Description

Technical Field

[0001] The present invention relates to a toilet companion, in particular to a toilet companion that is convenient for maintenance. Background Art

[0002] A toilet companion is a spray gun rinser installed on the side of a toilet and used for cleaning. It includes a spray gun and a three-way pipe, and the spray gun is connected to the three-way pipe through a hose.

[0003] However, for the existing toilet companions to prevent water overflow, a push-type valve core is generally installed in the three-way pipe. When the spray gun is inserted into the three-way pipe, the water path is automatically cut off, and when the spray gun is removed, the water path is restored. When replacing the spray gun or hose for this kind of toilet companion with such a structure, the three-way pipe is always in a water supply state, which is not convenient for maintenance.

[0004] For example, a new type of spray gun bracket disclosed in the patent with the publication number CN209174227U includes a bracket body, an automatic switch, and a spray gun. After the spray gun is inserted into the socket, the side wall of the spray gun presses against the rod body of the water stop ejector rod, causing it to move towards the water guide cavity. At the same time, the third pressing part presses the second pressing part until the first pressing part presses against the water outlet hole to block the water outlet hole, and the spray gun stops supplying water. In the above patent, there is no locking structure on the bracket body. When the spray gun or hose needs to be replaced, it is necessary to manually hold the water stop ejector rod all the time, which is not convenient for maintenance.

[0005] Therefore, there is an urgent need for a toilet companion that is convenient for maintenance to facilitate the replacement of the spray gun or hose in the later stage. Summary of the Invention

Detailed implementation manners

[0026] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it cannot be understood as a limitation on the protection scope of the present invention.

[0027] In the description of the present invention, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc., is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0029] Refer to Figures 1 to 6 , a toilet companion convenient for maintenance, including a main body 1 and a spray gun 2. The spray gun 2 is in waterway communication with the main body 1 through a hose 3. A push-type valve core assembly is installed in the main body 1. The valve core assembly (push-type valve core) includes a valve body 51. The valve body 51 has a compressed state and an expanded state. When in the compressed state, the waterway of the valve core assembly is closed. When in the expanded state, the waterway of the valve core assembly is opened and communicated. A locking assembly 4 is installed on the main body 1. The locking assembly 4 includes a bolt 42. The lower end of the bolt 42 extends into the main body 1. When the valve body 51 is in the compressed state, the bolt 42 can be further pressed down to clamp the valve body 51, thereby clamping the valve body 51 and restricting the valve body 51 from rebounding, so that the valve core assembly is in a normally closed state. There is no need to keep manually pressing the valve body 51 to close the water outlet all the time. After the valve body 51 is clamped, the spray gun 2 and the hose 3 can be replaced, which is convenient for maintenance.

[0030] In some embodiments, the main body 1 includes a pipe portion 11 and a plugging portion 12. A plugging hole 121 for plugging the spray gun 2 is provided on the plugging portion 12, and a through hole 122 is provided at the intersection of the pipe portion 11 and the plugging portion 12; the valve core assembly further includes a top cover 52 installed at the end of the valve body 51 (the end close to the plugging hole 121). The top cover 52 moves synchronously with the valve body 51. The top cover 52 can pass through the through hole 122 and partially enter the plugging hole 121; the top cover 52 has an annular portion 522, and the diameter of the annular portion 522 is greater than the diameter of the through hole 122. When the valve body 51 is in the unfolded state, the annular portion 522 abuts against the rear side of the through hole 122. The annular portion 522 is slidably connected to the inner wall of the pipe portion 11. A first locking hole 524 is provided on the annular portion 522, and a second locking hole 112 is provided on the side wall of the pipe portion 11. The locking assembly 4 is installed on the second locking hole 112; when the valve body 51 is in the compressed state (or compressed to a certain position), the first locking hole 524 and the second locking hole 112 are located on the same circular line. The bolt 42 can sequentially pass through the first locking hole 524 and the second locking hole 112. The bolt 42 indirectly blocks the movement of the valve body 51 by clamping on the top cover 52. At this time, the main body 1 is in the locked state (the valve body 51 is in the compressed state), and vice versa is the unlocked state (the valve body 51 is in the unfolded state).

