[0030] 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.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a handheld solar greenhouse ventilation electric switch device, including a base 1, which can be fixed to the wall by bolts to install and fix the shell 2. The front outer wall of the base 1 is fixedly connected with the shell 2. The shell 2 is the main body of the solar greenhouse ventilation window electric switch, which is made of lightweight alloy material and is light in weight. The operator does not need to manually pull the chain 5 to adjust the opening and closing of the top window, which is easy to operate. A battery compartment 9 is provided on the inner wall of the shell 2. The battery compartment 9 is provided on the left side wall of the shell 2, and a rechargeable battery is built in to provide power for the rotation of the motor 7. The inner wall of the shell 2 is fixedly connected with a sensor 8. When the chain 5 is pulled to a preset position or encounters abnormal resistance, it can automatically stop through the sensor 8 to protect the equipment and the greenhouse structure.

[0032] Reference Figure 1-Figure 3 A button 6 is fixedly connected to the front end outer wall of the shell 2, and the opening and closing of the top window can be automatically adjusted by pressing the button 6. A transmission mechanism is provided on the inner wall of the shell 2, and the top window can be driven to open and close when the output shaft of the motor 7 and the sprocket 4 rotate. A protective mechanism 3 is provided on the front end outer wall of the base 1, and the button 6 can be protected by the protective mechanism 3 to prevent accidental touch from affecting the opening and closing of the top ventilation window.

[0033] Reference Figure 2The protection mechanism 3 includes a bottom plate 301, which is fixedly connected to the front end outer wall of the base 1, and the bottom plate 301 is arranged below the shell 2. The front end inner wall of the bottom plate 301 is rotatably connected with a rotating shaft 306. The rotating shaft 306 can rotate in the inner wall of the bottom plate 301 to drive the baffle 307 to flip. The inner wall of the rotating shaft 306 is provided with a socket 305, and the socket 305 corresponds to the pull rod 303. The outer wall of the socket 305 is provided with two groups of grooves. The setting of the two groups of grooves can be fixed after the baffle 307 is opened or closed.

[0034] Reference Figure 2 The protrusion 304 is engaged with the groove, so that the rotating shaft 306 can be limited and the position of the baffle 307 can be fixed. The outer wall of the rotating shaft 306 is fixedly connected with the baffle 307. The bottom plate 301 contacts the outer wall of the baffle 307. The baffle 307 is concave in shape. When flipped to a vertical state, the button 6 can be protected. When flipped to a horizontal state, the button 6 can be opened for use, or the inside of the shell 2 can be maintained. The maintenance tools can be placed on the baffle 307.

[0035] Reference Figure 2 The inner wall of the bottom plate 301 is elastically connected to the pull rod 303 through the spring 302, and the pull rod 303 passes through the outer wall of the bottom plate 301. When not affected by external force, the spring 302 drives the pull rod 303 to always be plugged into the socket 305 due to its own elastic force. One end of the spring 302 is fixedly connected to the outer wall of the pull rod 303, and the other end of the spring 302 is fixedly connected to the inner wall of the bottom plate 301. When the pull rod 303 is pulled outward, the spring 302 is forced to contract, and the pull rod 303 is out of contact with the socket 305.

[0036] Reference Figure 2 The outer wall of the pull rod 303 is slidably connected to the inner wall of the base plate 301, and the pull rod 303 is plugged into the socket 305. The pull rod 303 can only move horizontally in the inner wall of the base plate 301, but cannot rotate. The outer wall of the pull rod 303 is fixedly connected with a protrusion 304. When the pull rod 303 is plugged into the socket 305, the protrusion 304 is engaged with the groove on the outer wall of the socket 305, so as to limit the baffle 307.

[0037] Reference Figure 3The transmission mechanism includes a motor 7, which is fixedly connected to the inner wall of the shell 2. The rechargeable battery in the battery compartment 9 can provide power for the motor 7 to rotate. The motor 7 can be started by pressing the button 6. The output shaft of the motor 7 is fixedly connected to the sprocket 4, and the sprocket 4 is rotatably connected to the front end outer wall of the shell 2. When the motor 7 is started, the output shaft rotates and drives the sprocket 4 to rotate. A chain 5 is arranged around the outer wall of the sprocket 4, and the other end of the chain 5 is connected to the rotating device of the ventilation window. When the sprocket 4 rotates, the rotating device of the ventilation window can be driven to rotate through the chain 5, thereby controlling the opening and closing of the ventilation window. This process is a prior art, but the prior art requires the operator to manually rotate the sprocket 4 to control the opening and closing. The device adopts an electric method, which reduces the work intensity of the operator and the opening and closing process is faster.

[0038] Working principle: when it is necessary to open and close the ventilation window at the top of the greenhouse, the pull rod 303 can be pulled outward to disengage the pull rod 303 from the socket 305 and the protrusion 304 from the groove, so that the limit of the baffle 307 can be released and the baffle 307 can be flipped downward. When it is flipped to a horizontal state, the pull rod 303 is released. Due to the elastic force of the spring 302 itself, the pull rod 303 rebounds and resets, and the protrusion 304 engages with another set of grooves to limit the baffle 307. At this time, the operator can start the motor 7 by pressing the button 6, so that the output shaft of the motor 7 drives the sprocket 4 to rotate, and the rotating device on the ventilation window is driven to rotate through the chain 5 transmission, so that the ventilation window can be opened or closed. The operator does not need to manually rotate the sprocket 4 to open or close the ventilation window, which is more convenient and quick, and also improves the efficiency and accuracy of the ventilation window opening and closing operation.

[0039] During the rotation of the sprocket 4, when the chain 5 rotates to the preset position or encounters abnormal resistance, the sensor 8 can automatically stop the motor 7 to protect the equipment and the greenhouse structure. When use is completed, the pull rod 303 can be pulled out, the baffle 307 can be flipped upward to reset, and the position of the baffle 307 can be fixed by engaging the protrusion 304 with the groove to protect the button 6 to prevent the operator from accidentally touching it and affecting the opening and closing angle of the ventilation window. The rechargeable battery in the battery compartment 9 can be replaced by flipping the baffle 307 downward to a horizontal state. At the same time, when repairing the inside of the shell 2, the operator can place the repair tools on the baffle 307 for easier access.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
