Description

Technical Field

[0001] The invention relates to the technical field of bathroom products, and in particular to a quick-draining overhead showerhead. Background Art

[0002] With the prior art showerheads, after use, a negative pressure state is easily formed in the internal water cavity of the showerhead, which causes the residual water in the water cavity to be unable to be discharged or to be discharged very slowly, resulting in a long dripping time. In particular, the long dripping sound at night will directly affect people's rest. In addition, the residual water that cannot be discharged will breed bacteria after a long period of time, affecting the health of water use, and may even form scale and block the water outlet, affecting the shower experience. Moreover, at low temperatures, the residual water in the water cavity is prone to freeze, causing the showerhead to be unable to be used normally. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a quick-draining overhead showerhead, which mainly solves the technical problem that the residual water in the water cavity of the overhead showerhead in the prior art cannot be quickly discharged after use.

[0004] To achieve the above object, the present invention is implemented by the following technical solutions:

[0005] A quick-draining overhead showerhead comprises a overhead showerhead shell, a water cavity is formed inside the overhead showerhead shell, a water inlet channel connected to the water cavity inside the overhead showerhead shell and a plurality of water spray holes for water discharge are arranged on the overhead showerhead shell, a residual water quick discharge port connected to the water cavity inside the overhead showerhead shell is also arranged on the overhead showerhead shell, a sealing member matched with the residual water quick discharge port is movably arranged at the residual water quick discharge port, and a switch control mechanism for controlling the action of the sealing member to open or close the residual water quick discharge port is also arranged on the overhead showerhead shell.

[0006] Furthermore, the open and closed states of the residual water quick drain outlet are configured to be associated with the water inlet and water stop states of the water inlet channel through the mutual cooperation of the sealing member and the switch control mechanism, and when water is flowing into the water inlet channel, the switch control mechanism automatically controls the sealing member and the residual water quick drain outlet to form a sealing cooperation under the action of the inlet water pressure to close the residual water quick drain outlet, and when water is stopped in the water inlet channel, the switch control mechanism automatically resets and controls the sealing member and the residual water quick drain outlet to release the sealing cooperation to open the residual water quick drain outlet.

[0007] Furthermore, the switch control mechanism includes a piston head and a linkage rod of a lever structure. The piston head is adapted to be arranged in the water inlet channel. The two ends of the linkage rod are respectively connected to the piston head and the seal, so that the inward and outward telescopic movement of the piston head relative to the water inlet channel can control the seal and the residual water quick drain port to form a sealing fit or release the sealing fit through the linkage rod.

[0008] Furthermore, an elastic reset member capable of acting on the piston head is also provided in the water chamber of the top shower housing, so that when the water supply to the water inlet channel is cut off, the piston head can be automatically pushed upward and reset into the water inlet channel through the elastic force of the elastic reset member, and then the sealing member and the residual water quick discharge port are controlled by the linkage rod to release the sealing cooperation.

[0009] Furthermore, the water inlet channel is arranged at the top of the top spray shell, the residual water quick discharge port is opened at the bottom of the top spray shell, the sealing member includes a sealing cover and a lever arm connected to the sealing cover, a first support and a second support are arranged on the inner wall of the water chamber of the top spray shell, the lever arm is rotatably connected to the first support so that the sealing cover forms a flip cover structure, the linkage rod is rotatably connected to the second support, and the short arm end of the linkage rod is movably connected to the end of the lever arm, the long arm end of the linkage rod is movably connected to the bottom of the piston head, one end of the elastic reset member is connected to the inner wall of the water chamber of the top spray shell, and the other end of the elastic reset member is connected to the bottom position of the long arm end of the linkage rod.

[0010] Furthermore, the elastic return member is a compression spring.

[0011] Furthermore, a sealing ring is embedded on the sealing cover to improve the sealing performance between the sealing cover and the residual water quick discharge port.

