Description

Technical Field

[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, a cleaning device, and a smart toilet seat and a smart toilet having the cleaning device.

[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, and the first water trough is provided with a first water outlet hole and a second water outlet hole which pass through the nozzle in sequence;

[0012] a nozzle cover, disposed on one side of the nozzle, wherein a surface of the nozzle cover and the first water tank are closed to form a first 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] Water flows into the first internal water channel from the first water inlet nozzle, flows to the cavity area through the first water outlet hole and the second water outlet hole, and is sprayed out from the first guide hole.

[0015] Preferably, the second water inlet nozzle is connected to a second water trough provided on one side of the nozzle, a third water outlet hole is provided on the second water trough and passes through the nozzle, and a surface on one side of the nozzle cover is closed with the second water trough to form a second internal water channel. The water flows from the second water inlet nozzle into the second internal water channel, flows to the cavity area through the third water outlet hole, and is ejected from the second guide hole.

[0016] Preferably, the first water trough and the second water trough are arranged on the same side of the spray head.

[0017] Preferably, two steps are provided on the side away from the first water trough and the second water trough, the plane corresponding to the first water outlet and the second water outlet is the first step surface, and the plane corresponding to the third water outlet is the second step surface.

[0018] Preferably, the first internal water channel and the second internal water channel are not connected to each other.

[0019] Preferably, a water retaining rib is provided on a side of the guide cover close to the nozzle, and a gap is formed between the water retaining rib and the first step surface, or the gap is provided on a side of the guide cover close to the cavity area.

[0020] Preferably, the depth of the second water outlet hole is greater than the depth of the first water outlet hole.

[0021] Preferably, the nozzle cover and the nozzle are connected by clamping or welding. When the nozzle cover and the nozzle are connected by clamping, the nozzle is provided with a plurality of clamping ribs for fixing the nozzle cover.

[0022] The present invention also provides a cleaning device, which comprises the above-mentioned nozzle assembly and a driving device for driving the nozzle assembly to move.

[0023] The present invention also provides an intelligent toilet seat, which has the above-mentioned cleaning device and also includes a seat ring and a seat cover.

[0024] The present invention also provides an intelligent toilet having the above-mentioned cleaning device, and further comprising a ceramic body and a seat ring and a seat cover mounted on the ceramic body.

[0025] The beneficial effect of the present invention is that the nozzle assembly of the present invention can spray a pulsed cleaning water column without the need for a water pump component. During use, when water is sprayed from the first water outlet, the water flow rate reaches its maximum at the outlet. Due to the high water flow rate, a low-pressure area is formed around the water column, resulting in an air pressure difference with atmospheric pressure. When water enters the cavity area, the atmospheric pressure presses air into the cleaning water, thereby mixing the water with air. The first guide hole makes the water-air mixed more evenly, thereby improving cleaning power and overall comfort. While water is flowing out of the first water outlet, a part of the water in the first internal water channel will be discharged synchronously by the second water outlet. Since the amount of water in the second water outlet is less, when the water flowing out of the second water outlet enters the position of the first water outlet, a part of the water that has stepped up will be taken away by the water sprayed from the first water outlet, causing the flow rate to increase instantly, further increasing the cleaning power, and then the flow rate returns to normal levels. Then, when the water enters the first water outlet again, the flow rate continues to increase, and it repeats this cycle, so that the cleaning water flow has a pulse feeling. At the same time, since the sprayed cleaning water contains air, it can increase the area of ​​the buttocks to be cleaned.

[0026] Furthermore, the use of 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 the utilization of the internal space of the entire machine, facilitating the miniaturization of the machine core, reducing overall energy consumption, eliminating auxiliary components, and lowering heater power. It also reduces water consumption for cleaning.

[0027] 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 5 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 inlets 4 are provided at one end of the nozzle 1, wherein the first water inlet 401 is connected to the first water tank 101 provided on one side of the nozzle 1, and the first water outlet 103 and the second water outlet 104 which pass through the nozzle 1 are provided in sequence on the first water tank 101.

[0044] The nozzle cover 3 is located on one side of the nozzle 1. One side of the nozzle cover 3 and the first water tank 101 are closed to form a first internal water channel 106. The diversion cover 2 is located on the side of the nozzle 1 facing away from the nozzle cover 3. A cavity 5 is formed between the nozzle 1 and the diversion cover 2. The diversion cover 2 is provided with at least two diversion holes as outlets for the water to be sprayed out.

