DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1

[0028] The present invention provides a technical solution: a scale scraping device for Chinese medicine cooking equipment, comprising a box body 1 and a resistance heating element 5, a filter plate 11 is fixedly connected to the inner wall of the box body 1, the box body 1 is divided into a cooking chamber 14 and a heating chamber 15 by the filter plate 11, a rotating shaft 2 is fixedly connected to the inner wall of the heating chamber 15 for rotation, one end of the rotating shaft 2 extending out of the heating chamber 15 is fixedly connected to an external power source, a first gear 21 is fixedly connected to the rotating shaft 2, a first rotating rod 22 is fixedly connected to the inner wall of the heating chamber 15 for rotation, a second gear 23 meshing with the first gear 21 is fixedly connected to the first rotating rod 22, a preliminary scraping mechanism for scraping scale off the arc contour of the resistance heating element 5 is provided on the second gear 23, and a secondary scraping mechanism for scraping scale off the head of the resistance heating element 5 is provided on the rotating shaft 2.

[0029] When in use, the filter plate 11 is provided to prevent scale in the heating chamber 15 from flowing into the cooking chamber 14, thereby affecting the cooking of the Chinese medicine, and then the external power source is started.

[0030] The external power source may be a motor, which is not shown in the figure because it is an existing device. When using it, a suitable motor may be selected according to the actual usage.

[0031] Furthermore, the preliminary scraping mechanism includes a sleeve 3 fixedly connected to the second gear 23, a cylindrical cam 31 is slidably connected to the inner wall of the sleeve 3, a slider 32 is fixedly connected to the inner wall of the sleeve 3, and a sliding groove is provided on the cylindrical cam 31 and is slidably connected to the slider 32 through the sliding groove.

[0032] Furthermore, the preliminary scraping mechanism also includes a support plate 7 and a support rod 71. A slide groove is provided on the upper surface of the cylindrical cam 31 and is slidingly connected to the support plate 7 through the slide groove. The support plate 7 is fixedly connected to the support rod 71. The support rod 71 is rotatably connected with a first scraper 72 and a second scraper 73 for scraping scale for the resistance heating element 5.

[0033] Furthermore, the preliminary scraping mechanism also includes a limiting rod 12 fixedly connected to the heating chamber 15 , and limiting grooves cooperating with the limiting rod 12 are provided on the cylindrical cam 31 and the support plate 7 .

[0034] Furthermore, the limiting rod 12 is in a rectangular shape.

[0035] After the external power source is started, the rotating shaft 2 rotates, thereby rotating the first gear 21 thereon, and since the second gear 23 is meshed with the first gear 21, the second gear 23 rotates synchronously, thereby rotating the first rotating rod 22 and the sleeve 3 synchronously.

[0036] When the sleeve 3 rotates, the slider 32 on its inner wall rotates synchronously. Since the sliding groove on the cylindrical cam 31 is slidably connected to the slider 32, and the cylindrical cam 31 and the support plate 7 are both provided with limiting grooves that cooperate with the limiting rod 12, and the limiting rod 12 is rectangular, the cylindrical cam 31 slides back and forth along the inner wall of the sleeve 3.

[0037] When the cylindrical cam 31 slides toward one end of the rack 13, the support plate 7 thereon slides toward one end of the rack 13 synchronously, so that the support rod 71 drives the first scraper 72 and the second scraper 73 to slide toward one end of the rack 13 synchronously, so that the first scraper 72 and the second scraper 73 can scrape the scale on the arc-shaped contour of the resistance heating element 5.

[0038] Furthermore, the secondary scraping mechanism includes a cam 24 fixedly connected to the rotating shaft 2 and cooperating with the first scraper 72 and the second scraper 73. The first scraper 72 and the second scraper 73 are both fixedly connected with pins, and the two pins are fixedly connected with springs 74.

[0039] When the cylindrical cam 31 drives the first scraper 72 and the second scraper 73 to slide toward one end of the rack 13 to the head of the resistance heating element 5, at this time, the cam 24 contacts the first scraper 72 and the second scraper 73, and then when the first scraper 72 and the second scraper 73 continue to slide toward one end of the rack 13, the first scraper 72 and the second scraper 73 rotate with the support rod 71 as the center, so that the heads of the first scraper 72 and the second scraper 73 gradually approach each other, so that the first scraper 72 and the second scraper 73 scrape the head of the resistance heating element 5, so that the scale on the head of the resistance heating element 5 is scraped off.

