[0007] Preferably, in the above double water filter, a liquid inlet channel is formed on one side of the valve body, and the liquid inlet channel communicates with the cavity inside the plug.

[0008] Preferably, in the above double water filter, upper and lower orifices are formed on the plug and are arranged corresponding to each other.

[0009] When the left filter cartridge works, the upper orifice communicates with the left channel; when the right filter cartridge works, the lower orifice communicates with the right channel.

[0010] Preferably, in the above double water filter, a lifting handle is arranged at the top of the valve body.

[0011] Preferably, in the above double water filter, drain bolts are respectively arranged on the left filter cartridge and the right filter cartridge.

[0012] Compared with the prior art, the utility model realizes the conversion of the plug core by rotating the handle, which is simple to operate, safe and reliable, effectively solving the defects of the traditional single-barrel filter in this regard. When the filter element is blocked, the filter element can be cleaned or replaced without shutting down the machine, saving time and ensuring the normal continuous operation of the main machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings described below are only some embodiments recorded in the present application. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0015] Figure 2 The figure shows a top view of the double-filter water filter in the embodiment of the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will describe in detail the technical solutions in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts belong to the scope of protection of the utility model.

[0017] Combined with Figure 1-2 As shown, the double-filter water filter 100 includes a valve body 101. A plug cock 102 is formed inside the valve body 101. A bushing 103 is sleeved outside the plug cock 102. A driving handle 104 is arranged at the top of the plug cock 102. Left and right channels 105 and 106 are respectively formed at both ends of the plug cock 102. The left channel 105 communicates with the left filter cartridge 107, and the right channel 106 communicates with the right filter cartridge 108. After the driving handle 104 rotates, the cavity inside the plug cock 102 communicates with the left channel 105 or the right channel 106.

[0018] A liquid inlet channel 109 is formed on one side of the valve body 101, and the liquid inlet channel 109 communicates with the cavity inside the plug cock 102. Upper and lower cavity openings 110 and 111 are formed on the plug cock 102 and are arranged in an up-and-down corresponding manner. When the left filter cartridge 107 works, the upper cavity opening 110 communicates with the left channel 105; when the right filter cartridge 108 works, the lower cavity opening 111 communicates with the right channel 106. A lifting handle 112 is arranged at the top of the valve body 101. Drain bolts 113 are respectively arranged on the left filter cartridge 107 and the right filter cartridge 108.

[0019] In this technical solution, the defects of traditional single-barrel filters in this regard are effectively solved. When the filter element is blocked, the filter element can be cleaned or replaced without shutting down the machine, which not only saves time but also ensures the normal continuous operation of the main machine.

[0020] The characteristics of the dual water filter are that when one filter element needs to be replaced due to blockage, there is no need to stop the working main machine. Just gently turn the handle, and the filtration work can be transferred to the other filter, and then replace the blocked filter element. At the same time, it has many advantages such as novel and reasonable structure, good sealing performance, strong fluidity, and simple operation. It is a multi-purpose filtering device with a wide range of applications and strong applicability. In addition, the probability of side leakage of the filter cartridge is small, the filtration accuracy can be accurately guaranteed, the filter cartridge can be quickly replaced, and there is basically no material consumption during filtration, which reduces the operation cost.

[0021] During specific use, when one of the filter cartridges is blocked, just turn the drive handle to the other side to connect to the other filter cartridge.

[0022] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0023] The above are only specific implementation manners of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
