Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection toilets, and more specifically, to a squatting device and an environmental protection toilet. Background Art

[0002] With the development of society, the concept of green environmental protection has gradually been taken seriously by the Chinese people. Toileting is a problem that everyone has to face every day, and there is great potential for developing green environmental protection in the area of toileting.

[0003] Currently, the most recognized green environmental protection toilet is the environmental protection toilet based on biological treatment. Its core technology is to set up a biochemical reaction chamber, where biological fillers are regularly supplemented. The feces entering the biochemical reaction chamber are degraded by microorganisms. During the reaction process, various pathogenic bacteria can be eliminated and organic fertilizers can be produced, and water is not required, which is particularly suitable for application in areas with water supply difficulties or temporarily erected meeting places.

[0004] However, the current environmental protection toilets based on biological treatment have the following problems:

[0005] Since water is not required during normal use, the surface of such environmental protection toilets is generally specially treated so that feces will slide down automatically when they fall onto the squatting pan and fall into the biochemical reaction chamber through its sewage outlet. Since the feces directly fall below the sewage outlet, if the feces are not decomposed in time, the feces will accumulate seriously below the sewage outlet. When a user enters the environmental protection toilet, there is a high possibility that the user will look down at the sewage outlet, and in this way, the user will directly see the feces below the sewage outlet through the sewage outlet, which will make the user feel disgusted and thus not want to use the environmental protection toilet; at the same time, the gas in the biochemical reaction chamber is easily transmitted to the space of the environmental protection toilet through the sewage outlet, making the smell in the environmental protection toilet unpleasant and the utilization rate of the environmental protection toilet low.

[0006] In addition, since the feces directly fall below the sewage outlet, the feces will accumulate in the same place, which makes the feces accumulated at a higher position unable to come into full contact with the biological fillers, and the time required for complete decomposition is relatively long, resulting in the actual load of the biochemical reaction chamber not reaching the expected value and affecting the normal use of the environmental protection toilet. For this reason, the prior art generally sets an electric spreading mechanism in the biochemical reaction chamber to spread the feces to promote the biochemical reaction. However, it is difficult to find a power source in some places, the usage conditions are restricted, and using an external power source also violates the purpose of green environmental protection. Summary of the Invention

[0007] In view of this, the present invention provides a squatting device, aiming to solve the existing problems, and also provides an environmental protection toilet with such a squatting device.

[0008] To achieve the above object, the present invention provides a squatting toilet device, which includes a squatting toilet, a bracket, an opening / closing plate, a spreading plate, a transmission mechanism, a first elastic member, and a second elastic member. The squatting toilet is provided with a sewage outlet; the opening / closing plate is used to open and close the sewage outlet, and the spreading plate is located below the sewage outlet; the squatting toilet is arranged on the bracket and can move up and down relative to the bracket. The first elastic member positions the squatting toilet at a first height position in the natural state. When the squatting toilet is at the first height position, the second elastic member positions the opening / closing plate at a position blocking the sewage outlet, and positions the spreading plate at a first position; the power receiving end of the transmission mechanism is in transmission connection with the squatting toilet for receiving power from the squatting toilet, and the power output end of the transmission mechanism is connected to the spreading plate and the opening / closing plate. During the process of the squatting toilet moving from the first height position to the second height position, the squatting toilet, by means of the transmission mechanism, causes the opening / closing plate to move from the position blocking the sewage outlet to the position opening the sewage outlet, and causes the spreading plate to move from the first position to the second position and pass below the sewage outlet; the horizontal height of the first height position is higher than that of the second height position; the first position and the second position are respectively on both sides below the sewage outlet.

[0009] A squatting toilet device provided by the present invention is suitable for use in an environmental protection toilet. It arranges the squatting toilet to be able to move up and down, and is provided with an opening / closing plate, a spreading plate, and a transmission mechanism. When a user stands above the squatting toilet, the opening / closing plate and the spreading plate are linked.

