Description

Technical Field

[0001] The utility model relates to the technical field of water outlet equipment, in particular to an installation structure of a temperature sensor and a water outlet faucet with the same. Background Art

[0002] Currently, temperature sensors at the outlet of electric faucets play an important role in automatically regulating water temperature, preventing scalding accidents, reducing energy consumption, and extending appliance life. With the continuous advancement of sensor technology and the widespread application of intelligent control, the performance and user experience of electric faucets have been further improved.

[0003] An electric water faucet in the prior art has a temperature sensor arranged in a water outlet channel. The temperature sensor is fixed and installed in a position by a rubber sleeve passed through the water outlet channel. At the same time, the rubber sleeve needs to be fixed with an external fixed connecting component to fix it. In the assembly step of passing the rubber sleeve, it is difficult to determine whether the rubber sleeve is assembled in place, especially under manual operation. If it is not assembled in place, the part of the rubber sleeve extending outside the assembly position will affect the subsequent assembly of the external connecting part and the outer shell of the electric water faucet. In addition, due to the flexible nature of the rubber sleeve, after long-term use, there is a risk that the temperature sensor will deviate from the optimal temperature detection position.

[0038] 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. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0039] It should be understood that although terms such as upper, middle, lower, top end, one end, etc. appear in this article to describe various components, these components are not limited by these terms. These terms are only used to distinguish the components from each other for easy understanding, rather than to define any directional or sequential limitations.

[0040] As Figure 1-10 shown, an installation structure of a temperature sensor includes:

[0041] Water outlet end cover 1, the water outlet end cover 1 includes an end cover body 1.4 and a water outlet end pipe 1.5 provided on the top of the end cover body 1.4. A water outlet channel 1.1 is provided in the water outlet end cover 1, a temperature sensor 2 is provided in the water outlet channel 1.1, the water outlet channel 1.1 communicates between the water outlet end pipe 1.5 and the end cover body 1.4, and an installation opening is provided on the end cover body 1.4;

[0042] Installation assembly, including an installation seat 3 fixedly provided on the inner side of the water outlet end cover 1 and a connecting member 4 inserted into the installation seat 3 from the outside. The connecting member 4 is inserted into the end cover body 1.4 through the installation opening and fixedly connected to the installation seat 3. A placement cavity 4.1 with one end open is provided in the connecting member 4 for placing the temperature sensor 2.

[0043] From Figure 3 and Figure 4It can be seen that as a further implementation of the cooperation between the mounting base 3 and the connecting member 4, at least one anti-retreat convex portion 3.1 is provided on the mounting base 3, and an anti-retreat cooperation portion 4.2 that is engaged with the anti-retreat convex portion 3.1 is provided at the end of the connecting member 4. During the installation stroke of the connecting member 4, the anti-retreat convex portion 3.1 and the anti-retreat cooperation portion 4.2 cooperate with each other as the connecting member 4 is inserted, and the connecting member 4 is allowed to further travel along the insertion direction until the connecting member 4 abuts against the limit position of the mounting base 3. In the direction away from the insertion direction, the connecting member 4 and the mounting base 3 are fixed to each other through the snap-fit of the anti-retreat cooperation portion 4.2 and the anti-retreat convex portion 3.1.

[0044] Preferably, the number of the anti-retreat convex portions 3.1 is multiple and they are arranged in sequence along the insertion direction of the connecting member 4. The number of the anti-retreat cooperation portions 4.2 corresponds to that of the anti-retreat convex portions 3.1 and they are engaged one by one along the insertion direction of the connecting member 4. As the connecting member 4 is inserted to the limit position, the connecting member 4 is reliably held in the mounting base 3. Of course, in some other embodiments, the fixation of the connecting member 4 and the mounting base 3 is not limited to multiple anti-retreat convex portions 3.1 and anti-retreat cooperation portions 4.2. The cooperation of one anti-retreat convex portion 3.1 and one anti-retreat cooperation portion 4.2 can also achieve the fixation of the connecting member 4. This embodiment shows the situation where the connecting member 4 can be flush with the end cover body 1.4 based on the mutual cooperation of multiple anti-retreat convex portions 3.1 and anti-retreat cooperation portions 4.2.

[0045] Through the above settings of multiple anti-retreat convex portions 3.1 and anti-retreat cooperation portions 4.2, it is beneficial to improve the structural strength of the mounting base 3 and the connecting member 4, as well as the stability of their mutual cooperation.

