Description

Technical Field

[0001] The utility model relates to the field of bathing appliances, in particular to a zero cold water bathing faucet. Background Art

[0002] As an important part of the family bathroom space, the design, function and user experience of the shower faucet are directly related to the daily quality of the user. In the modern home environment, the shower faucet not only carries the basic functions of adjusting water temperature and controlling water flow, but also is an important element to show the taste and style of home decoration.

[0003] Traditional shower faucet designs often include key components such as hot and cold water regulators, water showers or faucets, and water pipes. The hot and cold water regulators mix cold and hot water to provide users with bathing water of appropriate temperature, while the water showers or faucets are responsible for spraying the regulated water flow onto the user at the appropriate pressure and in the right way, and the water pipes undertake the important task of connecting the water source and the water outlet.

[0004] However, in actual use, some problems with the design of traditional shower faucets gradually emerged. In particular, the water in the water pipe accumulates at the bottom of the pipe due to gravity after bathing, and the water temperature in the pipe gradually decreases over time. This phenomenon is particularly obvious in winter. Due to the low ambient temperature, the water in the pipe cools faster, causing the user to drain some cold water first before waiting for hot water to flow out the next time. This not only wastes water resources, but also reduces the comfort and convenience of bathing.

[0005] In addition, for modern users who pursue efficient and comfortable life, frequent discharge of cold water undoubtedly increases the time cost of bathing, and also affects the consistency and fluency of the bathing experience. Especially in the cold winter, users often need to endure the cold while waiting for hot water, which undoubtedly reduces the pleasure of bathing.

[0006] In response to the above problems, although there are some tentative improvement plans in the industry, such as adding a return water system and optimizing pipe insulation, these plans are often costly, complex to install, and difficult to maintain, making them difficult to be widely used. Therefore, how to effectively solve the problem of water temperature drop in the water pipe while maintaining the basic functions of the shower faucet and improving the comfort and convenience of bathing has become a technical problem that needs to be solved urgently in the current industry.

[0007] With the continuous advancement of science and technology and the continuous improvement of people's requirements for quality of life, higher requirements have been put forward for the technical innovation of shower faucets. From material selection, structural design to intelligent control, it is expected to provide new ideas and solutions for the improvement of shower faucets.

[0008] In summary, the traditional shower faucet design has obvious deficiencies in controlling the water temperature of the water pipe, which brings inconvenience and discomfort to users, especially in winter. Therefore, it is necessary to innovate and optimize the shower faucet to solve the problem of water temperature drop in the water pipe and improve the comfort and convenience of bathing. At the same time, this is also in line with the current trend of the home furnishing industry towards intelligence, efficiency and comfort, which is of great significance to promoting the progress of the entire industry.

[0009] The technical problem to be solved by the utility model is to provide a zero cold water shower faucet. The utility model is provided with an automatic drainage device in the lower end of a connecting water pipe, so that the water in the connecting water pipe can be automatically drained when the faucet is stopped, avoiding the need to drain a section of cold water before use next time.

[0010] The technical solution adopted by the utility model to solve the above technical problems is: a zero cold water shower faucet, including a hot and cold water regulating device, a water outlet device and a control switch, a connecting water pipe is arranged between the hot and cold water regulating device and the water outlet device, a hot and cold water regulating valve is arranged in the hot and cold water regulating device, the hot and cold water regulating valve is connected to the control switch, an automatic drainage device is also arranged in the lower end of the connecting water pipe, the automatic drainage device includes a bracket, a drainage pipe and a movable opening and closing device, the opening and closing device includes a sealing member and a displacement member, and the opening and closing device is axially connected to the bracket; when the connecting water pipe is inflowing water, the water flow impacts the displacement member, so that the sealing member blocks the water inlet of the drainage pipe, and the connecting water pipe works normally; when the connecting water pipe stops inflowing water, the water flow no longer impacts the displacement member, and under the influence of its own weight, the displacement member drives the sealing member and the water inlet of the drainage pipe to separate, a gap is formed between the sealing member and the drainage pipe, and the retained water in the connecting water pipe is discharged to the outside along the gap.

[0011] A further preferred solution of the utility model is: the bracket includes a circular base and a plurality of vertical support members, the middle of the circular base is hollowed out for water inlet, and water-passing gaps are provided between adjacent vertical support members and on the outer sides of the vertical support members.

[0012] A further preferred solution of the utility model is that the sealing member passes through the gap between two adjacent vertical support members and contacts the water inlet of the drainage pipe.

[0013] A further preferred solution of the utility model is that the sealing member is hemispherical and is inserted into the water inlet to achieve sealing.

[0014] A further preferred solution of the utility model is as follows: the displacement member is a circular structure arranged transversely, the displacement member is arranged above the vertical support member, and a displacement gap is arranged between the displacement member and the vertical support member for the displacement member to move.

[0015] A further preferred solution of the utility model is: the sealing member is installed on the connecting member, the lower end of the connecting member is axially connected to the vertical supporting member, and the upper end of the connecting member is fixed to the displacement member.

[0017] A further preferred solution of the utility model is: the drainage pipe is arranged at the rear side of the connecting water pipe

[0018] The utility model has a newly added automatic drainage device. When the connecting water pipe stops inflowing water, the water flow no longer impacts the displacement member. Under the influence of its own weight, the displacement member will drive the sealing member to separate from the water inlet of the drainage pipe. At this time, a gap will be formed between the sealing member and the drainage pipe, and the remaining cold water in the connecting water pipe can be smoothly discharged to the outside along this gap. This process does not require manual operation by the user, and fully realizes drainage automation, improves the comfort of bathing, and greatly enhances the user experience.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] In traditional shower faucets, users often face a common and annoying problem: after turning off the faucet, due to the cooling of the water in the connecting water pipe 2, a certain amount of cold water must be drained before enjoying warm hot water the next time the faucet is used. This not only wastes time, but also wastes water resources. However, this zero cold water shower faucet completely solves this problem by introducing the automatic drainage device 1.