[0010] In the natural state, that is, when no user stands above the squatting toilet, under the action of the first elastic member, the squatting toilet is at the first height position, and the second elastic member causes the opening / closing plate to block the sewage outlet. When a user enters the environmental protection toilet, even if they look towards the sewage outlet, they can only see the opening / closing plate and will not see the feces below the sewage outlet, effectively avoiding the situation that the user feels disgusted; at the same time, since the opening / closing plate blocks the sewage outlet when no user stands above the squatting toilet, the gas below the sewage outlet will not be uploaded to the environmental protection toilet during these periods, effectively reducing the unpleasant smell in the environmental protection toilet. When a user stands above the squatting toilet, the squatting toilet is pressed down, and the squatting toilet moves from the first height position to the second height position. The opening / closing plate is caused to open the sewage outlet through the transmission mechanism, and the feces discharged by the user fall from the opened sewage outlet, so that the opening / closing plate does not affect the normal use of the environmental protection toilet. When the user leaves the squatting toilet, under the action of the first elastic member, the squatting toilet returns to the first height position, and under the action of the second elastic member, the opening / closing plate re-blocks the sewage outlet.

[0011] In the natural state, the second elastic member positions the spreading plate at the first position. When the user stands on the squat toilet, the squat toilet is depressed. As the squat toilet moves downward, it drives the spreading plate to move through a transmission mechanism. The spreading plate moves under the sewage outlet to the second position, performing a fecal spreading action. After the user leaves the squat toilet, under the action of the first elastic member, the squat toilet returns to the first height position, and under the action of the second elastic member, the spreading plate returns to the first position, performing a second fecal spreading action. That is, every time a user uses the squat toilet once, the spreading plate will perform an action of moving from the first position to the second position and then back to the first position. The above actions are sufficient to complete the fecal spreading work, avoiding the accumulation of feces under the sewage outlet and enabling the feces to be fully decomposed.

[0012] Compared with the prior art, this kind of squat toilet device can reduce the unpleasant odor in the environmental protection toilet, and also makes users more willing to use the environmental protection toilet, improving the utilization rate of the environmental protection toilet and achieving the purpose of environmental protection. Moreover, it does not require an external power supply and only needs to utilize the gravity work of the user to complete the fecal spreading work, without being restricted by the power supply conditions.

[0013] Further, when the squat toilet moves downward, it drives the opening and closing plate to move horizontally and the spreading plate to move horizontally through the transmission mechanism.

[0014] Further, the transmission mechanism includes a transmission strip, a sliding arm, and a swing arm; the transmission strip is connected to the squat toilet and moves up and down with the squat toilet; the sliding arm can move horizontally relative to the bracket. A wedge drive structure is provided between the first end of the transmission strip and the sliding arm. When the transmission strip moves downward, it drives the sliding arm to move horizontally through the wedge drive mechanism. The second end of the sliding arm is hinged to the first end of the swing arm, the middle of the swing arm is hinged to the bracket, and the second end of the swing arm is used to connect the opening and closing plate and / or the spreading plate.

[0015] Further, the wedge drive structure includes a first inclined surface provided on the transmission strip and a second inclined surface provided on the sliding arm. The first inclined surface faces the sliding arm, and the second inclined surface faces the transmission strip; when the transmission strip moves downward, the first inclined surface abuts against the second inclined surface to make the sliding arm move horizontally.

[0016] Further, the squat toilet device includes two sets of the transmission mechanisms. The second end of the swing arm of one set of the transmission mechanisms is connected to the opening and closing plate, and the second end of the swing arm of the other set of the transmission mechanisms is connected to the spreading plate.

[0017] Further, a baffle is provided below the sewage outlet. The baffle is hinged to the bracket, and a third elastic member is provided between the baffle and the bracket. The third elastic member enables the baffle to be at the highest upward-flipped position in the natural state. The baffle can be flipped downward under the heavy pressure of a heavy object, and the baffle is located below the opening and closing plate.

