[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] Please see Figure 1 and Figure 2 This application provides a printer 100, which includes a printer body 10. The top surface of the printer body 10 has a receiving cavity 101 and a first hand position groove 102 and a second hand position groove 103. The receiving cavity 101 is used to place a consumable box 20. The first hand position groove 102 and the second hand position groove 103 are located on opposite sides of the receiving cavity 101, and both the first hand position groove 102 and the second hand position groove 103 are in communication with the receiving cavity 101. The printer body 10 defines all the connecting lines that define the wall of the first hand position groove 102 and the wall of the second hand position groove 103. The projection on the first side of the printer body 10 forms a force application area. The consumable box 20 disposed in the receiving cavity 101 has a center point, and the projection of the center point on the first side is located within the force application area.

[0036] It should be noted that the consumable cartridge 20 can be an ink cartridge, ribbon cartridge, or toner cartridge, etc. The printer 100 can use the consumables (such as ink, ribbon, toner, etc.) in the consumable cartridge 20 to complete the printing work. The printer body 10 has a cuboid-like structure. The side of the printer body 10 facing the cover is the top surface of the printer body 10. The top surface of the printer body 10 has a receiving cavity 101 and a first hand position groove 102 and a second hand position groove 103. The inner contour shape of the receiving cavity 101 is similar to that of the consumable cartridge 20. The outer contour shape is adapted to each other, and they can all be similar to cuboid structures, so that the consumable box 20 can be assembled in the receiving cavity 101. The first hand position groove 102 and the second hand position groove 103 are located on opposite sides of the receiving cavity 101, and the first hand position groove 102 and the second hand position groove 103 are both connected to the receiving cavity 101. When it is necessary to replace the consumable box 20, the user can place his / her hand in the first hand position groove 102 and the second hand position groove 103 and take the consumable box 20 out of the receiving cavity 101 with his / her fingers.

[0037] More specifically, both the first hand-held groove 102 and the second hand-held groove 103 are recesses formed by the top surface of the printer body 10 being recessed inward. The first hand-held groove 102 and the second hand-held groove 103 are located on different sides of the receiving cavity 101, and both the first hand-held groove 102 and the second hand-held groove 103 are connected to the receiving cavity 101. All the lines connecting the wall surface of the first hand-held groove 102 and the wall surface of the second hand-held groove 103 defined by the printer body 10 form a force application area on the projection of the first side surface of the printer body 10. The center point of the consumable box 20, which is located in the receiving cavity 101, is located in the force application area on the projection of the first side surface. This allows the user's hand to apply force towards the center point of the consumable box 20 when the user picks up the consumable box 20, making it easier for the user to grip the consumable box 20 and to easily remove the consumable box 20 from the receiving cavity 101.

[0038] In this embodiment, the first hand position groove 102 has a first groove inner surface and a first groove bottom surface, and the second hand position groove 103 has a second groove inner surface and a second groove bottom surface. Any point on the first groove inner surface can form a line with any point on the second groove inner surface or any point on the second groove bottom surface, and any point on the first groove bottom surface can also form a line with any point on the second groove inner surface or any point on the second groove bottom surface. The side of the printer body 10 with the first hand position groove 102 is defined as the first side surface. Thus, the projection of all the lines connecting the first groove inner surface and the first groove bottom surface with the second groove inner surface and the second groove bottom surface on the first side surface can form a force application area. The projection of the center point of the top surface of the consumable box 20 on the first side surface is located within the force application area. When the user picks up the consumable box 20, the fingers located in the first hand position groove 102 and the fingers located in the second hand position groove 103 can apply force to the center point of the consumable box 20, thereby making it convenient for the user to grip the consumable box 20 and to easily remove the consumable box 20 from the receiving cavity 101.

[0039] Please see Figure 3 In some embodiments, the first hand slot 102 has a dimension of a1 along the width direction of the printer body 10, and the second hand slot 103 has a dimension of a2 along the width direction of the printer body 10. a1 and a2 satisfy: 8mm≤a1≤30mm, 8mm≤a2≤30mm.

