Description

Technical Field

[0001] This utility model relates to the field of toilet accessories technology, and in particular to a toilet deodorizing device and its ventilation connection component. Background Technology

[0002] In related technologies, to reduce odors produced during toilet use, ventilation equipment, such as exhaust fans, is usually installed in the bathroom window or ceiling to remove the odors. However, before the ventilation equipment can completely remove the odors, the smell may have already spread throughout the bathroom, so this method of eliminating bathroom odors usually does not provide satisfactory results.

[0003] In other toilet deodorization solutions, such as those disclosed in patent CN220459269U, a ventilated toilet seat is installed on top of the toilet bowl. An exhaust fan draws air from the toilet and then releases it outdoors. This solution is generally suitable for toilets installed near exterior walls, making the installation environment more limited. Utility Model Content

[0029] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0030] refer to Figure 1 , Figure 2 and Figure 3 This application discloses a ventilated connection assembly 100, which can be used in a toilet deodorizing device 10. The ventilated connection assembly 100 includes a connecting portion 110 and a base 120, and is combined with... Figure 4 The connecting portion 110 extends along a first direction and has a first air passage 110a. The connecting portion 110 is used to connect to the venting and draining component 200 of the toilet deodorizing device 10. The venting and draining component 200 is correspondingly arranged with the toilet drain outlet 30c of the toilet 30, so that the first air passage 110a is ultimately connected to the drain channel 40a below the toilet 30. The base 120 extends along a second direction and has a second air passage 120a. The second direction is set at an angle to the first direction, and the second air passage 120a is connected to the first air passage 110a. In some embodiments, the first direction and the second direction are perpendicular, i.e., they form a 90-degree angle. For example, after the venting connection assembly 100 is assembled with the toilet 30, the connecting portion 110 extends in the horizontal direction, while the base 120 extends in the vertical direction. In other embodiments, the first direction and the second direction can form other angles, such as acute angles.

[0031] Continue to refer to Figure 2The outer contour of the cross-section of the base 120 is non-circular. The base 120 is used to pass through the toilet mounting hole 30a of the toilet 30, and the second air duct 120a is used to connect to the fan assembly 500 of the toilet deodorizing device 10. The toilet mounting hole 30a is generally used to pass through fasteners such as bolts to reliably fix the toilet 30 to the floor. Exemplarily, the cross-section of the toilet mounting hole 30a is racetrack-shaped, that is, the shape formed by two parallel lines connecting two arcs. The outer contour of the cross-section of the base 120 can match the cross-sectional contour of the toilet mounting hole 30a. For example, the outer contour of the cross-section of the base 120 is racetrack-shaped, and the base 120 can have a uniform wall thickness, that is, the inner contour of the cross-section of the base 120 can also be racetrack-shaped and similar to the cross-sectional contour of the toilet mounting hole 30a, or in other words, the inner contour of the cross-section of the base 120 matches the cross-sectional contour of the toilet mounting hole 30a. This structural design allows the cross-sectional dimensions of the first air passage 110a to be set as large as possible, thereby reducing air resistance and improving the deodorization efficiency of the toilet deodorization device 10.

[0032] In other embodiments, the outer contour of the cross-section of the base 120 can also be other non-circular shapes, such as rectangles, rounded rectangles, or ellipses, so that the cross-sectional size of the first air passage 110a can be set as large as possible. Taking the outer contour of the cross-section of the base 120 as a rectangle, the four corners of the rectangle can be connected to the wall of the toilet mounting hole 30a, thereby setting the cross-sectional size of the first air passage 110a as large as possible.

[0033] The blower assembly 500 of the toilet deodorizing device 10 is fixed in position relative to the toilet bowl 31 of the toilet 30 and may include at least one fan 510. The second air duct 120a is connected to the blower assembly 500 and is combined with... Figure 5 The toilet deodorizing device 10 may also include an air intake 600. The fan assembly 500 is connected to the toilet bowl 31 through the air intake 600. The position of the air intake 600 and the toilet bowl 31 is relatively fixed, for example, it is fixed to the top of the toilet bowl 31 through the seat mounting hole 30b on the toilet bowl 31. The air intake 600 is hollow and has an air intake 601 connected to the inside of the toilet bowl 31. The air intake 600 achieves communication between the air intake 601 and the inside of the fan assembly 500 through the internal hollow channel, so as to draw in odorous air from inside and around the toilet bowl 31 through the air intake 601, guide the air to flow into the inside of the fan assembly 500, and then flow sequentially through the second air passage 120a, the first air passage 110a and the venting and draining device 200, and finally discharge into the sewage passage 40a.

