Description

Technical Field

[0001] This invention belongs to the technical field of biodegradation treatment devices, and in particular relates to a biodegradation treatment device for domestic sewage containing feces with an opening and closing baffle. Background Technology

[0002] A biodegradation treatment device is a device that uses special strains of bacteria mixed with biological carriers such as sawdust and stirred to degrade domestic sewage such as feces.

[0003] The prior art, such as CN215436833U, discloses a marine waterless self-degrading toilet, including a shell, a partition, a toilet seat ring, and a toilet cover; characterized in that it also has components such as a power cord inlet, an exhaust port, a switch cover, a control box cover, a toilet cover opening sensor, a working indicator light, a dehumidification button, an exhaust fan, a motor reducer, an electrical control module, a biodegradation tank, a stirring shaft, stirring blades, a temperature and humidity sensor, thermal insulation cotton, and an electric heating element.

[0004] According to feedback from numerous crew members, the aforementioned existing technology causes users to see the mixing blades and the mixture of feces and bacteria carriers inside the liner as soon as they open the lid. Seeing the mixing blades makes them worry about being scraped, and seeing the mixture makes them feel disgusted and disgusted, thus affecting their mental state.

[0005] like Figure 9 A horizontal insert plate 35 is located below the toilet's discharge compartment 35. The insert plate 35 has a certain space to accommodate human excrement. Below the insert plate 35 is the toilet mixing chamber 8. When the user opens the toilet lid, the insert plate extends, blocking the entrance of the discharge compartment 35 into the toilet mixing chamber 8. The user cannot see the mixing shaft and the fecal mixture inside the toilet mixing chamber 8. The user directly discharges the feces onto this insert plate 35. After the user leaves and closes the toilet lid, the insert plate 35 moves backward and retracts into the toilet shell 11. The feces are blocked by the side wall of the toilet mixing chamber 8 and fall into the toilet mixing chamber 8 below. Then the insert plate 35 extends again, blocking the entrance of the toilet mixing chamber 8, waiting for the next user.

[0006] Although this design prevents users from directly seeing the mixing shaft and the mixture of feces inside the hopper, there will be scraping residue of feces on the top of the baffle plate, which is easy to dry and harden on. Over time, it will form a very smelly layer of filth, which will not only emit odors but also breed bacteria, seriously affecting the appearance and environment. Summary of the Invention

[0019] The opening and closing assembly consists of two baffle rotating shafts, two opening and closing baffles, a right-hand rotating shaft swing arm, a swing arm linkage pin, a block to be attracted, an electromagnet, an electromagnet fixing fork, a left-hand rotating shaft swing arm, an electric push rod, and a control system.

[0020] Two baffle rotating shafts are arranged in parallel and are located on the left and right sides of the opening of the toilet mixing chamber, respectively. The two baffle rotating shafts are connected to the toilet mixing chamber shell through shaft support seats. The two opening and closing baffles are fixed on the corresponding baffle rotating shafts.

[0022] A pressure sensor switch is installed below the toilet seat. When the pressure on the pressure sensor switch exceeds the weight of the toilet seat, the pressure sensor switch controls the electric push rod to retract to its shortest state through the control system. When the pressure on the pressure sensor switch does not exceed the weight of the toilet seat, the pressure sensor switch controls the electric push rod to extend to its longest state through the control system.

[0023] The above-described biodegradation treatment device for fecal domestic sewage with an opening and closing baffle is characterized in that: the opening and closing baffle mechanism is composed of an opening and closing component;

[0035] 4. This invention adopts a dual-shaft structure, which, compared with a single-shaft structure, can increase the effective volume of the biodegradation chamber at the same height, thereby improving the processing capacity. At the same time, by reducing the length of the stirring blades, the height of the entire device can be reduced, making it suitable for human use. It can also solve the problem of uneven material surface in single-shaft structures. In addition, it can reduce the stirring dead corners and prevent material from clumping.

