Description

Technical Field

[0001] The present application relates to the field of bathroom technology, and in particular to a mixing device and an intelligent toilet. Background Art

[0002] Smart toilets are generally equipped with a foam shield function, which can prevent the splashing of accumulated liquid in the toilet cavity, block odors, and prevent dirt from adhering to the inner wall of the toilet when using the toilet.

[0003] The existing foam generating device uses an electric pump to extract foaming liquid, water and air for mixing to produce fine foam, which is then discharged to the water surface in the toilet cavity through a delivery pipe to form a thick foam layer.

[0004] Since the liquid storage chamber for storing the foaming liquid and the mixing chamber for mixing and generating foam in the related art are independently arranged, when making foam, a liquid pump is required to pump the foaming liquid in the liquid storage chamber into the mixing chamber, resulting in a large movement space occupied by the foam generating device and high production costs. Utility Model Content

[0005] The present application provides a mixing device and a smart toilet to solve the problems of large occupied movement space and high production costs.

[0006] In the first aspect, the present application provides a mixing device, comprising a cylinder, a partition, a rod, a driving member and a sealing assembly. The partition is arranged in the inner cavity of the cylinder, and the partition divides the inner cavity of the cylinder into a liquid storage chamber and a mixing chamber, and the liquid storage chamber and the mixing chamber are arranged along the axial direction of the cylinder. The partition is provided with a recessed portion recessed toward the mixing chamber, and the recessed portion is provided with a through hole, and the through hole connects the liquid storage chamber and the mixing chamber. The rod is arranged in the cylinder along the axial direction of the cylinder, and a spiral blade is provided on the outer periphery of the first end of the rod, and at least part of the spiral blade is located in the recessed portion. The driving member is arranged on the cylinder, and the driving end of the driving member is connected to the second end of the rod, and the driving member drives the rod to rotate along its circumference. The sealing assembly is arranged in the mixing chamber, and the sealing assembly can move along the axial direction of the through hole to seal the through hole.

[0007] Beneficial Effects: By integrating the liquid storage chamber and mixing chamber into the same barrel and cleverly utilizing the spiral blades and drive element, this invention achieves the effect of transferring the foaming liquid from the liquid storage chamber to the mixing chamber, eliminating the need for an additional liquid pump, significantly saving movement space and reducing production costs. Furthermore, the use of the sealing member and elastic member in conjunction with the rod and spiral blades makes the foaming process more controllable, allowing the flow rate of the foaming liquid to be adjusted as needed.

[0008] In an optional embodiment, the blocking assembly includes a blocking member and an elastic member.

[0009] The blocking member is disposed within the mixing chamber and is slidable along the axial direction of the barrel between a first position and a second position. When the blocking member is in the first position, the blocking member blocks the through hole, and when the blocking member is in the second position, the blocking member is disengaged from the through hole. A first end of an elastic member abuts against the blocking member, and a second end abuts against the inner wall of the barrel. The elastic member has a tendency to drive the blocking member toward the through hole.

[0010] Beneficial effect: The rotation of the spiral blade compresses the foaming liquid inside the recessed portion until the sealing member is pushed open, allowing the foaming liquid to enter the mixing chamber. After the driving member is stopped, the pressurization of the foaming liquid in the recessed portion is stopped, and the elastic member drives the sealing member to reset, and the sealing member re-seals the through hole. The setting of the elastic member and the elastic member are used together with the rod body and the spiral blade, which can make the foaming process more controllable and the flow rate of the foaming liquid can be adjusted as needed.

[0011] In an optional embodiment, the partition includes a confluence portion and a connecting portion. The confluence portion is configured as an annular structure that gradually inclines toward the mixing chamber from its periphery to its center. The connecting portion is configured as a plate-like structure, the peripheral surface of the connecting portion being connected to the inner peripheral surface of the confluence portion, and the connecting portion is provided with the recessed portion.

