Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a negative pressure instant-on / off shower device. Background Art

[0002] When the water in the shower is turned off, the residual water inside it will continue to flow out along the water outlet or continue to drip for a period of time, resulting in a bad user experience. For this reason, there are stop-and-turn structures on the market that can solve the above problems, and these structures often adopt a blocking method. When the water is turned on, the movable panel is driven away from the water outlet panel by hydraulic force, so that the water outlet is opened. After the water is turned off, the residual water inside the shower is automatically squeezed out and the water outlet is blocked by resetting the movable panel to prevent it from continuing to discharge water. When the above structure is in use, there is a process of squeezing the residual water when turning off the water, resulting in the structure still failing to achieve the stop effect. For this reason, the present application proposes another negative pressure stop-and-turn shower device that can solve the above problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a structure which can truly shut down and stop when it fails.

[0004] A negative pressure shower device that stops and starts immediately includes a water inlet channel, a water outlet, a water passage cavity, a negative pressure cavity and a hydraulic drive component, wherein:

[0005] The water inlet channel and the water outlet are connected through a water passage cavity, and the negative pressure cavity is connected to the water passage cavity.

[0006] The hydraulic drive assembly is installed close to the water inlet channel and is driven by the water in the water inlet channel, forcing the negative pressure chamber to shrink. When the water in the water inlet channel is turned off, the hydraulic drive assembly releases the negative pressure chamber, which is restored and causes the water flow chamber to form a negative pressure. The residual water in the water flow chamber is adsorbed inside the shower head under the negative pressure.

[0007] The utility model provides a negative pressure chamber connected to the water chamber in the shower head, which can shrink when water is inletted, and restore when the water is turned off to form a negative pressure in the water chamber, thereby absorbing the residual water in the water chamber and preventing the residual water from being continuously or gradually discharged from the water outlet. Since the negative pressure chamber proposed in the present application can be restored in time at the moment of turning off the water, the effect of stopping the water when the water is turned off can be truly achieved.

[0008] Preferably, the shower head is provided with an inner frame and a water outlet panel, the inner frame and the water outlet panel are arranged at intervals to form the water passage cavity. The negative pressure cavity is arranged on the inner frame, and the water outlet nozzle is arranged on the water outlet panel.

[0009] Preferably, the negative pressure chamber includes a fixed shell, a movable head and a first spring. The fixed shell is installed on the inner frame, and one end of the internal space is connected to the water flow chamber, and the other end is provided with an opening. The movable head and the fixed shell are mounted on each other and movably assembled. When water is discharged, the movable head is pressed by the hydraulic drive assembly to press the movable head into the fixed shell to achieve compression of the negative pressure chamber. When the water is turned off, the first spring provides a relative elastic force for the fixed shell and the movable head to be pulled apart, thereby allowing the negative pressure chamber to be restored. The recovery process will cause negative pressure to form inside the water flow chamber.

[0010] Preferably, the movable head is telescopically installed in the fixed shell through the opening, and a sealing ring is provided between the periphery of the movable head and the inner wall of the fixed shell to improve the airtightness of the negative pressure chamber and the water passage chamber to avoid the failure of the negative pressure effect. The first spring is compressed, and one end of the first spring is against the movable head, and the other end is against the inner frame or the water outlet panel.

[0011] Preferably, the outer part of the movable head is stepped, and the opening of the fixed shell is a constriction that limits the movable head from being completely separated. The movable head is provided with a receiving groove that communicates with the internal space of the fixed shell, and the water outlet panel is provided with a limiting protrusion toward the receiving groove. One end of the first spring is sleeved on the limiting protrusion, and the other end is inserted into the receiving groove to prevent the first spring from being offset during use. At the same time, by providing the receiving cavity groove, the volume of the negative pressure cavity can be increased, and the change amount of the compression state and the recovery state can be further increased to provide a greater negative pressure effect.

[0012] Preferably, the hydraulic drive assembly uses a lever structure to press the negative pressure chamber, and the structure is simple and reliable.

[0013] Preferably, the hydraulic drive assembly includes a hydraulic drive member, a second spring, a connecting rod and a pressure rod. The hydraulic drive member is movably installed at the connecting position between the water inlet channel and the water passage chamber, and the second spring provides the hydraulic drive member with elastic force to support and block the water outlet of the water inlet channel. The connecting rod and the pressure rod are both swingably installed inside the shower head, one end of the connecting rod is connected to the hydraulic drive member, and the other end is connected to the pressure rod. The other end of the pressure rod is against the negative pressure chamber. When the shower head is filled with water, the hydraulic force pushes the hydraulic drive member away from the water outlet of the water inlet channel, and at the same time drives the pressure rod through the connecting rod. The end of the pressure rod can press the negative pressure chamber to force it to shrink. When the water is turned off, the hydraulic drive member is reset under the action of the second spring, and drives the pressure rod through the connecting rod, so that the end of the pressure rod releases the negative pressure chamber, so that the negative pressure chamber can be restored to generate negative pressure.

