Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fish tank cleaning tools, in particular to a fish tank cleaning magnetic brush with a grindstone. Background Art
[0002] As people's living conditions gradually improve, fish farming has become an increasingly common leisure activity in people's daily lives. However, cleaning the algae growing on the inner wall of the fish tank glass is often a very troublesome task, especially the calcium dirt growing on the glass wall of the seawater aquarium is particularly stubborn and difficult to clean. The existing fish tank cleaning magnetic brush is generally equipped with a metal scraper (reference patent: CN202962917U-quickly assembled and disassembled fish tank cleaning scraper) in the inner part of the tank to scrape such stubborn dirt and algae. However, this metal scraper will be worn out after being used for a period of time, resulting in the inability to effectively scrape off the dirt, and the scraper can only be replaced. This not only causes a waste of resources, but also leads to a high cost of the fish tank cleaning magnetic brush.
[0003] Here, in order to solve the above problems, we propose a fish tank cleaning magnetic brush with a whetstone. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide a fish tank cleaning magnetic brush with a grindstone. When the scraper is worn and blunt, the built-in grindstone strip can be used to sharpen it again, so that it can be used for a longer time, reducing the cost of the fish tank cleaning magnetic brush.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:
[0006] A fish tank cleaning magnetic brush with a grindstone comprises an inner brush portion, an outer brush portion, and a blade;
[0007] The blade is installed on the inner brush part;
[0008] The inner brush part includes an inner brush housing, an inner brush housing cover and an inner magnet block; the inner brush housing is a box-shaped structure with an opening facing left, the left side is covered and fixed by the inner brush housing cover, and the inner magnet block is fixed between the inner brush housing cover and the inner brush housing;
[0009] The outer brush part comprises an outer brush housing cover, an outer brush shell, an outer magnet block and a grindstone bar; the outer brush shell is a box-shaped structure with an opening facing left, and the left side is covered and fixed by the outer brush housing cover, and the outer magnet block is fixed between the outer brush housing cover, the iron sheet and the outer brush shell; an inwardly concave groove is formed on the top of the outer brush shell, and a grindstone bar is fixedly installed in the groove; the inner magnet block and the outer magnet block have opposite poles and attract each other;
[0010] The blade and the top of the inner brush shell are integrally formed with a clamping sleeve, the knife seat is plugged into the clamping sleeve, a bayonet is fixed on the lower side of the knife seat, the bayonet is an elastic structure, and a clamping hole that cooperates with the bayonet is reserved on the clamping sleeve. The scraper is fixed on the knife seat, and the upper edge of the blade is movably connected to the wall of the fish tank.
[0011] As an improvement, a finger groove protruding outward is formed on the top of the knife seat, a pair of finger grooves are mirror-imaged on both sides of the knife head, and a notch matching the finger groove is formed on the top of the clamping sleeve to facilitate the removal of the knife seat.
[0012] As an improvement, a circular boss 1 is formed at the bottom of the inner brush shell, and a circular boss 2 is formed on the inner brush shell cover at a position corresponding to the circular boss 1. An inner magnet block is sandwiched and fixed between the corresponding circular boss 1 and the circular boss 2 to completely fix the position of the magnet.
[0013] As an improvement, a positioning convex ring is formed on the inner side of the outer brush shell cover, and an outer magnet block is placed inside the positioning convex ring. An iron sheet is provided on the right side of the outer magnet block, and a convex rib that contacts the iron sheet is formed on the bottom of the outer brush shell. The convex rib can increase the strength of the outer brush shell and make it less likely to deform.
[0014] The advantages of the utility model compared with the prior art are:
[0015] After frequent use, the blade can be removed from the inner brush part, inserted into the groove on the upper part of the outer brush shell and dragged back and forth, and the sharpened blade head can be used again, thereby eliminating the need to frequently replace the blade head and saving costs; at the same time, after the blade reaches the end of its service life, the knife seat can be removed by pressing the latch to quickly replace it, which is convenient to use.
