Abstract

A combination grill brush includes a brush head and a brush handle, in which brush head contains a hair portion and a cover portion and both are in form of stationary combination. The front end of the brush head becomes an overhang and the rear end provides the springy clasping edge. The brush handle is a hollow tube with one end enclosed and one hook ring on the end. The said brush head can be repeatedly pushed in and pulled out of the brush rod with the springy clasping edge, providing brush head replacement for damaged one.

Description

BACKGROUND OF THE INVENTION
• 1. Field of the Invention[0001]
• The invention relates to a structure of grill brush, which includes a brush head and a brush handle being designed to be detachable each other to hereby provide the individual replacement of either damaged part.[0002]
• 2. Description of the Background Art[0003]
• In occasion of grill, the grill brush used to dip sauce and paint food is one of the indispensable tools. As a result of the functions of dipping sauce and painting food, grill brush must have portion similar to brush hairs and handle capable of fastening hairs facilitating operation. In view of this, the traditional paint brush for wall painting has been alternatively applied to be the grill brush. When viewing the structure of the existing paint brush[0004]1 (as shown in FIG. 1), it consists of ahair portion10 and abrush handle portion11 connected and wrapped withthin iron plate12. The front end ofthin iron plate12 is formed withclipping structure13 to fasten thehair portion10, andnail14 is used to go throughthin iron plate12, fastening the hair portion over the front end ofbrush handle portion11.
• As mentioned in the said[0005]traditional paint brush1, thehair portion10 andbrush handle portion11 is combined indirectly bythin iron plate12 instead of being directly combined each other. Besides, thethin iron plate12 covers around thehair portion10 andbrush handle11 in way of envelope. Hence after operation a while, the wrapping structure ofthin iron plate12 gets loose, thus causing unfastened betweenhair portion10 andbrush handle11, further affecting the controllability ofbrush handle11 towardhair portion10 and consequently failing to paint superior surface as wish. Thetraditional paint brush1 has another problem thathair portion10 absorbs paint after long while and water as well, making the glue in the end binding the hairs brittle and hair falling off gradually accordingly. When the hairs are falling off and the brush no longer works properly, brush handle may still as good as new one. It is wasteful if discarding the whole brush, while it is useless to keep the brush handle. Judging from all the drawbacks of traditional paint brush, the grill brush taking over the structure certainly comes into the same issue.
SUMMARY OF THE INVENTION
• Two drawbacks that happen in traditional grill brush are that the unsteady coupling of brush handle and hair generates slackness between hair and handle after operating a while, making the brush no longer have effective operation control, also hairs easily tend to go off due to operation environment; it is quite wasteful and doesn't fulfill environmental protection if simply discarding the whole grill brush. In view of this, the invention provides a grill brush with new structure that is composed of a brush head and a brush handle, in which the brush head also includes a hair portion and a cover portion in permanent binding state. The cover portion is formed with a blocking overhang over one end installed with hair and the opposite end provided with springy clasping edge capable of properly having radial contraction. With the said clasping edge of the cover portion of the said brush, the brush head and brush rod can be easily assembled or taken apart, thus allowing to replace the damaged part with new one and keep the working part through simple disassembling to fulfill the environment protection and cost saving when either one of the brush head or brush handle is ruined. Moreover, the hairs of the invention are fixed at the cover portion and then use cover portion to cap the brush handle. As such, the brush can be deemed as the direct combination of the brush head and brush handle capable of providing better structure in strength than the traditional grill brush and making the operation more handy.[0006]
BRIEF DESCRIPTION OF THE DRAWINGS
• FIG. 1 relates to the partial front cross sectional diagram of traditional grill brush.[0007]
• FIG. 2 relates to the 3D diagram of structure decomposition associated with the invention.[0008]
• FIG. 3 relates to the font cross sectional diagram of the structure assembly portion associated with the invention.[0009]
DESCRIPTION OF THE PREFERRED EMBODIMENTS
• The better implementation structure of the invention as shown in FIGS. 2 and 3 is constituted by a[0010]brush head2 and abrush handle3, in whichbrush head2 also includes ahair portion21 and acover portion22 that are bonded with glue or formed as one body when forming thecover portion22. One end of thecover portion22 is theblocking overhang221 and the other end is claspingedge222. The claspingedge222 uses the severalaxial grooves223 to provide radial contraction and recovery elasticity and to form a slightlybulgy overhang224. The brush handle is a tube where the tail end is enclosed and is put ahang ring31.
• In accordance with the said structure,[0011]brush head2 directly pushes in the open end of thebrush handle3 up to theoverhang221 and is locked over theopen end32 ofbrush handle3. When pushing in the claspingedge222 will have slight radial contraction. Together with the declined design of thecover portion22 after clocking overhang, cover portion can smoothly push inside brush handle against the inner wall ofbrush handle3 by means of bouncing force of the claspingedge222 so thatbrush head2 can be securely pushed in thebrush handle3. For the combined structure ofbrush head2 andbrush handle3, the slightlybulgy overhand224 over the tail end of thecover portion22 of thebrush head2 allows thecover portion22 to fully combine with the inner wall ofbrush handle3 without having to sacrifice the combined stability. When pulling out thebrush head2, the slightlybulgy overhang224 can also allow pull easily when pulling off thebrush head2. Such function helps conduct individual part replacement when either one of thebrush head2 orbrush handle3 is broken. In addition,brush head2 combining thebrush hair portion21 andcover portion22 as a whole further combines withbrush handle3 loosely withbrush head2, hencebrush hair portion21 can firmly connect withbrush handle3 withcover portion22, resolving the unsteady phenomenon obviously found in structure of the brush hairs and brush handle of the traditional grill brush.

Claims (3)

What is claimed is:

1. A combination grill brush, which is composed of a brush head loosely enveloped on a brush handle and is characterized by brush head including a brush hair portion and a cover portion mutually bundled in stationary form, in which the portion of cover portion adjacent to brush hairs is formed with a block overhang and formed with a clasping edge on the opposite side with several springy plates, and the portion of the clasping edge in the proximity of the end portion is formed with a round of slightly bulgy overhang; brush handle, which is a tube with a open end and a enclosed end, wherein the enclosed end is provided with a hang ring. The said brush head pushes in the open end of the brush handle with one end of the clasping edge all the way to the block overhang and is against the open end of the brush handle.

2. A combination grill brush in accordance with item1, wherein one end of the brush head is formed with several indirect grooves axially as springy clasping edges.

3. A combination grill brush in accordance with item1, wherein the brush hair portion is securely fastened at one side of the hollow cover portion to form the brush head.
