DETAILED DESCRIPTION OF THE INVENTION

[0040] A detailed description of the invention is given with reference drawings and specific embodiments of the invention as follows.

[0041] As is shown in FIG. 1, equipment for elastic glove airtightness-detecting and rapid-donning equipment with a sterilization function of the invention comprises two sterilization cavities 1 internally provided with sterilization devices, sleeve fixing rings 3 for elastic gloves 2, connecting air pipelines 4, a two-way air pump 5, ozone generation pieces 6, pressure detection switches 7, electromagnetic valves 8, flow regulating valves 9, one-way valves 10, sterilizing filters 11, control loops 12, a control cabinet 13 and a pedal switch 14. Through holes used for mounting the sleeve fixing rings 3 for the elastic gloves 2 are formed in one side of the sterilization cavities 1; fingerstall sections of the gloves 2 are located inside the sterilization cavities 1, the sleeve ends are fixed to the sterilization cavities 1 through the sleeve fixing rings 3, and the elastic gloves 2 can be donned rapidly under control action; the two sides of the bottom of each sterilization cavity 1 are provided with air pipeline ports 17 which are connected with the two-way air pump 5 serving as an air source, and the small-power ozone generation pieces which serve as the sterilization devices 6 and the pressure detection switches 7 which are used for detecting the internal pressure of the sterilization cavities 1 and used for closed-loop control are also mounted; the small-power ozone generation pieces serve as the internal sterilization devices and are safe, efficient and harmless to human bodies. The air pipelines 4 are provided with the electromagnetic valves 8, the flow regulating valves 9, the one-way valves 10 and the sterilizing filters 11, and are connected to the sterilization cavities 1 and the two-way air pump 5; the air pipelines 4 can be used for controlling the directions and flow rates for air flow in the sterilization cavities 1 and used for sterilizing and filtering.

[0042] A module used for action control comprises the control loops 12, the control cabinet 13 and the pedal switch 14. The pedal switch 14 and the pressure detection switches 7 are used for action control and closed-loop control, and manual touch control is not needed.

[0043] When the elastic gloves 2 are fixedly mounted on the sleeve fixing rings 3 of the sterilization cavities 1, the cavity through holes are airtight relative to the outside, and elastic deformation of the elastic gloves 2 can be caused by the change of the internal pressure of the cavities. The elastic gloves 2 are made to stretch by means of negative pressure (lower than the standard atmospheric pressure) in the sterilization cavities 1 and thus can be donned easily; when the completeness of the gloves is broken, automatic checking can be conducted through the internal pressure states of the sterilization cavities 1 and the stretching states of the gloves. The elastic gloves 2 are made to contract by means of positive pressure (higher than the standard atmospheric pressure) in the sterilization cavities 1 and thus can be donned rapidly.

[0044] As is shown in FIG. 2, the sterilization cavities used for donning the elastic gloves of the invention structurally comprise the cavity through holes 15, the fixing rings 3, the cavity shells 16 and the air pipeline ports 17. When the elastic gloves to be donned are fixedly mounted on the fixing rings 3, the cavity through holes 15 are airtight relative to the outside; the internal pressure of the cavities can be changed through air flow in the air pipeline ports 17, and elastic deformation of the elastic gloves mounted on the fixing rings 3 is caused accordingly; when the elastic deformation reaches a certain degree, the elastic gloves can be donned conveniently and released automatically after being donned.

[0045] The operating principle of the invention is shown in FIG. 1 and FIG. 3, donning operation is started through the pedal switch 14, and when the internal pressure of the sterilization cavities 1 does not reach the detection threshold value of the pressure detection switches 7, the states of the pipelines are shown by the negative pressure generation part in FIG. 3. At the moment, an air inlet of the two-way air pump 5 is connected with ports A of the two electromagnetic valves 8 and communicates with air outlets of the sterilization cavities 1 through the air pipelines 4, and an air outlet of the two-way air pump 5 is connected with ports B of the two electromagnetic valves 8 and communicates with the outside atmosphere, so that air suction cycles are formed, the pressure in the two sterilization cavities 1 is decreased, and accordingly the elastic gloves 2 are stretched conveniently to be donned. If the elastic gloves 2 are broken at the moment, breakage of the elastic gloves 2 can be checked out automatically through readings on the pressure detection switches 7 and the stretching states of the gloves. When the system is not started through the pedal switch 14, or the pressure detection switches 7 detect that the pressure in the sterilization cavities 1 reaches a certain threshold value, an on-off control signal is output, and the sterilization cavities 1 and the air pipelines 4 are in or switched to a balanced pressure state shown by the balanced pressure part in FIG. 3. The air inlet and the air outlet of the two-way air pump 5 are connected with channels of the electromagnetic valves 8 and both communicate with the outside atmosphere, the air inlets and the air outlets of the sterilization cavities 1 on the left side and the right side are sealed, and the internal air pressure of the cavities can be maintained under a good sealing condition and is equal to the outside air pressure when the cavity through holes are opened. When the wearer treads on the pedal switch 14 on the other side and the internal pressure of the sterilization cavities 1 does not reach the detection threshold value of the pressure detection switches 7, the states of the pipelines is shown by the positive pressure generation part in FIG. 3. The air outlet of the two-way air pump 5 is connected with the ports B of the two electromagnetic valves 8 and communicates with the air inlets of the sterilization cavities 1, and the air inlet of the two-way air pump 5 is connected with the ports A of the electromagnetic valves 8 and communicates with the outside atmosphere, so that air inflation cycles are formed, the pressure in the two cavities is increased, and accordingly the elastic gloves 2 are contracted to be donned.