[0012] Furthermore, a C-shaped connecting portion is formed at the end of the short arm of the linkage rod toward the lever arm, and a round head structure that can be matched with the C-shaped connecting portion is formed at the end of the lever arm. Through the nested cooperation of the C-shaped connecting portion and the round head structure, the linkage rod and the lever arm can form a linkage, and the linkage rod can also produce a forward and backward micro-displacement relative to the lever arm.

[0013] Furthermore, the piston head has an annular peripheral wall extending along the inside of the water inlet channel, and a notch for water outlet is formed on the annular peripheral wall.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] In the quick-draining top showerhead described in the present invention, a residual water quick drain port for quickly draining residual water remaining in the water cavity is provided on the top showerhead shell, and a sealing member for blocking the residual water quick drain port and a switch control mechanism for controlling the action of the sealing member are also provided on the top showerhead shell. The action of the sealing member can be controlled by the switch control mechanism to thereby open or close the residual water quick drain port. When the action of the sealing member is controlled by the switch control mechanism to close the residual water quick drain port, the top showerhead can be used for showering normally, and when the action of the sealing member is controlled by the switch control mechanism to open the residual water quick drain port, the water cavity inside the top showerhead shell can be drained through the residual water quick drain port after the water inlet channel stops inflowing water. The water chamber is kept in balance with the external air pressure, and a negative pressure state is not generated inside the water chamber. At the same time, most of the residual water inside the water chamber can be quickly discharged outward from the residual water quick discharge port. Moreover, since the internal and external air pressures of the water chamber and the outside world are balanced, a small amount of residual water inside the water chamber can also flow out from the corresponding water spray holes. Compared with the existing conventional top showers, the problem of the residual water inside the water chamber being unable to be discharged or being discharged slowly under the action of the internal and external pressure difference after the top shower stops taking water is greatly improved. It can effectively avoid the breeding of bacteria in the residual water affecting the healthy water use, the formation of scale in the residual water clogging the water spray holes affecting the water output, or the freezing of the residual water due to low temperature affecting the normal use of the top shower, etc., which can greatly improve the user experience and enhance the product market competitiveness.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Please refer to the attached Figure 1 To Attachment Figure 6An embodiment of the present invention provides a quick-draining top shower, including a top shower shell 1, a water cavity is formed inside the top shower shell 1, and the top shower shell 1 is provided with a water inlet channel 11 connected with the water cavity inside the top shower shell 1 and a plurality of water spray holes 12 for water discharge, and the top shower shell 1 is also provided with a residual water quick drain port 13 connected with the water cavity inside the top shower shell 1, and a sealing member 2 adapted to the residual water quick drain port 13 is movably provided at the residual water quick drain port 13, and a switch control mechanism 3 for controlling the action of the sealing member 2 to open or close the residual water quick drain port 13 is also provided on the top shower shell 1. It can be understood that in the present embodiment, a residual water quick drain port 13 for quickly draining the residual water remaining in the water cavity is provided on the top shower housing 1, and a sealing member 2 for sealing the residual water quick drain port 13 and a switch control mechanism 3 for controlling the action of the sealing member 2 are also provided on the top shower housing 1. The action of the sealing member 2 can be controlled by the switch control mechanism 3 to open or close the residual water quick drain port 13. When the action of the sealing member 2 is controlled by the switch control mechanism 3 to close the residual water quick drain port 13, the top shower can be used for showering normally, and when the action of the sealing member 2 is controlled by the switch control mechanism 3 to open the residual water quick drain port 13, the water cavity inside the top shower housing 1 can be drained through the water inlet channel 11 after the water inlet channel 11 stops inflowing water. The residual water quick drain port 13 allows the water chamber to maintain a balance with the external air pressure, and no negative pressure is generated inside the water chamber. At the same time, most of the residual water inside the water chamber can be quickly discharged outward from the residual water quick drain port 13, and since the internal and external air pressures of the water chamber and the outside are balanced, a small amount of residual water inside the water chamber can also flow out from the corresponding water spray hole 12. Compared with the existing conventional top spray, the problem of the residual water inside the water chamber being unable to be discharged or being discharged slowly under the action of the internal and external pressure difference after the top spray stops taking water is greatly improved, and the problem of residual water breeding bacteria and affecting water health, residual water forming scale and clogging the water spray hole 12 and affecting water output, and residual water freezing due to low temperature and affecting the normal use of the top spray is effectively avoided, which can greatly improve the user experience and enhance the product market competitiveness.

