Description

Technical Field

[0001] The utility model relates to the technical field of printer-related equipment, in particular to a toner cartridge powder chamber cover structure. Background Art

[0002] A printer is one of the output devices of a computer, used to print the processing results of the computer on relevant media. There are many types of printers. According to the printing character structure, they are divided into full-shape character printers and dot-matrix character printers. According to the way a line of characters is formed on the paper, they are divided into serial printers and line printers. A toner cartridge is an important part of a printer. The toner cartridge covers the toner on the surface of the paper, and then through a series of steps, the toner is fixed on the surface of the paper to form the required pattern on the paper surface.

[0003] The working principle of the toner cartridge is as follows: after receiving the data to be printed, the toner in the ink cartridge is attracted by the magnetic roller and then typeset onto the photosensitive drum, and then the photosensitive drum prints the toner onto the paper. Since the toner in the toner cartridge is the key to imaging during the printing process, the printing quality is largely determined by the toner cartridge. In order to increase the service life of the toner cartridge, the existing toner cartridges can all be refilled with toner.

[0004] The existing toner cartridge powder chamber refilling structure generally consists of a cylindrical plug cooperating with the refilling port, so there are the following deficiencies:

[0005] 1. The surface of the plug is smooth, and it is easy to have a fitting gap when cooperating with the refilling port. Those tiny gaps cause the toner in the powder chamber to flow out, polluting the printing environment;

[0006] 2. When the cover needs to be removed, since the inside of the plug is adhered with toner, directly pulling it out easily causes the toner in the powder chamber to accidentally leak, resulting in environmental pollution and waste of resources. Content of the Utility Model

[0007] I. Technical Problems to be Solved

[0008] The technical problem to be solved by the utility model is that it is easy to leak and carry out toner, resulting in environmental pollution and waste of resources.

[0009] II. Technical Solution

[0010] To solve the above technical problems, the technical solution provided by the utility model is: a toner cartridge powder chamber cover structure, including a cartridge main body, wherein a feeding port is arranged on the side wall of the cartridge main body, and a chamber cover is inserted into the feeding port.

[0011] The chamber cover is composed of a plurality of connected cylinders, and the cross-section is an H-shaped structure. The diameter of the cylinder in the middle of the chamber cover is the same as the diameter of the feeding port, and the length is the same as the thickness of the cartridge main body at the feeding port.

[0012] The described cartridge cover is made of elastic rubber material. One end of the cartridge cover located inside the ink cartridge body is a convex curved surface structure, and there is a cavity inside. The other end of the cartridge cover is provided with a through hole communicating with the cavity, and a push rod is inserted into the through hole.

[0013] As an improvement, one end of the cartridge cover far from the feed port is connected with a cylinder, the other end of the cylinder is connected with a snowflake-shaped pull plate, and there is a through hole two on the pull plate.

[0014] As an improvement, the diameter of the through hole two is equal to the inner diameter of the cylinder and equal to the diameter of the through hole.

[0015] As an improvement, the length of the end of the pull plate from the through hole two is greater than the radius of the feed port.

[0016] As an improvement, one end of the push rod far from the cartridge cover is provided with a disc, one end of the disc facing the cartridge cover is connected with a spring, and the other end of the spring is in contact with the pull plate.

[0017] As an improvement, one end of the push rod facing the cartridge cover is a convex curved surface structure.

[0018] As an improvement, the feed port includes a hole one communicating with the ink cartridge body and a hole two communicating with the outside. The hole one communicates with the hole two, and the diameter of the hole one is smaller than the diameter of the hole two. The cylinder in the middle of the cartridge cover is matched with the hole one, and the cylinder far from the ink cartridge body is located in the hole two.

[0019] III. Beneficial Effects

[0020] The advantages of the present utility model compared with the prior art are as follows:

[0021] 1. Since the cartridge cover is an H-shaped structure and is inserted into the feed port, it can well seal the feed port and prevent the grinding powder from leaking from the feed port.

[0022] 2. Since the cartridge cover is made of rubber material, and the diameter of the part located inside the feed port is larger than the feed port, and one end of the cartridge cover located inside the ink cartridge body is a convex curved surface structure with a cavity inside, when pulling out, the part of the cartridge cover located inside the ink cartridge body will sink towards the center of the cartridge cover, and will rebound after loosening, bouncing off the toner on the cartridge cover, and then pulling out the cartridge cover can avoid the toner following out, reducing environmental pollution and waste of resources.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1

[0031] As shown in the attached Figure 1 、 attached Figure 2 and attached Figure 3 shown, a toner cartridge powder chamber cover structure includes an ink cartridge main body 1, a feed port 2 is provided on the side wall of the ink cartridge main body 1, a cover 3 is inserted into the feed port 2, the cover 3 is composed of a plurality of connected cylinders, and the cross section is an H-shaped structure. The diameter of the cylinder in the middle of the cover 3 is the same as the diameter of the feed port 2, and the length is the same as the thickness of the ink cartridge main body 1 at the feed port 2; the cover 3 is made of elastic rubber material, one end of the cover 3 located inside the ink cartridge main body 1 is a convex curved surface structure, and a cavity 4 is provided inside, and a through hole 5 communicating with the cavity 4 is provided at the other end of the cover 3, and a thumb rod 6 is inserted into the through hole 5.