[0034] Of course, in some embodiments, the fan assembly 500 may be equipped with a one-way valve to ensure unidirectional gas flow and prevent odorous gases in the sewage discharge channel 40a from flowing back into the bathroom via the fan assembly 500 and the external pipe 700. In some embodiments, the suction element 600 or the fan assembly 500 may be constructed as part of the toilet seat. Of course, in some embodiments, the toilet seat may also integrate all or part of the components and functions of the suction element 600 or the fan assembly 500.

[0035] Continue to refer to Figure 2 In some embodiments, a reinforcing member 130 is provided at the connection between the base 120 and the connecting portion 110, and the reinforcing member 130 is integrally formed with the base 120 and the connecting portion 110. Figure 2 In the illustrated embodiment, the reinforcing body 130 slightly protrudes from the top surface of the connecting portion 110 and surrounds the base 120 in a complete or partial circle to enhance the structural strength of the connection between the base 120 and the connecting portion 110. This prevents the connecting portion 110 from breaking off from the base 120 due to stress caused by the assembly gap between the venting and draining component 200, the venting connection assembly 100, and the toilet 30 after the base 120 is assembled into the toilet mounting hole 30a. Of course, in other embodiments, the reinforcing body 130 does not necessarily need to be continuously surrounding the base 120; for example, two or more reinforcing bodies 130 can be provided at circumferential intervals around the base 120.

[0036] In some embodiments, the vent connection assembly 100 may further include a foot 140, which is disposed on the side of the connection portion 110 opposite to the base 120. The axial direction of the foot 140 may be parallel to the axial direction of the base 120, i.e., the second direction, and the length of the foot 140 in the second direction may vary depending on the installation environment requirements. The foot 140 may be installed inside the toilet flange of the toilet 30, thereby reinforcing the fixation of the toilet 30 to the ground or floor.

[0037] A reinforcing member 130 may also be provided at the connection between the foot 140 and the connecting part 110, such as Figure 4 As shown, the reinforcing body 130 is integrally formed with the foot 140 and the connecting part 110. The reinforcing body 130 slightly protrudes from the bottom surface of the connecting part 110 and surrounds the foot 140 in a complete or partial circle to enhance the structural strength of the connection between the foot 140 and the connecting part 110. This prevents the foot 140 from breaking off from the connecting part 110 due to stress caused by the assembly gap between the venting and draining component 200, the venting connection assembly 100, and the toilet 30 after the base 120 is assembled into the toilet mounting hole 30a. In other embodiments, the reinforcing body 130 does not necessarily need to be continuously surrounding the foot 140; for example, two or more reinforcing bodies 130 can be provided at circumferential intervals around the foot 140.

[0038] In some embodiments, the foot 140 can be assembled and fixed to the connecting part 110, for example, by means of threads or interference fit. In this embodiment, the foot 140 can be made of a different material than the connecting part 110, for example, a material with higher structural strength than the connecting part 110. By assembling and fixing it to the connecting part 110, the molding difficulty of the vent connection assembly 100 is reduced, and while reinforcing the toilet 30 on the ground or floor, the foot 140 is prevented from deforming, ensuring the reliability of the connection. Of course, the foot 140 can also be omitted.

[0039] Continue to refer to Figure 2 and combined Figure 4 , Figure 5 The venting connection assembly 100 may include a fastener 150 connected to the base 120 to securely connect the venting connection assembly 100 to the toilet 30. Exemplarily, the fastener 150 includes a converter 151 and a fastener 153, the converter 151 being detachably connected to the base 120, and the fastener 153 being connected to the converter 151 to reinforce the fixed connection between the toilet 30 and the floor via the venting connection assembly 100. Figure 2 In the embodiment shown, the outer contour of the cross-section of the base 120 is racetrack-shaped, and a first biting body 121 can be distributed on its outer side along the second direction. The conversion body 151 has an opening 151a in the circumferential direction, and the inner wall of the conversion body 151 has a second biting body 1511 for biting with the first biting body 121.

