Description

Technical Field

[0001] The invention belongs to the field of bathroom products, and in particular relates to a shower head. Background Art

[0002] Showers are daily bathroom products. There are many types of showers available. One type of shower is called a pressurized shower, but the pressurization methods are different. Some showers achieve higher water pressure by reducing the flow rate, which is effective in terms of water saving, but the user experience will be worse if the flow rate is small. Another type of shower basically requires an external power device to provide greater pressure, which is disadvantageous in terms of energy consumption and structural cost. Some hotels use larger water pipes to obtain sufficient pressure and flow, but the size of the pipes in most renovated houses is immutable. Therefore, obtaining a higher water pressure will reduce the flow rate. For some people, a smaller flow rate will extend the use time, which not only has a poor user experience, but may not have a good water saving effect.

[0003] The utility model patent with the Chinese authorized patent announcement number "CN220547109U" and the patent name "A pressurized shower head" discloses a pressurized structure for a shower head. It can be seen from the patent text that in the absence of other external structures, it is obvious that pressurization requires further increasing the resistance of the water flow. According to the dynamic pressure formula, the smaller the flow rate, the greater the static pressure. The static pressure can be increased by reducing the flow rate under the same cross-section. If the cross-sectional area of ​​the flow can be changed, the static pressure can be increased by reducing the cross-sectional area. At this time, the dynamic pressure is increasing, that is, the speed of the shower water is increased under the premise of reducing the flow rate. Therefore, the user will feel that the pressure has increased, which is actually obtained by sacrificing the flow rate. In particular, in some areas with low tap water pressure, the experience of using such a shower head will be very poor, that is, the pressurization effect is not obvious but the flow rate is greatly reduced.

[0004] The invention patent with the Chinese authorized patent announcement number "CN102649105B" and the patent name "An Air Injection Pressurized Portable Shower" discloses the use of injected air to increase the pressure of the shower. There is a large amount of gas in the shower. For some people, the user experience is poor due to the large amount of gas mixed in the water flow, and it does not achieve high-quality and efficient increase in the water pressure in the shower.

[0005] The Chinese authorized patent announcement number is "CN118060094A" and the patent name is "Multi-function Shower". The invention patent discloses a shower with adjustable flow. The shower is equipped with multiple operating mechanisms and has a relatively complex structure, but it cannot meet the needs of different designs, such as allowing the shower water chamber to have a water storage function. Summary of the invention

[0006] In view of the above-mentioned prior art, an object of the present invention is to provide a pressurized shower head which is more comfortable to use or more water-saving.

[0007] The technical solution of the present invention is implemented as follows: a shower head includes an energy storage part, a water storage part, a water spraying part and a control part. The energy storage part is provided with a mechanical energy storage structure to store gravitational potential energy by changing the height of a counterweight block or to change the shape of an elastic structure to store elastic potential energy. The water storage part is provided with a water storage chamber, which is connected to a water inlet pipe. A control part is arranged between the water storage part and the water spraying part, or the water spraying part and the control part are an integrated structure so that the water flow rate of the water spraying part is controlled by the control part. The water storage part is made of a piston structure or an elastic material so that the volume of the water storage chamber can change within a certain range and when the volume of the water storage chamber increases, the mechanical energy storage structure can be pushed to move or deform to achieve potential energy storage.

[0008] The beneficial effect of such a design is that: since the volume can be changed, after the control valve of the water inlet pipe is opened, the volume of the water storage chamber becomes larger under the action of water pressure and squeezes or moves the mechanical energy storage structure to realize energy storage, that is, the height of the counterweight block rises or the shape of the elastic structure changes. After the energy storage is completed, the shower can be used, that is, the control part is opened to connect the water spray part with the water storage chamber, the shower can discharge water, and the water inlet pipe can continue to take in water, but at this time the volume of the water storage chamber begins to decrease and the energy storage part begins to release energy, that is, the counterweight block begins to descend or the elastic structure recovers its shape, so that the water discharge speed of the shower is faster or the flow rate is larger. On the one hand, a larger flow rate can obtain a better bathing experience, especially in places where the water pressure is insufficient or the water pipe is thin, the flow rate is relatively small, and the technical solution of the present invention can solve this technical problem; on the other hand, under the same flow rate, a faster water discharge speed can be obtained to achieve a better cleaning effect and realize the purpose of water saving. Of course, a smaller flow rate can also be used to achieve a similar cleaning effect and realize the function of water saving.

