Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of sanitary wares, and relates to an induction water outlet switching structure. BACKGROUND

[0002] A shower is the most commonly used showering device in people's daily life, and with the continuous improvement of people's living standards, the comfort and convenience of the showering process are increasingly required. For example, in winter, although most users have a water heater at home, a large amount of cold water remains in the pipeline between the water heater and the shower, and people often need to pre-discharge the cold water remaining in the pipeline before showering, and determine whether it is suitable for showering by continuously manually trying the water temperature of the water outlet. It is inconvenient to use.

[0003] Therefore, people have designed a cold water discharge switching valve core, and have applied for a Chinese patent with the application number 201922055493.X and the publication number CN211449751U. The cold water discharge switching valve core comprises a body and a switching assembly, the body is provided with a water inlet channel and a plurality of water outlet channels, and the switching assembly is movably connected to the body to switch the communication between the water outlet channels and the water inlet channel. A cold water discharge assembly is arranged in a first water outlet channel of the plurality of water outlet channels, the cold water discharge assembly comprises a temperature sensing bag, a sealing member and an elastic member, the temperature sensing bag comprises a first end, a second end and a connecting portion connecting the first end and the second end, and has a heat-sensitive characteristic, and the first end is configured to be fixed with the first water outlet channel, so that the second end and the connecting portion form an output portion, and the output portion expands along the length direction of the temperature sensing bag when heated. The cold water discharge switching valve core has three water outlet channels, wherein when water flows into the first water outlet channel, the temperature sensing bag can expand in the length direction according to the water temperature, such as cold water, and the like, and when the water is hot, the temperature sensing bag expands and blocks the first water outlet channel, giving the user an intuitive reminder to discharge hot water.

[0004] However, in actual use, the inlet and outlet positions of the pipeline, valve body, shower device, faucet and other structures are in the form of a circular pipe, and the existing temperature sensing bag is in the form of a cylinder as a whole. In order to adapt to the existing use environment and matching structure, the overall structure of the cold water discharge switching valve core and the plurality of water outlet channels inside the valve core can only be designed in the form of a circle. Three water outlet channels are arranged around the axis in the valve core in the form of a cylinder, leaving a large space between each water outlet channel and between the water outlet channel and the outer side of the valve core, resulting in a large amount of space waste, greatly reducing the water discharge amount of each water outlet channel, especially the water outlet channel with the temperature sensing bag, which occupies most of the space in the water outlet channel, further reducing the water discharge amount, and it is difficult to meet the use requirements of some users who require a high water discharge amount.

[0005] To address this problem, the conventional approach for those skilled in the art is to adjust the flow rate by increasing the orifice diameter of one or more outlets, especially those with temperature sensors, while decreasing the orifice diameter of outlets used less frequently, based on the user and the frequency of use of each outlet. While this method can increase the flow rate to some extent, the increase is limited without altering the valve core volume. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an induction-based water outlet switching structure, which solves the problem of low water output from the existing cooling outlet switching valve core.

[0007] The objective of this invention can be achieved through the following technical solutions:

[0008] A water outlet switching structure includes a main body with an inlet end and an outlet end, and an inlet seat with an inlet connected to the inlet end. The outlet end of the main body has a recessed switching hole, and a temperature sensing component and an elastic element are disposed inside the switching hole. A drain hole communicating with the switching hole is provided through the side of the main body. The main body is characterized by having a cylindrical outer shell fitted on its outer side, and an outlet gap being formed between the inner side of the outer shell and the outer side of the main body. The inlet seat enables the switching hole or the outlet gap to communicate with the inlet. The temperature sensing component can move within the switching hole and connect the opening of the switching hole or the drain hole with the inlet of the inlet seat.

[0009] In use, this sensor-activated water outlet switching structure connects the inlet of the inlet base to the inlet pipe, and aligns the outlet gap with the opening of the switching hole to create the outlet channel. If pre-draining of cold water is required, the inlet of the inlet base is connected to the switching hole. The temperature-sensing component senses the temperature of the incoming water. When the water temperature is low, indicating residual cold water in the pipe, the temperature-sensing component does not deform. Under the elastic force of the elastic element, it blocks the opening of the switching hole, connecting the drain hole with the inlet, allowing cold water to drain from the drain hole on the side of the main body. When the water temperature rises, the temperature-sensing component expands, overcoming the elastic force of the elastic element, blocking the drain hole and connecting the opening of the switching hole with the inlet. Hot water then flows out from the outlet end of the main body with the switching hole opening for user use. When the pre-draining function is not needed, the inlet is connected to the outlet gap between the main body and the outer casing. In this case, both hot and cold water flow out from the outlet gap without passing through the temperature-sensing component.

[0010] In this induction water outlet switching structure, there are two water outlet channels: a switching hole and a water outlet gap. The two are separated only by the annular sidewall on the main body, which maximizes the water-passing area. The sufficiently large switching hole is used to place the temperature sensing component. Even if the temperature sensing component occupies part of the cross section inside the switching hole, there can still be a large water output, thus increasing the water output.

[0011] In the induction water outlet switching structure, the water inlet end of the main body has a water passing hole I connecting the water inlet and the switching hole and a water passing hole II connecting the water inlet and the water outlet gap, the water inlet end of the main body has a protruding protruding part, and the water passing hole I and the water passing hole II are partially arranged in the protruding part. The switching hole is arranged in the water outlet end, and the water passing hole I and the water passing hole II are arranged in the water inlet end, which are staggered, reducing the influence of the water passing hole I and the water passing hole II on the radial size of the switching hole, and at the same time, without affecting the water outlet gap, the water passing area of the water passing hole I and the water passing hole II is expanded as much as possible by the expansion of the protruding part, and the water passing amount is increased.

