A foaming instrument

Abstract

This invention relates to a foam tool, which comprises a casing body, a connecting element, a liquid inlet valve, a liquid outlet valve, and a switch device. The switch device can lead the liquid outlet valve to be opened or closed. The invention is characterized in that the liquid inlet valve and the casing body and / or the connecting element are made into a split structure; the foam tool also comprises a sealing device arranged between the liquid inlet valve and the connecting element or the casing body, parts easy to be damaged or to leak or to be blocked in the foam tool can be converted conveniently, in particular the liquid inlet valve can be converted, the troubles easy to appear in the foam tool are solved, the resource is greatly saved, the structure is simple, the installation is convenient, and the foam tool is suitable for mass production.

Description

technical field [0001] The invention relates to a foam tool for spraying foam filler. Background technique [0002] Foam fillers are generally used for the anti-seepage installation or gap filling of doors and windows in houses, the insulation of air-conditioning installations, leak-proof layers, the filling of remaining holes in various pipeline installations, switch sockets and related installations that require insulation, etc. When using raw materials, the foam filler is quantitatively released through the foaming tool to achieve the purposes of installation, caulking, leak repair, heat preservation, insulation or bonding. The foam filler is generally filled with air pressure in the cavity of the foaming tool. In liquid state, when the liquid nozzle is opened by the switch device in the foaming tool, the sprayed foam filler is solidified and adhered to the desired place. However, this highly viscous foam filler passes through the foaming tool. The liquid inlet valve has...

[0002] Foam fillers are generally used for the anti-seepage installation or gap filling of doors and windows in houses, the insulation of air-conditioning installations, leak-proof layers, the filling of remaining holes in various pipeline installations, switch sockets and related installations that require insulation, etc. When using raw materials, the foam filler is quantitatively released through the foaming tool to achieve the purposes of installation, caulking, leak repair, heat preservation, insulation or bonding. The foam filler is generally filled with air pressure in the cavity of the foaming tool. In liquid state, when the liquid nozzle is opened by the switch device in the foaming tool, the sprayed foam filler is solidified and adhered to the desired place. However, this highly viscous foam filler passes through the foaming tool. The liquid inlet valve has the following disadvantages; ①After the foaming tool is used for a period of time, the liquid inlet valve is very easy to accumulate solidified foam filler, causing the foaming tool to be scrapped due to leakage or blockage

②If the sealing degree of the liquid inlet valve is not up to the standard or there is a slight leakage, the foam filler in the foaming tool is easy to leak or solidify, which shortens the service life

③Because the liquid inlet valve can be docked many times with the external tank containing the foam filler, so that the foam filler enters the inner channel of the foaming tool through the liquid inlet valve, when they are connected or When exiting, the foam filler with high air pressure is easy to leak sideways instantly or the residual foam filler overflows, causing residue on the inlet valve, thus destroying the sealing performance of the filling body and the inlet valve. It is easy to cause liquid leakage and cause the entire foaming tool to be blocked

Therefore, the foaming tools on the existing market are extremely easy to leak or block or damage, resulting in a huge consumption of foaming tools and a waste of resources
