DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] A desktop blowing machine, such as Figure 1 and Figure 2 As shown, it includes a placing table 1 and a bag blowing box 2, the packaging bag 17 is placed on the placing table 1, and a positioning piece for fixing the packaging bag 17 is provided on the placing table 1. A notch 6 is opened on the side of the bag blowing box 2 facing the placing table 1, and a hair dryer 4 is provided in the blowing box 2. An air duct 5 is provided at the air outlet of the hair dryer 4, and the air duct 5 passes through the notch 6, and the bottom of the air duct 5 is in contact with the connecting portion 18 of the uppermost packaging bag 17.

[0027] A gap 21 is provided at one end of the placement table 1 close to the blowing box 2. The gap 21 is provided along the width direction of the placement table 1 and penetrates the placement table 1. When placing the packaging bag 17, the through hole 19 on the packaging bag 17 is aligned with the gap 21. The positioning member is specifically a "U"-shaped plug block 3. Both ends of the plug block 3 respectively pass through the two through holes 19 on the connecting portion 18 of the packaging bag 17 and then penetrate into the gap 21, thereby fixing the packaging bag 17. The top of the plug block 3 fits with the topmost packaging bag 17.

[0028] The connecting portion 18 on the packaging bag 17 is connected to the side below the opening. After the air guide 5 extends to the connecting portion 18, the hair dryer 4 can blow open the opening of the packaging bag 17. After the user puts fruits and vegetables into the packaging bag 17, the packaging bag 17 is torn off along the tear line 20 on the connecting portion 18, and the hair dryer 4 continues to blow open the opening of the next packaging bag 17.

[0029] The upper cover 7 of the bag blowing box 2 is rotatably connected, and the rotation axis of the upper cover 7 is located at an end away from the placing table 1. The upper cover 7 is tilted downward toward one end of the placing table 1 to form a guide plate 701. The guide plate 701 extends onto the placing table 1, and the placing table 1 is tilted downward in a direction away from the bag blowing box 2. The inclination angle of the guide plate 701 is greater than that of the placing table 1. By setting the inclined guide plate 701, the user can slide fruits and vegetables into the packaging bag 17, and packaging is more convenient.

[0030] A pressing block 14 is provided at one end of the guide plate 701 facing the placement table 1. The pressing block 14 fits against the connecting portion 18 of the top packaging bag 17 and presses the connecting portion 18 downward by gravity, making the packaging bag 17 more stable and facilitating the hair dryer 4 to blow open the packaging bags 17 one by one.

[0031] like Figure 1 and Figure 3 As shown, the hair dryer 4 and the air duct 5 are fixed on the upper cover 7, the side wall of the hair dryer 4 is provided with an air inlet 9, an adjusting bracket 10 is fixed on the side wall of the hair dryer 4, the adjusting bracket 10 is threadedly connected with a screw 11, a wind shield 12 is fixed on the end of the screw 11 facing the air inlet 9, the shape and size of the wind shield 12 are the same as those of the air inlet 9, and the distance between the wind shield 12 and the air inlet 9 can be adjusted by rotating the screw 11, so that the size of the gap 21 between the wind shield 12 and the air inlet 9 changes, thereby adjusting the air intake of the hair dryer 4.

[0032] Flip the upper cover 7 upwards to start adjusting the hair dryer 4. A knob 13 is provided at the end of the screw 11 away from the air inlet 9, which is convenient for the user to rotate the screw 11. The knob 13 has anti-slip grooves to increase the friction with the fingers to prevent slipping.

[0033] Limit blocks 8 are arranged on both sides of the placement table 1 to prevent the packaging bag 17 from shifting. The limit blocks 8 are in contact with the side walls of the packaging bag 17 to fix the packaging bag 17 between the two limit blocks 8; the limit blocks 8 include a vertical plate 801 arranged vertically and a horizontal plate 802 arranged horizontally. The vertical plate 801 is in contact with the side walls of the packaging bag 17, and a slide groove 15 is opened on the horizontal plate 802 along the width direction of the placement table 1. A bolt 16 is arranged in the slide groove 15. The bolt 16 passes through the slide groove 15 and is threadedly connected to the placement table 1. The head of the bolt 16 is tightly pressed against the top of the horizontal plate 802, thereby fixing the limit blocks 8. The limit blocks 8 can be moved along the slide groove 15 by screwing the bolt 16 upwards, so that the limit blocks 8 can be suitable for packaging bags 17 of different widths.

[0034] The top of the vertical board 801 is tilted outward, and the spacing between the tops of the vertical boards 801 is greater than the width of the packaging bags 17 of corresponding sizes. The packaging bags 17 can be directly placed along the vertical boards 801, making it convenient for users to refill the packaging bags 17.

[0035] The working process of the utility model is as follows:

[0036] The whole stack of packaging bags 17 is placed on the placing table 1, the insert block 3 is inserted into the through hole 19 and inserted into the gap 21 to fix the packaging bag 17, the upper cover 7 is turned down to make the air duct 5 fit on the packaging bag 17, the hair dryer 4 blows air from the air duct 5 to blow open the opening of the packaging bag 17, and after the fruits and vegetables are put into the packaging bag 17, the packaging bag 17 is torn off, and the hair dryer 4 blows open the opening of the next packaging bag 17 in turn.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
