Title: Improved odour extractor for toilets

Description:
FIELD OF THE INVENTION 
     The invention refers to a device that extracts bad odors, which is activated by an automatic sensor at the same time that the person sits on the bowl and for all the time that is using the toilet, which extracts these bad odors through the same holes through which the water will then come out at the time of discharging the tank, through a pipe that is installed for this purpose, transporting them to an external ventilation system preventing their spread in the bathroom and other rooms, and thereby the spread of bacteria, viruses, germs and others. 
     BACKGROUND 
     The generation of odors in the toilets of houses as well as public areas is a problem that is latent worldwide. A variety of solutions have been attempted and extracting devices have not been the exception. 
     There are several types of products in the market in general, which are used for similar functions than those described in this application. 
     There have been attempts for many years to solve the root problem, with new devices in the market, but despite their conformation and varieties, they have not succeeded in hitting the target concerning what the consumer would like as a complete solution. 
     There are now extractors commonly sold which, due to their design and shape, actually create a place conducive to the accumulation and spread of bacteria and germs, reason for which they do not really meet the complete removal goal. They contribute to the odor, but due to their operation, different from the one that will be described, they only contribute to the odor and not everything that it involves and contains. 
     Other factors that affect the current products are high cost and installation, as well as the access that certain social classes may have to it. 
    
    
     DETAILED DESCRIPTION 
     The development of this utility model was born out of the need to have a novel and hygienic product for the elimination of odors and to help remove bacteria, viruses, germs and other types of contaminating agents. At the same time, it is a device that is easy to install, economical to purchase and contributes to the environment. 
     Some advantages that this invention synthesizes, shows and develops on the premise of technology transfer are missing among the type of existing products in the state of the art. 
     It is a product designed to be used in a toilet, being the extraction done without allowing the minimum odor to emanate from the waste, and removing the vapors that make particles of such emanation to settle on that toilet bowl. 
     This invention is aimed at all types of existing toilets and can be installed in a simple and practical way. 
     This invention consists of an extractor that is composed of an air extractor or turbine, an air duct, an air outlet pipe and water supply, pipe, and an overflow siphon. 
     The turbine is the component that sucks the polluted air out leading it to the desired removal site. 
     The role of the air duct is to direct the polluted air from the toilet to the outlet pipe or duct. See  FIG. 1 . 
     The Air Outlet and Water Supply Tube removes the contaminated air and supplies water to the tank or cistern. Its design allows us to use the ONLY orifice available to remove the air and at the same time to insert the water to the toilet load system. This piece is fundamental in the inventive step that this improved device provides, since there is no other device for these purposes which performs this dynamic in the same piece. See  FIG. 2 . 
     The overflow pipe and siphon are a component that first performs the extraction of the polluted air from the toilet bowl using the same water flush pipes, and at the same time serves as an overflow device preventing the water from spilling out of the tank or cistern when the pump fails. Its siphon design ensures that the air extracted is directly from the toilet bowl and not from the tank or cistern. See  FIG. 3 . 
     As obvious improvements of this product, it complies with all health regulations to prevent the spread of viruses, germs and others, because when discharging the water, it automatically cleans the ducts through which in turn extracts all the contaminated air, thus avoiding the accumulation of these agents. It is very important to emphasize that the extraction has a movement sensor that has been modified in order that it gets activated only during the use of the toilet, helping with the comfort and tranquility of knowing that once the toilet is not being used, the extractor will automatically disconnect. 
     The cost of marketing and reaching the target consumer is low, compared to other extractors that exist in the global market. The device also has an easy-to-understand installation manual for the consumer. 
     It provides the user with peace of mind and security, because the user knows that each discharge cleans the exhaust ducts. It avoids in a high percentage the possible infection by viruses like diarrhea or others that may cause disease and that are proven to arise due to lack of hygiene in toilets.
