Description

Technical Field

[0001] This utility model relates to the technical field of pet supplies, and in particular to a pet feces treatment device. Background Technology

[0002] With the development of the industry, pet toilets on the market generally come equipped with waste disposal devices, eliminating the need for owners to manually handle pet waste. Existing waste disposal devices, such as the Chinese utility model patent with publication number CN219377350U entitled "Tail Disposal Device," include a collection and grinding chamber and a grinding wheel. The collection and grinding chamber is divided into a collection chamber arranged vertically and a grinding chamber, with the grinding wheel rotatably positioned within the grinding chamber, its axis of rotation vertically aligned. During operation, the ground fecal matter mixes with water, increasing the contact area between odorous substances and air, causing existing waste disposal devices to emit a strong odor into the environment. Utility Model Content

[0003] The purpose of this utility model is to provide a pet feces treatment device, which has the advantages of simple structure, reasonable design and little odor during operation.

[0004] The technical solution adopted by this utility model is: a pet feces treatment device, including a collection chamber, an anode conductor, a cathode conductor and a DC power supply. The collection chamber has an upper opening collection cavity. The anode conductor and the cathode conductor are disposed in the collection cavity. The anode output terminal of the DC power supply is connected to the anode conductor and the cathode output terminal of the DC power supply is connected to the cathode conductor.

[0005] The working principle of this utility model:

[0006] During use, feces and litter blocks are transported to the collection chamber of the collection compartment for collection. Tap water is then injected into the collection chamber, and the tap water comes into contact with the anode and cathode conductors. Under automatic or manual control, a DC power supply energizes the anode and cathode conductors, causing an electrolytic reaction in the water within the collection chamber. Because tap water contains residual chlorine, and some pet litter components contain small amounts of chloride salts, the mixture of feces and litter blocks and tap water generates hypochlorous acid during the electrolytic reaction. Hypochlorous acid reacts chemically with odor-causing substances in the water to achieve deodorization, resulting in less odor emitted by this pet feces treatment device. Furthermore, hypochlorous acid can kill bacteria in the water to achieve disinfection, reducing the risk of disease transmission. In actual use, salt can be actively added to the injected tap water to enhance the deodorization and disinfection effects.

[0007] Furthermore, in the pet feces treatment device described above, the anode conductor and the cathode conductor are disposed on the side wall of the collection chamber.

[0008] Furthermore, in another embodiment of the pet feces treatment device described above, the anode conductor and the cathode conductor are disposed on the bottom surface of the collection chamber.

[0009] Furthermore, in another embodiment of the pet feces treatment device described above, the anode conductor and the cathode conductor are disposed on the side wall and bottom surface of the collection chamber, respectively.

[0010] Furthermore, in the pet feces treatment device described above, an anode conductor and a cathode conductor are disposed on the side wall of the collection chamber. The anode conductor includes a first main body and a first extension branch. The first main body is disposed on the side wall of the collection chamber, one end of the first extension branch is connected to the first main body for conduction, and the other end of the first extension branch extends along the side wall of the collection chamber. The cathode conductor includes a second main body and a second extension branch. The second main body is disposed on the side wall of the collection chamber, one end of the second extension branch is connected to the second main body for conduction, and the other end of the second extension branch extends along the side wall of the collection chamber. This increases the contact area between the anode conductor, the cathode conductor, and the water.

[0011] Furthermore, in the pet feces treatment device described above, the first and second extension branches are arranged alternately in the vertical direction. This makes the layout of the anode and cathode conductors more compact and improves space utilization.

[0012] Furthermore, in another embodiment of the pet feces treatment device described above, an anode conductor and a cathode conductor are disposed on the bottom surface of the collection chamber. The anode conductor includes a third main body and a third extension branch. The third main body is disposed on the bottom surface of the collection chamber, one end of the third extension branch is connected to the third main body for conduction, and the other end of the third extension branch extends around the central axis of the collection chamber. The cathode conductor includes a fourth main body and a fourth extension branch. The fourth main body is disposed on the bottom surface of the collection chamber, one end of the fourth extension branch is connected to the fourth main body for conduction, and the other end of the fourth extension branch extends around the central axis of the collection chamber. This increases the contact area between the anode conductor, cathode conductor, and water.

