DETAILED DESCRIPTION
[0033] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0034] See also Figure 1-7 A manual feeder includes a front cover 4, a liquid food cylinder 3 and a rear cover 2. A first recess 41 for placing a circular gasket 6 is provided on the left side of the interior of the front cover 4. The liquid food cylinder 3 is threadedly connected to the front cover 4 to form a seal through the gasket 6. The gasket 6 is provided with a second boss 61, a third boss 62 and a second recess 63, and the second boss 61 matches the first recess 41; a plunger 13 for pushing the liquid food to flow is provided inside the liquid food cylinder 3, and a first boss 14 matching the second recess 63 is provided in the middle of the left side of the plunger 13; a first platform 15 matching the third boss 62 is provided on the edge of the first boss 14. Through the above-mentioned structural setting, when the liquid food cylinder 3 is threadedly connected to the front cover 4, the sealing of the liquid food cylinder 3 and the front cover 4 is achieved, and the overflow of the liquid food or the seepage of the liquid is avoided.
[0035] A connecting tube 5 is provided on the left side of the front cover 4. The connecting tube 5 includes a first connecting tube 52 and a second connecting tube 53. The first connecting tube 52 is fixedly connected to the front cover 4. The outer diameter of the left side of the first connecting tube 52 is smaller than the outer diameter of the second connecting tube 53, and the outer diameter of the right side of the first connecting tube 52 is larger than the outer diameter of the second connecting tube 53. An anti-dropping convex plate 51 is provided on the right side of the first connecting tube 52 to prevent the feeding tube from falling off. The second connecting tube 53 is a hollow column, and the first connecting tube 52 is a hollow truncated cone. When a thin feeding tube is used to connect the feeder, it can be directly snapped onto the second connecting tube 53; when a thick feeding tube is used to connect the feeder, it can be directly snapped onto the first connecting tube 52 through the second connecting tube 53, and the thick feeding tube can be prevented from falling off by the anti-dropping convex plate 51. The first connecting tube 52 and the second connecting tube 53 can be integrally formed during manufacturing.
[0036] It should be noted that when the feeder is in use, a feeding tube needs to be connected to the connecting tube 5, and liquid food is pumped into the oral cavity or stomach through the feeding tube.
[0037] In another embodiment, the edge of the connection end between the front cover 4 and the liquid food tube 3 is provided with a second protrusion 42, and the edge of the connection end between the rear cover 2 and the liquid food tube 3 is provided with a first protrusion 22; the outer side of the cross-section of the second protrusion 42 and the first protrusion 22 is a polygon. The polygonal design of the second protrusion 42 and the first protrusion 22 prevents the feeder from rolling when placed on the table.
[0038] In another embodiment, the middle of the right side of the plunger 13 is connected to the screw push rod 11, and the middle of the right side of the rear cover 2 is provided with a cylinder 21 for the screw push rod 11 to rotate, and the inner wall of the cylinder 21 is provided with a thread matching the screw push rod 11. The right side of the screw push rod 11 is provided with a limit plate 12 and a rotating push plate 1 in sequence. By providing the limit plate 12, it can be ensured that the plunger 13 just reaches the left side inside the front cover 4, avoiding the plunger 13 from squeezing the front cover 4 and causing the front cover 4 to be sealed and damaged.
[0039] In another embodiment, the outer wall of the liquid food cylinder 3 is provided with scale lines for quantitative measurement and a groove 31 for attaching a temperature measuring strip, and anti-slip protrusions are provided on the outer sides of the front cover 4 and the rear cover 2. The scale lines can be used to observe the feeding amount, and the temperature measuring strip can be attached to the groove 31 to display the temperature of the liquid food to avoid the influence of the liquid food temperature being too high or too low on the patient. The provision of the anti-slip protrusion facilitates the connection between the front cover 4, the rear cover 2 and the liquid food cylinder 3, and avoids the hand slipping during the connection.
[0040] In another embodiment, referring to Figure 8 The cross-section of the rotating push plate 1 is an irregular circle, and a grip 16 is provided on the side of the rotating push plate 1 (the grip 16 is threadedly connected to the rotating push plate 1). When eating some liquid food with high viscosity, it is quite strenuous to rotate the push plate 1 only by five fingers of one hand. By holding the grip 16, more force can be used to rotate the rotating push plate 1, so as to achieve the eating of liquid food with high viscosity.
[0041] like Figure 1 , Figure 4 , Figure 7 As shown, when the manual feeder is used, the gasket 6 is placed in the first recess 41 of the front cover 4, and the front cover 4 is threadedly connected to the liquid food tube 3; the spiral push rod 11 spirally passes through the rear cover 2, and the plunger 13 is connected to the spiral push rod 11, and the right side of the spiral push rod 11 is connected to the rotating push plate 1 (the spiral push rod 11 and the rotating push plate 1 can be integrally formed or snap-connected); the plunger 13 and the spiral push rod 11 are inserted into the liquid food tube 3, and the liquid food tube 3 is threadedly connected to the rear cover 2 to realize the assembly of the manual feeder.
[0042] There are two ways to add liquid food to a manual feeder. The first is to put the manual feeder in the initial state (such as Figure 1 , 2 As shown in the figure), the connecting tube 5 is inserted into the liquid food, and the rotating push plate 1 is rotated counterclockwise, and the rotating push plate 1 drives the spiral push rod 11 to rotate and move right, and the rightward movement of the spiral push rod 11 drives the plunger 13 to move right, so that the liquid food barrel 3 forms a negative pressure space to suck the liquid food; the second way is to rotate and disassemble the liquid food barrel 3 and the rear cover 2, pull out the plunger 13 and the spiral push rod 11, pour the liquid food into the liquid food barrel 3, and then insert the plunger 13 and the spiral push rod 11 into the liquid food barrel 3, and tighten the liquid food barrel 3 and the rear cover 2 to realize the loading of the liquid food.
[0043] During feeding, the connecting tube 5 is connected to the feeding tube, and the rotating push plate 1 is rotated clockwise. The rotation of the rotating push plate 1 drives the spiral push rod 11 to rotate and move leftward. The leftward movement of the spiral push rod 11 drives the plunger 13 to move leftward, thereby realizing the extrusion of liquid food.
[0044] When eating liquid food with high viscosity, the grip rod 16 is threadedly connected to the rotating push plate 1. By holding the grip rod 16 and the rotating push plate 1 with one hand, greater force can be used to rotate the rotating push plate 1, so as to eat liquid food with high viscosity.
[0045] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