[0027] Please refer to the attached Figure 3 To Attachment Figure 6In one preferred embodiment, the open and closed state of the residual water quick drain port 13 is configured to be associated with the water inlet and water stop state of the water inlet channel 11 through the mutual cooperation of the sealing member 2 and the switch control mechanism 3, and when the water inlet channel 11 is filled with water, the switch control mechanism 3 automatically controls the sealing member 2 and the residual water quick drain port 13 to form a sealing cooperation under the action of the inlet water pressure to close the residual water quick drain port 13, and when the water inlet channel 11 is stopped, the switch control mechanism 3 automatically resets and controls the sealing member 2 and the residual water quick drain port 13 to release the sealing cooperation to open the residual water quick drain port 13. It can be understood that in the present embodiment, the open and closed states of the residual water quick drain port 13 are configured to be associated with the water inlet and water stop states of the water inlet channel 11 through the mutual cooperation of the sealing member 2 and the switch control mechanism 3. In this way, when water is flowing into the water inlet channel 11, the switch control mechanism 3 is automatically triggered by the water inlet pressure and then the seal 2 is automatically controlled by the switch control mechanism 3 to form a sealing cooperation with the residual water quick drain port 13 to close the residual water quick drain port 13, so that the top shower can be used for normal showering. When the shower is finished and the water inlet channel 11 stops flowing, the water inlet channel 11 loses the water inlet pressure, and the switch control mechanism 3 automatically resets and controls the seal 2 to release the sealing cooperation with the residual water quick drain port 13 to open the residual water quick drain port 13, so that the residual water in the water cavity of the top shower housing 1 can be quickly discharged. There is no need to use electronic components for automatic control, but it is automatically triggered by the water inlet pressure, there is no hidden danger of electrical safety, and no manual operation is required by the user, and the user's normal showering habits are not changed, which has a good market prospect.

[0028] Please refer to the attached Figure 3 To Attachment Figure 6In one preferred embodiment, the switch control mechanism 3 includes a piston head 31 and a linkage rod 32 of a lever structure, the piston head 31 is adapted to be arranged in the water inlet channel 11, and the two ends of the linkage rod 32 are respectively connected to the piston head 31 and the sealing member 2, so that the upward and downward movement of the piston head 31 relative to the inward and outward extension of the water inlet channel 11 can control the sealing member 2 to form a sealing fit or release the sealing fit with the residual water quick discharge port 13 through the linkage rod 32. In this embodiment, preferably, an elastic reset member 33 capable of acting on the piston head 31 is also provided in the water cavity of the top spray housing 1, so that when the water inlet channel 11 stops flowing, the piston head 31 can be automatically pushed upward and reset to the inside of the water inlet channel 11 through the elastic force of the elastic reset member 33, and then the sealing member 2 and the residual water quick discharge port 13 are controlled to release the sealing fit through the linkage rod 32. It can be understood that in this embodiment, the switch control mechanism 3 includes a piston head 31, a linkage rod 32, and an elastic reset member 33 for automatic reset. The piston head 31 can move outward relative to the water inlet channel 11 under the action of the water pressure of the water inlet, thereby triggering the linkage rod 32, and driving the seal 2 through the linkage rod 32 to form a sealing match with the residual water quick discharge port 13 on the top spray housing 1. When the water inlet channel 11 stops inflowing water and loses the water pressure, the piston head 31 and the linkage rod 32 automatically reset under the action of the reset force of the elastic reset member 33, thereby driving the seal 2 to reset and release the sealing match with the residual water quick discharge port 13 on the top spray housing 1. The overall structure of the switch control mechanism 3 is simple and practical, easy to produce and assemble, and low in cost.