[0009] Furthermore, the energy storage part includes a spring, one end of the spring is directly or indirectly connected to the water storage part, and the other end is fixed at a determined position without moving, so that when the volume of the water storage chamber increases, the spring can be squeezed to store elastic potential energy. The spring design has a simple structure, and air springs, rubber springs, etc. can also be used. These components are easy to purchase and low cost.

[0010] Furthermore, the energy storage part includes an airbag or a cylinder, one end of the airbag or the cylinder is in contact with the water storage part, and the other end is fixed at a determined position without moving, so that when the volume of the water storage chamber increases, the airbag or the cylinder can be squeezed to compress the gas in the airbag or the cylinder to store energy. The airbag or the cylinder can adjust the force by adjusting the air pressure, so it can have a larger range of application, that is, different air pressures can be adjusted to achieve different energy storage efficiencies in different water pressure areas. The air pressure can be adjusted accordingly in areas with higher water pressure. Of course, it will basically not work if the air pressure is higher than the water pressure, and the air pressure will also increase during the change of the water storage chamber volume, requiring a certain floating space. The airbag or cylinder has a smaller mass than other structures and is more convenient to install.

[0011] Furthermore, the energy storage part includes a counterweight block, which is arranged above the water storage part so that when the volume of the water storage chamber increases, it can push the counterweight block to move upward to store gravitational potential energy. The use of the counterweight block has a more stable energy storage effect, that is, it has the same output force within the displacement range, and has a long service life, basically no loss, and will not age.

[0012] Furthermore, the water storage part includes a piston plate and a water storage pipe. A control part is arranged at the lower end of the water storage pipe or is connected to the control part through a pipeline. The piston plate is located in the water storage pipe and can move relative to the water storage pipe under the action of water pressure when the valve of the water inlet pipe is opened.

[0013] Furthermore, the water storage part includes an elastic water bag, which is made of elastic material. The elastic water bag is connected to the water inlet pipe, and the elastic water bag is directly or indirectly connected to the control part. In this way, the air bag can be made of elastic rubber material, which has a simple structure, low cost, easy installation, and can meet the requirements of domestic water pressure.

[0014] Furthermore, the water storage part includes a retractable elastic bellows, a sealing plate is provided at the upper end of the elastic bellows, a control part is provided at the lower end of the elastic bellows or is connected to the control part through a pipeline, the elastic bellows is connected to the water inlet pipe and when the valve of the water inlet pipe is opened, the sealing plate can drive the mechanical energy storage structure to move or deform under the action of water pressure. The bellows can be made of plastic material or metal material, especially metal material has high strength and long service life, and can also be made of rubber material, both of which can allow the water storage chamber to achieve volume changes within a certain range.

[0015] Furthermore, the water spray part and the control part are an integrated structure and are installed at the lower end of the water storage part. The lower end of the water storage part is provided with an annular plate, a circular plate, an inner tube and an outer tube. The lower end of the inner tube and the lower end of the outer tube are connected by the annular plate, and the upper end surface of the inner tube is closed by the circular plate. The tube wall of the inner tube is provided with at least one through hole. The water spray part and the control part include an annular valve tube and a spray cover plate. The spray cover plate is provided with an inner cavity. The annular valve tube is provided with at least one water guide hole, which is connected to the inner cavity provided in the spray cover plate. The annular valve tube is installed on the inner side of the tube wall in a rotatable manner relative to the inner tube so that rotating the annular valve tube can switch the connection state between the inner cavity and the water storage cavity. Such a design can make full use of the space of the shower head and use the shower head to store water. The water flow can be directly controlled by the shower head. In this way, the shower head and the bathroom ceiling can be integrated together, so that the bathroom has a larger utilization space. Most of the structure of the shower head is hidden behind the ceiling, and the bathroom as a whole is more concise.

