Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are preferred embodiments of the invention and should not be considered as excluding other embodiments. Based on the embodiment of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.

In the claims, the specification and the drawings, unless otherwise expressly limited, the terms "first," "second," or "third," etc. are used for distinguishing between different elements and not for describing a particular sequence.

In the claims, the specification and the drawings, unless otherwise expressly limited, to the extent that directional terms such as "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inner", "outer", "upper", "lower", "front", "rear", "left", "right", "clockwise", "counterclockwise" and the like are used, the positional or orientational relationships illustrated in the drawings are based on the positional and orientational relationships illustrated in the drawings and are merely for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element so referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore should not be construed as limiting the scope of the present invention in any way.

In the claims, the description and the drawings of the present application, unless otherwise expressly limited, the term "fixedly connected" or "fixedly connected" is used, which is to be understood broadly, that is, any connection mode without displacement relation or relative rotation relation between the two, that is, including non-detachably fixed connection, and fixed connection through other devices or elements.

In the claims, the specification and the drawings, the terms "including", "comprising" and variations thereof, if used, are intended to be inclusive and not limiting.

Referring to fig. 1-5, which illustrate a faucet 10 of an embodiment of the present invention, taking a shower faucet used in a shower device as an example, it is to be understood that the faucet can also be a table top faucet or a faucet used in other locations, and the present invention is not limited thereto.

The faucet 10 includes: a body 1, a valve core 2 and an operation member 3. The valve core 2 is arranged in the body, and the operating part 3 is at least partially arranged in the body.

In the illustrated embodiment, the operating member 3 is used for operating the valve cartridge 2 to at least switch the water opening and closing functions of the faucet 10. It should be understood that the specific function that can be realized by the faucet 10 depends on the function type of the valve core 2 itself, and the present invention is not limited thereto, for example, the simple replacement of the valve core of the illustrated embodiment by a flow passage switching valve core, a mixing and heating valve core, and other multifunctional valve cores that operate in substantially the same manner, so as to provide the faucet with corresponding additional functions, is a routine operation that one skilled in the art can expect.

Specifically, the valve core 2 is provided with a valve rod 21 which can rotate around a first axis at least relative to the valve body, and the position of a sealing body in the valve core is relatively moved through the rotation of the valve rod, so that the water flow characteristic is changed, and the corresponding function of the valve core is realized.

In the illustrated embodiment, the first axis and the second axis, described below, are both axes that are perpendicular to the wall surface after the faucet is installed, according to the operating habits of the shower faucet. Generally speaking, the first axis does not coincide with the geometric axis of the valve body, and therefore the valve element 2 is basically referred to as the normal valve element as described above, rather than as a rotary valve element, in which the rotation axis only coincides with the geometric axis of the valve body and the rotation stroke is large. Taps using this rotary cartridge do not in fact have the drawbacks described above and are therefore outside the scope of the present invention.

Further, the operating member 3 is provided with an actuating portion 31, a rotating portion 32 and a toggle portion 33 which are connected into a whole, and the term "connected into a whole" refers to that the components have no relative motion relationship and can move as a whole, so that the operating member includes a split type fixed connection structure and an integrated structure. The actuating part 31 extends out of the body 1 for direct operation by a user, the rotating part 32 rotates at least relative to the body around a second axis parallel to the first axis, and the toggle part 33 is movably connected with the valve rod 21 so as to toggle the valve rod to drive the valve rod to move along a preset path which the valve rod has when the valve rod rotates, namely, rotate relative to the body around the first axis, thereby realizing the operation of the valve 2.

It should be noted that the toggle operation means that when the valve rod 21 has a certain preset path, a certain direction of driving force is only required to be applied to the valve rod through the toggle portion 33 of the operating member, and the driving force can actuate the valve rod without deviating from the original preset moving path. The present invention provides a path for the valve rod 21 to be pre-set around the first axis, the toggle portion 33 is configured to provide a real-time or instantaneous torque component at the connecting position between the two when the valve rod rotates, and the valve rod 21 can be actuated, and the present invention will be described in detail below.