[0014] Preferably, a partition is provided at the end of the water inlet channel, a guide hole is provided in the middle of the partition, and the water outlet is provided around the guide hole. A guide column is provided at one end of the hydraulic drive member to be telescopically inserted into the guide hole to improve the directional accuracy of the hydraulic drive member when moving, and a mounting groove for accommodating the second spring is provided at the other end of the hydraulic drive member to prevent the second spring from being separated from the working position when in use.

[0015] Preferably, a ball head is provided in the middle of the connecting rod, and the ball head is swung and installed in the swing groove outside the water passage cavity, and the swing is flexible. A clearance hole for one end of the connecting rod to pass through is provided at the bottom of the swing groove, and a sealing ring is provided between the ball head and the swing groove, which can improve the air tightness of the water passage cavity.

[0016] Preferably, there are at least two negative pressure chambers, which are arranged around the hydraulic drive assembly, so as to provide a reliable negative pressure effect for the water passage chamber.

[0017] From the above description of the utility model, it can be seen that the utility model has the following beneficial effects:

[0018] By setting a negative pressure chamber connected to the water chamber in the shower head, it can shrink when water is flowing in, and when the water is turned off, it can restore to form a negative pressure in the water chamber, so that the residual water in the water chamber can be absorbed to prevent the residual water from being continuously or gradually discharged from the water outlet.

[0019] Since the negative pressure chamber proposed in the present application can be restored in time when the water is turned off, the effect of stopping the water when the water is turned off can be truly achieved;

[0020] By arranging a receiving cavity groove in the movable head of the negative pressure cavity, the volume of the negative pressure cavity can be increased, and the change amount between the compression state and the recovery state can be further increased to provide a greater negative pressure effect.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0031] See also Figures 1 to 6 A negative pressure shower device that stops and starts immediately includes a water inlet channel 1, a water outlet 2, a water passage chamber 3, a negative pressure chamber 4 and a hydraulic drive assembly 5, wherein:

[0032] The water inlet channel 1 and the water outlet 2 are connected through the water passage chamber 3, and the negative pressure chamber 4 is connected to the water passage chamber 3. The hydraulic drive assembly 5 is installed close to the water inlet channel 1, and is driven by the water inlet in the water inlet channel 1, and forces the negative pressure chamber 4 to shrink. When the water inlet channel 1 is turned off, the hydraulic drive assembly 5 releases the negative pressure chamber 4, and the negative pressure chamber 4 is restored and causes the water passage chamber 3 to form a negative pressure. The residual water in the water passage chamber 3 is adsorbed inside the shower head under the action of the negative pressure. In one embodiment, there are at least two negative pressure chambers 4, and they are arranged around the hydraulic drive assembly 5, so as to provide a reliable negative pressure effect for the water passage chamber 3.

[0033] In this embodiment, the shower head is provided with an inner frame 6 and a water outlet panel 7, which are arranged at intervals to form the water passage cavity 3. The negative pressure cavity 4 is arranged on the inner frame 6, and the water outlet nozzle 2 is arranged on the water outlet panel 7.

[0034] On the basis of the above embodiments, in one embodiment, the negative pressure chamber 4 includes a fixed shell 41, a movable head 42 and a first spring 43. The fixed shell 41 is installed on the inner frame 6 (in this embodiment, the fixed shell 41 and the inner frame 6 are integrally formed), and one end of the internal space is connected to the water flow chamber 3, and the other end is provided with an opening. The movable head 42 and the fixed shell 41 are mutually sleeved and movably assembled. When water is discharged, the movable head 42 is pressed by the hydraulic drive component 5 to press the movable head 42 into the fixed shell 41 to compress the negative pressure chamber 4. When the water is turned off, the first spring 43 provides a relative pulling elastic force for the fixed shell 41 and the movable head 42 to be pulled apart, so that the negative pressure chamber 4 can be restored. The recovery process will cause negative pressure to be formed inside the water flow chamber 3.