[0016] Furthermore, the annular valve tube is fixed on the spray cover plate or adopts an integrated structure with the spray cover plate so that the annular valve tube can be rotated by rotating the spray cover plate. The spray cover plate is installed on the outside of the outer tube in a manner that it can rotate relative to the outer tube. This design structure is simple and easy to control, that is, the water flow can be controlled by rotating the spray cover plate.

[0017] Furthermore, a control ring is provided at the lower end of the spray cover plate, and the control ring is arranged to protrude relative to the spray cover plate, which makes it more convenient to control the spray cover plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As required, detailed embodiments of the present invention are disclosed herein, but it should be understood that the disclosed embodiments are merely exemplary of the present invention, and the present invention may be implemented in different and alternative forms. The accompanying drawings may not be drawn to scale, and certain features may be exaggerated or reduced to show the details of specific components. Therefore, the specific structural and functional details disclosed herein should not be understood as having a limiting meaning, but only as a representative basis to teach those skilled in the art to adopt the present invention differently. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a shower head comprises an energy storage part 1, a water storage part 2, a water spraying part 3 and a control part 4. The energy storage part 1 is provided with a mechanical energy storage structure 10 for storing elastic potential energy by changing the shape of the elastic structure. The water storage part 2 is provided with a water storage chamber 20, which is connected to a water inlet pipe 21. The water spraying part 3 and the control part 4 are an integrated structure so that the water flow of the water spraying part 3 is controlled by the control part 4. The water storage part 2 is made of elastic material so that the volume of the water storage chamber 20 can change within a certain range and when the volume of the water storage chamber 20 increases, the mechanical energy storage structure 10 can be pushed to move or deform to achieve potential energy storage.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the shower head is also provided with a tubular housing 5, which can be a square tube or a round tube as appropriate. A flange 51 is provided at the upper end of the housing 5 and can be fixed to the ceiling by screws 52. Preferably, the distance between the flange 51 and the housing 5 can be adjusted so that the flange 51 can fix the housing 5 to different heights. The flange 51 can also be indirectly installed on the ceiling through an extension pipe. A mounting hole can also be provided on the side of the housing 5 to mount the housing 5 on the wall. The shower head of the present invention is heavier than that of an ordinary shower head. If a fixed installation method is not adopted, a separate bracket structure can also be provided to support the shower head, but the cost is high and it occupies a large space. Preferably, the shower head is installed on the bathroom ceiling. If a square ceiling board is used, a ceiling mounting board 53 with holes can be matched and provided. In this way, the installation is more beautiful. The installation height of the shower head can be determined according to the situation and is not necessarily flush with the ceiling. Generally, the height of the shower head from the ground has a certain relationship with the height of the user, that is, the height of the shower head is adjusted according to the height.

[0033] like Figure 4 , Figure 5 and Figure 6 As shown, the energy storage part 1 includes a spring 11, one end of the spring 11 is directly or indirectly in contact with the water storage part 2, and the other end is fixed at a certain position without moving, so that when the volume of the water storage chamber 20 increases, the spring 11 can be squeezed to store elastic potential energy. Figure 6 The upper end position of the middle spring 11 can be adjusted according to the needs of water pressure, such as adjusting it through a screw rod, or adding some pads to support the spring 11. After adjustment, the position of the spring 11 can be kept unchanged, or different types of springs 11 can be equipped. Different springs 11 are selected for different water pressure requirements. In this way, the cost will be relatively high. The spring 11 can be an air spring, a rubber spring or a metal spring. All types of springs have the same energy storage function. The selection of the spring 11 model can be obtained according to F=PS, that is, the elastic force is equal to the product of the pressure and the area. Of course, there must be a certain margin, that is, when the water storage chamber 20 is at its maximum, that is, when the spring 11 is compressed to the bottom, the elastic force is less than or equal to the product of the tap water pressure and the area of ​​the cross section of the water storage chamber 20. Preferably, a spring frame 12 is provided between the energy storage part 1 and the water storage part 2, and a guide tube 13 is provided at the center of the spring frame 12. A water pipe groove 14 can be provided below the spring frame 12 to accommodate the water inlet pipe 21 to prevent the water inlet pipe 21 from being squeezed.

