A position switching mechanism, a water outlet unit and a water outlet device

Abstract

The present invention discloses a position switching mechanism, a water outlet unit and a water outlet device. The position switching mechanism includes a body, three rods and a push button. The three rods are respectively rotatably installed on the body, and the push button is slidably installed on the body. Moreover, the push button can switch among three positions arranged along the second direction. The push button can directly drive one rod to rotate, and this rod can drive the other two rods to rotate. A first object is connected to the other two rods. No matter which end the push button is pushed to, the first object can be kept at the same position. The water outlet unit adopts this position switching mechanism. When switching among three water outlet functions by pushing, even passing through the middle gear position, the water flow will not flow out from the water outlet corresponding to the middle gear position, but will directly switch to the required gear function, thus effectively improving the user experience.

Description

Technical Field

[0001] The present invention relates to the technical field of water outlet units, and particularly to a position switching mechanism, a water outlet unit and a water outlet device. Background Art

[0002] To meet different requirements, existing water outlet units can usually be manually operated to achieve the switching of water outlets with various different styles of water splashes or various different water paths. Conventional switching methods include pressing switching, rotating switching, pushing switching, etc. Among them, the pressing switching method has fewer available gears, the rotating switching method generally requires both hands for operation, and the pushing switching method is more convenient.

[0003] For existing water outlet units that achieve the switching of water paths by pushing, generally there are only two water outlet functions. If more than two water outlet functions are to be set, when switching between the gears at both ends of the push button stroke, it is necessary to pass through the middle gear, which makes the switching process discontinuous and reduces the user experience.

[0016] From the above description of the present invention, it can be seen that compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. A position switching mechanism provided by the present invention is provided with a rotatable first rod, a second rod and a third rod, wherein the third rod is connected to a push button, and the push button can be switched back and forth between a first position, a second position and a third position in sequence. When the push button is pushed from the middle second position to the third position, the third rod is driven to rotate in the direction of the third position, and the second object is driven to move in the direction of the third position, and the third rod also abuts against the first rod, and the first rod is driven to rotate in the direction of the third position, and the first object is driven to move in the direction of the third position; when the push button is then pushed directly from the third position to the first position via the second position, the third rod is driven to rotate in the direction of the first position, and the second object is driven to move in the direction of the first position, and the third rod also abuts against the second rod, but because the abutting position of the third rod is located on the other side of the second axis compared with the first object, the first object will maintain a tendency to move in the direction of the third position, and will not be moved away from its original position by the movement of the push button toward the first position; through the position switching mechanism, in the process of switching the push button from the third position to the first position, the position of the first object will not change, while the position of the second object will switch.

A push button is provided, and the push button is pushed to move and press against the second rod, so that the first object can be moved toward the first position, so that the first object can be reset to the position corresponding to the first position or the second position of the push button.

[0019] 3. A toggle button spring is provided. After the toggle button is turned, the toggle button spring will push the toggle button to return to its original position, thereby preventing the toggle button from affecting the subsequent rotation of the second rod.

[0020] 4. An outlet unit provided by the present invention adopts the above-mentioned position switching mechanism on the outlet body, controls the on-off of the corresponding water channels through the first piston forming the first object and the second piston forming the second object, and since when the position switching mechanism switches from the third position to the first position, or directly switches from the first position to the third position, the first piston will be in the same position, but the second piston will change its position, it is possible to keep the first water outlet from discharging water during such switching, and then when the first water outlet needs to discharge water, the first piston can be reset by the dial button.

[0021] 5. A first piston spring is provided. When the water inlet stops, the first piston spring will push the first piston to the position where the water inlet is closed and not connected to the water passage, so that when the water is turned on next time, the water flow will flow out from the first water outlet, realizing the function of resetting after water cut-off.

[0022] 6. The outlet body includes a seat body and a valve body. Through the split design, it is convenient for the installation of the first piston and the second piston.

[0023] 7. The structures of the first piston and the second piston are the same, and both include a connecting plate, a piston rod and a sealing rubber ring. The connecting plate is used to form a toggle connection with the first rod, the second rod or the third rod, the piston rod is used to slide on the outlet body, and the sealing rubber ring is used to move with the piston rod and realize the switching of the water outlet function.