[0013] Furthermore, in the pet feces treatment device described above, the third and fourth extension branches are arranged alternately from the center of the collection chamber outwards. This makes the layout of the anode and cathode conductors more compact, improving space utilization.

[0014] Furthermore, in the pet feces treatment device described above, a main agitator is provided at the bottom of the collection chamber; the rotation axis of the main agitator is parallel to or perpendicular to the opening of the collection chamber. The main agitator is used to agitate fecal lumps and mix the agitated fecal lumps with tap water to form a mortar.

[0015] Furthermore, in the pet feces treatment device described above, the collection chamber is also equipped with a secondary agitator; the rotation axis of the secondary agitator is perpendicular to the rotation axis of the primary agitator. The secondary agitator is used to improve the agitation effect of fecal lumps. In actual use, the secondary agitator can be placed near the discharge port of the collection chamber, so that the secondary agitator also plays an auxiliary role in discharging the slurry from the collection chamber.

[0016] The advantages of this utility model are: simple structure, reasonable design, and less odor during operation. Attached Figure Description

Detailed Implementation

[0032] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] like Figures 1 to 5 According to Embodiment 1, a pet feces treatment device includes a collection chamber 1, a first anode conductor 2, a first cathode conductor 3, and a DC power supply (not shown in the drawings). The collection chamber 1 has an upper-opening collection cavity. The first anode conductor 2 and the first cathode conductor 3 are disposed in the collection cavity. The anode output terminal of the DC power supply is connected to the first anode conductor 2 and the cathode output terminal of the DC power supply is connected to the first cathode conductor 3.

[0035] The working principle of this embodiment is as follows:

[0036] In use, feces and litter blocks are transported to the collection chamber of collection compartment 1 for collection. Tap water is then injected into the collection chamber, and the tap water comes into contact with the first anode conductor 2 and the first cathode conductor 3. Under automatic or manual control, a DC power supply energizes the first anode conductor 2 and the first cathode conductor 3, causing an electrolytic reaction in the water within the collection chamber. Because tap water contains residual chlorine, and some pet litter components may contain small amounts of chloride salts, hypochlorous acid is generated during the electrolytic reaction of the mixture of feces and litter blocks and tap water. Hypochlorous acid reacts chemically with odor-causing substances in the water to achieve deodorization, resulting in less odor emitted by this pet feces treatment device during operation. In addition, hypochlorous acid can kill bacteria in the water to achieve disinfection, reducing the risk of disease transmission. In actual use, salt can be actively added to the injected tap water to enhance the deodorization and disinfection effects.

[0037] like Figure 3 and Figure 4 As shown, the first anode conductor 2 and the first cathode conductor 3 are disposed on the side wall of the collecting cavity; the first anode conductor 2 includes a first main body 21 and three first extension branches 22, and the first cathode conductor 3 includes a second main body 31 and two second extension branches 32. The first main body 21 and the second main body 31 are disposed on the side wall of the collecting cavity, and the first main body 21 and the second main body 31 are on the same horizontal plane and are disposed close to each other. The first main body 21 and the second main body 31 have a rectangular structure, and one of the first extension branches 22... The first extension branch 22 is connected to the side of the first main body 21 away from the second main body 31. The other end of the first extension branch 22 extends horizontally along the inner wall of the collection cavity and is located close to the second main body 31. One end of the second extension branch 32 is connected to the side of the second main body 31 away from the first main body 21. The other end of the second extension branch 32 extends horizontally along the inner wall of the collection cavity and is located close to the first main body 21. The three first extension branches 22 and the two second extension branches 32 are arranged alternately in the vertical direction.

[0038] By forming a first extension branch 22 on the first anode conductor 2 and a second extension branch 32 on the first cathode conductor 3, the contact area between the first anode conductor 2 and the first cathode conductor 3 and the water in the collection chamber is increased, thereby improving the reaction rate of the electrolysis reaction in the water and enhancing the deodorization and disinfection effects. The staggered arrangement of the first extension branch 22 and the second extension branch 32 in the vertical direction makes the layout structure of the first anode conductor 2 and the first cathode conductor 3 more compact, maximizing the contact area within the limited layout space, further improving the reaction rate of the electrolysis reaction.

