[0001] The present invention relates to the technical field of smart bathrooms, and in particular to a nozzle assembly and a cleaning device thereof, a smart toilet seat and a smart toilet. Background Art

[0002] With the popularity and application of smart toilets, users have higher requirements for the flushing function of smart toilets. For example, they require the water jet to have a pulse feeling, so that users can get a better cleaning experience.

[0003] However, the cleaning devices currently on the market rely on external auxiliary devices (air pumps, high-frequency pulse pumps, etc.) to spray water jets with a pulsed feel. This method has the following disadvantages:

[0004] 1. It is necessary to add additional parts, which increases the production cost of toilet manufacturing.

[0005] 2. The newly added components take up a larger internal space of the toilet, which has a great impact on the layout of the entire machine and cannot be miniaturized.

[0006] 3. The newly added components may generate loud noise and vibration of the entire device, affecting the user experience.

[0007] 4. Due to the addition of new components, the stability of the system will be affected to a certain extent, and the maintenance rate of the entire machine may also increase. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a nozzle assembly and a cleaning device thereof, a smart toilet seat and a smart toilet.

[0009] To solve the above technical problems, the present invention adopts the following technical solutions:

[0010] A nozzle assembly comprising:

[0011] A nozzle, wherein one end of the nozzle is provided with at least two water inlet nozzles, wherein the first water inlet nozzle is connected to a first water trough provided on one side of the nozzle, the first water trough is provided with a first water outlet hole penetrating the nozzle, and the second water inlet nozzle is connected to a second water trough provided on the side of the nozzle;

[0012] a nozzle cover, disposed on one side of the nozzle, wherein one side surface of the nozzle cover is closed with the first water tank to form a first internal water channel, and one side surface of the nozzle cover is closed with the second water tank to form a second internal water channel;

[0013] The guide cover is provided on the side of the nozzle away from the nozzle cover, and at least two guide holes are provided on the guide cover. A cavity area is formed between the nozzle and the guide cover, wherein:

[0014] The nozzle is also provided with a flow channel communicating with the first water tank and the second water tank.

[0015] Preferably, a slope is provided on the side of the nozzle close to the guide cover, and the second water outlet is located on the slope, and the slope forms a water accumulation area on the side of the nozzle close to the guide cover.

[0016] Preferably, a tangential water inlet is provided between the second water inlet nozzle and the second water outlet hole, so that the water flow rotates in the second internal water channel.

[0017] Preferably, the aperture of the second water outlet hole is larger than the aperture of the first water outlet hole.

[0018] Preferably, the diameter of the second flow guide hole is larger than the diameter of the first flow guide hole.

[0019] Preferably, the center line of the first flow guide hole is arranged to coincide with the center line of the first water outlet hole, and the center line of the second flow guide hole is arranged to coincide with the center line of the second water outlet hole.

[0020] Preferably, a first water retaining rib is provided on the side of the guide cover close to the nozzle, a gap is formed between the first water retaining rib and the nozzle, or the gap is provided on the guide cover and close to the cavity area; a second water retaining rib and a third water retaining rib are provided on the side of the nozzle close to the guide cover and at the connection with the guide cover.

[0021] The present invention also provides a cleaning device having the nozzle assembly as described above, and further comprising a driving device for driving the nozzle assembly to move.

[0022] The present invention also provides an intelligent toilet seat, which has the cleaning device as described above and also includes a seat ring and a seat cover.

[0023] The present invention also provides an intelligent toilet having the cleaning device as described above, further comprising a ceramic body and a seat ring and a seat cover mounted on the ceramic body.

[0024] The beneficial effect of the present invention is that the nozzle assembly of the present invention can spray out a pulsed cleaning water column without the need for a water pump component. When the user is in use, when water is sprayed out from the first water outlet, a small portion of the water in the first internal water channel flows through the flow channel to the second internal water channel and flows out from the second water outlet. By designing the size of the flow channel, the water flowing out of the first water outlet will not be sprayed out, but will slowly overflow to the side of the nozzle, so that the water quickly fills the water accumulation area on the side of the nozzle. When the water reaches the first water outlet, part of the overflowing water will be taken away by the water sprayed from the first water outlet, so that the flow rate increases instantly, further increasing the cleaning power, and then the flow rate returns to normal level. Then, when the water overflows to the first water outlet again, the flow rate continues to increase, and it repeats back and forth, so that the cleaning water flow has a pulsed feeling. At the same time, when water is ejected from the first water outlet, the water flow velocity reaches its maximum at the outlet. Due to the high water flow velocity, according to the Venturi principle, a low-pressure area will be formed around the water column, and there will be an air pressure difference with the atmospheric pressure. When the water passes through the cavity area, the atmospheric pressure will press the air into the cleaning water in this area, so that the water is mixed with air. The cleaning water mixed with air is made more evenly mixed by the guide cover, thereby increasing the cleaning power and overall comfort.

[0025] This nozzle assembly eliminates the need for a conventional water pump, reducing the number of components in the cleaning device and lowering production and after-sales costs. Furthermore, the nozzle assembly of the present invention boasts a simple structure, further improving internal space utilization, facilitating miniaturization of the machine core, reducing overall energy consumption, eliminating auxiliary components, and lowering heater power. It also reduces water consumption for cleaning.

