VACUUM TYPE AUTOMATIC SUPPLYING APPARATUS OF PET FOOD

The present invention relates to a vacuum-type automatic feed supplying device, and more specifically, by maintaining the entire main body of the automatic feed feeding device in a vacuum state as well as the feed storage hopper for storing feed, moisture contained in the air inside the feed storage hopper is reduced Of course, by removing harmful microorganisms or bacteria, the feed is always kept fresh and clean, preventing indoor air contamination and protecting the dog's health, as well as protecting the dog's health. A sealing packing is installed on the inner circumferential surface to increase the vacuum level by preventing external air from entering through the gap between the feed supply hole and the feed supply hole blocking cover when the inside of the automatic feed supply device body is maintained in a vacuum state. It relates to a vacuum-type automatic feeding device that can.

In general, pets (愛玩物) refer to animals that humans raise mainly for pleasure. Today, they are sometimes called companion animals (伴侶animal) in the sense of treating them as companions (friends) rather than simply human toys.

In order to keep pets healthy, special affection and management are essential. In particular, if proper quantity and clean feed or snacks are not supplied in a timely manner, nutritional deficiencies, obesity, or overeating problems may occur. is required

However, in the case of busy modern people, it is very cumbersome to provide pets with a fixed amount of food and snacks at set times every day. Feeding problems for pets left alone are also serious.

Accordingly, there are cases where a large amount of feed is provided to the pet at once and then goes out. If a large amount of feed is provided at once in this way, the pet will eat a lot of food at once, which may cause a problem due to overeating. , especially during the monsoon season, as the feed becomes soggy or easily spoiled due to moisture, there is a problem that not only the health of the pet can occur, but also an unpleasant odor is generated in the house due to a large amount of food exposed to the air.

In order to solve this problem, in the related art, an automatic feeder for pet food that stores feed inside the feeder and automatically supplies a fixed amount of feed at a predetermined time is disclosed in Korean Patent Application Laid-Open No. 10-2009-80836 (published date: 2009.07.27) has been proposed.

However, in the conventional automatic feeder for pet food as described above, air is included with the feed in the feed storage bin, and the air contains not only moisture but also harmful microorganisms and bacteria, which makes the feed moist. There is a problem that pollutes the indoor air by spoiling the feed, and harms the health of the dog.

In addition, when the feed storage bin is not completely sealed, impurities as well as air may be inserted into the inside during the storage process, and there is a problem in that the feed is damaged or decayed by the inserted air or impurities.