[0046] The small-power ozone generation pieces 6 are used for sterilization in the sterilization cavities 1, safety is guaranteed, and the efficiency is high; the sterilizing filters 11 are mounted on the air pipelines 4 to guarantee the cleanliness of air flow entering and coming out of the cavities, the air flow can be regulated through the flow regulating valves 9 and the one-way valves 10, and working index requirements are met.

[0047] For further guaranteeing that the gloves are donned conveniently through the equipment of the invention, the cross sections of the cavity through holes can be of a round or quasi-round structure (shown in FIG. 4), or of an oval or quasi-oval structure (shown in FIG. 5), or of an egg-shaped or quasi-egg-shaped structure with the upper section being sharp and the lower section being obtuse (shown in FIG. 6).

[0048] Of course, for donning the gloves conveniently, the following transformation schemes can also be adopted for the cavity through holes:

[0049] (1) the scheme where the radius increment of the outer edges is changed (shown in FIG. 10): the radius increment of the opening edges of the cavity through holes is decreased from top to bottom, the radius increment of the upper portions of the opening edges is large so that mounting can be convenient, and the radius increment of the lower portions of the opening edges is small so that dismounting is convenient. In other words, the opening edges of the cavity through holes extend upwards and downwards from one end of the cavity through holes, however, the opening edges extend upwards and downwards by different dimensions, specifically, the upward extension dimension of the opening edges from the center is larger than the downward extension dimension of the opening edges from the center so that after the gloves are placed in the sterilization cavities, the free ends of the gloves can be turned out to be fixedly mounted on the opening edges conveniently, and the gloves can be released easily;

[0050] (2) the scheme where the outer edges are changed into a bevel shape from a step shape (shown in FIG. 11): the tops of the opening edges of the cavity through holes are in the step shape, and the opening edges are smoothly changed to be in the bevel shape downwards. The tops of the opening edges are in the right-angled step shape so that mounting can be convenient, and the bottoms of the opening edges are in the bevel shape so that dismounting can be easy. In other words, the opening edges of the cavity through holes extend upwards and downwards from one end of the cavity through holes, however, the upward extension parts of the opening edges are designed to be right-angled, and the downward extension parts of the opening edges are designed to be bevel;

[0051] (3) the scheme where the outer edges are of a stretchable mode (shown in FIG. 12a and FIG. 12b): movable cavity through holes are adopted; in one embodiment of the invention, the opening edges are made of elastic materials, and elastic pieces are arranged between the opening edges and the cavity through holes; when the gloves are about to be mounted in the cavity through holes, the opening edges move towards the interiors of the cavity through holes under the effect of external force, the elastic pieces are stretched at the same time, the cavity through holes contract, the calibers are decreased, and the gloves can be mounted conveniently; after the gloves are mounted, the external force disappears, the opening edges restore to the original state under the effect of the elastic pieces, the calibers are restored at the same time, and the gloves are well fixed. The gloves are donned after being expanded under negative pressure, then balanced pressure and positive pressure are achieved, and after the positive pressure reaches a certain pressure value, the cavity through holes contract again for releasing the gloves easily.

[0052] For mounting the gloves more conveniently and releasing the gloves more easily, movable buckle devices (shown in FIG. 13a, FIG. 13b and FIG. 13c) are arranged in the positions, close to the opening edges, of the outer walls of the cavity through holes; when the gloves are mounted, buckles contract, and oversleeves are fixed through the buckles; before vacuumizing for negative pressure, the buckles bounce to well fix the gloves; after the gloves are donned, inflation is conducted for positive pressure, the buckles contract again, and the gloves.

[0053] The outer edges of the cavity through holes can also be of a horn-shaped structure or a step-shaped structure or a bevel-shaped structure; as is shown in FIG. 7, the horn shape refers to that the radiuses of the opening edges of the cavity through holes are increased gradually, and the opening edges are in smooth bevel transition; as is shown in FIG. 8, the step shape refers to that the radiuses of the cavity through holes are increased, and the opening edges are in a right-angled step shape; as is shown in FIG. 9, the bevel shape refers to that the radiuses of the cavity through holes are increased gradually, the opening edges are in smooth bevel transition.

[0054] The equipment for elastic glove airtightness-detecting and rapid-donning with the sterilization function of the invention is simple and reasonable in structural design, the principle basis is sufficient, the technical scheme can be achieved easily, the equipment is safe, convenient to use and efficient, and the requirement for the sanitation condition in elastic glove donning operation can be fully met.
