Description

Technical Field

[0001] The invention relates to the technical field of bathroom equipment, and in particular to a quick water-stopping shower head. Background Art

[0002] Showers are common bathroom products in bathrooms. Traditional showers have relatively simple structures and functions, and usually only have the function of spraying water. Most existing showers are usually composed of a front cover, a rear cover, and a handle, wherein the cavity formed by the front cover and the rear cover being buckled together forms a water storage cavity, and the front cover is provided with multiple nozzles for water discharge, which are gradually contracted from the inside to the outside to pressurize the water flow so that the water flow can be sprayed out. However, since the water storage cavity of these showers is large and stores more water, an inner cavity for storing water will be formed in the nozzle. After the water is turned off, water will continue to emerge from the nozzle under the pressure formed by its own weight, and the water cannot be stopped immediately, or there will always be dripping. This will not only bring a bad experience to users, but also cause the bathroom to remain damp and prone to mold growth, and it will also waste water resources. Summary of the invention

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0028] See Figure 1 and Figure 4 The embodiment of the present invention discloses a quick water-stopping shower head, comprising a rear cover 5, a front cover 4 and a water inlet 2, wherein the rear cover 5 and the front cover 4 are buckled with each other, and the water inlet 2 is provided with a water inlet 21 and a water-dividing chamber 22. After the user opens the water valve, water will enter the chambers of the rear cover 5 and the front cover 4 from the water inlet hole, and the front cover 4 is provided with a water-through hole 41. The water inlet 2 is fixed between the rear cover 5 and the front cover 4, and water can enter the water-dividing chamber 22 from the water inlet 21 and be divided into a plurality of parts in the water-dividing chamber 22, thereby dispersing the water body, thereby reducing the pressure of the water body by dividing it into a plurality of parts, and providing conditions for subsequent quick water-stopping. In order to stop water quickly, the shower head with quick water stop also includes a water stop device 1, which is fixed between the front cover 4 and the rear cover 5. The position of the water stop device 1 corresponds to the position of the water through hole 41. By using the positioning of the water through hole 41, the water stop device 1 can be inserted into the water through hole 41. The water stop device 1 includes an elastic member 11 and a water outlet cavity 12, and the water outlet cavity 12 is used for drainage. The elastic member 11 is arranged between the water diversion cavity 22 and the water outlet cavity 12. The elastic member 11 has elasticity. After the elastic member 11 is deformed, water can enter the water outlet cavity 12 from the water diversion cavity 22. After the elastic member 11 is restored, water can be blocked from entering the water outlet cavity 12 from the water diversion cavity 22. Therefore, by utilizing the characteristics of the elastic member 11, when water is flowing, the water pressure is greater than the restoring force of the elastic member 11, and the elastic member 11 can be pushed to undergo elastic deformation, thereby connecting the water diversion chamber 22 and the water outlet chamber 12, so that water can enter the water outlet chamber 12 from the water diversion chamber 22 and spray out. When the user closes the water valve, due to the sudden drop in water pressure, the water pressure is insufficient to maintain the deformation of the elastic member 11, and the elastic member 11 will return to its original state, thereby closing the channel between the water diversion chamber 22 and the water outlet chamber 12, so that the water flow is immediately cut off, thereby achieving the effect of rapid water stopping.

[0029] The beneficial effects of the embodiments of the present invention are as follows:

[0030] The shower head with quick water stopping in the embodiment of the present invention is provided with a water inlet 2 and a water stopping device 1. The water inlet 2 is provided with a water inlet 21 and a water dividing chamber 22. When the water valve is opened, water enters the water dividing chamber 22 from the water inlet 21. The water dividing chamber 22 divides the water into multiple parts for storage. The water stopping device 1 includes an elastic member 11 and a water outlet chamber 12. Under the action of water pressure, the elastic member 11 will deform, and the water dividing chamber 22 and the water outlet chamber 12 can be interconnected, so that water is sprayed out from the shower head. When the water is turned off, since the water pressure immediately decreases, the water pressure will be lower than the restoring force of the elastic member 11, and the elastic member 11 will return to its original state, so that the water dividing chamber 22 and the water outlet chamber 12 are isolated from each other, and water cannot flow from the water dividing chamber 22 to the water outlet chamber 12, thereby forming a quick water stopping effect. Therefore, the present invention can quickly stop water when the water is turned off, and can prevent the occurrence of continuous dripping.