[0036] 5. In the event of a power outage, the opening and closing baffle can be opened using the weight of the baffle structure itself, and the device can still be used normally. Attached Figure Description

[0047] like Figures 1 to 4 A biodegradation treatment device for domestic sewage containing feces with an opening and closing baffle, comprising a toilet shell 11 and a toilet seat 1, wherein a toilet stirring chamber 8 is provided inside the toilet shell 11, and the toilet seat 1 is hinged above the toilet stirring chamber 8, characterized in that: a right stirring shaft 9 and a left stirring shaft 10 are provided inside the toilet stirring chamber 8, and two opening and closing components are provided at the opening of the toilet stirring chamber 8, one opening and closing component being located on the left side of the opening of the toilet stirring chamber 8, and the other opening and closing component being located on the right side of the opening of the toilet stirring chamber 8;

[0048] The opening and closing assembly on the left side consists of a top pin 2, a top pin spring seat 3, a baffle rotating shaft 4, a top pin return spring 5, a left rotating arm 61, an opening and closing baffle 7, a left baffle return spring 12, and two left baffle rotating shaft supports 15.

[0049] Both ends of the baffle rotating shaft 4 are hinged to the baffle rotating shaft support. The baffle rotating shaft support is fixedly connected to the toilet shell 11. The opening and closing baffle 7 is pivotally connected to the baffle rotating shaft 4. The left baffle return spring 12 is located on the left side of the opening and closing baffle 7 and can push the opening and closing baffle 7 to rotate counterclockwise. The upper end of the left rotating arm 61 is fixedly connected to the baffle rotating shaft 4. The left rotating arm 61 is located on the right side of the opening and closing baffle 7, and the left rotating arm 61 and the opening and closing baffle 7 form an angle. The top pin spring seat 3 is fixed on the left side of the opening of the toilet mixing chamber 8 shell. The top pin 2 and the top pin return spring 5 are located inside the top pin spring seat 3. The top pin return spring 5 is used to control the up and down movement of the top pin 2. The lower end of the top pin 2 is in contact with the right side of the left rotating arm 61.

[0050] The opening and closing assembly on the right side consists of a top pin 2, a top pin spring seat 3, a baffle rotating shaft 4, a top pin return spring 5, a right rotating arm 6, an opening and closing baffle 7, a right baffle return spring 13, and two right baffle rotating shaft supports 14.

[0051] Both ends of the baffle rotating shaft 4 are hinged to the baffle rotating shaft support. The baffle rotating shaft support is fixedly connected to the toilet shell 11. The opening and closing baffle 7 is pivotally connected to the baffle rotating shaft 4. The right baffle return spring 13 is located on the right side of the opening and closing baffle 7 and can push the opening and closing baffle 7 to rotate clockwise. The upper end of the right rotating arm 6 is fixedly connected to the opening and closing baffle 7. The right rotating arm 6 is located on the left side of the opening and closing baffle 7, and the right rotating arm 6 and the opening and closing baffle 7 form an angle. The top pin spring seat 3 is fixed on the right side of the opening of the toilet mixing chamber 8. The top pin 2 and the top pin return spring 5 are located inside the top pin spring seat 3. The top pin return spring 5 is used to control the up and down movement of the top pin 2. The lower end of the top pin 2 is in contact with the left side of the right rotating arm 6.

[0052] When the top pin 2 of the left opening and closing assembly and the top pin 2 of the right opening and closing assembly are not subjected to downward pressure, the lower ends of the left opening and closing baffle 7 and the right opening and closing baffle 7 close into a V-shape due to the thrust generated by the rebound of the left baffle return spring 12 and the right baffle return spring 13.

[0053] The two opening and closing baffles 7 are located above the right stirring shaft 9 and the left stirring shaft 10. When the toilet seat 1 is placed on the two top pins 2, the left opening and closing baffle 7 and the right opening and closing baffle 7 are in the closed state.

[0054] Working principle: When no one is sitting on the toilet seat 1, the toilet seat 1 rests on the top of the top pin 2 under its own weight. The top pin 2 does not move downward under the elastic support of the top pin return spring 5. At this time, the lower end of the top pin 2 is at its highest position. The right rotating arm 6 and the left rotating arm 61 do not rotate under the action of the left baffle return spring 12 and the right baffle return spring 13. The left baffle return spring 12 and the right baffle return spring 13 respectively support the corresponding opening and closing baffles 7. The two opening and closing baffles 7 close to form a closed V-shape. When viewed from above, the line of sight will be blocked by the opening and closing baffles. The partition blocks the view of the right and left stirring shafts 9 and the materials in the hopper. If a man needs to urinate, he can remove the toilet seat 1. The top pin 2 will not move, and the two opening and closing baffles 7 will remain closed in a V-shape. The urine will flow into the lower hopper through the gaps along the edges of the two baffles and the gaps on the front and back sides. Even if the urine hits the opening and closing baffles 7, it will not splash outside the toilet seat because the opening and closing baffles 7 are at an angle. The user will never be able to see the stirring shafts and materials in the hopper, thus blocking the view and preventing adverse physiological reactions.