[0046] As an example, both the anti-retreat convex portion 3.1 and the anti-retreat cooperation portion 4.2 are set as tooth-like shapes that are obliquely opposite to each other, and a first guiding inclined surface 8 is provided on the anti-retreat convex portion 3.1 and the anti-retreat cooperation portion 4.2 along the insertion direction, so as to provide an obvious sense of being in place during the assembly process of the connecting member 4.

[0047] Continue Figure 3 and Figure 4 Moreover, as a further implementation of the mounting base 3, the mounting base 3 includes retaining walls 3.2 that are oppositely arranged on both sides of the connecting member 4. The anti-retreat convex portion 3.1 is provided on the inner side of the retaining wall 3.2. Preferably, the anti-retreat cooperation portion 4.2 is provided on both sides of the connecting member 4 and cooperates with the retaining walls 3.2 on the outer sides, so as to improve the compactness of their cooperation. In addition, the retaining walls 3.2 on both sides play a limiting role on the anti-retreat cooperation portion 4.2 and the connecting member 4, and form an opening for the connecting member 4 to be inserted, so as to facilitate guiding the connecting member 4 to be inserted, so that the connecting member 4 can be limited between the installation opening and the two retaining walls 3.2, thereby restricting the yaw of the connecting member 4.

[0048] like Figure 8 As shown, as a further embodiment of the connecting member 4, at least two clamping arms 4.3 are extended from the end of the connecting member 4, the clamping arms 4.3 are arranged at intervals, and the retaining fitting portion 4.2 is arranged on the outside of the clamping arms 4.3. The two clamping arms 4.3 extend between the two retaining walls 3.2 and fit one by one.

[0049] Preferably, the clamping arms 4.3 have a tendency to expand outward, and the clamping fitting portion tends to fit with the clamping protrusion through the structural characteristics of the connecting member 4 itself, so as to ensure the position reliability of the connecting member 4 in the installed state.

[0050] In order to further improve the tightness of the fit between the clamping arm 4.3 and the retaining wall 3.2, a guide portion 3.3 is provided between the retaining wall 3.2, which forces the retaining fitting portion 4.2 to deviate toward the retaining protrusion 3.1 and keeps the retaining fitting portion 4.2 engaged with the retaining protrusion 3.1.

[0051] Among them, the number of the clamping arm 4.3 can be one, and the clamping arm 4.3 is specifically arranged between the guide part 3.3 and the retaining wall 3.2, and then the clamping arm 4.3 is pressed toward the retaining wall 3.2 through the guide part 3.3 to reduce the gap between the retaining protrusion 3.1 and the retaining fitting part 4.2.

[0052] Among them, corresponding to the two clamping arms 4.3, the guide part 3.3 is arranged between the two clamping parts. When the connecting member 4 is inserted, the guide part 3.3 corresponds to the middle part of the two clamping arms 4.3 and stretches the clamping arms 4.3 toward the outside, that is, close to the position of the retaining wall 3.2, and the end of the clamping arm 4.3 abuts between the retaining wall 3.2 and the guide part 3.3, thereby reducing the gap between the clamping arm 4.3 and the retaining wall 3.2, so that the two clamping arms 4.3 are both clamped between the guide part 3.3 and the retaining wall 3.2.

[0053] Specifically, a second guiding slope 9 is provided on the opposite surface of the clamping wall and the guide portion 3.3, which facilitates the insertion of the connecting member 4 and improves the tightness of the end of the clamping arm 4.3 between the guide portion 3.3 and the retaining wall 3.2.

[0054] from Figure 4 As can be seen in the figure, specifically, a limiting portion 4.4 is provided at the corresponding opening of the connecting member 4. The limiting portion 4.4 extends radially outward and abuts against the outer wall of the water outlet end cover 1. A limiting seat 1.2 is extended on the water outlet end cover 1. The contour of the limiting seat 1.2 matches the limiting portion 4.4. The limiting portion 4.4 is placed in the limiting seat 1.2, and the end position of the connecting member 4 is further constrained by the limiting seat 1.2.

[0055] Preferably, the end face of the limiting part 4.4, that is, the outer end face of the connecting member 4 is flush with the limiting seat 1.2, which is convenient for identifying the proper installation of the connecting member 4. In addition, it is also helpful for the installation of other components outside the water outlet end cover 1, reducing the risk of interference.

[0056] Furthermore, a sealing ring 5 is abutted between the limiting seat 1.2 and the limiting part 4.4. As the connecting member 4 is inserted in place, the sealing ring 5 is tightly abutted on the limiting part 4.4 to ensure the sealing between the connecting member 4 and the water outlet end cover 1.

