Description

Technical Field

[0001] The utility model relates to the technical field of sanitary products, in particular to a flushing structure of an intelligent toilet. Background Art

[0002] Smart toilets typically flush through multiple flush ports to clean the inner walls of the toilet base. These include an upper flush port at the top and a lower flush port at the bottom. These ports are typically equipped with upper and lower nozzles. Flushing water is delivered to the nozzles via pipes and sprayed out of their outlets to clean the inner walls of the smart toilet base.

[0003] Currently, while the top and bottom nozzles of smart toilets in the industry have some conflicting features regarding flushing performance, flushing behavior, and noise levels, achieving excellent performance, issues such as splashing, backflow, and loud noise still exist during the flushing process. Consequently, most manufacturers in the industry are forced to set performance targets based on national standards. However, with the continuous advancement of product capabilities, consumers are increasingly demanding smart toilets, and products that simply meet national standards are no longer well-received.

[0004] Specifically, existing upper nozzles primarily increase flow rate by reducing the diameter of the water outlet, thereby enhancing the impact. However, this increased flow rate causes the water in the brush ring to flow too quickly, causing it to splash when scrubbing the inner wall of the toilet bowl. Furthermore, the increased flow rate causes the water jetting from the upper nozzle (i.e., the outlet hole within the upper nozzle) to form a columnar stream, failing to form a "surface-like" scrubbing pattern on the inner wall of the toilet bowl, resulting in incomplete cleaning of certain areas. Utility Model Content

[0005] The purpose of this utility model is to propose a flushing structure for an intelligent toilet, which distributes the water volume of the upper nozzle and the lower nozzle by setting a three-way pipe to achieve an excellent siphon effect, thereby avoiding splashing during the flushing process while ensuring the washing effect, and further reducing the problem of flushing noise, so as to overcome the shortcomings of the existing technology.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0008] The flushing structure also includes a water tank, a water pump and a tee pipe connected in sequence by pipes, and the water tank, water pump and tee pipe are all located on the rear side of the base; the tee pipe includes a first outlet and a second outlet, the first outlet is connected to the water inlet end of the upper nozzle, and the second outlet is connected to the water inlet end of the lower nozzle, and the diameter of the first outlet is larger than the diameter of the second outlet.

[0009] Preferably, the ratio between the diameter of the first outlet and the diameter of the second outlet is (6-7):(3-4).

[0010] Preferably, the ratio between the diameter of the first outlet and the diameter of the second outlet is 6.5:3.5.

[0011] Preferably, the water outlet is circular in shape.

[0012] Preferably, the flow rate of the water pump is 95 L / min.

[0015] The technical solution provided by the utility model may have the following beneficial effects:

[0016] 1. A three-way pipe is added inside the toilet seat, and the three-way pipe has a first outlet and a second outlet with different diameters to realize the distribution of different water volumes between the upper nozzle and the lower nozzle, so that the larger upper flushing water volume can simulate the effect of pouring water into the toilet with a bucket, so as to form a siphon effect instantly, and the smaller lower flushing water volume is used to assist in "pushing" the waste to the inner cavity outlet, thereby achieving an excellent siphon effect; moreover, this solution realizes the distribution of upper flushing water volume and lower flushing water volume through the design of the above structure, which is also beneficial to avoid splashing water during the flushing process while ensuring the washing effect, and further reduces the problem of flushing noise, so as to overcome the shortcomings of the existing technology.

[0024] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0025] The present technical solution provides a flushing structure of an intelligent toilet, comprising a toilet seat 1, an upper nozzle 2 and a lower nozzle 3; the toilet seat 1 comprises an integrally formed base 11 and a toilet ring 12, and the toilet ring 12 is located at the top of the base 11, a rotary flushing water channel 13 is provided inside the toilet ring 12, a plurality of water outlets 1321 are provided at the bottom of the rotary flushing water channel 13 and are interconnected with the inner cavity of the toilet seat 1, and the water outlet directions of the plurality of water outlets 1321 are all located in the same clockwise direction; the upper nozzle 2 is mounted on the top of the toilet seat 1, and the water outlet end of the upper nozzle 2 is connected to the water inlet of the rotary flushing water channel 13; the lower nozzle 2 is mounted on the bottom of the inner cavity of the toilet seat 3, and the water outlet end of the lower nozzle 2 faces the rear side of the toilet seat 1;

[0026] The flushing structure also includes a water tank 4, a water pump 5 and a tee pipe 6 connected in sequence by pipes, and the water tank 4, the water pump 5 and the tee pipe 6 are all located on the rear side of the base 11; the tee pipe 6 includes a first outlet 61 and a second outlet 62, the first outlet 61 is connected to the water inlet end of the upper nozzle 3, and the second outlet 62 is connected to the water inlet end of the lower nozzle 2, and the diameter of the first outlet 61 is larger than the diameter of the second outlet 62.

