Description

Technical Field

[0001] The present invention relates to a sanitary device for toilets, in particular to a nozzle for a toilet and a toilet. Background Art

[0002] An existing toilet adopts a side flushing method. Specifically, mounting holes are provided at the top of the inner wall of the toilet bowl, and nozzles are installed in the mounting holes. The front end of the nozzle extends out of the mounting hole and is provided with a flange plate that abuts against the inner wall of the toilet bowl to achieve positioning during installation. The water spraying holes of the nozzle penetrate through the front surface of the nozzle, and the flushing water rushes out from the water spraying holes and then flows along the inner wall of the toilet bowl to achieve flushing. Although the inner wall of the toilet bowl can be flushed and can remain clean after long-term use, the position where the flange plate is located, including the front end face and the outer peripheral side face of the flange plate, and the inner wall of the toilet bowl that abuts against the flange plate cannot be flushed. Also, since the installation position of the nozzle is basically a hidden design and can only be cleaned when the user specifically cleans it, it is likely to get dirty after long-term use. Summary of the Invention

[0003] One of the purposes to be achieved by the present invention is to provide a nozzle for a toilet that can self-clean the area where the flange plate of the nozzle is located when flushing the toilet bowl.

[0004] To achieve the above purpose, the present invention adopts the following technical solution: A nozzle for a toilet includes a nozzle body that can be installed on the toilet. A through water outlet hole is provided in the nozzle body. The rear end of the nozzle body is used to connect to a water inlet pipe. The front end of the nozzle body is provided with a flange plate that can abut against the inner wall of the toilet bowl. The front end face of the flange plate is provided with a main water spraying port that communicates with the water outlet hole. The outer peripheral side face of the flange plate is provided with a secondary water spraying port for self-cleaning the area where the flange plate is located, and the secondary water spraying port communicates with the water outlet hole.

[0005] As a preferred solution, the secondary water spraying port is located above the flange plate.

[0006] As a further preferred solution, the flange plate includes a first part and a second part. The second part is located above the first part. The main water spraying port is located in the first part. The second part is provided with a branch water outlet hole that communicates with the water outlet hole. The secondary water spraying port is located on the upper edge side face of the second part and communicates with the branch water outlet hole.

[0007] As a further preferred solution, the first part is integrally formed or fixedly connected with the nozzle body, and the second part is separately formed and then fixedly connected with the nozzle body; or, the first part and the second part are integrally formed or fixed into one body and then fixedly connected with the nozzle body.

[0008] As a further preferred solution, the second part includes an axial part detachably connected to the nozzle body and a radial part protruding upward relative to the axial part. The branch water outlet holes are located in the axial part, and the auxiliary water spray openings are located in the radial part. The nozzle body is provided with an insertion hole that cooperates with the axial part, and the insertion hole communicates with the water outlet holes.

[0009] As a preferred solution, the auxiliary water spray openings are distributed on the entire outer circumference of the flange.

[0010] As a preferred solution, the flange includes a first part and a second part. The second part is located on the front side of the first part. The second part is provided with a main hole and an auxiliary hole that both communicate with the water outlet holes. The main hole penetrates through the second part to form a main water spray opening. The auxiliary water spray openings are located on the outer circumference of the second part and communicate with the auxiliary holes. The first part is located on the nozzle body.

[0011] As a further preferred solution, the first part is integrally formed with the nozzle body, and the second part is fixedly connected to the nozzle body.

[0012] As a further preferred solution, the spraying direction of the auxiliary water spray openings is radial relative to the nozzle body; or, a retaining rib that blocks the auxiliary water spray openings in the radial direction is provided outside the auxiliary water spray openings, and a fine water spray slit for forming a water spray curtain is formed between the retaining rib and the second part.

[0013] The present invention also provides a toilet, including a toilet bowl and a nozzle installed on the top of the toilet bowl. The nozzle is the toilet nozzle in any of the above technical solutions.

