Description

Technical Field

[0001] The present invention relates to the technical field of shower devices, and in particular to a handle control mechanism capable of linear reciprocating motion and a shower. Background Art

[0002] Conventional rotary valve cores primarily rely on a handle connected to the valve stem to rotate the stem, thereby controlling the opening and closing of the valve core or regulating flow. This means that the handle forms an arc-shaped rotation trajectory when controlling the valve core, which presents the following problems: First, the handle's arc-shaped rotation trajectory adjusts the valve core, and the adjustment position is not particularly intuitive. Second, the handle's arc-shaped rotation trajectory always tilts on both sides, making it prone to slipping when the user moves the handle left or right. This is especially true when showering, where the handle's smooth surface, lubricated by water and body wash, makes slipping even more likely.

[0003] In the prior art, one end of a guide conversion member is typically fixed to the valve stem, and a push rod is provided at the other end of the guide conversion member along the axial direction of the valve stem. The push rod and the guide conversion member are relatively movable, enabling linear movement of the push rod, which in turn drives the valve stem to rotate via the guide conversion member. However, this method has low stability, and the push rod is prone to shaking, resulting in a poor user experience. Summary of the Invention

Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0031] Embodiment

[0032] In combination Figures 1 to 7 As shown in the figure, the embodiment provides a handle control mechanism capable of linear reciprocating motion, which is used for converting the handle control mechanism of the valve core 17 valve rod movement, including a guide seat 1, a push rod 2, a guide conversion piece 3, a sliding block 4 and a first elastic member 5. The guide seat 1 is provided with a linear guide part 11, and the push rod 2 is movably installed on the linear guide part 11. The guide conversion piece 3 is connected to the valve rod at one end, and an active slot 6 is formed at the other end, and the sliding block 4 is movably installed in the active slot 6 and rotatably connected with the push rod 2. The first elastic member 5 provides a force for the sliding block 4, so that the sliding block 4 can be close to or away from the center of the valve rod, thereby providing a pre-tightening force for the movement of the push rod 2.

[0033] Among them, the linear guide part 11 refers to the linear track structure that limits the movement path of the push rod 2, which can be realized by sliding cooperation of guide rail and guide groove, and is used to ensure that the push rod 2 moves along a fixed track. The active slot 6 of the guide conversion piece 3 refers to the slot structure that accommodates the movement of the sliding block 4, which is used to constrain the displacement freedom degree of the sliding block 4 in a specific direction. The rotatable connection between the sliding block 4 and the push rod 2 refers to allowing the sliding block 4 to rotate around the axis of the push rod 2, which is used to adapt to the angle change between the linear motion of the push rod 2 and the rotary motion of the valve rod. The first elastic member 5 refers to an element that provides elastic pre-tightening force, which can be realized by a coil spring or a wave spring, and is used to eliminate the cooperation gap between the sliding block 4 and the active slot 6, and the cooperation gap between the guide rail and the guide groove.

[0034] Specifically, when the push rod 2 moves on the linear guide part 11, the linear pushing force is transmitted to the guide conversion piece 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, the angular deviation between the push rod 2 and the valve rod axis and the distance deviation formed after the slider 4 moves along the linear guide part 11 and the valve rod axis can be automatically compensated. The pre-tightening force of the first elastic member 5 makes the slider 4 always tightly adhere to the push rod 2, and further makes the bottom of the push rod 2 tightly adhere to the linear guide part 11, so as to avoid gap vibration in the movement process.

[0035] The present scheme allows the push rod 2 to make angular and positional adjustment in the movement process through the floating cooperation structure of the slider 4 and the movable groove 6, and meanwhile maintains the transmission stability by means of elastic pre-tightening.

[0036] Through the above technical scheme, the present application solves the stability problem of the push rod 2 in the linear movement conversion valve rod rotation process. The elastic pre-tightening structure effectively eliminates the cooperation gap of the moving parts, and prevents the push rod 2 from shaking. The floating cooperation of the slider 4 and the movable groove 6 ensures the smoothness of the operation process. The mechanism can realize intuitive linear displacement adjustment and avoid the skidding phenomenon caused by the inclination of the handle in the scene of shower and the like which needs to prevent skidding operation.

[0037] In the present embodiment, as shown in Figure 3 and Figure 4 , the guide conversion piece 3 is provided with a through slot 7 at the other end, and the side walls on both sides of the through slot 7 are provided with movable grooves 6; the slider 4 is movably arranged in the through slot 7, and both sides of the slider 4 are provided with movable parts 8 matched with the movable grooves 6; and the elastic member is arranged between one end face of the through slot 7 and the slider 4.

