Description

Technical Field

[0001] This invention is a cat litter box drawer, belonging to the field of pet supplies technology. Background Technology

[0002] Pets are animals and plants kept for emotional or psychological reasons. They are generally kept to alleviate loneliness or for entertainment. Among them, felines, which do not require much space to move around, are becoming an increasingly popular choice for families. Felines typically use litter boxes to store cat litter, and the litter in the litter box needs to be cleaned regularly. To make cleaning the litter box easier, drawers are usually designed on the litter box, and a detachable litter net is used to lay the litter.

[0003] In existing technology, the opening of the litter net connected to the litter box drawer is always exposed. When cleaning, the litter box drawer is first pulled out. However, pulling it out easily causes the litter box drawer itself to shake, which increases the probability of litter spilling and the probability of the odor from the feces mixed in with the litter spreading. This makes the fecal odor easily pollute the cleaning environment, resulting in poor comfort for cleaning personnel and low environmental protection.

[0011] Furthermore, a protective element is provided at the inner end of the third magnetic column, and the protective element is located on the outer side of the annular electromagnet, and the protective element has an annular structure.

[0012] Furthermore, the inner wall of the conical cover is provided with a plurality of transversely arranged U-shaped guide plates at equal intervals, the limiting rod passes through the U-shaped guide plates, and the U-shaped guide plates are slidably connected to the limiting rod;

[0013] The movable plate is located inside the U-shaped guide plate and extends beyond the upper part of the U-shaped guide plate. The movable plate is slidably connected to the U-shaped guide plate, and the elastic element is located inside the U-shaped guide plate.

[0014] Furthermore, the snap-fit ​​component includes two connecting plates, which are symmetrically arranged on the upper front side of the front bracket, with the connecting plates located on the inner side of the light rod. A U-shaped snap-fit ​​plate is installed between the two connecting plates on the front side. The upper end of the box body is recessed downward to form a second groove, which is located directly below the U-shaped snap-fit ​​plate. The front end of the box body is recessed backward to form a first groove, and the first groove and the second groove are arranged in communication. A horizontally arranged rotating shaft is rotatably connected inside the second groove.

[0015] An L-shaped movable plate is provided at the outer end of the rotating shaft, and the horizontal part of the L-shaped movable plate extends to the front end of the first groove.

[0018] The beneficial effects of this invention are:

[0019] 1. Under the weight of the cat litter on the litter net, the front rack and the second magnetic plate move backward. Under the action of the first and second magnetic plates, the front rack and the rear rack fit together and seal the opening of the litter net. Then, the litter net can be removed from the box, making it easy to clean the cat litter. This effectively reduces the probability of cat litter spillage and the probability of odor diffusion from feces mixed in the cat litter, improving the comfort of the operator and making it highly environmentally friendly.

[0020] 2. A conical cylinder is used to collect the falling litter net. Then, a ring electromagnet and a third magnetic column are used to move the limiting rod inward and into the conical cover, thereby releasing the restriction on the binding rubber band. The binding rubber band is then fitted onto the outer end of the collected litter net and closes and binds the opening of the litter net, making it easy to bind the litter net and remove it. This further effectively reduces the probability of litter spillage and odor diffusion.

[0021] 3. As the front bracket moves backward along the smooth rod, the cleaning brush moves backward along the smooth rod, cleaning the upper outer end of the smooth rod. This effectively ensures that the front bracket can move backward normally and effectively seals the opening of the litter net, effectively reducing the probability of litter spillage and odor diffusion.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, a litter box drawer is provided, including a box body 3. A horizontally arranged rear bracket 1 is installed on the upper rear edge of the box body 3. The rear bracket 1 provides a mounting carrier for components such as the first hanging post 12. Two light rods 2 that pass through the front bracket 5 and the mounting groove are symmetrically arranged between the front end of the rear bracket 1 and the inner front wall of the box body 3. The two light rods 2 work together to guide the movement of the front bracket 5 and then attach the front bracket 5 to the upper end of the box body 3. The front bracket 5 provides a mounting carrier for components such as the second hanging post 51.

