Description

Technical Field

[0001] This utility model relates to the field of kitchen and bathroom technology, and in particular to a stepless push-switch shower head. Background Technology

[0002] Shower heads with push-to-switch mechanisms typically employ a ratchet or rack and pinion structure internally. In use, a push button drives a push rod, which in turn drives the ratchet or rack, causing the ratchet or rack to rotate and thus switching the water flow onto the distributor. The problems with this ratchet or rack and pinion structure are: 1. The component structure is relatively complex, and the teeth are prone to wear or deformation after prolonged use; 2. In this structure, the two components are installed close together through meshing, resulting in a weak connection after assembly, which can lead to loosening and separation, causing the switching function to fail. Therefore, this invention provides a push-to-switch structure with a simpler structure and a more compact assembly of the drive components. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model proposes a switching structure for driving components that is simple in structure and has a firm and reliable connection.

[0004] A stepless push-to-switch shower head includes a shower head body and a push-to-switch component.

[0005] The shower head body is provided with a water inlet channel, a mounting cavity and a water outlet channel connected in sequence. A switching valve is provided in the mounting cavity. The switching shaft of the switching valve is rotatably set and extends out from the clearance port of the mounting cavity.

[0006] The push-to-switch assembly includes a rocker arm, a push rod, and an operating component. The rocker arm is fixedly mounted on the switching shaft and has a first connecting portion extending from its periphery. The push rod is slidably mounted inside the shower head body, with one end positioned near the switching shaft and having a second connecting portion. The operating component is movably mounted on the shower head body and is linked to the other end of the push rod.

[0007] To improve the connection strength, the first and second docking parts overlap and are provided with a linkage assembly structure. The linkage assembly structure includes a strip hole and a protruding post. The strip hole is located on one of the first and second docking parts, and the protruding post is located on the other of the first and second docking parts. The protruding post is inserted into the strip hole. When the push rod is in a sliding state, it drives the swing rod and the switching shaft to rotate through the linkage assembly structure.

[0008] The stepless push-to-switch shower head provided by this utility model has a linkage assembly structure between the push rod and the swing rod. The linkage assembly structure includes a strip hole and a protruding post, and the protruding post is inserted into the strip hole, thereby forming a simple and firmly connected linkage relationship between the push rod and the swing rod.

[0009] Preferably, the switching valve is an outlet water circuit switching valve or a flow switching valve.

[0010] Preferably, to further improve the connection between the first docking part and the second docking part, the linkage assembly structure further includes a limiting member, which is installed at the end of the protrusion and restricts the protrusion from separating from the strip hole.

[0011] Preferably, the limiting member is a screw with a head diameter greater than the width of the strip hole, and the end of the protrusion is provided with a screw hole, which is locked into the screw hole of the protrusion. The structure is simple and easy to assemble.

[0012] Preferably, the limiting member is a card with an assembly hole in the middle. The card is sleeved on the end of the protrusion through the assembly hole. The assembly hole and the protrusion are relatively fixed to each other by interference fit, thread, undercut or adhesive. The structure is simple and the cost is low.

[0013] Preferably, the strip-shaped hole is disposed on the first mating portion, and the protrusion is disposed on the second mating portion.

[0014] Preferably, the rocker arm and the switching shaft are assembled together by an inverted snap, and the cross-section of the hole in the middle of the rocker arm is the same as the cross-section of the end of the switching shaft, and neither of them is circular.

[0015] Preferably, the outer periphery of the cover of the mounting cavity is provided with a guide groove, and the push rod is slidably installed in the guide groove to prevent the push rod from disengaging from the slidable installation position.

[0016] Preferably, the cover of the mounting cavity is assembled with a locking screw, the push rod is positioned close to one of the locking screws, and a strip-shaped notch is provided on the side facing the locking screw. The head of the locking screw is located in the strip-shaped notch. The push rod's stroke is limited by the locking screw and the strip-shaped notch, which not only simplifies the structure but also prevents the push rod from moving excessively.

[0017] Preferably, the handle of the shower head body is provided with a strip-shaped mounting port, and the strip-shaped mounting port is coplanar with the sliding square of the push rod, and the operating component is slidably mounted on the strip-shaped mounting port.

[0018] Preferably, for ease of user operation, the strip-shaped mounting port is located on the side of the shower head body facing the user. The operating component includes a connecting plate and a push button. The connecting plate is slidably mounted inside the handle, and one end of it has a recessed-protrusion insertion structure with the end of the push rod. In the sliding state, the connecting plate drives the push rod to slide through the insertion structure. The push button is assembled together with the connecting plate and has an operating part extending from the strip-shaped mounting port.

[0019] As can be seen from the above description of this utility model, this utility model has the following beneficial effects: The stepless push-to-switch shower head provided by this utility model has a linkage assembly structure between the push rod and the swing rod. The linkage assembly structure includes a strip hole and a protruding post, and the protruding post is inserted into the strip hole, thereby forming a simple and firmly connected linkage relationship between the push rod and the swing rod. The linkage assembly structure also includes a limiting component, which is installed at the end of the protrusion and restricts the separation of the protrusion from the strip hole, further improving the connection between the first docking part and the second docking part; The locking screw used to tighten the cover of the mounting cavity also constitutes a component that restricts the formation of the push rod. This not only simplifies the structure but also prevents the push rod from moving excessively. Attached Figure Description

The structure is simple and the cost is low.

[0034] When the push rod 22 is in a sliding state, it drives the swing rod 21 and the switching shaft 11 to rotate through the linkage assembly structure 3.

[0035] In one embodiment, the handle of the shower body 1 is provided with a strip-shaped mounting port, and the strip-shaped mounting port is coplanar with the sliding square of the push rod 22. The operating component 23 is slidably mounted on the strip-shaped mounting port. Optionally, for ease of user operation, the strip-shaped mounting port is located on the side of the shower body 1 facing the user.
