Description

Technical Field

[0001] The present application relates to the technical field of film applicators, and more specifically, to a dust removal film applicator and a film applicator kit for watches. Background Art

[0002] In order to protect the screen of the watch, for example, the screen of a smart watch needs to be touched frequently, users usually stick a layer of film on the surface of the watch screen to prevent the touch screen from being scratched. During the film application process, in order to pursue the smoothness of the lines and avoid the generation of bubbles, so that the appearance of the terminal device remains beautiful, a film applicator is usually used to assist the user in precise positioning and film application, so that the film application effect can be improved.

[0003] Some applicators currently on the market use pull-out protective films to apply film to watches. During the applicator process, the smartwatch is first placed in the applicator with the screen facing up. The pull-out protective film is then attached to the case, positioning it above the smartwatch's screen. However, due to the tearing of the release layer during the pull-out process, a certain gap between the film and the smartwatch's screen is required. This gap prevents the protective film from expanding or contracting when pressed down to adhere to the smartwatch's screen surface. Due to the lack of elasticity in the case, the protective film's layer can be easily bent or damaged during the compression process, leading to failed applicators.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0005] The purpose of the present application is to provide a dust removal film applicator and a film applicator kit for watches, which solves the problem in the prior art that the protective film has no room for expansion and contraction during the extrusion process and is easily bent or damaged.

[0006] To achieve the above objectives, the technical solution adopted in this application is:

[0020] Optionally, the dust removal film applicator further includes an extrusion piece, which is movably arranged on the housing;

[0021] The protective film connected to the first limiting member and the second limiting member is pressed by pushing the pressing member.

[0022] Optionally, a guide rail is provided on the side surface of the housing in the second direction;

[0025] Optionally, a turning groove is provided on the side of the housing, wherein the turning groove forms a sliding outlet at one end in the first direction and is closed at the other end to form a turning position, and the turning groove is further provided with an inlet and outlet opening facing upward;

[0026] The sliding frame includes: two guide posts arranged on the inner wall along a first direction and spaced apart, and a position-limiting matching surface spaced a predetermined distance from the guide posts, wherein a guide matching position is formed between the guide posts and the position-limiting matching surface, and the guide matching position cooperates with the housing to enable the sliding frame to slide in a direction on the housing;

[0027] When the sliding frame moves into the turning groove, one of the guide posts is located on the turning position and serves as a rotation axis, so that the other guide post rotates out from the inlet and outlet to turn the sliding frame from the top of the shell to the side of the shell.

Before film application begins, the elastic member is elastically extended to separate the protective film from the smartwatch screen by a predetermined distance, thereby allowing the tear-off layer of the protective film to fall off within the gap during the pull-out process, and facilitating the tear-off layer to remove dust from the smartwatch screen within the gap during the pull-out process. After the tear-off layer is pulled out, the film layer is aligned with the smartwatch screen, and the elastic member is compressed by the protective film, causing the elastic member to contract. This allows the protective film to have room to deform downward, allowing the film layer to smoothly move downward and contact the smartwatch screen. The film layer is not significantly squeezed and deformed during the downward movement, which could cause damage, thereby making the film application process smoother.

[0043] Example 1

[0044] like Figure 1 、 Figure 3 As shown, this embodiment provides a dust removal and film applicator for watches, which is used to apply a film to the screen of a watch. The watch in this embodiment can be an electronic watch such as a smart watch 10, a sports watch, etc. To facilitate the structural description of this embodiment, the smart watch 10 is used as an example for explanation. The smart watch 10 can be round or square. To facilitate the structural description, this embodiment takes the direction of the strap as the first direction, the direction perpendicular to the first direction in the horizontal plane as the second direction, and the thickness direction as the up-down direction. The first direction, second direction, and up-down direction are all described in this manner as a reference. According to actual needs, the first direction and the second direction can be swapped to achieve the effect of this solution.