[0036] Two first hanging posts 12 are symmetrically arranged on the upper end of the rear hanging frame 1, and two second hanging posts 51 are symmetrically installed on the upper end of the front hanging frame 5. The two first hanging posts 12 and the two second hanging posts 51 work together to install the cat litter net. Then, the first magnetic plate 11 located between the two light rods 2 is embedded in the front end of the rear hanging frame 1, and the second magnetic plate 56 located in front of the first magnetic plate 11 and arranged to attract each other with the first magnetic plate 11 is embedded in the rear end of the front hanging frame 5. The first magnetic plate 11 and the second magnetic plate 56 work together to make the front hanging frame 5 and the rear hanging frame 1 attract each other.

[0037] Two mounting grooves are formed on the upper surface of the front bracket 5, facing downwards, and located on the outer side of the second mounting post 51. The mounting grooves provide installation space for the sliding bearing 54. The sliding bearing 54, which is installed on the front wall inside the mounting groove and extends to the front end of the front bracket 5, is slidably connected to the outer end of the smooth rod 2. The sliding bearing 54 enables the smooth rod 2 to slide and connect with the front bracket 5, effectively reducing the friction between the smooth rod 2 and the smooth rod 2. Two connecting plates 52 located on the inner side of the smooth rod 2 are symmetrically arranged on the upper side of the front end of the front bracket 5. The two connecting plates 52 work together to connect the U-shaped clamp 53 with the front bracket 5. The U-shaped clamp 53 is then installed on the front side between the two connecting plates 52. The U-shaped clamp 53 restricts the installation of the L-shaped mounting plate 31.

[0038] A second groove 35 is formed by recessing the upper surface of the box body 3 downwards, located directly below the U-shaped card plate 53. The second groove 35 provides installation space for components such as the rotating shaft 34. A first groove 32 is formed by recessing the front surface of the box body 3 backwards, which is connected to the second groove 35. The first groove 32 provides space for pulling out the box body 3. The horizontally arranged rotating shaft 34 is rotatably connected inside the second groove 35. The L-shaped movable plate 33 is rotatably connected to the box body 3 through the rotating shaft 34. The L-shaped movable plate 33, which extends horizontally to the front end of the first groove 32 and vertically to the upper side of the second groove 35, is set on the outer end of the rotating shaft 34. The L-shaped hanging plate 31 can be operated by using the L-shaped movable plate 33.

[0039] The horizontal portion of the L-shaped hanging plate 31, which is integral with the L-shaped movable plate 33 and has a horizontal portion that passes through the two vertical portions of the U-shaped clamping plate 53 and is located on the rear side of the U-shaped clamping plate 53, is installed on the upper end of the vertical portion of the L-shaped movable plate 33. The L-shaped hanging plate 31 and the U-shaped clamping plate 53 work together to restrict the installation of the front hanger 5. An inclined surface is opened on the rear end face of the vertical portion of the L-shaped hanging plate 31. The inclined surface facilitates the movement of the L-shaped hanging plate 31 to the rear side of the U-shaped clamping plate 53. The first magnetic post 36 is installed on the bottom end of the second groove 35. The second magnetic post 37, which is located directly above the first magnetic post 36 and is arranged to repel the first magnetic post 36, is placed on the lower end of the horizontal portion of the L-shaped hanging plate 31. The first magnetic post 36 and the second magnetic post 37 work together to apply an upward force to the L-shaped hanging plate 31, thereby effectively engaging the L-shaped hanging plate 31 and the U-shaped clamping plate 53.

[0040] When using it, first assemble the four corners of the cat litter net with the two first hanging posts 12 and the two second hanging posts 51 respectively, so as to install the cat litter net onto the box body 3. Then, spread the cat litter on the upper part of the cat litter net and push the box body 3 into the cat litter box to install the cat litter into the cat litter box.

[0041] When it is necessary to clean the cat litter in the litter box, the operator first inserts his hand into the first groove 32 and pulls the L-shaped movable plate 33 upward, thereby causing the L-shaped movable plate 33 to rotate around the pivot 34, thereby causing the L-shaped hanging plate 31 to swing downward, and then causing the L-shaped hanging plate 31 to move to the underside of the U-shaped card plate 53, thereby releasing the restriction on the front hanging bracket 5.

[0042] Then the weight of the cat litter itself will exert downward pressure on the litter net, causing the front bracket 5 to move backward along the light rod 2, thereby causing the second magnetic plate 56 to move backward, which in turn reduces the distance between the first magnetic plate 11 and the second magnetic plate 56, and generates an adsorption force between the first magnetic plate 11 and the second magnetic plate 56. Then, under the action of the adsorption force, the front bracket 5 continues to move backward, thereby causing the front bracket 5 and the rear bracket 1 to fit together and close the opening of the litter net.

