Vacuum type automatic feeding device {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 pollution, protecting the dog's health, and the feed supply hole formed in the front of the automatic feed supply device body. A sealing packing is installed on the inner circumferential surface to prevent 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, thereby increasing the vacuum level. 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animals) 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 a fixed amount of food and snacks to pets at set times every day, and if the whole family goes out or travels without a pet due to unavoidable circumstances, 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 or , especially in the rainy 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 Publication 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 moisture as well as harmful microorganisms or bacteria are included in the air to make the feed moist as well as the like. There is a problem of decomposing feed, polluting indoor air, and harming the health of dogs.

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

Domestic Registered Patent No. 10-1321953

In order to solve the above problems, the present invention maintains the entire main body of the automatic feed supply device as well as the feed storage hopper for storing the feed in a vacuum state, so that moisture contained in the air inside the feed storage hopper, as well as harmful microorganisms or bacteria, etc. By removing the , it is an object to provide a vacuum-type automatic feeder that can always keep the feed fresh and clean to prevent contamination of the indoor air, and protect the health of the dog.

In addition, the present invention provides a vacuum-type automatic feed supply device capable of blocking the ingress of impurities or spoilage of feed by completely sealing the space in which the feed formed inside the body is stored by controlling the sealing structure between the main body and the cover of the self-supplying device. The purpose is to provide.

In order to achieve the above object, the vacuum feed automatic feeder of the present invention is a vacuum feed automatic feeder that maintains the inside in a vacuum state,

an automatic feed supplying device main body formed so as to maintain a space in a vacuum state therein, a feed supply hole formed in the front, and a cover installed on the top to be able to be opened and closed; a feed storage hopper that is installed in the space and stores feed therein; a feed supply unit for selectively opening the feed supply hole 12 to supply the dog feed guided by the feed discharge guide duct; and a feed discharging guide duct extending under the feed storage hopper and having a feed discharging hole for discharging feed, wherein a first weather strip is installed on the edge of the cover of the automatic feeder body, the A second weather strip is installed on the upper edge of the automatic feeder body, and when the automatic feeder body is vacuumed inside, the second weather strip surrounds the upper surface of the first weather strip by vacuum pressure.

In addition, the second weather strip includes a fitting portion fixed to the rim of the cover, and a contact portion extending from one side of the fitting portion and contacting an outer surface of the first weather strip, and During internal vacuum, the contact portion surrounds the upper surface of the first weather strip by vacuum pressure.

In addition, the second weather strip is formed to extend from the other side of the fitting portion and is formed to be relatively longer than the contact portion to further include a contact portion surrounding the contact portion, and when the internal vacuum of the automatic supply device body is internally vacuumed, the The contact part wraps the outer surface of the contact part to seal the inside of the automatic feeder body.

As described above, the present invention maintains the entire body of the automatic feed supply device as well as the feed storage hopper for storing the feed in a vacuum state to remove moisture contained in the air inside the feed storage hopper, as well as harmful microorganisms or bacteria. By doing so, the feed is always kept fresh and clean to prevent contamination of the indoor air, and there is an effect that can protect the health of the dog.

In addition, the present invention adjusts the sealing structure between the main body and the cover of the self-supplying device, and by completely sealing the space in which the feed formed inside the body is stored, it is possible to block the spoilage of the feed or the inflow of impurities, and thereby for a longer period of time Feed can be stored, so feed cost can also be reduced.
