Description

Technical Field

[0001] The present invention relates to the technical field of toilets, and in particular to a laying component, a toilet and a laying method. Background Art

[0002] A waterless toilet is an environmentally friendly sanitary device that does not require water flushing and does not rely on sewers. It is suitable for use in scenarios with limited conditions and lack of water sources, such as RVs.

[0003] Waterless toilets collect waste in a collection bag for subsequent batch processing. This requires placing the bag on the toilet seat before use. However, manual placement requires the user to bend over, which is not only tedious but may also be psychologically resistant to some users, hindering the widespread use of waterless toilets.

[0004] In some related technologies, a pair of material rolls are set in the internal space of the toilet seat. When the user presses a button, the waterless toilet automatically unwinds the rolls, and the unwound material strips are hot-melt welded and sealed to form a collection bag, thus overcoming the defects of manual bagging.

[0005] However, the material roll, the placement structure, and other internal structures of the toilet seat may interfere with each other. For example, an incineration-type waterless toilet converts excrement into ash and a small amount of gas through an incineration chamber at the bottom of the toilet seat. The incineration chamber generates a temperature of nearly 1,000 degrees Celsius during operation, and the heat transferred to the outside may damage the material roll. The incineration chamber also occupies the internal space of the toilet seat, limiting the space for the material roll and placement structure.

[0006] Therefore, the laying method in the related art has certain limitations in use and cannot be applied to some toilets. Summary of the Invention

[0007] In view of this, the present invention provides a laying assembly, a toilet and a laying method to solve the problem of limitations in the laying method.

[0058] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0059] It should be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the singular forms "a," "an," and "including" may also be intended to include the plural forms. The terms "comprising," "including," and "having" are inclusive and, therefore, specify the presence of the stated features, elements, and / or components, but do not preclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0060] Although the terms first, second, etc. may be used herein to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply a sequence or order when used herein. In addition, in the description of the present invention, unless otherwise clearly specified and limited, the terms "set" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0061] For ease of description, spatial relative terms can be used in the text to describe the relationship of an element or feature relative to another element or feature as shown in the figure, and these relative terms are, for example, "end", "length", "inside", "outside", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation except the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include the orientation on and below. The mechanism can be oriented in addition (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0062] There are many types of waterless toilets, such as packaged type, biodegradable type, incineration type, etc. Different waterless toilets require the use of a collection bag 11 to collect excrement for subsequent corresponding treatment, while ensuring the cleanliness of the waterless toilet itself.

[0063] In the related art, a pair of material rolls are disposed inside the toilet seat 1 of a waterless toilet. When the user presses a bagging button, the waterless toilet automatically unwinds the rolls and heat-welds the unwound material strips to seal the edges and form a collection bag 11. However, the rolls and related structures may interfere with other structures inside the toilet seat.

[0064] For example, incineration toilets generate high temperatures during incineration, which can easily damage the collection bag 11 stored in the toilet seat 1. Furthermore, the incineration chamber 5 and related structures occupy space within the toilet seat 1, limiting the placement of the material roll. Using high-temperature-resistant materials for the collection bag 11 not only increases implementation costs but also makes subsequent heat-sealing the bag 11 more difficult. Installing an insulating layer between the incineration chamber 5 and the collection bag 11 also increases costs and further occupies space within the toilet seat 1, hindering the miniaturization and portability of the incineration toilet.

[0065] Therefore, the laying method in the related art has certain limitations in use and cannot be applied to some toilets, which brings some obstacles to its promotion and application.

[0066] The following combination Figures 1 to 9 , describing embodiments of the present invention.

[0067] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 According to an embodiment of the present invention, on the one hand, a laying component 3 is provided, which includes a base 301 and a plurality of telescopic parts 303. The base 301 is used to be arranged on the side of the toilet cover 2 facing the toilet seat 1, and the plurality of telescopic parts 303 are arranged at intervals on the outer periphery of the base 301 in the circumferential direction. The telescopic parts 303 can be extended and retracted in the radial direction relative to the base 301 to support the outer edge of the material.