[0045] When the nozzle assembly of this embodiment is in use, water flows from the first water inlet nozzle 401 into the first internal water channel 106, flows within the first internal water channel 106, flows through the first water outlet hole 103 and the second water outlet hole 104 to the cavity area 5, and is ejected from the first guide hole 201. The nozzle assembly of this embodiment is commonly used as a cleaning nozzle assembly in smart bathroom products. When using the corresponding cleaning function of this nozzle assembly, the user can feel the cleaning water jet ejected by the cleaning assembly has a pulsating feeling.

[0046] like Figure 6 As shown in the water outlet principle diagram, it is assumed that the water outlet is the first water outlet 103. When water is ejected from the first water outlet 103, the water flow velocity reaches the maximum at the outlet position. Due to the fast water flow velocity, a low-pressure area will be formed around the water column, and there will be an air pressure difference with the atmospheric pressure. When water enters the cavity area 5, under the action of atmospheric pressure, this area presses the air into the cleaning water, so that air is mixed in the water. The cleaning water mixed with air continues to flow into the first guide hole 201 of the guide cover 2 after gathering in the cavity area 5. The water and gas are mixed more evenly in the guide cover 201. At this time, the cleaning power of the cleaning water column ejected by the nozzle cover 201 is increased, and the overall comfort is also improved. Combined with Figure 4 In this embodiment, while water is flowing out of the first water outlet 103, the second water outlet 104 will also divide a portion of the water in the first internal water channel 106 to flow out simultaneously. Since the water volume of the second water outlet 104 is smaller, the water flowing out of the second water outlet 104 at the same time will be less than the water flowing out of the first water outlet 103. When the water flowing out of the second water outlet 104 overflows to the position of the first water outlet 103, a part of the overflowing water will be carried away by the water sprayed from the first water outlet 103, causing the flow rate of the water sprayed from the first guide hole 201 to increase instantly. Because the water output of the second water outlet 104 is less than the water output of the first water outlet 03, the water output flow of the first water outlet 103 will periodically return to a normal level. When the water flowing out of the second water outlet 104 overflows into the first water outlet 103 again, the flow rate continues to increase, and the cycle continues, so that the cleaning water sprayed from the first guide hole 201 has a pulse feeling. At the same time, since the sprayed cleaning water contains air, it can increase the area of the user's body part to be cleaned.

[0047] Furthermore, the second water inlet nozzle 402 is connected to the second water tank 102 provided on one side of the nozzle 1, and the second water tank 102 is provided with a third water outlet hole 105 that passes through the nozzle 1. The surface of one side of the nozzle cover 3 is closed with the second water tank 102 to form a second internal waterway 107. Water flows from the second water inlet nozzle 402 into the second internal waterway 107, flows through the third water outlet hole 105 to the cavity area 5, and is ejected from the second guide hole 202. According to the usage preferences of users of smart bathroom products, general body cleaning functions are divided into buttocks cleaning and women's cleaning. For example, in this embodiment, the water flow provided by the first guide hole 201 can be used for the buttocks cleaning function, and the water flow provided by the second guide hole 202 can be used for the women's cleaning function. Of course, in other embodiments, they can also be interchanged.

[0048] Furthermore, the two diversion holes have different inner diameters, with the second diversion hole 202 having a larger inner diameter than the first diversion hole 201. The water ejected from the first diversion hole 201 primarily provides water for posterior washing, while the second diversion hole 202 provides water for feminine washing. In this embodiment, the smaller first diversion hole 201 results in a more concentrated water jet, resulting in a more concentrated and pulsating water jet for posterior washing. The larger second diversion hole 202 results in a more dispersed water jet, resulting in a gentler water jet for feminine washing.

[0049] Furthermore, the first and second water troughs 101, 102 are located on the same side of the nozzle 1 and, when combined with the nozzle cover 3, form corresponding first and second water paths 106, 107. Water flowing from the first water path 106 is ejected from the first guide hole 201, while water from the second water path 107 is ejected from the second guide hole 202. This arrangement facilitates switching between the posterior and feminine wash functions and also facilitates the use of the nozzle assembly. For example, water from the first water path 106 flows into the first guide hole 201 and is ejected. The water ejected from this water path has a pulsed feel, corresponding to the user's posterior wash function. Water from the second water path 107 flows into the second guide hole 202 and is ejected. The water ejected from this water path is a normal flow, corresponding to the feminine wash function. Of course, in other embodiments, the first water path 106 can also be configured to eject water corresponding to the second guide hole 202, while the second water path 107 can be configured to eject water corresponding to the first guide hole 201.

