Description

Technical Field

[0001] This utility model generally relates to the field of bathroom equipment technology, and more specifically, to a flushing connection structure and a toilet. Background Technology

[0002] To accommodate the need for a flush-before-wash function, most smart toilets use a valve to control the flushing process. The valve supplies water to the toilet bowl, enabling the flushing action. Existing nozzles are typically made of individually molded plastic or metal connectors and fixed to the spray hole at the bottom of the toilet bowl, connected to the valve via a connecting pipe.

[0003] Since the valve body and nozzle are supplied by different vendors, it is necessary to coordinate their diameters during procurement, and even customize the models. Otherwise, if the valve body diameter and nozzle diameter are inconsistent, the connecting pipe used for connection will need to be designed with a variable diameter, or even a disassembled design, which is complex to manufacture and has high modification costs.

[0004] Therefore, when purchasing, it is often necessary to consider the compatibility between the valve body and the nozzle diameter. Even if two suppliers offer the most cost-effective products of the same quality, the lack of compatible models between the suppliers makes them difficult to use, hindering the control and reduction of material costs in production. Therefore, there is an urgent need for a connection structure that allows for seamless connection between valve bodies and nozzles of different diameters to solve the above problems.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0036] like Figures 1-6 As shown, this embodiment provides a flushing connection structure, including a valve body 400 and a nozzle 100. The valve body 400 is connected to the nozzle 100 via a pipe 300. The valve body 400 has a valve port 401, and the pipe 300 connects the valve port 401 and the nozzle 100. It also includes a connector 200 for connecting the pipe 300. The nozzle 100 is detachably connected to the connector 200 and then connected to the pipe 300. It is understood that the diameters at both ends of a conventional pipe 300 are the same. Therefore, the diameter of the nozzle 100 must match the diameter of the valve port 401 of the valve body 400 to ensure a seamless connection between the nozzle 100 and the valve body 400 at both ends of the pipe 300. In this embodiment, when the nozzle 100 needs to be connected to a valve body 400 with a different diameter, a connector 200 that matches the diameter of the valve port 401 of the valve body 400 is first selected, the connector 200 is detachably installed on the nozzle 100, and then the connector 200 is connected to the valve port 401 of the valve body 400 so that the nozzle 100 and the valve body 400 can be connected without obstruction.

[0037] In some embodiments, the conduit 300 is a pipe of the same diameter or a pipe with a gradually changing diameter. It is understood that the diameter of the conduit 300 used to connect the connector 200 is not limited, that is, it can be a conventional conduit 300 with a constant diameter or a special-shaped pipe with a gradually changing diameter.

[0038] In some embodiments, such as Figures 2-5 As shown, the nozzle 100 has a connection port 102, and the diameter of the valve port 401 is different from the diameter of the connection port 102 of the nozzle 100. In this embodiment, when the diameter of the valve port 401 is different from the diameter of the connection port 102 of the nozzle 100, by using a corresponding type of connector 200, the difference in diameter can be ignored, and the two ends of the pipeline 300 can be connected to the valve port 401 of the valve body 400 and the connection port 102 of the nozzle 100 without obstruction.

[0039] In some embodiments, such as Figures 3-5 As shown, by adding a connector 200, the diameter D2' of the connector 200 can be adjusted according to the actual size of the main punch valve port 401 diameter D1 of the valve body 400. This allows the main punch connecting pipe 300 to always maintain a consistent cross-sectional area while connecting the valve body 400 with a diameter of D1 and the nozzle 100 with a diameter of D2, where D1 ≠ D2. This facilitates the forming and processing of the main punch connecting pipe 300 and reduces costs.

[0040] In some embodiments, the connector 200 is a sleeve, with one of the pipe 300 and the nozzle 100 connection port 102 sleeved on the outer wall of the connector 200, and the other of the pipe 300 and the nozzle 100 connection port 102 sleeved on the inner wall of the connector 200. The diameter of the pipe 300 is different from the diameter of the nozzle 100 connection port 102.

[0041] In some embodiments, the nozzle 100 can be aimed at the toilet bowl drain outlet, and when the valve body 400 is opened, the nozzle 100 can spray onto the drain outlet.

[0042] In some embodiments, such as Figure 4 As shown, the connector 200 is threaded or snap-fitted to the nozzle 100. In this embodiment, the detachable connection between the nozzle 100 and the connector 200 is a threaded connection. That is, the nozzle 100 and the connector 200 are provided with mating internal and external threads 103, and the connector 200 is screwed onto one end of the nozzle 100. However, this embodiment is only a preferred embodiment. In other embodiments, the detachable connection between the nozzle 100 and the connector 200 can also be any existing detachable connection method such as magnetic sleeve, binding, or locking.

