[0003] Under low temperature conditions, since the control device and pipes of a general shower are filled with residual water, when the water condenses into ice, it will expand, causing the water originally filled in the shower pipe and internal channel to expand and squeeze the shower pipe or channel, causing the internal channel of the shower to be cracked, resulting in a reduction in the service life of the shower; although there are some anti-freeze cracking structures at present, they can only solve the problem of unidirectional pressure release, and the anti-freeze cracking effect is poor. Utility Model Content

[0007] Furthermore, the water outlet channel is arranged transversely in the main body.

[0008] Furthermore, the anti-freeze cracking mechanism includes a snap fitting docked on the water outlet channel, a plugging piece that blocks and faces the water outlet channel, and an elastic piece connected between the snap fitting and the plugging piece, wherein the elastic piece is used to provide elastic force for the plugging piece to telescopically move.

[0009] Furthermore, the snap fastener is detachably arranged on the main body, so that the plugging member is correspondingly sealed in the water outlet channel.

DETAILED DESCRIPTION

[0028] Combination Figures 1 to 10 The present embodiment provides a shower with anti-freezing cracking function, including a main body 1, on which a water outlet channel 4 is provided; the water outlet channel 4 is correspondingly provided with an anti-freezing cracking mechanism 11 which can adaptively absorb or release the water pressure in the water outlet channel 4, wherein at least one anti-freezing cracking mechanism 11 is respectively provided along the transverse and longitudinal directions of the water outlet channel to absorb the water pressure in the water outlet channel 4 which increases along the transverse and longitudinal directions when water freezes.

[0029] In the above, the main body 1 is also provided with a cold water channel 3, a hot water channel 2 and a thermostatic valve core 8; the thermostatic valve core 8 is arranged on a path close to the hot water channel 2 and is located at the junction of the hot water channel 2 and the cold water channel 3 with the water outlet channel 4. In addition, the main body 1 is provided with an adjustment mechanism, which flexibly adjusts the amount of cold water or hot water entering the mixing chamber 81 of the thermostatic valve core 8 through the adjustment mechanism, so that the mixed water in the mixing chamber 81 can quickly reach a preset temperature, and provide constant temperature water for users to shower more conveniently and efficiently, and the water volume through the cold water channel 3 and the hot water channel 2 is input into the mixing chamber 81 of the thermostatic valve core 8, which can effectively avoid the occurrence of cold water and hot water mixing.

[0030] In this embodiment, the regulating mechanism is provided in at least one of the cold water channel 3 or the hot water channel 2, and the regulating mechanism is configured to be suitable for inputting more hot water or less cold water into the mixing chamber 81, so that the mixing chamber 81 can quickly provide constant temperature water to the water outlet channel 4 at a preset temperature. Specifically, in one embodiment, the regulating mechanism is provided on the cold water channel 3, and is used to adjust the amount of cold water entering the mixing chamber 81 so that the mixed water quickly reaches the preset temperature of the thermostatic valve core 8. Thus, the total amount of cold water input into the mixing chamber 81 is directly controlled by the regulating mechanism configured in the cold water channel 3, especially in cold winter, by adjusting and controlling less cold water to enter the mixing chamber 81, the proportion of hot water can be larger, and the mixed water in the mixing chamber 81 can quickly rise to the preset temperature.

[0031] It should be noted that in other embodiments, the hot water channel 2 may also be provided with the regulating mechanism to regulate more hot water to enter the mixing chamber 81, so that the proportion of hot water can be larger. Alternatively, the cold water channel 3 and the hot water channel 2 may be provided with regulating mechanisms respectively to control the water inflow outputted by the respective channels, which fall within the protection scope of this case.

[0032] Furthermore, the regulating mechanism is a flow regulating valve 7 with an opening and closing function. In one embodiment, the flow regulating valve 7 has only a closed state and an open state. When it is closed, it directly prevents the channel from entering the mixing chamber 81, thereby closing the input of water. When it is in the open state, the channel directly enters the mixing chamber 81, thereby opening the input of water.