[0012] Beneficial Effects: The partition design not only isolates the liquid storage chamber from the mixing chamber, but also, through the inclined structure of the confluence, facilitates the smooth flow of foaming liquid into the mixing chamber under the action of the spiral blades, thereby improving foaming efficiency. The connection portion ensures that the foaming liquid can enter the mixing chamber through the through hole, while the recessed portion provides sufficient space for the spiral blades to fully stir the foaming liquid.

[0013] In an optional embodiment, a guide cylinder is further included, which is arranged on the cavity wall of the mixing cavity away from the partition, the axial direction of the guide cylinder coincides with the axial direction of the cylinder body, the sealing member is sleeved on the outside of the guide cylinder, and the sealing member is slidably matched with the guide cylinder, and the elastic member is arranged in the guide cylinder.

[0014] Beneficial effect: The setting of the guide cylinder makes the sliding of the blocking piece more stable, and the elastic piece can act on the blocking piece more effectively, ensuring that the blocking piece can accurately block the through hole when needed, or can smoothly detach from the through hole when needed, thereby achieving precise control of the foaming process.

[0015] In an optional embodiment, the blocking member is configured as a cylindrical structure, the first end of the blocking member is sleeved on the outside of the guide tube, and the inner wall of the blocking member is slidably engaged with the outer wall of the guide tube, the second end of the blocking member is closed, and the outer wall of the second end of the blocking member decreases along the direction from the first end to the second end of the blocking member.

[0016] Beneficial Effects: The cylindrical structure and closed second end design of the plugging piece enable it to maintain a better seal during sliding, preventing foaming liquid leakage. At the same time, the tapered design of the outer wall allows the plugging piece to seal the through hole more accurately.

[0017] In an optional embodiment, a fixing frame is further included, wherein a limiting hole is provided on the fixing frame, the rod body passes through the limiting hole, and the rod body and the limiting hole are slidably engaged along the circumference of the rod body.

[0018] Beneficial effect: The setting of the fixing frame not only enhances the stability of the rod body, but also prevents it from deflecting or shaking during the rotation process.

[0019] In an optional embodiment, the driving member is arranged on the end face of the cylinder close to the liquid storage chamber, the driving end of the driving member passes through the end face of the cylinder and is connected to the first end of the coupling, and the second end of the coupling is connected to the rod body.

[0020] Beneficial effects: The location of the driving member enables it to more directly drive the rod body to rotate, while the use of the coupling makes the connection between the driving end and the rod body more stable and reliable, thereby improving the overall performance and stability of the mixing device.

[0021] In an optional embodiment, the cylinder body includes a first cylinder and a second cylinder, the first cylinder and the second cylinder are both provided with open ends, the open ends of the first cylinder and the second cylinder are arranged opposite to each other, and the axes of the first cylinder and the second cylinder coincide with each other, the partition is arranged between the first cylinder and the second cylinder, and the partition is respectively connected to the first cylinder and the second cylinder.

[0022] Advantages: The split design of the barrel makes it easier to manufacture and assemble, while the connection structure between the first and second barrels ensures a tight seal between the liquid storage chamber and the mixing chamber. This design not only improves the production efficiency of the mixing device but also facilitates its subsequent maintenance and repair.

[0023] In an optional embodiment, a liquid adding channel is provided on the end face of the cylinder close to the liquid storage chamber, and the liquid storage chamber is connected to the liquid adding channel. A water inlet channel and a liquid discharge channel are provided on the outer peripheral surface of the cylinder, and the water inlet channel and the liquid discharge channel are connected to the mixing chamber. The water inlet channel is provided close to the liquid storage chamber, and the liquid discharge channel is provided away from the liquid storage chamber.

[0024] Beneficial Effects: The provision of a liquid addition channel, a water inlet channel, and a liquid discharge channel allows the mixing device to more conveniently access an external water source and foaming liquid. The provision of a liquid discharge channel also facilitates the discharge of waste liquid generated during the foaming process. This design not only improves the ease of use of the mixing device but also makes it more practical for practical applications.

