Description

A portable pet waste collection device and its usage method Technical Field

[0001] This invention belongs to the field of pet supplies and relates to a waste collection device, specifically a portable pet waste collection device and its usage method. Background Technology

[0002] Existing portable pet waste collection devices generally achieve the effect of being easy to carry and store by improving the extension and retraction of the handle or the folding of the entire waste collection device.

[0003] Pet waste collection devices generally consist of a bag-supporting unit that expands the bag and a telescopic rod folded and installed at the rear of the bag-supporting unit for hand operation. The bag-supporting unit is a scissor-type structure, such as the Chinese patent with publication number CN220140496U, entitled "A Folding and Retractable Pet Waste Collection Device Based on Sliding Sleeve Connection." In this patent, the scissor-type structure is retracted and fixed by the cooperation of a rear sloping locking block and a locking groove. This method has many components, making assembly inconvenient. Furthermore, the sloping locking block and locking groove are prone to misalignment, affecting the retraction limit.

[0004] In addition, the existing portable pet waste collection devices have many limitations: First, if not all dog feces are collected into the bag, manual cleaning is required, posing a hygiene risk of contact with feces; second, the "one bag, one waste" model requires changing the bag midway through a walk when the dog defecates again, which is cumbersome; third, using a single bag increases user costs, and odors are noticeable if the bag is not disposed of promptly; fourth, existing waste collection devices lack effective designs for reuse and odor control, affecting user experience and environmental friendliness. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a portable pet waste collection device that is convenient to retract and limit, easy to process, and can improve the speed of retraction and extension. Furthermore, this invention provides a method of using the portable pet waste collection device, enabling functions such as waste collection, odor control, and reuse, thus solving problems related to hygiene risks, inconvenient bag replacement, and high costs.

[0006] The technical problem solved by this invention is achieved through the following technical solution:

[0007] A portable pet waste collection device includes a bag-supporting unit and an operating rod mounted on the rear of the bag-supporting unit via a mounting base. The bag-supporting unit includes a scissor-fork telescopic assembly. The device is characterized by further including a scissor-fork retraction limiting assembly, which includes a locking hook. A locking hook and a locking groove are respectively provided at the intermediate hinge points at both ends of the scissor-fork telescopic assembly. The scissor-fork telescopic assembly achieves retraction limiting by hooking the locking hook onto the locking groove.

[0008] Furthermore, the scissor lift retraction limiting assembly also includes a locking slot sleeve. The hinge pin cap at the hinge point in the middle of the scissor lift assembly is spaced apart from the scissor blade of the scissor lift assembly. The pin shank between the hinge pin cap and the scissor blade of the scissor lift assembly forms a locking groove. A locking slot sleeve is fitted onto the locking groove. The outer diameter of the locking slot sleeve is adapted to the hook body of the locking hook. The locking hook is attached to the locking slot sleeve.

[0009] Furthermore, the bag support unit also includes a main tube, a main fixing sleeve, a main sliding sleeve, a tension spring, guide rods, a front auxiliary sliding sleeve, and a rear auxiliary sliding sleeve. The main fixing sleeve is fixedly fitted to the front end of the main tube, and the main sliding sleeve is slidably fitted to the rear end of the main fixing sleeve on the main tube. A sliding elongated hole is opened at the rear of the main tube. Guide rods are symmetrically arranged on both sides of the main tube, and a front auxiliary sliding sleeve and a rear auxiliary sliding sleeve are respectively fitted onto each guide rod. The hinge point at the middle of the front end of the scissor lift assembly is fixed to the main fixing sleeve by a first screw. The screw extends into the interior of the main tube and protrudes from the bottom of the main tube before being fixed by a nut. The hinge point at the middle of the rear end of the scissor telescopic assembly is fixed to the main sliding sleeve by a second screw. This second screw extends into the interior of the main tube and protrudes from the bottom of the main tube before being fixed by a nut. A tension spring is connected between the first screw and the second screw inside the main tube. The main sliding sleeve slides in the sliding elongated hole following the second screw. The hinge points at both ends of the scissor telescopic assembly are connected to the front and rear auxiliary sliding sleeves by a third screw.

[0010] Furthermore, the scissor telescopic assembly consists of two sets, which are symmetrically arranged at the upper and lower ends of the main tube and guide rod.

[0011] Furthermore, the bag support unit also includes a bag clamping assembly, which includes clamping tabs. A clamping opening is provided at the front end of the front auxiliary sliding sleeve, and clamping tabs are hinged in each clamping opening to clamp the edge of the covering bag into the clamping opening.

