Description

Technical Field

[0001] This utility model belongs to the field of deodorizing machine technology, and in particular relates to a handheld deodorizing device. Background Technology

[0002] In daily life, new purchases of items such as cars, furniture, clothes, and shoes often have an odor, or after a period of use, such as an odor in a corner of a car or furniture, or shoes that have been worn for a long time, will more or less develop an odor. Current methods for removing odors usually involve adding deodorizing liquid to a spray bottle in a sprayer. However, since the concentration of odors is often inconsistent, the existing sprayers cannot adjust the concentration of the mist, which leads to waste of deodorizing liquid during the deodorization process. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a handheld deodorizer with adjustable deodorization concentration and convenient use.

[0004] The purpose of this utility model is achieved through the following technical solution: This handheld deodorizer includes a cavity with an air inlet and an air outlet. The cavity is equipped with a power unit that guides the air from the air inlet to the air outlet and blows it out. The air inlet of the cavity is equipped with a switching adjustment device for switching the air inlet mode. An adsorption unit for adsorbing deodorizing liquid is installed within the switching adjustment device. The concentration of deodorizing mist emitted by the deodorizing liquid in the adsorption unit is adjusted by switching the air inlet mode. When deodorizing in the cavity, air enters from the switching adjustment device and draws the deodorizing mist emitted by the deodorizing liquid in the adsorption unit into the guide channel of the cavity, and then blows it onto the surface of the object to be deodorized or into the space through the blowing end of the cavity.

[0005] The beneficial effects of this utility model are as follows: Compared with the prior art, by setting a switching and adjusting device with an adsorption unit at the air inlet end of the cavity, and adjusting the concentration of the deodorizing mist emitted by the deodorizing liquid in the adsorption unit by switching the air inlet mode of the switching and adjusting device, the concentration of the deodorizing mist blown out by the air outlet of the cavity can be adjusted. The concentration of the deodorizing mist can be adjusted in time according to the concentration of odor on site by switching and adjusting device, which has the advantages of adjustable deodorizing concentration, convenient use and convenient portability.

[0006] Preferably, the switching and adjusting device includes a base and an adjusting cover. One side of the base is installed on the port wall of the air inlet end of the cavity, and the adjusting cover is inserted into the other side of the base via an elastic plug-in unit. Both the adjusting cover and the base are provided with air inlet adjusting components for adjusting the air inlet mode, and the adsorption unit is installed on the air inlet adjusting components. With the above structure, the switching and adjusting device is more convenient to install and remove from the air inlet end of the cavity. By setting the air inlet adjusting components and installing the adsorption unit on the air inlet adjusting components, the concentration of the deodorizing mist can be adjusted in a timely manner by adjusting the air inlet mode of the air inlet adjusting components.

[0007] Preferably, the air intake adjustment component includes a ventilation protrusion disposed at the center of the base and a ventilation grille disposed on the adjustment cover. An annular groove for placing the adsorption unit is formed between the ventilation protrusion and the side wall of the base, and the ventilation grille covers the ventilation protrusion and the annular groove. With the above-mentioned ventilation protrusion and ventilation grille, the concentration of the deodorizing mist can be adjusted simply by adjusting the coverage between the ventilation grille and the ventilation protrusion, making the operation very convenient.

[0008] Preferably, the elastic plug-in unit includes a mounting hole disposed at the center of the ventilation protrusion and an elastic snap-on post unit disposed at the center of the ventilation grille. The elastic snap-on post unit is plugged into the mounting hole to allow rotational adjustment between the adjusting cover and the base, thereby adjusting the direction of the air intake channel between the ventilation grille, the ventilation protrusion, and the adsorption unit. The above structure makes it easier to assemble and disassemble the adjusting cover and the base, and makes it more convenient to adjust the direction of the air intake channel.

[0009] Preferably, the elastic snap-fit ​​column unit includes at least two elastic snap-fit ​​pieces distributed at equal intervals around the center of the ventilation grille, through which the adjusting cover is inserted into the mounting hole of the ventilation protrusion; the above structure makes it easier to assemble and disassemble the elastic snap-fit ​​column unit and the mounting hole, facilitates the replacement of the adsorption unit or the adsorption of deodorizing liquid, and makes the operation more convenient.