[0025] In a second aspect, the present application also provides a smart toilet comprising the above-mentioned mixing device.

[0026] Because the smart toilet includes a mixing device and has the same effect as the mixing device, it will not be described here. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0038] The following combination Figures 1 to 7 , describing the embodiments of the present application.

[0039] According to an embodiment of the present application, on the one hand, a mixing device is provided, comprising a cylinder 1, a partition 2, a rod 5, a driving member 7 and a sealing assembly. The partition 2 is arranged in the inner cavity of the cylinder 1, and the partition 2 divides the inner cavity of the cylinder 1 into a liquid storage chamber 15 and a mixing chamber 16, and the liquid storage chamber 15 and the mixing chamber 16 are completely separated. The liquid storage chamber 15 and the mixing chamber 16 are arranged along the axial direction of the cylinder 1. The partition 2 is provided with a recessed portion 3 that is recessed toward the mixing chamber 16, and the recessed portion 3 is provided with a through hole 4, which connects the liquid storage chamber 15 and the mixing chamber 16. The rod 5 is arranged in the cylinder 1 along the axial direction of the cylinder 1, and a spiral blade 6 is provided on the outer periphery of the first end of the rod 5, and at least part of the spiral blade 6 is located in the recessed portion 3. The driving member 7 is arranged on the cylinder 1, and the driving end of the driving member 7 is connected to the second end of the rod 5. The driving member 7 drives the rod 5 to rotate along its circumferential direction. The blocking group is disposed in the mixing chamber 16 , and the blocking assembly can move along the axial direction of the through hole 4 to block the through hole 4 .

[0040] It can be understood that the driving member 7 drives the rod body 5 to rotate, and the spiral blade 6 arranged on the rod body 5 rotates synchronously. At this time, the spiral blade 6 located outside the recessed portion 3 transports the foaming liquid in the liquid storage chamber 15 to the recessed portion 3, and the spiral blade 6 located inside the recessed portion 3 continuously pressurizes the foaming liquid to compress the foaming liquid until the sealing component is pushed open, so that the foaming liquid can enter the mixing chamber 16. After the driving member 7 is stopped, the pressurization of the foaming liquid in the recessed portion 3 is stopped, and the sealing member re-seals the through hole 4.

[0041] It should be noted that the recessed portion 3 can be set as a cylindrical structure, and the inner diameter of the recessed portion 3 is close to the outer diameter of the spiral blade 6 to avoid a gap between the edge of the spiral blade 6 and the inner wall of the recessed portion 3 to ensure the pressurization effect on the foaming liquid.

[0042] In this embodiment, the present application integrates the liquid storage chamber 15 and the mixing chamber 16 within the same barrel 1 and cleverly utilizes the cooperation of the spiral blade 6 and the drive member 7 to achieve the effect of transferring the foaming liquid from the liquid storage chamber 15 to the mixing chamber 16. This eliminates the need for an additional liquid pump, significantly saving movement space and reducing production costs. Furthermore, the provision of the blocking assembly in conjunction with the rod body 5 and the spiral blade 6 makes the foaming process more controllable, allowing the flow rate of the foaming liquid to be adjusted as needed.

[0043] In some embodiments, the blocking assembly includes a blocking member 8 and an elastic member 9 .

[0044] The blocking member 8 is disposed within the mixing chamber 16 and is slidable along the axial direction of the cylinder 1 between a first position and a second position. In the first position, the blocking member 8 blocks the through-hole 4. In the second position, the blocking member 8 is disengaged from the through-hole 4. The first end of the elastic member 9 abuts against the blocking member 8, and the second end abuts against the inner wall of the cylinder 1. The elastic member 9 has a tendency to drive the blocking member 8 toward the through-hole 4.