[0026] Other features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0040] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0041] Example 1

[0042] like Figures 1 to 6 As shown, in this embodiment, a nozzle assembly is provided, including: a nozzle 1, a nozzle cover 3, and a guide cover 2.

[0043] At least two water inlet nozzles 4 are provided at one end of the nozzle 1, wherein the first water inlet nozzle 401 is connected to the first water trough 112 opened on one side of the nozzle 1, and the first water outlet hole 101 is opened on the first water trough 112 and passes through the nozzle 1, wherein the second water inlet nozzle 402 is connected to the second water trough 110 opened on one side of the nozzle 1.

[0044] The nozzle cover 3 is provided on one side of the nozzle 1 , and one side surface of the nozzle cover 3 is closed with the first water tank 112 to form a first internal water channel 108 , and one side surface of the nozzle cover 3 is closed with the second water tank 110 to form a second internal water channel 109 .

[0045] The guide cover 2 is provided on the side of the nozzle 1 away from the nozzle cover 3, and a cavity area 5 is formed between the nozzle 1 and the guide cover 2. At least two guide holes are provided on the guide cover 2 as outlets for water to be sprayed out.

[0046] A connecting flow channel 107 is provided between the first water channel 112 and the second water channel 110 on the nozzle 1. Specifically, when the nozzle assembly of this embodiment is in use, for example, water flows from the first water inlet nozzle 401 into the first internal water channel 108. Most of the water flows from the first water outlet 101 to the cavity area 5, while a small portion of the water flows through the flow channel 107 into the second water channel 110 and flows from the second water outlet 102 to the cavity area 5. At this time, the water flow from the first water outlet 101 is stable, continuous, and high in volume. However, the water flowing out of the second water outlet 102 is smaller and may be discontinuous because it is only supplied through the smaller flow channel 107. When the water flow from the first water inlet nozzle 401 is collected in the cavity area 5 on the other side of the nozzle through the two water outlet holes and ejected from the first guide hole 201 accordingly, the water volume of the first water outlet hole 101 is concentrated, and the water volume of the second water outlet hole 102 is smaller as auxiliary water outlet, which makes the water column ejected from the first guide hole 201 have a pulse feeling. The nozzle assembly of this embodiment can be used as a cleaning nozzle assembly in smart bathroom products. When the user uses the cleaning function corresponding to the nozzle assembly, he can feel that the water column ejected by the cleaning assembly has a pulse feeling. Through the ingenious design of the nozzle assembly structure, the pulse feeling of the cleaning water can be achieved, which can save the original water pump device, directly reduce the components of the cleaning device, and effectively reduce the production and after-sales costs. In addition, the nozzle assembly of the present invention has a simple structure. The use of the nozzle assembly of the present invention can improve the utilization rate of the internal space of the entire intelligent toilet, which is conducive to the miniaturization of the machine core, reduces the energy consumption of the entire machine, reduces auxiliary components, and reduces the power of the heater.

[0047] In one embodiment, a slope 105 is provided on the side of the nozzle 1 close to the diversion cover 2, and the second water outlet 102 is located on the slope 105. The slope 105 forms a water accumulation area 104 on the side of the nozzle 1 close to the diversion cover 2. Since the installation position of the entire nozzle device in the smart toilet is not horizontal, but usually tilted, the slope 105 can enable water to quickly accumulate in the water accumulation area 104. Of course, in other embodiments, the side of the nozzle 1 close to the diversion cover 2 can be set to a flat surface, a U-shape, or an arc shape. The change in shape will affect the accumulation speed of water on the side of the nozzle 1 close to the diversion cover 2, but will not affect the final pulse water effect.

[0048] Furthermore, when water is ejected from the first water outlet 101, a small portion of water in the first internal water channel 108 flows through the flow channel 107 to the second internal water channel 109, and then flows out of the second water outlet 102. The smaller flow channel 107 restricts the water from the first water outlet 101 from being ejected directly, and merges with the water flowing out of the second water outlet 102. The obstruction of the slope 105 enables the water to quickly fill up the water accumulation area 104. Figure 2 When the water overflowing from the second water outlet 102 flows through the water accumulation area 104 to the first water outlet 101, part of the overflowing water will be carried away by the water sprayed from the first water outlet 101, causing the flow rate of the water column sprayed from the guide hole 201 to increase instantly. At this time, the cleaning power is further increased, and then the flow rate returns to normal level. When the water overflowing from the second water outlet 102 overflows to the first water outlet 101 again, the flow rate continues to increase, and the cycle repeats, so that the cleaning water flow sprayed from the guide hole 201 has a pulse feeling during its use. At the same time, when water is sprayed from the first water outlet 101, the water flow rate reaches the maximum at the outlet position. Due to the fast water flow rate, combined with Figure 5 According to the Venturi principle, a low-pressure area will be formed around the water column, and there will be an air pressure difference with the atmospheric pressure. When the water passes through the cavity area 5, under the action of atmospheric pressure, the air is pressed into the cleaning water in the cavity area 5, so that the water is mixed with air. The cleaning water mixed with air is under the action of the guide cover 2. Specifically, when the water flows through the guide hole, the water and air are mixed more evenly. The sprayed water has a pulse feeling while also increasing the cleaning power and overall comfort.

