Technical Field

[0001] The utility model relates to the technical field of water outlet devices, and particularly relates to a water outlet faucet convenient for assembly. Background Art

[0002] At present, the temperature sensor at the water outlet end of an electric water faucet plays an important role in aspects such as automatically adjusting the water temperature, preventing scalding accidents, energy conservation and consumption reduction, and extending the service life of appliances. With the continuous progress of electric water faucets and the wide application of intelligent control, all its functional configurations have been improved. Therefore, the installation and maintenance of electric water faucets are a major improvement direction.

[0003] In an existing electric water faucet, since the heating tube is usually placed inside the faucet housing, and there are connection relationships between the housing components inside the faucet housing and the components on the housing components and the heating tube, the disassembly and replacement of the heating tube involve the positions of other housing components and components. For example, the heating tube is welded and fixed to other sensing elements. This arrangement of the heating tube increases the difficulty of maintaining and installing the heating tube. At the same time, in the market of electric water faucets, the heating tube is usually used as a universal fitting to adapt to faucet housings of different specifications, which also results in low adaptability of the heating tube to different faucet housings. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a water outlet faucet convenient for assembly.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A water outlet faucet convenient for assembly, comprising:

[0011] Further, the heating module includes at least one heating unit and a connecting seat body integrally arranged at the end of the heating unit. The connecting seat body is provided with a conductive sheet, and the conductive sheet and at least part of the connecting seat body are arranged in the electrical connection area.

[0012] Further, the housing assembly includes a main housing and an end cover member arranged at the end of the main housing. A slot seat for placing the connecting seat body is provided on the main housing and / or the end cover member.

[0016] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0017] By providing an exposed electrical connection area on the housing assembly, the electrical connection part of the heating module and the electrical connection position of the first electrical control component electrically connected to the heating module are also arranged in the electrical connection area.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0043] It should be understood that although the terms upper, middle, lower, top, one end, etc. appear in this text to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for easy understanding, rather than for defining any directional or sequential limitations.

[0044] As Figures 1 - 12 described, a water outlet faucet convenient for assembly includes:

[0045] A housing assembly 1, a heating module 2 disposed inside the housing assembly 1, and a wire pressing plate 3 detachably disposed on the housing assembly 1. The wire pressing plate 3 defines an electrical connection area 4 on the housing assembly 1. At least one first electrical control component 5 electrically connected to the heating module 2 is provided inside the housing assembly 1. The electrical connection parts of the heating module 2 and the electrical connection parts of the first electrical control component 5 and the heating module 2 are arranged in the electrical connection area 4 along adjacent heights. Thus, the electrical connection parts of the electric water faucet are integrated in the electrical connection area 4. By removing the wire pressing plate 3, the electrical connection area 4 on the housing assembly 1 can be exposed (as shown by the dotted line in Figure 2 ), and the electrical connection parts therein can be repaired.

[0046] Specifically, an inlet part 6 for the power cord to access is provided on the housing assembly 1. The inlet part 6 is located in the electrical connection area 4 and is covered by the wire pressing plate 3. The inlet part 6 is specifically presented as a notch matching the contour of the power cord. By this means, during the assembly process, after the housing assembly 1 and the internal heating module 2 are assembled in advance, when the wire pressing plate 3 is detached, the electrical connection parts in the electrical connection area 4 can be connected.

[0047] As a further explanation of the first electrical control component 5, the first electrical control component 5 refers to any one or more of a differential pressure switch 5.1 or a thyristor 5.2, and the differential pressure switch 5.1 and the thyristor 5.2 are electrically connected to the heating module 2.

[0048] As Figure 4 shown, as a further implementation manner of the housing assembly 1, the housing assembly 1 includes a main housing 1.1 and an end cover member disposed at the end of the main housing 1.1. The electrical connection area 4 is formed between the end cover member and the main housing 1.1, and the wire pressing plate 3 is closed between the main housing 1.1 and the end cover member. The end cover member is composed of a water inlet end cover 1.2 and a water outlet end cover 1.3 located at both axial ends of the main housing 1.1. The water inlet end cover 1.2 and the water outlet end cover 1.3 are axially closed on the main housing 1.1, and the end cover member is preferably fixed to the upper and lower ends of the main housing 1.1 by a bolt connection method. The screwing direction of the bolt is consistent with the direction in which the end cover member is fitted on the main housing 1.1. With the cooperation of the end cover member and the main housing 1.1, the electrical connection area 4 is formed, thus facilitating the rapid assembly of the housing assembly 1.