[0068] It is understood that the material can be a collection bag 11, especially a collection bag 11 with an elastic opening that can automatically close (for example, a collection bag 11 with an elastic band at the opening), and the outer edge of the material corresponds to the opening of the collection bag 11. The user first opens the toilet lid 2 and puts the outer edge of the contracted material on the telescopic member 303. Then, the user closes the toilet lid 2. The laying assembly 3 follows the toilet lid 2 to the toilet opening of the toilet seat 1. The telescopic member 303 extends radially outward, thereby expanding the outer edge of the material and laying the material on the toilet seat 1. Finally, the user reopens the toilet lid 2 to use the toilet.

[0069] On the one hand, the laying component 3 can realize the automatic expansion and laying of materials, thereby reducing the user's operating steps and making the use of the toilet more convenient; on the other hand, the laying component 3 is located on the toilet lid 2, and the user directly performs relevant operations on the opened toilet lid 2 (including setting the edge of the material on the telescopic part 303), thereby reducing the user's psychological rejection and being conducive to the promotion and application of the laying component. The laying component 3 can also be staggered with the structure in the toilet seat 1 to avoid mutual interference between structures, effectively improving the applicable scenarios of the laying component 3.

[0070] It should be noted that the number of telescopic parts 303 determines the shape of the material when it is stretched. Optionally, in some embodiments, the number of telescopic parts 303 is greater than or equal to 4, and they are evenly distributed in the circumferential direction, so as to stretch the bag opening more evenly.

[0071] In addition to the collection bag 11 mentioned above, the laying component 3 can also be used to lay other materials in the toilet.

[0072] For example, some public toilets require the use of disposable seat cushions. Conventional toilets typically require users to remove a disposable seat cushion from a cushion box, unfold it, and then bend over to place it on the toilet seat. This can be a psychologically irritating experience for users if the toilet seat is dirty. By using the placement assembly 3 of the present invention, users can first partially unfold the seat cushion, place it on the placement assembly 3, and then close the toilet lid 2. Finally, the placement assembly 3 can be used to place the seat cushion, thus overcoming the problems encountered in conventional toilets.

[0073] In order to stretch the material, in some embodiments, refer to Figure 3 and Figure 4 The laying component 3 also includes a first spring 304, a first winding spool 305 and a first pulling rope 306. The first spring 304 is arranged between the base 301 and the telescopic member 303, and is used to drive the telescopic member 303 away from the base 301. The base 301 includes an installation chamber, and the first winding spool 305 is arranged in the installation chamber. One end of the first pulling rope 306 is wound on the first winding spool 305, and the other end of the first pulling rope 306 is connected to the telescopic member 303. The first winding spool 305 is used to reel in or release the first pulling rope 306.

[0074] In the initial state, the first reel 305 reels the first pull cord 306, causing the telescopic member 303 to retract close to the base 301. Simultaneously, the first spring 304 is compressed by the telescopic member 303. After the toilet lid 2 is closed, the first reel 305 slowly unwinds the first pull cord 306. The first spring 304 gradually extends under its own elastic force, causing the telescopic member 303 to extend radially and spread the material. After the material is laid, the first reel 305 rewinds the first pull cord 306, causing the telescopic member 303 to retract and return to its initial state.

[0075] Using the first winding shaft 305 and the first spring 304 to drive the telescopic member 303 to retract and retract can simplify the driving structure, which is conducive to the miniaturization of the laying component 3, so that the laying component 3 can be adapted to toilets of more specifications, further improving the applicable scenarios of the laying component 3.

[0076] It is understandable that the laying component 3 can drive the first winding spool 305 in different ways.

[0077] For example, in some embodiments, referring to Figure 3 and Figure 4 The laying assembly 3 is electrically driven. Specifically, the laying assembly 3 further includes a first driver 302 for driving the first winding shaft 305. The first driver 302 can flexibly control the first winding shaft 305 to rotate forward or reverse, thereby electrically extending and retracting the laying assembly 3.

