[0017] From the above description of the present invention and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the present invention and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:
[0018] 1. Option 1 and its preferred embodiment provide a protective case suitable for accommodating a printer, comprising a main body and a cover. The main body is provided with a receiving groove, which is suitable for accommodating the printer to achieve a certain degree of protection. The receiving groove is provided with a through hole, which is suitable for exposing at least the paper outlet of the printer to ensure that when the through hole is open, the printer can print paper without interfering with the cover.
[0019] The cover is flexible and suitable for opening or closing relative to the main body. The cover is provided with a wrapping groove. The groove wall of the wrapping groove is suitable for covering the through hole when the cover is in the closed state, thereby preventing water or dust from entering the interior of the printer through the paper outlet, and the groove wall of the wrapping groove wraps the main body to achieve the fixation of the cover and the main body. Due to the wrapping characteristics, the gap at the connection between the cover and the main body is small and the sealing is good. It is not easy for water or dust to enter the through hole from the connection between the cover and the main body, affecting the sealing of the printer.
[0020] 2. In the second solution and its preferred embodiment, the two ends of the connecting belt respectively connect the main body and the cover body, thereby preventing the cover body from being lost relative to the main body. At the same time, since the connecting belt is flexible, the movement of the cover body relative to the main body can be achieved through the deformation of the flexible belt.
[0021] 3. In the third solution and its preferred embodiment, the main body, cover and connecting belt are integrally formed, which facilitates processing and reduces mold costs.
[0022] 4. In the fourth solution and its preferred embodiment, if the cover is closed relative to the main body, the wall of the wrapping slot is in contact with the through hole. In this state, if printing is performed, the paper will be blocked by the wall of the wrapping slot, and the printed paper cannot be smoothly ejected from the printer. Therefore, the cover must usually be opened to perform printing operations. If it is raining, there is a possibility that water will enter the printer through the paper outlet during printing. This solution also provides a clearance slot in the cover. The notch of the clearance slot is formed in the wall of the wrapping slot. When the cover is closed, the notch of the clearance slot faces the paper outlet, leaving space for the printer to eject paper. This allows printing to be performed even when the cover is closed. After printing, the paper enters the clearance slot, thereby reducing the possibility of water entering the printer 2 during printing.
[0023] 5. In Scheme 5 and its preferred embodiments, the printer has waterproof or dustproof parts, such as the charging port, USB port, and gaps with waterproof or dustproof functions, which have certain waterproof and dustproof functions. During normal use, there is no need to achieve the corresponding protection effect through the sealing of the protective shell. However, during daily use, if the printer is not exposed from the protective shell, it is necessary to take out the printer before using it, which is more troublesome, and the protective shell is easily damaged by taking the printer out and putting it in and out multiple times. This scheme also provides an exposure hole through the accommodating groove. The exposure hole is suitable for exposing the waterproof or dustproof part of the printer, so that the corresponding function can be used without taking out the printer.
[0024] 6. In Option 6 and its preferred embodiment, in order to save costs, the thickness of the groove wall of the wrapping groove is usually not set too large, which results in a small operating area and makes it more difficult to open the cover body. An operating part protruding outward from the groove wall of the wrapping groove is provided on the cover body to facilitate user operation and open the cover body.
[0025] 7. In solution seven and its preferred embodiment, the main body is flexible, and the accommodating groove is suitable for wrapping the printer, so as to adapt to printers of more sizes, and after wrapping the printer, the printer does not shake.
[0026] 8. In solution eight and its preferred embodiment, a printing assembly includes a printer and the above-mentioned protective shell, and has the beneficial effects brought by the above-mentioned protective shell.
[0027] 9. In Option 9 and its preferred embodiment, the printer further includes a paper storage bin and a paper bin cover adapted to be opened or closed relative to the opening of the paper storage bin, and the through hole is further adapted to expose the paper bin cover so as to facilitate paper replacement without removing the printer.
[0028] 10. In solution 10 and its preferred embodiment, the printer is suitable for being placed in the receiving groove through the through hole, thereby reducing the complexity of the protective shell and facilitating the processing of the protective shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] refer to Figures 1-9 , a printing component, including a printer 2 and a protective shell 1.
[0047] refer to Figure 3 、 Figure 5 The printer 2 includes a paper outlet 21, a paper storage bin 22, a paper bin cover 23, a printing element and a waterproof or dustproof part. The paper storage bin 22 is used to store printing paper. The printing element is suitable for printing the printing paper in the paper storage bin 22, and outputting the printed paper from the paper outlet 21. The paper bin cover 23 is suitable for opening or closing the opening relative to the paper storage bin 22. The paper bin cover 23 and the shell of the printer 2 can change between two states by a rotating connection, a sliding connection or a detachable connection, thereby realizing the replacement of printing paper. The waterproof or dustproof part refers to the part of the printer that has a certain waterproof and dustproof effect even if it is exposed to the protective shell 1, such as the charging port 24 with a silicone plug, the USB port, the gap with waterproof or dustproof function, etc.
