Description

Technical Field

[0001] The utility model relates to the technical field of water tanks, in particular to a water tank button structure. Background Art

[0002] The toilet tank is equipped with a button structure that cooperates with the drain valve. By pressing the button structure, the action of the drain valve is controlled to ultimately achieve the flushing effect of the water tank. The existing water tank button structure mainly focuses on how to contact and cooperate with the drain valve to effectively control the opening and closing of the drain valve, while ignoring the operability of the button. The button requires a large pressing force value and / or a long pressing stroke, which affects user use. In addition, the traditional water tank button area is small, and there is a problem of difficulty in identifying the pressing. The existing buttons are usually designed with a relatively large area, which will cause the pressing position to easily deviate and cause problems such as excessive pressing force or inability to press, affecting the user experience.

[0003] In view of this, the applicant in this case conducted in-depth research on the above issues, and this case arose. Utility Model Content

[0004] The purpose of the utility model is to provide a water tank button structure, which overcomes the problems of excessive button force or excessive button stroke in the existing key structure while ensuring effective drainage, and has the characteristics of improving user experience and ensuring reliable functions.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A water tank button structure comprises a button rotating plate, a guide post rotating plate and a guide post which are arranged in sequence from top to bottom; the guide post is installed on the water tank cover so as to be movable up and down by a spring; the front end of the guide post rotating plate extends to the front position of the corresponding guide post and is rotatably installed on the water tank cover, the part of the guide post rotating plate close to the rear end contacts with the guide post to form a guide post force contact point, and the upper surface of the guide post rotating plate is respectively formed with a guide post front force area and a guide post rear force area in the front and back; the rear end of the button rotating plate extends to the rear position of the corresponding guide post and is rotatably installed on the water tank cover, and the lower surface of the button rotating plate is provided with a pressing convex portion, and the pressing convex portion is respectively formed with a button front force area and a button rear force area in the front and back; when the button rotating plate is in an unpressed horizontal state, the button front force area and the guide post front force area are separated from each other up and down, and the button rear force area and the guide post rear force area are contacted with each other up and down, and the mutual contact position is located in front of the guide post force contact point.

[0007] The upper surface of the key rotating plate is provided with keys.

[0008] The key is an inverted L-shaped piano key structure, and the key includes a horizontal part and a vertical part. The horizontal part is correspondingly stacked on the key rotating plate, and the vertical part is located in front of the key rotating plate and extends downward.

[0009] A cover plate is arranged on the upper part of the key rotating plate near the rear half, and the key is arranged on the upper part of the key rotating plate near the front half, and the key and the cover plate are arranged closely front and back.

[0010] The guide post rotating plate forms a downwardly bent yielding area between the corresponding guide post front force bearing area and the guide post rear force bearing area.

[0011] The key turn plate, guide column turn plate and guide column have two groups arranged side by side, and the two groups correspond to a full-row key group and a half-row key group constituting a water tank key structure. The full-row key group includes a full-row key turn plate, a full-row guide column turn plate and a full-row guide column, and the half-row key group includes a half-row key turn plate, a half-row guide column turn plate and a half-row guide column.

[0012] A full-row of keys is arranged on the full-row key rotating plate, and a half-row of keys is arranged on the half-row key rotating plate. The full-row keys and the half-row keys are arranged side by side.