[0045] like Figure 1 、 Figure 2 As shown, the dust removal film applicator for watches in this embodiment is used to adhere the film portion of the protective film 20 to the screen of the smart watch 10, as shown in FIG. Figure 2 、 Figure 3 、 Figure 4 As shown, the protective film 20 can take various forms. For example, one form mainly includes: a film layer 22, a positioning release layer 21, and a tear-off release layer 23. The film layer 22 (the film that is actually attached to the screen surface) is used to be attached to the surface of the smart watch 10, thereby protecting the screen of the smart watch 10; the positioning release layer 21 is detachably provided on one side of the film layer 22, and is used to be connected to the dust removal film applicator used for the watch. The tear-off release layer 23 is provided on the side of the film layer 22 away from the positioning release layer 21 and facing the smart watch 10. During use, the positioning release layer 21 and the tear-off release layer 23 are both pulled away from the film layer 22, leaving only the film layer 22 adhered to the screen surface of the smart watch 10.

[0046] like Figure 1 、 Figure 2 、 Figure 3 As shown, the dust removal and film applicator for watches of this embodiment mainly includes a shell 100, an elastic and retractable member 200, a first limiting member 300 and a second limiting member 400. The shell 100 can be set to a square structure, and the shell 100 is placed flat when in use. A positioning chamber 163 is provided in the shell 100, and the positioning chamber 163 is open upward to form an open side. The positioning chamber 163 is used to accommodate and limit the smart watch 10 to be filmed. The first end of the shell 100 in the first direction is provided with a first limiting member 300, and the second end of the surface of the shell 100 in the first direction is provided with an air avoidance hole 120. The first end can be the rear end, and the second end can be the front end. The elastic and retractable member 200 is provided in the air avoidance hole 120, and the elastic and retractable member 200 is integrally formed with the shell 100. The elastic member 200 is located outside the positioning chamber 163. A second limiting member 400 is provided on the elastic member 200. The elastic member 200 can be extended and retracted along a first direction to drive the second limiting member 400 to move along the first direction. The first limiting member 300 and the second limiting member 400 are respectively used to connect to the protective film 20. Specifically, the first limiting member 300 and the second limiting member 400 are connected to the positioning release layer 21 of the protective film 20 at the rear and front ends, respectively, thereby limiting the connection between the protective film 20 and the housing 100, with the protective film 20 facing upward, and the smart watch 10 located below the protective film 20. The elastic expansion member 200 is elastically extended to move the second limiting member 400 away from the first limiting member 300, thereby stretching the protective film 20 so that the protective film 20 is separated from the screen of the smart watch 10 by a predetermined distance. That is, when the two ends of the positioning release layer 21 of the protective film 20 are connected to the first limiting member 300 and the second limiting member 400, the elastic expansion member 200 is opened to tighten the protective film 20, thereby creating a dust removal space between the protective film 20 and the screen of the smart watch 10, making it convenient to remove dust from the screen of the smart watch 10 within the dust removal space during the pulling out process of the release layer, thereby achieving a dust removal effect. When applying the film, by squeezing the protective film 20, the elastic expansion member 200 is forced to contract so that the film layer 22 on the protective film 20 has a downward movement, so that the film layer 22 of the protective film 20 moves smoothly downward and contacts the screen of the smart watch 10. The film layer 22 will not be greatly squeezed and deformed during the downward movement, resulting in damage, making the film application process smoother.

[0047] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, in the specific structure of the shell 100, the upper surface of the shell 100 is provided with an accommodating inner cavity 110, which is open upward to form an open side, and a body limiting portion 160 can be replaceably provided in the accommodating inner cavity 110, and a positioning chamber 163 is formed by the body limiting portion 160, and the positioning chamber 163 is used to accommodate and limit the smart watch 10 to be pasted with a film; the body limiting portion 160 can be configured in plurality, and the plurality of body limiting portions 160 have different specifications and sizes, and the structures of the connection between them and the positioning chamber 163 are the same, so that when in use, one of the body limiting portions 160 is selected to match the smart watch 10 to be pasted with a film, thereby stably limiting the smart watch 10. By providing a housing cavity 110 within the housing 100, the housing cavity 110 can be connected to a housing stopper 160 of different sizes. After the housing stopper 160 matching the specifications of the smartwatch 10 to be film-applied is connected to the housing cavity 110, a positioning chamber 163 matching the smartwatch 10 is formed on the housing 100. The smartwatch 10 is placed into the positioning chamber 163 for positioning, thereby keeping the smartwatch 10 in place. The protective film 20 is then connected to the housing 100 via the first and second stoppers, so that the protective film 20 is positioned above and spaced from the smartwatch 10. This aligns the protective film 20 with the screen of the smartwatch 10 below, and the protective film 20 is pressed downward to adhere to the screen of the smartwatch 10. By making the housing stopper 160 interchangeable, it can be adapted to different specifications of smartwatches 10, improving the adaptability of the film applicator and enhancing its practicality, making it both easier to manufacture and more user-friendly.