[0012] In the induction water outlet switching structure, the water inlet end of the main body has a water inlet end, and the water inlet end has a plurality of protruding cylindrical support cylinders, the plurality of support cylinders are arranged in the axial direction of the shell, and the outer side of the support cylinder can abut against the inner wall of the shell. The radial position of the shell is limited by the plurality of support cylinders, which ensures the stability of the water outlet gap in the shell and further ensures the stability of the water outlet amount, and at the same time, the inner hole of the support cylinder can also supply water, which reduces the obstruction to the waterway and further ensures the water outlet amount.

[0013] In the induction water outlet switching structure, the switching hole includes a large hole and a small hole connected to each other, the hole diameter of the small hole is smaller than that of the large hole, and the large hole is closer to the end of the water outlet end of the main body than the small hole, the drain hole is arranged through the side wall of the small hole, the inner wall of the main body at the connection of the large hole and the small hole forms an annular shoulder, and the outlet of the water passing hole I is connected to the side wall of the large hole. The inner end of the switching hole is the small hole with a smaller hole diameter, which can provide space for the water passing hole I, ensure the hole diameter and water passing amount of the water passing hole I, and at the same time, the shoulder formed between the large hole and the small hole can facilitate the sealing of the drain hole by the temperature sensing assembly.

[0014] In the induction water outlet switching structure, the large hole, the small hole, the water passing hole I and the water passing hole II are all straight holes, and the axial directions of the four holes are consistent with the axial direction of the shell, the water passing hole I is arranged adjacent to the small hole, and the water passing hole II is arranged adjacent to the small hole. The axial directions of the holes are consistent, and the adjacent arrangement can maximize the use of the space in the main body and ensure the water outlet amount.

[0015] In the above-mentioned induction water switching structure, the temperature sensing assembly comprises a temperature sensing bag with a columnar deformation part and a ring-shaped sealing member I, the elastic member is arranged in the small hole, the sealing member I is sleeved on the outer side of the temperature sensing bag at the end of the elastic member I, and when the temperature sensing bag moves against the elastic force of the elastic member, the sealing member I can abut against the shoulder and block the small hole. When the sealing member I abuts against the shoulder, the end of the temperature sensing bag at the end of the elastic member I has a spacing with the bottom surface of the small hole. The temperature sensing bag blocks the small hole by abutting against the shoulder through the sealing member I of the side part, thereby blocking the water outlet hole and the water passing hole I arranged on the side wall of the small hole, and the sealing is more stable. Meanwhile, most sealing rings are made of rubber or silica gel material, and the texture is relatively soft. Even if the temperature of water is slightly increased after the small hole is blocked, the temperature sensing bag can compress the sealing member I to continue to deform into the small hole, thereby further enhancing the sealing effect and effectively avoiding the situation that the deformation of the temperature sensing bag is limited to cause failure or damage.

[0016] In the above-mentioned induction water switching structure, the temperature sensing assembly further comprises a ring-shaped sealing member II, a sealing seat is fixed at the opening of the switching hole of the main body, the outer end of the deformation part abuts against the sealing seat, the sealing member II is sleeved and fixed on the outer side of the temperature sensing bag at the end of the sealing seat, and when the temperature sensing bag moves under the elastic force of the elastic member, the sealing member I can abut against the sealing seat and block the switching hole.

[0017] In the above-mentioned induction water switching structure, the outer shell does not block the water outlet hole, a cylindrical adjusting cylinder is further sleeved on the outer side of the main body at the water outlet hole, and the adjusting cylinder can rotate circumferentially relative to the main body. The adjusting cylinder is arranged adjacent to the outer shell, and one side of the adjusting cylinder has a water outlet hole for connecting the water outlet hole and the outer side of the adjusting cylinder. The outer shell does not block the water outlet hole, so that the water outlet of the water outlet hole and the water outlet of the water gap are in different directions, and the water outlet of the water outlet hole can be adjusted in direction by circumferentially rotating the adjusting cylinder.

[0018] In the above-mentioned induction water switching structure, the outer side of the main body has a protruding elastic deformation clamping member, the clamping member is in a sheet shape, one end of the clamping member is fixed to the main body, and the other end is folded towards the outer shell. The inner side of the outer shell has a recessed clamping hole, and the clamping member is clamped in the clamping hole. During assembly, the outer shell is sleeved on the outer side of the end part of the water outlet end of the main body and is pushed in the axial direction. The protruding clamping member is extruded by the outer shell, so that the clamping member is elastically deformed towards the main body. When the outer shell is pushed to the position where the clamping hole corresponds to the clamping member, the clamping member is popped out and clamped in the clamping hole, thereby realizing the fixation between the outer shell and the main body.

[0019] In the above-mentioned induction water switching structure, the water inlet base is rotatably connected to the water inlet end, one end of the water inlet base towards the main body has a protruding limiting block, the water inlet end of the main body has a recessed limiting slot in a circular arc shape, the limiting block extends into the limiting slot and can move along the limiting slot, and when the limiting block moves to the two ends of the limiting slot respectively, the water inlet is in communication with the water passing hole one and the water passing hole two respectively. The communication positions of the two water passing holes are limited by the cooperation of the circular arc limiting slot and the limiting block, the position after switching is guaranteed to be directly opposite, and the water output during use is guaranteed.

[0020] Compared with the prior art, the induction water switching structure has two water outlet channels, namely the switching hole and the water outlet gap, which are separated only by the annular side wall of the main body, which maximizes the use of the water passing area. Even if the temperature sensing assembly occupies part of the cross section in the switching hole, there is still a large water output improvement effect. BRIEF DESCRIPTION OF DRAWINGS