[0027] Existing upper nozzles primarily increase flow rate by reducing the diameter of the water outlet, thereby enhancing the impact force. However, this increased flow rate causes the water in the brush ring to flow too quickly, causing it to splash when scrubbing the inner wall of the toilet bowl. Furthermore, the increased flow rate causes the water jetting from the upper nozzle (i.e., the outlet hole inside the upper nozzle) to form a columnar stream, which fails to form a "surface-like" scrubbing pattern on the inner wall of the toilet bowl, resulting in incomplete cleaning of certain areas.

[0028] Therefore, in order to solve the above technical problems, this technical solution proposes a flushing structure of an intelligent toilet, such as Figure 1-3As shown, the toilet seat 1 includes an upper nozzle 2, a lower nozzle 3, a water tank 4, a water pump 5, and a tee pipe 6. Specifically, the present solution specifically adds a tee pipe 6 inside the toilet seat 1, and the tee pipe 6 has a first outlet 61 and a second outlet 62 of different diameters to achieve different water volume distribution between the upper nozzle 2 and the lower nozzle 3. Thus, a larger upper flushing water volume can simulate the effect of pouring water from a bucket into the toilet to form a siphon effect instantly, and a smaller lower flushing water volume can assist in "pushing" waste to the inner cavity outlet, thereby achieving an excellent siphon effect. Furthermore, the present solution achieves the distribution of upper and lower flushing water volumes through the design of the above structure, which is also beneficial for avoiding splashing during the flushing process while ensuring a good washing effect, and further reduces the problem of flushing noise, thereby overcoming the shortcomings of the prior art.

[0029] Furthermore, the bottom of the rotary flushing water channel 13 of the present invention is provided with a plurality of water outlets 1321 which are interconnected with the inner cavity of the toilet seat 1, and the water outlet directions of the plurality of water outlets 1321 are all located in the same clockwise direction, that is, the water outlet directions of the plurality of water outlets 1321 are all located in the clockwise direction or the counterclockwise direction, so that when flushing, a vortex brush circle water flow rotating in the clockwise direction or the counterclockwise direction can be formed in the inner cavity of the toilet seat 1, such as Figure 4-5 As shown in the direction of the arrow, the fluid in the toilet seat 1 can have a certain potential energy, similar to the "tornado" effect, which is more conducive to the fluid rotating the waste in the toilet seat 1, thereby discharging the waste from the inner cavity.

[0030] To further illustrate, the ratio between the diameter of the first outlet 61 and the diameter of the second outlet 62 is (6-7):(3-4).

[0031] In one embodiment of the present technical solution, the ratio between the diameter of the first outlet 61 and the diameter of the second outlet 62 is optimized to obtain a better siphon effect.

[0032] To further illustrate, the ratio between the diameter of the first outlet 61 and the diameter of the second outlet 62 is 6.5:3.5.

[0033] To further explain, the shape of the water outlet 1321 is circular.

[0034] Under the premise of a certain water flow rate, the best shape of the aperture is circular, which is conducive to uniform distribution of the fluid and avoids turbulence.

[0035] To further illustrate, the flow rate of the water pump 5 is 95 L / min.

[0036] Specifically, the rotary flushing channel 13 includes a main water channel 131 and an outlet water channel 132, with multiple outlet water channels 132 provided, each protruding from the bottom of the main water channel 131 at intervals. The bottom surface of the outlet water channel 132 slopes downward in the direction of water discharge, and the outlet 1321 is formed at the end of the outlet water channel 132 in the direction of water discharge. This facilitates the generation and release of the potential energy of the upflushing water flow within the toilet seat 1.

[0037] Furthermore, at least two water outlet channels 132 are provided. This is more conducive to forming a brush ring water flow with a larger water distribution area in the inner cavity of the toilet seat 1, so that the brush ring water flow covers the entire inner cavity of the toilet seat 1.
