Description

Technical Field

[0001] This utility model relates to the field of water bottle technology for vehicles, and in particular to an expansion water bottle with an open structure. Background Technology

[0002] Currently, in mass production, automotive expansion tanks are typically manufactured by injection molding the upper and lower bodies separately, and then assembling them into a single unit through vibration friction welding or ultrasonic welding to achieve the required sealing performance at high temperatures. During the product development and prototype manufacturing stage, 3D printing is generally used to create the entire unit, ensuring structural strength.

[0003] Because some expansion tanks have complex structures and numerous internal partitions, the powder inside cannot be cleaned from the whole-piece printing process. Therefore, the following manufacturing process is usually adopted: first, the upper and lower tank bodies are printed separately and then glued together, with the connection points reinforced with screws. However, this process results in products with lower structural strength compared to those made entirely from a single piece, and the adhesive is at risk of failure under long-term high-temperature vibration, failing to meet the requirements for vehicle testing.

[0004] In summary, the existing manufacturing process for expansion kettles makes it difficult to remove internal powder without reducing the structural strength of the product. Utility Model Content

[0005] In view of this, it is necessary to provide an expansion kettle with an open structure to solve the problem that the existing manufacturing process of expansion kettles makes it difficult to clean the powder inside the product without reducing the structural strength of the product.

[0006] This utility model provides an expansion kettle with an open structure, including a kettle body and a plug. The kettle body is integrally formed, and the top of the kettle body has several cleaning holes facing the powder area inside. Several plugs are connected to the cleaning holes of the kettle body one by one to seal the cleaning holes.

[0007] Furthermore, the plug includes a cover body, which is bonded to the inner wall of the cleaning hole via sealant.

[0008] Furthermore, the lid is T-shaped, the cleaning hole is a stepped groove, the inner diameter of the stepped groove increases in the direction pointing outward from the pot body, and the lid is fitted into the stepped groove.

[0009] Furthermore, the plug also includes an arc-shaped buckle and an anti-detachment buckle. The arc-shaped buckle is fixedly connected to the top edge of the cover body, and the anti-detachment buckle is disposed at the inner edge of the top of the cleaning hole. The arc-shaped buckle can be rotated to a position offset from the anti-detachment buckle, or can be rotated to be engaged in the gap formed between the anti-detachment buckle and the inner wall of the cleaning hole.

[0010] Furthermore, there are two of each of the arc-shaped buckles and the anti-detachment buckles. The two arc-shaped buckles are arranged opposite each other on both sides of the cover, and the two anti-detachment buckles are arranged opposite each other on the inner edge of the cleaning hole. The two arc-shaped buckles can pass through the gap between the two anti-detachment buckles to the position where they abut against the inner bottom wall of the cleaning hole, and the two arc-shaped buckles can rotate to the position where they abut against the two anti-detachment buckles respectively.

[0011] Furthermore, it also includes a limiting block disposed on one side of the arc-shaped buckle along its rotation direction, the limiting block being able to rotate to a position abutting against the anti-detachment buckle, and a ramp being provided on the other side of the arc-shaped buckle along its rotation direction.

[0012] Furthermore, the outer wall of the cover is formed with an annular adhesive groove.

[0013] Furthermore, it also includes a hexagonal boss fixedly connected to the center of the top of the cover.

[0014] Furthermore, the number of cleaning holes is multiple.

[0015] Furthermore, the cleaning hole is located above the maximum liquid level line of the vessel body.

[0016] Compared with existing technologies, the top of the kettle body has a cleaning hole facing the powder area inside. Cleaning tools can be inserted into the powder area inside the kettle body through the cleaning hole. After the cleaning tools have cleaned the powder, the cleaning hole is sealed with a plug, thus completing the entire manufacturing process of the expansion kettle. This not only makes it easier to clean the powder, but also ensures the structural strength of the product because the kettle body is made in one piece. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0021] like Figure 1As shown, the present invention provides an expansion kettle with an open structure, including a kettle body 100 and a plug 200. The kettle body 100 is integrally formed, and the top of the kettle body 100 has a plurality of cleaning holes 110 facing the powder area inside it. A plurality of plugs 200 are connected to the cleaning holes 110 of the kettle body 100 in a one-to-one correspondence to seal the cleaning holes 110.

[0022] In practice, the top of the kettle body 100 is provided with a cleaning hole 110 facing the powder area inside. A cleaning tool can be inserted into the powder area inside the kettle body 100 through the cleaning hole 110. After the cleaning tool has cleaned the powder, the cleaning hole 110 is closed by the plug 200, thus completing the entire production process of the expansion kettle. This not only makes it convenient to clean the powder, but also ensures the structural strength of the product because the kettle body 100 is made in one piece.

[0023] Obviously, in this embodiment, the cleaning hole 110 differs from the water inlet of the expansion pitcher. The water inlet is generally singular, while the number of cleaning holes 110 may vary depending on the powder removal requirements. Furthermore, after the powder is removed, the plug 200 completely seals the cleaning hole 110, establishing a sealed and fixed connection between the two, eliminating the need to reopen the cleaning hole 110. The cap at the water inlet of the expansion pitcher is detachably connected to the water inlet. It is easy to understand that, if needed, the water inlet of the expansion pitcher can also be used for powder removal.

