The invention relates to a negative pressure massage host, in particular to a negative pressure massage host with an embedded filter.

As the pace of life is getting faster and faster, modern people often do not have enough time to exercise to relax their body and mind, or they have accumulated a lot of pressure to relieve pressure. Therefore, there are many kinds of massage and stress relief devices on the market. The general negative pressure massage device includes a main unit, a hose and a vacuum cup. The two ends of the hose are respectively connected to the main unit and the vacuum cup. The user can control the vacuum cup through the main unit to pump or exhaust the skin surface. Qi, so as to achieve the effect of massage relaxation.

Because the negative pressure massage device is often used with essential oils or lotions, in order to avoid the failure of the essential oils or lotions inhaled into the host, a filter is usually attached to the hose, or the filter is installed in the pipeline of the host to achieve The role of filtering. However, users may not install an external filter due to trouble during operation, resulting in the inhalation of essential oils or lotions into the main unit; while the filter in the main unit cannot know the degree of dirt from the outside and is not easy to replace. . In addition, the general filter shares the same channel when exhausting and exhausting, so that the essential oil or lotion of the filter element may be re-discharged to the user's skin during exhausting.

In view of this, the inventor of the present invention has devoted himself to the research and application of the theory, aiming at the above-mentioned deficiencies of the prior art, to try his best to solve the above-mentioned problems, which is the goal of the present inventor's improvement.

The main purpose of the present invention is to ensure that the user is equipped with a filter for extraction and exhaust during operation, and at the same time, it is convenient to check the degree of contamination of the filter at any time and to replace it quickly and easily.

In order to achieve the above purpose, the present invention provides a negative pressure massage host with a built-in filter, comprising a main body and a built-in filter, the main body has a panel, the panel is provided with an installation hole, and the built-in filter includes a hollow cylinder and a filter element arranged in the hollow cylinder body, the hollow cylinder system is assembled or detached from the outer side of the panel corresponding to the installation holes.

The present invention also has the following effect: through the hollow cylinder of transparent material, the user can directly observe the degree of contamination of the filter element from the outside. By means of the clamping strip on the inner edge of the hollow cylinder, the frictional force when the filter element is clamped can be increased, and it is not easy to fall off. By rotating the fitting filter, each latch can be latched into the corresponding locking groove to fix the fitting filter to the adapter member. Through the magnetic attraction between the first magnetic element of the clamping portion and the plurality of second magnetic elements of the connecting portion, the embedded filter can be quickly disassembled and assembled to the adapter member. Through the setting of the anti-bleed air ring and the rubber ring, the embedded filter can be effectively sealed to avoid air leakage during suction and exhaust.
