[0035] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] See also Figures 1 to 7 A multi-water cleaning nozzle includes an upper cover 500, a body 100 and a surface cover 200. The upper cover 500 is arranged on top of the surface cover 200. The body 100 and the surface cover 200 are surrounded by a receiving cavity. A first water flow core 300 is arranged in the receiving cavity. The first water flow core 300 has a first water flow cavity 310 and a second water flow cavity 320. The first water flow cavity 310 is formed by the middle channel of the first water flow core 300. The second water flow cavity 320 at least includes a water flow groove 321 arranged on the outer wall of the first water flow core 300.

[0037] The body 100 has a first injection cavity 110 connected to the accommodating cavity, and the first injection cavity 110 forms a first injection port 120 on the body 100. It also includes a water inlet channel, and the first water passage cavity 310 and the second water passage cavity 320 are both connected to the water inlet channel. The water in the water inlet channel flows through the first water passage cavity 310 and the first injection cavity 110 and then flows out from the first injection port 120 to form a first water pattern, such as Figure 4 After the water inlet channel passes through the second water chamber 320 and the first injection chamber 110, it flows out from the first injection port 120 to form a second water type, such as Figure 5 Two types of water spray can be realized through a water core and a spray port, thereby enriching the cleaning mode of the nozzle without adding an additional water core and spray port, and without increasing the volume of the nozzle.

[0038] In this embodiment, the water inlet channel includes a first water inlet channel 101 and a second water inlet channel 102; the water flow of the first water inlet channel 101 passes through the first water passage chamber 310 and the first injection chamber 110 and then flows out from the first injection port 120 to form a first water pattern; the water flow of the second water inlet channel passes through the second water passage chamber 320 and the first injection chamber 110 and then flows out from the first injection port 120 to form a second water pattern.

[0039] In this embodiment, a water supply channel and a switching mechanism (not shown) are also included, and the switching structure is used to switch the conduction between the water supply channel and the first water inlet channel 101 and the second water inlet channel 102. When the switching mechanism is in the first state, the water supply channel is connected to the first water inlet channel 101, and the water flow of the first water inlet channel 101 flows out from the first injection port 120 after passing through the first water passage chamber 310 and the first injection chamber 110, forming a first water pattern. When the switching mechanism is in the second state, the water supply channel is connected to the second water inlet channel 102, and the water flow of the second water inlet channel 102 flows out from the first injection port 120 after passing through the second water passage chamber 320 and the first injection chamber 110, forming a second water pattern. It can be understood that the switching mechanism is used to control the on-off and / or water inlet flow rate of the first water inlet channel 101 and the second water inlet channel 102. It should be further explained that, in this embodiment, the switching mechanism is a switching valve in the prior art or a solenoid valve / mechanical valve that controls the first water inlet channel 101 and the second water inlet channel 102 respectively, which will not be described in detail here.

[0040] Furthermore, the nozzle also includes a third water inlet channel 103 and a fourth water inlet channel 104. The main body 100 has a second injection chamber 130 connected to the accommodating chamber, and also includes a second water flow core 400 arranged in the accommodating chamber. The second water flow core 400 has a third water flow chamber and a fourth water flow chamber. The third water flow chamber is formed by the middle channel of the second water flow core, and the fourth water flow chamber at least includes a water flow groove arranged on the outer wall of the second water flow core; the third water flow chamber is connected to the third water inlet channel 103, and the fourth water flow chamber is connected to the fourth water inlet channel 104.

[0041] The water flow of the third water inlet channel 103 flows through the third water passage chamber 410 and the second injection chamber 130 and then flows out from the second injection port 140 to form a third water pattern. The water flow of the fourth water inlet channel 104 flows through the fourth water passage chamber 420 and the second injection chamber 130 and then flows out from the second injection port 140 to form a fourth water pattern. The third water pattern can be the same as the first water pattern, the second water pattern and the fourth water pattern. The parameters of the intermediate channels of the first water passage core and the second water passage core can also be set to be different, so that the first water pattern and the third water pattern are different. Similarly, the parameters of the water passage grooves of the first water passage core and the second water passage core can also be set to be different. The aperture ratio of the first injection chamber and the second injection chamber can also be set to be different, and the direction and flow rate of the water pattern can be changed in coordination with the water passage groove, so as to change the water pattern, so that the second water pattern and the fourth water pattern are different.