[0035] Optionally, the movable head 42 is installed in the fixed shell 41 through the opening telescopically, and a sealing ring 8 is provided between the periphery of the movable head 42 and the inner wall of the fixed shell 41 to improve the airtightness of the negative pressure chamber 4 and the water passage chamber 3 to avoid the failure of the negative pressure effect. The first spring 43 is compressed, and one end of the movable head 42 is supported by the movable head 42, and the other end is supported by the inner frame 6 or the water outlet panel 7. In addition, in other embodiments, the outer part of the movable head 42 is stepped, and the opening of the fixed shell 41 is a constriction that limits the complete separation of the movable head 42. The movable head 42 is provided with a receiving groove connected to the internal space of the fixed shell 41, and the water outlet panel 7 is provided with a limiting protrusion toward the receiving groove. One end of the first spring 43 is sleeved on the limiting protrusion, and the other end is inserted into the receiving groove to avoid the first spring 43 from deflecting when in use. At the same time, by setting the receiving cavity groove, the volume of the negative pressure chamber 4 can be increased, and the change amount of the compression state and the recovery state can be further increased to provide a greater negative pressure effect.

[0036] In one embodiment, the hydraulic drive assembly 5 uses a lever structure to press the negative pressure chamber 4, and the structure is simple and reliable.

[0037] Specifically, the hydraulic drive assembly 5 includes a hydraulic drive member 51, a second spring 52, a connecting rod 53 and a pressure rod 54. The hydraulic drive member 51 is movably installed at the connection position between the water inlet channel 1 and the water passage chamber 3, and the second spring 52 provides the hydraulic drive member 51 with elastic force to support and block the water outlet of the water inlet channel 1. The connecting rod 53 and the pressure rod 54 are both swingably installed inside the shower head, one end of the connecting rod 53 is connected to the hydraulic drive member 51, and the other end is connected to the pressure rod 54. The other end of the pressure rod 54 is against the negative pressure chamber 4. When the shower head is filled with water, the hydraulic force pushes the hydraulic drive member 51 away from the water outlet of the water inlet channel 1, and at the same time drives the pressure rod 54 through the connecting rod 53. The end of the pressure rod 54 can press the negative pressure chamber 4 to force it to shrink. When the water is turned off, the hydraulic drive member 51 is reset under the action of the second spring 52, and drives the pressure rod 54 through the connecting rod 53, so that the end of the pressure rod 54 releases the negative pressure chamber 4, allowing the negative pressure chamber 4 to recover and generate negative pressure.

[0038] In one embodiment, a partition is provided at the end of the water inlet channel 1, a guide hole is provided in the middle of the partition, and the water outlet is provided around the guide hole. A guide column is provided at one end of the hydraulic driving member 51 to be telescopically inserted into the guide hole to improve the directional accuracy of the hydraulic driving member 51 when moving, and a mounting groove for accommodating the second spring 52 is provided at the other end of the hydraulic driving member 51 to prevent the second spring 52 from being separated from the working position when in use.

[0039] In order to improve the air tightness of the water passage chamber 3, a ball head 531 is provided in the middle of the connecting rod 53, and the ball head 531 is swingably installed in a swing groove outside the water passage chamber 3 (the ball head 531 is pressed and installed on the outer periphery of the inner frame 6 through a locking seat), and the swing is flexible. A clearance hole for one end of the connecting rod 53 to pass through is provided at the bottom of the swing groove, and a sealing ring 8 is provided between the ball head 531 and the swing groove to prevent the clearance hole from forming a pressure relief hole of the water passage chamber 3.

[0040] When in use, water enters the water inlet channel 1 of the shower head, and the water pushes the hydraulic driving member 51 to move. The hydraulic driving member 51 drives the pressure rod 54 to press the negative pressure chamber 4 through the connecting rod 53, and the negative pressure chamber 4 shrinks. When the shower head is turned off, the water force disappears, the hydraulic driving member 51 is reset, and at the same time, the pressure rod 54 is also reset, releasing the negative pressure chamber 4. The negative pressure chamber 4 restores its internal space under the action of elastic force, thereby having a vacuum effect on the water passage chamber 3, making it a negative pressure state, and being able to absorb and retain the residual water inside the shower head inside the shower head. In order to improve the negative pressure adsorption effect on water, when designing, under the premise of not affecting the flow direction, the design of the water passage chamber 3 is as small as possible, and at the same time, the higher the sealing, the longer the negative pressure effect can be maintained.

[0041] The utility model provides a negative pressure chamber 4 connected to the water chamber 3 in the shower head, which can shrink when water is inletted, and restore to form a negative pressure in the water chamber 3 when the water is turned off, so that the residual water in the water chamber 3 can be absorbed to prevent the residual water from being continuously or gradually discharged from the water outlet 2. Since the negative pressure chamber 4 proposed in the present application can be restored in time at the moment of turning off the water, the effect of stopping the water when the water is turned off can be truly achieved.

[0042] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