[0040] The first engaging body 121 may include a plurality of protruding tooth-like structures spaced apart on the outer side of the base 120, and the second engaging body 1511 on the inner wall of the converter 151 may also include a plurality of protruding tooth-like structures spaced apart. During the assembly of the venting connection assembly 100 and the toilet 30, after the base 120 passes through the toilet mounting hole 30a, it extends out from the side of the toilet mounting hole 30a away from the sewage channel 40a. The converter 151 can be fitted into the base 120 along the first direction. The tooth-like structures of the first engaging body 121 and the second engaging body 1511 engage with each other, so as to achieve a general engagement between the first engaging body 121 and the second engaging body 1511. After the fastener 153 is connected to the converter 151, it can prevent the converter 151 from moving easily along the second direction, so as to ensure the reliability of the venting connection assembly 100 in the toilet 30.

[0041] For example, the internal thread of the fastener 153 engages with the external thread of the converter 151. In other words, the outer contour of the cross-section of the converter 151 can be arc-shaped, with threads on the outer side extending helically in the second direction, but breaking off at the opening 151a of the converter 151. The fastener 153 can have circumferentially closed internal threads. With this structure, after the converter 151 is fitted onto the base 120, the fastener 153 can apply a certain pushing force to the converter 151 through its engagement with the converter 151. Even if there is a slight error in the engagement of the first engagement body 121 and the second engagement body 1511 in the second direction, the fastener 153 can still achieve a slight displacement of the converter 151 through its engagement with the converter 151, ensuring the reliable fixation of the fastener 150 on the base 120, and thus ensuring the reliability of the venting connection assembly 100 in the toilet 30.

[0042] Continue to refer to Figure 2 In some embodiments, the fastener 153 includes an integrally formed threaded portion 1531 and a washer 1533. The washer 1533 is located at one end of the threaded portion 1531 and its outer diameter is larger than that of the threaded portion 1531. The thickness of the washer 1533 in the axial direction of the fastener 153 is less than the height of the threaded portion 1531 in the axial direction of the fastener 153. The internal thread can extend from the end of the threaded portion 1531 away from the washer 1533 to the washer 1533. During the process of the fastener 153 and the adapter 151 being screwed together to limit the venting connection assembly 100 in the toilet 30, the washer 1533 can press against the upper surface of the toilet mounting hole 30a on the toilet base. With the help of the reaction force of the toilet 30, the internal thread of the fastener 153 and the external thread of the adapter 151 are more tightly engaged, ensuring the reliability of the venting connection assembly 100 in the toilet 30.

[0043] Furthermore, in some embodiments, multiple reinforcing pieces 1535 can be evenly distributed around the threaded portion 1531. The reinforcing pieces 1535 are integrally formed with the threaded portion 1531 and the washer 1533. The reinforcing pieces 1535 can further enhance the strength of the connection structure between the threaded portion 1531 and the washer 1533, ensuring the connection reliability of the fastener 153.

[0044] Of course, in other embodiments, the threaded part 1531 and the washer 1533 can be two separate components that are installed together to provide a fastening connection.

[0045] refer to Figure 6 and Figure 7In other embodiments, the converter 151 may include two interlocking blocks 1513, which can be fitted into the base 120 along a first direction, such that the base 120 passes through the space formed by the two blocks 1513. The inner wall of the blocks 1513 may also be provided with a second engaging element 1511 to achieve engagement between the converter 151 and the base 120. The outer side of the converter 151 may be threaded and threadedly connected to the fastener 153 to limit the venting connection assembly 100 in the toilet 30. Of course, in other embodiments, the fastener 150 may have other structural forms, such as the converter 151 and the fastener 153 being integrally formed.

[0046] Further, refer to Figure 2 and combined Figure 1 , Figure 4 The ventilated connection assembly 100 may include a cap 160 covering the fastener 153, with the base 120 passing through the cap 160. The cap 160 is an approximately hollow frustum, with a through hole 160a at its upper end that matches the shape of the base 120. For example, the outer contours of both the through hole 160a and the cross-section of the base 120 are racetrack-shaped, while the lower end of the cap 160 is open. The entire cap 160 can be fitted over the base 120, allowing the base 120 to pass through the through hole 160a and the fastener 150 to be covered by the cap 160, thereby providing a certain degree of dust protection and protection for the fastener 150.