[0048] like Figure 2 、 Figure 4 As shown, a strap accommodating groove 111 is further provided on the surface of the shell 100 of this embodiment. The strap accommodating groove 111 is arranged along the length direction and is connected to the accommodating inner cavity 110, and the strap accommodating groove 111 can pass through the entire shell 100 in the length direction, so that when the smart watch 10 is applied with a film, the strap can be placed in the strap accommodating groove 111.

[0049] like Figure 1 、 Figure 2 、 Figure 4As shown, the body limiting portion 160 in this embodiment specifically includes a first limiting block 161 and a second limiting block 162, which are respectively disposed on opposite sides of the accommodating cavity 110. To avoid interference with the placement of a watch strap, the first limiting block 161 and the second limiting block 162 are respectively disposed on opposite sides of the accommodating cavity 110 in the second direction, with the space between them facilitating the placement of the watch strap. Both the first limiting block 161 and the second limiting block 162 are provided with limiting inner walls, which, when positioned opposite each other, form a positioning chamber 163. When the smart watch 10 is placed between the two limiting inner walls, the limiting inner walls abut against the sides of the smart watch 10, thereby limiting the front, back, left, and right side positions of the smart watch 10. If the body limiting part 160 is replaced, it is only necessary to replace the corresponding first limiting block 161 and the second limiting block 162. The body limiting parts 160 of different specifications mainly have different structures and sizes of the limiting inner wall surfaces of the first limiting block 161 and the second limiting block 162.

[0050] like Figure 1 、 Figure 2 As shown, further, the elastic telescopic member 200 of this embodiment specifically includes a bending portion 210 and a supporting platform 220. The bending portion 210 is located in the air avoidance hole 120, and one end thereof is connected to the inner wall of the air avoidance hole 120. The supporting platform 220 is connected to the end of the bending portion 210 away from the first limiting member 300. The second limiting member 400 is arranged on the supporting platform 220. The supporting platform 220 moves relative to the shell 100 through the bending of the bending portion 210 and realizes expansion and contraction in the first direction. When the second limiting member 400 and the first limiting member 300 are connected to the protective film 20, the bending portion 210 is compressed by squeezing the protective film 20, and the supporting platform 220 moves toward the direction close to the first limiting member 300. In this way, the distance between the first limiting member 300 and the second limiting member 400 in the first direction becomes smaller, so that the protective film 20 has a downward movement margin. The bending portion 210 may adopt various structures, such as a completely bent elastic plate in the second direction or a plurality of bent elastic plates arranged at intervals in the second direction.

[0051] like Figure 1 、 Figure 2As shown, further, the bending portion 210 of this embodiment includes a bending plate 211, which is connected to the second end of the shell 100 and forms a U-shaped groove, with the opening of the U-shaped groove facing the open side of the accommodating inner cavity 110. By adopting the U-shaped bending plate 211 for connection, a stable elastic force can be generated, and the width between the U-shaped grooves (the inner wall spacing in the first direction) provides a moving position for the movement of the supporting platform 220, so that the supporting platform 220 has stable movement and reset functions. The width of the opening of the U-shaped groove of this embodiment is greater than the width of the bottom of the U-shaped groove, and the width of the opening above the U-shaped groove is greater than the width of the bottom of the groove below, so that the upper end of the bending portion 210 can produce a larger deformation, thereby increasing the moving distance of the supporting platform 220 and making the elastic performance of the bending plate 211 better.

[0052] like Figure 2 、 Figure 3 As shown, in this embodiment, there are two elastic members 200, which are spaced apart along the second direction. Therefore, two second limiting members 400 are correspondingly provided in the second direction. Correspondingly, there are also two avoidance holes 120, which are located on both sides of the watchband receiving groove 111 in the second direction. In this way, when the protective film 20 is connected and limited, it will not be interfered with by the watchband receiving groove 111. In addition, the elastic members 200 on both sides of the second direction apply elastic force to the protective film 20, so that the protective film 20 can be stably stretched.

