Description

Technical Field

[0001] The utility model relates to a three-proof valve used in air-conditioning pipelines. Background Art

[0002] With the improvement of living standards, almost every household now has an air conditioner. However, various problems often arise during the use of air conditioners. Among the more common problems are: 1. When the wall downspout is clogged, dirty water may flow back into the air conditioner's indoor unit; 2. Small insects such as cockroaches may enter the indoor unit through the condenser pipe and reproduce indoors; 3. In some cases, the condenser pipe of the installed air conditioner is directly connected to the sewer pipe. Therefore, there is a certain possibility that odors in the sewer pipe will flow through the sewer pipe and spread into the room through the indoor unit. When the air conditioner is in use, if these problems occur, it will cause urgent inconvenience to people's lives. Summary of the Invention

[0003] In view of the above-mentioned deficiencies, the utility model provides an air conditioner three-proof valve which can improve the reliability of air conditioning use, effectively prevent odor from entering the hole through the condensation water pipe, prevent dirty water from flowing back into the air conditioner due to blockage of the water pipe outside the wall, and effectively prevent small insects from entering the room along the condensation water pipe.

[0004] To achieve the above objectives, the utility model adopts an air conditioner three-proof valve, including a valve body and a blocking member placed in the valve body. The valve body includes a water outlet end distributed on one end of the valve body for connecting to the condensation water pipe on the air conditioner indoor unit, and an external connection end distributed on the other end of the valve body and facing the outside. A movement limit portion of the blocking member is formed in the valve body relative to the water outlet end and the external connection end, and an inner extension portion is also formed on the side of the valve body facing the external connection end;

[0005] The blocking member includes a limiting portion and an elastic portion, wherein one end of the limiting portion is limited in the valve body, and the other end of the limiting portion is freely extended toward the end away from the limiting portion in the valve body, one end of the elastic portion is connected to the limiting portion, and the other end of the elastic portion extends obliquely in the same direction as the other end of the limiting portion, and is mounted on the inner extension portion;

[0006] By means of the limiting part and the limiting part in the valve body, and the installation of the other end of the elastic part on the inner extension part, a connection block is formed between the external end of the valve body and the water outlet end, and by means of the installation of the other end of the elastic part on the inner extension part, a one-way opening setting is formed between the water outlet end and the external end.

[0007] The beneficial effect of the above structure is that: by involving a blocking member in the valve body to be used, a water outlet end that can be connected to the air conditioner indoor unit and an external connection end extending to the outside are also opened on both ends of the valve body, wherein the blocking member mainly includes a limiting part and an elastic part. At the same time, one end of the limiting part is designed to be able to be positioned on the upper limit of the valve body, and the other end extends into the inner valve body, and the elastic part is connected to the limiting part at one end, and the other end of the elastic part and the other end of the limiting part are structured to be able to extend in the same direction. In addition, there is a corresponding blocking member moving limiting part in the valve body, and an internal extension part is formed relative to the side facing the external connection end, that is, after one end of the limiting part is limited in the valve body, the elastic part connected to the limiting part follows the direction of the other end of the limiting part. It extends obliquely, and after the oblique extension, it is mounted on the inner extension part, thereby forming a blocking space for the valve body relative to the position toward the external end, and since the elastic part is designed to be mounted on the inner extension part, that is, due to the obstruction of the mounting, the elastic part cannot continue to move toward the direction of the inner extension part, so that when the valve body is in use, the three-proof valve can only be opened in the direction from the water outlet end toward the external end, and cannot be opened in the opposite direction. As a result, when the three-proof valve is used on the condensing water pipe on the indoor unit of the air conditioner, it can prevent odors, small insects, backflow water, or external noise from entering the indoor unit of the air conditioner through the condensing water pipe, and also ensure comfortable and worry-free use of the air conditioner, and also ensure that the air blown out of the indoor unit is fresh.

[0008] The utility model is further configured such that the movement limit portion of the blocking member is an insertion groove opened on the valve body and adapted to the side of the blocking member, and the movement limit of the blocking member in the valve body is formed by inserting the two side edges of the blocking member into the insertion groove.

[0009] Through the above, the blocking member can be reliably limited in the valve body, thereby avoiding the situation where the protection of the three-proof valve is unreliable due to unreliable design.

[0010] The utility model is further configured such that the valve body includes a valve shell and a valve cover that is detachably connected to the valve shell. The water outlet end and the external connection end are both distributed on the valve shell. The insertion groove is distributed between the water outlet end and the external connection end formed on the valve shell. The valve cover is provided with a valve cover insertion groove that is adapted to the top side of the blocking member. Through the cooperation between the valve cover insertion groove and the top side of the blocking member, a blocking partition on the valve cover side is formed.

[0011] By designing the valve body in the manner involving the valve shell and the valve cover as described above, the blocking member involved in the three-proof valve can be conveniently placed in the valve body, thereby further ensuring the reliability of the design. The use of a detachable split structure involving the valve shell and the valve cover can also allow the three-proof valve to be opened through the valve cover after being used for a period of time, and then the blocking member can be cleaned, thereby avoiding excessive dirt in the three-proof valve due to long-term use, which affects the reliability of use and greatly extends the service life.

[0012] The utility model is further configured such that the valve housing also includes a partition plate distributed on one side of the water outlet end and a blocking member limit block distributed on one side of the external end, which is formed between the partition plate and the blocking member limit block for the elastic part to extend obliquely and be erected. The partition plate extends from the valve cover area to the bottom of the valve housing, and the blocking member limit block is an inclined structure, and extends toward the inner extension part relative to the side away from the through groove and is connected to the inner extension part. The insertion groove is a clamping groove formed between the partition plate and the blocking member limit block for the limiting part on the blocking member to be clamped.