[0049] In one embodiment, a tangential water inlet 111 is provided in the second water tank 110 between the second water inlet nozzle 402 and the second water outlet 102 to cause the water flow to rotate in the second internal waterway 109. The second internal waterway 109 is fed with water through the tangential water inlet 111, which allows the water flow to rotate at high speed within the cavity, resulting in a spiral shape of the water sprayed out, making the water spray softer and improving the user experience.

[0050] In one embodiment, the diameter of the second water outlet 102 is larger than that of the first water outlet 101. Specifically, when the first water inlet nozzle 401 is opened alone to allow water in, the water can flow out of the first water outlet 101 in a more concentrated manner. A small amount of water will also flow out of the second water outlet 102 through the flow channel 107, but it will not be sprayed out as concentratedly as the first water outlet 101. When the second water inlet nozzle 402 is opened alone to allow water in, the larger diameter of the second water outlet 102 can accommodate the majority of the water flow being sprayed out of this hole. Only a very small amount of water will overflow into the first internal waterway 112 through the flow channel 107. The water flowing out of the first water outlet 101 will not affect the water flow sprayed from the second water outlet 102 to the second guide hole 202. Of course, in other embodiments, the diameter of the first water outlet 101 can be set to be the same size as or larger than the diameter of the second water outlet to meet the needs of more cleaning methods.

[0051] In one embodiment, the aperture of the second guide hole 202 is larger than the aperture of the first guide hole 201. Specifically, the cleaning water column sprayed out by the first guide hole 201 can be more concentrated. For example, when the first guide hole 201 sprays a water column corresponding to the buttocks washing function, the smaller aperture can make the sprayed water column more concentrated and powerful, which can meet the user's experience requirements when using the buttocks washing function. When the second guide hole 20 sprays a water column corresponding to the women's washing function, the larger aperture can make the sprayed water column relatively gentle and slow, which makes the experience of female users more comfortable when using the women's function. Such a setting can meet the needs of more cleaning methods.

[0052] In one embodiment, the centerline of the first guide hole 201 is aligned with the centerline of the first water outlet 101, and the centerline of the second guide hole 202 is aligned with the centerline of the second water outlet 102. This arrangement ensures that the water jetted from the first water outlet 101 is concentrated through the first guide hole 201, and the water jetted from the second water outlet 102 is concentrated through the second guide hole 202. This does not affect the stability of water jets such as pulsed water jets and rotating water jets.

[0053] In one embodiment, a first water retaining rib 203 is provided on the side of the guide cover 2 close to the nozzle 1, and a second water retaining rib 103 and a third water retaining rib 106 are provided on the side of the nozzle 1 close to the guide cover 2 and at the connection with the guide cover 2. The structural setting of the water retaining rib can reduce water leakage and increase the accumulation speed of water flow on the side of the nozzle close to the guide cover. A gap 6 is formed between the first water retaining rib 203 and the nozzle 1, or the gap 6 is provided on the guide cover 2 and close to the cavity area 5. The setting of the gap 6 can increase the contact area between water and air, and according to the Venturi principle, it can increase the pulse feeling and cleaning of strong cleaning to a certain extent. In addition, the presence of the gap 6 means that the water flowing out of the first water outlet 101 or the second water outlet 102 will not be completely taken away and sprayed out from the guide hole. A part of it will flow out from the gap 6 at the front end of the cleaning device and enter the ceramic inner pit, which has the effect of pre-wetting the ceramic inner pit and reducing the sticking of dirt.

[0054] Example 2

[0055] like Figure 8 As shown, the present invention also provides a cleaning device having the above-mentioned nozzle assembly 9 and a drive device 8 that drives the nozzle assembly 9. In this embodiment, the drive device can be a motor. The cleaning device having the nozzle assembly of the present invention can achieve better pulse cleaning effect and more comfortable cleaning, eliminating the need for auxiliary air pumps or high-frequency pulse pumps, thereby reducing product costs and improving user experience.

[0056] Example 3

[0057] like Figure 9 As shown, the present invention also provides a smart toilet seat having the above-mentioned cleaning device 10, and also including a seat ring 11 and a seat cover 12. The smart toilet seat with the cleaning device of the present invention eliminates the need for an auxiliary air pump or high-frequency pulse pump, making the toilet seat more compact, smaller, and more beautiful.

[0058] Example 4

[0059] like Figure 10 As shown, the present invention also provides a smart toilet comprising the aforementioned cleaning device 10, a ceramic body 7, and a seat ring 11 and seat cover 12 mounted thereon. The smart toilet comprising the cleaning device 10 of the present invention has a simple structure, improves internal space utilization, and facilitates miniaturization of the toilet mechanism. It also reduces overall energy consumption, auxiliary components, heater power, and water consumption for cleaning, while also pre-wetting the ceramic.
