Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a portable toilet with active exhaust. Background Technology

[0002] A portable toilet is a mobile and easy-to-carry sanitary facility designed specifically for outdoor environments. It solves the need for toileting in situations where there are no fixed sanitary facilities, such as in the wild, camping, or traveling.

[0003] Current mainstream portable toilets adopt a modular design, consisting of an upper chamber (toilet seat) and a lower chamber (sewage container) that are assembled together, with the lower chamber serving as the waste storage unit. While this design facilitates disassembly and cleaning, it suffers from the following technical bottlenecks.

[0004] Excrement decomposes and ferments within the sealed lower chamber, producing gases such as methane and hydrogen sulfide, creating positive pressure inside. When the user disassembles the chamber for cleaning, the compressed gas is released instantly, causing excrement to splash.

[0005] Therefore, improvements are needed. Utility Model Content

[0006] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing a portable toilet with active exhaust, thereby solving the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a portable toilet with active venting, comprising: a first housing, the first housing having a toilet bowl with a funnel-shaped recessed structure; a toilet seat, the toilet seat being hinged to one side of the first housing; a second housing, the second housing being detachably connected to the first housing, the second housing having a receiving space, the second housing communicating with the drain outlet of the toilet bowl; and a venting assembly, the venting assembly being disposed on the second housing, the venting assembly being driven to vent by external force pressing.

[0008] Furthermore, a recessed mounting area is provided at the edge of the upper surface of the second housing, and a limiting member is provided in the mounting area; the exhaust assembly includes an exhaust valve provided on the upper surface of the second housing, a drive button provided on the side of the second housing, a spring connected to the drive button, and a fixing member connected to the spring; the exhaust valve has an upwardly protruding movable contact, at least a portion of the drive button is exposed outside the limiting member, at least a portion of the drive button extends to the movable contact position, and the two ends of the spring are respectively connected to the drive button and the fixing member; wherein, when the drive button is pressed by external force, the drive button applies pressure to the movable contact to open the exhaust valve and exhaust air; when the external force is removed from the drive button, the spring drives the drive button to reset.

[0009] Furthermore, a first protrusion is provided on the inner side of the drive button, and one end of the spring is fitted onto the first protrusion; a second protrusion is provided on the side of the fixing member opposite to the drive button, and the other end of the spring is fitted onto the second protrusion.

[0010] Furthermore, the second housing includes a sewage pipe connected to the second housing, and the sewage pipe is rotatable relative to the second housing.

[0011] Furthermore, a rinsing port is provided on the side of the second housing, and a sealing cap is provided on the rinsing port, the sealing cap being threadedly connected to the rinsing port.

[0012] Further, a display component is included, which is disposed in the installation area. The display component includes a rocker arm hinged to the exhaust valve, a float connected to the lower end of the rocker arm, a first magnet disposed on the rocker arm, a second magnet disposed on the side of the second housing, and a color indicator sleeved on the second magnet. The rocker arm, the float, and the first magnet are disposed in the second housing. A groove is provided on the side of the second housing in the installation area. The second magnet and the color indicator are placed in the groove. The second magnet and the first magnet are disposed opposite each other. A transparent element is provided along the direction of the groove in the limiting member. The float moves upward due to the buoyancy of the excrement in the second housing, causing the rocker arm to rotate. The first magnet attracts the second magnet to move along the groove to the transparent element. The color indicator displays a color on the transparent element.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Optimized exhaust mechanism: By setting an exhaust component driven by external force, the accumulated gas inside is actively released before the second chamber is disassembled, effectively avoiding the problem of excrement splashing due to positive pressure. A linkage mechanism of drive button-spring-fixed component, in conjunction with the moving contact of the exhaust valve, achieves precise exhaust when pressed and automatic reset after force is released, ensuring the controllability and stability of the exhaust process.

[0015] Visualized structure: Through the linkage structure of float-swing rod-magnet, combined with the cooperation of color indicator and transparent parts, the changes in the liquid level of excrement in the second tank are converted into color display, realizing intuitive liquid level monitoring function, improving safety of use, and facilitating timely cleaning; at the same time, the structure is simple and the manufacturing cost is low.

"Below," "below," and "under" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In view of the technical problems described in the background art, such as Figure 1-9As shown, a portable toilet with active venting is provided, comprising: a first housing 1, the first housing 1 having a chamber pot 2 with a funnel-shaped recessed structure; a toilet seat 3, the toilet seat 3 being hinged to one side of the first housing 1; a second housing 4, the second housing 4 being detachably connected to the first housing 1, the second housing 4 having a receiving space inside, the second housing 4 communicating with the drain outlet of the chamber pot 2; and a venting assembly 5, the venting assembly 5 being disposed on the second housing 4, the venting assembly 5 being driven to vent by external force pressing.

[0029] In the above technical solution, the first container 1 and the second container 4 can be used by means of a snap fastener on the side. The toilet bowl 2 on the first container 1 is connected to the excrement inlet of the second container 4. Preferably, the excrement outlet of the toilet bowl 2 is located in the middle of the first container 1, and the excrement inlet of the second container 4 is also located in the middle.

[0030] By installing an exhaust assembly 5 on the second chamber 4, which is used by the user to actively press to release the gas from the second chamber 4, it is possible to avoid the second chamber 4 being in a closed state for a long time and then suddenly opening it directly, which would cause the excrement to splash.

