Description

Technical Field

[0001] This utility model relates to the field of water tap technology, specifically to a water outlet device with high sealing performance. Background Technology

[0002] Currently, with the improvement of people's living standards, plug-in electric water faucets are becoming increasingly popular in the market due to their installation-free and easy-to-use features.

[0003] This type of electric water faucet is used for installation at the water outlet of a water tap. It includes an electric heating element assembly connected to the water outlet housing of the faucet. Existing electric heating element assemblies typically have two connection terminals at both ends for providing electrical connections. These terminals usually have an outer diameter larger than the outer diameter of the heating element assembly itself, making it difficult to fix and limit the heating element assembly within a single outlet shell. This is especially problematic when water channels need to be formed along the length of the outlet shell. The inserts used to form these water channels are difficult to remove after the outlet shell is formed, affecting the quality of the shell's construction. Therefore, existing water outlet shells are typically split into two interlocking sub-shells along their length to facilitate production. However, this method results in an excessively long mating surface between the two sub-shells, requiring the configuration of corresponding sealing rings. Furthermore, these sealing rings are often too large, and during long-term use, they are prone to local deformation or fatigue aging due to water pressure fluctuations and temperature changes. This leads to uneven distribution of sealing pressure, which negatively impacts the reliability and stability of the seal and poses a risk of leakage. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document 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 ease of understanding, and are not used to define any directional or sequential restrictions.

[0022] like Figure 1-7 As shown, a highly airtight water outlet device includes: The water outlet housing includes a first housing 1 and a second housing 2 that are spliced ​​together, and a sealing connector 3 that connects the first housing 1 and the second housing 2. The first housing 1 and the second housing 2 are provided with opposing splicing parts 4. The sealing connector 3 is arranged around the splicing parts 4 and abuts against the splicing parts 4. The first housing 1 and the second housing 2 are fixedly connected by a tensioning member, thereby tightly fitting the sealing connector 3 between the first housing 1 and the second housing 2. The outlet shell is provided with a water channel structure 1.1 for forming a water inlet channel. The water channel structure 1.1 extends through one of the first shell 1 or the second shell 2. The other of the first shell 1 or the second shell 2 is provided with a water channel mating part 2.1. There can be multiple water channel structures 1.1. The water channel mating part 2.1 closes or connects one of the water channel structures 1.1 according to the extension arrangement of the water channel structures 1.1. For example, if one of the water channel structures 1.1 needs to extend from the first shell 1 to the second shell 2, then the water channel mating part 2.1 connects with the water channel structure 1.1 as a pipe structure. Or, if one of the water channel structures 1.1 needs to be stopped at the splice part 4 of the first shell 1, then the water channel mating part 2.1 closes with the water channel structure 1.1 as a sealing structure.

[0023] In this embodiment, to further ensure the sealing of the waterway structure 1.1 and the waterway mating part 2.1, the sealing connector 3 has a waterway joint 3.1 surrounding the waterway mating part 2.1. The waterway joint 3.1 is preferably wrapped around the waterway structure 1.1 or the waterway mating part 2.1. The waterway joint 3.1 abuts between the waterway structure 1.1 and the waterway mating part 2.1 and tightly connects the splice part 4 of the first shell 1 and the second shell 2.

[0024] like Figure 1As shown, preferably, the water outlet shell is arranged laterally about the water outlet head, and the water inlet channel and the heating chamber 5 inside the water outlet shell also extend laterally. In this embodiment, the water outlet shell is divided about the longitudinal section to form a first shell 1 and a second shell 2 with left and right divisions, and a joint part 4 with concave and convex structure is formed between the splicing surfaces of the first shell 1 and the second shell 2. A sealing connector 3 is provided between the two splicing parts 4. The sealing connector 3 plays the role of sealing and connecting the splicing parts 4. In addition, the water inlet channel and the heating chamber 5 inside the water outlet shell are also divided by the splicing part 4. The sealing connector 3 also plays the role of sealing and fitting between the water channels.

[0025] In a further embodiment, the outlet shell is preferably arranged in a straight line, which is more conducive to controlling the overall center of gravity of the outlet shell. Of course, the outlet shell can also be set to other shapes, but the corresponding parts of the water inlet channel and the heating chamber 5 are arranged horizontally. The water inlet channel is preferably set at the top of the outlet shell, and the heating chamber 5 of the outlet shell is defined below the water inlet channel. The ends of the water inlet channel and the heating chamber 5 are connected by a vertical water passage 2.8.

