The utility model discloses a fruit and vegetable fresh-keeping storehouse with self -cleaning function, including the frame body that a plurality of stand columns enclose and form, a plurality of height adjustable support assemblies are arranged in layers in the frame body, the clearance for sundries falling is between the support assembly, is provided with the drainage groove board in the frame body bottom, the side of drainage groove board is provided with the drain pipe and the air pipe. This fruit and vegetable fresh-keeping storehouse sets up the shape of goods shelf reasonably, so as to be convenient for placing fruit and vegetable, and the sundries and water stain of its residue can automatically fall into the drainage groove board below after fruit and vegetable, which are automatically discharged through the drain pipe and the air pipe, realize the self -cleaning of goods shelf, and the subsequent fruit and vegetable placement is convenient.

The application discloses a respiratory tract unblocking device for a respiratory system, which comprises a breathing nozzle, a three-way pipe, an adjusting pile, a gas distribution pipe and a water storage bottle. The three-way pipe is rotationally connected with the adjusting pile at the top, fixedly connected with the breathing nozzle at the middle and fixedly connected with the water storage bottle at the bottom. The gas distribution pipe is linearly slidably connected with the water storage bottle and threadedly connected with the adjusting pile. The water storage bottle contains liquid. When a patient needs to unblock sputum, the patient only needs to exhale into the device through the breathing nozzle, so that continuous air bubbles are formed at the bottom of the water. In this process, the positive pressure exhalation can prevent the end of the airway of the patient from collapsing too early. Since the air bubbles are generated one by one, the airway can be shaken in the reverse direction. In addition, the exhalation flow rate can be accelerated, and finally the patient can better unblock the secretion in the airway.

The utility model discloses a pressure relief cushion, and relates to the technical field of cushions, the pressure relief cushion comprises a first layer, a second layer and a third layer, the first layer is provided with an adjusting area, the adjusting area is configured to be of a hollow structure, the adjusting area is provided with a plurality of first cavities, and the first cavities are used for adjusting the pressure received by the pressure relief cushion; when the first cavity is pressed, the first cavity deforms, and when the first cavity is released from pressing, the first cavity recovers to deform. According to the technical scheme provided by the utility model, the problems that the pressure of buttocks and thighs cannot be well adjusted and the ventilation effect is poor in an existing cushion can be solved.

The utility model provides a high-air-permeability uneasy-to-fall plaster patch which comprises a protective layer, the bottom end of the protective layer is fixedly connected with an isolating layer, the bottom end of the isolating layer is fixedly connected with an air-permeable layer, the bottom end of the air-permeable layer is fixedly connected with a medicine pad, the bottom end of the medicine pad is fixedly connected with a limiting ring, and the limiting ring is fixedly connected with the bottom end of the medicine pad. The bottom end of the medicine pad is fixedly connected with a tablet, and the bottom end of the tablet is fixedly connected with a fixing layer. According to the utility model, the problem of insufficient air permeability of the plaster patch is effectively solved. The air circulation condition in the plaster is improved, the skin can still keep the normal breathing state in the long-time pasting process of the plaster, the problems of stuffiness, itching and other uncomfortable reactions of the skin due to poor air permeability are solved, meanwhile, the good air permeability creates an ideal environment for the skin to absorb medicine, and the skin can be effectively protected. The speed that the medicine permeates into the deep layer of the skin is accelerated, and the use experience and the treatment effect of the plaster patch are improved.

The utility model discloses a kind of cultivation frames, it is related to planting equipment technical field, including frame body, first cultivation frame is installed in frame body inner wall top, two second cultivation frames are slidably arranged in frame body inner wall bottom, two second cultivation frames are evenly arranged in frame body inner wall with first cultivation frame, two first sliding grooves are opened in frame body inner wall middle part, two second sliding grooves are opened in frame body inner wall bottom, first rack is slidably connected in first sliding groove inside, second rack is slidably connected in second sliding groove inside.In the utility model, when second cultivation frame can be pulled out from frame body, first cultivation frame and two second cultivation frames are ladder-shaped distribution, reduce the problem of light shielding, improve the efficiency of crop photosynthesis, also facilitate user to pick crop, and in the second cultivation frame removal frame body, the cooperation of component can also open fan, accelerate air circulation in frame body inside and on second cultivation frame, improve ventilation environment, reduce the occurrence of disease.
