[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] Example 1 is as follows:

[0041] Reference Figures 1 to 4 , a spray cleaning device for an intelligent cover plate, comprising:

[0042] The bracket 1 is provided with a slide rail 11;

[0043] The spray rod 2 is slidably connected to the slide rail 11 and can rotate at a preset angle relative to the slide rail 11;

[0044] The driving unit 3 drives the spray rod 2 to perform telescopic movement along the slide rail 11;

[0045] The deflection unit 4 is connected to the rear end of the spray rod 2 . Under the action of the deflection unit 4 , the spray rod 2 is deflected by a preset angle relative to the bracket 1 .

[0046] By setting a bracket 1, a spray rod 2, a driving unit 3, and a deflection unit 4, the driving unit 3 drives the spray rod 2 to slide along the slide rail 11 of the bracket 1. During the sliding process or when sliding into place, the deflection unit 4 drives the spray rod 2 to deflect to a preset angle, thereby being able to effectively reduce the height of the entire spray device while meeting the requirements of the spray distance and angle of the spray rod 2, thereby meeting the low-profile design requirements of the intelligent cover.

[0047] The deflection unit 4 comprises:

[0048] A slider 41 is slidably connected to the slide rail 11;

[0049] The linkage block 42 is movably connected to the slider 41 and has a first position and a second position. The rear end of the spray rod 2 is movably connected and cooperates with the linkage block 42;

[0050] Preferably, the linkage block 42 moves up and down relative to the slider 41, and the specific connection mode of the linkage block 42 and the slider 41 is sliding cooperation, and the rear end of the spray rod 2 is pivotally cooperated with the linkage block 42. When the spray rod 2 is extended or in full extension, the linkage block 42 moves to the first position, thereby driving the spray rod 2 to deflect in the positive direction, so that the front end of the spray rod 2 moves down and the rear end moves up; when the spray rod 2 is retracted or retracted to full extension, the linkage block 42 moves to the second position, thereby driving the spray rod 2 to deflect in the reverse direction, so that the front end of the spray rod 2 moves up and the rear end moves down.

[0051] Specifically, in this embodiment, the first position is a high position and the second position is a low position. In other embodiments, it can also be replaced by the first position being a low position and the second position being a high position, and the effect is the same.

[0052] A limiting portion 411 is provided on the slider 41. When the linkage block 42 is in the first position, it cooperates with the limiting portion 411 to prevent the linkage block 42 from being separated from the slider 41. An abutment portion 12 is provided on the bracket 1. When the linkage block 42 moves with the slider 41 to cooperate with the abutment portion 12, the abutment portion 12 enables the linkage block 42 to move to the second position relative to the slider 41.

[0053] An elastic member 43 is provided between the linkage block 42 and the slider 41. The elastic member 43 is preferably a spring. The elastic member 43 applies an elastic force to the linkage block 42 to move toward the first position. When the linkage block 42 is separated from the abutment portion 12, the linkage block 42 moves to the first position under the action of the elastic force.

[0054] The driving unit 3 preferably includes gears, and the driving source for driving the gears to rotate is preferably a motor. The driving unit 3 is transmission-connected to the spray rod 2 , or the driving unit 3 is rotationally connected to the slider 41 and drives the spray rod 2 through the slider 41 .

[0055] The rear part of the bracket 1 is provided with a rib 13. Specifically, a side wall 16 is provided on both sides of the slide rail 11 of the bracket 1. A rib 13 extending along the sliding direction of the spray rod 2 is provided on the inner surface of each side wall 16. The rib 13 is preferably a straight surface, an arc surface or a folded line rib 13. The abutment portion 12 is formed by the bottom surface of the rib 13. The top of the linkage block 42 abuts with the bottom surface of the rib 13. The top of the linkage block 42 is provided with a second guide slope 421. The front end of the bottom surface of the rib 13 is provided with a first guide slope 131. The linkage block 42 abuts with the bottom surface of the rib 13 under the guidance of the second guide slope 421 and the first guide slope 131. In other embodiments, only the top of the linkage block 42 may be provided with the second guide slope 421, or only the front end of the bottom surface of the rib 13 may be provided with the first guide slope 131.

[0056] A bracket limiting surface 14 is provided inside the bracket 1. When the spray rod 2 is deflected by a preset angle, the bottom surface of the spray rod 2 cooperates with the bracket limiting surface 14. A pressure wheel 15 is provided on the bracket 1. The pressure wheel 15 rolls with the top surface of the spray rod 2, and the pressure wheel 15 can reduce the sliding friction between the two.

[0057] Reference Figure 5 and Figure 6 When the spray rod 2 is a straight rod or an arc rod, a roller 5 is provided on the bracket limiting surface 14 to roll with the bottom surface of the spray rod 2, and the roller 5 can reduce the sliding friction between the two.

[0058] Working principle of embodiment 1:

[0059] When using, Figure 1 As shown, at this time, the spraying device is in an initial state of not working. After the motor is started, the motor drives the driving unit 3, and the driving unit 3 drives the spraying rod 2 to slide out along the slide rail 11, and the spraying rod 2 drives the slider 41 and the linkage block 42 to slide forward. At the same time, the linkage block 42 slides along the abutment portion 12 on the bottom surface of the pressure rib 13 until the linkage block 42 is separated from the abutment portion 12. At this time, as shown in FIG. Figure 2 As shown, the elastic member 43 drives the linkage block 42 to slide to the first position relative to the slider 41, and the linkage block 42 drives the spray rod 2 to deflect in the positive direction, so that the front end of the spray rod 2 moves down and the rear end moves up, so that water can be sprayed on the human body better. After the cleaning is completed, the motor drives the drive unit 3 to move in the reverse direction, and the drive unit 3 then drives the spray rod 2 to slide and retract along the slide rail 11, and the spray rod 2 drives the slider 41 and the linkage block 42 to slide backward. When the linkage block 42 abuts against the abutment portion 12 on the bottom surface of the pressure rib 13, the abutment portion 12 causes the linkage block 42 to move to the second position, thereby driving the spray rod 2 to deflect in the reverse direction, so that the front end of the spray rod 2 moves up and the rear end moves down, thereby completing the storage process of the spray rod 2.

[0060] Embodiment 2: It is different from Embodiment 1 in that:

[0061] In this embodiment, the elastic member 43 is not provided, but is replaced by a magnetic member (not shown) that is mutually attracted between the linkage block 42 and the bracket 1. When the linkage block 42 is separated from the abutting portion 12, the magnetic member is attracted to each other so that the linkage block 42 moves to the first position.

[0062] Embodiment 3: The driving method of the linkage block 42 from the second position to the first position can be selected from the driving methods of Embodiment 1 and Embodiment 2, which differs from Embodiment 1 in that:

[0063] Reference Figure 7 The spray rod 2 is a straight rod, the bracket limiting surface 14 is a straight surface, and the slide rail 11 is a straight track.

[0064] Embodiment 4: The driving method of the linkage block 42 from the second position to the first position can be selected from the driving methods of Embodiment 1 and Embodiment 2, which differs from Embodiment 1 in that:

[0065] Reference Figure 8 The spray rod 2 is an arc rod, the bracket limiting surface 14 is an arc surface, and the slide rail 11 is an arc track.

[0066] In some other embodiments, the linkage block 42 in the above embodiment that is slidably mounted on the slider 41 may be replaced by a linkage block 42 that is swingably mounted on the slider 41 , so that the linkage block 42 swings between the first position and the second position relative to the slider 41 .

[0067] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