[0014] After adopting the above technical solutions, the present invention has the following advantages: Since the auxiliary water spray openings are provided on the outer peripheral side of the flange, when flushing the toilet bowl, in addition to spraying out from the main water spray opening, a part of the flushing water will also spray out from the auxiliary water spray openings. After the nozzle is installed on the toilet, the water sprayed out from the auxiliary water spray openings can not only flush the inner wall of the toilet bowl that abuts against the flange, but also impact the inner wall of the toilet bowl located on the side of the flange. The water sprayed upward will fall back to flush the flange, thereby realizing self-cleaning of the area where the flange of the nozzle is located. It can not only prevent dust from accumulating on the flange and the inner wall of the toilet bowl at the corresponding position, but also clean the dirt on the flange and the inner wall of the toilet bowl at the corresponding position, so that the flange and the inner wall of the toilet bowl at the corresponding position can still maintain good cleanliness after long-term use.

[0029] Embodiment 1:

[0030] The present invention provides a nozzle for a toilet, as Figures 1 to 4 shown, which includes a nozzle body 1 that can be installed on a toilet 9. A through water outlet hole 100 is provided in the nozzle body 1. The rear end of the nozzle body 1 is used to connect to a water inlet pipe. The front end of the nozzle body 1 is provided with a flange 11 that can abut against the inner wall 900 of the toilet bowl. A main water spray opening 101 communicating with the water outlet hole 100 is provided on the front end face 1101 of the flange 11. An auxiliary water spray opening 102 for self-cleaning of the flange 11 is provided on the outer peripheral side surface 1102 of the flange 11. The auxiliary water spray opening 102 communicates with the water outlet hole 100.

[0031] Since the secondary water spray opening 102 is provided on the outer peripheral side surface 1102 of the flange 11, when flushing the toilet bowl, in addition to the flushing water spraying out from the main water spray opening 101, a part of the water will also spray out from the secondary water spray opening 102. After the nozzle is installed on the toilet, the water spraying out from the secondary water spray opening 102 can not only flush the inner wall of the toilet bowl that abuts against the flange, but also impact the inner wall of the toilet bowl located on the side of the flange. The water spraying upwards will fall back to flush the flange, thereby realizing self-cleaning of the area where the flange of the nozzle is located, which can not only prevent dust from accumulating on the flange and the inner wall of the toilet bowl at the corresponding position, but also clean the dirt on the flange and the inner wall of the toilet bowl at the corresponding position, so that the flange and the inner wall of the toilet bowl at the corresponding position can still maintain good cleanliness after long-term use.

[0032] In some special cases, at the position where the nozzle is installed, the distance between the flange 11 and the inner wall of the toilet bowl is relatively far or the angle is not good. After the water spraying out from the secondary water spray opening 102 impacts the inner wall of the toilet bowl, it cannot fall back to the flange 11 well. Therefore, to increase the applicable range of the nozzle, in this embodiment, it is preferably designed that the secondary water spray opening 102 is located above the flange 11. In this way, after the flushing water sprays out from the secondary water spray opening 102, it will fall back to the flange 11 under the action of gravity, and the front end surface 1101 and the outer peripheral side surface 1102 of the flange 11 can be cleaned.

[0033] In addition to machining the secondary water spray opening 102 on the integrally formed flange 11, for the convenience of molding, the structure as shown in Figures 4 to 6 can also be adopted. The flange 11 includes a first part 111 and a second part 112. The second part 112 is located above the first part 111. The main water spray opening 101 is located in the first part 111. The second part 112 is provided with a branch water outlet hole 103 communicated with the water outlet hole 100. The secondary water spray opening 102 is located on the upper edge side surface of the second part 112 and is communicated with the branch water outlet hole 103. In this embodiment, the first part 111 is integrally formed with the nozzle body 1, and the second part 112 is formed separately and then connected and fixed to the nozzle body 1. Since the secondary water spray opening 102 is relatively small, if it is blocked, it can be disassembled and cleaned separately. Specifically, the second part 112 includes an axial part 1121 detachably connected to the nozzle body 1 and a radial part 1122 protruding upwards relative to the axial part 1121. The branch water outlet hole 103 is located in the axial part 1121, and the secondary water spray opening 102 is located in the radial part 1122. The nozzle body 1 is provided with a jack 104 cooperating with the axial part 1121, and the jack 104 is communicated with the water outlet hole 100. In addition, to reduce the molding difficulty, the secondary water spray opening 102 is formed by the radial part 1122 fitting with the first part 111. Specifically, a groove 1120 is provided on the radial part 1122, and the first part 111 covers the groove 1120 to form the secondary water spray opening 102. Of course, the secondary water spray opening 102 can also be directly formed on the radial part 1122.

