Sub category products view

Hi, I wanna see just the products who belong to the same category (and not all the child categories products).
I tried this code in the child theme functions.php which I’ve found in the internet

function exclude_product_cat_children($wp_query) {
	if ( isset ( $wp_query->query_vars['product_cat'] ) && $wp_query->is_main_query()) {
    	$wp_query->set('tax_query', array(
            array (
                'taxonomy' => 'product_cat',
                'field' => 'slug',
                'terms' => $wp_query->query_vars['product_cat'],
                'include_children' => false
            )
		) );
  	}
}

It works great, until I open the grandchild category and I can’t see his products at all (in every grandchild category.
Do you know how to change the code in order to see each product for his own sub category?
Thanks, Itay!