[0026] In the above embodiments, at least one of the waterway structure 1.1 and the waterway mating part 2.1 protrudes relative to the splicing part 4 where it is located, thereby allowing the waterway joint part 3.1 to be better enclosed and arranged, and the relative waterway structure 1.1 and the waterway mating part 2.1 are inserted and fitted together to improve the tightness.

[0027] like Figure 3 As shown, the sealing connector 3 has a first joint portion 3.2 that extends toward the splice portion 4 and is at least partially inserted into the first housing 1 and / or the second housing 2.

[0028] That is, the first joint 3.2 extends in the lateral opposite direction, including but not limited to being inserted into the first housing 1, or the second housing 2, or the first housing 1 and the second housing 2. Correspondingly, the first housing 1 and the second housing 2 are provided with a groove structure that matches the first joint 3.2. The first joint 3.2 and the groove structure are preferably provided around the water channel structure 1.1 or the water channel mating part 2.1 so that the sealing connector 3 forms a sealing engagement relationship between the two opposite splicing parts 4. The extended first joint 3.2 further increases the shear resistance and mating stability of the sealing connector 3.

[0029] The outline dimension of the first joint 3.2 can be slightly larger than the groove dimension on the splicing part 4 to achieve an interference fit of the sealing connector 3. For this purpose, a gap is provided between the opposite splicing parts 4 to allow the deformation of the sealing connector 3 to be released. Of course, the deformation release part of the sealing connector 3 is also squeezed by the splicing part 4 to form a dense connection.

[0030] like Figure 6 and Figure 7 As shown, specifically, the splicing part 4 has a housing mating part 4.2 extending outside the waterway structure 1.1 and the waterway mating part 2.1. The housing mating part 4.2 can extend in the direction of the outline plane of the splicing part 4 or in the opposite direction of the splicing part 4. Based on the first joint part 3.2 described above, to ensure the sealing fit of the splicing part 4, the housing mating part 4.2 is formed on the opposite end faces of the first housing 1 and the second housing 2. Further refer to Figure 3 The gaps mentioned above are spaced between the opposing housing mating parts 4.2. The sealing connector 3 also has a second joint part 3.4 that abuts against the opposing housing mating parts 4.2. The second joint part 3.4 preferably extends in the contour plane direction of the splicing part 4 and protrudes or is flush with the outer contour of the splicing part 4. The second joint part 3.4 is integrally formed with the first sealing part on the sealing connector 3 and provides a deformation release area for the compression fit of the splicing part 4.

[0031] from Figure 6 and Figure 7 As can be seen from the above, in some embodiments, the first joint 3.2 constitutes the waterway joint 3.1, and adjacent waterway joints 3.1 are connected through the first joint 3.2. In other words, the waterway joint 3.1 also extends in the opposite direction to the splicing part 4, thereby improving the sealing of the waterway structure 1.1 and the waterway mating part 2.1.

[0032] Further reference Figure 4 and Figure 5 As shown, further, in this embodiment, for the splicing part 4 on the first housing 1, the housing mating part 4.2 on it extends relative to the water channel structure 1.1, thereby forming a concave groove structure on the end face of the splicing part 4 of the water channel structure 1.1. For the splicing part 4 on the second housing 2, the water channel structure 1.1 on it extends relative to the housing mating part 4.2 in the splicing direction, thereby allowing the sealing connector 3 to be sleeved on the second housing 2 and placed in the first housing 1.

[0033] Through the above improvements, an integrated seal is achieved through the sealing connector 3. The adjacent waterway joints 3.1 and the second joint 3.4 are connected into an integral sealing frame through the first joint 3.2, which makes the sealing force distribution more uniform and consistent. The pressure on any waterway interface can be distributed by the overall structure, avoiding excessive local stress concentration that could lead to over-compression or seal failure, and improving the consistency and stability of the seals of all interfaces.

[0034] In addition, it is worth mentioning that the sealing connector 3 also serves as a connecting frame between the opposing splicing parts 4.

[0035] like Figure 6 and Figure 7 ,as well as Figures 9 to 11 As shown, the water channel structure 1.1 and the water channel mating part 2.1 are integrally formed on the water outlet shell, that is, the water inlet channel is integrally formed on the water outlet shell, preferably formed on the top wall of the water outlet shell, so as to create a heating chamber 5 for cleaning inside the water outlet shell. The splicing part 4 is provided with a water cavity outline part 4.1, and the water outlet shell is also provided with a water cavity structure 6 extending from the water cavity outline part 4.1. The opposing water cavity outline parts 4.1 are interlocked and fitted together. The water cavity outline parts 4.1 are spliced ​​together and abut against the sealing connector 3 to form the heating chamber 5. The shape of the first joint part 3.2 matches the water cavity outline part 4.1. The water channel structure 1.1 forms part of the boundary of the water cavity outline part 4.1. Specifically, the water cavity outline part 4.1 abuts against the first joint part 3.2.

