DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0037] The embodiment of the present application provides an odor isolation assembly 10, which is used to be installed at the sewage inlet of a urinal, such as Figure 1-Figure 6 As shown, the odor isolation component includes:

[0038] The installation body 1 is configured to be installed in cooperation with the sewage discharge inlet of the urinal;

[0039] The filter cover 2 is provided with a plurality of first filter holes 22. The filter cover 2 is provided to cover the upper end of the installation body 1. The fluid flowing into the first filter holes 22 is discharged from the installation body 1.

[0040] A storage space for accommodating a volatile block 4 is formed between the filter cover 2 and the mounting body 1. A replacement indicator 3 is arranged in the storage space. When the volatile block 4 is installed in the storage space, it is located above the replacement indicator 3. From the top of the filter cover 2 toward the first filter hole 22, the volatile block 4 covers the replacement indicator 3. After the volatile block 4 is volatilized, the replacement indicator 3 is exposed and visible. The volatile block 4 is usually a fragrance block that can volatilize fragrance.

[0041] In the technical solution provided by the embodiment of the present application, when the volatilization block 4 has not completely volatilized, the replacement indicator 3 is blocked, and the replacement indicator 3 cannot be seen from the top of the filter cover 2, indicating that the odor isolation component 10 can continue to be used and its service life has not yet expired. When the volatilization block 4 has completely volatilized, the replacement indicator 3 can be seen from the top of the filter cover 2, indicating that the service life of the odor isolation component 10 has expired. Therefore, the technical solution provided by the embodiment of the present application can easily judge the life of the odor isolation component by replacing the indicator 3, so that the odor isolation component 10 can be replaced in time, or only some components in the odor isolation component 10, such as the one-way membrane sleeve 7, the volatilization block 4, etc., can be replaced.

[0042] After the volatilization of the volatile block 4 is completed, in order to easily identify the replacement indicator 3, the color of the replacement indicator 3 can be set to be different from the color of the volatilization block 4, so that the user can see from the top of the filter cover 2 in a conspicuous way that the volatilization of the volatile block 4 is completed after the color change. For example, the replacement indicator 3 can be set to red, and the volatilization block 3 is yellow. If the yellow color is seen from the first filter hole 22 of the filter cover 2, it means that the volatilization of the volatile block 4 has not been completed. If the red color is seen, it means that the volatilization of the volatile block 4 is completed and the odor isolation component needs to be replaced in time.

[0043] In one embodiment, the replacement indicator 3 is a component installed on the installation body 1, that is, the replacement indicator 3 of a different color from the volatile block 4 is installed at a position below the volatile block 4 of the installation body 1. In another embodiment, the replacement indicator 3 can also be a part of the installation body 1 located below the volatile block 4, and the part can be set to a different color from the volatile block 4.

[0044] In one embodiment, Figure 3-Figure 7 As shown, the installation body 1 includes a mounting sleeve 11, a discharge pipe 13 with a discharge hole 131 located inside the mounting sleeve 11, and an annular plate 12 between the mounting sleeve 11 and the discharge pipe 13, and also includes a support platform 14 covering the upper end of the discharge pipe 13, and the replacement indicator 3 is arranged on the support platform 14. Among them, the mounting sleeve 11 is used to be installed in conjunction with the sewage inlet of the urinal, and a sealing sleeve 5 can be arranged on the outer surface of the mounting sleeve 11 to seal the gap between the mounting sleeve 11 and the sewage inlet.

[0045] Among them, a plurality of second filter holes 142 connected to the discharge hole 131 are arranged on the support platform 14 at intervals along the circumferential direction. The fluid flowing into the containing space from the first filter hole 22 flows to the annular plate 12, enters the second filter hole 142 from the annular plate 12, and then flows into the discharge hole 131, and then is discharged downward from the discharge hole 131.

[0046] like Figure 4 As shown, the support platform 14 is a cap-shaped structure having a top wall and a peripheral wall surrounding the top wall. The replacement indicator 3 is arranged on the top wall of the support platform 14. A plurality of second filter holes 142 are arranged on the peripheral wall of the support platform 14 at intervals along the circumferential direction.

