According to the data, the data of dogs and cats kept in our country reach more than eight thousand, so that the pet keeping has become a mainstream, along with the large working pressure, the demand of people for carrying emotion is also met, and people are more and more enjoyable by the pet keeping. However, since pets which do not feed loved ones on time at ordinary times, overtime, or frequently go out to worry about loving one's diet, or go out to travel and leave on the pet regardless of trouble, pet feeders have been developed to solve the above problems.
The existing pet feeders generally have a grain storage bin 1 for storing pet grains, and the pet grains in the grain storage bin 1 are rotated to a grain outlet channel by a driving screw. Wherein, the screw rod of hard material extrudees each other with other parts when the pay-off, leads to pet grain granule to be crushed, and over time, garrulous powder is driven to between a plurality of parts, makes the screw rod rotate no longer smooth and easy, appears blocking up the condition of grain outlet 11, has the improvement.
In view of the above, the embodiment of the utility model discloses a pet feeder capable of preventing food from being blocked, and the buffer area 23 is arranged on the feeding screw 2, so that the pet feeder can be prevented from being blocked, and can run more stably.
The pet feeder comprises a grain storage bin 1, wherein an inclined hopper 3 is arranged in the grain storage bin 1, a grain delivery channel 31 is formed between the inner bottom surface of the grain storage bin 1 and the inclined hopper 3, and a grain outlet 11 is formed in the grain delivery channel 31. In some embodiments, the grain bin 1 is in the shape of a quadrangular prism, such as a cuboid or cube.
The pet feeder further comprises a feeding screw 2, wherein the feeding screw 2 is used for conveying pet food to the food outlet 11, the feeding screw 2 comprises a feeding roller 21 and a helical blade 22 fixedly connected to the circumferential outer side of the feeding roller 21, and the feeding screw 2 is at least partially positioned in the food delivery channel 31.
The pet feeder also comprises at least one buffer area 23, wherein the buffer area 23 is arranged on the feeding screw 2 positioned outside the grain feeding channel 31, and the buffer area 23 is arranged at a position close to the inlet of the grain feeding channel 31; the outer diameter of the helical blade 22 in the cushioned region 23 is smaller than the outer diameter of the helical blade 22 in the unbuffered region 24.
According to the embodiment, the buffer area 23 is arranged on the feeding screw 2, and the buffer area 23 is arranged at a position close to the inlet of the grain feeding channel 31, wherein the outer diameter of the helical blade 22 of the buffer area 23 is smaller than that of the helical blade 22 in the non-buffer area 24, when the feeding screw 2 rotates to feed, pet grain particles have two different travelling paths in the buffer area 23, firstly, the pet grain particles can continue to move along the axial direction of the feeding screw 2 until the grain outlet 11, secondly, the pet grain particles can be extruded upwards, fall back to the non-buffer area which is originally travelled, and travel towards the grain outlet 11, so that circulation is formed. Therefore, when the feeding path 31 is blocked or stuck, even if the feeding screw 2 continues to rotate, the blocking is not further aggravated.
Referring to fig. 1-5, in one embodiment, the buffer zone 23 extends onto the feed screw 2 within the feed channel 31. In a further embodiment, the buffer zone 23 extends to the end of the feed screw 2 near the grain outlet 11. Thus, the position of the buffer area 23 on the feeding screw 2 can be arranged not only outside the grain feeding channel 31 but also inside the grain feeding channel 31; in addition, the feeding screw 2 in the grain feeding channel 31 can be all arranged as a buffer area 23, so that the overall grain blocking preventing performance is further improved, or one part of the feeding screw can be arranged as the buffer area 23, and the other part of the feeding screw is a non-buffer area 24, so that the grain blocking preventing performance can be improved, and the sufficient feeding performance can be ensured.
Referring to fig. 1-5, in an embodiment, a plurality of buffer areas 23 are provided, and the plurality of buffer areas 23 are disposed at intervals along the axial direction of the feeding screw 2, so that the plurality of buffer areas 23 can make pet grain particles fall back to the original travelling non-buffer area for many times, and then travel towards the grain outlet 11, forming a cycle, and further improving the overall grain blocking preventing performance.

For a more visual understanding, reference can be made to fig. 5, the length of the buffer zone 23 in the axial direction of the feed screw 2 is H1, and the overall length of the feed screw 2 is H2.
Therefore, through multiple experiments, when the ratio is at least 1/3, the anti-jamming grain structure is enough to play a role in preventing the jamming grain, and the feeding capacity is not excessively reduced, so that the pet feeder can feed normally.
Referring to FIGS. 1-5, in one embodiment, the ratio of the outer diameter of the helical blade 22 in the cushioned region 23 to the outer diameter of the helical blade 22 in the unbuffered region 24 is less than 2/3, e.g., 2/3, 1/2, or 1/3, although in other embodiments the ratio may be other values within this range. It should be noted that since the feeding screw 2 is required to feed pet food, the ratio is required to be greater than 0. For a more visual understanding, reference may be made to FIG. 5, where the outside diameter of the helical blade 22 in the cushioned region 23 is D1 and the outside diameter of the helical blade 22 in the unbuffered region 24 is D2. Therefore, through multiple experiments, when the ratio is at least 2/3, the anti-jamming grain structure is enough to play a role in preventing the jamming grain, and the feeding capacity is not excessively reduced, so that the pet feeder can feed normally.

Like this, through setting up the interior bottom surface of storing up granary 1 and forming the inclined plane of upward slope, the feeding screw rod 2 that the cooperation upward slope set up can carry pet grain to the grain outlet 11 with the pet grain in the storing up granary 1 from bottom to top, because pet grain itself can receive gravity, can not once only spit more grain under the effect of self gravity when upwards slope carries pet grain to grain outlet 11, can control the play grain volume of pet grain better.
Referring to fig. 1-5, in one embodiment, the height dimension of the feed channel 31 decreases from one end of the feed channel 31 itself near the outlet 11 to the other end remote from the outlet 11. Because in the actual process of conveying pet food, the pet food can be piled up in the feeding channel 31, in order to avoid excessive pressure generated by excessive pet food, the height dimension of one end of the feeding channel 31 close to the grain outlet 11 is larger than that of the other end of the feeding channel 31 far away from the grain outlet 11, a funnel-shaped or trapezoid-like structure is formed, which is equivalent to forming a flat pressing cavity in the feeding channel 31, and the pressure of other pet food in the grain storage 1 at the inlet of the feeding channel 31 is balanced, so that the pet food conveyed to the grain outlet 11 by the feeding screw 2 is more uniform.
Referring to fig. 1-5, in one embodiment, the pet food dispensing device further comprises a power assembly comprising a motor 4, wherein the output end of the motor 4 is connected to the feed screw 2. In one embodiment, a power input hole 12 is formed in one side surface of the grain bin 1, which is close to the lower side of the inner bottom surface, and one end of the feeding screw 2 penetrates through the power input hole 12 to be connected with the output end of the motor 4. In this way, the motor 4 is used for driving the feeding screw rod 2 to rotate unidirectionally in the correct direction, and the motor 4 can be used for controlling the rotation number of the feeding screw rod 2, so as to control the discharge amount of pet food; or, the timing and quantitative discharging of the pet food can be realized through the motor 4.