[0036] In addition, thanks to the left and right split first shell 1 and second shell 2, the hot water inlet channel 1.3 integrally formed on the water outlet shell can be split together, which facilitates the mold design of the first shell 1 and the second shell 2 and helps to improve the molding quality of the first shell 1 and the second shell 2.

[0037] Specifically, the sealing connector 3 is also provided with a water cavity joint 3.3 that matches the water cavity contour 4.1. The first joint 3.2 constitutes the water cavity joint 3.3, and the water cavity joint 3.3 is connected with the water channel joint 3.1. The sealing connector 3 realizes the sealing partition of the water inlet channel and the heating cavity 5. The connection between the water cavity joint 3.3 and the water channel joint 3.1 means that a single sealing connector 3 completes the contour sealing of each part of the entire internal flow channel system of the water outlet shell, forming a complete sealing ring, providing reliable sealing and pre-positioning for the fit of the splicing part 4.

[0038] Reference Figure 6 and Figure 7 As shown, specifically, a tensioning member is provided on the housing mating part 4.2. The tensioning member is preferably a bolt connection. As an example, the first housing 1 is provided with a first hole 1.4, and the second housing 2 is provided with a second hole 2.5. An internal thread is provided in the first hole 1.4. The tensioning member passes through the second joint 3.4. The second joint 3.4 is provided with a third hole 3.5. The tensioning member passes through the second hole 2.5 from one side of the second housing 2, passes through the third hole 3.5 of the sealing connection 3, and enters the first housing 1. It is threadedly connected to the first hole 1.4, thereby connecting the first housing 1 and the second housing 2.

[0039] Specifically, the third hole 3.5 is provided on the second joint 3.4, thereby further compressing and sealing the connector 3 in the opposite direction of the splicing part 4.

[0040] In this embodiment, by setting the tensioning member on the sealing connector 3, the sealing function is combined with the mechanical connection function. The second joint 3.4 provides a flat pressing surface between the housing mating parts 4.2. The tensioning member passes through it, and the resulting locking force acts directly on the sealing area, ensuring that the compressive force applied by the first housing 1 and the second housing 2 to the sealing connector 3 is constant and sufficient. The second joint 3.4, which extends in profile, can compact the first joint 3.2 towards the center, achieving a long-term effective seal.

[0041] As a further embodiment of the waterway connection and waterway mating part 2.1, such as Figure 6 As shown, the water channel structure 1.1 includes a cold water inlet channel 1.2 and a hot water inlet channel 1.3 formed on the first housing 1. Both the cold water inlet channel 1.2 and the hot water inlet channel 1.3 extend along the lateral extension direction of the first housing 1 itself and form an open portion on the splicing part 4. The open portion is recessed relative to the housing fitting part 4.2 of the first housing 1 and flush with the water cavity outline part 4.1. like Figure 7 As shown, the waterway assembly 2.1 includes a first sealing member 2.2 protruding from the splicing end face of the second housing 2 and a connecting pipe portion 2.3, further referring to... Figure 3 and Figure 5 As shown, the first sealing member 2.2 and the connecting pipe 2.3 are arranged adjacent to each other and are inserted into the water channel joint 3.1. The first sealing member 2.2 is inserted into the cold water inlet channel 1.2, and the connecting pipe 2.3 is inserted into and connected to the hot water inlet channel 1.3. The radial extrusion force applied to the inserted first sealing member 2.2 and the connecting pipe 2.3 by the surrounding water channel joint 3.1 achieves sealing, which is conducive to the rapid assembly of the first housing 1 and the second housing 2.