[0039] like Figure 3As shown, the collection chamber 1 includes an upper chamber 11 and a lower chamber 12. A collection space 13 is formed on the upper chamber 11. The upper chamber 11 and the lower chamber 12 enclose a crushing space 14. The collection space 13 and the crushing space 14 together constitute the collection cavity. A collection port 15 is formed on the collection space 13, which communicates with the top surface of the upper chamber 11. The collection space 13 has a funnel-shaped structure that gradually narrows from top to bottom. The crushing space 14 is located directly below the collection space 13. The crushing space 14 and the collection space 13 are connected by a material collection port 16. A discharge port 17 is formed on the crushing space 14, which communicates with the outer surface of the lower chamber 12. The first anode conductor 2 and the first cathode conductor 3 are both disposed in the crushing space 14. The collection chamber also includes a first crushing element 6 and a first drive motor 7. The first crushing element 6 is rotatably disposed in the crushing space 14. The first drive motor 7 is used to drive the first crushing element 6 to rotate. In use, fecal sand blocks are fed into the collection space 13 through the collection port 15. Since the collection space 13 has a funnel-shaped structure, the fecal sand blocks gather towards the material collection port 16 under their own weight and fall into the crushing space 14. Tap water is injected into the collection chamber so that the first anode conductor 2 and the first cathode conductor 3 in the crushing space 14 are submerged by tap water. DC power is supplied to the first anode conductor 2 and the first cathode conductor 3, and the first drive motor 7 drives the first crushing component 6 to rotate, so that the fecal sand blocks are crushed and mixed with tap water to form slurry. During the crushing process, the hypochlorous acid generated by the electrolysis of the water in the collection chamber plays a role in deodorization and disinfection. Finally, the slurry is discharged from the collection chamber 1 through the discharge port 17.

[0040] like Figure 3 and Figure 5 As shown, the first grinding component 6 includes a disc portion 61 and several grinding blade portions 62. The disc portion 61 is rotatably disposed in the grinding space 14 and faces the collection port 16. The rotation axis of the disc portion 61 is arranged along the hole axis of the collection port 16. The grinding blade portions 62 have a pointed structure, and several grinding blade portions 62 are disposed on the side of the disc portion 61 facing the collection port 16. During operation, fecal pellets come into contact with the disc portion 61 and are driven by centrifugal motion. The grinding blade portions 62 crush the fecal pellets, thereby improving the grinding effect. The first drive motor 7 is located on the side of the collection chamber 1. The first grinding component 6 is coaxially and fixedly connected to a transmission gear 10. The transmission gear 10 is connected to the output shaft of the first drive motor 7 via a belt 20, thereby reducing the height of this pet feces treatment device.

[0041] like Figure 3 and Figure 5As shown, the first agitator 6 further includes a plurality of blades 63, which are disposed on the outer peripheral edge of the disc portion 61 and are evenly distributed around the rotation axis of the disc portion 61. The blades 63 can crush fecal sand blocks, further improving the agitation effect. The blades 63 can also promote the flow of water in the agitation space 14, accelerate the reaction speed of the electrolysis reaction, and improve the deodorization and disinfection effect.

[0042] Example 2

[0043] like Figures 6 to 10 This is a pet feces treatment device according to Embodiment 2. Embodiment 2 differs from Embodiment 1 in that it further includes a second anode conductor 4 and a second cathode conductor 5, but excludes the first anode conductor and the first cathode conductor. The second anode conductor 4 and the second cathode conductor 5 are disposed on the bottom surface of the grinding space 14. The second anode conductor 4 includes a third main body 41 and four third extension branches 42, and the second cathode conductor 5 includes a fourth main body 51 and four fourth extension branches 52. The third main body 41 and the fourth main body 51 are respectively disposed on opposite sides of the bottom surface of the grinding space 14, and are rectangular in structure. The third main body 41 is connected to the anode output terminal of the DC power supply, and the fourth main body 51 is connected to the cathode output terminal of the DC power supply. One end of each of the two third extension branches 42 is connected to one side of the third main body 41. The other two third extension branches 42 are connected to the other side of the third main body 41, and the other ends of the four third extension branches 42 extend around the central axis of the churning space 14 and are disposed near the fourth main body 51 on the bottom surface of the churning space 14; the other two fourth extension branches 52 are connected to one side of the fourth main body 51, and the other two fourth extension branches 52 are connected to the other side of the fourth main body 51, and the other ends of the four fourth extension branches 52 extend around the central axis of the churning space 14 and are disposed near the third main body 41 on the bottom surface of the churning space 14; the two third extension branches 42 and the two fourth extension branches 52 are arranged alternately from the center of the churning space 14 to the surrounding area, and the other two third extension branches 42 and the other two fourth extension branches 52 are arranged alternately from the center of the churning space 14 to the surrounding area. This structure allows for a more compact layout of the second anode conductor 4 and the second cathode conductor 5, maximizing their contact area within a limited space and improving the reaction rate of the electrolysis reaction.

