[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than to define any directional or sequential limitations.

[0039] As Figures 1-10 shown, a heating module includes:

[0040] A plurality of heating tube units 1, a connecting seat body 2 integrally formed at the end of the heating tube unit 1, an internal electrical connection component 3 embedded in the connecting seat body 2, and an external electrical connection component 4 arranged outside the connecting seat body 2. The heating tube units 1 are linearly arranged on the connecting seat body 2, and the heating tube units 1 are electrically connected through the internal electrical connection component 3. The external electrical connection component 4 cooperates with the internal electrical connection component 3 and forms an electrical connection with an external power supply or an electrical control component.

[0041] By using the heating module of the present utility model, different numbers of heating tube units 1 can be set according to the actual heating power requirements. Of course, in order to cope with the space occupation of the heating module inside devices with different contours, the heating tube units 1 can also be arranged in a surrounding manner in sequence, or the arrangement mode of different heating tube units 1 can be set according to the actual space contour requirements.

[0042] Preferably, the connecting seat body 2 is an injection molded part, and is injection molded in a mold together with a plurality of arranged heating tube units 1, so as to ensure the fixed connection between the connecting seat body 2 and the heating tube units 1, and the internal electrical connection component 3 is formed in the connecting seat body 2 together, thereby realizing the integration and modularization of the heating module.

[0043] As Figures 1 to 3 shown, as a further explanation of the internal electrical connection component 3 and the external electrical connection component 4, by integrally forming the internal electrical connection component 3 in the connecting seat body 2 during the molding process, the position stability of the internal electrical connection component 3 connected to the heating tube unit 1 is ensured. At the same time, the internal electrical connection component 3 forms an electrical connection part 3.4 on the surface of the connecting seat body 2. The external electrical connection component 4 is preferably a conductive sheet, so as to directly form a circuit connection with the electrical connection part 3.4 exposed on the surface of the connecting seat body 2, realizing the rapid assembly of the heating module.

[0044] Further referring to Figure 2 andFigure 3 As a further implementation of the internal electrical connection component 3, the internal electrical connection component 3 includes a lead bar 3.1 and a conductive insert 3.2 embedded in the connection seat body 2. The lead bar 3.1 is correspondingly arranged with the heating tube unit 1. The conductive insert 3.2 is electrically connected to the lead bar 3.1 and forms an electrical connection part 3.4 on the surface of the connection seat body 2.

[0045] Among them, the lead bar 3.1 extends in the height direction of the connection seat body 2 and extends into the interior of the heating tube unit 1. The lead bar 3.1 at least extends outside the connection seat body 2. While ensuring the cooperation reliability between the lead bar 3.1 and the heating tube unit 1, the connection position between the lead bar 3.1 and the heating tube unit 1 is set above the connection seat body 2, that is, spaced from the connection seat body 2, thereby effectively preventing the temperature in the connection seat body 2 from being too high and reducing potential safety hazards.

[0046] In addition, the lead bar 3.1 also increases the structural strength of the connection seat body 2 to a certain extent. The conductive insert 3.2 is arranged within the projection range of the lead bar 3.1 on the connection seat body 2, thereby ensuring the mutual connection between the lead bar 3.1 and the conductive insert 3.2.

[0047] Specifically, the internal electrical connection component further includes a conductive connection row 3.3 embedded in the connection seat body 2. The conductive connection row 3.3 is arranged according to the arrangement direction of the heating tube unit 1 and connects the lead bars 3.1 on each heating tube unit 1, thereby realizing reliable connection between adjacent heating tube units 1.

[0048] Further referring to Figure 1 and Figure 10 As a further implementation of the external connection component, a plurality of embedding grooves 2.1 are provided on the connection seat body 2. The electrical connection part 3.4 of the internal electrical connection component 3 is exposed in the embedding grooves 2.1.

The conductive sheet unit 4.1 is electrically connected to the heating tube unit 1 through the internal electrical connection component 3, and the conductive sheet unit 4.1 is lapped with the electrical connection part 3.4 in the embedding grooves 2.1.

[0049] As a further implementation of the electrical connection part 3.4, a threaded hole is provided in the conductive insert 3.2, and a hole for a bolt to pass through is provided on the conductive sheet unit 4.1. The conductive sheet unit 4.1 is fixed on the conductive insert 3.2 through a bolt.

Specifically, the electrical connection part 3.4 of the conductive insert 3.2 is located within the limiting part 2.11, and the guiding part 2.12 forms an open mouth at the bottom of the connecting seat body 2 to guide the lead-out of the conductive sheet unit 4.1. The profiles of the limiting part 2.11 and the guiding part 2.12 are different. The limiting part 2.11 is used to snap the conductive sheet unit 4.1 therein to improve the reliability of the conductive sheet unit 4.1 on the connecting seat body 2.

