Detailed Description
In order to make the public fully aware of the technical spirit and advantageous effects of the present invention, the applicant shall describe in detail the embodiments of the present invention with reference to the accompanying drawings, but the description of the embodiments is not limited by the applicant, and any changes made according to the present invention but not essential should be construed as the protection scope of the present invention.
The utility model provides a public toilet new trend system, as shown in figure 1, including exhaust fan 1, air inlet machine 2 and infrared ray human body inductive switch 3, exhaust fan 1 and air inlet machine 2's one end is connected with electrical power generating system 8 after connecting in parallel, the other end is connected with infrared ray human body inductive switch 3 after connecting in parallel, infrared ray human body inductive switch 3 controls exhaust fan 1 and air inlet machine 2's start and stop through responding to human body pyroelectric infrared signal; the exhaust fan 1 and the air inlet fan 2 both adopt a new refrigerant R410A refrigerant to perform cooling in summer and heating in winter.
Preferably, the exhaust fan 1, the air inlet fan 2 and the infrared human body induction switch 3 are all arranged on a back wall 6 of the functional equipment 5 in each partition/partition plate 4 of the public toilet.
The functional equipment 5 comprises a pit, a toilet bowl and a urinal.
Preferably, in each partition/partition plate 4, the air volume of the exhaust fan 1 is the same as that of the air inlet fan 2, and the air volume is 20-200 cubic meters per hour; the vertical distance H between the exhaust fan 1 and the air inlet fan 2 and the ground is the same, and the horizontal distance between the exhaust fan 1 and the air inlet fan 2 and the vertical center line of the functional device 5 is also the same, namely the exhaust fan 1 and the air inlet fan 2 are equal in height to the ground and symmetrically arranged on the left side and the right side of the back of the functional device 5, and the air volume is the same, so that when a person goes to the toilet, the infrared human body induction switch 3 can ensure that the exhaust fan 1 and the air inlet fan 2 are started simultaneously, air enters one by one near an odor source, and small-cycle balanced ventilation is formed; after the person leaves, the infrared human body induction switch 3 is closed, and the exhaust fan 1 and the air inlet fan 2 stop at the same time. If the air volume of the exhaust fan 1 and the air inlet fan 2 is different, or the air volume is not symmetrically arranged on the left side and the right side of the back of the functional equipment 5, the air supply and the air exhaust of the air inlet fan 2 and the exhaust fan 1 are not matched, and small circulation balance ventilation can not be formed near an odor source; or because the requirements of the air volume and the distance size cannot be met, the distance is too far and the air volume is too weak, the air sent by the air inlet fan 2 is pumped and discharged by the exhaust fan 1 when the air does not reach the odor source position, an air flow short circuit is formed, and the deodorization function cannot be achieved.