[0049] As Figure 11As shown, a special-shaped rubber ring 11 is provided between the water outlet end cover 1.3 and the main housing 1.1. The special-shaped rubber ring 11 specifically refers to a non-circular non-standard rubber ring, which has a plurality of inwardly bent arc segments 11.1. In this way, the special-shaped rubber ring 11 serves as a sealing part, effectively improving its position stability between the water outlet end cover 1.3 and the main housing 1.1. At the same time, the sealing area is increased, making the sealing effect more reliable.

[0050] Further referring to Figure 11 、 Figure 12 and Figure 8 Moreover, on the water outlet end cover 1.3, a first mating contour 12 that matches the inner contour of the special-shaped rubber ring 11 and a first mating groove 14 located outside the first mating contour 12 are provided. On the top of the main housing 1.1, a second mating contour 13 that matches the outer contour of the special-shaped rubber ring 11 and a second mating groove 15 located inside the second mating contour 13 are provided. The first mating groove 14 and the second mating groove 15 match the end face contour of the special-shaped rubber ring 11, so that both the inner and outer sides of the special-shaped rubber ring 11 are abutted within the first mating contour 12 and the second mating contour 13, and the first mating groove 14 and the second mating groove 15 axially abut the special-shaped rubber ring 11, thereby further ensuring the position reliability of the special-shaped rubber ring 11 and ensuring the sealing performance.

[0051] Preferably, the water outlet end cover 1.3 is arranged on the circumferential side of the special-shaped rubber ring corresponding to the bolt connection position between the main housing 1.1.

[0052] Specifically, the end cover member includes an inlet end cover 1.2 and a water outlet end cover 1.3 arranged at the upper and lower ends of the main housing 1.1. The inlet end cover 1.2 and the bottom of the main housing 1.1 together define an electrical connection area 4. As an example, the inlet end cover 1.2 is arranged at the lower end of the main housing 1.1. A first opening 1.11 is provided at the lower end of the main housing 1.1, and a second opening 1.21 is provided on the inlet end cover 1.2. The first opening 1.11 and the second opening 1.21 are connected and define the electrical connection area 4. The wire pressing plate 3 is specifically closed on the first opening 1.11 and the second opening 1.21. Among them, the incoming line part 6 is located on the second opening 1.21, the thyristor 5.2 is fixed on the inlet end cover 1.2, and the electrical connection part of the heating module 2 extends at the first opening 1.11.

[0053] Preferably, the wire pressing plate 3 is fixed on the housing assembly 1 by bolts or buckles.

[0054] Such as Figure 2 and Figure 3As shown, as a preference, the differential pressure switch 5.1 is fixed to the bottom of the main housing 1.1 and is located on the back of the heating module 2. The electrical connection portion between the differential pressure switch 5.1 and the heating module 2 is arranged at the bottom of the heating module 2 and is located above the thyristor 5.2. The line inlet portion 6 is located below the thyristor 5.2, thereby distinguishing different electrical connection portions in the electrical connection area 4 in the height direction. The electrical connection portions of the first electronically controlled component 5 are all arranged between the water inlet end cover 1.2 and the main housing 1.1 to facilitate maintenance and assembly operations.

[0055] Furthermore, the heating module 2 has multiple electrical connection parts, which are arranged horizontally in the electrical connection area 4, so that the electrical connection parts of the heating module 2 are clearly and intuitively exposed in the electrical connection area 4, and do not interfere with other first electrical control components 5.

[0056] like Figure 8 and Figure 9 As shown, as a further improvement to the end cover component, the electrical connection area 4 also includes a vertical space 4.1 separated between the water inlet end cover 1.2 and the main shell 1.1. The vertical space 4.1 provides a placement space for the first electrical control component 5 and the heating module 2, as well as the electrical connection parts thereon, and other electrical control components and their electrical connection parts at the bottom of the water outlet faucet that are away from the open electrical connection area 4 can be connected to the electrical connection area 4 through the vertical space 4.1.

[0057] like Figures 6 to 7 As shown, as a further embodiment of the heating module 2, the heating module 2 includes at least one heating unit 2.1, and a connecting seat body 2.2 integrally arranged at the end of the heating unit 2.1, a conductive sheet 2.3 is provided on the connecting seat body 2.2, and the conductive sheet 2.3 and at least part of the connecting seat body 2.2 are arranged in the electrical connection area 4, wherein the conductive sheet 2.3 is arranged as an electrical connection component to form an electrical connection with other electrical control components in the water faucet.

