Description

Technical Field

[0001] The invention relates to bathroom equipment, in particular to a shower. Background Art

[0002] A showerhead is a device used to control a combined shower head, and has functions such as switching water outlet terminals, water stopping and temperature adjustment. With the increase of shower head functions, this showerhead has evolved from a single handle to an operation box, which has greatly improved its convenience and intuitiveness. However, this operation box often requires a large number of electronic components to achieve switching, temperature adjustment and other tasks, which is relatively expensive and has high requirements for waterproofing. This has caused the price of this shower box to remain high, and it is often only installed on high-end products, and cannot be used by more people. Summary of the invention

[0003] The main technical problem to be solved by the present invention is to provide a sliding switching mechanical shower, which has light and convenient switching operation, good switching directivity and visual intuitiveness, and a relatively low full-mechanical structural cost.

[0004] In order to solve the above technical problems, the present invention provides a sliding switching mechanical shower, comprising: a first normally closed water outlet valve core, a second normally closed water outlet valve core and a dial button assembly; the dial button assembly comprises a dial button arranged on the surface of the shower, and the dial button can be toggled along the length direction of the shower;

[0005] When the dial button is in the middle position, the dial button assembly and the first normally closed water outlet valve core and the second normally closed water outlet valve core do not generate interaction force, and the first normally closed water outlet valve core and the second normally closed water outlet valve core are in the normally closed state at the same time; when the dial button moves to the left or right relative to the middle position, the dial button assembly and one of the first normally closed water outlet valve core and the second normally closed water outlet valve core generate interaction force, driving the first normally closed water outlet valve core or the second normally closed water outlet valve core to open.

[0006] In a preferred embodiment: the button assembly also includes a lifting rod; the middle position of the lifting rod is a rotating connection end, and the two ends of the lifting rod respectively extend into the lifting hanging platforms of the first normally closed water outlet valve core and the second normally closed water outlet valve core.

[0007] In a preferred embodiment, when the dial button moves from the middle position to both sides, the pushing force generated between the dial button and the lifting rod pushes one end of the lifting rod to sink and the other end to lift.

[0008] In a preferred embodiment: the lifting rod is located on one side of the dial button and extends from the middle position to both sides to form an inclined surface.

[0009] In a preferred embodiment, when one end of the lifting rod is lifted up, the one end of the lifting rod and the lifting hanging platform cooperate with each other along the lifting direction.

[0010] In a preferred embodiment: the button assembly also includes a slider linked to the button; the first normally closed water outlet valve core and the second normally closed water outlet valve core are provided with a lifting and hanging platform; the slider partially interferes with the lifting and hanging platform along the direction of translation of the slider.

[0011] In a preferred embodiment, when the slider interferes with the lifting platform, the slider and the lifting platform cooperate in a lifting direction.

[0012] In a preferred embodiment, the portion where the slider interferes with the lifting platform is an inclined surface.

[0013] In a preferred embodiment: the first normally closed water outlet valve core or the second normally closed water outlet valve core respectively has a sealing member linked to the lifting and hanging platform; when the lifting and hanging platform is located at the initial position, the sealing member seals the water outlet channel of the first normally closed water outlet valve core or the second normally closed water outlet valve core; when the lifting and hanging platform is lifted, the sealing member moves up accordingly to open the water outlet channel of the first normally closed water outlet valve core or the second normally closed water outlet valve core.

[0014] In a preferred embodiment: the first normally closed water outlet valve core or the second normally closed water outlet valve core respectively has a switching shaft connected between the sealing member and the lifting platform, and a water shut-off spring arranged in the valve body;

[0015] The upper end of the water shut-off spring is connected to the inner wall of the valve body as a fixed end, and the lower end is abutted against the boss on which the switching shaft is installed as a movable end; when the lifting platform is not lifted, the water shut-off spring is in a compressed state.

[0016] In a preferred embodiment: a reset spring is connected between the lifting platform and the inner wall of the valve body of the first normally closed water outlet valve core or the second normally closed water outlet valve core; when the lifting platform moves up, the reset spring is compressed to accumulate elastic reset force.

