[0056] The following will provide a detailed description of the printing device provided by the embodiments of the present utility model in conjunction with specific embodiments.

[0057] Embodiment 1

[0058] Refer to Figure 1 As shown, the embodiments of the present utility model provide a printing device. The left - right direction of the printing device is the X - axis direction, the front - back direction of the printing device is the Y - axis direction, and the up - down direction of the printing device is the Z - axis direction. The X - axis, Y - axis, and Z - axis are perpendicular to each other. The Z - axis direction represents the vertical direction.

[0059] The printing device includes a body 10. One end of the body 10 in the +X - axis direction is the left end 101, and one end of the body 10 in the - X - axis direction is the right end 102. One end of the body 10 in the +Y - axis direction is the rear end 103, and one end of the body 10 in the - Y - axis direction is the front end 104. One end of the body 10 in the +Z - axis direction is the top end 105, and one end of the body 10 in the - Z - axis direction is the bottom end 106.

[0060] Refer to Figure 1 and Figure 2 As shown, the printing device includes a carriage 20. The carriage 20 is arranged inside the body 10. The carriage 20 has a print head and a bracket. The print head can eject liquid onto the developing medium to form the text or pattern to be printed on the medium.

[0061] The bracket has a receiving space 201, and the receiving space 201 can accommodate the ink cartridge 100. The ink cartridge 100 stores the liquid required for printing. In some examples, the receiving space 201 can accommodate 4 ink cartridges 100.

[0062] The carriage 20 can make a reciprocating motion along the slide rod driven by a motor. The reciprocating motion of the carriage 20 is along the X - axis direction. It can be understood that the slide rod extends along the X - axis direction.

[0063] In the left - right direction of the printing device, the carriage 20 has a moving area. The area between the leftmost end and the rightmost end where the carriage 20 moves in the X - axis direction is the moving area of the carriage 20.

[0064] The printing device includes a machine cover 30. The machine cover 30 is rotatably installed on the top end 105 of the body 10. Opening the machine cover 30 can open the top end 105 of the body 10. Closing the machine cover 30 can close the top end 105 of the body 10.

[0065] The printing device includes a board member 40. The board member 40 is arranged inside the body 10 to protect the structure inside the printing device and prevent it from being exposed. The material of the board member 40 can be plastic.

[0066] In the front-rear direction of the printing device, the plate member 40 is located on the side of the carriage 20 closer to the rear end 103 of the machine body 10. That is, in the front-rear direction of the printing device, the plate member 40 is located on the rear side of the carriage 20.

[0067] In the front-rear direction of the printing device, the plate member 40 is located on the side of the carriage 20 closer to the top end 105 of the machine body 10. That is, in the front-rear direction of the printing device, the plate member 40 is located on the upper side of the carriage 20.

[0068] The printing device includes a metal member 50. Only a part of the metal member 50 is shown in Figure 2 the figure.

[0069] The material of the metal member 50 is metal. Part of the metal member 50 is disposed between the carriage 20 and the plate member 40. The metal member 50 can be connected to other components of the machine body 10. Or, the metal member 50 can also be in a charged state.

[0070] In the front-rear direction of the printing device, the metal member 50 is closer to the rear end of the machine body 10 relative to the carriage 20. That is, in the front-rear direction of the printing device, the metal member 50 is located on the rear side of the carriage 20.

[0071] In the up-down direction of the printing device, part of the metal member 50 is closer to the top end 105 of the machine body 10 relative to the carriage 20, and the metal member 50 is farther from the top end 105 of the machine body 10 relative to the plate member 40. That is, in the up-down direction of the printing device, part of the metal member 50 is located on the upper side of the carriage 20, and the metal member 50 is located on the lower side of the plate member 40.

[0072] When the machine cover 30 is opened and observed along the -Z axis direction, the metal member 50 is blocked by the plate member 40, making the interior of the printing device aesthetically pleasing.

[0073] The printing device includes a non-conductive part 60. In the front-rear direction of the printing device, the non-conductive part 60 is disposed at the front end of the metal member 50. One end of the metal member 50 in the -Y axis direction is the front end of the metal member 50.

