Description

Technical Field

[0001] The present invention relates to the field of environmentally friendly toilets, and in particular to household water-free intelligent environmentally friendly toilets. Background Art

The sliding plate 302 is provided with a clamping block slot 307; the upper end of the clamping block 303 is locked in the clamping block slot 307. A sealing ring is installed along the upper edge of the sliding plate 302.

[0034] The function of the sealing device is to ensure that the upper portion of the discharge port 2 is sealed to ensure that the malodorous gas generated in the fermentation bin 4 is discharged through the exhaust port 5.

[0035] Among them, such as Figure 7 and Figure 8As shown, the stirring device includes a first drive shaft 406 and a second drive shaft 405; a plurality of stirring paddles 407 are staggered on both sides of the first drive shaft 406 and the second drive shaft 405, and an auxiliary stirring paddle 408 is installed between the stirring paddles 407; the stirring paddle 407 includes a first support and a second support; one end of the auxiliary stirring paddle 408 is connected to the front end of the first support, and the other end of the auxiliary stirring paddle 408 is connected to the rear end of the second support, so that the auxiliary stirring paddle 408 is inclined between the first support and the second support. The first drive shaft 406 and the second drive shaft 405 pass through the fermentation chamber 4 and extend to the outer end of the fermentation chamber 4, and are respectively equipped with a first gear 401 and a second gear 402; the first gear 401 and the second gear 402 are meshed; each of the first gear 401 and the second gear 402 is connected to the outside of the drive motor 403; the angle between the stirring paddle 407 on the first drive shaft 406 and the stirring paddle 407 on the second drive shaft 405 is 90 degrees. Gear grooves are provided on both end faces of the first gear 401; the gear grooves are fan-shaped structures, and multiple gear grooves are evenly distributed around the geometric center of the first gear 401 as the axis; gear grooves are provided on both end faces of the second gear 402; the gear grooves are fan-shaped structures, and multiple gear grooves are evenly distributed around the geometric center of the second gear 402 as the axis.

[0036] Through the effective design of the stirring device, while ensuring the effective mixing of the inoculum and feces, the load on the drive motor is reduced, the structural design of transmission components such as gears is further optimized, the material weight is reduced, and the long-term stable low-load operation of the equipment is ensured.

[0037] Among them, such as Figure 1 and Figure 10 As shown, the ventilation and exhaust device includes an exhaust fan 601 and a ventilation groove 605; the exhaust fan 601 is located on one side of the fermentation bin 4; the ventilation groove 605 is located at the bottom of the fermentation bin 4; an exhaust baffle 603 is provided above the ventilation groove 605; the exhaust baffle 603 is in an inverted "V" shape, and a baffle outlet 604 is provided between the exhaust baffle 603 and the ventilation groove 605; an exhaust duct 602 is installed on the exhaust fan 601; a heater is provided in the exhaust duct 602; the exhaust duct 602 is connected to the ventilation groove 605; and a temperature and humidity sensor is provided in the fermentation bin 4. The ventilation groove 605 runs through the bottom of the fermentation bin 4, and the exhaust baffle 603 completely covers the ventilation groove 605; a plurality of baffle outlets 604 are provided and evenly distributed between the exhaust baffle 603 and the ventilation groove 605.

[0038] Further, such as Figure 10As shown, the bottom of the fermentation bin 4 is symmetrically provided with two arc-shaped grooves; the ventilation groove 605 is located in the middle of the two arc-shaped grooves; and the exhaust baffle 603 is located above the two arc-shaped grooves 403.

[0039] The exhaust baffle 603 is designed in an inverted "V" shape and completely covers the top of the ventilation groove 605, ensuring that the material in the fermentation bin 4 will not enter the ventilation groove 605 to avoid blockage.

[0040] Based on real-time monitoring of the temperature and humidity within fermentation chamber 4 by the temperature and humidity sensor, when heating and ventilation are required, exhaust fan 601 and the PTC heater within exhaust duct 602 are activated, blowing hot air into fermentation chamber 4 through ventilation groove 605 and baffle outlet 604 to raise the temperature and reduce the humidity within fermentation chamber 4. Since this process may produce malodorous gases due to volatilization, the pressurized action of exhaust fan 601 further dissipates the malodorous gases through the gap between fermentation chamber opening 401 and discharge port 2. Finally, exhaust port 5 and the corresponding hose are used to expel the malodorous gases to the exterior of housing 1.

[0041] While the exhaust fan 601 is running, the baffle outlet 604 continuously discharges air, and the stirring shaft 402 in the arc groove 403 is also running continuously to improve the mixing effect of the bacterial agent and feces, while also avoiding the problem of blockage of the baffle outlet 604 during the stirring process.

[0042] Among them, such as Figure 1 and Figure 9 As shown, a rear cover body 11 is provided above the shell 1; a seat cushion 13 is provided in front of the rear cover body 11; the seat cushion 13 is located above the excretion port 2; a cover plate 12 is provided above the seat cushion 13; the cover plate 12 is hinged to the rear cover body 11; a magnet 7 is provided on the cover plate 12 at the hinge between the cover plate 12 and the rear cover body 11; a Hall switch 8 is provided in the rear cover body 11; when the cover plate 12 is fully opened, the magnet 7 and the Hall switch 8 are connected to generate a signal.

[0043] Its working principle is:

[0044] According to the opening or closing of the Hall switch, a corresponding on-off signal is sent to the sliding plate drive motor 306. When the cover 12 is opened, the Hall switch 8 sends a signal, and the sliding plate drive motor 306 starts to move, causing the sliding plate 302 to move open, completely exposing the top of the discharge port 2 to ensure normal use by personnel.

[0045] During the above process, the driving motor 403, the exhaust fan 601 and the heater in the exhaust duct 602 are all in a power-off state to ensure that people can use the toilet normally.

[0046] When the cover plate 12 is closed, the Hall switch 8 sends a signal, and the sliding plate driving motor 306 starts to move, so that the sliding plate 302 moves and closes, and the top of the discharge port 2 is completely sealed.

[0047] During the above process, the driving motor 403, the exhaust fan 601 and the heater in the exhaust duct 602 start to operate.

[0048] Furthermore, it is preferred that 10 seconds after the cover 12 is closed, the drive motor 403 starts to rotate and the exhaust fan 601 starts synchronously. The drive motor 403 and the exhaust fan 601 run for 2 minutes.

[0049] The heater in the exhaust duct 602 is preferably a PTC heater; wherein, a temperature sensor is provided in the fermentation bin 4. When the overall temperature in the fermentation bin 4 is lower than 10 degrees Celsius, the PTC heater and the exhaust fan 601 are started, and when the overall temperature in the fermentation bin 4 is higher than 20 degrees Celsius, the PTC heater is stopped.

[0050] Furthermore, the number of people using the toilet can be counted based on the number of switches and closures of the Hall switch 8 .

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
