Patent Application
20250073728
The present invention relates to the technical field of foam spraying devices, in particular to a foam pot.
A foam pot is a device that fills a prepared foam solution into the pot body and then attaches it to the high-pressure cleaning gun. By setting a foam ball on the foam pot and pressurizing it through the high-pressure cleaning machine, the foam solution flows through the foam ball to produce foam and then sprays out through the nozzle. Chinese Patent No. 213855168 discloses a foam nozzle, including a connecting joint body and a nozzle body, and an axial passage communicating with each other is provided inside the connecting joint body and the nozzle body; the nozzle body includes a front nozzle, a middle connecting passage, and a rear mixing chamber. A connecting head is provided at the front of the connecting joint body; the port of the mixing chamber at the rear of the nozzle body is screwed onto the external thread of the connecting head, and a mixing nozzle is provided at the front end of the connecting head. The outer diameter of the mixing nozzle is smaller than that of the connecting head. A first sealing ring is sleeved on the outer wall of the front end of the mixing nozzle; The first sealing ring plays a sealing effect between the mixing nozzle and the inner wall of the connecting passage; this utility model well solves the water leakage problem of existing foam pots and has good foaming effect.
However, this structure also has defects. Its foam ball is located inside the nozzle, and another end of the nozzle is connected with a clip. The clip bracket is sleeved on the outer circumference of the clip. The angle adjustment knob is also sleeved on the outer circumference of the foam inlet pipe, nozzle, clip bracket, and clip. The disadvantage of this structure is that when it is necessary to take out and replace the foam ball, it is necessary to disassemble both angle adjustment knob and nozzle; in addition, using only one nozzle increases material production for entire foam pot, increasing cost; when installing angle adjustment knob, it needs to be aligned with clip bracket for installation, which is inconvenient to operate.
Furthermore, pot lids connected to pot bodies are generally made by metal machining. To prevent corrosion, stainless steel or copper are generally used. Since these two metals are relatively expensive, this method is only suitable for small-sized pot lids or for household use. When commercial use requires large-sized foam pots, it is obviously not suitable to use metal processing to make large-sized pot lids.
Nowadays, there are also disclosures of foam pots that do not use separate nozzles. US Patent Publication No. US20200290064A1 discloses a multi-mode high-pressure foam gun in which its foam ball is set between foaming eccentric disk and air-mixing connection pipe. This multi-mode high-pressure foam gun also includes a nozzle-type turntable with vertical fan-shaped nozzles, horizontal fan-shaped nozzles, conical nozzles, down-pressing nozzles and linear nozzles on it. Therefore, it can provide multiple spraying modes but setting multiple spraying modes will increase manufacturing costs and failure rates. Not all users need multi-mode foam guns so it is necessary to design a simple structured foam pot to solve problems in existing technology.