[0034] Understandably, the first part 111 can also be connected and fixed to the nozzle body 1. In addition, it is also possible to select that the first part 111 and the second part 112 are integrally formed or fixed together and then connected and fixed to the nozzle body 1.

[0035] Embodiment 2:

[0036] In this embodiment, Figures 7 to 10 as shown.

[0037] To improve the cleaning effect, the auxiliary water spray openings 102 can be designed to be distributed on the entire outer circumference of the flange 11.

[0038] In this embodiment, the flange 11 is also designed to include a first part 111 and a second part 112. The second part 112 is located on the front side of the first part 111. The second part 112 is provided with a main hole 1123 and an auxiliary hole 1124 that are both communicated with the water outlet hole 100. The main hole 1123 penetrates through the second part 112 to form a main water spray opening 101. The auxiliary water spray opening 102 is located on the outer circumference of the second part 112 and is communicated with the auxiliary hole 1124. The first part 111 is located on the nozzle body 1.

[0039] For convenient molding, it can be selected that the first part 111 is integrally formed with the nozzle body 1, and the second part 112 is connected and fixed to the nozzle body 1. In this embodiment, the formation method of the auxiliary water spray opening 102 is similar to that in Embodiment 1. That is, a groove 1120 is formed on the second part 112, and the first part 111 covers the groove 1120 to form the auxiliary water spray opening 102. Of course, the auxiliary water spray opening 102 can also be directly formed on the second part 112.

[0040] In order to make the water spray uniform, the spraying direction of the auxiliary water spray opening 102 can be designed to be radial with respect to the nozzle body 1.

[0041] The content not described in this embodiment can be referred to Embodiment 1.

[0042] Embodiment 3:

[0043] In this embodiment, Figures 11 to 13 as shown.

[0044] On the basis of the second embodiment, in order to further improve the cleaning effect, a retaining rib 1111 that radially blocks the secondary water spray outlet 102 is provided outside the secondary water spray outlet 102. A fine water spray slit 105 for spraying a water curtain is formed between the retaining rib 1111 and the second part 112. The retaining rib 1111 can change the water spray direction of the secondary water spray outlet 102, and the front end face 1101 of the flange 11 can be directly rinsed without relying on the rebound of the water flow on the inner wall of the toilet bowl. Moreover, the fine water spray slit 105 can spray a water curtain, increasing the cleaning area. In this embodiment, the retaining rib 1111 is provided on the first part 111, and the fine water spray slit is obtained by an assembly method. Of course, the retaining rib 1111 can also be formed on the second part 112, and the fine water spray slit is obtained by a forming method.

[0045] The fine water spray slits 105 in this embodiment can be distributed at intervals from the secondary water spray outlets 102 in the second embodiment.

[0046] The retaining rib in this embodiment can also be incorporated into the first embodiment.

[0047] For the content not described in this embodiment, reference can be made to the second embodiment.

[0048] Embodiment Four:

[0049] As Figure 1 shown, the present invention further provides a toilet 9, including a toilet bowl 90 and a nozzle installed on the top of the toilet bowl 90. The nozzle is the toilet nozzle in any of the above embodiments.

[0050] The installation and fixation method of the nozzle can adopt common methods such as nuts, buckles, or interference fits. For example, in the present invention, external threads are provided on the outer periphery of the nozzle body, and the nozzle body passes through the toilet bowl and is connected to a nut to achieve installation and fixation.

[0051] In addition to the above preferred embodiments, the present invention has other implementation manners.
