Technical Field
[0001] This utility model relates to the field of razor technology, specifically to a razor protection device. Background Technology
[0002] Manual razors are tools that use physical principles to shave beards or other unwanted body hair. They are self-service tools made of materials such as aluminum, stainless steel, copper, plastic, and rubber. The razor head is made of a combination of blades and plastic / rubber. Modern razors are often exposed to the air, making them prone to damage and lacking protective devices.
[0003] A search revealed that patent application CN216464756U discloses a manual razor that can store shaving cream, including a base, a handle, and a razor head. The base has a handle, which includes a liquid storage chamber, a liquid guide tube, and a pressing device. The liquid guide tube is located inside the handle, and the liquid storage chamber is located at the lower part of the liquid guide tube. The pressing device is located in the middle of the handle. The razor head includes a first blade, a second blade, a third blade, a protective fin, a pusher block, and a liquid dispensing strip. The liquid dispensing strip is located at the lower part of the razor head and one end of the liquid guide tube. This design makes it easy to carry, allowing users to use it anytime, anywhere without other limitations, saving time and effort.
[0004] However, due to the design of the razor head, it is exposed to the outside air. When the razor is dropped, the razor head is easily damaged. The razor head is also prone to dust and rust due to prolonged exposure to the outside air, resulting in poor protection and a short service life. In addition, it is inconvenient to clean the beard off the razor after use.
[0005] Therefore, we propose a razor protection device. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a razor protection device that solves the problems of poor protection and inconvenient cleaning of existing devices.
[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a razor protection device, including a protective shell, wherein a hand-held part is fixedly installed on the bottom surface of the protective shell;
[0008] The protective shell is equipped with a shaver head of the same specifications. The bottom surface of the shaver head is equipped with a support rod. The bottom end of the support rod is fixedly installed with a piston plate that is slidably connected to the inner wall of the protective shell. The bottom surface of the piston plate is fixedly installed with a connecting rod. The bottom end of the connecting rod is fixedly installed with a threaded rod that passes through the bottom surface of the hand grip. The top surface of the protective shell is equipped with a sealing cap of the same specifications through threads.
[0009] The piston plate is fixedly mounted with a matching limit frame on its top surface. The outer wall of the top of the support rod is provided with an installation thread. The bottom surface of the shaver head is provided with a matching threaded hole. The support rod and the shaver head are made of stainless steel.
[0010] Preferably, a base plate of the same specifications is fixedly installed at the bottom end of the threaded rod, which makes it easy to place the device stably on the table and also makes it easy to rotate the threaded rod.
[0011] Preferably, the razor head is equipped with blades of the same size on both the left and right sides, which ensures that the razor head can be used for shaving from both sides, thus improving its practicality.
[0012] Preferably, the outer wall of the handheld part is fitted with a rubber layer of appropriate specifications, and the rubber layer is provided with uniformly distributed anti-slip texture, which can improve the stability of the handheld part and prevent it from slipping and falling to the ground and causing damage.
[0013] Preferably, a matching sealing gasket is fitted on the inner wall of the bottom surface of the sealing cover, which can improve the sealing performance of the sealing cover and prevent external water from entering the protective shell.
[0014] Preferably, a limiting washer located on the bottom surface of the mounting thread is fixedly installed on the outer wall of the support rod. The limiting washer is made of rubber material, which can improve the stability of the shaver head installation.
[0015] 1. This shaver protection device, through the arrangement of a threaded rod and a piston plate, allows the shaver head to be stored and protected after use. When the shaver is used, rotating the threaded rod causes the piston plate to move downwards. The piston plate and support rod then move the shaver head into the protective housing. Finally, the sealing cover is put on, which can store and protect the shaver head, providing good protection and extending its service life.
[0016] 2. At the same time, the setting of the limiting frame and threaded hole allows the beard to fall into the limiting frame during shaving. The threaded hole and mounting thread make it easy to remove the shaver head, which facilitates cleaning of the shaver head and the limiting frame, improving the convenience and cleanliness of beard cleaning.