[0018] Further, the middle of the spreading plate is arched to form a first inclined plate and a second inclined plate that are respectively inclined downward to both sides. A vertical first scraping plate is provided at the end of the first inclined plate, and a vertical second scraping plate is provided at the end of the second inclined plate.

[0019] Further, the lowest point of the first scraping plate is lower than the lowest point of the second scraping plate, and the bottom of the first scraping plate and / or the second scraping plate is serrated.

[0020] The present invention also provides an environmentally friendly toilet, which includes a housing and a biochemical reaction chamber provided in the housing, and further includes the above-mentioned squatting toilet device, and the squatting toilet device is erected above the biochemical reaction chamber.

[0021] The environmentally friendly toilet provided by the present invention, compared with the prior art, has less unpleasant gas in the housing, and can also make users more willing to use the environmentally friendly toilet. It does not require an external power supply, and only needs to utilize the gravity work of the user to complete the feces spreading work. This kind of environmentally friendly toilet has a good environmental protection effect.

[0022] Further, a seat plate that can be flipped from a vertical state to a horizontal state is provided in the housing. The seat plate is provided with support feet. When the seat plate is flipped to the horizontal state, the support feet of the seat plate press on the squatting toilet, and a through hole is provided in the middle of the seat plate.

[0041] Squatting toilet

[0042] The present invention provides a squatting toilet device, as Figures 1 to 5As shown in the figure, it includes a squatting toilet 1, a bracket 2, a folding plate 3, a spreading plate 4, a transmission mechanism 5, a first elastic member and a second elastic member. The squatting toilet 1 is provided with a sewage outlet 11; the folding plate 3 is used to open and close the sewage outlet 11, and the spreading plate 4 is located below the sewage outlet 11. The squatting toilet 1 is arranged on the bracket 2 and can move up and down relative to the bracket 2. The first elastic member makes the squatting toilet 1 located at a first height position in the natural state. When the squatting toilet 1 is at the first height position, the second elastic member makes the folding plate 3 located at the position of blocking the sewage outlet 11, and makes the spreading plate 4 located at a first position; the power receiving end of the transmission mechanism 5 is in transmission connection with the squatting toilet 1 for receiving power from the squatting toilet 1, and the power output end of the transmission mechanism 5 is connected to the spreading plate 4 and the folding plate 3. During the process of the squatting toilet 1 moving from the first height position to the second height position, the squatting toilet 1 makes the folding plate 3 move from the position of blocking the sewage outlet 11 to the position of opening the sewage outlet 11 by means of the transmission mechanism 5, and makes the spreading plate 4 move from the first position to the second position and pass under the sewage outlet 11.

[0043] Wherein, the horizontal height of the first height position is higher than that of the second height position.

[0044] Wherein, the first position and the second position are respectively located on both sides below the sewage outlet.

[0045] A squatting toilet device provided by the present invention is suitable for use in an environmental protection toilet. The squatting toilet 1 is arranged to be able to move up and down, and a folding plate 3, a spreading plate 4 and a transmission mechanism 5 are provided. When a user stands above the squatting toilet 1, the folding plate 3 and the spreading plate 4 are linked.

