Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to a multi-purpose nozzle for polyurethane foam sealant. Background Technology

[0002] Polyurethane sealant is a product of the cross-fertilization of aerosol technology and polyurethane foam technology. It is a special polyurethane product that contains polyurethane prepolymer, foaming agent, catalyst and other components in a pressurized aerosol can. It can be used for sealing leaks, filling gaps, fixing and bonding, thermal insulation and sound insulation, and is especially suitable for sealing leaks and waterproofing between PVC or aluminum alloy doors and windows and walls.

[0003] Currently, the surface drying time is generally around 10 minutes (at room temperature of 20℃). The full drying time varies depending on ambient temperature and humidity. Generally, it takes about 4-6 hours to fully dry in summer, and 24 hours or longer in winter at around zero degrees Celsius. Under normal use conditions (and with an external covering), its service life is estimated to be no less than ten years. The cured foam maintains good elasticity and adhesion within a temperature range of -10℃ to 80℃. The cured foam has functions such as filling, bonding, and sealing. Furthermore, flame-retardant polyurethane sealant can achieve flame-retardant ratings of B and C.

[0004] However, with the increasing applications of expanding foam, it can no longer meet construction needs. For example, when used to bond sheet-like objects such as insulation boards, traditional glue guns can only spray a few cylindrical strips, making it impossible to cover the entire sheet-like object. The increased thickness of the cylindrical glue strips also leads to glue waste. Existing nozzles have relatively limited functions, only able to spray the object in a circumferential pattern. When spraying, the operator needs to hold their hand up, with the bottom of the sprayed surface exposed, and the glue is easily spilled onto their body, putting a great burden on the workers. After spraying, cleaning and other operations are required. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a multi-purpose spray nozzle for polyurethane foam sealant. This addresses the problem that as the applications of expanding foam adhesive increase, it can no longer meet construction needs. For example, when used to bond sheet-like objects such as insulation boards, traditional glue guns can only spray a few cylindrical strips, making it impossible to cover the entire sheet-like object. The increased thickness of the cylindrical glue strips also leads to glue waste. Existing spray nozzles have relatively limited functions, only able to spray circumferentially onto objects. During spraying, the operator needs to hold their hand up, with the bottom of the sprayed surface exposed, making it easy for glue to spill onto their body, which puts a heavy burden on the worker. Furthermore, cleaning is required after spraying.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A multi-purpose nozzle for polyurethane foam sealant includes: a glue gun body, the glue gun body comprising a threaded tube and a glue gun barrel, a storage component being provided at the top of the threaded tube, a nozzle assembly being provided at one end of the glue gun barrel, the other end of the glue gun barrel being configured as a threaded opening, the nozzle assembly comprising a mounting plate, a V-shaped nozzle, a lever, a hook-shaped nozzle, and a threaded sleeve, the V-shaped nozzle and the hook-shaped nozzle being both embedded inside the mounting plate, a nozzle being provided at one end of the V-shaped nozzle and the hook-shaped nozzle, the nozzle of the V-shaped nozzle being configured as V-shape, the nozzle of the hook-shaped nozzle being configured as √-shape, and a threaded sleeve being provided at the other end of the V-shaped nozzle and the hook-shaped nozzle, a lever being fixedly installed on one outer wall of the mounting plate, and the threaded sleeve being threadedly and movably sleeved on the outside of the threaded opening.

[0008] Furthermore, the glue gun body also includes a glue gun handle, a flow switch, a mounting bracket, a connecting tube, a push rod, and a control wrench, with the top of the glue gun handle fixedly connected to one end of the mounting bracket.

[0009] Furthermore, the other end of the mounting bracket is fixedly connected to the connecting pipe, one end of the push rod is movably inserted into the interior of the connecting pipe, and the other end of the push rod is fixedly connected to the flow switch.

[0010] Furthermore, the top of the control wrench is movably connected to the middle part of the mounting bracket via a pivot, and the control wrench is movably sleeved on the outside of the push rod.

[0011] Furthermore, the storage component includes an output head and a bottle body, the inside of which is filled with polyurethane foam sealant, and the bottom end of the bottle body is fixedly connected to the output head.

[0012] Furthermore, the output head is threaded into the top end of the threaded tube, the bottom end of the threaded tube is connected to the connecting tube, and the other end of the connecting tube is connected to the glue gun barrel.

[0013] The beneficial effects of this utility model are:

[0014] By incorporating a nozzle assembly and adding an external nozzle to the glue gun, the cylindrical glue can be compressed and sprayed out in a mist form. This allows for a thin, even layer of glue to be applied to a flat surface, significantly increasing the bonding area while also saving glue. During use, the threaded sleeves of the V-shaped and hook-shaped nozzles are movably fitted onto one end of the glue gun barrel, depending on the spraying requirements. When the V-shaped nozzle is installed, the spray pattern is V-shaped when viewed from the side; when the hook-shaped nozzle is installed, the spray pattern is √-shaped when viewed from the side. By using two different nozzles separately, the functionality is expanded. The V-shaped nozzle can spray the adhesive in a fan shape, and by rotating the nozzle, it can effectively complete horizontal or vertical planar adhesive spraying operations. The hook-shaped nozzle allows the glue gun to be held flat and sprayed upwards, achieving special operation requirements such as top spraying. This solution effectively solves the drawback of the V-shaped nozzle, which requires the hand to be raised when spraying upwards, and the construction worker is exposed to the bottom of the spraying surface, resulting in adhesive spilling onto their body. By freely switching between the two nozzles, it is possible to achieve all-round adhesive spraying work in all directions. Attached Figure Description

