[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] Example 1:

[0043] As shown in Figures 1-13, this utility model provides an odor isolation valve for use in air conditioners to isolate odors during condensate drainage. Of course, this odor isolation valve can also be applied to other electrical appliances with drainage or waste disposal needs, and is not limited to air conditioners. Specifically, the odor isolation valve includes a valve body 1 with an inlet end 3 at the top and an outlet end 2 at the bottom. Further, the top of the valve body 1 is the inlet end 3, through which condensate enters, and the bottom of the valve body 1 is the outlet end 2. The inlet end 3 and the outlet end 2 are connected by a water passage cavity 4 formed in the valve body 1. Condensate enters the valve body 1 through the inlet end 3, then flows out from the outlet end 2 after passing through the water passage cavity 4. The water passage cavity 4 is equipped with a double isolation structure to achieve odor isolation between the inlet end 3 and the outlet end 2.

[0044] Furthermore, the two isolation structures are arranged in sequence to form a double isolation effect. The odor isolation valve provided by this utility model achieves double isolation by setting a double isolation structure between the water inlet and the water outlet to prevent the backflow of air conditioning odors.

[0045] As an optional embodiment of this utility model, the double isolation structure includes a perforated tortuous flow channel formed in the water passage cavity 4 and a float-type unidirectional conduction component 8.

[0046] This utility model features a dual-isolation structure. The first layer is a perforated tortuous flow channel, which acts as a water trap to effectively prevent the backflow of odors in the drainage system. The second layer is a float-type one-way flow assembly. As the amount of discharged condensate increases, the float gradually rises under the action of buoyancy until it overcomes its own weight, opening the valve and allowing the condensate to flow out smoothly. This process not only achieves a second layer of isolation but also further enhances the function of isolating odors. It also features a simple structure, low cost, easy installation, and low-cost odor isolation. Furthermore, the float-type one-way flow assembly of this utility model solves the problem of one-way seal failure during long-term operation.

[0047] Specifically, the first-stage perforated tortuous flow channel consists of the following structure: a water-blocking and guiding structure 5 is formed inside the valve housing 1 to block and guide the water flow in the water passage cavity 4; further, in this embodiment, the water-blocking and guiding structure 5 is a hollow cylindrical structure formed in the water passage cavity 4, one end of the water-blocking and guiding structure 5 is open, and the other end is connected to a support platform formed vertically on the inner wall of the valve housing 1; a connecting cover 6 is provided on the outer side of the water-blocking and guiding structure 5, the top of the connecting cover 6 is an arc-shaped closed structure, and the bottom of the connecting cover 6 is detachably connected to the support platform; through the above structural settings, the condensate entering through the water inlet 3 is guided to the surrounding area under the action of the arc-shaped structure at the top of the connecting cover 6, and then flows in the channel formed between the inner wall of the valve housing 1 and the outer wall of the connecting cover 6; a plurality of water passage holes 61 are opened on the connecting cover 6; the inner wall of the valve housing 1, the water passage holes 61, and the water-blocking and guiding structure 5 form a perforated tortuous flow channel.

[0048] When condensate flows, it first enters through the inlet 3, then enters the water passage 4, and then flows into the beginning section of the tortuous flow channel formed by the inner wall of the valve body 1 and the connecting cover 6. Then it flows through the water hole 61 into the middle section of the tortuous flow channel formed by the connecting cover 6 and the water-blocking and guiding structure 5. Then it flows through the middle section of the tortuous flow channel to the top of the connecting cover 6, and finally flows out from the inner cavity of the water-blocking and guiding structure 5, which is the rear section of the tortuous flow channel. Finally, it flows out sequentially from the double float-type unidirectional guide assembly, the lower part of the water passage 4, and the outlet 2.

[0049] Specifically, the float-type one-way flow assembly 8 consists of the following structure: a funnel-shaped confluence pool 81 is formed inside the valve housing 1 at the bottom of the water-blocking and flow-guiding structure 5; a flow port 82 is opened at the bottom of the confluence pool 81; a float 83 is placed on the flow port 82; the float 83 and the flow port 82 are connected by a spherical seal; the confluence pool 81, the flow port 82 and the float 83 form the float-type one-way flow assembly 8.

[0050] Specifically, the top of the manifold 81 is connected to the support platform, so that when the float 83 and the guide port 82 are spherically sealed, the water passage cavity 4 will not be completely open and will be isolated. The guide port 82 will only be open when the float 83 floats. Therefore, when there is no condensate discharge, the float 83 will completely seal the guide port 82 to prevent odor backflow. Moreover, the design of the manifold 81 and the float 83 can also prevent bacteria from growing in the area near the lower drainage channel, thereby preventing odor backflow. The float-type one-way guide component 8 can also prevent the problem of one-way seal failure during long-term operation.