[0031] The second housing 4 has a recessed mounting area 6 at the edge of its upper surface, and a limiting member 7 is provided in the mounting area 6. The exhaust assembly 5 includes an exhaust valve 8 on the upper surface of the second housing 4, a drive button 9 on the side of the second housing 4, a spring 10 connected to the drive button 9, and a fixing member 11 connected to the spring 10. The exhaust valve 8 has an upwardly protruding movable contact 12. At least a portion of the drive button 9 is exposed outside the limiting member 7, and at least a portion of the drive button 9 extends to the position of the movable contact 12. The two ends of the spring 10 are respectively connected to the drive button 9 and the fixing member 11. When the drive button 9 is pressed by an external force, the drive button 9 presses down to the movable contact 12 to open the exhaust valve 8 and exhaust air. When the external force is removed from the drive button 9, the spring 10 drives the drive button 9 to return to its original position.

[0032] The above provides an implementable exhaust structure. Specifically, an installation area 6 is provided on the second housing 4, extending to both the upper surface and the side surface of the second housing 4. A limiting member 7 is provided on the installation area 6, designed to fit the installation area 6 and limiting the drive button 9 so that it moves toward the movable contact 12 of the exhaust valve 8. The exhaust valve 8 is installed inside the second housing 4, and the movable contact 12 is located on the upper surface of the second housing 4. The movable contact 12 acts as the switch for the exhaust valve 8. When the movable contact 12 is pressed, gas is discharged from the second housing 4; when the movable contact 12 is reset, the second housing 4 is closed. The drive button 9 is an elongated structure located outside the second housing 4. The drive button 9 is connected to a fixing member 11 via a spring 10, and the fixing member 11 is fixedly installed on the side surface of the second housing 4.

[0033] In actual use, the user presses the drive button 9, which applies pressure to the active contact 12, causing the exhaust valve 8 to open and release the accumulated gas in the second chamber 4; after the external force is removed, the spring 10 drives the drive button 9 to reset, and the exhaust valve 8 closes.

[0034] In the above structure, by setting an exhaust assembly 5 driven by external force, the accumulated gas inside is actively released before the second housing 4 is disassembled, effectively avoiding the problem of excrement splashing due to positive pressure. The linkage mechanism of drive button 9-spring 10-fixed part 11, together with the moving contact 12 of exhaust valve 8, realizes the function of precise expulsion when pressed and automatic reset after the force is released, ensuring the controllability and stability of the exhaust process.

[0035] Specifically, a first protrusion 13 is provided on the inner side of the drive button 9, and one end of the spring 10 is fitted onto the first protrusion 13; a second protrusion 14 is provided on the side of the fixing member 11 opposite to the drive button 9, and the other end of the spring 10 is fitted onto the second protrusion 14.

[0036] During installation, the two ends of the spring 10 are respectively engaged and fixed with the first protrusion 13 and the second protrusion 14 to install the spring 10 and ensure the elastic function of the spring 10.

[0037] The second housing 4 includes a sewage pipe 15, which is connected to the second housing 4 and is rotatable relative to the second housing 4.

[0038] The sewage pipe 15 is used to empty the excrement in the second box 4. When in use, simply connect the sewage pipe 15 to the external pipe and pour it out.

[0039] Specifically, the second housing 4 has a rinsing port on its side, and a sealing cover 16 is provided on the rinsing port, which is threadedly connected to the rinsing port.

[0040] The waste inside the second tank 4 is rinsed with clean water through the rinsing port. At the same time, when cleaning is not required, it is sealed by connecting the sealing cover 16.

[0041] This utility model also includes a display component, which is disposed in the installation area 6. The display component includes a swing arm 17 hinged to the exhaust valve 8, a float 18 connected to the lower end of the swing arm 17, a first magnet 19 disposed on the swing arm 17, a second magnet 20 disposed on the side of the second housing 4, and a color indicator 21 sleeved on the second magnet 20. The swing arm 17, the float 18, and the first magnet 19 are disposed inside the second housing 4. The second housing 4 is provided with a slide groove 23 on the side of the installation area 6. The second magnet 20 and the color indicator 21 are placed in the slide groove 23. The second magnet 20 and the first magnet 19 are disposed opposite each other. The limiting member 7 is provided with a transparent member 22 along the direction of the slide groove 23. The float 18 moves upward due to the buoyancy of the excrement in the second housing 4, causing the swing arm 17 to rotate. The first magnet 19 attracts the second magnet 20 to move along the slide groove 23 to the transparent member 22. The color indicator 21 displays a color on the transparent member 22.

[0042] Since existing portable toilets cannot determine the amount of excrement inside the container, further technical improvements are needed.

[0043] The specific solution is as follows: the swing arm 17 is hinged to the lower end of the exhaust valve 8, ensuring that the swing arm 17 can rotate freely without affecting the function of the exhaust valve 8; the float 18 is connected to the lower end of the swing arm 17, ensuring that the float 18 can move up and down with the change of the liquid level of the excrement; the first magnet 19 is set on the swing arm 17, and the second magnet 20 and the color indicator 21 are sleeved in the slide groove 23, ensuring that the second magnet 20 is set opposite to the first magnet 19; a transparent part 22 is set on the limiting part 7 along the direction of the slide groove 23 so as to observe the color indicator 21.

[0044] When the level of excrement in the second tank 4 rises, the float 18 moves upward under the action of buoyancy, causing the swing arm 17 to rotate. The first magnet 19 on the swing arm 17 attracts the second magnet 20 to move along the slide 23 to the position of the transparent part 22, and the color indicator 21 displays the color. Preferably, the transparent part 22 is transparent, and the color indicator 21 is colored, such as red. When the user can see red through the transparent part 22, it prompts the user to clean the second tank 4 in time.

[0045] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