[0055] When a user wants to defecate, they sit on the toilet seat 1. The user's weight acts on the toilet seat 1, causing it to press against the upper ends of the two top pins 2. The pressure on the two top pins 2 overcomes the elastic force of the pin return springs and moves downwards. The lower ends of the two top pins 2 also move downwards, thus pushing the corresponding left rotating arm 61 to rotate clockwise and the right rotating arm 6 to rotate counterclockwise. This causes the left opening / closing baffle 7 to rotate clockwise and the right opening / closing baffle 7 to rotate counterclockwise. When the toilet seat 1 contacts the toilet outer shell 11, the two opening / closing baffles... When plate 7 stops rotating, the opening and closing baffle 7 is in a vertical position. At this time, all the large toilet bowls will fall into the lower storage compartment. When the user gets up, the toilet seat 1 loses the pressure from the human body. Under the action of the return springs 5 ​​corresponding to the two top pins 2, the toilet seat 1 is lifted up. The left rotating arm 61 and the right rotating arm 6 lose the pressure from the lower end of the top pin 2. The left baffle return spring 12 and the right baffle return spring 13 respectively cause the corresponding opening and closing baffles 7 to spring back to the two pieces closed into a V-shape, thus restoring the function of blocking the view. Example 2

[0056] like Figures 5 to 6 and refer to Figure 1 and Figure 4 A biodegradation treatment device for domestic sewage containing feces with an opening and closing baffle, comprising a toilet shell 11 and a toilet seat 1, wherein a toilet stirring chamber 8 is provided inside the toilet shell 11, and the toilet seat 1 is hinged to the upper part of the toilet stirring chamber 8 shell, characterized in that: a right stirring shaft 9 and a left stirring shaft 10 are provided inside the toilet stirring chamber 8, and an opening and closing component is provided at the opening of the toilet stirring chamber 8.

[0057] The opening and closing assembly consists of two baffle rotating shafts 4, two opening and closing baffles 7, a right-hand rotating shaft swing arm 19, a swing arm linkage pin 20, a block to be attracted 21, an electromagnet 22, an electromagnet fixing fork 23, a left-hand rotating shaft swing arm 24, an electric push rod 25, and a control system.

[0058] Two baffle rotating shafts 4 are arranged in parallel and are located on the left and right sides of the opening of the toilet mixing chamber 8, respectively. The two baffle rotating shafts 4 are connected to the toilet mixing chamber 8 shell through the shaft support seat 18. The two opening and closing baffles 7 are fixed on the corresponding baffle rotating shafts 4. One end of the left rotating shaft swing arm 24 is fixed to the left baffle rotating shaft 4. The left rotating shaft swing arm 24 is provided with a first long hole. One end of the right rotating shaft swing arm 19 is fixed to the right baffle rotating shaft 4. The right rotating shaft swing arm 19 is provided with a second long hole. The swing arm linkage pin 20 passes through the first long hole and the second long hole at the same time. The swing arm linkage pin 20 is fixed to the iron block 21 to be attracted. The bottom of the electric push rod 25 is fixed to the toilet shell 11. The electromagnet fixing fork 23 is fixed to the top of the telescopic rod of the electric push rod 25. The electromagnet 22 is fixed to the electromagnet fixing fork 23.