[0012] Furthermore, a hinge platform flush with the bottom surface of each card slot is provided on the outer side of each card slot. One end of the card slot is hinged to the hinge platform, and the other end of the card slot is used to insert the edge of the bag into the card slot. A card bag reinforcement structure is also provided on the card bag assembly. A card protrusion is provided on the inner side of one end of the card slot, and the card protrusion forms the card bag reinforcement structure.

[0013] Furthermore, a mounting protrusion is provided on the mounting plate at the position corresponding to the hinge platform. One end of the mounting protrusion has an arc-shaped structure. A mounting notch is provided at the top end of the mounting opening facing the mounting protrusion. The mounting notch has an arc-shaped structure. The area between the mounting notch and its front end face has an arc-shaped smooth transition structure. The mounting protrusion, the mounting notch, and the smooth transition structure form a card pocket reinforcement structure.

[0014] Furthermore, the mounting base includes a mounting sleeve, a mounting block, and an operating rod connecting seat. The mounting sleeve is fixedly installed at the rear end of the main tube, and the mounting block is integrally formed on the mounting sleeve. A vertical mounting groove with an upward opening is opened at the upper end of the mounting block. The operating rod connecting seat includes a connecting platform and hinged ears spaced apart on the bottom surface of the connecting platform. Each hinged ear is inserted into the mounting groove and then rotatably connected through a rotating shaft. An operating rod is connected to the connecting platform.

[0015] A method for using a portable pet waste collection device, characterized by including a conventional waste collection method, a waste collection and replenishment method, and an odor control method.

[0016] The conventional method for connecting a toilet includes the following steps:

[0017] Step 1: Place the bag set on the front end of the guide rod, and use the clip of the bag clamping assembly to clamp the edge of the bag into the clamping opening. When you hear a "click" sound, it means that the bag is clamped in place.

[0018] Step 2: Open the operating lever and the bag support unit, extend the operating lever to the required length, and keep the angle between the two at a comfortable operating angle (maximum not exceeding 135 degrees);

[0019] Step 3: Position the bag over the pet's defecation area and use the open bag to catch the feces. After catching the feces, keep the bag opening facing upwards.

[0020] The aforementioned method for collecting and replenishing feces includes the following steps:

[0021] Step 1: Adjust the angle between the operating lever and the bag support unit to 180 degrees to ensure operational stability;

[0022] Step 2: Flip the poop collector so that the bottom of the bag is facing up and the opening is facing down, and attach it above the dog poop, with the two guide rods aligned parallel to the unattached dog poop.

[0023] Step 3: Simultaneously retract the sliding sleeves on both sides of the bag support unit (main sliding sleeve, front auxiliary sliding sleeve and rear auxiliary sliding sleeve move in sync) and guide rod. With the help of the scissor structure characteristics of the scissor telescopic assembly, the elastic action of the tension spring in the main fixed sleeve and the elastic action of the guide rod, the guide rod moves towards the middle to form a clamping action, pressing the dog feces into the bag opening.

[0024] Step 4: Quickly flip your wrist so that the opening of the bag is facing upwards. The dog poop will fall into the bottom of the bag under the influence of gravity, completing the re-collection.

[0025] The flavor control method includes the following steps:

[0026] Step 1: After each use, operate the scissor lift mechanism to engage the locking hook in the locking slot, closing the bag opening. The scissor lift will then retract and secure the bag, reducing odor diffusion.

[0027] Step 2: When the pet defecates a second time during a dog walk, release the latch of the scissor lift retraction limit component. The scissor lift retraction component will quickly unfold under the action of the tension spring. There is no need to change the cover bag. Repeat the regular poop collection or poop clamping and re-collection operation.

[0028] Step 3: After walking the dog, remove the bag and collect the waste. One bag can be used multiple times.

[0029] The advantages and positive effects of this invention are:

[0030] 1. This portable pet waste collection device significantly simplifies the structure and operation of retraction by replacing the existing locking and limiting structure, which uses a slope locking block and a slope groove on a locking rod, with a retraction limiting structure achieved through the engagement of a snap-fit ​​hook and a snap-fit ​​groove. This not only improves retraction efficiency and effectiveness but also reduces processing costs by minimizing the machining of related parts. This scissor retraction limiting component is an improvement on the existing scissor telescopic structure, requiring only a snap-fit ​​hook and a snap-fit ​​groove at the hinge point, making it simple and convenient.

[0031] 2. In this portable pet waste collection device, the tension spring is directly connected to the screw connected to the main sliding sleeve, eliminating the need for a sliding block. Compared with existing technologies, this simplifies the product structure and facilitates processing.

[0032] 3. In this portable pet waste collection device, the guide rod can serve as a rod for the front and rear sliding sleeves to slide, and the front end of the guide rod can also serve as a rod for opening the covering bag. Compared with the existing technology, there is no need to configure an additional covering bag mounting rod, and there is no need to worry about the covering bag mounting rod being pulled off when the covering bag is discarded due to the covering bag mounting rod not being installed securely.

