[0022] The present utility model will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included within the protection scope of the present utility model.

[0023] It should be understood that the spatially relative position terms used herein, such as "upper", "lower", "outer", "inner", etc., are for the purpose of facilitating description to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The spatially relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the figures.

[0024] The device can be oriented in other ways (rotated 90 degrees or other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly. In the present utility model, for convenience of description, when the toilet is in normal use, the direction facing the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is the horizontal direction, and the direction perpendicular to the ground is the vertical direction; the side close to the user is the front side, and the side away from the user is the rear side.

[0025] Referring to Figures 1 to 5 As shown, a toilet provided by a preferred embodiment of the present utility model can be used in cooperation with a water storage tank or directly connected to an external water source. The installation method of the toilet can be wall-mounted or floor-mounted, and the specific water inlet and sewage discharge methods are the same as those of a conventional toilet.

[0026] With reference to Figure 1 and Figure 2 As shown, specifically, a toilet includes a toilet main body 10 and a flushing nozzle 20 that cooperates with the toilet main body 10. In this embodiment, the material of the toilet main body 10 is selected to be made of ceramic material, which is easy to clean and has good stain resistance. The flushing nozzle 20 is used to form a flushing water flow to perform a flushing operation on the toilet main body 10. Moreover, the flushing nozzle 20 and the toilet main body 10 are designed in a split manner, which is convenient for the manufacture of the toilet main body 10 and also convenient for the later maintenance and replacement of the flushing nozzle 20.

[0027] Specifically, the toilet main body 10 includes a toilet inner wall 102 forming a toilet bowl cavity 101 and a seat ring platform 103 connected to the upper edge of the toilet inner wall 102. In this embodiment, the toilet inner wall 102 encloses to form the toilet bowl cavity 101. The seat ring platform 103 is used to support the seat ring of the toilet (not shown in the figure), so as to bear the pressure exerted by the user on the seat ring.

[0028] With reference to Figure 3 As shown, specifically, the flushing nozzle 20 includes a flushing cavity 201 and at least three flushing ports communicating with the flushing cavity 201. In this embodiment, after the external water flow enters the flushing cavity 201, it is discharged through at least three flushing ports to form at least three flushing water flows, and the three flushing water flows are respectively directed in different directions to ensure that the cleaning of the toilet bowl cavity 101 meets the requirements.

[0029] Furthermore, the toilet main body 10 further includes a guiding wall 104 connected to the seat ring platform 103 and protruding into the toilet bowl cavity 101. In this embodiment, the guiding wall 104 is located at the rear side of the top of the toilet bowl cavity 101 and in front of the flushing nozzle 20, so as to block the flushing nozzle 20, making it impossible for the user to observe the flushing nozzle 20 from the outside of the toilet.

[0030] Furthermore, the flushing nozzle 20 further includes a drain port 202 communicating with the flushing cavity 101, and the drain port 202 is disposed opposite to the guiding wall 104. In this embodiment, the drain port 202 and the guiding wall 104 are disposed opposite to each other along the front-rear direction, and the guiding wall 104 is located in front of the drain port 202. The guiding wall 104 has an arc-shaped structure, so that it can better guide the water flow discharged from the drain port 202.

[0031] Thus, after the external water flow enters the flushing cavity 201, a part of the water flow will be discharged from the drain port 202. Since the drain port 202 is disposed opposite to the guiding wall 104, the water flow discharged from the drain port 202 is directly discharged towards the guiding wall 104. After being guided by the guiding wall 104, it flows downward along the guiding wall 104 and forms a water curtain-like flushing water flow, increasing the flushing area of the flushing nozzle 20 for the toilet inner wall 102 and meeting the cleaning requirements of the toilet.

[0032] Furthermore, the drain port 202 is exposed in the toilet bowl cavity 101. In this embodiment, the water flow discharged from the drain port 202 directly flows into the toilet bowl cavity 101, so that the water flow directly contacts the guiding wall 104 located in the toilet bowl cavity 101, shortening the distance between the drain port 202 and the guiding wall 104. Avoiding the situation of water flow loss when the distance between the drain port 202 and the guiding wall 104 is relatively far, ensuring that the water flow discharged from the drain port 202 fully contacts the guiding wall 104, thereby forming a water curtain-like flushing water flow.

[0033] In an embodiment not shown, the drain opening 202 may also be exposed within the installation channel 105, that is, the water flow discharged from the drain opening 202 first passes through the installation channel 105 and then flows into the toilet bowl cavity 101.

