Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent toilet connectors, and in particular relates to a locking device and an application thereof. Background Art

[0002] Smart toilet seats have many functions such as seat heating, warm water flushing, hot air drying, etc. As people's living standards improve, more and more families choose smart toilet seats instead of traditional toilet seats.

[0003] Smart toilet lids on the market typically consist of a cover assembly, a functional mechanism, and an operating mechanism. The cover assembly is typically located at the front of the toilet bowl, with the rear end connected to the functional mechanism. To meet various requirements, the functional mechanism is often equipped with components such as a heating element, a flushing element, or a hot air element. As a result, the functional mechanism is often large and needs to be fixed to the toilet bowl, with minimal distance from the water tank or wall at the rear end of the toilet bowl. Furthermore, due to the movable connection, there is a noticeable gap between the cover assembly and the functional mechanism. This allows only the cover assembly to be moved during use, avoiding the need to lift the bulky and heavy rear functional mechanism, thus saving time and effort.

[0004] However, this structure and movement create cleaning challenges. Existing easy-to-clean smart toilet lids typically focus on cleaning the cover assembly, the toilet seat itself, and the hinged connection between the cover assembly and the rear assembly. The rear functional mechanism, however, is difficult to clean due to its fixed position. However, during use, the gaps and slots in the toilet seat, where the functional mechanism is permanently fixed, are easily contaminated, making them difficult to clean and prone to bacterial growth. This can cause odors in the bathroom and harm human health.

[0005] If some connecting rod devices are used to lift or flip the functional mechanism at the rear end of the toilet, the bottom can be cleaned, but a certain locking device is required to fix it during the process, otherwise the functional mechanism is likely to fall and be damaged. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a locking device and its application, which solves the problem of locking the position of the functional mechanism when it is lifted or flipped by a connecting rod in the above background technology.

[0007] One of the technical solutions adopted by the present invention to solve its technical problem is: providing a locking device, including a bracket, a support block, a travel limit block and a locking rod;

[0008] The support block is pivotally connected to the bracket, and a first channel is provided between the support block and the bracket; a limiting groove is provided on the support block, and the limiting groove is located on the side wall of the support block close to the bracket, and a second channel is formed above the limiting groove;

[0009] The travel limit block is pivotally connected to the support block and is used to guide the locking rod into the second channel or the first channel to achieve locking and resetting of the locking rod;

[0010] The locking rod is arranged between the support block and the bracket;

[0011] When the locking rod is located above the limit slot and below the travel limit block, the travel limit block is in a flipping state and the second channel is opened; in the locked state, the locking rod is located in the limit slot; when the locking rod is located above the travel limit block, the travel limit block is in a falling state and the second channel is closed; in the reset state, the locking rod is located in the first channel.

[0012] In a preferred embodiment of the present invention, the support block is provided with a limiting step, and the limiting step is arranged below the travel limiting block.

[0013] In a preferred embodiment of the present invention, the bottom of the support block is pivotally connected to the bracket, and the bracket is provided with an abutting inclined surface on a side facing the support block.

[0014] In a preferred embodiment of the present invention, the support block is provided with an inclined wall adapted to the abutting inclined surface, and the bottom of the inclined wall is the limiting groove.

[0015] In a preferred embodiment of the present invention, the free end of the travel limit block comprises a driving surface and a guide surface, and the angle between the driving surface and the guide surface is acute. When the locking rod falls, the distance between the free end of the travel limit block and the bracket is at least large enough to allow the locking rod to pass through.

[0016] In a preferred embodiment of the present invention, a torsion spring is provided between the support block and the bracket, and between the travel limit block and the support block.

[0017] The present invention further provides a connecting rod assembly, comprising a connecting rod and the above-mentioned locking device, wherein the locking device is arranged beside the connecting rod, and the support rod is installed on the connecting rod.

[0018] In a preferred embodiment of the present invention, it comprises two sets of connecting rods arranged in parallel, and the locking device is arranged between the two sets of connecting rods.

[0019] In a preferred embodiment of the present invention, a fixing plate is further included, and the connecting rod and the locking device are installed on the fixing plate.

[0020] The present invention also provides a flip-clean smart toilet cover, which includes a cover plate assembly, a functional mechanism, and the above-mentioned connecting rod assembly, wherein the connecting rod assembly is used to connect the functional mechanism and the toilet seat and realize the flipping of the functional mechanism.

[0021] Compared with the background technology, this technical solution has the following advantages:

[0022] 1. The locking device of the present invention utilizes the positions of the support block and the travel limit block to achieve locking and resetting of the locking rod. The second channel is opened by moving the locking rod upward, and then the locking rod is moved downward under the action of gravity, causing the travel limit block to fall back under the action of gravity, thereby closing the second channel. This is convenient and quick.

[0023] 2. The locking device of the present invention has torsion springs between the support block and the bracket, and between the travel limit block and the support block to ensure the accuracy of travel control;

[0024] 3. The locking device of the present invention, with its stopper step on the support block and the free end of the travel stopper, ensures that the travel stopper can smoothly rotate without excessive rotation when the locking rod moves upward, and also ensures that the locking rod smoothly returns to the first channel after the travel stopper returns.