[0047] Continue to refer to Figure 1 and Figure 2 The ventilation connection assembly 100 may further include a connector 170, which is connected to the end of the base 120 away from the connection portion 110. The connector 170 is used to connect to the external pipe 700. The connector 170 can be connected to the external pipe 700. For example, the outer side of the connector 170 has threads for threaded connection with the external pipe 700, and the connector 170 has a through hole 170a. The connector 170 is sleeved on the base 120 through the through hole 170a and forms a tight fit with the base 120. For example, the connector 170 and the base 120 are interference-fitted or transition-fitted to ensure a reliable connection of the connector 170 to the base 120, thereby realizing a reliable connection between the external pipe 700 and the ventilation connection assembly 100.

[0048] Furthermore, the base 120 has an abutment portion 123 at the end away from the connecting portion 110, and the mating head 170 abuts against the abutment portion 123 to restrict the position of the mating head 170 on the base 120. Specifically, the width of the cross-section of the portion of the base 120 for which the mating head 170 is fitted is slightly smaller than the width of the portion of the base 120 not fitted with the mating head 170, thereby forming a stepped structure at the abutment portion 123. The width of the through hole 170a of the mating head 170 is smaller than the width of the portion of the base 120 not fitted with the mating head 170, thereby restricting the position of the mating head 170 on the base 120 by means of the abutment portion 123. Figure 4 As shown. It is understood that in some embodiments, the connector 170 can be connected to the base 120 in other ways, such as threaded connection, snap-fit ​​connection, etc. In other embodiments, the external pipe 700 can also be directly connected to the end of the base 120 away from the connecting portion 110 in other ways, such as snap-fit, snap-fit ​​connection, or reduced-length threaded connection. In other embodiments, the connector 170 and the abutment portion 123 can be omitted.

[0049] Continue to refer to Figure 1 and Figure 2 The connecting portion 110 has a third direction and includes an integrally formed main body 111 and reinforcing ribs 113. In the third direction, reinforcing ribs 113 are connected to the opposite side edges of the main body 111. In the second direction, the thickness of the reinforcing ribs 113 is less than the thickness of the main body 111. The main body 111 is used to pass through the first mounting groove 200a of the ventilator / drainage component 200, and the reinforcing ribs 113 are used to pass through the second mounting groove 200b of the ventilator / drainage component 200. The first direction, the second direction, and the third direction can be perpendicular to each other.

[0050] In the axial direction of the ventilator 200, at least a portion of the wall thickness of the ventilator 200 at the second mounting groove 200b is greater than the wall thickness at the first mounting groove 200a, and the shape of the first mounting groove 200a matches the shape of the body 111 of the ventilator connection assembly 100, and the shape of the second mounting groove 200b matches the shape of the reinforcing rib 113 of the ventilator connection assembly 100.

[0051] Specifically, the main body 111 and the reinforcing ribs 113 can be arranged in a mirror-symmetric manner with respect to the central plane of the base 120, where the central plane of the base 120 is a plane coplanar with the axis of the base 120 and perpendicular to the third direction. Further, in some embodiments, in the third direction, the main body 111 has a larger width than the base 120, the main body 111 used to define the first air passage 110a can have a relatively uniform wall thickness, and ribs 115 integrally formed with the main body 111 can be provided within the first air passage 110a. Figure 8This is to improve the structural stability of the connecting part 110 and prevent the connecting part 110 from deforming during assembly and use.

[0052] refer to Figure 8 In some embodiments, the reinforcing rib 113 extends in a long strip along a first direction and extends along a third direction in the width direction of the connecting portion 110. In other embodiments, the reinforcing rib 113 may extend in a straight line and form an angle with the third direction. Of course, in other embodiments, the reinforcing rib 113 may have more variations, such as being triangular, square, rectangular, or forked. Of course, in other embodiments, the reinforcing rib 113 may be omitted.