[0033] 4. This portable pet waste collection device features a reinforced bag-locking structure. This structure serves two purposes: firstly, it indicates that the bag is properly secured, preventing it from detaching during use due to improper operation or insufficient locking; secondly, once the locking tab is in place, it prevents loosening and ensures stability during use. Furthermore, this structure departs from the traditional method of relying solely on friction to secure the bag. If the locking opening is large, it is difficult to secure the bag tightly, requiring high precision in the locking opening machining. This reinforced bag-locking structure addresses these precision requirements, making the entire device easier to manufacture and saving production costs.

[0034] 5. The portable pet waste collection device is easy to use. Its waste-collecting function eliminates the need for direct hand contact with feces, improving hygiene. The scissor-fork retraction limit component allows for quick closing and opening of the bag, eliminating the need to change bags during secondary waste collection, making operation convenient. One bag can be used multiple times, reducing bag consumption and lowering user costs. The folded design of the waste collection opening effectively reduces odor leakage, improving the comfort of the environment during dog walks. It simplifies the usage process, reduces operating costs, raises dog owners' awareness of waste collection, and reduces fecal pollution.

[0035] 6. This invention is scientifically and rationally designed, and has the advantages of convenient retraction and limiting, easy processing, improved retraction and extension speed, improved operation comfort, reduced waste collection cost, hygiene and environmental protection, and easy implementation. It is a highly innovative portable pet waste collection device and its usage method. Attached Figure Description

Detailed Implementation

[0046] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings:

[0047] As shown in Figures 1 and 2, a portable pet waste collection device includes a bag-supporting unit and an operating rod 7 mounted on the rear of the bag-supporting unit via a mounting base 5. The bag-supporting unit includes a scissor-fork telescopic assembly 3, and its innovation lies in that it also includes a scissor-fork retraction limiting assembly 4. The scissor-fork retraction limiting assembly includes a locking hook 13. A locking hook and a locking groove 15 are respectively provided at the middle hinge points at both ends of the scissor-fork telescopic assembly. The scissor-fork telescopic assembly achieves retraction limiting by hooking the locking hook onto the locking groove. The scissor-fork retraction limiting assembly also includes a locking groove sleeve. The hinge pin cap at the middle position of the scissor-fork telescopic assembly is spaced apart from the scissor blade 17 of the scissor-fork telescopic assembly. The nail rod portion between the hinge pin cap and the scissor blade of the scissor-fork telescopic assembly forms a locking groove. A locking groove sleeve is fitted onto the locking groove. The outer diameter of the locking groove sleeve is adapted to the hook body of the locking hook, and the locking hook is hooked onto the locking groove sleeve.

[0048] The aforementioned scissor lift retraction limiting component is designed based on the existing scissor lift structure. It only requires the design of a locking hook and a locking groove at the middle hinge point, making it simple, convenient, easy to process and use.

[0049] The bag-supporting unit further includes a main tube 19, a main fixing sleeve 14, a main sliding sleeve 20, a tension spring 18, a guide rod 1, a front auxiliary sliding sleeve 9, and a rear auxiliary sliding sleeve 8. A main fixing sleeve is fixedly fitted at the front end of the main tube, and a main sliding sleeve is slidably fitted at the rear end of the main fixing sleeve on the main tube. Sliding elongated holes 11 are opened on both the upper and lower walls of the rear part of the main tube. Guide rods are symmetrically arranged on both sides of the main tube, and a front auxiliary sliding sleeve and a rear auxiliary sliding sleeve are respectively fitted on each guide rod. In this embodiment, the scissor telescopic assembly consists of two sets, as shown in Figure 3. These two sets of scissor telescopic assemblies are symmetrically arranged at the upper and lower ends of the main tube and the guide rods, i.e.:

[0050] The hinge points at the front center of each scissor lift assembly are fixed to the main fixed sleeve by the cooperation of the first screw 16 and the nut. The first screw penetrates the interior of the main tube. The hinge points at the rear center of each scissor lift assembly are fixed to the main sliding sleeve by the second screw 21. The second screw penetrates the interior of the main tube. A tension spring is connected between the first screw and the second screw inside the main tube. The main sliding sleeve slides in the sliding elongated hole following the second screw. The hinge points at both ends of the scissor lift assembly are connected to the front and rear auxiliary sliding sleeves by the third screw.

[0051] The bag support unit also includes a bag clamping assembly, which includes a clamping piece 2. A clamping opening 29 is provided at the front end of the front auxiliary sliding sleeve. A hinge platform 28, which is flush with the bottom surface of each clamping opening, is provided on the outside of each clamping opening. One end of the clamping piece is hinged to the hinge platform, and the other end of the clamping piece is used to clamp the edge of the bag into the clamping opening.

