[0030] Detailed Implementation

[0031] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0032] This utility model provides a waterproof structure for an electronically controlled handle, such as Figures 1-6 As shown, it includes a button 3, a circuit board 4, a waterproof plug 5, a connecting cable 6, and a handle body 7;

[0033] The handle body 7 is provided with a sewage flow chamber 71 and a live mounting chamber 72, which are connected by a through hole 74.

[0034] The circuit board 4 is the core component of the handle, and it has an electronic switch and indicator lights to prompt the user to turn the device on and off. The circuit board 4 and the button 3 are both installed in the live mounting cavity 72. The button 3 is located above the circuit board 4. One end of the connecting wire 6 is located inside the live mounting cavity 72 and connected to the circuit board 4, while the other end extends out of the live mounting cavity 72.

[0035] The waterproof plug 5 is fitted onto the connecting line 6 to seal the through hole 74. Wastewater flows through the cavity 71 and the live installation cavity 72, which are isolated from the waterproof plug 5 by a rigid housing 73. In a preferred embodiment, the rigid housing 73 is a plastic rib, and the rigid housing 73 is integrally connected to the handle body 7.

[0036] The waterproof structure of the electronic control handle also includes a waterproof patch 1, which covers the button 3 and the junction of the button 3 and the handle body 7. The waterproof patch 1 can indicate the user's function operation and also effectively prevent external water from entering the live mounting cavity 72.

[0037] The waterproof structure of the electronically controlled handle also includes a fastener 2, which is used to fix the button 3 and the circuit board 4 to the handle body 7, ensuring that the water dispensing button and the circuit board are in a single position, thus enhancing the user experience. In a preferred embodiment, the fastener 2 is a screw.

[0038] Button 3 is the cover plate of the circuit board and also the button of the electronic switch. It is raised in the middle and hollowed out around the perimeter to form vertical elasticity. By deforming vertically, the electronic switch in the circuit board 4 is turned on and off. Specifically, button 3 is a plastic button.

[0039] In a preferred embodiment, the waterproof plug 5 is connected to the connecting wire 6 through a secondary molding process. The waterproof plug 5 is a PVC plug; specifically, the waterproof plug 5 passes through the through hole 74 and is tightened to form a seal, preventing water from flowing into the live mounting cavity 72 from the hole. The connecting wire 6 is soldered to the circuit board 4 and is a double-insulated PVC connecting wire 6. The handle body 7 is an ABS handle.

[0040] The working principle of this utility model is as follows:

[0041] Internal waterproofing: Reference Figure 5 As shown, sewage enters the handle body 7 in the direction of the arrow. The circuit board is encased in the live mounting cavity 72 on the upper part of the handle. One side and the bottom are made of one piece of plastic (i.e., a hard shell 73), which completely prevents water from entering. Only the through hole 74 is connected to the sewage flow cavity 71, but the through hole 74 is also sealed with a waterproof plug 5. Even if the internal wire is pulled hard, this position is firmly sealed and no water will enter the cavity.

[0042] External waterproofing: Water may remain on the outside of the handle during use. The perimeter of the live mounting cavity 72 is completely sealed with waterproof patch 1, so even if there is water on the outside, it will not enter the live mounting cavity 72. In addition, the waterproof patch is partially transparent and has an indicator light to remind the user whether to turn on the device.

[0043] Quick-installation structure: such as Figure 6 As shown, the connecting wire 6 and the circuit board 4 are inserted together from the leftmost arrow position. The connecting wire 6 is pulled tight from the back to make the waterproof plug fit into the hole position. The circuit board 4 at the front end is fitted over the screw post in the handle body 7, so that the circuit board 4 and the connecting wire 6 are fixed inside. The button 3 is fixed to the screw post with fastener 2 (such as 1 screw). Then the waterproof patch 1 is attached to it. The whole assembly is simple and easy to operate, and the waterproof effect is good.

[0044] Existing electronic control handles have waterproof structures that occupy a large space, affecting airflow; and they are difficult to assemble, requiring a long insertion distance into the handle without tilting, increasing labor time. In contrast, this invention has excellent waterproof performance (waterproof rating up to IP24); a simple assembly structure, easy operation in workshop production, and reduced labor costs; a small footprint, increasing airflow and reducing the effect of dirt jamming; in addition, the integrated layered structure of the handle in this invention is sturdy and reliable, and can withstand greater pressing pressure, improving the button feel.

[0045] The utility model also can be understood as: the electric body and connecting line first pass through the hole in the middle of handle, again this fixed in handle surface recess, with a screw fixed, and stick a layer of waterproof label on it.

[0046] In conclusion, the utility model discloses to solve the deficiency in the prior art, provide a system protection structure that can quickly assemble and solve the handle function failure caused by water seepage, the structure can effectively prevent water seepage and cause handle function failure, and can quickly assemble, reduce workshop artificial working hours, control production cost, can also improve user experience.

[0047] The utility model discloses still provide a kind of cleaning machine, adopt the waterproof structure of electric control handle.