[0024] 8. A V-shaped rubber ring is provided to prevent water leakage in the first sliding cavity or the second sliding cavity when the piston rod slides.

[0025] 9. The present invention also provides an outlet device. The outlet unit described above is installed in the housing of the outlet device. Through this outlet unit, the outlet device can realize the switching of multi-functional water outlets, and when switching from the second water outlet to the third water outlet or vice versa, the first water outlet will not discharge water during this switching process.

[0026] 10. The water outlet paths communicating with the second water outlet and the third water outlet in the outlet device can also be used to form a water spray from a spray gun, expanding the usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] See Figure 1 , Figure 1 which shows a schematic structural diagram of an embodiment of a water outlet unit provided by the present invention. The water outlet unit adopts a position switching mechanism and can be installed in a corresponding housing to form a water outlet device.

[0045] The position switching mechanism adopted by the water outlet unit will be described below.

[0046] The position switching mechanism is used to control the movement of a first object and a second object arranged along a first direction in a second direction perpendicular to the first direction. It includes a body, a first rod 31, a second rod 32, a third rod 33, a push button, a toggle button 61 and a toggle button spring 62. Among them, in this water outlet unit, the first object is a first piston 401 and the second object is a second piston 402.

[0047] The body is used for the first object and the second object to be slidably installed along the second direction. The first rod 31 is rotatably installed on the body around a first axis 16 extending in a third direction perpendicular to the first direction and the second direction, and is connected to the first object in a toggling manner; the second rod 32 is rotatably installed on the body around a second axis 13 extending in the third direction, and is connected to the first object in a toggling manner; the third rod 33 is rotatably installed on the body around a third axis 17 extending in the third direction, and is connected to the second object in a toggling manner. In this embodiment, taking Figure 4 the plane where it is located as an example, the first direction is the left-right direction, the second direction is the up-down direction, and the third direction is perpendicular to Figure 4 the plane where it is located.

[0048] Taking Figure 4 the direction shown as an example, a waterway extending in the up-down direction is provided at the middle position of the body. The first axis 16 is arranged at the left side position of the waterway. The left end of the first rod 31 is rotatably connected to the top of the first axis 16, and a convex structure is provided at the right end of the first rod 31. This convex structure can cooperate with the chute provided on the first object to realize the toggling connection between the first rod 31 and the first object; between the left side of the waterway and the above-mentioned first axis 16, a second axis 13 is arranged. The middle position of the second rod 32 is rotatably connected to the top of the second axis 13, and a convex structure is provided at the left end position of the second rod 32. This convex structure can cooperate with the chute provided on the first object to realize the toggling connection between the second rod 32 and the first object; the above-mentioned third axis 17 is arranged at the right side position of the waterway. The right end of the third rod 33 is rotatably connected to the top of the third axis 17, and a convex structure is provided at the left end of the third rod 33. This convex structure can cooperate with the chute provided on the second object to realize the toggling connection between the third rod 33 and the second object.

[0049] It should be understood that the toggling connection means that when the first rod 31 or other rods rotate around the corresponding axis, the convex structure provided thereon moves along an arc trajectory. At the same time, due to the cooperation between the convex structure and the corresponding chute, the convex structure can correspondingly push the first object or the second object to slide by pushing against the side wall of the chute.

[0050] In addition, the push button is slidably disposed on the body along the second direction and is adapted to reciprocally switch between a first position, a second position, and a third position in sequence. And it is connected to the third rod 33 in a toggling manner on the same side of the second object relative to the third axis 17. Moreover, the push button is further configured to be adapted to drive the second object to move when switching from the second position to the third position, and to push against a position on the first rod 31 on the same side as the first object relative to the first axis 16 by means of the third rod 33 to drive the first object to move, and to drive the first object to move when switching from the second position to the first position, and to push against a position on the second rod 32 on the side different from the first object relative to the second axis 13 by means of the third rod 33 to drive the first object to move.

