Description

Technical Field

[0001] This utility model relates to the field of teaching stationery technology, specifically to a spray-on eraser. Background Technology

[0002] In teaching or meetings, it is often necessary to record some content on a whiteboard. However, the writing on the whiteboard tends to solidify on the surface after a period of time. To remove solidified ink stains from the whiteboard, a spray eraser with a built-in spray bottle has been developed. When it is necessary to wipe the solidified ink stains on the whiteboard surface, pressing the spray bottle wets the solidified ink stains, achieving a better erasing effect.

[0003] Chinese utility model patent CN217022011U discloses a spray-on wiper, the structure of which is as follows: Figure 1 and Figure 2 As shown, the device includes a connecting housing, a wiping plate 1a, and a spray bottle 2a. The spray bottle 2a has a nozzle 3a with a button 4a. The connecting housing includes a detachably connected first housing 5a and second housing 6a. The first housing 5a has a notch 7a, a snap-fit ​​protrusion 8a, and a snap-fit ​​groove 9a on the snap-fit ​​protrusion 8a. The second housing 6a has a snap-fit ​​recess 10a and a snap-fit ​​block 11a on the snap-fit ​​recess 10a. When installing the connecting housing, the first housing 5a and second housing 6a are closed, so that the snap-fit ​​protrusion 8a is inserted into the snap-fit ​​recess 10a and the snap-fit ​​block 11a is inserted into the snap-fit ​​groove 9a. When disassembling the connecting housing, tools or fingers are used to pry open the first housing 5a and second housing 6a by inserting into the notch 7a, thereby disengaging the snap-fit ​​block 11a from the snap-fit ​​groove 9a.

[0004] However, the existing spray wiper has the following technical problems: When it is necessary to disassemble the connecting housing to replenish the liquid in the spray bottle 2a, the first housing 5a and the second housing 6a are forcibly pried open by the slot 7a to separate the snap block 11a from the snap groove 9a. This is difficult to remove and can easily damage the product. In addition, the snap-fit ​​connection structure between the snap block 11a and the snap groove 9a is located on the left and right sides of the first housing 5a and the second housing 6a, while the slot 7a is located on the rear side of the first housing 5a and the second housing 6a. That is, the slot 7a and the snap-fit ​​connection structure are not in the same position, which causes the force acting in the slot 7a to not directly act on the snap-fit ​​connection structure, further increasing the difficulty of removal. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a spray plate wipe that is easy to remove and does not easily damage the product.

[0006] The technical solution of this utility model is: a spray wiper, comprising a housing and a spray bottle installed inside the housing; the housing includes an upper cover and a base connected to each other, and a notch is provided on one side of the upper cover or the base; the upper cover and the base are provided with a quick-release structure on the side with the notch, the quick-release structure including...

[0007] An elastic buckle has one end fixed to the base and the other end being a free end. The free end of the elastic buckle extends into the slot and a snap-fit ​​groove is provided at that end.

[0008] The hook has one end fixed inside the upper cover and the other end provided with a hook, which can be connected to the snap-fit ​​groove of the elastic buckle.

[0009] When the top cover is placed on the base, the hook of the hook engages in the slot of the elastic buckle; when the elastic buckle in the slot is pressed, the hook of the hook disengages from the slot of the elastic buckle, thereby separating the top cover from the base.

[0010] With the above structure, this utility model has the following advantages:

[0011] This utility model spray wipe connects the top cover and the base together using elastic buckles and hooks. Because the elastic buckles are elastic, the separation of the elastic buckles and hooks is not a hard separation, but a non-destructive separation achieved by pressing the elastic buckles to misalign the locking groove and the hook. Therefore, it is easy to remove and does not easily damage the product. In addition, since the free end of the elastic buckle is located in the locking groove, the force applied to the locking groove can be directly applied to the elastic buckle, further facilitating removal.

[0012] Preferably, the top cover and the base are hinged or detachably connected via a snap-fit ​​or plug-in structure on opposite sides of the quick-release structure. This arrangement allows the other side of the top cover to also separate from the base, making it easier to remove the spray bottle.

[0013] Preferably, the plug-in structure includes a limiting block protruding from the plug-in side of the upper cover and a limiting groove disposed on the plug-in side of the base. The limiting groove has a limiting step. When the upper cover is closed on the base, the limiting block is limited within the limiting groove, and the top of the limiting block abuts against the limiting step. The plug-in structure facilitates installation and is simple, effectively limiting both the left-right movement of the upper cover using the limiting groove and the up-down movement using the limiting step.

