Keywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.

Air sterilizing method for elevator and elevator sterilizer
Description
translated from
Technical field
The present invention relates to air disinfection and purification equipment, specifically is a kind of method and elevator sterilizing machine that air in the elevator is carried out sterilizing.
Background technology
Acceleration along with world industryization, air pollution problems inherent is more and more serious, after particularly the SARS epidemic situation taking place this year, air pollution and water pollute and were once causing people's fear, this brings very big harm for people's physical and mental health, how to solve the important topic that water cleaning and air cleaner problem become current environment specialist.
In built-up big city, elevator has become one of important vehicles, and particularly in the many places of mobile personnel such as hospital, office building, the utilization rate of elevator is higher, if not often sterilization in the elevator will become the place that pathogenic bacteria grows and propagates.
At present, though production marketings such as existing air cleaner, air sterillization sterilization machines, these products are mostly only considered to be not suitable for the place use that the space is bigger using in elevator.Up to the present, adopt ozone disinfecting technology device of sterilizing in elevator not see that relevant document discloses.
Summary of the invention
In order to overcome the prior art above shortcomings, the invention provides a kind of method and elevator sterilizing machine that adopts ozone air in the elevator to be carried out sterilizing.
The present invention adopts ozone that the method that air in the elevator carries out sterilizing is comprised the steps:
Shutter is opened in a, the fan that starts decontaminating apparatus, ozonator and the work of infrared remote sensing head;
B, infrared remote sensing head output signal trigger control circuit when the passenger is arranged are closed ozonator, and fan is blown in elevator;
C, when no passenger, make ozonator work, fan is sent ozone-containing air and is killed antibacterial and virus in the elevator in elevator;
D, if infrared remote sensing head when having sensed the passenger once more, the corresponding operating of above-mentioned b, c step is carried out in circulation.
Realize the elevator sterilizing machine of above-mentioned sterilizing method, comprise casing 1, casing 1 antetheca is provided with shutter 2, an infrared remote sensing head 3 is installed on shutter 2 next doors, casing 1 inner chamber is equipped with fan 4, between fan 4 and the shutter 2 ozonator is installed, described casing 1 inner chamber also is equipped with control circuit board, and ozonator, fan 4, infrared remote sensing head 3 and shutter 2 are connected with the corresponding terminal of control circuit board respectively.
The present invention adopts ozone that air in the elevator is carried out sterilizing, and killing pathogenic bacteria purifies the air in the elevator at short notice, has avoided secondary pollution.Its elevator sterilizing machine design has the infrared remote sensing head, and when having no talent in the elevator, sterilizing machine carries out disinfection automatically, has man-hour to stop sterilization, and fan is blown in elevator.This elevator sterilizing machine has been filled up the blank that elevator does not have sterilizing equipment decontaminating apparatus, is the ideal equipment that prevents that SARS and acute infectious disease from propagating, and can be widely used in all kinds of elevators sterilization and using.
Description of drawings
Fig. 1 a, b are exemplary embodiments structural representation of the present invention;
Fig. 2 is its control circuit embodiment schematic diagram.
The specific embodiment
Further specify below in conjunction with accompanying drawing.
Embodiment illustrated in fig. 1 is a KED-A38 elevator sterilizing machine, this machine comprises casing 1, casing 1 antetheca is provided with shutter 2, an infrared remote sensing head 3 is installed on shutter 2 next doors, casing 1 inner chamber is equipped with fan 4, between fan 4 and the shutter 2 ozonator is installed, described casing 1 inner chamber also is equipped with control circuit board, and ozonator, fan 4, infrared remote sensing head 3 and shutter 2 are connected with the corresponding terminal of control circuit board respectively.
This elevator sterilizing machine is provided with power line outlet 5 at the lower left quarter of casing 1, and the power line that this mouthful drawn is received on the 220V power supply and got final product work.
As shown in Figure 2, control circuit of the present invention comprises infrared remote sensing head 3, power circuit, relay K 1 and the diode D1 that is parallel to its coil two ends, infrared remote sensing head 3 is an infra-red sensor switch, it is external in binding post J1, and relay K 1 is connected between the lead-out terminal and power end of infra-red sensor switch.Relay K 1 is used for controlling the startup of ozonator/stop, and fan 4 and shutter 2 connect power supply.Power circuit comprises the resistance-capacitance depressurization circuit that rectifier bridge heap, Zener diode D2, filter capacitor C2 and R1C1 form.
Adopt this elevator sterilizing machine as follows to the process that air in the elevator carries out sterilizing:
This machine adopts infrared remote sensing to control, and after the energized, fan 4 enters duty immediately with ozonator, and shutter 2 is opened; When the passenger had been sensed in infrared ray remote sensing 3, ozonator quit work immediately, and fan 4 is blown in elevator by shutter 2; When infrared ray remote sensing 3 is sensed in the elevator nobody, ozonator was started working after time-delay a period of time, fan is sent ozone-containing air in elevator, kill antibacterial and virus in the elevator rapidly, purify air in the elevator, to prevent growing and propagating of pathogenic bacteria, described ozone-containing air also is to discharge from the shutter of the casing of decontaminating apparatus; When if the infrared remote sensing head has been sensed the passenger once more, above-mentioned corresponding operating is carried out in circulation.When night nobody the time, can close this electromechanics source and quit work.
Below in conjunction with disinfection principle this KED-A38 elevator sterilizing machine is explained as follows:
Human ozone discovered that ozone has unstability and very strong oxidability.Ozone is by an oxygen molecule (O
2) carry an oxygen atom (O) composition, it is the allotrope of oxygen.Because ozone O
3Be by an oxygen molecule (O
2) carry an oxygen atom (O) and form, determined that it is a kind of temporary form, the oxygen atom that carries except that oxidation is used up, the remaining oxygen (O that is combined into again
2) enter steady statue.So do not have problem of secondary pollution in the ozone work, the prime advantage of Here it is ozone technology.
The application of ozone is mainly at artificial sterilization.Mainly be that ozone has very strong oxidability, the cell wall that oxygen atom can oxidizing bacteria is captured the life of antibacterial until penetration cell wall unsaturated bond chemical combination intravital with it.Its effect is finished at once, has the broad-spectrum sterilization effect.KED-A38 elevator sterilizing machine ozone technology has extremely strong disinfecting and sterilizing functions.Its bactericidal effect satisfies the requirement in the elevator fully.