[0048] refer to Figure 2The protective shell 1 is suitable for accommodating the printer 2. The protective shell 1 includes a body 11, a cover 12 and a connecting belt 13. In this embodiment, the body 11, the cover 12 and the connecting belt 13 are integrally formed and are all flexible.
[0049] The body 11 is roughly a rectangular parallelepiped (its shape roughly corresponds to that of the printer 2). The body 11 is provided with a receiving groove 111, which is suitable for receiving the printer 2. Preferably, the body 11 is flexible so that the receiving groove 111 is suitable for wrapping the printer 2 so that the printer 2 does not shake in the receiving groove 111. At the same time, for some printers 2 with key operation functions, such as turning the machine on and off by a key, when the printer 2 needs to be operated by a key, the body 11 can be pressed to deform the body 11, thereby triggering the key on the printer 2 so that the printer 2 is operated. The receiving groove 111 is provided with a through hole 112 and an exposure hole (not shown in the figure). The through hole 112 is open at the top of the body 11 and on one side near the connecting belt 13. The printer 2 is suitable for being placed in the receiving groove 111 through the through hole 112, and the paper outlet 21 and the paper bin cover 23 are exposed through the through hole 112. There are a plurality of exposure holes, which are suitable for exposing the waterproof or dustproof part of the printer 2.
[0050] The cover 12 is provided with a wrapping groove 121. The cover 12 is opened or closed relative to the body 11. For details, refer to Figure 6-Figure 8 The cover 12 is flexible so that the wall of the wrapping groove 121 is suitable for wrapping the body 11 and covering the through hole 112 when the cover 12 is in the closed state. In this embodiment, the bottom wall and the side wall of the wrapping groove 121 cover the through hole 112. Preferably, in other embodiments, the wall of the wrapping groove 121 can also cover the exposure hole to further achieve sealing at the exposure hole. Figure 4 、 Figure 5 When the cover 12 is in the open state, the through hole 112 of the wall of the wrapping slot 121 is open to facilitate operations such as printing out paper and changing paper. Figure 9 The cover 12 is further provided with a clearance slot 122. The slot opening of the clearance slot 122 is opened on the slot wall of the wrapping slot 121. When the cover 12 is in the closed state, the slot opening of the clearance slot 122 faces the paper outlet 21, so that the printer 2 can also print in the closed state. The paper fed from the paper outlet 21 enters and is temporarily stored in the clearance slot 122. The clearance slot 122 can be understood as a space between the slot wall of the wrapping slot 121 and the through hole 112 for accommodating printing paper. Its shape and size can be the same as or different from the shape and size of the wrapping slot 121. Figure 2 The cover body 12 is provided with an operating portion 123 protruding outward from the groove wall of the wrapping groove 121. The operating portion 123 is suitable for being pushed to drive the cover body 12 to open relative to the main body 11. Anti-slip grooves can be provided on the operating portion 123 to prevent sliding when force is applied.
[0051] refer to Figure 2 The connecting belt 13 is flat and flexible, and the two ends of the connecting belt 13 are respectively connected to the main body 11 and the cover body 12.
[0052] During installation, the printer 2 is placed into the receiving groove 111 of the body 11 through the through hole 112 , and the paper outlet 21 and the paper compartment cover 23 of the printer 2 are exposed through the through hole 112 of the receiving groove 111 .
[0053] When waterproofing or dustproofing is required, closing the cover 12 allows the cover's wrapping groove 121 to wrap around the body 11, thereby maintaining the cover's closure. At the same time, the through-hole 112 is shielded by the cover's wrapping groove 121, preventing water and dust from entering. If printing is required without the cover 12's clearance groove 122, the cover 12 is opened to expose the through-hole 112, allowing printing to proceed. If printing is required with the cover 12's clearance groove 122, printing can be performed first, and then the cover 12 can be opened to remove paper.
[0054] Compared with the prior art, this embodiment has the following beneficial effects:
[0055] In an exemplary embodiment, a protective shell 1 is suitable for accommodating a printer 2, including a main body 11 and a cover 12. The main body 11 is provided with a accommodating groove 111, which is suitable for accommodating the printer 2 to achieve a certain protective effect. The accommodating groove 111 is provided with a through hole 112, which is at least suitable for exposing the paper outlet 21 of the printer 2 to ensure that when the through hole 112 is open, the printer 2 can print paper without interfering with the cover 12.
