Description

Technical Field

[0001] This utility model relates to the field of portable toilet technology, specifically to a non-drainage portable toilet. Background Technology

[0002] Currently, traditional portable toilets are mainly divided into two types: flush toilets and dry-seal toilets. Flushing toilets require connection to a water supply system, and wastewater discharge relies on the municipal pipe network, making them difficult to use in places without drainage conditions (such as the wild or construction sites). Dry-seal portable toilets usually use chemical degradation agents or plastic bags for sealing, which has the following problems:

[0003] Poor sealing: The drain opening of some dry-seal toilets is left open for a long time, causing odors to spread and affecting the user experience;

[0004] Inconvenient to operate: Some toilets require manual opening and closing of the lid, which requires extra operation before and after using the toilet and does not conform to the natural behavior of the human body;

[0005] Maintenance difficulties: The collection boxes are inconvenient to replace, and some have complex structures, making them prone to environmental pollution during cleaning;

[0006] To address the above problems, some improvements have been made in the existing technology, such as using gravity sensors or infrared sensors to control the opening and closing of the baffle. However, these solutions have the following shortcomings:

[0007] High cost: Electronic sensing devices require power and are susceptible to environmental factors (such as humidity, dust, etc.), resulting in a high failure rate;

[0008] Poor adaptability: The sensing method may misjudge due to different user postures, resulting in the barrier failing to open and close accurately;

[0009] Therefore, there is an urgent need for a simple, non-drainage mobile toilet that requires no external energy and can automatically adapt to the toileting action, in order to improve the convenience and hygiene of use. Utility Model Content

[0010] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a non-drainage portable toilet, which can effectively solve the problems mentioned in the background art.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] This utility model provides a non-drainage portable toilet, including a toilet body and a toilet chamber on the front of the toilet body. A toilet door is rotatably installed at the opening of the toilet chamber. A collection chamber is opened on the back of the toilet body. The toilet also includes: a collection box detachably installed in the collection chamber with an open top; a squat toilet fixedly installed at the bottom of the toilet chamber; and a defecation chamber connected to the collection chamber through the bottom. Two sealing baffles are rotatably installed at the upper opening of the defecation chamber. Two adjustable foot pedals are installed on the top sides of the squat toilet. When the two foot pedals are lowered, the two sealing baffles rotate synchronously but in opposite directions.

[0013] Furthermore, the two opposite outer walls of the toilet body are provided with exhaust vents that penetrate the toilet cavity, and several grid plates are installed obliquely inside the two exhaust vents. A door lock structure is installed between the toilet door and the inner wall of the toilet cavity.

[0014] Furthermore, a handle is vertically fixed to the back of the collection box, and rollers are installed at the four corners of the bottom of the collection box.

[0015] Furthermore, two first rotating rods and two second rotating rods are rotatably installed between the two opposing inner walls of the two defecation chambers, and the two first rotating rods are respectively fixedly connected to the corresponding sealing baffles.

[0016] Furthermore, a first gear is fixedly fitted onto the outer wall of each of the two first rotating rods, and a second gear that meshes with the corresponding first gear is fixedly fitted onto the outer wall of each of the two second rotating rods.

[0017] Furthermore, a U-shaped rod is fixedly installed at the bottom of each of the two foot pedals, and a rack that meshes with the second gear is fixedly connected to the other end of each of the two U-shaped rods.

[0018] Furthermore, each of the two foot pedals is vertically fixedly connected to a squeezing rod at its bottom, and each of the four squeezing rods is slidably fitted with a fixing cylinder at its bottom. Each of the four fixing cylinders is vertically fixedly installed on the squat toilet, and a spring is installed between each of the four squeezing rods and the corresponding inner cavity of the fixing cylinder.

[0019] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0020] 1. Automated opening and closing, conforming to toilet habits. When the user naturally steps on the foot pedal, the sealing barrier opens automatically; after using the toilet, the barrier closes automatically under the action of the spring when the foot leaves the foot pedal, without the need for manual operation, which conforms to human behavior.

[0021] 2. When the baffle is closed, it completely covers the defecation opening, effectively blocking the spread of odors. It uses a pure mechanical gear and rack transmission structure, which requires no electricity or sensors, reducing the failure rate and making it suitable for environments without power supply.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The present invention will be further described below with reference to the embodiments.

[0034] Example 1:

[0035] Reference Figure 1-5 This is the first embodiment of the present invention, which discloses a non-drainage portable toilet, including a toilet body 1 and a toilet cavity opened on the front of the toilet body 1. The opening of the toilet cavity is as shown in the attached instruction manual. Figure 3 As shown, steps are provided to facilitate users to climb to the bottom of the toilet chamber for toilet use. A toilet door 12 is rotatably installed at the opening of the toilet chamber. A collection chamber is opened on the back of the toilet body 1. A collection box 2 is detachably installed in the collection chamber and has an open top design. A squat toilet 3 is fixedly installed at the bottom of the toilet chamber and has a defecation chamber that is connected to the collection chamber through the top and bottom. An opening with the same specifications as the defecation chamber is opened between the top of the collection chamber and the toilet chamber.

[0036] Two sealing baffles 31 are rotatably installed at the upper opening of the defecation chamber. The end cross-section of the two sealing baffles 31 is semi-circular. Therefore, no matter which foot of the user leaves first, it will not affect the sealing performance of the end of the two sealing baffles 31. The top two sides of the squat toilet 3 are equipped with adjustable foot pedals 37. When the two foot pedals 37 are lowered, the two sealing baffles 31 rotate synchronously but in opposite directions. That is, they rotate at the same time, but one sealing baffle 31 rotates clockwise and the other sealing baffle 31 rotates counterclockwise. Since the user needs to leave the squat toilet 3 after using the toilet, the left and right feet will step out separately. That is to say, the two foot pedals 37 will not descend and return to rise synchronously, but the final descent amount is the same. The standard is that the bottom of the foot pedal 37 abuts against the top of the fixed cylinder 38. At this time, the squeezing rod 39 is fully inserted into the fixed cylinder 38.