[0058] Specifically, the connecting seat body 2.2 is integrally formed with the heating tube body by injection molding, and the heating module 2 also includes a conductive plate, which is connected to the ends of multiple heating units 2.1, and a conductive insert 2.4 connected to the conductive plate is embedded in the connecting seat body 2.2. The conductive sheet 2.3 located outside the connecting seat body 2.2 is connected to the conductive insert 2.4, thereby ensuring the stability of the electrical connection between the conductive sheet 2.3 and the heating module 2.

[0059] As a further embodiment of the conductive sheet 2.3 and the conductive insert 2.4, a threaded hole is provided in the conductive insert 2.4, and holes for bolts to pass through are provided on the conductive sheet 2.3. The conductive sheet 2.3 is fixed to the conductive insert 2.4 by bolts.

[0060] Further referencesFigure 8 and Figure 9 For the housing assembly 1, it includes a main housing 1.1 and an end cover member provided at the end of the main housing 1.1. A slot seat 1.4 for inserting the connection seat body 2.2 is provided on the main housing 1.1 and / or the end cover member. Among them, the connection seat body 2.2 preferably has a regular contour and is inserted into the slot seat 1.4 in a vertical plugging manner. In this way, the installation of the heating module 2 is more efficient. At the same time, for different specifications of the housing assembly 1, only by setting the slot seat 1.4 inside it can the installation of the heating module 2 be realized, improving the adaptability of the heating module 2.

[0061] As an example, the slot seat 1.4 is specifically provided on the water inlet end cover 1.2 and the top of the main housing 1.1. Thus, after the main housing 1.1 and the water inlet end cover 1.2 are assembled, the assembly of the heating module 2 can be completed.

[0062] Preferably, the heating unit 2.1 is arranged in a vertical tubular shape to facilitate the layout of the spatial position of the heating module 2 in the housing assembly 1, thereby improving the adaptability of the heating module 2 to different housings.

[0063] As Figure 3 、 Figure 8 and Figure 9 As shown, as a further implementation manner of the differential pressure switch 5.1, the differential pressure switch 5.1 is connected to the water inlet waterway of the water outlet faucet. The differential pressure switch 5.1 is provided with a static contact piece 5.11 and a moving contact piece 5.12. The moving contact piece 5.12 is arranged on the movable part of the differential pressure switch 5.1. The moving contact piece �.12 is used to receive the inlet water pressure and engage with the static contact piece 5.11. The static contact piece 5.11 and the moving contact piece 5.12 are connected to the electrical connection parts of the heating module 2.

[0064] As Figure 10 shown, specifically, the differential pressure switch 5.1 is arranged on the back of the connection seat body 2.2 corresponding to the electrical connection area 4. The static contact piece 5.11 is arranged at the bottom of the differential pressure switch 5.1. The bottom of the heating module 2 is provided with a second connection position corresponding to the static contact piece 5.11 and a first connection position corresponding to the moving contact piece 5.12. The conductive sheets 2.3 at the first connection position and the second connection position are bent in an L shape at the bottom of the connection seat body 2.2 and extend backward to the bottom of the differential pressure switch 5.1, and then remain in an electrically connected state with the differential pressure switch 5.1.

[0065] As a further embodiment of the cooperation between the pressure differential switch 5.1 and the heating module 2, a first leg 5.13 and a second leg 5.14 are extended from the pressure differential switch 5.1. The movable contact piece 5.12 is placed in the first leg 5.13, and the static contact piece 5.11 is placed in the second leg 5.14. A first docking groove 2.6 is provided at the bottom of the connecting base 2.2 corresponding to the first connecting position 2.7. The first leg 5.13 is partially placed in the first docking groove 2.6. The second leg 5.14 is provided with a second docking groove 5.15 for receiving the conductive piece 2.3. Therefore, the static contact piece 5.11 and the movable contact piece 5.12 are both electrically connected within the first leg 5.13 and the second leg 5.14, thereby ensuring the stability of the cooperation between the pressure differential switch 5.1 and the heating module 2.