[0013] Through the above, the reliable limitation of the blocking member to the valve housing can be further ensured.

[0014] The utility model is further configured such that an elastic sealing ring is sleeved and limited on the outer edge of the valve housing on the side connected to the valve cover, and a tight-fitting connection is formed between the valve housing and the valve cover through the elastic sealing ring.

[0015] The above-mentioned design of the elastic sealing ring can ensure a reliable connection between the valve housing and the valve cover, as well as convenient disassembly and assembly. At the same time, when small insects, dirty water backflow, etc. occur, it is not easy to be accidentally opened, thereby affecting the reliability of use.

[0016] The present invention is further configured such that the valve cover is formed with a mark for marking the direction of water flow.

[0017] The marking of the water flow direction can be used to let the installer know which end of the three-proof valve is connected to the condensate pipe and which end faces the outside world, thereby further ensuring the reliability of the use of the three-proof valve of the utility model and greatly reducing the occurrence of the three-proof valve being reversed.

The valve body 1 includes a water outlet a located at one end of the valve body 1 for connection to a condensate pipe on an indoor unit of the air conditioner, and an external connection b located at the other end of the valve body 1 and facing the outside. A blocking member movement limiter 21 is formed within the valve body 1 between the water outlet a and the external connection b, and an inner extension 124 is further formed within the valve housing 12 on a side facing the external connection b.

[0025] The blocking member 2 includes a limiting portion 21 and an elastic portion 22. One end of the limiting portion 21 is limited within the valve body 1, and the other end of the limiting portion 21 is freely extended toward the end away from the limit within the valve body 1. One end of the elastic portion 22 is connected to the limiting portion 21, and the other end of the elastic portion 22 extends obliquely in the same direction as the other end of the limiting portion 21 and is mounted on the inner extension portion 124.

[0026] By limiting the position of the limiting portion 21 and the valve body 1, and by mounting the other end of the elastic portion 22 on the inner extension portion 124, the connection between the external end b and the water outlet end a of the valve body 1 is blocked, and by mounting the other end of the elastic portion 22 on the inner extension portion 124, a one-way opening setting is formed between the water outlet end a and the external end b.

[0027] The above-mentioned valve body 1 involves a blocking member 2, and at both ends of the valve body 1, a water outlet a that can be connected to the air conditioner indoor unit and an external connection end b extending to the outside are provided, wherein the blocking member 2 mainly includes a limiting portion 21 and an elastic portion 22. At the same time, one end of the limiting portion 21 is designed to be able to be positioned in the upper limit of the valve body 1, and the other end extends into the valve body 1, while the elastic portion 22 is connected to the limiting portion 21 at one end, and the other end of the elastic portion 22 and the other end of the limiting portion 21 are structured to be extendable in the same direction. In addition, the valve body 1 correspondingly involves a blocking member moving limiting portion 21, and an inner extension portion 124 is formed relative to the side facing the external connection end b, that is, after one end of the limiting portion 21 is limited in the valve body 1, the elastic portion 22 is connected to the limiting portion 21 and moves with the limiting portion 21. The valve body 1 is obliquely extended in the direction of the other end, and after the oblique extension, it is mounted on the inner extension part 124, thereby forming a blocking space relative to the position of the valve body 1 toward the external end b, and since the elastic part 22 adopts a structural design mounted on the inner extension part 124, that is, due to the obstruction of the mounting, the elastic part cannot continue to move in the direction of the inner extension part 124, so that when the valve body 1 is used, the three-proof valve can only be opened in the direction from the water outlet end a toward the external end b, and cannot be opened in the opposite direction, and thus when the three-proof valve is used on the condensing water pipe on the indoor unit of the air conditioner, it can prevent odors, small insects, backflow water, or external noise from entering the indoor unit of the air conditioner through the condensing water pipe, and also ensure the comfort and worry-free use of the air conditioner, and also ensure that the air blown out of the indoor unit is fresh.

[0028] like Figure 2-3 As shown in Figures 6 and 7, the blocking member movement limit portion 21 is an insertion groove 123 opened on the valve body 1 and adapted to the side of the blocking member 2. By inserting the two side edges of the blocking member 2 into the insertion groove 123, the movement limit of the blocking member 2 in the valve body 1 is formed.

[0029] like Figure 1-3 As shown in Figures 6 and 7, the valve body 1 includes a valve shell 12 and a valve cover 11 which is detachably connected to the valve shell 12. The water outlet end a and the external end b are both distributed on the valve shell 12. The insertion groove 123 is distributed between the water outlet end a and the external end b formed on the valve shell 12. The valve cover 11 is provided with a valve cover insertion groove 111 which is adapted to the top side of the blocking member 2. The valve cover insertion groove 111 cooperates with the top side of the blocking member 2 to form a blocking partition on the side of the valve cover 11. An elastic sealing ring is sleeved and limited on the outer edge of the valve shell 12 on the side connected to the valve cover 11. The elastic sealing ring forms a tight connection between the valve shell 12 and the valve cover 11.

[0030] like Figure 2 、 6As shown, the above-mentioned valve housing 12 also includes a partition plate 122 distributed on the side of the water outlet end a and a blocking member limit block 121 distributed on the side of the external end b, which is formed between the partition plate 122 and the blocking member limit block 121 for the elastic part 22 to extend obliquely and be erected. The partition plate 122 extends from the valve cover 11 area to the bottom of the valve housing 12. The blocking member limit block 121 has an inclined structure, and extends toward the direction of the inner extension part 124 relative to the side away from the through groove, and is connected to the inner extension part 124. The insertion groove 123 is a clamping groove formed between the partition plate 122 and the blocking member limit block 121 for the limiting part 21 on the blocking member 2 to be clamped.
