Description

Technical Field

[0002] At present, the temperature sensor at the outlet of electric water faucets plays an important role in automatically adjusting water temperature, preventing scalding accidents, saving energy and reducing consumption, and extending the life of appliances. With the continuous advancement of electric water faucets and the widespread application of intelligent control, their various functional configurations have been improved.

[0003] An electric water faucet in the prior art usually includes a bolted heating tube inside. Municipal water flows into the interior from the water inlet and is heated by the heating tube before being output from the water outlet at the other end. In addition, the water outlet is usually an open through-port setting. When the flow rate of the inlet water is large and the heating tube does not reach the expected temperature, the water flows directly from the water outlet, causing the temperature of the outlet water flow to fail to reach the expected effect. Or, even if the heating tube reaches the expected temperature, the outlet water flow rate is too fast, resulting in insufficient heating effect. Although the outlet water flow has achieved the heating effect, it does not match the actual set temperature, that is, the outlet water temperature does not match the set temperature.

[0012] Furthermore, the temperature-activated element includes a main body and a temperature-activated part arranged on the main body, wherein the temperature-activated part expands under the action of temperature increase and pushes out the water control valve, so that the water control valve moves away from the limited water outlet and releases the water flow gap, or the temperature-activated part returns to its original position and pulls the water control valve under the action of non-temperature increase, so that the water control valve abuts against the limited water outlet and maintains the water flow gap.

[0013] Furthermore, a first conical surface is provided at the end of the water inlet channel, and a second conical surface is provided on the water outlet side of the water control valve and is arranged opposite to the first conical surface, and the first conical surface is arranged at intervals from the second conical surface, and a water flow gap is defined between the first conical surface and the second conical surface.

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] It should be understood that although the terms upper, middle, lower, top, 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, and are not used to define any direction or order limitation.

[0045] like Figure 1-11 As shown, a water outlet faucet comprises:

[0046] The invention comprises a housing assembly 1, a water inlet cavity 2 defined in the housing assembly 1, and a water inlet channel 3 connected to the water inlet cavity 2, a heating module 4 is also arranged in the water inlet cavity 2, a water outlet channel 8 arranged opposite to the water inlet channel 3 is arranged in the housing assembly 1, a pressure difference switch 5 electrically connected to the heating module 4 is also arranged in the housing assembly 1, the water inlet channel 3 is connected to the pressure difference switch 5, and the pressure difference switch 5 is used to control the on and off of the heating module 4;

[0047] The differential pressure switch 5 is arranged at the lower end of the water inlet channel 3, and the water inlet channel 3 extends downward to form a water inlet detection channel 93.5, which is connected to the differential pressure switch 5, so that water flows into the water inlet detection channel 93.5 in the hot water mode, thereby acting on the differential pressure switch 5, so that the differential pressure switch 5 is turned on and the heating module 4 is turned on;

[0048] A water control assembly 6 is provided between the water inlet channel 3 and the water outlet channel 8. The water control assembly 6 comprises: a water control valve 6.1 provided in the water inlet channel 3, and a temperature-activated element 6.2 linked to the water control valve 6.1. The temperature-activated element 6.2 is located on the water outlet channel 8 and contracts or expands according to the temperature in the cavity and the temperature of the outlet water flow, thereby actuating the relative position of the water control valve in the water inlet channel 3.

[0049] Specifically, a water gap 7 for water flow to pass through is provided between the water control valve 6.1 and the water inlet channel 3. The water gap 7 is used for the water flow to pass through. The temperature-activated element 6.2 is configured to actuate the water control valve 6.1 under the action of temperature increase and release the water gap 7 between the water control valve 6.1 and the water inlet channel 3. At this time, the water control valve 6.1 moves and opens the opening of the water inlet channel 3, thereby improving the water outlet smoothness.

[0050] It should be pointed out that the above-mentioned release of the water gap 7 refers to the expansion of the gap between the water control valve 6.1 and the water inlet channel 3 to allow the inlet water flow to pass quickly.

[0051] Specifically, in the hot water mode, the water control component 6 is configured to pull the water control valve 6.1 in a non-heating state and maintain the water gap 7, that is, when the outlet water temperature or the temperature in the cavity does not reach the expected level, the temperature-activated element 6.2 pulls the water control valve 6.1 under the influence of relatively low temperature, so that the water control valve 6.1 is maintained at the position of the water gap 7 in the water inlet channel 3. One of its purposes is to ensure that in the hot water mode, the inlet water flow can be blocked by the water control valve 6.1 and fully act on the pressure difference switch 5 to ensure the start-up of the pressure difference switch 5 and the heating module 4. The second purpose is to monitor the outlet water temperature, that is, when the outlet water temperature does not reach the expected level, the water flow entering the water inlet chamber 2 is blocked. On the premise of ensuring that the heating module 4 is turned on, the outlet water flow rate of the water outlet channel 8 is reduced, so that the water flow in the water inlet chamber 2 is fully heated to reach the expected temperature, and the water inlet channel 3 is released after the outlet water flow reaches the expected temperature, thereby improving the water outlet smoothness.

