[0002] Flue check valves are generally installed on the exhaust pipes of kitchens and bathrooms. Flue check valves can not only prevent the backflow of oil smoke and moisture, but also effectively prevent other harmful gases and oil smoke in the public flue from flowing back into your home, ensuring family air hygiene. The four corners of the existing flue check valve are generally provided with installation holes. The flue check valve is fixedly installed on the flue opening by punching holes in the wall of the flue opening. The installation process requires the control of the installation dimensions. If you are not careful, you need to punch holes again; if you want to replace the flue check valve, you need to punch holes in the wall again. It can be seen that the installation process of the existing flue check valve is not only cumbersome and inflexible, but also requires professional wall punching tools, which is time-consuming and labor-intensive, and has high installation costs. Therefore, it is necessary to solve the installation problem of the above-mentioned flue check valve.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Please check Figures 1 to 4 The preferred embodiment of the utility model provides a mounting base and a flue check valve having the mounting base, wherein the mounting base can be installed on flue openings in kitchens, bathrooms, etc. where smoke needs to be extracted and indoor gas needs to be replaced, and the flue check valve can be fixed on the mounting base, so that the flue check valve blocks the backflow or backflow of oil smoke or harmful gases from the flue opening.

[0033] Specifically, the above-mentioned mounting base includes a crossbar 10 and a base body 20. To ensure the structural firmness and stability of the mounting base, it is preferred that the crossbar 10 and the base body 20 are both made of hard metal materials, such as stainless steel, copper, or aluminum alloy. Further, the crossbar 10 and the base body 20 can be fixedly connected by a long rod bolt 30, wherein the crossbar 10 and the base body 20 are relatively arranged on the inner and outer sides of the flue opening, that is, the crossbar 10 is on the inner side of the flue opening, and the base body 20 is on the outer side of the flue opening, so that the crossbar 10 and the base body 20 clamp the flue opening between the two, then, the bolt 30 is inserted into the threaded holes 40 on the base body 20 and the crossbar 10 in sequence, and then the bolt 30 is screwed. As the bolt 30 is tightened, the distance between the crossbar 10 and the base body 20 is gradually shortened, so the crossbar 10 and the base body 20 are respectively fixed on the wall around the flue opening, that is, the installation of the mounting base on the flue opening is completed. In addition, in order to ensure the horizontality of the mounting base during installation, a level ruler 23 is preferably provided on the base body 20, so that people can refer to the level ruler 23 to meet the installation requirements of the mounting base. In this way, the installation process does not require drilling holes in the wall or using special equipment, and the mounting base is fixed on the flue port. The operation process is simple, efficient, and time-saving and labor-saving.

[0034] Please continue viewing Figure 1 to Figure 2 The cross bar 10 is a strip-shaped U-shaped groove, wherein the open end of the U-shaped groove is in an arc shape with a gradually higher middle and gradually lower sides, that is, more material is used in the middle and less material is used on the sides. Such a design is due to the threaded hole 40 in the middle of the cross bar 10. Therefore, when the cross bar 10 is subjected to the torsion of the bolt 30, the support stability of the cross bar 10 can be guaranteed, and materials can be saved to reduce manufacturing costs. Furthermore, the bottom of the U-shaped groove on the cross bar 10 is a plane. In particular, the length of the cross bar 10 is greater than the diameter of the flue port. In this way, the cross bar 10 can be made to have a sufficient length so that its plane bottom can be firmly against the wall where the flue port is located, providing a support foundation for the fixation of the mounting base.

[0035] Further, the cross section of the base body 20 is preferably rectangular, and a through hole 21 is passed through the center thereof, and the through hole 21 can be connected to the flue port. In particular, in order to make the through hole 21 match any flue port, the diameter of the through hole 21 is preferably greater than or equal to the diameter of the flue port. Specifically, the through hole 21 protrudes and extends along its outer circumference to the same side to form an outer frame 22. The outer frame 22 formed in this way has a certain thickness, preferably 20%-35% of the diameter of the through hole. The outer frame 22 can be covered on the flue port, and then a certain space distance is left between the through hole 21 and the flue port. In addition, the periphery of the outer frame 22 is turned outward to form an outer flange 221 that is perpendicular to the outer frame 22. The outer flange 221 can directly abut against the wall around the flue port, so that the base body 20 can be firmly abutted against the flue port. In addition, a sealing gasket (not shown) is provided on the outer flange 221 to maintain sealing between the base body 20 and the wall around the flue opening. In this way, the gas in the public flue can be prevented from flowing back into the room through the gap between the base body and the wall, ensuring the cleanliness and hygiene of the indoor air.