[0037] Example 2:

[0038] Reference Figure 1-5 This is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: the two opposite outer walls of the toilet body 1 are provided with exhaust vents through the toilet cavity, and several grid plates 11 are installed obliquely in the two exhaust vents. The oblique design is intended to prevent rainwater from entering the toilet cavity. A door lock structure is installed between the toilet door 12 and the inner wall of the toilet cavity. The door lock structure is common knowledge in the technical field and will not be described in detail. A handle 21 is vertically fixed on the back of the collection box 2. Rollers 22 are installed at the four corners of the bottom of the collection box 2. The bottom of the collection cavity is provided with a groove to facilitate the rolling of the rollers 22.

[0039] Two first rotating rods 32 and two second rotating rods 34 are rotatably installed between the two opposing inner walls of the two defecation chambers. The two first rotating rods 32 are respectively fixedly connected to the corresponding sealing baffles 31. The outer rod walls of the two first rotating rods 32 are fixedly fitted with first gears 33, and the outer rod walls of the two second rotating rods 34 are fixedly fitted with second gears 35 that mesh with the corresponding first gears 33.

[0040] U-shaped rods 36 are fixedly installed at the bottom of both foot pedals 37. A U-shaped cavity is opened in the squat toilet 3 to facilitate the lifting and sliding of the U-shaped rods 36. The other end of each of the two U-shaped rods 36 is fixedly connected to a rack that meshes with the second gear 35. A groove is also opened in the squat toilet 3 to allow only the rack to lift and slide, ensuring that the rack and the second gear 35 are always in a meshing state. The bottom of each of the four squeezing rods 39 is slidably fitted with a fixed cylinder 38. The four fixed cylinders 38 are vertically fixed on the squat toilet 3. A spring 310 is installed between each of the four squeezing rods 39 and the corresponding fixed cylinder 38 cavity. The outer diameter of the squeezing rod 39 is the same as the inner diameter of the fixed cylinder 38 cavity, and the squeezing rod 39 is always slidably inserted into the corresponding fixed cylinder 38 cavity. The outer wall of the fixed cylinder 38 has an air inlet and outlet hole through the fixed cylinder 38 cavity to ensure that the pressure of the remaining space in the fixed cylinder 38 cavity is always the same as the outside air pressure, balancing the air pressure and preventing the spring movement from being obstructed.

[0041] The remaining structure is the same as that in Example 1.

[0042] This utility model's non-drainage portable toilet adopts a mechanical linkage structure, controlling the opening and closing of the sealing baffle 31 via the foot pedal 37 to achieve automated operation. The specific working process is as follows:

[0043] 1. Initial state (baffle closed)

[0044] Before using the toilet, the two sealing baffles 31 remain closed under the elastic force of the spring 310, completely covering the upper opening of the defecation chamber to prevent odor from overflowing. The foot pedal 37 is not stepped on and is in the initial high position. The rack connected to the U-shaped rod 36 is not engaged with the second gear 35, and the transmission mechanism is in the ready-to-trigger state.

[0045] 2. Toilet preparation (step on foot pedal 37, open sealing panel 31)

[0046] After the user enters the toilet chamber, they step on the foot pedals 37 on both sides of the squat toilet 3. The foot pedals 37 are subjected to downward pressure, which drives the U-shaped rod 36 at the bottom to move downward. The rack at the end of the U-shaped rod 36 descends and meshes with the second gear 35. The movement of the rack drives the second gear 35 to rotate, which in turn drives the second rotating rod 34 to rotate. Since the second gear 35 meshes with the first gear 33, the first gear 33 rotates in the opposite direction, causing the first rotating rod 32 to drive the sealing baffle 31 to flip outward. The opening of the defecation chamber gradually opens. During this process, the vertical movement of the foot pedals 37 is converted into the rotational movement of the sealing baffle 31 through the gear and rack mechanism, realizing the automatic opening of the defecation port.

[0047] 3. During toilet use (keep the partition open)

[0048] With the user keeping both feet on the foot pedal 37, the sealing baffle 31 remains open under the locking action of the gear transmission mechanism, allowing excrement to fall directly into the collection box 2 below through the defecation chamber. Since the top of the collection box 2 is designed to be open, excrement can enter smoothly, avoiding blockage or residue.

[0049] 4. Toileting is finished (release foot pedal 37, seal panel 31 closes)

[0050] After using the toilet, the user removes both feet from the foot pedal 37. The foot pedal 37 returns to its original position under the rebound force of the spring 310. The U-shaped rod 36 drives the rack to rise and disengage from the second gear 35. The sealing baffle 31 rotates in the opposite direction under the action of the first gear 33 and the first rotating rod 32, and closes the upper opening of the defecation chamber again. After the sealing baffle 31 is closed, the defecation chamber is completely sealed, effectively preventing the odor in the collection box 2 from spreading to the toilet chamber.

[0051] 5. Cleaning the collection box (removable and replaceable)

[0052] When the amount of excrement in the collection box 2 reaches a certain level, the maintenance personnel can pull the collection box 2 out of the collection chamber on the back of the toilet body 1 through the handle 21. Since the bottom of the collection box 2 is equipped with rollers 22, the movement process is labor-saving and convenient. After cleaning, the empty collection box 2 can be pushed back into the collection chamber for continued use.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