[0053] like Figure 1 、 Figure 2 、 Figure 3 As shown, further, in this embodiment, a top platform 130 is provided at the first end of the shell 100, and a first limiting member 300 is provided on the top platform 130; the top platform 130 is provided at the rear end of the shell 100, and the upper surface of the top platform 130 is flush with the upper surface of the supporting platform 220 and is higher than the upper surface of the shell 100, so that when the first limiting member 300 and the second limiting member 400 are connected to the protective film 20, the protective film 20 can be propped up in the height direction to form a dust removal space. A tear opening 140 is formed between the upper surface of the top platform 130 and the shell 100, and the tear opening 140 is used to pull out the tear release layer 23 of the protective film 20. The tear release layer 23 of the protective film 20 passes through the tear opening 140, making it convenient for the user to pull the tear release layer 23 out of the tear opening 140.

[0054] In this embodiment, two top platforms 130 are provided, spaced apart along the second direction. The tear opening 140 is formed between the two top platforms 130, and two first stoppers 300 are provided correspondingly. The two top platforms 130 are also located on either side of the strap receiving groove 111 in the second direction. This prevents interference with the strap receiving groove 111 during the connection and position control of the protective film 20. Furthermore, the protection film 20 is stably stretched by being held in position on both sides in the second direction.

[0055] like Figure 2 、 Figure 3 、 Figure 4 As shown, further, the first stopper 300 of this embodiment includes a first hook 310 or a first hanging post. The two first hooks 310 in the second direction are respectively used to connect to the first end positioning holes of the positioning release layer 21 of the protective film 20. The second stopper 400 specifically includes a second hook 410. The two second hooks 410 in the second direction are spaced apart along the second direction of the elastic member 200, and the two second hooks 410 are respectively used to connect to the second end positioning holes of the positioning release layer 21 of the protective film 20. After the positioning release layer 21 of the protective film 20 is connected to the first hook 310, the two first hooks 310 in the second direction and the two second hooks 410 in the second direction at the other end are used to connect the two ends of the protective film 20 in the first direction, so that the protective film 20 is positioned above the support limit portion. This allows the entire protective film 20 to be positioned above the screen of the smart watch 10. The tear-off film layer 22 extends through the tear-off opening 140 at the rear end, making it easier for the user to hold it. During the process of tearing the tear-off layer 23 of the protective film 20 from the film layer 22, the tear-off layer 23 will contact the screen of the smart watch 10 during the tearing process, thereby removing dust from the screen of the smart watch 10. The detached tear-off layer 23 moves out of the tear-off opening 140, exposing the film layer 22 on the protective film 20 and aligning it with the screen of the smart watch 10 below.

[0056] In addition, to achieve foolproof function, the sizes of the two second hooks 410 in the second direction can be set to different, and the sizes of the corresponding second end positioning holes of the positioning release layer 21 can also be set to different. In this way, the user can directly connect them when using them, and it is not easy to stick them upside down.

[0057] like Figure 4 、 Figure 5 、 Figure 6As shown, the dust removal film applicator of this embodiment further includes an extrusion member 500, which is movably disposed on the housing 100. The extrusion member 500 is pushed to squeeze the protective film 20 connected to the first stopper 300 and the second stopper 400. The extrusion member 500 can be a scraper 530 or a rolling wheel. By squeezing the protective film 20 with the extrusion member 500, the force applied during the film application process is stabilized. For example, by squeezing from front to back with the extrusion member 500, the generation of bubbles can be effectively avoided.

[0058] like Figure 6 As shown, further, in the first structure, the extruding member 500 may be a scraper 530. The protective film 20 is directly pressed down by the scraper 530 to achieve the film sticking function.

[0059] like Figure 3 、 Figure 4 、 Figure 5 As shown, in this embodiment, a guide rail 150 is provided on the side of the housing 100 in the second direction. The guide rail 150 extends in the first direction, and the extrusion member 500 can move from front to back along the guide rail 150. The extrusion member 500 specifically includes a sliding frame 510 and an extrusion portion 520. The sliding frame 510 is detachably connected to the housing 100 and slides along the guide rail 150 in the first direction. The extrusion portion 520 is connected to the sliding frame 510. The cooperation between the guide rail 150 and the sliding frame 510 allows stable movement in the first direction, ensuring a stable force during the extrusion process.

