change the add basket icon on the product page, with just text “add to cart

Hi,
how to change the add basket icon on the product page, with just text “add to cart”
I use the theme “dokan”
and I see this code

Dokan: add-to-cart.php (woocommerce/loop/add-to-cart.php)

<?php
/**
 * Loop Add to Cart
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/loop/add-to-cart.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see         https://docs.woocommerce.com/document/template-structure/
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     3.3.1
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

global $product;

$icon_class = ( $product->get_type() == 'simple' ) ? 'fa-shopping-cart' : 'fa-shopping-cart';

echo apply_filters( 'woocommerce_loop_add_to_cart_link',
    sprintf( '<a href="%s" rel="nofollow" data-quantity="%s" data-product_id="%s" data-product_sku="%s" class="cat btn add_to_cart_button %s" title="%s">%s</a>',
        esc_url( $product->add_to_cart_url() ),
        esc_attr( isset( $quantity ) ? $quantity : 1 ),
        esc_attr( $product->get_id() ),
        esc_attr( $product->get_sku() ),
        esc_attr( isset( $class ) ? $class : 'button' ),
        esc_html( $product->add_to_cart_text() ),
        sprintf( '<i class="fa %s"></i>', $icon_class )
    ),
$product );