Therefore, in the above-mentioned operating element 3, on the basis of realizing effective operation on the valve core 2, the first axis is parallel to the second axis, that is, the first axis and the second axis do not overlap, so that compared with the existing valve core operating structure, under the condition of realizing the same operating hand feeling, the radial stroke of each outermost point of the operating element 3 is reduced, and the rotation stroke is also effectively reduced. When it is applied to the faucet 10, it is possible to extend the body 1 a little to cover the turning part 32 and the dial part 33 of the operating member 3, and the radial dimension of the body 1 does not need to be designed to be very large to give way to the turning of the turning part 32. Thus, the faucet 10 employing the above-described construction can meet the requirements of aesthetics, faucet product general standards, and manufacturing costs.

Correspondingly, the body 1 should be configured to fully house the turning part and the dial 33 within the body, at least in one stroke position of the turning part 32. As shown in fig. 4, when the rotating portion 32 is in the minimum stroke position, it is completely housed inside the body 1; as shown in fig. 5, when the rotating portion 32 is at the maximum stroke position, only a small portion of the rotating portion is exposed outside the body 1.

It goes without saying that, apart from the cost considerations, the body 1 in the exemplary embodiment can be extended slightly further so that it can be covered at any stroke position of the rotary part 32. However, in the illustrated embodiment, the valve element 2 and the operation element 3 are sequentially installed at the end of the body 1 from the inside to the outside; the end of the turning part 32 remote from the valve stem 21 is of planar configuration and is flush with the end of the body 1 when it is at the minimum operating stroke. This embodiment thus achieves the object of the invention with a relatively low material cost.

In addition, as can be seen by referring to fig. 2, the operating member 3 is accommodated in the main body 1 for the most part, and a user can only see that the actuating portion 31 protrudes from the main body 1 from the outside, and there is no seam where a plurality of components are connected outside, so that the integrity of the faucet is effectively improved, and the defects that the traditional faucet is difficult to clean after long-term use and the operation feel is affected are overcome.

In particular, the illustrated embodiment shows a specific configuration of the connection between the toggle 33 and the valve stem 21. The toggle portion 33 is fixedly provided with a pushing portion 331, the valve rod 21 is provided with a sliding groove 211 matched with the pushing portion, the sliding groove extends along the radial direction of a rotating surface of the valve rod rotating around the first axis, and the pushing portion 331 is in sliding fit with the sliding groove 211.

In a specific operation, the rotating portion 32 is driven by an external force to rotate around the second axis, and the toggle portion 33 rotates therewith and transmits a torque around the second axis to the valve stem 21 through the abutting portion 331. Because the valve rod 21 is restricted by the valve body and can not rotate around the second axis, and the preset motion path is rotated around the first axis, the toggle part 33 transmits the abutting force which can cause the valve rod 21 to have the preset motion trend to the abutting position of the abutting part 331 on the sliding groove 211, so that the transmitted torque is decomposed into the abutting force and other non-driving forces which are offset due to the fixation of the valve body. The reaction force of the abutting force makes the abutting portion 331 have a tendency to slide along the valve rod, so that when the contact position of the abutting portion 331 and the sliding groove 211 moves along the radial direction of the valve rod rotation plane, the abutting force constitutes a driving force for causing the valve rod 21 to move along the preset path, thereby providing a torque rotating around the first axis to the valve rod stably in real time to realize the above-mentioned toggle.

In the above embodiment, when the rotating portion 32 is at the minimum stroke position (corresponding to fig. 4), the abutting portion 331 is configured to be at the position closest to the valve body; and when the rotating portion 32 is at the maximum stroke position (corresponding to fig. 5), the abutting portion 331 is configured to be at the position farthest from the valve body.

In the embodiment, the pushing part 331 and the sliding groove 211 are slidably matched to realize the pushing, and as can be seen from the figures, the pushing part 331 is structured as a pin shaft connected with the pushing part 33 into a whole, and compared with other special-shaped pushing parts, the pin shaft can realize simple and convenient assembly, has small assembly tolerance, does not need excessive debugging and has better operation hand feeling for users. In this embodiment, the abutting portion 331 configured as a pin is parallel to the first axis and the second axis, so as to improve the transmission efficiency.