[0017] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0018] The present invention provides a sliding switching mechanical shower. By sliding the dial button left and right, an interaction force can be generated between the dial button assembly and the normally closed water outlet valve. This interaction force can drive the normally closed water outlet valve to open, thereby achieving the effect of opening a certain water outlet device. This operation method is very intuitive. The water outlet terminal can be switched by only moving the dial button assembly left and right. The switching process is very intuitive, and the force required for switching is independent of the water pressure. The user can maintain the same operating feel under any water pressure, and the comfort is relatively good. In addition, this shower adopts a fully mechanical method to achieve the purpose of switching the water outlet terminal, and the cost is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 3-Figure 5 This is a schematic diagram of the use status of the preferred embodiment 1 of the present invention;

[0023] The technical solution of the present invention is further described below through the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] refer to Figure 1-Figure 5 A sliding switch mechanical shower, comprising: a first normally closed water outlet valve core 1, a second normally closed water outlet valve core 2 and a dial button assembly 3; the dial button assembly 3 comprises a dial button 31 arranged on the surface of the shower, and the dial button 31 can be toggled along the length direction of the shower;

[0026] When the dial button 31 is in the middle position, the dial button assembly 3 does not generate interaction force with the first normally closed water outlet valve core 1 and the second normally closed water outlet valve core 2, and the first normally closed water outlet valve core 1 and the second normally closed water outlet valve core 2 are in the normally closed state at the same time; when the dial button 31 moves to the left or right relative to the middle position, the dial button assembly 3 generates interaction force with one of the first normally closed water outlet valve core 1 and the second normally closed water outlet valve core 2, driving the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 to open.

[0027] The above-mentioned sliding switching mechanical shower can generate an interaction force between the dial assembly 3 and the normally closed water outlet valve by sliding the dial button 31 left and right, and this interaction force can drive the normally closed water outlet valve to open, thereby achieving the effect of opening a certain water outlet device. This operation method is very intuitive. You only need to move the dial assembly 3 left and right to switch the water outlet terminal. The switching process is very intuitive, and the force required for switching is independent of the water pressure. The user can maintain the same operating feel under any water pressure, and the comfort is relatively good. In addition, this shower adopts a fully mechanical method to achieve the purpose of switching the water outlet terminal, and the cost is relatively low.

[0028] In order to achieve the effect of "the toggle assembly 3 generates an interaction force with one of the first normally closed water outlet valve core 1 and the second normally closed water outlet valve core 2, driving the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 to open", the following structure is adopted in this embodiment: the toggle assembly 3 also includes a lifting rod 32; the middle position of the lifting rod 32 is a rotating connection end 321, and the two ends of the lifting rod 32 extend into the lifting hanging platforms 11 and 21 of the first normally closed water outlet valve core 1 and the second normally closed water outlet valve core 2 respectively. In this way, the lifting rod 32 forms a seesaw structure, and as long as one end of the lifting rod is subjected to downward pressure or upward force, the other end will be lifted up or pressed down accordingly.

[0029] The dial button 31 and the lifting rod 32 satisfy the following action linkage relationship: when the dial button 31 moves from the middle position to both sides, the pushing force generated between the dial button 31 and the lifting rod 32 pushes one end of the lifting rod 32 to sink and the other end to lift.

[0030] In order to achieve this linkage relationship, the lifting rod 32 is extended from the middle position to both sides toward one side of the dial button 31 to form an inclined surface 322. In this way, as the distance of the dial button 31 moving to both sides increases, the lifting height of the lifting rod 32 increases.

[0031] The lifting rod 32 and the lifting hanging platform 11, 21 meet the following action linkage relationship: when one end of the lifting rod 32 is lifted, one end of the lifting rod 32 and the lifting hanging platform 11, 21 are linked and cooperated along the lifting direction. In this way, when one end of the lifting rod 32 is lifted, the corresponding lifting hanging platform 11, 21 will also be lifted.

[0032] Then, in order to ensure that the corresponding normally closed water outlet valve core will open to discharge water when the lifting hanging platforms 11 and 21 are lifted, in this embodiment, the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 respectively has a sealing member linked to the lifting hanging platforms 11 and 21; when the lifting hanging platforms 11 and 21 are located at the initial position, the sealing member seals the water outlet channel of the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2; when the lifting hanging platforms 11 and 21 are lifted, the sealing member moves upward accordingly to open the water outlet channel of the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2.

[0033] In order to realize the linkage between the seal and the lifting and hanging platforms 11, 21, the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 respectively has a switching shaft 14, 24 connected between the seal and the lifting and hanging platforms 11, 21. When the lifting and hanging platforms 11, 21 are lifted, the switching shaft 14 drives the seal to move upward. In addition, in order to keep the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 in a normally closed state when the lifting and hanging platforms 11 and 21 are not lifted, the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 is provided with a water spring 15 and 25 in the valve body; the upper end of the water-off spring 15 and 25 is connected to the inner wall of the valve body as a fixed end, and the lower end is in contact with the boss 16 and 26 on which the switching shaft 14 and 24 are installed, which is a movable end; when the lifting and hanging platforms 11 and 21 are not lifted, the water-off spring 15 and 25 is in a compressed state, and the elastic reset force generated by it presses down the boss 16 and 26, so that the switching shaft 14 and 24 drives the sealing element to seal the water outlet flow channel. When the lifting and hanging platforms 11 and 21 are lifted, the lifting force of the lifting and hanging platforms 11 and 21 is greater than the elastic reset force of the water-off spring 15 and 25, so that the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 can be smoothly opened.