[0034] like Figure 4 , Figure 5 and Figure 7 As shown, the water storage part 2 includes a retractable elastic bellows 15, a sealing plate 16 is provided at the upper end of the elastic bellows 15, and a control part 4 is provided at the lower end of the elastic bellows 15. The elastic bellows 15 is connected to the water inlet pipe 21 and when the valve of the water inlet pipe 21 is opened, the sealing plate 16 can drive the mechanical energy storage structure 10, i.e., the spring 11, to deform under the action of water pressure. Figure 4As shown, the spring 11 is in a compressed state, and the water storage chamber 20 has a larger volume. Figure 5 As shown, the spring 11 is partially released, and the volume of the water storage chamber 20 becomes smaller. To ensure the pressurization effect, even if the water storage chamber 20 is at the minimum volume position, the spring 11 still has a certain amount of compression, which can ensure that the spring 11 has a good energy storage effect. The water inlet pipe 21 is set at the upper end of the water storage chamber 20 and needs to move with the water storage chamber 20. Therefore, a long pipe groove 54 needs to be set on the side wall of the shell 5 to ensure the movement of the water inlet pipe 21. The water inlet pipe 21 is set at the center position, and the pressure is more balanced to avoid the situation where the water output on one side of the shower is larger.

[0035] like Figure 4 , Figure 5 and Figure 8 As shown, the water spray part 3 and the control part 4 are an integral structure and are installed at the lower end of the water storage part 2. The lower end of the water storage part 2 is provided with an annular plate 22, a circular plate 23, an inner tube 24 and an outer tube 25. The lower end of the inner tube 24 and the lower end of the outer tube 25 are connected by the annular plate 22, and the upper end surface of the inner tube 24 is closed by the circular plate 23. The tube wall 27 of the inner tube 24 is provided with at least one through hole 26. The water spray part 3 and the control part 4 include an annular valve tube 40 and a spray cover plate 30. The spray cover plate 30 is provided with an inner cavity 32. The annular valve tube 40 is provided with at least one water guide hole 41. The water guide hole 41 is connected to the inner cavity 32 provided in the spray cover plate 30. The annular valve tube 40 is installed on the inner side of the tube wall 27 in a rotatable manner relative to the inner tube 24 so that rotating the annular valve tube 40 can switch the connection state between the inner cavity 32 and the water storage cavity 20.