[0040] It should be noted that, Figure 1 The X-axis direction in the figure represents the width direction of the printer body 10. Figure 1 The Y-axis direction in the figure represents the length direction of the printer body 10. Figure 1 The Z-axis direction in the figure represents the height direction of the printer body 10.

[0041] If dimension a1 is less than 8mm, the size of the first hand position groove 102 will be too small, making it inconvenient for the thumb to be inserted into the first hand position groove 102. Similarly, if dimension a2 is less than 8mm, the size of the second hand position groove 103 will also be too small, making it inconvenient for the index, ring, and middle fingers to be inserted into the second hand position groove 103.

[0042] If a1 is greater than 30mm, the size of the first hand slot 102 will be too large, causing interference between it and other internal components of the printer body 10. This will affect the arrangement of other internal components and increase the size of the printer 100. Similarly, if a2 is greater than 30mm, the same adverse effects will occur. Therefore, when a1 and a2 satisfy 8mm≤a1≤30mm and 8mm≤a2≤30mm, it is convenient to remove the consumable box 20 without affecting the arrangement of other internal components of the printer body 10.

[0043] In this embodiment, since the thumb can be placed in the first hand slot 102, and the index finger, ring finger and middle finger can be placed in the second hand slot 103, and a1 and a2 also satisfy a1 < a2, the space on the top surface of the printer body 10 can be utilized more rationally, making the printer 100 more compact and reducing the size of the printer 100.

[0044] Please see Figure 3 In some embodiments, the first hand slot 102 has a dimension of b1 along the length of the printer body 10, and the second hand slot 103 has a dimension of b2 along the length of the printer body 10. b1 and b2 satisfy: 6mm≤b1≤15mm, 6mm≤b2≤15mm.

[0045] Alternatively, if the size b1 is less than 6mm, the size of the first hand position groove 102 will be too small, making it inconvenient for the thumb to be inserted into the first hand position groove 102. Similarly, if the size b2 is less than 6mm, the size of the second hand position groove 103 will also be too small, making it inconvenient for the index finger, ring finger and middle finger to be inserted into the second hand position groove 103.

[0046] If dimension b1 is greater than 15mm, although the thumb can easily fit into the first handgrip slot 102, the size of the first handgrip slot 102 is too large, which would increase the size of the printer 100. Similarly, if dimension b2 is greater than 15mm, although the index, ring, and middle fingers can easily fit into the second handgrip slot 103, the size of the second handgrip slot 103 is too large, which would also increase the size of the printer 100. Therefore, when b1 and b2 satisfy: 6mm≤b1≤15mm, 6mm≤b2≤15mm, it is convenient to handle the consumable box 20 without increasing the size of the printer 100.

[0047] Please see Figure 4 In some embodiments, the distance between the bottom surface of the first hand position slot 102 and the top surface of the consumable box 20 along the height direction of the printer body 10 is c1, and the distance between the bottom surface of the second hand position slot 103 and the top surface of the consumable box 20 along the height direction of the printer body 10 is c2. c1 and c2 satisfy: 8mm≤c1≤20mm, 8mm≤c2≤20mm.

[0048] Optionally, the height direction of the printer body 10 and the depth direction of the first hand position slot 102 are aligned in the same direction. If the dimension c1 is less than 8mm, the distance between the bottom surface of the first hand position slot 102 and the top surface of the consumable box 20 will be too small. After the thumb is inserted into the first hand position slot 102, the contact area between the thumb and the consumable box 20 will be too small, resulting in insufficient friction between the thumb and the consumable box 20. The thumb will easily slip out of the first hand position slot 102, making it inconvenient to pick up the consumable box 20. If the dimension c1 is greater than 20mm, although the contact area between the thumb and the consumable box 20 is large enough after the thumb is inserted into the first hand position slot 102, allowing the thumb to remove the consumable box 20 from the receiving cavity 101, it will increase the size of the printer body 10.