[0025] 4. The connecting rod assembly of the present invention can be locked and released by repeatedly lifting the connecting rod, with a single action, thus avoiding operational errors;

[0026] 5. The present invention applies the above-mentioned connecting rod assembly and locking device to the smart toilet cover, realizing the bottom of the functional mechanism flipping and lifting to obtain a clean space, forming a stable structure to ensure that the functional mechanism does not fall during the cleaning process, freeing hands and facilitating operation;

[0027] 6. The intelligent toilet cover, connecting rod assembly and locking device of the present invention are all fixed to the rear end wall of the toilet through a fixing plate, which reduces the occupied volume and enables the connecting rod assembly and functional mechanism to still be normally installed at the rear end of the toilet. The position of the support rod can be adjusted according to the actual connecting rod, and has a wide range of product adaptability. BRIEF DESCRIPTION OF THE DRAWINGS

They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0042] Example 1

[0043] The present embodiment provides a flip-up cleaning smart toilet cover, which includes a cover plate assembly 61, a functional mechanism 62, and a connecting rod assembly 63. The connecting rod assembly 63 is used to connect the functional mechanism 62 and the toilet seat 6 and realize the flipping of the functional mechanism 62.

[0044] The connecting rod assembly 63 of this embodiment includes two parallel connecting rods and a locking device 64 disposed between the two connecting rods. It also includes a fixing plate 65 to which the connecting rods and locking device 64 are mounted. The fixing plate 65 is fixed to the rear wall of the toilet bowl, reducing the occupied volume and allowing the connecting rod assembly 63 and functional mechanism 62 to be properly installed at the rear end of the toilet bowl.

[0045] The locking device 64 of this embodiment includes a bracket 1, a support block 3, a travel limit block 2 and a locking rod 5;

[0046] The support block 3 is pivotally connected to the bracket 1, and a first channel 11 is defined between the support block 3 and the bracket 1; the support block 3 defines a limiting groove 31, which is located on the side wall of the support block 3 close to the bracket 1, and a second channel 12 is formed above the limiting groove 31;

[0047] The travel limit block 2 is pivotally connected to the support block 3 and is used to guide the locking rod 5 into the second channel 12 or the first channel 11 to achieve locking and resetting of the locking rod 5;

[0048] The locking rod 5 is provided between the support block 3 and the bracket 1;

[0049] When the locking rod 5 is located above the limit slot 31 and below the travel limit block 2, the travel limit block 2 is in a flipped state and the second channel 12 is opened; in the locked state, the locking rod 5 is located in the limit slot 31; when the locking rod 5 is located above the travel limit block 2, the travel limit block 2 is in a fallen state and the second channel 12 is closed; in the reset state, the locking rod 5 is located in the first channel 11.

[0050] In this embodiment, the support block 3 is provided with a limiting step 33 , and the limiting step 33 is provided below the travel limiting block 2 .

[0051] The bottom of the support block 3 is pivotally connected to the bracket 1. The bracket 1 has an abutting inclined surface 13 on the side facing the support block 3. The support block 3 has an inclined wall 32 that matches the abutting inclined surface 13. The bottom of the inclined wall 32 forms the limiting groove 31. The opening of the limiting groove 31 is oriented obliquely upward to ensure that the locking rod 5 can smoothly fall into the limiting groove 31 when it falls.

[0052] The free end of the travel limiter 2 is formed by a driving surface 21 and a guide surface 22, which form an acute angle. In this embodiment, the driving surface 21 is the lower bottom surface, and the locking rod 5 abuts the driving surface 21 to cause the travel limiter 2 to flip upward. The guide surface 22 facilitates the downward movement of the locking rod 5 into the first channel 11.

[0053] Torsion springs 4 are provided between the support block 3 and the bracket 1, and between the travel limiter 2 and the support block 3. In this embodiment, when the support block 3 and the travel limiter 2 are tilted, the torsion springs 4 store angular energy. This, combined with the slanted wall 32 of the support block 3 and the drive surface 21, prevents the locking rod 5 from being dislodged from the bracket 1. When the locking rod 5 is reset, the torsion springs 4 release the angular energy, ensuring that the device smoothly returns to its initial position.

[0054] like Figure 8In the initial state in a, the locking rod 5 is located at the bottom of the first channel 11 between the bracket 1 and the support block 3. When the toilet cover is operated to make the cleaning mechanism drive the connecting rod to flip up, the locking rod 5 moves upward; when the locking rod 5 moves upward, it hits the driving surface 21 of the travel limit block 2, and the travel limit block 2 begins to flip. When the locking rod 5 moves upward to above the limit groove 31 as in the position in b, the second channel 12 is opened and the limit groove 31 is exposed; at this time, the force is relaxed, and under the action of gravity, the locking rod 5 falls into the limit groove 31 as in c, reaching a locked state, whereby the connecting rod cannot continue to move downward, and the cleaning mechanism maintains the flipped state;

[0055] like Figure 9 After cleaning is completed, the toilet cover is operated again to make the cleaning mechanism drive the connecting rod to flip up, and the locking rod 5 moves upward; when the locking rod 5 moves upward to above the limit groove 31 as in position b, it is higher than the travel limit block 2, the travel limit block 2 rotates and resets, and the second channel 12 is closed, as shown in c; the force is relaxed, and under the action of gravity, the locking rod 5 falls, and enters the first channel 11 under the action of the guide surface 22, returning to the initial state, as shown in d.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