[0051] In this utility model, the air conditioner odor isolation valve has an inlet end 3 consisting of a valve shell 1 and a connecting cover 6 with a water passage hole 61 on the wall, forming a tortuous flow channel to achieve the first layer of isolation; the outlet end 2 consists of a funnel-shaped confluence pool 81, a guide port 82 and a plastic float 83, which utilize the buoyancy of water to achieve unidirectional flow channel and achieve double isolation.

[0052] As a further improvement of this utility model, the float 83 is made of plastic.

[0053] To prevent the float 83 from losing its position when it floats, in this embodiment, a protective net 7 is provided inside the water-blocking and guiding structure 5 to limit the floating height of the float 83.

[0054] By setting up a protective net 7, this utility model can not only prevent the plastic ball from falling out of place, but also ensure the flow of condensate. Furthermore, the protective net 7 is installed less than 10mm from the top, where the top refers to the top of the water-blocking and guiding structure 5.

[0055] In order to improve the efficiency of condensate flow and ensure smooth flow in different directions, in this embodiment, the water passage hole 61 is arranged around the circumference of the connecting cover 6.

[0056] Furthermore, the water passage 61 is divided into multiple layers to maximize the efficiency of condensate flow.

[0057] In this embodiment, six sets of water passage holes 61 are provided. Each set of water passage holes 61 is arranged in multiple layers.

[0058] To prevent the flow from becoming erratic and failing, in this embodiment, the highest water passage 61 is located below the top edge of the water-blocking and guiding structure 5.

[0059] In this embodiment, the top diameter of the manifold 81 is equal to the diameter of the water-blocking and guiding structure 5. This structural design reduces the resistance to condensate flow and ensures smooth flow.

[0060] As shown in Figures 11 and 12, for ease of maintenance, in this embodiment, the valve housing 1 is a split structure, including an upper valve housing 11 and a lower valve housing 12 that are interlocked together. The upper valve housing 11 and the lower valve housing 12 are detachably connected by a screwing structure.

[0061] Specifically, as shown in Figures 2 and 12, the upper valve housing 11 has four tightening buckles 111 arranged around its bottom circumference, and the lower valve housing 12 has four tightening hooks 121 arranged around its top circumference. Each tightening buckle 111 has an inlet and a clamping platform at its bottom. During installation, the tightening hooks 121 extend into the inlet at the bottom of the tightening buckle 111, and then the upper valve housing 11 and the lower valve housing 12 rotate relative to each other, causing one side of the tightening hook 121 to engage with the clamping platform, thus achieving a rotational clamping connection between the upper valve housing 11 and the lower valve housing 12. It should be noted that the clamping platforms are located on both sides of the inlet, allowing the upper valve housing 11 and the lower valve housing 12 to be clamped regardless of rotation in either direction.

[0062] As a further improvement of this utility model, as shown in Figure 13, the connecting cover 6 and the valve housing 1 are detachably connected.

[0063] Specifically, the bottom of the connecting cover 6 is provided with a tightening protrusion structure, and the valve body 1 is provided with a tightening groove 122 that is adapted to the tightening protrusion structure at the corresponding position; the tightening protrusion structure and the tightening groove are tightened and connected.

[0064] The connecting cover of this utility model has multiple sets of water passage holes evenly distributed on it to ensure smooth drainage. The bottom is provided with four sets of raised structures. These raised structures not only enhance the rigidity of the connecting cover, but also cooperate with the groove of the lower top cover and are fixed by screwing. This design not only simplifies the installation and maintenance process, but also greatly improves the reliability and durability of the product.

[0065] Example 2:

[0066] The present invention provides a pipeline assembly, including the odor isolation valve in Embodiment 1.

[0067] Example 3:

[0068] The present invention provides an air conditioner, including the above-mentioned piping assembly.

[0069] The piping assembly includes an odor isolation valve, which comprises a valve body 1 with an inlet end 3 at the top and an outlet end 2 at the bottom. Furthermore, the top of the valve body 1 is the inlet end 3, through which condensate enters, and the bottom of the valve body 1 is the outlet end 2. The inlet end 3 and the outlet end 2 are connected by a water passage cavity 4 formed in the valve body 1. Condensate enters the valve body 1 through the inlet end 3, then flows out through the water passage cavity 4 and exits from the outlet end 2. The water passage cavity 4 is equipped with a double isolation structure to achieve odor isolation between the inlet end 3 and the outlet end 2.

