Description

Technical Field

[0001] The utility model designs a quick-disassembly structure for a water outlet of a faucet. Background Art

[0002] A faucet, also known as a water spout, is a device installed on a pipe to control the on / off switch of water flow. Its structure usually includes components such as a valve core, a handle, a ceramic valve core, and a filter. The valve core of a faucet is used to control the size of the water flow. By rotating the handle, the valve core can be driven to move inside the valve body to switch and adjust the water flow. The filter is generally set at the water outlet of the faucet and is easy to clog and needs to be replaced regularly.

[0003] The water outlet of an existing faucet is usually equipped with a filter screen, which is generally directly embedded in the water outlet. When the filter screen is clogged, it needs to be replaced with special tools, which is very troublesome and consumes a lot of disassembly time, resulting in low maintenance efficiency. Utility Model Content

[0004] The utility model provides a faucet water outlet quick-disassembly structure, which can effectively solve the above problems.

[0005] The utility model is achieved in this way:

[0006] A faucet water outlet quick-release structure, comprising a water outlet pipe fixed to one end of a valve body, a mounting sleeve fixedly arranged on the lower side of one end of the water outlet pipe, a cavity 1 and a cavity 2 respectively arranged on opposite sides of the inner wall of the mounting sleeve from left to right, a filter screen inserted at the lower end of the mounting sleeve, buckles fixedly arranged on opposite sides of the upper end of the filter screen;

[0007] A limiting column is slidably provided on the side wall between the first cavity and the second cavity, which can be snap-fitted with the buckle and fix the filter screen; an L-shaped push rod is slidably provided on the middle and lower part of the inner cavity of the second cavity; a fixing plate located on the same longitudinal axis as the limiting column is fixed on one side of the upper end of the L-shaped push rod; the fixing plate and one end of the limiting column can be magnetically matched;

[0008] The other side of the upper end of the L-shaped push rod is fixedly connected to a top of the cavity through a longitudinal spring.

[0009] As a further improvement, a magnet one is embedded in one end of the fixing plate away from the buckle, and a magnet two that can be magnetically attracted to the magnet one is embedded in one side of the fixing plate facing the limiting column.

[0010] As a further improvement, side plates are fixedly provided on both sides of the limiting column at one end inside the cavity, and transverse springs are fixed between the surfaces of the two side plates and an inner wall of the cavity.

[0011] As a further improvement, under normal conditions, the two transverse springs push one end of the limit column to be located in the middle of the second width of the cavity, and an inclined slope is provided on the lower side of one end of the limit column, and a flat surface is provided on the upper side.

[0012] As a further improvement, an inner ring groove is formed at the lower end of the installation sleeve, a silicone pad is glued and fixed to the lower surface of the inner ring groove, and the silicone pad protrudes from the lower end surface of the installation sleeve and abuts against the filter screen to achieve sealing.

[0013] As a further improvement, rectangular grooves for inserting the buckle are provided on both sides of the silicone pad corresponding to the buckle, and the surface of the rectangular groove abuts against the surface of the buckle.

[0014] The beneficial effects of the utility model are:

[0015] (1) When installing the filter, the buckle moves on the inclined surface of the limit column and pushes the limit column and squeezes the transverse spring. When the upper protrusion of the buckle passes over the limit column, the transverse spring pushes the limit column back to its original position, so that the plane of the buckle protrusion fits with the plane of the limit column, thereby realizing the rapid installation of the filter.

[0016] (2) When removing the filter, the user pushes the L-shaped push rod and the fixing plate upward by hand. During the upward movement of the fixing plate, the second magnet will gradually move to a position relative to the first magnet. Under the attraction of the magnetic force, the first magnet and the second magnet will come into contact with each other, and the limit column and the buckle will separate, thereby separating the filter from the installation sleeve to realize the removal of the filter. The above setting can separate the filter from the installation sleeve with one button, which can realize rapid removal, effectively save a lot of maintenance and replacement time, and improve maintenance efficiency.

[0026] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] The front, back, left, right, top and bottom of the device are Figure 2 is the view base.

[0028] like Figures 1 to 5 As shown, the utility model provides a faucet water outlet quick-release structure, including a water outlet pipe 2 fixed at one end of a valve body 1, and a mounting sleeve 3 for water outlet is fixedly provided on the lower side of one end of the water outlet pipe 2. At the same time, the valve body 1 also includes a valve core and a handle and other devices, which are not the main technologies and will not be described in detail.

[0029] like Figure 2The two opposite sides of the inner wall of the installation sleeve 3 are respectively provided with a rectangular cavity 13 and a rectangular cavity 2 18 from left to right. A side wall is provided between the cavity 13 and the cavity 2 18. The lower end of the installation sleeve 3 is located at the position of the silicone pad 7 and is detachably plugged with a filter screen 5. The filter screen 5 is made of plastic material and has a structural frame matching the structure of the installation sleeve 3. Rectangular buckles 9 are fixed on the opposite sides of the upper end of the filter screen 5. The structure of the buckle 9 (as shown in FIG. Figure 4 As shown, a plane is also provided on the lower side of one end of the clip 9 facing the limiting column 14, and the plane and the plane of the limiting column 14 can fit each other and limit the clip 9. An inner ring groove 6 with a certain depth is opened at the lower end of the mounting sleeve 3, and the lower surface of the inner ring groove 6 is glued and fixed to the upper end of the silicone pad 7. It should be noted that the silicone pad 7 will be squeezed when the filter screen 5 is assembled with the mounting sleeve 3. After the silicone pad 7 is fully installed, it will protrude from the inner wall of the mounting sleeve 3. Therefore, the inner diameter of the silicone pad 7 is smaller than the inner diameter of the mounting sleeve 3.