[0014] Preferably, the upper cover is provided with a plurality of first limiting ribs spaced apart between the plug-in structure and the quick-release structure. The base is provided with second limiting ribs that cooperate with the first limiting ribs. The first limiting ribs and the second limiting ribs are staggered in sequence. When the upper cover is closed on the base, the first limiting ribs of the upper cover abut against one side of the second limiting ribs of the base. This arrangement, together with the quick-release structure, further restricts the back-and-forth movement of the upper cover, and the first limiting ribs and the second limiting ribs are also connected by a plug-in connection, making disassembly and assembly very convenient.

[0015] Preferably, the plug-in structure and the quick-release structure are respectively disposed on the front and rear sides of the upper cover. The first limiting rib is U-shaped and extends from the left side to the right side of the upper cover. The second limiting rib is provided on both the left and right sides of the base. When the upper cover is closed on the base, the two ends of the first limiting rib abut against the same side of the second limiting rib on the left and right sides of the base. The provision of the first and second limiting ribs on both the left and right sides makes the front and rear positioning of the upper cover and the base more reliable.

[0016] Preferably, a clamping channel for the spray bottle is formed between the first limiting rib and the second limiting rib, and the width of the clamping channel matches the width of the spray bottle body. This arrangement enables the functional reuse of the first and second limiting ribs, eliminating the need for an additional clamping structure for the spray bottle, resulting in a simpler and more compact overall structure.

[0017] Preferably, the top cover also has an opening slot on the side opposite to the slotted area, and a push button is slidably connected within the opening slot. The push button is linked to the nozzle of the spray bottle. This design allows for convenient operation of the nozzle by pressing an external push button.

[0018] Preferably, the opening groove has a horizontal first guide surface, and the push button has a first guide portion along the sliding direction. The first guide portion has an upper sliding surface and a lower sliding surface, and the upper sliding surface and / or the lower sliding surface also has a guide ridge. When the push button is pushed, the first guide surface slides between the upper sliding surface and the lower sliding surface and makes line contact with the upper sliding surface and / or the lower sliding surface through the guide ridge. This arrangement can use the first guide portion and the first guide surface to guide the pushing direction of the push button, thereby ensuring that the push button can reliably press the nozzle of the spray bottle to spray out cleaning liquid. In addition, the guide ridge on the upper sliding surface and / or the lower sliding surface that makes line contact with the first guide surface can reduce friction during the pushing process of the push button, making the sliding of the push button smoother.

[0019] Preferably, a second guide portion is provided within the opening groove along the sliding direction of the push button, and the push button has a vertical second guide surface; when the push button is pushed, the second guide surface slides relative to the second guide portion. This arrangement utilizes the second guide surface and the second guide portion to guide the pushing direction of the push button, thereby ensuring that the push button can reliably press the nozzle of the spray bottle to spray out cleaning liquid.

[0020] Preferably, guide sliders are provided on both sides of the push button, and a guide seat extending along the sliding direction of the push button is provided inside the base and below the guide sliders; when the push button is pushed, the guide sliders slide on the guide seat. This arrangement can guide the pushing direction of the push button using the guide sliders and the guide seat, thereby ensuring that the push button can reliably press the nozzle of the spray bottle to spray out cleaning liquid.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] Example:

[0034] like Figure 3-9 As shown, a spray wiper includes a housing 1 and a spray bottle 2 installed inside the housing 1. The housing 1 includes an upper cover 3 and a base 4 connected to each other. A slot 5 is provided on one side of the upper cover 3 or the base 4. In this embodiment, the slot 5 is provided on the upper cover 3, and the upper cover 3 and the base 4 are provided with a quick-release structure 6 on the side where the slot 5 is provided. The quick-release structure 6 includes...

[0035] The elastic buckle 7 has one end fixed to the base 4 and the other end is a free end. The free end of the elastic buckle 7 extends into the slot 5 and a snap-fit ​​groove 8 is provided at the end. In this embodiment, the elastic buckle 7 includes a vertical part 28 and a horizontal part 29 provided on one side of the vertical part 28. The horizontal part 29 is located below the top of the vertical part 28. The vertical part 28 and the horizontal part 29 are connected by an arc part 30. The snap-fit ​​groove 8 is provided on the horizontal part 29.

[0036] The hook 9 has one end fixed inside the upper cover 3 and the other end is provided with a hook part 10. The hook part 10 can be connected to the snap-fit ​​groove 8 of the elastic buckle 7. The width D1 of the snap-fit ​​groove 8 is greater than the width D2 of the hook part 10.

