The disclosure relates to a negative-pressure massage machine, particularly to a negative-pressure massage machine with an embedded filter.
With the faster and faster rhythm of life, people usually do not have enough time to relax or need to release accumulated pressure. Thus, there are many massage machines in the market. A related-art negative-pressure massage device includes a host, a soft tube, and a vacuum cup. Two ends of the soft tube separately connect to the host and the vacuum cup. A user may control the vacuum cup by the host to suck air from the skin or eject air on the skin so as to accomplish the effect of massage and relaxation.
Because the negative-pressure massage device is usually used with essential oil or lotion, a filter is provided outside the soft tube or in the pipeline of the host to prevent the essential oil or lotion from entering the host. However, the external filter may not be installed by the user and that causes infiltrating of essential oil or lotion to the host. The degree of dirtiness of the inside filter cannot be viewed from the outside and replacement is hard to perform. In addition, the related-art filter uses a common passage during sucking and ejecting air, so the essential oil or lotion in the filter core may be ejected to the user’s skin when ejecting air.
In view of this, the inventors have devoted themselves to the above-mentioned related art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems.
An object of the disclosure is to ensure that the ventilation is incorporated with a filter when a user is operating, and to make the degree of dirtiness of the filter be easily viewed and the filter be replaced conveniently.
To accomplish the above object, the disclosure provides a negative-pressure massage machine with an embedded filter, which includes a main body and an embedded filter. The main body has a panel with an installing hole. The embedded filter includes a hollow cylinder and a filter element disposed in the hollow cylinder. The hollow cylinder is assembled or removed corresponding to the installing hole from the outside of the panel.
The disclosure further has the following functions. By the hollow cylinder with transparent material, a user may directly view the degree of dirtiness of the filter element from the outside. The holding ribs on an inner wall of the hollow cylinder may increase the friction against the filter element to avoid unexpected separation. Rotating the embedded filter may make each latching lug latched in corresponding one of the locking recesses so as to fasten the embedded filter in the adapter. The first magnetic element of the engaging portion and the second magnetic elements of the connecting portion attract each other so that the embedded filter is easily connected to or separated from the adapter. The air sealing ring and the rubber ring may effectively seal up the embedded filter to avoid leakage when sucking and ejecting air.
The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.
The disclosure provides a negative-pressure massage machine with an embedded filter 20, which is used with a soft tube (not shown in figures) and a vacuum cup (not shown in figures). Please refer to
The main body 10 is substantially a trapezoid. A front side of the main body 10 has a panel 11 with an installing hole 111. In the embodiment, the panel 111 is further provided with a knob, a key, a buzzer, a display, a switch, etc. Designers may change the design of the panel 111 according to demands, so the disclosure does not limit it.
The embedded filter 20 includes a hollow cylinder 21 and a filter element 22 disposed in the hollow cylinder 21. The hollow cylinder 21 may be assembled or removed corresponding to the installing hole 111 from the outside of the panel 11. In some embodiments, the hollow cylinder 21 is a transparent member so that the degree of dirtiness of the filter element 22 may be directly viewed from the outside. The inside of the hollow cylinder 21 is provided with an air outlet pipe 211 and an outer connector 212 communicating with the air outlet pipe 211. Multiple air inlet openings 213 are formed between the air outlet pipe 211 and the outer connector 212. The outer connector 212 is used for connecting the soft tube (not shown in figures) to cooperate with the vacuum cup (not shown in figures) so as to guarantee the filter is used to suck or eject air when a user is using and is easy to be removed or replaced for the user. In the embodiment, the filter element 22 is, but not limited to, a cylindrical cotton filter. The filter element 22 is adapted to sheathe the outer periphery of the air outlet pipe 211 and fixed between the hollow cylinder 21 and the air outlet pipe 211. In some embodiments, an inner wall of the hollow cylinder 21 is protruded with multiple holding ribs 214 so that when the filter element 22 is fixed in the hollow cylinder 21, a periphery of the filter element 22 is slightly deformed by the holding ribs 214 and the hold the filter element 22 is firmly held in the hollow cylinder 21.
Further, the negative-pressure massage machine of the disclosure includes an adapter 30. The adapter 30 passes through and is fixed to the installing hole 111 for the embedded filter 20 to be sheathed and fastened. In the embodiment, the adapter 30 is fixed on the panel 11 by multiple screws A. In detail, the adapter 30 has a chamber 31 and an aperture 32 communicating with the chamber 31. The aperture 32 is located at an end of the adapter 30 projecting from the panel 11. An outer edge of the aperture 32 is formed with a connecting portion 33. Please refer to

In detail, the vacuum pump 50 is used to suck air for a vacuum cup (not shown in figures). The vacuum pump 50 has an air inlet hole 51 and an air outlet hole 52. The air inlet hole 51 is connected to the sucking connector 34 and the air outlet hole 52 is connected to the air outlet bar 80, so that the gas sucked by a vacuum cup (not shown in figures) and filtered by the embedded filter 20 may be ejected to outside of the main body 10 by the vacuum pump 50 through the air outlet bar 80. The pressure detecting module 41 is disposed on the circuit board 40 and connected to the air pressure detecting connector 36 to measure the vacuum degree when the vacuum cup (not shown in figures) is sucking air. A user may read the value through the display on the panel 11. The high-flow electromagnetic valve 61 is connected to the high-flow leaking connector 351 and the low-flow electromagnetic valve 62 is connected to the low-flow leaking connector 352. Both the high-flow electromagnetic valve 61 and the low-flow electromagnetic valve 62 communicate with the air inlet bar 70. Therefore, the gas sucked by the air inlet bar 70 may be ejected through different leaking connectors 35 depending on demands to achieve a change of air ejection flow. The negative ion generator 90 is connected to the negative ion emitting connector 37 so as to eject the negative ions generated by the negative ion generator 90 and the gas ejected by any one of the leaking connector 35 to further enhance the function of massage.

Moreover, when sucking air, the air flows through the air inlet channel Y of the embedded filter 20, its complete path is described as follows. Air enters though the outer connector 212 of the embedded filter 20, then flows in between the hollow cylinder 21 and the air outlet pipe 211 through the air inlet openings 213 and is filtered by the filter element 22 to filter out impurities such as oily dirt, next flows through the venting cover 26 and then enters the air inlet chamber 312 of the adapter 30 and leaves the adapter 30 through the sucking connector 34, and finally passes the vacuum pump 50 and is ejected to outside of the main body 10 through the air outlet bar 80.
In detail, when ejecting air, the air flows through the air outlet channel X of the embedded filter 20, its complete path is described as follows. Air is sucked from the outside of the main body 10 through the air inlet bar 70, then flows to corresponding one of the high-flow leaking connector 351 and the low-flow leaking connector 352 through either the high-flow electromagnetic valve 61 or the low-flow electromagnetic valve 62, next enters the air outlet chamber 311 and then flows through the communicating element 27 and the air outlet pipe 211 in order, and finally is ejected to the vacuum cup (not shown in figures) from the outer connector 212 through the soft tube (not shown in figures).