[0027] First, zero cold water discharge effect

[0028] like Figure 1-Figure 6 As shown, the zero cold water shower faucet includes a hot and cold water regulating device 21, a water outlet device 22 and a control switch 23. A connecting water pipe 2 is arranged between the hot and cold water regulating device and the water outlet device. A hot and cold water regulating valve is arranged in the hot and cold water regulating device 11. The hot and cold water regulating valve is connected to the control switch. An automatic drainage device 1 is also arranged in the lower end of the connecting water pipe.

[0029] When the connecting water pipe 2 stops inflowing, the water flow no longer impacts the displacement member 9, and the displacement member 9, under the influence of its own weight, will drive the sealing member 3 to separate from the water inlet of the drain pipe 4. At this time, a gap will be formed between the sealing member 3 and the drain pipe 4, and the cold water remaining in the connecting water pipe 2 can be smoothly discharged to the outside through this gap. This process does not require manual operation by the user, and is fully automated, bringing great convenience to the user.

[0030] In addition, since the cold water can be discharged in time after each use, the user can quickly enjoy warm hot water when using it next time without waiting for the cold water to be discharged. This not only improves the comfort of bathing, but also greatly enhances the user experience.

[0031] Second, the stability effect of automatic drainage device 1

[0032] The automatic drainage device 1 is exquisitely designed and stable, ensuring normal operation in various usage scenarios. The bracket 5, as the basis of the entire device, adopts a circular base 6 and a plurality of vertical support members 7, so that the device can be stably installed in the connecting water pipe 2. The hollow design of the middle part of the circular base 6 not only ensures the smooth entry of water flow, but also makes the structure of the entire device more compact.

[0033] Water gaps 8 are provided between and outside the vertical supports 7, which not only provide channels for water flow, but also enhance the overall stability of the bracket 5. The seal 3 passes through the gap between two adjacent vertical supports 7 and is in close contact with the water inlet of the drain pipe 4, achieving a good sealing effect. This design not only ensures the smoothness of drainage, but also avoids water leakage.

[0034] At the same time, the horizontal circular structure of the displacement member 9 and the displacement gap 10 between the displacement member 9 and the vertical support member 7 enable the displacement member 9 to move freely under the impact of the water flow, thereby realizing the opening and closing of the sealing member 3. This structural design ensures both the flexibility of the device and its stability during use.

[0035] Third, Sealing Effect

[0036] The sealing element 3 is a key component of the automatic drainage device 1, and its sealing effect directly affects the performance of the entire device. This zero cold water shower faucet adopts a hemispherical sealing element 3 design, which can better adapt to the shape of the water inlet and achieve a tighter fit. When the sealing element 3 is inserted into the water inlet, it can form an effective sealing barrier to prevent water from leaking from the gap.

[0037] In addition, the seal 3 is mounted on the connecting member 11, and the lower end of the connecting member 11 is axially connected to the vertical support member 7, and the upper end is fixed to the displacement member 9. This connection method not only ensures the stability of the seal 3, but also enables it to move freely under the drive of the displacement member 9. When the water flow hits the displacement member 9, the seal 3 can quickly block the water inlet; and when the water flow stops, the seal 3 can be separated from the water inlet under the influence of the self-weight of the displacement member 9. This flexible movement method enables the seal 3 to achieve a good sealing effect in different states.

[0038] Fourth, installation stability effect

[0039] In order to ensure that the automatic drainage device 1 will not shake or shift due to the impact of water flow during use, an outward protrusion structure 12 is specially designed on the top of the vertical support member 7. These protrusion structures 12 can be close to the inner wall of the connecting water pipe 2, thereby increasing the contact area and friction between the device and the water pipe, so that the device can be installed in the connecting water pipe 2 more stably.

[0040] This design not only improves the installation stability of the automatic drainage device 1, but also reduces the risk of failure caused by shaking or displacement. The user does not need to worry about the device falling off or shifting during use, thereby further enhancing the safety and reliability of use.

[0041] Fifth, aesthetic effect

[0042] In addition to the functional improvement, this zero cold water shower faucet also pays attention to the aesthetic design. The drain pipe 4 is cleverly arranged at the rear side of the connecting water pipe 2. This hidden design makes the appearance of the whole faucet more simple and generous, and the exposure of the drain pipe 4 will not destroy the overall beauty.

[0043] At the same time, this design also avoids the collision and damage that may be caused by the drain pipe 4 during use, further extending the service life of the faucet. While appreciating its beautiful appearance, the user can also enjoy the comfortable bathing experience it brings.

[0044] In summary, this zero cold water shower faucet realizes the automatic discharge of residual water in the connecting water pipe 2 by introducing the automatic drainage device 1, which brings many conveniences and comfortable experiences to users. At the same time, its stable automatic drainage device 1, good sealing effect, installation stability and aesthetic design all make this faucet have great competitive advantages and development potential in the market. It is believed that with the continuous advancement of technology and the continuous development of the market, this zero cold water shower faucet will show a broader application prospect and market space in the future.

[0045] The above is a detailed introduction to the zero cold water shower faucet provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the utility model and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
