[0005] From the above description, it can be seen that if the slats of the venetian blind are to be turned over at a certain angle to meet the lighting requirements of the room and to raise or lower the venetian blind as required, the user must move the aforementioned external controller upward or downward. To achieve this, the
operation mode brought about by this structure has become the default and accepted mode by the majority of users, but objectively, this
operation mode has at least the following technical problems: First, if the aforementioned internal and external manipulators are separated from each other by the inner glass There is a mismatch between the
suction force of the suction and the quality (weight) of the venetian blind located between the inner and outer glass. For example, if the
suction force is too small, abnormal sliding will occur and the venetian blind cannot be reliably maintained at the desired rising position , On the contrary, it will make the operation laborious and blindly increase the cost of the inner and outer manipulators, because increasing the number of relatively expensive permanent magnets and / or increasing the volume of the permanent magnets will inevitably increase the cost significantly; secondly, as long as In the case of manually shifting the outer
manipulator, it is relatively laborious, especially the larger the width of the venetian blind, the heavier the overall weight of the venetian blind, and the stronger the magnetic attraction force between the inner and outer manipulators. Strong, this is very embarrassing for the weak such as minors and the elderly; third, once the inner
manipulator is affected by sliding such as displacement, deformation, and stagnation, it will be quite troublesome to repair , it needs to be repaired by the manufacturer or the original installer or professionals, and the repair usually needs to remove the inner glass, which requires a large amount of work, a long time, and high
payment costs. It is precisely because of these factors that users are often unwilling to repair and instead Make do with it, making it a decoration or even a burden; Fourth, since it is necessary to provide a sliding channel for the inner
manipulator, it will affect the lighting area to a certain extent
[0006] Chinese Invention
Patent Application Publication No. CN110513023A recommends "Electric Rotary Magnetic Transmission Built-in Sunshade Insulating Glass" due to the use of an external magnetic transmission electric controller and a driven magnetic transmission part in the cavity, which can compensate the applicant to a certain extent. The deficiencies mentioned above, but this
patent application still has the following shortcoming: the one, because this patent has taught in the 0029th
paragraph of its description that special positioning grooves and ribs are set on the motor, so that the motor is positioned on the housing (patent It is called "shell seat"), so due to the relatively complicated structure of the motor, it is troublesome for both the manufacturer of the motor and the manufacturer of the hollow built-in blinds, and the complexity of the motor structure will increase the performance of the motor. The second is because it does not give the enlightenment of how to make the housing carry (that is, together with) the motor, non-
metal spacer and magnetic column installed in it and the inner glass of the hollow glass built-in shutter reasonably fixed under the use state, because Only relying on the magnetic force of the aforementioned magnetic column (i.e. the outer magnetic column) of the external magnetic transmission electric controller on the magnetic column (i.e. the inner magnetic column) corresponding to the
structural system of the driven magnetic transmission part in the cavity is not perfect. For example, once the external magnetic transmission controller is shifted or even falls off due to the
impact or collision of abnormal external factors, it will affect the re-matching effect of the two, especially for users, often resulting in unknown The third is that although the patent mentions the content of the
power cord connected to the power supply in
paragraph 0028 of the specification, it also does not give information on how to make the motor work, such as how to supply power to the motor, how to control the motor, and how to control the motor. Enlightenment on how to arrange the indispensable parts in the case along with the motor