[0010] Preferably, the circumferential sidewall of the ventilation protrusion is provided with an adjustment slot, and the ventilation grille corresponding to the adjustment slot is provided with an adjustment strip. When the adjustment cover and the base rotate relative to each other, the adjustment strip and the adjustment slot lock together to close or open the ventilation grille and the ventilation protrusion, thereby switching the air intake mode of the cavity's air inlet. The adjustment strip and adjustment slot make it easier for the user to perceive the switching of the air intake mode of the cavity's air inlet during use. After switching, the ventilation grille and ventilation protrusion support will not loosen during the high-frequency airflow vibration of the cavity, thus ensuring a stable concentration of the deodorizing mist.

[0011] Preferably, the base has a limiting groove on its circumferential sidewall, and the adjusting cover has a limiting block on its inner sidewall corresponding to the limiting groove. When the adjusting locking strip is engaged with the adjusting locking groove, the end of the limiting block and the inner end of the limiting groove are engaged or disengaged on one side. Through the above structure, the ventilation grille and the ventilation protrusion are further limited during the closing or opening process, and the relative rotation between the adjusting cover and the base is limited, thus providing double protection. During the vibration of the high-frequency blowing of the cavity, the ventilation grille and the ventilation protrusion support will not loosen.

[0012] Preferably, the ventilation protrusion is a hollow cylindrical protrusion, and the circumferential sidewall of the ventilation protrusion is provided with a plurality of air inlets distributed at equal intervals, and the air inlets face the adsorption unit; the radial surface of the ventilation protrusion is provided with a plurality of first strip holes distributed at equal intervals around the center of the ventilation protrusion, and the plurality of first strip holes face the ventilation grille and are connected to the guide channel; with the above structure, the air intake of the cavity can be either from the first strip holes or from the adsorption unit through the air inlet, thereby meeting the requirements of the switching adjustment device for switching air intake modes.

[0020] The present invention will now be described in detail with reference to the accompanying drawings: as shown in the drawings Figures 1 to 4As shown, this utility model includes a cavity 1 with an air inlet 11 and an air outlet 13. The cavity 1 contains a power unit that guides the air from the air inlet 11 to the air outlet 13 and blows it out. The air inlet 11 of the cavity 1 is equipped with a switching adjustment device 2 for switching the air intake mode. An adsorption unit 3 for adsorbing deodorizing liquid is installed within the switching adjustment device 2. The concentration of the deodorizing mist emitted by the deodorizing liquid in the adsorption unit 3 is adjusted by switching the air intake mode of the switching adjustment device 2. When the cavity 1 is deodorizing, air enters from the switching adjustment device 2 and draws the deodorizing mist emitted by the deodorizing liquid in the adsorption unit 3 into the guide channel 12 of the cavity 1, and then blows it through the air outlet 13 of the cavity 1 onto the surface of the object to be deodorized or into the space. The adsorption unit 3 is a ring-shaped sponge embedded in an annular groove 43. The adsorption unit 3 can adsorb deodorizing liquid, perfume, or other liquids as needed. When the adsorption unit 3 adsorbs perfume, it is used as a fragrance diffuser.

[0021] The power unit mentioned above consists of a motor and a fan. The motor drives the fan to generate negative pressure in the air guide channel 12, which causes air to enter the air inlet of the cavity and blow out the air from the air outlet through the air guide channel 12.

[0022] A portable battery pack 6 for powering the power unit is inserted into the bottom of the cavity 1, which makes it easier to carry and replace the battery pack 6.

[0023] The switching adjustment device 2 includes a base 21 and an adjustment cover 22. One side of the base 21 is installed on the port wall of the air inlet end 11 of the cavity 1. The adjustment cover 22 is inserted into the other side of the base 21 through the elastic insertion unit 5. Both the adjustment cover 22 and the base 21 are provided with an air inlet adjustment component 4 to adjust the air inlet mode, and the adsorption unit 3 is installed on the air inlet adjustment component 4.

[0024] The air intake adjustment assembly 4 includes a ventilation protrusion 41 disposed at the center of the base 21 and a ventilation grille 42 disposed on the adjustment cover 22. An annular groove 43 for placing the adsorption unit 3 is formed between the ventilation protrusion 41 and the side wall of the base 21, and the ventilation grille 42 covers the ventilation protrusion 41 and the annular groove 43.

[0025] The flexible plug-in unit 5 includes a mounting hole 51 located at the center of the ventilation protrusion 41 and a flexible snap-on post unit located at the center of the ventilation grille 42. The flexible snap-on post unit is plugged into the mounting hole 51 to enable the rotation adjustment between the adjusting cover 22 and the base 21, thereby adjusting the direction of the air intake channel between the ventilation grille 42, the ventilation protrusion 41, and the adsorption unit 3.

