The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-3 The image shown is an embodiment provided by this utility model.

[0030] This utility model embodiment provides a press protection device for a spray can, including: a connecting cap 10, a handle 20, and a trigger lever 30. The connecting cap 10 has an internal hollow structure and is used to connect and seal with the top of the spray can. The lower end of the connecting cap 10 usually covers the metal edging of the upper part of the spray can, protecting the splice of the spray can. The handle 20 is C-shaped and internally hollow. The upper front end of the handle 20 is connected to and communicates with the connecting cap 10. The trigger lever 30 is hinged to the handle 20. The connection method and cooperation between the trigger lever 30 and the handle 20 can be referred to as the trigger and grip of a common toy gun. The front end of the trigger lever 30 extends into the connecting cap 10. Pulling the rear end of the trigger lever 30 can drive the front end of the trigger lever 30 to press down on the spray button of the spray can. The trigger lever 30 forms a force-saving lever, which can press the spray button more effortlessly, allowing the operator to press the spray more easily. Furthermore, a protective plate 40 extends downward from the lower edge of the connecting cap 10. The rear side wall of the protective plate 40 connects to the lower end of the handle 20. The protective plate 40 is positioned between the handle 20 and the spray can body, isolating the operator's hand from the spray can body and thus providing protection. With the aforementioned press protection device for the spray can, the connecting cap 10 can be closed onto the spray can, shielding the can opening and providing some protection against accidents such as the can opening exploding. Simultaneously, the protective plate 40 positioned between the handle 20 and the spray can body blocks and shields the spray can body from the user's hands and body, thus mitigating or reducing the injury caused by a spray can explosion.

[0031] Furthermore, the protective plate 40 and the connecting cap 10 are integrally formed, which makes the structure stronger and the impact resistance stronger. The cross-section of the protective plate 40 is arc-shaped, that is, the protective plate 40 itself is arched. Compared with a plane, the arch has higher structural strength. The angle of the arc is 120°-240°, which can cover one-third to two-thirds of the circumference of the spray can, providing a wider protective area.

[0032] Specifically, a connecting ring 11 is provided inside the connecting cap 10. The connecting ring 11 is used to engage with the edge of the spray can opening, thereby connecting and fixing the connecting cap 10 to the spray can.

[0033] Furthermore, the inner wall of the connecting cap 10 is provided with a guide post 12 and a spring 13, and the inner end of the connecting ring 11 is provided with several guide cylinders 14. The guide post 12 and the spring 13 are respectively inserted into the several guide cylinders 14. The side wall of the connecting cap 10 is provided with an opening for the connecting ring 11 to be inserted. The connecting ring 11 slides inward to retract the spring 13. When the spring 13 is in the fully retracted state, the center of the connecting ring 11 coincides with the axis of the connecting cap 10. At this time, the size of the ring opening of the connecting ring 11 is just enough to accommodate the edge of the spray can. The spray can can be freely inserted into or removed from the connecting cap 10. When the spring 13 rebounds, the connecting ring 11 slides outward, and its ring opening is blocked and becomes smaller. At this time, the connecting ring 11 can clamp and fix the mouth of the spray can. By pressing and moving the connecting ring 11, the connecting cap 10 and the spray can can be easily disassembled and assembled, making it more convenient to use.

[0034] Specifically, a spray nozzle 15 is provided on the front side wall of the connecting cap 10. The spray nozzle 15 is used to avoid the nozzle of the spray can, so as to facilitate the spraying out.

[0035] Specifically, the trigger lever 30 is shaped like a "7". The front half of the trigger lever 30 is provided with a hinge hole 31 near the corner. The handle 20 is provided with a hinge shaft 21. The hinge hole 31 is hinged to the hinge shaft 21, so that the lever arm of the rear section of the trigger lever 30 at the hinge is longer than that of the front section, thus forming a force-saving lever.

[0036] Furthermore, an elastic arm 32 is provided on the outer side of the corner of the trigger lever 30. The rear end of the elastic arm 32 extends obliquely upward and abuts against the inner top wall of the grip 20. The elastic arm 32 is used to make the trigger lever 30 spring back to its original position. When the trigger lever 30 is pulled backward, the elastic arm 32 undergoes elastic deformation. When the trigger lever 30 is released, the elastic potential energy of the elastic arm 32 will drive the lower end of the trigger lever 30 to return to its original position.

[0037] Specifically, the front end of the trigger lever 30 is provided with a pressing head 33, which is used to abut against the top of the spray button.

[0038] Furthermore, a raised edge 34 is provided on the inner edge of the trigger lever 30. The width of the raised edge 34 is greater than the thickness of the trigger lever 30, which can increase the contact area between the user's fingertip and the trigger lever 30, so that it will not be uncomfortable when pulling the trigger lever 30, making it more comfortable.

[0039] Furthermore, both the connecting cap 10 and the handle 20 can be split in half, which facilitates the production, processing, and disassembly of the pressing device.

[0040] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