[0029] Please refer to the attached Figure 3 To Attachment Figure 6In one preferred embodiment, the water inlet channel 11 is arranged at the top of the top spray housing 1, the residual water quick discharge port 13 and the water spray hole 12 are opened at the bottom of the top spray housing 1, the sealing member 2 includes a sealing cover 21 and a lever arm 22 connected to the sealing cover 21, a first support 14 and a second support 15 are arranged on the inner wall of the water chamber of the top spray housing 1, the lever arm 22 is rotatably connected with the first support 14 so that the sealing cover 21 forms a flip cover structure, the linkage rod 32 is rotatably connected with the second support 15, and the short arm end of the linkage rod 32 is movably connected with the end of the lever arm 22, the long arm end of the linkage rod 32 is movably connected with the bottom of the piston head 31, one end of the elastic reset member 33 is connected to the inner wall of the water chamber of the top spray housing 1, and the other end of the elastic reset member 33 is connected to the bottom position of the long arm end of the linkage rod 32. In this embodiment, preferably, the elastic reset member 33 is a compression spring. A sealing ring 23 is embedded on the sealing cover 21 to improve the sealing performance between the sealing cover 21 and the residual water quick discharge port 13. In one of the preferred embodiments, a C-shaped connecting portion 321 is formed at the end of the short arm of the linkage rod 32 facing the lever arm 22, and a round head structure that can be matched with the C-shaped connecting portion 321 is formed at the end of the lever arm 22. Through the nested cooperation of the C-shaped connecting portion 321 and the round head structure, the linkage rod 32 and the lever arm 22 can be linked, and the linkage rod 32 can also produce a forward and backward micro-displacement relative to the lever arm 22 to provide sufficient freedom of movement. However, those skilled in the art should understand that, in other embodiments, the specific structure and setting position of the switch control mechanism 3 are not limited to the specific implementation mode disclosed in the present embodiment. The switch control mechanism 3 can also be set at an external position of the top spray shell 1 instead of being set inside the water cavity of the top spray shell 1 without considering the aesthetic appearance of the top spray, and the switch control mechanism 3 can also be other conventional linkage control structures, as long as it can be triggered by the water pressure when water enters the water inlet channel 11 and drive the sealing cover 21 to form a sealing cooperation with the residual water quick drain port 13 to close it, and can automatically reset and drive the sealing cover 21 to move to release the sealing cooperation with the residual water quick drain port 13 to open it when water stops entering the water inlet channel 11.

[0030] Please refer to the attached Figure 3 , Attachment Figure 5 , Attachment Figure 6In one preferred embodiment, the piston head 31 has an annular circumferential wall extending along the inside of the water inlet channel 11, and a notch for water discharge is provided on the annular circumferential wall. The piston head 31 is configured such that when water is flowing into the water inlet channel 11, the upper end of the piston head 31 is partially still embedded in the water inlet channel 11, and only the lower end of the piston head 31 is partially exposed, and will not completely separate from the water inlet channel 11, so that the piston head 31 can be reset relatively smoothly, and the height position of the notch on the annular circumferential wall of the piston head 31 is reasonably designed to ensure that the sealing cover 21 can accurately and quickly drain the residual water on the top shower housing 1 to the quick discharge port 13 when the shower is used, and then the water flow inside the water inlet channel 11 flows into the water cavity from the notch on the annular circumferential wall of the piston head 31 and then sprays out from each water spray hole 12 for showering. And because the nested cooperation of the C-shaped connecting portion 321 and the round head structure has a certain front and rear micro-displacement margin, after the sealing cover 21 and the residual water quick discharge port 13 are completely sealed together, the piston head 31 can continue to push the linkage rod 32 to move a certain stroke under the action of the incoming water pressure, thereby increasing the outflow of water in the water inlet channel 11 from the notch on the annular circumferential wall of the piston head 31, ensuring sufficient water flow for the shower.

[0031] As described above, the embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements do not deviate the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.