[0066] Optionally, the first leg 5.13, the conductive sheet 2.3 at the first connection position 2.7 and the movable contact sheet 5.12 are all provided with docking holes, and conductive pins are provided in the docking holes to form an electrical connection between the heating module 2 and the movable contact sheet 5.12 of the pressure differential switch 5.1.

[0067] Of course, a conductive insert 2.4 may also be embedded in the first leg 5.13 and the second leg 5.14 to connect the conductive components thereon.

[0068] Furthermore, the heating module 2 and the pressure differential switch 5.1 are electrically connected via the conductive sheet 2.3, so as to simplify the connection relationship between the heating module 2 and the pressure differential switch 5.1.

[0069] Among them, the pressure differential switch 5.1 uses a piston to bear the water pressure of the water inlet water channel, and the lower end of the piston is connected to the moving contact piece 5.12. Therefore, in the hot water mode, the moving contact piece 5.12 and the static contact piece 5.11 are driven to conduct through the water inlet pressure. At this time, the heating module 2 is turned on and energized. The pressure differential switch 5.1 in the water faucet has been fully applied and disclosed in the existing technology and will not be elaborated on here.

The housing assembly 1 is also provided with a temperature control installation groove 1.7 for positioning and embedding the temperature control switch 7.1. The first installation cavity 1.5 communicates with the water outlet end cover 1.3 upward and communicates with the water inlet end cover 1.2 downward. The heating module 2 is located in the water outlet end cover 1.3 and is provided with a neutral wire connection part 2.5. The temperature control switch 7.1 is connected to the heating module 2 through the neutral wire connection part 2.5.

[0075] Specifically, the water outlet end cover 1.3 is provided with a third opening 1.31. The neutral wire connection part 2.5 of the heating component is exposed in the third opening 1.31. The third opening 1.31 is located in the upper part of the first installation cavity 1.5 and communicates with the first installation cavity 1.5. The third opening 1.31 is closed by the first protective shell 8. And, a reset button 7.11 protrudes on the temperature control switch 7.1. The reset button 7.11 penetrates outside the first protective shell 8, so as to perform a reset operation on the temperature control switch 7.1 from the outside. Through the above improvement, when installing, disassembling and overhauling the temperature control switch 7.1, only need to remove the first protective shell 8, then the temperature control switch 7.1 and the neutral wire connection part 2.5 on the upper part of the heating component can be exposed for easy operation.

[0076] Preferably, the first protective shell 8 can be connected to the main housing 1.1 by means of bolt fixation, and the bolt also serves as the fixing means for the temperature control switch 7.1. Of course, the first protective shell 8 can also be set in a snap-fit manner, and an independent bolt fixing connection is arranged inside the temperature control switch.

[0077] Furthermore, the heating module 2 extends along the height direction of the water outlet faucet within the water inlet end cover 1.2 and the water outlet end cover 1.3.

[0078] As Figure 5As shown, as an implementation of the electronic control board 7.2, the second electronic control component 7 is set as the electronic control board 7.2. A second installation cavity 1.6 is formed on the housing assembly 1. A second protective shell 9 is detachably provided outside the second installation cavity 1.6.

The temperature sensor 10 is inserted into the water outlet end cover 1.3 from the outside, and the temperature sensor 10 is located in the water outlet channel inside the water outlet end cover 1.3. The second protective shell 9 is closed at the back of the temperature sensor 10, and the temperature sensor 10 is connected to the electronic control board 7.2 through a wire. The wire is arranged in the wiring channel defined between the second protective shell 9 and the second installation cavity 1.6. Through the above improvement, the electronic control board 7.2 and the temperature sensor 10 can be exposed by disassembling the second protective shell 9, so as to facilitate the later maintenance and repair of the water outlet faucet, and the electronic control board 7.2 and the temperature sensor 10 can be installed after the housing assembly 1 is assembled.

Since there is no need to consider the spatial position of the pressure plate 3 and the electrical connection area 4, the opening sizes of the fourth open end 1.12 and the fifth open end 1.22 can be designed to the greatest extent to further improve the convenience of overhauling and assembling the electronic control board 7.2.

[0082] In the present utility model, both the first installation cavity 1.5 and the second installation cavity 1.6 are located on the surface layer of the housing assembly 1, and are respectively closed and fixed by the first protective shell 8 and the second protective shell 9. Moreover, the first electric control component 5 and the second electric control component 7 inside them can be exposed by disassembling the first protective shell 8 and the second protective shell 9.