[0051] As an example, the limiting part 2.11 can be selected as circular, and the guiding part 2.12 can be selected as a sheet shape consistent with the extending direction of the main body of the conductive sheet unit 4.1.

[0052] Preferably, the slot 2.1 and the conductive sheet unit 4.1 are located on the same side of the connecting seat body 2 to facilitate the electrical control connection and maintenance operation of the heating module. The conductive sheet unit 4.1 can be bent according to the relative position of the electrical control component and the heating module, making the electrical connection of the heating module convenient and controllable.

[0053] From Figure 2 As can be seen, in some other embodiments, a sealing assembly is further provided on the heating module.

[0056] Specifically, a second annular groove 2.2 is provided outside the connecting seat body 2, and a second sealing ring 2.3 is provided on the second annular groove 2.2. At least part of the second sealing ring 2.3 extends outside the second annular groove 2.2.

[0057] Specifically, a conductive bending part 5 is provided at the bottom of the connecting seat body 2 on the inner electrical connection assembly 3 and / or the outer electrical connection assembly 4. The outer electrical connection assembly 4 has an electrical connection position exposed on the front side or the rear side of the connecting seat body 2.

[0058] Optionally, the conductive bending part 5 can be a bend extending from the conductive connection row 3.3 or a bend extending from the conductive sheet unit 4.1. The conductive bending part 5 is preferably a horizontal bend.

[0060] Among them, the heating module is composed of a straight tubular heating tube unit 1 and a connecting seat body 2 formed at the end of the heating tube unit 1, so that the whole heating module has a regular shape, which is beneficial to the housing design and internal space planning of the water outlet faucet.

[0061] Specifically, at least one installation cavity is provided on the surface side of the main housing 6, and a cover body assembly is detachably provided on the main housing 6. The cover body assembly is closed on the installation cavity. An electric control component is provided in the installation cavity, and the external electric connection component 4 is exposed on the same side in the installation cavity.

The connecting seat body 2 at the bottom of the heating module and the external electric connection component 4 thereon are both exposed in the electric connection area 7. Moreover, the electric connection positions of the electric control components are exposed in the electric connection area 7, and an incoming line part 9 for accessing an external power cord is also provided in the electric connection area 7. In this way, by removing the wire pressing plate 8, the electric connection area 7 can be exposed, so as to overhaul and assemble the electric connection of the heating module.

[0063] As Figure 5 and Figure 9 shown, by way of example, the electric control component refers to a differential pressure switch 10 on one side of the heating module. A static contact piece 10.2 and a moving contact piece 10.1 for electrically connecting and cooperating with the heating module are provided at the bottom of the differential pressure switch 10. The static contact piece 10.2 of the differential pressure switch 10 is joined to the moving contact piece 10.1 and the external electric connection component 4 and / or the internal electric connection component 3 of the heating module.

[0064] As Figures 6 to 8 shown, in some other embodiments, the installation cavity further includes a first installation cavity 11 extending on the main housing 6. The first installation cavity 11 is provided on the surface side of the main housing 6 and is on the same side as the electric connection area 7.

The temperature control switch 12 contacts the heating module through the first installation cavity 11, and the first installation cavity 11 communicates with the electric connection area 7. The cover body assembly further includes a first protective shell 13 closed on the first installation cavity 11. In this way, the electric control components and the overhaul positions of the water outlet faucet can be exposed by removing the cover body assembly, which is convenient for assembly and maintenance, and further simplifies the internal space design of the main housing 6.

[0065] Optionally, the end cover member further includes a water outlet end cover 6.2 provided at the top of the main housing 6. The heating module also extends on the water outlet end cover 6.2. Specifically, a groove seat 6.3 is provided in the water outlet end cover 6.2, and the connecting seat body 2 at the upper end of the heating module is placed in the groove seat 6.3. The first installation cavity 11 also extends on the water outlet end cover 6.2, and an electrical connection part 3.4 at the upper end of the connecting seat body 2 is exposed on the water outlet end cover 6.2. The electrical connection part 3.4 can be used for electrical connection with the above-mentioned temperature control switch 12, or for forming an electrical connection with other electrical control components in the first installation cavity 11. This is all due to the vertically connected electrical connection area 7 and the first installation cavity 11, as well as the electrical connection part 3.4 on the heating module corresponding to the same side of the installation cavity.