[0037] When the top cover 3 is placed on the base 4, the hook 10 of the hook 9 is engaged in the slot 8 of the elastic buckle 7; when the elastic buckle 7 in the slot 5 is pressed, the hook 10 of the hook 9 disengages from the slot 8 of the elastic buckle 7, thereby separating the top cover 3 from the base 4. In this embodiment, the pressing direction of the elastic buckle 7 is consistent with the width D1 direction of the slot 8.

[0038] In this embodiment, the spray plate wiper connects the upper cover 3 and the base 4 together through the elastic buckle 7 and the hook 9. Because the elastic buckle 7 is elastic, the separation of the elastic buckle 7 and the hook 9 is not a hard separation, but a non-destructive separation that can be achieved by pressing the elastic buckle 7 to misalign the locking groove 8 and the hook part 10. Therefore, it is easy to remove and does not easily damage the product. In addition, since the free end of the elastic buckle 7 is located in the groove 5, the force applied to the groove 5 can be directly applied to the elastic buckle 7, further facilitating removal.

[0039] The top cover 3 and the base 4 are hinged on opposite sides of the quick-release structure 6 or detachably connected via a snap-fit ​​or plug-in structure. This arrangement allows the other side of the top cover 3 to also separate from the base 4, making it easier to remove the spray bottle 2.

[0040] The plug-in structure includes a limiting block 11 protruding from the plug-in side of the upper cover 3 and a limiting groove 12 disposed on the plug-in side of the base 4. A limiting step 13 is provided within the limiting groove 12. When the upper cover 3 is closed onto the base 4, the limiting block 11 is limited within the limiting groove 12, and the top of the limiting block 11 abuts against the limiting step 13. In this embodiment, the limiting block 11 is L-shaped. The plug-in structure facilitates installation and is simple, effectively limiting the left-right movement of the upper cover 3 using the limiting groove 12 and the up-down movement of the upper cover 3 using the limiting step 13.

[0041] Inside the upper cover 3, and between the plug-in structure and the quick-release structure 6, several first limiting ribs 14 are provided at intervals. The base 4 has second limiting ribs 15 that cooperate with the first limiting ribs 14. Each first limiting rib 14 and each second limiting rib 15 are staggered sequentially. When the upper cover 3 is closed on the base 4, the first limiting ribs 14 of the upper cover 3 abut against one side of the second limiting ribs 15 of the base 4. In this embodiment, the first limiting ribs 14 abut against the front side of the second limiting ribs 15. This arrangement, in conjunction with the quick-release structure 6, further restricts the forward and backward movement of the upper cover 3. Furthermore, the first limiting ribs 14 and the second limiting ribs 15 are connected by a plug-in connection, making disassembly and assembly very convenient.

[0042] The plug-in structure and quick-release structure 6 are respectively set on the front and rear sides of the upper cover 3. The first limiting rib 14 is U-shaped and extends from the left side to the right side of the upper cover 3. The left and right sides of the base 4 are provided with second limiting ribs 15. When the upper cover 3 is closed on the base 4, the two ends of the first limiting rib 14 abut against the same side of the second limiting ribs 15 on the left and right sides of the base 4. In this embodiment, the upper, lower, left, right, front, and rear are defined as follows: Figure 3 For reference. First limiting ribs 14 and second limiting ribs 15 are provided on both the left and right sides to make the front and rear limiting of the upper cover 3 and the base 4 more reliable.

[0043] A clamping channel 16 for the spray bottle 2 is also formed between the first limiting rib 14 and the second limiting rib 15, and the width of the clamping channel 16 matches the width of the spray bottle 2. This setting realizes the functional reuse of the first limiting rib 14 and the second limiting rib 15, eliminating the need for an additional clamping structure for the spray bottle 2, and making the overall structure simpler and more compact.

[0044] An opening slot 17 is provided on the upper cover 3, opposite to the slot 5. A push button 18 is slidably connected within the opening slot 17, and the push button 18 is linked to the nozzle 34 of the spray bottle 2. In this embodiment, the slot 5 is located on the rear side of the upper cover 3, the opening slot 17 is located on the front side of the upper cover 3, and the push button 18 is slidably connected within the opening slot 17. Two plug-in structures are provided and symmetrically arranged on the left and right sides of the push button 18. This arrangement facilitates pressing the nozzle 34 using the external push button 18, making it more convenient to use.