[0070] Furthermore, the two isolation structures are arranged in sequence to form a double isolation effect. The air conditioner odor isolation valve provided by this utility model achieves double isolation by setting a double isolation structure between the water inlet and the water outlet to prevent the backflow of air conditioner odors.

[0071] As an optional embodiment of this utility model, the double isolation structure includes a perforated tortuous flow channel formed in the water passage cavity 4 and a float-type unidirectional conduction component 8.

[0072] This utility model features a dual-isolation structure. The first layer is a perforated tortuous flow channel, which acts as a water trap to effectively prevent the backflow of odors in the drainage system. The second layer is a float-type one-way flow assembly. As the amount of discharged condensate increases, the float gradually rises under the action of buoyancy until it overcomes its own weight, opening the valve and allowing the condensate to flow out smoothly. This process not only achieves a second layer of isolation but also further enhances the function of isolating odors. It also features a simple structure, low cost, easy installation, and low-cost odor isolation. Furthermore, the float-type one-way flow assembly of this utility model solves the problem of one-way seal failure during long-term operation.

[0073] Specifically, the first-stage perforated tortuous flow channel consists of the following structure: a water-blocking and guiding structure 5 is formed inside the valve housing 1 to block and guide the water flow in the water passage cavity 4; further, in this embodiment, the water-blocking and guiding structure 5 is a hollow cylindrical structure formed in the water passage cavity 4, one end of the water-blocking and guiding structure 5 is open, and the other end is connected to a support platform formed vertically on the inner wall of the valve housing 1; a connecting cover 6 is provided on the outer side of the water-blocking and guiding structure 5, the top of the connecting cover 6 is an arc-shaped closed structure, and the bottom of the connecting cover 6 is detachably connected to the support platform; through the above structural settings, the condensate entering through the water inlet 3 is guided to the surrounding area under the action of the arc-shaped structure at the top of the connecting cover 6, and then flows in the channel formed between the inner wall of the valve housing 1 and the outer wall of the connecting cover 6; a plurality of water passage holes 61 are opened on the connecting cover 6; the inner wall of the valve housing 1, the water passage holes 61, and the water-blocking and guiding structure 5 form a perforated tortuous flow channel.

[0074] When condensate flows, it first enters through the inlet 3, then enters the water passage 4, and then flows into the beginning section of the tortuous flow channel formed by the inner wall of the valve body 1 and the connecting cover 6. Then it flows through the water hole 61 into the middle section of the tortuous flow channel formed by the connecting cover 6 and the water-blocking and guiding structure 5. Then it flows through the middle section of the tortuous flow channel to the top of the connecting cover 6, and finally flows out from the inner cavity of the water-blocking and guiding structure 5, which is the rear section of the tortuous flow channel. Finally, it flows out sequentially from the double float-type unidirectional guide assembly, the lower part of the water passage 4, and the outlet 2.

[0075] Specifically, the float-type one-way flow assembly 8 consists of the following structure: a funnel-shaped confluence pool 81 is formed inside the valve housing 1 at the bottom of the water-blocking and flow-guiding structure 5; a flow port 82 is opened at the bottom of the confluence pool 81; a float 83 is placed on the flow port 82; the float 83 and the flow port 82 are connected by a spherical seal; the confluence pool 81, the flow port 82 and the float 83 form the float-type one-way flow assembly 8.

[0076] Specifically, the top of the manifold 81 is connected to the support platform, so that when the float 83 and the guide port 82 are spherically sealed, the water passage cavity 4 will not be completely open and will be isolated. The guide port 82 will only be open when the float 83 floats. Therefore, when there is no condensate discharge, the float 83 will completely seal the guide port 82 to prevent odor backflow. Moreover, the design of the manifold 81 and the float 83 can also prevent bacteria from growing in the area near the lower drainage channel, thereby preventing odor backflow. The float-type one-way guide component 8 can also prevent the problem of one-way seal failure during long-term operation.

[0077] In this utility model, the air conditioner odor isolation valve has an inlet end 3 consisting of a valve shell 1 and a connecting cover 6 with a water passage hole 61 on the wall, forming a tortuous flow channel to achieve the first layer of isolation; the outlet end 2 consists of a funnel-shaped confluence pool 81, a guide port 82 and a plastic float 83, which utilize the buoyancy of water to achieve unidirectional flow channel and achieve double isolation.