[0060] like Figure 3 、 Figure 4 、 Figure 5 As shown, in the second structure, the extrusion unit 520 includes a rolling roller 521, which is rotatably connected to the sliding frame 510. The rotation of the rolling roller 521 creates a rolling pattern. The rolling roller 521 can be a rubber roller, a foam roller, or the like, making it suitable for both soft and hard films. Furthermore, the rolling roller 521 can have a curved profile, allowing for extrusion of curved screens.

[0061] In the third form, the extrusion unit includes an extrusion block fixedly connected to the sliding frame. This creates a push-to-displacement mechanism. The extrusion block can be made of a rubber strip, foam strip, or other material, making it suitable for both soft and hard films. Furthermore, the extrusion block can have a curved profile, making it suitable for extruding curved screens.

[0062] like Figure 1 、 Figure 2 、 Figure 4As shown, further, the side of the housing 100 of this embodiment is provided with a turning groove 170, which can be located at the end of the guide rail 150. The turning groove 170 forms a sliding outlet 172 at one end in the first direction and is closed at the other end to form a turning position 171. The turning groove 170 is also provided with an inlet and outlet 173 opening upward, and the inlet and outlet 173 can be an opening formed by the guide rail 150 and the outer wall of the turning groove 170. In the specific structure, the sliding outlet 172 is provided toward the guide rail 150, so when the sliding frame 510 slides to the end on the guide rail 150, it can slide into the turning groove 170 to turn over. In this way, after the film is applied, the entire extrusion piece 500 (rolling structure) does not need to be removed when removing the smart watch 10; and before connecting the protective film 20, the space above the housing 100 can be made free by turning it over, making it easier to connect the protective film 20 to the housing 100.

[0063] like Figure 1 、 Figure 2 、 Figure 4 As shown, in the specific structure, the sliding frame 510 includes: two guide columns 511 are arranged on the inner wall along the first direction, and a limiting matching surface 512 is spaced a predetermined distance away from the guide columns 511. A guide matching position is formed between the guide columns 511 and the limiting matching surface 512, and the guide matching position is matched with the shell 100 to enable the sliding frame 510 to slide in a direction on the shell 100. During the sliding process, the two guide posts 511 are located below the guide rail 150 and abut against it. The sliding exit 172 of the flipping groove 170 is also located below the guide rail 150. Therefore, after the guide posts 511 slide along the guide rail 150 to the end, they can enter the flipping groove 170. When the sliding frame 510 moves into the flipping groove 170, one of the guide posts 511 located on the flipping latch 171 acts as a rotation axis, causing the other guide post 511 to rotate out of the exit 173, thereby flipping the sliding frame 510 from the top of the housing 100 to the side of the housing 100. This realizes the flipping function. This eliminates the need to install or remove the extrusion member 500 (rolling structure) from the housing 100, making it more convenient for users to apply the film.

[0064] like Figure 4 As shown, in this embodiment, a flexible pad 180 is provided on the side of the housing 100. The flexible pad 180 can be made of EVA cotton. The sliding frame 510, which is flipped from the top to the side of the housing 100, rests on the flexible pad 180, providing a cushion for the sliding frame 510 and preventing the flexible rolling roller 521 on the sliding frame 510 from colliding with the housing 100 and causing damage.

[0065] Example 2

[0066] like Figure 2 、 Figure 3 、 Figure 4 As shown, this embodiment provides a film-applying kit, including the dust-removing film applicator with elastic stretchable parts 200 and the protective film 20 as described above. Figure 3 As shown, the protective film 20 includes a film layer 22, a positioning release layer 21, and a tear-off release layer 23. The positioning release layer 21 is connected to the first stopper 300 and the second stopper 400. The tear-off release layer 23 is pulled out through the tear opening 140 to align the film layer 22 with the screen of the smartwatch 10. The film layer 22 is attached to the surface of the smartwatch 10 to protect the screen.

[0067] The release layer 21 is detachably attached to one side of the film layer 22. A first positioning hole 21a is provided at the rear end of the release layer 21 in the first direction, and a second positioning hole 21b is provided at the front end. The first and second positioning holes 21a and 21b respectively fit over the first and second hooks 310 and 410 for positioning. A tear-off release layer 23 is attached to the side of the film layer 22 facing away from the release layer 21 and toward the smartwatch 10.

[0068] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
