[0001] The utility model belongs to the technical field of protection devices and relates to a protection device for a pre-filter. Background Art

[0002] Nowadays, the popularity of installing pre-filters in families is very high, and the installation environments are different. Some pre-filters are installed outdoors and are exposed to wind and sun, which greatly affects the service life of the products and may also generate algae. In winter, when the products are installed outdoors, they may even freeze and crack. When the temperature difference between the indoor air temperature and the water source temperature is too large during indoor installation, condensation water will be generated on the surface of the products. Currently, most of the protection devices for pre-filters are discarded at the initial stage of installation, and they cannot protect the pre-filters in various environments.

[0003] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a protection device for a pre-filter, which is not only used for protecting the product during transportation, but also can be used for protecting the product after installation.

The concave hole 6 is circular, so that the sewage discharge knob 10 on the pre-filter inside the protection device can well pass through the concave hole 6 to reach the outside of the protection device, thus facilitating the cleaning operation of the pre-filter in time.

[0030] Inside the accessory box 3, there are multiple grooves. In the grooves, there are placed components for installing the water inlet pipe 14 of the pre-filter and components for installing the water outlet pipe 15 of the pre-filter. After assembly, the upper cover 8 and the base 13 can be tightly abutted against each other to complete the protection of the pre-filter.

[0031] The using process of the protection device for the pre-filter of the present utility model

[0032] Open the sealing box 1, take out the sleeve 2 containing the pre-filter and the accessory box 3, check whether the upper cover 8 and the base 13 of the sleeve 2 are fixed, check whether the protrusions 9 at the bottom of the upper cover 8 and the grooves 11 of the base 13 correspond one by one. After the inspection is completed;

[0033] Take out the components of the water inlet pipe 14 and the components of the water outlet pipe 15 inside the accessory box 3. After installing them with the pre-filter, make the upper cover 8 and the base 13 abut against each other tightly and seamlessly.

[0034] Pass the drain pipe through the reserved hole 7 at the bottom of the sleeve body 2 for connection.

[0035] Observe whether the condition of the pre-filter inside the sleeve body is good through the observation window 5. When using it for the first time, the pre-filter can be cleaned through the external sewage discharge knob 10, and the generated waste water will be discharged through the drain pipe. The schematic diagram after installation is as Figure 4 shown.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