[0024] In this embodiment, the pot body 100 is integrally formed, and a cleaning hole 110 is provided on the top of the pot body 100, facing the powder area inside. In one embodiment, the diameter of the cleaning hole 110 is 15mm, which ensures that the powder cleaning tool can enter smoothly and clean the powder inside.

[0025] The kettle body 100 structure, which is made in one piece by 3D printing, has good structural strength. Since there are many partitions inside the kettle body 100 structure, powder is present during the printing process. Therefore, a cleaning hole 110 is opened on the top of the kettle body 100, facing the powder area inside, to facilitate the cleaning of powder.

[0026] After the powder is removed, the cleaning hole 110 is sealed by the plug 200 in this embodiment.

[0027] In this embodiment, the plug 200 includes a cover body 210, which is bonded to the inner wall of the cleaning hole 110 via a sealant. The sealant can be AB glue.

[0028] In one embodiment, the lid 210 is T-shaped, the cleaning hole 110 is a stepped groove, the inner diameter of the stepped groove increases in the direction pointing outward of the pot body 100, and the lid 210 is fitted into the stepped groove.

[0029] like Figure 2-3As shown, the plug 200 also includes an arc-shaped buckle 220 and an anti-detachment buckle 230. The arc-shaped buckle 220 is fixedly connected to the top edge of the cover body 210, and the anti-detachment buckle 230 is disposed at the inner edge of the top of the cleaning hole 110. The arc-shaped buckle 220 can rotate to a position offset from the anti-detachment buckle 230, or can rotate to be engaged in the gap formed between the anti-detachment buckle 230 and the inner wall of the cleaning hole 110. The arc-shaped buckle 220 and the anti-detachment buckle 230 ensure that the plug 200 will not loosen under high temperature.

[0030] In this embodiment, there are two arc-shaped buckles 220 and two anti-detachment buckles 230. The two arc-shaped buckles 220 are arranged opposite to each other on both sides of the cover 210, and the two anti-detachment buckles 230 are arranged opposite to each other on the inner edge of the cleaning hole 110. The two arc-shaped buckles 220 can pass through the gap between the two anti-detachment buckles 230 to the position where they abut against the inner bottom wall of the cleaning hole 110, and the two arc-shaped buckles 220 can rotate to the position where they abut against the two anti-detachment buckles 230 respectively.

[0031] To ensure that the arc-shaped buckle 220 can slide precisely into the gap formed between the anti-detachment buckle 230 and the inner wall of the cleaning hole 110, this embodiment also includes a limiting block 221 disposed on one side of the arc-shaped buckle 220 along its rotation direction. The limiting block 221 can rotate to a position that abuts against the anti-detachment buckle 230. A ramp 222 is provided on the other side of the arc-shaped buckle 220 along its rotation direction to prevent large hard friction between the arc-shaped buckle 220 and the anti-detachment buckle 230 when the arc-shaped buckle 220 slides into the bottom of the anti-detachment buckle 230.

[0032] like Figure 3 As shown, in this embodiment, the outer wall of the cover 210 has an annular adhesive groove 211. The height of the adhesive groove 211 is 1 mm and the depth of the adhesive groove 211 is 0.5 mm. The sealant can be filled into the adhesive groove 211 to ensure effective sealing.

[0033] To facilitate rotation of the cover 210, this embodiment also includes a hexagonal boss 240 fixedly connected at the center of the top of the cover 210, which is convenient for rotational installation using a sleeve tool.

[0034] In this embodiment, there are multiple cleaning holes 110. The cleaning holes 110 are located above the maximum liquid level line 120 of the pot body 100 and will not affect the water flow in the pot body 100.

[0035] Workflow: The kettle body 100 is manufactured as a single piece. The internal partition structure of the kettle body 100 is analyzed to determine which areas cannot be cleaned of internal powder after printing. An opening is made at the top of the maximum liquid level line 120 in this area, and a plug 200 is designed. The plug 200 is printed and manufactured separately from the kettle body 100. After the powder inside the kettle body 100 is cleaned, high-temperature resistant AB glue is applied to the plug 200. The plug 200 is rotated into place using a sleeve tool. The remaining gaps are filled with AB glue. The kettle is then heat-cured in a constant temperature oven for 2-3 hours to ensure sealing and structural strength.

[0036] Compared with the prior art, the top of the kettle body 100 has a cleaning hole 110 facing the powder area inside. A cleaning tool can be inserted into the powder area inside the kettle body 100 through the cleaning hole 110. After the cleaning tool has cleaned the powder, the cleaning hole 110 is closed by the plug 200, thus completing the entire manufacturing process of the expansion kettle. This not only makes it convenient to clean the powder, but also ensures the structural strength of the product because the kettle body 100 is made in one piece.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