[0033] In another embodiment, the flow control valve 7 has a closed state and an open state with multiple adjustment gears. The amount of water input into the mixing chamber 81 can be more flexibly controlled by adjusting the opening sizes of the different gears.

[0034] like Figure 6 and Figure 7 As shown, in this embodiment, the thermostatic valve core 8 is arranged on the path close to the hot water channel 2, and is located at the junction of the hot water channel 2 and the cold water channel 3 with the water outlet channel 4. Among them, the flow regulating valve 7 is only provided on the path of the cold water channel 3. At this time, after the flow regulating valve 7 is closed, the thermostatic valve core 8 only inputs hot water to discharge water at a constant temperature, and the residual water is discharged from the mixing chamber 81 and the water outlet channel 4. Therefore, after the residual water in the shower controller is discharged, the regulating mechanism is turned on to allow the cold water to start entering the mixing chamber 81 so that the mixed water quickly reaches the preset temperature.

[0035] like Figure 7 and Figure 8As shown, in this embodiment, one end of the main body 1 is connected to the cold water channel 3 to connect to the cold water inlet, and the other end of the main body 1 is connected to the hot water channel 2 to connect to the hot water inlet. In addition, the water outlet channel 4 is divided into multiple water channels along the water outlet direction, and the main body 1 is provided with a water outlet connector 9 connected to the water channel, and a valve core 10 for independently controlling the water outlet of each water channel to the corresponding water outlet connector 9.

[0036] Thus, by carrying out cold water inlet and hot water inlet at opposite ends, the water inlets of the cold water channel 3 and the hot water channel 2 are set away from each other, and the flow regulating valve 7 is used to open and close the cold water channel 3 separately in real time. When not in use, the water inlet of the cold water channel 3 is closed, thereby avoiding the problem of mutual interference of cold and hot water. The flow rate of cold water entering the water outlet channel 4 can be further adjusted, and the input of the cold water inlet flow rate can be adjusted at any time according to different needs to achieve a more suitable temperature use effect.

[0037] In this embodiment, the water outlet channel 4 is arranged transversely in the main body 1, and the cold water channel 3 and the hot water channel 2 are arranged on the left and right sides of the water outlet channel 4 along the water inlet direction. On the one hand, the cold water channel 3 and the hot water channel 2 on the left and right sides are finally connected to the water outlet channel 4, and under the adjustment and control of their respective valve cores, it is ensured that the shower can be thermostatically controlled. On the other hand, the cold water channel 3 is as far away from the hot water channel 2 as possible, which greatly reduces the probability of cold water and hot water interflowing.

[0038] Among them, the flow regulating valve 7 is arranged in the cold water channel 3, and the thermostatic valve core 8 is arranged between the hot water channel 2 and the water outlet channel 4. The thermostatic valve core 8 can automatically adjust the mixing ratio of cold and hot water after the regulating mechanism controls the input water intake, so that the temperature of the mixed water can be automatically maintained at a preset temperature. Obviously, the flow regulating valve 7, the thermostatic valve core 8 and the valve core member 10 are all existing valve core structures, which can implement opening adjustment and opening and closing control in the water channel, and will not be described in detail here.

[0039] In this embodiment, the cold water channel 3 is connected to the cold water end of the thermostatic valve core 8 with a branch 12, the hot water channel 2 is directly connected to the hot water end of the thermostatic valve core 8, and the water outlet end of the thermostatic valve core 8 is connected to the water outlet channel 4. Therefore, such a configuration allows cold water to be input to the thermostatic valve core 8 on the hot water side from a longer distance, and the thermostatic valve core 8 controls the opening size of the cold water side and the hot water side accordingly, thereby providing water at the water outlet end with the required temperature for the user. Among them, the water outlet end of the thermostatic valve core 8 is closer to the water outlet channel 4 than the water outlet end of the flow control valve 7.

