[0002] With the development of the interior decoration industry, the beauty seam structure is often used between the decorative panels of the wall and the floor. The beauty seam structure has many excellent characteristics of beauty, waterproofness, and mildew resistance, and its application is becoming more and more extensive. When beautifying between ceramic tiles or stone decorative panels, a beauty seam glue gun is usually used, and the glue nozzle of the gun nozzle is aimed at the gap of the beauty seam for injection. Most of the existing gun nozzles adopt a circular glue hole structure. In order to smoothly discharge glue, the aperture of the glue hole is often designed to be larger. In this way, the glue nozzle cannot be inserted into the gap of the beauty seam for injection. When the glue nozzle injects glue outside the gap, in order to fully inject glue, excess glue often leaks out, causing waste and environmental pollution, which brings inconvenience to the beauty seam operation. Therefore, it is necessary to develop a gun nozzle on a beauty seam glue gun that can accurately inject glue and discharge glue smoothly. Utility Model Content

[0029] Embodiment 1

[0030] See also Figures 1 to 3 In one embodiment of the present application, a gun nozzle for a seam sealant gun is provided, which includes: a glue discharge head 110, a tube body 120 and a connector 130.

[0031] The glue discharge head 110 and the connector 130 are respectively connected to two ends of the tube body 120 , and the connector 130 is used to connect the caulking agent tube installed on the glue gun body.

[0032] The sealant in the sealant tube can flow into the glue discharge head 110 through the connector 130 and the tube body 120 in sequence.

[0033] The outer diameter of the glue discharge head 110 gradually decreases from one end of the glue discharge head 110 close to the tube body 120 to the other end of the glue discharge head 110 away from the tube body 120 to form a conical structure; the glue discharge head 110 has a glue discharge nozzle 111 at the end away from the tube body 120, and the cross-sectional shape of the glue discharge nozzle 111 is elliptical. An elliptical glue discharge hole 112 is provided on the glue discharge nozzle 111, and the width of the glue discharge nozzle 111 is smaller than the width of the beauty seam so that the glue discharge nozzle 111 can be inserted into the gap to inject glue.

[0034] At least one V-shaped glue outlet groove 113 is downwardly opened on the circumference of the glue outlet nozzle 111 for smooth glue outlet, and the V-shaped glue outlet groove 113 is connected to the elliptical glue outlet hole 112 .

[0035] The glue nozzle 111 can be inserted into the gap between the building decoration plates to inject glue into the gap. The size of the elliptical glue hole 112 is small, and the glue discharge from the elliptical glue hole 112 alone will result in poor glue discharge. When the gun nozzle of the seam glue gun of this embodiment is inserted into the gap between the building decoration plates, the seam glue can flow into the gap through the elliptical glue hole 112 and the V-shaped glue groove 113.

[0036] The gun nozzle for the seaming glue gun of the present embodiment is connected to the seaming agent tube installed on the glue gun body through the connector 130, and the seaming agent in the seaming agent tube can flow into the glue head through the connector 130 and the tube body 120 in sequence; by reducing the size of the glue head 110 away from the end of the tube body 120, the glue nozzle 111 can be inserted into the gap of the seaming to fill the seaming agent in the gap, thereby effectively improving the fullness of the filling and improving the seaming effect, and the seaming agent is not easy to be applied outside the gap, reducing the waste of the seaming agent and reducing the workload of subsequent cleaning; the V-shaped glue outlet groove 113 cooperates with the elliptical glue outlet hole 112 to effectively improve the fluidity of the seaming agent and facilitate the outflow of the seaming agent. Therefore, the present application has the characteristics of novel structure, precise glue injection, and smooth glue discharge.

[0037] In some embodiments, see Figure 1 and Figure 3 The glue outlet nozzle 111 is flat-mouthed so as to be easily inserted into the gap between the building decoration panels.

[0038] In some embodiments, the cross-section of the glue nozzle 111 along the horizontal direction is substantially elliptical, and the minimum outer diameter of the glue nozzle 111 is between 1-2 mm.

[0039] The minimum outer diameter of the glue discharge nozzle 111 refers to the outer diameter along the minor axis direction.

[0040] In some embodiments, a V-shaped glue outlet groove 113 is formed on the periphery of the glue outlet nozzle 111 .

[0041] In some embodiments, two V-shaped glue outlet grooves 113 are formed on the periphery of the glue outlet nozzle 111 , and the two V-shaped glue outlet grooves 113 are symmetrically arranged.

[0042] Furthermore, the glue outlet head 110 is in an inclined state when in use, and the caulking agent flows out into the gap through one of the V-shaped glue outlet grooves 113, and the other V-shaped glue outlet groove 113 is connected to the outside air, thereby effectively improving the fluidity of the caulking agent.

[0043] The operator can select the glue outlet groove in a suitable direction according to the use environment and insert it into the gap between the building decoration plates.

[0044] In some embodiments, see Figure 2 The opening angle of the V-shaped glue outlet groove 113 is α, and the opening angle α of the V-shaped glue outlet groove 113 is between 30-45°.

[0045] Preferably, when the opening angle α of the V-shaped glue outlet groove 113 is 40°, the fluidity of the caulking agent is better, and it is not easy for too much caulking agent to flow out of the V-shaped glue outlet groove 113 .

[0046] In some embodiments, the tube body 120 and the glue dispensing head 110 are fixedly connected by integral molding.

[0047] In some embodiments, the glue dispensing head 110 is detachably connected to the tube body 120 to facilitate replacement of different glue dispensing heads 110 .

[0048] Exemplarily, a connector (not shown) is provided at one end of the glue dispensing head 110 away from the glue dispensing nozzle 111 , and the connector is pluggably disposed in the tube body 120 , so that the glue dispensing head 110 and the tube body 120 are detachably connected.

[0049] In some embodiments, the tube body 120 and the connector 130 are fixedly connected by integral molding.

[0050] In some embodiments, see Figure 4 A connecting portion 131 is provided inside the connecting body 130, and the connecting portion 131 is used to connect the seam-beautifying agent tube.

[0051] Exemplarily, the connection portion 131 is an internal thread, and the connection portion 131 is used to be screwed and connected to the external thread on the caulking agent tube.

[0052] In some embodiments, see Figure 4 The tube body 120 has a mixing channel 121 therein, the mixing channel 121 is connected to the elliptical glue outlet hole 112 and the V-shaped glue outlet groove 113, and the mixing channel 121 has a guide member 140 built in for mixing different components of the caulking agents.

[0053] When the caulking agent tube injects two caulking agents with different components into the mixing channel 121 , the flow guide 140 can increase the contact area and contact time of the two caulking agents to improve the uniform mixing degree of the two caulking agents.

[0054] In some embodiments, the guide member 140 has a spiral flow channel, and the seam beautifying agent flows through the spiral flow channel from one end of the mixing channel 121 close to the connector 130 to one end of the mixing channel 121 close to the glue outlet head 110 .

[0055] In some embodiments, the peripheral side of the guide member 140 is disposed against the inner wall of the mixing channel 121 to prevent the caulking agent from entering between the peripheral side of the guide member 140 and the inner wall of the mixing channel 121, thereby ensuring that the caulking agent flows in the spiral flow channel.

[0056] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.