[0044] like Figure 8As shown, the pulverizing space 14 includes a buffer section 141 and a pulverizing section 142. The buffer section 141 is a cylindrical structure with its axis arranged vertically. The buffer section 141 is located directly below the collecting space 13 and is connected to the collecting space 13 via a material collection port 16. The second anode conductor 4 and the second cathode conductor 5 are both disposed in the buffer section 141. The pulverizing section 142 is a cylindrical structure with its axis arranged horizontally. The pulverizing section 142 is located beside the buffer section 141 in the horizontal direction. The 42 and the buffer section 141 are connected by a suction port 143. The axis of the suction port 143 is collinear with the axis of the crushing section 142. The discharge port 17 is formed on the crushing section 142. This embodiment also includes a second crushing element 8 and a second drive motor 9, but does not include the first crushing element and the first drive motor. The second crushing element 8 is rotatably disposed in the crushing section 142. The second crushing element 8 is directly opposite the suction port 143, and the rotation axis of the second crushing element 8 is arranged along the axis of the suction port 143. The second drive motor 9 is used to drive the second crushing element 8 to rotate. In use, the fecal sand blocks in the collection space 13 pass through the collection port 16, the buffer section 141, and the suction port 143 in sequence before entering the crushing section 142. The second crushing element 8 crushes the fecal sand blocks in the crushing section 142. Compared with embodiment 1, this design in this embodiment can prolong the contact time between the fecal sand blocks and hypochlorite, and improve the deodorization and disinfection effect.

[0045] like Figure 8 and Figure 10 As shown, the second agitator 8 includes a turntable 81 and a plurality of reamer sections 82. The turntable 81 is rotatably disposed in the agitator 142 and faces the suction port 143. The reamer sections 82 have a curved structure, and the plurality of reamer sections 82 are disposed on the side of the turntable 81 facing the suction port 143, arranged in a ring array with the rotation axis of the turntable 81 as the center. The second drive motor 9 is located beside the collection chamber 1. The output shaft of the second drive motor 9 is arranged horizontally and coaxially fixed with the turntable 81 of the second agitator 8. The end of the output shaft of the second drive motor 9 passes through the agitator and is located in the suction port 143. Two slits 91 are formed on the end of the output shaft of the second drive motor 9, so that the fecal sand in the suction port 143 can be agitated by the output shaft of the second drive motor 9 to avoid the suction port 143 being blocked.

[0046] Example 3

[0047] like Figures 11 to 13This is a pet feces treatment device according to Embodiment 3. The difference between Embodiment 3 and Embodiment 2 is that this embodiment also includes the first anode conductor 2, the first cathode conductor 3, the first agitator 6, and the first drive motor 7 of Embodiment 1. The first anode conductor 2 and the first cathode conductor 3 are disposed on the inner side wall of the buffer section. The first main body of the first anode conductor 2 and the second main body of the first cathode conductor 3 are respectively located on both sides of the suction port 143. The first agitator 6 is rotatably disposed in the buffer section. The first drive motor 7 is located on the lower side of the collection chamber 1. The output shaft of the first drive motor 7 is coaxially fixed with the disc part of the first agitator 6, thereby driving the first agitator 6 to rotate. This embodiment improves the reaction rate of the electrolysis reaction of the water in the collection chamber 1 by simultaneously setting the first anode conductor 2, the first cathode conductor 3, the second anode conductor 4, and the second cathode conductor 5, thereby enhancing the deodorization and disinfection effects. By simultaneously setting the first agitator 6, the second agitator 8, the first drive motor 7, and the second drive motor 9, where the first agitator 6 serves as the main agitator and the second agitator 8 serves as the auxiliary agitator, the fecal sand blocks undergo preliminary agitation by the first agitator 6 and then secondary agitation by the second agitator 8, improving the agitation effect of the fecal sand blocks. The second agitator 8 also assists in discharging the slurry from the collection chamber 1 through the discharge port 17.
