Specifically, the trigger 41 can determine whether or not water flows in the clean water chamber 35. When water flows, the trigger part 41 triggers the sensing part 42, the purified water entering the heating cavity 36 is heated, and when no water flows in the purified water cavity 35, the trigger part 41 releases the triggering of the sensing part 42, and the heating unit 3 stops heating.

It should be noted that the control switch 4 may be an inductive switch, and the triggering portion 41 may be a contact switch, that is, the triggering portion 41 may trigger the inductive portion 42 when directly contacting the water flow, or the triggering portion 41 may judge whether the water flow flows in the water purifying chamber 35 according to vibration or pressure difference, without directly contacting the water flow.

As a preferred example of this embodiment, in a structure in which the upper bracket 33 includes a first mounting portion 331, a second mounting portion 332 located below the first mounting portion 331, and a connecting portion 333 connecting the first mounting portion 331 and the second mounting portion 332, as shown in fig. 3 and 5, a mounting groove 3311 for mounting the control switch 4 is formed by recessing a top portion of the first mounting portion 331 downward, and the first mounting portion 331 is provided with a second flow guide passage 3312 communicating with the first flow guide passage 3331 and extending toward the trigger portion 41.

In this embodiment, the contact-type flow control switch 4 is selectively adopted, and the control switch 4 is disposed on the upper bracket 33, so that purified water flows out from the water outlet 3321 and then contacts the triggering portion 41 through the second diversion channel 3312, the triggering portion 41 is made of a flexible material, and deforms under the action of water flow and instantly triggers the sensing portion 42, so that water entering the heating cavity 36 can obtain a longer heating time before being discharged, that is, a greater temperature rise can be obtained, and the whole water flow path can be further shortened. Further, the extension of the water purifier in the longitudinal direction can be reduced by utilizing the accommodation space in the upper bracket 33.

Preferably, as shown in fig. 1, 3 and 11, the top of the housing 22 is provided with a top opening 222, and the filter unit 2 further includes an upper cover plate 27 for opening or closing the top opening 222, so that the control switch 4 can be detached from the upper bracket 33 through the top opening 222 of the housing 22, and when the control switch 4 fails, the control switch 4 can be repaired or replaced without detaching the heating unit 3 or the filter unit 2.

As a preferred embodiment of the present application, as shown in fig. 1, 8 and 9, all of the aforementioned embodiments and examples of the present application may further include a water channel plate 25 located in the housing 22 and detachably disposed below the purified water chamber 35, wherein the water channel plate 25 is integrated with the raw water inlet 251, the purified water outlet 252, a raw water inlet 253 communicating with the raw water inlet 251 and the water inlet 341, respectively, and a purified water outlet 254 communicating with the heating chamber 36 and the purified water outlet 252, respectively, the raw water inlet 251 extends from the housing 22 to communicate with the raw water inlet 11, and the purified water outlet 252 communicates with the outside.

The raw water inlet 251, the purified water outlet 252, the raw water inlet channel 253 and the purified water outlet channel 254 are integrated through the water channel plate 25, that is, all interfaces including those for feeding raw water, discharging raw water to the purified water cavity 35 and discharging hot water are integrated through one water channel plate 25, so that the integration of functions is realized, and the modularized assembly and disassembly of the functional units such as the filtering unit 2 and the heating unit 3 in the water purifier are facilitated.

And, water route switching unit 1, filter unit 2, the intercommunication between the most water ports of heating unit 3 all can be gone on water route board 25, through independent pipeline intercommunication between each mouth of a river has been avoided, the pipeline structure has been simplified, it produces mutual interference and dodges each other to have reduced in the installation between pipeline and each functional component (heating unit 3, filter unit 2), help the rational arrangement of pipeline, thereby help promoting leading water purifier inner structure's overall arrangement rationality and compactness, filter unit 2 has also been made things convenient for simultaneously, the dismouting of each component of heating unit 3.

Preferably, as shown in fig. 1 and 3, the filter unit 2 further includes a bubbler 28 disposed at the clean water outlet 252 of the water passage plate 25, so as to achieve a bubbling effect of the outlet water through a dense mesh of the bubbler 28.

Where not mentioned in this application, can be accomplished using or referencing existing technology.

All the embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from other embodiments.

The above description is only an example of the present application and is not intended to limit the present application. Various modifications and changes may occur to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