[0046] In the natural state, that is, when no user stands above the squatting toilet 1, under the action of the first elastic member, the squatting toilet 1 is located at the first height position, and the second elastic member makes the folding plate 3 block the sewage outlet 11. When a user enters the environmental protection toilet, even if he looks at the sewage outlet 11, he can only see the folding plate 3 and will not see the feces below the sewage outlet 11, effectively avoiding the situation that the user feels disgusted; at the same time, since the folding plate 3 blocks the sewage outlet 11 when no user stands above the squatting toilet 1, the gas below the sewage outlet 11 will not be uploaded to the environmental protection toilet during these time periods, effectively reducing the unpleasant gas in the environmental protection toilet. When a user stands above the squatting toilet 1, the squatting toilet 1 is pressed down, and the squatting toilet 1 moves from the first height position to the second height position. The folding plate 3 is made to open the sewage outlet 11 through the transmission mechanism 5, and the feces discharged by the user fall from the opened sewage outlet 11, so that the folding plate 3 will not affect the normal use of the environmental protection toilet. When the user leaves the squatting toilet 1, under the action of the first elastic member, the squatting toilet 1 returns to the first height position, and under the action of the second elastic member, the folding plate 3 blocks the sewage outlet 11 again.

[0047] In the natural state, the second elastic member positions the spreading plate 4 at the first position. When the user stands on the squat toilet 1, the squat toilet 1 is pressed downwards. The squat toilet 1 drives the spreading plate 4 to move through the transmission mechanism 5. The spreading plate 4 moves below the sewage outlet 11 to the second position. During the process of the spreading plate 4 moving from the first position to the second position, the first fecal spreading action is completed. After the user leaves the squat toilet 1, under the action of the first elastic member, the squat toilet 1 returns to the first height position, and under the action of the second elastic member, the spreading plate 4 returns to the first position. During the process of the spreading plate 4 returning from the second position to the first position, the second fecal spreading action is completed. That is, whenever a user uses the squat toilet 1 once, the spreading plate 4 will perform an action of moving from the first position to the second position and then back to the first position. The above actions are sufficient to complete the fecal spreading work, so as to avoid the accumulation of feces below the sewage outlet 11 and enable the feces to be fully decomposed.

[0048] Compared with the prior art, this kind of squat toilet device can reduce the unpleasant gas in the environmental protection toilet, and also enable users to be more willing to use the environmental protection toilet, improve the utilization rate of the environmental protection toilet, achieve the purpose of environmental protection, and does not require an external power supply. It only needs to utilize the gravity work of the user to complete the fecal spreading work, and is not restricted by the power supply conditions.

[0049] In the drawings, the first elastic member is preferably a spring 12 arranged between the bracket 2 and the squat toilet 1. However, the first elastic member can also be arranged between different components, as long as it can enable the first elastic member to position the squat toilet 1 at the first height position in the natural state. In addition to being arranged between the squat toilet 1 and the bracket 2, when the squat toilet 1 is fixedly connected to other accessories, the first elastic member can also be arranged between these accessories and the bracket 2, both of which can achieve the above purpose, and similar replacements also fall within the protection scope of the present invention.

[0050] In this embodiment, the squat toilet 1 drives the opening and closing plate 3 and the spreading plate 4 to perform horizontal movement through the transmission mechanism 5. The following Figure 2 and Figure 3 give the preferred embodiments of the present invention. Of course, in addition to adopting the Figure 2 and Figure 3 mechanical structure, there are other mechanical structures that can realize the horizontal movement of the opening and closing plate 3 and the spreading plate 4 when the squat toilet 1 moves downwards. As long as they can achieve the above functions and follow the innovative idea of the present invention, they should also fall within the protection scope of the present invention.

[0051] In this embodiment, as Figure 2 and Figure 3As shown in the figure, the transmission mechanism 5 includes a transmission bar 51, a sliding arm 52, and a swing arm 53; the transmission bar 51 moves up and down following the squatting pan 1; the sliding arm 52 can move horizontally relative to the bracket 2, and a wedge drive structure is provided between the first end of the transmission bar 51 and the sliding arm 52. When the transmission bar 51 moves downward, the sliding arm 52 is caused to move horizontally by means of the wedge drive structure. The second end of the sliding arm 52 is hinged to the first end of the swing arm 53, the middle of the swing arm 53 is hinged to the bracket 2, and the second end of the swing arm 53 is used to connect the opening and closing plate 3 and the spreading plate 4.

