Description

Technical Field

[0001] This utility model relates to the technical field of toilet brush nozzle devices, and in particular to a brush nozzle device and a toilet. Background Technology

[0002] Currently, the most common foam shield function in smart toilets on the market uses a fixed-point foam dispensing method. In this method, the foam falls vertically onto the ceramic or water surface and gradually accumulates to a certain height. This foaming method has the following drawbacks:

[0003] (1) Long foaming time: In order to achieve a certain thickness of foam, it often takes more than 20 seconds to foam. Users cannot wait for a long time before using the toilet, so the foam shield cannot play its role.

[0004] (2) Small coverage area: The foam mainly covers the water surface in this foaming method, which can only play the role of foam shield to isolate odor and prevent splashing, and cannot cover the brush ring surface;

[0005] (3) Splashing occurs in the early stage of foaming: In the early stage of foaming, the water pressure of the self-aspirating foaming device is low and insufficient to generate negative pressure at the air intake hole. Water is easily sprayed out through the air intake hole, causing splashing. Utility Model Content

[0006] This utility model provides a brush ring nozzle device and a toilet, which aims to improve the problem of water splashing caused by water flowing through the air intake hole in the early stage of foaming.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A brush ring nozzle device is provided with a foaming channel, which includes a first channel, an acceleration channel, and a second channel connected sequentially along the foaming direction. The water-passing cross-sectional area of ​​the acceleration channel is smaller than that of the first and second channels. The second channel is connected to a liquid inlet channel. It also includes an air inlet chamber, which has an air inlet connected to the atmospheric environment and an air outlet connected to the foaming channel. The air inlet and the air outlet are connected to each other to form an air inlet channel. The air inlet chamber has a water-blocking chamber with its opening facing the air outlet.

[0009] Furthermore, the bubble outlet channel is provided with several liquid outlets, and each liquid outlet is connected to the liquid inlet channel.

[0010] Furthermore, each liquid outlet is arranged in a circular array around the axis of the bubble channel.

[0011] Furthermore, it includes an adapter and a nozzle assembly with a seal adapted to the adapter. The adapter has a first channel and an acceleration channel connected to the first channel. The nozzle assembly has a second channel, which is connected to the first channel through the acceleration channel to form a foaming channel. The adapter also has an air inlet chamber and a liquid inlet channel.

[0012] Furthermore, the adapter is provided with a mounting cavity, which has an air outlet connected to the second channel; it also includes a top cover that fits over the mounting cavity, the space enclosed by the top cover and the mounting cavity forming an air inlet cavity, and the top cover has an air inlet.

[0013] Furthermore, an annular baffle is provided on the upper cover facing the air outlet, and the space enclosed by the annular baffle forms a water-blocking cavity.

[0014] Furthermore, the top cover and nozzle body are detachably connected to the adapter.

[0015] Furthermore, a flow channel is provided between the nozzle and the adapter, the adapter has an outlet connected to the flow channel, and the inlet channel is connected to the flow channel.

[0016] Furthermore, the nozzle component is provided with a guide surface on the edge of one end of the adapter, and the adapter is provided with a plug cavity. The plug cavity is provided with a contact surface that abuts against the end face of the nozzle component and a wall surface that is sealed and adapted to the outer side of the nozzle component.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model proposes a brush ring nozzle device, including an air inlet chamber. The air inlet chamber has an air inlet hole connected to the atmospheric environment and an air outlet connected to the foaming channel. The air inlet hole and the air outlet are interconnected to form an air inlet channel. The air inlet chamber has a water-blocking chamber with its opening facing the air outlet. In the initial stage of foaming, the water pressure is low, and the water flows out through the air outlet hole and into the water-blocking chamber, preventing water from being ejected from the air inlet hole. Simultaneously, when the water pressure increases, sufficient negative pressure generated at the air outlet hole draws water from the water-blocking chamber into the foaming channel along with the air, preventing water residue in the water-blocking chamber. Furthermore, this brush ring nozzle device allows foam to cover the brush ring surface with the water flow.

[0020] 2. The present invention proposes a brush ring nozzle device, wherein the foaming channel is provided with several liquid outlets, and each liquid outlet is connected to the liquid inlet channel, thereby improving the liquid inlet efficiency of the foaming liquid. At the same time, the foaming liquid is dispersed at different positions in the foaming channel, so that the foaming liquid is evenly diffused and the foaming efficiency is improved.

[0021] 3. The present invention proposes a brush ring nozzle device, including an adapter and a nozzle component that is sealed and adapted to the adapter. The adapter and the nozzle component are detachably connected. The nozzle component is a common brush ring nozzle in the prior art. Users can connect the adapter to the nozzle component to convert it into a brush ring nozzle with self-aspirating air and self-aspirating liquid functions, thereby expanding its application range and meeting the diverse usage needs of users.

[0022] 4. The brush ring nozzle device proposed in this utility model automatically forms a flow channel in the space between the nozzle and the adapter when the nozzle is connected to the adapter, which simplifies the mold opening difficulty and reduces the production cost.

Detailed Implementation

[0036] Example 1

[0037] The following is combined Figures 1-10 This utility model will be described in detail.

