Description

Technical Field

[0001] The present invention relates to the field of packaging and transportation, and particularly to a print head packaging box for air transportation. Background Art

[0002] The description in this part only provides background information related to the disclosure of the present invention and does not constitute prior art.

[0003] Special moisturizing liquid needs to be injected into the interior of an inkjet print head. Its main function is to keep the nozzles moist, prevent ink from drying up and causing blockages, thereby ensuring print quality and the service life of the print head. However, during air transportation, due to the significant air pressure difference between high altitude and the ground, a large pressure difference will be generated between the interior of the print head and the external environment. This pressure difference may cause the moisturizing liquid to leak out from the nozzles or seals of the print head, which will not only result in the loss of the moisturizing liquid, but may also contaminate the packaging and even damage the print head. Therefore, in order to effectively prevent the leakage of the moisturizing liquid during transportation, the present application invents a print head packaging box for air transportation, which can not only keep the nozzles of the print head moist, but also prevent the leakage of the moisturizing liquid.

[0004] It should be noted that the introduction of the technical background above is only for the convenience of clearly and completely explaining the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present invention. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a print head packaging box for air transportation.

[0006] To solve the above technical problem, the present invention provides a print head packaging box for air transportation, which includes an upper shell and a lower shell that are mutually covered. An accommodation space for placing the print head is formed inside the upper shell and the lower shell. A nozzle protection member is installed inside the lower shell. The nozzle protection member includes a nozzle protection outer shell and an ink absorption pad installed inside the nozzle protection outer shell. The surface of the ink absorption pad faces upward. A spring is also connected between the nozzle protection member and the bottom surface of the lower shell. The upper end of the spring abuts against the lower surface of the nozzle protection outer shell, and the lower end of the spring abuts against the bottom surface of the lower shell. When the upper shell and the lower shell are mutually covered, the spring is compressed between the bottom surface of the lower shell and the bottom of the nozzle protection outer shell, and the nozzles of the print head abut against the ink absorption pad.

[0007] Preferably, the lower end of the print head is hermetically connected to the nozzle protection outer shell, and the ink channels of the print head and the ink absorption pad are filled with moisturizing liquid.

[0008] Preferably, the lower end of the print head and the nozzle protection housing are sealed by a sealing ring. When the upper shell and the lower shell are closed, the sealing ring is pressed between the lower end of the print head and the nozzle protection housing under the elastic force of the spring.

[0009] Preferably, a sponge bin is further installed in the lower shell. A sponge cavity with a sponge installed therein is provided in the sponge bin. The outer surface of the sponge cavity includes an elastic membrane. The sponge bin is in communication with the inside of the nozzle protection housing.

[0010] Preferably, the elastic membrane is made of PVC material. The sponge bin is connected to the nozzle protection housing through a hose.

[0011] Preferably, a first installation portion and a second installation portion are respectively provided on two side surfaces of the nozzle protection housing. A first installation wall and a second installation wall which are vertically arranged are further provided at the bottom of the lower shell. The first installation portion is installed on the first installation wall, and the second installation portion is installed on the second installation wall. When the nozzle protection part moves downward against the elastic force of the spring or moves upward under the elastic force of the spring under an external force, the first installation portion can move up and down along the first installation wall, and the second installation portion can move up and down along the second installation wall.

[0012] Preferably, a plurality of elastic pins are further provided at the lower end of the sponge bin. A plurality of installation holes for inserting the elastic pins are provided at the bottom of the lower shell. The elastic pins are inserted into the installation holes to fix the sponge bin.

[0013] Preferably, the lower end of the elastic pin is a triangular head. A plurality of limiting feet are further provided at the lower end of the sponge bin. When the triangular head is completely inserted into the installation hole, the lower end of the limiting foot abuts against the upper surface of the bottom surface of the lower shell, and the upper surface of the triangular head abuts against the lower surface of the bottom surface of the lower shell.

[0014] Preferably, the limiting foot is an L-shaped structure. The lower end portion of the limiting foot is bent to form a horizontally extending portion, and this horizontally extending portion is used to abut against the upper surface of the bottom surface of the lower shell.

[0015] Preferably, a circular lower spring installation portion is further provided at the bottom of the lower shell. A circular upper spring installation portion is provided at the bottom of the nozzle protection housing. The upper end of the spring is installed in the upper spring installation portion, and the lower end of the spring is installed in the lower spring installation portion.

