Description

Technical Field

[0001] This utility model relates to the field of shower device technology, and more specifically, to a handle control mechanism and a shower that can perform linear reciprocating motion. Background Technology

[0002] Conventional rotary valves primarily control the opening and closing of the valve core or regulate flow by rotating the valve stem via a handle connected to it. This means that when controlling the valve core, the handle rotates in an arc, which presents the following problems: First, the adjustment of the valve core is not visually intuitive; second, the handle's sides are always tilted during this arc, making it prone to slippage when the user moves it left or right; this is especially true during showering, where the smooth surface of the handle, combined with water and shower gel lubrication, makes slippage even more likely.

[0003] In existing technologies, one end of the guide conversion component is usually fixed to the valve stem, and a push rod is set at the other end of the guide conversion component along the valve stem axis. The push rod is movable relative to the guide conversion component, and the linear movement of the push rod drives the valve stem to rotate through the conversion component. However, this method has low stability, the push rod is prone to wobbling, and the user experience is poor. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a handle control mechanism and a shower that can perform linear reciprocating motion, so as to solve the above problems.

[0005] The present invention adopts the following solution:

[0008] The first elastic element acts on the slider so that the slider can move closer to or away from the axis of the valve stem, thereby providing a preload force for the movement of the push rod on the linear guide.

[0009] Furthermore, the other end of the guide conversion component is provided with a through slot, and the movable slots are provided on the side walls on both sides of the slot; the slider is movably disposed in the slot, and movable parts adapted to the movable slots are provided on both sides of the slider; the elastic element is disposed between one end face of the slot and the slider.

[0010] Furthermore, the linear guide portion is a first linear guide rail or a first linear guide groove disposed on the guide seat; the bottom of the push rod is provided with a second linear guide groove or a second linear guide rail adapted to the first linear guide rail or the first linear guide groove.

[0011] Furthermore, a first opening is provided on the upper outer side of the movable groove; when the push rod is installed on the linear guide, the movable part is placed inside the movable groove.

[0012] Furthermore, a limiting step adapted to the lower end face of the guide conversion component is provided on the push rod.

[0013] Furthermore, a second elastic element is provided between the lower end face of the guide conversion element and the limiting step.

[0014] Furthermore, the second elastic element is an elastic gasket.

[0015] Furthermore, it also includes a control handle, which is connected to the other end of the push rod and is located outside the panel.

[0031] Example

[0032] Combination Figures 1 to 7 As shown, this embodiment provides a handle control mechanism capable of linear reciprocating motion, used for switching the movement of the valve stem of the rotary valve core 17. The mechanism includes a guide seat 1, a push rod 2, a guide conversion component 3, a slider 4, and a first elastic element 5. The guide seat 1 has a linear guide portion 11, on which the push rod 2 is movably mounted. One end of the guide conversion component 3 is connected to the valve stem, and the other end has a movable groove 6. The slider 4 is movably mounted in the movable groove 6 and rotatably connected to the push rod 2. The first elastic element 5 provides a force to the slider 4, allowing it to move closer to or further away from the valve stem axis, thereby providing a preload force for the movement of the push rod 2.

[0033] The linear guide 11 refers to the linear track structure that restricts the movement path of the push rod 2. Specifically, it can be implemented using a sliding fit between the guide rail and the guide groove to ensure that the push rod 2 moves along a fixed trajectory. The movable groove 6 of the guide conversion component 3 refers to the groove-shaped structure that accommodates the movement of the slider 4, constraining the displacement freedom of the slider 4 in a specific direction. The rotatable connection between the slider 4 and the push rod 2 allows the slider 4 to rotate around the axis of the push rod 2, accommodating angular changes between the linear motion of the push rod 2 and the rotational motion of the valve stem. The first elastic element 5 refers to the element that provides elastic preload, specifically a helical spring or a wave spring, used to eliminate the clearance between the slider 4 and the movable groove 6, as well as the clearance between the guide rail and the guide groove.

[0034] Specifically, when the push rod 2 moves on the linear guide 11, the linear thrust is transmitted to the guide conversion component 3 through the cooperation of the slider 4 and the movable groove 6. Since the slider 4 can move along the movable groove 6 and rotate around the push rod 2, it can automatically compensate for the angular deviation between the push rod 2 and the valve stem axis, as well as the distance deviation formed between the slider 4 and the valve stem axis after moving along the linear guide 11. The preload applied by the first elastic element 5 keeps the slider 4 in close contact with the push rod 2, further ensuring that the bottom of the push rod 2 is in close contact with the linear guide 11, thus avoiding gap vibration during movement.

[0035] This design, through the floating engagement structure of slider 4 and movable groove 6, allows push rod 2 to adjust its angle and position during movement, while maintaining transmission stability with the help of elastic preload.

[0036] Through the above technical solution, this application solves the stability problem during the linear motion conversion of the push rod 2 to the rotation of the valve stem. The elastic pre-tightening structure effectively eliminates the clearance between moving parts and prevents the push rod 2 from shaking. The floating fit between the slider 4 and the movable groove 6 ensures smooth operation. In scenarios requiring anti-slip operation, such as showers, this mechanism can achieve intuitive linear displacement adjustment and avoid slippage caused by handle tilting.

[0037] In this embodiment, as Figure 3 and Figure 4 As shown, the other end of the guide conversion component 3 is provided with a through slot 7, and movable slots 6 are provided on the side walls on both sides of the slot 7; the slider 4 is movably disposed in the slot 7, and movable parts 8 that are adapted to the movable slots 6 are provided on both sides of it; the elastic element is disposed between one end face of the slot 7 and the slider 4.