[0049] Similarly, the height direction of the printer body 10 and the depth direction of the second hand position slot 103 are in the same direction. If the dimension c2 is less than 8mm, the distance between the bottom surface of the second hand position slot 103 and the top surface of the consumable box 20 will be too small. After the index, ring, and middle fingers are inserted into the first hand position slot 102, the contact area between them and the consumable box 20 will be too small, resulting in insufficient friction between the index, ring, and middle fingers and the consumable box 20. The index, ring, and middle fingers will easily slip out of the first hand position slot 102, making it inconvenient to pick up the consumable box 20. If the dimension c1 is greater than 20mm, although the contact area between the index, ring, and middle fingers and the consumable box 20 is large enough to remove the consumable box 20 from the receiving cavity 101, it will cause the printer body 10 to become larger.

[0050] Therefore, when c1 and c2 satisfy: 8mm≤c1≤20mm, 8mm≤c2≤20mm, the consumable box 20 can be easily removed from the receiving cavity 101 without causing the printer body 10 to become larger.

[0051] Please see Figure 1 In some embodiments, the first hand slot 102 and the second hand slot 103 are located on opposite sides of the printer body 10.

[0052] Optionally, the first hand slot 102 and the second hand slot 103 are arranged along the length of the printer body 10, and the first hand slot 102 and the second hand slot 103 are located on opposite sides of the receiving cavity 101. When the user takes the consumable box 20 out of the receiving cavity 101, he / she places his / her thumb in the first hand slot 102 and places at least one of his / her index, ring, and middle fingers in the second hand slot 103. The consumable box 20 can be held by the thumb and at least one of his / her index, ring, and middle fingers, and can be easily taken out of the receiving cavity 101.

[0053] Please see Figure 1and Figure 2 In some embodiments, the printer 100 further includes a printing roller 30, which is mounted on the printer body 10, and the first hand slot 102 is located on the same side of the printer body 10 as the printing roller 30.

[0054] Optionally, the thumb can be placed in the first hand slot 102, and the index, ring, and middle fingers can all be placed in the second hand slot 103. Therefore, a1 and a2 also satisfy a1 < a2. The first hand slot 102 and the printing roller 30 are set on the same side of the printer body 10, so that the first hand slot 102 and the printing roller 30 can be reasonably set on the same side. The first hand slot 102 will not affect the setting of the printing roller 30. If the second hand slot 103 and the printing roller 30 are set on the same side, since the size a2 of the second hand slot 103 is larger than the size a1 of the first hand slot 102, in order to set the second hand slot 103 and the printing roller 30 together, the size of the printer body 10 in the width direction needs to be designed to be larger, which will increase the volume of the printer 100.

[0055] Please see Figure 4 In some embodiments, the printer body 10 defines a gap d between the inner wall of the receiving cavity 101 and the consumable box 20, where d satisfies: 0.3mm≤d≤2mm.

[0056] Optionally, if d is less than 0.3mm, the consumable cartridge 20 will fit too tightly with the printer body 10 after being assembled into the receiving cavity 101, making it inconvenient to replace the consumable cartridge 20 later and also inconvenient to assemble the consumable cartridge 20 into the receiving cavity 101. If d is greater than 2mm, the gap between the consumable cartridge 20 and the inner wall of the receiving cavity 101 will be too large, making the consumable cartridge 20 unstable in the receiving cavity 101 and prone to shaking, affecting the normal printing of the printer 100. Therefore, when d satisfies: 0.3mm≤d≤2mm, it is convenient to pick up and assemble the consumable cartridge 20, and the consumable cartridge 20 is not prone to shaking in the receiving cavity 101.

[0057] Please see Figure 2 , Figure 3 as well as Figure 5 In some embodiments, the printer body 10 defines an inner wall of a receiving cavity 101 on which one of a hook portion 104 and a mating portion 21 is provided, and the outer side of the consumable box 20 is provided with the other of the hook portion 104 and the mating portion 21. The consumable box 20 is disposed in the receiving cavity 101, and the hook portion 104 and the mating portion 21 engage and cooperate.