[0045] In this embodiment, the spiral blade 6 rotates to compress the foaming liquid inside the recessed portion 3 until the sealing member 8 is pushed open, allowing the foaming liquid to enter the mixing chamber 16. After the driving member 7 is stopped, the pressurization of the foaming liquid in the recessed portion 3 is stopped, and the elastic member 9 drives the sealing member 8 to reset, and the sealing member 8 re-seals the through hole 4. The setting of the sealing member 8 and the elastic member 9 is used together with the rod body 5 and the spiral blade 6, which can make the foaming process more controllable and the flow rate of the foaming liquid can be adjusted as needed.

[0046] In some embodiments, the partition 2 includes a confluence portion 201 and a communication portion 202. The confluence portion 201 is configured as an annular structure that gradually inclines toward the mixing chamber 16 from its periphery to its center. The communication portion 202 is configured as a planar plate-like structure, the circumference of which is connected to the inner circumference of the confluence portion 201. The communication portion 202 is provided with a recessed portion 3.

[0047] Optionally, the communicating portion 202 may be configured to have the same inclination angle as the confluence portion 201 .

[0048] In this embodiment, the design of the partition 2 not only isolates the liquid storage chamber 15 from the mixing chamber 16, but also, through the inclined structure of the confluence portion 201, facilitates the smooth flow of the foaming liquid into the mixing chamber 16 under the action of the spiral blades 6, thereby improving foaming efficiency. The provision of the connecting portion 202 ensures that the foaming liquid can enter the mixing chamber 16 through the through hole 4. At the same time, the recessed portion 3 provides sufficient space for the spiral blades 6 to fully stir the foaming liquid.

[0049] In some embodiments, a guide cylinder 10 is further included, which is arranged on the cavity wall of the mixing chamber 16 away from the partition 2. The axial direction of the guide cylinder 10 coincides with the axial direction of the cylinder body 1. The blocking member 8 is sleeved on the outside of the guide cylinder 10, and the blocking member 8 and the guide cylinder 10 are slidably matched. The elastic member 9 is arranged in the guide cylinder 10.

[0050] Optionally, both ends of the guide cylinder 10 are open, or the end of the guide cylinder 10 facing the partition 2 is open, so that the spring can be placed in the inner cavity of the guide cylinder 10.

[0051] In this embodiment, the provision of the guide cylinder 10 makes the sliding of the sealing member 8 more stable, and at the same time the elastic member 9 can act more effectively on the sealing member 8, ensuring that the sealing member 8 can accurately block the through hole 4 when needed, or can smoothly detach from the through hole 4 when needed, thereby achieving precise control of the foaming process.

[0052] In some embodiments, the blocking member 8 is configured as a cylindrical structure, the first end of the blocking member 8 is sleeved on the outside of the guide tube 10, and the inner wall of the blocking member 8 is slidably fitted with the outer wall of the guide tube 10, the second end of the blocking member 8 is closed, and the outer wall of the second end of the blocking member 8 decreases along the direction from the first end to the second end of the blocking member 8.

[0053] Optionally, the inner cavity cross-section of the blocking member 8 can be set to be one of a circular, quasi-circular, and polygonal structure, and the cross-sectional edge of the guide cylinder 10 is adapted to the inner cavity cross-section of the blocking member 8 .

[0054] In this embodiment, the cylindrical structure and closed second end of the sealing member 8 enable the sealing member 8 to maintain a better seal during sliding, preventing leakage of the foaming liquid. Furthermore, the tapered outer wall design allows the sealing member 8 to more accurately seal the through hole 4.

[0055] In some embodiments, the inner diameter of the through hole 4 increases gradually from the liquid storage chamber 15 to the mixing chamber 16 , and the through hole 4 is adapted to the shape of the second end of the blocking member 8 .

[0056] In this embodiment, the increasing design of the inner diameter of the through hole 4 enables the foaming liquid to pass through the through hole 4 more smoothly into the mixing chamber 16, and at the same time adapts to the shape of the second end of the sealing member 8, ensuring the sealing and stability of the sealing member 8 when sealing the through hole 4.