[0059] When the electric push rod 25 is not energized, its telescopic rod is in a retracted state. The iron block 21 to be attracted moves downward to the lowest point under its own gravity. At this time, the two opening and closing baffles 7 are in an open state. When the electromagnet 22 is energized, it will attract the iron block 21 to be attracted. When the electric push rod 25 is energized and the telescopic rod extends to its maximum extension length, the right rotating shaft arm 19 and the left rotating shaft arm 24 are in a straight line. The two opening and closing baffles 7 close. The maximum extension length of the telescopic rod of the electric push rod 25 is the same as the distance between the position of the iron block 21 to be attracted when it rises from the lowest point to the position of the iron block 21 when the right rotating shaft arm 19 and the left rotating shaft arm 24 are in a straight line. The two opening and closing baffles 7 are located above the right stirring shaft 9 and the left stirring shaft 10.

[0060] A pressure sensor switch is provided below the toilet seat 1. When the pressure on the pressure sensor switch exceeds the weight of the toilet seat 1, the pressure sensor switch sends a signal to the control system, and the control system controls the electric push rod 25 to retract to its shortest state. When the pressure on the pressure sensor switch does not exceed the weight of the toilet seat 1, the pressure sensor switch sends a signal to the control system, and the control system controls the electric push rod 25 to extend to its longest state.

[0061] Working principle: When the electric push rod 25 and electromagnet 22 are energized, the electromagnet 22 attracts the iron block 21 to be attracted. When the electric push rod 25 is activated, the telescopic rod of the electric push rod 25 is extended. The telescopic rod of the electric push rod 25 drives the swing arm linkage pin 20 on the iron block 21 to move upward. The swing arm linkage pin 20 drives the right rotating shaft swing arm 19 and the left rotating shaft swing arm 24 to rotate. When the right rotating shaft swing arm 19 and the left rotating shaft swing arm 24 are in the same straight line, the two opening and closing baffles 7 close, and the user's line of sight will be blocked, and the stirring shaft and other conditions in the material bin cannot be seen.

[0062] When a user wants to defecate, they sit on the toilet seat 1. Since their body weight exceeds the weight of the toilet seat 1, the pressure sensor sends a signal to the control system. The control system then controls the electric push rod 25 to retract to its shortest position. At this time, the swing arm linkage pin 20 on the magnetic block 21 is at its lowest position, and the two opening and closing baffles 7 open. The expelled feces naturally fall into the lower storage compartment. When the user stands up, the toilet seat 1 loses the pressure from the body, and the pressure on the pressure sensor does not exceed the weight of the toilet seat 1. A signal is sent to the control system, which controls the electric push rod 25 to extend to its longest position. At this time, the swing arm linkage pin 20 on the magnet block 21 is at its highest position, and the two opening and closing baffles 7 are closed. The user's view will be blocked, and the stirring shaft and other objects in the material bin will not be visible. If a man needs to urinate, he can remove the toilet seat 1. The two opening and closing baffles 7 will still be closed, and the urine will flow into the lower material bin from the gaps along the edges of the two baffles. The user will never be able to see the stirring shaft and other objects in the material bin, thus blocking the view and preventing adverse physiological reactions.

[0063] In this invention, even when the toilet is not powered, the magnet 21 will move downwards to the lowest point under its own gravity, so that the two opening and closing baffles 7 are in the open state, which can meet the user's needs. Example 3

[0064] like Figures 7 to 8 and refer to Figure 1 and Figure 4 A biodegradation treatment device for domestic sewage containing feces with an opening and closing baffle, comprising a toilet shell 11 and a toilet seat 1, wherein a toilet stirring chamber 8 is provided inside the toilet shell 11, and the toilet seat 1 is hinged above the toilet stirring chamber 8, characterized in that: a right stirring shaft 9 and a left stirring shaft 10 are provided inside the toilet stirring chamber 8, and an opening and closing component is provided at the opening of the toilet stirring chamber 8.

[0065] The opening and closing assembly consists of two baffle rotating shafts 4, two opening and closing baffles 7, a motor mounting bracket 26, a left sector meshing gear 27, a right sector meshing gear 28, a baffle closing induction switch 29, a baffle fully open induction switch 30, a coupling 31, a motor 32, a shaft position sensing plate 33, and a control system for controlling the rotation direction of the motor 32 shaft.