[0056] The cover 12 is flexible and suitable for opening or closing relative to the main body 11. The cover 12 is provided with a wrapping groove 121. The groove wall of the wrapping groove 121 is suitable for covering the through hole 112 when the cover 12 is in the closed state, thereby preventing water or dust from entering the interior of the printer 2 from the paper outlet 21, and the groove wall of the wrapping groove 121 wraps the main body 11 to achieve the fixation of the cover 12 and the main body 11. Due to the wrapping characteristics, the gap at the connection between the cover 12 and the main body 11 is small and the sealing is good. It is not easy for water or dust to enter the through hole 112 from the connection between the cover 12 and the main body 11, affecting the sealing of the printer 2.
[0057] In an exemplary embodiment, the two ends of the connecting belt 13 respectively connect the main body 11 and the cover body 12, thereby preventing the cover body 12 from being lost relative to the main body 11. At the same time, since the connecting belt 13 is flexible, the movement of the cover body 12 relative to the main body 11 can be achieved through the deformation of the flexible belt.
[0058] In an exemplary embodiment, the main body 11, the cover 12 and the connecting belt 13 are integrally formed, which facilitates processing and reduces mold costs.
[0059] In an exemplary embodiment, when the cover 12 is closed relative to the body 11, the wall of the wrapping slot 121 is in contact with the through hole 112. In this state, if printing is performed, the paper will be blocked by the wall of the wrapping slot 121, and the printed paper cannot be smoothly ejected from the printer 2. Therefore, the cover 12 usually needs to be opened to perform printing operations. If it is raining, there is a possibility that water will enter the printer 2 through the paper outlet 21 during printing. In this solution, the cover 12 is further provided with a clearance slot 122. The notch of the clearance slot 122 is opened in the wall of the wrapping slot 121. When the cover 12 is in the closed state, the notch of the clearance slot 122 faces the paper outlet 21 to leave clearance space for the printer 2 to output paper. This allows printing to be performed even when the cover 12 is closed. After printing, the paper enters the clearance slot 122, thereby reducing the possibility of water entering the printer 2 during printing.
[0060] In an exemplary embodiment, the printer 2 has waterproof or dustproof parts, such as the charging port 24, the USB port, and gaps with waterproof or dustproof functions, which have certain waterproof and dustproof functions. During normal use, there is no need to achieve the corresponding protection effect through the sealing of the protective shell 1. However, during daily use, if it is not exposed to the protective shell 1, the printer 2 needs to be taken out before it can be used, which is more troublesome, and the protective shell 1 is easily damaged by taking and putting the printer 2 in and out multiple times. This solution also provides an exposure hole through the accommodating groove 111. The exposure hole is suitable for exposing the waterproof or dustproof part of the printer 2, so that the corresponding function can be used without taking out the printer 2.
[0061] In an exemplary embodiment, in order to save costs, the thickness of the groove wall of the wrapping groove 121 is usually not set too large, which results in a small operating area and makes it more difficult to open the cover body 12. An operating portion 123 protruding outward from the groove wall of the wrapping groove 121 is provided on the cover body 12 to facilitate user operation and facilitate opening of the cover body 12.
[0062] In an exemplary embodiment, the body 11 is flexible, and the accommodating groove 111 is suitable for wrapping the printer 2 so as to accommodate printers 2 of more sizes. After wrapping the printer 2, the printer 2 does not shake.
[0063] In an exemplary embodiment, a printing assembly includes a printer 2 and the above-mentioned protective shell 1, and has the beneficial effects brought by the above-mentioned protective shell 1.
[0064] In an exemplary embodiment, the printer 2 further includes a paper storage bin 22 and a paper bin cover 23 adapted to be opened or closed relative to an opening of the paper storage bin 22 , and the through hole 112 is further adapted to expose the paper bin cover 23 so as to facilitate paper replacement without removing the printer 2 .
[0065] In an exemplary embodiment, the printer 2 is suitable for being placed into the receiving groove 111 through the through hole 112 , thereby reducing the complexity of the protective shell 1 and facilitating the processing of the protective shell 1 .
[0066] The above description and embodiments are used to explain the scope of protection of the utility model, but do not constitute a limitation on the scope of protection of the utility model. Based on the enlightenment of the utility model or the above embodiments, modifications, equivalent replacements, or other improvements to the embodiments of the utility model or part of the technical features thereof that can be obtained by ordinary technicians in this field through logical analysis, reasoning, or limited experiments in combination with common knowledge, ordinary technical knowledge in this field and / or existing technology should be included in the scope of protection of the utility model.