[0078] For example, in some other embodiments, the laying assembly 3 is driven mechanically. Figure 5 The laying component 3 also includes a first transmission mechanism, which transmits and connects the first winding shaft 305 and the rotating shaft of the toilet cover 2. The first transmission mechanism is used to drive the first winding shaft 305 to reel in the first pulling rope 306 when the toilet cover 2 is opened.

[0079] By driving through the first transmission mechanism, the retracting process and the opening process of the toilet lid 2 can be coupled together, and the telescopic member 303 is automatically retracted when the toilet lid 2 is opened, making the operation more convenient.

[0080] Further, in some embodiments, the first transmission mechanism includes a first gear set 307, a second winding shaft 308, a third winding shaft 309 and a second pull rope 310, the second winding shaft 308 is rotatably disposed on the toilet seat 1, the first gear set 307 is transmission-connected to the rotating shaft of the toilet cover 2 and the second winding shaft 308, the third winding shaft 309 is rotatably disposed on the base 301, the third winding shaft 309 is transmission-connected to the first winding shaft 305, and the second pull rope 310 is wound between the second winding shaft 308 and the third winding shaft 309.

[0081] It can be understood that the rotation range of the toilet lid 2 is generally not greater than 180°. By setting the first gear set 307, the second winding shaft 308 can reel in the second pull rope 310, thereby driving the third winding shaft 309 to rotate, and then driving the first winding shaft 305 to reel in the first pull rope 306. The first gear set 307 plays an amplifying role, thereby amplifying the rotation of the toilet lid 2 into multiple turns of the second winding shaft 308, thereby meeting the reeling demand of the first pull rope 306.

[0082] In some embodiments, the first transmission mechanism also includes a one-way clutch structure and a second spring. The one-way clutch structure is connected between the third winding spool 309 and the first winding spool 305. The second spring is connected between the third winding spool 309 and the base 301. The second spring is used to drive the third winding spool 309 to reel in the second pull rope 310.

[0083] During the process of opening the toilet lid 2, the second winding shaft 308 is wound and the third winding shaft 309 is unwound. The one-way clutch structure causes the first winding shaft 305 and the third winding shaft 309 to rotate synchronously to wind up the first pull rope 306. During the process of closing the toilet lid 2, the second winding shaft 308 is unwound and the third winding shaft 309 is wound. The one-way clutch structure causes the first winding shaft 305 and the third winding shaft 309 to be disconnected. The first winding shaft 305 remains in the wound state to facilitate the subsequent release of the first spring 304.

[0084] The one-way clutch structure can be purchased from a standard one-way clutch that meets the requirements, or the specific structure can be designed by the user based on the principle of the ratchet.

[0085] Exemplarily, the one-way clutch structure includes a second spring, a first ratchet and a second ratchet, the first winding shaft 305 and the third winding shaft 309 are coaxially arranged, the first ratchet is axially arranged at the end of the third winding shaft 309 facing the first winding shaft 305, and the second ratchet is axially arranged at the end of the first winding shaft 305 facing the third winding shaft 309, and the second spring presses the first winding shaft 305 toward the third winding shaft 309, so that the first ratchet and the second ratchet engage with each other.

[0086] During the closing process of the toilet lid 2, the third winding shaft 309 is wound, and at the same time, the first winding shaft 305 is driven to rotate synchronously through the one-way clutch structure to realize the winding of the first winding shaft 305. During the closing process of the toilet lid 2, the third winding shaft 309 rotates in the opposite direction, and the first ratchet overcomes the pressure of the second spring and pushes the first winding shaft 305 away from the third winding shaft 309, so that the first ratchet and the second ratchet disengage from each other, so that the first winding shaft 305 no longer rotates with the third winding shaft 309.