[0058] In this embodiment, the inner side of the receiving cavity 101 is provided with a plurality of hook portions 104, which are distributed at intervals around the height direction of the printer body 10. The outer side of the consumable box 20 is provided with a plurality of mating portions 21. When the consumable box 20 is assembled into the receiving cavity 101, the plurality of hook portions 104 and the plurality of mating portions 21 are engaged one-to-one, so that the consumable box 20 is stably assembled into the receiving cavity 101. When the consumable box 20 needs to be replaced, the consumable box 20 can be grasped by hand to disengage the mating portions 21 from the hook portions 104, and the consumable box 20 can be easily removed from the receiving cavity 101.

[0059] In other embodiments, the inner side of the receiving cavity 101 may be provided with a mating part 21, and the outer side of the consumable box 20 may be provided with a hook part 104. Alternatively, the inner side of the receiving cavity 101 may be provided with a mating part 21 and a hook part 104, and the outer side of the consumable box 20 may be provided with a hook part 104 and a mating part 21.

[0060] Please see Figure 2 , Figure 3 as well as Figure 5 In some embodiments, at least one hook portion 104 is located on the side of the printer body 10 where the first hand position groove 102 is provided, and / or, at least one hook portion 104 is located on the side of the printer body 10 where the second hand position groove 103 is provided.

[0061] Optionally, the inner side of the receiving cavity 101 is provided with two hook portions 104, and the two hook portions 104 are distributed at intervals along the length direction of the printer body 10. At least one hook portion 104 is correspondingly provided with the first hand position groove 102, or at least one hook portion 104 is correspondingly provided with the second hand position groove 103, or the two hook portions 104 are respectively correspondingly provided with the first hand position groove 102 and the second hand position groove 103.

[0062] When replacing the consumable cartridge 20, the user inserts their fingers into the first hand position groove 102 and the second hand position groove 103. The force is directly applied to the engagement point between the hook portion 104 and the mating portion 21, easily disengaging the hook portion 104 from the mating portion 21, thus facilitating the removal of the consumable cartridge 20 from the receiving cavity 101. Furthermore, when installing the consumable cartridge 20, the hook portion 104 can also be easily engaged with the mating portion 21, reducing the difficulty of replacing and installing the consumable cartridge 20.

[0063] Please see Figure 2 and Figure 3 In some embodiments, the printer body 10 has a hook portion 104 on one side of the first hand position groove 102, and the hook portion 104 is located below the first hand position groove 102.

[0064] Understandably, when retrieving the consumable box 20, an upward force needs to be applied to the consumable box 20 to remove it from the receiving cavity 101. If the hook part 104 is located below the first hand position groove 102, when the user's finger enters the first hand position groove 102 and applies an upward force to retrieve the consumable box 20, this force is in the same direction as the locking force between the hook part 104 and the mating part 21. This can easily force the hook part 104 to disengage from the mating part 21, making it convenient to retrieve the consumable box 20 from the receiving cavity 101. However, if the hook part 104 is located to the side of the first hand position groove 102, i.e., not below the first hand position groove 102, the upward force applied to the consumable box 20 is insufficient to force the hook part 104 to disengage from the mating part 21, making it inconvenient to retrieve the consumable box 20 from the receiving cavity 101.

[0065] Please see Figure 2 , Figure 3 as well as Figure 5 In some embodiments, multiple hook portions 104 are provided, including a first hook portion 1041 and a second hook portion 1042. The first hook portion 1041 is located on the side of the printer body 10 where the first hand position groove 102 is provided, and the first hook portion 1041 is located below the first hand position groove 102. The second hook portion 1042 is located on the side of the printer body 10 where the second hand position groove 103 is provided, and the second hook portion 1042 is located below the second hand position groove 103.

[0066] Optionally, the inner side of the receiving cavity 101 is provided with two hook portions 104, namely a first hook portion 1041 and a second hook portion 1042. The first hook portion 1041 is located on the side of the printer body 10 where the first hand position groove 102 is provided, and the first hook portion 1041 is located below the first hand position groove 102. The second hook portion 1042 is located on the side of the printer body 10 where the second hand position groove 103 is provided, and the second hook portion 1042 is located below the second hand position groove 103.