[0031] The elastic member 11 can be an object made of elastic material, or a mechanism or device with an elastic structure. In order to save costs and facilitate installation, in this embodiment, the elastic member 11 is preferably an object made of silicone material. Specifically, the elastic member 11 includes a water outlet tube 111 and an elastic membrane 112. The water outlet tube 111 can be inserted into the water through hole 41. As a positioning and fixation of the elastic member 11, the two ends of the water outlet tube 111 are respectively provided with an inlet hole 113 and an outlet hole 114. The outlet hole 114 will protrude outward through the front cover 4. The inlet hole 113 is located in the front cover 4. The water outlet chamber 12 is located at the center of the water outlet tube 111 and is connected to the inlet hole 113 and the outlet hole 114. When water is discharged, the water flow will enter the inlet hole 113 from the water diversion chamber 22, and then flow to the outlet hole 114 through the water outlet chamber 12, and finally spray out from the outlet hole 114. In order to increase the pressure of the sprayed water, the cross-sectional area of ​​the inlet hole 113 is larger than the cross-sectional area of ​​the outlet hole 114. The elastic membrane 112 is fixed around the edge of the inlet hole 113, see Figure 2 The elastic membrane 12 can be an integral silicone membrane with continuous edges and extending outwards. This silicone membrane is integrated, has uniform force, and has a good blocking effect. Figure 3 The elastic membrane 12 can also be a sheet-like silicone membrane with its edges cut longitudinally. This silicone membrane is divided into multiple parts and has a better water-permeable effect. The gaps between the parts of the elastic membrane 12 are small enough that water cannot easily overcome the surface tension and enter the gaps. Therefore, the elastic membrane 12 still has the effect of blocking water from entering the inlet hole 113.

[0032] When the elastic membrane 112 does not undergo elastic deformation, it can block water laterally at the side of the inlet hole 113, thereby blocking the communication between the water diversion chamber 22 and the inlet hole 113. When the valve is opened, under the action of water pressure, water will break through the blocking of the elastic membrane 112, thereby connecting the water diversion chamber 22 and the inlet hole 113, and water can be sprayed out from the outlet hole 114. When the water is turned off, due to the reduction and disappearance of the water pressure, the elastic membrane 112 will return to its original state under the action of elastic force and block the water flow again, so that it stays at the side of the inlet hole 113, and the water can be ejected from the outlet hole 114. Due to the loss of water supply, the water outlet tube 111 will immediately stop discharging water. Since the water is blocked at the side of the inlet hole 113, the gravity direction of the water is perpendicular to the elastic direction of the elastic membrane 112, and the gravity of the water cannot affect the deformation of the elastic membrane 112. Therefore, the effect of rapid water stopping can be achieved. Moreover, the water that loses power will remain on the side of the elastic membrane 112 instead of the upper part. Therefore, the gravity of the water will not affect the closing effect of the elastic membrane 112, thereby further enhancing the effectiveness of the use of the elastic membrane 112 and achieving a faster water stopping effect.

[0033] In order to fix the elastic member 11, the water-stopping device 1 also includes a mounting plate 13. There are multiple elastic members 11, and the number of the elastic members 11 corresponds to the number of the water holes 41. The multiple elastic members 11 are fixed on the mounting plate 13. The mounting plate 13 connects all the elastic members 11 transversely. The elastic membrane 112 protrudes from the plane of the mounting plate 13, so that the water can be blocked transversely at the edge of the inlet hole 113. The water outlet cavity 12 runs through the mounting plate 13. In order to facilitate installation and save production costs, the mounting plate 13 is integrated with the multiple elastic members 11. The mounting plate 13 can be a pad made of silicone like the elastic members 11, so that the surface friction of the mounting plate 13 is increased, which can make the installation of the mounting plate 13 more secure and also play a good waterproof role.