[0038] Among them, the through slot 7 refers to the slot structure penetrating through the upper and lower end faces of the guide conversion piece 3, which can be realized by a U-shaped or rectangular slot, and is used for accommodating the slider 4 and limiting the movement range of the slider 4. The movable groove 6 refers to the guide structure extending along the side walls on both sides of the through slot 7, which can be realized in the form of a groove, a through groove or a guide rail. The movable part 8 refers to the protruding structure arranged on both sides of the slider 4, which is used for forming a sliding connection with the movable groove 6. The first elastic member 5 refers to an element capable of elastic deformation, which is a spring in the present embodiment, and is sleeved on the limiting column 9 arranged on the end face of the slider 4, and the other end is arranged in the opening groove 10 of the end face of the guide conversion piece 3, which is used for providing pre-tightening force for the slider 4 and the push rod 2.

[0039] Specifically, the slot 7 at the other end of the guide conversion piece 3 forms a through channel, and the movable slot 6 on both sides cooperates with the movable part 8 on both sides of the slider 4, so that the slider 4 moves along the path defined by the movable slot 6 in the slot 7. The elastic member is arranged between the end face of the slot 7 and the slider 4. When the slider 4 is acted on by an external force, the elastic member generates a reverse force by 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 and the straight guide part 11.

[0040] Compared with the prior art, the connection between the guide conversion piece 3 and the push rod 2 in the prior art usually adopts a single movable slot 6 or a sliding surface, which lacks multi-directional constraint of the push rod 2, and is easy to cause the push rod 2 to shake during movement. The present application compensates for the shaking caused by the gap between the slider 4 and the push rod 2 and the gap between the push rod 2 and the straight guide part 11 by the through slot 7, the two movable slots 6 on both sides and the slider 4, and the pre-tightening action of the elastic member, and strengthens the stability of the mechanism.

[0041] Through the above technical solution, the present application can effectively reduce the shaking and deviation of the push rod 2 during linear motion, and enhance the running stability of the handle control mechanism. At the same time, the pre-tightening force of the elastic member can automatically compensate for the gap between the slider 4 and the push rod 2 and the gap between the push rod 2 and the straight guide part 11, avoiding the loosening caused by wear, thereby prolonging the service life of the mechanism.

[0042] In the present embodiment, the straight guide part 11 is a linear guide rail arranged 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 piece 3 is arranged on the push rod 2, for limiting the push rod 2 in the axial direction. As shown in Figure 2 and Figure 7 The lower end face of the guide conversion piece 3 and the limiting step 13 are also provided with a second elastic member 14, which is an elastic gasket, providing an axial pre-tightening force, to ensure that the linear guide groove 12 of the push rod 2 is always in contact with the linear guide rail in the axial direction, avoiding the shaking of the push rod 2. In the present embodiment, a first opening 22 is arranged on the outer upper side of the movable slot 6, to facilitate the installation of the slider 4; when the push rod 2 is installed on the straight guide part 11, the movable part 8 is arranged inside the movable slot 6, to avoid the slider 4 from falling off from the first opening 22.

[0043] Through the arrangement of the first elastic member 5 and the second elastic member 14, the push rod 2 is provided with axial and radial pre-tightening forces, to ensure that the linear guide groove 12 of the push rod 2 is always in contact with the linear guide rail in the axial and radial directions, avoiding the shaking of the push rod 2 and strengthening the stability of the mechanism.

[0044] The present embodiment also includes a control handle 15 connected to the other end of the push rod 2 and arranged outside the panel 19, to facilitate manual control by the user.

[0045] The application further provides a shower, as shown in Figure 6 and Figure 7 The shower comprises a main body 16 provided with a mounting cavity, the mounting cavity is provided with a rotary valve core 17, and a handle control mechanism capable of linear reciprocating motion is further included, and a guide seat 1 is fixed to the main body 16.

[0046] The guide seat 1 is fixed to the main body 16, that is, the guide seat 1 is mounted on the main body 16 of the shower at a preset position in a fixed connection mode, for example, bolt connection, welding or clamping structure can be adopted. The fixed mode can ensure that the guide seat 1 and the main body 16 form a rigid support relationship, so as to avoid displacement deviation during movement. The handle control mechanism capable of linear reciprocating motion refers to a linkage device including the guide seat 1, a push rod 2, a guide conversion piece 3, a sliding block 4 and an elastic member, which drives the guide conversion piece 3 to drive the valve rod to rotate through the linear motion of the push rod 2. The mechanism realizes movement trajectory conversion through the cooperation of the sliding block 4 and the movable groove 6, and maintains the movement stability through the elastic member.

[0047] Specifically, the rotary valve core 17 is installed in the main body 16 of the shower, and the valve rod is connected with one end of the guide conversion piece 3. The guide seat 1 is fixed in the main body 16, when the push rod 2 moves along the linear guide portion 11, the linear motion is converted into the rotary motion of the valve rod through the sliding of the sliding block 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 accurate rotation angle of the valve core through the guide conversion piece 3, so as to realize the flow regulation.

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

[0049] Compared with the prior art, the linearly moving push rod 2 greatly avoids the user's operation slipping in the shower, and can also be more intuitive to adjust. The problems of non-intuitive operation, easy slipping and poor stability of the mechanism in the control of the valve core of the shower are solved. The movement trajectory of the linear push rod 2 is convenient for the user to observe the adjustment position, and the reliable operation feeling can still be maintained in the humid environment.
