[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, a further detailed description of this utility model will be provided below in conjunction with the accompanying drawings. It is hereby declared that any use of terms such as "up," "down," "left," "right," "front," "back," "inner," and "outer" in this document is based solely on the accompanying drawings and is not intended to specifically limit the scope of this utility model.

[0033] The integrated electric water faucet of this invention can reduce the number of parts during installation, reduce assembly errors and connection problems, and lower the risk of leakage.

[0034] In embodiments of this utility model, such as Figures 1 to 8 As shown, the integrated electric water faucet includes a heating body 1, a pump assembly 2, and an integrated component 3. The heating body 1 has a heating tube 11 inside and a water inlet 12. The pump assembly 2 is located at the water inlet 12. The integrated component 3 is positioned between the pump assembly 2 and the heating tube 11. The side of the integrated component 3 facing the pump assembly 2 is detachably connected to the pump assembly 2, and the side of the integrated component 3 facing the water inlet 12 is detachably connected to the heating body 1. The integrated component 3 has a connecting water channel 31, through which the outlet of the pump assembly 2 and the inlet of the heating tube 11 are connected.

[0035] According to this embodiment, the integrated electric water faucet detachably connects the side of the integrated component 3 facing the pump assembly 2 to the pump assembly 2, and detachably connects the side of the integrated component 3 facing the water inlet 12 of the heating pipe to the heating body 1. This integrates the pump assembly 2 and the housing into a single structure, reducing the number of parts during installation, simplifying the assembly process, and minimizing assembly errors and connection problems. Simultaneously, the connecting water channel 31 of the integrated component 3 connects the outlet of the pump assembly 2 and the inlet of the heating pipe 11, reducing the piping connection between the pump assembly 2 and the heating pipe 11, further lowering the risk of leakage.

[0036] It should be noted that, in order to facilitate the instant heating of the water flow inside the heating tube 11, a heating element is provided on the outer wall surface of the heating tube 11. The heating element is preferably an electric heating film. The electric heating film can form a resistance layer on the outer wall surface of the heating tube 11 and conduct electricity and heat through the electric heating film so that the electric heating film generates heat and transfers the heat to the water flow inside the heating tube 11, thereby completing the heating effect of the water flow.

[0037] Of course, the heating element can also be an electric heating wire, which can be directly wound around the outer wall of the heating tube 11, and then wrapped with a high-temperature insulating material (such as mica sheets or ceramic fibers) to complete the encapsulation of the heating wire on the outer wall of the heating tube 11. In other embodiments, the heating element can also be a ceramic heating element or other heating elements, which can be selected and arranged according to actual needs.

[0038] In one embodiment, to detachably connect the integrated component 3 to the heating body 1, such as... Figure 2 , Figure 5 and Figure 6As shown, the integrated component 3 has a first connecting seat 32 on the side facing the water inlet end 12 of the heating pipe, and the heating body 1 is sleeved and connected to the first connecting seat 32. The heating body 1 has a first fixing hole 13, and the first connecting seat 32 has a second fixing hole 321. A fastener is connected between the first fixing hole 13 and the second fixing hole 321. Therefore, when connecting the integrated component 3 and the heating body 1, after the heating body 1 is sleeved and connected to the first connecting seat 32, the first fixing hole 13 of the heating body 1 and the second fixing hole 321 of the first connecting seat 32 are connected by fasteners to complete the detachable connection between the integrated component 3 and the heating body 1.

[0039] Preferably, the fastener is a stud, which is used to thread the heating body 1 to the first connecting seat 32.

[0040] Specifically, the outer diameter of the first connecting seat 32 can be set to be the same as the inner diameter of the outer shell of the heating body 1. When the heating body 1 is connected to the first connecting seat 32, the outer shell of the heating body 1 can be fitted onto the first connecting seat 32. Alternatively, the first connecting seat 32 can be configured as an annular groove structure, and the inner diameter of the first connecting seat 32 can be set to be the same as the outer diameter of the outer shell of the heating body 1. When the first connecting seat 32 is connected to the heating body 1, the annular groove of the first connecting seat 32 can be fitted onto the outer shell of the heating body 1.

[0041] Furthermore, after the heating body 1 is connected to the first connecting seat 32, the fixing method between the heating body 1 and the first connecting seat 32 is not limited to the threaded connection of fasteners. A buckle can be arranged in one of the outer shell of the heating body 1 and the first connecting seat 32, and a slot can be arranged in the other, so as to achieve the connection and fixing of the two by using the buckle and the slot.

