Full-automatic pet toilet

Abstract

The invention discloses a full-automatic pet toilet. The full-automatic pet toilet comprises a roller and an upper machine body assembly. The front end of the roller is provided with an inlet for a pet to enter, and the rear end is provided with a protruding coupling key; the upper machine body assembly comprises an upper machine body and a transmission gear, the upper surface of the upper machine body assembly is in a concave spherical shape, and a gear bin is arranged at the rear end of the upper machine body assembly. The transmission gear comprises a gear body and a gear shaft located in the center of the gear body, and an X-shaped groove is formed in the end face of the gear shaft in the axis direction of the gear shaft in an inwards-concave mode. The size of the narrowest part of the X-shaped groove is larger than the width of the coupling key, and the coupling key is embedded in the X-shaped groove and can rotate left and right. When the full-automatic pet toilet is used and the roller is in an initial state, the coupling key does not make contact with the X-shaped groove, only four supporting wheels on the upper machine body assembly make contact with the roller, the gravity borne by the roller can be directly transmitted to the weighing strain gauge, and therefore the function that the whole machine accurately weighs objects in the roller is achieved.

Description

technical field [0001] The present application relates to the technical field of pet toilets, in particular to a fully automatic pet toilet. Background technique [0002] The existing roller rotary separation pet toilets on the market can complete the collection of pet feces, and the separation mechanism is a rotating ball or a rotating bucket with gears on the surface of the barrel. But in the process of cleaning up pet excrement, collecting pet excrement is only a small part. The entire cleaning of pet waste includes: adding pet scented sand, filling garbage bags, collecting pet waste, packing garbage packages, replenishing garbage bags, taking away garbage packages, replenishing pet scented sand, cleaning up spilled pet scented sand, etc. [0003] Due to the centralized collection of pet feces in the rotary separation type pet toilet, and the garbage bags are not closed, users have to endure the stench of a large amount of pet feces accumulated for a long time and bear t...

Problems solved by technology

However, the following problems exist under the current technical conditions: 1. Installing the load cell at the bottom of the whole machine will increase the failure rate of the load cell; It is related to the measurement range, so the error will become larger; 3. Setting the load cell under the roller separation mechanism will make the structure very complicated and increase the product cost; most of the transmission gears of pet toilets are currently designed on the roller separation mechanism, and at the same time The user needs to take out the drum for cleaning, so the power output gear used to drive the drum separation mechanism is often placed under the gear of the lower drum, which will cause some scattered pet scented sand to fall from the opening of the structure when the user adds pet scented sand. Inside the machine, causing machine failure or cleaning difficulties
