TECHNICAL FIELD

[0001] The utility model relates to the field of expansion water kettle, especially to reduce the expansion water kettle of scale accumulation. BACKGROUND

[0002] The expansion water kettle is a container for storing coolant in the automobile.

[0003] The Chinese patent with the application number 202022475926.X discloses a self-locking anti-loosening structure of a filling opening sealing cover of an automobile expansion water kettle, which comprises an automobile expansion water kettle body, a drain pipe communicated with the bottom of the right side of the automobile expansion water kettle body, a fixed plate fixedly connected with the top of the two sides of the automobile expansion water kettle body, a water filling pipe communicated with the right side of the top of the automobile expansion water kettle body, and a sealing cover threadedly connected in the water filling pipe.

[0004] The above-mentioned expansion water kettle will accumulate scale on the inner wall during long-term use, and the continuously stacked scale will reduce the volume of the expansion water kettle, hinder the flow of coolant, and even block various connecting pipelines. UTILITY MODEL CONTENTS

[0005] The utility model provides an expansion water kettle capable of reducing scale accumulation in view of the problem that the inner wall of the expansion water kettle will accumulate scale during long-term use in the prior art, which affects the use of the expansion water kettle.

[0006] In order to solve the above-mentioned technical problem, the utility model solves the problem through the following technical scheme:

[0007] The utility model provides an expansion water kettle capable of reducing scale accumulation, which comprises a kettle body, a scale removal structure for reducing scale accumulation arranged in the kettle body, the scale removal structure comprising a scraper arranged along the length direction of the kettle body and a driving structure for driving the scraper to rotate and scrape the scale on the inner wall of the kettle body.

[0008] The driving structure drives the scraper to rotate around the length direction of the kettle body, and the scraper is always attached to the inner wall of the kettle body during rotation, so that the scale accumulated on the inner wall of the kettle body is scraped off, and the scraped scale is discharged from the kettle body, thereby reducing the accumulation of scale in the kettle body.

[0009] Preferably, the driving structure comprises a rotating shaft arranged along the length direction of the kettle body and sealingly connected to the side wall of the kettle body, one end of the rotating shaft is located outside the kettle body, and the other end is inserted into the kettle body, and the scraper is arranged on the end of the rotating shaft located inside the kettle body.

[0010] The above-mentioned scheme can drive the scraper to rotate by rotating the end of the rotating shaft located outside the kettle body, so that the scale can be scraped off.

[0011] Preferably, an elastic adjusting structure is arranged between the rotating shaft and the scraper to control the elastic extension and contraction of the scraper along the vertical direction of the length of the kettle body when the rotating shaft rotates, so as to ensure that the scraper is in elastic abutment with the inner wall of the kettle body when the rotating shaft rotates, thereby scraping off the scale.

[0012] In actual application, the kettle body is not a regular cylinder, and therefore, the elastic adjusting structure is arranged between the rotating shaft and the scraper to enable the scraper to elastically extend and contract along the vertical direction of the length of the kettle body, so as to ensure the smooth rotation of the scraper in the kettle body and enable the scraper to abut against the inner wall of the kettle body during rotation to scrape off the scale.

[0013] Preferably, the elastic adjusting structure comprises a fixed rod arranged on the end of the rotating shaft away from the handle and perpendicular to the rotating shaft, and an extension rod arranged on the end of the fixed rod close to the scraper to elastically extend and contract along the length direction of the fixed rod, and the end of the extension rod away from the fixed rod is fixedly connected with the scraper.

[0014] When the rotating shaft rotates, the fixed rod, the extension rod and the scraper rotate synchronously. During the rotation of the scraper, if the distance between the inner wall of the kettle body and the end of the fixed rod where the extension rod is arranged decreases, the inner wall of the kettle body and the scraper are in extrusion and sliding cooperation, and the scraper and the extension rod are elastically retracted while the scale is scraped off; if the distance between the inner wall of the kettle body and the end of the fixed rod where the extension rod is arranged increases, the scraper and the extension rod elastically extend to abut against the inner wall of the kettle body.

[0015] Preferably, the scraper is provided with an auxiliary cleaning structure for scraping off the scale remaining on the scraper.

[0016] In the long-term use and after the scraper scrapes off the scale, part of the scale will accumulate or adhere to the scraper, and the auxiliary cleaning structure is arranged to clean the scraper.

[0017] Preferably, the auxiliary cleaning structure comprises a wiping plate arranged on the side walls of the scraper to slide along the length direction of the scraper to scrape off the scale on the two sides of the scraper, and a connecting scraping strip arranged between the two wiping plates to connect the two wiping plates and scrape off the scale on the side of the scraper away from the abutment with the inner wall of the kettle body, and the wiping plate and the connecting scraping strip are made of a metal material that can be magnetically attracted.

[0018] In the above scheme, the operator moves the magnet outside the kettle body, and the wiping plate and the connecting scraping strip are driven to slide along the length direction of the scraper by the magnetic attraction force of the magnet, so as to scrape off the scale adhering to the scraper, thereby achieving the cleaning of the scraper.

[0019] Preferably, a handle is arranged on the end of the rotating shaft outside the kettle body to facilitate the rotation of the rotating shaft.

[0020] In the above scheme, the handle is arranged to increase the force application point and facilitate the rotation of the rotating shaft.

[0021] The utility model discloses a kind of expansion water jugs of reducing scale accumulation, comprising: kettle body, scraper, rotating shaft, elastic adjusting structure and auxiliary cleaning structure, the kettle body is provided with liquid inlet and liquid outlet, the scraper is arranged in kettle body, the rotating shaft is arranged in kettle body, the elastic adjusting structure is arranged on the rotating shaft, and the auxiliary cleaning structure is arranged on the rotating shaft.
