Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of 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.

[0030] Example 1: Please refer to Figures 1 to 6 :

[0031] The utility model proposes an automatic door opening mechanism of a dispenser, comprising: a main box body 1, a propulsion ear plate 2 and a driving motor 3, a box door 101 is hinged at the front of the main box body 1, a gas spring telescopic cylinder 102 is rotatably arranged on the side of the main box body 1, an outer protective cover body 104 is fixed on the outer side of the telescopic rod head end of the gas spring telescopic cylinder 102, a door opening ear plate 103 is fixed on the upper part of the box door 101, the outer protective cover body 104 surrounds the outer side of the telescopic rod of the gas spring telescopic cylinder 102, the outer protective cover body 104 slides on the outer side of the gas spring telescopic cylinder 102, the outer protective cover body 104 reduces the situation that the telescopic rod of the gas spring telescopic cylinder 102 is attached by dust, the telescopic rod head end of the gas spring telescopic cylinder 102 is rotatably connected with the side of the box door 101, and when the gas spring telescopic cylinder 102 is contracted, the box door 101 and the main box body 1 are in a closed state;

[0032] The upper part of the main box body 1 is provided with a push ear plate 2, the tail end of the push ear plate 2 is fixed with a tail nut 201, the center of the tail nut 201 is threaded with a screw rod 202, the head end of the screw rod 202 is fixed with a limit plate 203, the tail end of the screw rod 202 is fixedly connected to the light rod 204, the limit plate 203 is fixedly connected to the head end of the outer corrugated protective sleeve 205, the tail end of the outer corrugated protective sleeve 205 is fixed to the tail nut 201, and the outer corrugated protective sleeve 205 covers the outside of the screw rod 202 The outer corrugated protective sleeve 205 stretches and compresses as the distance between the tail nut 201 and the limit plate 203 expands or contracts. The outer corrugated protective sleeve 205 protects the screw 202 from dust and water. A driving motor 3 is arranged on the upper part of the main box body 1. An electromagnet 301 is fixed on the top of the driving motor 3. The electromagnet 301 can also be an electromagnetic spring structure. The electromagnet 301 is powered on and pushed to move. A tail push ring 302 is fixed to the tail end of the push rod of the electromagnet 301.

[0033] In the disclosed embodiment, the front end of the pushing ear plate 2 is rotatably connected to the door opening ear plate 103 by a pin, and the light rod 204 and the tail nut 201 slide through them. After the tail nut 201 disengages from the screw rod 202 and moves to the light rod 204, the thrust of the gas spring telescopic cylinder 102 finally pushes the tail nut 201 to move quickly along the light rod 204, thereby realizing instant opening of the door 101 and accelerating the opening speed of the door 101. Compared with the slow opening along the thread of the screw rod 202, the thread moving distance of the screw rod 202 is greatly shortened, thereby accelerating the speed of opening the door 101.

[0034] In the disclosed embodiment, the tail push ring 302 surrounds the outside of the light rod 204, and the light rod 204 and the main shaft of the driving motor 3 are fixed. When the main box body 1 is opened, the tail nut 201 and the screw rod 202 are separated, and the tail nut 201 and the tail push ring 302 are fitted together. The tail push ring 302 pushes the tail nut 201 to move to the screw rod 202. The driving motor 3 starts to drive the screw rod 202 to rotate, and the tail nut 201 moves axially along the thread of the screw rod 202 to realize the rapid closing operation of the box door 101. The thread movement distance of the screw rod 202 is greatly shortened, and the closing of the box door 101 is faster.

[0035] Embodiment 2, on the basis of embodiment 1, a plurality of bolt holes are set on the pushing ear plate 2 and fixedly connected with the tail nut 201. The tail nut 201 is adjusted in position by connecting with different bolt holes of the pushing ear plate 2. The distance of the tail nut 201 along the screw rod 202 is adjusted to achieve a faster switch to the situation where the gas spring telescopic cylinder 102 thrusts to open the box door 101. The push rod of the electromagnet 301 can also adjust the pushing distance according to the nut, and adjust the position according to the thrust of the gas spring telescopic cylinder 102.

[0036] The working principle of the first embodiment of the present invention is as follows: when the box door 101 needs to be opened, the electromagnet 301 is in the closed state, and the push rod of the electromagnet 301 is pushed to the other side by the spring, and the electromagnet 301 drives the tail push ring 302 to move away from the tail nut 201, and the drive motor 3 is started to drive the light rod 204 and the screw rod 202 to rotate synchronously, and the rotating screw rod 202 guides the axial movement of the tail nut 201 through the external thread, and the tail nut 201 and the pushing ear plate 2 move to open, and the tail nut 201 is disengaged from the screw 202 and moves to the light rod 204, and the thread of the screw 202 no longer locks the tail nut 201, and the box door 101 is in the open state, and the gas spring telescopic cylinder 102 is in the extended state, and the gas spring telescopic cylinder 102 continues to extend. The box door 101 is pushed, and the box door 101 and the door opening ear plate 103 are pushed by the gas spring telescopic cylinder 102 to continue to open. The door opening ear plate 103 pushes the push ear plate 2 and the tail nut 201 to move. The thrust of the gas spring telescopic cylinder 102 finally pushes the tail nut 201 to move quickly along the light rod 204, so that the box door 101 is opened instantly, and the opening speed of the box door 101 is accelerated. Compared with the slow opening along the thread of the screw rod 202, the thread moving distance of the screw rod 202 is greatly shortened, which further accelerates the speed of opening the box door 101, and at the same time reduces the reverse pressure of the pressure box door 101 on the screw rod 202, reduces the deformation of the thread of the screw rod 202, and reduces the wear or deformation of the screw rod 202;

[0037] When the door 101 needs to be closed, the electromagnet 301 is started, and the push rod of the electromagnet 301 moves under the magnetic force, and the push rod of the electromagnet 301 pushes the tail push ring 302, and the tail push ring 302 pushes the tail nut 201 to move to the screw rod 202, and the drive motor 3 is started to drive the screw rod 202 to rotate, and the tail nut 201 moves axially along the thread of the screw rod 202, so as to realize the fast closing operation of the door 101. Compared with the slow closing along the thread of the screw rod 202, the moving distance of the thread of the screw rod 202 is greatly shortened, and the closing speed of the door 101 is also faster;

[0038] The outer corrugated protective sleeve 205 covers the outside of the screw rod 202. The outer corrugated protective sleeve 205 stretches and compresses as the distance between the tail nut 201 and the limit plate 203 expands or contracts. The outer corrugated protective sleeve 205 covers the screw rod 202 inside. The outer corrugated protective sleeve 205 protects the screw rod 202 to prevent the screw rod 202 from being soaked in water and rusting, or dust from adhering to the thread and causing it to become stuck due to uneven thread movement. The outer protective cover body 104 also surrounds the telescopic rod of the gas spring telescopic cylinder 102 to protect it, thereby extending the service life of the screw rod 202. The outer protective cover body 104 reduces the possibility of dust adhering to the telescopic rod of the gas spring telescopic cylinder 102, thereby extending the service life of the gas spring telescopic cylinder 102.