[0040] By setting up the primary scraping mechanism and the secondary scraping mechanism, the scale on the resistance heating element 5 can be scraped off, and the scale is prevented from being adsorbed on the resistance heating element 5 and accumulating over time to act as a thermal insulator. At this time, the insulated resistance heating element 5 becomes hotter, which wastes energy and eventually burns out the resistance heating element 5 during operation. When scale is adsorbed on the resistance heating element 5, the outer shell of the resistance heating element 5 is heated first, and then the scale on the surface of the outer shell of the resistance heating element 5 is heated, and finally the liquid is heated. Therefore, the delay effect when heating the liquid is avoided at the same time.

[0041] Embodiment 2

[0042] Basically the same as the first embodiment, further, a moving mechanism is provided on the rotating shaft 2 for moving the first scraper 72 and the second scraper 73 after scraping, and the moving mechanism includes a disc 4 fixedly connected to the rotating shaft 2, a D-shaped groove is provided on the disc 4 and a telescopic rod 41 is connected to the disc 4 through a limited sliding connection through the D-shaped groove, and the end of the telescopic rod 41 away from the disc 4 is fixedly connected to the support plate 7.

[0043] When the first scraper 72 and the second scraper 73 finish scraping the head of the resistance heating element 5, at this time, the cylindrical cam 31 continues to slide toward one end of the rack 13, and at this time the cam 24 cancels contact with the first scraper 72 and the second scraper 73, so that the elastic force of the spring 74 is released, so that the first scraper 72 and the second scraper 73 are reset.

[0044] When the first scraper 72 and the second scraper 73 have finished scraping the head of the resistance heating element 5, at the same time, the telescopic rod 41 slides along the D-shaped groove of the disk 4 to complete the semicircular groove and slides to the straight groove, so that the telescopic rod 41 slides toward one end of the cam 24, and the support plate 7 drives the first scraper 72 and the second scraper 73 to slide toward one end of the cam 24 synchronously, so that the heads of the first scraper 72 and the second scraper 73 are away from the resistance heating element 5 and slide to the vicinity of the cleaning head 61, thereby achieving the effect of facilitating the cleaning of the first scraper 72 and the second scraper 73 and avoiding damage to the resistance heating element 5 when cleaning the first scraper 72 and the second scraper 73.

[0045] By providing the telescopic rod 41 , when the support plate 7 slides in the direction of the rack 13 , the telescopic rod 41 is telescoped synchronously, thereby avoiding interference.

[0046] The telescopic rod 41 is an existing mechanism, and the related technology is relatively mature and well known to those skilled in the art, so it will not be publicly described here.

[0047] Embodiment 3

[0048] Basically the same as the second embodiment, further, a cleaning mechanism for cleaning scale on the first scraper 72 and the second scraper 73 is provided on the cylindrical cam 31, and the cleaning mechanism includes a connecting rod 33 fixedly connected to the cylindrical cam 31, a through hole is opened on the connecting rod 33 and a second rotating rod 34 is connected to the connecting rod 33 for fixed axis rotation through the through hole, and a cleaning head 61 for cleaning scale on the first scraper 72 and the second scraper 73 is fixedly connected to the second rotating rod 34.

[0049] Furthermore, the cleaning mechanism also includes a rack 13 fixedly connected to the inner wall of the heating chamber 15 , and one end of the second rotating rod 34 away from the cleaning head 61 is fixedly connected to a third gear 6 intermittently meshing with the rack 13 .

[0050] When the heads of the first scraper 72 and the second scraper 73 slide to the vicinity of the cleaning head 61, at the same time, the cylindrical cam 31 drives the connecting rod 33 to slide synchronously toward one end of the rack 13, so that the third gear 6 engages with the rack 13, so that the cleaning head 61 rotates to remove the scale on the heads of the first scraper 72 and the second scraper 73, thereby avoiding the effect that the scale on the first scraper 72 and the second scraper 73 adheres to the resistance heating element 5 when they clean the resistance heating element 5 next time.

[0051] Working principle: When in use, the scale scraping device of the Chinese medicine cooking equipment prevents the scale in the heating chamber 15 from flowing into the cooking chamber 14 by setting the filter plate 11, thereby preventing the scale from affecting the cooking of the Chinese medicine, and then starting the external power source.

[0052] The external power source may be a motor, which is not shown in the figure because it is an existing device. When using it, a suitable motor may be selected according to the actual usage.