[0042] Furthermore, after the outer shell of the heating body 1 is connected to the first connecting seat 32, to ensure that the water channel 31 of the integrated component 3 is connected to the water inlet of the heating pipe 11, such as... Figure 3 and Figure 6 As shown, the integrated component 3 also has an outlet pipe 322 on the side facing the water inlet end 12 of the heating pipe. The inner wall of the heating pipe 11 is sleeved on the outer wall of the outlet pipe 322 to connect the outlet of the connecting water channel 31 with the inlet of the heating pipe 11, so that the water in the connecting water channel 31 can flow into the heating pipe 11 for heating.

[0043] like Figure 4As shown, a fixing hoop 111 is fitted on the outer wall of the heating tube 11. An adjusting boss 112 is formed at each end of the fixing hoop 111, and a gap adjusting member 113 is provided between the two adjusting bosses 112. The gap between the two adjusting bosses 112 can be adjusted by adjusting the gap adjusting member 113, thereby adjusting the diameter of the fixing hoop 111 fitted on the outer wall of the heating tube 11. This adjusts the fixing force of the fixing hoop 111 on the heating tube 11 and its internal water outlet pipe 322, ensuring the connection stability of the heating tube 11 when it is fitted onto the water outlet pipe 322.

[0044] The gap adjusting component 113 is preferably a stud nut. Both adjusting bosses 112 have coaxial holes. The stud passes through the two coaxial holes and is threaded to the nut. By adjusting the depth of the stud screwed into the nut, the gap between the two adjusting bosses 112 can be adjusted, and the binding force of the fixing clamp 111 on the heating tube 11 can be adjusted accordingly.

[0045] Furthermore, such as Figure 3 and Figure 4 As shown, a sealing sleeve 114 is provided between the outer wall of the water outlet pipe 322 and the inner wall of the heating pipe 11. The sealing sleeve 114 is used to seal the connection between the water outlet pipe 322 and the heating pipe 11, thereby improving the sealing performance of the connection between the heating pipe 11 and the water outlet pipe 322 and further preventing water leakage.

[0046] Specifically, the sealing sleeve 114 is fitted onto the outer wall of the water outlet pipe 322, and multiple sealing strips are formed on the outer wall of the sealing sleeve 114. The sealing sleeve 114 is sealed to the inner wall of the heating pipe 11 using the multiple sealing strips.

[0047] In embodiments of this utility model, to detachably connect the integrated component 3 to the pump assembly 2, such as... Figure 2 , Figure 5 and Figure 6 As shown, the integrated component 3 has a second connecting seat 33 on the side facing the pump assembly 2. The second connecting seat 33 has a third fixing hole 331, and the outer casing of the pump assembly 2 has a fourth fixing hole 21. Fasteners are connected between the third fixing hole 331 and the fourth fixing hole 21. Therefore, when connecting the integrated component 3 and the pump assembly 2, it is only necessary to align the fourth fixing hole 21 of the pump assembly 2 outer casing with the third fixing hole 331 of the second connecting seat 33 coaxially, and then use fasteners to connect the fourth fixing hole 21 of the pump assembly 2 outer casing and the third fixing hole 331 of the second connecting seat 33 to complete the detachable connection between the integrated component 3 and the pump assembly 2.

[0048] Preferably, the fastener is a stud, and the fourth fixing hole 21 is a threaded countersunk hole formed in the outer shell of the pump unit 2. After the stud passes through the third fixing hole 331 of the second connecting seat 33, it is threadedly connected to the fourth fixing hole 21.

[0049] In embodiments of this utility model, such asFigure 5 and Figure 6 As shown, the integrated component 3 also forms a water inlet connecting pipe 34, and a water inlet channel 341 is formed inside the water inlet connecting pipe 34. A water inlet cavity 332 is formed on the side of the second connecting seat 33 facing the pump unit 2. The water inlet channel 341 communicates with the water inlet cavity 332, and the water inlet cavity 332 communicates with the water inlet of the pump unit 2. The water inlet connecting pipe 34 can be used to connect the water inlet pipe of the electric water faucet. The integrated component 3 can integrate the water inlet pipe, pump unit 2, and heating element 11 into a single structure, further reducing the number of parts during the installation of the electric water faucet and further improving the integration level of the electric water faucet. Furthermore, when the electric water faucet needs water flow, the water inlet connecting pipe 34 is connected to an external pipe so that water flows through the water inlet pipe into the water inlet channel 341 and water inlet cavity 332 of the integrated component 3, and then into the pump cavity.