[0042] In this embodiment, the first water flow core 300 and the second water flow core 400 have the same structure. The structure of the nozzle of the present invention is explained below by taking the first water inlet channel 101 and the second water inlet channel 102, the first water flow core 300, and the first injection chamber 110 as examples.

[0043] The water channel 321 is tilted relative to the axis of the first water channel 300, so that the water flowing through the water channel 321 enters the first injection cavity 110 at an inclined angle, thereby forming a vortex in the first injection cavity 110, which is conducive to the water flow being scattered from the first injection port 120 to form a hollow scattered water. Figure 5 .

[0044] See also Figure 2 In this embodiment, more than two water channels 321 are provided, and the second water channel 320 further includes an annular groove 322 provided on the outer wall of the first water channel 300. Each water channel 321 is connected to the annular groove 322. After the water flow of the second water inlet channel enters the annular groove 322, it flows to the first injection chamber 110 through each water channel 321. Each water channel 321 is inclined in the same direction relative to the axis of the first water channel 300, so that it is easier to form a vortex in the first injection chamber 110.

[0045] Specifically, the first injection chamber 110 includes a rotating chamber 111, an accelerating chamber 112 and a scattering chamber 113 which are connected in sequence along the water flow direction. The inner diameter of the accelerating chamber 112 is smaller than that of the rotating chamber 111 and the scattering chamber 113, and is used to accelerate the vortex water flow in the rotating chamber. The water outlet end of the water channel 321 faces the side wall or bottom wall of the rotating chamber 111, and the bottom wall of the rotating chamber here refers to the bottom surface of the rotating chamber excluding the part connected to the accelerating chamber.

[0046] The rotating cavity 111, the accelerating cavity 112 and the scattering cavity 113 are arranged concentrically. The scattering cavity is U-shaped or horn-shaped, and / or the accelerating cavity is a cylindrical through hole.

[0047] The inner diameter of the first water passage chamber 310 decreases with the direction of the water flow, that is, the inner diameter of the first water passage chamber 310 decreases with the decrease of the distance from the first injection port 120, thereby accelerating the water flow passing through the first water passage chamber 310, so that the water flow can be ejected from the first water passage chamber 310 in a high flow rate and gathered state. It can be understood that the slope of the inner wall of the first water passage chamber 310 along the direction of the water flow can be consistent or inconsistent, that is, the first water passage chamber 310 can be composed of a plurality of chambers with different inclinations.

[0048] Furthermore, the first water passage chamber 310 is concentrically arranged with the first injection chamber 110, and the diameter of the end outlet of the first water passage chamber 310 is smaller than the inner diameters of the first injection chamber 110 and the first injection port 120, so that the high-speed water column flowing out of the first water passage chamber 310 can smoothly pass through the first injection chamber 110, and finally spray out columnar water from the first injection port 120, such as Figure 4 .

[0049] See also Figure 7 In this embodiment, the cover 200 is provided with a rectifying rib 210, which forms a rectifying cavity 220, and the rectifying cavity 220 connects the first water inlet channel 101 and the first water passage cavity 310, so that the water flow entering from the first water inlet channel 101 can be directed into the first water passage cavity 310. Similarly, the rectifying rib 210 also forms a rectifying cavity for connecting the third water inlet channel 103 and the third water passage cavity 410.

[0050] This embodiment also provides a toilet, including the aforementioned multi-water cleaning nozzle.

[0051] The cleaning nozzle of the utility model realizes the integration of multiple water outlets through the design of the internal flow channel and the water core, without adding an external switching valve or additional water outlets, which not only reduces the size of the nozzle, but also improves the overall aesthetics and convenience of use.

[0052] The above description shows and describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the utility model concept of this article through the above teachings or the technology or knowledge of the relevant field.
