Description

Technical Field

[0001] This application relates to the field of grout guns, and more particularly to a grout gun with automatic glue mixing function. Background Technology

[0002] In the fields of architectural decoration and home renovation, grout sealing is an important process. It not only enhances the aesthetics of tiling materials such as tiles but also provides waterproofing, stain resistance, and mildew prevention. As the core material for grout sealing, the performance and ease of use directly affect the sealing effect and construction efficiency. Regarding the mixing of grout sealants, many are composed of two or more components, such as the common AB sealant.

[0003] Regarding the aforementioned technologies, the inventors believe that traditional grout guns struggle to ensure thorough and uniform mixing of the two adhesives, leading to uneven curing, inconsistent color, and insufficient strength after grouting. This severely impacts the quality and lifespan of the grout. Furthermore, the viscosity of the grout is significantly affected by temperature. At low temperatures, the viscosity increases substantially, reducing fluidity and making dispensing difficult. This increases application resistance, not only increasing the workload for installers but also causing discontinuous dispensing and interruptions, affecting the smoothness and aesthetics of the grout lines. Utility Model Content

[0026] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0029] This application discloses an automatic glue-mixing grout gun. (Refer to...) Figure 1-3An automatic grout mixing caulking gun includes a caulking gun body 1, a caulking bottle 2 inserted into the caulking gun body 1, and a mixing nozzle 3 disposed at the opening of the caulking bottle 2. It also includes: a fixing unit 4 disposed on the caulking gun body 1 for fixing the caulking bottle 2 placed on the caulking gun body 1; and a heating unit 5 disposed at the connection between the caulking bottle 2 and the mixing nozzle 3 and connected to the caulking gun body 1 for heating the grout inside the caulking bottle 2.

[0030] During operation, the AB glue bottle 2 is installed in the glue gun body 1, and the AB glue bottle 2 is fixed to the glue gun body 1 by the fixing unit 4. The operator presses the glue gun body 1, causing the grout to move from the AB glue bottle 2 to one side of the mixing nozzle 3. The two types of glue are mixed inside the mixing nozzle 3, and then extruded from the mixing nozzle 3, completing the glue mixing process. By setting the mixing nozzle 3 in the glue gun body 1, the different components of the grout extruded from the AB glue bottle 2 can be automatically and thoroughly mixed as they pass through the mixing nozzle 3, resulting in a uniform color of the grout and avoiding problems such as cracking and peeling due to insufficient strength. This greatly improves the overall quality and service life of the grout.

[0031] In low-temperature environments, the heating unit 5 can be fitted onto the outlet of the AB glue bottle 2 to heat the glue inside the AB glue bottle 2. The viscosity of the grout is greatly affected by temperature. In low-temperature environments, the viscosity of the grout increases and its fluidity decreases. The heating unit 5 of this grout gun is located at the connection between the glue bottle 2 and the mixing nozzle 3, which can heat the grout inside the glue bottle 2. After heating, the viscosity of the grout decreases, its fluidity increases, and the glue dispensing becomes smoother and more continuous. It can evenly fill the gaps, forming full and smooth grout lines, avoiding problems such as broken lines and unevenness caused by discontinuous glue dispensing, and making the grouting effect more beautiful.

[0032] In one embodiment, the glue bottle 2 has an insert 22 on the side connected to the glue gun body 1. A slot 101 is provided on the side wall of the glue gun body 1 relative to the insert 22. The insert 22 engages with the slot 101, allowing the insert 22 to be inserted into the slot 101. A dispensing head 21 is provided on the side of the glue bottle 2 connected to the mixing nozzle 3. A plug 23 for fixing the mixing nozzle 3 is provided on the side of the glue bottle 2 away from the glue gun body 1. A protrusion is fixedly connected to the end of the mixing nozzle 3 near the plug 23, and the protrusion can extend into the plug 23.

[0033] Reference Figures 4-6 The AB glue bottle 2 has an insert block 22 on the side connected to the glue gun body 1. This design provides precise positioning for the docking of the glue bottle 2 and the glue gun body 1. When installing the glue bottle 2, the construction personnel only need to align the insert block 22 with the corresponding slot 101 on the glue gun body 1 to quickly and accurately install the glue bottle 2 into place, which greatly shortens the installation time and improves the preparation efficiency before construction.

[0034] The design of plug 23 also makes the installation and replacement of mixing nozzle 3 very convenient. The installer only needs to align the corresponding part of mixing nozzle 3 with plug 23, gently insert it and rotate or lock it to complete the installation. When it is necessary to replace different types or specifications of mixing nozzle 3, it can also be removed quickly and easily. This convenient installation and replacement method improves the flexibility and efficiency of construction, especially when it is necessary to frequently replace mixing nozzle 3 to adapt to different grouting needs, the advantages are even more obvious.

[0035] In one embodiment, the mixing nozzle 3 includes: an outer tube 31 with a tubular structure located on the outside and a tube connector 33, the tube connector 33 being disposed on the outer tube 31, sleeved on the dispensing head 21 and snapped into the insertion groove 2301 on the plug 23; a mixing core 32 is also fixedly connected inside the outer tube 31 for mixing the glue squeezed out of the glue bottle 2; and a dispensing port 34 is disposed on the side of the outer tube 31 away from the glue gun body 1.