[0051] Refer to Figure 6 , Figure 6 is a bottom view, so its left - right orientation is opposite to that of Figure 4 Here, the direction shown in Figure 4 is still taken as the standard. The following descriptions including the left - right orientation are all based on the direction shown in Figure 4 The left end of the third rod 33 is located in the middle of the first rod 31 and the second rod 32 in the up - down direction. When the left end of the third rod 33 moves upward, the third rod 33 can push against the right end of the first rod 31. When the left end of the third rod 33 moves downward, the third rod 33 can push against the right end of the second rod 32. At this time, it will drive the left end of the second rod 32 to move upward. Since the convex structure on the second rod 32 is arranged at its left end, the first object will be driven to move upward.

[0052] Among them, in this embodiment, the push button includes a pushing member 21 and a clamping member 22. The pushing member 21 and the clamping member 22 are fixedly connected into one body by means of plugging or clamping. The pushing member 21 is provided with a convex structure for facilitating the user to push with a finger. The clamping member 22 is located below the pushing member 21 and is used to form a sliding fit with the body. Specifically, the clamping member 22 can form a gear - position matching structure with the body. For example, an elastically deformable elastic arm is arranged on the clamping member 22, and at the same time, grooves corresponding to the three positions of the push button are arranged on the body. By making the elastic arm fall into the corresponding groove, a sense of gear - position is provided for the pushing of the push button.

[0053] The toggle button 61 is slidably mounted on the body along the second direction and is located on the other side of the third rod 33 relative to the second rod 32. And it is configured to be adapted to drive the first object to move by pushing against a position on the second rod 32 on the side different from the first object relative to the third axis 17 after the push button pushes against the second rod 32 by means of the third rod 33. At the same time, one end of the toggle - button spring 62 abuts against the body, and the other end abuts against the toggle button 61 and is adapted to push the toggle button 61 away from the second rod 32.

[0054] Refer to Figure 6, the knob 61 is located below the right end of the second rod 32. In this illustration, the user can use their hand to move the knob 61 upward, that is, push the knob 61 in the direction towards the third position. The knob 61 will push the second rod 32 to rotate and pull the first object in the direction towards the first position, so that the first object can be reset. That is, when the knob 61 moves upward, it abuts against the right end of the second rod 32, and the left end of the second rod 32 moves downward, thus pulling the first object downward. The knob spring 62 can push the knob 61 to reset after the user's hand releases the knob 61, so that the knob 61 returns to the lower position, preventing the knob 61 from affecting the movement of the third rod 33.

[0055] In the water outlet unit provided in this embodiment, a position switching mechanism as shown above is adopted. The water outlet unit includes a water outlet body 10, a first piston 401, a second piston 402, a first piston spring 43, and several sealing rubber rings.

[0056] Among them, the water outlet body 10 forms the body of the above-mentioned position switching mechanism, the first piston 401 forms the first object of the above-mentioned position switching mechanism, and the second piston 402 forms the second object of the above-mentioned position switching structure.

[0057] Refer to Figure 4 or Figure 5 , the water outlet body 10 is provided with a first sliding cavity 102 and a second sliding cavity 105, and is provided with a water inlet 101 and a first water outlet 103 communicating with the first sliding cavity 102, a second water outlet 106 and a third water outlet 107 communicating with the second sliding cavity 105, and a water passage 104 for communicating the first sliding cavity 102 and the second sliding cavity 105.

[0058] Refer to Figure 6 , the first piston 401 is slidably assembled in the first sliding cavity 102 and is adapted to switch the communication between the water inlet 101 and the first water outlet 103 and the water passage 104 by sliding in the first sliding cavity 102; the second piston 402 is slidably assembled in the second sliding cavity 105 and is adapted to switch the communication between the water passage 104 and the second water outlet 106 and the third water outlet 107 by sliding in the second sliding cavity 105.

[0059] Refer to Figure 3 or Figure 4 , one end of the first piston spring 43 abuts against the water outlet body 10, and the other end abuts against the first piston 401, and is adapted to push the first piston 401 to close the communication between the water inlet 101 and the water passage 104. Through the first piston spring 43, when the water supply stops at the water inlet 101, the first piston 401 can be driven to open the communication between the water inlet 101 and the first water outlet 103, ensuring that water can flow out from the first water outlet 103 during the next use.