[0050] Specifically, such as Figure 4As shown, two steps 7 are provided on the side facing away from the first water trough 101 and the second water trough 102. The plane corresponding to the first water outlet 103 and the second water outlet 104 is the first step surface 702, and the plane corresponding to the third water outlet 105 is the second step surface 701. The two-step arrangement allows water flowing out of the first water outlet 103 and the second water outlet 104 to be collected and sprayed out of the first guide hole 201, while water flowing out of the third water outlet 105 is collected and sprayed out of the second guide hole 202. This distinguishes the water flow from the first guide hole 201 and the second guide hole 202, effectively separating water for buttocks washing and water for women's washing. For example, when using the buttocks washing function, water flows out of the first guide hole 201, while when using the women's washing function, water flows out of the second guide hole 202.

[0051] Furthermore, in order to prevent the second internal waterway 107 from affecting the water flow of the first internal waterway 106, Figure 2 As shown, in one embodiment, the first internal water channel 106 and the second internal water channel 107 are not connected to each other. This can ensure the stability of the water outflow from the first guide hole 201, making the pulsed water outflow from the first guide hole 201 more stable.

[0052] like Figure 5 As shown, in another embodiment, a water retaining rib 203 is provided on the side of the guide cover 2 close to the nozzle 1, and a gap 6 is formed between the water retaining rib 203 and the first step surface 702, or the gap 6 is provided on the side of the guide cover 2 close to the cavity area 5. The setting of the water retaining rib 203 realizes the formation of a gap 6 between the water retaining rib 203 and the first step surface 702. The function of the gap 6 is to further enhance the pulse feeling. In addition, due to the Venturi principle, the water flowing out of the water outlet is mixed with air. After passing through the cavity area and flowing into the guide hole, the water column mixed with air can be concentratedly sprayed out due to the aperture setting of the guide hole. At this time, the cleaning area of the sprayed cleaning water column is increased, and the ideal cleaning effect can be achieved under the condition of small water flow. In addition, the setting of the gap 6 can prevent all the water flowing out of the second water outlet 104 from being carried away by the water flowing out of the first water outlet 103 and entering the first guide hole 201. A portion of the water flowing out of the second water outlet 104 flows out of the gap 6 at the front end of the cleaning device and into the ceramic inner cavity, pre-wetting the ceramic inner cavity and reducing the adhesion of dirt. The provision of the gap 6 prevents the water from completely filling the cavity area and thus preventing the pulse feeling. Pulsation only occurs when the water in the cavity is not full.

[0053] Refer again Figure 4As shown, in this embodiment, the depth of the second water outlet 104 is greater than that of the first water outlet 103. As a result, water flowing in the first waterway 106 is allocated a larger amount of water to flow out of the first water outlet 103, while the second water outlet 104, which has a longer flow path and a deeper hole, is allocated a smaller amount of water. This allows water to flow simultaneously from the first and second water outlets 103 and 104, but at different water volumes. This avoids a delay in the pulse sensation and enhances the pulse sensation of water ejected from the first guide hole 201.

[0054] like Figure 5 As shown, in one embodiment, the nozzle cover 3 is connected to the nozzle 1 by a snap-fit or welding method. When the nozzle cover 3 is connected to the nozzle 1 by a snap-fit method, the nozzle 1 is provided with a plurality of retaining ribs 8 for securing the nozzle cover 3. The retaining ribs 8 facilitate the retaining of the nozzle cover 3 to the nozzle 1, making it easier to disassemble and clean the nozzle cover 3.

[0055] It can be understood that the center line of the first guide hole 201 is arranged to coincide with the center line of the first water outlet 103 , which can improve the water spraying efficiency of the first guide hole 201 and make the pulse effect of the first guide hole 201 better.

[0056] Example 2

[0057] like Figure 7 As shown, the present invention also provides a cleaning device comprising the aforementioned nozzle assembly 11 and a drive device 10 that drives the nozzle assembly 11. In this embodiment, the drive device may be a motor. Utilizing the nozzle assembly 11 of the present invention can improve the pulse cleaning effect of the cleaning device, enhance cleaning comfort, eliminate the need for auxiliary air pumps or high-frequency pulse pumps, reduce product costs, and enhance the user experience.

[0058] Example 3

[0059] like Figure 8 As shown, the present invention also provides a smart toilet seat having the above-mentioned cleaning device 12, and also including a seat ring 13 and a seat cover 14. 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.

[0060] Example 4

[0061] like Figure 9As shown, the present invention also provides an intelligent toilet comprising the aforementioned cleaning device 12, a ceramic body 9, a seat ring 13, and a seat cover 14. The intelligent toilet of the present invention has a simple structure, improves internal space utilization, and facilitates miniaturization of the machine core. It also reduces overall energy consumption, auxiliary components, heater power, and water consumption for cleaning, while also pre-wetting the ceramic.