[0057] In some embodiments, a fixing frame 11 is further included. A limiting hole is provided on the fixing frame 11 . The rod 5 passes through the limiting hole. The rod 5 and the limiting hole are slidably matched along the circumference of the rod 5 .

[0058] Optionally, a plurality of fixing frames 11 may be provided, and the plurality of fixing frames 11 are arranged in the inner cavity of the cylinder 1 at intervals along the axial direction of the cylinder 1 .

[0059] Optionally, the fixing frame 11 may be configured as a long strip structure, the limiting hole may be provided in the middle of the fixing frame 11 , and both ends of the fixing member may be fixedly connected to the inner wall of the liquid storage cavity 15 .

[0060] In this embodiment, the provision of the fixing bracket 11 not only enhances the stability of the rod 5 but also prevents it from deflecting or shaking during the rotation process.

[0061] In some embodiments, the driving member 7 is arranged on the end face of the cylinder 1 close to the liquid storage chamber 15, the driving end of the driving member 7 passes through the end face of the cylinder 1 and is connected to the first end of the coupling, and the second end of the coupling is connected to the rod body 5.

[0062] In this embodiment, the location of the driving member 7 enables it to more directly drive the rod body 5 to rotate. At the same time, the use of the coupling makes the connection between the driving end and the rod body 5 more stable and reliable, thereby improving the overall performance and stability of the mixing device.

[0063] In some embodiments, the cylinder body 1 includes a first cylinder 101 and a second cylinder 102, both of which are provided with open ends, the open ends of the first cylinder 101 and the second cylinder 102 are arranged relative to each other, and the axes of the first cylinder 101 and the second cylinder 102 coincide, and the partition 2 is arranged between the first cylinder 101 and the second cylinder 102, and the partition 2 is respectively connected to the first cylinder 101 and the second cylinder 102.

[0064] Optionally, the open end of the first tube 101 and the open end of the second tube 102 may be respectively provided with an outward folding structure, or a flange structure, and connected by bolts so that the partition 2 is clamped and fixed by the two folding structures or flange structures.

[0065] Optionally, a sealing rubber pad may be provided between the open end of the first tube 101 and the open end of the second tube 102 and the partition 2 to ensure a sealing effect.

[0066] In this embodiment, the split design of the barrel 1 makes it easier to manufacture and assemble, and the connection structure between the first barrel 101 and the second barrel 102 also ensures the sealing between the liquid storage chamber 15 and the mixing chamber 16. This design not only improves the production efficiency of the mixing device, but also facilitates its subsequent maintenance and repair.

[0067] In some embodiments, a liquid adding channel 12 is provided on the end face of the cylinder 1 close to the liquid storage chamber 15, and the liquid storage chamber 15 is connected to the liquid adding channel 12. A water inlet channel 13 and a liquid discharge channel 14 are provided on the outer peripheral surface of the cylinder 1, and the water inlet channel 13 and the liquid discharge channel 14 are connected to the mixing chamber 16. The water inlet channel 13 is provided close to the liquid storage chamber 15, and the liquid discharge channel 14 is provided away from the liquid storage chamber 15.

[0068] Optionally, the discharge channel 14 may be connected to the nozzle 17 through a pipe, so that the foam in the mixing chamber 16 can be sprayed out through the nozzle 17 .

[0069] Optionally, the liquid adding channel 12 may be provided on the peripheral surface of the liquid storage chamber 15 so as to be away from the mixing chamber 16 .

[0070] In this embodiment, the provision of the liquid addition channel 12, the water inlet channel 13, and the liquid discharge channel 14 allows the mixing device to more conveniently access an external water source and foaming liquid. The provision of the liquid discharge channel 14 also facilitates the discharge of waste liquid generated during the foaming process.