[0052] The wedge drive structure includes a first inclined surface provided on the transmission bar 51 and a second inclined surface provided on the sliding arm 52. The first inclined surface faces the sliding arm 52, and the second inclined surface faces the transmission bar 51; when the transmission bar 51 moves downward, the first inclined surface abuts against the second inclined surface to cause the sliding arm 52 to move horizontally.

[0053] Based on the structure as Figure 2 and Figure 3 shown, when the transmission bar 51 moves downward and abuts against the sliding arm 52, the sliding arm 52 moves away from the transmission bar 51 (i.e., to the right in the figure), and under the drive of the swing arm 53, the opening and closing plate 3 moves in the direction of opening the sewage outlet 11 (i.e., to the left in the figure), the opening and closing plate 3 opens the sewage outlet 11, and the spreading plate 4 moves from the first position to the second position. The so-called wedge drive structure specifically may be to provide an inclined surface on the transmission bar 51, or to provide an inclined surface on the sliding arm 52, or to provide inclined surfaces on both the transmission bar 51 and the sliding arm 52, as long as it can achieve the horizontal movement of the sliding arm 52 when the transmission bar 51 moves downward, and the above replacements all fall within the protection scope of the present invention. And similar mechanical mechanisms that can achieve the horizontal movement of the sliding arm 52 when the transmission bar 51 moves downward, as long as they can achieve the above functions and follow the innovative idea of the present invention, should also fall within the protection scope of the present invention.

[0054] Preferably, the squatting pan device includes two sets of transmission mechanisms 5, as Figure 3 shown, including two sets of transmission mechanisms 5, that is, as Figure 3 shown, the transmission bar 51, the sliding arm 52, and the swing arm 53 located above constitute the first set of transmission mechanisms, and the transmission bar 51, the sliding arm 52, and the swing arm 53 located below constitute the second set of transmission mechanisms. The two sets of transmission mechanisms are arranged one above the other. The first set of transmission mechanisms 5 is used to control the opening and closing plate 3, and the second set of transmission mechanisms 5 is used to control the spreading plate 4. By separating the two sets of transmission mechanisms 5 for transmission, it effectively avoids the situation where both the opening and closing plate 3 and the spreading plate 4 cannot work properly when a failure occurs in one of the links. Of course, it is also possible to only provide one set of transmission mechanisms 5, with the opening and closing plate 3 connected above the swing arm 53 of this set of transmission mechanisms 5 and the spreading plate 4 connected below the swing arm 53 of this set of transmission mechanisms 5, which is also possible. The above solutions all fall within the protection scope of the present invention.

[0055] In the drawings, the second elastic member is not shown because the second elastic member can be arranged between different components as long as it can make the opening and closing plate 3 located at the position of blocking the sewage outlet 11 and make the spreading plate 4 located at the first position in the natural state. For example, based on Figure 2 and Figure 3 the structure of the transmission mechanism 5 shown, the second elastic member can be arranged between the sliding arm 52 and the bracket 2, the second elastic member can also be arranged between the swing arm 53 and the bracket 2, the second elastic member can also be arranged between the opening and closing plate 3 and the bracket 2, and the second elastic member can also be arranged between the spreading plate 4 and the bracket 2, all of which can achieve the above purposes, and similar replacements also fall within the protection scope of the present invention.