[0087] In some embodiments, the placement assembly 3 further includes a switch mechanism for locking or releasing the first winding spool 305. When the toilet lid 2 is closed, the one-way clutch structure disconnects the first winding spool 305 from the third winding spool 309, and the switch mechanism locks the first winding spool 305 to prevent the first spring 304 from rebounding. After the toilet lid 2 is fully closed, the switch mechanism releases the first winding spool 305, allowing it to rotate freely, and the first spring 304 rebounds to push out the telescopic member 303.

[0088] Exemplarily, the switch mechanism includes a button 311, a first connecting rod 312, and a third spring. The first connecting rod 312 is hinged to the toilet lid 2. The button 311 is disposed at one end of the first connecting rod 312 and extends through the toilet lid 2 to be exposed externally. The other end of the first connecting rod 312 is sleeved on the rotating shaft of the first winding shaft 305 and is axially movable between a first position and a second position. In the first position, the first connecting rod 312 and a third ratchet (located on the side of the rotating shaft of the first winding shaft 305) engage with each other, thereby unidirectionally locking the first winding shaft 305 and preventing the first spring 304 from rebounding. When the button 311 is pressed, the first connecting rod 312 moves to the second position. On the one hand, the first connecting rod 312 disengages the third ratchet, and on the other hand, the first connecting rod 312 pushes the first winding shaft 305 away from the third winding shaft 309, thereby releasing the first winding shaft 305 and allowing it to rotate freely. The first spring 304 rebounds and pushes the telescopic member 303 out.

[0089] Optionally, in some embodiments, the base 301 includes a plurality of limiting holes extending radially, and the plurality of limiting holes are circumferentially spaced apart and arranged on the periphery of the base 301 , and the first spring 304 is inserted into the limiting holes.

[0090] The number of the limiting holes matches the number of the telescopic parts 303. The limiting holes can play a positioning effect to prevent the first spring 304 from falling off the base 301. The setting of the limiting holes helps to extend the length of the first spring 304, so that it is suitable for using a first spring 304 with stronger stiffness and elasticity, ensuring that the first spring 304 can reliably push the telescopic part 303 to the target position.

[0091] Optionally, in some embodiments, the diameter of the telescopic member 303 is larger than the diameter of the limiting hole, and the shape of the telescopic member 303 close to the base 301 matches the shape of the peripheral surface of the base 301. In the initial state, the telescopic member 303 is covered on the base 301, thereby closing the limiting hole and preventing moisture in the external environment from invading the limiting hole, thereby protecting the first spring 304 and the first pulling rope 306 and extending the service life of the laying component 3.

[0092] Exemplarily, the base 301 is cylindrical in shape, and the telescopic member 303 has an arc-shaped surface on a side close to the base 301 .

[0093] Furthermore, in some embodiments, the limiting holes are arranged circumferentially around the first winding shaft 305 , the base 301 includes a wire hole connecting the installation chamber and the limiting holes, and the first pulling rope 306 passes through the wire hole to connect to the telescopic member 303 .

[0094] The first pulling rope 306 passes through the wire hole at the bottom of the limiting hole, passes through the first spring 304 and connects to the telescopic part 303, so that the layout of the first pulling rope 306 and the first spring 304 is more compact, which is conducive to the miniaturization of the laying component 3. In addition, the first spring 304 can also play a certain shielding and protective role to prevent the first pulling rope 306 from being accidentally damaged.

[0095] Optionally, in some embodiments, the laying component 3 further includes a retractable sleeve, one end of the sleeve is fixedly disposed in the limiting hole, the other end of the sleeve is connected to the retractable member 303, and the first pulling rope 306 passes through the sleeve to connect to the retractable member 303.

[0096] It is understandable that even with a certain amount of compression provided by the first pulling rope 306, the first spring 304, which has a relatively low stiffness, is still susceptible to bending and deformation when its total length is large, thereby failing to accurately push the telescopic member 303 to the target position. Furthermore, there is a risk that the telescopic member 303 will not be able to be extended and then compressed and retracted. While using a first spring 304 with a high stiffness can solve this problem, the implementation cost will also be increased accordingly.