[0036] like Figure 4 , Figure 5 and Figure 8As shown, the annular valve tube 40 can be manufactured separately and fixed on the spray cover plate 30 or adopt an integral structure with the spray cover plate 30 so that the annular valve tube 40 can be rotated by rotating the spray cover plate 30, and the spray cover plate 30 is installed on the outside of the outer tube 25 in a manner that it can rotate relative to the outer tube 25. A control ring 31 is provided at the lower end of the spray cover plate 30, and the control ring 31 is protruded relative to the spray cover plate 30. The spray cover plate 30 is provided with at least two groups of inner cavities 32, namely a large hole water outlet cavity 33 and a small hole water outlet cavity 34. The large hole water outlet cavity 33 and the small hole water outlet cavity 34 are evenly distributed circumferentially. A central water outlet cavity 39 can also be provided at the center position of the spray cover plate 30 and is connected with the large hole water outlet cavity 33 and the small hole water outlet cavity 34. The large hole water outlet cavity 33 is provided with a large inner water cavity 35 and a large outer water cavity 36, and the large inner water cavity 35 and the large outer water cavity 36 are connected through a large bottom hole 55. The small hole water outlet cavity 34 is provided with a small inner water cavity 38 and a small outer water cavity 37, and the small inner water cavity 38 and the small outer water cavity 37 are connected through a small bottom hole 56. The annular valve tube 40 is provided with a large water guide hole 42 and a small water guide hole 43. The large water guide hole 42 is connected to the large hole water outlet chamber 33, and the small water guide hole 43 is connected to the small hole water outlet chamber 34. The positions of the large water guide hole 42 and the small water guide hole 43 can be controlled by rotating the annular valve tube 40. The large water guide hole 42 or the small water guide hole 43 can be connected to the through hole 26 as needed. The large water guide hole 42 and the small water guide hole 43 are not connected to the through hole 26, that is, they are in a closed state. Of course, more water guide holes 41 and inner chambers 32 can be set as needed, but a similar structural design can be adopted. As a preferred embodiment, the water storage part 2 is provided with a temperature sensor to detect the water temperature of the water storage chamber 20, so that the temperature of the water storage part 2 can be displayed, and the water temperature of the water inlet pipe 21 can be adjusted in time according to the temperature conditions to obtain a more comfortable spraying experience. When using the shower, first open the valve of the water inlet pipe 21, close the control unit 4, and let the water storage unit 2 start to store water. When the water storage chamber 20 expands to the maximum range, the water pressure in the water storage chamber 20 is the same as the water pressure in the water inlet pipe 21. When the temperature is suitable, you can start showering. Just open the control unit 4, that is, turn the control ring 31 so that the through hole 26 is aligned with the water guide hole 41 to discharge water. After use, directly close the valve of the water inlet pipe 21. Of course, if it is closed for a short time, the control ring 31 can be used to close it. In addition, if the water pressure drops, the control unit 4 can be temporarily closed to store energy. After all, the volume of the water storage chamber 20 is limited.

[0037] The shower head can be provided with two water inlet pipes 21, that is, cold water and hot water enter the shower head together and then mix, which not only makes the water pressure higher when flowing quickly, but also reduces the cost of using a single-way valve.

[0038] Embodiment 2:

[0039] like Fig. 9As shown, a shower head comprises an energy storage part 1, a water storage part 2, a water spray part 3 and a control part 4. The energy storage part 1 is provided with a mechanical energy storage structure 10 for storing elastic potential energy by changing the shape of the elastic structure. The water storage part 2 is provided with a water storage chamber 20, which is communicated with a water inlet pipe 21. The control part 4 is arranged between the water storage part 2 and the water spray part 3, or the water spray part 3 and the control part 4 are an integrated structure so that the water flow of the water spray part 3 is controlled by the control part 4. The water storage part 2 adopts a piston structure so that the volume of the water storage chamber 20 can change within a certain range and when the volume of the water storage chamber 20 increases, the mechanical energy storage structure 10 can be pushed to move or deform to realize the storage of potential energy.

[0040] like Fig. 9 As shown, the energy storage part 1 includes a cylinder 17, one end of which is in contact with the water storage part 2 and the other end is fixed at a certain position without moving, so that when the volume of the water storage chamber 20 increases, the cylinder 17 can be squeezed to compress the airbag or the gas in the cylinder 17 to store energy.

[0041] like Fig. 9 As shown, the water storage part 2 includes a piston plate 28 and a water storage pipe 29. The control part 4 is arranged at the lower end of the water storage pipe 29 or connected to the control part 4 through a pipeline. The piston plate 28 is located in the water storage pipe 29 and can move relative to the water storage pipe 29 under the action of water pressure when the valve of the water inlet pipe 21 is opened. The control part 4 can be an ordinary water valve.