[0034] Specifically, the lower end face of the sealing member is provided with a sealing ring 12, 22, the lower end face of the normally closed water outlet valve core is the water outlet, and the inner wall outer periphery of the water outlet extends upward along the height direction of the normally closed water outlet valve core to form a circle of enclosures 13, 23. When the lifting and hanging platforms 11, 21 are in the initial position, the sealing rings 12, 22 and the enclosures 13, 23 fit together, so that the water outlet is closed.

[0035] In addition, in order to allow the lifting platforms 11, 21 to automatically reset when the lifting rod 32 sinks, a reset spring is connected between the lifting platforms 11, 21 and the inner wall of the valve body of the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2; when the lifting platforms 11, 21 move upward, the reset spring is compressed to accumulate elastic reset force.

[0036] Finally, icons corresponding to different water outlet terminals are arranged on the surface of the shower, such as a hand-held shower and a head shower. When the dial button 31 moves to both sides relative to the middle position, the dial button 31 will point to one of the icons, and the user can know which outlet terminal is currently. In this embodiment, the normally closed outlet valve to which the dial button 31 moves will remain closed. Therefore, the icon arranged on the surface of the shower must be opposite to the actual normally closed outlet valve to achieve a normal indication effect. For example, the first normally closed outlet valve core 1 corresponds to the head shower, and the second normally closed outlet valve core 2 corresponds to the hand-held shower. The first normally closed outlet valve core 1 and the second normally closed outlet valve core 2 are respectively located on the left and right sides of the dial button 31. Then, the icon on the left side of the dial button 31 should be a hand-held shower, and the icon on the right side should be a head shower, so that it can correspond to the actual water outlet terminal.

[0037] Example 2

[0038] refer to Figure 6-Figure 8 The difference between this embodiment and embodiment 1 is that the pull rod 32 of the dial button assembly 3 is cancelled and replaced by a slider 33 linked to the dial button 31.

[0039] In order to achieve the effect of "the button assembly 3 generates an interaction force with one of the first normally closed water outlet valve core 1 and the second normally closed water outlet valve core 2, driving the first normally closed water outlet valve core 1 or the second normally closed water outlet valve core 2 to open.", the following structure is adopted in this embodiment: the first normally closed water outlet valve core 1 and the second normally closed water outlet valve core 2 are provided with lifting and hanging platforms 11 and 21; the slider 33 partially interferes with the lifting and hanging platforms 11 and 21 along the direction of translation of the slider 33.

[0040] The slider 33 and the lifting platforms 11 and 21 satisfy the following linkage relationship: when the slider 33 interferes with the lifting platforms 11 and 21, the slider 33 and the lifting platforms 11 and 21 cooperate in a lifting direction.

[0041] In order to achieve this linkage relationship, the part where the slider 33 interferes with the lifting and hanging platforms 11 and 21 is the inclined surface 331. In this way, when the interference occurs, the pressing force of the inclined surface 331 can push the lifting and hanging platforms 11 and 21 to move in the lifting direction.

[0042] In this embodiment, the structures of the lifting and hanging platforms 11, 21 and the sealing member are the same as those in Embodiment 1 and will not be described in detail here.

[0043] Finally, icons corresponding to different water outlet terminals, such as hand-held showerhead and head showerhead, are arranged on the surface of the shower head. When the dial button 31 moves to both sides relative to the middle position, the dial button 31 will point to one of the icons, and the user can know which outlet terminal is currently. In this embodiment, the normally closed outlet valve to which the dial button 31 moves opens. Therefore, the icon arranged on the surface of the shower head should be the same as the actual normally closed outlet valve to achieve a normal indication effect. For example, the first normally closed outlet valve core 1 corresponds to the head showerhead, and the second normally closed outlet valve core 2 corresponds to the hand-held showerhead. The first normally closed outlet valve core 1 and the second normally closed outlet valve core 2 are respectively located on the left and right sides of the dial button 31. Then, the icon on the left side of the dial button 31 should be the head showerhead, and the icon on the right side should be the hand-held showerhead, so that it can correspond to the actual outlet terminal.

[0044] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