[0053] After the external power source is started, the rotating shaft 2 rotates, thereby rotating the first gear 21 thereon, and since the second gear 23 is meshed with the first gear 21, the second gear 23 rotates synchronously, thereby rotating the first rotating rod 22 and the sleeve 3 synchronously.

[0054] When the sleeve 3 rotates, the slider 32 on its inner wall rotates synchronously. Since the sliding groove on the cylindrical cam 31 is slidably connected to the slider 32, and the cylindrical cam 31 and the support plate 7 are both provided with limiting grooves that cooperate with the limiting rod 12, and the limiting rod 12 is rectangular, the cylindrical cam 31 slides back and forth along the inner wall of the sleeve 3.

[0055] When the cylindrical cam 31 slides toward one end of the rack 13, the support plate 7 thereon slides toward one end of the rack 13 synchronously, so that the support rod 71 drives the first scraper 72 and the second scraper 73 to slide toward one end of the rack 13 synchronously, so that the first scraper 72 and the second scraper 73 can scrape the scale on the arc-shaped contour of the resistance heating element 5.

[0056] When the cylindrical cam 31 drives the first scraper 72 and the second scraper 73 to slide toward one end of the rack 13 to the head of the resistance heating element 5, at this time, the cam 24 contacts the first scraper 72 and the second scraper 73, and then when the first scraper 72 and the second scraper 73 continue to slide toward one end of the rack 13, the first scraper 72 and the second scraper 73 rotate with the support rod 71 as the center, so that the heads of the first scraper 72 and the second scraper 73 gradually approach each other, so that the first scraper 72 and the second scraper 73 scrape the head of the resistance heating element 5, so that the scale on the head of the resistance heating element 5 is scraped off.

[0057] By setting up the primary scraping mechanism and the secondary scraping mechanism, the scale on the resistance heating element 5 can be scraped off, and the scale is prevented from being adsorbed on the resistance heating element 5 and accumulating over time to act as a thermal insulator. At this time, the insulated resistance heating element 5 becomes hotter, which wastes energy and eventually burns out the resistance heating element 5 during operation. When scale is adsorbed on the resistance heating element 5, the outer shell of the resistance heating element 5 is heated first, and then the scale on the surface of the outer shell of the resistance heating element 5 is heated, and finally the liquid is heated. Therefore, the delay effect when heating the liquid is avoided at the same time.

[0058] When the first scraper 72 and the second scraper 73 finish scraping the head of the resistance heating element 5, at this time, the cylindrical cam 31 continues to slide toward one end of the rack 13, and at this time the cam 24 cancels contact with the first scraper 72 and the second scraper 73, so that the elastic force of the spring 74 is released, so that the first scraper 72 and the second scraper 73 are reset.

[0059] When the first scraper 72 and the second scraper 73 have finished scraping the head of the resistance heating element 5, at the same time, the telescopic rod 41 slides along the D-shaped groove of the disk 4 to complete the semicircular groove and slides to the straight groove, so that the telescopic rod 41 slides toward one end of the cam 24, and the support plate 7 drives the first scraper 72 and the second scraper 73 to slide toward one end of the cam 24 synchronously, so that the heads of the first scraper 72 and the second scraper 73 are away from the resistance heating element 5 and slide to the vicinity of the cleaning head 61, thereby achieving the effect of facilitating the cleaning of the first scraper 72 and the second scraper 73 and avoiding damage to the resistance heating element 5 when cleaning the first scraper 72 and the second scraper 73.

[0060] By providing the telescopic rod 41 , when the support plate 7 slides in the direction of the rack 13 , the telescopic rod 41 is telescoped synchronously, thereby avoiding interference.

[0061] The telescopic rod 41 is an existing mechanism, and the related technology is relatively mature and well known to those skilled in the art, so it will not be publicly described here.

[0062] When the heads of the first scraper 72 and the second scraper 73 slide to the vicinity of the cleaning head 61, at the same time, the cylindrical cam 31 drives the connecting rod 33 to slide synchronously toward one end of the rack 13, so that the third gear 6 engages with the rack 13, so that the cleaning head 61 rotates to remove the scale on the heads of the first scraper 72 and the second scraper 73, thereby avoiding the effect that the scale on the first scraper 72 and the second scraper 73 adheres to the resistance heating element 5 when they clean the resistance heating element 5 next time.

[0063] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