[0042] like Fig. 9 As shown, the energy storage part 1 and the water storage part 2 adopt an integrated structure and use the same piston plate 28. A plurality of sealing rings 80 can be arranged on the piston plate 28. The cylinder 17 can be provided with an air pipe 71 and the air pressure in the cylinder 17 can be adjusted through the air pipe. Of course, the air pressure in the cylinder 17 is less than the water pressure in the water inlet pipe 21. In this way, when the valve of the water inlet pipe 21 is opened, water flows into the water storage chamber 20. The volume of the water storage chamber 20 increases, so that the piston plate 28 moves toward one end of the cylinder 17 to compress the cylinder 17 to store energy. When the control part 4 is opened, the cylinder 17 pushes the piston plate 28 to squeeze the water storage chamber 20 so that the water spray part 3 has a larger water flow rate. If the tap water pressure is about 0.14MPa, the air pressure of the cylinder 17 can be controlled at about 0.1MPa. In this way, the volume of the cylinder 17 can be changed within 40%, and a better pressurization effect can be obtained. For areas with higher tap water pressure, the air pressure in the cylinder 17 can be appropriately increased. From the perspective of water conservation, the greater the pressure of the cylinder 17, the better, but it certainly cannot exceed the water pressure. The cylinder 17 can also be replaced by an air bag, which has the same function.

[0043] Embodiment 3:

[0044] like Fig.10As shown, a shower head comprises an energy storage part 1, a water storage part 2, a water spray part 3 and a control part 4. The energy storage part 1 is provided with a mechanical energy storage structure 10 for storing gravitational potential energy by changing the height of a counterweight block 18. The water storage part 2 is provided with a water storage chamber 20, which is communicated with a water inlet pipe 21. The control part 4 is arranged between the water storage part 2 and the water spray part 3, or the water spray part 3 and the control part 4 are an integrated structure so that the water flow of the water spray part 3 is controlled by the control part 4. The water storage part 2 is made of elastic material so that the volume of the water storage chamber 20 can change within a certain range and when the volume of the water storage chamber 20 increases, the mechanical energy storage structure 10 can be pushed to move or deform to realize the storage of potential energy.

[0045] like Fig.10 As shown, the energy storage part 1 includes a counterweight 18, which is arranged above the water storage part 2 so that when the volume of the water storage chamber 20 increases, the counterweight 18 can be pushed upward to store gravitational potential energy. Generally, the tap water pressure is about 0.14MPa, but the water pressure in some areas with lower water pressure may be below 0.08MPa. At this time, it does not require too much pressure to have a significant boosting effect. If the boosting of the energy storage structure is controlled at about 0.04MPa, the cross section of the counterweight 18 is the same as the cross section of the water storage part 2, and it is made of iron material. The height is controlled within 0.5 meters to meet the requirements. If the cross-sectional area of ​​the counterweight 18 is larger than the cross-sectional area of ​​the water storage part 2, or a material with a higher density such as lead is used, the height of the counterweight 18 can be further reduced. In order to reduce costs, concrete or sand and gravel with water can also be used, but the volume is relatively large, and for sand and gravel, a container of a certain strength is also required to maintain the shape. The greater the flow rate, the faster the water flow speed, the smaller the static pressure of the water storage chamber 20, and the more obvious the pressurization effect of the counterweight block 18. When the flow rate is very small, the static pressure is relatively large. If this situation is considered, the mass of the counterweight block 18 needs to be further increased to obtain the pressurization effect.

[0046] like Fig.10 As shown, the water storage part 2 includes an elastic water bag 19, which is made of elastic material such as rubber material. As a preferred embodiment, a heat-insulating material can be provided on the outside to prevent the elastic water bag 19 from being worn and to have a heat-insulating effect. The lower end of the elastic water bag 19 is connected to the control part 4 through a pipeline, and the control part 4 controls the water flow of the water spraying part 3. The elastic water bag 19 is connected to the water inlet pipe 21 and when the valve of the water inlet pipe 21 is opened, the elastic water bag 19 can drive the mechanical energy storage structure 10, i.e., the counterweight 18 to move under the action of water pressure. The water inlet pipe 21 needs to be a hose for easy movement.