[0052] To increase the stability of the card bag assembly, a card bag reinforcement structure is also provided on the card bag assembly. This card bag reinforcement structure has two implementation forms:

[0053] Example 1, as shown in Figure 5, has a latching protrusion 30 on one side of the inner edge of the latching opening, which forms a reinforced structure for the latch pocket. When the latching piece is pushed into the latching opening, the latching piece interferes with the latching protrusion. Under the elastic deformation of the latching piece, a "click" sound is emitted, indicating that the latching piece has been latched in place.

[0054] Example 2, as shown in Figures 6-7, includes a mounting protrusion 31 on the mounting piece corresponding to the hinge platform. One inner end of the mounting protrusion is arc-shaped, and a mounting notch, also arc-shaped, is provided at the top end of the mounting opening facing the mounting protrusion. The area between the mounting notch and its front face is a smooth, arc-shaped transition structure 32. The mounting protrusion, mounting notch, and smooth transition structure form a reinforced pocket structure. When the mounting protrusion engages with the mounting opening, a "click" sound is emitted, indicating that the mounting piece is properly engaged.

[0055] The reinforced structure of the card bag serves two purposes: firstly, it indicates that the card is properly inserted, preventing the bag from coming loose during use due to improper operation or lack of tightness; secondly, once the card is properly inserted, it also prevents loosening by being restrained, ensuring stability during use.

[0056] As shown in Figure 3, the mounting base includes a mounting sleeve 12, a mounting block 22, and an operating rod connecting seat 6. The mounting sleeve is fixedly installed at the rear end of the main tube. The mounting block is integrally formed on the mounting sleeve. A vertical mounting groove 26 with an upward opening is opened at the upper end of the mounting block. The operating rod connecting seat includes a connecting platform 23 and hinged ears 24 spaced apart on the bottom surface of the connecting platform. Each hinged ear is inserted into the mounting groove and then rotatably connected by a rotating shaft. An operating rod is connected to the connecting platform. The operating rod is a telescopic rod.

[0057] The mounting block not only facilitates the installation of the operating lever connector, but also provides a gripping distance between the operating lever and the bag support unit after the entire toilet is folded, making it convenient for the operator to hold and carry after folding.

[0058] Before use, this portable toilet collector has a covering bag 10 (a plastic bag with an open top, a hollow inner edge 25 at the top, and an insertion hole 27 on the edge, into which the end of the guide rod is inserted) pre-attached to the end of the guide rod. The bag edge is then secured in place using a locking clip. Opening and use is simple: 1. Open the operating rod outwards, extending it to the desired length; 2. Open the locking hook to allow the bag-opening unit to expand the covering bag. The entire process is simple and smooth, enabling quick waste collection and meeting the user's needs. The covering bag edge protects the guide rod from contamination. After collecting waste, the locking clip is opened, and the covering bag is discarded.

[0059] Depending on different usage requirements, the present invention can also provide functions such as stool collection and odor control.

[0060] The aforementioned method for collecting and replenishing feces includes the following steps:

[0061] Step 1: Adjust the angle between the operating lever and the bag support unit to 180 degrees to ensure operational stability;

[0062] Step 2: Flip the poop collector so that the bottom of the bag is facing up and the opening is facing down, and attach it above the dog poop, with the two guide rods aligned parallel to the unattached dog poop.

[0063] Step 3: Simultaneously retract the sliding sleeves and guide rods on both sides of the bag support unit (the main sliding sleeve, the front auxiliary sliding sleeve, and the rear auxiliary sliding sleeve move in sync). With the help of the scissor structure of the scissor telescopic assembly, the elasticity of the tension spring in the main fixed sleeve, and the elasticity of the guide rod (the guide rod is made of ABS material), the guide rod moves towards the middle to form a clamping action, pressing the dog feces into the bag opening.

[0064] Step 4: Quickly flip your wrist so that the opening of the bag is facing upwards. The dog poop will fall into the bottom of the bag under gravity, completing the re-collection.

[0065] The flavor control method includes the following steps:

[0066] Step 1: After each use, operate the scissor lift mechanism to engage the locking hook in the locking slot, closing the bag opening. The scissor lift will then retract and secure the bag, reducing odor diffusion.

[0067] Step 2: When the pet defecates a second time during a dog walk, release the latch of the scissor lift retraction limit component. The scissor lift retraction component will quickly unfold under the action of the tension spring. There is no need to change the cover bag. Repeat the regular poop collection or poop clamping and re-collection operation.

[0068] Step 3: After walking the dog, remove the bag and collect the waste. One bag can be used multiple times.

[0069] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