[0034] See also Figure 5 and Figure 6The elastic membrane 112 gradually expands outward from the plane of the mounting plate 13 toward the direction away from the outlet hole 114, and the longitudinal cross-section of the elastic membrane 112 is in the shape of an "inverted eight" with a wide top and a narrow bottom. The water stop device 1 also includes a gland 14, and the gland 14 is provided with a cut-off groove 141. The notch of the cut-off groove 141 faces the inlet hole 113. The gland 14 can surround a part of the elastic membrane 112. Since the elastic membrane 112 gradually expands outward toward the direction away from the outlet hole 114, the side edge of the elastic membrane 112 can abut against the inner side wall of the cut-off groove 141. The cut-off groove 141 and the elastic membrane 112 constitute the second "on / off valve" of the water flow passage. When water enters from the outside of the cut-off groove 141, under the action of water pressure, the side edge of the elastic membrane 112 can undergo transverse elastic contraction toward the inside of the cut-off groove 141 and move away from the inner wall of the cut-off groove 141, and a gap is generated between the elastic membrane 112 and the inner wall of the cut-off groove 141, through which water can enter the inlet hole 113. When the water supply is stopped, the side edge of the elastic membrane 112 will return to its original shape toward the side wall of the cut-off groove 141. When the elastic membrane 112 abuts against the inner wall of the cut-off groove 141, the water flow passage is cut off, and water can no longer be sprayed out from the water outlet cylinder 111.

[0035] By utilizing the cooperation between the pressure cover 14 and the elastic member 11, the water flow can be turned on and off. Therefore, the embodiment of the present invention has the advantage of simple structure. The elastic member 11 and the mounting plate 13 are integrated. The positions of the elastic member 11 and the water hole 41 correspond to each other. During installation, the water hole 41 can be directly used for positioning. The mounting plate 13 and the elastic member 11 are installed between the front cover 4 and the rear cover 5. Therefore, the present invention is easy to install and simple to use.

[0036] A water inlet gap 15 is left between the end of the pressure cover 14 and the mounting plate 13. When water is flowing, water can enter the inner wall of the cut-off groove 141 through the water inlet gap 15 and elastically push the side edge of the elastic membrane 112. When the water is stopped, the water will be blocked in the water inlet gap 15. The quick water-stop shower head also includes a pressure plate 3. The pressure cover 14 is fixed to a side of the pressure plate 3 close to the elastic membrane 112. A water storage chamber 31 is provided in the pressure plate 3. The water storage chamber 31 is provided between the pressure plate 3 and the mounting plate 13. The elastic membrane 112 is located in the water storage chamber 31. When the water supply is cut off, the water that cannot be discharged from the water outlet tube 111 will remain in the water storage chamber 31. Since the pressure cover 14 and the elastic membrane 112 are distributed in the water storage chamber 31, the water will stay on the side of the elastic membrane 112 instead of on the elastic membrane 112. Therefore, the gravity of the water has no effect on the elastic membrane 112, thereby avoiding the situation where the gravity of the water is too large to break the elastic membrane 112. The pressure plate 3 is provided with a water storage hole 32, and the water diversion chamber 22 is connected to the water storage chamber 31 through the water storage hole 32. The water diversion chamber 22 can divert water to multiple chambers.

[0037] See also Figure 8 When water is discharged, water will first enter the water diversion chamber 22 from the water inlet 21. Under the water diversion effect of the water diversion chamber 22, the water will be divided into multiple parts and enter the water storage chamber 31 through the water storage hole 32. Under the action of water pressure, the water will push the elastic membrane 112 in the water inlet gap 15 to leave the inner wall of the cut-off groove 141, and enter the inlet hole 113 and the water outlet chamber 12 in turn, and finally spray out from the outlet hole 114; see Figure 7 When the water is cut off, the elastic membrane 112 will press against the inner wall of the cut-off groove 141 under the elastic effect, and the water will stay in the water storage chamber 31. The water diversion chamber 22 can disperse the impact force of the water flow, so that the elastic membrane 112 can be reset faster when the water loses water pressure, thereby further accelerating the speed of closing the channel.

[0038] The above are preferred embodiments of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