[0074] In some examples, the non-conductive part 60 is an occlusion member. In the front-rear direction of the printing device, the front end of the occlusion member is farther from the rear end 103 of the machine body 10 relative to the front end of the metal member 50.

[0075] One end of the occlusion member in the -Y axis direction is the front end of the occlusion member.

[0076] The shielding member is disposed on the side of the metal member 50 facing the carriage 20, and the shielding member is configured to shield at least a part of the metal member 50 to reduce the probability that a user or the chip of the ink cartridge touches the metal member 50. With such a setting, when the ink cartridge 100 is disassembled or installed, the shielding member can reduce the probability that the user touches the metal member 50, making it difficult for the user to touch the metal member 50 and avoiding damage to the functions of the machine body, thereby protecting the printing device. Alternatively, when the ink cartridge 100 is disassembled or installed, the shielding member can reduce the probability that the chip of the ink cartridge touches the metal member 50, making it difficult for the chip of the ink cartridge 100 to touch the metal member 50 and avoiding short circuit of the chip, thereby protecting the ink cartridge 100.

[0077] It should be noted that the shielding member is non-conductive and can be in contact with the metal member 50 or not in contact with the metal member 50.

[0078] In a possible implementation, as shown in Figure 2 shown, the shielding member is connected to the side of the board member 40 facing the carriage 20. With such a setting, the shielding member can be fixed on the board member 40 to shield at least a part of the metal member 50 to reduce the probability that a user or the chip of the ink cartridge touches the metal member 50.

[0079] Among them, the shielding member and the board member 40 can be connected by means such as bonding, welding or clamping. Alternatively, the shielding member can also be integrally formed with the board member 40.

[0080] In the front-rear direction of the printing device, a shielding member is disposed between the carriage 20 and the metal member 50 at any position in its moving area. It can be understood that the shielding member shields the part of the metal member 50 corresponding to the moving area of the carriage 20. With such a setting, when the carriage 20 is at any position in its moving area, it can make it difficult for a user or the chip of the ink cartridge to touch the metal member 50.

[0081] In the up-down direction of the printing device, the shielding member shields the metal member 50. As shown in Figure 2 and Figure 3 shown, in the up-down direction of the printing device, the projection of the shielding member in the front-rear direction of the printing device covers the projection of the metal member 50 in the front-rear direction of the printing device.

[0082] The position of the shielding member on the board member 40 is not specifically limited as long as it makes it difficult for a user or the chip of the ink cartridge to touch the metal member 50.

[0083] Further, as shown in Figure 3 shown, in the left-right direction of the printing device, the size of the shielding member is greater than or equal to the size of the moving area. With such a setting, when the carriage 20 is at any position in its moving area, the shielding member can shield the metal member 50.

[0084] In the left-right direction of the printing apparatus, the dimension of the shielding member is L1.

[0085] In the left-right direction of the printing apparatus, the size of the moving area of ​​the carriage 20 is the size between the leftmost end and the rightmost end of the movement of the carriage 20 in the left-right direction of the printing apparatus.

[0086] See also Figure 2 and Figure 3 As shown, in the up-down direction of the printing device, the size of the shielding member is greater than or equal to the size of the metal member 50. In this way, the shielding member can shield the metal member 50 in the up-down direction of the printing device.

[0087] In the up-down direction of the printing apparatus, the dimension of the shielding member is L2.

[0088] The dimension of the metal member 50 in the vertical direction of the printing apparatus is L3.

[0089] In a possible implementation manner, the shielding member is located on a side of the plate component 40 that is away from the top end 105 of the body 10 , and the shielding member extends in a direction away from the top end 105 .

[0090] The shielding member may be a shielding plate, which is intersected and connected with the plate component 40. In some examples, the shielding plate is vertically connected with the plate component 40. The shielding plate extends along the up-down direction of the printing device.

[0091] The metal member 50 may be a metal plate. The shielding plate may be parallel to the metal plate. In other embodiments, the shielding plate may not be parallel to the metal plate.

[0092] Modification 1 of Embodiment 1

[0093] The printing device in the first variant of the first embodiment is different from the printing device in the first embodiment in that the shielding member is connected to the machine body, but is not connected to the plate member, that is, the shielding member is mounted on the machine body.