[0053] refer to Figure 9 and combined Figure 4 , Figure 5 A venting and draining component 200 is disposed between the toilet drain outlet 30c and the drain channel 40a, and its position is fixed relative to the toilet drain outlet 30c. It has a sewage channel 200c and an exhaust channel 200d. The sewage channel 200c connects to the toilet drain outlet 30c, and the exhaust channel 200d guides gas to be discharged into the drain channel 40a. The venting and draining component 200 has a side interface 200e and an exhaust port 200f. The exhaust port 200f can be located on the bottom or inner side of the venting and draining component 200 and connects to the drain channel 40a. The side interface 200e is used to insert the connecting part 110 of the venting connection assembly 100. The side interface 200e has the aforementioned first mounting groove 200a and second mounting groove 200b, with the second mounting groove 200b located at the edge of the width direction of the first mounting groove 200a. The exhaust vent 200f can be set in a complete circle around the sewage channel 200c and is spaced apart from the sewage channel 200c. The exhaust vent 200f is part of the exhaust channel 200d.

[0054] In accordance with the structure in which reinforcing ribs 113 are respectively protruding on opposite sides of the main body 111, the two sides of the width direction of the first mounting groove 200a each have a second mounting groove 200b. For example, after the ventilated connection assembly 100 is inserted into the ventilated drainage component 200, the axis of the base 120 can be substantially parallel to the axis of the ventilated drainage component 200, and the second mounting grooves 200b are distributed along a second direction on the opposite two edges of the first mounting groove 200a.

[0055] Since at least a portion of the wall thickness of the ventilator 200 at the second mounting groove 200b is greater than the wall thickness at the first mounting groove 200a in the axial direction of the ventilator 200, the first mounting groove 200a matches the shape of the main body 111 of the ventilator connection assembly 100, and the second mounting groove 200b matches the shape of the reinforcing rib 113 of the ventilator connection assembly 100, the cooperation between the second mounting groove 200b and the reinforcing rib 113 can better distribute the stress at the connection between the ventilator connection assembly 100 and the ventilator 200, thereby improving the structural strength of the connection.

[0056] In some embodiments, at least one of the base 120 and the connecting portion 110 is deformable and is used to extend from the bottom of the toilet 30 for connection. For example, see reference... Figure 10 The connecting portion 110 has a deformable section 117, the length of which is not limited. There is space between the bottom of the toilet 30 and the mounting floor for the connecting portion 110 to extend. The deformable section 117 of the deformable connecting portion 110 can be stretched, compressed, bent, or otherwise deformed so that the venting connection assembly 100 can extend from the bottom of the toilet 30. This eliminates the need for cutting or other operations on the toilet 30 itself, allowing for convenient modification of existing toilets 30, improving usability, and reducing the cost of modifying the toilet 30 for deodorization. In some embodiments, the deformable section 117 is corrugated.

[0057] In particular, in some implementations, such as Figure 3 The toilet mounting hole 30a shown may be in an uncertain or even missing position on the base of the toilet 30. For example, the position of the toilet mounting hole 30a relative to the drain channel 40a of some toilets 30 may vary. In such cases, the length of the deformable section 117 may be appropriately lengthened or shortened to fit the position of the toilet mounting hole 30a, thereby improving the ease of assembly.

[0058] The above-mentioned ventilation connection assembly 100 can be applied to the toilet deodorizing device 10. The ventilation connection assembly 100 includes a connecting part 110 and a base 120. The connecting part 110 extends along a first direction and has a first air passage 110a. The connecting part 110 is used to connect with the ventilation and drainage component 200 so that the first air passage 110a is finally connected to the sewage passage 40a of the toilet 30. The base 120 extends along a second direction and has a second air passage 120a. The second direction is set at an angle to the first direction, and the second air passage 120a is connected to the first air passage 110a. The outer contour of the cross-section of the base 120 is non-circular. The base 120 is used to pass through the toilet mounting hole 30a of the toilet 30. The second air passage 120a is used to connect to the fan assembly 500 of the toilet deodorizing device 10. The first air duct 110a of the ventilation connection assembly 100 is ultimately connected to the sewage discharge channel 40a of the toilet 30. The fan assembly 500 of the toilet deodorizing device 10 guides the odorous gas inside the toilet bowl 31 to be discharged into the sewage discharge channel 40a. This design is more widely applicable to various toilet 30 installation environments, avoiding the hassle of opening holes in external walls, drilling holes or raising floors, installing exhaust fans, and installing additional pipes. When the toilet mounting hole 30a is non-circular, such as racetrack-shaped, the outer contour of the cross-section of the base 120 can be set to a racetrack shape, ellipse, or rectangle, etc., to maximize the cross-sectional size of the first air duct 110a, thereby reducing wind resistance and improving the deodorization efficiency of the toilet deodorizing device 10. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
