The invention relates to a garbage can facilitating sleeving of a garbage bag. The garbage can comprises a can body. A plurality of holes are uniformly distributed in the can body in the circumferential direction. The upper side of each hole is provided with a conical convex block connected with the can body. The upper side of each hole is provided with the conical convex block connected with thecan body. N rows of holes are distributed in the axial direction of the can body. The holes are oval. An inverted conical slot is formed in the middle of each conical convex block. The left end and the right end of each inverted conical slot are provided with V-shaped slots formed in the radial direction of the can body. The four rows of V-shaped slots are distributed on the slot surfaces of the inverted conical slots. The garbage can is simple in structure and convenient and quick to operate. An opening of the garbage can can be fixed to the garbage can and can be prevented from being foldedand curled up so as to keep the garbage can clean and prevent garbage from contaminating people. Potential sanitary safety trouble can be avoided. The garbage bag and the garbage can are combined. Thegarbage can is attractive in appearance without extra materials and devices and is friendly to environment.

The invention discloses an automatic detection device of leakage rays in an X-ray protective system. The automatic detection device is composed of an automatic detection car and a remote system control console, wherein the automatic detection car is composed of a travelling drive wheel, a gear steering device, a lifting transmission device, a back and forth expansion device and an angular deflection device; a leakage ray automatic feedback detector, an automatic spraying marking device and a real-time monitoring camera are arranged on the automatic detection car; and the remote system controlconsole is composed of a personal computer (PC), a programmable logic controller (PLC), a motion controller, a servo driver, a position encoder, a signal acquisition feedback chip and a timely monitoring imaging chip and the like. The automatic detection device provided by the invention has high automation degree, can be used for carrying out real-time leakage ray detection on a protective shieldroom at any angle, and has the advantages of precision positioning, strong applicability and high detection precision and the like. The automatic detection device has the characteristic of high safety performance because the condition that personnel is subjected to ray safety damage by accident can be fundamentally avoided in the remote control automatic detection; and the automatic detection device can be widely applied in manufacture factories and use factories of X-ray instruments, and detection epidemic prevention departments of each ray.

The invention discloses an ashtray capable of preventing a kid from eating cigarette ash and cigarette ends by mistake. The ashtray comprises an ashtray base and a sealing cover plate, wherein a through hole, a cavity body and a clamping slot which are communicated with one another are formed in the ashtray base in sequence; a clamping block clamped with the clamping slot in a matched manner is arranged on the sealing cover plate; a limiting structure matched with the clamping block is arranged on the ashtray base; the limiting structure comprises a limiting ball, a limiting rod, a gear, a rack, a connection rod, an iron block, an electromagnet, a magnet, a protective cover, a supporting block and a button switch. According to the ashtray, the sealing cover plate can be taken out only by quickly pulling out the protective cover, but releasing of the button switch and pulling of the supporting block need to be carried out at the same time; if the releasing and the pulling are separately carried out, the sealing cover plate cannot be taken out; therefore, the problem on cleaning caused by the fact that the kid opens the ashtray and the potential health and safety hazard caused by mistaken eating are effectively prevented.

The present invention provides a touch monitoring method, device, and terminal, wherein the method includes: obtaining multiple touch operations performed by the user on the preset touch area of ​​the terminal within a preset time period; control operations to obtain attribute information corresponding to the touch operations; and prompt the user according to the attribute information of the plurality of touch operations. The device includes: an operation acquisition module, an attribute acquisition module and a prompt module. The present invention can promptly remind users of excessive use of terminals, and effectively avoid potential health and safety hazards caused by excessive use of terminals to users.

The invention relates to a hyperbranched polyester-modified polyurethane medical interventional catheter and a manufacturing method thereof. A catheter body of the catheter is made from a mixed fused material of hyperbranched polyester which contains carboxyl groups and palmitate groups in end groups thereof and a thermoplastic polyurethane elastomer, wherein a hydrophilic coating, which is in covalent bond connection to the catheter, is coated on the outer surface of the catheter; and the hydrophilic coating includes a bottom coating, which can be grated with the outer surface of the catheter, and a top coating which forms a semi-interpenetrating network structure with the bottom coating. According to the medical interventional catheter and the manufacturing method thereof disclosed by the invention, on the basis of the property that the hyperbranched polyester has a great amount of the end groups, and in combination with a chemical bond grating technology between the catheter and the coating as well as a semi-interpenetrating network construction technology between a hydrophilic polymer and the coating, the catheter and the coating are closely combined effectively, so that the manufactured polyurethane medical interventional catheter is excellent in lubricating property and abrasion resistance; and the catheter is applicable to the field of endovascular intervention diagnosis and treatment.

The invention relates to a non-glue whole-bamboo chopping board which comprises a chopping board main body formed by overlaying at least two whole-bamboo sheet bars. The side part of the chopping board main body is provided with a group of clamping parts for clamping and fixing the overlaid whole-bamboo sheet bars. The non-glue whole-bamboo chopping board has a reasonable and compact structure; by arranging the chopping board main body formed by overlaying the at least two whole-bamboo sheet bars and mounting and arranging the one group of clamping parts for clamping and fixing the overlaid whole-bamboo sheet bars at the side part of the chopping board main body, the real whole-bamboo non-glue processing production of the chopping board is realized and potential sanitation and safety hazards of an existing chopping board are avoided; under the condition of ensuring anti-cutting and anti-striking intensity of the chopping board main body, the area for chopping is enlarged; compared with the existing chopping board, the chopping board in the scheme has obvious effects of resisting to heat, resisting to pressure and resisting to deformation. The non-glue whole-bamboo chopping board is reasonable in cost and safe, has a good use effect and is worth being popularized.