[0050] In this embodiment, as Figure 2 As shown, a sealing seat 35 is provided on the side of the second connecting seat 33 facing the pump unit 2. The sealing seat 35 forms a sealing ring, and a sealing groove is formed on the side of the pump unit 2 facing the second connecting seat 33. The sealing ring is embedded in the sealing groove. The water inlet of the pump unit 2 is located inside the sealing groove. Therefore, after the integrated component 3 is connected to the pump unit 2, the sealing ring in the sealing seat 35 cooperates with the sealing groove of the pump unit 2 to achieve a sealed connection between the second connecting seat 33 and the pump unit 2, sealing the connection gap between the connecting surfaces of the second connecting seat 33 and the pump unit 2, improving the connection sealing performance between the integrated component 3 and the pump unit 2, and preventing water leakage from the connection gap between the second connecting seat 33 and the pump unit 2.

[0051] Furthermore, such as Figure 6 As shown, the inlet diameter of the connecting water channel 31 is smaller than the outlet diameter of the connecting water channel 31, so as to control the water flow rate input to the connecting water channel 31 and the heating pipe 11 by using the inlet of the connecting water channel 31, so as to avoid the heating efficiency of the heating pipe 11 to be reduced due to the excessive water flow rate input into the heating pipe 11.

[0052] In embodiments of this utility model, such as Figure 6As shown, the side of the integrated component 3 facing the pump assembly 2 is the first connecting surface 323, and the side of the integrated component 3 facing the heating body 1 is the second connecting surface 333. A preset angle is formed between the first connecting surface 323 and the second connecting surface 333, with the preset angle ranging from 0° to 180°. Specifically, the first connecting surface 323 is the side of the second connecting seat 33 facing the pump assembly 2, and the integrated component 3 contacts the pump assembly 2 through the first connecting surface 323; the second connecting surface 333 is the side of the first connecting seat 32 facing the heating body 1, and the integrated component 3 contacts the heating body 1 and the heating tube 11 through the second connecting surface 333. Utilizing the preset angle formed between the first connecting surface 323 and the second connecting surface 333, when the integrated component 3 connects the pump assembly 2 and the heating body 1, the pump assembly 2 and the heating body 1 can be installed at a certain angle, thereby adapting to different layout requirements of the electric water faucet and improving the installation adaptability of the electric water faucet.

[0053] In one specific embodiment, such as Figure 7 As shown, the preset angle between the first connecting surface 323 and the second connecting surface 333 is 0°. At this time, the first connecting surface 323 and the second connecting surface 333 are located on opposite sides of the integrated component 3. When the integrated component 3 connects the water pump and the heating body 1, the heating body 1 and the water pump are located on both sides of the integrated component 3 to meet the needs of electric water faucet arrangement in a narrow installation space.

[0054] In another specific embodiment, such as Figure 8 As shown, the preset angle between the first connecting surface 323 and the second connecting surface 333 is 180°. At this time, the first connecting surface 323 and the second connecting surface 333 are located on the same side of the integrated component 3. When the integrated component 3 connects the water pump and the heating body 1, the heating body 1 and the water pump are located on the same side of the integrated component 3 to meet the needs of electric water faucet arrangement in a small installation space.

[0055] Of course, the preset angle between the first connecting surface 323 and the second connecting surface can also be 30°, 60°, 90°, 120° or 150°, etc., which can be arranged according to actual needs to meet the installation requirements of different installation spaces. The molding shape of the integrated component 3 can be set accordingly.

[0056] In an embodiment of this utility model, a first temperature detection element 14 is provided in the connecting water channel 31, and a second temperature detection element 15 is provided at the outlet of the heating tube 11. The first temperature detection element 14 is used to detect the temperature of the water flow in the connecting water channel 31 that has not flowed into the heating tube 11, and the second temperature detection element 15 is used to detect the temperature of the water flow in the heating tube 11 after heating. The cooperation of the first temperature detection element 14 and the second temperature detection element 15 facilitates the determination of the heating efficiency of the heating tube 11 on the water flow. Specifically, both the first temperature detection element 14 and the second temperature detection element 15 are thermistor temperature sensors (NTC).

[0057] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