[0047] In one example, Figure 3 and Figure 4 As shown, the upper surface of the annular plate 12 forms a conical surface, the conical surface is gradually reduced in cross section from top to bottom, and the second filter hole 142 extends downward to the bottom end of the conical surface. In this way, the fluid falling on the annular plate 12 can flow smoothly and quickly downward along the conical surface to the second filter hole 142, and then enter the discharge hole 131 from the second filter hole 142.

[0048] In one example, at least one first mounting post 21 is provided on the filter cover 2, and at least one first matching hole 1411 is provided on the support platform 14. The filter cover 2 is installed on the support platform 14 by interference fit between the first mounting post 21 and the first matching hole 1411, and the first mounting post 21 and the first matching hole 1411 are matched to be arranged so that the first mounting post 21 can adjust its position up and down, that is, when a certain amount of force is applied to press the first mounting post 21 downward or pull the first mounting post 21 upward, the first mounting post 21 can move relative to the first matching hole 1411 to adjust its position.

[0049] By adjusting the first mounting post 21 to achieve the upper and lower position adjustment of the filter cover 2, when the odor isolation assembly 10 is installed on the ceramic body of the urinal, the gap between the filter cover 2 and the ceramic body will not be too large due to the large tolerance of the ceramic body and other problems, thereby preventing larger foreign objects (such as cigarette butts, hair, etc.) from entering the interior of the odor isolation assembly. At the same time, the interference fit installation method can make the filter cover 2 have a certain fixing effect, preventing the filter cover 2 from moving when the urine flow is large during use, resulting in the liquid being unable to be filtered through the filter cover 2.

[0050] exist Figure 3-Figure 5In the example shown, the first mounting column 21 is arranged at the center of the filter cover 2 and extends downward, and the first matching hole 1411 penetrating the support platform 14 is arranged at the center of the support platform 14. A protruding protrusion 141 is arranged at the center of the support platform 14 on the side facing the discharge hole 131, and the first matching hole 1411 penetrates the protrusion 141. Only at the end of the protrusion 141, the first matching hole 1411 is interference-fitted with the first mounting column 21, so that the first mounting column 21 can be easily adjusted up and down. In addition, a first center hole 31 is arranged on the replacement indicator 3, and a second center hole 41 is arranged on the volatile block 4. When installing the filter cover 2, the first mounting column 21 of the filter cover 2 is inserted into the first matching hole 1411 of the support platform 14 after passing through the second center hole 41 of the volatile block 4 and the first center hole 31 of the replacement indicator 3 in sequence, and then adjusted up and down according to the sewage inlet of the urinal.

[0051] It is understandable that the filter cover 2 can also be installed on the installation body 1 in other ways, such as by snap-fitting.

[0052] In one example, the replacement indicator 3 is mounted on the support platform 14. At least one second mounting column 32 may be provided on one of the replacement indicator 3 and the support platform 14, and at least one second matching hole 144 may be provided on the other, and the replacement indicator 3 is mounted on the support platform 14 through interference fit between the second mounting column 32 and the second matching hole 144.

[0053] like Figure 6 As shown, two second mounting posts 32 are provided on the replacement indicator 3, and two second matching holes 144 corresponding to the second mounting posts 32 are provided on the support platform 14. The replacement indicator 3 is installed by inserting the two second mounting posts 32 into the corresponding second matching holes 144 respectively.

[0054] In one example, Figure 4 and Figure 5 As shown, the top of the support platform 14 is provided with a first vent hole 143 connected to the discharge hole 131, and the replacement indicator 3 is provided with a plurality of second vent holes 33 corresponding to the first vent holes 143. The first vent holes 143 and the second vent holes 33 are provided to facilitate ventilation of the volatile block 4 so as to volatilize.

[0055] Figure 4 and Figure 5 In the example shown, a second filter hole 142 extending from top to bottom is provided on the peripheral wall of the support platform 14, and a third ventilation hole 34 can be further provided on the replacement indicator 3 at a position corresponding to the second filter hole 142. The third ventilation hole 34 corresponds to the position of the second filter hole 142, and can also facilitate the ventilation of the volatile block 4.