[0016] With the above technical solutions, the beneficial effects of the present invention are as follows:

[0017] The print head packaging box for air transportation according to the present invention can hold the print head inside the packaging box. When there is a change in internal and external pressure during transportation, the moisturizing liquid will flow out from the print head nozzles into the ink absorption pad, thereby effectively preventing the leakage of the moisturizing liquid. There is a sealing structure between the print head and the nozzle protection housing. When the upper shell and the lower shell are closed, the upper shell will apply a downward pressure to overcome the elastic force of the spring, causing the nozzle protection housing to move downward. The nozzle part of the print head presses on the ink absorption pad, and at the same time, the sealing ring is pressed tightly between the nozzle protection housing and the print head to form a reliable seal. The elastic force of the spring ensures that the sealing ring is always under uniform pressure, preventing ink leakage or the entry of external contaminants. In addition, the packaging box of the present application is also provided with a sponge chamber. The surface of the sponge cavity has an elastic membrane. The lower end of the print head is hermetically connected to the nozzle protection housing. When the internal and external pressure difference increases, the moisturizing liquid in the print head will flow into the nozzle protection housing. Once the moisturizing liquid in the nozzle protection housing reaches saturation, it will enter the sponge chamber through a hose. Since the elastic membrane of the sponge chamber has elasticity, it can adjust the volume of the sponge cavity, thereby achieving the balance of internal and external pressures.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] It should be noted that in the description of the present invention, the terms "first", "second", etc. are only used for descriptive purposes and to distinguish similar objects, and there is no sequence between them, nor can they be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0034] As Figure 1 shown, it is a packaging box for installing a print head of the present application, including an upper shell 1 and a lower shell 2 that are mutually covered. An accommodation space is formed inside the upper shell 1 and the lower shell 2, and the print head is installed in the accommodation space. As Figure 2As shown, the upper shell 1 of the present application has snap 12 assemblies on opposite sides of the lower edge of the upper shell 1. The snap 12 assembly includes a pressing plate 11. The lower side edge of the pressing plate 11 extends downward to form two snaps 12. The pressing plate 11 is fixedly connected to the edge of the upper shell 1 through a connecting portion 122. The connecting portion 122 is a thin-walled structure. When the pressing plate 11 is pressed inward, the snaps 12 can spring outward. The inner side of the lower end of the snap 12 has an upper sliding contact surface 121. The upper sliding contact surface 121 is an inclined surface. In a preferred embodiment, the upper sliding contact surface 121 is an inclined surface with an angle between 30° and 45° with the vertical plane.

[0035] As Figure 3 shown, the lower shell 2 of the present application has blocks 21 corresponding to the snap 12 assemblies on opposite sides of the upper edge of the lower shell 2. The outer side surface of the block 21 is a lower sliding contact surface 211 that cooperates with the upper sliding contact surface 121. The lower sliding contact surface 211 is also an inclined surface, and the inclination angle is the same as that of the upper sliding contact surface 121.

[0036] When the upper shell 1 and the lower shell 2 are closed, the upper sliding contact surface 121 of the snap 12 and the lower sliding contact surface 211 of the block 21 are pressed against each other. The snap 12 springs open under the pressure until the snap 12 is stuck on the block 21, locking the upper shell 1 and the lower shell 2. When it is necessary to separate the upper shell 1 and the lower shell 2, press the pressing plate 11 inward. The snap 12 at the lower end of the pressing plate 11 will spring outward and disengage from the block 21, thereby realizing the separation of the upper shell 1 and the lower shell 2.

[0037] As Figure 7 shown, a nozzle protection member 3 is also installed in the lower shell 2. As Figure 8 shown, the nozzle protection member 3 includes a nozzle protection outer shell 31 and an ink absorption pad 32 installed in the nozzle protection outer shell 31. The surface of the ink absorption pad 32 faces upward.

[0038] A spring 5 is also connected between the bottom surface of the nozzle protection member 3 and the bottom surface of the lower shell 2. The upper end of the spring 5 abuts against the lower surface of the nozzle protection outer shell 31, and the lower end of the spring 5 abuts against the bottom surface of the lower shell 2.