[0042] Specifically, the water channel mating part 2.1 is inserted into the water channel structure 1.1, and the water channel mating part 2.1 has an assembly groove 2.4 on its periphery for the sealing connector 3 to be fitted into. In this embodiment, the assembly groove 2.4 is specifically disposed on the second housing 2 and is formed between the housing mating part 4.2 and the water cavity contour part 4.1. Adjacent water channel mating parts 2.1 on the second housing 2 are spaced apart by slot structures, forming a portion of the assembly groove 2.4. For the first housing 1, its water cavity contour part 4.1 is recessed within the housing mating part 4.2, from... A recessed mounting groove 2.4 is formed on the splicing part 4 of the first housing 1 for the sealing connector 3 to fit. The mounting groove 2.4 provides precise installation positioning for the sealing connector 3, which allows the sealing connector 3 to be pre-positioned on the first housing 1 and to abut against the open end face of the first joint 3.2 and the water channel structure 1.1. This simplifies the assembly process and ensures that the sealing connector 3 is always in the correct design position and will not shift due to manual operation, greatly improving the consistency of production yield and sealing reliability.

[0043] Preferably, the lengths of the waterway mating portion 2.1 and the water cavity contour portion 4.1 are greater than the length of the first joint portion 3.2.

[0044] from Figure 3 As can be seen, specifically, the lower part of the water channel mating part 2.1 is provided with a support bottom 2.6, which extends to the water channel structure 1.1 and passes through the bottom of the water channel joint 3.1. The support bottom 2.6 constitutes part of the water cavity outline part 4.1 to provide support and limit the sealing connection 3 around the water cavity outline part 4.1.

[0045] like Figure 13 and Figure 14 ,as well as Figure 16 As shown, as a further embodiment of the heating chamber 5, the heating chamber 5 is provided with a heating tube assembly 7. The ends of the first housing 1 and the second housing 2 are provided with a first fixing space 1.5 and a second fixing space 2.7 for accommodating the ends of the heating tube assembly 7. The ends of the heating tube assembly 7 are provided with a sealing ring 7.1 that abuts against the first fixing space 1.5 and the second fixing space 2.7.

[0046] In this embodiment, the heating tube assembly 7 specifically refers to the heating tube assembly 7, which has a tube portion with a first outer diameter and an end seat 7.2 with a second outer diameter. Thanks to the left-right split configuration of the first housing 1 and the second housing 2, there is no need to set a completely through fixed space on the first housing 1 and the second housing 2. It is only necessary to allow the electrical connection part on the end seat 7.2 to extend out, which improves the assembly reliability of the heating tube assembly 7. During the assembly process, the left-right split first housing 1 and the second housing 2 are spliced ​​and embraced at both ends of the heating tube assembly 7.

[0047] like Figures 8 to 16 As shown, to further explain the water flow inside the outlet housing, an inlet 8 is provided at the top of the outlet housing, which is connected to a faucet 13. An outlet 9 is provided at the bottom of the outlet housing. A control valve 10 is provided at the end of the first housing 1. The inlet 8, the cold water inlet channel 1.2, and the control valve 10 are connected in sequence. The control valve 10 controls the connection between the cold water inlet channel 1.2 and the hot water inlet channel 1.3 by rotating the gear. The connecting pipe 2.3 located on the second housing 2 connects to the hot water inlet channel 1.3. A water pressure switch 11 is provided at one end of the connecting pipe 2.3. The water pressure switch 11 includes a valve diaphragm 11.1 that stops at the end of the connecting pipe 2.3, and a conductive sheet assembly 11.2 that abuts against the back water surface of the valve diaphragm 11.1. The conductive sheet assembly 11.2 is connected to the heating tube assembly 7. The second housing 2 is also provided with a water passage 2.8, which connects to the heating tube assembly 7 through a water inlet 2.9. The water-facing surface of the cavity 5 and the valve diaphragm 11.1 is connected to the stop of the connecting pipe 2.3. When the control valve 10 is set to the hot water position, the incoming water flows through the inlet 8 into the cold water inlet channel 1.2 and the hot water inlet channel 1.3 in sequence. Then the incoming water flows onto the valve diaphragm 11.1. Under the action of the water flow, the valve diaphragm 11.1 presses against the conductive sheet group 11.2, so that the heating tube group 7 is energized. Then the water flows through the water passage 2.8 into the heating cavity 5 and is heated. Finally, it is discharged from the outlet 9.

[0048] Preferably, a one-way valve 12 is also provided in the water passage 2.8. The one-way valve 12 is used to prevent the water in the heating chamber 5 from flowing back to the water pressure switch 11. The control valve 10 is a conventional valve body in the prior art. It realizes the connection of cold water or hot water by rotating the gear. It will not be described in detail here.

[0049] Of course, the control valve 10 also has a cold water setting. A cold water outlet channel 16 is provided between the cold water inlet channel 1.2 and the cold water outlet channel 1.6. The cold water outlet channel 1.6 is directly connected to the heating chamber 5.

[0050] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