[0032] With the above structure, since the cross-section of the storage cover 3 is an H-shaped structure and is inserted into the feed inlet 2, the diameter of the cylinder in the middle of the storage cover 3 is the same as that of the feed inlet 2, and the length is the same as the thickness of the ink cartridge body 1 at the feed inlet 2. Therefore, it can seal the feed inlet well and prevent the milled powder from leaking from the feed inlet. Since the storage cover 3 is made of rubber, the diameter of the cylinder located in the feed inlet 2 is larger than that of the feed inlet 2, and the end located in the ink cartridge body 1 is a convex curved surface structure with a cavity inside. Therefore, when pulling out, the part of the storage cover 3 located in the ink cartridge body 1 will sink towards the center of the storage cover 3 and rebound after loosening. First, pull out a part back and forth to bounce off the toner on the storage cover 3, and then pull out the storage cover 3, which can prevent the toner from following out and reduce environmental pollution and waste of resources. If the rebound fails due to excessive pulling out, the storage cover 3 is provided with a through hole 5 communicating with the cavity 4, and a ejector rod 6 is inserted into the through hole 5, which can be inserted and lifted when the end of the storage cover 3 located in the ink cartridge body 1 does not return to the convex curved surface structure.

[0033] Embodiment Two

[0034] On the basis of Embodiment One, please refer to the attached Figure 4 and the attached Figure 5

[0035] One end of the storage cover 3 away from the feed inlet 2 is connected to a cylinder 7, and the other end of the cylinder 7 is connected to a snowflake-shaped pull plate 8. A through hole two 9 is provided on the pull plate 8; the diameter of the through hole two 9 is equal to the inner diameter of the cylinder 7 and equal to the diameter of the through hole 5; the length of the end of the pull plate 8 from the through hole two 9 is greater than the radius of the feed inlet 2.

[0036] With the above structure, the structure of the pull plate 8 is more convenient to hold, facilitating the installation and disassembly of the storage cover 3.

[0037] One end of the ejector rod 6 away from the storage cover 3 is provided with a disc 10. One end of the disc 10 facing the storage cover 3 is connected to a spring 11, and the other end of the spring 11 is in contact with the pull plate 8; one end of the ejector rod 6 facing the storage cover 3 is a convex curved surface structure.

[0038] With the above structure, the inserted end of the ejector rod 6 is rounded to avoid damaging the storage cover 3, and the spring 11 can rebound after the ejector rod 6 pushes open the cavity, making it convenient for the ejector rod 6 to retract.

[0039] The feed inlet 2 includes a hole one communicating with the ink cartridge body 1 and a hole two communicating with the outside. The hole one communicates with the hole two, and the diameter of the hole one is smaller than that of the hole two. The cylinder in the middle of the storage cover 3 is matched with the hole one, and the cylinder away from the ink cartridge body 1 is located in the hole two.

[0041] The specific usage method is as follows: Holding the pull plate 8 can insert the bin cover 3 into the feed inlet 2. The cross-section of the bin cover 3 is an H-shaped structure. The diameter of the cylinder in the middle of the bin cover 3 is the same as that of the feed inlet 2, and the length is the same as the thickness of the ink cartridge body 1 at the feed inlet 2. Therefore, it can seal the feed inlet well and prevent the milled powder from leaking from the feed inlet.

[0042] When it is necessary to pull out the bin cover 3, since the bin cover 3 is made of rubber, the diameter of the cylinder located in the feed inlet 2 is larger than that of the feed inlet 2, and one end located in the ink cartridge body 1 is a convex curved surface structure with a cavity inside. Therefore, when pulling out, the part of the bin cover 3 located in the ink cartridge body 1 will sink towards the center of the bin cover 3 and rebound after being released. First, pull out part of it back and forth to bounce off the toner on the bin cover 3, and then pull out the bin cover 3, which can prevent the toner from following out and reduce environmental pollution and waste of resources; if the rebound fails due to excessive pulling out, the bin cover 3 is provided with a through hole 5 communicating with the cavity 4, and a ejector rod 6 is inserted in the through hole 5, which can be inserted and lifted when one end of the bin cover 3 located in the ink cartridge body 1 does not return to the convex curved surface structure. The spring 11 can rebound after the ejector rod 6 opens the cavity, making it convenient for the ejector rod 6 to retract.