[0036] Furthermore, a support rod 211 is fixedly provided on the base body 20. The support rod 211 is perpendicular to the bolt 30 and passes through the center of the through hole 21. The support rod 211 is erected in the center of the through hole 21, dividing the through hole 21 into two, so that the through hole 21 is divided into two semicircular airflow holes (not shown). Specifically, a threaded hole 40 is provided in the middle of the support rod 211, and correspondingly, a threaded hole 40 is also provided in the middle of the cross bar 10. In this way, the bolt 30 passes through the two threaded holes 40 to fix the mounting base on the flue port.

[0037] Please check Figure 3 to Figure 4 In the prior art, the flue check valve includes a base 50, a valve housing 60, and two semicircular valve covers 70 movably arranged on the valve housing 60. The specific structure and function thereof belong to the known technology and are not described here in detail.

[0038] Furthermore, the mounting base of the preferred embodiment of the present utility model can be fixedly mounted and connected with the flue check valve. Specifically, the four corners of the flue check valve are provided with mounting holes, namely the second mounting holes 51, and the second mounting holes 51 are preferably transverse holes, so as to provide the screws with more flexible and adjustable mounting space. The four corners of the above-mentioned base body 20 are also provided with mounting holes, namely the first mounting holes 24, so that the first mounting holes 24 and the second mounting holes 51 can be fixedly connected by screws and nuts, so that the flue check valve is fixedly mounted on the mounting base. Since the position of the mounting base relative to the flue opening has been adjusted and optimized when the mounting base is fixed at the flue opening, when the flue check valve is installed on the mounting base, there is no need to adjust the position of the flue check valve relative to the flue opening, and the flue check valve only needs to be directly fixed on the mounting base to complete the installation of the flue check valve relative to the flue opening. It can be seen that by installing the flue check valve relative to the flue opening through the installation base, there is no need to drill holes in the wall, that is, there is no need to destroy the original appearance of the wall, and there is no need to use special equipment, so the installation of the flue check valve on the flue opening can be completed quickly, conveniently and accurately. Moreover, because a sealing gasket is provided on the base body 20, the backflow of gas in the public flue into the home is also avoided, which saves time and effort, and has a significant smoke isolation effect. In addition, the installation base of the preferred embodiment of the utility model has no special requirements for the flue check valve, and only needs to have an installation hole. Therefore, the installation base of the utility model has strong adaptability to the flue check valve and a wide range of applications. It can facilitate people's subsequent replacement and maintenance of the flue check valve. In particular, when a new flue check valve needs to be replaced, it only needs to loosen the screws, install the new one and discard the old one, without the need for cumbersome disassembly and installation process. The operation is flexible and convenient, saving time and effort.

[0039] Furthermore, the two semicircular valve covers 70 on the flue check valve are in an active open state during the extraction process in the kitchen and bathroom. When the flue check valve is installed on the mounting base, the two semicircular valve covers 70 are in the through hole 21, that is, each valve cover 70 can be placed in a semicircular airflow hole (not shown) one by one, and can be turned and moved in the airflow hole. Since the outer frame 22 has a certain thickness, the through hole inside the outer frame 22 and the wall around the flue port are also at a certain distance. When the two valve covers 70 are moving in the airflow hole (not shown), the two valve covers 70 will not be blocked or interfered by the wall, thereby ensuring the normal activity function of the two valve covers 70.

[0040] It can be seen from the above that the mounting base of the utility model not only has a simple and ingenious structural design and good air tightness, but also is convenient and flexible to install, has a low manufacturing cost, and has a good adaptation effect with the flue check valve.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