[0039] First mounting portions 33 and second mounting portions 34 are respectively provided on both side surfaces of the nozzle protection outer shell 31. As Figures 4 - 6As shown, a first mounting wall 24 and a second mounting wall 25 are further provided at the bottom of the lower shell 2, and the first mounting wall 24 and the second mounting wall 25 are vertically arranged. The first mounting portion 33 is mounted on the first mounting wall 24 and can move up and down along the first mounting wall 24. The second mounting portion 34 is mounted on the second mounting wall 25 and can move up and down along the second mounting wall 25.

[0040] A circular lower spring mounting portion 23 is further provided at the bottom of the lower shell 2, a circular upper spring mounting portion 35 is provided at the bottom of the nozzle protection outer shell 31, the upper end of the spring is mounted in the upper spring mounting portion 35, and the lower end of the spring is mounted in the lower spring mounting portion 23.

[0041] When the nozzle protection member 3 moves downward against the elastic force of the spring or moves upward under the action of the elastic force of the spring under an external force, the first mounting portion 33 can move up and down along the first mounting wall 24, and the second mounting portion 34 can move up and down along the second mounting wall 25.

[0042] When the print head is installed in the packaging box, the nozzle just abuts against the ink absorbing pad 32, and the ink absorbing pad 32 can absorb the ink that may remain in the nozzle, preventing the ink from drying up and blocking the nozzle.

[0043] As Figure 7 shown, a sponge bin 4 is further installed in the lower shell 2. As Figure 12 shown, a sponge cavity 43 is provided in the sponge bin 4, and a sponge can be installed in the sponge cavity 43.

[0044] The outer surface of the sponge cavity 43 includes an elastic membrane, and the elastic membrane can be made of PVC material.

[0045] The sponge bin 4 is communicated with the nozzle protection outer shell 31 through a hose 6.

[0046] The lower end of the print head is hermetically connected to the nozzle protection outer shell 31. When the internal and external pressure difference increases, the moisturizing liquid in the print head will flow into the nozzle protection outer shell 31. Once the moisturizing liquid in the nozzle protection outer shell 31 reaches saturation, it will enter the sponge bin 4 through the hose 6. Since the elastic membrane of the sponge bin 4 has elasticity, it can adjust the volume of the sponge cavity 43, thereby achieving the balance of internal and external pressures.

[0047] Specifically, the lower end of the print head is sealed with the nozzle protection housing 31 through a sealing ring. When the upper shell 1 and the lower shell 2 are closed, the upper shell 1 will apply a downward pressure, overcoming the elastic force of the spring, causing the nozzle protection housing 31 to move downward. The nozzle part of the print head presses on the ink absorption pad 32, and at the same time, the sealing ring is pressed tightly between the nozzle protection housing 31 and the print head to form a reliable seal. The elastic force of the spring ensures that the sealing ring is always under uniform pressure, preventing ink leakage or entry of external contaminants.

[0048] As Figure 12 shown, a plurality of elastic pins 41 are further provided at the lower end of the sponge bin 4. Correspondingly, a plurality of mounting holes 26 for inserting the elastic pins 41 are provided at the bottom of the lower shell 2. The lower end of the elastic pin 41 is a triangular head, and the triangular shape helps to play a guiding role when inserting into the mounting hole 26, enabling the pin to more easily align and enter the hole. When the triangular head of the elastic pin 41 is completely inserted into the mounting hole 26, the elastic pin 41 will return to its original state, and the triangular head will be stuck on the lower side of the mounting hole 26 to form a firm connection.

[0049] A plurality of limiting feet 44 are further provided at the lower end of the sponge bin 4. When the triangular head is completely inserted into the mounting hole 26, the lower end of the limiting foot 44 abuts against the upper surface of the bottom surface of the lower shell 2. The limiting feet 44 and the elastic pins 41 are used in cooperation to limit the insertion depth of the sponge bin 4 and determine the installation position of the sponge bin 4. In a preferred embodiment, the limiting foot 44 is an L-shaped structure, and the lower end of the limiting foot 44 is bent to form a horizontally extending portion, which is used to abut against the upper surface of the bottom surface of the lower shell 2. The connection mode of the elastic pin 41, the limiting foot 44 and the sponge bin 4 can be integrally formed, that is, the elastic pin 41, the limiting foot 44 and the sponge bin 4 are directly made into a whole through processes such as injection molding and compression molding during the manufacturing process.

[0050] The above-described embodiments are only preferred embodiments cited to fully illustrate the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or transformations made by those skilled in the art on the basis of the present invention are all within the protection scope of the present invention. The protection scope of the present invention is subject to the claims.
