Problems solved by technology

[0002] Nowadays, automatic sliding doors are used more and more widely. In order to prevent insects such as mosquitoes from entering the house in some rural areas, people often install a screen door that needs to be slid by hand outside the automatic sliding door. The ventilation effect can achieve the effect of isolating mosquitoes, but this makes the function of the automatic sliding door a bit tasteless, because the screen door still needs to be opened and closed manually when people enter and exit. This device can realize the function of automatic door opening. On this basis A roll-up mosquito-proof gauze that is linked to the door is added, and the mosquito-proof gauze can be lowered after opening the door so that the house is not affected by mosquitoes and other insects, so it is necessary to design a door switch device

Abstract

The invention discloses a door opening and closing device. The door opening and closing device comprises a device body, an automatic door opening device arranged in the device body, an anti-mosquito device arranged in the device body and a locking device arranged in the device body. The automatic door opening device comprises a first cavity formed in the device body. The inner wall of the lower side of the first cavity is provided with a first groove with an upward opening. The inner wall of the right side of the first groove is internally and fixedly provided with a first motor. The right endof the first motor is connected with a rotatable first screw rod extending into the first groove in a power fit mode. The door opening and closing device can achieve the door automatic opening function. On this basis, a roller shutter type anti-mosquito gauze in linkage with door opening is additionally arranged. After a door is opened, the anti-mosquito gauze can be lowered down to protect the interior of a room against mosquitoes and other insects.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a door switch device. Background technique [0002] Nowadays, automatic sliding doors are used more and more widely, and in some places in the countryside, in order to prevent mosquitoes and other insects from entering the house, people often install a screen door that needs to be slid by hand outside the automatic sliding door, so that it can be achieved at ordinary times.
