[0002] With the improvement of people's life quality, the demand for pure water and soft water is higher and higher. Especially in some high hardness areas, soft water is needed for bathing, washing face, etc., and pure water is used for kitchen cleaning, drinking, etc.

[0003] Whole house water purifier and whole house soft water machine can meet people's whole house water demand. However, both products are directly connected to the user's water main pipe. When the product fails, it may cause the user to be completely unable to use water, or continuous water leakage accidents, etc. Therefore, the current whole house water purifier and whole house soft water machine are processed by setting a bypass valve on the product. When the product fails, the bypass valve is adjusted to cut off the water inlet of the product and connect the user's water pipe, so that the water does not enter the product while ensuring normal water use of the user.

[0004] At present, the existing bypass valve is provided with two adjusting ball valves. If adjustment is needed, both adjusting valves need to be adjusted, and the operation complexity is high. UTILITY MODEL CONTENTS

[0079] As Figures 1 to 5As shown, the embodiment provides a bypass valve 100 for water purifiers and water softeners, the bypass valve 100 comprising a valve seat 1 and a valve core 2, the valve seat 1 being provided with a containing cavity 11, a first water inlet 12, a second water inlet 13, a first water outlet 14 and a second water outlet 15, the first water inlet 12, the second water inlet 13, the first water outlet 14 and the second water outlet 15 being in communication with the containing cavity 11, the first water inlet 12 being in communication with the water purifier, the first water outlet 14 being in communication with the user end, the second water inlet 13 being in communication with the water source, the second water outlet 15 being in communication with the water softener, the valve core 2 being rotatably connected in the containing cavity 11 and used for switching the state of the valve seat 1; in the first state, the first water inlet 12 and the first water outlet 14 are in communication, and the second water inlet 13 and the second water outlet 15 are in communication; in the second state, the second water inlet 13 and the first water outlet 14 are in communication. Specifically, when in the first state, the first water inlet 12 is in communication with the first water outlet 14, so that the purified water treated by the water purifier can flow to the user end smoothly, meeting the daily drinking water needs of the user, and at the same time, the second water inlet 13 is in communication with the second water outlet 15, ensuring that the water source can continuously and stably flow into the water softener, providing necessary water source support for the normal operation of the water softener. When switched to the second state, the second water inlet 13 is in communication with the first water outlet 14, so that the water source originally directly flowing to the water softener can be guided to the user end, providing more water use options for the user. In some special cases, such as when the water purifier needs to be maintained or the water softener temporarily does not need to work, the bypass valve 100 can ensure that the water use needs of the user end are still met, avoiding the water use terminal caused by equipment failure or maintenance. In addition, when the valve core 2 is rotated to the first state, the communication of the water purifier and the water use end and the water source and the water softener can be realized at the same time. In other words, by adopting the above structure, only one operation is needed to realize the communication of the water purifier and the water use end and the water source and the water softener, thereby reducing the complexity of the operation. In addition, when the water softener needs to replace the resin, the switching between the first state and the second state can be realized by rotating the valve core 2, thereby ensuring that the water in the main water pipeline does not enter the water softener, so that only one valve core 2 needs to be rotated to realize the switching between the first state and the second state, having the characteristics of convenient operation.

[0104] The embodiment also provides a pure soft water machine, the pure soft water machine includes a bypass valve 100, the pure soft water machine includes a pure water machine and a soft water machine, the pure water machine is connected with the first water inlet 12, and the soft water machine is connected with the second water outlet 15.The above structure is used, the bypass valve 100 is applied to the pure soft water machine, when being in the first state, the first water inlet 12 is connected with the first water outlet 14, so that the pure water treated by the pure water machine can flow to the user end smoothly, meets the daily drinking water demand of user, and simultaneously, the second water inlet 13 is connected with the second water outlet 15, ensures that water source can continuously and stably flow into the soft water machine, provides necessary water source support for normal operation of the soft water machine.When switching to the second state, the second water inlet 13 is connected with the first water outlet 14, so that the water source originally directly flowing to the soft water machine can be guided to the user end, provides more water selection for user.In certain special circumstances, such as the pure water machine needs maintenance or the soft water machine temporarily does not need to work, the bypass valve 100 can ensure that the water demand of the user end is still satisfied, avoids the water terminal of equipment failure or maintenance.In addition, when the valve core 2 is rotated to the first state, the pure water machine and the water end and the water source and the soft water machine can be connected simultaneously.In other words, by using the above structure, the pure water machine and the water end and the water source and the soft water machine can be connected by one operation, thereby reducing the complexity of operation.In addition, when the soft water machine needs to replace resin, the first state and the second state can be switched by rotating the valve core 2, so that the water in the water main pipe can not enter the soft water machine, so that the first state and the second state can be switched by rotating one valve core 2, and the operation is convenient.

[0105] Although the specific embodiments of the present application are described above, those skilled in the art should understand that this is only an example, the protection scope of the present application is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present application, and these changes and modifications all fall within the protection scope of the present application.