[0097] By further adding a sleeve, the sleeve can further protect the first pulling rope 306. At the same time, the sleeve can also provide support to avoid bending and deformation of the first spring 304 during the extension and retraction process, ensuring that the laying component 3 can function reliably.

[0098] Optionally, in some embodiments, the outer diameter of the sleeve is smaller than the inner diameter of the first spring 304, and the first spring 304 is sleeved outside the sleeve. On the one hand, this design facilitates the use of a first spring 304 with a larger diameter, thereby increasing the stiffness of the first spring 304. On the other hand, the sleeve is composed of multiple sections of sub-tubes that are sequentially sleeved, which occupies a relatively large radial space. Placing the sleeve inside also leaves more space for sleeve installation.

[0099] Apart from Figures 1 to 5 In addition to the illustrated embodiment based on the first pulling rope 306 and the first spring 304 , the laying assembly 3 can also achieve the extension and retraction of the retractable member 303 through other methods.

[0100] For example, referring to Figure 6 and Figure 7 In some embodiments, the laying assembly 3 further includes a slider 313 and a connecting rod mechanism 314. The slider 313 is arranged on the base 301 and can move axially on the base 301. The connecting rod mechanism 314 is connected between the slider 313 and the telescopic member 303 and is used to convert the axial movement of the slider 313 into the radial movement of the telescopic member 303.

[0101] By adopting the rigid connecting rod mechanism 314 , after the position of the slider 313 is fixed, the position of the telescopic member 303 is also locked, so that the position of the telescopic member 303 in the extended state is more accurate.

[0102] Specifically, refer to Figure 7 The connecting rod mechanism 314 can adopt a design similar to the ribs of a folding umbrella. The slider 313 moves in the opposite direction toward the toilet cover 2 to extend the telescopic part 303. In addition to the radial movement during the extension process, the telescopic part 303 also moves in the axial direction away from the toilet cover 2, so as to press the material to the side of the toilet seat 1 to complete the laying of the material.

[0103] Similarly, the connecting rod mechanism 314 can be driven electrically or mechanically. In some embodiments, the laying assembly 3 also includes a second transmission mechanism, which is used to transmit the rotating shaft connecting the slider 313 and the toilet cover 2. The second transmission mechanism is used to drive the slider 313 to move when the toilet cover 2 is opened to retract the telescopic part 303.

[0104] By driving through the second transmission mechanism, the extension and retraction of the telescopic member 303 and the opening process of the toilet lid 2 can be coupled together, and the connecting rod mechanism 314 is driven mechanically to automatically retract the telescopic member 303 when the toilet lid 2 is opened, making the operation more convenient.

[0105] In some embodiments, the second transmission mechanism includes a third pull rope 315, a second gear set 316, and a fourth reel 317. The fourth reel 317 is rotatably mounted on the toilet seat 1. The second gear set 316 is drivingly connected to the rotating shaft of the toilet lid 2 and the fourth reel 317. One end of the third pull rope 315 is wound around the fourth reel 317, and the other end is connected to the slider 313. The fourth reel 317 can reel in the third pull rope 315, thereby pulling the slider 313 to move. The second gear set 316 acts as an amplification mechanism, thereby amplifying the rotation of the toilet lid 2 into multiple rotations of the fourth reel 317, thereby meeting the travel requirements of the slider 313.

[0106] In some embodiments, the third pulling rope 315 pulls the slider 313 to move toward the direction close to the toilet lid 2, thereby extending the telescopic member 303. The laying assembly 3 further includes a fourth spring 318, which is used to push the slider 313 to move away from the toilet lid 2, thereby retracting the telescopic member 303. The fourth spring 318 can be a tension spring (such as Figure 7 shown), compression spring, etc., the present invention is not limited to this.