[0043] In some embodiments, such as Figures 1-4As shown, the connector 200 has a clamping part 210 and a guide part 220. The clamping part 210 is threadedly connected to the nozzle 100. The pipeline 300 is introduced into the clamping part 210 through the guide part 220 and connected to the outer periphery of the clamping part 210. The outer periphery of the guide part 220 is provided with a guide cone surface 221. The narrow opening of the guide cone surface 221 faces outward, and the wide opening of the guide cone surface 221 is provided with an anti-detachment stop 222 protruding from the periphery of the clamping part 210. In this embodiment, the connector 200 is a ring-shaped part. The clamping part 210 of the connector 200 is provided with an internal thread 211, and the nozzle 100 is provided with an external thread 103. During assembly, the nozzle 100 is screwed into the connector 200. After tightening, the stop 201 provided in the connector 200 presses against the left end of the nozzle 100. During assembly, the port of the hose 300 is fitted over the guide portion 220 of the connector 200 and pressed into the clamping portion 210 on one side of the anti-detachment stop 222 of the guide portion 220 along the narrow opening of the guide cone surface 221. The anti-detachment stop 222 protruding from the clamping portion 210 inside the port of the hose 300 clamps the hose 300, preventing it from detaching, thus completing the connection of the hose 300, connector 200, and nozzle 100. In other embodiments, waterproof adhesive can be applied to the outer periphery of the clamping portion 210 of the connector 200 to bond the hose 300 to it.

[0044] In some embodiments, such as Figures 1-4 As shown, a sealing ring 110 is provided between the connector 200 and the nozzle 100; a nut 120 is provided on the nozzle 100 for fixing the installation position, and an outer edge 101 is provided at the end of the nozzle 100. The outer edge 101 cooperates with the nut 120 to fix the nozzle 100 in the installation position. It can be understood that the sealing ring 110 is used to enhance the sealing performance between the connector 200 and the nozzle 100. Specifically, an annular groove 104 can be provided in the connecting section of the nozzle 100 for connecting the connector 200 to install the sealing ring 110. There can be multiple pairs of annular grooves 104 and sealing rings 110, and they are arranged along the length direction of the nozzle 100. In this embodiment, there are two pairs of annular grooves 104 and sealing rings 110. The nut 120 can also be screwed onto the nozzle 100 by means of a threaded connection. During installation, the nut 120 cooperates with the outer edge 101 at the end of the nozzle 100 to clamp and fix the nozzle 100 at the spray hole at the bottom of the toilet bowl 500. A washer 130 can also be provided between the nut 120 and the outer edge 101 of the nozzle 100. A connector 200 is screwed on the other side of the nut 120.

[0045] In some embodiments, such as Figures 5-6 As shown, valve body 400 can be electronic or mechanical.

[0046] According to another aspect of this disclosure, such as Figure 6As shown, a toilet is provided, including the flushing connection structure described above. The valve body 400 is a reversing valve, with one path connected to the nozzle 100 of the main flushing channel and the other path connected to the brush ring channel 402. It can be understood that the flushing connection structure is specifically the connection structure between the reversing valve and the nozzle 100. It provides a more stable, faster, and more compatible connection solution for the reversing valve pipeline 300 to the nozzle 100, and is applicable to various electronic or mechanical valve bodies 400, offering good versatility and easy promotion and application. In this embodiment, the flushing connection structure is specifically applied to the toilet 500 product, used for unobstructed connection of the pipelines 300 between the various components inside the toilet 500. In other embodiments, the flushing connection structure described in this application can also be used in shower water heaters, oil and gas equipment, spraying equipment, and other devices where internal and external components are connected by pipelines 300.

[0047] It should be understood that the various examples described above can be utilized in multiple directions (e.g., tilted, inverted, horizontal, vertical, etc.) and in multiple configurations without departing from the principles of this invention. The embodiments shown in the accompanying drawings are merely examples of effective application of the principles of this invention, and the invention is not limited to any specific details of these embodiments.

[0048] Of course, upon careful consideration of the above description of the representative embodiments, those skilled in the art will readily understand that various modifications, additions, substitutions, deletions, and other changes can be made to these specific embodiments, and that such changes are within the scope of the principles of this invention. Therefore, the foregoing detailed description should be clearly understood as being given by way of illustration and example only, and the spirit and scope of this invention are defined solely by the appended claims and their equivalents.