[0056] In one embodiment, Figure 3-Figure 7 As shown, the diaphragm assembly further includes a one-way membrane sleeve 7 and a lower fixed sleeve 6; wherein the one-way membrane sleeve 7 includes a mounting sleeve portion 71 sleeved on the outside of the discharge pipe 13 and a flat sleeve portion 72 located below the mounting sleeve portion 71, that is, the one-way membrane sleeve 7 is a duckbill-shaped one-way membrane sleeve. The lower fixed sleeve 6 is configured to be connected to the installation body 1 and has a clamping sleeve 63 located on the outside of the mounting sleeve portion 71, and the mounting sleeve portion 71 is clamped between the clamping sleeve 63 and the discharge pipe 13; wherein, as shown Figure 3 As shown, the outer side of the mounting sleeve 71 is formed in a threaded shape, which can facilitate the clamping sleeve 63 of the lower fixed sleeve 6 and the discharge pipe 13 to squeeze and deform the mounting sleeve 71 so that it can be firmly clamped and fixed between the clamping sleeve 63 and the discharge pipe 13, and can also achieve sealing, so that the fluid discharged from the discharge pipe 13 flows into the one-way membrane sleeve 7 without leaking from the upper end of the mounting sleeve 71.

[0057] The flat sleeve 72 has a closed state and an open state. When fluid flows out of the discharge pipe 31, the fluid stretches the flat sleeve 31 to convert the flat sleeve 31 from the closed state to the open state. When no fluid flows out, the flat sleeve 31 is in a closed state to prevent odor.

[0058] In one example, if Figure 7 As shown, the lower fixed sleeve 6 also includes a main sleeve body 64 located below the clamping sleeve 63. The main sleeve body 64 has a flat cavity 641 for accommodating the flat sleeve portion 72. The flat cavity 641 can limit the flat sleeve portion 72 and prevent the flat sleeve portion 72 from being pushed to fold upward when the gas pressure below the odor isolation component is high, thereby affecting the flow and downward discharge.

[0059] In addition, in order to realize the fixed connection between the lower fixing sleeve 6 and the installation body 1, the lower fixing sleeve 6 also includes a fitting sleeve 61 and a fitting plate 62. The fitting sleeve 61 fits on the radial inner surface of the installation sleeve 11 of the installation body 1, the fitting plate 62 fits on the lower surface of the annular plate 12 of the installation body 1, and the top of the clamping sleeve 63 is connected to the fitting plate 62. A clamping structure is provided between the outer side of the fitting sleeve 61 and the installation sleeve 11, and the lower fixing sleeve 6 and the installation body 1 are fixed together by clamping.

[0060] During installation, first, put the installation sleeve part 71 of the one-way membrane sleeve 7 on the discharge pipe 13 of the installation body 1, then put the clamping sleeve 63 of the lower fixed sleeve 6 on the discharge pipe 13, and push the lower fixed sleeve 6 toward the installation body 1, so that the fitting sleeve 61 of the lower fixed sleeve 6 fits on the inner side of the installation sleeve 11 and the fitting plate 62 fits on the lower surface of the annular plate 12, and the right side can realize the clamping fixation of the fitting sleeve 61 and the installation sleeve 11, as well as the clamping fixation of the installation sleeve part 71 of the one-way membrane sleeve 7.

[0061] The embodiment of the present application also provides a urinal, such as Figure 8-Figure 10 As shown, the urinal includes a urinal body 20 and the odor isolation assembly 10 as described above, and the odor isolation assembly 10 is installed at a sewage inlet 21 provided on the urinal body 20 .

[0062] The urinal provided in the embodiment of the present application can observe whether the volatile block 4 has evaporated through the filter cover 2 of the odor isolation assembly 10, and the odor isolation assembly 10 or the parts in the odor isolation assembly 10 can be replaced in time, thereby better maintaining the urinal.

[0063] like Fig. 9 In the example shown, a drainage pipe 22 is provided at the sewage inlet 21 of the urinal, and a connecting pipe 30 (which is connected to the building pipe) is provided at the end of the drainage pipe 22. The fluid discharged from the odor isolation assembly 10 enters the drainage pipe 22 and is then discharged from the connecting pipe 30.

[0064] Fig.10 The solid arrows in the figure show the state of urine being discharged from the upper part through the odor-isolating component 10, and the hollow arrows show the state of gas in the space below the odor-isolating component 10 flowing upward and hitting the odor-isolating component 10 and returning. Fig.10 It can be seen that the odor isolation component 10 can effectively prevent the discharge of odor.