[0057] Specifically, the connecting member 4 is made of heat-conducting plastic material, which improves the structural strength of the connecting member 4, ensures the sensing accuracy of the water outlet temperature by the temperature sensor 2. In addition, the plastic connecting member 4 is beneficial to maintaining its position on the water outlet end cover 1 and the stability of the cooperation and fixation with the mounting seat 3, thus ensuring the position stability of the temperature sensor 2 in the connecting member 4.

[0058] Refer to Figure 5 and Figure 6 , this embodiment further explains the position of the connecting member 4 in the water outlet end cover 1.

[0059] The water outlet end cover 1 includes a spaced part 1.3, which is specifically arranged at the junction of the water outlet end pipe 1.5 and the end cover main body 1.4. And the spaced part 1.3 is a platform arranged in a plane. The spaced part 1.3 specifically extends from one inner wall side of the water outlet end pipe 1.5 to the other inner wall side. There is a space between one side of the spaced part 1.3 and the water outlet end pipe 1.5, thus defining the water outlet channel 1.1. The mounting seat 3 is arranged on the spaced part 1.3. In this way, it is beneficial to arrange the position of the mounting seat 3 on the water outlet end cover 1, so that the mounting seat 3 can extend on the end face of the spaced part 1.3, and further prevent the rotation of the connecting member 4 in the circumferential direction.

[0060] Preferably, the upper and lower end faces of the connecting member 4 have flat parts.

[0061] Specifically, the placement cavity 4.1 is arranged in the area of the connecting member 4 corresponding to the water outlet channel 1.1, and the anti-rotation and engagement part 4.2 is arranged in the area of the connecting member 4 corresponding to the spaced part 1.3. The parts extending from the end of the sub-placement cavity 4.1 on the connecting member 4 are all clamping arms 4.3 to ensure the structural strength of the anti-rotation and engagement part 4.2, while the area corresponding to the water outlet channel 1.1 is a thin wall, which is convenient for monitoring the water outlet water temperature.

[0062] As Figures 1 to 3 shown, a water outlet faucet includes the installation structure of the above-mentioned temperature sensor 2, including:

[0063] The main housing 6, the electric control cavity 6.1 provided on the surface of the main housing 6, and the protective housing 7 buckled on the electric control cavity 6.1. An electric control module for arranging a water faucet is arranged in the electric control cavity 6.1, and the protective housing 7 shields the electric control cavity 6.1 to play a protective role.

[0064] Wherein, a heating component 10 is further arranged in the main housing 6.

[0065] Wherein, the electric control cavity 6.1 includes an installation area 6.3 and a wiring area 6.2. The electric control module is arranged in the installation area 6.3. The wiring area 6.2 also extends on the main housing 6 and the water outlet end cover 1. The protective housing 7 also covers the connecting member 4 and communicates with the wiring area 6.2, so as to form a channel between the protective cover and the main housing 6 for the line of the temperature sensor 2 to be connected to the installation area 6.3.

[0066] Referring to Figure 9 and Figure 10 As shown, as a further implementation manner of buckling the protective housing 7 and the main housing 6, a channel 6.4 for the line to pass through is provided on the wiring area 6.2 and the installation area 6.3. The channel 6.4 has at least one section of a clamping groove part 6.41. A clamping block part 7.1 is provided on the protective housing 7 corresponding to the clamping groove part 6.41. The clamping block part 7.1 is embedded in the clamping groove part 6.41, and an abutting flange 6.42 extends out from the outer edge of the clamping groove part 6.41. An abutting groove 7.2 matching the abutting flange 6.42 is provided on the clamping block part 7.1, so as to realize the mutual buckling of the protective housing 7 and the main housing 6. Among them, the abutting flange 6.42 and the outer edge of the clamping block part 7.1 form a regular contour consistent with the main housing 6.

[0067] Preferably, the clamping groove part 6.41 and the clamping block part 7.1 are arranged above the electric control cavity 6.1 and correspond to the junction position of the water outlet end cover 1 and the main housing 6.

[0068] Further, a positioning recess 7.3 is provided on the periphery of the protective housing 7 corresponding to the electric control cavity 6.1, and a positioning protrusion 6.5 corresponding to the positioning recess 7.3 is provided on the periphery of the electric control cavity 6.1, so as to realize the positioning cooperation between the protective housing 7 and the main housing 6.

[0069] Through the above improvements, after docking the protective housing 7 and the electric control cavity 6.1, only need to buckle the clamping block part 7.1 into the clamping groove part 6.41, which is convenient for installation and does not require additional bolt connectors.

[0070] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