[0013] After adopting the above scheme, the beneficial effect of the water tank button structure of the present invention compared with the prior art is that: by cleverly designing the coordination of the actions between the button rotating plate, the guide column rotating plate and the guide column, the lever ratio (power arm / resistance arm) formed during the pressing process changes from large to relatively small, that is, in the initial pressing section, the force value is large when the water level in the water tank is high, and the force area behind the button cooperates with the force area behind the guide column, and a relatively large lever ratio (i.e., a labor-saving lever) is used to achieve labor-saving pressing. When the drain valve starts to drain in the rear pressing section and the force value is small, it is switched to the coordination of the force area in front of the button and the force area in front of the guide column, and a relatively small lever ratio (i.e., a distance-saving lever) is used to achieve a short press in the second half of the button stroke, and a long guide column stroke is used to press down to drain, ensuring that the drain valve does not fail. Furthermore, the corresponding rotating shaft of the button rotating plate and the area with large force value nearby are hidden by a covering plate to prevent users from operating and affecting the experience. The present invention greatly improves the user experience and ensures reliable functions through simple adjustments to the structure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] This case involves a water tank button structure, such as Figure 1-3 As shown, it includes a button turn plate 1, a guide column turn plate 2 and a guide column 3 which are sequentially arranged up and down. The guide column 3 is installed on the water tank cover 5 by means of a spring 4 so as to be movable up and down. Specifically, an assembly groove 51 is formed on the water tank cover 5, and a mounting hole 52 is provided at the bottom of the assembly groove 51. The guide column 3 is arranged through the mounting hole 52. The button turn plate 1 and the guide column turn plate 2 are installed in the turn groove 51. The button turn plate 1 applies downward pressure to the guide column 3 via the guide column turn plate 2, and the guide column 3 cooperates with the spring 4 to achieve a resetting effect of moving up and down. The side of the water tank facing the user is the front direction, and the side corresponding to the front direction is the rear direction. As shown Figure 3 In the figure, the right side is the front direction of the water tank, and the left side is the rear direction of the water tank.

[0025] The front end of the guide post rotating plate 2 extends to the position in front of the corresponding guide post 3, and the front end of the guide post rotating plate 2 is rotatably mounted on the water tank upper cover 5, and is specifically connected by a rotating shaft, so that the guide post rotating plate 2 can swing around the rotating shaft. The portion of the guide post rotating plate 2 close to the rear end is in contact with the upper end of the guide post 3, and the contact position of the guide post rotating plate 2 forms a guide post force contact point 20. The upper surface of the guide post rotating plate 2 is formed with a guide post front force area 21 and a guide post rear force area 22 respectively.

[0026] The rear end of the key rotating plate 1 extends to the position behind the corresponding guide column 3, and the rear end of the key rotating plate 1 is rotatably mounted on the water tank cover 5, specifically connected by a rotating shaft, so that the key rotating plate 1 can swing around the rotating shaft. A pressing protrusion 10 is provided on the lower surface of the key rotating plate 1, and a key front force bearing area 101 and a key rear force bearing area 102 are formed on the front and rear of the pressing protrusion 10. Figure 3 As shown, when the key turn plate 1 is in a horizontal state without being pressed, the front force area 101 of the key and the front force area 21 of the guide column are separated from each other vertically, and the rear force area 102 of the key and the rear force area 22 of the guide column are in contact with each other vertically, and the mutual contact position is located in front of the guide column force contact point 20.

[0027] The working principle of the novel water tank button structure is described below through specific embodiments.

[0028] like Figure 4 As shown, the water tank button is in the initial state. If you press the outer side of the button rotating plate 1 F 按 The position of the guide post force contact point 20 of the guide post rotating plate 2 is the first force contact point S1, and the center of the contact position between the key-pressing rear force area 102 and the guide post rear force area 22 forms the second force contact point S2. Therefore, according to the lever principle, the following formula can be obtained: F 按 *d1=F 转 *d2;F 转 *d3=d4*F 阻 ; Substitute the values ​​of each force arm to obtain: F 按 *111=F 转 *52;F 转 *42=52*F 阻 ; That is, the initial leverage ratio = F 阻 :F 按 =111*42 / (52*52)=1.72, it is a force-saving lever at this time.

[0029] like Figure 5 As shown, the water tank button is in the initial state 1. Similarly, if the button is pressed on the outer side of the button rotating plate 1 F 按 At this point, the first force-bearing contact point S1 moves slightly backward, and the second force-bearing contact point S2 moves forward. According to the lever principle formula, the force arm values ​​are substituted into: F 按 *111=F 转 *56;F 转 *38=53*F 阻 ; That is, the initial leverage ratio = F 阻 :F 按 =111*38 / (56*53)=1.42, it is still a labor-saving lever at this time.