[0038] In this design, the slot 7 refers to a channel structure that penetrates the upper and lower end faces of the guide conversion component 3. Specifically, it can be implemented using a U-shaped or rectangular channel to accommodate the slider 4 and limit its movement range. The movable slot 6 refers to a guide structure extending along the side walls of the slot 7. Specifically, it can be implemented using a groove, a through slot, or a guide rail. The movable part 8 refers to the protruding structure located on both sides of the slider 4, used to cooperate with the movable slot 6 to form a sliding connection. The first elastic element 5 refers to an element capable of elastic deformation. In this embodiment, a spring is used, which is sleeved on the limiting post 9 on the end face of the slider 4, with its other end located in the opening slot 10 on the end face of the guide conversion component 3, used to provide preload force for the slider 4 and the push rod 2.

[0039] Specifically, the slot 7 at the other end of the guide conversion component 3 forms a through channel, and the movable slots 6 on both side walls cooperate with the movable parts 8 on both sides of the slider 4, so that the slider 4 moves along the path defined by the movable slot 6 within the slot 7. An elastic element is disposed between one end face of the slot 7 and the slider 4. When the slider 4 is subjected to external force, the elastic element generates a reverse force through compression or stretching, so that the slider 4 is always in contact with the push rod 2 and the lower end of the push rod 2 with the linear guide part 11.

[0040] Compared with existing technologies, the connection between the guide conversion component 3 and the push rod 2 in existing technologies usually adopts a single movable groove 6 or sliding surface, which lacks multi-directional constraints on the push rod 2 and is prone to shaking during the movement of the push rod 2. However, this application, through the setting of the central slot 7, the two side movable grooves 6 and the slider 4, combined with the pre-tightening effect of the elastic element, compensates for the shaking caused by the gap between the slider 4 and the push rod 2 and between the push rod 2 and the linear guide part 11, thereby enhancing the stability of the mechanism.

[0041] Through the above technical solution, this application can effectively reduce the swaying and offset of the push rod 2 during linear motion, and enhance the operational stability of the handle control mechanism. At the same time, the preload of the elastic element can automatically compensate for the gaps between the slider 4 and the push rod 2, as well as between the push rod 2 and the linear guide 11, avoiding loosening of the fit due to wear, thereby extending the service life of the mechanism.

[0042] In this embodiment, the linear guide 11 is a linear guide rail mounted on the guide seat 1; the bottom of the push rod 2 is provided with a linear guide groove 12 adapted to the linear guide rail. A limiting step 13 adapted to the lower end face of the guide conversion member 3 is provided on the push rod 2 for axial limiting of the push rod 2. Figure 2 and Figure 7 As shown, a second elastic element 14 is also provided between the lower end face of the guide conversion component 3 and the limiting step 13. This elastic element is a gasket, which provides an axial preload to ensure that the linear guide groove 12 of the push rod 2 always abuts against the linear guide rail along the axial direction, preventing the push rod 2 from shaking. In this embodiment, a first opening 22 is provided on the upper outer side of the movable groove 6 to facilitate the installation of the slider 4. When the push rod 2 is installed on the linear guide part 11, the movable part 8 is placed inside the movable groove 6 to prevent the slider 4 from falling out of the first opening 22.

[0043] The above-mentioned first elastic element 5 and second elastic element 14 provide axial and radial preload for push rod 2, ensuring that the linear guide groove 12 of push rod 2 always abuts against the linear guide rail in the axial and radial directions, thus avoiding wobbling and enhancing the stability of the mechanism.

[0044] This embodiment also includes a control handle 15, which is connected to the other end of the push rod 2 and is located outside the panel 19, so as to facilitate manual control by the user.

[0045] This application further proposes a shower, such as Figure 6 and Figure 7 As shown, it includes a main body 16 with a mounting cavity, a rotary valve core 17 is provided in the mounting cavity, and a handle control mechanism capable of linear reciprocating motion. A guide seat 1 is fixed on the main body 16.

[0046] The guide seat 1 being fixed to the main body 16 means that the guide seat 1 is installed in a predetermined position on the shower body 16 through a fixed connection, such as by bolt connection, welding, or snap-fit ​​structure. This fixing method ensures that the guide seat 1 and the main body 16 form a rigid support relationship, avoiding displacement deviation during movement. The linearly reciprocating handle control mechanism is a linkage device including the guide seat 1, push rod 2, guide conversion component 3, slider 4, and elastic element. It drives the guide conversion component 3 to rotate the valve stem through the linear movement of the push rod 2. This mechanism realizes the conversion of motion trajectory through the cooperation of slider 4 and movable groove 6, and maintains motion stability through elastic element.

[0047] Specifically, a rotary valve core 17 is installed inside the shower body 16, with its valve stem connected to one end of the guide conversion component 3. The guide seat 1 is fixed inside the body 16. When the push rod 2 moves along the linear guide section 11, the linear motion is converted into the rotational motion of the valve stem by the sliding of the slider 4 in the movable groove 6. When the user operates the control handle 15, the linear displacement of the push rod 2 is converted into the precise rotation angle of the valve core via the guide conversion component 3, thereby achieving flow regulation.

[0048] In some specific embodiments, a protective shell 20 may be provided outside the main body 16, a protective cover 21 with an opening on the protective shell 20, and a panel 19 with a second opening 18 on the protective cover 21. The push rod 2 passes through the second opening 18 of the panel 19 and is connected to the external control handle 15.

[0049] Compared to existing technologies, the linearly moving push rod 2 greatly reduces the risk of slippage during showering, while also allowing for more intuitive adjustments. It solves the problems of unintuitive operation, slippage, and poor mechanism stability in shower valve core control. The linear push rod 2's movement trajectory makes it easy for users to observe the adjustment position and maintains reliable operation even in humid environments.