[0040] It should be mentioned that when the cold water channel 3 is closed, the shower controller realizes the optimal discharge and energy-saving mode of "zero cold water" input, and utilizes the constant temperature function characteristics of the thermostatic valve core 8 to absolutely give priority to discharging the cold water in the hot water channel 2, so that the outlet water temperature reaches the preset temperature. When the outlet water temperature reaches the set temperature, the thermistor of the thermostatic valve core 8 will automatically close the hot water channel 2. When the cold water in the hot water channel 2 is discharged, the flow regulating valve 7 opens the cold water passage accordingly, and the thermostatic valve core 8 will automatically adjust the water intake ratio of cold and hot water to output mixed water of the corresponding set temperature. This function not only allows consumers to reduce the temperature adjustment time, but also saves the waste of cold water output in the cold water pipeline during the early temperature adjustment, making the thermostatic shower more time-saving and energy-saving.

[0041] like Figure 7 and Figure 8 As shown, in this embodiment, an anti-freezing crack mechanism 11 is correspondingly provided in the water outlet channel 4, and the anti-freezing crack mechanism 11 is configured to absorb or release the water pressure in the water outlet channel 4 adaptively. Among them, multiple anti-freezing crack mechanisms 11 are respectively provided at least in the transverse and longitudinal directions of the water outlet channel 4. Anti-freezing crack mechanisms 11 are correspondingly provided in multiple transverse and longitudinal directions in the water outlet channel 4, and the anti-freezing crack mechanism 11 can adaptively absorb or release the water pressure in the water outlet channel 4, so as to avoid the water in the pipe freezing and bursting the water outlet channel 4 in the main body in a cold environment, causing potential risks such as freezing and cracking of the main body and water leakage of the product, thereby reducing unnecessary economic losses.

[0042] In this embodiment, the anti-freezing crack mechanism 11 includes a snap-fitting member 13 docked at one end of the water outlet channel 4, a plugging member 14 that blocks and faces the water outlet channel 4, and an elastic member 15 connected and arranged between the snap-fitting member 13 and the plugging member 14, and the elastic member 15 is used to provide elastic force for the plugging member 14 to telescopically move. Specifically, by detachably arranging the snap-fitting member 13 on the main body, the plugging member 14 is correspondingly blocked in the water outlet channel 4, and the plugging member 14, under the action of the elastic member 15, can press the plugging member 14 to compress the elastic member 15 after the water pressure in the water outlet channel 4 increases, and at this time, energy is stored to absorb the increased water pressure to prevent the pipe from bursting. After the water pressure in the water outlet channel 4 decreases, the elastic member 15 releases the stored energy to reach the initial state, thereby realizing the anti-cracking design of the shower pipe.

[0043] Furthermore, the snap-fitting member 13 is detachably arranged on the side of the main body 1, and the elastic member 15 is configured as an elastic rubber abutting between the snap-fitting member 13 and the plug member 14. The plug member 14 is movably arranged in the water outlet channel 4, and a sealing ring 16 is arranged on the plug member 14. The elastic rubber has a smaller deformation amplitude and is more suitable for absorbing and releasing the water pressure in the pipeline. The sealing member serves the purpose of watertight sealing on the one hand, and also provides resistance to the movement of the plug member 14 in the channel on the other hand. When the plug member 14 is squeezed by the expansion of the water volume when the water freezes (or when the external pressure is greater than 0.6Mpa), the built-in elastic rubber is compressed accordingly, and the corresponding compressed volume is fully released, thereby reducing the pressure applied to the pipeline due to the expansion of the water volume when the water freezes, and preventing damage or bursting of the pipeline. When the ice melts (or the external pressure is less than 0.6Mpa), the built-in elastic rubber returns to its initial state, thereby ensuring the permanence and applicability of its function. In other embodiments, the elastic member 15 may also adopt an elastic structure similar to a spring.