[0043] Then pull the box 3 outward to remove it from the litter box. Then, detach the litter from the two first hanging posts 12 and the two second hanging posts 51, and hold the litter net with the opening closed. Then, pull the front hanging frame 5 forward to separate it from the rear hanging frame 1. Then, remove the litter net from the box 3 to facilitate the cleaning of the litter, effectively reduce the probability of litter spillage, and effectively reduce the probability of odor diffusion from feces mixed in the litter, improve the comfort of the operator, and is highly environmentally friendly.

[0044] Example 2: The front bracket 5 and the rear bracket 1 are fitted together to seal the opening of the litter net, which effectively reduces the probability of litter spillage and odor diffusion. However, when removing the litter net, the front bracket 5 and the rear bracket 1 are separated first, which makes the edge of the litter net prone to pulling down. This increases the probability of gaps appearing at the opening of the litter net, leading to a higher probability of leakage of the litter collected inside the litter net, and a higher probability of the odor of feces mixed in the litter leaking out.

[0045] To solve the above problems, such as Figure 1 , Figure 2 and Figure 5 As shown, a conical cover 4, which is narrower at the top and wider at the bottom, is installed on the bottom of the box 3. The conical cover 4 expands the binding rubber band. A conical cylinder 41, which extends to the top of the conical cover 4 and is wider at the top and narrower at the bottom, is placed on the top of the conical cover 4. The conical cylinder 41 can collect the falling cat litter net. Multiple limiting rods 45, which are arranged horizontally, extend out of the outside of the conical cover 4 and pass through the U-shaped guide plate 46, are equidistantly and movable on the inner wall of the conical cover 4. The multiple limiting rods 45 work together to restrict the binding rubber band to be installed on the outer end of the conical cover 4.

[0046] An annular electromagnet 47 located inside the conical cover 4 is placed on the outer end of the conical cylinder 41. A third magnetic column 42 located directly outside the annular electromagnet 47 and arranged to attract each other with the annular electromagnet 47 is installed on the inner end of the limiting rod 45. The annular electromagnet 47 and the third magnetic column 42 work together to drive the limiting rod 45 to move inward. A protective component with an annular structure located outside the annular electromagnet 47 is placed on the inner end of the third magnetic column 42. The protective component effectively prevents the annular electromagnet 47 and the third magnetic column 42 from colliding. The protective component can be an annular rubber pad.

[0047] Multiple U-shaped guide plates 46 arranged laterally and slidably connected to the limiting rod 45 are equidistantly arranged on the inner wall of the conical cover 4. The limiting rod 45 is supported by the U-shaped guide plates 46. A movable plate 43 arranged vertically, located inside the conical cover 4 and inside the U-shaped guide plate 46, extending out of the upper side of the U-shaped guide plate 46 and slidably connected to the U-shaped guide plate 46, is placed on the upper end of the limiting rod 45. The U-shaped guide plate 46 and the movable plate 43 work together to guide the movement of the limiting rod 45. An elastic element 44 located on the upper side of the limiting rod 45, inside the U-shaped guide plate 46 and arranged laterally is placed between the inner end of the movable plate 43 and the inner wall of the conical cover 4. The limiting rod 45 is returned to its original position by the elastic element 44. The elastic element 44 can be a spring.

[0048] When in use, first turn on the circuit of the ring electromagnet 47 so that the ring electromagnet 47 and multiple third magnetic pillars 42 generate an attraction force. Under the action of the attraction force, multiple limiting rods 45 move inward, and then multiple limiting rods 45 enter the conical cover 4. The inward movement of the limiting rods 45 will cause the moving plate 43 to move inward and stretch the elastic element 44, so that the elastic element 44 generates an elastic force.

[0049] Then, the binding rubber band is fitted onto the outer end of the conical cover 4, and the binding rubber band is positioned under the limiting rod 45. Then, the circuit of the annular electromagnet 47 is disconnected, and under the elastic force of the elastic element 44, the moving plate 43 moves outward, which in turn moves the limiting rod 45 outward, so that the limiting rod 45 extends outward from the outer side of the conical cover 4, thereby restricting the binding rubber band to be installed on the outer end of the conical cover 4.