[0052] Reference Figure 1 As shown, as a further embodiment of the housing assembly 1, the housing assembly 1 includes a main housing 1.1, and a water inlet end 10.1 cover 1.2 and a water outlet end cover 1.3 arranged at both ends of the main housing 1.1, wherein the water outlet faucet also includes a hand valve 10 arranged on the outside of the main housing 1.1, and a water inlet end 10.1 cover 1.2 arranged at the bottom of the main housing 1.1, the hand valve 10 is provided with a water inlet end 10.1, a hot water end 10.2 and a cold water end 10.3, and the water inlet end 10.1 cover 1.2 is connected to the main housing 1.1. 1 is provided with a water inlet pipe 11 corresponding to the water inlet end 10.1, and the main shell 1.1 is also provided with a hot water inlet end 1210.1 corresponding to the hot water end 10.2, and a cold water inlet end 1310.1 corresponding to the cold water end 10.3, and the water inlet end 10.1 on the hand valve 10 is normally connected with the water inlet pipe 11, and the water inlet pipe 11 on the main shell 1.1 is selectively connected with the hot water inlet end 1210.1 or the cold water inlet end 1310.1 by rotating the hand valve 10.

[0053] Continue to refer to Fig.11 Furthermore, the hot water inlet end 1210.1 is connected to the water inlet channel 3 and the water inlet detection channel 93.5, so that at the current position, the water flow acts on the pressure difference switch 5 and connects the electronic control component 15, so that the heating module 4 is energized and starts working, while the cold water inlet end 1310.1 is directly connected to the water inlet chamber 2, thereby avoiding the water control valve 6.1 and the water control component 6. At this time, there is no water flow in the water inlet detection channel 93.5, and the pressure difference switch 5 and the heating module 4 are not turned on, thereby realizing the selection of hot water and cold water modes of the faucet.

[0054] from Figure 6It can be seen that, as a further implementation method of the cooperation between the water control valve 6.1 and the water outlet channel 8, the water outlet channel 8 and the water control component 6 are arranged at the top of the water inlet channel 3, and the top of the water inlet channel 3 is provided with a limited water outlet 3.1 matching the contour of the water control valve 6.1, the water control valve 6.1 is restricted from detaching from the limited water outlet 3.1, and a water gap 7 is defined between the limited water outlet 3.1 and the contour of the water control valve 6.1.

[0055] Preferably, the water control valve 6.1 matches the contour of the water inlet channel 3, so that the water control valve 6.1 can slide in the water inlet channel 3 under the action of the temperature-activated element 6.2.

[0056] Specifically, a first conical surface 3.2 is provided at the end of the water inlet channel 3, and a second conical surface 6.11 is provided on the water outlet side of the water control valve 6.1 and is arranged opposite to the first conical surface 3.2, and the first conical surface 3.2 is arranged spaced from the second conical surface 6.11.

[0057] Reference Fig.10 As an example, the contours of the water inlet channel 3 and the water control valve 6.1 are both in an incomplete ring shape or a fan-shaped arrangement, with conical surfaces at both ends. Two cones 3.4 are arranged on the limit water outlet 3.1 at the top end of the water inlet channel 3, the first cone 3.2 is arranged on the two cones 3.4, and the second cone 6.11 is arranged at both ends of the water control valve 6.1. Under normal conditions, the water control valve 6.1 abuts against the limit water outlet 3.1, and the first cone 3.2 and the second cone 6.11 are arranged. A water gap 7 is defined between the conical surfaces 6.11, and under the effect of temperature increase, the temperature-activated element 6.2 expands and pushes the water control valve 6.1 downward away from the limited water outlet 3.1, thereby releasing the water gap 7 and increasing the water gap 7 between the water control valve 6.1 and the limited water outlet 3.1. After the hot water mode ends, the temperature-activated element 6.2 returns to its initial position due to the cooling effect, and at this time, the water control valve 6.1 is pulled and returns to the position abutting against the limited water outlet 3.1.

[0058] As a further implementation of the water control component 6, the water control component 6 also includes a water control mounting seat 6.3 fixed in the water outlet channel 8, and a floating seat 6.4 movably arranged on the water control mounting seat 6.3, the temperature-controlled element 6.2 is arranged on the floating seat 6.4, the floating seat 6.4 is transmission-connected to the water control valve 6.1, and an elastic member 6.5 is arranged between the axial position of the floating seat 6.4 and the water control mounting seat 6.3, wherein the floating seat 6.4 is penetrated through the water control mounting seat 6.3, the elastic member 6.5 can be selected as a spring, and the spring is limited in the circumferential direction between the floating seat 6.4 and the water control mounting seat 6.3.

Under the action of the elastic member 6.5, the upper end of the floating seat 6.4 abuts against the water control limit seat 6.7, and a plurality of bolt connection columns for fixing the water control mounting seat 6.3 are also provided on the peripheral side of the water control limit seat 6.7, so that the water control mounting seat 6.3 is fixed on the water outlet end cover 1.3.