[0107] In some embodiments, the laying assembly 3 further includes a switch mechanism, which is used to lock or release the slider 313. Specifically, the slider 313 may include a first snap-fit structure, and the switch mechanism is provided on the toilet lid 2, including a second snap-fit structure corresponding to the first snap-fit structure. When the slider 313 moves to a side close to the toilet lid 2, the first snap-fit structure and the second snap-fit structure snap-fit with each other, thereby locking the position of the slider 313. When the switch mechanism is pressed, the first snap-fit structure and the second snap-fit structure separate from each other, and the slider 313 moves away from the toilet lid 2 under the action of the fourth spring 318, thereby retracting the telescopic member 303.

[0108] For other possible implementations, please refer to the relevant existing technologies and will not be described in detail here.

[0109] In some embodiments, the material is a collection bag 11, and the end of the telescopic member 303 is provided with a wire groove for positioning the opening of the collection bag 11. The laying assembly 3 is used to prop open the opening of the collection bag 11 so that the collection bag 11 can be placed on the toilet seat 1. The opening of the collection bag 11 has an elastic elastic ring (such as a rubber band) that can be locked in the wire groove, thereby ensuring that the collection bag 11 is stably fixed to the laying assembly 3 and preventing the collection bag 11 from accidentally falling off during the bagging process.

[0110] In some embodiments, the base 301 is detachably mounted on the toilet lid 2. A maintenance hole connecting to the installation chamber is provided on the side of the base 301 facing the toilet lid 2. During normal use, the toilet lid 2 covers the maintenance hole, and the first driver 302 and other components are hidden within the installation chamber, protecting the life of the first driver 302 from external environmental influences. During maintenance, the base 301 can be removed to expose the installation chamber and its internal components, facilitating related operations.

[0111] Reference Figure 1 、 Figure 2 According to an embodiment of the present invention, in a second aspect, a toilet is provided, comprising a toilet seat 1, a toilet cover 2, a fixing assembly and a laying assembly 3 provided by the present invention. The toilet seat 1 has a cavity inside, and a toilet seat opening connected to the cavity is provided on the top of the toilet seat 1. The toilet cover 2 is rotatably provided on the top of the toilet seat 1 for covering the toilet seat opening. The laying assembly 3 is provided on the toilet cover 2 for holding open a collection bag 11. The fixing assembly is provided around the toilet seat opening for fixing the bag opening of the collection bag 11.

[0112] The toilet includes the laying component 3 provided by the present invention, and therefore has the corresponding beneficial effects brought about by the laying component 3, which will not be described in detail here.

[0113] In some embodiments, the fixing assembly includes a second driver 401 and a limiting member 402. The second driver 401 is used to drive the limiting member 402 to extend and retract in the vertical direction to limit or release the bag opening. The limiting member 402 can hook the bag opening to prevent the bag opening from rebounding, and cooperate with the telescopic member 303 to complete the laying. After the excretion is completed, the second driver 401 drives the limiting member 402 to retract, thereby releasing the bag opening, causing the bag opening to rebound and close, and realizing the automatic falling and recycling of the collection bag 11. With the rebound and contraction of the elastic ring, the collection bag 11 can automatically complete the closing of the bag opening after release, preventing the excrement in the collection bag 11 from overflowing, thereby eliminating the steps of manually closing and tying the collection bag 11, and further realizing the automation of the toilet.

[0114] Furthermore, in some embodiments, the fixing assembly is located within the cavity. It is understood that the toilet includes a toilet ring 6 rotatably disposed on the toilet seat 1 and located between the toilet lid 2 and the toilet seat 1. Placing the fixing assembly within the cavity can prevent the fixing assembly from occupying space on top of the toilet seat 1, thereby making the toilet compatible with existing toilet rings 6 and facilitating implementation of the toilet.

[0115] In order to further close the bag opening, in some embodiments, refer to Figure 8 and Figure 9 The toilet also includes a sealing component 10, which includes a mounting ring 1001, a closing card 1002 and a heater. The mounting ring 1001 is set at the toilet seat, and there are multiple closing cards 1002. The closing cards 1002 are rotatably set on the mounting ring 1001. The multiple closing cards 1002 are arranged at intervals along the circumference of the mounting ring 1001. The heater is used to heat the closing card 1002 to hot-melt seal the collection bag 11.