[0066] Two baffle rotating shafts 4 are arranged in parallel and are located on the left and right sides of the opening of the toilet mixing chamber 8, respectively. The two baffle rotating shafts 4 are connected to the housing of the toilet mixing chamber 8 through the shaft support seat 18. Two opening and closing baffles 7 are fixed on the corresponding baffle rotating shafts 4. The right sector meshing gear 28 is fixed to the right baffle rotating shaft 4, and the left sector meshing gear 27 is fixed to the left baffle rotating shaft 4. The left sector meshing gear 27 and the right sector meshing gear 28 mesh with each other. The motor mounting bracket 26 is fixed to the toilet housing 11. The motor 32 is fixed on the motor mounting bracket 26. The output shaft of the motor 32 is connected to the right baffle rotating shaft 4 through the coupling 31. The rotating shaft position sensing plate 33 is fixed on the right baffle rotating shaft 4 between the coupling 31 and the right sector meshing gear 28. The baffle closing sensing switch 29 and the baffle fully opening sensing switch 30 are fixed on the motor mounting bracket 26. The baffle closing sensing switch 29 is located above the fully opening sensing switch 30.

[0067] A pressure sensor switch is provided below the toilet seat 1, and two opening and closing baffles 7 are located above the right stirring shaft 9 and the left stirring shaft 10.

[0068] Working principle: When a user sits on the toilet seat 1 to defecate, the pressure sensor switch receives pressure exceeding the weight of the toilet seat 1. The pressure sensor switch sends a signal to the control system, which then controls the motor 32 to rotate counter-clockwise. At this time, the right sector gear 28 rotates counter-clockwise, and the left sector gear 27 rotates clockwise. When both opening / closing baffles 7 are fully open, the position sensor 33, which follows the rotation of the shaft, is detected by the baffle-fully-open sensor switch 30, which sends a baffle-fully-open signal. The control system immediately stops the motor. When the user leaves the toilet seat 1, the pressure sensor switch sends a signal to the control system, which then controls the motor 32 to rotate clockwise. At this time, the right sector gear 28 rotates clockwise. The left sector gear 27 rotates counterclockwise until the two opening and closing baffles 7 close together. When the two opening and closing baffles 7 are completely closed, the position sensor 33 of the rotating shaft is sensed by the baffle closure sensor switch 29 and sends a signal to the control system. The control system controls the motor 32 to stop rotating, and the two opening and closing baffles 7 remain closed. At this time, the user's view is blocked, and the stirring shaft and other objects in the material bin cannot be seen. If a man needs to urinate at this time, he can remove the toilet seat 1. The two opening and closing baffles 7 will still be closed, and the urine will flow into the lower material bin from the gaps along the edges of the two baffles. The user will never be able to see the stirring shaft and other objects in the material bin, thus blocking the view and preventing adverse physiological reactions.

[0069] The above-described biodegradation treatment device for fecal domestic sewage with an opening and closing baffle is characterized in that: the opening and closing component is powered by both a battery or energy storage capacitor and the power grid.

[0070] The above-described embodiment of a biodegradation treatment device for fecal domestic sewage with an opening and closing baffle is characterized in that: the opening and closing baffle 7 is coated with a non-stick urine coating.

[0071] The present invention has the following beneficial effects:

[0072] 1. This invention is applicable to waterless biodegradable toilets or waterless toilets.

[0073] 2. Embodiment 1 of the present invention is fully mechanical and can still be used in the event of a power outage.

[0074] 3. This invention significantly improves the user experience, making this energy-saving and environmentally friendly biodegradation treatment device for fecal wastewater more readily accepted by a wider range of people, thus promoting its widespread use and bringing considerable economic benefits to society.

[0075] 4. This invention adopts a dual-shaft structure, which, compared with a single-shaft structure, can increase the effective volume of the biodegradable chamber at the same height, thereby improving the processing capacity. At the same time, by reducing the length of the stirring blades, the height of the entire device can be reduced, making it suitable for human use. It can also solve the problem of uneven material surface in a single-shaft structure. In addition, it can reduce the stirring dead zone and prevent material from clumping.

[0076] 5. In the power-off state, the opening and closing baffle can be opened by the gravity of the opening and closing baffle structure itself, and it can still be used normally.

[0077] 6. In the case of a power outage, Embodiment 3 of the present invention can utilize the electrical energy of a battery or energy storage capacitor to immediately control the motor to rotate and open the opening and closing baffle when the power grid is interrupted, ensuring normal operation even after a power outage.

[0078] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
