DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. The directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the accompanying drawings. They are only for the convenience of description and cannot be understood as limitations on the technical solution. The "first, second..." used are only used to distinguish the names and do not represent specific quantities and orders.

[0029] like Figure 1-4 As shown, the utility model provides a filtering device, which includes a device body 1, a filter element assembly 2, an antifreeze airbag 3 and a cover 4. The device body 1 has a cavity inside, and is provided with a water inlet 5 and a water outlet 6. Water flows into the inside of the device body 1 from the water inlet 5 of the device body 1. The filter element assembly 2 is arranged in the cavity of the device body 1. After the water is filtered by the filter element assembly 2, it flows out from the water outlet 6 of the device body 1. Under the action of the filter element assembly 2, the water quality can be effectively improved. When the environment in which the filtering device is located is relatively cold, the water stored in the device body 1 will inevitably freeze. In order to prevent the water from condensing and ice from damaging the internal structure of the filtering device, the antifreeze airbag 3 is arranged in the filter element assembly. When the water flow is about to freeze, the volume will increase and squeeze the antifreeze airbag 3. The gas inside the antifreeze airbag 3 plays a gas-liquid separation role, thereby preventing the water from condensing into ice and squeezing the filter element assembly 2. After the water flow about to freeze is blown away, the antifreeze airbag 3 that is not squeezed will open again to play a buffering role. The sealing cover 4 is covered with the device body 1, thereby realizing the detachable function of the filtering device, which is convenient for people's daily maintenance and replacement of the filter element assembly 2 or the antifreeze air bag 3.

[0030] In a specific embodiment, the filter element assembly includes a filter element connecting rod 7, a screen 8, filter particles 9 and a filter element plugging cover 10. The filter element connecting rod 7 has a downwardly opening receiving groove 11 inside, the antifreeze airbag 3 is placed in the receiving groove 11 of the filter element connecting rod 7, the screen 8 is arranged above the filter element connecting rod 7, the filter particles 9 are arranged in the screen 8, the filter element plugging cover 10 is arranged in the screen 8, and the filter element plugging cover 10 is provided with a water outlet 12. Water flows in from the screen 8, is filtered by the filter particles 9, and then flows out from the water outlet 12 of the filter element plugging cover 10.

[0031] In a specific embodiment, in order to ensure the filtering effect of the filtering device, people need to replace the filter element assembly regularly. However, in order to avoid waste of resources, a slot 13 is provided above the filter element connecting rod 7. The slot 13 includes a first slot 14 and a second slot 15. The first slot 14 is used to place the screen 8, and the second slot 15 is used to place the filter plugging cover, thereby realizing the detachable design of the filter element assembly. People only need to replace the filter particles 9 in the screen 8 regularly.

[0032] In a specific embodiment, the filter element plugging cover 10 includes a column 16 and a cover 17, one end of the column 16 is fixedly connected to the cover 17, and the other end of the column 16 is placed in the second slot 15. A plurality of water outlet holes 12 are provided above the cover 17, and the cover 17 covers one end of the screen 8, thereby ensuring the integrity between the filter element connecting rod 7, the screen 8, and the filter element plugging cover 10, which are not easily separated and fallen off.

[0033] In a specific embodiment, a cutout 18 is provided on the side wall of the filter element connecting rod 7, and the number of the cutouts 18 is preferably two. Since the filter element connecting rod 7 is long and difficult to be ejected from the mold during the injection molding process, the cutout 18 can be provided to facilitate ejection from the mold. In addition, the cutout 18 can also facilitate the flow of water in the device body 1.

[0034] In a specific embodiment, the antifreeze airbag 3 is conical in shape, and the conical antifreeze airbag 3 is more suitable for the filter element assembly. The antifreeze airbag 3 is made of silicone material. When the antifreeze airbag 3 is made of silicone material, it can further improve its wear resistance, weather resistance and temperature resistance while ensuring its function.

[0035] In a specific embodiment, a plurality of connectors 19 are provided on the device body 1, and the filter device can be stably mounted on other products through the connectors 19, for example, the filter device can be mounted on a water heater.

[0036] like Figure 5As shown, the utility model provides an instant water heater, which includes a filtering device, a control panel assembly 20, a heater 21, a thyristor 22 and a valve assembly 23. The control panel assembly 20 is connected to the thyristor 22 by signal, and the thyristor 22 is arranged on the heater 21. The thyristor 22 is used to adjust the voltage at both ends of the heater 21 and thus change the power of the heater 21. The control panel assembly 20 is connected to the valve assembly 23 by signal, so as to control the opening or opening size of the water outlet end of the valve assembly 23. The filtering device is arranged between the heater 21 and the valve assembly 23. More specifically, the water inlet 5 of the device body 1 is connected to the water outlet end of the valve assembly 23, and the water outlet 6 of the device body 1 is connected to the water inlet pipe of the heater 21. The instant water heater has the beneficial effects of the above-mentioned filtering device, which will not be elaborated in this article.

[0037] The use principle of the utility model is as follows: the antifreeze airbag 3 is arranged in the filter element assembly 2, the filter element assembly 2 is arranged in the cavity of the device body 1, and the cover 4 is covered with the device body 1. The external water flows into the interior of the device body 1 from the water inlet 5 of the device body 1, and the water flows out from the water outlet 6 of the device body 1 after being filtered by the filter element assembly 2. Under the action of the filter element assembly 2, the water quality can be effectively improved. When the environment in which the filter device is located is relatively cold, the water stored in the device body 1 will inevitably freeze, and the volume will increase, which will squeeze the antifreeze airbag 3. The gas inside the antifreeze airbag 3 plays a gas-liquid separation role, thereby preventing the water from condensing into ice and squeezing the filter element assembly 2. When the water flow that is about to freeze is blown away, the antifreeze airbag 3 that is not squeezed will open again to play a buffering role.

[0038] The filtering device provided by the utility model and other structures of the instant water heater refer to the prior art.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
