Description

Technical Field

[0001] This invention belongs to the field of sanitary ware, specifically a toilet exhaust device. Background Technology

[0002] Utility model patent ZL2023 23114815.6 discloses a novel exhaust toilet seat, but the air inlet is impractical in actual use, and one of the two exhaust vents is also idle. Such a toilet seat has a complex structure, high manufacturing cost, waste of manufacturing resources, and also brings unnecessary economic burden to consumers. In order to overcome the above defects, this invention discloses a new toilet exhaust device, which removes the impractical air inlet and one idle exhaust vent from the utility model patent ZL202323114815.6. Summary of the Invention

[0003] A toilet exhaust device comprises a toilet seat, an exhaust pipe, and an exhaust fan. The toilet seat has an intake hole on its inner side and an exhaust port on its outer side. All intake holes are connected to the exhaust port of the toilet seat. The exhaust fan is installed on a ventilation duct. One end of the exhaust pipe is connected to the exhaust port of the toilet seat, and the other end is connected to the intake port of the exhaust fan. When the exhaust fan is working, negative pressure is generated in the intake holes and exhaust pipe, forcibly drawing out the exhaust gas from the toilet and discharging it outdoors through the ventilation duct.

[0004] The beneficial effects of this invention are: preventing the spread of exhaust gas and pollution of indoor air; the exhaust gas device has a simple structure and is easy to manufacture, reducing waste in the manufacturing process and alleviating the economic burden on consumers. Attached Figure Description Figure 1 This is a structural view of the present invention; Parts Description

[0005] 1. Toilet seat, 2. Air intake, 3. Exhaust outlet, 4. Exhaust fan, 5. Exhaust pipe, 6. Air inlet.

[0006] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Specific embodiments Example 1, referring to Figure 1 Includes toilet seat 1, air intake 2, exhaust 3, exhaust fan 4, exhaust pipe 5, air inlet 6, such as Figure 1As shown, multiple air intake holes 2 are opened on the inner side of the toilet seat to absorb exhaust gas, and an exhaust port 3 is opened on the outer side of the toilet seat to discharge exhaust gas. All the air intake holes 2 are connected to the exhaust port 3 of the toilet seat 1. The exhaust port 3 is connected to one end of an exhaust pipe 5, and the other end of the exhaust pipe 5 is connected to the air inlet 6 of an exhaust fan 4. The exhaust fan 4 is fixedly installed on the building's ventilation duct, which is connected to the outdoor atmosphere. When the exhaust fan 4 is working, a negative pressure is generated in the air intake holes 2 and the exhaust pipe 5. Exhaust gas enters through the air intake holes 2, passes through the exhaust port 3 into the exhaust pipe 5, and then enters the exhaust fan 4. The exhaust fan 4 forcibly discharges the exhaust gas into the ventilation duct, from which it is discharged outdoors, thus preventing exhaust gas from entering the building. The purpose of gas diffusion; specific working process: the toilet seat 1 of the present invention is the same size and installation method as the ordinary toilet seat 1. First, the toilet seat 1 of the present invention is installed on the toilet. Then, the exhaust fan 4 is fixedly installed on the ventilation duct with ventilation holes. Then, one end of the exhaust pipe 5 is connected to the air outlet 3 of the toilet seat 1, and the other end of the exhaust pipe 5 is connected to the air inlet 6 of the exhaust fan 4. When a person sits on the toilet seat 1, a certain gap will be formed between the person and the toilet seat 1. Exhaust gas diffuses outward along the gap, polluting the environment. When the exhaust fan 4 is working, a negative pressure is generated in the pipe. Exhaust gas will enter the exhaust pipe 5 through the air inlet 2, and then be forcibly discharged into the ventilation duct by the exhaust fan 4. The exhaust gas is discharged outdoors through the ventilation duct. Example 2: The toilet seat ring and the toilet form an integral structure, constituting a venting toilet.

[0007] The above embodiments are preferred embodiments. No matter how the relevant technicians modify them, as long as the exhaust fan is used to extract the waste gas in the toilet through the pipe and discharge it to the outside, it is within the protection scope of this invention.