[0044] The anti-freezing crack mechanism 11 is arranged on the end of the water outlet channel 4 near the water outlet end of the thermostatic valve core 8. Therefore, the anti-freezing crack mechanism 11 is arranged in the water inlet direction of the water outlet channel 4 to further improve the effectiveness of water pressure absorption and release in the channel. It should be noted that the structure of the anti-freezing crack device can also adopt other existing forms to achieve pressure release in the horizontal and vertical directions.

[0045] like Figures 8 to 10 As shown, in this embodiment, a filter mechanism 17 is further provided on the path of the cold water channel 3 and the hot water channel 2, and the filter mechanism 17 is detachably configured on the main body 1 and is blocked at the cross section of the cold water channel 3 or the hot water channel 2. Therefore, the filter mechanism 17 is provided on both the cold water channel 3 and the hot water channel 2, which can greatly reduce the impact of impurities in the water on the water entry of the shower, and improve the shower experience of the user.

[0046] Furthermore, the filter mechanism 17 includes a filter core 18, a screw connection 19 and an operating part 20. The main body 1 is correspondingly provided with a threaded hole 21 that matches the screw connection 19, and the operating part 20 is used to screw the screw connection 19 into the threaded hole 21 so that the filter core 18 is inserted into the assigned channel. The operating part 20 of the filter mechanism 17 facilitates the user to directly screw the screw connection 19 onto the threaded hole 21 of the main body 1, which is convenient for disassembly, replacement and maintenance. The filter core 18 is inserted into the cold water channel 3 or the hot water channel 2, and the filtering effect is particularly good.

[0047] The filtering mechanism 17 is respectively arranged at the water inlet front end of the cold water channel 3 and the water inlet front end of the hot water channel 2 of the main body 1. Specifically, the filtering mechanism 17 is arranged in the channel close to the respective valve cores and arranged at the back of the main body 1. On the one hand, the filtering mechanism 17 is arranged close to the valve core to lengthen the filtering path. On the other hand, the filtering mechanism 17 is arranged at the back of the shower, which does not affect the overall appearance and is convenient for hiding the filtering mechanism 17 to avoid pollution and damage.

[0048] like Figures 2 to 7 As shown, in this embodiment, the flow regulating valve 7 is longitudinally arranged on the front end side of the main body, the thermostatic valve core 8 is transversely arranged on the side of the main body, and the cold water inlet connector 5 and the hot water inlet connector 6 are respectively longitudinally arranged on the rear end side of the main body.

[0049] Among them, multiple valve core parts 10 are arranged in parallel on the same side as the flow regulating valve 7, and multiple water outlet joints 9 are correspondingly arranged on the upper and lower end surfaces of the main body, which are used to respectively perform water outlets of different functions. Specifically, a water outlet joint 9 is provided on the upper end surface of the main body, and one valve core part 10 is used to control the water outlet joint 9 to discharge water to the top spray. Two water outlet joints 9 are provided on the lower end surface of the field main body, one valve core part 10 is used to control one water outlet joint 9 to discharge water to the shower head, and one valve core part 10 is used to control the water outlet joint 9 to discharge water to the faucet.

[0050] Preferably, the cold water inlet connector 5 and the hot water inlet connector 6 are configured as filtering curved pipe fittings, and the water outlet connector 9 is configured as a straight pipe fitting. Obviously, the curved pipe fitting is more suitable for compact external connection to the cold and hot water pipelines. The straight pipe fitting is conducive to directly discharging water from the shower for daily use by users.

[0051] In this embodiment, the main body 1 is a flat structure, corresponding to the connection to the external water system. The main body 1 is suitable for various types of water outlet devices, and such a structural shape is more conducive to the assembly and maintenance of the structural parts, greatly improving the core competitiveness of the product.

[0052] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