[0060] Specifically, the temperature-activated element 6.2 includes a main body 6.21 and a temperature-activated part 6.22 arranged on the main body 6.21. The temperature-activated part 6.22 is used to respond to changes in the temperature of the water inlet chamber 2 and the water outlet. The temperature-activated part 6.22 expands under the action of temperature increase and overcomes the elastic member 6.5 to push out the water control valve 6.1, so that the water control valve 6.1 is away from the limited water outlet 3.1 and the water flow gap 7 is released, or the temperature-activated part 6.22 returns to its original position without the action of temperature increase, and pulls the water control valve 6.1 under the action of the elastic member 6.5, so that the water control valve 6.1 abuts against the limited water outlet 3.1 and maintains the water flow gap 7.

[0061] As an option, the warm moving part 6.22 can be a wax pack.

[0062] Preferably, the floating seat 6.4 is provided with a plurality of water grooves 6.41, which are connected to the water control limit seat 6.7, and the temperature-activated element 6.2 abuts against the water grooves 6.41. The water grooves 6.41 are used to increase the contact area between the temperature-activated element 6.2 and the outlet water flow, making the water control action more precise.

[0063] Specifically, the water control component 6 also includes a linkage rod 6.6, which extends from the water outlet end cover 1.3 side toward the water inlet channel 3. One end of the linkage rod 6.6 is fixedly connected to the water control valve 6.1, and the other end is transmission-connected to the temperature-activated element 6.2, wherein the other end of the linkage rod 6.6 is specifically fixedly connected to the floating seat 6.4, thereby forming a transmission with the temperature-activated element 6.2, and the temperature-activated element 6.2 is arranged near the end of the water outlet channel 8 to respond to the outlet water temperature.

[0064] like Figure 3 and Figure 6 and Fig. 9 As shown, specifically, a plurality of guide members 3.3 are provided at the end of the water inlet channel 3, the guide members 3.3 are located outside the water inlet channel 3 and inside the water inlet chamber 2, the guide members 3.3 extend toward the water outlet direction, the linkage rod 6.6 is passed through the guide members 3.3, and the guide members 3.3 extend toward the peripheral side, through this method, the movement stability of the linkage rod 6.6, the floating seat 6.4 and the water control valve 6.1 is effectively improved.

[0065] Reference Figure 5 and Figure 8 As shown, in other embodiments, the water outlet channel 8 includes a first water outlet 8.1 connected to the water inlet chamber 2, and a second water outlet 8.2 controlled by the water control component 6, the first water outlet 8.1 and the second water outlet 8.2 are both formed on the water outlet end cover 1.3, the floating seat 6.4 includes a normal temperature state closed on the second water outlet 8.2, and a hot water state separated from the second water outlet 8.2 under the action of temperature increase, the floating seat 6.4 keeps the second water outlet 8.2 closed through the elastic member 6.5 under the normal temperature state, and in the hot water state, the temperature-activated element 6.2 overcomes the elastic member 6.5 and actuates the floating seat 6.4 away from the second water outlet 8.2. Through the above improvements, during normal water outlet, water can be output through the first water outlet 8.1 to ensure the water outlet flow rate, and in the normal hot water mode, water can flow smoothly into the water inlet chamber 2, and water can flow smoothly out of the water outlet channel 8, and the water outlet is smoother.

[0066] In other embodiments, the water control valve 6.1 is positioned in the water inlet channel 3 above the hot water inlet end 1210.1 and adjacent to the hot water inlet end 1210.1, so that when the expected working state is reached, the water control valve 6.1 moves downward under the expansion action of the temperature-activated element 6.2 and releases the water gap 7. At the same time, the downwardly moving water control valve 6.1 compresses the opening size of the hot water inlet end 1210.1, thereby increasing the flow rate of water in the water inlet channel 3 and making the hot water flow more smoothly.

[0067] like Fig.11 As shown, in the above embodiment, the differential pressure switch 5 includes a diaphragm member 5.2, and a sliding member 5.1 formed on the diaphragm member 5.2, the opposite sides of the diaphragm member 5.2 define a detection chamber 5.4 and a balance chamber 5.3, the balance chamber 5.3 is connected to the water inlet chamber 2, and the detection chamber 5.4 is connected to the bottom of the water inlet channel 3, the sliding member 5.1 receives the electric control component 15, the electric control component 15 is electrically connected to the heating module 4, the electric control component 15 specifically includes a moving contact piece 15.1 and a stationary contact piece 15.2, wherein the moving contact piece 15.1 is docked with the sliding member 5.1, and in the heating mode, the detection chamber 5.4 detects the water inlet pressure, at which time the sliding member 5.1 moves downward and actuates the moving contact piece 15.1 to overlap with the stationary contact piece 15.2, at which time the heating module 4 is powered on, the specific function and structure of the differential pressure switch 5 have been fully disclosed in the prior art, and will not be elaborated on here.