[0034] With reference to Figure 4 and Figure 5 shown, specifically, the flushing nozzle 20 further includes a water inlet 203 communicating with the flushing cavity 201, and the drain opening 202 is exposed within the flushing cavity 201. In this embodiment, the drain opening 202 is directly communicated with the flushing cavity 201, that is, no additional communication channel is provided between the flushing cavity 201 and the drain opening 202, so that the water pressure flowing from the flushing cavity 201 to the drain opening 202 remains unchanged. At the same time, the structure of the drain opening 202 is simplified, that is, only an opening needs to be provided on the corresponding outer wall (installation wall 205) of the flushing nozzle 20. Similarly, the water inlet 203 is exposed within the flushing cavity 201.

[0035] Further, the axis of the drain opening 202 and the axis of the water inlet 203 are parallel to each other or collinear with each other. In this embodiment, preferably, the axis of the drain opening 202 and the axis of the water inlet 203 are collinear with each other, so that the water flow direction flowing out of the drain opening 202 from the flushing cavity 201 is the same as the water flow direction flowing into the flushing cavity 201 from the water inlet 203, that is, both water flow directions are along Figure 4 the axis direction Z in. Thus, after the water flow supplied by the external water source or the water tank flows into the flushing cavity 201 through the water inlet 203, it directly flows out of the drain opening 202 along the flushing cavity 201 without fluid turning, improving the water pressure flowing out of the drain opening 202 and ensuring a stable formation of a water curtain-like flushing water flow.

[0036] Specifically, the toilet main body 10 further includes an installation channel 105 communicating with the toilet bowl cavity 101. In this embodiment, the installation channel 105 provides an installation space for the flushing nozzle 20, and the flushing nozzle 20 is limited within the installation channel 105, thereby realizing the detachable connection between the flushing nozzle 20 and the toilet main body 10.

[0037] Specifically, the flushing nozzle 20 further includes a cleaning port 204 communicating with the flushing cavity 201, and the cleaning port 204 is exposed within the installation channel 105. In this embodiment, after the external water flow enters the flushing cavity 201, a part of the water flow will be discharged from the cleaning port 204, and the cleaning port 204 is exposed within the installation channel 105, which will cause the water flow discharged from the cleaning port 204 to directly flow into the installation channel 105, and the water flow in the installation channel 105 will eventually flow into the toilet bowl cavity 101. Thus, the installation channel 105 can be cleaned by using the water flow discharged from the cleaning port 204, improving the cleaning degree of the toilet.

[0038] Further, the flushing nozzle 20 includes a mounting portion 205 that forms a flushing cavity 201 and a first limiting portion 206 that protrudes from the outer wall of the mounting portion 205. In this embodiment, the radial dimension of the mounting portion 205 matches the inner diameter dimension of the mounting channel 105. The first limiting portion 206 protrudes from the radial end face of the mounting portion 205.

[0039] Further, the first limiting portion 206 elastically abuts against the inner wall of the mounting channel 105. In this embodiment, the flushing nozzle 20 uses the first limiting portion 206 to elastically abut against the inner wall of the mounting channel 105 to provide a pre-tightening force between the flushing nozzle 20 and the mounting channel 105, thereby preventing the flushing nozzle 20 from loosening and also facilitating the insertion fit between the flushing nozzle 20 and the mounting channel 105.

[0040] Specifically, the flushing nozzle 20 further includes a movable portion 207 that connects to the mounting portion 205 and is located within the cleaning port 204, and at least a part of the first limiting portion 206 is connected to the movable portion 207. In this embodiment, as Figure 5 shown, the movable portion 207 is connected to one inner wall of the cleaning port 204 and is spaced from the other inner walls of the cleaning port 204. The cleaning port 204 is formed on the radial side wall of the mounting portion 205. In addition to providing cleaning water flow to the mounting channel 105, the cleaning port 204 also provides a certain movement space for the movable portion 207 (or facilitates the deformation of the movable portion 207), so as to be able to provide a resilience force for the first limiting portion 206 and simplify the structure of the flushing nozzle 20.

[0041] Further, the flushing nozzle 20 includes a plurality of cleaning ports 204 and first limiting portions 206 corresponding to the cleaning ports 204 one by one, and the plurality of cleaning ports 204 are arranged circumferentially around the mounting portion 205. In this embodiment, the plurality of cleaning ports 204 are evenly arranged circumferentially around the mounting portion 205, and preferably four cleaning ports 204 are provided. The plurality of cleaning ports 204 can improve the cleaning effect of the mounting channel 105. Similarly, the number of the first limiting portions 206 is the same as the number of the cleaning ports 204, thereby improving the limiting strength between the flushing nozzle 20 and the mounting channel 105 and preventing the flushing nozzle 20 from loosening.