[0027] Please see Figure 1-6 As shown, a multi-purpose nozzle for polyurethane foam sealant includes: a glue gun body, which includes a threaded tube 6 and a glue gun barrel 11. A storage component is provided at the top of the threaded tube 6. A nozzle assembly is provided at one end of the glue gun barrel 11, and one end of the glue gun barrel 11 is provided with a threaded opening. The nozzle assembly includes a mounting plate 7, a V-shaped nozzle 8, a lever 9, a hook-shaped nozzle 10, and a threaded sleeve 15. The V-shaped nozzle 8 and the hook-shaped nozzle 10 are both embedded inside the mounting plate 7. A nozzle is provided at one end of the V-shaped nozzle 8 and the hook-shaped nozzle 10. The nozzle of the V-shaped nozzle 8 is V-shaped, and the nozzle of the hook-shaped nozzle 10 is √-shaped. A threaded sleeve 15 is provided at the other end of the V-shaped nozzle 8 and the hook-shaped nozzle 10. A lever 9 is fixedly installed on one outer wall of the mounting plate 7. The threaded sleeve 15 is threadedly and movably sleeved on the outside of the threaded opening.

[0028] Specifically, by incorporating a nozzle assembly and adding an external nozzle to the glue gun, the cylindrical glue can be compressed using the nozzle shape, resulting in a spray-like application. This allows for a thin layer of glue to be spread evenly on the plate-like surface, significantly increasing the bonding area while also saving glue. During use, the threaded sleeves 15 of the V-shaped nozzle 8 and the hook-shaped nozzle 10 are threadedly and movably fitted onto one end of the glue gun barrel 11, according to the spraying requirements. When the V-shaped nozzle 8 is installed, the spray pattern, viewed from the side, is V-shaped; when the hook-shaped nozzle 10 is installed, the spray pattern, viewed from the side... The design is √-shaped, allowing for the expansion of functionality through the separate use of two nozzles. The V-shaped nozzle enables the adhesive to be dispensed in a fan shape, and by rotating the nozzle, it can effectively complete horizontal or vertical planar adhesive spraying operations. The hook-shaped nozzle 10 allows the glue gun to be held horizontally and sprayed upwards, achieving special operation requirements such as top spraying. This solution effectively solves the drawback of the V-shaped nozzle, which requires the hand to be raised when spraying upwards, causing the worker to be exposed at the bottom of the spraying surface and the adhesive to spill onto their body. By freely switching between the two nozzles, it is possible to achieve all-round adhesive spraying work in all directions.

[0029] In this embodiment, the glue gun body also includes a glue gun handle 1, a flow switch 2, a mounting bracket 3, a connecting tube 12, a push rod 13, and a control wrench 14. The top of the glue gun handle 1 is fixedly connected to one end of the mounting bracket 3, and the other end of the mounting bracket 3 is fixedly connected to the connecting tube 12. One end of the push rod 13 is movably inserted into the interior of the connecting tube 12, and the other end of the push rod 13 is fixedly connected to the flow switch 2. The top of the control wrench 14 is movably connected to the middle part of the mounting bracket 3 through a rotating shaft, and the control wrench 14 is limited and movably sleeved on the outside of the push rod 13.

[0030] Specifically, when using it, hold the glue gun handle 1 with your hand, and then pull the control lever 14 with your fingers, which will move the push rod 13 so that the glue can be pushed and sprayed out through the nozzle. The total stroke of the push rod 13 can be controlled by adjusting the flow switch 2, thereby controlling the flow rate of the glue. The technology used is existing technology, such as glue guns and other equipment.

[0031] The storage assembly includes an output head 5 and a bottle body 4. The bottle body 4 is filled with polyurethane foam sealant. The bottom end of the bottle body 4 is fixedly connected to the output head 5. The output head 5 is threaded into the top end of a threaded tube 6. The bottom end of the threaded tube 6 is connected to a connecting tube 12. The other end of the connecting tube 12 is connected to a glue gun barrel 11.

[0032] Specifically, the output head 5 with the polyurethane foam sealant bottle 4 is threaded into the threaded tube 6, which facilitates the output of polyurethane foam sealant and also makes it easy to replace quickly.

[0033] In summary, compared with existing technologies, this multi-purpose polyurethane foam sealant spray nozzle has at least the following advantages: By incorporating a spray nozzle assembly and adding an external spray nozzle to the glue gun, the cylindrical adhesive can be compressed and sprayed in a mist form. This allows for a thin layer of adhesive to be applied evenly to the slab-like surface, significantly increasing the bonding area while also saving adhesive. During use, the threaded sleeves 15 of the V-shaped spray nozzle 8 and the hook-shaped spray nozzle 10 are threadedly and movably fitted onto one end of the glue gun barrel 11, according to the spraying requirements. When the V-shaped spray nozzle 8 is installed, the spray pattern, when viewed from the side, is V-shaped; when the hook-shaped spray nozzle 10 is installed... When the head 10 is installed, its spray pattern is √-shaped when viewed from the side. By using the two nozzles separately, the functions can be expanded. The V-shaped nozzle can make the glue spray out in a fan shape. By rotating the nozzle, it can complete horizontal or vertical planar glue spraying operations. The hook-shaped nozzle 10 can make the glue gun hold flat and spray upward to achieve special operation requirements such as top spraying. This solution effectively solves the drawback of the V-shaped nozzle spraying upward, which requires the hand to be raised and the construction worker to be exposed at the bottom of the spraying surface, and the glue will spill onto the body. By freely switching between the two nozzles, it is possible to achieve all-round glue spraying work in all directions.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