[0045] The opening groove 17 is provided with a horizontal first guide surface 19, and the push button 18 is provided with a first guide part 20 along the sliding direction. The first guide part 20 has an upper sliding surface 21 and a lower sliding surface 22, and the upper sliding surface 21 and / or the lower sliding surface 22 are also provided with guide protrusions 23. When the push button 18 is pushed, the first guide surface 19 slides between the upper sliding surface 21 and the lower sliding surface 22 and makes line contact with the upper sliding surface 21 and / or the lower sliding surface 22 through the guide protrusions 23. In this embodiment, the first guide part 20 is closed on the front side and open on the rear side. It is surrounded by the upper sliding surface 21, the lower sliding surface 22 and the front side to form a U-shaped guide groove. Two guide protrusions 23 are provided and are arranged side by side on the upper sliding surface 21. This configuration utilizes the first guide portion 20 and the first guide surface 19 to guide the pushing direction of the push button 18, thereby ensuring that the push button 18 can reliably press the nozzle 34 of the spray bottle 2 to spray out cleaning liquid; in addition, the upper sliding surface 21 and / or the lower sliding surface 22 are provided with guide protrusions 23 that are in line contact with the first guide surface 19, which can reduce the friction during the pushing process of the push button 18 and make the sliding of the push button 18 smoother.

[0046] A second guide portion 24 is provided inside the opening groove 17 along the sliding direction of the push button 18, and the push button 18 is provided with a vertical second guide surface 25; when the push button 18 is pushed, the second guide surface 25 slides relative to the second guide portion 24; in this embodiment, the second guide portion 24 is opened on the first guide surface 19 and opens inward from the front side of the first guide surface 19. The second guide portion 24 is a through groove with a U-shaped cross-section, which is open from top to bottom and closed from the front side. The second guide surface 25 connects the middle part of the upper sliding surface 21 and the middle part of the lower sliding surface 22. This arrangement can use the second guide surface 25 and the second guide portion 24 to guide the pushing direction of the push button 18, thereby ensuring that the push button 18 can reliably press the nozzle 34 of the spray bottle 2 to spray out cleaning liquid.

[0047] Guide sliders 26 are provided on both sides of the push button 18. A guide seat 27 extending along the sliding direction of the push button 18 is provided inside the base 4 and below the guide sliders 26. When the push button 18 is pushed, the guide sliders 26 slide on the guide seat 27. In this embodiment, a limiting part 31 is provided below the first guide part 20 of the push button 18. The nozzle 34 of the spray bottle 2 is installed in the limiting part 31. The guide sliders 26 are located on the left and right sides of the limiting part 31. The limiting part 31 can be implemented using existing technology. This arrangement uses the guide sliders 26 and the guide seat 27 to guide the pushing direction of the push button 18, thereby ensuring that the push button 18 can reliably press the nozzle 34 of the spray bottle 2 to spray out cleaning liquid.

[0048] The front side of the base 4 has a curved surface 32 that gradually tapers inward from top to bottom. The wiping cloth 33 extends from the bottom of the base 4 to the front side, and the installation of the wiping cloth 33 can be achieved using existing technology. This design allows the entire unit to stand upright during use, utilizing the curved surface 32, thus facilitating the wiping of small, localized areas.

[0049] The disassembly and assembly process of the spray-on wiper in this embodiment is as follows:

[0050] Installation process: Install the push button 18 on the base 4, then install the nozzle 34 of the spray bottle 2 into the limiting part 31 of the push button 18 and install the bottle body between the second limiting ribs 15 on the left and right sides of the base 4; then align the first guide surface 19 on the front side of the top cover 3 with the first guide part 20 of the push button 18 and align the limiting block 11 with the limiting groove 12 of the base 4 and install it. After the front side of the top cover 3 is installed in place, the limiting block 11 is limited in the limiting groove 12 and abuts against the limiting step 13 of the limiting groove 12; finally, press down the rear side of the top cover 3, and the hook part 10 of the hook 9 is engaged in the locking groove 8 of the elastic buckle 7 to fix the top cover 3 and the base 4 together. At the same time, the first limiting rib 14 is inserted into the base 4 and abuts against the front side of the second limiting rib 15, further restricting the back and forth movement of the top cover 3 and the base 4. In addition, the first limiting rib 14 of the top cover 3 and the second limiting rib 15 of the base 4 also form a clamping channel 16 to fix the bottle body of the spray bottle 2.

[0051] Removal process: Press the elastic buckle 7, the hook 10 of the hook 9 disengages from the locking groove 8 of the elastic buckle 7, and the rear side of the top cover 3 separates from the rear side of the base 4. Then pull the top cover 3 out backward, and the front side of the top cover 3 can be pulled out from the push button 18. At this time, the top cover 3 is completely separated from the base 4, and the spray bottle 2 can be removed from the base 4 to add cleaning agent.