[0094] The shielding member and the body can be connected by bonding, welding or clamping, etc. Alternatively, the shielding member and the body can also be formed in one piece.

[0095] It should be noted that, in other embodiments, the shielding member may also be connected to the machine body and the plate component, that is, the shielding member is installed on the machine body and the plate component.

[0096] Regarding the remaining structures, Modification 1 of Embodiment 1 is the same as Embodiment 1.

[0097] Modification 2 of Embodiment 1

[0098] The printing device in the second variant of the first embodiment is different from the printing device in the first embodiment in that:Figure 4 and Figure 5 As shown in Figure 5 , the shielding member is connected to the carriage 20 and not connected to the plate member 40. That is to say, the shielding member is mounted on the carriage 20.

[0099] Among them, the shielding member and the carriage 20 can be connected by means such as bonding, welding or clamping. Or, the shielding member can also be integrally formed with the bracket of the carriage 20.

[0100] The shielding member is connected to the side of the carriage 20 facing the plate member 40. With such a setting, the shielding member can be fixed on the carriage 20 to shield at least part of the metal member 50, so as to reduce the probability that the user or the chip of the ink cartridge touches the metal member 50.

[0101] The position of the shielding member on the carriage 20 is not specifically limited, as long as it makes it difficult for the user or the chip of the ink cartridge to touch the metal member 50.

[0102] In a possible implementation manner, the shielding member is located on the side of the carriage 20 close to the top end 105 of the machine body 10, and the shielding member extends in the direction close to the top end 105 of the machine body 10.

[0103] The shielding member can be a shielding plate. The shielding plate is intersectingly connected to the carriage 20. In some examples, the shielding plate is perpendicularly connected to the carriage 20. The shielding plate extends along the up-down direction of the printing device.

[0104] In the left-right direction of the printing device, the size of the shielding member is greater than or equal to the size of the accommodation space 201 of the carriage 20. With such a setting, when the carriage 20 is at any position in its moving area, the shielding member can shield the metal member 50.

[0105] In the left-right direction of the printing device, the size of the shielding member is L5. In the left-right direction of the printing device, the size of the accommodation space 201 of the carriage 20 is L4.

[0106] In the up-down direction of the printing device, the shielding member shields part of the metal member 50. In the up-down direction of the printing device, the projection of the shielding member in the front-back direction of the printing device covers the projection of part of the metal member 50 in the front-back direction of the printing device. It can be understood that when observing the shielding member along the +Y axis direction, part of the metal member 50 can be seen.

[0107] For the structures of the remaining parts, Variant Example 2 of Embodiment 1 is the same as Embodiment 1.

[0108] Embodiment 2

[0109] See Figure 6 and Figure 7As shown, the difference between the printing device in Embodiment 2 and that in Embodiment 1 is that: the non-conductive part 60 is arranged on the metal part 50, and the non-conductive part 60 includes an avoidance structure. The avoidance structure is an elliptical hole structure on the metal part 50. When disassembling or installing the ink cartridge, the avoidance structure can avoid the user, which can reduce the probability of the user touching the metal part 50, making it difficult for the user to touch the metal part 50. When disassembling or installing the ink cartridge, the avoidance structure can avoid the chip of the ink cartridge 100, which can reduce the probability of the chip of the ink cartridge 100 touching the metal part 50, making it difficult for the chip of the ink cartridge 100 to touch the metal part 50.

[0110] When disassembling or installing the ink cartridge 100, in the front-back direction of the printing device, the non-conductive part 60 can be arranged at the position corresponding to the ink cartridge 100 on the metal part 50.

[0111] In the left-right direction of the printing device, when the carriage 20 moves to the leftmost end, the non-conductive part 60 can be arranged at the position corresponding to the ink cartridge 100 on the metal part 50.

[0112] In the left-right direction of the printing device, when the carriage 20 moves to the rightmost end, the non-conductive part 60 can be arranged at the position corresponding to the ink cartridge 100 on the metal part 50.

[0113] The metal part 50 includes a first plate 51 and a second plate 52. Among them, the part of the metal part 50 located above the carriage 20 includes the first plate 51 and the second plate 52.

[0114] The first plate 51 and the second plate 52 are intersectingly connected. In some examples, the first plate 51 and the second plate 52 are perpendicular to each other.

