Description

Technical Field

[0001] This utility model belongs to the field of spray bottles, and specifically relates to a foam spray bottle. Background Technology

[0002] A spray bottle is a common and highly practical spraying tool. Its compact size, small footprint, portability, and handheld operation make it widely used in homes, offices, schools, and other locations. Spray bottles are commonly used for humidifying the air, watering plants, and spraying disinfectants and cleaning solutions. When cleaning objects (such as vehicles), the liquid sprayed from the bottle contains a certain amount of cleaning or disinfectant, which produces a certain amount of foam; in this case, the spray bottle functions as a foam sprayer.

[0003] Some existing foam sprayers use a threaded connection between the nozzle and the sprayer body, which makes disassembly and assembly cumbersome and inconvenient for cleaning, maintenance, or replacement of the nozzle. In addition, if the foaming net of some foam sprayers becomes clogged, it is either not removable or difficult to disassemble, so the entire sprayer must be replaced, which increases the cost of use. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a detachable foam sprayer.

[0005] The purpose of this utility model can be achieved through the following technical solution: A foam spray bottle includes a bottle body and a spout on the top of the bottle body. The spout is characterized by having a quick-release assembly, a T-shaped base for fitting onto the spout, a groove on the base, a stepped post at the center of the groove, a through hole penetrating the T-shaped base, a first return spring in the groove, a second return spring on the stepped post, several buckles circumferentially arranged around the edge of the T-shaped base, a reinforcing cover on the T-shaped base, a circumferentially oriented slot for buckle installation on the reinforcing cover, a through hole at the center of the reinforcing cover, several limiting ring blocks around the through hole for limiting position, several circumferentially oriented opening slots on the sidewall of the reinforcing cover, convex locking blocks on the opening slots, and a snap-fit ​​component on the reinforcing cover.

[0006] In the aforementioned foam spray bottle, the snap-fit ​​component has a snap-fit ​​ring, which is fitted onto a limiting ring block. The snap-fit ​​ring is circumferentially provided with several snap-fit ​​brackets for inserting into the opening slots, and each snap-fit ​​bracket is provided with a snap-fit ​​claw. A through hole is formed in the middle of each snap-fit ​​bracket. A guide post is provided at the center of the snap-fit ​​component, and a pressure plate for squeezing the snap-fit ​​bracket is provided on the guide post. A protective cover is fitted on the guide post. The guide post penetrates downward through the snap-fit ​​component, the reinforcing cover, and the T-shaped base, and extends upward through the protective cover and outward. A spraying assembly is connected to the guide post outside the protective cover.

[0007] In the aforementioned foam sprayer, a handwheel assembly is connected to one side of the spraying component. The handwheel assembly includes a handwheel cover and a foam seat. The spraying component is connected to the foam seat via threads. The foam seat has an annular groove. A fastener for fixing the annular groove is provided on the handwheel cover. The foam seat has two symmetrical rotating blocks. The rotating blocks have cover plates. The handwheel cover has a limiting tube that cooperates with the rotating blocks. The limiting tube has two fixing blocks for the rotating blocks to abut against.

[0008] In one of the aforementioned foam sprayers, the snap-fit ​​component is made of an elastic material.

[0009] Compared to existing technologies, this foam sprayer utilizes a return spring within the groove to provide vertical elastic support for the reinforcing cap, and a return spring on the stepped post to provide support for the snap-fit ​​component. These two elements work together to ensure the quick-release assembly automatically resets after disassembly, facilitating reuse. The snap-fit ​​component is made of elastic material, allowing the claws to flexibly lift when the pressure plate is pressed, facilitating disassembly while ensuring a tight fit after installation. The spray assembly is threadedly connected to the foam base, and the center of the spray assembly is connected to the guide post, facilitating the removal and replacement of the foam net and reducing maintenance costs.
