Here, the shield can be fixed in a fixed slot. With the retainer secured by the preloaded biasing member located between the retainers, the tab of the chamber contacting the tab of the retainer to move the shield and the retainer with the chamber, and further loading the biasing member.

The prior literature constituted as described above consists of a chamber installed between the bonnet and the auxiliary base, and the track is installed between the bonnet and the auxiliary base so that the screen is installed to separate cat excrement and sand. It is formed on a long outer periphery and is configured to rotate the chamber by engaging with the gear assembly of the track and the motor.

The motor and gear assembly is built into the auxiliary case, and when rotating the inclined chamber, pressure is applied by the weight of the chamber and the sand placed inside the chamber, and this pressure is transmitted to the motor, causing overload when driving. There is this.

In addition, since the load sensor installed in the auxiliary case to detect the weight of the chamber is configured to adjust its position by the elasticity of the spring, when a large load is applied, the spring loses its elasticity and does not detect the weight. There is a problem in that the chamber can be rotated continuously due to the same action as applied a lot.

In the prior art, a chamber, which is a place for a companion animal to defecate, is installed at an angle, and the chamber is rotated while the base supports it to separate the defecation.

On the other hand, in recent years, due to the development of high protein feeds and snacks for companion animals, the weight and size of companion animals are increasing, and there is a need to increase the size of the bowel processing apparatus for accommodating such companion animals.

However, the conventional method of separating excrement by rotating the chamber in an inclined state requires a configuration for stably supporting the chamber, so when the size of the chamber increases, the means of supporting the chamber must also increase in proportion to the chamber. In addition, in the existing method, the size and structure of the defecation treatment apparatus may be complicated, and power consumption may be increased to rotate the chamber. Accordingly, the development of a new defecation treatment technology that improves the existing method is required.

While the sand filter 500 rotates by the driving force of the motor 410, the opening and closing panel 330 is rotated through the rotating arm 320 of the opening and closing member 300 installed on one side of the upper drum 220 to discharge the closed The ball 222 is opened.

In Figure 12 (a) is a state in which the opening and closing panel 330 is closed with the discharge hole 222 at this time, the motor 410 and the separating net 310 are in a stopped state.

In FIG. 12 (b) shows the sand filter 500 through the shaft coupling panel 530 coupled to the rotating shaft 450 by the motor 410 is driven by receiving an electrical signal applied from the controller, the driving force of the motor 410 ) Rotates to separate the feces, the fecal treatment material with the excrement and the defecation treatment material without the excrement.

In FIG. 12 (C) is a discharge hole (C) in order to separate the excrement, the fecal treatment material containing the excrement and the defecation treatment material without the excrement by rotating the sand filter 500, and discharge the feces and the fecal treatment material 222) rotates to the formed position.

At this time, the rotating protrusion 511 formed on one side of the sand filter 500 is in close contact with one side of the rotating arm 320 so that the rotating arm 320 rotates in the same direction as the rotating arm 320.

In FIG. 12 (d), while the sand filter 500 rotates to the portion where the discharge hole 222 is located, the excrement and the fecal treatment material containing the excrement are discharged to the discharge hole 222.

At this time, since the rotating protrusion 511 formed on one side of the sand filter 500 rotates the rotary arm 320 to the upper end of the discharge hole 222, the closed discharge hole 222 is opened to open the feces and excretion treatment material It is discharged to the discharge hole 222 while being guided to the inclined separation net 510.

The excrement discharged through the discharge hole 222 and the fecal treatment material containing the excrement are separated and collected in a defecation chamber (not shown) located at one side of the upper drum 220.

In addition, when further rotation occurs in (b) of FIG. 7 and is positioned in an initial state as shown in (a), the motor 410 stops driving.

In addition, the rotation protrusion 511 formed on one side of the sand filter 500 is released in a state in close contact with the rotation arm 320, and the opening and closing panel 330 is itself in the opposite direction in which the separation net 510 rotates. The discharge hole 222 is closed while rotating in a free fall form by the weight of.

When the sand filter 500 returns to the initial state, the rotor rod 422 is positioned between the position sensor, and a signal according to the position of the rotor rod 422 is transmitted through a sensor input unit (not shown). A signal is applied to the controller, and according to the applied signal, the controller determines that the sand filter 500 is positioned in the correct position.

As described above, when the separating net 510 is positioned in the correct position (initial state, Fig. 12 (a)), the odor generated from the excreta and the defecation treatment material with excrement is discarded and collected from the discharge hole ( 222), so it is possible to prevent it from spreading to the room.

In addition, when processing cat feces, the sand filter 500 installed in the drum 200 is rotated to collect excrement placed in the fecal treatment material such as sand or wood pellets immediately after the cat exits. It can quickly remove odor from urine.

And when the cat wants to wash the drum 200 while exchanging the fecal treatment material, first, the drum 200 installed inside the lower case is separated while the upper case of the case 100 is separated, At this time, the coupling ring 440 located on one side of the reducer 411 is moved in the direction in which the cat enters and exits.

As the coupling ring 440 moves, the inner shaft 430 installed inside the rotation shaft 450 simultaneously moves, and at this time, the first coupling protrusion 442 of the coupling ring 440 is a moving hole of the rotation shaft 450 ( It moves along 453, and the second coupling protrusion 444 moves while being guided along the contact groove 454.

And when the ball (445-3) installed in the second coupling protrusion 444 by the movement of the coupling ring 440 is coupled to the ball fixing groove formed in the contact groove 454, the state of being coupled with sound is felt. Thus, the user can separate the drum 200 from the case 100.

When the user wants to attach the drum 200 to the case 100 after washing the drum 200, the assembly process is performed in the reverse order of the order for separating the drum 200 to be coupled to the case 100.

As described above, the user moves the inner shaft 430 to one side by the coupling ring 440 and separates it from the rotating body 450 without the help of an expert, so that the bowel movement such as sand or wood pellets according to the preference of the user or cat It prevents contamination of the room by the defecation treatment material because it allows the treatment material to be exchanged.

In addition, in the present invention, the drum 200 is easily separated from the case 100, so that washing with water is easy, so that the living environment of the cat is kept clean.

In addition, in the present invention, since the drum 200 is easily separated from the case 100, there is an advantage in that there are fewer civil complaints from the consumer when the parts are replaced or repaired, and the customer's satisfaction is high after the repair.
