Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, specifically to a paper stick cleaning brush mold and cleaning brush. Background Technology

[0002] Oral hygiene sometimes requires the aid of objects. Brushing teeth and rinsing the mouth alone are not enough to clean the oral cavity. Thick phlegm on the surface of the tongue and in the mouth requires a suitable object to help clean it. Oral and dental doctors also often need suitable objects to help clean foreign objects in the mouths of patients being examined or treated in clinical practice.

[0003] Currently, the commonly used disposable gauze on the market is made of a pleated brush head, a handle, and hot melt adhesive. The pleated brush head is shaped by sewing the gauze and is fixed to the handle by hot melt adhesive.

[0004] For example, Chinese patent CN212488971U discloses a multi-functional gauze toothbrush, including a hand-held brush handle and a gauze brush head, with the gauze brush head in an inverted U-shape covering the end of the hand-held brush handle.

[0005] Typically, gauze brush heads are made of gauze folded into multiple rows of pleats, with a certain uneven structure to scrape off and remove oral residue. However, the uneven effect of this type of gauze brush head is not obvious, and the effect of scraping off oral residue is poor. Utility Model Content

[0006] The purpose of this invention is to provide a paper stick cleaning brush mold and a cleaning brush to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A paper stick cleaning brush mold includes two or more sets of support parts arranged in a straight line, with a recessed area formed between two adjacent support parts, and an extension part widened at the end of each support part, with an avoidance area formed between two adjacent extension parts on the same side.

[0009] A cleaning brush made from a paper stick cleaning brush mold includes a handle and a brush head folded and wrapped around the end of the handle. The folded brush head is fixed by welding to form a welding line, which crosses the handle. The two ends of the welding line are located on opposite sides of the handle, and the ends of the welding line are widened.

[0010] Preferably, the end of the hand handle is provided with a flat portion having a flat structure, and a thin sheet widening portion extending outward from the outer edge of the flat portion.

[0011] Preferably, the widened portion of the thin sheet is provided in three groups on the front, left and right sides of the flat portion.

[0012] Preferably, the thickness of the widened portion of the sheet is less than the thickness of the flat portion.

[0013] Preferably, the brush head material is gauze, knitted fabric, degreased gauze, flannel, wrapped gauze, flocked fabric, or heat-pressed fabric.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a recessed area formed between two adjacent support parts of the mold. This recessed area accommodates the ridges of the brush head during ultrasonic welding, resulting in a weld line on the brush head after ultrasonic welding, and a more pronounced recessed shape between the ridges of the uncompressed brush head. This pleated brush head more easily scrapes and removes oral residue, resulting in better removal of oral residue.

[0016] By widening the end of the mold's support section to form an extension, the brush head expands its space to accommodate oral residue after welding. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] A paper stick cleaning brush mold, such as Figures 5-6 As shown, it includes a base and support parts 400 arranged in a row and fixed to the surface of the base. The upper surface of the support parts 400 is arc-shaped to place the brush head 200 and the hand handle 100 for subsequent ultrasonic welding work. The top of the outermost support part 400 is flush with the other support parts 400 and its height is slightly higher. The outermost support part 400 is used to limit the placement of the brush head 200 and the hand handle 100.

[0030] The arc-shaped structure on the upper surface of the support part 400 is adapted to the hand handle 100.

[0031] A recessed area 500 is formed on the base surface between two adjacent support parts 400. An extension part 600 is formed by widening the end of the support part 400. The extension part 600 has a "T" or "L" shaped structure. A clearance area 700 is formed between the ends of the support parts 400 on the same side.

[0032] How to use:

[0033] The brush head 200 is folded in half and wrapped around the end of the handle 100, then placed on the arc-shaped upper surface of the support 400. Two molds cooperate to form a recessed area 500 that interlocks with the brush head 200, securing it to the end of the handle 100. For paper sticks or environmentally friendly synthetic materials, a groove must be pressed into the end of the handle 100. This groove can be formed using the ribs of the support 400. The ribs of the support 400 can be modified into different shapes or dotted patterns to secure the gauze to the paper stick. The brush head 200 is simultaneously pressed into the groove to prevent it from falling off. Ultrasonic welding is then performed to fix the folded brush head 200 to the end of the handle 100. During ultrasonic welding, the support 400 and its extended portion 600 form a welding line 300 on the outer surface of the brush head 200.

[0034] A cleaning brush, such as Figures 1-4 As shown, it includes a handle 100 and a brush head 200. The brush head 200 is folded into a multi-row pleated structure and shaped by sewing with cotton yarn. Then, the brush head 200 is folded in half and covered and fixed to the end of the handle 100 by ultrasonic welding. During the ultrasonic welding process, multiple welding lines 300 are formed on the brush head 200. The end of the handle 100 covered by the brush head 200 is designed as a flat part 101 with a flat structure.

[0035] The integrated design of the handle 100, flat portion 101, and thin-sheet widened portion 102 can be injection molded or made of PP, PVC, ABS, paper, wood, bamboo, or other synthetic materials. This allows the support portion 400 to apply external force and press a shallow indentation onto the outer surface of the handle 100. The flat portion 101 facilitates the folding of the brush head 200, which covers its opposite sides, and allows for subsequent ultrasonic welding across the flat portion 101. The thinner thin-sheet widened portion 102 not only welds to the brush head 200 as a single unit but also prevents the brush head 200 from detaching from the end of the handle 100.

[0036] The raised part of the brush head 200 with a pleated structure is designated as a ridge 201, and the recessed part is designated as a trough 202.

[0037] like Figures 3-4 As shown, the welding line 300 starts from the left side of the flat portion 101 and extends along the length of the handle 100, crossing the flat portion 101 to the right side of the flat portion 101.

[0038] During ultrasonic welding, the ridges 201 of the brush head 200 at the end of the handle 100 are positioned opposite each other in the recessed area 500, and the brush head 200 in the recessed area 500 is not squeezed and protruded, resulting in a better effect; the brush heads 200 on the left and right sides of the end of the handle 100 are positioned in the avoidance area 700.

[0039] If the welding line 300 coincides with the fold 202, the welding line 300 can further reinforce and shape the fold 202 after ultrasonic welding, forming a hook structure with a deeper and more stable depression shape.

[0040] The two adjacent sets of support portions 400 and their end extension portions 600 cooperate to form a relatively independent and more obvious protrusion on the brush head 200 located in the recessed area 500 after welding.

[0041] The ends of the welding line 300 are widened (relative to the length direction of the handle 100), so that the welding line 300 has an "I" shaped outline. The widening of the ends of the welding line 300 expands the space for accommodating oral residue, which can greatly improve the ability to accommodate oral residue arranged along the direction of the handle 100.