[0030] like Figure 6As shown, the water tank button is in the initial state 2. Similarly, if the button is pressed on the outer side of the button rotating plate 1 F 按 At this time, the first force contact point S1 continues to move slightly backward, and the front force area 101 of the key slowly contacts the front force area 21 of the guide column to become the second force contact point S2, that is, the second force contact point S2 slowly transitions from the contact area of ​​the corresponding rear force area 102 of the key to the contact area of ​​the corresponding front force area 101 of the key. According to the lever principle formula, the force arm values ​​are substituted as follows: 按 *111=F 转 *57;F 转 *37=54*F 阻 ; That is, the initial leverage ratio = F 阻 :F 按 =111*37 / (57*54)=1.33, which is a force-saving lever.

[0031] like Figure 7 As shown, the water tank button is in the rear pressing stage. Similarly, if the button is pressed on the outer side of the button rotating plate 1 F 按 At this time, the first force contact point S1 continues to move slightly backward, and the center of the contact position between the key front force area 101 and the guide column front force area 21 is the second force contact point S2. According to the lever principle formula, the force arm values ​​are substituted into: 按 *111=F 转 *74;F 转 *20=55*F 阻 ; That is, the initial leverage ratio = F 阻 :F 按 =111*20 / (74*55)=0.55, which is a distance-saving lever.

[0032] The present application cleverly designs the coordination of the actions among the button rotating plate 1, the guide column rotating plate 2 and the guide column 3 so that the lever ratio (power arm / resistance arm) formed during the pressing process changes from large to relatively small, that is, in the initial pressing section, the force value is relatively large when the water level in the water tank is high, and the force area 102 behind the button cooperates with the force area 22 behind the guide column to achieve effort-saving pressing by using a relatively large lever ratio (i.e., a labor-saving lever); in the rear pressing section, when the drain valve starts to drain water and the force value is relatively small, the force area 101 in front of the button cooperates with the force area 21 in front of the guide column to achieve a short press in the second half of the button stroke, and the full or half-row guide column stroke is long and pressed down to drain water, thereby ensuring that the drain valve does not fail.

[0033] Preferably, a key 6 that is easy to press is provided on the upper surface of the key turn plate 1. Further, the key 6 is an inverted L-shaped piano key structure, and the key 6 includes a horizontal portion 61 and a vertical portion 62, the horizontal portion 61 is correspondingly stacked on the key turn plate 1, and the vertical portion 62 is located in front of the key turn plate 1 and extends downward.

[0034] Preferably, a cover plate 7 is provided on the upper part of the key rotating plate 1 near the rear half, and the key 6 is provided on the upper part of the key rotating plate 1 near the front half, and the key 6 and the cover plate 7 are arranged closely front and back. In a preferred embodiment, the cover plate 7 is a plate structure integrally formed on the water tank upper cover 5. Through the design of the cover plate 7, the rotation axis of the key rotating plate 1 and the area with large force value nearby are hidden, specifically hidden in the water tank cover, so as to prevent users from accidentally pressing the area and affecting the experience.

[0035] Preferably, the guide column rotating plate 2 forms a downwardly bent yielding area 23 between the corresponding guide column front force area 21 and the guide column rear force area 22, so that during the key pressing process, from the initial stage to the rear pressing stage, the second force contact point S2 can be smoothly transitioned.

[0036] Preferably, the water tank has two modes, full row and half row, corresponding to the key rotating plate 1, the guide column rotating plate 2 and the guide column 3 having two groups arranged side by side, and the two groups correspond to the full row key group and the half row key group constituting the key structure of the water tank. Specifically, the full row key group includes the full row key rotating plate 1A, the full row guide column rotating plate 2A and the full row guide column 3A, and the half row key group includes the half row key rotating plate 1B, the half row guide column rotating plate 2B and the half row guide column 3B. The full row key group and the half row key group have the same working principle as described above, which will not be repeated here.

[0037] Furthermore, two groups of keys 6 are arranged side by side. Specifically, a full-row key 6A is arranged on the top of the full-row key turn plate 1A, and a half-row key 6B is arranged on the top of the half-row key turn plate 1B. The full-row keys 6A and the half-row keys 6B are arranged side by side to form labor-saving piano keys.
