 away from the mounting seat 52 .

[0036] In this embodiment, a notch 84 is provided between the fixing portion 81 and the elastic arm 82, and the notch 84 is in an open shape. The purpose of designing the notch 84 in an open shape is to make the force arm of the elastic arm 82 longer, so that its elastic effect is better, so that the abutting portion 83 can slide more smoothly in the limiting groove 510.

[0037] Specifically, Figure 3 As shown, when the tower fan is used in actual cooling and heating, when it is switched to the cold air gear, the slide rail connecting rod 51 contacts the left elastic limiter 8 and then abuts against the left elastic limiter 8 to limit the position of the micro switch 62. When it is switched to the warm air gear, the slide rail connecting rod 51 contacts the right elastic limiter 9 and then abuts against the right elastic limiter 9 to limit the position of the micro switch 62, thereby ensuring that the tower fan can work normally.

[0038] like Figure 1 As shown, a decorative cover 11 is provided on the front shell 1, and an air outlet 12 is provided on the decorative cover 11, and an air outlet grille 13 is installed on the air outlet 12. When the heating component is slid to the position facing the air outlet grille 13, the micro switch 62 on the right side is pressed by the PTC fixing seat 42. After the micro switch 62 on the right side is pressed, the trigger program controls the PTC heating element 41 to start working. At this time, the wind drum 7 blows the hot air generated by the PTC heating element 41 out along the air outlet grille 13, so that the warm air gear works normally. A PCB control board 14 is also provided in the shell, and the PCB control board 14 is electrically connected to the wind drum 7 and the PTC heating element 41.

[0039] like Figure 4 As shown, the limiting structure formed by the slide rail connecting rod 51 and the right elastic limiting member 9 can effectively fix the heating component and prevent the micro switch 62 from sensing abnormalities.

[0040] When the slide rail connecting rod 51 is manually pushed to slide out of the limiting groove 510, the micro switch 62 is disconnected, and the PTC heating element 41 stops working, that is, the warm air gear stops working.

[0041] When the slide rail connecting rod 51 is manually pushed to the other side of the tower fan, that is, the PTC heating element 41 leaves the air outlet grille 13, the micro switch 62 on the left is pressed by the PTC fixing seat 42. After the micro switch 62 on the left is pressed, the wind blower 7 starts to work, realizing the normal operation of the cold air gear.

[0042] When the cold air gear is working normally, when the slide rail connecting rod 51 is pushed to the left, the left and right moving components 5 slide to the left elastic limiter 8, and the left elastic limiter 8 contacts the slide rail connecting rod 51 and abuts against the limiter groove 510. The limiter structure formed can effectively fix the PTC heating component 4 to prevent the micro switch 62 from sensing abnormalities.

[0043] The decorative cover 11 is provided with a PTC slide rail 15 , and micro switches 62 are respectively provided on the left and right sides of the PTC fixing seat 42 . When the hand lever is turned, the slide rail connecting rod 51 moves in the PTC slide rail and can move the PTC heating element 41 at the same time.

[0044] The slide rail connecting rod 51 is pushed to the right, driving the PTC fixing seat 42 and the PTC heating element 41 to move to the right at the same time. When the abutting portion 83 contacts the slide rail connecting rod 51 and slides into the limit groove 510 on the slide rail connecting rod 51, the micro switch 62 on the right side is pressed by the PTC fixing seat 42. After the micro switch 62 on the right side is pressed, the PCB control board 14 program is triggered to control the air blower 7 and the PTC heating element 41 to start working. The air blower 7 blows the hot air generated by the PTC heating element 41 out along the air outlet grille 13, realizing the normal operation of the warm air gear.

[0045] The slide rail connecting rod 51 is pushed to the left, and the slide rail connecting rod 51 leaves the abutting portion 83. At this time, the micro switch 62 on the right stops working, and the PCB control board 14 program controls the air blower 7 and the PTC heating element 41 to stop working.

[0046] Continue to move the slide rail connecting rod 51 to the left, when the abutting portion 83 of the left positioning spring slides partially into the limiting groove 510 of the slide rail connecting rod 51, the left micro switch 62 is pressed by the PTC fixing seat 42, and after the left micro switch 62 is pressed, the PCB control board 14 program is triggered to control the air blower 7 and the PTC heating element 41 to start working. The air blower 7 blows the hot air generated by the PTC heating element 41 out along the air outlet grille 13, so that the warm air gear works normally.

[0047] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