[0031] In a preferred embodiment, an installation groove 111 is provided on the side wall of the pipe portion 11. The second locking hole 112 is located at the bottom surface of the installation groove 111, and the locking assembly 4 is installed in the installation groove 111; the locking assembly 4 further includes a fixed seat 41 and a spring 43. Internal threads are provided on the inner side wall of the installation groove 111, and external threads are provided on the outer side wall of the fixed seat 41. The fixed seat 41 is screwed into the installation groove 111; a first limiting portion 411 is provided at the upper end of the fixed seat 41, and a second limiting portion 421 is provided at the upper end of the bolt 42. The second limiting portion 421 abuts against the lower side of the first limiting portion 411 through the spring 43. Two ends of the spring 43 respectively abut against the second limiting portion 421 and the bottom surface of the installation groove 111. The spring 43 is used to rebound the bolt 42. The lower end of the bolt 42 passes through the second locking hole 112 and partially inserts into the main body 1; when the main body 1 is in the locked state, the bolt 42 is strung through the first locking hole 524 and the second locking hole 112. The valve body 51 has a tendency to move forward. The front and rear sides of the bolt 42 are respectively clamped (clamped) on the front side wall of the second locking hole 112 and the rear side wall of the first locking hole 524, that is, the bolt 42 is clamped and held together by the clamping and frictional forces of the two locking holes.

[0032] In a preferred embodiment, when the main body 1 is in the locked state, the top cover 52 is still partially located in the insertion hole 121. After the spray gun 2 is inserted, the spray gun 2 can press the top cover 52, causing the top cover 52 to move backward. The first locking hole 524 and the second locking hole 112 cancel the clamping of the latch 42, and the latch 42 rebounds under the action of the spring 43, eliminating the need to manually press the top cover 52, which further facilitates later maintenance.

[0033] Specifically, in some embodiments, the above-mentioned locking assembly 4 can be replaced with a ratchet structure such as that of a ballpoint pen tip, which realizes clamping the latch 42 on the body of the locking assembly 4, so that the latch 42 always passes through the first locking hole 524 and the second locking hole 112. After maintenance, the latch 42 is pressed again to make it rebound. However, the ratchet structure of the ballpoint pen tip is relatively complex and costly, while the locking assembly 4 of the present invention is relatively simple and feasible in structure and has a lower cost.

[0034] In a preferred embodiment, a strip-shaped groove 523 is provided on the annular portion 522. The length direction of the strip-shaped groove 523 is parallel to the telescopic direction of the valve body 51. The first locking hole 524 is provided in the strip-shaped groove 523, and the lower end of the latch 42 is always inserted in the strip-shaped groove 523. The strip-shaped groove 523 has a limiting and guiding effect on the latch 42, enabling the latch 42 to be better guided onto the first locking hole 524.

[0035] In a preferred embodiment, a first annular inclined surface 422 is provided at the lower end of the latch 42, and the lower end of the first annular inclined surface 422 inclines inward; a second annular inclined surface 5241 corresponding to the first annular inclined surface 422 is provided at the upper end of the first locking hole 524, and the lower end of the second annular inclined surface 5241 inclines inward. By providing the inclined surfaces, the latch 42 can be better inserted into the first locking hole 524.

[0036] In a preferred embodiment, the top cover 52 further includes a spherical portion 521, and the spherical portion 521 is provided at the front end of the top cover 52, that is, the portion of the top cover 52 extending into the insertion hole 121 is an arc surface structure, enabling the spray gun 2 to better drive the top cover 52.

[0037] In a preferred embodiment, the main body 1 is installed on the wall surface, and the locking assembly 4 is installed on the side wall of the main body 1 facing the wall surface, that is, the common surface facing away from the user, making the appearance more concise.

[0038] A maintenance method for a toilet companion. When the main body 1 is in the locked state, the top cover 52 is completely located inside the main body 1. The maintenance steps are as follows: Remove the spray gun 2, manually press the top cover 52 and press the plug pin 42. The valve body 51 does not rebound. At this time, the valve core assembly is in the normally closed state and the waterway is closed. Then replace the spray gun 2 or the hose 3. After replacement, manually press the top cover 52 to make the plug pin 42 rebound and reset, and the waterway of the valve core assembly is opened. Finally, insert the spray gun 2 into the insertion hole 121.

[0039] A maintenance method for a toilet companion. When the main body 1 is in the locked state, the top cover 52 is still partially located inside the insertion hole 121. The maintenance steps are as follows: Remove the spray gun 2, manually press the top cover 52 and press the plug pin 42. The valve body 51 does not rebound. At this time, the valve core assembly is in the normally closed state and the waterway is closed. Then replace the spray gun 2 or the hose 3. After replacement, insert the spray gun 2 into the insertion hole 121. During the insertion process, the spray gun 2 compresses the top cover 52, and the top cover 52 drives the valve body 51 to move backward. The first locking hole 524 and the second locking hole 112 cancel the clamping of the plug pin 42, and the plug pin 42 rebounds under the action of the spring 43, and the plug pin 42 automatically rebounds and resets. There is no need to press the top cover 52 anymore, which further facilitates later maintenance.

[0040] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