[0026] The elastic snap-fit ​​column unit includes at least two elastic snap-fit ​​pieces 52 that are evenly spaced around the center of the ventilation grille 42. However, in order to ensure the smoothness of the rotation between the adjusting cover 22 and the base 21 and to ensure its strength, there are generally four elastic snap-fit ​​pieces 52 that are evenly spaced around the center of the ventilation grille 42. The adjusting cover 22 is inserted into the mounting hole 51 of the ventilation protrusion 41 through the elastic snap-fit ​​pieces 52.

[0027] The circumferential sidewall of the ventilation protrusion 41 is provided with an adjustment slot 44, and the ventilation grille 42 corresponding to the adjustment slot 44 is provided with an adjustment strip 45. When the adjustment cover 22 rotates relative to the base 21, the adjustment strip 45 and the adjustment slot 44 lock together, allowing the ventilation grille 42 and the ventilation protrusion 41 to close or open, thereby switching the air intake mode of the air inlet 11 of the cavity 1. The inner surface of the adjustment slot 44 is provided with at least three slots, of which the first and last slots are used to switch the odor-removing mist concentration of the adjustment device 2 to the maximum or minimum in the air intake mode. This design facilitates the user's rotation of the adjustment cover 22 and provides a certain degree of damping, allowing the odor-removing mist concentration to be adjusted by switching the air intake mode.

[0028] The base 21 has a limiting groove 23 on its circumferential side wall, and the adjusting cover 22 corresponding to the limiting groove 23 has a limiting block 24 on its inner side wall. When the adjusting locking strip 45 is locked between the adjusting locking groove 44, the end of the limiting block 24 and the inner end of the limiting groove 23 are in contact or separated on one side. That is, when one side of the limiting block 24 is in contact with one side of the limiting groove 23, the deodorizing mist concentration is the largest, and vice versa.

[0029] The ventilation protrusion 41 is a hollow cylindrical protrusion. Several air inlets 46 are provided on the circumferential sidewall of the ventilation protrusion 41, and the air inlets 46 face the adsorption unit 3. Several first strip holes 47 are provided on the radial surface of the ventilation protrusion 41, which are circumferentially distributed at equal intervals around the center of the ventilation protrusion 41. The first strip holes 47 face the ventilation grille 42 and are connected to the flow channel 12.

[0030] The ventilation grille 42 is provided with a number of second strip holes 48 that are circumferentially and equally spaced around the center of the ventilation grille 42, and the number of second strip holes 48 are all facing the ventilation protrusion 41 and the adsorption unit 3 and are connected to the flow channel 12.

[0031] The first strip hole 47 and the second strip hole 48 mentioned above are both arc-shaped strip holes. When the ventilation grille 42 rotates relative to the ventilation protrusion 41, the first strip hole 47 and the second strip hole 48 will be misaligned or overlapped. The working principle is as follows: when the first strip hole 47 and the second strip hole 48 overlap, the air intake directly enters the first strip hole 47 from the core of the strip hole and flows into the guide channel 12 of the cavity 1. This allows the blowing end 13 of the cavity 1 to blow air onto the surface that needs deodorization. The deodorizing mist concentration is at its minimum. When the first strip hole 47 and the second strip hole 48 are misaligned, the baffle of the second strip hole 48 closes the first strip hole 47. The air can only enter the surface of the adsorption unit 3 and enter through the air inlet and into the guide channel 12 of the cavity 1. This makes the deodorizing mist concentration blown by the blowing end 13 of the cavity 1 onto the surface to be deodorized the maximum. During the switching process from overlapping distribution to misaligned distribution of the first strip hole 47 and the second strip hole 48, the deodorizing mist concentration gradually increases from small to large.

[0032] The inner circumferential wall of the base 21 is provided with at least two L-shaped snap-fit ​​grooves 25 that are equally spaced. The outer circumferential wall of the air inlet end 11 of the cavity 1 corresponding to the L-shaped snap-fit ​​grooves 25 is provided with at least two snap-fit ​​protrusions 26. The snap-fit ​​part in the L-shaped snap-fit ​​groove 25 is provided with a snap-fit ​​strip 27. The snap-fit ​​protrusion 26 corresponding to the snap-fit ​​strip 27 is provided with a groove 28. The base 21 and the air inlet end 11 of the cavity 1 are aligned and rotated through the L-shaped snap-fit ​​groove 25 and the snap-fit ​​protrusion 26, so that the snap-fit ​​strip 27 and the groove 28 are snap-fitted and fixed.

[0033] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