[0115] In the up-down direction of the printing device, the first plate 51 is higher than the second plate 52, that is to say, the first plate 51 is located above the second plate 52. In the front-back direction of the printing device, the second plate 52 faces the front end 104 of the machine body 10.

[0116] The non-conductive part 60 is located on the second plate 52 of the metal part 50.

[0117] In the front-back direction of the printing device, the non-conductive part 60 penetrates through the second plate 52 of the metal part 50.

[0118] In the left-right direction of the printing device, a plurality of non-conductive parts 60 are arranged on the second plate 52, and the plurality of non-conductive parts 60 are arranged at intervals.

[0119] Further, in the left-right direction of the printing device, the width of the non-conductive part 60 is greater than the width of the chip of the ink cartridge 100. When disassembling or installing the ink cartridge, it is difficult for the chip of the ink cartridge 100 to touch the metal part 50.

[0120] For the structure of the remaining part, it is the same as that in Embodiment 2 and Embodiment 1.

[0121] Variant Example 1 of Embodiment 2

[0122] See Figure 8 and Figure 9 As shown, the difference between the printing device in Variant Example 1 of Embodiment 2 and the printing device in Embodiment 2 is that the avoidance structure is a square hole structure on the metal part 50.

[0123] In the up - down direction of the printing device, the avoidance structure penetrates one end of the second plate 52 facing the bottom end 106 of the machine body 10.

[0124] For the structure of the remaining part, Variant Example 1 of Embodiment 2 is the same as Embodiment 2.

[0125] Variant Example 2 of Embodiment 2

[0126] See Figure 10 and Figure 11 As shown, the difference between the printing device in Variant Example 2 of Embodiment 2 and the printing device in Variant Example 1 of Embodiment 2 is that the avoidance structure is an L - shaped hole structure on the metal part 50.

[0127] The avoidance structure is not only located on the second plate 52, but also on the first plate 51.

[0128] In the up - down direction of the printing device, the avoidance structure penetrates the first plate 51 of the metal part 50.

[0129] For the structure of the remaining part, Variant Example 2 of Embodiment 2 is the same as Variant Example 1 of Embodiment 2.

[0130] Variant Example 3 of Embodiment 2

[0131] See Figure 12 and Figure 13 As shown, the difference between the printing device in Variant Example 3 of Embodiment 2 and the printing device in Variant Example 1 of Embodiment 2 is that in the up - down direction of the printing device, the avoidance structure does not penetrate one end of the second plate 52 facing the bottom end 106 of the machine body 10.

[0132] For the structure of the remaining part, Variant Example 2 of Embodiment 2 is the same as Variant Example 2 of Embodiment 2.

[0133] Variant Example 4 of Embodiment 2

[0134] See Figure 14 and Figure 15 As shown, the difference between the printing device in Variant Example 4 of Embodiment 2 and the printing device in Variant Example 1 of Embodiment 2 is that the avoidance structure is a groove structure on the metal part 50.

[0135] In the front-rear direction of the printing device, the second plate 52 can be stamped to form a groove structure.

[0136] For the structures of the remaining parts, Modification Example 3 of Embodiment 2 is the same as Embodiment 2.

[0137] Embodiment 3

[0138] The difference between the printing device in Embodiment 3 and the printing device in Embodiment 2 is that: the non-conductive part further includes a non-conductive member, the non-conductive member is embedded in the metal member, the avoidance structure is provided on the metal member, and the non-conductive member is located within the avoidance structure, that is, on the inner wall of the elliptical hole structure. With such an arrangement, the user can touch the inner wall of the elliptical hole structure, which can reduce the probability of the user touching the metal member, making it difficult for the user to touch the metal member. The chip of the ink cartridge can touch the inner wall of the elliptical hole structure, which can reduce the probability of the chip of the ink cartridge touching the metal member, making it difficult for the chip of the ink cartridge to touch the metal member.

[0139] The non-conductive member is a non-conductive component.

[0140] For the structures of the remaining parts, Embodiment 3 is the same as Embodiment 2.

[0141] In other possible ways, the solutions of Embodiment 1, Embodiment 2, and Embodiment 3 can be set on the printing device simultaneously.

[0142] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
