How to make it easier to press down on the spray switch has become a technical problem that those skilled in the art urgently need to solve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pressing component and an aerosol sprayer. The aerosol sprayer using the pressing component is easy and labor-saving when pressing and spraying.

[0004] To solve the above-mentioned technical problems, this utility model provides a pressing assembly, including an annular seat. A spray nozzle is provided on the front side wall of the annular seat, and a groove is provided on the top rear side of the annular seat. A safety cover and a swing block are movably connected to the top front side of the annular seat. The safety cover is located above the swing block. A pressing protrusion is provided on the bottom surface of the swing block, and a mounting cavity is provided on the rear end surface of the swing block. A slider is slidably fitted within the mounting cavity. A limiting structure is provided between the slider and the mounting cavity to prevent the slider from sliding out of the mounting cavity. A pressing part is provided at the tail end of the slider, and the pressing part is fastened to the safety cover. The pressing part rests on the inner bottom surface of the groove. In use, the pressing part is unfastened from the safety cover, and then the pressing part is pulled backward from the groove, allowing downward pressing.

[0005] In a further preferred embodiment, an elastic element is provided between the inner end face of the mounting cavity and the slider; when the pressing part is disengaged from the safety cover, the elastic element drives the slider to slide backward, thereby causing the pressing part to pop out backward from the groove; thus, there is no need to manually pull the pressing part out backward from the groove, improving the ease of use.

[0006] In a further preferred embodiment, the limiting structure includes a pair of limiting rods, which are symmetrically arranged on the left and right inner walls of the mounting cavity. The outer surface of the slider is provided with a groove that is the same number and position as the limiting rods. The limiting rods slide in the grooves. When the pressing part is pulled out backward from the groove, the pressing part cannot continue to move backward when the limiting rod abuts against the front inner wall of the groove, and the slider will not slide out of the mounting cavity.

[0007] In a further preferred embodiment, a pin is provided between the left and right side walls of the front part of the annular seat, located above the injection port, and the safety cover and the swing block are respectively movably connected to the pin.

[0008] In a further preferred embodiment, the left and right sides of the tail end of the safety cover are respectively provided with downwardly extending protrusions, and the top of the pressing part is provided with a fastening groove that is the same number and position as the protrusions. The protrusions are fastened in the fastening grooves. When the protrusions are fastened in the fastening grooves, the pressing part cannot be pulled out of the grooves backward. By flipping the safety cover up, the protrusions are dislodged from the fastening grooves, and at this time the pressing part can be pulled out of the grooves backward.

[0009] In a further preferred embodiment, a return spring is provided between the pin and the safety cover. The return spring is a torsion spring, which ensures that the safety cover always tends to flip downwards. The rear side of the protrusion is arc-shaped. After pressing the pressing part, the pressing part is pushed forward so that it abuts against the rear side of the protrusion, forcing the safety cover to flip upwards and the protrusion to slide above the pressing part. The pressing part is then pushed forward again so that the protrusion engages in the engaging groove. This achieves self-locking between the safety cover and the pressing part, improving ease of use.

[0010] An aerosol sprayer includes the aforementioned pressing assembly and a sprayer body. An annular seat is disposed on the top of the sprayer body, and a spray switch of the sprayer body is located within the annular seat. When the pressing part is pressed down, the pressing protrusion abuts against the spray switch.

[0011] In a further preferred embodiment, the injector body includes a container, the annular seat is disposed on the top of the container, and the outer side and bottom surface of the container are covered with a silicone layer; when the user holds the injector body, the hand comes into contact with the silicone layer, resulting in a better tactile experience.

[0012] The beneficial effects of this utility model are as follows: The pressing component includes a locked state and an unlocked state. The pressing part is fastened to the safety cover, and the pressing part is supported on the inner bottom surface of the groove. At this time, the pressing component is in the locked state, and the pressing part cannot be pulled out of the groove backward, nor can it be pressed downward. First, the fastening connection between the pressing part and the safety cover is released, and then the pressing part is pulled out of the groove backward. Then, the pressing part can be pressed downward. At this time, the pressing component is in the unlocked state. When pressing the pressing part downward with a finger, the pressing protrusion applies pressing force to the target object. Since the pressing part is pulled backward a certain distance when unlocking the pressing component, the length of the power arm is increased. According to the lever principle of saving effort, increasing the length of the power arm can reduce the required finger pressing force. The aerosol sprayer using this new pressing component has the characteristics of being easy and effortless when pressing and spraying. Attached Figure Description