[0060] Specifically, referring to Figure 1 , the water outlet body 10 includes a seat body and a valve body fixedly connected as a whole. The seat body further includes a base 11, a first water sealing cover 12, a second shaft 13, a bottom cover 14, a second water sealing cover 15, a first shaft 16 and a third shaft 17. The bottom cover 14 is disposed on the bottom side of the base 11 and cooperates with the base 11 to jointly form the main body part of the seat body. The seat body is provided with a water inlet 101, a first water outlet 103, a second water outlet 106, a third water outlet 107 and a water passage 104, and is provided with two counterbore structures extending along the second direction, and these two counterbore structures can cooperate with the valve body to form a first sliding cavity 102 and a second sliding cavity 105 respectively. The first water sealing cover 12 is disposed on the base 11 and cooperates with the base 11 to form a water passage connecting the water inlet 101 and the first sliding cavity 102; the second water sealing cover 15 is disposed on the base 11 and cooperates with the base 11 to form the water passage 104. The first shaft 16, the second shaft 13 and the third shaft 17 are respectively used for rotatably mounting the first rod 31, the second rod 32 and the third rod 33, and the three can be fixed on the seat body by an adhesive bonding method and maintain a posture extending along the third direction. In addition, a sliding clamping structure is disposed on the upper surface of the first water sealing cover 12, and the clamping member 22 in the push button can be clamped on the first water sealing cover 12 and reciprocally move between a first position, a second position and a third position along the second direction.

[0061] The valve body includes a valve seat 18 and a valve cover 19. The valve seat 18 is a hollow cylindrical member, the side wall thereof is provided with a through hole for water passing, and one end thereof forms a sealing surface for sealing cooperation with the first piston 401 or the second piston 402. It can be inserted into the counterbore on the seat body, and then the counterbore is sealed by the valve cover 19, so as to clamp and fix the valve seat 18 on the seat body. A circular through hole is also provided on the valve cover 19, and a V-shaped rubber ring 191 is disposed between the valve cover 19 and the valve seat 18, and the opening direction of the V-shaped rubber ring 191 faces the inner side of the counterbore.

[0062] The first piston 401 and the second piston 402 have the same structure, and both include a connecting plate, a piston rod 41 and a sealing rubber ring 42. The connecting plate is further divided into a first connecting plate 51 and a second connecting plate 52, and the structures of the two are different.

[0063] Taking the second piston 402 as an example, referring to Figure 1, the second piston 402 includes a piston rod 41, a sealing rubber ring 42, and a second connecting plate 52. The piston rod 41 penetrates through the valve seat 18 and the valve cover 19 and extends outside the seat body. At the same time, the outer wall thereof abuts against the inner ring of the V-shaped rubber ring 191 to ensure that water does not flow out of the first sliding cavity 102 or the second sliding cavity 105 when the piston rod 41 slides. A groove extending circumferentially is also provided on the piston rod 41, and this groove can be used to assemble the sealing rubber ring 42. The sealing rubber ring 42 can move along with the sliding of the piston rod 41, so as to switch the connection between the water inlet 101, the water passage 104, and the first water outlet 103.

[0064] The first connecting plate 51 of the first piston 401 is fixedly connected to the piston rod 41 of the first piston 401 and is in a toggle connection with the first rod 31 and the second rod 32. The toggle connection here means that when the first rod 31 and the second rod 32 make rotational movements, they can correspondingly push the first connecting plate 51 to move in the second direction. The second connecting plate 52 of the second piston 402 is fixedly connected to the piston rod 41 of the second piston 402 and is in a toggle connection with the third rod 33.

[0065] Refer to Figure 6 , one end of the first rod 31 is rotatably installed on the first shaft 16, and its rod body is in a toggle connection with the first connecting plate 51; the middle part of the second rod 32 is rotatably installed on the second shaft 13, and one end thereof close to the first shaft 16 is in a toggle connection with the first connecting plate 51; one end of the third rod 33 is rotatably installed on the third shaft 17, and its rod body is in a toggle connection with the second connecting plate 52.