[0050] When it is necessary to clean the cat litter in the litter box, the operator uses the L-shaped movable plate 33 to move the L-shaped hanging plate 31 to the underside of the U-shaped card plate 53, thereby releasing the restriction on the front hanging frame 5. At this time, under the weight of the cat litter itself, the front hanging frame 5 and the second magnetic plate 56 move backward, and under the action of the first magnetic plate 11 and the second magnetic plate 56, the front hanging frame 5 and the rear hanging frame 1 fit together and the opening of the cat litter net is closed.

[0051] The cat litter net, under the weight of the cat litter, will cause the middle part of the cat litter net to fall downwards. The falling cat litter net enters the cone-shaped cylinder 41 and is collected by the cone-shaped cylinder 41. Then, the box body 3 is pulled outwards, so that the box body 3 is pulled out of the cat litter box. Then, the circuit of the ring electromagnet 47 is turned on, so that the ring electromagnet 47 and multiple third magnetic pillars 42 generate an attraction force. Under the action of the attraction force, multiple limiting rods 45 move inwards and enter the cone-shaped cover 4, thereby releasing the restriction on the binding elastic band. Then, the binding elastic band moves upwards along the cone-shaped cover 4 and is fitted onto the outer end of the collected cat litter net. At this time, the binding elastic band will close and bind the opening of the cat litter net.

[0052] Then, the cat litter is detached from the two first hanging posts 12 and the two second hanging posts 51. Then, the front hanging frame 5 is pulled forward to separate the front hanging frame 5 from the rear hanging frame 1. Then, the bundled cat litter net is taken out from the box 3, which makes it easy to bundle the cat litter net and remove it, further effectively reducing the probability of cat litter spillage and odor diffusion.

[0053] Example 3: The front bracket 5 and the rear bracket 1 are fitted together to seal the opening of the litter net, which effectively reduces the probability of litter spillage and odor diffusion. In order to ensure that the front bracket 5 and the rear bracket 1 can effectively seal the opening of the litter net, a smooth rod 2 is used to guide the sealing movement. However, impurities are easily attached to the upper outer end face of the smooth rod 2, which can easily hinder the sealing movement during the sealing process, thus affecting the sealing effect of the litter net opening.

[0054] To solve the above problems, such as Figure 1 , Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, a U-shaped mounting plate 55, located outside the light rod 2 and with its opening facing downward, is installed between the rear end of the sliding bearing 54 and the front wall inside the mounting groove. The U-shaped mounting plate 55 provides a mounting carrier for the cleaning soft brush 57. The cleaning soft brush 57, which is attached to the upper outer end of the light rod 2, is placed on the inner wall of the U-shaped mounting plate 55. The cleaning soft brush 57 cleans the upper outer end face of the light rod 2. The collection box 58, located in the sliding bearing 54 and extending to the rear end of the front bracket 5 and directly below the opening of the U-shaped mounting plate 55, is slidably connected to the bottom end inside the mounting groove. The collection box 58 is used to collect the cleaned impurities.

[0055] The metal rod 581 is placed on the front middle of the collection box 58, and the fourth magnetic column 582, which is attached to the front of the metal rod 581 and adsorbs the metal rod 581 and is located on the lower side of the sliding bearing 54, is installed on the front wall inside the mounting groove. The metal rod 581 is adsorbed by the fourth magnetic column 582. The metal rod 581 and the fourth magnetic column 582 work together to restrict the installation of the collection box 58.

[0056] When in use, first release the restriction on the front bracket 5, and under the weight of the cat litter itself, the front bracket 5 moves backward along the light rod 2, and the cleaning soft brush 57 moves backward along the light rod 2. The cleaning soft brush 57 will clean the upper outer end of the light rod 2, effectively ensuring that the front bracket 5 can move backward normally, and effectively ensuring the sealing effect of the cat litter net opening, effectively reducing the probability of cat litter spillage and odor diffusion.

[0057] During the cleaning process of the clean rod 2, the cleaned impurities will fall into the collection box 58, thereby collecting the cleaned impurities. After the cat litter net is removed from the box body 3, the collection box 58 can be pulled backward to separate the collection box 58 from the installation slot, so as to conveniently clean the impurities collected in the collection box 58.

[0058] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