[0116] After the fixing component releases the bag opening, the sealing component 10 can further close the bag opening completely based on the rebound and contraction of the collection bag 11 itself, and heat the bag opening through a heater to achieve hot melt sealing, further reducing the risk of excrement overflowing from the collection bag 11.

[0117] Specifically, in some embodiments, both the sealing assembly 10 and the fixing assembly are located within the cavity, with the fixing assembly located on the side of the sealing assembly 10 near the toilet opening. When the laying assembly 3 opens the collection bag 11, the closing clips 1002 rotate outward and open. When the fixing assembly releases the bag opening, the closing clips 1002 simultaneously retract inward, clamping the bag opening and sealing it. After sealing, the closing clips 1002 open again, releasing the collection bag 11 and allowing it to fall.

[0118] Furthermore, in some embodiments, the toilet further includes a support assembly 7, which is disposed within the cavity and below the sealing assembly 10. The support assembly 7 can support the bottom of the collection bag 11, thereby reducing the tension exerted by the bag opening on the fixing assembly. Furthermore, the support assembly 7 can prevent the collection bag 11 from falling under the weight of the excrement when the fixing assembly releases the bag opening, thereby preventing the bag opening from separating from the sealing assembly 10.

[0119] In some embodiments, the toilet further includes an incineration chamber 5 for incinerating excreta. Optionally, in some embodiments, the incineration chamber 5 is located within the cavity and below the support assembly 7. The bottom of the support assembly 7 has an openable drop opening that aligns with the feed opening of the incineration chamber 5. After the sealing assembly 10 is closed, the drop opening opens, and the collection bag 11 falls into the incineration chamber 5 for incineration.

[0120] Optionally, in some embodiments, the incineration chamber 5 uses microwave incineration to incinerate the excreta, thereby enabling more thorough incineration and reducing harmful intermediate products and excreta residues.

[0121] Specifically, the toilet also includes a microwave generator 8 and a power supply 9, which are electrically connected. The microwave generator 8 converts electrical energy into microwaves, which are applied to the incineration chamber 5, thereby rapidly dehydrating the excreta within the incineration chamber 5 and heating it up for combustion. Furthermore, the toilet includes a shielded door located at the feed inlet, which is used to open and close the inlet. This door prevents microwaves from escaping the incineration chamber 5, improving safety.

[0122] In some embodiments, the incineration chamber 5 is also provided with an exhaust port and an air inlet, both of which are connected to the interior of the incineration chamber 5. The air inlet is used to supply fresh air to ensure that the excrement is burned in an oxygen-rich environment, and the exhaust port is used to discharge the combustion gas products.

[0123] In some embodiments, a deodorization component is further disposed downstream of the exhaust port to remove toxic and harmful gas components from the exhaust. For example, the deodorization component may decompose the gas components using a catalyst, or may adsorb the components into a filter element for subsequent processing.

[0124] In a third aspect, the present invention further provides a laying method, which uses the toilet provided by the present invention and comprises the following steps:

[0125] Step S110 : Open the toilet lid 2 and put the collection bag 11 on the laying component 3 .

[0126] Step S120: Cover the toilet lid 2, spread the collection bag 11 with the laying component 3, and fix the bag opening of the collection bag 11 with the fixing component.

[0127] The laying method provided by the present invention uses the toilet provided by the present invention, and therefore has the corresponding beneficial effects brought by the incineration toilet, which will not be repeated here.

[0128] Optionally, in some embodiments, the laying method further comprises the following steps:

[0129] Step S130: The fixing assembly releases the belt opening, and the fixing assembly cooperates with the sealing assembly 10 to retract the belt opening and seal it.

[0130] Step S140 : the supporting assembly 7 opens the drop opening to allow the collection bag 11 to fall into the incineration chamber 5 .

[0131] Step S150: The incineration chamber 5 performs microwave incineration on the excrement.

[0132] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention. Such modifications and variations are all within the scope defined by the appended claims.