[0042] Further, the cross-sectional dimension of the mounting portion 205 gradually decreases from the end far from the urinal cavity 101 towards the end close to the urinal cavity 101. In this embodiment, as Figure 5, the outer shape of the installation part 205 is in a wedge-shaped structure, which facilitates the insertion of the flushing nozzle 20 into the installation channel 105. At the same time, since the cross-sectional dimension of the installation part 205 gradually increases in the front-back direction, and the water inlet 203 is located on the side with a larger cross-sectional dimension (i.e., the rear side), it can ensure that the water flow pressure flowing out of the flushing port and the drain port 202 meets the requirements. The size of the gap formed between the installation part 205 and the installation channel 105 gradually decreases in the front-back direction, facilitating the cleaning port 204 to flow into the gap and smoothly flow to the toilet cavity 101 through the installation channel 105.

[0043] In addition, in order to facilitate the insertion between the flushing nozzle 20 and the installation channel 105, one end of the first limiting part 206 close to the toilet cavity 101 is also set to be wedge-shaped.

[0044] Specifically, the toilet cavity 101 includes an inner cavity 1011 and a water channel 1012 communicating with the inner cavity 1011. The flushing nozzle 20 includes a lower flushing port 208 exposed in the inner cavity 1011 and a side flushing port 209 exposed in the water channel 1012. In this embodiment, the lower flushing port 208 discharges water towards the inner cavity 1011, which can flush the wall surface of the inner cavity 1011 and provide sufficient water pressure to discharge the sewage in the toilet cavity 101 through the sewage pipe. Preferably, the flushing nozzle 20 includes two symmetrically arranged side flushing ports 209. The vortices formed by the side flushing ports 209 along the water channel 1012 can provide sufficient water pressure to discharge the sewage in the toilet cavity 101 through the sewage pipe and clean the wall surfaces of the water channel 1012 and the inner cavity 1011.

[0045] Specifically, the axes of both the lower flushing port 208 and the side flushing port 209 are arranged at a certain angle with the axis of the drain port 202. In this embodiment, the drain port 202 can be exposed towards the inner cavity 1011 and / or the water channel 1012, as long as it can form a water curtain after cooperating with the diversion wall 104, thereby improving the cleaning effect of the wall surface of the inner cavity 1011. The lower flushing port 208, the side flushing port 209, and the drain port face different directions respectively, which can achieve a dead-angle-free cleaning of the toilet cavity 101.

[0046] Furthermore, the flushing nozzle 20 further includes a second limiting part 210 connecting the installation part 205. In this embodiment, as Figure 5 , the second limiting part 210 is in an annular structure and is connected to the rear end of the installation part 205.

[0047] Further, the toilet further includes a water supply pipe 30 communicating with the flushing chamber 201 and a seal 40 cooperating with the water supply pipe 30. In this embodiment, the water supply pipe 30 is docked with the water inlet 203, and the water supply pipe 30 communicates with a water supply tank or an external water source, so as to introduce external water flow into the flushing chamber 201. The seal 40 is sleeved on the front end of the water supply pipe 30, and the seal 40 abuts between the radial end face of the water supply pipe 30 and the inner wall of the installation channel 105, ensuring the seal between the water supply pipe 30 and the installation channel 105.

[0048] Further, a limiting step 1051 is provided in the installation channel 105. In this embodiment, the installation channel 105 includes at least two channels with different inner diameter sizes, so as to form the limiting step 1051.

[0049] Further, one end of the second limiting portion 210 abuts against the limiting step 1051, and the opposite end of the second limiting portion 210 abuts against the seal 40. In this embodiment, the seal 40 abuts between the second limiting portion 210 and the water supply pipe 30 along the axial direction Z (i.e., the front-back direction), ensuring the seal between the water supply pipe 30 and the flushing nozzle 20. The opposite ends of the second limiting portion 210 respectively abut against the limiting step 1051 and the seal 40, which can limit the offset of the installation portion 205 along the axial direction Z (i.e., the front-back direction).

[0050] Further, the flushing nozzle 20 further includes an installation portion 205 and a diversion portion 211 connecting the installation portion 205. In this embodiment, as Figure 5 , the diversion portion 211 is located on both sides of the front end of the installation portion 205 and is connected to a part of the edge of the side flushing port 209, so as to guide the water flow flowing out of the side flushing port 209.

[0051] Further, the diversion portion 211 is located between the side flushing port 209 and the diversion wall 104. In this embodiment, the diversion portion 211 is located behind the diversion wall 104 and in front of the side flushing port 209. Thus, after the water flow flowing out of the side flushing port 209 is guided by the diversion portion 211, it smoothly flows to the water channel 1012, avoiding the water flow flowing out of the side flushing port 209 flowing to the diversion wall 104 and interfering with the formation of the water curtain.
