The utility model discloses a hot air comb convenient to carry and store, and belongs to the technical field of personal care appliances. Comprising a handle and an air outlet cylinder, and a self-rotating structure is arranged between the handle and the air outlet cylinder to enable the air outlet cylinder to rotate relative to the handle and be overlapped; the other end of the air outlet cylinder is connected with the anti-scalding comb head through a buckle assembly. The self-rotating structure comprises a rotating part, a sliding piece and the like, locking is achieved through clamping of a locking protruding column and an auxiliary clamping hole, and the jacking assembly is used for unlocking. The anti-scald comb head comprises a three-dimensional annular brush comb head and a single-face brush comb head, the three-dimensional annular brush comb head is convenient to operate and far away from a heat source due to the rotary handle design, and the single-face brush comb head divides a cavity to guide airflow. The wedge-shaped clamping block of the buckle assembly is matched with the L-shaped locking groove to achieve rapid disassembly and assembly of the comb head. The handle is connected with a power line through a quick-plug structure, and 360-degree circumferential rotation sliding electrification is supported. The problems that a traditional hot air comb is inconvenient to fold, the comb head is inconvenient to replace, and the anti-scalding effect is insufficient are solved, and the multifunctional hot air comb has the advantages of being convenient to store, convenient to replace the comb head and safe in anti-scalding effect due to the separated power line design.

The utility model relates to a vertical plug-in type disk device, and aims to solve the technical problems that the weight of the conventional disk device is inconvenient to adjust and the use flexibility is low. The dumbbell piece device comprises a handle, dumbbell pieces and a knob with a limiting rod. Fixing pieces are arranged at the two ends of the handle, and the fixing pieces and the handle form a longitudinal insertion channel through a through hole structure; a through hole and a mounting groove are formed in the center of each disk, longitudinal positioning is achieved through matching of the limiting rod and the through hole, and transverse locking is completed by means of width matching of the limiting face of the knob and the mounting groove. An elastic clamping structure is arranged in the knob, and the positioning protrusions and the positioning holes of the dumbbell pieces are driven by the button to form secondary locking, so that the use stability is ensured. According to the scheme, tool-free quick disassembly and assembly of the dumbbell pieces are supported, multi-gradient weight adjustment is provided, meanwhile, the safety and the operation efficiency are remarkably improved through longitudinal insertion and a double-locking mechanism, and the device is suitable for high-strength training scenes.

This utility model discloses a self-cleaning honeycomb dust collector device, relating to the technical field of air filtration devices. It includes a fixed shell, an air inlet pipe fixedly connected to the upper surface of the fixed shell, a purification shell fixedly connected to the inner cavity of the fixed shell, an exhaust pipe fixedly connected to the left side of the purification shell, and the outer wall of the exhaust pipe fixedly connected to the inner cavity of the left part of the fixed shell. Three filter components are fixedly installed in the inner cavity of the purification shell. The self-cleaning honeycomb dust collector device of this utility model, by rotating a first rotating wheel, allows the mounting base to push the filter screen barrel to rotate and move into the inner wall of the annular support mesh cylinder. Through the action of the mounting base and the threaded sleeve, the filter screen barrel can be installed and fixed inside the threaded sleeve, thus facilitating installation and disassembly and simplifying operation. Simultaneously, the protective pad and maintenance door restrict the first and second rotating wheels after installation and fixation, ensuring stability during use and preventing detachment.

The utility model discloses a disinfection and sterilization device for pet food production, which comprises a disinfection module, a feeding module and a conveying screw, the feeding module comprises a feeding seat and a charging basket connected with the feeding seat, the disinfection module comprises a light-transmitting inner cylinder connected with the feeding seat, an outer cylinder and a plurality of UV lamp groups, and the UV lamp groups are connected with the feeding seat. The light-transmitting inner cylinder is arranged in the outer cylinder, the conveying screw rod is arranged in the light-transmitting inner cylinder, a plurality of mounting openings are formed in the outer cylinder along the circumference of the outer cylinder in an array mode, the UV lamp sets are movably inserted into the mounting openings, and locking modules used for being connected with the UV lamp sets are arranged on the front side and the rear side of the outer cylinder. By means of the design that the installation openings are formed in the circumference of the outer cylinder in an array mode and the UV lamp sets are movably inserted into the installation openings, the defect that a traditional UV lamp tube is fixedly installed and difficult to disassemble is thoroughly overcome. Operators can conveniently maintain and replace the UV lamp set without a complex disassembly process, so that the maintenance difficulty and the time cost are greatly reduced.

This utility model discloses a blade sharpening device, including a sharpening box with a top cover rotatably fitted to its top. A support platform is installed inside the sharpening box, and transparent windows are provided on both sides of the sharpening box. An annular groove is formed on the top of the support platform, and a movable block is slidably fitted with the annular groove. A sharpening machine is mounted on the top of the movable block. A moving component is positioned between the annular groove and the movable block. A slot corresponding to the annular groove is formed on the top of the top cover, and multiple fixing frames corresponding to the slot are provided on the top of the top cover. Clamping components are installed within the fixing frames. This utility model, through the designed moving component, enables the moving block to move along the annular groove, allowing the moving block to drive the sharpening machine to intermittently sharpen both sides of the blade edge. This allows for safe replacement of the blade without stopping the sharpening machine, effectively improving work efficiency.