[0038] A brush ring nozzle device is provided with a foaming channel, which includes a first channel 101, an acceleration channel 102, and a second channel 3011 connected sequentially along the foaming direction. The water-passing cross-sectional area of ​​the acceleration channel 102 is smaller than that of the first channel 101 and the second channel 3011. The second channel 3011 is connected to a liquid inlet channel 107. It also includes an air inlet chamber 104, which is provided with an air inlet 201 connected to the atmospheric environment and an air outlet 105 connected to the foaming channel. The air inlet 201 and the air outlet 105 are interconnected to form an air inlet channel. The air inlet chamber 104 is provided with a water-blocking chamber 202 with its opening facing the air outlet 105.

[0039] During use, due to the low water pressure in the initial foaming stage, negative pressure cannot be generated in the second channel 3011. The water flows out through the air outlet and enters the water-blocking cavity 202, preventing water from being ejected from the air inlet. When the water pressure increases, the water flow is accelerated through the acceleration channel 102, generating negative pressure in the second channel 3011. This creates sufficient negative pressure at the air outlet, drawing water from the water-blocking cavity 202 into the foaming channel along with the air, preventing water residue in the water-blocking cavity 202. Furthermore, this brush ring nozzle device allows foam to cover the brush ring surface with the water flow.

[0040] In this embodiment, the foaming channel is provided with a plurality of liquid outlets 106, and each liquid outlet 106 is connected to the liquid inlet channel 107, thereby improving the liquid inlet efficiency of the foaming liquid. At the same time, the foaming liquid is dispersed at different positions in the foaming channel, so that the foaming liquid is evenly diffused and the foaming efficiency is improved. Furthermore, the liquid outlets 106 are arranged in a circular array around the axis of the foaming channel to ensure foaming uniformity.

[0041] In this embodiment, the device includes an adapter 10 and a nozzle 30 that is sealed and adapted to the adapter 10. The adapter 10 is provided with a first channel 101 and an acceleration channel 102 connected to the first channel 101. The nozzle 30 is provided with a second channel 3011, which is connected to the first channel 101 through the acceleration channel 102 to form the foaming channel. The adapter 10 is also provided with an air inlet chamber 104 and a liquid inlet channel 107.

[0042] In this embodiment, the adapter 10 is provided with a mounting cavity 103, and the mounting cavity 103 is provided with an air outlet 105 communicating with the second channel 3011; it also includes an upper cover 20 that covers the mounting cavity 103, and the space enclosed by the upper cover 20 and the mounting cavity 103 constitutes an air inlet cavity 104. The upper cover 20 is provided with an air inlet 201, which communicates with the air inlet cavity 104. Under the action of negative pressure in the second channel 3011, outside air enters the second channel 3011 sequentially through the air inlet 201, the air inlet cavity 104, and the air outlet 105. Furthermore, the upper cover 20 is provided with an annular partition 203 facing the air outlet 105, and the space enclosed by the annular partition 203 constitutes a water-blocking cavity 202.

[0043] In this embodiment, the upper cover 20 and the nozzle body are detachably connected to the adapter 10, such as... Figure 2 As shown, the nozzle 30 is a common brush ring nozzle in the prior art. Users can connect the adapter 10 to the nozzle 30 to convert it into a brush ring nozzle with a self-foaming function. If the self-foaming function is not needed, simply installing the nozzle body is sufficient to achieve the brush ring water function, thereby expanding its applicability and meeting diverse user needs. Specifically, both the upper cover 20 and the nozzle 30 are snap-fitted to the adapter 10. The upper cover 20 has a first buckle 3051, and the adapter 10 has a protrusion 108 that matches the first buckle 3051. Figure 5 As shown; the adapter 10 is also provided with a second fastener 3052, and the nozzle component 30 is provided with a groove 3012 that matches the second fastener 3052, such as Figure 6 As shown.

[0044] In this embodiment, as Figure 3As shown, the nozzle assembly 30 includes a nozzle body 301, which has a groove 3012 for detachably connecting the adapter 10 to one end of the nozzle body 301. The internal flow channel of the nozzle body 301 forms a second channel 3011. A limiting flange 3013 extending radially outward is provided on the outer surface of the other end of the nozzle body 301. A locking nut 302 is threaded onto the middle of the nozzle body 301. Rotating the locking nut causes the limiting flange 3013 and the locking nut 302 to abut against both sides of the toilet mounting hole, thereby locking the nozzle body 301 to the toilet. A nozzle 303 is rotatably connected to the water outlet end of the nozzle body 301. Specifically, the nozzle 303 is ball-jointed to the nozzle body 301, and the user can adjust the water or foam direction by rotating the nozzle 303. The other end of the nozzle body 301 is also threadedly fitted with a pressure cap 304, which abuts against the nozzle 303 to prevent the nozzle 303 from detaching from the nozzle body 301, and the pressure cap 304 is provided with a window for the nozzle 303 to pass through.

[0045] In this embodiment, a flow channel 40 is provided between the nozzle component 30 and the adapter 10. The adapter 10 has a liquid outlet 106 communicating with the flow channel 40, and a liquid inlet channel 107 communicating with the flow channel 40. Further, the edge of the nozzle component 30 connected to one end of the adapter 10 has a guide surface 3014, that is, the edge of the nozzle body 301 connected to one end of the adapter 10 has a guide surface 3014. The adapter 10 has a insertion cavity 109, which has an abutment surface abutting against the end face of the nozzle component 30 and a wall surface sealing and adapting to the outer side of the nozzle component 30. The space enclosed by the guide surface 3014, the abutment surface, and the wall surface constitutes the flow channel 40. Figure 7 and Figure 8 As shown.