[0036] When installing or removing the mixing nozzle 3 from the glue bottle 2, the operator can easily grasp the outer tube 31, improving installation and removal efficiency. The pipe connector 33, located on the outer tube 31, can be fitted onto the dispensing head 21 of the glue bottle 2 and snapped into the insertion slot 2301 of the plug 23. This design achieves a tight and stable connection between the mixing nozzle 3 and the glue bottle 2. To install the mixing nozzle 3, the pipe connector 33 is inserted and fixed to the dispensing head 21. Then, the pipe connector 33 is rotated to secure it in the insertion slot 2301, completing the quick installation of the mixing nozzle 3. To remove the mixing nozzle 3, the pipe connector 33 is rotated in the opposite direction to unscrew it from the insertion slot 2301, and then pulled out of the dispensing head 21. The design of the pipe connector 33 allows the mixing nozzle to... The installation of the mixing nozzle 3 with the glue bottle 2 is very simple and quick. The construction worker only needs to align the pipe connector 33 with the glue outlet 21 and plug 23 of the glue bottle 2, gently press and rotate or push it so that the pipe connector 33 is fitted on the glue outlet 21 and snapped into the insertion groove 2301, which can complete the installation of the mixing nozzle 3, greatly saving installation time and improving construction efficiency. The mixing core 32 is set inside the outer tube 31. Its spiral structure design can fully and evenly mix the two or more components of the grout extruded from the glue bottle 2. The mixing core 32 adopts a spiral, grid or other special geometric shape. These shapes can increase the flow path and contact area of ​​the grout when passing through the mixing core 32, so that the different components of the grout can be stirred and mixed with each other during the flow process, thereby achieving a uniform mixing effect.

[0037] In one embodiment, the fixing unit 4 includes: a connecting plate 41 rotatably disposed on the glue gun body 1; a squeezing plate 42 is fixedly connected to the side of the connecting plate 41 away from the glue gun body 1, the shape of the squeezing plate 42 on the side near the glue bottle 2 is opposite to the glue bottle 2, and is used to squeeze and fix the glue bottle 2 placed on the glue gun body 1; and side ears 43, disposed on both sides of the squeezing plate 42 and fixedly connected to the glue gun body 1 by fixing bolts 44.

[0038] The connecting plate 41 is rotatably mounted on the glue gun body 1. This design gives the fixing unit 4 great flexibility. When installing the glue bottle 2, the construction personnel can freely rotate the connecting plate 41 according to the actual position of the glue bottle 2 and the installation requirements, and adjust the angle and position of the extrusion plate 42 so that it can accurately contact the glue bottle 2 and apply appropriate extrusion force. After the glue bottle 2 is installed inside the glue gun body 1, the side lug 43 is fixed to the glue gun body 1 by the fixing bolt 44, so that the glue bottle 2 is fixed inside the glue gun body 1, completing the installation of the glue bottle 2. When removing the glue bottle 2, the connecting plate 41 can be rotated first to release the extrusion on the glue bottle 2, and then the glue bottle 2 can be easily removed. This operation method reduces obstacles in the installation and disassembly process, saves time and effort, and improves construction efficiency.

[0039] In one embodiment, the heating unit 5 includes: a heating ring 51, which is sleeved on the glue bottle 2 and used to heat the sealant inside the glue bottle 2; and an insert rod 52, which is disposed on the heating ring 51 and inserted into the glue gun body 1.

[0040] The heating ring 51 is a prior art structure and will not be described in detail here. It is fitted onto the glue bottle 2 and can completely wrap the glue bottle 2. Compared with local heating, this design can ensure that the grout inside the glue bottle 2 can be uniformly heated in all directions, ensuring that the grout is heated evenly. Then, the insert rod 52 is fixed to the glue gun body 1 to complete the fixing of the heating ring 51 and the glue bottle 2.

[0041] In one embodiment, the lower end of the glue gun body 1 is provided with a base 11 for supporting the glue bottle 2; the base 11 is provided with an insertion hole 12 for inserting the plug rod 52; and the base 11 is provided with a fixing nut 13 for fixing the plug rod 52.

[0042] The lower end of the glue gun body 1 is provided with a base 11 to support the glue bottle 2. During the grouting process, the glue bottle 2 contains grout and has a certain weight. The base 11 can provide a stable support platform for the glue bottle 2, preventing the glue bottle 2 from tipping over or shifting due to its own weight or the shaking of the glue gun during construction. The insertion hole 12 on the base 11 is used to insert the insertion rod 52, providing precise positioning for the installation of the heating unit 5. When installing the heating ring 51, the construction personnel only need to align the insertion rod 52 with the insertion hole 12 and insert it to quickly and accurately install the heating ring 51 into the corresponding position of the glue bottle 2. The fixing nut 13 is rotatably set on the base 11. When the insertion rod 52 is inserted into the insertion hole 12, the fixing nut 13 is rotated to make the fixing nut 13 threadedly connected to the insertion rod 52, thereby fixing the insertion rod 52 on the base 11 and enhancing the connection between the heating unit 5 and the glue gun body 1.