[0066] In addition, one end of the third rod 33 away from the third shaft 17 is in a toggle connection with the engaging member 22 in the push button. When the push button slides, it will drive the third rod 33 to rotate. And one end of the third rod 33 away from the third shaft 17 is located between the first rod 31 and the second rod 32. When the third rod 33 moves upward, the second connecting plate 52 moves upward. At the same time, the third rod 33 will push against one end of the first rod 31 away from the first shaft 16 and drive the first connecting plate 51 to move upward; when the third rod 33 moves downward, the second connecting plate 52 moves downward. At the same time, the third rod 33 will push against the end of the second rod away from its toggle connection with the first connecting plate 51 and drive the first connecting plate 51 to maintain the tendency of moving upward. Therefore, whether the third rod 33 moves upward or downward, the first piston 401 will maintain the state of closing the connection between the water inlet 101 and the first water outlet 103. At this time, the water inlet 101 is connected to the water passage 104.

[0067] Afterwards, when it is necessary to reset the first piston 401, the push button 61 is pushed upward. The push button 61 pushes the end of the second rod 32 away from the end where it is connected to the first connecting plate 51 in a toggling manner, and drives the first connecting plate 51 to move downward, thereby switching the first piston 401 from the state of closing the communication between the water inlet 101 and the first water outlet 103 to the state of closing the communication between the water inlet 101 and the water passage 104. At this time, the water inlet 101 is in communication with the first water outlet 103.

[0068] Specifically, referring to Figures 3 to 9 , the state changes of the water outlet unit when the first water outlet 103, the second water outlet 106, and the third water outlet 107 discharge water are respectively shown.

[0069] Among them, in the initial state, the push button is in the second position. At this time, the first piston 401 opens the communication between the water inlet 101 and the first water outlet 103. After that, the push button can first be switched to the third position. The push button drives the third rod 33 to rotate upward, and at the same time drives the first rod 31 to rotate upward. The first piston 401 closes the communication between the water inlet 101 and the first water outlet 103, and the second piston 402 closes the communication between the water passage 104 and the third water outlet 107. The water flows out from the second water outlet 106. After that, the push button can directly slide from the third position to the first position. During this process, the push button will pass through the second position, but at this time the water pressure will press the first piston 401, so that the first piston 401 remains in the state of closing the communication between the water inlet 101 and the first water outlet 103. The third rod 33 rotates downward, and at the same time drives the end of the second rod 32 connected to the second connecting plate 52 in a toggling manner to rotate upward, so that the first piston 401 continues to maintain the state of closing the communication between the water inlet 101 and the first water outlet 103, and makes the second piston 402 switch to the state of closing the communication between the water passage 104 and the second water outlet 106. The water flows out from the third water outlet 107.

[0070] In addition, the present invention further provides a water outlet device, which includes a housing and a water outlet unit shown in the above embodiment. The housing is provided with a water inlet passage and water outlet passages having the same number as the water outlet ports of the water outlet unit. The water outlet unit is fixedly connected inside the housing, and the water inlet 101 of the water outlet unit is in communication with the water inlet passage of the housing, and its respective water outlet ports are respectively in communication with the respective water outlet passages of the housing.

[0071] Among them, the two water outlet passages on the housing communicating with the second water outlet 106 and the third water outlet 107 of the water outlet unit are configured to be suitable for forming a spray gun water outlet. For example, the aperture at the outlet end of these two water outlet passages can be gradually reduced, so as to form a spray gun water with a greater water outlet impact force.

[0072] The present invention provides a position switching mechanism, a water outlet unit and a water outlet device. The water outlet unit utilizes the position switching mechanism to achieve the following: when switching among three water outlet functions by pushing, even if passing through the intermediate gear, the water flow will not flow out from the water outlet corresponding to the intermediate gear, but will directly switch to the required gear function, thereby effectively improving the user experience.

[0073] The above description of the specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation to the protection scope of the present invention. Modifications, equivalent replacements or other improvements to the embodiments of the present invention or some of its technical features obtained by those of ordinary skill in the art through logical analysis, reasoning or limited experiments in combination with common general knowledge, ordinary technical knowledge in the art and / or the prior art shall be included within the protection scope of the present invention.