[0056] In this embodiment, as Figure 4 shown, a baffle 6 is arranged below the sewage outlet 11. The baffle 6 is hinged to the bracket 2, and a third elastic member is arranged between the baffle 6 and the bracket 2. The third elastic member makes the baffle 6 located at the highest upward turning position in the natural state, and the baffle 6 can turn downward under the heavy pressure of a heavy object. When the user stands on the squatting pan 1, the opening and closing plate 3 opens the sewage outlet 11, and at this time, the user may still see the feces below the sewage outlet 11, and the gas below the sewage outlet 11 will also be transmitted upward through the sewage outlet 11, which will still affect the use experience to a certain extent. For this reason, in this embodiment, the baffle 6 is added. The baffle 6 is located at the highest upward turning position in the natural state. At this time, the baffle 6 blocks the sewage outlet 11. When the user discharges feces, the baffle 6 will turn downward under the heavy pressure of the feces, and the feces will fall downward. After the feces fall, the baffle 6 will return to the highest upward turning position again to solve the above problems. Further preferably, the baffle 6 is located below the opening and closing plate 3; when the baffle 6 fails to return to the highest upward turning position, if the baffle 6 is arranged below the opening and closing plate 33, the baffle 6 will not hinder the normal operation of the opening and closing plate 33.

[0057] In this embodiment, as Figure 5 shown, the middle of the spreading plate 4 is arched to form two first inclined plates 41 and second inclined plates 42 that are respectively inclined downward to both sides. A vertical first scraping plate 411 is arranged at the end of the first inclined plate 41, and a vertical second scraping plate 421 is arranged at the end of the second inclined plate 42. Based on the above structure, when feces fall above the spreading plate 4, or when feces are pushed above the spreading plate 4 during the movement of the spreading plate 4, since both sides of the spreading plate 4 are inclined, the feces will slide along the inclined first inclined plate 41 and second inclined plate 42 and will not stay on the spreading plate 4, which is beneficial to the full decomposition of feces. The first scraping plate 411 and the second scraping plate 421 are responsible for spreading the feces.

[0058] In this embodiment, the lowest point of the first scraper 411 is lower than the lowest point of the second scraper 421, and the bottom of the first scraper 411 and / or the second scraper 421 is set to be serrated. Thus, when the spreading plate 4 moves, for example, Figure 5 when the spreading plate 4 in Figure 5 moves from left to right, first the second scraper 421 with a higher lowest point spreads the upper-layer feces, and then the first scraper 411 with a lower lowest point spreads the lower-layer feces, so that the resistance during the movement of the spreading plate 4 is small. Preferably, the bottom of the first scraper 411 and / or the second scraper 421 is set to be serrated. That is, the bottom of the first scraper 411 can be set to be serrated, or the bottom of the second scraper 421 can be set to be serrated, or the bottoms of both the first scraper 411 and the second scraper 421 are set to be serrated. In this way, the surface of the feces is also scraped into a serrated shape, which can increase the contact area between the feces and the microorganisms and is beneficial to the decomposition of the feces.

[0059] Environmental protection toilet

[0060] The present invention also provides an environmental protection toilet, as Figure 6 shown, which includes a housing 71 and a biochemical reaction chamber provided in the housing 71, and further includes the above-mentioned squatting toilet device 72, and the squatting toilet device 72 is erected above the biochemical reaction chamber. The biochemical reaction chamber is located below the squatting toilet device 72 and is blocked by a step, so it is not shown. The feces discharged by the user fall into the biochemical reaction chamber and are decomposed.

[0061] In this embodiment, a seat plate 73 that can be turned from a vertical state to a horizontal state is provided in the housing 71 (when the seat plate 73 is turned up, the environmental protection toilet is a squatting toilet type environmental protection toilet). The seat plate 73 is provided with support feet 731. When the seat plate 73 is turned down to the horizontal state, the support feet 731 of the seat plate 73 press on the squatting pan 1, and a through hole 732 is provided in the middle of the seat plate 73. Thus, for children, or the elderly, or users who are not used to using squatting pans, they can turn down the seat plate 73. After the seat plate 73 is turned down, its support feet 731 press on the squatting pan 1. When the user sits on the seat plate 73, through the transmission of the support feet 731, the squatting pan 1 can also move downward to drive the above-mentioned opening and closing plate 3 and spreading plate 4 to move. Based on the above structure, the environmental protection toilet becomes a sitting toilet type environmental protection toilet.

[0062] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