[0067] When it is necessary to replace the consumable box 20, the thumb can be inserted into the first hand position groove 102, and the index, ring, and middle fingers can be inserted into the second hand position groove 103. The thumb, index, ring, and middle fingers can hold the consumable box 20, and the force applied by the thumb to the consumable box 20 can drive the first hook part 1041 to disengage from the corresponding mating part 21. The force applied by the index, ring, and middle fingers to the consumable box 20 can drive the second hook part 1042 to disengage from the corresponding mating part 21, which can further facilitate the removal of the consumable box 20 from the receiving cavity 101.

[0068] In addition, the first hook portion 1041 and the second hook portion 1042 are respectively disposed on opposite sides of the receiving cavity 101, so that the consumable box 20 can be more stably assembled in the receiving cavity 101, and the consumable box 20 can be prevented from detaching from the receiving cavity 101.

[0069] Please see Figure 4 and Figure 6 In some embodiments, the distance between the first hook portion 1041 and the bottom surface of the first hand position groove 102 is h1, and the distance between the second hook portion 1042 and the bottom surface of the second hand position groove 103 is h2, where h1 and h2 satisfy: h2 < h1.

[0070] Understandably, among the thumb, index finger, ring finger, and middle finger, the thumb has the greatest strength. In most cases, it is the thumb that applies force to remove the consumable box 20 from the receiving cavity 101. When h1 and h2 satisfy: h2 < h1, that is, the second hook part 1042 is closer to the bottom surface of the second hand position groove 103, the thumb can be inserted into the second hand position groove 103. The force applied by the thumb to the consumable box 20 can more easily disengage the second hook part 1042 from the corresponding mating part 21, thereby making it easier to remove the consumable box 20 from the receiving cavity 101.

[0071] Please see Figure 6 In some embodiments, the distance between the second hook portion 1042 and the bottom surface of the second hand position groove 103 is h2, and h2 satisfies: 1.5mm≤h2≤4mm.

[0072] Optionally, if h2 is less than 1.5mm, the engagement between the second hook portion 1042 and the corresponding mating portion 21 is not stable, resulting in the consumable box 20 not being securely assembled in the receiving cavity 101 and being prone to loosening. If h2 is greater than 4mm, the engagement between the second hook portion 1042 and the corresponding mating portion 21 is too secure, making it inconvenient to remove the consumable box 20. Therefore, when h2 satisfies: 1.5mm≤h2≤4mm, the consumable box 20 can be stably installed in the receiving cavity 101, and the consumable box 20 can be easily removed.

[0073] Please see Figure 2 In some embodiments, the printer body 10 includes a plurality of support portions 105, all of which are disposed on the bottom surface of the receiving cavity 101 and are distributed around the center line of the receiving cavity 101. The support portions 105 are used to support the bottom of the consumable box 20.

[0074] Optionally, the cavity 101 is provided with a plurality of support parts 105, and the plurality of support parts 105 are all disposed on the bottom surface of the cavity 101. The bottom surface of the cavity 101 is rectangular. The plurality of support parts 105 are respectively located at the four corners of the bottom surface of the cavity 101. When the consumable box 20 is assembled in the cavity 101, the plurality of support parts 105 can support the bottom of the consumable box 20, so that the consumable box 20 can be stably installed in the cavity 101, and the contact area between the consumable box 20 and the cavity 101 can be reduced, making it easier to take out the consumable box 20.

[0075] Please see Figure 2 In some embodiments, the support 105 is provided with one of a positioning part 106 and a positioning hole, and the bottom surface of the consumable box 20 is provided with the other of a positioning part 106 and a positioning hole. The positioning part 106 is used to be inserted into the positioning hole.

[0076] Optionally, the positioning part 106 is a positioning post, the top surface of the support part 105 is provided with a positioning post, and the bottom surface of the consumable box 20 is provided with a positioning hole. When the consumable box 20 is assembled into the receiving cavity 101, the positioning post can be inserted into the positioning hole to position the consumable box 20. This ensures that the consumable box 20 is correctly installed in the receiving cavity 101, so that the printer 100 can use the consumables in the consumable box 20 to complete the printing work normally, and prevents the consumable box 20 from being installed incorrectly.
