DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] The present application provides a kind of print head dry protection seat, as shown in figure Figures 1-6 The print head dry protection seat, including protective shell 1, the outer wall of protective shell 1 is fixedly connected with fixed seat 2, fixed seat 2 is fixedly connected with the hanging ring of being convenient for carrying in the inside, protective shell 1 is provided with protection assembly in the inside;

[0030] Protection assembly includes the notch 3 being opened in the end of protective shell 1, the inner side wall of notch 3 is slidably connected with clamping seat 4, the inner side wall of clamping seat 4 is fixedly connected with multiple friction strips 5, the lower bottom of protective shell 1 is provided with air extraction groove 6, the end of air extraction groove 6 is fixedly connected with vacuum seat 7, the inner wall of vacuum seat 7 is slidably connected with piston 8, the end of piston 8 is fixedly connected with handle.

[0031] The outer wall of protective shell 1 is detachably connected with heating block 17, and the inside of protective shell 1 is inserted with print head 18.

[0032] The outer wall of protective shell 1 is slidably connected with blocking strip 12, the sidewall of blocking strip 12 is provided with circular groove 13, the end of circular groove 13 is fixedly connected with spring 14, and the end of spring 14 is fixedly connected with clamping ball 15.

[0033] The inner wall of the protective shell 1 is provided with a clamping groove 16, and the inner side wall of the clamping groove 16 is symmetrically provided with a clamping groove matched with the clamping ball 15.

[0034] Specifically, by arranging the protective shell 1, the printhead 18 can be conveniently carried or stored. When printing is not performed for a long time, the printhead 18 is inside the printer and is more susceptible to dust in the air, which can cause the outer wall to be dirty. In addition, as the temperature and humidity change, the printhead 18 is more susceptible to drying, which can affect the printing quality and greatly reduce the service life of the printhead 18. By inserting the unused printhead 18 into the clamping seat 4 inside the protective shell 1, the friction between the printhead 18 and the multiple friction strips 5 on the inner wall of the clamping seat 4 is increased, so that the printhead 18 is not loosened due to the shaking of the protective shell 1. When the printhead 18 is clamped, the blocking strip 12 is pushed to slide on the outer wall of the protective shell 1 until the clamping ball 15 on the side wall of the blocking strip 12 is clamped in the clamping groove in the clamping groove 16 on the inner wall of the protective shell 1. The protective shell 1 is sealed at the end to prevent dust and moisture in the external air from entering the inside of the protective shell 1 and affecting the precision components in the printhead 18. Since the end of the clamping ball 15 is provided with a spring 14, the clamping ball 15 is continuously abutted in the clamping groove by the material properties of the spring 14, so that the sealing condition inside the protective shell 1 is not affected when the protective shell 1 shakes. By manually pulling the handle to drive the piston 8 to move in the vacuum seat 7, the air inside the protective shell 1 is extracted to make the inside of the protective shell 1 in a vacuum state. The printhead 18 is stored in a vacuum state to avoid the risk of oxidation and corrosion of various metal materials in the printhead 18 exposed to the air, thereby reducing the service life of the printhead 18. In addition, the vacuum environment has good stability, which can avoid temperature changes of the printhead 18 during storage, thereby avoiding the drying of the printhead 18. By arranging the heating block 17 on the outer wall of the protective shell 1, the temperature of the protective shell 1 can be adjusted according to the external environment temperature, thereby avoiding the influence of low external temperature on the storage quality of the printhead 18. By arranging the fixing seat 2 and the hanging ring on the outer wall of the protective shell 1, the protective shell 1 can be conveniently carried, thereby improving the portability of the printhead 18.

[0035] The inner side wall of the air extraction groove 6 is rotationally connected with a rotating shaft 9, and the outer wall of the rotating shaft 9 is rotationally connected with a check valve 10 for preventing air backflow.

[0036] The side wall of the vacuum seat 7 is fixedly connected with an air exhaust seat 11, and the inner wall of the air exhaust seat 11 is clamped with an air plug.

[0037] Specific, by setting check valve 10 in the air slot 6 inside, then can be in the piston 8 movement drive protection shell 1 in the air to carry on the separation, through one-way movement check valve 10 can avoid air backflow, influence protection shell 1 in the vacuum state, when need to take out the print head 18, take off the air plug on the exhaust seat 11, so that air can enter the protection shell 1 inside, release its internal vacuum state, and then pull the baffle 12, so that the baffle 12 side wall of the ball 15 and card slot separation, open the end of the protection shell 1, and then take out the print head 18, need to explain, check valve 10 has been prior art, therefore, do not make too much superfluous, the component structure is simple, practical, avoid the external environment influence print head 18 situation, greatly reduce the print head 18 appear dry or be electrostatic damage components risk, improve its service life.

[0038] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art within the technical range disclosed by the present application, according to the technical scheme and the utility model concept of the present application, equivalent replacement or change, should be covered in the protection scope of the present application.