It is conceivable that in another embodiment, the arrangement of the abutting portion and the slide groove is completely reversed from that of the embodiment, but the same effect can be achieved. Namely, the valve rod 2 is fixedly provided with a butting part, the toggle part 33 is provided with a sliding groove matched with the butting part, the sliding groove extends along the radial direction of a rotating surface of the toggle part rotating around the second axis, and the butting part is in sliding fit with the sliding groove.

Further, the toggle part 33 is provided with an abdicating groove 332 facing the end surface of the valve rod 21, and the valve rod 21 is at least partially inserted into the abdicating groove 332. Such an arrangement effectively saves space inside the body 1, reducing its radial dimensions, with respect to embodiments in which the dial 33 is not directly opposite the stem 21. Accordingly, in other embodiments, the reverse arrangement may be adopted, that is, the valve rod 21 is provided with an abdicating groove for inserting the toggle part 33.

It goes without saying that a water inlet channel and a water outlet channel are also arranged in the body 1 and are respectively in fluid communication with the water inlet and the water outlet of the valve core 2 so as to realize the water inlet and the water outlet of the faucet. And in the illustrated embodiment, since the tap 10 is a shower tap, it is required to have at least a water on/off function and a hot and cold water adjusting function, and thus, the valve cartridge 2 is selected as a valve cartridge capable of performing both functions. In the corresponding structure, the valve rod 21 of the valve core 2 can also rotate around a third axis which is perpendicular to the first axis, and the water inlet proportion of a cold and hot water channel in the valve core is changed by operating the valve rod to rotate around the third axis, so that the cold and hot water adjusting function is realized.

In one embodiment, the valve core 2 is provided with a first ball body, which is connected with the valve rod 21 and the sealing body in the valve core into a whole, so that the valve rod 21 is operated to drive the first ball body to rotate around any axis, and further the relative position of the sealing body is switched, so as to realize the water opening and closing function and the cold and hot water adjusting function. The rotary part 32 is in turn designed as a second ball or as a part of a second ball, in order to have the same three-dimensional rotary behavior in accordance with the valve slide 2.

Inevitably, the center of sphere of the first sphere is located on the first axis, and the center of sphere of the second sphere is located on the second axis, so that at least the valve rod 21 can rotate around the first axis, and the rotating part 32 can rotate around the second axis, thereby realizing the above operation. In the present embodiment, the above operations are corresponding to the switching of the water on/off function, that is, fig. 4 corresponds to the water off state of the faucet 10, and fig. 5 corresponds to the water boiling state of the faucet 10. Correspondingly, the center of the first sphere is also located at the third axis, i.e. at the intersection of the first and third axes, so that in fig. 5, when the actuating portion 31 rotates in a direction perpendicular to the inside and outside of the paper, the cold and hot water adjusting function is realized. In this embodiment, the third axis is the geometric axis of the valve stem.

In another embodiment, the valve cartridge 2 is not provided with a ball structure therein, and the stem 21 thereof is configured to be rotatable only about the first axis and the third axis. The valve rod has eccentric rotation characteristics as a whole, and the third axis is a geometric axis of the operating end of the valve rod. Such a valve body is a conventional valve body, and specifically, a structure shown in patent document CN209026248U can be referred to.

Therefore, in the illustrated embodiment, when the rotating portion 32 is at the minimum stroke position, corresponding to the water-off state of the faucet 10, the user can only see the actuator 31 protruding from the main body 1 from the outside, and the actuator 31 is configured as a thin rod in this embodiment, which has better integrity and state indication.

Preferably, a fixed seat 11 is fixedly arranged in the body 1, and a first cavity is formed in the fixed seat. The rotating part 32 is at least partially accommodated in the first cavity, and a spherical inner surface matched with the spherical outer surface of the rotating part 32 is formed in the first cavity, so that the rotating part 32 is supported and guided, and the structural stability and the operation hand feeling are improved.

The utility model discloses further still provide corresponding shower equipment, will tap 10 inserts the water supply source to install shower pipe and gondola water faucet, make shower equipment have the advantage of above-mentioned tap 10 equally.

The description of the above specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention. Modifications, equivalents and other improvements which may be made to the embodiments of the invention or to some of the technical features thereof by a person of ordinary skill in the art through logical analysis, reasoning or limited experimentation in light of the above teachings of the invention or the above embodiments are intended to be included within the scope of the invention.