[0078] As a further improvement of this utility model, the float 83 is made of plastic.

[0079] To prevent the float 83 from losing its position when it floats, in this embodiment, a protective net 7 is provided inside the water-blocking and guiding structure 5 to limit the floating height of the float 83.

[0080] By setting up a protective net 7, this utility model can not only prevent the plastic ball from falling out of place, but also ensure the flow of condensate. Furthermore, the protective net 7 is installed less than 10mm from the top, where the top refers to the top of the water-blocking and guiding structure 5.

[0081] In order to improve the efficiency of condensate flow and ensure smooth flow in different directions, in this embodiment, the water passage hole 61 is arranged around the circumference of the connecting cover 6.

[0082] Furthermore, the water passage 61 is divided into multiple layers to maximize the efficiency of condensate flow.

[0083] In this embodiment, six sets of water passage holes 61 are provided. Each set of water passage holes 61 is arranged in multiple layers to ensure smooth drainage.

[0084] To prevent the flow from becoming erratic and failing, in this embodiment, the highest water passage 61 is located below the top edge of the water-blocking and guiding structure 5.

[0085] In this embodiment, the top diameter of the manifold 81 is equal to the diameter of the water-blocking and guiding structure 5. This structural design reduces the resistance to condensate flow and ensures smooth flow.

[0086] As shown in Figures 11 and 12, for ease of maintenance, in this embodiment, the valve housing 1 is a split structure, including an upper valve housing 11 and a lower valve housing 12 that are interlocked together. The upper valve housing 11 and the lower valve housing 12 are detachably connected by a screwing structure.

[0087] Specifically, as shown in Figures 2 and 12, the upper valve housing 11 has four tightening buckles 111 arranged around its bottom circumference, and the lower valve housing 12 has four tightening hooks 121 arranged around its top circumference. Each tightening buckle 111 has an inlet and a clamping platform at its bottom. During installation, the tightening hooks 121 extend into the inlet at the bottom of the tightening buckle 111, and then the upper valve housing 11 and the lower valve housing 12 rotate relative to each other, causing one side of the tightening hook 121 to engage with the clamping platform, thus achieving a rotational clamping connection between the upper valve housing 11 and the lower valve housing 12. It should be noted that the clamping platforms are located on both sides of the inlet, allowing the upper valve housing 11 and the lower valve housing 12 to be clamped regardless of rotation in either direction.

[0088] As a further improvement of this utility model, as shown in Figure 13, the connecting cover 6 and the valve housing 1 are detachably connected.

[0089] Specifically, the bottom of the connecting cover 6 is provided with a screw-on protrusion structure. These protrusions not only enhance the rigidity of the connecting cover, but also fix it by screwing it in place through a groove in the lower valve housing 12. A screw-on groove 122 adapted to the screw-on protrusion structure is provided at a corresponding position on the valve housing 1. The screw-on protrusion structure and the screw-on groove are screwed together.

[0090] The locking structure in this invention not only simplifies the installation and maintenance process, but also greatly improves the reliability and durability of the product.

[0091] The connecting cover of this utility model has multiple sets of water passage holes evenly distributed on it to ensure smooth drainage. The bottom is provided with four sets of raised structures. These raised structures not only enhance the rigidity of the connecting cover, but also cooperate with the groove of the lower top cover and are fixed by screwing. This design not only simplifies the installation and maintenance process, but also greatly improves the reliability and durability of the product.

[0092] When the air conditioner is not draining, the inlet and outlet pipes are vertically connected, as shown in Figure 4. Under the action of gravity, the plastic float 83 is sealed to the spherical surface of the guide port 82 to achieve a first layer of isolation.

[0093] As shown in Figure 5, when the air conditioner starts draining water, the condensate will sequentially pass through multiple sets of water passages 61 on the upper valve housing 11 and the connecting cover 6, entering the funnel-shaped confluence pool 81 structure of the lower valve housing 12. The connecting cover 6 and the water-blocking and guiding structure 5 together form a tortuous flow channel, which acts as a water trap, effectively preventing the backflow of odors in the drainage system. As shown in Figure 5, as the amount of condensate discharged increases, the plastic float 83 gradually rises under the action of buoyancy until it overcomes its own weight, the guide port 82 opens, and the condensate flows out smoothly. This process not only achieves double isolation but also further enhances the function of isolating odors.

[0094] The air conditioner provided by this utility model is equipped with an odor isolation valve with a double isolation structure. The tortuous flow channel combined with the unidirectional conduction structure achieves a double isolation barrier.