[0030] like Figure 4 As shown, the lower end surface of the silicone pad 7 protrudes from the lower end surface of the mounting sleeve 3 by 0.5 to 1 mm, and the lower end surface of the silicone pad 7 abuts against the upper end of the filter screen 5 to achieve sealing. Rectangular grooves 8 are provided on both sides corresponding to the silicone pad 7 and the buckle 9. The buckle 9 can be fully inserted into the rectangular groove 8, and the surface of the rectangular groove 8 abuts against the surface of the buckle 9 to achieve sealing.

[0031] like Figure 4 As shown, a circular through hole is provided on the side wall between cavity one 13 and cavity two 18, and a circular limiting column 14 is slidably provided in the through hole and can be snap-connected and fixed with the buckle 9. The filter screen 5 is fixed by the limiting column 14, and an L-shaped push rod 4 is longitudinally slidably provided in the middle and lower part of the inner cavity of cavity two 18. The protruding part of the L-shaped push rod 4 can abut against the lower end surface of the mounting sleeve 3 to achieve limitation and avoid the misalignment between the magnet two 17 and the magnet one 16 at the upper end of the fixing plate 10.

[0032] like Figure 4 As shown, a fixing plate 10 located on the same longitudinal axis as the limiting column 14 is fixed to one side of the upper end of the L-shaped push rod 4, and a space for the limiting column 14 to move is reserved between the surface of the fixing plate 10 and the end face of the limiting column 14, and the length of the space is greater than the length moved when the limiting column 14 is separated from the buckle 9, and a magnet 16 is embedded in the end of the fixing plate 10 away from the buckle 9, and the end face of the magnet 16 protrudes from the surface of the fixing plate 10, and a magnet 2 17 that can be magnetically attracted to the magnet 16 is embedded in the side of the fixing plate 10 facing the limiting column 14.

[0033] Among them, the magnetic attraction of magnet 1 16 and magnet 2 17 on the opposite side is opposite to achieve attraction. At the same time, magnet 1 16 and magnet 2 17 are preferably neodymium magnets, whose strong magnetic force can quickly separate the limit column 14 and the buckle 9. Magnet 1 16 can be attracted and moved by magnet 2 17 within a short distance.

[0034] like Figure 4 As shown, a longitudinal spring 11 is fixed to the upper end of the L-shaped push rod 4 away from the fixed plate 10, and the upper end of the longitudinal spring 11 is fixed to the top of the cavity 13 by AB glue. Under normal conditions, the longitudinal spring 11 stretches the magnet 16 and the magnet 2 17 to be staggered (as shown in FIG. Figure 4 shown).

[0035] like Figure 5 As shown, the limiting column 14 is located at both sides of one end of the cavity 13, and side plates 15 are integrally formed thereon. The surfaces of the two side plates 15 and the inner wall of the cavity 13 are fixed to the two ends of the transverse spring 12 by AB glue. Under normal circumstances, the two transverse springs 12 push one end of the limiting column 14 to be located in the middle of the width of the cavity 2 18, and an inclined slope is provided on the lower side of one end of the limiting column 14, and a plane is provided on the upper side. The two planes described in the text are both set to be smooth to reduce the resistance to the separation of the buckle 9 and the limiting column 14.

[0036] Principle and process of this utility model:

[0037] When installing the filter 5, the user inserts the buckle 9 at the upper end of the filter 5 into the cavity 2 18 and continues to insert and squeeze the silicone pad 7. At this time, the upper end protrusion of the buckle 9 will be on the inclined surface of the limiting column 14 and push the limiting column 14 to move horizontally and squeeze the transverse spring 12 until the upper end protrusion of the buckle 9 passes over the limiting column 14. The reaction force of the transverse spring 12 pushes the limiting column 14 back to its original position. At this time, the user lets go, and the reaction force of the silicone pad 7 drives the buckle 9 to move downward, thereby making the plane of the protrusion of the buckle 9 fit with the plane of the limiting column 14, thereby realizing the installation of the filter 5. The operation is convenient, and the filter 5 only needs to be inserted, which effectively saves the installation time of the filter 5.

[0038] When disassembling the filter 5, the user pushes the L-shaped push rod 4 by hand to move upward in the cavity 13, thereby driving the fixed plate 10 to move upward between the two transverse springs 12 and squeeze the longitudinal spring 11. During the upward movement of the fixed plate 10, the second magnet 17 will gradually move to a position relative to the first magnet 16. At this time, the raised portion of the L-shaped push rod 4 just abuts against the mounting sleeve 3. Under the attraction of the magnetic force, the first magnet 16 will drive the limiting column 14 to move toward the fixed plate 10 until the first magnet 16 and the second magnet 17 are attracted and contacted. At the same time, the limiting column 14 is separated from the buckle 9, thereby separating the filter 5 from the mounting sleeve 3 to realize the disassembly of the filter 5. The above-mentioned setting separates the filter 5 from the mounting sleeve 3 with one button, which can realize rapid disassembly, effectively save a lot of maintenance and replacement time, and improve maintenance efficiency.

[0039] After the filter 5 is removed, the user needs to pinch the L-shaped push rod 4 with his hand and pull it hard. Under the reaction force of the longitudinal spring 11 and the pulling force of the user, the magnet 1 16 slides longitudinally on the surface of the magnet 2 17 and disengages, so that the limit column 14 returns to its original position under the reaction force of the two transverse springs 12, so as to facilitate the installation of the new filter 5.

[0040] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
